Industry 4.0

How do I justify an IIoT investment?

Guest contributor: Will Healy III, Balluff

Many engineers and managers I meet with when presenting at conferences on Smart Manufacturing ask some version of the question: “How can we justify the extra cost of Industrial Internet of Things (IIoT)?” or “How do I convince management that we need an Industry 4.0 project?” This is absolutely a fair and tough question that needs to be answered; without buy-in from management and proper budget allocation, you can’t move forward. While an investment in IIoT can deliver major payoffs, the best justification really depends on your boss.

I have seen three strong arguments that can be adapted to a variety of management styles and motivations.

1) Showing a ROI through Reducing Downtime

“Show me the money!” I think everyone has a manager with this expectation. It may seem like a daunting task to calculate or capture this information, but by using a team, knowing your KPIs and applying anecdotal feedback, you can get a good initial picture of the ROI that an IIoT project will bring to the organization. Many people have shared with me that their initial project’s ROI has “funded the next project.” There is a really great article from MetalForming Magazine that discusses how exactly to do this with the tables and forms they used at ODM Tool & Manufacturing.

2) Corporate Goals for Productivity and Utilization

We can be successful getting support for a project when we link corporate goals to project goals. Smart Industry publishes a research project each year that investigates trends in the manufacturing space in regards to digital transformation initiatives. This report cites that the three top benefits manufacturers are seeing are: improving worker productivity (3rd 2016), reducing costs (1st 2016) and optimizing asset utilization (2nd 2016). These goals are driving investments and showing actual results for manufacturers both large and small. However, the report also revealed that more than half of manufacturers cite workforce skills-gap issues as their largest roadblock and this is, I believe, why we saw improving worker productivity move to the top spot. We must bring efficiency and effectiveness to the people we have.

3) Your Competitors are Investing in IIoT!

If you have a boss that worries about falling behind, this can be a motivating argument. Control Engineering recently published a study of manufacturers and how they are investing in IIoT technologies. The largest investments are coming with sensors, connectivity and data analytics. But what is most shocking is that on average IIoT budgets are $328,160, with 18% budgeting more than a half-million dollars. If you want to keep up with the rapid pace of change in the global market, an investment in IIoT is a requirement to remain competitive.

If you are looking for support and partnership on your IIoT projects, we are experienced at utilizing IO-Link, smart sensors and RFID to enable Industry 4.0 and Smart Manufacturing projects.

Economical and intelligent: Handling solutions re-conceived

Guest contributor: Andreas Gryglewski, Bosch Rexroth

The market for handling and robotic solutions is highly price-driven, yet still leaves room for disruptive ideas. Bosch Rexroth provides proof of this with an advanced solution package for Cartesian kinematics. It combines an economical industrial controller with state-of-the-art web technology and assured instruction via a standard tablet. The result: minimum investment costs and maximum efficiency – before and during operation.

Manufacturers of handling solutions for loading and unloading face fierce competition. The volume market demands cost-optimized, rugged and user-friendly solutions that optimally fulfill all requirements in terms of accuracy and cycle times. In addition, users expect quick commissioning with as little programming, instruction and training expenditures as possible. A high degree of productivity and flexibility is also required for the operational phase in order to reduce downtime and so that format or process changes can be more quickly implemented.

All of these requirements are addressed by Bosch Rexroth with a particularly economical solution package for Cartesian kinematics that combines a high-performance motion controller with state-of-the-art web technologies and innovative value-added features. The automation experts make the solution package even more economical with an especially clever idea: users can perform the setup and assured teaching-in on any standard commercially available tablet.

Industrial control, web technology, consumer tablets

In its solution package for Cartesian kinematics, Bosch Rexroth combines a powerful motion controller with modern web technologies and innovative value-added features.

The disruptive solution approach for Cartesian handling from Bosch Rexroth is particularly suitable for machinery manufacturers and end users who want to implement flexibly and reliably adaptable pick-and-place tasks in a short time and at a low cost. Examples include the loading and unloading of injection-molded parts, the sorting of workpieces, or a wide range of intralogistics applications. Bosch Rexroth combines its proven industrial controller with a webserver and a bracket for a typical standard tablet, by means of which the user can visualize the connected handling solution and – graphically-supported – program, teach-in and adjust it as needed. The solution package is comprised of other basic components such as compact servo motors and drives for the kinematics movement, as well as a safety controller for connecting to the tablet bracket for safe teaching-in. From a single source, Bosch Rexroth also optionally offers the mechanical equipment, includinglinear axes with a belt or ball-screw drive and grabbers.

The utmost in connectivity and IT security

In its new handling solution, Bosch Rexroth placed special emphasis on the two key properties of i4.0 –connectivity and IT security. While the optional IoT Gateway ensures the horizontal and vertical networking, the security router with a newly developed IoT firewall, which is also optional, guarantees secure communication between the tablet and controller. Consequently, unauthorized persons can neither log into the controller nor can a virus attack the controller or spread throughout a company’s IT network.

Bild_2_21263-1200x800

Thanks to the newly developed solution packages, handling systems from Bosch Rexroth can be more quickly commissioned, easily programmed, and taught most economically using standard tablets.

Easy commissioning without parameterization

One of the numerous unique features is the operating concept for the handling solution: Immediately after a servo motor is connected with a drive, the latter reads out the stored parameter set from the feedback memory and thus already has all the characteristic data of the mechanical equipment. The result: a considerable time savings and prevention of errors during commissioning, because the user no longer has to manually enter up to 70 parameters. When Rexroth mechanical equipment is ordered in the future, the parameters will be stored in the feedback memory of the motor while still in the plant. If the user puts his own mechanical equipment into operation; the associated parameter file can also be stored in the feedback memory and is efficiently read into the drive upon connecting.

Safe teaching-in using a standard tablet

The disruptive character of the new handling solution becomes clear during setup, which can be performed wirelessly with almost any consumer tablet. It is expeditiously fastened in a bracket especially developed by Bosch Rexroth for teaching-in, which can be adjusted to the respective size and securely encloses the mobile device. On the top left is a combination emergency stop and enabling button that makes reliable and comfortable teaching-in possible for the user. While the left hand holds the tablet and can press the red button, the right hand is free for other operational tasks. The visualization and operation of the handling system is web-based and applies the HTML5 standard, hence is independent of the tablet OS. An optional security router with an integrated firewall provides for IT security.

Programming without programming knowledge

Bosch Rexroth also made the process programming, which precedes the teaching-in sequence, as uncomplicated as possible. Because it uses the graphical programming language Google Blockly, as is the case with the tablet, no programming skills in conventional terms are required. In order to move an axis from point A to point B, for example, only the start and end positions need to be specified, and a line to connect them with each other. The grabbers are also opened or closed by means of graphical elements. Thanks to variables, logical expressions and loops, it is possible to easily specify and clearly represent various processes, also complex ones if necessary.

Features for increasing productivity and quality

Positively contributing to the performance of an especially economical operating phase of the new handling solution are its versatile functions and expansion options. These ultimately also afford the user a high degree of flexibility for changes in process or format. For example, the Active vibration damping function, which provides greater product quality in combination with a sensor, or initiates the exact countermovements in the open-loop process in the linear module in order to prevent undesirable vibrations or to move sensitive products. Thus, for instance, the utmost in accuracy can be achieved when loading and unloading using the grabber sparing the mechanical equipment for a longer service life.

Preventive maintenance and IoT integration

Preventive maintenance can also be cost-efficiently realized in combined usage with the optional IoT Gateway. In order to collect data for analysis and evaluation of the service life, the motor decoder can also be used as an intelligent sensor. If the motor revolutions are converted into linear movements, the timing for lubrication intervals or the replacement of components can be derived, for example. Communication standards such as OPC UA can provide for easy integration into customer-specific IoT systems as needed.

Economical in every way

The solution package is especially suited for pick-and-place tasks that must be quickly and flexibly adaptable – such as for the loading and unloading of injection-molded parts, the sorting of workpieces, or for various intralogistics applications.

 

With the new solution package, Bosch Rexroth introduces a fresh impetus into the competitive market for Cartesian handling. Automation expertise, modern web and IoT technologies, and productivity-enhancing features are combined in a rugged and practical solution concept that takes into account current and future market requirements, and which generates disruptive energy. Consequently, machinery manufacturers and end users find quick and very economical way to implement a reliable, efficient and flexible handling solution that can be commissioned, taught, and adapted to current requirements without any significant knowledge of programming and parameterization.

Innovative approaches of the new handling system:

  • A comprehensive economic package comprising industrial controller, servo motor, drives, security zone module and teaching-in bracket for consumer tablets
  • Maximum security through a router with firewall (optional)
  • Minimal total cost of ownership thanks to:
    • Commissioning without the need for parameterization: Drives automatically read stored mechanical parameters when connected with a motor
    • Device-independent visualization and operation (HTML5)
    • Safe teaching-in bracket for consumer tablets
    • Simplified process flow design without programming knowledge, thanks to Google Blockly
  • Added value functions for productivity and quality – for example vibration absorption
  • Prepared for data tracking for preventive maintenance
  • Easy integration into IoT systems through open interfaces such as OPC UA

Innovative automation solutions for additive manufacturing 2.0

Guest contributor: Peter Berens, Bosch Rexroth

Additive manufacturing is a growth market – sales worth tens of billions of euros are expected by 2020. However, innovative automation solutions are needed if this disruptive technology is to achieve a breakthrough and make the leap from prototype construction and toolmaking to industrial mass production.

If machine manufacturers want to achieve the productivity needed for mass production, they need to reduce the amount of manual work involved, the reject rate and the quality assurance outlay and successfully integrate the machines into the production line. Both challenges can be met through high-performance, intelligent and connective automation.

IoT as a key technology

In the factory of the future, AM machines will be connected horizontally and vertically to higher-level and neighboring IT systems. When it comes to the industrial Internet of things, Bosch Rexroth relies on open i4.0 standards such as OPC UA. With full server/client functionality, processes, cycle times and energy consumption can be evaluated in real time and optimized to achieve better productivity and quality. In conjunction with intelligent algorithms in drive and control technology, Bosch Rexroth also carries out predictive maintenance.

3D printing and the factory of the future

Thanks to decentralized intelligence, drive technology without control cabinets and open standards, the next generation of AM machines is ready for the factory of the future. Wireless communication and modular production lines increase flexibility while reducing set-up times. As a result, the factory layout can be geared to current and future requirements. The next logical step is the decentralization of the control system which will then receive its programs as necessary from the cloud.

What the hardware must be capable of

Whether it be metal, plastic or ceramic: the output in the relevant AM procedure depends very much on the performance of the CNC or motion control system. The shorter the cycle times, the more quickly the NC programs run. The higher the performance, the quicker 3D data can be computed on the CNC and process data collected and processed in real time. The MTX CNC system from Rexroth achieves this with a combination of a high-performance dual core processor and decentralized intelligence allowing fast reaction times. As a result, many additional tasks can be performed by the machine. Planning, programming and the commissioning of all system components take place in a standardized manner via IndraWorks Engineering.

Abbildung_2_Werkstücke-768x257

Software makes all the difference

In order to be able to control the application of additive materials precisely and to influence it easily with process variables, the control software too must be particularly powerful. The MTX system software includes numerous AM-specific CNC functions for this purpose. These include an intelligent temperature control system and a 3D online simulation with collision recognition which automatically visualizes the construction time, positioning and printing head travel. The standardized G code is supported by any slicer software. Integrated NC encoding systems protect manufacturer-specific know-how.

Digitizing the workflow

Another key development area is the digitization of the workflow with typical tasks such as print configuration, job management, machine monitoring including online process modification or controlling intralogistics. Because this is not possible without interfaces to the software programs involved (e.g. CAD/CAM systems or simulation solutions), the MTX CNC system has an open system architecture and the Open Core Interface. As a result, machine operators can easily integrate their workflows. In a pre-production context, there are numerous benefits including material simulations or the certification of quality-related parameters. The CNC system thus fits seamlessly into simulation environments as “hardware in the loop”.

Industrial 3D printing in practice

Norsk Titanium AS demonstrates just how efficient industrial 3D printing can be. The world’s leading provider of additive manufacturing technologies for aerospace-grade titanium established the first additive production facility on an industrial scale. In its Rapid Plasma Deposition™ machines, an MTX system controls not only plasma burners but also ten servo axes for producing components and conveying or handling the titanium wire. The MTX system also takes care of process optimization in real time by evaluating sensors and calculating correction values. Bosch Rexroth contributed to the partnership through the experience that it gained during more than 100 group AM projects along with various system components such as drive controllers, supply units, motors and linear systems including the IMS high-precision integrated measuring system.

The German machine tool manufacturer Weisser presented its Weisser additive manufacturing exhibit for the first time at the EMO 2017 and the Metav 2018. Equipped with an additive friction welding unit (AFW), it allows fine layers of metal to be deposited on metal materials and then precision-machined using metal-cutting techniques. As a result, the final contour is maintained with minimal material use. This technology too benefits from the MTX CNC system whose user interface can be integrated seamlessly into the multi-touch operating panel thanks to the open architecture.

3Abbildung_1_PanelMaschine-768x512

The future will be even simpler

With high-performance and high-connectivity automation solutions, industrial 3D printers will be fast and reliable enough for use in mass production. Open interfaces will help to digitize workflows. IoT connectivity is paving the way for the factory of the future. At the same time, experienced system partners such as Bosch Rexroth who provide not only engineering and application support but also complementary technologies such as decentralized drive or linear technology with integrated sensor systems can help manufacturers to acquire the necessary know-how.

5 Ways Flexible Manufacturing has Never Been Easier

Guest Contributor: Tom Rosenberg, Balluff

Flexible manufacturing has never been easier or more cost effective to implement, even down to lot-size-one, now that IO-Link has become an accepted standard. Fixed control and buried information is no longer acceptable. Driven by the needs of IIoT and Industry 4.0, IO-Link provides the additional data that unlocks the flexibility in modern automation equipment, and it’s here now!  As evidence, here are the top five examples of IO-Link enabled flexibility:

#5. Quick Change Tooling: The technology of inductive coupling connects standard IO-Link devices through an airgap. Change parts and End of Arm (EOA) tooling can quickly and reliably be changed and verified while maintaining connection with sensors and pneumatic valves. This is really cool technology…power through the air!

#4. On-the-fly Sensors Programming: Many sensor applications require new settings when the target changes, and the targets seem to always change. IO-Link enables this at minimal cost and very little time investment. It’s just built in.

Image 2

 

#3. Flexible Indicator Lights: Detailed communication with the operators no long requires a traditional HMI. In our flexible world, information such as variable process data, timing indication, machine status, run states and change over verification can be displayed at the point of use. This represents endless creativity possibilities.

#2. Low cost RFID: Radio Frequency Identification (RFID) has been around for a while. But with the cost point of IO-Link, the applications have been rapidly climbing. From traditional manufacturing pallets to change-part tracking, the ease and cost effectiveness of RFID is at a record level. If you have ever thought about RFID, now is the time.

7_1_Produktionsdaten_Dokumentieren

 

#1. Move Away from Discrete to Continuously Variable Sensors: Moving from discrete, on-off sensors to continuously variable sensors (like analog but better) opens up tremendous flexibility. This eliminates multiple discrete sensors or re-positioning of sensors. One sensor can handle multiple types and sizes of products with no cost penalty. IO-Link makes this more economical than traditional analog with much more information available. This could be the best technology shift since the move to Ethernet based I/O networks.

8_1_induktiver_Abstand

So #1 was the move to Continuously Variable sensors using IO-Link. But the term, “Continuously Variable” doesn’t just roll off the tongue. We have discrete and analog sensors, but what should we call these sensors? Let me know your thoughts!

New Design for Hydraulic Power Units

Guest contributor:  Andreas Günder, Bosch Rexoth

Optimum power, less installation space: Thanks to new intellectual and design approaches, compact hydraulic power units increase the economic efficiency of machine tools.

Powerful force in a very confined space

In the production world, hydraulics are firmly established. Machine tool manufacturers appreciate hydraulics for their high power density, toughness and modular design. In the lower performance range up to 4 kW, however, there are also some challenges. Since the installation space is often limited, designers and technical purchasers are constantly looking for increasingly compact solutions.

Installation space is valuable

The demand for compact hydraulic drives is not only due to the structurally limited flexibility regarding extensions, modernization measures and refittings but also due to the requirements regarding acquisition costs and assembly times or structural extensions of the working space with given machine dimensions. In addition to the level of integration of the functions, energy efficiency often plays an important role as well. Last but not least, many manufacturers are following the miniaturization trend. If workpieces become increasingly smaller, the moved mass of the machine tool has to be decreased accordingly.

“Installation space eaters” hydraulic power units

To reduce the installation space, solution manufacturers can start mainly with the following components: hydraulic power unit and control cabinet. When considering this split, it becomes evident that compact power units which are also easy to integrate require completely new design approaches to eliminate all features which waste unnecessary space in the performance spectrum up to 4 kW and to ensure that the units are still compatible with many different machine designs.

Highly integrated design approaches

The features of such innovative design concepts according to the EU Eco-Design Directive 2009/125/EC for example include a tank which is optimized for efficient degassing and reduces the oil volume by up to 80 percent. A much more decisive factor for gaining space is, however, that all functions can actually be integrated in one small power unit – from an economic variable-speed drive for demand-based power output to sensor technology with filling level, temperature, pressure and filter contamination sensors to a completely wired frequency converter.

Bosch_Infografik_EN-1200x849 (1)

Compact and ready for Industry 4.0

For the future viability of this approach with regard to Industry 4.0, a data interface is essential as well. Only with permanent condition monitoring can the operating conditions be optimized comfortably and relevant faults be detected early on. With this equipment, the user only has to connect the electric power, the data interface and the hydraulic supply during installation and the hydraulic power unit is ready for operation

New cooling with heatpipe

So-called heatpipes are considered to be a space-saving innovation regarding the cooling of hydraulic power units. Their high-performance passive thermal conduction allows for a further reduction of the frame size. The heatpipes absorb the thermal energy of frequency converter, motor and hydraulic oil and efficiently transfer it to a central heat sink such as e. g. cooling water…
This ensures an intelligently optimized thermal management within the hydraulic power unit and optimally utilizes the cooling power of the cooling water. There is no need for a separate hydraulic circuit for oil cooling. This reduces installation space, noise emissions, energy consumption and possibilities for leakage.

Heatpipe – Functional principle

Basically, a heatpipe consists of air-tightly sealed copper pipes with underpressure. Inside, there is a medium which transfers thermal energy. In the temperature range of hydraulic power units, the medium may be e.g. distilled water. The boiling temperature of the water is significantly reduced by the low pressure within the heatpipe, which means that a boiling or condensation process can already take place at low temperatures.

Functionality: If you dip the heatpipe for example in hot hydraulic oil, the thermal energy at the lower immersed part of the heatpipe is transferred to the water. The water exceeds the boiling point, evaporates and absorbs a large amount of thermal energy with low temperature difference (latent heat). The water steam rises to the upper part of the heat pipe which is cooled by e. g. a cooling element. Here, the water steam condensates and gives off the thermal energy to the cooling water. Thanks to the latent heatabsorption and dissipation, the thermal conductivity of heatpipes can be up to 1000 times higher than the thermal conductivity of copper pipes. Due to the high elasticity of the copper pipes, the heat pipe can be easily shaped. In this way, ideal heat paths can be formed inside the hydraulic power unit and the installation space can be considerably optimized. Similar application ranges with equal optimization potential can be found in computer technology. Here, the thermal energy in laptops caused by heat sources such as the CPU are transferred to the central cooling elements using heatpipes.

Grafik_Heatpipe_EN.jpg

Plug & Play: no control cabinet

The frequency converter has a high potential for gaining installation space as well. If it has already been equipped with Multi-Ethernet interface for Sercos, Profinet and other standards by the manufacturer, machine and plant manufacturers are able to reduce the control cabinet requirement for the hydraulic unit by up to 100 percent. As a precondition, however, the sensor technology and the motor in the power unit have to be wired to the frequency converter in such a way that the frequency converter can control the hydraulic pressure autonomously. This means that the control cabinet can not only be designed with smaller dimensions. Sometimes it can even be completely omitted together with the corresponding installation effort and related sources of error.

Conclusion

Fully integrated small power units based on a completely innovative design approach for the performance range up to 4 kW provide machine and plant manufacturers with the advantages of hydraulic drives with very little space requirements. As an alternative to purely electrical solutions, the required energy can be converted into a linear movement in a precise and costeffective manner directly at the working area using a simple hydraulic cylinder. If sensor technology, frequency converter and data interface are integrated as well, users not only benefit from comprehensive condition monitoring but also from a significantly reduced control cabinet footprint or even from a design without control cabinet.

Predictive Maintenance for Zen State of Manufacturing

Guest contributor: Shishir Rege, Balluff

In a previous entry, Mission Industry 4.0 @ Balluff, I explained that the industry4-0two primary objectives for Balluff’s work in the area of Industry 4.0 are to help customers achieve high production efficiencies in their  automation and achieve  ‘batch size one’ production.

There are several levers that can be adjusted to achieve high levels of manufacturing efficiencies in the realm of IIoT (Industrial Internet of Things). These levers may include selecting quality of production equipment, lean production processes, connectivity and interoperability of devices, and so on. Production efficiency in the short term can be measured by how fast row materials can be processed into the final product – or how fast we deliver goods from the time the order comes in. The later portion depends more on the entire value-chain of the organization. Let’s focus today’s discussion on manufacturing – inside the plant itself.  The long-term definition of production efficiency in the context of manufacturing incorporates the effectiveness of the production system or the automation at hand. What that means is the long-term production efficiency involves the health of the system and its components in harmony with the other levers mentioned above.

The Zen state of manufacturing – nothing important will come up on Google for this as I made this phrase up.  It is the perfect state of the entire manufacturing plant that continues production without hiccups all days, all shifts, every day. Does it mean zero-maintenance? Absolutely not, regular maintenance is necessary. It is one of those ‘non-value added but necessary’ steps in the lean philosophy.  Everyone knows the benefits of maintenance, so what’s new?

Well, all manufacturing facilities have a good, in some cases very strictly followed maintenance schedule, but these plants still face unplanned downtimes ranging from minutes to hours. Of course I don’t need to dwell on the cost associated with unplanned downtime. In most cases, there are minor reasons for the downtime such as a bad sensor connection, or cloudy lens on the vision sensor, etc. What if these components could alert you well in advance so that you could fix it before they go down? This is where Predictive Maintenance (PdM) comes in. In a nutshell, PdM uses actual equipment-performance data to determine the condition of the equipment so that the maintenance can be scheduled, based on the state of the equipment. This approach promises cost savings over “time-based” preventive maintenance.

PowerSuppliesIt is not about choosing predictive maintenance over preventive maintenance. I doubt you could achieve the Zen state with just one or the other. Preventive and predictive maintenance are both important – like diet and exercise. While preventive maintenance focuses on eliminating common scenarios that could have dramatic impact on the production for long time, predictive maintenance focuses on prolonging the life of the system by reducing costs associated with unnecessary maintenance.  For example, it is common practice in manufacturing plants to routinely change power supplies every 10 years, even though the rated life of a power supply under prescribed conditions is 15 years. That means as a preventive measure the plants are throwing away 30% life left on the power supply. In other words, they are throwing away 30% of the money they spent on purchasing these power supplies. If the power supplies can talk, they could probably save you that money indicating that “Hey, I still have 30% life left, I can go until next time you stop the machine for changing oil/grease in that robot!”

In summary, to achieve the zen state of manufacturing, it is important to understand the virtues of predictive maintenance and condition monitoring of your equipment. To learn more visit www.balluff.us.

The 5 automation trends in the packaging industry

Guest contributor: Hans Michael Krause, Bosch Rexroth

Visual_EN_2538x1908_144-1250dpi.png

i4.0 in practice: the 5 automation trends in the packaging industry

Next-generation packaging machines are being designed without control cabinets and are increasingly vertically and horizontally connected. Big data analyses, smart maintenance and model-based engineering have unleashed tremendous potential. But even conventional automation tasks can be handled more easily with open interfaces and integrated functions. What are the five major automation trends in detail?

What the packaging lines of tomorrow will be able to do

When I look at the highly dynamic packaging industry, I see four major challenges faced by machine builders: more individuality when it comes to packaging, more flexibility in terms of formats, higher availability and less space required for machines and lines. These challenges lead to five major trends in automation:

(1) Connected – the connectivity trend

33640111-1200x800

As a user, I need transparency, whether I want to improve system availability through smart maintenance, make my line more flexible, or optimize complex packaging processes. Without knowledge of subprocesses and plant conditions, I can’t analyze anything – neither on premise nor via the cloud. Modern automation technology and sensor systems now provide all the necessary data. I have to retrofit existing systems, but preferably without the need for programming or intervention in the automation. The IoT gateway fulfills this requirement extremely elegantly and can be set up in just five minutes. Machine builders can also opt for Starter Kit, which includes the Software Production Performance Manager (PPM), for a complete analysis platform from a single source.

The sweet side of Industry 4.0

There is also enormous potential in cross-vendor and system-wide networking via IIoT protocols such as MQTT or the open i4.0 standard OPC UA. At interpack, four machine builders and Bosch Rexroth will showcase the “ChoConnect” project as an exciting example of authentic M2M communication: Four locally distributed exhibition machines from LÖSCH Verpackungstechnik, SOLLICH, THEEGARTEN-PACTEC and WINKLER and DÜNNEBIER Süsswaren exchange information as a virtual production line for chocolate products using OPC UA in accordance with the Weihenstephan standard and create an end-to-end transparent value chain at the shopfloor level – without the need for an MES or control system. The individual steps of mass processing, molding, primary and secondary packaging automatically adjust performance according to individual capacities. The production process becomes more flexible; system efficiency increases.

Merging of automation, IT and IIoT

The fact that inflexible line PLCs will soon be obsolete is also a consequence of a merging of automation, IT and IIoT. With open interfaces such as Open Core Interface, ERP systems can be directly linked to machine automation, simplifying inventory management for machine components. Obviously, there must be also be a security strategy for regulating access to the control system.

(2) Simple – Make it simple!

The current trend towards fewer personnel per line has increased the need for intuitive control units such as HMI with multi-touch. Transparent and seamless visualization solutions are required – on the production line itself and at other locations in the company – in order to continuously improve processes and respond quickly when necessary. The ActiveCockpit interactive communication platform shows that such solutions are already available today.

Companies often need the ability to easily integrate new machines or lines into existing systems – this can already be done mechanically using standardized chain conveyor systems such as VarioFlow plus in combination with the MTpro planning tool. In the future, open M2M interfaces will allow for easy electrical integration.

With the growing need to simplify diagnostics and maintenance, we will see even more web-based service tools and innovative LED concepts at machines in the future. Augmented and virtual reality are sure to play a part here, too. It has been repeatedly demonstrated at trade shows how the digital twin integrates itself into the real picture using open interfaces so that complex technical relationships can be visualized and understood more quickly. A product orientation module for beverage packages by WestRock will be showcased at interpack.

(3) Efficient – end-to-end digital engineering

Ever more complex design needs and shorter time-to-market requirements are fueling the demand for model-based engineering with simulations and virtual commissioning. As a technology partner with industry expertise, Open Core Engineering not only ensures seamless integration of the machine control with simulation platforms such as MATLAB/Simulink or 3DEXPERIENCE by Dassault Systèmes. For immediate creation of a digital twin that can be simultaneously used by mechanics, electricians and software programmers, Bosch Rexroth delivers digital behavior models of its automation products as standard.

Bosch Rexroth also provides a comprehensive library of prepared technology functions along with the machine control. By emphasizing parameterizing instead of programming, flow wrappers, secondary packaging systems, fillers or sealing machines can be commissioned more quickly. Integrated standard kinematics and functions for delta, parallel and palletizing robots are also available. Object-oriented PLC programming and high-level languages, such as Java and C++, facilitate creation of the machine control software. The controllers feature a web server for easy integration of Internet technologies such as visualization using HTML5. Of course, standardized programming templates support the creation of machine programs following OMAC/PackML standards as well as the Weihenstephan standard and PLCopen.

(4) Adaptive – the adaptivity trend

What if the packaging line automatically adjusted the product stream in the event of a fault, instead of jamming and displaying a lot of error messages? Prefabricated software functions such as intelligent infeeds or product grouping are already available, even for these trend-setting M2M scenarios. For the use of robots and flexible transport system a separate controller is not needed anymore. These are managed by the standard machine controller, and the number of interfaces and the effort required to use transport systems or robotics are reduced.

In view of increasingly complex packaging processes, there is also a need for machines to automatically adjust to their environment. Machines require Smart Sensor Nodes with MEM technology like XDK in order to “learn” from their current state. Virtual sensors like servo motors and drives, including the intelligent MS2N servo motor, provide useful information.

Last but not least, next-generation packaging machines automatically adjust to the current format and regulate process speed as well as product handling. Adaptive software functions have also been developed for this scenario of the future. The spectrum ranges from flexible electronic cams in the machine control (FlexProfile), drive functions such as auto-tuning and anti-vibration to frequency response measurements and innovative filter functions for minimizing resonance frequencies in mechanical parts.

(5) Cabinet-free – much more than just space saving

This trend in packaging is not just about saving space in the automation technology, machine footprint and control cabinet space. Instead, it’s about a modular machine configuration that allows machine operators and customers to respond flexibly to different requirements. The individual modules are connected to one another only by a single hybrid cable and can be easily integrated into the machine or retrofitted later. This reduces the installation area and increases servo density in favor of greater flexibility. Installation space, cabling and maintenance costs are also reduced. Such modular approaches are especially useful for secondary packaging and rotary machines such as filling and capping machines as well as retrofit projects.

Solutions for these packaging trends are already available. Use them now!

Manufacturers and users of packaging machines already have numerous options for boosting their competitiveness through intelligent and connected automation solutions. But to achieve this, they need an industry-oriented, expert partner with a broad ecosystem of solutions.
