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

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. At interpack 2017, Bosch Rexroth will give visitors the opportunity to experience the trade show theme of “Connected Automation i4.0 now live in all of its facets – including modern networking, simple design, model-based engineering and groundbreaking service. The future of automation has already begun and is ready for “installation” in the latest generation of packaging machines. Now!

The Digital Improvement Process in Three Steps

Guest contributor: Marcel Koehler, Bosch Rexroth

Industry 4.0 solutions enable production employees to digitally replicate and implement a continuous improvement process, in order to increase output, improve product quality and reduce costs. But how do I implement a first use-case? How do I ensure the necessary plant transparency? And how do I configure the monitoring and evaluation system? Quite easily – in three steps, with easy to set up tools and tailored support by experienced experts.

The focus is on people.

There are fundamental principles that were in place long before digitalization. Robert Bosch once said: “People should always strive to improve the existing conditions. No one should merely be content with what they have achieved; instead they should always aspire to do what they do even better.” Today, as in the past, the path to continuous improvement of production processes starts with people. Improving quality, reducing costs or boosting output requires at least one person to design, monitor and readjust the continuous improvement process. This person defines the essential information, keeps track of it, evaluates it, intervenes when necessary and draws conclusions, in order to adapt the process. With the arrival of Industry 4.0 and the Internet of Things (IoT), however, we now have new tools at our disposal. Tools such as IoT Gateway, which collects a variety of data without interfering with the machine logic, as well as the analysis and evaluation solutions associated with it, including the Production Performance Manager, which visualizes and evaluates the data, initiates the required actions to be taken, and simplifies the review and adaptation of the improvement process.

 

Step 1: Workshop in the company

But how do I use these tools? And how do I implement a first exemplary use-case, in order to gradually introduce it? New knowledge is transferred particularly effectively from person to person, just as in Robert Bosch’s time. In line with this principle, an experienced expert comes to the company and demonstrates the typical procedure step by step as part of the Production Performance Starter Kit from Bosch Software Innovations. In the one-day workshop, he explains the digital tools as well as typical use-cases and views the production plant together with the customer. The result of the joint workshop is at least one concrete use-case, including the solution design. The desired benefits will be examined once again and potential hurdles identified. According to the same formula, the customer can later find, develop and implement additional use-cases.

infografik_ENG_16_9_img_w1184_h666The IoT Gateway collects data from various data sources and natively transfers it to the analysis and evaluation software (Production Performance Manager).

Example of a first production performance use-case

A practical example from a concrete workshop: the condition-based monitoring and maintenance of a heat exchanger. If the heat exchanger becomes clogged due to deposits, approximately 1,500 parts become defective and the plant is forced to shut down for two hours for maintenance. An early warning system should be installed, in order to prevent production rejects and unplanned downtimes. A direct measurement of the flow rate in this plant is not possible, however, which is why temperature sensors are installed before and after the heat exchanger. The IoT Gateway, which is also installed in the line, collects the sensor data and transmits it to the Production Performance Manager, where the temperature difference is determined and compared with threshold values in order to indicate contamination. All measured values are visualized centrally for the employees responsible. When the pipes begin to clog, the system transmits a warning signal or assigns a maintenance ticket to the appropriate qualified personnel.

Step 2: Implement yourself with remote support

In the second step of the Production Performance Starter Kit, a senior consultant from Bosch Software Innovations installs the Production Performance Manager via remote access to the customer’s hardware. In doing so, at least one machine is integrated as a prototype, in order to prepare the user for scaling the solution later on. The demo license is valid for three months and up to ten machines are supported. In addition, four days of remote support are included for the Production Performance Manager. Depending on the technical infrastructure, the shopfloor integration can be done in one of three ways: via individual integrators to be programmed, via PPMP-compatible controllers or system-independent integration via the IoT Gateway from Bosch Rexroth, a universal connector that communicates natively in the open source protocol PPMP in addition to other protocols. Via the web-based user interface, the user manages the sensors, defines preprocessing of the collected data if necessary, and configures forwarding to the target system, in this case to the Production Performance Manager.

Step 3: On-site user training

After configuring the infrastructure, one last step remains, in which the employees learn to successfully apply the software. This takes place as part of a detailed user training course with an experienced trainer who comes to the location for one day. After this training, participants are able to gain quick access to machine data via visualization, set up simple automated analyses and evaluations, and define intelligent, data-driven actions based on the results. Following the idea of continuous improvement, they are, as the key stakeholders of their digital improvement process, also qualified to review the actions for effectiveness and efficiency. Thanks to the transparency this provides, the user now has a valuable Industry 4.0 tool for their daily work.

Gradual scaling after only three months

Photo_PI_014_17_IoT_Gateway_HM-1200x844

After only three months, employees arrive at the decisive point, from which they scale the prepared solution and repetitively connect additional machines and entire lines. As costs steadily decrease, the benefit increases disproportionately in the long run as the transparency gained gradually extends across all bottlenecks. In this manner, the production management of Bosch’s Pecinci plant (Serbia) succeeded in sustainably improving the stability of a complex coating process for wiper arms. The IoT Gateway collects sensor and controller data, such as humidity or paint consumption, and forwards the data to the Production Performance Manager. The software analyzes this data and compares it with defined threshold values, in order to optimize the plant availability of the coating plant, which consists of ten individual stations. A track & trace function, which allows conclusions to be drawn from the finished product about quality-relevant sub-processes, is planned as a follow-up project to the continuous improvement of product quality.

Do not be afraid of software! Try it out now and get started.

With the Production Performance Starter Kit, the hurdles to implementing digital processes for continuous improvement are greatly reduced. Any fears associated with the digital toolkit are completely unfounded. The IoT Gateway and the Production Performance Manager do not require any programming knowledge for daily application. Together with the methodical knowledge and practical support of our experts, companies acquire the knowledge necessary to implement their first use-case, scale the solution and tackle additional improvement projects in only three months. Robert Bosch surely would have relished the idea!
