ROVEMA uses SIKO position indicators with IO link for packaging systems
ROVEMA, one of the leading manufacturers of packaging systems in the nutrient sector, amongst others, relies on monitored size changeover using the AP10 electronic position indicators with IO link from SIKO, the specialist for industrial measurement and drive applied science.
Powdered milk formula for babies is a sensitive product that must be filled gently and safely into appropriate foil bags and outer packaging. The packaging logistics behind information technology must be idea through to the smallest detail. ROVEMA offers comprehensive turn-primal-systems for packaging processes such as these – from primary packaging in tubular bags to secondary packaging for sales and tertiary packaging for ship.
Flexibility through polish size changeover
It is important to accept as much flexibility as possible in complex plant systems, in spite of specific product characteristics, in order to be able to produce unlike variants of products, tubular bag and carton sizes. It is therefore essential that size changeovers for unlike packaging formats are smoothen to ensure production processes are as efficient and reliable equally possible. Here, Rovema relies on SIKO's AP10 electronic position indicators with IO link interface for monitored and reliable size changeover, both for cartoning machines and for form-fill-seal machines. Up to forty adjustment points may exist necessary in order to accommodate all functions to a product variant inside plough-central arrangement such as this, as designed by ROVEMA for packaging baby formula. Changeover that relies on purely mechanical position indicators is very susceptible to errors and inaccuracies. Similar competitor products were already existence used earlier ROVEMA turned to SIKO'southward electronic solution, however, they required an additionally integrated controller. This was more complicated to connect and also the more than expensive solution. The AP10 from SIKO with IO link interface saves the costs for the controller and makes it much easier to integrate the position indicators equally IO link devices into the automobile control system. Ingo Hamel, head of innovation at ROVEMA, explains, "IO link is a communication standard that is becoming increasingly widespread in the automation sector and is already being used more than and more by us as an interface for sensors and actuators. It was therefore obvious to recollect about this for the size changeover and to ask SIKO. We already take a longstanding effective cooperation in the field of mechanical position indicators." Moritz Müller, product manager PositionLine at SIKO, was pleased to deed on the suggestion, "We were also already working with IO link and thus developed the
AP10 with an IO link interface, which can be hands and safely integrated into machine control systems." Says Ingo Hamel, "We consider SIKO to be a very innovative and futurity-oriented company that develops and advances many innovations. We also reap the benefit of that."
From powder to outer carton
Infant formula is packaged in pulverisation class in pack sizes ranging from 200 to 800 grams in the entire plant mentioned at the beginning. The powder is beginning filled into corresponding bags in parallel in two form fill up and seal machines and then fed on ii tracks to a horizontal cartoning motorcar. Here, 1 or 2 numberless are placed in a folding box and provided with a dosing spoon before the box is airtight. The gear up-to-load boxes are so taken to the terminal packaging motorcar and packed into a ship carton. The last station is and then the customer's palletizing organization.
Unique values, stored in the control system
All twoscore adjustment points forth the line must always be adjusted to the new dimensions according to the corresponding packaging sizes. Most of the aligning points are located in the cartoner and terminate-of-line packaging expanse, less and then in the tubular bag auto. When a new size is needed, the corresponding recipe is selected in the controller, whereby all electronic position indicators receive the new fix points directly via the IO link interface and display them conspicuously on the back lit display. The LEDs of the displays immediately switch to cherry-red, every bit the current position is now no longer correct. The operator and so goes on to mechanically adjusts all corresponding points to the new values – another ergonomic advantage, the AP10 indicates the direction to the setpoint via the LEDs and the LCD with corresponding arrows, to make it very like shooting fish in a barrel to visualize where the operator has to move to. If the position and setpoints and then friction match exactly, the LED display changes to green – position reached. This is how all the red position indicators are moved in order to finally be able to start the new production. The advantages for the operator speak for themselves – no more than paperwork, no more long lists of values to tick off and certificate. All values are already available electronically and are transmitted directly to the position indicators. Moreover, changeover is much faster also as safer because the feedback of the LED lights is articulate. The system can only be restarted if all the corresponding position indicators low-cal up green.
Telescopic for fine aligning
In fact, in this case, the position indicators for the setpoints are given a specific tolerance range based on a nominal value. The operator has the possibility of making fine adjustment within this and the position indicators calorie-free upward greenish. If the operator leaves the area, the display switches to red. This margin can be advantageous in the issue of packaging material fluctuations in the carton area. If the temperature of the hot-cook glue fluctuates or a paper-thin box is slightly more creased, it may exist useful to slightly adjust the guides or a contact pressure by a folding tool, for instance. Co-ordinate to Ingo Hamel, this fine aligning is welcomed by the operators who know the plant and product all-time,"The tolerance range allows the operators to make an independent assessment of the state of affairs and gives them telescopic for action. This makes the processes more efficient and the employee feels involved."
IO link is on the advance
IO link is a communication standard that is gaining ground internationally. Those who use IO link for their automation benefit from many advantages. Every bit a standardized communication protocol that is subject area to an international standard, IO link is manufacturer-contained. Appropriately, devices and masters tin be adult as advice participants. Integration is possible via unproblematic indicate-to-signal connections at the everyman network level and the wiring endeavor is extremely low compared to fieldbus interfaces. The AP10 displays are regarded equally IO link devices, each of which is connected to an IO link master, which normally has eight ports. From the primary, communication with the controller is via some other high-performance protocol, in this instance SERCOS III (EtherNet/IP is as well ofttimes used by ROVEMA). Moritz Müller explains the reasons for not using EtherNet/IP throughout for advice, for case, "IO link is the much more cost-effective interface, which also makes significantly lower demands on the wiring and is thus as well easily connected." Ingo Hamel confirms the piece of cake integration, "We were very pleased that the outset commissioning worked right away – without a lot of cabling piece of work and with unproblematic parameterization and integration into the command organization." According to Moritz Müller, at that place is also a simple diagnostic function. IO link quickly shows which device may have a mistake or needs to be optimized. For this purpose, the position indicators can exist exchanged during operation without having to open up an entire network ring. The affected device can be simply disconnected and replaced by a new one cheers to the star-shaped plug connection to the IO link primary. The parameterization tin can and then be loaded directly from the IO link master into the new (identical) device and thus accepted.
Option that works
Electronic position indicators for monitored size changeover are optionally available for all ROVEMA machines and systems – which is very well accepted past customers. The customer of the packaging plant for infant formula had all 40 adjustment points equipped with AP10 displays, because the ROVEMA benefits are obvious, faster changeover times and much less documentation effort, considering everything is electronically stored and retrievable. The most important advantage is the significantly increased process reliability due to the red/green LED system; incorrect settings tin no longer occur. In fact about fifty per centum of ROVEMA customers use this option for monitored size changeover in cartoning and end packaging technology.
