The 360-degree solution for plastic extruder machines PROCESSING PLASTICS
When it comes to selecting drives for plastics machinery, customers expect a complete automated solution
C
ustomers in the plastics industry expect a complete solution for the automation of their machines. Tey want to implement a system with
coordinated components. KEB Automation provides a complete
tailored solution for machine builders, including servo motors, gear motors, permanent magnet brakes, drive controllers and PLCs. In the field of extruders and injection moulding machines, for example, the company supplies not only the hardware in the form of HMIs, PLCs, servo motors and drive controllers with integrated functional safety, but also the software including appropriate visualisation. To save time and resources in their
own software development, the firm’s customers can use an existing software core to build additional functions on top. Tis gives SMEs the opportunity to bring their machines up-to-date with a multitude of features already implemented in advance, without them having to create complete control software.
When developing its software solution
for extruders, for example, KEB focused it attention on compliance with Euromap standards, so that it’s ready for use in Industry 4.0 applications due to the open interfaces. Te machine can simply be connected to the Internet via a router, enabling remote maintenance and secure, online access.
These shredding machines rely on robust components

MOTORS, DRIVES AND CONTROLS With high overload and low mass moment of inertia, KEB’s servo motors are an ideal solution for plastics machinery. Combined with our Combivert F6/S6/H6 drive controllers and pre-assembled encoder/ motor cables, KEB can create powerful drive systems that are precisely coordinated with each other. As well as functionality and economy, flexibility has a central role in modern drive systems. Te company’s drive controllers support the implementation of new machine concepts with extended requirements for performance, communication and integrated safety. Tey can operate different motor types across a wide power range and offer a variety of application-specific functions for plastics machinery. KEB also offers specific software solutions for plastics machinery, which can be integrated directly into the drive controller to process time- critical tasks, as well as software for the PLC.
MINIMISING DOWNTIME One of KEB’s customers, Vecoplan, designs and builds machines for shredding and processing of plastics. Tis requires drive systems that deliver top performance even in harsh conditions, as the environment is often dusty, humid and noisy. As the plastics to be recycled must be shredded, this requires machines and components that are not only efficient, but extremely robust. Vecoplan opted for KEB drive controllers, in this particular case, KEB’s Combivert F6. Te company also supplied matched mains filters and chokes to complete their system requirements.
Te selection of the machine’s individual components was guided by the objective of making the shredding machines more dynamic. Te shaft had to be able to maintain speed at all times. Even with high loads and a demanding operating environment, there could be no blockages in the shredder, as any machine downtime is costly. Very high dust loads can quickly lead to machine damage. In order to prevent this and to increase protection, the circuit boards in our drive controllers are given a special coating that ensures greater robustness and increased protection from high humidity and dust. KEB’s braking resistors are integrated directly in the drive controller, which means noticeable space savings and less wiring effort. Tis is an important factor, as Vecoplan wanted to keep the control cabinets as small as possible.
