Solutions for packaging machines
Not all packaging is alike; the complexity of the underlying technology differs depending on the type of packaging required. As a result, packaging machines require drive and automation solutions which are individually adaptable, and meet high demands in terms of resource efficiency and sustainability.
KEB’s hardware and software solutions go hand in hand here. Highly dynamic servo actuators guarantee rapid and precise positioning in packaging machines. In addition, comprehensive, modular, functional safety technology is directly integrated into the high-performance drive controllers. Scalable control technology for everything from simple PLC applications to complex MotionControl tasks also forms part of KEB’s system solution approach.
Packaging and sealing with KEB
A wide range of packaging machines can be operated with KEB Automation’s products and solutions. Individually adapted to the user’s requirements and characterised by maximum flexibility in implementation, packaging machines achieve the highest levels of efficiency with KEB.
Tubular bagging machines
The C6 Compact control system from KEB is used in tubular bagging machines which package liquids, powder or cream, for example. This control system can be flexibly adapted to the customer’s specifications and used both as a main control and as a sub-control. As an embedded control system for a complete solution, communication with the I/Os and axes takes place via EtherCAT. The C6 HMI is also used as a scalable machine display system with integrated COMBIVIS Connect Runtime for remote maintenance of the system. This makes maintenance and analysis of the tubular bagging machine very convenient for the user. Finally, drive controllers in combination with a servo motor reliably set the machine in motion.
Bagging machines
During the production of sack packaging, the items have to pass through various stations. For example, the production of cement or building material sacks includes steps such as printing, shaping the sack or securing the bottom of the sack to give it a sturdy base. KEB equips entire lines with suitable drive solutions to produce this type of packaging. To give a concrete example, KEB supplies drive controllers with a total rated power of up to 110 kW – accompanied by suitable EMC filters and power chokes. The drive controllers come in various designs and with different cooling options (a flat rear version for mounting on an external heat sink, or an air-cooled version), and are extremely flexible so that they can respond to the respective requirements of the packaging machine.

Functional safety in Pack & Food
With KEB, food processing and packaging machines can be operated in complete safety. This is true both in terms of safe movement release and where secure speed and position monitoring are concerned. Our widely differentiated package of solutions for closed-loop and sensorless safety in movement axes makes this possible. The Safe Door Lock Control also ensures that lids and covers on machines are reliably locked at all times. SDI – Safe Direction guarantees a safe direction of motion so that, for example, knives in food processing machines only move in one direction. In addition, Fail Safe over EtherCAT (FSoE) is available for transferring safety-related data. Savings can also be made in terms of wiring thanks to Profisafe, which increases efficiency, frees up space in the control cabinet and lowers costs.
DC INTERCONNECTION
Save energy while reducing the installation workload at the same time. DC interconnection makes sure of this and more, while paving the way for exchanging energy with other frequency inverters. Only one AC power supply is required for the DC coupling. KEB’s drives are freely scalable and designed for universal use. This gives the user maximum efficiency and flexibility in the actual application. An added advantage is that eliminating braking resistors reduces heat build-up and ensures less space is needed in the control cabinet.
Steel-it for motors
At KEB, servo and geared motors are available as an option with a steel-IT coating. This special epoxy coating provides particular protection against corrosion and represents real added value, especially when working in harsh environments. The steel-IT coating is resistant to salt, chemicals and high-pressure cleaners, and for users it is a reliable, readily-available alternative to stainless steel motors. The special coating meets USDA approval, which is relevant, among other things, for the food industry.
Protective coating
Harsh ambient conditions can attack the electronic components inside machines and systems, causing permanent damage. This is where the optional 3C3 protective coating (IEC/EN 60721-3-3 Class 3C2) comes into play on the printed circuit boards of our drive controllers. Adapted to the environmental demands, the coating provides protection and prevents defects and unwanted downtimes. Overall, the service life of inverters is extended – with positive impacts on the operating costs.
Sensorless control (SCL/ASCL)
ASCL (Asynchronous Sensorless Closed Loop) and SCL (Sensorless Closed Loop) are proven sensorless control methods developed by KEB Automation. They are advantageous in situations where high output speeds usually make it very difficult or even impossible to attach a sensor. Suitable for asynchronous, synchronous, reluctance, linear, spindle or torque motors, these methods ensure optimal and precise control and sensorless positioning – and are also inexpensive and easy to install. The underlying software contains coordinated virtual motor models.
Thanks to frictionally or positive connection the COMBINORM products are particularly suited for precise positioning and reliable holding.
Safe release function without residual torque and no maintenance throughout their entire service life complete the performance.
