End of Line Confectionary Packaging Machine

Posted in Food and Beverage, HMI and SCADA, Manufacturing Automation and Intelligence, Packaging Machinery Programming


DMC implemented a high speed motion control application that controls the process of packaging confectionary products into their final outermost wrapper. The application controls a machine employing five servo axes, four linear motors, six analog PID-controlled heating elements, and a sensor-based registration system.


The control PLC program in combination with the ELAU motion control program form a complete solution for controlling the wrapping machine. Stacks of product enter the machine on a servo-controlled infeed conveyor which changes speed based on the detected rate of input product. Linear motors then push the products one at a time through a cam-driven wrapping drum. Film is dropped down from a geared draw roll servo and cut by an intelligent registration-adjusted slicing axis. Then the package is pushed onto a heated conveyor which seals the film around the product as it exits the machine.

Customer Benefits

  • Enables faster production with an output of up to 50% faster than previous machine
  • Reduces machine setup time with fast-acting automatic registration system.
  • Vastly reduces time spent pinpointing hardware problems through intuitive Human Machine Interface (HMI).
  • Complete configuration options on HMI improve future expandability by allowing multiple products to run on same production line with no software change
