Integrated check weighing with positive control of the tubes
A compact check weighing system is developed to check tube weight on static weigh cells in between the tube filler and the cartoning machine. The system comprises channels static weigh cells for weighing all tubes produced by the tube filling machine.
Tubes are fed to the weigh cells by a servo driven pick and place unit directly from the tube filler. Following the weighing operation a separate pick and place unit picks the tubes from the static weigh cells and placed them directly onto the product chain of the cartoner.
The check weighing system is complete with a reject system for faulty tubes after check weighing.
