The system is used for the automatic removal of plaster casts (100 boxes) as well as for control and labeling of casts during the procedure. Finally, the casts are fed into a packaging machine of the customer.
The system operator cuts the adhesive tape on the cover tabs, opens them and removes the cover cardboard. After this they transfer the cartons to the infeed conveyor over a roller table. The cartons are fed to the system individually, and then two opened cartons are moved into the removal position. This prevents the end flaps and the longitudinal tabs from falling back into the starting position during the extraction, via guideways and binders respectively.
Portal handling, with an integrated 8x suction gripper, shall remove the cast (in layers) from two cartons at once, and position the casts on a conveyor belt. The two separating crosses, as well as the middle and the lower cardboard liner, are also removed from the cartons during the portal handling and dropped onto a conveyor belt. On the conveyor belt, the casts head through a camera station, in order to check the printed product number on their bottom, using an OCV system. There is a provided station for the manual insertion of casts. As part of the same, monitoring of the correct number of plasters is done on a belt weighing station - this is determined by the total weight of the respective cast.
A labelling machine installed on the conveyor belt, with an integrated thermal transfer printer, then prints the MHD date and the batch number on self-adhesive labels and locates them on the casts. The quality of the thermal transfer printing shall be checked using a camera system before the labels are applied. In addition, the pharmacy barcode will be read out on the labels using optosensorics and monitored. The system will stop as soon as a label has been identified as faulty. The correct position of the applied labels shall be checked using a downstream camera system located behind the labelling machine. Finally, the casts shall be turned 90° (from transverse transportation to longitudinal transportation) and transferred to the infeed conveyor of the customer's packaging system in a chicane.
N.i.O.-checked casts are pushed off the belt directly behind the respective test station and directed in separate plastic crates. Two emptied cartons at a time are advanced from the removal station and transferred to the return belt by means of an angle transfer. The discharge of n.i.O. cartons (number or packing sample of casts not correct) in the conveying direction is also provided. (Loss of cycle time) The emptied cartons are opened, and folded back to a flat cut, on the floor in a separately housed station at the end of the dsicharge conveyor. The flat cuts are provided in a magazine (standing), collected for manual inspection.
