Access Control on Palletizing Systems with Safety Light Curtains with Reduced Resolution

In intralogistics centers, empty wooden pallets are loaded fully automatically at palletizing stations. In order to provide workers with safe access to these zones during operation, a distinction must be made between humans and objects. Horizontal safety light curtains with reduced resolution are installed on the side of the conveyor. The pallet feet are not detected during extension and retraction due to the reduced resolution, the system remains in operation. Only when a worker interrupts the defined number of beams by accessing the area is the palletizer switched off.
