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 during operation, a distinction must be made between humans and objects. Horizontal safety light curtains with reduced resolution do not detect the pallet feet when retracting and extending, so the machine remains in operation. The palletizer is only deactivated when a worker interrupts the defined number of beams via an access. A second light curtain secures the area vertically so that no employee on a pallet enters the danger zone.
