A pick-off device for an automatic stacker useful in stacking laminations for electric machines in which the number of laminations required to form a stack is picked off by means of a head from an orderly supply of laminations stored in a magazine. The pick-off head can be tilted so that the picked-off lamination stack can be fed to a further processing station. In order to prevent individual laminations from dropping out when they are being picked off and to make it possible to vary the number of laminations picked-off, the laminations are arranged in the magazine on a horizontal carrier which is lined up with a take-up mandrel of the pick-up head, being aligned on the carrier by a guide bar connected to it. The take-up mandrel has a pick-off finger which fits into a cutout in the laminations and can be lifted relative to the carrier alone or together with the take-up mandrel to pick off the laminations. The lifting of the finger or mandrel is triggered by a device for measuring the size of the lamination stack. When the lamination stack, pushed onto the take-up mandrel, has been separated from the laminations on the carrier, the lamination stack is axially retained on the take-up mandrel by controlled holding elements. |
