ABSTRACT:
A device for removing a plurality of ferromagnetic, stacked or dumped, workpieces from a container incorporates a switchable magnetic holder which can be moved up and down by means of a hoisting apparatus and, moreover, can be shifted in an approximately horizontal plane and positioned over the said container and a conveyor respectively. The magnetic holder takes the form of a magnet carrier plate mounting a plurality of holding magnets of which at least one is an a.c. magnet. Means are provided for gradually reducing the excitation of the holding magnet while the material handled is being dropped. What is achieved by these means for gradually reducing the excitation of the holding magnet while the workpieces handled are being dropped or deposited is that these are left in a non-magnetic state after their separation from the magnet carrier plate, thereby avoiding problems in subsequent plant operation or later processing thanks to the removal of residual magnetism without the need for any additional demagnetizing means.
