Stacker appts. for profiled sectioned steel - has hooks and magnets for removing steel profiles from conveyor

摘要

The stacker has hooks and magnets (1) for picking up the profiles and located beneath the plane in which the profiles are being conveyed. The hooks engage the profiles from below. Mechanical sensors (3) or electronic sensors are located along the direction of conveyance and scan the space in front of the hooks along a length greater than the max. admissible distance between two adjacent profile ends. The mechanical sensors have skids (3) forced upwards by springs (6) or counterweights and projecting in the upper position over the plane of conveyance by a length greater than the max. admissible distance between adjacent profiles. The hooks or magnets are moved up and down with the skids.
