Device and method for unstacking plate-shaped parts

摘要

In a device for unstacking plate-shaped parts (12), in particular sheet metal blanks, comprising at least one supply station (13) in which at least one stack (14) of plate-shaped parts (12) is located and at least one conveyor station (15) on which the plate-shaped parts (12) are transported further in an unstacked manner, an unstacking unit (17) being provided for transferring the plate-shaped parts (12) between the supply station (13) and the conveyor station (15), said unstacking unit engaging the stack of parts (14) and removing individual plate-shaped parts (12) while unstacking the stack of parts (14) and depositing them in the conveyor station (15), the unstacking unit (17) comprises two robots (18a, 18b) working independently of each other, which alternately engage a common stack of parts (14) of the supply station (13) and are controlled by a control unit (19) in such a way that a first or a second robot (18a, 18b) removes a plate-shaped part (12) from the stack of parts (14) while the first robot (18a, 18b) simultaneously deposits a picked-up plate-shaped part at the conveyor station (15).

主权项

1. A device for unstacking plate-shaped parts, the device comprising:
at least one supply station in which at least one stack of plate-shaped parts is located, at least one conveyor station on which the plate-shaped parts are transported further in an unstacked manner, a gantry-type supporting device which bridges the at least one conveyor station, a linear guide device comprising two rail modules mounted at the supporting device which bridge the at least one conveyor station perpendicular to the at least one conveyor station, an unstacking unit to transfer the plate-shaped parts between the at least one supply station and the at least one conveyor station, said unstacking unit engaging the stack of parts and removing individual plate-shaped parts while unstacking the stack of parts and depositing the unstacked parts in the at least one conveyor station, wherein the unstacking unit comprises two robots designed as multiaxial robots with at least four pivoting axes and each having a rail module, of which a first vertical pivoting axis allows a swiveling motion between the supply station and the conveyor station, each of said robots being mounted in a suspended manner and linearly guided at the rail modules, each of said two robots being suspended from a supporting device and working independently of each other, which alternately engage at least one common stack of parts of the at least one supply station; the device further comprising a control unit configured to control the two robots such that one of the two robots removes at least one plate-shaped part from the common stack of parts while another of the two robots simultaneously deposits at least one picked-up plate-shaped part at the at least one conveyor station.
