WIPO Patent Application WO/1988/006945
Kind Code:
A1
Abstract:
This invention relates to a pallet changer. A conventional pallet changer takes a long pallet transfer time and is low in work replacing efficiency. This invention has been developed so as to eliminate these drawbacks. A pallet changer (2) has a work station (20) and a robot (100). A plurality of pallets (PL) are arranged on the work station (20). Each pallet (PL) has a work thereon. The robot (100) has retainers (a first arm (160) and a second arm (161) in the embodiment). These retainers are used to detachably retain a pallet (PL). According to the present invention, the retainers are moved in parallel with a second direction (U2) in which the pallets (PL) are arranged, and they can be set to the positions of any pallet (PL). The retainers are moved to a place where they are opposed to a desired work and its pallet, and positioned properly. The retainers then hold the desired pallet (PL) and carry it from the work station (20).
