Abstract
Abstract A workpiece assembling apparatus in which a transfer table travels stepwise in a given direction. A plurality of chutes are disposed along a path at points for delivering different components therefrom to a magnetic chuck on an arm of a robot that is mounted on the transfer table. The robot is operated so that the arm picks off individual components from the corresponding chutes at each step. As the transfer table moves to the next step the robot transfers the components to a jig on an assembly station of the transfer table itself for assembly. The components are disposed for assembly in the jig and are finally assembled in fixed relationship by a driver unit on the apparatus at the end of the transfer steps of the transfer table.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
136 words
Workpiece assembling apparatus comprising, a transfer table operable stepwise in a given direction, a plurality of chutes disposed spaced from each other adjacent a path followed by said transfer table as it travels stepwise, said chutes holding different components to be assembled together into an assembly, a robot on said transfer table having a transfer arm provided with a magnetic chuck and operable to a first position for picking off individual components from said chutes sequentially as said transfer table travels successive steps for placing said transfer arm in alignment with said chutes sequentially and operable to a second position delivering the components sequentially to as assembly jig, an assembly station on said transfer table having an assembly jig receiving the components sequentially for assembly thereof, and a driver unit assembling said components into an assembly.
Claim 2
Dependent Claim
136 words
Workpiece assembling apparatus comprising, a transfer table operable stepwise in a given direction, a plurality of chutes disposed spaced from each other adjacent a path followed by said transfer table as it travels stepwise, said chutes holding different components to be assembled together into an assembly, a robot on said transfer table having a transfer arm provided with a magnetic chuck and operable to a first position for picking off individual components from said chutes sequentially as said transfer table travels successive steps for placing said transfer arm in alignment with said chutes sequentially and operable to a second position delivering the components sequentially to as assembly jig, an assembly station on said transfer table having an assembly jig receiving the components sequentially for assembly thereof, and a driver unit assembling said components into an assembly.
Claim 3
