Abstract

A copier's recirculating automatic document feeder (RADF) is assembled on a cut-out, picture-frame-type pallet. The RADF/pallet unit is then placed on a power conveyor system which accumulates these units at the location of automated test cells. Upon demand, a unit is released and conveyed by a power roller transfer unit into proper location within a test cell. At the test cell, a test fixture, including a document glass of the type contained in the copier with which the RADF will be used, is automatically raised through the pallet's central opening. All electrical, vacuum and pneumatic connections are automatically made to the RADF components by this test fixture movement. When all connections have been made, signals are sent to a personal computer to start running a test program.

Automated Recirculating Automatic Document Feeder Testing

A copier's recirculating automatic document feeder (RADF) is assembled on a cut-out, picture-frame-type pallet. The RADF/pallet unit is then placed on a power conveyor system which accumulates these units at the location of automated test cells. Upon demand, a unit is released and conveyed by a power roller transfer unit into proper location within a test cell. At the test cell, a test fixture, including a document glass of the type contained in the copier with which the RADF will be used, is automatically raised through the pallet's central opening. All electrical, vacuum and pneumatic connections are automatically made to the RADF components by this test fixture movement. When all connections have been made, signals are sent to a personal computer to start running a test program. This test program exercises the various RADF functions, and readings are taken. Upon completion of the test, the test fixture is lowered and all connections to the RADF are disconnected. RADFs passing the test program are returned to the conveyor and are sent to the next RADF manufacturing operation. RADFs failing the test are diverted to a rework station for repair.
