PURPOSE: To make both operations for material feed and empty pallet discharge into automation, by loading a sheet material on a pallet and conveying it with a feed conveyor, then constituting it so as to be delivered to an empty pallet discharge conveyor running in an orthogonal direction.

CONSTITUTION: A pallet 11 loading a sheet material W is transferred onto a feed conveyor 20 via a turntable 40 and transferred in a white arrow direction. And, when the pallet 11 arrives at a carry-out end 20b, a tip of the sheet material W is held by hand and fed to a sandwich conveyor (unillustrated herein) in a manual manner. With this operation, the material W on the pallet 11 is delivered to the next process. And, the empty pallet 11 is lifted up by a lifting cylinder (unillustrated herein) with operation of a detector, and transferred to a roller conveyor 33, then discharged by a discharge conveyor 30. With this constitution, material feed and empty pallet discharge both can be automated.
