Next, the action will be explained.

It is assumed that the papers P to be transferred are stacked in front of the left end of the bed 1 and are transferred to the right along the bed 1. The positions of the left and right paper holding devices 22A, 22B and the position of the back and forth moving head 19 are set in advance according to the size of the paper. The operations of each section to be described below proceed automatically according to a preset program of the sequence controller.

When the elevator platform 9 of the tower 2 descends and the sensor 36 detects the top surface of the stacked papers and the elevator platform 9 stops, the height of the paper partitioning device 27 is adjusted to match the upper layer to be conveyed and the remaining paper. Located at the border.

First, the first partition member 28 penetrates between the sheets of paper. Subsequently, the second partition members 29A and 29B penetrate into the gap formed by the penetration of the first partition member, and extruded combs 30 and 30 integral with the second partition member are inserted.
pushes the upper layer of paper forward by several centimeters. This state is shown by the chain line in FIG. In parallel with the second partition member and pusher comb pushing out the upper layer of paper, the first partition member 28 is lowered slightly to widen the gap.
Next, the rotating arms 26A and 26B are rotated and inserted into the enlarged gap in order from their tips, and when the entire arms are inserted, they stop to support both left and right sides of the paper. In parallel with this rotation of the rotating arm, the left and right ends of the protruding side of the extruded upper layer are held by the left and right paper holding devices 22A, 22B, and then the feed screw 2
