In FIG. 1, reference numeral 1 denotes a separation supply device,
Multiply-stacked sheet-like transported objects 2 (for example, CD cases)
Conveyor 4 (transporting means) that transports diagonally upward
And an advancing / retreating means 6 for separating the sheet-like conveyed articles 2 one by one. The sheet-like conveyed material 2 is aligned upright with the belt conveyor 4 in a state of being slightly inclined backward in the traveling direction. Such a rearwardly inclined alignment state is maintained by the conveyed article support 8 moving integrally with the conveyor belt 4a.

The conveyed object support 8 is provided on the conveyor belt 4.
a and a backrest portion 8b slightly inclined backward from the vertical direction with respect to the conveyor belt 4a.
And a connecting portion 8c connecting the two, and transports a series of thin plate-like conveyed objects 2 while supporting them on the backrest 8b of the conveyed object support 8. Then, even if the base portion 8a is located at the end of the conveyor belt 4a, the connecting portion 8 is provided so that the last thin sheet-like conveyed material 2 can reach the tip of the fixed conveyance auxiliary plate 10.
The length of c is set.

Although the sheet-like conveyed object 2 has the same shape in the drawing, objects of various sizes such as CD and DVD storage media are mixed, and after being conveyed by the belt conveyer 4, the reciprocating means 6 Are separated and sorted by

The reciprocating means 6 is a piston-cylinder mechanism comprising a piston 6a as a pushing portion and a cylinder 6b as a driving portion. The piston 6a is controlled to reciprocate in response to the fluid pressure supplied to the cylinder 6b. . Since the supply and discharge of the fluid pressure are performed in conjunction with the moving speed or the intermittent moving speed of the belt conveyor 4, the separation operation can be performed at a considerably high speed.

As described above, since the sheet-like conveyed article 2 is conveyed in a slightly backwardly inclined state, the lower end of the sheet-like conveyed article 2 is separated from the lower end of the adjacent sheet-shaped conveyed article by the step space 2a.
