Next, the extruding mechanism 15C is activated, and the transport unit 12C is moved in the reverse B direction, resulting in the state shown in FIG. At this time, since the drive shaft 143 of the transport unit 12C moves along the guide groove 111, the drive unit 14 rotates and the roller group 142 is in a state along the A direction. Next, the extruding mechanism 15D is activated, and the transport unit 12D is moved in the A direction, resulting in the state shown in FIG. At this time, the drive shaft 143 of the transport unit 12D moves along the guide groove 111, but the drive unit 14 does not rotate. Then, the same operation as described above is repeated.
[0088]
As a result, the plate-like workpiece 1 that has been conveyed in the vertical state is successively transferred by the conveyance units 12A to 12C after the conveyance direction is changed by 90 degrees from the A direction to the B direction, and then sent in the vertical state.
[0089]
