However, in such an operation, there is a possibility that the plating of the portion of the plate-shaped work that comes into contact with the rack may be peeled off, or the plate-shaped work may be stained or scratched, resulting in defective products. In addition, work efficiency was poor because of manual work. Furthermore, in order to prevent the plating from peeling off, it is conceivable to provide a holding allowance for the rack on the plate-like work in advance, but this has a problem that the surface area of the plate-like work cannot be effectively used.

According to the present invention, the conveying direction of a plate-like work is continuously and automatically set, and without being held on a rack.
Another object is to provide a device that can be converted.

A flat gear 566 is fixed to one end of the second drive shaft 561, and a drive drum 552 is fixed to the other end. The spur gear 565 is opposed to the spur gear 566. When the rod 571 of the air cylinder 57 extends as shown by the solid line arrow, the spur gear 565 projects toward the spur gear 566 as shown by a two-dot chain line, and meshes with the spur gear 566. It has become.

As shown in FIG. 5, which is a partial view taken in the direction of the arrow V in FIG. 3, the drive unit 56 having the second motor M2 5
65 is provided at a position where it can mesh with the spur gear 566. On the other hand, the driving unit 5 having the third motor M3

As shown in FIG. 3, when the rod 571 of the air cylinder 57 expands as shown by a solid line arrow, the spur gear 565 and the spur gear 566 mesh with each other, and the second The rotational force of the motor M2 is transmitted through the spur gear 564, the spur gear 565, and the spur gear 566 to the second drive shaft 561.
And the second drive shaft 561 rotates. When the second drive shaft 561 rotates, the drive drum 552 rotates, and the transport belt 551 moves in the direction of the dashed arrow. As a result, the plate-shaped work 1 that has entered the gap 52 is carried on the conveyor belt 551 in the direction indicated by the arrow A, and is accommodated or received in the gap 52.

When the plate-like work 1 is accommodated in the gap 52, the rod 571 of the air cylinder 57 contracts to separate the spur gear 565 from the spur gear 566, and the second drive shaft 561 of the rotational force of the second motor M2.

As shown in FIG. 3, it rotates 90 degrees around the axis. As a result, as shown in FIG. 3, the plate unit 5 changes from a state along the transport direction A to a state along the transport direction B indicated by a dashed line.

When the plate-shaped unit 5 is in a state along the transport direction B, the rod 571 of the air cylinder 57 of the drive unit 58 (FIG. 5) is extended, and the rotational force in the direction opposite to that of the drive unit 56 is generated. The power is transmitted from the third motor M3 to the second drive shaft 561, and the transport belt 551 moves in the direction opposite to the dashed arrow (FIG. 4). As a result, the plate-like work 1 housed in the gap 52 is transported in the direction of the arrow B (FIG. 3) on the transport belt 551 in a vertical state, and is sent out to the vertical transport type plating apparatus 4. . The plate-like work 1 that has entered the vertical transport type plating apparatus 4 is plated while being transported in the B direction while maintaining the vertical state.

Since the arrangement of the vertical transport type plating apparatus 4 does not have to be connected in the same direction as the horizontal transport type plating apparatus 2, the length in one direction of the installation space of the entire plating system can be shortened. Therefore, the limitation on the length in one direction of the installation location of the plating system can be relaxed. Since it is not necessary to hold the plate-like work 1 on the rack, it is possible to prevent the plating at the portion in contact with the rack from being peeled off, thereby preventing the occurrence of a defective plate-like work. Further, it is not necessary to provide a holding allowance for the rack on the plate-like work, and the surface area of the plate-like work can be effectively used.

The tilt angle converter 9 rotates the plate unit 5 from a horizontal state to a vertical state,
This is for converting the plate-like work 1 in a horizontal state to a vertical state. However, the plate-shaped unit 5 used here has a structure in which the second drive shaft 561 is connected to the rotation shaft 533 via a horizontal rotation shaft (not shown) in FIG.
3 is driven to rotate. As a result, the plate-like work 1 conveyed in a horizontal state is
