Further, when a plurality of rows of plating tanks are provided for the pre-treatment and post-treatment tanks in the pre-treatment and post-treatment steps to form a plurality of rows of plating process lines, the pre-treatment is performed in the pre-treatment step. Products are sequentially put into one of the plating tanks in a plurality of rows of plating tanks via a product transfer device, and are simultaneously plated in multiple plating process lines, and the plated products are transferred to the product transfer device. However, if the product transfer speed of this product transfer device is slow, the loading and unloading of products to the plating process is delayed, and the products are transferred to a plurality of plating process lines at predetermined intervals. The product could not be put in, and the advantage of installing multiple rows of plating tanks could not be achieved.

For the post-processing part so that it is immersed in order Post-processing step (5) in which the rails are arranged so as to be able to move up and down, and an end portion of the pre-processing section rail (8) in the raised position and a fixed position lower than the raised position of the pre-processing section rail. The reciprocating movement is alternately performed between the starting ends of the plating processing unit rails (7) provided corresponding to the one or more rows of the plating processing tanks arranged in the reciprocating movement. A first transfer rail (10) configured to be serially aligned with the end of each of the rails to be moved, and a jig between the rails serially aligned with the first transfer rail. The jig is engaged with a locking projection (13) provided on an upper part of the jig so as to change the jig from the rail supporting the jig to the rail to which the jig is to be changed. Transfer jig transfer member (2
A first transfer device (20) provided with 1), a starting end of the post-processing unit rail (9) in the raised position, and a fixed position lower than the raised position of the post-processing unit rail. Is alternately reciprocated between each end of a plating section rail (7) provided corresponding to one or a plurality of rows of the plating tanks. A second transfer rail (11) configured to be aligned in series with each rail end is provided, and a jig is supported between the rails that are aligned in series with the second transfer rail. The jig is laterally moved between the aligned rails by locking with the locking projections (13) provided on the upper part of the jig so that the jig is changed from the rail to the rail to be changed. Second transfer jig transfer member (4
A second transfer device (40) provided with 1),
The first transfer jig transferring member (21) is provided with the first transfer rail which is selectively reciprocated between an end portion of the pretreatment section rail and each of the start ends of the plating section rail. The first transfer rail (1) is reciprocated together.
0) and a bifurcated shape capable of locking a jig that can be changed at the rail alignment position from both directions of a rail track that is changeably aligned with a locking projection provided on an upper part of the jig. A locking body (28) having a locking portion is provided,
The locking body (28) for horizontally moving the jig from the transfer source rail to the transfer destination rail along a rail track aligned with the locking projection and aligned with the rail for the pre-processing unit and the first rail. At the transfer rail alignment position, the transfer rail is moved in one direction from the transfer source pre-processing section rail to the transfer destination first transfer rail, and is moved to the alignment position between the first transfer rail and the plating processing section rail. There is a lateral movement in the opposite direction from the first transfer rail of the transfer source to the plating processing unit rail of the transfer destination in the opposite direction, and the jig is transferred to the transfer destination position of the plating processing unit rail. When the locking member of the first transfer jig transfer member is moved from the position to the position aligned with the pre-processing unit rail together with the first transfer rail, the transfer of the pre-processing unit rail is performed. Waiting supported by the standby position The second transfer jig transferring member (41) is configured to return to a position where it is engaged with the locking projection of the next jig. The second transfer rail (11) is attached to the second transfer rail (11) so as to be reciprocated together with the second transfer rail which is selectively reciprocated between the respective end portions of the component rails, and at a rail alignment position. A locking body (42) having a bifurcated locking portion capable of locking a jig to be transferred from both directions of a rail track aligned so as to be changeable with a locking projection provided on an upper portion of the jig. And the locking body (42) for horizontally moving the jig from the transfer-source rail to the transfer-destination rail along the rail track aligned with the locking projection by aligning the locking projection with the rail for the plating section. And the second transfer rail at the matching position From the rail for the transfer section to the second transfer rail of the transfer destination in one direction, and when the second transfer rail and the rail for the post-processing section are aligned with each other, The second transfer jig transfer member, which is laterally moved in the opposite direction to the post-processing unit rail at the transfer destination and in which the jig is transferred to the transfer destination position of the post-processing unit rail, is used. When the stationary body is moved from this position together with the second transfer rail to an alignment position with the plating section rail, the next stop is supported at the transfer standby position of the plating section rail and waits next. A high-speed transfer device for a product in a plating apparatus provided with one or more rows of plating tanks, wherein the apparatus is configured to be returned to a position where it is engaged with the locking projection of the second jig.
