Description

[Detailed description of the invention] [Industrial application field] The present invention is designed to carry out the process of plating a workpiece or a barrel containing it in a plating electrolytic cell, a washing tank, a recovery tank, etc. according to a predetermined treatment process in the plating process. The present invention relates to an automatic transfer device that sequentially and continuously moves up and down for immersion in each processing tank.

[Conventional technology]

In general, when a series of automatic processes such as plating is performed, the objects to be processed are usually supported on a suitable holding body such as a rack and transported sequentially along processing tanks, but they are immersed in various connected processing tanks. An elevating mechanism is used to transport the product over a partition wall. Normally, in the plating process, various processing tanks are sequentially ascended and descended to be transported, but some processed products may need to be immersed in a designated processing tank after jumping over a certain processing tank. Attempts have been made to attach a skip mechanism to a conveyor device. This is effective in that it can be configured as a production machine that can be adapted to each specific process in response to the demand for processing a wide variety of processed products with the same equipment.

[Problem that the invention attempts to solve]

Conventionally, this skip mechanism has been implemented by moving and connecting a part of the work rail to the skip work rail, and transferring and moving the rack.
The transfer means required timing and synchronous linkage, so a complex electrical control circuit and a large number of hydraulic drive devices were used, making control operation tedious and maintenance problems difficult. The mechanism itself was expensive and complicated, and was uneconomical and unsatisfactory in terms of energy conservation.

The present invention simplifies the operation control of the lifting device that can selectively process various processed products with different plating processes using the same device, and provides an economical skip device that can easily save energy and simplify the mechanism. It is intended to be provided in a suitable format.

[Means for solving the problem] The present invention consists of work rails 1, 1', 1'' installed in parallel with a skip work bar 2 that reciprocates in the longitudinal direction above the plating tank, and a skip work rail. 2', a transfer mechanism for the rack 3 supporting a holder such as a jig, and a work rail 1' including the connecting work rail 1'' are moved up and down on the plating tank 53 via the frame 5. Lift mechanism C
and a shuttle part A that connects and moves the connecting work rail 1'' to the skip work rail 2' by a hydraulic cylinder 14, which is connected to a wire mounting base 8 that moves up and down via a support 9. A rope body 7 such as a rope, wire, or chain is attached to wheel wheels 6, 6 ₁ , 6 ₂ so that it can run,
The cable body 7 is connected to the skip work bar 2, and a lever 20, which is removably connected to a locking protrusion 22 provided on the skip work bar 2, is attached to the pedestal 5 with a pin 19. This is a skip device in a plating device, which is equipped with a pivot and has a driving cylinder 21 connected to the lever 20 as a lever portion B.
