Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a plating apparatus that stores objects to be processed in a storage case and performs surface treatment such as plating pickling in a processing liquid tank. The present invention relates to a liquid draining device that drops processing liquid remaining on the surface of a processing object.

The object to be plated, such as a cylindrical body, may have screws or uneven surfaces on its inner or outer surface, so when it is pulled out of the liquid tank and scorched, the processing liquid will be on the surface. If the treated liquid remains and is immersed in the next tank as it is, the processing liquid in the next tank becomes impure, resulting in deterioration of processing quality or a decrease in the processing liquid in the previous tank. - When a support piece is provided on the -L side of the hanger, a mounting piece is provided that protrudes from the top of the storage case that stores the object to be processed, and the mounting piece is placed on the support piece to open the storage case. A swinging cylinder is suspended from the hanger so that it can swing back and forth around the mounting piece, and the processing liquid is moved to a swinging cylinder with the tip of the cylinder rod touching the storage case that rises from the processing liquid tank as the hanger rises. When the storage case rises from the liquid tank due to the configuration in which the upper part of the tank is attached, the storage case is tilted by pushing the lower surface with a swinging cylinder and tilted so as to drain the liquid from the processed material. It is something.
