Abstract

PURPOSE:To permit fully continuous and automatic operation of a surface treatment to be used for a barrel by fitting a cover plate pivotally to one edge of the aperture of a perforated vessel, opening the cover plate fully by a detaining means and providing a cover plate unlocking mechanism between the cover plate and the perforated vessel. CONSTITUTION:The cover plate 7A is unlocked by the cover plate unlocking mechanism and the perforated vessel 1A is rotated, then the cover plate 7A opens automatically by its own weight when the aperture 6A is positioned on the lower side. The cover plate 7A is pivotally fitted to the rear edge 11A of the aperture 6A so that the cover plate is opened to the prescribed angle by the detaining means when the cover plate is fully opened. The vessel 1A rotates further to move the aperture 6A to the upper side. Works are charged into the vessel 1A just prior to the closing of the cover plate 7A and the cover plate is locked by the detaining means. The works are subjected to the surface treatment such as plating when the vessel 1A is immersed into a treating liquid in this state. Automatic charging of works into and out of the vessel is permitted by the above-mentioned method, by which the fully continuous and automatic operation of the surface treatment is attained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a surface treatment barrel used for surface treatments such as plating and phosphate treatment.

[Background of the invention]

A surface treatment barrel is used to continuously perform surface treatments such as plating and phosphate treatment. The surface treatment barrel is generally a porous container with a polygonal cross section (usually hexagonal shape), and the object to be treated is placed in the porous container and is rotatably supported by a frame. When the barrel is immersed in the processing liquid in the processing tank, the processing liquid flows into the porous container through the holes, and when the barrel is rotated or rocked in this state, the porous The object to be treated f'i in the container is stirred and brought into uniform contact with the processing solution, and in the case of plating, when electricity is applied to the object to be treated in the barrel as a cathode, plating or other surface treatment is applied to the surface of the object to be treated. administered. After processing, the barrel is taken out from the processing tank by means of a conveying means via the frame, and further transferred to the next predetermined processing tank for the next processing.

The surface treatment barrel is thus extremely useful because it is successively conveyed to a series of treatment tanks to automatically carry out water supply and surface treatment. For example, in the case of galvanizing, a pre-cleaning tank, a degreasing tank, a washing tank, a plating tank, and a washing tank are arranged, and the barrel is sequentially transferred and immersed in each of the tanks, and a series of treatments is automatically performed.

[Conventional technology]

The structure of a conventional barrel is shown in FIG. In the figure, (

It is a trap to fit into the locking holes σ3, C13, C131, and C13 provided in Qυ. When the object to be processed is taken in and out of the barrel αa having the above structure, the lid (7) is attached to and removed from the opening (6).

[Problem that the invention seeks to solve]

In the above conventional configuration, when closing the opening (6) with the lid (7), the lid (7) is fitted into the opening 8 (6), and the locking piece (

U and α are released from prisoner (Figure 18, dotted line position).

All the attachment and detachment of such lids (with force) must be done manually by workers, and therefore, it is extremely time-consuming to take in and out the objects to be treated from the barrel I.Continuous surface treatment using one surface treatment barrel This was a major bottleneck in fully automation.For example, in the case of metsuki, at the end of the process, the barrel or workpiece is taken out for post-processing and drying, but at this time, the barrel must be opened and closed, and the workpiece taken out. This had to be done manually, making it impossible to completely automate the continuous plating process.

[Effect]

The operation of the present invention is as follows.

4 plate lock - When the lid plate is unlocked by the release mechanism and the porous container is rotated, the lid will open naturally due to its own weight when the opening is located at the bottom, and the opening will open all the way to the top in the open state. The lid moves and becomes vertical/'After IT, the lid closes naturally due to its own weight.

Therefore, the opening moves from the upper side 1, and just before the cap closes, the rotation of the barrel is temporarily stopped, the material to be processed is put into the barrel, the barrel starts rotating again, and when the lid closes, the lid plate locking mechanism Lock the cover plate.

When the barrel is immersed in the processing liquid in this state, the processing liquid flows into the container through the hole and comes into contact with the object to be processed. When the barrel is rotated or rocked, the object to be treated is stirred within the barrel and uniformly comes into contact with the treatment liquid to undergo surface treatment such as plating. After processing, the barrel is removed from the processing solution, the lock-release mechanism is used to unlock the lid plate, and the barrel is rotated. When the opening is located on the lower side, the lid automatically opens under its own weight to release the processed material inside the barrel. The object falls to the outside from the opening due to its own weight and is received in a predetermined receiving means.

〔Effect of the invention〕

Therefore, in the present invention, the objects to be treated can be automatically taken in and out of the barrel, and complete continuous automation of surface treatment using the barrel can be realized.
