Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a surface treatment ball used in surface treatments such as plating and phosphoric acid treatment.

[Background of the invention]

For continuous surface treatment such as plating and phosphoric acid treatment, use a surface treatment pallet! is used. The surface treatment barrel is generally a porous container with a polygonal (usually hexagonal) cross section, and is rotatably supported by a frame. The object to be processed in the porous container is transported through the frame body to a predetermined processing tank by a transport means, and when the barrel is immersed in the processing liquid in the processing tank, the processing liquid flows into the porous container through the holes. When the barrel is rotated or rocked in this state, the object to be treated in the porous container is agitated and comes into uniform contact with the treatment liquid, so that the surface of the object to be treated is treated. After the processing, the barrel is taken out from the processing tank via the frame and transported 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 baths to automatically perform successive surface treatments. For example, in the case of galvanizing, the sequence is a pre-washing tank, a glazing tank, a washing tank, a brushing tank, and a washing tank, and the barrel is sequentially conveyed and immersed in each of the above tanks, and a series of treatments is carried out automatically. I have a desk.

[Conventional technology]

The structure of a conventional barrel is shown in FIG. In the figure,
Numerous holes (3) are formed in the container (1), and the container (1) has a polygonal cross section, and both sides (4), (
4) Lead wire insertion holes f5) and (s) are provided. An opening (6) is provided on the - side of the peripheral body (2), and a lid (7) is removably attached to the opening (6). is the locking piece f3)
, +3) is rotatably mounted around the axis f9>, f9), and the retaining piece (3), f3)
Both ends of the opening (6) are shaped so as to fit into the locking holes (A), (2), αJ, and α) provided at the front and rear of the opening (6). When loading and unloading the object to be processed into the barrel q of the above-mentioned configuration, the mirror cover (7) is manually attached and detached from the opening (6).

[The problem that the invention attempts to solve]

In the above conventional configuration, when closing the opening (6) with the lid (7), the lid (7) is fitted into the opening (6) and the locking piece (3) is closed.

Turn (3) to open the front and rear edges of the opening (6) (10, α locking hole α).

(C), C3, C13) This locking piece (S), (S)
Insert both ends of (solid line position in Figure 18) and locking piece (s
), (s) shaft (91, (9) screwed hole μ) C5, tighten the locking piece (3), r3)
to be fixed. When removing the lid (7) from the opening (6), press port A/α9. After loosening αQ, locking piece (3),
(3) to attach the locking pieces (S) and both sides of (S) to the locking holes (2), (2).

Zeng leaves C3 (dotted line position in Figure 18).

All the attachment and detachment of the lid (7) must be done by hand by the operator, and therefore, it is extremely time-consuming to take in and out the workpieces from the barre/1/a shed. This has been a major bottleneck when surface treatment is performed continuously.

[Means for solving problems]

As a means for improving the above-mentioned conventional drawbacks, the present invention provides a porous container (1) whose frame is rotatably supported by an opening (6) A at a predetermined location on the circumference of the body. ) A barrel for surface treatment, characterized in that a sliding lid (7)A is attached to the core A, and a lower cooling release mechanism is installed between the sliding lid (7)A and the porous container (1)A; The purpose of the present invention is to provide a method for automatically loading and unloading the object [F] to be treated into and out of the surface treatment barrel.

[For production]

The effects of the present invention are as follows. When the barrel filled with the object to be processed is immersed in the processing liquid, the processing liquid flows into the container through the hole and comes into contact with the object to be processed, and then the barrel is rotated or rocked to move the object to be processed into the barrel. Stir with to achieve uniform surface treatment. After processing, remove the barrel from the processing liquid and rotate the barrel in a specified direction to unlock the sliding lid.Slide the sliding lid in the opening direction to open the opening and then rotate the barrel in the opposite direction. Rotate the top and lower the opening! l
When placed in this position, the object to be processed will fall to the outside due to its own weight.

After the object to be processed is taken out from the chamber, the barrel is rotated four times in the opposite direction, and the sliding lid is slid in the closing direction to close and lock the opening.

〔Effect of the invention〕

Therefore, in the present invention, objects to be treated can be taken in and out of the barrel very simply by simply rotating the barrel, and surface treatment using the barrel can be carried out smoothly.
