Description

[Detailed explanation of the idea] "Industrial application field" The present invention relates to a barrel for metsuki.

``Prior art'' and ``Problems to be solved by the invention'' Generally, the barrel for plating used in the barrel plating method has a basket-shaped main body in the shape of a polygonal hollow column, and a large number of products are housed in the barrel. By placing the barrel in the plating tank and rotating the barrel by appropriate means, the products in the barrel can be plated at the same time.

However, in conventional barrels, the peripheral wall of the main body was made of a perforated plate or mesh material made of chemical-resistant material, so the aperture ratio was small (approximately
70% or less), the diffusion or electrophoretic movement of metal ions in the plating solution into the barrel is inevitably hindered, resulting in a long plating process, poor plating efficiency, and poor plating efficiency. Ta.

In addition, because the opening ratio is small, the plating solution does not drain easily, and a large amount of plating solution remains in the barrel and is carried into the post-processing cleaning process, so a large amount of washing water is required for cleaning the plating solution. Difficulties such as excessive heat and long cleaning times were pointed out.

"Means for Solving the Problem" In view of the above-mentioned circumstances, the present invention was made to solve the above-mentioned conventional problems, and the peripheral wall of the main body in the shape of a polygonal hollow column is made of plastic or the like. A plating barrel made of a perforated plate made of a chemical-resistant material, a mesh material, or other flowable material, a part of which can be opened and closed, and a plating barrel configured to be rotatably supported in a plating tank. In the device, the peripheral wall portion of the main body portion having the opening/closing portion is made of a honeycomb core formed with chemical resistance.

"Operation" Since the present invention consists of the above-mentioned means, it functions as follows. In other words, the peripheral wall portion having the opening/closing portion of the polygonal hollow columnar barrel body has an open area ratio of 95 to 99%.
Since it is formed of a large honeycomb core, metal ions in the plating solution can easily move into the barrel by diffusion, electrophoresis, etc., and therefore plating work can be performed efficiently. In addition, since the plating solution drains easily and the amount remaining in the barrel is small, it is possible to reduce the amount of plating solution carried into the post-processing cleaning process, thereby reducing the amount of cleaning water used and It is possible to improve the efficiency of cleaning work.

"Embodiment" The present invention will be described below based on an embodiment shown in the drawings.

In FIGS. 1 to 4, 1 is a plating tank, and a predetermined amount of plating liquid 2 is stored in this plating tank 1. As shown in FIG. Reference numeral 3 denotes a plating device detachably installed in the plating tank 1, and the plating device 3 is constructed as follows. That is, 4 is a frame, and this frame 4 includes a horizontal frame member 4a,
It consists of a pair of vertical frame members 4b, 4b, each hanging down from both ends of a horizontal frame member 4a, and a motor 5 is fixed to the lower surface of one end of the horizontal frame member 4a via a mounting member. A drive gear 6 is fitted to the tip of the motor shaft 5a of the motor 5. 7 is a barrel, and this barrel 7 is constructed as follows. That is, 8 is the main body of the barrel 7, and 9 is the peripheral wall of the main body 8, and the peripheral wall 9 is made of a chemical-resistant material to a size that forms each surface of a substantially regular polygon. Honeycomb core wall plates 10, 10... of an appropriate cell size are connected in a regular polygonal shape via a joining member 11, and one surface is opened to form an opening/closing part in a part of the peripheral wall part 9. In order to open and close the opening 12, one end thereof is screwed to the joining member 11 located at one side end of the opening 12 via a hinge 13 so as to be openable and closable. , formed of a chemical-resistant material and arranged to maintain the closed state by a hooking member 14 provided between the other side end and the joining member 11 located at the other side end of the opening 12. A honeycomb core lid body 15 of an appropriate cell size is provided, and this lid body 15
and wall plates 10, 1 connected by a joining member 11.
0..., the peripheral wall portion 9 is formed in a regular polygonal shape (regular octagonal shape in the embodiment). One side end of this peripheral wall portion 9 is closed by an end face plate 16, and the other side end is in a positional relationship that meshes with the drive gear 6 at a position below the drive gear 6. The main body part 8 is constituted by a toothed part 18a that meshes with an intermediate gear 17 that is pivotally supported by a barrel driving plate 18 provided on the outer peripheral part of the toothed part 18a. A mounting shaft 19 having a through hole 20 is provided protruding from the center of the end plate 16 and the barrel drive plate 18 of the main body portion 8, respectively. The barrel 7 has both mounting shafts 19, 19 pivotally supported in shaft holes provided in both vertical frame members 4b, 4b in order to maintain a positional relationship in which the toothed portion 18a of the barrel drive plate 18 meshes with the intermediate gear 17,
The barrel 7 is mounted between the vertical frame members 4b, 4b so as to be rotated by the rotation of the motor 5 via the intermediate gear 17.

Reference numerals 21 and 21 denote a pair of brackets provided at predetermined positions in the outer central portions of both the vertical frame members 4b and 4b, and these brackets 21 and 21 are connected to support members protruding from the upper end of the plating tank 1. 22, 22
The brackets 21 and 21 are respectively placed on top of the barrel 7, and the plating device 3 is engaged with the plating tank 1 by appropriate attachment/detachment means (not shown).
The plating liquid 2 is immersed in a predetermined amount in a positional relationship.

In addition, 23 is an anode inserted at a predetermined position in the plating tank 1, and 24, 24 are mounting shafts 19, 19.
The cathode is inserted into the main body part 8 of the barrel 7 through the through holes 20, 20 of the main body part 8 of the barrel 7.

Since the plating barrel according to the present invention has the above-mentioned configuration, the metal ions in the plating solution can easily move into the barrel through diffusion and electrophoresis, and the plating solution can drain easily when transferred to the next process. It is.

Regarding the barrel action of the present invention, we have mainly explained the plating process and the post-processing cleaning process. If the work is carried out continuously using work equipment, it can be used not only for the plating process and the post-processing cleaning process, but also for example, the water washing and degreasing process in the pre-processing because the liquid in the barrel drains well. , the work efficiency of other processes can also be improved.

"Effects of the Invention" As detailed above, according to the barrel for plating according to the present invention, the peripheral wall of the barrel body is formed of a honeycomb core with a large aperture ratio of 95 to 99%. Metal ions in the plating liquid can easily move into the barrel due to diffusion, electrophoresis, etc.
Therefore, it is possible to improve the work efficiency of plating work, and since the plating liquid drains well and the amount remaining in the barrel is small, the amount of plating liquid carried into the post-processing cleaning process is reduced. As a result, excellent effects can be achieved, such as reducing the amount of washing water and making it possible to improve the efficiency of washing operations.
