Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a barrel container used for cleaning and drying industrially produced parts.

[0002]

2. Description of the Related Art As a conventional technique, a part to be processed is put in a barrel container made of a metal plate such as stainless steel having a large number of holes and washed or dried.

[0003]

In order to smoothly perform cleaning and drying, the barrel container is rotated so as to stir the parts to be treated in the barrel container, and the treatment is performed.

When the barrel container has a cylindrical shape, even if the container is rotated for stirring, the parts to be treated slip therein and satisfactory stirring cannot be performed. Although the barrel container may have a polygonal tubular shape in consideration of stirring efficiency, if the component to be processed has a small flat plate shape, the component to be processed may adhere to the inner wall surface of the container. In some cases, the cleaning or drying could not be performed sufficiently, and a processing failure might occur.

Therefore, an object of the present invention is to prevent parts from sticking to the inner wall of the container in a barrel container used for cleaning / drying and the like, and prevent defective cleaning and defective drying.

[0006]

In order to achieve the above object, according to the present invention, in a hollow cylindrical barrel container that is rotationally driven in a horizontal position, the wall surface of the barrel container allows the component to be treated to pass through. Impossible holes are provided and a large number of small projections are formed on the inner peripheral surface of the barrel container.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to the preferred embodiments shown in the accompanying drawings.

The barrel container 1 shown in FIG. 1 is used for cleaning and drying the parts P, and in this embodiment,
A circular cylindrical member made of stainless steel having high chemical resistance is used, and a number of holes 3 are formed in the peripheral wall 2. The barrel container 1 is rotatably supported in a horizontal posture by a pair of support plates 4 and 5, and is rotatably driven in one direction via gears 6 and 7 driven by a motor (not shown). There is. An opening / closing lid (not shown) is provided on a part of the barrel container 1, and the component P can be put into and taken out of the barrel container 1 from the opening / closing lid.

The hole 3 of the barrel container 1 has a part P inserted therein.
Needless to say, it is formed in such a size that it does not fall out. A small hemispherical small projection 8 is formed on the inner surface of the peripheral wall 2 of the barrel container 1. The small projections P are formed at substantially the same pitch as the holes 3 in this embodiment, but the pitch and height are determined in consideration of the size and shape of the component P. In this example,
The minimum distance D between the adjacent holes 3 is smaller than the minimum width W of the component P. By doing so, at least one of the small projections 8 faces the plane of the component P, and the component P does not come into close contact with the inner surface of the barrel container 1.

Next, the operation will be described. The barrel container 1 accommodating the part P is put into a washing tank (not shown) while being hung by the support plates 4 and 5, and is rotationally driven. At this time, the cleaning liquid in the cleaning tank enters the barrel container 1 through the hole 3 and the inside part P is immersed in the cleaning liquid,
In this state, the barrel container 1 is rotationally driven to stir and wash the component P. Since the small protrusions are formed on the inner surface of the barrel container 1, the stirring operation is promoted even when the component P has a small shape, and the component P may be closely attached to the inner surface of the barrel container 1. Absent. For this reason, the required cleaning is reliably performed for all the accommodated parts P, and cleaning failure does not occur.

When this cleaning is completed, the barrel container 1 is pulled out from the cleaning tank and is sent to the next drying step together with the barrel container 1 without taking out the parts P. In this drying step, the barrel container 1 is rotationally driven in the warm air blown out from a well-known blower device. The warm air enters the barrel container 1 through the hole 3 and the component P in the barrel container 1 is dried while being stirred by the rotation of the barrel container 1. During this drying operation as well, as mentioned above, the inner surface of the barrel container 1 is surely agitated without coming into close contact. For this reason, all the parts P are dried cleanly, so that no defective drying occurs.

After completion of this drying, the part P is taken out of the barrel container 1 and carried to the next step.

[0013]

Other Embodiments The above embodiment is an example in which the barrel container 1 is applied to a circular tubular shape, but as shown in FIG. 2, it is originally a hexagonal or octagonal with some degree of stirring ability. It is also possible to carry out in the polygonal barrel-shaped barrel container 11. This barrel container 11 also has a large number of holes 13 in its peripheral wall 12.
Needless to say, a small protrusion (not shown) is provided on the inner surface of the peripheral wall 12.

When the barrel container 1 is made of metal such as stainless steel, a dent may occur during stirring depending on the material of the part P, but such inconvenience can be solved by the following changes. You can That is, in the embodiment shown in FIG. 3, the metal barrel container 21 (peripheral wall 2
By implanting a small protrusion 28 made of synthetic rubber such as silicone rubber or synthetic resin such as polyethylene in 2),
Prevents the formation of dents. The relationship between the small protrusions 28 and the holes 23 with respect to the parts is substantially the same as that of the first embodiment described above. In addition to this, even if the barrel container itself is made of a synthetic resin, the effect of preventing the occurrence of dents can be obtained.

However, when the small protrusions and the barrel container are made of synthetic resin, the following points must be noted. That is, there is no particular problem in the case of water-based cleaning such as pure water, but when cleaning and drying using an organic solvent such as alcohol or triethane as a cleaning liquid, small protrusions or It is necessary to determine the type of synthetic resin used for the barrel container.

[0016]

According to the structure of the present invention, since the small protrusions are formed on the inner peripheral surface of the barrel container, it is possible to prevent the parts to be treated from adhering to the inner wall of the container during the cleaning / drying process. Since the stirring operation can be promoted, high-quality cleaning / drying can be achieved without causing poor cleaning or poor drying without using CFC as the cleaning liquid. In addition, it is possible to perform from the washing to the drying of the parts in a series of flow steps, the washing / drying efficiency is significantly improved as compared with the conventional one, and the cost reduction can be achieved.
