Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a barrel type cleaning apparatus suitable for continuously cleaning a large amount of small objects (workpieces) such as thin plate members.

[0002]

2. Description of the Related Art A cylindrical body made of a perforated plate, lath metal or wire mesh having a spiral blade on its inner surface is rotated and a cleaning liquid and / or a cleaning / drying gas is injected into the internal space of the cylindrical body. Alternatively, the whole or a part of the tubular body is immersed in a cleaning liquid, and the workpiece introduced from one end of the tubular body is washed while being fed in the tubular body in the direction of the rotation axis by the action of the spiral blade. Although a so-called barrel type cleaning device has already been put into practical use, at least in a small-sized device for cleaning small parts, those cylindrical bodies are made of a perforated plate, and the spiral blades are integrated by welding or the like. ing.

[0003]

When the work is small, the diameter of the cylindrical body may be small, but since the length of the cylindrical body is generally longer than the diameter, the cylindrical body has a small inner diameter and a long length. On the inner surface of the, forming a spiral blade spanning several continuous pitch,
The work of fixing the axial blades necessary for causing the avalanche flow of the work is performed by using a perforated plate or a thin plate in a narrow space.
It is extremely difficult because it is a three-dimensional assembly work.

Further, since the work is difficult, a gap is likely to be formed between the cylinder body, the spiral blade, and the axial blades, or an inappropriate welding bead, a protrusion such as a screw head, etc. is easily generated. There is a problem that a work, especially a small plate, is caught or caught in them. In addition, it is not easy to clean the inside of the tubular body after long-term use.

[0005]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a barrel type cleaning apparatus having a spiral blade, in which a tubular body including the spiral blade is parallel to a rotation axis. It is divided into two parts on a plane, and each divided half piece is manufactured, and a flange provided on the divided surface is used to assemble it into an integral tubular body. When assembled, it is fixed to each divided half piece of the tubular body. The spiral blades are overlapped in the vicinity of the dividing surface, and the spiral blades on the rotation direction end side are positioned on the work input port side and overlapped.

Further, if necessary, axial blades (flat blades) are provided near the ends of the spiral blades in the rotational direction.

[0007]

[Operation] Even when producing a long tubular body with a small diameter, the tubular body was divided into two parts on a plane parallel to the direction of the rotation axis.
It is easy to manufacture and fix the spiral blade on the half of the tubular body. In the divided area, the spiral vanes overlap, which inevitably creates a gap in the axial direction. However, the blade surface (workpiece exit side) side that gives the workpiece an axial propulsion force, that is, the workpiece On the side of the spiral blade surface that is mainly in contact, the gap is opened in the direction opposite to the relative movement direction of the work, so the work does not get caught in the gap.

Further, an axial blade (flat blade) is provided in front of the spiral blade extending toward the opposite half of the cylindrical body, close to the rotational end of the overlapping region of the spiral blades. For example, the work is temporarily trapped by the axial blades (flat blades), and when it jumps the axial blades, it overlaps the overlap area of the spiral blades, that is, the gap between the spiral blades at a high speed. Even with a thin plate-like work, the risk of the work getting caught in this gap can be avoided.

The pulley 7 is attached. Further, in FIG. 1, reference numeral 16 is a draining plate for preventing the cleaning agent from being mixed. Reference numeral 18 is a draining plate for preventing the cleaning agent discharged from the porous plate 2 from mixing, and 19 is a partition. Reference numeral 20 denotes a discharge port provided in the casing.

The extension 31a of the spiral blade 3a and the blade 3b
A gap D is inevitably formed in the overlap portion with
Since the work mainly moves along the blade surface on the outlet side of the work as indicated by the broken line arrow W, this gap D is opened in the direction opposite to the moving direction of the work, and the work is placed in the gap D. There is little risk of getting in. Further, the small holes 17 show a part of the small holes when the tubular body 2 is a perforated plate.
