JPH08295411A - Underwater carrier conveyor supporting article carrier base - Google Patents

Abstract

PURPOSE: To prevent a conveyor chain from attachment of paint in carrying works in a painting booth. CONSTITUTION: A leg part 1A, 1B of an article carrier base is installed in a slit 3A, 3B opened at an upper part of a water tank 2A, 2B to be directly mounted on a conveyor chain 4A, 4B which endlessly circulates in the water tank 2A, 2B to form an underwater carrier conveyor. The conveyor chain is thus operated as it is immersed under water in the water tank 2A, 2B.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used as a conveyor in a painting booth in a painting process of an automobile factory.

[0002]

2. Description of the Related Art A conventional booth conveyor, for example, as disclosed in Japanese Utility Model Application Laid-Open No. 57-95277, engages a trolley with wheels with a pusher dog attached to a conveyor chain so as to move the floor surface above the floor. I was carrying it. Then, in order to prevent the paint from adhering to the conveyor chain and the pusher dog, a cover member for covering the traveling rail of the conveyor chain and a U-shaped metal fitting have been attached.

[0003]

However, since the spray paint is filled in the coating booth, the particles of the paint enter the cover member through a gap or the like into which the U-shaped bracket is inserted, and the conveyor chain. And attached to the running rail,
There is a problem that the conveyor chain and the traveling rail must be cleaned as needed to remove the adhered paint.

[0004]

Therefore, according to the present invention, a water tank having a slit in the conveying direction for loading a leg portion of an article carrier is opened in the upper portion along the conveying direction, and endless circulation is performed in the water tank. The above-mentioned problems of the prior art are solved by submerging a conveyor chain on which the article carrier is mounted and a travel guide rail that supports the conveyor side of the conveyor chain under water.

[0005]

The leg portion of the article carrier is placed on the article carrier table conveyor chain which is inserted from the slit of the water tank and circulates endlessly in the water tank, and is guided and conveyed along the slit together with the conveyor chain. Since the conveyor side of the conveyor chain is placed and supported by the traveling guide rail,
The carrier is supported and transported without being bent downward due to the weight of the transported article and the carrier. The paint particles scattered in the coating booth do not directly adhere to the conveyor chain even if they fall into the water tank.

[0006]

1 is a front view of the present invention in a coating booth, and FIG. 2 is a side sectional view of FIG. The legs 1A and 1B of the article carrier 1 on which the article B such as a vehicle body is placed are respectively provided in slits 3A and 3B opened at the upper portions of a pair of left and right water tanks 2A and 2B which are arranged side by side in the carrying direction and are arranged in parallel. The conveyor chains 4A and 4B, which are loaded and endlessly circulated, are supported and conveyed on the conveying side. It should be noted that the water tanks do not necessarily have to be a pair of right and left, but may be one wide water tank.

The conveyor chains 4A and 4B are driven by the drive device shown in FIG. 3, and traveling guide rails 5A, 5B and 6A, respectively are provided on the transport side and the return side of the chain.
6B is provided.

The drive device shown in FIG. 3 has an output shaft 7 driven by a motor M which has a sprocket S which is inserted into bearings in water tanks 2A and 2B and meshes with conveyor chains 4A and 4B. A water seal member 8 is attached to the hole.

The water in the water tanks 2A and 2B is supplied from water supply ports 9A and 9B provided in the upper part of the water tanks, and foreign matter removing plates (not shown) are provided to the drainage ports so that the drainage ports are not clogged by suspended matter as needed. No.) is provided, but the foreign matter removing plate is not necessary when drainage is performed by overflow.

Further, the paint shelter covers 10A and 10B shown in FIG. 1 are detachably attached to both sides of the article carrier 1, and are attached at the paint booth entrance and removed at the exit. Not returned on the return line to the entrance side.

[0011]

According to the present invention, since the conveyor chain which conveys the article carrier is operated by being submerged in the water tank, it is blocked from the spray paint particles scattered in the booth to prevent the paint from adhering. Cleaning for removing paint on the conveyor chain is not required, which saves labor in maintenance work.Also, since the legs of the article carrier are directly mounted on the conveyor chain, the timing of mounting can be set freely. Because it is possible, unlike the push-pull transport by the conventional pusher dog,
It is possible to select the loading timing of the article carrier on the conveyor chain so that it will be optimally conveyed according to changes in production volume and coating color, and to prevent pulsation of the carrier that occurs when the pusher dog is engaged. Have.
