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 in an automobile factory.

[0002]

2. Description of the Related Art A conventional booth conveyor is disclosed in, for example, Japanese Utility Model Laid-Open Publication No. 57-95277, in which a bogie with wheels is engaged with a pusher dog attached to a conveyor chain, and the booth is conveyed on the floor. Had been transported. Then, in order to prevent the paint from adhering to the conveyor chain and the pusher dog, a cover member and a U-shaped metal fitting which cover the running rail of the conveyor chain are attached.

[0003]

However, since the paint booth is filled with the paint in the form of spray, the paint particles enter the cover member through a gap or the like where the U-shaped bracket is inserted, and the conveyor chain. And adheres to the running rail,
There has been a problem that the conveyor chain and the running rail must be cleaned at any time to remove the adhering paint.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a water tank having a slit in the conveying direction in which a leg of an article conveying table is inserted at an upper portion thereof, extending in the conveying direction, and performing endless circulation in the water tank.
Conveyor that places and transports the legs of the article carrier
By providing the submerged travel guide rails for supporting the conveying side of the over emissions and the conveyor chain, is obtained by solving the problems of the prior art.

[0005]

The leg of the article carrier is inserted through a slit in a water tank and placed on a conveyor chain that circulates endlessly in the water tank, and is guided and conveyed along the slit together with the conveyor chain. transport side of the chain is traveling guide Les
Because it is supported by Lumpur, transporting goods and articles
The article carrier can be moved without bending downward due to the weight of the carrier.
Support and transport the article carrier . And, even if the paint particles scattered in the paint booth fall into the water tank, they do not directly adhere to the conveyor chain.

[0006]

1 is a front view of the present invention in a painting booth, and FIG. 2 is a sectional side 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 arranged in parallel in the conveying direction. The loaded and endlessly circulating conveyor chains 4A and 4B are supported and transported on the transport side. In addition, the water tank does not necessarily have to be a pair of left and right, and may be one wide water tank.

[0007] The conveyor chains 4A, 4B are driven by a drive device shown in Fig. 3, and traveling guide rails 5A, 5B and 6A, 6A,
6B are provided.

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

The water in the water tanks 2A, 2B is supplied from water supply ports 9A, 9B provided in the upper parts of the water tanks, and the water discharge ports are provided at the water discharge ports as necessary so that the water discharge ports are not blocked by floating substances (not shown). However, a foreign substance removing plate is not required when drainage is performed by overflow.

On both sides of the article carrier 1, paint-removing covers 10A and 10B shown in FIG. 1 are detachably mounted, attached at the entrance of the painting booth, removed at the exit, and the removed covers 10A and 10B are shown in the figure. Not returned to the entrance side by return line.

[0011]

According to the present invention, since the conveyor chain for transporting the article transport table is submerged in the water tank and operated, the particles of the spray paint scattered in the booth are blocked by the water liquid, and the conveyer chain is conveyed.
Since the paint adhesion to Nbeyachen is prevented, labor-saving maintenance work is achieved cleaned for attachment paint removal conveyor chain becomes unnecessary, also conveyor
Since the legs of the article carrier are placed directly on the chain , the placement timing can be set freely, and unlike the conventional push-and-forward transport using a pusher dog, the loading timing of the article carrier on the conveyor chain is produced. In addition to selecting the optimal transport according to changes in the amount and coating color,
The pulsation of the article carrier generated when the pusher dog is engaged
Can be prevented, and traveling guide on the conveyor side of the conveyor chain.
Conveyed goods and goods because they are supported by rails
Move the article carrier without bending downward due to the weight of the carrier.
There is an effect that the article carrier can be stably transported by being supported .
