Abstract

PURPOSE:To aim at preventing any coating from sticking to a travel device in a processing part, by forming a liquid tank in this processing tank, while setting up a travel driver for a travelable moving block having a processed material holding device at the upper end, inside this liquid tank, and constituting it to be submerged in a liquid. CONSTITUTION:A liquid tank 5 is formed at the floor side inside a processing chamber over a range from an inlet part to an outlet part, and an almost constant liquid 8 is stored therein. A moving block 10 supporting a processed material 19 by a supporting device 20 is traveled on a fixed route with each actuation of linear motors 26 and 27 as being guided by a rail 11. This moving block 10 is going into the liquid tank toward the outlet part from the inlet part by degrees, and the more lower part than an intermediate part of a longitudinal lever 21 of the supporting device 20 is submerged in a liquid together with the whole body of a travel driver 24. During this traveling, coating to the processed material 19 takes place, but dripping coating is dropped in the liquid so that direct coating sticking to the moving block 10 and the travel driver 24 is prevented from occurring.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates, for example, to a conveying device for a processing section employed in an automobile manufacturing factory to carry out painting, polishing, etc. while conveying a vehicle body. It is something.

2. Description of the Related Art Conventionally, this type of conveying device has been used, for example, in
As seen in Publication No. 2865, a trolley is provided that is supported and guided by rails and can move freely within the painting room.

A structure is provided in which a floor conveyor (cheno) having a protrusion that can be freely engaged with the cart is disposed along the rail, and water is poured into a channel-shaped frame that guides the floor conveyor. According to this, it is possible to wash away the paint on the cheno.

Problems to be Solved by the Invention However, according to the conventional method described above, paint adheres to the construction structure of the Cheno and the trolley, and then hardens.
Removal work is not easy.

The object of the present invention is to provide a traveling drive device, a bogie fζ
There is an object of providing a conveyance device for a processing section that prevents paint from adhering.

Means for Solving the Problems In order to solve the above-mentioned problems, the transport device for the processing section of the present invention includes a liquid tank formed in the processing section, and a processing object support at the upper end of the liquid tank. , and - a movable base that can freely travel along a fixed path is provided, and a travel drive device for the movable base is provided, and the liquid tank is configured to immerse the movable base and the travel drive device in liquid.

According to the structure of the present invention, dust and dripped paint generated during processing work on objects to be processed in the processing section fall on the liquid surface in the liquid tank and do not adhere to the movable table or traveling drive device. That is fζ.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 to 8.

The processing section (processing chamber) (1) is formed by a surrounding wall (2), and the surrounding wall (2) is formed with an inlet section (3) and an outlet section (4).The processing section (1) A liquid tank (5) is formed on the floor side from the inlet part (3) to the outlet part (4), and a liquid injection pipe (6) and a liquid drain pipe (7) are connected to this liquid tank (5). A constant liquid (water, etc.) (8) is stored by connecting the

A movable platform αQ is provided which can freely run on a fixed path (9) through the liquid tank (5) from outside the inlet (3) to the outside of the outlet (4).

That is, a left and right pair of rail circles are provided along a fixed path (9), and these rails I are laid across the tank bottom surface σ4f from the floor surface via base frames 4 spaced at appropriate intervals. A plurality of leg members α are hung from both sides of the main body (to) of the movable platform aO, and the lower ends of these leg members (11) are equipped with wheels Oη supported and guided by the rails c and A prevention roller (to) is attached.

The main body (to) Jzi moss is provided with a support 4 for a vehicle body α field, which is an example of an object to be transported. This support (7) consists of a plurality of vertical rods erected, horizontal rods attached to the ends of these vertical rods, and the supports provided on these horizontal rods (2) are boards. The receiver supports the seal portion (19a) of the vehicle body α by the plate 4. The travel drive device for the movable platform α0 is a beam near motor type, and the rail u°C
For installation fixed to the pace frame (2) side along the plate (A), the stator (to) of the linear motor is attached at predetermined intervals, and the lower surface of the main body (to) faces the stator (to). A linear motor mover is provided at the position where the

The liquid tank (5) has a vertical rod (2) whose liquid level is lowered to immerse the movable stand and the travel drive device (goods) in the liquid.
It is considered as the middle part. An automatic coating machine (E), which is an example of a processing device, is installed above the floor opening in the processing section (1).

Note that the coating may be performed manually. 0υ indicates a gangplank that can be moved in and out.

Next, the operation of the above embodiment will be explained.

A movable platform αQ that supports the vehicle body α9 with a support (7)
By operating the linear motor wb.

run. Then, the movable table αq enters the processing section (1) from the population section (3), but at that time, the liquid tank (
5), and the lower part of the vertical rod than the middle part is immersed in the liquid together with all of the travel drive device (2). While driving in this state, the automatic painting machine removed the car body CIl.
During the painting process, the paint that dripped was caught on the liquid surface (c).

Do not fall directly onto the movable platform σq or the traveling drive device (to).

After that, the movable table αQ passes through the exit part (4) and the processing part (
1) and travels to the primary process.

In the above embodiment, a linear motor type is shown as the travel drive device, but the entire fixed path (9) or the portion other than the part to be immersed in liquid may be of a chain drive type, for example. In the latter case, Figure 1.

As shown in FIG. 2, a passive protrusion is provided on the lower surface side of the main body.

FIG. 4 shows another embodiment of the invention. In other words, the liquid tank (5
) is composed of a frame body (1) and a see-through plate (tempered glass plate) (7), and its liquid level is set so that all of the vehicle body α is immersed in liquid. This type is used in electrodeposition line numbers.

Effects of the Invention According to the present invention having the above-mentioned configuration, dust and dripped paint generated during the processing of the object to be processed in the processing section fall onto the liquid surface of the liquid tank, causing damage to the movable platform and traveling drive device. can be prevented from adhering to and solidifying. This makes it possible to omit the work of removing paint from the movable platform and travel drive device, which have complex shapes, and to clean the inside of the liquid tank by constantly flowing the liquid. Periodic fζ washing is easier than Iζ. Furthermore, by using a liquid tank, explosion-proof effects can be expected.
