Description

[Detailed Description of the Invention] The present invention relates to a painting trolley suitable for painting large structures made of plastic materials.

Conventionally, the large structures of automobiles have mainly been made of steel plates, and the surfaces are painted with designs, but the back surfaces are made of separate parts, such as interior materials made of resin parts, decorative plates, etc. Since it was hidden by the decorative parts, there was no need to apply any special decorative coating to the back side.

However, in recent years, with the aim of reducing the weight and cost of automobiles, large plastic parts, such as fiber-reinforced plastic (FRP), have been used for automobile structures, and the design of interior materials, decorative panels, etc. It became necessary to apply design paint to both the front and back sides instead of parts. When painting plastic parts, the plastic parts are placed on a painting trolley and transported into a painting booth, and after first painting one side (the front or back side), a worker moves the plastic parts to another. After that, the other side was painted. For this reason, the work to replace plastic parts becomes complicated.
Not only does the worker come into contact with the painted surface, causing paint defects, but also the problem of requiring a trolley, space, etc. for transfer.

This invention was made to solve the above-mentioned problems, and the purpose is to provide a rotation mechanism to the cart that holds the object to be coated, so that painting can be done using the same cart, so that it can be easily transferred. To provide a painting trolley that can completely eliminate work and the occurrence of painting defects.

The above-mentioned object of the present invention is to provide a trolley body having a plurality of rotatable wheels with two support members disposed upright with a space between them, and between the support members,
Painting characterized in that a holding frame having a plurality of clamps for holding an object to be painted is rotatably supported, and the supporting member is provided with a positioning mechanism for regulating the rotational position of the holding frame. This is accomplished by using a trolley.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is a perspective view of the painting cart according to the present invention, Fig. 2 is a perspective view showing the holding frame of the painting cart shown in Fig. 1 in a rotated state, and Fig. 3 is the painting shown in Fig. 1. FIG. 3 is an enlarged perspective view showing a positioning mechanism of the trolley. 1st
In the drawings and FIGS. 3A and 3B, reference numeral 1 denotes a truck body, and this truck body has two horizontal members 3, 3a to which rotatable wheels 2 are attached to both ends, and these horizontal members 3, 3a are fixed. The horizontal members 3, 3a of the main body 1 are provided with two supporting members 5, 5 in the center thereof.
a are arranged upright at intervals. Rotating shafts 6, 6a rotatably supported by bearings (not shown) are provided at the upper ends of the supporting members 5, 5a, one end of which extends toward the opposite sides, and A cover 16 is provided. Further, a rectangular holding frame 7 to which upright reinforcing members 7a are fixed to the upper surface on both sides is disposed between the supporting members 5 and 5a, and this holding frame 7 is located at the portion of the reinforcing member 7a. Rotating shaft 6, 6a
It is rotatably supported by. A plurality of clamps 8 for holding the object W to be coated are provided around the periphery of the holding frame 7.

Further, the support member 5 is provided with a positioning mechanism 9 for regulating the rotational position of the holding frame 7. As shown in FIG. 3, this positioning mechanism 9 is composed of a semicircular rotating plate 10 fixed to the reinforcing member 7a of the holding frame 7, and a locking mechanism 11 for fixing the rotating plate 10. There is. And the rotating plate 10
Through holes 10a, 10b are formed in the circumferential surface of the rotating plate 10.
A spring 13 that urges this lock pin 12 toward the rotating plate 10, a cylindrical body 14 that accommodates this spring 13 and a part of the lock pin 12, and a cylindrical body 14 that penetrates through this cylindrical body 14 and has one end. It consists of a push rod 15 that is fixed to a lock pin 12 and has a push plate 15a fixed to the other end.

Then, by pulling the push rod 15 toward you,
The lock pin 12 comes out of the through hole 10b of the rotating plate 10, the holding frame 7 freely rotates, and the push rod 15
By returning the lock pin 12 toward the rotary plate 10, the lock pin 12 is inserted into the through hole 10a or 10b of the rotary plate 10, the holding frame 7 is fixed, and the rotating position is determined.

In the painting trolley configured as above,
Objects made from plastic materials include:
It is placed on the holding frame 7 by the clamp 8, and the locking pin 12 of the locking mechanism 11 is inserted into the through hole 10b of the rotary plate 10, so that the surface of the object W to be coated is positioned upward as shown in FIG. It is maintained as follows.
Then, in this state, it is transported to a coating booth (not shown), and the surface of the object W to be coated is coated by an operator. Thereafter, the lock pin 12 of the lock mechanism 11 is pulled by the operator and removed from the through hole 10b of the rotary plate 10, and the holding frame 7 is rotated to insert the lock pin 12 into the through hole 10a of the rotary plate 10. Then, the object W to be coated is tilted as shown in FIG. In this state, the back surface of the object W to be painted is coated.

After the coating has been completed, the object to be coated is transported to post-processes such as water grinding and drying, and is completed as a plastic part on which a coating film is formed.

In the present invention, the positioning device 9 has been described as a combination of the rotary plate 10 and the locking mechanism 11, but various other positioning mechanisms may be employed.

As explained above, in the painting trolley of the present invention, two support members are disposed upright with a space between them on the trolley body having a plurality of rotatable wheels. In between, a holding frame having a plurality of clamps for holding the object to be coated is rotatably supported, and a positioning mechanism for regulating the rotational position of the holding frame is provided on the supporting member, so that the same trolley can be used. Since the front and back surfaces of the object to be coated can be coated by this method, there is no need to change to a painting trolley as in the past, and there is an effect that the painting work efficiency can be significantly improved.

Moreover, since the operator does not come into contact with the object to be painted during the painting operation, there is an effect that the occurrence of painting defects can be completely eliminated.

Furthermore, with this invention, there is no need for a changeover work space during painting work, so
This eliminates the need for a trolley for transfers and has the effect of significantly reducing the size of the painting booth.
