[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for attaching a brush to the tip of a coating head, and more particularly, to a structure that facilitates replacement of a brush frequently.

[0002]

2. Description of the Prior Art Conventionally, as shown in FIG.
The bracket 2 is detachably attached with bolts 3, and two strip-shaped brushes 4 are overlapped, and the two brushes 4 are bent in a U-shape in a horizontal direction, so that the brushes 4 are arranged between the upper and lower brackets 2.
Is held. When the brush 4 is worn or replaced, one of the upper and lower brackets 2 is removed, the old brush 4 is removed, the new brush 4 is folded in a horizontal U-shape, and the brush 4 is placed between the upper and lower brackets 2. Pinch,
The removed bracket 2 is attached again with the bolts 3, and the brush 4 is sandwiched between the upper and lower brackets 2.

[0003]

However, in the above-described conventional example, the brush 4 is deformed against the elastic force of the brush 4 because the brush 4 is sandwiched between the upper and lower brackets 2 and attached. The bracket 2 must be mounted by holding down the bracket 2 and tightening the bolts 3 while holding the bracket 2 in a predetermined position, and there is a problem that it takes time to replace the brush 4. This type of brush 4 is changed once a day by an operator.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide a brush mounting structure of a coating head that allows easy replacement of a brush.

[0005]

In order to achieve the above object, the present invention provides a brush mounting structure for a coating head.
In the brush mounting structure of the coating head, the bracket 2 is detachably attached with the bolt 3 so as to be opposed to the top and bottom of the coating head, and the band-shaped brush 4 is bent in a horizontal U-shape and attached between the upper and lower brackets 2. A rectangular tubular holding body 5 is provided at the end of one of the brackets 2 and a holding screw 6 is screwed into the holding body 5 so as to protrude from the outer surface of the holding body 5 to the inner surface thereof.
It is characterized in that the brush 4 bent in a letter shape is inserted into the holder 5 and the brush 4 is pressed and supported in the holder 5 by the holding screw 6.

[0006]

When replacing the brush 4, the bracket 2 provided with the holding member 5 is removed by removing the bolt 3, the cap screw 6 is loosened, the old brush 4 is taken out, and the new brush 4 is folded in a horizontal U-shape to obtain a new one. The end of the brush 4 is inserted into the holder 5 and the holding screw 6 is tightened to hold the new brush 4 on the holder 5, and the bracket 2 is attached to the painting head 1 again with the bolt 3. Since the brush 4 can be exchanged in this manner, the bracket 2 is pressed and held so that the brush 4 is deformed against the elastic force of the brush 4, and the bolt 3 is tightened while holding the bracket 2 in a predetermined position, as in the related art. The brush 4 can be replaced without having to handle the bracket 2 by attaching it, and the brush 4 can be easily replaced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a coating head 1 is attached to a tip of a robot arm 7 via a connecting portion 8, and a bracket 2 is disposed on the tip of the coating head 1 vertically. The bracket 2 is detachably attached with a bolt 3. In the case of the present embodiment, the upper bracket 2a of the upper and lower brackets 2 is normally not removed. A bottomed rectangular cylindrical holder 5 is integrally provided on the tip of the lower bracket 2 b of the upper and lower brackets 2, and a holding screw 6 is provided on the upper part of the holder 5.
Is screwed. The holding screw 6 is screwed so that the tip of the holding screw 6 projects from the outer surface to the inner surface. A projection 9 serving as a spacer is provided on the upper surface of the holder 5 so as to project therefrom. In addition, an insertion hole 10 is formed substantially at the center of the side surface of the holder 5, and a tip of a tube 11 such as a micro tube for supplying a paint from the robot side is inserted through the insertion hole 10. The brush 4 is formed by providing a flocked portion 4b on one side of a sponge 4a. This brush 4 is 2 as shown in FIG.
The brushes 4 are folded in a U-shape as shown in FIG. 3 (b) in a state where the brushes 4 are stacked, and the brush 4 is turned sideways into a U-shape as shown in FIG. 3 (c). The end is inserted through the holding body 5, and the brush 4 is held by tightening the holding screw 6. The tip of the tube 11 inserted into the insertion hole 10 is introduced into the brush 4.

Thus, the coating head 1 is moved by the robot while the coating material is supplied from the tube 11, and the brush 4 is moved along the object to be coated. In this way, coating such as tincture coating is performed. Zinc coating is to apply zinc rich paint to repair plating. The paint is applied in this way, and the brush 4 is usually 1
It is replaced once a day and replaced as follows.
Remove the lower bolt 3 and the lower bracket 2b together with the holder 5 and loosen the cap screw 6 to remove the old brush 4
Is taken out and a new brush 4 is bent into a U-shape to
Is inserted into the holder 5, the holding screw 6 is tightened to hold the brush 4 on the holder 5, and the bracket 2 a is attached to the coating head 1 again with the bolt 3. Bracket 2
A large number of attachments provided with the holding body 5 in b are prepared as attachments, and the brush 4 is attached to the holding body 5 in advance. It can be done instantly, and the operation rate of the equipment improves.

[0009]

According to the present invention, as described above, a rectangular cylindrical holder is provided at the end of one of the upper and lower brackets, and a holding screw is screwed on the holder so as to project from the outer surface of the holder to the inner surface. When the brush is replaced, since the brush bent in a U-shape is inserted into the holding body and the holding screw presses and supports the brush in the holding body,
Remove the bracket provided with the holder by removing the bolt, loosen the holding screw, take out the old brush, bend the new brush in a horizontal U shape, insert the end of the new brush into the holding body, and tighten the holding screw The new brush can be held by the holder, and the bracket can be attached to the painting head again with bolts.The replacement of the brush can be easier than in the past. Prepare a large number of attachments with the holding body as an attachment, and attach a brush to the holding body in advance, you can change the brush just by replacing the attachment by attaching and removing bolts, and the equipment can be operated instantly The rate is improved.
