Description

Description: TECHNICAL FIELD The present invention relates to a wiping method and apparatus for performing wiping after coating of a base paint, which is performed as a pretreatment work for coating a plate material.

(Prior Art) When painting a plate material used for furniture or the like, a base paint is applied as a pretreatment work.

Japanese Patent Laid-Open No. 1-2071
The one described in Japanese Patent Publication No. 67 is known. This prior art is characterized in that the surface of the plate material is rubbed by a rotary brush while the wiping medium is sprayed on the plate material coated with the base coating material to wipe off the base coating material applied to the surface of the plate material. Further, in the above publication, it is disclosed that the wiping medium is preferably wood scraps, and specifically, sawdust or planed scraps correspond thereto.

Since the wiping work according to the conventional technique uses a wiping medium such as wood scraps, there is a problem that minute pieces of wood scatter during the wiping work, leading to a deterioration of the factory environment. Since it is desirable that the painting for finishing the product is performed in clean air, the above-mentioned wiping of the base paint and the painting of the finish paint are in different environments from each other, that is, even in the same factory, in different areas. However, it is important not to deteriorate the factory environment even in the work of wiping the base paint.

(Problems to be Solved by the Invention) The present invention wipes off the base paint by rotating the brush roller and absorbs the base paint adhering to the brush roller on a wiping belt made of paper or cloth. It is an object of the present invention to provide a wiping method and device that do not use a medium caused by shavings.

(Means for Solving the Problem) A first means for achieving the above object is to configure a conveyor by arranging an upper brush group and a lower brush group in which a plurality of brush rollers are arranged in parallel vertically. Each of the brush rollers is connected to a rotation driving device so that the plate material supplied between the upper and lower brush groups can be rotated in a direction to send the plate material to one side, and a wipe made of paper or cloth is provided on the opposite side of the wiping surface of each brush roller. The second means is adjacent to the end of the brush conveyor, is orthogonal to the rotation axis of the brush group, and is opposed to the first means with respect to the first means. It is characterized in that a pair of vertical brushes and a wiper belt made of paper or cloth joined to the opposite side of each wiper surface of the vertical brush are attached.

(Function) The plate material fed between the upper and lower brush groups 2 and 4 is rubbed by the brush rollers 1 and 3, and excess paint on the surface (upper and lower surfaces) of the plate material is wiped off. The paint adhered to the brush rollers 1 and 3 is absorbed by the wiping belts 7 and 8.

The plate that has passed through the upper and lower brush groups has a vertical brush
Scrape with 6 and wipe off excess paint. The paint adhered to the vertical brushes 5 and 6 is absorbed by the wiping belts 17 and 18.

(Embodiment) FIG. 1 is a sectional view showing the structure of a wiping device, and FIG. 2 is a plan view. In the drawing, brush rollers 1 and 1 are arranged in parallel to constitute an upper brush group 2, and brushes having the same structure are used. The lower brush group 4 is formed by arranging the rollers 3 in parallel, and the upper brush group 2 and the lower brush group 4 are arranged in a pair in the upper and lower direction with a sufficient spacing to wipe off the base paint applied to the plate-shaped material. Arranged to form a conveyor. And each brush roller 1,
A rotary drive mechanism 3 is connected so that the plate material supplied between the brush groups 2 and 4 can be conveyed in one direction.

In the embodiment, each brush roller rotates so that the plate material is conveyed from right to left. The number of brush rollers forming the brush group is not particularly limited.

In the upper and lower brush groups 2 and 4, the front and back surfaces of the plate material are rubbed with a brush to wipe off the base paint, but since the side surfaces of the plate material are wiped off, they are adjacent to the ends of the upper and lower brush groups, and the rotation axis of the brush group is Vertical brushes 5 and 6 in a direction orthogonal to the are provided so as to face each other and form a pair. The vertical brushes 5 and 6 are also connected to a rotary drive mechanism, and move in the direction of scraping the side surface of the plate material carried out from the brush groups 2 and 4 and carrying it out from the wiping device. Since the width of the plate material is not specified, the vertical brushes 5 and 6 can accommodate plate materials of different sizes by incorporating a mechanism capable of moving the brushes 5 and 6 in a direction of approaching or separating from each other.

An upper wiping belt 7 and a lower wiping belt 8 are joined to the opposite sides of the wiping surfaces of the upper brush group 2 and the lower brush group 4. In addition, the lower wiping belts 7 and 8 are made of paper or cloth, and are made of a material having a function of absorbing the base paint.

Both ends of the upper wiping belt 7 are wound around the winding shafts 9 and 10, and the lower wiping belt 8 is wound around the winding shafts 11 and 12, of which the winding shafts 10 and 12 are wound. Is connected to the drive shafts of motors 13 and 14 and chains 15 and 16. The wiping belts 7 and 8 absorb the base paint adhered to the brush groups 2 and 4,
The effect of wiping each brush 1, 3 of the bush group is ensured. Therefore, when the absorbing power of the wiping belts 7 and 8 decreases, the motors 13 and 14 are driven to wind the winding shafts 10 and 1.
Rotate 2 and feed a new wiping belt to brush groups 2 and 4. The motors 13 and 14 may rotate at a very low speed during the wiping operation to wind the wiping belts 7 and 8.

The vertical wiping belts 17 and 18 are also joined to the vertical brushes 5 and 6 described above.
It is wrapped around 9,20. Although not shown,
One of the take-up shafts 19 and 20 is connected to a rotary drive mechanism so that the belt can be intermittently moved.

21 With the vacuum cover provided on the bottom surface of the lower brush group 4,
An air passage 22 for supplying negative pressure air is connected so that the gas generated from the organic solvent contained in the base paint can be carried out. Reference numeral 23 is a plate material coated with a base paint.

The embodiment has the above-mentioned configuration, and in the figure, the brushes are rotated so that the plate member 23 is carried in from the right side and is carried out to the left side. The brush rollers 1 and 3 convey the plate material 23 fed between the brushes toward the right side, and wipe off an excess of the base paint on the surface of the plate material. Although the brush roller itself performs the work of wiping off the paint, since it does not absorb the paint, the paint of the plate material is wiped off by adhering to the brush, and the wiping effect is reduced with the paint remaining on the brush.

In the present invention, since the brush groups 2 and 4 are joined to the wiping belts 7 and 8 which have the function of absorbing the paint, the paints attached to the brush rollers 1 and 3 of the brush group are wiped with the wiping belts 7 and 8. Is absorbed by. Therefore, the wiping effect of the brush group can be maintained, and continuous work can be performed without replacing the brush. Similarly, the vertical brushes 5 and 6 also absorb the paint adhering to the brushes by the vertical wiping belts 17 and 18,
The brush wiping effect is maintained.

The wiping belts 7, 8 and the vertical wiping belts 17, 1
When the wiping effect of 8 is deteriorated and the belt is deteriorated, the belt is unwound by the rotation drive mechanism and a new belt is joined to each belt, so that the wiping operation can be continued.

Since negative pressure air is supplied to the vacuum cover 21, the gas generated from the organic solvent mixed with the base paint can be sucked and discharged.

(Advantages of the Invention) The present invention wipes the base paint applied to the plate material with a brush roller, and joins a wiping belt that absorbs the paint to the brush roller so that the paint adhering to the brush roller is absorbed by the wiping belt. Since I tried to wipe off the paint,
It is possible to wipe off the paint that does not use the conventionally used wiping medium. Therefore, the minute wood pieces generated from the wiping medium do not adhere to the plate material, and not only the wiping operation can be performed quickly, but also the deterioration of the factory environment due to the wiping medium can be prevented.
