Description

Description: TECHNICAL FIELD The present invention relates to a wiping device that wipes off excess base paint in the application of base paint performed as a pretreatment work for coating plate materials.

(Prior Art) Japanese Patent Application Laid-Open No. HEI-1 is a conventional method for wiping off a base paint.
The one described in JP-A-207167 is known. This prior art is characterized by wiping off excess base paint by rubbing the surface of the plate with a rotating brush while spraying a wiping medium on the plate coated with the base paint.
The wiping medium is sawdust or planks as shavings of wood.

The conventional wiping work uses a wiping medium made of wood shavings, so the wiping medium is colored by the base paint, and when the base paint changes, it is necessary to replace the medium with a new one. The work must be interrupted in order to change the medium. The wiping medium is replaced with a new one in anticipation of the time when the wiping effect has deteriorated, but it is used repeatedly until then. For this reason, the wiping medium may be replenished with new one as long as the base paint does not change, but when the base paint changes and the base paint of a different color from the previous time is wiped off, it is necessary to replace the wiping medium. There is a problem that it takes time to perform setup work.

Also, when using wood shavings as a wiping medium,
The wiping effect is good, but since the small pieces of wood adhere to the plate material, it is necessary to remove the small pieces of wood after wiping, and the small pieces of wood dance during the work, which causes the health of workers to be impaired. There are also problems such as being lost.

(Problems to be Solved by the Invention) An object of the present invention is to provide a wiping device that wipes off excess base paint with a wiping belt made of paper or cloth and that does not use a medium of wood particles.

(Means for Solving the Problem) Means for solving the problem in the present invention is to have an upper wiping belt 1 and a lower wiping belt 2 which are made of paper or cloth and wipe the surface of a plate material. The wiping belts 1 and 2 are wound around the winding shafts 3, 4, 5 and 6 in front of and behind the wiping belts 1 and 2 with a sufficient space therebetween, and the winding shafts are rotated and driven. 8, 11 and 12, the upper wiping belt 1 is provided with an upper vibrating plate 15 and the lower wiping belt 2 is provided with a lower vibrating plate 16 at positions where the respective wiping belts face each other. Vibration generators 19 and 20 are installed on the diaphragm, and cushion materials 17 and 18 are provided between the upper wiping belt 1 and the upper diaphragm 15 and between the lower wiping belt 2 and the lower diaphragm 16. It is characterized by.

(Operation) The upper wiping belt 1 and the lower wiping belt 2 move from right to left to sandwich and convey the plate material. The plate member 23 sandwiched between the upper and lower wiping belts 1 and 2 is conveyed by the vibrating plate 15,
The upper and lower surfaces are wiped off simultaneously by the vibration of 16
It is rubbed with 1,2 and the excess of the applied base paint is wiped off.

(Example) FIG. 1 is a block diagram of a wiping device according to the present invention. In the figure, a pair of wiping belts, an upper wiping belt 1 and a lower wiping belt 2, are arranged vertically with a sufficient spacing for wiping the surface of a plate material. It is wound around 4, and the lower wiping belt 2 is wound around the winding shafts 5 and 6.
The upper and lower wiping belts 1 and 2 are made of paper or cloth, and are made of a material having an effect of wiping the base paint.

Reference numerals 7 and 8 denote motors that rotate the winding shafts 3 and 4 around which the upper wiping belt 1 is wound. The motors have a built-in one-way clutch and transmit the rotational force by the chains 9 and 10 or the timing belt. ing. Reference numerals 11 and 12 denote motors for rotationally driving the take-up shafts 5 and 6 around which the lower wiping belt 2 is wound. The motors also have a built-in one-way clutch. The torque is transmitted.

An upper diaphragm 15 and a lower diaphragm 16 are arranged at positions where the upper wiping belt 1 and the lower wiping belt 2 face each other. Rubber and other flexible cushioning materials 17, 18 are adhered to both of the diaphragms 15, 16 and contact the upper and lower wiping belts 1, 2 via the cushioning materials 17, 18. I am letting you. Further, the upper vibration plate 15 and the lower vibration plate 16 are equipped with vibration generators 19 and 20, respectively, and by operating the vibration generators 19 and 20, the upper and lower wiping belts 1 and 2 are Vibrate.

Further, a vacuum cover 21 is arranged on the lower surface of the lower diaphragm 16, and an air passage 22 for supplying negative pressure air is connected to the vacuum cover 21. Reference numeral 23 is a plate material coated with a base paint.

The embodiment has the above-mentioned configuration, and the plate member 23 is carried in from the right side and carried out from the left side in the drawing. The upper and lower wiping belts 1 and 2 move from right to left.
As the vibrating plates 15 and 16 are vibrated by the vibration generators 19 and 20, the upper wiping belt 1 and the lower wiping belt 2 vibrate.

The plate material 23 fed between the upper and lower wiping belts 1 and 2 is rubbed by the wiping belts 1 and 2 on the upper and lower surfaces by the vibration of the vibrating plates 15 and 16, and the extra base paint applied. Is wiped off. Since the upper and lower wiping belts 1 and 2 also serve to convey the plate material 23, after the completion of wiping, the motors 7 and 11 are driven to wind the belt and carry the plate material out of the work area.

The wiping belt rotates the winding shafts 4 and 6 in reverse by the motors 8 and 12 when all the belts wound around the winding shafts 4 and 6 are wound around the winding shafts 3 and 5 on the opposite side. And rewind. This operation is repeated several times to perform the wiping operation. If the belt deteriorates, replace it with a new one.

Since the belt can be wiped several times at the same position, the belt can be returned to the original position each time the plate material is carried out, and this operation can be repeated to feed out the deteriorated belt little by little. Therefore, this method is convenient when it is expected that the color of the base paint will change several times during the day.

The cushion materials 17 and 18 attached to the diaphragms 15 and 16 are for ensuring the adhesion of the belt to the plate material 23,
As a result, even a plate material having a curved surface can wipe off all surfaces including the curved surface.

On the other hand, since negative pressure air is supplied to the vacuum cover 21, the gas generated from the organic solvent mixed in the base paint can be removed by suction.

(Effect of the invention) Since the present invention is designed to wipe off excess paint of the base paint applied to the plate material with a paper or cloth wiping belt, it is possible to prevent dust and the like from adhering to the plate material, such as small wood chips. For this reason, it is not necessary to remove the small pieces of wood after the wiping operation, and the wiping operation can be carried out quickly and the work efficiency can be improved.

Further, according to the present invention, since the wiping belt can be intermittently fed out and used, a new unused portion is fed out and used when the belt is deteriorated, and an unused portion is fed out when the color of the base paint is changed. Since it is possible to respond immediately by just doing, there is an effect that the setup time can be shortened even if the color of the base paint changes.
