Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and a method for removing powder such as cutting chips attached to the outer surface of an article such as a resin plate.

[0002]

2. Description of the Related Art As a method for cutting a resin plate, there are methods such as cutting with a knife, cutting with a laser beam, cutting with high-pressure water, and cutting with a circular saw. Among these methods, the cutting method using a circular saw is inexpensive and easy to handle, but has the disadvantage that chips are generated when cutting the resin plate.

[0003] Since the generated chips easily adhere to the surface of the resin plate, it is necessary to remove the chips. As a method of removing chips, a method of sucking and removing generated chips when cutting a resin plate with a circular saw is exemplified.

[0004]

However, it is difficult to remove most of the chips attached to the surface of the resin plate by the method of removing generated chips by suction.

[0005]

SUMMARY OF THE INVENTION The gist of the present invention resides in an apparatus for removing powder attached to the outer surface of a conveyed article, the apparatus comprising a movable brush.

[0006] Further, the gist of the present invention is an apparatus for removing powder adhered to the outer surface of an article to be conveyed, which is a powder removing apparatus having a planar material capable of contacting the outer surface of the article.

[0007] Further, the gist of the present invention is a method for removing powder adhered to the outer surface of a conveyed article, wherein the movable brush moves on the outer surface of the article.

[0008] Further, the gist of the present invention is a method for removing powder adhered to the outer surface of an article to be conveyed, wherein the method is a powder removing method in which a planar object is brought into contact with the outer surface of the article.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, examples of articles from which powder adhering to an outer surface are removed include plate-like objects such as resin boards and wooden boards. Examples of the powder to be removed include swarf and foreign matter.

[0010] In the powder removing apparatus having the movable brush of the present invention, the movable brush may be a thin rod-shaped material made of a material such as a resin or a natural fiber,
Brushes in which synthetic fibers, animal hairs, or the like are implanted may be used. It is preferable that the outer surface of the article is not damaged when the movable brush moves on the outer surface of the article. When the movable brush moves on the outer surface of the article, it is preferable that the movable brush generate less static electricity.

The powder attached to the outer surface of the article can be removed by moving the outer surface of the article to which the movable brush is conveyed as described above. Preferably, the speed at which the articles are conveyed is constant. The method of moving the movable brush is not particularly limited. As an example, there is a method in which a plurality of brushes are arranged on an endless belt made of metal or resin, and the brush is moved on the outer surface of the article by rotating the endless belt. Another method is to move the brush on the outer surface of the article by rotating the brush longer than the length or width of the article.

[0012] In the method of moving the brush by the endless belt, a method of moving the brush from the inside to the outside of the outer surface of the article is preferable. Chips and the like collected by the brush can be sucked by a suction device. By discharging air or the like to the powder collected by the brush, the powder can be removed from the outer surface of the article.

[0013] In the powder removing apparatus of the present invention having a planar material that can be brought into contact with the outer surface of the article, examples of the planar material include a cloth made of natural fiber or synthetic fiber, a film made of synthetic resin, and the like. The size of the cloth or film is preferably larger than the length or width of the conveyed article. The thickness of the cloth or film is preferably 2 mm or less.

[0014] One end of the cloth or film is preferably attached to a pipe provided with a gas discharge hole. It is preferable that one end of the cloth or film is attached near the gas discharge hole. Examples of the shape of the gas discharge hole include a shape such as a circle, an ellipse, a triangle, a square, a rectangle, and a polygon, and a slit shape. The gas discharge hole has one hole area of 1 to
It is preferably about 30 mm ² . Preferably, a plurality of gas discharge holes are provided.

[0015] It is preferable that the gas is discharged from the gas discharge hole toward the outer surface of the article. In this case, the powder adhering to the outer surface of the article is removed by the gas discharged from the gas discharge hole toward the outer surface of the article. Further, the gas discharged from the gas discharge hole toward the outer surface of the article causes fluttering of a cloth or a film to come into discontinuous contact with the outer surface of the article to remove powder.

Further, gas can be discharged from the air discharge hole toward the planar object. In this case, the powder adhering to the outer surface of the article is removed by fluttering a sheet-like material such as a cloth or a film and coming into discontinuous contact with the outer surface of the article.

The gas discharged from the gas discharge hole on the outer surface of the article includes air and the like. The pressure of the discharged gas is 100
It is preferably 0 kPa or less.

[0018]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a case where an article is a resin plate will be described.

[Example 1] 1380 mm in width and 1120 m in length
m, a resin plate having a thickness of 3 mm and having a large amount of swarf adhered to the outer surface is conveyed at a rate of 2 m / min while the width of the resin plate is 8 mm.
Chips were removed with a brush having many horse hairs implanted in an area of 5 mm and 50 mm in length. A large number of brushes were moved at a speed of 40 cm / sec from the center of the resin plate surface in the left and right directions in the transport direction. Almost all of the chips attached to the resin plate were removed.

[Embodiment 2] In Embodiment 1, instead of the movable brush, 61 gas discharge holes having a diameter of 2 mm are provided at intervals of 25 mm, and the length is 1600 mm and the outer diameter is 21.7 m.
m, a pipe made of metal having an inner diameter of 16.1 mm was placed 5 cm above the surface of the resin plate to be conveyed, parallel to the surface of the resin plate, and perpendicular to the resin plate conveyance direction. The gas discharge hole was directed downward by 30 ° from the horizontal direction toward the upstream side in the resin plate unloading direction. 130mm long and 1600m wide above the gas discharge hole
m, 0.2mm thick cotton cloth attached, about 40
Air was discharged at a pressure of 0 kPa. Almost all of the swarf adhering to the resin plate was removed by the discharge air and the cloth fluttered by the discharge air contacting the resin plate surface discontinuously.

[0021]

According to the present invention, powder such as cutting powder can be removed from an article such as a resin plate.
