Description

Detailed Description of the Invention

[0001]

INDUSTRIAL APPLICABILITY The present invention provides a matte finish on the surface of glass, aluminum plate, wood and other materials to be treated so that matte treatment and smooth surface treatment can be performed uniformly and uniformly. The present invention relates to a flat polishing machine.

[0002]

2. Description of the Related Art Conventionally, sandblasting has been proposed in which an abrasive having a small particle size is sprayed on the surface of glass, aluminum plate, wood or the like, and the surface is satinized. In this sandblasting, there are gravity type, siphon type, direct pressure type, etc. as an air system for spraying the abrasive material by using the injection energy of compressed air, and as a centrifugal projection method without using compressed air, a rotating impeller is used. There is one in which the abrasive supplied from the center is struck by centrifugal force from the outer circumference of the impeller. Further, there is a flat type in which an abrasive material is naturally and broadly dropped like a waterfall cloth, and an impeller having a wide lateral width is used in the middle to strike the abrasive material for acceleration.

[0003]

However, the above-mentioned conventionally proposed air system, generally called a sandblasting device, has a lateral width in order to forcibly spray the abrasive from the thin nozzle tip onto the material to be treated. For the material to be treated having a large number, it is performed while meandering on the surface. Therefore, the polishing process cannot be carried out uniformly, resulting in light and shade, and a so-called striped pattern appears.
It was difficult to polish the surface of a material having a large width with a sandblasting apparatus of this type.

Further, in the case of the centrifugal type, if the projection port is made large so as to be able to handle a material having a large width, the impeller itself becomes extremely large, and its rotating mechanism and its load bearing are supported. Since the structure, the polishing material supply mechanism, and the like inevitably become large in size, a large installation space is required, the mechanism becomes complicated, and its maintenance must be troublesome.

On the other hand, what has been conventionally provided as a flat type polishing machine has a processing lateral width range of about 900 mm in the material to be processed, and polishing of a material having a wider width than that is possible. It was difficult. Because of the fact that the abrasive material is dropped and supplied into the space between the blade materials, it is not possible to make the blade material that strikes the abrasive material long, and it is not possible to uniformly supply the abrasive material to the entire blade area. It was because I could be named.

Further, in such a conventional polishing processing machine, after the material to be processed is carried into the processing machine and subjected to the polishing processing, it is carried out in the reverse direction from the carry-in port.
The processing time required for a series of operations such as carrying-in, polishing, carrying-out and the like becomes substantially long, which is not only efficient, but automation for carrying the material to be processed in one direction is completely impossible.

Therefore, the present invention was created in view of the various existing conditions as described above. Mainly, even for a material to be processed having a large lateral width, the light and shade is distributed over the entire surface to be processed. Since it can be uniformly polished without causing it, and can be processed while conveying the material to be processed in one direction, it can be used continuously and automatically and can be easily incorporated into an automated processing line. An object is to provide a surface polishing machine.

The tree invention is constructed as described above,
As a result, even with a wide workpiece W having a considerably large width, the abrasive S can be dispersed and uniformly projected over the entire surface of the workpiece by a uniform striking action. In addition, since the workpiece W is processed while being conveyed in one direction from the carry-in port 2 to the carry-out port 3, it can be continuously and automatically integrated into an automated processing line. Can be easy.

That is, according to the present invention, while the glass material, the aluminum plate material, the wood, and other predetermined material W to be processed are conveyed by the projection device 20 from the front carry-in port 2 of the body frame 1 to the rear carry-out port 3. Then, for the workpiece W,
A polishing device S that removes the polishing material S and the like from the surface of the processing target material W after polishing and blasting is performed by using a striking type projection device 20 that uniformly disperses the polishing material S in a region substantially orthogonal to the transport direction and forcibly strikes the polishing material S. After being removed by scraping and sucking, the abrasive S and other dust in the vicinity of the carry-out port 3 is also sucked and cleaned by the dust suction device 70, and further, after the sucked abrasive S and dust are separated, This is because the reusable abrasive material S is supplied again to the projection device 20 by the circulation separation device 90, and thereby, the matting treatment, the smooth surface treatment, etc. can be performed uniformly without light and shade. Of.

Further, the striking mechanism 21 and the abrasive supply mechanism 26
When the plurality of striking blade plates 25 arranged substantially orthogonal to the conveyance direction of the material to be processed W are swung, the projection device 20 equipped with is forced to the abrasive material S which is sequentially dropped and supplied below the impact blade plates 25. Since the object W to be processed conveyed below the hitting blade plate 25 has a wide width, it is possible to perform uniform polishing processing on the entire processing surface. . Therefore, it is possible to obtain a beautiful processed product having a good appearance without causing local light and shade, a striped pattern and the like as in the conventional case, and also to obtain a glass material, an aluminum material, wood, and other predetermined materials. It enables polishing of various materials.

Further, the flow rate adjuster 28 in the abrasive material supply mechanism 26 has the abrasive material S which strikes the material W to be processed.
It is possible to freely change the supply amount of the powder to finely adjust the depth of polishing, the degree of coarseness and fineness, and the dispersion means 45.
Is to uniformly disperse the abrasive material S dropped and supplied from the flow rate regulator 28 along a direction substantially orthogonal to the transport direction of the material W to be processed, and to uniformly perform the polishing processing. Since the striking mechanism 21 having the striking blade plate 25 and rotating is arranged in the cover 22, when striking the abrasive S,
The abrasive S is not scattered around and the burden of removal and cleaning in the frame 1 is not added.

The dust removing device 70 including the cleaner duct 61, the cleaner hood 62, the air injection mechanism 71, and the suction mechanism 81 hits the workpiece W by the projection device 20 in the frame frame 1. Is
An abrasive material S attached to or left on the surface of the material W to be processed,
Further, it is possible to remove the processing wastes and other dusts attached after polishing, so that the processing target material W carried out from the carry-out port 3 can be directly processed in the next step. At this time, in the removing device 60, the scraping piece 64 is the workpiece W.
The abrasive material S and the like are collected in a scraped manner from above, and in the dust suction device 70, after the unnecessary material is blown off from the material to be treated W so that it is forcibly separated by the air injection mechanism 71, the vacuum type Since it is sucked into and removed by the
Very little is left on top.

The circulation separation device 90 comprises a dust collecting mechanism 91, a sorting mechanism 101, and a supply mechanism 115, and the removing device 6
0, it is sucked in by the dust suction device 70, and the body frame 1
Abrasive S removed from the material to be treated W in the interior is sorted into reusable abrasive S and unnecessary dust and the like, and then the reusable abrasive S is collected and projected. Since it is supplied to No. 20, the polishing material S is not wasted.
