Abstract

PURPOSE:To provide a wall panel grinding device which can make joint processing for the surface of a cement board easily and satisfactorily in workmanship, wherein the cement board is likely to generate a warp or deflection. CONSTITUTION:A wall panel grinding device comprises a suction attachment table 4 which is mobile in horizontal direction on a bade board 2 and is fitted at the surface A with a number of air suction holes 5... 5, a suction device 6 in communication with these suction holes 5... 5, a rotary shaft 7 arranged as confronting the surface 4A of the table 4 and perpendicularly to the moving direction of the table 4, and a plurality of rotary cogs 8... 8 for grinding which are mounted on the rotary shaft 7. Warp and/or deflection of the plate is corrected by the suction force, which together with accurate movement of the table 4, enables performing a joint processing of good workmanship.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall plate surface grinding apparatus, and more particularly to a wall plate surface grinding apparatus for applying unevenness such as a joining step or brick joint to the surface of a ceramic cement plate or the like. .

[0002]

2. Description of the Related Art Conventionally, ceramic cement boards have been very widely used as building boards. When these building boards are left as they are, the ground color of the surface is achromatic, and the surface becomes a smooth surface, so the design is poor. Attaching is done. Furthermore, in order to increase the watertightness at the time of joining or the fitting strength, the mating step and the actual step of fitting are formed by grinding or the like. Conventionally, the above-mentioned grinding work uses a device consisting of a caterpillar chain conveyor for transferring the formed plate material and a uniaxial rotating cutter arranged facing this caterpillar chain conveyor, and the surface of the plate material is transferred during the transfer process on the caterpillar chain conveyor. The necessary grinding was done.

[0003]

However, since the caterpillar chain conveyor of the above grinding device may be slightly displaced in the vertical and horizontal directions depending on the contact state with the supporting roller, the straight line of the concave line to be ground on the surface of the plate material. However, there is a defect that the quality such as the property and the uniform depth may vary. Further, the cement plate material is apt to be warped or bent after curing, and the deformation and the deviation of the caterpillar chain conveyor synergistically cause a problem such as joint processing. In addition, the number of recessed lines to be ground may differ depending on the application of the plate material.To cope with this, conventionally, one cutter is used for each recessed groove, and if necessary, Although these cutters have been exchanged, there is a drawback that it is very troublesome to perform the exchange work for each cutter.

[0004]

SUMMARY OF THE INVENTION In view of the above problems, the present invention provides a wall board surface grinding apparatus capable of easily performing a good quality joint processing on the surface of a cement board which is apt to warp or bend. It was made for the purpose of obtaining.

[0005]

That is, the apparatus for grinding a wall plate surface according to the present invention is capable of moving horizontally on the substrate 2 and has a large number of air suction holes 5 ... 5 provided on the surface 4A. The suction table 4, a suction device 6 communicating with the air suction ports 5 ... 5 of the suction table 4, and a rotation facing the surface 4A of the suction table 4 and orthogonal to the moving direction of the suction table 4. It is characterized by comprising a shaft 7 and a plurality of grinding rotary teeth 8 mounted on the rotary shaft 7.

[0006]

Embodiments of the present invention will be described below. FIG. 1 is a side view of an embodiment of the present invention, and FIG. 2 is a plan view of the embodiment.

The wall plate surface grinding processing apparatus 1 of the present invention is capable of moving horizontally on a base 2 which is firmly mounted, for example, via a linear bearing, a sliding rail 3 and the like, and has a large number of surfaces 4A. Of the suction table 4 and the air suction ports 5 of the suction table 4 ...
5, a suction device 6 such as a suction pump communicating with 5, a rotary shaft 7 facing the surface 4A of the suction table 4 and orthogonally arranged to the moving direction of the suction table 4, and a plurality of rotary shafts mounted on the rotary shaft 7. The rotary teeth 8 for grinding.

In the above embodiment, the air suction holes 5 ... 5 and the suction device 6 are communicated with each other by forming a hollow inside the suction table 4 and communicating with the hollow via the flexible pipe 6A.

[0009]

When the surface of the cement plate material is ground by the wall plate surface grinding apparatus 1 of the present invention, the target plate material G is placed on the adsorption table 4 and the suction device 6 is driven to adsorb it. At this time, the plate material G is strongly adsorbed to the surface of the adsorption table 4 by the suction force, and even if there is a warp or a deflection, these are corrected and become a flat state. Next, the rotary shaft 7 is rotated and the suction table 4 is moved in the horizontal direction. Along with the movement of the suction table 4, the plurality of grinding rotary teeth 8 attached to the rotary shaft 7 are cut all at once on the surface of the plate material G to form a desired recess. Since the suction table 4 is supported so as to move in the horizontal direction, it has good linearity.
In addition, a concave line with a uniform depth is formed.

[0010]

As described above, the present invention provides the plate material G.
Since the suction table 4 is sucked and supported by the suction table 4, warpage and deflection are corrected, and since the suction table 4 moves in the horizontal direction without causing a slight deviation, surface grinding can be performed very accurately and stable processing can be performed. You can do it. Further, since the plurality of rotary teeth 8 ... 8 are provided on the same rotary shaft 7, the adjustment of the groove intervals and the like can be performed very easily, and various effects can be obtained, such as being able to efficiently cope with the case where high-mix low-volume production is performed.
