Description

[Detailed Description of the Invention] This invention relates to the disclosure of a new processing method for decorative gypsum boards, especially board materials having an uneven knitted pattern that can reliably express a sense of mass when used as a decorative material. It is something.

Therefore, the conventional means of decorating gypsum board was generally based on flat processing such as adding patterns to the base paper of the board itself, and it is hard to avoid the impression that it is a modern material as a decorative board material. there were.

The decorative board material with the base paper surface as the decorative surface in the previous example of Kaheru is derived from the material characteristics of gypsum board, especially the fact that the base paper has the gypsum material that is the core material. This is all due to the difficulty in post-processing the board base paper, especially cutting out the board base paper or scooping out the gypsum core material.

The present invention aims to break away from the flatness of the decorative gypsum board used as a decorative material in the prior art, and specifically provide the gypsum board with an uneven three-dimensional pattern that can fully bring out the sense of mass. The gist of its configuration is that it includes a slitter device that cuts the board base paper on the side surface of the gypsum board at appropriate intervals, and a slitter device that grooves the board along the cut edge of the board base paper that has been cut into sections. We installed a series of equipment structures consisting of a grinding device, a circular saw device for cutting the board into appropriate widths, and a vacuum device for cutting and grinding powder, and we planned to make considerable design changes in accordance with the gist of this configuration. It is something.

The present invention has the basic constitution outlined above to prevent wall collapse of the cut or cut edge of a gypsum board material, avoid cutting or cutting defects at the cut edge,
One objective that should be effective is rapid processing, and another objective that should be effective is to express a sense of material mass by creating a three-dimensional sense of mass and the internal surface of the board.

The details of the present invention will be described below with reference to a typical embodiment shown in the drawings.A machine housing 2 is placed on a machine base 1, and a slide rail 3 is installed on the machine base 1 via this machine housing 2. , and a workbench 5 having a surface plate 4 is slidably installed horizontally on the slide rail 3.

Next, a slitter 6, a circular saw 7, and a roll cutter 8 are sequentially mounted on shafts 9 to 9 at predetermined intervals on the upper part of the machine casing 2, and the pulleys 10 to 10 on the respective mounting shafts correspond to the pulleys 10. Belts 13 to 13 are mounted between drive shaft pulleys 12 to 12 of the respective motors 11 to 11 to restrict the driving of the attached shafts.

Further, the operating slide rail 3 of the workbench 5 installed on the machine stand 1 is installed so as to be perpendicular to the mounting axis of the slitter 6, etc., and to pass under the slitter 6, etc., and to be able to pass through the rail. The workbench 5 on the slitter 3 is sequentially guided to the slitter 6 and other processing devices.

Each of the processing devices installed on the machine casing 2 has a casing 14 whose bottom surface is open and covers the top surface, and a dust collection duct 15 is installed inside the casing 14 to allow the processing equipment to This dust collection duct 15 is designed to suction and remove cutting waste or cutting base paper generated during processing, and the dust collection duct 15 is basically arranged so that its 15° opening is located on the side circumferential surface of the roll cutter 8. This is what I did.

A series of these processing devices are designed to accommodate changes in the positioning of the surface plate 4, the thickness dimension of the board A to be processed, the cutting depth dimension, etc., and the shaft mounting frame 1 of each shaft mounting 9 section.
6 is configured to restrict vertical sliding along the tapered groove 17, and various structural examples are planned for vertical movement along the tapered groove 17.

Furthermore, the processing devices do not necessarily need to be installed in the order of the slitter 6, circular saw 7, and roll cutter 8 as in the illustrated example; As long as the circular saw 7 is installed in any position, it does not interfere with the operation of the device, and the position is appropriately determined according to the characteristics of the decorative board for processing and creation purposes.

Furthermore, in the slitter 6 placed diagonally above, 6a indicates a circular blade, 7a in the circular saw 7 indicates a circular saw blade, and 8a in the roll cutter 8 indicates a circular cutter. be.

The workbench 5 that guides the board A to be processed with respect to the processing equipment has a lift cylinder 19 for the surface plate 4 installed on a leg stand 18 installed horizontally across a pair of slide rails 3, and is vertically extendable and retractable. The vertical movement of the 4 portions of the surface plate is made using the slide taber guide surface 21 as a guide by means of a freely movable leg rod 20. When the surface plate 4 is lowered, the slitter 6
This is to prevent re-contact with other processing equipment.

Incidentally, the surface plate 4 on the workbench 5 allows the workpiece board A, which is supplied by a belt conveyor or the like from the side arrow X direction, to come into contact with the guide stopper 22 on the surface of the surface plate 4, and the surface plate 4 The suction ports 23 to 23 opened on the surface are used to ensure suction and fixation, and numeral 24 indicates an intake pipe that communicates with the suction ports 23 and the suction blower.

In the figure, reference numeral 25 indicates the duct opening of the dust collecting duct 15, and the ducts are connected as appropriate to trap the generated processing dust and the like.

The present invention has a characteristic configuration in which the board A is slanted upward.
Guided by the roll cutter 8, cutting out the board base paper on the surface of the board A and polishing and removing the board core material are performed as a series of steps, and after cutting the board A to the required width, it is turned over and placed on the workbench. Furthermore, when reprocessing the processed board A, the board A is moved 90 degrees on the surface plate 4 and fed into the same equipment, or After being sent out in the direction of arrow y, the material is fed into another device of the same type via a belt conveyor or the like to form grooves in a checkered pattern.

In the present invention, due to the configuration and working characteristics of the slanted position, the board base paper is completely cut off by the slitter 6 before the roll cutter 8 acts, and the roll cutter 8 performs the grinding process along this cut edge. As a result, deviation of the meat at the resection edge is reliably prevented, and it is possible to create a cut edge with a so-called pin angle.

That is, when the core material is extremely brittle and has no viscosity,
When a cutting blade, etc. is pressed from the outside, it induces destruction of the internal structure before cutting the surface material, which inevitably causes the material to shift, and the collapse of the internal material is due to the cutting of the surface material. As a result, it becomes impossible to completely cut along the cutting blade when cutting the surface material, and often results in a jagged cut edge that looks like a forced cut.

The present invention is aimed at cutting gypsum boards having such special structural characteristics, particularly for creating decorative grooves with pin angles, and is designed with a processing device having the above-mentioned characteristics. The pressurization mode can be substantially avoided with the intervention of the slitter 6, and the grinding of the gypsum core material portion where the board base paper does not exist can be ensured as a precise grinding process that corresponds almost immediately to the shape of the blade surface.

In addition, by pre-treating the board base paper, adhesion of blade dung to the blade 8a of the roll cutter 8 is avoided as much as possible, and this blade dung is further reliably prevented by the intervention of the duct 15, and the blade dung is prevented from adhering to the blade 8a of the roll cutter 8. This completely eliminates the problem of cutting defects.

The present invention makes it possible to mass-produce gypsum boards with a particularly remarkable decorative effect, full of mass, and at low processing costs using an inclined lifting device.
