Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a pattern forming method for an interior material such as a floor material by cutting the interior material into an arbitrary pattern. In this case, it is used when a pattern is formed by combining a plurality of tiles.

(Prior art) In recent years, there has been a trend to reconsider interior materials such as tiles and sheets attached to floors as advertising media and means of communicating intentions.
Many people are not satisfied with ready-made printed patterns and want an original design, and this pattern is not a small pattern drawn on each tile, but is formed by combining multiple tiles or sheets. Increasingly, large-area patterns are required.

When combining multiple tiles to form a pattern in response to the above requirements, conventionally, a skilled construction worker lays out and cuts the flooring material on the floor surface, and then glues and installs the cut flooring material. However, depending on the pattern, it is extremely difficult and time-consuming to apply, and there are various problems such as a lot of trial and error, waste of materials, and inefficiency. .

In order to solve the above-mentioned problems to some extent, a method for manufacturing an inlay tile has been proposed in which segments from two types of rough sheets of different colors are joined in a mutually complementary manner using a predetermined punching die (Japanese Unexamined Patent Application Publication No. 1983-1992-1). 113030).

However, this manufacturing method has the problem that the mold must be changed every time the pattern is changed, and it cannot be applied to a pattern that spans two or more tiles.

(Purpose of the Invention) The present invention aims to solve the above-mentioned problems by automatically cutting interior materials such as tiles and sheets into arbitrary patterns using a laser beam, and by making it possible to automatically cut interior materials such as tiles and sheets into arbitrary patterns. Not only can the material be cut into arbitrary patterns, but by combining these pre-cut segments, it is possible to easily form large-area patterns by combining a large number of tiles or sheets.

(Structure of the Invention) In order to achieve the above object, the present invention automatically cuts an interior material with a laser beam based on pattern data obtained by computer processing. In detail, data on the pattern of the interior material entered into the numerical controller activates the laser beam generator and the processing table at the coordinates located directly below the nozzle of the device, sets the injection nozzle at a predetermined position, and emits the laser beam. The interior material on the processing table is cut using the machine, and the pattern data for the interior material input into the numerical control machine is data obtained by converting the original drawing into a digital signal and then performing CAD processing. The present invention provides a method for forming a characteristic pattern on interior materials.

EXAMPLES The present invention will be explained in detail below using examples shown in the drawings.

FIG. 1 shows a partially cut-out apparatus for carrying out the method of the present invention, in which 1 is a cutting machine, 2 is a laser beam irradiation device provided in the cutting machine 1, 3 is a laser beam irradiation bag w12 and a cutting machine l. This is a control device that moves the processing table 4 according to the pattern.

The above-mentioned cutting machine 1 has a processing table 4 on the base 5 at the coordinates of X in the figure.
- The processing table 4 is connected to a conveyor belt 6 which is placed movably in the
Therefore, the processing table 4 can be moved to any position in the XX direction by driving the servo motor 7.

A laser beam irradiation device mounting frame 8.8 is erected from both sides of the processing table 4, and a conveyor belt 10 is installed between the mounting frames 8.8 so as to be able to circulate freely. A motor 11 is attached, and the servo motor 11 moves the conveyor belt 10 in the YY direction (perpendicular to the X-X direction). A laser beam irradiation device 2 is fixed to the conveyor belt 10, and its downwardly disposed injection nozzle 12 faces the coordinate plane of the processing table 4.

In the laser beam irradiation device 2 according to the present invention, a laser beam 19 is generated internally by a laser generator 18, and this laser beam is converged by a lens 20 to become a beam 21.

Note that 22 is a housing with a portion cut out.

The servo motors 7 and 11 are numerical control units of the control device 3! The numerical control device 14 is driven and controlled by an NC (NC) 14, and pattern data to be cut is inputted from a storage device 15 to the numerical control device 14. Based on the signal based on this data, the numerical control device 114 drives and controls the servo motor 7.11 to move the processing table 4 in the vertical direction (X-X direction) and move the laser beam irradiation device 2 in the horizontal direction (Y-Y direction). direction),
The injection nozzle 12 is positioned directly above the coordinates of the cutting position of the interior material 17 placed on the processing table 4.

Further, the numerical control device 14 sends an on-off signal via an on-off switch (on-off switch) 16 to intermittent operation of laser beam irradiation.

The pattern data input to the storage device 15 of the control device 3 is created in the steps shown in the flowchart of FIG.

That is, the coordinates of the original drawing are read using a digitizer,
Convert to digital signal. This signal is input to a computer, and the desired enlargement, deletion, addition, correction, etc. processing is performed using CAD.Then, the obtained information is divided into data, and the desired divided data (cutting drawing) is processed using a plotter. confirm.

Cut line data is created according to the cutting diagram obtained in this way, and after offline teaching, the data of the cutting pattern is output from the computer to the storage device 15.

The interior material 17 to be cut by the above device includes the processing table 4
It can be used from a large area covering almost the entire surface of the mounting surface to one having an appropriate area by positioning and fixing it on the mounting surface, and can be cut by the laser beam irradiation device 2. If available, interior materials of various materials such as sheet materials or tiles can be used.

According to the apparatus having the above configuration, the servo motor 7.11 is driven by the numerical control device 14 based on the cutting pattern data input to the storage device 15, and the injection nozzle 12 is moved to the cutting position. The opening/closing valve 16 opens and the laser beam 21 is ejected from the injection nozzle 12 onto the interior material 17 on the processing table 4, whereby the interior material 17 is cut according to the cutting pattern data.

When cutting the interior material 17 continuously according to the pattern data, the numerical control device 14 continuously sends an on (open) signal to the on-off switch 16, and also continuously sends a signal to the servo motor 7 and/or the servo motor 11. The laser beam 21 may be ejected toward the interior material 17 while the ejection nozzle 12 is moved along the cut line by sending a drive signal.

For example, in the case of batch work in which one pattern is formed using multiple tiles.

After cutting a predetermined pattern in which a set of tiles are arranged on the processing table 4, an off signal is sent to the on-off switch 16 to stop the injection, and then the tiles can be rearranged.

(Effects of the Invention) As is clear from the above description, according to the method of the present invention, interior materials such as tiles can be easily cut into any desired pattern. Therefore, it can be suitably used, for example, not only to form a tile pattern, but also to form an arbitrary pattern over a wide area by combining tiles divided into a plurality of segments.

In addition, because the cutting is precise, there is no waste of material, and if the pattern is the same, it can be repeated mechanically, improving productivity. Moreover, since the cutting is done with a laser beam, there is no dust generated during cutting, and this method has various advantages such as the fact that cutting with a knife does not reduce the sharpness. It is something that you have.
