In order to partially irradiate the surface of the fabric with the laser beam, the laser irradiation device selectively emits the laser beam and the laser beam from the laser irradiation device is changed by changing the refraction angle of the laser beam. A refraction angle changing element or the like for turning on / off the firing must be incorporated.
However, special techniques are required for this purpose, and it is difficult to easily incorporate a selective emission calculation element, an on / off oscillation element, a refraction angle changing element, and the like into an existing laser irradiation apparatus.

  Therefore, an object of the present invention is to apply an existing pattern drawing device to a laser irradiation device and draw a pattern on a fabric surface simply by a laser beam.

  In the method for producing a pattern drawing fabric according to the present invention, the laser irradiation device 11 irradiates the fabric 12 with a laser beam, and in the laser pattern drawing step of drawing the pattern on the fabric with the laser beam, the laser irradiation device 11 applies the cloth 12. The first feature is that an obstacle is selectively acted on the straight path 14 of the incoming laser beam 13 to prevent the laser beam 13 from going straight, and a pattern is drawn on the fabric 12 depending on the presence or absence of the action of the obstacle. .

  A second feature of the method for producing a pattern drawing fabric according to the present invention is that, in addition to the first feature, an obstacle that prevents the laser beam 13 from going straight is provided on the rotating peripheral surface 17 of the rotating member 16. The projection piece 81 is configured so that the rotating body 16 is rotationally driven to cause the projection piece 81 to appear and disappear in the straight path 14 of the laser beam 13.

As described above, it is well known to draw a pattern on the fabric surface in a field other than the laser beam irradiation technique.
According to the present invention, the laser beam irradiation apparatus does not incorporate a pattern drawing apparatus known in other technical fields, but continues to irradiate the laser beam from the laser beam irradiation apparatus in the laser pattern drawing process. In the laser pattern drawing process of drawing the image, the obstacle is selectively acted on the straight path 14 of the laser beam 13 from the laser irradiation device 11 to the fabric 12, and the pattern is drawn by preventing the laser beam 13 from going straight. Therefore, it does not require specialized technology related to laser irradiation equipment such as a laser beam selective launch calculation element or a refraction angle changing element that changes the laser beam refraction angle to turn on / off the laser beam emission from the laser irradiation equipment. Easily draw a pattern on the fabric surface with a laser beam Theft is possible.

  In the present invention, the laser beam is intermittently emitted from the laser beam irradiation device by a laser beam selective emission calculation element or a refraction angle changing element that changes the refraction angle of the laser beam to turn on / off the emission of the laser beam from the laser irradiation device. Since the laser beam is continuously irradiated from the laser beam irradiation device in the laser pattern drawing step, it is difficult for the amount of laser beam irradiation to vary, and a pattern drawing fabric without pattern distortion can be obtained.

  The laser beam irradiation apparatus that continues to irradiate a laser beam in the laser picture drawing step can be used for any of the oscillation methods of continuous oscillation and pulse oscillation.

The projecting piece 81 is screwed to the head.
When the rotating body 16 rotates, the protruding piece 81 protruding from the rotating peripheral surface 17 protrudes into the straight path 14 of the laser beam like an adjustment cam, and the laser beam 13 is blocked by the protruding piece 81 and is the fabric 12. On the surface of the fabric 12, a shadow image 18 formed by the laser beam being blocked by the projection piece 81 is drawn.

In FIG. 2, an obstacle that prevents the laser beam 13 from moving straight is constituted by a parallel moving body 82 that translates with respect to the fabric 12, and the moving body 82 is provided with a transmission gap 21 through which the laser beam 13 can pass. A laser pattern drawing device is shown that draws a pattern by irradiating the fabric 12 with the laser beam 13 depending on whether or not the transmission gap 21 moves parallel to the cloth 12 and crosses the straight path 14 of the laser beam 13.
When the movable body 82 is driven to reciprocate in the width direction of the fabric 12 in the process in which the fabric 12 passes under the laser pattern drawing device at a constant speed, the transmission gap 21 also reciprocates in the width direction of the fabric 12.

The eaves 32 are pushed out, and the protruding and protruding pieces 83 are protruded into the straight path 14 of the laser beam 13. Therefore, in the laser pattern drawing device shown in FIG. 3, the protruding / depressing piece 83 mounted on the piston rod 32 of the air cylinder 31 to which compressed air is not sent is retracted from the straight path 14 of the laser beam 13 and is The laser beam 13 is applied to the surface of the fabric 12 in the retracted and retracted portion 37 of the retracted piece 83, and a picture corresponding to the appearing and retracting of the retracted piece 83 is drawn.

In FIG. 5, a plurality of nozzles 41 for selectively injecting a fluid 84 toward the straight path 14 of the laser beam 13 are arranged in a straight line parallel to the fabric 12 and are ejected from the plurality of nozzles. A laser picture drawing apparatus that selectively ejects the fluid 84 from each of the plurality of nozzles 41 is illustrated as an obstacle that prevents the fluid 84 from traveling straight.
Each of the plurality of nozzles 41 is opened and closed by a valve that is restricted by restriction, similarly to the valve 34 shown in FIG.
