Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to metal, plastic,
The present invention relates to a laser processing system for performing desired laser processing on a sheet-shaped material such as a film or paper, and particularly to a laser processing system for performing different laser processing on a large number of sheets.

[0002]

2. Description of the Related Art Conventionally, in the laser processing of all sheet materials such as metal, plastic, paper and label, laser processing equipment is directly operated to perform different laser processing such as punching and cutting for each material. . In recent years, complicated processing such as drilling and cutting has become possible, and the operation itself has become complicated.

[0003]

Further, in the case where a large number of complicated different processes are performed on various specified materials or a plurality of individualized materials in advance for request or distribution, the processing work is performed. It requires a lot of time and labor, and a rapid laser processing cannot be performed. An object of the present invention is to provide a laser processing system suitable for a laser processing process in which complicated and different processing is performed on a large number of these specified materials or a plurality of individualized materials.

[0004]

In order to solve the above-mentioned problems, a laser processing system of the present invention is a laser processing system for irradiating a sheet with a laser beam by a laser beam irradiation device to perform laser processing on the sheet, A laser processing storage unit that stores the code data attached to each sheet and the processing content for performing laser processing corresponding to each code data, the code reading unit that reads the code data attached to each sheet, and the read code data It is provided with a searching means for searching the corresponding laser processing contents from the laser processing storage means, and a control means for controlling the laser light irradiation device based on the search result of this searching means and performing laser processing on the corresponding sheet. .

[0005]

The code data attached to each sheet is read in advance, the laser processing content corresponding to the read code data is searched from the laser processing storage means, and the control means controls the laser light irradiation device based on the search result. Laser processing is automatically performed on the corresponding sheet.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on preferred embodiments. FIG. 1 is an overall explanatory view of a laser processing system of the present invention, FIG. 2 is an explanatory view of a processed sheet for laser processing, and FIG. 3 is an explanatory view of a state in which the sheet is processed.

The laser processing system 1 shown in FIG.
The sheet S is fed to the processing table 3 while the sheet feeding means 2 of FIG. Then, the code data is read by the code reading means 4. This code data is sent to the control unit 5. On the other hand, in the storage unit 6 connected to the control unit 5,
The processing contents are supplied and stored from a recording medium such as the floppy disk 7 as coded data for each sheet, and the processing contents corresponding to the read code data can be searched.

The sheet S placed on the processing table 3 is processed by the laser beam irradiation device 10. The laser beam irradiation device 10 has a laser oscillator 12 and a laser beam for irradiating the sheet. An appropriate optical system, total reflection mirror 13,
Although not shown, the convex cylindrical lens 14 and the like can two-dimensionally irradiate the sheet with laser light by an irradiation system such as a conventionally known plotter type, polygon mirror, or scan mirror.
1 is controlled by the control unit 5.

Reference numeral 8 is an operation section for operating the laser processing system 1, and 9 is a display section for displaying a processing state of the laser processing system 1.

Next, the procedure of processing the sheet S will be described.
As shown in FIG. 2, when the individual information 16 is printed in advance by a printer or the like, the sheet S on which the code data 15 is printed is set in the laser processing system 1 at the same time.
Code data 15 read by the code reading means 4
The corresponding processing content is retrieved from the laser processing storage means 6. When the processing content is hit, the control unit 5 controls the laser light irradiation device 10 based on the processing content to process the sheet S on the processing table. In FIG. 3, a notch 17 and a perforation 18 are formed based on the processing content.

There are various processing contents such as slits, sewing machines, and half-cuts for labels. Further, the sheet to be processed is not limited to a single piece and may be a continuous sheet.

[0012]

As described above, the laser processing system of the present invention reads the code data attached to each sheet in advance and retrieves the laser processing content corresponding to the read code data from the laser processing storage means. Based on the search result, the control means controls the laser light irradiation device to automatically perform laser processing on the corresponding sheet, so that an excellent processing effect can be obtained.
