JPS61286086A - Laser cutting equipment with flue gas deodorizer - Google Patents

Abstract

PURPOSE:To remove the gas generating at laser cutting time on the upper and down of a cutting sheet and to reduce the environmental pollution by providing to the laser cutting head as well the suction box for flue gas deodorizing provided at the lower part of the cutting table. CONSTITUTION:A suction box 3c is set up at the lower part of a cutting table 2a and the suction box 3c' is provided also on a laser cutting head 2c as well. The suction box 3c' is located therefore at the upper part of the cutting part of a cutting sheet material 1 together with the laser cutting head 2c and linked to a flue gas deodorizer 3a by a duct hose 3b. And the suction box 3c is linked to the flue gas deodorizer 3a by the duct hose 3b as well and the gas generating at the laser cutting time is removed.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a laser cutting device, particularly an exhaust system having a function of exhausting smoke generated during laser cutting.[Prior Art] Generally, sheet materials are cut on a cutting table. In a laser cutting device, especially when equipped with an exhaust gas deodorizer for deodorizing exhaust gas during laser cutting, the exhaust gas deodorizer is conventionally installed under the cutting table to operate the exhaust gas deodorizer.

[Problem that the invention seeks to solve]

As mentioned above, conventional laser cutting equipment with an exhaust gas deodorizer has the exhaust smoke deodorizer installed at the bottom of the cutting table.
Therefore, if smoke rises above the sheet material to be cut during laser cutting, it cannot be exhausted and pollutes the environment.

[Means for solving problems]

The present invention has been developed with the above-mentioned points in mind, and includes an exhaust gas deodorizing intake box in an exhaust gas deodorizing device l, which is provided both at the lower part of the cutting table and at the laser cutting head.

[Effect]

21+) By installing an intake box for exhaust gas deodorization with 9 S S crotch 16 1 h 5 ° τ lie L and 2 buttons, smoke generated during laser cutting can be directed upward and downward of the sheet material to be cut and around the laser cutting head. can be evacuated.

〔Example〕

FIG. 1 shows the main structure of an embodiment according to the present invention, in which 1 indicates a sheet material to be cut, ? 3 is a laser cutting device, and 3 is an exhaust gas deodorizing device. Since the laser cutting device 2 is commonly used, a description of its main components and functions will be omitted, and only the cutting table 2a, Y cursor and laser cutting head 2C are shown here. Further, the flue gas deodorizer 3 includes a flue gas deodorizer section 3a, a duct hose 3b, and intake boxes 3c and 38.

That is, in the laser cutting apparatus with an exhaust gas deodorizer shown in FIG. 1, an intake box 3C is installed under the cutting table, and an intake box 3c' is also installed on the laser cutting head 2C.

Here, in the exhaust gas deodorizer section, the intake box 3J
is always located above the cut portion of the sheet material 1 to be cut together with the laser cutting head 2C, and this intake box 3c' is connected to the exhaust gas deodorizer section 3a by a duct hose 3b. Note that it is clear that the intake box 3c can also perform its function by being connected to the exhaust gas deodorizer section 3a through the duct hose 3b.

〔Effect of the invention〕

As explained above, according to the present invention, the simple structure in which the exhaust gas deodorizing intake box is installed at the bottom of the cutting table and the exhaust gas deodorizing intake box is also installed on the laser cutting head, makes it possible to It is possible to provide a device that can significantly remove generated smoke and reduce environmental pollution.

Furthermore, as an additional effect of such a configuration, the exhaust gas deodorizing intake box can always be positioned above the laser cutting part, and it is possible to prevent the reflected light of the laser beam from the cutting table from being scattered to the outside.
