Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cantilever type laser beam machine, and more particularly to a cantilever type laser beam machine in which a laser beam machining head is provided in a main frame in a cantilever type so as to be movable in all axial directions.

[0002]

2. Description of the Related Art A cantilever type laser processing machine is known in which a laser processing head is provided in a main body frame in a cantilever form so as to be movable in all axial directions of an X axis, a Y axis and a Z axis.

In this cantilever type laser processing machine, various processing tables and jigs suitable for the shape of the workpiece are exchangeably arranged at the laser processing position by the laser processing head, so that not only the flat plate but also the pipe is processed. In the case of a three-dimensional laser processing head that can perform laser processing for cutting or welding of a three-dimensional shaped work such as a right-angled box, and the laser processing head can tilt and tilt, a free-form three-dimensional object Laser processing is also possible and it has excellent versatility.

Further, in the cantilever type laser processing machine, two processing tables are provided movably between a laser processing position by a laser processing head and a workpiece loading / unloading position apart from the laser processing position. By alternately using two processing tables, it is possible to carry in and out the workpieces, set up and sort the products on the other processing table during laser processing using one processing table. There is something.

In the cantilever type laser processing machine which uses the two processing tables in exchange, the processing table can be moved to the left and right sides from the laser processing position, and the workpiece loading and unloading positions are provided on the left and right sides of the laser processing position. And the processing table is provided so as to be movable only on one side of the laser processing position, for example, on the right side, and the processing table is replaced by moving the processing table in the front-back direction at the right side moving position. In some cases, the processing table is provided so as to be vertically movable in three dimensions, and the processing table is replaced by the three-dimensional movement of the processing table.

[0006] Generally, in a cantilever type laser beam machine, an operation panel is arranged on the outer surface of one end of the main body frame, and the operation position of this operation panel is, for example, the right end outside the processing area. Further, when a protective cabin that surrounds the processing area is installed, the operation position of the operation panel is outside the protective cabin.

Further, in the long machine and the laser processing machine for large plate processing, the processing machine itself travels on a rail, and the work is fixed on a fixed processing table for processing.

[0008]

In the cantilever type laser processing machine, various products can be processed by preparing various processing tables and jigs suitable for the shape of the workpiece, but not yet. The processing table used and the storage space for the jig must be secured, and a large space is required as a whole. Further, it takes time and labor to exchange the processing table and the jig, which causes a decrease in the operating rate of the cantilever type laser processing machine.

Further, in an all-axis optical movement type cantilever type laser processing machine in which the laser processing head can move in all axial directions, the processing table is fixed during laser processing and the laser processing head moves axially with respect to the processing table. By doing so, all processing positions are determined, so the machinable area is determined by the maximum axial movement stroke of the laser processing head, and to expand the machinable area, the maximum axial movement stroke of the laser processing head must be increased. The cantilever type laser processing machine itself becomes larger.

Further, the cantilever type laser processing machine configured to exchange and use two processing tables is excellent in productivity, but the workpiece loading / unloading position with respect to each processing table is provided on the left and right sides of the laser processing position. Once provided,
The installation space for the processing table is 3 times the installation space for one processing table. Further, since the workpiece loading and unloading positions are separated on the left and right sides of the laser processing position, workability of loading and unloading the workpiece decreases, and it becomes necessary to install two workpiece loading and unloading lines on the left and right.

In addition, in the case where the processing tables are exchanged by moving the processing tables in the front-rear direction, the workpiece carry-in / out position is not divided into two, but in this case as well, the installation space of the processing table is small. It requires three times the installation space of one processing table, which makes the replacement movement system of the processing table complicated.

Further, when the processing table is exchanged for use by moving the processing table three-dimensionally, the installation space of the processing table may be twice the installation space of one processing table, but the installation space of the processing table is large. The exchange transfer system becomes complicated and large-scale.

Further, in the conventional cantilever type laser beam machine, since the operation panel is arranged on the outer side surface portion of one end of the main body frame, the operation area of the operation area of the operation panel is changed. There is a blind spot in part and the operability is poor. On the other hand, it is conceivable to separate the operation panel from the main body frame and place the operation panel separately, but in this case external wiring is required between the operation panel and the main body frame, and the installation position of the operation panel is The work area may be separated from the processing area, which may reduce the operability. In addition, the arrangement of the operation panel is limited by the space required for loading and unloading the workpiece with respect to the processing area, and when the protective cabin is installed, these problems become more prominent. Further, in both cases, since the operation panel is arranged outside the main body frame, an installation space for the operation panel and an operation space are required in addition to the arrangement space for the main body frame.

In the long machine and the laser processing machine for large plates, since the work is fixed and processed, the processing dust and dross and the processed piece are left around the work, and the working environment is bad. Further, when processing a large number of small workpieces, the laser processing machine itself is moved, so that high speed processing is not possible.

The present invention has been made by paying attention to the above-mentioned problems, and by efficiently utilizing the space, various processing tables and jigs can be efficiently exchanged and used, and the laser processing head can be used. It is possible to expand the workable area without increasing the maximum axis movement stroke of the machine, and it is possible to carry in and out the work piece on the other machining table during laser machining using one machining table. The purpose of the invention is to provide a cantilever type laser processing machine in which an operation panel is installed in a position with good operability without causing blind spots in the work area, the working environment is further improved, and a large number of small objects can be picked up at high speed. I am trying.
