Abstract

PROBLEM TO BE SOLVED: To prevent a work from deforming or buckling in the case of working a large-sized work and to prevent a product and a machine from damaging by providing a remaining frame support means to support one end side of a remaining frame which is supported on a table upper face by being projectingly operated when inclining a work chute to separate a machined work from the remaining frame and to take out the work. SOLUTION: After a plate material supported onto a table upper face is machined at a machining part 2, by inclining a work chute 14, a work separated from a remaining frame is taken out by the work chute 14. When inclining the work chute 14, one end side of the remaining frame supported to the table upper face is supported by remaining frame support devices 22, 22'. By this method, the possibility that the remaining frame losing toughness is subjected to drooping, deforming, buckling, etc., is avoided. Plural remaining frame support devices 22, 22' are provided corresponding to the size of the remaining frame, and a means for retractably operating each of remaining frame support devices 22, 22' is provided.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work unloading apparatus and a work unloading method for a plate processing machine such as a punching machine, a thermal cutting machine, and a combined punch and thermal cutting machine.

[0002]

2. Description of the Related Art Conventionally, in this type of sheet material processing machine,
For example, as disclosed in Japanese Patent Application Laid-Open No. 10-29021, a shooter table (work shooter) is provided in the vicinity of a processing section in order to carry out a processed work (product), and the work shooter is used for processing the work. Later, the actuator is tilted by the operation of the actuator, and the work is slid on the work shooter to be carried out of the machine body.

In recent years, there has been an increasing demand for processing larger products by using the above-mentioned plate material processing machine, and accordingly, the necessity of increasing the size of the work shooter has been increasing. Further, in the case of a machine that processes a plate material while moving the processing section in one direction, it is necessary to prepare a work shooter having a length corresponding to the movement stroke of the processing section.

[0004]

However, when handling a large-sized work by increasing the area of the work shooter as described above, the work shooter is tilted to separate the processed work from the remaining frame and carry it out. At this time, since the remaining frame is in a cantilevered state, there is a problem that the left frame breaks down, which causes damage to products and machines.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and it is an object of the present invention to prevent deformation and breakage of a workpiece even when machining a large-sized workpiece, thereby preventing damage to products and machines. It is an object of the present invention to provide a work unloading device and a work unloading method in a plate material processing machine capable of performing the following.

[0006]

In order to achieve the above object, a work unloading device in a plate processing machine according to a first aspect of the present invention includes a processing section for processing a plate supported on a table upper surface, and a processing section for processing the plate. A work unloading device in a plate material processing machine including a tiltable work shooter that separates and unloads a work processed by a part from a remaining frame, the protrusion operation being performed when the work shooter is tilted, and supported by the table upper surface. And a frame supporting means for supporting one end of the remaining frame.

In the first invention, after the plate supported on the table upper surface is processed by the processing section, the work shooter is tilted and moved, and the work separated from the remaining frame is carried out by the work shooter. Then, when the work shooter is tilted and moved, one end of the remaining frame supported on the upper surface of the table is supported by the remaining frame supporting means, so that the remaining frame having no rigidity may be deformed. In addition, the occurrence of breakage of the waist and the like can be avoided. Therefore, it is possible to reliably prevent a product or a machine from being damaged due to dripping of the remaining frame when the work is carried out.

In the present invention, it is preferable that a plurality of the remaining frame supporting means are provided in accordance with the size of the remaining frame, and that a retracting control means for selectively operating each of the remaining frame supporting means is provided. In this way, an appropriate remaining frame supporting means which does not interfere with the work to be carried out is selectively operated depending on the size of the remaining frame, in other words, the size of the plate material to be processed, and is left at an appropriate position. Since one end of the frame can be supported, deformation of the remaining frame can be more reliably prevented.

Further, the remaining frame supporting means may be freely protruded and retractable in a substantially horizontal direction with respect to the table upper surface.
Alternatively, it may be made to be able to come and go in a direction substantially perpendicular to the table upper surface.

Next, a work unloading method in a plate processing machine according to a second aspect of the present invention is a work part for processing a plate material supported on a table upper surface, and a tilting work for separating the work processed by the work part from a remaining frame and discharging the work. A work unloading method in a plate processing machine having a flexible work shooter,
When the work shooter is tilted, the remaining frame supporting means is operated to protrude to support one end side of the remaining frame supported on the table upper surface.

In the second invention, as in the first invention, when the work shooter is tilted, one end of the remaining frame supported on the upper surface of the table is supported by the remaining frame supporting means. In addition, it is possible to prevent the remaining frame, which has lost rigidity, from dropping and deforming, and the occurrence of breakage of the waist and the like. Therefore, it is possible to reliably prevent a product or a machine from being damaged due to dripping of the remaining frame when the work is carried out.

In the second invention, a plurality of the remaining frame supporting means are provided corresponding to the size of the remaining frame, and the remaining frame supporting means is provided based on information on the size and the position of the remaining frame. It is determined whether or not to operate, and when it is to be operated, which remaining frame supporting means is to be activated is determined. Based on this determination, the remaining frame supporting means performs a required operation to carry out the work. Preferably. In the configuration as described above, based on the size of the remaining frame, in other words, the size and the information on the position of the plate material to be processed,
It is determined whether or not the remaining frame is large enough to operate the remaining frame support means (whether there is a risk of dropping) and
When operating the remaining frame support means, it is determined which of the plurality of remaining frame support means should be operated, and based on the determination result, the operation or non-operation of the remaining frame support means, or In operation, the required remaining frame supporting means is operated to support the remaining frame, and the work is carried out in this supported state. In this way, it is possible to always appropriately control the remaining frame support means to prevent damage to the workpiece and the machine due to deformation of the remaining frame.
