BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing system in which a transfer machine having a plurality of processing machines is centrally controlled by numerical control or the like, and in particular, a support for supporting a sub-control panel installed in each processing machine. Regarding the mechanism.

[0002]

2. Description of the Related Art In a processing line for processing multiple processes and various types of workpieces, a plurality of processing machines such as transfer machines are arranged according to the number of processes. In such a processing system, as shown in FIG. 8, a plurality of processing machines A, B,
Main control panel (including operation panel) M that controls the whole of C and D
And sub-control panels (including an operation panel) (a), (b), (c), and (d) provided corresponding to the respective processing machines. In this processing system, numerical control is performed, and a programmed sequence command is issued from the main control panel M to each sub-control panel. The sub-control panels provided for the respective processing machines control the motors of the respective processing machines based on the sequence command from the main control panel.
Therefore, the sub control panel is integrated with a sequence control section, a motor control section that performs motor control according to feedback from the motor, and an operation panel. According to the method of separately arranging the main control panel and the sub control panel in this manner, it is possible to prevent the main control panel from being enlarged, and to provide a motor control unit and the like for each processing machine. There are advantages such as reducing the possibility of noise on the route and minimizing the wiring extending from the main control panel.

[0003]

The processing system such as a transfer machine that having a plurality of processing machines as described above [invention is to solve the above, for increasing the transfer efficiency work sent a short distance between each step, or in a factory Due to space restrictions, it is necessary to arrange the processing machines closely. However, the sub-control panels (a), (b), (c), and (d) provided corresponding to each processing machine include many control units and operation panels as described above. , Its weight is very large, about 100 kg, and its external dimensions are also large. Therefore, it is difficult to suspend the pendant from the processing machine as in a conventional small operation panel. Therefore, it is necessary to install this kind of sub-control panel on a support base. For example, when the sub-control panel is installed on a support table arranged on the side of the processing machine, the sub-control panel is arranged between the processing machines densely arranged, which hinders the work. In addition, when the sub-control panel is installed above the processing machine, not only does the structure for supporting the sub-control panel become large, but also the position of the sub-control panel becomes too high, making it difficult to operate. . Further, there is a problem that the sub-control panel hinders the work during maintenance of the processing machine.
The present invention solves the above-mentioned conventional problems. Even when a plurality of processing machines are densely arranged, the sub-control panel provided for each processing machine can be operated without disturbing the operation and operating. It is an object of the present invention to provide a support mechanism for a sub-control panel in a processing machine, which can be arranged in a place where it is easy to operate, and can be installed in a state where there is no obstacle to maintenance of a motor of the processing machine.

[0004]

According to the present invention, a supporting mechanism for a sub-control panel in a processing machine according to the present invention comprises a plurality of processing machines provided with a motor for feeding a moving table supporting a processing head to a work supporting portion; the motor arrangement is provided corresponding to the main box and this is connected to the main control board and the respective processing machine for controlling the entire plurality of processing machines
In a machining system having a sub-control panel for controlling another motor , the sub-control panel is supported on a support stand located on a side of the motor of the processing machine, and is above the motor. And a connecting mechanism between the support base and the sub-control panel is provided with a rotation mechanism for rotating the sub-control panel to a position outside the upper region of the motor. .

[0005]

In the above means, the sub-control panel for controlling each processing machine is disposed above the moving table feed motor of the processing machine. This position does not require any special horizontal space for the sub-control panel installation, is relatively low, does not require a large support mechanism, and operates the operation unit provided on the sub-control panel. It becomes easy height. In addition, since the sub-control panel can be rotated to a position where the sub-control panel is removed from the upper region of the motor by the rotation mechanism provided on the support base, maintenance of the motor and the like can be easily performed.
