Description

The present invention relates to an auxiliary operation device used by being attached to a workpiece processing facility having a large press device.

Conventionally, the operation panel of the press device is, for example, a first operation panel that operates a press operation at a front surface position of the press device body, and a second operation panel that includes switches and displays for performing operations other than the press operation. It is attached to a position that is easy for the operator to visually recognize, for example, the right front surface of the frame of the press device main body, thereby ensuring improvement in workability in the press work. On the other hand, there is a problem that the size of the press device is increased, the device height is increased, and the device width is increased, so that the operator and the second operation panel are separated from each other and the operability is deteriorated. And when peripheral devices, such as a manipulator which carries in and out of a workpiece | work, are provided, since it has to operate through a peripheral device, there exists a problem that operativity worsens further.
Therefore, the first operation panel is provided at the front surface position of the press apparatus main body, and the second operation panel can be remotely operated by light, radio waves, ultrasonic waves, etc. In addition to improving operability, a space for mounting peripheral devices is also secured (see, for example, Patent Document 1).

However, in the device described in Patent Document 1, since only the second operation panel can be remotely operated, the press operation of the press device needs to be performed using the first operation panel provided at the front surface position of the press device body. The working position of the operator is limited to the front area of the press device main body. For this reason, in a work processing facility having a large press device, the place where the press work is performed and the work fixed position of the operator are far apart, and there is a situation where details of the work state of the work cannot be grasped at the time of processing. Furthermore, in addition to the operation of the press device, it is also necessary to simultaneously operate peripheral devices such as a manipulator that loads and unloads workpieces, a workpiece moving table that loads and moves workpieces, etc. Limited by the operation of the device.

For this reason, there is a need for a portable operation panel that can operate the press device and peripheral devices even when the operator leaves the work fixed position so that the details of the work condition of the workpiece can be grasped at the time of machining. Here, in the work processing facility, the operation of the press device and peripheral devices are performed in a coordinated manner, so the number of control elements increases, and a portable operation panel is required to reliably perform complex operations remotely while ensuring reliability. It is considered effective to use a wired system.
However, in the wired system, the length and weight of the signal cable connecting the portable operation panel and the main body side of the work processing equipment, there are restrictions on the range and work time in which the operator can move the portable operation panel, Furthermore, there is a problem that troubles such as disconnection of the signal cable also occur.

Next, a method of using the auxiliary operation device 10 according to an embodiment of the present invention will be described.
First, the power-on switch 30 of the operation panel 20 is turned on, and power supply to the press device 13, the work conveying means 16, the left and right manipulators 17 and 18, the main control panel 19, and the operation panel 20 is started. Further, by operating the signal changeover switch 65 of the input signal selection means 66 of the operation panel 20, for example, the first opening / closing part 63 provided in the signal output cable 35 is opened, and the second opening provided in the data transmission cable 61. The opening / closing part 64 is closed. As a result, only the operation signal from the fixed control panel 23 is input to the main control panel 19, and the work processing equipment 21 can be operated by the portable operation panel 25.

Next, the power switch 50 of the portable operation panel 25 is turned on so that the portable operation panel 25 can be operated. Here, the remaining amount of the battery 47 used in the portable operation panel 25 can be confirmed by the battery monitor 57. Further, the communication monitor 56 can confirm the communication state between the wireless receiver 22 provided on the fixed control panel 23 and the wireless transmitter 24 provided on the portable operation panel 25. Further, on the touch panel 33 of the operation panel 20, output signals corresponding to the driving conditions of the press device 13, the work conveying means 16, and the left and right manipulators 17 and 18 are input / output unit 37 and arithmetic processing unit of the main control panel 19. 36 and the signal input cable 39, the display of the touch panel 33 displays the operating status of the press device 13, the work conveying means 16, and the left and right manipulators 17 and 18. For this reason, when the workpiece transfer means 16 is not present at the standby position, the two safety switches 49 are activated to make the table out switch 43 operable, and the table transfer switch 43 is operated to operate the workpiece transfer means. 16 is moved to the standby position.

Then, the two safety switches 49 are actuated so that the operation switches 44 and 45 of the left and right manipulators 17 and 18 are operable, and the operation switches 44 and 45 are operated to transfer the work conveyed by the work conveyance line. 12 is taken out of the work transfer line using the left and right manipulators 17 and 18 and placed on the lower mold 14 attached to the work placing table 15 of the work transfer means 16 at the standby position. Subsequently, the workpiece transfer means 16 holding the lower mold 14 on which the workpiece 12 is placed is moved to the press working position by operating the table-in switch 42 while operating the two safety switches 49.
Next, the press operation switch 41 is operated while operating the two safety switches 49, the elevating unit 27 is lowered, and the upper die 11 starts to press the workpiece 12.

Next, while operating the two safety switches 49, the table out switch 43 is operated to move the workpiece transfer means 16 from the press working position to the standby position. Further, the two safety switches 49 are operated to operate the operation switches 44 and 45 of the left and right manipulators 17 and 18, and the workpiece 12 after press working placed on the lower mold 14 of the workpiece placing table 15. Is taken out from the work conveying means 16 and paid out to the work conveying line. Thereby, the press work of one work 12 is completed. Then, by operating the two safety switches 49 and operating the operation switches 44 and 45 of the left and right manipulators 17 and 18, another work that has been transported by the work transport line is moved to the left and right manipulators 17 and 18. The next press work can be started by taking out from the workpiece transfer line and placing it on the lower mold 14 attached to the workpiece mounting table 15 of the workpiece transfer means 16 at the standby position.

Further, the fixed control panel is configured to be connected to the main control panel by wire, but the fixed control panel may be connected to the operation panel by wire. In addition, the press operation switch, table in switch, table out switch, and left and right manipulator operation switches cannot be activated unless both safety switches are activated. The operation of any one of the safety switches may make the switches operable. Although loading and unloading of workpieces is performed on one workpiece conveyance line, loading and unloading may be performed separately by providing a workpiece loading line and a workpiece unloading line.
Furthermore, in the usage method of the auxiliary operation device, the signal changeover switch of the input signal selection means is operated to enable the operation of the workpiece processing equipment only by the portable operation panel, but the first and second opening / closing parts are closed.
