Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an operating device for starting a memory operation by an NC program or the like in a punch press machine.

[0002]

[Prior art]

 Conventionally, there is a turret punch press machine in which a table 52 is installed in a front portion of a machine body 51 and an operation panel 53 of an NC device is arranged in a rear portion thereof as shown in a plan view of FIG. The operation panel 53 is used for creating an NC program, inputting data for MDI (manual data input) operation, each operation during manual operation, and the like. In addition to an input switch for each data, a press motor start switch 55, an alarm release switch 56, and manual feed operation switches 57 and 58 for the table 52 in the X and Y directions.

In such a punch press machine, the cycle start of the memory operation by the NC program or the like is provided on the front end side surface of the table 52 for the safety of the operator, the convenience of loading the material to the table 52, and the like. In many cases, the start switch 54 is used. In this case, the press motor for driving the flywheel is operated by turning on the flywheel switch 55 of the operation panel 53 in advance before turning on the start switch 54. If the press motor is not rotating when the start switch 54 is turned on, an alarm is issued to stop the machine. In this case, the alarm is released by turning on the alarm release switch 56, and then the flywheel switch 55 and the start switch 54 are sequentially turned on to start the cycle.

[0004]

[Problems to be solved by the device]

 However, if the flywheel switch is forgotten to be turned on at the start operation of the memory operation, the flywheel is returned from the position of the start switch 54 at the front part of the machine body 51 to the position of the operation panel 53 at the rear part of the machine body. The wheel has to be activated, which is troublesome to operate. The distance between them is about 3 to 4 m, but since the auto-loading device etc. is around the punch press machine, the worker cannot stand upright and walk. There are many things that you have to walk to, which is a troublesome task.

An object of the present invention is to provide a punch press capable of restarting operation at a front position without returning to the operation panel when the start operation of the press motor is forgotten and the start switch is operated at the start of the memory operation. A machine operating device is provided.

[0006]

[Means for Solving the Problems]

 The configuration of the present invention will be described with reference to FIG. 1 corresponding to the embodiment. A punch press machine to which this operating device is applied is provided with an operation panel (5) for memory operation and manual operation at the rear part of the machine body (1) and a start switch for memory operation at the front part of the table (4) at the front part of the machine body. Switch (14). Further, there is provided a start processing means (25) which responds to the ON input of the switch (14) and activates the memory operation on condition that the press motor (8) rotates. In such a punch press machine, the start switch of the press motor (8) is provided at the front part of the table (4).

The start switch of the press motor (8) may also be used as the start switch (14). In that case, when the press motor (8) is in a stopped state when the start switch (14) is turned on, it also serves as a switch that issues a start command for the press motor (8) by the next turn on operation of the start switch (14). A processing means (26) is provided.

[0008]

[Action]

 When starting the memory operation, the press motor (8) is normally rotated and the start switch (14) at the front of the table (4) is turned on to start the cycle. If the press motor (8) is not rotating when the start switch (14) is turned on, the press motor starting switch provided at the front part of the table (4) is turned on to turn on the press motor (8). To start. After that, the start switch (14) is turned on to start the memory operation.

In the case of the second aspect, when the press motor (8) is not rotating when the start switch (14) is turned on, the start switch (14) is turned on again. This activates the press motor (8). After that, the memory operation is started by turning on the start switch (4) again.

【Example】

 An embodiment of the present invention will be described with reference to FIGS. This embodiment is applied to a turret punch press. Upper and lower turrets 3, 3 are installed on the frame 2 of the machine body 1, a table 4 is installed in front of the frame 2, and an NC operation panel 5 is installed on the rear side surface. The punch drive mechanism 6 is a crank type having a flywheel 7 and a press motor 8 for driving the flywheel 7, and is installed in the upper frame portion of the frame 2.

The table 4 has a central fixed table 4 a, slide tables 4 b on both sides and a carriage 9. The slide table 4 b moves forward and backward (Y direction) on the rail 11 of the bed 10 together with the carriage 9. Driven. The carriage 9 is provided with a cross slide 12 capable of being fed in the lateral direction (X direction), and a work holder 13 is attached to the cross slide 12. By moving the carriage 9 and the cross slide 12, an arbitrary portion of the plate-shaped work W can be sent to the punch position P. The start switch 14 for memory operation is provided on the side end surface of the carriage 9.

The operation panel 5 is used for creating an NC program, inputting data for MDI operation, each operation during manual operation, etc. In addition to an input switch 15 for each data (FIG. 2), a flyboard is used. It has a wheel switch 16, an alarm release switch 17, manual feed operation switches 18 and 19 in the X and Y directions of the table 4, a CRT display device 20, and the like.

FIG. 1B shows a conceptual configuration of the control system. The PC / NC device 21 is a device for controlling the entire punch press machine 22, and is composed of a CNC device (numerical control device) and a programmable controller. The PC / NC device 21 has a memory operating means 24 for executing the machining program stored in the memory 23, and a start command to the memory operating means 24 is sent by the ON signal of the start switch 14 via the start processing means 25. Given. Operations such as data input of the PC / NC device 21 are performed on the operation panel 5. The start processing means 25 is a means for performing the sequence control shown in FIG. 3, and a switch / combined processing means 26 is configured in some steps (S4) and (S5).

The start operation of the memory operation having the above configuration will be described. Normally, the flywheel switch 16 of the operation panel 5 is turned on, the press motor 8 is rotated, and the start switch 14 at the front of the table 4 is turned on. As a result, the control in the start processing means 25 proceeds from step S1 of FIG. 3 to steps S2 and S6, and the memory operation starts a cycle.

When the start switch 14 is turned on and the flywheel 7 is not rotating, that is, when the press motor 8 is not rotating, the process proceeds from step S2 to S3 in FIG. 3 and an alarm is generated. Stop the machine. When the start switch 14 is in a waiting state for re-operation (S4) and the start switch 14 is turned on in this state, the alarm is released in response to the turning-on operation and the press motor 8 is started. After that, the memory operation is started by turning on the start switch 14 again (S1, S2, S6).

As described above, since the alarm can be released and the press motor 8 can be started by re-operating the start switch 14 on the front portion of the table 4, the start switch 14 is operated without forgetting the start operation of the press motor 8. In this case, the restart operation can be performed at the front position without returning to the operation panel 5. Therefore, the burden on the operator is reduced.

Although the start switch 14 is also used as the start switch of the press motor 8 in the above embodiment, a press motor start switch for releasing the alarm and starting the press motor 8 may be provided side by side with the start switch 14. good.
