Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of exchanging a die for a turret punch press and a device for automatically changing the die,
Especially, the mold exchange control is performed for the mold information that the worker inputs through the interactive input means, the mold information installed in the mold installation station of the turret punch press and the mold information stored in the tool rack. The present invention relates to an interactive management method that accumulates as a database provided in an apparatus and enables die search and die automatic exchange based on this database.

[0002]

2. Description of the Related Art In the case of exchanging dies with a conventional turret punch press, first, the dies described in the NC program are compared with the dies installed in the respective die mounting stations on the turret. In order to do this, manually create a list that can compare the currently installed mold with the mold to be used, and the mold information described in the list is fixedly arranged on the operation panel. Enter using switches and keys. Then, for example, after finishing the machining operation of one NC program or one schedule, the operator pauses the press operation and rotates the turret to check the shape, size, clearance and arrangement angle of the currently installed mold. While checking, the unnecessary mold is taken out from the predetermined station, and the necessary mold is attached and the arrangement angle is adjusted.

[0003]

However, by comparing the dies described in the NC program with the dies installed at the respective die mounting stations on the turret, the dies to be replaced from the turret are selected. To search, workers must manage the molds in the turret and the molds in the tool rack. In addition, when inputting the mold to be used on the operation panel of the automatic mold change control device and editing the mold information, the control switch is fixedly arranged on the operation panel. It was difficult to input and output appropriate information because the operation was complicated and difficult, and sufficient dialogue was not performed. Therefore, it takes a lot of time to manage the mold and input information, resulting in a decrease in operation efficiency of the processing line.

Therefore, in order to solve the above problems, an object of the present invention is to register the mold information in the turret and the mold information in the tool rack as a database in the automatic mold change control device, and the operator Automatically searches for molds and replaces the molds by simply inputting the molds required by the NC program into the mold automatic change control device. Also, a control switch is provided on the operation panel of the mold automatic change control device. It is intended to improve the operating efficiency of the processing line by displaying and allowing the interactive operation of the switch by the interactive information input means.

[0005]

In order to achieve this object, the present invention is a turret punch press for performing punching of a plate material based on the NC program connected to a host controller which provides an NC program, and a die exchange. In the interactive management method of the automatic mold change control device that controls the operation of both mold change devices that perform the operation, the operator inputs the mold information used for plate material processing through the interactive input means, and inputs the information. The mold to be exchanged is searched from the information and the mounted mold information currently mounted in the mold mounting station, and the replaceable mold is searched from the searched information and the housed mold information stored in the housing section. When the molds that can be exchanged are searched for, the molds are replaced by the mold exchanging device, and the mold information that is searched and not searched is displayed.

[0006]

According to the above method and configuration, the operator inputs the die information used for the plate material processing through the interactive input means, and the input information and the attached die information currently attached to the die attaching station. To search for a mold to be exchanged, and to search for a replaceable mold from the search information and the stored mold information stored in the storage unit, and if a replaceable mold is found, The mold is replaced by the mold exchanging device, and the mold information not searched and the mold information not searched are displayed on the processing information display unit.

The tool rack die search unit 97 searches for a suitable die, and the search results are displayed on the CRT.
Display on the screen 53. In step 513, the start button 67 provided on the operation panel 55 is pressed according to the display content shown in FIG. Then, the screen changes to the automatic operation execution screen, and a start lamp (not shown) provided in the start button 67 lights up. In step 515, the tool shuttle 47 replaces the mold according to the screen during automatic operation. FIG. 14 shows a state in which the replacement work for mounting the mold with the mold name TEST1 on the turret station number T107 is being performed. In step 517, the start lamp is turned off in order to inform the worker 25 that the automatic operation is completed. In step 519, it is determined whether or not the mold which cannot be automatically replaced is to be replaced by the worker 25, and when it is replaced, the mold is replaced by the worker 25 (step 521). When the mold replacement by the worker 25 is not performed, that is, when the mold replacement is all performed by the ATC 23, the automatic operation of the mold replacement is completed and the data input screen as shown in FIG. 11 is returned.

By the way, using the ATC control device 1 described above, the mold input by the operator through the touch panel 55 exists in the turret layout information storage unit 91 instead of the tool rack mold storage unit 95. When the designated die mounting station 33 is empty, and when the input die is searched from the turret layout information accumulating section 91 and the tool rack die accumulating section 95 which are currently mounted in the die mounting station 33, the tool is searched. The turret layout information storage unit 91 does not exist in the rack mold storage unit 95, and another mold is mounted in the designated mold mounting station 33 (hereinafter, referred to as automatic turret relayout). An interactive management method of automatic mold exchange will be described.

First, in the automatic turret re-layout, when the die mounting station 33 designated by the NC program 3 is empty, the die used by the ATC 23 is set to the die mounting station 33 designated by the NC program 3. Move to and put on.

In addition, the designated die mounting station 3
If another mold is attached to 3, another mold is AT
After being housed in the tool rack 17 by C 23, the mold to be used is moved and mounted in the designated mold mounting station 33.

As described above, the mold information installed in the upper and lower turrets 29 and 31 and the mold information in the tool rack 17 are registered in the ATC controller 1 as databases 15 and 19, and the worker 25 Only by inputting the mold required by the NC program 3 to the ATC control device 1 via the touch panel 55, the operator 25 can search for the mold to be replaced and replace the mold without managing the mold. It can be done automatically.

The present invention is not limited to the above-described embodiments, but the present invention can be implemented in modes other than the above-mentioned embodiments.

[0035]

As described above, according to the present invention, the mold information mounted in the mold mounting station and the mold information accommodated in the accommodating portion are stored in the mold automatic exchange control device. By registering in the installed mold information storage unit and the stored mold information storage unit, the operator only needs to input the necessary molds in the NC program to the automatic mold replacement control device, and the search and replacement of the molds will be performed automatically. It can be carried out.

Further, by using the interactive input means as the means for inputting the die information, the input can be simplified.

Therefore, it is possible to easily, swiftly and surely perform the die exchanging work of the turret punch press, and it is possible to greatly reduce the working time and improve the productivity.
