Abstract

PROBLEM TO BE SOLVED: To detect the abnormality of a data bank and to prevent the trouble by checking a die number with the number allocated to die data selected and taken out, varidating the die data only in the case of coincidence of both and transferring the die data to a press control circuit. SOLUTION: For example, the mold No.50 is selected, and at the time of pushing a start button 13, the No.50 data in a data bank memory is downloaded into a temporary storing memory with a data change-over signal from the press machine control circuit 12. Successively, in the case the member allocated to the data download into the temporary storing memory is No.50, the die data are transferred to the press machine control circuit 12, and the adjustment and the change of slide adjustment in the press machine are started. If the number allocated to the die data downloaded into the temporary storing memory is not No.50, since it is considered that the data bank memory is not normal, the abnormality is displayed and the die data are not transferred to the press machine control circuit 12.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data bank device for a press machine. A data bank device presses data that needs to be adjusted or changed in accordance with the specifications of the press machine and the specifications of the feeder that match the mold used, such as the die height of the press machine and the inner width of the feed bar. A series of devices that store in advance in the control device built into the machine, transfer the data corresponding to the mold to the control circuit of the press machine at the time of automatic mold change, and automatically set up the operating conditions of the press machine Means

[0002]

2. Description of the Related Art Conventionally, many such devices have been disclosed. For example, JP-A-3-99730, JP-A-7-12
4796 can be mentioned.

[0003]

In the case where a data storage device is not downloaded due to a failure caused by external noise or a defective element itself, for example, if a type to be used is not downloaded to another type, An accident can occur if data is downloaded. An object of the present invention is to provide a data bank device for a press machine that prevents such an accident.

[0004]

In the present invention, the type number of the type to be used is compared with the number assigned to the selected and extracted type data, and the type data is validated only when they match.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG.
Is connected to a press machine control circuit, and the press machine control circuit 12 is connected to a start button 13. The press machine control circuit 12 is a circuit for controlling the entire press machine, and also controls various motors such as the slide adjusting motor 14.

The data switching signal 2 is sent from the press machine control circuit 12 to the data bank 1, and the data link signal 3 for mold data is sent from the data bank 1 to the press machine control circuit 12.
Is sent.

[0007] The start button 13 is a button pressed by an operator when starting the work of changing the mold.

FIG. 2 shows a data bank 1.
The data bank 1 includes a main control unit 4, a model number input switch 5, a data input numeric keypad 6, and a type setting display 7 connected thereto.

The model number input switch 5 is a switch for inputting a number determined for each type in order to select a type to be used, that is, a selection input switch.

A data input numeric keypad 6 is a key for inputting data for each type, that is, a setting input key for setting specifications of a press machine, specifications of a material supply device, and the like when using the type.

The type setting display 7 is a display for inputting the data applied to the type number and the type and for confirming the data after the input.

The main control section 4 connects the CPU to various memories and various ports to perform data processing.

FIG. 3 shows an image of the processing of the data.

A large number of type data are stored in the data bank memory. This type data is, for example, the specifications of the press machine as described above, and is given a number for data confirmation. This data confirmation number is automatically assigned by the program of the CPU according to the storage location of the mold data.

Here, the case of using the model of the model number 50 will be described as an example. When the model number 50 is selected and the start button 13 is pressed, the data at the address 50 in the data bank memory is downloaded to the temporary storage memory by the data switching signal from the press machine control circuit 12.

Next, if the number assigned to the data downloaded to the temporary storage memory is 50, the mold data is transferred to the press machine control circuit 12, and adjustment and change such as slide adjustment of the press machine are started. You.

If the number assigned to the mold data downloaded to the temporary storage memory is not 50, it is considered that the data bank memory is not normal, so that an error is displayed and the mold data is transferred to the press machine control circuit 12. Not done.

[0018]

According to the present invention, an abnormality in data in a data bank can be detected, thereby preventing an accident.
