1 to 12 show an embodiment of a feed monitor device for a transfer press line according to the present invention. FIG. 1 shows a configuration of a feed monitor device 1 according to the present invention. The configuration includes a CPU 2 for inputting required data, performing calculations, comparisons, and the like, and outputting required data to required locations, and a ROM 3 and a RAM 4 for storing data.
A keyboard 5 for setting and inputting data; a display 6 for displaying required data; a line driver / receiver 7 for adjusting data input / output levels between the keyboard 5 and the display 6 and the CPU 2; It comprises an I / O port 8 connected to input and output of data with each unit.

[0010] The I / O port 8 is connected to an input / output with a transfer press line. The transfer press line is, for example, a material supply device 9 shown in FIGS.
Press machine 1P, 2P, between
.. Are arranged at required intervals, and a required stage, an idle stage Id, a press working stage (1P,...) Are provided above and between these, and a transfer 1 is provided.
0 from the stage Ido of the material supply device 9 to the final idle stage I by the clamper 11 provided on the feed bar 10A.
The work is transported to de sequentially. FIG. 11 shows a press machine 1
If there is no idle stage Id between P, 2P,..., FIG. 12 shows a plurality of press working stages 1P, 1P, 1P provided on the press machine P, and an idle stage Id provided between the press machines P, Further, among the idle stages Id, required ones Idt which move in the feed direction are provided.

The connection to the I / O port will be described in order. The work detection input is an input when a work detector 11A provided in each of the clampers 11 detects a work, and there are as many as the number of the clampers 11. The mis-clamp detection cam switch 12 is provided in the transfer 10 and inputs an ON signal when the feed angle is between about 130 degrees and about 230 degrees as shown in FIG. 9, and the clamper 11 of the transfer ends the clamp and advances. It is OFF at the middle. The mis-unclamping detection cam switch 13 is connected to the clamper 11.
Finishes unclamping and returns O in the middle of return
N, and OFF in other ranges.

The work shift data 15 is a signal input when the material supply device 9 shown in FIGS. 11 and 12 supplies a work to the idle stage Ido in synchronization with the movement of the feed bar 10A. Work shift strobe 16
This is a signal input when the feed bar 10A conveys, that is, when the advance is completed. The final stage extraction 17 is a signal to be input when the work is extracted from the idle stage Ide.

As shown in FIG. 2, the option specifications are displayed on the display 6, and the number of press machines, the number of clampers, and the direction of conveyance are set and input by operating the keyboard 5 to configure the transfer press line. Subsequently, the data settings shown in FIGS. 3, 4, and 5 are sequentially displayed on the display 6, and the cursor is moved to the position of the large arrow outside the right column.
Id (idle stage) is set and input alone, a clamper to be used is set and input in FIG. 4, and each stage is set and input to the idle stage Id or the press working stages 1P to 6P in FIG. The above setting data is output from the I / O port 8 to each press machine as each press setting output 18 in FIG.

FIGS. 6 and 7 show examples of operation monitor screens on the display 6 corresponding to the product processing data set as described above. FIG. 6 shows a screen of an operation monitor of a product produced by interlocking the presses 1P and 2P and the presses 4P and 5P in the transfer press line shown in FIG. 11, the press 3P being produced as an idle stage Id, and the press 6P being produced alone. FIG. 7 shows an operation monitor screen of a product produced by interlocking three press working stages with the press 1P and one press work with the press 3P in the transfer press line shown in FIG.

FIG. 8 is a view showing the structure of the press machine P1 to the press machine P.
In the example of the screen on the display 6 of the product produced by providing each of the idle stages Id during the period up to 5, the work stage is set and input in the first stage Ido.
When setting and inputting work presence on another stage, the cursor can be moved and set.

As described above, when the required setting input is completed, the position data of each press working stage, the position data of the idle stage, and the use data of the clamp are stored in the ROM 3 and the RAM 4 and correspond to each stage in the memory. As shown in FIG. 10, a shift register for a processing step of a product to be produced is prepared, the input work presence / absence state is fetched, and a work shift strobe 16 for each transfer is performed.
Input the work shift data to the lower bits by
Shift bit by bit. At this time, the hatched bits that are not used are skipped as indicated by arrows and shifted.

If the data of the shift register and the signal of the work detector 11A input to the I / O port 8 do not match in the range of the input ON from the misclamp detection cam switch 12, an abnormal signal 21 is transmitted. While the transfer press line is stopped, the display 6
Displays the abnormal clamp location (mis-clamp or work setting failure). Similarly, when the detection range does not match even in the detection range of the cam switch 13 of the mis-unclamping detection cam, transmission of an abnormal signal and display of the abnormal clamping location are performed.

Further, based on the state of the shift register shown in FIG. 10, the work output 19 of each press machine is transmitted to each press machine at each transport, so that the press machine without the work cannot be started. Has a lock function. In the above description, the signals are compared, and if they do not match, an abnormal signal is transmitted by the CPU 2. All stage work no output 20
Is used to disable the transfer press line.

Such processed data is stored and stored in a memory as a data bank. Based on the processing data of the product, the feed monitor device operates, and press processing in the transfer press line is performed corresponding to various product processing steps from the loading of the material to the completion of the processing of the product.

[0020]

As is apparent from the above description, according to the present invention, even if the processing steps are changed depending on the product to be produced, the processing data (use condition data) corresponding to the product is used.
Can be easily changed, and a feed monitor device of a transfer press line that can be operated with high efficiency can be provided.
