[Action]

 The operation of the present invention (one-shot display and machine operation status) will be described below. For example, the molding time of the continuous automatic molding machine (seconds, the same applies below) is taken in (input) via the input IC. In the example of FIG. 3, the one-shot seconds (one-shot count) is input to the 4-digit counter IC via the input pulse generation IC (latch pulse generation IC), and The one-shot count input to the 4-digit counter IC and the numerical value input from the clock pulse generation IC are processed to select the 4-digit seconds.

The four-digit seconds of the selected one-shot counter issues a display command to any one of the LED display units via the digit driver display IC. On the other hand, for the display unit selected above, the first digit is numerically displayed on the display unit via the 7-segment decoder driver display IC.

As described above, when a certain one-shot digit is displayed on a certain display unit, the digit driver display IC then issues a display command to one of the display units outside the LED display unit. Is issued, and the digit of the number of one shots is numerically displayed on the next display section from the 7-segment duder display IC. As described above, by repeating the operation (operation) and the procedure, the one-shot seconds are displayed in each of the other digits, that is, the other two digits in the example of the present proposal, and as a result, the one-shot seconds are displayed. Is displayed in 4 digits (the number of digits is not limited).

As described above, the one-shot counter is displayed on the display, and at the same time, the pulse generating circuit for inputting pulse signals is input from the input pulse generating IC via the delay circuit. From the IC for reset (pulse generation IC for reset), a reset signal is input to the 4-digit counter by the IC, and the number of seconds processed is deleted. A numerical value corresponding to the next one-shot detection seconds is input from the pulse generation IC.

By repeating the above operation, the operation time of molding by the continuous automatic molding machine, that is, the one-shot counter is repeatedly displayed, and when the detected number of seconds is the reference number of seconds, it is always constant. Numerical value is displayed, and in other cases, that is, other than the reference second, the detected second is displayed. This is a device useful for confirming the occurrence of defects in molded products, operating conditions of the automatic molding machine, and process control.

Next, the molding time (seconds, hereinafter the same) of the continuous automatic molding machine shown in FIG. 5 is taken in (input) via the input IC, and the average value of the one-shot detection seconds is displayed. In the one-shot time counter, when the switch is turned on, a continuous operation command is given to the preset digit down counter IC for one digit. Therefore, the one-shot seconds (one-shot count) generated for each one-shot is input to the 4-digit counter IC via the input pulse generation IC (latch pulse generation IC) and The one-shot count input to the 4-digit counter IC and the numerical value input from the clock pulse generating IC are arithmetically processed to select the 4-digit seconds.

The selected four-digit seconds of the one-shot counter issues a display command to any one of the display units of the LED display via the digit driver display IC. On the other hand, for the display unit selected above, the first digit is numerically displayed on the display unit via the 7-segment decoder driver display IC.

As described above, when a certain one-shot digit is displayed on a certain display unit, the digit driver display IC then issues a display command to one of the display units outside the LED display unit. Is issued, and the digit of the number of one shots is numerically displayed on the next display section from the 7-segment duder display IC. As described above, by repeating the operation (operation) and the procedure, the one-shot seconds are displayed in each of the other digits, that is, the other two digits in the example of the present proposal, and as a result, the one-shot seconds are displayed. Is displayed in 4 digits (the number of digits is not limited).

As described above, the one-shot counter is displayed on the display, and at the same time, the pulse generating circuit for inputting the pulse signal from the input pulse generating IC for inputting the pulse signal through the delay circuit. From the IC for reset (pulse generation IC for reset), a reset signal is input to the 4-digit counter by the IC, and the number of seconds processed is deleted. A numerical value corresponding to the next one-shot detection seconds is input from the pulse generation IC.

Then, when the average value of the one-shot seconds is to be displayed, the switch is turned off. As a result, a command to generate the shot seconds every 5 shots is transmitted to the 1-digit preset down counter IC. On the other hand, via the micro-reed relay, the auxiliary clock pulse generation IC issues a command to the 4-digit counter IC to calculate the average value of the shot seconds every 5 shots, and based on this command, the 4-digit counter From the IC, the reference seconds are the same as above, and the average value of the one-shot detection seconds is displayed on the display. After this display, in the same manner as described above, a reset signal is input from the input pulse generation IC to the 4-digit counter via the delay circuit and the pulse generation IC for cut, and the average The value is deleted, and the numerical value corresponding to the next one-shot detection seconds is input from the clock pulse generating IC to the 4-digit counter IC.

By repeating the above-mentioned operation, the operation time of molding by the continuous automatic molding machine, that is, the one-shot counter is repeatedly displayed, and when the detected number of seconds is the reference number of seconds, it is always constant. Numerical value is displayed, and in other cases, that is, other than the reference second, the detected second is displayed. This is a device useful for confirming the occurrence of defects in molded products, operating conditions of the automatic molding machine, and process control.
