The present invention relates to a cigarette filter puncher, and more particularly to a PLC program automatic control method for controlling the cigarette filter puncher laser.

Conventionally, the cigarette filter perforator laser is controlled with an analog device. However, the configuration of the analog device is very complicated, which makes the operation process inconvenient, processing time consuming, and the cigarette filter perforator laser is manually operated. The problem that needs to be controlled was caused.

In order to solve this problem, the present invention constructs a simple PLC program sequence that automatically controls the cigarette filter perforator laser, thereby simplifying the work process by the PLC program sequence and saving the processing time by the simple work process. In addition, the cigarette filter perforator laser is automatically controlled by the configuration of a simple PLC program sequence, the present invention will be described in detail based on the accompanying drawings.

As in the configuration of the PLC program sequence of FIG. 1, the emergency stop switch contact in which the leisure abnormal state input switch contact point Po2, the pulse abnormal state input signal contact point Po9, and the puncturer abnormal state input signal contact point PoA are connected in parallel. Connect (Po1) to relay (Mo) in series, automatic operation select switch contact (Po0) master control cell lock address (MCS0), relay contact (Mo1), pulse generator speed zero signal contact (PoE) and output gate (PIB) ) Is connected in series, and the input contact (PIB ¹ ) and the output gate (P17) are connected in series.

In addition, the drilling start remote switch contact point PO3 connected in parallel with the input contact point PIC ¹ , the input contact point PIB ² relay contact point M ¹ ₉ and the output gate PIC are connected in series, and the relay point M4 is connected. Are connected in parallel, the input contacts (PIB ³ ), (PIC ² ) and the output gate (P19) are connected in series, the input contacts (P ¹ ₁₉ ) and the timer (T7) are connected in series, and the timer input contact (T) is connected. ₇ ¹ ) Connect the relay (M5) in series and connect the input contact point (PIC ³ ) to the input signal contact point (PO8) to be processed and the pulse generator speed control to connect the signal contact point (POE) and the timer (T10) in series.

In addition, the timer input contact T ¹ ₁₀ and the input contact FO94 are connected in series with the relay M8, and the puncture stop remote switch contact PO4 and the relay M9 in which the relay contact MO2 is connected in parallel are serially connected. Connect a relay contact (M ² ₁₀ ) and a relay (M ² ₉ ) in series, but connect the master control self-lock clear terminal (MCSO CLR) in parallel to the relay contact (M ² ₉ ) and relay (M ² ₁₉ ). To configure the PLC program sequence.

The effects of the present invention configured as described above will be described in detail based on the PLC program sequence of FIG. 1.

In the PLC program sequence, the laser abnormal state input switch contact point (Po2) and the pulse generator abnormal state input signal contact point (Po9), the puncturer abnormal state input signal contact point (PoA) and the emergency stop switch switch contact point (Po1) have been checked for abnormality. If there is an abnormal state, the relay (Mo) turns on.

When the automatic operation select switch contact Po0 is turned on while the relay Mo is turned on, the abnormal state and the pulse generator speed PoE become zero, and the automatic operation range is turned on.

In this case, when the output gate PIB is turned on, the input contact PIB ¹ and the output gate P17 are turned on, and the beam output of the laser is automatically set.

The sequence operates sequentially in the above order.

Here, MCS0 is a mask control self-lock address for easily configuring the program structure, and constitutes an interlock block with priority.

Therefore, when the drilling start remote switch contact point PO3 is on, the input contact point PIB ² , the relay contact point M ¹ ₉ , the output gate PIC, and the relay M4 turn on, the count is reset, and the punching point is performed. The start lamp is on.

Therefore, input contact point (PIB ³ ), (PIC ² ) and output gate (P19) are turned on to operate the pulse generator and drilling machine (Piercing machine) to turn on the input contact point (P ¹ ₁₉ ) and at the same time the timer (T7) for 1 second. While the timer contact T ¹ ₇ is turned on and thus the relay M5 is turned on to open the light-blocker.

Thereafter, the timer T7 is turned off. In this state, when the input signal contact Po8 to be processed is turned on while the light breaker is open, the pulse generator speed zero signal contact PoE ¹ is turned on to operate the timer T10 for 10 seconds.

When the timer T10 is operated, the timer contact T ¹ ₁₀ and the input contact Fo94 are turned on, and thus the relay M8 operates to raise the scheduled buzzer for 10 seconds. At this time, the puncturing stop mortar switch contact (Po4) and the relay (M9) is off and the perforator is stopped, and thus the relay contact (M ² ₉ ) and the relay (M ² ₁₀ ) is turned off to close the light circuit breaker.

Where MCSO CLR is a mask control self-lock clear that clears the command of master control self-lock clear to " 0 ".

In this way, the present invention is to configure a simple PLC program sequence that automatically controls the cigarette filter perforator laser, to simplify the work process by the PLC program sequence, and to save the processing time by the simple work process. It also has the advantage of automatically controlling the cigarette filter punch laser.
