The present invention relates to a packaging printing film processing apparatus that performs a bonding and cutting operation on a predetermined line while feeding a printed film in a rolled manner. In particular, when the printing film is supplied in a plurality of lines, the predetermined position of each printing film is precisely set. The present invention relates to an in-situ control device for packaging printing film in which the control setting is performed so that the sealing cutting operation of the film is performed accurately.

In general, in packaging containers of various commodities, a package printing film processing is known, in which a printed film is wound in a series of rolls and sealed first, and a cutting process is performed. At the same time as supplying, the printing film is intermittently stopped, and sealing and cutting of one side thereof is performed to provide the customer with the first processing completed.

For example, the packaging printing film processor may include a printing film supply roll 41, various printing rods 45, a film height adjusting device 42, a sealing heater, and a cutter 43 as shown in FIGS. 1 and 2 and 3. The back is arranged in the main body 44, and between the height adjusting device 42, the heater and the cutter 43, the driving roll 47a for the intermittent transfer of the film and the driven roll as shown in FIGS. 47b is disposed, and the drive roll 47b is a belt drive means, a gear drive shaft 51, a length adjusting port 47f and a gear of the motor 48 and the respective parts as shown in FIGS. 1 and 4. It is designed to intermittently rotate the film flowing through the die one by one by intermittently rotating through the rod 47d and the fan bone gear 47c and the pinion 47e, and to perform the stop control operation.

However, in this prior art, the film advancing by one section by the driving roll 47a and driven roll 47b does not stop at a predetermined position which is a printing boundary line, and mechanically related to the forward rotation driving operation of the fan gear 47c. It was caused by an inertia and the like, which was slightly relaxed and drooped or preceded, causing an error that the sealing cutting operation could not be made at the interface between the film and the film.

That is, when the boundary surface of the film having a series of continuous printing surfaces is stopped at the position displaced from the cutter 43, the sealing and cutting operations are not performed at the desired site, and the sealing and the printing surfaces are continuously cut. It was to be.

Therefore, in order to prevent such a phenomenon, an operation for positioning a predetermined position of the film is frequently required, and thus, it was not inconvenient.

On the other hand, the transfer stop control of the film as described above is not difficult to work when the film flows in a single line, but when the film flows in a plurality of lines as described above the film positioning control operation is impossible as above Until now, there were only devices that could only be treated as a single line.

This resulted in the disadvantage that the printed packaging film processor as described above can be designed with only one line, resulting in lower overall productivity.

An object of the present invention is to improve the above-mentioned conventional problems.

The present invention has a technical means capable of simultaneous control of multiple lines in such a film processor, and improves the processing efficiency of the packaging film processor, and at the same time provides a control device for positioning the printing film of the packaging film that can perform a reliable processing operation. Provided.

In particular, the present invention provides a film printing surface sensing device capable of vertical and horizontal position movement while having a light sensing sensor between a height adjusting device for intermittently transporting a film and a driving roll, and detected by the film printing surface sensing device. A plurality of solenoid devices for preventing the transfer of the film in position and the multiple stop control circuit for synchronous control with respect to the drive source of the drive roller.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Intermittently conveying the film and the height adjusting device 42 to adjust the height of the film in order to select and adjust the sealing position of each printing film as shown in Figures 1, 2, 3 and 5, The film printing surface detection apparatus 1 was installed between the driving roll 47a and the driven roll 47b which can be stopped.

The film printing surface apparatus 1 is screwed to a vertical shaft 13 rotatably installed at a predetermined portion of the main body 44 as shown in FIGS. 1, 2, 6, and 7 to move the upper and lower positions. The connector 12 and the horizontal shaft 11 fixed to the connector 12 were formed, and the notch groove 11a was formed in the horizontal axis 11 in the longitudinal direction to form four light sensing sensors 1a-1d. ) Is arranged to be horizontally movable by rail type.

In addition, the sensing signal input from the film printing surface sensing device 1 is a gear rod 47d eccentrically connected to the drive shaft 51 and the rotation through the motor 48 and each belt pulley as shown in FIGS. 1 to 5. ), The fan-shaped gear 47c connected to the gear rod 47 so as to rotate easily, and the pinion 47e engaged therewith, and the intermittent operation in the drive mechanism 5 for driving the driven and driven rolls 47a and 47b. The solenoid device 3 on the line side in FIG. 8 is applied to the multiple stop control circuit 2 intermittently driving in synchronization with the control signal.

On the other hand, the sealing heater 49 for heating to seal the print film is installed before the height adjusting device 42 as shown in Fig. 3, and the illustration is omitted in Figs.

Incidentally, the multiple stop control circuit 2 shows the embodiment as shown in FIG.

Here, the photo sensor PS1 for detecting the printed surface of the film, the optical sensor unit 21 including the signal amplification transistors Q2, Q3, the fut, etc., and the output of the optical sensor unit 21 Photocoupler for arbitrarily selecting the circuit operation of the pulse transformer part 22 which drives the solenoid SL control thyristor SR1, and the optical sensor part 21 and the pulse transformer part 22 with a manual operation switch SW. PT1 and the mechanical synchronous signal are rotated by the drive shaft 51 of the drive mechanism 5 as shown in FIGS. 1 and 3 to block the optical signal from the light emitting portion to be detected or blocked by the photosensor PS2. 52, a synchronous detection unit 23 by the photosensor PS2 and the switching transistor Q5 circuit detected by the optical sensor means, and a fut PUT2 operated by a timer by the signal detected by the synchronous detection unit 23; ), Thyristor (SR2), resistor (R), capacitor (C1), transistor (Q6), NAND gate (G1) Synchronous timer switching unit including NAND gate (G2), transistors (Q7, Q8), thyristor (SR3) for switching the driving of the synchronization timer according to the immer unit 24 and the logic output of the synchronization timer unit 24 ( 25, a turn-off unit 26 for switching the NAND gate G8, the transistors Q9, Q10, and the thyristor SR4 to the output of the thyristor SR1, and the synchronous timer switch unit 25. The power supply control unit 27 includes a gate G4, a transistor Q11, and a photocoupler PT2 transistor Q12 that apply a power output only to a synchronous condition to the thyristor SR3.

The present invention of such a configuration is as follows.

The packaging printing film printed with a predetermined product name and various drawings is heat-sealed in the sealing heater 49 through the printing film supply roll 41 and various guide rods 45 of FIGS. After the device 42, the film printing surface sensing device 1, and the solenoid device 3, the driving and driven rolls 47a and 47b are connected, and the film passed through the driving and driven rolls 47a and 47b is cutter 43 In this state, when the intermittent power is transmitted from the driving mechanism 5 of FIG. 5, the film is advanced by a known means by the driving and driven rolls 47a and 47b.

At this time, as the film is transferred, a predetermined printing surface is detected by the film printing surface detecting apparatus 1, and the detection signal is a detection signal by the photosensor PS1 on the side of the optical sensor 21 of FIG. 9.

As a result, the detection input signal of the predetermined part detected by the photosensor PS1 is amplified by the transistors Q2 and Q3 and the fut PUT1 by a predetermined size to drive the transformer T of the pulse transformer unit 22 to drive the thyristor ( SR1 can be turned on, and at this time, the optical sensor part 21 and the pulse transformer part 22 can be multiple.

When the thyristor SR1 is turned on via the solenoid SL and a high signal is applied to the anode side of the thyristor SR4, when the thyristor SR4 is turned on, the solenoid SL is driven so that the film does not flow further from the predetermined position. It is controlled by position.

On the other hand, the solenoid SL has a drive shaft 51 as shown in FIGS. 1 and 4 when the driving and driven rolls 47a and 47b for the intermittent transfer of the film are intermittently transferred by the driving mechanism 5. ) Is rotated and the blocking plate 52 fastened as a bolt 53 blocks the light sensor and the photo sensor PS2 as the light receiver as indicated by the dashed-dotted line, thereby causing the photosensor PS2 to be turned off accordingly. Transistor Q5 is turned on and applied to one side input terminal of NAND gate G2 through the manual operation switch SW, so that a low signal appears at its output stage and this signal is applied to one input terminal of NAND gate G3. A high signal is output to the output terminal to sequentially turn on the transistors Q10, Q8, and thyristor SR4 to drive the solenoid SL.

At this time, the NAND gate G4 is operated like the NAND gate G3 to turn on the transistor Q11, thereby turning on the photocoupler PT2 and amplifying the transistor Q12 to charge the capacitor C2.

At this time, the anode side of the thyristor SR3 is charged with + charge, and the anode side of the thyristor SR4 is charged with −charge.

When light is transmitted from the light emitter to the photosensor PS2 in the synchronization detector 23, the photosensor PS2 is turned on and the transistor Q5 is turned off accordingly, so that the input terminal of the NAND gate G2 is connected to one side of the NAND gate G2 through the switch SW. Since the low signal is input, the high signal is output to the output terminal of the NAND gate G2.

In this way, the high signal is applied to one input terminal of the NAND gates G3 and G4. Thus, a low signal is output to the output terminal of the NAND gates G3 and G4 where the high signal is input to the other input terminal, thereby turning off the transistors Q10 and Q11. At the same time, transistors Q7 and Q8 are turned on and the thyristor SR3 is turned on, and the previously charged capacitor C2 is discharged to turn off the series SR4 by a reverse voltage to return to its original state. .

Here, the synchronous timer unit 24 is a timer to prevent the operation of the machine in the state that the solenoid (SL) is turned on and left for a long time there is a risk of damage to the solenoid (SL) and components, as a circuit for preventing this, its operation When the photo sensor PS2 of the synchronous detection unit 23 does not receive light and is turned off, the transistor Q5 is turned on, passes through the switch SW, and charging of the capacitor C1 is started through the high resistance R. Turn on Put (PUT2).

Accordingly, the two-input signal of the NAND gate G2 is triggered by the thyristor SR2 to be converted into a low and a high signal, and a high signal is output to the output terminal thereof. Therefore, the thyristor SR3 is turned on and turned on through the transistors Q7 and Q8. SR4) is turned off to block the driving of the solenoid SL.

Here, the NAND gate G1 is for discharging the electric charge charged in the capacitor C1 when the machine is operating like the transistor Q6.

The NAND gates G1 and G2 and the NAND gates G3 and G4 are inverted to operate according to the operating states of the photosensor PS2 transistor Q5 and the switch SW.

In addition, the optical sensor, which is the photosensor PS1, can move horizontally according to the number of lines in the horizontal axis 11 to hold the horizontal position as shown in FIG. 6, and further, in the horizontal axis 11 according to the sensing position of the optical sensor. Upper and lower values by rotating the handle on top of the vertical axis 13 to rotate the vertical axis 13 is capable of adjusting the position of the horizontal axis 11 with the connector 12 screwed thereto.

Therefore, it is possible to selectively arrange and fix the number of lines of the film flowing in the die of the main body 44, the sensor sensing height, and the like.

When the photocoupler PT1 is turned off to stop the operation of the device by the manual operation switch SW of FIG. 9, the circuit operation such as the optical sensor unit 21 and the thyristor SR1 driving the solenoid SL is performed. Stop it.

As described above, the present invention provides an in-situ control device capable of controlling the printed packaging film that is intermittently transferred to multiple lines in the sealing and cutting processing apparatus of the printed packaging film to be in place and stopped, thereby operating the device. In addition to improving reliability, the packaging film can be processed in a plurality of lines, which is an advantageous feature to improve the device efficiency.
