The present invention relates to a film processing apparatus for winding a wrapping film or the like on a sheet in a rolled manner and supplying the film to a predetermined line. In particular, the control mechanism provided to control the film transferred to the film processing apparatus is achieved with a simple configuration. The present invention relates to a film feed control device in which properties can be maintained well.

In a film processing apparatus which cuts or seals to a predetermined size while conveying a sheet-like plain film or printed film to a predetermined line, a film feed control mechanism for feeding and stopping the film by its size in a transfer line Is provided.

FIG. 1 shows the overall configuration of the film processing apparatus presented in the Utility Model Registration Application No. 89-18787 (Applied Control of Packaging Printing Film) filed by the applicant. In FIG. Conceptually illustrated.

Here, between the film feed roll 41 and the plurality of film guide rods 45, the film height adjusting device 42, the sealing heater 49 and the cutter 43 intermittent transfer to transfer or stop the film by a predetermined distance The control mechanism 47 is provided.

Then, the hepatic blood transfer control mechanism 47 engages with the crank rod 47d and the fan gear 47c connected to the crank rod 47d and the fan gear 47c connected to the crank rod 47d as shown in FIG. And an intermittent feed drive roll 47a for moving the film along with the driven roll 47b and stopping the predetermined section. The flat gear 47c holds the film in a fixed position when the film is transported and stopped for one section. A latch or a stop brake, not shown, is provided.

However, such a conventional intermittent feed control mechanism 47 does not stop at the position where the film is advanced one by one by the intermittent feed drive roll 47a and the driven roll 47b, and the like, such as a fan gear 47c. There is a disadvantage that the error is sustained in an environment in which sealing and cutting operations are to be accomplished at the interface of the film by being relaxed or drooping slightly by mechanical inertia related to the driving operation. And this phenomenon would be inconvenient because man-made manipulations were required to place the film from time to time.

On the other hand, the drive mechanism such as the crank rod 47d has been subjected to mechanical vibration, abrasion damage, noise, etc. and caused maintenance problems and noise pollution due to the use of such a device. It was hard to avoid the rise.

An object of the present invention was devised to improve the problems of the prior art as described above, and the intermittent contact drive of a solenoid control associated with a solenoid control circuit with a mechanism and a rotating roll connected to a power source and idle at normal conditions It is to provide a film feed control device that allows the feed control of the film in a manner.

The present invention is a non-powered driven roll driven by the first solenoid and the non-powered driven roll is rotated in particular in the film transfer line with the rotary roll installed with the power mechanism and the solenoid control circuit to be in contact with or separate from the rotary roll And a film transfer control mechanism having an associated configuration with a second solenoid which temporarily holds the transfer film when separated from the roll.

Another feature of the present invention is that the solenoid control circuit has an encoder installed on a rotary roll when the film is plain, and the counter logic outputs to the sensor unit installed in relation to the counter logic and the cutter, etc. A reset sensor unit for resetting the signal; The optical sensor unit includes an optical sensor unit that provides the output to the signal amplifier unit.

This will be described in more detail below.

4 shows the film feed control mechanism 10 according to the present invention, which is installed at the same position as the film feed line between the height adjusting device 42 and the cutter 43, that is, the conventional intermittent feed control mechanism 47. .

In the lower part of the film feed line, an idling rotary roll 17 extending from the power mechanism 18 to the belt 19 is provided, and an encoder 16 is attached to the shaft of the idling rotary roll 17.

In addition, a non-powered driven roll 11, which is rotated or separated in contact with the rotary roll 17, is disposed together with the cutter mechanism 15, and the non-powered driven roll 11 is disposed above the rotary roll 17. It is provided so that the lifting and lowering action can be continued from the lever 13a of the axial point member 13 on one side, and this non-powered driven roll 11 together with the spring 12c is a solenoid rod 12b and a solenoid body 12a. It is connected to the first solenoid 12 including. In addition, the ground rod 14b of the second solenoid 14 including the solenoid body 14a is raised and lowered at the front end of the film transfer line in which the rotary roll 17 and the driven roll 17 are installed up and down, and thus the ground member 14C. ) Can be interviewed or separated.

On the other hand, the solenoid control circuit 2 which controls the rotation amount and rotation section of the rotation roll 17 by the 1st solenoid 12 with respect to FIG. 5 and FIG. 4 is shown.

Here, the counter logic 22 to which the encoder 16 and the reset sensor unit 21 are connected, and the signal amplifying unit 23 connected to the output of the counter logic 22 and the output of the signal amplifying unit 23 are connected. The optical sensor part 24 is connected to the 1st, 2nd solenoids 12 and 14 and another input terminal of the signal amplifier 23. As shown in FIG.

Here, the first and second solenoids (12, 14) are connected to the circuit to operate on or off at the same time by the output signal of the signal amplifier 23, their mechanical configuration is mutually force field, that is, on In this case, the first solenoid 12 is configured to pull the solenoid rod 12B and the second solenoid 14 is configured to push the ground rod 14b.

The present invention of such a configuration is as follows.

That is, the present invention is a film supplied through the film supply roll 41 and the plurality of film guide rods 45, the sealing heater 49, the film height adjusting device 42, etc. as shown in FIG. As in the second solenoid 14 is passed between the grounding rod 14b and the grounding member 14c, between the rotary roll 17 and the non-powered driven roll 11, through the cutter mechanism 15 in order.

At this time, the transfer operation of the film, first, the cutting operation of the cutter mechanism 15 is completed, the reset sensor unit 21 detects the completion of the cutting operation in the solenoid control circuit 2 of FIG. 22), the counter logic 22 then counts the preset number by the film interval considering the diameter of the rotary roll 17 to the input of the encoder 16 installed on the rotary roll 17, At this time, since the counter logic 22 does not generate an output until the count number is reached, the first solenoid 12 maintains the off state.

In the off state of the first solenoid 12, the non-powered driven roll 11 is in contact with the rotary roll 17 by the elastic force of the spring 12c provided on the operating rod 12b, and the non-power driven roll 11 The film interposed between the driven rolls 11 is moved forward by a predetermined length to the right in the drawing by the driving force of the power mechanism 18.
