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

1 is a front view showing a film supply device of a four-sided film packaging machine according to an embodiment of the present invention, Figure 2 is a plan view showing a film supply device of a four-sided film packaging machine according to an embodiment of the present invention, and FIG. It is a side view showing a film supply device of a four-sided film packaging machine according to an embodiment of the present invention, and FIGS. 4 and 5 are a perspective view and a front view showing a roll arrangement relationship in the film supply device of a four-sided film packaging machine according to an embodiment of the present invention. .

As shown in FIGS. 1 to 5, the four-sided plastic wrapping machine includes a product supply unit 10 for supplying products such as masks to a conveyor means, a vinyl supply unit 11 for supplying vinyl for product packaging, and a vinyl It includes a product packaging unit 12 for packaging products while performing processes such as printing, width and length sealing, punching, and slitting.

Here, the structure and operation of the product supply unit 10 and the product packaging unit 12 are the same as those of the product supply unit and product packaging unit provided in known plastic packaging machines, so detailed descriptions thereof will be omitted.

In this four-sided vinyl wrapping machine, the vinyl supply unit 11 functions to continuously supply vinyl while advancing it in a predetermined trajectory using a combination of a plurality of roll parts. Divided by 2, and each vinyl in this divided state is provided to the product packaging part 12 side.

To this end, the vinyl supply unit 11 includes a roll part 13 for supplying vinyl as a means for unwinding and supplying vinyl wound in a roll form.

The vinyl supply roll part 13 includes a roll vinyl mounting roll 13a installed in a horizontal position while being supported through one end at the upper end of the side wall of the packaging machine frame 20, and a roll vinyl mounting roll at this time ( 13a) includes a ring-shaped roll vinyl holder 13b holding both ends of the roll vinyl while being assembled.

Here, the pair of roll vinyl holders 13b can be moved and fixed on the roll 13a for mounting the roll vinyl, so that the distance between them can be adjusted according to the roll vinyl of various specifications.

In addition, the roll 13a for mounting the roll vinyl has a freely rotatable structure, and when the vinyl is released from the roll vinyl by the driving of the roll part 15 for vinyl transfer, the roll vinyl is rolled by the unwinding force at this time. It can be rotated naturally together with the vinyl mounting roll 13a.

In addition, the vinyl supply unit 11 includes a roll part 14 for vinyl balance as a means for imparting appropriate tension to the vinyl.

The roll part 14 for vinyl balance is disposed in front of the roll part 13 for vinyl supply, and one end of the roll axis 14d of the position-fixed roll 14a is placed at the upper end of the side wall of the packaging machine frame 20. It is installed in a horizontal position while being supported through

At this time, one end of the roll shaft 14d of the position-fixed roll 14a is assembled through the side wall of the packaging machine frame 20 through a bearing (not shown) so that it can be rotated around its own axis.

The vinyl balance roll part 14 includes an upper position fixed roll 14a and a lower position floating roll 14b, and a position fixed roll 14a and a position floating roll 14b, which are horizontally arranged from top to bottom. It includes a pair of roll bars 14c connecting both ends of the liver, respectively.

Here, the position-fixed roll 14a and the position-flow type roll 14b are assembled in a freely rotatable structure on each roll axis 14d and can be naturally rotated by friction with the vinyl transported on the roll.

In addition, between the roll bars 14c on both sides, a trouser pin 14e positioned side by side between the upper and lower position fixed roll 14a and the position floating roll 14b is installed, and at this time, the trouser pin 14e ) serves to integrally bind the roll bars 14c on both sides that bind the upper and lower roll shafts 14d.

In particular, the lower position floating roll (14b) has the position fixed roll (14a) as the central axis according to the tension acting on the vinyl, in other words, the roll axis (14d) of the position fixed roll (14a) as the central axis It makes a pendulum movement back and forth.

In addition, while the position floating type roll 14b performs a pendulum movement, the roll axis 14d of the upper positioning type roll 14a also rotates around its own axis at the same time.

Therefore, the vinyl supplied from the side of the roll part 13 for vinyl supply crosses the upper position-fixed roll 14a clockwise, continues to extend downward, and passes through the lower position floating roll 14b counterclockwise. After spanning in this direction, it proceeds along a path extending toward the vinyl guide roll 17 located above this.

In this state of progress, when tension in the forward direction of the forward direction acts on the vinyl, that is, when the vinyl is pulled forward, the positional floating roll 14b is also pulled forward while pendulum movement by the force at this time, (For example, a combination of a position-fixed roll, a position-float roll, and a roll bar assumes an inclined posture), and when the tension applied to the vinyl is released, the position-float type roll 14b at this time is restored to its original state by its own restoring force. (For example, a combination of a position fixed roll, a position floating roll, and a roll bar assumes a vertical posture).

Depending on the tension acting on the vinyl, the position floating hole 14b can balance the progress speed of the vinyl while repeating the pendulum movement.

In addition, the vinyl supply unit 11 includes a roll part 15 for transferring vinyl as a means for transferring vinyl passing between two rolls by frictional force.

The vinyl transfer roll part 15 includes two rolls, that is, a driving roll 15a and a driven roll 15b disposed in a state in which outer circumferential surfaces face each other with the vinyl interposed therebetween.

The drive roll 15a and the driven roll 15b are disposed below the roll part 14 for vinyl balance, supported at both ends in a horizontal position between the side wall of the packaging machine frame 20 and the roll plate 15c, and rotated together. installed in a possible structure.

At this time, the drive roll 15a rotates by receiving power from a drive motor (not shown) through a sprocket (not shown) at one end and a chain (not shown) caught thereon, and the driven roll 15b In order to secure frictional force with the vinyl side, it is made in the form of a rubber roll wrapped with rubber on the outer circumferential surface.

In particular, an operating lever 15e is mounted on one end of the driven roll 15b, that is, an end supported by the roll plate 15c, and when the operating lever 15e is operated, the driven roll 15b It becomes possible to widen or narrow the gap between the drive roll 15a.

Here, the control lever 15e serves to maintain the fixed state of the driven roll 15b or release the fixed state of the driven roll 15b.

In addition, the roll shaft 15f serving as a support shaft of the driven roll 15d has an eccentric shaft structure having a stepped portion 15g, and the driven roll 15b mediates a bearing on the eccentric shaft portion. can be inserted and supported.

For example, the control lever 15e is coupled to the roll axis of the driven roll 15b, and when the control lever 15e is locked by turning it clockwise, the body portion of the control lever 15e at this time is locked. As the front surface of the roll plate 15c is pressed, the driven roll 15b can be fixed (the driving roll and the driven roll come into contact), and on the contrary, when the control lever 15e is tilted counterclockwise to release it, at this time The driven roll 15b becomes movable (when flipped counterclockwise, the driven roll becomes movable).

That is, when the control lever 15e is tilted to one side and released, the driven roll 15b can be moved. At this time, the distance between the driven roll 15a and the driven roll 15a can be adjusted while rotating the driven roll 15b. After adjusting the distance of (15b), when the control lever (15e) is flipped to the opposite side and locked, it is possible to maintain the adjusted distance at this time.

At this time, the entire roll shaft 15f including the driven roll 15b is resiliently supported by a lever on the roll shaft 15f and a spring supported at both ends between the upper end of the lever and the frame 20 of the packaging machine. supported, and accordingly, in a state in which the operating lever 15e is released, the driven roll 15b and the roll shaft 15f are subjected to a force to rotate counterclockwise.

Therefore, when the control lever 15e is tilted to one side and released, the driven roller 15b rotates as much as the eccentric amount of the roll shaft 15f, which is an eccentric shaft, and the gap with the drive roll 15a widens, and the operation When the lever 15e is operated in the opposite direction, the gap between the drive roll 15a and the driven roll 15b is narrowed and combined in a friction structure, so that the vinyl passes through the gap (engaged between the drive roll and the driven roll), so that the vinyl Supply transfer will take place.

By allowing the distance between the drive roll 15a and the driven roll 15b to be adjusted in this way, even when the specifications (eg, thickness, etc.) of the vinyl (film) change, there is an advantage of being able to actively cope with this.

In addition, four pins 15d disposed in a lattice shape and parallel to each other in a horizontal position are installed between the side wall of the packaging machine frame 20 and the roll plate 15c to form a drive roll 15a and a driven roll 15b. ), and among the four pins 15d installed in this way, three pins 15d, two upper left and right pins 15d and one lower right pin 15d have a vinyl guide roll ( 17) is installed in a freely rotatable structure.

Therefore, the vinyl extending downward after exiting the roll part 14 for vinyl balancing and passing through the upper vinyl guide roll 17 is the vinyl guide roll 17 in the upper left position → the drive roll 15a and Between the driven rolls 15b → the vinyl guide roll 17 at the upper right position → the vinyl guide roll 17 at the lower right position in turn, and then along the path extending toward the roll part 16 for vinyl cutting at the bottom Progress, and the vinyl progressing along this traveling trajectory can be given a conveying force by the frictional contact between the drive roll 15a and the driven roll 15b.

In addition, the vinyl supply unit 11 includes a vinyl cutting roll part 16 as a means for dividing the vinyl into 1/2 by cutting the middle of the width of the vinyl.

The vinyl cutting roll part 16 has a cutter groove 16a along the outer circumferential surface and is supported at both ends in a horizontal position between the side wall of the packaging machine frame 20 and the roll plate 16h, and installed in a rotatable structure A die roll 16b, disposed parallel to the top of the die roll 16b, supported at both ends in a horizontal position between the side wall of the packaging machine frame 20 and the roll plate 16h, and installed in a rotatable structure A cutter shaft 16c, a “c”-shaped cutter holder 16d coupled to a position midway along the length of the cutter shaft 16c and rotatable up and down with the shaft, a cutter holder 16d rotatable on the cutter holder 16d and a ring cutter 16e installed into the structure.

Here, the ring cutter 16e is a disc-shaped cutter having a cutter blade on its outer circumferential surface, and serves to cut the vinyl passing therebetween while contacting the cutter groove 16a in the die roll 16b through the cutter blade. will do

In addition, the vinyl cutting roll part 16 is a means for providing force so that the blade portion of the ring cutter 16e is always pressed to the die roll 16b side, and includes a tension bar 16f and a tension spring 16g. includes

The tension bar 16f is coupled to one end of the cutter shaft 16b through a lower end so that it can be rotated up and down together when the cutter shaft 16b rotates.

The tension spring 16g is installed in a structure in which both ends are fixed between one side of the packaging machine frame 20 and the upper end of the tension bar 16f, and always pulls the tension bar 16f downward to rotate the cutter shaft 16d counterclockwise. As a result, the ring cutter 16e is always in contact with the die roll 16b by receiving a predetermined pressing force.

Accordingly, when the vinyl passes between the ring cutter 16e and the die roll 16b, the vinyl at this time is cut by the cutter blade of the ring cutter 16e, and eventually the width of the vinyl is halved into two parts. will be divided into

In addition, the vinyl supply unit 11 includes a plurality of vinyl guide rolls 17 as means for guiding the vinyl in a predetermined trajectory.

The vinyl guide roll 17 is a roll made in the form of a long circular bar, and is installed in a rotatable structure while maintaining a horizontal posture while being supported on the side wall of the packaging machine frame 20 through one end.

The vinyl guiding roll 17 serves to guide the vinyl passing through each roll part along a predetermined trajectory and finally guide it toward the vinyl direction changing roll 18.

In addition, the vinyl supply unit 11 includes a pair of upper and lower vinyl direction conversion rolls 18 as a means for changing the traveling direction of the vinyl divided in half by 90°.

The roll 18 for changing the vinyl direction is installed in a structure supported by the packaging machine frame 20 side while maintaining a horizontal posture inclined at 45 ° with respect to the vinyl traveling direction and disposed on the entry side of the product packaging unit 12. .

Accordingly, when the two sheets of vinyl cut in half from the vinyl cutting roll part 16 are transported along the vinyl guide roll 17 and then pass through the upper and lower vinyl direction conversion rolls 18, at this time The vinyl of the moving direction is bent by 90 ° and transferred in parallel with the product transport direction so that it can be supplied to the product packaging unit 12.
