An inclined portion ( G).

Here, the supply unit 21 is where the film fabric F wound on the input roller 11 is unwound and supplied. In addition, although the supplied punching object is limited to the film fabric (F), it is not necessarily limited to the film fabric (F) (base film). It is revealed in advance that the present invention can be applied to a variety of known sheet-type fabrics capable of performing a punching operation.

There are advantages to being able to.

And in FIGS. 10 and 11 , a two-row supply unit T2 and a discharge unit 23 can be seen. This employs a guide/pressing device of a pressing pressure control type while configuring the rollers in two rows to perform the simultaneous operation of the two strands of the film fabric (F).

This solves problems such as collision and overlap of two or more film fabrics (F), and blocks product defects and quality defects at the source to prevent separation or stable copper plates even when tension changes in films and tapes exist. do. Of course, it has versatility applicable to all kinds of films and tapes because it is possible to adjust and control the pressing pressure and roll width.

And as shown in FIG. 3, the punching part 22 corresponds to a part that continuously and automatically processes a desired shape through a punching operation on the film fabric F supplied from the supply part 21. 221a), but includes a base housing 221 disposed in the central lower portion. And the upper plate 222 having a blade on the work table 221a is regularly raised and lowered to perform punching by pressing.

and a lower mold 223 disposed to face the upper plate 222 , wherein the lower mold 223 includes a jig plate 224 .

Of course, it includes a lift driving unit including a lift motor for regularly raising and lowering the upper plate 222 .

And, as shown in FIG. 6 , the lifting shafts 225 are fixedly assembled to penetrate each of the corners of the upper plate 222 , and are assembled so that punching operations can be performed while ascending and descending by the lifting shafts 225 .

That is, the upper plate 222 regularly presses the film fabric (F) passing through the upper surface of the jig plate 224 in a state in which the blade is loaded, and engraves or cuts the shape to be processed on the film fabric (F). will perform

And at this time, since the elevating driving unit is located inside the base housing 221, the specific configuration thereof is not shown in the drawings, but the crankshaft and the camshaft are driven through the elevating motor to perform one rotation of crank work. Since it is a universal and well-known technology, a detailed description thereof will be omitted.

And it can be seen that the punching hole (F1) is formed on one side of the film fabric (F) by the punching part (22).

The discharge part 23 is integrally coupled with the punching part 22 from the opposite side of the supply part 21 as shown in FIG. 7 to draw and discharge the film fabric F punched from the punching part 22 perform the role of

To this end, the discharge unit 23 includes a servo motor 233 that provides a driving force necessary for transporting the film fabric F, a discharge roller 231 that rotates in conjunction with the servo motor 233, and the discharge roller ( 231) includes an auxiliary discharge roller 234 for pulling the film fabric (F) from behind.

That is, when the film fabric F is transported in the transport direction by the guide frame 232 having the discharge roller 231 and the inclined portion G, the auxiliary discharge roller 234 at the back receives it and receives the film The fabric (F) is pulled.

Here, the servomotor 233 includes a feedback circuit for having an automatic control system configured to set the position/direction/posture/rotational speed of an object as a control amount and follow a change in a target value.

Of course, the specific configuration of whether the servomotor 233 is electric or hydraulic is not limited.

Accordingly, the servomotor 233 can accurately perform speed control according to the transport distance data value, pitch amount, etc. of the original film F that is calculated and provided by the punching control unit 24 .

Next, the above-described punching control unit 24 is provided integrally on one side of the base housing 221 as a configuration for setting the overall working state of the punching machine 2 and performing automatic control by a preset program. .

As such, the control unit is equipped with a controller in which various control programs are built in, and is configured so that the working state can be appropriately set by the operator.

Next, we will look at the laminating machine (3) used in the lamination step of laminating the punched film fabric (F).

In the case of the laminating machine (3), it corresponds to a configuration for laminating the divided first film original fabric (F) and the second film original fabric (F).

In the case of the laminating machine 3, as is well known, it is a device configured to be laminated through a double-sided tape, an adhesive, or the like.

Of course, in addition to the above-described double-sided tape and adhesive, all known configurations used for lamination bonding may be employed.

And as shown in FIG. 8, the paper machine 3 includes a plurality of horizontal supports 31a for holding the skeleton in the horizontal direction and a plurality of vertical supports 31b for holding the skeleton in the vertical direction. It includes a lattice-shaped frame body 31 . And here, the horizontal direction means a direction in which it is transported, and the vertical direction means a direction perpendicular thereto and the same as the height direction.

And the plurality of vertical support (31b) is provided with a plurality of supply shafts 32 horizontally protruding so that the lamination object (film fabric (F)) can be hung and supplied, and the supply shaft 32 is a plurality of each supply shaft case. (33) is connected to each of the built-in powder brakes (not shown) are mounted.

The powder brake (not shown) connected to the supply shaft 32 is a well-known and customary technique, which appropriately holds the rotational force of the supply shaft in the process of transporting and supplying a laminating medium such as double-sided tape or protective paper, which is necessary for transport and supply. It plays a role in helping to keep the tension constant.

And when it is necessary to additionally laminate the protective paper on the laminated film which has been laminated, the supply may be performed by winding the protective paper on any one of the plurality of supply shafts 32 .

And a plurality of collection motors 35, each connected to a plurality of winding shafts 34 protruding horizontally so as to wind and collect derivatives such as release papers generated in the laminating process, are mounted on the horizontal support 31a at predetermined intervals. is placed.

Next, a cutting step of cutting the laminated laminated film is performed. In the case of the above-described cutting step, the cutting is performed according to the required processing specifications, and a detailed description thereof will be omitted since it may be variously performed with reference to a known technique.

And as shown in Figure 12, the lamination machine (3) is provided with a disk type blade (Disc Type Blade) (T3) capable of both half-knife and full-knife processing. Through the provision of the disk-type blade (T3), both half-cut and full-knife processing of films and tapes can be performed, and when a defective part of the edge part occurs in the above processing process, it is of course possible to cut them, so that it is completely automatic processing can be realized.

On the other hand, the first roller R1 and the second roller R2 need to apply a predetermined tension to the winding target in order to wind the film to be wound without play. And there is also a need to adjust the degree of tension added according to the work environment, the amount of the winding target is wound or the material of the winding target.

Accordingly, in order to realize this, the present invention rewinds and discharges a first roller (R1) on which a winding target is wound and disposed on one side and the winding target input by the first roller (R1), and the second is disposed on the other side. It further includes a tension adjusting device provided between the rollers (R2).

Here, the first roller R1 may be the input roller 11 , the second roller R2 may be the supply roller 211 , and the winding target may be the film fabric F.

As shown in FIG. 13 , the tension adjusting device includes a guide frame T2 and a tension roller R3 on which both ends of a central axis R31 are supported on the guide frame T2 .

In addition, the guide frame T2 includes a guide rod T20 on which the central axis R31 is guided along the longitudinal direction of the guide frame T2. Thus, the tension roller R3 can move along the guide rod T20.

Accordingly, the first area corresponding to the area where the winding target spans from the first roller R1 to the tension roller R3 and the winding target span from the tension roller R3 to the second roller R2. A tension angle, which is an angle formed by the second region corresponding to the region, can be adjusted.

The tension adjusting device is configured to reduce the tension angle by 10 degrees from the non-setting step corresponding to 180 degrees as an embodiment, so that the tension angle can be adjusted up to the ninth setting step corresponding to 90 degrees do.

Thus, the tension angle can be adjusted by 10 degrees from the first setting step in which the tension angle corresponds to 170 degrees to the ninth setting step in which the tension angle corresponds to 90 degrees. In addition, as the ninth setting step progresses, the tension can act to be greater.

In addition, the guide rod T20 includes a main rod formed in the longitudinal direction in the center, and one side sub-rod T21 extending outward from one side of the main rod and arranged in plurality with a predetermined separation distance; It is formed extending outward from the other side, and includes a sub-rod including a plurality of other-side sub-rods T22 arranged at a predetermined distance.

For example, when you want to adjust the tension angle from the first setting step on one side to the second setting step on the one side, the central axis R31 seated on the first sub-rod is separated from the first sub-rod on the one side and moved along the main rod. After making it, it can be seated on one side of the second sub-rod. In this case, as a result, the seating angle is changed from 170 degrees to 160 degrees. (Of course, in the case of the other side sub-rod T22, which will be described later, the tension angle is adjusted from the first setting step of the other side to the second setting step of the other side, and the tension angle is 175. It becomes possible to change from the figure to 165 degrees.)

And this one side sub-rod (T21) is composed of one side of the first sub-rod that can make the tension angle of 170 degrees to the one-side ninth sub-load that can make the tension angle of 90 degrees, and the other side sub-load (T22) has the tension angle. It consists of a first sub-rod on the other side that can make 175 degrees, and a ninth sub-rod on the other side that can make a tension angle of 95 degrees.

Here, the difference between the one sub-rod T21 and the other sub-rod T22 is that they are alternately arranged in a zigzag manner. By being staggered in this way, the interval of the tension angle can be more finely adjusted, and there is an advantage that it can be implemented by integrating it within the guide frame T2 within a limited range.

Because if each of the sub-rods T21 and the other sub-rods T22 are not configured to extend in different directions on one side and the other side, but are configured to face the same direction, the tension angle is lowered to 5 degrees or less. This is because the volume of the guide frame T2 is inevitably increased in order to perform fine adjustment.

In addition, the sub-rod is composed of an entry part T211 formed at a point connected to the main rod and a fixing part T212 connected at the entry part T211 and bent in the direction of the main rod.

In addition, the fixing part T212 further includes a seating space corresponding to a space in which the central axis R31 is seated, and the width of the fixing part T212 is gradually reduced toward the seating space. This is to stably seat the central axis R31 in the seating space.

And the central axis (R31) further includes a seating portion to be seated in the seating space, and the seating roller further includes a separation prevention unit (R32) on the inside and outside of the seating portion. The separation prevention unit (R32) has a cylindrical shape and also serves to guide the central axis (R31) when changing each setting step while contacting the guide frame (T2).

And one end of the central axis (R31) further includes a handle (T50), wherein the characteristic point is that the handle (T50) includes a grip portion (T51) formed to be bent inwardly of the handle (T50), That is, the tangent line of the center of the curved portion and the longitudinal direction of the guide rod T20 may be formed to be perpendicular. Through this, it has the advantage that it is easy to guide the central axis R31 along the guide rod T20.
