Since the second film transfer roller unit 340 has the same configuration as the first film transfer roller unit 260, a detailed description will be omitted.

The meandering prevention unit 400 serves to adjust the transfer direction of the metal film 10 ′ in a forward direction while passing through the longitudinal cutting unit 200 and the film speed control unit 300. FIG. 8 is a perspective view showing the configuration of the meandering prevention unit 400, and FIG. 9 is an exemplary view showing a process in which the meandering prevention unit 400 adjusts the direction of the metal film.

As shown, the meandering prevention unit 400 includes a swivel plate 410 provided to be swiveled with respect to the base plate 900, and a pair of third side frames vertically provided on both sides of the swivel plate 410 ( 420, a plurality of fourth film guide rollers 430 and fourth film guide rollers 430 provided so as to be idle on the third side frame 420 to form a transfer path of the metal film 10' The transfer direction detection roller 440 disposed at the rear end of the, and a pair of film position detection sensors 450 and 450a provided at both ends of the transfer direction detection roller 440 to detect the transfer direction of the metal film 10' , And a swivel driving unit 460 for rotating the swivel plate 410 forward and backward according to the detection result of the pair of film position detection sensors 450 and 450a.

The swivel plate 410 is swively coupled to the base plate 900 by a swivel shaft 461. The metal film 10 ′ is transferred by the second film transfer roller unit 340 and transferred to the third film transfer roller unit 520 of the film supply unit 500.

The plurality of fourth film guide rollers 430 form a transfer path of the metal film 10 ′ between the second film transfer roller unit 340 and the third film transfer roller unit 520. The transfer direction detecting roller 440 is disposed toward the film supply unit 500 to guide the metal film 10 ′ toward the third film transfer roller unit 520.

A pair of film position detection sensors 450 and 450a are provided at both ends of the transfer direction detection roller 440 and sense the pressure applied to both ends to detect the transfer direction of the metal film 10'. For example, when the same pressure is applied to the pair of film position sensing sensors 450 and 450a, it may be determined that the metal film 10 ′ is transported in the forward direction through the central region of the transport direction sensing roller 440. On the other hand, when the pressure of the film position sensing sensor 450 located on the right side of the transport direction sensing roller 440 is greater than the film position sensing sensor 450a located on the left, the metal film 10' is biased to the right. It can be judged to be transferred.

The swivel driving unit 460 rotates the swivel plate 410 forward and backward according to the detection result of the pair of film position detection sensors 450 and 450a to adjust the metal film 10' to be supplied to the film supply unit 500 in the forward direction. .

Let 410 swivel.

For example, as shown in (a) of FIG. 9, when the metal film 10' is transferred to the right side of the forward direction (X), that is, the right side of the transfer direction detecting roller 440 , The pressure of the film position sensing sensor 450 located on the right side is measured greater than that of the film position sensing sensor 450a located on the left side. In this case, the transfer direction must be adjusted so that the metal film 10' deflected to the right is moved to the left and transferred in the forward direction.

To this end, as shown in (b) of FIG. 9, the second direction pressurizing cylinder 465 is driven to increase the length of the second cylinder shaft 466, thereby swiveling the swivel plate 410 in a counterclockwise direction. Thereby, the fourth film guide roller 430 and the transfer direction detecting roller 440 provided in the third side frame 420 coupled to the swivel plate 410 are moved to the left together, and the metal film 10' The moving direction can be adjusted in the forward direction (X).

Here, the swivel angle of the swivel plate 410 may be calculated by a difference between the pressure values measured by the pair of film position sensors 450 and 450a.

For example, when transferring the metal film 10' of the first width (ℓ1), vacuum pressure is formed only in the first area (A), and the metal film 10' of the second width (ℓ2) is transferred. In this case, a vacuum pressure is also formed in the second region B, and when the metal film 10 ′ having a third width L3 is transferred, a vacuum pressure is also formed in the third region C.

A vacuum pressure hose (not shown) for applying vacuum pressure is coupled to the lower part of the fixed table 620 and the descending table 630 for each area, and selectively according to the width of the metal film 10' under the control of the operator. Vacuum pressure is applied.

A lower cutter 623 is formed at an upper end of one side of the fixed table 620 in the width direction. The lower cutter 623 is disposed in the corner region of the fixed table 620 and cuts the metal film 10' in the width direction together with the upper cutter 650 descending from the top.

The lowering table 630 is provided to be lowered in association with the lowering of the upper cutter 650. As shown in FIG. 15, the descending table 630 is disposed to be spaced apart from the upper end of the lower frame 610 at a predetermined distance d. The descending table 630 maintains the same height as the fixed table 620 when the metal film 10' is supplied from the fixed table 620, and the upper cutter 650 is removed after the metal film 10' is supplied. It descends and when it touches the metal film 10', it interlocks with it and descends together.

The descending table 630 descends to a position reaching the upper end of the lower frame 610. To this end, a plurality of table lowering cylinders 633 are provided in the width direction below the lowering table 630. The table descending cylinder 633 is fixed to the lower frame 610, and a descending cylinder rod 633a is coupled therein to be movable vertically. Inside the table descending cylinder 633, a moving distance in which the descending cylinder rod 633a is moved up and down is formed to correspond to the distance d between the descending table 630 and the lower frame 610.

The descending table 630 descends together with the upper cutter 650 to prevent the metal film 10 ′ from being wrinkled during cutting. When the metal film 10' is horizontally positioned across the fixed table 620 and the descending table 630, and the upper cutter 650 descends and cuts between them, it is cut by the downward pressure of the upper cutter 650 The area is moved downward and wrinkles may occur.

When the descending table 630 descends, the metal sheet 10" cut by the upper cutter 650 is also descended, so that wrinkles in the cutting area can be prevented. In addition, the occurrence of bur can be reduced. have.

The vertical frame 640 is fixedly coupled to the lower frame 610 as shown in FIGS. 11 and 12. The fixed table 620 and the descending table 630 are disposed adjacent to each other on both sides of the vertical frame 640.

Here, the upper cutter 650 is disposed to be spaced apart from the lower cutter 623 by a predetermined distance in order to reduce the occurrence of bur and extend the service life. That is, as shown enlarged in FIG. 16, the upper cutter 650 is coupled to the cutter frame 651 so as to be spaced apart from the lower cutter 623 in a range of 5 μm to 15 μm while the upper cutter 650 is lowered.

Although the spacing between the upper cutter 650 and the lower cutter 623 is fine, since the thickness of the metal film 10' exists, the upper cutter 650 is pushed back by the spaced interval, so that the upper cutter 650 and the lower cutter 623 ) Will not be in direct contact. For example, in the case of the metal film 10 ′ composed of Invar 100 μm, PSA 30 μm, and PET 50 μm, the total thickness is 180 μm, which is larger than the distance between the upper cutter 650 and the lower cutter 623.
