Hereinafter, a method of peeling the second film (F2) from the first film (F1) will be described with reference to the drawings.

First, as shown in FIG. 2, the multilayer film (F) is seated on the seating plate 12 so that the rear end of the multilayer film (F) is interposed between the attachment roller 32 and the seating plate 12. More specifically, the multilayer film (F) is mounted on the seating plate 12 so that the first film (F1) faces the seating plate (12) and the second film (F2) is exposed to the outside. In addition, the multilayer film (F) is preferably mounted on the seating plate 12 so that the longitudinal direction of the multilayer film (F) and the Y-axis direction are parallel, but the present invention is not limited thereto.

Next, the controller 40 drives the first vacuum pump 14 of the fixing unit 10 to apply vacuum pressure to the first suction holes 12a of the seating plate 12. Then, the first film (F1) is. It can be fixed to the seating plate 12 by being vacuum-sucked by vacuum pressure applied to the first suction holes 12a of the seating plate 12.

Thereafter, the controller 40 drives the roller swing member 26 so that the peeling roller 22 is disposed so that the rotation axis of the peeling roller 22 makes a predetermined angle with the width direction of the multilayer film F. The peeling roller 22 coupled to the 1 roller drive member 24 and the first roller drive member 24 is swing around the Z axis.

Next, the controller 40 drives the first conveyor 28 so that the peeling adhesive layer 22a of the peeling roller 22 comes into contact with one edge of the second film F2, thereby forming the peeling roller 22. ) is transferred. Then, one edge of the second film (F2) is attached to the peeling adhesive layer (22a) of the peeling roller (22).

Thereafter, as shown in FIG. 4, the controller 40 controls the first film F1 while one edge of the second film F2 attached to the peeling roller 22 flows along the peeling roller 22. The first roller drive member 24 is driven to rotate the peeling roller 22 by a predetermined angle about the rotation axis so that peeling begins from the adhesive layer A toward the attachment roller 32, and the roller swing member (26) is driven to swing the first roller drive member 24 and the peeling roller 22 coupled to the first roller drive member 24 about the Z axis. That is, the second film (F2) is peeled from the first film (F1) starting from one edge.

In addition, as shown in FIGS. 4 to 7, the controller 40 controls the second film (F2), at one edge of which has begun to peel off from the adhesive layer (A) of the first film (F1), in the -Y-axis direction. The roller swing member 26 and the first roller drive member 24 coupled to the roller swing member 26 are transported in the -Y-axis direction by driving the first transporter 28 so that the roller swing member 26 and the first roller drive member 24 coupled to the roller swing member 26 can be gradually separated. . At the same time, as shown in FIG. 6, the controller 40 controls the boundary between the portion attached to the first film F1 and the portion peeled from the first film F1 among the entire area of the second film F2. Drive the roller swing member 26 so that the corresponding boundary line B is parallel to the attachment roller 32 to form a peeling roller coupled to the first roller drive member 24 and the first roller drive member 24 ( 22) Swing a predetermined angle around the Z axis. At this time, as shown in FIG. 7, the controller 40 drives the first roller drive member 24, the roller swing member 26, and the first conveyor 28 to attach the attachment roller 32 and Peeling off the remaining portion of the second film (F2) excluding the rear end portion of the second film (F2) interposed between the seating plates 12 (hereinafter referred to as 'peeling area (F2e) of the second film (F2)') However, the lower part of the peeling area (F2e) of the second film (F2) is caught by the attachment roller 32, and the upper part of the peeling area (F2e) of the second film (F2) is the inclined surface of the tension applying member (34). The peeling area (F2e) of the second film (F2) is peeled so that it is seated at (34a).

Next, the controller 40 drives the second vacuum pump 35 of the attachment unit 30 to apply vacuum pressure to the second suction holes 34b of the tension applying member 34. Then, the upper part of the peeling area (F2e) of the second film (F2) seated on the inclined surface (34a) of the tension application member (34) is vacuum-sucked by the second suction holes (34b) of the inclined surface (34a). . Here, the controller 40 slides along the inclined surface 34a in a state in which the peeling area F2e of the second film F2 is vacuum-sucked by the second suction holes 34b of the inclined surface 34a. The second vacuum pump 35 is driven to apply a predetermined vacuum pressure to the second suction holes 34b of the inclined surface 34a. That is, the first vacuum pump 14 of the fixing unit 10 applies relatively strong vacuum pressure to the first suction hole of the seating plate 12 in order to fix the first film F1 in a state where it cannot flow. On the other hand, the second vacuum pump 35 of the attachment unit 30 has the second film F2 vacuum-adsorbed by the second suction holes 34b of the inclined surface 34a. A relatively weak vacuum pressure is applied to the second suction holes 34b of the inclined surface 34a so that the furnace can slide along the inclined surface 34a.

Figures 8 to 10 are diagrams for explaining a method of reattaching the second film to the first film using the curl removal device for multilayer film shown in Figure 2.

Hereinafter, with reference to FIGS. 8 to 10, the second film (F2) peeled from the adhesive layer (A) of the first film (F1) is reattached to the adhesive layer (A) of the first film (F1). Let me explain the method.

As shown in FIGS. 8 to 10, the controller 40 drives the second transfer machine 36 to transfer the attachment roller 32 and the tension application member 34 in the +Y-axis direction, and The roller drive member 33 is driven to rotate the attachment roller 32 around the rotation axis, and the second vacuum pump 35 is driven to apply vacuum pressure to the second suction holes 34b of the inclined surface 34a. Authorize.

Then, the attachment roller 32 moves in the Y-axis direction and sequentially presses the peeled area F2e of the second film F2 in the Z-axis direction in the contact order to reattach it to the first film F1.

However, the area seated on the inclined surface 34a among the peeling areas F2e of the second film F2 slides along the inclined surface 34a while being vacuum-adsorbed to the second suction holes 34b of the inclined surface 34a. It is moved. Then, the peeling area F2e of the second film F2 is attached to the first film F1 in a state in which a predetermined tension is applied by the vacuum pressure provided from the second vacuum pump 35 of the attachment unit 30. can be reattached to Accordingly, the peeled area (F2e) of the second film (F2) can be reattached to the adhesive layer (A) of the first film (F1) in a flat state without wrinkles.

Meanwhile, as shown in FIG. 8, one edge of the second film F2 attached to the peeling adhesive layer 22a of the peeling roller 22 is a peeling area F2e of the second film F2. In the process of reattaching to the first film (F1), the adhesive layer for peeling (22a) is naturally peeled off by the pressing force applied to the peeling area (F2e) of the second film (F2) by the attachment roller (32). However, it is not limited to this, and the roller swing member 26 and the first conveyor 28 are used to separate the peeling area F2e of the second film F2 from the first film F1 by the attachment roller 32. When reattached, the peeling roller 22 can be transferred so that one edge of the second film F2 is more naturally peeled off from the peeling adhesive layer 22a.

As above, the curl removal device 1 for a multilayer film peels the second film (F2) from the adhesive layer (A) of the first film (F1) between the second film (F2) and the first film (F1). After removing the stress acting on, the second film (F2) can be reattached to the adhesive layer (A) of the first film (F1) in a straightened state. Through this, the curl removal device 1 for a multilayer film can remove the curl from the curled multilayer film F, thereby restoring the curled multilayer film F to a good product.

However, with the rear end of the multilayer film (F) interposed between the attachment roller 32 and the seating plate 12, the peeling area (F2e) of the second film (F2) is peeled and reattached, so that the multilayer film Even if the curl occurring in the multilayer film (F) is removed using the curl removal device (1), the curl occurring at the rear end of the multilayer film (F) may still remain. Accordingly, when curls still remain at the rear end of the multilayer film (F), the multilayer film (F) is turned in the opposite direction so that the front end of the multilayer film (F) is interposed between the attachment roller 32 and the seating plate 12. By performing the curl operation again in this state, the remaining curl formed at the rear end of the multilayer film (F) can be removed.

The above description is merely an illustrative explanation of the technical idea of the present invention, and various modifications and variations will be possible to those skilled in the art without departing from the essential characteristics of the present invention.

Accordingly, the embodiments disclosed in the present invention are not intended to limit the technical idea of the present invention, but are for illustrative purposes, and the scope of the technical idea of the present invention is not limited by these embodiments.
