As shown in FIGS. 6 to 7 , the film lift 500 is installed to be movable up and down on the upper part of the main body 100 , and may be inserted into the insertion groove 110 . The film lift 500 is installed to be biased in the direction in which the unwinder 200 is located based on the cutting position of the film by the cutting guide 400 . That is, as shown in FIG. 10 , the cutting position of the film by the cutting guide 400 is located on the left side of the film lift 500 . Accordingly, as shown in FIG. 7 , the film lift 500 lifts the cut end of the consumable film F1 to provide a space to position the tape for connecting the two different films on the upper body 100 . secure

The first stopper 610 fixes the film between the unwinder 200 and the cutting guide 400 . The second stopper 620 fixes the film between the rewinder 300 and the film lift 500 . The film moves to the lower portions of the first stopper 610 and the second stopper 620 , and the first stopper 610 or the second stopper 620 may descend to fix the film, if necessary.

The first support roller 710 is mounted on the main body 100 , is positioned between the unwinder 200 and the first stopper 610 , and supports the film unwound from the unwinder 200 . The second support roller 720 is mounted on the main body 100 , is positioned between the second stopper 620 and the rewinder 300 , and supports the film wound by the rewinder 300 . The positions of the first support roller 710 and the second support roller 720 may be adjusted according to the working conditions and the tension applied to the film.

Each component of the film cutting connection device according to an embodiment of the present invention is operated by an operator manipulating the control panel installed on the main body 100 . And the cutting guide 400, the film lift 500, the first stopper 610 and the second stopper 620 moving up and down may use a linear motor or a cylinder device as a driving means.

Next, a method for replacing and connecting a film roll using a film cutting and connecting device according to an embodiment of the present invention will be described.

In the following description, the film is divided into a consumable film (F1) that is used first and a replacement film (F2) to be newly inserted and connected.

As shown in FIG. 2 , the consumable film F1 is unwound in a state in which the film roll of the consumable film F1 is coupled to the unwinder 200 , and the consumable film F1 passes through the upper part of the body 100 . It is wound on the rewinder 300 . At this time, the cutting guide 400 , the first stopper 610 , and the second stopper 620 are raised, and the film lift 500 is inserted into the insertion groove 110 . As shown in FIG. 4( a ), when the consumable film F1 is all unwound from the unwinder 200 , the unwinder 200 and the rewinder 300 are stopped, the first stopper 610 , the second 2 The stopper 620 and the cutting guide 400 descend to fix the consumable film F1. Thereafter, the shaft 210 is rotated horizontally to couple the film roll of the replacement film F2.

In the state in which the replacement film F2 is fixed as described above, the operator cuts the consumable film F1 along the cutting guide 400 as shown in FIG. 4(b), and a first stopper 610 Remove the part of the consumable film (F1) separated after cutting by raising it.

Then, as shown in Figure 5 (a), the cutting guide 400 rises, the operator pulls the replacement film (F2) to the first stopper 610 and the cutting guide 400 to the lower portion of the replacement film (F2) (F2) ) is pushed in. Again, as shown in FIG. 5(b), the cutting guide 400 and the first stopper 610 descend to fix the replacement film F2. In a state in which the replacement film F2 is fixed, the operator cuts the replacement film F2 along the cutting guide 400 and removes a portion of the replacement film F2 separated after cutting. Since the consumable film F1 and the replacement film F2 are cut at the same cutting position guided by the cutting guide 400, the cutting side end of the consumable film F1 and the cutting side end of the replacement film F2 are exactly each other will come into contact

As shown in Fig. 6 (a), the cutting guide 400 rises first in a state where the cutting side end of the consumable film F1 and the cutting side end of the replacement film F2 are in contact with each other. And as shown in Figure 6 (b), the film lift 500 lifts the cut-side end of the consumable film (F1) while rising. The operator directly lifts the cut-side end of the replacement film (F2) to secure a space for positioning the tape at a position where the consumable film (F1) and the replacement film (F2) are connected. And the operator pulls the tape fixed to the tape hanger 120 and places it on the upper part of the main body 100 . At this time, both sides of the tape are fixed to the upper part of the main body 100 by the magnetic fixing means 130 . And the film lift 500 descends, and the connection part of the consumable film F1 and the replacement film F2 is attached to the tape. After the tape is attached to the lower part of the connection part between the consumable film (F1) and the replacement film (F2), another tape is placed on the upper part of the connection part of the consumable film (F1) and the replacement film (F2) to cover the consumable film (F1) and the replacement film ( Attach the tape to both upper and lower sides of the connecting part of F2). And the operator cuts the part protruding from both sides of the consumable film (F1) and the replacement film (F2) of the tape connecting the consumable film (F1) and the replacement film (F2).

Then, as shown in FIG. 8 , the first stopper 610 and the second stopper 620 rise, and as the unwinder 200 and the rewinder 300 operate, the consumable film connected by the tape T (F1) and the replacement film (F2) is wound by the rewinder (300).
