As shown in fig. 5 (in a state where the first shrink film 7 is fed), the first shrink film 7 is set on the first feeding device 5 (as shown in fig. 1), and the first shrink film 7 is supplied to the first film bonding device 1 and the transfer device 3, and the first shrink film 7 is transported on the first film bonding stage 11 and the transfer stage 31. In this embodiment, the supply is carried out by the first shrink film 7; however, the present invention is not limited thereto. In other embodiments of the invention, the second shrink film 8 may be fed first.

In addition, the motor 10 (shown in fig. 1) drives the guide wheel 32 to rotate, so that the first shrink film 7 is rapidly rolled to perform feeding. Therefore, the third upper rotating plate 33 and the third lower rotating plate 34 on the transferring device 3 are in an open state, and the first upper rotating plate 13 and the first lower rotating plate 14 of the first film receiving device 1 are also in an open state, so as to allow slight vibration of the first shrink film 7 during fast rolling, keep smooth feeding of the first shrink film 7, or prevent damage of the first shrink film 7. In the present embodiment, the third upper rotating plate 33 and the third lower rotating plate 34 or the first upper rotating plate 13 and the first lower rotating plate 14 are opened by 180 degrees; however, in another embodiment of the present invention, the opening angle of the third upper rotating plate 33 and the third lower rotating plate 34 or the first upper rotating plate 13 and the first lower rotating plate 14 is not limited thereto, as long as the movement of the shrink film is not affected.

Meanwhile, as shown in fig. 4(C) and 5, the second film joining device 2 is in a ready-to-join state, which is ready to wait for a film joining operation, and thus, the second shrink film 8 is set on the second supply device 6 (as shown in fig. 1), and the second shrink film 8 is supplied to the second film joining table 21 of the second film joining device 2, and one end of the second shrink film 8 is disposed corresponding to the second film joining end 21a (as shown in fig. 4 (B)), and the second shrink film 8 is passed through and protruded between the second upper rotating plate 23 and the second lower rotating plate 24 (as shown in fig. 4 (B)). In addition, since the shrink film is a flattened cylindrical plastic film, the first film layer 8a and the second film layer 8b can be formed by cutting both sides of the second shrink film 8, wherein the first film layer 8a of the second shrink film 8 is adsorbed on the second upper adsorption element 231 (as shown in fig. 4 (a)), the second film layer 8b of the second shrink film 8 is adsorbed on the second lower adsorption element 241 (as shown in fig. 4 (a)), and the surfaces of the second upper rotating plate 23 and the second lower rotating plate 24 face the third film connecting end 31a (as shown in fig. 1) of the transfer stage 31, respectively. Next, since the first film layer 8a and the second film layer 8b of the second shrink film 8 are only partially attached to the tapes 232 and 242, the portions of the tapes 232 and 242 not covered by the first film layer 8a and the second film layer 8b of the second shrink film 8 can be used for joining with the first shrink film 7. In this embodiment, the first shrink film 7 is joined to the second shrink film 8 by means of adhesive tapes 132, 142, 232, 242; however, the present invention is not limited thereto. In other embodiments of the present invention, the first shrink film 7 and the second shrink film 8 may be joined by other means. For example, bonding may be by glue, welding, or other film bonding.

As shown in fig. 6 (the state that the cutting element 35 cuts the first shrink film 7), when the first shrink film 7 has a predetermined length left on the first feeding device 5 (i.e. the first shrink film 7 is about to be used), the motor 10 (shown in fig. 1) is stopped and ready for film splicing. Here, the automatic film splicing apparatus further includes a detecting unit (not shown) for detecting the amount of the first shrink film 7 or the second shrink film 8 remaining on the first supply device 5 or the second supply device 6. The type of the detecting unit is not limited, and may be an optical detecting unit or other detecting units. When the film joining is to be performed, the third upper rotating plate 33 and the third lower rotating plate 34 on the transferring device 3 are faced to each other (i.e. in a closed state), and the first upper rotating plate 13 and the first lower rotating plate 14 of the first film joining device 1 are also in a closed state, so that the first shrink film 7 is sandwiched between the third upper rotating plate 33 and the third lower rotating plate 34 and between the first upper rotating plate 13 and the first lower rotating plate 14, and the first shrink film 7 can be effectively fixed, and then the cutting element 35 is used to cut the first shrink film 7 (as shown in fig. 2 (C)), so as to form a uniform and neat cut surface. In the present embodiment, the cutting element 35 is a blade; however, the present invention is not limited thereto. In other embodiments of the present invention, the cutting element 35 may be scissors, a saw blade, or any suitable element for cutting shrink film.

As shown in fig. 7 (the transfer device 3 is moved so that the transfer stage 31 is disposed corresponding to the second film receiving stage 21 of the second film receiving device 2), after the first shrink film 7 is cut by the cutting device 35, the third upper rotating plate 33 is turned over, and the third lower rotating plate 34 is kept in place, so that the third lower rotating plate 34 can support the first shrink film 7 to prevent the first shrink film 7 from falling downward. Next, the transfer device 3 is moved, and the transfer stage 31 is provided corresponding to the second film bonding stage 21 of the second film bonding device 2. In the present embodiment, the third upper rotating plate 33 and the third lower rotating plate 34 are opened by 90 degrees; however, the present invention is not limited thereto. In other embodiments of the present invention, the position of the third upper rotating plate 33 and the third lower rotating plate 34 does not affect the shrink film joint, or can support the shrink film.

As shown in fig. 4(C) and 8 (the first layer 8a of the second shrink film 8 is bonded to the first shrink film 7), the second upper rotating plate 23 is turned over so that the adhesive tape 232 fixed to the second upper rotating plate 23 is bonded to the first shrink film 7, thereby simultaneously bonding the first layer 8a of the second shrink film 8 bonded to the adhesive tape 232 to the first shrink film 7. In addition, the third lower rotating plate 34 can effectively support the first shrink film 7, so that the jointing quality is improved, and the incomplete jointing condition is prevented.

As shown in fig. 4C and 9 (the second film layer 8b of the second shrink film 8 is bonded to the first shrink film 7), the third lower rotating plate 34 is turned over so that the third upper rotating plate 33 and the third lower rotating plate 34 are opened, and the second film layer 8b of the second shrink film 8 is bonded to the first shrink film 7. In the present embodiment, the third upper rotating plate 33 and the third lower rotating plate 34 are opened by 180 degrees; however, the present invention is not limited thereto. In other embodiments of the present invention, the position of the third upper rotating plate 33 and the third lower rotating plate 34 does not affect the shrink film bonding. Then, the second upper rotating plate 23 is kept in place, thereby providing a supporting force required for bonding the second film layer 8b of the second shrink film 8, which is helpful for improving the bonding quality. Subsequently, the second lower rotating plate 24 is turned over so that the second upper rotating plate 23 is opposed to the surface of the second lower rotating plate 24, and the adhesive tape 242 fixed to the second lower rotating plate 24 is bonded to the first shrink film 7, thereby simultaneously bonding the second film layer 8a of the second shrink film 8 attached to the adhesive tape 242 to the first shrink film 7. Since the first film layer 8a and the second film layer 8b of the second shrink film 8 have been respectively joined with the first shrink film 7, the second shrink film 8 is successfully joined to the first shrink film 7.

As shown in fig. 10 (in a state where the second shrink film 8 is fed), the second upper rotating plate 23 and the second lower rotating plate 24 are turned over to open the second upper rotating plate 23 and the second lower rotating plate 24, and the rotation speed of the guide roller 32 is restored by the motor 10 (shown in fig. 1) to feed the second shrink film 8. In this embodiment, the included angle between the second upper rotating plate 23 and the second lower rotating plate 24 is 180 degrees, but the present invention is not limited thereto, as long as the positions of the second upper rotating plate 23 and the second lower rotating plate 24 do not affect the movement of the shrink film. Moreover, when the second shrink film 8 is ready to be used, the second shrink film 8 can be bonded with the first shrink film 7 in the same manner by simple replacement according to the steps, so that the effect of automatically connecting the films is achieved, and the method has the advantages of reducing the production cost, improving the yield, improving the qualification rate, firmly bonding the shrink films or keeping the shrink films clean and the like.

Although the present invention has been described by way of examples, it is to be understood that many other modifications and variations are possible without departing from the spirit of the invention and the scope of the claims.
