Description

Technical Field

[0001] The present invention relates to an automatic film splicing device and an automatic film splicing method using the same. Background Art

[0002] Known film splicing devices require manual attention at all times to monitor the inventory of the film material and rely on experience to judge whether the film material needs to be replaced. In addition, before the film material is about to run out, the production line must be manually stopped first, and then the new film material is replaced manually. The production line can only be restarted for production after the old film material and the new film material are joined together. In addition, during the process of replacing the film material, it is necessary to rely on manual labor to cut the film material and the tape of an appropriate length, then manually align the front end of the new film material with the tail end of the old film material, and then join them with the tape.

[0003] However, in the known technology, since it is necessary to monitor the usage of the film material at all times to prevent the production line from stopping, the labor cost will increase. Secondly, since the speed of manually replacing the film material is slow and the operation time for stopping the production line to replace the film material is long, a huge business loss will be caused. In addition, since manual alignment and fitting of the old and new film materials are relied on, each joining of the old and new film materials may result in deviation, making it difficult to quickly and stably fit the two rolls of film materials, and there may also be a problem of contaminating the film material during the manual fitting process. In addition, in the known technology, the film materials to be joined are single-layer film materials, and it is difficult to apply the joining technology of single-layer film materials to double-layer film materials for joining. Therefore, the joining technology of double-layer film materials still needs to be further developed or improved. To sum up, using the known film splicing device may cause problems such as increased production costs, decreased productivity, reduced yield, inaccurate film joining, film contamination, or difficulty in joining double-layer film materials.

[0004] Therefore, it is urgent to propose a brand-new automatic film splicing device to eliminate or alleviate the above problems. Summary of the Invention

[0005] In view of this, the present invention proposes an automatic film splicing device to reduce production costs, improve productivity, increase yield, ensure the accurate joining of shrink films, or keep the shrink films clean.

[0006] To achieve the above object, according to the first form of the present invention, the automatic film connecting device of the present invention includes a film connecting table, a suction cup mechanism, a feeding mechanism, and a bonding unit supply mechanism. The film connecting table has a plurality of shrink film channels, and each of the plurality of shrink film channels has a first film connecting end. The plurality of shrink film channels may be arranged adjacent to each other, but the present invention is not limited thereto. For example, the plurality of shrink film channels may be arranged in an up-and-down stacked manner or side by side. In addition, each of the plurality of shrink film channels of the film connecting table may be provided with a corresponding number of shrink films. When feeding with one of the plurality of shrink films, the remaining plurality of shrink films are in a standby film connecting state. When the first shrink film remains a predetermined length, another one of the plurality of shrink films will be connected thereto to continue feeding. The automatic film connecting method will be described below.

[0007] In addition, the suction cup mechanism includes a first suction cup element and a second suction cup element, wherein the second suction cup element is arranged corresponding to the first suction cup element. Therefore, the first suction cup element and the second suction cup element can be turned over to open an angle (for example, 0 degrees to 180 degrees).

[0008] Secondly, the feeding mechanism includes a feeding table, two belt fixing elements, a belt, and a cutting unit. The feeding table has a second film connecting end, and the second film connecting end is arranged corresponding to the first film connecting end of one of the plurality of shrink film channels. Therefore, the feeding mechanism can receive the shrink film from one of the plurality of shrink film channels and convey the shrink film on the film connecting table and the feeding table. Here, the form of the shrink film may be a double-layer film material, but the present invention is not limited thereto, and it may also be a single-layer film material or a multi-layer film material. The two belt fixing elements are arranged at the second film connecting end of the feeding table, and there is a spacing between the two belt fixing elements, and the size of the spacing is arranged corresponding to the width of the shrink film. The belt is arranged on the two belt fixing elements, but the belt does not pass through the space between the two belt fixing elements, but leaves the space between the two belt fixing elements. The form of the belt may be a flat belt, a V-shaped belt, a round belt, a toothed belt, or any suitable form of belt, but the present invention is not limited thereto. The cutting unit is arranged corresponding to the spacing between the two belt fixing elements, so as to cut the shrink film from one of the plurality of shrink film channels. The cutting unit may be a blade, scissors, a saw blade, or any element suitable for cutting the shrink film, but the present invention is not limited thereto.

[0009] In addition, the joining unit supply mechanism is disposed adjacent to the suction cup mechanism and includes a first supply element and a second supply element. The first supply element is correspondingly disposed with the first suction cup element and provides a first joining unit to the first suction cup element. Therefore, the first shrink film and the first film layer of the second shrink film can be joined through the first joining unit on the first suction cup element. Similarly, the second supply element is correspondingly disposed with the second suction cup element and provides a second joining unit to the second suction cup element. Therefore, the first shrink film and the second film layer of the second shrink film can also be joined through the second film joining unit on the second suction cup element, and the second shrink film and the first shrink film are successfully connected.

[0010] In the automatic film joining device of the present invention, the suction cup mechanism may further include a first driving unit, which is connected to the first suction cup element and the second suction cup element, and enables the first suction cup element and the second suction cup element to be in an open state or a closed state. The open state is that there is an included angle between the first suction cup element and the second suction cup element (for example, between 20 degrees and 180 degrees, between 60 degrees and 180 degrees, or between 90 degrees and 180 degrees; in an embodiment of the present invention, it is substantially 180 degrees), and the closed state is that the included angle between the first suction cup element and the second suction cup element is substantially 0 degrees. The first driving unit may be a cylinder, a motor, or other suitable driving units, but the present invention is not limited thereto.

[0011] In the automatic film joining device of the present invention, the feeding mechanism further includes a first roller and a second roller, which are disposed at the second film joining end of the feeding table, but the present invention is not limited thereto. In addition, the first shrink film can pass between the first roller and the second roller, and the first roller and the second roller are used to maintain the stable supply of the first shrink film, but the present invention is not limited thereto.

[0012] In the automatic film joining device of the present invention, the feeding mechanism further includes a steering roller, which is disposed on the feeding table so that the first shrink film can be conveyed in a first conveying direction and then changed to be conveyed in a second conveying direction, and the first conveying direction is different from the second conveying direction, thereby changing the conveying direction of the first shrink film, but the present invention is not limited thereto. In addition, the steering roller is not limited to changing the conveying direction of the first shrink film. As long as one of the multiple shrink films is supplied to the steering roller, its conveying direction can also be changed. In addition, the first conveying direction may be the direction from the first film joining end to the second film joining end of one of the multiple shrink film channels, but the present invention is not limited thereto.

[0013] In the automatic film joining device of the present invention, the joining unit supply mechanism may further include a second driving unit, which enables the joining unit supply mechanism to move toward or away from the suction cup mechanism to respectively provide the first joining unit or the second joining unit to the first suction cup element or the second suction cup element, but the present invention is not limited thereto.

[0014] In the automatic film joining device of the present invention, the first supply element may include a first roller group, which is correspondingly arranged with the first suction cup element to supply a first joining unit disposed on the first roller group to the first suction cup element, wherein the adhesive surface of the first joining unit is adhered to the first roller group, but the present invention is not limited thereto. Additionally, the first supply element may further include a first cutting element, which is disposed adjacent to the first roller group to cut the first joining unit, but the present invention is not limited thereto.

[0015] In the automatic film joining device of the present invention, the second supply element may include a second roller group, which is correspondingly arranged with the second suction cup element to supply a second joining unit disposed on the second roller group to the second suction cup element, wherein the adhesive surface of the second joining unit is adhered to the second roller group, but the present invention is not limited thereto. Additionally, the second supply element may further include a second cutting element, which is disposed adjacent to the second roller group to cut the second joining unit, but the present invention is not limited thereto.

[0016] In the automatic film joining device of the present invention, the first supply element and the second supply element may be adjacently arranged, but the present invention is not limited thereto; for example, the first supply element and the second supply element may be arranged in a stacked manner up and down.

[0017] In the automatic film joining device of the present invention, the first joining unit and the second joining unit may be tapes respectively, but the present invention is not limited thereto. In addition, there is no special limitation on the means of joining the shrink film. For example, tapes, colloids, welding or other film material joining methods may be used for joining.

[0018] According to the second form of the present invention, the present invention further provides an automatic film joining method, including the following steps:

[0019] Step S1: Provide the automatic film joining device as described above.

[0020] Step S2: Supply a first shrink film to the feeding mechanism, and the first shrink film is conveyed on one of the plurality of shrink film channels and the feeding table.

[0021] Step S3: Arrange a second shrink film, and one end of the second shrink film is arranged corresponding to the first film joining end of another one of the plurality of shrink film channels, and this end of the second shrink film forms a first film layer and a second film layer after being sheared, wherein a belt is arranged between the first film layer and the second film layer.

[0022] Step S4: When the first shrink film supplied to the feeding mechanism remains a predetermined length, cut the first shrink film supplied to the feeding mechanism with a cutting unit.

[0023] Step S5: Move the feeding mechanism so that the second film joining end of the feeding table corresponds to the first film joining end of another one of the plurality of shrink film channels.

[0024] Step S6: Move the joining unit supply mechanism so that the first suction cup element and the second suction cup element of the suction cup mechanism respectively adsorb the first joining unit and the second joining unit.

[0025] Step S7: Move the suction cup mechanism so that the suction cup mechanism is correspondingly arranged with another one of the plurality of shrink film channels, and flip the first suction cup element and the second suction cup element so that the surfaces of the first suction cup element and the second suction cup element face each other, so as to join the first film layer and the second film layer of the second shrink film to the first shrink film through the first joining unit and the second joining unit respectively.

[0026] In the automatic film joining method of the present invention, the first film layer and the second film layer of the second shrink film can be joined to the first shrink film by any means. For example, they can be joined to the first shrink film by tape, colloid, welding or other film material joining methods.

[0027] The foregoing step S6 of the automatic film joining method of the present invention may include: arranging the adhesive surfaces of the first joining unit and the second joining unit on the first roller group and the second roller group respectively, making the first suction cup element and the second suction cup element respectively adsorb the opposite sides of the adhesive surfaces of the first joining unit and the second joining unit, and cutting the first joining unit and the second joining unit with the first cutting element and the second cutting element.

[0097] The following provides different embodiments of the present invention. These embodiments are used to illustrate the technical content of the present invention, rather than to limit the scope of rights of the present invention. A feature of one embodiment can be applied to other embodiments through appropriate modification, replacement, combination, and separation.

[0098] It should be noted that in the present invention, except as specifically indicated, ordinal numbers such as "first", "second", etc. are only used to distinguish multiple elements with the same name, and do not indicate the existence of a rank, level, execution order, or process order between them. A "first" element and a "second" element may appear in the same component together, or in different components separately. The existence of an element with a larger ordinal number does not necessarily mean the existence of another element with a smaller ordinal number.

[0099] In the present invention, except as specifically indicated, the so-called feature A "or" (or) or "and / or" (and / or) feature B means that A exists alone, B exists alone, or A and B exist simultaneously; the so-called feature A "and" (and) or "and" (and) or "and" (and) feature B means that A and B exist simultaneously; the so-called "including", "comprising", "having", "containing" means including but not limited to this.

[0100] In addition, in the present invention, terms such as "upper", "lower", or "between" are only used to describe the relative positions between multiple elements, and can be extended in interpretation to include cases of translation, rotation, or mirroring.

[0101] In addition, in the present invention, except as specifically indicated, the statement that "one element is on another element" or a similar statement does not necessarily mean that the element contacts the other element.

[0103] Figure 2 A back three-dimensional schematic diagram showing an automatic film connecting device according to an embodiment of the present invention.

[0104] Such as Figure 1 And Figure 2As shown, the automatic film connecting device 100 of the present embodiment includes a film connecting table 1, a suction cup mechanism 2, a feeding mechanism 3, a bonding unit supply mechanism 4, and a cabinet 5. Among them, the film connecting table 1 is disposed on the tabletop 55 of the cabinet 5 and has a plurality of shrink film channels 10. The plurality of shrink film channels 10 respectively have a first film connecting end 10a. The first shrink film 11, the second shrink film 12, and the shrink films 13, 14, 15, 16 are respectively between the plurality of shrink film channels 10 and the film connecting table 1. Therefore, the stability of the first shrink film 11, the second shrink film 12, and the shrink films 13, 14, 15, 16 during the conveying process can be ensured through the plurality of shrink film channels 10. For example, when feeding with the first shrink film 11, the remaining second shrink film 12 and the shrink films 13, 14, 15, 16 are in a standby film connecting state. When the first shrink film 11 remains a predetermined length, one of the second shrink film 12 and the shrink films 13, 14, 15, 16 will be connected to the first shrink film 11 to continue feeding. As for the feeding situations of the second shrink film 12 and the shrink films 13, 14, 15, 16 are similar to that of the first shrink film 11 and will not be elaborated here. In addition, in the present embodiment, optionally, the first shrink film 11, the second shrink film 12, and the shrink films 13, 14, 15, 16 are fed in sequence from left to right or from right to left; however, the present invention is not limited thereto. Hereinafter, the case where the first shrink film 11 is fed first and then the first shrink film 11 is bonded to the second shrink film 12 will be described; and the automatic film connecting method will be described below.

[0105] In the present embodiment, the plurality of shrink film channels 10 are arranged side by side; in another embodiment, the plurality of shrink film channels 10 may be arranged in an up-and-down stacked manner. In addition, in the present embodiment, the plurality of shrink film channels 10 have six shrink film channels 10, and the six shrink film channels 10 of the film connecting table 1 may be respectively provided with the corresponding number of the first shrink film 11, the second shrink film 12, and the shrink films 13, 14, 15, 16; however, the present invention is not limited thereto.

[0106] Secondly, the tabletop 55 of the cabinet 5 is provided with a first track 51, a second track 52, a third track 53, and two belt fixing frames 54, and the first shrink film 11, the second shrink film 12, and the shrink films 13, 14, 15, 16 can be stored in the cabinet 5 (as Figure 2As shown in the figure, in one embodiment, the first shrink film 11, the second shrink film 12, and the shrink films 13, 14, 15, and 16 are each a double-layer film material, but are not limited thereto. In addition, the belt 33 is disposed on two belt fixing elements 32 of the feeding mechanism 3 (as shown in FIG. 5(A)), and is fixed to the tabletop 55 of the cabinet 5 by rollers 541 disposed on two belt fixing frames 54, wherein the two belt fixing frames 54 are correspondingly arranged with the two belt fixing elements 32 of the feeding mechanism 3. Since the two belt fixing frames 54 are adjacent to the first film receiving end 10a of the film receiving table 1, the belt 33 can pass through between the first film layer and the second film layer of the sheared first shrink film 11, second shrink film 12, and shrink films 13, 14, 15, 16 (as Figure 11 shown) (i.e., the first shrink film 11, the second shrink film 12, and the shrink films 13, 14, 15, 16 are each a double-layer film material), and support the first shrink film 11, the second shrink film 12, and the shrink films 13, 14, 15, 16. In the present embodiment, the suction cup mechanism 2 is disposed between the second track 52 and the third track 53, and the feeding mechanism 3 is disposed between the first track 51 and the third track 53, and the suction cup mechanism 2 and the feeding mechanism 3 can move along the long axis direction L; however, the present invention is not limited thereto.

[0107] Figures 3(A) to 3(B) A perspective view of a suction cup mechanism showing an embodiment of the present invention.

[0108] As shown in FIG. 3(A) (the first suction cup element 23 and the second suction cup element 24 are in the open state), the suction cup mechanism 2 includes a first driving unit 21, a support column 22, a first suction cup element 23, a second suction cup element 24, and a suction cup carrier 25. Among them, the support column 22 is disposed on the suction cup carrier 25 and is connected to the first driving unit 21. The first driving unit 21 has a first arm 211 and a second arm 212, and the first suction cup element 23 and the second suction cup element 24 are respectively disposed on the first arm 211 and the second arm 212 of the first driving unit 21, and the first suction cup element 23 and the second suction cup element 24 are correspondingly arranged. Therefore, driving the first driving unit 21 can flip the first arm 211 and the second arm 212, and further make the first suction cup element 23 and the second suction cup element 24 in the open state. When the first suction cup element 23 and the second suction cup element 24 are in the open state, the first suction cup element 23 and the second suction cup element 24 can respectively adsorb the first engaging unit 411 and the second engaging unit 421 (as shown in FIGS. 4(A) and Figure 8 shown) to perform subsequent engaging actions.

[0109] As shown in FIG. 3(B) (the first suction cup element 23 and the second suction cup element 24 are in a closed state), by driving the first driving unit 21, the first arm 211 and the second arm 212 can be turned over, so that the first suction cup element 23 and the second suction cup element 24 are changed from the open state (as shown in FIG. 3(A)) to the closed state, and the first joint unit 411 on the first suction cup element 23 and the second joint unit 412 on the second suction cup element 24 are used to join the first shrink film 11 and the second shrink film 12 (as shown in FIGS. 4(A), Figure 9 and Figure 15 shown).

[0110] In this embodiment, the first driving unit 21 is a jaw cylinder; in another embodiment, the first driving unit 21 is a motor, but the present invention is not limited thereto. In addition, in this embodiment, as shown in FIGS. 3(A) and 3(B), the first suction cup element 23 and the second suction cup element 24 can adsorb the first joint unit 411 and the second joint unit 421 thereon respectively by air flow, static electricity or other means.

[0111] Figures 4(A) to 4(C) A perspective view and a top view showing a joint unit supply mechanism according to an embodiment of the present invention.

[0112] As Figures 4(A) to 4(C) shown, the joint unit supply mechanism 4 is disposed adjacent to the suction cup mechanism 2 (as Figure 1 shown), and includes a first supply element 41, a second supply element 42 and a second driving unit 43. Among them, the first supply element 41 and the second supply element 42 are correspondingly arranged and connected to the second driving unit 43. Therefore, driving the second driving unit 43 can interlock the first supply element 41 and the second supply element 42, so that the first supply element 41 and the second supply element 42 can move toward or away from the first suction cup element 23 and the second suction cup element 24 respectively (as Figures 6 to 9 shown).

[0113] In addition, the first supply element 41 and the second supply element 42 are arranged adjacent to each other. In this embodiment, the first supply element 41 and the second supply element 42 are arranged in a vertically stacked manner; however, the present invention is not limited thereto. In addition, in this embodiment, the first joint unit 411 and the second joint unit 421 are tapes respectively, but the present invention is not limited thereto, as long as the shrink film can be joined, for example, it can be joined by means of colloid, welding or other film material joining methods.

[0114] Secondly, as shown in FIGS. 3(A), Figures 4(A) to 4(C)As shown, the first supply element 41 includes a first engaging unit 411, a first roller set 412, a first engaging platform 413, a first cutting element 414, and a first fixed shaft 415. The first engaging unit 411 is disposed on the first engaging platform 413 and fixed to the first fixed shaft 415. The first roller set 412 is disposed at the first engaging end 413a of the first engaging platform 413, corresponding to the first suction cup element 23, and provides the first engaging unit 411 disposed on the first roller set 412 to the first suction cup element 23. The adhesive surface of the first engaging unit 411 is adhered to the first roller set 412 to fix the first engaging unit 411. Since the contact area between the adhesive surface of the first engaging unit 411 and the first roller set 412 is not large, when the first engaging platform 413 moves closer to the first suction cup element 23, the first suction cup element 23 can easily adsorb the first engaging unit 411 (as shown in Figure 7 ); and the first cutting element 414 is disposed adjacent to the first roller set 412 to cut the first engaging unit 411.

[0115] Similarly, as shown in FIGS. 3(A), Figures 4(A) to 4(C) , the second supply element 42 includes a second engaging unit 421, a second roller set 422, a second engaging platform 423, a second cutting element 424, and a second fixed shaft 425. The second engaging unit 421 is disposed on the second engaging platform 423 and fixed to the second fixed shaft 425. The second roller set 422 is disposed at the second engaging end 423a of the second engaging platform 423, corresponding to the second suction cup element 24, and provides the second engaging unit 421 disposed on the second roller set 422 to the second suction cup element 24. The adhesive surface of the second engaging unit 421 is adhered to the second roller set 422 to fix the second engaging unit 421. Since the contact area between the adhesive surface of the second engaging unit 421 and the second roller set 422 is not large, when the second engaging platform 423 moves closer to the second suction cup element 24, the second suction cup element 24 can easily adsorb the second engaging unit 421; and the second cutting element 424 is disposed adjacent to the second roller set 422 to cut the second engaging unit 421.

[0116] In addition, as shown in Figures 4(A) to 4(C) and Figure 6 , the driving of the second driving unit 43 can move the connected first supply element 41 and second supply element 42 along the first conveying direction D1 and the fourth conveying direction D4 or the second conveying direction D2 and the third conveying direction D3, so that the engaging unit supply mechanism 4 can move toward or away from the suction cup mechanism 2 to provide the first engaging unit 411 or the second engaging unit 421 to the first suction cup element 23 or the second suction cup element 24 respectively (as shown in FIG. 3(A)).

[0117] In addition, as shown in FIGS. 3(A),Figures 4(A) to 4(C) As shown, the first supply element 41 is correspondingly arranged with the first suction cup element 23 and provides the first bonding unit 411 to the first suction cup element 23. Therefore, the first shrink film 11 and the second shrink film 12 can be bonded through the first bonding unit 411 on the first suction cup element 23 (as Figure 15 shown); Similarly, the second supply element 42 is correspondingly arranged with the second suction cup element 24 and provides the second bonding unit 421 to the second suction cup element 24. Therefore, the first shrink film 11 and the second shrink film 12 can also be bonded through the second film bonding unit 421 on the second suction cup element 24 (as Figure 15 shown).

[0119] As Figures 5(A) to 5(C) shown, the feeding mechanism 3 includes a feeding table 31, two belt fixing elements 32, a belt 33, a cutting unit 34, a first roller 35, a turning roller 36, a through hole 37, a second roller 38, a belt 381, a roller 382, and a motor 39. Among them, the feeding table 31 has a second film bonding end 31a, and the second film bonding end 31a is correspondingly arranged with the first film bonding end 10a of one of the plurality of shrink film channels 10. Therefore, the feeding mechanism 3 can receive the first shrink film 11, the second shrink film 12, and the shrink films 13, 14, 15, 16 from one of the plurality of shrink film channels 10 (as Figure 1 shown). The two belt fixing elements 32 are arranged at the second film bonding end 31a of the feeding table 31 and are arranged in the through hole 37. In addition, there is a distance d between the two belt fixing elements 32. Therefore, the size of the distance d can be adjusted by adjusting the positions of the two belt fixing elements 32 in the through hole 37 so that the size of the distance d corresponds to the widths of the first shrink film 11, the second shrink film 12, and the shrink films 13, 14, 15, 16 (as Figure 1 shown). In this embodiment, the distance d is slightly larger than the width of the shrink film, but the present invention is not limited thereto.

[0120] In addition, the belt 33 is assembled on the two belt fixing elements 32, but the belt 33 does not pass between the two belt fixing elements 32, and the space between the two belt fixing elements 32 is reserved to facilitate the conveyance of the first shrink film 11, the second shrink film 12, and the shrink films 13, 14, 15, 16 (as Figure 1 shown). In this embodiment, the form of the belt 33 is a flat belt, but the present invention is not limited thereto. The cutting unit 34 is arranged corresponding to the distance d between the two belt fixing elements 32 so as to cut one of the first shrink film 11, the second shrink film 12, and the shrink films 13, 14, 15, 16 from the plurality of shrink film channels 10 (as Figure 1As shown. In this embodiment, the cutting unit 34 is a blade, but the present invention is not limited thereto. For example, it can be scissors, a saw blade, or any element suitable for cutting the shrink film.

[0121] In addition, the first roller 35 and the second roller 38 are arranged at the second film-receiving end 31a of the feeding table 31, and the first shrink film 11 can pass between the first roller 35 and the second roller 38. The second roller 38 is connected to the motor 39 by a belt 381 through the roller 382 assembled therewith, so that the second roller 38 serves as the driving wheel and the first roller 35 serves as the driven wheel to drive the first shrink film 11 to move forward, and the first shrink film 11 is stably supplied through the first roller 35 and the second roller 38. The rotation directions of the first roller 35 and the second roller 38 can be determined by the first conveying direction D1 or the fourth conveying direction D4. The turning roller 36 is arranged on the feeding table 31 so that the first shrink film 11 can be conveyed from the first conveying direction D1 to the second conveying direction D2, and the first conveying direction D1 is different from the second conveying direction D2. The conveying direction of the first shrink film 11 is changed by the arrangement of the turning roller 36. In addition, the turning roller 36 is not limited to changing the conveying direction of the first shrink film 11. As long as one of the first shrink film 11, the second shrink film 12, and the shrink films 13, 14, 15, 16 (as Figure 1 shown) is supplied to the turning roller 36, its conveying direction can also be changed. Secondly, the first conveying direction D1 can be the direction from the first film-receiving end 10a to the second film-receiving end 31a of one of the plurality of shrink film channels 10 (as Figure 1 shown). In this embodiment, the first conveying direction D1 is orthogonal to the second conveying direction D2, but the present invention is not limited thereto.

[0122] Figures 6 to 9 The top view of the operation of the joint unit supply mechanism and the suction cup mechanism showing an embodiment of the present invention.

[0123] As shown in FIGS. 3(A), 4(A) and Figure 6 shown, at this time, the joint unit supply mechanism 4 and the suction cup mechanism 2 are in the standby state. The adhesive surfaces of the first joint unit 411 and the second joint unit 421 of the joint unit supply mechanism 4 are respectively arranged on the first roller group 412 and the second roller group 422, and the first roller group 412 and the second roller group 422 are respectively arranged corresponding to the first suction cup element 23 and the second suction cup element 24; in addition, the first suction cup element 23 and the second suction cup element 24 of the suction cup mechanism 2 are in the open state (the included angle between the two is substantially 180 degrees) to be ready to adsorb the first joint unit 411 and the second joint unit 421 at any time.

[0124] As shown in FIGS. 3(A), 4(A) and Figure 7As shown, by the second driving unit 43 of the driving engagement unit supply mechanism 4, the first supply element 41 and the second supply element 42 connected thereto move along the first conveying direction D1 toward the suction cup mechanism 2. Next, the first suction cup element 23 and the second suction cup element 24 respectively adsorb the opposite sides of the adhesive surfaces of the first engagement unit 411 and the second engagement unit 421 through the suction air flow. In this embodiment, the adsorption is performed by the suction air flow, but the present invention is not limited thereto; in other embodiments, the adsorption can also be performed by static electricity or other means.

[0125] As shown in FIGS. 3(A), 4(A) and Figure 8 As shown, since one ends of the first engagement unit 411 and the second engagement unit 421 have been adsorbed on the first suction cup element 23 and the second suction cup element 24, by driving the second driving unit 43, the first supply element 41 and the second supply element 42 move along the second conveying direction D2, and at the same time, the first engagement unit 411 and the second engagement unit 421 are pulled apart, so that the surfaces of the first suction cup element 23 and the second suction cup element 24 are respectively covered by the first engagement unit 411 and the second engagement unit 421. In this embodiment, the surfaces of the first suction cup element 23 and the second suction cup element 24 are completely covered by the first engagement unit 411 and the second engagement unit 421, but the present invention is not limited thereto, and the proportion of the surfaces of the first suction cup element 23 and the second suction cup element 24 covered by the first engagement unit 411 and the second engagement unit 421 can also be adjusted according to requirements.

[0126] As shown in FIGS. 3(A), 4(A) and Figure 9 As shown, since the first engagement unit 411 and the second engagement unit 421 have been adsorbed on the surfaces of the first suction cup element 23 and the second suction cup element 24, cutting is performed by the first cutting element 414 and the second cutting element 424 respectively provided on the first supply element 41 and the second supply element 42, and the first engagement unit 411 and the second engagement unit 421 are cut into a predetermined length and respectively adsorbed on the first suction cup element 23 and the second suction cup element 24 for subsequent film joining. In addition, after the first cutting element 414 and the second cutting element 424 finish cutting, the second driving unit 43 will be driven to move the first supply element 41 and the second supply element 42 away from the suction cup mechanism 2 along the third conveying direction D3 and the fourth conveying direction D4, and return to the initial position (as Figure 6 As shown). In this embodiment, the engagement unit supply mechanism 4 returns to the initial position, but the present invention is not limited thereto, as long as the position of the engagement unit supply mechanism 4 does not affect the subsequent operation of the suction cup mechanism 2.

[0127] Figures 10 to 15 It is a three-dimensional schematic diagram of the operation of the automatic film joining device according to an embodiment of the present invention.

[0128] As shown in Figure 10 , at this time, the first shrink film 11 is supplied to the feeding mechanism 3. The first shrink film 11 is conveyed between two belt fixing elements 32, and the second roller 38 is rotated to convey the first shrink film 11 in the first conveying direction D1 (as shown in Fig. 5(C)). Then, the first shrink film 11 is conveyed from the first conveying direction D1 to the fourth conveying direction D4 by the turning roller 36. At the same time, the first bonding unit 411 and the second bonding unit 421 of the bonding unit supply mechanism 4 have been respectively arranged on the first suction cup element 23 and the second suction cup element 24 (as shown in Fig. 3(A) and Fig. 4(A)), waiting to be used for film bonding. In addition, the belt 33 can also pass through the first film layer and the second film layer of at least one of the cut second shrink film 12 and the shrink films 13, 14, 15, 16 (as shown in Figure 1 and Figure 11 ), to support the second shrink film 12 and the shrink films 13, 14, 15, 16 (as shown in Figure 1 ).

[0129] As shown in Figure 11 , when the first shrink film 11 remains a predetermined length, it is ready to bond the first shrink film 11 with the second shrink film 12. Therefore, the cutting unit 34 of the feeding mechanism 3 first cuts the first shrink film 11 (as shown in Fig. 5(A)) to form an end 111 of the first shrink film 11. At this time, the feeding mechanism 3 enters the state of preparing to bond the film. The motor 39 drives the second roller 38 through the belt 381 (as shown in Fig. 5(C)) to convey the first shrink film 11 forward by a specific distance, so that the end 111 of the first shrink film 11 is moved out of the shrink film channel 10 between the two belt fixing elements 32, which is conducive to subsequently bonding the end 111 of the first shrink film 11 with the second shrink film 12. In this embodiment, a detection unit (not shown in the figure) can be set to detect the remaining lengths of the first shrink film 11, the second shrink film 12 and the shrink films 13, 14, 15, 16 (as shown in Figure 1 ). There is no special limitation on the type of the detection unit. For example, it can be an optical detection unit or other detection units.

[0130] As shown in Figure 11 and Figure 12As shown, by driving a third driving element (not shown in the figure), the feeding mechanism 3 disposed between the first rail 51 and the third rail 53 is moved along the third conveying direction D3. Since the belt 33 is disposed between the first film layer 12a and the second film layer 12b of the second shrink film 12, when the feeding mechanism 3 moves along the third conveying direction D3, the end 111 of the first shrink film 11 will move into the space between the first film layer 12a and the second film layer 12b of the second shrink film 12, that is, the first film layer 12a of the second shrink film 12 is located above the first shrink film 11, and the second film layer 12b of the second shrink film 12 is located below the first shrink film 11.

[0131] As shown in FIGS. 3(A), 4(A) and Figure 13 As shown, by driving a fourth driving element (not shown in the figure), the sucking mechanism 2 is moved along the third conveying direction D3, and the first sucking element 23 and the second sucking element 24 of the sucking disc mechanism 2 are correspondingly disposed with the first film layer 12a and the second film layer 12b of the second shrink film 12 (as Figure 11 shown), so as to prepare for film joining by using the first joining unit 411 and the second joining unit 421.

[0132] As shown in FIGS. 3(A), 4(A), Figure 11 and Figure 14 As shown, by driving the first driving element 21, the first sucking element 23 and the second sucking element 24 of the sucking disc mechanism 2 are changed from the open state to the closed state (that is, the included angle between the two substantially changes from 180 degrees to 0 degrees, but the present invention is not limited thereto), and further, the first joining unit 411 previously disposed on the first sucking element 23 is attached to the first film layer 12a of the second shrink film 12 and the first shrink film 11, and at the same time, the second joining unit 421 previously disposed on the second sucking element 24 is attached to the second film layer 12b of the second shrink film 12 and the first shrink film 11, thereby successfully joining the first shrink film 11 and the second shrink film 12 and completing the film joining operation.

[0133] As shown in FIGS. 3(A), 4(A) and Figure 15 As shown, after the first shrink film 11 and the second shrink film 12 are joined, the second roller 38 of the feeding mechanism 3 resumes its rotation speed (as shown in FIG. 5(C)), and starts to feed with the second shrink film 12 instead. Secondly, the sucking disc mechanism 2 also returns to its initial position along the second conveying direction D2 by means of a fourth driving element (not shown in the figure), and the joining unit supply mechanism 4 provides the first joining unit 411 and the second joining unit 421 for the first sucking element 23 and the second sucking element 24 again. As for when the second shrink film 12 and the shrink films 13, 14, 15, 16 are about to be used up (as Figure 1 shown), its joining operation is similar to the joining operation when the first shrink film 11 is used up, and will not be described in detail.
