Description

[Technical field]

[0001] The present invention relates to a tape processing apparatus for processing an excess portion of a tape extending beyond a film. [Background technology]

[0002] There is an apparatus that performs processes such as coating and heat treatment on a web unwound from an original roll, and then winds the web to form a product roll (see, for example, Patent Document 1). In such an apparatus, a tape application device applies tape to connect the web on the winding side to a newly set web on the unwinding side. In Patent Document 1, multiple tapes are applied along the running direction of the web, and the tapes are arranged between one side of the web on the winding side and one side of the newly set web on the unwinding side.

[0003] [Patent Document 1] JP 2013-256347 A Summary of the Invention [Problem to be solved by the invention]

[0004] When webs are joined together with tape, it may become necessary to deal with excess tape that extends beyond the edges of the web.

[0005] The present invention has been proposed in consideration of the above-mentioned problems associated with the conventional technology, and aims to provide a tape processing device that can appropriately process excess tape using a simple mechanism. [Means for solving the problem]

[0006] In order to overcome the above problems and achieve the intended object, the tape processing device according to the invention of claim 1 of the present application comprises: a standing member capable of pushing out an excess portion of a tape attached to a front surface of a film, the excess portion extending beyond an edge of the film, toward a rear surface side of the film; The gist of the present invention is that it is equipped with a folding member that can fold back the excess portion pressed by the standing member onto the back surface of the film. According to the invention of claim 1, the standing member that pushes out the excess part of the tape and the folding member that folds back the excess part are separate, so the operation of each of the standing member and the folding member can be simplified, and the mechanism as a whole can be simplified. Also, because the folding back of the excess part is separated into the standing member and the folding member, it is possible to fold back the excess part without difficulty, and the folding back process of the excess part can be performed appropriately.

[0007] The invention of claim 2 is characterized in that the tip end of the standing member and the tip end of the folding member have a concave and convex shape that can interlock with each other when the standing member presses the excess portion and the folding member folds back the excess portion. According to the invention of claim 2, even if the standing member and the folding member are operated at the same time, the uneven shapes of their leading ends mesh with each other, so that interference between their leading ends can be prevented. Therefore, while the surplus part of the tape is kept pressed by the standing member, the folding member can be operated to receive the standing surplus part from the standing member and folded back onto the back surface of the film. This allows the surplus part of the tape to be folded back more neatly, improving the quality of the connection between the films.

[0008] The invention according to claim 3 is characterized in that a surface supporting member for supporting the surface of the film is provided. According to the invention of claim 3, when the excess portion is folded back with the folding member, the film is supported by the surface support member, thereby suppressing deformation such as bending of the film and allowing the excess portion to be properly overlapped on the back surface of the film.

[0009] The invention according to claim 4 is characterized in that a back surface supporting member for supporting the back surface of the film is provided. According to the invention of claim 4, when the excess portion is pushed by the standing member, the film is supported by the back support member, so that deformation of the film, such as bending, can be suppressed and the excess portion can be properly pushed toward the back side of the film.

[0010] In the invention according to claim 5, the standing member is provided to be movable forward and backward in the front-back direction of the film between a receiving position on the front side of the film and an extruding position protruding from the back side of the film, The folding member is provided so as to be rotatable between a retracted position where it is displaced from the back surface of the film and a folded position where it overlaps with the back surface. According to the invention of claim 5, the excess portion of the tape can be folded back to the back surface of the film by simple operation of the standing member and the folding member. Also, the mechanism for operating the standing member and the folding member can be simplified. Effect of the Invention

[0011] According to the tape processing device of the present invention, the excess portion of the tape can be appropriately processed with a simple mechanism. [Brief description of the drawings]

[0013] Next, a tape processing apparatus according to a preferred embodiment of the present invention will be described below with reference to the accompanying drawings. EXAMPLES

[0014] 1, the tape processing device 30 according to the embodiment is provided in a rewinder 10 that winds up the film F, unwound from a raw roll 14 set in an unwinding section 12, in a winding section 16 to form a product roll 18. The rewinder 10 in the embodiment has multiple (two) winding sections 16, and is capable of winding up the film F at multiple locations (two locations).

[0015] As shown in FIG. 1, the rewinder 10 includes a tape application device 20 that applies tape T and a film cutting device 22 that cuts the film F. The tape application device 20 and the film cutting device 22 are arranged corresponding to the running path of the film F between the unwinding section 12 and the winding section 16. In the embodiment, the tape application device 20 and the film cutting device 22 are provided corresponding to each of the running paths of the film F toward the multiple winding sections 16. In the embodiment, the tape T is applied to the film F in a direction perpendicular to the running direction of the film F, and connects the end of the film F on the winding section 16 side to the start of the film F unwound from the original roll 14 set in the unwinding section 12. The tape T is applied so that excess portions Ta extend from both edges of the film F. The reference numeral 24 denotes a fixed suction plate that can suction and hold the end of the film F on the winding section 16 side. Further, reference numeral 26 denotes a movable suction plate capable of suctioning and holding the starting end of film F on the unwinding section 12 side, and is used by switching the travel path for holding.

[0016] As shown in Fig. 1, the tape processing device 30 is disposed downstream in the running direction of the film F in the tape application device 20 and upstream in the running direction of the film F in the winding section 16. In this embodiment, a tape processing device 30 is provided corresponding to each of the running paths of the film F toward the multiple winding sections 16. Here, the surface of the film F to which the tape T is applied by the tape application device 20 is referred to as the front surface, and the opposite surface is referred to as the back surface for convenience. The tape processing device 30 folds back and applies the excess portion Ta of the tape T applied to the front surface of the film F by the tape application device 20 to the back surface of the film F (see Figs. 7 and 8).

[0017] 2, the tape processing device 30 includes a standing member 32 capable of pushing out the excess portion Ta of the tape T protruding from the edge of the film F toward the back surface of the film F. The tape processing device 30 also includes a folding member 34 capable of folding back the excess portion Ta of the tape T pushed by the standing member 32 onto the back surface of the film F. The folding member 34 in the embodiment is capable of pressing the folded back excess portion Ta against the back surface of the film F to attach it thereto. The tape processing device 30 also includes a front surface support member 36 that supports the front surface of the film F, and a back surface support member 38 that supports the back surface of the film F.

[0018] As shown in Fig. 2(b), Fig. 3 and Fig. 6, two standing members 32, 32 are provided on either side of a support surface 36a that supports the film F on the front support member 36. The standing member 32 is provided so as to be movable forward and backward in the front-rear direction of the film F between a receiving position (see Figs. 7(a) and (b), Figs. 8(a) and (b)) on the front side of the film F and an extrusion position (see Figs. 7(c) and (d), Figs. 8(c) and (d)) that protrudes on the back side of the film F. At the receiving position, the standing member 32 retreats so as not to protrude from the support surface 36a, so as not to interfere with the running of the film F or the arrival of the film F with the tape T between the front support member 36 and the back support member 38. When the standing member 32 moves from the receiving position to the extrusion position, the tip portion 32a protrudes from the support surface 36a. The standing member 32 is moved linearly back and forth by an actuator (not shown), such as a fluid pressure cylinder such as an air pressure cylinder or a motor. In this embodiment, the standing member 32 is assembled to a surface support member 36.

[0019] As shown in Fig. 2(b), Fig. 3 and Fig. 6, two folding members 34, 34 are provided on either side of the support surface 36a of the front surface support member 36. The folding member 34 is provided rotatably between a retreated position (see Figs. 7(a)-(c) and Figs. 8(a)-(c)) where it is removed from the back surface of the film F and a folded position (see Figs. 7(d) and 8(d)) where it is overlapped with the back surface of the film F. At the retreated position, the folding member 34 is retreated so as to be located outside the standing member 32 and removed from the running path of the film F, so as not to interfere with the running of the film F or the arrival of the film F with the tape T between the front surface support member 36 and the back surface support member 38. When the folding member 34 moves from the retreated position to the folded position, the tip portion 34a overlaps the support surface 36a. The folding member 34 is advanced and retreated by an actuator (not shown), such as a fluid pressure cylinder such as an air pressure cylinder or a motor. In the embodiment, the folding member 34 is journalled to a surface support member 36 .

[0020] As shown in Figs. 7(c) and (d), the tip 32a of the standing member 32 that presses the excess portion Ta and the tip 34a of the folded-back member 34 that folds back the excess portion Ta have an uneven shape that can mesh with each other when the standing member 32 presses the excess portion Ta and the folded-back member 34 folds back the excess portion Ta. At the extrusion position, the standing member 32 is configured so that the convex part of the uneven tip 32a protrudes from the support surface 36a (see Figs. 8(c) and (d)). The folded-back member 34 is pivotally supported by the surface support member 36 at a position outside the tip 32a of the standing member 32, and at the retracted position, the tip 34a of the folded-back member 34 is disposed outside the tip 32a of the standing member 32 (see Figs. 8(a) to (c)). At the folded-back position, the folded-back member 34 is disposed so that the tip 34a overlaps the standing member 32 (see Fig. 8(d)). At this time, the convex portion of the tip 34a of the folding member 34 enters the concave portion of the tip 32a of the standing member 32, and the convex portion of the tip 32a of the standing member 32 enters the concave portion of the tip 34a of the folding member 34. In the embodiment, the convex portion of the tip 34a of the folding member 34 in the folded position extends inward beyond the standing member 32 and is disposed so as to overlap the supporting surface 36a (the back surface of the film F supported by the supporting surface 36a).

[0021] As shown in Figures 2 and 5, the base of the folded member 34 opposite the tip 34a is provided with a relief portion 34b capable of receiving the base 32b of the standing member 32 opposite the tip 32a. The relief portion 34b is formed in a concave shape recessed toward the tip 34a side, and is capable of receiving the base 32b of the standing member 32 in the extrusion position. In this way, by providing the relief portion 34b, it is possible to prevent interference with the folded member 34 and increase the stroke of the standing member 32. In addition, since the folded member 34 rotates and moves, even if the base 32b of the standing member 32 is received in the relief portion 34b, the operation of the folded member 34 is not affected.

[0022] Either or both of the front support member 36 and the back support member 38 are configured to be movable toward and away from the traveling path of the film F, and the front support member 36 and the back support member 38 are configured to be openable and closable relative to one another. By opening the space between the front support member 36 and the back support member 38, the traveling of the film F and the arrival of the film F with the tape T between the front support member 36 and the back support member 38 are not impeded (see FIG. 8(a)). When the excess portion Ta of the tape T is folded, attached, or otherwise processed, the space between the front support member 36 and the back support member 38 is closed to support the film F (see FIGS. 8(b) to (d)).

[0023] 6 and 8, the back surface support member 38 is adapted to press the widthwise center of the film F along the running direction of the film F, and in this embodiment, presses a wider range in the running direction than the standing members 32 and the folding back members 34. The back surface support member 38 is adapted to press not only the position where the tape T is attached, but also the end of the film F on the winding section 16 side and the start end of the film F unwound from the original roll 14 set in the unwinding section 12 (see FIG. 2).

[0024] Next, the processing of the excess portion Ta of the tape T using the tape processing device 30 will be described. The end portion of the film F is cut by the film cutting device 22 in a direction perpendicular to the running direction of the film F, and the end of the film F is trimmed. The tape application device 20 applies the tape T so as to straddle the end and the beginning of the film F that are butted against each other, and cuts the tape T. The film F with the excess portion Ta of the tape T protruding from its edge is run, and the application portion of the film F to which the tape T is applied is positioned between the front support member 36 and the back support member 38 that are in an open state in the tape processing device 30 (see FIG. 7(b) and FIG. 8(a)). At this time, the standing member 32 is in the receiving position, and the folding member 34 is in the retracted position.

[0025] The front surface supporting member 36 and the back surface supporting member 38 are closed, and the front surface of the film F is supported by the front surface supporting member 36, while the back surface of the film F is supported by the back surface supporting member 38 (see FIG. 8(b)). Next, the standing member 32 is moved from the receiving position to the pushing position, so that the standing member 32 protruding along the edge of the film F pushes the excess portion Ta of the tape T protruding from the edge of the film F toward the back surface of the film F, thereby standing the excess portion Ta along the edge of the film F (see FIGS. 7(c) and 8(c)). Then, the tip portion 32a of the standing member 32 in the pushing position is positioned outside the standing excess portion Ta, thereby maintaining the standing posture of the excess portion Ta.

[0026] Next, by moving the folding member 34 from the retreated position to the folding position, the excess portion Ta that has been made to stand by the standing member 32 is folded back onto the back surface of the film F (see FIG. 7(d) and FIG. 8(d)). At this time, the folding member 34 passes through the recess 38a provided in the back surface support member 38, and the excess portion Ta folded back by the folding member 34 is overlapped onto the back surface of the film F. Then, the folding member 34 in the folding position presses the excess portion Ta against the back surface of the film F, and the excess portion Ta is attached to the back surface of the film F. In this way, the excess portion Ta of the tape T is folded back onto the back surface of the film F, and the processing of the excess portion Ta is completed. In the embodiment, the standing member 32 is left disposed at the extrusion position when the excess portion Ta is folded back by the folding member 34.

[0027] The folding member 34 is returned from the folding position to the retracted position, and the standing member 32 is returned from the pushing position to the receiving position. Then, the front support member 36 and the back support member 38 are opened, thereby allowing the film F connected with the tape T to run.

[0028] When the excess portion Ta of the tape T attached to the front surface of the film F that protrudes from the edge of the film F is folded back onto the back surface of the film F, the excess portion Ta is lifted from the front surface side of the film F to the back surface side, and then the excess portion Ta is overlapped onto the back surface of the film F. If such folding back of the excess portion Ta is performed using one member, the member will have to move along a complex trajectory, making the mechanism complicated. Since the tape processing device 30 has a standing member 32 that stands the excess portion Ta of the tape T and a folding back member 34 that folds back the excess portion Ta, which are separate, the operation of the standing member 32 and the folding back member 34 can be simplified, and the mechanism as a whole can be simplified. Furthermore, since the tape processing device 30 has the folding back of the excess portion Ta divided between the standing member 32 and the folding back member 34, it is possible to fold back the excess portion Ta without difficulty, and the folding back process of the excess portion Ta can be performed appropriately.

[0029] In the tape processing device 30, the tip 32a of the standing member 32 and the tip 34a of the folding member 34 have an uneven shape that can mesh with each other when the standing member 32 presses the excess portion Ta and the folding member 34 folds the excess portion Ta. That is, even if the folding member 34 is operated while the standing member 32 is operated, the uneven shapes of the tip portions 32a, 34a mesh with each other, so that interference between the tip portions 32a, 34a can be prevented. Therefore, while keeping the excess portion Ta of the tape T in an upright state by the standing member 32, the folding member 34 can be operated to receive the upright excess portion Ta from the standing member 32 and fold it back onto the back surface of the film F. This allows the excess portion Ta of the tape T to be folded back more neatly, improving the quality of the connection portion between the films F. In the embodiment, with the standing member 32 positioned on the side of the excess portion Ta standing upright from the edge of the film F, the excess portion Ta is folded back by the folding member 34, so that the excess portion Ta can be folded neatly along the edge of the film F.

[0030] The tape processing device 30 includes a surface support member 36 that supports the surface of the film F. As a result, when the surplus portion Ta is folded back by the folding back member 34, the film F is supported by the surface support member 36, so that the surplus portion Ta can be appropriately overlapped on the back surface of the film F while suppressing deformation such as bending of the film F.

[0031] The tape processing device 30 includes a back surface support member 38 that supports the back surface of the film F. As a result, when the standing member 32 presses the excess portion Ta, the film F is supported by the back surface support member 38, so that deformation such as bending of the film F is suppressed, and the excess portion Ta can be appropriately pushed out toward the back surface side of the film F.

[0032] The tape processing device 30 is configured to move the standing member 32 back and forth in the front-back direction of the film F, and to rotate the folding-back member 34. In this way, by simple operations of the standing member 32 and the folding-back member 34, the excess portion Ta of the tape T can be folded back to the back side of the film F. Also, the mechanism for operating the standing member 32 and the folding-back member 34 can be simplified.

[0033] (Example of change) The present invention is not limited to the above-mentioned items, and may be, for example, as follows: It should be noted that the present invention is not limited to the specific descriptions of the examples and the following modified examples. (1) In the embodiment, a configuration has been described in which the standing member and the turn-back member can be independently operated by separate actuators, but this is not limiting, and a linking means such as gears or links may be provided between the standing member and the turn-back member, and the standing member and the turn-back member may be linked and operated by one actuator. Also, two (multiple) standing members linked by linking means such as gears or links may be operated by one actuator, and similarly, two (multiple) turn-back members linked by linking means such as gears or links may be operated by one actuator. (2) Either or both of the front and back support members may be omitted. For example, in the case of a film that is relatively hard to bend, such as a metal foil, the film does not slip away when the excess portion is folded back or attached, so that it is possible to omit the support members. (3) In the embodiment, a rewinder that rewinds a film is illustrated, but this is not limited to this. The tape processing device disclosed herein can be applied to devices that wind a film, such as a slitter that cuts the film to a specified width or other winding devices (winders). (4) Examples of films include films that can be rolled up, such as synthetic resins, metals, and paper. (5) The tape may be attached to the film by either a pressure sensitive adhesive or an adhesive. The tape may be attached to the film by contact with the film or by the passage of time or by treatment such as heating. (6) In the embodiment, the tape is applied in a direction perpendicular to the running direction of the film. However, when the tape is applied in a direction parallel to the running direction of the film or at an angle to the running direction, the excess portion of the tape extending beyond the edge of the film may be folded back by the tape processing device. (7) The tape processing device of the present disclosure is not limited to a configuration in which the tape protrudes from both edges of the film as in the embodiment, but may also be applicable to a configuration in which the tape protrudes from one edge of the film. In this case, the configuration may be such that only the pair of standing members and folding members on one side are operated, or the pair of standing members and folding members on the side where the excess portion of the tape does not protrude may be omitted. (8) In the embodiment, an example was given in which a tape processing device is provided on a running path along which a film whose front and back surfaces extend horizontally runs horizontally. However, this is not limited to this. For example, the tape processing device of the present disclosure may be provided on a running path along which a film whose front and back surfaces extend vertically runs horizontally, or on a running path along which a film runs vertically (up and down) or diagonally. (9) As in the embodiment, the tape application device is not limited to having a means for cutting the tape, and the means for cutting the tape may be provided separately from the tape application device.
