  There is a film transport device that transports various films such as a multilayer film. Such a film transport device includes, for example, a device that performs various processes such as sticking of another film to a film being transported and peeling of a part of a layer from the film being transported. Some film conveying devices shear a part of the film being conveyed.

  In the film transport apparatus as described above, it is necessary to apply a certain tension to the film being transported to eliminate deformation such as slack and meandering of the film, and to ensure a stable transport state of the film.

[Operation during film transport]
Below, the operation | movement of the entrance side grip feeder 22 and the exit side grip feeder 23 at the time of conveyance of the film 100 is demonstrated (refer FIG. 6 thru | or FIG. 12).

  In the following, description will be made with reference to the operation diagrams of FIGS. 6 to 11 and the time chart diagram of FIG. 12, and in order to facilitate understanding, the film 100 is slack before the operation starts. It shall be. In addition, each operation time of T1 to T9 in FIG. 12 shown below is controlled by a timer and a control unit (not shown) so as to be performed every predetermined time in advance.

  First, initial states of the first fixed clamper 25, the first moving clamper 26, the second fixed clamper 29, and the second moving clamper 30 will be described (see FIG. 6).

  In the initial state, the first fixed clamper 25 is set in a holding state in which the movable portion 25a is moved downward to hold the film 100, and the first moving clamper 26 is in a standby position which is a left moving end and is movable. The second fixed clamper 29 is set in a clamping state in which the movable part 29a is moved downward and the film 100 is clamped. The second moving clamper 30 is in a standby position, which is the left moving end, and is set in a non-nipping state in which the movable part 30a is moved upward and the nipping with respect to the film 100 is released. Therefore, in the initial state, the film 100 is sandwiched between the first fixed clamper 25 and the second fixed clamper 29.

  In addition, about the operation | movement at the time of conveyance of the film 100 shown below, position determination operation | movement, tension | tensile_strength control operation, and synchronous operation are performed as an operation | movement (operation state) of each part.

  The positioning operation is an operation in which each motor for moving the moving clamper is operated in accordance with a command from a control unit (not shown), and the moving clamper is moved or stopped by a set distance.

  The tension control operation is an operation in which each motor that moves the moving clamper is operated according to the torque value (tension) set in the control unit and the operation time, and the moving clamper moves for a set time with the set torque. . Even before the set time elapses, when the tension of the film 100 reaches the set value and the moving force and the tension are balanced, the moving clamper is stopped while the tension is maintained.

  The synchronous operation is an operation in which the other motor is driven at the same movement amount and movement speed as the one motor in synchronization with the driving state of the one motor in which the main drive is performed. The moving clamper moved by the two motors is moved in a state where the distance between the two is kept constant.

  The operation is started in the above-described initial state. At this time, in the film transport apparatus 1, the entrance-side grip feeder 22 and the exit-side grip feeder 23 are both positioned. When the operation is started, the movable portion 30a is moved downward, and the second moving clamper 30 is set in the clamping state (see T1 in FIG. 12).

  Next, the movable portion 29a is moved upward so that the second fixed clamper 29 is set in a non-nipping state, and the film 100 is held in a surface contact state by the first fixed clamper 25 and the second moving clamper 30. (See T2 in FIGS. 7 and 12).

  Subsequently, the exit-side grip feeder 23 is switched from the positioning operation to the tension control operation, and the second moving clamper 30 is moved to the right from the standby position for a predetermined time (see T3 in FIGS. 8 and 12). At this time, the second moving clamper 30 is moved to the right with a smaller amount of force (set tensile torque) than when the film 100 described later is conveyed, and tension is applied to the film 100 to eliminate loosening and meandering.

  Since the second moving clamper 30 is moved with a small amount of force in this way, the tension of the film 100 and the movement of the second moving clamper 30 are applied when a certain tension is applied to the film 100 even within a predetermined time. The movement of the second moving clamper 30 is stopped in balance with the force. Therefore, excessive tension is not applied to the film 100 from the second moving clamper 30, and the film 100 is not cracked or broken.

  In the above example, the film 100 is sandwiched between the first fixed clamper 25 and the second moving clamper 30 at T2, but the first moving clamper 26 and the second moving clamper 30 at T2. It is also possible that the film 100 is sandwiched and the first moving clamper 26 is not moved at T3 and the second moving clamper 30 is moved to the right from the standby position to apply tension to the film 100. .

  Further, at T2, the film 100 is sandwiched between the first moving clamper 26 and the second moving clamper 30, and at T3, the second moving clamper 30 is not moved and the first moving clamper 26 is moved to the left to move the film. It is also possible to apply tension to 100. In this case, the first moving clamper 26 needs to be positioned to the right of the standby position in the initial state.

  Further, the film 100 is sandwiched between the first moving clamper 26 and the second moving clamper 30 at T2, and the first moving clamper 26 and the second moving clamper 30 are moved together at T3 to apply tension to the film 100. It is also possible to do so.

  In this case, there are three embodiments: a first embodiment, a second embodiment, and a third embodiment.

  In the first embodiment, both the first moving clamper 26 and the second moving clamper 30 are moved to the right, and the moving amount of the second moving clamper 30 is greater than the moving amount of the first moving clamper 26. This is an embodiment to be enlarged.

  In the second embodiment, both the first moving clamper 26 and the second moving clamper 30 are moved leftward so that the moving amount of the first moving clamper 26 is larger than the moving amount of the second moving clamper 30. Embodiment. In the second embodiment, the first moving clamper 26 and the second moving clamper 30 need to be positioned to the right of the standby position in the initial state.

  In the third embodiment, the first moving clamper 26 is moved to the left and the second moving clamper 30 is moved to the right. In the third embodiment, the difference between the movement amount of the first movement clamper 26 and the movement amount of the second movement clamper 30 is arbitrary, and the movement amount of the first movement clamper 26 and the second movement clamper 30. The movement amount of the first movement clamper 26 and the movement amount of the second movement clamper 30 may be the same. In the third embodiment, the first moving clamper 26 needs to be positioned to the right of the standby position in the initial state.

  Next, the inlet-side grip feeder 22 is positioned and the outlet-side grip feeder 23 is switched from the tension control operation to the synchronous operation. The movable portion 26a is moved downward and the first moving clamper 26 is set in the clamping state. (See T4 in FIG. 12).

  Subsequently, the movable portion 25a is moved upward so that the first fixed clamper 25 is set in a non-clamping state, and the film 100 is held in a surface contact state by the first moving clamper 26 and the second moving clamper 30. (See T5 in FIGS. 9 and 12).

  Next, the first moving clamper 26 and the second moving clamper 30 sandwiching the film 100 are moved rightward to the transport position in synchronization with each other, and the film 100 is transported in a state where slack is eliminated. (See T6 in FIGS. 10 and 12).

  Subsequently, the movable portion 25a is moved downward to set the first fixed clamper 25 in the sandwiched state, and the movable portion 29a is moved downward to set the second fixed clamper 29 in the sandwiched state (see FIG. 12 T7).

  Next, the movable portion 26a is moved upward to set the first moving clamper 26 in a non-clamping state, and the movable portion 30a is moved upward to set the second moving clamper 30 in a non-clamping state. The film 100 is clamped in a surface contact state by the first fixed clamper 25 and the second fixed clamper 29 (see T8 in FIGS. 11 and 12).

  Subsequently, the outlet side grip feeder 23 is switched from the synchronous operation to the positioning operation, and the first moving clamper 26 and the second moving clamper 30 are moved leftward from the transport position to the standby position, and the first fixed clamper is moved. 25, the first moving clamper 26, the second fixed clamper 29, and the second moving clamper 30 are returned to the initial state, and the operation of one cycle is completed (see T9 in FIGS. 6 and 12).

  When the first fixed clamper 25, the first moving clamper 26, the second fixed clamper 29, and the second moving clamper 30 return to the initial state, the above-described operations from T1 to T9 are repeated, and the slack is eliminated. In this state, the film 100 is intermittently conveyed by a plurality of cycles of operation.

  As described above, in the film transport apparatus 1, the first moving clamper 26 and the second moving clamper 30 are moved, and the film 100 to which tension is applied is transported. The fixed clamper 25 and the second fixed clamper 29 are set in a clamping state (see FIG. 11).

  Therefore, since the film 100 is sandwiched between the first fixed clamper 25 and the second fixed clamper 29 in a state where the film 100 from which the slack has been eliminated is transported, the film 100 when the film 100 is transported next time. Sag and meandering can be suppressed.

  In the above, the example in which the second moving clamper 30 is moved to the right from the standby position for a predetermined time at T3 to eliminate the slackness of the film 100, but instead, at the end of T2 is shown. The first moving clamper 26 is located between the standby position and the transport position, and the film 100 is sandwiched between the first moving clamper 26 and the second fixed clamper 29 or the first moving clamper 26 and the second moving clamper 30. Then, at T3, the first moving clamper 26 can be moved to the left for a predetermined time to eliminate the slackness of the film 100.

  However, as described above, when the second moving clamper 30 is moved to the right from the standby position at T3, the tension is applied to the film 100 (when the slack is eliminated) and the like. Since the second moving clamper 30 holds the film 100 in any case when the film 100 is transported, the operation of applying tension to the film 100 and the transporting operation of the film 100 are performed as a continuous operation to shorten the work time. be able to.

  Further, by performing an operation in which the second moving clamper 30 is moved to the right from the standby position at T3, the second moving clamper is applied both when a tension is applied to the film 100 and when the film 100 is transported. Since the film 30 clamps the film 100 and moves the film 100 in the same direction in any operation, the control can be facilitated.

[Other forms of film transport apparatus]
In the above, the film conveying apparatus 1 in which the peeling part 7, the sticking peeling part 8 and the sticking part 9 are provided between the inlet side grip feeder 22 and the outlet side grip feeder 23 is shown as an example, but the present invention is applied. The film transporting apparatus is not limited to the configuration in which the peeling part 7, the sticking / peeling part 8, and the sticking part 9 are provided. The film transport apparatus to which the present invention is applied includes, for example, a configuration in which any one or more of a peeling unit 7, a bonding peeling unit 8, and a bonding unit 9 are provided, or a peeling unit 7, a bonding peeling unit 8, and a bonding unit. A configuration in which a plurality of at least one of 9 is provided may be used.

  Thus, in the film transport apparatus 1 of the type in which the peeling part 7, the sticking peeling part 8 and the sticking part 9 are provided between the inlet side grip feeder 22 and the outlet side grip feeder 23, the inlet side grip feeder 22 and the outlet side are provided. Since the film 100 from which the slack has been eliminated is conveyed by the grip feeder 23, the film 100 can be stably conveyed by eliminating the slack and meandering deformation of the film 100 while ensuring a satisfactory processing function for the film 100. Can be secured.

  In addition, the structure to which none of the peeling part 7, the sticking peeling part 8, and the sticking part 9 is provided may be sufficient as the film conveying apparatus with which this invention is applied, for example.

  Moreover, although the peeling part 7, the sticking peeling part 8, and the sticking part 9 were shown above the base 2 at the above, for example, as shown in FIG. 8 and affixing part 9 are arranged inside base 2 (below the upper surface of base 2), and entrance side grip feeder 22 and outlet side grip feeder 23 are arranged below the upper surface of base 2 It is also possible to make it. In addition, in FIG. 13, the film conveying apparatus 1A in which only the sticking part 9 was provided inside the base 2 is shown as an example. In the film transport apparatus 1A, for example, a pair of pull-in rollers 24, 24 are provided on the entrance-side grip feeder 22 so as to be separated from each other in the left-right direction. Are provided at the left and right ends of the base 2 and supported by the support portions 34, 34, respectively. The upper surface of the base 2 serves as a passage path for the adhesive film 200. A through hole 2a is formed.

  Since the peeling part 7, the sticking / peeling part 8, and the sticking part 9 are arranged inside the base 2 in this way, the peeling part 7, the sticking / peeling part 8 and the sticking part 9 do not exist outside the base 2. Further, it is possible to reduce the size of the film transport apparatus 1A.

  Further, in the film transport apparatus 1A, the positions of the entrance-side grip feeder 22 and the exit-side grip feeder 23 in the vertical direction differ with respect to the vertical positions of the peeling portion 7, the sticking peeling portion 8, and the sticking portion 9 in the film. Although the film 100 is transported in a non-straight state, even when the film 100 is not in a straight line, a stable transport state of the film 100 can be secured by applying tension to the film 100 while ensuring miniaturization.

  Further, for example, in the film transport apparatus to which the present invention is applied, a press part 36 that shears a part of the film 100 is replaced with the entrance-side grip feeder 22 instead of the peeling part 7, the sticking / peeling part 8, or the sticking part 9. And a film conveying apparatus 1B provided between the outlet side grip feeder 23 (see FIG. 14).

  In the film transport apparatus 1 </ b> B, a part of the film 100 drawn from the inlet side grip feeder 22 is sheared by the press portion 36 and pulled out from the outlet side grip feeder 23.

  Even in the film transport apparatus 1B of the type in which the press portion 36 is provided between the entrance-side grip feeder 22 and the exit-side grip feeder 23 as described above, slack and the like are eliminated by the entrance-side grip feeder 22 and the exit-side grip feeder 23. Since the film 100 is transported, it is possible to secure a good processing function for the film 100 and to eliminate deformations such as slack and meandering of the film 100 to ensure a stable transport state of the film 100.

  In the inlet side grip feeder 22, the first fixed clamper 25 and the first moving clamper 26 may be positioned on the side closer to the press portion 36 in the left-right direction. Any one of the two fixed clampers 29 and the second moving clamper 30 may be positioned on the side closer to the press portion 36 in the left-right direction.

  However, the first fixed clamper 25 is positioned closer to the press unit 36 than the first moving clamper 26, and the second fixed clamper 29 is positioned closer to the press unit 36 than the second moving clamper 30. By doing so, the tension of the film 100 can be kept constant at the bottom dead center of the press portion 36, and the quality of the film 100 can be improved. In particular, in the pressing process, the pressing process is performed in a state where the film 100 is sandwiched between the first fixed clamper 25 and the second fixed clamper 29, so that the film 100 is close to the pressing unit 36 in a state where a tension is applied. Since the film 100 is sandwiched between the first fixed clamper 25 and the second fixed clamper 29 positioned on the side, the film 100 can be pressed in a state where a stable tension is applied. It is effective for improving the quality of

  Further, for example, in the film transport apparatus to which the present invention is applied, at least one of the peeling part 7, the sticking / peeling part 8, or the sticking part 9 and the press part 36 are provided between the inlet-side grip feeder 22 and the outlet-side grip feeder 23. The film conveying apparatus 1C may be used (see FIG. 15). In addition, in FIG. 15, 1 C of film conveying apparatuses by which the press part 36, the peeling part 7, the sticking peeling part 8, and the sticking part 9 are arrange | positioned in order are shown as an example.

  In the film conveying apparatus 1C, since at least one work of the peeling unit 7, the sticking / peeling unit 8 or the sticking unit 9 and the pressing process of the press unit 36 are continuously performed, workability improvement and work time for the film 100 are improved. In addition to ensuring a good processing function for the film 100, it is possible to eliminate deformations such as slack and meandering of the film 100 and to ensure a stable conveyance state of the film 100.

[Summary]
As described above, in the film transport apparatuses 1, 1 </ b> A, 1 </ b> B, and 1 </ b> C, a part of the film 100 is sandwiched in a surface contact state and the first moving clamper 26 or the second moving clamper 30. At least one of the first moving clamper 26 and the first moving clamper 26 is in a state in which the film 100 is clamped by the first moving clamper 26 and the second moving clamper 30 by applying tension to the film by being set and moved. The second moving clamper 30 is moved in the transport direction in synchronization.

  Therefore, deformation such as slack and meandering of the film 100 can be eliminated, and a stable conveyance state of the film 100 can be ensured.

  In addition, the first fixed clamper 25, the first moving clamper 26, the second fixed clamper 29, and the second moving clamper 30 are movable units 25a, 26a, 29a, 30a that can move in directions perpendicular to the conveying direction, respectively. And fixed portions 25b, 26b, 29b, and 30b that are immovable in a direction orthogonal to the transport direction.

  Accordingly, since only the movable portions 25a, 26a, 29a, 30a are configured to be movable in the direction orthogonal to the transport direction, the first fixed clamper 25, the first movable clamper 26, and the second fixed clamper 29 are configured. And the structure of the 2nd movement clamper 30 is simple, and it can aim at simplification of the structure of the film conveying apparatuses 1, 1A, and 1B, and reduction of manufacturing cost.

  Further, the first fixed clamper 25 or the second fixed clamper 29 is set in a holding state, the film 100 is held in a surface contact state, and the first moving clamper 26 or the second moving clamper 30 is moved. By applying tension to the film 100, one part of the two parts of the film 100 sandwiched in a surface contact state is not moved in the transport direction and the direction opposite to the transport direction.

  Accordingly, the film 100 is held in a stable state by the first fixed clamper 25 or the second fixed clamper 29 to apply tension, and simplifies the control in the operation at the time of applying tension to the film 100. Can do.

  Furthermore, a tension is applied in a state where the film 100 is sandwiched between the first fixed clamper 25 and the second moving clamper 30, or the film 100 is sandwiched between the second fixed clamper 29 and the first moving clamper 26. By adopting a configuration in which tension is applied in a state in which the film 100 is applied, the lengths of the two portions of the film 100 held in a surface contact state are increased.

  Accordingly, the transport stroke of the film 100 in one cycle of the transport operation can be increased, and the workability of the film transport apparatus 1 for the film 100 can be improved and the work time can be shortened.
