  As will be described later, the push roll 30 is fed from the first feed roll 10 by moving to the inside of the main surface 5S along the main surface 5S of the support substrate 5 under the control of the control device 100. The first film F1 (more specifically, the first base film BF1) is pushed in. As will be described later, the cutter 40 cuts the first film F1 (more specifically, the first base film BF1) fed from the first feeding roll 10 under the control of the control device 100. To do. The pushing roll 30 and the cutter 40 are not arranged on the support substrate 5 and do not rotate with the rotation of the support substrate 5.

  The control device 100 includes the support substrate 5, the first feeding roll 10, the first winding roll 15, the second feeding roll 20, the second winding roll 25, the pushing roll 30, and the cutter 40. Control. Therefore, as shown in FIG. 2, the control device 100 includes a support substrate 5, a first feeding roll 10, a first winding roll 15, a second feeding roll 20, a second winding roll 25, At least electrically connected to each of the push roll 30 and the cutter 40.

The operation of each part of the control device 100 will be described later.

  Note that the control device 100 is mainly configured by a computer including a CPU, a ROM, a RAM, and the like, for example. The operation (function) of the control device 100 is realized by, for example, executing a predetermined program in the computer.

  Then, the film conveyance method which the control apparatus 100 of the film conveyance apparatus 1 implements is demonstrated. FIG. 4 is a flowchart showing the main steps of the film transport method. 5-8 is a figure for demonstrating each process of the film conveyance method. Hereinafter, FIGS. 4 to 8 will be referred to as appropriate. In this film transport method, first, as shown in FIG. 5A, the first film F1 is fed out from the first feed roll 10 and the second feed roll 20 as an initial state. The second film F2 is not fed from the state.

  More specifically, in this initial state, the first base film in a state where the first protective film PF1 is peeled off by rotating the first feeding roll 10 by the feeding roll control unit 110 of the control device 100. The material film BF1 is fed from the first feeding roll 10 to the conveyance path, and the winding roll control unit 115 of the control device 100 is peeled off from the first base film BF1 by rotating the first winding roll 15. The wound first protective film PF1 is wound up. The first base film BF1 fed out to the conveyance path is conveyed while being guided by a predetermined guide roll G.

  In such a state where the first base film BF1 is being fed from the first feeding roll 10, for example, the remaining amount of the first film F1 wound around the first feeding roll 10 is reduced to a predetermined amount or less. When this is done, the support substrate controller 105 of the control device 100 rotates the support substrate 5 (step S101 in FIG. 4). More specifically, in this step S101, the support substrate controller 105 determines the position of the second feeding roll 20 in the state where the first base film BF1 is fed from the first feeding roll 10. The support substrate 5 is rotated so that the position of the first feeding roll 10 is switched.

  Here, as shown in FIGS. 5B to 6A, the positions of the first feeding roll 10 and the second feeding roll 20 are obtained by rotating the support substrate 5 by about 180 °. Replace each other. At this time, the first base film BF1 fed from the first feed roll 10 is regulated by the first regulation roll 17 located on the outer side in the radial direction of the support substrate 5 than the first winding roll 15. Thus, contact with the first protective film PF1 is reliably suppressed.

  Subsequently, after the position of the second feeding roll 20 and the position of the first feeding roll 10 are switched, the feeding roll control unit 110 of the control device 100 adjusts the rotation speed of the second feeding roll 20 ( Step S102 in FIG. More specifically, in this step S102, the feeding roll control unit 110 performs the second feeding so that the rotation speed of the second feeding roll 20 becomes equal to the conveyance speed of the first base film BF1. The rotational speed of the roll 20 is adjusted.

  Subsequently, after the position of the second feeding roll 20 and the position of the first feeding roll 10 are switched and the rotational speed of the second feeding roll 20 is adjusted, the pushing roll control unit 130 of the control device 100 is The pushing roll 30 is pushed in (step S103 in FIG. 4). More specifically, as shown in FIG. 6B, in this step S <b> 103, the pushing roll control unit 130 removes the first base film BF <b> 1 fed from the first feeding roll 10. The second film F2 wound around the second feeding roll 20 by being pushed toward the second feeding roll 20 by the movement of the pushing roll 30 (more specifically, the second film F2 as described later). To the base film BF2).

  This step S103 will be described in more detail. FIG. 7 is a schematic cross-sectional view showing a contact state of the first base film. As shown in FIG. 7, first, the second film F2 wound around the second feed roll 20 is in a state where the outermost second protective film PF2 has been peeled off in advance. An adhesive such as a double-sided adhesive tape T is attached to the end E1 of the outermost second base film BF2 exposed by peeling off the second protective film PF2.

  Accordingly, when the push roll control unit 130 moves the push roll 30 to push the first base film BF1 toward the second feed roll 20 to contact the second base film BF2, the second base film BF2 is brought into contact with the second base film BF2. The end E1 of the material film BF2 is bonded to the first base film BF1 by the double-sided adhesive tape T. The second base film BF2 adhered to the first base film BF1 is fed out to the transport path together with the first base film BF1.

  That is, here, the pushing roll control unit 130 pushes the first base film BF1 fed from the first feeding roll 10 toward the second feeding roll 20 by the movement of the pushing roll 30. The second base film BF2 wound around the second feed roll 20 is brought into contact with the end part E1 of the second base film BF2 to be adhered to the first base film BF1.

  In the subsequent step, as shown in FIG. 6B, the end E1 of the second base film BF2 is bonded to the first base film BF1, and the second base film BF2 is the first base film BF2. In a state where the base film BF1 is fed out from the second feeding roll 20 together with the feeding of the base film BF1, the cutter control unit 140 of the control device 100 cuts the first base film BF1 using the cutter 40 (FIG. 4). Step S104). Thereby, only 2nd base film BF2 from the 2nd feeding roll 20 will be drawn out to a conveyance path. Therefore, the supply roll control unit 110 may stop the rotation of the first supply roll 10 and stop the supply of the first film F1 from the first supply roll 10.

  Subsequently, as shown in FIG. 8A, after the first base film BF <b> 1 is cut, the winding roll control unit 115 of the control device 100 performs the second operation on the second feeding roll 20. The 2nd winding roll 25 is moved so that the 2nd winding roll 25 may contact | abut on the 2nd protective film PF2 of the state superimposed on base film BF2 (process S105 of FIG. 4). At this time, the second winding roll 25 is provided with an adhesive such as a double-sided adhesive tape, for example. Therefore, the second protective film PF2 overlaid on the second base film BF2 is adhered to the second take-up roll 25 side, and thereafter peeled off from the second base film BF2 2 is wound on the winding roll 25.

  That is, here, the take-up roll control unit 115 of the control device 100 causes the second take-up roll 25 to come into contact with the second protective film PF2 in a state of being superimposed on the second base film BF2. By moving the second winding roll 25, the second protective film PF2 is adhered to the second winding roll 25 side and peeled off from the second base film BF2. At this time, the take-up roll control unit 115 applies the second take-up roll to the leading end E2 (see FIG. 7) in the transport direction of the second protective film PF2 wound around the second feed roll 20. The second winding roll 25 is moved at the timing when the 25 comes into contact.

  Thereafter, the pushing roll control unit 130 of the control device 100 moves the pushing roll 30 moved in the previous step S105 to the base position and separates it from the second feeding roll 20 (step S106 in FIG. 4). As a result, the second base film BF2 from which the second protective film PF2 has been peeled is fed out from the second feeding roll 20 to the transport path, and the second feeding film 10 is moved from the first feeding roll 10 to the second feeding film. Exchange to the feed roll 20 (paper splicing between the first film F1 and the second film F2) is completed.

  As described above, the film transport apparatus 1 according to the present embodiment includes the first feeding roll 10 and the second feeding roll 20 that respectively feed the first film F1 and the second film F2, and the first protection. A first take-up roll 15 and a second take-up roll 25 for winding the film PF1 and the second protective film PF2, respectively, a push roll 30, a cutter 40, and rolls 10, 15, 20, 25 are provided. And a control device 100 for controlling them. Further, the control device 100 includes a support substrate control unit 105, a push roll control unit 130, a cutter control unit 140, and a take-up roll control unit 115.

  The support substrate control unit 105 supports the first feeding roll 10 and the second feeding roll 20 so that the positions of the first feeding roll 10 and the second feeding roll 20 are interchanged in a state where the first base film BF1 is fed from the first feeding roll 10. The substrate 5 is rotated. The pushing roll control unit 130 pushes the first base film BF1 fed from the first feeding roll 10 after the positions of the first feeding roll 10 and the second feeding roll 20 are switched. 30 is pushed toward the second feeding roll 20 to be brought into contact with the second base film BF2 wound around the second feeding roll 20, and the end of the second base film BF2 E1 is adhered to the first base film BF1.

  The cutter control unit 140 uses the cutter 40 in the state in which the second base film BF2 is fed out together with the first base film BF1 by adhesion with the first base film BF1. Cut the film BF1. The winding roll control unit 115 cuts the first base film BF1, and then moves the second winding roll 25 so as to come into contact with the second feeding roll 20, thereby providing the second protective film PF2. Is adhered to the second winding roll 25 side and peeled off from the second base film BF2.

  As described above, according to the film transport apparatus 1, even if the films F1 and F2 include the base films BF1 and BF2 and the protective films PF1 and PF2, the transport of the base films BF1 and BF2 is stopped. By connecting the base films BF1 and BF2 without doing so, the feeding rolls 10 and 20 can be changed (that is, the sheets can be continuously spliced by the same apparatus). Further, it is not necessary to separately provide a unit for winding up the protective films PF1 and PF2. Furthermore, it is possible to switch by a simple method without requiring complicated work and space for exchanging the roll of film. For this reason, according to this film conveyance apparatus 1, the feeding rolls 10 and 20 can be changed, suppressing the increase in apparatus cost, the fall of productivity, and the increase in loss.

  Moreover, in the film conveyance apparatus 1 which concerns on this embodiment, the 2nd of the state by which the winding roll control part 115 of the control apparatus 100 was piled up on 2nd base film BF2 on the 2nd feeding roll 20 was carried out. The second take-up roll 25 is moved at such a timing that the second take-up roll 25 comes into contact with the tip E2 of the protective film PF2. For this reason, the second protective film PF <b> 2 can be reliably peeled off from the second base film BF <b> 2 and taken up by the second take-up roll 25.

  The above embodiment describes one embodiment of the film transport apparatus according to the present invention. Therefore, the film transport apparatus according to the present invention is not limited to the film transport apparatus 1 described above. The film transport apparatus according to the present invention can be modified from the above-described film transport apparatus 1 within a range not changing the gist of each claim.

  For example, in the above embodiment, the push roll 30 and the cutter 40 are not provided on the support substrate 5 and do not rotate with the rotation of the support substrate 5. However, the push roll 30 and the cutter 40 are not supported by the support substrate 5. The main surface 5 </ b> S may be provided so as to rotate as the support substrate 5 rotates.
