  As shown in FIG. 1, a mounting member 82 is fixed to the lower surface of the support member 20, and the corner 26a of the film 26 of the sheet 2 is peeled off from the sheet 2 and folded back to the mounting member 82 as shown in FIG. A detector 83 capable of detecting this is attached. The detector 83 measures, for example, the distance to the film 26 optically or by radio wave when the adhesive tape 42 on the peeling start end side is moved a predetermined amount in the direction of the peeling end side from the position pressed by the pressing means 54. The peeling of the corner portion 26a of the film 26 can be detected.

  Next, the operation of the film peeling apparatus 1 in the laminating apparatus 3 will be described. In the following description, it is assumed that a sheet laminated body in which a necessary number of sheets 2 are laminated from the beginning by the laminating apparatus 3 is manufactured. In the laminating apparatus 3, first, the first sheet 2 with film is placed on the first elevating table 12 of the first transport apparatus 9 located at the carry-in station 4 and is sucked and held. Then, the sheet with film 2 is conveyed to the temporary joining station 5 by the first conveying device 9. When the first elevating table 12 is conveyed to the temporary joining station 5, the first elevating table 12 is raised, the film-attached sheet 2 is sucked and fixed to the lower surface of the temporary joining device 21, and then the first elevating table 12 is moved. The table 12 starts to descend and returns to the loading station 4. In the temporary joining station 5, the delivered film-attached sheet 2 is aligned and positioned. At the carry-in station 4, the second sheet with film 2 is placed on the first elevating table 12. When the film-attached sheet 2 is transferred to the temporary joining device 21, the second lifting table 13 of the second transport device 10 is moved to the temporary joining station 5. The second elevating table 13 ascends at the temporary joining station 5 to suck and fix the film-attached sheet 2, and the film-attached sheet 2 is delivered from the temporary joining device 21. When the film-attached sheet 2 is transferred to the second elevating table 13, it moves down and moves to the peeling start station A.

  When the first sheet 2 with film is moved from the temporary joining station 5 to the separation start station A by the second conveying device 10, the first lifting table 12 on which the second sheet with film 2 is placed is the loading station 4. Then, the film-attached sheet 2 is transferred to the temporary joining station 21. When the film-attached sheet 2 is delivered to the temporary joining device 21, the first elevating table 12 moves to the carry-in station 4.

  When the second elevating table 13 moves to the peeling start station A, the peeling head 25 waiting on one end side of the actuator 33 moves to the bonding station D as shown in FIG. As shown in FIG. 6, the cylinder 39 is operated to move the sliding body 45 to the moving end on the peeling start end side, and the moving body 40 is positioned above the sheet with film 2 of the second elevating table 13 at the initial peeling start position on the peeling start end side. The adhesive tape 42 between the guide roller 52 and the guide roller 58 of the peeling head 25 is positioned above the sheet 2 with film so as to extend from the peeling start side corner 2a to the peeling end side corner 2b. In addition, the pressing tool 65c of the pressing means 54 is positioned above the peeling start side corner portion 2a of the sheet 2 with the adhesive tape 42 interposed therebetween. Here, the peeling start end side is the peeling start end side corner 2a side when the second lifting table 13 is located at the peeling start station A, and the peeling end side corner 2b side is the peeling end side. .

  In this state, the air cylinder 65 of the pressing means 54 is operated to lower the pressing tool 65c, and an intermediate portion of the adhesive tape 42 in which the pressing tool 65c extends between the guide roller 52 and the guide roller 58 is shown in FIG. In this way, the adhesive tape 42 is bonded to the peeling start side corner portion 26a of the film 26 of the film-attached sheet 2. When the pressing tool 65c pushes down the adhesive tape 42 between the guide roller 52 and the guide roller 58, the adhesive tape 42 between the guide roller 52 and the guide roller 58 is slightly stretched. The minute is given by the pulling lever 76 of the slack preventing means 59 being pulled back.

  After the adhesive portion of the adhesive tape 42 is adhered to the peeling start side corner portion 26a of the film 26, the air cylinder 65 of the pressing means 54 is operated to hold the pressing tool 65c in the raised position. Thereafter, the air cylinder 63 of the rotation preventing device 53 is operated to bring the pressing tool 63c into contact with the adhesive tape winding body 50, and the adhesive tape winding body 50 is pressed against the guide roller 52 to cause the adhesive tape winding body 50 to contact. To prevent free rotation. Note that the pressure-sensitive adhesive tape wound body 50 may be pressed by the rotation preventing device 53 before the pressure-sensitive adhesive tape 42 is pressed by the pressing means 54.

  Next, as shown in FIG. 8, the air cylinder 39 is operated to move the sliding body 45 to the moving end on the peeling end side, and the moving body 40 fixed to the sliding body 45 is moved to the initial peeling end position. . As the moving body 40 moves in the direction of the peeling end side, the tape support device 51, the guide roller 52, and the tape holding piece 55 are moved in the same direction as shown in FIG. 8, and the peeling start side corner portion 26a of the film 26 is moved. The end of the adhesive tape 42 on the peeling start end side is held by the tape holding piece 55 at a position close to the sheet 2 from the adhesive portion of the adhesive tape 42 adhered to the sheet 2 in the direction of the peeling end side (first peeling movement). As a result, the peeling start side corner portion 26a of the film 26 is abruptly folded back, and the peeling start end side corner portion 26a of the film 26 is peeled from the sheet 2, and the peeling start side corner portion of the folded film 26 is peeled off. The film 26 is peeled off from the sheet 2 by pulling and moving 26a toward the peeling end side. In this case, since the head main body 38 is held in position without being moved in the direction of the peeling termination side, the adhesive on the peeling termination side from the adhesive portion of the adhesive tape 42 adhered to the peeling start side corner portion 26a of the film 26 is maintained. The end portion of the tape 42 does not move in the direction of the peeling end side, and a tensile force in the direction of the peeling end side acts on the adhesive portion of the adhesive tape 42 bonded to the peeling start end side corner portion 26a of the film 26. There is nothing. Therefore, the trouble that the film 26 deforms or breaks the sheet 2 is prevented.

  Next, in conjunction with the second table moving device 17 and the head moving device 29, the second lifting table 13 is moved by the second table moving device 17 toward the peeling completion station B, that is, the temporary joining station 5, and the head. The actuator 33 of the moving device 29 is operated to move the slider 37 toward the separation / recovery station C in a direction crossing the movement locus L of the second lifting table 13. The movement of the second lifting table 13 by the second table moving device 17 and the movement of the peeling head 25 by the head moving device 29 cause the peeling head 25 to move from the peeling start side corner portion 26a to the peeling end side corner at a diagonal position. Relatively moves on the diagonal line of the sheet with film 2 toward the corner portion 26b. By the relative movement of the peeling head 25 toward the peeling end side corner portion 26b, the tape support device 51, the guide roller 52, the winding device 57, and the guide roller 58 of the peeling head 25 in the state shown in FIG. As a result, the end of the adhesive tape 42 on the peeling start end side is closer to the sheet 2 by the tape holding piece 55 than the adhesive portion of the adhesive tape 42 adhered to the peeling start end corner portion 26a of the film 26. While being held in position, the film 26 is continuously pulled and moved in the direction of the peeling end side, and the peeling start side corner portion 26a of the film 26 peeled off from the sheet 2 is further moved in the direction of the peeling end side to move the film 26 through the sheet 2 Will peel off. In this case, the adhesive tape 42 prevents the adhesive tape 42 from loosening even if the adhesive tape 42 on the peeling end side is likely to be loosened from the adhesive portion of the adhesive tape 42 adhered to the peeling start side corner portion 26a of the film 26. Since the pulling lever 76 of the means 59 hooks the adhesive tape 42 and pulls it sideways, the adhesive tape 42 between the guide roller 52 and the guide roller 58 is not loosened, and the lower adhesive surface of the adhesive tape 42 is the sheet. The trouble of pulling and moving the film 26 by adhering to the second film 26 can be prevented.

  As described above, the second lifting / lowering table 13 is moved to the peeling completion station B in conjunction with the second table moving device 17 and the head moving device 29, and the slider 37 is moved along the movement locus L of the second lifting / lowering table 13. When moved to the separation / recovery station C in the transverse direction, both end portions of the adhesive tape 42 on the separation start side and separation end side are moved in the direction of the separation termination side (second separation movement) from the adhesive portion, and the separation head 25 is separated and collected. At the station C, the entire surface of the film 26 is peeled off from the sheet 2, and the peeling start side corner portion 26 a of the peeled film 26 hangs down while being adhered to the adhesive tape 42 as shown in FIG. 9. In this case, the adhesive tape 42 on the peeling end side from the film adhesion portion absorbs the slackness when the pulling lever 76 of the slack preventing means 59 hooks the adhesive tape 42 and moves sideways, and the guide roller 52 and the guide roller 42 are absorbed. The adhesive tape 42 between 58 is maintained substantially horizontal. Next, the air cylinder 39 of the peeling head 25 is operated to move the moving body 40 toward the peeling start end side. As a result, the adhesive tape 42 between the guide rollers 52 and 58 is pulled toward the peeling start end side, and the pulling lever 76 of the loosening prevention means 59 is pulled back to the initial state shown in FIG. 9 is moved to a position H on the peeling start end side as shown in FIG.

  Next, the moving means 32 is operated to move the film holding means 31, and the suction pad 81 of the film holding means 31 is moved from the retracted position above the film collection container 30 to the suction holding position E below the peeling collection station C of the peeling head 25. Move to. As a result, the suction pad 81 of the film holding means 31 faces the rear surface of the film 26 that hangs down from the adhesive tape 42. In this state, suction is started and the peeled film 26 that hangs down from the peeling head 25 is sucked. Hold. That is, the film holding means 31 holds the film 26 that is peeled off from the sheet 2 by the movement of the adhesive tape 42 and hangs down from the intermediate portion of the substantially horizontal adhesive tape 42.

  After that, at the separation / recovery station C, the air cylinder 39 of the separation head 25 is operated again to move the moving body 40 toward the separation end side to obtain the film separation position shown in FIG. Due to the movement of the moving body 40 to the film separation position, the end of the adhesive tape 42 on the peeling start end side is moved in the same direction as the second peeling movement (direction away from the film 26). As a result, the adhesive tape 42 The film 26 is pulled away in a folded state, the adhesive portion of the adhesive tape 42 is smoothly peeled off from the film 26, and the film 26 is separated from the adhesive tape 42. In this case, the end of the adhesive tape 42 on the peeling start end side approaches the suction pad 81 of the film holding means 31, so that the film 26 is not pulled and the film 26 is moved by the movement of the adhesive tape 42. Separation can be ensured. In the above description, with the film 26 peeled off from the sheet 2 being held by the film holding means 31, the moving body 40 is moved in the same direction as the second peeling movement, and the adhesive tape on the peeling termination side from the adhesive portion. The adhesive tape 42 and the film 26 are separated from each other by leaving the film 42 away from the film 26. However, the film holding means 31 is moved toward or away from the peeling start side by a moving means (not shown) to move the film 26 to the adhesive tape 42. You may make it peel from. In the state of FIG. 6, as shown in FIG. 11, the peeling head 25 is further moved from the peeling collection station C to the peeling completion station J by the operation of the head moving device 29 (moved further back), and from the tape 42. It may be peeled off.

  Next, the suction pad 81 of the film holding means 31 is moved by the moving means 32 from the suction holding position E indicated by the solid line in FIG. 5 to the holding / release position F indicated by the phantom line in FIG. 2 above the film collection container 30. When the suction pad 81 is moved above the film collection container 30, the suction force of the suction pad 81 is released, and the film 26 held by the suction pad 81 is dropped into the film collection container 30 and collected. . In this case, if the film 26 is positively separated from the suction pad 81 by discharging air from the suction pad 81, the recovery operation of the film 26 can be accelerated. After the suction holding of the film 26 is released, the suction pad 81 is moved to the retracted position again by the moving means 32 as shown in FIGS. 3 and 4, and is prepared for holding the film 26 that is peeled next. Further, the peeling head 25 is moved again to one end side of the actuator 33 shown in FIG. 3 by the head moving device 29, so that the second lifting table 13 is positioned at the peeling start station. Note that the peeling head 25 may be moved to the bonding station D to prepare for the next film peeling of the sheet 2.

  Next, if necessary, the air cylinder 63 of the rotation prevention device 53 is operated to hold the pressing tool 63c in the raised position, and in this state, the air cylinder 73 of the winding device 57 is operated to perform a movable check. The claw 72 is temporarily protruded by a predetermined amount, and as a result, the movable check claw 72 rotates the ratchet gear 68a by rotating the claw by one pitch or more until the next claw is engaged with the check claw 71. The body 68 is rotated by a predetermined amount in the winding direction. By rotating the rotating body 68 in the winding direction, the adhesive tape winding body 56 winds up the adhesive tape 42 by a predetermined length, rotates the adhesive tape winding body 50 of the tape support device 51, and rotates the pressing means 54. The adhesive part of the pressure-sensitive adhesive tape 42 to be pushed down is changed to a new part. Therefore, the adhesive tape 42 can be reliably adhered onto the peeling start side corner portion 26a of the film 26 of each sheet 2. The winding of the adhesive tape 42 may be performed every time the film 26 of each sheet 2 is peeled off, or when the film 26 of a predetermined number of sheets 2 is peeled off or when the film 26 of an arbitrary number of sheets 2 is peeled off. You may make it do.

  When the film 26 is peeled from the first sheet 2 on the second lifting / lowering table 13, the first sheet 2 on which the second lifting / lowering table 13 is lifted and the film 26 is peeled off at the temporary joining station 5. Are superposed on the second sheet 2 with film, and then the two sheets 2 are temporarily joined by the temporary joining device 21. When the first sheet 2 and the second film-attached sheet 2 are temporarily joined, the second elevating table 13 is lowered while the laminated sheet 2 is sucked and held and moved to the laminating station 6 to be temporarily joined. The first sheet 2 and the second film-attached sheet 2 are thermocompression bonded by the press device 24. When the first sheet 2 and the second film-attached sheet 2 that have been temporarily joined are thermocompression bonded at the laminating station 6 by the press device 24, the second sheet 2 is thermocompression bonded with the film 26 attached thereto. By doing so, there is an effect of suppressing the thermal displacement of the sheet 2 to be small, and there is an effect of preventing the sheet 2 from sticking to the press device 24. Further, dust can be prevented from adhering to the sheet 2. Thereby, the lamination accuracy can be maintained with high accuracy, and the quality of the finally produced sheet laminate can be increased.

  On the other hand, while the first sheet 2 and the second film-attached sheet 2 are thermocompression bonded as described above, the third film-attached sheet 2 is transferred to the first conveying device 9 of the carry-in station 4. It is placed on the lifting table 12, transported to the temporary joining station 5, and the third sheet with film 2 is sucked and fixed to the temporary joining device 21 and delivered. When the third sheet 2 with film is delivered, the first elevating table 12 moves to the carry-in station 4.

  Next, the second lifting / lowering table 13 that sucks and holds the first sheet 2 and the second sheet 2 with film is moved to the peeling start station A. The second elevating table 13 has the second sheet with film 2 positioned at the top, and the second elevating table 13 is peeled in the same manner as the film 26 is peeled off from the first sheet with film 2. The film 26 is peeled from the second sheet with film 2 by the movement from the start station A to the peeling completion station B and the movement of the peeling head 25 in the direction crossing the movement locus L of the second lifting table 13. When the film 26 is peeled from the second sheet 2, the same operation as that of the sheet 2 from which the first film 26 has been peeled is performed. After the second and third film-attached sheets 2 are temporarily joined, they are thermocompression-bonded by the press device 24 at the laminating station 6. Then, by repeatedly carrying in, provisional joining, thermocompression bonding, and film peeling as described above a predetermined number of times, a sheet laminated body in which a necessary number of sheets 2 are finally laminated is formed. Thereafter, the formed sheet stack is held by the third transport device 11, transported from the stacking station 6 to the unloading station 7, and then transported from the stacking device 3. In addition, although a sheet | seat becomes thick because the some sheet | seat 2 is laminated | stacked, since the press tool 65c consists of an elastic member, it is not influenced so much by the change of the thickness of the sheet | seat 2 laminated | stacked at the time of adhesive tape sticking.

  In the above embodiment, the film 26 is moved by the relative movement with the peeling head 25 by moving the second elevating table 13 in the state where the sheet with film 2 is sucked and fixed toward the peeling completion station B from the peeling start station A. Although peeling has occurred, a peeling start station A and a peeling end station B are provided between the carry-in station 4 and the temporary joining station 5, the film peeling apparatus 1 is disposed at the peeling start station A, and the first lifting table 12 is provided with a film. The film 26 may be peeled off by moving the first elevating table 12 from the peeling start station A toward the peeling completion station B in a state where the sheet 2 is sucked and fixed. Moreover, although the adhesive body as a film holding means is comprised with the adhesive tape 42, it can also be comprised with the negative pressure adsorption | suction means adsorb | sucked with a negative pressure.
