The stopper plate 99 is connected to the electromagnetic solenoid 100 located immediately below the stopper plate 99 and can be moved in the vertical direction by the driving force of the electromagnetic solenoid 100. Normally, the upper end of the stopper plate 99 protrudes through the through hole 86 and the through hole 83 to the upper side of the horizontal guide plate 81 (when the electromagnetic solenoid 100 is demagnetized), and when the electromagnetic solenoid 100 is excited, the stopper plate 99 is lowered. Thus, the upper end of the stopper plate 99 moves to below the horizontal guide plate 82. Further, on the rear surface of the stopper plate 99, a micro switch (not shown) that detects the laminate film LF by contacting the front end of the laminate film LF between the horizontal guide plate 81 and the horizontal guide plate 82 is provided.

In addition, the circumferentially upper end portions of the feed roller 92, the feed roller 93, and the feed roller 96 are rotatably contacted. When the electromagnetic solenoid 117 is excited, the feed rollers 110, the feed rollers 111, and the feed rollers 114 rise through the through holes 83 and the notches 84, and the lower ends of the feed rollers 110, the feed rollers 111, and the feed rollers 114 are horizontal.

The feed roller 97, the feed roller 115, the feed roller 122, and the feed roller 123 are all connected to a motor M4 including a pulse motor through a rotational force transmission mechanism (not shown). When the motor M4 is rotated, the feed roller 97 is rotated. The feed roller 115, the feed roller 122, and the feed roller 123 rotate in the direction of the arrows in FIGS.

As shown in FIGS. 1, 2, and 15, a main switch MS is provided on the upper surface of the case 12. As shown in FIG. 15, the main switch MS is electrically connected to a control unit C configured by a CPU provided in the case 12. Further, the control unit C includes a motor M1, a motor M2, a motor M3, a motor M4, a sensor SA, a sensor SB, a sensor WS, an upper vacuum 78, a lower vacuum 79, an electromagnetic rotary solenoid 75, an electromagnetic solenoid 100, and an electromagnetic solenoid 117. , And the micro switch (micro switch provided on the stopper plate 99) is electrically connected.
As will be described later, the rotations of the motors M1 to M4 are controlled by a pulse signal that the control unit C transmits while managing the number of pulses.

Next, a laminating operation using the laminating apparatus 10 having the above configuration will be described.
First, a plurality of laminate films LF whose closed ends (folded portions) are located in the front and whose open ends are located in the rear are stacked on the hopper 36 in a vertically stacked state. The protective paper sheets A are placed in a state where they are stacked in the vertical direction.
When the main switch MS is turned on in this state, the motor M1, the motor M3, and the motor M4 rotate, the electromagnetic clutch is connected to the rubber roller 40, and the upper vacuum 78 and the lower vacuum 79 start the suction operation.

  With the rotation of the motor M1, the rubber roller 40, the feed roller 27, the feed roller 29, the feed roller 33, the feed roller 34, the feed roller 46, the feed roller 47, the feed roller 51, and the feed roller 52 are moved in the direction of the arrows in FIGS. Further, the front end portion of the first laminate film LF located at the uppermost position is automatically fed between the rubber roller 40 and the inclined guide plate 37 by the automatic feeding device provided in the hopper 36. Accordingly, the first laminate film LF is fed forward by the rotational force of the rubber roller 40. Then, after the first laminate film LF is sandwiched between the feed roller 46 and the feed roller 47, when the sensor SB detects the rear end of the first laminate film LF, the control unit C attaches the electromagnetic clutch to the rubber roller 23. The rubber roller 23 is rotated to the side (relative to the rubber roller 40 side is released and the rubber roller 40 is stopped), and the motor M2 is rotated after a predetermined time (first predetermined time) has passed. Then, the first protective paper sheet A located at the uppermost portion is automatically sent between the rubber roller 23 and the horizontal guide plate 20 by the automatic feeding device of the hopper 19 and is conveyed forward by the rubber roller 23.

  Before the linkage between the electromagnetic clutch and the rubber roller 40 is interrupted, the first laminate film LF is sandwiched between the feed roller 46 and the feed roller 47 and between the feed roller 51 and the feed roller 52. Therefore, even if this linkage is cut off, the first laminate film LF is inclined with respect to the guide surface 55 of the guide member 53 by the rotational force and inertial force of the feed roller 46, the feed roller 47, the feed roller 51, and the feed roller 52. It is sent between the guide parts 62 and stops when its front end comes into contact with the feed roller 66 and feed roller 68 that are stopped (before rotation).

The front end of the first laminate film LF is detected by the sensor WS until the front end of the first laminate film LF comes into contact with the feed rollers 66 and 68 and stops. Then, the control unit C stops the motor M1 after a predetermined time has elapsed (after the first protective paper sheet A is sandwiched between the feed roller 27 and the feed roller 29), and the first protective paper sheet A. Is stopped before the rear end of the protective paper sheet A is detected by the sensor SA.
As shown in FIG. 18, when the front end of the first laminate film LF comes into contact with the feed roller 66 and the feed roller 68 that are stopped (before rotation), as shown by the solid line in FIG. 18, the front end of the laminate film LF The entirety contacts the peripheral surfaces of the feed roller 66 and the feed roller 68. Therefore, even if the laminate film LF is inclined with respect to the transport direction (front-rear direction) as shown by the phantom line in FIG. 18, the contact causes the laminate film LF to face the front-rear direction (the laminate film LF The front end is facing left and right).

  After this (after the first predetermined time elapses), when the motor M2 rotates and the feed roller 66 and the feed roller 68 rotate, the laminate film LF is fed further forward by the rotational force of the feed roller 66 and the feed roller 68 ( (See FIG. 8). The first laminate film LF enters between the horizontal guide plate 81 and the horizontal guide plate 82 from between the rear ends of the horizontal guide plate 81 and the horizontal guide plate 82 while receiving negative pressure from the upper vacuum 78 and the lower vacuum 79, When moving further forward by the rotational force of the feed roller 110 and the feed roller 92 while being sandwiched between the feed roller 110 and the feed roller 92, the front end of the first laminate film LF is between the horizontal guide plate 81 and the horizontal guide plate 82. The stopper plate 99 is positioned at the rear surface of the stopper plate 99 so that the first laminate film LF is prevented from moving forward and stopped (the position of the laminate film LF at this time is the stop position).

At this time, since the front end of the first laminate film LF contacts the microswitch provided on the rear surface of the stopper plate 99, the control unit C restarts the rotation of the motor M1, and stops the rotation of the motor M2 and the motor M3. The electromagnetic solenoid 117 is excited simultaneously.
The motor M3 stops rotating, and the electromagnetic solenoid 117 is further excited to raise the feed roller 110, the feed roller 111, and the feed roller 114, and are separated from the feed roller 92, the feed roller 93, and the feed roller 96 (and the laminate film LF). Then, the forward moving force of the first laminate film LF is lost. Since negative pressure is applied from the upper vacuum 78 to the upper paper sheet F1 of the first laminate film LF, and negative pressure is applied from the lower vacuum 79 to the lower paper sheet F2, as shown in FIG. As described above, the rear end portion of the upper paper sheet F1 is sucked by the upper vacuum 78, and the rear end portion of the lower paper sheet F2 is sucked by the lower vacuum 79. As a result, the first laminate film LF The rear end portion is opened in a substantially V shape, and an insertion opening (rear end open portion) is formed at the rear end portion of the first laminate film LF.

When the motor M1 resumes rotation, the first protective sheet A is sandwiched between the feed roller 27 and the feed roller 29 and between the feed roller 33 and the feed roller 34, while the feed roller 27 and the feed roller. 29, the feed roller 33, and the feed roller 34 are rotated between the guide surface 54 and the inclined guide portion 58 of the guide member 53 and further sent between the horizontal guide portion 57 and the horizontal guide portion 61. At this time, when the sensor SA detects the rear end of the protective paper sheet A, the controller C connects the electromagnetic clutch to the rubber roller 40 (releases the linkage with the rubber roller 23 side and stops the rubber roller 23). The laminate film LF is conveyed forward, and the motor M2 is rotated again after a predetermined time (second predetermined time) has elapsed.
Even when the linkage between the electromagnetic clutch and the rubber roller 23 is cut off, the first protective sheet A is between the feed roller 27 and the feed roller 29 and between the feed roller 33 and the feed roller 34 before the linkage is cut off. Therefore, the first protective paper sheet A is guided by the rotational force and inertial force of the feed roller 27, feed roller 29, feed roller 33, and feed roller 34, and the guide surface 54 of the guide member 53 and the inclined guide portion. 58, and the front end stops by contacting the feed roller 66 and the feed roller 68 that are stopped (before rotation).

  When the front edge of the first protective paper sheet A comes into contact with the feed roller 66 and the feed roller 68 that are stopped (before rotation), the entire front edge of the protective paper sheet A is fed as in the case of the laminate film LF. Since the roller 66 and the feed roller 68 are in contact with the peripheral surfaces, even if the protective paper sheet A is inclined with respect to the transport direction (front-rear direction), it comes to face in the front-rear direction due to this contact (protective paper sheet) The front end of the body A faces in the left-right direction).

Thereafter, when the feed roller 66 and the feed roller 68 are rotated by the motor M2 (after the predetermined time has elapsed), the first protective paper sheet A is fed forward by the rotational force of the feed roller 66 and the feed roller 68, The first laminate film LF is inserted into the laminate film LF from the open end at the rear end. When the first protective paper sheet A moves to the front of the feed roller 66 and the feed roller 68 and loses the running force from the roller 66 and the feed roller 68, the first protective paper sheet A thereafter The forward movement is stopped in a state where the end portion protrudes (exposes) slightly from the rear end of the laminate film LF (for example, about 5 mm).
Further, when the rear end portion of the first protective paper sheet A passes the sensor WS, the sensor WS detects this, and the rear end portion of the first protective paper sheet A is fed by the feed roller 66 and the feed roller. After passing through 68, the controller C stops the rotation of the motor M1, and stops the second laminate film LF before the rear end reaches the sensor SB.

  When the first protective sheet A is stopped in this way, the control unit C excites the electromagnetic rotary solenoid 75. When the electromagnetic rotary solenoid 75 rotates in the direction of the arrow in FIG. 9, as shown in FIGS. 8 and 9, the tip of the push plate 73 that is normally positioned below the horizontal guide 61 passes through the notch 64 and the notch 60. It rotates forward (in the direction of the arrow in FIG. 7). 10, 13, and 14, the pressing plane 77 of the push-in plate 73 protects while elastically deforming the rear end portion of the upper paper sheet body F1 and the rear end portion of the lower paper sheet body F2. Abutting on the rear end of the paper sheet A, the protective paper sheet A is pushed forward. When the electromagnetic rotary solenoid 75 is rotated to the front rotation end, the electromagnetic rotary solenoid 75 is demagnetized (de-energized) by the control unit C, and the electromagnetic rotary solenoid 75 rotates rearward and returns to the initial position. Then, as shown by the phantom lines in FIGS. 11 and 14, the pressing plate 73 (pressing plane 77) is separated from the laminate film LF and the protective paper sheet A, so that the upper paper sheet F1 and the lower paper sheet F2 are separated. Returns to its original state, the rear end of the protective paper sheet A is positioned in front of the rear end of the laminate film LF, and the protective paper sheet A is completely stored in the laminate film LF.

  Further, the pressing plane 77 of the pressing plate 73 is a plane parallel to the generatrix and the radial direction of the rotating roller 72 at the connecting portion (adhering portion) between the pressing plate 73 and the rotating roller 72, and the rotating shaft 71 faces the left-right direction. Therefore, when the left and right pressing planes 77 press the rear end of the laminate film LF and the rear end of the protective paper sheet A forward, the directions of the laminate film LF and the protective paper sheet A are corrected. That is, as shown by the phantom line in FIG. 19, even if the laminate film LF is not accurately oriented in the front-rear direction before pressing, the front end of the laminate film LF is pressed by the stopper plate 99 after pressing as shown by the solid line in FIG. Therefore, the laminate film LF is accurately oriented in the front-rear direction (the front end and the rear end of the laminate film LF are directed in the left-right direction). Furthermore, although illustration is omitted, even if the protective paper sheet A is not accurately oriented in the front-rear direction before pressing, the front ends of the protective paper sheet A after pressing are mutually inside the laminate film LF. Since it is in contact with the inner surface of the close upper paper sheet F1 and the inner surface of the lower paper sheet F2 in the vicinity of the front end (a position away from the front end joint portion by the amount of adhesion), it is directed accurately in the front-rear direction. (So that the front end and the rear end of the protective paper sheet A are directed in the horizontal direction). That is, the rotary pusher 70 has not only a function of pushing the protective paper sheet A but also a function of correcting the direction of the laminate film LF and the protective paper sheet A.

  When the electromagnetic rotary solenoid 75 returns to the initial position, the control unit C excites the electromagnetic solenoid 100, demagnetizes the electromagnetic solenoid 117, stops the motor M2, and rotates the motor M1 and the motor M3 again. Then, the stopper plate 99 is lowered and the upper end thereof is positioned below the horizontal guide plate 82, and the feed roller 110, the feed roller 111, and the feed roller 114 are lowered through the through-hole 83 and the notch 84 to feed the feed roller 92. , The feed roller 93 and the feed roller 96 are brought into contact with each other, and the feed rollers 110, 111, 114, 92, 93, 96 are rotated in the direction of the arrows in FIGS. 1 and 3 by the driving force of the motor M3. Then, the first laminated film LF containing the protective paper sheet A is sandwiched between the feed roller 110 and the feed roller 92, the feed roller 111 and the feed roller 93, and the feed roller 114 and the feed roller 96. 110, the feed roller 92, the feed roller 111, the feed roller 93, the feed roller 114, and the feed roller 96 are transmitted to the first laminate film LF, and the first laminate film LF is fed forward. Further, the first laminate film LF is sandwiched between the feed roller 115 and the feed roller 97 that are rotated by receiving the driving force of the motor M 4, and the heater 118 is rotated by the rotational force of the feed roller 115 and the feed roller 97. Between the heater 119 and the heater 119, and is heated and pressed by the heater 118 and the heater 119 (see FIG. 12). Then, the peripheral portions of the upper paper sheet F1 and the lower paper sheet F2 are bonded to each other with the protective paper sheet A sandwiched therebetween, and the protective paper sheet A is laminated by the laminate film LF. The first laminate film LF that has passed between the heater 118 and the heater 119 is sandwiched between the feed roller 122 and the feed roller 123 that are rotated by the driving force of the motor M4, and the feed roller 122 and the feed roller. It is sent forward by the rotational force of 123 and discharged from the discharge port 17 to the outside of the case 12.

Further, since the motor M1 rotates again as described above, the second laminate film LF is conveyed forward by the rubber roller 40, the feed roller 46, the feed roller 47, the feed roller 51, and the feed roller 52, and the sensor SB is 2 When the rear end of the second laminated film LF is detected, the electromagnetic clutch is connected to the rubber roller 23 (breaking the link with the rubber roller 40), and the second protective paper sheet A is conveyed forward by the rubber roller 23. The
The second laminate film LF and the second protective paper sheet A are then transported forward in the same procedure as the first laminate film LF and the first protective paper sheet A. The eye protection paper sheet A is laminated by the second laminate film LF. Further, the third, fourth,... Laminate film LF and the protective paper sheet A are sequentially forwarded in the same procedure, and the protective paper sheet A is laminated by the laminate film LF.

  As described above, according to the laminating apparatus 10 of the present embodiment, the protective paper sheet A can be automatically pushed into the laminated film LF quickly and reliably by the pushing plate 73 rotated by the electromagnetic rotary solenoid 75. it can. Therefore, the laminating operation can be performed quickly and accurately.

In the above embodiment, the rotary pusher 70 is used as the rotary pressing means. However, the protective paper sheet A is pushed forward while elastically deforming the rear ends of the upper paper sheet F1 and the lower paper sheet F2. If it exists, you may use the thing of the structure other than the above.
Further, a stopper plate other than the stopper plate 99 is provided with its front and rear positions shifted from the stopper plate 99 (the micro switch is provided on the rear surface of each stopper plate), and an electromagnetic solenoid is connected to each stopper plate. If a known keyboard that electrically connects the solenoid to the control unit C and inputs the longitudinal dimension of the laminated film used for the case 12 is provided, the longitudinal dimension differs from the laminated film LF by the laminating apparatus 10. Laminate film can be laminated.
