The tensile force F3 applied to the laminated film 15 is detected by a tension detector 47 and the tensile force F1 is made relatively weaker than the tensile force F2 corresponding thereto by the controller 38 so that the laminated film 15 is not excessively tensioned and loosened. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a laminating apparatus for adhering a resin film to one surface of a flat plate member.

  In an imaging plate (storable phosphor panel) used instead of a flat member, for example, an X-ray film, a stimulable phosphor layer is formed on a plastic support, and the top surface of the stimulable phosphor layer is A protective layer made of transparent resin is formed, and a light shielding layer made of black resin mixed with carbon black is formed on the back surface of the support.

  The imaging plate is exposed with an X-ray image of a human body or the like during X-ray imaging. The stimulable phosphor layer accumulates incident X-ray energy, and emits fluorescence having an intensity corresponding to the accumulated X-ray energy when irradiated with excitation electromagnetic radiation such as a laser during image reading. An X-ray image can be reproduced by reading this fluorescence.

  Since the light shielding layer is formed by coating, it is preferable to provide a protective layer on the upper surface (the back surface of the imaging plate) as well as the upper surface of the stimulable phosphor layer. In order to provide this protective layer, conventionally, a resin film was laminated on the surface of the light shielding layer while the imaging plate was turned upside down and conveyed with the light shielding layer facing upward.

  When laminating a resin film on the surface of the light shielding layer, in order to ensure the flatness of the imaging plate, it is necessary to place the imaging plate on a planar guide plate and transport it by a roller pair. However, since the upper surface of the stimulable phosphor layer (the surface of the imaging plate) is pressed against or rubbed against the surface of the guide plate, the upper surface of the stimulable phosphor layer is protected by the protective layer. However, the occurrence of pushing and scratches is unavoidable, leading to a reduction in product quality of the imaging plate.

  On the other hand, there is known a laminating apparatus that laminates a thin resin film (laminate film) on both surfaces of cards such as a license and paper such as a certificate of recognition (Patent Document 1).

Registered Utility Model No. 3088064

  Patent Document 1 does not disclose a configuration for how to support and convey cards and papers toward the laminating position, and is an imaging plate laminate in which there is a risk of occurrence of pressing scratches or scratches. In addition, the invention described in Patent Document 1 cannot be applied as it is.

  In addition, when laminating a relatively short flat plate member such as an imaging plate continuously, the tension applied to the laminating film changes intermittently, so that the laminating film tends to be loosened. There is a problem of causing wrinkles.

  An object of the present invention is to provide a laminating apparatus capable of performing high-quality laminating without wrinkles while minimizing pressing scratches and scratches on the surface of a flat plate member with a simple configuration. .

  The laminating apparatus of the present invention is provided with a driving roller that rotates so as to contact one surface of the flat plate member and move the flat plate member in a certain direction, and to face the drive roller. A driven roller that is biased toward the driving roller to a predetermined interval that is narrower than the thickness and does not contact the driving roller, and the adhesive surface of the adhesive film faces the driving roller between the driving roller and the driven roller. As described above, with the end of the adhesive film placed on the peripheral surface of the driven roller, the flat plate member is inserted between the drive roller and the driven roller, so that the flat plate member The flat plate member is nipped by the driven roller and conveyed in a fixed direction by the rotation of the driving roller. At the same time, the adhesive film is moved to the other side of the flat plate member while the driven roller rotates. Characterized in that it adhered to.

The end of the adhesive film is placed on the peripheral surface of the driven roller between the driven roller to be urged and the drive roller and the driven roller so that the adhesive surface of the adhesive film faces the drive roller. In this state, a film that gives a tensile force F1 to the adhesive film with release paper by applying a rotational force to the film roll in a direction to wind up the adhesive film with release paper. A separation roller provided between the film roll driving device, the film roll and the driven roller, and for peeling the release paper from the adhesive film; and in the direction of winding the release paper peeled from the adhesive film by the separation roller A flat plate member is not inserted between the drive roller and the driven roller, and the release paper take-up roller rotation driving device that applies a rotational force to the release paper take-up roller to give a pulling force F2 to the release paper. In this state, the adhesive films are prevented from moving by making the pulling forces F1 and F2 the same, and the flat plate member is driven by inserting the flat plate member between the driving roller and the driven roller. The flat plate member is conveyed in a fixed direction by the rotation of the driving roller, and at the same time the driven roller is driven. The adhesive film is adhered to the other surface of the flat plate member while rolling, and the tensile force F1 is relatively larger than the tensile force F2 by the amount of the tensile force F3 applied to the adhesive film along with the adhesion. A weakening control device is provided.

  Further, when the flat plate-like member which is arranged above the transfer track for transferring the flat plate-like member and floats above the transfer track is brought into contact with the upper surface of the flat plate-like plate, A driving roller that rotates so as to move the member in a fixed direction, and is provided opposite to the driving roller, and is attached to the driving roller to a predetermined interval that is narrower than the thickness of the flat plate-like member and does not contact the driving roller. An end of the adhesive film on the peripheral surface of the driven roller so that the adhesive surface of the adhesive film faces the drive roller side between the driving roller and the driven roller. The flat plate member is sandwiched between the driving roller and the driven roller by inserting the flat plate member between the driving roller and the driven roller in a state of being placed, and the flat plate shape is formed by the rotation of the driving roller. At the same time timber is conveyed in a predetermined direction, the driven roller is characterized in that the adhesive film while rotated stuck to the lower surface of the plate-like member.

  Also, a film roll in the form of a roll of a long adhesive film with release paper, a release paper winding roller for winding the release paper peeled off from the adhesive film, and a transport track for transporting the flat plate member When the flat plate member arranged above and transported on the transport track floats above the transport track, it rotates so as to contact the upper surface of the flat plate member and move the flat plate member in a certain direction. A driving roller, a driven roller provided below the driving roller and biased toward the driving roller to a predetermined interval that is narrower than the thickness of the flat plate member and does not contact the driving roller; and the driving roller; With the end of the adhesive film placed on the peripheral surface of the driven roller so that the adhesive surface of the adhesive film faces the drive roller side with the driven roller, the adhesive film with the release paper is placed. A film roll rotation driving device that applies a tensile force F1 to the adhesive film with the release paper by applying a rotational force to the film roll in the direction of winding the film, and is provided between the film roll and the driven roller; A separation roller that peels the release paper from the adhesive film, and a pulling force applied to the release paper by applying a rotational force to the release paper take-up roller in the direction of winding the release paper peeled off from the adhesive film by the separation roller. In the state in which the release sheet take-up roller rotation driving device for applying F2 and the flat plate member are not inserted between the driving roller and the driven roller, the adhesive films do not move with the same pulling force F1, F2. The flat plate member is driven by inserting the flat plate member between the driving roller and the driven roller. The flat plate member is nipped between the roller and the driven roller and conveyed in a certain direction by the rotation of the driving roller. At the same time, the adhesive film is adhered to the lower surface of the flat plate member while the driven roller is driven to rotate. As a result, there is provided a control device for making the pulling force F1 relatively weaker than the pulling force F2 by the amount of the pulling force F3 applied to the adhesive film.

  The laminating apparatus of the present invention is provided with a driven roller that is biased toward the driving roller to a predetermined interval that is smaller than the thickness of the flat member and does not contact the driving roller, and the flat member is interposed between the driving roller and the driven roller. The flat plate member is sandwiched between the driving roller and the driven roller by inserting, and the flat plate member is conveyed in a certain direction by the rotation of the driving roller. At the same time, the driven roller sticks the adhesive film to one side of the flat plate member. However, since the driven rotation is carried out, it is not necessary to press the flat plate member against the guide plate when the adhesive film is stuck, and it is possible to minimize pressing and scratching on the surface of the flat plate member.

  Further, a driven roller that is biased toward the drive roller to a predetermined interval that is smaller than the thickness of the flat plate member and does not come into contact with the drive roller is provided, and the flat plate is inserted by inserting the flat plate member between the drive roller and the driven roller. The plate-like member is sandwiched between the drive roller and the follower roller, and the plate-like member is conveyed in a certain direction by the rotation of the drive roller. Therefore, it is not necessary to press the flat plate member against the guide plate when adhering the adhesive film, and it is possible to minimize the scratches and scratches on the surface of the flat plate member, and the adhesive film with release paper and A tensile force is applied to each of the release papers so that they are balanced with the release paper, and the flat plate member is inserted between the driving roller and the driven roller to attach the adhesive plate to the flat plate member. While the film is being applied, the tensile force applied to the adhesive film with the release paper is relative to the tensile force applied to the release paper by the amount that the adhesive film is pulled along with the application. Therefore, it is possible to achieve a high-quality laminate without causing the adhesive film to be too tight and not to be loosened and wrinkled.

  In addition, when the flat plate member that has been transported on the transport track floats above the transport track, the drive roller contacts the upper surface of the flat plate member and moves the flat plate member in a certain direction, and the drive roller There is provided a driven roller that is provided facing down and is biased toward the driving roller to a predetermined interval that is narrower than the thickness of the flat member and does not contact the driving roller, and the flat member is disposed between the driving roller and the driven roller. The flat plate member is sandwiched between the driving roller and the driven roller, and the flat plate member is conveyed in a certain direction by the rotation of the driving roller. At the same time, the driven roller applies the adhesive film to the lower surface of the flat plate member. Since it rotates while being attached, there is no need to press the flat plate member against the guide plate when attaching the adhesive film, and it minimizes the scratches and scratches on the upper surface of the flat plate member. Door can be.

  In addition, when the flat plate member that has been transported on the transport track floats above the transport track, the drive roller contacts the upper surface of the flat plate member and moves the flat plate member in a certain direction, and the drive roller There is provided a driven roller that is provided facing down and is biased toward the driving roller to a predetermined interval that is narrower than the thickness of the flat member and does not contact the driving roller, and the flat member is disposed between the driving roller and the driven roller. The flat plate member is sandwiched between the driving roller and the driven roller by being inserted into the plate, and the flat plate member is conveyed in a certain direction by the rotation of the driving roller. Because it is attached to the lower surface of the plate, there is no need to press the flat plate member against the guide plate when adhering the adhesive film, minimizing the scratches and scratches on the upper surface of the flat plate member. In order to balance the adhesive film with release paper and the release paper, a tensile force is applied to each, and the flat plate member is inserted between the driving roller and the driven roller to form the flat plate member. While the adhesive film is being applied, the tensile force applied to the adhesive film with release paper is greater than the tensile force applied to the release paper, as much as the adhesive film is pulled with the application. However, the adhesive film does not become too tight and does not slack, and a high-quality laminate without wrinkles on the lower surface of the flat plate member can be performed.

  The flat plate member to be laminated by the laminating apparatus according to the embodiment of the present invention is a rectangular imaging plate 10. As shown in FIG. 1, the imaging plate 10 has a stimulable phosphor layer 12 formed on a plastic support 11, and a protective layer 13 made of a transparent resin on the upper surface. . A black resin light shielding layer 14 mixed with carbon black is provided on the lower surface of the support 11. The light shielding layer 14 absorbs the fluorescence emitted from the stimulable phosphor layer 12. The surface of the protective layer 13 is the upper surface 10a of the imaging plate 10, and the surface of the light shielding layer 14 is the lower surface 10b of the imaging plate 10.

  As shown in FIG. 2, the laminate film 15 attached to the lower surface 10b of the imaging plate 10 is a transparent thin resin film formed of, for example, PET, and an adhesive 16 is applied to one side thereof. A release paper 17 is provided on the adhesive 16. The laminate film 15 with the release paper 17 is supplied to the laminating apparatus as a film roll 19 wound around a cylindrical winding core 18 so that the release paper 17 is on the outside.

  In the laminating apparatus of the present invention, as shown in FIG. 3, a guide plate 21 is disposed above the film roll 19 so as to extend in the horizontal direction. The upper surface 21a of the guide plate 21 is formed in a flat shape with high smoothness. Further, in the middle of the guide plate 21, holes 21b and 21c are formed.

  A pair of conveying rollers 24 is disposed in the hole 21b. The transport roller pair 24 sandwiches the imaging plate 10 so that the lower surface 10b of the imaging plate 10 slightly floats from the upper surface 21a of the guide plate 21 and transports the imaging plate 10 to the left in the drawing. A specially processed non-woven fabric is provided on the peripheral surfaces of the conveying roller pair 24, and the non-woven fabric captures dust, dust, and the like adhering to both surfaces of the imaging plate 10, and the imaging plate 10 just before the laminating processing is captured. Clean both sides. Note that a nonwoven fabric may be provided on only one roller of the transport roller pair 24 and only the lower surface 10b of the imaging plate 10 to be laminated may be cleaned.

  In the hole 21c, a driving roller 25 and a driven roller 26 for laminating are arranged so as to face each other, and a reflective sensor 27, a cutter 28, and a conveying roller pair 29 are arranged downstream thereof. Similarly to the transport roller pair 24, the transport roller pair 29 sandwiches the imaging plate 10 so that the lower surface 10b of the imaging plate 10 slightly floats from the upper surface 21a of the guide plate 21, and transports the imaging plate 10 to the left in the drawing. The sensor 27 can also be a transmissive type.

  Below the guide plate 21, a release shaft take-up roller 33 for winding the release paper 17 peeled off from the laminate film 15 by the separation roller 32 is disposed in addition to the drive shaft 31 to which the core 18 of the film roll 19 is attached. Has been. With this arrangement, the center of gravity of the laminating apparatus is lowered to the lower part, and the apparatus is stabilized, and the relatively large film roll 19 and the release paper winding roller 33 are not positioned in front of the operator. No longer feels pressure.

  The drive shaft 31 is given a rotational force in the direction in which the winding core 18 winds the adhesive film 15 with the release paper 17 (clockwise in the drawing) by a drive motor 35 which is a film roll rotation drive device. A tensile force F <b> 1 is applied to the adhesive film 15 with the pattern paper 17.

  Further, the release paper take-up roller 33 is wound in a direction (counterclockwise in the drawing) in which the release paper 17 peeled off from the adhesive film 15 is taken up by a drive motor 36 which is a release paper take-up roller rotation drive device. A rotational force is given, and the release paper 17 is given a pulling force F2. The power supplied to the drive motors 35 and 36 is controlled by the controller 38 so that the pulling forces F1 and F2 are the same when the laminating operation is not performed.

  The laminate film 15 drawn from the film roll 19 is guided to the driven roller 26 by the guide rollers 41 to 45. The separation roller 32 is provided between the guide roller 44 and the guide roller 45.

  The guide roller 43 is provided with a tension detection device 47, which detects the tension applied to the guide roller 43 from the laminate film 15, converts it into an electrical signal (tension detection signal), and sends it to the control device 38. . Based on the tension detection signal, the control device 38 adjusts the electric power supplied to the drive motor 35 and adjusts the pulling force F1 so that the laminate film 15 is not slackened.

  In FIG. 4, which shows an enlarged view of the vicinity of the drive roller 25 and the driven roller 26, the drive roller 25 is always rotated clockwise around a shaft 49 by a drive motor (not shown) immediately after power is supplied to the laminating apparatus. . One driven roller 26 is rotatably provided on the shaft 51. One end of the shaft 51 is fixed to a moving plate 52 provided so as to be movable in the vertical direction. A spring device 53 that biases the moving plate 52 upward is attached to the moving plate 52 via an arm 54.

  The moving plate 52 is provided with a pin 52a, and the minimum distance d1 between the driven roller 26 and the driving roller 25 is set by the pin 52a coming into contact with the stopper 55. The minimum distance d1 is larger than 0.0 mm (the driven roller 26 and the driving roller 25 are not in contact) and smaller than the thickness d2 of the imaging plate 10 (for example, d2 = 0.7 mm). In the present embodiment, the minimum interval d1 is set to 0.5 mm, for example.

  By providing the minimum distance d1, the driven roller 26 does not rotate even when the driving roller 25 is always rotating, and only when the imaging plate 10 is inserted between the driving roller 25 and the driven roller 26. The rotation of the driving roller 25 is transmitted to the driven roller 26 via the imaging plate 10, and the driven roller 26 is driven to rotate.

  In a state where the imaging plate 10 is inserted between the driving roller 25 and the driven roller 26 and the driven roller 26 presses the imaging plate 10 against the driving roller 25, the imaging plate 10 is slightly more than the upper surface 21 c of the guide plate 21. However, the position of the shaft 49 of the drive roller 25 is set so as to float upward. This prevents the lower surface 10b of the imaging plate 10 from being pressed against the upper surface 21c of the guide plate 21 during lamination, which will be described later, and prevents the lower surface 10b from being pressed or scratched. Further, since it is not necessary to reverse the front and back of the imaging plate 10 for laminating, the upper surface 10a is not pressed or scratched.

  When the imaging plate 10 is not inserted between the driving roller 25 and the driven roller 26, the end of the laminate film 15 comes into contact with the peripheral surface of the driven roller 26 by its own weight, and the adhesive layer 16 of the laminate film 15. Is directed to the drive roller 25 side (upward). In this state, the control device 38 controls the drive motors 35 and 36 so that the pulling forces F1 and F2 are the same. Further, since the end portion of the laminate film 15 is not pulled, the tension applied to the guide roller 43 from the laminate film 15 is zero.

  When the imaging plate 10 is inserted between the driving roller 25 and the driven roller 26 by the conveying roller pair 24, only the difference between the minimum distance d1 and the thickness d2 (0.7 mm−0.5 mm = 0.0 in this embodiment). 2 mm), the driven roller 26 is pressed against the driving roller 25, and the pressure-sensitive adhesive layer 16 of the laminate film 15 is pressed against the lower surface 10 b of the imaging plate 10 by the driven roller 26. At the same time, the imaging plate 10 is sandwiched between the driving roller 25 and the driven roller 26, and the rotation of the driving roller 25 causes the imaging film 10 to be conveyed to the left of the drawing, while the laminate film 15 is placed on the lower surface 10b of the imaging plate 10. It will be attached.

  As the laminate film 15 is attached to the lower surface 10b of the imaging plate 10, the laminate film 15 is pulled by the pulling force F3 (see FIG. 5), and tension is applied from the laminate film 15 to the guide roller 43. This tension is detected by the tension detector 47, and this tension detection signal is input to the controller 38.

  The control device 38 changes the electric power applied to the drive motor 35 based on the tension detection signal, and makes the tensile force F1 relatively weaker than the tensile force F2 by the amount of the tensile force F3. As a result, the laminate film 15 does not become too tight and does not loosen, and is drawn from the film roll 19, so that the laminate film 15 is adhered to the lower surface 10 b of the imaging plate 10 without wrinkles. Further, since the pulling force F2 is relatively stronger than the pulling force F1, the release paper 17 is wound around the release paper winding roller 33.

  Next, the operation of the above embodiment will be described. As shown in FIG. 3, the film roll 19 is set on the drive shaft 31, and then the laminate film 15 with the release paper 17 is pulled out from the film roll 19 and is passed around the guide rollers 41 to 44. The release paper 17 is peeled off from the laminate film 15 by a predetermined length at the position of the separation roller 32, and the release paper 17 is locked to the release paper winding roller 33. The end of the laminate film 15 from which the release paper 17 has been peeled is passed between the driving roller 25 and the driven roller 26, and is placed on the peripheral surface of the driven roller 26 so that the adhesive layer 16 faces the driving roller 25 side. Put.

  When the power switch of the laminating apparatus is turned on, the driving roller 25 is rotated at a constant speed in the clockwise direction. Further, the control device 38 makes the tensile force F1 applied to the laminate film 15 with the release paper 17 and the tensile force F2 applied to the release paper 17 the same so that the laminate film 15 with the release paper 17 and the release paper 17 are separated. The electric power supplied to the drive motors 35 and 36 is adjusted so as to be balanced at the position of the separation roller 32. Thereby, the laminate film 15 placed on the peripheral surface of the driven roller 26 is not subjected to any tension, and the laminate film 15 is stationary. Further, the driven roller 26 does not rotate due to the minimum distance d1 from the drive roller 25.

  The conveying roller pair 24 conveys the imaging plate 10 conveyed from the right side of the drawing along the upper surface of the guide plate 21 toward the driving roller 25 while cleaning both surfaces. As shown in FIG. 5, when the distal end portion of the imaging plate 10 is inserted between the driving roller 25 and the driven roller 26, the driven film 26 presses the laminate film 15 against the lower surface 10b of the imaging plate 10, and sticks. Is done. At this time, the imaging plate 10 is pushed upward by the driven roller 26, and a slight gap is formed between the lower surface 10 b of the imaging plate 10 and the upper surface 21 a of the guide plate 21.

  At the same time as the imaging plate 10 is conveyed to the left of the drawing by the rotation of the driving roller 25, the driven roller 26 is driven to rotate, and the driven roller 26 presses the adhesive layer 16 of the laminate film 15 against the lower surface 10b of the imaging plate 10, The laminate film 15 is stuck on the lower surface 10b of the imaging plate 10. This sticking is performed in a state where the lower surface 10b of the imaging plate 10 is lifted from the upper surface 21a of the guide plate 21, so that the lower surface 10b of the imaging plate 10 is not pressed or scratched.

  As the laminate film 15 is attached to the lower surface 10 b of the imaging plate 10, the laminate film 15 is pulled in the direction of being pulled out from the film roll 19. This tension force F3 is detected by the tension detector 47, and this tension detection signal is input to the controller 38.

  The control device 38 adjusts the electric power supplied to the drive motor 35 based on the tension detection signal, and adjusts the pulling force F1 of the laminate film 15 with the release paper 17 so that the laminate film 15 is not too tight and not too slack. . Thereby, the lower surface 10b of the imaging plate 10 is laminated without being wrinkled on the laminate film 15. Further, since the pulling force F2 is relatively stronger than the pulling force F1, the release paper 17 peeled off from the laminate film 15 is taken up by the release paper take-up roller 33.

  As shown in FIG. 6, when the laminate film 15 is adhered to the entire lower surface 10 b of the imaging plate 10 and the imaging plate 10 is completely separated from between the driving roller 25 and the driven roller 26, the driving roller 25 and the driven roller 26. The minimum distance d1 is formed again between the two and the rotation of the driven roller 26, but the conveyance of the imaging plate 10 is taken over by the conveyance roller pair 29.

  When the imaging plate 10 passes above the sensor 27, the sensor 27 detects this, and the cutter 28 is operated to cut the laminate film 15 protruding from the rear end of the imaging plate 10. As a result, the tensile force F3 becomes zero, and this is detected by the tension detection device 47, and this tension detection signal is input to the control device 38.

  The control device 38 restores the power supplied to the drive motor 35 to make the tensile force F1 of the laminate film 15 with the release paper 17 the same as the tensile force F2 of the release paper 17. Thereby, the laminate film 15 is not wastefully supplied toward the driven roller 26 side, and the laminate film 15 is not slackened.

  The imaging plate 10 to which the laminate film 15 is attached is conveyed to another finishing line, and then the excess laminate film 15 protruding from the front and rear ends is cut. Note that if an accident occurs where either the laminate film 15 or the release paper 17 suddenly cuts, the pulling force F1 changes abruptly. When the tension detecting device 47 detects this, the control device 38 stops the entire operation of the laminating device.

  In the embodiment described above, the tensile force F1 is weakened while being laminated on the imaging plate. Instead, the tensile force F2 may be increased while the tensile force F1 is kept as it is. Moreover, although the imaging plate is used as the flat plate member to be laminated, the present invention is not limited to this, and it is a matter of course that even a material having high rigidity or a material having low rigidity and flexibility can be used. Good. Moreover, in the said embodiment, although laminated on the lower surface of a flat member, you may laminate on the upper surface of a flat member.

  In the above embodiment, the thickness of the flat plate member (imaging plate) is 0.7 mm, and the minimum distance between the driving roller and the driven roller is 0.5 mm. However, the present invention is not limited to this, The minimum distance may be narrower than the thickness of the flat plate member. For example, the thickness of the flat plate member may be 1.0 mm and the minimum gap d1 may be 0.7 mm.

  Moreover, in the said embodiment, although the transparent resin film formed from PET was used as a laminate film, this invention is not limited to this, For example, you may use resin films, such as PVC and PEN, Instead of being transparent, for example, it may be colored blue.
