  An example of an embodiment of the present invention is shown in FIGS. FIG. 1 is a side view showing the configuration of the laminating apparatus 1, and FIG. 2 is a front view of the laminating apparatus 1.

  The laminating apparatus 1 has a gantry 3 provided with casters 2 so as to be movable, and frame members 4 are respectively provided on both sides of the gantry 3. On the right side of FIG. 1, there are provided locking means for placing the uncoated media roll 5 and a tension member 6 for applying a load to the roll 5 is provided.

  The tension member 6 is rotatably attached to a stay 7 provided between the frame members 4 and 4. A weight 8 is attached to a shaft portion provided upward, and the position of the weight 8 is determined. The load applied to the original media roll 5 can be adjusted by moving it up and down.

  The laminating liquid is applied to the medium M by the applying roller 10. A first pressing roller 11 and a second pressing roller 12 that form a conveyance path of the medium M are provided before and after the coating roller 10. The first pressing roller 11 and the second pressing roller 12 are pivotally supported at both ends by rotating frames 13, 13, and the rotating frames 13, 13 are rotatably attached to the frame member 4 by fulcrums 13 a, 13 a. It is attached.

  A liquid box 14 for holding a laminating liquid is provided below the coating roller 10, and the liquid box 14 is rotatably attached to the frame member 4 at a solid line position and a two-dot chain line position as shown in FIG. The levers 15 and 15 are movable, and the liquid box 14 is detachable.

  The laminating liquid in the laminating liquid tank 16 is supplied to the vicinity of the lower center of the paste box 14 by a pump 17. Then, recovery pipes 18 and 18 for determining the amount of laminating liquid retained in the liquid box 14 are provided in the vicinity of the left and right ends of the glue box 14, respectively. The laminating liquid overflowed from the recovery pipes 18 and 18 is configured to be returned to the laminating liquid tank 16.

  The laminating liquid has a lot of liquids that need to be circulated at all times to prevent drying, and has two paths: a path for supplying to the liquid box 14 and a path for returning to the laminating liquid tank 16.

  As shown in FIG. 1, the medium M on which the laminating liquid is applied by the application roller 10 forms a path that is conveyed obliquely upward, a section in which the laminating liquid application surface side is visible, a section that is transported for a certain section, and a heater 19. And a section cooled by the fan 20. A guide plate 21 for guiding the conveyance of the medium M is provided in the conveyance section. After cooling, the medium M is taken up by the take-up device 26.

  Next, the operation of the laminating apparatus 1 will be described. The media roll 5 for laminating is set at the original set position (FIG. 1). The media roll 5 is wound around a roll so that the printing surface is on the inside, and is drawn out so that the printing surface faces downward.

  Holding the turning handle 22, the rotating frames 13, 13 are rotated to the position of the two-dot chain line, and the pulled out medium M passes through the lower side of the first pressing roller 11 and the second pressing roller 12, and obliquely upward. Then, the paper is passed through the guide plate 21, the heater 19, and the fan 20, and attached to a winding paper tube (not shown) by an appropriate means such as a tape.

  The pump 17 is operated so that the laminating liquid in the laminating liquid tank 16 is supplied to the liquid box 14 and overflowed from the recovery pipe 18 so that the laminating liquid is circulated. The heater 19 and the fan 20 are also operated so that drying and cooling are performed.

  When the operation of the laminating apparatus 1 is ready, the rotation switch of the coating roller 10 is turned on, and the rotary frames 13 and 13 are lowered to the solid line position in FIG. With this operation, the medium M is pressed against the application roller 10 between the first pressing roller 11 and the second pressing roller 12, and the laminating liquid is applied to the medium M. In this state, the winding device 26 is operated to apply the laminating liquid to the medium M.

  When the media roll 5 is a medium printed by an ink jet printer, if it is wound with a large tension during printing, it will interfere with the feeding of the medium during printing. Often, the operation is to wind up the part. For this reason, it is not wound when the tension applied to the roll is too much. Therefore, the tension member 6 has a tension applying structure in which the media roll 5 is directly pressed. When the media roll 5 is installed, a stopper 23 that can be rotated and held at the two-dot chain line position may be appropriately disposed.

  By changing the height of the weight 8, it is possible to adjust the load applied to the media roll 5 and adjust the tension. As it is laminated, the diameter of the media roll 5 becomes smaller and thinner. Then, the tension member 6 is further inclined to the lower right side from the state of FIG. 1 and the weight 8 is also inclined to the right side. Therefore, the force pressed by the tension member 6 is reduced as the diameter of the raw roll 5 is reduced. growing. Therefore, the tension can be increased with respect to the tension that becomes lighter when unwinding as the diameter becomes smaller.

  Although the tension member 6 is not in contact with the printing surface side, a material that does not damage the medium M is appropriately used at the design stage for the portion in contact with the medium M. As with the medium M, the tension member 6 may be wide in the width direction, or may be an embodiment in which a plurality of members having a certain width are installed as appropriate.

  Next, the application roller 10 will be described. The coating roller 10 is made of stainless steel, and the surface thereof has a smooth cylindrical shape without any groove processing. The rotation of the coating roller 10 is driven by a drive source (not shown) such as a motor different from the conveyance of the medium M and can be adjusted by a speed adjustment volume (not shown).

  Since the surface of the application roller 10 has a smooth cylindrical shape, it is difficult to lift the surface of the application roller 10 from the liquid box 14 in order to apply the laminating liquid. Therefore, the application roller 10 is configured to rotate at a maximum peripheral speed of about 17 m / min.

  For example, when the medium M is wallpaper printed by an inkjet printer, the surface of the printed wallpaper is a rough surface with good hygroscopicity, or a smooth surface that is smooth and hygroscopic. There are two types of low media. There are also laminating liquids having high viscosity and low fluidity, and low viscosity and high fluidity laminating liquids. These laminating liquids are diluted with water as necessary.

  The medium M is pressed against the application roller 10 by the first pressing roller 11 and the second pressing roller 12 to form a transport path. At this time, the rotation frames 13 and 13 are configured such that the positions of the rotation frames 13 and 13 are regulated by the angle adjustment mechanisms 24 and 24, and the medium M formed by the first pressing roller 11 and the second pressing roller 12. The angle of the transport path can be changed. The rotating frame receiving portions 25, 25 of the angle adjusting mechanisms 24, 24 are configured to be able to adjust the receiving portions themselves by rotating them with screws.

  Since the application roller 10 has a smooth surface, the laminating liquid is applied to the medium M as shown in FIGS. 4 (a) and 4 (b) so as to rotate fast with respect to the conveyance speed of the medium M. A larger amount is raised from the liquid box 14 by the application roller 10, and a liquid pool of the laminating liquid is generated in the vicinity of the contact between the medium M and the application roller 10.

  If the medium M is low in hygroscopicity and the laminating liquid is high in fluidity, the conveyance path after application by the application roller 10 is adjusted to a conveyance path that is raised obliquely upward. If the conveyance path after application by the application roller 10 is kept at a horizontal level, the laminating liquid is applied more than necessary, and the laminating liquid flows during conveyance, causing unevenness. Therefore, the conveyance path of the medium M is adjusted by the angle adjustment mechanisms 24 and 24 so that the laminate M is not conveyed in a state in which more laminating liquid is applied.

  In particular, as shown in FIG. 4C, when the conveyance path after application by the application roller 10 is inclined downward, the medium M is removed from the liquid pool regardless of the hygroscopicity of the medium M or the fluidity of the laminating liquid. A drop of the laminating liquid is formed in the lower part of the media of the second presser roller 12, and a streaky pattern in which a large amount of the laminating liquid is applied appears clearly at the position where the drips are formed. It will end up. (See Fig. 4 (d))

  Also, if the medium M is highly hygroscopic and the laminating liquid is low in fluidity, a certain amount of laminating liquid is applied to the medium M in consideration of hygroscopicity in order to prevent unevenness. I have to do something. Therefore, in the case of high fluidity, the transport path after coating with the application roller 10 was set to a transport path that went up obliquely upward, but was adjusted to the transport path that went up diagonally at a slight angle from the horizontal direction or horizontal direction. However, there are no coating irregularities or bubbles on the surface of the laminate liquid.

  Since lamination is performed with various combinations of the conditions of the medium M and the laminating liquid as described above, in the apparatus of the present invention, the conveyance path of the medium M after application by the application roller 10 is conveyed obliquely upward from the horizontal direction. The angle can be adjusted in the path.

  The medium M on which the laminating liquid is applied is changed by the second pressing roller 12 in the upper right direction as illustrated in the conveyance direction. In this rightward upward transfer, the section in which the laminating liquid is transported so as to conform to the medium M, the section in which the laminating liquid is dried by the heater 19, and the medium M heated by being blown by the fan 20 are cooled. A section is provided. Each section is about 30 seconds, and the medium M is conveyed at a conveyance speed of about 40 to 50 cm / min. When heated with a heater immediately after the laminating liquid is applied, bubbles may be generated in the laminating liquid, and uniform coating and drying may not be possible. The transport route is used.

  The drying heater 19 is controlled by a thermocouple (not shown) and a temperature controller (not shown) so that the surface of the medium M coated with the laminating liquid is heated to 70 to 80 ° C. Three heaters 19 are installed so that they can be dried in the transport path. Of course, in the present invention, the number of heaters installed is not limited. What is necessary is just to install the heater of a required capacity | capacitance suitably.

  A reflector 27 or the like for reflecting the heat of the heater 19 to the medium side is appropriately provided above the heater 19, and the heater 19 and the reflector 27 can be changed so that the heating amount can be changed with respect to the laminating liquid that changes the coating amount depending on the type of the medium. If the position can be changed as appropriate, it is possible to improve the usability of the apparatus. In the present embodiment, the heater 19 and the reflection plate 27 can be changed so that the position of the heater 19 can be a distance from 30 mm (solid line position) to 120 mm (two-dot chain line position) with respect to the medium.

  When the media M is heated and taken up by the take-up device 26 with heat, the backing paper gets stuck on the surface coated with the laminating solution and is unraveled with the backing paper attached at the time of unraveling. Therefore, cooling is performed by blowing air with the fan 20 before winding. If the backing paper is peeled off, the printed surface may also be peeled off and damaged, so that the cooling section is very effective for a compact device for improving the finish. Further, if the angle of the fan 20 with respect to the medium M can be changed so that the air blow applied to the medium M can be adjusted, a user-friendly device can be obtained.

  Next, the winding device 26 is driven so as to wind up the medium M by a driving source such as a motor (not shown). The speed at which the medium M is wound can be adjusted to a desired winding speed by appropriately providing a speed adjustment volume in the operation unit 28.

  The medium M to be wound may be fixed by passing a paper tube through a winding shaft (not shown) or the like and attaching the medium M to the paper tube with a tape or the like as appropriate. Since the winding roll diameter increases as the winding amount increases, if the winding rotation is constant, the winding speed increases as the diameter increases, so winding can be performed at a constant speed. In order to be able to do this, the amount of rotation of the guide roller 29 is detected by a sensor and controlled to be wound at a set winding speed.

  The embodiment will be described with respect to the control of the winding speed. A slit plate 32 is provided at the shaft end of the guide roller 29, and a photomicrosensor 33 for reading the rotation of the slit plate 32, that is, the rotation of the guide roller 29 is installed. When the guide roller 29 is rotated by the amount of the medium M conveyed by 1 cm, a pulse signal that generates one pulse is generated by the slit plate 32 and the photomicrosensor 33. (See Figure 7)

  The operation unit 28 is configured so that the operator can input the thickness of the medium M to be coated in advance. Then, the number of pulse signals generated by conveying the medium M is coefficientd. If the paper tube installed in the winding device 26 has an inner diameter of 3 inches (outer diameter of 86.4 mm), for example, the product of the count value of the number of pulses and the thickness of the medium M becomes the area of the wound medium M. The diameter of the wound medium M can be calculated by obtaining the radius of a circle that is the total area of the product of the cross-sectional area of the tube, the count value of the number of pulses and the thickness of the medium M. If the diameter of the wound medium M can be calculated, it is possible to calculate how many rotations should be taken to achieve a predetermined transport speed. Therefore, the thickness of the medium M is input, and the unit length By counting the number of pulses generated for every 1 cm of conveyance, for example, every 1 cm, the apparatus can be configured at low cost without using expensive members such as servo control.

  In the control described above, the length of the medium M wound up is calculated by calculating the number of pulses. However, the number of pulses per unit time may be counted, and the winding speed may be controlled by increasing the count value.

  That is, if a paper tube having an inner diameter of, for example, 3 inches is used as in the above control, the winding speed of the coating apparatus is usually about 40 cm / min. Whether to rotate at the number of rotations can be calculated by 40 / (8.64 × π). At the beginning of winding, it is rotated at that rotational speed, and for example, a pulse is counted for one minute per unit time. If it is as said structure, since it is 1 pulse for every 1 cm conveyance, it will be 40 pulses, but since the winding diameter will increase a little, if the rotation speed is the same, the number of pulses will increase with time. Therefore, the count number measured for one minute and the count number measured for the next minute are stored in a memory or the like and compared in the control device. If the number of pulses increases by 10%, the winding speed is reduced by 10%. It is controlled to make it happen. By repeating this and controlling the number of rotations of winding so that the number of pulses measured for one minute is substantially constant, the number of pulses can be wound constant. With this control, it is possible to eliminate the need for input of thickness, so that the operation can be efficiently performed because the input is unnecessary.

  Also, instead of comparing the count value of the number of consecutive pulses per minute, the number of pulses measured for the first one minute is always stored, and compared with the count value of the subsequent one minute, the first one minute The pulse count for the first minute and the count value for the number of pulses per minute at which the subsequent winding becomes faster, such as a comparison between the number of pulses and the number of pulses for 2-3 minutes after the operation of the apparatus, As a comparison, the rotation speed may be controlled.

  Then, instead of 1 pulse in 1 cm transport, 1 pulse is generated in 5 mm transport and 1 pulse is generated in 2 mm transport, or the take-up speed is not reduced by 10% when the transport distance for one pulse is shortened or increased by 10%. If the parameters of the control are changed as appropriate, such as a 5% speed reduction for every 5% increase in the pulse, control with higher accuracy can be performed.

  In addition, the rotation control of winding may be performed by measuring the winding diameter of the medium M in the winding device 26 with a non-contact length measuring sensor without performing pulse measurement.

  In these embodiments, the laminating apparatus 1 may be configured to stop when the medium M having a predetermined length is wound up by detecting the rotation amount of the guide roller 29.

  In the laminating apparatus 1 described above, the transport path of the medium M is configured such that the transport path is formed without disposing a member such as a roller that contacts the surface on which the laminating liquid is applied. In order to prevent dust and the like from adhering to the surface on which the laminating liquid is applied, the rollers, guides, and the like that form the transport path are brought into contact with the side on which the laminating liquid is not applied.

  Then, the position of the vertex of the media roll 5 of the medium M on which the laminating liquid is applied is set higher than the vertex of the coating roller 10. That is, even if the diameter of the media roll 5 becomes smaller, the apex position is higher than the application roller 10 and the transport path is formed so as to be obliquely below the media roll 5. It is composed.

  With the above configuration, by providing the tension member 6 that directly applies a load to the media roll 5, the media M is taken up by the take-up device 26 with an appropriate tension applied. For this reason, during conveyance, the tension applied by the winding device 26 is applied to the media M, and there is no contact with the surface on which the laminating liquid is applied, and there is no contact with the laminating liquid. Is done.

  Next, another embodiment relating to the formation of the conveyance path after applying the laminating liquid with the application roller 10 will be described. In FIG. 1, the first pressing roller 11 and the second pressing roller 12 are installed on the rotating frame 13, the angle of the rotating frame 13 is changed at the fulcrum 13a, and the transport path of the medium M is adjusted. As described above, when the fulcrum 13a is disposed on the side of the medium original roll 5 with respect to the first pressing roller 11, the adjustment range is limited with respect to the range of angle adjustment.

  Therefore, as shown in FIGS. 5 and 6, the angle adjustment frame 30 is provided on the rotation frame 13, and the rotation fulcrum 30 a of the angle adjustment frame 30 is between the first pressing roller 11 and the second pressing roller 12. The configuration is located between them. The angle adjustment of the angle adjustment frame 30 is performed by angle fixing screws 31 provided on the rotating frames 13 on both sides. 13b is a stopper that contacts the second pressing roller 12 side of the angle adjusting frame 30 when the transport path of the medium M between the application roller 10 and the second pressing roller 12 becomes horizontal, and 13c is the maximum transport path. This is a stopper with which the first pressing roller 11 side of the angle adjustment frame 30 comes into contact when the angle (for example, 45 degrees) is reached.

  With the above configuration, the conveyance path can be adjusted and fixed to a desired angle by the angle fixing screw 31 within a range of 45 degrees from the horizontal. Since the first pressure roller 11 and the second pressure roller 12 are attached to the angle adjustment frame 30 so as to adjust the angle of the angle adjustment frame 30, the first pressure roller 11 and the second pressure roller 12 with respect to the application roller 10. Thus, the conveyance path can be easily adjusted while maintaining the parallelism.

Of course, the first pressing roller 11 and the second pressing roller 12 may be configured so that each of them can be independently adjusted with respect to the rotating frame 13, but in that case, the first pressing roller 11 and the second pressing roller 12 can be easily kept parallel to the application roller 10. It is necessary to be careful.
