Description

  The present invention relates to a laminating apparatus and a laminating method for forming a laminating layer on a recording surface of a recording medium on which an image is recorded.

  As a result of various improvements made to the recording apparatus (printer) and the recording medium, the recording system such as the ink jet recording system and the thermal transfer recording system can obtain an image quality comparable to a silver salt color photograph. In recent years, image information captured by a digital camera, digital video, scanner, or the like or electronic image information in a computer has been widely used as a technique for hard copying.

  In addition, in these recording methods, the recording surface of the recording medium is protected to give permanent durability, and the glossiness and smoothness of the recording surface are increased to further improve the image quality. For this purpose, a technique of laminating a laminate layer on a recording surface of a recording medium after image recording is also widely known.

  As an apparatus used for laminating on a recording surface, a recording medium and a laminating material which are laminated by supplying a laminating material comprising a base material and a laminating layer formed so as to be peelable on the base material onto the recording surface. There is a laminating apparatus that transfers the laminate layer onto the recording surface of the recording medium by thermocompression bonding, and then peels the substrate from the laminate layer (Patent Document 1).

  However, in the laminating apparatus disclosed in Patent Document 1, every time the recording medium is replaced with one having a different width size, the laminating material must be replaced with one having a suitable width size. However, in this case, an extra portion of the laminate layer (after the lamination process ( It is necessary to cut off a portion that is not laminated on the recording surface (non-laminated portion) along the edge of the recording medium, and in any case, it is complicated.

For this reason, there is a laminating apparatus that can save the labor of excising the non-laminate portion (Patent Document 2). FIG. 16 shows a schematic configuration of the laminating apparatus, in which a piece-like recording medium A cut to a predetermined feeding length and a laminating material B supplied as a continuous sheet from a roll are passed through a film guide roll F. It is laminated and heat-pressed when passing between the platen roll G and the heated intermediate roll H, and then the base material C is peeled from the laminate layer D by the peeling roll I arranged on the downstream side. However, in the laminating apparatus disclosed in Patent Document 2, when the substrate C is peeled off, the non-laminated portion Db is separated from the laminated portion Da. It is cut off and taken away with the base material C.

  By the way, any of the above laminating apparatuses performs pressure heating with a roller having a smooth surface. That is, the conventional laminating apparatus proposes only a glossy finishing laminating process for smoothing the surface of the laminating layer.

  Then, this invention makes it a subject to provide the laminating apparatus and the laminating method which can perform the laminating process rich in the variation.

  A first laminating apparatus according to the present invention is a laminating apparatus for forming a laminating layer on a recording surface of a recording medium. A laminating material in which a base material is peeled from the laminating layer is laminated on the recording medium. A first pressure-bonding portion that is thermocompression-bonded, a peeling portion that peels the substrate from the laminate layer of the heat-bonded laminate, and a second pressure-bonding portion that re-heat-bonds the substrate that has been peeled off The second pressure-bonding portion is characterized in that, among the pair of pressure-bonding means for generating a pressure-bonding action, a pressure-bonding means on the side acting on the laminate layer is one having an uneven working surface.

Further, the second laminating apparatus according to the present invention is a laminating apparatus for forming a laminating layer on the recording surface of the recording medium, wherein the base material is not laminated on the laminating layer and is larger in size than the recording medium. A pressure-bonding part that heats and pressure-bonds the laminate material so as to cover the recording medium , and transfers a portion of the laminate layer that protrudes from the recording medium to a transfer-receiving means disposed on the opposite side of the recording surface of the recording medium In order to separate the laminate portion where the laminate layer and the recording surface are in close contact with the non-laminate portion where the laminate layer and the transfer means are in close contact with each other, the transfer means is separated on the side opposite to the recording surface of the recording medium. and a separation unit, piezoelectric attaching portion, of the pair of crimping means for generating a crimping action as pressing means on the side acting on the laminate layer, there working surface is uneven Characterized by using the.

  The first laminating method according to the present invention is a laminating method in which a laminating layer is formed on a recording surface of a recording medium. A pair of pressure-bonding means that have an uneven working surface as a pressure-bonding means on the side that acts on the laminate layer after the substrate is peeled off from the laminated layer of the heat-bonded laminate material. Thus, the heat-pressure bonding is performed again on the substrate from which the substrate has been peeled off.

Further, the second laminating method according to the present invention is a laminating method for forming a laminating layer on the recording surface of the recording medium, wherein the base material is not laminated on the laminating layer, and the size is larger than that of the recording medium. overlapping of the laminate material so as to cover the recording medium, as pressing means on the side acting on the laminate layer by a pair of crimping means using what working surface is uneven, with thermocompression bonding, of the recording medium The portion of the laminate layer that protrudes from the recording medium is transferred to the transfer means disposed on the side opposite to the recording surface, and the laminate portion where the laminate layer and the recording surface are in close contact with each other and the laminate layer and the transfer means are in close contact In order to separate from the non-laminate portion, the transfer means is separated on the side opposite to the recording surface of the recording medium .

  According to the configuration of each of the above inventions, since the working surface of the pressure bonding means acting on the laminate layer is uneven, the surface pattern of the pressure bonding means is transferred to the laminate layer by thermocompression bonding, and the laminate layer The surface of the surface becomes uneven, resulting in a matte or silky laminate treatment with a semi-gloss finish or matte finish.

  In addition, according to the first laminating apparatus and the first laminating method, since the thermocompression bonding is performed not only once but a plurality of times, the adhesion of the laminate layer to the recording surface of the recording medium is increased. Become. Further, by increasing the adhesion, even if air is mixed between the recording medium and the laminate layer, it does not remain in the form of bubbles and is preferably removed.

Further, in the first laminating apparatus, the first pressure-bonding section is configured to heat and pressure-bond a laminate material having a size larger than the recording medium so as to cover the recording medium, and to record the recording surface of the recording medium. It is more preferable to transfer the laminate layer that protrudes from the recording medium to the transfer means arranged on the opposite surface side.

According to the above Ki構 formed by heat and pressure the laminated material having a size larger than the recording medium, a laminate layer of the laminate material is adapted to contact the entire surface of the recording surface of the recording medium, the recording surface The protruding portion is in close contact with the transfer target. In this state, when the transfer target is separated to the opposite side of the recording surface of the recording medium, the laminate layer is pulled (pulled) to the opposite side of the recording medium. In this case, since the tensile force acts intensively along the boundary between the portion where the recording medium is present and the portion where the recording medium is not present (that is, the edge of the recording medium), the laminate layer And a portion where the recording surface is pressure-bonded (laminate portion where the laminate layer is laminated on the recording surface) and a portion where the laminate layer and the transfer means are pressure-bonded (non-laminate portion which is not laminated on the recording medium) Cut Which is given of course, the edge of the laminate layer formed on the recording surface of the recording medium becomes clean along the edge of the recording medium.

In addition, the first laminating apparatus is provided with a transfer means for separating the laminate portion where the laminate layer and the recording surface are in close contact with the non-laminate portion where the laminate layer and the transfer means are in close contact from the viewpoint of automatic processing. Can be further provided to separate the recording medium on the side opposite to the recording surface of the recording medium.

  As described above, the present invention uses an uneven surface of the pressure-bonding means acting on the laminate layer, so that the surface of the laminate layer has an uneven semi-gloss finish or matte finish, Variations in laminating can be expanded.

  Hereinafter, a laminating apparatus according to an embodiment of the present invention will be described with reference to the drawings.

  First, an appearance image of the laminating apparatus according to the present embodiment will be briefly described with reference to FIGS. The laminating apparatus includes various functional units (which will be described later) in the housing 1, and a recording medium supply unit (supplying unit) that supplies the recording medium A for which image recording has been completed for laminating processing. 10 is provided on one side of the casing 1, and a finished product discharge section (discharge section) 150 that discharges the recording medium A that has been laminated is provided on the other side of the casing 1.

  The housing 1 includes side frames 1a and 1b arranged on the left and right sides, and a connecting frame 1c that is arranged at an appropriate position between the side frames 1a and 1b and connects the side frames 1a and 1b at a predetermined interval. Become. The side frames 1a and 1b are divided into upper and lower parts, respectively, and the upper side frame 1a and 1b and the connecting frame 1c for connecting the upper frame 1A constitute the upper casing 1A, while the lower side frame 1a and 1b. A lower housing 1B is configured by 1a, 1b and a connecting frame 1c connecting them.

  Therefore, the housing 1 can be separated vertically. More specifically, a part 1d of the upper housing 1A is rotatably supported by the lower housing 1B and swings so as to be openable and closable with respect to the lower housing 1B. A lock mechanism 2 is provided in the housing 1 in order to maintain a closed position where the upper housing 1A and the lower housing 1B are combined.

  The recording medium supply unit 10 includes a mounting plate 11 attached to a boundary portion between the upper housing 1A and the lower housing 1B on one side of the housing 1. On the other hand, the finished product discharger 150 also includes a mounting plate 151 attached to a boundary portion between the upper housing 1A and the lower housing 1B on the other side of the housing 1. The mounting plate 11 is rotatably attached to the upper housing 1A, and takes a horizontal position where the recording medium A can be mounted and a vertical position where the recording medium A cannot be mounted. The mounting plate 151 is fixedly attached to the lower housing 1B. It should be noted that a pair of width regulating guides that are relatively close to each other in the width direction is provided on the mounting plate 11 so that the center of the recording medium A is always aligned regardless of the width size of the recording medium A. preferable.

  The transport path of the recording medium A that connects the recording medium supply unit 10 and the finished product discharge unit 150 is the same as the placement plate 11 of the recording medium supply unit 10 and the placement plate 151 of the finished product discharge unit 150. It is set along the boundary between the upper casing 1A and the lower casing 1B. Therefore, the transport path is opened at the open position where the upper casing 1A is swung upward, and the recording medium A on the transport path can be taken out.

  As shown in FIG. 3 and FIG. 4, the functional unit is roughly divided from the recording surface (upper surface) side of the recording medium A conveyed on the conveyance path, and the base material C and the laminate layer as a base are laminated. A laminate material supply unit (supply unit) 20 that supplies the sheet-like laminate material B and a surface (lower surface: base surface) opposite to the recording surface of the recording medium A conveyed on the conveyance path are transferred. An under film supply unit (supply unit) 30 that supplies a sheet-like under film E as a means, and a laminate in which the recording medium A is supplied and stacked between the supplied laminate material B and the under film E ( First and second pressure-bonding parts (pressure-bonding parts) 40 and 50 for heat-pressing the recording medium A between the laminate material B and the under film E), and the laminate material B after the heat-pressure bonding Remove substrate C from Peeling part 60 for separating, base material collecting part (collecting part) 70 for collecting the peeled base material C, separating part 80 for separating the underfilm E after thermocompression bonding from the recording medium A, and the separated under The film E is divided into an under film collection unit (collection unit) 90 that collects the film E.

  As shown in FIG. 5, the laminate material supply unit 20 supplies the laminate material B as a continuous sheet from a roll, and includes a holder (laminate material holder) 21 that holds the roll of the laminate material B. 21 and a free roller 22 disposed between the conveyance path.

  Both ends of the holder 21 are rotatably supported by the side frames 1a and 1b together with the free roller 22. The free roller 22 is disposed so as to be on the inner side (conveying path side) of the roll attached to the holder 21 and the common tangent line of the roller 43 of the press-bonding section described later, thereby conveying the laminate material B fed from the roll. Wrapping is performed in a predetermined angle range in a predetermined section until reaching the path, and the approach angle of the laminate material B with respect to the transport path is determined. In addition, the free roller 22 is disposed in a region that can be affected by heat from the pressure roller 43 of the first pressure-bonding portion 40 serving as a heating roller, as will be described later. The material used for at least the surface of the free roller 22 is black alumite, which has a relatively excellent heat absorption rate and heat conductivity.

  A laminating material B used in the laminating apparatus of this embodiment includes a laminating layer D for laminating the recording surface of the recording medium A as shown in FIG. The laminate layer D has a laminated structure including an adhesive layer D ′ that adheres to the recording surface and a protective layer D ″ that is formed on the adhesive layer D ′ and protects the recording surface. The protective layer D ″ according to the present embodiment is formed of a transparent acrylic resin. The adhesive layer D ′ is laminated with the protective layer D ″ via a joint anchor coat layer D ″ ′ having transparency so as to maintain adhesiveness with the protective layer D ″. The adhesive layer D ′ has a higher adhesive force to the under film E than the adhesive force of the base material C to the protective layer D ″ and has permeability (in this embodiment, it is bonded by applying heat). A thermoplastic resin that exhibits strength: a polyester-based resin).

  Further, the laminate material B is a laminate layer (protective layer D ″) in order to prevent the laminate layer from being damaged during thermocompression bonding and transportation, and to prevent wrinkles and the like from being generated in the laminate layer during thermocompression bonding. A sheet-like base material C is laminated on D so as to be peelable. That is, by laminating the base material C on the laminate layer D, the laminate material B prevents the surface of the laminate layer D from being scratched and gives the laminate material B itself stiffness (thickening the thickness). The degree of freedom of bending in the laminate material B is reduced), and the occurrence of wrinkles in the laminate layer D due to the influence of pressure or the like during thermocompression bonding can be prevented. The base material C is composed of a film made of polyethylene terephthalate (PET), and is in close contact with the laminate layer (protective layer D ″) D so as to be peelable by its own adhesiveness. And a laminated structure.

  The laminate material B having the above configuration is larger in size than the recording medium A, that is, in a state where the laminate layer D is opposed to the recording surface of the recording medium A, the recording material is recorded with the laminate material B (laminate layer D). A size that can cover A is set. In the present embodiment, as described above, since the laminate material B is long, when the laminate material B covers the recording medium A in a state of protruding from both the vertical and horizontal directions of the recording medium A, the direction is conveyed (conveyance). The size of the travel direction in the path does not matter, and the width (the dimension in the direction orthogonal to the travel direction in the transport path) is set wider than the width of the recording medium A on the transport path. Therefore, the recording medium A does not protrude from the laminating material B in the width direction even when the recording medium A is parallel to the transport direction, or even when it is slightly inclined. The entire surface of the recording medium A can be reliably covered with the material B (laminate layer D). The roll of the laminate material B having the above configuration is wound so that the base material C faces the outside and the laminate layer D faces the inside, so that the base material C contacts the free roller 22. It is like that.

  On the other hand, returning to FIG. 5, the under film supply unit 30 supplies the under film E from the roll as a continuous sheet, and includes a holder (under film original fabric holder) 31 that holds the roll of the under film E, A free roller 32 is provided between the holder 31 and the conveyance path.

  Both ends of the holder 31 are rotatably supported by the side frames 1a and 1b together with the free roller 32. The free roller 32 conveys the under film E fed out from the roll by being arranged so as to be on the inner side (conveyance path side) of the roll attached to the holder 31 and the common tangent line of the roller 41 of the pressure-bonding section described later. Wrapping is performed in a predetermined angle range in a predetermined section until reaching the path, and an approach angle of the under film E with respect to the transport path is determined. In addition, the free roller 32 is disposed in a region that can be affected by heat from the drive roller 41 of the first pressure-bonding portion 40 that is a heating roller, as will be described later. The material used for at least the surface of the free roller 32 is black alumite, which has a relatively excellent heat absorption rate and heat conductivity, like the free roller 22.

  The under film E functions as a transfer material serving as a base in a laminated state, and is made of a material having thermal adhesiveness with the adhesive layer D ′ of the laminate material B or a material having the same quality as the adhesive layer D ′. A resin film is used. The under film E can employ either a single layer structure or a laminated structure, but in the present embodiment, a single layer film made of PET (polyethylene terephthalate) is employed. The under film E has a width size equal to or greater than that of the laminate material B so that the laminate material B (laminate layer D) does not protrude from the side edge of the under film E in a laminated state. Is used.

  The first pressure bonding unit 40 includes a drive roller 41 and a pressure roller 43. The driving roller 41 is disposed on the base surface side of the recording medium A, and the pressure roller 43 is disposed on the recording surface side of the recording medium A, and both ends thereof are rotatably supported by the side frames 1a and 1b. Has been. Between the rollers 41 and 43, the laminate material B, the under film E, and the recording medium A supplied from the recording medium supply unit 10 are laminated (hereinafter referred to as recording medium A, laminating material B (laminate material). B) and layers in which at least two of the under films E are laminated are collectively referred to as “laminated body”).

  Both rollers 41 and 43 generate a pressure-bonding action on the laminate (A + B + E). For example, the drive roller 41 is a metal roller or an ultra-thin rubber roller, and the pressure roller 43 is a silicon-based roller. The heat-resistant rubber roller is used.

  Further, both rollers 41 and 43 have heaters 42 and 44 at the shaft core portions and are heating rollers. The heating temperature on the surfaces of the rollers 41 and 43 is set in the range of 60 to 120 ° C. for the driving roller 41, and is set in the range of 80 to 120 ° C. for the pressure roller 43. The driving roller 41 is supplied from the under film supply unit 30 before the point (theoretical contact point between the rollers 41 and 43) where the recording medium A, the laminate material B, and the under film E are heat-pressed. The under film E is disposed so as to be wound at a predetermined angle so that the under film E can be preheated before reaching the thermocompression bonding point. Further, the pressure roller 43 is arranged so that the laminate material B supplied from the laminate material supply unit 20 is wound at a predetermined angle before the heat pressure point, and reaches the heat pressure point. It can be preheated prior to. In addition, since the free rollers 22 and 32 are heated by receiving heat from the rollers 41 and 43, they also have a function as a heating roller, and the laminating material B and the under film E preheat the rollers 41 and 43. Prior to this, the free rollers 22 and 32 are also preheated. In addition, the roller (driving roller) 41 on the under film E side in the first pressure-bonding part 40 is also set as a heating roller and lower than the heating temperature on the roller surface of the roller (pressure-bonding roller) 43 on the laminate material B side. This is to activate the heat-weldability between the laminate layer and the under film E while suppressing the thermal effect on the under film E.

  Further, the drive roller 41 cannot be displaced relative to the side frames 1a and 1b, whereas the pressure roller 43 is connected to the side frames 1a and 1b (and the drive roller 41) via the pressure force adjusting mechanism 45. On the other hand, relative displacement is possible. The crimping force adjusting mechanism 45 includes a base 450 attached to the side frames 1a and 1b, a shaft 451 attached to the base 450 and having an axis in a direction perpendicular to the conveyance path, and slides along the shaft 451. A movable body 452, an elastic body 453 that biases the movable body 452 toward the conveyance path, and a handle (adjusting member) 454 that adjusts the elastic restoring force of the elastic body 453. Usually, the pressure between the rollers 41 and 43 is set within a range of 50 to 120 kgf.

  As shown in FIG. 6, the second pressure bonding part 50 includes a driving roller 51 and a pressure roller 53. The drive roller 51 is disposed on the base surface side of the recording medium A, and the pressure roller 53 is disposed on the recording surface side of the recording medium A, and both ends thereof are rotatably supported by the side frames 1a and 1b. Has been. In the laminate (A + B + E), the base material C is peeled off at the peeling portion 60 located on the upstream side of the transport path from the second crimping portion 50, so that the laminate (A + B + E−) is between the rollers 51 and 53. C) is supplied.

  Both rollers 51 and 53 cause a pressure-bonding action to the laminated body (A + B + E-C). For example, a silicon-based heat-resistant rubber roller is used for both the driving roller 51 and the pressure roller 53. In addition, the pressure roller 53 is a roller whose surface is uneven such as matte or silky.

  Further, the pressure roller 53 has a heater 54 in the shaft core portion, and is a heating roller. The heating temperature on the roller surface is set within a range of 80 to 120 ° C. The drive roller 51 is not a heating roller. The heating temperature in the second press-bonding section 50 (heating temperature by the press-bonding roller 53) has a meaning in terms of finishing processing, and the heating temperature in the first press-bonding section 40 (total heating temperature in the driving roller 41 and the press-bonding roller 43). Set lower than. That is, for example, when bubbles are mixed between the recording medium A and the laminate layer D, if the pressure is applied without heating, the pressure is applied in a state where the adhesive layer D ′ of the laminate layer D is cured. Therefore, the air bubbles cannot be pushed in well, but when heated, the adhesive layer D ′ is softened, and the pressure is applied in that state, so that the air bubbles are pushed into the recording surface of the recording medium A from the gap of the ink. For the reason that the laminate layer D (adhesive layer D ′) is displaced from the recording surface of the recording medium A or peeled off when the heating temperature is too high, the second pressure-bonding portion 50 is removed. However, while heating, the heating temperature in the second crimping part 50 is set lower than the heating temperature in the first crimping part 40. Further, the reason why the driving roller 51 of the second pressure-bonding part 50 is not a heating roller is that the heating temperature in the second pressure-bonding part 50 is not excessively raised as described above, and the once heated laminate is heated again. If the temperature is too high, the quality of the recording medium A and the laminate layer D may be deteriorated, the heater is eliminated and the manufacturing cost is reduced, and the running cost is reduced by reducing the power consumption. In addition, the crimping force in the second crimping part 50 is set to be smaller than the crimping force in the first crimping part 40 due to the absence of the base material C.

  Similarly to the first pressure-bonding portion 40, the drive roller 51 cannot be displaced relative to the side frames 1a and 1b, whereas the pressure-bonding roller 53 is connected to the side frames 1a and 1b via the pressure-bonding force adjusting mechanism 55. Relative displacement with respect to 1b (and drive roller 41) is possible. Since the configuration of the crimping force adjusting mechanism 55 is the same as that of the crimping force adjusting mechanism 55 of the first crimping portion 40, no particular description will be given. Usually, the pressure-bonding force between the rollers 51 and 53 is set within a range of 50 to 120 kgf.

  The peeling part 60 is disposed between the first pressure bonding part 40 located on the upstream side of the conveyance path and the second pressure bonding part 50 located on the downstream side of the conveyance path with respect to the first pressure bonding part 40, and the conveyance path. Is provided with a knife edge (peeling guide body) 61 disposed to face the surface.

  That is, the peeling part 60 is a position at a predetermined distance downstream from the first pressure-bonding part 40 so as to separate the base material C from the laminate layer D after a predetermined time has elapsed since the first pressure-bonding part 40 is heat-bonded. Is provided with a knife edge 61. Thus, the peeling part 60 is disposed at a predetermined distance from the first pressure bonding part 40 because the laminate is activated (exhibits viscosity, etc.) by being heat-pressed by the first pressure bonding part 40. This is because an external force is applied to the laminate material B (laminate layer D) after the layer D reaches a normal equilibrium state (a state in which the adhesive force is increased).

  That is, when a predetermined time elapses from the heating in the first pressure bonding part 40, the adhesive force of the laminate layer D to the recording medium A is surely increased as compared with the adhesive force between the base material C and the laminate layer D. If the peeling process of the base material C is performed in the state, only the base material C is peeled cleanly without the laminate layer D being carelessly peeled off from the recording medium A, so that the distance between the peeling part 60 and the first pressure bonding part 40 is increased. Provided. Therefore, the interval (predetermined distance) between the peeling part 60 and the first pressure bonding part 40 is such that the time from passing through the first pressure bonding part 40 to reaching the peeling part 60 is approximately normal from the active state of the laminate layer D. It is set so that it substantially coincides with or exceeds the time (predetermined time) required to return to the equilibrium state.

  The knife edge 61 is held by the holder 62 so that the tip end portion thereof becomes the transport path side and is inclined at an acute angle with respect to the transport path. More specifically, the knife edge 61 is connected to the lower surface 61a facing the conveyance path in the peeling unit 60 and the downstream edge of the lower surface 61a in the conveyance direction so as to form an acute angle with the lower surface 61a. And an inclined surface 61b extending upward (extending toward the base material recovery unit 70). Further, a connecting line (ridge line) between the lower surface 61a and the inclined surface 61b extends in a direction substantially orthogonal to the transport direction of the recording medium A on the transport path.

  Further, the peeling portion 60 further includes a guide plate 63 having a guide surface facing the inclined surface 61b as a guide surface of the knife edge 61 with a predetermined distance, and a continuous sheet-like base peeled from the laminate layer D is provided. The material C is sent to the base material collection unit 70 through the inclined surface 61 b of the knife edge 61 and the guide surface of the guide plate 63.

  The base material collection unit 70 collects the continuous sheet-like base material C peeled off from the laminate layer D in a roll shape, and a holder (recovered base material holder) 71 that holds the roll of the base material C. Is provided. Both ends of the holder 71 are rotatably supported by the side frames 1a and 1b. Further, the holder 71 is disposed so that the winding surface is on the upstream side of the conveyance path with respect to the leading edge of the knife edge 61, whereby the substrate C to be peeled from the conveyance path is removed from the leading edge of the knife edge 61. In addition, the peeling angle of the base material C with respect to the conveyance path is determined.

  As shown in FIG. 7, the separation unit 80 is located downstream of the crimping unit (second crimping unit 50) in the transport path (more specifically, the second crimping unit 50 and the laminate (A + B-C: finished product)). And a knife edge (separation guide body) 81 disposed between the pair of transport rollers 100 for transporting the finished product to the finished product discharge section 150 and disposed facing the transport path.

  That is, the separation unit 80 places a predetermined distance downstream from the second pressure-bonding part 50 in order to separate the under film E from the recording medium A after a predetermined time has passed since the second pressure-bonding part 50 was heat-bonded. A knife edge 81 is provided at the position. Thus, the separation part 80 is disposed at a predetermined distance from the second pressure bonding part 50 because the laminate is activated (exhibits viscosity, etc.) by being heat-pressed by the second pressure bonding part 50. This is because an external force is applied to the laminate material B (laminate layer D) after the layer D reaches a normal equilibrium state (a state in which the adhesive force is increased).

  That is, when a predetermined time elapses from the heating in the second pressure bonding part 50, the adhesive force of the laminate layer D to the recording medium A is surely increased. Since the layer D is not inadvertently peeled off from the recording medium A, an interval between the separation unit 80 and the second pressure bonding unit 50 is provided. Accordingly, the interval (predetermined distance) between the separating portion 80 and the second crimping portion 50 is such that the time from passing through the second crimping portion 50 until reaching the separating portion 80 is approximately normal from the active state of the laminate layer D. It is set so that it substantially coincides with or exceeds the time (predetermined time) required to return to the equilibrium state.

  3 and 4, the distance from the second crimping part 50 to the separating part 80 is shorter than the distance from the first crimping part 40 to the peeling part 60. In addition to the heating temperature in the second crimping part 50 being set lower than the temperature, the laminate (A + B + E) passing on the transport path between the first crimping part 40 and the peeling part 60 is naturally cooled. On the other hand, between the second crimping part 50 and the separating part 80 (actually, across the upstream and downstream sides of the conveying path across the tip of the separating part 80 (knife edge 81)) A plate-shaped guide plate 83 is provided, which improves the transportability of the laminate (A + B + EC) and forcibly releases the heat of the laminate (A + B + EC) ( With forced cooling) This is because is functioning Te. And since the distance from the 2nd crimping | compression-bonding part 50 to the isolation | separation part 80 becomes short, size reduction of the whole apparatus can be achieved. In the present embodiment, the interval between the separation part 80 and the second pressure bonding part 50 is such that the time from passing through the second pressure bonding part 50 until reaching the separation part 80 is determined so that the laminate layer D is in the active state. Based on the correlation between the moving speed of the laminated body (A + B + E−C) on the conveyance path, the cooling efficiency of the guide plate 83, and the like so as to be the time (predetermined time) required to return to a substantially normal equilibrium state. Is set.

  Returning to FIG. 7, the knife edge 81 is held by the holder 82 so that the tip portion thereof becomes the transport path side and is inclined at an acute angle with respect to the transport path. Specifically, the knife edge 81 of the separation unit 80 is connected to the upper surface 81a facing the conveyance path in the separation unit 80 and the downstream edge of the upper surface 81a in the conveyance direction. And an inclined surface 81b extending downward to form an acute angle. In addition, a connecting line (ridge line) between the upper surface 81a and the inclined surface 81b extends in a direction substantially perpendicular to the transport direction in the transport path.

  In addition, the separating unit 80 includes the guide plate 83 that is built in the housing 1 in order to demarcate the conveyance path and has a shape straddling the upstream side and the downstream side of the conveyance path across the tip of the knife edge 81. . More specifically, the guide plate 83 has a distal end portion extending to the vicinity of the compression portion (second compression portion 50), and a base end portion of the guide plate 83 beyond the distal end portion of the knife edge 81 on the downstream side of the conveyance path. It is the shape extended to. Further, the separating unit 80 includes a guide plate 84 having a guide surface facing the inner surface (guide surface) of a portion of the guide plate 83 on the downstream side of the conveyance path from the tip of the knife edge 81 with a predetermined distance. Is further provided.

  Both guide plates 83 and 84 are bent at a predetermined angle in a direction in which a tip end portion (an end portion on the upstream side of the transport path) is separated from the transport path to form a tapered and widened inlet side opening. The guide plate 84 is offset in a direction away from the transport path with respect to the upper surface 81a of the knife edge 81, and is set at a lower position than the upper surface 81a of the knife edge 81. The guide surface interval is wider than the interval between the guide surface of the guide plate 83 and the upper surface 81 a of the knife edge 81. That is, the guide surface interval that defines the conveyance path on the downstream side of the knife edge 81 is set wider in the direction after separation than before the under film E is separated.

  The under film collection unit 90 collects a continuous sheet of the under film E, onto which the extra laminate layer D has been transferred, by rolling it into a roll. A holder for holding the roll of the under film E (collected under film holding body) 91 is provided. Both ends of the holder 91 are rotatably supported by the side frames 1a and 1b. Further, the holder 91 is disposed such that the winding surface is on the upstream side of the conveyance path with respect to the tip end (ridge line) of the knife edge 81, whereby the under film E separated from the conveyance path is removed from the knife edge 81. And the peeling angle of the base material C with respect to the conveyance path is determined.

  The configuration of each functional unit is as described above. Returning to FIGS. 1 to 4, the main components of the laminate material supply unit 20, the peeling unit 60, and the base material recovery unit 70 are the same housing (upper housing 1 </ b> A located on the recording surface side of the recording medium A). On the other hand, the main components of the under film supply unit 30, the separation unit 80, and the under film collection unit 90 are also arranged in the same casing (the lower casing 1B located on the base surface side of the recording medium A). ing. Moreover, the 1st crimping | compression-bonding part 40, the 2nd crimping | compression-bonding part 50, and the conveyance roller pair 100 are arrange | positioned ranging over both housings | casings (upper housing | casing 1A and lower housing | casing 1B).

  Further, the driving rollers 41, 51, 101 of the first pressure-bonding portion 40, the second pressure-bonding portion 50, and the conveying roller pair 100 are arranged in one housing (lower housing 1B), and are respectively pressure-bonding rollers (driven rollers). 43, 53, 102 are arranged in the other casing (upper casing 1A).

  Further, not only the first pressure-bonding portion 40, the second pressure-bonding portion 50, and the drive rollers 41, 51, 101 of the conveying roller pair 100 but also all of the holders 71, 91 of the base material collecting portion 70 and the under film collecting portion 90. , Sprockets, chains, gear trains, and other known driving force transmission means (see FIGS. 1 and 2; however, the number is not assigned since the configuration is clear from the drawings). It is to be transmitted. By these synchronous drives, the laminate material B is pulled from the laminate material supply unit 20, the under film E is pulled from the under film supply unit 30, and the laminate (A + B + E; A + B + E−C; A + B−C) is in the conveyance path. It is conveyed along the downstream side.

  However, in order to convey a thin film such as the laminate material B (laminate layer D thereof), the driving roller 51 of the second pressure bonding section 50 is overdriven by 3% or less than the driving roller 41 of the first pressure bonding section 40. Thus, a back tension is applied to the laminate material B between the compression portions 40 and 50. The reason why the content is 3% or less is that when the back tension is too small, a slack is generated between the first and second pressure-bonding portions 40 and 50, and the recording medium A is distorted or softened by heating. W is generated on the recording surface of the recording medium A. On the other hand, if the back tension is too large, the laminate layer D is extended by the back tension and vertical wrinkles are generated. This is because vertical wrinkles also appear on the recording surface of the recording medium A.

  The laminating apparatus according to this embodiment is configured as described above. Next, each step of the laminating process in the apparatus will be described.

  First, before performing the laminating process on the recording medium A, the laminating material B is pulled out from the laminating material supply unit 20 in advance, and the laminating material B is wound around the free roller 22 to be bonded to the first pressure bonding unit 40 (the driving roller 41 and the pressure bonding). Between the roller 43) and the second pressure bonding part 50 (between the driving roller 51 and the pressure roller 53), and the tip is wound around the holder 71 of the base material recovery part 70. Further, the under film E is pulled out from the under film supply unit 30, and the under film E is wound around the free roller 32, and the first pressure bonding unit 40 (between the driving roller 41 and the pressure roller 43) and the second pressure bonding unit 50 ( The tip portion is wound around the holder 91 of the under film collecting unit 90. In this state, the laminate material B and the under film E are overlapped on the conveyance path between the first crimping portion 40 and the separation portion 60.

  In this state, as shown in FIG. 5, the recording surface of the recording medium A is directed to the side to which the laminate material B is supplied (in this embodiment, the upper side corresponding to the arrangement of the laminate material supply unit 20), The recording medium A is sequentially supplied from the recording medium supply unit 10. That is, the laminating apparatus can continuously laminate a plurality of recording media A, with a gap between the preceding recording medium A and the succeeding recording medium A. The recording medium A is sequentially supplied from the recording medium supply unit 10. Then, each recording medium A that is sequentially supplied is in a state of being interposed between the laminating material B and the under film E with the recording surface and the laminating layer D facing each other. The recording medium A and the under film E are heat-pressed. Thus, since the laminate material B is supplied so as to protrude from both end edges in the conveyance direction and the width direction of the recording medium A, the laminate layer D softens and is recorded when it is heat-pressed by the first pressure-bonding portion 40. It is deformed so as to cover the recording surface and end surface of the medium.

  Then, as described above, since the laminate material B and the under film E are set to a size larger than the recording medium A, the recording medium A is sandwiched between the laminate material B and the under film E, and FIG. As shown in FIG. 2, the laminate layer D is transferred to the under film E so that the laminate layer D protrudes from the recording medium A, and the laminate portion Da is in close contact with the recording surface of the recording medium A, and the recording medium A of the laminate portion Da. Thus, a non-laminate portion Db in which the laminate layer D is in close contact with the under film E is formed.

  That is, as shown in FIG. 9B, the laminating material B, the recording medium A, and the under film E are heat-pressed at the first pressure bonding portion 40 (the three members of the laminating material B, the recording medium A, and the under film E). Pass through the first press-bonding portion 40), a recording medium A, a laminating portion B in which the laminating material B and the under film E are laminated, and a non-laminating portion Db in which the laminating material B and the under film E are laminated. A laminated body (A + B + E, B + E) is obtained. The transfer width Db of the laminate layer D transferred to the under film E is set to about 3 mm or more. If it is smaller than this value, the adhesive area between the under film E and the laminate layer D is small and the adhesive force is not sufficient, so the under film E and the laminate layer D may be peeled off. This is because the portion (laminate portion) Da where the layer D and the recording surface are pressure-bonded and the portion (non-laminate portion) Db where the laminate layer D and the under film E are pressure-bonded may not be separated cleanly.

  Next, the laminate (A + B + E, B + E) obtained in the first pressure bonding part 40 is conveyed to the peeling part 60 as shown in FIG. Since the laminate (A + B + E, B + E) is heated in the first pressure bonding part 40 and is in a state of being cooled to some extent as time (predetermined time) elapses, the adhesive layer D ′ of the laminate layer D is Curing has started (returning from the active state to the normal equilibrium state), and as a result, the adhesive layer D ′ has been substantially cured or has been cured to some extent (substantially normal equilibrium state) and has reached the peeling portion 60. In the laminate (A + B + E, B + E), the adhesion between the base material C and the laminate layer D is greater than the adhesion between the laminate layer D and the recording surface of the recording medium A and the adhesion between the laminate layer D and the under film E. (The adhesion force between the laminate layer D and the recording surface of the recording medium A and the adhesion force between the laminate layer D and the under film E are larger than the adhesion force between the substrate C and the laminate layer D). Therefore, even if the base material C is pulled upwards in the conveying direction via the knife edge 61, only the base material C is reliably peeled off, and one of the laminating layers D is as in the conventional laminating apparatus. Part or all is not taken away with the base material C.

  Moreover, in the peeling portion 60, the tip of the knife edge 61 is in sliding contact with the laminate (A + B + E), so that the laminate (A + B + E) is prevented from being lifted due to the peeling of the substrate C, and the substrate C is peeled off. The angle is stabilized.

  Next, the laminate (A + B + E-C) from which the substrate C has been peeled off at the peeling portion 60 is conveyed to the second pressure bonding portion 50 where the second thermocompression bonding is performed. As described above, the laminating apparatus according to the present embodiment employs a configuration in which the base material C is first heat-pressed in the presence of the base material C, and then the base material C is removed. The adhesion of the laminate layer D to the recording surface of the recording medium A can be improved, and even if, for example, bubbles are mixed between the recording medium A and the laminate layer D at the time of lamination at the first pressure-bonding portion 40. By removing these bubbles, a clean finished surface can be obtained.

  In addition, during the thermocompression bonding, the laminate layer D of the laminate material B (more precisely, the protective layer D ″ of the laminate layer D) is softened by heating. Therefore, since the surface of the roller 53 (pressing roller) on the protective layer D ″ side is a rugged surface such as matte or silky, the surface pattern of the roller 53 has a protective layer D ′ as shown in FIG. A laminate layer D that is transferred to the surface of ′ and has a semi-glossy or matte surface is formed.

  Next, the laminate (A + B + E-C) that has been heat-pressed for the second time in the second pressure bonding section 50 is conveyed to the separation section 80 as shown in FIG. In the laminate (A + B + E-C), the laminate layer D of the laminate material B is activated again by the thermocompression bonding at the second crimping portion 50, but the time after the thermocompression bonding at the second crimping portion 50 ( The adhesive layer D ′ of the laminate layer D is cured (returning from the active state to the normal equilibrium state) with the natural heat dissipation due to the elapse of a predetermined time and the forced cooling due to the heat dissipation action of the guide plate 83. Will move towards. As a result, the laminate (A + B + E-C) reaches the separation portion 80 in a state where the adhesive layer D ′ is substantially cured or cured to some extent (approximately normal equilibrium state), where the under film E is separated. Is done.

  Thus, the laminated body (A + B + E−C) having reached the separating portion 80 with the adhesive layer D ′ in a substantially normal equilibrium state moves downstream while sliding on the upper surface of the knife edge 81 of the separating portion 80. When passing through the ridgeline of the knife edge 81, the underfilm E is wound around the holder 91 of the underfilm collection unit 90 with the underfilm E being wound around the tip of the knife edge 81. At this time, as shown in FIG. 11, the recording medium A and the under film E move relative to each other so that the base surface of the recording medium A and the under film E are separated from each other. In other words, the recording medium A tends to move further between the guide plates 83 and 84 (conveyance path) toward the downstream side, whereas the under film E has a direction (that is different from the moving direction of the recording medium A). (The direction away from the base surface of the recording medium A). Therefore, since the laminate layer D of the non-laminate portion Db from which the substrate C has been peeled also tends to move in the same direction as the under film E, the boundary between the portion with the recording medium A and the portion without the recording medium A (that is, the non-laminate portion) The tensile force acts intensively at the boundary between Db and the laminate portion Da. As a result, only the non-laminate portion Db is surely cut away, and the edge of the laminate portion Da becomes clean along the edge of the recording medium A.

  One reason that the edge of the laminated portion is finished cleanly is considered to be that the edge of the recording medium A exhibits a function like a cutting blade. That is, the boundary between the laminated portion Da and the non-laminated portion Db is caused by the edge of the recording medium A due to the shearing force (when the under film E is separated, the reaction force of the edge of the recording medium A and The laminating layer Da and the non-laminating portion Db are covered with each other by the interaction of the adhesion of the non-laminating portion Db with the under film E due to the interaction between the laminating layer D and the non-laminating portion Db. It is cut along the edge of the recording medium A. In particular, since the knife edge 81 according to the present embodiment has an acute angle between the upper surface and the inclined surface, the under film collection unit 90 is determined from the moving direction of the under film E on the transport path and the tip (ridge line) of the knife edge 81. Since the moving direction of the under film E moving toward the head is an acute angle, it is considered that the edge of the recording medium A functions as a very sharp cutting blade.

  Alternatively, as another reason, as shown in FIG. 9B, due to the thickness of the recording medium A, the minimum width region of the laminate layer D along the edge of the recording medium A starts from the under film E. It is thought that it is in a slightly floating state. Since the pulling force when separating the under film E acts on the floating portion intensively, the laminate layer D is broken at the floating portion, and the laminated portion Da and the non-laminated portion Db are formed on the recording medium A. It is cut along the edge. Alternatively, as another reason, the laminate material B and the under film E which are set to a size larger than the recording medium A are used, and the laminate material B is bonded to the laminate material B by the crimping portions 40 and 50 with the recording medium A interposed. In order to thermocompression bond with the under film E, the laminate layer D of the laminate B is deformed along the shape of the recording surface and the edge of the recording medium A, and as a result, the edge of the recording medium A It is considered that the thickness of the minimum width region of the laminate layer D along the line is reduced. Since the pulling force when separating the under film E acts on the thinned portion intensively, the laminated layer D is broken at the thinned portion, and the laminated portion Da and the non-laminated portion Db become the recording medium. It is cut along the edge of A.

  As a matter of course, the laminate layer D of the non-laminate portion Db separated from the laminate portion Da is carried away together with the under film E.

  Further, in the separation unit 80, as shown in FIG. 7, guide surfaces (inner surfaces of the guide plates 83 and 84, which define the conveyance path across the upstream side and the downstream side of the conveyance path across the tip of the knife edge 81). Since the upper surface 81a) of the knife edge 81 is provided, even when the under film E is being separated, the laminate (A + B + E-C; A + B-C) can be stably conveyed along the conveyance path. As a result, fluttering in the normal direction of the laminate (A + B + E-C; A + B-C) can be suppressed, and the separation angle of the under film E can be stabilized. Further, when the under film E is pulled toward the under film collection unit 90, the leading portion of the recording medium A tries to follow the movement of the under film E in the initial stage, but the recording medium A is completely bent. Since the boundary between the laminated portion Da and the non-laminated portion Db is cut in a state where the posture can be restored by its own elasticity, the guide plate 84 disposed on the downstream side of the knife edge 81 is By configuring the knife edge 81 side to bend and expand the conveying path, the leading portion of the recording medium A is guided between the guide plates 83 and 84 (conveying path), and the recording medium A is on the downstream side. It is conveyed to the finished product discharge unit 150. Therefore, the finished product discharge section 150 has a clean edge along the edge of the recording medium A, and a laminate layer that is in close contact with the recording surface without air or the like being interposed between the recording medium A and the recording medium A. The recording medium A laminated in D is discharged.

  The present invention is not limited to any of the above-described embodiments, and various modifications can be made without departing from the gist of the present invention.

  For example, the above embodiment uses the recording medium A having a glossy recording surface (recording surface with high smoothness), but a semi-glossy or matte recording surface (uneven surface) such as a matte tone or a silky tone. It may have a certain recording surface.

  In the above-described embodiment, the under film E functions as a transfer target. However, as shown in FIG. 12, the under film supply unit 30, the under film collection unit 90, and the separation unit 80 are eliminated, and instead, crimping is performed. The roller (drive roller 41) of the portion (first pressure bonding portion 40) may be used as a transfer target, and the pressure bonding portion 40 may function as a separation portion that divides the laminated portion Da and the non-laminated portion Db. In this case, as shown in FIG. 13, when the outer peripheral surface of the drive roller 41 is separated from the base surface, the laminate portion Da in which the laminate layer D is in close contact with the recording surface of the recording medium A and the periphery of the recording medium A The protruding laminate layer D is pulled at the boundary with the non-laminate portion Db in close contact with the outer peripheral surface of the drive roller 41, and the boundary between the laminate portion Da and the non-laminate portion Db is clean along the edge of the recording medium A. Will be disconnected. However, when the driving roller 41 rotates with the extra laminating layer D (laminate layer D of the non-laminate portion Db) adhered on the outer peripheral surface of the driving roller 41, the laminating layer is reached each time it reaches the point where the laminating material B is pressure-bonded. Since D adheres and accumulates, in order to scrape and remove the residue of the laminate layer D adhering to the outer peripheral surface upstream from the point where the laminate material B is pressed against the recording medium A, It is preferable to provide a scraper (removing means) 85 whose tip is in contact with the outer peripheral surface of the drive roller 41 with a predetermined pressure.

  In the above-described embodiment, the first pressure-bonding part 40 and the second pressure-bonding part 50 are provided, and the thermocompression bonding is performed twice until the recording medium A is supplied and discharged. For example, as shown in FIGS. 14 and 15, a laminating apparatus including only one crimping portion 40 may be used. In this case, while using the laminate material B only of the laminate layer D without the substrate C, and using the uneven roller shown in FIG. Lamination processing that becomes semi-gloss or matte can be performed.

  Moreover, although the said embodiment uses the rollers 41, 43, 51, and 53 as a pair of crimping | compression-bonding means which produces a crimping | compression-bonding action, a flat press body may be sufficient, for example. In this case, the press body on the side that acts on the laminate layer D is prepared such that the inner surface (crimping surface) has irregularities such as a matte tone or a silky tone.

  In the above-described embodiment, the recording medium A recorded mainly by the ink jet recording method is a target of the lamination process. However, the recording medium may be a recording medium by other printing recording methods as well as the thermal transfer recording method. The recording medium made of a silver salt photograph is also targeted.

  In any of the above applications, the recording medium A having a glossy, semi-glossy or matte surface treatment is used. For example, in the case of an ink jet recording method, the ink amount when recording an image is used. By controlling the above, the recording surface of the recording medium A may be made uneven to be semi-glossy or matte.

  In the above-described embodiment, the recording surface of the recording medium A is a transport form in which the recording surface A is directed upward.

  Moreover, although the said embodiment uses the continuous sheet for the laminate material B and the under film E, it may be a cut sheet together with the recording medium A. When the laminate material B and the under film E are cut sheets, the laminate material supply unit 20 and the under film supply unit 30 are connected to the recording medium supply unit 10 regardless of whether they are supplied manually or automatically. Thus, it is necessary to change to a structure that can handle cut sheets.

  In the above embodiment, a long laminate material B having a width wider than that of the recording medium A is used so that the laminate material B protrudes from the length and width of the recording medium A. For example, the width of the recording medium A is A long laminate B having the same width as (the length in the direction orthogonal to the conveyance direction of the recording medium A (the direction in which the laminate material B is pulled out)) may be used.

  In the above-described embodiment, a long laminate material B wider than the recording medium A is used, and recording is performed so that there is a gap between the preceding recording medium A and the subsequent recording medium A. The medium A is sequentially supplied so that the laminate material B (laminate layer D) protrudes from the length and width (periphery) of the recording medium A. For example, a long laminate material B wider than the recording medium A is used. The recording medium A may be sequentially supplied so that the preceding recording medium A and the succeeding recording medium A are in close contact with each other.

  In the above-described embodiment, a long laminate material B wider than the recording medium A is used, and recording is performed so that there is a gap between the preceding recording medium A and the subsequent recording medium A. The medium A is sequentially supplied so that the laminate material B (laminate layer D) protrudes from the length and width (periphery) of the recording medium A. For example, a long laminate material B having the same width as the recording medium A is used. Alternatively, the recording medium A may be sequentially supplied so that the preceding recording medium A and the succeeding recording medium A are in close contact with each other. In other words, when the laminate material B (laminate layer D) is stacked on the recording medium A, the laminate material B (laminate layer D) may not protrude from the recording medium A.

  In the above embodiment, the separation part 80 of the under film E is arranged on the downstream side of the peeling part 60 of the base material C. However, the separation part 80 is arranged on the upstream side of the peeling part 60 and is still on the basis. The laminated portion Da and the non-laminated portion Db may be separated while the material C is attached, and then the base material C may be peeled off from the laminated layer D having only the laminated portion Da.

The substrate is not laminated on the laminate layer, and a laminate material larger in size than the recording medium is stacked so as to cover the recording medium, and the working surface is uneven as a pressure bonding means on the side that acts on the laminate layer. With a pair of pressure-bonding means using a certain one, heat-pressure bonding is performed , and the laminate layer protruding from the recording medium is transferred to the transfer-receiving means arranged on the side opposite to the recording surface of the recording medium,
In order to separate the laminate portion where the laminate layer and the recording surface are in close contact with the non-laminate portion where the laminate layer and the transfer means are in close contact with each other, the transfer means is separated on the side opposite to the recording surface of the recording medium. A characteristic laminating method.
