  In FIG. 1, the panel conveyance part 10 mounts the panel base material 1 which has the three-dimensional surface used as sheet sticking object, and conveys it in a horizontal direction. Above the panel conveying unit 10, a sheet winding unit 20, a sheet guide unit 30, an adhesive application unit 40, and a sheet pressing (lapping) rotating roller (hereinafter referred to as a soft) having a soft surface for sheet pressing. 50 and the like) are provided.

  The panel substrate 1 is a wood panel formed by processing a plate-like material made of, for example, MDF (medium fiber board), and a decorative sheet is wrapped on the outer surface thereof. It is used as a central panel portion of a decorative door having a frame-like collar on the peripheral edge. As shown in FIG. 2, the panel base material 1 of this example has a flat plate at the center, and the peripheral edge is formed so that the thickness is gradually thinner than the center. In other words, the panel base material 1 is integrally formed in a shape having step surfaces in the vicinity of the four peripheral edges of the plate-shaped material, and the outer surface of the plate-shaped material has a main surface portion (surface facing the thickness direction) 1a, The main surface portion has three continuous surfaces including left and right step surfaces (surfaces facing in the horizontal direction) 1b and upper and lower step surfaces (surfaces facing in the vertical direction) 1c.

  In addition, as shown in FIGS. 3A to 3C, the panel base material 1 of this example includes the step surfaces 1b and 1c in which the thickness of the peripheral edge portion changes gently only on one side of the panel base material. As shown in FIGS. 3D to 3F, there are cases where the both sides of the panel substrate have stepped surfaces 1b and 1c in which the thickness of the peripheral portion gradually changes. In addition, it is desirable to apply a primer in advance to the upper surface of the panel base material 1, at least the stepped surface portion, in order to cure the adhesive by reacting with the adhesive applied to the decorative sheet 2 as will be described later. The panel substrate 1 is not limited to the MDF as long as the stepped surfaces 1b and 1c are formed as described above, and other plywood, particle board, FRP or other plastics or metals such as aluminum are also used. can do.

  In the panel transport unit 10, a plurality of transport rollers 11 that rotate in the panel transport direction are provided intermittently along the transport direction, and a plurality of panel base materials 1 or sheets are pasted on the upper surface along the panel transport direction. The panel 1 ′ immediately after wearing is continuously moved in a state where it is placed.

  The sheet winding unit 20 is formed by continuously winding a long sheet 2 having a desired width. For example, the sheet winding unit 20 is provided above the panel conveyance unit 10 in a direction orthogonal to the panel conveyance direction. The sheet 2 can selectively use vinyl chloride resin, olefin, paper, or the like, and may be printed with a pattern such as wood grain.

  The sheet guide unit 30 is configured such that a plurality of guide rollers 31 are provided in a direction orthogonal to the panel conveyance direction, and guides the sheet 2 drawn from the sheet winding unit 20 to the panel conveyance unit 10.

  The adhesive application unit 40 applies an adhesive to one side (back surface) of the sheet 2 in the process in which the sheet 2 drawn from the sheet winding unit 20 is guided to the panel conveyance unit 10. As the adhesive, a solvent system, an aqueous system, a hot melt system, or the like can be selectively used.

  As the adhesive application unit 40, a knife coater, a roll coater, or the like can be used. The knife coater feeds an adhesive from an adhesive supply unit to a container for storing an adhesive, and a pair of knife-shaped metal plates is disposed in the direction perpendicular to the sheet running direction in the vicinity of the container. The adhesive flowing out from the gap between the plates is applied to the back surface of the sheet. At this time, it is possible to control the amount of adhesive applied to the sheet by applying an agent that adjusts the gap between the pair of metal plates to adjust the amount of adhesive flowing out.

  Further, the roll coater sends an adhesive from an adhesive supply unit to a container storing the adhesive, and an adhesive application roller that is rotatable around a horizontal axis in a direction perpendicular to the sheet running direction is provided in the vicinity of the container. It arrange | positions, it is comprised so that a part of adhesive application roller may be immersed in the adhesive agent in a container, and another part of application roller may be made to touch a sheet | seat back surface. At this time, it is possible to control the amount of adhesive applied to the sheet by finely adjusting the positional relationship between the coating roller and the sheet.

  For example, as shown in FIG. 4, the soft roller 50 is formed in a cylindrical shape (or a columnar shape) having a rotating shaft core portion, and is arranged along a direction orthogonal to the panel conveying direction, and is rotatably held. And has a predetermined soft surface that is softer than the panel substrate 1 and the sheet 2. As shown in FIG. 5 (b) or FIG. 6 (b), the soft roller 50 has a minimum position on the soft surface in a state where the panel substrate in the transported state does not exist below (the state where it does not contact the upper surface of the panel substrate). It is held at a height position that is slightly lower than the stepped surface position of the panel base material in a state where the panel base material 1 in a transported state exists below (in contact with the upper surface of the panel base material). Thereby, as shown in FIG. 5A or 6A, in the state where the soft surface of the soft roller 50 is in contact with the upper surface of the panel base material, the roller surface of the contact portion is shallower than the thickness of the panel base material 1. It will be dented within the range, and will be in the state which pressed the whole surface on the panel base material of a conveyance state. In this case, the roller surface portion in contact with the upper surface of the central portion of the panel substrate 1 is recessed deeper than the roller surface portion in contact with the stepped surface of the panel substrate 1, and the degree of the recess is the softness of the soft roller surface. Depends on gender.

  Therefore, the soft roller 50 contacts the sheet on which the adhesive is applied to the entire lower surface of the transported panel base material in a pressed state and continuously rotates the back surface of the sheet ( The adhesive application surface) is superposed on the upper surface of the panel base material so as to adhere to and adhere to the upper surface of the panel.

  Further, as shown in FIG. 1, a roller surface temperature control unit 51 for controlling the soft surface temperature of the soft roller 50 is provided. The roller surface temperature control unit 51 controls the heating temperature of the soft roller heating means 52, the temperature setting means (not shown), the soft roller soft surface temperature sensor (not shown), and the soft roller heating means 52. A heating temperature control means (not shown), and by controlling the soft surface temperature of the soft roller 50 to an appropriate predetermined value, the adhesion of the sheet 2 to the upper surface of the panel substrate is improved. It becomes possible.

  An example of the soft roller heating means 52 is configured such that a heat source (for example, a heater) is disposed in the vicinity of the soft roller 50 along the roller length direction, and the soft surface of the soft roller 50 is heated from the heat source. However, a heat source may be incorporated in the soft roller 50. An example of the soft roller soft surface temperature sensor can be configured such that a temperature detector (sensor) is in direct contact with the soft surface of the soft roller 50.

  The soft roller 50 may be made of natural rubber, synthetic rubber, urethane rubber, silicone rubber or the like having a desired softness as a whole or on the surface. When silicone rubber is used, desired softness and desired heat resistance against heating can be easily obtained, and even if the adhesive applied to the sheet 2 adheres (transfers), it can be easily peeled off. is there.

  Further, an adhesive application amount control unit (not shown) for controlling the amount of adhesive applied to one side of the sheet 2 by the adhesive application unit 40, and the adhesive was applied as shown in FIG. It is desirable to provide a sheet temperature control unit 41 for controlling the temperature of the sheet 2 in the state and controlling the degree of drying of the adhesive. As a result, the amount of adhesive applied is appropriately controlled according to the material of the sheet 2 (resin sheet, printing paper, etc.), and the temperature of the sheet with the adhesive applied and the degree of drying of the adhesive are appropriately controlled. can do. In particular, even when a paper-type decorative sheet with little expansion and contraction is used, the sheet can be easily stuck without curling while preventing curling of the sheet.

  In order to enhance the sheet pressing action by the soft roller 50, for example, as shown in FIGS. 5 (a) and 5 (b), a floor plate 12 having a size slightly larger than the panel substrate 1 on the conveying roller 11 and It is desirable to place the panel base material 1 through cushion materials (for example, sponges) in order.

  Furthermore, when lapping a three-dimensional panel base material provided with step surfaces in the vicinity of the four peripheral edges on both sides, as shown in FIGS. 6 (a) and 6 (b), the panel base material 1 in the transported state is shown. It is desirable that at least the lower part in the vicinity of the peripheral edge on the front end side and the rear end side in the transport direction is placed on the floor plate 12 via the support member 14. As a result, when the sheet is pressed by the soft roller 50, the vicinity of the front end side periphery and the rear end side periphery in the panel conveying direction can be reinforced, and the panel base material 1 can be prevented from rattling, flapping, rebounding, and the like. Become. In addition, it is desirable to dispose a pressing member in the vicinity of the soft roller 50 that presses at least a part of the upper surface of the panel immediately after adhering the sheet on the downstream side in the panel conveying direction from above. As this pressing member, it is desirable to provide a pressing member that does not damage even if it comes into contact with the upper surface of the panel, for example, a pressing roller.

(Sheet sticking method)
Next, an example of the sheet sticking method of this invention is demonstrated, referring drawings. As shown in any of FIGS. 3 (a) to 3 (c), a plurality of panel base materials 1 provided with outward step surfaces on the four peripheral edges on one side are shown in FIGS. 5 (a) and 5 (b). As shown in the drawing, each step surface is placed and transported on the panel transport unit 10 so that the stepped surface is in an upward state. On the other hand, an adhesive is applied to the back surface of the sheet 2 drawn out from the sheet winding unit 20, and the soft surface temperature of the soft roller 50 that is rotatably arranged above the sheet bonding position is controlled. The coated sheet 2 is pressed against the entire surface of the transported panel substrate by the soft roller 50.

  At this time, first, the front end portion of the adhesive-coated surface of the sheet 2 coated with the adhesive is aligned with the front end portion in the transport direction on the panel base material or the front position thereof, and then the panel transport portion 10 is driven to drive the panel base. If the material 1 is conveyed, the soft roller 50 rotates as the panel base material 1 moves on the conveyance unit 10.

  As a result, the soft roller 50 presses the sheet 2, and the adhesive application surface of the sheet 2 is automatically and continuously superimposed on the upper surface of the transported panel base material 1, and the adhesive application surface of the sheet 2 is Adhered to the top surface of the material. At this time, since the soft roller 50 has a predetermined soft surface, even when the weight of the soft roller 50 is added to the boundary portion between the main surface portion 1a and the stepped surface portion of the panel base material 1, No wrinkles or horizontal streaks in the direction perpendicular to the panel conveying direction are generated on the sheet 2.

  Thus, in a state where the sheet 2 is bonded to the upper surface of the panel substrate 1, for example, an operator cuts the sheet 2 along the outer peripheral edge of the panel using a cutter for each panel that has been bonded. . Therefore, the operator can perform sheet sticking work easily and in a short time without having a high degree of skill, and the labor of the transport work is reduced, so that the efficiency of the sticking process is improved and the manufacturing is performed. Cost can be reduced.

  That is, according to the sheet sticking method and the sheet sticking apparatus described above, wrinkles are not generated on the outer surface of the three-dimensional panel substrate 1 by using the soft roller 50 having a predetermined soft surface. Thus, it can be applied easily and efficiently, and the production efficiency is high and can be realized at a relatively low cost. By appropriately controlling the surface temperature of the soft roller 50, wrinkles are not generated at the ridges at the four corners where the step surface of the lateral peripheral edge and the step surface of the vertical peripheral edge intersect the flat central portion. It becomes possible to stick the sheet | seat 2 to.

  Also, depending on the sheet material such as a resin sheet or printing paper, the amount of the adhesive applied to the back surface of the sheet 2, the temperature of the sheet 2 in the state where the adhesive is applied, and the degree of drying of the adhesive are appropriately set. By controlling, curling of a paper sheet having low stretchability can be easily performed while curling.

  6 (a) and 6 (b) with respect to the panel substrate 1 provided with stepped surfaces in the vicinity of the four peripheral edges on both sides as shown in any of FIGS. 3 (d) to 3 (f). When sticking the sheet 2 as shown in Fig. 1, first, the sheet 2 is stuck on one side of the panel base material as described above, and then the panel is reversed and the sheet 2 is stuck on the other side of the panel. .

<Second Embodiment>

It is necessary to configure the soft roller 50 so as to have a soft surface wider than the panel substrate 1 so that the soft surface can come into contact. On the other hand, when the outward stepped surface is provided only in the vicinity of the peripheral edge along the transport direction among the four peripheral edges of the panel base material 1, the soft surface of the soft roller 50 comes into contact with the stepped surface. As described above, the soft roller 50 may be configured to have a soft surface at least in a portion corresponding to the vicinity of the step surface of the panel base material 1.

  Hereinafter, as shown in any of FIGS. 3D to 3F, the sheet sticking shown in FIG. 1 is applied to the panel base material 1 provided with stepped surfaces in the vicinity of the four peripheral edges on both sides. The Example which sticks a sheet | seat using an apparatus is demonstrated.

As the decorative sheet 2 to be wrapped on the panel substrate 1, an olefin resin sheet having a sheet width of about 500 to 600 mm and a thickness of 0.1 to 0.5 mm before sticking is used.

  The adhesive applied to one side of the decorative sheet 2 is for water-based wrapping, the coating thickness is about 0.1 mm, and the temperature of the sheet just before sticking is controlled to about 30 to 70 ° C. As the soft roller 50 for pressing the sheet, cylindrical silicone rubber is used, the outer diameter is about 200 to 300 mm, the length is about 500 to 1200 mm, and the surface is softer and softer than the olefin resin sheet or MDF. The surface temperature is controlled at about 150-250 ° C. The soft roller 50 is positioned at a position where the lowest position of the soft surface in the state where the transported panel base material does not exist is lower than the stepped surface placement of the panel base material in the state where the transported panel exists below.
