Description

  The present invention relates to a method for manufacturing a door panel.

  Conventionally, on the front part of the kitchen cabinet 20 provided with the sink 21 and the heating cooker 22, for example, as disclosed in Patent Document 1, a user can perform comfortable kitchen work with a natural standing posture with a knee bent appropriately. In order to be able to do so, it has been proposed to provide a clearance space 23 that is recessed backwards leaving the upper part of the front part (see FIG. 3). The front panel of the kitchen cabinet 20 is provided with the door panel 1 that opens and closes the storage space 24 inside the kitchen cabinet. When the escape space 23 is provided as described above, the front panel of the door panel 1 has an upper portion thereof. In order to leave the area and form the escape space 23, the pull-in portion 11 that is pulled backward is provided. That is, the front protrusion part which protrudes ahead compared with the site | part in which the drawing-in part 11 was formed in the upper area of the door panel 1 is formed.

  By the way, the kitchen work uses cooking utensils such as pots and water and oil, so the surface of the door panel 1 exposed on the front surface of the kitchen cabinet 20 may accidentally hit with water or oil or the cooking utensils. Therefore, the decorative layer 9 is not formed on the surface of the door panel 1 (the surface of the base material 2) but on the back surface of the base material 2 made of a transparent resin. It is preferable to make the decorative layer 9 appear in appearance through the base material 2 in such a case, but in such a case, the base material 2 has a substantially uniform front-rear thickness in order to make the appearance of the decorative layer 9 substantially uniform. Formed. Thus, when the door panel 1 is provided with the lead-in portion 11 or the front protrusion as described above, the base 2 is recessed from the back side as a front protrusion at the end 2a (upper end region). A bent portion 4 protruding to the surface side is formed (see FIG. 4).

  Here, the door panel 1 is usually colored or painted to enhance its appearance. The decorative material 9 is applied to the base plate 2 by applying a paint to the base material 2. It is generally done by forming, but especially when applying a complicated makeup such as a pattern or a pattern, a decorative sheet 3 formed by printing a pattern is attached to the base material 2. Then, the decorative layer 9 is formed (see, for example, Patent Document 2).

  For attaching the decorative sheet 3 to the base material 2, first, the base material 2 and the decorative sheet 3 are set facing each other in the laminating space 6 of the vacuum laminating apparatus 5. Here, according to the set decorative sheet 3, the laminating space 6 is divided into two, but the base material 2 is arranged in the one laminating space 6 divided into two. In addition, the space on the side where the base material 2 is arranged in the divided lamination processing space 6 is referred to as a base material arrangement side space 6a, and the space on the side where the base material 2 is not arranged is referred to as a non-base material arrangement side space 6b. . Next, the lamination processing space 6 (the base material placement side space 6a and the non-base material placement side space 6b) is evacuated, and then the non-base material placement side space 6b is pressurized to form the base material placement side space 6a and the non-base material. It is carried out using a vacuum laminating method in which the decorative sheet 3 is stuck along the base material 2 by generating a pressure difference with the material arrangement side space 6b.

  In this vacuum laminating method, the decorative sheet 3 can be adhered to the flat substrate 2 as described in Patent Document 2, but as described above, When the decorative sheet 3 is to be attached to the back surface of the transparent base material 2 in which the bent portion 4 that is recessed from the back surface side and protrudes to the front surface side is formed on the end portion 2a, the bent portion 4, the decorative sheet 3 may not be attached along the concave back surface, and there is a high risk of product failure.

In particular, as shown in FIG. 7, the base material 2 is laminated so that the bent portion 4 is positioned corresponding to the peripheral portion 3b of the sheet surface of the decorative sheet 3 held by the vacuum laminating apparatus 5 and having little room for deformation. When placed in the space 6, if the vacuum laminating process is performed in the laminating space 6 in this state, the decorative sheet 3 comes close to the base material 2 from the central portion 3a of the sheet surface having a relatively large room for deformation (dotted line). ), The decorative sheet 3 is gradually attached from the central portion of the substrate 2 toward the end 2a. Here, although the peripheral part 3b of the sheet | seat surface of the decorating sheet 3 will be affixed on the concave back surface of the bending part 4 of the edge part 2a of the base material 2, of the sheet | seat surface of this decorating sheet 3 The peripheral portion 3b is originally held by the vacuum laminating apparatus 5 so that there is little room for deformation, and since the central portion 3a of the sheet surface is attached to the base material 2 as described above, the peripheral portion 3b is also deformed by this. In other words, it is extremely difficult to attach the peripheral edge portion 3b of the sheet surface of the decorative sheet 3 along the concave back surface of the bent portion 4 of the base material 2, resulting in production failure. The fear of was particularly high.
JP 2006-122565 A Japanese Patent Application Laid-Open No. 11-207877

  The present invention has been made in view of the above points. The object of the present invention is to provide a back surface of a transparent base material having a bent portion that is recessed from the back surface side and protrudes to the front surface side. It is an object of the present invention to provide a method for manufacturing a door panel that can be securely attached along a decorative sheet.

  In order to solve the above problem, in the door panel manufacturing method according to claim 1, the decorative sheet 3 with a pattern is held by the vacuum laminator 5 at the periphery of the sheet surface. A transparent base material 2 of the door panel 1 which is arranged in the laminating processing space 6 so as to divide this space into two, and is formed with a bent portion 4 which is recessed from the back surface side and protrudes to the front surface side at the end portion 2a. Is placed in one space 6a of the bisected laminating space 6 so that the back surface thereof faces the surface of the decorative sheet 3, and the laminating space 6 is evacuated or the laminating space 6 is evacuated. After pulling, the pressing means 25 provided in the vacuum laminating apparatus 5 presses the sheet surface of the decorative sheet 3 facing the bent portion 4 of the base material 2 toward the back surface of the bent portion 4, thereby laminating processing space The decorative sheet 3 includes the bent portion 4 of the base material 2 so that a pressure difference is generated between the two divided spaces 6a and 6b of the laminating space 6 by pressurizing the other space 6b. It sticks along the back surface of the material 2, It is characterized by the above-mentioned.

  According to this, the sticking process to the base material 2 of the decorative sheet 3 (the pressure difference between the two divided spaces 6a and 6b of the laminating space 6 by pressurizing the other space 6b of the laminating space 6) Before the step of causing the decorative sheet 3 to be pressed by the pressing means 25 so that the decorative sheet 3 is brought close to the concave back surface of the bent portion 4 of the base material 2. It can be attached to the concave back surface of the bent portion 4 (at a timing earlier than the portion), and the decorative sheet 3 can be reliably attached to the back surface of the substrate 2 including the bent portion 4.

  In the present invention, it is possible to reliably adhere the decorative sheet along the back surface of the transparent base material in which the bent portion that is recessed from the back surface side and protrudes to the front surface side is formed at the end portion. It has the advantage that it can.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. The door panel 1 of this example is the door panel 1 for kitchen cabinets arrange | positioned at the front surface of the kitchen cabinet 20 so that opening and closing is possible like FIG. The front part of the kitchen cabinet 20 has a relief space 23 that is recessed backwards leaving the upper part of the front part so that the user can perform comfortable kitchen work in a natural standing posture with the knees bent appropriately. The front panel of the door panel 1 of this example is provided with a lead-in part 11 that is pulled back to form a clearance space 23 while leaving the upper area.

  Specifically, as shown in FIG. 3C, the door panel 1 of this example is formed by attaching a back plate 7 to the back side of the base material 2 via a gap and filling the gap with the core material 8. . For example, ABS resin is used for the back plate 7, and foamed urethane resin is used for the core material 8. The base material 2 is an injection-molded product made of a transparent resin such as an acrylic resin. Specifically, as shown in FIG. 4, the flange wall portion 13 extends rearward from the peripheral edge of the vertical wall portion 12 serving as the front portion of the door. It is formed in the container shape which protruded. A notch 14 is formed in the center portion in the width direction of the flange wall portion 13a on the upper surface.

  As described above, the front portion of the door panel 1 of the present example is provided with a pull-in portion 11 that is pulled backward to leave the upper region and form a clearance space 23. In the base material 2 of the door panel 1, as shown in FIG. 4, a bent portion that is recessed from the back surface side and protrudes to the front surface side so as to correspond to the upper region of the base material 2 that does not constitute the pull-in portion 11. 4 is formed, and the portion constituting the lead-in portion 11 is formed in a planar shape so as to be located behind the bent portion 4. That is, the base material 2 is formed in a shape in which the bent portion 4 is formed only at one end portion 2a (upper region). Specifically, the bent portion 4 of the present example is bent so that the vertical wall portion 12 of the base material 2 protrudes gently forward from the drawing-in portion 11, and from the frontmost position of the vertical wall portion 12. The flange wall portion 13a on the upper surface is formed so as to protrude rearward, and the angle between the vertical wall portion 12 and the rear surface side of the flange wall portion 13 is formed in an acute angle shape. That is, the concave bent portion 4 as viewed from the back side is formed in a shape having the deepest portion at the upper end of the substrate 2.

  In addition, the base material 2 constituting the front portion of the door panel 1 is formed with a grip portion 19 for gripping the door panel 1 at the center in the width direction. Specifically, the gripping portion 19 is configured by a digging recess 15 formed by digging a part of the bent portion 4 in the vertical wall portion 12 so that the flat lead-in portion 11 is continuous upward. Yes. In other words, the digging recess 15 is formed as a portion protruding backward from the concave back surface of the bent portion 4 when the base material 2 is viewed from the back surface side. More specifically, an opening 16 is formed in the upper surface portion of the dug recess 15. When the door panel 1 is shipped, the opening 16 is closed by a finger hook fitting (not shown).

  As shown in FIG. 2, the door panel 1 of this example has a decorative layer 9 formed on the back surface of the transparent base material 2, and the makeup of the decorative layer 9 passes through the transparent base material 2 to the front surface of the door panel 1 (that is, It appears on the front of the kitchen cabinet 20). Since kitchen work uses cooking utensils such as pans and water and oil, there is a risk of water and oil adhering to the front of the door panel 1 exposed on the front of the kitchen cabinet 20 and accidentally hitting the cooking utensils. However, as described above, the decorative layer 9 is not exposed on the front surface of the door panel 1, and the front surface of the door panel 1 is formed by the surface of the base material 2, so that the decorative layer 9 is protected. .

  Here, the decorative layer 9 of this example is formed by the decorative sheet 3 formed by printing an arbitrary pattern or design. As shown in FIG. 2 (b), the decorative sheet 3 is formed by laminating a decorative layer 32 printed with acrylic urethane printing ink on the surface side of a protective layer 31 made of PET (polyethylene terephthalate). It is constituted by laminating an adhesive layer 33 made of an acrylic adhesive material on the surface side of 32. When the base material 2 has the bent portion 4 formed at the end 2a (upper region) as described above, in a normal vacuum laminate manufacturing method, a decorative sheet is formed along the back surface of the base material 2 including the bent portion 4. However, in this example, since the manufacturing method of the door panel 1 described in detail below was adopted, it was added to the back surface of the base material 2 including the bent portion 4. It is possible to stick the decorative sheet 3 along with certainty.

  As shown in FIG. 1A, a vacuum laminating apparatus 5 used in the method for manufacturing the door panel 1 of the present example has a pair of mating housings 10 and 10 (an upper housing 10a and a lower housing 10b) ), And an opening 18 is formed in each mating portion of the upper casing 10a and the lower casing 10b, leaving the decorative sheet pressing portion 17 at the peripheral edge, and the upper casing 10a and the lower casing 10b When the mating surfaces are matched with each other, a closed space-like laminating processing space 6 constituted by the internal space of the upper housing 10a and the internal space of the lower housing 10b is formed. Although not shown, each matching housing 10 is formed with an intake hole connected to a suction device. One internal space of the matching housing 10 having the suction hole (in this example, the inside of the lower housing 10b). The base material 2 is set (arranged) in the space. As for the arrangement of the decorative sheet 3 in the laminating processing space 6, the peripheral portion 3b of the decorative sheet 3 is sandwiched between the decorative sheet pressing portions 17 that are joined when the pair of matching housings 10 are matched. This is done. In the state where the base material 2 and the decorative sheet 3 are arranged in the laminating space 6 as described above, the back surface of the base material 2 is opposed to the surface (adhesive layer) of the decorative sheet 3 as in the past, and vacuum lamination is performed. The bending part 4 of the base material 2 is located corresponding to the peripheral part 3b of the sheet surface of the decorative sheet 3 held by the device 5 and having little room for deformation. Here, in the state where the base material 2 and the decorative sheet 3 are arranged in the laminating space 6 as described above, the inside of the laminating space 6 is separated by the decorative sheet 3 and separated by the decorative sheet 3. A pair of base materials 2 will be arrange | positioned in one laminated processing space 6 made. For convenience of explanation, the space (in this example, the internal space of the lower housing 10b) in which the base material 2 is arranged among the laminate processing spaces 6 separated by the decorative sheet 3 is defined as the base material arrangement side space 6a. The other space (in this example, the internal space of the upper housing 10a) is referred to as a non-base material arrangement side space 6b.

  As a major feature of the vacuum laminating apparatus 5 of the present example, a pressing means 25 for pressing the sheet surface of the decorative sheet 3 facing the bent portion 4 of the base material 2 toward the back surface of the bent portion 4 is provided. . As shown in FIG. 1B, the pressing means 25 is formed on the bent portion 4 of the base material 2 in one of the matching housings 10 (in this example, the upper housing 10a) whose inner space is the non-base material arrangement side space 6b. The base part 26 is installed on the upper surface portion of the decorative sheet presser part 17 on the corresponding side, and the arm part 27 protrudes from the base part 26 toward the side (opening 18 side). The decorative projecting sheet pressing portion 28 is configured by the lower projecting tip of the arm portion 27 with the side projecting tip projecting downward (lower housing 10 b side). Specifically, the pressing means 25 of the present example has a pair of base portions 26 corresponding to both end portions 2b of the door panel 1 in the width direction, and protrudes the arm portions 27 from the base portions 26 to the side. The decorative sheet pressing portion 28 is configured by connecting the downward projecting ends of the arm portions 27 with a pressing rod 29. Further, the pressing means 25 of this example is provided with a driving means (not shown), and this driving means allows the decorative sheet pressing portion 28 to be inserted into the base material arrangement side space 6a from the opening 18. Yes.

  And as for the manufacturing method of the door panel 1 of this example, after arrange | positioning the base material 2 and the decorating sheet 3 in the lamination processing space 6 of the vacuum laminating apparatus 5 as mentioned above, laminating processing space 6 (base material arrangement | positioning) The side space 6a and the non-base material arrangement side space 6b) are evacuated and the sheet surface of the decorative sheet 3 facing the bent portion 4 of the base material 2 by the pressing means 25 provided in the vacuum laminator 5 is bent portion 4. And then opening the suction device connected to the intake port of the non-base material arrangement side space 6b or supplying air from the intake port to the non-base material arrangement side space 6b. The non-base material arrangement side space 6b is pressurized, a pressure difference is generated between the non-base material arrangement side space 6b and the base material arrangement side space 6a, and the decorative sheet 3 includes a bent portion 4 of the base material 2 It is performed in such a manner that it is attached along the back surface of the material 2. Specifically, the pressing means 25 moves the decorative sheet pressing portion 28 downward by the driving means, so that the peripheral portion 3b of the sheet surface of the decorative sheet 3 that faces the bent portion 4 of the base material 2 is the base material. 2 is pressed toward the bent portion 4.

  Thus, the sticking process to the base material 2 of the decorating sheet 3 (the non-base material placement side space 6b is pressurized and the non-base material placement side space 6b and the vacuumed base material placement side space 6a are Before the step of generating a pressure difference between the two, the peripheral portion 3b of the sheet surface of the decorative sheet 3 is extended by the pressing means 25 so as to be brought close to the concave back surface of the bent portion 4 of the substrate 2. Since it was made, in the sticking process to the base material 2 of the decorating sheet 3 performed after that, the peripheral part 3b of the sheet | seat surface of the decorating sheet 3 is given priority (at the timing ahead of another site | part). 4 can be attached to the concave back surface. Therefore, even if it is the peripheral part 3b of the sheet | seat surface of the decorating sheet 3 with little room for a deformation | transformation, it becomes possible to adhere the decorating sheet 3 along the back surface of the base material 2 containing the bending part 4 reliably. It has been done.

  In this example, the decorative sheet pressing portion 28 is constituted by a pressing bar 29 that is long in the width direction of the base material 2, and the pressing bar 29 is in at least a line contact state with the decorative sheet 3 (specifically, the base material 2 Since the sheet is pressed in a long surface contact state in the width direction of the sheet, the device is also devised to reduce the risk of damage to the decorative sheet 3 by suppressing the concentration of the pressing force on the decorative sheet 3. Yes.

  In addition, it is also preferable to provide a heating means (not shown) in the upper housing 10a of the vacuum laminating apparatus 5, and to heat the decorative sheet 3 by this heating means so as to make it easily deformable. The heating of the decorating sheet 3 by the heating means may be performed simultaneously with the evacuation or may be performed at a timing after the evacuation. According to this, it is possible to more easily attach the decorative sheet 3 along the back surface of the bent portion 4 of the substrate 2. In addition, when heating the decorating sheet 3 in this way, it is also preferable to constitute the adhesive layer 33 using a hot-melt type material that exhibits adhesive force by heating, and the pressing means 25 has a heat resistance against the heat of the heating means. It is also preferable to have the property. Needless to say, the pressing means 25 is also provided with durability against a negative pressure condition caused by evacuation of the laminating processing space 6. Of course, if the decorative sheet 3 is relatively soft and easily deformed due to the thinness or material of the decorative sheet 3, the process of heating the decorative sheet 3 in advance by the heating means to make it soft and easily deformed is as follows. Needless to say, you don't have to.

  Moreover, it is also preferable to provide a driving means for moving the pedestal up and down on a pedestal (not shown) on which the substrate 2 is placed, instead of providing the pressing means 25 with a driving means. By raising the pedestal and thus the base material 2 by this driving means, the base material 2 and the decorative sheet pressing portion 28 can be brought close to each other via the decorative sheet in the same manner as the previous example. Yes, as in the previous example, the decorative sheet 3 can be reliably attached to the back surface of the base material 2 including the bent portion 4.

  Moreover, in the manufacturing method of the said door panel 1, the press of the decorating sheet 3 by the press means 25 should just be performed before the sticking process to the base material 2 of the decorating sheet 3, for example, the press means 25. The timing of pressing the decorating sheet 3 and evacuating the laminating processing space 6 may be performed simultaneously. Similarly to the previous example, the peripheral portion 3b of the sheet surface of the decorative sheet 3 is also pressed by the pressing means 25 and is preferentially attached to the concave back surface of the bent portion 4 (at a timing earlier than other portions). The decorative sheet 3 can be reliably attached to the back surface of the base material 2 including the bent portion 4.

  Further, the pressing means 25 is not provided with a driving means. Instead, the downward projecting portion of the arm portion 27 is projected into the lower housing 10b, and the decorative sheet pressing portion 28 is formed on the concave back surface of the bent portion 4. You may make it use what was formed so that it might be located in a close position. According to this pressing means 25, the decorative sheet 3 is arranged in the laminating space 6 by combining the upper casing 10 a and the lower casing 10 b, and at the same time, the decorative sheet pressing portion 28 applies the sheet surface of the decorative sheet 3. The peripheral edge portion 3 b is pressed and brought close to the concave back surface of the bent portion 4 of the base material 2. Then, when a pressure difference is generated in the laminating space 6, the decorative sheet 3 can be reliably attached to the back surface of the substrate 2 including the bent portion 4 as in the previous example. The pressing means 25 has an advantage that the configuration can be simplified by not providing the driving means.

  Further, as shown in FIG. 5, the pressing means 25 has corners (see FIG. 5) of the flange wall portion 13 a on the upper surface, the flange wall portion 13 b on both side surfaces, and the vertical wall portion 12 on the back surface of the bent portion 4 of the substrate 2. It is also preferable to provide a pair in the upper housing 10a so as to correspond to the A portion in FIG. Specifically, in the pressing means 25, a portion that protrudes downward from the lateral tip of the arm portion 27 is constituted by a hanging rod 30, and the hanging rod 30 is driven up and down by a driving means. . A pressing surface 30a is formed at the lower end of the hanging bar 30, and the decorative sheet pressing portion 28 is configured by the pressing surface 30a. The portions of the back surface of the bent portion 4 that are most difficult to stick along the decorative sheet 3 are the corner portions of the flange wall portion 13a on the upper surface, the flange wall portion 13b on both sides, and the vertical wall portion 12 (in FIG. 4). However, the pressing means 25 of the present example aims at a portion where the peripheral portion 3b of the sheet surface of the decorative sheet 3 is most difficult to stick along the decorative sheet 3 on the back surface of the bent portion 4. When the pressure difference of the laminating processing space 6 is generated, the peripheral portion 3b of the sheet surface of the decorative sheet 3 is preferentially bent (at a timing earlier than other portions). 4, the decorative sheet 3 on the concave back surface of the concave part 4 can be attached to the most difficult part to be attached, so that the decorative sheet 3 is reliably attached to the back surface of the substrate 2 including the bent portion 4. It is made possible to wear.

  Further, in the previous example, the lamination processing space 6 of the vacuum laminating apparatus 5 formed in a space in which only one base material 2 can be arranged is arranged in the same plane as shown in FIG. It forms in the space of the size which can be arrange | positioned, and arrange | positions the two base materials 2 in this lamination process space 6 with the edge parts 2a in which the bending part 4 was formed adjoining, and these adjacent edge parts 2a Is disposed so as to face the central portion 3a of the sheet surface of the decorative sheet 3, and then applied to the back surfaces of the two base materials 2 by the vacuum laminating method using the pressing means 25 provided in the vacuum laminating apparatus 5. It is also preferable to stick the decorative sheet 3. The pressing means 25 of this example is configured by hanging a hanging rod 30 from a base provided on the upper housing 10a as in the previous example, and is the most on the concave back surface of the bent portion 4 of each substrate 2. Four pieces are provided corresponding to the parts that are difficult to stick along the decorative sheet 3. The central portion 3a of the sheet surface of the decorative sheet 3 is preferentially pressed by pressing the central portion 3a of the sheet surface of the decorative sheet 3 by the decorative sheet pressing portion 28 configured by the pressing surface 30a at the lower end of the hanging bar 30. (At a timing earlier than the other part), the base material 2 including the bent part 4 can be attached to the part that is most difficult to stick along the decorative sheet 3 on the concave back surface of the bent part 4. The decorative sheet 3 can be reliably attached to the back surface of the sheet. In particular, in this example, since the base material 2 is disposed in the laminating space 6 so that the bent portion 4 corresponds to the central portion 3a of the sheet surface of the decorative sheet 3 having a relatively large room for deformation, the pressing means 25 In addition to this, the arrangement style of the base material 2 also makes it easy to stick the decorative sheet 3 along the concave back surface of the bent portion 4.
