  By the way, as a manufacturing method of the makeup joint material 310 of the said nonpatent literature 1, the following methods can be considered. For example, as one method, a method of extruding only the main body 311 and then attaching a cosmetic aluminum foil 312 previously formed in a U-shape to the main body 311 can be considered, but the cosmetic aluminum foil 312 is generally thin. Therefore, it is very difficult to store the U-shaped one so as not to be deformed (when it is a single unit) or attach it to the main body 311 without being deformed. As a method capable of solving this problem, an insert molding method in which a flat aluminum foil and a thermoplastic resin are simultaneously supplied to an extrusion molding apparatus and the resin is extruded while the aluminum foil is deformed into the U shape can be considered. . However, in this method, not only high technology is required to prevent the deformation of the aluminum foil for cosmetics due to heat during extrusion while the aluminum foil is deformed into the U shape, not only the production There is a problem that it is difficult to improve.

  Then, this invention makes it a subject to provide the cosmetic joint material which can be produced easily and can improve productivity, and its manufacturing method.

  The inventor of the present application sets the decorative sheet when the surface of the joint material is set to be flush with the surface of the panel material in a state in which the decorative joint material is fitted in the groove formed on the surface of the panel material. It was noted that it would be sufficient to provide only on the surface of the decorative joint material.

  Here, since the width of the decorative joint material is as narrow as 2 to 3 mm, for example, the resin main body meanders during extrusion molding or after cooling, or when the decorative sheet is stuck on the surface of the main body. Or meandering is more likely to occur. That is, in the state where the decorative sheet is stuck on the surface, the resin main body is easily exposed, and as a result, it is difficult to ensure a good aesthetic appearance. Therefore, the present invention also aims to solve these problems.

  That is, the present invention is configured as follows to solve the above-described problems.

First, the invention according to claim 1 of the present application is a decorative joint material that is fitted to a groove formed on the surface of the panel material so as to be flush with the surface, and the side that is flush with the surface is a long bottom side. A substantially trapezoidal bar-shaped main body, and a decorative sheet attached only to a surface that is flush with the main body, and a surface formed by connecting the long bottom sides of the main body, possess a back which is substantially V-shaped groove provided, on the surface, a coupling body having a small guide groove is provided than the groove along a position where the substantially V-shaped groove is provided After forming by extrusion molding, a decorative sheet is pasted on the entire surface of the connecting body , and then the connecting body is cut by inserting a cutter along the guide groove from the surface side on which the decorative sheet is pasted. It is manufactured by this.

The invention according to claim 2 is composed of a rod-shaped main body having a substantially trapezoidal cross section and a decorative sheet affixed only to the surface on the long bottom side of the main body, and formed on the surface of the panel material. A method of manufacturing a decorative joint material that is fitted to the groove so as to be flush with the surface, wherein a surface formed by connecting the long bottom side of the main body and a substantially V-shaped groove are provided. possess a back, to the surface, and the extrusion process a small guide groove than the groove along a position where the substantially V-shaped groove is provided is formed by extruding a connecting member provided, A sticking step of sticking a decorative sheet to the entire surface of the connection body extruded by the extrusion molding step, and a connection body on which the decorative sheet is attached in the sticking step from the surface side to which the decorative sheet is attached. switching along a guide groove for cutting put cutlery Characterized by a step.

  Next, the connecting body 11 'to which the primer 21' is applied is cut in the vertical direction along the V-shaped groove 11c 'by the vertical cutting device 37 (cutting process). Specifically, as shown in FIG. 3, the longitudinal cutting device 37 is disposed above the coupling body 11 ′ so as to face in the vertical direction (conveying direction of the coupling body 11) so that the cutting edge becomes higher toward the upstream side. The blade 37a is inserted into the blade 37a from above along the V-shaped groove 11c ', so that the connecting body 11' to which the primer 21 'is applied is removed from the decorative sheet 13' side. As shown in FIG. 4 (e), a plurality of strips 10 ″... 10 ″ are cut.

  Next, a plurality of strips 10 ″... 10 ″ cut by the vertical cutting device 37 are cut into decorative joint materials 10. Specifically, as shown in FIG. 3, the lateral cutting device 38 has a blade 38 a disposed so as to face the lateral direction above the cut member 10 ″... 10 ″, and the blade 38 a By inserting from above, a plurality of strips 10 "... 10" are cut from the decorative sheet 13 'side. Thereby, the makeup joint material 10 in which the decorative sheet 13 is provided only on the surface 10a is manufactured.

As described above, the decorative joint material 10 according to the present reference example is fitted and flush with the groove 2b formed on the surface 2a of the surface panel 2 of the door 1 so as to be flush with the surface 2a. The main body 11 has a substantially trapezoidal cross section whose side is a long bottom side, and a decorative sheet 13 attached only to the surface 11a (surface 11a) on the side that is flush with the main body 11.

  Therefore, the decorative joint material 10 can be manufactured by an easy method without using the insert molding method. In addition, a plurality of decorative joint materials 10 ... 10 can be manufactured at a time, and productivity is improved.

  Further, since the width of the connecting body 11 'is larger than the width of one main body 11, the meandering of the main body 11 (connecting body 11') is less likely to occur during extrusion molding or subsequent cooling. In addition, since the width of the decorative sheet 13 'to be applied is larger than when the decorative sheet 13' is applied to one main body 11, the sheet 13 'is less likely to meander when the decorative sheet 13' is applied. Therefore, in the state where the decorative sheet 13 'is affixed, the width end of the decorative sheet 13' and the width end of the main body 11 'are difficult to shift at the width end of the coupling body 11'. Further, the decorative sheet 13 and the width end of the main body 11 always coincide with each other at the cut portion between the main bodies 11. Therefore, a good aesthetic appearance of the decorative joint material 10 can be ensured.

  Even in this case, if the deviation between the width end of the decorative sheet 13 'and the width end of the connecting body 11' does not satisfy a predetermined standard determined by the manufacturer, etc., the connecting body 11 ' Each one on the width end side (both or not satisfied) may not be a product. By doing so, the cosmetic joint material 10 as a product becomes only one in which the width end of the decorative sheet 13 and the width end of the main body 11 are completely matched, and only the cosmetic joint material 10 having an excellent aesthetic appearance can be supplied. it can. In addition, when it is assumed in advance that the product at the width end side is not a product, the yield can be improved by increasing the number of the main bodies 11 constituting the coupling body 11 ′.

  Moreover, according to this manufacturing method, the primer which raises the bond strength of the adhesive 20 for fixing to the groove | channel 2b of the said panel material 2, and the main body 11 on the surface 11b of the short base side of the main body 11 of the decorative joint material 10 The decorative joint material 11 to which 21 is applied can be easily manufactured in a series of steps.

  In the cutting process, the connecting body 11 ′ to which the decorative sheet 13 ′ is applied in the applying process is changed from the surface side (front surface 11a ′ side) to which the decorative sheet 13 ′ is applied to the V-shaped groove 11c ′ of the back surface 11b ′. Therefore, even if burrs are generated, the burrs will protrude on the back side opposite to the front surface 10a of the decorative joint material 10, so that It is prevented that the beauty of the surface 10a side of the joint material 10 to which the decorative sheet 13 is affixed is damaged by burrs.

In addition , you may provide a primer application process in the upstream of a sticking process between the said extrusion molding process and the said cutting process. Specifically, a primer coating device 36 may be provided between the take-up device 33 and the adhesive coating device 34 in FIG. 3, and the same decorative joint material 10 can be manufactured also by this.

  Further, the configuration of the cosmetic joint material manufacturing apparatus is not limited to that of FIG. 3 or the above-described modified example, and two examples will be described below as other examples.

  First, the first other example will be described with reference to FIG. 5. In this manufacturing apparatus 30 ′, a lateral cutting device 38 is provided on the immediately downstream side of the primer coating device 36 as compared with that in FIG. 3. The vertical cutting device 37 is provided separately from the production line. According to this, this manufacturing method can be realized even when the length of the line is limited.

  Next, a second other example will be described with reference to FIG. 6. In this manufacturing apparatus 30 ″, a cooling water tank 32 is provided on the downstream side of the decorative sheet sticking apparatus 35 as compared with that in FIG. 3. The adhesive sheet applying device 35 is configured such that the decorative sheet sticking device 35 sandwiches the uncooled and still hot connector 11 'and the decorative sheet 13' between the upper and lower rollers 35b and 35c. 13 'is configured to be thermocompression bonded to the connecting body 11'. According to this, the cost of the adhesive application device can be reduced, and the length of the line can be shortened. The decorative joint material produced by this production method does not have an adhesive (12) layer, but this cosmetic joint material and the production method thereof. Is the main departure It is included in the.

  In this second other example, the decorative sheet 13 'may be wound around the decorative sheet supply roll 35a in a state where an adhesive is previously applied to the back surface of the decorative sheet 13'. The above-described effects can be obtained while improving the adhesion with 11 '.

  Next, a method for attaching the decorative joint material 10 to the door 1 will be described.

  First, as shown in FIG. 7A, an adhesive 20 ′ is filled in the lower part of the groove 2 b of the surface panel 2 of the door 1.

  Next, as shown in FIG. 7B, the decorative joint material 10 is temporarily fitted into the groove 2b filled with the adhesive 20 '. Note that this temporary fitting is performed so that the decorative joint material 10 protrudes outward from the groove 2b.

  Next, as shown in phantom lines in FIG. 7 (b), the roller 40 is relatively moved in the longitudinal direction of the decorative joint material 10 while being pressed against the decorative sheet 13 of the decorative joint material 10 from above, As shown in FIG. 7C, the decorative joint material 10 is finally fitted into the groove 2b. By doing so, the surface 10a of the decorative joint material 10 (the surface of the decorative sheet 13) is flush with the surface 2a of the front panel 2, and the main body 11 made of resin is hidden in the groove 2b. Only the decorative sheet 13 becomes visible from the outside. Note that the adhesive 20 'overflowing from the inside of the groove 2b (shown by phantom lines) may be wiped off.

  Thus, according to this attachment method, when the above-described decorative joint material 10 is used, the surface 10a of the decorative joint material 10 and the surface 2a of the front panel 2 can be easily made uniform. it can.

Next, a decorative joint material according to a second reference example will be described. The door side groove structure is the same as that of the first reference example .

  That is, in this decorative joint material 110, as shown in FIG. 8, the width of the both sides 111 c and 111 c of the main body 111 extends to the vicinity of the tip positions of the corners 111 e and 111 e at both ends on the front surface 111 a side on the back surface 111 b side. Projections 111d and 111d projecting in the direction are provided.

The manufacturing method of this decorative joint material 110 is substantially the same as that of the first reference example , but in the extrusion molding process, the surfaces 111a ... 111a side of a plurality of main bodies 111 ... 111 are connected as shown in FIG. And a back surface 111b 'provided with a substantially V-shaped groove 111c', and both side surfaces 111c and 111c of the main body 111 are opposite to the opposite corners of the surface 111a side on the back surface 111b side. A coupling body 111 ′ provided with protrusions 111d and 111d protruding in the width direction to the vicinity of the tip positions of the portions 111e and 111e is formed by extrusion molding. After that, through the same process as in the first reference example , this shape decorative joint material 110 is manufactured.

  According to this decorative joint material 110, when the decorative joint material 110 is tilted even a little when the decorative joint material 110 is fitted in the groove 2b of the front panel 2, as shown by a virtual line α in FIG. Either one of the protrusions 111d comes into contact with the side surface 2c of the groove 2b. Therefore, it is suppressed that the makeup joint material 110 inclines greatly.

Next, a decorative joint material according to a third reference example will be described.

  That is, in this decorative joint material 150, as shown in FIG. 10, a plurality of ribs 151e... 151e extending continuously in the longitudinal direction of the main body 151 are parallel to the lower surface 151b (the surface on the short bottom side) of the main body 151. Is provided. These ribs 151e... 151e have flexibility by being narrowed in width and can be compressed and deformed up and down. Further, the height h1 ′ of the decorative joint material (the height from the surface of the decorative sheet 153 to the tip of the rib 151e (including the primer 21)) is the same as the depth h2 ′ of the groove 2b of the surface panel 2. .

According to the decorative joint material 150 according to the third reference example , when the surface 150a is fitted in the groove 2b of the surface panel 2 so that the surface 150a is flush with the surface 2a of the surface panel 2, each rib 151e. ... the tip of 151e comes into contact with the bottom surface 2d of the groove 2b of the front panel 2.

  Therefore, the cosmetic joint material 150 is prevented from entering the back of the groove 2b to such an extent that the flushness between the surface 150a and the surface 2a of the front panel 2 is impaired, and either the left or right of the cosmetic joint material 150 is prevented. Only one side is prevented from entering the groove 2b and tilting the joint material 150. That is, good uniformity between the surface 150a and the surface 2a of the front panel 2 is ensured.

  In addition, for example, due to formation errors, the depth of the groove 2b is slightly smaller than the design value, or the height of the decorative joint material 150 is slightly larger than the design value, or both of these occur, and as a result, fitting Even if a situation occurs such that the tip of the rib 151e... 151e abuts against the bottom surface 2d of the groove 2b in the middle, the rib 151e... 151e can be compressed and deformed by the rib 151e. It can be pushed into 2b.

The height of the decorative joint material 150 may be slightly larger than the depth of the groove 2b. In this way, even if the formation error of the groove 2b and the decorative joint material 150 is taken into account, in most cases, the tips of the ribs 151e... 151e come into contact with the bottom surface 2d of the groove 2b in the middle of the fitting. It is avoided that the material 150 is pushed deeper than the front surface 2a of the front panel 2, and a uniform surface is realized by compressive deformation of the ribs 151e. Moreover, in the thing of this reference example , you may provide the protrusion (111d, 111d) in a 2nd reference example . By doing so, the joint material is more effectively prevented from being inclined in the state in which the decorative joint material is fitted into the groove 2b of the front panel 2.

The manufacturing method of the decorative joint material 150 is substantially the same as that of the first reference example. However, in the extrusion molding process, a plurality of the main bodies 151 are connected in the same manner as the above-described reference examples. Formed by extrusion. After that, through the same steps as in the first reference example , the decorative joint material 150 of this shape is manufactured.

Next, the manufacturing method of the cosmetic joint material which concerns on embodiment of this invention is demonstrated . The decorative joint material produced by this production method is used in the same manner as in the first reference example . The same manufacturing apparatus as that in the first reference example is used.

In this embodiment , as shown in FIG. 11 (a), in the extrusion process, a guide groove 211d ′ is formed on the front surface 211a ′ along the position where the V-shaped groove 211c ′ of the back surface 211b ′ is provided. The connected body 211 ′ is formed. The guide groove 211d ′ is for fitting the blade 37a of the longitudinal cutting device 37, has a substantially V-shaped cross section, and is smaller in width and depth than the V-shaped groove 211c ′.

  Next, as shown in FIG. 11B, an adhesive 212 'is applied to the surface 211a' of the coupling body 211 '. In addition, as the adhesive 212 ′, an adhesive having fluidity is used so as to easily flow into the guide groove 211 d ′.

  Next, as shown in FIG. 11C, a decorative sheet 213 ′ is affixed to the surface 211a ′ to which the adhesive 212 ′ has been applied. In that case, a decorative sheet 213 ′ is stuck along the inner surface of the guide groove 211d ′ in the guide groove 211d ′ portion of the coupling body 211 ′. This is possible by configuring the outer peripheral surface of the upper roller 35b of the decorative sheet sticking device 35 with a material having flexibility, for example.

  Next, as shown in FIG. 11 (d), the primer 21 ′ is applied to the back surface 211 b ′ (the back surface 211 b... 211 b of each main body 211... 211) of the coupling body 211 ′ to which the decorative sheet 213 ′ is affixed.

  Next, as shown in FIG. 11 (e), the connecting body 211 'to which the primer 21' is applied is inserted into the blade 37a along the guide groove 211d 'from the surface side to which the decorative sheet 213' is applied. And cut in the vertical direction (cutting step).

Next, as in the first reference example , the strip material cut in the longitudinal direction is cut into a predetermined length. And thereby, it will isolate | separate as the cosmetic joint material 210 in which the decorative sheet 213 was provided in the surface 210a.
