Description

  The present invention relates to a method for manufacturing a multilayer member in which an elastic material is bonded to a bonding surface of a substrate, and an apparatus for manufacturing a multilayer member that implements this manufacturing method.

  FIG. 7 is a perspective view of an instrument panel IP that is a vehicle body interior member that is disposed in front of the passenger compartment of an automobile and extends in the vehicle width direction from the front of the driver seat to the front of the passenger seat. . The instrument panel IP includes an instrument unit and the like on the driver's seat side, a glove box GB that functions as an accessory case on the passenger seat side, and an audio unit and a car navigation unit in the middle of the vehicle width direction. Etc. are arranged. Further, the instrument panel IP is exposed to a member exposed to the passenger compartment and touched by a hand, for example, an opening / closing lid D that opens and closes the glove box GB, and the synthetic resin base material 110 is exposed to the outer surface due to a grade difference in the same vehicle type. A type or a type in which a skin material 114 is pasted on the outer surface of the base material 110 and a foam material 112 as a sheet-like elastic material is interposed between the base material 110 and the skin material 114 (see FIG. 8). ). That is, the low-grade door D is a single-layer member made only of the base material 110, and the high-grade door D is a so-called “multi-layer member” made of the base material 110, the foam material 112, and the skin material 114. It is said.

  As shown in FIGS. 9A and 9B, the opening / closing door D uses a common base 110 for each grate. For this reason, the gap S between the door D and the decorative panel 120 adjacent to the door D is based on the low-grade door D. However, since the size of the gap S affects the texture of the instrument panel IP, the gap S is set as small as possible in the low-grade door D (FIG. 6A). That is, the gap S is larger than the thickness of the skin material 114, but smaller than the thickness H of the foam material 112. Therefore, in the high-grade opening / closing door D, as shown in FIG. 6B, the outer surface constituting the design surface of the instrument panel IP in the base 110 is defined as the affixing surface 116, and only the affixing surface 116 is a foam material. 112 is affixed so that only the skin material 114 is affixed to the side surface 110 </ b> A of the substrate 110.

  Therefore, conventionally, the foam material 112 is preliminarily formed into a sheet shape having the same outer edge shape as the outer edge shape of the application surface 116, and the formed foam material 112 is applied to the application surface 116 of the substrate 110 by an application device or a manual operation. ing. Such a foaming material sticking apparatus and sticking method are disclosed in Patent Document 1, for example.

JP-A-6-114984

  By the way, since the foam material 112 is an elastic material having elasticity and elasticity, it is difficult to cut and mold it into a prescribed shape which is the same outer edge shape as the outer edge shape of the affixing surface 116 of the base material 110. The processing accuracy of the foam material 112 is about ± 1.0 mm. Moreover, the positioning accuracy of the foam material 112 with respect to the affixing surface 116 of the base material 110 is about ± 0.5 mm. For this reason, when the processing accuracy and positioning accuracy of the foam material 112 are matched, the accuracy of attaching the foam material 112 to the attachment surface 116 of the base material 110 becomes ± 1.50 mm. That is, it is very difficult to affix the foam material 112 to the affixing surface 116 with the outer edge of the affixing surface 116 of the substrate 110 and the outer edge of the foam material 112 aligned. As shown in FIG. In many cases, the foam 112 is affixed in a state where the end 112a of the 112 protrudes from the end surface of the door D or a part of the affixing surface 116 is exposed. When the skin material 114 is pasted on the base material 110 in a state where the end 112a of the foam material 112 protrudes from the side surface 110A of the base material 110, the end surface of the open / close door D is in a bulged state. The skin material 114 comes into contact with the decorative panel 120 to be closed and the opening / closing door D cannot be closed. Further, when the skin material 114 is pasted on the base material 110 in a state where a part of the pasting surface 116 of the base material 110 is exposed, a step is formed on the outer edge portion of the open / close door D. As a result, the manufacturing efficiency of the instrument panel IP decreases and the manufacturing cost increases.

Even when the elastic material 20 is in contact with the upper surfaces of the fixed support portion 52 and the movable support portions 60, 70, 80, the first locking pins 94 and the second locking pins 96 are bonded to the elastic material 20. 24 does not protrude.

  When the setting of the elastic material 20 with respect to the elastic material setting portion 50 is completed, as shown in FIG. 4, the rod 78 </ b> A moves forward through the first fluid pressure cylinder 68 of the first slide mechanism 62 of the first movement support portion 60. Actuating to move the first movement support part 60 forward. Further, the second fluid pressure cylinder 78 of the second slide mechanism 72 of each of the second movement support portions 70 and 70 is operated so that the rod 78A moves forward, and the second movement support portions 70 and 70 are moved to the right. Let Further, the third fluid pressure cylinder 88 of the third slide mechanism 82 of the third movement support portion 80 is operated so that the rod 88A is advanced, and the fourth fluid pressure cylinder 92 is operated so that the rod 92A is advanced. Then, the third movement support unit 80 is moved diagonally right forward. As a result, the first separating edge 28A and the second separating edge 28B separated from the reference portion 27 are removed from the positioning portion 58 while the elastic member 20 is held on the reference portion 27 side opposed to the positioning portion 58. Stretch to move away.

  And if the 1st outer edge detection means 100 detects 28 A of 1st separating edges, while stopping the 1st fluid pressure cylinder 68 of the 1st slide mechanism 62, the movement to the front of the 1st movement support part 60 will be stopped. Then, the third fluid pressure cylinder 88 of the third slide mechanism 82 is stopped, and the forward movement of the third movement support portion 80 is stopped. When the second outer edge detection means 102 detects the second separation edge 28B, the second fluid pressure cylinder 78 of the second slide mechanism 72 is stopped to stop the rightward movement of the second movement support part 70. At the same time, the fourth fluid pressure cylinder 92 of the third slide mechanism 82 is stopped to stop the rightward movement of the third movement support portion 80. As a result, the elastic material 20 is positioned and held on the upper surface of the elastic material setting portion 50 in a prescribed shape.

  Moreover, as shown by a two-dot chain line in FIG. 5, the pasting surface of the base material 10 having the pasting surface 12 formed on the outer surface is set against the set surface 44 of the base material setting unit 40 stopped at the set position. 12 is set in a posture facing the elastic material setting portion 50 side.

  Next, as indicated by a solid line in FIG. 5, the base material set part 40 on which the base material 10 is set is moved to the elastic material set part 50 side on which the elastic material 20 having the specified shape is set, and the base material set part 40 is moved. And the elastic material set part 50 are set as the pasting positions. As a result, the adhesive surface 24 of the elastic material 20 and the affixing surface 12 of the base material 10 face each other with their outer edges aligned, and the elastic material 20 is affixed to the affixing surface 12. Accordingly, the elastic material 20 has the reference surface 27, the outer edge including the first separation edge portion 28A and the second separation edge portion 28B, the sticking surface without the side face 14 of the base material 10 protruding or the sticking surface 12 exposed. 12 and the elastic material sticking process to the sticking surface 12 of the base material 10 is completed.

  When the application of the elastic material 20 to the application surface 12 of the base material 10 is completed, as shown in FIG. 6A, as the skin material application process, the elastic material 20 is covered with the skin material 30 formed in a predetermined shape in advance. In this way, it is pasted on the surface 22 of the elastic material 20, and it is pasted so as to be wound from the side surface 14 to the back surface 16 of the base material 10. Thereby, manufacture of the multilayer member M of an Example is completed.

  When the elastic material 20 having the same outer shape as the specified shape is set in the elastic material setting portion 50, the first outer edge detection means 100 is activated simultaneously with the operation of the first to third movement support portions 60, 70, 80. Since the second outer edge detecting means 102 detects the second separated edge 28B while detecting the first separated edge 28A, the elastic member 20 is not stretched. Further, in the case of the elastic member 20 whose outer shape is larger than the prescribed shape due to a processing error or the like, the first outer edge detection means 100 is the first outer edge detecting means 100 before the first to third movement support portions 60, 70, 80 are activated. Since the first separation edge 28A is detected and the second outer edge detection means 102 detects the second separation edge 28B, it is notified by an error notification means (not shown) or the like.

  Therefore, according to the manufacturing method of the multilayer member of an Example, the elastic material 20 which has the elasticity formed in the magnitude | size whose external dimension does not exceed the external dimension of the affixing surface 12 of the base material 10 is the external shape of the affixing surface 12. Since it is pulled to the specified shape which is the same outer shape as the shape, the processing error at the time of molding or cutting of the elastic material 20 is corrected before being applied to the application surface 12 of the base material 10, and the elastic material 20 is changed to the specified shape. can do. And since it was made to affix this elastic material 20 to the base material 10 in the state which aligned the outer edge of the elastic material 20 made into regular shape, and the outer edge of the affixing surface 12, this elastic material 20 is attached with respect to the base material 10. Thus, it is possible to prevent the elastic material 20 from protruding from the base material 10 and protruding from the base material 10 or from being exposed. Moreover, since the elastic material 20 has a specified shape before being applied to the application surface 12 of the base material 10, the elastic material 20 is slackened to the elastic material 20 as compared with the case where the elastic material 20 is specified shape while being applied to the base material 10. Stretching, wrinkles and the like are unlikely to occur, and the elastic material 20 can be neatly adhered to the affixing surface 12.

  When the elastic material 20 has a specified shape, the first reference edge 27A and the second reference edge 27B of the reference portion 27 provided on the outer edge of the elastic material 20 are replaced with the first positioning edge 58B and the second reference edge 27B of the positioning portion 58, respectively. The first separation edge portion 28A and the second separation edge portion 28B, which are separated from the reference portion 27 at the outer edge of the elastic member 20, are positioned from the reference portion 27 while the corner portion 26 is positioned relative to the positioning edge 58C. Since the elastic material 20 is pulled so as to move in the separating direction, the elastic material 20 can be appropriately stretched to a specified shape. In addition, when the elastic material 20 has a defined shape, the first separation edge 28A is detected by the first outer edge detection means 100 and the second separation edge 28B is detected by the second outer edge detection means 102. The material 20 can be accurately defined. Further, when the elastic material 20 is set in the elastic material setting portion 50, the elastic material 20 is held by the first locking pin 94 and the second locking pin 96 at a portion other than the adhesive surface 24. The first locking pin 94 and the second locking pin 96 do not get in the way when the material 20 is bonded to the substrate 10, and the elastic material 20 can be appropriately bonded to the bonding surface 12 of the substrate 10. .

Further, according to the multilayer member manufacturing apparatus J of the embodiment, the elastic material setting part 50 holds the positioning part 58 for positioning the elastic material 20 and the positioned elastic material 20 so that the reference part 27 does not move. The first and third movements for pulling the elastic material 20 so as to separate the fixed support portion 52 and the first separation edge portion 28A and the second separation edge portion 28B different from the reference portion 27 in the elastic material 20 from the reference portion 27. Since the support portions 60, 70, and 80 are provided, the elastic material 20 whose position is regulated by the positioning portion 58 can be held in the same prescribed shape as the outer shape of the affixing surface 12, and the elastic material 20 is molded. Alternatively, it is possible to correct a machining error at the time of cutting. And by making the elastic material set part 50 which set the elastic material 20 made into the defined shape and the base material set part 40 where the base material 10 is set as the application position, the elastic material 20 and the application surface 12 of the base material 10 It is possible to paste. Thereby, it can prevent that the elastic material 20 sticks to the base material 10 in the state which protruded from the sticking surface 12, or the elastic material 20 sticks to the base material 10 in the state which the sticking surface 12 exposed, and is the multilayer member M. It is possible to prevent deterioration of quality. Moreover, since the elastic member set portion 50 and the base setting portion 40 is defined in the positional relationship and the outer edge is flush outer edge and defining a shape of the elastic member 20 of the joining surface 12 at the pasting position, both sets 50 , 40 can be applied to the application surface 12 accurately and simply while accurately aligning the outer edge of the elastic material 20 and the outer edge of the application surface 12 of the base material 10. .

  And in the manufacturing apparatus J of the multilayer member of an Example, each 2nd provided in each 1st latching pin 94 provided in the fixed support part 52 and each 1st-3rd movement support part 60,70,80. Since the locking pin 96 is inserted into a portion different from the bonding surface 24 of the elastic material 20 and does not protrude into the bonding surface 24, the elastic material 20 can be formed into a defined shape without holding the bonding surface 24. The adhesion surface 24 of the elastic material 20 having the prescribed shape and the affixing surface 12 of the base material 10 can be bonded without being obstructed by the first locking pins 94 and the second locking pins 96. In addition, the manufacturing apparatus J of the embodiment includes a first outer edge detection unit 100 that detects the first separation edge 28A of the elastic member 20 that has been stretched to a specified shape, and a second outer edge that detects the second separation edge 28B. Since the detecting means 102 is provided, it can be accurately and easily determined that the elastic material 20 set in the elastic material setting section 50 has a specified shape. Then, when the first outer edge detecting means 100 detects the first separation edge portion 28A, the forward movement of the first movement support portion 60 and the third movement support portion 80 is stopped and the second outer edge detection means 102 is second. When the separation edge portion 28B is detected, the elastic member 20 can be held in a specified shape by stopping the rightward sliding movement of the second movement support portion 70 and the third movement support portion 80.

  On the other hand, according to the manufacturing method of the multilayer member M using the said manufacturing apparatus J, the base material by which this elastic material 20 was affixed in the state which aligned the outer edge of the elastic material 20 of regular shape, and the outer edge of the affixing surface 12 10, the skin material 30 is pasted so as to cover the elastic material 20, so that a part of the skin material 30 does not protrude or dent and a step is not formed. Therefore, it is possible to manufacture a multilayer member M with high quality and stability.
