Description

[Detailed description of the invention] (Field of industrial application) This invention is an effective method for adhering seat skin materials to mass produce seats with excellent design, such as automobile seats with deep grooves on the seat surface. It is related to the device.

(Prior art) A seat pad having a groove on the seat surface is set. An upper mold having a mold surface having a protuberance corresponding to the groove is placed above the lower mold and interposed between the two molds. A skin material bonding device for seats, which adheres a skin material to the surface of a seat pad during mold matching, is already known from Japanese Patent Laid-Open Publication No. 59-22591.

(Problem that the invention aims to solve) However, when bonding skin materials with a conventional device of this kind, the setting position of the skin material is shifted, and the skin material is pressed and tensed by the ridges to be pushed into the groove, which causes the skin material to be pushed into the groove. If the grooves are deep, the opening edges of the grooves will be crushed by the tense skin material, the corners will disappear, and the finish will be poor.

(Means for Solving the Problems) The present invention has been completed with the aim of solving the above-mentioned problems and creating an apparatus for adhering skin materials for seats that can easily mass-produce seats with deep grooves and an excellent design. A skin material for seats, in which one mold for setting the seat pad is opposed to the other mold for adhering the skin material, and the skin material is interposed between both molds and adhered to the surface of the seat pad when the molds are aligned. In the bonding device, a ridge corresponding to the groove formed on the surface of the sheet pad is provided on the mold surface of the other mold for adhering the skin material, and a temporary skin material holding portion is provided around the base of the ridge, and further, both of the molds are The present invention is characterized in that a setting jig is provided between the molds, which intervenes between the two molds when the molds are opened, and causes the skin material to conform to the ridges.

(Function) This device for adhering skin materials for seats first opens both molds and applies adhesive to the surface of the seat pad, which has deep grooves on the seat surface, including the inside of the grooves. Set in one mold.
Next, a skin material is set between the two molds with its peripheral edge clamped by a clamp mechanism, and a set jig is installed on the underside of the skin material, which has a recess large enough to loosely fit the protuberance of one of the molds. Then, by inserting the recess of the setting jig into the ridge of one mold through the skin material, a part of the skin material is folded so that it completely follows the ridge surface, and the base of the ridge is folded. The part of the skin material following the folded part is temporarily held in the skin material temporary holding part provided around the skin material, and if the setting jig is removed in this state and the two molds are matched, the skin material will be removed. Since the material is adhered to the surface of the pad material in a shape corresponding to the surface shape of the pad material, all that is required is to open the mold and remove the product from the other mold.

(Embodiment) Next, the present invention will be explained in detail with reference to the illustrated embodiment. 1 is one mold for setting the seat pad 11;
The other mold 2 for adhering the skin material, which has a mold surface of a shape corresponding to the surface shape of the surface material, is placed opposite the mold 2 so that the molds can be freely matched, and reference numeral 3 denotes a skin material clamping mechanism provided on the outer periphery between the molds 1 and 2. These basic configurations are unchanged from those known in the art. Reference numeral 4 denotes a leg plate-shaped ridge with a narrow width and an arcuate tip formed on the mold surface of the other mold 2, and the ridge 4 is formed on the surface of the sheet pad 11 set in one of the molds 1. It has a shape corresponding to the groove 12 for drawing in the skin material. 5 is the bulge 4 on the mold surface of the other mold 2.
If the skin material 21 to be bonded is made of fabric, clothing or the like is used as the skin material temporary holding part 5, which is provided around the base of the skin material 21. If the material is not breathable, such as leather, it may be a suction hole connected to a suction source. Reference numeral 6 denotes a gutter-shaped setting jig that is provided slightly below the installation surface of the clamp mechanism 3 between the molds 1 and 2 so as to be able to move forward and backward toward the lowered position of the protuberance 4; A recess is formed into which the bulge 4 is loosely fitted, and when the mold is opened, it is inserted between the two molds 1 and 2, and after a part of the skin material 21 is aligned with the bulge 4, the two molds are removed before the molds are completely matched. It is designed to retreat to the outside from between 1 and 2.

With this structure, the mold 2 is placed in an open state with the other mold 2 raised, and the deep groove 1 is first opened.
A seat pad 11 made of polyurethane foam or the like having 2 formed on the seat surface is set in one mold 1 with an adhesive 13 applied from the inner surface of the groove to the seat surface. Next, the skin material 21 is clamped to the skin material clamping mechanism 3 provided on the outer periphery between the molds 1 and 2.
1 is interposed between both molds 1 and 2, and a gutter-shaped setting jig 6 is introduced into the lower position of this skin material 21, and then the ridge 4 provided on the mold surface of the other mold 2 and the setting jig are inserted. If the tool 6 is moved in the direction in which it is fitted with the recessed part, a part of the skin material 21 set between the setting jig 6 and the other mold 2 will become raised 4.
and the concave portion of the setting jig 6 to form a pleated portion, and the portion continuing to the base of this pleated portion is a flat portion of the mold surface of the other mold 2 that continues to the base of the protuberance 4. Since it comes into contact with the skin material and is temporarily held by the skin material temporary holding part 5 provided at this part, next,
Even if the gutter-like setting jig 6 and the protuberance 4 are disengaged, the skin material 21 will continue to lie along the mold surface of the other mold 2. Once the skin material 21 is in line with the mold surface of the other mold 2 in this way, the other mold 2 is lowered or one mold 1 is raised to separate the heated molds 1 and 2. If the molds are matched, the protuberance 4 has a shape that corresponds to the groove 12 of the seat pad 11, so most of the skin material 21 is pressure-bonded to the seat surface of the seat pad 11, and the pleated portions are formed by the thickness of the skin material 21. Even if the width of the skin material 21 is larger than the groove width of the groove 12, it will be pushed into the groove 12 without difficulty and the outer surface will be bonded to the inner surface of the groove. Because it is formed into the shape of the seat surface, the opening edge of the groove 12 is not crushed by the tension of the skin material 21, and the seat pad 11 set in one mold 1 is partially Since the skin material 21 is bonded with almost no deformation, all that is left to do is to open the mold and take out the product.

(Effects of the invention) As is clear from the above description, the present invention allows the skin material to be accurately and easily adhered to the seat pad without deformation, making it possible to mass-produce seats with deep grooves and an excellent design. It has extremely great practical value as a skin material bonding device.
