While the reciprocating mechanism 52 operates, the receiving jig 50 that supports the core material 13 (the object to be processed) can be reversed approximately 180 °, and the core material 13 is bonded to the front and back surfaces. It is comprised so that application | coating of an agent can be performed easily. As the transport mechanism 51, a well-known conventional means such as a belt conveyor system, a cylinder drive system, a feed screw mechanism system, or the like can be used. Further, as the reversing mechanism 52, a system using a stepping motor that rotates intermittently every 180 ° is employed.

  More specifically, the adhesive application booth 30 is equipped with an adhesive application gun 31 so that the adhesive can be spray applied, and a box 32 is provided in the adhesive application space. A duct port 33 for connection to an exhaust duct (not shown) is provided so that the organic solvent and the like can be discharged to the outside. The core member 13 in the inscribed member 12 is set on the receiving jig 50, but the skin 14 is positioned and set on the skin mounting table 34 on the near side of the receiving jig 50.

The conveying mechanism (51) of the receiving jig (50) is driven to slide the receiving jig (50) supporting the core (13) from the adhesive application booth (30) to the adhesive drying furnace (40). , An adhesive drying step of drying the adhesive by the heater (41) in the adhesive drying furnace (40);
The adhesive application gun (31) is used for the skin (14) placed on the skin mounting table (34) in the adhesive application booth (30) during the drying treatment of the adhesive applied to the surface of the core material (13). And applying the adhesive to the epidermis to apply the adhesive,
The receiving jig (50) is conveyed from the adhesive drying furnace (40) to the adhesive application booth (30), and the core material (13) on the receiving jig (50) is operated by the reversing arm (53). A temporary press-bonding step of the skin and core material to be temporarily press-bonded to the skin (14) on the skin mounting table (34);
Masking is put on the back surface of the core material (13), and the adhesive to the winding portion for applying the adhesive from the adhesive application gun (31) to the peripheral edge portion of the core material (13) and the outer skin (14) back surface winding portion. Application process;
An adhesive drying step for drying the adhesive applied in the step;
A method for applying and drying an adhesive comprising the steps of: The adhesive (12) in the bonded product (12) is formed by adhering and fixing the skin (14) to the surface of the core (13), and winding the peripheral edge (14a) of the skin (14) around the back of the core (13). An application / drying device (20),
The adhesive application / drying device (20) includes an adhesive application booth (30) having an adhesive application gun (31) and an adhesive drying furnace (40) having heaters (41, 42). Two stages are provided adjacent to each other, and the receiving jig (50) for supporting and fixing the core material (13) in the bonded product (12) has a transport mechanism (51) for reciprocating between both stages. And a reversing mechanism (52) for reversing the receiving jig (50), and by reversing the receiving jig (50), the adhesive can be applied to the front and back surfaces of the core (13). The applied adhesive is conveyed into the adhesive drying furnace (40) as a continuous process, and heaters (41, 42) are provided on the upper and lower sides, respectively, and the adhesive on the front and back surfaces of the core material (13) is collected all together. Applying and drying the adhesive, characterized by drying . The adhesive (12) in the bonded product (12) is formed by adhering and fixing the skin (14) to the surface of the core (13), and winding the peripheral edge (14a) of the skin (14) around the back of the core (13). A coating / drying device (20A),
The adhesive application / drying apparatus (20A) has two stages: an adhesive application booth (30) having an adhesive application gun (31) and an adhesive drying furnace (40) having a heater (41). Is provided adjacent to the receiving jig (50) for supporting and fixing the core (13) in the bonded product (12), and a transport mechanism (51) for reciprocating between both stages, A reversing arm (53) for reversing the core material (13) on the receiving jig (50) to the skin mounting table (34) side is provided, and is provided for the skin (14) on the skin mounting table (34). An adhesive application / drying device characterized in that the core (13) and the skin (14) can be temporarily pressed by reversing the reversing arm (53).
