Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a coating device suitable for coating a viscous material such as an adhesive in a thread or strip shape.

<Prior art and problems> As a device for applying a viscous material such as an adhesive or caulking to an adherend, a coating liquid supply port is provided on one side of a cylindrical container containing the coating liquid and a coating liquid flow is provided on the other side. A coating device called a caulking gun having an outlet (nozzle). Further, recently, it has become possible to see a coating apparatus in which a coating liquid supply port is provided on the cross section of one pipe-shaped container and a large number of outlets are provided on the side surface. But,
With the former caulking gun, it was possible to apply only one strip, and it was impossible to use it for a wide adherend. Further, in the latter device, the outflow amount was large from the nozzle close to the coating liquid supply port, and only a small amount could flow out from the nozzle far from the supply port, resulting in uneven coating. Further, since the nozzle interval is constant, the amount of coating cannot be adjusted by changing the viscosity of the coating liquid.

<Purpose of the Invention> The purpose of the present invention is to have a large number of outlets so that even a wide adherend can be applied, and the amount of outflow from each outlet is almost constant, and depending on the adherend. An object of the present invention is to provide a coating device that can freely change the coating width and the coating interval.

<Disclosure of the Invention> The gist of the present invention is as described above. To explain with reference to an example of the drawing, FIG. 1 is a plan view of an applicator of the present invention seen from the adherend side, and FIG. FIG. 3 shows a side view, and FIG. 3 shows a sectional view of one applicator.

A plurality of (three in the drawing) horizontally long tubular applicators (11) (12)
(13) are set in parallel so that they can be slid respectively in partition frames (61) (62) provided in a rectangular set chamber (5) in the lengthwise direction. Each of the applicators (11) has a supply port (21) (22) for the coating liquid (R), and an outlet (31) (32) (33) (34) ... Underneath. Through the open / close valves (41) (42) to the supply ports (21) (22).
It is connected to a supply pipe (P) for the coating liquid (R). The supply amount of the coating liquid (R) to the applicators (11) (12) (13) is adjusted by the open / close valves (41) (42). Further, the amount of application to the adherend is adjusted by the diameters and intervals (pitch) of the outlets (31) (32) (33). Further, the coating width can be changed depending on the number of sets of coating tools. In addition, the applicator (11) and the other applicator (12) can be separately applied with different compositions, for example, a high viscosity product and a constant viscosity product. Further, the applicator (11) and the applicator (12) can be applied partially or wholly overlapping each other.

<Effect of device> Since the applicator of the present invention sets a plurality of applicators each having a coating function in parallel and can slide in the same direction, the number of applicators set can be changed according to the application width of the adherend. it can. Therefore, the loss of the coating liquid is smaller than that of the conventional single coating device. Since the gap between the supply ports of the coating liquid is short, the discharge amount from the outlet is likely to be constant, and uneven coating is less likely to occur as compared with the conventional product. Since the applicator and other applicators can be applied separately as separate components, such as thermosetting resin and elastomer, application work to composite materials (adhesive materials consisting of both hard and soft materials, etc.) Can be done at once.
In addition, since the applicator and the other applicator can be applied in an overlapping manner, the amount of application to the adherend can be changed by the composite material (non-porous material, porous material, etc.).
