SPACE BAR ADHESION LIQUID COATING SYSTEM FOR DUPLICATED GLASS}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adhesive liquid applying apparatus for applying an adhesive liquid to both surfaces of an liver rod interposed between a pair of glass, and in particular, to provide a gap between the first and second nozzle portions for injecting the adhesive liquid to both sides of the liver rod while passing the liver rod. It is possible to adjust the automatic, and furthermore, the interlayer adhesive rod coating liquid coating device for laminated glass that can be held in constant contact with the transfer belt regardless of whether the seating portion of the liver rod to which the adhesive liquid is applied by being applied to the transfer belt is flat or curved. will be.

As shown in FIG. 1, a general multilayer glass is framed in a shape of a space bar 2 which maintains a gap between the glass plates 1 and 1 ′ between a pair of glass plates 1 and 1 ′. After the adhesive liquid 3 is applied to both sides of the liver rod 2, the glass plate member 1 is adhered to both sides of the liver rod 2 by applying a predetermined pressure and heat in a vacuum state. As a result, the soundproofing and the warming effect are excellent by the vacuum part formed between the glass plate 1 and 1 ', and it is widely used as a building material recently.

In the manufacturing process of such a multilayer glass, the application | coating of the adhesive liquid on both surfaces of the liver bar has been performed by the manual work in general. However, such a method of applying the adhesive liquid by manual operation takes a lot of time, and also because the adhesive liquid is not applied to both sides of the liver rod with a uniform thickness, the glass plate material does not adhere smoothly to both sides of the liver rod. Even after manufacturing, there was a problem in that the vacuum portion between the glass plates could not be maintained in a completely sealed state. In addition, there is a problem that the gel-type adhesive liquid may flow to other parts other than the coated surface, so that a careful attention of the operator is required during the application.

Accordingly, the present applicant has already filed the application of the liver stick adhesive liquid coating device as a domestic utility model (Registration No. 250837) in order to solve the problems caused when the liver stick adhesive liquid is manually applied as described above.

Applicant of the present applicant application for the interlayer glass liver stick adhesive liquid coating apparatus, the body 100 is provided with a work table (100a) at the top, the belt conveyor 110 is transported in the forward or reverse direction from the upper surface of the work table (100a) And first and second guide bars 120a and 120b respectively installed on both sides of the work table 100a to guide the insertion path of the liver rod 2a seated on the belt conveyor 110, and the liver rod 2a. The first and second detection sensors 130a and 130b for detecting the position of the) and the upper surface of the seating portion of the liver rod 2a detected by each of the detection sensors 130a and 130b are pressed and supported to the belt conveyor 110. And the first and second guide rollers 140a and 140b for releasing the pressing after the set time has elapsed, the coating device 150 for coating the liver stick adhesive liquid on both surfaces of the liver sticking body 2a, and the coating device 150. It comprises an adhesive liquid supply device 160 for supplying the liver stick adhesive liquid).

At this time, the coating device 150 is made to spray the adhesive liquid on both sides of the liver rod from the first and second nozzle parts 150a and 150b installed to face each other on both sides of the belt conveyor 110 on the upper surface of the work table 100a. The first nozzle part 150a is provided with a position adjusting part 158 for adjusting the position of the first nozzle part 150a so as to adjust a distance from the second nozzle part 150b.

According to the liver rod adhesive liquid applying device for multilayer glass configured as described above, since the advancing direction of the adhesive liquid applying operation can be reciprocated in the forward direction or the reverse direction, the working time can be shortened to improve the productivity, and Since the thickness can be kept constant, the quality of the product can be improved, and the application of the liver sticky adhesive solution can significantly reduce the consumption of the liver sticky adhesive liquid because there is no fear of the adhesive liquid flowing or splashing.

However, in the conventional liver-clad adhesive liquid coating apparatus configured as described above, the position adjusting portion for adjusting the position of the first nozzle portion is rotated by hand, so it is difficult to precisely adjust the gap between the first and second nozzle portions. In addition, it took time to adjust the gap, and in the case of the first and second guide rollers that compress the seating portion of the liver rod to the belt conveyor side when the adhesive liquid is applied, the seating portion of the liver rod is curved to the curved surface. If formed, its use was difficult.

Accordingly, the present invention has been made in order to solve the problems caused by the use of the conventional liver rod adhesive liquid coating apparatus for the above-described laminated glass, the first and second nozzles by spraying the adhesive liquid on both sides of the liver rod while passing through the liver rod The gap between the parts can be automatically adjusted, and the rod adhesive is evenly formed on both sides of the rod by being pressed against the surface of the transfer belt to maintain a constant height regardless of whether the seating portion of the rod that is seated on the transfer belt is flat or curved. It is an object of the present invention to provide an apparatus for applying liver stick adhesive liquid for multilayer glass.
