Description

[Detailed Description of the Invention] This invention relates to an adhesive application device for applying adhesive to a frame such as a panel frame.

Conventionally, when applying an adhesive for adhering a surface material or a decorative material to a panel frame, the panel frame 3 is passed between an application roll 1 and a support roll 2 facing it, as shown in FIG. Coating is in progress. The application roll 1 and support roll 2 are made of rubber. An adhesive supply roll 4 is rolled into contact with the side of the application roll 1, and this adhesive supply roll 4
The adhesive 5 stored between the roller 1 and the coating roller 1 is supplied to the circumferential surface of the coating roller 1. The panel frame 3 is made of wood. However, if there is a step 6 on the surface of the panel frame 3 at the joint of the frame materials, etc. as shown in the figure, the application roll 1 cannot follow the surface of the panel frame 3, and the adhesive 5 is not applied. There was a problem with some parts. Further, since the conventional applicator roll 1 and support roll 2 are made of rubber, they suffer from severe wear and maintenance is troublesome. Therefore, we considered making the coating roll 1 and the support roll 2 made of metal. By doing so, durability can be improved, and the step 6 can be corrected to ensure uniform application. However, if the step 6 is too large, the panel frame 1 cannot pass through and stops, causing problems such as damage to the panel frame 1 and shortening of the life of the drive system of the device due to overload.

Therefore, the purpose of this invention is to provide an adhesive application device that can apply adhesive to the entire surface of the frame even if there is a step on the surface, and that has excellent durability. .

An embodiment of this invention is shown in FIG. That is, in this adhesive application device, the application roll 1 and the support roll 2 are made of metal. For example, the applicator roll 1 and the support roll 2 are plated iron rolls. The roll shaft 1a of the applicator roll 1 is urged toward the support roll 2 by a spring member 7.

In this way, the applicator roll 1 and the support roll 2
Since the panel frame 3 is made of metal, even if the panel frame 3 inserted between the rolls 1 and 2 has a step on its surface, it is strongly compressed between the rolls 1 and 2 and is straightened flat. Therefore, even if there are steps on the surface of the panel frame 3, the entire surface can be coated without leaving any uncoated areas. The straightening effect is well exhibited when the panel frame 3 is made of wood, but the straightening effect allows for good adhesive application regardless of the material of the panel frame 3. If there is a large level difference in the panel frame 3 that cannot be corrected, the applicator roll 1 rises against the spring member 7 to allow passage through the level difference. Therefore, damage to the panel frame 3 and overloading of the drive system of the device, which would shorten its lifespan, can be prevented. Further, since the applicator roll 1 and the support roll 2 are made of metal, they have strong abrasion resistance, and are about five times as durable as conventional rubber rolls. Therefore, maintenance is easy.

As mentioned above, the adhesive applicator of this invention is
Since the applicator roll and the support roll facing it are made of metal, even if there is a level difference on the surface of the frame, the level difference can be corrected by applying pressure while applying the coating. Adhesive can be applied to the entire surface without causing any scratches.
Moreover, it is highly durable and easy to maintain. In addition, since the application roll is supported movably in the direction away from the support roll and is provided with a spring member that biases the application roll toward the support roll, the frame can be easily moved when there is a large level difference that cannot be corrected. This has the effect of preventing damage to the frame and shortening of life due to overload of the drive system of the device.
