Description

Adhesive Feeder for Bending Machine {Apparatus for providing a bonding agent of a banding machine}

The present invention relates to an adhesive supply apparatus for a banding machine, and more particularly, to an adhesive supply apparatus for a banding machine capable of uniformly supplying an adhesive to a long width band for attaching along a surface of a panel.

Panel products have a poor appearance because the cut surface of the material is exposed when the plane or side is cut. Therefore, the decorative band is adhered to the plane and the side of the panel, and the remaining part of the band is cut to finish the decoration. The equipment used for this task is commonly referred to as a banding device. Here, the banding device is divided into an edge banding machine for finishing the side border of the panel and a banding machine for finishing the decoration along the surface of the panel.

The adhesive supply device used in the conventional banding device generally adopts a method of applying adhesive to the surface edge of the panel. In the case of a thin band and a wide band, there is a limit in applying the adhesive to the surface edge of the panel for banding. . On the other hand, when bending along the surface of the panel had a disadvantage that it is difficult to uniformly apply the adhesive on the surface of the panel.

Therefore, the present invention improves the problem of the adhesive supply device of the existing banding machine, so that even when the band is thin and wide, the band can be smoothed, and the adhesive can be uniformly applied between the panel and the band. It is an object of the present invention to provide an adhesive supply of a bending machine.

In order to achieve the above object, the present invention provides an adhesive container having a supply passage and a return passage formed at a lower portion thereof, and inserted into the supply passage and disposed in a horizontal direction with respect to the adhesive container, and a transfer screw and an application roll on a circumferential surface thereof. A housing provided with an adhesive control shaft and an adhesive passage, each provided with an application rotating shaft, fixed to the adhesive container while covering the lower portion of the application roll of the application rotating shaft, and having a uniform thickness of the adhesive on the application roll; It is inserted into the passage vertically disposed with respect to the adhesive container and provided with a conveying screw on the circumferential surface includes a return rotation shaft for transferring the adhesive entering the return path toward the adhesive container.

According to the adhesive supply apparatus of the banding machine according to the present invention, the adhesive flowed into the supply passage as the coating rotation axis is rotated to the application roll by the transfer screw, while the adhesive supplied to the band roll by the adhesive control shaft It is scraped and returned to the inside of the adhesive container along the conveying screw of the return rotation shaft which rotates through the adhesive passage of the housing and the return passage of the adhesive container, thereby uniformly applying the adhesive to the surface of the band while preventing waste of the adhesive. .

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

1 is a perspective view illustrating an adhesive supply apparatus of a banding machine according to the present invention, and FIGS. 2, 3, and 4 are cross-sectional views illustrating lines A-A, B-B, and C-C of FIG. 1, respectively.

1 and 2, the adhesive supply apparatus according to the present invention, an adhesive container 10 having a supply passage 12 and a return passage 14, and a supply passage of the adhesive container 10 ( 12, the coating rotating shaft 18, which is provided in the circumferential surface and has a feed screw 18a and a coating roll 18b, respectively, and an adhesive on the coating roll 18b of the coating rotating shaft 18, has a uniform thickness. A housing 20 having an adhesive adjusting shaft 22 and an adhesive passage 24 made of a resin, and a return rotating shaft for transferring the adhesive entering the return passage 14 of the adhesive container 10 toward the adhesive container 10. It is comprised including 24.

As shown in FIG. 2, the adhesive container 10 has a supply passage 12 and a return passage 14 formed therethrough under the adhesive. The supply passage 12 is the outlet 12a is opened to the adhesive portion is stored to the adhesive is supplied, while the supply passage 14 is formed to cross the supply passage 12 while the adhesive container 10 of the Inlet 14a is drilled through one side wall. On the other hand, the adhesive container 10 is formed with a heating portion 16 on one side wall to heat the adhesive in the container.

2 and 3, the application rotating shaft 18 is inserted into the supply passage 12 of the adhesive container 10 is disposed in the horizontal direction in the container. Then, the application rotating shaft 18 is provided with a transfer screw 18a and an application roll 18b on the circumferential surface, respectively, where the portion where the transfer screw 18a is formed is inserted into the supply passage 12, while the application is applied. The part in which the roll 18b was formed is inserted in the housing 20. Here, the application rotating shaft 18 serves to transfer the adhesive filled in the supply passage 12 of the adhesive container 10 to the application portion of the housing 20 as the shaft rotates.

As shown in Figure 2 and 3, the housing 20 is fixed to the adhesive container 10 so that the upper portion of the application roll (18b) is opened, the adhesive passage 20a is formed in the longitudinal direction Thus, the adhesive that is scratched on the adhesive control shaft 22 is filled. Here, the adhesive passage 20a of the housing 20 communicates with the inlet 14a of the return passage 14. The housing 20 is provided with an adhesive adjusting shaft 22 disposed in parallel with the application roll 18b to make the adhesive adhered to the roll to a uniform thickness. Here, the adhesive control shaft 22 is rotatably installed in the housing 30 and a part of the adhesive control shaft 22 is faced along the axial direction to form a flat portion. Therefore, the tip of the planar portion of the adhesive control shaft 22 maintains a constant distance from the application roll 18b of the rotation shaft 18 so that the adhesive is always maintained at a uniform thickness on the application roll 18b.

As shown in FIG. 4, the return rotation shaft 24 is inserted into the return passage 14 of the adhesive container 10 so as to be vertically disposed with respect to the container, and the return screw 24a is provided on the circumferential surface thereof. The adhesive entering the passage 14 is transferred to the adhesive container 10.

Referring to Figure 2 to Figure 4 of the adhesive supply device of the banding machine according to the present invention, the supply passage 12 as the application rotating shaft 18 inserted in the supply passage 12 of the adhesive container 10 rotates The adhesive entering the outlet 12a of the is moved to the application roll 18b through the transfer screw 18a. Thereafter, the adhesive applied to the band in the application roll 18b and remaining or oversupplied is scratched by the adhesive adjusting shaft 22 of the housing 20 and then returned to the return passage 14 via the adhesive passage 20a and the inlet 14a. Will flow into. Thereafter, as the return rotation shaft 24 inserted into the return passage 14 rotates, the adhesive filled in the return passage 14 returns to the adhesive container 10 along the transfer screw 24a. Of course, when the application rotation shaft 18 and the return rotation shaft 24 rotates, the adhesive is sequentially transported by the pressure acting in the supply passage 12 and the return passage 14.

According to the adhesive supply apparatus of the banding machine according to the present invention as described above, unlike the conventional, the application roll of the application rotating shaft is arranged in the horizontal direction so that the band enters into a horizontal state to uniformly apply the adhesive to the band surface On the other hand, the excess adhesive supplied to the application roll is to be returned to the adhesive container to reduce the waste adhesive. And, the adhesive supply device of the banding machine of the present invention is configured to apply the adhesive to the band, unlike the method of supplying the adhesive to the panel in the existing banding machine to prevent the coating failure even when using a thin and wide band.
