Description

[Detailed Description of the Invention] The present invention relates to an apparatus for applying glue to a veneer, and more specifically, to an apparatus for applying glue to a veneer being conveyed on a conveyor.

In general, veneers such as sliced veneers are thin, so if you glue them with a conventional spreader, the veneer may get wrapped around the rubber roll during transportation, and especially if there are cracks along the fiber direction, it may break. There was a problem in that the parts were wrapped tightly around the rubber roll, causing cracks to fully expand.

The present invention has been made in view of the above points, and its main purpose is to provide an apparatus for applying glue to a veneer in which the veneer does not wrap around the roll that applies glue to the veneer.

The present invention will be explained in detail below based on embodiments shown in the figures.

The apparatus for applying glue to a veneer according to the present invention includes a vacuum conveyor 2 that adsorbs a veneer 1 to its upper surface under atmospheric pressure and conveys it in one direction, and a vacuum conveyor 2 that transfers the outer circumferential surface of the veneer 1 onto the upper surface of the veneer 1 on the vacuum conveyor 2. A cylindrical mesh belt 3 that rotates in contact with the
An application roll 4 coats the top surface of the veneer 1 through the mesh of the mesh belt 3 by rotating while inscribed in the inner peripheral surface of the mesh belt 3, and an application roll 4 disposed within the mesh belt 3 to supply glue to the outer periphery of the application roll 4. A glue supply means 5 is provided inside the mesh belt 3 in order to separate from the mesh belt 3 the projecting plate 1 which is about to adhere to the outer periphery of the mesh belt 3 by blowing air out of the mesh belt 3 through the mesh from the mesh belt 3. In this embodiment, the glue supply means 5 is
Using a doctor roll that sequentially supplies the glue 10 held between the outer periphery of the application roll 4 to the application roll 4, the application roll 4 and the doctor roll 5 and a nozzle 6 are arranged.

The veneer 1 has a slit 12 from the first vacuum conveyor 2a.
During the transfer to the second vacuum conveyor 2b that is lined up with the first vacuum conveyor 2a, it is sandwiched between the feed roll 13 provided below the slit 12 and the coating roll 4, and is coated on the entire upper surface. Gluing is performed by the applicator roll 4 over the entire area.

The veneer 1 to which glue is applied with the applicator roll 4 is then
The second vacuum conveyor 2b is pressed tightly by the compressed air ejected from the nozzle 6, and is transported to the next process without adhering to the net belt 4, where it is bonded to the surface of a substrate (not shown).

Since the present invention has the above-mentioned configuration, the glued veneer can be transported by adsorption onto the vacuum conveyor without getting wrapped around the mesh belt by the air ejected from the nozzle in the mesh belt, unlike the conventional method. There is an advantage that the veneer after pasting does not get wrapped around the roll for gluing, and even if there is a crack in the fiber direction, the cracked part can be prevented from adhering to the mesh belt.
