Abstract

PURPOSE:To develop a multilayer coating spreader capable of replenishing a paint simply, in the multilayer coating spreader, by a method wherein a coating roll is constituted from a large diameter coating surface and a small diameter non-coating surface and a paint sump is formed by the coating roll, a doctor roll and a paint stopping plate. CONSTITUTION:Above a wide sending roll 10 for sending a plate 11 to be painted, a coating roll 12 and a doctor roll 13 are parallelly provided. The coating roll 12 is alternately equipped with large diameter coating surfaces 12a and small diameter non-coating surfaces 12b and attached to a rotary shaft 14. The doctor roll 13 is constituted by alternately attaching a large diameter parts 13a and a small diameter parts 13b bitten with the coating roll 12 to a rotary shaft 15. In addition, paint stopping plates 16 are provided to the end surfaces of both ends of the coating roll 12 and the doctor 13 and a paint sump is formed between both rolls 12, 13. The replenishing of a paint 17 can be simply carried out at one place as well as only two paint stopping plates 16 are used and the overall structure is made extremely simple.

Description

[Detailed description of the invention] This invention relates to multicoat spreaders.

Conventionally 1. When manufacturing artificial decorative veneer T-, material veneers coated with lI are laminated to form a flitch, and this flitch is sliced with a slice plane that intersects the laminated surface to obtain a decorative veneer with a wood grain pattern. When painting the veneer of the above-mentioned material, it is coated with two or more types of paint in stripes in order to express the wood grain pattern well. 11), conventionally the spreaders shown in FIGS. 1 and 12 have been used. In other words, two spreaders 1.2 are installed adjacent to each other in the feed direction AK of the object.

These spreaders 1 and 2 are connected to one wide feed seal 3.
, coating rolls 4 woven at regular intervals above the feed seal 3, doctor rolls 5 contacting each coating roll 4, and each coating roll 4 and doctor meal 5 being sandwiched from both sides. Each of the coating rolls 4 and the doctor roll 5 are connected to the coating rolls 4 of the two spreaders 1.2, each of which is mounted on a rotary shaft 7°8, and a paint stop plate 6 forming a paint reservoir. The positions are shifted from each other in the width direction, and due to the spreader l of J[1, jl! A striped pattern of the first paint is applied, and the unpainted areas are painted with the second paint by the second spreader 2. However, in the spreader 1.2 of 1M1 and N2,
Since it is necessary to replenish the paint reservoir with paint for each coating cycle 4, there is a problem in that replenishing the paint takes a lot of time and effort.

However, since two paint stopper plates 6 are provided for each coating roll, there is a problem in that the structure is complicated.

Therefore, an object of the present invention is to provide a multi-layer m-system ladder that can be refilled at one place and has a simple structure.

One embodiment of the invention is shown in FIGS. 3 and 4. In the figure, 10 is a wide feed roll for feeding the plate 11 to be coated, and a coating roll 12 and a doctor roll 13 are placed on top of it.
The 0 coating a-rule 12, which is arranged in parallel with
2m and a small diameter non-coating surface 12b alternately, one rotating shaft 1
They were defeated by 4. The doctor roll 13 has alternating large-diameter portions 13m and small-diameter portions 13b that mesh with and substantially roll into contact with the coating roll 12, and is attached to a rotating shaft 15.

Application roll 12 and doctor roll 130 rotating shaft 14
．． 15 is connected to a rotary drive device. Application roll 1
There is a paint stopper plate 1 between the ends of 2 and doctor row 13.
6 are brought into contact with each other, and a groove-shaped paint reservoir is formed between the paint stopper plate 16 and the surface of the paint stopper plate 16. Coating surface 12a of coating roll 12
and the gap d1 between the doctor roll 13 and the gap d2 between the non-coating surface 12b of the coating roll 12 and the doctor roll 13 and I/i.

d engineering < d2. Note that two of these spreaders are arranged side by side in the feeding direction K11 of the object to be coated, similar to the example shown in FIG.

By storing the paint 17 in the paint reservoir between the coating roll 12 and the top surface of the doctor roll 13 between the paint stop plates 16 at both ends of the corner 1 constructed as described above, and feeding the object 11 to be painted, Striped Vcj only on the large diameter coating surface 12m of the coating roll 12 on the object 11! The outfit will be carried out. Therefore, you only need to replenish the paint in one place,
This spreads the paint over the entire coating surface 12a of the coating roll 12, making it easier to replenish the paint. By the way, since only two paint stop plates 16 need to be provided at both ends, the number of parts is small and the structure is simple.

As described above, the multi-layer sysplay ladder of the present invention includes a coating roll that is installed approximately parallel to each other and has alternating large-diameter coated surfaces and small-diameter non-coated surfaces; The coating a has alternating portions and small diameter portions.
- Since it is equipped with a doctor roll that forms a groove-shaped paint reservoir between the roller and the surface of the roller, and a paint stopper that closes both ends of the groove-shaped paint reservoir, the paint can be replenished from one place. It is easy to replenish paint, and the structure is simple as there are fewer paint stoppers.
