JPH06269724A - Method and device for continuously applying glass beads granular particles - Google Patents

Abstract

PURPOSE:To provide a continuous applying method by which glass beads granular particles are continuously and uniformly applied to a lengthy member 4 and where the required space is small and productivity is high by making the flow rate at the outlet of granular particles in an inclined passage lower than that in a vertical passage to continuously stick and fix the granular particles to the lengthy member. CONSTITUTION:In a method of continuously applying glass beads granular particle 1, while lengthy member 4 to which the glass beads granular particles 1 are to be stuck in an exposed state is transferred at a prescribed speed in the longitudinal direction, the glass beads granular particles 1 are made to fall from above the lengthy member 4 during its transfer to continuously stick and fix them to it. At this time, since the flow velocity in an inclined passage R2 for the glass beads granular particles 1 is made lower than that in a vertical passage R1, the contact time to the lengthy member 4 is long to obtain the time required for sufficient sticking, allowing the uniform laminated application to be obtained even if the lengthy member 4 moves at a relatively low speed. Thereby, while utilizing the natural falling of the glass beads granular particles 1, the uniform application is made with good productivity even for a small space.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous coating method for glass bead powder and a coating apparatus therefor, and more specifically, it continuously forms exposed laminated glass bead powder on the surface of a long plate material. TECHNICAL FIELD The present invention relates to a continuous coating method for glass beads powder and a coating device for use in various applications.

[0002]

2. Description of the Related Art Conventionally, glass bead powder coated plates used for various purposes such as design and decoration have been manufactured by various methods. For example, the required glass bead powder or granules, for example, inorganic glass spheres alone or mixed with small pieces or granules of metal, ceramic, plastic, natural stone, etc., in the state where an adhesive is applied to the surface of the substrate material. Apply by spraying or spraying from above,
The method of fixing is adopted.

[0003]

However, such a coating method of glass bead particles such as spraying or spraying has a problem that it is difficult to adjust the spraying pressure, and uneven coating is likely to occur. If you want to apply on both sides or the whole surface,
There is also a problem that the substrate material has to be turned upside down or inverted and moved so that it is uniformly applied to the entire surface, regardless of the spraying method or the spraying method from above. Further, there is also a problem that the size of the recovery device is increased in order to prevent scattering of the glass bead powder particles due to spraying. In particular, a general substrate is a long plate material, and if necessary, cut into a predetermined size for use,
When applying the glass bead powder, it is necessary to spray or spray along the longitudinal direction of the long plate material, not only the space for spraying or spraying becomes wider, but also while moving. In spraying or spraying, it was difficult for even an extremely skilled person to apply a uniform coating. In addition, there was a problem that productivity could not be improved by such spraying and spraying.

Therefore, research was repeated on the spraying method from above, which is the simplest application method, and an attempt was made to transfer a long plate material while spraying from above. According to this method, since the spraying position is a fixed position, the spraying space can be small, and spontaneous fall can be used. Therefore, there is an advantage that no special power source such as spraying is required. However, when actually performing this method, even if the long plate material was simply moved in the lateral direction at a predetermined speed while the glass bead granules were naturally falling from above, uniform coating could be obtained. I couldn't do it. As a result of further research on this problem, it was found that the transfer rate of the long plate material needs to be significantly reduced because the natural falling speed of the glass bead powder particles is too fast for uniform coating. However, if such a solution is taken, there is a new problem that productivity becomes extremely poor. In view of the problems of the prior art, the present invention, when applied to the substrate material of the glass beads powder, can be applied continuously and uniformly to a long plate material, and the required space is small. It is an object of the present invention to provide a continuous coating method of glass bead powder and granules with high productivity and a coating apparatus therefor.

[0005]

In order to achieve the above object, a continuous coating method for glass bead powder or granules according to the present invention provides an adhesive agent to a long plate material for adhering the glass bead powder or granules in an exposed state. Apply, transfer the long plate material in the longitudinal direction at a predetermined speed, and let the glass bead particles fall from the upper part of the long plate material during the transfer at a predetermined speed into the drop path, and the drop path, A vertical flow path and at least one inclined flow path that is directed diagonally downwardly thereafter, and the outlet flow velocity of the glass bead powder is set to be slower than the flow velocity in the vertical flow passage. A means of continuously adhering and fixing the glass bead powder particles to the long plate material was taken.
In addition, it is preferable that the long plate material is formed in a shape that promotes the flow of the glass bead powder or granular material, or is transferred in a direction that promotes the flow of the glass bead powder or granular material.

In order to achieve the above object, the continuous coating device for glass bead powder or granules according to the present invention is provided with an upper hopper for accommodating the glass bead powder or granules, and the glass is provided below the upper hopper. Provided is a main body frame that constitutes a vertical flow path for allowing the bead powder to fall naturally, and a transfer means for transferring a long plate material that adheres the glass bead powder in an exposed state so as to be orthogonal to the vertical flow path. Provided in the main body frame is an inlet opening for taking in the long plate material and an outlet opening for taking it out, and in the vertical flow path between the long plate material in the main body frame and the main body frame. A subsequent inclined channel is formed, and the cross-sectional area of the lower portion of the inclined channel is smaller than that of the upper portion of the inclined channel so that the flow rate of the glass bead powder in the inclined channel becomes slower than the flow rate of the vertical channel. Configure to be smaller It took measures that. A lower hopper that collects the glass bead powder and granules from the inclined flow channel is preferably provided below the main body frame. Further, it is preferable that the inlet opening and the outlet opening of the main body frame are formed in a shape that substantially matches the cross-sectional shape of the long plate material passing therethrough. Further, it is preferable that the transfer means is composed of a belt conveyor, and the belt conveyor is composed of a feeding conveyor and a receiving conveyor, and both conveyors are operated in conjunction with each other.

[0007]

According to the method of the present invention, while the long plate material for adhering the glass bead powder particles in the exposed state is transferred at a predetermined speed in the longitudinal direction, the glass bead powder is fed from above the long plate material during the transfer. The granules are dropped at a predetermined speed, and the glass bead powder granules are continuously adhered and fixed to the long plate material. At that time, since the flow velocity of the glass bead particles in the inclined flow channel is slower than the vertical flow velocity, the contact time with the long plate material becomes longer, and sufficient bonding time can be obtained. It is possible to obtain a uniform layered coating even when moving rapidly. Therefore, uniform application can be performed with good productivity even in a narrow space while utilizing the natural fall of the glass bead particles.

In the coating apparatus according to the present invention, a slanted channel continuing from the vertical channel is formed between the long plate member in the body frame and the body frame, and the glass bead powder in the slanted channel is formed. Since the cross-sectional area of the lower part of the inclined flow passage is smaller than that of the upper part of the inclined flow passage so that the flow velocity of the granules becomes slower than the flow velocity of the vertical flow passage, a high-speed spontaneous fall is achieved. While utilizing, it is possible to reduce the surface flow-down speed for the long plate material, by this, the contact time to the long plate material becomes long, sufficient adhesion time is obtained,
This enabled uniform layer coating without significantly reducing the transfer rate of long plate materials. And, although the inclined flow path to be applied is formed by the long plate material itself to be applied and the main body frame and the continuous application is performed along the longitudinal direction of the long plate material, its structure is extremely It's easy. It should be noted that the transfer speed of the transfer means increases when the width (length in the transfer direction) of the main body frame is increased, and when it is decreased, the transfer speed is reduced to a relatively slow speed. It is self-explanatory, and may be implemented by appropriately responding.
