Abstract

PURPOSE:To improve adhesion of a masking form to a base plate to ensure spraying of a coating material by a method wherein a stopper is provided in the center of the front end of the masking form, the rear surface of the masking form is reinforced by square bars at the both sides thereof, and right and left fixing springs are symmetrically installed inside the reinforcing square bars. CONSTITUTION:A base plate 3 is placed on a belt conveyor 1. Thereon, a masking form 11 is placed. Since the width of the belt 1 is determined to be smaller than the width of the base plate 3, the masking plate 11 is surely placed. On the both sides of the masking form 11, reinforcing materials consisting of square bars 12, 13 are securely fixed. Base plate holding springs 15 are mounted inside the reinforcing materials 12, 13. In this construction, the base plate 3 can surely adhere to the masking form 11 without a possibility that the masking form may be folded. Thus, a color coating can be completely applied to a tile.

2. Description of the Related Art Conventionally, a mask mold is put on a colored original plate, a tile pattern color paint is poured on the master plate, the paint is penetrated into every corner by vibration, and the mask mold is filled. On the left and right side, there was a spring fixture attached to the original plate. The mask mold was not reinforced.

[0003]

When the tile color paint is filled by the conventional vibration, the paint leaches out to the joint layer of another color, resulting in a defective product. In addition, since the mask type has many punching and solidification points and is too thin, it often bends or folds, and stacking them causes the metal fittings of the device holding the lower original plate to collapse or become deformed and become unusable. It often happened.

[0004]

To solve this problem, first, the mask die must be strong and have a strong holding force for the original plate and be easy to handle. In that case, a tile pattern printing device suitable for this mask type is required.

As the method, the method described in claim 1 is used. First, as an example, in order to reduce vibration, a belt conveyor is used instead of a roller conveyor. This will be described with reference to the attached drawings. This conveyor (1) is a little narrower. It is divided into two parts, a base point part (18) and a working part (19), the base part advances intermittently, and the working part always advances at a constant speed. On the working part there is a pressure roll (6) (7) first coating machine (8) second spray coating machine (10) and then various devices for surface finishing, and finally to a stacking machine. Continue.

As shown in FIG. 2, in the mask type, wood, metal, or plastic angle members (12, 13) for reinforcement are fixed on both sides at intervals slightly wider than the width of the original plate. An original plate holding spring made of a leaf spring or the like is attached. The size of the reinforcing material differs depending on the material, but the height is higher than the thickness of the original plate so that it can be easily accumulated.

[0007]

[Operation] With the structure as described above, the original plate is first placed on the belt at the base point portion (18) of the conveyor belt, and then the mask die is placed. These materials are collected separately on the left and right sides of the belt. It is placed at an accurate position (relationship between the original plate (3) and the mask die (11) shown in the figure) by the installed ruler. Then, the conveyor belt advances and the material enters the pressure bonding roll (6), but at that time, the substrate portion is fast-forwarded so as to catch up with the previous material and continuously enter the pressure bonding roll. Then, the mask mold is crimped by the crimping roll (6),
As shown in FIG. 5, it adheres to the original plate. This is because the belt width is narrow and the reinforcing material on both sides of the mask die can go down to below the belt.

Next, while the mask die is being pressed by the roll (7), a joint color paint having the same color as the original plate is sprayed from the first spray coating machine (8) so that a gap between the original plate and the mask die is formed. Fill in. Next, a paint of a predetermined tile color different from the joint color is sprayed on the mask mold by a second spray coating machine to a predetermined thickness, and the process proceeds to the surface treatment step, and is accumulated at the end of the line. It There may be one or more second spray coating machines. The paint referred to here is mainly a cement-based material.

[0009]

[Effect] In the mask type, since reinforcing materials are attached on both sides, it is less likely to bend and the spring for holding can be attached securely. Therefore, the original plate and the mask type are in close contact with each other. It is also easy to integrate as it is because the lower surface of the mask-type reinforcing material overlaps the upper surface of the mask-type. Also, in the equipment, since the width of the conveyor belt is a little narrower than the original plate, the original plate and the mask type are in close contact, and since the spray coating machine is also installed for the joints, the joint color paint is not the gap between the mask type and the original plate. It is possible to make beautiful and complete products without the tile color paint sprayed with the second coating machine to fill the joints and to prevent the joints from getting dented.
