Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for transferring a pattern to a ceramic molding. This pattern transfer device is suitable for use when transferring a pattern to a tile substrate.

[0002]

2. Description of the Related Art As a pattern transfer apparatus capable of transferring a pattern to a ceramic molded body, for example, when the ceramic molded body is a flat tile base material, a single pattern in which a completed pattern is engraved on a peripheral surface is used. Those having rollers may be used.

[0003] In this pattern transfer device, the roller is brought into contact with the design surface of the tile base at a predetermined contact pressure, and the roller is rotated relative to the tile base.
The completed pattern can be transferred to the design surface of the tile base.

[0004] By repeating such an operation, the same completed pattern can be transferred to a plurality of tile substrates while using a single roller.

[0005]

However, in the above-mentioned conventional pattern transfer device, as long as the same roller is used, only one pattern can be transferred to the ceramic molded body. For this reason, if another pattern is to be transferred to the ceramic molded body, a roller engraved with another pattern must be prepared. If many different patterns are to be transferred, one roller must be prepared for each pattern.

For this reason, if it is intended to obtain a plurality of types of ceramic molded bodies on which different patterns are transferred, the number of prepared rollers is increased even if the patterns are slightly different from each other. I will. If this is the case, it takes time to manufacture the rollers, increases the cost of manufacturing the rollers, increases the number of rollers to be stored, and makes it difficult to manage the patterns that can be transferred by these rollers. Management costs also increase. For this reason, the production cost for obtaining the ceramic molded body after the transfer is increased.

[0007] Further, after the ceramic molded body in which one pattern is transferred by the same roller is manufactured, the roller is not useful unless a ceramic molded body having the pattern is required. On the other hand, storing those rollers for future use, which may not be possible, also increases the administrative costs of the rollers.

[0008] These problems also occur when using means other than rollers. In particular, when transferring a pattern to a flat ceramic molded body such as a tile base material, a highly convenient roller is frequently used as a means for transferring the pattern. Also, since the roller for transferring the pattern to the flat ceramic molded body has to engrave the pattern on the peripheral surface that forms a cylindrical surface, compared to the case of engraving the pattern on a smooth surface, Roller labor and manufacturing costs tend to increase.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described conventional circumstances, and means capable of reusing the means and realizing a low-cost manufacturing method for obtaining a transferred ceramic molded body. It is an object of the present invention to provide a pattern transfer device for molding.

[0010]

The present inventor has focused on the fact that one pattern can be composed of a plurality of types of patterns.
The inventors have found that the above problem can be solved by this, and have completed the present invention.

The pattern transfer apparatus for transferring a pattern to a ceramic molded body according to the present invention is a pattern transfer apparatus for transferring a pattern to a ceramic molded body, wherein the first pattern constituting the pattern is transferred to the ceramic molded body. And a second means capable of transferring another type of second pattern constituting the pattern to the ceramic molded body.

In the pattern transfer apparatus of the present invention, a plurality of types of patterns such as a first pattern and a second pattern are selected to form a desired combination of means, and transfer is performed by the combination. Different finished patterns can be obtained. When another pattern is to be transferred to the ceramic molded body, the selected individual pattern may be changed to create another desired combination of means, and the transfer may be performed by the combination.

In this way, this pattern transfer device can transfer many different patterns to the ceramic molded body without preparing means capable of transferring each completed pattern. For this reason, since the increase in the number of means to be prepared can be suppressed, it is possible to reduce labor, manufacturing costs, and management costs of the means. For this reason, the manufacturing cost for obtaining the transferred ceramic molded body can be reduced. Further, each means can be selected and reused at the time of combination.

Therefore, according to the pattern transfer device of the present invention, the means can be reused, and the manufacturing cost for obtaining the transferred ceramic molded body can be reduced.

In the pattern transfer apparatus of the present invention, the effect is great when the ceramic molded body is a flat plate and the first means and the second means are rollers which come into contact with the design surface of the ceramic molded body. This is because the influence on the manufacturing cost of a flat ceramic molded body such as a tile base is great. In other words, if a roller is used, the length of the plate-shaped ceramic molded body does not matter in the direction orthogonal to the axis of the roller, and the pattern can be transferred to many types of ceramic molded bodies, and versatility can be improved. spread.

Preferably, a first pattern is engraved on the peripheral surface of the roller as the first means, and a second pattern is engraved on the peripheral surface of the roller as the second means. The effect of the present invention is great when the roller has to engrave a pattern on the peripheral surface forming a cylindrical surface.

In the pattern transfer device of the present invention, it is preferable that the contact pressure of the roller is adjustable. In this case,
It is possible to change the depth at which the convex portion of the peripheral surface that matches the pattern penetrates the ceramic molded body, and it is possible to transfer a different pattern to the ceramic molded body using the same roller. In addition, when abrasion occurs on the convex portion of the peripheral surface, by changing the distance between the convex portion and the ceramic molded body, the depth at which the convex portion bites into the ceramic molded body can be made constant, and the same can be obtained. The same pattern can be stably transferred to the ceramic molded body using the above rollers.

In the pattern transfer apparatus of the present invention, it is preferable that the roller as the first means and the roller as the second means are provided side by side in the direction of relative movement with respect to the ceramic molded body. In this case, a completed pattern can be transferred by a single relative movement with the ceramic molded body.

It is preferable that the pattern transfer device of the present invention has a conveying means capable of moving the design surface of the ceramic molded body in parallel. In such a case, the conveying means moves the ceramic molded body, whereby the completed pattern can be transferred to the design surface of the ceramic molded body. In this case, work efficiency is improved as compared with moving the roller itself with respect to the ceramic molded body. For example, when the roller itself is moved, the structure of the pattern transfer device is complicated, whereas when the ceramic molded body processed by a plurality of sheets is moved, the structure of the pattern transfer device is simplified. . In addition, if such a transport unit is provided, a drive unit for rotating the roller is not required, and the structure of the pattern transfer device is simplified. As such a conveying means, a belt conveyor can be employed.

In the case where the back surface of each design surface is made of a pair of two ceramic molded bodies, and a back surface of each design surface is brought into contact with each other, a pair of rollers for sandwiching both the design surfaces can be employed as the conveying means. This eliminates the need for a conveyor such as a belt conveyor, and can simultaneously process a pair of ceramic molded bodies, thereby improving work efficiency.

In the case where a groove extending to an edge in a direction perpendicular to the moving direction of the ceramic molded body is formed on the back surface of the design surface of the ceramic molded body, the pattern transfer device of the present invention employs a roller or a first means as a first means. The roller as the second means is preferably capable of pressing its edge. When the ceramic molded body is a tile base, for example, a backing is formed by forming a groove on the back surface of the design surface.
The tile as a product can be fixed to the wall by an adhesive present in the groove between the backing. When such a ceramic molded body is used, if the roller or the like as the first means can press the edge, a ceramic molded body in which the groove is crushed at the edge after the pattern is transferred can be obtained. . By firing the ceramic molded body thus obtained, a product having a groove whose edge is crushed on the back surface of the design surface can be obtained. If this product is a tile, the tile is less likely to have the adhesive existing in the groove protruding outward from the edge when applied to a wall surface, and is likely to exhibit an excellent appearance.

Further, the pattern transfer apparatus of the present invention preferably has a correcting means for correcting a displacement in a direction orthogonal to a moving direction of the ceramic molded body. In this case,
Since the correcting means corrects the displacement of the ceramic molded body in a direction orthogonal to the moving direction, the pattern of the obtained ceramic molded body does not vary, and a product of stable quality can be obtained.
