BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for efficiently supplying an inlaid pattern raw material when forming an inlaid pattern on the surface of a ceramic product such as tiles.

[0002]

2. Description of the Related Art As one of tile decoration methods, there is an inlaid pattern. The inlay pattern is a state in which a pattern is embedded on the surface of the base material, in addition to a wet molding method in which a pattern or letters are engraved on the surface of the clay base and colored clay is poured or a color glaze is poured into it. There is also a method by dry pressure molding. In this method, a molding die is filled with a basic kneaded material which is a product base, and an inlaid pattern raw material such as a colored kneaded material is arranged at a required position on the surface of the basic kneaded material, and then the whole is pressure-molded.

[0003]

Since the process of forming the inlaid pattern by the wet molding method is almost done manually, the manufacturing cost is high, the productivity is low, and there is a problem in quality stability. . On the other hand, in the process using the dry molding method, the kneaded clay is easier to handle than the clay raw material for the wet process, and thus the potential productivity is considered to be high. However, in the past, the process of supplying the raw material for the inlay pattern to the surface of the basic kneaded material was a manual work, and the automation and mechanization of the manufacturing process was only partially achieved, so a sufficiently satisfactory production efficiency was obtained. Absent. That is, in the conventional process of supplying the inlaid pattern raw material, after filling the basic kneaded material as the product base into the molding die, a pattern paper having a through hole having a shape corresponding to the inlaid pattern is placed thereon, Is supplied from the upper surface of the pattern paper and dropped from the through hole onto the basic kneaded clay,
It was difficult to increase productivity because such a process was performed manually.

[0004]

According to the present invention, when forming an inlaid pattern on a tile or the like, a raw material for the inlaid pattern can be automatically supplied onto the basic kneaded clay, which dramatically improves the production efficiency. The present invention provides a device that can be operated, and is characterized in that the configuration is such that a hopper member that is installed in the vicinity of a molding die and stores the inlaid pattern raw material, and a raw material on the upper surface that is disposed below the hopper member. The raw material supply member is provided with a raw material accommodating portion having a receiving opening and a raw material delivery opening on the lower surface, and a shutter member for opening and closing the raw material delivery port of the raw material supply member. That is, it is possible to move substantially horizontally between the upper part of the molding space of the molding die and the outer position thereof while maintaining the state of facing the lower opening.

[0005]

The outline of the operating condition of the inlay pattern raw material supply device according to the present invention (hereinafter referred to as the "device of the present invention") will be described as follows. The device of the present invention is installed in the vicinity of the molding die, and in the standby state, the raw material supply member is located outside the molding space of the molding die. In this state, the basic kneaded material as the product base is supplied into the molding space of the molding die.

After the forming space is filled with the basic kneaded material, the raw material supply member is moved substantially horizontally to a predetermined position above the forming space. During this horizontal movement, since the lower opening of the hopper member maintains the state of facing the raw material supply member, when the raw material receiving port of the raw material supply member passes through the lower opening of the hopper member, the hopper member enters the raw material storage portion. Inlay material is supplied. Therefore, the raw material supply member is
When reaching the upper part of the molding space in the molding die, the raw material storage portion is filled with the inlaid pattern raw material.

Subsequently, the shutter member is operated to open the raw material delivery port on the lower surface of the raw material storage portion. As a result, the inlaid pattern raw material falls to a predetermined position on the surface of the basic kneaded clay.

Next, after the raw material supply member is horizontally moved to the original standby position, the basic kneaded material having the inlaid pattern raw material arranged on the surface thereof is pressure-molded by the molding die as described above, and is baked or the like. If necessary treatment is added, a product having a desired inlaid pattern can be obtained.
