Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a holding structure for a tile body used when performing curtain glazing.

(Prior art) In the case of glazing on a curtain, glaze is made to flow down in a film shape like a curtain, and the tile body before firing (including that after firing) is passed through this glaze film to perform glaze. Is the way.
The glaze film is prepared by providing a can body that can temporarily store the glaze, and by providing a slit at the bottom of the can body (hereinafter,
This was called a glaze can). The glaze can was generally fixed on the transport path of the tile body, but recently, a method of performing curtain glazing by keeping the tile body in a stopped state and running the glaze can on the contrary is also available. Being developed.

(Problems to be solved by the invention) When the glaze film from the traveling glaze can comes into contact with the tile body in the stopped state, the glaze film is opposite to the traveling direction of the glaze can in the moment after the contact. It was refracted to the side, and at the next moment, the glaze traveled down the side of the tile body and went around to the back side. Therefore, surplus glaze was attached to the tile body after glazed from the side surface to the back surface.

By the way, although not shown in the drawings, the tile body after glazed is subsequently conveyed by a conveyor mechanism such as a belt conveyor or a roller conveyor to a roller hearth kiln (hereinafter, referred to as RH).
(K) and the like are carried into the firing furnace. However, if excess glaze is attached to the back surface of the tile body as described above, the excess glaze is transferred to the tile receiving surface (transport upper surface) of the transport mechanism to stain it, and is also provided in the RHK. It was designed to be fused to the transport roller. When the fused glaze gradually grew, the tile body meandered and became complicated in the RHK, and finally fell between the installation of the rollers and was damaged. In addition, even if the tile body (tile) escaped from falling, the surplus glaze on the back surface vitrifies it and loses its product value, causing it to stick to other tiles and rollers. . for that reason,
With various transfer mechanisms and RHK transfer rollers, the tile receiving surface must be cleaned frequently, which adversely affects the yield rate and firing efficiency of the entire firing process. there were.

Therefore, conventionally, after finishing the glaze application, it is necessary to perform a glaze finishing process to remove the adhered glaze on the back surface (and the peripheral side surface, etc.) of the tile body before firing. Was there. For this reason, in the transport mechanism and the like, the transport distance is lengthened, and the equipment is increased in size.

The present invention has been made in view of the above circumstances, and prevents the excess glazed from adhering to the tile element body, and occurs not only in the conveying step of the tile element body after glazing but also in the entire firing step. It is an object of the present invention to provide a new tile holding structure (hereinafter referred to as the main structure) for glazing for curtains, which can solve all of the conventional problems (those caused by adhesion of excess glaze) at once. .

[Constitution of device] (Means for solving the problem) The main point of the structure of the present invention is that the tile used for the curtain-glazed glazing that runs through the glaze can in the upper part of the tile body in the flat state. A holding structure for an element body, comprising a receiving cassette that holds and holds the back surface of the tile element body at least at its peripheral portion, and the receiving cassette intersects with the traveling glaze can first. The corresponding side is provided with a suction port for excess glaze directed to the upper edge of the tile body.

(Operation) Now, it is assumed that the glaze can comes into contact with the tile body held on the receiving cassette by the traveling of the glaze can. As described above, at this moment, the glaze film will be refracted to the side opposite to the traveling direction of the glaze can.
A suction port facing the upper edge of the tile body is provided. Therefore, the glaze film is directly recovered from the suction port. Therefore, there is no glaze on the back surface of the tile element body, and even if the tile element body is subsequently transported by various transport mechanisms or RHK transport rollers, etc. There is no risk of glaze being transferred to the surface.

(Embodiment) The present invention will be described below with reference to the drawings showing an embodiment thereof.

FIG. 1 is a side sectional view schematically showing the structure of the present invention. The structure of the present invention includes a receiving cassette 2 that receives and holds the tile body 1 in a flat state in a lower region of a glaze can 4 provided so as to be able to travel along an upper track 6. The receiving cassette 2 is formed in the shape of a quadrangular plate having a certain thickness, and its planar size is slightly larger than that of one tile element 1. On the upper surface of the receiving cassette 2, a plurality (for example, 4
Projections 3,3, ... are projected. The protrusions 3, 3, ...
The respective tile end portions support the tile element body 1, and the tile element body 1 is held so as to float above the upper surface of the receiving cassette 2 at least at the peripheral portion of the back surface thereof. The floating height is appropriate. The receiving cassette 2 has a hollow interior. It should be noted that a plurality of the receiving cassettes 2 are attached to the chain belt 7 that is installed in a direction orthogonal to the traveling direction of the glaze can 4 (see the white arrow) at a predetermined interval from each other. In this case, the chain belt 7 waits for the glaze can 4 to stop running and then performs an intermittent feeding operation according to the installation interval of the receiving cassettes 2, 2, .... ing.

The receiving cassette 2 is erected in such a manner that one side portion of the receiving cassette 2 which is crossed first when the glaze can 4 travels as indicated by a white arrow is bent. A suction port 5 is provided at the tip of the standing portion 2a facing the upper surface of the receiving cassette 2. The suction port 5 is formed by the protrusions 3, 3,
... The tile body 1 supported above is horizontally opened at a position slightly lower than the upper surface level thereof. However, it is also possible to provide a slight upward slope facing the upper edge of the tile body 1 or to horizontally open the same at the same height as the upper edge. Also, the suction port 5
Is an elongated opening shape along the lateral width direction of the glaze can 4 (the direction toward the back of the drawing), and the opening width along this direction is formed to have a dimension corresponding to one side length of the tile body 1. There is. For example, when one side length of the tile body 1 is 450 mm, the opening width of the suction port 5 is preferably around 400 to 500 mm. On the other hand, since the inside of the upright portion 2a of the receiving cassette 2 is formed in the same manner as the receiving cassette 2, the suction port 5 also has a communication relationship with the inside of the receiving cassette 2. Has become. The receiving cassette 2 is connected from its proper position to a suction device (not shown) that generates a negative pressure using a pump or the like. Therefore, the air around the upper surface of the tile body 1 held on the receiving cassette 2 can be strongly sucked from the suction port 5.

In the structure of the present invention thus configured, the receiving cassette 2
It is assumed that the glaze can 4 runs toward the tile body 1 held above in a direction in which the glaze can 4 approaches and intersects (see a white arrow). Then, it is assumed that the glaze film 4a formed from the glaze can 4 contacts the side surface 1a of the tile body 1. At this moment, the glaze film 4a is bent to the side opposite to the traveling direction of the glaze can 4, as shown in FIG. However, since the suction port 5 provided in the upright portion 2a of the receiving cassette 2 is positioned so as to face the side bent from the glaze film 4a, the glaze film 4a is directly recovered from the suction port 5. Will be done. That is, the glaze film 4a is formed on the side surface 1a before the side surface 1a of the tile body 1 tries to wrap around the back surface 1b.
The contact with 1a is cut off, and it does not adhere to the back surface 1b as excess glaze.

(Study of Another Mode) The receiving cassette 2 may be configured such that a plurality of tile bodies 1 can be placed flat along the traveling direction of the glaze can 4. In this case, it is important that each of the tile bodies 1 is closely attached to those having an adjacent relationship. However, as shown in FIG. 3, all parts of the receiving cassette 2 where the standing portions 2a, 2a are formed so as to partition the tile bodies 1 from each other and face the tile body 1. This is not the case if the suction ports 5, 5, ... Are provided.
With such a receiving cassette 2, the glaze can 4 can be made to travel back and forth, and the efficiency of glaze can be increased. Further, in providing the suction port 5, it is not necessary to purposely form the standing portion 2a. That is, if the suction port 5 is shaped like a nozzle to ensure its holding, the standing portion 2a can be omitted. Further, the suction device (not shown) that generates a suction force for the suction port 5 may be operated only when necessary, or may be always operated. As described above, the configuration and shape of the structure of the present invention can be appropriately changed according to the embodiment.

"Effect of Device" As is clear from the above description, according to the tile holding structure for hanging glazing according to the present invention, in the tile base body after glazed, excess glazed does not adhere to the back surface of the tile body. Therefore, there is no risk of glaze being transferred to the tile receiving surface (transport upper surface) such as the transport mechanism or the RHK transport roller.
This transcription glaze never grows. Therefore, in any case, the tile body is prevented from meandering or entanglement in the transportation state, and the tile body does not drop and be damaged from the tile receiving surface. Further, since these tile receiving surfaces are less likely to be contaminated by the excess glaze, the cleaning operation interval can be extended or made unnecessary. In this way, the yield rate and firing efficiency of the entire firing process can be improved. Further, since it is not necessary to intervene the glaze finishing step from the curtain glazing step to the firing step, the carrying distance of the carrying mechanism can be shortened, and the equipment can be downsized. It has a number of excellent advantages.
