Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a baking setter conveyed on a roller conveyor in a baking furnace.

[0002]

2. Description of the Related Art As a firing furnace used for firing an object to be fired such as ceramics, there is known a firing furnace such as a roller hearth kiln in which a roller conveyor is disposed in a firing furnace. In such a sintering furnace, a sintering setter is successively placed on the roller conveyor, and a sintering object is placed on each sintering setter and sintering is performed while the sintering object is conveyed. It has been known. As shown in FIGS. 11 and 12, the conventional firing setter 9 is a substantially square plate.

[0003]

However, the sintering setter 9 is a mere plate. For this reason, when the baking setter 9 is distorted or the movement of the roller conveyor 81 has a slight error, the pushing force of the roller conveyor 81 is applied to each baking setter 9.
Hard to apply evenly to the left and right. Therefore, the firing setter 9 may be shifted obliquely from the transport direction to the left and right.

[0004] As a result, the firing setter 9 collides with the guide 811 for preventing collision with the wall surface 82 of the firing furnace, or the vibration when the firing setters 9 collide with each other causes the object to be fired on the firing setter 9. 7 may be damaged.
When a large number of objects to be fired 7 are mounted on one setter 9 for firing, the mounting position is displaced due to the above-mentioned vibration, and the object 7 to be fired is deformed or adhered, resulting in defective products. May occur.

In order to solve this problem, a method is conceivable in which the firing setters 9 are placed on the roller conveyor 81 at a fixed distance L for each sheet so that the firing setters 9 do not collide with each other. In order to prevent the object 7 from being damaged even if it collides, the object 7 to be fired is placed within the range of the setter 9 for firing or the object to be fired placed on one setter 9 for firing. A method of reducing the number of the bodies 7 is also conceivable. However, in these cases, the space 80 in the firing furnace cannot be effectively used, and the production efficiency is reduced.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and prevents a baking setter from proceeding obliquely from a conveying direction, and effectively utilizes a space in a baking furnace to improve production efficiency. It is an object of the present invention to provide a sintering setter which can be used.

In this case, when placing the objects to be fired on these three firing setters, more objects to be fired can be stably mounted. Therefore, the production efficiency can be further improved by effectively utilizing the space in the firing furnace.

Next, according to a fourth aspect of the present invention, there is provided a baking setter which is conveyed on a roller conveyor provided in a baking furnace, wherein the baking setter is located on the roller conveyor in front of and behind it. It has a connecting tool for connecting the firing setter or the rear firing setter and the firing setter, and a connecting recess for connecting the connecting tool is provided at a front portion and a rear portion of the firing setter, respectively. The connecting tool is provided so as to be detachable from the connecting recess. When the connecting tool is mounted to the connecting recess, a plurality of firing setters connected by the two are substantially aligned. The firing setter is characterized in that the firing setter is configured to be lined up with.
