JPH07260349A - Method and apparatus for rotating object to be dried in drying room - Google Patents

Abstract

PURPOSE:To provide the subject method and apparatus wherein a number of objects to be dried can be rotated a desired angle at a time in a drying room, without requiring workers. CONSTITUTION:In a drying room 1 in which objets to be dried are placed on a conveyor 2 and are held, the objects each are placed adjacent to stoppers 3. When the conveyor 2 is allowed to slightly advance toward the stoppers 3 in such a situation, the objects are rotated on the conveyor 2 a desired angle. Therefore, it is unnecessary for workers to rotate the objects entering the drying room as usual.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for rotating a material to be dried in a drying chamber, which is used in a step of drying a cylindrical or cylindrical ceramic material extruded from a clay kneader. .

[0002]

2. Description of the Related Art A ceramic material extruded from a clay extruder is dried in a drying chamber until it has a hardness suitable for molding and processed into insulators. The materials to be dried such as the ceramic material are lined up and dried on the conveyor 2 provided inside the drying chamber 1 as shown in FIG. There is a problem that it accumulates on the side and conversely the upper side becomes too dry.
Therefore, conventionally, as shown in FIG. 3, an operator enters a drying chamber and manually rotates the object to be dried.

However, since a large-sized object reaches a weight of 100 kg, the work to be manually turned is a heavy work, and the work in a hot and humid drying chamber is not preferable in terms of working environment. There was a face.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the prior art, and allows a heavy object to be dried to be rotated at a desired angle in the drying chamber without requiring manual labor. The present invention has been completed to provide a method and an apparatus for turning a dried body.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a method for rotating a dried object according to the present invention is to place the dried object on a conveyor and store it in a drying chamber, and a stopper for the dried object. It is characterized in that the objects to be dried are rotated at a desired angle on the conveyor by adjoining them and slightly moving the conveyor toward the stopper in this state. Further, the object to be dried tumbling device of the present invention is provided with a conveyor for mounting a large number of objects to be dried inside the drying chamber, and a stopper for descending between the objects to be dried is provided on the ceiling of the drying chamber. It is characterized by that.

[0006]

According to the present invention, the stoppers are arranged adjacent to the respective objects to be dried, and the conveyor is slightly advanced toward the stoppers while the movement of the objects to be dried is prevented. It is possible to turn by the desired angle. For this reason, it is not necessary for an operator to turn a heavy object to be dried into the drying chamber as in the conventional case, the burden on the operator is reduced, and all the objects to be dried can be turned at the same time. Uniform drying is possible, and productivity can be improved.

[0007]

The present invention will be described below in more detail with reference to the illustrated embodiments. In FIGS. 1 and 2, 1 is a drying chamber similar to the conventional one, and 2 is a conveyor provided inside the drying chamber 1 in several stages. However, only one of them is shown in the drawing. In this embodiment, the conveyor 2 is a slat conveyor composed of a large number of plates, but other types of conveyors such as a roller conveyor may be used. This conveyor 2 is for mounting a large number of cylindrical objects to be dried on it. It should be noted that during the drying time, each object to be dried stays in its respective position on the conveyor 2 without advancing, and is advanced only when taking in and out.

Reference numeral 3 is a stopper provided on the ceiling of the drying chamber 1. As shown in FIG. 2, a gear 4 is fixed to the pivot portion of the upper end of the stopper 3, and a gear 5 meshing with the gear 4 is rotated by a motor 6, so that each stopper 3 is rotated around the gear 4. It can be rotated about 90 degrees like No. 2 and lowered between adjacent objects to be dried so that they can be adjacent or raised. Although a large number of motors 6 may be provided in the longitudinal direction of the drying chamber 1, it is preferable to use a connecting shaft as in the embodiment so that each stopper 3 can be simultaneously raised and lowered by one motor 6. .

The object to be dried tumbling device thus constructed has a large number of objects to be dried placed on the conveyor 2 and is dried. When the objects to be dried need to be turned, they are first dried. In the meantime, as shown in FIG. 1, the respective stoppers 3 are lowered so that the respective stoppers 3 are adjacent to the respective objects to be dried. When the conveyor 2 is advanced slightly toward the stopper 3 in this state, each object to be dried cannot be advanced by each stopper 3 and only the conveyor 2 moves, so that each object to be dried turns on the spot. Will be done. If the amount of advance of the conveyor 2 at this time is set to half the circumferential length of the object to be dried,
Each object to be dried is turned 180 degrees on the spot and turned upside down. In order to reliably perform such an operation, it is preferable that the stopper 3 extends to a position lower than the center of the body to be dried. Stopper 3
If the length is short, the surface of the object to be dried may be scratched.

After the turning of each material to be dried is completed, the stoppers 3 are raised to continue the drying, and after the completion of the drying, the conveyor 2 is advanced to dry the material to be dried from its end. Remove your body. At this time, since the stoppers 3 are raised, the forward movement of the material to be dried is not hindered.

[0011]

As described above, according to the present invention, the material to be dried on the conveyor can be surely turned at the desired angle at the same time without the operator entering the drying chamber. Therefore, not only is there an advantage that the labor of the worker is reduced, but since all the objects to be dried can be turned by the same angle, the dry state of each object to be dried can be correctly managed, It can also contribute to the improvement of productivity.
