Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer device for transferring a hydraulic inorganic molded product from a molding machine to a curing storage.

[0002]

2. Description of the Related Art Conventionally, in general, a hydraulic inorganic molded product formed by a molding machine is placed on a receiving plate, and the receiving plate is transported from a forming machine to a curing storage by a chain conveyor, and is placed on the chain conveyor. The transfer of the receiving plate (direction change, elevating, lowering, pulling, pushing, etc.) is performed by an air cylinder which is normally performed at a constant speed. This transport device is convenient because it can transport the hydraulic inorganic molded product from the molding machine to the curing cabinet without using manual operation.

[0003]

However, the hydraulic inorganic molded product immediately after being molded by the molding machine is not cured but soft. Therefore, in the above-described transfer device, the transfer of the receiving plate on the chain conveyor (direction change,
Elevating, retracting, pushing, etc.)
At the start or stop of the operation such as lifting, lowering, pushing, etc., the hydraulic inorganic molded product on the receiving plate moves, or the shape (size of the product) of the hydraulic inorganic molded product changes slightly.
There is a problem that the surface is damaged. If the start and stop of the operation such as changing the direction of the air cylinder, ascending and descending, pulling in, pushing in, etc. are delayed so that the hydraulic inorganic molded product does not move, there is a problem that the working efficiency is reduced.

The object of the present invention has been made in view of the above problems. By using an air adjusting device of an air cylinder, a hydraulic inorganic molded product on a receiving plate does not move and does not change its shape. An object of the present invention is to provide a device for transporting a hydraulic inorganic molded article that does not damage the surface.

[0005]

Means for Solving the Problems The present invention has been made to achieve the above object, and the present invention comprises a conveyor with an air cylinder, in which a hydraulic inorganic molded product is placed on a receiving plate. In the conveyor for hydraulically molded inorganic material, the board is transported to a curing cabinet after being placed on a conveyor, an air adjusting device is attached to the air cylinder of the conveyor with an air cylinder. The operation at the time of the stop is freely and rapidly performed.

In the present invention, the material of the receiving plate of the hydraulic inorganic molded product may be any suitable material as long as the material has high rigidity. For example, stainless steel (SUS304) may be used.
Processing is possible, which is preferable.

In the present invention, the air adjusting device for the air cylinder may be any appropriate device as long as the air discharge and supply amounts can be adjusted. For example, a flow control valve with a check valve and a solenoid valve are attached to the air cylinder. This is preferable because the amount of air discharged and the amount of air supplied can be adjusted.

(Function) The present invention comprises a conveyor with an air cylinder, in which a hydraulic inorganic molded product is placed on a receiving plate, and the receiving plate is placed on the conveyor and transported to a curing cabinet. In the equipment, an air adjusting device is attached to the air cylinder of the conveyor with an air cylinder, and the operation at the start and stop of transport can be freely performed by the operation of the air adjusting device. By adjusting the speed, the speed at the start and stop of transport (direction change, lifting, lowering, pulling, pushing) is operated in three stages, so that the hydraulic inorganic molded product placed on the receiving plate does not move, The shape is not changed, and the surface can be prevented from being damaged.
