Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for transferring and feeding powdered or granular material, and more particularly, to transferring a container containing powdered or granular material to a material input port of a hopper by a transfer and loading device. The present invention relates to a method and apparatus for transferring and feeding a powdery or granular material for feeding the above material into a hopper.

[0002]

2. Description of the Related Art Conventionally, a container (hereinafter referred to as a pot) used for a method of transferring and injecting a powdery or granular material of this kind is provided with an opening / closing mechanism such as a damper at the bottom thereof. Then, after the pot is transferred to the input port of the hopper by the transfer and input device, the damper at the bottom of the pot is opened by the transfer and input device to input the granular material in the pot into the hopper, and when the input is completed, the damper is closed.

[0003]

However, if there is an opening / closing mechanism at the bottom of the container as in the prior art, the finer the particle size of the granular material, the more the granular material leaks from the opening / closing portion of the pot during transfer. There is a drawback that it is easy to do. Further, if the granular material adheres to the opening / closing portion, there is a drawback that the opening / closing failure is likely to occur and the input amount tends to be inaccurate.

Further, in the case of an apparatus for transferring and charging a container, the present situation is that no countermeasure is taken against the dust generated at the time of charging being scattered from the material charging port to the outside of the hopper. The present invention has been made in view of such circumstances, when the powder material is put into a container and transferred into a charging tank such as a hopper, it is possible to prevent leakage during transfer and dust generated at the time of charging. It is an object of the present invention to provide a method and apparatus for transferring and feeding a powdery or granular material capable of reliably charging the entire amount of the powdery or granular material in a container while preventing the powder from scattering outside the hopper.

[0005]

In order to achieve the above-mentioned object, the present invention provides a transfer charging method for transferring a powdery or granular material into a charging tank through a charging port of the charging tank. The container containing the granular material is transferred to the input tank by a container handling device, and then the container is loaded into the input tank and the container handling device is seated on the input port to close the input port. Next, the container handling device is used to invert the container and the powdery material in the container is charged into the charging tank.

[0006]

According to the present invention, the container containing the granular material is
The container handling device transfers the container to the charging tank and carries the container into the charging tank from the charging port of the charging tank, and the container handling device is seated on the charging port to close the charging port. Then, the container was turned upside down (the container was turned upside down) by the container handling device, and the powdery material in the container was put into the charging tank. That is, since the powdered or granular material in the container is charged by reversing the container, the powdered or granular material in the container can be surely charged in the charging tank, and like the conventional container. Since the opening / closing mechanism is not required at the bottom of the container, the granular material does not leak from the container during transfer. Further, since the container handling device closes the charging port of the charging tank at the time of charging, dust generated by charging does not scatter from the charging port to the outside of the charging tank. Further, by providing air jetting means in either one of the container handling device and the charging tank and blowing air into the inverted container, it is possible to surely charge all the granular material that is easily attached. . Further, since the collar is formed on the outer periphery of the central portion of the container, the container can be easily clamped and inverted.
