Description

  The present invention supplies powder, granular material, granular material, etc. (hereinafter collectively referred to as a powder) from the supply unit to the receiving unit in a determined amount without causing contamination (contamination). The present invention relates to a supply method and a supply device.

In a wide range of industrial fields that handle foods, pharmaceuticals, chemicals, etc., many types of powders are used as raw materials for manufacturing products.
For example, the powder is shipped from the manufacturer in a sealed state in a bag of paper, cloth, etc., and the contractor using the powder contains the powder in a container such as a container or a hopper. The required amount is transferred from this container to other containers according to the situation.

  Normally, the necessary amount of powder is transferred from the supply unit side container to the container, hopper or other appropriate receiving unit side container, and it is transported to the specified location, but when transferring from the supply unit to the receiving unit, A chute is used in between, and a chute is used to form a granule input path and to prevent generation of dust.

For example, in the technique disclosed in Japanese Patent Application Laid-Open No. 11-348902, a chute for charging granular material such as an upper chute 34, a lower chute 35 and a charging chute 39 is installed between the granular material supply container 11 and the bag 14. These chutes form a powder channel.
JP 11-348902 A

  If the supply of the granular material is repeatedly performed through the chute, the granular material adheres to the inner wall surface of the chute little by little. Therefore, it is necessary to replace or clean the chute periodically or as necessary. In particular, when supplying multiple types of granular materials with different contents to one receiving container, it is necessary to replace the chute or clean the chute each time. If neglected, foreign particles were mixed and a contamination phenomenon occurred.

  In order to replace or clean the chute, it is necessary to remove the chute from the supply container or the receiving container, or to attach a new chute to the supply container or the receiving container. It was a big one. Further, when the chute is removed, dust is generated and the surroundings are soiled, and the worker may inhale the powder and harm the health.

Is separated to enable supply of powder. In addition, it has a conical discharge part at the bottom of the body part, and a discharge port that can be opened and closed is formed in the discharge part. The lower support is separated from the container that can be erected by the lower support, and placed in a hollow position. A container that can be placed is used as a powder supply unit, and a receiving container having an inlet is used as a powder supply unit, so that the supply of powder from the supply unit to the receiving unit can be performed directly. The receiving container can be raised and lowered to the supply container by an elevating device that holds the measuring instrument.

  According to the method and apparatus for supplying powder of the present invention, the entire container is usually erected, the lower support used for storage and transport can be separated from the container body, and the valve at the lower end of the discharge part is exposed. Therefore, the container for separating the lower support is held in a hollow position to form the powder supply unit, the container for receiving the powder is placed at a predetermined position, and the container outlet It is possible to supply a determined value while measuring by directly connecting the inlet of the receiving container and the inlet of the receiving container. And after supply of a granular material, a supply side container can be erected by connecting a lower support stand and an upper support stand.
