Abstract

Provided is a particulate matter filling method for measuring the volume of particulate matter and filling the particulate matter into a container, the method being able to improve the performance of a facility while maintaining high quality measurement accuracy. This method includes: moving a first particulate matter fed through a feeding section to a first measuring section; moving a second particulate matter fed through the feeding section to a second measuring section and measuring the first particulate matter; moving the first particulate matter to a first filling section and measuring the second particulate matter; filling the first particulate matter, and then moving the second particulate matter to a second filling section; and filling the second particulate matter.

First claim

The invention claimed is:

1 . A particulate matter filling method for measuring a volume of particulate matter and filling the particulate matter into a container,
wherein a feeding section that feeds the particulate matter, a first measuring section and a first filling section disposed in a stated order toward one side with respect to the feeding section, and a second measuring section and a second filling section disposed in a stated order toward another side with respect to the feeding section are provided, the first measuring section and the second measuring section performing a measuring operation of modifying the volume of the fed particulate matter to a desired volume by leveling, and the first filling section and the second filling section performing a filling operation of introducing the particulate matter modified to have the desired volume into the container, the particulate matter filling method comprising: moving first particulate matter fed through the feeding section to the first measuring section toward the one side; moving second particulate matter fed through the feeding section to the second measuring section toward the another side and performing the measuring operation on the first particulate matter moved to the first measuring section; moving the first particulate matter modified to have a desired volume by the measuring operation to the first filling section toward the one side and performing the measuring operation on the second particulate matter moved to the second measuring section; performing the filling operation on the first particulate matter moved to the first filling section, and then moving the second particulate matter modified to have a desired volume by the measuring operation to the second filling section toward the another side; and performing the filling operation on the second particulate matter moved to the second filling section.

2 . The particulate matter filling method according to claim 1 , wherein during the moving of the second particulate to the second measuring section and during the moving of the first particulate matter to the first filling section, the measuring operation is performed by leveling the fed particulate matter in a compressed state.

3 . The particulate matter filling method according to claim 2 , wherein the particulate matter is a desiccant and/or an oxygen absorber.

4 . The particulate matter filling method according to claim 1 , wherein the particulate matter is a desiccant and/or an oxygen absorber.

5 . A particulate matter filling device that measures a volume of particulate matter and fills the particulate matter into a container, the particulate matter filling device comprising:
a fixed vessel plate disposed horizontally; a movable vessel plate disposed horizontally in contact with a lower surface of the fixed vessel plate, and provided to be rotatable about an axial center in a vertical direction; and a hopper unit disposed immediately above the movable vessel plate, wherein the fixed vessel plate includes a first fixed vessel hole, located on one side in a circumferential direction about the axial center with respect to the hopper unit, and a second fixed vessel hole located on another side in the circumferential direction, the movable vessel plate includes a first movable vessel hole and a second movable vessel hole, which are located in a stated order toward the one side in the circumferential direction and are able to be disposed coaxially with the first fixed vessel hole, and a third movable vessel hole and a fourth movable vessel hole which are located in a stated order toward the another side in the circumferential direction and are able to be disposed coaxially with the second fixed vessel hole, in the fixed vessel plate, the first fixed vessel hole and the second fixed vessel hole are recessed holes that open downward, and have bottom surfaces provided to be movable up and down, and in the movable vessel plate, the first movable vessel hole, the second movable vessel hole, the third movable vessel hole, and the fourth movable vessel hole are recessed hole portions that open upward, a bottom surface of the first movable vessel hole and a bottom surface of the third movable vessel hole are provided to be movable up and down, and a bottom surface of the second movable vessel hole and a bottom surface of the fourth movable vessel hole are provided to be openable.

6 . The particulate matter filling device according to claim 5 , wherein
in the movable vessel plate, the first movable vessel hole includes:
a first movable vessel-side through hole penetrating in an up-down direction; and
an end surface of a first movable vessel-side moving pin that penetrates the first movable vessel-side through hole from below and is slidable in the up-down direction, and
the third movable vessel hole includes:
a third movable vessel-side through hole penetrating in the up-down direction; and
an end surface of a third movable vessel-side moving pin that penetrates the third movable vessel-side through hole from below and is slidable in the up-down direction.

7 . The particulate matter filling device according to claim 6 , wherein
the movable vessel plate includes:
a movement actuator for moving each of the first movable vessel-side moving pin and the third movable vessel-side moving pin in the up-down direction; and
a buffer actuator interposed between the movement actuator and each of the first movable vessel-side moving pin and the third movable vessel-side moving pin,
the movement actuator and the buffer actuator being provided in each of the first movable vessel hole and the third movable vessel hole.

8 . The particulate matter filling device according to claim 7 , wherein the particulate matter is a desiccant and/or an oxygen absorber.

9 . The particulate matter filling device according to claim 6 , wherein the particulate matter is a desiccant and/or an oxygen absorber.

10 . The particulate matter filling device according to claim 5 , wherein the particulate matter is a desiccant and/or an oxygen absorber.
