To provide a method and device for packing a bulky material which can increase the compaction-packing rate of the bulky material to a bag, stabilize the form of the packed material, and make the bulky material advantageous when stored or transported as freight.
To pack bulky material, a bag 8 which is airtight and flexible is so held as to have its opening in an upwardly open state. A prescribed quantity of bulky material 7 having a volume larger than the inside capacity of the bag before compaction is put inside the bag and into a passageway for compaction packing continued to the opening of the bag. Through this compaction packing passageway a vacuum tube 4a together with a press head 3a are lowered into the bag 8. The bag 8, while its bottom is held on the floor, etc., and the compaction packing passageway are packed with the bulky material 7 with compaction by the press head 3a. After the compaction packing, with the vacuum tube 4a left in the bag 8, the press head 3a is lifted, drawn out of the bag 8, and replaced. The opening of the bag 8 is closed, except the part having the vacuum tube 4a, and the air inside the bag is discharged through the vacuum tube. After the discharge, the vacuum tube 4a is lifted, drawn out of the bag 8, and replaced and the bag is immediately sealed at the opening.
