Title:
METHOD FOR AUTOMATICALLY PACKING COARSE GRANULE AND DEVICE THEREFOR
Document Type and Number:
Japanese Patent JP3406999
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To enable surface sticky coarse granules to be continuously conveyed smoothly and accurately supplied to specified molding dies to be fully packed in the dies by temporarily holding a specified volume of the conveyed surface sticky coarse granules of a hard material and supplying the coarse granules retained in the molding dies all at once to pack the coarse granules in the molding dies.
SOLUTION: Raw material supply apertures 37 are arranged in close proximity to spots located almost perpendicularly from the lower end parts 23 of molding dies 35, and switching valves 24 are almost instantaneously switched. As soon as the switching valves 24 are opened, coarse granules M fall to be released. After that, the switching valves 24 are closed to resume the holding of the coarse granules M. At the same time, rollers 31 are driven to rotate to move a pallet 32 so that the positions of the lower end parts 23 and the aperture parts 37 are adjusted to replace the molding die 35 filled with the coarse granules M with the unfilled molding die 35, and then are stopped. In this case, the operating efficiency is enhanced by synchronizing the operation to move and stop the pallet 32 with the operation to drop/release the coarse granules M and stop the drop/release procedures through switching the switching valve 24. Further, the continuous operation can be performed for a long time without interruption.
