DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an apparatus for filling powder, which introduces a predetermined amount of powder into each of receiving holes formed at the peripheral edge portion of a rotary disk from a powder hopper, intermittently rotates the rotary disk, and discharges and fills the powder introduced into the receiving holes, into powder containers disposed below the receiving holes when the receiving holes reach a discharging and filling portion.
2. Description of the Related Art
Conventionally known as an apparatus for filling powder by utilizing a rotary disk, which is formed with a plurality of receiving holes at the peripheral edge portion of a rotary disk and adjusts the amount to be filled by the receiving holes and then fills a predetermined amount of powder into each of powder containers is the apparatus disclosed in, for example, U.S. Pat. No. 2,540,059 or Japanese Patent Publication No. Hei 4-22761.
These apparatuses are each provided with a rotary disk (51) at the peripheral edge portion of which a plurality of receiving holes (58) are equidistantly formed, an intermittent rotation drive shaft (52) interlockingly connected to the rotary disk (51), a slide valve (53) having a sucking port (54) and a discharging port (55), and a powder hopper (56) having an agitator (57) arranged therein, for example, as shown in FIGS. 8 to 10. The rotary disk (51) is disposed below the powder hopper (56) with its rotational axis (C) positioned horizontal. The rotary disk (51) is provided with a vacuum sucking portion (60) at its upper portion and with a discharging and filling portion (61) at its lower portion, respectively. The sucking port (54) and the discharging port (55) of the slide valve (53) are connected to the receiving hole (58) located at the vacuum sucking portion (60) and to the receiving hole (58) at the discharging and filling portion (61) in communication therewith, respectively.
The receiving holes (58) are cylindrically concaved in the peripheral side surface of the rotary disk (51). The center axes of the cylindrical receiving holes (58) are radially and equidistantly arranged from the center of the rotary disk (51). Arranged at the innermost portion of each of the receiving holes (58) is a rodlike amount-adjusting member (64) having a filter (63) at its leading end. Through this adjusting member (64) a receiving hole (58) is connected to the discharging port (54) or the sucking port (55) in communication therewith. The volume within a receiving hole (58) is adjusted by advancing or retreating the adjusting member (64) along the center axis of the receiving hole (58).
The agitator (57) arranged in the powder hopper (56) has its center axis (65) positioned horizontal, and its agitating blades (66) rotate in a vertical plane. An opening (59) of the receiving hole (58) positioned at the vacuum sucking portion (60) is arranged to face the interior of the powder hopper (56) from below and introduces a predetermined amount of powder (P) within the powder hopper (56) into the receiving hole (58) by the centrifugal force resulting from the agitation of the agitator (57) and the vacuum pressure from the sucking port (54).
The powder (P) introduced into the receiving hole (58) at the vacuum sucking portion (60) moves with the receiving hole (58) to the lower discharging and filling portion (61) by the intermittent rotation of the rotary disk (51).
Provided below the rotary disk (51) is a path (68) for transporting powder containers (67) such as vials. This path (68) is constituted to cooperate with a control wheel (69) for stopping a transport conveyor (70) and the powder containers (67) at a predetermined position so as to send the powder containers (67) to below the discharging and filling portion (61) in order. And when the rotary disk (51) is rotated and then a receiving hole (58) reaches the lower discharging and filling portion (61), the opening (59) is made to face the powder container (67) positioned therebelow and then the powder (P
