BRIEF SUMMARY
PRIOR ART
The invention relates to an apparatus for metering and dispensing powder into hard gelatin capsules or the like. Known apparatuses of this kind have a cup-shaped product container, in the bottom of which a plurality of groups of bores are formed that each cooperate with stuffing dies that are movable up and down and are combined into stuffing die stations. Below the product container and in coincidence with the stuffing dies, a brace in the form of a ring is provided, so that in the nonmoving phases of the intermittently rotated product container, the stuffing dies dipping into the bores form powder compacts. During a further nonmoving phase of the product container, the thus-formed powder compacts are shoved by transfer dies into capsule underparts furnished below the bores. To prevent loose powder from collecting above the powder compacts and reaching the capsule underparts as the powder compacts are inserted, the transfer dies are surrounded by a powder repeller. To enable achieving the highest possible output for a given size of the product container, the bores for the stuffing and transfer dies are all disposed near the container wall of the product container. This makes the largest possible number of bores or stuffing dies reachable at each stuffing die station.
Because of the powder repeller surrounding the transfer dies and repelling the powder, the problem arises, because of the disposition of the bores near the container wall, that the bores immediately following the powder repeller in the first stuffing die station are not supplied adequately or uniformly with powder. This leads to inaccuracies of metering, which mean that the number of bores at the stuffing die station following the powder repeller, and thus necessarily at all the stuffing die stations, has to be reduced if the desired metering accuracy is to be attained.
ADVANTAGES OF THE INVENTION
The apparatus according to the invention for metering and dispensing powder into hard gelatin capsules or the like, has the advantage over the prior art that for a given product container size, high output and simultaneously high metering accuracy can be attained.
Further advantages and advantageous refinements of the apparatus according to the invention for metering and dispensing powder into hard gelatin capsules or the like will become apparent from the set forth hereinafter description.
By means of a baffle element in the product container, powder can be delivered in targeted fashion to individual bores, thus additionally increasing the output.
To create additional space for devices that cooperate with the metering container, it is advantageous for part of the bottom of the product container to be elevated in its outer region.
BRIEF DESCRIPTION OF THE DRAWING
One exemplary embodiment of the invention is shown in the drawing and will be described in further detail below.
FIG. 1 shows an apparatus for metering and dispensing powder into hard gelatin capsules or the like in a longitudinal section; and
FIG. 2 shows a product container in a section taken in the plane II--II of FIG. 1.
DESCRIPTION OF THE EXEMPLARY EMBODIMENT
The apparatus 10 shown in FIG. 1 for metering and dispensing powder 1 into hard gelatin capsules or the like has a cup-shaped, incrementally rotatable product container 11 for the powder 1. The product container 11 has a disklike bottom 12, which four groups 2-5, each of five bores 13, are formed. The center points of the bores 13 of each group 2-5 are each disposed on one straight-line segment, and the groups 2-5 are each offset by 90.degree. from one another in an outer region of the bottom 12. The bottom 12 is surrounded by a jacket 15, which inside the product container 11 forms a region that is annularly raised relative to the bottom 12. This is attained by providing that the jacket 15 has two vertically disposed wall portions 17, 18, which are joined together by a horizontally disposed bottom portion 19. Consequently the product container 11 has a lesser diameter in the region of the first wall portion 17
