Abstract
Description
- 1. Field of the Invention
- The invention relates to a metering device for metering and dispensing powder into hard gelatin capsules.
- 2. Description of the Prior Art
- A metering and dispensing device of the type with which this invention is covered is disclosed by DE 196 51 237 A1. The known device is designed for metering and dispensing powder into hard gelatin capsules and to that end, has a powder deflecting body as well as a tamping and ejecting die so that powder can be compressed in metering bores of a metering disk and can be transferred into prepared bottoms of hard gelatin capsules. The known device should be improved in such a way that it is suitable for metering granular products or products in small pieces, in particular pharmaceutical products such as microtablets, capsules, dragées, or the like, wherein the highest possible performance and the gentlest treatment of the product should be achieved.
- The metering device according to the invention has the advantage over the prior art that it is mechanically simple in design and permits a high performance with metering that is gentle to the product.
- The invention will be better understood and further objects and advantages thereof will become more apparent from the ensuing detailed description taken in conjunction with the drawings, in which
- FIG. 1 is a simplified longitudinal section through the metering device according to the invention,
- FIG. 2 is a top view of a metering disk,
- FIG. 3 shows a detail from FIG. 2,
- FIG. 4 shows an arrangement of metering bores that has been modified in relation to FIG. 3, and
- FIG. 5 shows a perspective view of a tablet filling shaft.
- The
device 10 shown in FIG. 1 is used to meter and dispense so-calledmicrotablets 1 into capsule bottoms 2 of hard gelatin capsules. However, thedevice 10 can also be used to meter other products, such as capsules, dragées, bonbons, or the like. Instead of capsule bottoms 2, other suitable receptacles for the products can be used, e.g. cups of a blister packing strip. - The
device 10 has afilling material container 11, which is comprised of ametering disk 12 and a fillingmaterial container ring 13 connected to themetering disk 12. The fillingmaterial container 11 is supported so that it can rotate around anaxis 14 which is pivoted in relation to thevertical axis 15 by an angle α which in the exemplary embodiment is approx. 30 degrees. - As can best be inferred from FIGS. 2 and 3, a large number of cross sectionally
round metering bores 17 are embodied in themetering disk 12. In the exemplary embodiment, themetering bores 17 are arranged in such a way that at a particular radius R from theaxis 14, there is a group of five or fourmetering bores 17 every 45 degrees of rotation angle. Furthermore, according to FIG. 3, a group of fivemetering bores 17 with a radius r1 from theaxis 14 and four neighboringmetering bores 17 with a radius r2 from theaxis 14 are combined into arespective bore group 18, which is associated with one capsule bottom 2. If, according to FIGS. 2 and 3, the groups of four and fivemetering bores 17 are disposed offset from each other at larger radii, then a particularly dense grouping ofmetering bores 17 for abore group 18 can be achieved in a smaller radius range. - According to FIG. 1, two
microtablets 1 are disposed one over the other in eachmetering bore 17, wherein the diameter of themetering bores 17 is respectively slightly greater than the diameter of themicrotablets 1. In connection with FIGS. 2 and 3, it is clear that in accordance with the ninemetering bores 17 associated with abore group 18, a total of eighteenmicrotablets 1 are dispensed into a capsule bottom 2. - A plate- or ring-
shaped countersupport 19 is disposed against the underside of themetering disk 12 and closes the bottoms of themetering bores 17, with the exception of atransfer region 20, as thefilling material container 11 is rotated around theaxis 14. In thetransfer region 20, thecountersupport 19 has arecess 21 for acapsule filling shaft 22. - The block-shaped
tablet filling shaft 22 has a funnel-like shaft 24 for eachbore group 18. On the side oriented toward themetering disk 12, thisshaft 24 has an oblong entry cross section 25 (see FIG. 5) which is adapted in accordance with the respective outer limit of abore group 18 and on the side oriented toward the capsule bottoms 2, has anexit cross section 26 which is adapted to the diameter of the capsule bottom 2. - A
capsule part carrier 27 with bores 28 for the capsule bottoms 2 is disposed underneath thetablet filling shaft 22. In order to receive themicrotablets 1, thecapsule part carrier 27 can be pivoted according to FIG. 1 into a position in which the capsule bottoms 2 are flush withexit cross sections 26 of theshafts 24. In order to close the capsule bottoms 2, thecapsule part carrier 27 can be pivoted away laterally. For the design and function of acapsule part carrier 27 of this kind in connection with a capsule filling and closing machine, reference is made to DE 38 30 013 A1, which is incorporated herein by reference to the extent that thedevice 10 can be a component of a capsule filling and closing machine of this kind. - A guide and
drive ring 30 is fastened to the underside of themetering disk 12 in its edge region. On its inner circumference, the guide anddrive ring 30 has aninternal gearing 31, which is disposed in operational connection with adrive pinion 32 of the rotating drive of thefilling material container 11, which is preferably embodied as a servomotor. Acontinuous guide groove 33 is embodied on the outer circumference of the guide and drivering 30 and is engaged by threeguide rollers 34 which are disposed offset from one another by 120 degrees and provide for the support of thefilling material container 11, wherein only oneguide roller 34 can be seen in FIG. 1 because of the view selected. - It is also essential that according to FIG. 1, the filling material, which is disposed in the filling
material container 11 and is in the form ofmicrotablets 1, does not completely fill thefilling material container 11, but only reaches afilling material level 35. This fillingmaterial level 35 is below the level of theentry cross sections 25 of thecapsule filling shaft 22 and thetransfer region 20. Furthermore, the angle a of theaxis 14 of thefilling material container 11 must be big enough that upon rotation of themetering disk 12,microtablets 1 disposed above themetering bores 17 roll back into thestorage region 36 of the filling material due to the downward pulling force of the slope. - The
device 10 operates as follows: Thefilling material container 11 is rotated either cyclically or continuously by thedrive pinion 32. In the course of rotation, the metering bores 17 travel down into thestorage region 36 withmicrotablets 1, as a result of which twomicrotablets 1 are disposed one over the other in eachmetering bore 17. With further rotation of themetering disk 12, themetering bores 17 filled with themicrotablets 1 travel out of thestorage region 36. Ifadditional microtablets 1 have collected in the region of themetering bores 17, then with further rotation of themetering disk 12, theseadditional microtablets 1 roll or slide back into thestorage region 36 of thefilling material container 11 due to the downward pulling force of the slope acting on them. As soon as themetering bores 17 come into line with theshafts 24 of thetablet filling shaft 22, themicrotablets 1 fall out of the metering bores 17 into thetablet filling shaft 22 and from there into the readied capsule bottoms 2. The filled capsule bottoms 2 are then pivoted away by means of thecapsule part carrier 27, out of the filling position shown in FIG. 1, whereupon other, empty capsule bottoms 2 are brought under thecapsule filling shaft 22. Then the events described above are repeated. - It should also be mentioned that the form of the metering bores is not limited to
round metering bores 17. Rather, themetering bores 17 a can also be embodied e.g. as oblong in accordance with FIG. 4 so that each pair ofmicrotablets 1 can be disposed next to one another in a plane. In this instance, the thickness of the metering disk is such that it is only possible to arrange themicrotablets 1 in a plane of the metering disk or in themetering bores 17 a is possible. Furthermore, the arrangement of the metering bores 17 a shown in FIG. 4 is such that they are respectively offset from one another by 90 degrees so that a space-saving arrangement is achieved. - The foregoing relates to preferred exemplary embodiments of the invention, it being understood that other variants and embodiments thereof are possible within the spirit and scope of the invention, the latter being defined by the appended claims.
