Definitions

  • An apparatus for filling gelatin capsules or the like is provided with a unified (single) closed unit.
  • a powder dosing disc and a filling material container are combined within the unified closed unit.
  • the filling material container is adapted to hold powder to be placed in the capsules.
  • the powder dosing disc is cyclically rotatable and has a plurality of bores therein.
  • a plurality of tamping dies are operatively arranged to press powder into the bores in the dosing disc.
  • Means are provided for holding bottoms of the capsules to be filled beneath the bores in the dosing disc.
  • a plurality of transfer dies are provided for pushing pressed molds of the powder within the bores into the capsule bottoms.
  • This invention relates to an apparatus'for filling hard gelatin capsules or the like with powder with the aid of tamping dies.
  • the invention relates, more particularly, to an apparatus for filling hard gelatin capsules or the like with powder, wherein the powder, located in a filling material container, is pressed with the aid of tamping dies into bores of a cyclically rotating dosing disc, and wherein subsequently the molds of powder, pressed in this manner within the bores, are pushed with the aid of transfer dies into capsule bottoms held in readiness beneath the bores in the dosing disc.
  • an apparatus for filling gelatin capsules or the like with powder which includes a filling material container for holding powder to be placed in the capsules.
  • a cycli- 2 cally rotatable powder dosing disc having a plurality of bores therein is provided.
  • a plurality of tamping dies are arranged to press powder into the bores of the dosing disc.
  • Means are provided for holding bottoms of the capsules beneath the bores of the dosing disc.
  • a plurality of transfer dies are arranged to aid in pushing pressed molds of the powder in the bores into capsule bottoms when in place in the means for holding.
  • a unified (single) closed unit is provided, the dosing disc and the filling material container being combined within this closed unit.
  • the known apparatus disclosed in the German Pat. No. 1,174,244 had been changed in such a manner that instead of tamping the powder in the capsule bottoms, the tamping of the powder occurs in the bores of the dosing disc.
  • the bores are made in a size corresponding to the amount of powder to be filled and the capsule bottoms are held in readiness underneath the disc for insertion of the powder in pressed mold form.
  • the apparatus is so designed that the dosing disc is constituted by the bottom of the filling material container, which includes a shroud enclosing the dosing disc and a cover having apertures for the tamping dies and the transfer dies.
  • a distributor member is provided to strip the powder in that region from the dosing disc. This distributor member also serves for guidance of the transfer dies.
  • the tamping dies can be adjusted in height and are desirably elastically mounted.
  • a centrally disposed delivery tube connected with the cover of the filling material container, and also a conveyor screw (helix) for delivering the powder supplied in dependence on the level of the powder on the dosing disc.
  • An apparatus of this type guarantees the careful placement of equal quantities of powder in the dosing chambers and for the transfer into the gelatin capsules, while avoiding loss of any significant portion of the powder. Soiling of the surrounding parts is also avoided, and the demixing of the powder is substantially prevented.
  • FIG. 1 is a side view, partially in section, of an apparatus for filling gelatin capsules or the like with powder according to a preferred, illustrative example of the present invention.
  • FIG. 2 is a top view of the apparatus shown in FIG. 1, also partially in section.
  • the illustrative embodiment of an apparatus for filling gelatin capsules with powder includes a dosing disc 1 which has a plurality of bores 2 therein; these bores 2, for example, as can be seen especially in FIG. 2, are grouped together in groups of six.
  • the dosing disc 1 contains a total of six such groups, three being visible in FIG. 2. Each group,
  • a shroud 3 and a cover 4 are provided to define structurally with the disc 1 a filling material container.
  • the cover 4 has a number of apertures 5 which receive a number of tamping dies 6 and a corresponding number of transfer dies 7.
  • the tamping dies 6 are elastically mounted and are adjustable by manual manipulation of associated setting members 10.
  • a distribution member 11 is installed in the vicinity of the transfer dies 7. The distribution member 11 is operatively arranged to strip or to scrape the powder in the vicinity of the transfer dies 7 from the dosing disc 1 and simultaneously serves as a guide for guiding the transfer dies7.
  • a limiting plate 12 which closes the bores 2 in the downward direction.
  • the capsule bottoms which receive the pressed molds.
  • These capsule bottoms 13 are suitably located in bores of a disc 14 which also cyclically rotates.
  • the powder to be packaged is introduced, with the aid of the conveyor helix or screw 9 through the delivery tube 8 into the filling material container defined by the dosing disc 1, the shroud 3 and the cover 4.
  • the delivery of the filling material occurs in dependence on the level of filling material already present on the dosing disc 1. For this purpose, known techniques and means (not shown for the purpose of clarity) are used.
  • the powder which has fallen into the bores 2 is compressed against the plate 12 by the tamping dies 6. This process displaces the air contained in the filling material so that homogeneous pressed molds of the powder are formed. In accordance with the number of tamping stations, the powder is compressed five times in each of the bores 2.
  • the weight and the hardness of each pressed mold is influenced, firstly, by the level of the powder in the filling material container 1, 3, 4 and, secondly, by the maximum depth of insertion of the tamping dies 61into the bores 2 of the dosing disc 1, as well as by pressure compensation springs 15 associated, with the tamping dies 6.
  • the adjustment and periodic regulation of the tamping dies .6 occur centrally for each station by manipulation of the setting members 10.
  • the distribution member 11 which also serves for the guiding of the transfer dies 7 within the region of the transfer station, has the task of keeping this region free of powder. After the pressed molds have been pushed into the capsule bottoms 13 by the transfer dies 7, the capsule bottoms 13 are combined with capsule tops in a known manner (not shown).
  • An apparatus for filling gelatin capsules or the like with powder comprising, in combination:
  • said dosing disc is constituted by the bottom of said filling material container, said container including. a shroud member enveloping said dosing disc and a cover mem* ber containing apertures for receiving said tamping dies and said transfer dies.
  • An apparatus further including, within the vicinity of said transfer dies, a distribu-. tion member for expelling pressed molds and for strip ping powder in that vicinity from said dosing disc.
  • An apparatus including a centrally disposed delivery tube for the purpose of delivery of the powder, communicating with said cover member of said filling material container, and a conveyor means associated with said delivery tube for delivering powder in dependence on the level of the powder on said dosing disc.
