Definitions

  • the invention relates to a device with which containers such as hard gelatin capsules, blisters, vials or similar containers can be filled with powdery filling material.
  • contents may be food, luxury foods such as coffee powder, cocoa powder and the like; but the contents can also contain a drug and especially then very small, often non-flowable pulverized particles or consist only of such small particles. In particular, in the latter case, their handling is difficult, so that the filling of containers with such powders is technologically difficult.
  • the device has a powder in stock holding chamber and from this chamber with powder to be charged, rotatably driven metering roller.
  • the metering roller has Dosieraussparonne in their outer tube jacket.
  • Dosieraussparung which is a metering chamber
  • powder is sucked from the storage chamber into this metering chamber.
  • sucking in the powder is compressed above the metering chamber by means of a plunger dipping into the powder. The compression is to create a reproducibly equal volume distribution of the powder above the metering chamber.
  • the same powder ratios required in the storage chamber are additionally attempted to be achieved by two equalizers which can be moved back and forth in the storage container.
  • a slider movable back and forth on the surface of the powder present in the storage chamber helps to keep the height of the powder in the powder chamber constant.
  • a second pusher immersed in the powder is reciprocated in the powder so as to nullify a compaction of the powder within the powder bed which is unevenly high before the plunger is dipped, and thus to equalize the powder as a whole and thus also in depth. While the powder is being sucked into a respective metering chamber, the two slides are at rest. The compression of the powdery contents occurring in this metering principle deteriorates the inhalability of the medicament consisting of such contents. Also, damage to the particle structure of the powdery product can not be excluded in every case.
  • the present invention seeks to allow a gentle and accurate dosage of powdery contents.
  • the device according to the invention enables a volumetric dosing even of very small amounts of powder.
  • the powder can also consist of very small powder particles or contain such. This is achieved by virtue of the fact that the stirring tool present in the material store is designed so flexibly or consists of flexible material that it can spread the contents into the respectively available metering chamber. In the case of powdery contents which have been agglomerated, the easy deformability of such agglomerates is utilized in this coating process. The flexibility of the stirring tool limits the deformation forces acting on the powdery filling material.
  • the agitating tool or parts thereof may consist of silicone membranes with a thickness of about 0.5 mm (millimeters) to 3.0 mm.
  • the device according to the invention With the device according to the invention it is achieved that the powdery filling material is charged only by low energy input.
  • the known in the prior art disadvantages, such as damage of Greinpisme, excessive dust, heating and segregation of the contents are avoided.
  • the device of the invention requires no complex additional electronic equipment, as required for example when using ultrasonic generators.
  • the special stirring tool used in the device according to the invention can easily be integrated into existing metering systems - even subsequently.
  • the light compression of the powdery filling material during the coating process can be influenced by correspondingly different flexibility properties of the stirring tool.
  • This slight compression effect offers advantages if, for example, pulverulent filling material with very low density is to be filled into a comparatively small-volume metering chamber. Such very small metering chambers are required, for example, when filling blister cups.
  • a different compression of the powdery filling material nevertheless a quantitatively variable dosage can be achieved.
  • the stirring tool may have at least one flexible slide which can be driven in a rotary manner or linearly movable through the filling material. It is also possible to move slider and metering chamber relative to each other.
  • the stirring tool may have an axis of rotation which is arranged parallel to the axis of a plurality of metering chambers having metering roller.
  • At least one wing may be present as a kind of slider at this axis of rotation of the stirring tool. Missing areas may be present in the wing, but these are not present in that edge region of the wing that can be brought before the mouth of a metering chamber. In fact, areas of the wing must be movable in front of the mouth of a metering chamber so that the wing can push contents into the metering chamber. With a missing area in the edge of the wing, this insertion would not be possible.
  • At least one, preferably a plurality of swash plates can be attached to the axis of rotation of the stirring tool.
  • the axis of rotation of the stirring tool can also be designed as a screw.
  • the axis of rotation of the stirring tool can be driven at different speeds and / or in changing directions of rotation.
  • the stirring tool can also be suspended on a parallel to the axis of the metering roller holder according to another embodiment of the invention.
  • a stirring tool with at least two slides, which can be moved to and fro with mutually different distances over the metering chambers to be filled either in one direction or in opposite directions.
  • One of the two slides can be used to loosen up the Grecorebettes within the material storage, while the other slide is used for pouring of filling material in each of the existing metering chambers.
  • a filling device 10 is partially shown in cross section.
  • This filling device 10 has a metering roller 12, which is rotatably driven about a rotation axis 14 in the direction of rotation 16.
  • a plurality of metering chambers are arranged circumferentially parallel to its axis of rotation 14, of which a metering chamber 18 can be seen.
  • a material reservoir 20 is positioned with powdery filling material 22.
  • the powdery filling material 22 is filled out of the material reservoir 20 into the metering chamber 18.
  • a stirring tool 30 rotatable in the direction of rotation 26 is provided in the material reservoir 20 about its axis of rotation 24, which is arranged parallel to the rotational axis 14 of the dosing roller 12.
  • the direction of rotation 26 of the stirring tool 30, as well as the direction of rotation 16 of the metering roller 12, are oriented counterclockwise.
  • the agitating tool 30, which is shown in perspective in Fig. 5, has two wings 32, 34 which project from the axis of rotation 24 in opposite directions.
  • the wings 32, 34 are made of flexible material, which in the present example is in each case a silicone membrane.
  • the stirring tool 30 is positioned above the metering roller 12 or its metering chamber 18 in such a manner that in each case one blade, as in FIG. 1 of the blades 34, rests on the surface of the metering chamber 18 and powdery during the rotational movement of both the metering roller 12 and the stirring tool 30 Filling material 22 out of the material reservoir 20 and into the metering chamber 18 into it.
  • the two wings 32, 34 are used alternately and are thus used alternately to sweep powdery contents 22 into the metering chambers 18 into it.
  • the plurality of metering chambers 18 shown in FIG. 5 are filled by a respective one of the blades 32, 34 together with powdery filling material 22.
  • a filling device 10.2 a is shown, in which a flexible wing 38 is attached to a rod-shaped holder 36 which is arranged parallel to the rotational axis 14 of the metering roller 12 within the material reservoir 20.
  • This wing 38 is similar to how it is shown in Fig. 1 with the wing 34, with its end on the metering roller 12.
  • this filling device 10.2a only the metering roller 12 rotates in the direction of rotation 16. The blade 38 is at rest and is not rotationally driven. Also in this relative movement between the vane 38 and the metering roller 12, powdery contents 22 from the material reservoir 20 are scanned into the metering chambers 18 present in the metering roller 12.
  • the filling device 10.2b shown in FIG. 2b differs from the device 10.2a in that a vane 38.2 is not fastened directly to the rod-shaped holder 36 but indirectly via a self-supporting collar wall 40 fixed to the rod-shaped holder 36.
  • this Kragwand 40 changes the flexibility property of the respective wing 38.2, and that with unchanged material properties of the wing 38.2.
  • the agitator 30.3 shown in Fig. 3 has at its axis of rotation 24 with mutually spaced swash plates 44. These swash plates 44 are pulled through and shown in phantom in a rotated by 180 degrees to position. It can be seen that also through these swash plates 44 contents can be displaced parallel to the axis of rotation 24 and thus can be scanned into the dosing chambers 18.
  • Such a horizontal displacement is also possible according to FIG. 4 with a stirring tool 30.4, which is designed as a screw 46 or in the form of two screws 46 arranged parallel to one another with their axes of rotation 24.
  • a stirring tool 30.4 which is designed as a screw 46 or in the form of two screws 46 arranged parallel to one another with their axes of rotation 24.
  • twin-screw agitator 30.4 two rows of juxtaposed metering chambers 18 can be filled simultaneously.
  • the two screws 46 are driven in different directions of rotation 26, 26.4.
  • the agitating tool 30.6 of FIG. 6 has holes 48 in its two wings 32, 34.
  • the holes 48 cause that by this stirring tool 30.6 in relation to the agitator 30 less contents in the material storage 20 is herumgeschaufelt.
  • edge-fault areas 50 are present in the two wings 32, 34.
  • the edge defect areas 50 are arranged such that the central alignment line 52 present between adjacent edge defect areas 50 is aligned with the center 54 of the respective mouth 56 of a metering chamber 18. With their edge deficiency regions 50, the stirring tool 30.7 does not come into the area of the metering chambers 18.
  • the application of powdery filling material by means of the agitating tool 30.7 thus takes place with those regions of the two wings 32, 34 which are present in each case between the edge deficiency regions 50.
  • similar to the stirring tool 30.6, in comparison to the stirring tool 30 comparatively less powdery filling material 22 is scooped around in the material store.
  • a stirring tool 60 can be moved in a direction parallel to the longitudinal direction of the metering roller 12, in a first direction of movement 62 (FIG. 8) and in the opposite direction, in the second direction of movement 64 and move here.
  • the stirring tool 60 has a first and second slide 66, 68.
  • the leading in the direction 62 first slider 66 is positioned at a distance 70 above the metering roller 12 and thus above their metering chambers 18. Because of this distance 70, the first slide 66 can not be used for filling the metering chambers 18 but only for loosening up and dissolving agglomerates in the powdery filling material 22.
  • the application takes place with the first slide 66 in the direction of movement 62 subsequent second slide 68.
  • the slide 66, 68 are formed flexible or made of flexible material, because alternately both slides must be used once each for pouring of filling material 22 into the metering chambers 18.
