Definitions

  • the invention relates to a device and a method by means of which a powdery filling material can be metered.
  • the pulverulent filling material can then be transferred, in particular, into hard gelatine capsules but also into other containers.
  • Such devices and methods are used in particular in the pharmaceutical industry for filling hard gelatin capsules with drugs.
  • the powder to be filled is filled into a metering chamber, for example into the bores of a metering disk.
  • the powder is then compacted by means of a punch in the metering chamber.
  • the stamp performs at least one stroke, so that a compact arises.
  • the finished compact is then expelled from the metering chamber by opening the metering chamber and ejecting the compact by means of a punch.
  • the present invention seeks to provide an improved device for Specify metering of powdery product, can be avoided by means of metering inaccuracies.
  • the device according to the invention for dosing powdery filling material has a product container in which the powdery filling material can be kept in stock. From this product container, a defined amount of the powdery filling material can be removed by means of a metering tool and into a container - for example, in the capsule lower part of a hard gelatin capsule - transferred.
  • the metering tool is designed to be movable in its longitudinal direction.
  • the metering tool can be offset by a drive unit in a rotational movement about its longitudinal axis. By means of this drive unit, a defined rotational movement can be carried out, which prevents adhesion of the pulverulent solid to the metering tool. As a result, dose inaccuracy can be avoided, which leads to a lower reject rate and thus to increased productivity.
  • the drive unit can allow both a clockwise rotational movement and a counterclockwise rotational movement.
  • a reciprocal rotation in a clockwise and counterclockwise direction in a particularly advantageous embodiment, a pendulum or shearing motion can be generated, by means of which adherence of solids to the metering tool can be prevented particularly effectively.
  • a first motor drive can be present, by means of which the metering tool can be moved along its longitudinal axis.
  • the rotation of the Dosing tool can be done by means of a separately formed drive unit. The rotational movement could be carried out in this way, regardless of the transport movement of the metering tool by means of the first motor drive.
  • several metering tools could be moved by means of a common motor drive in the longitudinal direction.
  • the metering tool can be designed as a stamp.
  • at least one metering chamber can be formed at the bottom of the product container into which a defined quantity of the product can be filled.
  • the contents in the metering chamber can first be compacted by the stamp into a compact. Subsequently, the ejection of the compact from the metering chamber can be effected by the punch.
  • the rotational movements of the stamp can be carried out during the compaction of the powdery contents in the metering chamber and / or during the ejection of the compact from the metering chamber.
  • Rotational movements during the compacting of the powdery filling material in the metering chamber can already prevent the adhesion of the compact to the stamp.
  • rotational movement during ejection of the compact from the metering chamber may provide easier release of the compact from the punch.
  • a rotational movement, or a combination It would also be possible to let the stamp perform a rotational movement throughout.
  • the metering tool can be designed as a jack.
  • the pipette can be immersed in the powder bed present in the product container to remove a defined amount of contents. Subsequently, the In the metering chamber of the riser existing amount of powder are transferred to a waiting container.
  • the rotational movements of the piercer may be performed during the immersion of the piercer into the powder bed and / or during the ejection of the powder from the metering chamber of the piercer.
  • Rotational movements during the immersion of the piercer in the powder bed can already prevent the early adhesion of powder to the inner walls of the metering chamber of the piercer and thus allow complete and accurate filling of the metering chamber.
  • rotational movement during ejection of the powder from the metering chamber of the piercer can provide complete and easy ejection of the powder.
  • a rotational movement, or a combination It would also be possible to have the piercer continuously perform a rotational movement.
  • At least one rotational movement of the metering piston should occur during a rotational movement of the piercer.
  • This rotational movement may already be sufficient to effectively prevent the adhesion of powder in the metering chamber.
  • the rotational movements of metering piston and metering sleeve can run in opposite directions, so that a shearing movement takes place.
  • FIG Fig. 1 and 2 A first embodiment of the device 10 according to the invention is shown in FIG Fig. 1 and 2 shown.
  • the device 10 has as a dosing a punch 20, which can be offset by means of a motor drive not shown here in a vertical lifting movement (arrow 22).
  • the punch 20 moves through the lifting movement 22 in the bore 24 of a metering disk 26.
  • Each bore 24 of the metering disk 26 forms a metering chamber.
  • Fig. 1 the bore 24 is closed by a plate 28 from the bottom.
  • the bore 24 can first be filled with a defined amount of filling material.
  • the punch 20, the powder present in the bore 24 then according to Fig. 1 compact to a compact 30.
  • a drive unit 32 in a rotational movement (arrow 34).
  • the rotation 34 of the punch 20 during the compacting of the filling material can ensure that the resulting compact 30 does not adhere to the underside of the punch 20.
  • the rotational movement 34 takes place at a constant speed in the clockwise direction.
  • the rotation 34 could also be counterclockwise.
  • the speed during the rotational movement 34 could be varied.
  • the rotational movement could consist of several smaller, jerky movements.
  • the direction of rotation could be changed at predetermined intervals, so that first clockwise and then rotated counterclockwise. This change of direction could then be repeated as often as desired.
  • the capsule base 40 of a hard gelatin capsule is positioned below the dosing chamber 24 by means of a receiving unit 42.
  • the capsule lower part 40 can be laterally removed by the receiving unit 42, so that a new capsule lower part can be positioned below the dosing chamber 24.
  • the filled capsule lower part 40 can then be provided in other processing stations with another compact or another product or even directly closed.
  • the feeding and removing the Capsule bases can be done in particular by a rotary indexing table, as he, for example, from the EP 1 415 637 A1 or the EP 2 135 810 A1 is known.
  • the punch 20 during the ejection of the compact 30 by the drive unit 32 in a rotational movement (arrow 44) is added.
  • the rotation 44 of the punch 20 during the ejection of the compact 30 the compact 30 is more easily released from the underside of the punch 20 and can fall safely and reliably into the capsule base 40.
  • the rotational movement 44 can be made comparable to the rotational movement 34 with a constant rotational speed and direction but also with varying rotational speed and / or rotational direction. It would be possible, both the rotational movement 34 during compacting ( Fig. 1 ) as well as the rotational movement 44 during ejection ( Fig. 2 ). In this case, the two rotational movements 34, 44 may be identical, but also adapted to the different situations adapted differently. Depending on the contents used, the speed of the rotary indexing table and / or the size of the compact 30, however, it may be sufficient to provide only the rotational movement 34 during the compacting of the product or the rotational movement 44 during the ejection of the compact 30 from the metering chamber 24.
  • FIG 3 and 4 A second embodiment of the device 12 according to the invention is shown in FIG 3 and 4 shown.
  • the device 12 has as a dosing a piercer 50, which can be offset by means of a motor drive, not shown here in a vertical stroke movement (arrow 52).

  • the piercer 50 has an outer metering sleeve 60 and a metering piston 62 guided displaceably therein.
  • the metering piston 62 is retracted somewhat in relation to the free edge 64 of the metering sleeve 60, so that a metering chamber 66 is formed inside the metering sleeve 60.
  • the dosing sleeve 60 is in Fig. 3 with its free edge 64 in the present in the product container 54, a powder bed forming filling 56 dipped.
  • the metering chamber 66 is filled with the filling material 56.
  • the metering piston 62 of the piercer 50 is set in a rotational movement (arrow 72) by a drive unit 70 in the embodiment shown here.
  • This rotation 72 of the metering piston can ensure that the filling material 56 is uniformly distributed in the metering chamber 66, so that an optimal and reproducible filling of the metering chamber 66 is achieved.
  • the rotational movement 72 takes place at a constant speed in the clockwise direction.
  • the rotational motion 72 could also be counterclockwise.
  • the speed during the rotational movement 72 could be varied.
  • the rotational movement could consist of several smaller, jerky movements.
