Definitions

  • the invention relates to a device and a method by means of which a powdery filling material can be dosed.
  • the powdery contents can then be transferred, in particular into hard gelatine capsules, but also into other containers.
  • Devices and methods of this type are used in particular in the pharmaceutical industry for filling hard gelatine capsules with drugs.
  • the powder to be filled is filled into a dosing chamber, for example into the bores of a dosing disk.
  • the powder is then compacted in the dosing chamber using a stamp.
  • the ram performs at least one lifting movement, so that a compact is formed.
  • the finished compact is then pressed out of the dosing chamber by opening the dosing chamber and ejecting the compact by means of a stamp.
  • a stamp For example, in DE 10 2015 206407 A1 shown.
  • the invention is based on the object of specifying an improved device for dosing powdered filling material, by means of which dosing inaccuracies can be avoided.
  • the device according to the invention for dosing powdery filling material has a filling material container in which the powdery filling material can be kept in stock.
  • a defined quantity of the powdery filling material can be removed from this filling material container by means of a metering tool and transferred to a container, for example to the lower part of a hard gelatine capsule.
  • the dosing tool is designed to be movable in its longitudinal direction.
  • the dosing tool can be set into a rotational movement about its longitudinal axis by a drive unit.
  • a defined rotational movement is carried out by this drive unit, which prevents the powdered solid from adhering to the dosing tool. Dosing inaccuracies can thus be avoided, which leads to fewer rejects and thus to increased productivity.
  • a first motor drive by means of which the metering tool can be moved along its longitudinal axis.
  • the dosing tool is rotated by means of a separately designed drive unit.
  • the rotational movement can affect this Way done independently of the transport movement of the metering tool by means of the first motor drive.
  • several dosing tools could be moved in the longitudinal direction by means of a common motor drive.
  • the drive unit can enable both a clockwise rotational movement and a counter-clockwise rotational movement.
  • an alternating clockwise and anti-clockwise rotation can generate a pendulum or shearing movement, which can particularly effectively prevent solids from adhering to the metering tool.
  • the dosing tool is designed as a stamp.
  • at least one dosing chamber is formed at the base of the filling material container, into which a defined quantity of the filling material can be filled.
  • the filling material in the dosing chamber can first be compacted by the stamp to form a compact. The compact can then be ejected from the dosing chamber by the plunger.
  • the rotary movements of the ram can be carried out during the compaction of the powdery filling material in the dosing chamber and/or during the ejection of the compact from the dosing chamber.
  • Rotational movements during the compaction of the powdered filling material in the dosing chamber can already prevent the compact from adhering to the stamp.
  • a rotational movement during the ejection of the compact from the dosing chamber can ensure that the compact can be detached more easily from the plunger.
  • a rotational movement can be applied during only one of the two processes, or a combination. It would also be possible to have the punch continuously perform a rotational movement.
  • the dosing tool can be designed as a siphon.
  • the pipette can be immersed in the powder bed present in the filling material container in order to remove a defined quantity of filling material. Then the amount of powder present in the dosing chamber of the pipette can be transferred to a container that is available.
  • the rotational movements of the siphon can be carried out during the immersion of the siphon into the powder bed and/or during the ejection of the powder from the dosing chamber of the siphon.
  • Rotational movements during the immersion of the pipette into the powder bed can already prevent powder from adhering to the inner walls of the dosing chamber of the pipette at an early stage and thus enable the dosing chamber to be filled completely and precisely.
  • a rotational movement during the ejection of the powder from the dosing chamber of the siphon can ensure a complete and easy ejection of the powder.
  • a rotary movement can only be applied during one of the two processes, or a combination. It would also be possible to have the siphon continuously perform a rotational movement.
  • At least one rotational movement of the dosing piston should take place during a rotational movement of the siphon.
  • This rotational movement can already be sufficient to effectively prevent powder from sticking in the dosing chamber.
  • the dosing sleeve could also perform a rotational movement.
  • the rotational movements of the dosing piston and dosing sleeve can run in opposite directions to one another, so that a shearing movement takes place.
  • the device 10 is in Figures 1 and 2 shown.
  • the device 10 has a stamp 20 as a dosing tool, which can be set in a vertical lifting movement (arrow 22) by means of a motor drive, not shown here.
  • the plunger 20 moves through the stroke movement 22 in the bore 24 of a metering disk 26.
  • Each bore 24 of the metering disk 26 forms a metering chamber.
  • the bore 24 is closed by a plate 28 from the underside.
  • the bore 24 can initially be filled with a defined quantity of filling material.
  • the punch 20 can then in accordance with the powder present in the bore 24 1 compact to a pellet 30.
  • the plunger 20 in the embodiment shown here is set into a rotational movement (arrow 34) by a drive unit 32 .
  • the rotation 34 of the plunger 20 during the compacting of the filling material can ensure that the compact 30 being produced does not stick to the underside of the plunger 20 .
  • the rotational movement 34 takes place at a constant speed in the clockwise direction.
  • the rotational movement 34 could also take place in a counter-clockwise direction.
  • 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 also be changed at predetermined intervals, so that it would rotate first clockwise and then counter-clockwise. This change in direction could then be repeated as often as desired.
  • this is the lower part 40 of a hard gelatine capsule.
  • the lower capsule part 40 is positioned below the dosing chamber 24 by means of a receiving unit 42 .
  • the lower capsule part 40 can be removed laterally by the receiving unit 42 so that a new lower capsule part can be positioned under the dosing chamber 24 .
  • the filled lower capsule part 40 can then be provided with another pellet or another product in further processing stations, or it can also be closed directly.
  • the supply and removal of Capsule bottoms can be done in particular by a rotary indexing table, as for example from the EP 1 415 637 A1 or the EP 2 135 810 A1 is known.
  • the ram 20 is caused to rotate (arrow 44) by the drive unit 32 while the compact 30 is being ejected.
  • the rotation 44 of the stamp 20 during the ejection of the compact 30 detaches the compact 30 more easily from the underside of the stamp 20 and can fall into the lower capsule part 40 safely and reliably.
  • the rotational movement 44 can take place in a manner comparable to the rotational movement 34 with a constant rotational speed and direction, but also with a varying rotational speed and/or rotational direction. It would be possible to use both the rotational movement 34 during compacting ( 1 ) as well as the rotational motion 44 during ejection ( 2 ) to perform. In this case, the two rotational movements 34, 44 can be identical, but they can also be executed differently, adapted to the different situations. However, depending on the filling material used, the cycle speed of the rotary indexing table and/or the size of the compact 30, it may be sufficient to provide only the rotary movement 34 during the compaction of the filling material or the rotary movement 44 during the ejection of the compact 30 from the dosing chamber 24.
  • a device 12 not belonging to the invention is in Figures 3 and 4 shown.
  • the device 12 has a plunger 50 as a dosing tool, which can be set in a vertical lifting motion (arrow 52) by means of a motor drive, not shown here. Due to the lifting movement 52, the pipette 50 moves downwards into the filling material 56 present in a filling material container 54 and upwards out of it again.
  • the siphon 50 has an outer dosing sleeve 60 and a dosing piston 62 movably guided therein.
  • the dosing piston 62 is retracted a little from the free edge 64 of the dosing sleeve 60, so that a dosing chamber 66 is formed within the dosing sleeve 60.
  • the dosing sleeve 60 is in 3 is immersed with its free edge 64 in the filling material 56 that is present in the filling material container 54 and forms a powder bed. When the siphon 50 is immersed, the dosing chamber 66 is filled with the filling material 56.
  • the dosing piston 62 of the siphon 50 in the embodiment shown here is set in rotation by a drive unit 70 (arrow 72).
  • This rotation 72 of the dosing piston can ensure that the filling material 56 is distributed evenly in the dosing chamber 66, so that an optimal and reproducible filling of the dosing chamber 66 is achieved.
  • the rotational movement 72 takes place at a constant speed in the clockwise direction.
  • the rotational movement 72 could also take place in a counter-clockwise direction.
  • the speed during the rotational movement 72 could be varied.
  • the rotational movement could consist of several smaller, jerky movements.
  • the direction of rotation could also be changed at predetermined intervals, so that it would rotate first in a clockwise direction and then in a counter-clockwise direction. This change in direction could then be repeated as often as desired.
  • the amount of powder predetermined by the volume of the dosing chamber 66 remains in the dosing chamber 66 when the pipette 50 is pulled out of the powder bed. In this way, the powder can be transported with the siphon 50 and filled out of the dosing chamber 66 into a container provided for this purpose by means of the dosing piston 62 (see Fig 4 ). In the present example, this is the lower part 40 of a hard gelatine capsule was positioned below the lancing siphon 50 by means of a receiving unit 42 . In the present example, the dosing piston 62 of the siphon 50 is caused to rotate (arrow 74) by the drive unit 70 during the ejection of the powder present in the dosing chamber 66 . Due to the rotation 74 of the dosing piston 62 during the ejection of the powder, the dosing chamber 66 can be emptied quickly and completely.
  • the rotational movement 74 can take place in a manner comparable to the rotational movement 72 with a constant rotational speed and direction, but also with a varying rotational speed and/or rotational direction. In this case, it would be possible both the rotational movement 72 during the immersion of the pipette 50 into the filling material 56 ( 3 ) as well as the rotational movement 74 during the ejection of the powder ( 2 ) to perform. In this case, the two rotational movements 72, 74 can be identical, but they can also be executed differently, adapted to the different situations. However, it can also be sufficient to merely provide the rotational movement 72 during the immersion of the pipette 50 into the filling material 56 or the rotational movement 74 during the ejection of the powder from the dosing chamber 66 .
