Definitions

  • the invention relates to a device for dosing and filling of powdery contents into containers according to the preamble of claim 1, according to DE 10, 2014 200 484 A1 and DE 102 51 065 A1 .
  • a device with the features of the preamble of claim 1 is from DE 10 2008 040 595 A1 known to the applicant.
  • the known device has a dosing wheel which is rotatably mounted on a horizontal axis, with a plurality of dosing chambers being formed in the dosing wheel for filling a specific quantity of filling material in each case.
  • the dosing chambers overlap with a filling material container, from which the powdered or granulated filling material is delivered into the dosing chamber.
  • the release of the filling material from the filling material container into the respective dosing chamber is supported by negative pressure, which is applied to the dosing chamber via a bore.
  • the filling material is released from the metering chamber into a container arranged below the metering chamber.
  • the release of the filling material is supported both by a vibration generator and by a compressed air source, with the compressed air source acting on the dosing chamber via the same bore as the vacuum source during the filling process.
  • the compressed air introduced via the bore into the area of the dosing chamber flows through a filter element forming the bottom area of the dosing chamber. The compressed air thus acts over the entire cross section of the dosing chamber in order to support the emptying of the filling material from the dosing chamber.
  • More device for dosing and filling of powdered contents in containers are from DE 197 34 109 A1 and the DE 2 231 040 A1 known.
  • the device according to the invention for dosing and filling of powdery filling material in containers with the features of claim 1 has the advantage that through targeted guidance of the compressed air, the compressed air acts at least essentially on the area of the (peripheral) wall delimiting the dosing chamber and thus acts in a targeted manner the wall area of the dosing chamber is freed from any filling material that may be adhering.
  • the targeted guidance of the compressed air in the region of the wall of the dosing chamber thus makes it possible for a relatively low overpressure or relatively low mechanical or pneumatic energy originating from the compressed air to be sufficient for cleaning or keeping the wall of the dosing chamber free of filling material , to prevent filling material from sticking in the dosing chamber.
  • the cleaning or removal of filling material from the wall of the dosing chamber has the particular advantage that incorrect dosing, in particular underdosing, is ruled out, since the entire content of the filling material in the dosing chamber is dispensed into a container that is ready.
  • the compressed air outlet is at an oblique angle to a longitudinal axis of the dosing chamber in the area aligned with the wall of the dosing chamber.
  • a flow component is generated in the circumferential direction of the wall of the dosing chamber.
  • the cross section of the dosing chamber is circular and that the at least one compressed air outlet is arranged radially inside the cross section.
  • a dosing chamber with a round cross section prevents in particular the formation of dead spaces that promote the adhesion of the filling material in the area of the dosing chamber.
  • a filter element is arranged in the area of the compressed air outlet.
  • a filter element can be designed, for example, in the form of a sintered metal element. In addition, it reliably prevents contamination of the compressed air bore or compressed air outlet by filling material.
  • the at least one compressed air borehole is arranged in the area of a format change part and can be pneumatically connected to a stationary supply borehole via a feed borehole that preferably runs perpendicular to the at least one compressed air borehole .
  • the device with the features of dependent claim 6 is characterized in that at least the beginning and the end of the compressed air blast is adapted to the filling material and/or the target quantity of filling material by means of a control device.
  • this makes it possible to introduce the compressed air blast into the dosing chamber only during the period of time in which the dosing chamber is aligned with the container. In this way, in particular, the contamination of the device with filling material is also reduced.
  • the level of the pneumatic pressure and/or the pressure profile of the compressed air blast can also be adapted to the filling material and/or the target quantity of filling material. It is thus possible, for example, to linearly increase the pressure of the compressed air blast from an initial value to a maximum value and then decrease it again to a final value.
  • An increased pressure of the compressed air can also be provided, for example, in the case of a filling material having a particularly small particle size, in order to enable reliable cleaning of the wall of the dosing chamber.
  • the one in the 1 The device 10 shown in detail is used for dosing or filling powdered or free-flowing filling material 1 into container 2.
  • the filling material 1 can be, in particular and not restrictively, a pharmaceutical product or a pharmaceutical active substance.
  • the container 2 is, for example, a small bottle, a vial or the like.
  • the device 10 has a reservoir 11 for the filling material 1, shown only partially, on the base of which in the area of an approximately annular recess a blow-out element 15 designed as a format-changing part is interchangeably inserted. That in the 2
  • the blow-out element 15 shown in an individual representation serves to fill two containers 2 at the same time and has a through hole 16 and on the side facing away from the storage container 11 on a pitch circle diameter around the through hole 16 two kidney-shaped extensions 17 .
  • a total of four through-openings 18 , 19 running axially parallel to the through-hole 16 are formed in the blow-out element 15 , with two through-openings 18 , 19 being provided in the region of each extension 17 .
  • the compressed air holes 22 are in the 3 recognizable, common feed bore 23 which runs at right angles to the longitudinal axes of the four compressed air bores 22 .
  • the feed hole 23 opens into a side wall of the extension 17 and is aligned there with a supply bore 24 which is connected to a compressed air source 25.
  • the compressed air source 25 can be controlled by a control device 28 .
  • the control device 28 is designed to generate either a constant pressure p of the compressed air in the supply bore 24 and thus in the four compressed air bores 22, or a pressure curve that is variable both in terms of level and over time, by appropriate activation of the compressed air source 25 .
  • a 2-part metering disc 30 is arranged so that it overlaps with the blow-out element 15 ( 1 ).
  • the two elements 31, 32 of the metering disk 30 are arranged coaxially to one another and can be moved back and forth about a common axis of rotation 34 in the direction of the double arrow 35 by means of a drive, not shown, in an oscillating manner by a specific angle of rotation.
  • the axis of rotation 34 is aligned with the longitudinal axis 36 of the through hole 16 of the blow-out element 15.
  • two metering bores 38, 39 are formed as through-holes in the region of overlap with the projections 17.
  • a sleeve-like extension 41 of the element 31 dips into the dosing bore 39 of the element 32 ( 1 ).
  • the two dosing bores 38, 39 delimit a dosing chamber 42.
  • the volume of the dosing chambers 42 can be adjusted by an axial adjustment of the two elements 31, 32.
  • the dosing bores 38, 39 are arranged on the same pitch circle diameter around the longitudinal axis 36 of the through-bore 16 of the blow-out element 15 as the through-openings 18, 19.
  • the angular distance between the dosing bores 38, 39 in the area of the extension 17 corresponds to half the angular distance between the through-openings 18, 19 or the angular distance between the respective passage opening 18, 19 and the area of the four compressed air outlets 21. This makes it possible that in the two reversal points of the oscillating movement of the metering disk 30, two metering bores 38, 39 overlap with the Passage openings 18, 19, and two other dosing bores 38, 39 overlap with the compressed air outlets 21 of four compressed air bores 22.
  • the feed plate 45 On the side of the metering disk 30 facing away from the blow-out element 15 there is a stationarily arranged feed plate 45 with two through-holes 46 .
  • the two through bores 46 are aligned with the area of the four compressed air outlets 21 and have a diameter which corresponds at least to the diameter of the dosing bore 39 .
  • the through holes 46 are arranged in alignment with the containers 2 .
  • the feed plate 45 forms a (lower) boundary of the metering chamber 42 with the side facing the metering chamber 42 of the metering disk 30.
  • the four compressed air outlets 21 are arranged to overlap with the cross section of the dosing chamber 42 . Furthermore, the compressed air outlets 21 are arranged near the wall 47 of the dosing bore 38 or the dosing chamber 42 .
  • the alignment of the compressed air outlets 21 is such that the compressed air flowing out of the compressed air outlets 21 strikes the wall 47 of the dosing chamber 42 at least essentially directly or sweeps along it in order to remove any filling material 1 adhering there.
  • the four compressed air bores 22 have a corresponding length and orientation in order to align the flow of compressed air accordingly. The alignment of the longitudinal axes of the compressed air bores 22 therefore runs at an oblique angle thereto in order to generate a component of the compressed air in the circumferential direction of the wall 47 .
  • the compressed air bores 22 or the compressed air outlets 21 are preferably arranged at least approximately at equal angular distances from one another in relation to the longitudinal axis 48 of the dosing bores 38, 39. Furthermore, the diameters of the compressed air bores 22 and the compressed air outlets 21 are preferably of the same size. In the area of the compressed air outlets 21, filter elements or air guiding elements, for example in the form of sintered metal inserts, can also be provided (not shown).
  • the filling material 1 is emptied from the respective dosing chamber 42 essentially by gravity.
  • the compressed air blast introduced into the dosing chamber 42 via the compressed air outlets 21 causes any filling material 1 adhering to the wall 47 to be removed by the compressed air or the compressed air blast and discharged into the container 2 together with the remaining filling material 1 .
  • the dosing disk 30 In the 4 a position of the dosing disk 30 is shown in which the one dosing chambers 42 are arranged in overlap with the passage openings 18 so that these dosing chambers 42 are filled with filling material 1 from the reservoir 11 . At the same time, the other dosing chambers 42 overlap with the compressed air outlets 21 so that these dosing chambers 42 are emptied or cleaned of any filling material 1 adhering to their walls 47 .
  • FIG. 5 an intermediate position of the metering disk 30 is shown, in which one metering chamber 42 partially overlaps the passage openings 19 , while the other metering chambers 42 partially overlap the region of the compressed air outlets 21 .
