Definitions
- the invention relates to a filling arrangement for the volumetric metering of fine-grained powder having the features according to the preamble of claim 1 and to a method for operating such a filling arrangement.
- Small amounts of powder, especially small amounts of medicinal powder or powdered medicament, for example, for pulmonary or transdermal administration, must be measured and packaged in user-suitable single doses of a few milligrams or even micrograms. Such a measurement by weighing is difficult, which is why a volumetric metering is widely used in such applications.
- a previously known form of volumetric dosing is carried out with a so-called membrane dosing device, which is known, for example, from WO 2009/046728 A1.
- a metering container for receiving the powder for example in the form of a blister pack or the like, is provided with an interior space, with a filling opening and with an edge running around the filling opening.
- a filling device adapted thereto has a cover in the form of an air-permeable membrane, which is used during filling of the membrane
- Dosage container the filling opening and its edge covers. Furthermore, a filling line for the powder is provided, which is passed through the membrane and opens when filling the dosing into its interior. To generate the filling process, an air pressure difference is applied to the air-permeable membrane, which creates a negative pressure through the membrane in the interior of the dosing. By means of this negative pressure, the powder from the filling line is sucked into the dosing.
- the membrane is so fine-pored that although it can be flowed through to generate the negative pressure with air, but that the entering into the interior of the dosing powder is retained and remains in the interior.
- the arrangement shown has worked well for a full filling of the dosing.
- the individual quantities of the powder can be exactly metered.
- the edge surrounding the filling opening is covered by the membrane during the filling process, so that no powder can settle here.
- the edge can be used without further purification
- Sealing surface can be used for the later sealing of the dosing with sealing film.
- the invention has the object of developing a generic filling arrangement such that you
- the invention is further based on the object of specifying a method for operating said filling arrangement, with which a simplified and exact process-reliable metering of the powder is possible.
- At least one pressure line is provided, which is passed through the cover, and which opens when filling the dosing into its interior, and that a Druckpulsationsein- direction to generate a by the atmospheric pressure atmospheric pressure as a mean value provided is, and wherein the oscillating pressure is transmitted through the pressure line in the interior of the dosing.
- the powder is provided in a supply container arranged on the input side of the filling line and in the filling line itself in such a manner that the powder does not fall through the filling line due to its own weight.
- the metering container is brought with its filling opening under the cover of the filling device such that the sealing portion of the cover sealingly abuts the edge of the metering, and that the filling line and the pressure line open into the interior of the metering.
- the embodiment according to the invention achieves several advantages at once: the pressure oscillating around the ambient atmospheric pressure as an average and introduced into the dosing container leads, on account of its mean value, to the fact that on average neither air flows in nor out of the dosing container.
- the fine-grained powder tends to agglomerate the more fine-grained it is.
- the embodiment according to the invention is suitable in particular for powders having a particle size in the range of 1 ⁇ m to 80 ⁇ m inclusive, with medicinal powders frequently representing a mixture of different types of powder.
- the medically effective constituents in this case have a typical particle size range of from 1 .mu.m up to and including 20 .mu.m, wherein a granular support material having a particle size range of from 30 .mu.m up to and including 80 .mu.m or even up to and including 200 .mu.m is admixed.
- a free cross-sectional dimension of the filling pipe is matched to the 'characteristics of the powder that the powder when switched Druckpulsationseinrich- tung not due to its own weight by the filling line fall through, but rather gets stuck there due to its pronounced agglomeration tendency.
- the powder stuck in the filling line is fluidized by overcoming the cohesive forces, so that it falls due to its own weight from the filling line into the interior of the dosing.
- the powder delivery is set in the container interior in motion and stopped by switching off the pulsating pressure immediately, allowing an exact dosage.
- a free cross-sectional dimension, the filling line in a range of from 0.1 mm to 5.0 mm inclusive, expediently in a range of 0.5 mm to 2.0 mm inclusive, and preferred in a range of 1.0 mm to 1.5 mm inclusive, has been found to be advantageous.
- a special feature of the invention is that the application of the pulsating pressure to the powder from the side of the metering container or the interior of the latter takes place.
- This arrangement is based on the recognition that the powder has a high internal damping against externally applied mechanical vibrations as a two-phase mixture of powder grains and air due to internal friction.
- this damping is meaningless for the filling process.
- the powder is fluidized exactly where an independent outflow from the filling line is required. As the degree of drainage increases, the solids-like compacted front of the powder migrates backwards towards the reservoir, but always remains at pulsating pressure regardless of its spatial location. Accordingly, a local fluidization always takes place where it is required, namely on the powder front facing the dosing, from which the individual powder grains are to be removed.
- the pressure amplitudes can be kept small, which helps to protect the often sensitive fine-grained powder.
- Pressure can be adjusted almost arbitrarily to the particular powder consistency to be processed, so that a wide range of powders can be filled.
- the fluidization takes place solely by the oscillating pressure without mechanically moving components being required or used.
- the sensitive powder is not damaged.
- By eliminating mechanically moving components no abrasion, which could contaminate the powder. Since the air balance is balanced and there is no mean flow, there is no risk of segregation of the pulse. vers, so that also readily multiphase powder types can be filled.
- the amplitude, frequency and duration of the oscillating pressure can be set in a manner and used, in the target container or in the dosing desired powder densities with specific compression ratios and thus precisely determined
- Another advantage of the embodiment of the invention is the ability to make either a full or even a partial filling of the dosing.
- This can be done in different ways: First, in an advantageous development of the filling arrangement, the cover in the region of the filling opening of the dosing a cover portion and in the region of the edge of the dosing have a sealing portion, wherein the lid portion is offset in height relative to the sealing portion. If the lid portion is offset in height in the interior of the dosing, the free volume of the container interior is reduced. The reduced volume can then be completely filled with powder. After removal of the filled dosing but is based on the peripheral edge an air-filled additional volume, which results in sealed edge according to user request defined sub-filling. Conversely, it may also be possible to offset the cover portion of the cover relative to the sealing portion from the interior of the dosing out, whereby a targeted overfilling is possible.
- the exact dosage can be made in different process variants: First, it may be appropriate be that the limited by the lid portion of the cover interior of the dosing is completely filled with the powder, wherein after complete filling of the oscillating pressure is switched off.
- the amount of powder is defined volumetrically exactly by the geometry of the dosing and the lid portion.
- the interior of the dosing container which is limited by the cover section of the cover, is only partially filled with the powder, and that timed filling is carried out.
- the oscillating pressure is switched off, as a result of which the powder flow is interrupted in a time-controlled manner even before the interior of the dosing container is completely filled relative to the cover.
- the pressure line is passed coaxially through the filling line, so that the filling line has a Ringguer bain.
- the pulsating pressure provided by the pressure line is provided directly at the container-side powder opening of the filling line, so that a precisely defined interaction between the pulsating pressure and the powder occurs.
- the container-side pressure opening of the pressure line may be expedient to arrange the container-side pressure opening of the pressure line at a height offset relative to the container-side suction opening of the filling line, relative to its axial direction.
- the powder opening and the pressure opening are preferably in the ready-to-use position. pulled in the direction of gravity at the same level, which improves the previously described interaction between the pulsating pressure and the powder thus acted upon.
- the coaxial design of the pressure line and filling line also leads to the fact that adjusts a large ratio of cross-sectional area to the free lateral cross-sectional dimension in the filling line due to their annular cross-sectional shape.
- the latter specifies the adhesion of the non-fluidized powder in the filling line, so that the filling line can be provided with an overall large cross-sectional area without the powder tending to flow through on its own.
- a comparatively large amount of powder can pass through, which accelerates the filling process and thus increases the number of cycles and the economy of the arrangement.
- the powder is stored on the input side of the filling line in a storage container, wherein a substantially constant atmospheric pressure prevails above the powder stored in the storage container.
- a substantially constant atmospheric pressure prevails above the powder stored in the storage container.
- the pulsating pressure has the ambient atmospheric pressure as the mean pressure, the mean pressure difference between the powder top side and the powder bottom side is equal to zero, so that undesired air flow through the filling line is prevented.
- the pressure line is an air line for transmitting oscillating air pressure, whereby the structure can be kept simple as a whole and is suitable and economical to use for the greater part of the powders to be processed.
- a vibrating membrane is provided for this purpose. This is structurally simple in construction and suitable for reliable continuous operation. According to the principle of a loudspeaker diaphragm, it can be driven electromechanically in a simple manner, for example.
- Filling and volumetric dosing may be carried out directly in metering containers intended for the end user and user, such as blisters, capsules or the like. respectively.
- the dosing is a calibrated with respect to the volume of its interior transfer chamber. The amount of powder measured by the calibrated volume is transferred from the transfer chamber to the final packing unit such as blister, capsule or the like. In this way, an exact dosage can be brought about without having to set too high demands on the dimensional accuracy of the blisters, etc.

- Position performs a translational vibration represented by dashed lines.
- a vibration form with a total of oscillating membrane 16 moved laterally transversely to its plane may also be expedient.
- the oscillatory pressure p generated by the pressure pulsation device 10 or the vibration diaphragm 16 is transmitted from the pressure pulsation device 10 through the pressure line 9 and through the cover 7 into the interior 4 of the dosing container 3.
- the metering container 3 is designed as a one-sided open and otherwise closed container, wherein the open Side in the form of a filling opening 5 with respect to the gravitational force direction comes to lie up.
- the filling opening 5 is enclosed by a peripheral edge 6.
- the metering container 3 is formed separately from the stationarily constructed filling device 1 and movable relative thereto. For the filling process, the metering container 3 is moved with its filling opening 5 under the cover 7 of the filling device 1 in such a way that the cover 7 is sealed with a sealing section 14 surrounding a container-side powder opening 11 of the filling line 8 and a container-side pressure opening 12 of the pressure line 9 encircling edge 6 of the dosing 3 rests.
- the pressure p generated by the pressure pulsation device 10 is shown schematically in the diagram of FIG. 2, wherein the curve of the pressure p over the time t is shown.
- the oscillating pressure p has a maximum amplitude a, by means of which it oscillates around the atmospheric pressure po as an average value.
- a substantially constant atmospheric pressure po prevails above the powder 2 stored therein and is thus equal to the mean value of the oscillatory pressure p introduced into the interior 4 of the metering container 3 by means of the pressure line 9.
- a pressure equilibrium prevails above and below the powder 2. Accordingly, a balanced pressure balance arises in the interior 4, so there is no continuous flow. Local air flows are limited to the periodic, but in sum, balanced entry and exit of air through the pressure opening 12.
- the pressure pulsation device 10 For filling the dispensing container 3 which has been brought into the position according to FIG. 1, the pressure pulsation device 10 is put into operation.

- the dosing container filled in this way is then removed and sent for further processing.
- Dosing 3 only partially filled with the powder 2 len. This can be done by determining the time t 2 required for the partial filling and switching off the oscillating pressure p (FIG. 2) at this time t 2 . After this time-controlled partial filling then the dosing 3 is removed under the filling device 1 and fed to the further processing. Finally, there is still the possibility shown in FIG. 1 of generating a fill level that deviates from the volume of the interior 4. For this purpose, the cover section 13 is transversely offset relative to the sealing section 14 surrounding it, transversely or perpendicularly to the plane of the filling opening 5.
- the height offset is selected such that the cover section 13 protrudes into the interior 4 of the dosing container 3 relative to the edge 6 and thereby reduces this relative to the nominal volume predetermined by the plane of the edge 6.

- the radially inner pressure line 9 is annularly surrounded by the radially outer filling line 8. While the pressure line 9 has a circular cross section, the free cross section of the filling line 8 is annular. But it may also be appropriate to reverse embodiment in which the filling line 8 extends within the pressure line 9.
- the above-described free cross-sectional dimension b of the filling line 8 here is the radius difference between the inner radius of the filling line 8 and the outer radius of the pressure line 9.
- the cross-sectional dimension b is to be chosen such that the powder 2 provided in the storage container 15 and also in the filling line 8 and not acted upon by the oscillating pressure p does not drop or fall out of the filling line 8 due to its own weight rather there it gets stuck due to its agglomeration properties, but that a flow out of the powder 2 occurs as soon as the oscillating pressure p acts.
