Definitions
- the invention relates to a filling device for volumetri- see dosing of powder, in particular for dosing powdery drug.
- a previously known form of volumetric metering is carried out with a so-called roller metering device, in which a cylindrical roller has one or more rows of calibrated metering chambers. These are filled with powder using vacuum. Subsequently, the roller is rotated with the filled metering chambers in an overhead position in which the powder is blown out of the metering chambers in the individual containers provided.
- the resulting dosing accuracy is sufficiently exact for most applications. However, the processing speed is not always satisfactory.
- it is necessary that the containers are aligned in a row corresponding to the row of metering chambers of the roll. Deviating container arrangements, for example in a circular arrangement, can not or only with difficulty be filled with the metering roller.
- EP 0 474 466 B1 discloses a device and a method for filling dosing containers, the dosing containers being provided directly by the storage containers provided for the user for use in the form of storage containers
- Blisters are formed.
- the blisters have a fixed individual volume and are dipped overhead in a powder bed, where they are completely filled with the measure of their predetermined volume. Volumetric metering of the powder and filling of the blisters take place in one operation. After dosing and filling, the blisters are sealed and ready for use.
- the invention has for its object to provide a filling device for volumetric dosing of powder, in particular powdery drug with increased efficiency and process reliability.
- the invention relates to a filling device for volumetric metering of powder, in particular of powdered medicament, comprising a metering container with an inner space and an edge circulating around a filling opening of the metering container, a permeable, but powder-impermeable and flat retaining device, which is filled during filling of the metering container covering the filling opening and the edge, a filling line, which is passed through the retaining device, and which opens when filling the dosing into the interior, and means for generating a pressure difference across the retaining means.
- the abovementioned arrangement permits the economic filling and volumetric metering of powder at high processing speed with high process reliability: by means of the pressure difference applied to the retaining device with relatively elevated pressure in the interior of the metering container or with reduced pressure on the opposite side Outside the retaining device, the powder is introduced through the filling line into the interior of the dosing and retained there by the retainer. The pressure difference is maintained at least until the interior of the dosing tank is completely filled with the powder.
- the volume defined or limited by the shape of the dosing container and by the retaining device precisely predetermines the volume of powder to be filled. Since the retention device not only covers the filling opening, but also the edge of the dosing, there is no contamination of the edge by powder. After removal of the retainer no reworking of the edge and the powder surface is required, for example by doctoring.
- the respective dosing can be filled to the brim with high process speed and high dosing accuracy and sealed if necessary without further intermediate steps.
- the retaining device is designed as a membrane with transversely through the membrane passed, separated gas channels.
- the separation of the gas channels from each other in the direction of the plane of the membrane allows a flow across the membrane surface, without a flow takes place in the direction of the membrane surface.
- the retaining device is designed elastically deformable transversely to its surface, wherein the filling line is firmly connected to the retaining device. It is a level control of the powder in the interior of the dosing by lifting or lowering the filling line by utilizing the elastic Compliance of the restraint provided.
- the filling line embodied, for example, as a dip tube may, if required, be immersed more or less far into the interior of the dosing container when the restraint device is resting against the container or pulled out of it. Density-
- Variations of different powder batches, volume fluctuations of the individual dosing or the like can be compensated in a simple manner. In any case, an adjustment of the filling volume to the respective needs in a simple manner possible.
- the filling line is displaceably guided in its longitudinal direction through the retaining device, wherein a level control of the powder is provided in the interior of the dosing by inserting or pulling out of the filling line in the implementation of the retaining device.
- a level control of the powder is provided in the interior of the dosing by inserting or pulling out of the filling line in the implementation of the retaining device.
- the retaining device continuously covers a plurality of dosing containers.
- a plurality of containers can be filled simultaneously, which significantly increases the filling throughput and thus the economy of the arrangement. It is not or only limited to the mutual alignment of the individual dosing each other. This allows a needs-based, almost any relative arrangement of the dosing, for example in matrix or circular, but other, custom arrangements are readily coverable. All arrangements can be filled more or less simultaneously, which contributes to increasing the economy.
- filling lines per metering container are passed through the retaining device. This makes it possible to fill even containers with irregular floor plan brimming. Customized container shapes, for example, with corners or angles can be filled gap-free by adapted arrangement of the filling lines with high process reliability.
- the retaining device is circumferentially pressed against the edge of the dosing container by means of a contour-flush, in particular elastic pressure frame, towards the edge of the dosing container.
- a sealing of the container interior is reliably ensured, wherein the elastic configuration of the An horrrahmens compensates for dimensional tolerances in the region of the container edge.
- the retaining device covers the filling opening completely exposed to the edge, without dead areas arise. Even in the edge areas, a gap-free powder filling takes place, which contributes to the precision of the volumetric dosage.
- the retaining device circumferentially by means of a flat, the edge and the filling opening overlapping, air-permeable and in particular elastic pressure plate to the edge of the dosing is pressed.
- the elastic pressure frame is thereby achieved that the arrangement is not tied to the format of the respective dosing. Without changes or adaptations of the pressure plate to the contour of the respective dosing containers to be filled, filling work with changing container shapes can be carried out.
- the abovementioned means for generating the pressure difference at the retaining device can have, for example, an overpressure source, by means of which the powder is blown through the filling line into the interior of the respective metering container.
- a chamber open to the retention device, but otherwise closed is arranged for the formation of the means for generating the pressure difference on the side facing away from the dosing container, wherein the chamber has a connection to the vacuum source.
- the chamber is connected to the vacuum source so that a negative pressure builds up in it.
- the powder supply there is atmospheric pressure, as a result of which the desired pressure difference is established at the retention device. This leads to the fact that the powder is sucked from the supply through the filling line into the container interior.
- the retention chamber may have a connection to an overpressure source. After filling, a short backwashing may be carried out, if necessary, by means of which the retention device is freed of adhering or partially sucked-in powder.
- the dosing container is a storage container provided for later sealing. Without further intermediate measures so a dosage of the powder takes place directly in the storage container. The cover of its edges with the retaining device keeps them free of powder, so that without further cleaning measures a direct sealing can take place, for example, by gluing or by welding on a film.
- the metering is a provided for later filling of the storage container metering chamber. This is of particular interest if the dosing volume should deviate significantly from the volume of the storage container. In each case results in a high processing speed with high process reliability and good economy.
