Problems solved by technology

This is also difficult in the case of a doser with a horizontal closure when the filling has to be additionally compacted in the cavity to be filled.
In addition, an undesired reflow (nachrieseln, sometimes referred to as afterflow) of the filling material leaving the metering chamber cannot always be avoided

Embodiment Construction

[0033] Figures 1 to 4 A first exemplary embodiment of the metering device according to the invention is shown in a schematic longitudinal section in different successive method steps. The metering device is provided for volumetric metering of a flowable filling material, in particular a powder or granules 1 . The dry filler can be a detergent, cleaning agent or generally a cleaning agent, a pharmaceutical filler or, for example, also a nutritional supplement. Reference is made below by way of example to granules 1 , with all statements also applying to the other fillers. A partial quantity is dispensed from the larger quantity of granules 1 by means of the shown dosing device, is volumetrically dosed, and is transferred as the target quantity for dosing into the target cavity 23 . The target cavity 23 can be a deep-drawn, especially water-soluble film pack, a tube pack, a blister pack, a capsule, a machine opening of a tablet press, an intermediate container or any other r...

Abstract

The invention relates to a metering device for the volumetric metering of pourable material, in particular of pharmaceutical powder or pharmaceutical granular material (1). The metering device comprises a housing (2) and a metering slide (3) which can be moved relative to the housing (2), the housing (2) and the metering slide (3) together defining a metering chamber (4). The metering slide (3) is designed as a vertical slide which, in normal operating position, has a vertical stroke axis (5). The housing (2) has a guide surface (7, 7') for the metering slide (3), said surface running in the direction of the stroke axis (5). The metering slide (3) has a limiting surface (8, 8') which corresponds to the respective guide surface (7, 7') and rests slidingly on the guide surface (7, 7'). Starting from the limiting surface (8, 8'), a metering recess (9') is made in the metering slide (3), and / or starting from the guide surface (7, 7'), a metering recess is made in the housing (2). The metering chamber (4), in a stroke position of the metering slide (3), in which the metering recess (9, 9') is covered by the guide surface (7, 7') and / or the limiting surface (8'), is formed by the metering recess (9, 9'), the guide surface (7, 7') and / or the limiting surface (8').

Description

technical field [0001] The invention relates to a dosing device of the type specified in the preamble of claim 1 for volumetric dosing of flowable (rie self-hig, sometimes called slow-flow) filling materials. Background technique [0002] Volumetric dosing is widely practiced for dosing dry, flowable fillers such as powders, granules or the like, especially in the field of washing and cleaning agents, pharmaceuticals or nutritional supplements, by means of which Partial quantities of the quantity filling are drawn out volumetrically (abgrenzen) and thereafter transferred into the target cavity (container, capsule, etc.). [0003] In so-called chamber metering, a housing and a metering slide movable relative to the housing are provided for this purpose, wherein the housing and the metering slide together delimit the metering chamber. In this case, the filling material flows into the metering chamber whose volume determines the amount of powder or granules to be metered. A h...
