Problems solved by technology

However, the higher motion speeds in the case of industrial-scale dosing conflict with this static process
Therefore, the often necessary 100% process control (In-Process-Kontrolle) can only be realized with difficulty and at high cost

Embodiment Construction

[0020] figure 1 and 2 Schematic sectional views of a metering device according to the invention in two different configurations are shown in an overview. In addition to the schematically delineated dosing unit 16 ( figure 2 ), the dosing device according to the invention comprises a capacitive measuring system 1 and a calibration device 2 for the capacitive measuring system 1 ( figure 1 ). The dosing device is designed for dosing especially fixed pharmaceutical dosing units 9 ( figure 2 ), with regard to the actually obtained quality of the individual dosing units 9 is detected and transported into the target container 17 . The medical administration unit 9 mentioned can be a tablet, a pill, a compressed powder plug or the like. As target container 17 ( figure 2 ), blister packs, plug capsules or the like are conceivable, but intermediate containers, for example for reprocessing, are also conceivable.

[0021] First refer to figure 2 , in which the metering device ...

Abstract

The invention relates to a calibration device for a capacitive measuring system in a dosing device or a dosing device for, in particular, stationary medical dosing units, and an associated method for dosing. The calibration device comprises a test body, a drive means for the test body, and a drive for the test body with a first end position, with a second end position and with a guide section extending between the two end positions. The guiding device, and wherein the drive means are designed for reciprocating movement of the test body along the guiding section between the two end positions. The capacitive measuring system is calibrated by means of a calibration device. The dosing unit is then dosed by means of the dosing device and is checked here with respect to the mass of the prescribed dose by means of a calibrated capacitive measuring system.

Description

technical field [0001] The invention relates to a calibration device for a capacitive measuring system, a dosing device (Dosiereinrichtung) with a capacitive measuring system and with a calibration device, and a method for dosing by means of the mentioned dosing device In particular the method of fixed pharmaceutical administration units (Darreichungseinheit, sometimes also called administration units). Background technique [0002] For example in the field of medicine it is important to precisely and reproducibly dose dosage units so that the patient takes exactly the set amount of active ingredient. Fixed administration forms can be, for example, tablets or powdered doses provided in push-in capsules or pellets. Of course, any other solid form of administration is also conceivable. In any case, the dosing of such dosing units is usually carried out volumetrically, in which a defined target mass is aimed at via a defined measured volume and density of the material. Ultim...
