BeschreibungDescription
Die Erfindung betrifft eine Dosiereinheit für flüssige Pharmazeutika nach dem Oberbegriff des AnspruchsThe invention relates to a dosing unit for liquid pharmaceuticals according to the preamble of claim
Eine derartige Dosiereinheit ist bereits allgemein bekannt und besteht aus einem Zylindergehäuse und Anschlüssen zum Zuführen und Abführen des Pharmazeutikas, welche jeweils für sich als separate Bauteile spanend hergestellt sind. Anschließend werden die Anschlüsse durch eine Schweißverbindung an dem Zylindergehäuse befestigt. Nachteilig dabei ist, dass durch die Schweißverbindung im Übergangsbereich zwischen den Anschlüssen und dem Zylindergehäuse die Gefahr einer Lunkerbildung und eine damit einhergehende Korrosion besteht. Ferner kann es infolge von Schweißspannungen zur Qualitätseinbußen kommen. Zuletzt besteht die Gefahr, dass es aufgrund unterschiedlicher Materialchargen, welche zur Herstellung des Zylindergehäuses und der Anschlüsse verwendet wurden, im Zusammenhang mit den beim Schweißen verwendeten Schweißzusätzen zu Inhomogenitäten in der Materialqualität kommt.Such a dosing unit is already generally known and consists of a cylinder housing and connections for supplying and discharging the pharmaceutical, each of which is machined as a separate component. The connections are then attached to the cylinder housing by a welded connection. The disadvantage of this is that the welded connection in the transition area between the connections and the cylinder housing poses the risk of voids forming and the associated corrosion. Furthermore, welding stresses can lead to a loss of quality. Finally, there is a risk of inhomogeneities in the material quality due to different material batches used to manufacture the cylinder housing and the connections in connection with the welding consumables used during welding.

Aufgabe der Erfindung ist es daher, die oben genannten Nachteile bei der Herstellung einer Dosiereinheit für flüssige Pharmazeutika zu vermeiden. Diese Aufgabe wird bei einer Dosiereinheit für flüssige Pharmazeutika mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst. Dadurch, dass die Anschlüsse zusammen mit dem Zylindergehäuse einstückig durch einen spanenden Fertigungsprozess hergestellt sind, werden nicht nur die beim oben genannten Stand der Technik genannten Nachteile vermieden, vielmehr ergibt sich durch die Reduzierung der Fertigungsschritte auch ein Kostenvorteil bei der Herstellung einer erfindungsgemäßen Dosiereinheit für flüssige Pharmazeutika.The object of the invention is therefore to avoid the above-mentioned disadvantages in the production of a dosing unit for liquid pharmaceuticals. This object is achieved in a dosing unit for liquid pharmaceuticals with the characterizing features of claim 1. Because the connections are manufactured together with the cylinder housing in one piece by a machining process, not only are the disadvantages mentioned in the above-mentioned prior art avoided, but the reduction in manufacturing steps also results in a cost advantage in the production of a dosing unit according to the invention for liquid pharmaceuticals.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend näher erläutert. Die einzige Figur zeigt eine erfindungsgemäße Dosiereinheit für flüssige Pharmazeutika in einer perspektivischen Darstellung.An embodiment of the invention is shown in the drawing and is explained in more detail below. The single figure shows a dosing unit according to the invention for liquid pharmaceuticals in a perspective view.
0 Die in der Figur dargestellte Dosiereinheit 10 für flüssige Pharmazeutika ist Bestandteil einer nicht näher dargestellten Abfülleinrichtung, bei der mehrere Dosiereinheiten 10 in Reihe nebeneinander angeordnet sein können. Die Dosiereinheit 10 weist ein metallisches Zylindergehäuse 11 auf, aus dessen Unterseite ein Kolben 12 herausragt. Der Kolben 12 weist an seinem aus dem Zylindergehäuse 11 herausragenden Abschnitt eine umlaufende Ringnut 13 auf, an welcher ein ebenfalls nicht dargestellter Antrieb für den Kolben 12 befestigbar ist. Mittels des Antriebes kann der Kolben 12 im Zylindergehäuse 11 auf- und abbewegt werden. Durch die Auf- und Abwärtsbewegung wird das flüssige Pharmazeutika aus einem nicht dargestellten Vorratsbehälter angesaugt, und anschließend beispielsweise mittels einer Füllnadel einem zu befüllenden Behältnis 5 zugeführt.0 The dosing unit 10 for liquid pharmaceuticals shown in the figure is part of a filling device (not shown in detail), in which several dosing units 10 can be arranged in a row next to one another. The dosing unit 10 has a metal cylinder housing 11, from the underside of which a piston 12 protrudes. The piston 12 has a circumferential annular groove 13 on the section protruding from the cylinder housing 11, to which a drive for the piston 12 (also not shown) can be fastened. The piston 12 can be moved up and down in the cylinder housing 11 by means of the drive. The liquid pharmaceuticals are sucked out of a storage container (not shown) by means of the up and down movement and are then fed to a container 5 to be filled, for example by means of a filling needle.

Dazu sind am Zylindergehäuse 11 weiterhin ein erster rohrförmiger Anschluss 15 sowie ein zweiter rohrförmiger Anschluss 16 angeordnet. Über die beiden Anschlüsse 15, 16 sind Schlauchleitungen stülpbar, welche mit dem bereits angesprochenen Vorratsbehälter bzw. der Füllnadel verbunden sind. Die beiden Anschlüsse 15, 16 kommunizieren auf bekannte Art und Weise mit dem Innenraum des Zylindergehäuses 11. Weiterhin ragt aus der Oberseite des Zylindergehäuses 11 ein Drehschieber 17 heraus, welcher über einen Gabelkopf 18 im Zylindergehäuse 11 drehbar ist, um je nach Stellung des Drehschiebers 17 eine Verbindung entweder zwischen dem ersten Anschluss 15 und dem Innenraum des Zylindergehäuses 11, oder aber zwischen dem zweiten Anschluss 16 und dem Innenraum des Zylindergehäuses 11 herzustellen, so dass das flüssige Pharmazeutika in gewünschter Weise entweder angesaugt oder ausgestoßen werden kann. Zuletzt ist am Zylindergehäuse 11 auf der den beiden Anschlüssen 15, 16 gegenüberliegenden Seite ein Aufnahmebolzen 19 angeordnet, mit dem die Dosiereinheit 10 beispielsweise an einer Platte der Abfülleinrichtung befestigt werden kann. Die soweit beschriebene DosiereinheitFor this purpose, a first tubular connection 15 and a second tubular connection 16 are also arranged on the cylinder housing 11. Hose lines can be slipped over the two connections 15, 16, which are connected to the storage container or the filling needle mentioned above. The two connections 15, 16 communicate with the interior of the cylinder housing 11 in a known manner. Furthermore, a rotary slide valve 17 protrudes from the top of the cylinder housing 11, which can be rotated via a fork head 18 in the cylinder housing 11 in order to establish a connection either between the first connection 15 and the interior of the cylinder housing 11, or between the second connection 16 and the interior of the cylinder housing 11, depending on the position of the rotary slide valve 17, so that the liquid pharmaceutical can either be sucked in or expelled as desired. Finally, a mounting bolt 19 is arranged on the cylinder housing 11 on the side opposite the two connections 15, 16, with which the dosing unit 10 can be fastened, for example, to a plate of the filling device. The dosing unit described so far
10 mit ihren Bauteilen sowie deren Funktionsweise sind bereits allgemein bekannt.10 with its components and how they work are already generally known.
Erfindungswesentlich ist, dass zumindest das ZylindergehäuseIt is essential to the invention that at least the cylinder housing
11 und die beiden Anschlüsse 15, 16, bevorzugt jedoch auch der Aufnahmebolzen 19 zusammen mit dem Zylindergehäuse 11 aus einem einzigen Bauteil durch einen spanenden bzw. durch spanende Herstellungsprozesse hergestellt sind. Das bedeutet, dass beispielsweise das Zylindergehäuse 11 in dem Abschnitt 20, welcher sich unterhalb der beiden Anschlüsse 15, 16 sowie des Aufnahmebolzens 19 befindet, durch Drehen hergestellt ist, während der obere Teil des Zylindergehäuses 11 mit den daran einstückig angeformten Anschlüssen 15, 16 sowie dem Aufnahmebolzen 19 durch Fräs- sowie durch Dreharbeitsgänge hergestellt sind. Dadurch, dass die beiden11 and the two connections 15, 16, but preferably also the locating bolt 19 together with the cylinder housing 11 are made from a single component by a machining or machining manufacturing process. This means that, for example, the cylinder housing 11 in the section 20 which is located below the two connections 15, 16 and the locating bolt 19 is made by turning, while the upper part of the cylinder housing 11 with the connections 15, 16 formed integrally thereon and the locating bolt 19 are made by milling and turning operations. Because the two
- 4 - R. 303476- 4 - R.303476
Anschlüsse 15, 16 sowie bevorzugt auch der Aufnahmebolzen 19 einstückig mit dem Zylindergehäuse 11 aus einem Rohteil hergestellt sind, sind keine weiteren Verbindungstechniken zwischen den beiden Anschlüssen 15, 16 und dem Aufnahmebolzen 19 mit dem eigentlichen Zylindergehäuse 11 erforderlich.Since the connections 15, 16 and preferably also the locating bolt 19 are manufactured in one piece with the cylinder housing 11 from a blank, no further connection techniques are required between the two connections 15, 16 and the locating bolt 19 with the actual cylinder housing 11.
