Abstract
Description
Stand der Technikwas standing of the technique
Die
Erfindung geht aus von einer Wiegeeinrichtung, insbesondere für pharmazeutische
Erzeugnisse wie Hartgelatinekapseln, Tabletten oder dergleichen,
nach der Gattung des unabhängigen
Anspruchs. Aus der
Der Erfindung liegt die Aufgabe zugrunde, eine mögliche Verschmutzung der Wiegeeinrichtung bei guter Reinigbarkeit zu reduzieren. Diese Aufgabe wird gelöst durch die Merkmale des unabhängigen Anspruchs.Of the Invention is the object of a possible contamination of the weighing device at good cleanability to reduce. This task is solved by the features of the independent claim.
Offenbarung der ErfindungDisclosure of the invention
Vorteile der ErfindungAdvantages of the invention
Eine Wiegeeinrichtung nach den Merkmalen des unabhängigen Anspruchs hat demgegenüber den Vorteil, dass die Wiegeeinrichtung selbst in staubiger, pulveriger Umgebung zu betreiben ist, ohne dass Pulver oder Staub in das Gehäuse bzw. in die Wiegezelle selbst dringt. Dadurch wird die Wiegegenauigkeit nicht in Mitleidenschaft gezogen. Dadurch, dass das Abdichtmtittel abnehmbar ausgebildet ist, kann das Gehäuse der Wiegeeinrichtung beispielsweise am Ende des Produktionsprozesses nass abgereinigt werden.A Weighing device according to the features of the independent claim has the other hand Advantage that the weighing device even in dusty, powdery Environment is to operate without powder or dust in the housing or penetrates into the load cell itself. This becomes the weighing accuracy not affected. Due to the fact that the sealing agent is designed removable, the housing of the weighing device, for example be wet-cleaned at the end of the production process.
In einer zweckmäßigen Weiterbildung ist vorgesehen, dass das Abdichtmittel eine Labyrinthstruktur aufweist. Eine solche Struktur gewährleistet einerseits, dass die Waagschale sich frei gegenüber dem Gehäuse bzw. der Messzelle im Gehäuse bewegen kann, andererseits jedoch die Verschmutzung zwischen Waagschale und Gehäuse bzw. Gehäuseinnerem erschwert wird. Andererseits lässt sich auch diese Labyrinthstruktur dank der Abnehmbarkeit des Abdichtmittels selbst leicht reinigen.In an appropriate training it is provided that the sealing means has a labyrinth structure. Such a structure is guaranteed on the one hand, that the weighing pan can move freely in relation to the housing or the measuring cell in the housing, On the other hand, however, the pollution between the weighing pan and housing or housing interior is difficult. On the other hand lets also this labyrinth structure thanks to the removability of the sealant even easy to clean.
In einer zweckmäßigen Weiterbildung ist das Abdichtmittel ringförmig ausgestaltet in der Weise, dass die Labyrinthstrukturen in Richtung des Gehäuses orientiert sind und einen u-förmigen Querschnitt aufweisen. In einer weiteren zweckmäßigen Weiterbildung ist ein weiterer Ring vorgesehen, der nicht mit den Abdichtmitteln in Verbindung steht und zwischen den zwei Labyrinthstrukturen angeordnet ist. Dadurch wird die Abdichtung gegen Verschmutzung von außen weiter verbessert.In an appropriate training the sealing means is annular designed in such a way that the labyrinth structures in the direction of the housing are oriented and a u-shaped Have cross-section. In a further expedient development is a further ring provided, which is not connected to the sealing means stands and is arranged between the two labyrinth structures. As a result, the seal against contamination from outside continues improved.
In einer zweckmäßigen Weiterbildung sind Dichtmittel vorgesehen, welche die Waagschale mit dem Gehäuse bzw. einer die Waagschale umgebenden Gehäuseumrandung abdichtend verbinden. Damit kann die Waagschale der Wiegeeinrichtung in eine Reinigungsposition gebracht werden, in der dank der Dichtung kein Schmutz von außen in den Spalt zwischen Waagschale und Gehäuse dringen kann. Bei abgenommenem Abdichtmittel kann die Wiegeeinrichtung gründlich gereinigt werden, ohne dass Schmutz oder Reinigungsmittel ins Innere der Wiegeeinrichtung dringen können.In an appropriate training sealing means are provided which the weighing pan with the housing or connect a housing surrounding the scale shell sealing. This allows the weighing pan of the weighing device in a cleaning position be brought in, thanks to the seal no dirt from the outside into the gap between balance pan and housing can penetrate. With removed sealant, the weighing device thoroughly be cleaned without dirt or detergent inside the weighing device can penetrate.
In einer zweckmäßigen Weiterbildung ist vorgesehen, dass die Waagschale eine umlaufende Nut aufweist, die mit einer Schulter des Abdichtmittels zusammenwirkt. Dadurch wird eine eindeutige Positionierung des Abdichtmittels auf der Waagschale erreicht. Zudem kann das Abdichtmittel von oben her abgenommen werden.In an appropriate training it is provided that the weighing pan has a circumferential groove, which cooperates with a shoulder of the sealant. Thereby is a clear positioning of the sealant on the pan reached. In addition, the sealing means can be removed from above.
Weitere zweckmäßige Weiterbildungen ergeben sich aus weiteren abhängigen Ansprüchen und aus der Beschreibung.Further appropriate training arise from other dependent Claims and from the description.
