Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum optischen Zählen kleiner Körperchen gemäß der Oberbegriffe der Patentansprüche 1 und 2.The The invention relates to a device for optically counting smaller corpuscles according to the generic terms of the claims 1 and 2.
Derartige Vorrichtungen zum optischen Zählen kleiner Körperchen sind in vielfältiger Weise bekannt. Diese Vorrichtungen werden beim Zählen von Saatkörnern, die von dem Vereinzelungsorgan einer Einzelkornsämaschine, insbesondere vereinzelt werden, eingesetzt. Derartige Körner werden vereinzelt und mit Abstand zueinander über Saatleitungen von den Vereinzelungsorganen zu Saatgutablegeeinrichtungen transportiert. Die bisherigen Vorrichtungen zum optischen Zählen kleiner Körperchen sind sehr aufwendig aufgebaut oder weisen eine einzelne Lichtschranke auf, um lediglich zu überwachen ob Saatkörner ausgebracht werden oder nicht. Diese bekannten Vorrichtungen zum optischen Zählen kleiner Körperchen können nicht über ein großes Breitenspektrum verschiedene Saatkörner, auch nicht vereinzelte Saatkörner zu zählen.such Devices for optical counting small body are in more diverse Way known. These devices are used in counting seeds which from the separating element of a precision seed drill, in particular isolated be used. Such grains are isolated and spaced from each other via seed lines of the separating organs transported to seed depositing devices. The previous devices for optical counting small body are very complex or have a single photocell to just monitor if seeds be applied or not. These known devices for optical counting small body can no over a big Broad spectrum of different seeds, not even sporadic rook to count.
Daher liegt der Erfindung die Aufgabe zugrunde, eine einfach aufgebaute Vorrichtung, die einfach an der Ausbringleitung anzuordnen ist, vorzuschlagen.Therefore The invention is based on the object, a simply constructed Device which is easy to arrange on the delivery line, propose.
Diese Aufgabe wird erfindungsgemäß in einer ersten Lösung dadurch gelöst, dass die Anzahl der jeweils von zumindest einem Sender- und Empfängerelement gebildeten Sensoren eine ungerade Zahl und größer als 2 ist. Infolge dieser Maßnahme ist es in einfacher Weise möglich, die Vorrichtung symmetrisch aufzubauen. Die einzelnen Elemente der Sensoren, die die Vorrichtung zum optischen Zählen der Körperchen sind, können somit gleichmäßig verteilt um den zu messenden und abzutastenden Bereich angeordnet werden, wobei die Sende- und Empfängerelemente bereits zumindest annähernd gegenüberliegend angeordnet werden können.These Object is according to the invention in a first solution solved by that the number of each of at least one transmitter and receiver element formed sensors is an odd number and greater than 2. As a result of this Measure is it in a simple way possible to build up the device symmetrically. The individual elements of the Sensors that are the device for optically counting the corpuscles can thus equally distributed be arranged around the area to be measured and scanned, wherein the transmitting and receiving elements already at least approximate opposite can be arranged.
Bei einer zweiten Lösung ist vorgesehen, dass die Sende- und oder Empfängerelemente auf der Außenseite der Leitung um diese kreisförmig verteilt angeordnet sind, und zumindest annähernd bis zu der Außenwand der Leitung reichen, dass zwischen den Sende- und Empfängerelement diese gegeneinander abschirmende Wandelemente angeordnet sind, dass die abschirmenden Wandelemente zumindest annähernd bis zu der Außenwand der Leitung reichen. Infolge dieser Maßnahmen werden die Sende- und Empfängerelemente kreisförmig um den abzutastenden Bereich der Leitung angeordnet. Durch die Wandelemente wird Streulicht oder Streuwellen der Senderelemente auf ein möglichst geringes Maß begrenzt.at a second solution it is envisaged that the transmitting and or receiving elements on the outside the line around this circular are distributed, and at least approximately to the outer wall The line that is between the transmitting and receiving element these mutually shielding wall elements are arranged that the shielding wall elements at least approximately to the outer wall the line. As a result of these measures, the transmission and receiver elements circular arranged around the area of the line to be scanned. Through the wall elements Stray light or stray waves of the transmitter elements to a possible Limited in size.
Um dieses Abschirmen in einfacher Weise möglichst optimal zu gestalten, ist vorgesehen, dass zumindest einige der abschirmenden Wandelemente bis an die Außenwand der Leitung heranreichen.Around to make this shielding as optimal as possible in a simple manner, is provided that at least some of the shielding wall elements up to the outside wall reach the line.
Eine besonders einfache Ausgestaltung der Sende- und Empfängerelemente der Sensoren lässt sich dadurch erreichen, dass die Leitung zumindest in dem Bereich, in denen der Sensor angeordnet ist, aus einem durchsichtigen Material besteht. Hierdurch wird ein Durchscheinen von Infrarotlicht durch die Leitungen in einfacher Weise ermöglicht.A particularly simple embodiment of the transmitting and receiving elements the sensors can be thereby achieve that the line at least in the area in which the sensor is arranged, made of a transparent material consists. As a result, a transmission of infrared light through the Lines in a simple manner allows.
Eine vorteilhafte Anordnung der Sensoren der Vorrichtung zum optischen Zählen kleiner Körperchen lässt sich in einfacher Weise dadurch erreichen, dass die Sensoren gleichmäßig verteilt angeordnet sind.A advantageous arrangement of the sensors of the device for optical counting small body let yourself in a simple way achieve that the sensors evenly distributed are arranged.
