Description

Die Erfindung bezieht sich auf eine Sortiereinrichtung, insbesondere für Bruchglas, mit einer sich in einem Winkel, vorzugsweise rechtwinkelig zu einem Strom des auszusortierenden Gutes erstreckenden optischen Detektoreinrichtung zur Erfassung von auszuscheidenden Teilen, welche Detektoreinrichtung eine Anzahl von in einer Reihe angeordneten, aufeinanderfolgend mit Impulsen ansteuerbaren Sender, z.B. Leuchtdioden, und diesen zugeordnete Empfänger aufweist, wobei jeder je einem Sender zugeordnete Empfänger lediglich während der Sendezeit des zugehörigen Senders aktivierbar ist.The invention relates to a sorting device, in particular for cullet, with an optical detector device which extends at an angle, preferably at right angles to a stream of the material to be sorted out, for detecting parts to be separated out, which detector device comprises a number of pulses which are arranged in a row and can be controlled sequentially Transmitter, e.g. Light-emitting diodes, and the receiver assigned to them, each receiver assigned to a transmitter being able to be activated only during the transmission time of the associated transmitter.

Derartige Sortiereinrichtungen weisen in der Regel nur sehr schmale Rutschen oder durch Zwischenwände in schmale Abschnitte unterteilte Rutschen auf, über die sich der Strom des auszusortierenden Gutes, z.B. Bruchglas, das mit Fremdkörpern, wie Metallteile oder Keramikteile vermengt ist, wobei der sich in einer relativ dünnen Schichte bewegende des Materialstromes mittels der Detektoren überwacht wird. Dabei werden alle Sender und die zugehörigen Empfänger beginnend von einem Ende der Detektoreinrichtung.Such sorting devices generally have only very narrow slides or slides divided into narrow sections by partition walls, via which the flow of the material to be sorted out, e.g. Broken glass, which is mixed with foreign bodies such as metal parts or ceramic parts, the material flow moving in a relatively thin layer being monitored by means of the detectors. All transmitters and the associated receivers start from one end of the detector device.

Der Nachteil dieser bekannten Lösungen besteht darin, daß sich größere Stücke in den schmalen Rutschen oder zwischen den Begrenzungswänden der einzelnen Rutschenabschnitte verklemmen können und es dadurch zu Störungen kommt. Eine Verbreiterung der Rutschen bzw. des Abstandes zwischen den die einzelnen Abschnitte derselben begrenzenden Trennwände ist kaum über eine Breite von ca. 10cm möglich, da andernfalls die Geschwindigkeit des auszusortierenden n Materialstromes erheblich reduziert werden müßte, um eine einwandfreie Erkennung von Fremdkörpern relevanter Größe gewährleisten zu können. Dies ist dadurch bedingt, daß die einzelnen Sender und Empfänger sehr nahe nebeneinander angeordnet werden müssen um auch kleinere Fremdkörper erkennen zu können. Dies führt aber dazu, daß die Abtastung einer bestimmten Breite der Rutsche eine entsprechende Zeit erfordert, da die einzelnen Impulse eine endliche Zeit dauern und und auch die Ansteuerung der einzelnen Sender und Empfänger eine entsprechende Zeit erfordern. Anderseits müssen die jeweils gleichen Sender innerhalb einer bestimmten Zeit wieder aktiviert werden, da sonst aufgrund der Vorschubgeschwindigkeit des zu überwachenden Materialstromes auch größere Fremdkörper nicht erfaßt werden können.The disadvantage of these known solutions is that larger pieces can get stuck in the narrow slides or between the boundary walls of the individual slide sections and this leads to malfunctions. A widening of the slides or the distance between the dividing walls delimiting the individual sections of the same is hardly possible over a width of approx. 10 cm, since otherwise the speed of the material flow to be sorted out would have to be reduced considerably in order to ensure correct detection of foreign bodies of relevant size can. This is due to the fact that the individual transmitters and receivers have to be arranged very close to one another in order to be able to recognize even small foreign bodies. However, this means that the scanning of a certain width of the slide requires a corresponding time, since the individual pulses last a finite time and the activation of the individual transmitters and receivers also require a corresponding time. On the other hand, the same transmitter must be reactivated within a certain time, because otherwise larger foreign objects cannot be detected due to the feed rate of the material flow to be monitored.

Um eine ausreichend hohe Fördergeschwindigkeit des auszusortierenden Materialstromes zu ermöglichen, wurden bisher die Rutschen zumeist in schmälere, durch Wände voneinander getrennte Abschnitte unterteilt, wodurch sich aber die oben erwähnten Probleme bei größeren Stücken im Merterialstrom ergeben.In order to enable a sufficiently high conveying speed of the material flow to be sorted out, the chutes have so far mostly been divided into narrower sections separated by walls, but this has resulted in the above-mentioned problems with larger pieces in the material flow.

Ziel der Erfindung ist es, diese Nachteile zu vermeiden und eine Sortiereinrichtung der eingangs erwähnten Art vorzuschlagen, bei der ein Aussortieren auch bei einem in einem breiten und eine hohe Vorschubgeschwindigkeit aufweisenden Strom einwandfrei möglich ist, ohne daß es dabei zu Fehlsortierungen kommt.The aim of the invention is to avoid these disadvantages and to propose a sorting device of the type mentioned at the outset, in which sorting out is perfectly possible even with a current having a wide and high feed rate, without resulting in incorrect sorting.

Erfindungsgemäß wird dies dadurch erreicht, daß mehrere voneinander vorzugsweise gleich beabstandete Sender gleichzeitig aktivierbar sind.This is achieved according to the invention in that a plurality of transmitters, which are preferably equally spaced from one another, can be activated simultaneously.

Auf diese Weise wird erreicht, daß ein breiter Materialstrom mit üblicher Vorschubgeschwindigkeit ausreichend überwacht werden kann, um Fremdkörper relevanter Größe erkenne zu können, da eben der Materialstrom mit einer entsprechend feinen Rasterung der von den Sendern ausgesandten Impulsen abgetastet wird.In this way it is achieved that a wide stream of material can be adequately monitored at the usual feed rate in order to be able to recognize foreign bodies of relevant size, since the stream of material is scanned with a correspondingly fine grid of the pulses emitted by the transmitters.

Dabei kann nach einem weiteren Merkmal der Erfindung vorgesehen sein, daß die Sender in nebeneinander liegenden Gruppen unterteilt sind und die Sender einer jeden Gruppe in einem sich wiederholenden Zyklus nacheinander einzeln ansteuerbar sind und die in der Reihenfolge der Ansteuerung gleichen Sender aller Gruppen parallel geschaltet oder parallel ansteuerbar sind.It can be provided according to a further feature of the invention that the transmitters are divided into adjacent groups and the transmitters of each group can be individually controlled in a repeating cycle and the transmitters of all groups that are the same in the sequence of activation are connected in parallel or in parallel are controllable.

Dadurch wird die Rutsche im Hinblick auf ihre Überwachung in relativ schmale Gruppen unterteilt, sodaß sich im Hinblick auf die Überwachung die gleichen Verhältnisse ergeben, wie bei den bekannten Lösungen mit den durch Zwischenwände unterteilten Rutschen, wobei aber auf die körperlichen Zwischenwände verzichtet werden kann und daher die Probleme mit größeren Teilen vermieden sind.As a result, the slide is subdivided into relatively narrow groups with regard to its monitoring, so that the same conditions result with regard to monitoring as with the known solutions with the slides divided by partition walls, but the physical partition walls can be dispensed with and therefore the problems with larger parts are avoided.

Dabei kann weiters vorgesehen sein, daß jeweils 10 Sender zu einer Gruppe zusammengefaßt sind, die ausgehend von einem Rand der Gruppe der Reihe nach fortlaufend ansteuerbar sind.It can further be provided that in each case 10 transmitters are combined to form a group, which can be controlled sequentially starting from one edge of the group.

Grundsätzlich ist aber auch möglich die Ansteuerung der Sender und Empfänger in der Weise vorzunehmen, daß die Sender beginnend von einem Ende der Senderanordnung der Reihe nach angesteuert werden, wobei gleichzeitig die in einem bestimmten Abstand von dem jeweils angesteuerten Sender angeordnet Sender ebenfalls angesteuert wird. Beispielsweise könnte dies in der Weise erfolgen daß die jeweils zehnten Sender gleichzeitig angesteuert werden.In principle, however, it is also possible to control the transmitters and receivers in such a way that the transmitters are controlled in sequence starting from one end of the transmitter arrangement, the transmitters arranged at a certain distance from the respectively controlled transmitter also being controlled at the same time. For example, this could be done in such a way that the tenth transmitters are controlled simultaneously.

Die Erfindung wird nun anhand der Zeichnung näher erläutert. Dabei zeigen:

  • Fig. 1 schematisch eine Sortiereinrichtung,
  • Fig. 2 schematisch die Anordnung der Sender der Sortiereinrichtung.
The invention will now be explained in more detail with reference to the drawing. Show:
  • 1 schematically shows a sorting device,
  • Fig. 2 shows schematically the arrangement of the transmitters of the sorting device.

Fig. 1 zeigt schematisch eine Sortiereinrichtung zum aussortieren von Fremdkörpern, wie Metallstücken, Keramik- oder Steingutstücken aus einem Bruchglasstrom. Bei dieser Einrichtung ist eine an die Aufgabestation 1 anschließende Rutsche 2 vorgesehen, in deren unterem Bereich ein aus Sendern 3 und Empfängern 4 bestehende Detektoreinrichtung zur Erfassung von Fremdkörpern im Bruchglasstrom angeordnet. diese Detektoreinrichtung steuert am Ende der Rutsche 2 angeordnete Düsen 5, die unterhalb des in diesem Bereich dem Verlauf einer Wurfparabel folgenden Bruchglasstrom angeordnet sind. und bei einer Aktivierung die Fremdkörper nach oben auslenken, sodaß diese in den Abfallbehälter 6 fallen und daher von dem in den Behälter 7 fallenden Bruchglas getrennt werden.Fig. 1 shows schematically a sorting device for sorting out foreign bodies, such as metal pieces, ceramic or stoneware pieces from a broken glass stream. In this device, a chute 2 adjoining the feed station 1 is provided, in the lower area of which a detector device consisting of transmitters 3 and receivers 4 is arranged for detecting foreign bodies in the broken glass stream. this detector device controls at the end of the slide 2 arranged nozzles 5, which below the in this area The course of a throwing parabola following crushed glass flow are arranged. and when activated, deflect the foreign bodies upward so that they fall into the waste container 6 and are therefore separated from the broken glass falling into the container 7.

Wie aus der Fig. 2 zu ersehen ist, sind die Sender 3 in Gruppen A, B, C, D, E zu je zehn Sendern, denen eine entsprechende Anzahl von Empfängern 4 gegenüberliegt, zusammengefaßt.As can be seen from FIG. 2, the transmitters 3 are combined in groups A, B, C, D, E to ten transmitters each, to which a corresponding number of receivers 4 lie.

Die Ansteuerung der einzelnen Sender 3 erfolgt in der Weise, daß beginnend mit dem ersten Sender einer Gruppe die übrigen Sender der Reihe nach aktiviert werden. Dabei sind die jeweils gleichnamigen Sender 3 einer jeden Gruppe A, B, C, D, E parallel geschaltet, sodaß z.B. die ersten Sender samt deren zugeordneten Empfängern einer jeden Gruppe stets gleichzeitig aktiviert werden.The control of the individual transmitters 3 is carried out in such a way that the other transmitters are activated in sequence starting with the first transmitter in a group. The transmitters 3 of the same name of each group A, B, C, D, E are connected in parallel, so that e.g. the first transmitters and their assigned receivers of each group are always activated simultaneously.

Nach Aktivierung des letzten Senders 3 einer jeden Gruppe wiederholt sich der Zyklus.After activating the last transmitter 3 of each group, the cycle repeats.
