Description

Die Erfindung betrifft ein Verfahren zum Sortieren von Altpapier unterschiedlicher Qualität und Beschaffenheit, bei dem zumindest ein Bereich der Oberfläche verschiedener Altpapierfraktionen, wie Papier und Karton, die beispielsweise auf mindestens einem Sortierband liegen, bestrahlt wird und die von den Altpapierstücken der einzelnen Fraktionen reflektierte Strahlung erfasst und die Altpapierstücke aufgrund der ermittelten Daten einer bestimmten Altpapierfraktion zugeordnet und anschließend entsprechend sortiert werden, sowie eine entsprechende Vorrichtung.The invention relates to a method for sorting waste paper of different quality and constitution in which at least a portion of the surface is different Waste paper fractions, such as paper and cardboard, for example, on at least one Sorting tape lie, is irradiated and that of the waste paper pieces of the individual fractions reflected radiation detected and the waste paper pieces due to the determined Data associated with a specific waste paper fraction and then accordingly be sorted, as well as a corresponding device.

Ein gattungsgemäßes Verfahren und eine gattungsgemäße Vorrichtung sind aus der Gebrauchsmusterschrift AT 001 959 U1, Anmeldenummer GM 246/97, bekannt. Die Fraktionen werden laut AT 001 959 U1 auf einem Sortierband getrennt, indem diese durch Strahlungsquellen (vorzugsweise Lichtquellen) bestrahlt werden und die reflektierten Strahlen von Auswerteeinheiten erfasst und die einer bestimmten Fraktion zugeordneten Altpapierstücke von Aufnehmern aufgenommen und auf einen vorbestimmten Ablageplatz gelegt werden.A generic method and a generic device are from the Utility Model AT 001 959 U1, application number GM 246/97, known. The fractions are separated according to AT 001 959 U1 on a sorting belt by this by Radiation sources (preferably light sources) are irradiated and the reflected Detected by evaluation units and assigned to a specific fraction Waste paper pieces picked up by transducers and placed in a predetermined storage space be placed.

Bei diesem Verfahren wird die reflektierte Strahlung mit einer Kamera aufgenommen und die spezifischen Merkmale - die unterschiedlichen Wellenlängen der reflektierten Strahlung - des aufgenommenen Bereichs mit gespeicherten, anlembaren Klassifikatoren verglichen. Mit dieser Bewertung kann oft die Zugehörigkeit der betrachteten Altpapierstükke zu einer der zu trennenden Fraktionen nicht eindeutig festgestellt werden, was zu einer unzureichenden Sortierung führt.In this method, the reflected radiation is recorded with a camera and the specific features - the different wavelengths of the reflected radiation - Of the recorded area compared with stored, settable classifiers. With this evaluation, the affiliation of the waste paper pieces considered can often be to one of the fractions to be separated can not be clearly established what to an insufficient sorting leads.

Die Aufgabe der vorliegenden Erfindung besteht nun darin, die Fehler bei der Sortierung zu verringern und ein rasches, einfaches Verfahren sowie eine entsprechende Vorrichtung zur Sortierung von Altpapier zu schaffen.The object of the present invention is now the errors in sorting and a quick, simple process and device to sort waste paper.

Die Erfindung ist dadurch gekennzeichnet, dass die Intensitätsunterschiede der Strahlung, die von benachbarten Teilflächen der betrachteten Fläche reflektiert werden, ermittelt werden.The invention is characterized in that the intensity differences of the radiation, which are reflected from adjacent sub-areas of the considered area determined become.

Neu an dieser Erfindung ist, dass durch die Heranziehung der jeder Altpapierfraktion eigenen Intensitätsverteilung eine bessere Zuordnung zu einer bestimmten Fraktion erzielt werden kann.What is new about this invention is that by using each recovered paper fraction own intensity distribution achieved a better allocation to a specific fraction can be.

Eine Ausgestaltung der Erfindung besteht darin, dass jeder der gleich großen Teilflächen ein Intensitätswert zugeordnet wird, der relative Unterschied zwischen den Intensitätswerten benachbarter Teilflächen bestimmt wird und für die betrachtete Fläche die Summe dieser Intensitätsunterschiede gebildet wird. Beispielsweise kann ein schmaler rechteckiger Streifen abgebildet werden, der in gleich große Rechtecke, die auch als Bildpunkte bezeichnet werden, unterteilt wird. Jedem Bildpunkt wird eine bestimmter Intensitätswert zugeordnet. Anschließend wird für jedes aus benachbarten Bildpunkten bestehende Bildpunkt-Paar die Differenz der Intensitätswerte gebildet und in der Folge werden alle Differenzen aufsummiert.An embodiment of the invention is that each of the same size faces an intensity value is assigned, the relative difference between the intensity values adjacent subareas is determined and for the considered area the sum this intensity differences is formed. For example, a narrow rectangular Strips are imaged in equally sized rectangles, also called picture elements be subdivided. Each pixel becomes a certain intensity value assigned. Subsequently, for each of adjacent pixels existing Pixel pair formed the difference of the intensity values and in the sequence all differences are summed up.

Dabei ist vorgesehen, dass die Altpapierstücke der Papierfraktion zugeordnet werden, wenn die Summe der Intensitätsunterschiede einen Grenzwert überschreitet. Denn wenn für die betrachtete Fläche hohe Intensitätsunterschiede zwischen den Bildpunkten auftreten, also beispielsweise oftmals ein Hell-Dunkel-Wechsel auftritt, kann davon ausgegangen werden, dass es sich um ein eng bedrucktes Altpapierstück und damit um Papier handelt. Die Summe der Intensitätsunterschiede ist daher entsprechend groß, der Grenzwert ist einstellbar und wird über Versuche bestimmt.It is provided that the waste paper pieces are assigned to the paper fraction, when the sum of the intensity differences exceeds a limit. Because if high intensity differences between the pixels occur for the considered area, So, for example, often a light-dark change occurs, it can be assumed be, that it is a closely printed waste paper piece and thus paper is. The sum of the intensity differences is therefore correspondingly large, the Limit value is adjustable and is determined by tests.

Analog ist vorgesehen, dass die Altpapierstücke der Kartonfraktion zugeordnet werden, wenn die Summe der Intensitätsunterschiede einen Grenzwert unterschreitet oder erreicht, da Karton im Allgemeinen kaum mit kleiner Schrift bedruckt ist und daher für die betrachtete Fläche keine oder nur geringe Intensitätsunterschiede zwischen benachbarten Bildpunkten auftreten. Der Grenzwert ist einstellbar und wird über Versuche bestimmt.Analogously, it is provided that the waste paper pieces are assigned to the cardboard fraction, if the sum of the intensity differences falls below or reaches a threshold, Since cardboard is generally hardly printed with small font and therefore for the considered surface no or only small intensity differences between adjacent Pixels occur. The limit can be set and is determined via experiments.

Für die Trennung von zwei Fraktionen - Papier und Karton - fallen die beiden genannten Grenzwerte zusammen.For the separation of two fractions - paper and cardboard - fall the two mentioned Limits together.

Vorteilhafterweise wird die Fläche erfindungsgemäß mit sichtbarem Licht bestrahlt. Dies erlaubt den Einsatz von standardmäßig verfügbaren und kostengünstigen Strahlungsquellen und Auswertevorrichtungen.Advantageously, the surface is irradiated according to the invention with visible light. This allows the use of standard available and cost-effective radiation sources and evaluation devices.

Eine weitere Ausgestaltung des Verfahrens sieht vor, dass zusätzlich ein Verfahren zum Sortieren verwendet wird, bei dem die Wellenlänge der reflektierten Strahlung berücksichtigt wird. Durch eine Kombination des erfindungsgemäßen Verfahrens mit dem in der AT 001 959 U1 gezeigten Verfahren kann die Genauigkeit der Sortierung noch weiter erhöht werden.A further embodiment of the method provides that additionally a method for Sorting is used, taking into account the wavelength of the reflected radiation becomes. By a combination of the method according to the invention with in the AT 001 959 U1 shown method can further accuracy of sorting increase.

Dabei wird beispielsweise so verfahren, dass zuerst mit dem Verfahren, bei dem die Wellenlänge der reflektierten Strahlung ermittelt wird, eine Zuordnung des Altpapierstücks zu einer bestimmten Fraktion versucht wird und im Fall, dass ein Altpapierstück einer bestimmten Fraktion nicht eindeutig zugeordnet werden kann, anschließend das Verfahren zum Sortieren, bei dem die Intensitätsunterschiede der reflektierten Strahlung ermittelt werden, angewendet wird. Damit können die Vorteile beider Verfahren kombiniert werden. Insbesondere können damit Altpapierstücke, die nach dem Verfahren gemäß AT 001 959 U1 sowohl Papier als auch Karton sein könnten (wie beispielsweise bestimmtes Zeitungspapier, dessen Farbe der von Karton ähnlich ist), eindeutig zugeordnet werden.In this case, for example, proceeding so first with the method in which the Wavelength of the reflected radiation is determined, an assignment of the waste paper piece to a certain fraction is tried and in the case of a waste paper piece can not be clearly assigned to a particular group, then the Method for sorting, in which the intensity differences of the reflected radiation to be determined. This combines the advantages of both methods become. In particular, waste paper pieces which are produced according to the method according to FIG AT 001 959 U1 could be both paper and cardboard (such as certain newsprint whose color is similar to that of cardboard) become.

Die Vorrichtung zur Durchführung eines Verfahrens zum Sortieren von Altpapier unterschiedlicher Qualität und Beschaffenheit, bei dem verschiedene Altpapierfraktionen, wie Papier und Karton, auf mindestens einem Sortierband zur Beförderung der Altpapierstücke liegen und über dem Sortierband zumindest eine Strahlungsquelle zur Bestrahlung von zumindest einem Bereich des Sortierbandes sowie zumindest eine Auswertevorrichtung, welche die von den Altpapierstücken der einzelnen Fraktionen reflektierte Strahlung erfasst und die Altpapierstücke aufgrund der ermittelten Daten einer bestimmten Altpapierfraktion zuordnet, angeordnet sind, wobei der Strahlungsquelle bzw. der Auswertevorrichtung in Förderrichtung des Sortierbandes zumindest eine Sortiereinrichtung nachgeordnet ist, ist dadurch gekennzeichnet, dass über dem Sortierband mindestens ein Teil einer Auswertevorrichtung angeordnet ist, die Intensitätsunterschiede der Strahlung, die von benachbarten Teilflächen der betrachteten Fläche reflektiert werden, ermittelt.The device for carrying out a method for sorting waste paper different Quality and texture, in which various waste paper fractions, such as Paper and cardboard, on at least one sorting belt for transporting waste paper pieces lie and above the sorting belt at least one radiation source for irradiation at least one region of the sorting belt and at least one evaluation device, which reflected the pieces of waste paper from the individual factions Radiation detected and the waste paper pieces due to the determined data of a certain Assigns waste paper fraction, are arranged, wherein the radiation source or the evaluation device in the conveying direction of the sorting belt at least one sorting device is subordinate, is characterized in that above the sorting belt at least a part of an evaluation device is arranged, the intensity differences the radiation that is reflected by adjacent partial areas of the considered area, determined.

Besonders einfach und kostengünstig lässt sich die Erfindung verwirklichen, wenn die Strahlungsquelle sichtbares Licht ausstrahlt.Particularly simple and inexpensive, the invention can be realized when the Radiation source emits visible light.

Dabei kann vorgesehen werden, dass die Auswertevorrichtung eine Kamera aufweist.It can be provided that the evaluation device has a camera.

Das erfindungsgemäße Verfahren lässt sich rasch und mit wenig Aufwand an Datenverarbeitung ausführen, wenn die Auswertevorrichtung eine Zeilenkamera aufweist. Diese tastet jeweils nur einen schmalen Streifen des interessierenden Bereichs ab, sodass nur für eine Reihe von Teilflächen die Intensitätsunterschiede bestimmt werden müssen.The inventive method can be quickly and with little effort to data processing execute when the evaluation device has a line scan camera. These scans only a narrow strip of the area of interest, so only for a number of faces the intensity differences must be determined.

Wenn eine Sortiereinrichtung zumindest eine Einrichtung zur Erzeugung einer Luftströmung beinhaltet, kann ohne mechanische Aufnahmevorrichtungen und damit verschleißfrei eine Altpapierfraktion aussortiert werden.If a sorter at least one means for generating an air flow includes, can without mechanical pick-up devices and thus wear-free a waste paper fraction are sorted out.

Dies geschieht beispielsweise dadurch, dass diese Einrichtungen als Blaseinrichtungen, wie Druckdüsen, insbesondere Druckluftdüsen, und/oder als Saugeinrichtungen, wie Unterdruckdüsen, Ventilatoren oder Pumpen, ausgebildet sind. Damit können die durch die Auswerteeinrichtung als Karton identifizierten Altpapierstücke beispielsweise am Ende des Sortierbandes gezielt durch Druckluft und/oder durch Unterdruck angehoben und über die Oberkante einer in Bewegungsrichtung des Sortierbandes gesehen nach dem Sortierband angeordneten Abscheidekante befördert werden, hinter der sie nach unten absinken. Die restlichen Fraktionen, beispielsweise die Papierfraktion, fallen durch die Umlenkung des Sortierbandes direkt nach diesem nach unten.This happens, for example, in that these devices are used as blowing devices, as pressure nozzles, in particular compressed air nozzles, and / or as suction devices, such as Vacuum nozzles, fans or pumps are formed. This can be through the evaluation as cardboard identified waste paper pieces, for example targeted at the end of the sorting belt lifted by compressed air and / or by negative pressure and seen over the top of a in the direction of movement of the sorting belt behind the sorting belt arranged Abscheidekante be conveyed, behind which they fall down. The remaining fractions, for example the paper fraction, fall by the deflection of the sorting belt directly after this down.

Zusätzlich zu oder statt einer Sortiereinrichtung mit Blaseinrichtungen und/oder Saugeinrichtungen - etwa wenn mehr als zwei Fraktionen zu trennen sind - kann vorgesehen werden, dass zumindest eine Sortiereinrichtung mit einer oder mehreren Aufnahmevorrichtungen, wie mechanischen Greifzangen, Saugern, Klemmwalzen, Nadelgreifern oder elektrostatischen Aufnahmevorrichtungen, ausgestattet ist. Für die genaue Ausführung und Anordnung der Sortiereinrichtungen wird auf die AT 001 959 U1 verwiesen.In addition to or instead of a sorting device with blowing devices and / or suction devices - For example, if more than two fractions are to be separated - can be provided be that at least one sorting device with one or more receiving devices, such as mechanical tongs, suckers, pinch rollers, needle grippers or electrostatic recording devices, is equipped. For the exact execution and arrangement of the sorting devices, reference is made to AT 001 959 U1.

Weiters ist es von Vorteil, wenn die Strahlungsquelle selbst Strahlung in zumindest einem Teilbereich des Frequenzbereichs von Infrarot bis Röntgenstrahlung aussendet und die Auswertevorrichtung auch die Wellenlänge der reflektierten Strahlung auswertet. Damit kann auf einfache Weise eine Kombination von zwei Sortierverfahren, nämlich einem Verfahren, bei dem die Wellenlänge der reflektierten Strahlung ermittelt wird, und dem erfindungsgemäßen Verfahren zum Sortieren, bei dem die Intensitätsunterschiede der reflektierten Strahlung ermittelt werden, erreicht werden.Furthermore, it is advantageous if the radiation source itself radiation in at least one Part of the frequency range from infrared to X-rays and emits the evaluation device also evaluates the wavelength of the reflected radiation. This can easily be a combination of two sorting, namely a method in which the wavelength of the reflected radiation is determined, and the method according to the invention for sorting, in which the intensity differences the reflected radiation are determined to be achieved.

Alternativ kann vorgesehen werden, dass zumindest eine weitere Strahlungsquelle, die Strahlung in zumindest einem Teilbereich des Frequenzbereichs von Infrarot bis Röntgenstrahlung aussendet, und zumindest eine zusätzliche Auswertevorrichtungen, die die Wellenlänge der reflektierten Strahlung auswertet, angeordnet sind. Es können somit auch für jedes der beiden Sortierverfahren jeweils zumindest eine eigene Strahlungsquelle und Auswertevorrichtung vorgesehen werden. Dies wird dann nötig sein, wenn sich die für das jeweilige Verfahren benötigten Wellenlängen der Strahlung zu stark voneinander unterscheiden.Alternatively it can be provided that at least one further radiation source, the Radiation in at least a portion of the frequency range from infrared to X-radiation emits, and at least one additional evaluation, the Wavelength of the reflected radiation evaluates are arranged. It can thus also for each of the two sorting in each case at least one own radiation source and evaluation are provided. This will be necessary if the wavelengths of the radiation required for the respective process are too strong from each other differ.

Die Erfindung wird anhand der Figur, die beispielhaft und schematisch eine Seitenansicht einer erfindungsgemäßen Vorrichtung zeigt, näher erläutert.The invention is based on the figure, the example and schematically a side view a device according to the invention shows, explained in more detail.

Auf einem Sortierband 1, welches in Förderrichtung 2 bewegbar ist, sind die Altpapierfraktionen 7 aufgelegt. Das Sortierband 1 ist in mehrere Spuren unterteilt. Über dem Sortierband 1 ist ein Modul angeordnet, das wenigstens eine Lichtquelle 3 mit zugehörigem Reflektor 4 und eine Kamera 5 enthält. Die Kamera 5 ist als Zeilenkamera ausgebildet und bildet einen Streifen ab, dessen Länge in etwa der Breite des Sortierbandes 1 entspricht und somit alle Spuren abdeckt und dessen Breite, (nicht maßstäblich) dargestellt durch den Abbildungsbereich 6, in der Größenordnung von einigen Millimetern liegt. In der Kamera 5 ist eine Prozessoreinheit angeordnet, welche die Daten auswertet und die zugeordnete Sortiereinrichtung steuert.On a sorting belt 1, which is movable in the conveying direction 2, the recovered paper fractions 7 launched. The sorting belt 1 is divided into a plurality of tracks. Above that Sorting belt 1 is a module arranged, the at least one light source 3 with associated Reflector 4 and a camera 5 contains. The camera 5 is designed as a line camera and forms a strip whose length is approximately equal to the width of the sorting belt 1 corresponds and thus covers all traces and its width, (not to scale) shown through the imaging region 6, on the order of a few millimeters. In the camera 5, a processor unit is arranged, which evaluates the data and controls the associated sorting device.

Über dem Sortierband 1 können jedoch auch - in Zeichenebene gesehen hintereinander - mehrere Module angeordnet sein, die jeweils mehrere Lichtquellen 3 mit zugehörigem Reflektor 4 und eine Kamera 5 enthalten. Für jede Spur ist ein Modul vorgesehen. Diese Module bilden eine Gruppe von Modulen. Die Kameras 5 bilden dann jeweils einen Streifen ab, der in etwa der Breite einer Spur entspricht. Jede Kamera 5 enthält entweder selbst eine Prozessoreinheit oder alle Kameras 5 sind mit einer zentralen Prozessoreinheit verbunden, mit der sie gemeinsam die Auswertevorrichtung bilden.But above the sorting belt 1 can also - as seen in the drawing plane one after the other - Be arranged several modules, each having a plurality of light sources 3 with associated Reflector 4 and a camera 5 included. For each track a module is provided. These Modules form a group of modules. The cameras 5 then each one Strip off, which corresponds approximately to the width of a track. Each camera 5 contains either even a processor unit or all cameras 5 are provided with a central processing unit connected, with which they together form the evaluation device.

Die Altpapierfraktionen 7 werden unter der Kamera 5 mit Licht aus den Lichtquellen 3 bestrahlt, wobei das reflektierte Licht gemäß dem Abbildungsbereich 6 von der Kamera 5 aufgenommen wird. Die Kamera 5 ist als Zeilenkamera ausgebildet und liefert eine Abbildung, die aus einer Reihe Bildpunkte besteht, wobei jeder Bildpunkt eine bestimmte Helligkeit bzw. Intensität, z.B. einen bestimmten Grauwert, aufweist. Die Bilddaten werden zur weiteren Auswertung sowie zur genauen Lagebestimmung des Altpapierstücks an die in der Kamera befindliche Prozessoreinheit oder an die zentrale Prozessoreinheit weitergeleitet. Dort wird für jedes Bildpunkt-Paar die Differenz der Intensitätswerte gebildet und die Summe aller Differenzen einer Abbildung gebildet und eine entsprechende Zuordnung zur Papier- oder Kartonfraktion vorgenommen.The waste paper fractions 7 are under the camera 5 with light from the light sources. 3 irradiated, wherein the reflected light according to the imaging area 6 of the camera. 5 is recorded. The camera 5 is designed as a line scan camera and provides an image which consists of a series of pixels, each pixel being a specific one Brightness or intensity, e.g. a certain gray value. The image data will be for further evaluation as well as for the exact orientation of the waste paper piece to the processor unit located in the camera or to the central processor unit forwarded. There, the difference of the intensity values is formed for each pixel pair and the sum of all differences of an image formed and a corresponding one Assigned to the paper or cardboard fraction.

Die in der jeweiligen Kamera befindliche bzw. die zentrale Prozessoreinheit speichert die Lage der einer bestimmten Fraktion zugeordneten Altpapierstücke und steuert entsprechend die Sortiereinrichtung. Diese besteht hier im Wesentlichen aus Druckdüsen 10, wie beispielsweise Druckluftdüsen, die am Ende des Sortierbandes 1 in einem spitzen Winkel zur Ebene des Sortierbandes 1 unterhalb desselben angeordnet sind. Pro Spur des Sortierbandes 1 ist mindestens eine Druckdüse 10 vorgesehen. Zusätzlich oder statt der Druckdüsen 10 kann in etwa gegenüberliegender Position mindestens eine Unterdruckdüse 14 angeordnet werden, die Luft ansaugt und somit die Hubwirkung der Druckdüse 10 verstärkt. Statt Unterdruckdüsen 14 können auch andere Saugeinrichtungen, wie Ventilatoren oder Unterdruckpumpen, eingesetzt werden.The respectively located in the respective camera or the central processing unit stores the Location of the waste paper pieces assigned to a specific fraction and controls accordingly the sorting device. This consists essentially of pressure nozzles 10, such as compressed air nozzles that point at the end of the sorting belt 1 in a Angle to the level of the sorting belt 1 are arranged below it. Per track of the sorting belt 1, at least one pressure nozzle 10 is provided. In addition or instead The pressure nozzles 10 may be in approximately opposite position at least one vacuum nozzle 14 are arranged, the air sucks and thus the lifting effect of Pressure nozzle 10 reinforced. Instead of vacuum nozzles 14, other suction devices, like fans or vacuum pumps.

Erreicht ein als Papier identifiziertes Altpapierstück 8 das Ende des Sortierbandes 1, so erfolgt durch die Druckdüsen 10 keine Luftzufuhr bzw. durch die Unterdruckdüsen 14 keine Sogwirkung und das Papierstück 8 sinkt im Anschluss an das Sortierband 1 nach unten in einen als Papierbehälter 11 ausgeführten Ablageplatz.If a paper piece 8 identified as paper reaches the end of the sorting belt 1, then No air supply or through the vacuum nozzles 14 takes place through the pressure nozzles 10 no suction effect and the piece of paper 8 sinks after the sorting belt 1 below in a designed as a paper tray 11 storage space.

Erreicht ein als Karton identifiziertes Altpapierstück 9 das Ende des Sortierbandes 1, so wird durch die Druckdüsen 10 und/oder durch die Unterdruckdüsen 14, die alle von der (zentralen) Prozessoreinheit - gegebenenfalls für die einzelnen Spuren getrennt - gesteuert werden, Druckluft zugeführt bzw. Unterdruck erzeugt und das Kartonstück 9 kann aufgrund der ausgeübten Kraft nicht sofort absinken, sondern wird in Förderrichtung 2 des Sortierbands 1 weitergetragen, über die Abscheidekante 13 des als Kartonbehälter 12 ausgeführten Ablageplatzes hinweg, und sinkt schließlich auf den Ablageplatz. Dieser kann jedoch sowohl für Papier als auch für Karton beispielsweise auch als Förderband ausgebildet sein.If a paper piece 9 identified as cardboard reaches the end of the sorting belt 1, then is through the pressure nozzles 10 and / or by the vacuum nozzles 14, all of the (central) processor unit - possibly separated for the individual tracks - be controlled, supplied compressed air or negative pressure generated and the cardboard piece. 9 can not fall immediately due to the applied force, but is in the conveying direction 2 of the sorting belt 1 carried over the Abscheidekante 13 of the cardboard container 12 running out of storage space, and finally sinks to the storage space. This can, however, both for paper and for cardboard, for example, as Be formed conveyor belt.

Eine andere Möglichkeit der Trennung von Papier und Karton besteht darin, dass die Positionen von Kartonbehälter 12 und Papierbehälter 11 sowie die Positionen von Druckdüsen 10 und Unterdruckdüsen 14 vertauscht werden, wobei hier ebenfalls entweder nur Druckdüsen 10 oder nur Unterdruckdüsen 14 (oder andere Saugeinrichtungen) oder beide Arten von Einrichtungen angeordnet werden.Another way to separate paper and cardboard is to use the Positions of cardboard container 12 and paper container 11 and the positions of Pressure nozzles 10 and vacuum nozzles 14 are reversed, here also either only pressure nozzles 10 or only vacuum nozzles 14 (or other suction devices) or both types of devices are arranged.

Erreicht ein als Papier identifiziertes Altpapierstück 8 das Ende des Sortierbandes 1, so erfolgt durch die Druckdüsen 10 keine Luftzufuhr bzw. durch die Unterdruckdüsen 14 keine Sogwirkung und das Papierstück 8 sinkt im Wesentlichen der Wurfparabel folgend nach unten in den Papierbehälter 11, der nun in Förderrichtung 2 des Sortierbandes 1 gesehen nach dem Kartonbehälter angeordnet ist.If a paper piece 8 identified as paper reaches the end of the sorting belt 1, then No air supply or through the vacuum nozzles 14 takes place through the pressure nozzles 10 no suction effect and the piece of paper 8 decreases substantially following the parabola down into the paper container 11, now in the conveying direction 2 of the sorting belt. 1 seen after the cardboard container is arranged.

Erreicht ein als Karton identifiziertes Altpapierstück 9 das Ende des Sortierbandes 1, so wird durch die Druckdüsen 10 von oben Druckluft zugeführt und/oder durch die Unterdruckdüsen 14 ein Unterdruck erzeugt und das Kartonstück 9 wird aufgrund der ausgeübten Kraft sofort nach unten bewegt und im Kartonbehälter 12, der sich direkt an das Sortierband 1 anschließt, gesammelt.If a paper piece 9 identified as cardboard reaches the end of the sorting belt 1, then Compressed air is supplied from above through the pressure nozzles 10 and / or through the vacuum nozzles 14 creates a negative pressure and the cardboard piece 9 is due to the exerted Force immediately moved down and in the cardboard box 12, which is directly attached to the Sorting belt 1 connects, collected.

Hier sei angemerkt, dass selbstverständlich sowohl nur Ansaugen als auch nur Ausblasen als auch eine Kombination davon möglich ist. Und zwar jeweils sowohl allein für eine Fraktion, wie hier für Karton beschrieben, jedoch auch allein für Papier. Zweckmäßigerweise wird die Ausblasung/Ansaugung für die Fraktion mit geringerem Anteil erfolgen. Die Ablageplätze sind dann entsprechend anzuordnen. Natürlich können auch beide Fraktionen angesaugt und/oder ausgeblasen werden. It should be noted that, of course, both only aspiration and only purging as well as a combination of it is possible. And in each case alone for one Fraction, as described here for cardboard, but also for paper alone. Conveniently, the purging / aspiration will be done for the lower fraction fraction. The storage spaces must then be arranged accordingly. Of course, both can Aspirated and / or blown out fractions.

Das Sortierband 1 wird vorzugsweise kontinuierlich weiterbewegt, sodass die Bewegung für die Abtrennung der Kartonstücke 9 bzw. der Papierstücke 8 genützt werden kann. Weitere Ausführungsformen der Erfindung ergeben sich durch Kombination mit der in der AT 001 959 U1 gezeigten Vorrichtung bzw. dem darin gezeigten Verfahren.The sorting belt 1 is preferably moved continuously, so that the movement for the separation of the cardboard pieces 9 and the paper pieces 8 can be used. Further embodiments of the invention result from combination with the in the AT 001 959 U1 shown device or the method shown therein.

So können über dem Sortierband 1 - in Bewegungsrichtung des Sortierbandes gesehen - vor der erfindungsgemäßen Gruppe von Modulen, die jeweils mehrere Lichtquellen 3 mit zugehörigem Reflektor 4 und eine Kamera 5 umfassen, eine weitere Gruppe von Modulen angeordnet werden, wobei ein Modul jeweils mehrere Strahlungsquellen und eine Kamera besitzt, welche die unterschiedlichen Wellenlängen der reflektierten Strahlung erfasst. Auf diese Weise kann zuerst eine Zuordnung der Altpapierstücke anhand der Wellenlängen der reflektierten Strahlung erfolgen und anschließend eine Zuordnung anhand der Intensitätsunterschiede der reflektierten Strahlung. Dies ist insbesondere dann vorteilhaft, wenn die Zuordnung nach dem ersten Verfahren oft nicht eindeutig ist.So can be seen above the sorting belt 1 - in the direction of movement of the sorting belt - In front of the group of modules according to the invention, each having a plurality of light sources. 3 with associated reflector 4 and a camera 5, another group of Modules are arranged, wherein a module in each case a plurality of radiation sources and has a camera, which the different wavelengths of the reflected radiation detected. In this way, first, an assignment of the waste paper pieces based the wavelengths of the reflected radiation and then an assignment based on the intensity differences of the reflected radiation. This is special then advantageous if the assignment is often ambiguous after the first method.

Wenn beide Verfahren mit Strahlung gleicher Wellenlänge arbeiten, können beide Verfahren mit einer Gruppe von Modulen ausgeführt werden, wobei ein Modul beispielsweise für jedes Verfahren eine Kamera oder eine Kamera für beide Verfahren, und für beide Verfahren die gleichen Strahlungsquellen aufweist.If both methods work with radiation of the same wavelength, both methods with a group of modules, for example, one module for each procedure a camera or a camera for both procedures, and for both Method has the same radiation sources.

Wenn mehr als zwei Fraktionen getrennt werden sollen, so können mehrere Gruppen von Modulen, die eine Zuordnung anhand der Wellenlängen der reflektierten Strahlung vornehmen, in Förderrichtung des Sortierbandes hintereinander angeordnet werden. Gegebenenfalls ist direkt nach jeder Gruppe von Modulen eine Sortiereinrichtung vorgesehen, die zumindest eine Fraktion aussortiert. Diese Sortiereinrichtung kann verschiedene Aufnahmevorrichtungen, wie Sauger (gegebenenfalls in Kombination mit einem Klemmwalzenpaar), Greifzangen, Nadelgreifer oder elektrostatische Aufnahmevorrichtungen aufweisen, wobei die aussortierte Fraktion durch die Aufnahmevorrichtungen auf einen vorbestimmten Ablageplatz oder ein weiteres Förderband verbracht wird.If more than two fractions are to be separated, then several groups can be used of modules that assign by the wavelengths of the reflected radiation make, in the conveying direction of the sorting belt are arranged one behind the other. Optionally, a sorting device is provided immediately after each group of modules, the at least one fraction sorted out. This sorting device can be various Receiving devices, such as suckers (optionally in combination with a Pinch roller pair), tongs, needle grippers or electrostatic pickup devices having the sorted fraction through the receiving devices on a predetermined storage space or another conveyor belt is spent.

Die Kartonfraktion kann entweder ebenfalls mit Hilfe der genannten mechanischen Sortiereinrichtung oder mit einer Sortiereinrichtung, die Einrichtungen zur Erzeugung einer Luftströmung beinhalten, aussortiert werden.The cardboard fraction can either also with the help of said mechanical sorter or with a sorting device, the means for generating a Contain air flow, be sorted out.

Jede Kamera 5 eines Moduls weist entweder selbst eine Prozessoreinheit auf oder ist mit einer zentralen Prozessoreinheit verbunden. Im letzteren Fall weisen die Module einer Gruppe eine gemeinsame zentrale Prozessoreinheit auf, auch mehrere Gruppen von Modulen können - gegebenenfalls eine weitere - gemeinsame zentrale Prozessoreinheit besitzen. Diese aktiviert aufgrund der ermittelten Daten zum gegebenen Zeitpunkt die entsprechenden Aufnahmevorrichtung bzw. die Druckluftdüsen der einzelnen Sortiereinrichtungen.Each camera 5 of a module either has its own processor unit or is connected to a central processor unit. In the latter case, the modules have a Group a common central processing unit, even several groups of Modules can - possibly another - common central processing unit have. This activates the data at the given time on the basis of the determined data corresponding receiving device or the compressed air nozzles of the individual sorting devices.

Mit der Erfindung wird ein weiteres Kriterium zur Verfügung gestellt, um Altpapier, insbesondere Karton und Papier, zu trennen, wenn eine Trennung mit Hilfe der herkömmlichen Verfahren nur unzureichend möglich ist, was einen wesentlichen Fortschritt bei der Klassifizierung von Altpapierstücken darstellt. Die folgende optionale Sortierung nur mit Hilfe von Einrichtungen, die Luftströmungen erzeugen, ermöglicht eine genaue, rasche und verschleißfreie Umsetzung dieser Klassifizierung.With the invention, a further criterion is provided to waste paper, in particular Cardboard and paper, to separate, if a separation with the help of conventional Process is insufficiently possible, which is a significant advance in the Classification of waste paper pieces represents. The following optional sorting only with Help of devices that generate air currents, allows an accurate, rapid and wear-free implementation of this classification.
