Description

Die Erfindung bezieht sich auf einen Vorrichtung der im Oberbegriff des Patentanspruchs 1 angegebenen Art.The invention relates to a device of the type specified in the preamble of claim 1.

Beim Druck von Wertscheinen, insbesondere Banknoten, Aktien oder ähnlichen Dokumenten, werden im allgemeinen grössere Bogen mit einer Vielzahl von Einzelstücken gedruckt. Diese Bogen werden dann visuell geprüft, um Druckfehler zu ermitteln, wobei der Prüfer die Fehldrucke, die auszusondern sind, mit einer fluoreszierenden Farbe markiert. Die Bogen werden dann in Einzelstücke zerschnitten und die Einzelstücke an einem auf die Markierungen ansprechenden Detektor vorbeigeführt. Die Einzelstücke gelangen in eine von diesem Detektor gesteuerte Sortiervorrichtung, in welcher die markierten Fehldrucke automatisch ausgesondert werden, während die einwandfreien Einzelstücke zur Weiterverarbeitung, beispielsweise zum Aufbringen eines Nummernaufdruckes, weiterbefördert werden. Eine Vorrichtung dieser Art ist beispielsweise durch die GB-PS 1 150 605 bekannt.When printing notes, in particular banknotes, stocks or similar documents, larger sheets are generally printed with a large number of individual pieces. These sheets are then visually inspected to identify printing errors, with the examiner marking the misprints to be discarded with a fluorescent color. The sheets are then cut into individual pieces and the individual pieces are guided past a detector which responds to the markings. The individual pieces go into a sorting device controlled by this detector, in which the marked misprints are automatically rejected, while the perfect individual pieces are conveyed on for further processing, for example for applying a number print. A device of this type is known for example from GB-PS 1 150 605.

Ausser Sortiervorrichtungen, die mit einer elektromagnetisch gesteuerten Ablenkplatte arbeiten (GB-PS 898 715), sind auch bereits mit einer Ansaugwalze arbeitende Vorrichtungen der im Oberbegriff des Anspruchs 1 beschriebenen Art durch die DE-A-2 711 084 bekannt. Die Ansaugwalze dieser bekannten Vorrichtung erlaubt die Ansaugung auszusondernder Einzelstücke nur an einer einzigen Umfangsstelle, so dass bei jeder vollen Umdrehung der Ansaugwalze lediglich ein einziges Einzelstück gefördert und gegebenenfalls ausgesondert werden kann. Das ist im Falle von Einzelstücken, deren Abmessung in Förderrichtung klein gegenüber der Umfangslänge der Ansaugwalze ist, ungünstig und unwirtschaftlich. Das gilt insbesondere für auf Format geschnittene Wertscheine, insbesondere Banknoten, deren Fertigung mit einer wesentlich grösseren Arbeitsgeschwindigkeit stattfinden sollte, als es einem Arbeitstakt von einem Wertschein je Walzenumdrehung entspricht.In addition to sorting devices which work with an electromagnetically controlled deflection plate (GB-PS 898 715), devices of the type described in the preamble of claim 1 which are already known from DE-A-2 711 084 are also known. The suction roller of this known device allows the suction of individual pieces to be separated out only at a single circumferential point, so that only one single piece can be conveyed and, if necessary, separated out with each full rotation of the suction roller. This is unfavorable and uneconomical in the case of individual pieces, the dimension of which in the conveying direction is small compared to the circumferential length of the suction roll. This applies in particular to notes of value cut to format, in particular banknotes, the production of which should take place at a much greater working speed than corresponds to one working cycle of one note of value per roller revolution.

Es sind auch Transportvorrichtungen für Einzelstücke bekannt (DE-A-2 130 441 und US-A-2 752 154), welche mit einer Ansaugwalze arbeiten, die mehrere über ihren Umfang verteilte Ansaugöffnungen aufweist. Mit derartigen Vorrichtungen lassen sich jedoch lediglich Einzelstücke in einem vorgegebenen Takt transportieren, nich jedoch markierte Einzelstücke aus der rasch transportierten Folge aussondern. Daher herrscht bei diesen bekannten Vorrichtungen innerhalb der den Transportweg difinierenden Winkelbereiche der Ansaugwalzen ständig ein Unterdruck, der nicht kurzzeitig mittels gesteuerter Ventile ein- und abgeschaltet werden muss.Transport devices for individual pieces are also known (DE-A-2 130 441 and US-A-2 752 154), which work with a suction roller which has a plurality of suction openings distributed over its circumference. With such devices, however, only individual items can be transported in a predetermined cycle, but not marked individual items from the rapidly transported sequence. Therefore, in these known devices, there is always a negative pressure within the angular ranges of the suction rollers which differ in the transport path and which does not have to be switched on and off briefly by means of controlled valves.

Bei einer anderen bekannten Sortiervorrichtung (US-A-2.804.974) laufen die Einzelstücke über einen Tisch zu einer Ansaugwalze, die unterhalb des Tisches angeordnet ist und nach oben durch eine im Tisch vorgesehene Oeffnung ragt. Auszusondernde Einzelstücke werden durch diese Oeffnung heruntergezogen.In another known sorting device (US-A-2,804,974), the individual pieces run over a table to a suction roller which is arranged below the table and projects upwards through an opening provided in the table. Individual items to be separated out are pulled down through this opening.

Der Erfindung liegt die Aufgabe zugrunde, die Verarbeitungskapazität einer Vorrichtung der im Oberbegriff des Patentanspruchs 1 beschriebenen Art, das heisst die Anzahl der je Umdrehung der Ansaugwalze geförderten Einzelstücke, zu erhöhen und trotzdem eine einwandfreie Aussonderung der markierten Einzelstücke, unter Aufrechterhaltung eines registerhaltigen Transports der übrigen Einzelstücke, zu gewährleisten.The invention has for its object to increase the processing capacity of a device of the type described in the preamble of claim 1, that is to say the number of individual pieces conveyed per revolution of the suction roller, and nevertheless a perfect rejection of the marked individual pieces while maintaining a register-specific transport of the others Unique pieces, to ensure.

Diese Aufgabe wird erfindungsgemäss durch die im Patentanspruch 1 angegebenen Merkmale gelöst.According to the invention, this object is achieved by the features specified in patent claim 1.

Dadurch wird erreicht, dass je voller Saugwalzenumdrehung vier Einzelstücke gefördert und markierte Einzelstücke individuell ausgesondert werden können.It is thereby achieved that four individual pieces can be conveyed per marked suction roll revolution and marked individual pieces can be separated out individually.

Eine zweckmässige Ausgestaltung der Vorrichtung nach der Erfindung ergibt sich aus dem abhängigen Patentanspruch.An expedient embodiment of the device according to the invention results from the dependent claim.

Die Erfindung wird anhand der Zeichnungen an einem Ausführungsbeispiel näher erläutert. Es zeigen:

  • Figur 1 eine Seitenansicht einer Vorrichtung,
  • Figur 2 einen Schnitt durch die Ansaugwalzen,
  • Figur 3 den Antrieb der Vorrichtung und
  • Figuren 4A bis 4D die einzelnen Arbeitsphasen der Vorrichtung.
The invention is explained in more detail with reference to the drawings using an exemplary embodiment. Show it:
  • FIG. 1 shows a side view of a device,
  • FIG. 2 shows a section through the suction rolls,
  • Figure 3 shows the drive of the device and
  • Figures 4A to 4D, the individual working phases of the device.

Nach der Darstellung in Figur 1 werden die Einzelstücke a, b usw. von Wertpapieren oder dergleichen auf der Förderbahn 1 durch eine Kette C mit Stossfingern P1, P2 usw. in der Zeichnung von links nach rechts befördert. Die Ketten laufen auf Kettenrädern 8, 9 (Figur 3), welche in üblicher Weise angetrieben werden.According to the illustration in FIG. 1, the individual pieces a, b etc. of securities or the like are conveyed on the conveyor track 1 by a chain C with push fingers P1, P2 etc. in the drawing from left to right. The chains run on sprockets 8, 9 (Figure 3), which are driven in the usual way.

Auszusortierende Einzelstücke sind mit fluoreszierender Tinte gekennzeichnet. Ein hierauf ansprechender Detektor 2 ist oberhalb der Förder bahn 1 angeordnet. Dieser Detektor 2 kann ein übliches Gerät sein, welches auf fluoreszierende Tinte anspricht. Es kann aber auch ein Gerät mit einem wechselnden Magnetfeld sein, wenn die auszusortierenden Einzelstücke aus einem Material bestehen, welches Wirbelströme leitet.Individual items to be sorted out are marked with fluorescent ink. A responsive detector 2 is arranged above the conveyor track 1. This detector 2 can be a conventional device which responds to fluorescent ink. However, it can also be a device with a changing magnetic field if the individual pieces to be sorted out are made of a material that conducts eddy currents.

Ein weiterer Detektor 2a ist ein photoelektrisches Gerät zur Ermittlung von Verdoppelungen, d.h. wenn sich zwei Einzelstücke übereinander gelegt haben. In diesem Fall wird die Vorrichtung durch eine Steuereinrichtung 41 angehalten.Another detector 2a is a photoelectric device for determining duplications, i.e. when two individual pieces have been placed on top of each other. In this case, the device is stopped by a control device 41.

Ein anderer Detektor 2b ist ebenfalls ein photoelektrisches Gerät zur Prüfung bestimmter Kennzeichen auf den einzelnen Stücken, womit festgestellt wird, ob diese Einzelstück die richtige Orientierung aufweist.Another detector 2b is also a photoelectric device for checking certain characteristics on the individual pieces, with which it is determined whether this individual piece has the correct orientation.

Ein drittes photoelektrisches Gerät 2c ist ein Zähler.A third photoelectric device 2c is a counter.

Nach Vorbeigang am Detektor 2 gelangen die Wertpapiere zwischen eine sich drehende Ansaugwalze 4 mit vier Saugdüsen 13,14,15 und 16 und eine Andrückwalze 5. Wenn ein auszusonderndes Einzelstück vom Detektor 2 ermittelt wurde, wird ein Elektroventil 19 betätigt, welches eine Unterdruckquelle mit der Ansaugwalze 4 verbindet. Die Ansaugwalze 4 nimmt dann das auszusortierenden Einzelstück auf und fördert es entgegen der Uhrzeigerrichtung in Figur 1 (Pfeil) bis zu einer zweiten Ansaugwalze 6.After passing the detector 2, the securities pass between a rotating suction roller 4 with four suction nozzles 13, 14, 15 and 16 and a pressure roller 5. When an individual item to be separated out has been determined by the detector 2, an electrovalve 19 is actuated, which connects a vacuum source to the suction roller 4. The suction roller 4 then picks up the individual piece to be sorted out and conveys it counterclockwise in FIG. 1 (arrow) to a second suction roller 6.

Diese zweite Ansaugwalze 6 besitzt ebenfalls view Saugdüsen 37, 38, 39 und 40. Diese beiden Ansaugwalzen 4 und 6 sind so zueinander angeordnet, dass die Saugdüsen der Walze 6 mit der Unterdruckquelle zum gleichen Zeitpunkt verbunden wird, an dem diese Verbindung mit der Walze 4 unterbrochen wird, so dass das aufgenommene Einzelstück von der Walze 4 auf die Walze 6 übergeben wird. Dieses Einzelstück wird dann in Uhrzeigerrichtung in Figur 1 (Pfeil) von der Walze 6 an einem Zähler 59 üblicher Ausbildung vorbeigeführt. Dann gelangt dieses Einzelstück zwischen die beiden Walzen 31 und 32 und fällt von dort über eine Führung 33 auf ein Förderband 34, welches das Einzelstück dann auf dem Ablagetisch 35 ablegt.This second suction roller 6 also has view suction nozzles 37, 38, 39 and 40. These two suction rollers 4 and 6 are arranged with respect to one another in such a way that the suction nozzles of the roller 6 are connected to the vacuum source at the same time that this connection with the roller 4 is interrupted so that the recorded individual piece is transferred from the roller 4 to the roller 6. This single piece is then guided clockwise in FIG. 1 (arrow) by the roller 6 past a counter 59 of conventional design. This single piece then passes between the two rollers 31 and 32 and falls from there via a guide 33 onto a conveyor belt 34, which then deposits the single piece on the deposit table 35.

Bei der Ansaugwalze 4 erfolgt die Verbindung ihrer Saugdüsen 13 und 15 mit der Unterdruckquelle mittels eines äusseren Kreisbogenschlitzes 17, während die Saugdüsen 16 und 14 über einen inneren Kreisbogenschlitz 11 mit der Unterdruckquelle verbindbar sind. Diese beiden Schlitze 11 und 17 sind ihrerseits über die Leitungen 11' bzw. 17' mit den ventilen 19 und 19a verbunden. Die Saugdüsen 13 bis 16 sind so angeordnet, dass sie an den vorderen Rändern der auszusortierenden Einzelstücke zur Anlage kommen. Wenn nun ein auszusortierendes Einzelstück vom Detektor 2 ermittelt wird, bewirkt die Schalteinrichtung 41 die Oeffnung des Ventiles 19 und eine Verbindung des Kreisbogenschlitzes 17 mit der Unterdruckquelle. Hierdurch wird an der betreffenden Saugdüse ein Unterdruck erzeugt, sobald diese in Berührung mit dem vorderen Rand des auszusondernden Einzelstückes kommt. Dieser Unterdruck über das Ventil 19 bleibt an der Ansaugwalze 4 etwa während einer Drehung um 140° dieser Walse für jeden Auswerfvorgang aufrechterhalten. Dann wird der Unterdruck durch die Schaltung 41 an die andere Ansaugwalze 6 während ebenfalls einer Umdrehung von etwa 140° angelegt.In the case of the suction roller 4, the connection of its suction nozzles 13 and 15 to the vacuum source takes place by means of an outer circular arc slot 17, while the suction nozzles 16 and 14 can be connected to the vacuum source via an inner circular arc slot 11. These two slots 11 and 17 are in turn connected via lines 11 'and 17' to the valves 19 and 19a. The suction nozzles 13 to 16 are arranged so that they come to rest on the front edges of the individual pieces to be sorted out. If a single piece to be sorted out is now determined by the detector 2, the switching device 41 effects the opening of the valve 19 and a connection of the circular arc slot 17 to the vacuum source. As a result, a negative pressure is generated on the suction nozzle in question as soon as it comes into contact with the front edge of the individual piece to be separated. This negative pressure via the valve 19 is maintained on the suction roller 4 approximately during a rotation through 140 ° of this roller for each ejection process. Then the negative pressure is applied by the circuit 41 to the other suction roller 6 during a rotation of approximately 140 ° as well.

An der Ansaugwalze 6 sind ebenfalls Kreisbogenschlitze 36 und 42 vorgesehen, um über die Ventile 10 und 10a einen Unterdruck an die Saugdüsen 37,3S, 39 und 40 der Ansaugwalze 6 anlegen zu können. Dieser Unterdruck liegt an der Ansaugwalze 6 etwa um 140° später als an der Ansaugwalze 4 an, d.h. erst wenn das auszusondernde Einzelstück in den Spalt zwischen den beiden Walzen 4 und 6 eintritt. Bei einem Unterdruck an dem Kreisbogenschlitz 36 nimmt dann beispielsweise die Saugdüse 37 das auszusondernde Einzelstück auf und befördert es in Uhrzeigerrichtung weiter. Wenn die Saugdüse 37 das obere Ende des Kreisbogenschlitzes 36 verlässt, wird der Unterdruck aufgehoben, und das Einzelstück gelangt zwischen die beiden Walzen 31 und 32 und von dort auf das Förderband 34. Die nächste Saugdüse 40 steht dann mit dem inneren Kreisbogenschlitz 42 in Verbindung. Das Ventil 10 verbindet den Kreisbogenschlitz 42 und das Vential 10a den Kreisbogenschlitz 36 der Ansaugwalze 6 mit der Unterdruckquelle. Alle Detektoren und Ventile sind mit der Schaltung 41 oder einer anderen Steuereinrichtung verbunden.Circular arc slots 36 and 42 are also provided on the suction roller 6 in order to be able to apply a negative pressure to the suction nozzles 37, 3S, 39 and 40 of the suction roller 6 via the valves 10 and 10a. This negative pressure is present at the suction roller 6 approximately 140 ° later than at the suction roller 4, i.e. only when the individual item to be separated out enters the gap between the two rollers 4 and 6. In the event of a negative pressure at the circular arc slot 36, the suction nozzle 37 then picks up the individual piece to be separated out and conveys it further in the clockwise direction. When the suction nozzle 37 leaves the upper end of the circular arc slot 36, the negative pressure is released and the single piece passes between the two rollers 31 and 32 and from there onto the conveyor belt 34. The next suction nozzle 40 is then connected to the inner circular arc slot 42. The valve 10 connects the circular arc slot 42 and the vential 10a connects the circular arc slot 36 of the suction roller 6 with the vacuum source. All detectors and valves are connected to circuit 41 or another control device.

Wenn das nächste Einzelstück aufgenommen werden soll, wird über das Ventil 19a an dem inneren Kreisbogenschlitz 11 ein Unterdruck angelegt. Die Ansaugwalze 6 arbeitet dann in der gleichen Weise.When the next individual item is to be picked up, a vacuum is applied to the inner circular arc slot 11 via the valve 19a. The suction roller 6 then works in the same way.

Von der Figuren 2, 3 und 4 zeigt Figur 2 eine Seitenansicht der Saugeinrichtung. Danach sitzt die Ansaugwalze 4 auf einer Welle 24, welche über ein Zahnrad 18 angetrieben wird. Diese Welle 24 sitzt in einem Rahmen F1, welcher seinerseits drehbar in einem Lager 43 in einem festen Seitenrahmen F gelagert ist. Diese Anordnung gestattet eine Drehung der beiden Walzen 4 und 6 ausserhalb des Getriebes.From Figures 2, 3 and 4, Figure 2 shows a side view of the suction device. Then the suction roller 4 sits on a shaft 24 which is driven by a gear 18. This shaft 24 is seated in a frame F1, which in turn is rotatably supported in a bearing 43 in a fixed side frame F. This arrangement allows the two rollers 4 and 6 to rotate outside of the transmission.

Das Lager 43 trägt auch die Welle 44, auf welcher die obere Ansaugwalze 6, das Antriebszahnrad 48 und eine anderes Zahnrad 52 sitzen.The bearing 43 also carries the shaft 44 on which the upper suction roller 6, the drive gear 48 and another gear 52 are seated.

Der Antrieb für die beiden Ansaugwalzen 4 und 6 erfolgt über ein Antriebszahnrad 45a auf der Welle 45, welches über das Zahnrad 46 und den Zahnriemen 47 mit dem Zahnrad 48 verbunden ist, welches die Welle 4 und über das Zahnrad 52 und den Zahnriemen 51 auch die Welle 24 dreht. Der Zahnriemen 51 läuft zwischen dem Zahnrad 18 und einem Kettenrad 50, so dass die Rückseite dieses Zahnriemens 51 von dem Zahnrad 52 angetrieben wird (Figur 3). Auf diese Weise drehen die beiden Ansaugwalzen 4 und 6 in entgegengesetzten Richtungen (Figur 4). Ein freilaufendes Kettenrad 50a spannt den Zahnriemen 47.The drive for the two suction rolls 4 and 6 takes place via a drive gear 45a on the shaft 45, which is connected via the gear 46 and the toothed belt 47 to the toothed wheel 48, which the shaft 4 and via the gear 52 and the toothed belt 51 also Shaft 24 rotates. The toothed belt 51 runs between the toothed wheel 18 and a chain wheel 50, so that the rear of this toothed belt 51 is driven by the toothed wheel 52 (FIG. 3). In this way, the two suction rolls 4 and 6 rotate in opposite directions (Figure 4). A free-running sprocket 50a tensions the toothed belt 47.

Die Saugdüse 13 und die Saugdüse 15, welche sich auf der Ansaugwalze 4 diametral gegenüberliegend befinden, münden in den äusseren Kreisbogenschlitz 17, während die beiden anderen Saugdüsen 14 und 16, welche ebenfalls diametral einander gegenüberliegen, in den inneren Kreisbogenschlitz 11 münden. Diese beiden Kreisbogenschlitze 11 und 17 befinden sich in einer festen Ventilplatte 12, welche mittels einer Feder 20 gegen die Ansaugwalze 4 gedrückt wird und mittels eines Zapfens 53 in dem Rahmen (Figur 2) gegen Verdrehung gesichert ist.The suction nozzle 13 and the suction nozzle 15, which are diametrically opposite on the suction roller 4, open into the outer circular arc slot 17, while the other two suction nozzles 14 and 16, which are also diametrically opposite one another, open into the inner circular arc slot 11. These two circular arc slots 11 and 17 are located in a fixed valve plate 12 which is pressed against the suction roller 4 by means of a spring 20 and is secured against rotation by means of a pin 53 in the frame (FIG. 2).

Die Ansaugwalze 6 besitzt hierbei zwei Reihen von Vakuumdüsen 38, 38a usw. Diese beiden Reihen sind gegenüber der einen Reihe von Saugdüsen 13 usw. an der Ansaugwalze 4 so angeordnet, dass sie sich axial versetzt beiderseits dieser einen Saugdüsenreihe befinden (Figur 2). Die Saugdüsen 38, 38a und die diametral gegenüberliegenden Saugdüsen 40, 40a an der Ansaugwalze 6 münden in den inneren Kreisbogenschlitz 42 einer festen Ventilplatte 54. Das andere Paar diametral einander gegenüberliegender Saugdüsen 37 und 39 münden in den äusseren Kreisbogenschlitz 36, wie es auch bei der anderen Ansaugwalze 4 der Fall ist.The suction roller 6 here has two rows of vacuum nozzles 38, 38a etc. These two rows are arranged opposite the one row of suction nozzles 13 etc. on the suction roller 4 in such a way that they are axially offset on both sides of this one suction nozzle row (FIG. 2). The suction nozzles 38, 38a and the diametrically opposite suction nozzles 40, 40a on the suction roller 6 open into the inner circular arc slot 42 of a fixed valve plate 54. The other pair of diametrically opposite suction nozzles 37 and 39 open into the outer circular arc slot 36, as is also the case with the other suction roll 4 is the case.

Die Ketten C und C1 laufen über Kettenräder 8 und 8' auf der Antriebswelle 45. Diese Ketten C und C1 laufen auch über Kettenräder 9 am anderen Ende der Ketten (Figur 1).The chains C and C1 run over sprockets 8 and 8 'on the drive shaft 45. These chains C and C1 also run over sprockets 9 at the other end of the chains (Figure 1).

Es ist notwendig, innere und äussere Kreisbogenschlitze vorzusehen, weil nämlich die Kreisbogenschlitze sich über etwa 140°, also mehr als einen Viertelkreis, erstrecken. Wenn daher ein erstes Einzelstück beispielsweise durch eine mit dem Kreisbogenschlitz 17 verbundene Düse auszusondern ist und zu diesem Zwecke dieser Kreisbogenschlitz 17 an die Unterdruckquelle angeschlossen wird und wenn das nächste Einzelstück nicht ausgesondert werden soll, dann darf die nächste Saugdüse nicht mit dem Kreisbogenschlitz 17 in Verbindung stehen, weil diese sonst dieses Einzelstück ebenfalls aufnehmen würde. Deshalb werden Paare von Saugdüsen abwechselnd mit dem äusseren Kreisbogenschlitz 17 und dem inneren Kreisbogenschlitz 11 verbunden.It is necessary to provide inner and outer circular arc slots because the circular arc slots extend over approximately 140 °, that is to say more than a quarter circle. Therefore, if a first individual piece is to be separated out, for example, by a nozzle connected to the circular arc slot 17 and for this purpose this circular arc slot 17 is connected to the vacuum source and if the next individual piece is not to be separated out, then the next suction nozzle must not be connected to the circular arc slot 17 stand, because this would otherwise also include this single piece. Therefore, pairs of suction nozzles are alternately connected to the outer circular arc slot 17 and the inner circular arc slot 11.

Die Kreisbogenschlitze in der Ansaugwalze 4 laufen über einen Kreisbogen von etwa 140°. Die Kreisbogenschlitze in der Ansaugwalze 6 laufen ebenfalls über Kreisbogen von ungefähr 140°. Wenn daher der Detektor 2 anspricht, verbinden die Ventile 19 und 19a entweder den Kreisbogenschlitz 17 oder den Kreisbogenschlitz 11 mit der Unterdruckquelle für etwas mehr als 140°. Die Ventile sind mit dem Detektor 2 über die Schalteinrichtung 41 oder eine andere Steuereinrichtung verbunden, welche das Signal des Detektors 2 über eine Walzendrehung von etwa 140° aufrecht erhält. Die Ventile 10 und 10a verbinden die Unterdruckquelle mit der Ansaugwalze 6 etwa um eine Drehung von 140° später als die Verbindung der Unterdruckquelle mit der Ansaugwalze 4. Auch diese Verbindung besteht während einer Walzendrehung von etwa 140° der Ansaugwalze 6, wonach diese Verbindung unterbrochen wird und das aufgenommene Einzelstück zwischen die Walzen 31 und 32 gelangt und von dort über die Führung 33 von einem Förderband 34 zu dem Aufnahmetisch 35 gefördert wird. Die Schalteinrichtung 41 ist synchronisiert durch eine Steuereinrichtung 55 auf der Welle 45 des Kettenantriebszahnrades 8 (Figur 2).The circular arc slots in the suction roller 4 run over a circular arc of approximately 140 °. The circular arc slots in the suction roller 6 also run over circular arcs of approximately 140 °. Therefore, when the detector 2 responds, the valves 19 and 19a connect either the circular arc slot 17 or the circular arc slot 11 to the vacuum source for a little more than 140 °. The valves are connected to the detector 2 via the switching device 41 or another control device which maintains the signal of the detector 2 over a roll rotation of approximately 140 °. The valves 10 and 10a connect the vacuum source to the suction roller 6 about a rotation of 140 ° later than the connection of the vacuum source to the suction roller 4. This connection also exists during a roller rotation of about 140 ° of the suction roller 6, after which this connection is interrupted and the picked-up single piece arrives between the rollers 31 and 32 and is conveyed from there via the guide 33 by a conveyor belt 34 to the receiving table 35. The switching device 41 is synchronized by a control device 55 on the shaft 45 of the chain drive gear 8 (FIG. 2).

Ein Zähler 58 (Figur 1) zählt die nicht aussortierten Stücke und ein Zähler 59 zählt die aussortierten Einzelstücke. Eine Prüfeinrichtung 60 prüft auf doppelte Dicke aller Einzelstücke. Im Falle einer solchen doppelten Dicke wird die Vorrichtung durch Ausschalten mittels der Schalteinrichtung 41 angehalten. Ein auf Fluoreszenz ansprechender Detektor 61a prüft nochmals auf fluoreszierend gekennnichnete Einzelstücke, welche möglicherweise nicht aussortiert wurden. Der Detektor 62 ist ein photoelektrische Gerät, welches die Orientierung der Einzelstücke prüft. Alle diese Detektoren sind mit der Schalteinrichtung 41 oder einer anderen Steuereinrichtung über ein Kabel verbunden.A counter 58 (FIG. 1) counts the pieces which have not been sorted out and a counter 59 counts the individual pieces which have been sorted out. A test device 60 checks for double thickness of all individual pieces. In the case of such a double thickness, the device is stopped by switching off by means of the switching device 41. A detector 61a which responds to fluorescence checks again for fluorescent, labeled individual pieces which may not have been sorted out. The detector 62 is a photoelectric device which checks the orientation of the individual pieces. All of these detectors are connected to the switching device 41 or another control device via a cable.

Die Figuren 4A, 4B, 4C und 4C zeigen die Arbeitsweise der erfindungsgemäss ausgebildeten Vorrichtung.FIGS. 4A, 4B, 4C and 4C show the mode of operation of the device designed according to the invention.

Hierbei zeigt die Figur 4A ein Einzelstück a, welches von der Saugdüse 13 der Ansaugwalze 4 aufzunehmen ist. Diese Einzelstück a wurde als gekennzeichnet vom Detektor 2 ermittelt, worauf der äussere Kreisbogenschlitz 17 mit der Unterdruckquelle verbunden wurde.

  • Figur 4B zeigt die Walzen nach einer Vierteldrehung gegenüber der Stellung in Figur 4A. Das aufgenommene Einzelstück a wurde hierbei mit der Ansaugwalze 4 befördert. Angenommen, das Einzeistück b soll nicht ausgesondert werden, dann wird der innere Kreisbogenschlitz 11, mit dem die Saugdüse 14 in Verbindung gelangt, nicht an die Unterdruckquelle angeschlossen.
  • Figur 4C zeigt die Walzen nach einer weiteren Vierteldrehung gegenüber der Stellung nach der Figur 4B. Das weitere Einzelstück c wird hierbei wiederum von der Saugdüse 15 aufgenommen, welche mit dem äusseren Kreisbogenschlitz 17 in Verbindung steht. Das erste Einzelstück a ist auf die Ansaugwalze 6 übergeben worden und wird von der Saugdüse 40 gehalten, welche über den Kreisbogenschlitz 42 mit der Unterdruckquelle verbunden ist. Das Einzelstück b wurde nicht aufgenommen und läuft zur weiteren Bedruckung registerhaltig auf der Kette C weiter.
  • Figur 4D zeigt die Walzen nach einer weiteren Vierteldrehung. Das Einzelstück c wurde von der Saugdüse 15 mitgenommen, welche mit dem äusseren Kreisbogenschlitz 17 in Verbindung steht. Wenn das nachfolgende Einzelstück d aufzunehmen und auszusondern ist, wird der innere Kreisbogenschlitz 11 mit der Unterdruckquelle verbunden und bewirkt einen Sog an der Saugdüse 16.
4A shows a single piece a, which is to be picked up by the suction nozzle 13 of the suction roller 4. This single piece a was identified as marked by the detector 2, whereupon the outer circular arc slot 17 was connected to the vacuum source.
  • Figure 4B shows the rollers after a quarter turn from the position in Figure 4A. The recorded single piece a was conveyed here with the suction roller 4. Assuming that the one-piece b should not be discarded, then the inner circular arc slot 11, with which the suction nozzle 14 comes into contact, is not connected to the vacuum source.
  • FIG. 4C shows the rollers after a further quarter turn compared to the position according to FIG. 4B. The further individual piece c is in turn received by the suction nozzle 15, which is connected to the outer circular arc slot 17. The first single piece a has been transferred to the suction roller 6 and is held by the suction nozzle 40, which is connected to the vacuum source via the circular arc slot 42. The individual item b was not recorded and continues to run on the chain C for further printing.
  • Figure 4D shows the rollers after a further quarter turn. The single piece c was carried by the suction nozzle 15, which is connected to the outer circular arc slot 17. If the subsequent individual item d is to be picked up and discarded, the inner circular arc slot 11 is connected to the vacuum source and causes suction on the suction nozzle 16.
