Furthermore, an electronic comparison unit 46, for example in the form of a microprocessor, is provided in the processing unit 40, which is intended to compare digitized images recorded by the image recording device 38 with the digital calibration image E. Depending on this comparison, the further processing station 42 generates the control signals S.
- the image pickup device 38 is directed approximately at right angles to the main surface of the printed products 20, 22, which is predetermined by the mouth 16 of the brackets 12.
- the individually controllable brackets 12 are in turn arranged one behind the other at a distance on in the conveying direction F circumferentially driven conveying member 14.
- the mouths 16 of the clamps 12 are directed towards the bottom, so that the two each held by a clamp 12 printed products 20, 22 are transported in a hanging position.
- a first printed product 20 and a second printed product 22 held together by a clamp 12 such that the edges 24, 24 'are mutually spaced apart.
- the two printed products 20, 22 each have an information field 28, 28 'with identification information 30, 30'.

- the wrong printed products 20, 22 may be, for example, incomplete printed products in which at least the outermost sheet is missing. Furthermore, it is conceivable that the first or second printed product 20, 22 indicated by dashed lines in the two mentioned brackets 12 is missing and the relevant clamp 12 only with a second or first printed product 22 is equipped. The above-mentioned incorrect mounting of the brackets 12 can be recognized by means of the optical-electronic control. If a clamp 12 is equipped only with a single printed product 20 or 22, this can optionally be used for further processing, it then does not need to be discharged.

- Both control levers 56, 60 each have a clamping jaw 62 in their free end regions, wherein the clamping jaws 62 of each control element 52 are directed against each other and aligned for clamping the printed products 20, 22 transported together by a clamp 12.
- the pivotal control lever 60 of each control element 52 is spring-loaded in the direction against the stationary control lever 56. Further, it has a control roller 64, which rolls when turning the control disk 54 - this happens synchronously to the movement of the brackets 12 of the transport device 10 - on a stationary, not shown Steuerkulisse.
- the control link is configured such that the pivotable control lever 60 is kept at a distance from the spring force of the stationary control lever 56, except in a control area in which the control elements 52 with the 12 transported by a clamp 12 printed products 20, 22 in interaction. In this control area, the control roller 14 does not roll on the corresponding link, but the position of the pivotable control lever 60 by the spring force and by the total thickness of the clamped between the jaws 62 printed products 20, 22 is determined.
- the thickness of the clamped printed products 20, 22 is determined by the position of the pivotable control lever 60 with respect to the stationary control lever 56, for example by optical detection and electronic evaluation, as shown in EP 0 897 887 A is known.
- the device 50 can erroneous assemblies, such as in FIG. 4 in the third and fourth bracket 12 from the left and in FIG. 5 are shown in the bracket 12 shown on the left, are detected.
- the device 50 also outputs control signals to the further processing station 42 in order to take into account the misfires in the further processing.
- the optical-electronic control of the first printed products 20 and second printed products 22 transported together by a clamp 12 can be carried out as follows. Whenever a clamp 12 reaches the control point 33, the clamp sensor 34 outputs a trigger signal T to the processing unit 40. This generates and transmits to the image recording device 38 a recording command, whereupon the image recording device 38 'captures an image of the identification information 30 of the first printed product 20. With a time delay dependent on the conveying speed v and the nominal distance B of the leading edges 24, 24 'of the first and second printed products 20, 22, the processing unit 40 sends another recording command to the image recording device 38, which accordingly displays an image of the identification information 30' of the second Druckereiecks 22 receives. The digitized images, which are each transmitted directly to the processing unit 40 by the image recording device 38, are compared with the data of the calibration image E by means of the comparison unit 46.
- control signal S may also be an alarm signal to trigger an alarm upon detection of an incorrectly fitted bracket 12.
- the further processing station 42 may be, for example, a discharge station in order to open the clamps 12 which are not correctly equipped with printed products 20, 22 and to release these printed products from the delivery stream.
- the named operating mode of the control device 36 is particularly suitable when identical printed products 20, 22 are transported with the same identification information 30, 30 '. It can also be determined with this operating mode whether the first and / or second printed products 20, 22 are a correct or a wrong printed product.
- the image acquisition device 38 it is also possible to equip or arrange the image acquisition device 38 in such a way that it obtains an image of the entire image field 32 with the identification information 30, 30 'of the first.
- Printed product 20 and the second printed product 22 can accommodate.
- the processing unit 40 in response to a trigger signal T from each a single recording command to the image pickup device 38 from.
- the image captured by the image field 42 is again compared electronically by means of the comparison unit 46 with a corresponding digitally stored calibration image E and, depending on the result of the comparison, the control device 36 generates a corresponding control signal S and forwards it to the further processing station 42.
- This mode is suitable both for the case in which a first printed product 20 and a second printed product 22 should be transported with the same identification information 30, 30 'held by a clamp 12, as well as in the case where the first printed product 20 and the second Printed product 22 different identification information 30, 30 'have.
- the processing unit 40 responsive to trigger pulses T delayed, generates the capture commands for the imaging device 38.
- the image capture device 38 continuously captures images and forwards the corresponding image data to the processing unit 40. If this receives a trigger signal T, it gives, as a function of the conveying speed v and the nominal distance B between the leading edges 24, 24 'of the first and second print products 20, 22 - a first time window and then a second time window, within which the comparison unit 46 compares the recorded images with the calibration image E. If a recorded image corresponds to the calibration image E within the first and the second time interval, the relevant clamp 12 is correctly populated. Otherwise, a wrong equipment is given.
- the processing unit 40 generates a corresponding control signal as a function of the result of the electronic processing and forwards it to the further processing station 42.
- This operating mode is particularly suitable when first and second printed products 20, 22 are to be transported with the same identification information 30, 30 'and the speed v at which the clamps 12 move can be different. This may for example be the case when the brackets 12 are not attached to a driven conveyor member 14 but are arranged, for example, on carriages or carriages which move freely along a path, for example with a slope.
- the processing unit 40 is in response to a trigger signal T out Time interval free, after which it is checked in the comparison unit 46, whether one of the images taken in this time interval coincides with the calibration image E.
- T out Time interval free is particularly suitable when As shown in the previous example, with different speeds consecutive brackets 12 must be expected.
- the identification information 30, 30 'of the first printed product 20 and of the second printed product 22 are different.
- control signals S are used differently. For example, if it is a stacker, the control signals S may be used to form stacks of a certain number of printed products 20, 22. In this case, staples 12 loaded with wrong printed products 20, 22 will not be opened when moving past the post-processing station 42. This may also be the case when a staple is loaded with only a single printed product, while two printed products 20, 22 are needed to complete the stack.
- the staple sensor 34 it is also conceivable to arrange and form the staple sensor 34 in such a way that it does not detect the movement of a staple 12, but the movement of a printed product 20, 22 into the sensor area.
- the brackets 12 not equipped with at least one printed product 20, 22 are not taken into account in the optical-electronic control.
- the calibration procedure is carried out with the same arrangement as the optical-electronic control. It consists essentially in that by means of the image recording device 38 an image of the identification information 30, 30 'of correctly arranged in a clamp 12 first printed product 20 and second printed product 22nd is made and stored in electronic digital form in the memory 44 for the calibration image E.
- the calibration process can be carried out with the transport device 10 stopped, wherein first of all the correct arrangement of the first and second printed products 22, 22 in the relevant clamp 12 and the settings on the image recording device 38 can be visually checked and fine-adjusted.

Bei einer Kontrollstelle 33 und seitlich der Bewegungsbahn der Klammern 12 und der mit ihnen transportierten Druckereiprodukte 20, 22 befindet sich ein Klammersensor 34, beispielsweise in Form einer Lichtschranke, welcher jeweils ein Triggersignal T erzeugt, wenn sich eine Klammer 12 in seinen Sensorbereich hineinbewegt.At a
Der Klammersensor 34 ist Teil einer optisch-elektronischen Kontrolleinrichtung 36, welche weiter ein Bildaufnahmegerät 38, vorzugsweise in Form einer Videokamera, und eine Verarbeitungseinheit 40 aufweist. Das Bildaufnahmegerät 38 ist mit der Verarbeitungseinheit 40 verbunden, welche ihrerseits Steuersignale S erzeugt, welche, wie mit gestrichelten Linien angedeutet, einer stromabwärts der Kontrolleinrichtung 36 angeordneten Weiterverarbeitungsstation 42 zugeführt werden.The

Die Verarbeitungseinheit 40 weist einen Speicher 44 zur digitalen Speicherung eines Eichbildes E auf. Weiter ist in der Verarbeitungseinheit 40 eine elektronische Vergleichseinheit 46, beispielsweise in Form eines Mikroprozessors, vorhanden, welche dazu bestimmt ist, vom Bildaufnahmegerät 38 aufgenommene digitalisierte Bilder mit dem digitalen Eichbild E zu vergleichen.

Auch die zweite Klammer 12 ist mit einem ersten Druckereiprodukt 20 und einem zweiten Druckereiprodukt 22 in richtiger Lage bestückt. Beim ersten Druckereiprodukt 20 handelt es sich um ein richtiges Produkt mit der zutreffenden Identifikationsinformation 30 im Informationsfeld 28, während es sich beim zweiten Druckereiprodukt 22 um ein falsches Produkt handelt, welches im Bereich des Informationsfeldes 28' keine oder eine falsche Identifikationsinformation 30' trägt.The
Bei den falschen Druckereiprodukten 20, 22 kann es sich beispielsweise um unvollständige Druckereiprodukte handeln, bei welchen mindestens das äusserste Blatt fehlt. Weiter ist es denkbar, dass das in den beiden genannten Klammern 12 gestrichelt angedeutete erste bzw. zweite Druckereiprodukt 20, 22 fehlt und die betreffende Klammer 12 nur mit einem zweiten bzw. ersten Druckereiprodukt 22 bestückt ist. Die oben genannten falschen Bestückungen der Klammern 12 sind mittels der optisch-elektronischen Kontrolle erkennbar. Ist eine Klammer 12 nur mit einem einzigen Druckereiprodukt 20 oder 22 bestückt, kann dieses gegebenenfalls für die Weiterverarbeitung verwendet werden, es braucht dann nicht ausgeschleust zu werden.The wrong printed

Die vierte Klammer 12 ist ebenfalls mit einem ersten Druckereiprodukt 20 und einem zweiten Druckereiprodukt 22 in korrekter Lage bestückt, wobei jedoch am zweiten Druckereiprodukt 22 auf dessen dem ersten Druckereiprodukt 20 abgewandten Seite ein drittes Druckereiprodukt 48 deckungsgleich aufliegt. Sofern dieses dritte Druckereiprodukt 48 eine Identifikation trägt, die der Identifikationsinformation 30' des zweiten Druckereiprodukts 22 entspricht, ist mittels der optisch-elektronischen Kontrolle alleine die falsche Bestückung der Klammer 12 nicht erkennbar.The

Um zusätzlich zur optisch-elektronischen Kontrolle zu überprüfen, ob eine der Klammern 12 mit mehr als zwei Druckereiprodukten 20, 22 bestückt ist, kann stromabwärts der Kontrollstelle 33 eine Vorrichtung 50 zur Kontrolle der Gesamtdicke der gemeinsam von einer Klammer 12 transportierten Druckereiprodukte 20, 22 und gegebenenfalls 48, 48' angeordnet sein. Eine zu diesem Zweck geeignete Vorrichtung zur Kontrolle der Dicke der gemeinsam transportierten Druckereiprodukte 20, 22 ist aus der
Die Vorrichtung weist eine Vielzahl von Kontrollelementen 52 auf, die am Umfang einer Kontrollscheibe 54 äquidistant angeordnet sind und im Wesentlichen aus je einem relativ zur Kontrollscheibe 54 stationären Kontrollhebel 56 und einem relativ zur Kontrollscheibe 54 um eine Schwenkachse 58 verschwenkbaren Kontrollhebel 60 bestehen. Beide Kontrollhebel 56, 60 weisen in ihren freien Endbereichen je eine Klemmbacke 62 auf, wobei die Klemmbacken 62 jedes Kontrollelements 52 gegeneinander gerichtet und für das Einklemmen der gemeinsam von einer Klammer 12 transportierten Druckereiprodukte 20, 22 aufeinander ausgerichtet sind.The device has a plurality of
Der schwenkbare Kontrollhebel 60 jedes Kontrollelements 52 ist in Richtung gegen den stationären Kontrollhebel 56 federbelastet. Ferner weist er eine Steuerrolle 64 auf, die beim Drehen der Kontrollscheibe 54 - dies geschieht synchron zur Bewegung der Klammern 12 der Transporteinrichtung 10 - auf einer stationären, nicht gezeigten Steuerkulisse abrollt. Dabei ist die Steuerkulisse derart ausgestaltet, dass der schwenkbare Kontrollhebel 60 gegen die Federkraft vom stationären Kontrollhebel 56 beabstandet gehalten wird, ausser in einem Kontrollbereich, in welchem das Kontrollelemente 52 mit den von einer Klammer 12 gemeinsam transportierten Druckereiprodukten 20, 22 in Interaktion ist. In diesem Kontrollbereich rollt die Steuerrolle 14 nicht auf der entsprechenden Kulisse ab, sondern ist die Position des schwenkbaren Kontrollhebels 60 durch die Federkraft und durch die gesamte Dicke der zwischen den Klemmbacken 62 eingeklemmten Druckereiprodukte 20, 22 bestimmt.The
Die Dicke der eingeklemmten Druckereiprodukte 20, 22 wird durch die Lage des schwenkbaren Kontrollhebels 60 bezüglich des stationären Kontrollhebels 56 bestimmt, beispielsweise durch optische Erfassung und elektronische Auswertung, wie dies aus der

Fällt dieser Vergleich der Bilder der Identifikationsinformationen 30, 30' des ersten Druckereiprodukts 20 und zweiten Druckereiprodukts 22, mit dem Eichbild E positiv aus, wird ein entsprechendes Steuersignal S erzeugt und an die Weiterverarbeitungsstation 42 abgegeben. Auf dieses Steuersignal S kann jedoch verzichtet werden, falls die Weiterverarbeitungsstation 42 ein entsprechendes Signal S nur dann benötigt, wenn eine der Klammern 12 nicht korrekt bestückt ist.If this comparison of the images of the
Fällt jedoch der Vergleich zwischen den aufgenommenen Bildern und dem Eichbild E für eines der aufgenommenen Bilder oder für beide aufgenommenen Bilder negativ aus, wird ebenfalls ein entsprechendes Steuersignal S erzeugt und der Weiterverarbeitungsstation 42 zugeführt. Dieses Steuersignal S kann auch ein Alarmsignal sein, um beim Erkennen einer falsch bestückten Klammer 12 einen Alarm auszulösen. Bei der Weiterverarbeitungsstation 42 kann es sich beispielsweise um eine Ausschleusstation handeln, um die nicht korrekt mit Druckereiprodukten 20, 22 bestückten Klammern 12 zu öffnen und diese Druckereiprodukte aus dem Förderstrom herauszulösen.However, if the comparison between the recorded images and the calibration image E for one of the recorded images or for both recorded images negative, a corresponding control signal S is also generated and the
Die genannte Betriebsart der Kontrolleinrichtung 36 ist insbesondere dann geeignet, wenn identische Druckereiprodukte 20, 22 mit gleicher Identifikationsinformationen 30, 30' transportiert werden. Mit diesem Betriebsmodus ist auch feststellbar, ob es sich beim ersten und/oder zweiten Druckereiprodukt 20, 22 um ein richtiges oder um ein falsches Druckereiprodukt handelt.The named operating mode of the
Wie weiter oben bereits beschrieben ist es auch möglich, das Bildaufnahmegerät 38 derart auszurüsten bzw. anzuordnen, dass sie ein Bild des gesamten Bildfelds 32 mit den Identifikationsinformationen 30, 30' des ersten.As already described above, it is also possible to equip or arrange the
Druckereiprodukts 20 und des zweiten Druckereiprodukts 22 aufnehmen kann. In diesem Fall gibt die Verarbeitungseinheit 40 auf ein Triggersignal T hin jeweils einen einzigen Aufnahmebefehl an das Bildaufnahmegerät 38 ab. Das vom Bildfeld 42 aufgenommene Bild wird wiederum auf elektronischem Wege mittels der Vergleichseinheit 46 mit einem entsprechenden digital gespeicherten Eichbild E verglichen und in Abhängigkeit vom Resultat des Vergleichs die Kontrolleinrichtung 36 ein entsprechendes Steuersignal S erzeugt und an die Weiterverarbeitungsstation 42 weiterleitet.Printed
Dieser Modus eignet sich sowohl für den Fall, dass jeweils ein erstes Druckereiprodukt 20 und ein zweites Druckereiprodukt 22 mit gleicher Identifikationsinformation 30, 30' von einer Klammer 12 gehalten transportiert werden sollten, als auch für den Fall, dass das erste Druckereiprodukt 20 und das zweite Druckereiprodukt 22 unterschiedliche Identifikationsinformationen 30, 30' aufweisen.This mode is suitable both for the case in which a first printed
Selbstverständlich ist es auch denkbar, den Klammersensor 34 stromaufwärts der Kontrollstelle anzuordnen. In diesem Fall erzeugt die Verarbeitungseinheit 40 auf Triggerimpulse T hin entsprechend verzögert die Aufnahmebefehle für das Bildaufnahmegerät 38.Of course, it is also conceivable to arrange the
In einem weiteren Betriebsmodus ist es möglich; die optisch-elektronische Kontrolle derart durchzuführen, dass das Bildaufnahmegerät 38 fortlaufend Bilder aufnimmt und die entsprechenden Bilddaten an die Verarbeitungseinheit 40 weiterleitet. Erhält diese ein Triggersignal T gibt sie - in Abhängigkeit von der Fördergeschwindigkeit v und dem Sollabstand B zwischen den vorlaufenden Kanten 24, 24' des ersten und des zweiten Druckereiprodukts 20, 22 - ein erstes Zeitfenster und danach ein zweites Zeitfenster frei, innerhalb welchen die Vergleichseinheit 46 die aufgenommenen Bilder mit dem Eichbild E vergleicht. Entspricht innerhalb des ersten und des zweiten Zeitintervalls je ein aufgenommenes Bild dem Eichbild E, ist die betreffende Klammer 12 korrekt bestückt. Andernfalls ist eine Falschbestückung gegeben. Auch hier erzeugt die Verarbeitungseinheit 40 in Abhängigkeit vom Resultat der elektronischen Verarbeitung ein entsprechendes Steuersignal und gibt dieses an die Weiterverarbeitungsstation 42 weiter.In another operating mode it is possible; perform the optoelectronic control such that the
Dieser Betriebsmodus eignet sich insbesondere, wenn erste und zweite Druckereiprodukte 20, 22 mit gleicher Identifikationsinformation 30, 30' zu transportieren sind und die Geschwindigkeit v, mit welcher sich die Klammern 12 bewegen unterschiedlich sein kann. Dies kann beispielsweise dann der Fall sein, wenn die Klammern 12 nicht an einem angetriebenen Förderorgan 14 befestigt sind, sondern beispielsweise an Wagen oder Schlitten angeordnet sind, welche sich frei entlang einer Bahn, beispielsweise mit Gefälle, bewegen.This operating mode is particularly suitable when first and second printed
Wird das Bildaufnahmegerät 38 derart ausgestattet bzw. positioniert, dass es ein Bild des gesamten Bildfeldes 32 mit den Identifikationsinformationen 30, 30' des ersten Druckereiprodukts 20 und zweiten Druckereiprodukts 22 aufnehmen kann, gibt in einem weiteren Betriebsmodus die Verarbeitungseinheit 40 auf ein Triggersignal T hin ein Zeitintervall frei, wonach in der Vergleichseinheit 46 kontrolliert wird, ob eines der in diesem Zeitintervall aufgenommenen Bilder mit dem Eichbild E übereinstimmt. Dieser Betriebsmodus ist insbesondere dann geeignet, wenn wie im vorgängigen Beispiel gezeigt, mit unterschiedlichen Geschwindigkeiten aufeinander folgender Klammern 12 gerechnet werden muss. Weiter eignet er sich auch dann, wenn die Identifikationsinformation 30, 30' des ersten Druckereiprodukts 20 und des zweiten Druckereiprodukts 22 unterschiedlich sind.If the
Je nach Art der Weiterverarbeitungsstation 42 werden die Steuersignale S unterschiedlich verwendet. Handelt es sich beispielsweise um eine Stapeleinrichtung, können die Steuersignale S dazu verwendet werden, Stapel mit einer bestimmten Anzahl von Druckereiprodukten 20, 22 zu bilden. In diesem Fall werden Klammern 12, die mit falschen Druckereiprodukten 20, 22 bestückt sind, beim Vorbeibewegen an der Weiterverarbeitungsstation 42 nicht geöffnet. Dies kann ebenfalls dann der Fall sein, wenn eine Klammer nur mit einem einzigen Druckereiprodukt bestückt ist, während zur Vervollständigung des Stapels noch zwei Druckereiprodukte 20, 22 benötigt werden.Depending on the type of
Es ist auch denkbar, den Klammersensor 34 derart anzuordnen und auszubilden, dass er nicht das Hineinbewegen einer Klammer 12, sondern das Hineinbewegen eines Druckereiprodukts 20, 22 in den Sensorbereich erfasst. In diesem Fall werden die nicht mit wenigstens einem Druckereiprodukt 20, 22 bestückte Klammern 12 bei der optisch-elektronischen Kontrolle nicht berücksichtigt.It is also conceivable to arrange and form the
Der Eichvorgang wird mit derselben Anordnung wie die optisch-elektronische Kontrolle durchgeführt. Sie besteht im Wesentlichen darin, dass mittels des Bildaufnahmegeräts 38 ein Bild der Identifikationsinformation 30, 30' von korrekt in einer Klammer 12 angeordnetem ersten Druckereiprodukt 20 und zweiten Druckereiprodukt 22 gemacht und in elektronisch digitaler Form im Speicher 44 für das Eichbild E abgespeichert wird. Der Eichvorgang kann bei gestoppter Transporteinrichtung 10 durchgeführt werden, wobei vorgängig die korrekte Anordnung des ersten und zweiten Druckereiprodukts 22, 22 in der betreffenden Klammer 12 und die Einstellungen am Bildaufnahmegerät 38 visuell kontrolliert und feinjustiert werden können. Es ist jedoch auch möglich, den Eichvorgang während des Laufs vorzunehmen; in diesem Fall ist es auf einfache Art und Weise möglich, im Betriebsmodus, in welchem von den Identifikationsinformationen 30, 30' jedes der Druckereiprodukte 20, 22 ein eigenes Bild aufgenommen wird, den Zeitverzug zwischen der Aufnahme des ersten Bildes und des zweiten Bildes einzustellen.The calibration procedure is carried out with the same arrangement as the optical-electronic control. It consists essentially in that by means of the
Von Vorteil ist es, wenn für das Eichbild E ein grösserer Ausschnitt aufgenommen wird, als später für die Durchführung der optisch-elektronischen Kontrolle. Für den Bildvergleich können dann die für die optisch-elektronische Kontrolle aufgenommenen Bilder innerhalb des Eichbildes softwaremässig verschoben werden, bis eine maximale Uebereinstimmung gefunden wird. Auf diese Weise kann verhindert werden, dass relativ zum Eichbild E leicht verschobene, jedoch korrekte Druckereiprodukte 20, 22 als Fehler interpretiert werden. Dasselbe gilt auch im umgekehrten Fall, bei welchem für die optisch-elektronische Kontrolle ein grösserer Bildausschnitt aufgenommen wird, als das Eichbild E.It is advantageous if a larger section is taken for the calibration image E than later for the performance of the optical-electronic control. For the image comparison, the images recorded for the optical-electronic control can then be shifted in the software within the calibration image until a maximum agreement is found. In this way it can be prevented that relative to the calibration image E slightly shifted, but correct printed
Insbesondere für die Kontrolle des Transports von Zeitungen, Zeitschriften oder dergleichen, bei welchen die ersten und zweiten Druckereiprodukte 20, 22 gleich bedruckt sind, wird mit Vorteil ein Ausschnitt des Drucks auf den Druckereiprodukten 20, 22 als Identifikationsinformation 30, 30' verwendet.In particular, for the control of the transport of newspapers, magazines or the like, in which the first and second printed
In den Ausführungsbeispielen ist die Kontrolle von mittels Klammern 12 paarweise transportierten Druckereiprodukten 20, 22 beschrieben werden.
