Reststapel at least when removing the printed products in each case a supporting retaining device is switched cyclically.

Vorrichtungen der eingangs genannten Art sind beispielsweise bei der Herstellung von Büchern, Zeitschriften oder Produkten für das Zusammentragen von Druckprodukten zu losen Buchblocks bekannt.Devices of the type mentioned are known, for example, in the production of books, magazines or products for the collation of printed products to loose book block.

Die WO 2005/094164 vermittelt ein Verfahren und eine Vorrichtung bei denen die in einem Schuppenstrom quer zur Transportrichtung eines Förderkanals einer aus umlaufenden Mitnehmern gebildeten Zusammentragvorrichtung zugeführt und dabei das jeweils vorderste Druckprodukt aus dem festklemmenden gefalzten Kanten von einem Greifer einer parallel umlaufenden Beschickungsvorrichtung und seitlich ungeführt aus dem Schuppenstrom gezogen und ausschliesslich im Förderkanal abgelegt wird.The WO 2005/094164 teaches a method and an apparatus in which fed in a scale flow transversely to the transport direction of a conveyor channel formed by a rotating entrainment device and thereby pulled the respective foremost print product from the clamping folded edges of a gripper of a parallel rotating feed device and laterally ungauged from the scale flow and is stored exclusively in the conveyor channel.

Die vorveröffentlichte EP 1 520 817 A1 beschreibt ein Verfahren und eine Vorrichtung, bei denen Druckprodukte zu ungebundenen Buchblocks auf einer Förderstrecke, die durch mehrere Druckprodukteanleger beschickt wird, zusammengetragen werden, wobei die Druckprodukte jeweils in einem Randbereich von einer Vorderseite eines Druckproduktstapels abgehoben und mittels Förderorgan von dem Druckproduktestapel abgezogen werden.The pre-published EP 1 520 817 A1 describes a method and an apparatus in which printed products are formed into unbound book blocks on a conveyor line which is fed by a plurality of print product feeders, wherein the printed products are each lifted in an edge region from a front side of a printed product stack and withdrawn by means of conveying member of the printed product stack.

Eine weitere Vorrichtung zum Vereinzeln und Zusammentragen von Druckprodukten entlang einer Sammelstrecke eines Sammelförderes offenbart die EP-A-1748013 . In einer entlang der Sammelstrecke angeordneten Anlegerstation wird mittels eines Saugers eine Ecke eines untersten Druckprodukts eines Stapels abgekippt. Mit wenigstens zwei an einer umlaufenden Kette eines Zugmittelförderes befestigten, von einander beabstandeten Greifern wird der freistehende Randbereich des untersten Druckprodukts erfasst, das Druckprodukt in Transportrichtung des Sammelförderers vom Stapel abgezogen und über eine geneigte Zuführstrecke des Zugmittelfi5rderes zum Sammelförderer hin transportiert. Direkt vor einem Mitnehmer des Sammelförderers geben die einzeln betätigbaren Greifer das Druckprodukt frei und legen es auf einen bis dahin gebildenten Stapel. Der mehrere Greiferpaare aufweisende Zugmittelförderer benötigt für den Rücklauf der umlaufenden Kette verhältnismässig viel Platz. Damit die Greifer präzise und zeitgleich den freistehenden Randbereich des untersten Druckprodukts erfassen können, sind aufwendige Führungen und Steuerkurven notwendig.Another device for separating and gathering printed products along a collecting path of a collecting conveyor discloses the EP-A-1748013 , In a feeding station arranged along the collecting line, a corner of a lowermost printed product of a stack is tipped off by means of a nipple.

Zuvor werden die Druckprodukte 3, 3' durch die Trennvorrichtung 5 jeweils einzeln an der Unterseite des Druckproduktstapels 2 resp. des Druckproduktereststapels 2' an dem der Rückhaltevorrichtung 9 zugewandten Randbereich / Greifrand 6 nach unten abgehoben, wobei unmittelbar vorher die Rückhaltevorrichtung 9 weggestellt resp. zurückgestellt worden ist (siehe Figur 3). Der Greifrand 6 ist vornehmlich aus einem Falz mehrblättriger Druckprodukte 3'gebildet, kommt jedoch als solcher auch bei einer Blattkante eines Plan- oder Einzelbogens vor. Trennvorrichtung 5 und Rückhaltevorrichtung 9 sind taktverbunden gesteuert, d. h. der Randbereich 6 wird bei zurückgestellter Rückhaltevorrichtung 9 abgehoben und das Druckprodukte 3' bei zugestellter Rückhaltevorrichtung 9 unter dem Druckproduktereststapel 2' hervorgezogen. Die Abzugsvorrichtung 22 weist einen mittels nicht dargestellter, gesteuerter Antriebsvorrichtung parallel zur Abzugsrichtung F pneumatisch oder elektromechanisch linear hin und her angetriebenen Greifer 7 auf (Doppelpfeil 31 in Figur 1), der zwei zum Oeffnen und Schliessen des Greifers 7 vorgesehene Greifbacken 23 aufweist. Der Oeffnungs- und Schliessvorgang kann pneumatisch, elektromechanisch oder mechanisch erfolgen und die Hin- und Herbewegung erfolgt an einer Führungsvorrichtung 24. Beim Abzug eines Druckproduktes 3' von einem Druckproduktestapel 2 wird das Druckprodukt 3' im Randbereich 6 bei zurückgesetzter Rückhaltevorrichtung 9 abgehoben, die Rückhaltevorrichtung 9 schwenkt unmittelbar anschliessend unter den Druckproduktereststapel 2' und der schliessende Greifer 7 erfasst in einer Abzugs- Ausgangsstellung das abgehobene Druckprodukt 3' an dem in Abzugsrichtung F vorderen Ende 8 des Randbereichs resp. des Greifrandes 6 (Eckbereich des Druckproduktes) und zieht es aus dem Magazin 4 heraus zur Ueberführung an eine Fördervorrichtung 37, die der Verarbeitungsstrecke zugeordnet ist. Während dem Abzugsvorgang wird das Druckprodukt 3' gegen Verdrehen entlang einer Führungsanordnung 10 fortbewegt, so lange bis es das Magazin 4 verlässt. Der in Förderrichtung F vorauslaufende Rand 42 des abgezogenen Druckproduktes 3' gelangt zwischen die aus zwei nebeneiander paarweise umlaufenden Transportbändern 38, 39 gebildete Fördervorrichtung 37 auf die Verarbeitungsstrecke, wobei die erforderliche Umlenkung der Transportbänder 38, 39 mittels Umlenkrollen 40 erfolgt. Die Zustellung der Rückhaltevorrichtung 9 erfolgt vorzugsweise durch eine Schwenkbewegung, wie in den Figuren 2 und 3 angedeutet. Hierzu ist die Rückhaltevorrichtung 9 durch drei über die Druckproduktestapelbreite verteilte Hebelelemente 11 ausgebildet, die um eine horizontale, parallel zur Abzugsrichtung F verlaufende Achse 13 schwenkbar an einer Welle 12 befestigt sind.Previously, the printed products 3, 3 'by the separation device 5 each individually on the underside of the printed product stack 2, respectively. of the printed product test stack 2 'at the retainer 9 facing edge region / gripping edge 6 lifted down, immediately before the retainer 9 weggestellt resp. has been deferred (see FIG. 3 ). The gripping edge 6 is formed primarily from a fold of multi-sheet printed products 3 ', but as such also occurs at a sheet edge of a plan or single sheet. Separating device 5 and retaining device 9 are controlled in cycles, ie the edge region 6 is lifted in a restrained restraint device 9 and the printed products 3 'with zuzustterter retaining device 9 under the Druckproduktktereststapel 2' pulled out. The extraction device 22 has a not shown, controlled drive device parallel to the withdrawal direction F pneumatically or electromechanically linearly reciprocally driven gripper 7 (double arrow 31 in FIG FIG. 1 ), which has two provided for opening and closing the gripper 7 gripping jaws 23. The opening and closing operation can be pneumatic, electromechanical or mechanical and the reciprocating motion takes place on a guide device 24. When a printed product 3 'is removed from a printed product stack 2, the printed product 3' is lifted off in the edge region 6 when the retaining device 9 is set back, the retaining device 9 pivots immediately thereafter under the Druckproduktktereststapel 2 'and the closing gripper 7 detects in a deduction initial position the lifted printed product 3' at the front in the withdrawal direction F end 8 of the edge region, respectively. the gripping edge 6 (corner region of the printed product) and pulls it out of the magazine 4 for transfer to a conveyor 37, which is associated with the processing line. During the deduction process the printed product 3 'is moved against rotation along a guide assembly 10 until it leaves the magazine 4. The leading in the conveying direction F edge 42 of the withdrawn printed product 3 'passes between the two adjacent nebeneiander in pairs circulating conveyor belts 38, 39 formed conveyor 37 to the processing line, wherein the required deflection of the conveyor belts 38, 39 by means of guide rollers 40 takes place. The delivery of the retaining device 9 is preferably carried out by a pivoting movement, as in the Figures 2 and 3 indicated. For this purpose, the retaining device 9 is formed by three lever elements 11 which are distributed over the printed product stack width and which are fastened to a shaft 12 so as to be pivotable about a horizontal axis 13 extending parallel to the drawing-off direction F.

Die sich zumindest teilweise über die Druckproduktestapelbreite erstreckende Führungsanordnung 10 besteht aus einem unter dem Druckproduktestapel 2 im Randbereich 6 des Druckproduktes 3, 3' schräg unter die Rückhaltevorrichtung 9 abfallenden Führungsorgan 17, dessen Schräglage etwa dem Abkippwinkel des Greifrandes 6 entspricht, und das an die Druckproduktestapelauflagefläche mit der Oberkante in einem stumpfen Winkel etwa bündig übergeht. Das Führungsorgan 17 weist eine Ausnehmung 18 auf, durch welche die das unterste Druckprodukt 3' erfassende Trennvorrichtung 5 tritt und das Druckprodukt 3' gegen das Führungsorgan 17 zieht (siehe Figur 3). Die Trennvorrichtung 5 besteht aus einem an einem Schwenkarm 14 befestigten Saugkopf 15, der mit einer gesteuerten Vakuumquelle verbunden ist. Sobald der Greifrand 6 dem Führungsorgang 17 gegenüber steht, bewegt sich die Rückhaltevorrichtung 9 in die Arbeitsposition und verhindert dort, dass sich der Randbereich an den Druckproduktereststapel 2' zurückbewegt. Zu diesem Zweck ist an dem unter dem Druckproduktereststapel 2' geschwenkten abgewinkelten Schwenkarmende 16 ein Führungselement 19 befestigt. Sofern die Trennvorrichtung 5 mehrere über den Druckproducktestapel 2 verteilte Schwenkarme 14 resp. Saugköpfe 15 aufweist, erstreckt sich das Führungselement 19 über die Druckproduktestapelbreite; besteht die Trennvorrichtung 5 jedoch nur aus einem, aussschliesslich auf das vordere Greifrandende 8 einwirkenden Schwenkarm 14 und Saugkopf 15, erstreckt sich das Führungselement 19 nur über einen Teil der Druckproduktestapelbreite, sodass die Rückhaltevorrichtung 9 bei der Zustellung 9 mit dem abzuziehenden Druckprodukt 3' nicht kollidiert.The at least partially over the printed product stack width extending guide assembly 10 consists of a below the printed product stack 2 in the edge region 6 of the printed product 3, 3 'obliquely sloping below the retaining device 9 guide member 17, the inclined position corresponds approximately to the Abkippwinkel the gripping edge 6, and that to the printed product stack support surface with the upper edge at an obtuse angle is approximately flush. The guide member 17 has a recess 18 through which the lowermost printed product 3 'detecting separating device 5 occurs and the printed product 3' against the guide member 17 pulls (see FIG. 3 ). The separator 5 consists of a suction head 15 attached to a pivoting arm 14, which is connected to a controlled vacuum source. As soon as the gripping edge 6 opposes the guiding operation 17, the restraint device 9 moves into the working position and prevents there that the edge region moves back to the printed product residual stack 2 '. For this purpose, a guide element 19 is fastened to the angled pivoting-arm end 16 pivoted under the printed product test stack 2 '. If the separation device 5 more over the Druckproducktestapel 2 distributed pivot arms 14, respectively. Suction heads 15, the guide member 19 extends over the printed product stack width; However, the separator 5 consists only of one, Exclusively acting on the front end of the gripping edge 8 pivot arm 14 and suction head 15, the guide member 19 extends over only a portion of the printed product stack width, so that the retainer 9 does not collide at the delivery 9 with the deducted print product 3 '.

Damit das abzuziehende Druckprodukt 3' sich lagemässig nicht verschiebt oder verdrehen kann resp. die im Druckproduktestapel 2 eingenommene Lage beim Abziehen beibehält, gleitet die Falz -oder Blattkante des Greifrandes resp. des Randbereiches 6 an einem Leitorgan 20, das sich nach der Länge der Führungsanordnung 10 erstreckt. Dieses Leitorgan 20 ist an dem Führungsorgan 17 befestigt resp. mit der Rückhaltevorrichtung 9 verbunden. Aus den die Führungsanordnung 10 bildenden Organen 17, 20 und Führungselement 19 entsteht bei zugestellter Rückhaltevorrichtung 9 ein schmaler Förderkanal 33, in welchem die abzuziehenden Druckprodukte 3' geführt sind. Dabei können die Organe oder Führungselemente der Führungsanordnung 10 durch vollwandige oder unterbrochene Führungsflächen ausgebildet sein, solange sie sich zur Führung eignen.Thus the deducted print product 3 'positionally does not shift or twist resp. the position taken in the printed product stack 2 retains the peel, slides the fold or blade edge of the gripping edge, respectively. the edge region 6 on a guide member 20 which extends along the length of the guide assembly 10. This guide member 20 is fixed to the guide member 17, respectively. connected to the retaining device 9. From the guide assembly 10 forming organs 17, 20 and guide member 19 is formed when the restraint device 9 is a narrow conveyor channel 33, in which the deducted printed products 3 'are performed. The organs or guide elements of the guide assembly 10 may be formed by solid or interrupted guide surfaces, as long as they are suitable for leadership.

Zum Greifen des Druckproduktes 3' an dem vorderen Greifrandende 8 kann nach der in Figur 6 gezeigten Variante ein Greifer 7 verwendet werden, der an einer Rückhaltevorrichtung 9 eine Rolle 29 aufweist, die mittels Achse 28 an einem Lagerteil 27 der Rückhaltevorrichtung 9 rotierbar gelagert ist. Die Rolle 29 arbeitet mit einer Tupfrolle 30 zusammen, die um eine Achse 43 rotierbar ist. Die Tupfrolle 30 ist mittels einem hier nicht gezeigten Halter ortsfest gelagert. Die Tupfrolle 30 kann mit einer nicht gezeigten Antriebsvorrichtung kontinuierlich angetrieben sein. Zwischen der Rolle 29 und der Tupfrolle 30 wird das Druckprodukt 3' jeweils am vorderen Greifrandende 8 gefasst und in Abzugsrichtung F vom Druckproduktestapel 2 abgezogen. Die abziehende Kraft auf das Druckprodukt 3' wirkt so lange, wie das Greifmittel 32 mit der Rolle 29 zusammenwirkt. Entsprechend erstreckt sich das Greifmittel 32 in Umfangrichtung und bestimmt den Hub bzw. die Strecke, mit welcher das Druckprodukt 3' vom Druckproduktestapel 2 abgezogen wird. Dies ermöglicht eine kontinuierliche Rotationsbewegung der Tupfrollen 30. Der in der Figur 6 gezeigte Greifer 7 ermöglicht ein vibrationsfreies Abziehen eines Druckproduktes 3'.For gripping the printed product 3 'at the front gripping edge end 8 can after the in FIG. 6 a gripper 7 are used, which has a roller 29 on a retaining device 9, which is rotatably supported by means of axis 28 on a bearing part 27 of the retaining device 9. The roller 29 cooperates with a Duprolle 30 which is rotatable about an axis 43. The dup roll 30 is fixedly mounted by means of a holder, not shown here. The dup roll 30 may be continuously driven by a drive device, not shown. Between the roller 29 and the dup roll 30, the printed product 3 'is taken in each case at the front gripping edge end 8 and withdrawn in the withdrawal direction F from the printed product stack 2. The withdrawing force on the printed product 3 'acts as long as the gripping means 32 cooperates with the roller 29. Accordingly, the gripping means 32 extends in the circumferential direction and determines the stroke or the distance at which the printed product 3 'is withdrawn from the printed product stack 2. This allows a continuous rotational movement of the Duproll 30. The in the FIG. 6 shown gripper 7 allows a vibration-free removal of a printed product 3 '.

Der Greifer 7 kann jedoch auch durch andere geeignete Greifermittel ersetzt werden, die es ermöglichen das vordere Greifrandende 8 zu erfassen und das Druckprodukt 3' vom Druckproduktestapel 2 um eine kurze Strecke abzuziehen, sodass das Druckprodukt 3' von der Fördervorrichtung 37 sofort gefasst werden kann. Um ein Druckprodukt 3' vom Druckproduktestapel 2 abzuheben, wird die Rückhaltevorrichtung 9 durch die Welle 12 in die in Figur 3 gezeigte Position verschwenkt. Eine innere Fläche 46, welche bisher den Druckproduktestapel 2, 2' gestützt hat, ist nun wie ersichtlich frei. Dies gilt ebenfalls entsprechend für die in Figur 4 gezeigte Unterseite 35 des abzuziehenden Druckproduktes 3' sowie für eine sich in Abzugsrichtung F erstreckende Vorderseite 36 des Druckproduktestapels 2. Das Führungselement 19 ist ebenfalls ausgeschwenkt, sodass der oben genannte Förderkanal 33 nicht mehr vorhanden ist. Lediglich das Führungselement 17 befindet sich noch in der ursprünglichen Position. Dieses bildet eine ebenfalls schräg nach unten geneigte oberseitige Fläche 21.However, the gripper 7 can also be replaced by other suitable gripper means, which make it possible to grasp the front gripping edge end 8 and remove the printed product 3 'from the printed product stack 2 by a short distance, so that the printed product 3' can be grasped immediately by the conveying device 37. To lift a printed product 3 'from the printed product stack 2, the retaining device 9 by the shaft 12 in the in FIG. 3 shown pivoted position. An inner surface 46, which has hitherto supported the printed product stack 2, 2 ', is now free, as can be seen. This also applies to the in FIG. 4 shown underside 35 of the deducted print product 3 'as well as for extending in the withdrawal direction F front 36 of the printed product stack 2. The guide member 19 is also swung out, so that the above-mentioned conveyor channel 33 is no longer present. Only the guide element 17 is still in the original position. This forms a likewise obliquely downwardly inclined upper side surface 21st

In einem nächsten Schritt werden die Saugköpfe 15 nach oben in die in Figur 4 gezeigte Position verschwenkt, in welcher diese an der Unterseite 35 des Druckproduktes 3' anliegen. In den Saugköpfen 15 wird nun ein Vakuum erzeugt, sodass das Druckprodukt 3' an die Saugköpfe 15 angezogen wird.In a next step, the suction cups 15 are raised in the in FIG. 4 shown pivoted position in which they rest against the underside 35 of the printed product 3 '. In the suction heads 15, a vacuum is now generated, so that the printed product 3 'is attracted to the suction cups 15.

In einem nachfolgenden Schritt wird die Trennvorrichtung 5 nach unten in die in Figur 5 gezeigte Position verschwenkt und im wesentlichen gleichzeitig wird die Rückhaltevorrichtung 9 in die ebenfalls in Figur 5 gezeigte Stellung eingeschwenkt. Dadurch wird der Förderkanal 33 wieder gebildet. Durch die Haftung der Saugköpfe 15 an der Unterseite 35 des Druckproduktes 3' wird dieses im Randbereich 6 nach unten gegen die Fläche 21 bewegt. Hierbei bildet sich im Druckprodukt 3' ein Knick 45, der sich in der Abzugsrichtung über die gesamte Länge des Druckproduktes 3' erstreckt. Unterhalb des Knicks 45 befindet sich der Randbereich 6 innerhalb des Förderkanals 33. Dieser Randbereich 6 erstreckt sich im wesentlichen bis zum Leitorgan 20, wie die Figur 5 erkennen lässt. Mittels Blasdüsen 25 kann Luft in Richtung des Knicks 45 geblasen werden, sodass sich ein Luftpolster zwischen dem Druckprodukt 3' und dem darüber liegenden Druckprodukt 3 bildet. Dadurch kann die Reibung zwischen diesen beiden untersten Bögen beim Abziehen vermindert werden.In a subsequent step, the separating device 5 is lowered into the in FIG. 5 pivoted position shown and substantially simultaneously, the restraint 9 in the also in FIG. 5 pivoted position shown. As a result, the delivery channel 33 is formed again. Due to the adhesion of the suction heads 15 on the underside 35 of the printed product 3 ', this is moved in the edge region 6 down against the surface 21. Here, in the printed product 3 ', a kink 45 is formed which extends in the withdrawal direction over the entire length of the printed product 3 'extends. Below the bend 45 is the edge region 6 within the conveying channel 33. This edge region 6 extends substantially to the guide member 20, as the FIG. 5 lets recognize. By means of blowing nozzles 25, air can be blown in the direction of the bend 45, so that an air cushion forms between the printed product 3 'and the overlying printed product 3. As a result, the friction between these two lowest sheets when removing can be reduced.

Damit beim Abziehen eines Druckproduktes 3' die darüberliegenden Druckprodukte 3 hinsichtlich ihrer Lage keine Aenderung erfahren, ist an der Rückhaltevorrichtung 9 ein auf die in Abzugsrichtung F vordere Stapelseite 44 einwirkendes Anschlagelement 34 befestigt. Das Anschlagelement 34 befindet sich bei zugestellter Rückhaltevorrichtung 9, also beim Abzug der Druckprodukte 3' jeweils in einer auf den Druckproduktereststapel 2` zurückhaltend einwirkenden Anschlagsposition. Bei zurückgestellter Rückhaltevorrichtung 9, beim Abhebevorgang durch die Trennvorrichtung 5 ist das Anschlagselement 34 ausser Funktion.So that when removing a printed product 3 'the overlying printed products 3 experience no change in their position, a stop member 34 is attached to the retaining device 9 acting on the front in the withdrawal direction F stack side 44. The stop element 34 is located at the delivered restraint device 9, ie when printing products 3 'in each case in a stop position acting restrained on the printed product test stack 2`. When reset restraint device 9, the lifting process by the separator 5, the stop element 34 is out of action.
