Description

Die Erfindung betrifft eine Vorrichtung zum Übergeben von Druckbogen, mit einer ersten und einer zweiten Sammelkette, welche beide einen gemeinsamen Übergabebereich für die Druckbogen aufweisen und zumindest in diesem Übergabebereich seitlich versetzt sowie parallel zueinander angeordnet sind, wobei die erste Sammelkette einen First sowie eine Anzahl Mitnehmer aufweist, welche die rittlings auf dem First liegende Druckbogen in einer Transportrichtung fördern und im Übergabebereich an die zweite Sammelkette abgeben, und wobei die zweite Sammelkette zumindest eine Förderkette mit in einem vordefinierten Abstand zueinander angeordneten Mitnehmer besitzt. Weiterhin betrifft die Erfindung ein mittels der erfindungsgemässen Vorrichtung durchführbares Verfahren sowie einen Sammelhefter, welcher die erfindungsgemässe Vorrichtung umfasst.The invention relates to a device for transferring printed sheets, having a first and a second collecting chain, both of which have a common transfer area for the printed sheets and laterally offset at least in this transfer area and are arranged parallel to each other, wherein the first collecting chain a ridge and a number of drivers which convey the printed sheets astride the ridge in a transporting direction and deliver them to the second collecting chain in the transfer area, and wherein the second collecting chain has at least one conveyor chain with a driver arranged at a predefined distance from each other. Furthermore, the invention relates to a method which can be carried out by means of the device according to the invention and to a saddle stitcher which comprises the device according to the invention.

Druckbogen werden in der Druckweiterverarbeitung unter anderem mittels sogenannter Sammelketten transportiert, welche typischerweise bei Sammelheftern vorkommen. Sammelhefter sind Maschinen, in welchen fertig gedruckte, gefalzte und in Anlegern zwischengelagerte Druckbogen zusammengetragen, ausgerichtet und anschließend in einer Heftmaschine beispielsweise mit einer Rückendrahtheftung versehen werden. Dabei werden die Druckbogen in der Regel zunächst von einer ersten, einfachen Sammelkette in Richtung der Heftmaschine gefördert. Noch vor Erreichen der Heftmaschine werden die Druckbogen von der ersten Sammelkette an eine zweite, doppelte Sammelkette weitergegeben, welche die Druckbogen schliesslich der Heftmaschine zuführt. Es sind auch Lösungen bekannt, bei denen die zweite Sammelkette ebenfalls als einfache Sammelkette ausgebildet ist. Ein wesentlicher Aspekt bei dieser Art der Druckweiterverarbeitung ist es, die Druckbogen so schonend wie möglich zu bearbeiten bzw. von einer Station an die nächsten zu übergeben. Eine Reihe von Vorrichtungen und Verfahren sind entwickelt worden, um die Weitergabe der Druckbogen von einer ersten an eine zweite Sammelkette so schonend wie möglich zu gestalten.Prints are transported in post-press, among other things by means of so-called gathering chains, which typically occur in saddle stitchers. Saddle stitchers are machines in which finished printed, folded and stored in investors printed sheets are collected, aligned and then provided in a stapler, for example with a saddle stitch. As a rule, the printed sheets are first conveyed by a first, simple collecting chain in the direction of the stapler. Even before reaching the stitching machine, the printed sheets are passed from the first gathering chain to a second, double collecting chain, which finally feeds the printed sheets to the stapling machine. Solutions are also known in which the second gathering chain is also designed as a simple gathering chain. An essential The aspect of this type of print finishing is to process the printed sheets as gently as possible or to transfer them from one station to the next. A number of devices and methods have been developed to make the transfer of the signatures from a first to a second gathering chain as gentle as possible.

Die als nächstliegender Stand der Technik betrachtete EP 0881180 A1 offenbart eine Förderanlage zum Zusammentragen und Bearbeiten von Druckbogen. Die Förderanlage umfasst eine erste, einfache und eine zweite, doppelte Sammelkette, sowie einen Übergangsbereich, in dem die einfache in die doppelte Sammelkette einfährt. An der einfachen Sammelkette sind Mitnehmer angeordnet, welche für den Transport der Druckbogen zuständig sind. Jeder Druckbogen liegt rittlings auf einem First der einfachen Sammelkette. Um zu verhindern, dass die Druckbogen unkontrolliert und in einem undefinierten Abstand zueinander transportiert werden, ist ein Mitnehmer hinter jedem Druckbogen angeordnet, so dass dieser in Transportrichtung gefördert wird. Die Mitnehmer sind stehend auf der einfachen Sammelkette befestigt und tauchen im Übergangsbereich ab, während die doppelte Sammelkette den jeweiligen Druckbogen übernimmt. Aufgrund ihrer stehenden Anordnung kippen die Mitnehmer der einfachen Sammelkette beim Abtauchen in Transportrichtung und geben den Druckbogen dabei einen zusätzlichen Schub. Dies kann sich derart auswirken, dass die Druckbogen eine Markierung im hinteren Bereich ihres Falzes bekommen.Considered the closest prior art EP 0881180 A1 discloses a conveyor system for collating and processing printed sheets. The conveyor system comprises a first, a simple and a second, double gathering chain, as well as a transition area, in which the simple enters the double collector chain. At the simple gathering chain drivers are arranged, which are responsible for the transport of the printed sheets. Each sheet lies astride a ridge of the simple saddle chain. In order to prevent that the sheets are transported uncontrolled and at an undefined distance from each other, a driver is arranged behind each signature, so that it is conveyed in the transport direction. The drivers are fixed standing on the simple gathering chain and dive in the transition area, while the double collector chain takes over the respective signature. Due to their standing arrangement, the carriers of the simple gathering chain tilt when diving in the transport direction and give the sheet thereby an additional boost. This can have the effect that the printed sheets get a mark in the back of their fold.

Die EP 1424211 A1 offenbart eine Einrichtung zur Herstellung gebundener Druckerzeugnisse. Hierbei umfasst die Sammelkette seitlich angeordnete Mitnehmer. Am Ende der Sammelkette werden die Druckbogen über eine Stützscheibe in einen Zwischenförderbereich transportiert, von wo sie mittels eines Zwischenförderers über ein Schwert an eine Heftstrecke abgegeben werden. In diesem Fall entspricht die Heftstrecke der oben genannten doppelten Sammelkette. Der Nachteil dieser Lösung ist die Verwendung der zusätzlichen Elemente des Zwischenförderbereichs, wie z.B. der Stützscheibe, was zu einer Verteuerung der Anlage führt.The EP 1424211 A1 discloses a device for producing bound printed products. In this case, the collecting chain comprises laterally arranged drivers. At the end of the gathering chain, the printed sheets are transported via a support disk into an intermediate conveying area, from where they are delivered by means of an intermediate conveyor via a sword to a stitching section. In this case, the stitching section corresponds to the above-mentioned double stitching chain. The disadvantage of this solution is the use of additional elements of the intermediate conveying region, such as the support disk, which leads to an increase in the cost of the system.

Daher besteht die Aufgabe der Erfindung darin, eine Vorrichtung und ein Verfahren aufzuzeigen, mit denen die Übergabe der Druckbogen von der ersten an die zweite Sammelkette sowohl schonend als auch kostengünstig durchgeführt werden kann.Therefore, the object of the invention is to provide a device and a method with which the transfer of the printed sheets from the first to the second collecting chain can be carried out both gently and inexpensively.

Diese Aufgabe wird dadurch gelöst, dass die zweite Sammelkette im Bereich ihrer Mitnehmer eine Aussparung aufweist, welche derart ausgestaltet ist, dass ein jedem Mitnehmer der zweiten Sammelkette zugeordneter Mitnehmer der ersten Sammelkette durch die jeweilige Aussparung hindurch absenkbar ist. Dabei taucht jeder Mitnehmer der ersten Sammelkette im Übergabebereich ab und jeder Mitnehmer der zweiten Sammelkette auf. Ausserdem wird diese Aufgabe durch ein Verfahren zur Verwendung in der erfindungsgemässen Vorrichtung gemäss den Merkmalen der unabhängigen Ansprüche gelöst.This object is achieved in that the second gathering chain has a recess in the region of its driver, which is designed such that a driver of the first collector chain associated with each driver of the second collector chain can be lowered through the respective recess. Each driver of the first gathering chain dives in the transfer area and each driver of the second gathering chain. In addition, this object is achieved by a method for use in the inventive device according to the features of the independent claims.

Bei der erfindungsgemässen Vorrichtung transportiert die erste Sammelkette rittlings auf einem First liegende Druckbogen mittels ihrer Mitnehmer bis in den gemeinsamen Übergabebereich der beiden Sammelketten und übergibt die Druckbogen in diesem Bereich an die jeweils zugeordneten Mitnehmer der zweite Sammelkette.In the device according to the invention, the first gathering chain transported astride a first lying printed sheet by means of their driver into the common transfer area of the two collecting chains and passes the sheets in this area to the respective associated driver of the second gathering chain.

Vorteilhaft weist die zweite Sammelkette auf einer von der ersten Sammelkette abgewandten Seite angeordnete und an der zumindest einen Förderkette befestigte Auflageelemente auf, wobei die Aussparung in Transportrichtung vor oder nach den Mitnehmern der zweiten Sammelkette in den Auflageelementen angeordnet ist oder durch zumindest ein vor oder nach den Mitnehmern der zweiten Sammelkette weggelassenes Auflageelement der zweiten Sammelkette gebildet wird. Jedem Mitnehmer der ersten Sammelkette ist ein Mitnehmer der zweiten Sammelkette derart zugeordnet, dass die Mitnehmer der ersten Sammelkette durch die entsprechenden Aussparungen der Auflageelemente der zweiten Sammelkette hindurch abgesenkt werden können.Advantageously, the second collecting chain on a side facing away from the first collecting chain side and fixed to the at least one conveyor chain support elements, wherein the recess is arranged in the transport direction before or after the drivers of the second gathering chain in the support elements or by at least one before or after the Mitnehmer the second accumulation chain omitted support element of the second accumulation chain is formed. Each driver of the first gathering chain is associated with a driver of the second gathering chain such that the drivers of the first collector chain can be lowered through the corresponding recesses of the support elements of the second collector chain.

Bei dem erfindungsgemässen Verfahren taucht im Übergabebereich jeder Mitnehmer der ersten Sammelkette ab und jeder Mitnehmer der zweiten Sammelkette auf. Dazu werden die Mitnehmer der ersten Sammelkette durch die im Bereich der ihnen jeweils zugeordneten Mitnehmer der zweiten Sammelkette in den Auflageelementen angeordnete Aussparung hindurchgeführt.In the method according to the invention, each driver of the first collector chain emerges in the transfer region and each driver of the second collector chain emerges. To do so, the takers of the first gathering chain are the ones in each of them associated carrier of the second collecting chain in the support elements arranged recess passed.

Die erfindungsgemässe Vorrichtung kommt insbesondere in einem Sammelhefter zum Einsatz.The inventive device is used in particular in a saddle stitcher.

Das Verfahren und die Vorrichtung zur Durchführung des Verfahrens schaffen die Möglichkeit, die Druckbogen schonend von der ersten an die zweite Sammelkette abzugeben.The method and the device for carrying out the method make it possible to deliver the printed sheets gently from the first to the second collector chain.

Die erfindungsgemässe Vorrichtung erlaubt ausserdem, einige Elemente einzusparen. Beispielsweise sind das Stützrad und der Zwischenförderer aus der EP 1424211 A1 nicht mehr notwendig. Dadurch werden die Kosten für die Herstellung und Instandhaltung der Vorrichtung reduziert.The inventive device also allows to save some elements.

Fig. 1 zeigt eine Seitenansicht einer erfindungsgemässen Vorrichtung 1, welche Bestandteil eines nicht weiter dargestellten, mit einer Anzahl von Anlegern und einer Heftmaschine ausgestatteten Sammelhefters ist. Die Vorrichtung 1 ist mit einer ersten, einfachen und einer zweiten, doppelten Sammelkette 2, 3 ausgestattet. Die aus Übersichtlichkeitsgründen nur schematisch dargestellte erste Sammelkette 2 transportiert rittlings auf ihrem First 4 liegende Druckbogen 5 in einer Transportrichtung T mittels einer Anzahl von Mitnehmern 6. Die Mitnehmer 6 sind entlang der ersten Sammelkette 2 in einem Abstand a1 zueinander verteilt. Die erste Sammelkette 2 fährt in einen mit senkrechten, gestrichelten Linien dargestellten Übergabebereich 7 in die zweite Sammelkette 3 ein. In diesem Übergabebereich 7 werden die Druckbogen 5 von der ersten Sammelkette 2 an die zweite Sammelkette 3 abgegeben. Die zweite Sammelkette 3 umfasst eine erste sowie eine zweite Förderkette 8, 9, mit Kettengliedern 8', 9', an denen jeweils Auflageelemente 10, 10' für die Druckbogen 5 angeordnet sind (Fig. 2). An bestimmten Auflageelementen 10, 10' sind Mitnehmer 11, 11' der zweiten Sammelkette 3 befestigt, wozu diese Auflageelemente 11, 11' entsprechend ausgestaltet sein können. Alternativ können die Auflageelemente 10, 10' auch als Mitnehmer 11, 11' ausgebildet sein. Die Mitnehmer 11, 11' sind paarweise gegenüberliegend an der ersten und der zweiten Förderkette 8, 9 der zweiten Sammelkette 3 angeordnet und entlang der Förderketten 8, 9 in einem vordefinierten Abstand a2 zueinander verteilt. Fig. 1 shows a side view of an inventive device 1, which is part of a non-illustrated, equipped with a number of investors and a stapler saddle stitcher. The device 1 is equipped with a first, a simple and a second, double collecting chain 2, 3. The sake of clarity only schematically illustrated first gathering chain 2 transported astride on their ridge 4 lying sheet 5 in a transport direction T by means of a number of drivers 6. The drivers 6 are distributed along the first gathering chain 2 at a distance a1 to each other. The first gathering chain 2 moves into a transfer area 7 shown in vertical dashed lines in the second gathering chain 3. In this transfer area 7, the printed sheets 5 are delivered from the first gathering chain 2 to the second gathering chain 3. The second gathering chain 3 comprises a first and a second conveyor chain 8, 9, with chain links 8 ', 9', on each of which support elements 10, 10 'are arranged for the printed sheets 5 ( Fig. 2 ). At certain support elements 10, 10 'are drivers 11, 11' of the second gathering chain 3 is fixed, to which these support elements 11, 11 'may be configured accordingly. Alternatively, the support elements 10, 10 'also be designed as a driver 11, 11'. The drivers 11, 11 'are arranged in pairs opposite to the first and the second conveyor chain 8, 9 of the second gathering chain 3 and distributed along the conveyor chains 8, 9 at a predefined distance a2 to each other.

Die Auflageelemente 10, 10' der zweiten Sammelkette 3 weisen im Bereich jedes Paares der Mitnehmer 11, 11' und in Transportrichtung T vor oder nach diesem Paar Mitnehmer 11, 11' eine Aussparung 12 auf, durch welche beim Betrieb der Vorrichtung 1 jeweils ein Mitnehmer 6 der ersten Sammelkette 2 abtaucht. Alternativ kann die Aussparung 12 auch durch zumindest ein vor oder nach diesem Paar Mitnehmer 11, 11' weggelassenes Auflageelement 10, 10' der zweiten Sammelkette 3 gebildet werden.The support elements 10, 10 'of the second gathering chain 3 have in the region of each pair of drivers 11, 11' and in the transport direction T before or after this pair of carriers 11, 11 'a recess 12, through which in each case a driver during operation of the device 1 6 of the first gathering chain 2 descends. Alternatively, the recess 12 by at least one before or after this pair of drivers 11, 11 'omitted support element 10, 10' of the second gathering chain 3 are formed.

Das Abtauchen beschreibt eine Bewegung eines Mitnehmers 6, sobald dieser die Transportrichtung T der Druckbogen 5 verlässt und einem an einem nicht dargestellten Maschinenrahmen der Vorrichtung 1 drehbar befestigten ersten Umlenkelement 13a der ersten Sammelkette 2 folgt. Vor jeder Abtauchbewegung eines Mitnehmers 6 der ersten Sammelkette 2 taucht ein Paar Mitnehmer 11, 11' der zweiten Sammelkette 3 auf. Die auftauchenden Mitnehmer 11, 11' folgen dabei einem ebenfalls drehbar am nicht dargestellten Maschinenrahmen der Vorrichtung 1 befestigten, ersten Umlenkelement 14a der zweiten Sammelkette 3. Die erste und die zweite Sammelkette 2, 3 umfassen jeweils ein gleichfalls am Maschinenrahmen der Vorrichtung 1 drehbar befestigtes, zweites Umlenkelement 13b, 14b zur ruhigen Führung der zugehörigen Sammelkette.The immersion describes a movement of a driver 6 as soon as it leaves the transport direction T of the printed sheet 5 and a rotatably mounted on a machine frame, not shown, the device 1 first deflecting element 13a of the first gathering chain 2 follows. Before each Abtauchbewegung a driver 6 of the first gathering chain 2 emerges a pair of carriers 11, 11 'of the second gathering chain 3. The emerging drivers 11, 11 'thereby follow a likewise rotatably mounted on the machine frame of the device 1, not shown, first deflecting element 14a of the second gathering chain 3. The first and the second gathering chain 2, 3 each include a likewise rotatably mounted on the machine frame of the device 1, second deflecting element 13b, 14b for smooth guidance of the associated gathering chain.

Die erste und die zweite Sammelkette 2, 3 sind derart angeordnet, dass die Druckbogen 5 an die zweite Sammelkette 3 abgegeben werden, bevor der diese Druckbogen 5 jeweils transportierende Mitnehmer 6 der ersten Sammelkette 2 abtaucht. Die Druckbogen werden somit im Übergabebereich 7 im Wesentlichen in der gleichen Transportrichtung T befördert, um eine möglichst sanfte Übergabe der Druckbogen 5 zu gewährleisten. Nach der Übergabe werden die Druckbogen 5 auf ihrem weiteren Transportweg durch ein am nicht dargestellten Maschinenrahmen der Vorrichtung 1 befestigtes Schwert 15 von unten gestützt. Das Schwert 15 ist oberhalb der zweiten Sammelkette 3, zwischen deren Förderketten 8, 9 angeordnet und ragt nach oben bis auf die Höhe des Firsts 4 der ersten Sammelkette 2. Durch diese Massnahmen können Markierungen bzw. Beschädigungen an den Druckbogen 5 vermieden werden.The first and the second gathering chain 2, 3 are arranged such that the printed sheets 5 are delivered to the second gathering chain 3, before the respective carrier 6 transporting these printed sheets 5 of the first gathering chain 2 is immersed. The printed sheets are thus conveyed in the transfer region 7 substantially in the same transport direction T in order to ensure the smoothest possible transfer of the printed sheets 5. After the transfer, the printed sheets 5 are supported on their further transport path by a not shown on the machine frame of the device 1 fixed sword 15 from below. The sword 15 is located above the second gathering chain 3, between the conveyor chains 8, 9 and protrudes up to the height of the ridge 4 of the first gathering chain 2. By these measures, marks or damage to the signature 5 can be avoided.

Für beide Sammelketten 2, 3 ist mindestens ein Antrieb vorgesehen. In einer bevorzugten Ausführungsform der erfindungsgemässen Vorrichtung 1 wird ein einziger Antrieb 16 für die erste und die zweite Sammelkette 2, 3 verwendet, welcher diese über eine mechanische Kopplung 17, beispielsweise eine Kette antreibt. Alternativ kann auch ein Zahnriemen oder ein anderes die Synchronisierung der beiden Sammelketten 2, 3 gewährleistendes Element verwendet werden. Der Vorteil bei der Verwendung eines einzigen Antriebs 16 ist eine Einsparung von Kosten. Weiterhin wird eine einfache Synchronisierung der beiden Sammelketten 2, 3 ermöglicht.For both collecting chains 2, 3 at least one drive is provided. In a preferred embodiment of the device 1 according to the invention, a single drive 16 is used for the first and the second gathering chain 2, 3, which drives the latter via a mechanical coupling 17, for example a chain. Alternatively, you can also a toothed belt or another synchronizing the two collecting chains 2, 3 ensuring element can be used. The advantage of using a single drive 16 is a cost savings. Furthermore, a simple synchronization of the two collecting chains 2, 3 is made possible.

In einer weiteren bevorzugten Ausführungsform der erfindungsgemässen Vorrichtung 1 werden die erste und die zweite Sammelkette 2, 3 jeweils von einem nicht dargestellten, eigenen Antrieb bewegt.In a further preferred embodiment of the device 1 according to the invention, the first and second gathering chains 2, 3 are each moved by a drive of their own, not shown.

Die erste und die zweite Sammelkette 2, 3 sind als Endlosketten ausgestaltet und umfassen, nach der Art einer typischen Endlosbandes, jeweils an ihren beiden Enden angeordnete weitere Umlenkelemente 13c, 14c. In den Figuren sind aus Darstellungsgründen nur die im Übergabebereich 7 angeordneten, weiteren Umlenkelemente 13c, 14c gezeigt, d.h. ein Umlenkelement 13c am stromabwärtigen Ende der ersten Sammelkette 2 und eine Umlenkelement 14c am stromaufwärtigen Ende der zweiten Sammelkette 3. Dabei können sowohl die Umlenkelemente 13a, 13b, 13c der ersten Sammelkette 2 als auch die Umlenkelemente 14a, 14b, 14c der zweiten Sammelkette 3 als Kettenrad, Umlenkrolle oder Ähnliches ausgebildet sein. Ebenso können auch feststehende Umlenkelemente, beispielsweise Umlenkkurven verwendet werden.The first and the second gathering chain 2, 3 are designed as endless chains and comprise, after the manner of a typical endless belt, in each case at its two ends arranged further deflecting elements 13c, 14c. In the figures, for purposes of illustration, only the further deflection elements 13c, 14c arranged in the transfer area 7 are shown, i. a deflecting element 13c at the downstream end of the first gathering chain 2 and a deflecting element 14c at the upstream end of the second gathering chain 3. In this case, both the deflecting elements 13a, 13b, 13c of the first gathering chain 2 and the deflecting elements 14a, 14b, 14c of the second gathering chain 3 as Sprocket, pulley or the like may be formed. Likewise, fixed deflection elements, such as deflection curves can be used.

In der dargestellten Ausführungsform weisen beide Sammelketten 2, 3 in Transportrichtung T gleiche Kettenteilungen auf und werden mit gleichen Geschwindigkeiten betrieben. In einer alternativen, nicht dargestellten Ausführungsform besitzen die Sammelketten 2, 3 jeweils eine unterschiedliche Kettenteilung von beispielsweise 14 bzw. 15 Zoll und werden mit entsprechend angepassten Geschwindigkeiten betrieben. Die beiden alternativen Ausführungsformen erlauben eine Anpassung der erfindungsgemässen Vorrichtung 1 an verschiedenen Standards von Druckweiterverarbeitungsmaschinen.In the illustrated embodiment, both gathering chains 2, 3 have the same chain pitches in the transport direction T and are operated at the same speeds. In an alternative embodiment, not shown, the gathering chains 2, 3 each have a different chain pitch of, for example, 14 or 15 inches and are operated at correspondingly adapted speeds. The two alternative embodiments allow an adaptation of the inventive device 1 to various standards of print finishing machines.

Die erste und die zweite Sammelkette 2, 3 werden in Transportrichtung T jeweils mit einer derartigen Kettengeschwindigkeit betrieben, dass die Abtauch- bzw. Auftauchfrequenzen der Mitnehmer 6, 11, 11' gleich sind. Dies ergibt sich aus der Notwendigkeit, dass der Mitnehmer 6 der ersten Sammelkette 2 nur dann abtauchen kann, wenn sich die Aussparung 12 der Auflageelemente 10, 10' im Bereich des zugehörigen Paars Mitnehmer 11, 11' der zweiten Sammelkette 3 in einer entsprechenden Position befindet.The first and the second gathering chain 2, 3 are each operated in the transport direction T with such a chain speed that the Abtauch- or Auftauchfrequenzen the driver 6, 11, 11 'are the same. This results from the necessity that the driver 6 of the first gathering chain 2 can only submerge when the recess 12 of the support elements 10, 10 'in the corresponding pair of carriers 11, 11' of the second gathering chain 3 is in a corresponding position ,

Die Fig. 2 zeigt einen Schnitt durch den Übergabebereich 7 der erfindungsgemässen Vorrichtung 1, entlang der Linie II - II der Figur 1. Die Betrachtungsrichtung ist dabei in Transportrichtung T. Ein flügelförmig ausgebildeter Mitnehmer 6 ist unterhalb des Firsts 4 der ersten Sammelkette 2, diese beidseitig überragend angeordnet. In dieser Ansicht taucht der Mitnehmer 6 der ersten Sammelkette 2 vor dem Paar Mitnehmer 11, 11' der zweiten Sammelkette 3, d.h. in Transportrichtung T hinter diesem ab. Ein weiterer, bereits abgetauchter Mitnehmer 6a der ersten Sammelkette 2 ist dem Mitnehmer 6 in Transportrichtung T vorgelagert. Dabei folgt der abtauchende Mitnehmer 6a zunächst der Krümmung des Umlenkelements 13a. Anschliessend bewegt er sich in einer geraden Linie und wird am in Fig. 1 dargestellten weiteren Umlenkelement 13c der ersten Sammelkette 2 im Wesentlichen entgegengesetzt der Transportrichtung T umgelenkt. In dieser Ausführungsform der erfindungsgemässen Vorrichtung 1 erfährt die erste Sammelkette 2 durch das Umlenkelement 13a eine Ablenkung schräg nach unten, bevor sie durch das weitere Umlenkelement 13c im Wesentlichen entgegengesetzt zur Transportrichtung T umgelenkt wird. Die Ablenkung der ersten Sammelkette 2 trägt dazu bei, die schonende Übergabe der Druckbogen 5 zu verbessern. Die Gründe hierfür werden weiter unten im Zusammenhang mit Fig. 4 durch die Erläuterungen der Kettengeschwindigkeit ersichtlich. Anschliessend wird die erste Sammelkette 2 einschliesslich der an ihr befestigten Mitnehmer 6 mittels des ebenfalls in Fig. 1 dargestellten Umlenkelements 13b erneut umgelenkt und letztlich, mittels des nicht dargestellten, am stromaufwärtigen Ende der ersten Sammelkette 2 angeordneten Umlenkelements 13c, wieder in ihre Ausgangsposition gebracht, so dass dort jeweils ein Mitnehmer 6 zum Transport des nächsten Druckbogens 5 zur Verfügung steht.The Fig. 2 shows a section through the transfer area 7 of the inventive device 1, along the line II - II of FIG. 1 , The viewing direction is in the transport direction T. A wing-shaped trained driver 6 is below the ridge 4 of the first gathering chain 2, this arranged on both sides outstanding. In this view, the driver 6 of the first gathering chain 2 emerges in front of the pair of carriers 11, 11 'of the second gathering chain 3, ie in the transport direction T behind it. Another, already submerged driver 6a of the first gathering chain 2 is the driver 6 upstream in the transport direction T. In this case, the descending driver 6a initially follows the curvature of the deflecting element 13a. Then it moves in a straight line and becomes on in Fig. 1 shown further deflecting element 13c of the first gathering chain 2 substantially opposite to the transport direction T deflected. In this embodiment of the device 1 according to the invention, the first gathering chain 2 is deflected obliquely downwards by the deflecting element 13a, before it is deflected by the further deflecting element 13c substantially opposite to the transporting direction T. The deflection of the first gathering chain 2 helps to improve the gentle transfer of the printed sheets 5. The reasons for this are related below Fig. 4 by explaining the chain speed. Subsequently, the first gathering chain 2 including the driver 6 attached to it by means of the also in Fig. 1 shown deflection deflected again 13b and finally, by means of the deflector 13c, not shown, arranged at the upstream end of the first gathering chain 2, brought back to its original position, so that there is a respective driver 6 for transporting the next sheet 5 available.

In einer anderen, nicht dargestellten Ausführungsform der erfindungsgemässen Vorrichtung 1 sind das erste Umlenkelement 13a und das am stromabwärtigen Ende der ersten Sammelkette 2 angeordnete weitere Umlenkelement 13c identisch.In another, not shown embodiment of the device 1 according to the invention, the first deflecting element 13a and the further deflecting element 13c arranged at the downstream end of the first gathering chain 2 are identical.

Die erste Sammelkette 2 taucht zwischen der ersten und der zweiten Förderkette 8, 9 der zweiten Sammelkette 3 ab. Dabei ist ein Abstand a3 zwischen der ersten und der zweiten Förderkette 8, 9 um eine vordefinierte Sicherheitsdistanz grösser als eine sich quer zur Transportrichtung T erstreckende Breite B der Mitnehmer 6 der ersten Sammelkette 2, wobei die Breite B jeweils durch den Abstand zwischen dem beidseitigen äusseren Abschluss des Mitnehmers 6 definiert ist. Bei der erfindungsgemässen Vorrichtung 1 gibt es je nach Anordnung der Aussparung 12 zwei Möglichkeiten des Abtauchens des Mitnehmers 6, entweder in Transportrichtung T hinter oder vor dem Paar Mitnehmer 11, 11'. In Fig. 2 ist die erste Möglichkeit dargestellt.The first gathering chain 2 emerges between the first and the second conveyor chain 8, 9 of the second gathering chain 3. In this case, a distance a3 between the first and the second conveyor chain 8, 9 by a predefined safety distance greater than a transversely to the transport direction T extending width B of the driver 6 of the first gathering chain 2, wherein the width B in each case by the distance between the two-sided outer Completion of the driver 6 is defined. In the device 1 according to the invention, depending on the arrangement of the recess 12, there are two possibilities of dipping the carrier 6, either in the transport direction T behind or in front of the pair of carriers 11, 11 '. In Fig. 2 is the first possibility presented.

Fig. 3 und Fig. 4 zeigen eine erste bzw. eine zweite Detailansicht der erfindungsgemässen Vorrichtung 1 im Übergabebereich 7. Sie stellen Momentaufnahmen vor und beim Abtauchen eines der Mitnehmer 6 der ersten Sammelkette 2 dar, wobei ebenfalls die erste Möglichkeit der Reihenfolge des Abtauchens, d.h. ein Abtauchen stromauf des Paares der ihm zugeordneten Mitnehmer 11, 11' der zweiten Sammelkette 3 abgebildet ist. Fig. 3 and Fig. 4 They present snapshots before and during descent of one of the driver 6 of the first gathering chain 2, wherein also the first possibility of the order of descent, ie a descent upstream of the pair of associated with him driver 11, 11 'of the second gathering chain 3 is shown.

In Fig. 3 bewegt sich der Mitnehmer 6 noch in Transportrichtung T und fördert dabei einen Druckbogen 5. Das Paar Mitnehmer 11, 11' der zweiten Sammelkette 3 taucht im Übergabebereich 7 auf und übernimmt den Druckbogen 5 vom Mitnehmer 6 der ersten Sammelkette 2. Dabei bewegt sich das Paar Mitnehmer 11, 11' bei der Übernahme im Wesentlichen in Transportrichtung T. Mit anderen Worten stellt Fig. 3 den Moment dar, in dem die Übergabe des Druckbogens von der ersten an die zweite Sammelkette 2, 3 stattfindet.In Fig. 3 moves the driver 6 still in the transport direction T and thereby promotes a sheet 5. The pair of carriers 11, 11 'of the second accumulation chain 3 appears in the transfer area 7 and takes over the sheet 5 from the driver 6 of the first accumulation chain 2. This moves the pair Carrier 11, 11 'in the acquisition essentially in the transport direction T. In other words, provides Fig. 3 the moment in which the transfer of the sheet from the first to the second gathering chain 2, 3 takes place.

Zu dem in Fig. 4 dargestellten Zeitpunkt taucht der Mitnehmer 6 der ersten Sammelkette 2 entlang des hier nicht sichtbaren ersten Umlenkelements 13a in Transportrichtung T hinter den Mitnehmern 11, 11' der zweiten Sammelkette 3 durch die Aussparung 12 ab. Die Mitnehmer 11, 11' haben den Druckbogen 5 bereits übernommen und transportieren diesen in Transportrichtung T weiter auf der zweiten Sammelkette 3. Die Aussparung 12 weist eine sich in Transportrichtung T erstreckende Länge L auf, die derart gewählt ist, dass der Mitnehmer 6 der ersten Sammelkette 2 komplett abtauchen kann, ohne an das der Aussparung 12 nachfolgende Auflageelement 10, 10' anzustossen.To the in Fig. 4 shown time, the driver 6 of the first gathering chain 2 dives along the not visible here first deflecting element 13a in the transport direction T behind the drivers 11, 11 'of the second gathering chain 3 through the recess 12 off. The drivers 11, 11 'have already taken over the printed sheet 5 and transport it further in the transporting direction T on the second collecting chain 3. The recess 12 has a length L extending in the transport direction T, which is chosen such that the driver 6 of the first Collecting chain 2 can completely submerge without to the recess 12 subsequent support element 10, 10 'abut.

Die Beachtung der ausreichenden Länge L der Aussparung 12 ist auch aufgrund eines Geschwindigkeitsvektors des Mitnehmers 6 notwendig. Bei dessen Bewegung in Transportrichtung T zeigt sein Geschwindigkeitsvektor in die gleiche Richtung. Sobald der Mitnehmer 6 der ersten Sammelkette 2 jedoch abtaucht, ist sein Geschwindigkeitsvektor aus einer in Transportrichtung und einer senkrecht zur Transportrichtung T, nach unten zeigenden Komponente zusammengesetzt. Das bedeutet, dass die Geschwindigkeit der ersten Sammelkette 2 und damit auch die des Mitnehmers 6 in Transportrichtung T um die nach unten zeigende Geschwindigkeitskomponente abnimmt. Mit der zweiten Sammelkette 3 bzw. deren Paar zweiter Mitnehmer 11, 11' verhält es sich umgekehrt. Weil die zweite Sammelkette 3 auftaucht, nimmt die in Transportrichtung T zeigende Geschwindigkeitskomponente des jeweils auftauchenden, an der zweiten Sammelkette 3 befestigten Paares der Mitnehmer 11, 11' zu. Schlussfolgernd daraus muss die Änderung der Geschwindigkeitsvektoren beim Abtauchen des Mitnehmers 6 der ersten Sammelkette 2 und beim Auftauchen des Paares der Mitnehmer 11, 11' der zweiten Sammelkette 3 in die Dimensionierung der Aussparung 12 einbezogen werden.The consideration of the sufficient length L of the recess 12 is also necessary due to a speed vector of the driver 6. As it moves in the direction of transport T, its velocity vector points in the same direction. However, as soon as the driver 6 of the first gathering chain 2 is submerged, its velocity vector is composed of a component facing downwards in the transport direction and a component pointing downwards perpendicularly to the transport direction T. This means that the speed of the first gathering chain 2 and thus also of the driver 6 in the transport direction T decreases by the speed component pointing downwards. With the second gathering chain 3 or its pair of second drivers 11, 11 ', it behaves vice versa. Because the second gathering chain 3 appears, the speed component of the respective rising pair attached to the second gathering chain 3 in the transporting direction T increases. In conclusion, the change of the velocity vectors during descent of the driver 6 of the first gathering chain 2 and the emergence of the pair of drivers 11, 11 'of the second gathering chain 3 must be included in the dimensioning of the recess 12.

In Fig. 5 ist die zweite Möglichkeit der Reihenfolge des Abtauchens dargestellt, bei der jeder Mitnehmer 6 der ersten Sammelkette 2 in Transportrichtung T vor dem ihm zugeordneten Paar Mitnehmer 11, 11' der zweiten Sammelkette 3, d.h. stromab dieser Mitnehmer 11, 11' abtaucht.In Fig. 5 the second possibility of the order of descent is shown, in which each driver 6 of the first gathering chain 2 in the transport direction T in front of the associated pair of carriers 11, 11 'of the second gathering chain 3, ie downstream of these drivers 11, 11' immersed.

Fig. 6 zeigt eine schräge Seitenansicht der erfindungsgemässen Vorrichtung, wobei insbesondere sechs Momentaufnahmen A1, A2, A3, A4, A5 und A6 der Lage eines Mitnehmers 6 der ersten Sammelkette 2 mit zugehörigen Pfeilen dargestellt sind. Fig. 6 shows an oblique side view of the inventive device, in particular six snapshots A1, A2, A3, A4, A5 and A6 of the position of a driver 6 of the first gathering chain 2 are shown with associated arrows.

In einer ersten Momentaufnahme A1 transportiert der Mitnehmer 6 den Druckbogen 5 rittlings auf der ersten Sammelkette 2 in Transportrichtung T.In a first snapshot A1, the carrier 6 transports the printed sheet 5 astride the first gathering chain 2 in the transporting direction T.

In einer zweiten Momentaufnahme A2 befindet sich der Mitnehmer 6 bereits im hier nicht dargestellten Übergabebereich 7, in dem sich ein auftauchendes Paar Mitnehmer 11, 11' der zweiten Sammelkette 3 dem Mitnehmer 6 der ersten Sammelkette 2 nähert.In a second snapshot A2, the driver 6 is already in the transfer region 7, not shown here, in which an emerging pair of carriers 11, 11 'of the second collector chain 3 approaches the driver 6 of the first collector chain 2.

In einer dritten Momentaufnahme A3 befindet sich der Mitnehmer 6 kurz vor dem Abtauchen an dem hier nicht sichtbaren erste Umlenkelement 13a der ersten Sammelkette 2 und das Paar Mitnehmer 11, 11' der zweiten Sammelkette 3 ist bereits vollständig aufgetaucht.In a third snapshot A3, the driver 6 is located shortly before the descent on the not visible here first deflecting element 13a of the first gathering chain 2 and the pair of carriers 11, 11 'of the second gathering chain 3 has already fully surfaced.

In einer vierten Momentaufnahme A4 taucht der Mitnehmer 6 der ersten Sammelkette 2 durch die Aussparung 12 hindurch komplett in die zweite Sammelkette 3 ein und hat den Druckbogen 5 an das sich bereits im Wesentlichen in die Transportrichtung T bewegende Paar Mitnehmer 11, 11' der zweiten Sammelkette 3 abgegeben.In a fourth snapshot A4, the driver 6 of the first gathering chain 2 emerges completely through the recess 12 into the second gathering chain 3 and has the printed sheet 5 against the pair of carriers 11, 11 'of the second gathering chain which are already moving substantially in the transport direction T. 3 delivered.

In einer fünften Momentaufnahme A5 bewegt sich der Mitnehmer 6, nach der Umlenkung durch das Umlenkelement 13c der ersten Sammelkette 2, im Wesentlichen entgegengesetzt zur Transportrichtung T.In a fifth snapshot A5, the driver 6 moves, after the deflection by the deflecting element 13c of the first gathering chain 2, substantially opposite to the transport direction T.

In einer sechsten Momentaufnahme A6 hat der Mitnehmer 6 der ersten Sammelkette 2, gerade die hier nicht sichtbare Aussparung 12 der Auflageelemente 10, 10' der zweiten Sammelkette 3 im Bereich eines ihm zugeordneten, auftauchenden Paars Mitnehmer 11, 11' der zweiten Sammelkette 3 passiert. Anschliessend wird der Mitnehmer 6 zum Ausgangspunkt zurückgeführt, wo er erneut zum Transport eines Druckbogens 5 zur Verfügung steht.In a sixth snapshot A6, the driver 6 of the first gathering chain 2 has just passed the not visible recess 12 of the support elements 10, 10 'of the second gathering chain 3 in the region of an associated, emerging pair of carriers 11, 11' of the second gathering chain 3. Subsequently, the driver 6 is returned to the starting point, where it is again available for transporting a printing sheet 5 available.

Um sowohl beim ersten als auch beim zweiten Passieren der Aussparung 12 eine Synchronisierung zu gewährleisten, müssen mehrere Parameter der erfindungsgemässen Vorrichtung 1 aufeinander abgestimmt sein. Dies sind im Wesentlichen die Teilung und die Geschwindigkeit sowie die Länge der Überschneidung der beiden Sammelketten 2, 3.In order to ensure synchronization both during the first and during the second passage of the recess 12, a plurality of parameters of the device 1 according to the invention must be matched to one another. These are essentially the Pitch and the speed and length of the intersection of the two gathering chains 2, 3.

Natürlich kann die zweite Sammelkette 3 statt als doppelte Sammelkette mit zwei Förderketten 8, 9 auch als einfache Sammelkette mit einer einzigen Förderkette 8 ausgebildet sein, welche zumindest im Übergabebereich 7 seitlich versetzt und parallel zur ersten Sammelkette 2 angeordnet ist, so wie dies ebenfalls der Fig. 1 entnommen werden kann. In diesem Fall fährt die erste Sammelkette 2 nicht in die zweite Sammelkette 3 ein, sondern verläuft im Übergabebereich 7 neben der zweiten Sammelkette 3 und ebenfalls parallel zu dieser.Of course, the second gathering chain 3 may be formed instead of a double collector chain with two conveyor chains 8, 9 as a simple collector chain with a single conveyor chain 8, which is laterally offset at least in the transfer area 7 and parallel to the first collection chain 2, as well as the Fig. 1 can be removed. In this case, the first gathering chain 2 does not enter the second gathering chain 3, but runs in the transfer area 7 next to the second gathering chain 3 and also parallel to it.

Obwohl vorteilhafte Ausführungsformen der Erfindung gezeigt und beschrieben werden, ist die Erfindung nicht auf diese beschränkt, sondern sie kann im Rahmen des Geltungsbereiches der folgenden Ansprüche auf andere Weise ausgeführt und angewendet werden.While advantageous embodiments of the invention have been shown and described, the invention is not limited to them, but may be otherwise practiced and practiced within the scope of the following claims.
