Description

Die Erfindung betrifft eine Fördereinrichtung zum Sammeln und Transportieren von auf einer ersten Förderkette rittlings aufgelegten Druckbogen, die am Ende des Sammelvorgangs durch ein Zwischenförderorgan an der ersten Förderkette erfasst, transportiert und an eine taktgleich nachgeschaltete zweite Förderkette resp. Fördervorrichtung übergeben werden.The invention relates to a conveyor for collecting and Transporting on a first conveyor chain astride Sheets printed at the end of the collection process Intermediate conveyor member detected on the first conveyor chain, transported and to a second equal downstream conveyor chain respectively. Conveying device to be handed over.

Fördereinrichtungen dieser Art sind u.a. bei Sammelheftern bekannt, auf denen Druckbogen am Ende eines Sammelvorgangs geheftet werden.
Es ist weiter bekannt, zwei oder mehr Sammelhefter in einer Reihe aufzustellen, um umfangreichere Druckerzeugnisse produzieren zu können, wobei das abschliessende Heften durch die Heftstation des letzten, in der Reihe stehenden Sammelhefters ausgeführt wird und die Heftstationen der voranstehenden Sammelhefter ausgeschaltet werden.
Dieses Zusammenschalten von Sammelheftern erfordert ein Zwischenförderorgan zwischen zwei Sammelheftern, die die Teilprodukte am Ende des Sammelvorgangs auf einer ersten Förderkette eines Sammelhefters an eine zweite Förderkette eines nachfolgenden Sammelhefters transportieren.
Eine Fördereinrichtung dieser Art ist in der JP - A - 8/143179 offenbart. Die auf einer ersten Förderkette zu Teilprodukten rittlings aufliegend gesammelten Druckbogen werden von an einem umlaufenden Zugmittel befestigten Mitnehmers von der ersten Förderkette über eine stationäre Führungsschiene auf eine zweite Förderkette geschoben. Die Führungsschiene ragt mit ihren Enden in die durch die Förderketten gebildeten Förderbereiche und für den Einlaufbereich der zweiten Förderkette bedarf es einer die Teilprodukte öffnende Vorrichtung, damit ein störungsfreier Uebergang gewährleistet ist.
Conveyors of this type are known, inter alia, saddle stitchers on which printed sheets are stapled at the end of a collection process.
It is also known to place two or more saddle stitchers in a row to produce more extensive printed matter, the final stapling being performed by the stitching station of the last in-line saddle stitcher and the stitching stations of the above saddle stitchers being turned off.
This interconnection of saddle stitchers requires a Zwischenförderorgan between two saddle stitchers that transport the partial products at the end of the collection process on a first conveyor chain of a saddle stitcher to a second conveyor chain of a subsequent saddle stitcher.
A conveyor of this kind is disclosed in JP - A - 8/143179. The printed on a first conveyor chain to partial products astride collected sheet are pushed by attached to a rotating traction means driver from the first conveyor chain via a stationary guide rail on a second conveyor chain. The guide rail protrudes with its ends into the conveyor regions formed by the conveyor chains and for the inlet region of the second conveyor chain, it requires a device which opens the partial products, so that a trouble-free transition is ensured.

Das Schieben der Teilprodukte an der rückwärtigen Kante birgt verschiedene Nachteile. Besteht das Teilprodukt aus dunnen Blättern, kann -insbesondere bei schweren und mit schlechten Gleiteigenschaften versehenen Teilprodukten- die nachlaufende Kante durch den Aufprall des zum Schieben verwendeten Mitnehmers beschädigt und die weitere Verarbeitung beeinträchtigt werden. Auch der Uebergang auf die zweite Förderkette ist bei Teilprodukten aus dünnen Blättern anspruchsvoll.
Ein Schieben von relativ schweren Teilprodukten kann an der Falzinnenkante zu Markierungen oder Schäden am Druckbild führen.
The sliding of the partial products at the rear edge has several disadvantages. If the sub-product consists of thin leaves, the trailing edge may be damaged by the impact of the driver used for pushing, and further processing may be impaired, especially in the case of heavy and poorly gliding sub-products. The transition to the second conveyor chain is demanding in the case of partial products made from thin sheets.
Pushing relatively heavy partial products can lead to markings or damage to the printed image at the folded inner edge.

Insbesondere eignet sich das bekannte Zwischenförderorgan nicht, wenn die Zwischenförderstrecke gekrümmt resp. gebogen ausgebildet ist, weil ein Schieben bzw. Stossen eines Teilproduktes an der nachlaufenden Kante Verformungen im Falzbereich auslösen kann, die bei der Weiterverarbeitung Störungen verursachen. In particular, the known intermediate conveyor is suitable not if the intermediate conveyor section curved or. bent is formed because a pushing or poking a partial product Deformations in the fold area at the trailing edge which can cause disruptions during further processing.

Diese Umstände sind hinderlich, um im Sinne einer optimalen Raumaufteilung eine von der reihenweisen, geraden Anordnung mehrerer Förderketten abweichende Aufstellung von Sammelheftern vornehmen zu können.These circumstances are cumbersome in the sense of an optimal Room layout one of row-by-row, straight arrangement several conveyor chains deviating list of saddle stitchers to be able to make.

Der Erfindung liegt die Aufgabe zugrunde, eine Fördereinrichtung der eingangs genannten Art zu schaffen, bei welcher die Druckprodukte im Bereich des Zwischenförderorgangs sicherer geführt sind und die es gestattet, zwei Förderketten so zu verbinden, dass sie unterschiedliche Förderrichtungen einnehmen.The invention is based on the object, a conveyor of the type mentioned above, in which the Print products in the area of the intermediate conveyor process safer and that allows two conveyor chains to do so connect that they take different directions.

Die Aufgabe ist bei einer gattungsgemässen Sammeleinrichtung dadurch gelöst, dass das die am Ende des Sammelvorgangs an der ersten Förderkette gebildeten Teilprodukte erfassende Zwischenförderorgan an einem umlaufenden Zugmittel befestigte, steuerbare Greifer aufweist, die die an der ersten Förderkette angehobenen Teilprodukte am Falz erfassen und geöffnet an die zweite Förderkette transportieren.
Dadurch werden die Druckprodukte zwischen zwei Förderketten nicht durch Mitnehmer geschoben, sondern durch Greifern erfasst und geführt von der ersten Förderkette zur zweiten Förderkette transportiert. Anstelle einer zweiten Förderkette könnten auch andere beispielsweise diskontinuierlich arbeitende Fördervorrichtungen vorgesehen sein, die die Teilprodukte abschnittsweise weitertransportieren.
The object is achieved in a generic collection device characterized in that the intermediate conveyor element at the end of the collection process on the first conveyor chain detected intermediate conveyor member mounted on a rotating traction means, controllable gripper which detect the raised at the first conveyor chain partial products at the fold and opened to the transport the second conveyor chain.
As a result, the printed products between two conveyor chains are not pushed by drivers, but detected by grippers and transported from the first conveyor chain to the second conveyor chain. Instead of a second conveyor chain and other, for example, discontinuously operating conveyors could be provided, which transport the partial products in sections.

Weist nach einer Weiterbildung der Erfindung das als Greifertransporteur ausgebildete Zwischenförderorgan eine Gelenkkette auf, an welcher die Greifer angeordnet sind, so können die Druckprodukte von der ersten auf die zweite Förderkette auch in eine von der Förderrichtung der ersten Förderkette abweichende Förderrichtung umgelenkt werden. Beispielsweise eine Umlenkung > 0 bis 180°. Dies hat den wesentlichen Vorteil, dass auch sehr lange Fördereinrichtungen platz- bzw. raumsparend aufgebaut werden können. Beispielsweise kann eine solche Fördereinrichtung in einer Ecke eines Gebäudes aufgestellt werden. Bei einer Umlenkung um 180° können Förderketten zweier Sammelhefter parallel zueinander geführt werden. Die Fördereinrichtung kann auch über mehrere Stockwerke eines Gebäudes installiert werden.Indicates according to a development of the invention that as a gripper conveyor trained intermediate conveyor a joint chain on, on which the grippers are arranged, so can the Printed products from the first to the second conveyor chain, too in a deviating from the conveying direction of the first conveyor chain Be redirected conveying direction. For example, one Deflection> 0 to 180 °. This has the significant advantage that even very long conveyors space or space-saving can be built. For example, such a conveyor be placed in a corner of a building. With a deflection by 180 ° conveyor chains two Saddle stitchers are guided parallel to each other. The conveyor can also be spread over several floors of a building be installed.

Ein besonders stabiler Uebergang von der ersten Förderkette zum Zwischenförderorgan ist dann gewährleistet, wenn gemäss einer Weiterbildung der Erfindung eine Aushebevorrichtung vorgesehen ist, welche Teilprodukte von der ersten Förderkette abhebt. Eine solche Aushebevorrichtung weist gemäss einer Weiterbildung der Erfindung ein Aushebeschwert auf, das beispielsweise hochschwingend angetrieben ist. Die Greifer fassen die Teilprodukte dann, wenn sie sich auf dem Aushebeschwert befinden. Dies ergibt einen sicheren und fliessenden Übergang von der ersten Förderkette zum Zwischenförderorgan.
Eine sichere Führung der Druckbogen ergibt sich dann, wenn gemass einer Weiterbildung der Erfindung die Greifer die Teilprodukte an zwei im Abstand zueinander angeordneten Stellen fassen. Diese Stellen befinden sich in Falznähe, vorzugsweise an einem oberen Rand der Teilprodukte und sind in Transportrichtung versetzt. Die Teilprodukte sind dann besonders sicher gefasst und können sich bei einem fliegenden Übergang in einer Lücke nicht verschieben oder sonstwie die vorgesehene Position ändern.
A particularly stable transition from the first conveyor chain to the intermediate conveyor element is ensured if, according to a development of the invention, a lifting device is provided which lifts partial products from the first conveyor chain. Such a lifting device has, according to a development of the invention on a Aushebeschwert, which is driven, for example, high swinging. The grippers grasp the partial products when they are on the Aushebeschwert. This results in a safe and smooth transition from the first conveyor chain to the intermediate conveyor.
A secure guidance of the printed sheet results when, according to a development of the invention, the grippers grasp the partial products at two spaced-apart locations. These locations are near the fold, preferably at an upper edge of the partial products and are offset in the transport direction. The sub-products are then very safe and can not move during a flying transition in a gap or otherwise change the intended position.

Die Fig. 1 zeigt einen Tandem-Sammelhefter 44, der einen Sammelhefter A sowie einen Sammelhefter E aufweist, die inline aufgestellt sind. Die beiden Sammelhefter A + B können grundsätzlich gleich ausgebildet sein. Wie ersichtlich, weist der Sammelhefter A eine Einfachkette 2 auf, die in an sich bekannter Weise Druckbogen 1, insbesondere gefaltete Druckbogen rittlings mittels Mitnehmern 46 in Richtung des Pfeiles 45 transportiert. Teilprodukte 99 sind gesammelte Druckbogen 1, die nicht geheftet sind. Im Bereich einer Doppelsammelkette 3 ist die Einfachkette 2 in bekannter Weise in dieser abgesenkt. Die Druckbogen 1 werden somit von der Einfachkette 2 an die Doppelkette 3 übergeben. Im Bereich der Doppelkette 3 ist eine Heftstation 47 angeordnet, mit welcher -wie an sich bekanntgesammelte Druckbogen 1 am Falz geheftet werden können. Die Heftung erfolgt zwischen den beiden Ketten 32 und 33 (Fig. 4) der Doppelkette 3. In Transportrichtung gesehen nach der Heftstation 47 ist eine Auslage 4 angeordnet, mit welcher die durch die Heftstation 47 gehefteten Fertigprodukte 1' in Richtung des Pfeiles 7 vom Sammelhefter A abgehoben und beispielsweise einem Trimmer 37 (Fig. 5) zugeführt werden können.Fig. 1 shows a tandem saddle stitcher 44, a saddle stitcher A and a saddle stitcher E, the inline are set up. The two saddle stitchers A + B can basically be the same. As can be seen, the Saddle stitcher A a simple chain 2, which in per se known Way sheet 1, in particular folded sheet astride means drivers 46 in the direction of arrow 45th transported. Part products 99 are collected printed sheets 1, that are not stapled. In the area of a double collection chain 3 is the single chain 2 lowered in a known manner in this. The printed sheets 1 are thus of the single chain 2 to the Pass double chain 3. In the area of the double chain 3 is a Stitching station 47 arranged, with which-as per se known Sheet 1 can be stapled to the fold. The Stapling takes place between the two chains 32 and 33 (FIG. 4) the double chain 3. Seen in the direction of transport after the stitching station 47 is arranged a display 4, with which the stapled by the stitching station 47 finished products 1 'in the direction of the arrow 7 lifted off the saddle stitcher A and for example a trimmer 37 (Fig. 5) can be supplied.

Zwischen den beiden Sammelheftern A und B ist eine Lücke 9 vorgesehen, die mit einem Zwischenförderorgan 10 überbrückt ist. Diese Lücke 9 wird durch das vordere Ende 3a der Doppelkette 3 und das hintere Ende 8a einer Einfachkette 8 des Sammelhefters B gebildet. Mit dem Zwischenförderorgan 10 werden die Druckbogen als Teilprodukte 99 von der Doppelkette 3 abgehoben und in Längsrichtung geführt zur Einfachkette 8 des Sammelhefters B transportiert und darauf abgelegt. Das als Takttransporteur ausgebildete Zwischenförderorgan 10 weist mehrere an einem umlaufenden Zugmittel befestigte Greifer 22 auf, wobei das Zugmittel gemäss den Fig. 2 bis 4 aus einer endlosen Gelenkkette 18 besteht, die um ein Antriebsrad 13 und um ein Umlenkrad 14 gelegt ist. Wenigstens im Bereich des unteren Trums ist diese Gelenkkette 18 gemäss den Fig. 2 und 4 in einer unten offenen und im Querschnitt U-förmigen Führungsschiene 16 geführt. Die Gelenkkette 18 weist Kettenglieder 18' auf, die wie ersichtlich, etwa kreuzförmig ausgebildet sind und jeweils einen nach unten ragenden Arm 49 aufweisen, an dem eine Greifvorrichtung 51 befestigt ist. Diese Greifvorrichtungen 51 weisen einen Greifer 22 auf, der zwei Greifarme 27 und 28 besitzt, die jeweils an einem Zahnrad 23 bzw. 24 befestigt sind. Diese Zahnräder 23 und 24 kämmen miteinander und sind jeweils um eine Achse 25 bzw. 26 drehbar gelagert. Das obere Zahnrad ist gemass Fig. 2 mit einem zweiarmigen Hebel 21 verbunden, der unter der Spannung einer Feder 52 mit einer Rolle 20 an einer Steuerschiene 19 anliegt. Wird der Hebel 21 um die Achse 25 im Uhrzeigersinn gedreht, so öffnet sich der Greifer 22 unter Spannung der Feder 52. Bei einer Schwenkbewegung des Hebels 21 im Gegenuhrzeigersinn schliesst der Greifer 22. Mittels der Steuerschiene 19 kann der Greifer 22 also zwangsweise geöffnet und durch Federkraft geschlossen werden. Wie die Fig. 1 zeigt, sind die Greifer 22 in Seitenansicht etwa V-förmig ausgebildet und weisen zwei im Abstand zueinander angeordnete Greifmittel 12 auf, mit denen die Teilprodukte 99 jeweils an ihrem oberen Rand gefasst werden. Die Teilprodukte 99 werden hierbei etwa mittig an zwei im Abstand zueinander angeordneten Stellen durch Klemmung gefasst. Die Klemmkraft kann mit einer Feder 52 auf einen bestimmten Wert eingestellt werden. Wesentlich ist, dass durch das Fassen der Teilprodukte 99 an zwei im Abstand zueinander angeordneten Stellen diese lagestabil geführt werden.Between the two saddle stitchers A and B is a gap 9th provided, which bridges with an intermediate conveyor member 10 is.
