Description

Die Erfindung betrifft eine Förderanlage zum Zusammentragen und Bearbeiten von Druckbogen, mit einer sattelförmigen Sammel- und einer Doppelkette, mit einem Uebergabebereich, in dem die Sammelkette in die Doppelkette einfährt und mit Mitnehmern für die Druckbogen, die hintereinander an der Sammelkette angeordnet sind. Die Erfindung betrifft zudem eine Sammelkette, insbesondere für eine Förderanlage gemäss Anspruch 1.The invention relates to a conveyor system for collating and processing of printed sheets, with a saddle-shaped collecting and a double chain, with a transfer area in which the collection chain enters the double chain and with drivers for the printed sheets arranged one behind the other on the collection chain are. The invention also relates to a collection chain, in particular for a conveyor system according to claim 1.

Durch die CH - A - 667 253 des Anmelders ist eine Förderanlage für Druckbogen bekannt geworden, die eine Hilfskette aufweist, welche eine Lücke zwischen dem Ende eines ersten Förderkettentrums und dem Anfang eines zweiten Förderkettentrums überbrückt. Bei dieser Förderanlage können die Druckbogen seitlich der Hilfskette sowohl von innen als auch von aussen annähernd bis zum Falz bearbeitet werden. Insbesondere ist damit ein Beschriften mit einer Ink-Jet-Vorrichtung bis in die dem Falz benachbarten Bereiche ohne grösseren Aufwand möglich. The applicant's CH - A - 667 253 is a conveyor system become known for printed sheets that have an auxiliary chain, which is a gap between the end of a first conveyor chain center and bridged the beginning of a second conveyor chain center. With this conveyor system, the printed sheets can be moved laterally the auxiliary chain both from the inside and from the outside processed to the fold. In particular, this is a Label with an ink jet device right down to the fold neighboring areas without much effort.

Bekannt ist auch eine Förderanlage mit einer Sammelkette, die Mitnehmer in der Form von seitlich abstehenden Hörnern aufweist. Die Sammelkette ist eine Einzelkette und hat damit gegenüber einer Doppelkette den Vorteil, dass auch über grosse Sammelstrecken keine Teilungsdifferenzen auftreten können. Die Sammelkette taucht im Uebergabebereich in eine Doppelkette ein. Auf dieser Doppelkette können die Druckprodukte geheftet werden, da die Doppelkette einen Zwischenraum für den Umbiegemechanismus der Hefteinrichtung aufweist. Nachteilig ist bei dieser Förderanlage die insbesondere für kleine Formate nicht optimale Bauform der Doppelkette.A conveyor system with a collection chain is also known Has driver in the form of laterally protruding horns. The collection chain is a single chain and thus has opposite the advantage of a double chain that even over large Collection routes no division differences can occur. The Collection chain dives into a double chain in the transfer area on. The printed products can be stapled on this double chain because the double chain creates a space for the bending mechanism the stapler. The disadvantage is this conveyor system, especially for small formats optimal design of the double chain.

Der Erfindung liegt die Aufgabe zugrunde, eine Förderanlage der genannten Art zu schaffen, welche den genannten Nachteil vermeidet und die bei gleicher oder höherer Leistung dennoch funktionssicher ist und sich für alle Formate eignet.
Die Aufgabe ist bei einer gattungsgemässen Förderanlage dadurch gelöst, dass die Mitnehmer auf der Sammelkette stehend befestigt sind.
Die nun mögliche schmale Bauform der Sammelkette und die Anordnung der Mitnehmer auf dem First der Sammelkette erlauben die Ausbildung auch einer entsprechend schmalen Doppelkette, was das Erfassen und Verarbeiten kleiner Druckbogen ausserordentlich erleichtert. Eine schmale Sammelkette ermöglicht zudem beim Zusammentragen das Erfassen der Druckbogen näher am Falz.The invention has for its object to provide a conveyor system of the type mentioned, which avoids the disadvantage mentioned and which is still functionally reliable with the same or higher performance and is suitable for all formats.
The task is solved in a generic conveyor system in that the drivers are fixed standing on the collection chain.
The now possible narrow design of the collecting chain and the arrangement of the drivers on the ridge of the collecting chain also allow the formation of a correspondingly narrow double chain, which greatly facilitates the detection and processing of small printed sheets. A narrow collection chain also enables the printed sheets to be grasped closer to the fold.

Das Abtauchen der Mitnehmer der Sammelkette im Uebergabebereich gestattet eine optimale Nutzung der Teilung an der Sammelkette; die Teilung wird somit durch das Wegschwenken der abgetauchten Mitnehmer nicht verkürzt.
Ein weiterer Vorteil der erfindungsgemässen Förderanlage wird darin gesehen, dass die Druckbogen beim Ablegen auf die Sammelkette weniger geöffnet werden müssen, was besonders bei hohen Laufgeschwindigkeiten vorteilhaft ist.
Vorteilhaft ist zudem, dass der Aufbau der Doppelkette im grundsätzlichen Aufbau nicht geändert werden muss.
Nach einer Weiterbildung der Erfindung sind die Mitnehmer der Sammelkette wenigstens in Laufrichtung nach vorne geneigt. Die besondere Ausbildung der Mitnehmer der Sammelkette hat den Vorteil, dass dadurch ein günstiger Einfluss auf das Aufprallverhalten und Beschleunigen eines Druckbogens beim Ablegen auf die Sammelkette entsteht. Während beim üblichen, senkrechten Mitnehmer ein aufzulegendes Druckprodukt nach oben prallen und wegspringen kann, wird durch den abgewinkelten Mitnehmer das Produkt auf die Sammelkette zurückgeworfen. Das Druckprodukt kann somit nicht über den Mitnehmer springen und entprechend kann der Mitnehmer kürzer ausgebildet sein als bei einer gestreckten Ausführung des Mitnehmers.The submergence of the drivers of the collection chain in the transfer area allows optimal use of the division on the collection chain; the division is not shortened by swiveling the submerged drivers away.
Another advantage of the conveyor system according to the invention is seen in the fact that the printed sheets do not have to be opened as much when they are placed on the collecting chain, which is particularly advantageous at high running speeds.
It is also advantageous that the basic structure of the double chain does not have to be changed.
According to a development of the invention, the drivers of the collecting chain are inclined forward at least in the running direction. The special design of the carriers of the collection chain has the advantage that this has a favorable influence on the impact behavior and acceleration of a printed sheet when it is placed on the collection chain. While with the usual, vertical driver, a printed product to be placed can bounce upwards and jump away, the angled driver throws the product back onto the collecting chain. The printed product can therefore not jump over the driver and, accordingly, the driver can be made shorter than in a straight version of the driver.

Weitere vorteilhafte Merkmale ergeben sich aus den abhängigen Patentansprüchen, der nachfolgenden Beschreibung sowie der Zeichnung.Further advantageous features result from the dependent ones Claims, the description below and the Drawing.

Die in Figur 1 gezeigte Förderanlage 1 weist eine endlos umlaufende Sammelkette 2 sowie eine ebenfalls endlos umlaufende Doppelkette 3 auf. Die Sammelkette 2 dient in an sich bekannter Weise zum Zusammentragen von Druckprodukten 4, die auf der Doppelkette 3 weiterverarbeitet, beispielsweise geheftet oder adressiert werden. Die Sammelkette 2 ist eine Gliederkette und läuft um das Kettenrad 6, während die Doppelkette 3 um das Kettenrad 7 läuft. Die beiden Kettenräder 6 und 7 sind mit einem Uebertrieb 8 miteinander verbunden. Vorzugsweise wird die Doppelkette 3 mit einem hier nicht gezeigten Antrieb angetrieben. Der Antrieb der Sammelkette 2 erfolgt somit über die Doppelkette 3. An der Sammelkette 2 sind in gleichen Abständen B Mitnehmer 5 angebracht, die beim aktiven Trum 2a wie in Figur 1 ersichtlich nach oben vorstehen. Die Doppelkette 3 besitzt ebenfalls in gleichen Abständen C Mitnehmer 9, die jedoch gemäss Figur 2 seitlich abstehen. Jeder Mitnehmer 9 besteht hier aus zwei seitlich vorstehenden Flügeln 9a.The conveyor system 1 shown in Figure 1 has an endlessly rotating Collection chain 2 and an endless chain Double chain 3 on. The collection chain 2 is used in a manner known per se Way to collate printed products 4 that are on the Double chain 3 further processed, for example stapled or can be addressed. The collection chain 2 is a link chain and runs around the sprocket 6, while the double chain 3 around the Sprocket 7 runs. The two sprockets 6 and 7 are with an overdrive 8 connected to each other. Preferably the double chain 3 driven with a drive, not shown here. The collection chain 2 is thus driven via the double chain 3. At the collection chain 2 are at equal intervals B driver 5 attached to the active strand 2a as protrude upward in FIG. 1. The double chain 3 also has C carriers 9 at equal intervals, which but protrude laterally according to Figure 2. Each driver 9 here consists of two laterally projecting wings 9a.

Die Sammelkette 2 fährt in einem Uebergabebereich A zwischen die Doppelkette 3 ein und läuft nach diesem Bereich A um das Kettenrad 6. Hierbei ist die Sammelkette 2 vor dem Kettenrad 7 auf einer Führungsschiene 14 und nach dem Kettenrad 6 auf einer Führungsschiene 15 geführt. Zwischen den beiden Kettenrädern 6 und 7 taucht der aktive Trum 2a der Sammelkette 2 in die Doppelkette 3 ein. Die Mitnehmer 5 sind im Bereich des Kettenrades 7 oben an der Doppelkette 3 vollständig vorstehend und im Bereich des Kettenrades 6 ganz oder teilweise untergetaucht. Im Uebergabebereich A werden die Druckprodukte 4 von der Doppelkette 3 übernommen. Hierzu ist die Transportgeschwindigkeit der Doppelkette 3 etwas grösser als diejenige der Sammelkette 2 und der Abstand C zwischen benachbarten Mitnehmern 9 ist etwas grösser als der Abstand B zwischen benachbarten Mitnehmern 5. Die grössere Transportgeschwindigkeit der Doppelkette 3 ergibt sich durch den kleineren Radius des Kettenrades 6 verglichen mit dem Radius des Kettenrades 7. Im Uebergabebereich A werden somit die Druckprodukte 4 jeweils durch einen Mitnehmer 9 der Doppelkette 3 von einem anliegenden Mitnehmer 5 der Sammelkette 2 in Transportrichtung weggeschoben. Nach dem Kettenrad 6 werden die Druckprodukte 4 somit allein von der Doppelkette 3 transportiert. Auf der Doppelkette 3 können dann die Druckprodukte 4 geheftet oder sonstwie weiterverarbeitet werden. Wesentlich ist, dass die Mitnehmer 5 auf dem Kettenrad 6 dann nach unten wegschwenken, wenn sie ganz oder teilweise in der Doppelkette 3 untergetaucht sind.The collecting chain 2 travels in a transfer area A. the double chain 3 and runs after this area A around that Sprocket 6. Here, the collecting chain 2 is in front of the sprocket 7 on a guide rail 14 and after the chain wheel 6 on a Guide rail 15 out. Between the two sprockets 6 and 7 the active strand 2a of the collecting chain 2 is immersed in the double chain 3. The drivers 5 are in the range of Sprocket 7 at the top of the double chain 3 completely protrudes and completely or partially submerged in the area of the sprocket 6. In the transfer area A, the printed products 4 from the double chain 3 adopted. This is the transport speed the double chain 3 is slightly larger than that the collecting chain 2 and the distance C between adjacent drivers 9 is slightly larger than the distance B between neighboring ones Carriers 5. The greater transport speed of the Double chain 3 results from the smaller radius of the chain wheel 6 compared to the radius of the sprocket 7. Im Transfer area A are thus the printed products 4 in each case by a driver 9 of the double chain 3 of an adjacent Carrier 5 of the collection chain 2 pushed away in the transport direction. After the sprocket 6, the printed products 4 thus transported by the double chain 3 alone. On the double chain 3, the printed products 4 can then be stapled or otherwise processed further. It is essential that the Then pivot driver 5 on chain wheel 6 downwards, if they are completely or partially submerged in the double chain 3 are.

Die Figur 2 zeigt das Kettenrad 7, das um eine Achse 10 drehbar gelagert ist und die Doppelkette 3 umlenkt. Diese Doppelkette 3 weist zwei parallel und im Abstand zueinander verlaufende Gelenkketten 12 auf, an denen Auflageelemente 31 befestigt sind, von denen die einen jeweils einen Flügel 9a aufweisen. Zwei gegenüberliegende Flügel 9a bilden einen Mitnehmer 9. Zwischen den beiden Mitnehmerflügeln 9a eines Mitnehmers 9 und auch zwischen den Auflageelementen 31 besteht eine Lücke 32, die knapp so breit ist, dass die Sammelkette 2 einfahren kann. Wesentlich ist nun, dass die Sammelkette 2 vergleichsweise schmal ausgebildet ist und damit entsprechend auch die Lücke 32 vergleichsweise schmal ist. Die Breite D der Sammelkette 2 beträgt etwa 20 mm und ist vorzugsweise schmaler als 30 mm. Die Doppelkette 3 eignet sich deshalb auch zur Aufnahme von vergleichsweise kleinformatigen Druckprodukten. Die Gliederkette 1 der Sammelkette 2 ist eine Kette in der Art einer Fahrradkette und weist seitlich vorstehende Bolzen 21 auf, an denen Elemente 19 und 20 befestigt sind. Die Elemente 19 und 20 sind vorzugsweise U-förmige Kunststoffteile, die zur Aufnahme von jeweils zwei Bolzen 21 Bohrungen 22 besitzen. Die zwei Schenkel 20a der Elemente 19 und 20 sind gemäss Figur 8 im Bereich des aktiven Trums 2a auf einem Kamm 14a der Führungsschiene 14 geführt. Die Elemente 20 unterscheiden sich von den Elementen 19 lediglich durch einen daran befestigten Mitnehmer 5. Dieser Mitnehmer ist in der Ausführung gemäss Figur 3 winklig ausgebildet und besitzt einen Fussteil 5b und einen Kopfteil 5a. Im aktiven Trum 2a gemäss Figur 3 erstreckt sich der Fussteil 5b vertikal, während der Kopfteil 5a in der Laufrichtung gemäss Pfeil 25 nach vorne geneigt ist. Der Kopfteil 5a kann gemäss Figur 7 mit einem Gelenk 34 am Fussteil 5b angebracht sein und lässt sich damit in seiner Neigung verstellen. Die Wirkungsweise der Mitnehmer 5 wird anhand der Figuren 3 und 4 nachfolgend näher erläutert.Figure 2 shows the sprocket 7, which is rotatable about an axis 10 is stored and deflects the double chain 3. This double chain 3 has two parallel and spaced from each other Articulated chains 12 on which support elements 31 are attached are, of which each have a wing 9a. Two opposite wings 9a form a driver 9. Between the two driver wings 9a of a driver 9 and also between the support elements 31 Gap 32, which is just as wide that the collection chain 2 enters can. It is now essential that the collection chain 2 is comparatively is narrow and accordingly the gap 32 is also comparatively narrow. The width D of the Collection chain 2 is about 20 mm and is preferably narrower than 30 mm. The double chain 3 is therefore also suitable for inclusion of comparatively small format print products. The Link chain 1 of the collection chain 2 is a chain of the type a bicycle chain and has laterally projecting bolts 21 on which elements 19 and 20 are attached. The Elements 19 and 20 are preferably U-shaped plastic parts for Hold two bolts 21 each have holes 22. The two legs 20a of the elements 19 and 20 are according to FIG. 8 in the area of the active run 2a on a comb 14a of the guide rail 14 out. The elements 20 differ of the elements 19 only by one attached to it Driver 5. This driver is designed in accordance with Figure 3 is angular and has a foot part 5b and a head part 5a. In the active strand 2a according to Figure 3 extends the foot part 5b vertically, while the head part 5a in the Direction of travel is inclined forward according to arrow 25. The headboard 5a can according to FIG. 7 with a joint 34 on the foot part 5b attached and can be adjusted in its inclination. The operation of the driver 5 is based on the Figures 3 and 4 explained in more detail below.

Die Sammelkette 2 bewegt sich kontinuierlich in Richtung des Pfeils 25. Der Bogen 4 wird in Richtung des Pfeils 26 vertikal auf die Sammelkette 2 abgelegt. Die relative Bewegung und Geschwindigkeit ist durch den Pfeil 27 angegeben. Beim Ablegen des Bogens 4 auf die Sammelkette 2 kann es vorkommen, dass der Bogen 4 in Richtung des Pfeils 28 sich von der Sammelkette 2 abhebt. Die hintere Kante 4b schlägt hierbei am Mitnehmer 5 an. Ist der Mitnehmer 5 gemäss Figur 4 gestreckt und vertikal von der Sammelkette 2 abstehend, so wird der Druckbogen 4 in Richtung des Pfeils nach oben und vorne abgelenkt und kann hierbei von der Sammelkette 2 abspringen. Ist nun der Mitnehmer 5 gemäss Figur 3 geneigt ausgebildet, so wird der Druckbogen in Richtung des Pfeils 35 wieder nach unten auf die Sammelkette 3 zurückgeworfen. Ein Abspringen des Druckproduktes 4 ist damit vermieden. Eine Verbesserung dieses Effektes kann durch eine rauhe Oberfläche des Mitnehmers 5 oder durch eine reibungsvermindernde oder dämpfende Materialwahl, beispielsweise eine rauhe Oberfläche oder gummielastische Bereiche, erreicht werden. Der aufgelegte Druckbogen 4 sitzt rittlings auf der Sammelkette 2 und wird im Falz 4a durch einen Kamm 2a zentriert. Unterhalb der Sammelkette 2 sind die Druckprodukte 4 durch Leitbleche 13 geführt, die gemäss Figur 2 an einer vertikal sich erstreckenden Haltewand 16 angebracht sind. Diese Haltewand 16 ist mit Schrauben 17 an einer Halterung 18 befestigt. Die Figuren 5 und 6 zeigen zwei Mitnehmer 23 und 24 nach ebenfalls möglichen Varianten. Ebenfalls ist hier das obere Ende 23a bzw. 24a in Laufrichtung geneigt. Denkbar ist jedoch auch eine Ausführung, bei welcher die Mitnehmer gemäss Figur 4 gestreckt und damit im aktiven Trum 2a genau vertikal nach oben vorstehend sind.The collection chain 2 moves continuously in the direction of Arrow 25. The bow 4 becomes vertical in the direction of arrow 26 placed on the collection chain 2. The relative movement and speed is indicated by arrow 27. When dropping of the sheet 4 on the collecting chain 2, it can happen that the Bow 4 in the direction of arrow 28 from the collecting chain 2 takes off. The rear edge 4b strikes the driver 5 on. Is the driver 5 stretched and vertical according to Figure 4 protruding from the collecting chain 2, the printed sheet 4 in Direction of the arrow deflected up and forward and can jump off the collection chain 2. Now is the driver 5 inclined according to Figure 3, so the printing sheet down in the direction of arrow 35 onto the collecting chain 3 thrown back. A jumping off of the printed product 4 is avoided. This effect can be improved through a rough surface of the driver 5 or through a friction-reducing or damping material choice, for example a rough surface or rubber-elastic areas, can be achieved. The printed sheet 4 sits astride on the collecting chain 2 and is in the fold 4a by a comb 2a centered. The printed products are below the collecting chain 2 4 guided through baffles 13, which according to FIG vertically extending retaining wall 16 are attached.
