Description

Die Erfindung betrifft eine Einrichtung zum taktweisen Fördern von einer Entnahmestelle mittels Fördervorrichtung etwa senkrecht und in Abständen zugeführten Druckprodukten wie Zeitungen, Zeitschriften oder dgl. (s.z.B. EP-A-0 499 691).The invention relates to a device for the cyclical conveying from a removal point by means of a conveying device approximately vertically and at intervals printed products such as newspapers, magazines or the like (see e.g. EP-A-0 499 691).

Solche Zuführeinrichtungen werden u.a. zur Beschickung von Stapeleinrichtungen angewendet und gestatten u.a. die Übernahme der an der Entnahmestelle anfallenden Gesamtmenge oder einer Teilmenge der Druckprodukte durch selektives Trennen. Diese Einrichtungen sind mit dem Nachteil behaftet, dass die Übergabe der Druckprodukte an der Entnahmestelle zwischen Transporteur und Weiterförderorgan nicht störungsfrei erfolgt, zumal die Druckbogen mit relativ hoher Geschwindigkeit von einem Förderorgan an das folgende übergeben werden.Such feeders are used inter alia. used for loading stacking devices and allow the takeover of the total quantity or a partial quantity of the printed products at the removal point by selective separation. The disadvantage of these devices is that the transfer of the printed products at the point of removal between the transporter and the conveying member does not take place without problems, especially since the printed sheets are transferred from one conveying member to the next at a relatively high speed.

Aufgabe der vorliegenden Erfindung ist es somit, eine Einrichtung der eingangs genannten Art so auszubilden, dass deren beteiligte Förderorgane ein präzises bzw. zuverlässiges Zusammenwirken gewährleisten.The object of the present invention is therefore to design a device of the type mentioned at the outset in such a way that its involved conveying bodies ensure precise or reliable interaction.

Erfindungsgemäss wird diese Aufgabe nach den Merkmalen des kennzeichnenden Teils des Patentanspruches 1 gelöst.
Durch diese konstruktiven Mittel können die Druckprodukte in einem kontinuierlichen Förderfluss von der Fördervorrichtung, bspw. einem Transporteur auf einfache Weise einer nächsten Verarbeitungsstation zugeführt werden.
Die Druckprodukte werden auf ihrem Weg von der Entnahmestelle bis zum Verlassen der Einrichtung weitgehend schlupffrei geführt.This object is achieved according to the features of the characterizing part of patent claim 1.
By means of these constructional means, the printed products can be fed in a continuous conveying flow from the conveying device, for example a conveyor, to a next processing station in a simple manner.
The printed products are largely slip-free on their way from the point of withdrawal to the point of exiting the facility.

Die Greifzangen werden während ihrer kreisenden Bewegung zwangsgesteuert in eine Offenstellung versetzt, die spätestens an der Entnahmestelle erfolgt, und hier, nachdem das Druckprodukt in die Greifzange eingetaucht ist, plötzlich geschlossen. Die Greifzange schwenkt mit dem erfassten Ende des Druckproduktes in eine Ausnehmung am Umfang der Nabe zurück und verharrt dort solange, bis sie die Friktionsstelle zwischen Nabe und Friktionsrad verlassen hat und in den zur Freigabe des Druckproduktes bestimmten Raum, in dem sie sich zwangsgesteuert öffnet, eintaucht. Während dem Öffnen löst sich das zuvor eingespannte Ende des Druckproduktes, welches bedarfsfalls anschliessend von dem nachlaufenden Zangenteil in die Richtung seines Weitertransportes versetzt wird. Der zur Freigabe der Druckprodukte vorgesehene Raum wird zum stromabwärts gerichteten Ende hin durch gleichsinnig angetriebene Fördermittel begrenzt, bspw. durch eine Umlenkrolle und an diese verlaufende endlose Antriebsbänder.The gripping tongs are positively controlled during their circular movement into an open position, which takes place at the removal point at the latest, and here, after the printed product is immersed in the gripping tongs, suddenly closes. With the gripped end of the printed product, the gripper pivots back into a recess on the circumference of the hub and remains there until it has left the friction point between the hub and the friction wheel and plunges into the space intended for releasing the printed product, in which it opens in a positively controlled manner . During opening, the previously clamped end of the printed product is released, which is then, if necessary, displaced by the trailing pliers part in the direction of its further transport. The space provided for releasing the printed products is limited towards the downstream end by conveying means driven in the same direction, for example by a deflection roller and endless drive belts running thereon.

Um eine sichere Zuführung der Druckprodukte gewährleisten zu können, ist es vorteilhaft, wenn die Fördervorrichtung im Bereich der Entnahmestelle etwa prallel zur Tangente an den Umfang der Nabe verläuft.In order to be able to ensure a reliable supply of the printed products, it is advantageous if the conveying device in the region of the removal point runs approximately parallel to the tangent to the circumference of the hub.

Zweckmässigerweise ist unterhalb der Fördervorrichtung eine die Druckbogen in die Lage ihrer Entnahme ausrichtende Mitnehmervorrichtung angeordnet, durch die eine Regelmässigkeit und damit die erforderliche Zuverlässigkeit hinsichtlich Zuführung erreicht werden kann.Appropriately there is a below the conveyor the printed sheets are arranged in the position of their removal-aligning driver device, through which a regularity and thus the required reliability with regard to feeding can be achieved.

Diese Mitnehmervorrichtung ist zur einheitlichen Taktübertragung mit der Nabe antriebsverbunden.This driver device is drive-connected to the hub for uniform clock transmission.

Ebenso sind die Fördervorrichtung und die Nabe taktsynchron verbunden.The conveyor and the hub are also connected in isochronous fashion.

Zur selektiven Entnahme von Druckprodukten besitzt die Fördervorrichtung eine Führungsbahn, die über der Entnahmestelle einen sich nach oben verlagernden Abschnitt aufweist, wodurch die zugeführten Druckprodukte in weiterbildender Ausgestaltung die vorliegende Einrichtung in einer wählbaren Formation verlassen können.
Um zwischen Nabe und Friktionsrad eine optimale Förderwirkung erzielen zu können, sind die Greifzangen vorteilhaft in am Umfang der Nabe angeordneten Ausnehmungen versenkbar ausgebildet, wobei hierzu ein zwangsgesteuerter Bewegungsmechanismus dienen kann wie bspw. ein Verzahnungs-, Kurven- oder Hebelantrieb.For the selective removal of printed products, the conveying device has a guideway which has an upwardly displacing section above the removal point, as a result of which the supplied printed products in a further development can leave the present device in a selectable formation.
In order to be able to achieve an optimal conveying effect between the hub and the friction wheel, the gripping tongs are advantageously designed to be retractable in recesses arranged on the circumference of the hub, wherein a positively controlled movement mechanism such as a toothing, curve or lever drive can serve this purpose.

Vorteilhaft ist das nachlaufende Zangenteil als auf das in dem Raum von der Greifzange gelöste Druckprodukt abweisend einwirkend ausgebildet, sodass letzteres am Ende des Raumes zum Weitertransport erfasst werden kann.The trailing pliers part is advantageously designed to act in a manner that repels the printed product released from the gripping pliers in the space, so that the latter can be gripped at the end of the space for further transport.

Zweckmässigerweise ist der Abstand zwischen der Nabe und dem Friktionsrad einstellbar ausgebildet, d.h. zur Optimierung des Druckbogentransportes soll der Abstand auch wegen der unterschiedlichen Dicke der Druckprodukte verstellt werden können.The distance between the hub and the friction wheel is expediently designed to be adjustable, ie in order to optimize the transport of the printed sheets, the distance should also be adjustable because of the different thickness of the printed products.

Mit Hilfe einer vorzugsweise auf das Friktionsrad einwirkenden Federkraft kann dieser verstellbare Abstand weiter optimiert werden.This adjustable distance can be further optimized with the aid of a spring force that preferably acts on the friction wheel.

Den Fördereffekt kann ein Gummi- oder ähnlicher Belag am Umfang des Friktionsrades begünstigen.A rubber or similar covering on the circumference of the friction wheel can promote the conveying effect.

Durch eine Umlenkrolle und wenigstens ein endloses Antriebsband, welches mit ersterer gemeinsam angetrieben ist, kann dem Raum durch die Bildung eines Einzugsspaltes in Richtung stromabwärts gerichtet eine Förderwirkung vermittelt werden.By means of a deflection roller and at least one endless drive belt, which is driven together with the former, a conveying effect can be imparted to the room by forming a feed gap in the direction downstream.

Der Raum ist ausserdem ausschliesslich durch gleichsinnig angetriebene Elemente ausgebildet.The room is also exclusively formed by elements driven in the same direction.

Als zusätzliche Führungsunterstützung der Druckprodukte im Bereich der Verbindung zwischen Umlenkrolle und Antriebsband/Antriebsbändern kann ein anliegendes endloses Führungsband verwendet werden.An additional endless guide belt can be used as additional guide support for the printed products in the area of the connection between the deflection roller and drive belt / drive belts.

Anschliessend wird die erfindungsgemässe Einrichtung anhand eines in einer einzigen Figur dargestellten Ausführungsbeispiels näher erörtert.The device according to the invention is then discussed in more detail using an exemplary embodiment shown in a single figure.

Nachfolgend wird die erfindungsgemässe Einrichtung anhand eines in der einzigen Figur der Zeichnung dargestellten Ausführungsbeispiels näher beschrieben.The device according to the invention is described in more detail below with reference to an embodiment shown in the single figure of the drawing.

Mit 1 ist eine Einrichtung zum taktweisen Fördern von einer Entnahmestelle 2 mittels einer Fördervorrichtung 3, bspw. eines mit Halteklammern 4 ausgebildeten Transporteurs etwa in senkrechter Lage und in Abständen zugeführten Druckprodukten 5 wie Zeitungen, Zeitschriften oder dgl. veranschaulicht.
Die zugeführten Druckprodukte 5 sind üblicherweise gefalzt und mit ihrer offenen Seite in der Halteklammer 4 eingespannt.
Auf ihrem Weg zur Entnahmestelle 2 werden die Druckprodukte 5 vor der Entnahme aus den etwa parallel zu einer horizontalen Tangente an den Umfang einer Nabe 10 geführten Halteklammern 4 über eine Stabilisiervorrichtung 6 geführt, wo sie hinsichtlich ihrer Lage beruhigt werden.
Dieser Vorgang kann durch an einem endlosen Zugorgan 7 befestigten Mitnehmern 8 erfolgen, welche an der Rückseite der an einer zur Entnahmestelle hin geneigten Führungsschiene 16 anstehenden Druckprodukte 5 in Anlage gebracht werden und so eine stabilisierende Wirkung auf diese ausüben.1 shows a device for the cyclical conveying of a removal point 2 by means of a conveying device 3, for example a conveyor designed with holding clamps 4, approximately in a vertical position and at intervals from printed products 5 such as newspapers, magazines or the like.
The supplied printed products 5 are usually folded and clamped with its open side in the retaining clip 4.
On their way to the removal point 2, the printed products 5 are guided via a stabilizing device 6 before being removed from the holding clamps 4, which are guided approximately parallel to a horizontal tangent to the circumference of a hub 10, where they are calmed in terms of their position.
This process can be carried out by means of drivers 8 fastened to an endless traction element 7, which are brought into abutment on the rear side of the printed products 5 which are in contact with a guide rail 16 inclined towards the removal point and thus exert a stabilizing effect on them.

Zu diesem Zweck weisen die Mitnehmer 8 jeweils einen grösseren Abstand zueinander und eine höhere Fortbewegungsgeschwindigkeit als die zugeführten Druckprodukte auf.For this purpose, the drivers 8 are each at a greater distance from one another and at a higher travel speed than the supplied printed products.

Selbstverständlich sind Nabe 10 und Fördervorrichtung 3 taktgleich gekoppelt.Of course, hub 10 and conveyor device 3 are coupled in synchronism.

An der durch eine strichpunktierte Linie 17 angedeuteten Führungsbahn der Fördervorrichtung 3 kann über der Entnahmestelle 2 eine selektive Trennung (Teilentnahme) der zugeführten Druckprodukte 5 erfolgen.On the guide path of the conveying device 3 indicated by a dash-dotted line 17, a selective separation (partial removal) of the printed products 5 supplied can take place via the removal point 2.

Die Greifzangen 11 sind in geschlossenem Zustand, d.h. nach Erfassen eines Druckproduktes 5 von dem Umfang der Nabe 10 nach innen zurückversetzt gesteuert, sodass Nabe 10 und Umlenkrolle 14 gleichmässig abrollen können, ohne die Druckprodukte 5 zu beschädigen.
Die Greifzangen 11 sind hierzu schwenkbar ausgebildet und lassen sich in Ausnehmungen 18 versenken.The gripping tongs 11 are controlled in the closed state, ie after a printed product 5 has been gripped back inwards from the periphery of the hub 10, so that the hub 10 and deflection roller 14 can roll evenly without damaging the printed products 5.
For this purpose, the gripping tongs 11 are designed to be pivotable and can be sunk into recesses 18.

Dadurch wird das Erfassen der Druckprodukte 5 bspw. an der gefalzten Kante 9 begünstigt, wozu wenigstens eine mit der angetriebenen Nabe 10 verbundene Greifzange 11 vorgesehen ist. Diese Greifzangen 11 sind nach dem Erfassen der Druckprodukte 5 hinter den Umfang der Nabe 10 versetzbar gesteuert, sodass letztere mit einem der Entnahmestelle nachgeschalteten Friktionsrad 12 eine Förderwirkung auf die Druckprodukte 5 erzeugt.
Anschliessend durchsetzen die Druckprodukte 5 etwa in senkrechter Richtung einen freien Raum 13, der durch mehrere Antriebselemente gebildet wird, wobei der Mündungsbereich des Raumes 13 durch die Nabe 10 sowie das Friktionsrad 12 und ein Einzugsspalt am Förderende des Raumes 13 durch eine Umlenkrolle 14 und ein diese teilweise umschlingendes endloses Antriebsband 22 begrenzt ist.This favors the detection of the printed products 5, for example on the folded edge 9, for which purpose at least one with the driven hub 10 connected gripper 11 is provided. After gripping the printed products 5, these gripping tongs 11 are displaceably controlled behind the circumference of the hub 10, so that the latter produces a conveying effect on the printed products 5 with a friction wheel 12 connected downstream of the removal point.
The printed products 5 then pass through a free space 13, approximately in the vertical direction, which is formed by a plurality of drive elements, the mouth region of the space 13 through the hub 10 and the friction wheel 12 and a feed gap at the conveying end of the space 13 through a deflection roller 14 and one partially wrapping endless drive belt 22 is limited.

Die Anwendung und Ausbildung von Greifzangen für die Entnahme und den Transport von Druckprodukten sind hinreichend bekannt, sodass eine entsprechende Konstruktionsbeschreibung nicht erforderlich ist.The use and design of gripping tongs for the removal and transport of printed products are well known, so that a corresponding design description is not necessary.

Aufgrund der unterschiedlichen Dicke der Druckprodukte und zur Erzeugung eines Reibungsdruckes ist der Abstand zwischen Nabe 10 und Friktionsrad 12 verstell- bzw. einstellbar ausgebildet.Due to the different thickness of the printed products and to generate a friction pressure, the distance between the hub 10 and the friction wheel 12 is designed to be adjustable or adjustable.

Mittels eines nichtgezeigten Kraftspeichers kann das Friktionsrad nachgiebig an die Nabe 10 gepresst werden.The friction wheel can be resiliently pressed against the hub 10 by means of a force accumulator (not shown).

Der nachlaufende Zangenteil 26 einer Greifzange 11 am Umfang der Nabe 10 übernimmt die zusätzliche Aufgabe, die vordere Kante des soeben abgegebenen Druckproduktes 5 in die Förderrichtung abzustossen.The trailing pliers part 26 of a gripper 11 on the circumference of the hub 10 takes on the additional task of pushing off the front edge of the printed product 5 just dispensed in the conveying direction.

Die Nabe 10 und das Friktionsrad 12 bilden einen zur Entnahmestelle 2 hin offenen Einzugsspalt 19, der durch eine zum Umfang der Nabe 10 beabstandete Leitfläche 20 eine Führungsanordnung bildet.The hub 10 and the friction wheel 12 form an intake gap 19 which is open towards the removal point 2 and which has a guide arrangement through a guide surface 20 which is spaced apart from the circumference of the hub 10 forms.

Das stromabwärts gerichtete Ende des Raumes 13 weist einen Einzugsspalt 21 auf, der durch die Umlenkrolle 14 und wenigstens ein diese teilweise umschlingendes Antriebsband 22 geformt wird.The downstream end of the space 13 has a feed gap 21 which is formed by the deflection roller 14 and at least one drive belt 22 which partially wraps around it.

Bei Verwendung von zwei parallel geführten Antriebsbändern 22 ist es möglich, - wie in der einzigen Figur dargestellt -, dass im Umlenkbereich an der Umlenkrolle 14 ein anliegendes Führungsband 23 dazwischen vorgesehen ist.When using two drive belts 22 guided in parallel, it is possible, as shown in the single figure, for an adjacent guide belt 23 to be provided in between in the deflection area on the deflection roller 14.

Die Druckprodukte 5 verlassen in geschuppter Form den Umlenkbereich an der Umlenkrolle 14 und können nach oder vor letzterer durch eine Umschuppvorrichtung 24 umgeschichtet werden.The printed products 5 leave the deflection area on the deflection roller 14 in shingled form and can be shifted after or before the latter by means of a shifting device 24.

Selbstverständlich ist auch eine Vereinzelungsformation der Druckprodukte 5 möglich, die sowohl an der Entnahmestelle 2 wie auch nach der Umlenkrolle 14 vorgenommen werden könnte.Of course, a separation formation of the printed products 5 is also possible, which could be carried out both at the removal point 2 and after the deflection roller 14.

An die Umlenkrolle 14 schliesst im vorliegenden Ausführungsbeispiel ein Stapelbildner 25 an, der zur Aufnahme der Druckprodukte 5 vorgesehen ist.In the present exemplary embodiment, a stack former 25, which is provided for receiving the printed products 5, adjoins the deflection roller 14.
