Fig. 1 zeigt eine Seitenansicht einer erfindungsgemässen Vorrichtung, die zum Transport von flexiblen, flächigen Erzeugnissen 1, insbesondere Druckereierzeugnissen, von einem an einer Aufnahmestelle positionierten Stapel 2 zu einer Abgabestelle dient. Die Vorrichtung weist ein Separierorgan 40 sowie drei Stützelemente 3x, 3y, 3z und drei Halteorgane 4x, 4y, 4z auf, die, angetrieben von einer Welle 5, in einer ersten bzw. in einer zweiten Bahn B1; B2 in derselben vorzugsweise konstanten Winkelgeschwindigkeit um die Achse der Welle 5 geführt sind und vereinzelte Erzeugnisse 1b, 1c, 1d transportieren und stützen. Durch die Welle 5 wird ein Umlaufrad 52 angetrieben, an dem die Halteorgane 4x, 4y, 4z umfangsseitig in gleichen Abständen voneinander befestigt sind.Fig. 1 shows a side view of an inventive Device for the transport of flexible, flat Products 1, in particular printed matter, from to a stack 2 positioned at a receiving point serves a delivery point. The device has one Separator 40 and three support elements 3x, 3y, 3z and three holding members 4x, 4y, 4z, which, driven by a shaft 5, in a first or in a second path B1; B2 in the same preferably constant Angular velocity guided around the axis of the shaft 5 and transport individual products 1b, 1c, 1d and support. An orbital gear 52 is formed by the shaft 5 driven, on which the holding members 4x, 4y, 4z attached circumferentially at equal distances from each other are.

Die zu transportierenden Erzeugnisse 1, die in einem Stapel 2 gelagert sind, sind an der bezüglich der Drehrichtung des Umlaufrades 52 und somit der Umlaufrichtung der Stütz- und Halteorgane 3x, 3y, 3z bzw. 4x, 4y, 4z vorlaufenden ersten Kante 11 kraftschlüssig gehalten und werden im Randbereich der bezüglich der Drehrichtung des Umlaufrades 52 nachlaufenden zweiten Kante 12 durch das in einer dritten Bahn B3 geführte Separierorgan 40 einzeln erfasst und angehoben. Zum kraftschlüssigen Halten der Erzeugnisse 1 an der ersten Kante 11 kann, wie in Fig. 1 gezeigt, ein Haltebügel 15 und/oder ein Haftmittel (wie beispielsweise "post-it"®) vorgesehen sein, durch das die Randbereiche oder die Stirnseiten der ersten Kanten 11 miteinander verbunden sind.The products to be transported 1, which in a Stack 2 are stored on the in terms of Direction of rotation of the planet gear 52 and thus the Direction of rotation of the support and holding members 3x, 3y, 3z or 4x, 4y, 4z leading first edge 11 non-positively held and are in the marginal area of the Direction of rotation of the planet gear 52 trailing second Edge 12 through the guided in a third path B3 Separator 40 individually detected and raised. To the frictionally holding the products 1 at the first As shown in FIG. 1, edge 11 can have a holding bracket 15 and / or an adhesive (such as "post-it" ®) be provided through which the edge areas or End faces of the first edges 11 connected to each other are.

Das in der dritten Bahn B3 geführte Separierorgan 40 ist zum Ansaugen oder Ergreifen der gestapelten Erzeugnisse 1; 1a im frei liegenden Randbereich der zweiten Kante 12 geeignet. Die dritte Bahn B3 verläuft dabei derart, dass die zweite Kante 12 eines Erzeugnisses 1 mit gegen die Welle 5 gewandter Oberseite 13 in den Bereich der ersten Bahn B1, in der die Stützelemente 3x, 3y, 3z geführt sind, angehoben werden kann.The separating member 40 guided in the third path B3 is for sucking or gripping the stacked products 1; 1a in the exposed edge area of the second edge 12 suitable. The third path B3 runs in such a way that the second edge 12 of a product 1 with against Wave 5 facing top 13 in the area of the first Path B1, in which the support elements 3x, 3y, 3z are guided, can be raised.

Damit beim Anheben der Erzeugnisse 1 kein Zug auf die Verbindungsstelle ausgeübt wird, verläuft die dritte Bahn B3 in dem Bereich, in dem das Separierorgan 40 das Erzeugnis 1 festhält, vorzugsweise entlang einem Segment eines Kreises, dessen Mittelpunkt im Bereich der Verbindungsstelle des obersten Erzeugnisses 1a des Stapels 2 liegt.So that when lifting the products 1 no train on the The third lane runs B3 in the area in which the separating member 40 the Product 1 holds, preferably along a segment of a circle, the center of which is in the area of Junction of the top product 1a of the stack 2 lies.

Die erste Bahn B1, in der die Stützelemente 3x, 3y, 3z geführt sind, und die zweite Bahn B2, in der die Halteorgane 4x, 4y, 4z geführt sind, verlaufen derart, dass, wie nachstehend anhand von Fig. 2 noch im Detail beschrieben, vom Separierorgan 40 angehobene Erzeugnisse 1 durch ein Stützelement 3 unterlaufen, mit der Unterseite 14 gegen die Welle 5 gewandt tangential zur zweiten Bahn B2 ausgerichtet und dort von einem Halteorgan 4 an der Unterseite 14 erfasst, vom Stapel 2 gelöst, zur Abgabestelle befördert und dort abgegeben werden können. Nach Abschluss des Transportvorgangs läuft daher die in Drehrichtung des Umlaufrades 52 ursprünglich nachlaufende Kante 12 des Erzeugnisses 1 vor.The first path B1, in which the support elements 3x, 3y, 3z are guided, and the second path B2, in which the Holding members 4x, 4y, 4z are guided, run in such a way that, as detailed below with reference to FIG. 2 described, products raised by the separator 40 1 undermine by a support element 3, with the underside 14 facing the shaft 5 tangential to the second path B2 aligned and there by a holding member 4 on the Bottom 14 captured, detached from the stack 2 for Delivery point can be transported and handed over there. After the transport process is complete, the in Direction of rotation of the planet gear 52 originally trailing Edge 12 of the product 1 before.

An der Abgabestelle werden die Erzeugnisse 1 von den Halteorganen 4x, 4y, 4z bis zu einer Ablage 6 befördert und dort freigegeben, so dass sie von einem weiteren Förderorgan, vorzugsweise einer Transportklammer 7, beispielsweise bei der nachlaufenden ersten Kante 11 ergriffen und entlang einer vierten Bahn B4 weiterbefördert werden können. Die Ablage 6 weist vorzugsweise eine Rampe auf, durch die von den Halteorganen 4x, 4y, 4z transportierte und freigegebene Erzeugnisse 1 jeweils in derselben Position gehalten und vorzugsweise zusätzlich durch zugeordnete Stützelemente 3 gestützt werden, so dass sie von den Transportklammern 7 stets sicher erfasst werden können.At the delivery point, the products 1 from the Holding organs 4x, 4y, 4z transported to a shelf 6 and released there so that they can from another Conveyor, preferably a transport clamp 7, for example with the trailing first edge 11 seized and along a fourth path B4 can be carried on. The tray 6 points preferably a ramp through which the Holding organs 4x, 4y, 4z transported and released Products 1 each held in the same position and preferably additionally by assigned support elements 3 are supported so that they are supported by the transport clamps 7 can always be recorded safely.

Die Übergabe an der Abgabestelle kann auch an andersartige Förderer erfolgen. In einer vorzugsweisen Ausgestaltung der Erfindung sind die Erzeugnisse 1 von den Halteorganen 4 an der Abgabestelle, wie in Fig. 3 gezeigt, in einen Förderspalt 89 eines Bandförderers einführbar, der zwei um Umlenkrollen 81 bzw. 91 und 92 geführte Förderbänder 8, 9 aufweist.The handover at the delivery point can also be made to other types Sponsors take place. In a preferred embodiment the invention are the products 1 of the holding members 4 at the delivery point, as shown in Fig. 3, in a Conveyor gap 89 of a belt conveyor insertable, the two around Deflection rollers 81 or 91 and 92 guided conveyor belts 8, 9 having.

Das in den Förderspalt 89 eingeführte Erzeugnis 1 wird beschleunigt wegtransportiert, um eine Kollision mit dem nachfolgenden Stützelement 3y zu vermeiden. Zur Vermeidung einer solchen Kollision ist es auch denkbar, statt das vom Bandförderer erfasste Erzeugnis 1 zu beschleunigen, das nachfolgende Stützelement 3y zu verzögern oder gesteuert gegen innen zur Bewegungsbahn B2 hin zu verdrängen, z.B. auf die in Fig. 1 gezeigte Weise.The product 1 introduced into the conveyor gap 89 becomes accelerated to a collision with the to avoid subsequent support element 3y. To avoid Such a collision is also conceivable instead of that of Belt conveyor to accelerate product 1 that subsequent support element 3y to delay or controlled to displace towards the movement path B2, e.g. in the manner shown in FIG.

Grundsätzlich kann die erste Bahn B1 ebenso wie die zweite Bahn B2 kreisförmig verlaufen. In der in Fig. 1 gezeigten bevorzugten Ausgestaltung verläuft die erste Bahn B1 jedoch derart, dass ein aus der kraftschlüssigen Verbindung gelöstes Erzeugnis 1d durch ein folgendes Stützelement 3 an der Unterseite 14 im Bereich der nun nachlaufenden ersten Kante 11 bis zur Abgabe der Erzeugnisse 1 gestützt wird.Basically, the first path B1 can be the same as the second Lane B2 is circular. In the shown in Fig. 1 preferred embodiment, the first path B1 however, such that one from the non-positive Connection loosened product 1d by a following Support element 3 on the underside 14 in the area of the now trailing first edge 11 until delivery of the Products 1 is supported.

Vorzugsweise verläuft die erste Bahn B1 an der Stelle, an der die Erzeugnisse 1 von den Halteorganen 4x, 4y, 4z erfasst werden und/oder an den Stellen, an denen die Erzeugnisse 1 von den Halteorganen 4x, 4y, 4z freigegeben werden, zumindest annähernd tangential zur zweiten Bahn B2, so dass die Erzeugnisse 1 während der Übernahme- bzw. Übergabevorgänge vorteilhaft ausgerichtet sind.The first path B1 preferably runs at the point of the products 1 from the holding members 4x, 4y, 4z are recorded and / or where the Products 1 released by the holding members 4x, 4y, 4z become, at least approximately tangential to the second path B2, so that the products 1 during the takeover or Transfer processes are advantageously aligned.

Zur Realisierung eines gewünschten Verlaufs der ersten Bahn B1 sind die von der Welle 5 angetriebenen Stützelemente 3x, 3y, 3z beispielsweise in Führungen 51, die im Umlaufrad 52 vorgesehen sind, oder durch ein Gestänge radial verschiebbar gelagert. Die radiale Auslenkung der Stützelemente 3x, 3y, 3z entlang der ersten Bahn B1 wird vorzugsweise mittels einer Kulisse, entlang der die Stützelemente 3x, 3y, 3z, beispielsweise mittels radial nach innen gerichteter Federkraft, geführt werden, in Funktion des Drehwinkels des Umlaufrades 52 festgelegt. Möglich ist ferner die Verwendung von Kurvengetrieben oder Kurvensteuerungen, wie sie aus Dubbel, Taschenbuch für den Maschinenbau, Springer-Verlag, Berlin 1990, 17. Auflage, Seiten G152 - G155 bzw. T38 - T39 bekannt sind.To realize a desired course of the first Path B1 are those driven by shaft 5 Support elements 3x, 3y, 3z, for example in guides 51, which are provided in the planet gear 52, or by a Rods mounted radially displaceable. The radial Deflection of the support elements 3x, 3y, 3z along the first Path B1 is preferably along by means of a backdrop of the support elements 3x, 3y, 3z, for example by means of radially inward spring force, set as a function of the angle of rotation of the planet gear 52. It is also possible to use cam gears or Curve controls, such as those from Dubbel, paperback for the Mechanical engineering, Springer-Verlag, Berlin 1990, 17th edition, Pages G152 - G155 and T38 - T39 are known.

The product 1 will then with the underside 14 against the shaft 5 facing, aligned along the second path B2 (Fig. 2d, Pos. D, Fig. 2a, Pos. E and Fig. 2b, Pos. F).

Das ausgerichtete Erzeugnis 1 (Fig. 1, Erzeugnis 1c) wird nun an der Unterseite 14, im Randbereich der zweiten Kante 12, von einem nachfolgenden Halteorgan 4 erfasst (Fig. 2c, Pos. g und Fig. 2d, Pos. h). In dieser Lage ist das Erzeugnis 1; 1c im Bereich der ersten Kante 12 noch immer kraftschlüssig gehalten. Erst beim Weiterdrehen der Welle 5 wird das Erzeugnis 1; 1c aus der oben beschriebenen kraftschlüssigen Verbindung gelöst (Fig. 2a, Pos. i) und weiterbefördert (Fig. 2b, Pos. j).The aligned product 1 (Fig. 1, product 1c) is now on the underside 14, in the edge region of the second edge 12, captured by a subsequent holding member 4 (Fig. 2c, Item g and Fig. 2d, item h). In this situation it is Product 1; 1c in the area of the first edge 12 still held non-positively. Only when turning the shaft further 5 the product 1; 1c from the one described above non-positive connection released (Fig. 2a, item i) and forwarded (Fig. 2b, item j).

In einer weiteren Phase wird das abgelöste Erzeugnis 1; 1d an der Unterseite 14 im Bereich der nachlaufenden ersten Kante 11 durch das nachfolgende Stützelement 3, welches das nachfolgende Erzeugnis 1 ausrichtet bzw. ausgerichtet hat, vorzugsweise bis zur Abgabe des Erzeugnisses 1 gestützt (Fig. 2c, Pos. k und Fig. 2d, Pos. l).In a further phase, the detached product 1; 1d on the underside 14 in the area of the trailing first Edge 11 through the subsequent support element 3, which aligns or aligns the following product 1 has, preferably until delivery of the product 1 supported (Fig. 2c, Pos. k and Fig. 2d, Pos. l).

Fig. 2a, Pos. m und Fig. 2b, Pos. n zeigen die Übergabe des vom Halteorgan 4 freigegebenen, aber noch immer gestützen Erzeugnisses 1; 1d an die Ablage 6 bzw. die Transportklammer 7.Fig. 2a, item m and Fig. 2b, item n show the transfer the released by the holding member 4, but still supported product 1; 1d to the tray 6 or the Transport clamp 7.

Aus Fig. 2c, Pos. o und Fig. 2d, Pos. p ist der Weitertransport des von der Transportklammer 7 erfassten Erzeugnisses 1; 1d ersichtlich.From Fig. 2c, item o and Fig. 2d, item p is the Further transport of the gripped by the transport clamp 7 Product 1; 1d can be seen.

Die verschiedenen Funktionen, anhand denen ein Erzeugnis 1 zuverlässig vom Stapel 2 abgelöst und zur Abgabestelle transportiert werden kann, können durch einfach aufgebaute Stützelemente, Halte- und Separierorgane 3, 4, 40 in hoher Geschwindigkeit ausgeführt werden, woraus eine hohe Transportkapazität der Vorrichtung resultiert. Die Stützelemente 3x, 3y, 3z, die als Stangen oder Profilstäbe ausgestaltet sein können, benötigen nebst der Führung in der ersten Bahn B1 keine weiteren Steuerungsfunktionen, weshalb ein geringer Herstellungs- und Steuerungsaufwand resultiert. Der Wegfall von Steuerungsfunktion bzw. der vereinfachte Transportablauf unterstützt wiederum die Erhöhung der Transportleistung.The different functions by which a product 1 reliably detached from stack 2 and to the delivery point can be transported by simply constructed Supporting elements, holding and separating elements 3, 4, 40 in high Speed to run, resulting in a high Transport capacity of the device results. The Support elements 3x, 3y, 3z, used as rods or profile bars in addition to the guide in the first lane B1 no further control functions, which is why there is little manufacturing and control effort results. The elimination of the control function or the simplified transport process in turn supports the Increase in transport performance.

Die Halteorgane 4x, 4y, 4z, die als Saugorgane oder Greifer ausgebildet sein können, sind in Abhängigkeit des Drehwinkels der Welle 5 derart steuerbar, dass etwa zwischen den in Fig. 2 gezeigten Positionen h bis l Luft bzw. das betreffende Erzeugnis 1; 1d angesaugt bzw. eine Greiffunktion ausgelöst wird. Der Aufbau und die Steuerung der Halteorgane 4x, 4y, 4z erfolgt daher ebenfalls in einfacher Weise mit geringem Aufwand.The holding organs 4x, 4y, 4z, which act as suction organs or Grippers can be formed depending on the Angle of rotation of the shaft 5 controllable such that between positions h to l of air shown in FIG. 2 or the product in question 1; 1d sucked in or one Gripping function is triggered. The construction and control the holding members 4x, 4y, 4z is therefore also in simple way with little effort.

Das Separierorgan 40 kann ebenfalls als Saugorgan oder Greifer ausgestaltet sein.The separating element 40 can also act as a suction element or Be designed gripper.

Der Antrieb für die Welle 5 und der Antrieb des Separierorgans 40 (sofern ein getrennter Antrieb vorhanden ist) sind vorzugsweise axial in bezug auf die Welle 5 gegeneinander verschoben angeordnet. Der Antrieb für die Welle 5 kann z.B. hinter dem Umlaufrad 52 angeordnet sein (daher in der Zeichnung nicht dargestellt) während der Antrieb des Separierorgans 40 vor dem Umlaufrad 52 angeordnet ist.The drive for shaft 5 and the drive of the Separator 40 (if a separate drive is available is preferably axially with respect to the shaft 5 arranged shifted against each other. The drive for the Wave 5 can e.g. be arranged behind the planet gear 52 (therefore not shown in the drawing) during the Drive of the separator 40 in front of the planet gear 52 is arranged.

Damit die volle Leistung der Vorrichtung ausgeschöpft werden wird, kann die Zahl der verwendeten Stützelemente, Halteorgane und Separierorgane 3, 4, 40 unter Berücksichtigung der Abmessungen und der Masse der zu transportierenden Erzeugnisse 1 optimiert werden. So that the full performance of the device is exhausted the number of supporting elements used, Holding members and separating members 3, 4, 40 under Taking into account the dimensions and mass of the transporting products 1 can be optimized.

Aus Fig. 1 ist ersichtlich, dass auch das Halteorgan 4x und somit auch die weiteren Halteorgane 4y, 4z entlang der dritten Bahn B3 abgesenkt werden könnten. Anstelle des oben beschriebenen Separierorgans 40 könnten daher auch die Halteorgane 4x, 4y, 4z zum Erfassen und Anheben von Erzeugnisse 1 verwendet werden. Für diesen Fall wird der Verlauf der Halteorgane 4x, 4y, 4z in der zweiten Bahn B2 durch eine zusätzliche Auslenkung in der dritten Bahn B3 ergänzt. Durch diese Massnahmen kann auf ein gesondertes Separierorgan 40 verzichtet werden. Diese zusätzliche Funktion der Halteorgane 4x, 4y, 4z, die einen erhöhten Steuerungsaufwand verursacht, begrenzt jedoch die Förderkapazität, da für das Absenken und Anheben relativ viel Zeit benötigt wird. Zudem ergibt sich ein ungünstigerer Verlauf der zweiten Bahn B2.From Fig. 1 it can be seen that the holding member 4x and thus also the other holding members 4y, 4z along the third web B3 could be lowered. Instead of Separator 40 described above could therefore also the holding elements 4x, 4y, 4z for the detection and lifting of Products 1 are used. In this case the Course of the holding members 4x, 4y, 4z in the second track B2 by an additional deflection in the third path B3 added. Through these measures, a separate Separator 40 are dispensed with. This additional Function of the holding organs 4x, 4y, 4z, the increased Control effort causes, but limits Production capacity as relative for lowering and raising a lot of time is needed. There is also a less favorable course of the second track B2.

Die Erzeugnisse 1 sind vorzugsweise leichtere Druckereiprodukte, beispielsweise Zettel in der Art von "post-it"®-Produkten, oder mit einem Inhalt versehene Warenproben.The products 1 are preferably lighter Printed products, for example notes of the type of "post-it" ® products, or with content Product samples.

Die in Fig. 1 - Fig. 3 gezeigten Vorrichtungen sind vorzugsweise Ausgestaltungen der Erfindung, bei denen die Stützelemente 3 und die Halteorgane 4 angetrieben von einer Welle 5 um eine Achse, die Achse der Welle 5, geführt sind. Anstelle eines Wellenantriebs kann auch ein weiterer Antrieb, so z.B. ein Kettenantrieb, verwendet werden, durch den die Stützelemente 3 und die Halteorgane 4 synchron um eine Achse geführt werden.The devices shown in Figures 1-3 are preferably embodiments of the invention, in which the Support elements 3 and the holding members 4 driven by a shaft 5 about an axis, the axis of the shaft 5, are led. Instead of a shaft drive, a additional drive, e.g. a chain drive used through which the support elements 3 and the holding members 4 are guided synchronously around an axis.
