Description

Die Erfindung betrifft eine Vorrichtung nach dem Oberbegriff des Anspruches 1.The invention relates to a device according to the preamble of claim 1.

Derartige bekannte Vorrichtungen bestehen aus zwei Bewegungsgruppen. Die erste wird als Friktionsbaugruppe bezeichnet und besteht aus den Friktionsfördergurten oder -Rädern und feststehenden oder langsam gegenläufig drehenden Rädern, die zusammen eine Produktschleuse bilden, d.h. einen Zuschnitt von dem Produktstapel trennen und der zweiten Bewegungsgruppe, der sogenannten Förderbaugruppe zu fördern. Diese Förderbaugruppe besteht normalerweise aus einem Wellenpaar mit Förderrollen oder Fördergurten. Die Fördergeschwindigkeit dieser Förderbaugruppe ist normalerweise größer als die der Friktionsbaugruppe. Die Förderbaugruppe stellt sicher, daß die Produkte, die innerhalb der Friktionsbaugruppe vom Produktstapel separiert werden, schneller als in der Vorförderung weitergefördert und damit sauber von dem nachfolgenden Produkt getrennt werden. Sowohl der Durchlaß der Produktschleuse als auch der Abstand des Wellenpaares in der Förderbaugruppe müssen auf dem Produkt, insbesondere seiner Dicke, angepaßt werden.Such known devices consist of two movement groups. The first is called the friction assembly and consists of the friction conveyor belts or wheels and fixed or slowly counter rotating wheels, which together form a product lock, i.e. a blank separate from the product stack and the second movement group, to promote the so-called conveyor assembly. This conveyor assembly normally consists of a pair of shafts with conveyor rollers or conveyor belts. The conveyor speed this conveyor assembly is usually larger than that of the friction assembly. The conveyor assembly ensures that the products within the friction assembly be separated from the product stack, faster than promoted in the pre-promotion and thus clean of the following product. Both the culvert the product lock and the distance between the pair of shafts in the conveyor assembly must be on the product, in particular its thickness.

Die Friktionsbaugruppe und die Förderbaugruppe werden durch einen gemeinsamen Antrieb angetrieben. Um die Mitläufigkeit der Wellen der Förderbaugruppe zu erreichen, sind die Wellenpaare gewöhnlich mit zwei Stirnzahnrädern verbunden. Daraus ergibt sich, daß der Abstand der Wellen der Förderbaugruppe sich nur in einem geringen Bereich variieren läßt. Dieser Bereich ist durch den Kraftfluß zwischen den Stirnzahnrädern begrenzt. Stärkere Produkte lassen sich dann nicht mehr zuverlässig fördern.The friction assembly and the conveyor assembly are made by driven a common drive. To keep up To reach the shafts of the conveyor assembly are the shaft pairs usually connected with two spur gears. Out of it it follows that the distance between the shafts of the conveyor assembly can only be varied in a small range. This area is due to the flow of force between the spur gears limited. Stronger products can then be no longer support reliably.

Der Erfindung liegt nun die Aufgabe zugrunde, eine Vorrichtung nach dem Oberbegriff des Anspruches 1 zu schaffen, die zuverlässig Produkte in einem großen dicken Bereich, d.h. insbesondere auch dickere Zuschnitte zuverlässig separiert und fördert.The invention is based on the object of a device to create according to the preamble of claim 1 reliable products in a large thick range, i.e. in particular also reliably cut thicker blanks and promotes.

Diese Aufgabe wird durch das Kennzeichen des Anspruches 1 gelöst.This object is achieved by the characterizing part of claim 1 solved.

Der gemeinsame Antrieb, vorzugsweise ein Elektromotor, treibt bei der Erfindung den endlosen doppelseitigen Zahnriemen an, der die entsprechenden Antriebszahnscheiben auf den verschiedenen Wellen, je nach dem wie die Drehrichtung erwünscht ist, umschlingt. Da die Förderrollen oder -Gurte, die die aus der Produktschleuse austretenden Zuschnitte aufnehmen, mitläufig arbeiten, ist eine entsprechende Umschlingung mit dem doppelseitigen Zahnriemen erforderlich. Die eine Zahnscheibe wird durch die Zähne auf der einen Seite des Zahnriemens und die andere Zahnscheibe durch die Zähne auf der anderen Seite angetrieben. Die Abstände der Gurte oder Räder lassen sich in einem großen Bereich zur Anpassung auch an dicke Produkte verändern. Eine Spannvorrichtung (Anspruch 2) sorgt dafür, daß der Zahnriemen immer richtig gespannt ist um für einen exakten formschlüssigen Antrieb und Umlauf zu sorgen. The common drive, preferably an electric motor, drives the endless double-sided toothed belt in the invention on the corresponding drive pulleys the different shafts, depending on how the direction of rotation is desired. Because the conveyor rollers or belts, which receive the blanks emerging from the product lock, working co-operatively is a corresponding wrap required with the double-sided toothed belt. The one Tooth washer is through the teeth on one side of the Timing belt and the other pulley through the teeth driven on the other side. The distances of the straps or Wheels can be adjusted in a large area too to change thick products. A clamping device (claim 2) ensures that the timing belt is always properly tensioned is over for an exact positive drive and circulation to care.

In vorteilhafter Weise ist die Vorrichtung so ausgestaltet wie in den Ansprüchen 3 bis 5 angegeben.The device is advantageously designed in this way as indicated in claims 3 to 5.

Im folgenden wird die Erfindung unter Hinweis auf die Zeichnung anhand eines Ausführungsbeispieles näher erläutert.In the following the invention with reference to the drawing explained in more detail using an exemplary embodiment.

Die in der Zeichnung dargestellte Vorrichtung zum Vereinzeln von Papier-, Kartonzuschnitten oder dgl. unterschiedlicher Dicke, die mit 11 bezeichnet sind, besteht aus zwei Bewegungsgruppen, nämlich einer Friktionsbaugruppe und einer Förderbaugruppe. Die Friktionsbaugruppe wird durch Friktionsfördergurte oder -Räder 2 und mit diesen zusammenarbeitenden feststehenden oder langsam gegenläufigen Rädern 4 gebildet, die zusammen eine Produktschleuse bilden. Die nachgeschaltete Förderbaugruppe wird durch ein Wellenpaar mit Förderrollen oder -Gurten 3a, 3b gebildet. Die Wellen dieser Förderbaugruppe werden mit höherer Geschwindigkeit angetrieben, damit die innerhalb der Friktionsbaugruppe getrennten Zuschnitte schneller als in der Vorförderung weitergefördert und damit sauber von dem nachfolgenden Produkt getrennt werden.The separating device shown in the drawing of paper, cardboard blanks or the like. different Thickness, designated 11, consists of two movement groups, namely a friction assembly and one Conveyor assembly. The friction assembly is replaced by friction conveyor belts or wheels 2 and cooperating with them stationary or slowly counter-rotating wheels 4 are formed, which together form a product lock. The downstream Conveyor assembly is supported by a pair of shafts Conveyor rollers or belts 3a, 3b are formed. The waves of this Conveyor assemblies are driven at higher speeds so that those separated within the friction assembly Cuttings are conveyed faster than in pre-funding and thus be separated cleanly from the subsequent product.

Der Abstand zwischen den Fördermitteln der einzelnen Baugruppen ist verstellbar. Dieses ist durch Doppelpfeile 7 und 8 angedeutet. Hierdurch erfolgt die Anpassung an unterschiedlich dicke Produkte.The distance between the funding of the individual modules is adjustable. This is by double arrows 7 and 8 indicated. As a result, the adaptation to different takes place thick products.

Der gemeinsame Antrieb 1 treibt einen doppelseitigen Zahnriemen, d.h. einen Zahnriemen, der auf beiden Seiten Zähne aufweist, so daß er auch beidseitig für eine entsprechende formschlüssige Kraftübertragung sorgen kann. Dieser Zahnriemen umschlingt wie in Fig. 2 dargestellt, die Zahnscheiben der anzutreibenden Wellen. Dieses sind bei der dargestellten Ausführungsform die Wellen der Friktionsfördergurte oder -Räder 2 und der Förderrollen oder -Räder 3a und 3b der nachgeschalteten Förderbaugruppe. Eine Spannvorrichtung 6, die schematisch in Fig. 2 dargestellt ist, sorgt dafür, daß der doppelseitige Zahnriemen 5 immer die gewünschte Spannung aufweist, je nach dem, wie die Verstellung bei 8 erfolgt. Es ist erkennbar, daß zum Antrieb in die gewünschte Richtung mal die eine und mal die andere gezahnte Seite des Zahnriemens 5 wirksam wird.The common drive 1 drives a double-sided toothed belt, i.e. a timing belt that has teeth on both sides has, so that it also on both sides for a corresponding can provide positive power transmission. This timing belt wraps around the toothed disks as shown in FIG. 2 of the waves to be driven. These are shown in the Embodiment the waves of the friction conveyor belts or -Wheels 2 and the conveyor rollers or -wheels 3a and 3b the downstream conveyor assembly. A tensioning device 6 which is shown schematically in Fig. 2, ensures that the double-sided toothed belt 5 always the desired tension has, depending on how the adjustment is made at 8. It can be seen that to drive in the desired direction sometimes the one and the other toothed side of the timing belt 5 takes effect.

Die langsam taktweise gegenläufig drehenden Räder 4 werden über einen Freilauf getaktet, der über einen Arm 7 mit einem Exzenter 10 auf der Welle der Förderrollen oder -Räder 3a ausgebildet ist. Die Welle ist in einem zweiten Freilauf gelagert, der die Drehung der Welle nur in Schaltrichtung des Hebelsarms zuläßt. Bei der Rückführung des Hebels ist die Drehbewegung der Welle durch den zweiten Freilauf gesperrt, so daß durch eine Hin- und Herbewegung des Armes 9 eine einläufige Zwangsbewegung der Welle und damit der Räder 4 entsteht.The slowly rotating counterclockwise wheels 4 are clocked via a freewheel, the arm 7 with a Eccentric 10 on the shaft of the conveyor rollers or wheels 3a is trained. The shaft is supported in a second freewheel, which only rotates the shaft in the switching direction of the Allows lever arm. When returning the lever is the Rotation of the shaft blocked by the second freewheel, so that a reciprocating movement of the arm 9 a one-way The shaft and thus the wheels 4 are forced to move.

Es ist leicht erkennbar, daß die gewünschte Verstellung zur Anpassung an unterschiedlich dicke Produkte in einem großen Bereich erfolgen kann, da durch den Antrieb mit dem doppelseitigen Zahnriemen eine entsprechend große Anpassung möglich ist. Lediglich die Spannvorrichtung muß für die Aufrechterhaltung der gewünschten Spannung in dem Zahnriemen 5 sorgen. Es wird nach wie vor ein gemeinsamer Antrieb 1 eingesetzt, wobei aber eine Anpassung an sehr unterschiedliche Produkte problemlos möglich ist.It is easy to see that the desired adjustment for Adaptation to products of different thicknesses in one large Area can be done because of the drive with the double-sided Toothed belt a correspondingly large adjustment possible is. Only the jig has to be maintained the desired tension in the toothed belt 5 to care. A common drive 1 is still used, but an adaptation to very different Products is easily possible.
