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.

Bei derartigen bekannten Vorrichtungen ist die Übergabe von dem Vakuumförderer auf den Träger problematisch, insbesondere dann, wenn ein positionsgenaues Ablegen erwünscht ist.In such known devices, the transfer of the vacuum conveyor on the carrier problematic, in particular then when a positionally accurate deposit is desired.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung nach dem Oberbegriff des Anspruches 1 zu schaffen, durch die ein positionsgenaues Ablegen der Zuschnitte auf eine mit hoher Geschwindigkeit kontinuierlich bewegte Oberfläche sichergestellt ist.The invention is therefore based on the object of a device to create according to the preamble of claim 1, through the precise positioning of the blanks one continuously moving at high speed Surface is ensured.

Diese Aufgabe wird grundsätzlich durch das Kennzeichen des Anspruches 1 gelöst.This task is fundamentally characterized by the Claim 1 solved.

Dadurch, daß die Zuschnitte, beispielsweise Telefonkarten oder dergleichen, auf dem Untergurt des Vakuumförderers gefördert werden, gelangen sie glatt und ohne abrupten Übergang, also "tangential", auf die Oberfläche des Trägers. Wenn der Vakuumförderer und der Träger dann mit gleicher Geschwindigkeit laufen, wenn die Übergabe eines Zuschnittes erfolgt, ist ein punktgenaues Übergeben sichergestellt. Dadurch, daß der Vakuumförderer schneller angetrieben wird, als die Vereinzelung erfolgt, ist zwischen den Zuschnitten an dem Vakuumförderer ein Abstand vorhanden. Dieser Abstand oder diese Lücke wird zur Steuerung, beispielsweise mit Hilfe eines Sensors (Ansprüche 4 und 5) genutzt.The fact that the blanks, for example phone cards or the like, conveyed on the lower belt of the vacuum conveyor they go smoothly and without an abrupt transition, so "tangential" on the surface of the carrier. If the vacuum conveyor and the carrier then with the same Speed run when handing a blank is carried out, precise handover is ensured. Because the vacuum conveyor is driven faster, as the singulation takes place, is between the blanks there is a clearance on the vacuum conveyor. This distance or this gap becomes control, for example with Using a sensor (claims 4 and 5) used.

Wenn die Vorrichtung in vorteilhafter Weise so ausgebildet ist, wie in den Ansprüchen 2 und 3 angegeben, so sorgen die Andrückrollen für einen glatten und genauen Übergang von dem Vakuumförderer auf die Oberfläche des Trägers. Die im Takt erfolgende Bewegung des Vakuumförderers erfolgt so, daß dieser sich bei Übergabe eines Zuschnittes auf die Oberfläche des Trägers immer mit der Geschwindigkeit des Trägers bewegt, so daß es nicht zu Problemen durch unterschiedliche Fördergeschwindigkeiten kommt. Die Lücken zwischen den Zuschnitten sind ausreichend, um den kurzzeitig stillstehenden Vakuumförderer immer wieder auf die gewünschte Geschwindigkeit zu beschleunigen.If the device is designed in an advantageous manner is, as stated in claims 2 and 3, provide Pinch rollers for a smooth and precise transition from the vacuum conveyor onto the surface of the carrier. The in Movement of the vacuum conveyor takes place cyclically that this applies to the delivery of a blank Surface of the carrier always at the speed of the Carrier moves so that there are no problems caused by different Conveyor speeds is coming. The gaps between the blanks are sufficient to briefly idle vacuum conveyors always on the accelerate desired speed.

Die in der Zeichnung dargestellte Vorrichtung dient dem Vereinzeln von Papier-, Karton- oder Kunststoffzuschnitten 2, beispielsweise Telefonkarten oder dergleichen, die in einer Stapelvorrichtung 10 übereinandergestapelt sind. Der unterste Zuschnitt in dem Stapel 10 wird von einer Vereinzelungsvorrichtung 3 in Form eines Endlosförderers erfaßt und an die Unterseite eines Vakuumförderers 4 übergeben, der ebenfalls als Endlosförderer ausgebildet ist. Die Vakuumöffnungen in dem endlosen Förderband des Vakuumförderers 4 werden von einer Vakuumkammer mit Unterdruck beaufschlagt.The device shown in the drawing serves the Separation of paper, cardboard or plastic blanks 2, for example phone cards or the like, which in a stacking device 10 are stacked one on top of the other. The lowest blank in the stack 10 is from a separating device 3 recorded in the form of an endless conveyor and passed to the bottom of a vacuum conveyor 4, the is also designed as an endless conveyor. The vacuum openings in the endless conveyor belt of the vacuum conveyor 4 are pressurized by a vacuum chamber.

An dem Abgabeende, das von der Vereinzelungsvorrichtung 3 entfernt liegt, trifft der Vakuumförderer 4 auf die Oberfläche eines Trägers 1, der kontinuierlich bewegt wird, und auf dem die Zuschnitte einzeln positionsgenau übergeben werden. An diesem Ende befinden sich zwei Andrückrollen 9, die frei mitlaufend auf der Welle 8 des Vakuumförderers, um die das Förderband umläuft, gelagert sind.At the discharge end, which is from the separating device 3 is removed, the vacuum conveyor 4 hits the surface a carrier 1 which is continuously moved, and on which the blanks are transferred individually in precise positions become. At this end there are two pressure rollers 9, the free running on the shaft 8 of the vacuum conveyor to around the conveyor belt are stored.

Angrenzend an dieses Ende befindet sich unterhalb des Vakuumförderers 4 ein Sensor 6, der die taktweise Bewegung des Vakuumförderers steuert.Adjacent to this end is below the Vacuum conveyor 4 a sensor 6, the cyclical movement controls the vacuum conveyor.

Im Betrieb bewegt sich der Vakuumförderer 4 mit den von ihm mitgenommenen Zuschnitten 2 schneller vorwärts als der endlose Förderer, der die Vereinzelungsvorrichtung 3 bildet. Hierdurch entstehen Lücken 5 zwischen den Zuschnitten 2. Der Strom der Zuschnitte wird durch den Sensor 6 gesteuert, d.h. wenn ein Zuschnitt 2 den Sensor 6 erreicht, wird der Vakuumförderer angehalten. Der Sensor 6 ist in Laufrichtung verstellbar, um die Zuschnitte 2 in der Stillstands- und Ausgangsstellung in Laufrichtung bestimmbar zu machen. Die Oberfläche des Trägers 1 wird kontinuierlich bewegt und ist mit einem Synchronsignalgeber ausgerüstet, der seine Signale an den Eingang der Synchronlaufregelung des oder der Servorantriebe für die Bewegung der Vereinzelungsvorrichtung 3 und des Vakuumförderers 4 leitet.In operation, the vacuum conveyor 4 moves with it carried blanks forward 2 faster than that endless conveyor, which forms the separating device 3. This creates gaps 5 between the blanks 2. The flow of the blanks is controlled by the sensor 6, i.e. when a blank 2 reaches the sensor 6, is the vacuum conveyor stopped. The sensor 6 is in the running direction adjustable to the blanks 2 in the standstill and make the starting position in the direction of travel determinable. The surface of the carrier 1 is continuously moved and is equipped with a synchronous signal generator, its Signals to the input of the synchronism control of the or the servo drives for the movement of the separating device 3 and the vacuum conveyor 4 conducts.

Der Start für die Auslösung eines Arbeitstaktes wird durch den Abgriff einer Winkelposition eines Drehwinkelsignalgebers oder eines Kantensteuersignals ausgelöst. Der unter dem Sensor 6 plazierte Zuschnitt wird durch Auslösung des Taktes unter Verwendung der Signale des Synchronsignalgebers in Gleichlauf zu dem kontinuierlich laufenden Träger 1 gebracht und im Wendepunkt 7 des endlosen Unterdruckförderbandes synchron auf den Träger 1 aufgebracht. Der Zuschnitt wird hierbei durch die frei mitlaufenden Andrückrollen 8 angedrückt. Die Position des auf den Träger aufgebrachten Produktes wird durch einen Haftvermittler gesichert.The start for the triggering of a work cycle is by the tapping of an angular position of a rotary signal generator or an edge control signal triggered. The under the sensor 6 placed blank is triggered by triggering the Clock using the signals of the synchronous signal generator in synchronization with the continuously running carrier 1 brought and at the turning point 7 of the endless vacuum conveyor belt applied synchronously to the carrier 1. The cut is here by the freely running pressure rollers 8th pressed. The position of the applied to the carrier Product is secured by an adhesion promoter.

Durch die Lücken zwischen den Zuschnitten besteht bei Beginn eines neuen Taktes ausreichend Zeit, daß der Vakuumförderer auf die Geschwindigkeit des Trägers 1 beschleunigt wird, so daß die beiden Geschwindigkeiten bei einer Übergabe eines Zuschnittes miteinander synchronisiert sind.Due to the gaps between the blanks there is at Start of a new cycle enough time that the vacuum conveyor accelerated to the speed of the carrier 1 is so that the two speeds at a handover of a blank are synchronized with each other.
