Description

Die vorliegende Erfindung betrifft ein Verfahren zum Ergreifen eines bewegten flachen Produkts gemäß dem Oberbegriff von Anspruch 1 und eine Vorrichtung zum Ergreifen eines bewegten flachen Produkts dem Oberbegriff von Anspruch 8.The present invention relates to a method for gripping a moving flat Product according to the preamble of claim 1 and a device for gripping a moving flat product the preamble of claim 8.

Zum Erfassen und Transportieren von Signaturen in einem Falzapparat werden häufig Schaufelräder eingesetzt. Die Kurvenform und die unebene Oberfläche der das Schaufelrad bildenden Schaufelblätter bremsen die Vorwärtsbewegung der abgelegten Signaturen. Die aus aneinandergrenzenden Schaufelblättern gebildeten Taschen des Schaufelrads nehmen die Signaturen auf, nachdem diese den Falzapparat verlassen haben. Ein Nachteil derartiger Vorrichtungen besteht darin, dass die Signaturen an den Taschen des Schaufelrads eingerissen oder auf andere Weise beschädigt werden können, da die Signaturen mit hoher Geschwindigkeit in den Taschen abgelegt werden.To capture and transport signatures in a folder are common Paddle wheels used. The curve shape and the uneven surface of the paddle wheel Forming shovel blades slow down the forward movement of the stored signatures. The Take pockets of the impeller formed from adjacent impeller blades the signatures after they have left the folder. A disadvantage of that Devices is that the signatures on the pockets of the paddle wheel torn or otherwise damaged because the signatures are high Speed in your pockets.

Die US 4,629,175 offenbart eine Vorrichtung zur Beseitigung dieser Probleme. Die Vorrichtung umfasst Reihen von Greifern, die zwischen einer Zuführvorrichtung und einem nachfolgenden Auslegesystem rotieren. Die Greifer befinden sich an einer zylindrischen Trommel, die mit konstanter Geschwindigkeit rotiert, und die Greiferreihen werden von einem Antrieb auf die Geschwindigkeit der Zuführvorrichtung beschleunigt und anschließend auf die Geschwindigkeit des Auslegesystems gebremst. Hierbei besteht jedoch die Gefahr, dass die Signaturen beschädigt werden, da die Greifer in eine Position vor einer Vorderkante der von der Zuführvorrichtung zugeführten Signatur gedreht werden. Hierzu kommt es, da die Geschwindigkeit der Signatur auf der Zuführvorrichtung größer sein muss als eine Tangentialgeschwindigkeit des Greifers. Die Signatur bewegt sich also schneller als der Greifer, wenn sie in den Greifer einläuft und dieser sich um sie schließt. Dabei wird die Vorderkante der Signatur sofort auf die Geschwindigkeit des Greifers gebremst, während sich die Hinterkante jedoch noch in der Kontrolle der Zuführvorrichtung befindet und sich daher mit einer höheren Geschwindigkeit bewegt als die Vorderkante. Durch diese unterschiedlichen Geschwindigkeiten besteht die Gefahr, dass die Signatur beschädigt wird. US 4,629,175 discloses an apparatus for eliminating these problems. The The device comprises rows of grippers that are between a feed device and rotate a subsequent delivery system. The grippers are on one cylindrical drum that rotates at a constant speed, and the rows of grippers are accelerated by a drive to the speed of the feed device and then braked to the speed of the delivery system. Here there is however, there is a risk that the signatures will be damaged since the grippers are in one position are rotated in front of a leading edge of the signature fed by the feeder. This occurs because the speed of the signature on the feeder is greater must be as a tangential speed of the gripper. So the signature moves faster than the gripper when it enters the gripper and it closes around it. The front edge of the signature immediately adjusts to the speed of the gripper braked while the trailing edge is still in control of the Feeder is located and therefore moves at a higher speed than the leading edge. Due to these different speeds, there is a risk that the signature is damaged.

In der US 5,452,886 ist eine Bremstrommel zum Abbremsen von in einem Falzapparat transportierten Signaturen beschrieben. Die Trommel umfasst eine Vielzahl von Schwenkarmen, die mit einer rotierenden Drehscheibe verbunden sind und sich unabhängig voneinander drehen können. Jeder Schwenkarm ist mit einem Steuerhebel verbunden, dessen andere Seite mit einer rotierenden Steuerscheibe verbunden ist. Die rotierende Steuerscheibe ermöglicht eine Beschleunigung und ein Abbremsen einer Signatur. Ein an dem Schwenkarm angeordneter Greifer erfasst die Signatur, wenn diese in die Bremstrommel einläuft. Das System ist vorzugsweise zeitlich so abgestimmt, dass die Vorderkante der einlaufenden Signatur vom Greiferkopf erfasst wird, bevor die Hinterkante der Signatur von einem Förderbandsystem freigegeben wird. Auch hier wird die Signatur mit hoher Geschwindigkeit an den Greifer übergeben und von diesem erfasst, während sie noch von dem Fördersystem gehalten wird. Daher kann die Signatur bei der Übergabe beschädigt werden.In US 5,452,886 there is a brake drum for braking in a folder transported signatures described. The drum includes a variety of Swivel arms that are connected to a rotating turntable and are independent can rotate from each other. Each swivel arm is connected to a control lever, the other side of which is connected to a rotating control disk. The rotating one Control disc enables acceleration and deceleration of a signature. An on the gripper arranged gripper detects the signature when it is in the Brake drum runs in. The system is preferably timed so that the The leading edge of the incoming signature is captured by the gripper head before the Trailing edge of the signature is released by a conveyor belt system. Here too hand over the signature to the gripper at high speed and capture it, while still being held by the conveyor system. Therefore, the signature at the Handover will be damaged.

Fig. 1 zeigt eine Greiferanordnung 31 mit einem Schwenkarm 1, der in die durch den Pfeil 17 angezeigte Richtung um einen Schwenkpunkt 7 rotiert. Ein Greiferarm 8 ist an einer oberen Gelenkstange 16 angeordnet und teilweise um einen Schwenkpunkt 9 schwenkbar. Die obere Gelenkstange 16 ist wiederum am Schwenkarm 1 um einen Schwenkpunkt 10 schwenkbar gelagert. Der Greiferarm 8 ist außerdem über eine an dem Greiferarm 8 angeordnete Stange 21 in einem Schwenkpunkt 4 mit einer unteren Gelenkstange 6 verbunden. Die Stange 21 ist um einen aus der Gelenkstange 6 heraus ragenden Stift 4' schwenkbar. Die untere Gelenkstange 6 ist wiederum in einem Schwenkpunkt 3 am Schwenkarm 1 angeordnet und um einen aus dem Schwenkarm 1 heraus ragenden Stift 3' im Schwenkpunkt 3 schwenkbar.Fig. 1 shows a gripper assembly 31 with a swivel arm 1, which in the arrow 17 direction rotated about a pivot point 7. A gripper arm 8 is on one Upper joint rod 16 arranged and partially pivotable about a pivot point 9. The upper joint rod 16 is in turn on the pivot arm 1 about a pivot point 10 pivoted. The gripper arm 8 is also connected to the gripper arm 8 arranged rod 21 in a pivot point 4 with a lower joint rod 6 connected. The rod 21 is around a pin 4 'protruding from the joint rod 6 pivotable. The lower joint rod 6 is in turn at a pivot point 3 Swivel arm 1 arranged and around a pin 3 'protruding from the swivel arm 1 pivotable at pivot point 3.

An einem Ende des Greiferarms 8 ist ein Greifer 15 befestigt. Eine Greiferauflage 18 ist am Schwenkarm 1 befestigt. Eine Kurvenrolle 5 ist an der unteren Gelenkstange 6 angeordnet und um einen Schwenkpunkt 2 herum gelagert. Die Position der Kurvenrolle 5 bestimmt die Position des Greiferarms 8 und so auch die Position des Greifers 15 relativ zum Schwenkarm 1.A gripper 15 is attached to one end of the gripper arm 8. A gripper pad 18 is on Swivel arm 1 attached. A cam roller 5 is arranged on the lower joint rod 6 and stored around a pivot point 2. The position of the cam roller 5 determines the position of the gripper arm 8 and thus also the position of the gripper 15 relative to Swivel arm 1.

Der Greifer 15 befindet sich in Fig. 1 unmittelbar unter einem Bereich 13 zwischen einer Hinterkante einer Signatur 14 und einer Vorderkante der nächsten Signatur 12. Die Signaturen 12, 14 werden in die durch den Pfeil 11 angezeigte Richtung transportiert. Die Position des Schwenkarms 1 wird durch die Drehung des Schwenkarms 1 um den Schwenkpunkt 7 gesteuert. Die Signaturen 12, 14 werden auf einem Bandsystem 20 gefördert und an die Greiferanordnung 31 übergeben.The gripper 15 is located in FIG. 1 directly under an area 13 between one Trailing edge of a signature 14 and a leading edge of the next signature 12. The Signatures 12, 14 are transported in the direction indicated by arrow 11. The The position of the swivel arm 1 is determined by the rotation of the swivel arm 1 Swivel point 7 controlled. The signatures 12, 14 are on a tape system 20 promoted and passed to the gripper assembly 31.

In Fig. 2 ragt der Greifer 15 nach einer Weiterdrehung des Schwenkarms 1 in dem Bereich 13 zwischen der Hinterkante und der Vorderkante der Signaturen 12, 14 hervor.In Fig. 2, the gripper 15 protrudes after a further rotation of the swivel arm 1 in the area 13 between the rear edge and the front edge of the signatures 12, 14.

Fig. 3 zeigt den weiteren Ablauf, bis sich der Schwenkarm 1 so weit gedreht hat, dass die Greiferauflage 18 unmittelbar mit der Vorderkante der Signatur 12 ausgerichtet ist. In der in Fig. 3 gezeigten Position bewegen sich die Signatur 12 und die Greiferauflage 18 in dieselbe Richtung 11 und mit derselben Geschwindigkeit. Bestimmt durch die Position bzw. Bewegung der Kurvenrolle 5 hat außerdem der Greifer 15 begonnen, sich zu schließen. Fig. 3 shows the further process until the swivel arm 1 has rotated so far that the Gripper pad 18 is aligned directly with the front edge of the signature 12. In the 3, the signature 12 and the gripper pad 18 move in the same direction 11 and at the same speed. Determined by the position or movement of the cam roller 5, the gripper 15 has also started to conclude.

In Fig. 4 bewegt sich der Schwenkarm 1 mit derselben Geschwindigkeit wie die Signatur 12, während der Greifer 15 sich vollständig um die Signatur 12 schließt, indem diese gegen die Greiferauflage 18 erfasst wird. Auf diese Weise wird die Signatur 12 vom Bandsystem 20 abgenommen und weitertransportiert. Es wird darauf hingewiesen, dass keine abrupte Änderung der Geschwindigkeit des Greifers 15 vorgenommen wird, nachdem die Signatur 12 erfasst wurde. Die Signatur 12 wird ohne die aus dem Stand der Technik bekannten unerwünschten Nebeneffekte wie z.B. abrupte Verzögerung oder Beschleunigung, d. h. Geschwindigkeitsänderungen, weitertransportiert. Außerdem stößt der Greifer 12 nicht an die Kante der Signatur, um diese bei seiner Rückbewegung zu erfassen. Dies reduziert die Gefahr, die Signatur 12 zu beschädigen.4, the swivel arm 1 moves at the same speed as the signature 12, while the gripper 15 closes completely around the signature 12 by this against the gripper pad 18 is detected. In this way, the signature 12 from the tape system 20 removed and transported on. It should be noted that no abrupt Change in speed of the gripper 15 is made after the signature 12 was recorded. The signature 12 is without those known from the prior art undesirable side effects such as abrupt deceleration or acceleration, d. H. Changes in speed, transported on. In addition, the gripper 12 does not strike the edge of the signature to capture it as it moves back. This reduces the Risk of damaging signature 12.

Fig. 1-4 sind stark schematisiert dargestellt. Fig. 5-8 zeigen weitere Details der Erfindung.1-4 are shown very schematically. 5-8 show further details of the invention.

Fig. 5 zeigt eine perspektivische Darstellung der Greiferanordnung 31, in der der Greiferarm 8 mit einer Vielzahl von Greifern 15 gezeigt ist. Der Schwenkarm 1 trägt eine Vielzahl von Greiferauflagen 18. Die obere Gelenkstange 16 weist einen Stift 22 auf, welcher sich in einer im Schwenkarm 1 angeordneten Bohrung 26 dreht und den Schwenkpunkt 10 definiert. Die obere Gelenkstange 16 umfasst außerdem einen zylindrischen Abschnitt 23, um welchen der Greiferarm 8 rotiert und der den Schwenkpunkt 9 definiert. Der Greiferarm 8 ist um den Schwenkpunkt 9 drehbar und vertikal bewegbar, da zwischen der Unterseite der oberen Gelenkstange 16 und dem Greiferarm 8 ein Zwischenraum besteht. Die Kurvenrolle 5 rollt auf einer Kurvenscheibe 24 mit einer Kontur oder Kurvenbahn 25. Bei Drehung der Kurvenscheibe 24 durch die Kurvenrolle 5 folgt die Stange 21 des Greiferarms 8 der Kontur 25 der Kurvenscheibe 24. Durch die Höhen- und Richtungsveränderung der Kontur 25 bewegt sich der Greiferarm 8 auf und ab sowie in einem Winkel auf den Schwenkarm 1 zu oder von diesem weg. Durch die Aufwärts- und Abwärtsbewegung wird der Greifer 15 auf die Greiferauflage 18 zu und von dieser weg bewegt. Durch die Schräg- oder Drehbewegung wird der Greiferarm 8 auf den Schwenkarm 1 zu oder von diesem weg bewegt. Der Schwenkarm 1 umfasst weiterhin einen Kanal 27, in dem die Stange 21 des Greiferarms 8 geführt wird. Fig. 5 shows a perspective view of the gripper assembly 31, in which the Gripper arm 8 is shown with a plurality of grippers 15. The swivel arm 1 carries one A large number of gripper pads 18. The upper joint rod 16 has a pin 22, which rotates in a bore 26 arranged in the swivel arm 1 and the Defined pivot point 10. The upper link 16 also includes one cylindrical portion 23 about which the gripper arm 8 rotates and the Define pivot point 9. The gripper arm 8 is rotatable about the pivot point 9 and vertically movable, since between the underside of the upper joint rod 16 and the Gripper arm 8 there is a space. The cam roller 5 rolls on a cam 24 with a contour or curved path 25. When the cam 24 rotates through the Cam roller 5 follows the rod 21 of the gripper arm 8 of the contour 25 of the cam disk 24. The gripper arm 8 moves due to the change in height and direction of the contour 25 up and down as well as at an angle towards or away from the swivel arm 1. By the upward and downward movement of the gripper 15 towards the gripper pad 18 and moved away from this. The gripper arm 8 is opened by the oblique or rotary movement the swing arm 1 moves to or away from this. The swivel arm 1 also includes a channel 27 in which the rod 21 of the gripper arm 8 is guided.
