Eine Vorrichtung dieser Art ist aus der DE 40 29 520 bekannt. Sie dient einem einzelnen Entnehmen von Verpackungszuschnitten aus einem Magazin und einem Einsetzen dieser Zuschnitte in Fächer eines Transportbandes. Bei diesem Einsetzen werden die Zuschnitte mittels eines Steuermechanismus mit Steuerkurve durch eine Radialbewegung der Saugerarme weg vom Rotor in die Fächer gedrückt und dabei umgeformt.A device of this type is known from DE 40 29 520. It serves you individual removal of packaging blanks from a magazine and one Inserting these blanks into compartments on a conveyor belt. With this onset are the blanks by means of a control mechanism with a control curve by a Radial movement of the suction arms pressed away from the rotor into the compartments while doing so reshaped.

Die bekannte Vorrichtung hat den Nachteil, dass der Steuermechanismus technisch relativ aufwendig ist. Der Erfindung liegt daher die Aufgabe zu Grunde, eine Vorrichtung der eingangs beschriebenen Art, jedoch ohne Steuermechanismus, zu schaffen.The known device has the disadvantage that the control mechanism is technically is relatively expensive. The invention is therefore based on the object Device of the type described above, but without a control mechanism create.

Gelöst ist die Aufgabe gemäß dem kennzeichnenden Teil des Anspruchs 1. Danach ist am Rotor ein Planetengetriebe vorgesehen, welches die Zykloidenbahn beschreibt, und die Sauger sind parallel zueinander und vorzugsweise zur Transportrichtung der Transportvorrichtung ausgerichtet.The problem is solved according to the characterizing part of claim 1. After that a planetary gear is provided on the rotor, which describes the cycloid orbit, and the suction cups are parallel to one another and preferably to the transport direction of the Transport device aligned.

Die erfindungsgemäße Vorrichtung hat den Vorteil, dass sie in technisch einfacher Weise und ohne Steuermechanismus funktioniert. Das Planetengetriebe ist ein herkömmliches Getriebe, welches an sich die Zykloidenbahn erzeugt. Die Sauger sind parallel zueinander ausgerichtet und verbleiben stets in dieser Richtung während ihres Umlaufs. Somit ist auch deren Verbindung mit dem Planetengetriebe in einfacher Weise realisierbar. Die Sauger werden durch die Zyloidenbahn an einen Gegenstand herangeführt, dann mitsamt dem Gegenstand zur Abgabestation bewegt und schließlich wieder an einen nachfolgenden Gegenstand gesetzt. The device according to the invention has the advantage that it is technically simpler Works wisely and without a control mechanism. The planetary gear is a conventional gearbox, which generates the cycloid orbit. The suckers are aligned parallel to each other and always remain in this direction during their Circulation. Thus, their connection to the planetary gear is easier Way feasible. The suction cups are attached to an object by the cyloid path brought up, then moved together with the object to the delivery station and finally put back on a subsequent item.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Ansprüchen 2 bis 6 beschrieben.Further advantageous embodiments of the invention are in claims 2 to 6 described.

Eine optimale zeitliche Nutzung der Vorrichtung ist erreicht, wenn gemäß den Ansprüchen 2 und 3 an der Vorrichtung drei oder vier Saugerarme bzw. Saugerarmpaare vorgesehen sind. Wird ein Gegenstand von einem Saugerarmpaar ergriffen, so sind seine Entnahme und sein Weitertransport sicherer als wenn er nur von einem einzelnen Saugerarm bewegt werden soll. Dem gleichen Zweck dienen auch mehrere Sauger an einem Saugerarm.An optimal use of the device over time is achieved if according to the Claims 2 and 3 on the device three or four suction arms or Sucker arm pairs are provided. Becomes an object from a pair of suction arms seized, its removal and onward transport are safer than if it were only to be moved by a single suction arm. Serve the same purpose also several suction cups on one suction arm.

Ist der Rotor kontinuierlich angetrieben (Anspruch 4), so wird eine besonders hohe Rate für die Gegenstandsübergabe erreicht, da ein Stillstand des Rotors vermieden wird. Mittels Servotechnik kann dabei an den für ein Handling der Gegenstände relevanten Spitzen der Zyloidenbahn die Bewegung des Rotors verlangsamt werden, um derart das Handling noch zuverlässiger zu machen.If the rotor is driven continuously (claim 4), then a particularly high Item handover rate reached as rotor standstill avoided becomes. Servo technology can be used to handle the objects relevant peaks of the cyloid orbit the movement of the rotor is slowed down, to make handling even more reliable.

Aus einem Magazin (Anspruch 5) können flache Faltschachtelzuschnitte entnommen werden, um sie dann entlang der Zyloidenbahn an einer Führung aufzurichten (Anspruch 6). Die Zuschnitte werden dazu mit einer vorgefalteten Kante an der Führung entlangbewegt. Die Führung ist der Zykloidenbahn derart angepasst, dass sich beim Weiterbewegen des Zuschnitts der Abstand zwischen der Zykloidenbahn und der Führung verringert, um derart den Zuschnitt zu stauchen und dabei die Faltschachtel aufzurichten. Die aufgerichtete Faltschachtel wird anschließend an die Transportvorrichtung abgegeben.Flat folding box blanks can be removed from a magazine (claim 5) to erect them on a guide along the Cyloid Railway (Claim 6). The blanks are with a pre-folded edge on the Moved along the guide. The guide is adapted to the cycloid orbit in such a way that the distance between the cycloid trajectory as the blank is moved and the guide reduced so as to compress the blank and thereby the Erect folding box. The erected folding box is then attached to the Delivered transport device.

Die Vorrichtung enthält ein Planetengetriebe 1, das eine vierbogige Zykloidenbahn Z beschreibt, sowie weitere, überlagerte Getriebestufen 2,3, die eine Gesamtübersetzung von 1:1 vom Gestell 4 auf die Saugerarme 5 bewirken, so dass diese einerseits eine Zykloidenbahn Z beschreiben, gleichzeitig aber immer parallel zu einer Geraden im Gestell 4 bleiben.The device contains a planetary gear 1, which has a four-arc cycloidal path Z describes, as well as other, superimposed gear stages 2,3, which a total translation effect of 1: 1 from the frame 4 to the suction arms 5, so that these on the one hand describe a cycloid orbit Z, but at the same time always parallel to one Stay straight in frame 4.

Das Planetengetriebe 1 besteht aus einem Rotor 6, der mit der Antriebswelle 7 fest verbunden und im Gestell 4 gelagert ist. Auf dem Rotor 6 befinden sich drei Planeten 8, die aus der Hohlwelle 9, dem Stirnrad 10 und der Kurbel 11 bestehen. Das Stimrad 10 und die Kurbel 11 sind fest mit der Hohlwelle 9 verbunden. In den Planeten 8 sind die Wellen 12 gelagert, an denen sich die Saugerarme 13 mit den Saugem 14 befinden.The planetary gear 1 consists of a rotor 6, which is fixed to the drive shaft 7 connected and stored in the frame 4. There are three planets on the rotor 6 8, which consist of the hollow shaft 9, the spur gear 10 and the crank 11. The spur wheel 10 and the crank 11 are firmly connected to the hollow shaft 9. In the planet 8 are the shafts 12 are mounted on which the suction arms 13 with the suction elements 14 are located.

Für die Erzeugung der vierbogigen Zykloide ist eine Übersetzung vom Stimrad 9 zum gestellfesten Stirnrad mit i=4 verwendet, wobei auf dem Rotor 6 das Zwischenrad 16 gelagert ist. Der Radius des Planeten F verhält sich zum Radius des Rotors E ungefähr 1:3.For the generation of the four-armed cycloid, a translation from the spur wheel 9 to spur gear fixed to the frame with i = 4, the idler gear 16 on the rotor 6 is stored. The radius of the planet F is roughly related to the radius of the rotor E. 1: 3.

Um die Parallelität der Sauger 14 zum Gestell 4 zu realisieren, sind die Getriebestufen 2 und 3 dem Planetengetriebe 1 überlagert. Die Getriebestufe 3 besteht aus einem Rotor 17, der exzentrisch zur Antriebswelle 7 im Gestell 4 gelagert ist, einer Welle 19, die koaxial in der Hohlwelle 9 gelagert ist und einer Kurbel 18, die fest mit der Welle 19 verbunden ist. Um eine Übersetzung von 1:1 vom Gestell 4 auf die Welle 19 zu realisieren, muß die Exzentrizität G dem Kurbelradius H entsprechen. Die Funktionsweise entspricht somit einer "halben" Schmidt-Kupplung. Die Getriebestufe 2 besteht aus einem Stirnrad 20, das mit der Welle 19 fest verbunden ist, einem weiteren Stimrad 22, das mit der Welle 12 fest verbunden ist und einem Zwischenrad 21, das auf der Kurbel 11 gelagert ist. Hierbei müssen die Zähnezahlen der Stimräder 20 und 22 identisch sein. In order to realize the parallelism of the suction cups 14 to the frame 4, the gear stages are 2 and 3 superimposed on the planetary gear 1. Gear stage 3 consists of a Rotor 17, which is mounted eccentrically to the drive shaft 7 in the frame 4, a shaft 19, which is mounted coaxially in the hollow shaft 9 and a crank 18 which is fixed to the shaft 19 connected is. To a ratio of 1: 1 from frame 4 to shaft 19 realize, the eccentricity G must correspond to the crank radius H. The Operation corresponds to a "half" Schmidt coupling. Gear stage 2 consists of a spur gear 20 which is fixedly connected to the shaft 19, another Stim wheel 22, which is fixedly connected to the shaft 12 and an idler gear 21, the is mounted on the crank 11. The number of teeth of the spur gears 20 and 22 be identical.

Fährt der Saugerarm 13, der Teil eines Saugerarmpaares ist, in den Bereich der Spitze A, so wird ein Zuschnitt 34 aus dem Magazin 23 angesaugt, und bei Verlassen des Saugerarms 13 der Spitze A wird dieser Zuschnitt 34 von den Saugern 14 gehalten und aus dem Magazin 23 über Haltenasen 24 gezogen. Beim Durchlaufen des Bogens von Punkt A nach Punkt B wird die dem Planetengetriebe 1 abgewandte Kante 35 des Zuschnitts 34 an einer Führung 25 entlang geführt, so dass sich der flache Zuschnitt 34 zu einer Hülse aufrichtet. Bevor der Saugerarm 5 Punkt B erreicht, wird der Zuschnitt 34 an eine umlaufende Transportvorrichtung 26 übergeben. Das Steuem des Vakuums der einzelnen Saugerarme 5 erfolgt mechanisch durch ein in das Stimrad 15 eingelassenes Kreisbogensegment. Die Luft wird durch Ansaugbohrungen 28, 29, 30 und eine Leitung 31 durch die Sauger 14 abgesaugt, damit der Zuschnitt 34 angesaugt wird.The suction arm 13, which is part of a pair of suction arms, moves into the area of the tip A, a blank 34 is sucked out of the magazine 23, and when leaving the Sucker arm 13 of tip A, this blank 34 is held by the suckers 14 and pulled out of the magazine 23 via retaining lugs 24. When passing through the arch From point A to point B, the edge 35 of the planetary gear 1 facing away Blank 34 guided along a guide 25 so that the flat blank 34 erects into a sleeve. Before the suction arm reaches 5 point B, the Transfer blank 34 to a rotating transport device 26. The tax of the Vacuum of the individual suction arms 5 takes place mechanically by means of a thrust wheel 15 embedded circular arc segment. The air is drawn through suction bores 28, 29, 30 and a line 31 is sucked through the suction device 14 so that the blank 34 is sucked in becomes.

Besonders vorteilhaft bei der Absaugung und Aufrichtung mit diesem System ist, dass der Zuschnitt 34 jederzeit sowohl parallel zum Magazin 23, als auch zur Transportvorrichtung 26 gehalten wird, so dass auch breitere Zuschnitte 34 problemlos verarbeitet werden können. Zusätzlich ist es von Vorteil, dass bei der Entnahme aus dem Magazin 23 fast ausschließlich eine Bewegung in Richtung des Magazins 23 ausgeführt wird, während der Zuschnitt 34 bei der Übergabe an die Transportvorrichtung 26 schon eine Bewegungskomponente in Transportrichtung hat.It is particularly advantageous for the extraction and erection with this system that the blank 34 at any time both parallel to the magazine 23, and to Transport device 26 is held, so that even wider blanks 34 easily can be processed. In addition, it is advantageous that when removing from the magazine 23 moves almost exclusively in the direction of the magazine 23 is executed while the blank 34 is transferred to the Transport device 26 already has a movement component in the transport direction.

Als weiterer Vorteil ist zu nennen, dass auf dem Rotor 6 eine beliebige Anzahl von Planeten 8 mit Saugerarmen 13 befestigt werden kann. Hierdurch ist es z. B. möglich, bei Erhöhung der Anzahl von Saugerarmpaaren 27 von drei auf vier eine 33-prozentige Leistungssteigerung zu erzielen, während die Antriebsdrehzahl und damit die Ansaug-, Aufricht- und Übergabezeit die selbe wie bei drei Saugerarmpaaren 27 ist.
