Description

Die Erfindung betrifft eine Vorrichtung für die Entnahme von flach zusammengelegten Faltschachteln aus einem Magazinschacht und deren Übergabe an einen Förderer mit jeweils eine Faltschachtel aufnehmenden Förderzellen, bestehend aus einem um eine Sonnenachse drehbaren und antreibbaren Planetenträger, einem Planetenteil, das um eine zur Sonnenachse exzentrische und mit ihr parallele Planetenachse drehbar am Planetenträger gelagert ist und ein Greiforgan sowie ein mit der Planetenachse koaxiales Planetenrad trägt, das direkt oder indirekt mit einem zur Sonnenachse koaxialen Sonnenrad gekoppelt ist. The invention relates to a device for removal of folded flat boxes from one Magazine shaft and its transfer to a conveyor conveyor cells each holding a folding box, consisting of a rotatable around a sun axis and drivable planet carrier, a planet part that around one eccentric to the sun axis and parallel to it Planet axis is rotatably mounted on the planet carrier and a gripping member and one coaxial with the planet axis Planet gear that directly or indirectly with one to Sun axis coaxial sun gear is coupled.

Derartige Vorrichtungen bilden insbesondere bei Verpackungsmaschinen das Koppelglied zwischem dem geneigt zur Vertikalen verlaufenden Magazinschacht, in dem die flach zusammengelegten Faltschachteln bereit gestellt sind, und dem Förderer mit seinen Förderzellen, in denen die aufgerichteten Faltschachteln zur weiteren Verarbeitung und Befüllung in der Verpackungsmaschine abtransportiert werden.Such devices form in particular Packaging machines inclined between the coupling link to the vertical magazine shaft in which the folded flat boxes provided and the sponsor with his funding cells, in which the erected folding boxes for further Processing and filling in the packaging machine be transported away.

Bei einer in der DE 42 24 897 C1 offenbarten Vorrichtung der eingangs genannten Art ergibt sich durch die Überlagerung der Bewegungen von dem Planetenträger und dem Planetenteil eine Hypozykloidenbahn des Greiforgans, das die Faltschachtel aus dem Magazinschacht übernimmt und an die Förderzelle übergibt. Diese Hypozykloidenbahn erfordert einen großen Platzbedarf und eine große Bahnlänge, die zu durchfahren zeitaufwendig ist, so daß an dem Planetenträger mehrere Planetenteile mit Greiforganen angeordnet sind, um die gewünschte hohe Verarbeitungsgeschwindigkeit zu erzielen. Neben dem hohen Platzbedarf und dem hohen apparativen Aufwand ist weiterhin nachteilig, daß ein hoher Zeitaufwand auch bei den häufig erforderlichen Formatwechsel nötig ist, wenn nach der Verarbeitung der Faltschachtel in einer gegebenen Größe Faltschachteln einer anderen Größe verarbeitet werden sollen, da dazu eine erneute Justierung der Vorrichtung erforderlich ist und zum Teil auch Formatteile ausgetauscht werden müssen. Der apparative Aufwand schließlich ist weiterhin erhöht, da an jedem Planetenteil drehbar um eine Drehachse ein Aufrichtorgan für die Faltschachtel gelagert, um die Faltschachtel zur Zeitersparnis bereits aufgerichtet in die Förderzelle des Förderers übergeben zu können. Das Aufrichtorgan nimmt dazu bezogen auf die Ebene des Greifers mit der Faltschachtel verschiedene Stellungen ein, während es gemeinsam mit dem Greifer die Hypozykloidenbahn durchläuft. Die Steuerung der Bewegungen des Aufrichtorgans erfolgt über ein eigenes, mit der Sonnenachse koaxiales Sonnenrad und einem eigenen, relativ zum Planetenteil drehbar um die Planetenachse gelagertes Planetenrad, wobei das Sonnenrad des Aufrichtorgans über eine Antriebseinrichtung verdrehbar ist und im Ergebnis dem Aufrichtorgan auf seiner Hypozykloidenbahn eine bestimmte Drehlage zuweisen kann.In a device disclosed in DE 42 24 897 C1 of the type mentioned above results from the Superposition of the movements of the planet carrier and the Planet part a hypocycloid orbit of the gripping organ, the takes over the folding box from the magazine shaft and on the delivery cell passes. This hypocycloid orbit requires a large amount of space and a large one Track length, which is time consuming to drive through, so that the planet carrier several planet parts with gripping organs are arranged to the desired high Achieve processing speed. In addition to the high Space requirements and the high expenditure on equipment further disadvantage that a high expenditure of time also the frequently required format change is necessary if after processing the folding box in a given Size folding boxes of a different size processed should be, since a new adjustment of the Device is required and partly also format parts need to be replaced. The expenditure on equipment after all, it is still increasing because at every part of the planet rotatable about an axis of rotation an erector for Folding box stored to the folding box Time saved already erected in the conveyor cell of the To be able to hand over the sponsor. The rising organ takes refer to the level of the gripper with the Folding box in different positions while it is together with the gripper the hypocycloid path passes. The control of the movements of the Raising body is made with its own, with the Sun axis coaxial sun gear and its own, relative to the planet part rotatably mounted about the planet axis Planetary gear, the sun gear of the erector over a drive device is rotatable and as a result the erection organ on its hypocycloid pathway can assign certain rotational position.

Die US 4 518 301 zeigt eine Vorrichtung für die Entnahme von Faltschachteln aus einem Magazinschacht und deren Übergabe an einen Förderer, wobei das Aufrichten der Faltschachteln während des Transports der Faltschachteln mittels mehrerer Greifer erfolgt, deren Drehlage durch eine Kurvenscheibe festgelegt wird.US 4,518,301 shows a device for removal of folding boxes from a magazine shaft and their Handover to a sponsor, raising the Folding boxes during transport of the folding boxes by means of several grippers, the rotational position of a cam is set.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art so auszubilden, daß ohne Beeinträchtigung der Arbeitsleistung deren Platzbedarf verringert ist.The invention is therefore based on the object Form device of the type mentioned in such a way that without affecting the work performance of them Space requirement is reduced.

Diese Aufgabe wird bei einer Vorrichtung der eingangs genannten Art nach der Erfindung dadurch gelöst, daß ohne Beeinträchtigung der Arbeitsleistung deren Platzbedarf verringert ist.This task is the beginning of a device mentioned type according to the invention in that without Impairment of work performance and space requirements is reduced.

Mit dieser Ausführungsform ist der Vorteil verbunden, daß die Bahn des Greiforgans nicht apparativ-mechanistisch vorgegeben ist, sondern aktiv durch die Antriebseinheit für das Sonnenrad beeinflußt werden kann, um gegenüber einem bloßen Ablaufen des Planetenrades an dem Sonnenrad zusätzliche Drehungen bewirken zu können, so daß bei einer bestimmten Winkelstellung des Planetenträgers dem Greiforgan eine korrespondierende Winkelstellung zugeordnet werden kann, also die Bahn des Greiforgans nicht zwingend einer Hypozykloidenbahn folgt, sondern in weiten Grenzen beeinflußbar und damit optimierbar ist, so daß die Spitzen einer Hypozykloidenbahn nicht ausgefahren werden müssen und auch ein Formatwechsel einfach durch geeignete Ansteuerung des Sonnenrades über die Antriebseinheit möglich ist. Insbesondere ist der apparative Aufwand reduziert, weil dem Planetenträger nur genau eines der Planetenteile zugeordnet ist, wobei dies ohne Reduzierung der Arbeitsleistung der Vorrichtung ermöglicht wird durch die Verkürzung der von dem Greiforgan zu durchlaufenden Bahn mit nur zwei Strecklagen für die Entnahme der Faltschachtel aus dem Magazinschacht und die Abgabe der Faltschachteln in die Förderzellen des Förderers. Da nur ein Planetenteil vorhanden ist, kann die durch den Servomotor bestimmte Drehlage des Sonnenrades genau auf das Greiforgan abgestimmt sein, so daß insbesondere keine symmetrische Bahn des Greiforgans durchlaufen werden muß, wie dies VorrausSetzung wäre bei der Verwendung einer größeren Anzahl im Planetenträger gelagerter Planetenteile.This embodiment has the advantage that the path of the gripping organ is not apparatus-mechanistic is specified, but actively by the drive unit for the sun gear can be influenced to a mere running of the planet gear on the sun gear to be able to effect additional rotations, so that at one certain angular position of the planet carrier Gripping organ a corresponding angular position can be assigned, i.e. the path of the gripping member does not necessarily follow a hypocycloid pathway, but in wide limits can be influenced and thus optimized, so that the tips of a hypocycloid trajectory are not extended have to be and a format change simply by suitable control of the sun gear via the Drive unit is possible. In particular, the apparatus expenditure is reduced because the planet carrier only exactly one of the planet parts is assigned, this being without reducing the performance of the device is made possible by shortening the Gripping device for continuous web with only two stretching positions for removing the folding box from the magazine shaft and the delivery of the folding boxes into the conveyor cells of the Conveyor. Since there is only one planet part, the rotational position of the sun gear determined by the servo motor be precisely matched to the gripping member, so that in particular, no symmetrical path of the gripping member must be run through as this would be a prerequisite for the use of a larger number in the planet carrier stored planet parts.

Im Rahmen der Erfindung ist es möglich, daß die Antriebseinheit durch ein Schrittschaltgetriebe gebildet ist. Zum Zwecke einer größeren Flexibilität ist es aber bevorzugt, wenn die Antriebseinheit durch einen Servomotor gebildet ist, der ohne feste mechanische Vorgaben, wie diese bei einem Schrittschaltgetriebe existieren, die Drehlage des Sonnenrades in beliebigen Schritten und mit beliebiger Geschwindigkeit verändern kann, daß also der Servomotor zur schrittweisen Beeinflussung der Drehlage des Planetenteils vorgesehen ist.In the context of the invention it is possible that the Drive unit formed by a stepping gear is. For the sake of greater flexibility, however, it is preferred if the drive unit by a servo motor is formed, without fixed mechanical specifications, such as these exist in a stepper transmission that Rotation of the sun gear in any steps and with any speed can change, that is Servo motor for gradually influencing the rotational position the planet part is provided.

Zweckmäßigerweise schließen die beiden Strecklagen einen Winkel von 120° miteinander ein, um so zu berücksichtigen, daß der Magazinschacht geneigt zur Vertikalen ausgerichtet ist, damit unter der Wirkung der Schwerkraft der Stapel der Faltschachteln gegen die Magazinschachtmündung gepreßt wird.The two stretching layers expediently include one Angles of 120 ° with each other so as to take into account that the magazine slot is inclined to the vertical is so under the effect of gravity the stack of the folding boxes pressed against the magazine shaft mouth becomes.

Eine ganz besonders bevorzugte Ausführungsform der Erfindung ist dadurch gekennzeichnet, daß jede Förderzelle aus mindestens einem schiebenden Mitnehmer und einem voranlaufenden Mitnehmer gebildet ist, und daß die mittels der Drehung des Sonnenrades bestimmte Bahn der Faltschachtel diese zum Aufrichten gegen den schiebenden Mitnehmer führt. Bei dieser Vorrichtung ist besonders vorteilhaft, daß unabhängig von dem Format der Faltschachtel mit der geeignet gestalteten Bahn die Aufrichtung durch den schiebenden Mitnehmer erfolgt, also kein zusätzlicher apparativer Aufwand erforderlich ist, um während des Durchlaufens der Bahn durch das Greiforgan zugleich auch die Faltschachtel aufzurichten. Günstig ist weiterhin, wenn jede Förderzelle aus mindestens einem schiebenden und einem voranlaufenden Mitnehmer gebildet ist, und wenn die mittels der Drehung des Sonnenrades bestimmte Bahn der different öffnenden Faltschachtel diese zum Aufrichten gegen den voranlaufenden Mitnehmer führt, so daß durch die gezielte Beeinflussung der Drehlage des Sonnenrades der weitere Vorteil erzielt ist, daß auch different öffnende Faltschachteln, bei denen also die durch den Mitnehmer zu beaufschlagende Seitenlasche in Förderrichtung des Förderers abgeknickt ist, aufgerichtet werden können durch Führung der Bahn des Greiforgans gegen den voranlaufenden Mitnehmer.A very particularly preferred embodiment of the Invention is characterized in that each conveyor cell from at least one pushing driver and one leading driver is formed, and that the means the rotation of the sun gear Folding box to erect against the pushing Carrier leads. This device is special advantageous that regardless of the format of the Folding box with the suitably designed web Erection is done by the pushing driver no additional equipment is required to during the passage of the web through the gripping member erect the folding box at the same time. Is cheap continue if each production cell consists of at least one pushing and a leading driver formed and if that is by means of the rotation of the sun gear certain path of the differently opening folding box this leads to standing up against the leading driver, so that by specifically influencing the rotational position of the Sun gear the other advantage is that too different opening folding boxes, so the side flap to be loaded by the driver The conveying direction of the conveyor is kinked, erected can be countered by guiding the path of the gripping organ the leading driver.

Durch die dem Sonnenrad zugeordnete Antriebseinheit können der Drehwinkel, die Drehgeschwindigkeit und der Drehsinn frei gewählt werden, wobei es aber im Sinne einer geringeren Belastung der Antriebseinheit bevorzugt ist, wenn der Drehsinn für die Drehung des Sonnenrades konstant ist und lediglich die Drehgeschwindigkeit sowie die Drehwinkel beeinflußt werden.Through the drive unit assigned to the sun gear the angle of rotation, the speed of rotation and the direction of rotation can be chosen freely, but in the sense of a lower load on the drive unit is preferred, when the direction of rotation for the rotation of the sun gear is constant is and only the speed of rotation and the Angle of rotation can be influenced.

Die in der Zeichnung dargestellte Vorrichtung 1 dient der Entnahme von flach zusammengelegten Faltschachteln 2 aus einem gegenüber der Vertikalen geneigten Magazinschacht 3, wobei die Faltschachtel 2 nach der Entnahme zu einem Förderer 4 transportiert wird, der mehrere Förderzellen 5 aufweist, die durch schiebende Mitnehmer 6 und durch vorauslaufende Mitnehmner 7 gebildet sind, die zwischen sich die während der Übergabe aufgerichtete Faltschachtel 2 aufnehmen. The device 1 shown in the drawing serves the Removal of folded flat boxes 2 from a magazine shaft 3 inclined to the vertical, the folding box 2 after removal into one Conveyor 4 is transported, the multiple conveyor cells 5th has that by pushing driver 6 and by leading drivers 7 are formed between upright during the handover Pick up folding box 2.

Die Vorrichtung 1 weist einen um eine Sonnenachse 8 drehbaren und antreibbaren Planetenträger 9 auf, in dem ein um eine zur Sonnenachse 8 exzentrische und zu ihr parallele Planetenachse 10 drehbares Planetenteil 11 gelagert ist, das an seinem freien Ende ein Greiforgan 12 zum Ergreifen der Faltschachtel 2 aufweist sowie ein mit der Planetenachse 10 koaxiales Planetenrad 13 trägt, das mit einem zur Sonnenachse 8 koaxialen Sonnenrad 14 gekoppelt ist, wobei in dem in der Zeichnung dargestellten Ausführungsbeispiel die Kopplung direkt über einen Treibriemen 15 erfolgt, aber auch indirekt über ein Zwischenrad realisiert sein kann. Zur gezielten Beeinflussung der Drehlage des Planetenteils 11 ist dem Sonnenrad 14 eine Antriebseinheit 16 zugeordnet, die durch einen Servomotor realisiert ist, mit dem der Drehsinn, der Drehwinkel sowie die Drehgeschwindigkeit des Sonnenrades 14 verändert werden können, so daß die durch die Drehung des Planetenträgers 9 verursachte Drehung des Planetenteiles 11 zusätzlich durch die Drehung des Sonnenerades 14 überlagert wird, um so in weiten Grenzen die Bahn des Greiforgans 12 gezielt zu gestalten und in dem Sinne zu optimieren, daß die Spitzen einer Hypozykloidenbahn nicht ausgefahren werden müssen, sondern eine Verkürzung der Bahn des Greiforgans 12 eintritt mit der damit verbundenen Reduzierung des Raumbedarfes und der Zeit für einen Bahnumlauf. Die Figuren 2 bis 9 zeigen schematisch einen vollen Umlauf des Greiforgans 12, das sich in Richtung des Pfeiles G um die Planetenachse 10 des Planetenrades 13 dreht, während der Planetenträger 9 sich in Richtung P um die Sonnenachse 8 dreht. Durch die Verdrehung des Sonnenrades 14 mittels des Servomotors folgt die Bahn des Greiforgans 12 der in den Figuren 2 bis 9 dargestellten Trajektorie 17, die sich durch ihre Kürze auszeichnet. Diese Trajektorie 17 ist asymmetrisch, so daß dem Planetenträger 9 nur eines der Planetenteile 11 zugeordnet ist, wobei die Bahn des Greiforgans 12 zwei in den Figuren 2 und 8 dargestellte Strecklagen 18 aufweist, die einen Winkel von 120° miteinander einschließen. In dem in den Figuren 2 bis 9 dargestellten Zyklus erfolgt das Aufrichten der aus dem Magazinschacht 3 durch das Greiforgan 12 entnommenen Faltschachtel 2 durch deren Anlage an dem schiebenden Mitnehmer 6 der Förderzelle 5, wobei durch die Antriebseinheit 16 allerdings auch die Bahn so gestaltet werden kann, daß eine different öffnende Faltschachtel 2 gegen den voranlaufenden Mitnehmer 7 geführt wird, um so die in Förderrichtung des Förderers 4 voranstehende Seitenlasche abzuknicken.The device 1 has one about a sun axis 8 rotatable and drivable planet carrier 9, in which one eccentric to the sun axis 8 and to it parallel planet axis 10 rotatable planet part 11 is mounted, which has a gripping member 12 at its free end for grasping the folding box 2 and one with the planetary axis 10 carries coaxial planet gear 13 that with a sun gear 14 coaxial with the sun axis 8 is coupled, in which shown in the drawing Embodiment coupling directly via a Driving belt 15 takes place, but also indirectly via a Intermediate wheel can be realized. For targeted Influencing the rotational position of the planetary part 11 is the Sun gear 14 assigned a drive unit 16 by a servo motor is realized with which the direction of rotation, the Angle of rotation and the speed of rotation of the Sun gear 14 can be changed so that by the rotation of the planet carrier 9 causes rotation of the Planet part 11 additionally by the rotation of the Sonnenerades 14 is superimposed, so within wide limits to design the path of the gripping member 12 specifically and in to optimize the sense that the tips of a Hypocycloidal path does not have to be extended, but a shortening of the path of the gripping member 12 occurs with the associated reduction in space requirements and Time for a rail orbit. Figures 2 to 9 show schematically a full revolution of the gripping member 12, the itself in the direction of arrow G around the planet axis 10 of the Planetary gear 13 rotates while the planet carrier 9 is rotating rotates in the direction P around the sun axis 8. Through the Rotation of the sun gear 14 by means of the servo motor the path of the gripping member 12 follows that in FIGS 9 shown trajectory 17, which is characterized by its brevity distinguished. This trajectory 17 is asymmetrical, so that the planet carrier 9 only one of the planet parts 11 is assigned, the path of the gripping member 12 two in 2 and 8 have stretching positions 18 shown, that enclose an angle of 120 °. By doing this is done in FIGS. 2 to 9 Erecting from the magazine shaft 3 through the Gripping member 12 removed folding box 2 by their System on the pushing driver 6 of the feed cell 5, whereby the drive unit 16 also Path can be designed so that a different opening Folding box 2 against the leading driver 7 is guided so that in the conveying direction of the conveyor 4th to bend the above side flap.
