Weiterhin betrifft die Erfindung eine entsprechende Vorrichtung.The invention relates to a method for handling bundles bundled bags, in particular Wicket bags, and for feeding the bag to a packaging machine. Furthermore, the invention relates to a corresponding device.

Insbesondere bei der Verpackung von Hygieneprodukten, wie Windeln oder Damenbinden, werden die Produkte in sogenannten Wicket-Beuteln verpackt. Derartige Beutel zeichnen sich dadurch aus, dass die Beutel in einem oberen Bereich Löcher zur Handhabung der Beutel aufweisen. Derartige Beutel und geeignete Handhabungsvorrichtungen sind in EP 1 157 815 A2 , DE 197 13 334 C1 und DE 195 21 852 A1 beschrieben. DE 197 13334 C1 offenbart ein Verfahren bzw. eine Vorrichtung zum Handhaben von in Bündeln zusammengefassten Beuteln, und zum Zuführen der Beutel zu einer Verpackungsmaschine, wobei die Beutel in mehreren Bündeln in einem der Verpackungsmaschine vorgeordneten Magazin bereitgestellt werden, wobei die Bündel jeweils derart auf Beutelträgern angeordnet sind, dass sich die Beutelträger durch Aufhängelöcher der Beutel erstrecken, wobei die Beutelträger mit den daran befindlichen Beuteln aus dem Magazin der Verpackungsmaschine zugeführt werden, die Bündel von den Beutelträgern unmittelbar einer taktweise angetriebenen Fördereinrichtung der Verpackungsmaschine übergeben werden, und nachfolgend in der Verpackungsmaschine befüllt werden. DE195 21 852 A1 offenbart ein Verfahren bzw. eine Vorrichtung zum Handhaben von in Bündeln zusammengefassten Beuteln und zum Zuführen der Beutel zu einer Verpackungsmaschine, wobei die Beutel in mehreren Bündeln in einem der Verpackungsmaschine vorgeordneten Magazin bereitgestellt werden, wobei die Bündel an Beutelhaltern des Magazins angeordnet sind, wobei die Beutel an den Beutelhaltern des Magazins nacheinander durch entsprechende Relativbewegung des Magazins zur Übergabe an einen Zuführförderer bereitgehalten werden, der die Beutel an Aufnahmestifte einer taktweise angetriebenen Fördereinrichtung der Verpackungsmaschine übergibt, in der nachfolgend die Beutel befüllt werden. In der Praxis werden Bündel aus Beuteln nacheinander manuell durch einen Bediener einer Verpackungsmaschine zugeführt. Dabei können die Bündel beispielsweise mit den Löchern der Beutel auf Aufnahmestifte eines Förderers der Verpackungsmaschine aufgesteckt werden.In particular, in the packaging of hygiene products, such as diapers or sanitary napkins, the products are packed in so-called wicket bags. Such bags are characterized in that the bags have in an upper area holes for handling the bag. Such bags and suitable handling devices are in EP 1 157 815 A2 . DE 197 13 334 C1 and DE 195 21 852 A1 described. DE 197 13334 C1 discloses a method and apparatus for handling bags bundled in bundles, and for feeding the bags to a packaging machine, wherein the bags are provided in a plurality of bundles in a magazine upstream of the packaging machine, the bundles being respectively disposed on bag carriers the bag carriers extend through bag hanging holes, the bag carriers with the bags thereon being fed from the magazine to the packaging machine, the bundles being transferred directly from the bag carriers to a cyclically driven conveyor of the packaging machine, and subsequently being filled in the packaging machine. DE195 21 852 A1 discloses a method and apparatus for handling bags bundled in bundles and for feeding the bags to a packaging machine, the bags being provided in a plurality of bundles in a magazine upstream of the packaging machine, the bundles being disposed on bag holders of the magazine; Pouch be held on the bag holders of the magazine successively by corresponding relative movement of the magazine for transfer to a feed conveyor, which passes the bags to receiving pins of a cyclically driven conveyor of the packaging machine, in which subsequently the bags are filled. In practice, bundles of bags are successively fed manually by an operator to a packaging machine. The bundles can be plugged, for example with the holes of the bag on receiving pins of a conveyor of the packaging machine.

Ein Nachteil dieser Vorgehensweise besteht darin, dass bei einer manuellen Zufuhr der Bündel die Geschwindigkeit der Verpackungsmaschine begrenzt ist. Der Bediener kann die Bündel nämlich nur während eines kurzzeitigen Stillstands des entsprechenden Förderers auflegen. Bei entsprechend hohen Produktionsgeschwindigkeiten der Verpackungsmaschine ist die Stillstandszeit des Förderers entsprechend kurz, sodass der Bediener schnell an die Grenzen seiner Leistungsfähigkeit kommt.A disadvantage of this approach is that with a manual feed of the bundles, the speed of the packaging machine is limited. The operator can only do the bundles during a brief standstill of the corresponding Hang up conveyor. At correspondingly high production speeds of the packaging machine, the downtime of the conveyor is correspondingly short, so that the operator quickly reaches the limits of its performance.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde Verfahren und Vorrichtungen der eingangs genannten Art zur Verfügung zu stellen, die eine ordnungsgemäße Zufuhr der Beutel auch bei hohen Produktionsgeschwindigkeiten der Verpackungsmaschine gewährleisten.Proceeding from this, the present invention seeks to provide methods and apparatus of the type mentioned above, the one ensure proper feeding of the bags even at high production speeds of the packaging machine.

Die in den Figuren gezeigten Ausführungsbeispiele der Erfindung beziehen sich auf die Handhabung von Beuteln 10 im Zusammenhang mit der Zuführung zu einer Verpackungsmaschine 11.The embodiments of the invention shown in the figures relate to the handling of bags 10 in connection with the supply to a packaging machine 11.

Bei den Beuteln 10 handelt es sich im vorliegenden Fall um sogenannte Wicket-Beutel. Charakteristisches Merkmal dieser Beutel 10 sind Aufhängelöcher 12 im Bereich eines oberen Randes der Beutel 10. Derartige Beutel 10 werden bevorzugt bei der Verpackung von Hygieneprodukten eingesetzt. Die Beutel 10 können aber auch in anderen Bereichen zum Einsatz kommen, beispielsweise bei der Verpackung von (Toast-)Brot.The bags 10 in the present case are so-called wicket bags. Characteristic feature of these bags 10 are hanging holes 12 in the region of an upper edge of the bag 10. Such bags 10 are preferably used in the packaging of hygiene products. The bags 10 can also be used in other areas, for example in the packaging of (toast) bread.

Die Beutel 10 sind aus einem Verpackungsmaterial gebildet. Insbesondere kommen folienartige Verpackungsmaterialien zum Einsatz, wie zum Beispiel Polyethylenfolien oder Polypropylenfolien.The bags 10 are formed from a packaging material. In particular, sheet-like packaging materials are used, such as polyethylene films or polypropylene films.

Die Verarbeitung der Beutel 10 erfolgt gruppiert, wobei die Beutel 10 zu Bündeln 13 zusammengefasst gehandhabt werden. Jedes Bündel 13 umfasst eine Mehrzahl von Beuteln 10, beispielsweise fünf Stück, zehn Stück oder dergleichen. Innerhalb des Bündels 13 liegen die Beutel 10 flach aneinander an als regelmäßiger Stapel.The processing of the bag 10 is grouped, the bags 10 are handled combined into bundles 13. Each bundle 13 comprises a plurality of bags 10, for example five pieces, ten pieces or the like. Within the bundle 13, the bags 10 lie flat against each other as a regular stack.

Die Bündel 13 werden in einem Magazin 14 bereitgestellt und der Verpackungsmaschine 11 automatisch zugeführt. Hierzu im Einzelnen:The bundles 13 are provided in a magazine 14 and automatically fed to the packaging machine 11. In detail:

Im ersten Ausführungsbeispiel gemäß Fig. 1 bis 13 erfolgt die Bereitstellung der Bündel 13 auf sogenannten Beutelträgern 15, die durch die Aufhängelöcher 12 der Beutel 10 greifen und an denen die Beutel 10 hängend transportiert werden.In the first embodiment according to Fig. 1 to 13 the provision of the bundles 13 takes place on so-called bag carriers 15 which reach through the hanging holes 12 of the bags 10 and on which the bags 10 are transported suspended.

Im vorliegenden Fall weisen die Beutelträger 15 eine hakenförmige Gestalt auf mit einem freien Ende 16, das durch die Aufhängelöcher 12 hindurchgeführt wird zur Aufnahme der Beutel 10. Grundsätzlich kann die Gestalt der Beutelträger 15 natürlich abweichend sein. Hierzu wird auch auf das zweite Ausführungsbeispiel verwiesen.In the present case, the bag carrier 15 has a hook-like shape with a free end 16 which is passed through the suspension holes 12 for receiving the bag 10. Basically, the shape of the bag carrier 15 may of course be different. Reference is also made to the second embodiment.

Im vorliegenden Fall weist jeder Beutel 10 zwei voneinander beabstandete Aufhängelöcher 12 auf. Dementsprechend werden die Beutel 10 von zwei Beutelträgern 15 gehalten, die in einem entsprechenden Abstand zueinander angeordnet sind. Es ist denkbar, dass die Beutel 10 auch eine geringere oder größere Anzahl an Aufhängelöchern 12 aufweisen können, so dass die Anzahl der Beutelträger 15 entsprechend variieren kann. Denkbar sind auch speziell geformte Aufhängelöcher 12 mit entsprechend angepassten Querschnitten der Beutelträger 15, so dass bei Einsatz lediglich eines Beutelträgers 15 ein seitliches Pendeln der Beutel 10 vermieden werden kann. Demnach ist die Anzahl und Gestalt der Beutellöcher 10 für die vorliegende Erfindung nicht von entscheidender Bedeutung.In the present case, each bag 10 has two spaced suspension holes 12. Accordingly, the bags 10 are held by two bag carriers 15, which are arranged at a corresponding distance from one another. It is conceivable that the bags 10 may also have a smaller or larger number of hanging holes 12, so that the number of bag carriers 15 may vary accordingly. Also conceivable are specially shaped hanging holes 12 with correspondingly adapted cross sections of the bag carriers 15, so that when only one bag carrier 15 is used, a lateral oscillation of the bags 10 is avoided can. Thus, the number and shape of the bag holes 10 is not critical to the present invention.

Im vorliegenden Ausführungsbeispiel kommen lediglich beispielhaft zwei Beutelträger 15 zur Aufnahme eines Bündels 13 zum Einsatz. Die beiden Beutelträger 15 sind mit Abstand zueinander an einer Achse 17 angeordnet, die über seitliche Laufrollen 18 an zwei Laufschienen 19 als Führungsmittel verfahrbar gelagert ist. Laufrollen 18, Achse 17 und die Beutelträger 15 sind Teil eines Laufwagens 20, der an dem Führungsmittel verfahrbar angeordnet ist.In the present exemplary embodiment, only two bag carriers 15 for receiving a bundle 13 are used by way of example. The two bag carriers 15 are arranged at a distance from each other on an axis 17, which is mounted on lateral rails 18 on two rails 19 as a guide means movable. Casters 18, axis 17 and the bag carrier 15 are part of a carriage 20 which is arranged to be movable on the guide means.

Die beiden Laufschienen 19 verlaufen seitlich mit Abstand zur Förderbahn der Bündel 13. Im vorliegenden Fall verfügen die Laufschienen 19 über eine gekrümmte Anlagefläche für die Laufrollen 18. Entsprechend sind die Laufrollen 18 konvex ausgebildet, so dass die Laufrollen 18 entlang der Laufschienen 19 geführt werden. Selbstverständlich können auch andere Maßnahmen zur Ausrichtung und Führung der Achse 17 quer zur Transportrichtung der Beutel 10 getroffen werden.In the present case, the rails 19 have a curved contact surface for the rollers 18. Accordingly, the rollers 18 are convex, so that the rollers 18 are guided along the rails 19. Of course, other measures for alignment and guidance of the axis 17 transverse to the transport direction of the bag 10 can be made.

Die Bereitstellung der Bündel 13 im Magazin 14 kann dadurch erfolgen, dass ein Bediener eine Gruppe von Beuteln 10 auf die Beutelträger 15 hängt und den Laufwagen 20 dann auf die Führungsschienen 19 setzt.The provision of the bundles 13 in the magazine 14 can be effected by an operator hanging a group of bags 10 on the bag carriers 15 and then placing the carriage 20 on the guide rails 19.

Alternativ ist es denkbar, dass bereits an den Beutelträgern 15 hängende Beutel 10 dem Magazin 14 zugeliefert werden beispielsweise von einem (externen) Zulieferer.Alternatively, it is conceivable that bags 10 which are already hanging on the bag carriers 15 are delivered to the magazine 14, for example by an (external) supplier.

In einem ersten Abschnitt der Förderstrecke der Bündel 13 erfolgt die Zuführung in Richtung der Verpackungsmaschine 11 (ausschließlich) durch Schwerkraft. Die Laufschienen 19 sind hierzu in Richtung der Verpackungsmaschine 11 abwärts geneigt angeordnet, so dass die Laufwagen 20 in Richtung der Verpackungsmaschine 11 rollen.In a first section of the conveying path of the bundles 13, the supply in the direction of the packaging machine 11 takes place (exclusively) by gravity. The rails 19 are arranged inclined downwards in the direction of the packaging machine 11 so that the carriages 20 roll in the direction of the packaging machine 11.

Dieser erste Abschnitt der Förderstrecke wird begrenzt durch eine Vereinzelungseinrichtung 21. Vor der Vereinzelungseinrichtung 21 werden die Laufwagen 20 aufgestaut bzw. in Dichtlage transportiert. Im Anschluss an die Vereinzelungseinrichtung 21 werden die Laufwagen 20 in einem zweiten Abschnitt der Förderstrecke einzeln durch ein Förderorgan erfasst und in Richtung der Verpackungsmaschine 11 transportiert. Hierzu im Einzelnen:
Die Vereinzelungseinrichtung 21 ist nach Art einer Schleuse konstruiert, mit zwei Haltemitteln 22, 23 für die Laufwagen 20. Die beiden Haltemittel 22. 23 sind unabhängig voneinander in den Förderweg der Laufwagen 20 hinein- und herausbewegbar, im vorliegenden Fall in vertikaler Richtung. Hinter dem ersten Haltemittel 22 werden die Laufwagen 20 aufgestaut. Durch Anheben und Absenken des ersten Haltemittels 22 wird ein einzelner Laufwagen 20 durchgelassen und stößt gegen das abgesenkte Haltemittel 23. Dort wird der Laufwagen 20 dann positionsgenau von einer Fördereinrichtung 29 erfasst, unter gleichzeitigem Anheben des zweiten Haltemittels 23 und Transport des Laufwagens 20 in Richtung der Verpackungsmaschine.
This first section of the conveying path is limited by a separating device 21. Before the separating device 21, the carriages 20 are dammed or transported in a sealing position. Subsequent to the separating device 21, the carriages 20 are detected individually in a second section of the conveying path by a conveying member and transported in the direction of the packaging machine 11. In detail:
The separating device 21 is constructed in the manner of a lock, with two holding means 22, 23 for the carriages 20. The two holding means 22, 23 are independently movable into and out of the conveying path of the carriages 20, in the present case in the vertical direction. Behind the first holding means 22, the carriage 20 are dammed. By lifting and lowering the first holding means 22, a single carriage 20 is passed and abuts against the lowered holding means 23. There, the carriage 20 is then accurately detected by a conveyor 29, with simultaneous lifting of the second holding means 23 and transport of the carriage 20 in the direction of packaging machine.

Das Anheben und Absenken der Haltemittel 22, 23 erfolgt beispielsweise durch entsprechende Pneumatikzylinder oder andere geeignete Organe. Es versteht sich, dass die Haltemittel 22, 23 nicht zwingend in vertikaler Richtung bewegbar sein müssen und entsprechend geeignete Vereinzelungsvorrichtungen anderer Art bzw. Konstruktion an dieser Stelle ebenfalls denkbar sind.The raising and lowering of the holding means 22, 23 takes place, for example, by corresponding pneumatic cylinders or other suitable organs. It is understood that the holding means 22, 23 does not necessarily have to be movable in the vertical direction and correspondingly suitable separating devices of a different kind or construction are also conceivable at this point.

Das bereits angesprochene Förderorgan zum weiteren Transport der vereinzelten Laufwagen 20 wird im vorliegenden Fall durch zwei taktweise angetriebene Mitnehmerketten 26 gebildet. Die Mitnehmerketten 26 sind jeweils über Umlenkrollen 27 geführt, wobei ein Fördertrum parallel zur Laufschiene 19 zur Zuführung der Laufwagen 20 in Richtung der Verpackungsmaschine 11 verläuft. Das Fördertrum ist mit Abstand oberhalb der Laufschienen 19 angeordnet, so dass die gegenüber den Mitnehmerketten 26 nach außen abstehenden Mitnehmer 25 jeweils einen Laufwagen 20 erfassen und entlang des weiteren Verlaufs der Förderstrecke transportieren können.The already mentioned conveying member for further transport of the separated carriage 20 is formed in the present case by two cyclically driven driving chains 26. The driver chains 26 are each guided over deflection rollers 27, wherein a conveying run runs parallel to the running rail 19 for feeding the carriage 20 in the direction of the packaging machine 11. The conveying strand is arranged at a distance above the rails 19, so that the driver 25 protruding outward relative to the driver chains 26 can each detect a carriage 20 and transport it along the further course of the conveyor line.

Die Mitnehmer 25 können entweder eine Ausnehmung zum Eingriff mit einer Achse 17 eines Laufwagens 20 aufweisen oder als Mitnehmerpaar in entsprechendem Abstand angeordnet sein, so dass zwischen den beiden Mitnehmern des Mitnehmerpaares die Achse 17 erfasst bzw. eingeklemmt und transportiert werden kann. Wie Fig. 3 zeigt, sind die Mitnehmerketten 26 jeweils innenseitig der Laufschienen 19 angeordnet, wobei die Mitnehmer 25 wiederum seitlich innenseitig an den Mitnehmerketten 26 angeordnet sind und die Achse 17 des Laufwagens 20 mit größtmöglichem Abstand zueinander erfassen.The driver 25 may either have a recess for engagement with an axle 17 of a carriage 20 or be arranged as a driver pair at a corresponding distance, so that between the two drivers of the driver pair, the axis 17 detected or clamped and can be transported. As Fig. 3 shows, the carrier chains 26 are each arranged on the inside of the rails 19, wherein the drivers 25 are in turn laterally arranged on the inside of the driver chains 26 and the axis 17 of the carriage 20 with the greatest possible distance from each other.

Es versteht sich, dass alternativ zu den Mitnehmerketten 26 auch andere (Endlos-)Förderer zum Einsatz kommen können.It is understood that as an alternative to the drive chains 26, other (endless) conveyor can be used.

Nachfolgend werden die Laufwagen 20 bzw. die Bündel 13 der Verpackungsmaschine 11 der weiteren Verarbeitung zugeführt. Im vorliegenden Fall erfolgt dies durch Zuführung der Bündel 13 zu einer Fördereinrichtung 29, die die Bündel 13 dem Verpackungsvorgang zuführt. Bei der Fördereinrichtung 29 handelt es sich um einen Teil der Verpackungsmaschine 11. Die Fördereinrichtung 29 weist Aufnahmestifte 28 auf, die entsprechend der Anzahl und Anordnung der Aufhängelöcher 12 vorgesehen sind. Im vorliegenden Fall sind die Aufnahmestifte 28 paarweise angeordnet, wobei der Abstand zwischen den Aufnahmestiften 28 dem Abstand der Aufhängelöcher 12 der Beutel 10 entspricht. Mehrere solcher Aufnahmestiftpaare sind mit Abstand zueinander am Umfang eines Endlosförderers, vorzugsweise eines endlosen Riemenförderers angeordnet, gegenüber dem die Aufnahmestifte 28 in Art von Mitnehmern abstehen. Die Zuführung der Bündel 13 erfolgt dabei im Bereich eines Obertrums des Riemenförderers. Genauer gesagt erfolgt die Zufuhr der Bündel 13 an ein Paar von Aufnahmestiften 28 während eines kurzzeitigen Stillstands der taktweise angetriebenen Fördereinrichtung 29.Subsequently, the carriages 20 and the bundles 13 of the packaging machine 11 are supplied for further processing. In the present case, this is done by feeding the bundles 13 to a conveyor 29, which supplies the bundles 13 to the packaging process. The conveyor 29 is a part of the packaging machine 11. The conveyor 29 has receiving pins 28, which are provided according to the number and arrangement of the suspension holes 12. In the present case, the receiving pins 28 are arranged in pairs, wherein the distance between the receiving pins 28 corresponds to the distance of the suspension holes 12 of the bag 10. Several such pairs of receiving pin are spaced from each other on the circumference of an endless conveyor, preferably an endless belt conveyor, against which the receiving pins 28 protrude in the form of drivers. The supply of the bundles 13 takes place in the region of an upper strand of the belt conveyor. More specifically, the supply of the bundles 13 to a pair of receiving pins 28 occurs during a momentary stoppage of the cyclically driven conveyor 29.

Mit Hilfe der Fördereinrichtung 29 werden die Bündel 13 quer zur Förderrichtung auf den Laufschienen 19 transportiert und in den Bereich einer Befüllstation 30 der Verpackungsmaschine 11 verbracht. Dort werden in aus dem Stand der Technik bekannter Weise Produkte 31, beispielsweise Windeln, in die Beutel 10 verpackt und quer zur Förderrichtung der Bündel 13 auf der Fördereinrichtung 29 abtransportiert.With the aid of the conveyor 29, the bundles 13 are transported transversely to the conveying direction on the rails 19 and spent in the region of a filling station 30 of the packaging machine 11. There, in a manner known from the prior art, products 31, for example diapers, are packed in the pouches 10 and conveyed away transversely to the conveying direction of the bundles 13 on the conveying device 29.

Im Bereich einer Zuführstation 32 der Fördereinrichtung 29 werden die Bündel 13 von den Beutelträgern 15 unmittelbar an die Aufnahmestifte 28 der Fördereinrichtung 29 übergeben. Dies erfolgt indem die freien Enden der Beutelträger 15 fluchtend mit den freien Enden der Aufnahmestifte 28 angeordnet werden, so dass die Beutel 10 auf die Aufnahmestifte 28 herabfallen können. Um diese Übergabe geordnet durchführen zu können, sind folgende weitere Mittel und Maßnahmen vorgesehen:
Im Bereich der Zuführstation 32 sind Schwenkarme 33 vorgesehen, die um eine vertikale Achse 34 mittels eines pneumatischen Drehzylinders 35 verschwenkbar sind. Die Schwenkarme 33 sind oberseitig als plattenförmige Organe ausgebildet zur Bildung einer Auflagefläche für ein Bündel 13 in der Zuführstation 32.
In the area of a feed station 32 of the conveyor 29, the bundles 13 are transferred from the bag carriers 15 directly to the receiving pins 28 of the conveyor 29. This is done by locating the free ends of the bag carriers 15 in alignment with the free ends of the locating pins 28 so that the pouches 10 can fall down onto the locating pins 28. In order to carry out this transfer in an orderly manner, the following additional means and measures are provided:
In the region of the feed station 32 pivot arms 33 are provided, which are pivotable about a vertical axis 34 by means of a pneumatic rotary cylinder 35. The pivot arms 33 are formed on the upper side as plate-shaped members to form a support surface for a bundle 13 in the feed station 32nd

Bei der Zuführung der Bündel 13 werden die Laufwagen 20 durch die Mitnehmer 25 gefördert, bis die freien Enden 16 der Beutelträger 15 auf den Aufnahmestiften 28 liegen. Danach werden die Schwenkarme 33 seitlich weggeschwenkt, so dass das Bündel 13 durch die Aufnahmestifte 28 aufgenommen wird.When the bundles 13 are fed, the carriages 20 are conveyed by the carriers 25 until the free ends 16 of the bag carriers 15 lie on the receiving pins 28. Thereafter, the pivot arms 33 are laterally pivoted away, so that the bundle 13 is received by the receiving pins 28.

Als weitere Besonderheit ist vorgesehen, dass die Beutelträger 15 um die Achse 17 des Laufwagens 20 gedreht werden, um das freie Ende 16 der Beutelträger 15 oberhalb der bzw. auf den Aufnahmestiften 28 zu platzieren. Hierzu sind in den Schwenkarmen 33 nutenförmige Vertiefungen 36 ausgebildet. Die Vertiefungen 36 dienen zum einen der Führung der Beutelträger 15. Zum anderen weisen die Vertiefungen 36 einen geneigten Boden 37 auf, der in Richtung der Aufnahmestifte 28 ansteigt. Wie Fig. 7 bis 9 zeigen, gelangt das freie Ende 16 der Beutelträger 15 in Kontakt mit dem Boden 37 der Vertiefung 36 und wird entlang des ansteigenden Bodens 37 geführt, wodurch der Beutelträger 15 während des Transports in Förderrichtung gedreht wird bis das freie Ende 16 derselben nach unten weist und auf einem Aufnahmestift 28 ruht.As a further special feature, it is provided that the bag carriers 15 are rotated about the axis 17 of the carriage 20 in order to place the free end 16 of the bag carrier 15 above or on the receiving pins 28. For this purpose, 33 groove-shaped recesses 36 are formed in the pivot arms. On the one hand, the depressions 36 have an inclined bottom 37, which rises in the direction of the receiving pins 28. As Fig. 7 to 9 show, the free end 16 of the bag carrier 15 comes into contact with the bottom 37 of the recess 36 and is guided along the rising bottom 37, whereby the bag carrier 15 is rotated during transport in the conveying direction until the free end 16 thereof facing downward and on a recording pin 28 rests.

Durch das Verschwenken der Schwenkarme 33 aus dem Bereich oberhalb der Fördereinrichtung 29 können die Beutel 10 des Bündels 13 auf die Aufnahmestifte 28 herabfallen. Die Beutel 10 ruhen dann auf einer horizontalen Transportbahn 38, die mit Abstand oberhalb der Fördereinrichtung 29 angeordnet ist und entlang derer die Beutel 10 in Förderrichtung der Fördereinrichtung 29 transportiert werden. Die Transportbahn 38 weist einen Längsschnitt 39 auf durch den die Aufnahmestifte 28 hindurchtreten, um die Beutel 10 aufzunehmen. Der Längsschnitt 39 verläuft parallel zur Förderrichtung auf der Fördereinrichtung 29.By pivoting the pivot arms 33 out of the region above the conveyor 29, the bags 10 of the bundle 13 can fall onto the receiving pins 28. The bags 10 then rest on a horizontal transport path 38, which is arranged at a distance above the conveyor 29 and along which the bags 10 are transported in the conveying direction of the conveyor 29. The transport path 38 has a longitudinal section 39 through which the receiving pins 28 pass to receive the bags 10. The longitudinal section 39 runs parallel to the conveying direction on the conveyor 29.

Der Transport der Beutel 10 erfolgt zum einen durch die Aufnahmestifte 28, die über die Fördereinrichtung 29 in Förderrichtung bewegbar sind. Zudem ist ein weiteres Fördermittel 40 seitlich der Transportbahn 38 vorgesehen, bei dem es sich um einen Endlosförderer mit am Umfang des Fördergurtes angeordneten Mitnehmern 41 handeln kann. Das Fördermittel 40 wird synchron mit der Fördereinrichtung 29 angetrieben, wobei die Mitnehmer 41 so ausgerichtet sind, dass sie jeweils an einer Seitenkante der Beutel 10 anliegen, die quergerichtet zur Förderrichtung ist. Auf diese Weise wird das Bündel 13 aus Beuteln 10 nicht nur im Bereich der Aufhängelöcher 12 in Förderrichtung bewegt, sondern auch mit Abstand hierzu in der Nähe der Unterseite der Beutel 10. Auf diese Weise kann verhindert werden, dass sich die Beutel 10 während des Transports entlang der Transportbahn 38 schräg stellen.The transport of the bags 10 takes place on the one hand by the receiving pins 28, which are movable via the conveyor 29 in the conveying direction. In addition, a further conveyor 40 is provided laterally of the transport path 38, which may be an endless conveyor with arranged on the circumference of the conveyor belt drivers 41. The conveyor 40 is driven in synchronism with the conveyor 29, wherein the drivers 41 are aligned so that they each rest on a side edge of the bag 10, which is transverse to the conveying direction. In this way, the bundle 13 is moved out of bags 10 not only in the area of the suspension holes 12 in the conveying direction, but also at a distance in the vicinity of the bottom of the bag 10. In this way it can be prevented that the bag 10 during transport along the transport path 38 obliquely.

Eine weitere Maßnahme, um eine möglichst faltenfreie Zuführung der Beutel 10 zu gewährleisten, besteht in der Anordnung eines Organs zum Glätten der Beutel 10. Vorgesehen ist in diesem Fall eine Rampe 42 mit schräggerichteter bzw. ansteigender Vorderseite. Bei der Zuführung werden die Bündel 13 aus Beuteln 10 über die Rampe 42 gezogen und dabei geglättet (Fig. 7 bis 9).Another measure to ensure the most wrinkle-free feeding of the bag 10, consists in the arrangement of an organ for smoothing the bag 10. Provided in this case, a ramp 42 with angled or rising front. During feeding, the bundles 13 are pulled out of bags 10 via the ramp 42 and thereby smoothed ( Fig. 7 to 9 ).

Nach der Übergabe der Bündel 13 an die Aufnahmestifte 28 kann die Rampe 42 in vertikaler Richtung abgesenkt werden, damit sie den Abtransport der Beutel 10 nicht im Wege ist (Fig. 10). Vorzugsweise weist auch die Rampe 42 Vertiefungen 43 auf, zur Führung der Beutelträger 15. Ein Pneumatikzylinder 44 oder ein entsprechend geeignetes Organ kann zum Bewegen der Rampe 42 in vertikaler Richtung vorgesehen sein.After the transfer of the bundles 13 to the receiving pins 28, the ramp 42 can be lowered in the vertical direction, so that they do not impede the removal of the bags 10 ( Fig. 10 ). Preferably, the ramp 42 has recesses 43, for guiding the bag carrier 15. A pneumatic cylinder 44 or a correspondingly suitable member may be provided for moving the ramp 42 in the vertical direction.

Fig. 13 zeigt ein weiteres hilfreiches Detail der Vorrichtung. Demnach ist das freie Ende der Aufnahmestifte 28 angespitzt und formschlüssig in einer stirnseitigen Ausnehmung 45 im Bereich eines freien Endes 16 der Beutelträger 15 positionierbar. Auf diese Weise ist eine sichere Positionierung der freien Enden 16 der Beutelträger 15 auf den Aufnahmestiften 28 und damit eine problemlose Übergabe der Beutel gegeben. Fig. 13 shows another helpful detail of the device. Accordingly, the free end of the receiving pins 28 is sharpened and positively positioned in a frontal recess 45 in the region of a free end 16 of the bag carrier 15. In this way, a secure positioning of the free ends 16 of the bag carrier 15 on the receiving pins 28 and thus a problem-free transfer of the bag is given.

Nachdem die Beutel 10 an die Aufnahmestifte 28 der Fördereinrichtung 29 übergeben sind, werden die Beutelträger 15 angehoben, um einen Abtransport der Beutel 10 aus der Zuführstation 32 zu ermöglichen. Das Anheben wird im vorliegenden Fall dadurch bewirkt, dass an den Beutelträgern 15 seitlich abstehende Stifte 46 angebracht sind, die bei der Zuführung der Beutelträger 15 in die Übergabeposition in eine Kulissenführung 47 eingreifen. Durch Anheben der Kulissenführung 47 mittels eines Hebezylinders 48 (Fig. 10) wird das freie Ende 16 der Beutelträger 15 von den Aufnahmestiften 28 abgehoben und dabei die Beutelträger 15 um die Achse 17 geringfügig verschwenkt.After the bags 10 are transferred to the receiving pins 28 of the conveyor 29, the bag carrier 15 are raised to allow removal of the bag 10 from the feed station 32. The lifting is effected in the present case by the fact that 15 laterally projecting pins 46 are attached to the bag carriers, which engage in the feed position of the bag carrier 15 in the transfer position in a slotted guide 47. By raising the slide guide 47 by means of a lifting cylinder 48 ( Fig. 10 ), the free end 16 of the bag carrier 15 is lifted from the receiving pins 28 while the bag carrier 15 is pivoted about the axis 17 slightly.

Im Anschluss an das Anheben der Beutelträger 15 werden diese von den Mitnehmern 25 entlang eines aufrechten Fördertrums der Mitnehmerkette 26 gefördert und im Bereich einer oberen Umlenkrolle 27 an ein weiteres Paar von Laufschienen 19 übergeben. Die Laufschienen 19 sind in Richtung des Magazins 14 geneigt angeordnet, so dass die Laufwagen 20 per Schwerkraft zurück zum Magazin 14 bewegt werden. Alternativ ist es denkbar, dass die Beutelträger 15 bzw. die Laufwagen 20 nach der Übergabe der Beutel 10 abgefördert werden und an einen Zulieferer übergeben werden, der die Beutelträger 15 neu mit einem Bündel 13 aus Beuteln 10 bestückt.Following the lifting of the bag carrier 15, these are conveyed by the carriers 25 along an upright conveying run of the driving chain 26 and transferred to another pair of running rails 19 in the region of an upper deflecting roller 27. The rails 19 are arranged inclined in the direction of the magazine 14, so that the carriage 20 are moved by gravity back to the magazine 14. Alternatively, it is conceivable that the bag carriers 15 or the carriages 20 are conveyed away after the transfer of the bags 10 and are handed over to a supplier who newly equips the bag carriers 15 with a bundle 13 of bags 10.

Im Bereich des Magazins 14 und der Zuführstation 32 kann wie im vorliegenden Fall ein Schutzgestell 49 vorgesehen sein, um insbesondere einen unbeabsichtigten Eingriff in die Zuführung der Beutel 10 zu vermeiden. In Fig. 2 ist eine Art Fenster 50 im Schutzgestell 49 angedeutet. Dieses kann dazu dienen, die Laufwagen 20 mit Bündeln 13 dem Magazin 14 zuzuführen und ggf. leere Laufwagen 20 aus dem Prozess zur Wiederbefüllung in Empfang zu nehmen.In the area of the magazine 14 and the feed station 32, as in the present case, a protective frame 49 may be provided in order to avoid, in particular, an unintended intervention in the feeding of the bags 10. In Fig. 2 is a kind of window 50 indicated in the protective frame 49. This can serve to feed the carriages 20 with bundles 13 to the magazine 14 and possibly to receive empty carriages 20 from the process for refilling.

Im zweiten Ausführungsbeispiel gemäß Fig. 14 bis 17 kommt im Wesentlichen nur ein anderes Magazin 51 zum Einsatz als im ersten Ausführungsbeispiel. Es werden daher nur die Teile der Vorrichtung beschrieben, die anders ausgebildet sind als im ersten Ausführungsbeispiel.In the second embodiment according to FIGS. 14 to 17 In essence, only another magazine 51 is used as in the first embodiment. Therefore, only the parts of the device are described which are designed differently than in the first embodiment.

Das Magazin 51 ist im vorliegenden Fall karussellartig ausgebildet, mit in mehreren Ebenen angeordneten Beutelaufnahmen 52.The magazine 51 is designed in the present case carousel-like, with arranged in several levels bag receptacles 52nd

Jede Beutelaufnahme 52 verfügt im vorliegenden Fall über mehrere Beutelhalter 53. Die Beutelhalter 53 sind paarweise in mehreren Ebenen übereinander angeordnet und dienen zur Aufnahme jeweils eines Bündels 13 von Beuteln 10. Im vorliegenden Fall sind die Beutelhalter 53 jeweils paarweise in drei übereinander angeordneten Ebenen positioniert, so dass an jeder Beutelaufnahme 52 drei Bündel 13 von Beuteln 10 aufgenommen werden können. Es versteht sich, dass die Anzahl der Ebenen variieren kann. Denkbar sind insbesondere auch Beutelaufnahmen 52 mit einer größeren oder einer geringeren Anzahl an Beutelhaltern 53.Each bag holder 52 has several bag holders 53 in the present case. The bag holders 53 are arranged one above the other in pairs in several planes and serve to receive a respective bundle 13 of bags 10. In the present case, the bag holders 53 are each positioned in pairs in three superimposed planes, so that three bundles 13 of bags 10 can be received at each bag receptacle 52. It is understood that the number of levels may vary. Bag receptacles 52 with a larger or a smaller number of bag holders 53 are also conceivable.

In jeder Ebene des karussellartigen Magazins 51 sind die Beutelaufnahmen 52 an radial zu einer zentralen Achse 54 gerichteten Tragarmen 55 angeordnet. Im vorliegenden Fall sind in jeder Ebene des Magazins 51 sechs Tragarme 55 positioniert. Es versteht sich, dass die Anzahl der Tragarme 55 in jeder Ebene variieren kann. Denkbar sind insbesondere auch Ebenen mit einer größeren oder einer geringeren Anzahl an Tragarmen 55.In each plane of the carousel-like magazine 51, the bag receivers 52 are arranged on support arms 55 directed radially to a central axis 54. In the present case, six support arms 55 are positioned in each plane of the magazine 51. It is understood that the number of support arms 55 in each plane may vary. Also conceivable are planes with a larger or a smaller number of support arms 55.

Im gezeigten Ausführungsbeispiel verfügt das karussellartige Magazin 51 über zwei Ebenen mit Tragarmen 55. Denkbar sind aber auch hier eine größere oder geringere Anzahl an Ebenen, beispielsweise lediglich eine Ebene oder drei und mehr Ebenen.In the illustrated embodiment, the carousel-like magazine 51 has two levels with support arms 55. However, here are also conceivable a greater or lesser number of levels, for example, only one level or three or more levels.

Die Tragarme 55 einer Ebene sind mit einer gemeinsamen Tragplatte 56 verbunden, die um die aufrechte bzw. vertikale Achse 54 drehbar sind. Darüber hinaus sind einzelne Glieder der Achse 54 in vertikaler Richtung teleskopierbar, so dass die Tragplatten 56 bzw. die Tragarme 55 und letztendlich die Beutelaufnahmen 52 mit den daran befindlichen Bündeln 13 in vertikaler Richtung positioniert werden können.The support arms 55 of a plane are connected to a common support plate 56, which are rotatable about the upright or vertical axis 54. In addition, individual Telescopic members of the axis 54 in the vertical direction, so that the support plates 56 and the support arms 55 and ultimately the bag receivers 52 can be positioned with the bundles thereon 13 in the vertical direction.

Eine weitere Besonderheit ist in Fig. 16 und 17 gezeigt. Die Beutelhalter 53 der drei Ebenen sind an einer gemeinsamen Tragplatte 57 gelagert. Die Tragplatte 57 ist wiederum verbunden mit einem Pneumatikzylinder 58, der an einem Verfahrschlitten 59 angeordnet ist. Der Verfahrschlitten 59 selbst ist an einem schräg gerichteten Endabschnitt 60 der Tragarme 55 verfahrbar gelagert. Auf diese Weise können die Tragarme 55 in vertikaler und horizontaler Richtung positioniert werden, um die Bündel 13 zu übergeben.Another special feature is in FIGS. 16 and 17 shown. The bag holders 53 of the three levels are mounted on a common support plate 57. The support plate 57 is in turn connected to a pneumatic cylinder 58 which is arranged on a carriage 59. The carriage 59 itself is movably mounted on an obliquely directed end portion 60 of the support arms 55. In this way, the support arms 55 can be positioned in the vertical and horizontal directions to transfer the bundles 13.

Das Magazin 51 ist wie im ersten Ausführungsbeispiel von einem Schutzgestell 49 umgeben. An einer Seite ist eine Tür 61 vorgesehen, um Beutel 10 zum Magazin 51 hinzuzufügen.The magazine 51 is surrounded by a protective frame 49, as in the first exemplary embodiment. On one side, a door 61 is provided to add bag 10 to the magazine 51.

Das soweit in wesentlichen Teilen beschriebene Magazin 51 funktioniert wie folgt: Die Beutel 10 werden in Bündeln 13 durch einen Bediener im Bereich der Tür 61 den Beutelhaltern 53 zugeführt. Danach wird das Magazin 51 um eine Position weitergedreht, sodass die nächsten Beutelhalter 53 im Bereich der Tür 61 positioniert sind. Gegenüberliegend der Tür 61, in deren Bereich sich eine Zuführstation befindet, liegt eine Übergabestation 62, in deren Bereich die Beutel 10 an einen anschließenden Zuführförderer 63 übergeben werden.The magazine 51 thus far described functions as follows: The bags 10 are fed in bundles 13 to the bag holders 53 by an operator in the region of the door 61. Thereafter, the magazine 51 is further rotated by one position, so that the next bag holder 53 are positioned in the region of the door 61. Opposite the door 61, in the area of which there is a feed station, is a transfer station 62, in the area of which the bags 10 are transferred to a subsequent supply conveyor 63.

Der Zuführförderer 63 dient zur Zuführung der Bündel 13 an die Fördereinrichtung 29. Hierzu weist der Zuführförderer 63 Aufnahmestifte 64 für die Bündel 13 auf. Die Aufnahmestifte 64 des Zuführförderers 63 werden am Ende desselben analog zur Darstellung gemäß Fig. 13 über den Aufnahmestiften 28 der Fördereinrichtung 29 positioniert zur Übergabe der Bündel 13. Im vorliegenden Fall ist der Zuführförderer 63 als kontinuierlich angetriebener Endlosförderer ausgebildet, an dessen Förderertrumen nach außen abstehend die Aufnahmestifte 64 zum Eingriff in die Aufhängelöcher 12 der Beutel 10 angeordnet sind. Die Aufnahmestifte 64 sind paarweise nebeneinander angeordnet, wobei die Paare der Aufnahmestifte 64 in Förderrichtung des Zuführförderers 63 voneinander beabstandet sind. Die Bündel 13 werden im Bereich eines Untertrums 65 des Zuführförderers 63 mittels der Aufnahmestifte 64 in Förderrichtung gemäß Pfeil 66 transportiert. Dabei ruhen die flach liegenden Bündel 13 auf einer Transportbahn 67. In der Transportbahn 67 sind in Längsrichtung derselben verlaufende Ausnehmungen 68 angeordnet, durch die die Enden der Aufnahmestifte 64 hindurchtreten.The feed conveyor 63 is used to feed the bundles 13 to the conveyor 29. For this purpose, the feed conveyor 63 receiving pins 64 for the bundles 13. The receiving pins 64 of the feed conveyor 63 are at the end thereof analogous to the representation according to Fig. 13 In the present case, the feed conveyor 63 is formed as a continuously driven endless conveyor, on whose Förderertrumen outwardly projecting the receiving pins 64 are arranged to engage in the suspension holes 12 of the bag 10. The receiving pins 64 are arranged side by side in pairs, wherein the pairs of receiving pins 64 in the conveying direction of the feed conveyor 63 are spaced from each other. The bundles 13 are transported in the conveying direction according to arrow 66 in the region of a lower run 65 of the feed conveyor 63 by means of the receiving pins 64. The lying flat bundles 13 rest on a transport path 67. In the transport path 67 are arranged in the longitudinal direction of the same extending recesses 68 through which the ends of the receiving pins 64 pass.

Am Ende der Transportbahn 67 ist eine schwenkbare Klappe 69 vorgesehen, die nach Übergabe der Bündel 13 an die Aufnahmestifte 28 der Fördereinrichtung 29 verschwenkt werden kann, so dass die in Transportrichtung rückseitigen Enden der Bündel 13 herabfallen. Der weitere Transport der Bündel 13 erfolgt wie eingangs beschrieben.At the end of the transport path 67, a pivotable flap 69 is provided, which can be pivoted after transfer of the bundles 13 to the receiving pins 28 of the conveyor 29 so that the rear in the transport direction ends of the bundles 13 fall. The further transport of the bundles 13 takes place as described above.

Zur Übergabe der Bündel 13 von den Beutelaufnahmen 52 an den Zuführförderer 63 ist eine Übergabeeinrichtung 70 vorgesehen, die zwischen dem Magazin 51 und dem anschließenden Zuführförderer 63 positioniert ist. Die Übergabeeinrichtung 70 verfügt über ein Paar von Beutelhaltern 53, die einerseits schwenkbar und andererseits teleskopierbar gelagert sind. Zum Schwenken der Beutelhalter 53 ist ein Schwenkantrieb 71 vorgesehen, der mit einem Teleskopantrieb 72 zum Teleskopieren der Beutelhalter 53 kombiniert ist.For transferring the bundles 13 from the bag receivers 52 to the feed conveyor 63, a transfer device 70 is provided which is positioned between the magazine 51 and the subsequent feed conveyor 63. The transfer device 70 has a pair of bag holders 53 which are pivotally mounted on the one hand and telescopically on the other hand. For pivoting the bag holder 53, a pivot drive 71 is provided, which is combined with a telescopic drive 72 for telescoping the bag holder 53.

Die Übergabe der Bündel 13 vom Magazin 51 an den Zuführförderer 63 erfolgt derart, dass zunächst die Beutelhalter 53 des Magazins 51 fluchtend mit den Beutelhaltern 53 der Übergabeeinrichtung 70 positioniert werden (Fig. 16). Dabei erfolgt die Übergabe der Bündel 13 an die Übergabeeinrichtung 70. Anschließend wird die Übergabeeinrichtung 70 geschwenkt, so dass die Bündel 13 von den Aufnahmestiften 64 des Zuführförderers 63 übernommen werden können. Danach wird die Übergabeeinrichtung 70 zurückgeschwenkt zur Aufnahme des nächsten Bündels 13. Dieses Bündel 13 wird durch Einsatz des Pneumatikzylinders 58 und des Verfahrschlittens 59 rechtzeitig in eine zur Übergabe entsprechende Position gebracht.The transfer of the bundles 13 from the magazine 51 to the feed conveyor 63 takes place in such a way that first the bag holders 53 of the magazine 51 are positioned in alignment with the bag holders 53 of the transfer device 70 ( Fig. 16 ). In this case, the transfer of the bundles 13 to the transfer device 70. Subsequently, the transfer device 70 is pivoted so that the bundles 13 can be taken over by the receiving pins 64 of the feed conveyor 63. Thereafter, the transfer device 70 is pivoted back to receive the next bundle 13. This bundle 13 is brought by the use of the pneumatic cylinder 58 and the carriage 59 in a timely manner to the transfer position.

Nach dem alle Bündel 13 an einem Tragarm 55 übergeben wurden, können entweder die Bündel von einem Tragarm 55 einer anderen Ebene übergeben werden oder die Tragarme 55 werden um eine Position gedreht, sodass weiter aus der gleichen Ebene entnommen wird und erst nach Entnahme aller Bündel 13 einer Ebene aus einer anderen Ebene entnommen wird.After all bundles 13 have been transferred to a support arm 55, either the bundles can be transferred from a support arm 55 of another level or the support arms 55 are rotated by one position, so that further removed from the same level and only after removal of all bundles 13th one level from another level.

Wie Figur 17 zeigt, kann die Übergabeeinrichtung 70 die Bündel 13 oberhalb der Transportbahn 67 zuführen. Im vorliegenden Fall ist ein freies Ende der Transportbahn 67 zur Erleichterung dieser Maßnahme abgerundet in Richtung der Übergabeeinrichtung 70.As FIG. 17 shows, the transfer device 70, the bundles 13 above the transport path 67 perform. In the present case, a free end of the transport path 67 is rounded off in the direction of the transfer device 70 in order to facilitate this measure.
