Definitions

  • the invention relates to a method for packaging compressible objects, in particular stacks of paper handkerchiefs, into a blank made of plastic film or the like, the object being first compressed and then taking the blank which lies around the object in a U-shape is inserted into a pocket of a revolving folding revolver.
  • the invention further relates to a device for packaging such objects.
  • a cyclically driven rotating unit has pockets arranged on the periphery for receiving stacks. The latter are first compressed in the area of an insertion station and then, when the unit is at a standstill, inserted into the pockets of the unit. The cyclical operation of the unit limits the performance of the device.
  • the invention is based on the object of proposing a method and a device for packaging stacks of paper handkerchiefs in particular, by means of which or by means of which precisely shaped cuboid packs can be produced with a considerably increased performance of the packaging machine.
  • the device according to the invention is characterized in that the folding turret is continuously rotating and an insertion platform and a pressing element corresponding thereto can be moved back and forth in the circumferential direction of the folding turret.
  • the incoming batches of paper handkerchiefs are pressed together and inserted in this shape into the pocket of a revolving folding revolver, while at the same time taking along a U-shaped blank made of plastic film or the like.
  • the pockets of the folding turret are expediently dimensioned somewhat larger (width in the circumferential direction of the folding turret) than the compressed stack. This makes it easier to insert the stack while taking the blank with it.
  • the stack remains under tension in the pocket, i.e. compressed.
  • the folding tabs of the blank that protrude on the radially outer side and on the axial sides are folded and thermally sealed.
  • the almost finished packs pushed out of the pockets of the folding revolver have a very exact cuboid shape.
  • the folding turret is assigned a stacking arm that can be moved up and down in the direction of rotation, onto which the objects to be packaged - stack of paper handkerchiefs - are pushed during a momentary standstill in the movement end position, accelerated to the peripheral speed of the folding turret and then into an adjacent pocket be inserted.
  • a press rocker works together with the stacking rocker and, after a stack has been pushed onto an insertion platform, compresses the stack, that is to say the object to be packed, from above.
  • This process takes place during the acceleration of the stack to the circumferential speed of the folding turret, so that when the folding turret or pocket is currently synchronized with the insertion platform of the stacking rocker, insertion into the pocket can take place in the radial direction.
  • a pusher station of the folding turret is assigned an ejecting platform that can also be swung back and forth or up and down, which picks up the pack pushed out of the pocket of the folding turret when it is temporarily synchronized with the folding turret and transfers it to a conveyor during a standstill phase.
  • a considerable increase in performance of the device according to the invention is brought about by two-track operation. Accordingly, two packs are produced simultaneously on two adjacent webs.
  • a single, common folding turret with appropriate dimensions in the axial direction is used with continuous pockets for receiving two adjacent packs as well as with correspondingly sized common organs, such as a package swing arm, compression swing arm, push-in unit, ejector and extension platform.
  • Further features of the invention relate to the configuration of the folding turret and the organs for feeding and removing the items to be packaged Items and packages.
  • the device shown as an exemplary embodiment in the drawings is used for packaging stacks 10 of paper handkerchiefs. These are folded one on top of the other, a stack 10 usually consisting of ten paper handkerchiefs. The stack 10 is encased in a blank 11 made of a thin plastic film.
  • the central unit of the device is a folding turret 12, which is driven to rotate at a continuous speed, in the illustration according to FIG. 1 in a clockwise direction.
  • the folding turret 12 has a plurality of pockets 13 arranged distributed along the circumference, in which the objects to be packaged - individually or in pairs - are received with a blank 11.
  • the pockets 13 are open on the radially outer side and at the axial ends.
  • the stacks 10 are fed to the folding turret 12 in the region of an insertion station 14.
  • a feed conveyor 15, which extends in a horizontal plane, namely in the central plane with respect to the folding turret 12, leads to this.
  • This is designed as a chain conveyor.
  • Carriers 16 are attached to two chains 17, 18 running side by side.
  • the stack 10 to be transported lies on a conveyor plate 19 in a sliding manner.
  • the chains 17, 18 are arranged offset in the region of their deflection in such a way that the drivers 16 connected to each chain 17, 18 are moved parallel downwards, that is to say without pivoting. As a result, the supplied stacks 10 can be placed exactly at one end position without shifting the individual layers.
  • the stacks 10 are conveyed by the feed conveyor 15 except for a slide-in platform 20 which is provided adjacent to the circumference of the folding turret 12. This is arranged on the end of a rocker which is moved back and forth about the center of rotation of the folding turret 12, namely in the vertical plane, namely a stacking rocker 21.
  • the stacking rocker 21 is pivotally mounted coaxially to the folding turret 12, the end projecting beyond the folding turret 12 forms the insertion platform 20.
  • the stacking arm 21 can be moved with the insertion platform from a lower starting position (solid lines in FIG. 1) to an upper reversing position (dash-dotted lines in FIG. 1). In the lower starting position, the insertion platform 20 extends essentially as an extension of the feed conveyor 15. During a current standstill phase, the stack 10 is placed on the insertion platform 20 by the synchronously controlled feed conveyor 15.
  • a pressing member comes into effect, namely a pressing plate 22 which is lowered onto the stack 10 from above and compresses it considerably.
  • the stack 10 is moved by the stacking rocker 21 in the direction of rotation of the folding turret, with the pressing plate 22 being carried along.
  • the stack 10 is compressed in the radial direction by an insert 23 into the one rotating in the same plane Pocket 13 of the folding turret 12 inserted.
  • the dimension of the pocket 13 in the circumferential direction corresponds to the size of the pack 24 to be produced.
  • the stack 10 is expediently compressed somewhat more than the circumferential dimension of the pocket 13, so that insertion is facilitated.
  • the press plate 22 is attached to the underside of a press rocker 25 which can be moved synchronously with the stacking rocker 21. Like the stacking rocker 21, this can be pivoted about the center of rotation of the folding turret 12.
  • the press rocker 25 is moved with the stack rocker 21 while maintaining the press position in the direction of rotation of the folding turret 12. After inserting the compressed stack 10 into the pocket, the press rocker 25 with the stack rocker 21 returns to the starting position, but initially at a greater distance therefrom, so that the stack 10 not compressed can be conveyed freely onto the insertion platform 20.
  • the pusher 23 is relatively movably connected to the press rocker 25. This is provided outside the area of the folding turret 12 with an elongated hole 26, in which a guide roller 27 connected to the insert 23 can be moved to and fro.

  • the handlebar 28 is in turn connected to a crank arm 29 which is pivotable about the axis of rotation of the folding turret 12.
  • a movement of the link 28 causes a linear displacement of the pusher 23 while pushing the stack 10 into a pocket 13.
  • the pusher 23 is hook-shaped so that the stack 10 can be gripped on the outside.
  • the stacks 10 are each pushed into the pockets 13 with the blank 11 held ready in the insertion station 14.
  • the blanks 11 are brought to the circumference of the folding turret 12 via a deflection roller 30.
  • This is provided with a plurality of suction bores 31, 32 opening on the peripheral surface.
  • the arrangement of the same is such that two suction bores 32 or groups of suction bores 32 are arranged on either side of a pocket 13.
  • each blank is fixed at its front and rear edges in the conveying direction and on both sides of the pocket 13 by suction air.
  • the suction bores 31, 32 are connected to a vacuum source via a suction segment 33 and a radial suction line 34.

Description

Die Erfindung betrifft ein Verfahren zum Verpacken von zusammendrückbaren Gegenständen, insbesondere von Stapeln aus Papier-Taschentüchern, in einen Zuschnitt aus Kunststoff-Folie od. dgl., wobei der Gegenstand zunächst zusammengedrückt und dann unter Mitnahme des sich U-förmig um den Gegenstand herumlegenden Zuschnitts in eine Tasche eines umlaufenden Faltrevolvers eingeschoben wird. Weiterhin betrifft die Erfindung eine Vorrichtung zum Verpacken derartiger Gegenstände.The invention relates to a method for packaging compressible objects, in particular stacks of paper handkerchiefs, into a blank made of plastic film or the like, the object being first compressed and then taking the blank which lies around the object in a U-shape is inserted into a pocket of a revolving folding revolver. The invention further relates to a device for packaging such objects.

Bei der Verpackung von Zellstofferzeugnissen, insbesondere Stapeln aus Papier-Taschentüchern, besteht ein erhebliches Problem darin, daß die zu verpackenden Gegenstände beträchtlich zusammendrückbar sind. Dadurch ist es schwierig, eine exakte quaderförmige Packung zu gestalten. Aus der FR-A-1 448 273 ist ein Verfahren und eine Vorrichtung bekannt, bei der ein taktweise angetriebenes rotierendes Aggregat am Umfang angeordnete Taschen zur Aufnahme von Stapeln aufweist. Letztere werden im Bereich einer Einschubstation zunächst zusammengedrückt und dann, bei Stillstand des Aggregats, in die Taschen desselben eingeschoben. Der taktweise Betrieb des Aggregats begrenzt die Vorrichtung in ihrer Leistungsfähigkeit.When packaging cellulose products, in particular stacks of paper handkerchiefs, there is a considerable problem in that the objects to be packaged are considerably compressible. This makes it difficult to design an exact cuboid packing. From FR-A-1 448 273 a method and a device are known in which a cyclically driven rotating unit has pockets arranged on the periphery for receiving stacks. The latter are first compressed in the area of an insertion station and then, when the unit is at a standstill, inserted into the pockets of the unit. The cyclical operation of the unit limits the performance of the device.

Der Erfindung liegt nun die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung für die Verpakkung von insbesondere Stapeln aus Papier-Taschentüchern vorzuschlagen, durch das bzw. durch die exakt geformte quaderförmige Packungen herstellbar sind bei beträchtlich erhöhter Leistung der Verpackungsmaschine.The invention is based on the object of proposing a method and a device for packaging stacks of paper handkerchiefs in particular, by means of which or by means of which precisely shaped cuboid packs can be produced with a considerably increased performance of the packaging machine.

Zur Lösung dieser Aufgabe ist das erfindungsgemäße Verfahren durch folgende Merkmale gekennzeichnet:

  • a) der Faltrevolver läuft kontinuierlich um,
  • b) der Gegenstand wird zum Einschieben auf die Umfangsgeschwindigkeit des Faltrevolvers beschleunigt und
  • c) das Zusammendrücken des Gegenstands erfolgt während der Beschleunigung auf die Umfangsgeschwindigkeit.
To achieve this object, the method according to the invention is characterized by the following features:
  • a) the folding turret rotates continuously,
  • b) the object is accelerated for insertion to the peripheral speed of the folding turret and
  • c) the object is compressed during acceleration to the peripheral speed.

In entsprechender Weise ist die erfindungsgemäße Vorrichtung dadurch gekennzeichnet, daß der Faltrevolver kontinuierlich umlaufend ist und eine Einschubplattform und ein hierzu korrespondierendes Preßorgan in Umfangsrichtung des Faltrevolvers hin- und herbewegbar sind.In a corresponding manner, the device according to the invention is characterized in that the folding turret is continuously rotating and an insertion platform and a pressing element corresponding thereto can be moved back and forth in the circumferential direction of the folding turret.

Bei der Ausführung des Verfahrens wird so vorgegangen, daß die ankommenden Stapel aus Papier-Taschentüchern zusammengedrückt und in dieser Gestalt in die Tasche eines umlaufenden Faltrevolvers eingeschoben werden unter gleichzeitiger Mitnahme eines sich U-förmig um den Stapel herumlegenden Zuschnitts aus Kunststoff-Folie oder dergleichen. Die Taschen des Faltrevolvers sind zweckmäßigerweise etwas größer bemessen (Breite in Umfangsrichtung des Faltrevolvers) als der zusammengedrückte Stapel. Dadurch ist der Einschub des Stapels unter Mitnahme des Zuschnitts erleichtert. In der Tasche bleibt der Stapel weiterhin unter Spannung, also zusammengedrückt. Während des Transports der Stapel durch den kontinuierlich umlaufenden Faltrevolver werden die an der radial äußeren Seite sowie sowie an den axialen Seiten überstehenden Faltlappen des Zuschnitts gefaltet und thermisch gesiegelt. Die aus den Taschen des Faltrevolvers ausgeschobenen, nahezu fertiggestellten Packungen haben eine sehr exakte quaderförmige Form.In carrying out the method, the incoming batches of paper handkerchiefs are pressed together and inserted in this shape into the pocket of a revolving folding revolver, while at the same time taking along a U-shaped blank made of plastic film or the like. The pockets of the folding turret are expediently dimensioned somewhat larger (width in the circumferential direction of the folding turret) than the compressed stack. This makes it easier to insert the stack while taking the blank with it. The stack remains under tension in the pocket, i.e. compressed. During the transport of the stacks through the continuously revolving folding turret, the folding tabs of the blank that protrude on the radially outer side and on the axial sides are folded and thermally sealed. The almost finished packs pushed out of the pockets of the folding revolver have a very exact cuboid shape.

Dem Faltrevolver ist erfindungsgemäß eine in Umlaufrichtung desselben auf und abbewegbare Stapelschwinge zugeordnet, auf die die zu verpakkenden Gegenstände - Stapel von Papier-Taschentüchern - während eines momentanen Stillstands in der Bewegungs-Endstellung aufgeschoben, auf die Umfangsgeschwindigkeit des Faltrevolvers beschleunigt und dann in eine benachbarte Tasche desselben eingeschoben werden. Mit der Stapelschwinge arbeitet eine Preßschwinge zusammen, die nach dem Aufschieben eines Stapels auf eine Einschubplattform von oben her den Stapel, also den zu verpackenden Gegenstand, zusammendrückt. Dieser Vorgang findet während der Beschleunigung des Stapels auf die Umfangsgeschwindigkeit des Faltrevolvers statt, so daß bei momentanem Gleichlauf von Faltrevolver bzw. Tasche desselben mit der Einschubplattform der Stapelschwinge der Einschub in die Tasche in radialer Richtung erfolgen kann.According to the invention, the folding turret is assigned a stacking arm that can be moved up and down in the direction of rotation, onto which the objects to be packaged - stack of paper handkerchiefs - are pushed during a momentary standstill in the movement end position, accelerated to the peripheral speed of the folding turret and then into an adjacent pocket be inserted. A press rocker works together with the stacking rocker and, after a stack has been pushed onto an insertion platform, compresses the stack, that is to say the object to be packed, from above. This process takes place during the acceleration of the stack to the circumferential speed of the folding turret, so that when the folding turret or pocket is currently synchronized with the insertion platform of the stacking rocker, insertion into the pocket can take place in the radial direction.

Einer Ausschubstation des Faltrevolvers ist eine ebenfalls schwingend hin und her- bzw. auf-und abbewegbare Ausschubplattform zugeordnet, die die aus der Tasche des Faltrevolvers ausgeschobene Packung bei zeitweiligem Gleichlauf mit dem Faltrevolver aufnimmt und während einer Stillstandsphase an einen Abförderer übergibt.A pusher station of the folding turret is assigned an ejecting platform that can also be swung back and forth or up and down, which picks up the pack pushed out of the pocket of the folding turret when it is temporarily synchronized with the folding turret and transfers it to a conveyor during a standstill phase.

Eine beträchtliche Leistungssteigerung der erfindungsgemäßen Vorrichtung wird durch zweibahnige Betriebsweise bewirkt. Es werden demnach auf zwei nebeneinanderliegenden Bahnen gleichzeitig zwei Packungen hergestellt. Hierzu wird ein einziger, gemeinsamer Faltrevolver bei entsprechender Abmessung in Axialrichtung verwendet mit durchgehenden Taschen zur Aufnahme von jeweils zwei nebeneinanderliegenden Packungen sowie mit ebenfalls entsprechend bemessenen gemeinsamen Organen, wie Paketschwinge, Preßschwinge, Einschieber, Ausstoßer und Ausschubplattform.A considerable increase in performance of the device according to the invention is brought about by two-track operation. Accordingly, two packs are produced simultaneously on two adjacent webs. For this purpose, a single, common folding turret with appropriate dimensions in the axial direction is used with continuous pockets for receiving two adjacent packs as well as with correspondingly sized common organs, such as a package swing arm, compression swing arm, push-in unit, ejector and extension platform.

Weitere Merkmale der Erfindung betreffen die Ausgestaltung des Faltrevolvers sowie der Organe zum Zuführen und Abfördern der zu verpackenden Gegenstände und Pakkungen.Further features of the invention relate to the configuration of the folding turret and the organs for feeding and removing the items to be packaged Items and packages.

Die in den Zeichnungen als Ausführungsbeispiel dargestellte Vorrichtung dient zur Verpackung von Stapeln 10 von Papier-Taschentüchern. Diese sind gefaltet übereinandergelegt, wobei ein Stapel 10 üblicherweise aus zehn Papier-Taschentüchern besteht. Der Stapel 10 wird in einen Zuschnitt 11 aus einer dünnen Kunststoff-Folie eingehüllt.The device shown as an exemplary embodiment in the drawings is used for packaging stacks 10 of paper handkerchiefs. These are folded one on top of the other, a stack 10 usually consisting of ten paper handkerchiefs. The stack 10 is encased in a blank 11 made of a thin plastic film.

Zentrales Aggregat der Vorrichtung ist ein Faltrevolver 12, der mit kontinuierlicher Geschwindigkeit rotierend angetrieben ist, bei der Darstellung gemäß Fig. 1 im Uhrzeigersinn.The central unit of the device is a folding turret 12, which is driven to rotate at a continuous speed, in the illustration according to FIG. 1 in a clockwise direction.

Der Faltrevolver 12 weist eine Mehrzahl von längs des Umfangs verteilt angeordneten Taschen 13 auf, in denen die zu verpackenden Gegenstände - einzeln oder paarweise - mit Zuschnitt 11 Aufnahme finden. Die Taschen 13 sind auf der radial äußeren Seite sowie an den axialen Enden offen.The folding turret 12 has a plurality of pockets 13 arranged distributed along the circumference, in which the objects to be packaged - individually or in pairs - are received with a blank 11. The pockets 13 are open on the radially outer side and at the axial ends.

Die Stapel 10 werden dem Faltrevolver 12 im Bereich einer Einschubstation 14 zugeführt. Zu dieser führt ein sich in horizontaler Ebene, und zwar in der Mittelebene in bezug auf den Faltrevolver 12, erstreckender Zuförderer 15. Dieser ist hier als Kettenförderer ausgebildet. Mitnehmer 16 sind an zwei nebeneinander laufenden Ketten 17, 18 angebracht. Der zu transportierende Stapel 10 liegt gleitend auf einer Förderplatte 19 auf. Die Ketten 17, 18 sind im Bereich ihrer Umlenkung so versetzt angeordnet, daß die mit jeder Kette 17, 18 verbundenen Mitnehmer 16 parallel nach unten bewegt werden, also ohne Verschwenkung. Dadurch können die zugeführten Stapel 10 ohne Verschiebung der einzelnen Lagen exakt an einer Endposition abgesetzt werden.The stacks 10 are fed to the folding turret 12 in the region of an insertion station 14. A feed conveyor 15, which extends in a horizontal plane, namely in the central plane with respect to the folding turret 12, leads to this. This is designed as a chain conveyor. Carriers 16 are attached to two chains 17, 18 running side by side. The stack 10 to be transported lies on a conveyor plate 19 in a sliding manner. The chains 17, 18 are arranged offset in the region of their deflection in such a way that the drivers 16 connected to each chain 17, 18 are moved parallel downwards, that is to say without pivoting. As a result, the supplied stacks 10 can be placed exactly at one end position without shifting the individual layers.

Die Stapel 10 werden durch den Zuförderer 15 bis auf eine benachbart zum Umfang des Faltrevolvers 12 bereitgehaltene Einschubplattform 20 gefördert. Diese ist auf dem Ende einer um den Drehmittelpunkt des Faltrevolvers 12 hin- und her-, nämlich in vertikaler Ebene, bewegten Schwinge, nämlich einer Stapelschwinge 21, angeordnet. Die Stapelschwinge 21 ist coaxial zum Faltrevolver 12 schwenkbar gelagert, das über den Faltrevolver 12 hinausragende Ende bildet die Einschubplattform 20.The stacks 10 are conveyed by the feed conveyor 15 except for a slide-in platform 20 which is provided adjacent to the circumference of the folding turret 12. This is arranged on the end of a rocker which is moved back and forth about the center of rotation of the folding turret 12, namely in the vertical plane, namely a stacking rocker 21. The stacking rocker 21 is pivotally mounted coaxially to the folding turret 12, the end projecting beyond the folding turret 12 forms the insertion platform 20.

Die Stapelschwinge 21 ist mit der Einschubplattform aus einer unteren Ausgangsstellung (ausgezogenen Linien in Fig. 1) in eine obere Umkehrstellung (strichpunktiert in Fig. 1) bewegbar. In der unteren Ausgangsstellung erstreckt sich die Einschubplattform 20 im wesentlichen in Verlängerung des Zuförderers 15. Während einer momentanen Stillstandsphase wird der Stapel 10 durch den synchron gesteuerten Zuförderer 15 auf der Einschubplattform 20 abgelegt.The stacking arm 21 can be moved with the insertion platform from a lower starting position (solid lines in FIG. 1) to an upper reversing position (dash-dotted lines in FIG. 1). In the lower starting position, the insertion platform 20 extends essentially as an extension of the feed conveyor 15. During a current standstill phase, the stack 10 is placed on the insertion platform 20 by the synchronously controlled feed conveyor 15.

Unmittelbar nach Absetzen eines Stapel 10 auf der Einschubplattform 20 kommt ein Preßorgan zur Wirkung, nämlich eine Preßplatte 22, die von oben her auf den Stapel 10 abgesenkt wird und diesen beträchtlich zusammendrückt. In diesem komprimierten Zustand wird der Stapel 10 durch die Stapelschwinge 21 in Drehrichtung des Faltrevolvers bewegt unter Mitführung der Preßplatte 22. Bei Erreichen der Umfangsgeschwindigkeit des Faltrevolvers 12 wird der Stapel 10 in der zusammengedrückten Form in Radialrichtung durch einen Einschieber 23 in die in gleicher Ebene umlaufende Tasche 13 des Faltrevolvers 12 eingeschoben. Die Abmessung der Tasche 13 in Umfangsrichtung entspricht der Größe der herzustellenden Packung 24. Zweckmäßigerweise wird der Stapel 10 etwas stärker zusammengedrückt als die Umfangsabmessung der Tasche 13, so daß das Einschieben erleichtert wird.Immediately after depositing a stack 10 on the insertion platform 20, a pressing member comes into effect, namely a pressing plate 22 which is lowered onto the stack 10 from above and compresses it considerably. In this compressed state, the stack 10 is moved by the stacking rocker 21 in the direction of rotation of the folding turret, with the pressing plate 22 being carried along. When the peripheral speed of the folding turret 12 is reached, the stack 10 is compressed in the radial direction by an insert 23 into the one rotating in the same plane Pocket 13 of the folding turret 12 inserted. The dimension of the pocket 13 in the circumferential direction corresponds to the size of the pack 24 to be produced. The stack 10 is expediently compressed somewhat more than the circumferential dimension of the pocket 13, so that insertion is facilitated.

Die Preßplatte 22 ist an der Unterseite einer synchron mit der Stapelschwinge 21 bewegbaren Preßschwinge 25 angebracht. Diese ist, wie die Stapelschwinge 21, um den Drehmittelpunkt des Faltrevolvers 12 schwenkbar. Die Preßschwinge 25 wird mit der Stapelschwinge 21 unter Aufrechterhaltung der Preßstellung in Drehrichtung des Faltrevolvers 12 bewegt. Nach dem Einschub des zusammengedrückten Stapels 10 in die Tasche kehrt die Preßschwinge 25 mit der Stapelschwinge 21 in die Ausgangsstellung zurück, jedoch zunächst mit einem größeren Abstand von dieser, so daß der nicht zusammengedrückte Stapel 10 frei auf die Einschubplattform 20 gefördert werden kann.The press plate 22 is attached to the underside of a press rocker 25 which can be moved synchronously with the stacking rocker 21. Like the stacking rocker 21, this can be pivoted about the center of rotation of the folding turret 12. The press rocker 25 is moved with the stack rocker 21 while maintaining the press position in the direction of rotation of the folding turret 12. After inserting the compressed stack 10 into the pocket, the press rocker 25 with the stack rocker 21 returns to the starting position, but initially at a greater distance therefrom, so that the stack 10 not compressed can be conveyed freely onto the insertion platform 20.

Der Einschieber 23 ist relativ beweglich mit der Preßschwinge 25 verbunden. Diese ist außerhalb des Bereichs des Faltrevolvers 12 mit einem Langloch 26 versehen, in dem eine mit dem Einschieber 23 verbundene Führungsrolle 27 hin- und herbewegbar ist. Die Führungsrolle 27 sitzt an einem Lenker 28, mit dem der Einschieber 23 hin- und herbewegt wird. Der Lenker 28 wiederum ist mit einem Kurbelarm 29 verbunden, der um die Drehachse des Faltrevolvers 12 schwenkbar ist. Eine Bewegung des Lenkers 28 bewirkt eine lineare Verschiebung des Einschiebers 23 unter Einschieben des Stapels 10 in eine Tasche 13. Der Einschieber 23 ist hakenförmig ausgebildet, so daß der Stapel 10 an der Außenseite erfaßt werden kann.The pusher 23 is relatively movably connected to the press rocker 25. This is provided outside the area of the folding turret 12 with an elongated hole 26, in which a guide roller 27 connected to the insert 23 can be moved to and fro. The guide roller 27 sits on one Handlebar 28 with which the slider 23 is moved back and forth. The handlebar 28 is in turn connected to a crank arm 29 which is pivotable about the axis of rotation of the folding turret 12. A movement of the link 28 causes a linear displacement of the pusher 23 while pushing the stack 10 into a pocket 13. The pusher 23 is hook-shaped so that the stack 10 can be gripped on the outside.

Die Stapel 10 werden jeweils unter Mitnahme des in der Einschubstation 14 bereitgehaltenen Zuschnitts 11 in die Taschen 13 eingeschoben. Die Zuschnitte 11 werden zu diesem Zweck über eine Umlenkwalze 30 an den Umfang des Faltrevolvers 12 herangeführt. Dieser ist mit einer Mehrzahl von an der Umfangsfläche mündenden Saugbohrungen 31, 32 versehen. Die Anordnung derselben ist so getroffen, daß jeweils zwei Saugbohrungen 32 bzw. Gruppen von Saugbohrungen 32 zu beiden Seiten einer Tasche 13 angeordnet sind. Dadurch wird jeder Zuschnitt an seinen in Förderrichtung vorderen und rückwärtigen Rändern sowie zu beiden Seiten der Tasche 13 durch Saugluft fixiert. Die Saugbohrungen 31, 32 sind über ein Saugsegment 33 und eine radiale Saugleitung 34 mit einer Unterdruckquelle verbunden.The stacks 10 are each pushed into the pockets 13 with the blank 11 held ready in the insertion station 14. For this purpose, the blanks 11 are brought to the circumference of the folding turret 12 via a deflection roller 30. This is provided with a plurality of suction bores 31, 32 opening on the peripheral surface. The arrangement of the same is such that two suction bores 32 or groups of suction bores 32 are arranged on either side of a pocket 13. As a result, each blank is fixed at its front and rear edges in the conveying direction and on both sides of the pocket 13 by suction air. The suction bores 31, 32 are connected to a vacuum source via a suction segment 33 and a radial suction line 34.

Das Saugsegment 33 erstreckt sich in Umfangsrichtung bis in einen Bereich im Anschluß an die Einschubstation 14. Danach folgt ein Blasluftsegment 35, welches über eine Druckluftleitung 36 während einer Teilstrecke Luft durch die Saugbohrungen 31, 32 hindurchleitet. Dadurch wird insbesondere durch die unmittelbar zu beiden Seiten der Tasche 13 angeordneten Saugbohrungen 32 ein die Radialstellung von Schlauchlappen 37 und 38 stabilisierender Luftstrom erzeugt. Diese nach dem Einschieben des Stapels 10 mit dem U-förmig gefalteten Zuschnitt 11 in die Tasche 13 außen überstehenden bzw. aus der Tasche herausragenden Schlauchlappen 37, 38 werden nun gefaltet, und zwar zuerst der in Förderrichtung rückwärtige Schlauchlappen 37 durch einen schwenkbaren Falter 39, der den Schlauchlappen 37 von rückwärts gegen die äußere Seitenfläche des Stapels 10 faltet.The suction segment 33 extends in the circumferential direction into an area following the insertion station 14. This is followed by a blowing air segment 35, which conducts air through the suction bores 31, 32 over a partial distance via a compressed air line 36. As a result, an air flow which stabilizes the radial position of tubular flaps 37 and 38 is generated in particular by the suction bores 32 arranged directly on both sides of the pocket 13. These tubular flaps 37, 38 which protrude from the outside or protrude from the pocket after inserting the stack 10 with the U-shaped blank 11 into the pocket 13 are now folded, namely first the tubular flap 37 rearward in the conveying direction by a pivotable folder 39, which folds the tubular tab 37 from the rear against the outer side surface of the stack 10.

Nachfolgend gelangt die Tasche 13 mit Stapel 10 und teilweise gefaltetem Zuschnitt 11 in den Bereich eines Siegelaggregats 40. Dieses besteht aus einem endlosen umlaufenden, nämlich mit der Geschwindigkeit des Faltrevolvers 12 bewegten, Abdeckband 41 aus wärmebeständigem Material, insbesondere aus einem textilen Teflonband. Das Abdeckband 41 wird über zwei in größerem Abstand voneinander angeordnete, unmittelbar benachbart zum Umfang des Faltrevolvers 12 angeordnete Umlenkrollen 42, 43 geführt. Eine dritte Umlenkrolle 44 ist dem rückseitigen, äußeren Trum des Abdeckbandes 41 zugeordnet. Durch die Relativstellung der Umlenkrollen 42, 43 schmiegt sich ein fördernder bzw. mitlaufender Fördertrum an die Umfangsfläche des Faltrevolvers 12 an. An der Außenseite des Fördertrums 45 befindet sich ein Heizelement, nämlich ein bogenförmiges Heizsegment 46. Dieses ist konzentrisch zum Faltrevolver 12 bogenförmig ausgebildet, jedoch so angeordnet, daß es keine ständige Berührung mit dem Abdeckband 41 bzw. dessen Fördertrum 45 hat.Subsequently, the pocket 13 with stack 10 and partially folded blank 11 arrives in the area of a sealing unit 40. This consists of an endless revolving cover band 41 made of heat-resistant material, in particular a textile Teflon band, which moves at the speed of the folding turret 12. The cover band 41 is guided over two deflection rollers 42, 43 which are arranged at a greater distance from one another and are arranged directly adjacent to the circumference of the folding turret 12. A third deflection roller 44 is assigned to the rear, outer run of the cover band 41. Due to the relative position of the deflecting rollers 42, 43, a conveying or moving conveying strand nestles against the peripheral surface of the folding turret 12. On the outside of the conveyor run 45 there is a heating element, namely an arc-shaped heating segment 46. This is arc-shaped concentrically to the folding turret 12, but is arranged so that it has no constant contact with the cover band 41 or its conveyor run 45.

Wenn die Tasche 13 mit dem Inhalt in den Bereich des Abdeckbandes 41 gelangt, wird der in Förderrichtung vorn liegende Schlauchlappen 38 gegen die außenliegende Seitenfläche umgefaltet unter teilweiser Überdeckung mit dem Schlauchlappen 37. Bei der weiteren Förderung gelangt der Stapel 10 mit Zuschnitt 11 in den Bereich des Heizsegments 46. Dabei ist von Bedeutung, daß aufgrund der entsprechend gewählten Abmessungen der Stapel 10 einschließlich gefaltetem Zuschnitt 11 geringfügig in Radialrichtung aus der Tasche 13 herausragt, also über die Umfangsfläche des Faltrevolvers 12 hinwegsteht. Dadurch wird das Abdeckband 41 bzw. dessen Fördertrum 45 im Bereich einer Tasche 13 durch den Stapel 10 geringfügig angehoben, nämlich bis zur Anlage an dem Heizsegment 46. Hier wird somit örtlich im Bereich der gefalteten Schlauchlappen 37, 38 die Wärme zur Durchführung der Siegelung und auch ein gewisser Druck übertragen. Das Heizsegment 46 erstreckt sich über einen dem Abstand von drei aufeinanderfolgenden Taschen 13 entsprechenden Bereich des Faltrevolvers 12, ausreichend, um eine stabile Siegelung durchzuführen.When the bag 13 with the contents reaches the area of the cover band 41, the tubular flap 38 lying forward in the conveying direction is folded over against the outer side surface with partial overlap with the tubular flap 37. During further conveyance, the stack 10 with blank 11 arrives in the area of the heating segment 46. It is important that, due to the dimensions chosen accordingly, the stack 10 including the folded blank 11 protrudes slightly in the radial direction from the pocket 13, that is to say it projects beyond the circumferential surface of the folding turret 12. As a result, the cover band 41 or its conveying strand 45 is raised slightly in the area of a pocket 13 by the stack 10, namely until it comes into contact with the heating segment 46. The heat for carrying out the sealing and also transferred some pressure. The heating segment 46 extends over a region of the folding turret 12 corresponding to the distance between three successive pockets 13, sufficient to carry out a stable sealing.

Das Heizsegment 46 ist durch im einzelnen nicht gezeigte Organe radial verstellbar, nämlich aus der Heizposition zurückbewegbar, wenn während einer Betriebsunterbrechung keine Packungen zugeführt werden oder wenn der Faltrevolver 12 zeitweilig stillsteht.The heating segment 46 is radially adjustable by means not shown in detail, namely, can be moved back out of the heating position if no packs are supplied during an interruption in operation or if the folding turret 12 is temporarily stationary.

Die in bezug auf die außenliegende Schlauchfaltung (Schlauchlappen 37, 38) fertiggestellte Pakkung gelangt mit der zugeordneten Tasche nun in den Bereich einer Ausschubstation 47. Diese liegt der Einschubstation 14 gegenüber, also in der horizontalen Mittelebene des Faltrevolvers 12.The package completed with respect to the outer tube fold (tube flaps 37, 38) now arrives with the associated pocket in the area of an extension station 47. This lies opposite the insertion station 14, that is to say in the horizontal central plane of the folding turret 12.

Im Bereich der Ausschubstation 47 ist benachbart zum Außenumfang des Faltrevolvers 12 eine Ausschubplattform 48 angeordnet. Diese wird korrespondierend zur Einschubplattform 20 in Umfangsrichtung des Faltrevolvers 12 hin- und her- bzw. auf- und abbewegt. Die weitgehend fertiggestellte Packung 24 wird während einer Phase gleicher Bewegung von Faltrevolver 12 und Ausschubplattform 48 aus der Tasche aus- und auf die Ausschubplattform 48 geschoben. Danach kehrt die Ausschubplattform 48 in eine (obere) Endstellung zurück, die gleichgerichtet ist einem Abförderer 49 in der horizontalen Mittelebene.In the area of the extension station 47, an extension platform 48 is arranged adjacent to the outer circumference of the folding turret 12. This is moved back and forth or up and down corresponding to the insertion platform 20 in the circumferential direction of the folding turret 12. The largely completed package 24 is pushed out of the pocket and pushed onto the extension platform 48 during a phase of identical movement of the folding turret 12 and extension platform 48. Thereafter, the extension platform 48 returns to an (upper) end position which is rectified to a discharge conveyor 49 in the horizontal median plane.

Bei dem vorliegenden Ausführungsbeispiel ist die Ausschubplattform 48 mit der Stapelschwinge 21 verbunden, die über die Drehachse des Faltrevolvers 12 hinaus verlängert ist und gegenüberliegend zur Einschubplattform 20 am freien Ende die Ausschubplattform 48 aufnimmt. Dadurch sind die Bewegungen von Einschubplattform 20 und Ausschubplattform 48 stets korrespondierend.In the present exemplary embodiment, the extension platform 48 is connected to the stacking rocker 21, which is extended beyond the axis of rotation of the folding turret 12 and, opposite the insertion platform 20, receives the extension platform 48 at the free end. As a result, the movements of the insertion platform 20 and the extension platform 48 are always corresponding.

Die Relativanordnung ist so getroffen, daß die Einschubplattform 20 nach Aufnahme eines Stapels 10 aufwärts und zugleich die Ausschubplattform 48 zur Beschleunigung auf die Umfangsgeschwindigkeit des Faltrevolvers 12 abwärts bewegt wird. Die übergabe der Pakkung 24 an die Ausschubplattform 48 erfolgt mithin unterhalb des Ebene des Abförderers 49. Bei der Rückkehr der Einschubplattform 20 in die Ausgangsposition wird die Ausschubplattform 48 mit der Packung aufwärtsbewegt auf das Niveau des Abförderers 49 und während einer Phase momentanen Stillstands durch einen hakenförmigen Abschieber von der Ausschubplattform 48 in Radialrichtung abgezogen und an den Abförderer 49 übergeben.The relative arrangement is such that the insertion platform 20 is moved upwards after picking up a stack 10 and at the same time the extension platform 48 is moved downwards for acceleration to the peripheral speed of the folding turret 12. The transfer of the package 24 to the delivery platform 48 therefore takes place below the level of the removal conveyor 49. When the insertion platform 20 returns to the starting position, the delivery platform 48 with the package is moved up to the level of the removal conveyor 49 and during a phase of instantaneous standstill by a hook-shaped one The pusher is pulled off the extension platform 48 in the radial direction and transferred to the discharge conveyor 49.

Jeder Tasche 13 ist ein eigener Ausschieber 51 zugeordnet. Dieser befindet sich in der zurückgezogenen Ausgangsstellung an der radialen Innenseite der Tasche 13 und bildet so den Boden derselben. Der Ausschieber 51 ist zu diesem Zweck als Leiste ausgebildet, die sich in Axialrichtung über die gesamte Länge der Tasche 13 erstreckt. Zur seitlichen Begrenzung der im übrigen offenen Taschen 13 sind am Ausschieber 51 seitlich in Radialrichtung weisende Faltdaumen 52, 53 angeordnet. Der axiale Abstand der Faltdaumen 52, 53 voneinander entspricht der Länge des Stapels 10 bzw. der Packung 24. Aufgrund der Ausbildung der Faltdaumen 52, 53 wird beim Einschieben eines Stapels 10 mit Zuschnitt 11 in eine Tasche 13 ein in Einschubrichtung vorn liegender Seitenlappen 54 gefaltet. Es handelt sich dabei um die erste Faltung einer an den Stirnseiten der Packung gebildeten, bekannten Kreuzfaltung.Each pocket 13 is assigned its own pusher 51. This is in the retracted starting position on the radial inside of the pocket 13 and thus forms the bottom thereof. For this purpose, the pusher 51 is designed as a bar which extends in the axial direction over the entire length of the pocket 13. For lateral limitation of the otherwise open pockets 13, folding thumbs 52, 53 are arranged laterally in the radial direction on the slide-out element 51. The axial spacing of the folding thumbs 52, 53 from one another corresponds to the length of the stack 10 or the pack 24. Due to the design of the folding thumbs 52, 53, when a stack 10 with blank 11 is inserted into a pocket 13, a side flap 54 lying forward in the insertion direction is folded . It is the first fold of a known cross fold formed on the end faces of the pack.

Der zum inneren Seitenlappen 54 gegenüberliegende äußere Seitenlappen 55 wird erst beim Ausschub der Packung aus der Tasche im Bereich der Ausschubstation 47 gefaltet. Zu diesem Zweck sind seitlich auf der Ausschubplattform 48 Faltdaumen 56 angeordnet, die entgegengesetzt zu den Faltdaumen 52, 53 wirken und den in Förderrichtung vorn liegenden Seitenlappen 55 beim Aufschieben der Packung 24 auf die Ausschubplattform 48 falten. Diese ist zur besseren Führung und Fixierung der Packung taschenförmig ausgebildet, nämlich mit einer Oberwand 57 als obere Führung für die Packung.The outer side flap 55 opposite the inner side flap 54 is only folded when the package is ejected from the pocket in the region of the ejection station 47. For this purpose, folding thumbs 56 are arranged laterally on the pushing-out platform 48, which act opposite to the folding thumbs 52, 53 and fold the side flaps 55 lying in the conveying direction when the pack 24 is pushed onto the pushing-out platform 48. This is pocket-shaped for better guidance and fixation of the pack, namely with an upper wall 57 as the upper guide for the pack.

Beim Einschub der Packung 24 von der Ausschubplattform 48 in den Abförderer 49 werden obere und untere Längsseitenlappen 58 gefaltet. Zu diesem Zweck sind im Eintrittsbereich des Abförderers 49 zwischen einem Unterband 59 und einem Oberband 60 seitlich Faltorgane angebracht, nämlich Faltweichen 61, durch die während des Transports der Packungen in bekannter Weise die oberen und unteren Längsseitenlappen 58 gefaltet werden. Die zuerst gefalteten Seitenlappen 54 und 55 werden in diesem Bereich durch winkelförmige Führungsorgane 62 in Position gehalten.When the package 24 is inserted from the delivery platform 48 into the discharge conveyor 49, upper and lower longitudinal side tabs 58 are folded. For this purpose, folding members, namely folding switches 61, are attached in the entry area of the discharge conveyor 49 between a lower belt 59 and an upper belt 60, by means of which the upper and lower longitudinal side tabs 58 are folded in a known manner during the transport of the packs. The first folded side tabs 54 and 55 are held in position in this area by angular guide members 62.

Zum Ausschieben einer Packung 24 aus einer Tasche 13 im Bereich der Ausschubstation 47 wird der der Tasche 13 zugeordnete Ausschieber 51 in Radialrichtung bewegt. Der Ausschieber 51 ist zu diesem Zweck an radial gerichteten Stößeln 63 angebracht. In Axialrichtung sind jedem Ausschieber 51 zwei derartiger Stößel 63 im Abstand voneinander angeordnet und innerhalb des Revolvers 12 in Führungen 64 gleitend gehalten. Die Radialbewegung der Ausschieber 51 wird durch seitliche Kurvenscheiben 65 bewirkt, in denen eine Steuernut 66 gebildet ist. In dieser wiederum läuft eine jedem Ausschieber 51 zugeordnete Führungsrolle 67 ab. Bei dem gezeigten Ausführungsbeispiel sitzt an den beiden Enden einer die Stößel 63 miteinander verbindenden Querstange 68 jeweils eine Führungsrolle 67.To push a pack 24 out of a pocket 13 in the region of the push-out station 47, the push-out member 51 assigned to the pocket 13 is moved in the radial direction. For this purpose, the pusher 51 is attached to radially directed plungers 63. In the axial direction, each pusher 51 has two such plungers 63 at a distance from one another and is slidably held in guides 64 within the turret 12. The radial movement of the pusher 51 is effected by side cam plates 65, in which a control groove 66 is formed. In this turn, a guide roller 67 assigned to each pusher 51 runs. In the exemplary embodiment shown, a guide roller 67 is seated at the two ends of a cross rod 68 connecting the plungers 63 to one another.

Die Steuernut 66 der Kurvenscheibe 65 ist während des überwiegenden Bereichs konzentrisch zum Faltrevolver 12 geformt, so daß sich die Ausschieber 51 in der zurückgezogenen, inneren Position befinden. Im Bereich der Ausschubstation 47, und zwar unterhalb derselben, bildet die Steuernut eine radiale Ausbuchtung 69. Diese bewirkt den Ausstoßhub des Ausschiebers 51, wenn Tasche 13 und Ausschubplattform 48 benachbart zueinander mit gleicher Geschwindigkeit umlaufen.The control groove 66 of the cam disk 65 is shaped concentrically to the folding turret 12 during the predominant area, so that the pushers 51 are in the retracted, inner position. The control groove forms a radial bulge 69 in the area of the push-out station 47, namely below the same. This causes the push-out stroke of the push-out member 51 when the pocket 13 and push-out platform 48 run adjacent to one another at the same speed.

Die Schwenkbewegungen der Stapelschwinge 21 und damit der Einschubplattform 20 und der Ausschubplattform 48 sind auf eine Bewegungsamplitude (Pfeile 70) von 18° ausgerichtet. Wie aus Fig. 6 ersichtlich, ist eine Beschleunigungsphase von im vorliegenden Falle 4° und eine Gleichlaufphase 72 von 10° vorgesehen. Während dieser erfolgt die Übergabe der Stapel 10 bzw. Packungen 24 in die Tasche 13 bzw. aus dieser.The pivoting movements of the stacking rocker 21 and thus the insertion platform 20 and the extension platform 48 are aligned with a movement amplitude (arrows 70) of 18 °. As can be seen from FIG. 6, an acceleration phase of 4 ° in the present case and a synchronization phase 72 of 10 ° are provided. During this, the stacks 10 or packs 24 are transferred into or out of the pocket 13.

Wie weiterhin aus Fig. 6 ersichtlich, wird zur Beschleunigung des Ausschubvorgangs während dieser Phase die Kurvenscheibe 65 zusätzlich in gegenläufigem Sinne zum Faltrevolver verschwenkt, so daß die Ausbuchtung 69 der Steuernut 66 aus der in Fig. 6 strichpunktierten Ausgangsstellung in die in ausgezogenen Linien gezeigte Stellung gelangt. Dadurch ergibt sich eine schnelle, kurzfristige Radialbewegung der Stößel 63 während der Gleichlaufphase 72.As can furthermore be seen from FIG. 6, the cam plate 65 is additionally pivoted in the opposite direction to the folding turret in order to accelerate the extension process, so that the bulge 69 of the control groove 66 from the starting position shown in broken lines in FIG. 6 into the position shown in solid lines reached. This results in a rapid, short-term radial movement of the plunger 63 during the synchronous phase 72.

Die hier gezeigte Vorrichtung ist zur Erhöhung der Leistungsfähigkeit für zweibahnigen Betrieb eingerichtet. Es werden demnach gleichzeitig zwei Stapel 10 durch zwei parallele Zuförderer 15 dem Faltrevolver 12 zugeführt. Dieser ist in Axialrichtung so bemessen, daß die beiden Stapel 10 nebeneinander in einer gemeinsamen, durchgehend offenen Tasche 13 Aufnahme finden können. Der Faltrevolver 12 ist im vorliegenden Fall als Hohlkörper nach dem Konstruktionsprinzip der Garnrolle ausgebildet mit einem zylindrischen Revolvermantel 73 und einer etwa mittigen radialen Abstützung 74 auf einer drehenden Nabe 75. An einem Rand des Revolvermantels 73 ist ein radial nach innen gerichteter Flansch 76 gebildet, der mit einer ringsherum laufenden Innenverzahnung 77 für den Eingriff eines Antriebsritzel 78 ausgebildet ist.The device shown here is for increasing the performance for two-lane operation set up. Accordingly, two stacks 10 are simultaneously fed to the folding turret 12 by two parallel feed conveyors 15. This is dimensioned in the axial direction so that the two stacks 10 can be accommodated next to one another in a common, continuously open pocket 13. The folding turret 12 is formed in the present case as a hollow body according to the construction principle of the spool of thread with a cylindrical revolver casing 73 and an approximately central radial support 74 on a rotating hub 75. A radially inwardly directed flange 76 is formed on an edge of the revolving casing 73, is formed with an internal toothing 77 running all around for the engagement of a drive pinion 78.

Innerhalb des Revolvermantels 73 befindet sich jeweils an den Seiten eine Kurvenscheibe 65. Beide Kurvenscheiben sind über eine Hohlwelle 79 miteinander verbunden. Eine der Kurvenscheiben 65 (in Fig. 2 oben dargestellt) wird durch einen Kurbeltrieb 80 schwingend angetrieben, um die in Zusammenhang mit Fig. 6 beschriebene Ausschubbewegung zu bewirken. Die Kurvenscheiben 65 werden durch die Hohlwelle 79 gemeinsam bewegt.A cam disk 65 is located on each side of the revolver jacket 73. Both cam disks are connected to one another via a hollow shaft 79. One of the cam disks 65 (shown in FIG. 2 above) is oscillatingly driven by a crank mechanism 80 in order to bring about the extension movement described in connection with FIG. 6. The cam discs 65 are moved together by the hollow shaft 79.

Innerhalb des Revolvermantels 73 befinden sich auch die Stößel 63 zur Betätigung der Ausschieber 51. Die Führungen 64 sind mit den Abstützungen 74 verbunden.The tappets 63 for actuating the pushers 51 are also located within the turret casing 73. The guides 64 are connected to the supports 74.

Die Ausschieber 51 erstrecken sich über die volle axiale Länge der Taschen 13 zur Aufnahme von zwei Stapeln 10. Jeder leistenförmige Ausschieber 51 ist demnach mit zwei Paaren von Faltdaumen 52, 53 versehen.The pushers 51 extend over the full axial length of the pockets 13 for receiving two stacks 10. Each strip-shaped pushers 51 is accordingly provided with two pairs of folding thumbs 52, 53.

Die Einschubplattform 20 (Fig. 4) ist einstückig ausgebildet und mit einer Breite für die Aufnahem von zwei Stapeln 10. Die Position derselben auf der in Axialrichtung durchgehenden Einschubplattform 20 ist durch Seitenführungen 81, 82 gewährleistet, die auf der Eintrittsseite mit einer Einlauffase 83 und auch mit einer Oberfase 84 ausgebildet sind. Der Pendelantrieb der Stapelschwinge 21 ist auf der Seite der Einschubplattform 20 unterhalb derselben angebracht. Hier greift mittig ein Hebel 85 als Teil eines Kurbelantriebs 86 an.The insertion platform 20 (FIG. 4) is formed in one piece and has a width for receiving two stacks 10. The position thereof on the insertion platform 20 which is continuous in the axial direction is ensured by side guides 81, 82 which have an inlet chamfer 83 and are also formed with an upper chamfer 84. The pendulum drive of the stacking arm 21 is mounted on the side of the slide-in platform 20 below it. Here lever 85 engages in the middle as part of a crank drive 86.

In besonderer Weise sind auch die Einschieber 23 für die beiden Fertigungsbahnen ausgerichtet. Zwei derartige Einschieber 23 sind durch eine obere Traverse 87 miteinander verbunden. Jeder Einschieber 23 ist dreigeteilt durch aufrechte Schlitze 88. Diese sind so angeordnet, daß bei zurückgezogenem Einschieber 23 der entsprechend gabelförmig ausgebildete Mitnehmer 16 des Zuförderers 15 bis in den Bereich des Einschiebers 23 laufen kann, indem nämlich der gabelförmige Mitnehmer 16 durch die Schlitze 88 hindurchtritt.The pushers 23 are also aligned in a special way for the two production lines. Two such pushers 23 are connected to each other by an upper cross member 87. Each pusher 23 is divided into three by upright slots 88. These are arranged such that when the pusher 23 is retracted, the correspondingly fork-shaped driver 16 of the feed conveyor 15 can run into the area of the pusher 23, namely by the fork-shaped driver 16 passing through the slots 88 .

Den beiden Fertigungsbahnen zugeordnete Preßplatten 22 sind an der Unterseite eines sich in Axialrichtung erstreckenden Tragbalkens 89 angeordnet. An dessen seitliche Enden schließt jeweils die Preßschwinge 25 an, die sich demnach mit zwei Schwingarmen 90, 91 zu beiden Seiten des Faltrevolvers 12 erstreckt und drehbar in einer Lagervertiefung 92 der Hohlwelle 79 gelagert ist. Die Preßschwinge 25 bzw. deren Schwingarme 90, 91 sind über das vorgenannte Lager, also über den Drehmittelpunkt des Faltrevolvers 12 hinaus verlängert. Auf der zur Einschubstation 14 gegenüberliegenden Seite sind die Enden der Schwingarme 90, 91 durch eine Querstange 93 miteinander verbunden. An dieser greift etwa in der Mitte ein Schwenkantrieb für die Preßschwinge 25 an, nämlich ein Kurbeltrieb 94. Die Schwingarme 90, 91 erstrecken sich als aufrechte Schenkel an der Oberseite des Tragbalkens 89. Beide Schwingarme 90, 91 sind im Bereich der Einschubplattform mit einem Langloch 26 für die Führungsrolle 27 der Einschieber 23 versehen. Deren quergerichtete Traverse 87 ist zu diesem Zweck mit abwärts gerichteten Schenkeln 95 versehen, an deren Innenseite jeweils die Führungsrolle 27 angebracht ist.Press plates 22 assigned to the two production lines are arranged on the underside of a support beam 89 extending in the axial direction. At the lateral ends of each press rocker 25 connects, which accordingly extends with two swing arms 90, 91 on both sides of the folding turret 12 and is rotatably mounted in a bearing recess 92 of the hollow shaft 79. The press rocker 25 or its swing arms 90, 91 are extended beyond the aforementioned bearing, that is to say beyond the center of rotation of the folding turret 12. On the side opposite the insertion station 14, the ends of the swing arms 90, 91 are connected to one another by a crossbar 93. A swivel drive for the press rocker 25, namely a crank drive 94, engages about this in the middle. The swing arms 90, 91 extend as an upright leg on the upper side of the support beam 89. Both swing arms 90, 91 are in the region of the insertion platform with an elongated hole 26 provided for the guide roller 27 of the slider 23. For this purpose, their transverse crossmember 87 is provided with legs 95 pointing downward, on the inside of which the guide roller 27 is attached in each case.

Den Einschiebern 23 bzw. der gemeinsamen Traverse 87 sind als Fortsatz der Schenkel 95 zwei seitlich neben dem Faltrevolver 12 verlaufende Lenker 28 zur gemeinsamen Betätigung der beiden Einschieber 23 zugeordnet. Deren Enden wiederum sind jeweils mit einem Kurbelarm 29 verbunden. Beide Kurbelarme 29 werden durch eine gemeinsame Antriebswelle 96 schwingend angetrieben, die drehbar in er Hohlwelle 79 gelagert ist.As an extension of the legs 95, the pushers 23 and the common traverse 87 are assigned two links 28 extending laterally next to the folding turret 12 for the joint actuation of the two pushers 23. The ends of which are each connected to a crank arm 29. Both crank arms 29 are oscillatingly driven by a common drive shaft 96 which is rotatably mounted in the hollow shaft 79.

Die Hohlwelle 79 bzw. deren Lagervertiefung 92 dient auch zur drehbaren Lagerung der ebenfalls zu beiden Seiten des Faltrevolvers 12 verlaufenden Stapelschwingen 21. Schließlich befindet sich in der beiden Lagervertiefungen 92 jeweils ein Lagerbock 97 als Traggestell bzw. Maschinengestell des Faltrevolvers 12.The hollow shaft 79 or its bearing recess 92 is also used for the rotatable mounting of the stacking arms 21, which also run on both sides of the folding turret 12. Finally, in the two bearing recesses 92 there is a bearing block 97 as the supporting frame or machine frame of the folding turret 12.

Zur Bildung einer exakten Packung 24 ist im Bereich der Einschubstation 14 eine sich nach unten längs eines Teilumfangs des Faltrevolvers 12 erstreckende Schürze 98 angeordnet, die sich eng an den Umfang des Faltrevolvers 12 anschmiegt. Die Schürze 98 ist in Höhe der Einschubplattform 20 für den Durchtritt des Stapels 10 mit einem Fenster 99 versehen. Die Schürze 98 ist an der Preßplatte 22, nämlich an der Unterseite derselben, angebracht und wird folglich mit dieser auf- und abbewegt.In order to form an exact package 24, an apron 98 which extends down along a partial circumference of the folding turret 12 is arranged in the region of the insertion station 14 and clings closely to the circumference of the folding turret 12. The apron 98 is provided with a window 99 at the level of the insertion platform 20 for the passage of the stack 10. The apron 98 is attached to the press plate 22, namely on the underside thereof, and is consequently moved up and down with it.

Auch die Seite der Ausschubstation 47 ist auf den zweibahnigen Betrieb ausgerichtet. Wie aus Fig. 5 ersichtlich, ist für beide Fertigungsbahnen eine gemeinsame, durchgehende Ausschubplattform 48 vorgesehen, die durch die Oberwand 57 und Seitenwände mit Faltdaumen 56 in geschlossene Ausschubtaschen 100, 101 unterteilt ist. Zwei den Ausschubtaschen 100, 101 zugeordnete, hakenförmige Abschieber 50 sind durch einen Querbügel 102 zu einem gemeinsamen Gebilde verbunden. Es werden demnach stets zwei Packungen 24 von der Ausschubplattform 48 abgezogen. die Oberwand 57 ist mit Schlitzen 103 für den Durchgang des Querbügels 102 versehen.The side of the extension station 47 is also designed for two-lane operation. As can be seen from FIG. 5, a common, continuous extension platform 48 is provided for both production lines, which is divided into closed extension pockets 100, 101 by the top wall 57 and side walls with folding thumbs 56. Two ha assigned to the extension pockets 100, 101 Ken-shaped pushers 50 are connected by a crossbar 102 to form a common structure. Accordingly, two packs 24 are always withdrawn from the delivery platform 48. the top wall 57 is provided with slots 103 for the passage of the crossbar 102.
