Description

Die Erfindung betrifft eine Verpackungsmaschine zur Herstellung von Verpackungen, insbesondere Zigaretten-Verpackungen, aus bahnförmigem Verpackungsmaterial, welches von einer Arbeits-Bobine auf einem Arbeitszapfen abgezogen wird, wobei eine neue "volle" Bobine durch einen Transportzapfen einem Bobinen-Vorrat entnommen, in axialer Ausrichtung vor den Arbeitszapfen gefördert und durch axiales Verschieben auf diesen übertragen wird.The invention relates to a packaging machine for producing packaging, in particular cigarette packaging, from sheet-like packaging material which is pulled off a working bobbin on a working pin, a new "full" bobbin being taken from a bobbin stock by a transport pin, in axial alignment conveyed in front of the working pin and transferred to it by axial displacement.

Verpackungsmaschinen mit hoher Leistung, insbesondere Zigaretten-Verpackungsmaschinen, haben einen entsprechend hohen Verbrauch an Verpackungsmaterial. Dieses wird- außer bei der Zuführung von anderweitig gefertigten Einzel-Zuschnitten - als bahnförmiges Material in gewickelten Bobinen der Verpackungsmaschine zur Verfügung gestellt. Daraus werden dann Zuschnitte innerhalb der Verpackungsmaschine gefertigt und verarbeitet.High-performance packaging machines, especially cigarette packaging machines, have a correspondingly high consumption of packaging material. This is - aside from the feeding of otherwise manufactured individual blanks - as a web-like material in wound bobbins made available to the packaging machine. From this, blanks are then manufactured and processed within the packaging machine.

Angesichts des erheblichen Verbrauchs an Verpackungsmaterial ist es wichtig, Bobinen in ausreichender Zahl und in günstiger Position zur Verfügung zu stellen. Weiterhin ist es wichtig, neue, also "volle" Bobinen über kurze Förderstrecken der Verarbeitungsstation, nämlich Arbeitszapfen, zuzuführen.In view of the considerable consumption of packaging material, it is important to provide bobbins in sufficient numbers and in a convenient position. It is also important to feed new, ie "full" bobbins to the processing station, namely working spigots, over short conveying distances.

Bei einer bekannten Vorrichtung für die Zuführung von Bobinen von einem Bobinen-Vorrat zu einem Arbeitszapfen ist ein Kipphebel mit Transportzapfen durch Spindeltrieb längs einer geradlinigen Förderstrecke verfahrbar. Für die Übernahme einer Bobine aus dem Bobinen-Vorrat sowie zur Übergabe derselben an den Arbeitszapfen wird der Kipphebel mit der Bobine quer zur Förderebene verschwenkt (DE-OS 32 02 647).In a known device for feeding bobbins from a bobbin supply to a working pin, a rocker arm with transport pin can be moved along a straight conveying path by a spindle drive. To take a bobbin from the bobbin stock and to transfer it to the working pin, the rocker arm is pivoted with the bobbin transversely to the conveying plane (DE-OS 32 02 647).

Durch den linearen Transport der "vollen" Bobine vom Bobinen-Vorrat zum Arbeitszapfen müssen verhältnismäßig lange Transportwege mit entsprechendem Zeitaufwand zurückgelegt werden. Die Leistungsfähigkeit dieser bekannten Bobinen-Wechselvorrichtung ist dadurch geringer.Due to the linear transport of the "full" bobbin from the bobbin stock to the work spigot, relatively long transport routes have to be covered with a corresponding amount of time. The performance of this known bobbin changing device is therefore lower.

Der Erfindung liegt die Aufgabe zugrunde, bei einer Verpackungsmaschine für die Verarbeitung von Bobinen bahnförmigen Verpackungsmaterials die Bobinen-Wechselvorrichtung so auszubilden, daß abgelaufene, "leere" (Arbeits-)Bobinen innerhalb kürzester Zeit gegen neue, "volle" Bobinen ausgewechselt werden können, ohne daß dabei der Betrieb der Verpackungsmaschine unterbrochen werden muß.The invention has for its object to design the bobbin changing device in a packaging machine for processing bobbins of sheet-like packaging material so that expired, "empty" (working) bobbins can be exchanged for new, "full" bobbins within a very short time without that the operation of the packaging machine must be interrupted.

Zur Lösung dieser Aufgabe ist die erfindungsgemäße Verpackungsmaschine bzw. deren Bobinen-Wechselvorrichtung dadurch gekennzeichnet, daß der Transportzapfen an einem Transportarm angeordnet ist, der schwenkbar zwischen Bobinen-Vorrat und Arbeitszapfen gelagert ist und jeweils eine ("volle") Bobine längs eines Kreisbogens alternativ vor eine von mehreren, insbesondere zweien, Arbeitszapfen fördert.To achieve this object, the packaging machine according to the invention or its bobbin changing device is characterized in that the transport pin on one Transport arm is arranged, which is pivotally mounted between the bobbin stock and working spigot and in each case promotes one ("full") bobbin along a circular arc alternatively in front of one of several, in particular two, working spigots.

Bei der erfindungsgemäßen Verpackungsmaschine sind demnach zwei Arbeitszapfen vorgesehen, vorzugsweise in gemeinsamer horizontaler Ebene mit Abstand nebeneinanderliegend. Das bahnförmige Verpackungsmaterial wird zur Herstellung von Zuschnitten jeweils von einem der beiden Arbeitszapfen abgezogen. Der andere ist für den Wechsel einer leergefahrenen Bobine gegen eine "volle" Bobine bereit. Die Übergabe derselben von einem Bobinen-Vorrat erfolgt erfindungsgemäß durch einen schwenkbaren Transportarm, der so relativ zu den Arbeitszapfen gelagert ist, daß durch kurze Schwenkbewegungen die neue Bobine vor den einen oder anderen Arbeitszapfen gefördert werden kann. Die Übergabe erfolgt zweckmäßigerweise von Hand, da Transportzapfen und Arbeitszapfen gleichachsig ausgerichtet und lediglich ein sehr kurzer axial gerichteter Förderweg zu überwinden ist.Accordingly, two working pins are provided in the packaging machine according to the invention, preferably lying next to one another at a distance in a common horizontal plane. The sheet-like packaging material is pulled off one of the two working pins to produce blanks. The other is ready to change an empty bobbin for a "full" bobbin. The transfer of the same from a bobbin stock takes place according to the invention by a pivotable transport arm which is mounted relative to the working spigot that the new bobbin can be conveyed in front of one or the other working spigot by short pivoting movements. The transfer is expediently carried out by hand, since the transport pin and the working pin are aligned on the same axis and only a very short axially directed conveying path has to be overcome.

Der Bobinen-Vorrat, insbesondere ein muldenförmiges, langgestrecktes Traggestell, ist vorzugsweise oberhalb der Arbeitszapfen, nämlich oberhalb der weiteren Konstruktionsteile der Verpackungsmaschine, angeordnet, wobei die bevorrateten Bobinen axial ausgerichtet nebeneinandergestellt sind. Dadurch ist an räumlich günstiger Stelle ein verhältnismäßig großer Vorrat zu errichten, ohne daß die Verpackungsmaschine im übrigen beeinträchtigt wird. Das Traggestell kann von der Rückseite der Verpackungsmaschine her leicht mit neuen Bobinen beschickt werden.The bobbin stock, in particular a trough-shaped, elongated support frame, is preferably arranged above the working spigot, namely above the other structural parts of the packaging machine, the stocked bobbins being axially aligned. As a result, a comparatively large stock can be built at a spatially advantageous location without the packaging machine being otherwise impaired. The support frame can be easily loaded with new bobbins from the back of the packaging machine.

Der Transportarm als Überführungsorgan für die "vollen" Bobinen vom Vorrat zu den Arbeitszapfen ist mittig zwischen den Transportzapfen gelagert, so daß kurze Schwenkbewegungen zur einen und anderen Seite die Zustellung der Bobinen ermöglichen. Darüber hinaus ist der Transportarm mit dem Transportzapfen in dessen Axialrichtung verschiebbar zur Übernahme der Bobine aus dem gegenüber den Arbeitszapfen zurückgesetzten Vorrat.The transport arm as a transfer element for the "full" bobbins from the supply to the work spigot is mounted centrally between the transport spigots, so that short swiveling movements to one side and the other allow the bobbins to be delivered. In addition, the transport arm slidable in the axial direction with the transport pin for taking over the bobbin from the supply set back from the working pin.

The material web is drawn off from a work reel 12 and processed to produce blanks.

Für die Aufnahme von Arbeitsbobinen 12 sind bei dem vorliegenden Ausführungsbeispiel zwei Arbeitszapfen 13, 14 vorgesehen, die in gemeinsamer Horizontalebene mit Abstand voneinander an einem Maschinengestell 15 gelagert sind. Die Arbeitszapfen 13, 14 sind frei auskragend, einseitig gelagert und durch nicht näher gezeigte Organe innerhalb des Maschinengestells 15 drehend angetrieben. Die Bobinen 11 bzw. Arbeitsbobinen 12 sind mit einem Mittelloch 16 versehen, welches zu den Abmessungen der Arbeitszapfen 13, 14 paßt, so daß die Bobinen 11 bzw. Arbeitsbobinen 12 in Axialrichtung auf die Arbeitszapfen 13, 14 geschoben werden können. Üblicherweise sind die Bobinen 11, 12 mit einem Bobinenkern in Gestalt einer Papphülse (nicht näher gezeigt) versehen, die nach Verbrauch einer Arbeitsbobine 12 vom Arbeitszapfen 13, 14 (manuell) abgezogen wird. Von den Arbeitszapfen 13, 14 befindet sich jeweils einer in Arbeitsstellung. Von diesem wird das Verpackungsmaterial als Materialbahn 17 abgezogen (Arbeitszapfen 14 in Fig. 4), während der andere Arbeitszapfen 13 für die Aufnahme bzw. Bereithaltung einer neuen, "vollen" Bobine 11 vorgesehen ist.In the present exemplary embodiment, two working pins 13, 14 are provided for receiving work bobbins 12, which are mounted on a machine frame 15 at a distance from one another in a common horizontal plane. The working pins 13, 14 are freely cantilevered, supported on one side and driven in rotation within the machine frame 15 by organs (not shown). The bobbins 11 or work bobbins 12 are provided with a center hole 16 which matches the dimensions of the work pins 13, 14, so that the bobbins 11 or work bobbins 12 can be pushed onto the work pins 13, 14 in the axial direction. The bobbins 11, 12 are usually provided with a bobbin core in the form of a cardboard sleeve (not shown in more detail), which is (manually) drawn off from the working pin 13, 14 after a working bobbin 12 has been used up. One of the working pins 13, 14 is in the working position. The packaging material is drawn off from this as material web 17 (working pin 14 in FIG. 4), while the other working pin 13 is provided for receiving or holding a new, "full" bobbin 11.

Der Verpackungsmaschine 10 bzw. der Bobinen-Wechselvorrichtung ist ein Bobinen-Vorrat 18 zugeordnet. Dieser ist bei dem vorliegenden Ausführungsbeispiel oberhalb der Verpackungsmaschine 10 bzw. oberhalb des Maschinengestells 15 angeordnet. Der Bobinen-Vorrat 18 besteht im wesentlichen aus einem langgestreckten Traggestell 19, welches sich horizontal quer zur Längsausdehnung der Verpackungsmaschine 10 erstreckt. Der überwiegende Teil des Traggestells 19 befindet sich an der Rückseite der Verpackungsmaschine 10, bei dem Ausführungsbeispiel gemäß Fig. 3 mit einer Stütze 20 am freien Ende. Auf dem Traggestell 19 sind Bobinen 11 in einer größeren Anzahl in parallelen Ebenen und axialer Ausrichtung angeordnet, wobei die Bobinen 11 mit ihrer Umfangsfläche unten auf dem Traggestell 19 aufstehen. Eine jeweils vornstehende bzw. den Arbeitszapfen 13 am nächsten liegende Bobine 11a ist für die Entnahme und Zuführung zu einem der Arbeitszapfen 13, 14 bereit.A packaging stock 18 is associated with the packaging machine 10 or the bobbin changing device. In the present exemplary embodiment, this is arranged above the packaging machine 10 or above the machine frame 15. The bobbin stock 18 consists essentially of an elongated support frame 19 which extends horizontally across the longitudinal extent of the packaging machine 10. The majority of the support frame 19 is located on the back of the packaging machine 10, 3 with a support 20 at the free end. A large number of bobbins 11 are arranged on the support frame 19 in parallel planes and in an axial orientation, the bobbins 11 standing up on the support frame 19 with their peripheral surface. A bobbin 11a, which is in front or closest to the work pin 13, is ready for removal and delivery to one of the work pins 13, 14.

Als Transportorgan für die Übernahme einer Bobine 11a aus dem Bobinen-Vorrat 18 und zur Übergabe an einen der beiden Arbeitszapfen 13, 14 dient ein Transportarm 21. An diesem ist im oberen Bereich ein frei abstehender, einseitig gelagerter Transportzapfen 22 angebracht, der ebenfalls zu den Abmessungen des Mittellochs 16 paßt.A transport arm 21 is used as the transport member for taking over a bobbin 11a from the bobbin supply 18 and for transferring it to one of the two working pins 13, 14. A free-standing, one-sided mounted transport pin 22 is attached to this in the upper area, which also belongs to the Dimensions of the center hole 16 fits.

Der Transportarm 21 ist in besonderer Weise gelagert und antreibbar. Der Bobinen- Vorrat 18 ist gegenüber der vertikalen Drehebene der Arbeitsbobinen 12 zur Rückseite der Verpackungsmaschine versetzt. Zur Aufnahme einer "vollen" Bobine 11a aus dem Bobinen-Vorrat 18 ist deshalb der Transportarm 21 in Axialrichtung des Transportzapfens 22 verfahrbar, so daß dieser durch Eintritt in das Mittelloch 16 der Bobine 11a diese aufzunehmen vermag.The transport arm 21 is mounted and driven in a special way. The reel stock 18 is offset from the vertical rotational plane of the work reels 12 to the rear of the packaging machine. To receive a "full" bobbin 11a from the bobbin stock 18, the transport arm 21 can therefore be moved in the axial direction of the transport pin 22, so that it can accommodate the bobbin 11a by entering the center hole 16 thereof.

Mit der auf dem Transportzapfen 22 gehaltenen Bobine 11a wird der Transportarm 21 in entgegengesetzter Richtung verfahren, bis sich die Bobine 11a in einer Ebene vor den Arbeitsbobinen 12 bzw. den Arbeitszapfen 13, 14 befindet. Durch Verschwenken des Transportarms 21 in dieser Ebene längs eines Viertelkreisbogens wird die Bobine 11a vor den einen oder anderen Arbeitszapfen 13, 14 gefahren, und zwar in Axialrichtung auf diesen ausgerichtet. In dieser Stellung wird die Bobine 11a auf den leeren Arbeitszapfen durch Axialverschiebung übergeben, wie in Fig. 2 anhand des Arbeitszapfens 13 gezeigt. Die Übergabe erfolgt zweckmäßigerweise manuell.With the bobbin 11a held on the transport pin 22, the transport arm 21 is moved in the opposite direction until the bobbin 11a is located in one plane in front of the work bobbins 12 or the work pins 13, 14. By pivoting the transport arm 21 in this plane along a quarter-circle arc, the bobbin 11a is moved in front of one or the other of the working pins 13, 14, specifically in the axial direction. In this position, the bobbin 11a is transferred to the empty work pin by axial displacement, as shown in FIG. 2 with the help of the work pin 13. The transfer is advantageously carried out manually.

Der Transportarm 21 wird nunmehr aus der horizontal gerichteten Übergabeposition (Fig. 2) in die aufrechte Mittelstellung (Fig. 3, 4) zurückgeschwenkt. Durch Verschieben in Axialrichtung wird der Transportzapfen 22 in Richtung auf den Bobinen-Vorrat 18 zur Übernahme der nächsten Bobine 11a bewegt.The transport arm 21 is now pivoted back from the horizontally directed transfer position (FIG. 2) into the upright middle position (FIGS. 3, 4). By shifting in the axial direction, the transport pin 22 is moved in the direction of the reel stock 18 for taking over the next reel 11a.

Der Transportarm 21 ist zur Durchführung der beschriebenen Bewegungen an einem Betätigungsgestell 23 gelagert, welches in Fig. 2 als axial verschiebbare und drehbare Stange dargestellt ist. Wie aus Fig. 3 und 5 ersichtlich, besteht das Betätigungsgestell 23 aus einer langgestreckten Tragstange 24, die axial verschiebbar im Maschinengestell 15 gelagert ist. Die horizontal gerichtete Tragstange 24 ist im oberen Querschnittsbereich teilzylindrisch ausgebildet und mit einem unteren rechteckigen Ansatz 25 versehen. Letzterer ist an der Unterseite als Zahnstange 26 ausgebildet. Diese steht in Eingriff mit einem Ritzel 27, welches über eine Antriebswelle 28 (Fig. 4) durch einen hier nicht gezeigten Motor drehend in der einen oder anderen Richtung antreibbar ist.The transport arm 21 is mounted on an actuating frame 23 for carrying out the movements described, which is shown in FIG. 2 as an axially displaceable and rotatable rod. As can be seen from FIGS. 3 and 5, the actuating frame 23 consists of an elongated support rod 24 which is axially displaceably mounted in the machine frame 15. The horizontally directed support rod 24 is partially cylindrical in the upper cross-sectional area and provided with a lower rectangular extension 25. The latter is designed as a rack 26 on the underside. This is in engagement with a pinion 27 which can be driven in a rotating manner in one direction or the other via a drive shaft 28 (FIG. 4) by a motor (not shown here).

Die Tragstange 24 ist an ihren Enden mit aufwärts gerichteten Tragschenkeln 29, 30 ausgebildet. In diesen sind Enden einer Drehstange 31 drehbar gelagert. Ein freies Lagerende 32 - auf der den Arbeitszapfen 13, 14 zugekehrten Seite des Maschinengestells 15 - ist durch den Tragschenkel 29 hindurchgeführt und mit einem unteren Bereich des Transportarms 21 verbunden. Eine Drehbewegung der Drehstange 31 um die eigene Längsachse bewirkt demnach eine entsprechende Schwenkbewegung des Transportarms 21 in der einen oder anderen Richtung.The support rod 24 is formed at its ends with upward support legs 29, 30. Ends of a rotary rod 31 are rotatably mounted in these. A free bearing end 32 - on the side of the machine frame 15 facing the working pin 13, 14 - is guided through the support leg 29 and connected to a lower region of the transport arm 21. A rotary movement of the rotary rod 31 about its own longitudinal axis accordingly results in a corresponding pivoting movement of the transport arm 21 in one direction or the other.

Die Drehstange 31 ist axial verschiebbar, jedoch unverdrehbar in einer Führungshülse 33 im Maschinengestell 15 gelagert. Die drehfeste Führung der Drehstange 31 in der Führungshülse 33 wird hier durch Nuten und Federn (Fig. 4) bewirkt.The rotary rod 31 is axially displaceable but non-rotatably mounted in a guide sleeve 33 in the machine frame 15. The rotationally fixed guidance of the rotary rod 31 in the guide sleeve 33 is here by grooves and tongues (Fig. 4) causes.

Die Führungshülse 33 ist ihrerseits drehbar, jedoch axial unverschiebbar in dem Maschinengestell 15 angeordnet. An einem aus dem Maschinengestell 15 herausragenden Ende der Führungshülse 33 ist ein Zahnrad 34 angeordnet. Dieses wird über ein Zwischenzahnrad 35 von einem Antriebsmotor 36 mit Ritzel 37 drehend angetrieben. Das Zwischenzahnrad 35 ist als Zahnring auf einem Ansatz 38 des Maschinengestells 15 drehbar gelagert. Die Tragstange 24 tritt durch den hohlen Ansatz 38 hindurch. Durch reversierbaren Antrieb des Antriebsmotors 36 wird demnach der Transportarm 21 in der einen oder anderen Richtung verschwenkt, und zwar durch entsprechenden Drehantrieb der Drehstange 31. Diese ist hier mittig zwischen den Arbeitszapfen 13, 14 gelagert, auf gleicher Höhe mit diesen.The guide sleeve 33 is in turn rotatable, but axially immovable in the machine frame 15. A gearwheel 34 is arranged on an end of the guide sleeve 33 protruding from the machine frame 15. This is driven in rotation via an intermediate gear 35 by a drive motor 36 with pinion 37. The intermediate gear 35 is rotatably mounted as a toothed ring on a shoulder 38 of the machine frame 15. The support rod 24 passes through the hollow extension 38. The transport arm 21 is accordingly pivoted in one direction or the other by reversible drive of the drive motor 36, specifically by means of a corresponding rotary drive of the rotary rod 31. This is mounted here centrally between the working pins 13, 14, at the same height as these.

Das Traggestell 19 für den Bobinen-Vorrat 18 ist so ausgebildet, daß an der vorderen Entnahmeseite für die Bobine 11a ein erhöhter Endanschlag 39 gebildet ist. Die vordere Bobine 11a muß deshalb zunächst leicht angehoben werden, bevor sie aus dem Traggestell 19 herausgenommen werden kann. Zu diesem Zweck ist der Transportzapfen 22 verstellbar am Transportarm 21 gelagert, und zwar in Längsrichtung des Transportarms 21. Dadurch sind auch eventuelle Einstellungen auf unterschiedliche Positionen der Arbeitszapfen 13 und 14 möglich.The support frame 19 for the bobbin stock 18 is designed such that an elevated end stop 39 is formed on the front removal side for the bobbin 11a. The front bobbin 11a must therefore first be raised slightly before it can be removed from the support frame 19. For this purpose, the transport pin 22 is adjustably mounted on the transport arm 21, namely in the longitudinal direction of the transport arm 21. This also makes possible adjustments to different positions of the working pins 13 and 14 possible.

Bei dem vorliegenden Ausführungsbeispiel ist der Transportzapfen 22 an einem Tragkörper 40 angebracht, der entlang einer festen Führung verkantungsfrei innerhalb des einseitig offenen, als Hohlkörper ausgebildeten Transportarms 21 verfahrbar ist. Die Führung besteht hier aus seitlichen, fest an Seitenwandungen 41 angebrachten Führungsstangen 42. Diese bestehen aus Rundmaterial. Am Tragkörper 40 angebrachte Stützrollen 43, 44 liegen mit gewölbten Laufflächen formschlüssig an den Führungsstangen 42 an.In the present exemplary embodiment, the transport pin 22 is attached to a support body 40 which can be moved along a fixed guide without tilting within the transport arm 21 which is open on one side and is designed as a hollow body. The guide here consists of lateral guide rods 42 fixedly attached to side walls 41. These consist of round material. Support rollers 43, 44 attached to the supporting body 40 bear positively on the guide rods 42 with curved running surfaces.

Der Tragkörper 40 ist vier derartigen Stützrollen 43, 44 versehen, die je paarweise an einer Führungsstange 42 anliegen.The support body 40 is provided with four such support rollers 43, 44, each of which rests in pairs on a guide rod 42.

Zur Verstellung des Tragkörpers 40 in Längsrichtung des Transportarms 21 ist innerhalb desselben drehbar eine Spindel 45 gelagert. Diese wird durch einen ebenfalls innerhalb des Transportarms 21 gelagerten Stellmotor 46 drehend angetrieben. Der Tragkörper 40 ist mit einem als Spindelmuttel 47 dienenden Vorsprung auf der Spindel 45 gelagert.To adjust the support body 40 in the longitudinal direction of the transport arm 21, a spindle 45 is rotatably mounted therein. This is driven in rotation by a servo motor 46 also mounted within the transport arm 21. The support body 40 is mounted on the spindle 45 with a projection serving as a spindle nut 47.

Zur Übernahme einer Bobine 11a aus dem Bobinen- Vorrat 18 wird demnach zunächst der Transportarm 21 mit dem freien Transportzapfen 22 in die Bobine 11a eingefädelt. Danach wird der Transportzapfen 22 in Längsrichtung des Transportarms 21 verstellt, also aufwärts bewegt, wodurch die Bobine aus dem Traggestell 19 herausgehoben wird und damit freikommt. Sodann wird der Transportarm 21 durch entsprechenden Antrieb des Ritzels 27 auf die Schwenkebene vor der Ebene der Arbeitszapfen 13, 14 verstellt und der Transportzapfen 22 auf die axial gleichgerichtete Stellung des zu beschickenden Arbeitszapfens 13, 14 ausgerichtet. Danach erfolgt die beschriebene Schwenkbewegung des Transportarms 21. Die Einstellbewegung des Transportzapfens 22 kann auch nach der Schwenkbewegung des Transportarms 21 erfolgen.To take over a bobbin 11a from the bobbin stock 18, the transport arm 21 is therefore first threaded into the bobbin 11a with the free transport pin 22. The transport pin 22 is then adjusted in the longitudinal direction of the transport arm 21, that is to say moved upwards, as a result of which the bobbin is lifted out of the support frame 19 and is thus released. Then the transport arm 21 is adjusted by appropriate drive of the pinion 27 to the pivoting plane in front of the plane of the working pins 13, 14 and the transport pin 22 is aligned with the axially aligned position of the working pin 13, 14 to be loaded. Then the described pivoting movement of the transport arm 21 takes place. The adjusting movement of the transport pin 22 can also take place after the pivoting movement of the transport arm 21.

Das Traggestell 19 für den Bobinen-Vorrat 18 ist ebenfalls in besonderer Weise ausgebildet, nämlich derart, daß die Bobinen 11 selbsttätig und in schonender Weise ständig zum Entnahmeende gefördert werden. Zu diesem Zweck besteht das Traggestell 19 aus mehreren, im vorliegenden Fall zwei, langgestreckten, drehend angetriebenen Tragwalzen 48, 49. Diese sind in Längsrichtung des Traggestells 19 gerichtet und dienen als Trag- und Stützorgane für die Bobinen 11, 11a. In Richtung zur Entnahmeseite sind die Tragwalzen 48, 49 geringfügig divergierend gerichtet, unter einem sehr spitzen Winkel. Durch (gleichgerichteten) Drehantrieb der Tragwalzen 48, 49 wird bewirkt, daß die an der Rückseite aufgegebenen Bobinen 11, 11a stets in Richtung auf den Endanschlag 39 bis zur Dichtlage aneinander gefördert werden. Die Tragwalzen 48, 49 werden zu diesem Zweck durch einen Motor 50 angetrieben. Die zugekehrten Enden der Tragwalzen 48, 49 sind durch einen Hülltrieb, insbesondere durch einen Zahnriemen 51, getrieblich miteinander verbunden.The support frame 19 for the reel stock 18 is also designed in a special way, namely in such a way that the reels 11 are automatically and gently conveyed to the end of removal in a gentle manner. For this purpose, the support frame 19 consists of several, in the present case two, elongated, rotatably driven support rollers 48, 49. These are directed in the longitudinal direction of the support frame 19 and serve as support and support members for the bobbins 11, 11a. In the direction of the removal side, the support rollers 48, 49 slightly diverging, at a very acute angle. The (rectified) rotary drive of the support rollers 48, 49 has the effect that the bobbins 11, 11a placed on the back are always conveyed towards one another in the direction of the end stop 39 up to the sealing position. The support rollers 48, 49 are driven by a motor 50 for this purpose. The facing ends of the support rollers 48, 49 are connected to one another in a geared manner by an enveloping drive, in particular by a toothed belt 51.

Da die Bobinen 11, 11a im Bereich des Bobinen-Vorrats 18 durch die Tragwalzen 48, 49 ständig langsam drehend bewegt werden, sind zur Vermeidung von mechanischen Beanspruchungen der freien Vorderseite der Bobine 11a am Endanschlag 39 des Traggestells 19 nach innen vorspringende Stützrollen 52, 53 angebracht. Diese sind mit schräggestellten Achsen gelagert, so daß sie reibungsfrei nach Maßgabe der Drehbewegung der Bobine 11a mit umlaufen und demnach Schleifspuren etc. an dem Verpackungsmaterial vermeiden.Since the bobbins 11, 11a are continuously and slowly rotated in the area of the bobbin supply 18 by the support rollers 48, 49, support rollers 52, 53 projecting inwards at the end stop 39 of the support frame 19 to avoid mechanical stresses on the free front side of the bobbin 11a appropriate. These are mounted with inclined axes, so that they rotate smoothly in accordance with the rotational movement of the bobbin 11a and thus avoid grinding marks etc. on the packaging material.
