These reels 10 can be wrapped sheets of packaging material, e.g. B. tin foil act (Fig. 3). 3 consists of a double wide web. 1 shows bobbins 10 which are relatively narrow and, for example, from cigarette paper consist.

Die Bobinen 10 weisen einen zentralen, mittigen Bobinenkern 11 auf. Dieser kann aus einem Zellstoffmaterial bestehen. Bei den vorliegenden Ausführungsbeispielen sind jedoch die Bobinenkerne 11 aus einem festen, starren Material gebildet, z. B. aus Kunststoff.The bobbins 10 have a central, central bobbin core 11 on. This can consist of a cellulose material. Both However, the present exemplary embodiments are the bobbin cores 11 formed from a rigid, rigid material, e.g. B. from Plastic.

Der zylindrische Bobinenkern 11 trägt auf seiner äußeren Mantelfläche 12 die gewickelte Materialbahn. Eine (zylindrische) Innenfläche 13 ist mit Vorsprüngen und/oder Vertiefungen versehen. Bei dem Ausführungsbeispiel gemäß Fig. 3 und Fig. 4 ist im unteren Bereich des Bobinenkerns 11 bzw. einem Ende desselben benachbart eine ringsherum laufende Nut 14 gebildet, die zum (formschlüssigen) Ansetzen von Greif- bzw. Halteorganen dient. Die Nut 14 ist hier im Querschnitt trapezförmig ausgebildet mit ringsherum laufenden, oberen und unteren Schrägflächen 15 und 16. An einem bei entsprechender Lagerung der Bobine 10 oberen Rand des Bobinenkerns 11 ist eine konische, trichterförmige Endfläche 17 gebildet, die das Einführen von Halteorganen in den Bobinenkern 11 erleichtert. Auf der gegenüberliegenden Seite ist eine korrespondierende Gegenfläche 18 als Randbegrenzung des Bobinenkerns 11 gebildet. Die Gegenfläche 18 ist Teil eines Vorsprungs des Bobinenkerns 11, der über den Bereich der gewickelten Bahn hinwegragt und beim Stapeln von übereinander angeordneten Bobinen 10 eine selbsttätige Zentrierung der benachbarten Bobinen 10 im Bereich der Bobinenkerne 11 bewirkt.The cylindrical bobbin core 11 carries on its outer surface 12 the wound material web. A (cylindrical) Inner surface 13 is provided with projections and / or depressions. 3 and FIG. 4 is in the lower region of the bobbin core 11 or one end of the same adjacent a circumferential groove 14 formed to (positive) attachment of gripping or holding members. The groove 14 is trapezoidal in cross section all around, upper and lower inclined surfaces 15 and 16. At a top 10 with appropriate storage of the bobbin The edge of the bobbin core 11 is a conical, funnel-shaped End surface 17 formed which the insertion of holding members in the bobbin core 11 relieved. On the opposite Side is a corresponding counter surface 18 as a boundary of the bobbin core 11 is formed. The counter surface 18 is part a projection of the bobbin core 11 which extends over the area of the coiled web protrudes and when stacked one above the other arranged bobbins 10 an automatic centering of the neighboring Bobs 10 in the area of the bobbin cores 11.

Zum Handhaben, nämlich Heben und Fördern von Bobinen 10, ist ein Handhabungsaggregat 19 vorgesehen. Dieses ist hier Teil eines verfahrbaren Förderers (nicht gezeigt), insbesondere eines Überkopf-Förderers, der an hochgelegten Schienenbahnen einer Werkshalle verfahrbar ist. Das Handhabungsaggregat 19 besteht hier aus (drei) nach oben divergierenden Teleskoparmen 60, die unten gelenkig an einer gemeinsamen Tragplatte 20 befestigt sind. An dieser wiederum ist (mittelbar) ein nach unten gerichteter Tragzapfen 21 angebracht zum Erfassen einzelner oder mehrerer Bobinen 10. Das Handhabungsaggregat 19 ist vorzugsweise in der in US 5 562 393 beschriebenen Weise ausgebildet.For handling, namely lifting and conveying bobbins 10 a handling unit 19 is provided. This is part here a movable conveyor (not shown), in particular an overhead conveyor on elevated railways a factory hall can be moved. The handling unit 19 exists here from (three) upward diverging telescopic arms 60, which is hinged at the bottom to a common support plate 20 are. At this in turn is (indirectly) a down Directed trunnion 21 attached to capture individual or several bobbins 10. The handling unit 19 is preferred formed in the manner described in US 5,562,393.

Der Tragzapfen 21 wird zum Erfassen einer Bobine 10 (oder mehrerer übereinanderliegender Bobinen 10) in eine durch den Bobinenkern 11 gebildete mittige Öffnung 22 eingeführt. Der im wesentlichen zylindrische Tragzapfen 21 ist so bemessen, daß der Außendurchmesser geringfügig kleiner ist als der Innendurchmesser der Öffnung 22.The trunnion 21 is used to grip a bobbin 10 (or more overlying bobbins 10) into one through the bobbin core 11 formed central opening 22 inserted. The essentially cylindrical support pin 21 is dimensioned so that the Outside diameter is slightly smaller than the inside diameter the opening 22.

Innerhalb der Öffnung 22 bzw. innerhalb des Bobinenkerns 11 wird der Tragzapfen 21 lösbar verankert, derart, daß die Bobine 10 durch den Tragzapfen 21 angehoben werden kann. Zu diesem Zweck sind seitlich, also in queraxialer Richtung des Tragzapfens 21, Halteorgane ausfahrbar, die eine kraft- und/oder formschlüssige Verbindung mit dem Bobinenkern 11 eingehen.Within the opening 22 or within the bobbin core 11 the support pin 21 is releasably anchored such that the bobbin 10 can be raised by the support pin 21. To this Purpose are laterally, that is in the transverse axial direction of the trunnion 21, holding members extendable, which is a non-positive and / or positive Make connection with the bobbin core 11.

Bei dem vorliegenden Ausführungsbeispiel sind längs des Umfangs des Tragzapfens 21 mehrere (drei) langgestreckte Spannorgane, nämlich Spannstege 23 vorgesehen. Die Spannstege 23 sind Teil eines den Tragzapfen 21 bildenden zylindrischen, rohrförmigen Zapfenkörpers 24. Die Spannstege 23 sitzen jeweils mit geringem Spiel in aufrechten, in Längsrichtung des Tragzapfens 21 verlaufenden Schlitzen 25.In the present embodiment, are along the circumference of the trunnion 21 several (three) elongated tensioning elements, namely tensioning webs 23 are provided. The tie bars 23 are part one of the supporting pin 21 forming cylindrical, tubular Pin body 24. The tensioning webs 23 each sit with a slight Play in an upright, extending in the longitudinal direction of the trunnion 21 Slits 25.

Die langgestreckten Spannstege 23 werden zum Erfassen einer Bobine 10 queraxial ausgefahren, so daß sie über die Mantelfläche des Zapfenkörpers 24 hinwegragen. Dadurch kommt der Spannsteg 23 in einem (oberen) Bereich unter Kraftschluß zur Anlage an der Innenfläche 13 des Bobinenkerns 11. Zusätzlich ist eine formschlüssige Verbindung zwischen Spannsteg 23 und Bobinenkern 11 vorgesehen. Seitwärts gerichtete Vorsprünge 26 der Spannstege 23 treten formschlüssig in die Nut 14 ein, im vorliegenden Fall unter Anlage an der oberen Schrägfläche 15. Die Vorsprünge 26 sind an den unteren Enden der Spannstege 23 angebracht. Zum Absetzen einer transportierten Bobine 10 werden die Spannstege 23 nach innen zurückbewegt in eine Ausgangsstellung, in der sie einschließlich der Vorsprünge 26 nicht über die Kontur des Tragzapfens 21 hinwegragen.The elongated tensioning webs 23 are used to grasp a bobbin 10 extended axially so that they over the lateral surface protrude from the pin body 24. This is where the instep comes 23 in an (upper) area with frictional connection to the system the inner surface 13 of the bobbin core 11. In addition, a positive connection between tensioning web 23 and bobbin core 11 provided. Sideways projections 26 of the tensioning webs 23 positively enter the groove 14, in the present case Fall under contact with the upper inclined surface 15. The projections 26 are attached to the lower ends of the tensioning webs 23. To set down a transported bobbin 10, the Tensioning webs 23 moved back inward into a starting position, in which they, including the protrusions 26, do not have the contour of the trunnion 21 protrude.

Die Betätigung der Spannstege 23 erfolgt aus dem Inneren des hohlen Tragzapfens 21. Jeder Spannsteg 23 ist mit mehreren Laschen 27, 28, 29 im Inneren des Tragzapfens 21 abgestützt. Die an beiden Enden jeweils gelenkig gelagerten Laschen 27, 28 und 29 bilden eine Parallelogrammverbindung, welche eine Parallelverschiebung des Spannstegs 23 nach außen oder innen bewirkt. The tensioning webs 23 are actuated from inside the hollow trunnion 21. Each tensioning web 23 has several tabs 27, 28, 29 supported in the interior of the trunnion 21. The at both ends hinged tabs 27, 28 and 29 form a parallelogram connection, which is a parallel displacement of the web 23 outwards or inwards.

Die unteren, verhältnismäßig kurzen Laschen 28, 29 sind an quergerichteten, inneren Zwischenwänden 30, 31 des Tragzapfens 21 abgestützt. Die Laschen 28 und 29 sind so bemessen und positioniert, daß beim Anheben einer Bobine 10 eine selbstklemmende Wirkung entsteht durch das Eigengewicht der Bobine 10. Wie insbesondere aus Fig. 3 ersichtlich, sind zu diesem Zweck die Laschen 28, 29 in der Tragposition unter einem sehr spitzen Winkel leicht von innen nach außen aufwärts geneigt, jedenfalls so, daß die Laschen 28, 29 nicht unter dem Eigengewicht der Bobine 10 über eine Totpunktstellung hinwegbewegt werden können.The lower, relatively short tabs 28, 29 are on transverse inner partition walls 30, 31 of the trunnion 21 supported. The tabs 28 and 29 are sized and positioned so that when lifting a bobbin 10 a self-locking Effect arises from the weight of the Bobine 10. As in particular 3, the tabs are for this purpose 28, 29 in the carrying position at a very acute angle slightly inclined from the inside outwards, at least so that the tabs 28, 29 are not under the weight of the bobbin 10 can be moved over a dead center position.

Die obere Lasche 27 dient vor allem zur Betätigung, nämlich Aus- und Einfahren des Spannstegs 23. Innerhalb des Tragzapfens 21 ist hierfür ein Betätigungsorgan vorgesehen. Zu diesem Zweck sind die (drei) Laschen 27 an einem gemeinsamen Stellorgan angeordnet, nämlich an einer Druckplatte 32. Diese befindet sich am (unteren) Ende einer Kolbenstange 33, die wiederum in Axialrichtung, also in Aufwärts- und Abwärtsrichtung, mit der Druckplatte 32 verschiebbar ist. Durch Abwärtsbewegen der Druckplatte 32 werden die (längeren) Laschen 27 in spreizendem Sinne beaufschlagt, mit der Folge, daß die Spannstege 23 nach außen bewegt werden. Durch Aufwärtsbewegung der Druckplatte 32 ergibt sich die gegenläufige Bewegung.The upper tab 27 is used primarily for actuation, namely Extending and retracting the tensioning web 23. Inside the trunnion 21 an actuator is provided for this. To this end the (three) tabs 27 are arranged on a common actuator, namely on a pressure plate 32. This is located at the (lower) end of a piston rod 33, which in turn is in the axial direction, So in the up and down direction, with the pressure plate 32 is displaceable. By moving the pressure plate down 32 become the (longer) tabs 27 in a spreading sense acted on, with the result that the tensioning webs 23 to the outside be moved. By moving the pressure plate 32 upwards the opposite movement.

Die Druckplatte 32 ist zur Durchführung einer abwärtsgerichteten Spreiz- bzw. Betätigungsbewegung durch ein Druckorgan beaufschlagbar. Bei diesem handelt es sich im vorliegenden Falle um eine (vorgespannte) spiralförmige Druckfeder 34. Diese ist auf der Kolbenstange 33 positioniert sowie unten auf der Druckplatte 32 und oben auf einem festen Stützlager 35 abgestützt. Die Kolbenstange 33 kann gleitend durch das Stützlager 35 hindurchbewegt werden, nämlich beim Zusammendrücken der Druckfeder 34.The pressure plate 32 is for performing a downward Spreading or actuating movement can be acted upon by a pressure element. This is the case here around a (prestressed) spiral compression spring 34. This is positioned on the piston rod 33 and below on the pressure plate 32 and supported on top of a fixed support bearing 35. The piston rod 33 can slide through the support bearing 35 are, namely when compressing the compression spring 34.

Die Spannstege 23 werden demnach durch die Druckfeder 34, also durch ein von äußerer Energiezufuhr, insbesondere einem Druckmedium, unabhängiges Organ in die Spreizstellung bewegt. Zur Rückholbewegung in die Ausgangsstellung dient ein (Druckmittel)Zylinder 36, insbesondere ein Pneumatikzylinder. Dieser wird mit Druckluft beaufschlagt, derart, daß die Druckplatte 32 unter Zusammendrücken der Druckfeder 34 angehoben und die Spannstege 23 dadurch in die Ausgangsstellung zurückbewegt werden.The tensioning webs 23 are accordingly by the compression spring 34, that is by an external energy supply, in particular a pressure medium, independent organ moved into the spread position. For A (pressure medium) cylinder serves to return to the starting position 36, in particular a pneumatic cylinder. This will pressurized with compressed air such that the pressure plate 32 under Compression of the compression spring 34 raised and the tensioning webs 23 thereby be moved back to the starting position.

Ein Überwachungsorgan, nämlich ein Initiator 69 ist im Bereich einer oberen Querwand 37 des Tragzapfens 21 angeordnet und ragt in einer bestimmten Relativstellung in den Tragzapfen 21, derart, daß ein Fehlersignal erzeugt wird, wenn die Druckplatte 32 zur Aufnahme einer Bobine 10 und nach dem Freigeben durch den Zylinder 36 nicht durch die Druckfeder 34 abwärtsbewegt wird, wenn also hinsichtlich der Erfassung einer Bobine 10 ein Fehler vorliegt.A monitoring body, namely an initiator 69 is in the area an upper transverse wall 37 of the support pin 21 arranged and protrudes in a certain relative position in the trunnion 21, such that an error signal is generated when the printing plate 32nd to take a bobbin 10 and after the release by the Cylinder 36 is not moved downward by compression spring 34, if there is a mistake in the detection of a bobbin 10 is present.

Die Bewegung des Tragzapfens 21 ist selbsttätig steuerbar, derart, daß der Tragzapfen 21 zur Aufnahme einer Bobine 10 exakt auf die Öffnung 22 ausgerichtet wird. Zu diesem Zweck ist im unteren Bereich des Tragzapfens 21, nämlich in einer durch die Zwischenwand 30 abgeteilten unteren Kammer eine Steuereinheit untergebracht. Diese arbeitet mit einer Kamera 38, deren Objektiv 39 unten bzw. am Ende im Tragzapfen 21 positioniert ist. Bei dem vorliegenden Ausführungsbeispiel sitzt das Objektiv 39 in einer nach unten offenen Vertiefung 40 des Tragzapfens 21.The movement of the trunnion 21 can be controlled automatically, such that that the support pin 21 for receiving a bobbin 10 exactly is aligned with the opening 22. For this purpose, lower region of the trunnion 21, namely in a through the Partition 30 partitioned lower chamber a control unit housed. This works with a camera 38, the lens 39 is positioned below or at the end in the support pin 21. In the present exemplary embodiment, the lens 39 is seated in a downwardly open recess 40 of the trunnion 21.

Die Kamera 38 erfaßt bei der Arbeitsbewegung des Handhabungsaggregats 19 die Position der aufzunehmenden Bobine 10. Zweckmäßigerweise wird die Kamera 38 dabei auf das Bild des Bobinenkerns 11 ausgerichtet. Dieser kann zu diesem Zweck farblich abgesetzt sein. Die von der Kamera 38 aufgenommenen Bilder werden über eine elektronische Einheit 41 verarbeitet und über eine elektrische Leitung 42 einer zentralen Auswerteeinheit zugeführt, außerhalb des Tragzapfens 21. Die Leitung 22 ist über einen Stecker 43 mit der elektronischen Einheit 41 verbunden.The camera 38 captures the working movement of the handling unit 19 the position of the bobbin to be picked up 10. Conveniently the camera 38 is thereby on the image of the bobbin core 11 aligned. This can be colored for this purpose be deposed. The images captured by the camera 38 become processed via an electronic unit 41 and via an electrical line 42 is fed to a central evaluation unit, outside the trunnion 21. The line 22 is over a plug 43 connected to the electronic unit 41.

Der Vorrichtung bzw. dem Tragzapfen 21 ist eine Mehrzahl von Sicherungsorganen zugeordnet, die fehlerhafte Handhabungen ausschließen. Insbesondere geht es um die Berücksichtigung von etwaigen Fehlstellungen des Tragzapfens 21 relativ zur Bobine 10.The device or the support pin 21 is a plurality of Security agencies assigned to improper handling exclude. In particular, it is about taking into account any misalignment of the trunnion 21 relative to the bobbin 10th

Am freien bzw. unteren Ende des Tragzapfens 21 ist ein mechanisches Tastorgan angeordnet, welches bei einer zur Öffnung 22 versetzten Position des Tragzapfens 21 ein Fehlersignal auslöst. Das Tastorgan ist ein Prallkörper 44, der gegen elastischen Druck relativ zum Tragzapfen 21 in dessen Axialrichtung, also in den Tragzapfen 21 hinein, verschiebbar ist. Der Prallkörper 44 ist ring- bzw. zylinderförmig ausgebildet und umgibt die Vertiefung 40. Über Stützfedern 45 ist der Prallkörper 44 am Gehäuse des Tragzapfens 21 abgestützt, und zwar an der unteren Zwischenwand 31. Zur Führung des Prallkörpers 44 dienen mehrere, nämlich drei Führungsstangen 46, 47, die längs des Umfangs des Prallkörpers 44 verteilt sind. Die Stützfedern 45 sitzen auf den Führungsstangen 46, 47. Diese können in entsprechenden Ausnehmungen des Prallkörpers 44 gleiten, so daß dieser unter Zusammendrücken der Stützfedern 45 in die Vertiefung 40 hineinverschoben werden kann, wenn das freie Ende bzw. der freie Rand des Prallkörpers 44 belastet wird.At the free or lower end of the trunnion 21 there is a mechanical one Probe arranged, which at an opening 22nd offset position of the trunnion 21 triggers an error signal. The feeler element is an impact body 44, which resists elastic Pressure relative to the trunnion 21 in its axial direction, thus into the support pin 21, is displaceable. The impact body 44 is ring-shaped or cylindrical and surrounds the depression 40. The impact body 44 is above support springs 45 supported on the housing of the trunnion 21, namely on the lower Partition 31 serve to guide the impact body 44 several, namely three guide rods 46, 47, which run along the circumference of the impact body 44 are distributed. The support springs 45 sit on the guide rods 46, 47. These can be in corresponding Recesses of the impact body 44 slide so that it by compressing the support springs 45 into the recess 40 can be moved if the free end or the free edge of the impact body 44 is loaded.

In der Ausgangsstellung ragt der Prallkörper 44 über den Tragzapfen 21 hinaus. Ein Absatz 48 des Prallkörpers 44 liegt dabei an einem Anschlag 49 des Tragzapfens 21 an.In the starting position, the impact body 44 protrudes over the support pin 21 beyond. A shoulder 48 of the impact body 44 is located on a stop 49 of the support pin 21.

Zum Erzeugen eines Fehlersignals ist die Führungsstange 46 nach oben in das Innere des Tragzapfens 21 als Betätigungsorgan verlängert. Die Führungsstange 46 erstreckt sich bis an die Zwischenwand 30. An der Unterseite derselben ist ein berührungsloses Tastorgan angeordnet, nämlich ein Initiator 50. Eine Verdickung der Führungsstange 47 arbeitet mit dem Schaltorgan bzw. Initiator 50 zusammen, derart, daß bei einer Aufwärtsbewegung in die Stellung gemäß Fig. 3 bzw. gemäß Fig. 5 ein Schaltsignal erzeugt wird.To generate an error signal, the guide rod 46 is behind Extended into the interior of the trunnion 21 as an actuator. The guide rod 46 extends to the intermediate wall 30. At the bottom of the same is a non-contact Arranged probe, namely an initiator 50. A thickening the guide rod 47 works with the switching element or Initiator 50 together, such that when moving upward in the position shown in FIG. 3 or in FIG. 5, a switching signal is produced.

Der Tragzapfen 21 ist insgesamt bewegbar am Handhabungsaggregat 19 gelagert. Die topfartig ausgebildete obere Querwand 31 als Teil des Tragzapfens 21 ist bewegbar am Handhabungsaggregat 19 gelagert, nämlich an der Tragplatte 20. Der Tragzapfen 21 bzw. die Querwand 37 kann durch die gewählte Verbindung eine Schrägstellung zum Handhabungsaggregat 19 bzw. zur Tragplatte 20 einnehmen. Dadurch wird ein Fehlersignal erzeugt.The support pin 21 is movable overall on the handling unit 19 stored. The pot-shaped upper transverse wall 31 as Part of the trunnion 21 is movable on the handling unit 19 stored, namely on the support plate 20. The support pin 21 or the transverse wall 37 can be inclined by the selected connection to the handling unit 19 or to the support plate 20. This generates an error signal.

Bei dem vorliegenden Beispiel ist zu diesem Zweck die Querwand 37 über Tragbolzen 51 mit der Tragplatte 20 verbunden. Die Tragbolzen 51 sind unten fest mit der Querwand 37 verbunden, am gegenüberliegenden Ende aber in Längsrichtung verschiebbar in entsprechenden Bohrungen 52 der Tragplatte 20 gelagert. Der Tragzapfen 21 kann dadurch - mit der Querwand 37 - relativ zur Tragplatte 20 angehoben werden, wobei die Tragbolzen 51 nach oben hin in den Bohrungen 52 verschoben werden. Die in Fig. 3 gezeigte Normal stellung ist durch Druckfedern 53 gesichert, die sich auf der Querwand 37 einerseits und der Tragplatte 20 andererseits abstützen. Eine Verschiebung des Tragzapfens 21 relativ zur Halterung bzw. Tragplatte 20 führt zur Betätigung eines Schaltorgans, nämlich eines Initiators 54, der mit einer an einem der Tragbolzen 51 angeordneten Schaltfahne 55 zusammenwirkt.In the present example, the transverse wall is for this purpose 37 connected to the support plate 20 via support bolts 51. The Support bolts 51 are firmly connected to the transverse wall 37 at the bottom opposite end but slidable in the longitudinal direction corresponding bores 52 of the support plate 20 stored. Of the Trunnion 21 can thereby - with the transverse wall 37 - relative to Support plate 20 are raised, the support bolts 51 after be moved upwards in the bores 52. 3 shown normal position is secured by compression springs 53, the on the transverse wall 37 on the one hand and the support plate 20 on the other support. A displacement of the trunnion 21 relative to the bracket or support plate 20 leads to the actuation of a Switching device, namely an initiator 54, the one with one of the support bolts 51 arranged switching lug 55 cooperates.

Die Relativbewegung ist begrenzt durch eine Abdeckung 56 auf der Oberseite der Querwand 37. Auf der Abdeckung 56 ist ein Distanzring 57 angebracht, dessen Öffnung größer ist als der Außenumfang der Tragplatte 20, so daß diese in den Distanzring 57 eintauchen kann, wenn der Tragzapfen 21 fehlerhaft aufgesetzt wird.The relative movement is limited by a cover 56 the top of the transverse wall 37. On the cover 56 is a Spacer ring 57 attached, the opening of which is larger than that Outer periphery of the support plate 20 so that it is in the spacer ring 57 can dip if the trunnion 21 is placed incorrectly becomes.

Der Tragzapfen 21 ist so ausgelegt, daß bei entsprechenden Abmessungen auch mehrere Bobinen 10 gleichzeitig aufgenommen werden können (Fig. 1). Der Tragzapfen 21 tritt in die durch die übereinander anliegenden und zentrierten Bobinen 10 gebildete gemeinsame Öffnung 22 ein. Bei dem vorliegenden Ausführungsbei spiel sind die Abmessungen so gegeben, daß im Bereich einer unteren Bobine 10 des Bobinenstapels die Vorsprünge 26 der Spannstege 23 in eine in der beschriebenen Weise ausgebildeten Nut 14 eintreten. Von der Mehrzahl der Bobinen 10 wird demnach lediglich die untere formschlüssig erfaßt, während die darüberliegenden kraftschlüssig durch die Spannstege 23 gehalten sind.The support pin 21 is designed so that with appropriate dimensions also several bobbins 10 can be recorded simultaneously can (Fig. 1). The trunnion 21 enters through the overlapping and centered bobbins 10 formed common opening 22 a. In the present embodiment game dimensions are given so that in the area of a lower reel 10 of the reel stack the projections 26 of the Tie bars 23 in a manner as described Enter groove 14. The majority of the bobbins 10 accordingly only the lower positively grasped, while the ones above are held non-positively by the tensioning webs 23.

Das Handhabungsaggregat 19 ist als weitere Besonderheit mit einer (zusätzlichen) Sicherung versehen, um ein unerwünschtes Herabfallen der Bobinen 10 vom Tragzapfen 19 zu vermeiden. Zu diesem Zweck ist ein bewegliches Stützorgan vorgesehen, welches mit dem Handhabungsaggregat 19 verbunden ist und welches nach Aufnahme einer oder mehrerer Bobinen 10 durch einen Tragzapfen 21 gegen die Unterseite der Bobinen 10 bzw. gegen das freie Ende des Tragzapfens 21 bewegbar ist. The handling unit 19 is another special feature an (additional) fuse to prevent unwanted To avoid falling of the bobbins 10 from the trunnion 19. To for this purpose, a movable support member is provided, which is connected to the handling unit 19 and which after Picking up one or more bobbins 10 by a trunnion 21 against the underside of the reels 10 or against the free End of the trunnion 21 is movable.

Bei dem Ausführungsbeispiel gemäß Fig. 1 ist ein Stützschenkel 58 vorgesehen, der über einen Schwenkarm 59 mit dem Handhabungsaggregat 19 verbunden ist, nämlich mit einem Teleskopteil 60. Seitlich am Teleskopteil 60 eine Halterung 61 angebracht. An dieser ist der Schwenkarm 59 in einem Schwenklager 62 gelagert. Zur Durchführung von Schwenkbewegungen dient ein Motor 63 mit Getriebe 64.1 is a support leg 58 provided, via a swivel arm 59 with the handling unit 19 is connected, namely with a telescopic part 60. A bracket 61 is attached to the side of the telescopic part 60. The swivel arm 59 is mounted on this in a swivel bearing 62. A motor 63 is used to perform swiveling movements with gear 64.

Zur Stützung bzw. Sicherung der Bobinen 10 auf dem Tragzapfen 21 wird das Halteorgan, nämlich der Stützschenkel 58 aus einer oberen Ausgangsstellung durch den Schwenkarm 59 in die in Fig. 1 gezeigte Stellung unterhalb der Bobinen 10 bzw. des Tragzapfens 21 geschwenkt. Wenn sich die Bobinen 10 unerwünschterweise auf dem Tragzapfen 21 abwärtsbewegen, wird ein Herunterfallen durch den Stützschenkel 58 vermieden.To support or secure the bobbins 10 on the trunnion 21 is the holding member, namely the support leg 58 from a upper starting position by the swivel arm 59 in the in Fig. 1 position shown below the bobbin 10 and the Trunnion 21 pivoted.
