Abstract

Supplying packaging material in web form to high-output packaging machines has hitherto been labour-intensive. The packaging material must be fed in the form of reels (13) to the packaging machine and conveyed in the region thereof to a working spindle (11, 12). For this, manual intervention was hitherto required. …<??>For the fully mechanical transfer of reels (13) from a reel stock (15) to one of two working spindles (11, 12), use is made of a transport spindle (20) mounted on a transport arm (21). The reels (13) are transferred from said spindle (20) to a working spindle (11, 12) by axially parallel displacement of a driver, namely a pushing sleeve (44) actuated by the transport arm. Furthermore, the transport arm (21) and sleeve strippers (51, 52) mounted thereon are used to strip a reel core (14) of a completely unwound reel (13a) from the working spindle (11, 12). …<??>The reels (13) of the packaging material are in this case supplied to the packaging machine completely automatically with the exclusion of manual intervention. …<IMAGE>…

Description

Die Erfindung betrifft eine Verpackungsmaschine zum Herstellen von (Zigaretten-)Verpackungen aus bahnförmigem Verpackungsmate­rial, welches von einer (Arbeits-)Bobine auf einem Arbeitszap­fen abgezogen wird, wobei neue, "volle" Bobinen durch einen Transportzapfen in axialer Ausrichtung vor den Arbeitszapfen gefördert und durch axiales Verschieben auf diesen übertragen werden.The invention relates to a packaging machine for producing (cigarette) packaging from sheet-like packaging material which is pulled off a (working) bobbin on a working spigot, new, "full" bobbins being conveyed by a transport spigot in axial alignment in front of the working spigot and by axial displacement can be transferred to this.

Bei einer derartigen Verpackungsmaschine werden üblicherweise die Bobinen aus Verpackungsmaterial einem maschinenseitigen Bobinenvorrat entnommen und sodann dem Arbeitszapfen mit einer leergefahrenen Bobine zugestellt. Der Transportzapfen kann auf dem Wege zum Bobinenvorrat bzw. von diesem zum Arbeitszapfen unterschiedliche Bewegungsbahnen zurücklegen. Bei einer Verpak­ kungsmaschine gemäß älterer Patentanmeldung P 37 21 091.2 ist der Transportzapfen an einem Transportarm angeordnet. Dieser ist zwischen dem Bobinenvorrat einerseits und einem von zwei Arbeitszapfen durch Verschwenken hin- und herbe­wegbar. Der Arbeitszapfen ist zur exakten Einstellung auf die Bobinen bzw. die Arbeitszapfen in Längsrichtung des Transportarms an diesem verschiebbar.In such a packaging machine, the bobbins are usually taken from packaging material from a machine-side bobbin supply and then delivered to the working pin with an empty bobbin. The transport pin can cover different trajectories on the way to the reel supply or from this to the work pin. With a package kungsmaschine according to older patent application P 37 21 091.2, the transport pin is arranged on a transport arm. This can be moved back and forth between the bobbin supply on the one hand and one of two working pins by swiveling. The working pin can be moved on the bobbin or the working pin in the longitudinal direction of the transport arm for exact adjustment.

Bei bekannten Vorrichtungen bzw. Verpackungsmaschinen ebenso wie beim Gegenstand der älteren Patentanmeldung sind manuelle Eingriffe erforderlich, um die Übergabe der (vollen) Bobinen auf den jeweiligen Arbeitszapfen zu er­möglichen.In known devices or packaging machines as well as in the subject of the earlier patent application, manual interventions are required to enable the (full) bobbins to be transferred to the respective working spigot.

Der Erfindung liegt demgemäß die Aufgabe zugrunde, den Wechsel der Bobinen aus Verpackungsmaterial innerhalb ei­ner Verpackungsmaschine weiter zu mechanisieren und von manuellen Eingriffen vollständig zu befreien.The object of the invention is accordingly to further mechanize the change of the bobbins from packaging material within a packaging machine and to completely free it from manual interventions.

Zur Lösung dieser Aufgabe ist die erfindungsgemäße Verpak­kungsmaschine dadurch gekennzeichnet, daß die Bobine durch mechanische Fördermittel vom Transportzapfen auf den Ar­beitszapfen überführbar ist.To achieve this object, the packaging machine according to the invention is characterized in that the bobbin can be transferred from the transport pin to the working pin by mechanical conveying means.

Die Übergabe der Bobinen vom Transportzapfen auf den gleichachsig gerichteten Arbeitszapfen ist durch die Er­findung von manuellen Eingriffen befreit.The handover of the bobbins from the transport spigot to the coaxially oriented working spigot is freed from manual intervention by the invention.

Das mechanische Fördermittel zur Übergabe der Bobine vom Transportzapfen an den Arbeitszapfen ist erfindungsgemäß ein in Axialrichtung bewegbarer Abstreifer, insbesondere eine Schubhülse, die durch achsparallele Bewegung die Bo­bine vom Tranportzapfen auf den unmittelbar an das freie Ende des Transportzapfens anschließenden Arbeitszapfen schiebt.According to the invention, the mechanical conveying means for transferring the bobbin from the transport spigot to the working spigot is a scraper which can be moved in the axial direction, in particular a thrust sleeve which, by means of axially parallel movement, pushes the bobbin from the transport spigot onto the working spigot directly adjoining the free end of the transport spigot.

Die Förderbewegung des Schiebers bzw. der Schubhülse wird erfindungsgemäß durch den Transportarm bewirkt. Dieser ist demnach in der Übergabeposition für eine Bobine in achspa­ralleler Richtung bewegbar.The conveying movement of the slide or the push sleeve is effected according to the invention by the transport arm. Accordingly, this can be moved in the transfer position for a bobbin in the axis-parallel direction.

Bei einer bevorzugten Ausführungsform der Erfindung wird in der Übergabeposition der Transportzapfen vor das freie Ende des aufnahmebereiten Arbeitszapfens gefahren und auf diesem abgestützt. Sodann wird der Transportarm in Axial­richtung verfahren unter Mitnahme des Schiebers bzw. der Schieberhülse. Diese wird relativ zum Transportzapfen be­wegt unter Mitnahme der Bobine, bis diese auf dem Arbeits­zapfen sitzt.In a preferred embodiment of the invention, in the transfer position the transport pin is moved in front of the free end of the working pin which is ready to receive and is supported on the latter. The transport arm is then moved in the axial direction, taking the slide or the slide sleeve with it. This is moved relative to the transport spigot, taking the bobbin with it until it sits on the working spigot.

Gemäß einem weiteren Vorschlag der Erfindung wird auch ein Bobinenkern einer leergefahrenen Bobine selbsttätig und mechanisch von dem betrefffenden Arbeitszapfen entfernt, bevor die nächste (volle) Bobine auf den Arbeitszapfen ge­schoben wird. Zu diesem Zweck ist erfindungsgemäß ein För­derorgan vorgesehen, welches den Bobinenkern erfaßt und durch entsprechende Förderbewegung in Längsrichtung des Arbeitszapfens mitnimmt. Vorzugsweise ist dieses Förderor­gan als Abstreifer ausgebildet, der den Bobinenkern an ei­ner innenliegenden Stirnfläche erfaßt und und vom Arbeits­zapfen abstreift.According to a further proposal of the invention, a bobbin core of an empty bobbin is automatically and mechanically removed from the working pin in question before the next (full) bobbin is pushed onto the working pin. For this purpose, a conveyor element is provided according to the invention, which grasps the bobbin core and takes it along with the corresponding conveyor movement in the longitudinal direction of the working pin. This conveyor element is preferably designed as a scraper, which grasps the bobbin core on an inner end face and wipes it off the working pin.

Der vorgenannte Abstreifer ist erfindungsgemäß mit dem Transportarm des Transportzapfens verbunden und wird durch diesen in geeigneter Weise betätigt.According to the invention, the abovementioned scraper is connected to the transport arm of the transport pin and is actuated by this in a suitable manner.

So wird ein vollständig mechanisiertes Auswechseln der Bo­binen innerhalb einer Verpackungsmaschine ohne manuelle Eingriffe ermöglicht.This enables a fully mechanized replacement of the bobbins within a packaging machine without manual intervention.

Weitere Merkmale der Erfindung betreffen die Ausgestaltung der Förderorgane für Bobinen und Bobinenhülsen.Further features of the invention relate to the design of the conveying members for bobbins and bobbin tubes.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend an­ hand der Zeichnungen näher erläutert. Es zeigt:

Die in den Zeichnungen als Ausführungsbeispiel dargestell­te Bobinenstation entspricht in ihrem Grundaufbau der Vor­richtung gemäß DE-Patentanmeldung P 37 21 091.2. Demnach sind an einem Maschinengestell 10 einer herkömmlichen und der Einfachheit halber nicht näher gezeigten Verpackungs­maschine zwei Arbeitszapfen 11 und 12 drehbar gelagert. Die frei abstehenden bzw. auskragenden Arbeitszapfen 11, 12 dienen je zur Aufnahme einer Bobine 13.The basic structure of the reel station shown in the drawings as an embodiment corresponds to the device according to DE patent application P 37 21 091.2. Accordingly, two working pins 11 and 12 are rotatably mounted on a machine frame 10 of a conventional packaging machine which is not shown for the sake of simplicity. The freely projecting or projecting working pins 11, 12 each serve to receive a bobbin 13.

Die Bobinen 13 sind gewickelte Rollen bahnförmigen Verpak­kungsmaterials, zum Beispiel Stanniol, Kunststoff-Folie oder dgl. Für die Verarbeitung des Verpackungsmaterials innerhalb der Verpackungsmaschine wird das bahnförmige Verpackungsmaterial von einer laufenden (Arbeits-)Bobine 13a abgezogen. Ist diese verbraucht, wird das Verpackungs­material von einer auf dem benachbarten Arbeitszapfen 11 bereitgehaltenen, "vollen" Bobine 13 abgezogen.The bobbins 13 are wound rolls of sheet-like packaging material, for example tin foil, plastic film or the like. For the processing of the packaging material within the packaging machine, the sheet-like packaging material is drawn off from a running (working) bobbin 13a. When this has been used up, the packaging material is drawn off from a "full" bobbin 13 held on the adjacent working pin 11.

Währenddessen wird der leergefahrene Arbeitszapfen 12 für die Aufnahme einer neuen, "vollen" Bobine vorbereitet. Zu diesem Zweck wird zunächst ein hülsenförmiger Bobinenkern 14 beseitigt. Danach wird eine neue Bobine auf den Ar­beitszapfen 12 aufgeschoben.In the meantime, the empty working pin 12 is being prepared for receiving a new, "full" bobbin. For this purpose, a sleeve-shaped bobbin core 14 is first removed. Then a new bobbin is pushed onto the work pin 12.

Die "vollen" Bobinen 13 werden einem Bobinenvorrat 15 entnommen und alternativ dem einen oder anderen Arbeits­zapfen 11, 12 zugeführt. Im Bereich des Bobinenvorrats 15 ist eine Mehrzahl von Bobinen 13 in aufrechter Ebene und in axialer Ausrichtung zueinander angeordnet. Die jeweils vornliegende Bobine 13 wird entnommen. Die nachfolgenden werden entsprechend weitergefördert. Wie bei der Vorrich­tung gemäß Patentanmeldung P 37 21 091.2 liegen die Bobi­nen 13 des Bobinenvorrats 15 auf fördernd angetriebenen Tragwellen 16, 17 auf. Die jeweils vornliegende Bobine 13 erhält Anlage an Stützrollen 18 mit schräggerichteter Drehachse. Tragwellen 16, 17 sowie Stützrollen 18 sind an einem Traggestell 19 gelagert.The "full" bobbins 13 are taken from a bobbin stock 15 and alternatively fed to one or the other working pin 11, 12. In the area of the bobbin supply 15, a plurality of bobbins 13 are arranged in an upright plane and in axial alignment with one another. The front bobbin 13 is removed. The following are promoted accordingly. As with the device according to patent application P 37 21 091.2, the bobbins 13 of the bobbin supply 15 rest on supporting shafts 16, 17 which are driven in a conveying manner. The respective front bobbin 13 receives support on support rollers 18 with an inclined axis of rotation. Support shafts 16, 17 and support rollers 18 are mounted on a support frame 19.

Der mechanisierte bzw. automatisierte Transport der Bobi­nen 13 zu den Arbeitszapfen 11, 12 wird durch einen Trans­portzapfen 20 bewerkstelligt. Dieser nimmt jeweils die vordere Bobine 13 im Bobinenvorrat auf, vollzieht eine Hubbewegung, damit die Bobine freikommt, bewegt sie sodann in eine Ebene vor den Arbeitszapfen 11, 12 und stellt sie daraufhin einem der beiden zu.The mechanized or automated transport of the bobbins 13 to the work pins 11, 12 is accomplished by a transport pin 20. This takes up the front bobbin 13 in the bobbin supply, executes a lifting movement so that the bobbin is released, then moves it into a plane in front of the working pins 11, 12 and then delivers it to one of the two.

Der Transportzapfen 20 ist zu diesem Zweck an einem Förde­rer angebracht, der hier als schwenkbarer Transportarm 21 ausgebildet ist, und zwar im wesentlichen mit den Merkma­len der Patentanmeldung P 37 21 091.2.For this purpose, the transport pin 20 is attached to a conveyor, which is designed here as a pivotable transport arm 21, essentially with the features of the patent application P 37 21 091.2.

Der Transportarm 21 ist mit einem unteren Endbereich mit einem Schwenklager 22 an einer Tragvorrichtung 23 ange­bracht. Diese ist in Seitenansicht (Fig. 3) U-förmig aus­gebildet mit aufrechten Tragwandungen 24, 25 an den Enden.The transport arm 21 is attached to a support device 23 with a lower end region with a pivot bearing 22. This is U-shaped in side view (Fig. 3) with upright support walls 24, 25 at the ends.

In diesen ist eine verzahnte Hauptwelle 26 drehbar gela­gert. Der Antrieb derselben erfolgt über einen Antriebsmo­tor 27 mit Ritzel 28, Zwischenzahnrad 29 und Zahnrad 30, welches Teil einer drehbar gelagerten Führungshülse 31 ist. In dieser ist die Hauptwelle 26 relativ unverdrehbar, jedoch axial verschiebbar gelagert. Der hin- und hergehen­de Drehantrieb für den Transportarm 21 wird demnach über die Führungshülse 31 auf die mit dem Transportarm 21 ver­bundene Hauptwelle 26 übertragen.A toothed main shaft 26 is rotatably mounted in these. They are driven by a drive motor 27 with pinion 28, intermediate gear 29 and gear 30, which is part of a rotatably mounted guide sleeve 31. In this, the main shaft 26 is relatively non-rotatable, but axially displaceably. The reciprocating rotary drive for the transport arm 21 is accordingly transmitted via the guide sleeve 31 to the main shaft 26 connected to the transport arm 21.

Die Tragvorrichtung 23 ist insgesamt in Richtung quer zur Schwenkebene des Transportarms 21 hin- und herbewegbar. Zu diesem Zweck ist an der Unterseite der Tragvorrichtung 23 eine Zahnstange 32 gebildet, mit der ein in der einen und anderen Richtung drehbares Ritzel 33 in Eingriff steht. Das durch einen nicht näher gezeigten Motor angetriebene Ritzel 33 ermöglicht eine Bewegung des Transportsarms 21 in Richtung achsparallel zu den Arbeitszapfen 11, 12. Da­bei wird die Hauptwelle 26 in der ortsfesten Führungshülse 31 gleitend geführt.The carrying device 23 can be moved back and forth overall in the direction transverse to the pivoting plane of the transport arm 21. For this purpose, a toothed rack 32 is formed on the underside of the carrying device 23, with which a pinion 33 rotatable in one and the other direction is in engagement. The pinion 33, which is driven by a motor (not shown in any more detail), enables the transport arm 21 to move in the direction axially parallel to the working pins 11, 12. The main shaft 26 is slidably guided in the stationary guide sleeve 31.

Weiterhin ist, wie in der Patentanmeldung P 37 21 091.2 beschrieben, der Transportzapfen 20 relativ zum Transport­arm 21 bewegbar, und zwar in Längsrichtung desselben. Zu diesem Zweck ist der Transportzapfen 20 in einem Schlitten 34 des Transportarms 21 gelagert. Der Schlitten 34 ist in­nerhalb des als Hohlkörper ausgebildeten Transportarms 21 in dessen Längsrichtung verschiebbar. Zur Durchführung von Stellbewegungen dient ein Stellmotor 35, der am Transport­arm 21 gelagert ist. Eine Motorwelle 36 ist als Spindel ausgebildet und steht in Eingriff mit einer Spindelmutter 37. Diese wiederum ist mit dem Schlitten 34 verbunden. Drehbewegungen der Motorwelle 36 bewirken demnach Stellbe­wegungen des Schlittens 34 in Längsrichtung des Transport­arms 21.Furthermore, as described in patent application P 37 21 091.2, the transport pin 20 is movable relative to the transport arm 21, namely in the longitudinal direction of the same. For this purpose, the transport pin 20 is mounted in a carriage 34 of the transport arm 21. The carriage 34 is displaceable in the longitudinal direction within the transport arm 21 designed as a hollow body. A servomotor 35, which is mounted on the transport arm 21, is used to carry out actuating movements. A motor shaft 36 is designed as a spindle and is in engagement with a spindle nut 37. This in turn is connected to the slide 34. Rotational movements of the motor shaft 36 accordingly result in adjusting movements of the slide 34 in the longitudinal direction of the transport arm 21.

Wie insbesondere aus Fig. 4 ersichtlich, ist der Trans­ portarm 21 im Querschnitt U-förmig ausgebildet. Eine Rück­wand 38 ist mit einer Ausnehmung 39 für den Durchtritt des Transportzapfens 20 versehen. Der Schlitten 34 ist in Sei­tenwänden 40, 41 des Transportarms 21 geführt, und zwar mittels Führungsnuten 42 an den Seitenwänden 40, 41. In die Führungsnuten 42 treten formschlüssig Führungsrippen 43 des Schlittens 34 ein.As can be seen in particular from FIG. 4, the trans portarm 21 in cross section U-shaped. A rear wall 38 is provided with a recess 39 for the passage of the transport pin 20. The slide 34 is guided in side walls 40, 41 of the transport arm 21, specifically by means of guide grooves 42 on the side walls 40, 41. Guide ribs 43 of the slide 34 enter the guide grooves 42 in a form-fitting manner.

Der Transportzapfen 20 ragt einseitig aus dem Schlitten 34 bzw. dem Transportarm 21 heraus und kann dadurch eine Bo­bine 13 aufnehmen (Fig. 5). Die Übergabe derselben an ei­nen der beiden Arbeitszapfen 11, 12 erfolgt bei gleich­achsiger Positionierung des Transportzapfens 20 vor dem betreffenden Arbeitszapfen 11, 12 (Fig. 4). Der Transport­zapfen 20 ist in Axialrichtung verschiebbar, gleitend am Transportarm 21, nämlich in dem Schlitten 34, gelagert. Dieser ist nach beiden Seiten über den Transportarm 21 hinaus verlängert und bildet eine Schubhülse 44, in der der Transportzapfen 20 gelagert ist.The transport pin 20 protrudes on one side from the carriage 34 or the transport arm 21 and can thereby accommodate a bobbin 13 (FIG. 5). The transfer of the same to one of the two working pins 11, 12 takes place with the coaxial positioning of the transport pin 20 in front of the relevant working pin 11, 12 (FIG. 4). The transport pin 20 is slidable in the axial direction, slidably on the transport arm 21, namely in the carriage 34. This is extended on both sides beyond the transport arm 21 and forms a push sleeve 44 in which the transport pin 20 is mounted.

Zur mechanischen, selbsttätigen Übergabe der Bobine 13 an den freien Arbeitszapfen 11, 12 ist der Transportzapfen 20 auf dem freien Ende des Arbeitszapfens 11, 12 abgestützt. Durch Verschiebung des Transportarms 21 in Axialrichtung des Arbeitszapfens 11, 12 wird der Transportzapfen 20 re­lativ in dem Schlitten 34 bzw. der Schubhülse 44 verscho­ben. Die Bobine 13 ist dabei auf dem Vorderende der Schub­hülse 44 abgestützt. Diese drückt die Bobine 13 bei fort­gesetzter Bewegung des Transportarms 21 auf den Arbeits­zapfen 11, 12. In gleichem Maße tritt der Transportzapfen 20 aus der Bobine 13 aus.For the mechanical, automatic transfer of the bobbin 13 to the free working pin 11, 12, the transport pin 20 is supported on the free end of the working pin 11, 12. By moving the transport arm 21 in the axial direction of the working pin 11, 12, the transport pin 20 is relatively moved in the slide 34 or the push sleeve 44. The bobbin 13 is supported on the front end of the thrust sleeve 44. This presses the bobbin 13 with continued movement of the transport arm 21 on the working pin 11, 12. The transport pin 20 emerges from the bobbin 13 to the same extent.

In der Endstellung befindet sich die Bobine 13 auf dem be­treffenden Arbeitszapfen 11, 12 unter Anlage an einem feststehenden Stützteller 45 des Arbeitszapfens 11, 12, Der Stützteller 45 bewirkt eine exakte Positionierung der jeweiligen Arbeits-Bobine 13a auf dem Arbeitszapfen 11, 12, auch während des Abziehens der Materialbahn.In the end position, the bobbin 13 is located on the relevant work pin 11, 12, resting against a fixed support plate 45 of the work pin 11, 12. The support plate 45 effects an exact positioning of the respective work bobbin 13a on the work pin 11, 12, even while the web is being pulled off.

Der Transportzapfen 20 ist federbelastet, nämlich in Rich­tung auf die Ausgangsposition (Fig. 5) in bezug auf den Transportarm 21. Bei dem gezeigten Ausführungsbeispiel ist der Transportzapfen 20 als Hohlkörper ausgebildet. Inner­halb desselben ist eine Rückholfeder 46 angeordnet. Diese stützt sich auf eine Endwandung 47 des Transportzapfens 20 einerseits und auf einer Stützplatte 48 andererseits ab. Die Stützplatte 48 erhält Anlage an einem Querzapfen 49, dessen Enden mit der Schubhülse 44 verbunden sind und der sich quer durch den hohlen Transportzapfen 20 hindurch er­streckt. Letzterer ist zu diesem Zweck an zwei einander gegenüberliegenden Seiten mit einem Führungsschlitz 50 für den Durchtritt der Querzapfens 49 versehen. Wenn nach Übergabe einer Bobine 13 an einen Arbeitszapfen 11, 12 der Transportarm 21 in entgegengesetzter Richtung in die Aus­gangsstellung zurückbewegt wird - durch entsprechende An­triebsbewegung des Ritzels 33 - kehrt selbsttätig auch der Transportzapfen 20 in die Ausgangsposition relativ zum Transportarm 21 zurück (Fig. 5).The transport pin 20 is spring-loaded, namely in the direction of the starting position (FIG. 5) with respect to the transport arm 21. In the exemplary embodiment shown, the transport pin 20 is designed as a hollow body. A return spring 46 is arranged within the same. This is based on an end wall 47 of the transport pin 20 on the one hand and on a support plate 48 on the other hand. The support plate 48 is in contact with a cross pin 49, the ends of which are connected to the thrust sleeve 44 and which extends transversely through the hollow transport pin 20. For this purpose, the latter is provided on two opposite sides with a guide slot 50 for the passage of the cross pin 49. If, after transferring a bobbin 13 to a working pin 11, 12, the transport arm 21 is moved back in the opposite direction into the starting position - by corresponding drive movement of the pinion 33 - the transport pin 20 automatically returns to the starting position relative to the transport arm 21 (FIG. 5) .

Die Bobinen 13 sind, wie allgemein üblich, mit einem Bo­binenkern 14 versehen, auf den das Bahnmaterial gewickelt ist. Der hülsenförmige Bobinenkern 14 besteht vielfach aus Pappe, kann aber auch aus anderen Werkstoffen bestehen. Der Transportzapfen 20 tritt ebenso in den zylindrischen Bobinenkern 14 ein wie die Arbeitszapfen 11 und 12. Nach dem Leerfahren einer Bobine 13 verbleibt der Bobinenkern 14 auf dem Arbeitszapfen 11, 12. Die gezeigte Vorrichtung ist so ausgebildet, daß der Bobinenkern 14 selbsttätig von dem leergefahrenen Arbeitszapfen 11, 12 abgenommen wird.The bobbins 13 are, as is generally customary, provided with a bobbin core 14 on which the web material is wound. The sleeve-shaped bobbin core 14 is often made of cardboard, but can also consist of other materials. The transport pin 20 enters the cylindrical bobbin core 14 as well as the working pins 11 and 12. After a bobbin 13 has been emptied, the bobbin core 14 remains on the working pin 11, 12. The device shown is designed such that the bobbin core 14 automatically moves from the empty one Working pin 11, 12 is removed.

Zu diesem Zweck ist ein Abstreifer vorgesehen, der durch entsprechende Relativbewegung den leeren Bobinenkern 14 in Axialrichtung des Arbeitszapfens 11, 12 von diesem ab­streift. Wie dargestellt, ist jedem Arbeitszapfen 11, 12 ein gesonderter Hülsen-Abstreifer 51, 52 zugeordnet. Jeder dieser Hülsen-Abstreifer 51, 52 weist einen kreisbogenför­migen bzw. halbkreisförmigen Mitnehmer 53 auf. Zum Ab­streifen eines Bobinenkerns 14 von einem Arbeitszapfen 11, 12 wird der Hülsen-Abstreifer 51, 52 in eine Position gefahren, in der der Mitnehmer 53 an einer innen- bzw. vom freien Ende des Arbeitszapfens 11, 12 abliegenden Stirn­fläche 54 zur Anlage kommt (Fig. 1, links). Durch Ver­schieben des Hülsen-Abstreifers 51, 52 in Axialrichtung des Arbeitszapfens 11, 12 wird der Bobinenkern 14 von die­sem abgeschoben. Der Mitnehmer 53 hat zu diesem Zweck eine dem Durchmesser des Bobinenkerns 14 entsprechende Abmes­sung.For this purpose, a wiper is provided, which wipes the empty bobbin core 14 in the axial direction of the working pin 11, 12 by means of a corresponding relative movement. As shown, each working pin is 11, 12 a separate sleeve stripper 51, 52 assigned. Each of these sleeve wipers 51, 52 has an arc-shaped or semicircular driver 53. For stripping a bobbin core 14 from a working pin 11, 12, the sleeve stripper 51, 52 is moved into a position in which the driver 53 comes to rest on an end face 54 that is located inside or away from the free end of the working pin 11, 12 ( 1, left). By moving the sleeve stripper 51, 52 in the axial direction of the working pin 11, 12, the bobbin core 14 is pushed away from it. For this purpose, the driver 53 has a dimension corresponding to the diameter of the bobbin core 14.

Die Hülsen-Abstreifer 51, 52 sind bei der dargestellten Vorrichtung am Transportarm 21 angebracht und werden somit durch diesen betätigt. An zwei gegenüberliegenden Seiten sind jeweils Mitnehmer 53 an einem Tragarm 55 angebracht. Die beiden Tragarme 55 sind an gegenüberliegenden Seiten des Transportarms 21 befestigt, so daß sie durch Schwenk­bewegung und achsparallele Bewegung des Transportarms 21 dem einen oder anderen Arbeitszapfen 11, 12 zugestellt werden können. Zum Abstreifen eines Bobinenkerns 14 von einem Arbeitszapfen 11, 12 wird der Transportarm 21 in der beschriebenen Weise in achsparalleler Richtung bewegt.The sleeve wipers 51, 52 are attached to the transport arm 21 in the device shown and are thus actuated by the latter. Carriers 53 are each attached to a support arm 55 on two opposite sides. The two support arms 55 are fastened on opposite sides of the transport arm 21, so that they can be delivered to one or the other of the working pins 11, 12 by pivoting movement and axially parallel movement of the transport arm 21. In order to strip a bobbin core 14 from a working pin 11, 12, the transport arm 21 is moved in the axis-parallel direction in the manner described.

Die Tragarme 55 sind abgekröpft ausgebildet (Fig. 5). Da­durch liegen die an den Enden angeordneten Mitnehmer 53 in einer Ebene, in der sie zugleich als Anlage für eine auf dem Transportzapfen 20 angeordnete Bobine 13 dienen.The support arms 55 are cranked (Fig. 5). As a result, the drivers 53 arranged at the ends lie in a plane in which they also serve as a system for a bobbin 13 arranged on the transport pin 20.

Mit der beschriebenen Vorrichtung geht eine selbsttätige, voll mechanisierte Versorgung der Arbeitszapfen 11, 12 mit Bobinen 13 wie folgt vonstatten:With the described device, an automatic, fully mechanized supply of the working pins 11, 12 with bobbins 13 takes place as follows:

In der aufrechten, mittigen Position des Transportarms 21 wird der Schlitten 34 mit dem Transportzapfen 20 in eine obere Position 56 (Fig. 6) gefahren. In dieser ist der Transportzapfen 20 auf die jeweils vordere Bobine 13 des Bobinenvorrats 15 ausgerichtet. Durch axial gerichtete Verschiebung kann der Transportzapfen 20 die vordere Bo­bine 13 übernehmen.In the upright, central position of the transport arm 21, the carriage 34 with the transport pin 20 is in one upper position 56 (Fig. 6) moved. In this, the transport pin 20 is aligned with the respective front bobbin 13 of the bobbin supply 15. The transport pin 20 can take over the front bobbin 13 by axially directed displacement.

Damit diese vom Bobinenvorrat 15 freikommt, wird der Schlitten 34 mit Transportzapfen 20 in eine noch höhere, obere Endposition 57 gefahren. Nunmehr kann der Transport­arm 21 in achsparalleler Richtung zurückgefahren werden in eine Ebene, in der der Transportzapfen 20 vor den Enden der Arbeitszapfen 11, 12 sich erstreckt. Der Schlitten 34 wird nun in eine untere Innenposition 58 zurückbewegt. In dieser ist der Transportzapfen 20 exakt auf die Arbeits­zapfen 11, 12 ausgerichtet, wenn der Transportarm 21 vor den einen oder anderen Arbeitszapfen 11, 12 durch Schwenk­bewegung gefahren wird.So that it comes free from the reel supply 15, the carriage 34 is moved with a transport pin 20 into an even higher, upper end position 57. Now the transport arm 21 can be moved back in the axis-parallel direction into a plane in which the transport pin 20 extends in front of the ends of the working pins 11, 12. The carriage 34 is now moved back into a lower inner position 58. In this, the transport pin 20 is exactly aligned with the working pin 11, 12 when the transport arm 21 is moved in front of one or the other working pin 11, 12 by pivoting movement.

In der axialen Ausrichtposition erfolgt in der beschriebe­nen Weise die Übergabe der Bobine 13 an den einen oder an­deren Arbeitszapfen 11, 12, und zwar durch erneute axial gerichtete Verschiebung des Transportarms 21. Die Bobine 13 wird dabei durch den Transportarm 21 mitgenommen bzw. durch die Schubhülse 44.In the axial alignment position, the bobbin 13 is transferred in the manner described to one or the other working pin 11, 12, namely by renewed axial displacement of the transport arm 21. The bobbin 13 is carried along by the transport arm 21 or by the thrust sleeve 44.

Nach Übergabe der "vollen" Bobine 13 an einen Arbeitszap­fen 11, 12 erfolgt der Anschluß der Materialbahn dieser Bobine an die ständig ablaufende Materialbahn des anderen Arbeitszapfens, sobald die laufende Bobine 13a leergefah­ren ist.After the "full" bobbin 13 has been transferred to a working pin 11, 12, the material web of this bobbin is connected to the continuously running material web of the other working pin as soon as the running bobbin 13a has been run empty.

Vor erneuter Beschickung des leergefahrenen Arbeitszapfens 11, 12 wird der Bobinenkern 14 beseitigt. Zu diesem Zweck erfolgt eine achsparallele Verschiebung des Transportarms 21, bis sich der dem betreffenden Arbeitszapfen 11, 12 zu­geordnete Hülsen-Abstreifer 51, 52 bzw. der Mitnehmer 53 in der Ebene hinter der Stirnwandung 54 des Bobinenkerns 14 befindet. Durch Schwenkbewegung des Transportarms 51 wird der Mitnehmer 53 in Abstreifposition gebracht (Fig. 1 bzw. Fig. 2). Durch erneute achsparallele Bewegung des Transportarms 21 wird der Bobinenkern 14 von dem betref­fenden Arbeitszapfen 11, 12 abgeschoben.The bobbin core 14 is removed before the empty working pin 11, 12 is loaded again. For this purpose, an axially parallel displacement of the transport arm 21 takes place until the sleeve stripper 51, 52 assigned to the relevant working pin 11, 12 or the driver 53 in the plane behind the end wall 54 of the bobbin core 14 is located. The driver 53 is brought into the stripping position by pivoting movement of the transport arm 51 (FIG. 1 or FIG. 2). By moving the transport arm 21 again parallel to the axis, the bobbin core 14 is pushed off the relevant working pin 11, 12.

Die Arbeitszapfen 11, 12 sind in bekannter Weise mit ra­dial bewegbaren Klemmbacken 59 ausgestattet. Diese werden in eine radial nach außen gerichtete Klemmposition bewegt, wenn sich eine Bobine 13 auf dem betreffenden Arbeitszap­fen 11, 12 befindet. Zum Aufschieben einer Bobine 13 auf den Arbeitszapfen 11, 12 bzw. zum Abstreifen des leeren Bobinenkerns 14 von dem Arbeitszapfen 11, 12 werden die Klemmbacken 59 radial nach innen bewegt, so daß eine span­nungsfreie Bewegung der Bobine 13 bzw. des Bobinenkerns 14 erfolgen kann.The working pins 11, 12 are equipped in a known manner with radially movable clamping jaws 59. These are moved into a radially outward clamping position when a bobbin 13 is located on the relevant working pin 11, 12. To slide a bobbin 13 onto the working pin 11, 12 or to strip off the empty bobbin core 14 from the working pin 11, 12, the clamping jaws 59 are moved radially inward, so that a tension-free movement of the bobbin 13 or the bobbin core 14 can take place.
