Description

Die Erfindung betrifft eine Verpackungsmaschine zum Herstellen von Verpackungen, insbesondere von Zigaretten-Packungen aus bahnförmigem Verpackungsmaterial , welches von einer Bobine (Arbeitsbobine) auf einem Arbeitszapfen abziehbar ist, wobei neue "volle" Bobinen durch einen Transportzapfen in axialer Ausrichtung vor den Arbeitszapfen förderbar und durch axiales Verschieben auf diesen übertragbar sind.The invention relates to a packaging machine for producing packaging, in particular cigarette packs from sheet-like packaging material, which can be pulled off a bobbin (working bobbin) on a working spigot, with new "full" bobbins being conveyable through and through a transport spigot in axial alignment in front of the working spigot axial displacement are transferable to this.

Bei einer derartigen Verpackungsmaschine werden üblicherweise die Bobinen aus Verpackungsmaterial einem maschinenseitigen Bobinenvorrat entnommen und sodann dem Arbeitszapfen zugestellt. Der Transportzapfen kann auf dem Wege zum Bobinenvorrat bzw. von diesem zum Arbeitszapfen unterschiedliche Bewegungsbahnen zurücklegen. Bei einer Verpackungsmaschine gemäß EP-A-0 260 453 ist der Transportzapfen an einem Transportarm angeordnet. Dieser ist ortsfest gelagert und zwischen dem Bobinenvorrat einerseits und einem von zwei Arbeitszapfen andererseits durch Verschwenken hin- und herbewegbar. Zur Übergabe der Bobine auf den Arbeitszapfen ist es notwendig, daß zum einen die Bobine zwischen zwei Führungen in einer vorgesehenen Position festgehalten wird und zum anderen der Arbeitszapfen und der Transportzapfen in Axialrichtung verschiebbar ausgebildet sind. Der konstruktive Aufbau des Arbeitszapfens ist sehr aufwendig.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 spigot. The transport pin can cover different trajectories on the way to the reel supply or from this to the work pin. In a packaging machine according to EP-A-0 260 453, the transport pin is arranged on a transport arm. This is stationary and can be moved back and forth between the reel supply on the one hand and one of two working pins on the other by swiveling. To transfer the bobbin to the working pin, it is necessary that the bobbin is between two guides in an intended position is held and on the other hand the working pin and the transport pin are designed to be displaceable in the axial direction. The construction of the working pin is very complex.

Aus der GB-A 2 066 789 ist eine spezielle Vorrichtung zum Herstellen von Zigaretten bekannt. Das Zigarettenpapier wird in Form von Bobinen mit Hilfe einer Transporteinrichtung einem Arbeitszapfen zugestellt. Die Übergabe von der Transporteinrichtung auf den Arbeitszapfen erfolgt durch Abschieben vom Transportzapfen. Hierzu sind eigens gelagerte und angetriebene Abschiebeorgane vorgesehen, die nahezu punktweise die Bobine im Bereich des Zigarettenpapiers mit Druck beaufschlagen. In ähnlicher Weise zeigt die EP-A-0 155 863 ein Abschiebeorgan für eine Bobine.A special device for producing cigarettes is known from GB-A 2 066 789. The cigarette paper is fed in the form of bobbins to a work spigot using a transport device. The transfer from the transport device to the working spigot is carried out by pushing off the transport spigot. For this purpose, specially mounted and driven push-off devices are provided, which press the bobbin with pressure almost at certain points in the area of the cigarette paper. Similarly, EP-A-0 155 863 shows a push-off device for a bobbin.

Die Aufgabe der Erfindung ist es daher, eine Verpackungsmaschine zu schaffen, die einen kontinuierlichen und zuverlässigen Bewegungsablauf beim Wechseln von Bobinen und bei zugleich einfachem konstruktivem Aufbau ermöglicht.The object of the invention is therefore to provide a packaging machine which enables a continuous and reliable sequence of movements when changing bobbins and at the same time has a simple construction.

Zur Lösung dieser Aufgabe ist die erfindungsgemäße Verpackungsmaschine dadurch gekennzeichnet, daß der Transportzapfen in einer Schubhülse koaxial gelagert ist und daß die Schubhülse zur Überführung der Bobine vom Transportzapfen auf den Arbeitszapfen in Richtung auf den Arbeitszapfen bewegbar ist unter Mitnahme der Bobine und unter Anlage an einem radial innenliegenden Bereich der Bobine.To achieve this object, the packaging machine according to the invention is characterized in that the transport pin is mounted coaxially in a push sleeve and that the push sleeve for transferring the bobbin from the transport pin to the working pin is movable in the direction of the working pin while taking the bobbin and bearing against a radial inner area of the bobbin.

Das mechanische Fördermittel zur Übergabe der Bobine vom Transportzapfen an den Arbeitszapfen ist erfindungsgemäß eine koaxial zum Transportzapfen bewegbare Schubhülse, die die Bobine vom Transportzapfen auf den unmittelbar an das freie Ende des Transportzapfens anschließenden Arbeitszapfen schiebt. Dabei wird auf einen radial innenliegenden Bereich der Bobine (Bobinenkern) Druck ausgeübt. Durch die Lagerung der Schubhülse auf dem Transportzapfen sind eine sichere Führung und ein einfacher Aufbau gewährleistet.According to the invention, the mechanical conveying means for transferring the bobbin from the transport spigot to the working spigot is a thrust sleeve which can be moved coaxially to the transport spigot and which pushes the bobbin from the transport spigot onto the working spigot directly adjoining the free end of the transport spigot. Pressure is exerted on a radially inner area of the bobbin (bobbin core). The storage of the thrust sleeve on the transport pin ensures safe guidance and simple construction.

Die Förderbewegung des Schiebers bzw. der Schubhülse wird 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 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 der Schubhülse. 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 thrust sleeve with it. This is moved relative to the transport pin, taking the bobbin with it until it sits on the working pin.

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 elements for bobbins and bobbin tubes.

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 bobbin 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 accommodate a bobbin 13.

Die Bobinen 13 sind gewickelte Rollen bahnförmigen Verpackungsmaterials, z. B. 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 Arbeitzapfen 11 bereitgehaltenen, "vollen" Bobine 13 abgezogen.The reels 13 are wound rolls of sheet-like packaging material, e.g. B. foil, plastic film or the like. For the processing of the packaging material within the packaging machine, the web-shaped packaging material is drawn off from a running (working) reel 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 supply 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 working pins 11, 12 is accomplished by a transport pin 20. This picks up the front bobbin 13 in the bobbin stock, 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 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 displaceable. 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), allows the transport arm 21 to move in the direction axially parallel to the working pins 11, 12. The main shaft 26 is guided in a sliding manner 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 can be moved relative to the transport arm 21, namely in the longitudinal direction thereof. For this purpose, the transport pin 20 is mounted in a carriage 34 of the transport arm 21. The carriage 34 can be displaced in the longitudinal direction within the transport arm 21, which is 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 bring about adjusting movements of the slide 34 in the longitudinal direction of the transport arm 21.

Wie insbesondere aus Fig. 4 ersichtlich, ist der Transportarm 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 transport arm 21 U-shaped in cross section. A rear wall 38 is provided with a recess 39 for the passage of the transport pin 20. The carriage 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 carriage 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 displaceable 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 thrust 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 spigot 11, 12, bearing against a fixed support plate 45 of the work spigot 11, 12. The support plate 45 effects an exact positioning of the respective work bobbin 13a on the work spigot 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 so 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 against 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 attached to a support arm 55 on two opposite sides. The two support arms 55 are attached to 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. To strip a bobbin core 14 from a working pin 11, 12, the transport arm 21 is moved in the direction described in the axis-parallel direction.

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:
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.With the device described, an automatic, fully mechanized supply of the working pins 11, 12 with bobbins 13 takes place as follows:
In the upright, central position of the transport arm 21, the carriage 34 with the transport pin 20 in one upper position 56 (Fig. 6) moved. In this, the transport pin 20 is aligned with the respective front reel 13 of the reel 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 bobbin 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 an 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.Before the empty working pin 11, 12 is loaded again, the bobbin core 14 is removed. 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 is 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 (FIGS. 1 and 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 the empty bobbin core 14 off 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.
