Description

Die Erfindung betrifft eine Vorrichtung zur Zuführung von Bobinen von Verpackungsmaterial an eine Bobinen-Wechselvorrichtung einer Verpackungsmaschine gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for feeding bobbins of packaging material to a bobbin changing device of a packaging machine according to the preamble of patent claim 1.

Leistungsfähige Verpackungsmaschinen müssen in ausreichendem Umfange mit Verpackungsmaterial versehen werden. Bei Zigaretten-Verpackungsmaschinen muß Stanniol als Innenumhüllung der Zigaretten, Papier (für Weichbecher-Packungen) und Zellglas bzw. Kunststoffolie zur Verfügung gestellt werden. Dieses Material wird üblicherweise als gewickelte Rolle (Bobine) an der Verpackungsmaschine angebracht und entsprechend dem Verbrauch an Verpackungsmaterial abgezogen. Die Bobinen werden dabei durch rotierende, einseitig gelagerte Tragzapfen aufgenommen, die in eine durch einen zylindrischen Kern (überlicherweise Pappkern) gebildete Mittenöffnung der Bobine eintreten.Efficient packaging machines must be provided with sufficient packaging material. In the case of cigarette packaging machines, tin foil must be made available as the inner wrapping of the cigarettes, paper (for soft cup packs) and cellophane or plastic film. This material is usually attached to the packaging machine as a wound roll (bobbin) and drawn off according to the consumption of packaging material. The bobbins are rotating by one-sided supported trunnions added, which enter into a central opening of the bobbin formed by a cylindrical core (usually cardboard core).

Die Erfindung befaßt sich mit der weitgehend selbsttätigen Zuführung von Bobinen zu einer Verpackungsmaschine sowie mit der Übergabe derselben an eine mit Tragzapfen ausgerüstete Bobinen-Wechselvorrichtung der Verpackungsmaschine.The invention is concerned with the largely automatic feeding of bobbins to a packaging machine and with the transfer thereof to a bobbin changing device of the packaging machine equipped with trunnions.

Aus der GB-A-2 167 047 ist eine Vorrichtung bekannt, bei der Bobinen aus einer waagerechten Ebene mittels einer schwenkbaren Einrichtung in eine hierzu senkrechte Ebene gefördert und einer Aufnahme mit Tragzapfen zugeführt werden. Die Aufnahme enthält zugleich einen aufwendigen Verriegelungs- und Positioniermechanismus, um die Bobine in der letztlich gewünschten Position zu halten.From GB-A-2 167 047 a device is known in which bobbins are conveyed from a horizontal plane by means of a pivotable device into a plane perpendicular thereto and are fed to a receptacle with trunnions. The receptacle also contains a complex locking and positioning mechanism to hold the bobbin in the ultimately desired position.

Weiterhin ist aus der EP-A-0 155 863 eine Vorrichtung bekannt, bei der ein eine Bobine abgebender Bobinenträger axial verschiebbar ist.Furthermore, a device is known from EP-A-0 155 863, in which a bobbin carrier that delivers a bobbin is axially displaceable.

Der Erfindung liegt die Aufgabe zugrunde, eine zuverlässige, leistungsfähige Überführung bzw. Übergabe der Bobinen ohne manuellen Eingriff zu gewährleisten. Erfindungsgemäß ergibt sich die Lösung der Aufgabe durch die kennzeichnenden Merkmale des Patentanspruchs 1. Danach ist an dem schwenkbaren Bobinenförderarm ein quer abstehender, ebenfalls axial verschiebbarer Fördertragbolzen zur Aufnahme der Bobine während der Überführung angeordnet. Der Bobinenförderarm wird mit einer (neuen) Bobine derart vor den zu beschickenden Tragzapfen der Bobinen-Wechselvorrichtung bewegt, daß Tragzapfen und Fördertragzapfen achsgleich liegen, mit freien Stirnenden benachbart zueinander. Der zu beschickende Tragzapfen wird nun in Axialrichtung ausgefahren, während der Fördertragzapfen in gleichem Maße zurückgezogen wird. Hierdurch erfolgt die Übergabe der Bobine, ohne diese zu bewegen. Manuelle Eingriffe sind hierfür nicht erforderlich. Zugleich erfolgt die Übergabe der Bobine in besonders zuverlässiger Weise.The invention has for its object to ensure a reliable, efficient transfer or transfer of the bobbins without manual intervention. According to the invention, the object is achieved by the characterizing features of patent claim 1. Thereafter, a transversely projecting, likewise axially displaceable conveyor support bolt for receiving the bobbin is arranged on the pivotable bobbin conveyor arm during the transfer. The bobbin conveyor arm is moved with a (new) bobbin in front of the trunnion to be loaded in the bobbin changing device in such a way that the trunnion and the conveyor trunnion are axially aligned, with free end faces adjacent to one another. The trunnion to be loaded is now extended in the axial direction, while the conveyor trunnion is withdrawn to the same extent. As a result, the bobbin is handed over without moving it. Manual intervention is not necessary for this. At the same time, the handover of the Bobine in a particularly reliable way.

Die Tragzapfen bzw. Fördertragzapfen können in geeigneter Weise zur Durchführung der Axialbewegungen antreibbar sein. Vorzugsweise werden die Tragzapfen der Bobinen-Wechselvorrichtung durch Druckluft betätigt, während der Fördertragzapfen des Bobinenförderarms mechanisch bzw. elektromechanisch durch einen E-Motor über ein Zahnradgetriebe verstellt wird.The trunnion or conveyor trunnion can be driven in a suitable manner to carry out the axial movements. The support pins of the bobbin changing device are preferably actuated by compressed air, while the conveyor support pin of the bobbin conveyor arm is adjusted mechanically or electromechanically by an electric motor via a gear transmission.

Die Tragzapfen der Bobinen-Wechselvorrichtung sind mit weiteren Besonderheiten ausgerüstet. So ist mit dem Tragzapfen jeweils eine Spannbremse integriert, die nach Maßgabe der in der ablaufenden Bahn festgestellten Spannung betätigt wird, um sicherzustellen, daß die Bahn stets mit annähernd gleicher Spannung gefördert wird.The trunnions of the bobbin changing device are equipped with other special features. For example, a tensioning brake is integrated with the trunnion, which is actuated in accordance with the tension determined in the running web to ensure that the web is always conveyed with approximately the same tension.

Des weiteren sind die Tragzapfen im Bereich der Anlage der Bobine mit radial bewegbaren Klemmorganen zum lösbaren Fixieren der Bobine versehen. Diese werden erfindungsgemäß pneumatisch betätigt, und zwar über den Tragzapfen bzw. eine diesem zugeordnet Kolbenstange.Furthermore, the trunnions are in the area of the bobbin system with radially movable clamping members for releasable Fix the bobbin provided. According to the invention, these are actuated pneumatically, specifically via the support pin or a piston rod assigned to it.

Dem Bobinenförderer (Bobinenförderarm) ist nach einem weiteren Merkmal der Erfindung ein Vorförderer zugeordnet, der eine Mehrzahl von Bobinen aufzunehmen vermag und so als Bobinenspeicher dient. Die jeweils vordere Bobine auf dem Vorförderer wird in einer Übernahmeposition fixiert, so daß der Fördertragzapfen des Bobinenförderarms durch Radialbewegung in die Mittenöffnung der Bobine eintreten kann.According to a further feature of the invention, the bobbin conveyor (bobbin conveyor arm) is assigned a pre-conveyor which is able to accommodate a plurality of bobbins and thus serves as a bobbin store. The respective front bobbin on the pre-conveyor is fixed in a take-over position so that the conveyor support pin of the bobbin conveyor arm can enter the center opening of the bobbin by radial movement.

Weitere Merkmale der Erfindung betreffen die Ausbildung der Bobinen-Wechselvorrichtung, des Bobinenförderarms nebst Fördertragzapfen sowie den Vorförderer.Further features of the invention relate to the design of the bobbin changing device, the bobbin conveyor arm together with the conveyor support pin, and the pre-conveyor.

Fig. 1 zeigt schematisiert in Seitenansicht eine Verpackungsmaschine 10 für Zigaretten, insbesondere zur Herstellung von Klappschachteln. Für diese Verpackungen wird Verpackungsmaterial in größerem Umfange ständig verbraucht. Dies gilt insbesondere auch für eine Innenumhüllung der Zigaretten aus Stanniol. Dieses Verpackungsmaterial wird in Form von Rollen bzw. Bobinen 11 der Verpackungsmaschine 10 zugestellt und dann zu einzelnen Zuschnitten verarbeitet.Fig. 1 shows schematically in side view a packaging machine 10 for cigarettes, in particular for the production of hinged boxes. Large quantities of packaging material are constantly used for this type of packaging. This applies in particular to the inner wrapping of the tinfoil cigarettes. This packaging material is delivered to the packaging machine 10 in the form of rolls or reels 11 and then processed into individual blanks.

Für die Zuführung der Bobinen 11 ist der Verpackungsmaschine 10 eine Bobinen-Wechselvorrichtung 12 zugeordnet. Diese besteht im vorliegenden Falle aus einem ortsfest gelagerten, schwenkbaren Förderarm 13, der jeweils einzelne Bobinen 11 von einer Übergabestation 14 aufnimmt und jeweils einem von zwei maschinenseitigen Tragzapfen 15, 16 zustellt. Diese sind an einem Bobinentraggestell 17 der Verpackungsmaschine 10 einseitig abstehend und drehbar gelagert. Einer der Tragzapfen (hier der Tragzapfen 15) trägt die ablaufende, "aktive" Bobine 11a, während der andere Tragzapfen 16 für die Zuführung einer neuen, frischen Bobine 11b bereit ist.A bobbin changing device 12 is assigned to the packaging machine 10 for feeding the bobbins 11. In the present case, this consists of a stationary, pivotable conveyor arm 13, which receives individual bobbins 11 from a transfer station 14 and delivers one of two machine-side support pins 15, 16. These are supported on one side of a bobbin support frame 17 of the packaging machine 10 and are rotatable. One of the trunnions (here the trunnion 15) carries the running, "active" bobbin 11a, while the other trunnion 16 is ready for feeding a new, fresh bobbin 11b.

Die Übergabestation 14 ist Teil eines Zuförderers 18, der hier oberhalb der Verpackungsmachine 10 angeordnet und als schräg nach unten in Richtung auf die Übergabestation 14 abfallende Rollbahn für die Bobinen 11 ausgebildet ist. Diese werden in aufrechter Stellung (in aufrechter Ebene) auf dem Zuförderer 18 abgesetzt und bewegen sich selbsttätig durch das Gefälle nach Maßgabe der Weiterförderung zur unteren Übergabestation 14.The transfer station 14 is part of a feed conveyor 18, which is arranged here above the packaging machine 10 and is designed as a runway for the bobbins 11 that slopes obliquely downward in the direction of the transfer station 14. These are placed in an upright position (in an upright plane) on the feed conveyor 18 and move automatically through the gradient to the lower transfer station 14 in accordance with the further conveyance.

Der Zuförderer 18 besteht aus einem unteren, im Querschnitt winkelförmigen Tragprofil mit einem horizontalen bzw. schräg nach unten gerichteten Tragschenkel 19 und einem seitlichen, aufrechten Führungsschenkel 20. Die Bobinen 11 werden im Bereich einer Aufgabestation 21 auf das obere Ende des Zuförderers 18 aufgesetzt und im unteren Bereich, vor der Übergabestation 14 durch einen auf- und abbewegbaren Anschlag 22 gehalten. Jeweils eine untere bzw. vordere Bobine wird - auf dem Tragschenkel 19 ablaufend - der Übergabestation 14 zugeführt und hier durch einen in Bewegungsrichtung der Bobinen 11 bewegbaren Endanschlag 23 positionsgenau fixiert. Der Anschlag 22 gibt durch Aufwärtsbewegen und anschließende Abwärtsbewegung in die Stopposition jeweils nur eine Bobine zur Bewegung in die Übergabestation 14 frei.The feed conveyor 18 consists of a lower, cross-sectionally angular support profile with a horizontal or obliquely downwardly directed support leg 19 and a lateral, upright guide leg 20. The bobbins 11 are placed in the area of a feed station 21 on the upper end of the feed conveyor 18 and in the lower area, in front of the transfer station 14, by a stop 22 which can be moved up and down held. In each case, a lower or front bobbin is fed to the transfer station 14, running on the support leg 19, and is fixed here in an exact position by an end stop 23 which can be moved in the direction of movement of the bobbins 11. The stop 22 releases only one bobbin for movement into the transfer station 14 by moving upwards and then moving downwards into the stop position.

Die Bobinen 11 werden dem Zuförderer 18 durch einen Hauptförderer 24 zugeführt, der hier als innerhalb des Verpackungsbetriebes umlaufender Kreisförderer ausgebildet ist.The bobbins 11 are fed to the feed conveyor 18 by a main conveyor 24, which is designed here as a circular conveyor rotating within the packaging company.

Im Bereich der Übergabestation 14 werden die Bobinen 11 jeweils zusätzlich fixiert, und zwar durch eine Oberführung 24, die im Querschnitt ebenfalls winkelförmig ausgebildet ist mit einem seitlichen Stützschenkel 26. Bei der Übernahme durch den Förderarm 13 legt sich die Bobine abstützend an den Führungsschenkel 20 des Zuförderers 18 und den Stützschenkel 26 der Oberführung 25 an. Nach Übernahme der Bobine 11 durch den Förderarm 13 wird dieser im Uhrzeigersinn oder im Gegenuhrzeigersinn verschwenkt zu dem einen oder anderen Tragzapfen 15, 16. Bei einer Bewegung im Gegenuhrzeigersinn wird nach Aufnahme der Bobine 11 durch den Förderarm 13 ein Endstück 27 des Zuförderers 18 zur Seite bewegt (strichpunktierte Darstellung in Fig. 4). Der Förderarm 13 kann nunmehr frei mit der Bobine im Gegenuhrzeigersinn bewegt werden.In the area of the transfer station 14, the bobbins 11 are each additionally fixed, specifically by an upper guide 24, which is also angled in cross-section with a lateral support leg 26. When taken over by the conveyor arm 13, the bobbin is supported on the guide leg 20 of the Feed conveyor 18 and the support leg 26 of the top guide 25. After the bobbin 11 has been taken over by the conveyor arm 13, the latter is pivoted clockwise or counterclockwise to one or the other supporting pin 15, 16. When moving the bobbin 11 by the conveyor arm 13, an end piece 27 of the feed conveyor 18 becomes aside moved (dash-dotted representation in Fig. 4). The conveyor arm 13 can now be moved freely with the bobbin in the counterclockwise direction.

Der Förderarm 13 ist zur Aufnahme einer Bobine 11 für den Transport mit einem einseitig, quer abstehenden Förderzapfen 28 versehen. Dieser tritt - wie der Tragzapfen 15, 16 - von einer Seite her in die Mittenöffnung 42 der Bobine 11 ein und trägt diese. Für die Aufnahme und Übergabe von Bobinen sind der Tragzapfen 15, 16 sowie der Förderzapfen 28 axial verschiebbar.The conveyor arm 13 is provided with a one-sided, transversely projecting conveyor pin 28 for receiving a bobbin 11 for transport. This occurs - like the trunnion 15, 16 - from one side into the center opening 42 of the bobbin 11 and carries it. For receiving and transferring bobbins, the support pin 15, 16 and the feed pin 28 are axially displaceable.

In Fig. 2 ist ein Tragzapfen 15, 16 im Axialschnitt gezeigt mit dem Förderzapfen 28 bei der Überführung einer Bobine 11. Der Tragzapfen 15, 16 ist in einem langgestreckten, vorzugsweise zylindrischen Gehäuse 29 gelagert. Dieses ist fest mit dem Bobinentraggestell 17 der Verpackungsmaschine 10 verbunden. Der Tragzapfen 15, 16 ist in dem Gehäuse 29 axial verschiebbar. Fig. 2 zeigt die zurückgezogene Ausgangsposition. An dem eigentlichen, die Bobine 11 aufnehmenden und aus dem Gehäuse 29 in ausgefahrener Position herausragenden Tragzapfen 15, 16 schließt innerhalb des Gehäuses 19 eine Kolbenstange 30 an. Diese wiederum ist am vom Tragzapfen 15, 16 abliegenden Endbereich mit einer Querschnittsverbreiterung in Gestalt eines ringsherumlaufenden Kragens 31 versehen. Dieser bildet einen Kolben, der ringsherum mit einer Dichtung 32 versehen in einer im Querschnitt ringförmigen Zylinderkammer 33 des Gehäuses 29 verschiebbar ist.2 shows a support pin 15, 16 in axial section with the support pin 28 when a bobbin 11 is transferred. The support pin 15, 16 is mounted in an elongate, preferably cylindrical housing 29. This is firmly connected to the bobbin support frame 17 of the packaging machine 10. The support pin 15, 16 is axially displaceable in the housing 29. Fig. 2 shows the retracted starting position. A piston rod 30 is connected within the housing 19 to the actual support pin 15, 16 which receives the bobbin 11 and protrudes from the housing 29 in the extended position. This in turn is provided at the end region remote from the support pin 15, 16 with a cross-sectional widening in the form of a collar 31 running all around. This forms a piston which can be displaced all around with a seal 32 in a cylindrical chamber 33 of housing 29 with an annular cross section.

In der gezeigten Ausgangsstellung liegt der Kragen 31 an einem Ansatz 34 des Gehäuses 29 an, gebildet durch eine Querschnittsverengung in diesem Bereich. Die Druckmittelzufuhr erfolgt über einen im Gehäuse 29 gebildeten Ringkanal 35, der über einen Leitungsansatz 36 mit Druckluft versorgt wird.In the starting position shown, the collar 31 bears against a shoulder 34 of the housing 29, formed by a cross-sectional constriction in this area. The pressure medium is supplied via an annular channel 35 formed in the housing 29, which is supplied with compressed air via a line extension 36.

Zur Axialverschiebung des Tragzapfens 15, 16 in die Arbeitsstellung wird der Kragen 31 durch Druckluft bis zur Anlage an ein Gegenlager am Ende der Zylinderkammer 33 verschoben, im vorliegenden Falle durch ein Axialkugellager 37 gebildet. Der Kragen 31 stützt sich auf diesem Axialkugellager 37 ab und ermöglicht dadurch die Drehung des Tragzapfens 15, 16 einschließlich Kolbenstange 30 zum Abziehen der Bahn von der Bobine 11 unter Drehung derselben.For the axial displacement of the support pin 15, 16 into the working position, the collar 31 is displaced by compressed air until it abuts against a counter bearing at the end of the cylinder chamber 33, in the present case formed by an axial ball bearing 37. The collar 31 is supported on this axial ball bearing 37 and thereby enables the rotation of the support pin 15, 16 including the piston rod 30 to pull off the web from the reel 11 underneath Rotation of the same.

Für die Rückbewegung des Kragens 31 und damit des Tragzapfens 15, 16 in die gezeigte Ausgangsstellung ist neben dem Axialkugellager 37 ein weiterer Leitungsansatz 38 für Druckluft angebracht. Die hier zugeführte Druckluft kann über einen Ringspalt 39 sowie über Längsnuten 40 in der Kolbenstange 30 in dem beschriebenen Sinne wirksam werden.For the return movement of the collar 31 and thus the support pin 15, 16 into the starting position shown, a further line attachment 38 for compressed air is attached in addition to the axial ball bearing 37. The compressed air supplied here can be effective in the described manner via an annular gap 39 and via longitudinal grooves 40 in the piston rod 30.

Der Tragzapfen 15, 16 ist mit Halterorganen versehen, die in ausgefahrener Stellung des Tragzapfens 15, 16 in Radialrichtung wirksam werden und die Bobine 11 auf dem Tragzapfen 15, 16 fixieren. Bei dem gezeigten Ausführungsbeispiel sind im Auflagerbereich der Bobine 11 in Umfangsrichtung verteilt angeordnete (vier) Klemmbacken 41 vorgesehen, die durch Radialverschiebung an der Innenseite einer Mittenöffnung 42 der Bobine 11 zur Anlage kommen. Die Bobinen 11 sind üblicherweise mit einem zylindrischen Kern, nämlich einer Kernhülse 43 versehen, an der die Klemmbacken 41 zur Halterung der Bobine 11 anliegen.The trunnion 15, 16 is provided with holder members which are effective in the extended position of the trunnion 15, 16 in the radial direction and fix the bobbin 11 on the trunnion 15, 16. In the exemplary embodiment shown, (four) clamping jaws 41 are provided in the support area of the bobbin 11, which are distributed in the circumferential direction and come to bear on the inside of a central opening 42 of the bobbin 11 due to radial displacement. The bobbins 11 are usually provided with a cylindrical core, namely a core sleeve 43, against which the clamping jaws 41 bear to hold the bobbin 11.

Die Klemmbacken 41 werden pneumatisch betätigt. Zu diesem Zweck sind die Klemmbacken 41 in einer Ausdrehung bzw. ringsherumlaufenden Ausnehmung 44 des Tragzapfens 15,16 gelagert. Die Klemmbacken 41 sind, wie insbesondere aus Fig. 5 ersichtlich, auf einer Manschette 45 aus elastischem Wirkstoff, z.B. Gummi, abgestützt. Die Manschette 45 umgibt den Tragzapfen 15, 16 im Bereich dieser Querschnittsverminderung. Von innen her kann die an ihren Enden durch nach innen gerichtete Dichtschenkel 46 abgedichtete Manschette durch Druckluft beaufschlagt und so unter radialer Querschnittsvergrößerung aufgeweitet werden. Diese allseitige radiale Querschnittsvergrößerung der Manschette 45 führt zu einer entsprechenden Radialbewegung der Klemmbacken 41 gegen die Bobine 11. Die Klemmbacken 41 sind dabei im Querschnitt T-förmig ausgebildet mit innenliegenden, gebogenen Stützflanschen 47, die an der Manschette 45 anliegen. Die stegförmigen Klemmbacken 41 treten durch Schlitze 48 im Mantel 49 des Tragzapfens 15, 16 hindurch.The jaws 41 are actuated pneumatically. For this purpose, the clamping jaws 41 are mounted in a recess or a recess 44 of the support pin 15, 16 running around them. The clamping jaws 41, as can be seen in particular from FIG. 5, are supported on a sleeve 45 made of an elastic active substance, for example rubber. The sleeve 45 surrounds the support pin 15, 16 in the area of this reduction in cross section. From the inside, the cuff, which is sealed at its ends by inwardly directed sealing legs 46, can be acted upon by compressed air and thus expanded with a radial increase in cross-section. This radial cross-sectional enlargement of the sleeve 45 on all sides leads to a corresponding radial movement of the clamping jaws 41 against the bobbin 11. The clamping jaws 41 are T-shaped in cross section with internal, curved support flanges 47 which abut the cuff 45. The web-shaped clamping jaws 41 pass through slots 48 in the jacket 49 of the trunnion 15, 16.

Die Versorgung der vorstehend beschriebenen Halteeinrichtung mit Druckluft erfolgt über die Kolbenstange 30. Diese setzt sich mit einem Kolbenfortsatz 50 in einer Druckluftkammer 51 fort. Diese ist in einer entsprechenden Verlängerung des Gehäuses 29 im Anschluß an die Zylinderkammer 33 gebildet. Am freien Ende ist der Kolbenfortsatz 50 mit einer zylindrischen Kolbenverdickung 52 versehen.The holding device described above is supplied with compressed air via the piston rod 30. This continues with a piston extension 50 in a compressed air chamber 51. This is formed in a corresponding extension of the housing 29 following the cylinder chamber 33. At the free end, the piston extension 50 is provided with a cylindrical piston thickening 52.

Die Zufuhr von Druckluft zur Druckluftkammer 51 erfolgt über einen Leitungsanschluß 53 in einer Endwandung des Gehäuses 29. Die Druckluft gelangt über einen Axialkanal 54 im Kolbenfortsatz 50 sowie in der Kolbenstange 30 bis in den Bereich der Manschette 45. Hier sind am Axialkanal 54 quergerichtete Verteilerkanäle 55 gebildet, die an der Innenseite der Manschette 45 münden und die beschriebene Aufweitung derselben durch Druckluft bewirken. Die Übertragung der Druckluft zur Manschette 45 erfolgt bei einer Position der Kolbenverdickung 52 im Bereich von Dichtungen 56 in der Druckluftkammer 51.Compressed air is supplied to the compressed air chamber 51 via a line connection 53 in an end wall of the housing 29. The compressed air passes through an axial channel 54 in the piston extension 50 and in the piston rod 30 to the area of the sleeve 45. Here there are transverse distribution channels 55 on the axial channel 54 formed, which open on the inside of the sleeve 45 and cause the described expansion of the same by compressed air. The compressed air is transferred to the sleeve 45 when the piston thickening 52 is in the position of seals 56 in the compressed air chamber 51.

In die aus Tragzapfen 15, 16 und Gehäuse 29 bestehende Einheit ist eine Spannbremse 57 integriert, die zur Aufrechterhaltung einer bestimmten, vorgegebenen Spannung in der von der Bobine 11 ablaufenden Bahn dient. Die Spannbremse 57 ist hier elektromagnetisch ausgebildet. In einer Ringausnehmung 58 des Gehäuses 29 ist ein Bremsring 59 axial verschiebbar gelagert. Dieser wird bei Stromzufuhr zu der Spannbremse 57 gegen einen Gegenring 69 gezogen, wobei ringförmige Bremsflächen 61 zur Anlage und damit zur Wirkung miteinander kommen. Der Gegenring 60 ist mit einer elektrischen Wicklung versehen, die über Leitungen 62 gespeist wird.In the unit consisting of trunnions 15, 16 and housing 29, a tensioning brake 57 is integrated, which serves to maintain a certain, predetermined tension in the path running off the bobbin 11. The tensioning brake 57 is electromagnetic here. A brake ring 59 is axially displaceably mounted in an annular recess 58 of the housing 29. When power is supplied to the tensioning brake 57, this is pulled against a counter ring 69, annular braking surfaces 61 coming into contact and thus acting together. The counter ring 60 is provided with an electrical winding which is fed via lines 62.

Die Spannbremse 57 wird durch die Bahn selbst gesteuert, nämlich nach Maßgabe der in dieser gemessenen Spannung. Die Bahn wird zu diesem Zweck über Schwingen oder Tänzerwalzen bekannter Ausführung geführt. Veränderungen in der Position dieser Umlenkorgane bewirken eine Betätigung der Spannbremse 57 in anziehendem oder entlastendem Sinne.The tensioning brake 57 is controlled by the web itself, namely in accordance with the tension measured therein. For this purpose, the web is guided over rockers or dancer rollers of known design. Changes in the position of these deflection elements cause the tensioning brake 57 to be actuated in an attracting or relieving sense.

Der Bremsring 59 ist zur Drehsicherung mit der Kolbenstange 30 formschlüssig verbunden. Radial nach innen gerichtete Haltezähne 63 treten an einander gegenüberliegenden Seiten in die bereits erwähnten Längsnuten 40 der Kolbenstange 30 ein und ermöglichen die Relativverschiebung derselben beim Ein- und Ausfahren des Tragzapfens 15, 16.The brake ring 59 is positively connected to the piston rod 30 to prevent rotation. Radially inwardly directed retaining teeth 63 enter the already mentioned longitudinal grooves 40 of the piston rod 30 on opposite sides and enable the relative displacement thereof when the trunnion 15, 16 is extended and retracted.

Bei der Übergabe einer Bobine 11 an die Bobinen-Wechselvorrichtung 12 der Verpackungsmaschine 10 sind die Axialbewegungen der Tragzapfen 15, 16 einerseits und des Förderzapfens 28 am Förderarm 13 andererseits aufeinander abgestellt. Die Bobine 11 wird durch den Förderarm 13 positionsgenau vor den zurückgezogenen Tragzapfen 15,16 gefördert, und zwar ohne Axialverschiebung der Bobine 11. Diese kommt zur Anlage an einer dem Bobinenzapfen 15,16 zugeordneten, tellerförmigen Seitenführung 64. Diese ist mit einer zentrischen Öffnung 65 für den passenden Durchtritt des Tragzapfens 15, 16 versehen. Die Seitenführung ist drehbar am bzw. im Gehäuse 29 gelagert, im vorliegenden Falle durch ein hohles, zylinderförmiges Achsstück 66, welches axial unverschiebbar, drehbar in einer entsprechenden Ausnehmung des Gehäuses 29 gelagert ist, und zwar den Tragzapfen 15, 16 in der zurückgezogenen Stellung umschließend.When a bobbin 11 is transferred to the bobbin changing device 12 of the packaging machine 10, the axial movements of the support pins 15, 16 on the one hand and the feed pin 28 on the feed arm 13 on the other hand are adjusted to one another. The bobbin 11 is conveyed by the conveyor arm 13 in the exact position in front of the retracted support pin 15, 16, namely without axial displacement of the bobbin 11. This comes into contact with a plate-shaped side guide 64 assigned to the bobbin pin 15, 16. This has a central opening 65 provided for the appropriate passage of the trunnion 15, 16. The side guide is rotatably mounted on or in the housing 29, in the present case by a hollow, cylindrical axle piece 66, which is axially immovable, rotatably mounted in a corresponding recess in the housing 29, specifically surrounding the support pin 15, 16 in the retracted position .

Nach Zustellung einer Bobine 11 zum Tragzapfen 15, 16 (Fig. 2) beginnt die Axialverschiebung des Tragzapfens 15, 16 und korrespondierend die Rückziehbewegung des Förderzapfens 28. Bei dem vorliegenden Ausführungsbeispiel wird letzterer elektromechanisch angetrieben. Der Förderzapfen 28 wird dabei in einem an dem Förderarm 13 angebrachten Hohlzylinderstück 67 geführt. An diesem ist ein Antriebsmotor angebracht, nämlich ein Stellmotor 68. Dieser steht über ein Ritzel 69 in Antriebsverbindung mit einer im rückwärtigen Teil des Förderzapfens 28 eingearbeiteten Zahnnut 70.After a bobbin 11 has been delivered to the trunnion 15, 16 (FIG. 2), the axial displacement of the trunnion 15, 16 and correspondingly the retraction movement of the conveyor spigot 28 begins. In the present exemplary embodiment, the latter is driven electromechanically. The The conveyor pin 28 is guided in a hollow cylinder piece 67 attached to the conveyor arm 13. A drive motor is attached to this, namely a servomotor 68. This is in drive connection via a pinion 69 with a tooth groove 70 machined in the rear part of the conveyor pin 28.

Der Stellmotor 68 wird durch den (ausfahrenden) Tragzapfen 15, 16 betätigt. Zu diesem Zweck ist der Stellmotor 68 über in der Achse des Förderzapfens 28 verlaufende Steuerleitungen 71 mit einem in einer Axialbohrung 72 angeordneten Betätigungsorgan verbunden, nämlich einem elektrischen Initiator 73. Dieses in Aufbau und Arbeitsweise bekannte Schaltorgan wird durch ein Metallstück 74 an der Stirnseite des Tragzapfens 15, 16 beaufschlagt, wenn dieser in Axialrichtung verschoben wird. Der Stellmotor 68 wird nun eingeschaltet und bewegt seinerseits den Förderzapfen 28 in die zurückgezogene Position (nach links in bezug auf Fig. 2, 3 und 4). Die Bewegung der Organe ist so aufeinander abgestimmt, daß der Förderzapfen 28 die Axialbewegung auch des Tragzapfens 15, 16 bestimmt durch Anlage aneinander infolge entsprechender Beaufschlagung des Tragzapfens 15, 16 mit Druckluft.The servomotor 68 is actuated by the (extending) support pin 15, 16. For this purpose, the servomotor 68 is connected via control lines 71 running in the axis of the conveyor pin 28 to an actuating element arranged in an axial bore 72, namely an electrical initiator 73. This switching element, which is known in construction and mode of operation, is provided by a metal piece 74 on the end face of the supporting pin 15, 16 acted upon when it is moved in the axial direction. The servomotor 68 is now switched on and in turn moves the feed pin 28 into the retracted position (to the left with respect to FIGS. 2, 3 and 4). The movement of the organs is coordinated with one another in such a way that the conveyor pin 28 also determines the axial movement of the support pin 15, 16 by abutment against one another as a result of corresponding exposure of the support pin 15, 16 to compressed air.

Die Bobine 11 erfährt während des Eintritts des Tragzapfens in die Mittenöffnung 42 keine Querverschiebung, sondern wird zwischen der Seitenführung 64 des Tragzapfens 15, 16 und einer ebenfalls tellerförmigen Gegenführung 75 am Förderarm 13 bewegungslos gehalten.The bobbin 11 does not undergo any transverse displacement when the trunnion enters the central opening 42, but is kept motionless between the side guide 64 of the trunnion 15, 16 and a likewise plate-shaped counter-guide 75 on the conveyor arm 13.

Die Übernahme der Bobinen 11 im Bereich der Übernahmestation 14 erfolgt in analoger Weise. Der Förderarm 13 wird bei zurückgezogenem Förderzapfen 28 an die zugekehrte Seite der Bobine 11 bewegt, wobei die tellerförmige Gegenführung 74 an der zugekehrten Seite der Bobine 11 anliegt. Der Förderzapfen 28 wird nunmehr durch Betätigen des Stellmotors 68 ausgefahren bis in die in Fig. 4 gezeigte Position.
