Vorrichtung zum Zwischenspeichern eines bandförmigen Mate¬ rialsDevice for temporarily storing a band-shaped material
Die Erfindung betrifft eine Vorrichtung zum Zwischenspeichern eines bandförmigen Materials.The invention relates to a device for temporarily storing a band-shaped material.
In der Technik gibt es viele Anwendungsgebiete, in denen bandförmige Materialien, aus Papier, Stoff, Metall oder Kunststoff zwischen verschiedenen Bearbeitungsschritten zwi¬ schengespeichert werden müssen. Hierzu werden in der Regel Rollen verwendet, auf die die bandförmigen Materialien auf- bzw. abgerollt werden können. Besteht nun die Notwendigkeit das bandförmige Material immer in derselben Richtung zu bear¬ beiten, so muß die Rolle zwischen jedem Bearbeitungsschritt umgespult werden, da sich der Anfang des bandförmigen Materi¬ als innen auf der Rolle befindet und somit von außen nicht zugänglich ist. Das jeweilige Umspulen zwischen den Bearbei- tungsschritten ist sehr zeitaufwendig.There are many fields of application in technology in which strip-like materials, made of paper, fabric, metal or plastic, have to be buffered between different processing steps. Rollers are usually used for this purpose, onto which the strip-shaped materials can be rolled up or unrolled. If there is now a need to always process the band-shaped material in the same direction, the roll must be rewound between each processing step, since the beginning of the band-shaped material is on the inside of the roll and is therefore not accessible from the outside. The rewinding between the processing steps is very time-consuming.
Zur Zwischenspeicherung eines bandförmigen Materials werden auch Tänzerwalzen verwendet, wodurch das bandförmige Material in der Reihenfolge der Eingabe weiterverarbeitet werden kann. Die Vorrichtung umfaßt im wesentlichen eine Reihe ortsfester, parallel zueinander angeordnete Walzen, unter denen eine Reihe beweglicher, parallel zueinander angeordnete Walzen angeordnet sind. Das bandförmige Material wird über eine er¬ ste Walze der ortsfesten Reihe zu einer ersten Walze der be- weglichen Reihe geführt und von dort über eine zweite Walze der oberen Reihe zurück zu einer zweiten Walze der unteren Reihe geführt und so weiter, bis das bandförmige Material über eine letzte Walze der oberen Reihe wieder abgeführt wird. Wird nur bandförmiges Material der ersten Walze der oberen Reihe zugeführt, aber kein bandförmiges Material an der letzten Walze der oberen Reihe abgeführt, so bewegen sich die Walzen der unteren Reihe gleichförmig nach unten, so daß dadurch das bandförmige Material zwischengespeichert wird. Wird an der letzten Walze der oberen Reihe das bandförmige Material schneller abgeführt als über die erste Walze der oberen Reihe zugeführt, so werden die Walzen der unteren Reihe durch die Zugkraft des bandförmigen Materials nach oben bewegt. Im quasi stationären Zustand, d.h. Zuführ- und Ab¬ führgeschwindigkeit sind gleich, verändert sich die Lage der Walzen der unteren Reihe nicht. Nachteilig an der bekannten Vorrichtung ist der große Platzbedarf bei nur beschränkter Speicherkapazität.Dancer rollers are also used for the intermediate storage of a band-shaped material, as a result of which the band-shaped material can be processed further in the order of input. The device essentially comprises a series of stationary rollers arranged parallel to one another, below which a series of movable rollers arranged parallel to one another are arranged. The strip-like material is guided over a first roller of the fixed row to a first roller of the movable row and from there is fed back over a second roller of the upper row to a second roller of the lower row and so on until the strip-like material is discharged again via a last roller of the upper row. If only strip material is fed to the first roller of the upper row, but no strip material is removed from the last roller of the upper row, the rollers of the lower row move downwards uniformly, so that thereby the band-shaped material is temporarily stored. If the strip-like material is discharged faster on the last roller of the upper row than is fed via the first roller of the upper row, the rollers of the lower row are moved upwards by the tensile force of the strip-like material. In the quasi-stationary state, ie the feed and discharge speeds are the same, the position of the rollers in the lower row does not change. The disadvantage of the known device is the large space requirement with only limited storage capacity.
Der Erfindung liegt die Aufgabe zugrunde, einen Zwischenspei¬ cher für bandförmiges Material zu schaffen, der einen gerin¬ gen Platzbedarf und große Speicherkapazität hat.The object of the invention is to create an intermediate store for strip-like material which requires little space and has a large storage capacity.
Die Lösung der Aufgabe ergibt sich durch die Merkmale des Patentanspruchs 1. Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.The object is achieved by the features of claim 1. Advantageous further developments of the invention result from the subclaims.
Durch die Anordnung eines drehbar gelagerten, hohlen äußeren Spulenkörpers, in welchem ein hohler innerer Spulenkörper ortsfest angeordnet ist, wobei der äußere Spulenkörper minde¬ stens eine zweite Durchlaßöffnung und der innere Spulenkörper mindestens eine zweite Durchlaßöffnung für das bandförmige Material haben, und der Anordnung einer Umlenkvorrichtung im Inneren des inneren Spulenkörpers, wobei das gegeneinander verschiebbare bandförmige Material bei Drehung des äußeren Spulenkörpers auf diesen und den inneren Spulenkörper auf- bzw. abgewickelt wird, wobei das bandförmige Material durch die Umlenkvorrichtung aus dem Inneren des inneren Spulenkör¬ pers herausgeführt wird, wird eine platzsparende Vorrichtung zum Zwischenspeichern eines bandförmigen Materials mit hoher Speicherkapazität geschaffen. Die Speicherkapazität der Vor¬ richtung wird nur vom Abstand des inneren Spulenkörpers zum äußeren Spulenkörper begrenzt. Durch die Beaufschlagung des äußeren Spulenkörpers mit einem konstanten Drehmoment wird gewährleistet, daß sich das band¬ förmige Material unabhängig von der Umfangsgeschwindigkeit gleichmäßig aufwickelt. Durch die Ausbildung des äußeren Spu¬ lenkörpers und/oder des inneren Spulenkörpers als Wellenkranz mit drehbaren Wellen, wird der Reibungswiderstand an den Oberflächen der jeweiligen Spulenkörper verringert, so daß das bandförmige Material keinen zu großen Zugkräften ausge¬ setzt ist.Due to the arrangement of a rotatably mounted, hollow outer coil body, in which a hollow inner coil body is arranged in a stationary manner, the outer coil body having at least one second passage opening and the inner coil body having at least one second passage opening for the strip-shaped material, and the arrangement of a deflection device in the interior of the inner bobbin, wherein the mutually displaceable band-shaped material is wound or unwound upon rotation of the outer bobbin on the latter and the inner bobbin, the band-shaped material being led out of the interior of the inner bobbin by the deflection device space-saving device for temporarily storing a band-shaped material with high storage capacity. The storage capacity of the device is only limited by the distance between the inner coil former and the outer coil former. By applying a constant torque to the outer coil former, it is ensured that the strip-shaped material is wound up uniformly regardless of the peripheral speed. By designing the outer coil body and / or the inner coil body as a shaft ring with rotatable shafts, the frictional resistance on the surfaces of the respective coil bodies is reduced, so that the band-shaped material is not exposed to excessive tensile forces.
Zur Reduzierung des Reibungswiderstandes kann die Oberfläche des äußeren und/oder inneren Spulenkörpers auch als Rollen¬ fläche ausgebildet sein, wobei die Rolle beweglich in einen die Oberfläche des Spulenkörpers bildenden Grundkörper einge- bracht oder zusammen auf einzelne Achsen angeordnet sind. Die gleichen Vorteile werden erzielt, wenn die Oberfläche aus Sintermaterial besteht und im Inneren der Spulenkörper ein Luftstrom radial nach außen durch das Sintermaterial hin¬ durch erzeugt wird. Dadurch schwebt das bandförmige Material auf einem Luftkissen. Durch die Anordnung eines Abzugsmotors im Inneren des inneren Spulenkörpers kann das bandförmige Material ohne Zugspannung umgelenkt werden.To reduce the frictional resistance, the surface of the outer and / or inner coil body can also be designed as a roller surface, the roller being movably inserted into a base body forming the surface of the coil body or arranged together on individual axes. The same advantages are achieved if the surface consists of sintered material and an air flow is generated radially outwards through the sintered material inside the coil former. This causes the band-shaped material to float on an air cushion. The strip-shaped material can be deflected without tension by the arrangement of a pull-off motor inside the inner coil body.
Die Erfindung wird nachfolgend anhand eines bevorzugten Aus- führungsbeispieles unter Bezugnahme auf die Zeichnungen näher erläutert. Es zeigen:The invention is explained in more detail below on the basis of a preferred exemplary embodiment with reference to the drawings. Show it:

Figur 3 eine Draufsicht auf die Vorrichtung zum Zwi¬ schenspeichern eines bandförmigen Materials In der Figur 1 ist eine Seitenansicht der Vorrichtung 10 zum Zwischenspeichern eines bandförmigen Materials 12 darge¬ stellt. In einem hohlen, äußeren Spulenkörper 14, der drehbar gelagert ist, ist konzentrisch ein hohler innerer Spulenkör¬ per 16 angeordnet, der durch ein festes Lager 18 ortsfest angeordnet ist. Der äußere Spulenkörper 14 und der innere Spulenkörper 16 werden durch radial angeordnete Wellen 20 gebildet, die drehbar gelagert und im äquidistanten Abstand zueinander angeordnet sind. Zwischen jeweils zwei benachbar¬ ten Wellen 20 bilden sich Durchlaßöffnungen 22, 24 im äußeren und inneren Spulenkörper 14, 16 zum Durchführen des bandför¬ migen Materials 12. Im Inneren des inneren Spulenkörpers 16 ist eine Umlenkeinrichtung 26 angeordnet, die durch zwei 90°- Umlenkungen 27 gebildet wird, um das bandförmige Material 12 aus dem Inneren des inneren Spulenkörpers 16 herauszuführen. Der äußere Spulenkörper 14 wird durch einen Antrieb 28 mit einem Antriebsriemen 30 mit einem konstanten Drehmoment be¬ aufschlagt. Das bandförmige Material 12 wird über einen durch Rollen gebildeten Eingang 32 in die Durchlaßöffnung 22 des äußeren Spulenkörpers 14 eingefädelt, durch die Durchlaßöff¬ nung 24 in das Innere des inneren Spulenkörpers 16 geführt, über die Umlenkeinrichtung 26 aus dem Inneren des inneren Spulenkörper 16 herausgeführt und einem durch Rollen reali- sierten Ausgang 34 zugeführt. Die Speicherkapazität der Vor¬ richtung 10 zum Zwischenspeichern eines bandförmigen Materi¬ als 12 wird nur durch den Abstand des inneren Spulenkörpers 16 zum äußeren Spulenkörper 14 begrenzt.Figure 3 is a plan view of the device for intermediate storage of a band-shaped material FIG. 1 shows a side view of the device 10 for temporarily storing a band-shaped material 12. In a hollow, outer bobbin 14, which is rotatably mounted, a hollow inner bobbin 16 is arranged concentrically, which is arranged in a fixed position by a fixed bearing 18. The outer coil body 14 and the inner coil body 16 are formed by radially arranged shafts 20 which are rotatably mounted and are arranged at an equidistant distance from one another. Between two adjacent shafts 20, passage openings 22, 24 are formed in the outer and inner bobbins 14, 16 for the passage of the band-shaped material 12. In the interior of the inner bobbin 16, a deflection device 26 is arranged, which by two 90 ° deflections 27 is formed to lead the band-shaped material 12 out of the interior of the inner bobbin 16. The outer coil body 14 is acted upon by a drive 28 with a drive belt 30 with a constant torque. The band-shaped material 12 is threaded through an inlet 32 formed by rollers into the passage opening 22 of the outer bobbin 14, passed through the passage opening 24 into the interior of the inner bobbin 16, led out of the interior of the inner bobbin 16 via the deflection device 26 and an output 34 realized by rolling. The storage capacity of the device 10 for temporarily storing a strip-shaped material 12 is only limited by the distance between the inner coil former 16 and the outer coil former 14.
Wird das bandförmige Material 12 am Eingang 32 und am Ausgang 34 angehalten, so stellt sich der dargestellte statische Zu¬ stand ein. Wird das bandförmige Material 12 am Ausgang 34 mit der gleichen Geschwindigkeit abgeführt wie es dem Eingang 32 zugeführt wird, so beaufschlagt die Zugspannung des bandför- migen Materials 12 den äußeren Spulenkörper 14 mit einem Drehmoment, das dem Drehmoment des Antriebs 28 entgegenwirkt, so daß der äußere Spulenkörper 14 in Ruhe bleibt. Wird das bandförmige Material 12 am Ausgang 34 angehalten, und am Ein¬ gang 32 freigegeben, so wird der äußere Spulenkörper 14 durch das Drehmoment des Antriebs 28 in Rotation versetzt, wodurch das bandförmige Material 12 auf den äußeren Spulenkörper 14 aufgewickelt wird. Ein Teil des bandförmigen Materials 12 wird dabei an der Welle 20 der Durchlaßöffnung 22 auf den inneren Spulenkörper umgelenkt und auf diesen aufgewickelt. Während der Rotation wird das bandförmige Material 12, das auf den inneren Spulenkörper 16 aufgewickelt wird, über die Durchlaßöffnung 22 vom äußeren Spulenkörper 14 nachgeliefert. Das bandförmige Material 12 auf dem äußeren Spulenkörper 14 und dem inneren Spulenkörper 16 verschiebt sich gegeneinan¬ der. Nach einer vollständigen Umdrehung des äußeren Spulen¬ körpers 14 ist der äußere Spulenkörper 14 und der innere Spu- lenkörper 16 vom bandförmigen Material 12 jeweils einmal vollständig umwickelt. Bei einer weiteren Umdrehung des äuße¬ ren Spulenkörpers 14 wird das bandförmige Material 12 von dem äußeren Spulenkörper 14 in der Länge des Umfanges des inneren Spulenkörpers 16 für den inneren Spulenkörper 16 gleitend nachgeliefert, so daß nach der vollständigen Umdrehung der äußere Spulenkörper 14 und der innere Spulenkörper 16 jeweils zweimal umwickelt sind, wobei das der Vorrichtung 10 zuerst zugeführte bandförmige Material 12 sich auf dem inneren Spu¬ lenkörper 16 befindet.If the strip-like material 12 is stopped at the inlet 32 and at the outlet 34, the static state shown is established. If the band-shaped material 12 is discharged at the outlet 34 at the same speed as it is fed to the inlet 32, the tensile stress of the band-shaped material 12 acts on the outer coil former 14 with a torque which counteracts the torque of the drive 28, so that the outer bobbin 14 remains at rest. Will that band-shaped material 12 stopped at the outlet 34 and released at the input 32, the outer coil former 14 is set in rotation by the torque of the drive 28, whereby the band-shaped material 12 is wound onto the outer coil former 14. A part of the band-shaped material 12 is deflected on the shaft 20 of the passage opening 22 onto the inner bobbin and wound thereon. During the rotation, the band-shaped material 12, which is wound onto the inner bobbin 16, is supplied from the outer bobbin 14 through the passage opening 22. The band-shaped material 12 on the outer bobbin 14 and the inner bobbin 16 moves against each other. After a complete revolution of the outer coil body 14, the outer coil body 14 and the inner coil body 16 are each completely wrapped once by the band-shaped material 12. With a further rotation of the outer coil body 14, the band-shaped material 12 is supplied by the outer coil body 14 along the length of the circumference of the inner coil body 16 for the inner coil body 16 so that after the complete rotation the outer coil body 14 and the inner one Coil bodies 16 are each wrapped twice, the band-shaped material 12 fed to the device 10 first being located on the inner coil body 16.
In Figur 2 ist eine Seitenansicht der Vorrichtung 10 zum Zwi¬ schenspeichern des bandförmigen Materials 12 mit freigegebe¬ nem Eingang 32 und Ausgang 34 dargestellt. Durch das Drehmo¬ ment des Antriebs 28 wird das bandförmige Material 12 vom Eingang 32 im Uhrzeigersinn 36 auf die oberste Lage des be¬ reits auf dem äußeren Spulenkörper 14 aufgewickelten bandför¬ migen Materials 12 aufgewickelt. Gleichzeitig wird ein Teil des sich direkt auf der Oberfläche des äußeren Spulenkörpers 14 befindlichen bandförmigen Materials 12 im Uhrzeigersinn 36 abgewickelt, durch die Durchlaßöffnung 22 in das Innere des äußeren Spulenkörpers 14 geführt und im Gegenuhrzeigersinn 38 auf die oberste Lage des sich auf dem inneren Spulenkörper 16 befindlichen bandförmigen Materials 12 aufgewickelt. Durch einen nicht dargestellten Abzugsmotor wird eine Zugkraft auf das bandförmige Material 12 am Ausgang 34 ausgeübt, so daß das direkt auf der Oberfläche des inneren Spulenkörpers 16 befindliche bandförmige Material 12 im Gegenuhrzeigersinn 38 abgewickelt wird und über die 90°-Umlenkungen 27 der Umlenk¬ einrichtung 26 zuerst aus dem Inneren des inneren Spulenkör¬ pers 16 in Figur 2 senkrecht zur Papierebene herausgeführt und anschließend in einer Ebene parallel zur Papierebene in Figur 2 zum Eingang 32 umgelenkt wird.FIG. 2 shows a side view of the device 10 for the intermediate storage of the strip-shaped material 12 with the input 32 and the output 34 released. Due to the torque of the drive 28, the band-shaped material 12 is wound from the inlet 32 clockwise 36 onto the uppermost layer of the band-shaped material 12 already wound on the outer spool 14. At the same time, part of the strip-shaped material 12 located directly on the surface of the outer coil former 14 is unwound in a clockwise direction 36, passed through the passage opening 22 into the interior of the outer coil former 14 and counterclockwise 38 to the uppermost layer of the layer on the inner coil former 16 located band-shaped material 12 wound. A pulling motor (not shown) exerts a tensile force on the band-shaped material 12 at the outlet 34, so that the band-shaped material 12 located directly on the surface of the inner bobbin 16 is unwound in the counterclockwise direction 38 and via the 90 ° deflections 27 of the deflection device 26 is first led out of the interior of the inner bobbin 16 in FIG. 2 perpendicular to the paper plane and then deflected in a plane parallel to the paper plane in FIG. 2 to the entrance 32.
In Figur 3 ist eine Draufsicht auf die Vorrichtung 10 darge¬ stellt. Mittels der ersten 90°-Umlenkung 27 wird das bandför¬ mige Material 12 aus dem Inneren des inneren Spulenkörpers 16 senkrecht herausgeführt und durch die zweite Umlenkung 27 in eine zur Ebene des zugeführten bandförmigen Materials 12 am Eingang 32 parallele Ebene umgelenkt.FIG. 3 shows a top view of the device 10. By means of the first 90 ° deflection 27, the band-shaped material 12 is led vertically out of the interior of the inner coil former 16 and deflected by the second deflection 27 into a plane parallel to the plane of the supplied band-shaped material 12 at the entrance 32.
Ein bevorzugtes Anwendungsgebiet der Erfindung ist die Drucktechnik. Durch Anordnung der Vorrichtung 10 zwischen einem Drucker und einer Papiernachbearbeitungsvorrichtung bzw. einer Papiervorbearbeitungsvorrichtung kann die Leistungsfähigkeit eines einen Drucker enthaltenden Gesamtsystems erhöht werden. Ein Anhalten eines Teilsystems, z.B. des Druckers, muß nicht zwangsläufig zu einem Anhalten des Gesamtsystems führen. Dadurch erhöht sich der Gesamtdurchsatz im Gesamtsystem und damit dessen Leistungsfähigkeit. Generell läßt sich durch die Erfindung die Leistungsfähigkeit eines solchen Gesamtsystems, das nicht im gleichen Zeittakt eine Endlosbahn bearbeitende Teilsysteme enthält, dadurch erhöhen, daß zwischen den Teilsystemen ein gemäß der Erfindung realisierter "First-in-First-out-Puffer" geschaltet wird. A preferred field of application of the invention is printing technology. By arranging the device 10 between a printer and a paper post-processing device or a paper pre-processing device, the performance of an overall system containing a printer can be increased. Stopping a subsystem, e.g. of the printer, does not necessarily have to lead to a stop of the entire system. This increases the overall throughput in the overall system and thus its performance. In general, the performance of such an overall system, which does not contain subsystems processing an endless web at the same time cycle, can be increased by the invention in that a "first-in-first-out buffer" implemented according to the invention is connected between the subsystems.
