Abstract
Description
Die Erfindung betrifft einen horizontalen Bandspeicher, insbesondere für Blechbänder, umfassend einen auf einem Gestell in variablem Abstand zu einer ortsfesten Bandumlenkrolle verfahrbaren Schlingenwagen mit wenigstens einer Umlenkrolle für eine längenveränderliche Band-Vorratsschlaufe und mehreren Stützwagen mit Stützrollen zwischen Bandumlenkrolle und Schlingenwagen, sowie ein endlos um Umlenkrollen geführtes, mit dem Schlingenwagen verbundenes flexibles Antriebselement, das mit einem Antriebsrad jedes Stützwagens zusammenwirkend geführt und von dem der Fahrantrieb eines jeden Stützwagens relativ zum Fahrweg des Schlingenwagens abgeleitet ist.The invention relates to a horizontal tape store, especially for metal strips, comprising one on one Frame at a variable distance from a fixed Belt guide roller movable sling carriage with at least a pulley for a variable length Belt storage loop and several support carriages with support rollers between belt guide roller and sling wagon, as well as an endless guided around pulleys and connected to the sling carriage flexible drive element that each with a drive wheel Support car guided interactively and of which the Travel drive of each support carriage relative to the travel path of the Loop car is derived.
Bekanntlich sind Bandspeicher erforderlich, um Walzgerüste in Walzwerken kontinuierlich betreiben zu können, und zwar auch dann, wenn Bandmaterial von Einzelbunden, die vor Einführung in das Walzgerüst miteinander verbunden werden müssen, dem Walzwerk oder Walzgerüst endlos zugeführt und von diesem gewalzt werden soll. Um bei diesem Vorgang eine zeitweilige Verlangsamung der Walzgeschwindigkeit oder gar ein Anhalten der Walzgerüste zu vermeiden, muß ein Bandspeicher, beispielsweise in Form eines Schlingenspeichers oder Schlingenbildners, vorgesehen werden, der in seiner Kapazität derart ausgelegt ist, daß das Band auch dann dem Walzgerüst bzw. Walzwerk kontinuierlich zugeführt werden kann, wenn die einzelnen Bunde vorbereitet bzw. miteinander verschweißt werden müssen.As is well known, strip stores are required to roll stands in To be able to operate rolling mills continuously, and indeed then, if tape material from individual bundles, before the introduction must be connected to each other in the rolling stand Rolling mill or rolling mill fed endlessly and by this should be rolled. To be a temporary in this process Slowing down the rolling speed or even stopping to avoid the rolling stands, a strip store must for example in the form of a loop storage or Looper, provided in its capacity is designed in such a way that the strip then also passes through the roll stand or rolling mill can be fed continuously if the individual bundles prepared or welded together Need to become.
Gleiche Überlegungen treffen auch für andere Metallbänder verarbeitende Anlagenteile zu, wie beispielsweise für Beizanlagen oder Glühöfen, die kontinuierlich betrieben werden und bei denen unterschiedlich einlaufende Bandgeschwindigkeiten ausgeglichen werden müssen. Zum Einsatz kommen je nach Platzverhältnissen Schlingentürme, Schlingengruben oder horizontal liegende, vielfach als sogenannte Schlingenzieher bezeichnete Bandspeicher.The same considerations apply to other metal strips processing plant parts, such as for Pickling plants or annealing furnaces that are operated continuously and where different incoming Belt speeds must be balanced. For use Depending on the space available, loop towers come Loop pits or horizontal ones, often called so-called loop puller called tape storage.
Horizontale Bandspeicher sind im allgemeinen dadurch gekennzeichnet, daß sie einen gegen die Zugkraft des Bandes mit Rückstellkraft beweglich gehaltenen Schlingenwagen und dazwischen mehrere Stützwagen mit Stützrollen aufweisen, die ebenfalls beweglich gelagert sind. Die Rückstellkraft wird über Seile von einer mit Konstantantrieb angetriebenen Seilwinde erzeugt.Horizontal tape stores are generally characterized by this characterized that they have one against the tensile force of the tape sling carriage and movable with restoring force in between have several support cars with support rollers that are also movably mounted. The restoring force will over ropes from a driven with constant drive Winch generated.
Aus der DE-OS 1 953 169 ist ein horizontaler Bandspeicher für Bandverarbeitungsanlagen mit Tragrollen zwischen Schlingenwagen und Zuleit- bzw. Ableitrollen bekannt, bei welchem die Trag rollen in einem oder mehreren in Horizontalrichtung beweglichen, sogenannten Nachläufern gelagert sind. Zwischen dem Schlingenwagen und jedem nächstliegenden Nachläufer ist an diesen eine angetriebene Seiltrommel angeordnet, welche ein zugeordnetes Verbindungsseil anspannt. Am Schlingenwagen ist eine endlose Kette mit Mitnehmern für die einzelnen Nachläufer befestigt. From DE-OS 1 953 169 is a horizontal tape storage for Strip processing plants with idlers between Loop car and supply or discharge rollers known, at which the support roll in one or more in Horizontal direction movable, so-called followers are stored. Between the sling car and everyone the closest follower is a driven one Rope drum arranged, which is an associated Connection rope tense. There is an endless loop car Chain with carriers attached for the individual followers.
Weil bei dieser Anordnung der Schlingenwagen bei seinem Verfahren im Sinne einer Verkürzung der Vorratsschlinge die Nachläufer vor sich herschiebt, kommt der Rückstellkraft über die Seiltrommelantriebe lediglich die Aufgabe zu, die Verbindungsseile gespannt zu halten, so daß die jeweils folgenden Nachläufer erst durch den Schlingenwagen bewegt werden, wenn die Seillängen zwischen diesem und dem jeweils folgenden Nachläufer aufgebraucht sind.Because with this arrangement, the sling wagon with his Process in the sense of shortening the supply loop Pushes the follower in front of it, the restoring force comes over the cable drum drives only the task to To keep connecting cables taut so that each following trailer only moved by the sling car if the rope lengths between this and each following followers are used up.
Diese Ausbildung ist nicht in der Lage, einen stoßfreien Betrieb der Nachläuferwagen sicherzustellen, und weiterhin ergibt die Ausbildung jedes Nachläufers mit einer angetriebenen Seilwinde einen hohen technischen Aufwand, wobei für jeden Nachläufer ein eigener Drehmomentmotor mit Stromeinspeisung über eine Schleifleitung oder eine Kabelgirlande vorgesehen werden muß. Die Schleifleitung ist als Gefahrenquelle äußerst nachteilig, und eine Kabelgirlande mit ihren erforderlichen Führungselementen schränkt die Zugänglichkeit zum Bandspeicher stark ein. Im übrigen ist die bekannte Ausführung mit zugehöriger Steuerung sehr kostenintensiv.This training is unable to provide a bumpless Ensure operation of the trailer car, and continue results in the formation of each successor with one driven winch a high technical effort, being a separate torque motor for each follower Power supply via a conductor line or a Cable garland must be provided. The conductor rail is extremely disadvantageous as a source of danger, and a cable garland with its necessary guide elements limits the Accessibility to the tape storage strongly. Otherwise, the well-known version with associated control very expensive.
Aus der EP-0 110 864 B1 ist ein horizontaler Bandspeicher bekannt, der ebenfalls einen verfahrbaren Schlingenwagen aufweist, an welchen einzelne Stützwagen mit Hilfe von flexiblen, gegen Rückstellkraft ausziehbaren Zuggliedern angekoppelt sind. Diese Zugglieder sollen zumindest bereichsweise elastisch dehnbar und beispielsweise als Gummiseile oder dergleichen ausgebildet und schlingenbildend um Umlenkrollen geführt sein. Diese Ausbildung soll einen stoßfreien Antrieb der Stützwagen vom Schlingenwagen her unter Wahrung eines gleichmäßigen Abstandes der einzelnen Stützwagen voneinander sicherstellen.EP-0 110 864 B1 is a horizontal tape store known who also has a movable sling car on which individual support car with the help of flexible tension members that can be pulled out against restoring force are coupled. These tension members should at least stretchable in some areas and, for example, as Rubber ropes or the like formed and looping be guided around pulleys. This training should smooth drive of the support car from the sling car Maintaining an even distance between the individual support cars ensure from each other.
Von Nachteil ist dabei, daß die flexiblen bzw. elastischen Gummiseile relativ schnell altern und spröde werden und deshalb unkontrolliert schnell verschleißen bzw. reißen können, insbesondere bei Einwirkung von Strahlungswärme. Auch können Gummiseile in der rauhen Walzwerksumgebung leicht verletzt werden, so daß die Gefahr eines schnellen Einreißens oder Bruch der Gummiseile zu befürchten ist.The disadvantage here is that the flexible or elastic Rubber ropes age relatively quickly and become brittle and therefore wear out or tear quickly in an uncontrolled manner can, especially when exposed to radiant heat. Also can easily find rubber ropes in the harsh rolling mill environment be injured, so the risk of rapid tearing or breakage of the rubber cables is to be feared.
Die EP 0 388 708 B1 zeigt einen horizontalen Bandspeicher mit einem verfahrbaren Schlingenwagen, an welchen einzelne Stützwagen mittels eines Seils, einer Kurventrommel und eines Drehmomentmotors angekoppelt sind. Über jede der Kurventrommeln wird der jeweilige Abstand zwischen den Stützwagen erzeugt, wobei ein gleichmäßiges Drehmoment des Motors die Seilverbindungen unter Spannung hält. Nachteilig ist ähnlich der vorgenannten DE-OS 1 953 169 bei diesem Bandspeicher, daß für jeden Stützwagen ein eigener Drehmomentmotor angeordnet und die Stromeinspeisung ebenfalls über eine Schleifleitung oder eine Kabelgirlande vorgesehen sein muß. Hierfür gelten weiterhin die vorgenannten Nachteile.EP 0 388 708 B1 shows a horizontal tape store a movable loop carriage, on which individual Support car using a rope, a cam drum and one Torque motor are coupled. About each of the Curve drums are the respective distance between the Support car generated, with a uniform torque of Motors keeps the cable connections under tension. Disadvantageous is similar to the aforementioned DE-OS 1 953 169 in this Tape storage that for each support car its own Torque motor arranged and the power supply also provided via a conductor rail or a cable garland have to be. The aforementioned disadvantages still apply to this.
Aus der AT-PS 299 103 ist ein horizontaler Bandspeicher für Blechbänder mit einem verfahrbaren und vorzugsweise mit konstantem Antriebsmoment im Sinne einer Schlaufenvergrößerung antreibbaren Schlingenwagen und mehreren Stützwagen bekannt, die entlang von Führungsschienen bewegbar sind. Ein endloses, um Umlenkrollen geführtes Seil ist mit dem Schlingenwagen und den Stützwagen verbunden. Von diesem Seil wird über Abnehmerrollen unter Zwischenschaltung von Untersetzungsgetrieben der Antrieb für die Stützwagen abgeleitet, in der Weise, daß bei einer Bewegung des Schlingenwagens die Stützwagen untereinander einen gleichen Abstand aufweisen.From AT-PS 299 103 is a horizontal tape storage for Sheet metal strips with a movable and preferably with constant drive torque in the sense of an enlarged loop drivable loop car and several support cars known which are movable along guide rails. An endless Rope is guided around the pulleys with the sling carriage and connected the support car. This rope is about Customer roles with the interposition of Reduction gear drive for the support car derived in such a way that when the Sling car the support carts are the same among themselves Distance.
Bei längerem Betrieb des Bandspeichers kann es nun vorkommen, daß ein Schlupf zwischen dem als Antriebselement verwendeten Seil und den Abnehmerrollen an den Stützwagen auftritt. Dieser Schlupf hat dann zur Folge, daß sich die Abstände zwischen den Stützwagen ändern und untereinander nicht mehr gleich sind. Fallweise führt dies dazu, daß bei einer ungleichen Stellung einzelner Stützwagen diese aufeinanderstoßen bzw. gegen Anschläge fahren oder mit dem Schlingenwagen stoßartig kontaktiert werden. Um dies zu vermeiden, ist jeder Stützwagen mit einer in beiden Richtungen wirkenden, mit einem Hebelgestänge ausgebildeten Rutschkupplung versehen. Nachteilig ist hierbei der erforderliche kinematische Aufwand sowie eine infolge Störanfälligkeit erforderliche öftere Wartung, die dennoch einen wirklich stoßfreien Betrieb nicht garantieren kann.If the tape storage is operated for a long time, that a slip between that used as the drive element Rope and the customer rollers on the support carriage occurs. This Slip then has the consequence that the distances between the Change support car and are no longer the same among each other. In some cases this leads to an unequal position single support car these collide or against each other Driving stops or jerky with the sling car be contacted. To avoid this, every support car is with one acting in both directions, with one Provide lever linkage designed slip clutch. The disadvantage here is the kinematic effort required as well as a frequent need due to susceptibility to faults Maintenance that does not really mean a smooth operation can guarantee.
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, unter Vermeidung der vorstehend erörterten Nachteile und Schwierigkeiten einen horizontalen Bandspeicher anzugeben, bei welchem die Verbindungen zwischen den Stützwagen und dem Schlingenwagen für einen störungsfreien und bevorzugt wartungsfreien Betrieb in einfacher Weise ausgebildet sind und die es ermöglichen daß beim Verfahren des Schlingenwagens im Sinne einer Schlingenveränderung die Abstände der Stützwagen stoßfrei veränderlich und untereinander gleichbleibend sind, so daß Voraussetzungen für eine optimale Führung des Bandes auf den Stützrollen der Stützwagen gegeben sind. Based on this prior art, the invention lies Task based, avoiding the ones discussed above Disadvantages and difficulties of a horizontal tape storage indicate the connection between the Support carriage and the sling carriage for a trouble-free and prefers maintenance-free operation in a simple manner are trained and that make it possible in the process of the sling car in the sense of a sling change The spacing of the support carriages can be changed smoothly and are constant with each other, so that conditions for optimal guidance of the belt on the support rollers of the Support cars are given.
Zur Lösung der Aufgabe wird bei einem Bandspeicher der im Oberbegriff von Anspruch 1 genannten Art mit der Erfindung vorgeschlagen,
- daß im Bereich des Verfahrensweges der Stützwagen ein zweites flexibles Antriebselement entlang des Gestelles aufgespannt und über ein unteres mit dem Antriebselement zusammenwirkendes Antriebsrad eines jeden Stützwagens geführt ist, und
- daß das erste Antriebsrad mit dem zweiten Antriebsrad durch ein Getriebe kinematisch verbunden ist.
- that a second flexible drive element is clamped along the frame in the region of the process path of the support carriage and is guided over a lower drive wheel of each support carriage interacting with the drive element, and
- that the first drive wheel is kinematically connected to the second drive wheel by a gear.
Mit großem Vorteil ersetzt das untere Antriebselement die beim Stand der Technik vielfach verwendeten motorgetriebenen Seilwinden an den Stützwagen und sorgt selbsttätig für die Ausbildung gleichmäßiger Abstände beim Ein- und Ausfahren des Schlingenwagens bzw. der Vorratsschlaufen.The lower drive element replaces that of the State of the art motor-driven, widely used Winches on the support car and take care of that automatically Training of uniform distances when retracting and extending the Sling car or the storage loops.
Dies wird in unkomplizierter Weise und mit großem Vorteil dadurch erreicht, daß bei einer Fahrbewegung des Schlingenwagens gemeinsam mit dem an ihm befestigten oberen Antriebselement das von diesem umschlungene obere Antriebsrad jedes Stützwagens in Drehbewegung angetrieben wird. Infolge der Getriebeverbindung zwischen dem oberen Antriebsrad und dem unteren Antriebsrad wird letzteres im Verhältnis der Getriebeuntersetzung anteilmäßig mit angetrieben. Weil jedoch das untere Antriebselement ortsfest aufgespannt ist, wird durch das damit zwangsweise im Eingriff befindliche untere Antriebsrad der Stützwagen zu einer relativen Fahrbewegung im Verhältnis der Fahrstrecke des Schlingenwagens zur Fahrstrecke des Stützwagens bewegt, indem das untere Antriebsrad am unteren Antriebselement abrollt.This is done in a straightforward manner and with great advantage thereby achieved that when the vehicle moves Sling carriage together with the upper one attached to it Drive element the upper drive wheel wrapped by this each support carriage is driven in rotation. As a result the gear connection between the upper drive wheel and the lower drive wheel is the latter in relation to the Gear reduction partly driven. Because, however the lower drive element is clamped stationary by the lower one that is inevitably engaged Drive wheel of the support car to a relative movement in the Ratio of the route of the sling car to the route of the support carriage moved by the lower drive wheel on rolls lower drive element.
Die Getriebeübersetzungen der einzelnen Stützwagen sind so gewählt, daß der jeweilige Abstand zwischen dem Schlingenwagen und der ortsfesten Bandumlenkrolle in immer gleiche Abstände aufgeteilt wird.The gear ratios of the individual support cars are like this chosen that the respective distance between the sling car and the stationary belt deflection roller always at the same intervals is divided.
Eine Ausgestaltung sieht vor, daß die flexiblen Antriebselemente ein Keilriemen, eine Zahnkette, eine Rollenkette, eine Gliederkette oder ein Zahnriemen sind. Dabei ist mit großem Vorteil bevorzugt von der Maßnahme Gebrauch gemacht, daß die Antriebselemente Zahnriemen und die mit diesem zusammenwirkenden Antriebsräder als Zahnritzel ausgebildet sind. Auf diese Weise wird ein sicherer, geräuscharmer und schlupffreier Betrieb des Bandspeichers erreicht.One embodiment provides that the flexible Drive elements a V-belt, a tooth chain, a Roller chain, a link chain or a toothed belt. Here is of great advantage to use the measure made that the drive elements toothed belt and with this interacting drive wheels as a pinion are trained. This way, a safe, Quiet and slip-free operation of the tape storage reached.
Die Vorteile des erfindungsgemäßen Bandspeichers sind weiterhin darin zu sehen, daß sowohl beim Füllen als auch beim Entleeren des Speichers das Blechband von den Tragrollen der Stützwagen im jeweils gleichmäßigen Abständen getragen wird, daß keine stoßartige Belastung beim Verfahren des Schlingenwagens auf die Stützwagen übertragen wird, und daß durch den Einsatz der Zahnriemen und der Getriebe ein einfaches, kostengünstiges und zuverlässiges System ausgebildet wird.The advantages of the tape store according to the invention are continue to be seen in the fact that both when filling and when Empty the storage of the metal strip from the idlers of the Support car is carried at regular intervals, that no sudden load in the process of Loop car is transferred to the support car, and that through the use of timing belts and gears simple, inexpensive and reliable system is trained.
