Description

Die Erfindung bezieht sich auf einen Bandspeicher, insbesondere für Blechbänder, bestehend aus einem verfahrbaren Schlaufenwagen mit wenigstens einer Umlenkrolle für eine Vorratsschlaufe des Bandes und aus Stützwagen, die Tragrollen für das wenigstens eine obere Schlaufentrum aufweisen und miteinander und mit dem Schlaufenwagen durch flexible, gegen eine Rückstellkraft ausziehbare Zugglieder verbunden sind.The invention relates to a band storage device, in particular for sheet metal strips, consisting of a movable loop carriage with at least one deflection roller for a supply loop of the band and of support carriages which have support rollers for the at least one upper loop center and with each other and with the loop carriage through flexible, against one Retractable pull-out tension members are connected.

Bei üblichen Bandspeichern dieser Art werden die Zugglieder aus Ketten oder Seilen gebildet, so daß beim Verfahren des Schlaufenwagens im Sinne einer Schlaufenbildung die einzelnen Stützwagen nacheinander vom Schlaufenwagen mitgezogen werden, wenn sich die Ketten oder Seile zwischen dem Stützwagen und dem Schlaufenwagen spannen. Die beim Spannen der Zugglieder auftretenden hohen Beschleunigungen der Stützwagen ergeben beim Anfahren jedes einzelnen Stützwagens stoßartige Belastungen, die tunlichst vermieden werden sollen. Außerdem wird das Band im Bereich des oberen Schlaufentrums ungleichmäßig unterstützt, weil der Abstand zwischen zwei benachbarten Stützwagen entweder durch die gespannte Kette oder durch die aneinandergeschobenen Stützwagen bestimmt wird.In conventional belt stores of this type, the tension members are formed from chains or ropes, so that when the loop carriage is moved in the sense of a loop formation, the individual support carriages are pulled along by the loop carriage when the chains or ropes stretch between the support carriage and the loop carriage. The high accelerations of the support carriages that occur when tensioning the tension members result in shock-like loads when starting each support carriage, which should be avoided as far as possible. In addition, the band is supported unevenly in the area of the upper loop center because the distance between two adjacent support cars is determined either by the tensioned chain or by the support cars pushed together.

Diese Nachteile treten grundsätzlich auch bei einem bekannten Bandspeicher auf (DE-A-1 953169), bei dem die die Stützwagen verbindenden Seile auf Seiltrommeln aufgewickelt und durch den Antrieb der Seiltrommeln konstant gespannt gehalten werden. Da der Schlaufenwagen bei seinem Verfahren im Sinne einer Verkürzung der Vorratsschlaufe die Stützwagen vor sich herschiebt, kommt der Rückstellkraft über die Seiltrommelantriebe lediglich die Aufgabe zu, die Verbindungsseile gespannt zu halten, so daß die jeweils folgenden Stützwagen erst durch den Schlaufenwagen bewegt werden können, wenn die Seillängen zwischen dem Schlaufenwagen und den jeweils folgenden Stützwagen aufgebraucht sind.These disadvantages basically also occur in a known band storage device (DE-A-1 953169), in which the cables connecting the support carriages are wound on cable drums and are kept constantly tensioned by the drive of the cable drums. Since the loop carriage pushes the support carriage in front of it in the sense of shortening the supply loop, the restoring force via the cable drum drives only has the task of keeping the connecting cables taut so that the following support carriage can only be moved by the loop carriage if the rope lengths between the loop car and the following support car are used up.

Um stoßartige Belastungen zu vermeiden, ist es schließlich bekannt (AT-B-299103), die Stützwagen über ein endlos um Umlenkrollen geführtes, sich über die maximale Schlaufenlänge erstreckendes Zugseil anzutreiben, das mit dem Schlaufenwagen fest verbunden ist und das mit dem Stützwagen unter Zwischenschaltung von Untersetzungsgetrieben in Antriebsverbindung steht, so daß die Stützwagen mit einer vom Schlaufenwagen weg schrittweise abnehmenden Geschwindigkeit angetrieben werden, die eine gleichmäßige Aufteilung der Stützwagen auf die jeweilige Schlaufenlänge sicherstellt. Damit können zwar die bei einer Kettenverbindung zwischen dem Stützwagen und dem Schlaufenwagen auftretenden Stoßbelastungen vermieden werden, doch wird dieser Vorteil mit einem vergleichsweise großen Aufwand erkauft.Finally, in order to avoid shock-like loads, it is known (AT-B-299103) to drive the support carriages via a traction cable which is endlessly guided around deflection pulleys and extends over the maximum loop length and which is firmly connected to the loop carriage and to the support carriage with interposition of reduction gears is in drive connection, so that the support carriages are driven at a gradually decreasing speed away from the loop carriage, which ensures a uniform division of the support carriages over the respective loop length. Although the shock loads occurring in the case of a chain connection between the support carriage and the loop carriage can be avoided, this advantage is purchased with a comparatively great outlay.

Der Erfindung liegt somit die Aufgabe zugrunde, diesen Aufwand zu vermeiden, so daß auch beim Antrieb der Stützwagen über flexible Zugglieder ein stoßfreier Antrieb der Stützwagen vom Schlaufenwagen her sichergestellt werden kann, und zwar unter Wahrung eines gleichmäßigen Abstandes der einzelnen Stützwagen voneinander.The invention is therefore based on the object to avoid this effort, so that even when driving the support car via flexible tension members, a bumpless drive of the support car can be ensured from the loop car, while maintaining a uniform distance between the individual support cars.

Die Erfindung löst die gestellte Aufgabe dadurch, daß die Zugglieder zumindest bereichsweise elastisch dehnbar, beispielsweise als Gummiseile od. dgl., ausgebildet und vorzugsweise schlingenbildend um Umlenkrollen geführt sind.The invention achieves the stated object in that the tension members are at least partially elastically extensible, for example as rubber ropes or the like, and are preferably looped around deflection rollers.

Die elastische Dehnbarkeit der Zugglieder ermöglicht unter Wahrung der Antriebsverbindung eine Abstandsvergrößerung der Stützwagen voneinander, wobei die Vorspannung der Zugglieder selbstverständlich größer als der Fahrwiderstand der Stützwagen sein muß, um das gleichzeitige Verfahren aller Stützwagen unabhängig von der Länge der Vorratsschlaufe sicherzustellen. Damit bei entsprechenden Rückstellkräften ausreichende Dehnungslängen sichergestellt werden können, muß der dehnbare Bereich der Zugglieder entsprechend lang sein. Um die Länge der dehnbaren Zugglieder nicht vom kürzesten Abstand der Stützwagen voneinander abhängig zu machen, kann jedes Zugglied vorteilhaft schlingenbildend um Umlenkrollen geführt werden, so daß auch wesentlich größere Dehnungslängen sichergestellt sind. Die Dehnungslänge der einzelnen Zugglieder entspricht dabei nur einem Bruchteil der Fahrstrecke des Schlaufenwagens, weil ja alle Zugglieder gleichermaßen belastet werden und sich bei gleichen Rückstellkräften gleich dehnen.The elastic extensibility of the tension members allows an increase in the distance between the support cars while maintaining the drive connection, the tension of the tension members must of course be greater than the running resistance of the support cars to ensure the simultaneous movement of all support cars regardless of the length of the supply loop. The stretchable area of the tension members must be correspondingly long so that adequate extension lengths can be ensured with appropriate restoring forces. In order not to make the length of the stretchable tension members dependent on the shortest distance between the support carriages, each tension member can advantageously be looped around deflection pulleys, so that much greater elongation lengths are ensured. The elongation length of the individual tension members corresponds to only a fraction of the travel distance of the loop carriage because all tension members are loaded equally and stretch the same way with the same restoring forces.

Üblicherweise sind die Stützwagen auf beiden Längsseiten miteinander durch Zugglieder verbunden. Eine solche Verbindung hat jedoch den Nachteil, daß beim Reißen eines Zuggliedes auf der einen Längsseite die Gefahr besteht, daß sich die betroffenen Stützwagen wegen der dann einseitigen Belastung querstellen. Um dies zu vermeiden, können die Zugglieder mit ihren beiden Enden an einem Stützwagen angreifen und um wenigstens eine Umlenkrolle am benachbarten Stützwagen geführt sein. Diese Konstruktion gewährleistet darüber hinaus stets gleiche Zugspannungen auf beiden Längsseiten der Stützwagen. Außerdem wird eine größere Dehnungslänge ohne zusätzliche Schlingenbildung sichergestellt.The support carriages are usually connected to one another on both long sides by tension members. However, such a connection has the disadvantage that if a tension member is torn on one long side, there is a risk that the support carriages concerned will cross because of the then one-sided load. To avoid this, the tension members can engage with their two ends on a support carriage and be guided around at least one deflection roller on the adjacent support carriage. In addition, this design always ensures the same tensile stresses on both long sides of the support car. In addition, a greater stretch length is ensured without additional loop formation.

Damit der Bandspeicher in einfacher Weise an die jeweiligen Fahrverhältnisse angepaßt werden kann, kann die Vorspannung der elastisch dehnbaren Zugglieder einstellbar sein, so daß die Rückstellkraft für die Zugglieder mit Sicherheit größer als der Fahrwiderstand des Stützwagenzuges ist. Die Einstellung der Vorspannung kann dabei in einfacher Weise über eine Spanneinrichtung für die dehnbaren Zugglieder erfolgen.So that the tape storage can be easily adapted to the prevailing driving conditions, the pretension of the elastically stretchable tension members can be adjustable, so that the restoring force for the tension members is certainly greater than the driving resistance of the support car train. The preload can be adjusted in a simple manner via a tensioning device for the stretchable tension members.

In der Zeichnung ist der Erfindungsgegenstand beispielsweise dargestellt. Es zeigen

  • Figur 1 den Bandspeicher in einer schematischen Seitenansicht,
  • Figur 2 diesen Bandspeicher in Draufsicht und
  • Figur 3 eine Konstruktionsvariante der Verbindung zweier Stützwagen in Draufsicht auf die Stützwagen in einem größeren Maßstab.
The subject matter of the invention is shown in the drawing, for example. Show it
  • FIG. 1 shows the tape store in a schematic side view,
  • Figure 2 shows this tape storage in plan view and
  • Figure 3 shows a design variant of the connection of two support cars in plan view of the support car on a larger scale.

Wie insbesondere die Fig. 1 und 2 zeigen, besteht der dargestellte Bandspeicher im wesentlichen aus einem Schlaufenwagen 1 und mit Hilfe des Schlaufenwagens 1 verziehbaren Stützwagen 2, die mit dem Schlaufenwagen 1 auf Schienen 3 geführt sind. Die Stützwagen 2 weisen dabei Tragrollen 4 für das jeweils obere Trum 5 zweier Vorratsschlaufen 6 auf, die um je eine Umlenkrolle 7 des Schlaufenwagens 1 geführt sind. Während das untere Trum 8 der äußeren Vorratsschlaufe auf ortsfesten Rollen 9 im Bereich der die Schienen 3 tragenden Fahrbahn 10 abgestützt ist, ruht das untere Trum 11 der inneren der beiden Vorratsschlaufen 6 auf Stützrollen 12 der Stützwagen 2 auf.As shown in particular in FIGS. 1 and 2, the tape store shown consists essentially of a loop carriage 1 and support carriage 2 which can be moved with the aid of the loop carriage 1 and which are guided on rails 3 with the loop carriage 1. The support carriages 2 have support rollers 4 for the respective upper run 5 of two storage loops 6, which are each guided around a deflection roller 7 of the loop carriage 1. While the lower run 8 of the outer supply loop is supported on stationary rollers 9 in the region of the carriageway 10 carrying the rails 3, the lower run 11 of the inner of the two supply loops 6 rests on support rollers 12 of the support carriage 2.

Die einzelnen Stützwagen 2 sind miteinander durch Zugglieder 13 verbunden, wobei die Verbindung des dem Schlaufenwagen 1 unmittelbar benachbarten Stützwagens 2 mit dem Schlaufenwagen 1 und des einer ortsfesten Ablaufstelle 14 zugekehrten Stützwagens 2 des Stützwagenzuges mit der ortsfesten Ablaufstelle 14 ebenfalls über Zugglieder 13 erfolgt. Zum Unterschied zu den bekannten Zuggliedern, die aus Ketten vorgegebener Länge bestehen, werden die Zugglieder 13 gemäß dem Ausführungsbeispiel von Gummibändern oder -seilen gebildet, die bezüglich ihrer Länge ausziehbar sind. Die Anordnung ist dabei so getroffen, daß die Zugglieder 13 mit ihren beiden Enden an einem Stützwagen angreifen und um Umlenkrollen 15 des jeweils benachbarten Stützwagens 2 geführt sind. In analoger Weise sind an der Ablaufstelle 14 Umlenkrollen 15 und am Schlingenwagen 1 Verankerungen vorgesehen, um zwischen den endseitigen Stützwagen des Stützwagenzuges und der Ablaufstelle 14 einerseits und dem Schlaufenwagen anderenseits eine entsprechende Zugglied-Verbindung sicherzustellen.The individual support wagons 2 are connected to one another by tension members 13, the connection of the support wagon 2 directly adjacent to the loop wagon 1 with the loop wagon 1 and the support wagon 2 of the support wagon train facing a fixed drainage point 14 with the fixed drainage point 14 likewise being effected via tension members 13. In contrast to the known tension members, which consist of chains of a predetermined length, the tension members 13 according to the embodiment are formed by rubber bands or ropes which can be pulled out with respect to their length. The arrangement is such that the tension members 13 engage with their two ends on a support carriage and are guided around deflection rollers 15 of the adjacent support carriage 2. In an analogous manner, deflection rollers 15 and on the loop carriage 1 are provided at anchor points 14 in order to ensure a corresponding tension member connection between the end support carriage of the support carriage train and the discharge point 14 on the one hand and the loop carriage on the other.

Da die Zugglieder 13 bei kürzestem Abstand der Stützwagen 2 voneinander gespannt sind, müssen die Zugglieder 13 beim Verfahren des Schlaufenwagens 1 im Sinne einer Schlaufenvergrößerung gegen die elastische Rückstellkraft ausgezogen werden. Da die Rückstellkraft der Zugglieder 13 größer als der Fahrwiderstand des Stützwagenzuges gewählt ist, werden alle Zugglieder 13 zugleich ausgezogen, was nicht nur ein stoßfreies Anfahren der Stützwagen 2 gewährleistet, sondern auch eine gleichmäßige Verteilung der Stützwagen 2 über die Schlaufenlänge sicherstellt. Wird der Schlaufenwagen im Sinne einer Schlaufenverringerung verfahren, so werden über die Rückstellkräfte der Zugglieder die Stützwagen 2 gegeneinander und gegen die Ablaufstelle 14 gezogen, so daß wiederum eine gleichmäßige Aufteilung der Stützwagen 2 auf die Schlaufenlänge erfolgt.Since the tension members 13 are tensioned at the shortest distance between the support carriages 2, the tension members 13 have to be pulled out against the elastic restoring force when the loop carriage 1 is being moved in the sense of an enlargement of the loop. Since the restoring force of the tension members 13 is selected to be greater than the running resistance of the support car train, all the tension members 13 are pulled out at the same time, which not only ensures a smooth start of the support car 2, but also ensures a uniform distribution of the support car 2 over the loop length. If the loop carriage is moved in the sense of a loop reduction, the support carriages 2 are pulled against one another and against the drain point 14 via the restoring forces of the tension members, so that the support carriages 2 are evenly distributed over the loop length.

Wegen der Zuggliedführung über die Umlenkrollen 15 wird auf beiden Längsseiten des Stützwagenzuges 2 stets eine symmetrische Stützwagenbelastung erzielt, auch wenn die Rückstellkräfte der einzelnen Zugglieder nicht gleich sein sollten. Solche Unregelmäßigkeiten hinsichtlich der Rückstellkräfte bedingen ungleichmäßige Abstände zwischen den Stützwagen 2. Damit gleiche Stützwagenabstände sichergestellt werden können, können die Zugglieder 13 mit Spanneinrichtungen versehen sein, über die die Rückstellkräfte eingestellt und aufeinander abgestimmt werden.Because of the tension member guidance via the deflection rollers 15, a symmetrical support car loading is always achieved on both longitudinal sides of the support car train 2, even if the restoring forces of the individual tension members should not be the same. Such irregularities with regard to the restoring forces necessitate uneven distances between the support carriages 2. In order that the same support carriage spacings can be ensured, the tension members 13 can be provided with tensioning devices by means of which the restoring forces are adjusted and coordinated with one another.

Damit entsprechende Dehnungslängen für die Zugglieder erreicht werden, müssen die Zugglieder eine bestimmte Mindestlänge aufweisen, wobei sich die zufolge des gegebenen kleinsten Abstandes zwischen den Stützwagen 2 bestimmte Zuggliedlänge nicht immer der Forderung nach einer erwünschten Dehnungslänge unterordnen läßt. Um hier Abhilfe zu schaffen, sind die Zugglieder 13 nach Fig. 3 in Form einer zusätzlichen Schlinge 16 zwischen den Umlenkrollen 15 hin- und hergeführt, so daß mit dieser Schlingenbildung auf alle Fälle eine ausreichende Länge erreicht wird.In order that corresponding elongation lengths can be achieved for the tension members, the tension members must have a certain minimum length, whereby the length of the tension member determined due to the given smallest distance between the support carriages 2 cannot always be subordinated to the demand for a desired expansion length. In order to remedy this, the tension members 13 according to FIG. 3 in the form of an additional loop 16 are guided back and forth between the deflection rollers 15, so that a sufficient length is achieved in any case with this loop formation.

Die Erfindung ist selbstverständlich nicht auf das dargestellte Ausführungsbeispiel beschränkt. So könnten beispielsweise die elastisch dehnbaren Zugglieder 13 durch undehnbare Zugglieder ersetzt werden, die auf federbelasteten Speichertrommeln aufgewickelt sind und aus diesen Speichern gegen eine entsprechende Rückstellkraft ausgezogen werden. Entscheidend für eine gleichmäßige Verteilung der Stützwagen 2 über die Schlaufenlänge ist, daß die Zugglieder gleichmäßig gegen eine Rückstellkraft ausziehbar sind, wobei es gleichgültig ist, ob diese Rückstellkräfte über das elastische Dehnungsverhalten der Zugglieder oder über gesonderte Rückstellfedern erreicht werden.The invention is of course not limited to the illustrated embodiment. For example, the elastically stretchable tension members 13 could be replaced by inextensible tension members which are wound on spring-loaded storage drums and pulled out of these stores against a corresponding restoring force. It is crucial for a uniform distribution of the support car 2 over the loop length that the tension members can be pulled out evenly against a restoring force, it being immaterial whether these restoring forces are achieved via the elastic expansion behavior of the tension members or via separate return springs.
