Abstract

An einem Walzband-Haspel, dessen Trommel (10) aus mehreren spreizbaren Segmenten (8) besteht, werden die Segmente (8) über keilförmig ausgebildete Stützflächen (9) unmittelbar an ebenfalls keilförmigen Auflageflächen (7) einer Hohlwelle (1) abgestützt. Mittels eines in der Hohlwelle (1) axial verschiebbar geführten Stempels (12), der an den Segmenten (8) angreift, werden diese bei ihrer Verschiebung durch das Zusammenwirken der keilförmigen Stützflächen (9) und der Auflageflächen (7) gleichzeitig radial gespreizt oder zusammengezogen. Da die mit dem Spreizen oder Zusammenziehen der Trommel (10) einhergehende Axialverschiebung derselben den ordnungsgemäßen Ablauf des Walzbandes in die dem Haspel nachgeordneten Verarbeitungsanlagen beeinträchtigen kann, wird die Relativverschiebung (15) bzw. (16) zwischen den Segmenten (8) und der Hohlwelle (1) durch ein Meßglied (21) abgegriffen und in eine entgegengesetzte Verschiebebewegung des Haspelgehäuses (3) auf dem Haspelbett (4) von entsprechender Größe durch einen Antrieb (5) umgesetzt. Damit behalten dann die Segmente (8) während ihrer das Festspannen des Bandbundes (17) bewirkenden Bewegung (25) immer ihre vorbestimmte Relativlage zur Ablaufmittellinie (20-20) bei.The segments (8) are supported directly on wedge-shaped support surfaces (9) of a hollow shaft (1) on a rolled strip reel, the drum (10) of which consists of several expandable segments (8). By means of a plunger (12) which is axially displaceably guided in the hollow shaft (1) and which engages the segments (8), these are simultaneously radially spread or contracted during their displacement by the interaction of the wedge-shaped support surfaces (9) and the bearing surfaces (7) . Since the axial displacement of the drum (10) associated with the spreading or contraction of the drum can impair the proper running of the rolled strip into the processing plants downstream of the reel, the relative displacement (15) or (16) between the segments (8) and the hollow shaft ( 1) tapped by a measuring element (21) and converted into an opposite displacement movement of the reel housing (3) on the reel bed (4) of appropriate size by a drive (5). The segments (8) thus always maintain their predetermined relative position to the drain center line (20-20) during their movement (25) which causes the band bundle (17) to be tightened.

Description

Die Erfindung betrifft ein Verfahren zum Betrieb eines Walzband-Haspels, dessen Trommel aus mehreren spreizbaren Segmenten besteht, welche sich mit keilförmig ausgebildeten Auflageflächen axial verschiebbar gegen eine im Haspelgehäuse drehbar gelagerte zentrale Hohlwelle abstützen und mittels eines in der Hohlwelle angeordneten Stempels verstellt werden.The invention relates to a method for operating a rolled strip reel, the drum of which consists of a plurality of expandable segments which, with wedge-shaped support surfaces, are axially displaceably supported against a central hollow shaft rotatably mounted in the reel housing and are adjusted by means of a punch arranged in the hollow shaft.

Ferner befaßt sich die Erfindung mit einem Walzband-Haspel zur Ausübung des Verfahrens, der mit einem das Ein- und Ausschieben der Haspeltrommel relativ zum Bandbund und/oder die Bandmittensteuerung bewirkenden Verschiebeantrieb für das Haspelgehäuse ausgerüstet ist.Furthermore, the invention is concerned with a rolled strip reel for carrying out the method, which is equipped with a displacement drive for the reel housing which effects the pushing in and out of the reel drum relative to the coil and / or the belt center control.

Durch die DE-AS 10 o7 279 und die DE-PS 17 52 185 sind bereits Walzband-Haspel bekannt, deren Trommel aus mehreren spreizbaren Segmenten besteht, welche sich mit keilförmig ausgebildeten Auflageflächen axial verschiebbar unmittelbar gegen eine in einem Haspelgehäuse drehbar gelagerte, zentrale Hohlwelle abstützen, und dabei mittels eines in der Hohlwelle angeordneten Stempels relativ zu dieser verstellt werden.From DE-AS 1 0 o7 279 and DE-PS 17 52 185 rolled strip reels are already known, the drum of which consists of several expandable segments which are axially displaceable with wedge-shaped bearing surfaces directly against a central bearing rotatably mounted in a reel housing Support the hollow shaft, and be adjusted relative to the latter by means of a plunger arranged in the hollow shaft.

Solche Walzband-Haspel sind gegenüber derjenigen Bauart, wie sie beispielsweise der DL-PS 34 24o zu entnehmen ist, insofern vorteilhaft, als durch die unmittelbare Abstützung der Trommelsegmente am Umfang der Hohlwelle verhältnismäßig kleine Baumaße erreicht werden können, die eine beträchtliche Verminderung der Schwungmomente zur Folge haben. Hierdurch reduzieren sich naturgemäß auch die während des Betriebs auftretenden Deschleunigungs-, Brems- und Schnellstopmomente. Auch die Lagerdurchmesser für die Haspelwelle können beträchtlich verringert werden, so daß selbst bei Erhöhung der Betriebsdrehzahlen der Lagerverschleiß verringert wird.Such rolled strip reels are advantageous over the type, as can be seen, for example, from DL-PS 34 24o, in that relatively small dimensions can be achieved by the direct support of the drum segments on the circumference of the hollow shaft, which reduce the momentum considerably Have consequence. This naturally also reduces the deceleration, braking and rapid stop moments that occur during operation. The bearing diameter for the reel shaft can also be reduced considerably, so that the bearing wear is reduced even when the operating speeds are increased.

Eine Unzulänglichkeit bei den Walzband-Haspeln nach der DE-ÄS 10 o7 279 und der DE-PS 17 52 185 liegt jedoch darin, daß beim Spreizen der Trommelsegmente zugleich eine Axialverschiebung derselben relativ zur Haspelwelle stattfindet, welche den ordnungsgemäßen Ablauf des Walzbandes in die dem Haspel nachge- ordneten Weiterverarbeitungsanlagen beeinträchtigen kann, wenn im Anschluß an die Festspannung des Bandbundes auf der Haspel- trommel keine entsprechende Lagenkorrektur des gesamten Haspels relativ zur nachgeordneten Weiterverarbeitungsanlage vorgenommen wird. Eine solche Lagenkorrektur des gesamten Walzband-Haspels läßt sich zwar mit Hilfe des Verschiebeantriebs bewirken, welcher einerseits für das Ein- und Ausschieben der Haspeltrommel relativ zum Bandbund und/oder auch zur Mittensteuerung des Bandbundes sowieso erforderlich ist. Die Vornahme einer solchen nachträglichen Lagenkorrektur ist jedoch verhältnismäßig zeitraubend und erfordert außerdem viel Geschicklichkeit der Bedienungsleute.An inadequacy in the rolled strip reels according to DE-A 1 0 o7 279 and DE-PS 17 52 185, however, lies in the fact that when the drum segments are spread there is at the same time an axial displacement thereof relative to the reel shaft, which ensures that the rolled strip runs properly in the downstream processing systems downstream of the reel can be impaired if, following the fixed tension of the coil on the reel drum, no corresponding position correction of the entire reel relative to the downstream processing system is carried out. Such a position correction of the entire rolled strip reel can indeed be effected with the aid of the displacement drive, which is necessary anyway for inserting and removing the reel drum relative to the strip coil and / or for center control of the strip coil anyway. However, performing such a posture correction is relatively time consuming and also requires a great deal of skill on the part of the operators.

Zweck der Erfindung ist es, die bei den vorstehend beschriebenen, bekannten Walzbandhaspeln noch gegebene Unzulänglichkeit zu vermeiden. Daher liegt der Erfindung die Aufgabe zugrunde, ein Verfahren zum Betrieb eines gattungsgemäßen Walzband-Haspels aufzufinden und einen Walzband-Haspel zur Ausübung dieses Verfahrens zu schaffen, welches bzw. welcher unmittelbar nach dem Spannvorgang ein einwandfreies Abwickeln des Walzbandes vom Bandbund ermöglicht.The purpose of the invention is to avoid the inadequacy that still exists in the known rolled strip reels described above. It is therefore the object of the invention to find a method for operating a generic rolled strip reel and to create a rolled strip reel for carrying out this method, which enables the rolled strip to be unwound properly from the strip immediately after the tensioning process.

Die Lösung dieser Aufgabe wird verfahrenstechnich auf einfache Weise dadurch erreicht, daß die Relativverschiebung zwischen den Segmenten und der Hohlwelle abgegriffen und in eine entgegengesetzte Verschiebebewegung des Haspelgehäuses auf dem Haspelbett von entsprechender Größe umgesetzt wird.This object is achieved in a simple manner in terms of process technology by tapping the relative displacement between the segments and the hollow shaft and converting it into an opposite displacement movement of the reel housing on the reel bed of a suitable size.

Aufgrund dieser verfahrenstechnischen Maßnahme erhalten die Trommelsegmente während ihrer das Festspannen des Bandbundes bezweckenden Bewegung immer ihre vorbestimmte Relativlage zur Einlauf-Mittellinie der dem Haspel nachgeordneten Verarbeitungsanlagen bei und stellen damit sicher, daß der Walzband-Haspel unmittelbar nach Beendigung des Spannvorgangs ohne weiteres in Betrieb gesetzt werden kann.As a result of this procedural measure, the drum segments always receive their predetermined relative position to the center line of the infeed of the processing systems downstream of the reel during their movement for tightening the coil, thus ensuring that the rolled reel is immediately put into operation immediately after the tensioning process has ended can.

Nach einer verfahrenstechnischen Weiterbildung hat es sich als vorteilhaft erwiesen, wenn erfindungsgemäß die Relativverschiebung des Stempels zur Hohlwelle gemessen und als Stellgröße für den Verschiebeantrieb des Haspelgehäuses benutzt wird. Da nämlich die Relativverschiebung des Stempels zur Hohlwelle der Relativverschiebung zwischen den Segmenten der Haspeltrommel und der sie tragenden und führenden Hohlwelle entspricht, läßt sich auf diesem Wege die jeweilige Korrekturgröße vom einfachsten und mit geringstmöglichem relativem Fehler.ermitteln.According to a further development in process engineering, it has proven to be advantageous if, according to the invention, the relative displacement of the plunger to the hollow shaft is measured and used as a manipulated variable for the displacement drive of the reel housing. Since the relative displacement of the plunger relative to the hollow shaft corresponds to the relative displacement between the segments of the reel drum and the hollow shaft carrying and guiding it, the respective correction quantity can be determined in this way from the simplest and with the least possible relative error.

Ein Walzband-Haspel zur Ausübung dieses Verfahrens, welcher mit einem das Ein- und Ausschieben der Haspeltrommel relativ zum Bandbund und/oder die Bandmittensteuerung bewirkenden Verschie- beantrieb für das Haspelgehäuse ausgestattet ist, zeichnet sich erfindungsgemäß im wesentlichen dadurch aus, daß zwischen den Segmenten und der Hohlwelle eine Meßvorrichtung angeordnet ist, . die mit einem Steuerorgan für den Verschiebeantrieb in Verbindung steht.A reel tape reel for practicing this method, which is provided with a switching on and pushing out of the reel drum relative to the strip coil and / or the strip center control effecting displacement - is equipped beantrieb for the reel housing, is characterized according to the invention substantially by the fact that between the segments and a measuring device is arranged on the hollow shaft,. which is connected to a control element for the displacement drive.

Hierbei hat es sich als besonders vorteilhaft erwiesen, wenn nach einem weiteren Merkmal der Erfindung die Meßvorrichtung mit dem hinteren Ende des die Segmente verschiebenden Stempels in Stellverbindung steht und das dem Verschiebeantrieb zugeordnete Steuerorgan wegabhängig ein- und verstellbar ist. Dieses Steuerorgan kann dabei im Grunde genommen einen ähnlichen Aufbau haben wie die den Segmenten bzw. dem Stempel zugeordnete Meßvorrichtung, wobei die Meßvorrichtung und das Steuerorgan gewissermaßen gegenläufig zusammenarbeiten und hierdurch die jeweilige Stellgröße für den Verschiebeantrieb bilden.It has proven to be particularly advantageous if, according to a further feature of the invention, the measuring device with the rear end of the stamp displacing the segments is in actuating connection and the control element assigned to the displacement drive can be adjusted and adjusted depending on the travel. This control element can basically have a similar structure to the measuring device assigned to the segments or the stamp, the measuring device and the control element cooperating to a certain extent in opposite directions, thereby forming the respective manipulated variable for the displacement drive.

Schließlich wird ein Erfindungsmerkmal auch noch darin gesehen, daß sowohl der Spreizantrieb für die Trommelsegmente als auch der Verschicbeantricb jeweils aus einem doppelt wirkenden Hydraulikzylinder besteht, und daß die Druckflüssigkeitenzufuhr zum Verschiebeantrieb über ein durch die Meßvorrichtung steuerbares Regelventil beeinflußbar ist.Finally, an inventive feature is also seen in the fact that both the expansion drive for the drum segments and the shifting actuator each consist of a double-acting hydraulic cylinder, and that the hydraulic fluid supply to the shifting drive can be influenced by a control valve that can be controlled by the measuring device.

The invention will now be explained in detail with reference to a drawing. It shows
  • 1 shows a schematically simplified side view of a rolled strip reel according to the invention before the reel drum is moved into the coil,
  • F ig. 2 shows a representation of the rolled strip reel corresponding to FIG. 1 with the reel drum axially retracted but still contracted into the opening of the strip coil,
  • Fig. 3 again in a schematically simplified side view of the rolled strip reel according to FIGS. 1 and 2 with the drum to set the band bundle radially spread while
  • Fig. 4 shows on a larger scale and partly in section the structure of the reel drum, in the lower half with contracted and in the upper half with spread segments.

In der Zeichnung ist ein Walzband-Haspel gezeigt, dessen Hohlwelle 1 axial unverschiebbar, jedoch drehantreibbar in Wälzlagern 2 des Haspelgehäuses 3 lagert.In the drawing, a rolled strip reel is shown, the hollow shaft 1 of which is axially immovable but can be driven in rotation in roller bearings 2 of the reel housing 3.

Das Haspelgehäuse 3 ist dabei auf einem ortsfesten Haspelbett 4 in Richtung der Längsachse der Hohlwelle 1 verschiebbar geführt und läßt sich auf diesem durch einen, beispielsweise als Hydraulikzylinder ausgebildeten Verschiebeantrieb 5 bewegen.The reel housing 3 is guided displaceably on a stationary reel bed 4 in the direction of the longitudinal axis of the hollow shaft 1 and can be moved thereon by a displacement drive 5, for example a hydraulic cylinder.

An ihrem vorderen, fliegend angeordneten Ende ist die Hohlwelle 1 mit keilförmig angeordneten Auflageflächen 7 versehen, auf denen sich mehrere, bspw. vier, Segmente 8 über ebenfalls keilförmig ausgebildete Stützflächen 9 gehalten und geführt. Die Segmente 8 bilden dabei gemeinsam die eigentliche Haspeltrommel 10, welche sich bedarfsweise in Radialrichtung spreizen oder aber zusammenziehen läßt, und zwar dadurch, daß die mit ihren keilförmigen Stützflächen 9 auf den keilförmigen Auflageflächen 7 der Hohlwelle 1 gehaltenen Segmente 8 gleichzeitig relativ zur Hohlwelle 1 axial verschoben werden.At its front, overhung end, the hollow shaft 1 is provided with wedge-shaped support surfaces 7, on which several, for example four, segments 8 are held and guided by support surfaces 9 which are also wedge-shaped. The segments 8 case form together the actual reel drum 1 0, which, if required, spread out in the radial direction or can but to contract, namely the fact that the segments 8 held with its wedge-shaped support surfaces 9 on the wedge-shaped bearing surfaces 7 of the hollow shaft 1 at the same time relative to the hollow shaft 1 be moved axially.

Die Axialverschiebung der Segmente 8 relativ zur Hohlwelle 1 wird durch einen Stempel 12 erzwungen, welcher zentrisch durch die Hohlwelle 1 geführt ist, sowie einerseits vor dem vorderen Ende der Hohlwelle 1 über einen Mitnehmerflansch 13 an den Segmenten 8 angreift, während er andererseits durch einen am hinteren Ende der Hohlwelle 1 angeordneten Hydraulikzylinder 14 axial verschoben werden kann.The axial displacement of the segments 8 relative to the hollow shaft 1 is forced by a plunger 12 which is guided centrally through the hollow shaft 1 and, on the one hand, engages the segments 8 via a driver flange 13 in front of the front end of the hollow shaft 1, while on the other hand by a rear end of the hollow shaft 1 arranged hydraulic cylinder 14 can be moved axially.

Wie Fig. 4 in der unteren Hälfte erkennen läßt, ist die Haspeltrommel 1o radial zusammengezogen bzw. kontrahiert, wenn der Stempel 12 durch den Hydraulikzylinder 14 nach links geschoben wurde. Zum Spreizen der Trommel 1o ist es hingegen notwendig, den Stempel 12 durch den Hydraulikzylinder 14 nach rechts zu ziehen, wie das aus der oberen Hälfte der Fig. 4 hervorgeht.As can be seen in FIG. 4 in the lower half, the reel drum 10 is contracted or contracted radially when the plunger 12 has been pushed to the left by the hydraulic cylinder 14. For spreading the drum 1o, however, it is necessary to pull the punch 12 through the hydraulic cylinder 14 to the right, as can be seen from the upper half of FIG. 4.

Zum Zwecke des radialen Spreizens und Zusammenziehens der Haspeltrommel 1o ist dabei eine Axialverschiebung des Stempels 12 maximal um das Maß 15 relativ zur Hohlwelle 1 bzw. eine entsprechende Axialverschiebung der einzelnen Segmente 8 um das Maß 16 relativ zur Hohlwelle 1 notwendig (Fig. 4).For the purpose of radial expansion and contraction of the reel drum 1o, an axial displacement of the plunger 12 by a dimension 15 relative to the hollow shaft 1 or a corresponding axial displacement of the individual segments 8 by a dimension 16 relative to the hollow shaft 1 is necessary (FIG. 4).

Zum Zwecke der Aufnahme des Bandbundes 17 durch die Haspeltrommel 1o muß zunächst der gesamte Walzband-Haspel bei radial zusammengezogener Haspeltrommel 1o auf dem ortsfesten Haspelbett 5 aus der Stellung nach Fig. 1 in die Stellung nach Fig. 2 geschoben werden. Diese Bewegung wird durch den Verschiebeantrieb 5 bewirkt und beispielsweise durch einen End- < schalter 18 begrenzt, indem dieser die Zufuhr der Hydraulik - flüssigkeit zum Hydraulikzylinder 5 unterbricht. Dabei bestimmt der Endschalter 18 die den ordnungsgemäßen Bandablauf in die Weiterverarbeitungsanlage gewährleistende Grundstellung des Walzband-Haspels. Diese Grundstellung des Walzband-Haspels läßt sich dann bedarfsweise während des Abwickclbctriebs noch durch eine sogenannte Bandmittensteuerung selbsttätig korrigieren, und zwar durch entsprechende Beeinflussung des Verschiebeantriebs 5.For the purpose of receiving the band coil 17 by the reel drum 1o, the entire rolled strip reel with the radially contracted reel drum 1o must first be pushed onto the stationary reel bed 5 from the position shown in FIG. 1 to the position shown in FIG. 2. This movement is caused by the displacement drive 5 and limited for example by an end <switches 18 by this supplying the hydraulic - liquid interrupts to the hydraulic cylinder. 5 In this case, the limit switch 18 determines the basic position of the rolled strip reel which ensures the proper strip run into the further processing system. This basic position of the rolled strip reel can then, if necessary, be automatically corrected during the unwinding drive by a so-called strip center control, by influencing the displacement drive 5 accordingly.

Bevor jedoch der Walzband-Haspel zum Abwickeln des Bandes in Betrieb gesetzt werden kann, muß zunächst die Haspeltrommel 10 innerhalb der zentrischen Öffnung 19 des Bandbundes 17 gespreizt werden. Da aber diese Spreizbewegung mit einer Axialverschiebung der Trommelsegmente 8 relativ zur Hohlwelle 1 bzw. zum Haspelgehäuse 3 einhergeht,.muß dafür gesorgt werden, daß die hieraus resultierende Axialverlagerung des Bandbundes 17 aus seiner Ablauf-Mittelebene 2o-2o praktisch vollständig eliminiert wird. Um das zu erreichen, ist zwischen der Hohl-- welle 1 und dem darin verschiebbaren Stempel 12 eine Meßvorrichtung 21 angeordnet, welche die jeweilige Relativverschiebung zwischen diesen beiden Teilen exakt ermittelt und in eine Stell- . größe umformt, welche den Verschiebeantrieb 5 für das Haspelgehäuse 3 beeinflußt und zwar in der Weise, daß das Haspelgehäuse 3 völlig selbsttätig und jeweils um das entsprechende Ausmaß auf dem ortsfesten Haspclbett 4 in entgegengesetzter Richtung zur Axialverstellung der Trommelsegmente 8 verschoben wird.However, before the reel tape reel can be set for unwinding the band in operation, initially, the reel drum 1 0 must the strip coil 17 is spread within the central opening 19th However, since this spreading movement is accompanied by an axial displacement of the drum segments 8 relative to the hollow shaft 1 or to the reel housing 3, care must be taken to ensure that the resulting axial displacement of the band collar 17 from its running center plane 2o-2o is practically completely eliminated. In order to achieve this, a measuring device 21 is arranged between the hollow shaft 1 and the plunger 12 displaceable therein, which precisely determines the respective relative displacement between these two parts and converts it into an actuating device. Formed size, which affects the displacement drive 5 for the reel housing 3 in such a way that the reel housing 3 is completely automatically and in each case moved by the appropriate amount on the stationary reel bed 4 in the opposite direction to the axial adjustment of the drum segments 8.

Als Steuerorgan für das die Hydraulikzufhr zum Verschiebcantr bewirkende Regelventil 22 kann dabei ein Stellwertgeber 23 Verwendung finden, indem einerseits fortwährend die von der Meßvorrichtung 21 ermittelten Meßgröße eingegeben werden und wele andererseits von einer zwischen dem Haspelbett 4 und dem Haspe gehäuse 3 angeordneten Streckenmeßvorrichtung 24 beeinflußt wi Die Meßvorrichtung 21 und die Streckenmeßvorrichtung 24 arbeit dabei mit dem Stellwertgeber 23 in der Weise zusammen, daß letzterer das Regelventil 22 geöffnet hält, solange eine Diffc zwischen den von der Meßvorrichtung 21 und den von der Strecke meßvorrichtung 24 ermittelten Meßwerten besteht. Erst wenn die Differenz zwischen den beiden von der Meßverrichtung 21 und de Streckenmeßvorrichtung 24 ermittelten Meßwerte im Stellwertgel 23 Null geworden ist, schließt der Stellwertgeber 23 das Riege ventil 22 und setzt damit den Verschiebeantrieb 5 außer Be-trieb.As a control element for the hydraulic supply to the shifting control valve 22, a control value sensor 23 can be used, on the one hand, by continuously entering the measured variable determined by the measuring device 21 and, on the other hand, being influenced by a distance measuring device 24 arranged between the reel bed 4 and the hasp wi The measuring device 21 and the distance measuring device 24 work together with the actuating value transmitter 23 in such a way that the latter keeps the control valve 22 open as long as there is a difference between the measured values determined by the measuring device 21 and the measuring device 24 measured by the distance. Only when it is to become the difference between the two of the Meßverrichtung 21 and de Streckenmeßvorrichtung 24 measured values determined in Stellwertgel 23 zero, the adjustment value generator 23 closes the valve 22 ranks, and thus sets the displacement drive 5 e-drive except B.

Da die Meßvorrichtung 21 und die Streckenmcßvorrichtung 24 ge läufig arbeiten, wird der Verschiebeantrieb 5 zwangaläufig in Pfeilrichtung 26 so gesteuert, daß er sich entgegengesetzt zur Verschieberichtung 25 der Haspeltrommel lo bewegt und dadurch den Eandbund 17 immer exakt auf der Ablaufmittelebene 20 hält.Since the measuring device 21 and the distance measuring device 24 are in common operation, the displacement drive 5 is inevitably controlled in the direction of the arrow 26 so that it moves in the opposite direction to the displacement direction 25 of the reel drum 10 and thereby keeps the flange 17 always exactly on the drainage medium level 20.

Da die Streckenmeßvorrichtung 24 zwischen dem Haspelbett 4 unc dem Haspclgchäuse 3 erst in Tätigkeit treten dair, nachdem der Walzband-Haspel aus der Stellung nach Fig. 1 in die Stellung nach Fig. 2 gefahren ist, kann der in diesem Falle den Verschi beantrieb 5 stillsetzende Endschalter 18 geleichzeitig benutzt werden, um die Streckenmeßvorrichtung 24 wirksam zu machen.Since the distance measuring device 24 between the reel bed 4 and the reel housing 3 only come into action after the rolling-band reel has moved from the position according to FIG. 1 into the position according to FIG. 2, in this case the drive 5 can shut down Limit switches 18 can be used at the same time to make the distance measuring device 24 effective.

Es ist ohne weiteres möglich, sowohl die Meßvorrichtung 21 als auch die Streckenmeßvorrichtung 24 auf kapazitivem oder induktivem Wege arbeiten zu lassen und den zugehörigen Stellwertgebc 23 als eine Meßbrücke auszubilden, die in Abhängigkeit von ihre jeweiligen Zustand das Regelventil 22 entweder öffnet oder schließt.It is easily possible to have both the measuring device 21 and the distance measuring device 24 work capacitively or inductively and to design the associated actuating value transmitter 23 as a measuring bridge which either opens or closes the control valve 22 depending on its respective state.

Mit einem geringen technischen Mehraufwand läßt sich durch die vorstehend beschriebenen Maßnahmen ein Walzband-Haspel erstellen, dessen Haspeltrommel 1o völlig selbsttätig und exakt auf die vorbestimmte Ablauf-Mittelebene 2o-2o ausgerichtet wird, obwohl deren Segmente 8 zum Zwecke des Spreizens oder kontrahierens relativ zu der sie tragenden Hohlwelle 1 einer Axialverschiebung unterworfen werden müssen.With a little additional technical effort, the measures described above can be used to create a rolled strip reel, the reel drum 1o of which is completely automatically and precisely aligned with the predetermined center flow level 2o-2o, although its segments 8 are used for the purpose of spreading or contracting relative to that they supporting hollow shaft 1 must be subjected to an axial displacement.

Abschließend sei noch darauf hingewiesen, daß die vorstehend beschriebene Betriebsweise und die zu deren Ausübung vorgesehene Steueranordnung nicht nur bei Walzband-Haspeln mit einer fliegend gelagerten Haspeltrommel benutzt werden können. Vielmehr sind sie auch bei sogenannten Doppelhaspeln gleichermaßen gut einsetzbar, bei welchen zwei Haspeltrommeln 1o von entgegengesetzten Seiten her in ein und denselben Bandbund eingefahren werden.Finally, it should also be pointed out that the above-described mode of operation and the control arrangement provided for exercising it can not only be used in the case of rolled strip reels with an overhung reel drum. Rather, they can also be used equally well in so-called double reels, in which two reel drums 1o are inserted into one and the same band bundle from opposite sides.
