Abstract

The flap guide (20) can selectively be moved into at least two positions. In a first position, the guide locates on at least one of the clamp rollers (10,12) so that it impedes it. The band (14) is thus forced to deviate from a normal path in order at an angle to follow a path to the winding pin (16) and a second position in which the guide does not locate on the clamp roller. This process prevents unnecessary wear or groove formation on the surface of the clamp rollers during winding after the band has been brought into engagement with the winding pin and wound around it.

Description

Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung für die Führung von dünnem Stahlband, das in einem kontinuierlichen Walzwerk aufgewickelt wird, um zu verhindern, daß sich das genannte Stahlband um andere Rollen als den beabsichtigten Wickeldorn wickelt. Die Erfindung ist besonders geeignet für Anwendungen, bei denen warmgewalztes Stahlband aus stranggegossenen Brammen oder Stäben produziert wird.The present invention relates to a thin steel strip guide method and apparatus which is wound in a continuous rolling mill to prevent the said steel strip from winding around rollers other than the intended winding mandrel. The invention is particularly suitable for applications where hot rolled steel strip is produced from continuously cast slabs or bars.

Die typische Anwendung des Erfindungsgegenstandes wird beispielsweise notwendig, wenn bei Metallbandwalzwerken die Stärke des Bandes unter 2 mm beträgt und insbesondere bei Stahl, wenn die Stärke unter 1,5 mm beträgt.The typical application of the subject invention becomes necessary, for example, in metal strip rolling mills, when the thickness of the strip is less than 2 mm, and particularly in the case of steel, when the thickness is less than 1.5 mm.

Dünnes warmgewalztes Stahlband wird im allgemeinen hergestellt, indem die Dicke von gegossenen Brammen in aufeinanderfolgenden Walzschritten verringert wird, bis die gewünschte Bandstärke erreicht ist. Am Ende des Walzwerks befindet sich normalerweise eine Wickelmaschine, auf der das Band zum Transport zu einem Bund aufgewickelt wird.Thin hot rolled steel strip is generally made by reducing the thickness of cast slabs in successive stages of rolling until the desired strip thickness is achieved. At the end of the rolling mill is usually a winding machine on which the tape is wound up for transport to a bundle.

Die Wickelmaschine umfaßt mehrere Stützwalzen und mindestens ein Paar Klemmrollen, die das Band in der gewünschten Geschwindigkeit und mit der gewünschten Spannung antreiben, bevor es in Eingriff mit einem Wickeldorn gebracht und auf diesen aufgewickelt wird.The winding machine comprises a plurality of back-up rollers and at least one pair of pinch rollers which drive the band at the desired speed and tension before being brought into engagement with and wound onto a winding mandrel.

Die Klemmrollen sind üblicherweise in einer höheren Position im Verhältnis zur Rolle der Wickelmaschine angeordnet, und eine Reihe von Führungsblechen zwingt das Band zum Wickeldorn. Wickelmaschinen nach dem Stand der Technik umfassen eine schwenkbar bewegliche Klappenführung, die ihre Position so ändern kann, daß sie in Werken, die zur Steigerung der Produktivität des Walzwerks mit mehreren Wickeldornen ausgestattet sind, das vordere Bandende in Richtung auf einen von einer Mehrzahl von Wickeldornen umlenkt.The pinch rollers are usually located in a higher position relative to the reel spool, and a series of guide plates force the tape to the mandrel. Prior art winding machines include a pivotally movable flap guide which can change its position to deflect the leading end of the tape toward one of a plurality of winding mandrels in factories equipped to increase the productivity of the multiple mandrel rolling mill ,

Bei Klappenführungen nach dem Stand der Technik bleibt ein Spalt von mindestens 1 bis 2 mm zwischen dem Führungsende und der oberen Klemmrolle, der je nach der erwarteten Bandstärke gewählt wird. Ein kleinerer Spalt wurde bislang aufgrund der normalen Spiel- und Toleranzvariablen nicht als sinnvoll erachtet. Wenn die Stärke des Bandes mehr als etwa 2,0 mm bis 1,5 mm beträgt, treten beim Transport des Bands normalerweise keine Probleme auf, aber wenn die Stärke weniger als etwa 1,5 mm beträgt, kann das Band durch den genannten Spalt laufen und sich um die Klemmrolle wickeln, was zu Verzögerungen führt und Ausschuß verursacht. Je dünner das Band, desto flexibler ist es, und desto höher ist die sich ergebende Geschwindigkeit (üblicherweise mehr als 10m/Sek. bei einer Bandstärke von 1, 5 mm oder weniger). Die hohe Bandgeschwindigkeit führt manchmal dazu, daß sich das vordere Bandende im Durchgang durch die Kühlungseinrichtungen des Werks nach oben hebt, und wenn die Biegung des vorderen Bandendes in etwa der Biegung der Klemmrolle entspricht, ist es sehr wahrscheinlich, daß sich das Band um die genannte Klemmrolle wickelt. Die Erfindung ist somit besonders sinnvoll bei Wickelsystemen in der Herstellung von dünnem Stahlband.In prior art flap guides, there remains a gap of at least 1 to 2 mm between the leading end and the upper pinch roller, which is chosen according to the expected strip thickness. A smaller gap has so far not been considered useful due to the normal play and tolerance variables. When the thickness of the tape is more than about 2.0 mm to 1.5 mm, there are usually no problems in transporting the tape, but if the thickness is less than about 1.5 mm, the tape may pass through the gap and wrap around the pinch roller, causing delays and causing rejects. The thinner the tape, the more flexible it is, and the higher the resulting speed (typically more than 10 m / sec with a tape thickness of 1, 5 mm or less). The high belt speed sometimes causes the front end of the belt to rise in the passageway through the factory's cooling means, and if the leading end of the belt approximates the nip of the pinch roller, it is very likely that the belt will wrap around the belt Pinch roller winds. The invention is therefore particularly useful in winding systems in the production of thin steel strip.

Zwar wurden mehrere Vorschläge geprüft und erprobt, wie das vordere Bandende innerhalb des normalen Weges gehalten werden kann, aber die Lösung dieses Problems wurde schließlich von den Anmeldern entdeckt, als die herkömmliche Klappenführung umgebaut und so betrieben wurde, daß sie kurzzeitig und nicht abrasiv tatsächlich eng an der oberen Klemmrolle anliegt, wenn das vordere Bandende durch die Rolle läuft, wodurch im Effekt der Spalt geschlossen wird (der nach dem Stand der Technik eine notwendige Anforderung war). Um unerwünschten relativ schnellen Verschleiß und Riefenbildung auf der Klemmrollenoberfläche zu vermeiden, die wiederum die Qualität des Bandes beeinträchtigen würden, besteht die Spitze der Klappenführung, die an der Klemmrolle anliegt, aus einem Material mit einem sehr niedrigen Reibungskoeffizienten. Eins der bevorzugten Materialien für diese Anwendung ist ein faserverstärkter Verbundwerkstoff, der als "Micarta" bekannt ist (Warenzeichen der Westinghouse Electric Corporation), der als hartes, nicht abrasives und spanend zu bearbeitendes Material viele Anwendungen findet; aber auch andere Materialien können hierfür verwendet werden, solange sie nicht zu erheblichem Verschleiß oder zu Riefen auf den Klemmrollen führen.While several suggestions have been made as to how the front end of the tape can be kept within the normal path, the solution to this problem was eventually discovered by the applicants when the conventional flap guide was rebuilt and operated to actually be tight for a short time and not abrasive on the upper pinch roller when the front end of the tape passes through the roller, effectively closing the gap (which was a necessary requirement in the prior art). To avoid unwanted, relatively rapid wear and scoring on the pinch roller surface, which in turn would affect the quality of the belt, the tip of the flap guide, which bears against the pinch roller, is made of a material having a very low coefficient of friction. One of the preferred materials for this application is a fiber reinforced composite known as "Micarta" (trademark of Westinghouse Electric Corporation) which finds many uses as a hard, non-abrasive, and machinable material; but other materials can be used for this, as long as they do not lead to significant wear or scoring on the pinch rollers.

Im Patent an Priestley wird eine Bandwickelvorrichtung für das Aufwickeln von kontinuierlichem Band mit relativ hoher Stärke offenbart, deren Aufgabe es ist, unerwünschte Riefen auf dem Band zu verhindern, die durch den Druckaufbau verursacht werden, wenn die Rollen der Wickelmaschine an der Überlappung oder am Punkt des gestiegenen Bunddurchmessers auf das Band treffen, und die ebenfalls darauf abzielt, gebogene Führungen und Flüssigkeitsstrahlen vorzusehen, die auf das vordere Bandende auftreffen, um zu erreichen, daß sich das Band beim Einlaufen in die Wickelmaschine in Richtung auf die Umfangsfläche einer sich drehenden Spule biegt und dagegen gedrückt wird. Dieses Patent sieht nicht die Lösung vor, die von der vorliegenden Erfindung vorgesehen ist, um die bei dünnem Band auftretenden Wickelprobleme zu lösen und weist auch nicht auf eine solche Lösung hin.The Priestley patent discloses a tape winding apparatus for relatively high-speed continuous tape winding, the object of which is to prevent unwanted marks on the tape caused by the build-up of pressure when the winder rolls are at the overlap or at the point of the increased collar diameter hit the band, and the is also intended to provide curved guides and jets of fluid impinging on the front end of the tape to cause the tape to flex as it enters the winding machine towards the peripheral surface of a rotating spool and to be pressed against it. This patent does not provide the solution provided by the present invention to solve the winding problems associated with thin tape, nor does it suggest such a solution.

Im Patent an Johnson wird eine Vorrichtung für das Abwickeln und Richten von Bandmaterial erheblicher Stärke und für die Führung des vorderen Endes des abgewickelten Materials in einen Richt- und Speisemechanismus offenbart. Dieses Patent offenbart jedoch nicht das Problem des Aufwickelns von dünnem Band, das durch die vorliegende Erfindung gelöst wird.The Johnson patent discloses a device for unwinding and straightening strip material of substantial thickness and for guiding the leading end of the unwound material into a straightening and feeding mechanism. However, this patent does not disclose the problem of winding thin tape, which is solved by the present invention.

Im Patent an Ginzburg et al. werden ein Verfahren und eine Vorrichtung für das Aufwickeln von Material auf eine Wickeltrommel entlang einer Bandlaufebene in einem Umkehrwarmwalzwerk beschrieben. Die Vorrichtung umfaßt eine Schürze 34, die von einem Hydraulikzylinder schwenkbar bewegt wird, wird aber nicht verwendet, um zu verhindern, daß sich Bandmaterial um Klemmrollen wickelt.In the patent to Ginzburg et al. For example, a method and apparatus for winding material onto a winding drum along a belt running plane in a reverse hot rolling mill will be described. The apparatus includes a skirt 34 which is pivotally moved by a hydraulic cylinder but is not used to prevent strip material from wrapping around pinch rollers.

Im Patent an Moser wird ein Wickelofen für ein warmgewalztes Band offengelegt, umfassend eine bandaufnehmende Führung mit einem Ende, das in bandaufnehmender Position neben der Wickeltrommel angeordnet ist. Diese Führung ist jedoch nicht dazu gedacht, zu verhindern, daß sich das Band um Klemmrollen wikkelt oder die genannten Rollen berührt.The Moser patent discloses a hot-rolled strip winding furnace comprising a tape-receiving guide having an end disposed in a tape-receiving position adjacent the winding drum. However, this guide is not intended to prevent the belt from worming around pinch rollers or touching said rollers.

Aus der GB - A -1 480 685 ist eine Zweirollen - Treibvorrichtung mit je einer oberen und unteren Treibrolle, die senkrecht übereinander gelagert sind, wobei die Achse der oberen Treibrolle in Banddurchlaufrichtung beim Bandeinlauf in den Haspel hinter der Achse der unteren Treibrolle liegt und nach dem Erfassen des Bandanfanges durch den Wickeldorn des Haspels senkrecht über die Achse der unteren Treibrolle schwenkbar ist und hinter der eine Ablenkvorrichtung für das Band vorgesehen ist. Die Ablenkvorrichtung besteht aus einer Umlenkklappe, die in der vertikalen Stellung der Treibvorrichtung an der unteren Treibrolle oder der oberen Treibrolle anliegt und in jeder anderen Schwenklage der Treibvorrichtung an der oberen Treibrolle anliegt. Unabhängig von der Schwenkbewegung der Treibvorichtung wird die Umlenkklappe mit Hilfe eines Luftzylinders, der am Rahmen befestigt ist und an der Achse der Umlenkklappe angreift, in diese anliegenden Stellungen gebracht.From the GB-A-1 480 685 is a two - roller - driving device, each with an upper and lower drive roller, which are mounted vertically one above the other, the axis of the upper drive roller in the tape passage direction at the tape entry in the reel behind the axis of the lower drive roller and after detecting the Beginning of the tape through the winding mandrel of the reel is vertically pivotable about the axis of the lower drive roller and behind which a deflection device for the tape is provided. The deflection device consists of a deflection flap, which rests in the vertical position of the drive device on the lower drive roller or the upper drive roller and rests in any other pivot position of the drive device on the upper drive roller. Regardless of the pivoting movement of the propellant device, the deflecting flap is brought into these adjacent positions by means of an air cylinder, which is attached to the frame and acts on the axis of the deflecting flap.

In keinem der vorgenannten Patente werden die Probleme angesprochen oder angedeutet, die von der vorliegenden Erfindung gelöst werden, und ihre Lehren enthalten nicht die Konstruktion und den Betrieb einer Führung wie in der vorliegenden Erfindung beansprucht.In none of the aforementioned patents are the problems addressed or suggested by the present invention addressed, and their teachings do not include the construction and operation of a guide as claimed in the present invention.

Eine Aufgabe der vorliegenden Erfindung ist daher ein verbessertes Wickelsystem für den Einsatz in der Produktion von dünnem Stahlband, zum Beispiel bei Wikkelsystemen in Verbindung mit Bandwarmwalzwerken in Stranggußanlagen anzugeben, bei dem ein unnötiger Verschleiß der Klemmrollen und / oder Riefenbildung auf der Oberfläche der Klemmrollen und / oder des Bandes vemieden wird.An object of the present invention is therefore to provide an improved winding system for use in the production of thin steel strip, for example in Wikkelsystemen in connection with strip hot rolling mills in continuous casting, in which an unnecessary wear of the pinch rollers and / or scoring on the surface of the pinch rollers and / or the band is avoided.

Eine weitere Aufgabe der Erfindung ist eine verbesserte Vorrichtung für die Führung eines dünnen Stahlbands zum Dorn einer Wickelmaschine ohne Störung des normalen Betriebs und Beeinträchtigung der hohen Bewegungsgeschwindigkeit der Klemmrollen in der genannten Wickelmaschine.A further object of the invention is an improved device for guiding a thin steel strip to the mandrel of a winding machine without disturbing the normal operation and impairing the high speed of movement of the pinch rollers in said winding machine.

Weitere Aufgaben der Erfindung werden teilweise offensichtlich oder nachfolgend deutlich gemacht.Other objects of the invention will become apparent in part or in the following.

Dementsprechend verfügt ein erfindungsgemäßes Wickelsystem über mehrere Merkmale, die dem genannten Wickelsystem einen zuverlässigen Betrieb ermöglichen und die Betriebskosten von Stahlwerken durch die Verringerung von Stillstandszeiten und Ausbringungsverlusten senken.Accordingly, a winding system according to the invention has several features which allow said winding system to operate reliably and reduce the operating costs of steel mills by reducing downtime and output losses.

Die Aufgaben der vorliegenden Erfindung werden erreicht durch das Wikkelsystem gemäß Anspruch 1 und das Aufwickelverfahren gemäß Anspruch 9. In der ersten Position, in der ein Ende der genannten Führung an einer der genannten Klemmrollen anliegt, wird erreicht, daß sich das dünne Band nicht nach oben um die genannte Klemmrolle wickeln kann und ebenfalls gezwungen wird, einen festgelegten Weg in Richtung auf den genannten Wickeldorn zu beschreiben. In der zweiten Position, in der die genannte Führung nicht an der genannten Klemmrolle anliegt, wodurch während des Wickelvorgangs, nachdem das Band mit dem Wickeldorn in Eingriff gebracht wurde und um den genannten Wickeldorn gewickelt wird, wird erreicht, daß unnötiger Verschleiß der Klemmrolle oder Riefenbildung auf der Oberfläche der Klemmrolle verhindert wird.The objects of the present invention are achieved by the winding system according to claim 1 and the winding method according to claim 9. In the first position, in which one end of said guide bears against one of said pinch rollers, it is achieved that the thin strip does not rise upwards can wrap around said pinch roller and also be forced to describe a fixed path in the direction of said winding mandrel. In the second position, in which said guide is not applied to said pinch roller, whereby during the winding operation, after the band has been engaged with the winding mandrel and wound around said winding mandrel, it is achieved that unnecessary wear of the pinch roller or scoring on the surface of the pinch roller is prevented.

In einer Vorteilhaften Ausführungsform umfaßt das erfindungsgemäße Wickelsystem eine Mehrzahl von Wickeldornen, wobei die Führung in eine dritte Position bewegt werden kann, in der die genannte Führung dem Band ermöglicht, einen anderen Weg zu einem anderen Wickeldorn zu beschreiben, während ein fertiger Bund auf einem anderen Dorn entnommen wird, wodurch die Produktivität des gesamten Wickelsystems gesteigert wird.In an advantageous embodiment, the winding system according to the invention comprises a plurality of winding mandrels, wherein the guide can be moved to a third position in which said guide allows the belt to describe another path to another winding mandrel while a finished bundle is on another Mandrel is removed, whereby the productivity of the entire winding system is increased.

Die Führung umfaßt eine Spitze aus einem nicht abrasiven, reibungsarmen Werkstoff wie etwa Micarta, so daß sie die Oberfläche der Klemmrolle nicht beschädigt. Die Führung wird als Reaktion auf ein Signal eines ersten, im vorgeschalteten Walzwerk angeordneten Sensors, daß eine neue Bramme gewalzt wird und daß sich das vordere Bandende den Klemmrollen nähert, automatisch in ihre ersten Position gebracht, in der sie an der Klemmrolle anliegt, und als Reaktion auf ein Signal eines zweiten, im nachgeschalteten Wickeldorn angeordneten Sensors, daß das Band um den genannten Dorn gewickelt wird, automatisch in ihre zweite Position in einem Abstand von der Klemmrolle gebracht.The guide comprises a tip of a non-abrasive, low-friction material such as micarta, so that it does not damage the surface of the pinch roller. The guide is automatically brought to its first position in which it bears against the pinch roller in response to a signal from a first sensor arranged in the upstream mill that a new slab is being rolled and that the front end of the band is approaching the pinch rollers In response to a signal from a second sensor arranged in the downstream winding mandrel that the tape is wound around said mandrel, it is automatically brought to its second position at a distance from the pinch roller.

In dieser Beschreibung und den beigefügten Zeichnungen werden einige bevorzugte Ausführungsformen der Erfindung gezeigt und beschrieben und verschiedene Alternativen und Modifikationen vorgeschlagen; es wird jedoch darauf hingewiesen, daß diese keinesfalls als erschöpfend anzusehen sind und daß zahlreiche Änderungen und Modifikationen innerhalb des Schutzbereichs der Erfindung möglich sind. Die hierin enthaltenen Vorschläge wurden zur Verdeutlichung ausgewählt und aufgenommen, damit andere Fachkundige die Erfindung und ihre Grundsätze besser verstehen können und somit in der Lage sind, sie in einer Vielzahl von Formen zu modifizieren, wie es jeweils für die Bedingungen des besonderen Anwendungszwecks am besten geeignet ist.In this description and the accompanying drawings, some preferred embodiments of the invention are shown and described and various alternatives and modifications are suggested; however, it should be understood that they are by no means exhaustive and that numerous changes and modifications are possible within the scope of the invention. The suggestions contained herein have been chosen and included for clarity so that others skilled in the art can and will better understand the invention and its principles are to modify them in a variety of forms, as it is most suitable for the conditions of the particular application purpose.

Abb. 1 ist ein schematischer Seitenaufriß einer bevorzugten Ausführungsform des Wickelsystems, der die Klappenführung in der ersten Position zeigt, in der sie an der Klemmrolle anliegt, um während des Einleitens des Wickelvorgangs ein unerwünschtes Anhaften des dünnen Stahlbands an der Klemmrolle und das Wickeln des dünnen Stahlbands um die Klemmrolle herum zu vermeiden.Fig. 1 is a schematic side elevational view of a preferred embodiment of the winding system showing the flap guide in the first position abutting the pinch roller to undesirably adhere the thin steel strip to the pinch roller and winding the thin strip during initiation of the winding operation Steel bands to avoid the pinch roller around.

Abb. 2 ist ein ähnlicher schematischer Seitenaufriß des Wickelsystems aus Abb. 1, wobei jedoch die Klappenführung in ihrer zweiten Position in einem Abstand von der Klemmrolle angeordnet ist, so daß ein kleiner Spalt verbleibt, damit ein unnötiger Verschleiß der Führung und der Klemmrolle während des laufenden Aufwickelns des Stahlbands (während dieses um den Wickeldorn gewickelt wird) zu vermeiden.Figure 2 is a similar schematic side elevational view of the winding system of Figure 1 but with the flap guide in its second position spaced from the pinch roller leaving a small gap to prevent unnecessary wear of the guide and pinch roller during operation ongoing winding of the steel strip (while this is wound around the winding mandrel) to avoid.

Abb. 3 ist eine schematische dreidimensionale Darstellung der Klappenführung und der damit verbundenen Klemmrollen (wobei die obere Klemmrolle zur größeren Klarheit der Abbildung nur als Durchsicht abgebildet ist).Fig. 3 is a schematic three-dimensional representation of the flap guide and the associated pinch rollers (the upper pinch roller being shown for clarity only).

Abb. 4 ist ein schematischer Seitenaufriß einer weiteren bevorzugten Ausführungsform eines Wickelsystems, das zwei Wickeldorne umfaßt, wobei die erste (vorgeschaltete) der beiden abgebildeten Klappenführungen in einer dritten Position abgebildet ist und die andere (nachgeschaltete) Klappenführung in der zweiten Position abgebildet ist, so daß das Stahlband über die erste Führung laufen und den ersten Wickeldorn umgehen kann, und wobei das Stahlband von der zweiten Klappenführung aufgenommen und nach unten zum Aufwickeln auf den zweiten Wickeldorn abgelenkt wurde.FIG. 4 is a schematic side elevational view of another preferred embodiment of a winding system including two mandrels wherein the first (upstream) of the two illustrated flap guides is shown in a third position and the other (downstream) flap guide is shown in the second position; that the steel strip can run over the first guide and can bypass the first winding mandrel, and wherein the steel strip was taken up by the second flap guide and deflected downwards for winding onto the second winding mandrel.

Abb. 5 ist ein schematischer Seitenaufriß eines Ausschnitts und zeigt eine Ausführungsform der Erfindung für den automatischen Betrieb der Klappenführung.Fig. 5 is a schematic side elevational view of a detail showing an embodiment of the invention for automatic operation of the flap guide.

Zwar wird die Erfindung im Einsatz in der Produktion und dem Aufwickeln von warmgewalzten Stahlband als einem der unmittelbaren Anwendungszwecke der Erfindung beschrieben, aber für den Fachkundigen ist offensichtlich, daß sie in ihren weitergehenden Aspekten in anderen ähnlichen Anwendungen bei industriellen Verfahren, beispielsweise in der Produktion von Aluminiumband, vorteilhaft genutzt werden kann.While the invention is described as being used in the production and winding of hot rolled steel strip as one of the immediate applications of the invention, it will be apparent to those skilled in the art that it will be considered in its broader aspects in other similar applications in industrial processes such as the production of Aluminum strip, can be used to advantage.

In Abbildungen 1, 2, 3, 4 und 5 sind verschiedene Ansichten des Wickelsystems abgebildet, wobei die gleichen Elemente in seinem Aufbau mit denselben Ziffern bezeichnet werden. Ziffer 10 kennzeichnet eine obere Klemmrolle, die mit einer unteren Klemmrolle 12 zusammenwirkt, um ein dünnes Stahlband 14 weiterzuziehen (z. B. zu einem Wickeldorn 16). Das Band läuft auf einem Ablaufrollgang oder einem Kühlrollgang 18. Das vordere Ende 28 des Bandes 14 wird von der Klappenführung 20 nach unten gedrückt, die an der Rolle 10 anliegt, so daß verhindert wird, daß sich das Band 14 aufgrund der hohen Geschwindigkeit nach oben um die Klemmrolle 10 wickelt. Das Teilstück 22 der Klappenführung 20, das an der Klemmrolle 10 anliegt, besteht vorzugsweise aus einem reibungsarmen, haltbaren Werkstoff, um Verschleiß und Riefenbildung auf der Oberfläche der Rolle 10 zu verhindern, und ist an der Klappenführung 20 durch geeignete herkömmliche Befestigungsmittel nach Stand der Technik befestigt. Zu diesem Zweck geeignete Werkstoffe für dieses Teilstück 22 sind "Micarta"-ähnliche Phenol- oder Melaminharz-Textilverbundstoffe. Die Klappenführung 20 ist durch geeignete Betätigungsmittel 26 um die Schwenkachse 24 beweglich, wobei es sich bei den Betätigungsmitteln 26 z. B. um einen Hydraulik- oder Pneumatikzylinder oder einen Nocken-Kurvenrollenmechanismus usw. handeln kann. Da die Spitze 22 der Klappenführung 20 an der Oberfläche der Rolle 10 anliegt, ohne daß ein Spalt zwischen beiden verbleibt, wird das vordere Ende 28 des Bandes 14 gezwungen, einen Weg zu beschreiben, der das Band 14 zum Dorn 16 führt. Der Weg des Bandes zum Wickeldorn 16 wird durch geeignete Führungsbleche 30 und 32 festgelegt.Figures 1, 2, 3, 4 and 5 show various views of the winding system, the same elements being denoted in their structure by the same numbers. Numeral 10 indicates an upper pinch roller which cooperates with a lower pinch roller 12 to advance a thin steel band 14 (e.g., to a winding mandrel 16). The tape runs on a run-down or a cold roller 18. The front end 28 of the tape 14 is pressed by the flap guide 20 down, which abuts the roller 10, so that is prevented that the tape 14 due to the high speed upwards wraps around the pinch roller 10. The portion 22 of the flap guide 20 which bears against the pinch roller 10 is preferably made of a low friction, durable material to prevent wear and scoring on the surface of the roller 10 and is attached to the flap guide 20 by any suitable conventional prior art fasteners attached. Suitable materials for this section 22 are "micarta" -like phenolic or melamine resin textile composites. The flap guide 20 is movable by suitable actuating means 26 about the pivot axis 24, wherein it is at the actuating means 26 z. B. may be a hydraulic or pneumatic cylinder or cam cam roller mechanism, etc. Since the top 22 of the Flap guide 20 abuts the surface of the roller 10, without leaving a gap between the two, the front end 28 of the belt 14 is forced to describe a path that guides the belt 14 to the mandrel 16. The path of the band to the winding mandrel 16 is determined by suitable guide plates 30 and 32.

Nachdem das vordere Ende 28 des Bandes 14 mit dem Dorn 16 in Eingriff gebracht und von diesem aufgenommen wurde und um diesen herum aufgewickelt wird, wird die Klappenführung 20 durch Betätigungsmittel 26 in eine zweite Position bewegt, wie in Abb. 2 dargestellt, in der das Teilstück 22 der genannten Führung nicht mehr an der Rolle 10 anliegt. Diese zweite Position ist die normale Betriebsposition der Führung während des eigentlichen Aufwickelns (um einerseits einen überhöhten Verschleiß der Rolle und der Führung zu vermeiden und andererseits die Kraft zu verringern, die für den Antrieb der oberen Klemmrolle erforderlich ist, während das Band aufgewickelt wird). Der Wickeldorn 16 ist mit Wickelrollen 34 versehen, die zur Bildung eines regelmäßigen spiralförmigen Bundes 36 um den Dorn 16 herum beitragen.After the leading end 28 of the belt 14 is engaged with and received by the mandrel 16 and is wound around it, the flap guide 20 is moved by actuating means 26 to a second position, as shown in Fig. 2, in which Section 22 of said guide is no longer applied to the roller 10. This second position is the normal operating position of the guide during actual winding (to avoid excessive wear of the roller and guide on the one hand and to reduce the force required to drive the upper pinch roller while the tape is being wound up). The winding mandrel 16 is provided with winding rollers 34 which contribute to the formation of a regular spiral collar 36 around the mandrel 16 around.

In Abb. 4 ist ein Wickelsystem dargestellt, das zwei hintereinander angeordnete Wickeleinrichtungen umfaßt. Die Klappenführung 20 ist so angepaßt, daß sie eine dritte Position einnehmen kann, in der sie eng an der unteren Klemmrolle 12 anliegt (nachdem die Bundbildung auf dem Dorn 16 abgeschlossen ist und durch das Durchschneiden des Bands 14 ein neues vorderes Ende 28 entsteht, damit der Dorn 48 als nächstes im Wechsel beschickt werden kann). Die reibungsarme Spitze 22 verhindert, daß sich das neue vordere Ende 28 um die Klemmrolle 12 wickelt. In dieser Position ermöglicht die Klappenführung dem Band 14 den weiteren Durchgang in Richtung auf die Klemmrollen 38 und 40, während die Klemmrolle 10 angehoben wurde, um einen freien Durchgang des Bandes 14 zu ermöglichen. Nachdem das neue vordere Ende 28 über die Klappenführung 20 (wie in Abbildung 4 dargestellt) gelaufen ist, wird die Spitze 22 von der Oberfläche der Rolle 12 angehoben und wieder in die gelöste zweite Position bewegt. Die Klappenführung 44 funktioniert auf die gleiche Weise wie die Klappenführung 20, um sicherzustellen, daß das neue vordere Ende 28 zwischen die Führungsbleche 64 und 66 abgelenkt wird und weiter zum entsprechenden zweiten Dorn 48 geführt wird. Danach wird die Klappenführung 44 (durch die Wirkung des Zylinders 68) in die zweite Position bewegt (wie in Abb. 4 dargestellt), während das Band 14 um den Dorn 48 aufgewickelt wird und in Verbindung mit den Wickelrollen 60 zu einem Bund 50 gewickelt wird.In Fig. 4, a winding system is shown, comprising two successively arranged winding devices. The flap guide 20 is adapted to assume a third position in which it bears snugly against the lower pinch roller 12 (after the cuffing is completed on the mandrel 16 and the cutting of the strap 14 results in a new front end 28 therewith the mandrel 48 can be loaded alternately next). The low-friction tip 22 prevents the new front end 28 from wrapping around the pinch roller 12. In this position, the flap guide allows the belt 14 to pass further towards the pinch rollers 38 and 40 while the pinch roller 10 has been raised to allow free passage of the belt 14. After the new front end 28 has passed over the flap guide 20 (as shown in Figure 4), the tip 22 will be off the surface the roller 12 is raised and moved back to the released second position. The flap guide 44 functions in the same manner as the flap guide 20 to ensure that the new front end 28 is deflected between the guide plates 64 and 66 and continues to the corresponding second mandrel 48. Thereafter, the flap guide 44 is moved (by the action of the cylinder 68) to the second position (as shown in FIG. 4) as the tape 14 is wound around the mandrel 48 and wound into a collar 50 in conjunction with the winding rolls 60 ,

In Abb. 5 ist schematisch eine Steuerung für die automatische Positionierung der Klappenführung 20 dargestellt. Der vorgeschaltet angeordnete Sensor 52 sendet ein Signal 53 an eine programmierbare Steuerung 54, daß sich ein vorderes Ende 28 des Bandes 14 in Richtung auf die Klemmrollen 10 und 12 bewegt. Das Stellglied 56, das von der Steuerung 54 angesteuert wird, reagiert auf das genannte Signal 53 und veranlaßt den Hydraulikzylinder 26, die Führung 20 in ihre erste Position zu bewegen, in der sie an der Rolle 10 anliegt. Sobald das Band 14 um den Dorn 16 gewickelt wird, sendet der Sensor 58 ein Signal 62 an die Steuerung 54, die dann das Stellglied 56 ansteuert, um den Zylinder 26 zu veranlassen, die Klappenführung 20 in die zweite Position zu bewegen (wodurch ein unnötig langer Kontakt des Kantenteilstücks 22 der Klappenführung 20 mit der Klemmrolle 10 vermieden wird).In Fig. 5, a control for the automatic positioning of the flap guide 20 is shown schematically. The upstream sensor 52 sends a signal 53 to a programmable controller 54 that a front end 28 of the belt 14 moves in the direction of the pinch rollers 10 and 12. The actuator 56, which is controlled by the controller 54, responsive to said signal 53 and causes the hydraulic cylinder 26 to move the guide 20 to its first position, in which it bears against the roller 10. Once the belt 14 is wrapped around the mandrel 16, the sensor 58 sends a signal 62 to the controller 54, which then drives the actuator 56 to cause the cylinder 26 to move the flap guide 20 to the second position (thereby eliminating unnecessary movement) long contact of the edge portion 22 of the flap guide 20 with the pinch roller 10 is avoided).

Es sollte klar sein, daß die hier beschriebenen Ausführungsformen der Erfindung nur zur Verdeutlichung dienen, und für den Fachkundigen ist offensichtlich, daß zahlreiche Änderungen an diesen Ausführungsformen vorgenommen werden, ohne den Schutzbereich der beanspruchten Erfindung zu verlassen.It should be understood that the embodiments of the invention described herein are for illustration only, and it will be apparent to those skilled in the art that numerous changes are made to these embodiments without departing from the scope of the claimed invention.
