Description

Die Erfindung betrifft eine Haspelvorrichtung zum Auf- und Abwickeln von bandförmigem Material auf eine bzw. von einer einen Einführschlitz für den Bandanfang aufweisenden Wickeltrommel.The invention relates to a reel device for winding and unwinding band-shaped material onto or from a winding drum having an insertion slot for the beginning of the band.

Bei einer aus der DE 43 21 606 A1 bekannten Haspelvorrichtung ist ein Wickeldorn zum Aufwickeln eines Blechbandes mit zahlreichen, radial verstellbaren Segmenten bestückt. Der Bandanfang wird zwischen zwei der radial spreizbaren Segmente geklemmt, deren Außenflächen die Wickeltrommel bilden. Um einen verlaufenden Übergang zwischen den Bandwindungen sicherzustellen, wird zwischen den beiden den Bandanfang aufnehmenden, unmittelbar aufeinerfolgenden Segmenten ein der Banddicke entsprechender Absatz vorgesehen, so daß die nachfolgenden Bandwindungen stufenlos über den Bandanfang gewickelt werden können. Damit sich beim Wickeln der nachfolgenden Bandwindungen eine sprunghafte Vergrößerung der Umfangsgeschwindigkeit und davon bewirkte erhebliche Zugspannungen vermeiden lassen, werden in der Spreizstellung des Haspeldornes die Segmente zwischen den beiden den Absatz bildenden Segmenten jeweils gegenüber den unmittelbar benachbarten Segmenten in gleichen Stufen versetzt; diese ergeben in der Summe die Absatzhöhe. Zum Ausgleich des radialen Stufensprunges sind die Segmente außerdem zwischen den einander zugekehrten axialen Rändern aufeinanderfolgenden Segmente in Drehrichtung des Haspeldorns für das Aufwickeln um eine dornparallele Achse geneigt.In a reel device known from DE 43 21 606 A1, a winding mandrel for winding a sheet metal strip is equipped with numerous, radially adjustable segments. The beginning of the tape is clamped between two of the radially expandable segments, the outer surfaces of which form the winding drum. In order to ensure a smooth transition between the tape turns, a paragraph corresponding to the tape thickness is provided between the two segments immediately following the tape, so that the subsequent tape turns can be wound continuously over the tape start. So that a sudden increase in the circumferential speed and considerable tensile stresses caused by it can be avoided when winding the subsequent strip windings, the segments between the two segments forming the shoulder are each offset in equal steps from the immediately adjacent segments in the spreading position of the reel mandrel; these add up to the total amount of sales. To compensate for the radial step change, the segments are also inclined between the mutually facing axial edges of successive segments in the direction of rotation of the reel mandrel for winding around an axis parallel to the mandrel.

Eine andere, durch die DE 37 36 857 A1 bekanntgewordene Haspelvorrichtung besitzt einen Wickeldorn, der zum Klemmen des Bandanfangs einen Klemmschlitz zwischen einer radial in einem Träger verstellbar geführten Klemmleiste und einem die Klemmleiste übergreifenden, verstellfest mit dem Träger verbundenen Gegenhalter aufweist. Auf der Klemmleiste stützt sich ein Mantelsegment mit seinem freien Ende in radialer Richtung federnd ab. Der Wickeldorn ist somit als Spreizdorn ausgebildet, bei dem auch der Träger mit dem Gegenhalter und dem federbelastenden Mantelsegment ein Spreizsegment darstellt. Beim Aufwickeln des Blechbandes ergibt sich ein Dickenausgleich, der von der Verstellung der übrigen Spreizsegmente über eine an dem Träger angreifende Spreizeinrichtung unabhängig bleibt. Die Außenflächen der Spreizsegmente und des Mantelsegmentes bilden auch hier wiederum die Wickeltrommel für das aufzuwickelnde Blechband.Another reel device which has become known from DE 37 36 857 A1 has a winding mandrel which, in order to clamp the beginning of the tape, has a clamping slot between a clamping strip which is guided in a radially adjustable manner in a carrier and a counter-holder which cross-connects the clamping strip and is fixedly connected to the carrier. A jacket segment is supported resiliently on the terminal strip with its free end in the radial direction. The winding mandrel is thus designed as an expanding mandrel, in which the carrier with the counter-holder and the spring-loaded jacket segment also represents an expanding segment. When the sheet metal strip is wound up, there is a thickness compensation which remains independent of the adjustment of the other spreading segments by means of a spreading device acting on the carrier. The outer surfaces of the spreading segments and the jacket segment again form the winding drum for the sheet metal strip to be wound up.

Mit diesen bekannten Haspelvorrichtungen soll die im Bereich der Klemmung des Bandanfangs entstehende Stufe beim Aufwickeln der zweiten und der folgenden Bandwindungen auf die erste Bandwindung ausgeglichen werden, indem ein allmählicher Übergang auf den größten Wickeldurchmesser der Wickeltrommel stattfindet. Diese bekannten Ausführungen sind allerdings von aufwendiger Bauweise, mechanisch sowie hydraulisch sehr komplex und daher entsprechend teuer. Außerdem erhöht der komplexe Aufbau die Störanfälligkeit und bedingt im Reparaturfall lange Stillstandszeiten der Haspelvorrichtung.These known reel devices are intended to compensate for the step occurring in the area of the clamping of the beginning of the tape when winding up the second and subsequent tape turns onto the first tape turn by a gradual transition to the largest winding diameter of the winding drum. However, these known designs are of complex construction, mechanically and hydraulically very complex and therefore correspondingly expensive. In addition, the complex structure increases the susceptibility to faults and causes long downtimes of the reel device in the event of repair.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Haspelvorrichtung der eingangs genannten Art zu schaffen, die mit einfachen Mitteln eine Klemmung des Bandanfangs ermöglicht.The invention is therefore based on the object of providing a reel device of the type mentioned at the outset which enables the strip start to be clamped with simple means.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß innerhalb der Wickeltrommel eine als Klemmhülse ausgebildete, in Umfangsrichtung bewegliche Welle angeordnet und mit mindestens einer Klemmwölbung versehen ist. Auf diese Weise läßt sich der Bandanfang einfach dadurch festlegen, daß er in den Einführschlitz der in der Einfädelposition in Ruhe befindlichen Wickeltrommel eingeführt und dann von der den Spalt zu der zylindrischen Innenwand der Wickeltrommel verengenden Klemmwölbung -hierunter wird in diesem Zusammenhang auch die sich aufgrund einer exzentrischen Anordnung der Klemmhülse in der Wickeltrommel einstellende Spaltverengung verstanden - erfaßt und zwischen der Innenwand der Wickeltrommel und der Klemmhülse festgeklemmt wird. Der sich bei dickerem Bandmaterial danach einstellende Reibschluß zwischen der Klemmhülse, dem Band und der Wickeltrommel bewirkt dann, daß auch die Wickeltrommel in Rotation versetzt und das eigentliche Aufwickeln der Bandwindungen - für die keinerlei Andrückmittel benötigt werden - auf den Außenmantel der Wickeltrommel einsetzt. Bei dieser - ersten - Ausführung macht die als Klemmhülse ausgebildete rotierende Welle innerhalb der Wickeltrommel volle Umdrehungen.This object is achieved in that a shaft designed as a clamping sleeve and movable in the circumferential direction is arranged within the winding drum and is provided with at least one clamping curvature. In this way, the beginning of the tape can be determined simply by placing it in the insertion slot in the Threading position of the winding drum at rest is introduced and then from the clamping curvature narrowing the gap to the cylindrical inner wall of the winding drum - including in this context the gap narrowing that occurs due to an eccentric arrangement of the clamping sleeve in the winding drum - is detected and between the inner wall of the winding drum and the clamping sleeve is clamped. The resulting frictional engagement between the clamping sleeve, the band and the winding drum then occurs in the case of thicker strip material, causing the winding drum to also rotate and the actual winding of the strip windings - for which no pressing means are required - to be used on the outer jacket of the winding drum. In this - first - version, the rotating shaft designed as a clamping sleeve makes full revolutions within the winding drum.

Eine bevorzugte Ausgestaltung der Erfindung sieht vor, daß die Klemmhülse im Querschnitt die Form eines Dreiecks mit konvexen Seiten aufweist. Durch diese dreieckige Außenform der rotierenden Klemmhülse verengt sich der Radialspalt zwischen der Klemmhülse und der zylindrischen Innenwand der Wickeltrommel pulsierend nach jeweils einer 120°-Drehung der Klemmhülse. Der Bandanfang wird folglich schon sehr schnell nach dem Einfädeln in den Einführschlitz von einer der drei Klemmwölbungen erfaßt und geklemmt.A preferred embodiment of the invention provides that the clamping sleeve has the shape of a triangle with convex sides in cross section. Due to this triangular outer shape of the rotating clamping sleeve, the radial gap between the clamping sleeve and the cylindrical inner wall of the winding drum pulsates after each 120 ° rotation of the clamping sleeve. As a result, the beginning of the tape is gripped and clamped very quickly after being threaded into the insertion slot by one of the three clamping arches.

Eine zweite Ausführung der Erfindung sieht vor, daß die Klemmhülse in Umfangsrichtung nur begrenzt in der Wickeltrommel rotieren kann. Der Erfindung liegt hierbei der Gedanke zugrunde, eine Bewegung der Klemmhülse durch die über den Außendurchmesser der Klemmhülse hervorspringende Klemmwölbung in Auf- und Abwickelrichtung der Wickeltrommel zu begrenzen, indem diese die Rotationsfreiheit der Klemmhülse einschränkt und somit neben der Klemmung eine weitere Funktion erfüllt. Aufgrund der damit auf eine Teilrotation beschränkten Bewegung der Klemmhülse läßt sich die Wickeltrommel in eine definierte Einfädelposition für den Bandanfang des zu wickelnden Bandmaterials bringen, die nämlich stets mit Sicherheit innerhalb der engen Bewegungsgrenzen liegt.A second embodiment of the invention provides that the clamping sleeve can only rotate in the circumferential direction to a limited extent in the winding drum. The invention is based on the idea of limiting movement of the clamping sleeve in the winding and unwinding direction of the winding drum by the clamping curvature projecting beyond the outer diameter of the clamping sleeve by restricting the freedom of rotation of the clamping sleeve and thus fulfilling a further function in addition to the clamping. Because of the movement of the clamping sleeve, which is thus limited to a partial rotation, the winding drum can be moved into a defined threading position for the beginning of the band of the winding Bring tape material, which is always with certainty within the narrow movement limits.

Nach einem Vorschlag der Erfindung ist dazu der Klemmwölbung im Innenmantel der Wickeltrommel eine Ausnehmung zugeordnet. Diese die Bewegungsgrenzen definierende Ausnehmung befindet sich im Bereich des Einführungsschlitzes; sie nimmt die Klemmwölbung auf, so daß sich die Klemmhülse lediglich innerhalb der Ausnehmung bewegen läßt. Wird die Klemmhülse jetzt entgegen der Aufwickelrichtung in Rotation versetzt, legt sich die Klemmwölbung mit einer Anschlagfläche an die in Drehrichtung liegende Stirnfläche der Ausnehmung an. Dadurch wird die Wickeltrommel mitgenommen und aus der Ausfädelposition punktgenau in die definierte Einfädelposition gedreht.According to a proposal of the invention, a recess is assigned to the clamping curvature in the inner jacket of the winding drum. This recess defining the movement limits is located in the area of the insertion slot; it takes up the clamping curvature so that the clamping sleeve can only be moved within the recess. If the clamping sleeve is now set in rotation against the winding direction, the clamping curvature rests with a stop surface on the end face of the recess lying in the direction of rotation. As a result, the winding drum is taken along and rotated from the threading position to the defined threading position with pinpoint accuracy.

Der Bandanfang des Bandmaterials läßt sich jetzt dadurch festlegen, daß er in dem vorteilhaft eine Klemmplatte - als leicht auszutauschendes Verschleißteil - aufweisenden Ausführungsschlitz der Wickeltrommel eingeschoben wird. Wenn die Klemmhülse in Aufwickelrichtung angetrieben wird, erfaßt sie nach einer kurzen Wegstrecke den Bandanfang und legt diesen zwischen der Klemmwölbung und der Klemmplatte fest. Während dieser Bewegung verbleibt die nach einer erfindungsgemäßen Ausgestaltung mit radialem Spiel in der Wickeltrommel angeordnete Klemmhülse so lange in der Einfädelposition, bis der Bandanfang geklemmt ist; danach wird die Wickeltrommel von der angetriebenen Klemmhülse zum Aufwickeln des Bandes mitgenommen.The beginning of the band of the band material can now be determined by inserting it into the execution slot of the winding drum, which advantageously has a clamping plate - as an easily replaceable wear part. If the clamping sleeve is driven in the winding direction, it detects the beginning of the tape after a short distance and sets it between the clamping arch and the clamping plate. During this movement, the clamping sleeve arranged according to an embodiment of the invention with radial play in the winding drum remains in the threading position until the beginning of the tape is clamped; then the winding drum is taken away by the driven clamping sleeve for winding the tape.

Nach einer Ausgestaltung der Erfindung ist die Klemmwölbung mit einer gegen die Aufwickelrichtung ansteigenden Keilfläche ausgebildet. Hierdurch wird eine allmähliche Verengung des Radialspaltes zwischen der Klemmhülse und der Klemmplatte des Einführungsschlitzes erreicht und der eingeschobene Bandanfang zur Mitnahme des Bandes schnell zwischen der Klemmwölbung und der Klemmplatte festgelegt, womit das eigentliche Aufwickeln der Bandwindungen auf den Außenmantel der Wickeltrommel eingeleitet wird.According to one embodiment of the invention, the clamping curvature is formed with a wedge surface that rises against the winding direction. In this way, a gradual narrowing of the radial gap between the clamping sleeve and the clamping plate of the insertion slot is achieved and the inserted tape start for taking the tape quickly between the clamping arch and the clamping plate, which initiates the actual winding of the tape turns on the outer jacket of the winding drum.

Eine weitere vorteilhafte Ausgestaltung der Erfindung sieht vor, die Wickeltrommel an ihrem Innenmantel mit umfangsverteilt angeordneten Stützflächen auszubilden. Diese Flächen bieten der von den zunehmenden Bandwindungen belasteten Wickeltrommel eine Abstützung an der Klemmhülse.A further advantageous embodiment of the invention provides for the winding drum to be formed on its inner jacket with supporting surfaces arranged around the circumference. These surfaces offer support to the clamping sleeve for the winding drum, which is subject to increasing winding windings.

Bei beiden beschriebenen Ausführungen ergeben sich beim Auflaufen der ersten Bandwindungen keine stufenartigen Deformationen an dem aufzuwickelnden Walz- bzw. Blechband. Es entstehen nämlich nur verhältnismäßig flach verlaufende, lediglich über einen Bruchteil der zu wickelnden Materialdicke ansteigende Unstetigkeitsstellen, die schon nach wenigen Bandwindungen selbsttätig ausgeglichen sind. Zum Wickeln der Bandwindungen müssen die Wickeltrommeln nicht erst noch, wie bei bekannten Haspelanlagen unumgänglich, auf Wickelgeschwindigkeit hochgefahren werden.In both versions described, there are no step-like deformations on the rolled or sheet metal strip to be wound when the first strip windings run up. This is because there are only relatively flat discontinuities which only increase over a fraction of the material thickness to be wound and which are automatically compensated for after only a few turns of the strip. In order to wind the strip windings, the winding drums do not first have to be run up to the winding speed, as is unavoidable in known reel plants.

Nach einem Vorschlag der Erfindung ist den Klemmhülsen ein regelbarer Antrieb zugeordnet. Dieser ermöglicht es die Umfangsgeschwindigkeit der innerhalb der Wickeltrommel rotierenden Klemmhülse an die Geschwindigkeit anzupassen, mit der der Bandanfang durch den Einführungsschlitz der Wickeltrommel in den sich periodisch verengenden Radialspalt eingeschoben wird. Das Synchronisieren der Geschwindigkeiten erlaubt eine sanfte und ruckfreie Klemmung des Bandanfangs. Bei der nur begrenzt innerhalb der Wickeltrommel rotierenden Klemmhülse ermöglicht der regelbare Antrieb eine geringe Anlaufgeschwindigkeit der Klemmhülse zum Klemmen des Bandanfangs, die sich nach erfolgter Klemmung an die Vorschubgeschwindigkeit anpassen läßt, mit der das aufzuwickelnde Band zur Wickeltrommel hin transportiert wird. Weiterhin dient der regelbare Antrieb dazu, die Umfangsgeschwindigkeit der Wickeltrommel an die jeweilige Dicke des aufzuwickelnden bandförmigen Materials anzupassen.According to a proposal of the invention, a controllable drive is assigned to the clamping sleeves. This makes it possible to adapt the peripheral speed of the clamping sleeve rotating within the winding drum to the speed at which the beginning of the tape is inserted through the insertion slot of the winding drum into the periodically narrowing radial gap. The synchronization of the speeds allows a gentle and jerk-free clamping of the beginning of the tape. With the clamping sleeve rotating only to a limited extent within the winding drum, the controllable drive enables a low start-up speed of the clamping sleeve for clamping the beginning of the tape, which can be adjusted after the clamping to the feed speed with which the tape to be wound is transported to the winding drum. Furthermore, the adjustable drive serves to adapt the peripheral speed of the winding drum to the respective thickness of the band-shaped material to be wound up.

Wenn der regelbare Antrieb der Klemmhülsen vorzugsweise reversierbar ist, läßt sich bei umgekehrter Drehrichtung der Wickeltrommeln das Bandmaterial auch abwickeln. Sobald das Band soweit abgewickelt ist, daß keine Windung mehr auf dem Außenmantel der Wickeltrommeln liegt, wird das Bandende - bedingt durch den Bandzug und den Drehsinn der Hülse - selbsttätig freigegeben. Bei der nur begrenzt rotierenden Klemmhülse wird nach der selbsttätigen Freigabe des Bandendes die Wickeltrommel - wie eingangs beschrieben - über die Klemmwölbung der Klemmhülse punktgenau in die definierte Einfädelposition gedreht.If the controllable drive of the clamping sleeves is preferably reversible, this can be done in the opposite direction of rotation of the winding drums Also unwind tape material. As soon as the tape has been unwound to such an extent that there is no more winding on the outer jacket of the winding drums, the tape end is automatically released due to the tape tension and the direction of rotation of the sleeve. In the case of the clamping sleeve, which only rotates to a limited extent, after the automatic release of the tape end, the winding drum - as described at the beginning - is precisely rotated into the defined threading position via the clamping curvature of the clamping sleeve.

Bei der in Figur 1 dargestellten Haspelvorrichtung 1 für Walzband 2 wird der Bandanfang 3 des Walzbandes 2 in üblicher Weise mittels eines Treibers 4 in eine Bandleitvorrichtung 5 abgelenkt. Diese erstreckt sich von dem Treiber 4 nach oben gerichtet zu einer Wickeltrommel 7 hin; sie ist entsprechend dem zu- bzw. abnehmenden Bunddurchmesser nachstellbar. Im Inneren der Wickeltrommel 7 ist eine mit einer Klemmhülse 8 ausgebildete rotierende Welle 9 angeordnet. Diese weist im Ausführungsbeispiel nach Figur 1 eine Klemmwölbung 10 auf, die den Radialspalt 11 zwischen der Innenwand 12 und der Klemmhülse 8 entsprechend seinem Vorsprungmaß exzenterartig verengt, das an die Dicke des aufzuwickelnden Walzbandes angepaßt ist. Die Bandleitvorrichtung 2 ist auf einen Einführschlitz 13 der in der Einfädelposition in Ruhe befindlichen Wickeltrommel 7 gerichtet, und der Bandanfang 3 des von dem Treiber 4 gemäß Pfeil 15 vorgeschobenen Walzbandes 2 wird über den Einführschlitz 13 folglich in den Raum zwischen der Wickeltrommel 7 und der darin konzentrisch angeordneten Klemmhülse 8 eingeschoben. Sobald die Klemmwölbung 10 der in der Pfeilrichtung 14 rotierenden Klemmhülse 8 den Einführschlitz 13 passiert hat, wird der Bandanfang 3 des aufzuwickelnden Walzbandes 3 erfaßt und aufgrund des in diesem Bereich verengten Radialspaltes 11 zwischen der Innenwand 12 der Wickeltrommel 7 und der Klemmwölbung 10 geklemmt.In the reel device 1 for rolled strip shown in FIG. 1 2, the beginning of the strip 3 of the rolled strip 2 is deflected in a conventional manner into a strip guide device 5 by means of a driver 4. This extends from the driver 4 upwards to a winding drum 7; it can be adjusted according to the increasing or decreasing collar diameter. A rotating shaft 9 formed with a clamping sleeve 8 is arranged in the interior of the winding drum 7. In the exemplary embodiment according to FIG. 1, this has a clamping curvature 10 which narrows the radial gap 11 between the inner wall 12 and the clamping sleeve 8 in an eccentric manner, which is adapted to the thickness of the rolled strip to be wound up. The strip guide device 2 is directed towards an insertion slot 13 of the winding drum 7 which is at rest in the threading position, and the beginning of the strip 3 of the rolled strip 2 advanced by the driver 4 according to arrow 15 is consequently via the insertion slot 13 into the space between the winding drum 7 and therein concentrically arranged clamping sleeve 8 inserted. As soon as the clamping curvature 10 of the clamping sleeve 8 rotating in the direction of the arrow 14 has passed the insertion slot 13, the beginning of the strip 3 of the rolled strip 3 to be wound is detected and clamped between the inner wall 12 of the winding drum 7 and the clamping curvature 10 due to the narrowed radial gap 11 in this area.

Das Einfädeln und Aufwickeln des im Ausführungsbeispiel dicken Walzbandes 2 wird nachfolgend anhand der in Figuren 2a bis 2c gezeigten Phasenbilder im einzelnen erläutert. In der in Figur 2a gezeigten Einfädelposition befindet sich die Wickeltrommel 7 in einer Ruhelage und ist mit ihrem Einführschlitz 13 axial zum Bandanfang 3 des aufzuwickelnden Walzbandes 2 ausgerichtet, das in Pfeilrichtung 15 eingeschoben wird. Die von einem als gestrichelte Black-Box schematisch gekennzeichnenden Antrieb 16 in Pfeilrichtung 14 angetriebene Klemmhülse 108 weist bei dieser Ausführung die Form eines Dreiecks mit konvexen Seiten 17 auf, das heißt sie besitzt drei Klemmwölbungen 110a, 110b und 110c.The threading and winding of the rolled strip 2, which is thick in the exemplary embodiment, is explained in detail below with reference to the phase images shown in FIGS. 2a to 2c. In the threading position shown in FIG. 2a, the winding drum 7 is in a rest position and is aligned with its insertion slot 13 axially to the start of the strip 3 of the rolled strip 2 to be wound, which is inserted in the direction of the arrow 15. In this embodiment, the clamping sleeve 108, driven schematically in the direction of arrow 14 by a drive 16 schematically identified as a dashed black box, has the shape of a triangle with convex sides 17, that is to say it has three clamping curvatures 110a, 110b and 110c.

Der Bandanfang 3 schiebt sich mittels Bandvorschub (Treiber 4) in Pfeilrichtung 15 axial in den Einführschlitz 13 der Wickeltrommel 7. Durch den sich aufgrund der Klemmwölbungen 110a bis 110c periodisch verengenden Radialspalt 11 zwischen der rotierenden Klemmhülse 108 und der zylindrischen Innenwand 12 der Wickeltrommel 7 wird der Bandanfang 3 zwischen einer der drei Klemmwölbungen 110a bis 110c und der zylindrischen Innenwand 12 geklemmt; gemäß Figur 2b ist es die Klemmwölbung 110b, die den Bandanfang 3 erfaßt und zunehmend festlegt, bis er dann vollständig geklemmt ist. Einhergehend mit der zunehmenden Klemmung stellt sich ein Reibschluß zwischen der Klemmhülse 108, dem Bandanfang 3 bzw. dem Walzband 2 und der Wickeltrommel 7 ein; dieser bewirkt, daß auch die Wickeltrommel 7 in Rotation versetzt und das eigentliche Aufwickeln eingeleitet wird. Durch die gemäß Figur 2c gemeinsame Rotation von Wickeltrommel 7 und Klemmhülse 108 in Pfeilrichtung 18 wickeln sich die Bandwindungen 19 auf den Außenmantel 20 der Wickeltrommel 7 auf; gemäß Figur 2c befinden sich zwei Bandwindungen 19 auf der Wickeltrommel 7.The beginning of the band 3 is pushed axially into the insertion slot 13 of the winding drum 7 in the direction of the arrow 15 by means of the band feed (driver 4). Due to the periodically narrowing radial gap 11 between the rotating clamping sleeve 108 and the cylindrical inner wall 12 of the winding drum 7 due to the clamping bulges 110a to 110c the beginning of the band 3 is clamped between one of the three clamping domes 110a to 110c and the cylindrical inner wall 12; According to FIG. 2b, it is the clamping curvature 110b which detects and increasingly determines the beginning of the band 3 until it is then completely clamped. Along with the increasing clamping there is a frictional engagement between the clamping sleeve 108, the beginning of the strip 3 or the rolled strip 2 and the winding drum 7; this has the effect that the winding drum 7 is also set in rotation and the actual winding is initiated. As a result of the common rotation of winding drum 7 and clamping sleeve 108 in the direction of arrow 18 according to FIG. 2c, the band windings 19 wind up on the outer jacket 20 of the winding drum 7; According to FIG. 2 c, there are two band windings 19 on the winding drum 7.

Wie sich aus den Figuren 2b und 2c entnehmen läßt, ragt der Bandanfang 3 des Walzbandes 2 ein gewisses Maß über einen nasenförmigen Ansatz 21 im Bereich des Einführschlitzes 13 der Wickeltrommel 7 hinaus. Beim Auflaufen der ersten Bandwindungen 19 entstehen keine Stufensprünge, sondern nur verhältnismäßig flach verlaufende, lediglich über einen Bruchteil der zu wickelnden Materialdicke ansteigende Unstetigkeitstellen, die aber schon nach wenigen Bandwindungen 18 nicht mehr auftreten.As can be seen from FIGS. 2b and 2c, the strip beginning 3 of the rolled strip 2 protrudes to a certain extent beyond a nose-shaped extension 21 in the region of the insertion slot 13 of the winding drum 7. When the first band windings 19 run up, there are no step changes, but only relatively flat running discontinuities which only increase over a fraction of the material thickness to be wound, but which no longer occur after a few band windings 18.

Zum Abwickeln des Walzbandes 2 wird die Drehrichtung des Antriebs 16 umgekehrt, und die Wickeltrommel 7 sowie die Klemmhülse 108 rotieren folglich in gemäß Pfeil 22 nach Figur 3 umgekehrter Richtung. Nach Figur 3, ist das Walzband 2 vollständig von dem Außenmantel 20 der Wickeltrommel 7 abgewickelt und die Wickeltrommel 7 in der Einfädelposition abgebremst worden, in der sie zu einem neuerlichen Wickelvorgang verbleibt. Gleichwohl wird der Bandanfang 2, der beim Abwickeln das Bandende darstellt, selbsttätig freigegeben, nämlich bedingt durch einen auf das Walzband 3 einwirkenden Bandzug (vgl. den Pfeil 23) im Zusammenspiel mit der Rotation der Klemmhülse 108 und der Wickeltrommel 7 in Pfeilrichtung 22.To unwind the rolled strip 2, the direction of rotation of the drive 16 is reversed, and the winding drum 7 and the clamping sleeve 108 consequently rotate in the opposite direction according to arrow 22 in FIG. 3. According to FIG. 3, the rolled strip 2 has been completely unwound from the outer jacket 20 of the winding drum 7 and the winding drum 7 has been braked in the threading position in which it becomes one another winding process remains. Nevertheless, the beginning of the strip 2, which represents the end of the strip during unwinding, is released automatically, namely due to a strip tension acting on the rolled strip 3 (see arrow 23) in conjunction with the rotation of the clamping sleeve 108 and the winding drum 7 in the direction of the arrow 22.

Bei der in den Figuren 4a bis 4c dargestellten Wickeltrommel 207 ist im Inneren der Wickeltrommel 207 eine mit einer Klemmhülse 208 ausgebildete, in Umfangsrichtung begrenzt rotierende Welle 209 mit radialem Spiel angeordnet. Diese weist eine als Keil ausgebildete Klemmwölbung 210 auf, die an ihrem der Aufwickelrichtung 24 abgewandten Ende 25 eine Anschlagfläche 26 besitzt und mit einer gegen die Aufwickelrichtung 24 ansteigenden Keilfläche 27 ausgebildet ist. Der Klemmwölbung 210 ist im Innenmantel 28 der Wickeltrommel 207 eine Ausnehmung 29 zugeordnet. Die Ausnehmung 29 liegt im Bereich des Einführungsschlitzes 30, der mit einer Klemmplatte 31 ausgebildet ist. Des weiteren ist der Innenmantel 28 mit umfangsverteilt angeordneten Stützflächen 32a bis 32d ausgebildet.In the winding drum 207 shown in FIGS. 4a to 4c, a shaft 209 formed with a clamping sleeve 208 and rotating to a limited extent in the circumferential direction is arranged inside the winding drum 207 with radial play. This has a clamping curvature 210 designed as a wedge, which has an abutment surface 26 at its end 25 facing away from the winding direction 24 and is designed with a wedge surface 27 rising towards the winding direction 24. A recess 29 is assigned to the clamping curvature 210 in the inner jacket 28 of the winding drum 207. The recess 29 lies in the region of the insertion slot 30, which is formed with a clamping plate 31. Furthermore, the inner jacket 28 is formed with support surfaces 32a to 32d arranged circumferentially distributed.

Das Einfädeln und Aufwickeln des bei dieser Ausführung aufzuwickelnden dünnen Walzbandes wird nachfolgend anhand der in den Figuren 4a bis 4c gezeigten Phasenbilder im einzelnen erläutert:The threading and winding of the thin rolled strip to be wound up in this embodiment is explained in detail below using the phase images shown in FIGS. 4a to 4c:

In der in Figur 4a gezeigten Einfädelposition befindet sich die Wickeltrommel 207 in einer Ruhelage und ist mit ihrem Einführungsschlitz 30 zum Bandanfang 33 des aufzuwickelnden Walzbandes 34 ausgerichtet. Der Bandanfang 33 ist mittels Bandvorschub, z. B. durch einen hier nicht gezeigten Treiber, in Pfeilrichtung 35 in den Einführungsschlitz 30 bis zum Ende der Klemmplatte 31 eingeschoben worden. Die von einem als gestrichelte Black-Box schematisch gekennzeichneten Antrieb 16 antreibbare Klemmhülse 208 befindet sich in ihrer Grundstellung. Die Klemmwölbung 210 liegt über ihre Anschlagfläche 26 an der ihr zugewandten Stirnseite 36 der Ausnehmung 29 an.In the threading position shown in FIG. 4a, the winding drum 207 is in a rest position and is aligned with its insertion slot 30 to the strip start 33 of the rolled strip 34 to be wound up. The beginning of the tape 33 is by means of tape feed, for. B. by a driver, not shown here, in the direction of arrow 35 in the insertion slot 30 to the end of the clamping plate 31. The clamping sleeve 208, which can be driven by a drive 16 schematically identified as a dashed black box, is in its basic position. The clamping curvature 210 lies against its end face 26 on the end face 36 of the recess 29 facing it.

Gemäß Figur 4b wird die Klemmhülse 208 über den Antrieb 16 in Aufwickelrichtung 24 in Rotation versetzt. Durch die gegen die Aufwickelrichtung 24 ansteigende Keilfläche 27 verringert sich der Radialspalt 37 zwischen der Klemmhülse 208 und der Klemmplatte 31 des Einführungsschlitzes 30; der Bandanfang 33 wird zwischen der Klemmwölbung 210 und der Klemmplatte 31 geklemmt. Nach erfolgter Klemmung stellt sich ein Formschluß zwischen der Keilfläche 27 der Klemmwölbung 210, dem Bandanfang 33 und der Klemmplatte 31 ein; dieser bewirkt, daß auch die Wickeltrommel 207 in Rotation versetzt und das eigentliche Aufwickeln eingeleitet wird.According to FIG. 4b, the clamping sleeve 208 is set in rotation via the drive 16 in the winding direction 24. Due to the wedge surface 27 rising towards the winding direction 24, the radial gap 37 between the clamping sleeve 208 and the clamping plate 31 of the insertion slot 30 is reduced; the beginning of the band 33 is clamped between the clamping arch 210 and the clamping plate 31. After clamping, a positive connection between the wedge surface 27 of the clamping arch 210, the beginning of the band 33 and the clamping plate 31; this has the effect that the winding drum 207 is also set in rotation and the actual winding is initiated.

Durch die gem. Figur 4c gemeinsame Rotation von Wickeltrommel 207 und Klemmhülse 208 in Aufwickelrichtung 24 wickeln sich die Bandwindungen 38 auf den Außenmantel 39 der Wickeltrommel 207 auf. Dabei wird durch die zunehmenden Bandwindungen 38 eine gewisse Kraft auf die Wickeltrommel 207 ausgeübt; diese kann sich über Stützflächen 32a bis 32d an die Klemmhülse 208 anlegen. Die Ausnehmungen 40a bis 40c am Innenmantel 28 der Wickeltrommel 207 begünstigen eine gleichmäßige radiale Abstützung der Wickeltrommel 207 an der Klemmhülse 208.Due to the Figure 4c common rotation of winding drum 207 and clamping sleeve 208 in the winding direction 24, the tape turns 38 wind up on the outer jacket 39 of the winding drum 207. A certain force is exerted on the winding drum 207 by the increasing band windings 38; this can rest against the clamping sleeve 208 via support surfaces 32a to 32d. The recesses 40a to 40c on the inner jacket 28 of the winding drum 207 promote uniform radial support of the winding drum 207 on the clamping sleeve 208.

Zum Abwickeln des Walzbandes 34 wird die Drehrichtung des Antriebes 16 umgekehrt, und die Wickeltrommel 207 sowie die Klemmhülse 208 rotieren folglich in gemäß Pfeil 41 nach Figur 5 umgekehrter Richtung. Nach Figur 5 ist das Walzband 35 vollständig von dem Außenmantel 39 der Wickeltrommel 207 abgewickelt. Der Bandanfang 33 wird durch die Keilfläche 27 der Klemmwölbung 206 freigegeben, und da die Wickeltrommel 207 von der an der Stirnfläche 36 der Ausnehmung 29 anliegenden Anschlagfläche 26 der Klemmwölbung 210 beaufschlagt wird, läßt sich die Wickeltrommel 207 in die in Figur 4a gezeigte, definierte Einfädelposition drehen, in der sie zu einem neuerlichen Wickelvorgang bereit ist. Gleichzeitig wird der Bandanfang 33, der beim Abwickeln das Bandende darstellt, selbsttätig freigegeben und kann durch einen auf das Walzband 24 einwirkenden Bandzug (vergl. den Pfeil 42) im Zusammenspiel mit der Rotation der Klemmhülse 208 und der Wickeltrommel 207 in Pfeilrichtung 41 abgewickelt werden.To unwind the rolled strip 34, the direction of rotation of the drive 16 is reversed, and the winding drum 207 and the clamping sleeve 208 consequently rotate in the opposite direction according to arrow 41 in FIG. According to FIG. 5, the rolled strip 35 is completely unwound from the outer jacket 39 of the winding drum 207. The beginning of the tape 33 is released by the wedge surface 27 of the clamping arch 206, and since the winding drum 207 is acted upon by the abutment surface 26 of the clamping arch 210 resting on the end face 36 of the recess 29, the winding drum 207 can be moved into the defined threading position shown in FIG. 4a turn in which it is ready for a new winding process. At the same time, the beginning of the strip 33, which is the end of the strip during unwinding, is automatically released and can be pulled by a strip tension acting on the rolled strip 24 arrow 42) in cooperation with the rotation of the clamping sleeve 208 and the winding drum 207 in the direction of arrow 41.
