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, wobei innerhalb der Wickeltrommel eine als Klemmhülse ausgebildete, rotierende bzw. in Umfangsrichtung bewegliche Welle angeordnet und mit mindestens einer Klemmwölbung versehen ist.The invention relates to a reel device for winding and unwinding of band-shaped material on or from an insertion slot for the winding drum having the beginning of the tape, being inside the winding drum is designed as a rotating rotating sleeve or arranged in the circumferential direction shaft and with at least one clamping curvature is provided.

Eine solche Haspelvorrichtung ist durch die DE 437 972 C bekanntgeworden. Die rotierende Antriebswelle mit einer darauf angeordneten Innentrommel nimmt nach dem Klemmen des Bandes zwischen dieser Innentrommel und einer äußeren Wickeltrommel in der Folge das zu wickelnde Band mit.Such a reel device has become known from DE 437 972 C. The rotating drive shaft with one arranged on it The inner drum takes after the band is clamped between them Inner drum and an outer winding drum as a result winding band with.

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 with numerous radially adjustable segments. The beginning of the band is between two of the radially expandable segments are clamped, their outer surfaces form the winding drum. A smooth transition ensuring between the tape turns will be between the two the segments that take up the beginning of the tape and immediately follow one another a paragraph corresponding to the strip thickness is provided so that the subsequent winding turns continuously over the beginning of the tape can be. So that when winding the subsequent tape turns a sudden increase in peripheral speed and considerable tensile stresses caused thereby can be avoided in the spreading position of the reel mandrel, the segments between the the two segments forming the sales in each case compared to the immediate adjacent segments offset in equal steps; this result in the total of the sales height. To compensate for the radial The segments are also incremental between each other facing axial edges of successive segments in the direction of rotation of the reel mandrel for winding around a parallel mandrel Axis inclined.

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 known from DE 37 36 857 A1 has a winding mandrel that clamps the start of the tape a clamping slot between a radially adjustable in a carrier guided terminal strip and a cross-over the terminal strip, has adjustable counterholders connected to the carrier. On the terminal block is supported by a jacket segment with its free end resilient in the radial direction. The mandrel is therefore as Spreader mandrel formed, in which the carrier with the counterholder and the spring-loaded jacket segment represents an expansion segment. When winding up the sheet metal strip, there is a thickness compensation, of the adjustment of the remaining spreading segments via one on the Spreader attacking the carrier remains independent. The outside surfaces the spreading segments and the jacket segment also form here again 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.With these known reel devices in the area of Clamping of the beginning of the tape is created when winding the second and the following tape turns on the first tape turn be balanced by a gradual transition to the largest Winding diameter of the winding drum takes place. These well-known However, designs are of complex construction, mechanical as well as hydraulically very complex and therefore correspondingly expensive. Moreover the complex structure increases the susceptibility to faults and causes in Repairs long downtimes of the reel device.

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 a reel device of the type mentioned at the beginning with simple Means a clamping of the beginning of the tape allows.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, 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.This object is achieved in that the clamping sleeve in cross-section the shape of a triangle with convex sides having. 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 pulsating after each a 120 ° turn of the clamping sleeve. The beginning of the band is consequently very quickly after threading into the insertion slot of one of the three clamping arches is gripped and clamped.

Eine zweite Ausführung der Erfindung weist die im kennzeichnenden Teil des Anspruch 4 enthaltenen Merkmale auf. 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, die nur begrenzt in der Wickeltrommel rotieren kann, 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 has the characteristic Features contained in part of claim 4. The invention lies here the idea is based on a movement of the clamping sleeve the projecting over the outer diameter of the ferrule Clamping curvature in the winding and unwinding direction of the winding drum limit by restricting the freedom of rotation of the clamping sleeve and thus fulfills another function in addition to the clamping. Due to the limited movement of the Clamping sleeve, which can only rotate in the winding drum to a limited extent, the winding drum can be in a defined threading position for bring the beginning of the tape to be wound, namely the always with certainty within the narrow movement limits.

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. This recess defining the limits of movement is located in the area of the insertion slot; it takes up the clamping curvature, so that the clamping sleeve is only inside the recess can move. The clamping sleeve is now opposite to the winding direction set in rotation, the clamping curvature settles with a Stop face on the end face of the in the direction of rotation Recess. This will take the winding drum with you and out the threading position precisely in the defined threading position turned.

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 tape material can now be determined by that he in the advantageous a clamping plate - as easy to replace Wear part - having execution slot of the Winding drum is inserted. If the clamping sleeve in the winding direction is driven, it detects after a short distance the beginning of the tape and places it between the clamping curve and the Clamping plate firmly. During this movement, it remains after one Design according to the invention with radial play in the winding drum arranged clamping sleeve in the threading position, until the beginning of the tape is clamped; then the winding drum from 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 included a wedge surface rising against the winding direction. This causes a gradual narrowing of the radial gap between the clamping sleeve and the clamping plate of the insertion slot reached and the inserted band start to take the band quickly fixed between the clamping arch and the clamping plate, with which the actual winding of the tape turns on the outer jacket the winding drum is initiated.

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.Another advantageous embodiment of the invention provides the winding drum arranged on its inner jacket with circumferentially distributed Form support surfaces. These areas are offered by the increasing winding windings loaded a support on the clamping sleeve.

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, this results in the emergence no step-like deformations on the first tape windings roll or sheet metal strip to be wound up. It only happens relatively flat, only over a fraction the discontinuities increasing the material thickness to be wound, which are automatically balanced after just a few turns of the belt. The winding drums do not have to be used to wind the tape turns nor, as inevitable in known reel plants, on winding speed be started up.

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, the clamping sleeves are adjustable Drive assigned. This enables the peripheral speed of the clamping sleeve rotating within the winding drum adjust the speed at which the beginning of the tape through the Insertion slot of the winding drum in the periodically narrowing Radial gap is inserted. Synchronizing the Speeds allows a smooth and jerk-free clamping of the Band beginning. With only limited within the winding drum rotating clamping sleeve, the adjustable drive enables a low Starting speed of the clamping sleeve for clamping the beginning of the tape, which, after clamping, is adjusted to the feed rate can be adjusted with which the tape to be wound up to the winding drum is transported there. The adjustable drive also serves to the peripheral speed of the winding drum to the respective thickness to adapt 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 is, can with the reverse direction of rotation of the winding drums Also unwind tape material. As soon as the tape has been unwound, that there is no more winding on the outer jacket of the winding drums, becomes the end of the strip - due to the strip tension and the direction of rotation of the Sleeve - released automatically. With the rotating only limited The clamping sleeve becomes the after the automatic release of the tape end Winding drum - as described at the beginning - over the clamping arch the clamping sleeve turned precisely into the defined threading position.

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 5 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 is the beginning of the strip 3 of the rolled strip 2 in the usual way a driver 4 deflected into a tape guide device 5. This extends upward from driver 4 to one Winding drum 7 out; it is corresponding to the increasing or decreasing Adjustable collar diameter. Inside the winding drum 7 is a rotating shaft 9 formed with a clamping sleeve 8 is arranged. In the exemplary embodiment according to FIG. 1, this has a clamping curvature 10 on the radial gap 11 between the inner wall 12th and the clamping sleeve 8 eccentrically in accordance with its projection dimension narrowed, which is adapted to the thickness of the rolled strip is. The tape guide device 5 is on an insertion slot 13 directed in the threading position at rest winding drum 7, and the beginning of the tape 3 by the driver 4 according to arrow 15 advanced roll strip 2 is consequently via the insertion slot 13 in the space between the winding drum 7 and the concentric therein arranged clamping sleeve 8 inserted. As soon as the clamping curvature 10 the clamping sleeve 8 rotating in the direction of the arrow 14 has the insertion slot 13 has happened, the beginning of the tape 3 of the winding Rolling strip 3 detected and due to the narrowing in this area Radial gap 11 between the inner wall 12 of the winding drum 7 and the clamping arch 10 clamped.

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 thick in the embodiment Rolling strip 2 is subsequently based on that in FIGS. 2a to 2c shown phase images explained in detail. In the figure 2a shown threading position is the winding drum 7 in a rest position and is with its insertion slot 13 axially to the beginning of the tape 3 of the rolled strip 2 to be wound, which in Arrow direction 15 is inserted. The one with a dashed line Black box schematically identifying drive 16 in the direction of the arrow 14 driven clamping sleeve 108 has the shape in this embodiment of a triangle with convex sides 17, that is, it has three clamping domes 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 tape 3 is pushed in by means of the tape feed (driver 4) Direction of arrow 15 axially into the insertion slot 13 of the winding drum 7. By periodically due to the clamping bulges 110a to 110c narrowing radial gap 11 between the rotating clamping sleeve 108 and the cylindrical inner wall 12 of the winding drum 7 the beginning of the band 3 between one of the three clamping arches 110a to 110c and the cylindrical inner wall 12 clamped; according to figure 2b, it is the clamping curvature 110b which detects the beginning 3 of the tape and increasingly sets until it is completely clamped. Accompanying with increasing clamping there is a frictional connection between the clamping sleeve 108, the beginning of the strip 3 or the rolled strip 2 and the winding drum 7; this also causes the winding drum 7 set in rotation and the actual winding started becomes. Due to the common rotation of the winding drum according to FIG. 2c 7 and clamping sleeve 108 in the direction of arrow 18 wind the tape turns 19 on the outer jacket 20 of the winding drum 7; according to Figure 2c are two tape turns 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 beginning of the tape protrudes 3 of the rolled strip 2 a certain amount over a nose-shaped Approach 21 in the area of the insertion slot 13 of the winding drum 7 out. When the first band windings 19 run up, none occur Increments, but only relatively flat, only over a fraction of the material thickness to be wound increasing points of discontinuity, but after just a few tape turns 18 no longer occur.

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 vice versa, 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 Figure 3, the rolled strip 2 is completely from the outer jacket 20 of the winding drum 7 and the winding drum 7 slowed down in the threading position in which it becomes a another winding process remains. Nevertheless, the beginning of the band 2, which represents the end of the tape when unwinding, released automatically, namely due to one acting on the rolled strip 3 Belt tension (see arrow 23) in interaction with the rotation of the Clamping sleeve 108 and the winding drum 7 in the direction of 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 is inside the winding drum 207 with a ferrule 208 trained, limited rotating shaft 209 in the circumferential direction radial play arranged. This has a wedge Clamping curvature 210 on that facing away from the winding direction 24 End 25 has a stop surface 26 and with one against the winding direction 24 rising wedge surface 27 is formed. The clamping curvature 210 is in the inner jacket 28 of the winding drum 207 assigned a recess 29. The recess 29 is in the area of the insertion slot 30, which is formed with a clamping plate 31 is. Furthermore, the inner jacket 28 is distributed over the circumference arranged support surfaces 32a to 32d.

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 to be wound up in this version thin rolled strip is subsequently based on the in the figures 4a to 4c illustrated in detail:

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 Figure 4a is the Winding drum 207 in a rest position and is with its insertion slot 30 to the start of the strip 33 of the rolled strip 34 aligned. The beginning of the tape 33 is by means of tape feed, for. B. by a driver, not shown here, in arrow direction 35 in inserted the insertion slot 30 to the end of the clamping plate 31 been. The schematic of one as a dashed black box marked drive 16 drivable clamping sleeve 208 is located in their basic position. The clamping arch 210 lies over its stop surface 26 on the end face 36 of the recess facing her 29 on.

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 driven in via the drive 16 Winding direction 24 set in rotation. By against the Winding direction 24 increasing wedge area 27 decreases Radial gap 37 between the clamping sleeve 208 and the clamping plate 31 the insertion slot 30; the beginning of the tape 33 is between the Clamping curvature 210 and the clamping plate 31 clamped. After done Clamping creates a positive connection between the wedge surface 27 of the Clamping curvature 210, the beginning of the band 33 and the clamping plate 31; this causes the winding drum 207 to rotate and the actual winding up 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 207th and the clamping sleeve 208 in the winding direction 24 wind the tape turns 38 on the outer jacket 39 of the winding drum 207. there a certain force is exerted by the increasing band windings 38 the winding drum 207 applied; this can spread over support surfaces Apply 32a to 32d to the clamping sleeve 208. The recesses 40a to 40c on the inner jacket 28 of the winding drum 207 promote a 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 vice versa, and the winding drum 207 and the clamping sleeve 208 consequently rotate in the opposite direction according to arrow 41 in FIG. 5. According to Figure 5, the rolled strip 35 is completely from the outer jacket 39 of the winding drum 207 unwound. The beginning of the tape 33 released by the wedge surface 27 of the clamping arch 206, and there the winding drum 207 from that on the end face 36 of the recess 29 applied stop surface 26 of the clamping arch 210 the winding drum 207 can be moved into the position shown in FIG. rotate the defined threading position, in which it leads to a new one Winding process is ready. At the same time, the beginning of the band 33 represents the end of the tape during unwinding, automatically released and can by a strip tension acting on the rolled strip 24 (cf. arrow 42) in interaction with the rotation of the clamping sleeve 208 and the winding drum 207 are unwound in the direction of arrow 41.
