Abstract

Device for longitudinal division of a band (2) into several strips (4a, 4b) and for winding the strips (4a, 4b) onto a reel (6). To ensure alignment of the edges of the individual strips (4a, 4b) on the reel, the traction exerted on each strip (4a, 4b) on the reel (6) common to all strips is controlled at a constant value. In addition, an individually adjustable control roll (5a, 5b) for each strip (4a, 4b) acts as a guiding element for the strips.

Description

Vorrichtung zum Längsteilen eines Bandes und Aufwickeln der Streifen des geteilten BandesDevice for longitudinally dividing a band and winding up the strips of the divided band
Die Erfindung bezieht sich auf eine Vorrichtung zum Längsteilen eines Bandes in mehrere Streifen und Aufwickeln der Streifen auf einer Aufwickelhaspel oder zwei Aufwickelhaspeln mit im wesentlichen gleicher Wickelachse mit zwischen einer Schere zum Längsteilen und der Aufwickel haspel bzw. den Aufwickelhaspeln vorgesehenen Lenkvorrichtung für den Bandlauf der Streifen.The invention relates to a device for longitudinally dividing a tape into several strips and winding the strips on a take-up reel or two take-up reels with essentially the same winding axis with a scissor for slitting and the take-up reel or the take-up reel steering device for the strip running of the strips .
Beim Aufwickeln der Streifen eines längsgeteilten Bandes au einer Haspel wird ein minimaler Versatz der Kanten der Streifen auf der Haspel gefordert. Diese Forderung ist ohne den Bandlauf der Streifen beeinflussende Hilfsmittel nicht zu erfüllen. Aufgrund von Unterschieden in der Banddicke in Bandquerrichtung würden die Streifen beim Aufwickeln ineinander- oder auseinanderlaufen, wenn dem nicht mit besonderen Lenkmitteln, zum Beispiel verstellbaren und/oder bikonischen, baliigen oder bogig eingestellten Steuerrollen, entgegengewirkt würde. In der Praxis hat sich aber gezeigt, daß allein mit solchen Mitteln zum Lenken des Bandlaufes di Forderung nach einem minimalen Kantenversatz der Streifen auf der Aufwickelhaspel noch nicht erfüllt werden kann. Deshalb ist in einer älteren Patentanmeldung (P 38 28 995•→—1 ) bereits vorgeschlagen worden, daß die Lenkvorrichtung derart gegen die Aufwickelhaspel verstellba ist, daß die freie Länge der Streifen zwischen ihrer Austrittsstelle aus der Lenkvorrichtung und ihrem Auflaufpunkt auf dem Bund an der Aufwickelhaspel während de gesamten Wickelvorganges gleichbleibend ist.When winding up the strips of a slit strip on a reel, a minimal offset of the edges of the strips on the reel is required. This requirement is not without aids influencing the strip run of the strips to fulfill. Due to differences in the strip thickness in the transverse direction of the strip, the strips would run into one another or diverge when they were wound up, if this were not counteracted with special steering means, for example adjustable and / or biconical, balanced or curved control rollers. In practice, however, it has been shown that only such means for guiding the tape run can not meet the requirement for a minimal edge offset of the strips on the take-up reel. Therefore, it has already been proposed in an older patent application (P 38 28 995 • → —1) that the steering device can be adjusted against the take-up reel in such a way that the free length of the strips between their point of exit from the steering device and their point of impact on the collar on the Take-up reel is constant during the entire winding process.
Bei einer anderen bekannten, aber gattungsfremden Vorrichtung (DE 36 07 136 CD ist vorgesehen, in einem von oben nach unten verlaufenden, der Längsteilschere nachgeordneten Führungsabschnitt die benachbarten Streifen auseinander und zu zwei Aufwickelhaspeln zu führen, die parallel zueinander aber mit Abstand voneinander angeordnet sind. Bei einer solchen Vorrichtung besteht zwar nicht die Gefahr des Ineinanderlaufens der einzelnen Streifen, doch läßt sich eine kantengerade Aufwicklung der einzelnen Streifen nicht erreichen, die allerdings in diesem Fall auc nicht kritisch ist. Ein weiterer Nachteil besteht in dem großen apparativen Aufwand für die beiden Aufwickelhaspel und in dem von ihnen beanspruchten Platzbedarf.In another known, but non-generic device (DE 36 07 136 CD it is provided to separate the adjacent strips in a guide section running from top to bottom, arranged downstream of the slitting shears, and to lead to two winding reels, which are arranged parallel to one another but at a distance from one another. Although there is no risk of the individual strips running into one another in such a device, it is not possible to wind up the individual strips in a straight line, which, however, is also not critical in this case. A further disadvantage is the large outlay on equipment for the two take-up reels and in the space they require.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, die mit möglichst geringem Aufwand ein kantengerades Aufwickeln der Streifen ermöglicht. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Lenkvorrichtung für jeden Streifen ein individuell einstellbares Lenkmittel aufweist und die Aufwickelhaspel auf einen konstanten Bandzug für jeden Streifen einstellbar ist bzw. sind.The invention has for its object to provide a device of the type mentioned, which enables a straight edge winding of the strips with the least possible effort. This object is achieved in that the steering device has an individually adjustable steering means for each strip and the take-up reel is or are adjustable to a constant tape tension for each strip.
Bei der erfindungsgemäßen Vorrichtung wird der Tendenz der Streifen zu einem Querverlaufen in Richtung des Ortes der. höchsten Bandspannung durch das individuell auf den Streife einstellbare Lenkmittel dauerhaft entgegengewirkt, weil in Verbindung mit der auf konstanten Bandzug einstellbaren Aufwickelhaspel trotz Aufwickeins der Streifen auf einer einzigen Aufwickelhaspel oder zwei Aufwickelhaspeln mit gleicher Achse die Zugverhältnisse während des Aufwickeins auch bei unterschiedlichen Wickeldurchmessern von Streifen zu Streifen sich nicht verändern.In the device according to the invention, the tendency of the strips to run transversely in the direction of the location of the. highest belt tension is counteracted permanently by the steering means, which can be individually adjusted to the strip, because in connection with the winding reel, which can be adjusted to a constant strip tension, despite winding the strips on a single winding reel or two winding reels with the same axis, the tensile conditions during winding, even with different winding diameters from strip to strip don't change.
Nach einer Ausgestaltung der Erfindung weist jedes Lenkmittel mindestens eine verstellbare Steuerrolle auf, die von dem zugehörigen Streifen teilweise umschlungen ist. Um die Lenkaufgabe erfüllen zu können, können die Steuerrollen um mehrere Achsen, aber auch in der Höhe verstellbar sein. Sofern aufgrund der Bandführung der natürliche Umschlingungswinkel der Steuerrolle die Lenkwirkung nur schwer erreichbar wird, kann der Umschlingungswinkel durch eine weitere Rolle vergrößert werden, so daß die Lenkmittel von einem Steuerrollenpaar gebildet werden.According to one embodiment of the invention, each steering means has at least one adjustable control roller which is partially wrapped in the associated strip. In order to be able to perform the steering task, the control rollers can be adjustable about several axes, but also in height. If the steering effect is difficult to achieve due to the band guidance of the natural wrap angle of the control roller, the wrap angle can be increased by a further roller, so that the steering means are formed by a pair of control rollers.
Vorzugsweise sind die Steuerrollen für die einzelnen Streifen quer zur Bandlaufrichtung gegeneinander versetzt. Auf diese Art und Weise hat jede Steuerrolle genügend Bewegungsfreiheit für den Lenkvorgang.The control rollers for the individual strips are preferably offset from one another transversely to the direction of travel of the strip. In this way, each control roller has enough freedom of movement for the steering process.
Für den exakten Bandlauf auf der bzw. den Aufwickelhaspeln hat sich bewährt, wenn der Haspel eine für alle Streifen gemeinsame Umlenkrolle vorgeordnet ist, deren Abstand gegenüber der Haspelachse einstellbar ist. Die Umlenkrolle sollte aus einzelnen Ringsegmenten bestehen.For the exact tape run on the winding reel (s), it has proven useful if the reel has one for all strips common deflection roller is arranged, the distance from the reel axis is adjustable. The pulley should consist of individual ring segments.
Um die geometrischen Verhältnisse beim Aufwickeln gleichzuhalten, was für ein kantengerades Aufwickeln wesentlich ist, ist nach einer weiteren Ausgestaltung vorgesehen, daß die Lenkmittel und die Umlenkrolle auf einem verfahrbaren Gerüst angeordnet sind. Vorzugsweise sind die Lenkmittel auf einem gemeinsamen Gerüst angeordnet.In order to keep the geometrical conditions when winding up, which is essential for straight winding, according to a further embodiment it is provided that the steering means and the deflection roller are arranged on a movable scaffold. The steering means are preferably arranged on a common framework.
Die Einstellung des konstanten Bandzuges an der bzw. den Aufwickelhaspeln läßt sich nach einer weiteren Ausgestaltung der Erfindung dadurch verwirklichen, daß die Aufwickelhaspel mit mindestens einem Bremsring für jeden Streifen bestückt ist, dessen Schlupf entsprechend der Längendifferenz zwischen den Streifen einstellbar ist. Die Bestückung mit einem Bremsring für jeden Streifen läßt sich sowohl bei einer einzigen Aufwickelhaspel als auch bei zwei Aufwickelhaspeln mit jeweils individuellem Antrieb verwirklichen. Bei zwei Aufwickelhaspeln mit individuellem Antrieb wird die Längendifferenz zwischen dem Bandstreifen aber auch ohne Bestückung mit Bremsringen ausgeglichen, wenn die Antriebe auf konstanten Bandzug eingestellt sind. Bei einer Bestückung mit Bremsringen sitzen vorzugsweise im Haspelkern, auf dem die Bremsringe gelagert sind, druckmittelbeaufschlagte Bremsstücke. Über die Einstellung des Druckmittels kann die Bremskraft eingestellt werden. Di Bremsringe selbst sollten als Spannhülsen für 'die Wickelhülsen ausgebildet sein. Auf diese Art und Weise läßt sich erreichen, daß die Spannhülsen rutschfest auf den Bremsringen sitzen.The setting of the constant tape tension on the winding reel or reels can be realized according to a further embodiment of the invention in that the reel is equipped with at least one brake ring for each strip, the slip of which is adjustable according to the length difference between the strips. The equipment with a brake ring for each strip can be realized both with a single take-up reel and with two take-up reels, each with an individual drive. With two take-up reels with individual drives, the difference in length between the strip strips is compensated for even without brake rings if the drives are set to constant strip tension. When equipped with brake rings, pressure elements pressurized brake pieces are preferably seated in the reel core on which the brake rings are mounted. The braking force can be adjusted by adjusting the pressure medium. Di brake rings themselves should be designed as clamping sleeves for 'the winding tubes. In this way it can be achieved that the clamping sleeves sit non-slip on the brake rings.
Zur Steuerung der Lenkmittel ist nach einer Ausgestaltung der Erfindung vorgesehen, daß den Lenkmitteln Istwertaufnehmer für den Zug und die Lage der Streifen zugeordnet sind.To control the steering means is provided according to an embodiment of the invention that the steering means actual value sensor for the train and the position of the strips assigned.
Im folgenden wird die Erfindung anhand einer ein Ausführungsbeispiel darstellenden Zeichnung näher erläuter Im einzelnen zeigen:The invention will be explained in more detail below with reference to a drawing illustrating an exemplary embodiment:

Die in Fig. 1 bis 3 dargestellte Vorrichtung besteht aus einer mit Kreismessern bestückten Längsteilschere 1, der zu teilendes Band 2 zugeführt wird, unmittelbar der Längsteilschere 1 angeordnete Rollen 3> die das beispielsweise in zwei Streifen 4a, b längsgeteilte Band in einer Ebene halten, einer aus zwei Steuerrollen 5a,5b bestehenden Lenkvorrichtung, einer für die beiden Streifen 4a,4b gemeinsamen Aufwickelhaspel 6 mit einer entsprechend der Anzahl der Streifen 4a,4b axial in Segmente unterteilte ihr unmittelbar vorgeordneten Umlenkrolle 7. Die Umlenkroll 7 ist in einer Führung 8 höhenverstellbar. Die Steuerrolle 5a ist verschwenkbar und die Steuerrolle 5b sowohl verschwenkbar als "auch auf einer Führung 9 verfahrbar. Die Steuerrollen 5a, b mit ihrer Führung 9 sowie die Umlenkrolle 7 mit ihrer Führung 8 sind auf einem gemeinsamen Gerüst 10 aufgebaut, das in einer Führung 11 gegenüber der Aufwickelhaspel 6 verfahrbar ist. Das Gerüst 10 trägt außerdem für jeden Streifen 4a,4b einen Istwertaufnehmer 12a in Form von Druckmeßdosen für den Zug der Streifen 4a,4b und einen Meßwertaufnehmer 12b in Form einer Lichtschranke oder Diodenzeilenkamera für die Lage der Kanten der Streifen 4a,4b.The device shown in FIGS. 1 to 3 consists of a slitting shear 1 equipped with circular knives, to which the strip 2 to be divided is fed, the slitting shears 1 arranged directly > rollers 3 > which hold the slice, which is divided, for example, into two strips 4a, b in one plane, a steering device consisting of two control rollers 5a, 5b, a take-up reel 6 common to the two strips 4a, 4b and having a deflection roller 7 which is axially divided into segments according to the number of strips 4a, 4b. The deflection roller 7 is adjustable in height in a guide 8 . The control roller 5a is pivotable and the control roller 5b both can also be moved on a guide 9. The control rollers 5a, b with their guide 9 and the deflection roller 7 with their guide 8 are constructed on a common stand 10 which can be moved in a guide 11 relative to the take-up reel 6. The stand 10 also carries for each strip 4a, 4b an actual value sensor 12a in the form of pressure transducers for the pulling of the strips 4a, 4b and a measuring value sensor 12b in the form of a light barrier or diode line camera for the position of the edges of the strips 4a, 4b.
Nachdem gemäß Fig. 1 die Streifen 4a,4b an der Aufwickel¬ haspel 6 angeschlossen sind, wird gemäß Fig. 2 die Umlenkrolle 7 aus ihrer oberen Position in ihre untere Positition verfahren, in der ihre Achse annähernd in der gleichen horizontalen Ebene wie die Achse der Aufwickel¬ haspel 6 liegt. In dieser Position steht sie in geringem Abstand zum Anwickelpunkt der Streifen an der Aufwickelhaspel 6. In Abhängigkeit vom Aufwickelfortschritt wird durch Verfahren des Gerüstes 10 die Umlenkrolle 7 von der Achse der Aufwickelhaspel 6 fortbewegt, wobei jedoch ih Abstand vom aufgewickelten Bund im wesentlichen beibehalten wird, wie Fig. 3 zeigt. Die Meßwertaufnehmer 12a, 12b für die Erfassung des Zuges der Streifen und der Lage der Kanten der Streifen liefern an eine Regel- und Steuereinrichtung Signale, die in Abhängigkeit von diesen Signalen die Steuerrollen 5a,5b im Sinne eines gewünschten Bandlaufs einstellen.After the strips 4a, 4b are connected to the winding reel 6 according to FIG. 1, the deflection roller 7 is moved from its upper position to its lower position according to FIG. 2, in which its axis is approximately in the same horizontal plane as the axis the reel 6 is located. In this position, it is at a short distance from the winding point of the strips on the take-up reel 6. Depending on the take-up progress, the guide roller 7 is moved away from the axis of the take-up reel 6 by moving the stand 10, but its distance from the wound up coil is essentially maintained, 3 shows. The transducers 12a, 12b for the detection of the tension of the strips and the position of the edges of the strips supply signals to a regulating and control device which, depending on these signals, set the control rollers 5a, 5b in the sense of a desired tape run.
'Gemäß Fig. 4 und 5 sind auf einem Haspelkern 13, der von einem nicht dargestellten Antrieb angetrieben ist, für jeden Streifen 5a,5b ein Bremsring I4a,l4b drehbar gelagert. Im Kern 13 sind über dessen Umfang verteilt Bremskörper 15a, 15b eingelagert. Diese Bremskörper 15a, 15b lassen sich mittels Druckerzeugern 1δa,l6b, denen über mit Zuleitungen 17a, 1'7b Druckmittel zuführbar ist, gegen die Innenseite der Bremsringe I4a,l4b drücken. Von der Größe dieser Druckbeaufschlagung hängt die Kraft ab, mit der die Bremsringe I4a,l4b gegenüber dem Kern 13 verdrehbar sind. Über die Einstellung der Druckbeaufschlagung läßt sich als der Bandzug für die Streifen 5a,5b einstellen. 'According to Fig. 4 and 5, 5b is a brake ring I4a, L4B are on a bobbin core 13, which is driven by a drive, not shown, for each strip 5a is rotatably supported. Brake bodies 15a, 15b are distributed in the core 13 distributed over its circumference. These brake bodies 15a, 15b can be generated by means of pressure generators 1δa, 16b, via which Supply lines 17a, 1 ' 7b pressure medium can be supplied, press against the inside of the brake rings I4a, 14b. The force with which the brake rings 14a, 14b can be rotated relative to the core 13 depends on the size of this pressurization. By adjusting the pressurization, the band tension for the strips 5a, 5b can be set.
In den Bremsringen I4a,l4b sind in entsprechender Weise druckmittelbeaufschlagte Druckkörper I8a,l8b eingelagert, die durch ein Druckmittel gegen Wickelhülsen 19a, 19b für d Streifen 5a,5b gedrückt werden können. Auf diese Art und Weise ist es möglich, die Hülsen 19a, 19b auf den Bremsring drehfest festzusetzen, so daß aufgrund des alleinigen möglichen Schlupfes zwischen dem Kern 13 und den Bremsring 14a, 15a die Verhältnisse wegen des geforderten einstellbar konstanten Bandzuges eindeutig sind.In the brake rings I4a, l4b, pressure bodies I8a, l8b, which are acted upon by pressure medium, are embedded in a corresponding manner and can be pressed by a pressure medium against winding sleeves 19a, 19b for d strips 5a, 5b. In this way, it is possible to fix the sleeves 19a, 19b on the brake ring in a rotationally fixed manner, so that due to the only possible slippage between the core 13 and the brake ring 14a, 15a, the conditions are clear because of the required adjustable, constant band tension.
In Fig. 7 sind zwei Aufwickelhaspel 6a,6b dargestellt, deren Wickelachsen 26a,26b im wesentlichen miteinander fluchten und deren Antriebe 27a,27b auf konstanten Bandzug einstellbar sind. Die beiden Aufwickelhaspel lassen sich verfahren, um z.B. die aufgewickelten Streifen abnehmen zu können. Die Wickelachsen bzw. Wickeltrommeln lassen sic austauschen. 7 shows two take-up reels 6a, 6b, the winding axes 26a, 26b of which are essentially in alignment with one another and the drives 27a, 27b of which can be adjusted to constant strip tension. The two take-up reels can be moved to e.g. to be able to remove the wound strips. The winding axes or winding drums can be replaced.
