Description

Die Erfindung betrifft eine Vorrichtung zum Gerade­richten von zu Spulen aufgewickeltem Bandmaterial und zur Einführung desselben in den Vorschub einer Weiterverar­beitungsmaschine, bestehend aus einem Abwickler und einem diesem nachgeordneten Richtwerk, welches mit Unter- und Oberrichtrollen sowie ggf. Einzugrollen ausgerüstet ist.The invention relates to a device for straightening coil material wound into spools and for introducing the same into the feed of a further processing machine, consisting of an unwinder and a straightening unit arranged downstream thereof, which is equipped with lower and upper straightening rollers and, if appropriate, feed rollers.

Es ist bekannt, den Abwickler sowie das Richtwerk einer gattungsgemäßen Vorrichtung voneinander getrennt mit einem bestimmten Abstand anzuordnen. Zwischen Abwick­ler und Richtwerk befindet sich eine Übergabeeinrichtung, welche heb- und senkbar ausgeführt ist und zusätzlich in Bandlaufrichtung ausschiebbar sowie einschiebbar ist. Der Bandanfang einer auf dem Abwickler befindlichen Spu­le wird geleitet von der Andruckrolle des Abwicklers und angetrieben von dessen Antrieb über eine Fläche der Übergabeeinrichtung geschoben und gelangt so in das Richt­werk. Hinter dem Richtwerk ist ein stationärer Hubtisch vor­gesehen, welcher das Überleiten des Bandanfanges aus dem Richtwerk in den Vorschub einer nachgeordneten Weiterverar­beitungsmaschine, beispielsweise einer Presse, bewirkt. Diese bekannte Vorrichtung weist den Nachteil auf, daß einerseits zwischen Abwickler und Richtwerk eine feststehende Übergabeeinrichtung und andererseits zwischen Richtwerk und nachgeordneter Weiterverarbeitungsmaschine ein stationärer Hubtisch vorgesehen sind, was einen vergleichsweise großen Aufwand darstellt, ganz abgesehen davon, daß hierdurch auch eine optimale Schlaufenbildung zwischen Richtwerk und Vorschub der Weiterverarbeitungsmaschine nicht zu verwirklichen ist.It is known to arrange the unwinder and the straightening unit of a generic device separately from one another at a certain distance. Between the unwinder and the straightening unit there is a transfer device which can be raised and lowered and can also be pushed out and pushed in in the direction of the strip. The beginning of the tape of a spool located on the unwinder is guided by the pressure roller of the unwinder and driven by its drive over a surface of the transfer device and thus reaches the straightening unit. A stationary lifting table is provided behind the straightening unit, which transfers the beginning of the strip from the Straightening mechanism in the feed of a downstream processing machine, for example a press. This known device has the disadvantage that, on the one hand, a fixed transfer device is provided between the unwinder and the straightening unit and, on the other hand, a stationary lifting table is provided between the straightening unit and the downstream processing machine, which represents a comparatively large outlay, quite apart from the fact that this also results in optimal loop formation between the straightening unit and Feed of the processing machine is not possible.

Von diesem Stand der Technik ausgehend liegt der Erfin­dung die Aufgabe zugrunde, unter Vermeidung vorerwähnter Nachteile eine gattungsgemäße Vorrichtung zu schaffen, welche nicht nur eine unmittelbare Bandanfangübernahme "Abwickler- Richtwerk", sondern auch eine Bandanfangüber­gabe "Richtwerk-Vorschub" und darüber hinaus eine derar­tige Einstellung des Abstandes zwischen Richtwerk und Vor­schub der Weiterverarbeitungsmaschine ermöglicht, daß eine optimale Schlaufenausbildung gewährleistet ist.Starting from this prior art, the invention has for its object to provide a generic device while avoiding the aforementioned disadvantages, which not only an immediate tape start transfer "unwinding straightening unit", but also a tape start transfer "straightening unit feed" and beyond such a setting the distance between the straightening unit and the feed of the further processing machine enables an optimal loop formation to be guaranteed.

Erfindungsgemäß wird dies dadurch erreicht, daß das Richtwerk zwischen Abwickler und dem Vorschub der Wei­terverarbeitungsmaschine, vorzugsweise einer Presse, verfahrbar ist. Durch die verfahrbare Ausbildung des Richtwerkes kommen die bisher übliche Übergabeeinrichtung sowie der Hubtisch in Fortfall, da durch die Möglich­keit des Hin- und Herfahrens des Richtwerkes die Band­anfangübernahme sowie -übergabe durch das Richtwerk selbst erfolgt und darüber hinaus das Richtwerk in die Zwischen­stellung gefahren werden kann, die eine optimale Schlau­fenbildung des Bandmaterials ergibt.According to the invention, this is achieved in that the straightener can be moved between the unwinder and the feed of the further processing machine, preferably a press. Due to the movable training of the Straightening unit, the previously common transfer device and the lifting table are no longer in use, since the possibility of moving the straightening unit back and forth means that the beginning and transfer of the strip is carried out by the straightening unit itself and, moreover, the straightening unit can be moved into the intermediate position, which ensures optimal loop formation Band material results.

Vorzugsweise sind der Abwickler und das Richtwerk auf einer gemeinsamen Plattform od.dgl. angeordnet. Diese Plattform wird unmittelbar vor den Vorschub der Weiter­verarbeitungsmaschine gesetzt, so daß die Bandanfang­übergabe in den Vorschub derselben ohne Zwischenordnung besonderer Hilfsaggregate möglich ist.Preferably, the unwinder and the straightener or the like are on a common platform. arranged. This platform is placed directly in front of the feed of the further processing machine, so that the tape start transfer into the feed of the same is possible without intermediate arrangement of special auxiliary units.

Gemäß einer Ausführung der Erfindung ist das Richtwerk an einer oder mehreren Führungen angebracht - vorzugsweise nach Art einer Schwebebahn - aufgehängt, so daß unterhalb des Richtwerkes über dessen ganzen Fahrbereich ein völlig freier Raum vorhanden ist, welcher die Einstellung einer optimalen Schlaufe ermöglicht.According to one embodiment of the invention, the straightener is attached to one or more guides - preferably in the manner of a suspension railway - so that there is a completely free space underneath the straightener over its entire travel range, which enables the setting of an optimal loop.

Vorteilhaft ist die Führung bzw. sind die Führungen an ihrem bzw. ihren abwicklerseitigen Ende bzw. Enden heb- und senkbar und an ihrem bzw. ihren weiterverarbeitungs­ maschinenseitigen Ende bzw. Enden schwenkbar angebracht. Durch diese Einstellbarkeit ergibt sich eine optimale Übergabelage für den Bandanfang der auf dem Abwickler befindlichen Spule.The guide or the guides can advantageously be raised and lowered at their end or ends on the unwinder side and at their further processing machine-side end or ends pivotally attached. This adjustability results in an optimal transfer position for the beginning of the tape of the spool on the unwinder.

Das Richtwerk ist mit seinem oberen Teil an der Führung bzw. den Führungen aufgehängt, während sich in seinem unteren Teil die Richtwalzen sowie ggf. die Einzieh­rollen befinden oder umgekehrt. Der obere Teil trägt ebenfalls den Antrieb für das Verfahren des Richtwerkes.The upper part of the straightener is suspended from the guide or guides, while the lower part contains the straightening rollers and, if applicable, the retracting rollers, or vice versa. The upper part also carries the drive for moving the straightening unit.

Der die Richtrollen sowie ggf. die Einzugrollen enthaltende Teil des Richtwerkes ist an dessen der Führung bzw. den Führungen zugeordnetem Teil angeflanscht, so daß die unterschiedlichsten Richtköpfe Verwendung finden können.The part of the straightening unit containing the straightening rollers and possibly the feed rollers is flanged to the part assigned to the guide or the guides so that a wide variety of straightening heads can be used.

Nach einem weiteren Merkmal der Erfindung ist bzw. sind das abwicklerseitige Ende der Führung bzw. die abwickler­seitigen Enden der Führungen mittels mindestens eines Stellgliedes am Abwickler angelenkt. Das weiterverarbeitungs­maschinenseitige Ende der Führung bzw. die weiterverarbei­tungsmaschinenseitigen Enden der Führungen ist bzw. sind an einer oder mehreren Stützen schwenkbar angebracht, so daß bei Betätigung des Stellgliedes bzw. der Stellglieder die Führung bzw. Führungen eine Schwenkbewegung um die hori­ zontale Achse an der Stütze bzw. den Stützen ausführen.According to a further feature of the invention, the unwinding end of the guide or the unwinding end of the guides is or are articulated on the unwinder by means of at least one actuator. The processing machine end of the guide or the processing machine ends of the guides is or are pivotally attached to one or more supports, so that when the actuator or actuators are actuated, the guide or guides pivots around the hori Execute the central axis on the support or supports.

Die Führung kann von einem I-Profil-Träger gebildet sein, welcher mit einer Zahnstange ausgerüstet ist, die mit einem Antriebsritzel des Richtwerkes kämmt. Es ist jedoch auch möglich, das Richtwerk mittels eines Spindelantrie­bes/Hydrozylindern usw. zu verfahren.The guide can be formed by an I-profile carrier which is equipped with a toothed rack which meshes with a drive pinion of the straightening unit. However, it is also possible to move the straightener by means of a spindle drive / hydraulic cylinders etc.

An dem Richtwerk ist abwicklerseitig ein frei vorragendes Greiferbackenpaar vorgesehen, wobei die Anstellwinkel der oberen und/oder unteren Greiferbacke getrennt einstellbar sind. Das Greiferbackenpaar dient dem Erfassen des Bandan­fanges der auf dem Abwickler befindlichen Spule sowie der Übernahme an das Richtwerk im Zusammenwirken mit dem Antrieb des Abwicklers. Außerdem wird durch das Betätigen des Grei­ferbackenpaares ein Begradigen des Bandanfanges vor der Über­nahme in das Richtwerk bewirkt. Das Richtwerk weist einen Getrieberegelmotor auf, dessen Geschwindigkeit stufenlos einstellbar ist.A freely projecting pair of gripper jaws is provided on the unwinding unit, the angle of attack of the upper and / or lower gripper jaw being separately adjustable. The pair of gripper jaws is used to grasp the start of the tape of the spool on the unwinder and the transfer to the straightening unit in cooperation with the drive of the unwinder. In addition, pressing the pair of gripper jaws causes the beginning of the strip to be straightened before it is transferred to the straightening unit. The straightener has a geared control motor, the speed of which is infinitely adjustable.

Ein Ausführungsbeispiel der Erfindung ist an Hand der Zeichnung näher erläutert, und zwar zeigt diese eine Sei­tenansicht einer Baueinheit von Abwickler und Richtwerk.An embodiment of the invention is explained in more detail with reference to the drawing, and this shows a side view of a unit of unwinder and straightener.

Mit 1 ist der an sich bekannte Abwickler bezeichnet, der in herkömmlicher Weise ausgeführt und auf einer Plattform 2 angeordnet ist. Auf der Aufspanneinrichtung 3 des Abwicklers 1 befindet sich eine Spule 4 aus aufgewickeltem Bandmaterial. Der Bandanfang wird durch die Andruckrolle 5 auf der darunter befindlichen Windung gehalten.1 with the known unwinder is referred to in conventionally performed and arranged on a platform 2. On the clamping device 3 of the unwinder 1 there is a spool 4 of wound strip material. The beginning of the tape is held by the pressure roller 5 on the winding underneath.

Das Richtwerk 6 ist zwischen dem Abwickler 1 und dem nicht weiter dargestellten, herkömmlich ausgebildeten Vorschub einer Weiterverarbeitungsmaschine, beispielsweise einer Presse, verfahrbar ausgeführt. Im dargestellten Ausführungs­beispiel ist das Richtwerk 6 an einer Führung 7 aufgehängt, welche von einem I-Profil-Träger gebildet ist. Das Richt­werk 6 ist mit seinem oberen Teil 8 an der Führung 7 auf­gehängt. In seinem unteren Teil 9 befinden sich die Richt­rollen sowie die Einzugrollen. Das eigentliche Richtwerk mit Richtrollen und Einzugrollen ist ebenfalls herkömm­lich ausgeführt.The straightener 6 is designed to be movable between the unwinder 1 and the conventional feed of a further processing machine, for example a press, which is not shown. In the illustrated embodiment, the straightening unit 6 is suspended from a guide 7, which is formed by an I-profile carrier. The upper part 8 of the straightener 6 is suspended from the guide 7. In its lower part 9 there are the straightening rollers and the feed rollers. The actual straightening unit with straightening rollers and feed rollers is also conventional.

Die Führung 7 ist an ihrem abwicklerseitigen Ende 10 mit­tels eines Stellgliedes 11, beispielsweise in Form einer Zylinder-Kolben-Einheit oder eines Spindeltriebes, heb- und senkbar ausgebildet und am Abwickler 1 angelenkt. Das weiterverarbeitungsmaschinenseitige Ende 12 ist an einer Stütze 13 in einem Lagerbock 14 derselben um eine horizontale Achse schwenkbar angebracht. Die Stütze 13 befindet sich ebenfalls auf der Plattform 2.The guide 7 is designed to be raised and lowered at its unwind end 10 by means of an actuator 11, for example in the form of a cylinder-piston unit or a spindle drive, and articulated on the uncoiler 1. The processing machine end 12 is attached to a support 13 in a bearing block 14 of the same about a horizontal axis. The support 13 is also on platform 2.

Die Führung 7 ist mit einer Zahnstange ausgerüstet, die mit einem Antriebsritzel des Richtwerkes 6 kämmt, was der besseren Übersichtlichkeit halber nicht dargestellt ist.The guide 7 is equipped with a rack which meshes with a drive pinion of the straightening unit 6, which is not shown for the sake of clarity.

An dem Richtwerk 6 ist abwicklerseitig ein frei vorragen­des Greiferbackenpaar 15 vorgesehen, welches maulartig ausgeführt ist. Das Öffnen und Schließen der Greifer­backen erfolgt über Stellglieder 16, z.B. in Form von Zylinder-Kolben-Einheiten, Schneckenantrieben od.dgl. Der Anstellwinkel der oberen und unteren Greiferbacke ist getrennt einstellbar.A freely protruding pair of gripper jaws 15, which is designed like a mouth, is provided on the straightening unit 6 on the unwinder side. The gripper jaws are opened and closed via actuators 16, e.g. in the form of cylinder-piston units, worm drives or the like. The angle of attack of the upper and lower gripper jaws can be set separately.

Die Arbeitsweise der erfindungsgemäßen Vorrichtung ist wie folgt:The operation of the device according to the invention is as follows:

In der in der Figur dargestellten Position des Richt­werkes 6, d.h. also sowohl in bezug auf den Abwickler 1 als auch hinsichtlich seiner Höhenlage, ergibt sich eine optimale Übernahmelage für den Bandanfang durch das Richt­werk 6, welcher durch die Andruckrolle 9 am Arm 17 niedergehalten wird. Durch Betätigen des Antriebs des Abwicklers 1 wird der Bandanfang zwischen die geöffneten Backen des Greiferbackenpaares 15 geschoben. Durch Öffnen und Schließen derselben erfolgt eine Begradigung des Bandanfanges. In geöffneter Stellung des Greiferbackenpaares 15 erfolgt dann über den Antrieb des Abwicklers 1 der Vorschub zwischen die ggf. vorhandenen Einzugrollen oder aber zwischen die Richtrollen. In geöffneter Stellung des Greiferbackenpaares 15 wird dann das Richtwerk 6 zum weiterverarbeitungsma­schinenseitigen Ende 12 der Führung 7 unter gleichzeitigem Vorschub über den Abwicklerantrieb verfahren. Sobald das Ende 12 und damit der dahinter befindliche Vorschub, beispielsweise einer Presse, erreicht ist, erfolgt die Bandanfangübergabe an den Vorschub der nachgeschalteten Weiterverarbeitungsmaschine. Sobald der Bandanfang in diese eingeführt ist, fährt das Richtwerk 6 zurück, und zwar in eine Zwischenstellung, die entsprechend der Blechdicke des zu richtenden Bandmaterials eine optimale Schlaufenbildung ergibt. Da die erfindungsgemäße Vorrichtung unterhalb der Führung 7 sowie dem Richtwerk 6 völlig frei ist, kann die Schlaufensteuereinheit immer in den Scheitelpunkt der Schlaufe gefahren werden.In the position of the straightening unit 6 shown in the figure, ie both with respect to the unwinder 1 and with regard to its height, there is an optimal takeover position for the beginning of the tape by the straightening unit 6, which is held down by the pressure roller 9 on the arm 17. By pressing the drive of the unwinder 1, the beginning of the tape is between the open Baking the pair of gripper jaws 15 pushed. Opening and closing them straightens the beginning of the tape. In the open position of the pair of gripper jaws 15, the feed between the feed rollers that may be present or between the straightening rollers is then carried out via the drive of the unwinder 1. In the open position of the pair of gripper jaws 15, the straightening unit 6 is then moved to the end 12 of the guide 7 on the processing machine side, with simultaneous feed via the unwinder drive. As soon as the end 12 and thus the feed located behind it, for example a press, has been reached, the beginning of the tape is transferred to the feed of the downstream processing machine. As soon as the beginning of the strip has been inserted into it, the straightening mechanism 6 moves back into an intermediate position which, in accordance with the sheet thickness of the strip material to be straightened, results in optimal loop formation. Since the device according to the invention is completely free below the guide 7 and the straightening unit 6, the loop control unit can always be moved into the apex of the loop.

Die Verschiebung des Richtwerkes 6 erfolgt mittels eines Getrieberegelmotors. Zur Regelmotorsteuerung findet ein Frequenzumrichter (sinus moduliert) Verwendung. Der Hoch­lauf, der Tieflauf sowie die Vorfahrgeschwindigkeit sind stufenlos regelbar, wobei der Motor mit einer Federdruck­ scheibenbremse versehen ist.The straightening mechanism 6 is shifted by means of a geared control motor. A frequency converter (sine modulated) is used to control the control motor. The run-up, the run-down and the forward speed are infinitely variable, the motor with a spring pressure disc brake is provided.

Die Bedienung erfolgt mittels einer Steuerflasche, die der Bediener während der Bandübergabe ständig in der Hand hält.It is operated by means of a control bottle, which the operator always holds in his hand during the tape transfer.

Die Steuerflasche, die in Bedienhöhe an einer Stromzuführungs­schiene hängt, enthält alle Bedienelemente für das Richt­werk 6 sowie die Bandanfangtransportanlage.The control bottle, which hangs on a power supply rail at operating height, contains all the operating elements for the straightening unit 6 and the conveyor start conveyor.

Eine weitere Steuerflasche, die sich in der Nähe des Ab­wicklers befindet, enthält die Bedienelemente für den Ab­wickler sowie die hydraulisch betätigte Andruckrolle.Another control bottle, which is located near the unwinder, contains the controls for the unwinder and the hydraulically operated pressure roller.
