Description
Die Erfindung betrifft eine Vorrichtung zum Kennzeichnen der Drahtenden von Drahtwindungen, welche aus einem Drahtwickler einem Aufnahmehaspel zugeführt und für bestimmte Gebindegrößen vor der Aufnahmehaspel durchtrennt werden.The invention relates to a device for identifying the wire ends of wire windings, which are fed from a wire winder to a take-up reel and cut through for certain pack sizes in front of the take-up reel.
Hinter Maschinen zum Ziehen oder Behandeln von Draht, z.B. hinter einer Drahtschleifvorrichtung, werden sogenannte Drahtwickler eingesetzt, welche den fertig behandelten Draht zu aneinanderhängenden Windungen mit gleichmäßigem Krümmungsradius formen. Die einzelnen Windungen werden von einem Aufnahmehaspel zu Drahtgebinden aufgenommen. Sobald eine gewünschte Gebindegröße erreicht ist, muß der aus dem Drahtwickler kommende Draht vor der Aufnahmehaspel durchtrennt werden. Um die Stillstandszeiten der Gesamtanlage möglichst gering zu halten, strebt man zwar hohe Gewichte der von der Aufnahmehaspel aufgenommenen Drahtgebinde an, in der Praxis werden aber öfters auch kleine Gebinde verlangt. Um die Stillstandszeiten trotzdem möglichst niedrig zu halten, versucht man maximale Drahtgebinde in die Aufnahmevorrichtung (z.B. Aufnahmehaspel) einer Wickelstation zu bringen und danach das Wickelgut in einem separaten Arbeitsgang dem gewünschten Gewicht entsprechend zu separieren. Dieser zusätzliche Arbeitsgang ist aufwendig. Bei Erreichen des jeweils gewünschten Gebindes versucht man, die entsprechende Stelle einer Drahtwindung zu markieren, um sie an dieser Stelle nachher durchzuschneiden. Aussortieren und Abschneiden ist eine hohe zusätzliche Arbeit.Behind wire drawing or treating machines, e.g. behind a wire grinding device, so-called wire winders are used, which form the finished wire into contiguous turns with a uniform radius of curvature. The individual turns are taken up by a take-up reel to wire packages. As soon as a desired container size is reached, the wire coming out of the wire winder must be cut in front of the take-up reel. In order to keep the downtimes of the entire system as short as possible, high weights of the wire bundles taken up by the take-up reel are aimed for, but in practice small bundles are often required. In order to keep the downtimes as short as possible, one tries to bring maximum wire bundles into the take-up device (e.g. take-up reel) of a winding station and then separate the material to be wound in a separate operation according to the desired weight. This additional step is complex. When the desired container is reached, an attempt is made to mark the corresponding point on a wire winding so that it can be cut through at this point. Sorting out and cutting off is a lot of additional work.
Die US-A-4261 191 beschreibt ein Verfahren zum Kennzeichnen der Drahtenden von Drahtwindungen, welche aus einem Drahtwickler mit Transpottrollen und einer Biegerolle zu einer Aufnahmehaspel geführt und für bestimmte Gebindegrößen vor der Aufnahmehaspel durchtrennt werden. Das beim Durchtrennen gebildete Drahtende wird in eine vom Wickelradius des Drahtgebindes abweichende Form gebracht. Dies erfolgt, indem die Biegerolle kurz vor dem Auslaufen des Drahtes auf das noch gespannte Drahtende zubewegt wird. Mittels einer anschließenden Schneidvorrichtung wird das Drahtende auf die richtige Länge abgeschnitten. Auf diese Weise ist das Drahtende zwar besonders gekennzeichnet, aber ein ununterbrochener Betrieb ist nicht möglich. Es ist sehr unwirtschaftlich, bei kleinen Gebindegrößen die Maschine jeweils neu anlaufen zu lassen, bei Erreichen des gewünschten Gebindegewichtes die Maschine stillzusetzen und dann das kleine Gebinde zu reparieren.US-A-4261 191 describes a method for marking the wire ends of wire windings which are led from a wire winder with transport rollers and a bending roller to a take-up reel and are cut for certain pack sizes in front of the take-up reel. The wire end formed during cutting is brought into a shape that deviates from the winding radius of the wire container. This is done by moving the bending roller towards the still tensioned wire end shortly before the wire runs out. The end of the wire is cut to the correct length by means of a subsequent cutting device. In this way, the wire end is specially marked, but uninterrupted operation is not possible. It is very uneconomical to restart the machine for small container sizes, stop the machine when the desired container weight is reached and then repair the small container.
Der Erfindung liegt die Aufgabe zugrunde, die Stillstandszeiten eines Drahtwicklers auf ein Minimum zu reduzieren bzw. vollständig zu eleminieren, auch dann, wenn kleine Gebindegrößen gefertigt werden, sowie die einzelnen Drahtgebinde ohne Schwierigkeit separieren zu können.The object of the invention is to reduce the downtimes of a wire winder to a minimum or to eliminate them completely, even when small container sizes are being manufactured, and to be able to separate the individual wire containers without difficulty.

Fig. 6 zeigt ein Ausführungsbeispiel, bei welchem beide beim Trennen entstehenden Drahtenden abgebogen werden. Das Anfangsstück des Drahtes wird zunächst in der Biegestellung I (Fig. 6b) durch die Kurvenaussparung 22 der linken Schneidrolle 21 und das Biegestück 23 der rechten Schneidrolle 24 nach außen abgebogen. Nach der Drehung der Schneidrollen um weitere 90o (Fig. 6c) erfolgt durch die Kurvenaussparung 25 und das Biegestück 26 eine Biegung nach innen, sodaß das Drahtende wieder in Richtung parallel zur Ausgangsstellung zeigt. In der Stellung Fig. 6d wird der Draht durchtrennt, nach einer weiteren 90o Drehung der Schneidrollen wird der Drahtanfang für das nächste Gebinde durch das Biegestück 27 in der Kurvenaussparung 28 abgebogen. Die beiden Drahtenden sind auf unterschiedliche Weise abgebogen, sodaß sie gut zu unterscheiden sind.Fig. 6 shows an embodiment in which both wire ends resulting from the cutting are bent.

Das Ausführungsbeispiel gemäß Fig. 7a - 7c zeigt ein etwas anderes Prizip einer Schneidvorrichtung. Die Schneid- und Biegeeinheit 29 ist ebenfalls im Verläuf des Wickelgutes so angeordnet und ausgerichtet, daß es zwischen einem stationären Grundelement 30 und einem um das Grundelement 30 auf einem Teilkreisbogen herumschwenkbaren Trabantenelement 31, hindurchläuft. Die Ausgangsstellung ist in Fig. 7a angedeutet, sie umfaßt auch eine Nebenskizze in Ansicht A. Sowohl das Grundelement 30 als auch das Trabantenelement 31 haben an ihrem Umfang eine Schneidkante. Das Trabantenelement 31 ist an einem Arm 32, deren Antriebsachse 33 koaxial mit dem Zentralpunkt des Grundelementes 30 verläuft. In der Ausgangsstellung Fig. 7a ist die Schneidkante des Grundelementes 30 von der Bahn des Drahtes 5 abgewandt und die Schneidkante des Trabantenelementes 31 weist auf den Zentralpunkt des Grundelementes. Beim Auslösen des Schneidvorganges wird das Trabantenelement 31 mit Hilfe des Armes 32 um den Zentralpunkt des Grundelementes 30 geführt, wie der Pfeil in Fig. 7b andeutet. Dabei wird der Draht 5 um das Grundelement 30 gebogen und in der Endstllung (Fig.7b) durch die beiden sich in Schnittstellung befindlichen Schnittkanten getrennt. Auf dem Schwenkweg des Trabantenelementes 31 wurde auch das abgeschnittene Drahtende 34 gebogen wie aus Fig. 7c deutlich zu erkennen ist. Sofort nach dem Trennvorgang geht das Trabantenelement 31 wieder in seine Ausgangsstellung zurück wie Fig. 7c andeutet. Zweckmäßig wird die gesamte Schneideinrichtung während des Trennvorganges in Richtung der Drahtbewegung (Pfeil 35) mitgeführt und nach Beendigung wieder zurückgeführt.
In Fig. 8 ist eine Vorrichtung zum Biegen und Trennen des Drahtes 5 dargestellt, bei welcher der von der Biegerolle 9 kommende Draht von zwei Stützrollen 36 und 37 aufgenommen wird. Zwischen beiden Stützrollen ist ein feststehendes Schneidmesser 38 und ein auf dieses zu bewegbares Schneidmesser 39 angeordnet.
In der Stellung a (Ausgangsstellung) der Vorrichtung befinden sich die SChneidmesser auseinandergefahren links bzw. rechts vom Draht 5. Während des Vorganges "Schneiden und Biegen" fährt die Vorrichtung in die Stellung b mit dem sich vorwärtsbewegenden Draht mit. Dabei fährt das Schneidmesser 39 in die Schnittstellung, legt den Draht in die dargestellte Form, sodaß nach dem Trennvorgang die beiden entstehenden Drahtenden abgebogen sind.
Die Vorrichtung gemäß Fig. 9 ist ähnlich aufgebaut, nur mit dem Unterschied, daß eine einzige Stützrolle 40 vorgesehen ist. Dies führt dazu, daß nur das über die Stützrolle 40 beim Schneidvorgang gemäß Stellung b gehaltene Drahtteil abgebogen wird. Im übrigen ist die Funktionsweise die gleiche wie beim Ausführungsbeispiel nach Fig. 8.
Alle Vorrichtungen sind nur schematisch dargestellt. Je nach Bedarf können die Biege- und Schneidvorrichtungen auch mit einer Drahtaufnahmevorrichtung kombiniert werden. Die Wickelenden können auch ein zusätzliche Kennzeichnung erhalten. (Z. B. Farbe, Nummer, Prägung u.s.w.).The exemplary embodiment according to FIGS. 7a-7c shows a somewhat different principle of a cutting device. The cutting and bending
