Abstract

The cutting part (6) of the cutting head moves through a set arc (b) off an electromotorized cam and works with a fixed second cutting part. Both cutting parts use several short blades (14) which are radiussed to suit arc (b). Drive is by housed motor whose projecting spindle is powered by cam through angle gearing. The longitudinal cutter axis (16) of the cutting head is at a slight angle to the axis (17) of the drive.

Description

Die Erfindung betrifft eine Vorrichtung zum Entfernen einer Strangmaterial-Wicklung von einer Trommel oder Spule.The invention relates to a device for removing a Strand material winding of a drum or spool.

Es kommt sehr häufig vor, daß Strangmaterial-Wicklungen auf Trommeln oder Spulen, deren Kern bearbeitet und ausgewuchtet ist, in Bereichen nicht korrekt gewickelt sind oder daß das Strangmaterial, beispielsweise Kupferdraht, Risse aufweist. In diesen Fällen muß die Wicklung von den Trommeln oder Spulen entfernt werden. Da ein Abwickeln des Strangmaterials meist nicht möglich ist, geschieht dies z.Zt. mit Hammer und Meißel. Dabei kommt es an der Oberfläche des Trommel- oder Spulenkerns zu Beschädigungen, was eine Nachbearbeitung des Kerns und eine erneute Auswuchtung der Trommel oder Spule erfordert, damit beim erneuten Wickeln von Strangmaterial durch die Beschädigungen des Trommel- oder Spulenkerns keinerlei Beschädigungen des Strangmaterials auftreten. Das Abschlagen der Wicklung mit Hammer und Meißel sowie das Nacharbeiten des Trommel- oder Spulenkerns und das erneute Auswuchten der nachgearbeiteten Trommel oder Spule ist sehr zeitaufwendig und daher auch kostenintensiv.It is very common that strand material windings on Drums or bobbins whose core is machined and balanced is not wrapped correctly in areas or that the Strand material, such as copper wire, has cracks. In These cases must be the winding of the drums or coils be removed. Since unwinding of the strand material mostly is not possible, this is currently happening. with hammer and chisel. It comes on the surface of the drum or coil core damage, resulting in a post-processing of the core and a rebalancing the drum or spool requires doing so rewinding of strand material by the damage of the Drum or coil core no damage to the Strand material occur. The knocking off of the winding with Hammer and chisel as well as the reworking of the drum or chisel Spool core and rebalancing the reworked Drum or spool is very time consuming and therefore too expensive.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung der angegebenen Gattung zu schaffen, mit der die Wicklungen bzw. Restwicklungen von einer Trommel oder Spule relativ schnell entfernt werden können, wobei eine Nacharbeitung des Trommel- oder Spulenkerns und das erneute Auswuchten der nachgearbeiteten Trommel oder Spule nicht notwendig sind. The invention is therefore based on the object, a Device of the specified type, with which the Windings or residual windings of a drum or coil can be removed relatively quickly, with a rework the drum or spool core and re-balancing the reworked drum or coil are not necessary.

Diese Aufgabe wird erfindungsgemäß durch eine Vorrichtung mit den Kennzeichnungsmerkmalen des Patentanspruchs 1 gelöst.This object is achieved by a device solved with the characterizing features of claim 1.

Zweckmäßige Weiterbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Advantageous developments of the invention are in the Subclaims characterized.

Die erfindungsgemäße Vorrichtung zeichnet sich vor allem dadurch aus, daß durch den Schneidkopf das Strangmaterial relativ schnell von der Trommel oder Spule entfernt werden kann, wobei durch die besondere Ausbildung des Schneidkopfes auch keinerlei Beschädigungen auf dem Trommel- oder Spulenkern auftreten. Dies alles sorgt für eine enorme Kostenreduzierung durch die Zeitersparnis beim Entfernen der Wicklung bzw. Restwicklung und das Entfallen der Nachbearbeitung des Trommeloder Spulenkerns bzw. des erneuten Auswuchtens der Trommel oder Spule.The device according to the invention is distinguished above all characterized in that by the cutting head, the strand material can be removed relatively quickly from the drum or coil, whereby due to the special design of the cutting head also no damage on the drum or coil core occur. This all makes for a huge cost reduction by saving time when removing the winding or Residual winding and the elimination of the post-processing of the drum or Spool core or re-balancing the drum or Kitchen sink.

Mit der in den Figuren 2 und 3 dargestellten Vorrichtung 1 wird eine Strangmaterial-Wicklung 2 bzw. die Restwicklung von einer Trommel oder Spule 3 (siehe Fig. 1) mittels eines Schneidkopfes 4 mit einem durch einen elektromotorisch angetriebenen Exzenter 5 über einen Kreisbogen b beweglichen mehrschneidigen Messerteil 6 und einem am Motorgehäuse 7 befestigten feststehenden und ebenfalls mehrschneidigen Messerteil 8 entfernt, d.h. die Drähte des Strangmaterials werden durchtrennt. Dazu wird der Schneidkopf 4 in Querrichtung a der Wicklung 2 auf der Trommel bzw. der Spule 3 entlang der Wicklung 2 geführt. Die abgetrennten Drähte fallen dabei von der Trommel bzw. Spule 3 ab.With the device 1 shown in Figures 2 and 3 is a strand material winding 2 and the remaining winding of a drum or spool 3 (see Fig. 1) by means of a Cutting head 4 with a by an electric motor driven eccentric 5 via a circular arc b movable multi-bladed knife part 6 and one on the motor housing. 7 fixed fixed and also multi-bladed Knife part 8 removed, i. the wires of the strand material are severed. For this purpose, the cutting head 4 in the transverse direction a of the winding 2 on the drum or the coil 3 along the Winding 2 out. The severed wires fall from the Drum or coil 3 from.

Die Antriebsvorrichtung 9 der Vorrichtung 1 besteht aus einem in dem Motorgehäuse 7 angeordneten Motor 10, der eine am vorderen Ende 11 des Motorgehäuse 7 aus diesem hervorragende Spindel 12 vorzugsweise über ein Winkelgetriebe 13 mittels des Exzenters 5 antreibt. An der Spindel 12 ist das bewegliche Messerteil 6 auswechselbar angebracht.The drive device 9 of the device 1 consists of a arranged in the motor housing 7 engine 10, the one on front end 11 of the motor housing 7 from this excellent Spindle 12 preferably via an angle gear 13 by means of Exzenters 5 drives. On the spindle 12 is the movable Knife 6 mounted interchangeable.

Auch das am Motorgehäuse 7 angebrachte feststehende Messerteil 8 ist auswechselbar mit dem Motorgehäuse 7 verbunden.Also attached to the motor housing 7 fixed Blade 8 is interchangeable connected to the motor housing 7.

Zur einfacheren Handhabung der Vorrichtung 1 ist die Antriebsvorrichtung 9 mit dem Winkelgetriebe 13 ausgestattet. Es ist jedoch auch möglich, eine Antriebsvorrichtung 9 ohne Winkelgetriebe 13 zu verwenden.For easier handling of the device 1 is the Drive device 9 equipped with the angle gear 13. It However, it is also possible, a drive device 9 without Angular gear 13 to use.

Das bewegliche Messerteil 6 und das feststehende Messerteil 8 weisen jeweils eine Vielzahl kurzer Schneiden 14 auf. Die vordere Schneidkante 15 der Messerteile 6, 8 ist vorzugsweise entsprechend dem Kreisbogen b abgerundet. The movable blade part 6 and the fixed blade part 8 each have a plurality of short cutting edges 14. The front cutting edge 15 of the blade parts 6, 8 is preferably rounded off according to the arc b.

Um ein Schneiden der Wicklung 2 bis in die Ecken der Trommel oder Spule 3 zu gewährleisten, ist die Längsmittelachse 16 des Schneidkopfes 4 zur Längsmittelachse 17 der Antriebsvorrichtung 9 leicht schräg angeordnet.To cut the winding 2 into the corners of the drum or coil 3, is the longitudinal center axis 16 of the Cutting head 4 to the longitudinal central axis 17 of the drive device 9 arranged slightly obliquely.
