Description

Die Erfindung betrifft eine kontinuierlich arbeitende Abwickeleinrichtung, mit deren Hilfe Draht fortlaufend von Spulen oder zylindrischen, faßartigen Behältern abgewickelt werden kann.The invention relates to a continuously operating unwinding device, with the aid of which wire continuously can be unwound from spools or cylindrical, barrel-like containers.

Es sind bereits derartige Einrichtungen bekanntgeworden, bei welchen das Ende und der Anfang des Drahtes zweier insbesondere über Kopf abgezogener Trommeln miteinander verbunden sind. Zwischen diesen Trommeln ist eine Haltevorrichtung in Form einer in sich federnden Klemme vorgesehen, welche das Verwirren der zwischen den Trommeln verlaufenden Drahtschlinge verhindert, jedoch anläßlich der in Verbindung mit dem Überspringen des Drahtes auf die nächste Trommel auftretenden Zugbeanspruchung den Draht aus ihren federnden Lippen freigibt.Such facilities have already become known, in which the end and the beginning of the Wire of two drums, in particular drawn off overhead, are connected to one another. Between these Drums are provided with a holding device in the form of a resilient clamp, which prevents tangling the wire loop running between the drums prevents, however, on the occasion of the connection the tensile stress that occurs when the wire skips onto the next drum Releasing wire from her springy lips.

Demgegenüber bezieht sich die Erfindung auf eine kontinuierlich arbeitende Abwickeleinrichtung, deren wesentliches Kennzeichen darin zu erblicken ist, daß die Halteeinrichtung aus einer sich über die gesamte Bewicklungslänge einer Trommel und parallel zur Trommel erstreckenden Scheide mit aneinandergepreßten Federlippen besteht, wobei das Drahtende der auslaufenden Trommel an dem von der Abzugsstelle des Drahtes abgelegenen Ende der Scheide durch die Lippen hindurch in den Hohlraum der Scheide einführbar, insbesondere unter Mitwirkung eines vor Trommelwechsel des Drahtes von Hand entfernbaren Steckstiften um 90° umlenkbar und anschließend im Innern der Scheide bis an den der Abzugsstelle des Drahtes zunächst gelegenen Anfang der folgenden Trommel heranführbar ist.In contrast, the invention relates to a continuously operating unwinding device, whose An essential characteristic is that the holding device consists of one over the entire Wrapping length of a drum and sheath extending parallel to the drum with pressed together Consists of spring lips, with the wire end of the expiring drum at the point of the withdrawal point of the Wire distal end of the vagina can be inserted through the lips into the cavity of the vagina, in particular with the assistance of a pin that can be removed by hand before the wire drum is changed can be deflected by 90 ° and then inside the sheath up to the point where the wire is withdrawn first located beginning of the following drum can be brought up.

Der Vorteil dieser Einrichtung gegenüber der vorgenannten bekannten Anordnung ist vor allem darin zu erblicken, daß die Schlaufe zwischen den beiden Trommeln während der ganzen Zeit des Überwechseins des Drahtes von der einen auf die andere Trommel unter Spannung gehalten ist und damit für ein nach dem Ausspringen des Drahtes aus der in sich federnden Klemme noch eintretendes Verwirren keine Möglichkeit mehr besteht.The advantage of this device over the aforementioned known arrangement is above all in it see that the loop between the two drums during the entire time the Wire from one to the other drum is kept under tension and thus for one after the other There is no possibility of the wire jumping out of the resilient terminal or confusion there is more.

In weiterer Ausgestaltung des Grundgedankens der Erfindung sind die Trommeln von die Ballonbildung des ablaufenden Drahtes begrenzenden Behältern umgeben, wobei die Scheide im Innern des Behälters herausnehmbar befestigt ist und Federklammern trägt, mit denen sie in Durchbrüche der Behälterwand einhängbar ist.In a further embodiment of the basic idea of the invention, the drums are balloon formation of the outgoing wire bounding containers, the sheath inside the container being removable is attached and carries spring clips with which they can be suspended in openings in the container wall is.

Die Erfindung und deren besondere Merkmale im Vergleich zu den bekannten Einrichtungen sind nachstehend an Hand der Zeichnung noch näher erläutert. In dieser zeigenThe invention and its particular features in comparison with the known devices are as follows explained in more detail with reference to the drawing. In this show

Die in den Fig. 1 und 2 dargestellte, an sich bekannte Einrichtung zum fortlaufenden Abwickeln von Draht aus zylindrischen Behältern zeigt einen Körper mit zwei Kegeln 1 und 2, welche an ihren Spitzen 3 abgestumpft sind und zwischen zwei Erzeugnissen je eine öffnung 4 besitzen. Diese Öffnungen sind durch zwei Wände 5 verbunden, zwischen welchen ein Durchgang für einen von dem einen oder anderen Kegelstumpf geförderten Draht zum anderen Kegelstumpf frei bleibt. Gleichachsig zu diesen Kegeln und unterhalb derselben sind zwei faßartige Behälter 6 und 7 angeordnet, die abwechselnd abgehaspelt werden. Einer dieser Behälter trägt einen äußeren Mantel 8, der eine Trommel 9 umschließt, wobei sich der Draht zwischen dem Zylinder 8 und der Trommel 9 befindet. Gegebenenfalls kann auf der Trommel 9 eine zylindrische Verlängerung 10 angebracht sein. Dieser AnsatzlO trägt eine Scheibell von größerem Durchmesser als jenem der Trommel 9, die um eine mittlere Achse umläuft. Die äußere Hülse 8 des Behälters kann durch einen Zylinder 12 gleichfalls verlängert werden. Über dem Doppelkegelkörper ist eine Walze 13 so angebracht, daß die durch den oberen Spalt zwischen den beiden Wänden 5 gelegte Ebene diese Walze tangiert. Zur Rückführung des Drahtes dient eine beweglich auf dem Gestell gelagerte Rolle 14. Die Arbeitsweise dieser bekannten Einrichtung ist folgende:The known device shown in FIGS. 1 and 2 for the continuous unwinding of wire from cylindrical containers shows a body with two cones 1 and 2, which are truncated at their tips 3 and each have an opening 4 between two products. These openings are connected by two walls 5 , between which a passage remains free for a wire conveyed by one or the other truncated cone to the other truncated cone. Coaxially to these cones and below the same two barrel-like containers 6 and 7 are arranged, which are alternately unreeled. One of these containers carries an outer jacket 8 which encloses a drum 9 , the wire being located between the cylinder 8 and the drum 9 . If necessary, a cylindrical extension 10 can be attached to the drum 9. This approach 10 carries a disk of larger diameter than that of the drum 9, which rotates around a central axis. The outer sleeve 8 of the container can also be extended by a cylinder 12. A roller 13 is mounted above the double cone body in such a way that the plane laid through the upper gap between the two walls 5 is tangent to this roller. A roller 14 movably mounted on the frame is used to return the wire. The mode of operation of this known device is as follows:

Claims

Disc 11 is set in rotation under the tension of the wire by its tangential friction and unwinds it due to its inertia. For a very high unwinding speed of the wire, it may be necessary that the disk is kept continuously in rotation in such a way that its tangential speed is greater than the wire speed. In this case, the disc can be driven in a known manner by an electric motor which is housed inside the extension piece 10. The extension cylinder 12 of the drum 9 of the container is intended to prevent the wire from forming a balloon. The wire enters the interior of the cone 1, is passed through the opening 3 and runs over the roller 13 movable on its axis, is then turned by the roller 14 and goes to the processing machine. While the container 6 is being emptied, a full container 7 is brought under the cone 2; the lower end of the wire from the container 6 and the upper end of the wire from the container 7 are connected by a joint 15, for example. When the last turn emerges from the container 6, the wire goes from the cone 1 through the space between the walls 5 and continues to roll out of the container 7 without the operator having to do this. Accordingly, this process takes place continuously without any delay in the wire feed. If the wire to be reeled is a wire composed of several threads, loops can occur, which can give rise to breaks in the later stages of manufacture, which must be avoided. In order to avoid the formation of loops, the unwinding wire must be kept under a certain, inherently low tension at all times. When a container is normally emptied, the weight of the wire and the presence of wire windings in the container are sufficient to provide this tension; but when the last turn of the container is unwound, the wire lies parallel to the vertical end which was previously connected to the following container. At this moment the wire can easily form a figure-of-eight loop, as indicated in FIG. According to the invention, this disadvantage is avoided by a holding device which consists of a sheath 16 extending over the entire winding length of a drum 9 and parallel to it, with spring lips 17 pressed against one another. Before the wire is taken up in a container, the end of the wire coming out of this is inserted into the sheath 16 with the feed head at a standstill, at the lower end of which a detachable pin 18 is attached. The sheath 16 is removably attached inside the container 6, 7 and carries spring clips 19 with which it can be suspended in openings 20 in the container wall. The free end of the wire that protrudes from the top of the sheath 16 is then tightened in order to eliminate the slack that occurs between the dispensing head and the detachable pin 18. Then, when the dispensing head is removed and the wire begins to deposit in the container, the pin 18 is withdrawn. When the last turn is wound, the wire rises along the slot of the sheath 16, the wire being held back by the spring lips 17 in such a way that it is under a tension which is sufficient to prevent the formation of loops.
