Abstract

The profile material (5), especially metallic wire, is firstly fed in a loop over a deflection roller (6) and only then fed to the processing machine. The freely rotatable deflection roller is supported by a swivel arm (7) which, in an upper boundary position, with a shorter loop length, switches on a drive for the reel (1) and, in its lower boundary position, with a greater loop length, switches it off again. Due to this device, very even uncoiling speeds with low tensile stress can be achieved even with heavy reels. <IMAGE>

Description

Die Erfindung betrifft eine Abwickelvorrichtung für biegeempfindliches Profilmaterial, insbesondere Me­talldraht, das mit einer geringen Zugkraft durch eine das Material verarbeitende Maschine abgezogen wird. Insbesondere soll diese Abwickelvorrichtung für Me­talldraht mit rundem oder polygonalem Profil verwendet werden, der in der verarbeitenden Maschine spangebend verarbeitet und auf kurze Längen abgeschnitten wird, beispielsweise zur Herstellung von Buchsen, Kontakt­stiften und dergleichen.The invention relates to an unwinder for bend-sensitive profile material, in particular metal wire, which is drawn off with a low tensile force by a machine processing the material. In particular, this unwinding device is to be used for metal wire with a round or polygonal profile, which is machined in the processing machine and cut to short lengths, for example for the production of sockets, contact pins and the like.

Eine solche Abwickelvorrichtung besteht aus einer Haspel mit dem Profilmaterial, die drehbar mit horizontal angeordneter Drehachse in einem größeren Abstand, mindestens von zehn Haspeldurchmessern, von der verarbeitenden Maschine angeordnet ist.Such an unwinder consists of a reel with the profile material, which is rotatably arranged with a horizontally arranged axis of rotation at a greater distance, at least ten reel diameters, from the processing machine.

Das Profilmaterial läuft von der Haspel ab und wird durch den Zug allmählich gestreckt.The profile material runs off the reel and is gradually stretched by the train.

Die Verarbeitungsmaschine übt zwar auf das Profilmate­rial eine gewisse Zugkraft aus, die aber nicht ausreicht, um die schwere Haspel zu drehen. Man ist deshalb gezwungen, der Haspel einen eigenen elektromo­ torischen Antrieb zuzuorden. Dabei muß dann die Ablaufgeschwindigkeit des Profilmaterials von der Haspel exakt der Einzugsgeschwindigkeit der verarbei­tenden Maschine angepaßt werden. Diese Anpassung ist nur durch relativ komplizierte Regler möglich. Dennoch ist es in der Praxis unvermeidlich, daß die Ablaufge­schwindigkeit des Profilmaterials von der Haspel kurzzeitigen Schwankungen unterworfen ist, die sich als entsprechende Schwankungen in der Zugspannung im Profilmaterial auswirken. Dadurch wird nicht nur die gleichmäßige Verarbeitung des Profilmaterials in der anschließenden Maschine gestört, sondern es können auch Knicke durch unregelmäßige Streckung des Profil­materials die Folge sein.The processing machine exerts a certain tensile force on the profile material, but this is not sufficient to turn the heavy reel. One is therefore forced to make the reel its own electromo assign toric drive. The running speed of the profile material from the reel must then be adapted exactly to the feeding speed of the processing machine. This adjustment is only possible with relatively complicated controllers. Nevertheless, in practice it is inevitable that the running speed of the profile material from the reel is subject to short-term fluctuations, which act as corresponding fluctuations in the tensile stress in the profile material. This not only disrupts the uniform processing of the profile material in the subsequent machine, but it can also result in kinks due to irregular stretching of the profile material.

Der Erfindung liegt die Aufgabe zugrunde, eine Abwickelvorrichtung der vorgenannten Art so weiterzu­entwickeln, daß der Transport des Profilmaterials mit konstanter Geschwindigkeit erfolgt und die von der verarbeitenden Maschine ausgeübte Zugkraft keinen Schwankungen unterworfen ist.The invention has for its object to further develop an unwinding device of the aforementioned type so that the transport of the profile material takes place at a constant speed and the tensile force exerted by the processing machine is not subject to fluctuations.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Kennzeichens des Anspruchs 1 gelöst.This object is achieved by the features of the characterizing part of claim 1.

Der Schwenkarm und die Umlenkrolle lassen sich, im Gegensatz zur Haspel, sehr leicht ausbilden. Auch das Schwenklager für den Schwenkarm läßt sich praktisch reibungsfrei ausbilden. Es wird folglich für das Anheben der Umlenkrolle mit Schwenkarm, entgegen der auf diese Teile wirkenden Schwerkraft, nur eine sehr geringe Zugspannung im Profilmaterial benötigt, die ohne Schwierigkeiten von den üblichen Verarbeitungs­maschinen aufgebracht werden kann.In contrast to the reel, the swivel arm and the deflection roller are very easy to form. The swivel bearing for the swivel arm can also be designed to be practically frictionless. It is consequently only a very low tension in the profile material required for lifting the deflection roller with swivel arm, against the gravity acting on these parts, which can be applied without difficulty by the usual processing machines.

Durch die von der verarbeitenden Maschine ausgeübte Zugkraft wird die Umlenkrolle mit ihrem Schwenkarm langsam und gleichmäßig aufwärts geschwenkt, wobei sie - bei stillstehender Haspel - die benötigte Länge des Profilmaterials freigibt.Due to the pulling force exerted by the processing machine, the deflection roller with its swivel arm slowly and evenly swung upwards, releasing the required length of the profile material when the reel is at a standstill.

Sobald die Umlenkrolle bzw. der diese tragende Schwenkarm eine vorbestimmte obere Grenzlage erreicht hat, schaltet der dann ansprechende Endlagenschalter den Antrieb für die Haspel ein. Dieser Antrieb wird selbstverständlich so bemessen, daß sich eine größere Umfangsgeschwindigkeit an der Haspel ergibt, als die von der verarbeitenden Maschine benötigte Einzugsge­schwindigkeit.As soon as the deflection roller or the swivel arm carrying it has reached a predetermined upper limit position, the responsive limit switch then switches on the drive for the reel. This drive is of course dimensioned so that there is a greater peripheral speed on the reel than the retraction speed required by the processing machine.

Während nun die Haspel mit dieser größeren Ge­schwindigkeit eine gewisse Länge des Profilmaterials freigibt, von der nur ein Teil weiterhin gleichmäßig in die verarbeitende Maschine eingezogen wird, senkt sich der Schwenkarm mit der Umlenkrolle wieder ab und nimmt dadurch, daß sich sein horizontaler Abstand von der verarbeitenden Maschine vergrößert, die Differenz­länge auf.Now, while the reel releases a certain length of the profile material at this higher speed, only a part of which is still being drawn evenly into the processing machine, the swivel arm with the deflection roller lowers again, thereby reducing its horizontal distance from the processing machine Machine enlarged, the difference length on.

Wenn der Schwenkarm mit Umlenkrolle dann eine untere Grenzlage erreicht hat, schaltet der Endlagenschalter den Antrieb für die Haspel wieder aus. Das hat zur Folge, daß jetzt, bei stillstehender Haspel, die Umlenkrolle wieder aufwärts und nach vorn gezogen wird, wobei sie das von der verarbeitenden Maschine benötigte Profilmaterial freigibt.When the swivel arm with deflection roller has reached a lower limit position, the limit switch switches the drive for the reel off again. The result is that now, with the reel at a standstill, the deflection roller is pulled upwards and forwards again, releasing the profile material required by the processing machine.

Das Material wird also letztlich über eine Schleife veränderlicher Länge zur verarbeitenden Maschine geleitet.The material is ultimately fed to the processing machine via a loop of variable length.

Die Lagerung der Haspel kann auf verschiedene Weise erfolgen. Vorzugsweise ist jedoch eine Lagerung durch zwei Tragwalzen vorgesehen, die im Abstand voneinander und parallel zueinander mit horizontal angeordneten Mittelachsen in einer Sockelplatte gelagert sind.The reel can be stored in different ways. However, storage by two support rollers is preferably provided, which are spaced apart and are mounted parallel to each other with horizontally arranged central axes in a base plate.

Vorzugsweise ist bei einer solchen Anordnung die eine der beiden Tragwalzen angetrieben und überträgt die Antriebsbewegung bzw. das antreibende Drehmoment auf den Umfang der Haspel.In such an arrangement, the one of the two support rollers is preferably driven and transmits the drive movement or the driving torque to the circumference of the reel.

Bei dieser Ausbildung ist der die Umlenkrolle tragende Schwenkarm vorzugsweise in der Sockelplatte schwenkbar gelagert, und zwar auf der der verarbeiten­den Maschine abgewandten Seite der Sockelplatte.In this embodiment, the swivel arm carrying the deflection roller is preferably pivotally mounted in the base plate, on the side of the base plate facing away from the processing machine.

Der Endlagenschalter kann an beliebiger Stelle so angeordnet werden, daß er entweder durch den Schwenk­arm oder durch die Umlenkrolle betätigt wird. In diesem Falle benötigt man im allgemeinen einen zweiteiligen Endlagenschalter, also einen Schalter in der oberen und einen in der unteren Grenzstellung.The limit switch can be arranged at any point so that it is operated either by the swivel arm or by the guide roller. In this case, you generally need a two-part limit switch, i.e. a switch in the upper and one in the lower limit position.

Vorzugsweise ist jedoch vorgesehen, daß ein einziger Endlagenschalter mit zwei Grenzstellungen im Schwenk­lager des Schwenkarms angeordnet ist.However, it is preferably provided that a single limit switch with two limit positions is arranged in the swivel bearing of the swivel arm.

Um das von der Haspel ablaufende Profilmaterial keinen überflüssigen Biegungen zu unterziehen, wird vorzugs­weise vorgeschlagen, daß der wirksame Durchmesser der Umlenkrolle zwischen der Hälfte und dem Eineinhalb­fachen des Durchmessers der Haspel liegt. Bei einer solchen Bemessung wird das ablaufende Profilmaterial, sowohl bei noch voller Haspel als auch bei fast leerer Haspel, weitgehend geschont und es werden Knickbil­dungen verhindert.In order not to subject the profile material running from the reel to unnecessary bends, it is preferably proposed that the effective diameter of the deflection roller be between half and one and a half times the diameter of the reel. With such a design, the running profile material is largely protected, both when the reel is still full and when the reel is almost empty, and buckling is prevented.

Die Erfindung wird nachstehend in einem Ausführungs­beispiel anhand der Zeichnung näher erläutert. Dabei zeigt:

  • Fig. 1 eine schematisch vereinfachte Darstel­lung einer erfindungsgemäßen Vorrichtung in der einen Grenzlage, und
  • Fig. 2 die Vorrichtung gemäß Fig. 1, jedoch in der anderen, oberen Grenzlage der Um­lenkrolle.
The invention is explained in more detail in an exemplary embodiment with reference to the drawing. It shows:
  • Fig. 1 is a schematic simplified representation of a device according to the invention in the one limit position, and
  • Fig. 2 shows the device of FIG. 1, but in the other, upper limit position of the guide roller.

Wie man sieht, ruht die Haspel 1 auf zwei Tragwalzen 2 und 3, die, wie in der Zeichnung angedeutet, oberhalb einer Sockelplatte 4 angeordnet und gelagert sind. Die eine der beiden Tragwalzen kann durch einen Elektromo­tor (nicht dargestellt) angetrieben werden.As can be seen, the reel 1 rests on two support rollers 2 and 3, which, as indicated in the drawing, are arranged and mounted above a base plate 4. One of the two support rollers can be driven by an electric motor (not shown).

Auf der einen (in der Zeichnung rechten) Seite der Sockelplatte 4 ist bei 8 ein Schwenkarm 7 schwenkbar gelagert, der an seinem anderen Ende frei drehbar eine Umlenkrolle 6 trägt.On one side (on the right in the drawing) of the base plate 4, a pivot arm 7 is pivotally mounted at 8 and carries a deflecting roller 6 at its other end in a freely rotatable manner.

Das Profilmaterial 5 läuft von der Haspel 1 unten ab und wird über den Umfang der Umlenkrolle 6 in einer Schleife wieder zurück und in Richtung des Pfeiles 9 zu der verarbeitenden Maschine (nicht dargestellt) geführt. Der im Lager 8 schwenkbar gelagerte und die Umlenkrolle 6 tragende Schwenkarm 7 kann in Richtung des Pfeiles 10 aufwärts oder abwärts geschwenkt werden. Dabei verringert sich der Abstand der Dreh­achse der Umlenkrolle 6 von der Haspel und vor allem von der (nicht eingezeichneten) verarbeitenden Ma­schine, so daß die Schleife im Profilmaterial insge­samt kürzer wird.The profile material 5 runs from the reel 1 below and is looped back over the circumference of the deflection roller 6 and in the direction of arrow 9 to the processing machine (not shown). The pivot arm 7, which is pivotably mounted in the bearing 8 and carries the deflection roller 6, can be pivoted upwards or downwards in the direction of the arrow 10. The distance of the axis of rotation of the deflection roller 6 from the reel and above all from the processing machine (not shown) is reduced, so that the loop in the profile material becomes shorter overall.

Die obere Grenzlage des Schwenkarms 7 - und der Umlenkrolle 6 - sind in Fig. 1 gestrichelt und in Fig. 2 ausgezogen dargestellt, während in Fig. 2 die untere Grenzlage 6, 7 der genannten Teile gestrichelt dargestellt ist.The upper limit position of the swivel arm 7 - and the deflection roller 6 - are shown in broken lines in FIG. 1 and in solid lines in FIG. 2, while in FIG. 2 the lower limit positions 6, 7 of the parts mentioned are shown in broken lines.

Wie man sieht, wird das Profilmaterial 5 in einem sanften weitgestreckten Bogen von der Haspel zur Umlenkrolle und von dieser ohne abrupte Änderungen der Krümmung wieder nach links, in Richtung des Pfeiles 9, geführt.As can be seen, the profile material 5 is guided in a gentle, elongated arc from the reel to the deflection roller and from there again to the left, in the direction of arrow 9, without abrupt changes in the curvature.

Der im Schwenklager 8 des Schwenkarms 7 angeordnete Endlagenschalter (nicht dargestellt) schaltet jeweils in der in Fig. 2 dargestellten oberen Grenzlage den Antrieb für die Haspel ein und in der unteren Grenzlage wieder aus.The limit switch (not shown) arranged in the pivot bearing 8 of the pivot arm 7 switches the drive for the reel on in the upper limit position shown in FIG. 2 and off again in the lower limit position.

Während also im Betrieb die Haspel 1 abwechselnd angetrieben wird und dann wieder stillsteht, und während sich der Schwenkarm 7 mit der Umlenkrolle 6 abwechselnd aufwärts und dann wieder abwärts bewegt, erfolgt der Vorschub des Profilmaterials 5 in Richtung des Pfeiles 9 mit konstanter Geschwindigkeit. Es ist nur ein sehr geringer Bandzug erforderlich, um die Umlenkrolle 6 mit Schwenkarm 7 aufwärts zu ziehen bzw. zu halten, weil man diese Teile aus sehr leichten Werkstoffen herstellen kann.So while the reel 1 is alternately driven during operation and then stops again, and while the swivel arm 7 with the deflection roller 6 alternately moves up and then down again, the profile material 5 is fed in the direction of arrow 9 at a constant speed. Only a very slight band tension is required to pull or hold the deflection roller 6 with the swivel arm 7 upwards, because these parts can be made from very light materials.
