STIMMT DBEEEIN MIT ATJSLEGESCBiRIFT 1 049 742 (B DOES AGREE WITH ATJSLEGESCBiRIFT 1 049 742 (B. 36609 36609 VU /73)VU / 73)

Die Erfindung bezieht sich auf Verseilmaschinen für Draht, bei welchen zwischen zwei oder mehreren um eine waagerechte Achse drehbaren Jochen ein Anzahl Spulen angeordnet sind, welche drehbar auf je einem Achs stumpf paar sitzen, und wobei von jedem Paar ein Achsstumpf rückziehbar angeordnet ist.The invention relates to stranding machines for wire, in which between two or more A number of coils are arranged around a horizontal axis rotatable yokes, which are rotatable on each a stub axle pair sit, and each pair of a stub axle is arranged retractable.

.Es-sind bereits Verseilmaschinen bekannt, bei welchen die Spulen drehbar in Rahmen gelagert und mit diesen in einem sich drehenden Rohr od. dgl. gehalten sind. Bei diesen bekannten Verseilmaschinen ist jedem Rahmen eine Plattform zugeordnet, welche angehoben werden kann, bis sie mit einer im Rahmen sitzenden leeren Spule in Wirkverbindung kommt, so daß sie diese aus dem Rahmen herausheben und am Boden absetzen kann. Die entladene Plattform wird dabei mit einer gefüllten Spule beladen und zum Rahmen zurückgeführt, um die volle Spule in diesen einzusetzen. Eine derartige Verseilmaschine weist einen komplizierten Aufbau auf und hat den Nachteil, daß für das Auswechseln von leeren durch volle Spulen ein erheblicher Zeitaufwand erforderlich ist, wobei jedesmal die Maschine stillgesetzt werden muß.. There are already known stranding machines in which the spools are rotatably mounted in frames and with these are held in a rotating tube or the like. In these known stranding machines, everyone is A platform is assigned to the frame, which can be raised until it is seated in the frame empty coil comes into operative connection so that it can lift it out of the frame and set it down on the ground. The unloaded platform is with it A full bobbin is loaded and returned to the frame for the full bobbin to be inserted into it. Such a stranding machine has a complicated structure and has the disadvantage that empty bobbins can be replaced by full bobbins a considerable expenditure of time is required, and each time the machine has to be shut down.

Es wurde zwar weiterhin vorgeschlagen, die Spulen in einer Verseilmaschine auf rückziehbaren Achsen anzuordnen und jede Spule mit einer von Hand betätigten Vorrichtung zu versehen, mittels welcher die Achse aus der Spule herausgezogen werden kann. Solche von Hand betätigte Vorrichtungen, welche dauernd an einer vorbestimmten Stelle des Verseilkörpers angeordnet sind, müssen aber relativ kleine Abmessungen und ein geringes Gewicht aufweisen,It was also proposed that the coils in a stranding machine on retractable axes to arrange and to provide each coil with a manually operated device by means of which the Axle can be pulled out of the spool. Such manually operated devices which are permanently arranged at a predetermined point of the stranded body, but must be relatively small Have dimensions and light weight, ' wenn die bewegten Massen nicht übermäßig groß werden sollen. Deshalb können. Spulen von großem Gewicht nur unter Schwierigkeiten in derartigen Verseilmaschinen verwendet werden. Diese von Hand betätigten Rückzieh vor richtungen erfordern außerdem zu ihrer Betätigung einen erheblichen Zeitaufwand, da zu diesem Zweck die Maschine unbedingt stillgesetzt werden, muß.'if the moving masses are not excessively large should be. Therefore can. Coils of great weight only with difficulty in such Stranding machines are used. These manually operated retraction devices also require a considerable amount of time to operate them, since the machine is essential for this purpose must be stopped.

Gemäß der Erfindung werden die Nachteile der bekannten Verseilmaschinen in erster Linie dadurch vermieden und. das Auswechseln der Spulen dadurch verbessert, daß eine Rückziehvorrichtung für die Achsstümpfe und eine Spulenausziehvorrichtung für die Spulen vorgesehen ist, wobei die Anordnung soAccording to the invention, the disadvantages of the known stranding machines are primarily thereby avoided and. the replacement of the coils improved in that a retractor for the Stub axles and a bobbin pull-out device for the bobbins is provided, the arrangement so , getroffen ist, daß die im Joch geführten rückziehbaren Achsstümpfe in Flucht mit der Rückziehvorrichtung überführbar sind, wobei letztere einmal als Antriebsvorrichtung dargestellt, mittels welcher sie nach einem benachbarten Achsstumpf hin und von diesem wegzubewegen ist,;-und dann als Kupplungsvorrichtung betätigbar ist, mittels welcher sie jeweils mit einem der Achsstümpfe zn kuppeln und abzukuppeln ist, derart, daß die Rückziehvorrichtung, wenn sie sich in, is taken that the retractable stub axles guided in the yoke are in alignment with the retraction device are transferable, the latter shown once as a drive device, by means of which they after a adjacent stub axle is to be moved towards and away from this, - and then as a coupling device can be operated, by means of which it can be coupled and uncoupled with one of the stub axles zn, such that the retractor when it is in

Dabei ist es besonders vorteilhaft, wenn die rückziehbaren Achsstümpfe in Gehäusen sitzen, welche in Hülsen von einem derare formed that they rotate the yokes and the stub axles connected to them during the Allow coupling process. It is particularly advantageous if the retractable stub axles in Housings sit, which are in sleeves of one of the Joche gehalten sind und die über das Joch hinausrage^ und wenn die Gehäuse bzw. die Rückziehvorrichtung mit T-förmigen Ansätzen bzw.

Claims

1 102 close to the lugs 18 of the plates 17. Each of the two outwardly widened ends 103 of the safety ring 102 contains a safety switch 104, one of which is pushed by the lug 18 of a protruding housing before the safety arm pushes it inward. The switch, when pressed, closes a circuit to open the main circuit of the machine. The protective or safety ring sits on a pair of retaining posts 10, to which it is connected by means of a linkage 106, which allow an axial retraction of the safety ring 102 from its normal running position into the retracted position, which can be verified by the dashed lines in FIG. Stop pins 107 attached to the post 105 limit the positions of the linkage 106 as well as those of the safety ring 102. It is necessary to retract the safety ring to an inoperative position during the spool replacement process because the retractable stub axles and their housings are in the extended positions and would damage the "security ring if it were not withdrawn. Fig. 1 shows an Entde of the safety ring 102 in its effective positions. The ends of the safety ring at ts ring are widened outwards in order to eliminate the possibility of damage to these ends by the lugs 18. During the described operation of the machine, the Jodhel are driven very slowly in order to bring each of the cams 90 one after the other into contact with the push button 91. Each time this occurs, the head 22 is pushed forward to grasp a lug 18 and the head is withdrawn to retract a housing with its retractable axle stub and reveal an empty spool which then falls onto the platter below and out the machine is rolled out when the yokes 1 continue to rotate, through the contact or the action of the tube 3, which is provided until itelbar behind the empty bobbin. During this unloading operation, the latches 32 are retained in their innermost positions. When laying or inserting full bobbins into the machine, the bars are held in their retracted positions. A supply of full bobbins is kept ready for the exchange process; a full bobbin is released for entry into the loading position each time a retracted plate 17 actuates a limit switch 94. The full coil is opened when entering the loading position. associated stub axle because the retracted stub axle of this pair has returned to its working position by the forward movement of head 22, which head is pushed forward and retracted by the cooperation of the corresponding node 90 with the push button control valve 92. Although the automatic working of the head 22 enables better utilization of time for changing the coils, a substantial time saving can be achieved in comparison to earlier or older methods if the working of the head is controlled manually. Although the invention has mainly been described in connection with a single set of spools, the stranding machine will generally have an array of spool seeds. For example, there may be six sets of coils and six coils connected in one set, with all sets axially aligned 742 with one another. Each reel will have a guide for guiding the wire away from this reel to a bearing plate through which the wire is guided to a tool. PATENT CLAIMS:
