Double-operation process device and arrangement of this process device

Field of application of the invention

The invention is applicable in the cable industry and relates to a dual-operation draining device for draining a wire-like element in the reel and unwinding mode, in particular for twin-strand machines.

Characteristic of the known technical solutions

The common feature of the different processing machines used in the cable industry (pulling, stranding, insulating) is that the wire or line to be processed enters the machine from a coil placed in a drainage device. Depending on the requirements of the field of application, the drain device is a holding of several coils and in the course of a work cycle, the continuous feeding of the wire or the line of., The W coil in the machine enabling scaffolding or one suitable for the operation of a single coil, in general double-arm (ü-fönaige) device ·. Pur Doppelverse ilmaschinen, where separately arranged by the stranding machine coils are necessary, the number of which is identical to that of the wire-like elements to be stranded, both systems are suitable for drainage equipment. In practice, the drainage is generally carried out by coils of smaller dimensions (up to an edge diameter of at most 400 mm) and weight (at most 120 kg) with a discharge device with scaffolding design, while in coils with larger dimensions and weight of each wire, the drainage of Coils are carried out in separate process devices,

Several different basic operating modes of the drainage devices are known * In the cable industry, drainage devices of any basic construction are used, since the appropriate application areas differ depending on the cross section of the wires to be unwound.

Under the Amen-type coil-flow device, such a wire run-off device is known, the spool rotates freely on the on the horizontally mounted in the scaffold flow axis or scaffold ¹ in the sequence together with the stored at both ends of the axis rotates. During the working cycle, the wire is pulled through the stranding machine, while the thus-rotated coil is braked by a constant moment. This solution allows undisturbed operation when the cross section of the wire to be unwound is large compared to the size of the coil. "For a wire with a smaller cross section, the coil, which has a large mass, can not turn the wire when the stranding machine starts up and the wire expands When turning off the stranding machine, the bobbin can not stop synchronously with the sizing machine without a corresponding brake torque, but continues to rotate, resulting in damage to the wire. "

In order to overcome the above problems, a wire tension regulator is used, wherein the force produced by the wire running in the wire controls the wire tensioner or thereby the brake of the pick-up device. However, if the applied wire tension regulator only acts on the brake of the discharge unit or of the coil, the executable wire cross-sectional area can only be broadened in a small WbQ .

Since a decrease in the braking effect is insufficient when running wires with a small cross-section, the coil must be driven at startup, or acceleration, to tearing

to prevent the wire. The development of technology in recent years has enabled the spool to be driven and braked by complicated and costly constructions. "With these constructions, although the spreader is capable of operation across the entire wire gauge area, the cost of running the spout is greatly increased.

In the operating on the principle of Abgewkelns working the spindle holding the spool and the spool are fixed * The unwinding of the wire from the spool rotatably mounted at the other end of the axis, by the towed by the wire rope wire unwinding arm by «this Solution is the Drehiaasse not significant, so start and stop when draining wires with even very small cross section no problem. The unwinding of wires with larger cross sections, however, already causes difficulties. These wires resist the bending stress resulting from the puncture principle due to their rigidity, and the force created in the wire deforms the unwinding arm. The stiffness of the Abwickelarraes can not be increased arbitrarily because of the increase in the rotational mass,.

It is necessary to use a wire-conducting member between the cable-processing machine and the discharge devices to change the direction of the wire-like elements to be unwound. The wire-conducting member is generally made of lute and conveniently mounted rollers, but to safely guide the wire-like members and prevent them from falling off the rollers, it is also common to use other structural members.
