Description

[0001] The object of the invention is autonomous device for winding cable wires that cooperates with various cutting-stripping machines without transferring control signals between the device and cutting-stripping machine.

[0002] Winding devices that are currently available on the market do not comprise a detecting-buffering module and hence are dedicated for specific cutting-stripping machines, with which they can exchange, via signal wire, control signals that are necessary to select the correct operation parameters of the winding device. The control signals that are exchanged include e.g. transport speed of the cable through the cutting-stripping machine, current position of the cable, length of the cable, information regarding current cable displacement or stopping the cable to perform stripping and processing operation, or information about retracting the cable to perform the operation of removing the outer sheath. Current cutting and stripping devices manufacturers do not allow to exchange the information between cable winding devices except devices of their own manufacture or dedicated cable winding devices produced by other manufacturers, which means that the clients must use winding devices specified by the cutting-stripping machine manufacturer.

[0003] On the market, there are also winding devices available that comprise, as an additional equipment, a module equipped with sensors that provide information on the speed of the cable being fed by the cutting-stripping machine, but they are not equipped with buffering module that would "store" the excess of the cable when the winding plate starts and release the stored cable when the cutting-stripping machine stops feeding the cable. Buffering module is necessary for winding cables that are fed at a feed rate above about 1 m/s since it eliminates delay during starting and stopping of the winding plate.

[0004] Moreover, clients often need to use one winding device for two, three different cutting-stripping machines to freely shape their manufacturing capabilities and to optimally plan the loading and production order for every cable processing line, and, as it is clear from the above, this would force them to buy a whole set of devices.

[0005] The US patent specification US3951355A discloses an automatic cable winding apparatus comprising a traverse arm mounted to the traverse block sliding on a traverse base that guides cables to be wound on the drum and provided near the top thereof with guide rollers guiding said cables while supporting them from the upper and the lower sides thereof and a presser roller pressing the cables sideways, a device giving pressing force to said traverse arm, proximity switches detecting that the cables are wound up to the vicinity of the flange of the drum, a rotation angle detector which causes said traverse base to stop by the detection signals generated from said proximity switches and detects the rotation angle of the drum, another device for quickly advancing and retracting said traverse block relative to the flanges of the drum when said rotation angle detector detects that the drum has been rotated by a predetermined angle, and a device for raising the traverse apparatus by the height of the outer diameter of the cable every time a new layer of cable is wound on the drum.

[0006] International patent application WO2015113763A1 discloses a laying arm (27) for an apparatus (1) for helically winding an endless material (3) that is to be wound up, in which a winding drum (5) is rotationally driven. The laying arm (27) transfers the material (3) to be wound up to the winding drum (5) when the laying arm (27) performs an especially substantially linear back-and-forth laying motion. According to the invention, in a contact zone (38) which lies at the end (33) of the laying arm closer to the winding drum and which faces a sidewall flange (11a, 11b) of the winding drum (5), the laying arm (27) comes in direct contact, in particular in direct sliding contact, with said sidewall flange (11a, 11b), especially when the laying arm performs a turning operation. Furthermore, a distance sensor (36), such as a contactor (37), which is located at the end of the laying arm closer to the winding drum, emits a control signal, such as a turning operation-triggering signal, at least when the end (33) of the laying arm closer to the winding drum reaches at least one predefined position. Also, in the area of each contact zone (38), the laying arm comprises an actuating projection (101a, 101b) which, in an inactive position, projects from the respective contact zone in the direction of the back-and-forth laying motion and is mounted on the laying arm (27) so as to be movable, in particular pivotable in such a way that in an open position, the actuating projection (101a, 101b) opens said contact zone (38) to allow for the direct contact.

[0007] American patent specification US5535579A discloses a method and an apparatus for precisely adjusting the back tension applied to a stranded conductor after the conductor has been formed and as it is being collected on a bobbin. Unlike a typical strander which uses a single source of power to drive both the twisting portion of the strander as well as the take-up function, the present invention uses a main power source to drive the twisting portion of the strander and it uses a smaller, independently controlled, variable speed, direct current, motor to drive the take up reel. By controlling the reel take up speed, you thereby control the tension that the reel exerts on the conductor being collected thereon. The means for independently controlling the speed of the direct current, variable speed motor that drives the take-up reel is a strain gage which directly measures the tension on the conductor being collected and signals the reel drive motor by way of a controller unit.

[0008] Chinese patent specification CN103662967A discloses an automatic wire arranging device. The existing wire arranging method is prone to notches, wire accumulation and wire jumping. The device comprises a portal frame, a transverse moving platform, a mechanical arm, a lifting mechanism, a horizontal moving mechanism, a dynamic complementing mechanism, an automatic reversing mechanism, a wire winding mechanism, a portal auxiliary frame, a controller and an encoder. Wire arranging is conducted according to a set pitch, in a wire arranging process, the wire arranging device can conduct position complementing control according to actual production conditions, a sheathed line and a designed mechanism structure are arranged in a set angle range.

[0009] US patent specification US4022391A discloses a controlled spooling machine system for layer windings of elongated materials having circular, elliptical, or polygonal cross section, on a rotating spool having a predetermined axial extent, comprising winding speed sensing means sensing the speed of the spool and deriving a winding speed signal representative of speed of rotation of the spool, and means providing a material size signal representative of the width of the material, a guide means guiding the material towards the spool so that the material will define an angle of attitude with respect to a plane transverse to the axis of rotation of the spool, means sensing the attitude angle of the material as it is supplied to the spool, at any instant, and providing an attitude signal, traverse means effecting relative axial traverse movement between the spool and the guide means to effect progressive adjacent winding of the material on the spool and the formation of superimposed layers between the axial limits of the spool, and traverse control means controlling said traverse means and having said winding speed signal, said material size signal and said attitude signal applied thereto and providing a command output signal to said traverse means to command the relative position between said guide means and the instantaneous axial position of the spool such that the material, as it is wound on the spool, is pressed against the next previously applied winding on the spool, by controlling the attitude angle of the material with respect to the spool, as the material is wound on the spool, to reach a predetermined value, and to change the speed of the relative traverse movement in predetermined axial ranges of material placement on the spool, and occurring just before, and after the formation of superimposed windings adjacent the axial ends of the spool such that the attitude angle will tend to become zero as the wire is wound on the spool and approaches an axial end thereof, and, then after formation of a new winding layer, the attitude angle is again controlled to reach said predetermined value.
