Definitions

  • the present invention relates to a spooling device, for use in unwinding wire from a bobbin, which employs a compensated inertia arrangement.
  • the start of the wire for unwinding is effected in the pick-up manner" in a free or individually driven manner.
  • This spooling method by unwinding nevertheless has numerous drawbacks, such as the twisting of the wire and the need to create tension.
  • each bobbin being driven by a controlled variable speed motor.
  • An object of the invention is to bring about a rational and economic solution by using an unwinding terminal which may comprise a plurality of stations, provided with a common simple drive and suitable braking means.
  • a spooling device for use in unwinding wire from a bobbin employing an inertia arrangement, including a bobbin, a hub on which the bobbin is mounted in free rotation, a support shaft over which the hub is capable of sliding, the axis of the support shaft being inclined by an adjustable angle a with respect to the horizontal, means for rotatably driving the support shaft, a friction disc integral With the support shaft, a friction packing between one face of the hub and the friction disc, the face of the hub bearing by means of the packing against the friction disc under the action of a force F which is a function, on the onehand of the inherent weight of the hub and bobbin and, on the otherhand of the value of the angle of inclination a, a cylindrical bearing at one of the ends of the hub, a brake band, an oscillating lever, and a resilient return member for counteracting the oscillating lever, the oscillating lever being linked to thebrake band, the brake band being arranged over the cylindrical
  • a terminal having a frame which does not occupy any more space than a normal frame and which enables the advantages of spooling by unwinding to be preserved, in particular the characteristic of an absence of twisting of the wire.
  • control of the speed does not necessitate any fine adjustment and does not require any follow up.
  • FIG. 1 is a view in longitudinal section of a spool device for wire employing a compensated inertia arrangement
  • FIG. 2 is a view in elevation ofa wire spooling assembly comprising a plurality of bobbins.
  • the wire spool device for unwinding wire employing compensated inertia shown in FIGS. 1 and 2, comprises a frame 1 on which a bearing 3 provided with ball bearings 4, 4a is fixed by means of screws 2, the said bearings being separated by a cross member 5 and held by resilient rings 6, 6a arranged in grooves.
  • a shaft 7 is mounted to rotate within the bearing 3, the axis xx, of the shaft being capable of being inclined by an angle with respect to the horizontal axis yy, by means of the frame 1 which is adjustable in position.
  • a hub 9 is mounted for free rotation on the shaft 7 by means of needle or roller bearings 8, 8a, a bobbin l0 being engaged on the shaft and held fixed against a shoulder Il of the hub by a cap 12 screwed on to a threaded end of the hub.
  • the hub 9 has, at its other end, a flange 13 which bears, by means of a friction packing 14, against a friction disc 15 keyed at 16 to the shaft 7.
  • the hub 9 and the external housing 17 of the roller bearings 8, 8a are capable of sliding axially and freely with respect to the interior housing I8 and to the shaft 7 to compensate the wear of the friction packing 14, thereby to obtain effective contact between the flange 13 and the friction packing.
  • the flange 13 of the hub 9 is extended to provide a cylindrical bearing surface 19 on which a brake band 20 is arranged.
  • the brake band 20 is wound over a pulley 21 mounted on an oscillating lever 22 (FIG. 2) provided on one of its ends with a wheel 23 for guiding the wire 24 upon its exit from the bobbin.
  • the oscillating lever 22 is attached to a spring 25 fixed at 26 to a frame member 27, the spring 25 exerting a force on the oscillating lever opposite to the traction strain of the wire 24, in such a manner that the oscillating lever exerts a torque C, over the braking band 20.
  • the spring 25 acts on the oscillating lever 22, this latter rotates about axis 0 in the direction of arrow F2 and since the lever arm enters point 0 and point 33, a traction is exerted on the band 20 and a braking torque C1 is applied to the pulley 19.
  • a grooved pulley 28 which enables the shaft 7 to be rotationally driven and which is linked by a belt 29 to a driving pulley 30 which is driven by means of a belt transmission 31 by a brake motor 32.
  • the number of bobbin stations or supports on the frame 1 is a function of the size and weight of the bobbins, it being understood that it is advantageous to arrange the largest possible number of stations per frame, so as to only use a single drive motor.
  • the spooling device operates in the following manner.
  • the motor 32 is started thereby ensuring the driving of the pulley 28 and the shaft 7 by the belt transmission 31 and the belt 29.
  • the hub 9 is locked by the action of the brake band 20 on the surface of the bearing 19, which is subjected to a braking torque C, exerted on the oscillating lever 22 by the spring 25. In this position, the friction disc l5 slides with respect to the hub 9 and to the bobbin l0 which is not driven.
  • the drive torque C2 of the bobbin can be adjusted by modifying the angle a, F being the force of pressure exerted by the hub 9 against the friction disc l5, as shown on the diagram of forces of FIG. l.
  • the modification of the angle a may be readily obtained through varying the inclination of frame l in a manner well known in the art, such as, by suitable screws and nuts or cams (not shown).
  • frame 1 mayinclude a plate portion 33 which is hingedly connected at 34 to the frame member 27. The latter may have threaded therethrough an adjusting bolt 35, the upper end of which contacts the lower surface of frame 1 so as to vary the angle of inclination thereof in response to adjustment of bolt 35 relative to frame member 27.
  • F is a function of the weight P and of the value of the angle a in which P is equal to the weight of the hub 9 and bobbin 10.
  • the braking torque Cl exerted by the band on the hub 9 must be greater than the torque C2 transmitted by the friction disc 15.
  • the value of the torque Cl can be regulated by means of the spring 25.
  • the pulley 28 For unwinding the wire at a constant speed, the pulley 28 should be driven at a speed slightly greater than the speed of the bobbin at the end of spooling operation. At the beginning of the spooling operation, the speed of the bobbin is slower and the slipping greater than at the end of the operation.
  • the wire spooling device according to the invention can also be applied to a bobbin supported between points.
  • a spooling device for use in unwinding wire from a bobbin employing a compensated inertia arrangement including a bobbin, a rotatable hub on which the bobbin is mounted, a support shaft having the hub slidingly and rotatably supported thereon, the axis of the support shaft being inclined by an adjustable angle a with respect to the horizontal, means for rotatably driving the support shaft, a friction disc integral with the support shaft, a friction packing between an end surface of the hub and the friction disc, said end surface of the hub bearing through the intermediary of the packing against the friction disc under the action of a force F which is a function of the inherent weight of the hub and bobbin and of the value of the angle of inclination a, a cylindrical bearing surface formed at one of the ends of the hub, a brake band, an oscillating lever and a resilient return member for counteracting the oscillating lever, said oscillating lever being linked to the brake band, the brake band being arranged over the cylindrical bearing surface
  • a spooling device including bearing means having internal and external casings mounting the hub on its support and drive shaft, the external casings being freely slidable with the hub with respect to the internal casings and the shaft.
  • a spooling device including a frame having an adjustable portion, a roller bearing mounting the bobbin support sahft on said adjustable frame portion, and means for varying the inclination of said frame portion, so as to concurrently vary the value of the angle a which the axis of the bobbin support shaft makes with the horizontal.
  • a spooling device including a pulley, on which the brake band of the hub is wound, carried on the central part of the oscillating lever and a wheel at one of the ends of the oscillating lever over which the wire passes upon its exit from the bobbin, the oscillating lever being subjected at its other end to the action of the resilient return member which counteracts the tension on the wire.
