Definitions

  • An improved bobbin assembly is of a type utilized in wire wrapping machines and includes a plurality of bobbins rotatably mounted on a shaft.
  • the shaft has a longitudinal slot so that a keyed washer mounted on the shaft between adjacent bobbins will not rotate.
  • the keyed washers transfer braking force applied at the ends of the plurality of bobbins to each bobbin therein independently of and unaltered by the rotation of adjacent bobbins.
  • a low coefficient of friction for the sliding surfaces of the bobbins and the keyed washers allows the bobbins to operate at a relatively high braking force so that the weight of the bobbins does not significantly effect the operation of the as sembly.
  • This invention relates to a bobbin assembly and, more specifically, to a'bobbin assembly capable of providing equal braking force toeach of thc plurality of bobbins thereon while allowing independent movement thereof.
  • various bobbin assemblies have been provided such as trollable braking friction is applied to each of the bobbins within the assembly.
  • the means utilized therein includes the requirement that the bobbins 'be alternately wound in opposite direetionsso that there is opposite rotation of adjacent bobbins as the wire is being supplied thereby. While generally satisfying the braking problem these prior art" devices have necessitated a more complicated winding of the wire onto the bobbins of the assembly.
  • a preferred embodiment thereof includes an improved bobbin assembly of the type utilized on wire wrapping machines which has a plurality of bobbins rotatably mounted on a shaft between retaining means at the ends of the shaft for applying an axial braking force to each of the bobbins through a plurality of friction washers located between adjacent bobbins for separation thereof.
  • the improvement includes the friction washers being mounted for longitudinal movement along the shaft without rotation thereabout so that the braking force is transferred to each bobbin independently of and unaffected by the rotation of the other bobbins.
  • the sliding contact surfaces between the bobbins and the friction washers have a relatively low coefficient of friction so that a higher braking force may be utilized to reduce the effect on the assembly of the weight of the bobbins in an axial direction during operation of the machine.
  • FIG. 2 is a 'view of the 2 201 FIG. 1,
  • the preferred bobbin assembly '10 prini'arily'includes a shaft 12 with a plurality of bobbins 14 "rotatably mounted thereon.- Each'bobbin 14 ineludes a core 16 about which the wire is initially wound; An opening 18e tending' through the core16 is adaptedfor 'slidably receiving the shaft 12' therethrough. A'pair'of sidwalls 20 ateach end -of thecore l6 retains thewire in alignment with the core 16 asit iseolledted thereon.
  • eachbo'bbin further includes a brake washer 22 concentric with and encircling the opening 18.
  • Each brake washer 22 has a surface having'a low coefficient of friction; such as Teflon, j' the purpose of which will be explained hereinbelow.
  • the'shaft 12 includes a first end 24 having a'retaiiting ring 26 and a second end 28 which is threadedto receive an adjusting nut 30.
  • the retaining ring 26 and the adjusting nut 30 are adapted to retain "the plurality of bobbins 14 therebetween' on the region of the shaft about which they can freely rotatefHowev 'er, to provide the required braking'force, each end 24 and 28 of the shaft 12 includes abiasing means 32.
  • Each biasing means 32 includes a number of elements which encircle the shaft 12 in a side-by-side manner from the end toward the center of thesh'aftf
  • the biasing means 32 includes, in order, a spacing washer 34, a tension disc 36, a limit washer 38 and a spring washer 40.
  • FIG. 1 It can be seen in FIG. 1 how a wide range of braking forces can be generated by the biasing means 32. Because of the spring constant of spring washer 40, initial compression of the biasing means 32 will result in compression of the spring washer 40 to cause it to generate the braking forces having the smallest magnitude. Further compression of the biasing means will cause a collapse of the spring washer until contact is made with the limit washer 38. Since the tension disc 36 is made of a hard resilient material such as rubber, it can be seen that continued compression of the biasing means 32 which will accordingly compress the tension disc 36 so that braking forces of higher magnitude will be produced.
  • each bobbin 14 makes identical sliding, braking contact with a pair of non-rotating keyed washers 44. Since the keyed washers 44 are capable of longitudinal movement along the shaft 12,any force applied at the ends of the shaft of this operation is desirable. Because bobbin assemv blies 6r this type are often used on'ro'tating turntables of a cable winding machine;consideration must be a given to the actual weight of each bobbin as it effects .the.total force appliedto the other bobbins of the assembly Providing the ,lgeyed washers 44 and the brake washers.
  • a-Teflon coating allows a sufficiently ,large rbraking foree, to be applied to the bobbins 14 so that the weight factor is negligible.
  • the low coefficient of sliding frictionr allows a greater force to be applied ,in, the longitudinal direction without actually producing aslid ing friction which would excessively restrict rotation-o f thebobbinr v 7 n g 4 r i I I
  • spring washers 40 for the longitudinal force of lower magnitudes; contact I will be maintained at each end of the plurality of bobbins 14 despite any. tendency therein to shift during rotation of theturntable so that the longitudinal force will be conrtinuously appliedito each bobbin l4.
