Definitions

  • the present invention relates to the textile industry, in particular pin benches for long fibers and short fibers, in particular the driving of the bobbins of such pin benches, and relates to a drive device intended for this purpose. .
  • the rotary drive of the spindle bench bobbins is generally carried out by means of a nose disposed at the base of the spindle and cooperating with a notch formed in the base of the bobbin.
  • the nose which cooperates with said notch thus drives the bobbin.
  • to carry out such a drive it is necessary for the operator to bring the notch of the bobbin in cooperation with the nose of the spindle.
  • the present invention aims to overcome these drawbacks.
  • a device for driving the bobbin of a bench with spindles for long and short fibers the spindle of which has at its free upper end an elastically deformable drive means cooperating by shape with a corresponding arrangement of the inner upper part of the bobbin, characterized in that the elastically deformable drive means is independent of the spindle, is fixed to the upper end of the latter and is constituted by a tulip-shaped lamellar spring, said lamellas being arranged at regular intervals around the periphery of the upper end of the spindle and extending, by their upper part curved in a concentric crown, beyond the diameter of the spindle, the elastically deformable drive means thus allowing a friction drive in the event that the lamellae are not positioned opposite the fittings corresponding to the inner top of the bobbin.
  • the device for driving the bobbin of a bench with spindles for long and short fibers is provided with a spindle 1 having at its free upper end an elastically deformable drive means 2 cooperating by shape with a corresponding arrangement of the upper inner part of the bobbin.
  • the elastically deformable drive means 2 is advantageously constituted by a leaf spring 3 in the form of a tulip, said blades 3 being arranged at regular intervals around the periphery of the upper end of the spindle 1 and extending through their part. upper bent in a concentric crown, beyond the diameter of the spindle 1.
  • the arrangement of the upper internal part of the bobbin preferably consists of notches of shape corresponding to that of the lamellae 3 and extending at corresponding regular intervals, or alternatively of grooves extending over the entire internal part of the bobbin.
  • each fin of the spindle bench is provided near its axis with a flexible stop intended to cooperate with the upper part of the bobbin in order to promote a total nesting of the latter on the spindle 1.
  • the drive device Due to a large number of lamellae cooperating with a corresponding number of notches or splines, the drive device according to the invention allows the bobbin to be pushed entirely onto pin 1 of a pin bench whatever or the angular position of said bobbin relative to said spindle 1.
  • the device according to the invention does not produce any axial thrust on said bobbin, preventing the latter from tending to rise up.
  • the lamellae of the spring act simultaneously in order to cancel any radial play of the bobbin on the spindle 1, thus avoiding any possibility of vibration.
