Definitions

  • ABSTRACT A registration means for the alignment of a piecing apparatus with yarn processing stations of a textile machine requiring yarn repair, comprising control cam means which controls the registration engagement of the piecing apparatus with the textile machine by the registration means through provision of a counterbias or holding function, a registration camming means for bringing the apparatus into registration with stations requiring yarn repair and maintaining it there by engagement with the machine in a camming action, and resilient biasing and joining means for joining the control means to the camming means and providing a bias to the camming means for its resilient engagement with the textile machine.
  • Such engagement may be made with camming notches or slots in a guide rail of the machine in register with the stations, or any other suitable way such as with camming projections from the machine.
  • the camming means may be a cam follower lever arm with a roller for engagement with the machine, and in another a plunger rod for entry into registration slots in the machine, such as in a guide rail.
  • the yarn processing station comprises a yarn delivery station from which yarn issues and a yarn take-up station at which the issued yam is collected as a package.
  • the yarn delivery and take-up stations are in line with one another thus requiring a single positioning of the carriage adjacent thereto to carry out the yarn repair activities; in yet others the two stations are not in line, but are somewhat offset longitudinally on the frame, thus requiring two sequential alignments of the carriage in order that all of the servicing functions of the device may be successfully carried out in repairing the yarn;
  • difficulties are often encountered due to the high inertia which must be overcome in stopping and positioning the carriage and its servicing mechanisms.
  • a carriage braking and registering mechanism comprising a guide rail running longitudinal the spinning frame having registration notches cut into the top edge of the rail and a flange projecting outwardly therefrom, a position registration switch mounted on the carriage having an outwardly projecting biased roller to cooperate with the guide rail and the notches, the notches being correlated with the frames servicing stations and the roller running along and in contact with the outward surface of the projecting flange of the frame guide rail.
  • a registration lock mechanism which comprises a downwardly depending tapered pin normally positioned on the carriage above the guide rail notched flange, by means of a horizontally extending lever arm pivotally connected at its midpoint to the armature of a normally deactivated solenoid.
  • An object of this invention is to provide a piecing apparatus carriage registration means for precise alignment with a yarn processing station of a textile machine requiring servicing thereat which is durable and of simple construction.
  • Another object of this invention is to provide an aforesaid registration means which maintains precise alignments despite wear occasioned by long-termed andlor continuous usage and despite heavy textile machine vibration.
  • Yet another object of the invention is to provide embodiments which will precisely align the carriage at each of a plurality of yarn processing stations off-set longitudinal one another in the processing of a single strand of yarn.
  • a piecing apparatus registration means comprising a control cam means for controlling the registration activities of the registration means which imparts a plurality of discrete counterbiases or holdings against the bias of the below described resilient biasing and joining means, registration camming means for cooperation with registration camming surfaces on the textile machine which are correlated with yarn processing stations thereof at which ends down conditions may occur to bring the piecing apparatus carriage into registration with such stations for yarn piecing activities thereat, and for bringing the piecing apparatus into such registration and resiliently and positively maintaining it in such registration during yarn repair activities, and resilient biasing and joining means for joining said control cam means with said registration camming means for control of the latter thereby and for biasing said registration camming means against the counterbias of said control cam means for resiliently biasing said camming means into registration with an appropriate station requiring servicing and for maintaining it in registration during yarn repair activities, and further for biasing said camming means out of contact with
