Definitions

  • my invention relates to multi-station winding machines in which a multiplicity of individually operable winding units are provided with a mobile servicing unit or tender whicht travels along a row or group of such stations and automatically performs any needed servicing operation, such as knotting the broken yarn ends from the supply coil and the take-up spool tgether, in order to place a fault-responsively stopped station back to normal operation.
  • Another, more specific object is to prevent, in a multistation winding machine with a mobile tender, the imposition of any control action upon the travelling tender by 3,169,358 Patented Dec. 8, 1964 Mice matic servicing equipment of coil winding machines by avoiding inherently futile knotting attempts and thek like servicing operation; and it is also an object, with respect to mobile-tendermulti-station winding machines, to in ⁇ crease the eiiiciency and working capacity of the tender by eliminating the possibility of having the tender called upon to stop and attempt a knotting operation at an in ⁇ dividual station not properly provided with a yarn-supply coil from-the feeder means of the machine.

  • Pivoted tothe lower end of the main control lever31 is a bell-crank lever 45 to which a reciprocating movement is v imparted by a linking rod 46.
  • This reciprocating motion is transmitted from the oscillating control shaft 8 and the sensing .arm 11 onto a lug at the lower end of the rod 46 and takes place whenever, and as long as, the swing arm 11 is free to participate in the oscillation of the entrainer 9, this being theA case when the tender 13 is not Alocated at:
  • a horizontal tappet 50 (FIG. l) is linked to the latch member 33 and cams an extension 51. If, due to breakage or absence of yarn inthe Winding station, the latch member 33 is turned clockwise about its pivot 33a in the manner described above, the tappet 50 moves toward the right and enters into the travelling range of a switch arm 52 which is pivotally mounted on the housing structure of the tender 13 and is normally in the illustrated upright position.
  • the switchlarm 52 When the tender 13 approaches a winding station in which the tappet 50 has previously shifted to the right, the switchlarm 52 is engaged by the protruding end of the tappet and is turned in one or the other direction depending uponvwhether the tender 13 arrives from the left or right (relating to FIG. 2).
  • the deflecting motion of the switch arm 52 is transmitted by a shaft 52a to the internal mechanisms (not shown) of the tender 13 which cause it to stopv and to operate its yarn-end seeking and knotting devices.
  • a tappet (not shown) protruding out of the tender 13 pushes against the drive control lever 23 and thereby engages the coupling roller 25 with thereverse driving roller 1S for a short interval of time. yDuring that interval the yarn guiding drum 22 is turned in the unwinding direction so that a certain length of yarn is available to be seized by the yarn seeking and knotting devices 13e,
  • the segment105 is connected with the lever 104 by a'biasing spring and has a slot traversed by a stop pinof lever 104.
  • A'lever 106 pivoted at 106e to the arm structure 5 and biased by a spring 10611 for counterclockwise motion, normally rests against the circular periphery of the segment 105.
  • the lever 106 is released and snaps counterclockwise to the illustrated position of PIG. l. Thiscauses a push button 128 to protrude out of the arm structure 5, thus signalling to the attendantv that the yarn package on the take-up spool 21 is completed.
  • control lever- 31 also remains in the illustrated position. f
  • the coil holder 38 fastenedjto the lower end of the y tube 6 carries a peg 67 for receiving the supply coils C.

  • the doffer is actuatedby ya Bowden wire whose active end protrudes from the tender 13.
  • the Bowden wire 66 serves for e turning the peg 67 counterclockwise when itis to receive n a new supply coil that glides downward on a glideway 201.
  • the glideway 201 forms part of the yarn-supply feeder means of the machine and has just enough space to store one spare coil which normally is held in position by a latch lever 203Y rotatable about a pivot 202.
