Definitions

  • This invention relates to a textile winding apparatus and relates more particularly to an automatic .doffing apparatus for a yarn winding machine.
  • a further object of this invention is the provision, on a yarn winding machine to which yarn is supplied continuously at a constant rate, of an automatic dofiing apparatus which will prevent the wastage of yarn during the doffing period.
  • Another object of this invention is to provide a simple and eificient automatic dotting apparatus which utilizes gravitational force for the movement of the parts during the dofling operation.
  • the apparatus comprises a pair of articulated arms pivotally mounted side by side on a common horizontal axis.
  • a mandrel for rotatably mounting a yarn package support, such as a cardboard yarn tube.
  • one arm is supported, by a movable dog, in an operative position in which its yarn tube bears against a rotating drive roll, which roll frictionally engages the yarn tube to rotate the latter and wind yarn thereon.
  • the second arm is in'an inoperative position, supported above the first arm by any suitable means, such as a projecting pin, mounted on said first arm.
  • the dog supporting said arm is moved out of the path of the first arm and into the path of the second arm. Accordingly, the first arm drops and swings on its horizontal pivot to an inoperative position where its wound yarn tube is out of engagement with the drive roll, while the second arm moves downward until said second arm engages the dog.
  • the dog now supports said second arm in an operative position where the empty yarn tube of said second arm bears against the drive roll. As a result of these movements a portion of the yarn which trails from the wound yarn tube is nipped between the empty yarn tube and the drive roll.
  • the first arm by engaging a switch which controls a piston connected to a curved cutter or knife, causes said knife to sever the trailing portion of yarn and bring the cut end of yarn into close proximity to the empty yarn tube.
  • a stream of air is directed between .the curved knife and the empty rotating yarn tube to cause the yarn to engage said tube and to maintain the yarn in contact with said tube to start the winding of the yarn on said tube.
  • the movement of the dog may be controlled in any suitable manner.
  • it may be controlled by a timer, which is set to move the dog after a yarn tube has been driven by the drive roll for the period of time necessary to wind the desired amount of yarn thereon.
  • the speed of the drive roll is substantially constant so that the amount of yarn wound on the yarn tube is directly proportional to the time of winding.
  • the dog may be controlled by a suitable counter which acts to move the dog when the drive roll has made the desired number of revolutions.
