Definitions

  • the present invention relates to a movement setting device for a detaching roller of a comber, and more particularly, to a movement setting device for a detaching roller of an independent comber that drives the detaching roller with a motor that differs from a motor that drives a combing cylinder, as known e.g. from WO 2007/093120 .
  • a comber includes a nipper and a combing cylinder.
  • a lap is fed to the nipper, which holds the lap at a rear position to which the nipper moves.
  • the combing cylinder combs a front end of the lap, which is held by the nipper. This removes short fibers from the lap, which becomes fleece.
  • the nipper moves forward to move the fleece toward the detaching roller.
  • Rotation of the detaching roller is reversed in correspondence with the forward movement of the nipper to move a fleece that was received previously (front fleece) toward the rear. This overlaps a front end portion of the preceding fleece with a rear end portion of the newly combed fleece (trailing fleece).
  • the detaching roller is rotated forward.
  • the detaching roller receives the fleece from the nipper and joins the preceding fleece with the trailing fleece.
  • a top comb comb a rear end of the trailing fleece.
  • the movement of the detaching roller in the comber greatly affects the sliver quality (evenness) and machine load in a cycle that performs the cutting of fiber fleece, combing, and piecing (joining).
  • a drive shaft (cylinder shaft) of the combing cylinder is transmitted by a mechanical mechanism, such as a cam or crank, to the detaching roller in accordance with a movement curve of the detaching roller.
  • piecing point adjustment that is in accordance with the spinning conditions is mechanically performed.
  • the mechanical structure imposes limits on the movement curve (output curve).
  • a comber that drives the detaching roller with an independent and dedicated motor instead of the cylinder shaft has been proposed (refer to, for example, Japanese Laid-Open Patent Publication No. 8-260255 ).
  • the publication describes a comber that drives a detaching roller (detaching cylinder), a cylinder shaft (circular comb shaft), and a nipper shaft with different driving devices.
  • the driving device of the detaching is a servomotor and especially advantageous in which an adjustment signal controls an energy supplying device of the servomotor to change the position of a starting point A of a detaching movement, a detaching speed (t), a detaching length (a), or a joining interval (I).
  • the starting point A and the like are shown in Fig. 4 , which illustrates the motion process for a single point on the circumference of the detaching roller during a single rotation of the cylinder shaft.
