Definitions

  • This invention relates to yarn clearing and spooling arrangements and, more particularly, to a novel and improved yarn cutting and clamping mechanism for such arrangements.
  • the cutting and clamping operation is only triggered electromagnetically, with the actual cutting and clamping being effected purely mechanically.
  • the cutting and clamping device is actuated due to the initial tension of a spring and, during the subsequent re-setting, this spring is re-tensioned by a mechanical movement. While this device is satisfactory in operation, it has certain disadvantages which detract somewhat from its commercial prac' ticability.
  • An object of the present invention is to provide in a yam-clearing arrangement, yarn cutting and clamping mechanism including yarn cutting means, yarn clamping means, means selectively operable to actuate the cutting means to cut yarn, and means operatively associated with the cutting means and the clamping means and operable, simultaneously responsive to actuation of the cutting means, to actuate the clamping means.
  • Another object of the invention is to provide, in yarnclearing arrangements or the like, yarn cutting and clamp- 3,322,913 Patented May 30, 1967 ing mechanisms including electromagnetic means for operating a yarn cutting and clamping means in such a manner that the yarn first is cut by the cutting means and then is clamped by the clamping means for as long as the electromagnetic operating means remains energized.
  • a further object of the invention is to provide, in a yarn-clearing arrangement or the like, yarn cutting and clamping mechanism including yarn cutting means and yarn clamping means, electromagnetic means selectively operable to actuate the cutting means to cut yarn, and means operatively associated with the cutting means and the clamping means and operable, simultaneously responsive to actuation of the cutting means, to actuate the clamping means.
  • Yet another object of the invention is to provide, in a yarn-clamping arrangement or the like, yarn cutting and clamping mechanism in which a cutting means is actuated by an electromagnetic operating means which then exerts the force for maintaining the clamping mechanism actuated.
  • Still a further object of the invention is to provide, in a yarn-clearing arrangement or the like, yarn cutting and clamping mechanism including yarn cutting means and yarn clamping means, and in which the duration of the clamping may be selected as desired.
  • Still another object of the invention is to provide, in a yarn-clearing arrangement or the like, yarn cutting and clamping mechanism including electromagnetic means for actuating the yarn cutting means and for maintaining the yarn clam-ping means actuated to clamp the severed yarn until a known gripping means has gripped the severed yarn.
  • Still a further object of the invention is to provide, in a yarn-clearing arrangement or the like, yarn cutting and clamping mechanism including yarn cutting means and yarn clamping means, and electromagnetically energized means for actuating the cutting means and for maintaining the clamping means actuated to clamp the severed yarn at least until the yarn has become steadied following the sudden interruption of its movement.
  • FIG. 1 is a partial sectional view illustrating the yarn cutting and clamping mechanism of the invention as incorporated in a yarn-clearing arrangement, the cutting and clamping mechanism being shown in the inactive or rest position;
  • FIG. 2 is a view similar to FIG. 1, but illustrating the cutting and clamping mechanism immediately after actuation thereof.
  • the yarn 1 traverses the active part of a known or conventional yarn cleaner.
  • the yarn travels upwardly through a slot 2 which extends through both of the housing parts 3 and 4 and also through the cutting and clamping zone disposed therebetween.
  • the cutting and clamping zone contains the yarn cutting and clamping mechanism of the invention.
  • a cutting knife 5 and a clamping slide 6 on one side of the slot 2 there are disposed a cutting knife 5 and a clamping slide 6, the cutting knife 5 being provided with a bevelled yarn cutting edge.
  • a stationary counter-support or block 7 On the other side of the slot 2 there is disposed a stationary counter-support or block 7 having a pressure surface 8 facing the slot 2 and engageable by the ends of the cutting knife 5 and the clamping slide 6.
  • Knife 5 and slide 6 are mounted in housing parts 3 and 4 for easy lateral displacement both individually and conjointly. Relative displacement of knife 5 and slide 6 is limited by a compression spring 9 which is disposed in superposed recesses 10 and 11, one in knife and the other in slide 6. The arrangement is such that, in the rest position illustrated in FIG. 1, the cutting edge of knife 5 'or aperture in slide 6. When displacement forces are exerted on slide 6, one or the other of the arms of spring 12 is tensioned. The arrangement is such that, in the rest or inactive position shown in FIG. 1, slide 6 and knife 5 assume the position illustrated therein, under the influence of the springs 9 and 12.
  • An armature 14 is operatively associated with the outer end of knife 5.
  • Armature 14 is swingably mounted on a pivot 16 on housing part 3, and is within the magnetic field of an electromagnet 15.
  • electromagnet 15 When electromagnet 15 is energized, it attracts armature 14 and thus moves the same to the left.
  • the electromagnet 15 is energized responsive to a cutting pulse, and armature 14 pushes knife 5 to the left so that the cutting edge of knife 5 severs yarn 1 against pressure surface 8.
  • clamping slide 6 is moved to the clamping position by means of the pressure of compression spring 9 so that its clamping surface presses the yarn 1 or, respectively, the part thereof running toward the cutting station, against pressure surface 8.
  • the interval of time between the impingement of armature 14 against knife 5, or, respectively, the cutting and a clamping operation under the action of cutting pulse until the dropping of armature 14 resulting in cancellation of the clamping action can advantageously be determined by opening of an external contact 18 included in the energized circuit of electromagnet 15. It is also advantageous if, after the decay of the cutting pulse, electromagnet 15 releases armature 14 only after a given time delay, to let clamping slide 6 return to its rest position.
  • the release time of armature14 can be set in a manner known to those skilled in the art.
  • Operation of the cutting and clamping means is effected, in the usual manner, by a pulse or signal from the yarnclearing arrangement which, through the illustrated circuit, energizes the electromagnet 15. Such energization may be momentary or may be maintained for a predetermined period. 7
