Definitions

  • This invention relates to an apparatus for severing a sliver between a can filled with sliver and an empty can at the time of a can changing operation, particularly in an automatic continuous spinning system comprising a plurality of textile machines such as drawing frames.
  • the object of this invention is to provide an automatic apparatus for severing a sliver which extends between the filled up can and the empty can, which is simple in construction and reliable in operation, so that the can changing operation may be effected without any hindrance.
  • the apparatus comprises a pressure lever pivoted to a rigid part such as a coiler plate of a coiler device and adapted to press the sliver against said rigid part, an oscillatable long lever carrying at its free end a sliver nipper consisting of two pivoted arms, means for swinging said longer lever upwardly, and means for closing said two-armed sliver nipper during the upward movement thereof to nip the sliver at a point apart from the point of the sliver nipped by said presser lever, the arrangement being such that the sliver is severed by tension at a point between said two nipping points caused by further upward movement of the nipper carried by the long lever.
  • FIGURE 1 is a side view of an apparatus constructed according to this invention, showing the positions of the parts thereof immediately after the can changing operation;
  • FIGURE 2 is a similar view showing the positions of the parts when one portion of the sliver has been pressed against a fixed part and another portion of the sliver has been caught by an upwardly moving sliver nipper;
  • FIGURE 3 is another similar view showing the positions of the parts when said sliver nipper is moved upwardly further to stretch the sliver immediately before the severing takes place;
  • FIGURE 4 is still another similar View showing the positions of the parts when the sliver has been severed and the sliver end from the coiler has been dropped into the empty can;
  • FIGURE 5 is a front view of the apparatus in the position of FIG. 2;
  • FIGURE 6 is a plan view of the apparatus in the FIG. 2 position
  • FIGURE 7 is an enlarged view showing in detail a sliver nipper
  • FIGURE 8 is a schematic perspective view showing a driving system
  • FIGURE 9 is a diagrammatic view of the apparatus as operated for feeding the sliver from the fullcan to next drawing frame subsequent to the sliver severing.
  • the reference numeral 1 designates calender rollers of a drawing frame
  • 2 a coiler tube
  • 3 is a coiler plate.
  • C and C are sliver cans, one of which is located at the receiving position beneath the said coiler device while being filled with the sliver S from the coiler and the other is located behind said can in the receiving position. It is to be understood that when the can C is filled up the other empty can C is moved forwardly by means of a suitable device (not shown) to take the place of the filled can C, and the continuous sliver extends between the filled up can C and the empty can C.
  • the coiler plate 3 is provided with" apre'sser lever 4 pivoted as at 5 and having at its free .end a hook 6 adapted to be engaged by a presser lever retaining means in the form of a spring 7 on the coiler plate 3.
  • a long oscillatable lever 8 fixed to a rotatable shaft 9 has on its free end a plier-like or two-armed sliver nipper shown in detail in FIG. 7.
  • One arm 10 of said nipper is fixed to the lever 8, while the other arm 11 is pivotably mounted at 12 to said fixed arm, and said two arms are connected by aspring 13 as shown in FIG. 7.
  • the shaft 9 (FIG.
  • the lever 8 has a horizontal stud 14 carrying an antifriction roller 15 adapted to engage with the presser lever 4.
  • a suitable means may be provided to release the engagement of the roller 15 from the lever 4 by shifting the long lever 8 laterally of its length (i.e. upwardly out of the plane of the drawing).
  • the lower end of the pivoted arm 11 of the nipper is acted upon by a projection 16 on the coiler plate 3, whereby the nipper is closed and the sliver is nipped thereby.
  • the sliver will be excessively tensioned, as shown in FIG. 3, and severed at a point between the nip point of the lever 4 and the nip point of the nipper arms 10 and 11 as shown in FIG. 4.
  • an actuating arm 17 fixed to the long lever 8 will co-operate with a rear extension 4' of the lever 4, as shown in FIGS. 3 and 4, so that the lever 4 will be swung downwardly to its initial position, and the severed sliver end will be dropped into the empty can C.
  • the nipper is opened to release the nipped sliver end extending from the filled up can C. Any suitable means may be provided to open the nipper when it returns toward the initial position.
  • the apparatus of this invention may, if desired, be used for feeding the sliver from the filled up can to a feed table or conveyor for the next drawing frame.
  • said lever 8 with the severed sliver end nipped by the closed nipper is rotated further in the clockwise direction (as seen in FIG. 9) passing through the vertical plane for a substantial angle to bring'the nipper over the feed table or conveyor 18 for the next drawing frame (not shown), as shown in FIG. 9, and the nipper is opened by being acted upon by a fixed stop 19 so as to release the sliver end which falls down onto the conveyor 18.
  • An apparatus for severing a sliver when a can changing operation has taken place in a textile machine comprising apresser lever adapted to be pivoted to a rigid part of a coiler device on the textile machine, a long oscillatable lever having a free end, a sliver nipper on said free end comprising two relatively pivotable arms, means coupled to said long lever for swinging said long lever upwardly across the path along which the sliver extends from a full can to an empty can, means on said long lever engaging said presser lever to swing said presser lever so as to nip the sliver between the presser lever and the rigid part, and means for closing said two-armed sliver nipper during the upward movement of the long lever for nipping the sliver at a point spaced from the point at which it is nipped between the presser lever and the rigid part, whereby the sliver is severed by tension between the two nip points during the further upward movement of
  • An apparatus as claimed in claim 2 further comprising a presser lever retaining means adapted to be mounted on said rigid part, and an extension on said long lever engagable with said presser lever onthe opposite side of the pivotal mounting thereof from said retaining means after the sliver has been severed for pivoting said presser lever downwardly and releasing it from. said retaining means.
  • said means for swinging said long lever includes means for continuing the swing of said long lever through a vertical line through the pivot point of said long lever, and sliver nipper opening means positioned adjacent the path of movement of the sliver nipper at said point past the vertical line through the pivot point of said long lever for opening the arms of said sliver nipper, whereby the sliver can be released for feeding to a conveyor or the like for a further textile machine.
