Definitions

  • the present invention relates to an apparatus for selectively drawing combed waste by intermittently closing a suction opening used for drawing the waste combed from an endless clearer cloth of a roving frame by an air flow.
  • Sliver in a form of yarn supplied to a roving frame is twisted by passing it through several sets of top rollers and bottom rollers, and there is provided a belt-like endless clearer cloth for cleaning generated waste cotton.
  • the waste cotton adhering to the surface of the endless clearer cloth is scraped off by a comb.
  • the comb is intermittently reciprocated along a moving direction of the endless clearer cloth, and positively scrapes off the waste cotton by a blade at its end during the forward motion. This reciprocation is carried out by a comb reciprocating device including a small electric motor and a cam mechanism.
  • the roving frame includes several sets of endless clearer cloths accommodated in a casing.
  • a sliver 3 in a thread-like form supplied to the roving frame 1 passes between multiple sets of top rollers 4 and bottom rollers 5 in a casing 7.
  • the combed waste suction device 2 is formed of the combed waste intake device 18, the suction opening 24 and a comb reciprocating device 10.
  • the comb reciprocating device 10 includes a small motor 11, a cam mechanism, a rod 13 and a comb reciprocating arm 14. The rotation of the small motor 11 is converted by the cam mechanism 12 and the rod 13 for intermittently reciprocating the comb reciprocating arm 14 in a moving direction of an endless clearer cloth 6.
  • the combed waste intake device 18 includes a dust collecting tube and a shutter (both shown in Figure 2).
  • the combed waste 26 in the dust collecting tube 19 is drawn while the suction opening 24 is open, and is sent through a suction guide 15, an air piping 16 and a collector duct 17 to a dust collector 29 by a blower 27 driven by an electric motor 28. While the suction opening 24 is closed and thus the suction is interrupted, the combed waste 26 gathers at the vicinity of the combed waste intake opening 20 in the dust collecting tube 19.
  • the comb reciprocating device 10 is utilized for the selective drawing, and a dedicated device is not employed.
  • Figure 5 is a perspective view showing a structure in such a manner that the combed waste intake device 18 and the comb reciprocating arm 14 near the combed waste suction device 2 are removed. Only one endless clearer cloth 6 is shown.
  • the shutter which reciprocates together with the comb opens the suction opening only during a period immediately before the completion of the combed waste scraping step and immediately after the start of the rearward movement of the comb, and closes the suction opening during the period other than the above.
  • the opening timings of the respective shutters are sequentially shifted from each other.
