Definitions

  • PATENTEU JUN29 l97l SHEET 2 [IF 2 APPARATUS FOR AUTOMATICALLY REMOVING IRREGULAR YARN This invention relates to methods of collecting synthetic fiber tow into a container, more practically to instantly discover and take out distinguishably the irregular portion of the running tow which is to be collected into a given container if any and to eject it out of system for preventingit from mixing into the final product or proceeding to the subsequent processes.
  • the irregular portion of a tow designates fuzzing due to broken monofilaments or remarkable reduction in denier. This is very undesirable because of the following unfavorable result; for instance, let continuous filament yarns from several or dozens of spinning positions be grouped into a tow, collected into a containing can, drawn and heat treated. When some yarns from some spinning positions break during the initial spinning operation, the broken ends remaining in the tow proceed to the can.
  • a device for detecting the irregularity of the falling tow is disposed; an arm movable in response to said detecting device is located above a container, ejecting the irregular portion of the tow out of the container for distinguishing, while the tow is being collected into the container.
  • the object of this invention is to instantly detect an irregularity such as broken filaments in an asproduced synthetic fiber tow, to mechanically take out and to discriminate it so that it can be later handled separately, and to prevent it from being present in the subsequent processes.
  • Another object of this invention is to obtain consistently a predetermined quality product in the succeeding drawing operation by removing the irregular portion of the tow.
  • FIG. I is a vertical schematic view of an embodiment of this invention.
  • FIG. 2 is a plan view as seen along the line A-A of FIG. 1.
  • FIG. 3 is a perspective view of another embodiment.
  • FIG. 4 is a schematic view of a photoelectric detecting device shown in FIG. 3.
  • tow is fed by gravity in the falling state into a container 2.
  • Said container is given a proper motion to lead the tow uniformly.
  • a photoelectric detecting device is disposed apart from both sides of the tow above said container, said device consisting of light projecting part 3 and light receiving part 4 facing each other to detect the irregularity of tow I, if any.
  • motor 6 is fixed to frame 7 above container 2, said motor being connected with arm 5. Arm is at a standstill around a solid line in the normal condition as shown in FIG.
  • a buzzer may be rung and an alarm lamp may be provided for detecting the irregular portion of the tow.
  • the length of the arm is required to cover the whole opening of the container.
  • FIG. 3 Another embodiment of this invention is described with reference to FIG. 3.
  • emphasis is specially laid on the uniform collection of tow 1 into container 2.
  • Tow l is fed from above and received into container 2. If tows descending position is kept constant, and the tow is received into container 2 at a given location, tow 1 accumulates in the same place in said container and the coefficient of utility of container 2 lowers.
  • FIG. 3 to avoid this fault, it is designed to move container 2 back and forth, left and right and to receive tow l uniformly on the base of the container.
  • Container 2 is disposed on endless belt 8 which makes a reciprocating motion with-a predetermined traverse length and in the direction. Endless belt 8 is mounted on another endless'belt 9, the frame of the former being fixed with the upper part of the latter.
  • the latter makes a reciprocating motion having a specified traverse length also.
  • the directions of the two, and N make right angles with each other.
  • the traverse length of endless belt 8 is slightly shorter than the width of container 2 measured by the direction of the reciprocating motion.
  • the reciprocating motions of endless belts 8 and 9 are controlled as follows: In the case of endless belt 8, it is desirable to have as high a reciprocating speed as the operation will allow, but it is essential to set the reciprocat ing speed to the falling speed of tow 1; that is, in order to arrange the falling tow I on the base of container 2 in order, it is desired to feed tow I in exact quantities. Endless belt 9 moves very gradually. Its speed is determined as follows:
  • endless belt 9 moves very slowly, and its speed is equivalent to that of one stroke of endless belt 8 placing two lines of tow 1.
  • FIG. 4 is a flowsheet which shows one embodiment of the present invention in collecting a tow into a container by laying together the as-produced continuous filaments from some spinning positions. Filaments l extruded from a plurality of spinnerets are passed through guide roller 9, gathered into a tow 1, led at a constant rate of speed with tension roller as sembly 9, and stored into container 2 with a pair of gear nip reels 9". Below the spinnerets 15 are yarn receiving device 15 disposed.
  • tow makes proper motion when a tow falls from a predetermined position, thus collecting the tow into the container uniformly.
  • tow may be moved in circular motion, or back and forth, left and right, and then collected uniformly into container, while the container is at a standstill.
  • the efiect of the present invention may be clearly understood if a case without the inventive device is considered.
  • the broken filaments are not drawn, are heavier in denier, and dyes heavier shades, if dyed.
  • the commercial value of the products is much decreased.
  • Such fault can be easily distinguished, and surely removed by this invention.
  • the irregular portion of the tow is outside the container, the removal operation of said portion is very simple.
  • the process in the present invention readily prevents the irregular portion of tow from remaining in the products and proceeding to the subsequent processes by automatically and accurately ejecting said irregularities outside a container during the tow storage in the container.
  • Apparatus for automatically removing irregular yarn including container means for receiving yarn;
  • motor means disposed between said container means and said photoelectric detection means and including an arm movable through a path intersecting the path of said yarn between said supply and said container means;
  • control means responsive to said photoelectric detection means to actuate said motor means when irregular yarn is sensed to move said arm through said intersecting path whereby irregular yarn is automatically prevented from being received by said container means.
  • said container means includes a container disposed on a first conveyor having a reciprocating motion of predetermined traverse length, a frame supporting said conveyor, and a second conveyor disposed transversely of said first conveyor and attached to said frame, said second conveyor having a reciprocating motion of predetermined traverse length.
  • said supply includes a plurality of spinnerets, and further comprising a yarn receiving device disposed below each of said spinnerets and guide means receiving said yarn from said devices and forming a fiber tow, said photoelectric detection means being aligned with said yarn receiving devices to detect the accumulation of irregular yarn thereon, and said motor means being disposed between said guide means and said container with said arm movable to move said fiber tow to a position outside of said container when irregular yarns are detected.
