Definitions

  • the invention relates to a doubling machine which provisionally joins a plurality of threads together to feed it to a wind-up package in which a doubled yarn is wound up by moving the yarn thread traversely.
  • a metallic roller 51 is generally provided which has a groove to introduce the yarn thread 54 to the drum. Since an inner wall of its groove is plated by chrominum (Cr), a static electricity is induced due to friction between the yarn thread 54 and the metallic roller 51 during the process in which the yarn thread 54 of the long-and short-fibrous threads 52a, 52b united together at a collecting unit 53 runs slidingly through the metallic roller 51.
  • the static electricity tends to attract the the long-fibrous thread 52a to a smooth outer surface of the metallic roller 51 rather than the short-fibrous thread 52b. This causes to temporarily stick the long-fibrous thread 52a to the outer surface of the metallic roller 51 so as to slack the thread 52a at a releasing side of the metallic roller 51.
  • the present invention is made after delving deeper into the behaviour of the yarn thread running through the roller so as to eliminate the above drawbacks.
  • the threads With the rotational movement of the pulley, the threads are provisionally twisted lightly in which the yarn thread encounters the protuberances, thus changes the twisting degree substantially depending on the portion of the yarn thread. Particularly when the threads are made of several thread segments, these thread segments are entangled each other when the yarn thread encounters the protuberances, and thereby twisting the threads all the more tightly. This prevents the provisionally twisted yarn thread from straying apart when the yarn thread passes the pulley, and thus prevents the yarn thread from being wound up with the yarn thread strayed apart. This apparently leads to smoothly winding up the yarn thread at high speed.
  • the threads With the rotational movement of the pulley, the threads are provisionally twisted lightly in which the yarn thread encounters the cut-out portions, thus changes the twisting degree substantially depending on the portion of the yarn thread. Particularly when the threads are made of several thread segments, these thread segments are entangled each other when the yarn thread encounters the cut-out portions, and thereby twisting the threads all the more tightly as a whole. This prevents the provisionally twisted yarn thread from straying apart when the yarn thread passes the pulley, and thus prevents the yarn thread from being wound up by the wind-up package with the yarn thread strayed apart. This apparently renders the winding up operation smooth at high speed.
  • the angle-adjustable member is an assemble of a plurality of angular plates which inclines the pulley obliquely against the thread-supply path (Tp, Tq), while at the same time, adjusting the tension of the yarn thread within the thread-supply path.
  • the pulley is made of a wear-resistant ceramic material such as alumina, zirconia and titania.
  • the pulley may be made of semi-ceramic material such as, for example, boronic titanium.
  • the ceramic material With the use of the ceramic material, it is possible to reduce the friction between the yarn thread and the inner walls of the pulley along which the yarn thread slides. This makes it possible to reduce the static electricity between the yarn thread and the inner walls of the pulley, thus positively tangles the threads by provisionally twisting them.
  • the ceramic material By using the ceramic material to the axis, it is possible to put a durable oiless bearing into a practical use.
  • threads 2a, 2b are emanated from respective thread-supply path packages 1a, 1b by way of tension pulleys 3a, 3b.
  • the threads 2a, 2b which run through the respective tension pulleys 3a, 3b are united together at a guide roller 4 to form a yarn thread 5.
  • the yarn thread 5 is introduced to a drum 7 by way of a support guide 10.
  • a honing or blast (shot peening) treatment is provided which is a step prior to an aventurine plating.
  • the outer surface 7a of the drum 7 has a closed-ended traverse groove 8, and adapted to rotate by a drive unit (not shown).
  • a wind-up package 9 is pressed in the manner to circumscribe with the drum 7 by means of a cradle arm (not shown).
  • the wind-up package 9 is designed to rotate in combination with the rotational movement of the drum 7.
  • An outer periphery of the pulley 11 has a groove 12 which is generally V-shaped in cross section as shown in Figure 2.
  • the wheel 11 has flanges 15a, 15b whose inner walls are continuous from inner walls of the groove 12 by way of stepped portions 14a, 14b which are provided between an outer periphery 13a of the inner wall of the flange 15a and a cam-like outer periphery 13b of the inner wall of the flange 15b.
  • the flange 15a is diametrically greater than the stepped portion 14a
  • the flange 15b is diametrically greater than the flange 15a.
  • both the cam-like outer peripheries 13a, 13b of the inner walls of the flanges 15a, 15b are circular.
  • both the outer peripheries 13a, 13b of the inner walls of the flanges 15a, 15b are eccentric with the rotational axis lla of the pulley 11 as shown in Figures 3a and 3c.
  • the eccentric direction of the center 16a of the cam-like outer periphery 13a is different from that of the center 16b of the cam-like outer periphery 13b.
  • the eccentric direction of the center 16a is in 150-degree offset relationship with that of the center 16b when defined in terms of the rotational angle as shown in Figure 3b. That is to say, the center 16a is out of point symmetry from the the center 16b by 30 degrees.
  • the eccentricities M of the centers 16a, 16b from the rotational axis 11a are the same in somuch as the cam-like outer peripheries 13a, 13b are within outer limits of the flanges 15a, 15b.
  • the steel axis 11A of the pulley 11 is not perpendicular to a thread-supply path (Tq) which is formed by the yarn thread 5 supplied from the guide roller 4 as also shown in Figure 4.
  • the steel axis 11A is instead oblique across the thread-supply path (Tq) so that the yarn thread 5 invariably slides on the cam-like outer periphery 13a of the flange 15a or the inner wall 12x of the groove 12 before running through the bottom 12a of the groove 12.
  • the steel axis 11A of the wheel 11 is not perpendicular to a thread-supply path (Tp) which is formed by the yarn thread 5 supplied from the wheel 11 to the drum 7.
  • the steel axis 11A is instead oblique across the thread-supply path (Tp) so that the yarn thread 5 invariably slides on the cam-like outer periphery 13b of the flange 15b or the inner wall 12y of the groove 12 before running out of the pulley 11.
  • the yarn thread 5 run out of the pulley 11 enters the traverse groove 8 of the drum 7, and axially moves in the direction of a double-headed arrow R within certain angular limits.
  • a detection unit (not shown) is provided to detect whether or not the threads 2a, 2b are accidentally disconnected.
  • a yarn cutter is provided although it is not shown.
  • the running of the yarn thread 5 facilitates the smooth rotation of the pulley 11 since the inner walls 12x, 12y of the V-shaped groove 12 are roughened because the pulley 11 is made of the ceramic material.
  • Facilitating the smooth rotation of the pulley 11 leads to yielding a minimum friction between the yarn thread 5 and the pulley 11 so as to reduce the occurrence of the static electricity.
  • With the reduced static electricity and provisional twist of the yarn threads 2a, 2b it is possible to prevent one of the theads 2a, 2b from sticking to the bottom 12a of the groove 12, thus avoiding the other thread from being overfed at the feeding side of the pulley 11.
  • the twisting degree of the yarn thread 5 changes depending on the position in which the yarn thread 5 slides on the inner walls 12x, 12y of the groove 12 so as to induce variations in the twisting intensity. This enables to provisionally twisting the the yarn thread 5 effectively so as to strongly unite the threads 2a, 2b together.
  • the pulley 11 may be made from zirconia or titania (TiO 2 ) instead of alumina (Al 2 O 3 ), otherwise the wheel 11 may be made by baking wear-resistant ceramic powder of titanic boron (TiB 2 ).
  • eccentricity M of one cam-like outer periphery of the flange may be different from that of the other cam-like outer periphery of the flange insomuch as the wheel can slide the yarn thread on it without let and hindrance.
  • the eccentric direction of the center 16a is may be within (180 A 10)-degree offset relationship with that of the center 16b when defined in terms of the rotational angle, in which the provisional twisting timing when running into the pulley is substantially opposite to the provisional twisting timing when running out of the pulley.
  • the centers 16a, 16b of the stepped portions 14a, 14b may be in concentric relationship with the center of the bottom 12a of the groove 12 with the flanges 15a, 15b having different diameter (D 1 , D 2 ) as shown in Figure 2a.
  • the flanges 15a, 15b provided diametrically different, diameters of the stepped portions 14a, 14b become different so that one of the opposed inner walls 12, 12 is dimensionally greater than the other.
  • Figure 5 shows a modification form of the first embodiment of the invention in which two angular plates 21, 21 are connected each other as the angle-adjustable member 20.
  • the threads 2a, 2b may be adapted to run through two guide rollers after running through the tension pulleys 3a, 3b, and the threads 2a, 2b may be united together at one of two guide rollers.
  • the guide rollers may be made of the ceramic material.
  • Figure 6 shows a second embodiment of the invention in which a general pulley 110 is used which has a groove 111 V-shaped in cross section.
  • Inner walls 112 of the groove 111 have a plurality of protuberances 113.
  • the yarn thread encounters the protuberances 113 at the side of feeding it to the pulley 110 and at the side of running out of the pulley 110, the yarn thread is temporarily hooked by the protuberances 113. There arises a difference in the twisting momentum between the yarn thread portion hooked by the protuberances 113 and the yarn thread portion sliding on the inner walls 112 of the groove 111.
  • the number of the protuberances 113 may be provided two or more on each of the inner walls 112 of the groove 111.
  • Figure 7 shows a third embodiment of the invention in which a general pulley 120 is used which has a groove 121 V-shaped in cross section. Inner walls 122 of the groove 121 sporadically milled to have a plurality of cut-out portions 123 which has substantially flat surface. The cut-out portions 123 may be formed into recesses.
  • the yarn thread When the yarn thread encounters the cut-out portions 123 at the side of feeding it to the pulley 120 and at the side of running out of the pulley 120, the yarn thread is temporarily freed from the contact against the inner walls 122 of the groove 121. There arises a difference in the twisting momentum between the yarn thread portion freed from the contact against the inner walls 122 and the yarn thread portion sliding on the inner walls 112 of the groove 111. This is all the more effective by dispersing the cut-out portions 123 so that the yarn thread portions may not encounter the cut-out portions 123 concurrently at the side of feeding it to the pulley 110 and at the side of running out of the pulley 110.
  • the number of the cut-out portions 123 may be provided two or more on each of the inner walls 122 of the groove 121.
  • Figure 6 shows a fourth embodiment of the invention in which a pair of guide rollers 4a, 4b are provided to introduce the threads 2a, 2b upwardly.
  • an upright bracket 100a On the frame 100A of the doubling machine 100, an upright bracket 100a is provided whose upper end has an upper guide roller 6. Between the upper end and lower end of the upright bracket 100a, an intermediate guide roller 6a is provided.
  • the support guide 100 On the frame 100A, the support guide 100 is placed which includes the pulley 11 in the same manner as described in the first embodiment of the invention.
  • a yarn cutter 6A is suspended between intermediate guide roller 6a and the support guide 100.
  • Fig. 9 shows a fifth embodiment of the invention in which the yarn cutter 6A serves to unite the threads 2a, 2b together which are introduced from the tension pulleys 3a, 3b.
  • the threads 2a, 2b are united together by running them through a guide slit 6B of the yarn cutter 6A, and forming the yarn thread 5 which runs through the pulley 11 of the support guide 100.
  • the general pulleys 110, 120 may be used instead of the pulley 11.
  • the positional relationship among the threads, the yarn thread and the pulley of the support guide can be altered insomuch as the axis of the support guide may be inclined such that the yarn thread slidingly runs along the inner wall of the pulley or the inner wall of the flange.
  • a single thread may be wound up by a cylindrical package. Otherwise, three threads may be united together.
  • the yarn thread may be wound up by a spool in lieu of the doubling machine.
  • the ceramic pulley may be rotationally supported directly by the axis 11A to form an oilless bearing structure.
  • a cylindrical wind-up drum may be used which is driven discretely by a traverse mechanism.
