Definitions

  • Synthetic yarn wound by conventional machines often undergoes changes in characteristics, especially near the ends of the yarn package. This is especially true where the yarn package has tapered ends. As a result of these changes in characteristics, a fabric made up from this yarn will have streaks which make it unusable. In order to eliminate these streaks, which are commonly referred to as pirn taper barr, the user of the yarn must reprocess it before usage. This of course, is timeconsuming and expensive. It has been found that pirn taper barr is eliminated when the yarn is traversed at a high speed during winding. In order that the speed be maintained in the most critical area of the package, it is highly desirable that the traversing speed be maintained uniform near the ends of the traversing stroke.
  • One of the disadvantages of machines used in the past for traversing yarn being wound onto a bobbin is that the traversing speed is decreased substantially near the ends of the traversing stroke.
  • Conventional winding machines have also had the disadvantage of having the yarn traversing member lag or rest at the ends of the traversing stroke until the backlash present in the machine was taken up, resulting in an undesirable accumulation of yarn at the ends of the package.
  • one of the objects of the invention is to provide a novel and improved yarn traversing mechanism.
  • Another object of this invention is to provide a mechanism for traversing a yarn at a high speed.
  • a further object of this invention is to provide a device for traversing a yarn at a uniform speed without a lag or period of rest at the ends of the traversing stroke.
  • Still another object of this invention is to provide a device wherein a traversing block is reciprocated by a moving belt.
  • a still further object of this invention is to provide a traversing mechanism having a traversing member which is alternately locked to opposite spans of a moving belt sby opposed pistons operated by means of compressed an.
  • One of the embodiments of this invention contemplates a traversing mechanism wherein a traversing block carrying a ring traveler is provided with a gripper block which is adapted to cooperate with the traversing block in alternately gripping opposite spans of a moving belt in such a manner that the traversing block is reciprocated at a high and uniform speed.
  • a pair of pistons mounted in the traversing block and controlled by a snap action valve operate the gripper block.
  • the snap action valve is operated by a pair of spring-loaded levers mounted on a pair of stop members, to thereby reciprocate the traversing block.
  • FIGURE 1 is a perspective view of one embodiment of the invention showing the general layout of the various elements
  • FIGURE 2 is an enlarged cross-sectional view taken on line 22 of FIGURE 1 showing pistons which operate the gripper block;
  • FIGURE 3 is a sectional view of the traversing mechanism taken on line 3-3 of FIGURE 2 showing the configuration of the air valve which controls the pistons;
  • FIGURE 4 is an enlarged end view of a lower stop member which serves to reverse the direction of the traversing member showing the structure of the reversing mechanism carried by the stop member;
  • FIGURE 5 is a fragmentary rear View showing the position of the lower air valve actuating lever just prior to actuation.
  • FIGURE 6 is a view of the structure of FIGURE 5 just after the lower valve actuating lever has operated the valve to reverse the direction of the traversing mechanism.
  • a base 11 supporting a frame which includes guide rods 12, 13, 14 and 15 and a plate 16, the upper ends of the guide rods being secured to the plate '16 and the lower ends thereof being secured to the base 11.
  • traversing mechanism 21 slidably mounted on the guide rods 12 and 13 carries a traveler ring 22 (FIGURE 2) of a well-known type which is positioned concentrically with a rotating bobbin 26 for directing yarn onto the bobbin in a well-known manner.
  • a lower stop member 23 and an upper stop member 24 slidably mounted on rods 25 and 26 control the reciprocation and length of stroke of the traversing mechanism 21.
  • Pulleys Z7 and 28 mounted on the base 11 and the plate 16, respectively, support a v belt 29 which is adapted to reciprocate the traversing mechanism 21.
  • the traversing mechanism 21 includes a traversing block 30 (FIGURES 2 and 3) having a bore 31 for receiving the guide rod 12 and a slot 32 for receiving the guide rod 13, the block 30 being slidably mounted on these guide rods.
  • the pulleys 27 and 28 are so positioned that the belt 2h passes through openings in the block 30, with the left span of the belt 29 being adjacent to a surface 35 (FIGURE 2) on the block 36 and the right span of the belt 29 being adjacent to a surface 36 of the block 30.
  • the pulley 27 is driven by a motor 40 (FIGURE 1) in such a direction that the left span of the belt 29 moves downward while the right span moves upward.
  • a gripper block 45 slidably mounted on a central portion 48 of the traversing block 3i between the spans of the belt 29 is provided with grooves 46 and 47 through which the left and right spans, respectively, of the belt 29 pass.
  • the gripper block 45 When the gripper block 45 is moved to the right (FIGURE 2), the surface 36 and the groove 47 cooperate to grip the right span of the belt 29 for moving the traversing mechanism 21 upward along the guide rods 12 and 13, the traversing block being secured to the right span of the belt.
  • the gripper block 45 When the gripper block 45 is moved to the left, the surface 35 cooperates with the groove 46 in the gripper block 45 to grip the left span of the belt 29 so that the traversing mechanism 21 is carried downward along the guide rods 12 and 13.
  • the central portion 48 of the traversing block 30 is provided with a pair of opposed bores 50 and 51 in which are positioned nylon disks 52 and 53 (FIGURE 2) and rubber cups 55 and 56 such as are used in wheel cylinders of automobile brakes.
  • the zdiSkS 52 and 53 and the cups 55 and 56 serve as opposed pistons which engage and actuate the gripper block 45.
  • Compressed air from a source 60 is passed through an inlet tube 61 and an inlet port 62 in the central portion 48 of the traversing block 30 to a valve 65 which is a part of a pin 66 mounted in a sleeve 67 secured in the central portion 48 of the traversing block 36.
  • the valve 65 is movable to direct compressed air through a port 70 (FIGURE 2) into the bore 50 or through a port 71 into the bore 51.
  • the valve 65 while connecting one of the bores 50 or 51 to the air source 60, simultaneously connects the other of these bores to an exhaust port 73.
  • the stop members 23 and 24, which serve to reverse the direction of travel of the traversing block 3%, are attached to a left span and a right span, respectively, of a cable 185 passing over pulleys 1G6 and 197 mounted on the plate 16' and pulleys 110 and 111 mounted on the base 11.
  • the cable 1 35 also passes over a pulley 142 secured to a gear 115 which is driven by a worm gear '116 in a well-known manner.
  • the pulley 142 is rotated in such a direction that the left span of the cable 105 moves upward while the right span of the cable moves downward.
  • This carries the stop members 23 and 24 slowly toward each other along the rods 25 and 26 to slowly decrease the length of the stroke of the traversing mechanism 21. This results in a yarn package having a cylindrical central portion and tapered ends.
  • a bar 78 secured to the pin 66 has attached thereto a pin 79.
  • the pin 66 with the bar 78 and the pin 79 forms a crank which is rotatably mounted in the sleeve 67.
  • a bracket 82 secured to the traversing block 30 is provided with a notch having stop surfaces 83 and 84 which limit the rotative movement of the bar 78 connected to the valve 65. It can be seen that movement of the bar 78 from one surface 83 or 84 to the other will change the position of the valve 65.
  • a leaf spring 90 secured in slots in legs 91 and 92 of the bracket 82 serves to engage the end of the bar 78 to urge the bar against whichever stop surface 83 or 84 is nearer.
  • the stop members 23 and 24 are provided with reversing mechanisms which include air valve actuating levers 120 and 121, respectively. Since these reversing mechanisms are identical, only that carried by the lower stop member 23 will be described in detail.
  • the lower valve actuating lever 12% is secured to a shaft 122 rotatably mounted on the stop member 23.
  • a collar 125 secured to the shaft 122 is provided with a pin 126 which extends on both sides of the collar.
  • a heavy spring 13% having one end in engagement with the pin 126 and the other end attached to the stop member 23 urges the lever 120 in a clockwise direction (FIGURES and 6).
  • a lighter spring 131 having one end in engagement with the pin 126 and the other end attached to the stop member 23 urges the lever 120 counterclockwise (FIGURES 5 and 6).
  • the action of the springs 130 and 131 is such that their forces are in equilibrium when the lever 120 is in the position shown in FIGURES 1 and 4.
  • the motor 40 drives the pulley 27 to move the belt 29 at a high speed, while the worm gear 116 drives the gear 115 to move the cable 105 at a low speed.
  • the gripper block 45 is moved to the right to grip the right span of the belt 29 so that the traversing mechanism 21 and the ring 22 are carried upward.
  • the traversing mechanism approaches the stop member 23
  • the leg 91 of the bracket 32 engages and pivots the lever 120 from its normal position to the position shown in FIGURE 5.
  • the lever 120 then clears the leg 91 and snaps to the position shown in FIGURE 6 to operate the valve 65, thereby admitting compressed air from the source 60 through the port 62 and into the bore 50 while at the same time connecting the bore 51 to the exhaust port 73.
  • This moves the disk 52 and the rubber cup 55 to the left relative to the central portion 48 of the block 30 to move the gripper block 45 to the left for gripping the left span of the belt 29.
  • This causes the traversing mechanism 21 to move downward.
  • the traversing mechanism 21 with the ring 22 moves upward to traverse the yarn on the bobbin 20 until the leg 92 pivots and releases the lever 121, this lever then striking the pin 79 and moving the bar 78 back into the position shown in FIGURE 5.
  • the traversing mechanism 21 and the ring 22 are reciprocated at a high speed without a decrease in traversing speed near the ends of the traversing stroke and without having the traversing mechanism lag or rest at the ends of the stroke.
  • the cable is moved to slowly elevate the stop member 23 and lower the stop member 24, thereby slowly decreasing the traversing stroke of the traversing mechanism 21.
