Definitions

  • one of the objects of this invention is to provide a novel and improved device for traversing yarn being wound onto a bobbin.
  • Another object of this invention is to provide a yarn traversing device having a uniform traversing speed throughout the length of the traversing stroke.
  • Another object of this invention is to provide a device for traversing a yarn at a uniform speed and in strokes which decrease in length as the yarn is wound into a package.
  • a still further object of this invention is to provide a traversing mechanism wherein a traversing block is alternately connected to difierent spans of a moving belt traveling in different directions so as to rapidly reciprocate the block.
  • One of the embodiments of this invention contemplates a traversing mechanism wherein a traversing block carrying a ring traveler is adapted to alternately grip different spans of a moving belt to reciprocate the block.
  • a gripper block movably mounted in the traversing block is cammed first in one direction to grip one span of the belt and then in the other direction to grip the other span of the belt.
  • the two spans of the belt are traveling in opposite directions and at a uniform speed so that the traversing block is reciprocated at a high speed without a decrease in traversing speed near the end of the traversing stroke.
  • FIGURE 1 is a fragmentary perspective view of a device embodying the principles of the invention showing the relationship of the various elements of the device;
  • FIGURE 2 is an enlarged sectional view taken on line 2-2 of FIGURE 1 showing a gripper block which cooperates with the traversing block to grip one side of the moving belt;
  • FIGURE 3 is a fragmentary sectional view taken on line 3 s of FIGURE 2 showing that part of the device which actuates the gripper block.
  • a frame 11 tached to the frame 11.
  • a gripper block 30 slidably mounted in a rectangular groove in the traversing block 25 is providedwith vertical grooves 31 and 32 through which'the two spans of the belt 18 pass.
  • the gripper block 34 is adapted to be moved alternately to the left to grip the left span of the belt 18 and then to the right to' grip the right span of the belt.
  • the belt 18 is driven in such a way that the left span travels downward while the right span travels upward.
  • a bar 35 slidably mounted in a groove 36 in the traversing block 25 carries a ball bearing 37 of a Wellknown type which is positioned in a canted groove 38 in the gripper block 30.
  • the bar 35 is secured to a rod 40 connected to a piston (not shown) of an air cylinder 41.
  • the air cylinder 41 is secured to a bracket 42 which is in turn attached by bolts 43 (FIGURE 3) to the traversing block 25.
  • a lower striker plate 45 and an upper striker plate 46 slidably mounted on the guide rods 26 and 27 serve to reverse the direction of travel of the traversing mechanism 21 by controlling a valve 48 secured to and carried by the traversing mechanism.
  • the valve 48 is provided with a stem having an upper portion 49 and a lower portion 5d.
  • the traversing mechanism 21 nears the lower striker plate 45, the lower portion 51; of the valve stem engages the striker plate 45 and is stopped.
  • the valve stem Upon further downward movement of the traversing mechanism 21, the valve stem is moved upward in the valve 4-8.
  • compressed air flows from a source 59 (FIGURE 1) through an inlet tube 60 connected to the valve 48, through the valve 48 and a tube 61 to the air cylinder 41 for moving the block 35 downward.
  • the striker plates 45 and 46 are connected to the screw 71 by spring loaded levers 75 having jaws 76 adapted to mesh with the threads on the screw 71.
  • the levers associated with the lower striker plate 45 are on the lower side of this plate and, consequently, do not appear in the drawings.
  • the jaws 76 may be opened to disengage the striker plates from the screw 71 so that the lower striker plate can be manually moved downward into engagement with the lower collars 65 and 66 and the upper striker plate can be manually raised into engagement with the upper collars 69 and 70.
  • the lower striker plate In operating the device to wind a yarn onto a bobbin, the lower striker plate is manually moved into engagement with the lower collars 65 and 66 and the upper striker plate 46 is manually moved into engagement with the upper collars 69 and 70.
  • the yarn is then threaded through a ring traveler (not shown) of a well-known type mounted on the ring 22 and connected to the rotating bobbin.
  • the motor 13 is then started to rotate the screw 71 at a fairly low speed and to drive the belt 18 at a high speed. As the belt 18 is driven, the left span thereof travels downward while the right span travels upward, parallel to the left span.
  • Compressed air is admitted through the valve 48 from the source 59 to the air cylinder 41 to force the bar 35 upward so that the gripper block 30 is cammed to the left to secure the traversing mechanism 21 to the left span of the belt 18, as best illustrated in FIGURES 2 and 3. This carries the traversing mechanism 21 downward.
  • the traversing mechanism 21 As the traversing mechanism 21 nears the lower striker plate 45, the lower portion 56 of the valve stem engages the plate 45, thereby operating the valve 48 so that the air cylinder 41 moves the bar 35 downward to cam the gripper block 30 against the right span of the belt 18. This carries the traversing mechanism 21 upward.
  • the upper striker plate 46 stops the valve stem to again reverse the direction of movement of the traversing mechanism 21. In this manner, the traversing mechanism 21 is reciprocated to form a yarn package.
  • the screw 71 is rotated slowly to move the striker plates 45 and 46 toward each other. Since the plates 45 and 46 are continuously moved toward each other during the winding operation, the traversing stroke of the ring 22 is continuously shortened, thereby forming a yarn package having tapered ends.
  • the yarn package is completed, it is removed and an empty bobbin is positioned within the ring 22 and the above procedure is repeated. Inasmuch as the device traverses the yarn at a high and uniform'speed, pirn taper barre is eliminated.
  • a device for winding yarn onto a rotating bobbin comprising a frame, a traversing block slidably mounted on the frame in a direction parallel to the axis of the rotating bobbin, a ring carried by the traversing block for guiding yarn onto the rotating bobbin, said traversing block having a rectangular groove parallel to the axis of the bobbin, a pair of pulleys mounted on the frame, a belt mounted on the pulleys and having a pair of spans passing through said rectangular groove parallel to said axis, a gripper block slidably mounted in the rectangular groove between the spans of the belt for cooperating with the traversing block to alternately grip said spans and thereby secure the traversing block alternately to said spans, said gripper block having a canted groove across one side thereof, a bar slidably mounted between the traversing block and the gripper block adjacent to said canted groove, an element secured to the bar and positioned in said canted groove for camming the gripper block into cooperation with the traversing block
