Definitions

  • ABSTRACT A reciprocating yarn guide having a variable path comprising a carriage which is driven with a reciprocating movement, at least three pulleys mounted on the carriage, at least one belt tensioned around these pulleys, a yarn guide attached to the belt, a position member attached to the belt, and a position adjusting member, the position member being slidably attached to the position adjusting member.
  • This invention relates to a variable path reciprocating yarn guide. More particularly, this invention relates to a reciprocating yarn guide wherein the variable path of the guide may be easily and quickly varied.
  • Variable path reciprocating devices are utilized in a great number of industries and especially in the textile industry for guiding a yarn to be wound up on a suitable support.
  • These variable path devices basically comprise a linear reciprocating carriage having two arms projecting from the carriage at right angles to each other. One of the arms has the yarn guide attached to it, while the other arm engages a position adjusting bar which may be variable inclined or adjusted.
  • position adjusting bars are often called sine bars since they cause the path of travel to vary.
  • the yarn describes a partial arc of a circle which is not completely satisfactory for the proper formation of a wind up coil.
  • such apparatus comprises a carrage, means for driving the carriage in a reciprocating motion, at least three pulleys mounted on the carriage, at least one belt mounted on these three pulleys, a yarn guide attached to the belt, a position member attached to the belt and a movable position adjusting bar, the positioning member being slidably attached to the movable position adjusting bar.
  • the primary object of the present invention to provide a reciprocating textile winding apparatus wherein the length of the reciprocating path of the guide member can be easily adjusted.
  • FIG. I is a diagrammatic view of the device in accordance with the present invention.
  • FIG. 2 is a detailed view of the position adjusting or sine bar
  • FIG. 3 and 4 are diagrammatic views illustrating the operation of the device of the present invention.
  • FIG. I shows a diagrammatic view of the apparatus of the present invention which includes a carriage I mounted for reciprocating movement on two parallel guide bars 2 and 3.
  • Carriage 1 is driven in a reciprocat ing movement by any conventional reciprocating drive 4, such as a motor driven, cam and follower, or link and pin type arrangement.
  • Mounted on carriage I are three pulleys 5, 6 and 7. Although three pulleys are shown in FIG. 1, any number of pulleys greater than three may be utilized as long as at least one pulley is not in line with the other pulleys. Furthermore, it is preferred that the three pulleys are spaced so that the distance between pulleys 5 and 6 and between pulleys 6 and 7 are approximately equal.
  • a belt 8 Stretched around pulleys 5, 6 and 7 is a belt 8 which can be any inextensible or nonstretchable flexible belt.
  • a suitable pulley belt is one made from a fabric reinforced rubber.
  • Belt 8 may either by smooth or may have a series of notches. When belt 8 is notched, each of pulleys 5, 6 and 7 have a series of lugs, each lug being separated corresponding to the spacing between the notches in belt 8.
  • one of the pulleys, especially pulley 7 may be adjustable so that the tension on belt 8 may be changed. This adjustment may be effected by any conventional arrangement.
  • the pulley 7 may be mounted in a slot 20 formed in the frame 1, in which an adjustment screw 21 disposed to move normal to the axis of the pulley 7 is threaded. Upon advancing the screw toward the axis of the pulley 7, tension in the belt 8 is increased. Upon backing the screw 21 away from the axis of the pulley 7, tension in the belt 8 is described.
  • yarn guide block 10 Mounted on carriage 1 parallel to guide bars 2 and 3 is in additional guide bar 9. Mounted on guide bar 9 is a yarn guide block 10 having a guide member or nip 11 attached thereto. Yarn guide block 10 is also firmly attached to belt 8 so that any displacement of belt 8 also displaces yarn guide block 10.
  • slotted guide member 12 Also mounted on carriage I in a direction perpendicular to guide bars 2 and 3 is a slotted guide member 12.
  • Slotted guide member 12 has an elongated slot 13 perpendicular to guide members 2 and 3.
  • the path of travel of belt 8 between pulleys 6 and 7 is parallel to the sides of slot 13 and is roughly intermediate the sides of slot 13.
  • Attached to belt 8 between pulleys 6 and 7 and projecting through slot 13 is a position member 14.
  • position member 14 is firmly fixed to belt 8 so that any movement of belt 8 is reflected in position member 14 and vice versa.
  • the upper end of position member 14 sits within channel position adjusting bar 15.
  • Slidably mounted within the position adjusting bar 15 is a slide member 16 which facilitates the sliding movement of position member 14 within position adjusting bar 15.
  • Bar 15 is mounted on the wind up apparatus by means of a pivot point 17 so that bar 15 may be positioned at any angle relative to guide bars 2 and 3.
  • FIG. 2 which is an underside view of position adjusting bar 15 shows the construction of slide member 16 within a generally U-shaped channel 18. Although slide member 16 may be merely placed within channel 18, slide member 16 may also be partially held in place by two parallel ribs on each side of channel 18.
  • FIGS. 3 and 4 show the apparatus of the present invention in use and demonstrate how the variation in the angle or inclination of position adjusting bar 15 affects the length of the path of travel of yarn guide block 10.
  • a reciprocating device having an adjustable path comprising a carriage, means to drive said carriage with a reciprocating movement, at least three pulleys mounted on said carriage, a belt mounted on said pulleys and forming a first run parallel to the direction of movement of said carriage and a second run perpendicular thereto, a yarn guide attached to said first run, a position member attached to said second run, and a position adjusting bar adjustably mounted relative to said carriage, said position member being slidably attached to said position adjusting bar.
