Definitions

  • This invention relates to apparatus for changing bobbins on thread-winding machines.
  • the thread is customarily wound onto a bobbin which is rotated by frictional eng'agement with a drive roller.
  • a drive roller When the bobbin has become fully wound it is necessary to replace it with an empty bobbin.
  • Devices designed for effecting the bobbin change usually have the winding bobbin and the empty bobbin rotatably mounted on opposite ends of a support member which is in turn rotatably mounted, although normally locked, at its center on an upstanding pivot arm.
  • the upstanding arm is pivoted away from the drive roller and the full bobbin is removed sidewise from its holder.
  • the support member is then unlocked and rotated 180. After relocking the upstanding arm is pivoted back so that the empty bobbin makes contact with the drive roller.
  • the transfer of the thread from the full bobbin to the empty bobbin is made by hand.
  • the space between the bobbins in a gang must be great enough to permit sidewise removal of the full bobbin.
  • the lateral space between bobbin positions must be at least twice the length of a bobbin plus space for the bobbin supporting structure or a total of about three times the length of a bobbin.
  • a further disadvantage of the foregoing device is that the entire structure must be pivotable on the upstanding arm so that the bobbin can accommodate increasing layers of thread during the winding operation. As a result great care must be exercised by the machine operator in placing a new bobbin on the non-winding end of the support member to avoid breaking the thread on the winding bobbin and otherwise interfering with the winding operation.
  • Another object of the invention is to provide an apparatus for changing the bobbins in which the bobbins are supported in such a way that the operation of the bobbin in the winding position will not be adversely affected by the handling of the bobbin in the opposite position.
  • a further object of the invention is to provide an apparatus for changing the bobbins in which the winding bobbin is independently displaceable to accommodate increasing layers of thread.
  • Another object of the invention is to provide an apparatus for changing the bobbins in which the transfer of thread from a full bobbin to an empty bobbin is effected without the handling of the thread by the machine operator.
  • Fig. 1 is a perspective view of an apparatus'embodying the invention
  • Fig. 2 is a side elevational view of the structure shown in Fig. 1 wherein a part of the structure has been broken away to illustrate internal parts;
  • Figs. 3, 4, 5, 6 and 7 are semi-diagrammatic side elevational views similar to Fig. 2 and illustrating operation of the apparatus.
  • the objects are accomplished by an apparatus in which the bobbins are ro-. tatably mounted on upstanding arms pivotally mounted at the opposite extremities of a support member which is in turn mounted to rotate about its center. Means are provided for rotating the support member to interchange the positions of the upstanding arms and the bobbins thereon. Means are also provided for maintaining the arms in the upstanding attitude as the support member is rotated.
  • FIGS. 1 and 2 show an apparatus comprising an elongated support member 8 mounted to rotate about a stationary shaft 9 which is secured to a bracket 10.
  • a pair of substantially upstanding (slightly inclined) arms 11 and 12 are mounted respectively on rotatable shafts 13 and 14 at opposite extremities on the support member 8.
  • a pair of bobbins 15 and 16 are rotatably mounted on the free ends respectively of the upstanding arms 11 and 12. p
  • the bobbin 15 is in a winding position in frictional engagement with a drive roller 17.
  • the bobbin 16 is an empty bobbin intended as a replacement for the winding bobbin 15 When it has become fully wound.
  • a spring-urged lock member 18 holds the support member 8 in a fixed position for the winding operation.
  • Means for releasing the lock member 18 and means for rotating the support memher 8 are provided by a rack member 19 pivotally mounted on the bracket 10 and having a lever handle 20, a lock-releasing means 21 and a rack 22 engaging a pinion 23 rotatably associated with the support member 8.
  • the pinion 23 has a free-wheeling association with the support member 8 whereby the pinion looks with the support member when the pinion is rotated by a downward thrust of the lever 20 on the rack member 19, and rotates freely on the support member when the pinion is rotated in the opposite direction on the return of the rack memher to its original position by a spring 24.
  • the freewheeling arrangement may be accomplished by any conventional means such as a pawl and ratchet means wherein the pawl is pivotally attached to the support member 8 and spring-urged to engagement with a ratchet fixed to the pinion 23.
  • Means for maintaining the arms 11 and 12 in their substantially upstanding leaning attitude are provided by a planetary system of gears including a sungear 25 which is fixed to the stationary shaft 9, a pair of planet-gears 26 and 27, and a pair of intermediate gears 28 and 28 which are engagingly interposed between the sun-gear 25 and the planet gears. All of the gears in the planetary system have an equal number of teeth, i.e. a gear ratio of 1:1.
  • Coupling means are provided between each of the planet-gears and the upstanding arms. This is illustrated for the upstanding arm 12 in Fig. 2 wherein the planet-gear 27 is shown to have an arc-flange 33 engaging a cam 29 on the rotatable shaft 14. A similar structure is provided for the upstanding arm 11 so that the two arms have the same leaning attitude.
  • Figs. 2, 3, 4, 5, 6 and 7 The operation of the invention is illustrated in Figs. 2, 3, 4, 5, 6 and 7 in which are shown the relative positions of the support member, rack member and upstanding arms when a bobbin change is effected.
  • Fig. 2' the apparatus is shown in its normal winding position with arm 11 in a sufiiciently inclined position to place the bobbin 15 in frictional engagement with the drive roller 17 and thereby wind-up the thread 39.
  • the empty bobbin 16 is caused to rotate as shown by the arrow in Fig. 2 at a speed of rotation about 30% greater than that of the drive roller 17.
  • This rotation of the bobbin 16 may be effected by any conventional means such as by momentarily contacting the bobbin 16 with a drive belt (not shown).
  • This drive belt may be powered by the drive roller 17 through a transmission comprising, for example, friction rollers andstep-up gears.
  • the rack member 19 is then given a downward movement by the lever arm 20 causing the. lockreleasing means 21 to release the lock member 18 and then causing the rack 22 to engage the pinion 23 which rotates the support member 8 in a counterclockwise direction as viewed in Fig. 2.
  • the pivot arms 11 and 12 are maintained in their substantially upstanding leaning attitude.
  • FIG. 31 Another feature of the invention includes a brake arm. 31 (Figs. 1 and 2) which is spring-cushioned and pivotally mounted on the machine frameto ease or slow the approach of the bobbin to the Winding position and facilitate the desired thread breakage.
  • the bobbin arm contacts the brake arm at apoint just preceding the winding position.
  • the brake arm 31 may also be used as afeeler during normal winding to measure the inclination of the bobbin arm due to added layers of thread and accordingly adjust the movement of the thread guide (not shown).
  • a further feature of the invention includes a guide track or strip 32 (Fig. 2) for deflecting the course of. a bobbin around obstructions during a bobbin interchange.
  • the tip of the bobbin arm contacts the guide track at a point just preceding the position of the obstruction.
  • appa ratus for changing the bobbins comprising a support member mounted to rotate about a horizontal axis; a pair of upstanding arms each havin an axis fixed there with and rotatably journalled in opposite ends of the support member, each of said arms being adapted to rotatably support a bobbin; means associated with each axis of said arms, said means providing foroutward manual pivoting of said arms from the upstanding position thereof to a bobbin-removing position; means for rotating the support. member to interchange the bobbin-winding and idle positions of the upstanding arms and bobbins thereon; and means operatively associated with said 2.
