Definitions

  • the apparatus of this character uses an ingeniously constructed driving mechanism which is costly and intricate and which usually involves a difficulty in properly regulating the torque on the yarn beam and accordingly the tension in the yarn throughout the varying operational conditions of the loom. Apparently, this is because of the fact that the torque exerted by the weight is indirectly transmitted to the yarn beam.
  • a tension regulating apparatus having, in addition to the above described basic construction, a position adjusting mechanism which includes a worm wheel rotatable with the yarn beam and the aforesaid gearing means, a worm meshing with the worm wheel and rotatably supported on the support structureand driving means for driving the worm substantially in synchronism with the loom when the worm wheel is driven by the yarn beam at a speed higher than the speed of rotation of the worm during operation.

  • apparatus of this invention constitutes part of a loom which includes a yarn beam 20 and a back-rest roller 21 positioned in parallel to the yarn beam.
  • the yarn beam 20 has a pair of flanges one of which is indicated at a and carries thereon warp yarns 22, as seen in FIG. 1.
  • the yarn beam 20 is rotated about a shaft 23 so that the warp yarns 22 are unwound therefrom.
  • the warp yarn 22 are passed to healds (not shown) of the loom through the back-rest roller 21, as customary.
  • the tension regulating apparatus according to this invention is generallyv intended to regulate the tension in the warp yarns 22 thus fed from the yarn beam 20.
  • the tension regulating apparatus of this nature includes a spur gear 24 mounted on the shaft 23 so as to be rotatable with the yarn beam 20.
  • This spur gear 24 meshes with a pinion 25 which is mounted on a shaft 26 extending substantially in parallel to the shaft 23 of the yarn beam.
  • the shaft 26 is rotatably supported by a support structure 27 through an aperture (not numbered) formed therein and carries at its leading end a helical gear 28 which is positioned outside of an upright wall (not numbered) of the support structure.
  • a threaded bar 29 having an extension 29a (FIG. 2) is supported at this extension on a block 30 and at the opposite end by a block 31.
  • the block 30 is fast on or forms part of the support structure 27.
  • Designated by reference numeral 32 is a stop member securing the toothed rack 29 to the bracket 31.
  • the threaded bar 29 is positioned substantially at a right angle to the shaft 26 and is usually associated with a guide rod 33 extending below and substantially in parallel to the toothed rack.
  • This guide rod 33 is secured at both ends to the blocks 30 and 31 by means of bolts 34 and 35, respectively.
  • a guide piece 36 engages with the threaded bar a 29 through an internally threaded bore 36a formed therein and is slidably supported on the guide rod 33 through a finished bore 36b which is also formed in the guide piece.
  • An adjustable weight 37 depends from this guide piece 36 through a rod 38. This weight 37 may be replaced, if preferred, with suitable resilient means such as a spring which is seated on or connected to any structure member of the loom.
  • the threaded bar 29 has mounted on its extension 29a a helical rack 39 which is rotatable around this extension and which meshes with the helical gear 28 on the shaft 26. A torque exerted by the weight 37 is thus transmitted to the yarn beam 20 through the threaded bar 29, helical rack 39, helical gear 28, pinion 25 and gear 24 in this sequence.
  • the helical rack 39 has formed at its outer end a clutch half 39a through which it is engageable with an opposed clutch half 40 which is axially slidably mounted on the extension 29a of the threaded bar.
  • the clutch half 40 may be splined to the extension 29a or otherwise axially movably supported on the extension 290 through a key 41 as illustrated in FIG. 2.
  • This clutch half 40 is thus rotatable with the threaded bar 29 through the cooperating clutch flange 39a.
  • a disc 42 having an operating knob 42a is secured to an end portion of the extension 29a by a bolt 43 so that the threaded bar 29 can be manually rotated about its axis.
  • the adjustable weight 37 which has been moved toward the block 30 during the preceding operation should be moved to the block 31 by manually turning the disc 42 at the knob 42a so that a maximum torque is applied to the yarn beam 20 from the weight 37.
  • the gear 24 rotates with the yarn beam 20 in the direction of arrow A and drives the pinion 25 and helical gear 28 to turn.
  • the helical rack 39 which is rotatable around the extension 29a of the toothed rack, is thus driven by the helical gear 28.
  • the diameter of the roll of the yarns on the beam 20 decreases and concurrently the tension in the yarns unwound from the beam increases progressively so that it becomes necessary to reduce the torque on the yarn beam, as previously noted.
  • the driving means 64 is shown to include a stationary flange or bracket 66 which is fast on the frame structure of the loom and which has a bored boss 66a and a stationary shaft 66b received therein.
  • a rotary driving disc member 67 having a boss 67a is rotatably and axially slidably mounted on the shaft 66b through a bush 68.
  • a sleeve 69 having a collar portion 69a is fast on the outer peripheral wall of the boss 67a of the rotary driving disc member 67 through a key 70.

  • a sprocket wheel 72 is secured to an outer peripheral wall of the collar portion 69a of the sleeve.
  • the rotary driving disc member 67, sleeve 69 and sprocket wheel 72 are all rotatable together about the shaft 66b.
  • the sprocket wheel 72 is associated with a driving sprocket wheel 72 through a chain 73, as seen in FIG. 4.
  • the driving sprocket wheel 72 is driven from the loom per se.

  • the driven means 65 is shown to include a rotary driven disc member 75 which is supported on a rotary shaft 76 through a bolt 77.
  • This shaft 76 is positioned in an approximately upright position and substantially at a right angle to the shaft 66b of the bracket 66 of the driving means 64, as shown.
  • the rotary driven disc member 75 of the driven means 65 is in frictional contact at its circumferential edge with an outer face of the rotary driving disc member 67 preferably through a frictional member 78.
  • the shaft 76 is rotatably supported intermediately by a bearing 79 and at its lower end portion by a bearing 80.
  • the bearing 79 is supported on or forms part of a supporting arm 81 which extends from the stationary bracket 66 of the driving means 64, while the bearing 80 is supported on or integral with the support structure 27.

  • the rotary driving disc member 67 drives the rotary driven disc member 75 of the driven means 65 through the frictional member 78. It is, in this instance, apparent that the speed of rotation of the rotary driven disc member 75 depends upon the radial distance between the center of the disc member 67 and the contact point between the two rotary disc members, namely, upon the position of the rotary driven disc member 75 relative to the center of the rotary driving disc member 67.
  • the rotary driven disc member 75 now drives the third or driving bevel gear 82 through the shaft 76 and this bevel gear, in turn, drives the first or driven bevel gear through the second or intermediate bevel gear 62.
  • the rotational force is in this manner transmitted to the worm 54 through the shaft 55 extending from the bevel gear 60 so as to finally drive the worm wheel 53, whereby the rotational or angular deviation of the support structure .27 in the direction of arrow B can be remedied or compensated for by the rotation of the worm wheel 53.
  • the shaft 76 of the driven means 65 is in this manner lowered to its initial position so that the worm 54 is now It is to be noted that the frictional contact between the rotary driving and driven disc members 67 and 75, respectively, is not impaired by the upward and downward movements of the'shaft 76 because the shaft 76 is axially slidably supported by the bearing 79 on the supporting arm 81 and because the rotary driving disc member 67 is constantly urged toward the driven rotary disc member 75 by the action of the compression spring 74.
  • FIGS. 7 to 11 A modified example of the position adjusting mechanism applicable to the apparatus illustrated in FIGS. 1 to 3 is shown in FIGS. 7 to 11.
