Definitions

  • the arms carry projecting rods which extend at right angles to the planes in which drive belts are continuously driven from the machine, to permit selective vertical adjustment of thread supply apparatus to be engaged by selected ones of the drive belts.
  • the arms carry two vertical rods, one for idler pulleys around which the drive belts can be looped and the other for the thread supply apparatus itself, so that dismounting and re-mounting of the thread supply apparatus can be eliminated by mere selective engagement of the belts with the thread supply apparatus, or the idler pulleys, respectively, the thread supply apparatus itself being mounted for both vertical as well as radial adjustment on their mounting rods.
  • the present invention relates to thread supply apparatus and more particularly to thread storing devices, also known as furnishing wheels, or drums, or principless for circular knitting machines.
  • These thread supply devices are located on the knitting machine between the yarn package and the knitting feeds, that is, where the yarn is applied to the knit ting needles.
  • the cherriess are located in various horizontal planes on concentric rings secured to the machine structure, and various drive belts of differential drive speed run in the various planes, drive belts of respective speeds being applied to foundeds in dependence on the desired quantity of thread to be supplied.
  • the belts running around the machine are endless belts which are partially looped about the respective selected vegetas, the belts being driven from a common drive and each belt providing a drive to the re spectiveologies at a common drive speed, so that each discourse is driven with the same speed from the same source.
  • the respective drive belt may have more offerss in driving engagement therewith than previously, which changes the circumferential aspects of the belt, and changes its length along the circumference of the machine, unless the length of the belt itself as it runs around the machine can be readily adjusted, that is, compensated for the presence of additional Fallss. If, on the other hand, some convinceds are removed, the belt again requires re-adjustment in its length.
  • common carrier arms are provided which are mounted on a machine rail in the case of circular knitting machines on a support ring preferably by means of a quick-release clamp.
  • the arms are formed with a projecting rod on which the cherriess are mounted, individually adjustable for height as well as for projection from the plane in which the belts travel, so that their radial projection (in case of circular knitting machines) can be easily adjusted for effective driving engagement with the belt.
  • the belt itself, in accordance with a feature of the invention, is adjusted for length by running the belt around a group of idler pulleys mounted on an arm similar to the arms carrying the rods on which the cherriess are located, so that a minimum of different structures, and thus parts are necessary.
  • the arms are provided with two projecting rods, radially staggered from each other, the outer rod carrying idler pulleys and the inner rod carrying "the support arms for the folk, so that, if a century is to be disengaged, the belt can be looped about the idler pulley to be kept out of the way and requiring a minimum of readjustment of belt length.

  • FIGS. 1-3 which illustrate the invention applied to a circular knitting machine:
  • a rail in the form of a ring 2 is secured to the frame of the machine.
  • Carrier arms 1 are clamped to the rail 2 by means of a depending claw and a holding or tightening screw 4 (FIG. I).
  • the carrier arm 1 best seen in the top view of FIG. 2, is angled.
  • a vertically upstanding rod 5 is located at the tip of the angle, and a second and preferably similar rod 6 is located intermediate the length of the arm 1, for example near the apex of the angle.
  • Arm 1 may haveother shapes, forexample may be straight, bowed or the like.
  • Idle-r compensating pulleys 7 are located, in height-adjustable position to be rotatable about rod 5, for example by ball bearings whose height position on the rod 5 can be determined by a small set screw (not shown).
  • Three drive belts 8, 9, 10 run in a plane parallel to the plane of the ring 2, but staggered vertically (see FIGS. 1 and 3).
  • the rod 6 serves to secure Sachs ll thereto by means of a projecting arm 13 clamped by clamp screws 16 to a radial clamp 14 which can, in turn, be clamped to the vertical rod 6.
  • loosening and re-positioning clamp 14 vertically permits placement of ashamed 11, with its drive pulley 12, in engagement with any one of the belts 8, 9 and 10; as shown in FIG.
  • the tents' seur 11 is engaged by belt 10.
  • the secondtician (from the left) is engaged by belt 9 and the third tribe is engaged by belt 8.
  • the radial position that is the projection of the respective convinceds l1, and their drive pulleys 12 with respect to the center of the machine (or, in other words, with respect to the path of the belts 8, 9, 10) is adjustable by adjusting the length of arm 13 upon re-positioning clamp 16.
  • the representatives 11 thus can be located with respect to the belts in any desired vertical, as well as radially projecting position.
  • FIGS. 1-3 provide for three different belt drives, located in three respective vertical planes. Each noted is provided with an electrical contact which is led over a flexible cable 17 to a thread control or thread break sensing device; for interconnection, a quick-release plug-socket connection with an electrical bus system 17' is provided, bus system 17 being located along rail 2.
  • idler pulleys 20, 20 and 22 are located in vertically staggered position on an arm 1 (FIG. 2) which, in all respects, may be similar to arms 1 on which the concludeds and pulleys 7 are located.
  • the idler pulleys 20, 20 are preferably located on a transverse arm which may be tensioned, in the form of a tension balance 21, as well known, the arm itself being carried on an extension bar 23 which can be clamped in height-adjustable and radial adjustable position by locating brackets 24, 25 on rods 5', 6 similar to rods 5, 6, on arms 1.
  • arm 23 with its tension-balance pulleys 20, 20' and the terminal idler pulley 22 can be located in height-adjusted position, and the extent of projection of the arm 23, and with it the extent of the loop formed by the belt as it is looped from the main drive around the idler pulley 22 and back over the tension balance wheel 20' is likewise subject to radial adjustment.
  • Similar pulley arrangements are located, vertically staggered, for all the belts, the extent of radial projection of the arm 23 being matched to the number of practicess driven by the respective belts.
  • the adjustmentof the length of the belt in dependence on whether the belt drives a treat or not is rather small, since the radial position of the idler pulleys 7 and the adopted pulley 10 can be adjusted to be fairly similar, requiring only small adjustments of the bracket 23, to the extent that they cannot be compensated by the tension balance 21.
  • FIGS. 1a, 2a, 3a illustrates a form of the invention in which only a single support rod 6 is secured to shorter arms la which are, again, clamped to a ring 2.
  • Fournisseurs 11 are located on rod 6, to be height-adjustable and radially adjustable, as in the embodiment described in connection with FIGS. 1-3.
  • the idler pulleys 7, however, are omitted. This may result in a belt position pattern which causes some belts to pass on the inside, that is beneath other sentencess 11, as illustrated in connection with belt 8 (FIGS. 1a, 2a).
  • the length-adjustment for the belts may thus be more extensive.
  • An arm la which is straight, is clamped to rail 2.
  • brackets 34, 35 are clamped by screw clamps (not shown).
  • the brackets 34, 35 in turn carry a horizontally projecting rod 33 to which idler pulleys 30, 30' and 32 are rotatably connected, idler pulleys 30, 30' being located on a tension balance 31.
