Definitions

  • the invention relates to a yarn delivery mechanism, in particular for yarn freshly dyed in different colors or sections in the yarn to be fixed, which has a revolving driven delivery wheel and an endless revolving part of the circumference of the yarn to be conveyed which presses the yarn to be conveyed. flexible pressure tape is provided.
  • Such yarn delivery plants are known. They enable high pressure due to the pressure tape attached to the delivery bike over a comparatively large circumferential length and the resulting large slip-free driving effect Yarn conveying speeds and thus correspondingly high production rates. This also applies to a limited extent to other known yarn delivery plants, in which the yarn is guided between a driven delivery wheel and an adjacent pressure roller, or else via two conveyor rollers of a slip delivery plant which are arranged axially parallel one behind the other. All these known yarn delivery plants have the disadvantage that the yarn is squeezed to a greater or lesser extent.
  • the invention is therefore based on the object of creating a yarn delivery unit, in particular for freshly dyed yarn, which on the one hand allows a high yarn conveying speed to be achieved but on the other hand strained yarn as sore as possible, especially as good as no yarn crush.
  • This object is achieved, according to the invention, from a yarn delivery unit of the type mentioned at the outset in that the delivery wheel consists of two guide disks arranged at a distance from one another, supporting the pressure band only on its edge edges, and a plurality of paddle-wheel arranged in between, which extend at least up to the circumference of the wheel and here against the middle parts of the pressure belt pressing the conveying ribs, over which the yarn is to be guided in a secant fashion with selective support.
  • the delivery wheel advantageously consists of a solid wheel body with a circumferential groove machined in the center, which is subdivided in the circumferential direction by a plurality of webs inserted into its side walls forming the guide disks and extending axially parallel and forming the conveying ribs.
  • damping pins are arranged in the circumferential groove of the delivery wheel between the conveyor webs, which are parallel to the axis and which are approximately at the level of each the yarn support points of the adjacent conveyor webs are located.
  • the guide disks on the delivery wheel are provided with peripheral teeth, of which individual teeth ge through the conveyor webs are formed, the pressure belt having a corresponding external toothing cooperating therewith.
  • the invention provides that the delivery wheel provided with webs and lateral guide disks is followed by a thread break monitor, which consists of a suction cup arranged in the immediate vicinity of the running yarn with a built-in light barrier.
  • a thread break monitor which consists of a suction cup arranged in the immediate vicinity of the running yarn with a built-in light barrier.
  • the yarn coming from the yarn delivery plant normally runs past this suction cup completely uninfluenced, whereas in the event of yarn breakage, the trailing yarn is sucked up and accumulated in the saucepan, so that after appropriate yarn accumulation, the light barrier present here responds and the delivery wheel stops.
  • a light barrier is also provided at the circumference of the delivery wheel provided with conveyor webs and lateral guide disks outside its pressure belt area, which monitors the yarn support edges of the conveyor webs and which stops the delivery wheel at these points if there is sufficient yarn accumulation.
  • the invention provides that several advantageously with conveyor webs and lateral guide disks provided delivery wheels are arranged axially parallel to each other and are to be driven via couplings by a common gear.
  • the transmission advantageously consists of axially parallel to one another, corresponding to the number of delivery wheels, by means of a common motor via toothed belts or the like. driven and provided with flywheel masses with which the coaxial delivery wheel shafts are connected to the drive via electrically controlled brake clutches or to be uncoupled therefrom.
  • the Garnannonwerk shown in Figs. 1 and 2 consists essentially of the Sctrei- by the drive motor 1 via the shaft 2, with adjustable rotational speed "reproduced L ieferrad 3 and the voltage applied to its periphery in part, to be delivered yarn on the other hand pressing, endlessly circulating pressing belt 5, the acid- and base-resistant flexible material, for example consists of a suitable plastic belt.
  • the pressure belt 5 is guided over the two advocatessröllen 6.7, the former of which serves as a belt tensioning pulley and is correspondingly adjustable, while the other Guide e g s-roll
  • the yarn 4 to be conveyed is dyed differently in sections in a space-dying dyeing device which is connected upstream of the yarn delivery unit and is not shown, and then runs over the deflection roller 8 and from there further between the pressure belt 5 and the delivery wheel 3 through over the guide roller 9 to a downstream fixing chamber 10.
  • a space-dying dyeing device which is connected upstream of the yarn delivery unit and is not shown, and then runs over the deflection roller 8 and from there further between the pressure belt 5 and the delivery wheel 3 through over the guide roller 9 to a downstream fixing chamber 10.
  • In the present Traps are fed simultaneously two yarns 4 ', 4 "lying side by side in parallel. However, it goes without saying that only one or more yarns can be dyed in this way.
  • the delivery wheel 3 essentially consists of two spaced-apart guide disks 11, 12, which the A n réelleband 5 only at its peripheral edges supported, between the guide pulleys 11,12 are at the supply wheel 3 schaufelradartig arranged conveying ribs 13 present, at least to extend into RadCSsproof and push against the central portions of the pressing belt 5, so that the yarn 4 at these conveyor ribs 13 only lies at points 13 ′ and is guided in secant form in the area of the delivery wheel 3 and the pressure belt 5, as clearly shown in FIG. 1.
  • the yarn 4 is clamped only on the individual support edges 13 'of the conveying ribs 13 and the belt 5 pressing thereon, and is thereby conveyed effectively but also gently.
  • the delivery wheel 3 consists of a solid wheel body 14 with a circumferential groove 15 machined into it in the center, for example a turned groove 15.
  • this groove 15 there are a plurality of webs 13 '' inserted into the side walls 11 ', 12' of the guide disks, which run axially parallel and which Form conveying ribs 13. These therefore divide the groove 15 in its circumferential direction Circumferential groove 15 between their conveyor webs 13 ′′ is arranged in each case axially parallel to the latter, damping pins 16 which are inserted through correspondingly aligned bores in the side walls 11 ', 12'.
  • damping pins 16 which are inserted through correspondingly aligned bores in the side walls 11 ', 12'.
  • these damping pins 16 lie approximately at the height of each the yarn support points 13 'of the adjacent conveyor webs 13 "running yarn guiding edge 4"'. These pins 16 suppress any yarn vibrations which are normally caused by the running yarn 4 running onto the rotating paddle wheel-like conveyor webs 13 ". Further, the guide discs 11 ', 12' of the delivery wheel provided even at a peripheral toothing 17, by which individual teeth are formed by the located in corresponding pitch conveyor ribs 13 ".
  • the length of the continuously rotating pressure belt 5 is advantageously chosen so that it is not an even multiple of the pitch of the rotating conveyor webs 13 ".
  • F ig. 3 shows the supply wheel 3 a, generally designated 19 yarn break detectors downstream of which consists of a connected to the suction line 20 Saugtopf 21, which is arranged in the immediate vicinity of the passing on it yarn 4 ', 4 ".
  • a light barrier 22 is installed which, in the event of yarn 4 IV accumulating in the suction cup 21 when the yarn breaks, and thereby stops the drive of the delivery wheel 3.
  • Another light barrier 23 is corresponding to Fiq. 3 still arranged on the circumference of the delivery wheel 3 outside the area of the pressure belt 5. You have the task of continuously monitoring the yarn support edges 13 'of the conveyor webs 13 "for any yarn accumulating there in the event of yarn breakage and possibly stopping the delivery wheel 3.
  • the response sensitivity of the light barrier 23 is set so that it is not already at about the Conveyor web support edges 13 'adhering seated dye residues, but only responds when several yarn turns have accumulated on what in the event of a yarn breakage in the high delivery speed of the delivery wheel occurs very quickly.
  • the A ntikband 5 is advantageously performed roll over three F mmungs- 24,25,26, wherein the Fmmunqsrollen 24,25 lie approximately diametrically near the L ieferrades thereto, while the third guide roller is adjustably disposed at a greater distance from the supply wheel 3 26 and thus also serves as a tensioning pulley.
  • a preferred multiple side-by-side arrangement of several delivery wheels 3 and their common drive is shown.
  • the delivery wheels 3 are then arranged axially parallel to one another, in such a way that their shafts 2 run coaxially to the correspondingly axially parallel gear shafts 27, which are arranged via correspondingly offset toothed belts 28 by the common motor 30 provided with a flywheel 29 at a constant speed are driven. Flywheels or masses 31 are also present on the individual transmission shafts 27.
  • the individual delivery wheel shafts 2 can be coupled or uncoupled from the transmission shafts 27 via electrically controlled brake clutches 32, 33, which can also be influenced by the light barriers 22 and 23, whereby it is ensured that the delivery wheel shaft 2 in each case decoupled is decelerated immediately after decoupling and after the coupling is accelerated as quickly as possible to the target speed without causing adverse effects on the common transmission.
