Definitions

  • the invention relates to a thread feed for circular knitting machines with bobbins distributed over their circumference, each of which is assigned a knot catcher and a thread deflector, which are arranged at a distance above the bobbin holder and are supported by upstanding rods, and with the knot catchers and the thread deflections in the thread running direction subsequent thread stores.
  • Such a circular knitting machine is known (for example from “ knitting and knitting technology", June 1977, pp. 309-313).
  • the vertically upstanding rods carry a ring to which are attached horizontally radially outwardly extending support arms for the knot catchers and thread deflections.
  • the knot catchers and the thread deflections which form the highest point of the thread path, are arranged at a greater distance above the bobbin carriers so that the yarn can run off the bobbins perfectly.
  • the bobbin carriers are arranged at a conveniently accessible working height above the floor, so that empty bobbins can be replaced with new bobbins as easily as possible.
  • a lay-on fork is therefore used to thread the threads or yarns into the knot catcher and to insert them into the thread deflectors at the start of operation.
  • This process is cumbersome and time consuming.
  • in the known circular knitting machine there are many essentially horizontally extending parts on which fiber fly or fluff is deposited and which have to be cleaned by blowing off. This blowing is done using ladders. The method of operation is also cumbersome and the use of ladders is associated with an increased risk of accidents.
  • the many yarn rack parts provided result in comparatively heavy soiling, which can result in defects in the fabric.
  • the invention has for its object to improve the known training so that the amount of work in the operation of the machine is reduced and that dirt and fluff are deposited to a lesser extent and can be easily and safely removed.
  • each bobbin for supporting the associated knot catcher and the thread deflection is assigned its own upstanding rod, which is easily detachably fastened by a plug-in connection approximately at the height of the bobbin.
  • the ring lying high and the radial arms extending from it are eliminated for the knot catchers and thread deflections.
  • the rods which run essentially vertically in their operating position, offer a comparatively small area for depositing fluff. Without use the rods can be easily removed from ladders or the like, so that their upper ends can also be lowered to a comfortable height for handling with the knot catcher and the thread deflector. The removed rods can not only be easily cleaned in this way, the threading of the thread into the knot catcher and the insertion of the thread into the thread deflection can be carried out effortlessly directly by hand, after which the rods are fastened again in their operating position by means of the plug connection.
  • FIG. 1 shows in a partially sectioned view in the circumferential direction a rod in the operating position with a knot catcher and thread deflection above the associated bobbin, the thread running from the bobbin through the knot catcher, via the Thread deflection up to a storage head for the thread is indicated.
  • a radial rod 1 is mounted on a carrier 3 in a radially adjustable manner with the aid of a clamping device 2.
  • a coil carrier 4 On the radial Stangelist is a coil carrier 4 with a slider 5 mounted radially displaceable and lockable by means of a screw 6.
  • a coil 8 is attached to the coil carrier 4.
  • the end of the radial rod 1 projecting radially outward beyond the coil carrier 4 or the plugged-on coil 8 is bent upward as shown by a little more than 90 °. This outer end is widened to a pin 10 of square cross section.
  • An upstanding rod 11 is plugged onto the pin 10 with a socket 12 formed on its lower end, which has a recess 13 of a square shape adapted to the pin 10.
  • the rod 11 is bent at its upper end several times substantially at a right angle, so that a thread deflection 15 is formed with a substantially horizontal deflection section 16, the two ends of which merge into upstanding rod sections.
  • the thread deflection 15, like the somewhat lower-lying knot catcher 18, which is fastened via a bracket 19 welded to the rod 11, is arranged essentially as shown in the perpendicular axis of the bobbin 4 or the bobbin 8.
  • the knot catcher 18 is designed in a known manner, so that a detailed description can be omitted.
  • the thread 20 runs from the bobbin 8 through the knot catcher 18 and over the deflection section 16 to a thread store 22 of a known type, and then for processing to be fed through the circular knitting machine.
  • the plug pin 10 and the socket 12 form a plug connection, which is easy to remove and reinsert the Rod 11 allows.
  • the pin 10 is received with little guide play in the recess 13 of the socket 12. This ensures, in conjunction with a sufficient length of the pin 10 and the recess 13, a secure and precise attachment of the rod 11 and thus the arrangement of the knot catcher 18 and the thread deflection 15. It has been shown that the weight of the rod 11 also during machine operation holds in the operating position shown, so that special measures for securing the connector 10, 12 can be dispensed with in the interest of easy handling.
