Definitions

  • the invention relates to a thread delivery device for textile machines with a rotatable thread storage part according to the preamble of claim 1.
  • the thread storage part is designed as a storage drum on which the thread in several turns for temporary storage and for forwarding the thread by winding or pulling it off the thread storage drum is arranged.
  • the term "thread” used here also means yarns, wires, ropes, cords, tapes or other continuous strand material.
  • the thread storage and delivery devices of the aforementioned patents have one or two thread storage drums or spools for: winding and unwinding the thread, taking precautions that the thread turns are on the drum move continuously in the axial direction from the thread take-up point to the thread take-off point.
  • a disc or a similar drive element is coaxially fixedly connected to the thread storage drum or thread storage spool in order to receive a rotary movement from the assigned textile machine or other machine in order to achieve winding and unwinding of the thread synchronously with the operation of the assigned machine.
  • thread storage and delivery devices One of the important purposes of such thread storage and delivery devices is to continuously store a small amount of the thread running off, so that in the event of a thread break between the thread delivery point and the textile machine, by means of suitable thread monitoring devices, the machine can be switched off before the end of the broken thread is drawn into the textile machine and can therefore no longer be connected by tying or otherwise connected to the broken end of the thread on the supply side.
  • thread delivery devices hereinafter referred to as thread delivery devices for short, are usually provided with a thread monitoring device, which is generally called "thread monitor", in order to detect a break in the running thread.
  • thread monitor In many known thread delivery devices, such a thread monitor is arranged in the thread passage direction in front of the storage drum, often a second thread monitor is also provided in the passage direction after the storage drum.
  • these thread monitors can often also switch off the textile machine for no apparent reason if the incoming thread has not broken, which is generally referred to as incorrect switching off. It is not fully known and understandable why such a false shutdown occurs and there are inconsistent opinions among experts in this regard, but it is assumed that natural tension fluctuations and vibrations in the moving thread between the thread supply point and the thread supply device sometimes cause a sufficient adjustment at the upper thread monitor to trigger a shutdown of the assigned textile machine.
  • a number of known thread delivery devices are provided with spring-loaded tensioning disks or similar thread brakes, through which the running thread is passed before reaching the thread delivery device and in front of the thread monitor.
  • the aforementioned U.S. Patents 3908921; 3,928,987; 3 952 554 and 4 106 713 show exemplary embodiments of such disk-like thread brakes in known thread delivery devices. It is assumed that these thread brakes are essentially only used to tension the thread in the area of a thread monitor and thereby to prevent incorrect switching off.
  • Disc brakes such as those shown in the aforementioned patents and other similar braking devices, cause additional thread tensions due to the friction they exert on the thread and which cause deleterious chafing and fiber build-up when processing spun threads, yarns or similar strands made from textile fibers , as well as occasional thread breaks if the thread tension level becomes too high.
  • Fluff production and accumulation only worsen existing environmental problems in many textile factories and also cause quality control problems by promoting the appearance of fiber rovings or knots. It is best to periodically remove the fluff accumulation on the braking devices, sometimes stopping the associated textile machine and reducing the production output and the efficiency of the machine accordingly.
  • the invention has for its object to provide a thread delivery device of the type mentioned in such a way that the occurrence of false shutdowns of the associated textile machine is prevented without a thread brake or any other device exerting additional tension on the running thread is required.
  • the object is achieved with a thread delivery device according to claim 1.
  • the inventive design ensures that the shutdown device is unaffected by thread tension changes that occur on the thread in the direction of travel before the first circumferential area, and only actual thread breaks are found.
  • the thread delivery device can preferably have a first and a second storage drum, the periphery of which in each case forms one of the two peripheral regions and which are arranged coaxially at a distance and are firmly connected to one another for a synchronous rotary movement.
  • An arrangement of pulleys arranged coaxially to the storage drums can expediently be provided for the drive.
  • the thread guiding device can advantageously be designed such that the thread is fed essentially tangentially and is also essentially tangentially derived from the peripheral region of each drum.
  • the monitoring switch-off device as a thread monitor advantageously has a pivotable arm which rests with its weight on the running thread in the area between the first and the second storage drum and which falls down under the force of gravity when the tension in the monitored thread running area is lost.
  • an additional thread monitor for monitoring the thread in the direction of passage can be arranged after the second thread storage drum in order to determine thread breaks that occur in the area between the thread delivery device and the textile machine.
  • a rotatably mounted head part can be provided, from which an arm carrying a thread guide eyelet extends outwards and with which the thread passed through the eyelet can be wound onto the storage drum if the head part facilitates filling of the thread supply device is rotated.
  • thread delivery device hereinafter referred to as thread delivery device for short, is generally designated by the reference number 10. It has a carrier 12 for a thread storage part 14 and a drive pulley arrangement 16, which are rotatably mounted on it together. An arrangement of thread guiding elements, generally provided with the reference number 18, is also fastened to the carrier 12, by means of which the thread running path is determined by the thread delivery device 10 and a thread monitor device, generally designated by the reference number 20, for determining thread breaks.
  • the carrier 12 consists of an arm 22, at the rear end of which a downwardly open recess 24 is provided for receiving a suitable support part 26, for example for receiving a support rail or a support ring as parts of a mounting device for the thread feed which is customary in circular knitting machines.
  • a threaded bore 28 opens into the recess 24 and serves to receive a grub screw 30 with which the arm 22 can be clamped to the support part 26.
  • the drive pulley assembly 16 is conventionally comprised of a pair of pulleys 32, each of which has a plurality of axially extending teeth 34 evenly spaced about its circumference, which engage a toothed belt 36 or toothed belt as a common drive means in circular knitting machines.
  • the two pulleys 32 are rotatably supported coaxially adjacent to one another by means of ball bearings 40 on a central shaft 38.
  • a clutch disc 42 is fastened between and coaxial with the pulleys 32 so that it can be adjusted in the axial direction between the two pulleys 32 in order to selectively come into frictional connection with one or the other pulley and thereby the relevant pulley 32 to rotate with the shaft 38.
  • the pulleys 32 have different diameters so that the shaft 38 can be operated at different speeds.
  • the shaft 38 protrudes on both sides beyond the two pulleys 32 and is rotatably supported with its lower end region in the arm 22 of the carrier 12 by means of a bearing 44 formed in the arm 22, which holds the shaft 38 in an upright position in which the pulley arrangement is 16 is located directly above the arm 22.
  • the thread storage part 14 has a pair of storage drums 46, one of which is fixedly connected to the projecting lower end of the shaft 38 and is arranged immediately below the arm 22, while the other is connected to the projecting upper end of the shaft 38 immediately above the upper pulley 32 is firmly connected.
