Definitions

  • the invention relates to a thread delivery device, such as is used in particular for supplying elastic threads to thread-consuming machines, such as knitting machines.
  • Thread delivery devices suitable for this purpose generally have two driven shafts arranged parallel to one another, on which at least one yarn spool rests.
  • the shafts are supported in a carrier and driven by a gear.
  • the transmission input is formed by a pulley, which is set in rotation by a driving belt provided on the knitting machine.
  • Taiwanese patent application no. 822 129 59 TWGM 90131.
  • Thread delivery devices are required for knitting machines in large numbers and supplied to knitting factories as supplier parts.
  • the thread delivery devices for shipping are usually dismantled at least to the extent that they can be packed in a space-saving manner. They must be able to be reliably assembled on site in just a few simple steps.
  • the shafts for receiving the bobbins are constructed in several parts.
  • this may affect the concentricity of the waves. While this has hardly any disadvantageous consequences for highly elastic threads, thread tension fluctuations of a periodic nature can occur in the case of less elastic threads due to runout errors in the waves, which impair the quality of the knitted fabric to be produced.
  • Thread delivery devices that can be removed to facilitate transportation are also from the EP 0742 304 A1 known.
  • This publication discloses thread delivery devices with a double-shell housing, a lower housing shell receiving the shafts provided with bearings and pulleys, while the upper housing shell forms a cover for fixing the bearings.
  • Multi-part shafts for receiving the spools are from the KR-A-2003 004 7 699 and the CN-Y-2 753 759 known.
  • CN-Y-2 709 471 describes a thread delivery device with two shafts for receiving the bobbins, in which the shafts are mounted in special bearing seats.
  • Another thread delivery device with two parallel shafts for receiving the bobbins is in the CN-A-1 749 459 described.
  • Subject of GB-A-2127050 is a thread delivery device with two parallel shafts for holding two bobbins, each resting on the two shafts, the thread spools being unrolled by the rotation of the shafts for thread delivery.
  • the inventor has set itself the goal of creating a thread delivery device which is improved in its function and can be produced more cost-effectively.
  • the yarn delivery device has, according to claim 1, two shafts for receiving at least one thread spool, the shafts being cylindrical in the longitudinal direction with seamless and seamless elements.
  • the one-piece shaft can consist of a cut-to-length standard part. It consists, for example, of steel, preferably a solid material or a hollow material. It can be provided with a wear-reducing coating and / or a hardened surface over its entire length, or only on its outer sections, which serve to hold yarn spools.
  • the waves are preferably smooth. In particular in the area of their sections for receiving the coil, they have neither bores nor depressions or the like. This ensures that the thread of a picked up spool is not damaged even if it is very sensitive.
  • the housing In connection with the design of the housing as a double-shell, essentially horizontally divided housing, the simplest installation options result, incorrect assembly, as can occur with assembled shafts, being excluded.
  • the horizontally split housing makes it unnecessary to slide the ball bearings over the ends of the shafts on site. Damage that could occur if this assembly measure is carried out improperly must be excluded, because the shaft can be delivered with pre-assembled bearings. All that then has to be done on site is to insert the unit consisting of shaft, pulley and bearings from above into the lower housing shell.
  • the bearings are preferably held on the shafts in a clamp or press fit, which is why Waves of material are provided.
  • These can be formed, for example, by punch points, wherein at least two, but better three or four punch points, which are arranged at uniform angular intervals around the circumference of the shaft, are preferably provided on each shaft for each bearing. This results in a good concentricity of the shafts and allows the ball bearings to be pushed over the shafts during factory assembly without causing damage to the shaft surface.
  • the inner rings of the bearings can have an inner diameter that slightly exceeds the outer diameter of the shafts.
  • the gear used to drive the shafts preferably comprises a first toothed belt that transmits the drive movement from a drive to the first shaft, and a second toothed belt that transmits the drive movement from the first shaft to the second shaft.
  • the first shaft is provided with a belt pulley which receives both toothed belts, a separating flanged wheel being provided between the two toothed belts. This can be axially movably supported on the pulley and held in place by the toothed belt.
  • the flanged wheel can have a toothed edge in order to be in positive engagement with the pulley designed as a toothed wheel. It is also possible to make the edge of the opening smooth.
  • the gearwheel is preferably connected to the shaft via a snap-in coupling, which can be permanently held in the engaged state, for example by a locking ring.
  • the locking coupling can be formed, for example, by one or more locking fingers formed on the gearwheel which engage in blind bores or similar recesses in the shaft.
  • the locking ring allows the fingers, which are otherwise resilient in the radial direction, to be clamped in a radially inner position, as a result of which the gearwheel is permanently connected to the shaft in a rotationally fixed manner.
  • the thread delivery device can be driven by a belt-driven pulley, or else by a drive motor. It is possible to design the thread delivery device from the start only for the drive by means of a drive motor. Alternatively, it is possible to design the housing such that it has, for example, a receptacle for an electric drive motor on its underside and an input for a belt-driven shaft on its top. Alternatively, a belt-driven or a motor-driven thread delivery device can be manufactured with one housing type. In the case of driving the thread delivery device by a drive motor, it is advantageous if this in a side of the housing facing downward in the installed position. In this position, the drive motor does not interfere with manual access to the coils or the coils themselves.
  • the drive motor of the thread delivery device can be used as a synchronous motor or as a stepper motor, e.g. be designed as a permanently excited stepper motor or as a reluctance stepper motor.
  • the drive motor is then preferably designed without any position feedback device. It is in an open control loop, i.e. operated without position control. If step errors occasionally occur, this can usually be easily tolerated.
  • the thread tension acting on the spools of thread generates a drive torque which counteracts the occurrence of step errors.
  • the drive motor can be fed from an AC voltage supply device at a constant frequency if the thread requirement is essentially constant. When starting up, the frequency can be gradually increased from zero to the setpoint.
  • the stepper motors or synchronous motors can be provided with a means that allows an asynchronous start-up.
  • Such an agent can e.g. a short-circuit ring or the like which is concentric with the axis of rotation of the rotor.
  • the drive motor can also be operated with operating voltages whose frequency is not constant.
  • the frequency of the operating voltage can be used to determine different thread delivery quantities. It can be provided that all drive motors of several identical thread delivery devices, which are mounted as a group on a textile machine, are operated from the same AC voltage source, to run in sync with each other. A central electronic control can thus specify the frequency and the speed of all drive motors.
  • the drive motors themselves then have no electronics. The devices can thus be manufactured simply, inexpensively and robustly.
  • the group of thread delivery devices with synchronous or stepper motors interconnected in this way is preferably subjected to a special operating regime. Changes in the frequency of the supply voltage are always carried out so slowly that none of the stepper motors stops. Sudden frequency changes are avoided. The change from one frequency to another preferably takes place with an s-shaped transition.
  • the drive motor has a drive shaft arranged in a vertical plane, which drives the toothed belts present in the housing via an angular drive.
  • the angular drive includes, for example, a ring gear that corresponds to the ring gear of a belt-driven thread delivery device. A high number of identical parts is achieved in this way.
  • the ring gear can sit on the outer ring of a ball bearing, the inner ring of which is held on a pin or pin arranged in the housing. This minimizes the number of shafts to be supported in the housing.
  • the pin can be held by a metal support part which also holds the drive motor and connects to the fastening clamp or is part of the same.
  • the cover is a further improvement.
  • the cover was previously expensive and large-volume. Packaging and shipping was very complex.
  • the new cover made of a flexible plastic film part can be sent in a space-saving manner and still fulfills its purpose. This is despite the fact that, in use, the yarn bobbins picked up by the thread delivery device essentially only arch over the top and leave the end faces of the yarn bobbins free.
  • a protrusion of 20 mm, for example, can be sufficient to prevent the fluff that is raining in knitting from being deposited on the bobbins.
  • the plastic film is preferably transparent so that the yarn spools can be seen.
  • the housing of the thread delivery device is preferably made of opaque plastic, again preferably without fiber. This is inexpensive and enables a smooth surface so that the device no longer has to be painted.
  • the stability of the fastening clamp is achieved by means of a sheet metal bracket that has been added subsequently. As mentioned, the sheet metal bracket can also be used to attach the motor. The heat generated by the motor can also be dissipated via the sheet metal bracket.
  • the thread delivery device is driven mechanically via a pulley and a shaft, it can be advantageous to provide a reversing gear.
  • This can be represented, for example, by a vertically displaceable input shaft or a pinion which can be displaced on the input shaft and which meshes with the ring gear.
  • the ring gear has an even number of teeth and exceeds the axial length of the By pinching the diameter of the ring gear, it is possible to switch the direction of rotation from forward to reverse without the ring wheel being released or having to be rotated in the meantime and without the yarn spools being twisted during the switching process.
  • a signal lamp on the housing at the end facing away from the housing clamp. This can indicate malfunctions, such as thread break or the like.
  • at least one self-flashing light-emitting diode is provided as the signal lamp. This achieves a higher level of attention than a light source that lights up in continuous operation.
  • a thread delivery device 1 which serves as a thread unwinding device. It is used to supply elastic or inelastic threads to textile machines, such as knitting machines, warp knitting machines, flat knitting machines, circular knitting machines and the like. It can be used to supply elastic or inelastic threads.
  • textile machines such as knitting machines, warp knitting machines, flat knitting machines, circular knitting machines and the like.
  • elastic or inelastic threads For example, it is attached to an annular holder 2, a so-called machine ring of a circular knitting machine.
  • a cable 3 is also arranged, which can contain storage lines, signal lines, control lines and ground lines and the like.
  • a fastening clamp 4 provided on the thread feeding device 1 engages over the holder 2 and the cable 3 and serves for the secure mounting of the thread feeding device 1 on the holder 2.
  • a housing 5 extends away from the fastening clamp 4, which is a two-shell plastic housing with an upper housing part 6 and a lower housing part 7 is formed. It is thus divided horizontally along a joint 8 and encloses an interior.
  • a rail 9, preferably made of metal or plastic, is held on the lower housing part 7 and extends transversely to the elongated housing 5.
  • the rail 9 is used, for example, to accommodate limiting rods 10, 11, which are held by riders on the rail 9 and project upwards as straight rods. They limit the axial mobility of yarn packages which are to be taken up by shafts 12, 13.

  • the hood 16 has, for example, a rectangular cut, and its narrow or end faces can be provided with reinforcements 17, 18, for example in the form of glued-on semicircular rods made of plastic or metal.
  • a frame 19, which for example consists of one or more wire brackets 20, 21, which are connected to the housing 5 or further wire brackets 22, 23, is used to support the hood 16, which is preferably flat in the relaxed state.
  • the ends of the wire clips 20, 21 and 22, 23 are attached to the housing 5.
  • blind holes formed in the housing 5 can be used, into which angled ends of the wire clips 20, 21, 22, 23 can reach.
  • the interior of the housing 5 is prevented from gradually filling with fluff, as is otherwise the case.
  • terminals 24, 25 serve.
  • the clamp 24 is screwed to the reinforcement 18.
  • both shafts 12, 13 each carry two ball bearings 26, 27, 28, 29 and a toothed pulley 30, 31 designed in the manner of a pinion.

This is effected by punch points 32, 33, which are arranged at regular intervals around the circumference of the shaft where the inner rings of the ball bearings 26, 27 are located. Each center point 32, 33 creates an annular wall 34, 35 of radially outwardly displaced material, as a result of which the ball bearing 26, 27 is held in a press fit when it is pushed on.
