Definitions

  • the present invention relates to a process for the beaming and winding of thread bolts and material Webs in which the winding mechanism is driven by a motor controllable in its rate of revolution and the unwinding mechanism is braked with variable moment.
  • the general technical problem basic to the present invention consists accordingly in finding a process for the rewinding and winding of thread bolts and material webs which, at all winding speeds, and in particular at very low speeds as well as at standstill, guarantees a constant thread pull with changing diameters of the material carriers and, furthermore, when the drive is switched off, holds the threads taut.
  • the special technical problem also lies in providing a simple process and one assuring low susceptibility to breakdowns.
  • the motors or motor groups are coupled with one another in such a way that the turning speed difference between the driving and driven parts of the coupling is kept within a range of constant or approximately constant torque, independent of minor fluctuations in the turning rate dilference. If the exciter current is varied in dependence on the winding diameters, then constant thread tension may be attained during the entire winding process.
  • the speeds of the two motors or motor groups can be attuned in such a way thatwith suitable choice of the coupling characteristic curvethe brake motor stands at the highest winding speed (turning rate), but for the maintenance of the torque is supplied with a corresponding rest current, while with the winding motor at a standstill the brake motor turns at maximum speed and thus also in this operative state maintains the desired thread tension. It is possible, for example, for both motors or motor groups to be provided with current by way of a voltage divider, so that the voltages on the two groups are dependent upon one another in a simple relationship.
  • FIGURE 1 shows a schematic circuit diagram of the oppositely directed turning rate control making use of a voltage divider
  • FIGURE 2 shows the appertaining diagram of the voltage course for the drive motor and the brake motor
  • FIGURE 3 shows a rewinding (beaming) drive similar to FIG. 1 with current supply over magnetic amp1ifiers or controllable Si-thyratrons;
  • FIGURE 4 shows the diagram of the appertaining voltage course
  • FIGURE 5 shows the basic circuit diagram of a drive for warping machines with direct current shunt Wound motors which are fed over magnetic amplifiers;
  • FIGURE 6 shows the basic circuit diagram of a warping machine drive with three-phase current commutator machines and mechanical shaft for the brake coupling
  • FIGURE 7 shows the torque characteristics of an especially well-suited eddy-current coupling.
  • the winding part 1 is driven by motor 4.
  • An electromagnetically actuated braking means 2, 3, which becomes active when the machine is shut off, is connected with the drive shaft.
  • the unwinding part 5 is driven by motor 9 over the interposed slip coupling 8, in the present case an eddy-current coupling.
  • Braking means 6, 7 is connected with the shaft, between the slip coupling 8 and the unwinding part.
  • the exciter current of slip coupling 8 is varied by the regulating resistor 10, 13.
  • the adjustable slide contact 13 is connected by lever 11 with a sensing roller 12, which senses the thickness of the unwinding part.
  • Both motors 4 and 9 are directcurrent shunt motors which are energised through two rectifiers 19 and 20, said motors having shunt field Windings 23 and 24.
  • the current supply comprises a transformer 15 with movable middle tap 16, 26.
  • the shifting of the tap is done by means of a shifting motor 14, in such a way that movement of the tap in the direction of arrow 17 increases winding speed], while movement in the direction of arrow 18 reduces winding speed.
  • the movements of the voltage tap 16, 26 are limited so that, in both end positions, a residual voltage 31, 32 is provided, in each case for the motor energised at the lower voltage. This is necessary so that the torque necessary for the maintenance of the thread tension will be applied.
  • a conventional current limiter 25 for starting purposes is installed in the supply line for the brake motor 9. The current-main voltage is applied at 21 and 22.
  • the slip coupling 8 can include stationary adjustable guide blades of the usual type and an additional control device 12 is connected with the adjusting device for the guide blades.
  • the voltage variation can be clearly seen from FIG. 2, wherein the straight line 27 shows the voltage between 26 and 22, while the straight line 28 shows the voltage between 26 and 21.
  • the lateral limits 29 and 30 correspond to the end positions of the voltage tap 16.
  • Numbers 31 and 32 indicate the standstill voltages for the two motors 9 and 4.
  • the turning rates of the two motors vary according to the known turning rate equation:
  • the two braking means 2, 3 and 6, 7 securely hold the warp beams in order to prevent slacking of the thread. It is expedient to arrange a time lag between the starting of the motor 9, when the slip coupling 8 goes into action, and the release of the braking unit 6, 7, so that unit 6, 7 is released only when motor 9 and slip coupling 8 have reached their starting speed of revolution.
  • FIG. 3 likewise shows winding part 1 with drive motor 4 and braking means 2, 3, and an unwinding part with drive motor 9, slip coupling 8 and braking unit 6, 7.
  • a potentiometer 37 In addition to the alteration of the excitation as represented in FIG. 1 for the eddy-current coupling 8 there is here arranged a potentiometer 37, with the aid of which, for example, the optimal thread tension can be set in, generally difierent with differing denier.
  • a potentiometer 33 on which tap 34 controlled over feeler roller 36 in dependence on the diameter of the winding part acts in such a way that the winding speed remains constant.
  • the control of the two motors takes place in a manner known per se over magnetic amplifiers or silicon controlled thyratron power amplifiers 39, 41 together with the common control set 40.
  • the apparatus is dimensioned in such a way that the desired voltage course is achieved in both machines.
  • the curves 44 and 45 in FIG. 4 show the voltage course for the motors 4 and 9. Over the potentiometer 33 it is possible to influence either the control set 40 or the two fields 23 and 24.
  • FIG. 5 shows the theoretical circuit diagram of a drive for warping machines.
  • the run-off beams 5 arranged one behind the other are connected over eddy-current couplings S with drive motors 9, which lie in parallel on the output voltage of the power (output) amplifier 39. Otherwise, the circuit is built up as in FIG. 3.
  • FIG. 6 shows a variation of the drive for warping machines with two three-phase current commutator motors as drive machines, in which for all the unwinding parts in common there is present a brake motor 47, which drives the eddy-current couplings by means of a shaft 50, over bevel wheel gears 51, 52.
  • the brake motor is a threephase current commutator motor the speed of which is controllable, for example, through brush cross shifting.
  • a second three-phase current commutator motor drives the winding part,
  • the speeds of the two machines are varied by a common shifting gear 48 proportionally and oppositely.
  • Starting resistors 49 serve in the usual manner to limit the starting current.
  • short-circuit rotor motors with an infinitely adjustable gear between motor and driven or braked part.
  • the infinitely shiftable gears must be arranged in such a way that the output turning rates automatically vary oppositely.
  • short-circuit rotor motors it is also possible to employ socalled static frequency transformers, in which the turning rate can be regulated by continuous shifting of the output frequency.
  • FIG. 7 shows the characteristic torque diagram of an especially Well-suited eddy-current slip coupling, in which the torque transmitted in each case at a certain exciter current strength is plotted in dependence on the effective differential turning rate or the slip.
  • Apparatus for beaming and rewinding comprising the combination, with an unwinding reel and a rewinding reel, of variable speed motors drivingly connected respectively with the rewinding and unwinding reels, a slip coupling interconnecting the unwinding reel with its driving motor, means for varying the slippage of said coupling as a function of the amount of material on the unwinding reel, and voltage means comprising a winding having a shiftable tap, the movement of which is limited, in each of its opposite end positions of adjustment to apply a standstill potential on the motors sufiicient to maintain a desired thread tension.
  • Apparatus for beaming and rewinding comprising the combination, with an unwinding reel and a rewinding reel, of variable speed motors drivingly connected respectively with the rewinding and unwinding reels, a slip coupling interconnecting the unwinding reel with its driving motor, means for varying the slippage of said coupling as a function of the amount of material on the unwinding reel, a power amplifier for energising each motor, a common control set associated with said amplifiers for increasing the voltage on one motor while correspondingly decreasing voltage on the other, and vice versa.
