Definitions

  • This invention relates to textile ring twisting machines.
  • a small number of very steep windings are wound on an end bulge zone at one end of the filament package and an end bulge is wound upon said steep windings. If desired, after winding said end bulge, the filament may be wound in a few very steep windings to reach the opposite end of the package and a second end bulge may be wound on said last mentioned very steep windings at the second end of the package.
  • the pitch of the knotting windings is preferably very small and the knotting windings are wound at opposite inclinations.
  • the pitch of the knotting windings may be decreased in a damped manner.
  • An object of the invention is to provide an electro-hydraulic control of the ring rail movement of a ring twisting machine, particularly for a stretching and twisting machine, for treating strands of continuous filaments whose continuous filaments are subjected to a stretching process to increase their strength and are then twisted before they are wound.
  • an attachment for knotting the thread which is fixed to the bottom of a bobbin sleeve while the ring rail is at a standstill for a short time, cannot be applied over a fixed width if the ring rail movement is controlled by mechanical means.
  • the known hydraulic mechanisms for moving ring rails are only provided with means to ensure the raising and lowering of the ring rail at uniform speed at the beginning and end of the process of winding a cop, and this leads to difliculties in the subsequent treatment of the cop, because the windings on the cop follow a stepped path so that the thread cannot be drawn off smoothly.
  • the end piece which is wound on to the cop at the end of the winding process consists of a number of windings varying within wide limits, which again is not desirable for the subsequent treatment of the cop.
  • an electro-hydraulic device for controlling the movement of a ring rail of a textile ring twisting machine, comprising a working cylinder, a piston displaceable in the cylinder, a piston rod for transmitting movement from the piston to the ring rail, ducts leading into the working cylinder on opposite sides of the piston, a reversing valve connected to said ducts, a liquid supply pump connected to the reversing valve, a reflux duct connected to the reversing valve, a governor connected with the reflux duct for adjusting the return flow of liquid, and a valve for bridging the governor and connected in parallel with the governor which valve is opened at the beginning and at the end of a winding operation of the machine.
  • the electro-hydraulic control may have a stop valve which is actuated by the ring rail and interrupts the flow of liquid for a certain time, the valve being connected in a duct whose inflow of liquid displaces the working piston.
  • the stop valve is advantageously arranged in the duct in which the liquid is supplied to the cylinder during the upward movement of the ring rail, because in this case oscillations of the ring rail are produced at the beginning of the closure of the stop valve which oscillations secure the end of the thread moving upward from the waste bulge at the lower end of the cop.
  • the stop valve may then be bridged over by a supply rate governor adjustable to a low rate of through-flow for the purpose of producing a broad connecting bulge.
  • FIGURE 1 is a schematic diagram of a mechanism for moving a ring rail
  • FIGURES 2, 3 and 4 illustrate as a function of time the various raising and lowering movements of the ring rail for forming a cop
  • FIGURE 5 is a detail thereof
  • FIGURES 6, 7 and 8 are diagrams of electric circuits for carrying out raising and lowering movements in accordance with the programmes illustrated in FIGURES 2 to 4.
  • a ring rail 2 containing spinning rings 1 (only one of which is shown in FIGURE 1) is moved up and down by oscillating toggle levers 3 mounted on fixed pivots 4.
  • Each of these toggle levers has a roller "3' or 3" at one end, the vertically moving ring rail 2 being supported on these rollers.
  • the oscillation is imparted to the toggle levers 3 by a piston rod 5 of a piston 6 which is reciprocated by liquid in a working cylinder 7.
  • the piston 6 is controlled by a reversing valve 8 by way of ducts 9 and 10 connected to the ends of cylinder 7.
  • These limit switches 16 and 17 are connected to two separate linkages 21 and 2t), respectively, each of which is controlled by a removable cam disc 19 and 18, respectively.
  • These switches are moved up and down according to the type of package to be produced, each of the cam discs 18 and 19 being driven by its own variable speed motor M and M respectively.
  • a switching rod 22 is rigidly connected with the ring rail 2 and participates in its upward and downward movement.
  • the rod 22 is connected with a cam 23 and actuates the limit switches 16 and 17 and also a switch 24 for knotting the thread, the switch 24 being connected with a solenoid 25 of a stop valve 26 which is situated in the duct 10 and open when no current flows and is bridged over by a supply rate governor 26 which can be adjusted to zero or to small quantities.
  • the valve 26 has an armature 26.
  • the switch 17 is in its lowest position and the switch 24 whose elevation is fixed is always below the switch 17.
  • the hydraulic system comprises a tank 27 for liquid and a conveyor pump 28 which is driven by a motor M and which supplies actuating liquid to the reversing valve 8 through a duct 29.
  • a conveyor pump 28 which is driven by a motor M and which supplies actuating liquid to the reversing valve 8 through a duct 29.
  • an excess pressure valve 30 connected in parallel, a high speed valve 32 arranged in a reflux duct 31 and a flow rate governor 33 arranged in parallel for adjusting the rate of return fiow and hence the speed of raising and lowering of the ring rail in normal operation.
  • a sleeve 34 on the spindle carries a cop 35 which is in the process of being built up. To facilitate further work on the cop, a terminal bulge 36 is formed at the top and a bulge 37 at the bottom for connecting the thread by a knot.
  • waste bulge 38 which is formed at the beginning of the winding process with unstretched material which is to be excluded from subsequent treatment processes, and this bulge is removed from the spindle from time to time by the operator.
  • a number of windings can be wound on the waste bulge 38 (for further details see FIGUR-ES 4 and 8).
  • the elevation of the waste bulge 38 which is formed with the ring rail in its lowest position depends entirely on the position of an adjustment nut 39 on the cylinder 7, which represents a mechanical stop for the piston rod.
  • the terminal bulge 36 which is also necessary and which is formed at the end of the winding process, is formed when the ring rail is in its uppermost position which is determined by the position of a fork 40' secured by a lock nut 40.
  • the position of the fork 40 may be adjusted by turning the piston rod 5.
  • the lock nut 40 comes into contact with the adjustment nut 39 whose position determines the elevation of the waste bulge 38.
  • the reversing valve 8 consists of a three-step piston 41 which controls the inflow and outflow of the fluid to and from the ends of the cylinder 7 through the ducts 9, 10.
  • a vessel 42 which is open at the top and has a constricted zone 43 in the middle and is filled with con trol fluid contains the piston rod 12 together with the damping plate 11 which is in the constricted zone when in the neutral position in which the movement of the piston 6 is reversed.
  • the purpose of the damping plate 11 is to suppress the oscillations shown in FIG. 2 and occurring at the upper and lower ends of the winding.
  • FIG- URE 3 shows the effect of the damping means 11, 43.
  • the program of movement for the ring rail shown in FIG- URE 2 begins at the lower mechanical starting position UMA, in which the ring rail remains during the period t t of starting the machine. This is followed by a rise of the ring rail at high speed until the switch 24 for the knotting bulge 37 is actuated. Thereafter the ring rail 2 is kept at a standstill by a time relay 49 (FIGS. 6-8) until the time t when there is again a rapid rise until the slower normal movement is initiated by a switch 54 whose elevation is fixed.
  • the rapid rise over the sleeve 34 when the latter is still empty results in a very small number of steep windings which subsequently make it easier to draw the thread off the spool.
  • FIG. 6 shows in principle the same program of movement up to the time but the switch 54 switches to high speed for downward movement of the spindle rail at the time 1 i.e.
  • FIGURE 5 shows the effect of the supply rate governor 26".
  • this governor allows a small quantity to flow through, there will be a slight ascent of the ring rail (broken line) in spite of the fact that the stop valve 26 is closed, and the result of this is that the connecting or knotting bulge will have a certain width, which is often desirable in practice.
  • FIGURE 5 is an enlargement of the part of the diagram FIG. 4 in the zone of the connecting bulge.
  • the circuit diagram in FIGURE 6 corresponds to the program of movement illustrated in FIGURE 2.
  • the ring rail 2 is situated on the lower mechanical stop UMA.
  • the manually operated starting button 45 is pressed, current flows through the magnet 45' and the armature 46 is energized and the sequence switch 47 is turned by one notch into the starting position (shown in broken lines) whereby a voltage is applied to a starting bus-bar 48.
  • the motors M M and M are thereby started in addition to the pump motor M which is already in operation for putting the hydraulic system into a condition of readiness (time t
  • the time relay 49 energizes the solenoid 14 at the time t by closing a switch 50, whereby the reversing valve 8 is set for lifting and a voltage is supplied to the solenoid 51 of the high speed valve 32 through the conductor 52 for opening the valve.
  • the switch is closed, and the stop valve 26 is closed by means of the solenoid 25.
  • the time relay 53 opens the circuit and the stop valve 26 is opened by spring pressure.
  • the ring rail 2 again rises rapidly until it actuates a switch 54 arranged at a certain elevation, and this establishes connection with a bus-bar 55 for normal operation through the magnet 45 of the sequence switch 47. No more energy is now supplied to the solenoid 51 of the high speed valve 32, and the ring rail continues its ascent at normal speed until it reaches the limit switch 16 and closes it and sets the reversing Valve 8 to descent until it reaches the lower limit switch 17. From then on, it moves up and down, reversed in direction alternately by the limit switches 16 and 17 the elevation of which is adjusted 'by the program motors M and M through the cams 18 and 19, depending on the desired type of winding. When the counting element 44 has run down, i.e.
  • the ring rail continues on its movement until it reaches the upper has been switched to the end bulge bus-bar 58, the supply of energy to the motors M M and M is also cut oif, so that the spindles of the machine are brought -to a standstill at the time t This, however, still enables a sufficient number of turns to be wound on to the tip of the sleeve 34 to form the end bulge 36 after the mechanical stop OMA has been reached and before the spindle is brought to a complete standstill.
  • the program of movement shown in FIGURE 3 differs from the one shown in FIGURE 2 by the fact that the end bulge is formed at the bottom in the region of the waste bulge 38. This means that instead of the ring tr-ail being raised to the upper mechanical stop OMA after the time t it is lowered to the lower stop UMA.
  • the circuit diagram is altered accordingly, as shown in FIG- URE 7.
  • the ascending ring rail 2 actuates the switch 54 which activates the end bulge bus bar 58 through the sequence switch 47 and thereby reverses the ring rail movement through the conductor 64.
  • the time relay 60 begins to operate and at the time t it switches on to high speed through the switch 63.
  • the switch 54 is actuated whenever it is passed by the element 23, but is effective only when there is current in the starting bus-bar 48 or in the end bulge'busbar 58.
  • the switch 54 becomes effective when, after starting, the quick ascent of the ring rail changes to normal winding operation and when, after actuation of the switch 57 by the counter 44, the normal winding program changes to end bulge formation.
  • the switch 54 must be so placed as to be always below the lowest position of the switch 16 because, otherwise, the normal winding program cannot be changed to the end bulge forming program.
