Definitions

  • the present invention relates to a control and switching device for hydraulically driven traverse mechanisms in spinning, spooling and, in particular, ring twist machines. More particularly, the subject invention relates to control and switching devices in which the directional change of the traverse stroke is caused by electrical end switches and wherein the movements of the working piston of the traverse drive temporarily undergo an acceleration as the amount of pressure fluid supplied to or led oii from the working cylinder per time unit is altered.
  • the present invention therefore, has as its basic objective the bringing about of speed changes of the stroke movement in hydraulically driven traverse systems hydraulically, but without such templates, cam parts or other mechanical control means and without the drawbacks inherent in these.
  • the present invention is based on the insight that for a traverse stroke of constant velocity there is required for the moving of the working piston a certain amount of pressure fluid likewise remaining constant in the time unit, and that for the increase of the speed of the working piston there is necessary in each case a certain additional amount of pressure fluid per time unit, which, however, should be Variable within wide limits for the great variety of possible traverse programs.
  • the control and switching device in such a way that in the feed and drain system of the hydraulic working circuit between the pump with its appropriate path valve on the one hand and the two Working cylinder sides on the other hand there is switched parallel to the adjustable quantity regulators allocated to each of these sides an additional feed and drain line each with a controllable choke member or a choke member in common.
  • the choke member or members can be made controllable by means of a hydraulic dosing device, tor example,'a measuring pump, an auxiliary amount regulator, an auxiliary choke member, or the like, which is preferably arranged in the return flow of the hydraulic control circuit of the choke member.
  • this control circuit there can be provided, preferably, an electromagnetically operated control valve as, for example, a simple reversing slide.
  • Such an arrangement makes it possible for the adjusting of the basic speed necessary in each case of the traverse movement by means of quantity regulators arranged in known manner in the feed and/or drain line system of the working cylinder to use simple chokes, slide valves, and the like as quantity regulators.
  • the traverse speed can be altered at will by control of the flowthrough amount in the additional feed and/or drain lines engaged, according to the invention, parallel to the usual conduction system, by the method that the choke member provided in these lines, adjustable and possibly in common, is controlled, for example, in dependence on the working piston movement or according to a desired program.
  • the choke member may be executed as control slide valve, quantity regulator, or the like.
  • the control of the choke member takes place preferably over a hydraulic dosing device as well as an ordinary electromagnetic control valve which is operated by electric switching impulses in dependence on the time or, over limit switches, by the traverse program.
  • an especially driven impulse generator or else the already present electric limit switches which cause the direction change of the traverse stroke can be used, indirectly or directly.
  • one or several adjustable control switches may be allocated as impulse-givers for the choke member or choke members to the limit switches for the directional change of the traverse stroke, and this adjustable control switch or these adjustable control switches may be movable, if desired, directly or indirectly through the conveyor members which shift the limit switches for the directional change of the traverse stroke.
  • the throughput capacity of the choke member engaged, according to the invention, parallel to the quantity regulator is fully utilized for the control of the traverse speed.
  • the control intensity is here considerably more sensitive and precise than in those quantity regulator systems in which only a fraction of the throughput is controlled.
  • the hydraulic displacement of the choke member in a hydraulically driven traverse system does not present, say, only a constructively more expedient and less space-consuming solution, but actually brings about, in contrast to the known rigid mechanical control mechanisms, the realization of the demand to make it possible in a simple manner during the course of the program to make corrections and to carry out any variations that may subsequently still be necessary in the winding structure. It is precisely this, however, which is decisive in practical use.
  • control and switching apparatus operates entirely automatically according to a program settable at will, it nevertheless frequently occurs, for example, after a change in the winding form or type of distribution or in the material: or denier, that it is necessary during running operation to modify the course of the program, and to make corrections which may possibly be necessary by hand. This is now possible in a simple manner with the aid of the device according to the invention.

  • FIGURE 2 shows the modified arrangement of the electric control and limit switch
  • FIGURE 3 shows a form of the choke member in the hydraulic control system.
  • the hydraulically driven traverse mechanism consists essentially of the ring rail 1, which is suspended on draw bands 2, which, in turn, are secured over deflection rollers 3 continuously with their other end on the piston rod 4 of the working piston 6, admitted on both sides, conducted in the hydraulic cylinder 5.
  • the switching feeler 7 On the piston rod 4 there is mounted the switching feeler 7, Which operates the limit switches 8, 9 for the release of the stroke reversal and also special control switches 10, 11 as impulse generators for the control of the traverse speed, in which arrangement the switches are shifted by the threaded spindles 12, 13, acting as conveying members, of, for example, electrically controlled program adjusting system 14.
  • Such a program adjusting system is described in detail in application Ser. No. 374,109 which was filed on June 10, 1964, the disclosure of which is incorporated herein by reference.
  • the hydraulic working circuit of the traverse system consists of the pump 15 which conveys the pressure fluid from the supply tank 16 over the line 17 to the electromagnetically operated path valve 18.
  • a manometer 2i To the line 19 branching from line 17 there are connected a manometer 2i and a pressure limiting valve 21 for the measurement and setting of the pressure prevailing in the hydraulic system.
  • the switched-in zero position 22 of the path valve 18 is represented.
  • the other switching positions are numbered 23 and 24.
  • the lines 26-27 of the working circuit connect valve 18 with the two passages of adjustable choke member 28, which is represented in a special form of execution in FIG. 3 and is described in further detail below.
  • the left-hand passage of the choke member 28 is connected through line 33 to line 32.
  • Line 34 is connected to line 27 and leads over the permanently adjustable quantity regulator 35 or the nonreturn valve 36 arranged parallel to regulator 35 and the line 37 into the right-hand side of the working cylinder 5.
  • Line 37 and the right-hand passage of the choke member 28 are connected with one another by line 38. From line 17 there branches off the control line 39 for the choke member 28 and leads into the valve 40 with its switching positions 41 and 42.
  • valve the control line 43 leads into the left-hand side of choke member 28, while the right-hand side of choke member 28 is connected through the control line 44 with the control valve 40. From valve 40 the control line leads over the dosing device 45, for example, a settable and adjustable auxiliary quantity regulator, back into supply tank 16.
  • dosing device 45 for example, a settable and adjustable auxiliary quantity regulator
  • FIG. 2 there is shown a modified arrangement of the control and end switches.
  • the limit switches 8 and 9 mounted on the spindles and conveyed through these carry sheet metal strips 46 and 47 with long holes 48 and 49, through which there are inserted screws 50 and 51, by means of which the control switches 10 and 11 are secured to sheet metal strips 46 and 47.
  • the spacing between the limit switch 8 (or 9) and the control switch 10 (or 11) can be adjusted very easily and rapidly, while in the arrangement according to FIG. 1 it is first necessary to release a guide (not shown).
  • FIG. 3 finally, shows the aforementioned choke member 28 in a special form.
  • the control piston which consists essentially of three individual pistons 55, 56, 57 mounted at a distance from one another, which are solidly joined with one another by intermediate pieces 58, 59 of piston rod type.
  • covers 52 and 53 there are provided central bores 66, 61 for connection to the control lines 43, 44 (FIG. 1).
  • the ring-shaped cylinder chambers 62, 63, 64, 65 each have a connecting bore 66, 6'7, 68, 69 leading through the cylinder casing wall for the pressure fluid lines, 26, 27, 33, 38 of the hydraulic working circuit.
  • profiled grooves or notches 72, 73 in the right-hand annular end surface 70, 71 of the individual pistons 55, 56 which form the connecting channels between the paired annular cylindrical chamber 62/63 or 64/65.
  • FIG. 1 of the individual hydraulic switching and control elements are only schematically shown and are not intended to characterize any particular situation in the course of a given working program.
  • a winding form with an approximately cylindrical middle portion and curved conical ends, the form and pitch of which is to be different.
  • This winding form is caused by the fact that the relatively great traverse stroke of the ring rail, in relation to the total winding length, remains equal over the entire winding process and, from one end of the spool to the other, is slowly displaced during the entire winding process. In the process, the individual stroke has to be accelerated toward its ends.
  • Means are provided for the formation of a thread reserve before the start of the winding process proper by means of individual or collective lowering of the spinning or twisting rings (not shown or described).
  • the threaded spindles 12 and 13 have thread rising to the right and turn, according to the winding program here selected as an example, at equal turning speed and like direction, so that the limit switches 8 and 9 and also the control switches 16 and 11 move from right to left with constant spacing, until one of them is operated by a blocking switch (not shown) for the termination of the winding program.
  • the degree of opening speed of choke member 28 depends on the setting of the auxiliary quantity regulator 45, through which the pressure fluid emerging from connection bore 60 of the left-hand chamber of choke member 28 flows over line 43 and control valve 40 (switching position 42) back into supply tank 16.
  • auxiliary quantity regulator 45 determines the speed at which the passage cross sections of adjustable choke member 28 are opened and closed, and thereby the degree and the course of the acceleration and retardation of the movement of working piston 6 and ring rail 1.
  • the carried-along switching feeler '7 runs over, in the back and forth passage, the control switches 10 and 11, and, namely, in each case immediately before the stroke reversal, for the purpose of the start of the acceleration, and immediately after the stroke reversal for the switching on of the functional readiness of the other control switch without further control function of its own.
  • the proposed apparatus has the important advantage that any detectable deviations occuring during the winding process of the desired winding form can immediately be corrected by readjustment of auxiliary quantity regulator 45 and/ or of control switches 10 and 11.
  • the control cams or plates under these circumstances must be dismantled and interchanged in a complicated manner, or reworked or even completely remade and, moveover, the reject loss through faulty control in the imperfect yarn windings has to be accepted into the bargain.
