Definitions

  • a control valve device permits of adjusting the flow rate through said discharge conduit and therefore of determining through said hydraulic motor the displacements of said ring rail.
  • the present invention relates to spinning machines, and in particular to spinning frames, twisting frames, etc., and more especially to those where the textile yarn is wound in conical layers, such spinning machines including a ring rail the vertical reciprocating movement of which is hydraulically controlled.
  • Such a hydraulic control device had the following drawbacks, due to the reversals in the direction of flow through the control distributing valve when the movement of the ring rail is to be reversed:
  • the object of the present invention is to eliminate these drawbacks.
  • the machine with which this invention is concerned comprises, in order to provide for the upward movements of the ring rail, at least one single acting volume variation responsive hydraulic motor fed with transmission liquid from a continuous action hydraulic pump.
  • this machine comprises, on the one hand, a discharge conduit connected with the delivery of said pump and having a cross-section permitting a flow rate therethrough higher than the delivery flow rate of the pump, and, on the other hand, a control valve device mounted in said discharge conduit and adapted to control the liquid fiow rate through said discharge con duit and, therefore, the flow rate to or from said hydraulic motor, whereby said valve device, while permitting a controlled feed to, or discharge from, the hydraulic motor, is flown by a liquid stream the flow rate of which depends upon the position of this valve device but the direction of which is always the same.
  • FIG. 1 is a diagrammatic view illustrating the formation of cops in a spinning machine according to this invention
  • FIG. 2 is a diagrammatic perspective view of the essential elements of the ring rail hydraulic control device of such a machine
  • FIGS. 3 to 7 inclusive diagrammatically show said control device in five different positions of the parts thereof.
  • a quick upward movement M brings the ring rail substantially to a position at mid-height of its total stroke, this upward movement being adapted to stretch the yarns from the feed devices.
  • This upward movement is followed by a quick downward movement M stretching the yarns and bringing the ring rail into the region (for instance at a level P slightly above the lowermost level PMB) where is to be performed the formation of the rounded base of the cops.
  • the ring rail is then given a succession of upward and downward movements M, with a vertical offsetting between two successive movements in order to form the cops by conical layers.
  • the ring rail is given a quick upward movement M, of small amplitude in order to permit the winding at a constant height, of some turns of the yarn forming a reserve at the upper end of the cop.
  • the machine comprises spindles 2 actuated by a shaft 3 driven by the main motor 4.
  • Driving shaft 3 further drives delivery cylinders 5 for feeding the material to be spun to spindles 2, through a suitable positive transmission system the elements of which are designated by the same reference numeral 6.
  • a ring rail 7 mounted in vertical guides (not shown) and connected, through belts 8, to one end of a common pulling belt 9 the other end of which is fixed to a drum carried by a shaft 11 hereinafter called ring rail control shaft.
  • the control means intended to impart upward and downward displacements to ring rail 7 must be arranged to permit of giving shaft 16 movements away from control shaft 11 (upward movement of the ring rail), the movements towards said shaft 11 (downward displacement of ring rail 7) then taking place at least chiefly under the effect of the weight of ring rail 7.
  • Said control means are of the hydraulic type and include a single acting volume variation responsive hydraulic motor 17, the cylinder of which is at right angles to shaft 16.
  • the fixed cylinder of said hydraulic motor 17 advantageously constitutes the support of the anchoring points 13 of pulling belts 12 and the movable portion of said motor consists of a piston 17a and a piston rod 17b secured to said shaft 16 as shown by FIG. 3.
  • discharge conduit 22 connected with the delivery conduit 23 of hydraulic pump 20, is given a cross-section permitting a liquid flow rate therethrough higher than the delivery flow rate of pump 20 and there is provided, in said discharge conduit 22, a control valve 24 for adjusting the flow rate of the liquid passing through discharge conduit 22.
  • piston 17a of hydraulic motor 17 is in balanced position for a given degree of opening of the active element of control valve device 24, that said piston 17a will be pushed upwardly by liquid under pressure fed through conduit 18 for smaller degrees of opening of control Valve device 24 and that, on the contrary, for greater degrees of opening of valve device 24, piston 17a will be moved downwardly by the effect of gravity and cause liquid to be discharged through conduit 18.
  • valve device 24 permits, not only of reversing the direction of displacement of piston 17a (and of ring rail 7) but also of adjusting the speed of the upward and downward movements of the ring rail, the upward movement of said ring rail being the faster as valve device 24 is nearer to its maximum closing position, and the downward movements of said ring rail being the faster as said valve device 24 is nearer to its fully opened position.
  • Valve device 24 is advantageously controlled so that the movable part 24:: of valve 24 is actuated by a mechanism responsive to the difference that may exist between the actual position of ring rail 7 and the theoretical position where said ring rail should be located at the time that is considered so as to comply with the law of formation of the cops that is imposed. Such a difference actuates said movablep art 24a of valve device 24 in such manner as to reduce to zero the difference between the actual position and the theoretical position of the ring rail.
  • valve device 24 will behave as follows:
  • Movable part 24a will be moved in the direction opening the communication controlled by valve device 24 if the actual position of ring rail 7 is above its theoretical position.
  • Said part 24a will be moved in the direction closing the communication controlled by valve device 24 if the actual position of ring rail 7 is below its theoretical position.
  • control device is made as follows:
  • valve device 24 The movable part 24a of valve device 24 is subjected to the action of a spring 25 urging said movable part 24a in the direction Where it opens more and more the cross-section of the passage through said valve device 24.
  • Said movable part 24a is connected to the axis of a return pulley 26 around which passes a belt 27a27b.
  • Belt portion 27a is subjected to the action of first mechanical pulling means capable of producing a translatory movement of belt portions 27a and 27b of an amplitude corresponding to the theoretical position that should be occupied by ring rail 7.
  • Belt portion 27b is subjected to the action of second mechanical pulling means capable of producing a translatory displacement of belt portions 27a and 27b in a direction opposed to the preceding one and with an amplitude corresponding to the actual position of ring rail 7.
  • Said first and second pulling means are therefore arranged in such manner that, when the actual position of ring rail 7 coincides with its theoretical position, both of the translatory displacements imparted to belt portions 27a and 27b by said first and second mechanical pulling means are equal in absolute value but of opposed directions and therefore neutralize each other, whereby the axis of return pulley 26 remains stationary.
  • any difference (either positive or negative) between said theoretical and actual positions produces a variation of the total length of belt portions 27a and 27b and causes a displacement of the axis of pulley 26 and of said movable part 2411 until the difference is compensated for.
  • the second mechanical pulling means responsive to the actual position of ring rail 7 for controlling belt 27a- 27b comprise a drum 32 to which is fixed the end of belt portion 27b, said drum being fixed on the shaft 11 which drives ring rail 7.
  • the first mechanical pulling means responsive to the theoretical position of ring rail 7 for controlling belt 27a-27b comprise a cam 37 which cooperates With the frame 34 of a belt stretching device in which is journalled a pulley 33 around which belt portion 27b passes, between return pulley 26 and drum 32.
  • Said belt stretching device frame 34 is subjected to the action of a spring 35 bearing against a fixed abutment 36 (the strength of said spring 35 being greater than that of spring 25).
  • the free end of belt portion 27a is secured to the peripher of a drum 28 driven in rotation at reduced speed (through a friction clutch not illustrated by the drawings) by transmission system 6 connected with the yarn delivery cylinders 5, this drum 28 materializing the vertical successive movements to be imparted to ring rail 7 to ensure the formation of superposed conical layers of yarn on the cops.
  • Drum 28 is driven from transmission system 6 through a worm 29 and a worm wheel 30 and a gearing down device 31.
  • Cam 37 is driven from the means 6 for driving delivery cylinders 5 through transmission gears 38 driven from the shaft for driving drum 28.
  • control valve 24 includes a fixed casing and a movable part 24a in the form of a piston. Said piston 24a leaves constantly open an orifice 24b communicating with the portion of discharge conduit 22 located upstream of valve device 24. Piston 24a controls an orifice 24c communicating with the portion of discharge conduit 22 located downstream of valve device 24.
  • Such a control device has the advantage of easily accommodating itself to the use of blocking or short-circuiting apparatus which permit of obtaining quick upward or downward displacements of the ring rail.
  • a hydraulic motor 39 capable, when it is placed under pressure, of releasing a brake 1 (FIG. 2) capable of stopping the machine when liquid pressure is applied to hydraulic motor 39.
  • the hydraulic control system above described may further include the following auxiliary apparatus shown by FIGS. 3 to 7, which are intended to permit of producing cops as indicated diagrammatically by FIG. 1.
  • Said auxiliary apparatus are the following ones:
  • a two-way electromagnetic valve 40 inserted in discharge conduit 22 between the feed conduit 18 of hydraulic motor 17 and valve device 24, said valve 40 being adapted, when not energized, to stop discharge conduit 22 and, on the contrary, when energized, to open said conduit 22;
  • a two-way electromagnetic valve 41 inserted in a conduit 42 extending between the delivery conduit 23 of pump 20 and the portion of discharge conduit 22 located downstream of valve device 24, said valve 41 being arranged, when energized, to open conduit 42 and, when not energized, to stop this conduit 42;
  • a three-way electromagnetic valve 43 adapted to place the feed conduit 44 of brake control hydraulic motor 39 in communication either, when said valve 43 is energized, with the pump delivery conduit 23 through a check valve 45, or when said valve 43 is not energized, with a discharge conduit 44a through which hydraulic motor 39 can discharge its liquid into tank 21;
  • a discharge valve 46 inserted in a conduit 47 extending between the delivery conduit 23 of pump 20 and discharge conduit 22, said valve 46 being adjusted to open in case of overpressure in the delivery of said pump;

  • Valve 43 is still energized.
  • Valve 40 is energized so that discharge conduit 22- and valve device 24 are opened.
  • Valve 41 is not energized.

  • FIG. 5 corresponds to the movement M of FIG. 1, through which the cops are formed with identical conical layers, the main motor 4 having started at the beginning of movement M
  • This phase corresponds to the formation of the cops, valves 40 and 43 being energized whereas valve 41 is not energized.
  • Valve device 24 ensures at any time a correct height of ring rail 7.
  • FIG. 6 corresponds to the movement M; of FIG. 1.
  • Valve 43 is still energized.
  • Valve 40 is no longer energized so that discharge conduit 22 is stopped.
  • Valve 41 is not energized so that conduit 42 is stopped.
  • hydraulic motor 17 receives the whole of the liquid delivered by pump 20 and, when the ring rail reaches its top position, discharge valve 46 opens, thus permitting the winding at constant height of the portions of the yarn that are to form the reserve of the cops during the end of movement M
  • FIG. 7 corresponds to the movement M of FIG. 1.
  • Valve 43 is still energized.
  • Valve 40 is not energized.
  • valve 41 is energized so as to permit the flow of liquid through conduit 22 and a quick discharge of the liquid from hydraulic motor 17.
