Definitions

  • the present invention relates to a textile machine comprising spindles and strand-guides positively driven by shafts having a controlled differential rotation, the spindles and strand-guides being displaceable in relation to one another due to a up-and-down device.
  • the machine eventually comprises at least one delivery cylinder which, as the case may be, forms part of a drawing frame.
  • the terms spindles and strand-guide must not be taken too literally and should be extended in meaning to include equivalent elements on various textile machines.
  • the drives consist of One or several motors and mechanical transmission means such as gears, chains, cams, belts, etc. providing predetermined ratios between the various movable parts of the machine.
  • gears chains, cams, belts, etc.
  • the ordering signals are electrical, the central coordinating means being an electronic device.
  • This electronic device receives the spinning data and the parameters particular to the operation to be carried out (geometry of the bobbin), the data being introduced either manually, either previously prepared and stored on a support such as perforated cards or strips, magnetic tape, etc. creating speed and position ordering signals for the various components in the form of elec-
  • the advantage of this arrangement is that it is completely 3 static and quite rapid.
  • the individual driving devices driving the movable components of the machine are hydraulic motors combined with control devices responsive to the independent control chain signals, the hydraulic motors being preferably fed by a hydraulic generator group.
  • FIG. 1 is a diagram of the driving and control devices of the textile machine according to the invention.
  • FIGS. 2 and 3 are cross-sectional views of special form bobbins.
  • the invention is applicable to textile machines such as spinning looms, twisting mills, pre-spinning machines, such as those called roving frames etc. These machines comprise a great number of spindles mounted on a roving frame 1 and strand-guides on a strand-guide frame 2.
  • the spindles are brought into rotation by means of a shaft 3 and the strand-guides by means of a shaft 4.
  • the speed of the spindles differ from that of the strand-guides by a diiferential speed, shafts 3 and 4 being interconnected by gearing means 5 and 6 and by a differential 7 having a crown the rotation of which is controlled by a shaft 8.
  • the roving frame 1 as well as shaft 3 and gearing 6 are supported by two jacks 9 and 10
  • the textile machine may further comprise a delivering cylinder and one or several drawing cylinders.
  • the driving shafts for the delivering cylinder and the feeding cylinder are numbered 11 and 12, respectively.
  • An intermediate cylinder could be provided to serve as a predrawing cylinder.
  • hydraulic motors energized by a hydraulic generator group The latter is formed by an electric cage motor driving a pump 14, a fly wheel 15 and a pump 16 connected to motor 13 by rigid couplings.
  • Pumps 14 and 16 have a variable cylinder displacement.
  • Pump 14 is provided with a device 17 for the adjustment of the cylinder displacement, the device being operated by remote control through the medium of a synchronous receiver 18.
  • Pump 16 has a device 19 for adjusting the cylinder displacement, device 19 being actuated by another device 20 sensitive to the outlet pressure of pump 16 and automatically maintaining the pressure at the outlet of pump 16 constant regardless of its flow.
  • Pumps 14 and 16 are fed by a motor fluid collecting into a discharge reservoir 21.
  • the motor fluid flows through a heat exchanger 22.
  • Pumps 14- and 16 as well as their regulating and driving equipment are located in an engine room and are connected by means of piping to the motors of the machine in the spinning room. This separation between generator and motors is illustrated in the drawing by a dash line Z-Z, separating the parts of the textile machine which are located in the spinning room from those located in the engine room.
  • Pump 14 is mounted in parallel on two hydraulic motors 23 and 24 respectively driving shafts 3 and 4. Adjustment of their speed is obtained by adjustment on the cylinder displacement of pump 14, directed by means of a control on the control console, for instance a synchonous generator 25 connected to a synchronous receiver 18.
  • This basic speed is .set at a desired value by acting on the cylinder displacement of pump 14 by means of a synchronous generator 25 on the console.
  • the speed of shaft 4 is measured by a speedometer 26, the measure voltage of which is fed into a central coordinating member, in this particular instance an electronic set 27, segregated in the drawing by a dash line contour.
  • This electronic set is formed by various computing devices, among others, integration devices which also act as memory device; within these computing devices, certain parameters are capable of being regulated.
  • the electronic set sends out position and speed ordering signals for the various movable parts of the machine.
  • the measure voltage delivered by the speedometer 26 is a signal proportional to the speed of the strand-guides.
  • This signal is modified according to the twisting rate foreseen in a device 28 which, in the case where the speed of the strand-guide is proportional to the delivery speed, may be a potentiometer.
  • a signal 29 appears at the output of device 28, the said signal being an image of the linear winding-on speed necessary to obtain the twisting rate 3 desired. This signal, image of the linear winding-on speed,
  • a signal 31 appears at the output of device 30 which serves as an order for controlling the delivery speed necessary to obtain a desired drawing under twisting.
  • Signal 31 an order for the delivery speed, is compared in a comparison device 32 with the signal coming out of the speedometer 33 measuring the speed of shaft 11, driven by a motor 34, connected to the constant pressure of pump 16 through a servo-valve 35.
  • the control chain for the control of the delivering cylinder driven by shaft 11 is thus formed by the comparison device 32 sensitive to the order signal 31, servo-valve 35, motor 34 and speedometer 33.
  • the comparison device 32 delivers an error signal obtained by substracting from the order signal 31 a measure signal 36 appearing at the output of the speedometer 33.
  • the control of servo-valve 35 is a function of this error signal.
  • Signal 36 coming out of speedometer 33 is an image of the actual delivery speed. It is modified according to the drawing rate to be expected at the cylinders by means of a device 37, in this instance a potentiometer. At the outlet of this device 37, there appears a signal 38, which is an order for the feeding speed to be foreseen.
  • the feeding cylinder, connected to shaft 12, is driven by a motor 39 joined to the constant pressure of pump 16 through a servo-valve 40.
  • the control chain for the control of the speed of the feeding cylinder, driven by shaft 12, is thus formed of a comparison element 41 sensitive to order signal 38, servo-valve 40, motor 39 and a speedometer 42.
  • Signal 29 an image of the linear winding-on speed, is also applied to a control means made up by a computer comprising a function integrator-generator assembly 43, preceded or followed by a multiplicator 44 which makes it possible to take into account the direction of displacement of the up-and-down and of the winding pitch.
  • a signal 45 appears at the output of the assembly of devices 43 and 44, signal 45 taking into account the length of wound thread and of the law of formation of a bobbin layer.
  • the function generator in device 43 is conceived in such a manner that signal 45 gives the position of the thread in relation to the start of the layer being formed.
  • a device 46 for the detecting of the limit height of the layers can send out a commutation signal 47 toward device 44, in such a way that the signal (Winding direction upwardly or downwardly) and the value (magnitude of the winding pitch) of the multiplier introduced by device 44 may be accordingly modified.
  • Commutation signal 47 serves, on the other hand, as counting impulse and consequently. feeds also an integrator 48 of the number of layers.
  • signal 45 is an image of the cyclic variations of the instantaneous position of the thread as it is being wound in relation to the beginning of the layer.
  • Signal 45 thus serves as an order signal for the movement of the up-and-down device.
  • signal 45 is introduced in two comparison devices 49 and 50 respectively receiving the output signals of two position measuring devices 51. and 52 of two jacks 9 and 10 of the up-and-down device.
  • Jack 9 is actuated from pump 16, through servo-valve 53 controlled by comparison device 49.
  • Jack 10 is actuated from, pump 16 through servo-valve 54 controlled bycomparison device 50.
  • the integrator 48 of the number of layers delivers an output signal 55 proportional to the state of loading of the bobbin during the formation thereof, signal 45 making it possible, on the one hand, to modify certain adjustments in relation to the increase in the number of layers, for instance, the adjustment relative to the geometry of the bobbin, and on the other hand, to cause certain operations such as stopping of the machine at the time when a predetermined number of layers is reached.
  • signal 55 is added to signal 45in a device 65 in such a manner that a progressive spacing between the roving frame and the strand-guide frame is obtained at the same time as the cyclic movement of th' up-and-down movement.
  • bobbins it is also possible to vary the up-and-down cycling movement, for instance by sending signal 55 backto a device 56, changing the height limits of the layers, as defined by detector 46.
  • a measure makes possible, for instance, the formation of bobbins according to FIG. 2.
  • a spindle 70 supports conical layers 71, of different height.
  • FIG. 3 Another example of formation of bobbins is illustrated in FIG. 3.
  • the spindle 72 supports layers 73 which are either cylindrical or have a small conicity and of different height.
  • the differential rotation between spindles and strandguides is controlled also by the central member of coordination.
  • the crown of differential 7 is driven by an individual motor 57 through shaft 8.
  • the independent control chain controlling the motor 57 is constituted by a comparison device 58, a servo-valve 59 and a measuring device, for instance, a speed measuring device 60.
  • the signal 45 may advantageously be used.
  • a function generator for instance, an assembly 61 of an integrator and a multiplicator device may be mounted betweenthe measuring device 60 and the comparison device 58.
  • the integrator in device 61 allows transformation of the speed signal into an angle measuring signal.
  • the latter is proportional, to a winding pitch, to the instantaneous position of the thread being wound.
  • the factor due to the winding pitch is introduced by adjustment means provided in device 61 and modified in relation to the commutation signal 47.
  • the output signal 62 is also an image of the cyclic variations of the instantaneous position of the thread as it is being wound in relation to the beginning of the layer being formed, as is signal 45.
  • the comparison of these two signals 62 and 45 in device 58, results in an error signal 63 serving to control the servo-valve 54.
  • an auxiliary modifying device 64 makes it possible to add an anticipation signal to order signal 45, for instance, a signal proportional to the derivative of the order signal 45. This makes it possible to compensate for the lagging effect which appears at high rotation speeds. This lagging effect is due to the fact that the thread does not follow a horizontal line between the strand-guide and the bobbin being formed but, rises towards the point of the bobbin when the spindles rise and fall towards the base of the bobbin when the spindles dip.
  • a measuring device 66 delivers a signal 67 particularly capable of controlling the stopping of the machine.
  • a spinning machine having spindles, rotatable guides moving around a bobbin and laying a thread thereon, a shaft driving the spindles, a shaft driving the thread guides, raising and lowering devices displacing the thread guides relative to the spindles, a differential connecting the shaft driving the spindles to the shaft driving the thread guides, feed and delivery rollers, driving devices for driving the shafts of the raising and lowering devices, the differential, the feed and delivery rollers, control devices for said driving devices, and an electronic controller fed with data and signals derived from one or more of the moving parts of the equipment whereby the driving mechanism is controlled by information fed to the electronic controller, the improvement wherein, said electronic controller comprises:
  • an integrator connected to said detector and sup plying control pulses when the height limit of a layer has been attained; said integrator supplying an output signal proportional to the number of layers of threadwound on the bobbin during the formation thereof;
  • (11) a device permitting the modification of the height limit of the layers defined by said detector and connected to and fed by said output signal of said integrator;
  • a function generator connected to a velocity measuring device located on said shaft driving a differential crown wheel between said drives of said guide and said spindle; said function generator and said functional integrator-generator device also being connected to said control device of said driving device of the shaft of said crown wheel;
  • a spinning machine comprising:
