Definitions

  • the invention relates to automatic winding control means in continuous ring spinning frames and the like, for example, continuous twisting frames.
  • the ring-carrying rails In forming wound bobbins, the ring-carrying rails have imparted to them an up and down movement of constant amplitude permitting the winding of the thread in truncated layers; this movement is called periodic movement.
  • the length of the thread wound during one run of the ring-carrying rails is called a needleful. After each needleful, the ring-carrying rails are displaced upwards relative to their middle position to permit the Staggering of the layers of threads; this movement is called fundamental movement.
  • the combination of these two movements constitutes the actual winding movement of the spinning frame.
  • the invention has, as an object, the provision of means adapted to effect the automatic carrying out of one, at least, of these two phases of overwinding and underwindmg.
  • the winding control device that is to say, control of the up and down movements of the ring-carrying rails of the frame, comprises, on the one hand, a driving member capable of being operated by an alternating movement and constituting an element of a first differential and, on the other 3,521,327 Patented July 28, 1970 hand, a driven member permanently connected to the rails and constituting an element of a second differential, the two differentials having a common element, a further element of the first differential being connected to a ratchet wheel in engagement with a pawl carried by the driving member while the further element of the second differential may be either held fixed or be driven in one direction to ensure the overwinding, or in the other direction to ensure the underwinding, while an element pivoting coaxially with the ratchet wheel carries a second pawl co-operating with this ratchet wheel and a fixed stop limits the pivoting amplitude of the pivoting element in the direction of ascent of the rails to cause an advance of the
  • the invention likewise relates to forms of construction comprising one, at least, of the following features:
  • the first differential comprises an intermediate gear in simultaneous engagement with the planetary gears and with the pinion integral with the ratchet wheel so as to ensure a rotation of the planetary gears and the pinion in the same direction.
  • FIG. 1 is a profile view of the ring carrying rails in a winding control mechanism according to the invention
  • FIG. 2 is a plan view, partly in section, of portions of the winding control mechanism of FIG. 1;
  • FIG. 3 shows a detail of FIG. 1
  • FIG. 4 is a profile view of the winding mechanism with the ring carrier rails in a raised position
  • FIG. 5 shows a frame spindle carrying a finished bobbin.
  • FIG. 1 can be seen a part only of a continuous ring spinning frame 1 carried by a rail 2 fixed on the upper end of small pillars 3 mounted to slide vertically in guides 7, 8 of the frame 9.
  • the ascending and descending movement of the ring carrying rails 2 is effected by a horizontal rod 12 to which is attached one end of a belt 13 which passes over an idler roller 17 with a horizontal axle and the other end of which is attached at 18 to the lower end of the corresponding pillar 3.
  • the rod 12 is mounted so as to be capable of being operatedwith a horizontal toand-fro movement in the frame 9 of the machine, under the action of a winding control means 21.
  • a finished bobbin of thread mounted on a vertical rotating spindle 25 (see also FIG. 5) which is driven in conventional manner by a strap or belt (not shown) passing over a pulley 28 secured to the said, spindle.
  • the winding control device 21 comprises a rotating horizontal shaft 31 (see also FIG. 2) supported by the bearings 32, 33 mounted on two supports 34, 35 secured to the frame 9 of the machine.
  • a part 47 having three arms, and which will be called hereinafter a star, is fixed to the shaft 31, for example, by keying.
  • a ring 54 pinned to the other end of the shaft 31 to hold the assembly of adjacent parts axially on the shaft.
  • a gear 61 In engagement with the pinion 42 is a gear 61 (see also FIG. 3) integral with a pinion 62 loosely mounted for rotation on an axle 63 fixed in the plate 44 parallel to the shaft 31.
  • the pinion 62 is in engagement with a gear 64 secured to one end of a shaft 65 rotatably mounted in the plate 44, likewise parallel to the shaft 31.
  • a pinion 66 On the other end of the shaft 65 is fixed a pinion 66 which is in engagement with the gear 45 loosely mounted on the shaft 31.
  • Planetary pinions or gears 64 and 66 constitute satellite elements of the second differential.
  • the plate wheel gear 43 is in engagement with a pinion 7.1 secured to one end of an axle 72 rotatably mounted in an arm of the star 47 and lying parallel to the shaft 31.
  • a gear 73 which is in engagement with a gear 74 loosely mounted on an axle 75 fixed in the star 47 and likewise parallel to the shaft 31.
  • the gear 74 is also in engagement with the central pinion 49.
  • Planetary pinions or gears 71 and 73 constitute satellite elements of the first difierential.
  • On one arm of the star 47 is fixed an axle 77 which serves as a pivot for a pawl 78 in engagement with the ratchet wheel 48.
  • the star 47 executes, on the shaft 31, an oscillating movement of an amplitude of the order of 50, such that the pawl 78 always remains above the horizontal plane passing through the axle of the ratchet wheel 48; furthermore the shape of the pawl is such that it has on the left hand side (looking'at FIG. 1) a protuberance forming a head so that the pawl 78 is always urged against the ratchet wheel by the action of gravity.
  • W th the ratchet wheel 48 there also co-operates, likewise under the action of gravity, a pawl 81 mounted on a pivot 82 carried by the oscillatory lever 53.
  • the direction of inclination of the teeth of the ratchet wheel 48 is that shown on the drawing, that is to say, such that each of the two aforementioned pawls opposes clockwise rotary movement of the ratchet wheel relative to the members which carry the pawls.
  • Pivoting movement of the oscillatory lever 53 in the direction of rotation to the right is limited by a corner piece of a stop 85 which can be secured by means of a bolt 86, in any desired position of adjustment along a guide 87 which has an arcuate groove 88 concentric with the shaft 31.
  • a scale 89 enables the position of the corner piece of the stop 85 to be conveniently determined.
  • the guide 87 is fixed on a support 91 secured to the frame 9.
  • Another arm of the star 47 carries a rod 92 parallel to the shaft 31 and adapted to lift the oscillatory lever 53 at a convenient time.
  • the chain 101 passes over a horizontal sheave pulley 102 mounted loose on an axle 103 carried by the frame 9.
  • a chain 106 On the hub of the star 47 is attached one end of a chain 106 the other end of which is attached, preferably in an adjustable manner by a slide 107, to the vicinity of one end of a lever 108 which can oscillate, about its other end, on a horizontal axle 109 carried by a fixed support 111.
  • the lever 108 carries, at an intermediate point of its length, and an axle .114 on which is mounted a roller 115.
  • the roller is pressed, under the influence of the weight of the movable equipment associated with the ring carrying rails acting through the control mechanism 21, against a cam 116 secured to a shaft -117 rotatably driven by means of an electromagnetic clutch 119 from the general control of the machine, which, to simplify the explanation, has been replaced here by an electric motor 1.18.
  • the cam 116 has a positioning cavity 120 in which the roller .115 is located when the rails are in their down position.
  • FIG. 1 there are indicated six switches 121, 122, 123, 124, 125, 126 controlled by corresponding catches 13.1, 132, 133, 134, 135, 136 carried by a carriage 137 fixed relative to control rod 12 of the up and down movement of the ring carrying rails. These six switches are arranged to effect automatic control of the control device of the rod 12 so as to bring about the correct winding with corresponding overwinding and underwinding.
  • the whole of the up and down control mechanism is constituted fundamentally by two differentials.
  • the first differential is constituted by the sun gear 49, the planetary gears or satellite elements 73 and 71 and the second sun gear 43, the satellite carrier being constituted by the star 47.
  • the second differential is constituted by the sun gear 42, the planetary gears or satellite elements 64 and 66 (the pinions 61 and 62 being only intermediary) and the second sun gear 45, the satellite carrier being constituted by the plate wheel 43 which is no other than the second sun gear of the first differential.
  • the plate wheel 43 is therefore an element common to the two differentials.
  • the driving member or star 47 is the satellite carrier of the first differential while the driven member or pulley 46 is a sun gear of the second differential.
  • the pinion 71 in engagement with the plate wheel gear 43 therefore tends to turn to the right.
  • the gear 74 in engagement with the gear 73 therefore tends to turn to the left, and the pinion 49 in engagement with the gear 74 to the right.
  • the ratchet 'wheel 48, integral with the pinion 49 likewise being urged to turn to the right by the star 47.
  • the pawl 78 opposes this movement. This has the result, under the conditions which have just been contemplated, that all the elements carried by the star 47 are locked and form a single body with the latter.
  • the plate wheel 44 has a tendency to turn to the left so that, through its gear 43, it tends to cause the locked pinion 71 to descend and consequently cause the star 47 likewise to pivot to the left which has the effect of tensioning the chain 106.
  • the pinion 71 forming for the moment a solid body with the star 47, drives in rotation the plate wheel 44 and its gear 43, on the shaft 31, in the direction to the right at the same angular speed as the said star.
  • the gear 61 therefore rolls on the pinion 42, now immobile, with the direction of rotation to the right in respect to the plate wheel.
  • the pinion 62 therefore turns to the right, while the gear 64 and the pinion 66 turn to the left. This results in the gear 45 turning on the shaft 31, to the right at a speed a little higher than the angular speed of the plate wheel, but only a little higher, due to the triple reduction ensured by the gear couples 42-61, 62-64 and 66-45.
  • the oscillating lever 53 is driven to the right by means of the pawl 81 and the ratchet wheel 48. A moment comes when, towards the end of the up stroke of the rails, the end of the oscillating lever strikes the stop 85. From this moment the oscillating lever 53 is held immobile in space and is opposed by the ratchet 81 on any continuation of the movement of rotation to the right of the ratchet wheel 48, but the star 47 continues its movement, allowing the pawl 78 to slide on the back of the teeth of the ratchet wheel 48 (FIG. 4).
  • the pinion 49 integral with the ratchet wheel 48 is therefore also held immobile so that the intermediate gear 74 rolls on the pinion 49 turning to the right on the star and causing the gear 73 to turn to the left with respect to the star.
  • the pulley 46 which drives the upward control chain 101 therefore, in respect to the star 47, performs an angular advance corresponding to the number of teeth of the ratchet wheel 48 which have been passed by the pawl 78 of the star while the ratchet wheel has been held immobile by the oscillatory lever 53 stopped by the stop 85.
  • This advance of the plate wheel, with respect to the star, at each up and down cycle ensures the fundamental movement, the amplitude of which may be easily adjusted by a suitable positioning of the stop 85 along the fixed slide 88.
  • an angular unwedging controlled by the pulley 46 to which is attached the chain 101, with respect to the star 47, the angular position of which is determined by the position of the chain 106.
  • the electric motor 98 is turned in one direction or in the other, respectively, and, by means of the chain 95, brings about a corresponding rotation of the gears 41, 42, 61, 62, 64 and 66.
  • the switch 121 puts the automatic control circuit (not shown) under an electric potential but the movement of the rails is not interrupted.
  • the roller When the ring carrying rails reach the lower position B, the roller is located in the cavity of the cam 116; the switch 122 interrupts the periodic movement and controls the starting of the motor brake 98 for the winding.
  • the switch 122 controls also the disengaging of the cam 116 by the release of the clutch 119.
  • the control of the winding spindles is not interrupted during the first phase.
  • the ring carrying rails are brought above the upper level of the stroke, corresponding to the normal winding plate under the action of the motor brake 98 and up to the reserve winding position C (FIG. 5).
  • the switch 123 stops the brake motor and energizes a time relay (not shown) previously regulated to the time required for a predetermined length of overwinding thread.
  • the reserve is formed.
  • the descent of the ring carrying rails is controlled by the time relay which ensures the connection of the brake motor for rotation in the direction to bring about descent of the rails.
  • the carriage 137 operates the switch 124, which controls the energization of the main motor, to bring about application of rotary drive to the spindles 25.
  • the catch 135 operates the switch 125 which controls, on the one hand, the braking device (not shown) of the spindles and, on the other hand, a time relay which keeps the braking circuit energized for a determined time.
  • the catch 136 operates the switch 126 which cuts the current supply to the brake motor 98, immobilising the ring carrying rails in the underwinding position F (FIG. 5).
  • the regulation of the catches 134 and 135, as well as the regulation of the time relay of the braking circuit, are such that the spinning frame delivers just the necessary length of thread to constitute the underwinding reserve. This latter may be reduced with precision to the desired length.
  • the same switch 126 short-circuits the automatic control circuit.
  • the driving member (here the star 47), the fundamental movement backing-up member (here the gear 48) and the member (here the sun gear 43) of the first differential common to the second differential could be constituted by elements other than a sun gear, the satellite carrier and the other sun gear of this first differential, respectively.
  • the driven member here the pulley 46
  • the mobile backing-up member here the pinion 42
  • the member here the satellite carrier 44
  • a winding control device for controlling up and down movement of the ring-carrying rails of a continuous ring spinning frame or the like, such as a continuous twisting frame: said device comprising, in combination, a first and a second differential, both differentials having at least three elements, including one element common to both; said first differential having a driving member as one of its elements; and the three elements thereof including a first sun gear, two satellite elements and a scond sun gear; said second differential having a driven member as one of its elements; and the three elements thereof including a first sun gear, two satellite elements and said driven member; said driving member being mounted for oscillation; said driven member being connected to the rails, and a further element of said second differential being arranged selectively to be held fixed, to be driven in one direction to effect overwinding, or to be driven in the other direction to effect underwinding; a ratchet wheel connected to a further element of said first differential; a first pawl carried by said driving member and engaged with said ratchet wheel; a pi
  • said driving member of said first differential and said element common to both differentials constitute satellite carriers, each carrying said satellite elements of the respective differential; one of the two satellite elements of the first differential being operatively connected to said further element of the first differential and the other being in mesh with said common element; one of the two satellite elements of the second differential being operatively connected to said further element of the second differential and the other being in mesh with said driven member.
  • a device as claimed in claim 3, further including a reduction gearing interposed between said further element and a satellite element of said second differential, and constructed and arranged so as not to modify the direction of rotation.
