Definitions

  • the present invention relates to a mechanism for a continuous spinneret.
  • the document DE-A-2,934,867 describes a device of this kind, that is to say with false pretortion, with a tubular pin vertically fixed between which passes the wire in formation, a hollow body rotating around said pin and supporting the wire stretching cylinders which derive their rotational movement about their axes from that of rotation of said body, means for detaching the wire in formation from the stretching cylinders by an electromagnetic control which is activated / deactivated at intervals regular and in synchronism with the production speed of the wire in order to avoid / obtain the false pretortion.
  • the real pre-torsion devices proposed so far require two movement controls, one for torsion and the other for stretching, with a consequent expenditure of mechanical means and motive power; they involve technical complications such as excessive congestion, high noise, lubrication problems and also irregularities in stretching and the number of twists per meter in the event of even slight variations in the relative speed between the organs of movement primary torsion and those of the movement that determines the stretch; in addition, they do not allow the automatic introduction of the wick through the stretching group with a stopped or moving spinneret, and finally, in the event of breakage of the wire, downstream of the stretching group, it is wound on the cylinders of said stretching group, forcing, for its recovery, to stop all the spindles of the spinner.
  • the present invention aims to eliminate the drawbacks of prior devices and thus allow the adoption of stretch with real pretortion in a continuous spinneret by improving production, facilitating maintenance and ensuring correct operation for very long periods of time without mechanical repair.
  • a mechanism for a continuous spinner comprising a mechanism for a continuous spinner comprising a stretching group (8, 9) rotating around the vertical axis of the wire in formation (7), a hollow body (1) rotating around a tubular journal (2), fixed, coaxial with the body (1) and further supported by a fixed part (3) of the spinneret, and in which body (1) is installed the group of stretching whose cylinders (8, 9) derive their rotational movement about their own axes from that of rotation of the body (1) characterized in that inside said pin (2) is located in a metal tube (5) for the passage of the forming wire (7), which is fixed to the body (1) and rotates integrally with the latter and concentrically with the pin (2); and in that inside the metal tube (5) is generated a current of air which moves around and in the direction of advance of the wire in formation (7) and moreover, around the cylinders (8, 9) of the stretching group in the opposite direction to the movement of these and finally exits through the outlet orifice
  • Said gear train and the bearings of the corresponding shafts are lubricated by means of an oil lubricator in cooperation with the centrifugal effect which derives from the rotation of the mechanism.
  • the means for obtaining the simultaneous stretching and twisting are rigidly assembled together, so that, in addition to having a single control of the movement, the twists are distributed uniformly over the entire piece of wire between the feed group and the stretch group and between the latter and the thread receiving spindle; that the head of the wick, at the outlet of the feeding group, is automatically introduced into the stretching group with the spinner in motion; that the wire in formation is prevented from coming into contact with the fixed part of the spinner; that, in the event of breakage, the wire is prevented from being wound on the cylinders of the stretching group and, moreover, pushed down, vertically, avoiding the centrifugal and aerodynamic effects of the rotating part of the mechanism; that the air flow also allows automatic and continuous cleaning of the stretching group; that it is possible to use a spinneret for very long periods of time and continuously without mechanical repair.
  • a mechanism for a continuous spinneret includes: - A body in two pieces 1,1 ⁇ with a first cavity 10 open upwards and communicating with a second lower cavity 12, which is provided, at the bottom, with an orifice 15 for the exit of the wire in formation 7; said body is mounted, by means of bearings 16, on a hollow pin 2 which is in turn fixed vertically to a fixed part 3 of the spinneret and the mouth 13 of which is advantageously flared to falicitate the introduction of the wire in formation 7: the rotational movement of the body 1,1 ⁇ being derived, that is to say obtained from a control member (not shown) by means of a belt 4 and a corresponding pulley 14.
  • Said pin 2 is d 'a single piece with an endless screw 21 and inside, is installed a metal tube 5 coaxial and fixed, by its lower end, to the body 1.
  • the pin 2 Near the orifice 13 for introducing the forming wire 7 , the pin 2 is provided with a nozzle 20 inclined downward, for the introduction of compressed air intended to generate a current of air inside the metal tube 5 for the control of the wire in formation 7 which s 'moves there in the pre-twist and stretching phase.
  • 1 ⁇ is housed a shaft 6 with a wheel 60 with helical teeth, which is engaged with said screw 21.
  • the rotational movement of the driving cylinder 8 is obtained from the shaft 6 by means of a gear train 81, 82, 83, 84, 85 the wheel 83 of which is advantageously retractable so as to disengage the wheel idler 84 and respectively to engage the wheel 85, in order to reverse the direction of rotation of the cylinders of the stretching group around their axes, and thus to print in thread 7, twists Z and S, respectively: l 'retraction of the wheel 83 being caused, automatically, by the reversal of the direction of rotation of the body 1,1 ⁇ .
  • the air stream which exits through the metal tube 5 is directed towards the outlet orifice 15 through the space 91 surrounding the cylinders 8, 9 of the stretching group, cleaning their surface, which moves in the opposite direction from the direction of movement of air flow itself.
  • the transmission between the screw 21 and the cylinder 8 of the stretching group makes it possible to obtain the stretching and the pre-twisting of the wire in formation 7 by means of the rotation of the single body 1,1 ⁇ which can be done at high speed and with a low torque.
  • the yarn obtained is always regular because the stretching group 8, 9 and the rotating 1.1 corps body are rigidly assembled together, so that any regularity errors in the yarn which would be due to it are avoided. to small variations in speed between the two rotating members.
  • the number of turns of the body 1, 1 ⁇ , the transmission ratio of the internal gear train 21, 60, 81-85, and the diameter of the cylinders of the stretching group 8, 9 can vary so suitable for obtaining in the wire a number of twists per meter between 10 and 400
  • an improved variant of the mechanism of FIG. 2 includes:
  • a hollow body 1 for receiving a structure 100 which is mounted by means of bearings 16, 16 ⁇ on the hollow pin 2 vertically integral with a fixed part 3 of the spinneret, and supports the driving cylinder 8 of the group of stretch and the gear train 60, 81, 82 ⁇ , 85, intended for transmitting the rotational movement of the body 1, obtained from a belt 4 and a pulley 14, from the drive cylinder 8 in cooperation with the worm screw 21 fixed to said fixed journal 2.
  • the walls of said structure 100 delimit , with that of the body 1, three communicating chambers 110 to 112, with the first 110 internal to the structure 100, the second external 111 and the third 112 located above and of diameter greater than that of the chamber 111.
  • Said chambers are intended to contain an appropriate quantity of lubricating oil which is introduced therein via an inlet 140 of the upper chamber 112 and to distribute it to said gear train and to the bearings of the corresponding shafts by the centrifugal effect which derives from the rotation of the body 1.
  • an oiling device 150 is fixed to the pin 2, the folded arms from which advantageously provide for the removal of the lubricant which, during the rotation of said body 1, is present on the wall of said chamber 112 , and its distribution, respectively, to the upper bearing 16 and to the worm gear group, toothed wheel 21, 60, from which it falls on the lower bearing 16 ⁇ : a cannula 151 being provided in the structure 100 for the inlet and the possible drainage of the lubricant to and from the bearing of the wheel shaft 82 ⁇ .
  • the wire in formation which passes in the metal tube 5 can never be reached by the lubricating oil present in the chamber 110 since the base of the said metal tube is tightly fixed to the structure 100.
  • the lubricating oil present in the upper chamber 112 descends through the orifices 113 in the internal chamber 111 and that present in the latter is deposited on the bottom; the quantity is such that its level does not exceed the protective cover or cover 130 of the bearing 131 of the drive roller 8 of the stretching group, so that said roller 8 cannot be reached by the lubricating oil: at this also cooperating with a labyrinth path 115 downstream of said cover.
  • Said cover 130 only allows the passage, in dynamic phase, of the small quantity of oil sufficient for the lubrication of the bearing 131; and if the lubricant were to reach said cushion in excessive quantity, it would be automatically evacuated into the chamber 111 through the passage delimited by the sides of the cover 130 and of the wheel 82 ⁇ .
  • Said slide 190 is further provided with a counterweight disposed in a corresponding space 197, in a diametrically opposite position relative to the spring 191, so as to be statically balanced.
  • a compressed air ejector 141 mounted on an arm 142 supported by the fixed part of the spinner, independently of the body 1, the inlet tube 143 of which is positioned downstream of the stretching group 8, 9 and so collecting the wire in formation at the outlet of the latter and guiding it to the outlet 15 of the device.
  • the compressed air introduced through the conduit 144 arrives in an annular chamber 145 concentric with the said tube 143 and so as to touch the mouth with an inclination of 45 ° or less, this contributing to the blunt edges of the end of the tube 143 and the juxtaposed edge of the ejector.
