Definitions

  • the object of the present invention is to produce a machine with multiple revolving baskets intended to be used as a hydro-extractor for yarns wound on reels.
  • the yarns in bobbins at the end of the immersion operation in the dye bath, pass to the hydro-extraction station after having been placed inside rotating baskets arranged according to different circumferences which leave from the outside of said baskets and which converge towards the center.
  • the publication DE-C-519044 describes a centrifugal machine for the liquid treatment and for the wiping of warp beam yarns and coils.
  • this machine it is provided that for the regulation of the conditions of the bath is disposed an ejector which causes the rotation of the liquid in the tank, while at the same time large quantities of liquid are inserted into the cycle.
  • the object of the invention is to provide a hydro-extractor for yarns in spools, provided with rotating baskets inside which are placed the spools of yarns supported by appropriate arms (which form the loaders) and allowing said spools to be move only in the radial direction by means of slots made in said arms, which slots allow, under the effect of centrifugal force, the support of the coils against the inner wall of the baskets.
  • each of the assemblies comprising the rotating basket, its control shaft, the sleeve for guiding this shaft and the hydraulic motor, is suspended from a suitable elastic device supported by three series of springs working in traction, while a series of shock absorbers compensates for any imbalance in the load placed inside the rotating baskets, giving rise to a perfectly uniform and silent rotational movement even at high speeds (1500 rpm), which is particularly advantageous with regard to the efficiency of the machine and its silent nature.
  • the reel-loaders are supported by a hydraulically controlled carousel and constituted by a cross formed by four arms; this carousel can be lifted for the extraction, outside of the baskets, of two reel loaders already treated, turn 180 ° and descend by introducing two new loaders into the baskets and simultaneously bringing the two other baskets already treated onto a tray appropriate loading and unloading, so that during the centrifugation dead time the operator has the possibility of preparing the two subsequent loaders, by unloading them from the coils already treated and by loading them with those to be treated.
  • the whole assembly is of course provided with the various controls which are necessary for the automatic realization of the entire operating sequence, namely: engagement of the loaders in the rotating baskets with closing of the lids, start of the centrifugation cycle, stopping, opening of the covers and extraction of the treated magazines, rotation of the carousel with installation of new magazines to be treated, closing of the covers and beginning of a new cycle.
  • the machine comprises a first group formed in this case by two envelopes or fixed outer tanks referenced 1 and 2, inside which rotate the baskets 3 supporting the magazines 4 of which the covers are seen 5 and 6 in the aforementioned figures, while the other two 7 and 8 are located outside said tanks by overcoming the two other chargers which are arranged on the plate loading 9 in order to be discharged from the coils already treated and to be recharged with coils to be treated.
  • the covers and the chargers are mounted on a four-arm rotating carousel referenced 10, which is provided with a central shaft 11 and which is rotated by a hydraulic control cylinder 12; it is intended that the whole assembly can be raised and lowered by being guided by the column 13 with a double T profile, and this by means of an appropriate carriage 14 actuated by a hydraulic cylinder 15.
  • buffers 21 are provided mounted on a fixed post on corresponding uprights 22.
  • Shock absorbers 23 fixed on the one hand by means of suitable staples 24 to the aforementioned uprights 22, on the other hand to spacers 25 integral with the oscillating frame 19, significantly reduce the noisiness of the mobile assembly during the centrifugation operation.
  • the electrical control panel 26 allows the actuation of a small hydraulic unit 27 comprising an electric motor 28, a triple pump housed inside a block of solenoid valves 29 and a heat exchanger 30 (fig. 3) for heating the oil, the latter supplying the entire installation both at low and high pressure.
  • a mobile support for a coil which support is formed by a core 31 with a frustoconical profile (this core can also be cylindrical) fixed in an elastic manner, by means of a stop 32, a spring 33 and a deformable pin 34, to the base element 35: the latter is provided with a lower guide 36 which can move inside the slots provided in the arms 37 and 38 (fig. 5) of the magazines described later in more detail, with reference to figs. 7 to 10.
  • provision may be made to engage the coils on radial bars 39 and 40 (FIG. 6) fixed to a central sleeve 41.
  • This arrangement is adopted for very delicate types of yarn.
  • FIG. 9 and 10 clearly show the cross section IX-IX, respectively X-X, of the arm 42.
  • the particular embodiments of the machine have been given by way of nonlimiting example, said machine obviously being able to be produced in a different way, in particular according to its capacity, that is to say the number and the volume of the coils to be treated. More specifically, the loader arms can be five, if or eight per row, while retaining the other characteristics of the machine.
