Definitions

  • the present invention relates to a reduction of speed with one input and several outputs for the command of the wire formation group in a machine for chenille yarn.
  • a chenille yarn consists of two tying threads which are twisted so suitable for engaging ends of an effect thread.
  • track machines include at least one wire formation group, with a "gauge” on which is wound and sized the effect thread, a blade for cutting the ends of effect wire thus wound on the gauge, two drive rollers with counter rollers correspondents, located on the opposite side from to the caliber, to train the binding threads with the ends of the effect thread and the means of recovery and twisting of binding threads with the ends of effect wire interposed.
  • a pair of rollers, or "stretch group” allows control the process, i.e. food, tying threads.
  • a transmission including a speed reducer screw in oil bath which is interposed between a main driving organ and the organs of said group to train, and has several outputs with corresponding cardan shafts.
  • the main object of the present invention is to eliminate the aforementioned drawbacks.
  • the advantages obtained thanks to the present invention basically consist of what is possible drastically reduce the power dissipated by the transmission and therefore the corresponding mechanical efficiency turns out considerably increased compared to that of traditional oil bath reducers; in this that it is possible to achieve a precision high operational for the link between the reducer and the organs of the training group the wire slaved to it, which allows to obtain a very high quality chenille yarn and increase the overall reliability of the machine and extend its operational life; in that a reducer according to the invention does not include exposed parts and offers a high degree of protection against accidents; in that it has reduced dimensions and a very quiet operation.
  • FIG. 1 schematically represents the view of front of a reducer for wire formation group in a machine for chenille yarn in accordance with the invention, on which the primitive diameters of gears including the device is equipped;
  • - Fig. 2 represents the sectional view along line A-A of FIG. 1;
  • - Fig. 3 shows the sectional view along the line B-B of FIG. 1, on a reduced scale;
  • - the Fig. 4 schematically represents the view of front of a chenille wire machine equipped with a wire formation group according to the invention, on which the rollers of the stretching group and on which the machine shown produces two lines of wire caterpillar.
  • said trees (2) and (6) are supported by a structure shell (CF) in two elements (17, 18), fixed on the machine frame (19).
  • Wheel shafts (R5, R4) and respectively (R5 ', R4') are supported by corresponding housings (CM), each of which is made up of two elements (26, 27) and pivotally mounted around the shaft (2), and respectively (6), on said fixed casing (CF), of so that the shafts of said wheels (R5, R4) and (R5 ', R4') can turn rigidly around the shafts (2, 6) of said wheels (R2, R2 ') between two limit positions, one working, that is to say of contact of the wheels (31) with the gauge (32) and shown in solid line in Fig.
  • each housing (CM) is articulated on the housing (CF).
  • Said wheels (R6) and (R7) have the same module and the same number of teeth, so that the rotation speed of rollers of the stretching group is equal to that of wheels (31).
  • the device described above therefore makes it possible to produce the following lines for transmitting the movement: R1 ⁇ R2 ⁇ R3 ⁇ R5 ⁇ R4 R2 ' ⁇ R3' ⁇ R5 ' ⁇ R4' for the wheels (31); R2 ' ⁇ R6 ⁇ R7 for the drawing group; and R2 ⁇ R8 ⁇ R9 ⁇ R10 ⁇ R11 for the blade (L).
  • said wheel (R1) is connected to the shaft (1) corresponding by means of a tongue (7): said shaft (1) being supported by bearings (5) housed in said housing fixed (CF).
  • Said wheels (R2) and (R8) are fixed to the respective shaft (2) by means of a common tongue (8): said shaft (2) being supported by two radial bearings (3), one of which is housed in a corresponding fixed ring (12) located opposite the shaft (2) and the other is housed in a base (11) of the fixed casing (CF).
  • Said wheel (R3) is connected to the shaft (2) by means of a corresponding tongue (9).
  • Said wheel (R2 ') is connected to the respective shaft (6) by means of a corresponding tongue (14) and held in place by means of a spacer (13): said shaft (6) being supported by bearings corresponding radials (15), one of which is housed in a corresponding fixed ring (12) located opposite the shaft (6).
  • Said fixed casing (CF) is centered on said rings (12), which are, in turn, centered on corresponding arms (21) fixed to the chassis of the machine.
  • Each of said wheels (R5, R5 ') is held in place by a corresponding pad (23) mounted on the respective shaft (22).
  • Each wheel (R4, R4 ') is fixed to the respective shaft (24) by means of a corresponding tongue (30).
  • Said wheel (R6) is connected to the corresponding shaft (6) by means of a tongue (16) and held in place by means of the stop action produced by a bearing (4) acting on a base (34) which is housed inside a corresponding housing (41), the base (34) being provided with a seal (35).
  • Said wheel (R7) is connected to the corresponding shaft (37) by means of a tongue (36), the shaft (37) being supported by a pair of juxtaposed oblique bearings (38), housed in a corresponding seat provided in the aforementioned casing (41).
  • a ring (39) provided with seals (40) on both sides is mounted coaxially with the shaft (37) in a position located above the bearings (38).
  • each said trees (24) is hollow, that is to say provided a longitudinal hole for the housing of another shaft (29) with connecting tongue (28), which is provided with an adjustment member (33) for adjusting its axial position and is coaxial to the part upper arm "L” supporting a wheel corresponding (31).
  • said wheel (R9) is mounted by means of a tongue (46) on the corresponding tree (45): said tree (45) being supported by two bearings (47, 48) of which one (47), fixed, is housed in a seat correspondent formed in the element (17) of said first housing and the other (48), oscillating radially, is housed in a corresponding groove of the chassis (19).
  • said wheels (R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R2 ', R3', R4 'and R5') are made of composite material consisting of several superimposed layers of parallel cotton fibers or the like, which are arranged so that the fibers of each layer form an angle of about 45 ° relative to that of the adjoining layers and treated with epoxy binder.
  • a composite material of the type mentioned is known in Italy under the trade name "FERROZEL" type KLFF.
  • the device described above makes it possible to transmit the movement to the blade (L) enclosed in a corresponding casing, as illustrated in FIG. 3, which allows it to be adjusted even during its rotation.
  • the reduced size of this device makes it possible to position textile dust extraction means on the machine for chenille yarn, which proves to be extremely difficult with the use of traditional reducers.
