Definitions

  • the present invention relates to an accumulation yarn feeder provided with a weft braking device controlled by feedback.
  • a generic yarn feeder can comprise a drum which supports a yarn which is wound onto it and is adapted to unwind it when requested by a generic textile machine, such as a knitting machine or a weaving machine. Before entering the textile machine, the yarn that unwinds from the drum passes through at least one weft braking device, which controls its mechanical tension.
  • the weft braking device is constituted by a hollow frustum-shaped body which is pushed elastically against the output end of the drum by a radial arrangement of springs.
  • the inner ends of the springs are anchored to the smaller end face of the frustum-shaped body and their outer ends are anchored to an annular support. The latter can move axially under the actuation of a screw-and-nut mechanism actuated by a motor.
  • the yarn in output from the feeder slides while pressed between the drum and the hollow frustum-shaped element, thus receiving a braking action by friction.
  • the motor that controls the screw-and-nut mechanism is controlled by feedback by a loop which modulates the braking action applied by the weft braking device on the basis of the signal received by a tension sensor.
  • the main aim is to keep the tension of the yarn fed to the machine downstream substantially constant on a preset value.
  • Known weft braking devices controlled by feedback are capable of applying relatively low braking forces, for example on the order of 20 cN in knitting processes, whereas some applications require higher yarn feed tensions, up to 100-200 cN.
  • EP 2829647 in the name of this same Applicant teaches to provide the yarn feeder with a second braking device.
  • the first braking device is of the frustum-shaped type described above but is passive, i.e., it is not controlled. In practice, a preset braking force is set by acting on a knob.
  • the second braking device is of the comb type and is controlled by a step motor.
  • a tension sensor measures the tension of the yarn that unwinds from the drum and sends a corresponding tension signal to the control unit, which drives by feedback the comb-type brake so as to stabilize the tension of the yarn on a desired value.
  • US 5 476 122 A discloses an active weft braking device having weft braking laminae, which are only controllable by a stepping motor, but it does nowhere indicate, that the weft braking laminae can further be adjusted by auxiliary manual adjustment means.
  • the aim of the present invention is to provide an accumulation yarn feeder provided with a weft braking device controlled by feedback that is capable of applying considerably higher braking forces than traditional systems provided with a single braking device controlled by feedback, for example of the frustum-shaped type, but at the same time is simpler to provide with respect to systems with a comb-type brake such as the one described in EP 2829647 .
  • an object of the invention is to provide a controlled weft braking device which, when needed, can also be adjusted manually, acting in practice as an auxiliary passive break.
  • an accumulation yarn feeder 10 comprises a drum 12 on which a yarn Y is wound.
  • a generic textile machine such as a weaving machine (not shown)
  • the yarn unwinds from the drum 12, passes through a braking assembly supported by an arm 16 that is integral with the drum 12, and finally is fed to the textile machine.
  • a flywheel 17 driven by a motor M winds new turns, drawing yarn from an upstream spool (not shown).
  • the braking assembly comprises a passive weft braking device 18 of the conventional type, which is adapted to apply a preset uncontrolled braking action to the yarn that unwinds from the drum 12.
  • the passive weft braking device 18 comprises a hollow frustum-shaped body 26, which is pushed elastically with its internal surface against the output end 12a ( Figure 3 ) of the drum 12.
  • the hollow frustum-shaped body 26 is supported coaxially to the drum 12 by a radial arrangement of springs such as 27.
  • the springs 27 have their inner ends anchored to a ring 28 which is fixed to the smaller end face of the hollow frustum-shaped body 26 and their outer ends anchored to an annular support 29.
  • the latter is connected to the arm 16 so that it can move axially under the actuation of a screw-and-nut mechanism (not shown) which is incorporated in the arm 16 and can be actuated manually by means of a knob 34.
  • the arm 16 Downstream of the passive weft braking device 18, the arm 16 supports a first thread guiding bush 35.
  • the braking assembly furthermore comprises an active weft braking device 36, which is supported directly downstream of the first thread guiding bush 35 by a longitudinal bar 37 which is fixed to the arm 16.
  • the controlled weft braking device 36 comprises a box-shaped receptacle 38, which is closed by a lid 38a which is fixed by means of a screw 39.
  • the receptacle 38 is provided with an annular engagement tab 38b, by means of which it is fixed to the longitudinal bar 37.
  • the annular engagement tab 38b is fitted on the longitudinal bar 37 and is locked thereon by means of a threaded grub 38c.
  • the receptacle 38 rotatably supports two parallel pivots 40a, 40b which are substantially perpendicular to the axis of the drum.
  • the pivots 40a, 40b integrally support at one end respective gear sectors 42a, 42b which mutually mesh and are received inside the receptacle 38.
  • pivots 40a, 40b exit from the receptacle 38 and have respective pairs of weft braking laminas coupled thereto.
  • each pair of weft braking laminas comprises an internal weft braking lamina 44a, 44b and an external weft braking lamina 46a, 46b, which are extended in a flag-like configuration in the same direction, are screwed on respective opposite flattened faces of the respective pivot 40a, 40b and, in the example illustrated herein, are substantially mutually parallel.
  • the pivots 40a, 40b are rotated so as to move the free ends of the internal weft braking laminas 44a, 44b and of the external weft braking laminas 46a, 46b into mutual abutment under the actuation of an electric motor, advantageously a step motor 48.
  • the step motor 48 is provided with a driving shaft 50 which integrally supports a worm screw 52 which meshes with one of the two gear sectors, the gear sector 42a in the example of embodiment described and illustrated herein.
  • a wheel 56 for the optional manual adjustment of the angular position of the pivots 40a, 40b and accordingly of the contact pressure between the free ends of the weft braking laminas is also connected to the end of the driving shaft 50.
  • the yarn in output from the first thread guiding bush 35 slides between the two internal weft braking laminas 44a, 44b and the two external weft braking laminas 46a, 46b of the controlled weft braking device 36, receive a braking action by friction which is variable as a function of the pressure between the free ends of the weft braking laminas.
  • the active weft braking device 36 is controlled by feedback by a control unit CU (shown only schematically in Figure 3 ) in order to keep the tension of the yarn transferred to the machine downstream substantially stable on a desired value.
  • a control unit CU shown only schematically in Figure 3
  • control unit CU is programmed so as to drive by feedback the step motor 48 on the basis of the tension signal T received from a tension sensor 66, which is supported by the bar 37 downstream of the active weft braking device 36, directly after a second thread guiding bush 64.
  • the braking force can also be adjusted manually on a preset value by means of the wheel 56, by virtue of the non-reversibility of the transmission means that connect the weft braking laminas to the step motor, i.e., the gear sectors and the worm screw.
  • control unit CU The programming of the control unit CU falls within the normal knowledge of the person skilled in the art and therefore is not further described.
  • a manually adjustable stabilizer brake 68 is supported downstream of the tension sensor 66.
  • first of all the minimum desired tension level is set by adjusting manually the passive weft braking device 18.
  • the active weft braking device 36 amplifies the braking action applied by the passive weft braking device 18 so as to stabilize the supply tension on a preset value.
  • the maximum braking level that can be applied by the active weft braking device 36 is much higher than the maximum tension values that can be reached by traditional weft braking devices.
  • the applied braking level can be compared with that of the system described in EP 2829647 , already cited earlier.
  • the system according to the invention allows, if necessary, to adjust the braking force even manually by means of the knob 56.
  • the active weft braking device 36 acts in practice like an auxiliary passive brake.
  • weft braking laminas are movable, as an alternative only one of them might move with respect to a fixed abutment, which might be another lamina, a rigid wall, or other similar element.
  • the transmission means interposed between the step motor and the weft braking lamina might be modified.
  • one of the weft braking laminas might translate under the control of a set of teeth in a meshing relationship with the worm screw connected to the step motor.
  • the transmission means would be of the non-reversible type, allowing auxiliary manual adjustment in a manner similar to the embodiment shown.
  • step motor has always been made in the embodiment described herein, it is of course possible to use other types of electric motor, in particular brushless motors.
