Definitions

  • the present invention relates to the field of the textile industry, in particular wire processing machines, such as steaming machines, stranding machines, or other and has for object a recovery device and individualization son coming out of a processing machine.
  • the wire to be treated has a good mechanical strength and a large linear density
  • several son to be treated are jointly deposited in the form of parallel turns on the transport means and pass through the steam chamber, then cooled and wound separately.
  • This winding is performed by means of a winder having as many winding units as jointly deposited wires, the winding units operating synchronously.
  • the simultaneous winding of the jointly deposited wires is made possible by the fact that a sufficient voltage can be applied downstream of the winding units, so as to ensure the separation son and thus allow to ensure a correct winding of all son.
  • Devices implementing such methods are in particular known by US-A-3,638,873 , US-A-4,623,101 , US-A-4,574,574 , GB-A-1,214,999 and US-A-4,830,296 .
  • the present invention aims to overcome these disadvantages by providing a device for recovery and individualization of son out of a processing machine for regulating the speed of son leaving a processing machine, before their subsequent processing.
  • the device according to the invention comprises the features of claim 1.
  • the appended drawings show a device intended to be mounted at the output of a son-processing machine, such as a steaming machine, for the recovery of string wires, or the like.
  • this device essentially consists of at least one son individualization means 1, comprising individual wire guiding elements 2 and a traction recovery assembly of the individualized wires, and by at least one means 4 ', 4' individual control of presence of son and speed control son, so as to achieve on said son a soft corresponding to a path of undulating shape before their downstream processing.
  • This device is represented, for example, with a vertical circulation of the wire 3. However, it is also possible to operate said device with son circulation horizontally.
  • the downstream treatment of the wires 3 may consist, for example, as shown in FIG. figure 1 of the accompanying drawings, in a straight or conical winding in a winder 5 having winding devices 6 with crenellated rollers 6 'or flies or moving eyelets (not shown).
  • the winder 5 is provided, in a manner known per se, with devices 7 for guiding and pre-tensioning the wires 3 wound individually on coils 8 of said winder 5.
  • Downstream processing may also consist of other thread processing operations individually.
  • the individual wire guiding elements 2 and the traction recovery assembly of the individualized wires, as well as the individual means or means 4, 4 'for controlling the presence of the wires and regulating the the speed of the son are advantageously mounted on a frame 9 for support and fixation on a downstream processing machine 5 or on an independent chassis (not shown).
  • the individual wire guiding elements 2 are advantageously each in the form of an eyelet mounted on an arm 2 'secured to the frame 9 and extending upstream of the traction recovery assembly of the individualized wires 3.
  • This traction recovery assembly of the individualized son 3 is in the form of at least one drive cylinder 10 actuated at constant speed by a motor 11 and cooperating, at each individual wire 3, with a pressure roller 12.
  • the yarns 3 coming from an upstream processing machine can be perfectly individualized by passing through the eyelets 2 which are assigned to them and then, by passing between the driving cylinder 10 and the pressing roller 12, they are pulled under tension and constant speed out of the docking devices or others provided at the output of the upstream processing machine.
  • the individual means 4, 4 'for controlling the presence of the wires 3 and for regulating the speed of said wires 3 consist essentially of pairs of sensors 4, 4' mounted on the support frame 9 and each assigned to a wire 3, individualized. through the resumption of son assembly 3, these pairs of sensors being each disposed downstream of a pressing roller 12 for feeding the corresponding wire 3 and cooperating with an electronic device (not shown) for controlling and regulation of the means 6-6 'for pulling the threads 3 of a downstream processing machine 5.
  • the sensors forming the individual means 4, 4' each comprise a photoelectric or optical cell 41, 41 'whose axis of detection extends in a recess 42, 42 'of said sensor.
  • one, 4, sensors is disposed near the drive roller 10 and the pressure roller 12, downstream thereof, and the axis of its cell 41 perpendicularly crosses the trajectory wire 3 at the exit of said drive roller 10 and pressure roller 12, while the other sensor 4 'is disposed at a distance from the first sensor 4 and with an offset with respect to the rectilinear trajectory of the wire upstream thereof ci, this other sensor 4 'being provided with an eyelet 13 for guiding the wire 3, extending after said sensor 4' and the cell 41 'and mounted on said sensor 4' via a support 14 ( Figures 1 to 5 ).
  • the thread 3 coming from the thread take-up assembly 3 is then conveyed, after the sensor 4 ', to a downstream processing machine and is guided by means of one or more eyelets 15 ( figure 1 ).
  • the wire 3 tends to extend obliquely between the sensor 4' and the drive rollers 10 and the presser 12 ( figure 4 and 5 ), when the wire 3 receives a certain tension between these two elements.
  • downstream processing machine 5 is a winder and the means 6-6 'for pulling the threads 3 are winding devices 6 with crenellated rollers 6'.
  • the electronic device for controlling and regulating means 6-6 'for pulling the threads 3 of a downstream processing machine 5 can advantageously be constituted in the form of a programmable controller integrating a detecting the presence of wires at the cells 41, 41 'of the sensors 4, 4' and the speed of the wire 3 at the means 6-6 'of pulling the wires 3 of the downstream processing machine 5.
  • Each wire then passes into the corresponding recess 42 of the sensor 4, then is inserted into the eyelet 13 of the corresponding sensor 4 'and then into an eyelet 15 of a processing machine downstream 5 to be brought into it, through a device 7 for guiding and pre-tensioning means 6-6 'traction.
  • the traction recovery assembly of the individualized wires 3 are projected in the direction of the axis passing through the point of contact between the drive roller 10 and the pressure rollers 12.
  • the positional offset between the preceding axis and the axis passing through the center of the outlet eyelet 13 of the device allows the wire 3 to take, at a given instant, a path of undulating shape between these two points, if the speed of the traction means 6-6 'is less than the speed of the traction recovery assembly, a straight trajectory between these two points, if the speed of the traction means 6-6' is greater than or equal to the speed of the traction recovery assembly.
  • the cell 41 of the sensor 4 extending immediately downstream of the drive rollers 10 and presser 12 and the cell 41 'of the sensor 4' extending immediately before the eyelet 13 can detect the presence of a slack on the wire 3 corresponding to a path of undulating shape of the wire.
  • Such slack is particularly necessary in the presence of very thin and very fragile son having to undergo a very limited tension.
  • the electronic control and regulation device cooperating with the sensors 4, 4 'forming the individual means for controlling the presence of the wires 3 and of the regulation the speed of said son 3, delivers a speed regulation signal of said means 6, 6 'tending to lower the speed of traction of the latter so that the wire 3 takes a path of undulating shape between the sensors 4 and 4 ', this path extending through one of its strands in the recess 42' of the sensor 4 '.
  • the wire 3 brought to constant speed by the recovery assembly of the device according to the invention forms an undulating trajectory whose strands are detected by both sensors 4 and 4 '.
  • the electronic control device delivers a slowdown signal allowing traction of the wire at a stabilized speed substantially corresponding to that of supplying said wire to the sensors 4, 4 '.
  • a single multi-zone sensor detecting different positions of the wire 3, that is to say say at least one corresponding to the undulating form and one corresponding to a voltage of the wire 3.
  • a sensor may, for example, be constituted by a multipositions detector simultaneously scanning several zones or by a Doppler-type radar detector.
  • the electronic control device also makes it possible to take into account the differential speed of traction that can be experienced by the wire 3, for example, in the case of a winding on a conical coil ( figure 1 ), as well as swirling during winding. In such cases, the winding speed undergoes variations causing more or less traction on the wire 3. These variations in traction speed can be taken into account by the device according to the invention.
  • the invention it is possible to provide a device for recovery and individualization son out of a processing machine for perfect separation of several son simultaneously processed upstream and their individual recovery constant voltage. This is particularly interesting in the case of recovery of very fine and fragile son.
  • the problem of the loops occurring during the steaming can be solved to a large extent. Indeed, when fine and fragile yarn is treated by steaming, loops deposited for steaming tend, despite the treatment, to maintain some elasticity that may cause the formation of knots following traction on the wire. Due to a multi-wire treatment made possible by the device according to the invention, the loops deposited for vaporization have a greater pitch, namely at least two or even three or more, due to an alternation of turns from several wires, which causes a natural ability of said wires to separate, so that their tendency to reform a loop or a node is considerably lessened.
  • the device according to the invention makes it possible to increase the productivity of the upstream processing unit.
