Definitions

  • the present invention relates to the textile industry, and more particularly to straight combing machines, and relates to an automatic compensation device for the wear of the circular brush of a straight combing machine.
  • the short fibers On a straight comb, the short fibers, the length of which can be adjusted, are separated from the long fibers by the circular comb and by the fixed comb. These short fibers thus eliminated form the blister.
  • the circular comb therefore brings its coat onto the circular brush which is discharged from it by the doffer. The pod is then detached from the doffer and collected in the pod tray.
  • the circular brush enters the bars of the circular comb to take out the blister and bring it to the doffer.
  • the circular brush rotates faster than the circular comb to clean it well. Therefore, by entering the bars of the circular comb, the tufts of the circular brush are pushed back and, after a certain time, remain folded back and are therefore considerably worn.
  • the object of the present invention is to overcome all the aforementioned drawbacks arising from the wear of the circular brush of a combing machine.
  • a device for compensating the wear of the circular brush of a straight combing machine characterized in that it is automatic and in that it is essentially constituted by an automatic control device, controlling the position of the circular brush and controlling the movement thereof, by means of at least one actuator, in at least one direction perpendicular to its axis.
  • Figure 1 of the accompanying drawings shows a fixed comb assembly 1 - circular comb 2 - circular brush 3 - doffer 4 - detaching comb 5 of a straight comb combing a ribbon 6 of fibers.
  • the device for compensating the wear of the circular brush of a straight combing machine is automatic, and is essentially constituted, as shown more particularly in FIGS. 2 and 3 of the appended drawings, by a control device.
  • automatic 7 controlling the position of the circular brush 3 and controlling the movement of the latter, by means of at least one actuator 8, in at least one direction perpendicular to its axis 9.
  • the circular brush 3 can therefore more or less approach the circular comb 2 and / or the doffer 4 according to its direction and its direction of movement. If, therefore, the circular brush 3 approaches the circular comb 2, the tufts 10, with which it is furnished, penetrate, even if they are bent or folded, between the needles 11 of the circular comb 2 to their base and therefore rid them completely short fibers that clutter them. On the other hand, the needles 12 of the doffer 4 do not penetrate into the tufts 10 of the circular brush 3, but remain tangent to the latter and may even have a small play with them.
  • the position of the circular brush 3 must therefore be such that it ensures, on the one hand, an optimal interpretation between the circular brush 3 and the circular comb 2 and, on the other hand, the tangency between the circular brush 3 and the doffer 4.
  • the actuator 8 consists of an electric motor 13, reversible or provided with a reduction gearbox 14, controlled by the automatic control device 7, and by a mechanical device 15, transforming the movement of rotation of said electric motor 13 in translational movement of the circular brush 3.
  • the mechanical device 15 consists of a shaft 16, rotated by the electric motor 13, said shaft 16 carrying two pinions 18 and 18 ′ meshing, each with a pinion with corresponding perpendicular angle 19 or 19 ′, integral with a screw 20 or 20 ′ subject in translation by a stop 21 or 21 ′, and each actuating a movable bearing 22 or 22 ′.
  • each movable bearing 22 or 22 ′ comprises a bearing 23 or 23 ′ as end support for the axis 9, as well as a nut 24 or 24 ′, cooperating with the screw 20 or 20 ′ of corresponding drive, and allowing the displacement in translation of the axis 9 of the circular brush 3, in a horizontal plane, in a direction perpendicular to the axes of the circular comb 2 and of the doffer 4 and in one of the two directions of displacement 35 or 36, depending on the direction of rotation of the shaft 16 ( Figure 2).
  • a mechanical device 15 as described above, mounted on a frame 17, ensures synchronous movement of the two mobile bearings 22 and 22 ′, and therefore retains the parallelism between the circular brush 3, on the one hand, and the doffer 4 and the circular comb 2, on the other hand.
  • the actuator 8 is constituted by the mechanical device 15 and by a ratchet wheel driven by a pawl actuated by a jack, either pneumatically or operationally hydraulic.
  • the ratchet wheel is then mounted directly on the shaft 16 and replaces, in this case, the electric motor 13.
  • the device which is the subject of the invention comprises pneumatic or hydraulic jacks 25, 25 ′ allowing the circular brush 3 to be locked in place in its position, controlled by the automatic control device 7. job.
  • This locking takes place in synchronism with the movements of movement of the axis 9 of the circular brush 3.
  • the automatic control device 7 comprises a programmable servo 26, as well as sensors 27, making it possible to adjust the periodicity and the value of the horizontal displacement of the circular brush 3, to achieve a controlled force locking thereof and, to fix, by driving it with an electric motor 28 at variable speed, the speed of rotation of said circular brush 3, depending on or independently of its position.
  • the drive of the circular brush 3 can also be carried out by means of sprockets, chains or belts.
  • the device, object of the invention also includes a display device 29, making it possible to constantly check the position and the state of the circular brush 3, as well as the data of the sensors 27.
  • the device, object of the invention includes an automatic stop of operation 30 of the straight combing machine, connected to at least one limit switch 31, as well as at least one device 32 for indicating the wear of the tufts 10 of the circular brush 3, such as, for example, an indicator light, an audible warning, etc.
  • the wear signaling device 32 therefore warns the user of the imminent need for a change of the circular brush 3, hence the possibility of a preliminary organization of this change, and therefore a saving of time in machine stop. .
  • the automatic operating stop 30 comes into action when the circular brush 3 is completely worn out, and stops the combing machine.
  • the device according to the invention further comprises manual displacement control means 33, usable after disconnection of the automatic control device 7 using a selection device 34 of manual or automatic movement mode.
  • the sheet of incoming fibers 6 is combed, on the one hand, by the circular comb 2 and, on the other hand, by the fixed comb 1.
  • the short fibers thus removed from the sheet of incoming fibers 6 form the blister which agglomerates on the circular comb 2.
  • the latter is discharged from its blister and cleaned by the circular brush 3.
  • This cleaning operation of the circular comb 2 is carried out because, said circular comb 2 and the circular brush 3 rotating respectively in the directions of rotation indicated in FIG. 1, the circular brush 3 rotates faster than the circular comb 2.
  • the doffer 4 also rotating in the direction of rotation indicated in FIG.
  • the veil 6 ′ composed only of long combed fibers, is then reformed on a tear-off leather, condensed into a ribbon by a funnel and placed in a pot by rollers.
  • the combed tape, produced from the veil 6 ′, constitutes the product leaving the rectilinear combing machine.
  • the motor 13 rotates the shaft 16 on which are mounted the pinions 18 and 18 ′ which transmit the rotation respectively to the pinions 19 and 19 ′ secured to the screws 20 and 20 ′.
  • the latter held in translation by the stops 21 and 21 'move, by their rotation, the bearings 22 and 22' which support, via the bearings 23 and 23 ', the axis 9 of the circular brush 3.
  • the displacement of the circular brush 3 is done according to arrows 35 and 36, namely in the direction of arrow 35, in normal operation, that is to say when it is necessary to compensate for the wear of the tufts 10, and in the direction of arrow 36 when it is necessary to disengage the circular brush 3 to replace it.
  • the wear compensation of the circular brush 3 can be done continuously or periodically.
  • the constant cleanliness of the circular comb 2 ensures a better quality of work for the rectilinear combing machine, this constant cleanliness being due to the very regular cleaning of the circular comb 2. In fact, the circular comb 2 being cleaned more efficiently , the outgoing product is automatically of better quality.
  • the automatic wear compensation of the circular brush 3 has an extended service life and is, in general, better exploited. In addition, it also avoids many stops of the machine, hence a significant contribution to increasing the performance of the straight combing machine.
