Definitions

  • the present invention relates to the textile industry, more particularly the spindle benches for long fibers and short fibers, and has for its object an automatic lifting device for spools on a spindle bench for long fibers and short fibers and a method using implement this device.
  • document EP-A-0 214 837 discloses a device of the type described in the preamble of claim 1.
  • the aforementioned gripping is carried out by simple hooking, without any joining or blocking, which may, if necessary, cause the coils or bobbins of the forks of the forks device to drop, in particular in the presence of jerks, shock, vibration or sudden movement, especially when removing the full coils from the spindle rack.
  • the gripping of the coils or bobbins by the fork device, described in this document, at their upper part requires, for a given length or height of pins, a large space or a greater clearance distance, in particular in the case of very long spindles, in order to avoid any interpenetration of the fork device with the fins.
  • the present invention aims in particular to overcome the aforementioned drawbacks.
  • a device for automatically lifting coils on a bench with spindles for long fibers and short fibers mainly consisting, on the one hand, of a movable transport fork in at least a horizontal direction and, on the other hand, by a conveyor for discharging the full reels and for supplying the empty reels, characterized in that it comprises cups supporting from below and allowing the handling of the full reels and the empty reels by the transport fork, this the latter cooperating with said cups by pinching their edges and being movable in a vertical direction and in a horizontal direction parallel to the transverse alignment of the pins of the pin-carrying carriage.
  • the subject of the invention is also a method of automatic lifting of spools on a spindle bench for long fibers and short fibers using the above-mentioned device and consisting, after the winding of the spools has ended, breaking the wick and releasing coils full of their corresponding fins, if necessary by lowering the spindle carriage, extracting said coils full of their corresponding pins and transporting them to an overhead conveyor, characterized in that it consists in extracting and transporting said coils by means of a conveyor fork cooperating with cups threaded on said pins and each supporting a coil, then hooking said coils to empty reel carriers of said conveyor, the cups remaining integral with the fork, then unhooking empty bobbins in equal number of said conveyor using said cups, to transport them to the pins li of said spindle carriage, then threading them, together with the cups which support them, on said spindles and, finally, to disengage said conveying fork from said threaded cups and to bring it into a dis
  • the device for automatically lifting coils on a spindle bench 4 for long fibers and short fibers consists mainly, on the one hand, of a movable fork 1 conveyor following at least a horizontal direction 3 and, on the other hand, by a conveyor 9 for discharging the full reels 7 and for supplying the empty reels 8.
  • this device comprises cups 6 supporting from below and allowing the handling of the full coils 7 and the empty coils 8 by the conveyor fork 1, the latter cooperating with said cups 6 by pinching their edges 12 and being movable in a vertical direction 2 and in a horizontal direction 3 parallel to the transverse alignment of the pins 4 of the pin holder carriage 5.
  • the fork 1 conveyor is equipped with pads 10 with springs 11 allowing the edges 12 of the cups 6 to be pinched when handling the full coils 7 or empty coils 8 and thus avoid any displacement of said cups 6 relative to the fork 1.
  • the width l of the conveyor fork 1 corresponds to a fraction of the length of the spindle carriage 5, said fork 1 also being movable in a direction 13 parallel to said spindle-carrying carriage 5.
  • Automatic lifting can be carried out, for example, in groups of eight coils 8.
  • the automatic lifting process will then have to be repeated as many times as there are sections of eight spindles 4 on the spindle-carrying carriage 5. The passage from one section to the other will therefore be done by displacement of the fork 1 following direction 13.
  • the conveyor fork 1 composed, where appropriate, of several independent segments, extends over the entire length of the spindle-carrying carriage 5.
  • the control of this fork 1 can, therefore, be either fractional, in the case of a constitution in several segments, or general, in the case of a fork 1 in one piece. It is then possible to carry out the lifting of all the coils 7 in a single operation; this results in increased profitability due to a shorter operating stop of the spindle bench.
  • the automatic lifting device further comprises a safety device activated when the fork 1 conveyor is actuated and provided with means audible and / or light alarms, said device also making it possible, if necessary, to delimit a safety zone around the pin bench in question.
  • the subject of the invention is also a method of automatic lifting of coils 7 using the device described above, method consisting, after the winding of the coils 7 has ended, breaking the wick and disengaging the coils 7 full of their corresponding fins 14, if necessary by lowering the pin-carrying carriage 5 (FIG. 1A), extracting said coils 7 full of their corresponding pins 4 (FIG. 1B) and transporting them to an overhead conveyor 9 (FIG. 1D) , by means of a conveyor fork 1 cooperating with cups 6 threaded on said pins 4 and each supporting a coil 7, then hooking said coils 7 to empty coil carriers 15 of said conveyor 9 (FIGS.
  • the extraction of the coils 7 full of their pins 4 consists, first of all, in bringing the fork 1, from its rest position, opposite the pin-carrying carriage 5 and at the height of the cups 6, then introducing said fork 1 between the pins 4 by a horizontal translational movement, so as to engage the cups 6 between the pads 10 with spring 11 and the corresponding slides 16 and, finally, to thread the cup assemblies 6 - coils 7 of their corresponding pins 4 by a vertical movement of said fork 1.
  • This positioning of the coils 8, towards the pins 4 consists in carrying out, by means of the fork 1, the reverse movements of those described above for the extraction of the coils 7, and this in reverse order.
  • the operations for hooking up the full reels 7 and for removing the empty reels 8 are carried out by vertical movements of the fork 1, the arrangement of the reel carriers 15 on the overhead conveyor 9 corresponding to the arrangement of the pins 4 on the pin-carrying carriage 5.
  • the conveyor 9 moves by a length such that it has opposite the 6 empty cups, an equal number of 8 empty bobbins.
  • the actuation of the fork 1 can be achieved, for example, by mechanical means controlled by electrical, hydraulic or pneumatic devices and controlled, if necessary, by a programmable controller.
  • the pads 10 may also, according to an alternative embodiment, be actuated by pneumatic or hydraulic means.
