Definitions

  • the present invention relates to textile machines and, more particularly, pin benches for long fibers and short fibers, and relates to a safety device for such a pin bench provided with an automatic lifting device.
  • the spindle benches are generally equipped with two rows of spindles arranged on the spindle carriage, if necessary in staggered rows, and to which correspond two rows of fins.
  • Each of the latter is provided with a pivoting pressing finger, provided with a counterweight which, during the rotation of the fins, folds the corresponding pressing finger against the bobbin or, respectively, against the coil in formation.
  • Such a device is known from US-A-4369621.
  • the automatic lifting device is mainly in the form of a fork, the teeth of which are introduced, by a translational movement of said fork, between the coils arranged on the pins of the pin-carrying carriage, parallel to the transverse alignment of said coils and spindles after the lowering of said spindle carriage and breaking of the wick.
  • the extraction of said coils then consists, on the one hand, in disengaging them from their corresponding pins by a vertical movement of the fork and, on the other hand, in removing them from said pin-carrying carriage by a translational movement opposite to that performed during the engagement of said fork between said coils.
  • said fins must be stopped in such a way that their branches are arranged perpendicular to the direction of translation of said fork.
  • the pressing fingers of the rear row fins are located towards the rear and the pressing fingers of the front row fins are located towards the front.
  • the extraction of the coils can therefore be carried out without risk, the front pressing fingers opening, that is to say pivoting outwards, during the passage of the coils.
  • the front pressing fingers opening that is to say pivoting outwards, during the passage of the coils.
  • the pressing fingers of the fins of the front row are open so as not to obstruct the introduction horizontal of said coils.
  • the object of the present invention is to guarantee the opening of the pressing fingers of the fins of a pin bench to facilitate the positioning of the empty bobbins by the fork of an automatic lifting device.
  • a safety device for a bench with spindles provided with an automatic lifting device, characterized in that it is in the form of profiles arranged, each on one of the teeth of a fork of the automatic device for discharging full reels and for supplying empty reels and provided with deformable longitudinal elements acting on the counterweights of the pressing fingers of the fins of the front row during movement of said fork between said fins, in such a way that the corresponding pressing fingers are, respectively, either pivoted in the open position and held in this position, or folded towards the inside of the fins, according to the direction of movement of said fork.
  • the safety device is in the form of sections 1 each arranged on one of the teeth 2 of a fork 3 of the automatic device evacuation of full 4 reels and supply of empty 5 reels provided with deformable longitudinal elements 6 acting on the counterweights 7 of the pressing fingers 8 of the fins 9 of the front row 10 during movement of said fork 3 between said fins 9, such that the corresponding pressing fingers 8 are, respectively, either pivoted in the open position and held in this position, or folded inwards of the fins 9, according to the direction of movement 11 or 12 of said fork 3 .
  • the profile 1 and the deformable longitudinal element 6 have a length corresponding to that of the stroke of the fork 3 between the fins 9, so that, during any the introduction phase of the empty bobbins 5 between the fins 9, maintaining the pressing fingers 8 at the opening is ensured.
  • the longitudinal element 6 is in the form of a flat elongated brush, but the latter may also include a round, oval or other section.
  • the deformable longitudinal element 6 is in the form of either a velvet ribbon, a purlin strip or an elongated element made of foam rubber.
  • a safety device for a spindle bench provided with an automatic lifting device comprising, in particular, a fork 3 conveyor.
  • Said safety device makes it possible to guarantee an automatic positioning of the 5 empty bobbins without risk of damage to the pressing fingers 8 of the fins 9 as well as a pressing of said pressing fingers 8 against the bobbins 5 in place and, consequently, good attachment of the broken lock to the velvet 13 of said bobbins 5.
