Definitions

  • the invention is related to the technical sector of textile machines, including digging operations.
  • the invention finds particular application in the field of textile machines, wiring, twisting son, texturing, and more generally son transformation.
  • the problem in this type of textile machines is in particular to be able to remove and unload the tubular supports on which are formed the son coils to replace them with empty tubular supports and relaunch the production of a new coil.
  • the first automatic systems were developed more than 50 years ago for winding natural or synthetic yarns, especially for spinning processes.
  • the patent GB 1024615 from 1963 discloses, by way of example, a device intended to be integrated in a winder, the principle of which prefigures the one still used today. This device is individual, that is to say, integrated in each winding position.
  • the patent US 3344594 from 1964 discloses a means of performing the function for machines having an alignment of work positions arranged side by side, such as cabling, twisting or texturing machines.
  • the invention relates to a textile machine of the type comprising, in a manner perfectly known to those skilled in the art, at least one motorized receiving cylinder (R) of wire (F) subject to a system of back and forth (V) for the formation of a coil (B) on a rotating tubular support (S), mounted in gripping and positioning means (P) usually called “fork” by the skilled person.
  • the empty tubular supports are pre-positioned in a distributor magazine (M).
  • the finished coils (B) are evacuated by a ramp (Ra) or other means.
  • the thread (F) is cut in a suction ( figure 1 ).
  • the coil (B) is disengaged from the receiving cylinder (R) by displacement or rotation of the fork (P), to be braked and released, for example, on the discharge ramp (Ra) located on the opposite side to the arrival of the thread (F) ( figure 2 )
  • the manipulation of the coil (B) is carried out by the means (P). After release, the coil (B) rolls by gravity to the bottom of the discharge ramp (Ra) for later retrieval.
  • the distributor of tubular supports (M) then pivots to place another tubular support in the fork which thus has gripping and positioning means (P) ( figure 3 ).
  • the fork (P) applies, by displacement or rotation, again the tubular support (S) against the receiving roller (R), for another winding operation.
  • the distributor (M) returns to its initial position ( figure 4 ).
  • the tube distribution magazine and the fork constituting the gripping and positioning means constitute two moving assemblies which must be perfectly aligned at the time of transfer of an empty tube, so that the settings are difficult to achieve.
  • a third disadvantage lies in the fact that according to the state of the art, the positioning of the fork under the effect of the evolution of the diameter of the coil, creates a variation of forces that it is necessary to compensate in using control means that are difficult to adjust.
  • a fourth disadvantage lies in the fact that when the coil is deposited in its evacuation means, in the form of a ramp or the like, it tends to systematically cross. Indeed, the coils tend to slip asymmetrically since they generally have a straight edge and a rounded edge, which tends to accentuate the sliding relative to the right edge, causing a pivoting effect. Thus when the evacuation means is constituted by a ramp, the coil can not roll to the bottom of the ramp.
  • the dispensing means is constituted by an assembly comprising, on the one hand, a fixed magazine and, on the other hand, a movable arm.
  • the distribution means is therefore not entirely fixed.
  • the object of the invention is to remedy these various disadvantages in a simple, safe, effective and rational manner.
  • One of the problems that the invention proposes to solve is to allow the end of the wire to wind when the coil is disposed on the evacuation means and to facilitate the positioning adjustments of the dispensing means of the empty tubular supports. relative to the gripping and positioning means of said supports for the transfer operation.
  • Another problem to be solved by the invention is to perfectly control the contact force between the coil in formation and the receiving cylinder must be perfectly controlled to obtain a quality winding.
  • the support thereof is in a position close to the vertical, that is to say that the point of rotation of the fork constituting gripper and grip member of the coil, is substantially above the center of gravity of said coil. It turns out that the weight of the coil creates only a small component affecting the pressure force, so that the variation of the weight during production will create a small variation of this contact force. It is therefore possible to simplify the means for controlling this contact force.
  • the present invention provides a means to solve the problem of ensuring that the full reel is completely evacuated without risk of jamming.
  • the fork constituting the gripping and positioning means of the reel is equipped with means for retaining the tube, during its release, and then accompanying it at the beginning of its movement. evacuation during the rotation of said fork towards the gripping point of a new empty tube to the distribution system.
  • the fork rotates to the point of removal of the coil towards the discharge means, and releases the coil at this point. Then, continuing its rotation to the distribution system empty tubes, the fork retains and accompanies, through the appendages arranged for this purpose, the coil during its evacuation. This action has the effect of realigning the tube relative to the ramp and to give the coil an initial speed sufficient for it to be evacuated without being braked by friction.
  • the removal of the coil can be done, either by marking a pause in the movement of the fork, or without marking downtime, that is to say in the continuity of its movement.
  • the textile machine illustrated, figure 5 is of the type comprising, in known manner, at least one cylinder (1) for receiving the wire (2) subjected to a back-and-forth system (3) for forming the coil (B) on a tubular support ( 4).
  • the tubular support (4) is rotatably mounted in articulated gripping and positioning means, constituted in particular by pivoting arms ( 5), forming a fork.
  • the empty tubular supports (4) are mounted in a device (6) acting as a distributor.
  • the coils (B) are evacuated via at least one ramp (7) inclined downwards, from substantially the winding area. Note that the coils can be evacuated by other means.
  • the motorized receiving cylinder (1) is positioned in front of the tubular support (4) in a position of winding.
  • the formation of the reel (B) takes place at the rear of the cylinder (1), with respect to the arrival of the wire.
  • the wire (2) arrives from below the receiving cylinder (1).
  • the direction of rotation of the coil (B) is opposite to that of the conventional arrangement indicated in the introductory part of the description and illustrated in FIGS. Figures 1, 2, 3, and 4 .
  • the fork forming a gripping member and positioning of the reel rotates to a depositing position. At this position, the fork (5) releases the reel (B) which rolls along the discharge ramp (7), the end of the wire tending to wind up and no longer unwind ( figure 7 ).
  • the distributor magazine (6) of the tubular elements (4) is fixed, and positioned angularly above the winding zone.
  • the fork (5) is arranged to continue its movement and come to grip a tubular support (4) in the distribution magazine (6) ( figure 8 ).
  • the fork then pivots in the opposite direction to position the empty tube at the level of the winding zone, behind the receiving cylinder (1) ( figure 9 ).
  • the winding process can then resume, by transferring the wire from the suction nozzle to the empty tube.
  • the ends of the arms are arranged in the form of clamps (9) to release at will the tubular support elements (4) after the winding operation.
  • appendages (10) are mounted at the end of the gripping arms to straighten and align the coil when released at level of the evacuation ramp. These appendages (10) have a tendency to retain and then accompany the support element (4) receiving the coil during the pivoting of the fork (5) in the direction of the dispenser magazine (6) to seize again a tubular element, so that the The coil assembly does not tend to cross the discharge ramp (7) and is driven with sufficient initial speed to ensure complete descent.
  • the pivot axis (11) of the arms (5) is located above the receiving cylinder (1) and the discharge ramp (7).
  • the arms (5) pivot according to the arrow (F) to enter the tubular elements (4) positioned in the magazine (6) and according to the arrow (F1) to position the tubular element seized at the winding zone .
  • Figures 6, 7, 8 and 9 show the main phases of operation of the device according to the invention.
