Definitions
- the invention relates to the technical sector of textile machines, in particular excavation operations.
- the invention finds in particular an application in the field of textile machines, wiring, twisting of threads, texturing, and more generally of thread transformation.
- the problem in this type of textile machinery is notably to be able to remove and unload the tabular supports on which the spools of thread are formed with a view to replacing them with empty tabular supports and relaunching the production of a new spool.
- Patent GB 1024615 of 1963, discloses by way of example, a device intended to be integrated into a winder, the principle of which foreshadows that still used today. This device is individual, that is to say, integrated into each winding position.
- US Patent 3344594 of 1964, discloses a means of performing the function for machines having an alignment of working positions arranged side by side, such as wiring machines, twisting or textaration. It is a mobile robot moving along the machine, capable of positioning opposite caving positions, and embedding means such as arms, grippers, at locations containing empty tubes, controlled by an automaton, and therefore capable of carrying out the digging operation.
- the invention relates to a textile machine of the type comprising that, in a manner perfectly known to a person skilled in the art, at least one motorized receiving cylinder (R) of thread (F) subject to a reciprocating system (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 tabular supports are pre-positioned in a distributor magazine (M).
- the finished coils (B) are discharged by a ramp (Ra) or other means.
- FIGS. 1, 2, 3 and 4 showing an example of a device and a known principle of operation of this type of machine for the digging operation.
- the coil (B) is finished, the wire (F) is cut in a suction (figure 1). Then, the coil (B) is released 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 side opposite to the arrival of the wire (F) (figure 2)
- the handling 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) to be recovered later.
- the distributor of tabular supports (M) then pivots to place another tabular support in the fork which therefore has gripping and positioning means (P) ( Figure 3).
- the fork (P) applies, by displacement or rotation, again the tabular 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 mobile assemblies which it is necessary to align perfectly when transferring an empty tube, so that the adjustments are difficult.
- a third drawback is that, according to the state of the art, the positioning of the fork under the effect of the change in the diameter of the coil, creates a variation in forces which it is necessary to compensate for. using control means that are difficult to adjust.
- a fourth drawback resides in the fact that when the coil is deposited in its discharge means, in the form of a ramp or the like, it tends to systematically cross. Indeed, the coils tend to slide asymmetrically since they generally have a straight edge and a rounded edge, which tends to accentuate the sliding relative to the straight edge, causing a pivoting effect. Thus when the evacuation means is constituted by a ramp, the coil cannot roll to the bottom of the ramp.
- the object of the invention is to remedy these various drawbacks in a simple, safe, efficient and rational manner.
- One of the problems which the invention proposes to solve is therefore to allow the end of the wire to be wound when the reel is placed on the discharge means.
- a winding device has been designed and developed, equipped with means for placing and removing spools of thread in a machine of the type described above and according to which the receiving cylinder and the tabular support in the winding position are positioned in space, according to a defined direction of rotation, so that the wire reaches the point of contact passing under the receiving cylinder, and is wound over the tabular support, and the formation of the coil and its release movement towards the discharge means are in a direction opposite to the arrival of the wire.
- the winding direction is such that the coil thread tends to wind when the coil rolls on said discharge ramp.
- the other problem which the invention proposes to solve is to facilitate the adjustments of the positioning of the means for distributing the empty tabular supports with respect to the means for gripping and positioning of said supports for the transfer operation.
- the invention provides an arrangement in which this means of distribution is fixed.
- the fork constituting the means for gripping and positioning the tabular support is positioned in space and articulated, so that the movement of the support, due to the magnification of the coil during formation, then its release to the point where it is deposited on the evacuation means, then its displacement to the point of gripping of a new empty tube in the distribution device, is arranged on the same simple path, preferably circular, and in that order.
- the return of the empty tube, from the distributor to the point of contact on the receiving cylinder takes place along the same path in the opposite direction, the full coil deposited on the outward journey being, in the meantime, discharged .
- the other problem which the invention proposes to solve 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 gripper of the coil, is located substantially above the center of gravity of said coil.
- the present invention provides a means of solving the problem which consists in ensuring that the full reel is completely removed without risk of jamming.
- the fork constituting the means for gripping and positioning the reel is equipped with means intended to retain the tube, when it is released, then to accompany it at the start of its movement of evacuation during rotation of said fork to the gripping point of a new empty tube to the distribution system.
- the fork rotates to the point of depositing the reel towards the discharge means, and releases the reel at this point. Then, continuing its rotation towards the distribution system of the empty tubes, the fork retains and then accompanies, by means of appendages arranged for this purpose, the coil during its evacuation. This action has the effect of realigning the tube with respect to the ramp and giving the coil an initial speed sufficient for it to be evacuated without being braked by friction.
- the reel can be removed, either by marking a stopping time in the movement of the fork, or without stopping time, that is to say in the continuity of its movement.
- FIG. 5 is a view showing the main elements of the device for placing and removing spools of thread, according to the characteristics of the invention in an application to a textile machine.
- FIGS 6, 7, 8 and 9 are schematic views of different phases of the digging principle according to the invention.
- the textile machine illustrated, FIG. 5, is of the type comprising that, in known manner, at least one cylinder (1) for receiving the thread (2) subjected to a reciprocating system (3) for forming the spool ( B) on a tabular support (4).
- the tabular support (4) is rotatably mounted in articulated gripping and positioning means, constituted in particular by pivoting arms ( 5), forming a fork.
- the empty tabular supports (4) are mounted in a device (6) acting as a distributor.
- the coils (B) are evacuated by means of at least one ramp (7) inclined in the downward direction, from substantially the winding zone. Note that the coils can be removed by other means.
- the motorized receiving cylinder (1) is positioned in front of the tabular support (4) in the position of winding.
- the reel (B) is formed at the rear of the cylinder (1), relative 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. 1, 2, 3, and 4.
- the distributor magazine (6) of the tabular 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 tabular support (4) in the distribution store (6) ( Figure 8).
- the fork then pivots in the opposite direction to position the empty tube at the winding area, behind the receiving cylinder (1) ( Figure 9).
- the winding process can then resume, thanks to the transfer of the wire from the suction nozzle to the empty tube.
- the ends of the arms are arranged in the form of clamps (9) to free the tabular support elements (4) at will after the winding operation.
- appendages (10) are mounted at the end of the gripping arms to straighten and align the spool when it is released at the level of the evacuation ramp. These appendages (10) tend to retain and then accompany the support element (4) receiving the coil during the pivoting of the fork (5) in the direction of the distributor magazine (6) in order to grasp a tubular element again, so that the 'the entire reel does not tend to get across the discharge ramp (7), and is animated with an initial speed sufficient 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 grasp the tabular elements (4) positioned in the magazine (6) and according to the arrow (FI) to position the tubular element grasped at the winding zone .
- FIGS. 6, 7, 8 and 9 show the main operating phases of the device according to the invention.
