Definitions

  • the present invention relates to a device for ensuring the drawing and winding of thermoplastic son, especially glass.
  • reinforcing glass son results from a complex industrial process which consists of obtaining threads from threads of molten glass flowing through the orifices of dies. These nets are drawn as continuous filaments, and then these filaments are gathered together in locks, which are then collected in the form of windings.
  • the windings are in the form of coils, or more precisely still in the form of "cakes", these cakes being intended more particularly for applications related to reinforcement.
  • the cake form is made using winders, which as their name suggests, are responsible for winding at very high speed (about 10 to 50 meters per second) the glass son that were previously sized .
  • These winders provide the drawing and the winding of these filaments and the operating parameters of these winders condition with those of the die the dimensional characteristics of the yarn, in particular the title expressed in tex (the tex being the weight in grams of 1000 meters fiber or yarn).
  • the speed of the winder winding member is enslaved so as to ensure a linear winding speed of the winder. constant wire although its angular velocity varies, this speed control being achieved by reducing the speed of rotation of the spindle which supports the cake as a function of the increase in its diameter.
  • Another important parameter which determines the obtaining of a cake of optimal quality consists in its ability to be easily unrolled, without the presence of loops, parasitic nodes, with limitation of friction. This ability to unwind is determined by the nature of the construction law (which determines the magnification of the cake) that has been generated by the winder during cake formation. This law of construction incorporates many parameters, one of the most important is the crosstalk report, often called RC and the title of the wire.
  • the winders of the prior art which essentially consist of a frame generally positioned below a die, this frame supporting the creasing device and at least one movable spindle in rotation, this pin being adapted on the one hand, to generate the cake and on the other hand, to support the latter, generate a kinematics or a particular race to the wire from the combination of two movements: a first movement that prints a primary race to the wire and a second movement that prints a secondary race to the wire, the first and second movements are generally applied by a single body with combined movement which is more generally known as the device of encroisure which is conventionally a propeller or any other equivalent device such as in particular a helical grooved wheel, which can describe all or part of the length cake.
  • the strands of threads are movable with the crimping device and the spindle supporting the cake is fixed in translation and mobile in rotation.
  • the secondary stroke C2 is obtained by an axial translation of the spindle supporting the cake.
  • the thread locks and the creasing device are stationary along the axis of horizontal translation (but rotatable) and the spindle supporting the cake is movable in translation and rotation.
  • a first solution to take into account these unwinding problems is to change the crest ratio is the ratio between the winding speed and the speed of flapping of the primary motion.
  • this parameter By modifying the value of this parameter, it is possible to modify the winding angle of the wires on the coil, which has the effect of acting directly on the arrangement of the turns, we can thus modulate this parameter to obtain the better compromise of quality of reel hold necessary during the various manipulations of the method of manufacture and quality of reeling of the wire which is essential to its use during the various process of transformation of the wire.
  • drying cakes after winding is an important and delicate part of the process because it seeks to evacuate a maximum of moisture in a minimum of time and this without degradation of products, for this it is necessary to allow water trapped at heart of the winding to evacuate easily arranging the turns so as to create evacuation channels that will allow better ventilation of the winding.
  • the present invention therefore aims to take the aforementioned problems by proposing improvements made to the creasing device.
  • the winder according to the invention is according to claim 1.
  • a winder 1 according to the invention illustrated in figure 1 , it comprises a metal frame 2 obtained by a technique of mechanically welded metal elements previously machined or available as standard commercially.
  • This frame 2 essentially comprises a substantially rectangular base 3 resting on legs judiciously placed so as to correspond to the jig or the spacing of the forks of a pallet truck or a similar handling device to facilitate the implementation of this winder in a fibering position.
  • this closed structure shaped cabinet is provided with control devices and of control necessary for the various regulations of the various components which will be described later in this description, of networks, hydraulic, electrical, compressed air, and other fluids necessary for the operation of said organs
  • This cylinder 5 On the closed structure 4 cooperates a cylinder 5 which protrudes laterally.
  • This cylinder 5 is rotatably mounted about an axis of rotation (called the third axis of rotation) and is held within one of the walls of the closed structure by means of a plurality of guide members ( ball crown, ball slide for example). It is also planned to motorize this barrel 5 so that it can describe and index a plurality of angular positions relative to the frame 2, during the winding of the cakes.
  • this barrel 5 constitutes a pin support assembly.
  • the barrel 5 has two pins 6, 7, in diametrically opposite positions (one could conceive a barrel having only one pin [if there is only one pin, it does not there is no need barrel but it is not possible to do the automatic restart] or on the contrary a barrel with at least three, four pins or more, depending on the size available and the capabilities of the die positioned in upstream).
  • the barrel 5 makes it possible to bring a spindle previously unloaded and provided with at least one blank sleeve (within the meaning of the invention, a sleeve is a support made of plastic or cardboard which is intended to receive winding yarn or cake) in the winding position and another spindle having its full cuffs unloading position by rotations of 180 ° (if the barrel has two pins, as shown in the examples).
  • a sleeve is a support made of plastic or cardboard which is intended to receive winding yarn or cake
  • Each of the pins 6, 7 integral with the barrel 5 constitutes a rotating assembly adapted to wind the wire on a sleeve previously introduced on the sleeve or the pin nose.
  • This winding is carried out according to a first axis of rotation substantially parallel to the axis of rotation of the barrel 5 relative to the structure of the frame 2.
  • the spindle can be adapted to be able to perform a back-and-forth stroke parallel to the first axis of rotation (secondary stroke movement C2), in the opposite case, it is the crease system that will be of the same way (secondary stroke movement C2).
  • This movement back and forth is caused by a motorized actuator linear movement (ball screw for example) secured on the one hand, the cylinder or the frame and on the other hand, the body of the spindle.
  • the number of propellers 8 will be adapted accordingly, and the propeller support shaft will comprise a propeller train, the number of which will be equal to the number of cakes that you want.
  • the rotational movement of the helix is translated at the wire by a movement of oscillations or beats whose amplitude and frequency are adjustable according to the values of the desired crest ratio.
  • the frequency is determined according to the speed of rotation and the amplitude is a function of the geometry of the helix.
  • FIG. 1 Other devices not shown on the figure 1 can be considered as a substitute for the propeller. It may be a wheel provided with at least one groove, this groove being adapted to position and guide at least one wire, said wheel being rotatable about a second axis substantially parallel to the first axis.
  • the crimping device 8 performs a so-called primary stroke movement or C1 and operates in speed regulation and possibly position with the back and forth of the pin 6 or 7 which constitutes the so-called secondary travel movement C2, according to the embodiment variant illustrated in FIG. figure 3 , moving spindle 6 or 7 in a reciprocating motion in a direction parallel to its axis of rotation being performed by an actuator M2 meshing with a kinematic chain with the shaft spindle support.
  • the crisscrossing device 8 is mounted on a motorized rotary axis by means of a motor M1, which provides the first reciprocating movement of the wick, called the primary movement or C1.
  • This assembly cooperates by means of a kinematic chain 14 of the screw-nut or similar type set in motion by means of an actuator M2 (engine for example) making it possible to print to this assembly a translation movement along an axis substantially parallel to the axis of rotation of the crimping device so as to give the latter an additional back and forth movement called secondary movement or C2.
  • the actuator M2 is provided with an additional control member 12 of the servomotor type servo-controlled position and / or speed for continuously controlling the movement kinematics (speed and / or position) of the actuator responsible for printing the C2 secondary back-and-forth movement.
  • the primary and secondary strokes of the winder 1 are decoupled with the aid of the control member 12.
  • This additional control member 12 offers possibilities for adjusting and optimizing the arrangement of the turns that can solve the problems of holding cakes at a given crosstalk ratio meeting a need for unwinding or a need for drying.
  • the variations of this control member may also make it possible to increase the amount of son deposited at the ends of the cakes in order to promote their filling.
  • a pull-thread 9 is a set of wire drive which is used during the restart, the restart being a transitional phase prior to a winding phase.
  • the wire is drawn by a motorized roller train with smooth walls or with reliefs (the wires are brought to operating conditions that are compatible with the setting of the wires in the spindle nose when starting the winding phase ).
  • the winder comprises at least one rotary ejector 10 and at least one right ejector 11, these project laterally with respect to the closed structure 2 and in line with the cylinder 5.
  • the rotary ejector 10 or the retraction device is constituted by an articulated arm at one of its ends at the closed structure of the frame 2, its free end is adapted to grip and move the wires between a first position in wherein the yarns are engaged with the crimping device 8 of the wire (the helix for example) and a second position in which the wires are retracted with respect to said crimping device 8.
  • the angular movement of the rotary ejector 10 is performed during the change of spindle 6 or 7 (pivoting 180 ° of the barrel 5).
  • the right ejector 11 is as its name suggests a substantially straight arm. Projecting laterally as the rotary ejector 10 with respect to a side wall of the closed structure of the frame 2, it can occupy two positions: a rest position in which it is set back from the path of the wire, and a working position in which it holds the wire above the pin nose 6 or 7 when raising. This working position is also occupied during a transfer operation (rotation of the barrel, and passage of a pin with wrapped cakes, to a pin with empty cuffs).
  • wire 8 helix for example
  • a cleaning member not visible in the figures of said positioning device by spraying a fluid under pressure.
  • the barrel 5 makes an angular correction by rotation and indexing of its angular position around its axis so as to move the spindle away.
  • active "- that where the winding of the device - the periphery of the device for positioning and guiding the wire, so as to maintain a fixed geometry.
  • the winding is active, the movements of primary stroke and secondary stroke are controlled by the steering device 12 to comply with the law of construction.
  • the speed of the secondary stroke remained constant at a value V2 as well as the crest ratio K. (the crest ratio K being defined as the ratio of the speed of the spindle to the speed of the crease device V bat ).
  • V thread drawing speed
