Definitions

  • the invention relates to a method and a system for detecting a cutting defect.
  • the winding of the tie on the reel be regular, that is to say that the tie is wound on the reel in the form of one or more successive layers of turns which are joined or have a minimum of play between them.
  • regular winding in fact ensures the mechanical integrity of the tie and also allows the tie to be unwound with a substantially constant tension of the tie.
  • the tie winding system is provided with a shunting system, which comprises a guide pulley arranged opposite the spool, adapted to control the location of each new turn relative to the turns already deposited on the core of the spool.
  • a shunting system which comprises a guide pulley arranged opposite the spool, adapted to control the location of each new turn relative to the turns already deposited on the core of the spool.
  • the width of the coil which corresponds to the distance between the two flanges, is not always known precisely.
  • the coil is made of molded plastic, there may be significant dimensional variations between two similar coils.
  • the sides may move apart under the pressure of the tie, affecting the filling of the spool.
  • Such a defect can be visually observed by an operator and corrected by changing the dimension of the inversion positions.
  • the document JPH09276932 describes a winding system for winding an optical fiber onto a reel, comprising a motor equipped with a rotary encoder, a ball screw coupled to the motor and to the reel to drive the reel in translation alternately in two winding directions opposite a fixed pulley.
  • the motor changes direction of rotation based on data from proximity sensors arranged on a support, which detect the position of the flanges of the reel.
  • the device further comprises a sensor for detecting the position of the optical fiber, and a control device which controls the direction of rotation of the motor based on a fiber speed signal at the pulley and a winding position signal provided by the encoder.
  • a curve is plotted representing the position of the wire at the time of a change in winding direction, detected by the detector.
  • the presence of a bump indicates excess thickness of the winding at a flange of the reel.
  • the control device adjusts the slicing direction reversal position. This results in a reduction of the hump at the next reversal position.
  • the document JPH08217333 describes a spooling system comprising a sensor for measuring the distance of the axis of the guide pulley from one of the flanges of the reel.
  • the instant of change of spooling direction is determined on the basis of geometric considerations.
  • the spooling direction is reversed when the distance between the wire and the flange is less than half the wire diameter.
  • the document JPH08217330 describes a spooling system in which the speeds of wire feed and winding onto the spool are controlled by means of respective encoders, so as to equalize these two speeds.
  • the documents JP2008001451A And JP2006008310A describe other slicing systems including slicing fault detection systems.
  • One aim of the invention is to design a method for detecting a cutting defect which can be implemented automatically.
  • this detection method must also be compatible with an automatic correction method for the cutting defect.
  • the device for regulating the speed of movement of the link is a puppet comprising a pulley arranged at the end of an arm capable of pivoting around a horizontal axis against the return force of a spring, and in which the measured position is the angular position of the arm of the puppet relative to a vertical axis.
  • the measurement of the position of the regulating device is carried out in a measurement window encompassing each inversion position.
  • the minimum and maximum positions of the control device are determined in each measuring window and deviations between each respective minimum or maximum position and the reference position of the control device are calculated.
  • the device for regulating the speed of movement of the link is a puppet comprising a pulley arranged at the end of an arm capable of pivoting around a horizontal axis against the return force of a spring, and in which the measured position is the angular position of the arm of the puppet relative to a vertical axis.
  • the winder is configured to drive the spool only in rotation, the system comprising an actuator configured to drive the guide pulley in translation along the longitudinal axis.
  • the guide pulley is fixed and the winder includes an actuator configured to drive the spool in rotation and translation relative to the guide pulley.
  • the invention relates to a tie winder comprising a winding system as described above.
  • FIG. 1 is an overview of a system for winding a tie L onto a reel.
  • a system is usually part of a winder, which is a machine whose function is to arrange said tie on a reel, for example after its manufacture or after a test of the tie.
  • the link may be an electrical cable, an optical fiber or a bundle of optical fibers, a mechanical cable, a hydraulic or pneumatic conduit or any other suitable means for carrying a fluid or transmitting energy and/or signals.
  • the coil 1 comprises a cylindrical core 10 intended to receive the link in the form of regularly wound turns, and two flanges 11, 12 intended to retain the link on the core.
  • the coil is secured to a winder (not shown) comprising a motor adapted to drive the coil in rotation along a longitudinal axis X which is the axis of revolution of the cylindrical core 10.
  • the reel may be located at the outlet of a tie production machine, in particular an extrusion line, a tie testing machine, or any other machine through which the tie is passed before being wound onto the reel.
  • the winder may be an integral part of the said machine or be juxtaposed with it.
  • the X axis is located in a horizontal plane, which is usually parallel to the ground plane of the facility in which the tie winding is implemented.
  • the shunting system includes a device for regulating the speed of the link and a link guide pulley.
  • the link speed regulation device is shown in the form of a puppet 3 which comprises an arm 31 which can pivot about an axis perpendicular to the X axis against the return force of a spring (not shown), and a pulley 30 arranged at the end of the arm opposite the pivot axis.
  • axis 31 is collinear with a vertical Z axis, but it can be tilted to one side or the other relative to this axis.
  • the angular position of the arm 31 is adjusted to regulate differences in the running speed of the link.
  • the guide pulley 2 is located between the puppet 3 and the spool 1 on the path of the link.
  • Pulley 2 has the function of bringing the link opposite the core of the coil to guide its winding.
  • the pulley 32 which is arranged upstream of the puppet on the path of the link, makes it possible to increase the locking on the puppet 30 and to keep the entry angle on the puppet constant.
  • Pulley 21 acts as a compensator configured so that the length between the puppet and the traverse system is the same regardless of the position of the guide pulley. Pulley 21 moves along the X axis by half a traverse step at each traverse step.
  • the spool is fixed in translation and the guide pulley is movable in alternating translation along the X axis of the spool.
  • the guide pulley 2 is thus secured to a belt 20.
  • a motor (not shown) moves the belt in alternating translation along the X axis.
  • the guide pulley may be translationally fixed and the spool could be translationally movable (in addition to its rotational movement) along the X axis.
  • the movement of the guide pulley 2 relative to the spool is carried out alternately in both directions, between two inversion positions which are the extreme positions of movement of the guide pulley relative to the spool.
  • Said inversion positions are determined according to the position of the flanges, in order to ensure that the first and last turns of each helical sheet are positioned as close as possible to each flange, so as not to generate hollows in the outer surface of the sheets.
  • the inversion positions can be determined when loading a new coil, by measuring the positions of one of the flanges relative to the other which is considered as the origin of the measurement.
  • the cutting system comprises several sensors, which are usually present in cutting systems on the market and therefore do not need to be specifically added for the implementation of the invention.
  • a first sensor is used to measure the position of the guide pulley 2 relative to the spool 1 along the X axis over time.
  • This sensor can, for example, be an encoder of the motor driving the belt attached to the guide pulley.
  • a second sensor measures the angular position of puppet 3 relative to the Z axis over time.
  • the system further comprises a control unit comprising at least one processor adapted to implement algorithms for calculating a cutting fault.
  • the control unit receives measurement data from the various sensors.
  • the processor determines a deviation between the angular position of the puppet and a reference angular position at each inversion position.
  • the processor detects the formation of a hollow or a hump in the winding.
  • FIG. 2 illustrates the principle of measuring the angular position of the puppet.
  • the x-axis is a time axis.
  • the y-axis represents the position of the guide pulley and the angular position of the puppet (arbitrary units).
  • the triangular graph P2 represents the evolution of the position of the guide pulley as a function of time. This position evolves periodically between two successive inversion positions Pi1 and Pi2, which correspond to the tips of the triangles.
  • Curve P3 represents the evolution of the angular position of the puppet relative to the Z axis over time.
  • the P3r curve represents the evolution of a reference angular position of the puppet relative to the Z axis over time.
  • said reference angular position takes two different constant values during a forward and return movement of the guide pulley between the two inversion positions Pi1, Pi2.
  • the angular position of the puppet is not measured punctually at each inversion position, but in a measurement time window F encompassing each inversion.
  • the reference angular position P3r can be determined as the arithmetic mean of the instantaneous angular positions of the puppet measured when the window is opened during a certain number of measurements (for example 50 measurements) preceding the current measurement, for the same inversion position Pi1 or Pi2. This makes it possible to smooth the measurement and avoid taking into account small disturbances without altering the useful signal linked to the real movement of the puppet.
  • the instantaneous angular position of the puppet is recorded.
  • the minimum p3min and maximum p3max positions in the window F are determined and saved.
  • the deviation ⁇ min incorporates an offset applied to the minimum position p3min to take into account the fact that the puppet has a natural (decreasing) movement upon inversion.
  • This offset is a function of the winding speed of the link.
  • the control unit may comprise a memory in which different predetermined values of the offset to be applied are recorded depending on the winding speed.
  • a hollow is characterized by a smaller winding radius of the link; consequently, for a given rotation speed of the coil, the wound length of link is smaller, which results in a displacement of the pad in the direction of an increase in the deviation ⁇ max.
  • An absolute value of ⁇ max greater than the absolute value of ⁇ min is therefore representative of the formation of a hollow in the winding.
  • a hump is characterized by a larger winding radius of the link; therefore, for a given coil rotation speed, the wound link length is larger, which results in a displacement of the pad in the direction of an increase in the gap ⁇ min.
  • An absolute value of ⁇ max lower than the absolute value of ⁇ min is therefore representative of the formation of a hump in the winding.
  • a scaling error can then be defined as the largest absolute value of the deviations ⁇ max and ⁇ min. In the case where these two deviations have close values, we will favor the detection of a dip because the detection of a dip is more significant than that of a bump, which is biased by the shift that is not determined precisely. Thus, in practice, if the absolute value of ⁇ max is greater than that of ⁇ min, we will assign the value ⁇ max to the scaling error. If the absolute value of ⁇ min is greater than the absolute value of ⁇ max to which is added an offset depending on the winding speed, the value ⁇ min will be assigned to the shunting error. If the absolute values of ⁇ max and ⁇ min are close, the value ⁇ max will be assigned to the shunting error.
  • the invention has the advantage of using a sensor integrated into this control device to detect a cutting fault, without requiring any additional measuring means.
  • the implementation of the cutting fault detection therefore does not require any structural modification of the cutting system and can therefore be carried out at a lower cost.
