Definitions

  • the present invention relates to an automatic method for slicing a flexible elongated product, such as for example a cable or a tube, on a motorized reel provided with a guide and a member ensuring the relative relative movement, of a first sensor for measuring the relative position of the drum guide X, of a second sensor for measuring the loading angle formed by the incidental rectilinear part of the product with a plane perpendicular to the axis of rotation of the drum and an electronic data entry, storage and calculation unit.
  • a first sensor for measuring the relative position of the drum guide X
  • a second sensor for measuring the loading angle formed by the incidental rectilinear part of the product with a plane perpendicular to the axis of rotation of the drum and an electronic data entry, storage and calculation unit.
  • a device for the automatic slicing of a flexible elongated product such as for example a cable or a tube
  • this device comprising a motorized reel provided with a guide and a member ensuring the relative relative movement, d a first sensor for measuring the relative position of the reel guide X, a second sensor for measuring the loading angle and an electronic device for entering and storing data calculation.
  • drums consist of an at least approximately cylindrical barrel bounded by two approximately planar and parallel surfaces, perpendicular to the axis of the cylinder and designated by the usual term of cheeks.
  • the loading operation that is to say winding of a cable, a tube or other product on the reel consists in rotating the latter on itself around its axis and, in the case which we interested in guiding the product in its external part to the drum so that the winding is carried out regularly in turns as contiguous as possible. This is called trancannage.
  • the reel In the case of systems for industrial use, the reel is driven by a motor.
  • the guidance of the product to be wound up which we will designate by the term cable in the rest of the text, is carried out either manually by an operator, or by a mechanical guidance device.
  • Currently known automatic trenching systems can be divided into two groups: fixed winders with mobile guide, mobile (self-cutting) winders with fixed guide.
  • the relative translational movement is provided by a device comprising at least one adjustable speed variator which makes correspond to the rotation of the winding reel a predetermined (programmed) movement of the guide, proportional to the fixed pitch.
  • a device for reversing the direction of movement generally using stops assumes the function of reversing the guide when the cable reaches a cheek.
  • the operator tries to obtain a winding as precise as possible, that is to say without spacing of the turns and without overlapping, by manually correcting the position of the guide and / or the pitch, the aim being to lay the cable against the previous turn by forcing it slightly against it.
  • the programmed advance slicing does not (in many cases) allow obtaining a perfectly regular winding as desired by the cable manufacturer.
  • a slicing device as defined in the preamble and having the above faults is described in the European patent application published under No. 43 368.
  • the present invention proposes to overcome the above drawbacks.
  • the method according to the invention comprises the characteristics stated in claim 1, and the device according to the invention comprises the characteristics stated in claim 5.
  • This clamping angle conditions the installation of the cable: if it is too strong the whorl in formation risks overlapping the previous one, if it is too weak or negative, the whorl deviates from the previous one.
  • the helix angle not being constant for the various reasons stated above, it follows that the loading angle must be constantly adapted, in order to keep as constant as possible the value of the clamping angle.
  • the object of the present invention is to provide a solution to this problem, namely to maintain the clamping angle by a constant value.
  • the difficulty consists in defining the set value of this position, since its aim is to achieve a very specific condition for a quantity (the clamping angle) which cannot be measured directly.
  • this angle is the difference between the helix angle and the loading angle. These two angles must therefore be determined.
  • the helix angle p as shown in FIG. 1 is, for drawing purposes, significantly larger than life.
  • the desired clamping angle y is normally greater than the helix angle ⁇ .
  • Fig. 2 schematically shows by way of example for understanding an embodiment of the device according to the present invention, plan view:
  • a reel 20 rotates about its axis, driven by a motorized device not shown.
  • This drive device is provided with a first not shown sensor (absolute or incremental) of the usual type, potentiometer or optical encoder for example, supplying in electrical form a signal enabling the angular position ⁇ of the reel to be known.
  • This same sensor will supply the rotation speed information if necessary: value derived from the position in the case of a potentiometer measurement, pulse frequency in the case of an incremental sensor.
  • This guide is movable along the axis X ′, X ′′, this axis being parallel to the axis of rotation of the reel:
  • a conventional motorized drive device of known type ensures its movement.
  • device (not shown) is additionally provided with a second sensor (potentiometer or optical encoder for example) intended to supply an analog or digital signal corresponding to the displacement of the guide along its axis of translation X ′, X ′′, in absolute value or incremental.
  • a third sensor, secured to an arm 23 carrying an oscillating roller 22, makes it possible to know the loading angle a, that is to say the angle formed by the cable 24 relative to the perpendicular to the axis of rotation of the reel 20:
  • the arm supporting this roller 22 has for example as point of rotation that of the two guides 21 which precedes it. It is recalled by a spring or even for example by a pneumatic cylinder, in order to keep it in contact with the cable.
  • the roller In the case of a pneumatic cylinder, the roller can thus be automatically released to the left during the operation of placing the cable leader, then pressed into the measurement position in a timely manner.
  • the sensor defining the loading angle a can be a coaxial potentiometer at the point of oscillation of the arm, but it can just as easily be of the inductive, capacitive type or consist of a binary encoder. It may possibly be of the linear type, coupled to the spring or to the pneumatic return piston.
  • the roller 22 can finally be provided with a fourth rotation sensor (for example of the incremental type) in order to know the speed of travel of the cable and incidentally the loaded length, by counting or integration of the pulses.
  • a fourth rotation sensor for example of the incremental type
  • the scroll measurement sensor can also just as easily be independent of the roller 22, the corresponding signal being able to be supplied by the device existing on the production machine.
  • This last configuration although more expensive given the mass of material to be moved, has the substantial advantage of a fixed position and direction of the cable as it enters the guide, this position being in the axis d 'a production machine, such as a machine or an extruder.
  • the optimum clamping angle (determined experimentally) is a function of the type of cable, that is to say of its diameter, its rigidity and the coefficient of friction of its surface.
  • this angle can be understood, for a given cable, between two extremes, one corresponding to the risk of overlapping, the other to the risk of non-juxtaposition of the turns. This therefore results in a certain margin of tolerance.
  • the error in the measurement to the loading angle may not be negli- g eable, even if the rocker arm is relatively long, the cable may change abruptly out of guide 21.
  • this spring can be replaced by a pneumatic cylinder or any other conventional device capable of ensuring a longitudinal displacement parallel to the axis X 'X "of translation of the reel.
  • the device is applied to a portion considered to be reasonably straight of the cable lying between the guides 21 and the point of tangency to the drum 25, the distance between the guides 21 and the drum being able to be increased without disadvantage to a sufficient value.
  • the relative abscissa x 2 reel guide being measured by the translation sensor, that of the point of tangency can thus be determined by calculation at each instant, by means of a microprocessor for example. It is then enough to memorize these successive values in correlation with those of the rotation ⁇ of the reel to know, by call successive in memory, the position of the previous turn.
  • the cable loading angle during cutting is generally negative.
  • the distance h varies somewhat depending on the filling state and the diameter of the drum. Since this variation is small, it is generally not necessary to take it into account, although the corrective trigonometric calculation could be carried out by the microprocessor if necessary, the winding diameter being able to be determined as described below.
  • the microprocessor can give, by simple calculation, the value of the helix angle at the point considered according to the relationship: if one accepts to replace the differential increases by limited increases.
  • Ax is the difference between 2 successive values x n and x n + 1 calculated for the abscissa of the tangency point corresponding to 2 successive values ⁇ n andQ n + 1 of the angular position of the reel stored, ⁇ l corresponding to the length of cable having passed in contact with the roller 22 during the same interval, namely:
  • the microprocessor can calculate the length of the coiled cable itself without using an ad-hoc sensor.
  • ah ⁇ ⁇ ⁇ 1 • D where n and the number of turns (determined from ⁇ ), D the diameter of the drum.
  • I r ⁇ ⁇ . ⁇ 2 (D + d), where d is the cable diameter, a value that the microprocessor can easily determine from the average displacement (step) for each turn of the reel. And so on.
  • the value is obtained in the same way, individually for each layer, the microprocessor memorizing the number of coiled layers, that is to say the number of reversals of the direction of the helix.
  • This value can be entered as a setpoint y o by manual insertion at the control panel. It can also be memorized for the various types and diameters of cables and automatically recalled by the processor.
  • the servo could also take a as the set value, the measured value being that given by the corresponding sensor.
  • a quick examination of the algorithms however makes it possible to realize that the function is identical, the bases of computation being in fact the same.
  • the helix angle is obtained by analysis of the image observed by a TV camera arranged perpendicular to the axis of rotation of the reel.
  • Hanging the cable leader is a manual operation.
  • the winding of the first turn is to be considered as an operation which is not a servo, but rather a programming, the cable simply having to be wound against the cheek, circularly in its first part.
  • the winding will then take place at a pitch fixed by the supposedly known diameter of the cable or by manual control of the movement.
  • the enslavement that is to say its engagement, will either be decided by the operator, or automatic, for example after a rotation of a fraction of a turn of the reel.
  • the memorization of the parameters x, a and ⁇ being carried out from the start of the rotation, the system will be able to intervene immediately, taking into account in particular the anomaly of propeller caused by the birth of the first turn since we know its position .
  • the diameter of the cable is necessarily known to the microprocessor at that time, either because this value was manually entered by the operator, or because a sensor was provided for the purposes of positioning the spacing of the guides 21, either because the microprocessor has it itself calculated from the average of the differences of the successive values of the translation at each turn of the reel: no mean propeller.
  • Fig. shows as an example for understanding a simplified diagram of the device.
  • the device is also at least provided with a control unit 51 consisting of at least the interfaces necessary for the reception of signals from the angle and position sensors, including the analog-digital converters - for reading the potentiometers corresponding to the angle and to the abscissa x, of a device making it possible to introduce and / or correct the set value of the clamping angle, of a microprocessor and / or of an arithmetic unit for the processing of these data and their storage in memory according to an adequate program (software), of a digital-analog converter providing the set value of the relative abscissa x of the displacement by guide-reel translation and of an amplifier servo 52 for controlling the motor 53 ensuring said movement.
  • a control unit 51 consisting of at least the interfaces necessary for the reception of signals from the angle and position sensors, including the analog-digital converters - for reading the potentiometers corresponding to the angle and to the abscissa x, of a device making it possible to introduce and
  • the processor can be equipped, if necessary, with a device 54 allowing the display and / or recording of the various values that it receives and / or calculates: helix angle, loading angle, clamping angle, diameter of the product, loading speed, loaded length, number of turns and / or layers, speed of rotation of the drum, etc.
  • the servo amplifier may, if a low-cost economic solution is desired, be replaced by two comparators having as signals input the setpoint value from the computer and the value of the actual position measured by the sensor.
  • the output signals of these comparators whose switching thresholds will be slightly offset, will serve as a control order with two relays, each ensuring a direction of operation of a simple three-phase motor, this intermittently, that is to say say by small successive displacements.
  • the solution is obviously significantly less expensive than that consisting of a regulator and a DC motor, especially when it is an already existing installation to be transformed.
