Definitions

  • the object of the present invention is to improve the control devices making it possible to automate a winding operation so that the torch or the winding produced have the least possible winding faults.
  • the present invention relates to a device for controlling a slicing operation on a reel of an elongated product, comprising drive means for rotating the reel at a predetermined speed, and means for trenching which are arranged opposite the reel and which themselves comprise means for guiding the elongated product which are driven so as to move parallel to the axis of the reel alternately in one direction or the other, characterized in that said means for slicing comprises a carriage movable in translation parallel to the axis of the reel and subjected to the action of displacement means, a guide arm pivotally mounted on the carriage around an axis perpendicular to that of the reel, and guide members which give the arm an orientation corresponding to the approach angle of the product, and in that the device also comprises automatic control means which give the means for moving the carriage a speed controlled by the angle of approach of the product so that this angle keeps a constant value during each stroke of the slicing operation.
  • the device makes it possible to adjust the speed of advance of the slicing trolley according to the section of the product to be wound up.
  • the feed speed may vary under the influence of an analog inductive sensor which tends to regulate the feed speed so as to maintain the approach angle of the product at a constant value.
  • the slicing device comprises a base 1 which is fixed and which is placed at a predetermined distance from a reel of which a reel 2 is seen to fig. 1.
  • This reel is mounted on an axis (not shown) which is oriented perpendicular to the plane of the drawing. It is rotated by means which are not shown but which make it possible to print on the reel a determined speed of rotation, for example a speed remaining constant throughout the winding operation.
  • the purpose of this operation is to form on the reel 2 from an elongated product 3 which can be for example an electric cable, but also a plastic pipe, or a flexible profile, a torch 4 formed by a number of turns deposited side by side on the reel 2 and layers of turns stacked one on the other as seen in fig.
  • the slicing device comprises first of all inside the base 1 a carriage 4 which consists of an armature plate 5 and two pairs of rollers 6 mounted one at a above the other on one side of the plate 5. Each of these pairs of rollers 6 cooperates with a slide 7 having the shape of a rail arranged horizontally and oriented perpendicular to the plane of the drawing. These rails are fixed to the base by wheelbases 7a. To the plate 5 is further fixed a drive lug 8 with which is associated a nut 9. A drive screw 10 pivoted by means which are not shown but arranged parallel to the slides 7 is coupled to a pulley 11 which 'a motor 12 can rotate by means of a belt 13.
  • a pivot pin 21 is arranged under the slide 19 exactly between two guide rollers 20 located at the front of the slide.
  • a guide arm 22 oriented towards the drum of the reel 2, pivots on the journal 21. At its end it carries a guide tube 23 ensuring the deposition of the elongated product 3 directly on the winding being formed throughout the duration of the operation.
  • the guide means are balanced by a counterweight 24 located at the rear of the guide slide 19.
  • the guide arm 22 extends behind its pin 21 by a tail 25. The latter cooperates with a holding means 26 fixed in the bottom of the slide 19 and consisting of a base pierced with a vertical hole and a spring urging a ball engaged in a depression formed in the upper surface of the tail 25.
  • this tail 25 can be blocked by a finger 27 which cooperates with a jack 28 fixed under the slide 19.
  • the jack 28 makes it possible to rigidly block the arm 22 in a fixed orientation relative to the slide 19, while , that the holding device 26 retains the arm in the same position but allows a deflection if the guide tube 23 is subjected to a lateral force.
  • the trenching device described is also equipped with two kinds of sensors. Stroke limit sensors are constituted by two stops 29 fixed under the upper wall of the base 1 at locations corresponding to the maximum displacements of the pillar 15 along the screw 10 in one direction and in the other. These stops cooperating with an inductive sensor 30 which is fixed to the pillar 15 and which consequently can emit a control signal when it is in line with one or the other of the stops 29.
  • the stops 29 can be adjustable, which allows to vary the stroke of the slicing device.
  • a second detector device is also provided.
  • This is the analog type inductive sensor 31 which is mounted on one side of the slide 19 at a certain distance from the pivot axis of the pin 21 and which cooperates with a movable member 32 formed in the form of a fixed pallet. to the arm 22 in the vicinity of its pivot axis and extending in the direction of the sensor 31.
  • Figs. 3a, 3b and 3c show how the sensor 31 and the pallet 32 make it possible to identify the orientation of the guide arm 22 and therefore the angle of approach of the elongated product 3 on the winding.
  • the approach angle shape or with respect to a plane perpendicular to this axis. The position of fig.
  • 3a corresponds to a situation where the guide arm 22 is located exactly in a plane perpendicular to the axis of the barrel 2 and where the pin 21 is distant from the side of the last turn deposited on the barrel at a distance equal to half the width of the profile of the product 3.
  • the angle of approach is zero and when the arm 22 is in this position, its tail 25 is held by the ball of the device 26. If, from this position, the device is too fast, i.e. that the speed of movement of the carriage 5 is too high, the arm 22 will necessarily take the position of FIG. 3b.
  • the pallet 32 will therefore move away from the sensor 31 so that the orientation signal will vary.
  • the sensor 31 being an analog sensor, the magnitude of the transmitted signal will vary in proportion to the deviation of the arm 22 from its normal position.
  • the detectors described thus make it possible to carry out an automatic and high-precision control of the entire slicing operation.
  • the circuit diagram is visible in fig. 4.
  • the motor 12 which is a direct current motor whose speed of rotation depends on the voltage at the control terminals. This voltage comes from an output 33 of the control circuit 34 after being amplified in an amplifier 35.
  • the signals input of circuit 34 are as follows: firstly at 36 between a DC voltage whose value depends on the speed of rotation of the reel 2.
  • a tachometric dynamo 37 forms a DC voltage proportional to this speed of rotation and this voltage is divided into a potentiometer 38 in a ratio which can be arbitrarily fixed and which will depend for example on the width of the profile of the product to be wound.
  • the direct voltage at the entry point 36 determines, as a first approximation, the speed of rotation of the motor 12.
  • This amplified voltage in the amplifier 39 is led to a summator 40 in which it is added or subtracted from it a value of voltage which is determined by the signal supplied by the detector 31.
  • the value of this signal is amplified in an amplifier 41, then in the selective inverter 42 and it is maintained at the input polarity or changed sign according to the direction in which turns the motor 12, i.e. depending on the direction in which the slicing carriage moves.
  • the output signal from the selective inverter 42 is supplied to the adder 40.
  • the result of the addition is then supplied to the selective inverter 43 which performs exactly the same functions as the inverter 42 and which supplies the amplifier 35.
  • the selective inverters 42 and 43 are controlled by the control device 44 which reverses the position of the switches 45 and 46 as a function of the signals emitted by the sensor 30 when the latter is opposite the stops 29.
  • a very simple and precise operating device is thus produced which ensures perfectly regular turn-to-turn deposition of an elongated profile such as a plastic tube or a cable.
  • the jack 28 is controlled, so that the arm 22 is necessarily brought back and locked in the position corresponding to the zero approach angle, thanks to the cooperation between the jack 28 and the finger 27.
