Definitions

  • the present invention relates to the winding of large diameter cables on spools according to the preamble of claim 1 (known from EP-A-43368).
  • large diameter cable is meant insulated electrical cables with an outside diameter greater than 10 mm.
  • the diameter of the cables does not exceed 60 mm.
  • these cables are produced in segments as long as possible and they are wound on spools whose dimensions often reach several meters in diameter.
  • the winders supporting these coils and driving them in rotation are large mass devices requiring for their drive powerful and bulky motors.
  • Patent CH 576,392 describes a winder of this kind in which the cutting trolley is supported by a rail parallel to the axis of the spool holder and the spool holder itself has two independent uprights, one of the 'other and likely to move on rails also parallel to the same axis. It is thus possible to carry out either cutting operations in which the cutting carriage and consequently the cable guide move parallel to the axis of the coil over the entire length of the latter, or so-called self-cutting operations in which the cutting carriage remains fixed and it is the whole of the reel support which moves in translation in front of the cutting carriage.
  • the cutting trolley is movable in front of the spool holder and its drive is connected to the spool drive so that the speed of the cutting is proportional to the speed of the winding.
  • fig. 1 schematically shows a coil 1 on which a cable 2 is being deposited turn by turn.
  • the coil 1 comprises a cylindrical barrel 3 and two end flanges 4 and 5 also called cheeks having the form of discs.
  • the cable 2 is hooked by its end into a hole 6 formed in the barrel 3 of the coil 1.
  • the winding of the cable on the drum of the coil does not consist of successive parallel helices but forms a series of irregular curves.
  • the cable arrival strand designated by 7
  • the delay angle is maintained at a suitable angle called the delay angle and designated in FIG. 1 by r.
  • the angle of the strand 7 relative to a plane perpendicular to the axis of the coil must be modified and during the deposition of the last turn of a layer this angle must be brought to zero.
  • the delay angle is reversed, since during the deposition of a layer forming from left to right, this angle must be inverted compared to the value it has during the deposition of a layer forming from right to left.
  • EP 0 043 368 discloses a winder for large diameter cables which is equipped with an automatic control and command device.
  • This device comprises a detector which indicates, at each turn of the reel, the moment when the deflection which marks the start of a turn is at the location where the cable arrives on the winding, so as to move the reel by relative to the cable guide and thus maintain a delay angle of predetermined and constant value.
  • the object of the present invention is to create a device for automatically controlling a cutting operation capable of equipping large winders capable of supporting and driving reels intended to receive long lengths of cables of greater diameter. at 10 mm.
  • the subject of the present invention is an automatic control device for a cutting operation, capable of controlling the formation of a winding with successive turns and layers by a cable coming from a production or processing line, on the drum of a reel to which the cable is attached, the reel (1) being rotated about its axis on a support (10, 12), and the cable (2) passing through a cable guide (23, 24 ) which is movable relative to the reel support (10, 12) in the direction of said axis and which guides the cable with a predetermined delay angle towards a location for depositing a turn, characterized in that it com carries a turn formation detector (28, 29), comprising projection means (28, 29, 31), a reception surface (33) and detector means (34) placed on said reception surface and arranged to transmit an electrical signal representative of an image of the silhouette of a predetermined area of the winding comprising said location for depositing the cable, image formed on the receiving surface (33) by the projection means, in that it comprises furthermore separate drive means (x, y, z) capable of controlling the

  • FIGS. 2 and 3 We will begin by briefly describing the winding installation shown in FIGS. 2 and 3.
  • the barrel 3 and the left flange 5 of the coil 1 are visible in section through a plane perpendicular to the axis of the coil in FIG. 2.
  • the flange 5 is supported by a pinole 8 (fig. 3) carried itself by a bearing 9 integral with the left upright 10 of the winder.
  • the upper cross member 11 of the winding machine (fig. 2) extends parallel to the axis of the reel 1 and guides the upper end of the upright 12 which includes a bearing 13 itself guiding a pinole 14 supporting the right flange 4 of the reel 1.
  • the two uprights 10 and 12 of the winder rest on bases 15 and 16, provided with rollers 17 which roll on two parallel rails 18.
  • the rollers 17 are linked to drive means making it possible to move the whole of the winder back and forth on the rails 18, while means for driving the reel 1 (not shown) rotate one of the pinoles 8 or 14 provided with coupling elements to the corresponding flange of the reel.
  • the drive means of the coil are capable of rotating the latter around its axis at a constant or variable speed depending on conditions which can be predetermined. Thus, for example, the drive of the coil can take place at constant resistance torque.
  • a cutting support which comprises a rigid vertical upright 19 provided with guide means shown in the drawing by a dovetail groove 20 extending vertically and capable of guiding a horizontal arm 21 which can thus be moved vertically from top to bottom and bottom to top on the upright 19.
  • This support arm 21 itself has in its upper face a guide groove 22 in which slides a cutting carriage 23.
  • the latter carries two rollers cylindrical with vertical axes 24 arranged parallel to one another at such a distance from each other that the strand 7 of the cable 2 is guided closely between these two rollers.
  • Driving means not shown make it possible to move the carriage 23 from left to right and from right to left parallel to the axis of the coil 1 in front of the latter, the strand 7 of the cable being further guided in the height direction.
  • the rollers 25 are supported at their ends by uprights 26 which rest on the support arm 21.
  • Another support arm 27 secured to the horizontal base 21 makes it possible to fix above this base a camera 28, the principle of the optical system is shown schematically in FIG. 4.
  • This camera 28 has a lens 29 whose axis of the optical system is oriented horizontally and perpendicular to the axis of the coil 1.
  • the height of the axis of the objective 29 can be chosen at will and as will be seen later, it is controlled so that this axis is tangent to the last complete layer of the winding formed on the coil 1.
  • the axis of the objective 29 a direction different from that which has just been defined, in particular a slightly inclined direction, the rule of the tangency to the last complete layer of the winding being however a general rule
  • the described winding installation comprises a light ramp 30 arranged vertically opposite the camera 28 but on the other side of the coil.
  • this light ramp has the effect of projecting in a direction perpendicular to the axis of the coil the image of the silhouette of the winding, i.e. the image we obtain if we cut the winding being formed by a vertical plane passing through the axis of the coil.
  • This device is an optical device of a type known per se, in particular a device of the brand Reticon sold by the company EG & G. Inc. in Wellesley (Mass. USA).
  • This device called “image detection system” includes a lens 29 of the zoom type making it possible to vary the focal length and the magnification of the device.
  • the image formed by the objective is reflected by a 45 ° mirror 31 and projected as a real image onto a reception surface 33.
  • This reception surface 33 is materialized by a grid 34 which, in the embodiment described, is square and made up of a series of photodetector cells. These cells, for example photosensitive diodes are connected in a circuit materialized by a microprocessor MP.
  • a grid 34 formed of 1024 cells distributed over a square of 32 cells on the side allows detection sufficiently fine to meet the operating conditions.
  • the ramp 30 projects onto the objective 29 the shadow of the winding silhouette.
  • the objective 29 itself makes it possible to choose the size of the area of the winding which will be projected onto the grid 34 and it has been observed in particular that a magnification such as the area of the winding which is projected onto the grid 34 has the appearance shown in FIG. 5, was a suitable magnification.
  • FIG. 5 we see on the grid 34 formed of 1024 photodetector cells the image of the silhouette of a part of the winding comprising four turns of cables designated by A, B.
  • the cells are adjusted so that their state (conductive or non-conductive) changes according to whether they are exposed to the radiation from the ramp 30 where, for them, the ramp 30 is masked by the winding.
  • the 1024 cells will be divided into series each corresponding to a column so that by suitable switching of the electronic circuit MP, it will be possible, at any time, to perform a scanning operation during which all of the detector elements of the grid 34 will be explored successively, for example by successive columns.
  • This exploration will give rise to an electrical signal composed of a series of pulses in binary code giving for each element of the grid 34 its lit or hidden state.
  • the photo-diodes of the grid 34 will be explored by successive series, each series being composed by the elements of the same column.
  • Fig. 5 gives by way of example the result of such an exploration.
  • the 1024 photo-detector elements of the grid 34 are represented in the form of a square matrix numbered by lines and by columns. Each of these elements is designated by the number 35.
  • the image of the silhouette of a predetermined area of the winding as it appears on this grid is clearly represented in this fig. 5.
  • the silhouette of two turns A and B of the last complete layer deposited on the winding is clearly visible in the left part of the image as well as part of the silhouette of a turn C belonging to the same layer.
  • a fourth turn D of the last complete layer is completely embedded in the part of the image for which the elements are in the masked state. Above this complete layer, two turns E and F of the layer being formed appear. As it is visible in the drawing, this layer in formation is formed by successive turns going from right to left, although this may actually correspond to a layer forming from left to right as a result of the reversal of the image.
  • the winding being formed masks on the grid 34 the cells 35 which are on the right and below in FIG. 5, of a limit line G.
  • This line in fact envelops the profiles of the turns A, B, C. F and E.
  • a program element introduced in the microprocessor MP can determine the position on the grid 34, at any time, of the point S of this line corresponding to the vertex of the re-entrant right angle defined by the profiles of the turns B, C and F.
  • the essential characteristics of the detected image is therefore represented by the coordinates Y and X of the point S on the grid 34.
  • the central point of the grid being determined by reference coordinates C1 and C2, the ordinate Y designates the level at which the upper line of the layer formed by the turns A, B, C and D is located, while the abscissa X denotes the position along the X axis of the free edge of the image of the coil F.
  • the electronic circuit can emit control signals which will act on the various drive means that the device comprises, in order to correct the position of the point S determined by the coordinates X and Y and cause it to coincide with the center of the image, c . with the coordinates C1 and C2.
  • FIG. 6 the functional diagram of the control device described and we will now indicate how the result of the analysis of the image formed on the grid 34 at each scanning of the photo-diodes 35 is processed to act on the drive means.
  • the microprocessor MP which receives the information from the various detector means and which supplies the orders to the drive means.
  • a control panel 36 includes a number of control buttons 37 associated with indicator lamps 38 making it possible to put the device in the desired state so that the various control programs can run.
  • the different drive means are represented by the boxes 39 marked x, y, z and! respectively.
  • the marked box! is an alarm signal and draws the attention of the supervisory staff when a situation not foreseen by one of the programs arises.
  • the drive means marked z is a motor which acts on the cutting trolley 23 already described previously in relation to FIG. 2.
  • This motor can for example drive a pinion 40 in engagement with a rack 41 carried by the base 21.
  • the latter moves vertically on the upright 19 of the cutting device.
  • the control motor z makes it possible to move the two guide cylinders 24 in the horizontal direction relative to the camera 28
  • the rack and pinion gear 40, 41 is also equipped with a position detector which by a line 42 supplies the circuit MP with information on the instantaneous position of the cylinders 24 between which the cable passes relative to the base 21 and consequently to camera 28.
  • the drive motor acts therein in a manner which is not shown in detail in FIG. 6 on the base 21 to move it along the upright 19.
  • a detector 43 is also associated with it so that, by a line 44, information on the height of the base 21 and therefore of the camera 28, can be transmitted to the circuit MP.
  • the motor x acts on the bases 15 and 16 of the gantry winder and controls the rollers 17 thus causing an overall displacement of the winder on the rails 18.
  • a position mark 45 and a detector incorporated in the control of the rollers 17 make it possible to transmit to the circuit MP by a line 46 information on the instantaneous position of the winder along the rails 18.
  • the motor which rotates the coil 1 is shown diagrammatically in FIG. 6 and designated by 47. Normally, this motor is not directly controlled as a function of the results of the analysis of the image appearing on the grid 34. Indeed, it must meet other conditions. Its speed will be adjusted for example as a function of the resistance that the cable encounters in the line from which it comes and this motor will ensure the rotation of the coil, for example with a constant resistance torque. It can also work at constant speed. However, this motor is associated with an orientation detector shown diagrammatically in FIG. 6.
  • a wheel 48 rotating at the same speed as the coil 1 can be provided with regularly spaced tabs 49, so as to supply signals passing near a position detector 50, these signals being transmitted by a line 51 to the MP circuit in which they reach a counter which thus memorizes the orientation of the coil at all times.
  • the winding operation Before starting the control device, the winding operation must be prepared by first hooking the cable by its end into the opening 6 (fig. 1), this opening being located at one end of the drum 3 which can be the right end or the left end, and the coil being placed so that this opening is on the upper horizontal generator of the barrel.
  • the cutting device i.e. more precisely the base 21 will be placed so that the camera 28 whose axis of the lens 29 is fixed is clearly above the barrel of the coil. As shown in the drawing, this axis is oriented horizontally and perpendicular to the axis of the coil, although different axes can also be chosen. However, any movement of the winder or the base 21 carrying the camera should keep this axis parallel to itself.
  • Another essential adjustment to be made before the device is started consists in adjusting the magnification of the optical system 29 of the camera 28 as a function of the diameter of the cable. It is to allow this adjustment that the camera 28 is equipped with a variable focal length lens 29. The magnification will therefore be adjusted so that the image projected on the grid 34 corresponds in length to approx. 4 turns.
  • the conditions of fig. 5 correspond approximately to real conditions and it can be seen that the line G formed by straight line segments at right angles which limit the excited photo-diodes compared to those which are not gives an analog image of the real silhouette of the profile of the winding.
  • the automatic control device To allow the automatic control device to start, it is first of all necessary to lower the camera 28 and to start a program which brings the upper generator of the drum of the coil to be in the center of the image, c . that the ordinate Y is brought to be equal to the set value C1. This result is obtained by acting on the motor y which moves the base 21. Then, the winder is moved by acting on the motor x so that the image of the flange in the vicinity of which the cable is hung, appears in the center of the grid, i.e. that the abscissa X is equal to C2.
  • the preparation program for the operation of the automatic control device includes the adjustment of the starting position of the carriage 23.
  • the latter must be moved on the base 21 by control of the motor z, and this so that the abscissa Z is equal to zero, or in other words, that the center of the distance between the two rollers 24 coincides with a vertical reference plane which marks the axis of the camera lens 28.
  • the drive motor 47 of the coil 1 can be started.
  • the start of this second turn is immediately detected on the grid 34 by the fact that the abscissa X which locates the free flank of the last turn of the winding (turn F) differs from the value C2.
  • this detection is carried out immediately and depending on the results of the analysis, control signals are sent to either of the motors x or z, or possibly on both engines at the same time.
  • signals can also be sent to the y motor jointly or separately from the signals sent to the x and z motors.
  • one of the important features of the device described is that, depending on the importance or the speed of the variation of the detected image compared to the set image which corresponds to the desired conditions, differentiated control signals acting either on motor x or on motor z will be emitted by the MP circuit.
  • the position of the cutting trolley 23 relative to the axis of the objective 29, i.e. the Z coordinate will be set to correspond to a setpoint giving the desired angle r.
  • this angle is adjusted so as to be zero, then it takes the value of a delay angle determined in accordance with the winding conditions to ensure the regular deposition of the following turns against each other.
  • this angle can be temporarily changed.
  • the control device automatically re-engages the winding control program which runs until the new layer is practically complete and the internal surface of the opposite flange appears. again in the picture.
  • the device described makes it possible to act immediately and to correct the abnormal deviations without, for example, the number of connections to be established and the complication of the scanning circuits reaching uncontrollable values.
  • the basic element of the program consists in the fact that at the time of the formation of a new turn, the point S moves relative to the point of coordinates C1, C2.
