Definitions

  • the present invention relates to a method and a device for preparing the opening of a coil consisting of a strip of flexible material wound in superimposed turns and comprising an upper turn whose free end is fixed on the turn which is directly below it, said coil being disposed on a support axis and comprising two parallel sides.
  • the upper coil of the coil is covered with a protective strip, made of a material which may be different from that constituting the coil; by upper turn of the coil is meant in the following description this possible protective strip as well as the first turn or turns of the coil.
  • An object of the invention is therefore to propose a method compatible with known coil opening methods and making it possible to ensure that the turn situated directly below the last cut turn is absolutely intact.
  • Another object of the invention is to propose a device for preparing the opening of a reel which can be adapted to a device for opening a known reel and keeping intact the turn situated directly below the last turn. cut.
  • Figure 1 shows a cutting preparation device 1 disposed above a coil 2 fixed to a support axis (not shown) and comprising a plurality of turns 20 including in particular an upper turn 21 whose front end is glued on the turn which is directly below it in order to close the coil.
  • the coil 2 can also be defined by its two lateral surfaces forming its two parallel sides 22.
  • the device 1 firstly comprises a first actuator 10, for example a hydraulic or pneumatic cylinder, the outer cylinder of which is fixed to a machine frame 3 by known means 30.
  • a first actuator 10 for example a hydraulic or pneumatic cylinder, the outer cylinder of which is fixed to a machine frame 3 by known means 30.
  • the means 30 allow the device 1 to move in order to bring it above the coil 2 to prepare its opening and then retract said device so that it does not interfere with the subsequent operations to be carried out. on the spool. It can be considered that during the operation of the preparation device 1 the external body of the actuator 10, respectively the cylinder of the jack, is fixed and immobile relative to the coil 2.
  • the actuator 10 comprises a movable rod 11, capable of move in one direction or the other, in a direction perpendicular to the support axis of the coil and directed towards said support axis.
  • the end of the movable rod 11 of the jack 10 is fixed to a first support 12 extending parallel to the support axis of the coil, preferably behind the coil 2, as can be seen particularly in FIG. 2.
  • Guide means 12A prevent rotation of the support 12 in order to keep the support 12 always aligned with the support axis of the coil.
  • a baluster 12B maintains a blade support 13 at a determined vertical distance fixed to the support 12.
  • a flat blade 13A can slide inside the blade support 13, in a direction parallel to the support axis of the coil 2, passing from a retracted position as seen in FIG. 2 to an advanced position in the direction of the coil 2, as seen in FIG. 4.
  • the advance movement or removal of the flat blade 13A is obtained by a second motion actuator 13B, pneumatic or hydraulic included in the blade support 13.
  • a double set of braces 15 each consisting of a pair bars 15A and 15B is arranged on each of the sides of the support 14 parallel to the sides of the coil 2 and below said support.
  • a first central axis 16 connects each of the crosspieces 15 by a preferably central position of each of the bars 15A and 15B, allowing said bars to pivot around said first central axis.
  • each of the bars 15A is fixed, each on an opposite face of the support 14, by means of a second axis 16A, passing through said support and allowing said bars to pivot simultaneously around said second axis.
  • the upper ends of the bars 15B are likewise connected by a third axis 16B, said axis being sliding in a direction perpendicular to the axis of the coil 2 as well as to the direction of movement of the first movable rod 11, in a borehole 14A through and extending in the direction of the second axis 16A, of the support 14.
  • the end of the support 14 distal from that fixed to the support 12 supports a third actuator 17, which can also be a pneumatic or hydraulic cylinder, comprising a second rod mobile 17A, fixed at its end to the axis 16B and able to move said axis parallel to itself in the bore 14A, in the direction defined above.
  • the lower ends of each of the bars 15A and of each of the bars 15B are connected by two fourth axes 16C, said axes not being pivotable relative to the bars 15A or to the bars 15B.
  • the two axes 16C each support a friction lining 18 connecting together and being arranged below the lower ends of the two opposite bars 15A, respectively of the two opposite bars 15B.
  • the friction linings 18 are therefore parallel to the support axis of the coil 2 and are each covered, on their face facing the coil 2, with a coating having a high coefficient of friction with respect to the material constituting the turns 20 of the coil, for example rubber.
  • a coating having a high coefficient of friction with respect to the material constituting the turns 20 of the coil for example rubber.
  • the contact surfaces of said coatings are rounded, longitudinal ridges can be provided on these surfaces.
  • the spacing between the two opposite cross-pieces 15, respectively the length of the friction linings 18, is at least equal to the width of the strip of material constituting the coil 2.
  • the movable rod 17A of the actuator 17 is in the retracted position, respectively the axis 16B is in a position remote from the axis 16A.
  • the actuator 17 By activating the actuator 17 so as to bring the axis 16B closer to the axis 16A, one obtains by a chisel effect of the braces 15 a bringing together of the lower ends of the bars 15A and 15B of each brace, respectively a bringing together of the two fittings of friction 18.
  • the two friction linings 18 lower slightly towards the coil 2.
  • each of the bars 15A pivots around the axis 16A
  • each bars 15B pivots in the opposite direction around the axis 16B
  • the ends of each of the bars respectively the contact surfaces of the linings 18 pivot slightly against one another.
  • a cutting device 4 in particular comprising a cutting blade 40 and which is arranged in the standby position.
  • the coil 2 is stationary on its support axis.
  • the means 30, for bringing the preparation device 1 are actuated to position said device near the upper turn 21, the two friction linings 18 slightly above of the coil 21, being parallel to the axis of the coil and not being in contact with the coil 21 while the blade 13A is positioned a few tenths of a mm below the upper surface of the upper coil 21.
  • the distance relative to said upper surface to which the flat blade 13A is disposed essentially depends on the thickness of the strip of material constituting the upper turn 21.
  • this starting position of the device 1 relative to the coil 2 can be done manually or automatically by means of a position detector device (not shown, but can be of the same type as that described more bottom next to the second embodiment of the device) coupled to a control unit 9, capable of determining that the device is positioned correctly above the turn 21 and that the flat blade 13A is positioned correctly with respect to said turn.
  • a position detector device not shown, but can be of the same type as that described more bottom next to the second embodiment of the device
  • the actuator 17 is actuated, which brings the axis 16B closer to the axis 16A causing the movements described above, ie a descent of the contact surfaces of the friction linings 18 in contact and pressing on the turn 21, and a bringing together of the two said linings accompanied by their pivoting movement.
  • These movements of the two linings 18 were sufficient, as soon as they came into contact with the upper coil 21, to pinch it slightly and then to lift it and create an arch 21A between the two linings 18, as seen in the figure 3.
  • This arch 21A on the coil 21 is therefore caused by the combination of the movements described, firstly a strong contact between the linings 18 and two distant surfaces of the coil 21, then by the bringing together and pivoting of the two linings which , given the high coefficient of friction of their coating, do not slip on the coil 21.
  • the actuator 17 is stopped, while the actuator 13B is activated in order to advance the flat blade 13A so that its end passes into the space included under the arch 21A, ie between the upper turn 21 and the turns of the lower layers 20.
  • the flat blade 13A is held in this position and the cutting device 4, respect ively the cutting blade 40, is brought between the bars of the spider 15, directly above the arch 21.
  • the means by which the blade 40 is actuated are not part of the preparation device according to the invention, but of one of the cutting devices described in one of the patents mentioned in the introduction.
  • the blade 40 can thus cut the arch 21A, respectively the upper turn 21 by sinking only as far as the flat blade 13A against which it finally comes into abutment.
  • the flat blade 13A has protected the first of the turns of the lower layers 20 which therefore cannot be started by the blade 40.
  • the end of the flat blade 13A penetrating between two turns of the coil 2 is of rounded shape so as not to hurt the turns.
  • the cutting blade 40 is removed, then the flat blade 13A by the actuator 13B, then the actuator 10 is again actuated in order to separate the linings 18 from the coil 21 and the means 30 move the device 1 away from the coil 2.
  • the means by which the upper end of the coil 21 is gripped in order to be brought to the manufacturing machine are also not described here since they are in the patents cited above.
  • the cutting is only carried out on the upper turn 21, in fact the arch 21A is formed by several of the upper turns of the coil, possibly with the protective strip mentioned previously, so that several turns are then cut.
  • the device for preparing the opening of a reel has been described above according to a preferred embodiment, it is obvious that variants of this embodiment can be provided; in particular it is not at all necessary that the device 1 be placed above the coil 2 in a vertical position, in fact it could be oriented at any angle relative to the center of the coil, provided that the relative angles of the various movements described are preserved.
  • the actuators described as being pneumatic or hydraulic cylinders could be made up of any element capable of producing the movements described.
  • Another embodiment of the means making it possible to bring the two axes 16A and 16B closer together could also be provided, for example a rod having two threaded sections in opposite directions, rotated by the actuator 17, each of the threaded sections passing through a threaded hole of the axis 16A, respectively of the axis 16B.
  • the central axis 16 has been described as being arranged in a central position of each of the bars 15A and 15B; in fact it could be shifted so as to have a movement of the linings 18 multiplied or divided with respect to the movement of approximation of the two axes 16A and 16B.
  • the support 14 supporting the crossbars 15 and the friction linings 18 is independent of the support 12 supporting the blade 13A, so that it can be moved away from the coil 2 after the blade 13A has been inserted in the spool in order to leave, if necessary, sufficient space for the cutting device 4.
  • FIGS. 5 to 8 Another embodiment of a device for preparing the opening of a reel is shown in FIGS. 5 to 8.
  • a coil 2 comprising a plurality of turns 20 and in particular an upper turn 21 is fixed on a support axis not shown.
  • the preparation device here consists of a blade holder device 5, a position detection device 6 and a control unit 9; it can be completed with a blowing device 7.
  • These different elements are shown separated from each other in order to make the figures clearer, but it is obvious that they are part of the same assembly and are connected to a common plate comprising displacement means capable of bringing said elements into an action position close to the spool 2.
  • the blade-holding device 5 comprises a flat blade 50, absolutely similar to the flat blade 13A described above, and being able, like it, to assume a retracted position , as in FIG. 6, or an advanced position, as in FIG.
  • a position detection device 6 of said upper turn consisting of a another actuator 60 equipped with a touch element 61, preferably a caster, which, positioned first clearly above the upper turn 21, as shown in FIG. 5, then lowers the touch finger 61 until 'it comes into contact with the upper turn 21, as seen in Figure 7.
  • This position is raised by the control unit 9 which can then activate the actuator 52 in order to place the flat blade 50 a few tenths of mm below the dimension corresponding to the upper surface of the upper turn 21.
  • the distance from said upper surface on which the flat blade 50 is disposed depends essentially on the thickness of the strip of material. u constituting the coil 2. Taking into account that the turns of the coil 2 are not too tight, the blade 50 is gently introduced under the upper turn 21, preferably for the reason indicated above with regard to the first embodiment, under at least two of the upper turns. This advance movement of the flat blade 50 can be carried out while the coil 2 is stationary or when the latter is driven by a slow rotational movement in the direction going from the caster 61 towards the flat blade 50.
  • the direction of this rotational movement is opposite to that of the normal unwinding of the reel so that, during this rotational movement, the flat blade 50 tends to be pushed upward by the spiral winding of the turns of the reel .
  • the roller 61 can continue to detect the position of the upper layer 21 in order to correct the position of the flat blade 50 in the case where the coil 2 is not exactly circular.
  • the spool is stopped in the event that it has been rotated and, as for the first embodiment described, a cutting device 4 is approached in order to cut the turns arranged at- above the flat blade 50, cutting only these, the cutting movement being limited by the flat blade 50. As shown in FIG.
  • the preparation device can be supplemented by a blowing device 7, essentially composed a blowing nozzle 70, which projects a jet of pressurized air directly above the flat blade 50, in the direction of the coil 2, in order to help lift the upper turns, thus facilitating the penetration of the flat blade 50.
  • the detection means 6 can also be designed so as not to come into contact with the upper turn 21, for example consist of optical detection means.
  • a preparation device makes it possible, in cooperation with a device for cutting and gripping the upper turns of a coil, to obtain a strip intact material for later use, said strip could not have been damaged by the cutting device.
