Definitions

  • the present invention relates to a device for flaring a elongated element, for example a tube, obtained by extruding a material synthetic or by any other continuous production process.
  • the device for making the torch is associated with a device suitable for placing a ligature in several places around the turns assemblies forming the torch, so as to keep it in shape.
  • the flaring device Since the elongated element is obtained by an extrusion process in continuous, the flaring device must be designed in such a way that when a torch is complete and the elongated element has been cut, means are provided for receiving the cut end to form a new torch, without the need to stop the process extrusion.
  • a shaping device is described in patent EP-0,426,614. This device provides two flaring devices arranged each at one end of a pivoting arm. When a first torch is finished, the swivel arm rocks bringing the other torch device opposite the means for supplying the elongated element, while the packaging of the first torch can be finished and it left the device during the making the next torch.
  • Such a device is difficult to use when the dimensions of the torch becomes important, either when the elongated element put in torch is very long, either when this element has a large diameter. In these cases, the masses and volumes to be used movement during pivoting of the movable arm becomes very important and the dimensions of the device become prohibitive, especially in height, given the torch diameters.
  • a first object of the invention is to propose a device for making torches of a slender element provided with means allowing to supply a second means of flaring as soon as a length of the elongated element has been assembled on a first means of torch, said device being of limited size.
  • a second object of the invention is to propose a setting device in torches fitted with an automatic cutting device for the first torch then subsequent torches.
  • a third object of the invention is to propose a setting device in torches fitted with an automatic ligating device for the first torch then the following torches.
  • yet another object of the invention is to propose a device in torches provided with automatic control means making it possible to automatically switch from making a torch to making the torch next.
  • Figure 1 shows the downstream end of a production line 1 of an extruded tube 2. It is shown schematically there: the end in downstream of a cooling tank 10, a withdrawal device, for example a track 11, a torch making device 3 preceded by a unit of cutting 4 and a ligation unit 5. A completed torch 20 is in the process to be evacuated by evacuation means 6. The device for making torches 3 is controlled by a control unit 7, which may be specific to the torch-making device 3 or which can be integrated into a general control of the production line 1.
  • FIG. 2 is a top view of some of the elements of the Figure 1.
  • the torch making device 3 consists of two stations A and B for making a torch, the two stations A and B being arranged side by side in a direction perpendicular to the X axis schematically showing the longitudinal axis of the production line 1.
  • the torch making device 3 comprises in particular two pairs of guide means 30 arranged perpendicular to the previously mentioned X axis and extending symmetrically on either side of said axis X.
  • the guide means 30 can be rails or slides arranged on the floor.
  • a fixed frame 300 is mounted across the guide means 30, being aligned on the axis X of the production line. Frame 300 cannot move along guide means 30.
  • Two movable frames 31 are mounted on the means respective guide 30, being able to move along said means of guiding between a spread or open position, as shown for example by the frame 31 of the position A moved away from the frame 30, and a close position or closed, as shown for example by the frame 31 of station B close to the frame 30.
  • Motorized drive means not shown in the figures ensure the movements described above of the movable frames 31 of the stations A and B.
  • Sliding or sliding means represented at 310 on the Figure 4, adapted to the type of guide means 30 allow the displacement of the frames 31 of stations A and B.
  • the fixed frame 300 carries a first flange 32 on each of its faces directed towards a movable frame 31.
  • Each flange 32 is mounted independently in free rotation on a bearing 320, the two so-called bearings being aligned along the same axis, perpendicular to the X axis and mounted one behind the other on the central portion of the fixed frame 300.
  • FIG. 3 which represents a flange 32 seen from the front, we see that it is not made up of a solid disc but of several circular crown segments 321, extending radially, regularly arranged around an outer perimeter of a central disc 322.
  • the figure shows that the flange 32 comprises six segments 321, but it could include a different number.
  • a first requirement of the device is that free spaces remain between the segments 321, in order to be able to carry out the ligating operations which will be described later, while a second requirement is that the segments provide sufficient mechanical strength to support laterally the torch being made.
  • the outer diameter written out by segments 321, respectively the diameter outside of flange 32 is slightly larger than the maximum diameter admissible torch.
  • the flanges 32 of stations A and B are identical. Each can therefore be rotated on its own bearing 320, independently of the other.
  • each movable frame 31 carries a second flange 33 facing a flange 32.
  • Each flange 33 is mounted on its movable frame 31 by a bearing 330, each of said flange being able to be driven independently by rotation by its own motorized drive means 331.
  • each flange 33 is visible on the Figure 4, which shows a flange 33 front view.
  • the flanges 33 are composed of circular crown segments 332 fixed on a central disc 333.
  • the outside diameter exinscribed by the segments 332 is less than the diameter of a torch.
  • Each segment 332 carries a movable support element 34 consisting here of a segment internal support 340 and a lateral support segment 341.
  • the movable element 34 is able to be moved radially over a certain distance along the segment 332 by an actuator 35. It can be seen in FIG. 4 that the segments internal support 340 form portions of a circle corresponding to the inside diameter of the torch to be formed.
  • FIG. 5 shows a preferred way in which the movable element 34 is mounted on the segment 332 and is actuated by the actuator 35.
  • each actuator 35 comprises an endless screw 350 rising parallel to the plane of the corresponding segment 332 and extending radially.
  • the end of each screw 350 distal from the central disc 333 is provided with a bearing, not shown, fixed to the end of segment 332 corresponding.
  • Means, not shown but known in the art, housed in the central disc 333 are able to simultaneously rotate all the screws 350 of a flange 33.
  • each support segment interior 340 connected to the corresponding segment 332 is provided with means for guides 342 capable of guiding the internal support segment 340 so that that it is able to move radially along segment 332, while remaining perpendicular to said segment.
  • Guide means 342 include a through hole 343 through which passes the worm 350 freely.
  • the actuator 35 then comprises a block 351, also provided with guide means along segment 332 and comprising in in addition to a tapped hole 352 corresponding to the thread of the screw 350. A movement of rotation of the screw 350 in one direction or the other therefore causes a radial movement, in one direction or the other of the block 351.
  • a cylinder 353 is fixed by its cylinder to the inner support segment 340, the piston rod 354 being connected by two links 355 and 356 on the one hand to a portion of the segment internal support 340 close to the guide means 342 and on the other hand to block 351, the articulations between these different elements being pivoting.
  • the piston rod 354 and the links 355 and 356 are shown on the is in an intermediate position, for the correct understanding of the operation of the device.
  • the assembly formed by the block 351, the link 356 and 355 and the support segment interior 340 forms a rigid block.
  • a screw 350 actuation in one direction or in the other therefore causes a displacement of the interior support segment 340 one way or the other, that is, considering all of the support segments 340 actuated simultaneously, an increase or a reduction of the inside diameter of the circle exinscribed to these support segments interiors forming the internal diameter of the torch to be formed.
  • actuation cylinders 353, i.e. a displacement of the piston rods 354 to the left according to FIG. 5 brings the inner support segments closer together 340 relative to blocks 351, which remain fixed relative to the segment 332, thus causing a slight decrease in the diameter exinscribed by the internal support segments 340.
  • Actuation in opposite directions of the cylinders 353 returns the interior support segments 340 to their initial position, respectively to the set exinscribed diameter. Such a function allows temporarily decrease the diameter excribed by the segments slightly internal support 340, so that a completed torch can be released as we will see later.
  • the hydraulic or pneumatic circuit of the cylinders 353 is designed in such a way that it is necessary to apply pressure to lower the inner support segments 340.
  • the means of adjusting the diameter written out by the segments interiors 340 can obviously be designed differently from what is described here; for example the screw 350 could be replaced by means to rack, cylinder means or more simply segment 332 could have a certain number of determined positions on which the block 351 could be directly fixed.
  • the means of lowering temporary interior support segments 340 could also be designed differently and be made for example of cams.
  • the position of the support segment lateral 341 is adjustable along the inner support segment 340.
  • Means 344 fasteners allow each lateral support segment 341 to be fixed on fixing positions determined along each interior support segment 340, thus making it possible to adjust the width of the torch to be formed.
  • each flange 33 is provided with a locking shaft 36, one end of which is fixed to the disc central 333 correspondent.
  • the other end of the shafts 36 is provided with a fixing means 360, suitable for fixing in a corresponding fixing means 361 of the central disc 322 of the flanges 32.
  • An actuating means 362 allows the opening or closing of the fixing means to be controlled 360 so as to fix together or separate the two flanges 32 and 33.
  • the means fixing 360 and 361 cooperate to lock together the flanges 32 and 33, respectively to support the lateral forces exerted by the torch in training on these two flanges.
  • the right portion of the same figure representing station A shows that the two flanges 32 and 33 have been separated.
  • means drive 37 are provided to rotate the flanges 32 of each station A and B.
  • These means can consist, for example, of minus a training bar including a training bar 370 in projection on the central disc 333 of each flange 33 as well as a bar driven 371 projecting from the central disc 322 of each flange 32.
  • the flange 33 driven in rotation by its motorized drive means 331, rotates the flange 32 by means 37 which have just been described.
  • busbars 370, 371 may be provided on each set of flanges 32, 33.
  • the torch-making device 3 which has just been described is of preferably supplemented with a cutting device 4 as seen particularly in FIG. 2.
  • This cutting device is essentially similar to other known devices except that it is able to move on guide means 40 which are longer than usual, so as to be able to supply successively either station A on the left or station B of right.
  • the cutting device 4 can be completed with a cut 41, able to cut the tube when a first torch is full on a first post.
  • the control means 7 are capable of adjusting the travel of cutting according to the adjusted position of the lateral support segments 341 on the inner support segments 340, thereby defining the width of the torch to form.
  • a ligating unit 5, particularly visible in FIG. 2, can usefully complete the system.
  • This ligature unit 5 is also essentially similar to other known devices except that it is able to move on longer guide means 50 that usually, in order to be able to supply successively either the station A on the left, that is, post B on the right.
  • the ligature unit 5 is composed of a carriage 51, able to move on the guide means 50, said carriage carrying two laying arms 52 able to move apart, as shown in the figure or to approach so that their ends are in contact, under the action of an actuator 53.
  • the unit further comprises a unit of unwinding of a link 54, able to circulate the link in the arms 52 when they are brought together and stretch this bond which comes to be welded by a device welding 55.
  • the arms 52 can be raised so that the ligating unit 5 goes from one torch-making station to another.
  • the control unit 7 is also able to adjust the position of the carriage 51 on the guide means 50 in depending on the position of the lateral support segments 341, so that the welding device 55 operates over a central portion of the width of the formed torch.
  • the evacuation means are made up, according to one embodiment, of two pairs of support rollers 60 and 61, each roller being mounted on its own lifting means. Each pair of rollers can be followed by a ramp 62 leading to guides 63 where the completed torches are optionally stored, being ready to be removed by known means. So we see that by means 6 described as above, the torches 20 finished are evacuated downstream from the production line, and therefore do not encumber lateral regions of the production line or of the confection device torches.
  • the control unit 7 can be specific to the manufacturing device of torches or integrated into the control unit of the production line.
  • the control unit includes a microprocessor unit equipped with an adequate management and control program for the making torches. Sensors placed in the appropriate places on the torch-making device indicates the state, position, speed, etc. of the element with which they are associated, the control unit then actuating the various drives or actuators described.
  • each of the inner support segments 340 has been adjusted by so that the diameter of the circle written by said segments corresponds to the desired internal diameter for the torch.
  • the position of lateral support segments 341 has been adjusted according to the desired width for the torch.
  • the arms 52 of the ligating device 5 have been raised and the device of cutting 4 is brought so as to be able to start the first turn near a flange 32 or 33 of station B.
  • the ligating device is activated at least once in order to make up minus a ligature before activating the cutting device 41 of the cutting 4.
  • the second station was closed and prepared as indicated above for the first post.
  • the cutting device 4 is quickly brought in front of the second post where the second torch is made in the same way as described above.
  • the ligating device 5 performs a few ligatures on the perimeter of the torch to keep it assembled, following what the rollers 61 and 61 are raised to come into contact with the surface outer device of the completed torch to support it. Ways 35 allowing the diameter exinscribed by the support segments 340 are activated so that said segments support are released from the torch.
  • the fixing means 360 and 361 are triggered, making it possible to move aside the movable frame 31, respectively the flange 33, until the inner support segments 340 and the fixing bar 36 are entirely disengaged from the center of the torch. By then lowering the support roller 61, the torch begins to roll on the ramp 62 while being guided by the guide means 63.
  • the cutting means are not not provided on the cutting device 4 but are associated with the end of production line 1, immediately following withdrawer 11.
  • the reference 12 of Figure 1 denotes this cutting device.
  • This variant can be used when the time required to set up the cutting 4 in front of the new substation to be supplied is too large relatively at line production speed.
  • the tube can form one or several sinusoids on the ground, in the space separating the cutting device 12 of the cutting device 4, guide means 13 can be provided to guide the end of the tube in this space.
