Definitions

  • the invention relates to a reel for reels of strips of fibrous, cellulosic, plastic, metallic or other material, of a machine for continuously forming a tubular profile or the like, comprising a metallic framework serving as support for pairs of pins on which rotate the spools, a tape tension regulating device and a tape guiding device towards a gluing machine, then towards the forming machine.
  • Document FR-A-2 585 011 already discloses a reel of reels of strips of fibrous, cellulosic, plastic or other material from a machine for continuously forming a tubular profile.
  • This reel has a metal frame serving to support the coils by means of pairs of pins pivotally mounted on said metal frame.
  • the device for regulating the tension of the belts consists in passing the latter alternately, on rollers maintained at a certain height from the ground and around the rollers of a dolly which, for its part, may be subjected to vertical displacement.
  • the weight of the diabolo and the number of strands formed by the alternating passages of the strips on the different rollers make it possible to determine a constant tension of these said strips.
  • the reel has motor elements for driving the coils.
  • These motor elements consist of variable speed motors actuating drive belts applied against the periphery of the coils.
  • This reel has a certain number of drawbacks essentially coming from the motor elements used to drive the coils. Indeed, it should be noted that the number of bands necessary for the production of a tubular profile is relatively variable and certain reels are capable of unwinding up to forty reels simultaneously. Under these conditions, given the thickness of the wound tube to be produced, each of these bands is driven by a different advance speed. Thus, the strip coming to be wound directly on the mandrel of the forming machine is driven by the slowest speed while the strip, constituting the external layer of the tubular profile and coming to be applied last on the layers of strips beforehand glued, is driven by the fastest speed. This variability in the speed of advance of the bands increases when these bands do not all consist of the same material.
  • each reel on the reel comprises individual motor elements and in particular a drive belt actuated by a variable speed motor. Consequently, these motor elements, used for driving the coils, considerably increase the cost price of the reel.
  • variable speed motors for driving the spindles on which the coils are held.
  • coils whose initial diameter is of the order of one thousand six hundred millimeters and the final diameter, after unwinding of the strip, of the order of eighty millimeters, which represents a ratio from about one to twenty.
  • the variable speed motors usually used have speeds ranging in a ratio ranging from one to ten and are not capable of satisfying the preceding conditions.
  • variable speed motors whose speeds range in a ratio ranging from one to twenty but these motors are particularly bulky and too expensive for such use.
  • the present invention aims to remedy these drawbacks.
  • the invention as characterized in the claims, solves the problem of creating a reel of reels of strips of fibrous, cellulosic, plastic, metallic or other materials, of a continuous forming machine for tubular section or others, comprising a metal framework serving as a support for pairs of pins on which the coils pivot, a device for regulating the tension of the strips and a device for guiding the strips towards a gluing machine, then towards the forming machine, this reel comprising, in addition, for each strip, variable speed drive means for conferring on a strip a forward speed controlled by the speed of advance of this same strip at the output of the regulation device, all of these variable speed drive means being biased by a single variable speed motor.
  • each strip can be driven at a different speed, while using only one motor to drive all of the strips.
  • the latter is of increased reliability, which has the consequence of significantly increasing, on the one hand, the rate of production of the tubular profile and, on the other hand, the quality of the latter.
  • thanks to the reduction in the size of the means for driving a coil it is possible to increase the number of these coils on the reel to finally obtain tubular profiles of greater thickness without thereby increasing the size of the reel.
  • the latter can have an initial diameter, before unwinding, significantly larger compared to the coils usually used until now. This arrangement makes it possible to reduce the frequency of intervention of an operator on the reel for the replacement of empty reels.
  • the reel 1, according to the invention, arranged upstream of a continuous forming machine for tubular section, consists of a metal frame 2 on which are reels 3 of tape 4 of fibrous, cellulosic, metallic material , plastic or others.
  • the number of coils 3 juxtaposed on the metal frame 2 will depend on the number of bands 4 necessary for the production of the tubular profile.
  • Each of these coils 3 is mounted on pins 5, these being provided with individual braking devices of the electro-magnetic, pneumatic, mechanical by tangential friction or other type. These braking devices will have the function of slowing down or stopping each coil 3 individually and, to this end, they may or may not be controlled by the operation of the forming machine.
  • the metal frame 2 of the reel 1 is able to support a second series of reels 6 arranged downstream of the first series of coils 3.
  • a coil 6 arranged in the same plane and supported by pins 7 provided with a braking device equivalent to the previous one. All of these coils 6 are arranged, like the coils 3, in a transverse alignment in the direction of advance of the bands 4.
  • Figure 1 shows a coil 3 in progress.
  • the strip 4 is partially wound around deflection rollers 8, 9, 10, 11 and 12 and then enters a housing 13 disposed on a rigid frame 15, located in the lower part 14 of the reel 1.
  • this housing 13 are arranged variable speed drive means 16 of the strip 4, these variable speed drive means 16 being described below and more simply called drive means 16.
  • the strip 4 goes towards a regulating device 17 making it possible to give the strip 4 a constant tension at the outlet of the reel 1.
  • the strip 4 After passing through the regulating device 17, the strip 4 is guided towards a sizing device on one or both sides of the strip 4 depending on whether it is intended either to be applied directly to the mandrel of the forming machine or to constitute the external face of the tubular profile, or to form an intermediate layer of the latter.
  • the regulating device 17 consists of a metal frame 18 mounted vertically on the rigid frame 15 and comprising in its upper part 19 a series of rollers 20, 21 and 22 arranged perpendicular to the direction of advance of the strip 4.
  • the device regulator 17 also includes a diabolo 23 formed of two rollers 24, 25 parallel and connected to each other at their end by means of a console 26 or the like. This diabolo 23 can be subjected to an upward and / or downward movement, this displacement being effected along guide rails arranged vertically and placed on either side of said diabolo 23.
  • the strip 4 passes alternately around one of the rollers 20, 21 and 22 then around one of the rollers 24, 25 of the diabolo 23.
  • the strip 4 is partially wound around a fixed deflection roller 27, placed halfway up the frame metal 18 at the outlet of the regulating device 17.
  • the tension of the strip 4 at the outlet of the reel 1 is only a function of the number of strands 28 formed by the strip 4 in the regulating device 17 and of the weight of the dolly 23 resting at the bottom of the grooves 29 of these strands 28.
  • the regulating device 17 forms a tape storage magazine 4, which makes it possible to replace an empty reel with a full reel without stopping the production of wound tube.
  • This lifting device 30 is formed by a triangular arm 31 comprising at its end 32 a gripping device 33 of the coils 3 or 6 provided with self-locking pliers 34.
  • the drive means 16 of the strip 4 disposed in the housing 13, have the function of giving said strip 4 a variable advance speed controlled by the advance speed of the latter at the outlet of the device. regulation 17. Since each of the bands 4 used to produce a tubular profile has a different feed speed, each of these bands corresponds to the drive means 16. However, all of these are solicited by a single variable speed motor 78.
  • the housing 13 comprises two flanks 35, 36 arranged parallel and on either side of the vertical median plane 37 of the strip 4, between these flanks 35, 36 are inserted the drive means 16.
  • the latter consist of a driving roller 38 mounted in free rotation on an axis 39 perpendicular to the vertical median plane 37 and the ends 40 of which are secured to the sides 35, 36.
  • the strip 4 is partially wound around this driving roller 38 before going towards the regulating device 17.
  • the driving roller 38 in rotation by means of motor elements 41, it is possible to animate the strip 4 with a movement of advance.
  • the latter is introduced between said driving roller 38 and a pressing roller 42, disposed parallel to and above the latter.
  • the pressure roller 42 is applied, with a certain effort, to the drive roller 38.
  • the pressure roller 42 is secured, at its ends 43, to levers 44 arranged perpendicularly to the axis of the drive roller 38.
  • These levers 44 are pivotally mounted, at their lower end 45, on an axis 46 disposed perpendicular to the vertical median plane 37 of the strip 4.
  • This axis 46 is fixed at its ends to the sides 35, 36 of the housing 13. So that the pressure roller 42 applies, with a certain pressure, on the driving roller 38, the levers 44 have in their upper part 47 elastic means 48 exerting a pull down on these said levers 44.
  • these elastic means 48 are consist of tension springs 49 connected at their upper end to the levers 44 and at their lower end to the sides 35, 36 or to the rigid frame 15. Thanks to this arrangement, the pressure roller 42 makes it possible to increase the adhesion nce of the strip 4 on the driving roller 38.
  • the latter may include a coating with a high coefficient of friction allowing this adhesion to be improved.
  • the axis 46 to which the levers 44 are fixed, also serves as a support for a deflector 50.
  • a deflector 50 For this purpose, on the axis 46 are mounted two rings 51 immobilized in rotation by means of fixing means, such as screws , to these rings 51 being welded the deflector 50.
  • the latter is of semi-cylindrical shape whose axis is approximately coincident with the axis of rotation of the driving roller 38.
  • This deflector 50 makes it possible, on the one hand, to avoid projections oil or grease on strip 4 and, on the other hand, cause the latter to be partially wound around the driving roller 38.
  • the driving elements 41 making it possible to drive the driving roller 38 in rotation comprise a shaft 52 disposed parallel to the driving roller 38, in the rear part of the housing 13 and comprising its ends 53 engaged in rolling bearings 54 integral with the sides 35, 36
  • On this shaft 52 is mounted, in a fixed manner, a crown 55 driven in rotation by means of a transmission 56 and a motor shaft 57.
  • the latter arranged perpendicular to the direction of advance of the bands 4 to 1.
  • 'rear of the housings 13 is mounted on the rigid chassis 15 by means of plummer block housings 58.
  • the motor shaft 57 is coupled at one end to a variable speed motor 78 and can stress the drive means 16 of several bands 4.
  • the transmission 56 consists of a pinion 59 mounted on the drive shaft 57 and of a chain or belt 60 partially winding around the crown 55 and the pinion 59.
  • the driving elements 41 of the driving means 16 comprise two transmission systems 61, 62 with different ratios, connecting the shaft 52 to the driving roller 38.
  • Each of these transmission systems 61, 62 consists of a pinion 63 mounted on the shaft 52, a pinion 64 mounted in free rotation on the axis 39, support of the driving roller 37 , and a chain or belt 65 engaging the toothing of the pinion 63 and the pinion 64 respectively.
  • These transmission systems 61, 62 are arranged symmetrically with respect to the vertical median plane 37 of the band 4, the pinions 63 being located approximately at the ends 53 of the shaft 52 and the pinions 64 being made integral with the driving roller 38 by means of hubs 66 arranged at the ends 67 of the latter.
  • One of these transmission systems 61, 62 corresponds to a rapid speed of advance of the band 4 giving the latter a speed of advance greater, by about fifteen percent, than the speed of the band 4 at the output. of the regulating device 17.
  • this fast speed transmission system must be actuated when the dolly 23 is in a high position so as to reconstitute the stock of tape 4 in the regulating device 17.
  • the other system transmission 62 corresponds to a slow speed of advance of the band 4 making it possible to animate the latter by a speed lower, by about fifteen percent, than its speed of advance at the output of the regulating device 17. This system transmission 62 must therefore be actuated when the dolly 23 is in a low position.
  • the pinions 63 are integral with clutches 68 engaged on the shaft 52 and immobilized in rotation by means of torque arms 69 fixed to a crosspiece 70 connecting the two sides 35 , 36 of the housing 13. So as not to hinder the rotation of the crown 55, this crosspiece 70 is located in the upper part of the sides 35, 36 and at the rear end of the latter.
  • the shaft 52 drives the pinion 63 corresponding to the slow speed transmission system 62 or to the fast speed transmission system 61.
  • the regulating device 17 comprises positioning detectors 71, 72 arranged in the same vertical plane and cooperating with the diabolo 23. Therefore, when the diabolo 23 acts on the lower positioning detector 71, the latter controls the operation of the slow speed transmission system 62 while causing the disengagement of the pinion 63 corresponding to the high speed transmission system 61. On the other hand, when the diabolo 23 acts on the upper positioning detector 72, the disengagement of the pinion 63, corresponding to the slow speed transmission system 62 is actuated and the fast speed transmission system 61 is engaged.
  • the distance between the two positioning detectors 71, 72 defines the range of variation of the speeds of the drive means 16.
  • the diabolo 23 cooperates with a third positioning detector 73 disposed under the lower positioning detector 71 and in the same vertical plane as the latter.
  • This positioning detector 73 has the function of controlling the stopping of the advance of the strip 4 by means of a braking device 74. This arrangement makes it possible to prevent the diabolo 23 from coming to the end of the low stroke and the strip 4 continues to be driven.
  • the braking device 74 is composed of a pinion 75 around which the chain or belt 65 of the fast-speed transmission system 61 is partially wound.
  • the pinion 75 is integral with a brake 76 mounted on an axis 77 arranged in parallel and between the shaft 52 and the driving roller 38.
  • the drive means 16 do not have a sufficient range of variation in the speed of rotation of the driving roller 38.
  • the drive shaft 57 is formed by several shaft sections (80, 81, 82), (see FIG. 4), driving each other by means of gears or systems of any transmission (83, 84) making it possible to give each of these shaft sections (80, 81, 82) a different speed of rotation.
  • This variation in the speed of rotation of the shaft sections must be gradual so that the shaft section corresponding to the drive means 16 of the bands 4 coming to be placed near the mandrel of the forming machine has the speed the slower while the shaft section corresponding to the drive means 16 of the bands 4 forming the outer layers of the tubular section has the fastest speed of rotation.
