Definitions

  • the invention relates to an automatic cutting device for circular tubes of small, medium and large thickness obtained by gluing several strips of fibrous, cellulosic, metallic, plastic materials and, in general, any material in strips and produced at using a spiraling machine, a roll forming machine or an extruder.
  • a cutting device for tubular elements of cardboard and similar materials installed on a machine allowing the production of tubular packaging made up of strips glued on one another according to a determined pitch, these strips being made of fibrous, cellulosic, metallic, plastic and other materials.
  • This cutting device allowing a cut on the fly, comprises a carriage sliding along a rail held by supports. On this carriage is mounted an electric motor, the shaft of which is provided with a saw blade provided with teeth. This cooperates with a cutting counter-roller secured to the carriage. The latter is integral with a translation device ensuring the advance of the carriage. A certain space is provided between the saw blade and the counter roller to allow the passage of the tubular element. During cutting, the saw blade is brought forward, subjected to continuous rotation by the electric motor, in the direction of the counter-roller.
  • machines making it possible to make packages as defined above.
  • These machines include two drums movable in rotation and connected to each other by a belt describing a helical movement causing, on the one hand, a helical winding of the different strips of paper, metal and others previously provided with a layer of glue and, d on the other hand, the continuous advance of the tubular element on a spindle.
  • a shaft requesting a multiple cutting device subjected to a displacement in the axis of advance of the tubular element whose variable speeds of advance and cuts are synchronized with the speed of advance of the tubular element.
  • This device has a number of saw blades corresponding to the number of cuts you want to make.
  • These cutting elements are subjected to a triple displacement in space, namely a rotation about its axis, a pendulum movement to cut the tubular element and a longitudinal displacement according to the advance of the tubular element.
  • the present invention aims to remedy these drawbacks.
  • the invention as characterized in the claims, solves the problem of creating an automatic cutting device for circular tubes of small, medium and large thickness, obtained by bonding of several strips of fibrous, cellulosic, metallic, plastic materials and, in general, any material in strips and produced using a spinner, a profiling machine or an extruder, comprising a fixed mandrel on which the circular tube from the spiring machine, profiling machine or extruder rotates freely and driven without constraint on either side of the cutting line by counter-rollers subjected to a rotational movement synchronized with the speed of rotation of the circular tube, this fixed mandrel cooperating for cutting with at least one cutting assembly provided with a knife machined in a very sharp double bevel immobile in rotation at the time of cutting by blocking means but conferring on said knife cutting a fragmented rotation between two consecutive cuts.
  • each cutting assembly comprises means ensuring a blocking of the cutting knife during cutting but giving said cutting knife a fragmented rotation taking place between two consecutive cuts.
  • the cutting device 1 comprises a mandrel 2 made of a material resistant to wear but whose coefficient of friction is low. According to the invention, this mandrel 2 is fixed from the rotation point of view. On the outer periphery 3 of this mandrel 2 freely rotates a circular tube 4 coming from a spiraling machine, a profiling machine or an extruder. This circular tube 4 is obtained by gluing several strips of fibrous, cellulosic, metallic, plastic materials, and, in general, any material in strips. Because the mandrel 2 has a very low coefficient of friction, the circular tube 4 easily rotates on said mandrel 2.
  • These two counter rollers 8, 9 comprising a metal core provided with an adherent coating, are subjected to a rotational movement whose speed is synchronized with the speed of rotation of the circular tube 4.
  • the two counter rollers 8, 9 are integral in rotation with a shaft 10, 11 disposed at one end 12, 13 of two pairs of levers 14, 15.
  • On the shaft 10, 11 is mounted, integral in rotation, the driven element 16, 17 of a transmission 18, 19.
  • the latter is driven by a motor element 20, 21.
  • These two motor elements 20, 21 are integral in rotation d an intermediate shaft 22 disposed at the other end 23, 24 of the pairs of levers 14, 15.
  • This intermediate shaft 22 also serves as an axis of rotation 25 for the pairs of levers 14, 15.
  • On this intermediate shaft 22 is fixed, integral in rotation, a driven element 26 of a central transmission 27 whose motor element 28 is integral in rotation with the shaft 29 of a gearmotor-variator 30.
  • each lever cylinder 31, 32 To apply the two counter rollers 8, 9 against the outer periphery 5 of the circular tube 4 or vice versa to break the contact between the two counter rollers 8, 9 and the outer periphery 5 of the circular tube 4, there is provided for each lever cylinder 31, 32.
  • the pistons 33, 34 of these cylinders 31, 32 are connected by a hinge pin 35, 36 to a yoke 37, 38 secured to each of the levers 14, 15 while the end 39, 40 of cylinders 31, 32 is connected by a hinge pin 41, 42 to the frame (not shown) of the cutting device.
  • a cutting assembly which consists essentially of a knife machined in a very sharp double bevel 43.
  • This knife 43 can pivot around an axis 44 held by a pair of levers 45.
  • These levers 45 can pivot around an axis 46 located at one of the ends 47 of the levers 45, this axis 46 being held by bearings 48 integral with the frame.
  • the other end 49 of the levers 45 is connected by an axis 50 to the piston 51 of a cylinder 52.
  • This cylinder 52 connected by an axis 53 to the frame, causes the levers 45 to tilt around the axis 46.
  • the speed of the stroke of the piston 51 of the jack 52 is adjustable as a function of the speed of rotation of the circular tube 2.
  • the cutting knife 43 is, in the cutting phase, locked in rotation.
  • the cutting knife 43 comprises a ratchet wheel 54 integral in rotation with said cutting knife 43.
  • the teeth 55 of this ratchet wheel 54 cooperate with a pawl 56 secured to a piston 57 of a jack 58 made integral by a hinge pin 59 to the piston 51 of the jack 52.
  • the pawl 56 rotates the ratchet wheel 54 and, consequently, blocks the cutting knife in rotation 43.
  • actuation the jack 58 actuation the jack 58.
  • the pawl 56 causes a partial rotation of the cutting knife 43. As a result, the latter is subjected to a fragmented rotation.
  • lubrication means 60 are also provided, consisting of a lubrication nozzle 61 disposed at the end of a lubrication circuit 62.
