Definitions

  • the present invention generally relates to paper converting machines, and more precisely it relates to a transversal cutting machine of the type having a rocking saw for logs of paper and the like for the production of rolls of toilet paper, all purpose and industrial rolls, stacks of napkins and the like.
  • the invention relates to a method for driving a saw and causing it to follow a complex orbit.
  • the invention relates to a drive apparatus of a saw that carries out such method.
  • Transversal cutting machines are known for making rolls or stacks of paper, for example rolls of toilet paper, general purpose towels, napkins and the like, which are supplied with logs of paper wound upstream.
  • one or more logs are placed on a bench for their stepped conveying. Then, the downstream ends of the logs pass in turn through a cutting off section and are held by a clamp device so that a rocking saw is driven through the paper for cutting off in succession the rolls or stacks. More precisely, before of each lowering motion of the saw onto the logs, the latter are pushed forward axially for a distance equal to the length of each final roll or stack. The logs are held only at the moment of the cut by means of a clamping device which allows their sliding in the stepped conveying as well.
  • Means are provided for synchronising the stepped movement of the log and the moment in which the saw is raised between two consecutive cuts.
  • most of machines are equipped with means for pushing the logs and means for rocking the saw support with independent motors, synchronised by programmable means.
  • the existing machines have means for driving the saw that can be improved both inertially, and on the effectiveness of the cut and of the cutting time.
  • additional complex means are provided, further to the components of the drive apparatus of the orbit.
  • transversal cutting machine according to the present invention as defined in claim 1 comprising:
  • the rocking frame comprises:
  • the first rocking arm is made of two parts and means are provided for adjusting its length, whereby the orbit of the saw can be adjusted for recovering the wear of the saw.
  • the length of the first rocking arm is adjustable for example by means of an electromechanical jack that adjusts the relative position of its parts.
  • crank preferably, is made of two arms bent with respect to each other and integral to each other by means of a coupling that allows the adjustment of the angle thereof. In this way the adjustment of the angle changes the distance between the axes of the crank thus changing the cutting parameters.
  • both the lengths of at least one of the two arms and the point of pivot of the first rocking arm at the drive shaft can be changed.
  • the invention is also defined by a method according to claim 6.
  • a transversal cutting machine comprises a base 1, capable of slidingly supporting a log of paper 2, for example toilet paper to cut off into rolls by means of a rocking saw 3, supported and driven by a drive apparatus 4 fixed to a frame 5.
  • a base 1 capable of slidingly supporting a log of paper 2, for example toilet paper to cut off into rolls by means of a rocking saw 3, supported and driven by a drive apparatus 4 fixed to a frame 5.
  • Saw 3 is shown in the position of top dead center of its orbit and, with dotted line, in the position of bottom dead center in which the saw has been completely driven into log 2. During the cut log 2 is held by a clamping device 6.
  • the drive apparatus 4 for driving saw 3 comprises means for adjusting the orbit versus the wear of the saw after a sharpening and according to the different cutting conditions to which the machine must be adapted.
  • the drive apparatus 4 comprises:
  • the first rocking arm 14 is made of two parts 14a and 14b, which can slide with respect to each other operated by a electromechanical jack 18. In this way, the change of length can be carried out automatically after each sharpening step of saw 3 for compensating its reduction of diameter by adjusting the trajectory of the sharpened edge for continuing the cutting off of the logs into rolls.
  • the first rocking arm 14, moreover, have portion 14a which comprises a plurality of linking housings 19 to the eccentric point 10a of drive shaft 10.
  • portion 14a which comprises a plurality of linking housings 19 to the eccentric point 10a of drive shaft 10.
  • crank mechanism 15 are variable, similarly to the change of length of first rocking arm 14, in order to adjust the orbit and then the cutting parameters.
  • Circular saw 3 of the cutting off machine therefore, follows an orbit which is the composition of two plane motions, the former being given by the first rocking arm 14 to the first point 12a of support 12 and the latter being given by crank mechanism 15 to second point 12b of support 12.
  • the former motion can be changed with continuity without stopping the machine for adjusting the trajectory of the sharpened edge of the saw after each sharpening thus allowing the continuation of the cut.
  • Both motions moreover, can be changed stopping the machine for adjusting in a discrete way the orbit of saw 3 and the approaching speed between saw and log, as well as for adjusting the exit speed and the angle of the orbit of the saw throughout the log versus the different types and size of the material to cut.
