Definitions

  • the present invention refers to a sharpening unit with disc wear recovery for a stick or log cutting machine.
  • cutting to size of these final rolls is performed by cutting machines which receive the individual log, for example, and cut it in succession into a number of shorter rolls, each with the required dimensions.
  • These cutting machines use rotating blades, in the form of cutting discs, which cut the log or stick as it is gradually fed step by step, reducing it into a number of pieces of the required size.
  • disc blades feature a sharpened part or cutting edge which, as it is used, wears out or is lost and must be dressed in order to operate as required.
  • the main object of the present invention is to produce a sharpening unit that solves the above problems.
  • a further object of the present invention is to produce a unit for sharpening the discs of a cutting machine that eliminates the problems with connection of the electrical and electronic parts by means of rotating elements.
  • a further object of the present invention is to produce a unit for sharpening the discs of a cutting machine in which the moving masses are reduced to a minimum, eliminating all related problems.
  • a sharpening unit 11 is shown with wear recovery of a cutting disc 12 for the head 15 of a stick or log cutting machine, schematised in 13, on a feed surface 14.
  • the cutting unit consisting of two cutting heads 15 arranged diametrically opposite each other, is fitted on a general cross member 16 which can be moved up and/or down with respect to the feed surface 14 by means of a control unit, not shown, and is rotated by means of a central shaft 17.
  • a sleeve 18 is fixed to the cross member 16 and is positioned coaxial externally to the central shaft 17, which passes inside it.
  • the sleeve 18 supports, revolving via bearings 19, a rotating arm 20 which extends from both sides of the central shaft 17 and is fitted with a pair of cutting heads 15 of the cutting machine.
  • Each cutting head 15 has its own structure and is fitted with the above-mentioned cutting disc 12.
  • the cutting disc 12 is rotated by a kinematic chain (not specifically shown) fitted at the end with a timing pulley 21 moved by a timing belt 22, due also to the presence of relay pulleys 23.
  • a profiled box 24 bearing the moving part of the cutting disc 12 is rotated by a further pulley 25, controlled by a belt 26, with relay pulleys 23, and coaxial to the timing pulley 21.
  • Each cutting disc 12 rotates around a rotation axis 27 which can be moved according to the movements of the rotating arm 20 and profiled box 24.
  • the sharpening unit 11 is positioned in a cutting machine of the type described above.
  • the sharpening unit 11 comprises, revolving axially around the rotation axis 27 of each cutting disc 12, a lever 28 supported at one end by bearings 29.
  • the lever 28 houses a linear guide 30 bearing a trolley 31 on which two grinding wheels 33 are fitted by means of a supporting plate 32.
  • the two grinding wheels 33 each have X axis slanting in the opposite direction to the other grinding wheel axis thus collaborating from opposite sides with the cutting edge 35 of the cutting disc 12.
  • the trolley 31 bears half of an articulated joint such as a hinged joint or a ball joint 36, the second half of which is positioned on a further lever 37 controlled by a secondary rotation shaft 38 positioned coaxially inside the central shaft 17, which is the fulcrum of the lever 37.
  • the lever 37 is also supported by bearings 39 on the outer surface of the central shaft 17 which bears the rotating arm 20 with the cutting discs 12.
  • the secondary rotation shaft 38 is thus independent of the central or main rotation shaft 17.
  • the main rotation shaft 17 of the rotating arm 20 and the secondary rotation shaft 38 of the further lever 37 are connected to an angle timing device 40.
  • Said angle timing device 40 takes its movement from a main motor 42 and, via a transmission with differential inside the timing device 40, permits transmission in a ratio of 1/1 between the two outlet shafts 17 and 38.
  • This angle timing device 40 has the job of angle timing the two shafts 17 and 38 also with the shafts moving.
  • synchronised movement elements can be provided such as electronic or electromechanical means for co-ordinating rotation of the central shaft and secondary shaft.
  • a retiming motor 41 of the angle timing device 40 varies the angle between the main tool holder arm 20 and the wear control lever 37 on the cutting discs 12.
  • Variation of this angle involves sliding of the grinding wheel trolley 31 on the linear guide 30 positioned on the lever 28 hinged coaxially to each cutting disc 12. Sliding of the trolley 31 causes the grinding wheels 33 fitted on the same to move nearer or farther away from the centre of the disc.
  • a sharpening unit therefore permits sharpening of the cutting discs while they are moving, without any problem, directly preparing for said operation as the cutting disc diameter is gradually reduced by wear.
