Definitions

  • the present invention relates to a tobacco shredding machine.
  • the subject of the invention is a machine of the type comprising a main supporting structure, fixed, in which is arranged a tobacco feeder device with conveyor belts one above the other and converging, capable of pushing a mass or block of tobacco towards an outlet opening or aperture in said structure and a rotating cutting device fitted so as to pivot about a substantially horizontal axis in front of said outlet aperture, in an auxiliary support structure connected movably to the main structure; the rotating cutting device having a plurality of knives which extend horizontally, spaced at equal angular intervals about the axis of rotation, and which are capable successively of cutting across and penetrating into the mass or block of tobacco which in operation is made to advance by said feeder device at the above-mentioned outlet aperture.
  • the purpose of the present invention is to produce a machine of this type, designed to allow the operations of cleaning and of removal and replacement of the knives of the rotating cutting device to be executed easily and safely.
  • auxiliary support structure is fitted so as to be capable of translational movement with respect to the main structure in a transverse horizontal direction, parallel to the axis of rotation of the cutting device, between an operating or working position in which the rotating cutting device extends in front of the outlet aperture of the tobacco feeder device, and a non-operating position in which the rotating cutting device extends transversely beside said outlet aperture, which is uncovered and directly accessible.
  • the number 1 is used to indicate as a whole a tobacco shredding machine according to the present invention.
  • the machine 1 comprises a fixed main support structure 2, resting on the ground by means of a plurality of feet 3.
  • a tobacco feeder device is arranged in the main support structure 2.
  • This device basically comprises two conveyor belts 5 and 6, respectively upper and lower, converging towards the front end of the machine, and capable of pushing a mass or block of tobacco T towards an outlet opening or aperture 7 (figures 2 and 3).
  • the shredding machine 1 also comprises an auxiliary support structure, indicated as a whole by the number 9, fitted so as to be capable of translational movement relative to the front face of the main structure 2, in a transverse horizontal direction, along a cylindrical guide bar 10 (see figure 2 in particular) fixed in the upper part of the main structure.
  • an auxiliary support structure indicated as a whole by the number 9, fitted so as to be capable of translational movement relative to the front face of the main structure 2, in a transverse horizontal direction, along a cylindrical guide bar 10 (see figure 2 in particular) fixed in the upper part of the main structure.
  • a rotating cutting device shown as a whole by the number 11, capable of revolving about a horizontal axis indicated by A-A in figure 1.
  • This cutting device in a manner known in itself, comprises a rotating drum or barrel 12, having an axial appendage 13 to which is keyed a pulley 14 coupled by means of a belt 15 to a pulley 16 keyed to the shaft of a motor (for example) an electric motor 17, carried at the top by the auxiliary support structure (figures 1 and 3).
  • the rotating cutting device 11 carries eight knives or cutting blades 18 (figure 2) running horizontally, spaced at equal angular intervals about the axis of rotation A-A.
  • the knives 18 of the cutting device 11 are capable successively of cutting across and penetrating into the mass or block of tobacco T which is made to advance by the feeder device 4 at the outlet aperture 7.
  • the auxiliary support structure 9 is capable of translational movement horizontally along the cylindrical guide 10, as a result of the operation of a drive device 19, which may be of the electromechanical or hydraulic type.
  • the auxiliary support structure 9 when 'the auxiliary support structure 9 is in the working position shown in figures 1 and 2, part of it projects into the main support structure 2, in particular at its rotating cutting device 11. For this reason, the auxiliary structure 9 is not immediately capable of translational movement relative to the main support structure 2.
  • the latter is appropriately swivellable about the axis of the cylindrical guide 10, between the operating position shown by continuous lines in figure 2 and an angularly rotated position, also shown, but in broken lines, in said figure 2.
  • This swivelling of the auxiliary structure 9 can be controlled by means of a thrust crosspiece 20 (figures 2 and 3) the ends of which are connected to the rods 21a (figure 2) of two hydraulic actuators 21 (figure 3). Further hydraulic actuators 22 for raising/lowering (figures 2 and 3) are also appropriately involved in swivelling the auxiliary support structure 9, being coupled to the rods 21a of the actuators 21 by means of suitable mechanisms, one of which is shown by broken lines in figure 2, where it is indicated by the number 23.
  • the auxiliary supporting structure 9 is capable of translational movement horizontally, in a transverse direction, that is parallel to the axis of the rotating cutting device 11, by means of the drive device 19, until it reaches the position shown in figure 3 in which the cutting device 11 is located beside the outlet aperture 7, and the latter is uncovered and directly accessible to an operator.
  • a grinding device 24 is installed, comprising a revolving annular grinding wheel 25.
  • This grinding device 24 may be swivelled between a non-operating position, shown by broken lines in figure 2, and an operating position, shown by solid lines, in which it is coupled to a traversing device, capable of imparting horizontal translational movement to it along two guides 26.
  • This translational movement is produced by means of a motor 27 (figures 1 and 3) attached to the upper part of the auxiliary structure 9, the shaft of which is coupled by means of a belt transmission 29 to a worm screw 28.
  • the latter is engaged in a nut component of a carriage 30 capable of translational motion along the guides 26, and to which is coupled the grinding device when it is arranged in the operating condition shown by continuous lines in figure 2.
  • Operation of the motor 27 therefore causes translational movement of the grinding device 24 along the horizontal working travel defined by the guides 26 in such a way that the grinding wheel 25 is applied successively to the sharpened portion or cutting-edge of each of the knives 18 of the rotating cutting device.
  • the auxiliary support structure 9 also appropriately carries a dressing device, indicated as a whole by the number 31, of a type known in itself, capable of dressing the working surface of the grindstone 25 of the sharpening device 24.
  • the rotating cutting device comprises a blade movement mechanism capable of providing outward movement or advance, or inward movement or withdrawal of the knife.
  • this mechanism comprises a shaft 32, revolving in one direction to cause outward movement and in the other to cause withdrawal of the knife.
  • This shaft can be coupled to a first drive device 33 (figure 4) by means of a front clutch 34 of the friction type.
  • the drive device 33 is arranged to cause rotation of the shaft 32 at relatively low speed so as to cause, in normal operation of the shredding machine, a slow progressive outward movement or advance of the associated knife 18, in order to compensate for blade wear.
  • a second drive unit 40 is attached to the auxiliary support structure 9 and is shown, viewed from above partly in section and at a larger scale, in figure 5.
  • This second drive unit can be coupled selectively to the blade movement mechanism for a knife 18 of the rotating cutting device 11 when the latter is in a predetermined angular position, to cause an inward or outward movement of this knife at a relatively higher speed compared with that produced by means of the motor 33, for example for executing an operation of replacing this knife with a new one and repositioning the new knife.
  • the drive unit 40 basically comprises a motor 41, with an output shaft or spindle 42 which can be coupled to the end of the shaft 32 opposite the associated motor 33, by a clutch of the end face type indicated as a whole by the number 43 in figure 5.
  • the front clutch 43 can be closed and therefore the shaft 42 of the motor 41 coupled to the shaft 32 by means of an actuator 44 comprising a control device 45 capable of translational movement which, when this actuator is operated, can cause translational movement of the rod 35 at the same time, and therefore open the friction clutch 34 and couple the motor 41 to the shaft 32.
  • the rotating cutting device 11 can be positioned successively in the n angular positions in which in each case one of its knives 18 is located in a reference position in which it can easily be removed and replaced, and in which the associated rod 35 and the corresponding shaft 32 line up with the component of the actuator 44 capable of translational movement and with the shaft of the motor 41.
  • the positioning of the rotating cutting device 11 in said n angular positions may be achieved using a cam unit coaxial and integral with said cutting device, provided with n peripheral slots into which a retaining and stabilising pawl or claw may be fitted, and which may be controlled for example by means of a manually operated hydraulic device.
  • the motor 41 causes the new knife to move until its sharp portion or cutting-edge reaches the nominal operating position close to the periphery of the rotating cutting device.
  • the sensor device 50 shown in figures 6 and 7 may appropriately be used.
  • This device in the embodiment illustrated comprises an arm 51 connected to the auxiliary support structure 9 so that it can be swivelled between a working position, shown by continuous lines in figures 6 and 7, and a parked position, shown by broken lines in figure 7.
  • the arm 51 carries a sensor 52, constituted for example by a precision microswitch.
  • the sensor 52 When the arm 51 is located in the working position shown by solid lines in the drawings, the sensor 52 extends over the outward travel of the knife 18 being positioned. When, under the action of the motor 41, the knife 18 being positioned touches the sensor 52 with its cutting edge, the sensor supplies a control apparatus (not shown) with an electrical signal, capable of causing deactivation of the motor 41.
  • the device 50 may be repositioned manually in the parked condition, and the rotating cutting device 11 can be made to rotate, so as to bring a new knife into the reference position in which the sensor 50 is located.
