Definitions

  • the present invention relates to a method and a machine for the production of panels made of wood or the like, as per the preamble of claims 1 and 10.
  • a prior art machine comprises an elongated base extending in a first given direction; a plurality of cross members mounted on the base parallel to a second direction crosswise to the first direction and mobile along the base in said first direction; a plurality of supporting blocks mounted on the cross members to define a supporting plane for at least one panel; and at least one working head for detaching a plurality of components from said panel.
  • Each supporting block comprises a sliding member that is mobile along the relative cross member in the second direction, and a supporting plate mounted on the output shaft of an actuating cylinder housed inside the sliding member and suitable to move the supporting plate between a lowered position, in which the supporting plate is coplanar to the supporting plane, and a raised position, in which the supporting plate projects above said supporting plane.
  • each component is detached from the panel, and is then raised above the supporting plane by means of the relative supporting plates so as to undergo further finishing processes, such as drilling and/or milling and/or edge-trimming.
  • Document DE 29616208 U1 discloses a method and a machine as per the preamble of claims 1 and 10.
  • the present invention also relates to a processing machine for panels made of wood or the like.
  • a processing machine for panels 2 made of wood or the like comprising an elongated base 3 extending in a horizontal direction 4, which is substantially U-shaped, and has two longitudinal guiding members 5 parallel to said direction 4.
  • the machine 1 also comprises a bridge crane 6, in turn comprising a vertical upright member 7, which is coupled to the base 3 in a conventional manner so as to perform, along said base 3 and driven by a conventional drive device that is not illustrated, rectilinear movements in the direction 4, and which supports a cross member 8 attached to a free end thereof and extending above the base 3 in a direction 9 horizontal and crosswise to the direction 4, and is limited laterally in said direction 4 by two faces 10, 11 arranged opposite one another.
  • a bridge crane 6 in turn comprising a vertical upright member 7, which is coupled to the base 3 in a conventional manner so as to perform, along said base 3 and driven by a conventional drive device that is not illustrated, rectilinear movements in the direction 4, and which supports a cross member 8 attached to a free end thereof and extending above the base 3 in a direction 9 horizontal and crosswise to the direction 4, and is limited laterally in said direction 4 by two faces 10, 11 arranged opposite one another.
  • the face 10 supports a conventional edge-trimming unit 12 connected in a conventional manner to the cross member 8 so as to move in the direction 9 and in a direction 13 that is vertical and orthogonal to the directions 4 and 9; and the face 11 supports a conventional working head 14, which is connected in a conventional manner to the cross member 8 so as to perform rectilinear movements along said cross member 8 in the direction 9, and comprises at least one tool-carrying spindle mounted in a conventional manner on the head 14 so as to move in the direction 13.
  • the machine 1 is also provided with a plurality of cross elements 15, which are referred to in the following description as "working planes", extending between the longitudinal members 5 and in the direction 9, and slidingly coupled to said longitudinal members 5 so as to perform, with respect to the base 3, rectilinear movements in the direction 4.
  • the working planes 15 support a plurality of supporting blocks 16, each of which is coupled in a conventional manner to the relative working plane 15 so as to perform rectilinear movements along the relative working plane 15 in the direction 9, and is upperly limited by a substantially flat and horizontal face 17 that defines, with the upper faces 17 of the other blocks 16, a substantially horizontal supporting plane P1 and is selectively connectable to a conventional pneumatic suction device that is not illustrated.
  • Each block 16 supports a lifting device 18 comprising an actuating cylinder 19 fixed to the block 16 parallel to the direction 13, and a pair of supporting rollers 20 idly mounted on the free end of an output shaft 21 of the cylinder 19 so as to rotate about an axis 22 of rotation parallel to the direction 9.
  • the rollers 20 are moved by the cylinder 19 between a lowered resting position ( figure 2 ) in which the rollers 20 are coplanar to or lower than the plane P1, and a raised working position ( figure 3 ), in which the rollers 20 define a supporting plane P2 parallel to and above said plane P1.
  • the machine 1 also comprises a feed unit 23 suitable to feed the panels 2 above the blocks 16 and comprising, in turn, a base 24, which is aligned with the base 3 in the direction 4, and supports a roller supporting device 25 and a grip and transfer unit 26.
  • the device 25 comprises a plurality of supporting bars 27 parallel to one another, which extend in the direction 4, and support relative pluralities of idle supporting rollers 28; and the unit 26 comprises a supporting bar 29, which extends in the direction 9, is mobile, with respect to the base 24, in the direction 4, and supports a plurality of gripping members 30, which are distributed along the bar 29 in the direction 9, are shaped so as to grip the panels 2 in correspondence with a rear edge thereof parallel to the direction 9, and are mobile in said direction 9 synchronously with one another during the processing of the panel 2 and independently of one another during a tooling step of the machine 1.
  • both the bars 27 of the device 25, and the bar 29 of the unit 26 are mobile, with respect to the base 24, in the direction 13 between a raised position, in which the rollers 28 and the plane P2 are substantially coplanar, and a lowered position, in which the rollers 28 and the plane P1 are substantially coplanar.
  • rollers 20 and 28 are eliminated and replaced, for instance, with ball bearings.
  • the rollers 20, the rollers 28, and the members 30 are moved to their lowered positions to release the panel 2 onto the blocks 16, and the blocks 16 are connected to said pneumatic suction device (not illustrated) to lock the panel 2 on the plane P1.
  • the working head 14 then detaches a first component 31 from the panel 2 combining the movements of the bridge crane 6 in the direction 4 with the movements of the working head 14 in the direction 9; the component 31 is locked on the plane P1; the rollers 20 not engaged by the component 31, the rollers 28, and the members 30 are then moved back into their raised positions to lift the panel 2 to the plane P2; and the work cycle described above is repeated to detach a first set of components 31 from the panel 2, said set of components 31 being aligned with one another in the direction 4, arranged at a fixed distance from one another, and then undergoing further finishing processes, e.g. edge-trimming performed by the edge-trimming unit 12 and/or milling and/or drilling performed by the working head 14.
  • edge-trimming performed by the edge-trimming unit 12 and/or milling and/or drilling performed by the working head 14.
  • the panel 2 is moved in the directions 4 and/or 9 so that the work cycle described above can be repeated and a second set of components 31 can be detached and finished.
  • the bridge crane 6 is fixed in the direction 4, the edge-trimming unit 12 and the working head 14 are fixed in the direction 9, and the components 31 are detached from the panel 2 and undergo further processing by combining the movements of the working planes 15 and of the gripping members 30 in the direction 4 with the movements of the supporting blocks 16 and of the gripping members 30 in the direction 9.
  • the alternative embodiment illustrated in figure 4 only differs from that illustrated in the previous figures in that the roller supporting device 25 has been eliminated, the panels 2 are picked up from a stack 33 of panels 2, and as each panel 2 comes to the top of the stack 33 it is first moved on the stack 33 and along the plane P2 to disengage said stack 33 and then lowered from the plane P2 to the plane P1 in order to cut the components 31.
  • the panels 2 are fed above the blocks 16 in the direction 9.
  • the pattern of cutting the components 31 from the panel 2 can clearly differ from that described and illustrated in figures 1 and 4 .
