Definitions

  • the invention relates to a machine for processing panels made of wood, plastic material, glass or the like.
  • the invention especially finds advantageous application in the processing of panels made of plastic material, to which explicit reference will be made in the description below without because of this losing in generality.
  • a machine which comprises an elongated base, which extends in a first direction and defines a support surface for at least one panel; a locking device to lock the panel on the support surface; and an overhead crane, which extends above the base in a second direction that is transverse to the first direction, is movable along the base in the first direction and is provided with at least one operating head to process the panel.
  • the operating head is movable along the overhead crane in the second direction and is provided with an operating unit, which is movable in a third direction that is orthogonal to the aforesaid first and second directions and to the support surface.
  • the operating unit supports a cutting blade, which is movable in the third direction in order to engage/disengage the panel.
  • the object of the invention is to provide a machine for processing panels made of wood, plastic material, glass or the like, which is not affected by the aforementioned drawbacks and can be manufactured in a simple and economic fashion.
  • the invention further relates to a method for processing panels made of wood, plastic material, glass or the like.
  • number 1 indicates, as a whole, a machine for processing panels 2 ( figure 2 ) with a substantially rectangular shape, in this case panels 2 made of a plastic material.
  • the machine 1 comprises an elongated base 3, which extends in a horizontal direction 4 and is delimited by a substantially horizontal upper face 5 provided with a plurality of openings 6, which can be connected to a known pneumatic suction device, which is not shown herein.
  • the panels 2 are locked on the face 5, in this case, with the interposition of at least one intermediate sheet (not shown), which is commonly referred to as "support panel” and defines a support surface for the panels 2.
  • the panels 2 are locked on the face 5 with the interposition of a relatively stiff first sheet, which is in contact with the face 5, and of a relatively soft second sheet, which defines the support surface for the panels 2.
  • the base 3 is engaged in a sliding manner by an overhead crane 7, which extends above the base 3 in a horizontal direction 8 transverse to the direction 4, is movable along the base 3 in the direction 4 and supports at least one operating head 9 to process the panels 2.
  • the head 9 is coupled to the overhead crane 7 in a sliding manner so as to move, relative to the overhead crane 7, in the direction 8 and supports an operating unit 10, which is coupled to the head 9 so as to move, relative to the head 9, in a vertical direction 11, which is orthogonal to the directions 4 and 8 and to the aforesaid support surface (which is not shown herein).
  • the unit 10 is provided with a cutting blade 12, which is moved by the overhead crane 7 in the direction 4, by the head 9 in the direction 8 and by the unit 10 in the direction 11.
  • the movement of the unit 10 in the direction 11 allows the blade 12 to move between a lowered operating position ( figure 2 ), in which the blade 12 engages the panel 2, and a raised rest position (not shown), in which the blade 12 disengages the panel 2.
  • the unit 10 is further provided with a heating device 13 to heat the blade 12 and/or a portion 14 of panel 2 suited to be processed by the blade 12.
  • the device 13 comprises, in this case, a vortex tube 15 comprising, in turn, an outlet duct 16, which has a longitudinal axis 17 and is provided with two free ends 18, 19 opposite one another.
  • the end 18 is axially open and the end 19 is closed by a distribution valve 20, which is designed to selectively control the air flow fed through the end 19.
  • the tube 15 further comprises an inlet duct 21, which has a longitudinal axis 22 transverse to the axis 17, is connected to the duct 16 and is further connected to a known compressed air feeding device, which is not shown herein.
  • the duct 21 is obtained in the area of an intermediate point of the duct 16 so that the distance between the end 18 and the duct 21 is smaller than the distance between the end 19 and the duct 21.
  • Compressed air is fed, at first, through the duct 21 and, then, in the duct 16 in a tangential manner so as to generate a compressed air flow, which flows towards the end 19 with a helical motion around and along the aforesaid axis 17, thus heating up.
  • the flow of heated compressed air is divided into two compressed air flows, one of them being discharged through the valve 20, while the other one is fed again along the duct 16 and, at the end 18, releases its kinetic energy in the form of heat and cools down.
  • the device 13 further comprises, in this case, a flexible tube 23, which is connected to the end 19 in order to receive, at the inlet, the heated compressed air fed through the valve 20 and has, in this case, an outlet 24 oriented towards the blade 12.
  • the tube 23 has two outlets 24, one of them being oriented towards the blade 12 and the other one being oriented towards the portion 14.
  • the tube 23 is eliminated and the heated compressed air discharged through the valve 20 is fed onto the blade 12 and/or onto the portion 14.
  • the blade 12 and/or the portion 14 are heated before the processing of the blade 12 and/or during the processing of the blade 12.
  • the heating device 13 is eliminated and replaced by different heating devices configured to heat the blade 12 and/or the portion 14, such as, for example, infrared light sources, ultrasound sources, magnetic field sources, microwave sources, plasma sources or laser sources.
  • the heating device 13 allows the blade 12 and/or the portion 14 to be heated so as to facilitate the cutting of the panel 2. As a consequence, the blade 12 has a relatively high cutting speed and the machine 1 has a relatively high productivity.
