Definitions

  • the present invention relates to a machine to drill into panels made of wood or the like.
  • the present invention relates to a machine to drill into panels made of wood or the like of the type comprising an elongated base extending in a first, substantially horizontal direction; a roller support device, which is mounted on the base so as to define a support surface for the panels; a feeding device to feed the panels along a feeding path extending between a panel loading station to load the panels onto the roller support device and a panel unloading station to unload the panels from the roller support device; and a drilling station obtained along the panel feeding path.
  • the feeding device generally comprises at least one clamp member, which is mounted and configured so as to grab and hold the panels in the area of a side of theirs parallel to the first direction and is movable along the base in order to feed the panels on the roller support device and through the drilling station.
  • the drilling station is normally provided with at least one drilling head comprising a plurality of lower vertical drill bits, which are mounted under the support surface, a plurality of upper vertical drill bits, which are mounted above the support surface, and a plurality of horizontal drill bits.
  • the horizontal and vertical drill bits generally are movable in a second, substantially horizontal direction, which is transverse to the first direction, and in a third, substantially vertical direction, which is orthogonal to the panel support surface.
  • holes are vertically drilled into each panel by moving the vertical drill bits in the third direction and holes are horizontally drilled into each panel by moving the panel in the first direction.
  • Machines to drill into panels made of wood or the like of the type described above are affected by some drawbacks, which are mainly due to the fact that the configuration of the drilling head and the combination of the movements of the panel in the first direction and of the horizontal and vertical drill bits in the aforesaid second and third directions allow users to drill into one single panel at a time, hence ensuring a relatively small productivity.
  • the object of the present invention is to provide a machine to drill into panels made of wood or the like, which is designed to eliminate the aforementioned drawbacks in a straightforward, relatively low-cost manner.
  • the present invention further relates to a method to drill into panels made of wood or the like.
  • number 1 indicates, as a whole, a machine to drill into flat panels 2 substantially having the shape of a parallelepiped.
  • the machine 1 comprises an elongated base 3, which extends in a horizontal direction 4 and supports two roller devices 5a, 5b arranged on opposite sides of two drilling stations 6, 7 in the direction 4 itself.
  • Each device 5a, 5b has a plurality of rollers 8, which are mounted so as to rotate around respective rotation axes 9 parallel to one another and to a horizontal direction 10 transverse to the direction 4 and define a support surface P for the panels 2.
  • the stations 6, 7 are mounted one after the other in the direction 4 and are provided with a horizontal drilling head 11 and with a vertical drilling head 12, respectively.
  • the head 11 comprises a first horizontal slide 13, which is coupled to the base 3 in a sliding manner so as to make, relative to the base 3, straight movements in the direction 4; a vertical slide 14, which is coupled to the slide 13 in a sliding manner so as to make, relative to the slide 13, straight movements in a vertical direction 15, which is orthogonal to the directions 4 and 10 and to the plane P; and a second horizontal slide 16, which is coupled to the slide 14 in a sliding manner so as to make, relative to the slide 14, straight movements in the direction 10.
  • the slide 16 supports a plurality of electrospindles 17 next to one another, which extend in the direction 4 and each carry, fitted into them, a respective pair of horizontal drill bits 18 opposite one another.
  • the bits 18 cooperate with two pressing devices 19a, 19b, which extend in the direction 10 and are arranged on opposite sides of the head 11 in the direction 4.
  • Each pressing device 19a, 19b is movable in the direction 15, independently of the other pressing device 19a, 19b, between a locking position to lock the panels 2 on the support surface P and a release position.
  • the head 12 comprises two upper drilling units 20, which are mounted above the surface P, and two lower drilling units 21, which are mounted under the surface P.
  • Each unit 20, 21 is mounted on the base 3 so as to move in the directions 10 and 15 and comprises a plurality of electrospindles 22, which are arranged parallel to the direction 15 and each carry, fitted into them, a respective vertical drill bit 23.
  • the machine 1 is further provided with a feeding device 24 to feed the panels 2 in the direction 4 along a feeding path S extending through the stations 6 and 7.
  • the device 24 comprises a longitudinal guide member 25, which extends along the base 3 in the direction 4, is mounted beside the roller devices 5a, 5b and supports a pair of clamp members 26.
  • Each member 26 is coupled to the longitudinal member 25 in a sliding manner so as to make straight movements in the direction 4 and comprises two substantially flat jaws 27, which are perpendicular to the direction 15.
  • the jaws 27 project from the longitudinal member 25 in the direction 10, are oriented and configured so as to grab and hold a side of the panels 2 parallel to the direction 4 and are movable relative to one another in the direction 15 between a clamping position and a release position to clamp and release the panels 2.
  • a first panel 2 is loaded, either manually or by means of a known feeding device, onto the roller device 5a upstream of the head 11 in the direction 4 and is locked on the surface P by means of the pressing device 19a.
  • the head 11 drills into a front side face 2a of the panel 2 by moving the slide 13 and, hence, the bits 18 in the direction 4.
  • the pressing device 19a is lifted and the panel 2 is grabbed by the clamp members 26 of the feeding device 24, is moved onto the roller device 5b downstream of the head 11 in the direction 4 and is locked on the surface P by means of the pressing device 19b.
  • the head 11 drills into a rear side face 2b of the panel 2 by moving the slide 13 and, hence, the bits 18 in the direction 4.
  • a second panel 2 is loaded, either manually or by means of a known feeding device, onto the roller device 5a upstream of the head 11 in the direction 4 and is locked on the surface P by means of the pressing device 19a.
  • the head 11 drills into the face 2a of the second panel 2 and, simultaneously, the head 12 drills into the upper and lower faces 2c of the first panel 2.
  • the head 11 Since the drilling of the faces 2a and 2b of each panel 2 is carried out by locking the panel 2 on the surface P and by moving the bits 18 in the direction 4, the head 11 has a relatively high precision.
  • the locking of the panels 2 on the surface P and the movement of the bits 18 in the direction 4 allow users to simultaneously carry out the drilling of the face 2a of a panel 2 through the head 11 and the drilling of the faces 2c of another panel 2 through the head 12, ensuring the machine 1 a relatively high productivity.
