Description

  • The present invention relates to a sanding machine for sanding wood panels or the like.
  • In particular, the present invention relates to a sanding machine, as e.g. known from document EP-A1-2 253 428 , comprising a conveyor belt, which has an upper transport line defining a substantially horizontal support plane for at least one panel, and is adapted to move the panel forward beneath a sanding device comprising, in turn, an upper tensioning drum, a lower drive drum, and an abrasive belt which is wound in a ring shape around the tensioning drum and the drive drum so as to sand an upper face of the panel.
  • The drive drum generally comprises a support shaft, which has a given first longitudinal axis, and is provided with two eccentric ends coaxial to each other and to a second longitudinal axis parallel to the first axis; and a cylindrical sleeve, which extends around the support shaft coaxially to the first axis, and is rotationally coupled to the support shaft so as to rotate, with respect to the support shaft, around said first axis.
  • The drive drum is moved around the second axis between a lowered operating position, in which the abrasive belt is arranged in contact with the upper face of the panel, and a raised rest position, in which the abrasive belt disengages the panel, by means of an actuating cylinder which is connected to a support frame of the drive drum, and has an output rod connected to a crank splined on one of the eccentric ends of the supporting shaft.
  • Since the lowered operating position of the drive drum is fixed, the known sanding machines of the above-described type have few drawbacks mainly deriving from the fact that the abrasive belt removes a greater quantity of material than that expected when the thickness of the panel is greater than a nominal value, it removes a lesser quantity of material than that expected when the thickness of the panel is less than the nominal value, and does not remove any material when the thickness of the panel is less than a threshold value.
  • The object of the present invention is to provide a sanding machine for sanding wood panels or the like which is free from the above-described drawbacks and which is simple and cost-effective to be implemented.
  • According to the present invention, a sanding machine for sanding wood panels or the like is provided as claimed in the appended claims.
  • The present invention will now be described with reference to the accompanying drawings, which show an embodiment thereof by way of non-limiting example, in which:
    • figure 1 is a diagrammatic perspective view, with parts removed for clarity, of a preferred embodiment of the sanding machine according to the present invention;
    • figure 2 is a diagrammatic side view, with parts in section and parts removed for clarity, of the sanding machine in figure 1; and
    • figure 3 is a diagrammatic side view, with parts removed for clarity, of a detail of the sanding machine in figures 1 and 2.
  • With reference to figure 1, numeral 1 indicates, as a whole, a sanding machine for sanding wood panels 2 or the like having a substantially parallelepiped shape.
  • Sanding machine 1 comprises a supporting frame 3, and an infeed device 4 comprising, in turn, a conveyor belt 5, which is wound in a ring shape around a pair of motorized pulleys 6 mounted so as to rotate around respective longitudinal axes 7 which are parallel to each other and to a horizontal direction 8, has an upper transport line defining a horizontal support plane P for at least one panel 2, and is adapted to move panel 2 forward in a direction 9 which is horizontal and transversal to direction 8.
  • Sanding machine 1 further comprises a sanding unit 10 comprising, in turn, an abrasive belt 11 wound in a ring shape around a lower drive drum 12 and an upper tensioning drum 13 of the known type, which is mounted so as to rotate around a longitudinal axis 14 thereof which is parallel to axes 7, and is movable, with respect to frame 3, in a direction 15 which is vertical and orthogonal to directions 8 and 9 between a lowered rest position and a raised operating position.
  • As shown in figure 2, drum 12 comprises a support shaft 16, which has a longitudinal axis 17 parallel to axes 7 and 14, and is provided with two eccentric ends 18, which are coaxial to each other and to a longitudinal axis 19 parallel to axis 17, and are rotationally coupled to frame 3 so as to allow shaft 16 to rotate, with respect to frame 3, around axis 19. Shaft 16 further comprises a crank 20, which is splined on one of the ends 18, and extends radially outwards from said end 18.
  • Drum 12 further comprises a cylindrical sleeve 21, which extends around shaft 16 coaxially to axis 17, and is rotationally coupled to shaft 16 so as to rotate, with respect to shaft 16 and under the thrust of an actuating device 22 of the known type, around said axis 17.
  • Drum 12 is movable around axis 19 between a lowered operating position, in which belt 11 is arranged in contact with an upper face 23 of panel 2, and a raised rest position, in which belt 11 disengages said face 23.
  • Drum 12 is moved, and normally kept, in its lowered operating position by gravity under the thrust of its own weight, and is moved from its lowered operating position to its raised rest position by an actuating device 24 (figure 3) comprising a rocker arm 25 which is rotationally coupled to the crank 20 so as to rotate, with respect to shaft 16, around axis 19.
  • Device 24 further comprises a first actuating cylinder 26, which is connected to frame 3, and has an output rod 27, which is connected to a first arm of the rocker arm 25, and is movable between a backward position (figure 3) and an extracted position (not shown); and a second actuating cylinder 28, which is fixed to a second arm of the rocker arm 25, and has an output rod 29, which is provided with a free end adapted to be arranged in contact with crank 20, and is movable to and from a backward position (figure 3).
  • The operation of drum 12 and device 24 will now be described with reference to figure 3 and starting when rod 27 is arranged in its forward extracted position, rod 29 is arranged in its backward position, and drum 12 is arranged in its raised rest position.
  • Following the movement of rod 27 from its forward extracted position to its backward position, rocker arm 25 rotates around axis 19 in a clockwise direction, crank 20 and drum 12 rotate around axis 19 also in a clockwise direction by gravity under the thrust of the weight of drum 12, and drum 12 is arranged in its lowered operating position in contact with the upper face 23 of panel 2 independently of the effective thickness of said panel 2.
  • When drum 12 is arranged in contact with panel 2, rod 29 is moved into a forward extracted position so as to exert on drum 12 a torque around axis 19, in any case lower than the torque with opposite sign which is exerted on drum 12 by the weight of said drum 12.
  • Consequently, as a function of the profile of face 23, drum 12 oscillates around axis 19 in a clockwise direction under the thrust of its own weight when the thickness of panel 2 decreases, and in an anticlockwise direction under the thrust of panel 2 and cylinder 28 when the thickness of panel 2 increases.
  • At the end of the machining operation, rod 29 is again moved to its backward position, and rod 27 is again moved to its forward extracted position so as to rotate the rocker arm 25 in an anticlockwise direction and to allow rod 29 to move crank 20 in an anticlockwise direction around axis 19 and drum 12 to its raised rest position.
  • With regard to the above description, it should be noted that:
    • cylinder 28 defines a shock absorber device adapted to allow drum 12 to oscillate around axis 19 as a function of the profile of upper face 23 of panel 2 and, therefore, abrasive belt 11 to remove a constant quantity of material from the whole face 23 itself; and
    • the thrust exerted by rod 29 on crank 20 is selectively controlled by means of a control device (not shown) associated with cylinder 28.
  • Finally, device 24 comprises a limit member 30, which is mounted to the rocker arm 25 on the opposite side to cylinder 28 with respect to crank 20, is movable with respect to the rocker arm 25 to and from cylinder 28 so as to selectively control the oscillation of drum 12 around axis 19, and furthermore is movable to a limit position (not shown), in which member 30 locks crank 20 against the rod 29 of cylinder 28 so as to prevent it from oscillating around axis 19.
  • According to a variation (not shown), cylinder 28 is eliminated and replaced with a shock absorber device comprising a pushing member cooperating with crank 20 and a spring interposed between the rocker arm 25 and said pushing member.
