Definitions

  • the present invention relates to vertical panel splitting machines, particularly for wood panels (but its application to panels of any other material, such as plastic or glass, for example, is not excluded), of the type comprising:
  • FIG. 1 is a perspective schematic view of the machine that illustrates the fixed support structure 1, defining a substantially vertical plane 2, (the plane is slightly inclined with respect to the vertical to ensure that the wood panels to be split rest on a stable base) on which a structure to act as a traverser carriage is fitted to slide horizontally, including a vertical upright 2, the ends of which are fitted to slide on the upper and lower horizontal edges of fixed structure 1 (see also figure 2 , which illustrates a side view of the machine).
  • Figure 3 of the annexed drawings shows a diagram of the detail of operating head 5 illustrated at a distance from a panel L to be split. Normally, in machines of this type, the operating head is fitted articulated around an axis parallel to the aforementioned orthogonal direction to plane 2, in such a way that the circular blade carried by it can be oriented both for performing vertical cuts and for performing horizontal cuts on the panel.
  • Figure 3 illustrates a plan view, and thus in this figure operating head 5 is oriented at 90° to the position illustrated in figure 1 , with the axis of rotation 7 of the circular blade 8 that it supports oriented in a vertical direction.
  • Operating head 5 presents a principal cover 5a that supports circular blade 8, rotating around axis 7, which serves to split panel L (that is, to cut through the entire thickness of the panel), and a further circular blade 9, that turns around an axis 10 parallel to axis 7, to cut into panel L.
  • auxiliary cover 11 first comes into contact with L panel.
  • the further advancement in direction X of operating head 5 causes auxiliary cover 11 to retract into principal cover 5a with consequent protrusion of circular blade 8 through a slit (not visible in figure 3 ) formed in front surface 11a.
  • the purpose of the present invention is to resolve the aforementioned problem.
  • the object of the invention is a vertical splitting machine having all the characteristics that were indicated at the start, and, moreover, characterised by the fact that an additional protection structure is attached to the aforementioned auxiliary cover and is also guided in such a way as to slide with respect to the principal cover and which includes a surface that covers the above aperture in the auxiliary cover, in such a way as to exclude any possibility of access to the circular blade.
  • the invention is aimed at both the vertical splitting machine as a whole, as defined in the annexed independent claims 1 or 8, and at a circular blade protection assembly as defined in the attached independent claim 6, which may be adapted on a machine of the known type described above in order to equip it with the additional characteristic defined above.
  • the invention presents the advantage of allowing vertical splitting machines for wood panels that are optimal in terms of operator safety to be created or adapted with extremely simple means, and at low cost.
  • auxiliary cover 11 is attached to additional protection structure 14 presenting an upper surface 14a that is fitted to slide over principal cover 5a of operating head 5, and a front surface 14b that, in conjunction with upper surface 14 a, completely covers aperture 12 in auxiliary cover 11, rendering circular blade 8 completely inaccessible, even in the extracted condition illustrated in figures 3 and 4 .
  • Figure 4 of the annexed drawings refers to the initial condition, in which operating head 5 is set at a distance from a wood panel to be split.
  • auxiliary cover 11 is in its extracted condition (in which it is maintained by elastic means not visible in the figure) and thus covers circular blade 8.
  • Aperture 12 in upper surface 11b of auxiliary cover 11 is instead surmounted by additional protection structure 14, which is attached in some way (with screws, for example) to auxiliary cover 11.
  • Figures 4-6 also show slit 11c in frontal surface 11a of auxiliary cover 11, through which circular blade 8 can protrude.
  • Figure 5 illustrates the condition in which, after advancement of operating head 5 in direction X, approaching panel L, front surface 11a of auxiliary cover 11 comes into contact with panel L. Further advancement of head 5 (see figure 6 ) causes both the retraction of auxiliary cover 11 from principal cover 5 (causing circular blade 8 to protrude through slit 11c) and the retraction of additional protection structure 14. In this condition, blade 8 penetrates in wood thickness and thus it is able to split the panel.
  • Figure 7 illustrates a perspective view of additional protection structure 14, with its upper surface 14a fitted to slide over the upper surface of cover 5a. Adjacent to structure 14, a further structure 15 is envisaged, separated from or integrated with structure 14 which, in a way similar to structure 14, has the function of covering aperture 13 in correspondence with cutting disk 9.
  • Figure 7 also illustrates the construction details (which are of a known type) of the articulation that allows the operating head with circular blade 8 to be oriented vertically or horizontally. These details may be executed in any known manner and, of themselves, are not part of the scope of this invention.
  • Both additional protection structure 14 and structure 15 may be made in any suitable material, such as metal sheet, or metal mesh, or synthetic material, including transparent material, or in any other form.
  • Figures 8 and 9 show an alternative embodiment in which the additional protection structure consists of two plates 16 hinged to auxiliary cover 11 in a reciprocal scissor-like arrangement with the interposition of elastic means (not shown) that tend to pull plates 16 into a closed condition in which they cover aperture 12.
  • Plates 16 also each present cam surfaces 16a that, during the translation of auxiliary cover 11 inside principal cover 5a, work with the rotation shaft of circular blade 8 in such a way that the plates are turned by said shaft, against the action of the aforementioned elastic means, so as to clear aperture 12 and allow the shaft of circular blade 8 to be received inside it.
  • plates 16 described above may be replaced by a single plate fitted on auxiliary cover 11 in a way similar to that described above, able to cover the whole of aperture 12 on its own.
  • the additional protection structure includes an extendible panel 17 fitted in correspondence with aperture 12.
  • Panel 17 is attached from one side of auxiliary cover 11 to the opposite side on principal cover 5a.
  • panel 17 assumes an extended configuration in which it covers aperture 12 when auxiliary cover 11 is in extracted condition, while when auxiliary cover 11 is in retracted condition it presents a packed configuration in which a portion of aperture 12, recessed in cover 5a, is cleared, to enable the shaft of circular blade 8 to be received inside this aperture.
  • panel 17 may be formed by a set of telescopically interconnected metal strips, or by a cap presenting sections that are reciprocally connected in a pivoting way.
  • protection structures represented in figures 8 to 11 in correspondence with aperture 12 of circular blade 8, may also be fitted in correspondence with aperture 13 of the cutting disk.
