Description

    PRIORITY CLAIM
  • This application claims priority from Italian Patent Application No. 102017000056951 filed on May 25, 2017 .
  • The present invention relates to a machine for edgebanding panels of wood or the like.
  • In particular, the present invention relates to a machine for edgebanding panels of wood or the like of the type comprising an edgebanding assembly; and a feeding device defining a support surface for the panels.
  • The panels are fed in succession by the feeding device through the edgebanding assembly to allow the edgebanding assembly to apply a finishing edge along at least part of a lateral profile of each panel.
  • The edgebanding assembly comprises a glueing device for applying glue onto the lateral profile of the panel and/or onto the finishing edge, and a pressing device for stabilizing the finishing edge on the panel.
  • The glueing device comprises a tank for containing the glue, and a glueing roller, which is fitted so as to rotate around a rotation axis, extends inside the tank to take the glue, and protrudes out of the tank to apply the glue onto the lateral profile of the panel and/or onto the finishing edge.
  • The known machines for edgebanding panels of wood or the like of the type described above have some drawbacks mainly arising from the fact that the replacement of the glue with a glue of a different colour or having different chemical-physical characteristics requires emptying, cleaning, and refilling the tank, and therefore entails relatively high maintenance costs and relatively long setup times.
  • The object of the present invention is to provide a machine for edgebanding panels of wood or the like, which is free from the drawbacks described above and simple and inexpensive to implement.
  • According to the present invention, a machine for edgebanding panels of wood 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 illustrate a non-limiting embodiment thereof, in which:
    • Figure 1 is a schematic plan view, with parts removed for clarity, of a preferred embodiment of the machine for machining components of wood or the like of the present invention;
    • Figure 2 is a schematic plan view, with parts removed for clarity, of a first variant of the machine in Figure 1; and
    • Figure 3 is a schematic plan view, with parts removed for clarity, of a second variant of the machine in Figure 1.
  • With reference to Figure 1, number 1 indicates, as a whole, a machine for edgebanding panels 2 of wood or the like.
  • Each panel 2 has two main faces 3 parallel and opposite to each other, and is bounded by a lateral profile 4, which extends between the two faces 3, and comprises, in this case, two minor lateral faces 5 parallel to each other and perpendicular to a horizontal direction 6 and two minor lateral faces 7 parallel to each other and perpendicular to a horizontal direction 8, which is transverse to direction 6.
  • The machine 1 comprises a feeding device 9 of a known type, which defines a substantially horizontal support surface P for the panels 2, and is configured for feeding the panels 2 successively in direction 6.
  • The machine 1 also comprises an edgebanding assembly 10 configured to apply a finishing edge 11 onto the lateral profile 4 of the panel 2.
  • The assembly 10 comprises a glueing roller 12, which is fitted so as to rotate around a vertical rotation axis 13 and is adapted to apply glue onto the lateral profile 4, in particular onto one of the faces 7; and a train of pressing rollers 14, which are fitted so as to rotate around respective rotation axes 15, which are parallel to each other and to the axis 13, and are adapted to stabilize the edge 11 on the panel 2.
  • The roller 12 is fed around axis 13 through a glueing station 16, at which the roller 12 transfers the glue onto the panel 2, and a feeding station 17, at which the glue is fed onto the roller 12 by a feeding unit 18.
  • In this case, the unit 18 comprises a tank 19 for containing the glue and a spray dispenser 20 (for example a spray gun) for transferring the glue from the tank 19 to the roller 12.
  • In other words, the roller 12 is completely fitted on the outside of the tank 19 so as to allow the feeding unit 18 to be rapidly replaced, while keeping the roller 12 fixed.
  • The roller 12 further cooperates with a cleaning device 21, preferably, but not necessarily, a heated doctor blade, which is fitted between station 16 and station 17 downstream of station 16 in a moving direction 22 of the roller 12 around the axis 13.
  • The device 21 removes the glue remaining on the roller 12 downstream of station 16 in direction 22 so as to feed the clean roller 12 through station 17.
  • The variant shown in Figure 2 differs from what shown in Figure 1 solely in that the feeding unit 18 therein is removed and replaced with a feeding unit 23 comprising a tank 24 for containing the glue and a transfer roller 25, which is fitted so as to rotate around a rotation axis 26 parallel to axis 13, extends inside the tank 24 to take the glue, and protrudes out of the tank 24 to apply the glue onto the roller 12.
  • The variant shown in Figure 3 differs from what shown in Figure 1 solely in that the edgebanding assembly 10 therein comprises a plurality of feeding units 18, which are distributed around axis 13 and are associated with respective types of glue, which are different from each other in colour and/or chemical-physical characteristics.
  • The units 18 are connected to an electronic control unit 27 configured for selectively controlling the operation of the units 18, for example by moving each unit 18 between an operating position, in which the unit 18 feeds the glue to the roller 12, and a rest position.
  • According to a variant, not shown, the feeding unit 18 is removed and replaced with at least one feeding unit comprising a tank for containing the glue and a spreading dispenser for transferring the glue from the tank to the roller 12.
  • According to a further variant, not shown, the glueing roller 12 is arranged so as to apply the glue onto the finishing edge 11.
