Definitions

  • the faces of interior door and window frames are normally composed of strips of wood or a wood surrogate fitted on a frame and orthogonally joined by edgings in wood or a wood surrogate, protruding above one side in such a way as to form, as a whole, an essentially L-shaped cross-section.
  • the main purpose of this invention is to provide a method and relevant implementation device aimed at accelerating the production process of said faces in wood and/or wood surrogate with L-shaped cross section.
  • Another purpose of this invention is to in any case provide a method and relevant implementation device to obtain faces in wood and/or surrogate wood with L-shaped cross-section in an as effective and immediate as possible manner by longitudinal realization of boards with side leaves fed in succession.
  • Figure 1, 1 indicates a schematically illustrated machine as a whole for implementation of the method according to this invention, comprising a sliding surface (2) between flaps (3) for a pair of overlaid boards (4 and 5), fed in whatever known way, translated at the tail end by a pair of pushers (6), driven in whatever known way, and held in place at the top by a train of guide presser rollers (7).
  • the overlaid boards (4 and 5) are to be understood as boards in any wood or wood surrogate material, for example so-called "MDF”, acronym for “medium density fibreboard”, or triturated recycled wood fibre paste, mixed with resins, pressed and dried.
  • MDF wood or wood surrogate material
  • the device (1) comprises the following additional elements and operating devices, to be understood adequately supported and anchored, as well as motor-driven in whatever known way suited to the purpose:
  • a turnover station (16) [see Figure 2] where the upper board (5) with relevant side leaves (10A and 11A) is turned over 180° by appropriate means, not illustrated, suited to the purpose, and with such orientation is positioned in sequence with the lower board (4) with relevant side leaves (10B and 11B) on the conveying line (2); a cutting station (17) [see Figure 3] where the boards (4 and 5) are cut by means of a circular saw (15) with horizontal rotation axis thus forming the strips 4A and 4B as well as 5A and 5B; a separating station (18) [see Figure 4] where the strips 4A and 4B as well as 5A and 5B are separated by means of progressive separating wedges (19) introduced between the strips 4A and 4B as well as 5A and 5B; a shaping station (20) [see Figure 5] where the strips 4A and 4B as well as 5A and 5B are shaped by means of mills (21) which model the faces (22).
  • a coating station (23) [see Figure 6] where the faces (22) are covered by means of a single sheet of coating material (24), for example, plastic or paper of known type, if necessary wound on a reel not illustrated, supplied in known manner with a film of glue and cut crosswise to the desired size, for example, by a laser cutting device, schematically illustrated and indicated with 27; within this framework, the sheet of coating material (24) is made to adhere to the faces (22) by means of pressers (25) and simultaneously separated by a cutter (26) which cuts through the middle and separates the two strips respectively dedicated to each of the two faces (22) which are thus perfectly trimmed and finished (see Figure 7).
  • a single sheet of coating material for example, plastic or paper of known type, if necessary wound on a reel not illustrated, supplied in known manner with a film of glue and cut crosswise to the desired size, for example, by a laser cutting device, schematically illustrated and indicated with 27; within this framework, the sheet of coating material (24) is made to adhere to the faces (22) by means of pressers (25) and
  • the overlaid boards (4 and 5) can be fed on the sliding surface (2) in whatever way suited to the purpose and there pushed at the tail by the pushers (6), for such a purpose driven under the sliding surface (2), for example by means of assembling a multiplicity of pushers suitably interspaced on motor-driven chains.
  • the vertical mills (8) smooth the relevant twin frames, where the gluing devices (9) immediately spread a layer of appropriate glue to which the edgings (10 and 11) are made to adhere by means of the pressers (12) as well as trimmed at the edges by the fixed horizontal mills (13).
  • the first pair of mobile horizontal mills (13A) for a stretch leads the forward movement of the side edgings (10 and 11) smoothing the respective heads with respect to the overlaid boards (4 and 5) and the second pair of mobile horizontal mills (13B) for a stretch tracks the forward movement of the side edgings (10 and 11) to smooth the respective tails with respect to the overlaid boards (4 and 5).
  • the upper board (5) with relevant side leaves 10A and 11A is turned over 180° and with such orientation is positioned in sequence with the lower board (4) with relevant side leaves 10B and 11B on the conveying line (2) [see Figure 2].
  • the boards (4 and 5) following each other consecutively are cut by means of a circular saw (15) with horizontal rotation axis, thus forming the strips 4A and 4B as well as 5A and 5B [see Figure 3].
  • the strips 4A and 4B as well as 5A and 5B are reciprocally separated by means of progressively separating wedges (19), which are introduced between them as they move forward (see Figure 4).
  • the strips 4A and 4B as well as 5A and 5B are shaped into the respective faces (22) by the mills (21) [see Figure 5].
  • the sheet of coating material (23) is fed and deposited in known manner on the thus shaped faces, there made to adhere by means of the pressers (25) and simultaneously separated through the middle into respective strips on the faces (22) [see Figure 6], which are thus perfectly trimmed and finished [see Figure 7].
  • the two overlaid boards can also be obtained from a single board split longitudinally, for example by vertical axis saws, structured and dimensioned such as not to be restricted to only cutting of the side edgings along the surface of the two overlaid boards, as in the implementation example described, but rather to separate a single board of adequate thickness for such a purpose into two overlaid boards.
  • Board feeding upstream of the relevant turnover station does not necessarily have to be accomplished with the device illustrated in Figures 1 A and 1B, but rather the downstream procedure phases and the relevant implementation devices may find constructive and effective application whatever the form of feeding of a succession of boards with side leaves.
  • the cutting, separating and milling operations of the strips can usefully be inverted in the relevant sequence, in the sense that modelling of the faces can be carried out on the still joined board to then reciprocally be detached and separated subsequent to modelling in order to be coated.
  • the separating action of the strips or faces can alternatively be carried out, rather than by wedges as described in the example, also by tracks that engage the lower profiles of strips or faces and reciprocally deviate from their path, or roller units, or conveyor belts, or anything else suited to the purpose.
  • the coating material can be also be cut into two strips before application.
  • the implementation devices of all the procedure phases can be of any type and kind suited to the purpose.
