Definitions

  • the present invention relates to a trimming assembly for the finishing of wood panels or the like.
  • Each panel has two larger lateral faces, which are parallel to one another, is delimited by a lateral profile, which is substantially transverse to the larger lateral faces, and has a finishing edge, which is glued along at least part of the lateral profile.
  • the trimming assembly normally comprises a support frame; a horizontal slide, which is coupled to the support frame in a sliding manner by means of the interposition of a first shock absorber device, so as to carry out horizontal movements relative to the support frame; and a pair of vertical slides facing one another, each coupled to the horizontal slide in a sliding manner by means of the interposition of a second shock absorber device, so as to carry out vertical movements relative to the horizontal slide.
  • the trimming assembly comprises, furthermore, a pair of trimming tools, which are engaged in the relative vertical slides in a rotary and axially fixed manner and, moreover, are coupled in a sliding and angularly fixed manner to a first splined transmission shaft, which is mounted so as to rotate around a first rotation axis.
  • the two trimming assemblies are associated with respective vertical copy attachments, which, in use, are arranged in contact with the larger lateral faces of the panel, and with a horizontal copy attachment, which, in use, is arranged in contact with the finishing edge.
  • the trimming assembly also has a second transmission shaft, which extends through the support frame, is configured to be axially locked on a tool carrier spindle of a work centre, and is caused to rotate by the tool carrier spindle around a second rotation axis.
  • the second transmission shaft is coupled to the first transmission shaft in an angularly fixed manner by means of the interposition of a coupling joint, which is configured so as to allow the two trimming tools to correctly follow both the outline of the larger lateral faces and the outline of the lateral profile.
  • the two trimming tools are arranged on opposite sides of the panel, the two vertical copy attachments are moved so as to come into contact with the larger lateral faces, and the horizontal copy attachment is caused to come into contact with the finishing edge.
  • the vertical copy attachments and the horizontal copy attachment allow the trimming tools to correctly follow both the outline of the larger lateral faces and the outline of the finishing edge and, therefore, to correctly carry out the trimming of two longitudinal corners of the finishing edge that project from the larger lateral faces themselves.
  • the coupling joint is subject to wear and can jeopardize the correct operation of the trimming assembly.
  • number 1 indicates, as a whole, a trimming assembly for the finishing of substantially flat wood panels 2 or the like.
  • each panel 2 substantially has the shape of a parallelepiped, is delimited by two larger lateral faces 3, which are parallel to one another, and, furthermore, is delimited by a lateral profile 4, which is substantially transverse to the faces 3 themselves.
  • the panel 2 is provided with a finishing edge 5, which is glued along at least part of the profile 4, and has, in an initial configuration of its, two longitudinal corners 6, which are opposite to one another and project from the faces 3 perpendicularly to the faces 3 themselves.
  • the trimming assembly 1 comprises a support frame 7, which has a box-like shape, and is engaged in a rotary manner by a coupling shaft 8 having a longitudinal axis 9 that is parallel to a substantially vertical direction 10.
  • the shaft 8 has, furthermore, an upper appendage 11 substantially having the shape of a truncated cone, which projects upwards from the frame 7, and allows the trimming assembly 1 to be coupled to a tool carrier spindle (not shown) of a work centre (not shown).
  • the frame 7 and, therefore, the trimming assembly 1 can be oriented around the axis 9 in a known manner as a function of the profile of the panel 2 being processed.
  • the frame 7 supports a horizontal slide 12, which extends under the frame 7, and is coupled to the frame 7 in a sliding manner, so as carry out, relative to the frame 7 itself and in a way that will be better described below, straight movements in a horizontal direction 13 that is transverse to the direction 10.
  • the slide 12 is substantially L-shaped with a concavity facing downwards, and comprises a horizontal plate 14, which is coupled to the frame 7, and a vertical upright 15, which projects downwards from the plate 14 parallel to the direction 10.
  • the slide 12 is coupled to the frame 7 in a sliding manner by means of the interposition of a shock absorber device (not shown) comprising a pair of coupling pins, which are fixed to the frame 7 on opposite sides of the plate 14 in the direction 13, extend parallel to the direction 13, and are engaged in a sliding manner inside respective cavities obtained in the plate 14 itself.
  • a shock absorber device (not shown) comprising a pair of coupling pins, which are fixed to the frame 7 on opposite sides of the plate 14 in the direction 13, extend parallel to the direction 13, and are engaged in a sliding manner inside respective cavities obtained in the plate 14 itself.
  • each cavity houses, on the inside, a spring, which is fitted on the relative coupling pin, and is interposed between the frame 7 and the plate 14.
  • the upright 15 is engaged by two vertical slides 16, 17 in a sliding manner, the slide 16 being arranged above the slide 17.
  • Each slide 16, 17 is coupled to the upright 15 in a sliding manner, so as to carry out, along the upright 15 and due to the thrust of at least one relative actuator cylinder (not shown), straight movements in the direction 10.
  • Each slide 16, 17 houses, on the inside, an electric motor 18 provided with an output shaft 19, which is, in particular, coaxial to the axis 9, faces the shaft 19 of the other motor 18, and is coupled to the slide 16, 17 in a rotary manner by means of the interposition of a pair of rolling bearings 20.
  • Each motor 18 is supplied with power through an electric circuit 21 comprising a first portion 22, which is mounted on the trimming assembly 1, and a second portion (not shown), which is carried by the aforesaid tool carrier spindle (not shown) of the work centre (not shown) and is connected to the portion 22 through of a plurality of electric contacts 23.
  • the trimming assembly 1 is configured as an operating head, which is permanently mounted on the work centre (not shown) and, therefore, is provided with its own power supply circuit.
  • Each shaft 19 has, splined on it, a known trimming tool 24, which is configured to trim one of the longitudinal corners 6 of the edge 5, and is caused to rotate around the axis 9 by the relative motor 18.
  • Each trimming tool 24 cooperates with a known vertical copy attachment 25, which is mounted on the relative slide 16, 17, and is aligned with the other copy attachment 25 in the direction 10.
  • the two copy attachments 25 are arranged on opposite sides of the panel 2 in the direction 10 and in contact with the relative faces 3.
  • the thrust exerted upon the copy attachments 15 and, therefore, on the slides 16, 17 by the panel 2 is substantially equal to the thrust exerted upon the slides 16, 17 themselves by the relative actuator cylinders (not shown), so as to allow the trimming tools 24 to correctly follow the outline of the faces 3 of the panel 2 being processed.
  • the two trimming tools 24 are associated, furthermore, to a known horizontal copy attachment 26, which is fixed to the upright 15 in the direction 10, and is arranged in contact with the edge 5.
  • the thrust exerted upon the copy attachments 26 and, therefore, on the slide 12 by the panel 2 is substantially equal to the thrust exerted upon the slide 12 itself by the aforesaid springs (not shown), so as to allow the trimming tools 24 to correctly follow the outline of the profile 4 of the panel 2 being processed.
  • each trimming tool 24 is caused to rotate around the axis 9 by its own electric motor 18, the trimming assembly 1 has a relatively small number of components and, therefore, is relatively simple and low-cost.
  • the replacement of the trimming tools 24 is relatively easy and involves relatively short set-up times.
