Definitions

  • the present invention relates to machines intended for abrasion machining and in particular for sanding wood.
  • the device according to the invention overcomes these drawbacks. It allows an increased speed of passage and allows synchronization with the machines used upstream of the continuous chain and in the case especially wood with saws, planers and four-sided. It also allows the prolonged storage of parts intended to receive paints, varnishes or other decorations.
  • the device according to the present invention allowing the evacuation of the particles removed from the surface of the material, is notably remarkable in that the abrasive pads in reciprocating motion are slightly lifted at each end of their travel.
  • the device according to the invention comprises various means for slightly lifting the pad at the end of the stroke in order to allow the evacuation of the particles accumulated during each movement.
  • the graph in Plate 1, Figures 1 and 2, explains the movement.
  • Figure 1 shows the oscillation movement, that is to say longitudinal only (represented by the forces F and Fl) and the application force F 'always constant for a given job.
  • FIG. 2 represents the movement resulting from the combination of the oscillating movements and the movement in height caused by the made of the relative inertia of the raw assembly by the self-weight of the mechanism and the applied force F '; a and c are the liftings, b is the rectilinear movement.
  • the invention provides for the injection of air or any other fluid between the pad and the surface to be machined, this fluid being brought into this space by channels through the support and the pad.
  • the location of the connection duct in the support and in the shoe is designated by the reference 23 in Figures 5, 6, 9 and 10.
  • the first device represented by FIGS. 5, 6, 7 and 8 comprises a housing 1 provided internally with rails 2 on which the rollers 3 of the carriage 4 will roll.
  • the latter is made integral with the housing by a jack 5 which makes it possible to raise the pads or apply them with a given pressure on the material to be machined.
  • the carriage 4 includes the vibrating system. This is composed, for each skid, of links 6 articulated on the axis 7 provided with Timken bearings with deformable spacers.
  • the flanges support everything and serve as a grease guard.
  • the pads are fixed to the other end of the rods using silentblocks 8 held by the axis 9.
  • the opposite reciprocating movement of the two pads is obtained by the eccentrics 10 linked by rods to the silentblocks 11 (axis 12).
  • the movement resulting from the pads develops according to the graph in Figures 1 and 2.
  • the pads are mounted on the carriage 13 by means of the silentblocs 14 and the axis 15.
  • This carriage is guided by the rollers 16 which roll in the recesses 17 of the frame 18.
  • These recesses have a shape intended to reproduce the movement defined by the graph of Figures 1 and 2.
  • the force F ', Figures 1 and 2 is provided as in the previous system by a jack, rails and rollers similar to those described in Figures 5, 6, 7, 8.
  • the vibrating assembly is formed of silentblocs 19 (partial section CD) and of the crankshaft with eccentrics 20 provided with silentbloc 21.
  • the resulting movement is obtained by a carriage identical to the system described in the first mode ( Figures 5 to 8) and ensuring the application of the force F ', Figures 1 and 2, or by engine weight and hand pressure if the system is used as a hand machine instead of an automatic machine.
  • the jack is replaced, in FIGS. 5 to 10, by an electromagnet of desired power.
  • the movement in lifting height at the end of the travel is obtained directly by an electromagnet replacing the jack 5, and controlled by a static contactor controlled by the rotation of the eccentric.
  • conduit 23 Figures 5, 6, 9, 10, connected pu fluid generator. It will open between the abrasive and the material to be machined through holes or grooves dictated by the shape of the profile in order to ensure the removal of the particles removed in the best way.
  • the device which is the object of the improvement can advantageously be applied to the sanding of wood for moldings, cabinet-making, buildings, parquet floors, etc., and in particular in continuous production chains. It can also be used to modify the surface condition of plastics and metals.
