Definitions

  • the present invention relates to a method for sanding flat wooden articles presenting recessed or relief shapings, including framed articles.
  • the invention also relates to a machine for implementing the method.
  • Articles of the aforesaid type include for example the door panels of wooden kitchen furniture units, wooden window frames, and doors themselves in particular.
  • Known sanding machines comprise:
  • the aforesaid cylindrical sanding means consist essentially of a so-called cylindrical "brush" rotatable about its own axis, in which the filiform elements of the brush extend substantially radially from a coaxial shaft and are grouped into rows normally parallel to the shaft axis and angularly equidistant. Sheets of abrasive cloth are interposed between the rows of filiform elements and have their far edge projecting beyond the free end of the filiform elements, the near edge of these sheets being fixed to the shaft of the cylindrical sanding element.
  • each sheet of abrasive cloth is cut into strips of equal width (for example 5 mm) extending outwards, this enabling the abrasive cloth, by virtue of the presence of the filiform elements, to follow the shapings of the article to be sanded.
  • FIG. 1 shows an isometric view of a generic wooden rectangular article 10 (for example a door panel of a furniture unit or an actual door).
  • the article 10 comprises two parallel lateral uprights 10.1 and 10.2 and two end crosspieces 10.3 and 10.4. It should be noted that if the article is fairly long, one or more intermediate crosspieces can also be present (not provided for simplicity in the example of Figure 1).
  • the four elements 10.1, 10.2, 10.3 and 10.4 of the article 10 essentially form a peripheral frame bounding its inner part.
  • This inner part comprises a depressed region 10.5, also in the form of a frame, adjacent to said outer frame, and a rectangular raised central region 10.6 having in this specific example an elevation equal (but could also be different) to that of the outer frame 10.1, 10.2, 10.3 and 10.4.
  • the longitudinal direction of the article 10 coincides with its direction of advancement when carried by the conveyor belt of the sanding machine, so that the crosspieces 10.3 and 10.4 extend in a direction perpendicular to the advancement direction.
  • the object of the present invention is to obviate the aforesaid drawbacks of known sanding machines, by providing a method for sanding wooden articles of the aforestated type, and a machine for their sanding by such a method.
  • stage c the following further stage is provided, consisting of:
  • the aforedescribed sanding method enables a sanding quality to be obtained which known sanding machines are totally unable to provide.
  • the method of the invention conveniently comprises a further stage consisting of:
  • the rotational speed of all the other sanding means can also be varied within determined limits, but (in contrast to said third means) maintained constant during the machining of one and the same article, such as to be able to adjust the rotational speed on the basis of the particular typology and/or type of wood of the article to be sanded.
  • the invention also relates to a sanding machine for implementing the aforedescribed method.
  • This machine has the features disclosed in claim 5.
  • the machine described above in terms of its essential characteristics can comprise fourth sanding unit comprising fourth cylindrical sanding means analogous to the third sanding means, but softer.
  • the machine can also be provided with a fifth sanding unit comprising at least one pair of fifth cylindrical sanding means, each fifth sanding means of each pair lying to one side of the transiting article so as to interfere with a longitudinal edge of this latter, the two sanding means of each pair having their axis of rotation contained in a vertical plane perpendicular to the advancement direction and symmetrically forming with the vertical an angle which can be varied between 0 and 30 degrees.
  • means in addition to providing means for varying the rotational speed of the third sanding means of the machine, means can be conveniently provided for also varying, within determined limits, the rotational speed of all the other sanding means, to enable their rotational speed to be adjusted on the basis of the particular typology and/or type of wood of the article to be sanded.
  • the machine for sanding articles of the initially stated type (for example the article 10 of Figure 1) is indicated overall by 12.
  • the machine 12 comprises a conveyor means, consisting in the specific illustrated example of a conveyor belt (but could also be another type of conveyor means, for example a roller table).
  • the two branches 14 of the conveyor means are shown only partially in Figure 2 for simplicity.
  • the articles to be sanded (not shown in Figure 2 for simplicity) are rested on the upper branch in succession and advance together with the upper branch in the direction of the arrow 16, which hence indicates the direction of advancement of the articles 10.
  • the article which advances in the direction of the arrow 16, firstly encounters that previously defined as the fifth sanding unit 18, which in this case comprises a single pair of fifth cylindrical sanding means, indicated in Figure 2 by 18.1 and 18.2 (also see Figure 3).
  • the fifth sanding unit 18 which in this case comprises a single pair of fifth cylindrical sanding means, indicated in Figure 2 by 18.1 and 18.2 (also see Figure 3).
  • these latter have their rotational axes 24.1 and 24.2 contained in a vertical plane perpendicular to the advancement direction 16 and inclinable to the vertical in this plane by an angle between 0 and 30 degrees (as indicated by the arrows 26.1 and 26.2 of Figure 3).
  • This can be useful if the longitudinal edges of the article are not vertical or are profiled, so as to obtain the best sanding result.
  • the article passes between the pair of fifth sanding means 18.1 and 18.2, each interfering with one of the two longitudinal sides of the article 10.
  • the distance between the two fifth sanding means 18.1 and 18.2 is previously adjusted such that once put into rotation, they graze the respective longitudinal edges of the article 10.
  • the machine 12 comprises reference guides 28.1 and 28.2 which enable the pair of fifth sanding means 18.1 and 18.2 to be exactly positioned on the basis of the width of the article 10.
  • the rotational speed of the fifth sanding means 18.1 and 18.2 can be varied by an inverter and relative potentiometer provided on a control panel (not shown for simplicity) of the machine 12.
  • the fifth sanding means 18.1 and 18.2 could be dispensed with (in which case the longitudinal edges of the article will be sanded manually, as happens for the transverse edges).
  • the fifth means can also be located within the machine 12 in a position different from that shown in Figure 2.
  • the article 10 encounters that previously defined as the first sanding unit 20, comprising in this specific example two first cylindrical sanding means, indicated by 20.1 and 20.2 ( Figures 2 and 4), the rotational axes of which are horizontal and inclined to the advancement direction 16 by an angle which can vary between 0 and 30 degrees.
  • the purpose of this is to obtain, on the basis of the specific article to be sanded, a softer impact against any reliefs or internal shapings of the article, which however must be of modest projection (not greater than 5 mm).
  • the sanding means 20.1 is disposed more downstream than the sanding means 20.2 so that there is no interference between the two as a result of their reciprocating movement in the horizontal direction, transverse to the advancement direction 16 (as indicated by the double arrow 22).
  • the rotational speed of the two first sanding means 20.1 and 20.2 can be varied by an inverter with a potentiometer provided on the control panel of the machine 12.
  • the reciprocating movement of the two first sanding means 20.1 and 20.2 in accordance with the double arrow 22 has an amplitude or working stroke which is determined by the position of said positioning guides 28.1 and 28.2, such that the sanding means 20.1 and 20.2 involve in practice only the crosspieces 10.3 and 10.4 and the inner flat surface 10.6 of the article 10 ( Figure 1).
  • the stroke can be further adjusted by regulators (not shown for simplicity) positioned on the fifth sanding means 18.1 and 18.2 such that the first sanding means 20.1 and 20.2 do not even interfere with the inner corners of the uprights 10.1 and 10.2.
  • the article 10 then encounters the second sanding unit 32 comprising in the specific illustrated example two second cylindrical sanding means, positioned in succession and indicated by 32.1 and 32.2 ( Figures 2, 5 and 6). They rotate about their axis in opposite directions (as indicated by the arrows 36.1 and 36.2) and are movable in the two senses in the vertical direction (as indicated by the double arrows 34.1 and 34.2). This enables the frame-shaped recessed inner surface 10.5 ( Figure 1) of the article 10 to be sanded.
  • each of the two second sanding means 32.1 and 32.2 is raised in order not to interfere with the front upper corner 10.8 of the article 10, it then being lowered to enable it to sand the recessed surface 10.5.
  • the devices for raising and lowering the second sanding means 32.1 and 32.2 comprise pneumatic cylinders controlled by solenoid valves operated electronically by a sensor positioned at the entry to the machine 12, to transmit to a central unit (not shown for simplicity, but with which the machine 12 is provided) the distance between the beginning and end of the article and the width of the crosspieces of the article 10.
  • a central unit not shown for simplicity, but with which the machine 12 is provided
  • the rotational speed of the second sanding means 32.1 and 32.2 can be varied by an inverter and potentiometer positioned on the control panel of the machine 12.
  • the article 10 then encounters said third sanding unit 38, comprising in the specific example a single third cylindrical sanding means 38 ( Figure 7) rotatable about its horizontal axis at a speed which can be varied (as in the preceding cases), this axis being perpendicular to the advancement direction 16.
  • the sanding means 38 enables sanding of those surfaces of the article 10 which have not yet been sanded, while at the same time also refining those other surfaces of the article which have substantially the same elevation (10.1, 10.2, 10.3, 10.4 and 10.6).
  • these surfaces can present small reliefs (although not shown, for simplicity, in the case of the article 10), they are prevented from being spoiled (in order not to compromise the result of the sanding) by the provision of conventional devices which enable the rotational speed of the sanding means 38 to be reduced (even by 30%) when it interferes with such reliefs.
  • a fourth sanding unit 40 comprising in this specific example a single cylindrical sanding means 40. This latter differs from the third sanding means 38 only by being “softer" (in the aforestated sense), but otherwise operating in the same manner.
  • the machine 12 is conveniently provided with a conventional control unit (not shown for simplicity), preferably of microprocessor type, which enables its operation to be controlled, aided by the presence of sensors provided, for example, to measure the distance between the uprights of the article in order to automatically determine the stroke of the first sanding means 20.1 and 20.2, to sense the presence of transverse corners in order to raise and lower the second sanding means 32.1 and 32.2 to prevent spoiling of these corners, to vary the speed of the various sanding means and in particular to decrease the speed of the third means 38 and when in correspondence with possible projections, and to incline the axes of rotation of the sanding means on the basis of the type of article to be sanded.
  • a conventional control unit not shown for simplicity
  • microprocessor type which enables its operation to be controlled, aided by the presence of sensors provided, for example, to measure the distance between the uprights of the article in order to automatically determine the stroke of the first sanding means 20.1 and 20.2, to sense
