Definitions

  • This invention generally relates to the art of surface preparation of workpieces and, particularly, to a scuffing machine for surface-finishing wood products such as cabinet doors and the like.
  • Machines have been designed for preparing surfaces of workpieces for various applications.
  • wood finishing machines have been used in attempting to smooth or polish wood products, such as cabinets doors and the like.
  • wood finishing machines have been provided as sanders which use an abrasive such as sandpaper in an attempt to finish the wood.
  • One type of sanding machine may use a sanding belt entrained around a sanding platen.
  • Some sanding machines use orbital sanding heads which are moved back and forth across the wood product abrading its surface.
  • Other sanding machines use finishing wheels which rotate on generally horizontal axes (i.e.
  • the wheels are fabricated of a plurality of layers of split edged sanding paper.
  • Still further sanding machines use a plurality of horizontal finishing wheels which rotate on horizontal axes, with the horizontal wheels, themselves, mounted on and rotate about a common, central vertical axis.
  • the wheels are fabricated of a plurality of layers of split-edged sanding paper.
  • the present invention is directed to solving these problems by providing a unique scuffing machine for wood products which uses a plurality of scuffing brushes having elongated bristles.
  • An object, therefore, of the invention is to provide a new and improved a scuffing machine for finishing the surfaces of continuously advancing wood products.
  • the machine includes a frame defining a scuffing station.
  • Conveying means are provided on the frame for transporting wood products to be finished through the scuffing station in a generally horizontal feeding direction.
  • a plurality of scuffing brushes are mounted on the frame at the scuffing station for rotation about vertical axes. The axes of some of the brushes are spaced transversely of the feeding direction. The axes of some of the brushes are spaced generally parallel to the feeding direction. Some of the brushes overlap transversely of the feeding direction to prevent transverse finishing gaps on the wood products.
  • Each scuffing brush includes a plurality of elongated, vertically extending bristles which terminate in distal ends for engaging the wood products.
  • the scuffing brushes are disposed in at least two generally parallel rows extending transversely of the feeding direction.
  • the axes of the brushes in one row are offset transversely of the axes of the brushes in the other row.
  • the adjacent brushes on transversely spaced axes include bristles which intermesh when the brushes are rotated.
  • the adjacent brushes rotate such that the outer peripheries thereof move in the same direction.
  • the bristles are on the order of 2-4 inches long.
  • the bristles are on the order of 0.20-0.050 inch in diameter.
  • the bristles are fabricated of an abrasive impregnated plastic material having an abrasion factor on the order of 80-240 grit.
  • the bristles herein are of a nylon/silicone carbide material.
  • the scuffing machine includes a cleaning station on the frame down-line of the scuffing station. At least one cleaning brush is located at the cleaning station, and the cleaning brush comprises a roller brush rotatable on a horizontal axis extending transversely of the feeding direction. Motor means are provided for rotating the scuffing brushes on the order of 100-500 rpm. A single motor is provided for conjointly rotating a plurality of the scuffing brushes.
  • a further feature of the invention is that the bristles of the scuffing brushes have proximal ends fixed to a base of the brush.
  • An elastic band is positioned about the brush around the proximal ends of the bristles to control outward flaring of the distal ends of the bristles.
  • the invention is embodied in a scuffing machine, generally designated 10, for finishing the surfaces of continuously advancing wood products, such as cabinet doors or the like.
  • a scuffing machine for finishing the surfaces of continuously advancing wood products, such as cabinet doors or the like.
  • the machine has been used very effectively to scuff the wood products between the sealing coat and the top finishing coat of a finished wood product, including cabinet doors having three-dimensional or contoured surfaces to be finished.
  • the scuffing machine of the invention is readily applicable for a wide range of finishing processes on wood products.
  • FIG. 1 and 2 best show that scuffing machine 10 includes a frame, generally designated 12, defining a scuffing station, generally designated 14, and a cleaning station, generally designated 16.
  • a conveying means in the form of an endless conveyor, generally designated 18, is provided for transporting the workpieces, such as the wood products, to be finished through the scuffing station and the cleaning station in a generally horizontal feeding direction as indicated by arrow "A" (Fig. 1).
  • the conveyor therefore, defines an in-feed end 20 of the machine and an out-feed end 22 of the machine.
  • the conveyor may be a vacuum conveyor having orifices to hold the wood products down on a conveyor belt as they continuously advance through the machine.
  • a vacuum system generally designated 24, is provided to effect the vacuum at the conveyor surface.
  • each cluster of brushes include two brushes in a front row (i.e. closer to in-feed end 20) and three brushes in a rear row.
  • All of the brushes in each cluster are driven by a common electrical motor 32 and an endless drive belt 34 which is trained around a plurality of pulleys or sprockets 36 fixed to rotating shafts 28.
  • the shafts are journalled in a frame plate 38 of frame 12.
  • cleaning station 16 is provided to remove the fine particles from the wood products resulting from the scuffing operation.
  • a pair of exhaust hoods 40 each have an outlet 42 which is connected to an appropriate vacuum source.
  • a horizontal roller brush 44 is mounted within each exhaust hood 40 for rotation on a horizontal axis 46.
  • Each roller brush has a plurality of fairly soft bristles for gentling wiping the surface of the finished wood products as the particles are lifted and exhausted through outlets 42.
  • a pair of electrical motors 48 (Figs. 1-3) are provided for rotating roller brushes 44 at the cleaning station.
  • Figure 7 also shows an electrical motor 50 for driving conveyor 18.
  • the brushes in the front row in each cluster are offset transversely of the feeding direction relative to the brushes in the second row.
  • This provides a continuous scuffing medium transversely of the entire surfaces of the wood products as they are continuously advanced by conveyor 18 through scuffing station 14 in the feeding direction "A".
  • FIG 9 shows a single scuffing brush 26 which includes its rotating shaft 28 projecting from the top thereof.
  • the shaft extends from a brush head, generally designated 60, through a bearing housing 62.
  • Each brush head 60 includes a plurality of elongated, vertically extending bristles 64 which terminate in distal ends 64a for engaging the wood products to be finished.
  • Proximal ends 64b of the bristles are attached or inserted into a circular base plate 66 which may be fabricated of wood, plastic or the like.
  • the circular base plate is fixed to a bottom end 28a of rotating shaft 28 by a bracket 68.
  • bristles 64 be on the order of 2-4 inches long.
  • the bristles are on the order 0.20-0.050 inch in diameter.
  • the bristles are fabricated of an abrasive impregnated plastic material, such as a nylon/silicone carbide material.
  • the bristles have an abrasion factor on the order of 80-240 grit. It is contemplated that motors 32 be able to rotate brush heads 60 conjointly on the order of 100-500 rpm, through drive belt 34 and pulleys or sprockets 36 described in relation to Figures 1 and 2.
  • Figure 9 also shows a feature of the invention in the form of an elastic band 70 which is mounted about circular base plate 66, as by a press-fit.
  • the arrangement and spacing of scuffing brushes 26 and the size of brush heads 60 are such that bristles 64 of adjacent brush heads in the transverse rows of scuffing brushes flare out during rotation, so that the bristles of adjacent brushes intermesh when they rotate.
  • drive belt 34 is trained around pulleys or sprockets 36 so that the peripheries of the adjacent intermeshed brushes rotate in the same direction.
  • Band 70 is fabricated of plastic or yieldable material so that it is flexible and can be used to control outward flaring of the bristles.
