Definitions

  • the present invention is related to a device for processing substantially flat workpieces, said device comprising a transport surface for transportation through the device of each of the workpieces, and a processing unit, comprising a processing element having an abrasive surface and which is moveable parallel to the transport surface in order come into contact with each of the workpieces to be processed, a driving shaft and a carrier connected thereto for supporting the processing element, the driving shaft being transversely positioned on the carrier.
  • processing is taken to mean, among others, the deburring, grinding and sanding of substantially flat workpieces.
  • Semi-finished products punched or laser-cut from plate material are deburred at the edges or polished on the surface with the aid of the device described above.
  • the device of US 4,704,823 hereto comprises a processing disc which rotates in the horizontal plane under which a workpiece is transported.
  • a drawback of said known device is that the workpiece is processed only on the side which is located parallel to the processing disc.
  • the object of the present invention is to provide an improved device which is capable of multi-sided processing of substantially flat workpieces, including the removal of the oxide layer on the edge of the plate material as a result of laser cutting.
  • the device according to the invention is characterised in that the processing element comprises support members for supporting the abrasive surface, said support members being positioned at an angle of less than 90° with respect to the processing element.
  • the support members are at least radially directed with respect to the driving shaft of the carrier.
  • the abrasive surface has a much longer life cycle.
  • a processing element provided with radially, or at least partly radially directed support members is much less susceptible to wear.
  • the support members are preferably substantially inclined towards and/or away from the driving shaft in order to reinforce the processing effect.
  • the processing element comprises brush hairs as support members. Experimentally it has been found that brush hairs which are not at right angles with respect to the processing element have a high impact on the side of the workpiece, with a sufficient processing result as a consequence.
  • the brush hairs may be impregnated with abrasive particles or themselves be made of steel, preferably stainless-steel, in order to obtain an abrasive surface.
  • the surface of the processing element with support members not positioned at right angles can be combined with already known processing surfaces, such as a web of nonwoven synthetic fibres provided with sanding grains, which material is sold under the name Scotch-Brite, or brush hairs, impregnated met abrasive particles, positioned at right angles with respect to the transport surface.
  • processing surfaces such as a web of nonwoven synthetic fibres provided with sanding grains, which material is sold under the name Scotch-Brite, or brush hairs, impregnated met abrasive particles, positioned at right angles with respect to the transport surface.
  • the processing element further comprises brush hairs, placed between the support members at right angles to the processing element, which are preferably made of nylon. Said nylon hairs are provided to press the workpiece against the transport surface in order to prevent it from shooting away.
  • the processing element is formed by at least one flat round disc, while the carrier is capable of being rotationally driven, the multi-sided processing of a workpiece, such as described in US 4,704,823, is assured.
  • the diameter of the disc is preferably greater than the width of the transport surface, so that each workpiece will be processed by the abrasive surface of the processing element in at least two directions, regardless of the position of the workpiece on the transport surface.
  • the processing element is preferably removably connected to the carrier in order to allow the disc to be replaced in the event of wear of the abrasive surface.
  • the invention is also related to a processing element for application in a device for processing substantially flat workpieces according to the invention.
  • Figure 1 shows a device for processing flat workpieces 1.
  • the device comprises a conveyor 2 for transporting the workpieces 1 through the device.
  • the conveyor 2 comprises a transport surface 4 on which the workpieces 1 rest during transport through the device.
  • a processing unit 3 is arranged above the conveyor 2 and consists of a rotatable disc 5, parallel to the transport surface 4, with an abrasive surface which contacts each of the workpieces 1 to be processed.
  • the processing unit 3 comprises a rotationally drivable carrier 6 for supporting the disc 5 in rotation.
  • the brush hairs 7 have various orientations, that is to say, inclined towards and away from the rotational axis.
  • the brush hairs 7 are preferably of stainless-steel. Experiments have shown that stainless-steel brush hairs provide the desired effect, that is to say, a high impact on the side of the workpiece with a sufficient processing result as a consequence.
  • nylon hairs 8 have been placed on the disc 5 between the brush hairs 7 and at right angles to the transport surface 4.
  • FIG 3 the effect of the brush hairs 7 not being placed at right angles with respect to the transport surface 4 is shown.
  • the tops of the brush hairs 7 will have an impact on the side 9 of said workpiece 1, before being bent aside by the edge 10 of said workpiece 1.
  • the brush hairs 7 not placed at right angles have a high impact on the side 9 of said workpiece 1, with a removal of the oxide layer resulting from laser-cutting as a consequence.
  • abrasive surface can be placed on the support element directly, for example by impregnating the support element with abrasive particles. It is also possible to have a strip or piece of abrasive material run along each support element. Another example is brush hairs provided with a thickening at the outer end, with which they come into contact with the surface to be processed in order to achieve a wear effect.
  • the carrier 6 is rotationally driven and the processing element follows the rotational movement.
  • the processing element can also carry out a translational movement or a movement of another kind, for example a rotational movement as well as an oscillating movement.
