Definitions

  • the present invention relates to a continuous through-feed grinding machine and method for machining a workpiece surface, said grinding machine having a grinding station with at least two rotating grinding tools, more specifically disc grinders or rolls.
  • discrete workpieces are transported on a conveyor system along one or several grinding stations in such type continuous through-feed grinding machines, said grinding stations being provided with abrasive discs and/or rolls to which abrasive paper is mounted in a lamellar fashion.
  • the abrasive discs or rolls thereby machine the workpiece, more specifically the profile thereof, from different angles in order to break possible edges and/or to remove burs.
  • a grinding station for a continuous through-feed grinding machine is known from DE 196 11 932 A1 in which four secondary rotation axes are provided on one primary rotation axis, four roll grinders being mounted to each secondary rotation axis.
  • the roll grinders thereby rotate about their horizontal axis and both the primary and the secondary rotation axes cause the roll grinder to rotate once more.
  • the respective one of the roll grinders is caused to move diffusely across the surface of the workpiece, the objective being to grind each point of the workpiece surface as far as practicable from different angles in order to make it possible to sufficiently grind even complex edges, profiles or other patterns.
  • a grinding station is known from WO 99/22905 in which a number of roll grinders is mounted to a vertical axis, the roll grinders rotating about their horizontal axis on the one side and about the vertical axis on the other side.
  • the surface of the workpiece is ground by the various grinding tools from different directions and angles.
  • the surface of the workpiece is not machined uniformly thereby. Accordingly, there are regions of the workpiece surface that are mainly contacted at a certain angle or that are machined at a high or a low relative velocity, which leads to different grinding results and to different wear of the grinding tool.
  • the oscillating movement across the direction of transport combined with the rotation of the grinding tool and the movement of the workpiece, causes the grinding tool to move relative to the surface of the workpiece in a manner that is locally very irregular.
  • the invention proposes a continuous through-feed grinding machine according to the features of claim 1 or the features of claim 5 .
  • Advantageous developed implementations of this continuous through-feed grinding machine will become apparent from the subordinate claims.
  • a continuous through-feed grinding machine formed in accordance with this technical teaching has the advantage that the endless path permits to achieve a defined movement of the grinding tools over the workpiece surface, said grinding tools being at all times evenly guided over the surface of the workpiece so that even machining of the workpiece surface and even wear of the grinding tools are achieved.
  • This defined movement may be used by the machine upsetter to place the various workpieces on the conveyor in accordance with their profile in such a manner that they are optimally contacted with the grinding tools, thus ensuring thorough grinding.
  • the endless path is dimensioned such that only a portion of the endless path is located in the region of the expected workpiece surface whilst another portion of the endless path is disposed outside of the workpiece surface.
  • the endless path is advantageously configured in such a manner that those segments of the endless path in which the grinding tools are moved linearly or almost linearly are disposed above the expected workpiece surface, more specifically above the conveyor, whilst those portions of the endless path that are sharply curved or in which the workpieces are merely transferred are disposed outside of the expected workpiece surface. As a result thereof, the grinding tools are moved exclusively or almost linearly over the workpiece surface.
  • the grinding tools may thereby be left open whether the grinding tools are moved along the direction of transport of the workpieces or across thereto or at an angle of between +45° and ⁇ 45° to the direction of transport. In any case, uniform movement of the grinding tools is achieved through the linear movement in the region of the grinding process.
  • the grinding station includes a guide rail configured to conform to the endless path and on which a number of carriages are guided, each carriage in turn holding one grinding tool.
  • a gear rim is held on the guide rail, said gear rim cooperating with a gearwheel mounted to the grinding tool so that the grinding tool rotates about its vertical axis as long as the carriage is moved forward.
  • the rpm of the grinding tools is thereby coupled to the revolving velocity of the grinding tools along the endless path.
  • each grinding tool is driven by its own electric motor.
  • the grinding tools may likewise be operated at much higher speed.
  • Another advantage is that, as a result of the higher rpm of the grinding tools, the entire grinding process is completed sooner, which increases the throughput.
  • the grinding tools are individually controllable. This has the advantage that, depending on the required grinding conditions, the grinding tools may be connected on or off or their speed may be adjusted or they may be operated in the desired direction of rotation, which makes it possible to optimally adjust the grinding process to the requirements of the workpiece.
  • the grinding station is equipped with disc grinders only since these offer advantages in the multi-sided machining of workpieces.
  • the grinding station is equipped with roll grinders only since these allow for more aggressive machining.
  • Such type machining is particularly advantageous for deburring metal pieces.
  • the grinding station is provided with both disc grinders and roll grinders.
  • the roll grinders may thereby be disposed with their rotation axis in the infeed direction, across the infeed direction or at any angle, more specifically at an angle of 45°, to the infeed direction. This has the advantage that the grinding station may be adapted to the workpieces to be ground in order to achieve the best possible grinding result with, as far as possible, even wear of the grinding tools.
  • Another advantage is that a desired grinding pattern can be achieved by individually arranging the grinding tools. This grinding pattern may thereby be oriented in the direction of the set angle of the angle grinder but may also be diffuse if different grinding tools are being utilized or if the grinding tools are differently aligned.
  • the grinding station is equipped with three identical groups of grinding tools, each group of grinding tools including one disc grinder, one roll grinder mounted in the infeed direction, one mounted across the infeed direction and one inclined at an angle of 45° to the infeed direction.
  • each group of grinding tools including one disc grinder, one roll grinder mounted in the infeed direction, one mounted across the infeed direction and one inclined at an angle of 45° to the infeed direction.
  • Another advantage is that while the workpiece is so thoroughly and completely machined the transport speed of the workpiece may be increased without compromising the machining quality. This increased speed results in greater throughput and in greater profitability of the continuous through-feed grinding machine of the invention.

After the surface of these workpieces 112 has been mechanically machined, it must be ground in order to remove burs and protruding wood fibers and to smooth the surface. Depressions and raised portions such as for example milling cuts, mounted ledges or the like which are oriented across or along the infeed direction or at any angle thereto should thereby also be ground uniformly as far as practicable.

  • a gearwheel 134 that meshes with a gear rim 136 mounted to the inner side of the guide rail 130 is mounted to the vertical axis 124 .
  • This gear rim 136 -gearwheel 134 -combination causes the grinding tool 122 to rotate about its vertical axis 124 as soon as the disc grinder 122 is advanced.

Moreover, it is thus achieved that the disc grinders 122 are caused to move over the workpieces 112 at a uniform speed so that machining of the workpiece surface is perfectly uniform.
  • the surface of the workpiece is optimally ground across the direction of transport and by having the disc grinders 122 rotating about their vertical axis 130 the workpiece 112 is also ground at a great variety of different angles.
