Definitions

  • the invention relates to a grinding device for grinding flat grinding material with the features of the preamble of claim 1.
  • This surface grinding machine has a rotating grinding device with brushes for the underside of the flatware, which is arranged at a fixed angle to the underside of the flatware.
  • a rotary and feed device with an integrated vacuum system for grinding machines has a suction head which is rotatably mounted via a first drive device and which is height-adjustable by means of a second drive device and is arranged on a base device.
  • DE-A-10 2016 111 745 shows a grinding device with grinding rollers which are fixed at a fixed angle during the grinding process.
  • a sanding belt is also provided which is not driven during the sanding process.
  • the object of the present invention is to provide an improved device and an improved method for grinding ceramic articles, in which a high-quality grinding around a base of the ceramic part can be achieved.
  • the solution according to the invention is a grinding device for grinding feet of grinding material, preferably flat ceramic articles or porcelain articles.
  • the grinding device has a grinding roller having a grinding drive, the grinding drive operating the grinding roller during of grinding drives rotating about an axis of rotation, as well as with a feed device having a linear drive and a rotary drive, which feeds the flat material to be sanded to the grinding roller in such a way that a foot of the material to be sanded comes into contact with the sanding roller. It is essential that the grinding roller, starting from an initial position, is mounted so that it can be tilted about a tilting axis against a restoring force.
  • the base of the material to be sanded is sanded over a larger, predefined product-related area, right into the outside of the base.
  • a round sanding of the foot and thus a regrinding of the foot is possible without a high pressure on the sanding belt.
  • the restoring force of the sanding roller determines the sanding pressure and thus the pressure on the sanding belt.
  • the restoring force can preferably be adjusted or set in order to achieve an optimal grinding result.
  • the tilting movement and the low contact pressure increase the service life of the sanding belt.
  • the low contact pressure also enables the use of different abrasives, such as Diamond bands or polishing agents, as e.g. are available under the trade name Scoth Bride.
  • the tilting movement also causes a relative movement between the material to be sanded and the sanding belt, so that different areas of the sanding roller are used for sanding. This increases the service life of the abrasive.
  • the advantage of a grinding roller rotating during the grinding process is that the risk of the grinding roller overheating at certain points is reduced. Cooling with a cooling liquid is not necessary, so that the grinding process can also be carried out using dry grinding. A subsequent drying of the material to be sanded is therefore not necessary.
  • Ceramic items or porcelain items can be used as grinding material.
  • plates and / or platters and / or bowls and / or cups can be used as the grinding material.
  • Both round ceramic articles or porcelain articles and non-circular ceramic articles or porcelain articles can advantageously be ground.
  • the material to be ground can be designed as a preferably flat material to be ground which has a foot on its rear side.
  • the solution according to the invention is a method for grinding feet of grinding material, preferably flat ceramic articles or porcelain articles, whereby a grinding material is rotated via a feed device and a grinding roller is fed in a straight line in such a way that a foot of the grinding material comes into contact with the grinding roller.
  • the grinding roller is driven to rotate during grinding. This reduces the risk of the grinding roller overheating at certain points.
  • the infeed device starts the infeed movement after the maximum stroke has been reached reversed and the grinding roller is tilted back in such a way that the foot of the material to be ground is also ground during the return movement. This means that the base of the material to be sanded is ground twice, so to speak.
  • the infeed movement can take place in two stages, in that the material to be sanded is fed in a first step via an infeed movement up to just before the sanding roller so that the foot of the material to be sanded does not yet touch the sanding roller, and that in a second step Step, a grinding stroke is carried out up to the maximum stroke and back again.
  • the infeed movement of the first step can take place faster than the lifting movement of the second step.
  • a control device for automatically controlling the linear drive and / or the rotary drive, the control device controlling the linear drive in such a way that the linear drive tilts the grinding roller during grinding by moving the material to be grinded in the direction of the The grinding roller is moved until a certain maximum stroke is reached and then moved back until the grinding roller reaches its initial position.
  • the maximum stroke is dimensioned in such a way that the surface of the grinding roller is at a distance from a glaze mirror of the material to be sanded at the maximum stroke. This has the effect that the grinding roller does not reach a glaze mirror of the material to be sanded, but nevertheless grinds a sufficient area of the foot.
  • the maximum stroke can advantageously be determined on an article-specific basis or specified on an article-specific basis.
  • the maximum stroke as a parameter for controlling the delivery device can be stored article-specifically.
  • the axis of rotation of the grinding roller and / or the outer edge of the grinding roller that is effective during grinding runs essentially parallel to a rear side of the material to be ground in the starting position. It can preferably be provided that the axis of rotation of the grinding roller and / or the outer edge of the grinding roller that is effective during grinding extends in the starting position at an angle of plus minus 3 ° to the rear of the material to be sanded. With a minus or a negative angle, the inside of the foot of the material to be sanded can be abraded.
  • the grinding roller overlaps an axis of rotation of the grinding material.
  • the axis of rotation of the material to be sanded is set up by an infeed device axis of rotation around which the material to be sanded is rotated by the rotary drive.
  • linear feet of a material to be ground can also be ground.
  • a sensor device for measuring the maximum stroke.
  • the maximum stroke can be predetermined or predeterminable.
  • a specific maximum stroke can be set via a setting device or an operating device can be entered.
  • the sensor device can be connected to the control device so that the control device automatically controls the grinding process.
  • the sensor device has a displacement measuring system which measures the stroke of the linear drive.
  • the Position measuring system can be integrated in the linear drive or it can be configured as an external position measuring system.

  • a method for setting up the grinding device according to the invention is carried out before the actual grinding. It is essential that before a grinding process a material to be sanded is manually controlled by means of the feed device and fed to the sanding roller so that the sanding roller tilts until the surface of the sanding roller has a desired minimum distance from a glaze mirror of the sanding material, and that this stroke of the Delivery device is stored as an article-specific maximum stroke.
