Definitions

  • the invention relates to a device for removing the inner and outer ridges provided on the contour of a one-level leather-hard ceramic molded article, in particular the handle of a ceramic article, such as a cup, a cup or the like, the device having a cleaning tool with an inner surface. and outer ridge has complementary inner and outer plaster contour.
  • Such a device is for example from the DE 41 29 663 C1 known.
  • the cleaning tool is moved back and forth perpendicular to the contour with respect to the molding and a force is exerted between the molding and the cleaning tool with respect to the direction of reciprocating relative movement in the corresponding radial plane determined by the ceramic molding whose direction in this plane is progressively changed by 180 ° during the reciprocating relative movements.
  • This progressive change in the force to be exerted requires one elaborate control of the cleaning tool.
  • Another shortcoming of this known device is that the deburring can still leave nothing to be desired, especially at angular transition sections of the respective ceramic molding.
  • the DE 21 61 853 A discloses a device for removing the burr of a leather-hard ceramic molding, ie for cleaning, in particular, handles of leather-hard ceramic articles.
  • This known device has a provided with pairs of tools, rotatable and lowerable holder and a holder associated with turnstile with holding devices for the ceramic objects to be cleaned.
  • the handles are provided on webs, which are designed such that the to be cleaned inner and outer contours of the handle are freely accessible.
  • Each pair of tools consists of two shaped according to the shape of the handle foam profiles, of which the inner foam profile is mounted on a core and the outer foam profile is enclosed by a holder, wherein the foam profiles include a space whose dimensions are slightly smaller than that of the handle to be cleaned.
  • the pairs of tools are mounted on a holder that can be moved up and down along a guide perpendicular to the direction determined by the plane of the handle. If the pairs of tools are lowered with the holder, then the pairs of tools along and outside of the respective, held handle along and remove, ie smooth the burrs. However, a risk of breakage of the respective leather-hard ceramic molding, in particular handle, can not be reliably excluded.
