Definitions

  • the invention relates to a method and an apparatus for grinding the base surfaces of ceramic articles such as plates, bowls and the like with a round, rectangular or oval shape.
  • the device according to the invention is intended for processing, in particular for grinding large ceramic articles such as plates, bowls and the like, which, because of their size, are provided with a counter foot or web, which is formed in addition to their normal foot.
  • This counter foot must be attached with the appropriate article size, otherwise the central area will sag downwards in the event of fire.
  • the articles had been passed by hand over a demolition table, where both the foot and the counter foot were ground flat on a flat surface that was covered with an abrasive. This created sharp-edged surfaces that always caused scratches when using the articles on tables and on the tops of the articles when stacking.
  • the invention is therefore based on the object of providing a method for grinding ceramic articles and a device suitable for carrying out the method, by means of which all foot shapes can be ground.
  • both the foot and the counter foot or web are ground together in one station or, if appropriate, in two successive ones, and the articles and / or the abrasive is eccentric at least during the grinding of the counter foot rotate.
  • the task relates to the device, it is achieved according to the invention by one or more stations with grinding tools for grinding the feet and / or counter feet, workpiece holders which hold the articles on the edge or on the side opposite the foot, at least one tool holder which is in the Station for grinding the counter feet is attached eccentrically to its drive shaft.
  • the arrangement of the grinding device for the counter foot 16 in front of all other grinding stations has the purpose that the grinding residues occurring here in the center are conveyed to the outside by the rotation of the articles and the centrifugal force thus occurring during the subsequent operations.
  • carriers 20 are provided, to which the grinding tools are fastened by means of screw connections.
  • FIGS. 2 and 3 represent the station II , in which a grinding device for the counter foot 16 is provided.
  • the plates rest on workpiece holders 14 , which can be formed from metal or plastic. Either vacuum that is generated via the line 22 of the shaft 24 in the space 26 or via ensures that the plates 12 are firmly seated on the workpiece holders 14 for example a possibly elastic edge 28 which holds the plates.
  • the workpiece holder 14 is arranged here, for example, eccentrically with respect to the axis A of the shaft 24 .
  • the grinding belt 30 rests on the counter foot 16 .
  • the sanding belt 30 advances by a length which is dependent on the length of the counter foot.
  • grinding belt 30 is unwound from one spool 32 and wound onto the spool 34 which interacts with it, both of which are fastened to the carrier 20 .
  • the piston cylinder unit 36 with which the height for the grinding block 38 can be roughly adjusted, is also seated on the carrier 20 .
  • the height and contact pressure fine adjustment for the sanding block 38 is based on the tension spring 40 , which sits at the end of the rod 42 , at the other end of which a vibrator 44 is located as an intermediate member to the sanding block.
  • the vibrations generated by the pneumatic vibrator 44 increase the grinding effect of the grinding belt, the contact pressure of which can also be varied from the adjusting screw.
  • the elastic pad 46 includes the counter foot edges during grinding, whereby the grinding belt creates 30 round transitions.
  • Fig. 3 shows the grinding station II shown in Fig. 2 with the plate 12 rotated by 180 ° , so that the counter foot 16 is shown in cross section.
  • the workpiece holder 14 is mounted on the shaft 24 offset from the axis A. The same effect would result in an eccentric position of the plate on the workpiece holder 14 .
  • Guide rollers 48 are shown on the left and right of the vibrator 44 .
  • the station II shown in FIG. 4 is almost identical in construction to the stations III and IV. This station is set up for grinding the plate foot 17 , for which a grinding belt 30 transported in cycles is also used.
  • an elastic roller 50 is provided for this purpose, which presses the grinding belt 30 against the plate foot 17 and thus simultaneously processes the standing surface and the edges.
  • the length of the roller 50 is based on the diameter difference of the plate base 17, which can be considerable in the case of oval and almost rectangular plates 12 .
  • the entire grinding station with a spring (not shown) is able to adapt to the changed height level.
  • inclining the roller 50 This is done by adjusting the screw 52.
  • the roll 50 is shown tilted to the left here. Likewise, however, the roller can also be inclined to the right if this becomes necessary by changing the direction of rotation of the workpiece holder 14 or by processing other articles with special foot shapes.
