Definitions

  • the invention relates to a method and an apparatus for one or two-sided lateral leveling by rotating with a processing machine Leveling tools (such as grinding wheels or milling cutters), with essentially functional surfaces assigned to the end face, transported dried Brick moldings and / or fired bricks.
  • a processing machine Leveling tools such as grinding wheels or milling cutters
  • the invention has for its object an improved method and an improved device (machine) for one- or two-sided Leveling bricks or bricks to create, at or which is a quick way of working and still a true to size Work is guaranteed.
  • dimensionally stable bricks are always produced, whereby true-to-size grinding (or milling) regardless of the finished dimension Bricks (moldings) occur and there are no gaps in the product sequence have a negative impact. If the grinding or milling tool is worn out immediately the required tracking (re-adjustment), because according to the invention the machining front edge of the grinding wheel or milling cutter without contact is measured (measured) and if there is any deviation from the Target position is immediately brought into the target position - this is on Start of each work after a tool change and / or after a Maintenance and repair work of great benefit.
  • the invention is also distinguished from the prior art from that, in a preferred and advantageous manner, the leveling tool feed movement recorded and taken into account for the leveling tool wear measurement becomes.
  • the invention is intended for face brick production, it can also be used other building blocks, such as pumice stones, refractory stones (firebricks), tiles and The same can be processed laterally (leveled / calibrated).
  • the invention is both the claimed method and the claimed Device claims and the graphic representation and their description refer to.
  • the machine according to the invention is designed as a grinding machine.
  • the invention can also be realized on a milling machine. With this machine, either dried bricks Z or fired brick Z leveled on at least one side. Is particularly preferred the two-sided and therefore calibrating processing.
  • the machine according to the invention works in a continuous process.
  • the adjusting device J which the to be processed, in particular to be ground bricks (shaped articles) Z automatically brings it into a position required for processing (centered).
  • the adjusting device J consists of two lateral, vertical Flat revolving conveyor belts, the front (inlet side) ends diverge to form an inlet funnel (see FIG. 2).
  • the bricks (moldings) Z are from on a machine frame 1 - with base (element) 1a and both ends Stands 1b - arranged conveyor 2 and pressing device 3 detected and clamped in height in an adjusted position and in such Position moved through at least one leveling station 4, 4 'and on at least one side, preferably on both sides, by means of a grinding wheel or grinding head (similar to a milling head) 5 processed, in particular calibrated planed.
  • the leveling tools (such as grinding wheels or milling cutters) 5 are essentially their end face 5a associated functional surfaces. They rotate around an essentially horizontal axis. Your drive is numbered 5b.
  • the Entire functional unit (disc + drive) is horizontally displaceable (see FIGS. 2 and 3).
  • Tool unit including drive 5b to a large extent - i.e. so far that the Grinding wheels are easily accessible from their front side 5a - to the outside relocatable (especially displaceable). This displaceability extends far beyond beyond what is required for bringing it out of service.
  • the leveling tools 5 including drive are used for maintenance and repair work 5b moved so far outwards that the pressing device 3 or the pressing device 3 plus conveyor 2 also in the otherwise of the / Leveling station (s) 4,4 'occupied area freely accessible and if necessary can be lifted upwards. Let such maintenance and repair work with the machine according to the invention at a leveling station 4/4 ' running machine, i.e. when operating another leveling station (s) 4 '/ 4, carry out.
  • the leveling station 4 or 4 'required for the operation is in the required Dimension set to the brick center plane (vertical plane of symmetry).
  • the continuous bricks (shaped articles) Z are always precisely dimensioned ensure the positions of the free-end faces 5a of all planner tools 5 during processing (planning and / or calibration process) continuously or at wear-preselected intervals by means of optical Measuring device 6,6 'monitored contactlessly, the actual position in each case compared with the target position and the result converted into control impulses is, which in control engineering coupling of the respective measuring device 6/6 'with the associated leveling tool shifting drive for leveling tool shifting (Tracking) is used.
  • the leveling tools 5 if necessary, i.e. in the event of a deviation from the one to be processed Brick (molding) Z facing end face 5a from the target position, below Maintenance of the machining process (grinding or milling process) automatically set / tracked to the target position.
  • Each measuring device 6,6 works with a light beam (bundle) 6a, which during leveling in the area of each leveling leveling tool end face 5a while being outside the path of movement of the one to be processed Brick / brick form Z runs at right angles to the axis of rotation and the circulation circle as secant and along the vertical through the "target dimension" Plane intersects.
  • Each light beam (bundle) 6a is at least one light receiving one Sensor assigned, the light and shadow signal for the Position detection of the front side 5a and leveling tool tracking used becomes. At least two sensors are particularly preferred (Receiver cells) available.
  • Fig. 3 one can Two-station machine due to its own measuring equipment for each Leveling tool 5 worked in two stages (especially so-called roughing and Precision work).
