Definitions

  • the invention relates to a machine for the lateral processing of building blocks, in particular dried brick moldings or fired bricks, which are adjusted and transported in height between endless rotating conveying elements by at least one processing station with a lateral tool arrangement.
  • the objects to be machined laterally are transported clamped in the machine's own transport system between conveyor elements, which are either formed by chains or attached to chains. Because of the chains, there is a lot of wear and, due to the chain play, there is also an imprecise and therefore poor lateral guidance, i.e. lateral guidance, the cuboid to be machined. However, an exact position of the cuboids to be machined, in particular dried brick moldings or fired bricks, in relation to the side machining tools is necessary for the work to be carried out correctly (i.e. those with small dimensional tolerances).
  • the dreams interacting with the tiles run at a height distance which is smaller than the thickness of the tile to be processed, so that a vertical pressure is exerted on the tiles which prevents the tiles from shifting laterally during processing.
  • This system designed for grinding tiles, i.e. thin and light objects with a small side surface, is unsuitable for side processing, especially surface grinding, of thicker or taller as well as heavy objects such as building blocks (in particular dried bricks or fired bricks) - that
  • the known transport system does not guarantee non-slip object clamping when processing with large lateral forces and is unable to transport heavy building blocks in the required exact position.
  • the invention has for its object to provide an improved machine of the type mentioned, in which the laterally to be leveled blocks despite great thickness (or height in relation to the transport level) compared to tiles or shingles - and thus processing with large lateral forces - Safe in a once adjusted position, ie is fixed non-slip and can be transported in such a position immovably through at least one processing station.
  • the conveyor elements of the machine's own transport system are formed by flexible endless belts, which with their strand acting on the object to be machined are both one achieve exact lateral position as well as an exact flat position.
  • the machine's own transport system brings about a perfect block clamping with functionally stable position, i. H. in the relative position to the building block, support points.
  • the spring-loaded wedge profile rollers ensure play-free centering and belt side guidance in the area where the exact transport element side position is important.
  • the spline rollers in the subject matter of the invention only need to carry out the belt side guidance (by adjusting the belt splines).
  • the carrying and hold-down function of the conveyor elements is carried out in the machine's own transport system by the slide rails, over which the flexible endless belts run with their side areas.
  • belt sagging is avoided even when transporting heavy objects and an exact height of each transported building block is ensured when passing through the leveling station (s).
  • the building blocks to be leveled on the side are fixed by clamping alone and guided through the leveling station in the correct direction.
  • the machine according to the invention can be designed as a grinding machine and / or milling machine. It is preferably intended for the lateral processing of dried brick moldings and / or fired bricks - of course, other products of the building materials industry, for example pumice stones, refractory stones (firebricks), tiles, can also be processed with them.
  • the machine according to the invention for the lateral processing of building blocks or the like is preferably designed as a grinding machine.
  • the concept according to the invention can also be implemented on a milling machine. With this machine, either dried brick moldings Z or fired bricks Z are leveled on at least one side during the production of the facing bricks. Two-sided and thus calibrating processing is particularly preferred.
  • the machine according to the invention works in a continuous process.
  • It has a machine inlet formed by an adjusting device J, which automatically brings the objects to be processed, in particular to be ground (such as bricks or brick moldings Z) into a position required for processing (centered).
  • an adjusting device J which automatically brings the objects to be processed, in particular to be ground (such as bricks or brick moldings Z) into a position required for processing (centered).
  • the bricks (moldings) Z which are centered when they enter the machine's own transport system, are gripped by a conveyor 2 and pressing device 3 arranged on a machine frame 1 - with a base (element) 1b and both ends of stands 1a and clamped in height in an adjusted position and in such a position moved through at least one leveling station 4 and processed on at least one side, preferably on both sides, using leveling tools 5 designed as a grinding wheel or grinding head (similar to a milling head), in particular calibrated leveling.
  • leveling tools 5 designed as a grinding wheel or grinding head (similar to a milling head), in particular calibrated leveling.
  • the leveling tools (such as grinding wheels or milling cutters) 5 are provided with functional surfaces which are essentially assigned to their end face 5a. They rotate around an essentially horizontal axis. Your drive is numbered 5b. The entire functional unit (disc + drive) can be moved horizontally.
  • a non-contact measuring device is preferably present, which detects the machining end face 5a of each leveling tool 5 and whose signals are used for automatic leveling tool tracking.
  • the invention ensures that the bricks (shaped articles) Z remain in their lateral relative position specified by the adjusting device J also during the entire machining (grinding or milling).
  • the transport system is formed by two pressure-loaded endless belts made of flexible material, designed as a conveyor and pressure belt 2, 3, which are positively guided in the lateral position by means of at least one centering keyway-V-ribbed connection and at least in the area of the processing performing leveling tools (s) 5, in particular grinding wheel (s), run over a rail-like or plate-like flat abutment 9.
  • the conveyor belt 2 and the pressure belt 3 are provided on the back at least in the central cross-sectional area with splines 7a, in which spline rollers 8, as centering rollers, engage.
  • two slide strips 9 are provided which act on the two side areas.
  • the endless band material is designed as a so-called force band and has splines 7a and V-ribs 7b on the back.
  • the spline rollers 8 are spring loaded. 6 and 7, the spring elements shown symbolically are numbered 10.
  • each spline roller bearing is cushioned by means of a spring assembly and is arranged in a guided manner at the same time - this saves additional guide elements.
  • the pressing device 3 (in particular a so-called pressure belt 3) can be adjusted in the position relative to the conveyor belt 2 - and is accordingly arranged in a height-adjustable manner - and is supported in a spring-loaded manner as a whole.
  • conveyor belt 2 and pressing or holding-down device 3 are each detachably arranged as a complete “assembly unit” on the machine frame 1 or a part associated therewith, in particular holder 11.
  • These assembly units are marked in FIG. 1 by means of cross hatching. They have elements 15, 16, 17 of a plug connection, namely those for adjustment / position fixing (position 15), locking means 16 (eg screws) and an electric coupling 17.
  • the downtime in the event of maintenance and / or repair work can be reduced to a minimum if the device (s) present in the machine are dismantled 2/3 and replaced by a replacement unit .
