Definitions

  • the invention relates to a machine for the lateral leveling of brick and refractory products, especially for the calibration of building blocks, according to the preamble of Claim 1.
  • Such a machine is known from DE 296 11 728 U1. With such a machine can stones or blanks of very different widths to a desired one Be ground to size using a single conveyor belt with a fixed width would be possible at most to a very small extent - cf. see page 3, paragraph 2 there is still the disadvantage that the machine's own transport system is susceptible to wear and tear is relatively noisy and causes a lot of maintenance. Total results a construction with more frequent downtimes and an uneconomical concept. Despite considerable effort in the chain guide, there is an adverse game what the Work quality of the machines significantly impaired.
  • the invention has for its object an improved generic machine - which can be adjusted to different sized calibration dimensions - to create their machine's own transport system is designed to be low-wear and free of play, requires little maintenance and works quietly and the block to be processed or the like both sides of the transport path run exactly synchronously, and therefore tilt-free, promoted.
  • the conveyor elements of the machine Transport system formed by flexible endless belts, with its promotion effective strand in the area that is crucial for the quality of the finished product of the leveling tools exactly in the lateral position as well as in the height direction are positively driven and driven without slip due to the toothed belt profile are and ensure synchronism of the individual belts of the conveyor - so a position-accurate, play-free run of the face brick to be leveled, face brick blanks or the like. Is achieved by the leveling station or leveling stations.
  • the machine's own Transport system ensures that the object is clamped properly positionally stable, that is, in the relative position immovable, support points.
  • a machine according to the invention for the lateral leveling of brick and Refractory products, especially for the calibration of building blocks 1 (or building block blanks), their transport width and / or calibration dimension in a larger one Measuring range varies can be designed as a grinding machine and / or milling machine his.
  • a particularly preferred training as a face brick grinding machine enables adjustment of caliber dimensions / grinding widths with two-strand object support in the range of about 300 - 500 mm.
  • one machine according to the invention also for larger working widths, for example up to 800 mm.
  • the conveyor device 2a is at least divided in terms of width and has object-carrying, with 4 numbered belt drives, which are transverse to the transport direction are relocatable and held adjustable to different spans.
  • the holding-down device 2b has at least one circumferential conveyor element with 5 numbered belt drive, which is at a vertical distance from Conveyor 2a is adjustable according to the target size of the object height as well acts on the object 1 to be planed or calibrated under pressure.
  • the or each leveling station 3 has, in addition to the machine's own transport system 2 at least on one side, in particular on both sides and lying flush opposite, a driven, to a calibration dimension dependent set position sideways (in with respect to the transport direction T) movable leveling device by a with 3a numbered (and driven by its own drive 3b) grinding head, one Grinding wheel, a grinding belt or a milling head can be formed.
  • the drive rollers 8 of both conveyor belts of the conveyor 2a are Rigidly coupled all around. This can be done via a mechanical shaft (e.g. spline, preferably ball spline) or a so-called. electric wave (e.g. synchronous synchronous drives); the mechanical is shown Solution, wherein the drive and connecting shaft is numbered 9.
  • a mechanical shaft e.g. spline, preferably ball spline
  • electric wave e.g. synchronous synchronous drives
  • the hold-down device 2b has one with the one to be leveled / calibrated Module 1 interacting conveyor belt, especially so-called. Kraftband on which is provided with longitudinal keyways on the back.
  • a spring-loaded wedge profile roll 10 and the two side areas can run over abutment-forming slide rails.
  • the conveyor belts of the conveying device 2a and hold-down device 2b have elastic longitudinal strips 12 on the surface interacting with the module 1 that act as a buffer. They run through a band encapsulation 13.
  • the two conveyor belts of the conveyor device 2a which is divided in two parts, are each arranged on the adjacent machine table and thus by adjusting the machine table adjustable to the required span.
