Definitions

  • the invention relates to an improved automatic control machine intended to be used in the ceramic industry.
  • the invention particularly relates to an automatic machine which was devised for carrying out the so-called “selection" of flat ceramic articles, such as ceramic tiles or slabs.
  • the invention refers to a machine which is predisposed for performing, on the tiles, at least a geometric control (or “linear measurement”), as well as a flatness control.
  • the sorting machines may be located upstream of end stations, wherein the tested articles are separated, thereby forming homogeneous groups or, as is usually said, the tested articles may belong to the same "selection group".
  • the control machines comprise a cabin, wherein the optical control devices are located and a conveyor which passes through the cabin and essentially consists of two parallel belts driven by respective motors.
  • the two belts support the articles and convey them continuously within the cab, wherein they are tested and thereafter conveyed towards the end of line, downstream of the machine.
  • the two belts are movable horizontally such that the reciprocal distance may be adjusted based on the different sizes of the articles to be tested.
  • a first drawback relates to the flatness control of ceramic articles, in particular tiles.
  • This control is aimed at checking flatness of the tested tile following laying thereof on floors or coverings.
  • the tiles When freely resting on the conveyor belts, the tiles, especially slim and long sized tiles as already mentioned, tend to bend due to gravity.
  • the known conveyor system requires the perfect parallelism of the two belts, in that, even mild convergences or divergences have the effect of producing a rotation of the tiles during transport, which affects the reliability of the measurements performed by the machine.
  • the technical task at the base of the present invention is to provide a control machine which overcomes the drawbacks of the known art mentioned above.
  • the machine 1 herein provided is intended to perform control operations automatically.
  • the machine 1 includes a control section 10 (shown in Figure 2 ) provided with control means 11, 12 suitable for performing at least measurements of the geometric type (or “linear measurement”), as well as flatness measurements on flat articles 2.
  • control section 10 shown in Figure 2
  • control means 11, 12 suitable for performing at least measurements of the geometric type (or “linear measurement"), as well as flatness measurements on flat articles 2.
  • control means 11, 12 is of the type suitable to perform also aesthetic checkings on the articles 2 tested.
  • the machine 1 comprises conveyor means 3, 4, 5, 6 for continuously conveying the tiles 2 to be tested towards the above-mentioned control section 10, and thereafter toward the output of the machine 1.
  • the conveyor means comprises a conveyor belt 3 suitable to support and move the tiles 2.
  • the proposed machine 1 comprises a belt 3 which defines a continuous conveyor belt, whereon the tiles 2 to be tested are laid, one after the other.
  • the belt of the invention is thus capable of conveying the tiles in an advancement direction D, parallel to the axis of the longitudinal development of the machine itself.
  • the invention preferably comprises a single conveyor belt 3 which is able to convey alone the tiles 3.
  • the width of the belt 3 defines the maximum transverse dimensions of the conveyor means, possibly not including the input and output ends of the machine 1; this aspect shall be better detailed in a later section.
  • a cab 13 is mounted at the control section 10, in which cab 13 there is located the control means 11, 12 mentioned above.
  • control means preferably includes optical devices (such as cameras 11 and laser projectors 12), pointing in the direction of the belt 3, i.e., towards the horizontal plane 31 on which the tiles 2 are passing one after the other.
  • optical devices such as cameras 11 and laser projectors 12
  • the control means may further include a processing unit for managing the optical devices 11, 12 and processing the acquired images in order to perform control and provide the results of performed calculations to the operator.
  • the belt 3 defines a kind of movable "floor" of the cabin 13.
  • the conveyor means comprises two opposite pulley means 4, 5, respectively arranged at the input I and the output U of the machine 1.
  • Such pulley means may be constituted e.g. by rollers 4, 5 or similar rotatable elements.
  • the belt 3 of the invention is closed in a loop around the two pulley means 4, 5 already mentioned, thereby defining two parallel and horizontal planes 31, 32.
  • the horizontal movable conveyor belt whereon the tiles 3 are restingly lying, is constituted by the upper surface 31 of the belt 3.
  • This upper surface 31 is crossing aforesaid control section 10, by entering and exiting the cab 13 through appropriate openings.
  • the conveyor means comprises two guide rollers 4, 5 in all, rotatable about the axes which are parallel to one another and horizontal, which guide rollers 4, 5 are placed in opposite positions along the longitudinal development of the machine 1.
  • One of these rollers 4, for example the one arranged at the output U, is set in rotation by a suitable motor 6, while the other roller 5 is preferably idler.
  • the invention may provide use of a backlight 14 arranged in the control section 10, below the upper surface 31 of the belt.
  • the width of the belt 3 is equal to or greater than the maximum width of the tiles 2 to be inspected.
  • the width of the conveyor belt 3 defines the maximum transverse dimensions of the conveyor means, at least in the portion comprised between the two pulley means 4, 5.
  • the conveyor belt 3 of the machine 1 which extends to the whole width with respect to the conveying zone, supports the tiles 2 by coming in contact with the entire bottom surface, or in any case a preponderant portion thereof.
  • the tile 3 is resting on a continuous horizontal plane 31, which completely prevents or greatly limits the effects of gravity on the flatness of the tiles 2 conveyed, i.e., that kind of bending effect which, tends to distort flatness measurements in the prior art.
  • the invention is able to perform reliable flatness measurements even in relation to long and slim tiles referred to above.
  • the tiles 2 may translate without being subjected to any rotations which in the prior art are due to imperfect parallelism of the belts.
  • the machine 1 of the invention of course includes a support base 7 consisting of a pallet or the like and may include additional devices and components the control machines are usually provided with.
