Definitions

  • the present invention relates to an improved apparatus for producing tiles or other articles from cementitious mixes.
  • Apparatus for preparing and shaping cementitious mixes to form tiles or other articles of different shapes and thicknesses have been known for some time and have been the subject of very many patents such as French Patent 2117398, Italian Patents 1023789 and 1786883 and European Patent Application EP-A-0893219.
  • the known apparatus comprise a mould for receiving a metered mass of cementitious mix and a punch for compressing this mix into the mould.
  • the mould comprises a rigid frame and a grid presenting a large number of holes with their diameter gradually increasing downwards and communicating with drainage channels for the liquid which passes through said holes when each tile is formed.
  • the rigid frame is rested on said grid and defines with it a cavity (open upwards) into which metered quantities of cementitious mix are fed to form individual tiles.
  • a punch operable by a press and movable between a position in which it is raised away from said rigid frame and, respectively, a position in which the free end of the punch penetrates into the aperture in the rigid frame to compress the cementitious mix present in it.
  • the main object of the present invention is therefore to provide an apparatus for producing tiles from cementitious mixes, in which the liquid which seeps between the mould and punch during compression of the mixes is withdrawn and removed effectively from the apparatus.
  • Another object is to form the apparatus in such a manner that the withdrawal and removal of the liquid take place via conduits or channels which can be easily inspected and cleaned to prevent them becoming blocked.
  • an apparatus comprising a mould and a punch movable relative to the mould, in which the mould comprises both a base grid superposed on drainage channels and a frame superposed on said grid and defining therewith a cavity for housing and retaining a mass of cementitious mix, the punch having one end at least partially insertable into the frame cavity to compress said cementitious mix into the mould and form a tile, characterised in that in that region of the mould into which said end of the punch is insertable there are provided members for drawing away the liquid which seeps between the punch and the mould during the pressing of the cementitious mix.
  • said members comprise a plurality of channels, of which one end opens at that edge of the mould frame facing said cavity and the other end is connected to a vacuum or suction pump.
  • said channels are formed in an annular rigid body which is superposed on said frame and is connected to mechanical members arranged to raise said body away from the frame and respectively to rest it and to press it thereon.
  • said annular rigid body is formed by connecting together several rigid body parts in a manner mutually separable to enable the channels provided within them to be cleaned.
  • the apparatus for producing tiles shown in the figures comprises a mould and a pressing punch which are superposed and movable one relative to the other.
  • the mould in its turn comprises a rigid base plate 1 in which there are provided a plurality of drainage channels 2 having their bottom inclined to cause the liquids collected in them to flow towards discharge pipes 3.
  • a base grid 4 formed from one or more plates presenting a plurality of holes (shown only in the left side of the figures, in section) on which there rests a mesh or cloth 5.
  • a pressing punch 9 connected to a movable piston 10 of a press.
  • the shape and size of the lower (with reference to the drawing) part of the punch 9 is such that it can penetrate (with the smallest possible clearance) into the cavity of the frame 6 to compress the mass of cementitious mix 8, as shown in Figure 2.
  • the main object of the apparatus of the present invention is precisely to eliminate the aforesaid drawback.
  • a rigid ring 13 the lower surface of which is shaped such that the ring 13 defines with the upper surface of the frame 6 (when the ring rests on the frame, as shown in Figure 2) an annular chamber 14 open towards the lateral surface of the punch 9 and connected via conduits 15 to a suction pump or the like (not shown) which draws away all the liquid which can seek between the punch and the mould frame.
  • the ring 13 is secured to the punch 9 by springs 16 or the like which enable the ring to translate axially relative to the punch.
  • Air suction through the conduits 15 and the chamber 14 commences as soon as the punch 9 begins to penetrate into the mould, and ceases on termination of the pressing operation, when the punch is raised away from the mould ( Figure 1).
  • the ring 13 is formed from two or more rings or ring segments connected together in a manner which enables them to be easily and quickly separated, to allow easy access to all the conduits provided in the ring and hence simplify to a maximum the cleaning of the conduits to remove any deposits or incrustations formed in them.
