Definitions

  • the present invention relates to an automatic system for manufacturing standard and special bricks, floor tiles, plain roofing tiles and other tiling of any shape.
  • Some of these systems comprise a conveyor chain to which a plurality of molds are applied; said molds are conveyed below a clay feeding hopper to simultaneously fill one or more side-by-side molds.
  • these systems provide for a preset position of the clay feeding hopper with respect to the molds which entails inevitable friction and wear due to the mutual sliding of the mold and the outlet of the hopper.
  • the aim of the present invention is to eliminate the above drawbacks of conventional systems, providing an automatic system for manufacturing standard and special bricks, floor tiles, plain roofing tiles and other tiling components of any shape which allows to perfectly dose the clay during mold filling, to eliminate additional pressing, skimming and dosage operations, to adjust the mold filling pressure and to reduce friction and wear between the mold and the clay outlet.
  • the system according to the invention further allows high operating flexibility and increases productivity, reducing both downtimes and tooling costs.
  • an object of the present invention is to achieve the above aim with a structure which is simple, relatively easy to provide in practice, safe to use, effective in operation, and has a relatively low cost.
  • an automatic system for manufacturing standard and special bricks, floor tiles, plain roofing tiles and other tiling components of any shape characterized in that it comprises: a moist clay mixer; a part forming machine; a station for supporting a mold holder provided with means for fixing at least one mold, said station being arranged below said forming machine; a unit for the wire cutting of the formed parts; and a transfer line for said mold holder.
  • the reference numeral 1 generally designates an automatic system or apparatus for manufacturing standard and special bricks, floor tiles, plain roofing tiles and other tiling components of any shape, according to the invention.
  • the system 1 is constituted by a moist clay mixer 2, a part forming machine 3, a station 4 for supporting a mold holder 5 located below the machine 3, a unit 6 for wire-cutting the formed parts and a line 7 for transferring the mold holder 5.
  • FIGS 2 and 3 are views of a mixer 2 of the rotary type, which comprises a tank 8 which has a vertical axis to which the clay is sent, through a feeder conveyor 9, after being already mixed and moistened by other devices arranged upstream.
  • the tank 8 is cylindrical and is internally provided with a central rotating shaft 10 which has radially arranged blades and skimming elements 11 that provide distinct functions for mixing, moving the moist clay radially as well, and for removal from the walls of the tank 8.
  • the forming machine 3 has a clay filling and pressing chamber 12 which is arranged below the tank 8 of the mixer 2 and is connected thereto through an inlet 13, through which the overlying clay is conveyed.
  • the chamber 12 has a first tubular portion 14 at which the inlet 13 is tangent to the chamber 12; a guillotine 15 can be interposed which is associated with actuation means 16 adapted to move it from a configuration in which the inlet 13 is open to one in which said inlet is closed.
  • the machine 3 comprises a piston 17 which is installed so that it can move longitudinally in the portion 14 of the chamber 12 and is associated with a fluid-actuated jack 18 whose actuation in one direction, with the guillotine 15 in the closing configuration, is adapted to propel the clay inside the chamber 12 towards an opening 19 for loading the clay into a mold 20 of the underlying mold holder 5.
  • the guillotine 15 is closed so as to prevent the clay from flowing back towards the tank 8.
  • the propelling action is performed by the piston 17, which moves forward all of the continuous mass of clay until the mold 20 is filled.
  • the actuation of the jack in the opposite direction, with the guillotine 15 in the open configuration, is instead adapted to suck the clay from the tank 8.
  • the chamber 12 is provided with a first cylinder 21 which has a vertical axis and inside which the excess clay is accumulated simultaneously with the filling of the underlying mold 20.
  • the cylinder 21 contains a hermetic secondary piston 22 which, by means of a stem 23, is rigidly connected to a second cylinder 24 of the pneumatic or fluid-actuated type.
  • An adjustable pressure is set in the upper chamber of the second cylinder 24 and, by means of the secondary piston 22, produces a counterpressure which determines the actual pressing pressure of the clay inside the mold 20.
  • the supporting station 4 is arranged below the filling opening 19 of the chamber 12 and has elements 25 for quickly lifting and lowering the mold holder 5 in two steps.
  • the elements 25 comprise a grid 26 adapted to lift the mold holder 5 from the transfer level and to position the mold 20 so that it adheres to the filling opening 19.
  • the filling opening 19 is provided with closure means 27 of the fluid-actuated type which are controlled so as to facilitate maintenance or replacement of said opening.
  • the dimensions of the opening 19 are chosen so that it couples hermetically to the mold 20 to be filled, so as to allow the pressurized clay to pass from the chamber 12 to the mold 20 without any outward loss of excess clay.
  • the cutting unit 6 is constituted by a wire 28 which is supported and stretched between two lateral supports, not shown in the various figures, which are associated with movement means adapted to pass the wire 28 between the filling opening 19 and the mold 20.
  • the mold holder 5 which accommodates the mold 20 to be filled, is moved below the opening 19 by a device of the quick-moving vocational-progress type or by a transfer chain (for smaller productions); once in position, it is lifted by the moving grid 26 until it adheres to the filling opening 19.
  • the moving grid 26 descends to a cutting level which lies directly below the filling level, depositing the mold holder 5 on the quick-moving device so as to space the mold 20 slightly from the opening 19 and allow the wire 28 to separate the flow of clay that fills the mold 20 from the rest of the flow inside the chamber 12.
  • the mold holder 5 is lowered to the transfer level and then moved forward so as to make the mold 20 exit from the forming machine 3 without causing any friction and/or wear between the opening 19 and said mold and between the component and the clay remaining in the opening.
  • the mold holder 5 advances along the transfer line 7, on which the following elements are installed in succession: a station 29 for placing the mold holders mutually adjacent; a station 30 for resting an inverted platform on the mutually adjacent mold holders; a station 31 for overturning the mold holders together with the associated platform; a station 32 for emptying the molds; a cleaning station 33; a sanding station 34; and a mold holder overturning station 35.
  • the mold holder 5 is arranged laterally adjacent to the mold holders that precede it or follow it, so as to form a compact group 36 whose length approximately corresponds to the length of a platform 37 superimposed thereon in the subsequent resting station 30.
  • the mold holders are arranged mutually side by side automatically, and the platforms 37 are placed on the respective groups 36 through automatic-movement means such as a mechanical arm 38 which removes the platform from a conveyor line 39 or, as an alternative, from a previously accumulated stack.
  • the subsequent station 32 for emptying the molds 20 is constituted by a clamp which, by means of a pick-and-place device 42 with double lateral grip, removes the mold holders 5 and, with a lifting movement accompanied by a vertical-type vibration, empties the molds 20, releasing the components onto the platform 37, and sends the mold holders 5 along the transfer line 7.
  • the components extracted from the molds 20 and placed on the platforms 37 are sent, with conventional devices, to the subsequent processing steps.
  • the mold holders 5, with the corresponding molds 20, are cleaned in a sort of tank 43 with jets of pressurized water that arrive from a plurality of finely perforated ducts arranged in a downward region or as in the solution of Figure 7, in which the molds are cleaned while they move by means of movable and/or fixed nozzles.
  • a station 44 is provided for partially drying the cleaned mold holders by aspirating the larger water droplets.
  • the sanding station 34 is located downstream of the cleaning station and comprises a centrifugal vane sandblasting machine with an adjustable supply of sand, powder, wood sawdust or other materials.
  • the mold holders 5 are rotated through 180 degrees so that the molds 20 are directed upwards again.
  • Figures 4, 5 and 6 illustrate a mold holder 5 according to the invention.
  • the dimensions of the mold holder are chosen according to the maximum dimension of the filling opening 19 or in any case according to the dimensions of the parts to be manufactured, and the mold holder is provided with means 46 for fixing at least one mold 20.
  • the mold holder comprises a container 47 which is shaped like a parallelepiped and constitutes a casing in which the molds 20 are inserted regardless of their size: molds having different dimensions and shapes can also be installed in a same mold holder.
  • Two lateral wings 48 are located laterally to the container 47 and are used as sliding surfaces for the mold holder along the transfer line 7 so that although the dimensions and the thickness of the installed molds vary, the sliding surfaces remain unchanged and require no additional adjustment.
  • each mold holder 5 the mold can be replaced easily by simply removing the fixing means 46, constituted for example by eight conventional bolts.
