Definitions

  • the present invention relates to a tile production press and a device for charging powder into the mold which allows achievement of a diversified surface layer to obtain tiles with special surface effects.
  • the general purpose of the present invention is to remedy the above mentioned shortcomings by making available a press and charging system with distribution of surface layers of powder allowing achievement of special surface effects.
  • a press with a device for charging a mold therein comprising a conveyor box moving between a reception position for powder therein and a position for dumping the powder into the mold characterized in that the charging device comprises a hopper moving with the box to transit above the mold during movement of the box and commandable for release into the mold of additional powders loaded therein.
  • FIG 1 shows a press 12 equipped with a charging device indicated as a whole by reference number 10 for a mold 11 of the press.
  • the charging device comprises a powered unit or carriage 13 which translates between a charging position (FIG 1) and a dumping position (FIG 2).
  • the powered unit comprises in turn a conveyance box or grating 14 which upon movement of the unit 13 shifts between a position for reception of powder and a position for dumping of the powder into the mold.
  • the box receives the powder from a hopper 15 located in the reception position and equipped with controlled dumping means 16.
  • the charging system comprises an auxiliary hopper 17 moving with the box 14 to transit above the mold 11 during movement of the box and equipped with dumping means 18 to be commanded to release into the mold 11 additional powder charged into the auxiliary hopper 17.
  • the auxiliary hopper is advantageously arranged in front of the box in the direction of movement towards the mold. This hopper has a front imprint such as to be introducible between the plates of the open press.
  • the feeding means 19 comprise a conveyor 20 which receives powder from ducts 21 and sends it through a flexible duct 22 to a delivery mouth 23 equipped with a controlled cutoff valve 24.
  • the feeding unit making up the means 19 moves along guides 25 in a direction transversal to that of movement of the charging unit 13 and therefore in a direction at right angles to the plane of the drawing shown in FIG 1 so as to run along the entire extension of the hopper 17. If necessary the powder fed can be of a different color for different positions along the hopper 17 so as to achieve differently colored surface effects.
  • the delivery mouth 23 is movable vertically by means of an actuator 26 so it can be lowered into the hopper during feeding as shown in FIG 1 and then withdrawn as seen in FIG 2 to allow movement of the charging unit 13.
  • the auxiliary hopper 17 can be equipped with mixing paddles moving longitudinally and alternately with respect to the main axis of the hopper through an actuator 28.
  • the paddles can have different configurations. Air vibrators can also be applied.
  • the auxiliary hopper 17 can have on its outlet a dumping grating 29 and the dump valve 18 can be shaped as desired to dump the contents of the hopper in a predetermined manner.
  • a roller 30 operated by an actuator 31.
  • roller 30b In addition to or in replacement of the roller 30 there can be between the auxiliary hopper and the box a roller 30b with its own actuator 31b.
  • the roller 30b and if desired the roller 30 are equipped with peripheral projections 31.
  • the charging device In use the charging device is initially in the position of FIG 1. In this position the feeder 19 runs along the auxiliary hopper dumping the additive powder therein.
  • the dispenser 23 After charging, the dispenser 23 is raised and the carriage 13 begins the run towards the dumping position.
  • the main upper hopper 15 charges the box or grating 14 in accordance with the prior art.
  • any mold cleaning means can be activated.
  • These means can be made e.g. with movable rotating brushes 33 located between the box and the auxiliary hopper.
  • auxiliary hopper 17 which had advanced together with the box returns above the mold and is operated to dump its contents over the material already charged into the mold so as to form a different surface layer.
  • the front roller 30 During return travel it is possible to operate the front roller 30 to achieve compression of the powder and better compactness. If desired, simultaneously or alternating with the roller 30 the roller 30b if any can produce incisions 32 in the powder before it is reached by the auxiliary hopper so that the auxiliary hopper will dump into the grooves produced. In this manner original aesthetic effects can be achieved.
  • the valve 18 of the auxiliary hopper can be a slide valve.
