Definitions

  • the present invention relates to a press for tile pressing molds having an innovative charging device and in particular for producing colored streaks or veins in the mass.
  • a widely used system comprises a box with dimensions similar to the cavity in the mold to be filled.
  • the box is open at the bottom, has rods for entrainment of the powders to be pressed and runs on a plane from a charging position outside the mold to a dumping position vertically above the mold.
  • the mold has the bottom of the cavity formed by the movable lower plug. When the plug is in the upper position it is level with the running plane of the box so that the box remains closed below, first running on the plane and then running on the plug. Once the full box arrives above the plug the plug is lowered to form the cavity and cause dumping of the powder from the box into the cavity.
  • the charging device comprises a vertical accumulation well into which powder is appropriately fed for producing the mass of the tile and powder for production of the streaks in the mass.
  • the accumulation well dumps from below into the box arranged beneath it during a traversing movement of the box in relation to the accumulation well. The box thus filled is moved over the mold to dump the powder into the mold.
  • the general purpose of the present invention is to make available an improved device for charging a pressing mold in the press and in particular for production of tiles with different colors in the mass.
  • a tile pressing press comprising a pressing mold into which a charging device dumps powder to be pressed with the charging device comprising a charging box having a bottom opening on command and running between a charging position outside the press and a position for dumping into the mold with the press with the box in its charging position being near means of input therein of powders to be pressed and in its dumping position the box bottom being operated to open and dump the powder into the mold.
  • the charging device comprises a main hopper 15 into which is fed the powder for producing the tile mass and at least one secondary hopper 16 into which is fed powder for producing the streaks or veins in the mass.
  • the main hopper and the secondary hopper receive powders from feed units and ducts 23, 24 respectively.
  • the main hopper 15 and the secondary hopper 16 dump on command (e.g. by means of powered drop gates 25, 26) on a chute 17 for starting the powder toward the underlying box.
  • the main hopper 15 and the secondary hopper 16 traverse transversely along the chute 17 by means of a powered carriage 27 running on guides 28 to distribute the powder dumped on the chute.
  • the dumping from the hoppers takes place in different quantities and at different intervals depending on the specific aesthetic effect it is desired to obtain.
  • an intermediate accumulation well 19 extending vertically and having a lower mouth opened on command by means of an actuator 22.
  • the well 19 receives the powder dumped from the chute above and dumps it on command below into the box arranged beneath it during the movement of the box from its rest position to its position of dumping into the mold.
  • the accumulation well 19 is generally in parallelepiped form with its dimension A in the direction of movement of the box virtually near the internal height of the box and transversal width virtually near the transversal internal width of the box. In this manner the accumulation well once filled dumps the exact quantity of powders necessary for correct filling of the box 18.
  • FIG 2 shows in greater detail the structure of the box 18.
  • the box comprises an outer peripheral frame or rim 36 which defines the vertical walls of the parallelepiped.
  • Opposing side walls support a plurality of rectangular thin plates 37 supported in a rotating manner along parallel axes 38.
  • the thin plates 37 are sized to be superimposed slightly when in horizontal position so as to provide a closed bottom for the box.
  • the pivot axis 38 of each thin plate is virtually coincident with one edge of the thin plate.
  • the frame 36 supports an internal rim 39, 40 to prevent the powder deposited in the box from leaking to the side beyond the thin plates when the latter are in closed position.
  • each thin plate has one of the supporting pins 41 fitted with a crank 42 engaging in a pin 43 protruding from an operating bar 44 supported by supports 45, 46 to run parallel to the side of the external frame 36 upon command of a rod 47 moved by an actuator 48 supported by the carriage 35.
  • the movement can be secured in another manner e.g. with a known rack and pinion system.
  • the box bottom can be opened in the manner of a Venetian blind with all the thin plates 37 rotating synchronously downward to move into an inclined position (advantageously vertical as shown in FIG 4) when the actuator 48 is operated to move the operating bar leftward as shown in the figures.
  • powder charging takes place first with charging into the vertical well 19 of appropriate powders coming from the hoppers. Once the well is charged the gate beneath it is opened by operating the actuator 22 to dump along the horizontal box 18 (with bottom Venetian blind) which simultaneously traverses under the well to move into the position of dumping into the mold. The box is thus filled with distribution prearranged in the vertical well during charging.
  • the box After charging, the box terminates its travel to the dumping position.
  • the actuator 48 When the box is in position for dumping into the press the actuator 48 is operated to open the Venetian blind bottom and dump the powders into the mold below.
  • the carriage 35 can then return to its starting position as shown in FIG 1 and the press can be operated for tile pressing.
  • the cycle can then start over from the beginning.
  • a shaped metal sheet 51 (FIG 3) through which the powder falls can be provided to improve its distribution and prevent forming of aesthetically unacceptable streaks.
  • FIG 5 shows an alternative embodiment of a device in accordance with the present invention.
  • members similar to those of the embodiment of FIG 1 are designated by the same numbers multiplied by one hundred.
  • a press with mold 111 between the press plates 112, 113 and a box charging device 114 comprising a charging box 118 mounted on a powered carriage 135 to run between a charging position outside the press plates and a position for dumping into the mold.
  • the charging device comprises hoppers 115, 116 mounted on a carriage 27 running on guides 128 and receiving the respective powders from feed units and ducts 123, 124 and dumping them on command onto a chute 117 for starting the powders toward an accumulation well 119 which extends vertically and has a lower mouth which can be opened on command by means of an actuator 122.
  • the well 119 receives the powder dumped from above by the chute and distributes it into the box during movement of the box from its rest position to its position of dumping into the mold.
  • the box 118 is closed below by a gate 137 connected by a connection 147 to an actuator 148.
  • the lower gate In use the lower gate is initially closed as shown in FIG 5. During the charging movement the box receives the powders from the well 119 and moves above the mold to the position shown in broken lines in FIG 5. At this point the lower gate opens to perform the dumping into the mold. In this manner the dumping takes place with the box stopped vertically over the mold. This prevents the remixing of the prior art.
  • the charging device could be multiple to serve pressing molds with multiple imprints as readily imaginable to those skilled in the art.
  • the chargers could be two on opposite sides of the mold so as to allow alternating operation of charging and dumping and thus reduce cycle times.
  • the movement between box and charging well is to be understood as reciprocal movement of one member relative to the other.
  • the charging well 19 be powered to run in the direction opposite that of the movement of the box toward the mold.
