A device for loading a dosage layer of material, preferably concrete, at a laying-down position for manufacturing tiles and the like comprising, a conveyor for supplying a continuous layer of the material, a bell having a diaphragm and edges surrounding the diaphragm defining a dosage space for receiving a dosage layer of the material and a driving unit for driving the bell to move it into engagement with the continuous layer on the conveyor to receive a dosage layer of material in the dosage space. A suction pump is connected to the interior of the bell for establishing an underpressure therein so that the dosage layer of material is held by suction in the dosage space. A plurality of the bells may be provided on a single turret so that one dosage layer of material is being drawn up while another dosage layer of material is being laid down at another location.
A device for loading a dosage layer of material at a laying-down position to form a tile comprising, material layer supply means adapted for providing a layer of material in a drawing-up position, bell means having an air-permeable diaphragm and a surrounding edge defining a dosage space for receiving the dosage layer of material, drive means connected to said bell means for intermittently moving said bell means into the drawing-up position to receive a dosage layer of material in said dosage space and then into the laying-down position to release the dosage layer of material, and suction means connected to said bell means for establishing an under pressure in said bell means when said bell means is at the drawing-up position for holding the dosage layer in the dosage space and for establishing atmospheric pressure in said bell means when said bell means is in the laying-down position for releasing the dosage layer of material, said drive means comprising rotary drive means for rotating said bell means angularly from the vicinity of the drawing-up position to the vicinity of the laying-down position, vertical drive means for moving said bell means vertically down into the provided layer of material in the drawing-up position and down into the laying-down position and a column, said bell means comprises a turret carrying a plurality of bells each having a diaphragm and surrounding edge, said turret rotatably and slidably mounted on said column, said rotary drive means comprising a fixed arm connected to and extending radially outwardly of said column, a rotatable arm rotatably mounted to said column, an actuator connected between said fixed and rotatable arms for rotating said rotatable arm, and an engagement pin connected to said rotatable arm and movable by said vertical drive means to engage said turret and rotate said turret.
A device for loading a dosage layer of material at a laying-down position to form a tile comprising, material layer supply means adapted for providing a layer of material in a drawing-up position, bell means having an air-permeable diaphragm and a surrounding edge defining a dosage space for receiving the dosage layer of material, drive means connected to said bell means for intermittently moving said bell means into the drawing-up position to receive a dosage layer of material in said dosage space and then into the laying-down position to release the dosage layer of material, and suction means connected to said bell means for establishing an underpressure in said bell means when said bell means is at the drawing-up position for holding the dosage layer in the dosage space and for establishing atmospheric pressure in said bell means when said bell means is in the laying-down position for releasing the dosage layer of material, said drive means comprising rotary drive means for rotating said bell means angularly from the vicinity of the drawing-up position to the vicinity of the laying-down position, vertical drive means for moving said bell means vertically down into the provided layer of material in the drawing-up position and down into the laying-down position said suction means comprising a shutter having at least one aperture therethrough, a column for rotatably and slidably supporting said bell means and for rotatably receiving said shutter, a suction pump connectable to an interior of said bell means, said shutter rotatable to establish communication between the interior of said bell means and said pump and for blocking such communication.
