Definitions

  • the present invention relates to a machine for colouring ceramic products.
  • a machine for colouring ceramic products with a powdered colouring substance comprising an operating station and a metering unit for dispensing said powdered substance; characterized in that said unit comprises at least one dispensing member presenting a rotary dispensing body, and at least one hopper for housing said substance and communicating with said dispensing body; said dispensing body comprising a number of nozzles for receiving said substance from said hopper; and said unit also comprising an actuating device for moving said dispensing member in relation to said product at said operating station, so that a nozzle containing said substance is positioned facing a respective said given portion of each said face at said station.
  • Number 1 in Figure 1 indicates a machine for colouring ceramic products, e.g. tiles 2 presenting a substantially flat upper face 3 for colouring in various ways.
  • faces 3 may conveniently be divided ideally into a given, e.g. grid, pattern defining given portions.
  • Machine 1 comprises an operating station 5 at the output of machine 1; a metering unit 6 for gravity feeding given quantities of powdered dye 7 at station 5; and a conveyor 8, the horizontal conveying branch of which extends in a given substantially horizontal direction 9 (Figure 2) to feed tiles 2 through station 5 and beneath unit 6 for colouring.
  • unit 6 comprises two dispensing members 10 and 12 substantially aligned with each other in a substantially horizontal direction 13 perpendicular to direction 9, and connected rigidly to each other by a connecting member 16 shown schematically in Figure 1 and which ensures members 10 and 12 are maintained equidistant at all times.
  • Unit 6 also comprises an actuating device 19 for moving and supporting members 10 and 12, and which presents a step- or continuously-operated linear actuator 20 (shown schematically in Figure 1) for moving members 10 and 12 through station 5 in direction 13 and to and from an idle position in which members 10 and 12 are located downstream from station 5, in the traveling direction from member 10 towards station 5 in Figure 1, and astride station 5 as shown in Figure 2.
  • Device 19 also comprises a pair of step- or continuously-operated linear actuators 21 (shown schematically in Figure 1) for selectively moving members 10 and 12 to and from the idle position through station 5 in direction 9.
  • device 19 therefore provides for moving members 10 and 12 within a substantially rectangular work area defined by opposite sides parallel to directions 9 and 13.
  • Unit 6 also comprises an electronic central control unit 22; a pneumatic device 24 for producing high-pressure gas, normally air; and a further pneumatic device 26 for generating a vacuum.
  • central control unit 22 and devices 24 and 26 are shown schematically in block form, and the operation of each is described in detail later on.
  • Member 10 extends along an axis 14 parallel to direction 9, and comprises at least one substantially prismatic hopper 28 (two in the example shown, as illustrated in Figure 2) presenting a downward-facing opening 30.
  • Beneath hopper 28, member 10 comprises a ring 32 coaxial with axis 14, freely rotatable and axially fixed in relation to axis 14, and presenting a number of radial through openings or nozzles 34 equally spaced about axis 14, and each of which sweeps past bottom opening 30 of hopper 28 at each turn of ring 32, and is connected in airtight manner to device 26 so that, when device 26 is activated, a vacuum is substantially maintained in nozzles 34.
  • conveyor 8 must be so adjusted in height that faces 3 of tiles 2 on the conveying branch of the conveyor are positioned immediately below nozzles 34.
  • Nozzles 34 commence drawing off dye 7 when devices 24 and 26 are activated and dispensing body 39 is rotated clockwise (in Figure 1) by device 19 via a respective rotary actuator 50 (shown schematically in the drawings). It should be pointed out that dye 7 is fed into each nozzle 34 by force of gravity combined with the vacuum generated by device 26; that the dye 7 inside nozzles 34 downstream from respective openings 30 is retained inside nozzles 34 by the suction generated by device 26, and does not escape even when nozzles 34 are located beneath axis 14, 15; and, finally, that, in any case, the inside of dispenser 36 is protected by body 42, which retains dye 7 on the outside of ring 38.
  • central control unit 22 opens the corresponding valve 46 for a given length of time to dispense a given quantity of dye 7.
  • lines of given shape may be drawn on face 3 of tile 2.
  • arresting tiles 2 in station 5 is only one of the possible operating modes of machine 1.
  • the colouring of tiles 2 may be speeded up by central control unit 22 so operating device 19 and conveyor 8 as to feed given portions of tiles 2 towards a given nozzle 34 at any rate as required.
  • the number of hoppers 28 may be increased, even to the extent of providing a hopper 28 for each nozzle 34.
  • simplified dispensers 10 and 12 may be provided, each with a single hopper 28.
