Definitions

  • the present invention relates to a unit for decorating ceramic products, and in particular to a unit for decorating ceramic products with powdered or granular decorating material.
  • Document FR-B-1230051 discloses a unit for decorating products with relative patterns, and comprising a decorating device comprising at least one flexible decorating member extending along an endless path and having a number of holes, each pattern being defined by at least one hole.
  • the decorating device further comprises feed means for feeding a decorating material through the holes of the flexible decorating member, first actuating means moving the products in a given first direction, and second actuating means moving the flexible decorating member along its endless path.
  • each product 2 is substantially flat, is substantially rectangular parallelepiped-shaped, and is defined by two substantially parallel major lateral faces 2a.
  • Unit 1 comprises an endless conveyor 4 for feeding a succession of groups 5 of products 2 in a given direction 6 and along a given path P1.
  • Groups 5 are substantially equally spaced along conveyor 4, and each comprise a number of - in the example shown, three - products 2, which are aligned with one another in a direction 7 substantially crosswise to direction 6, and are fed along path P1 "laid flat", i.e. with relative faces 2a horizontal.
  • Conveyor 4 comprises a belt 8 looped about two pulleys 9 - one of which is powered continuously - which are fitted to a fixed frame (not shown) of unit 1 to rotate, with respect to the frame (not shown), about respective axes 10 substantially parallel to each other and perpendicular to the Figure 1 plane.
  • Unit 1 also comprises a decorating device 11 located along path P1 at a decorating station 12, and in turn comprising a flexible decorating member 13, which is moved by an actuating device 14 along an endless path P2, and is located over conveyor 4, at a given distance from products 2 for decorating.
  • a decorating device 11 located along path P1 at a decorating station 12, and in turn comprising a flexible decorating member 13, which is moved by an actuating device 14 along an endless path P2, and is located over conveyor 4, at a given distance from products 2 for decorating.
  • Device 14 comprises two shafts 15 - one of which (hereinafter indicated 15a) is located beneath the other and is powered continuously by an electric motor 16 - which are fitted to said frame (not shown) to rotate, with respect to the frame (not shown), about respective axes 17, which extend substantially parallel to each other and to axes 10, and are substantially aligned with each other in a vertical direction A perpendicular to directions 6 and 7.
  • Each shaft 15 is fitted, at each free end, with a wheel 18 having a number of pins 19, which are equally spaced about relative axis 17, and extend radially outwards from the outer surface of wheel 18 to engage corresponding holes 20 formed along the lateral edges of member 13, and so rotate member 13 about axes 17 and along path P2.
  • Member 13 comprises a number of groups 21 of patterns 3, which are arranged along member 13 with substantially the same spacing as groups 5, and each comprise a respective number of patterns 3 (equal to the number of products 2 in each group 5), each of which is defined by at least one hole 22 formed through member 13, and is advanced in time with a relative product 2.
  • device 11 also comprises a hopper 23 for containing a decorating material (in the example shown, a powdered or granular decorating material), and which extends in direction 7, is located between the two vertical branches of member 13, and in turn comprises a downwardly-converging top portion 24, and a bottom portion 25 defined by a tubular body 26 extending about shaft 15a and coaxial with relative axis 17.
  • a decorating material in the example shown, a powdered or granular decorating material
  • Body 26 has a diameter substantially equal to the diameter of wheels 18, and comprises a top opening 27 formed radially through body 26 so as to face portion 24; and a number of bottom slots 28, which are equal in number to products 2 in each group 5, and therefore to patterns 3 in each group 21, are formed radially through body 26 so as to face member 13, and are each of a width, measured parallel to direction 7, at least equal to the width of a product 2, also measured parallel to direction 7.
  • Hopper 23 also comprises a valve device 29 for selectively controlling supply of said decorating material through slots 28, and therefore through holes 22, and which comprises a shutter member 30 defined by a tubular body 31 extending through body 26 and about shaft 15a, and substantially coaxial with axis 17 of shaft 15a.
  • Body 31 comprises a top opening 32 formed radially through body 31 and facing opening 27; and a number of bottom slots 33, which are equal in number to slots 28, are formed radially through body 31, and are each of a width, measured parallel to direction 7, at least equal to the width of a slot 28.
  • Body 31 is fitted in rotary and axially fixed manner to both body 26 and shaft 15a, and is oscillated - with respect to body 26 and shaft 15a, and by an actuating device 34 - about relative axis 17 and between an open position opening slots 28 (Figure 3) and a closed position closing slots 28 ( Figure 4).
  • Device 34 comprises two actuating cylinders 35, which are located on opposite sides of body 26 in direction 7 and inside the two vertical branches of member 13, are hinged to said frame (not shown) of unit 1, and have respective output rods 36, the free ends of which are hinged to respective levers 37 extending outwards from the outer surface of body 31.
  • conveyor 4 and decorating member 13 are operated continuously to feed each product 2 through decorating station 12 in time with a relative pattern 3; and shutter member 30 is moved into the open position as patterns 3 travel past slots 28, to allow the decorating material to drop down on to products 2, and is moved into the closed position as the portions of member 13 with no patterns 3 travel past slots 28.
  • unit 1 As such, unit 1:
