Definitions

  • the invention relates to a photo-electrostatic method and machinery for applying decorative glaze to ceramic tiles, and to the end-product turned out by adoption of such a method -that is, a new method, partly inspired by the Xerox photocopy principle, which will enable printing of a decorative glaze onto ceramic tiles by utilising the appropriate machinery.
  • the prior art in this field consists of a variety of tile glaze-decorating methods and relative devices which provide for projection of the glaze-medium in liquid state through stencils onto the surface requiring decoration; said projection being brought about either centrifugally by disc, or by free-fall, or by spray-gunning, or with a system of revolving delivery-receptacles, or by silkscreen process - this with either a flat screen, or a set of screens fitted to a revolving drum.
  • Al such techniques are characterised by the use of glaze in liquid state.
  • the invention described herein solves said problem through the adoption of a decorating-method which is to some extent inspired by xeroprinting, the application of xerography to photocopy reproduction developed by the Xerox company.
  • the Xerox method makes provision for build-up of a positive charge in a selenium-coated conductor to some 6000 volts (this by inducing a 'corona' phenomenon) in order to render it light-sensitive. Light reflected by the white areas of the image to be reproduced will then hit the selenium correspondingly, so as to allow selective earthing-out of the positive charge, leaving behind a positively-charged area which will correspond to the image's dark parts.
  • the conductor-image is then capable of attracting a special black powder which is negatively charged and consists of a carrier-medium (graphite, usually) and a thermoplastic resin pigment, this being strewn onto the blank copy-paper and fixed by heat-treatment, so as to obtain a permanent reproduction,
  • An improved embodiment of the machine set forth as per the invention described herein envisages positioning of the transparency within a revolving glass cylinder which is caused to turn synchronously both with the image-transfer cylirder, and with the ongoing movement of the tile beneath, whilst the tile's position with respect to the image-transfer cylinder is adjustable, such synchronous movement provided for by a drive- and transmission associating all the machine's rotating parts one with the other,
  • Advantages offered by the invention are these: a simplified glazing-procedure; elimination of glaze in the liquid state, and attendant problems; a more compact glaze-decoraticn plant; less maintenance; little or no waste/rejects; quick set-up for the single product scheduled; no large vacuum and cleaning installations; no glaze-encrusted equipment to clean and wash down; reduction in manpower and running-costs; a more faithful reproduction of the projected image; and finally, a cleaner and more clear-cut reproduction, perfectly centred on the decorated surface of the tile.
  • 1 denotes a pair of belts carrying the single tiles 2 forward onto a cog-belt denoted 3 which propels them further forward onto guides 4 at the bottom side of the cylinders, these lying above said cog-belt 3, and between further lateral guides 5; 6 denoting the teeth fixed to belt 3 which drag each single tile along through the machine, as well as carrying a synchroniser block 7 for timing purposes, 8 denotes a pair of guides made fast to the upper part 9cF the machine framework, this in turn associated with the base 10 by way of uprights 11, said guides 8 accommodating the slide of a carriage 12 which reciprocates the transparency 13 providing one of the colours to be printed on tile 2, 14 is the vertically-disposed reflector of a lamp 15 mounted to upper-framework 9 which projects a beam of light through transparency 13 by way of the slot 16 located in a baffle denoted 17; ventilation is afforded by a tube 18.
  • 19 denotes a transparent plate fitted to the frame 20 forming part of carriage 12, and providing the mount for said transparency 13, which is held in position by the weight of a further top transparent plate 21 hinged to said frame.
  • 22 denotes a spring anchored at one end to the end of frame 20, and at the other to framework 9.
  • 23 denotes the extremity of a cable fixed to the carriage 12 carrying transparency 13, and sliding within a flexible sheath 24 attached to the entry end of upper framework 9 and bent round and away so as to turn back in toward the machine and connect up with a longitudinal 25 disposed at centre and fixed to two cross-members 26.
  • 31 denotes a horizontal slot in said longitudiral 25 extending the entire length of the latter and accommodating the slide of two bottom cross-pieces 32, 32' associated with the cycle timing-block 7.
  • 33 is an adjustable sleeve fitted to the enry-end of said longitudinal and provided with a raked face 34 designed to draw the first cross-piece 32' offered by block 7 down into a recess 35 located below the level of slot 31 at that end thereof, such that the timing-block 7 itself dips forward and down so as to disengage its own trailing top-end 36 from the tooth 6 which would hitherto have been drawing it along together with tile 2.
  • 37 denotes a transverse slot at the underside of said longitudinal 25 which underlies the first cross-piece 32' when in its drawn-back position, whilst 38 is a stop associating with said slot by virtue of its being fixed to the end of a flexible lath 39 fitted likewise to the underside of longitudinal 25.
  • 40 represents an electromagnet which frees slot 37 whenever it is wished to avoid timing-block 7 beirg carried forward by tooth 6 -in short, when there is no tile 2 to be decorated.
  • 41 denotes the opposite end of the cable aforesaid made fast in like manner to end 23, in this case to the trailing end of the timing-block 7.
  • 42 denotes a transversely-disposed screen of optic fibres located beneath the slot 16 in baffle 17 and arranged in two staggered sets, borne up thus at either side by the two side-walls 43 of a box structure 44 mounted on base 10.
  • a pair of opaque side-members 45 fixed to the upper part of box 44 converge downward toward the optic fibres, and have the function of gathering in those outer rays emanting from lamp 15 whose beam is intended exclusively for the fibres 42 themselves.
  • 46 denotes the basic structure of a cylindrical conductcr designed to transfer the docorative image, whose transversely-set shaft 47 lies in a vertical plane passing through the centre-line of lamp 15 and fibres 42 alike, said shaft journalled at either end to side-walls 43 and thus free to rotate; the outer cylindrical surface 48 of said conductor coated with selenium glass, and the entire component thus embodied -being a conductor- connected to earth.
  • 49 is a tungsten filament, taut and transversely disposed upward and away from cylinder 46-48, and boxed within an enclosure 50 fixed at either end to side-walls 43, this being the means by which a positive charge is imparted to cylindrical surface 48 by the corona effect aforementioned (see fig 6), which raises some 6000 volts between the filament itself and earth.
  • 51 denotes a lamp having a reflector 52 with its throw-aperture 53 directed toward that bend of cylindrical surface 48 exposed to the beam emanating from optic fibres 42, provision being made for a shutter 54 attached to one end of a flexible strip 55 nounted to a support 56 suspended between side-walls 43.
  • 57 is a further elctromagnet designed to attract strip 55 aforesaid in order to open up aperture 53 during the return travel of transparency 13 -this in order that the beam from lamp 51 may cancel out the positive charge induced into surface 48 by filament 49 - said electromagnet being operated by the action of a cam during said return travel.
  • 58 denotes a hopper -likewise a conductor- mounted between side-walls 43 and insulated therefrom, and containing the glaze compound in dry state (denoted 59, and of whatever colour happens to be selected for this machine stage) into which a negative electrostatic charge of a few hundred volts is induced.
  • the hopper incorporetes transversely-disposed rods 60 of prismatic shape, designed to agitate the dry glaze.
  • 61 denotes a further agitator-rod, embodied cylindrically and located at the bottom end of the hopper alongside a further cylinder- the feed cylinder aforementioned - having an insulated body section 62 and a shaft 63 journalled to the sides 64 of the hopper 58 itself.
  • the surface-speed of cylinder 62 is greater than that of cylinder 46-48 by an amount sufficient to compensate for non-conductive interspaces, 65 denotes strips of conductive material (figs 3, 5) disposed about the cylindrical surface area of feeder 62, which makes contact with image-transfer cylinder 46-48 at the bottom entry-side thereof.
  • 66 and 67 denote sectors-to-a-circle of differing length, both conductive, annular in shape, and making-up one common circumference; said sectors fixed to the inside of one of said hopper-walls 64 and disposed thus coaxial with feed-cylinder 62, and furnished with radial conductors 68 directed toward the outer surface of said feed-cylinder Sector 66 is wired to a source of electrical energy supplying some few hundred volts positive charge -preferably of a lower potential than that of hopper 58- whilst sector 67 is wired to a negative source, and positioned nearest the image-transfer cylinder 46-48.
  • 69 denotes the bottom-most point of hopper 58, which is radiused parallel with the cylindrical surface of feeder 62, and has its farthest extremity located within that area where the tow cylinders 62 and 46-48 turn away from one another following contact.
  • 70 denotes a vertical baffle (likewise conductive) fitted to hopper 58 and disposed within a transverse plane dividing feed-cylinder 62, whose lower edge exhibits a bevel, and rides alongside the outer cylindrical surface of feeder 62 at distance such as will allow passage therebetween of a 'dusting' of glaze some few tenths-of-a-millimetre thick.
  • 71 denotes further conductors ranged in alignment below the lower generatrix offered by cylinder 46-48 -that is, at the point of actual I image- transfer onto the tiie; said conductors fashioned from metal, directed toward the cylinder-generatrix, insulated from composite-chassis T aforedescribed, and wired so as to receive a positive eledrical charge. These conductors ride all-but-in-contact with the reverse face of the single tile 2.
  • 74 represents a roller-brush turning around shaft 75 and suspended in rotation between side-walls 43 so as to lie parallel with cylinder 46,48 and act thereon at a point between filament 49 and lamp 72; the bristles of said brush performing a purely mechanical function:that of cleaning off residual glaze 59 from the surface of the image-transfer cylinder, 76 denotes a casing within which brush 74 is enclosed, together with a filter 77 and a fan 78 which provide for the removal of residual glaze.
  • 79 denotes the hinge-pin about which chassis T is caused to pivot, the remaining end of the chassis itself resting upon springs 80, these providing suspension for same.
  • 81 is a gearmotor which drives a shaft 82 journalled to base 10, whilst 83 and 84 are pulleys keyed onto said shaft 82 and further shaft 85, respectively, creating the loop for cog-belt 3 aforementioned.
  • a further pulley 86 likewise keyed to shaft 82 transmits drive by way of a belt 87 to shafts 47 and 75, which drive the image-transfer cylinder 46-48 and roller-brush 74, respectively.
  • a pulley 88 mounted onto return shaft 85 transmits to further shaft 89, this in turn driving a belt 90 whose function is that of turning feed-cylinder shaft 63, cylindrical agitator rod 61 and prismatic rods 60.
  • Bracket-type fixtures 93 associated with uprights 92 and facing inwards afford support, by way of springs 94, to a pair of guides 95 directing the top branches of said belts 91, these being driven by a pair of drive pulleys 96 and returned by further, idle pulleys 97, the drive pulleys being keyed to a shaft 98 journalled at either end to base 10.
  • 99 represents a motorvariator imparting motion to shaft 98 by way of a drive-belt 100.
  • 101 denotes a chain located centrally in the machine at a point between said pair of belts 91, and provided with a detent 102 designed to slow up and position the single tile 2, said chain 101 turning at a lesser speed than that of belts 91.
  • 103 denotes the drive-sprocket for chain 101, and 104 the idle return-sprocket.
  • An electormagne- tically operated stop 105 halts the passage of the tiles upon triggering of a microswitch not shown.
  • 106 denotes uprights issuing from the base 10 of the machine, whose function is that of supporting the box structure 44 within which all the glazing-equipment carried by the machine is housed, 107 denotes a transversely-disposed, hollow glass cylinder having solid ends 108 supported in rotation by trunnions 109, these fitted to respective appendages 110 extending upwards from the side-walls 43 of box 44.
  • a transparency 111 bearing the image for one of the glaze colours to be applied to tile 2 isnounted onto a sector of the inside surface of glass-cylinder 107, whilst -likewise inside the cylinder- a vertically disposed reflector 112 and relative tube lamp 113 are associated with said trunnions 109 at either end.
  • 114 is the baffle defining a slot 115, beneath which one has the two staggered sets of optic fibres 42 aforementioned, suspended between the two side-walls 43 of box-structure 44, as in the first embodiment described.
  • 116 denotes appendages from guides 95 which carry conductors 71 aforedescribed.
  • a pulley 117 keyed onto drive-shaft 98 turns ia cog-belt 118 passing around the following rotary components: the shaft 75 of roller-brush 74, shaft 47 of the image-transfer cylinder 46-48, pulley 119 turning one end 108 of glass-cylinder 107, the uppermost of the two prismatic agitator-rods 60, and further pulley 120 keyed to the sprocket 103 driving chain 101.
  • Pulley120 and drive-sprocket 103 are of size such that the speed of said chain 101 will be less than that of the pair of cog-belts 91 -this in order to enable positioning of the single tiles 2 beneath cylinder 46-48 by means of the detent 102.
  • Pulleys 117 and 119 are of relative diameter such that the surface speed of said glass-cylinder 107 will be equal to the travel-speed of belts 91. Provision is made for a screw-adjusted stretcher 122 acting on belt 118 at a point between pulleys 119 and 120, whilst a further stretcher 123 tensioned by means of a spring is located between pulleys 120 and 117: by working stretcher 122 back or forth at the turn of its screw, pulley 120 can be made to advance or retard with respect to pulley 119 so as to synchronise movement of the transparency 113 with that of the detent 102 offered by chain 101, this bringing about the correct timing between tile 2 and transparency 113.
  • the obtic fibres 42 below project the image line by line onto the top side of transfer-cylinder 46, whose outer surface 48 is already invested with a uniform positive electric charge produced by the 'corona' phenomenon generated by filament 49.
  • the clear areas of the transparency allow passage to the light which, as a result, cancel out the corresponding positively-charged areas on 48 of the cylinder passing beneath.
  • the positively-charged area, or pattern remaining on surface 48 will correspond to the transparency's dark parts, whilst the boundary of the transparency either matches, or is proportioned to, that of the tile 2 itself.
  • Crosspiece 32' forming part of the timing-block 7 now comes up against the recess 35 offered by longitudinal 25 and, thanks to the incline 34 incorporated thereinto, top-end 36 is freed from tooth 6 of the carrier belt 3, and the carriage 12 and timing-block 7 make their respective returns -to-original-position, at the same time triggering electromagnet 57 whose excitation permits light-emission from lamp 51 so as to render the transparency 13 without influence during its return.
  • the dry glaze adheres to the 'dark' parts of surface 48, being positively-charged, though not to those areas already discharged. A remnant will return toward the hopper held by the positively-charged areas of feed-cylinder 62, whilst the particles 59 held by positive charge on surface 48 continue toward the second narrowed area, S', where a tile will be moving forward, in receipt of a positive charge from the conductors 71 beneath.
  • the tiles 2 in the case of a glaze-decoration involving three distinct colours-and mounted the transparencies 111 into their three respective glass-cylinders 107, the tiles 2, already moistened and given their neutral glaze base-coat, can be fed onto the pair of carrier cog-blets 91.
  • the tiles will in fact be appropriately spaced apart by stop 105 via triggering of a microswitch timed with the detent 102 offered by chain 101, such that the detent -travelling at a lesser speed than that of the belts 91 themselves- is enabled to position the single tiles correctly with respect to said glass-cylinder 107; transparency 111 mounted within the latter being synchronised with said stop 105 so as to pass over the slot 115 in baffle 114, the result of which is that the beam emitted from lamp 113 passes through the optic fibres 42 so as to project the image line by line onto surface 48 of the transfer-cylinder 46, this retaining a formed image which will correspond to the transparency's dark area.
  • Pulley-diameters are such that the speed travelled by belts 91 matches the surface-speeds of both cylinders 107 and 46-48; also, the speed travelled by chain 101 -hence of detent 102- is less than that of belts 91, thus permitting correct alignment of the single tile 2 with respect to the image revolving on cyli nder 48. Fine adjustment of the tile-position thus obtained, giving perfect alignment both with the image on surface 48 and with the transparency 111 itself, is then had by working the screw-operated stretcher 122, so as to advance or retard pulley 120 (that driving chain 101) with respect to the two cylinders which bring about image-transfer: glass-cylinder 107, and transfer-cylinder 46-48.
  • the microswitch which operates stop 105 might well be cam-controlled from the end 108 of glass-cylinder 107, or from the shaft 47 of image-transfer cylinder 46-48, or from the chain's 101 drive-sprocket 103, or even from the detent 102 offered by said chain, or, indeed, from any other moving part of the machine whose operation is sychronised with said cylinders 107 and 46-48.
