Definitions

  • the invention relates to a device for manufacturing ceramic tiles, said device being provided with a mould having a lower die and an upper die, with a filling cart for introducing base material in said mould and with an endless conveyor belt, of which at least one upper part, which extends at least substantially horizontally, is movable in a direction towards and away from the mould, whilst at least two bunkers are disposed one behind the other, when seen in the direction of movement of said upper part, so as to deposit various materials on said upper part of the conveyor belt, via outlets located near the bottom side of said bunkers, whereby said materials can be deposited on base material present on the lower die by driving the conveyor belt during the movement of the conveyor belt over said lower die.
  • Such a device is known from EP-A-0,300,532.
  • a brush means is arranged near the discharge end of the conveyor belt, so as to determine the layer thickness of the material which is supplied from the bunkers on the horizontally extending upper part of the conveyor belt.
  • this device is only suitable for processing comparatively fine materials, whereby additional materials all have at least substantially the same comparatively small grain size.
  • a strickling means is disposed above the conveyor belt whose side receiving the material is provided with grooves and between the outlets of the two bunkers, so as to determine the layer thickness of the material deposited from the upstream bunker on the conveyor belt and conveyed under the outlet of the downstream bunker in the direction of the mould, whilst the downstream bunker is provided with a dosaging means for regularing the amount of material which is discharged from the downstream bunker during each operation cycle.
  • DE-A-1,170,850 there is known a device for manufacturing artificial marble, said device being provided with two bunkers. During operation material flows from the bunkers on a conveyor belt for forming two layers of material on said belt, one lying upon the other. The thickness of each layer is thereby determined by a strickling board associated with the corresponding bunker.
  • strickling boards are only possible in forming relatively thick layers of material. Contrary thereto the use of a dosaging means, makes it possible to make only a very thin upper layer, covering eventually the lowermost layer only in part.
  • the storage bunker could be provided with a plurality of compartments arranged side by side in a row, said compartments being reciprocatingly movable at least substantially in the longitudinal direction of said row.
  • the invention also relates to a method for providing striated patterns on the upper surface of tiles which are formed in a mould, whereby a layer of base material is provided on a lower die of the mould and whereby subsequently, additional material supplied from two successive bunkers is deposited on said layer of base material on a substantially horizontally extending upper part of a conveyor belt, whereby the conveyor belt is driven, in such a manner that said additional material falls from one end of the conveyor belt on the base material.
  • the object of the invention is to create a possibility of forming wispy colour patterns in the upper surface of the tiles.
  • the grooves may or may not be provided in a random pattern on the side in question of the conveyor belt, so that the material initially received in said grooves and then deposited on the upper surface of the tile will land on the upper surface of the tile in corresponding, whether or not random patterns.
  • the cross-sectional dimensions of the grooves are varied, whether or not in a randon manner.
  • a further influencing of the configuration may furthermore be effected by varying the velocity of displacement of the belt.
  • EP-A-0 312 938 there is disclosed a device for manufacturing tiles having a striped pattern.
  • said known device there is dumped on a conveyor belt a layer of a base material and on said layer of base material there is dumped additional material in various spaced strips. Then all the material lying on the conveyor belt is dumped by the conveyor belt into a funnel. From said funnel the material is discharged into moulds.
  • Also in said known device there has to be dumped a relatively great quantity of additional material on the base material for obtaining the stripe effect on the surface of the tile due to the fact that a mixing of base material and additional material will occur in the funnel.
  • Figure 1 is a diagrammatic side elevational view of a device according to the invention.
  • Figure 2 is a diagrammatic elevational view of a part of a conveyor belt to be used with the device of Figure 1.
  • Figure 3 is a diagrammatic, perspective view of a possible embodiment of a bunker to be used with the device of Figure 1.
  • the device illustrated in Figure 1 comprises a diagrammatically depicted frame 1, in which one or more lower dies 2 are reciprocatingly movable in vertical direction by means of (a) setting cylinder(s) (not shown), as is indicated by means of the arrow A.
  • a) setting cylinder(s) for each lower die 2 there is provided an upper die 3 co-operating therewith, said upper die likewise being reciprocatingly movable in vertical direction with the aid of setting means (not shown).
  • the device is furthermore provided with a bunker 4 for base material.
  • a filling cart 5 is disposed under said bunker, which is reciprocatingly movable over the frame in the direction according to the arrow B with the aid of drive means (not shown).
  • the filling cart has an opening 6 provided therein, into which opening, in the position of the filling cart 5 illustrated in Figure 1, base material can flow from the bunker 4.
  • a further filling cart 7 is disposed more or less in the extension of the filling cart 5, said further filling cart likewise being reciprocatingly movable in horizontal direction. Near one of its ends the filling cart 7 has a passage 8, a sieve 9 being disposed in the lower end of said passage.
  • a charging slide 10 is reciprocatingly movable in horizontal direction over said filling cart 7 with the aid of drive means (not shown). The charging slide 10 is thereby provided with a receiving room 11 for receiving additional material.
  • the filling cart 7 is mobile, together with a frame part (not shown), in which rollers 12 are rotatably journalled about a horizontal axis of rotation extending perpendicularly to the direction of movement of the filling cart 7. Further rollers 13 - 16 extending parallel to said roller 12 are journalled in a fixed frame part.
  • the rollers 12 - 16 function to guide an endless conveyor belt 17 in the manner illustrated in Figure 1, said conveyor belt being guided by the rollers in such a manner that the conveyor belt 17 has a horizontal part, which extends across the end of the filling cart 7 directed towards the dies 2 and 3.
  • the conveyor belt 17 is furthermore passed over a roller 18, which is vertically movable.
  • bunkers 19 and 20 are arranged above the horizontally extending part of the conveyor belt 17. Near its bottom end the bunker 20 is provided with an outlet opening, whilst a roll feeder 21 is disposed near said outlet opening. In a similar manner the bunker 19 is near its bottom side provided with an outlet opening, whilst a roll feeder 22 is disposed near said outlet opening.
  • a downwardly extending plate 23 functioning as a strickling means is disposed between the two roll feeders, said plate with its lower boundary edge at least substantially abutting against the upper side of the upper horizontal part of the conveyor belt 17.
  • the bunker 20 is intended for accommodating fine additional material
  • the bunker 19 is intended for accommodating coarser additional material having a diameter of 2 - 7 mm.
  • the dosaging means 22 consists of a roller, whose circumferential surface is is provided with fine recesses, said recesses being dimensioned such that the recesses are suitable for receiving grains of the granular material present in the bunker 19.
  • the device When the device is put into operation it will first be necessary to put the lower die 2 in a position in which the distance between the upper side of said lower die 2 and the upper surface of the frame 1, across which the filling cart 5 moves to and fro, will be at least substantially equal to the required thickness of the layer of base material to be formed on the lower die 2.
  • the filling cart 5 After the die 2 has been adjusted the filling cart 5 will be moved towards the right, when seen in Figure 1, so that material present in the recess 6 can be provided on the die 2 and also be smoothed by means of the filling cart.
  • the charging slide 10 has been placed in a position in which the receiving room 11 provided in said charging slide 10 is filled with additional material from a bunker (not shown).
  • the charging slide 10 When the sieve 9 is positioned above the lower mould the charging slide 10 is moved to and fro above the sieve, so that material accommodated in the charging slide 10 can fall from the receiving room 11, through the openings in the sieve, on the layer of base material, whereby any undesirable coarse constituents will be retained by the sieve 9.
  • strickling means 23 can be arranged with its lower edge quite close to the upper surface of the conveyor belt.
  • the quantity of granular material which can be supplied during each operating stroke of the device can be regulated by the number of revolutions the dosaging means 22 is caused to make, since the quantity per revolution of the dosaging means is at least substantially determined by the number of recesses provided in the circumferential surface of the dosaging means for receiving the granular material.
  • the material can be compressed between the lower die 2 and the upper die 3 in the required manner.
  • the upper die 3 is moved upwards again and the lower die 2 is positioned such that when the filling cart moves to the right, when seen in Figure 1, the tile now formed will be moved to the right by said filling cart, so as to be discharged.
  • a second strickling means 25 is mounted at the end of the filling cart 7, so as to strickle material present on the upper surface of the frame 1.
  • Said second strickling means 25 is thereby connected to the filling cart 7, by means of guide rods or the like, in such a manner that said second strickling means 25 can move, parallel to the direction of movement of the filling cart 7 during operation, along a very limited distance, with respect to the filling cart.
  • a conveyor belt 17 whose upper surface coming into contact with material supplied from the bunkers 19 and 20 is provided with grooves 26, as is diagrammatically depicted in Figure 2.
  • Such grooves may be provided along the entire length of the conveyor belt, whether or not in a random and erratic pattern, whilst also the cross-sectional width of the grooves may extend in a varied, preferably erratic manner along the length of the grooves.
  • the adjustment of the device will generally be such that the fine material from the bunker 20 fills the grooves, whilst at least very little of said material is present on the part of the relevant surface of the conveyor belt located between the grooves.
  • wispy patterns will be provided in the tile that is eventually manufactured.
  • the configuration of said wispy patterns can furthermore be influenced by varying the velocity of movement of the conveyor belt when the material is being deposited on the upper surface of the tile by means of the conveyor belt.
  • FIG. 3 shows an embodiment of a bunker 27, which may e.g. be used instead of a bunker 19 or 20, or for the supply of material to the charging slide 10. Near its bottom end this bunker is again provided with an outlet or dosaging means 28.
  • the bunker is built up of two parts 29 and 30 located one above the other.
  • the upper part 30 of the bunker is divided, by means of a number of division plates 31, into a number of compartments arranged in a row. Materials having different colours and/or grain sizes and the like may be deposited in the various compartments arranged side by side.
  • bunker 27 in one piece, whereby the bunker can be made to move reciprocatingly in its entirety during operation.
