Definitions

  • This invention relates to a double-loading carriage typically used for tile manufacture.
  • a layer of at least one base material generally in powder form for example atomized clay
  • loading units comprising two carriages, driven with reciprocating horizontal rectilinear movement, which are disposed on one and the other side of the mould forming cavity.
  • the clay carriage then withdraws to smooth the layer deposited in the forming cavity, then the lower die of said cavity is lowered through a predetermined amount, after which the glaze carriage advances to deposit a layer of glaze into the highest part of the cavity which has been freed following the lowering of the lower die.
  • the glaze carriage After this the glaze carriage returns to its starting position, the lower die is lowered to attain its pressing position, pressing is effected, and another loading cycle commences after extracting the tile by raising the lower die, which firstly reaches the level of the forming cavity mouth and is then lowered into the position for receiving the layer of clay.
  • the main object of this invention is to satisfy said requirement within the context of a simple, rational, reliable and low-cost construction of small space requirement.
  • Figure 1 is a sectional side view of the invention associated with a ceramic mould.
  • Figure 2 is a partial view on an enlarged scale in the direction II indicated in Figure 1.
  • Figure 3 is a section on the line III-III of Figure 2.
  • Figure 4 is a section on the line IV-IV of Figure 2.
  • Figures from 5 to 9 are views similar to that of Figure 1 but on a smaller scale, showing different significant operative positions of the carriage during the deposition of the base material.
  • Figure 10 is a view on an enlarged scale in the direction X of Figure 9.
  • Figures from 11 to 14 are views similar to those of Figures from 5 to 9, and relate to the final stages of a complete loading cycle.
  • the die plate 3 presents (at least) one forming cavity 4 the base of which is defined by a reverse face die 5 provided for moulding the laying face of the pressure-glazed tile 6 ( Figure 1).
  • the mould 6 is of the entering punch type, i.e. the die plate 3 is stationary in level, the obverse face die 55 being inserted into the cavity 4 during pressing.
  • carriage of the invention can also be used for other mould types, for example those of movable die plate type in which the die plate 3 is supported by the bed of the press 2 by way of elastically yieldable devices, and in which during the pressing operation the obverse face die 55 rests against the die plate 3 to lower it.
  • said dies 5 and 55 can be reversed compared with the illustrated arrangement, i.e. with the reverse face die 5 associated with the movable crosspiece of the press 2 and the obverse face die 55 inserted into the cavity 4.
  • a carriage according to the invention is arranged to slide forwards and rearwards on said table 1.
  • a pusher 552 to discharge the tile 6, a scraper 551 to clean the upper face of the die plate 3, and a rotary brush 550 to clean the active face of the die 55.
  • Said pusher 552, scraper 551 and brush 550 are carried by the structure of the carriage 8, and are shown schematically as they are of usual type. They are shown only in Figures 1 and 5 for simplicity.
  • the said carriage 8 comprises a flat powder guide screen 8 which rests on said table 1 and presents an aperture 10 of rectangular shape, the longitudinal axis of which is parallel to the direction of travel of the carriage 8.
  • the transverse dimension of said aperture 10 is virtually equal to the corresponding dimension of the cavity 4 ( Figure 10), whereas the longitudinal dimension of said aperture 10 is much greater than the corresponding dimension of the cavity 4 ( Figure 1).
  • a corresponding number of apertures 10 would be provided.
  • Said aperture 10 is defined by two flat opposing coplanar longitudinal strips 11 and a front transverse plate 12 coplanar to them.
  • the flat strips 11 are connected together by an overlying rear crosspiece 13 to be connected to a drive unit, not shown because of known type, for example comprising a connecting rod-crank linkage.
  • the said flat strips 11 act as runways for two dispensers 14, 16, the first 14 of which is situated on the same side as the crosspiece 13, whereas the second is positioned towards the press 2.
  • Said dispensers 14 and 15 contain respective masses of material generally in powder 140, 150 which are fed into the dispensers 14, 15 by known supply sources, not shown for simplicity, positioned above the rear end of the table 1, at the point in which (see Figure 1) the two dispensers lie at the start of a loading cycle.
  • the material 140 which can consist of one or more ceramic materials generally in powder form and not of high value, usually atomized clay, is to form the body of the tile 6, whereas the material 150, which can consist of one or more ceramic materials generally in powder form and relatively valuable, such as (at least) one ceramic glaze in powder form, is to form the exposed face of the tile, i.e. its decoration.
  • the dispenser 14 is in the form of a lowerly open bin of rectangular plan ( Figures 1-3) with its discharge mouth inserted into the aperture 10.
  • Said rectangular profile has a dimension which is virtually equal to the width of the aperture 10, and hence also to the corresponding dimension of the forming cavity 4, the other dimension, perpendicular thereto, being much less than the length of the aperture 10.
  • the illustrated dispenser 14 has a much greater capacity than the forming cavity 4 in the loading configuration of Figures 7-13, but this is not compulsory.
  • the discharge mouth of the dispenser 14 can have dimensions substantially equal to those of the forming cavity 4, the dispenser 14 can have a capacity virtually equal to that of the cavity 4 when in said loading configuration, and base material retention baffles 140, such as bars disposed transversely to the travel direction of the carriage 8, can be provided in the interior of said dispenser 14.
  • the dispenser 14 for the base material 140 (such as atomized clay) is made to slide forwards and rearwards about the screen 9 by suitable means, not shown for simplicity, for example consisting of a cylinder-piston unit, a motorized chain, an electrical actuator, or equivalent.
  • the dispenser 15 for the finishing material (such as ceramic glaze in powder form) is in the form of a hopper having a rectangular discharge mouth narrower than that of the dispenser 14 ( Figures 1-3), a dimension of said rectangular profile being virtually equal to the width of the aperture 10.
  • an outer enclosing flange 151 the front side and lateral sides of which are positioned flush with and resting on the flat strips 11 of the screen 9 ( Figures 1 and 3), its rear side being slightly spaced from said screen 9 in order to provide the seat for a gate 16 carried by the front wall of the dispenser 14.
  • plan profile of the flange 151 is preferably equal to that of the plate 12, the reason for which will be apparent hereinafter.
  • the gate 16 is opened and closed by the forward and rearward sliding of the front dispenser 15 relative to the rear dispenser 14. Said sliding is achieved, in the illustrated example, by two cylinder-piston units indicated by 17 in Figure 1, which connect the sides of the dispenser 14 to the sides of the dispenser 15. Other equivalent operating means can however be provided.
  • the invention operates substantially as follows.
  • the carriage 8 At the commencement of a loading cycle the carriage 8 is in the position shown in Figure 1, in which the dispensers 14, 15 are positioned below the respective supply sources and are closed by the table 1 and the gate 16 respectively, the lower die 5 being in the position of maximum raising to offer the previously formed tile 6 to the pusher 552.
  • the plate 12 lies outside the cavity 4 and is in contact with the die plate 3 due to the fact that the illustrated mould is of the entering punch type. If the mould is of the movable die plate type the plate 12 lies in the maximum withdrawal position of the carriage 8, completely outside the die plate 3.
  • the carriage 8 advances with the dispensers 14, 15 which remain in their previously occupied position relative to the screen 9 until the rear edge of the plate 12 is aligned with the underlying far edge (with reference to the table 1) of the cavity 4 ( Figure 5), with the pusher 552 urging the tile 6 onto the conveyor 7 (see Figure 5).
  • the screen 9 halts temporarily and the dispenser 14 receives the enabling signal to advance carrying with it the dispenser 15, which moves slightly beyond the plate 12 to lie against the scraper 551 while the front side of the flange 141 of the dispenser 14 positions itself virtually in contact with the rear edge of the plate 12 ( Figure 6).
  • the die 5 is lowered as shown in Figure 7 to release the discharge mouth of the dispenser 14. which begins to withdraw carrying with it the still closed dispenser 15 (loading 8). During said withdrawal the layer of base material 140 deposited into the cavity 4 is gradually scraped by the front edge of the flange 141 to make room for the finishing material 150.
  • the cylinder-piston units 17 cause the dispenser 15 to advance with the same speed as the withdrawal of the dispenser 14, so that the gate 16 frees the discharge mouth of the dispenser 15 and the material 150 rests temporarily on the plate 12, where it is retained laterally by the flange 151 and by the front edge of the gate 16 (see Figure 9).
  • Said loading cycle can vary with respect to that described.
  • the advancement of the dispensers 14, 15 along the screen 9 can take place simultaneously with that of the screen 9 itself, rather than after this latter has halted in the position of maximum advancement as already described with reference to Figures 5 and 6.
  • the screen 9 halts in said position of maximum advancement the configuration of Figure 6 will be obtained.
  • the rear edge of the plate 12 can lie beyond the far edge of the cavity 4 if particular parameters of the operation underway, or other requirements, necessitate it. For example this can be opportune if the powder contained in the aperture 10, and collected during the preceding advancement of the screen 9, is present in a quantity such as to hinder the correct positioning of the dispenser 14 as shown in Figure 6.
  • the opening of the dispenser 15 can take place in a different manner than that described with reference to Figures 8 and 9.
  • the two dispensers 14, 15 can begin to withdraw with the cylinder-piston units 17 shortened, then after a certain delay, for example when the central vertical axis of the dispenser 14 is close to the central vertical axis of the cavity 4, and the dispenser 15 has passed beyond the plate 12, the cylinder-piston units extend as shown in Figure 11, after which the cycle is completed as stated heretofore.
  • the reduction in operating times results not only from the fact that the base material 140 and forming material 150 are loaded in a single passage, but also from the fact that the powder guide screen 9 forms an upward prolongation of the forming cavity 4, which does not require a second intermediate lowering of the lower die 5 as is the case in the known art.
