Description

METHOD AND PLANT FOR FORMING CERAMIC SLABS OR TILES
TECHNICAL FIELD
The present invention relates generally to a method for manufacturing ceramic tiles or slabs, and in, particular to a method for forming said slabs and the relative plant for its implementation.
BACKGROUND ART
Ceramic tile forming methods are known consisting of depositing a continuous layer of powders on a flexible belt with which walls are associated to laterally retain the powders. The belt on which said layer of powders is created is then advanced through a pressing station of continuous type, which compacts the powders on the flexible belt to obtain a coherent article of compacted powders. On termination of compacting, the article is divided into blanks, and possibly subjected to a second pressing. This method is described in detail in patent application No. RE2002A000035 in the name of the same applicant, to the text of which reference should be made for more complete information. According to the known art described in said patent application, the pressing station generally comprises both powder compacting means, in the form of rollers or compacting belts, and means for controlling the expansion of the material on termination of compacting. In both cases, said compacting means and said expansion control means are adjustable in height to enable the thickness of the article to be varied. The height adjustment of the compacting means ensures planarity of the article, and a constant compacting ratio in the transverse direction, but gives no assurance with regard to the mechanical characteristics of the article, which are a function of the maximum pressure with which the compacting means act on the powders.
In this respect, it can happen that the thickness of the strip of powders deposited on the belt varies both in the transverse direction and in the longitudinal direction either for aesthetic reasons or because of loading defects, or that for the same thickness the powders have a particle size distribution or other physical characteristics different in the transverse direction and hence are compacted to a different extent in the transverse direction.
All this means that the mechanical characteristics of the compacted article can vary both in the transverse and in the longitudinal direction until such values are achieved as not to guarantee the mechanical coherence of the article, which hence cracks and crumbles, becoming unusable.
The object of the present invention is to overcome the drawbacks of the known art within the framework of a simple and rational solution.
DISCLOSURE OF THE INVENTION
The invention attains said object by providing a method for forming ceramic tiles or slabs in which the force exerted on the powder strip is regulated during pressing.
Specifically, the method of the invention comprises at least the following operative steps: - depositing on a conveyor belt a continuous layer of powders, walls being associated with the belt for their lateral retention;
- pressing said powders to obtain a coherent article of compacted powders by advancing said belt through a pressing station of continuous type;
- controlling the force exerted on the powders during pressing. According to a preferred embodiment of the aforesaid method, the powder pressing step comprises both compacting said powders and controlling the expansion of said powders after compacting. According to the invention the force exerted on said powders during pressing can be controlled either during powder compacting alone or during powder expansion control alone or during both.
It should also be noted that the plant of the invention can be used both for obtaining a completely compacted article, and for obtaining a pre- compacted article which must then be subjected to a second pressing. The invention also includes a plant for implementing the aforesaid method. This plant comprises a conveyor belt on which a continuous strip of material in powder form is created and which is arranged to advance said strip through a pressing station provided with means for laterally retaining the material on said belt, means being associated with said pressing station to control the force exerted on said powders. According to the invention said pressing station comprises compacting means enabling the powders to be continuously compacted on the belt advancing through the station, with which said compaction control means are associated.
Said continuous compacting means can be either in the form of a compacting roller or in the form of a compacting belt. According to a preferred variant of the invention, said pressing station also comprises, downstream of said continuous compacting means, a device for controlling the expansion of the material after compaction.
The means for controlling the force exerted on the powders comprises a control unit for at least one hydraulic cylinder-piston unit with which the powder compaction means or said device for controlling material expansion after compaction are associated.
In a variant of the invention, said expansion means comprise a flexible plate, with which a plurality of hydraulic cylinder-piston units controlled by said control unit are associated. According to the invention said hydraulic cylinder-piston units can be disposed in several parallel rows to enable the force exerted on the powders to be also controlled along the powder advancement direction.
Further characteristics of the invention are defined in the claims.
To better understand the operative modalities of the method of the invention and the constructional characteristics and merits of the relative means for its implementation, reference is made hereinafter to the figures of the accompanying drawings which show by way of example a particular preferred embodiment of the plant for implementing the aforedescribed method.
Figure 1 is a schematic side section through the plant of the invention.
Figure 2 is an enlarged view of a detail of the invention.
Figure 3 is the section Ill-Ill of Figure 1.
Figure 4 is the section IV-IV of Figure 2.
Figure 5 is an enlarged view of a detail of a variant of the invention.
Figure 6 is a schematic cross-section through Figure 5. Figure 7 shows an enlarged detail of Figure 6.
Said figures show the plant 1 , which comprises a motorized lower conveyor belt 2 on which a continuous strip 100 of powders is deposited by usual devices of known type, and hence not shown.
The belt passes through a pressing station 3, the purpose of which is to compact the powders of the strip 100 to obtain an article, of substantially parallelepiped form, of coherent material.
According to the degree of pressing to which the powders on the belt are subjected, the article can form the final tile, or a pre-compacted slab which must then be subjected to a second pressing.
The article can be decorated if required and then divided into blanks of suitable dimensions depending on the final product size to be obtained.
The pressing station 3 comprises a powder compaction first zone 30, downstream of which there is a second zone 31 in which the article formed in the compaction zone 30 is decompressed.
The powder compaction zone 30 comprises two mutually superposed motorized compactor devices 4 and 5, one of which is positioned below the belt 2 and the other above it at a distance from the belt 2 which can be adjusted on the basis of the thickness of the powder strip to be compacted and of the pressure at which pressing is to be carried out.
Each of the compactors 4 and 5 is provided with a motorized roller and an idle roller, indicated respectively by the reference numerals 40, 41 and 50,
51 , about which there passes a respective band 42, 52. Between each pair of rollers 40, 41 and 50, 51 there is positioned a roller table 43 and 53, consisting of a plurality of idle rollers, the purpose of which is to maintain the bands 42 and 52 pressed to compact the strip of powder material. In the illustrated embodiment the roller table 53 is inclined in the direction of advancement of the belt 2 so as to make the compaction of the strip powders gradual.
Downstream of the roller tables 43 and 53 there are provided two opposing rollers 6 and 7, of which the roller 6 is positioned below the band 42, whereas the roller 7 is positioned above the band 43 and presses this latter against the powder strip 100 advancing on the belt 2. With reference to Figure 4 it can be seen that the roller 7 is associated with two hydraulic cylinder-piston units 8 and 9 supported by a frame 10 and arranged to transmit a controlled force to the roller 7, in order to regulate the pressure which said roller exerts on the powder strip 100. For this purpose the cylinder-piston units 8 and 9 are connected by a hydraulic circuit 11 to a control unit 12 comprising a pump 13 for delivering a fluid, typically oil, under pressure, a pressure regulating valve 14 provided with a pressure transducer in feedback, and a pressure gauge 15 measuring the pressure in the feed circuit of the cylinder-piston units. The roller 7 separates the compaction zone 30 for the powder strip 100 from the subsequent decompression zone 31 in which the powder strip 100 expands in a controlled manner to prevent cracks arising in the compacted article.
In the illustrated embodiment (Figures 2 and 3) said decompression zone 31 comprises two superposed plates 16 and 17, of which the lower plate 17 is positioned below the belt 2 and the upper plate 16 is positioned above the belt 2, in contact with the band 52. The lower plate 17 is fixed and horizontal, whereas the plate 16 is supported on a crosspiece 18 by hydraulic cylinder-piston units 19 which enable the force exerted on the powders by the plate to be regulated.
As can be seen from the figures the plate 16 can also swivel about the cylinder-piston units so that it can be inclined to the belt 2 to enable the compacted strip of powders to expand with a very small deformation gradient compatible with the intrinsic characteristics of the powders. The cylinder-piston units 19 are connected by a hydraulic circuit 21 to a control unit 20 identical with the control unit 12 shown in Figure 4. The pressing station also comprises lateral powder retention means, which in the illustrated embodiment are in the form of two parallel deformable straps 60 associated with the compactor device 5. In this respect, each of the two straps passes partially about the compactor device 5 and about deviator wheels 101 , 102 and 103. It should be noted that the deviator wheels are of adjustable distance apart, in order to be able to vary the dimension of the strip of compacted powders in the direction perpendicular to the direction of advancement of the belt in accordance with the format to be obtained. According to a variant of the invention illustrated in Figures 5, 6 and 7, the decompression zone 31 comprises a fixed body 32 supporting a flexible plate 35 via a plurality of hydraulic cylinder-piston units 36. In detail, each cylinder-piston unit comprises a cylinder, consisting of a cavity 320 present in the body 32, within which there slides a piston 321 the base of which is fixed to the flexible plate 35. The plate 35 is fixed by screws 37, each of which is received in a socket piece 38 inserted into a hole 39 in the plate 35. As can be seen from the figure, the socket piece 38 is substantially smaller than the hole 39, so that the plate can undergo small swivel movements relative to the support body 32. In practice the plane in which the plate lies during plant operation depends on the inclination of the band 52.
All the cavities 320 are connected to a hydraulic circuit 49 connected to a control unit 20.
From the aforegoing description it is apparent that, advantageously, the plate 35 behaves as an isostatic buffer, to distribute the force uniformly over the powders both in the transverse direction and in the longitudinal direction.
