Abstract
Description
- This invention relates to a new and original method, machine and plant for forming ceramic tiles.
- The method of the invention comprises the following operations:
- depositing a succession of downwardly orientated single or compound decorative layers on a relatively thin endless belt defining the belt of a belt conveyor,
- driving the conveyor belt in such a manner as to bring each decorative layer at a time below a lowerly-open mould die plate, and positioning the die plate on the conveyor belt such that the upper surface of this latter defines the lower surface of the mould cavity,
- loading the tile-forming material into the mould cavity, then forming a downwardly orientated tile by pressing the material above the decorative layer located on the conveyor belt.
- The invention also comprises a plant for implementing the aforesaid method, comprising:
- a conveyor with a conveyor belt of sufficiently compression-resistant material having an upper branch working on a horizontal bearing surface,
- at least one decorating machine positioned at the upstream end of the conveyor belt to spread a succession of decorative layers on the upper surface of the belt,
- a machine for forming tiles by pressing, comprising: a fixed lower base acting as a reaction base during pressing and having a horizontal bearing surface on which the conveyor belt is supported during its travel,
- the conveyor belt being driven with intermittent stepwise movement, and after each pressing operation being advanced in combination with the raising of the die plate, to remove the formed tile.
- Finally, according to the invention a forming machine is provided suitable both for forming decorated tiles by the aforesaid method and for forming tiles not by said method. Said machine comprises a fixed lower base having a horizontal bearing surface acting as a reaction base during pressing, a vertically movable member, and an upper die carried by the movable member to define the upper surface of the mould forming cavity. The machine is characterised by comprising a flat lower element of sufficiently compression-resistant material resting on the bearing surface and movable on it to act as the lower surface of the mould cavity, and further comprising a mould die plate positioned above said flat element to define the side walls of the mould cavity and movable vertically between a lower position in contact with the flat lower element and an upper position in which it is raised from the flat element to enable the formed tiles to pass below it. After each pressing operation, said flat lower element is moved horizontally in combination with the raising of the die plate, to remove the formed tile.
- The plant and machine of the invention are of particularly simple and economical construction. They are also intrinsically suitable for operation at a very high rate. The plant is also particularly short and compact in plan view.
- These and further advantages are attained by the invention as characterised in the claims.
- The invention is described in detail hereinafter with the aid of the accompanying figures, which illustrate a non-exclusive embodiment thereof.
- Figure 1 is a general schematic side view of the entire plant
- Figure 2 is a section through the downstream part of Figure 1, taken on the plane II-II.
- Figure 3 is a section on the plane III-III of Figure 1.
- Figures 4A, 4B, 4C represent three different operating stages, shown in section on the plane IV-IV of Figure 2.
- The plant of the invention comprises a
conveyor 10 with itsconveyor belt 11 of material sufficiently rigid against compression. In particular, thebelt 11 is an endless relatively thin steel belt passing about at least two end rollers, to define the belt of a belt conveyor. - Advantageously the
belt 11 is provided with two sets of regularly distributedholes 12 extending along the two longitudinal edges of the belt, to engage corresponding teeth provided on the fourend rollers 13 about which the belt passes. Theholes 12 and the corresponding teeth on therollers 13 totally prevent belt slippage on the rollers, to hence achieve perfect synchronization between the movement of the belt and the operation of the other machines which operate on it. - The
conveyor 10 has a horizontal upper branch working on a horizontal bearing surface which in its upstream part is defined by a support means 14 having an upper surface on which thebelt 11 bears. - In this upstream part there are positioned a plurality (three in the embodiment shown in the figures) of
decorating machines decorative layers 21 on the upper surface of the belt. Themachines underlying belt 11. - If a complex decoration is to be formed on the tile, consisting of a compound
decorative layer 21 formed from different superposed layers, that layer which is to form the upper layer on the tile is firstly deposited, then on this (while on the belt 11) are deposited the other layers, from the upper to the lower in turn, ie the layers are deposited on thebelt 11 in the reverse order to that followed in the traditional method, in which firstly the lower layer is deposited, then the upper layers are deposited on this in turn. - Consequently, the most downstream-positioned
machine 20A deposits on thebelt 11 that decorative layer which is to form the most outer layer on the tile, themachine 20B positioned downstream of the first deposits on each layer deposited by the preceding machine that decorative layer which is to form the intermediate layer on the tile, and finally the mostdownstream machine 20C deposits on those layers deposited by the preceding machines that decorative layer which is to form the lower layer on the tile. - The decorating machines are coordinated with each other and with the movement of the
belt 11, in such a manner as to form said decorative layers on each other with precision. - Downstream of the decorating machine there is a
machine 30 for forming tiles by pressing in a mould, the machine comprising a fixedlower base 31 acting as the reaction base during pressing and having a horizontal bearing surface on which the conveyor belt 11 bears during its travel. - The
machine 30 also comprises a usualupper die 32 which defines the upper surface of the mould forming cavity and is carried by a verticallymovable member 33 guided by lateralvertical columns 34. Themember 33 is operated by suitable known means (for example a large hydraulic cylinder-piston unit, not shown in the figures) able to provide the necessary thrust for pressing the tile within the mould die plate. - The
machine 30 also comprises ausual die plate 35 defining the lateral walls of the mould cavity. - For simplicity of description, the text will refer to the formation of a single tile per pressing operation. However (as shown in the figures), the mould can be of multiple type, ie able to form several tiles simultaneously with one pressing operation. In this case the
upper die 32 will be of multiple type comprising several dies, and likewise thedie plate 35 will comprise several cavities. - Likewise the decorative layers deposited by the
machines - The
die plate 35 is movable vertically between a lower position in contact with the upper surface of theconveyor belt 11 and an upper position in which it is raised from thebelt 11 to enable those tiles which have just been formed to pass below it. - The
die plate 35 is driven for example by four vertical cylinder-piston units 36, of which the casings are fixed to the sides of thebase 32 and the rods are fixed to the die plate itself. - The tile-forming material is loaded into the mould cavity by usual loading means, for example by a
traditional loading carriage 41 provided with a grid for homogeneous material distribution and moving with reciprocating movement along a fixedhorizontal travel surface 45. Thecarriage 41 is driven by amotor 42 with acrank 43, and is fed by ausual loading hopper 44. - According to the invention, the
travel surface 45 is positioned in line with and adjacent to the upper surface of thedie plate 35 when this rests on thebelt 11. Thesurface 45 is defined by the upper surface of a thin fixedhorizontal panel 46 positioned transversely above thebelt 11 in the region immediately upstream of themachine 30, and spaced from the belt and from the decorative layers lying on it. - The described plant implements the following method.
- The
conveyor belt 11 is driven with intermittent motion. - The
machines - The decorative layers are deposited directly onto the upper surface of the
conveyor belt 11. To prevent said layers remaining adhering to thebelt 11, the belt upper surface can be coated with a non-adhesion material, such as a fluoroethylene (TEFLONR). - Said decorative layers can be deposited on the
belt 11 while this is in movement if themachines belt 11 must be at rest. - Each single or compound decorative layer 21 (see Figure 2) is then carried by the
belt 11 to below thedie plate 35 of themachine 30, where it stops. During this stoppage a tile (possibly multiple) is formed. - When the
belt 11 carries a decorative layer to below thedie plate 35, this latter is raised form thebelt 11 and thedie 32 is raised (see Figure 4C). Thedie plate 35 is then lowered onto thebelt 11, the upper surface of this latter (which carries the decorative layer) then defining the lower surface of the mould cavity. At this point the described loading means load the material into the mould cavity above the decorative layer (see Figure 3). - Immediately afterwards, the
upper die 32 is lowered into the die plate cavity and the material is pressed onto thebelt 11 together with the decorative layer, with the pressure necessary to obtain atile 9 with the required degree of compaction (see Figure 4A). The result is a tile 9 (possibly multiple) already provided with the decorative layer, and with its exposed face orientated downwards. This exposed face is shaped by the upper surface of thebelt 11. - Immediately afterwards, the
die plate 35 and theupper die 32 are raised into their initial position to enable the tile which has just been formed to pass below the die plate. Specifically, to achieve correct extraction of thetile 9 from thedie plate 35, the die plate is firstly raised while the die 32 remains at rest, to press thetile 9 against the belt 11 (see Figure 4B), with the result that the tile is urged and guided out of thedie plate 35. Thedie plate 35 is then further withdrawn from thebelt 11, and thebelt 11 is driven one step forwards to move the just formedtile 9 out of the machine 30 (see Figure 4C). - The machine of the invention is particularly suitable for implementing the described method by which decorated tiles (unfired) are formed. However the machine is also suitable for other methods, for example for forming undecorated tiles. Moreover, instead of the described
flexible steel belt 11, the machine can comprise a different flat element of a sufficiently compression-resistant material which rests on the bearing surface of thelower base 31 and is movable along it, to act as the lower surface of the mould cavity (as a substitute for the belt 11). - Numerous modifications of a practical and applicational nature can be made to the invention, but without leaving the scope of the inventive idea as claimed below.
and a mould die plate defining the side walls of the mould cavity and movable vertically between a lower position in contact with the upper surface of said conveyor belt and an upper position in which it is raised from the conveyor belt to enable the formed tiles to pass below it,
