Definitions

  • the present invention relates to a plant for storing, handling and feeding loose materials and to the associated operating method.
  • Granular and powdery loose materials are employed in many industries in order to produce manufactured articles or to prepare compounds or simply to supply them as raw materials.
  • These plants currently consist of a series of large silos connected to a supply source and to the user machines, constituted by presses in the specific case, by means of portions of conveyor belts which are arranged in mutual succession so as to connect the supply stations, said silos and said presses in the facilities.
  • the silos used are so tall that on installing them it is necessary to alter the building by raising the roofs.
  • the systems for storing, handling and feeding loose materials are arranged exclusively at ground level.
  • these plants are constituted by a storage area in which small low-capacity silos are accumulated, arranging them side by side and ordered in rows and columns; the materials are introduced in these silos in an already-premixed state, when required, according to percentages which can vary as necessary.
  • this storage area which in practice can be divided ideally into sectors, in each of which the materials having identical characteristics are catalogued and contained in the small silos, which are also mutually identical, automatically-controlled vehicles move along corridors provided appropriately between the rows and columns in which the silos are arranged.
  • the vehicles In response to the requests of the user machines, the vehicles first determine the sector in which the material having the required characteristics is accumulated, then remove the silos that contain it in the required amounts, and convey them for emptying and use to the inlet front of the conveyors that serve each one of the machines and onto which the material is unloaded.
  • the aim of the present invention is to solve the above-described problems of the prior art by providing a plant for storing, handling and feeding loose materials and the associated operating method which allows to considerably reduce the overall dimensions, reduces as much as possible the number of large silos and proportionally reduces the extent of any building work required for installation and of the infrastructures for connection and walking between the various regions and stations, and which allows to use materials handling means which are normally commercially available.
  • a plant for storing, handling and feeding loose materials comprising at least one filling station for containment means which can be handled by means of lifting vehicles usually known as fork-lift trucks; at least one storage area for depositing these containers in standby; a series of stations for feeding machines which use the materials; characterized in that the containment means are constituted by silos having a limited capacity and have, in a downward region, a multipurpose grid-like structure for resting on the ground, for the modular mutual stacking of the silos and for the mating of the silos with the conventional lifting elements with which fork-lift trucks are equipped, the silos being arrangeable, at least in the storage area and in the feeding stations, so as to be stacked on multiple levels.
  • the associated method for storing, handling and feeding loose materials consists in providing, in a facility, multiple small silos, each loaded with material divided according to its organoleptic characteristics and taken from a filling station; in depositing and mutually stacking the filled silos in at least one general central storage area; in conveying, by means of conventional vehicles, the filled silos between the storage area, stations for feeding user machines and vice versa; in arranging the silos in the stations on multiple stacked levels, respectively upper feeding levels and lower reserve levels; in mixing, in the stations, volumes of materials taken from the feed silos in order to obtain materials having presettable characteristics; in feeding the user machines with the materials having the preset characteristics.
  • 1 designates a plant for storing, handling and feeding loose materials.
  • the plant 1 comprises at least one filling station, generally designated by 2, for filling containment means 3 which can be handled by means of lifting vehicles 4, usually known as fork-lift trucks, which have onboard conventional weighing devices associated with the forks 4a.
  • lifting vehicles 4 usually known as fork-lift trucks
  • the filling station 2 there is at least one storage area 5 for depositing the containment means 3 on standby to be used, and there is a series of stations 6 which feed corresponding machines which use the materials, specifically presses 7 for forming ceramic tiles.
  • the containment means 3 are constituted by silos 8 which have small dimensions and a limited capacity and have, in a downward region, a multipurpose grid-like structure 8a meant for resting on the ground, for the mutual modular stacking of the silos 8 and for the mating of the silos with the conventional lifting elements, i.e., forks 4a, of the fork-lift trucks 4.
  • silos 8 which have small dimensions and a limited capacity and have, in a downward region, a multipurpose grid-like structure 8a meant for resting on the ground, for the mutual modular stacking of the silos 8 and for the mating of the silos with the conventional lifting elements, i.e., forks 4a, of the fork-lift trucks 4.
  • the silos 8 can be arranged, when they are placed in the storage area 5 and in the feeder stations 6, so as to be stacked on multiple levels.
  • Each one of the feeder stations 6 is composed of a frame 9 with at least two superimposed platforms: a first platform PT at ground level, on which a battery of reserve silos 8 is placed, and a second platform PS, which is raised and correspondingly lies above the platform PT in order to support another battery of silos 8 which, when used up, can swap places with the reserve silos; the silos 8 placed on the PS are adapted to unload the material onto conveyor means, in practice a belt conveyor 10, whose active branch 10a lies directly below the outlets of the silos 8 and whose output front 10b is located at the presses 7.
  • the conveyor 10 also has weighing elements 11; in the specific case, the weighing elements are arranged contiguously with the active branch 10a, practically almost in sliding contact with the lower face thereof, and are alternated with the unloading silos 8.
  • Screening means 12, mixing means 13 and conveyor means 14 for the processed material that is falling towards the presses 7 are further interposed, at each output front 10b of each conveyor 10, between the conveyor and the corresponding press 7 in a cascade configuration.
  • the screening means 12 are constituted by a flat screen 12a with a preset porosity and have conventional elements adapted to make them vibrate.
  • the mixing means 13 also are constituted by a conventional structure consisting of a cylindrical drum 13a which has, at its ends, respectively a loading port and an emptying port and inside which mixing paddles are fitted; the drum 13a has a rotary motion about its own axis, and the materials having different coloring and granulation/organoleptic characteristics are introduced therein.
  • the materials are then unloaded into the conveyor means 14, constituted by a hopper 15 which is internally divided into sectors 15a in order to receive and keep separate materials whose characteristics are, for each of them, homogeneous; the hopper lies above a battery of other hoppers, into which the materials are poured and which are in turn placed above the presses 7 in order to feed them with volumes of material having characteristics different from each other.
  • the multipurpose grid-like structure 8a is constituted by a flat base 8b in which there are horizontal parallel seats in which it is possible to insert the conventional forks 4a of a fork-lift truck 4; a set of four pillars 8c for supporting the silo 8 rises from the base.
  • the base 8 forms, in the lower region, a seat 8d in which it is possible to snugly place the upper edge of a silo 8 so that it is superimposed thereon.
  • the coloring materials in powder form required to provide the decorations of the tiles reach the filling station 2, being carried by the trucks 2b, in the loose state or already placed inside the respective silos 8, divided by color or mixture or particle size.
  • the silos are stacked directly inside the storage area 5, ordered by rows and columns and optionally stacked on each other, by using the fork-lift tucks 4: for this purpose, the bases 8b form, in a downward region, the seats 8d in which the corresponding upper edges of the silos 8 fit snugly in the stacked configuration.
  • the silos 8 containing the coloring materials meant to be used by the presses 7 are conveyed to the feeding stations 6.
  • the feeder silos 8 are placed on the frame 9 after being taken from the storage area 5 with the fork-lift trucks 4, whose forks 4a mate with the bases 8b, and are raised by the fork-lift trucks up to the resting level, while other corresponding reserve silos 8 are placed below them.
  • the required amounts of the coloring materials are extracted from the feeder silos 8 and are deposited in each case onto the conveyor 10 and weighed by the weighing elements 11 to check the extracted amounts.
  • the materials fall from the conveyor 10, after passing though the flat screen 12a, into the drum 13a, in which they are mixed in order to obtain the required particle size or shades of color.
  • the drum 13a discharges the treated material into the corresponding sector 15a of the hopper 15, and from there the material is in turn discharged into a designated hopper of the other hoppers that feed the presses 7 for forming the tiles.
  • the empty silos 8 are then removed and transferred to the filling station 2 to be refilled; refilling is performed by placing them sequentially below the discharge outlets of the large silos 2a; the amounts poured into the silos 8 are checked in real time by means of the weighing devices, optionally preset to required values, which are carried onboard the fork-lift trucks 4; once filling has been completed, the silos 8 are returned to the storage area 5 to wait for reuse; other full silos 8, ready to replace the feeder silos when their content is used up, are placed in the positions left free between the reserve silos, inside the stations 6.
  • All the silos 8 can have mutually different dimensions and capacities despite being used simultaneously; for example, the silos that must contain a material that is used more than the others in the production cycle can be larger, without thereby reducing the operating capacity of the plant 1.
  • the above-described invention achieves the intended aim, i.e. it allows to provide a plant for storing, handling and feeding loose materials, which is substantially more compact than the prior art, is at the same time highly flexible in its management, and can use conventional means such as fork-lift trucks and trucks for the different handling operations.
