Description: REFUSE RECYCLING APPARATUS DESCRIPTION Technical Field This invention concerns a new electromechanical apparatus, electronically aut iiiαi J, multifunctional and multisystem, dedicated to the sector of pollution prevention. It works on four main functions, independent of each other insofar each function can be activated in total autonomy or simultaneously with the other ones, as they are fully electronically automated by their own functionality and are equipped with a safety electronic system. The apparatus is so designed to grant the sorting, compacting and collection in appropriate separated containers for solid city waste, in the places where they are produced; in detail they are glass, ceramics, plastics, polystyrene, plate, aluminium, paperboard, paper. Disclosure ofthe Invention To comply with the requirements of the specific problem, the apparatus has been therefore designed in three basic versions, namely: a) Electric utensil version - for family use; b) Medium apparatus version - for small joint owner communities, pubs, restaurants, shops and any other medium consumer, c) Big apparatus version - for large joint owner communities, hotels, catering, mess rooms, hospitals, barracks and any other large consumer. The apparatus, according to this invention, aims at the following results: 1) progressive elimination of road trash containers, that are presently in use, spread everywhere and causing environmental and atmospheric pollution; 2) progressive elimination of glass collection bells; 3) progressive disuse of open air waste dumps, leaving only a small number of them in activity for the collection of inert waste and durables; 4) progressive dismantlement of most incinerators, presently in activity or a-building; 5) realization of big savings derived from reduced transport to and from waste dumps and/or incinerators, specially if placed outside district; 6) elimination of a conspicuous percentage of local rates for the collection and disposal of city waste; 7) progressive medium term recovery of solid waste to be recycled up to 90% approx. The environmental improvement will be the natural consequence of the progressive employment ofthe above mentioned apparatus; as a matter of fact very small financial engagements, transfered from savings, will be sufficient for bringing to life a healthier environment, a better way of living for the comfort of everybody. The above listed aims, and other that will be brought to evidence here below, are attained by means of this apparatus, characterized in that it comprises, within one single case, four devices that are suitable to perform fully automated functions, such as to grant four different treatments of the entered solid city waste, in absolutely safe conditions and without external development of gases, smokes and exceeding noise, as the same is insulated Brief Description ofthe Drawings These characteristics, and other more of functional and executional nature, of the new apparatus, that forms the object of the present industrial invention, shall be better comprehended by reading the following description regarding an example of realization of the same apparatus that is illustrated at merely indicative title, in the annexed drawings, wherein. Fig 1 is a top view that schematically represents the apparatus with a section of the outside case, enabling to see the location of the four solid city waste sorting and treatment devices, as well as the devices and systems for their collection and treatment, Fig 2 is a side view of the inside of the glass and ceramics treatment device (first function) ofthe apparatus according to the invention, Fig 3 is a front view ofthe inside of device in fig. 2, Fig 4 is a side view of the inside ofthe plastics and polystyrene treatment device (second function) of the apparatus according to the invention, Fig 5 is a front view ofthe inside of device in fig 4, Fig 6 is a side view of the inside of the aluminium and plate treatment device (third function) ofthe apparatus according to the invention, Fig 7 is a front view ofthe inside of device in fig 6, Fig 8 is a side view of the inside of the paper and paperboard treatment device (fourth function) ofthe apparatus according to the invention, Fig 9 is a front view ofthe inside of device in fig 8, Fig 10 illustrates the basement of the outside case of the apparatus according to the invention, suitable to contain the four devices for the separate treatment of waste, Fig 1 1 illustrates a container for the treated waste and the relevant guiding means Descπption ofthe Preferred Embodiment With specific reference to the above listed figures, it is possible to observe that the apparatus is internally divided into four sectors of equal dimensions, each one corresponding to its specific equipment for the distinguished treatment of the solid city waste to be treated, as well as for its collection after treatment, namely A) Glass-Ceramics Sector, B) Plastics-Polystyrene Sector, C) Aluminium-Plate Sector, D) Paper-Paperboard Sector The apparatus consists of an external metal case (1) realized in sheet iron with the shape of a rectangular parallelepipedon with a soundproof interspace (2), inside which the four load bearing structures are arranged, independent of each other, respectively relevant to the four devices, as well as the relating electromechanical and electronic parts and the motion transmission systems Under the case basement there are arranged four spheroidal rubber-coated omnidirectional wheels (3) and a floor fixing vibration-damping system (4). in the lowei part ofthe case (1) are lodged the four containers (Al, Bl, Cl, Dl), extractible, suitable to contain the sorted solid waste after treatment Such containers are provided with small omnidirectional rubber-coated wheels and can be extracted from the case (1) of the apparatus with the aid of guiding tracks (5) fixed to the same base Each container corresponds to a specific function of the apparatus, being equipped within its inside with suitable compartments for the reception ofthe solid waste treated within the functionally connected device Each container is therefore provided with identification means that grant its correct attachment into the apparatus Said containers (A1- B1- C1. D1) have standard dimensions and are provided with joints to fix one another superimposed for transport on vehicles; they are also suitable to be washed and disinfected by means of mechanized washing and disinfection systems The apparatus according to this invention consists of an ensemble of functional devices for the distinguished treatment of solid city waste and provides - for the treatment of glass and ceramics (first function) - a device (6) inside which is arranged an electronic photocell system (7) connected with a timer (8) that induces the opening of the loading port (9) with an internal semicircular rotation, such rotation is controlled by an electric micromotor (10) All this is induced by the interruption of the electronic photocell beam, provided approaching of the solid material to be disposed into the loading cell ofthe device (6) After a few seconds from the disposal ofthe solid, the port (9) closes under the control ofthe timer (8), while moving, the port (9) activates a sensor that starts the electric motor (11) This electronic starting system of the device is also provided in the other three devices of the apparatus, and, therefore, it will be briefly and simply called "Automated electronic inlet and treatment phase starting system" At this moment starts the process of treatment of the solid, that is divided into three distinguished phases, namely Phase a) Pressofractionation Two toothed wheels with internal helicoid (12) are provided in suitable protrusions by the sides of a cilindrical piston (13), both wheels engage two worm shafts (14) which, driven by toothed wheels (15) connected to the transmission of the motor shaft with a toothed belt system (16), grant the ramming movement of the newly designed piston (17), that includes within "its head" four small cylindrical rammers (17a) provided with specially shaped heads in hardened steel, that can perform cadenced percussions on the solids to be treated. The combined action of the pressing piston (17) with the cadenced percussions of the rammers ( 17a) arranged within its body, grants the demolition and fractionation of glass and/or ceramic solids being treated. The piston (17) at stroke end impacts an electronic sensor that stops the stroke with the rotational inversion of motion, so inducing it back to starting position. During the return phase the piston opens a small hopper inlet (18) where the splinters of the phase product fall together by gravity. The opening of the small hopper port (18a) is controlled by the piston movement by coupling and releasing a lever system. Phase b) Pressotrituration. Connected under the decentered hopper (18), there is assembled a special worm triturator for glass and ceramics (19) suitable to transform the fractionated mateπals into extra fine fragments. These, little by little are conveyed to a particular product selecting revolver (20), consisting of a threaded lock ring, a revolver drum with four terminal holes corresponding to four oriented chute pipes (21), each one leading to a compartment of the container. This artifice grants the possibility to stock in one single container with four compartments three kinds of glass differring in colour, in order to facilitate the work ofthe recycling concerns, whereas the fourth compartment is reserved to stocking the treated ceramic waste. The apparatus according to this invention moreover provides - for the treatment of plastics and polystyrene (second function) - a device (6a), which also employs the above mentioned "automated electronic inlet and treatment phase starting system". This device includes within its inside the functional means that are suitable to perform the foreseen operational phases, namely: Phase a) - Pressofractionation: Two worm shafts (22) driven by means of toothed wheels (23), connected with the shaft (24) of the motor (I la), bring forward the special cylindrical piston (25) bearing on its sides in correspondence with the worms two toothed wheels with internal helicoid, that, engaging the worms, grant the horizontal pressing movement of the piston (25). The letter, that has a particularly shaped head, presses the solid object to be treated (i.e. a plastic bottle) against a three-bladed propeller shear with cutting edges (26) and particular profile, corresponding to the negative profile of the piston head (25). The shear, turning at higher speed than the pressing piston (25) forward movement, grants the disintegration of the object under treatment. At the stroke end, the piston (25) impacts a rotation inversion sensor that induces its return to starting position in order to receive and treat other solids. Phase b) - Fine Trituration. The disintegrated solids, by gravity, reach the gears and blades of two special triturating rollers (27), thus receiving a further fine trituration treatment Phase c) - Selection-Stocking. The cuttings produced with the combined actions of the treatment phases a) and b) fall by gravity into a two way platform scale (28) that is induced to opening position by an electronic photocell-relay system. The product is then conveyed to its own compartment within the container (Bl .) and becomes consequently ready for periodical collection for recycling purposes. The apparatus according to this invention also provides - for the treatment of aluminium and plate (third function) - a device (6b), which also employs the above mentioned "automated electronic inlet and treatment phase starting system". Such device includes, within its inside, the functional means that are suitable to the execution of the foreseen operation phases, namely: Phase a) - Piercing Compactification. The working phase of this function consists of a presso-compacting action on the solid to be tιe<dcU, originated from a particular piston (29), sliding by mean*? of two toothed wheels with internal helicoid (30), that are integral within the piston (29), with two worms (31 ) working as bearing and drive shafts, connected by means of toothed gears (32) and with belt transmission (33) to the shaft (34) of the electric motor (l ib). The piston (29), with cylindrical shape, is provided on its head with a particular riveting (29a) for piercing, during the pressing action, tight containers (e.g. aerosol bombs and spray dispensers, etc.) of plate and aluminium, that, should they be compacted without being pierced simultaneously, might cause explosions. The advancing piston pushes, pierces and compresses the solid under treatment against a plate with shock absorbing counterplate (35), mounted on expansion springs, that compacts it to a few millimeter thickness. Once the pressing phase is exhausted, the piston returns to its starting position by means of an electronic control sensor. Phase b) - Stocking. During this phase a two way scale (36), controlled through an electromagnetic recognition system (36a), is oriented through a relais to the specific compartment in the container where the compacted metallic waste will be disposed. The apparatus according to this invention also provides - for the treatment of paper and paper board (fourth function) - a device (6c) ), which also employs the above mentioned "automated electronic inlet and treatment phase starting system". Such device includes within its inside the functional means that are suitable to perform the foreseen operational phases, namely. Phase a) - Compactification Starting the electric motor (l ie) drives a number of toothed wheels coupled to a circular cam (37); a set of guided rods (38) connects them generating a rectilinear motion that ensure the maximum synchronism between the upper impacting piston (39) with rectangular sectioned head (39a) and the lower trimming piston (40), also having a rectangular sectioned head with punching grid (40a), positioned by means of a cam at 180° from each other. In fact the upper piston begins the pressing stroke by pushing the solid under treatment (e.g. paper board container and/or magazines) against an adjustable dampening expansion plate (41). During the phase of the upper piston return (39), the compacted solid falls by gravity ino the lower bin, where the shearing piston (40) is open at its maximum width, and then begins the advance phase Phase b) - Shearing. The lower piston with rectangular shape (40), that bears on its head a particular "male" punching grid (40a), receives the compacted material and pushes it against a receiving "female" grid (42) shearing it to extra fine pieces. The receiving "female" grid (42) is arranged on an expanding system with adjustable calibration. Phase c) - Stocking. The fragments, obtained as above from the shearing treatment, fall by gravity into the container underneath (D.1), so becoming ready for collection in view of recycling. From the above description and from the annexed drawings, the qualities of practicability, functionality and economy ofthe apparatus for the treatment of solid city waste being the object ofthe present industrial invention, can be easily noticed. The apparatus and its component parts are here described and represented merely as an indicative non-limiting example and in any case with the only purpose of proving the actual realizability and the characteristics ofthe present invention. From these premises it is possible to infer that the apparatus in object and the method of employment ofthe same may be subject to several variants and modifications, according to the specific requirements of each single case, as well as suggested by practical experience. Such variants may concern both the above mentioned functional parts, and their assembling and employment peculiarity, without passing the limits of the present invention.
