Description:
“SYSTEM FOR THE IN SITU DISPOSAL OF GLASS ARTICLES”

Description Field of the invention

The present invention relates to the mechanical field and in particular to the field of equipment for the recovery and disposal of urban waste. Even more in detail, the present invention relates to a particular machinery that can be installed in urban contexts, and in both public and private spaces, suitable for allowing the in situ disposal of glass waste, in particular of bottles containing beverages, formulating said waste into granules and storing them therein to send them recovery and further uses.

Prior art

Systems, procedures and specific machinery used for the recovery and recycling of glass in general have been known for several years.

Glass recycling represents in particular a specific sector of waste recycling and consists of a plurality of operations that involve the glass waste material and that lead to obtaining the glass in a form that can make it workable and suitable for the production of new products that can be placed on the market. Glass waste is of various kinds but is essentially of industrial and urban origin.

Some cycles of recovery and recycling of “urban” glass require that used glass containers be introduced by citizens into specific containers commonly known as “bells” or collected through special door-to-door collection services or brought to glass collection areas.

In order for the collected material to be recycled, it must be previously treated in order to obtain a selected material suitable for subsequent treatments for the transformation thereof into a new finished product.

In particular, the suitably selected material must be such as to lend itself to its fusion in order to subsequently cover the function of objects with the most disparate profiles. Among the various steps of the glass recovery and transformation cycle, collection by citizens or collection by authorized personnel undoubtedly represent the most important steps for the efficiency of the entire glass transformation cycle.

One of the best known systems for collecting this material is, as mentioned above, the one that makes use of the so-called “bells”. These are known containers, with a profile similar to that of a bell, with capacities ranging from 2m 3 to 3m 3 . These containers are usually located in different points of the cities and thanks to the presence of specific calibrated holes on the outer surface thereof, they allow receiving, by insertion in said holes, glass waste materials such as bottles, jars, glasses and many other objects. Usually, for emptying such containers, a vehicle with an open body provided with crane and lifting arm is used. The frequency of emptying to be associated must be regular in order to prevent glass waste from accumulating outside the bells.

A further system for the recovery of glass waste is represented by door-to-door collection in residential and commercial structures, etc. by specialized personnel who on predefined days provide to the collection of said material.

To date there are many solutions adopted and various types of containers being tested that offer optimized performance for glass collection and which also have structural features that contribute to their aesthetic appeal, considering that these are structures generally to be positioned in predefined places in city contexts, and which should therefore harmonize with the contextual urban architecture. For this purpose, for the collection of glass, underground containers have been designed and built, for example, connected to the outside by a small column that allows the insertion of the empty bottle; containers variously sized and modular in order to be adaptable to the quantity of local population; and containers which in addition to the usual hole for the introduction of the glass material, have a further hole located at a lower height than the first in order to be able to facilitate users with disabilities.

In addition to the aforementioned, there are many solutions which, in addition to providing methods for urban storage, provide for the crushing of the glass waste material in order to make it suitable for the subsequent steps of the process for its recycling. For example, document WO2011051530 describes a glass recycling machine comprising various units such as a system for storing pieces of broken glass, a system for further grinding the glass, systems for collecting the previously ground glass, systems for the removal of materials of a different nature from that of glass and a system that allows detecting and distinguishing pieces of glass with different coloring and opacity. All in order to make a prior selection of the waste material for the subsequent processing and finishing thereof.

Document US5524837 instead describes an apparatus comprising a particular system for crushing/grinding glass waste, provided with a rotating shaft from which bars extend. Said apparatus is capable of inducing a crushing of the glass such as to obtain a subdivision thereof into parts with particle size suitable for the subsequent processing thereof.

Document JPH09248551 describes a glass processing/recycling plant, on an industrial scale, comprising peculiar systems for the removal of light materials, such as plastic parts, from the glass being processed. In addition to the above, many other solutions exist today for the collection, storage and processing of glass waste for the complete recycling thereof. Although these systems are undoubtedly effective, they necessarily involve costs associated with the various stages of the glass processing/recycling process, which result in sometimes high overall costs. Just think of the costs necessary for the construction of the containers for their collection, as well as those relating to the personnel authorized to recover the differentiated waste material and, obviously, those relating to the construction of the machinery used for the various recycling steps as well as automation and control of the entire industrial process.

It should also be recognized that, if the glass is recovered by authorized personnel, the collection operation is decidedly noisy. In fact, it must be considered that this operation necessarily implies the pouring of the glass from the collection containers into loading hoppers integrated with the transport systems of the recovered material. This recovery also takes place at set daily times, usually early in the morning, resulting in an unwanted bustle for locals and tourists. In this regard, the object of the present patent application for industrial invention is to propose a peculiar system provided with an equally peculiar glass recovery machine, integrated with systems that lend themselves not only to its collection but also to the preliminary processing steps of waste material in order to make it already selected for the subsequent processing steps in specifically dedicated sites. Said machinery is offered directly to users and is typically used for, but not limited to, the recovery, formulation in granules, storage of glass waste produced in urban contexts.

Description of the invention The present description relates to a particular system for the in situ disposal of glass waste. More in detail, the present invention relates to a system that makes use of a machine that allows, in an automated mode, the crushing on site, and therefore not in places specifically used for the disposal of waste, of glass articles.

Even more in detail, the machinery of the system according to the present invention allows the disposal of glass articles. Disposal understood as the collection of waste in collection containers and crushing thereof in the form of granules. The glass articles processed by the machinery of the subject system are generally articles used to contain food substances (especially beverages). Typically these are containers such as bottles or jars.

Advantageously, the machinery of the system according to the present invention allows the primary user to be able to carry out a substantial volumetric reduction of his/her own glass waste, allowing not only to have an equally advantageous result in terms of volume but to obtain a waste not polluted by foreign agents to the glass except for those relating to the labels and their residual glue, as well as food residues, all elements that are easily eliminated in treatment plants dedicated to the recycling of glass waste, producing a secondary raw material of absolute purity.

Advantageously, the machinery of the system according to the present invention operates in an automated mode: specifically, said machinery comprises a peculiar collection container in the form of a bottle provided with a sealed lid. To start the shredding/crushing process, the user will only have to lift the lid and insert the bottles and/or jars, one at a time. A system of rocker doors will ensure that once the bottle has been introduced, its weight will allow the opening of the door located in the middle of the inlet barrel and the consequent closure of the top door, effectively preventing the escape of dust and guaranteeing at the same time the safety of the machinery. The opening of the lid at the top of the bottle-like container automatically starts the machine through a sensor placed on its top. The shut-down, which is also automatic, is timed. After about thirty seconds of non-introduction of new bottles, the machine will switch off. The storage tank of the bottle-like container typically has, but not necessarily, a capacity of about 400 kg corresponding to about 1000 medium-sized bottles. The same includes a system of sensors that guarantee a machine stop at the filling level evaluated by triggering a lock of the head cap with the use of an electric lock, thus preventing the machinery from being used improperly. The electronic system, through dedicated software, communicates that the bottle-like container has been filled to the server of the collection center which sends a means for emptying it. The container is emptied using a vacuum designed for vitreous and particularly abrasive dusts and placed on vans provided with storage tanks. The container of the subject machinery is also provided with at least two flaps, one on the upper part of the container which preferably has the profile of a cap with a lock which, once removed, gives access to an industrial-type socket typically at 230 V, the other, with the same operation, is typically, but not necessarily, placed on the lower portion of the “bottle” and allows direct access to the container to allow it to be emptied.

Said container is provided with a shredder. The shredder containment structure is preferably made entirely of aluminum, and so is the container itself, while the shredder body is made of stainless steel. Said container comprises, in its structure, an outer casing of which at least two portions can be identified: a first lower portion with a cylindrical profile preferably made of metal, even more preferably of aluminum, and a second upper portion, shaped like a bottleneck, typically, but not necessarily, made of polycarbonate.

The machinery of the system according to the present invention provides for the bottle-like container to be fixed to the ground through a typically circular structure in the form of a concrete platform, which is made on site and on which a template is supplied and fixed for fixing the same bottle-like container. The machinery of the subject system provides that a 230 V voltage cable comes out of the platform, typically supplied by the municipal administration on whose territory the bottle will be located. The structure of the machinery provides that said cable is made to pass, through a dedicated and isolated path, inside the container in the form of a bottle and feeds all its functions.

The electrical system with which the machine is equipped is provided with a life-saving system that trips when the machine malfunctions, giving the signal to the central server which will restore the functional system.

The integrated electronic control system is mounted on a panel and has a screen on which the user can read the successful start-up and/or shutdown of the machinery and its possible shutdown due to overflow and/or malfunction as well as any other messages that the management and/or ownership of the machinery will decide to carry out. The display is visible through a polycarbonate window and the entire outer structure of the bottle is covered with a film that allows providing useful surface for advertising space. The electronic management and control system is, in some embodiments, implementable in such a way that the bottle-like collection container also has the systems to be a station for detecting data and meteorological conditions.
