Description

A PLANT FOR SEPARATE COLLECTION OF COMPRESSIBLE SOLIDS AND GLASS REFUSE

TECHNICAL FIELD

The invention relates to separate refuse collection.

BACKGROUND ART

In known-type systems solid compressible refuse is considered and managed in the same way as incompressible refuse, as solid compressible refuse is collected in the same containers, and is left in the same conditions as it was first acquired.

This obviously leads to an enormous waste of the space available internally of the containers.

A further negative aspect of the prior art systems for separate collection of refuse using underground containers relates to the irritating noise produced by the violent impact of the refuse made of fragile material, for example glass, against the bottom of the container or against the other, also fragile, refuse which might be present inside the container.

The considerable intensity of the noise is essentially due to the entity of the drop from the inlet zone to the deposit zone of the refuse, as well as the lack of means for softening the fall of the refuse internally of the container. DISCLOSURE OF INVENTION

The aim of the present invention is to obviate or reduce the above- mentioned drawbacks.

The aim is fully attained by the plant for differentiated collection of solid compressible refuse and glass refuse, object of the present invention, which is characterised as in the accompanying claims.

BEST MODE FOR CARRYING OUT THE INVENTION

With reference to the above-described figures, 1 denotes a central seating afforded underground, superiorly open and closable by a first lid 8, and communicating with the outside by means of a first opening 9, a second opening 10, a first turret 4 and a second turret 5; the two turrets 4, 5 being respectively dedicated for solid compressible refuse, such as for example paper or plastic, and for glass refuse constituted by bottles or objects of suitable size to be inserted in the second turret 5.

The central seating 1 is surrounded by a plurality of lateral seatings sunk underground, superiorly closed and communicating with the central seating.

Three lateral seatings of the above-mentioned plurality are represented in figures 1 and 2 and denoted by reference numbers 1 a, 1 b and 1c.

Each of the lateral seatings 1a, 1 b, 1 c houses a corresponding container, respectively 3a, 3b and 3c, destined to collect a particular type of refuse.

Means are provided internally of the central seating 1 and the lateral seatings 1 a, 1 b, 1 c for enabling translation of the containers 3a, 3b, 3c from the lateral seatings, respectively 1 a, 1 b and 1 c to the central seating 1 and vice versa.

The central seating further includes a raising system, not shown in the figures of the drawings, for vertically raising, up to the surface of the terrain, the container positioned therein, after first opening the first lid 8, which is tiltable thanks to the action of rotation organs not shown in the figures of the drawings.

In a case of solid compressible refuse of any nature, for example paper or plastic, the person who is depositing selects the container for receiving that particular type of refuse, which displaces from the appropriate lateral seating to the central seating 1 , positioning itself below the first turret 4.

When the refuse 16 has been inserted into the first turret 4 after opening a second lid 12 connected thereto via a first hinge 13, a tiltable element 14, connected to the internal wall of the first turret 4 by means of a second hinge 15, rotates from the rest position shown in figure 4 about the second hinge 15 up until it assumes a horizontal position shown in figure 5, pressing, if necessary, the refuse 16 against a truck 25 maintained in a position of complete obstruction of the first opening 9.

The truck 25 is associated to the lower part of the first turret 4 and can move transversally to the axis of the first turret 4, between the positions of complete passage and complete obstruction of the first opening 9.

The truck is of a suitable size for completely obstructing the first opening 9 and is provided with at least four grooved wheels 24 constrained to move along two guides 23 supported by two beams, for example, with a Z- shaped element 51 solidly constrained to the lower part of the first lid 8; the two guides 23 being reciprocally parallel and both having a complementary profile with respect to the circumferential groove of each of the grooved wheels 24.

The two guides 23 are also provided with endrun means, not shown in the figures, for stopping the movement of the truck 25.

The refuse 16 compacted by the tiltable element 14 is let fall internally of the underlying container, thanks to the disengagement of the truck 25 from the position of obstructing the first opening 9; the truck 25 being provided with motorised organs, not shown in the figures of the drawings, which move the truck 25 along the guides 23.

When the compacted refuse 16 has been discharged into the container, the container returns to the lateral seating provided therefor.

The tiltable element 14 is moved, for example, by a second piston-cylinder system 20 connected thereto and to the internal wall of the first turret 4 by means of, respectively, a fifth hinge 21 and a sixth hinge 22.

The tiltable element 14 has a surface area which is slightly smaller than the internal base area of the first turret 4 (figure 5).

A chute 1 1 is fixed to the internal wall of the first turret 4, the chute 1 1 being positioned above the tiltable element 14 in a rest configuration, as shown in figure 4; the chute directs the refuse 16 towards the bottom of the first turret 4.

The opening and closing operations of the second lid 12 are manually performed, or can be performed by a first piston-cylinder system 17 connected to the second lid 12 and the first turret 4 respectively by a third hinge 18 and a fourth hinge 19.

The above-mentioned tiltable element constitutes an example of presser means for compressing the compressible solid refuse contained on the truck 25 located in a total-obstruction position of the first opening 9.

A compacting apparatus 6 can be fixed to each fixed cover element 7, which overlies each lateral seating for housing a container for the collection of solid compressible refuse.

When a container bearing compressible solid refuse occupies the lateral seating reserved therefor, the overlying compacting apparatus enters into operation, enlarging as in figure 8 such as to press against the underlying refuse, and returning then to the initial rest configuration represented in figure 7.

Each compacting apparatus 6 is constituted by a pressing plate 28 and by second means for moving the pressing plate 28 from an inoperative upper position to a compressing lower position in which it compresses the refuse present in the underlying container.

In the case of glass refuse, constituted by bottles or objects of such a size as to enable insertion thereof in the second turret 5, the person inserting the refuse selects the container set aside for the collection of that type of refuse, which container displaces from the lateral seating therefor towards the central seating 1 , positioning itself below the second turret 5.

A third lid 36 is connected by a seventh hinge 39 to the upper end of the second turret 5, the third lid 36 being moved manually or by a third piston- cylinder system 40 connected to the third lid 36 and the second turret, respectively by an eighth hinge 41 and a ninth hinge 42.

At least a first inclined plane 43 and a second inclined plane 45 are fixed internally of the second turret 5, and are opposite one another, both facing downwards and superiorly covered, respectively, by a first and a second layers of rubber 44 and 46; the first inclined plane being located directly below a hole 38 of a holed element 37. The holed element 37, destined to direct each inserted bottle towards the first inclined plane 43, is fixed internally of the second turret 5, at the top thereof.

A third layer of rubber 47 is located in an adjacent position to the second layer of rubber 46, and adhering to the internal part of the second turret 5; the third layer of rubber 47 is laterally limited by two plates 48 located at a reciprocal distance which is slight greater than the diameter of a predetermined glass bottle; the two plates being designed to prevent the lateral displacement of the bottle when falling.

An L-shaped frame element 50 is located around the second opening 10, the frame element being fixed below the first lid 8.

An upper edge of a flexible sleeve 49 is stably inserted internally of the perimeter groove formed by the frame element 50 and the first lid 8, the sleeve 49 being substantially upturned truncoconical in shape; the lower opening of the sleeve 49 having a size such as to enable passage of a glass bottle 2.

Figure 9 illustrates the main stages of the fall of a glass bottle 2, from the moment when it is inserted in the hole 38, after the third lid 36 is opened, up to the depositing thereof internally of the container located below the second turret 5.

The plant of the invention enables full exploitation of the available space in the containers for compressible solid refuse to be made, thanks to the compacting of the refuse.

Further, the present plant includes special technical details which can minimise the acoustic pollution cause by the insertion of glass refuse.

The second turret 5 and the relative means for operating the turret, the compacting apparatus 6, the means for compacting the compressible refuse internally of the first turret 4 can each be part of the present plant, individually or in any combination between them.
