Method and apparatus for storing rubbish in a motor-vehicle intended for differentiated collection of the same

Abstract: A motor vehicle (6) intended for differentiated collection of rubbish carries an apparatus (1) for storing the same, comprising a holding container (2) subdivided by a dividing baffle (3) into a first and a second conveying chamber (4,5). The dividing baffle presents an orientable portion (14) which can be placed in various positions to distribute the volume of the holding container (2) increasing the volume of the first or of the second conveying chamber (4,5) according to the quantity of waste inserted. The waste is expelled from the holding container (2) through outlet openings (19,20) provided with closure doors (21,22) able to be opened independently from each other to allow the operator to empty the conveying chambers (4,5) according to a desired sequence.

Description: The present invention relates to a method for storing rubbish on a motor vehicle intended for differentiated collection of the same, comprising the characteristics expressed in the preamble to claim 1. The present invention also relates to an apparatus for storing rubbish on a motor vehicle intended for differentiated collection of the same, comprising the characteristics expressed in the preamble to claim 9. As is well known, the differentiated collection of solid urban or other kinds of waste consists of collecting different types of waste, separately from each other, in such a way as to facilitate the disposal and/or recycling operations of the waste. More specifically, waste is normally conveyed into collecting bins which are able to be periodically emptied onto motor vehicles intended for transportation of the waste itself to treatment and/or disposal locations. For this purpose the use is known of motor vehicles provided with a holding container subdivided internal by a dividing baffle into an upper conveying chamber and a lower conveying chamber. A hopper is fitted on the motor vehicle ahead of the holding container to convey inside the upper and lower conveying chambers, respectively, a first and a second type of waste emptied, simultaneously or in successive phases, from one or more of the aforesaid bins. From the side opposite to the hopper, the holding container presents an outlet opening whereto is associated a closure door subdivided into an upper semi-part and a lower semi-part. The upper semi-part of the closure door, hinged in the upper part of the holding container, can be opened independently from the lower semi-part, whereas the latter can only be opened together with the upper semi-part. The lower semi-part is opened with the aid of latching means which retain the semi-parts united together whilst lifting means act on the upper semi-part to lift the entire door. The dividing baffle of the holding container presents a fixed portion which extends horizontally along the container itself and an orientable portion, hinged to the fixed portion on the side opposite to the hopper and presenting a terminal edge adjacent to an inner surface of the door. This inner surface develops according to an arched profile concentric to the hinge axis of the orientable portion. Moreover, the orientable portion can be selectively placed in a position of coplanarity with the fixed portion or in a first and a second deviated position respectively opposite, wherein the orientable portion is set perpendicularly with respect to the fixed portion, thereby determining the increase in the capacity of one or the other conveying chambers. In the coplanar position, the orientable portion divides the outlet opening into an upper portion and a lower portion communicating respectively with the upper semi-part and the lower semi-part of the closure door. When the orientable portion of the dividing baffle is set in the first or in the second deviated position, the outlet opening communicates only with one of the two conveying chambers, involving the entire development of the closure door. If storage of the first and of the second type of waste is expected in roughly equal quantities, before performing the normal work shift, the orientable portion of the dividing baffle is set in the coplanar position. Vice versa, if one type of waste is expected to be stored in larger quantity than the other, the orientable portion is set in the first or in the second deviated position. The apparatuses for the differentiated collection of waste described above present a very reduced operating flexibility, since the choice of position of the orientable portion is limited exclusively to three different volume distributions of the holding container, corresponding for instance to percentage ratios of 50/50, 60/40 and 40/60 between the two conveying chambers, without any possibility of obtaining intermediate distributions among the three values designed by the manufacturer. It is also necessary to forecast the quantity of different waste to be stored during the work shift in order to set the orientable portion of the dividing baffle beforehand according to the correct position. It should also be considered that the quantity of waste accumulated in the various collection points can change within a very short time span and, therefore, it is not easy to predict exactly which type of waste may be collected in greater quantity. Another problem of considerable importance noted by the Applicant is linked to the opening of the off-loading door, whose upper portion can be opened independently from the lower one, whilst the latter can only be opened together with the upper one. Consequently, when the orientable portion of the baffle is in the coplanar position, the operator is forced to off-load first the upper conveying chamber even when he is nearer to a collecting post for the waste contained in the lower conveying chamber. When the orientable portion of the dividing baffle is in the first or in the second deviated position, the operator is forced to empty first the conveying chamber made more capacious by virtue of the position presented by the orientable portion itself. In essence it is never possible to choose which holding chamber is to be emptied first, since the position of the orientable portion of the dividing baffle determines the order of emptying. Document US 5,584,642 shows an apparatus for storing rubbish comprising a container divided in an upper and a lower conveying chambers by an orientable portion. An actuator is operatively engaged to the orientable portion for thrusting this latter towards the lower conveying chamber. When the degree of filling of the lower conveying chamber reaches a predetermined value, the thrust action exerted by the refuse become greater than the thrust force exerted by the orientable portion, which is consequently pushed towards the upper conveying chamber, thus increasing the volume of the lower conveying chamber. Moreover the relative volumes of the upper and lower chambers can "self adjust" in response to the actual volumes of refuse placed into the vehicle. Document WO 97/45292 shows an apparatus exhibiting a lower conveying chamber and at least an upper conveying chamber divided each other by a dividing baffle designed to be lowered for facilitating the expulsion of waste from the upper chamber, once the lower chamber has been already emptied. The dividing baffle is also positionable upward and downward between two extreme positions for increasing the volume of one or the other conveying chamber. The positioning operation of the baffle requires to add or remove some heavy components, and may be achieved only when the vehicle stands still in a garage. Document US 5,316,430 shows an apparatus comprising a telescopic L-shaped dividing baffle which is movable towards one or the other conveying chamber to increase, when necessary, the volume of the one or the other conveying chamber. The volume adjustment is achieved by an operator which must visually control the degree of fullness of the conveying chambers. The object of the present invention is essentially to solve the problems of the prior art, proposing a method and an apparatus for storing rubbish in a motor vehicle intended for differentiated collection, with which it is possible to manage in a timely fashion the volumes of the conveying chambers according to the different quantities of waste loaded, also enabling to choose according to the needs at hand the sequence whereby the conveying chambers are emptied. This aim and others besides which shall become more readily apparent in the course of the present description, are essentially attained by a method for storing rubbish in a motor vehicle intended for differentiated collection of the same comprising the characteristics expressed in the characterising part of claim 1. According to the present invention, the aforesaid method is embodied with a rubbish storage apparatus mounted on a motor vehicle for the differentiated collection of the same, comprising the characteristics expressed in the characterising part of claim 9. Additional features and advantages shall become more readily available from the detailed description of a preferred, but not exclusive, embodiment of a method and of an apparatus for storing rubbish on a motor vehicle intended for differentiated collection of the same, according to the present invention. This description shall be made hereafter with reference to the accompanying drawings, provided purely by way of non limiting example, wherein: Figure 1 shows a motor vehicle intended for differentiated collection of rubbish with a storage apparatus according to the invention shown in longitudinal section; Figure 2 highlights in section the storing apparatus with a first outlet door open to allow emptying a first conveying chamber; Figure 3 highlights in section the storing apparatus with a second closure door open for the expulsion of the rubbish contained in the second conveying chamber. With reference to the aforesaid figures, the number 1 indicates in its entirety an apparatus for storing rubbish on a motor vehicle intended for differentiated collection of the same, operating according to a rubbish storing method in accordance with the present invention. The storing apparatus 1 comprises at least one holding container 2 presenting internally at least one dividing baffle 3 which delimits, in the container itself, a first conveying chamber 4, for instance positioned higher, and a second conveying chamber 5 positioned lower. As can be seen from the figures, the holding container 2 is positioned at the rear of a motor vehicle 6 intended for differentiated rubbish collection, equipped with a loading hopper 7 interposed between the container itself and a driver's cab 6a of the motor vehicle 6. The loading hopper 7 is set to receive the rubbish coming out of a bin (not shown in the figures) which, by means of a gripping and upsetting device 8 known in itself, is picked up from the ground and upset above the hopper itself causing the rubbish to fall thereinto. In the loading hopper 7 are present first and second transfer means, only partially shown in figures 2 and 3 because they can be constructed in a known way, comprising for instance respective thrusters 9a, 9b which selectively transfer the first and the second waste respectively into the first and into the second conveying chamber 4, 5, through a first and a second inlet opening 10, 11, associated to a front wall 12 of the holding container 2. The first and the second waste are thus continually inserted in the respective conveying chambers 4, 5 until suitable sensor means detect and indicate that a pre-set degree of filling has been reached in one and/or in the other conveying chamber 4, 5. The sensor means are not described in detail or shown since they can be made in any convenient manner by the technician versed in the art. For instance, such sensor means may comprise pressure transducers operating in a way known in itself on the hydraulic circuits actuating the transfer means 9a, 9b. The transducers are able to emit a signal when, once the pre-set degree of filling of one of the conveying chambers 4, 5 is reached, there is an increase in the pressure of the hydraulic circuit of the respective transfer means 9a, 9b due to the greater thrust which must be imparted to transfer and compact the waste in the chamber itself. According to the present invention, the apparatus 1 further comprises driving means 13 operating on the dividing baffle 3 to adapt selectively the volume of the conveying chambers 4, 5 to the quantity of the first and of the second waste stored. More in particular, the driving means 13 preferably operate on an orientable portion 14 of the dividing baffle 3, positioned in the lower part of the holding container 2 and hinged according to a horizontal axis to a fixed portion 15 of the dividing baffle itself. In the embodiment shown in the drawings, the driving means 13 comprise one or more hydraulic actuators 16 engaged externally to the holding container 2 and operating on lateral pins 17 projecting from the orientable portion 14 through respective arched slots 18 obtained on the walls of the holding container 2. The arched slots 18 present a curvilinear development concentric to the hinge axis of the orientable portion 14 of the dividing baffle 3. The driving means 13 may be set to position the orientable portion 14 of the dividing baffle 3 in a plurality of intermediate positions "C" comprised between a first and a second limit position "A", "B", as can be seen in Figure 1. In the first limit position "A", the orientable portion 14 is inclined upward with respect to the fixed portion 15, minimising the capacity of the first conveying chamber 4. Conversely, when it is situated in the second limit position "B", the orientable portion 14 is inclined downward with respect to the fixed portion 15, thereby minimising the volume of the second conveying chamber 5. Between the first and second limit position "A", "B" and the various intermediate positions "C", an emptying position "D" (visible in Figures 2 and 3) is further defined, wherein the orientable portion 14 is coplanar with respect to the fixed portion 15. Moreover, support means 30 are preferably provided associated to the orientable portion 14 of the dividing baffle 3 and operatively connected to the holding container 2 to support the orientable portion itself thereby compensating at least partially for its weight. Such support means 30 can for instance comprise torsion bars or other elastic organs, such as springs 31 engaged externally to the holding container 2 and operating on the lateral pins 17 or on auxiliary lateral pins 32 of the orientable portion 14. Such auxiliary pins are preferably guided along respective curved slots 33 obtained in proximity to the hinge axis of the orientable portion 14, for instance at a distance not exceeding 1/10 of the distance between the hinge axis itself and a terminal edge 24 of the orientable portion 14. The springs 31 are thus subjected to relatively small deformations as a result of the excursion performed by the orientable portion 14. It is thereby possible to ensure that the elastic reaction exerted by the springs 31 maintains a value suitable to balance the weight of the orientable portion 14, without undergoing subsequent changes as a result of the movements made by the latter. Opposite to the first and the second inlet opening 10, 11, on the holding container 2 are present a first and a second outlet opening 19, 20 respectively provided with a first and a second closure door 21, 22. The first and the second outlet opening 19, 20 are preferably delimited from each other, in correspondence with a common delimiting edge, by means at least of one transverse bar 23 engaged to the rear end of the holding container 2, in coincidence with the terminal edge 24 of the orientable portion 14 when the container is in the emptying condition "D". Both the first and the second closure door 21, 22 extend consecutively according to an arched profile concentric to the hinge axis of the orientable portion 14 of the dividing baffle 3. In the embodiment shown, the first door 21 is arched according to the description above in its lower semi-part 21a, whilst an upper semi-part 21b thereof, hinged on the upper part of the holding container 2 presents a square right angle profile which allows for greater exploitation of the volume of the holding container itself. The second door 22 is entirely shaped according to an arched profile, and it is oscillatorily hinged below the transverse bar 23. The arched profile of the closure doors 21, 22 ensures that the terminal edge 24 of the orientable portion 14 essentially remains in contact on the arched surfaces of the doors themselves, guaranteeing an effective mutual separation of the first and of the second waste in any operative position assumed by the orientable portion itself. It is possible to use closure doors 21, 22 with a profile differing from the description above, setting the terminal edge 24 on a bulkhead movable telescopically with respect to the orientable portion 14 and positioned as an extension thereto. First and second opening means 25, 26 comprising for instance first and second hydraulic opening actuators 27, 28, are associated respectively to the first and to the second closure door 21, 22 to open them independently from each other. In accordance with the storing method according to the invention, the operation of the subject apparatus 1 is the following. During the performance of the usual work shift, the first and the second waste emptied from the bins are progressively inserted respectively into the first and into the second conveying chamber 4, 5. In a way known in itself, the first and the second transfer means 9a, 9b are able to transfer the first and the second waste into the respective conveying chambers 4, 5 compacting them to an increasing extent, thereby progressively increasing the degree of filling of the chambers themselves even after their entire volume is occupied. The progressive compacting of the waste in the first or, respectively, in the second conveying chamber 4, 5 determines a progressive increase of the thrust which the transfer means 9a, 9b need to impart to compact additional waste in the chamber itself, and a corresponding pressure increase in the hydraulic circuit associated to the transfer means themselves. When the pressure increase in the hydraulic circuit associated respectively to the first and to the second transfer means 9a, 9b exceeds a pre-determined threshold, the aforesaid sensor means detect and indicate that the pre-set degree of filling has been reached in the corresponding conveying chamber 4, 5. The indication of the sensor means can be sent directly to the driver of the motor vehicle 6, or to an electronic control unit, thereby determining, respectively upon command from the driver or from the control unit, the possible intervention of the driving means 13 associated to the orientable portion 14 of the dividing baffle 3. Upon command of the driving actuators 16, the orientable portion 14 shall be moved according to a pre-set motion step or in any other way able to increase to a pre-determined extent the capacity of the conveying chamber 4, 5 which has reached the pre-set degree of filling. Assuming for instance that the first conveying chamber 4 has been filled, the orientable portion 14, initially placed in the emptying position "D", shall be moved downward to the next intermediate position. The displacement of the orientable portion 14 towards the second conveying chamber 5 may be repeated, in the course of the work shift, every time the attainment of the pre-set degree of filling is detected in the first conveying chamber 4 in the way described above. Alternatively to what has been described above, it is also possible for the driving means 13 to remain essentially inactive during waste collection, and for the orientable portion 14, balanced by the compensation means 30, to be left free to move spontaneously inside the holding chamber 2 to adapt the volume of the conveying chambers 4, 5 to the quantities of first and second waste inserted. More specifically the orientable portion 14, adequately balanced by the compensation means 30 that cancel its weight, is subjected to the thrust imparted on its opposite sides by the first and by the second waste compacted respectively in the first and in the second conveying chamber 4, 5. Under this circumstance, as soon as the degree of filling in one of the conveying chambers 4, 5 and thus the compaction and the thrust imparted by the respective waste, exceeds the degree of filling of the other chamber, the orientable portion 14 spontaneously moves under the effect of the thrust imparted by the waste present in the fuller chamber, increasing its volume until the thrusts imparted respectively by the first and by the second waste return to being essentially equal. When the aforementioned sensor means detect that both the first and the second conveying chamber 4, 5 have reached the pre-set level of filling, it is necessary to empty the waste from the holding container 2 in correspondence with the locations destined to treat and/or recycle the waste itself. To this end, the orientable portion 14 of the dividing baffle 3 is brought, upon command of the driving actuators 16, to the emptying position "D", with its own terminal edge 24 coinciding with the common delimitation edge of the outlet openings 19, 20, as shown in Figures 2 and 3. Under this circumstance, the orientable portion 14 determines a further compaction of the waste contained in the first conveying chamber 4 or anyway in the chamber whose internal volume had previously been increased during the execution of the work shift. The use of the orientable portion 14 as a compaction means is also made possible by the fact that the degree of compaction conferred to the waste by the transfer means decreases progressively starting from the front wall 12 of the holding container 2 towards its rear part. The possibility is not to be excluded of providing, in association with the orientable portion 14, additional compacting means to compact the waste contained in one or the other conveying chamber 4, 5 in order to allow and/or facilitate the movement of the orientable portion itself towards the emptying position "D". After the orientable portion 14 of the dividing baffle 3 has been placed in the emptying position "D", the operator may advantageously decide according to his needs whether to empty one or the other conveying chamber 4, 5 first. The motor vehicle is driven to the location set to receive the waste which the operator has decided to off-load first, whereupon the closure door 21, 22 of the conveying chamber 4, 5 containing the waste to be expelled is opened. Subsequently this waste is expelled through the respective outlet opening 19, 20, for instance with the aid of an expulsion 29a, 29b known in itself, associated to the respective transfer means 9a, 9b and movable together thereto along the holding container 2. The closure door 21, 22 is subsequently closed again, whereupon the motor vehicle 6 moves to the place destined to receive the waste still present within the holding container 2. Once this location is reached, the closure door 21, 22, not involved in the first opening phase described above and corresponding to the still full conveying chamber 4, 5, is opened. A second expulsion phase is then performed wherein the waste in the conveying chamber 4, 5 associated to the closure door 21, 22 opened in the first opening phase, is off-loaded from the holding container 2. The apparatus 1 according to the present invention may be constructed with a single closure door associated to a single outlet opening. In this case, between the first and the second limit position "A", "B", or to coincide thereto, a first and a second emptying position are defined wherein the terminal edge 24 of the orientable portion 14 collimates respectively with a first and a second edge of the outlet opening itself respectively positioned, for instance, in the lower part and in the upper part of the holding container 2. If for instance the operator wants initially to empty the first conveying chamber 4 positioned in the upper part of the collection container 2, the orientable portion 14 is set in the first emptying position, compacting the second waste contained in the second conveying chamber located at the bottom. Subsequently the closure door is opened and the first waste is expelled with the aid of the respective expulsion bulkhead 29a. After the first conveying chamber 4 is emptied, the motor vehicle 6 is driven to the location set to receive the second waste, wherein the position of the orientable portion 14 of the dividing baffle 3 is switched from the first to the second emptying position. Subsequently, the closure door is opened again and the second waste is expelled from the collection container 2 through the outlet opening by means of the respective expulsion bulkhead 29b. If the operator decides initially to empty the second conveying chamber 5, the emptying cycle of the conveying chambers just described is performed inversely. The present invention thereby attains the proposed aims. The invention has the advantages of allowing to empty first indifferently one or the other conveying chamber 4, 5, depending on needs. The apparatus according to the present invention further allows to adapt in a timely manner the internal volume distribution of the collection container 2 according to the quantities of one or the other waste as the waste itself is collected. A considerable increase in the operative flexibility of the motor vehicle intended for rubbish collection is thereby attained. Although the present description is referred to the differentiated collection of two types of waste, nothing precludes the possibility of adapting the apparatus to operate on three or more types of waste, setting a suitable number of conveying chambers, of dividing baffles and of outlet openings. Instead of the orientable portion 14, the baffle 3 may be terminally hinged in proximity to the front wall 12 in such a way that the entire dividing baffle, possibly upon the action of the driving means 13, is involved in the displacements aimed at the volume adaptation of the conveying chambers 4, 5
