[0001] 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.
[0002] 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 12.
[0003] 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.
[0004] 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.
[0005] 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.
[0006] 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.
[0007] 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.
[0008] 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.
[0009] 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.
[0010] 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.
[0011] 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.
[0012] 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.
[0013] 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.
[0014] 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.
[0015] 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.
[0016] 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.
[0017] 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.
[0018] 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.
[0019] 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.
[0020] 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
12.
[0021] 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.
[0022] 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.
[0023] 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.
[0024] 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.
[0025] 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.
[0026] 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.
[0027] 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.
[0028] 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.
[0029] 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.
[0030] 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.
[0031] 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.
[0032] 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.
[0033] 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.
[0034] 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.
[0035] 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".
[0036] 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.
[0037] The second door 22 is entirely shaped according to an arched profile, and it is oscillatorily
hinged below the transverse bar 23.
[0038] 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.
[0039] 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.
[0040] In accordance with the storing method according to the invention, the operation of
the subject apparatus 1 is the following.
[0041] 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.
[0042] 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.
[0043] 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.
[0044] 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.
[0045] 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.
[0046] 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.
[0047] 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.
[0048] 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.
[0049] 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.
[0050] 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.
[0051] 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.
[0052] 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.
[0053] 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.
[0054] 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.
[0055] 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.
[0056] 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".
[0057] 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.
[0058] 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.
[0059] 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.
[0060] The apparatus 1 according to the present invention may be constructed with a single
closure door associated to a single outlet opening.
[0061] 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.
[0062] 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.
[0063] 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.
[0064] If the operator decides initially to empty the second conveying chamber 5, the emptying
cycle of the conveying chambers just described is performed inversely.
[0065] The present invention thereby attains the proposed aims.
[0066] The invention has the advantages of allowing to empty first indifferently one or
the other conveying chamber 4, 5, depending on needs.
[0067] 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.
[0068] 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.
[0069] 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
