Waste compactor integrated into a container

Abstract

The device according to the invention is a CT1 or CT2 compactor that compacts waste to reduce its volume and thus allow for less frequent collection. Two non-extensible and non-retractable flexible components, RC1 and RC2, each travel within a housing, LG1 and LG2, along a trajectory such that the thrust of a geared motor MT, associated with a screw V and a nut EC captive in a longitudinal profile SHS, causes said components RC1 and RC2 to slide. At their ends opposite SHS, they are connected to a piston PT1 or PT2, which compacts the waste contained in a container BA or BB.

[0005] Previous achievements do not allow for deployment to meet the needs of municipalities due to their significant cost.

[0006] The device according to the invention attempts to overcome these drawbacks while offering a product with simple implementation and a competitive price.

[0007] The compactor according to the invention is designed to be able to be integrated into several sizes of containers intended for various types of waste such as household waste and cardboard packaging.

[0008] The device according to the invention is a compaction device intended to reduce the volume of waste contained in a bin, bin enclosed in a container comprising a lower part called a casing which has an access door to the bin containing the waste, container comprising an upper part which has power supply means in the form of a solar panel and electrical storage in a battery of accumulators, electronic management means, a waste disposal hatch provided with a motorized cover, compaction device characterized in that it has means for maintaining its position in the container, differentiated disposal means in the container according to the nature of the waste, means for transmitting movement capable of driving at least one non-extensible and non-retractable flexible element contained and circulating in a housing along a predefined trajectory,housing which has at least one straight vertical part disposed outside the bin, itself followed by at least one curved part which ends in a straight vertical part which enters the bin by means of an extension / retraction means which in its extension cycle generates a compaction of the waste contained in the bin by means of a compaction device, compaction device, which also has security measures in place to prevent the dumping of waste during the compaction operation.

[0009] Device characterized in that the non-extensible and non-retractable flexible element is a steel spring with contiguous coils called an endless tension spring inside which is crimped on each of the two ends of said spring a cable which constrains its extension and in that the section of the wire of the spring associated with its diameter allows longitudinal maintenance without bending or camber of said spring if it is held in position by a guiding means arranged vertically at intervals of less than 10cm, sometimes 15cm or even up to 20cm when said spring must oppose a maximum compaction thrust.

[0010] Device characterized in that the means of transmitting the motion consist of a geared motor associated with a screw / nut mechanism connected directly or via a part provided for this purpose with one end of at least one non-extensible flexible element which travels in the housing provided for this purpose to terminate by a connection with a piston, such an arrangement generates a vertical translational displacement of said non-extensible flexible element substantially of the same distance as the vertical translational displacement of the nut along the screw in order to allow the piston to compress the waste contained in the bin.

[0011] Device characterized in that the extension or retraction means is composed of several scissor arms articulated together, thus forming at least one retractable or extendable triangulated ladder in a vertical plane, triangulated ladder having means for maintaining its position in the upper part with a structure fixed on the curved portion of the housing of the non-extendable flexible element and in the lower part by a connection with the piston, each median articulation of scissor arms composing the at least one triangulated ladder being provided with a vertically arranged cylindrical sub-assembly whose axis is substantially coincident with the vertical axis of the non-extendable and non-retractable flexible element, cylindrical sub-assembly provided with a position retention which allows a vertical translation,cylindrical subassembly whose internal cross-section is greater than the cross-section of the non-extensible and non-retractable flexible element such that each cylinder can be traversed and thus guide said non-extensible and non-retractable flexible element during the extension of at least one triangulated ladder, the distance between two directly opposite cylinders always being less than the distance that could cause deflection of the non-extensible and non-retractable flexible element when the ladder is stretched to the maximum and the power is also at its maximum to allow the piston to compact the waste.

[0012] Device characterized according to a first preferred embodiment in that the means for the differentiated disposal of waste is carried out in the upper part of a container CTI by the position of a TRI hatch which is arranged directly opposite and above a piston PT1 which has on its horizontal base a machined part PU which leaves a space which is closed by two pivoting openings, OH1 and OH2, each articulated on an opposite side of the machined part PU, such that these openings OH1 and OH2 come into contact with the lower part of a funnel N arranged under the TRI hatch for depositing waste from the CTI container when the piston PT1 reaches the upper position, this contact causes the openings OH1 and OH2 to pivot towards the bottom of the BA bin, which allows the waste to pass first into the TRI hatch and then through the orifice opened by the pivoting of the openings OH1 and OH2, the waste thus deposited passes through the piston PT1 without any obstruction to fall by gravity into the bin.

[0013] Device characterized according to a first preferred embodiment in that as soon as the openings OH1 and OH2 are no longer in contact with the funnel N, i.e. when the piston PT1 is directed towards the bottom of the container BA under the effect of the translation of the non-extensible and non-retractable flexible element, the openings OH1 and OH2 return to a substantially horizontal position under the action of the springs OR1 and OR2, which completely closes the machined part PU and thus allows the compaction of the waste by the piston PT1.

[0014] Device characterized according to a first embodiment in that the opening of the hatch is motorized, the opening action of the hatch is electrically blocked for the entire duration of the compaction in order to avoid any risk of accident related to the depositing of waste.

[0015] Device characterized in that the compactor is designed as a single unit and has means for maintaining its position in the container at least in the upper part of said container so that it can be placed in a container not intended for this use during its installation.

[0016] Device characterized according to a second preferred embodiment in that the means for the differentiated deposit of waste is carried out in a hatch TR2 arranged vertically in the upper part of a container CT2, hatch TR2 located between a piston PT2 and a bin BB, outside the upper horizontal surface of the bin B, hatch TR2 whose width is at least twice greater than its height, hatch TR2 provided with a cover CV2 immediately disposed inside the hatch TR2, cover CV2 which in the open position is arranged angularly in order to serve as a guide for the waste in the bin BB, cover CV2 which closes to seal the hatch TR2 as soon as a compaction order is issued in order to prohibit deposits during compaction.

[0017] Device characterized according to a second preferred embodiment when the piston PT2 has finished compacting and has returned to its waiting position, The CV2 cover opens and positions itself in standby mode until the next compaction, allowing deposits to be made again.

[0019] The device according to the invention is a waste compactor intended to be installed in a waste container of the shelter-bin type, the compactor whose function is to reduce the volume of waste contained in a bin and thus minimize the frequency of collections for economic and ecological reasons.

[0020] The device according to the invention is a compactor intended to be integrated into a container.

[0021] We will distinguish here two types of containers, a CTI container intended to receive waste of the household waste type and a CT2 container intended to receive waste of the packaging type, in particular cardboard.

[0022] Indeed, the adaptation of the compactor and certain technical characteristics are different depending on the type of container.

[0023] The two types of containers have in common a metal box CN1, CN2 in the lower part, a metal box equipped with an access door P, PP allowing the collection of waste contained in a bin BA, BB.

[0024] The upper part of both types of containers includes a solar panel and battery power supply, a waste disposal hatch sealed by a motorized CV1, CV2 cover including mechanical locking means.

[0025] We describe below the compactor part before giving two examples of preferred embodiments concerning the two adaptation variants according to one or the other type of container.

[0026] The compactor has means for maintaining its position in the metal box CN1 or CN2, a plurality of metal profiles connected together form a framework OS which maintains the transmission elements of the movement of the compactor C as well as the position of said compactor C on an upper perimeter frame of the box CN1 or CN2.

[0027] Fixing these metal profiles to said perimeter frame allows the compactor C to be positioned and stiffened on the CN1 or CN2 box.

[0028] This OS framework positions and clamps in the CN1 or CN2 box two vertical longitudinal profiles PLI, PL2 spaced apart from each other which surround a geared motor MT coupled to a screw V which receives a nut EC captive of a horizontal longitudinal profile PLH.

[0029] Each of the two ends of the PLH profile enters respectively into the PLI profile for one and PL2 for the other by means of a vertical longitudinal slot made in each of the two PLI and PL2 profiles.

[0030] The captive nut EC is disposed substantially at the horizontal longitudinal center of the PLH profile.

[0031] The internal section of the two profiles PLI and PL2 is identical, and substantially square in shape.

[0032] The width of the slot made in the PLI and PL2 profiles is less than the inner width of the side of said PLI or PL2 profiles so that each PLI and PL2 profile can hold in position, a non-extensible and non-retractable flexible element in the form of an identical cylindrical spring / cable RC1 and RC2.

[0033] The cylindrical section of RC1 or RC2 is less than the internal section of the PLI or PL2 profiles.

[0034] The diameter of the spring RC1 or RC2 is greater than the width of the slot made in the identical profiles PLI and PL2.

[0035] The diameter of the spring RC1 or RC2 is less than the length of the side of the inner square of the section of the profiles PLI or PL2.

[0036] The PLI and PL2 profiles serve as housing for the RC1 and RC2 springs / cables respectively.

[0037] Each end of the PLH profile is secured with one of the two ends of the cable springs RC1 and RC2.

[0038] As a result, the vertical translational displacement of the nut EC on the screw V driven by the geared motor MT de facto causes a vertical translational displacement of the same amplitude and in the same direction as the springs / cable RC1 and RC2.

[0039] The PLI and PL2 profiles and the assembly including the geared motor MT, the screw V, the nut EC captive in the PLH profile are arranged in a vertical plane parallel and close to the vertical wall forming the bottom of the box, opposite the door P providing access to the BA tray, and outside said BA tray.

[0040] The PLI and PL2 profiles are continued and coupled each in a vertical plane perpendicular to the vertical plane of the wall forming the bottom of the box and in the upper part of the box CN1 or CN2, coupled each respectively to an API and AP2 arrangement of profiles forming between them a curved housing LG1, LG2 intended to receive and guide each respectively the cable spring RC1 and RC2.

[0041] API and AP2 are two identical arrangements.

[0042] We will describe the API layout as an example.

[0043] API consists of two longitudinal profiles PL3 and PL4 arranged in the same vertical plane.

[0044] Longitudinal profiles PL3 and PL4 are sandwiched between two vertical longitudinal plates PL5 and PL6 intended to secure the profiles PL3 and PL4 to each other and to the OS framework.

[0045] The upper curved longitudinal slice of PL4 is opposite the lower curved slice of PL3, slices separated by a space slightly greater than the outer diameter of the cable spring RC1 or RC2.

[0046] The opposite slices of PL3 and PL4 are of the same thickness.

[0047] This thickness is designed to be slightly greater than the diameter of the spring / cable RC1 or RC2 in order to allow the spring / cable RC1 or RC2 to be held and slid within an LG housing whose internal walls are:

[0048] - the upper slice of PL4,

[0049] - the lower slice of PL3,

[0050] - the faces opposite the spring / cable RC1 of the plates PL5 and PL6

[0051] In the interest of saving material, the thickness of PL3 and PL4 can be reduced by compensating with thickness shims, as long as the distance between the inner walls of the profiles PL5 and PL6 is always greater than the diameter of the spring / cable RC1 or RC2.

[0052] The curved housing of each spring / cable RC1 or RC2 materialized in the identical arrangements API and AP2, namely the housing LG1 described above and the identical housing LG2 are respectively in the extension of the longitudinal vertical housing of each spring cable RC1 and RC2 materialized by the profiles PLI and PL2.

[0053] Housings LG1 and LG2 are arranged in the rear part of the BA tray as an extension of the PLI and PL2 profiles to continue above the BA tray.

[0054] The AGI and AG2 arrangements have means for maintaining their position on the OS framework.

[0055] A structure SHS which forms a horizontal rectangle whose vertical walls leave a free surface S is inscribed above the tray BA and fixed on the frame OS.

[0056] The AGI and AG2 arrangements are each fixed on a vertical side SI for AGI and S2 for AG2 of the SHS structure.

[0057] Sides SI and S2 are identical, parallel and distant from each other, they border the surface S on two opposite vertical sides.

[0058] Two retractable / extendable triangulated ladders EX1 and EX2 are arranged respectively on side SI for EX and on side S2 for EX2.

[0059] Since the connection of the two ladders EX1, EX2, as well as their respective movement of retraction or extension, is identical and simultaneous, we will describe here only the ladder EX1

[0060] The triangulated ladder EX1 has several longitudinal scissor arms articulated together at their midpoint and at each end, ladder EX1 arranged in a vertical plane PL. These arms, identical to each other, form a pair of scissor arms identified herein as BAI and BA2. Only the scissor arms forming the two ends of the triangulated ladders EX1 and EX2 differ in shape, primarily to minimize the height required to achieve good vertical guidance of said ladders.

[0061] The upper end of the ladder EX1 consists of two scissor arms BH1 and BH2 articulated to each other along their respective longitudinal lengths, the free end of each of the two arms BH1 and BH2 being articulated with a horizontal slot LH formed in the side SL

[0062] The articulation of BH1 with BH2 runs within a vertical slot LV formed in the SI side of SHS. The articulation of the free ends of BH1 and BH2 in the horizontal slot LH, linked to the central articulation of BH1 with BH2 in the vertical slot LV, ensures vertical guidance of the EXL ladder.

[0063] The same applies to the EX2 scale on the S2 side.

[0064] To minimize the height of the LV light when the EX1 ladder is deployed, the articulation of BH with BH2 is arranged closer to the articulated ends in the horizontal LH light.

[0065] Thus guided, the EX1 ladder can be extended or retracted vertically in the PI plane if the scissor arms forming its lower base are subjected to a vertical pressure in the PI plane in one direction or the other.

[0066] Each central articulated link of a pair of scissor arms of the EX1 ladder is provided with a cylindrical device AC, with vertical axis AVX, cylindrical device AC whose height must always be less than the center distance between two opposing central joints when the EX1 ladder is completely retracted.

[0067] The AVX axis is substantially coincident with the articulation axis of the cable spring RC1 at the point where it exits the curved part located above the BA tray.

[0068] The extension of the EX1 ladder causes the cylindrical apparatus AC to shift by means of a cylindrical apparatus AC bis, identical to AC, AC bis being disposed on the central articulation of the pair of scissors BA1 bis and BA2 bis, identical to BAI and BA2 immediately opposite and connected with BAI and BA2, AC bis having the same vertical axis AVX as AC.

[0069] Each pair of scissors forming the ladder EX1 is thus provided with a cylindrical apparatus identical to AC in order to guide the spring / cable RC1 vertically in the tray BA.

[0070] The extension of the EX1 ladder causes the cylindrical apparatus AC to move away from each other from the cylindrical apparatus AC bis and in the same way all the other pairs of scissors forming the EX1 ladder.

[0071] The RC1 cable spring is thus guided in each cylindrical device of type AC to be articulated by its free end on a horizontal base called piston.

[0072] The same applies to the identical spring / cable RC2.

[0073] The springs / cables RC1 and RC2 described above circulate identically in one direction or the other, each respectively along an identical trajectory TA1 and TA2, parallel to each other, springs / cables RC1 and RC2 being driven by the thrust of the geared motor MT and the screw V and nut EC couple in their respective housing, namely for RC1:

[0074] -the PLI profile,

[0075] -T AGI layout

[0076] - the multiplicity of identical cylindrical devices to AC articulated on the ladder XL

[0077] For RC2:

[0078] - The PL2 profile

[0079] - The AG2 arrangement

[0080] - The multiplicity of identical cylindrical devices to AC articulated on the ladder EX2.

[0081] The two scales EX1 and EX2 are articulated on the piston at their respective free lower ends.

[0082] For both the EX1 and EX2 scales, the articulation on the piston is made between the free ends of the pair of scissors in the lower part, the two end axes of which are articulated in at least one horizontal slot made on a vertical side VC1 of the piston for the EX1 scale and a vertical side VC2, parallel to VC1 for the EX2 scale.

[0083] When the EX1 scale is fully extended, the piston is lowered to the maximum in the BA or BB tray, the vertical distance DV between two cylindrical devices AC and AC bis opposite each other and with the same axis must always be less than 20 cm, sometimes 15 cm, and most often less than 10 cm.

[0084] When the nut EC is positioned at the vertical end opposite the geared motor MT on the screw V, the rotation of the geared motor MT in the direction that allows the nut EC to approach the geared motor MT simultaneously generates: • A vertical translation of the longitudinal horizontal profile PLH in the direction of the geared motor MT, • A vertical translation of the portion of the springs / cables RC1 and RC2 contained within the longitudinal vertical profiles PLI and PL2, of the portion of the springs / cables RC1 and RC2 contained in the arrangements AC1 and AC2 of the curved part, of the part of the springs / cables RC1 and RC2 guided in the cylindrical devices identical to AC and AC bis towards the bottom of the BA tank, a vertical translation of the piston towards the bottom of the BA tank, a translation whose height is substantially the same as the height of the displacement of the nut EC on the screw V.

[0085] When the nut EC is positioned at the vertical end near the geared motor MT on the screw V, the rotation of the geared motor MT in the direction that allows the nut EC to move away from the geared motor MT simultaneously generates: • A vertical translation of the longitudinal horizontal profile PLH in the opposite direction to the geared motor MT, a vertical translation of the part of the springs / cables RC1 and RC2 contained in the longitudinal vertical profiles PLI and PL2 in the opposite direction to the geared motor MT, of the part of the springs / cables RC1 and RC2 contained in the arrangements AC1 and AC2 of the curved part, of the part of the springs / cables RC1 and RC2 guided in the cylindrical devices identical to AC and AC bis towards the top of the tray BA, a vertical translation of the piston towards the top of the tray BA, a translation whose height is substantially the same as the height of the displacement in opposite translation of the nut EC on the screw V.

[0086] In the fully retracted position, the piston is immobilized high above the bin, a position which allows an authorized person to collect the waste contained in said bin.

[0087] We have described above the compactor in its compaction function as well as its adaptation in a waste container without taking into account the problem of waste deposit and its interaction with the compactor device depending on the type of container.

[0088] As indicated in the preamble to this description, the containers which allow integration of the device according to the invention are provided with motorized waste disposal lids.

[0089] The device according to the invention is mainly intended to be integrated into waste containers for household waste as well as into containers that receive cardboard mainly from packaging.

[0090] According to a first preferential embodiment, the CTI container is a bin shelter for household waste whose motorized cover CV1 and the TRI waste deposit hatch are located in the upper part of the CTI container above and vertically opposite the BA bin.

[0091] In this configuration, the CV1 cover covers a waste disposal hatch which is bordered by a funnel N whose oblique walls are directed towards the inside of the B A container.

[0092] A piston PT1 has a horizontal central part PU machined with an orifice located opposite the lower part of the funnel N, the surface area of ​​which is at least equal to that of the smallest horizontal section of the funnel N.

[0093] This central part is provided and sealed with at least one horizontal opening in the closed position.

[0094] For reasons of space, at least one opening is represented here by way of example by two openings OH1 and OH2 articulated, each on an opposite side of the machined central part PU.

[0095] The opening of the two openings OH1, OH2 is directed towards the bottom of the tray B A.

[0096] The horizontal retention of the openings OH1 and OH2 is ensured by at least one spring OR1 for OH1 and at least one spring OR2 for OH2.

[0097] During the complete ascent of the piston PT1, the openings OH1 and OH2 come into contact with the lower part of the funnel N, and more precisely with the sides of the funnel N opposite the openings OH1 and OH2.

[0098] This contact causes an opening of said openings which thus release the central part PU.

[0099] This release of the central PU part allows the deposit of waste which passes through the funnel N then through the piston PT1 through the PU part opened by the pivoting of the openings OH1 and OH2 before ending up in the tray B A.

[0100] When compaction is programmed by a cyclic programming means or triggered by a filling probe, the CV1 cover is mechanically and electronically locked to prevent any deposition during compaction.

[0101] The compaction function described above causes the piston PT1 to move towards the bottom of the tank.

[0102] This movement eliminates the contact of the sides of the funnel N with the openings OH1 and OH2 which close under the action of the springs OR1 and OR2.

[0103] This configuration where the PU part is sealed allows the compaction of the waste contained in the BA container.

[0104] According to a second preferred embodiment, the CT2 container is a bin shelter for household waste, the motorized cover of which CV2 is located in the upper part on the front of said CT2 container, also on the front and outside the horizontal reception surface of the BB bin.

[0105] The TR2 waste disposal hatch is arranged substantially vertically so that the waste is introduced horizontally into said hatch and then falls into the BA bin by gravity.

[0106] A waste guide plate in the bin is arranged inside the TR2 hatch to prevent part of the deposit from ending up outside the BB bin.

[0107] When compaction is programmed by a cyclic programming means or triggered by a filling probe, the CV2 cover is mechanically and electronically locked in the closed position to prevent any deposition during compaction.

[0108] The compaction function described above causes the PT2 piston to move towards the bottom of the BB container, the PT2 piston then moves back up above the BB container to be immobilized and allow the motorized cover CV2 to be opened again to permit the removals.

[0109] The first preferred embodiment differs from the second preferred embodiment in that the cover CV1, the trapdoor TRI and the funnel N are arranged directly opposite each other vertically above the piston PT1, whereas the cover CV2 and the trapdoor TR2 are located between the tray BB and the piston PT2, vertically outside the horizontal receiving surface of the tray BB.

[0110] These structural differences are explained by the nature of the waste deposited.

[0111] In the case of household waste, this mainly consists of leftover food and its packaging deposited in the city by residents and tourists.

[0112] The CTI container is called a bin shelter or city bin. The TRI hatch is most often a square measuring 300 x 300mm.

[0113] In the case of the CT2 container for packaging, it mainly involves deposits of cartons which require a horizontal TR2 hatch with a width that can go up to or even exceed 1000mm and a low height of 50 to 150mm.

[0114] This low height makes it possible to restrict the size of cardboard packaging deposited by thus recommending that the depositor fold the largest cartons.

[0115] We have thus produced a device in accordance with the invention.

[0116] Of course, the invention is by no means limited to the embodiment described and represented, which has been given only by way of example.

[0117] The invention includes all technical equivalents of the means described and their combinations, if these are executed in accordance with its spirit and implemented within the scope of the following claims.

Device according to claims 1, 4 and 5 characterized always according to a first preferred embodiment in that as soon as the openings (OH1) and (OH2) are no longer in contact with the funnel (N), i.e. when the piston (PT1) is directed towards the bottom of the container (BA) under the effect of the translation of the non-extensible and non-retractable flexible member, the openings (OH1) and (OH2) return to a substantially horizontal position under the action of the springs (OR1) and (OR2), which completely closes the machined part (PU) and thus allows the compaction of the waste by the piston (PT1).

7. Device according to claims 1, 4, 5 and 6 characterized according to a first embodiment in that the opening of the hatch is motorized, the opening action of the hatch is electrically blocked for the entire duration of the compaction in order to avoid any risk of accident related to the depositing of waste.

8. Device according to claim 1 characterized in that the compactor is designed as a single unit and has means for maintaining its position in the container at least in the upper part of said container so that it can be placed in a container not intended for this use during its installation.

9. Device according to claims 1 and 4 characterized in a second preferred embodiment in that the means for the differentiated disposal of waste is carried out in a hatch (TR2) disposed vertically in the upper part of a container (CT2), hatch (TR2) located between a piston (PT2) and a bin (BB), outside the upper horizontal surface of the bin (B), hatch (TR2) having a width of at least twice its height, hatch (TR2) provided with a cover (CV2) immediately disposed inside the hatch (TR2), cover (CV2) which in open position is angled to serve as a guide for waste into the bin (BB), cover (CV2) which closes to seal the hatch (TR2) as soon as a compaction order is issued in order to prohibit deposits during compaction.

10. Device according to claims 1, 4 and 9 characterized according to a second preferred embodiment whereby when the piston (PT2) has finished compacting and has returned to its standby position, the cover (CV2) opens and positions itself in standby until the next compaction allowing the removals again.
