Definitions

  • the present patent application relates to a device for collecting waste, a device for unloading such a collection device, and a method for emptying a collection device into such an unloading device.
  • devices for collecting waste, or waste collection devices or waste containers that can be emptied via the bottom side are used in residential areas.
  • a lower section of such waste containers is placed in an opening in the ground, so that a large part of the waste containers is hidden from view.
  • this opening is formed by a concrete silo onto which for safety's sake a safety facility is usually placed.
  • containers for the collection of waste have been given an increasingly larger capacity and this continues to be the case. This is mainly achieved by adapting the height of the lower section of the waste container. This is due to the quantity of waste in modern society still increasing and the wish to limit the nuisance to the people living in the neighbourhood by trying to keep the number of emptying events as low as possible.
  • waste containers have one or more flaps, also called leak trays, at the bottom side. These flaps are kept closed by closing mechanisms and can be operated to open at the right moment.
  • a first type of closing mechanism is used in combination with one flap including a bolt.
  • This bolt can be unbolted by an unlocking member located at the trough and pushing against or tapping an unlocking member of the bolt. At that moment, the lid drops open in downward direction.
  • a second type of closing mechanism is used in combination with two or more flaps having an operation mechanism that can be operated by complementary operation members of the crane.
  • Such an operation mechanism for instance comprises the "Kinshofer-type” or mushroom mechanism or eyes/hooks at an upper side of the waste container and has bars or cables passing through the container to the flaps situated at the bottom for keeping the flaps closed during hoisting or unlocking a lock keeping the flaps closed when the container is suspended over the trough.
  • DE 43 36 146 also discloses a waste container.
  • the waste container has a number of sorting containers 2 that are disposed around an axis in the form of sectors.
  • Each of the sorting containers 2 is provided with a flap 6 that is disposed so as to hinge.
  • the refuse collection lorry is provided with a stop 7 for simultaneously opening each of the flaps 6 when the waste container is positioned on the refuse collection lorry, so that waste from the sorting containers is received in the refuse collection lorry.
  • the first type of closing mechanism has the drawback that when emptying such containers the centre of gravity quickly changes position, causing the containers to sway, hang askew and as a consequence rendering them more difficult to handle by the crane of the refuse collection lorry.
  • the flap also needs to be closed again by pushing it against a base, such as the pavement or an upper edge of the refuse collection lorry. It may also occur that the flap is opened in an uncontrolled manner and waste ends up where it is not wanted.
  • the second type of operating mechanism has the drawback that such operating mechanisms take up considerable room on top of the container and inside in the container, as a result of which there is less room for waste.
  • the waste dropping down can also be impeded by the operating mechanism and waste may get caught on such container operating mechanisms, as a result of which the container is not fully emptied.
  • the waste container as known from FR 2 461 664 has the drawback that the jaws are failure prone to dirt which, for instance, jams one of the jaws as a result of which the motion of both jaws is jammed.
  • the waste container as known from FR 2 625 734 has the drawback that the mechanism for opening and locking the jaws is located outside of and at the lateral side of the caisson, as a result of which the mechanism is sensitive to dirt that may jam the operation of the mechanism.
  • a collection device for collecting waste or waste collection device, collection device or container, wherein the collection device comprises:
  • the flaps are configured for being urged into an inactive position by their own weight, in which position they close off the opening, a mechanism for keeping the flaps closed to keep the waste inside the collection device, for instance when the collection device is being hoisted, is not required. In that way, the collection device also has more volume available for storing waste. It also needs less maintenance.
  • the collection device when it is located in the field, does not need to support with its flaps on the base or a so-called filling set in the opening in the ground to keep the flaps closed and in that way keep the waste inside the collection device, as the flaps remain closed of their own accord.
  • This makes it possible to suspend the collection device from an upper side of the opening in the ground, as a result of which a tidier sealing between the collection device and ground level can be obtained.
  • the tidier sealing is safer for users.
  • the collection device can be emptied in a refuse collection lorry. As a mechanism for keeping the flaps closed is not required, the collection device can even be emptied into a refuse collection lorry using a chain and a hook.
  • the other one of the flaps will still be able to move into the open position.
  • the collection device according to the invention can be emptied as yet, despite the fact that only one of the flaps has been moved into the open position.
  • the collection device may comprise means for keeping the flaps in the inactive position, for instance springs, in order to prevent that the flap is pushed open when this is not wanted.
  • the flaps are urged into an inactive position substantially by their own weight, but can also be partly assisted therein by other means such as push-in springs or draw springs.
  • the flaps can be pivoted between their inactive position and their open position.
  • the movable flaps are configured so as to be slidable.
  • each of the flaps comprises a first and a second hinge, wherein the first hinges are arranged at a first lateral side of the lower section and the second hinges are arranged at a second lateral side of the lower section opposite the first lateral side, wherein the first and second hinges are positioned such that the flaps in the inactive position close off the at least one opening by their own weight.
  • the flaps are configured so as to hinge.
  • first and second hinges are situated closer to the middle of the first and second lateral sides, respectively, than to their respective lateral edges.
  • flaps can be used that move towards each other up to the inactive position due to gravity and close the opening at the bottom of the collection device, without features such as weighting at specific parts of the flaps or a specific design of the flaps.
  • each of the flaps preferably are situated closer to the middle of the respective first and second lateral sides, than to respective centres of gravity of the flaps. This refers to lateral distances, parallel to a bottom side of the collection device. This positioning of the hinge relative to the centre of gravity ensures that the flap always tends to move towards the inactive position.
  • the flaps each comprise a base part and first and second arm parts, wherein the first and second arm parts extend from the base part along the first and second lateral sides, respectively, wherein the first and second arm parts connect the base part to the first and second hinges, respectively.
  • arm parts can be configured flat as a result of which the volume of constructional parts of the collection device remains limited. Furthermore, the arms are able to ensure an improved closure between the flap and the lower section in order for waste to have a smaller chance of falling out of the collection device when this is not wanted.
  • the base parts of the flaps are situated next to each other at their respective first base part sides.
  • the flaps are arranged at the lower section so as to move to such an extend that in a fully open position the flaps completely clear the opening at the bottom of the collection device.
  • the base part sides are near or next to respective exterior sides of the lower section.
  • the base parts of the flaps are situated next to each other at respective first base part sides, wherein the flaps each comprise an upright part extending from the base part opposite the first base part sides, wherein in the inactive position the upright parts extend at least partly in the direction of the upper section.
  • These upright parts ensure that the waste falling out of the collection device is facilitated when the flaps are moved into the open position and the collection device is emptied.
  • the upright part also ensures a smaller turning circle of the flaps, as a result of which less room is required in a trough of the refuse collection lorry.
  • the base parts of the flaps together form a horizontal surface at the bottom side of the collection device.
  • An advantage of the horizontal surface that is formed by the base parts is that the horizontal surface can advantageously cooperate with the common commercially available safety systems capable of covering the opening of the concrete silo when the collection device has been removed from the concrete silo.
  • a safety system also called safety floor
  • the safety systems are intended to prevent that a passer-by falls into the concrete silo when the collection device has been removed from the concrete silo, for instance to be emptied.
  • Such a safety system is for instance provided with a frame that is configured to support on the upper edge of the concrete silo, wherein two floor parts have been provided in the frame.
  • the floor parts are movable between a closed position, in which the concrete silo is closed off, and an open position, in which the collection device is placed inside the concrete silo.
  • each of the floor parts is provided with two operation handles, that means that in total four operation handles have been provided.
  • all operation handles need to be operated.
  • the base parts of the flaps form a horizontal surface, the base parts of the flaps are advantageously capable of operating the operation handles during the lowering of the collection device into the concrete silo. Once the operation handles have been operated by the base parts, the floor parts are taken to the open position, wherein the upright parts of the flaps advantageously lead the floor parts into the open position.
  • the flaps comprise upwardly inclined edges at a perimeter of the base part and the upright part, wherein the upwardly inclined edges situated at the first lateral side connect the base parts and upright parts to the first arm part, and the upwardly inclined edges situated at the second lateral side connect the base parts and upright parts to the second arm part.
  • the upwardly inclined edges can advantageously contribute to centring the collection device relative to a trough of a refuse collection lorry and/or to centring the collection device relative to a concrete silo, optionally provided with a safety system described above, in which the collection device or at least its lower section is housed when in use.
  • the flaps each comprise an actuating member for moving the flaps into the open position by means of an unloading device for unloading the device for collecting waste.
  • actuating members that can be configured as protrusions or stops, can be actuated by a means suitable for the purpose, in the trough.
  • a suitable means in the trough is able to stop the actuating members, as a result of which, during lowering the collection device over the trough, the flaps are pushed open by means of the weight of the collection device.
  • the first and second arm parts comprise an actuating member at their exterior sides, wherein each actuating member, at least partly in the direction of the respective hinge of the first and second hinges, extends at an acute angle to the base part or a notional plane defined by it and/or extends from the upright part.
  • Introducing the collection device less deep into the trough of the refuse collection lorry may in addition have the advantage that the risk of waste getting caught between the flaps during closing the flaps is reduced or ideally eliminated.
  • each actuating member may define a rectilinear as well as a curved movement path. This makes it possible to vary both the opening speed of each of the flaps and the arm relative to a respective hinge.
  • the flaps can be pushed open at one side thereof using one actuating member, it is preferred to configure an actuating member on both sides of the flaps.
  • an acute angle must be understood to be an angle between 0 and 90°.
  • the lower section at the first lateral side and the second lateral side comprises a first and a second guide member, respectively, extending in the direction of the upper section.
  • This guide member can be used in cooperation with a complementary guide element in the trough of the refuse collection lorry for guiding the collection device to a correct position over the trough and in addition also lowering it further in the direction of the trough with increased stability and control.
  • the cooperation between the first and second guide members and the complementary guide element provided in the trough of the refuse collection lorry prevents that the collection device makes a tilting motion about an axis that is approximately transverse to the downward direction of the collection device to be emptied. In other words, in this way it is prevented that the collection device becomes imbalanced.
  • the collection device comprises a plurality of suspension members at an upper side of the lower section, wherein the suspension members are configured for carrying the collection device when it is placed in an opening made in the ground.
  • the suspension members are configured for carrying the collection device when it is placed in an opening made in the ground.
  • the collection device In particular in cooperation with the self-closing flaps, it becomes possible to allow the collection device to be suspended.
  • this will not be necessary.
  • an improved sealing can be achieved between the upper side of the collection device and the ground surrounding the opening therein, which does not only have advantages of an aesthetic nature but also improves user safety.
  • the lower section is divided into two compartments for collecting the waste separately, wherein the bottom side comprises two openings for removing collected waste from the respective two compartments, wherein the flaps are configured for in the inactive position closing off a respective opening of the two openings.
  • an unloading device such as a refuse collection lorry
  • the two flaps in the inactive position together ensure the closing off of the single openings at the bottom side of the collection device.
  • an unloading device for unloading the collection device according to the first aspect.
  • the unloading device comprises:
  • This unloading device has the advantage that no mechanisms for opening the flaps need to be used in the trough.
  • the weight of the collection device in cooperation with the means for urging the flaps open together ensure that the flaps are opened.
  • the unloading device also comprises a crane for hoisting the collection device, it is advantageous that the crane does not need to have a mechanism for operating the flap(s) of the collection device, for instance for engaging and tensioning several eyes or operating the mushroom (Kinshofer-type).
  • the means for urging at least one of the two flaps from the inactive position into the open position are situated at an upper side of the trough and are configured for stopping the at least one of the two flaps of the collection device when the collection device is moved with its bottom side in the direction of the trough.
  • the unloading device further comprises guide means for guiding the collection device to an unloading position for unloading the waste into the trough.
  • These guide means preferably are configured for cooperation with the guide strips of the collection device.
  • the unloading device for unloading the collection device is a refuse collection lorry.
  • the refuse collection lorry comprises a hoisting device or crane for lifting the collection device and for moving it to above a trough for emptying the collection device into the trough.
  • the collection device is configured for being placed in an opening made in the ground and the collection device comprises suspension members for suspending the collection device from an upper side of the opening made in the ground, or from an upper side of a safety facility/safety system.
  • the method further comprises placing the collection device back into the opening made in the ground in order for by means of the suspension members suspending the collection device from the upper side of the opening made in the ground.
  • the lower section then extends downward into the opening made in the ground, wherein the base parts of the flaps are situated at a distance from a bottom or base of the opening made in the ground.
  • the lower section 5 comprises flaps 7 and 9. Via arm part 15, the flap 7 is attached to hinge 11 and via arm part 16 to hinge 12. Via arm part 17, the flap 9 is attached to hinge 13 and via arm part 18 to hinge 14.
  • the arm parts 15-18 are configured as flat plates extending along the front side 31 and rear side 33, respectively.
  • the lower section 5 is in this case configured with corner walls 35, 36, 37 and 38, of which respective parts form the sides 31-34.
  • the corner walls 35 and 36 are attached to each other near the middle of side 31.
  • the corner walls 36 and 37, 37 and 38 and 38 and 35 are attached to each other near the middle of side 32, side 33 and side 34, respectively.
  • Alternative embodiments are conceivable, for instance by using plates that are connected to each other near the boundaries between sides 31-34.
  • the advantage of using corner walls 35-38 is that at the attachment locations between corner walls 35 and 36 and 37 and 38 flaps 7 and 9 can also be attached. This ensures reduced use of material and/or a reinforcement of the structure.
  • the lower section 5 has an opening 60 from which the waste can be removed. In the open position of the flaps ( Figures 3 and 4 ) this opening is cleared so that the waste is able to drop out of the collection device.
  • the base parts 61 and 63 comprise edges 62 and 64, respectively, which in the inactive position are situated next to each other or abut each other. Those edges 62 and 64 are an embodiment of the first base part sides.
  • the flaps 7 and 9 further comprise respective upright edges 69 and 71 along a perimeter of the respective base parts 61 and 63 and upright parts 65 and 67.
