Description

FIELD

The improvements generally relate to the field of waste collecting devices and more specifically to systems and methods used to compact waste and to unload waste containers.

BACKGROUND

Existing waste collecting devices typically have a container and a hydraulic piston that is used to lift the container at an angle relative to the ground. In such devices, the wastes flow out of the container with gravity. These devices may be unsuitable in waste facilities having a low-height ceiling. Moreover, lifting the container might be dangerous because the center of gravity of the container is raised at a high level above ground. This impairs the stability of a vehicle carrying the container. Moreover, hydraulic systems are very expensive, energy consuming, and might be prone to failure in low temperature operating conditions. Hence, improvements are possible.

DETAILED DESCRIPTION

Referring to FIGS. 1-6, a waste collecting device in accordance with an embodiment is shown at 10. The waste collecting device 10 is configured to be used mounted on a vehicle. The device 10 includes a container 12 for receiving waste. The container 12 extends between a first end 12a and a second end 12b spaced apart from the first end 12a along a longitudinal axis L of the container 12. Herein below, the first and second ends are referred to as front and rear ends 12a, 12b for clarity. It is however understood that the front and rear ends 12a, 12b may be reversed relative to a direction of travel of a vehicle having the device 10 mounted thereon without departing from the scope of the present disclosure.

The container 12 has a first end wall 14 located at the front end 12a and a second end wall 16 located at the rear end 12b. The container 12 further has side walls 18 extending along the longitudinal axis L from the front end 12a wall to the second end 12b. The side walls 18 include two lateral walls 18a, a ceiling 18b, and a floor 18c. As shown, the walls 14, 16, 18 of the container 12 encloses a waste receiving volume V. In the embodiment shown, a waste opening 20 is defined through the first end wall 14 for allowing access to the waste receiving volume V. The waste, when collected, is inserted in the waste receiving volume V of the container 12 via the waste opening 20. In the embodiment shown, the waste opening has an area of about one square meter.

To maximize a quantity of waste contained within the container 12 and to push the waste in the container 12, the waste collecting device 10 is equipped with a compactor 22. The compactor 22 is located at the front end 12a and is operable to push the waste in the container 12 via the waste opening 20. The compactor 22 is configured to exert a force on the waste such as to increase a density of the waste contained within the container 12. In the embodiment shown, the compactor 22 is located outside the waste receiving volume V and is located adjacent the waste opening 20 defined through the first end wall 14 so that the compactor 22 has access to the waste opening 20 and hence to the waste receiving volume V of the container 12.

In the embodiment shown, the compactor 22 is a screw conveyor including a screw 22a (FIG. 3) in driving engagement with a first motor 24, which may be electric or hydraulic. In operation, the screw 22a rotates about a rotation axis R. The waste is then received between threads of the screw 22a and, when the screw 22a is in rotation, the threads carry the waste in a direction parallel to the rotation axis R. In the embodiment shown, the rotation axis R of the screw 22a is parallel to the longitudinal axis L of the container 12. A gearbox/reductor may be used to increase a torque of the first motor 24 to increase a compaction ratio of the compactor 22. It is understood that the compactor 22 may be provided in the form of a piston engaged by hydraulic actuator(s); the piston having a reciprocating movement that may be parallel to the longitudinal axis L for pushing the waste through the opening 20.

Referring more particularly to FIGS. 1-2, the waste collecting device 10 further includes a hopper 26 that is located above the compactor 22. The hopper 26 may be secured to the container 12. The hopper 26 defines a waste receiving area 26a that is greater than a diameter of the screw 22a. Therefore, the hopper 26 temporarily holds the waste before it reaches the compactor 22 to be pushed thereby through the waste opening 20. Stated otherwise, the hopper 26 guides the waste toward the compactor 22 for subsequent compaction.

In the embodiment shown, the waste collecting device 10 further includes an enclosure 28 that may be affixed to the hopper 26 and/or to the first end wall 14. The enclosure 28 is located above the hopper 26 and the compactor 22. In the illustrated embodiment, the enclosure 28 is configured to allow access to the compactor 22 solely via an opening 28a located on a side thereof. Hence, the enclosure 28 might preclude waste from falling out of the hopper 26 when the waste is thrown toward the compactor 22. The enclosure 28 might also allow access to the compactor 22 solely to an operator of the waste collecting device 10 for security purposes.

Referring more particularly to FIG. 4, the second end wall 16 of the container 12 is a door 30 that is pivotally mounted to a remainder of the container 12 and that is used for closing a discharging opening 12c of the container 12. More specifically, the door 30 is pivotally mounted to a rear edge of the ceiling 18b of the container 12. In the depicted embodiment, the door 30 rotates about an axis of rotation that is perpendicular to the longitudinal axis L and perpendicular to the lateral walls 18a The door 30 may be actuated using, for instance, hydraulic or electric actuators 32, or any suitable mechanism known in the art. The door 30 is pivotable between a closed position and an opened position. In the opened position, the door 30 allows access to the waste receiving volume V for emptying the container 12. When filling the container 12, the door 30 is usually in the closed position so that the waste is retained within the container 12.

Referring more particularly to FIGS. 4-6, the waste collecting device 10 further includes an ejector panel 34 for pushing the waste out of the container 12. The ejector panel 34 has a waste opening 34a (FIG. 5) defined therethrough that registers with the waste opening 20 defined through the first end wall 14. The registering waste openings 20, 34a of the first end wall 14 and of the ejector panel 34 allow the waste to be inserted in the waste receiving volume V of the container 12 through both the first end wall 14 and the ejector panel 34. The ejector panel 34 is movable along the longitudinal axis L between the front and rear ends 12a, 12b and relative to the floor 18c of the container 12. This movement of the ejector panel 34 pushes the waste toward the discharging opening 12c of the container 12 and out of the waste receiving volume V via said opening 12c. It is understood that the ejector panel 34 and the first end wall 14 may be a sole entity that is entirely movable along the longitudinal axis L.

In the embodiment shown, a footprint area of the ejector panel 34 corresponds substantially to an internal cross-sectional area of the container 12 taken perpendicularly to the longitudinal axis L. The footprint area might be slightly less than the internal cross-sectional area to allow the ejector panel 34 to move between the first and second ends 12a, 12b without contacting the side walls 18. In a particular embodiment, having the ejector panel 34 covering almost an entirety of the internal cross-sectional area allows all the waste to be pushed out of the container 12 in a unique pass, without requiring a plurality of passes of the ejector panel 34 within the container 12. Moreover, by being dimensioned as shown, the ejector panel 34 might prelude waste from escaping behind the panel 34 via gaps between edges of the ejector panel and the side walls 18.

In the embodiment shown, the first end wall 14 and the ejector panel 34 define conjointly a cylindrical conduit 36 that connects the waste openings 20, 34a of the first end wall 14 and of the ejector panel 34. In the embodiment illustrated, the compactor screw 22a extends through the cylindrical conduit 36, which contributes in guiding the waste toward the waste receiving volume V. The conduit 36 might preclude waste from falling between the first end wall 14 and the ejector panel 34.

Referring now more particularly to FIGS. 5-6, the floor 18c of the container 12 has rails 38 affixed thereto and that are used for guiding the ejector panel 34 along its course between the front and rear ends 12a, 12b. The rails 38 are configured to be engaged by corresponding elements of the ejector panel, which are tabs 40 in the embodiment shown. Roller bearings may be disposed between the tabs 40 and the rails 38 to ease the translational movement of the ejector panel 34. Other configurations are contemplated. It is understood that the rails 38 may be located at other locations, for instance, on the lateral walls 18a between the floor 18c and the ceiling 18b, or secured to the ceiling 18b.

The waste collecting device 10 includes a second motor 42, which may be electric or hydraulic, for inducing movement of the ejector panel 34. In the embodiment shown, the second motor 42 is secured to the ejector panel 34 below the waste opening 20 and is in driving engagement with the rails 38. More specifically, the second motor 42 transmits its rotational input to gears 44 (FIG. 6) that are in a mating engagement with apertures 46 (FIG. 3) defined through the rails 38. Such an engagement causes the ejector panel 34 and the second motor 42 secured thereto to move relative to the rails 38 of the floor 18c toward the second end wall 16. The gears 44 may be either directly engaged by the second motor 42 or via a gear box or any suitable transmission mechanism known in the art. Therefore, actuation of the second motor 42 induces rotation of the gears 44 that engage the rails 38. It is understood that any suitable mechanism that may be used to move the ejector panel 34 along the longitudinal axis L without departing from the scope of the present disclosure. In the embodiment shown, the compactor 22 remains substantially immobile relative to the floor 18c when the ejector panel 34 moves for emptying the container 12.

The waste opening 34a of the ejector panel 34 is preferably blocked when emptying the container 12 to avoid waste from falling in a space located axially between the first end wall 14 and the ejector panel 34. If that would occur, it might preclude the ejector panel 34 from going back to its original position. Therefore, the waste collecting device 10 includes a blocking device 50. In the depicted embodiment, the blocking device 50 is affixed to the ejector panel 34 and includes two stems 52 that may be actuated by, for instance, hydraulic or electric actuators (not shown). In use, the blocking device 50 is operable to move the stems 52 in a direction perpendicular to a central axis C of the waste openings 20, 34a and from a first position in which the stems 52 extend through the waste openings 20, 34a and a second position in which the stems 52 are offset from the waste openings 20, 34a. Stated otherwise, in the second position of the stems 52, the stems 52 do not offer resistance to the waste circulating within the cylindrical conduit 36. In the first position, the stems 52 extend through the cylindrical conduit 36.

Referring now to FIGS. 7-8, a vehicle for collecting waste is shown at 100. The vehicle 100 includes a frame 100a, wheels 100b rotatably mounted to the frame 100a, and a waste collecting device 102 that is secured to the frame 100a. For the sake of conciseness, only elements that differ from the waste collecting device 10 of FIGS. 1-6 are described herein below.

In the embodiment shown, a container 112 includes two halves: an upper halve 112a and a lower halve 112b. The upper halve 112a includes a first end wall 114, a second end wall 116, a ceiling 118b, and an upper section 118a₁ of each of lateral walls 118a. The lower halve 112b is substantially immobile relative to the frame 100a and includes a lower section 118a₂ of each of the lateral walls 118 and a floor 118c. The upper halve 112a is movable relative to the lower halve 112b along the longitudinal axis L.

In the embodiment shown, the compactor 22 is secured to the first end wall 114, which corresponds, in this embodiment, to an ejector panel 134. The compactor 22 moves with the first end wall 114 and the upper halve 112a. More specifically, the compactor 22 is secured to a lower portion of the first end wall 114. As shown, the screw 22a remains within the cylindrical conduit 36 of the first end wall 114 when the upper halve 112a moves. Hence, in the embodiment shown, the blocking device that precludes the waste from falling behind the first end wall 114 corresponds to the screw 22a of the compactor 22. Hence, the stems and the actuators that drives them are not required for the waste collecting device of this embodiment.

The upper halve 112a and the lower halve 112b define a sliding interface 112c therebetween. The sliding interface 112c is located along adjacent edges of the upper and lower sections 118a₁, 118a₂ of the lateral walls 118. Roller bearings may be disposed within the sliding interface 112c between said edges for easing a movement of the upper halve 112a relative to the lower halve 112b. Other configurations are contemplated.

In the embodiment shown, the movement of the upper halve 112a relative to the lower halve 112b is controlled by a single motor 124, which may be hydraulic or electric. A system similar to the one described with reference to FIGS. 1-6 may be used. More specifically, rails may be secured to the edges of the lower sections 118a₂ of the lateral walls 118a. Gears that are in a mating engagement with the rails may be drivingly engaged by the motor 124 for inducing a translation of the upper halve 112a relative to the lower halve 112b along axis L. Any suitable transmission system may be used to transmit a rotational input of the motor 124 to said gears.

In the embodiment shown, the compactor 22 is driven by the same motor 124 that induces the translation of the upper halve 112a. Stated otherwise, only one motor 124 is used to drive both the compactor 22 and to move the upper halve 112a. It is understood that any suitable device, such as a clutch, may be used to direct the rotational input of the motor 124 to the desired function (e.g., compacting or emptying/discharging). In the embodiment shown, a discharging opening 112d corresponds to a bottom portion of the container 112. The floor 118c is used to close the discharging opening 112d. To open the opening 112d, the floor 118c is moved relative to a remainder of the container 112.

In particular embodiment, the motor 124 may be selectively drivingly engageable in a compacting configuration and in a discharging configuration. In the compacting configuration, the motor 124 may be in driving engagement with the compactor 22, more specifically to the compactor screw 22a. In the discharging configuration, the motor 124 may be in driving engagement with the rails such as described with reference to FIGS. 1-6 for moving the ejector panel 34 for discharging or emptying the container 112. The motor 124 may be drivingly disengaged from the rails when operated in the compacting configuration and may be drivingly disengaged from the compactor 22 in the discharging configuration.

As aforementioned, the first and second end walls 114, 116 and the compactor 22 move with the upper halve 112a of the container 112. Hence, the second end wall 116 is not a door and is fixed to a remainder of the container upper halve 112a. Therefore, in this embodiment, there is no requirement to use actuators to open the door. In a particular embodiment, the reliability of the disclosed waste collecting device 102 is better than that of a device using hydraulic actuators because such actuators are known to be less efficient in cold temperatures. Moreover, the waste collecting device 102 might be more efficient than a similar device having hydraulic actuators because such actuators are very energy consuming.

For operating the waste collecting devices 10, 102, waste is received in the compactor 22 that is located outside the waste receiving volume V of the container 12, 112. The waste is pushed in the waste receiving volume V through the waste opening 20, 34a defined in the ejector panel 34, 134. For emptying the container 12, 112, the ejector panel 34, 134 moves relative to the floor 18c, 118c of the container 12, 112 toward the rear end 12b. In the embodiment of FIGS. 7-8, the ejector panel 134 moves with the compactor 22.

In a particular embodiment, the waste collecting devices 10, 102 equipped with the screw conveyor 22 are more efficient than other devices equipped with other types of compactor because screw conveyors have a higher compaction ratio than other devices for a same amount of energy. In both of the above-described embodiments, the containers 12, 112 remain parallel to the ground. Hence, a stability of such devices 10, 102 is better than other waste collecting device requiring tilting the container for discharging. Moreover, keeping the container parallel to the ground allow discharging the waste in low-ceiling facilities. Not having to tilt the container might allow for a reduction of parts and installation time because there is no requirement to install hydraulic hoses and electric wires via a hinge. This might allow an economy in parts and in installation time for the disclosed waste collecting devices compared to a device where the container is hingely mounted to the vehicle's frame. In a particular embodiment, the ejector panel 34, 134 is more effective in emptying the container compared to gravity. Hence, an operator might be required to clean the container less frequently compared to a device where the container must be tilted.

As can be understood, the examples described above and illustrated are intended to be exemplary only. The scope is indicated by the appended claims.
