Description

DK 2021 70558 A1 1 [Underground waste collecting system]
Field of the Invention
The present invention relates to waste collecting system comprising a waste collection container.
Background of the Invention
A waste collection container may be a substantially closed container comprising a waste receiving opening, where the waste collection container may be fully sunken or half- sunken waste container or arranged fully on the ground. The storage capacity may in some cases be situated underground and/or above ground. The waste collection con- tainer is suitable for collecting separated waste fractions, such as paper, glass, organic waste, textiles, refuse, drink cartons, and synthetic packaging. It fits all standard lifting systems including round-headed and three-point hooks.
The waste collection container is suitable for collecting separated waste fractions, such as paper, glass, organic waste, textiles, refuse, drink cartons, and synthetic packaging.
Even though the storage capacity in the underground waste container may be large, the waste takes up a lot of storage capacity per unit. The waste collection container must be emptied often according to a maintenance schedule, which is costly and often a difficult task in cities. The waste collection vehicle is often parked, when emptying the waste collection container, in such way that the truck poses a problem to the rest of the traffic.
Object of the Invention
It is an object of the invention to provide waste collection system and a method for compressing waste inside a waste collection system, to reduce the volume of waste in- side a container, and thereby reducing maintenance costs and traffic problems. This invention addresses this issue and additionally provides a number of further advantages.

The present invention addresses this by providing a waste collection system, wherein the waste collection system has a waste collection container comprising a volume con- figured to receiving waste, wherein the waste collection container comprises: - an upper container member, wherein the upper container member partly encloses an upper volume, and the upper container member has an upper volume opening and an
DK 2021 70558 A1 2 inner cross-sectional circumference of the upper volume opening, wherein at least one receiving passage is arranged in the upper container member, such that the upper vol- ume is in communication with the ambient surroundings and the receiving passage is configured to receiving waste, such that the waste enters the volume, wherein at least one cover is arranged onto the upper shell, such that the cover is capable of covering the receiving passage or part of the receiving passage, - a lower container member enclosing a lower volume, wherein said lower container member has a top opening adaptable to the upper volume opening, such that said upper volume is in communication with said lower volume, - a pressing device arranged in a top part of the upper container member in a first posi- tion, wherein the pressing device comprises a pressing plate and a pressing means for compressing waste in waste collection container, wherein the pressing means is ar- ranged between a top part of the upper container member and said pressing plate, wherein the pressing means is configured to compress waste inside the waste collection container by displacing the pressing plate from the first position to a second position inside the waste collection container, such that when the pressing plate is being dis- placed, the pressing plate passes the waste receiving aperture when being displaced.
A waste collection container is a solution for integrating a large storage in a stylish manner and at the same time creating a hygienic environment to deposit waste. The waste collection container is suitable for collecting waste, such as paper, glass, organic waste, textiles, refuse, drink cartons and synthetic packaging.
The waste collection system comprises a waste collection container having a volume configured to receiving waste. The waste collection container may be arranged in an erected, reclining or horizontal position. The waste collection container comprises an upper container member and a lower container member. The upper container member may be arranged above the ground level. The lower container member may be arranged below or partly below ground level. The upper container member comprises lifting means for lifting the waste collection container out from the ground, such that the waste collection container can be emptied.
The upper container member and the lower container member forms a tube-shaped waste collection container, having an equal inner cross-sectional circumference in the
DK 2021 70558 A1 3 entire waste collection container. The tube-shape may be quadrangular, oval, or circu- lar. The upper container member and the lower container member may be provided with different shapes.
The upper container member encloses an upper volume. The upper container member has an inner cross-sectional circumference and inner cross-sectional shape. The upper container member has an upper volume opening with an inner cross-sectional circum- ference. The upper volume opening is also provided with an inner cross-sectional shape.
At least one receiving passage is arranged in the upper container member, such that the upper volume is in communication with the ambient surroundings and the receiving passage is configured to receiving waste. The lower container member encloses a lower volume. The lower container member has a top opening adaptable to the upper volume opening. The upper volume is in communication with said lower volume, such that the waste may enter the volume of the upper container member and fall into the volume of the lower container member.
The waste, when entering the volume of the waste collection container, may pile up from the lower volume and then up to the upper volume. Waste such as paper, glass, organic waste, textiles, refuse, drink cartons and synthetic packaging takes up a lot of space inside the waste collector container. A cover or covers, lids, doors etc. are pro- vided to cover the receiving passage.
The pressing device is arranged in a top part of the upper container member in a first position, which is where the pressing device is in a collapsed position. The pressing device is attached in a first end to the top part of the upper container device. In a col- lapsed position, the pressing device is configured to be arranged between the top part and the receiving passage. The pressing device comprises a pressing plate. The pressing device also comprises pressing means for compressing waste in the waste collection container. The pressing means may be arranged between a top part of the upper con- tainer member and said pressing plate. The pressing plate may be arranged such that the pressing plate is parallel to the ground level. The pressing plate may be arranged in a horizontal plane, such that the pressing plate is capable of cover the upper volume
DK 2021 70558 A1 4 opening. The pressing plate may for example move away from the top part of the upper container member towards a bottom part of the lower container member or vice versa.
The pressing means is configured to compress waste inside the waste collection con- tainer by displacing the pressing plate from the first position to a second position inside the waste collection container, when the waste collection container is in use. The dis- placing of the pressing plate may be substantially vertical, substantially horizontal and/or substantially sideward. The pressing plate is moved away from the top part of the upper container member towards a bottom part of the lower container member, or vice versa. Alternatively, the pressing plate is moved away from a first position at a first side part of the upper container member to a second position at a second side part of the upper container or vice versa. the first position at the first side part of the upper container member may be arranged opposite to the receiving opening. The second position at a second side part of the upper container may be arranged at the same side part as the receiving opening. Alternatively, the pressing plate is moved away from a first side part of the lower container member to a second side part of the lower container or vice versa.
The pressing plate passes the waste receiving passage when being displaced. The re- ceiving passage is preferably covered to prevent accidents from happening when the pressing device is activated.
The waste collection system considerably increases the collection capacity. The collec- tion frequency is reduced, leading to lower costs and negative impacts on the environ- ment such as reduction of emissions, noise, and traffic.
The pressing device may easily be integrated into existing waste collection containers.
The upper container member and the lower container member may be arranged in a horizontal plane relative to each other. The pressing device is attached in a first end to the top part of the upper container device, wherein the top part is arranged in the oppo- site end of the upper volume opening.
When placing the pressing device in top of the upper container member, away from the ground level and above the receiving passage, ensures that the waste is always below the pressing device and the waste will be compressed when the pressing device is acti- vated. The waste collection system thereby reduces the volume of waste inside the waste
DK 2021 70558 A1 collection container, and thereby reducing maintenance costs and traffic problems, due to larger interval for emptying the waste collection container.
In an advantageous embodiment of the invention the cross-sectional circumference of 5 the upper volume opening is equal to or smaller than an inner cross-sectional circum- ference of the bottom container member.
The lower container member encloses a lower volume. The lower container member has an inner cross-sectional circumference and inner cross-sectional shape. The lower container member has a top opening with a cross-sectional circumference. The top opening is also provided with a cross-sectional shape.
The upper container member may have an inner cross-sectional circumference equal to the bottom container member. The inner cross-sectional circumference of the upper container member may be equal to the cross-sectional circumference of the upper vol- ume opening. The cross-sectional circumference of the top opening of the lower con- tainer member may be equal to the inner cross-sectional circumference of the bottom container member. The cross-sectional shape of the top opening of the lower container member may be equal to the inner cross-sectional shape of the bottom container mem- ber. The upper container member and the lower container member may form a substan- tially uniform tube-shaped waste collection container, having an equal inner cross-sec- tional circumference in the entire waste collection container.
Since the upper container member and the lower container member are provided with a similar inner cross-sectional circumference, and the similar cross-sectional shape, the pressing device may be configured to compress waste inside the waste collection con- tainer by substantially vertically displacing the pressing plate from the first position to a second position inside the waste collection container, such that the pressing plate is capable of being displaced systematically upwards or downwards in the upper container member and the lower container member.
The upper volume opening may be smaller than an inner cross-sectional circumference of the bottom container. The upper container member and the lower container member may form a substantially non-uniform tube-shaped waste collection container, so that
DK 2021 70558 A1 6 the waste collection container has more than one inner cross-sectional circumference.
The upper container member and the lower container member may form a substantially non-uniform tube-shaped waste collection container, so that the waste collection con- tainer has more than one inner cross-sectional shape.
In a further advantageous embodiment of the invention the second position inside the waste collection container is the upper volume opening, such that the pressing plate is displaced from the first position to the second position at the upper volume opening, such that the pressing plate is displaced inside the upper container member of the waste collection container.
The inner cross-sectional circumference of the upper member may be smaller than the inner cross-sectional circumference of the bottom container member. The inner cross- sectional shape of the upper member may be different than the inner cross-sectional shape of the bottom container member. If upper container member has an inner cross- sectional circumference and/or inner cross-sectional shape compared to the bottom con- tainer member inner cross-sectional circumference and shape, the pressing device may only operate within the upper container member.
The pressing device may still be arranged in a collapsed position the top part of the upper container member. The pressing device may be configured to compress waste by substantially vertically displacing the pressing plate from the first position to a second position inside the upper container member. The second position inside the waste col- lection container may be limited to the upper volume opening. The second position may be a predetermined position, preferably a position between the receiving passage and the upper volume opening in the upper container member. If the pressing device enters the lower container member the waste may risk entering the frame side of the pressing plate, such that the pressing device gets stocked. It is the advantages of the waste col- lection system to prevents the waste to access the opposite side of the pressing plate, wherein the opposite side of the pressing plate is the side opposite to the pressing side.
In a still further advantageous embodiment of the invention the pressing means com- prises a moveable frame, which is arranged between a top part of the upper container member and said pressing plate, wherein at least one moving means attached to the
DK 2021 70558 A1 7 moveable frame, such that the moveable frame is capable of substantially vertically dis- placing the pressing plate from a first position to a second position inside the waste collection container.
The pressing device comprises a pressing plate and a pressing means for compressing waste in the waste collection container. The pressing means may be arranged between a top part of the upper container member and the pressing plate. The pressing means may comprise a moveable frame or similar. The frame may be collapsed or extended.
When the frame is collapsed the pressing plate is arranged in a first position. When the frame is more or less extended the pressing plate is arranged in a second position. At least one moving means attached to the moveable frame, such that the moveable frame is capable of substantially vertically displacing the pressing plate from a first position to a second position inside the waste collection container. The top part may comprise a removeable top plate. A first end of the frame may be attached to the removeable top plate. The pressing plate is attached to a second end of the frame. The pressing plate may be displaceable relative to the top part when activating the moving means. The moving means may be actuators. The actuators may be operated electrically, hydrau- lically and/or pneumatically.
In a further advantageous embodiment of the invention the pressing plate has a circum- ference and shape which correspond to the inner cross-sectional circumference and in- ner cross-sectional shape of the upper volume opening and/or to the inner cross-sec- tional circumference and inner cross-sectional shape of the upper container member, such that when compressing the waste, the waste is pressed towards the bottom part of the lower container member.
The upper container member has an inner cross-sectional circumference and/or inner cross-sectional shape. The pressing plate has a circumference and shape, which corre- spond to the inner cross-sectional circumference and inner cross-sectional shape of the upper volume opening and/or to the inner cross-sectional circumference and inner cross- sectional shape of the upper container member, such that when compressing the waste, the waste is pressed towards the bottom part of the lower container member.
DK 2021 70558 A1 8
The pressing plate corresponds to the shape and size of the inner cross-sectional dimen- sions. If the rim of the pressing plate extends to the inner side of the upper container member, the pressing plate will prevent the risk of waste entering the frame side of the pressing plate, such that the pressing device doesn’t get stuck. It is the advantages of the waste collection system to prevent the waste accessing the opposite side of the press- ing plate, wherein the opposite side of the pressing plate is the side opposite to the pressing side.
In a still further advantageous embodiment of the invention the bottom part of the lower container member is releasable attached to the lower container, a circumference of the bottom part is substantially equal to an inner cross-sectional circumference of the bot- tom container, such that the waste can be removed through the bottom part of the lower container member by releasing the bottom part from the lower container.
The pressing plate has a circumference and shape, which correspond to the inner cross- sectional circumference of the tube-shaped waste collection container. When compress- ing the waste, the waste is pressed towards the bottom part of the lower container mem- ber. The bottom part of the lower container member may be pivotally, releasably at- tached or slidably attached to the lower container member. The bottom part may be fastened by the use of releasable locking means. The circumference of the bottom part may be substantially equal to an inner cross-sectional circumference of the bottom con- tainer member. The waste can easily be removed through an opening provided in the bottom by releasing the releasable locking means. An opening in the bottom of the lower container member will release the waste from the waste collection container.
In a still further advantageous embodiment of the invention the waste collection system comprises a control system, wherein the control system controls the pressing means, such that the pressing means displaces the pressing plate from a first position to a second position or visa verse inside the waste collection container.
The waste collection system also comprises a control system which is not showed in the figures. The control system controls the pressing means, such that the pressing means displaces the pressing plate from a first position to a second position and vice versa inside the waste collection container. The control system comprises sensing means for
DK 2021 70558 A1 9 sensing the cover’s position relative to the waste receiving aperture. The pressing means is configured to displace the pressing plate from a first position to a second position inside the waste collection container, when the waste receiving aperture is covered.
In a further advantageous embodiment of the invention the control system comprises sensing means for sensing the cover position relative to the waste receiving aperture, such that the pressing means is configured to displace the pressing plate from a first position to a second position inside the waste collection container, when the waste re- ceiving aperture is covered.
The control system comprises sensing means for sensing the cover position relative to the waste receiving aperture. The pressing means may be configured to displace the pressing plate from a first position to a second position inside the waste collection con- tainer, when the waste receiving passage is covered. If the receiving passage is not cov- ered, the control system is waiting to start the pressing process until the waste receiving passage is covered.
The invention also provides a method of compressing waste inside a waste collection system, wherein the waste collection system comprises a waste collection container having an upper container member and a lower container part, comprising following steps: - arranging said upper container member above the ground level, and arranging the lower container member fully or partly below ground level, - entering waste into upper container member through a receiving passage, - displacing the pressing plate from the first position between a top part of the upper container member and the receiving passage, to a second position between the receiving passage and the bottom part of the lower container member inside the waste collection container.

The inner cross- sectional circumference dl of the upper member 2 is smaller than the inner cross-sec- tional circumference d2 of the bottom container member 3. The cross-sectional circum- ference of the top opening is smaller than the inner cross-sectional circumference d2 of the bottom container member 3.
A pressing device 10 is arranged in the top part 11 of the upper container member 2, positioned in a first position. The pressing device 10 is configured to compress waste by substantially vertically displacing F the pressing plate 14 from the first position P1 to a second position inside the upper container member 2. The second position P2 inside the waste collection container is the upper volume opening. The pressing plate is dis- placed from the first position to the second position P2 at the upper volume opening, such that the pressing plate is displaced only inside the upper container member of the waste collection container. The second position P2 is a position between the receiving passage and the upper volume opening in the upper container member 2. If the pressing device 10 enters the lower container member 3 the waste may risk entering the frame side of the pressing plate 14, such that the pressing device 10 gets stuck.
The pressing plate 14 is displaced using actuation means, such as using at least one actuator 16. The pressing plate 14 moves away from the top part 11 towards the bottom part 8 of the lower container member 3 but stops at the upper volume opening. Or the pressing plate 14 moves towards the top part 11 away from the bottom part 8 of the lower container member. The pressing plate 14 passes the receiving passage, when be- ing displaced upwards or downwards.
The waste collection system also comprises a control system which is not showed in the figures. The control system controls the pressing means, such that the pressing means displaces the pressing plate from a first position to a second position and vice versa inside the waste collection container. The control system comprises sensing means for sensing the cover’s position relative to the waste receiving passage. The pressing means is configured to displace the pressing plate from a first position to a second position inside the waste collection container, when the waste receiving passage is covered.
