Definitions

  • TECHNICAL FIELD This invention relates the field of trash compactors, in particular solar powered trash compactor
  • Trash collection and disposal is an important part of the modern world. Trash bins are essential anywhere people are likely to traffic. Servicing trash bins traditionally involves a high degree of manual labour to inspect and swap trash receptacles, and heavy machinery for the collection and aggregation of multiple bins. This incurs substantial labour costs for the service provider, and environmental costs due to the movement of waste collection vehicles. It is well known that devices that can alert service providers to the fill level of trash bins can reduce the cost of labour by allowing service providers to only send personnel to bins that require servicing. It is also well known that compacting bins increases the effective capacity of each bin, therefore delaying the need for collection. Fewer truck movements translates to lower fuel costs and reduced exhaust emissions and equipment wear.
  • US Patent 4147100A from 1978 discloses a portable trash compactor.
  • Smart Bins including the cost and complexity of service, and the reluctance of some users to use handles or foot pedals where once they simply tossed rubbish into an open chute.
  • the invention disclosed herein addresses some of the limitations of current art in terms of serviceability and reliability. It also discloses methods to improve the operational safety of public trash compactors. It also discloses apparatus and methods for public trash compactors where the threat of improvised explosive devices is present.
  • the modern "Smart" trash compacting bin as disclosed in prior art contains power supplies, batteries, embedded computers, electromechanical components as well as complex software and network communications devices. The malfunction of even one of these components may render the entire apparatus out of service. Sending skilled technician to the location of malfunctioned bins incurs higher costs than utilising staff already onsite.
  • the present invention discloses an apparatus that improves on previous trash compacting bins by reducing the cost of maintenance and improves options for users to control the appearance of their smart bins. This is achieved by aggregating the complex components of compacting bins into a single module and making that module removable and interchangeable. These components are the components most likely to require servicing, and when serviced require specialist equipment or trained personnel.
  • the module slides or clips into the main trash container which is the exterior of the bin and is secured in place by means of traditional fasters or mechanical lock.
  • a small number of simple devices such as
  • RO/AU as the solar panel or door switch can be mounted on the exterior shell and connected or integrated into the removeable compactor module.
  • the devices external to the compactor module should be minimised, and the connectors linking these devices should be themselves minimised to reduce part count.
  • these should be of a style that requires no interaction by the user, other than aligning the compactor module in the right position.
  • the exterior bin shell can be installed without the compactor module, allowing clients to have a single bin design across their site, and selectively adding compaction modules where required.
  • compactor modules can be removed and
  • Spare compactor can be held by the service providers for a fast field replacement, and out of service units can be sent away for workshop service. This results in reduced downtime for the bin, and lower overall cost of maintenance.
  • Crush injury is an inherent risk of compacting bins, especially since users will be of diverse demographic and age groups. Furthermore, many cities operate container deposit schemes which pay for containers returned to collection depots. It is observed that in these cities some users collect such containers from public waste bins to claim the deposit refunds. This presents a further risk as users reach in to the area crushed by the compactor mechanism. Prior art inventions have disclosed methods for mitigating these risks through the use of hoppers and chutes. However, these have some limitations.
  • Hoppers provide a safe physical separation between the user and the compaction mechanism.
  • many articles on the internet discuss the hygiene concerns about hopper handles by members of the public. It is also evident that hoppers can be rendered out of service by irregular shaped trash items such as large pizza boxes and fast food bags which are larger than the hopper capacity. When such items become lodged in the hopper instead of falling into the waste receptacle, further trash cannot be deposited. This renders the bin out of service, and further items of trash forcibly inserted cause trash to overflow.
  • Prior art reveals another invention discloses a trash compacting bin with a flap covering the trash input chute wherein the compaction is stopped when the flap is pushed.
  • pushing trash against a flap can be unhygienic if the condition of the bin is dirty.
  • Prior art reveals yet another invention discloses a trash compacting bin with a motorised flap that opens on detection of a user present, however this action consumes electricity and may be unsuitable for solar powered trash compactors where stored power is limited.
  • Prior art reveals another invention discloses a compacting bin with no hopper or flap but uses a photoelectric cell at the opening of the trash input chute to detect obstructions. If the PE cell is interrupted the compaction motor is isolated for user safety. If has been observed in the public domain that periodically when trash is placed in the chute and does not fall into the receptacle but remains blocking the PE beam, the safety mechanism of the bin is activated, and compaction is ceased, rendering the bin out of service. Additionally, it is observed that some users view PE beams as being less safe than a physical barrier as reflections in the trash can potentially affect beam performance. Furthermore, there exists theoretical risk that a small limb such as that of a child may fit through the chute without disrupting the PE beam. Even if these technical problems are resolved, the public perception of the safety risk may persist.
  • the current invention discloses an apparatus and method which in the
  • RO/AU contains a flap that is normally open, making the trash compactor bin convenient and familiar for users. The flap is closed prior to compaction, A sign affixed on the flap informs users that the bin is compacting.
  • the flap is neutrally closed, but an actuator
  • the present invention anticipates that users may push against a flap when it is closed.
  • several solutions are disclosed that allow the flap to swing open when closed, whilst allowing the actuator to push the flap open from the closed position. These include a cam-follower mechanism linking the actuator to the flap.
  • the bin uses an actuator to shift a counterweight to affect the neutral position of the flap between closed and open.
  • Prior art discloses a chain lever system for compacting trash. This method provides useful mechanical advantage and is simple and theoretically more reliable. The compactor must be at least twice the height of the receptacle to reach the bottom. Prior art reveals the design of a bin with a receptacle of approximately 600mm and total height of over 1200mm. However, in many cases where cities prefer the use of industry standard wheelie bins with a
  • scissor mechanisms consist of a plurality of sets of scissor pairs, connected in an accordion-like sequence with each scissor being connected to the next via its distal pivots.
  • Scissor mechanism allow the depth of the extension to be changed based on the number of scissor pairs fitted. This makes scissor compactors suitable for use with wheelie bins.
  • the prior art discloses mechanisms which translate horizontal force applied to the top distal pivots into vertical downwards force transmitted to the compaction plate. The relationship between the horizontal and vertical forces vary according the angle of the scissor arms in a non-linear force curve. This results in lower forces available when the scissor is retracted, an undesirable characteristic since this is when the trash reception is likely full.
  • This invention discloses apparatus and methods for compacting trash
  • Wheelie bins are manufactured in industry standard sizes and are a convenient to move heavier loads so provide greater capacity than traditional waste bins.
  • the standard 240 Litre Wheelie bins provides over twice the size of the standard street litter bin in the US due to the increased height of the receptacle.
  • This invention discloses in a preferred embodiment a scissor-accordion
  • scissor mechanism is maintained by means of a vertical slot which contains the pivot of a plurality of scissor middle pivots.
  • This invention discloses a method for making use of more of the available stored power.
  • an onboard computer in the trash compacting bin constantly monitors the power absorbed from sunlight and the power. As battery capacity decreases, the computer sets progressively lower force and range outputs on the compactor. This trades battery endurance for compaction capacity.
  • RO/AU reporting service conditions related to the operation of compacting bins In the preferred embodiment, using a video camera mounted inside the bin, the bin is able to capture images of both the chute and trash receptible. If a fault or obstruction to the chute is detected, the bin transmits the image to a remote computer. The remote user is then able to diagnose the fault and perform service actions or send the appropriate service personnel.
  • This invention discloses a method for detecting and alerting users of potential improvised explosive devices deposited in the trash compactor.
  • a metal detector fitted to the trash input chute detects the volume and type of metal.
  • a weight sensor detects the mass of the bin periodically. If an item is deposited in the bin matches a range of profiles saved on the onboard computer, the bin closes the chute, ceases all compactions, captures an image and sends the alert to a remote computer.

  • a set of shorter scissor arms (32) link to the distal pivots of the next scissor. This arrangement has the benefit of transferring force from the scissor to the fixed top member (16) and keeping the scissor centred on the plate.
  • RO/AU configuration requires the screw jack and supporting bearings to resist lateral forces that may bend the screw mechanism but reduces the complexity of the mechanism. Making the screw mechanism and supporting bearings sufficiently rigid will overcome the lateral forces.
