Abstract

A waste compactor comprises a tubular bin (11) initially open at each of its opposite ends; a normally upstanding column (13) to which the bin is secured; a base (12) from which the column (13) rises and on which the bin (11) stands; a ram (15) fixed to the column and positioned over the top of the bin; and a plate (16) fixed to the ram and movable into and out of the bin by the ram to compress waste stored in the bin. The plate (16) is so sized and shaped that when moved into the bin by the ram it effectively closes off the top end of the bin. The bin is movable by rams (17, 18), away from the base, relative to the column and the ram to allow the compressed waste to be discharged into a plastic sack secured about the bin's bottom end. The plate (16), ram (15) and parts (13c) and 13(b) of the column may be swung sideways off the top of the bin to give access to the bin. <IMAGE>

Description

SPECIFICATION Waste compactor The invention relates to waste compactors.
U.K. Patent Specification No. 1 299 659 shows a waste compactor in which a tubular element (the bin) has a bottom plate (the base) detachably connected to one end of the tubular element; a cover is pivotally connected to the other end of the tubular element; and a ram and pressure plate are housed inside the cover. A container, for example a flexible plastic bag, fits over the initially open bottom end of the bin and around the outside of the wall of the bin.
Tubular guide rods enable the bin to be raised and lowered relative to the bottom plate.
Waste loaded into the top end of the bin is compressed by the ram and pressure plate until the bin is full. The bin then rises vertically on its guide rods and in so doing automatically discharges the compressed waste into the flexible plastic bag. The bag full of waste is removed from underneath the bin, is sealed to package the waste, and can then be disposed of. A new and initially empty plastic bag is fitted over the open bottom end of the bin and around the outside of the bin wall, and the bin returns to its original position around the bottom plate to be filled again with waste which is discharged into the plastic bag in the manner just outlined.
In practice the arrangement shown in Specification 1 299 659 has never achieved widespread commercial success. Most probably this is because it is not practical to mount inside the cover a ram of sufficiently high compressive strength; or because it is not possible to arrange a cover hinge which can successfully take the force of reaction generated by such a ram; or there may be other reasons. Whatevear the reasons, the arrangement has remains purely a paper propsal.
In the commercially successful embodiment produced by the assignees of Patent 1 299659 the compressing ram is mounted on top of the pressure plate, the pressure plate constitutes the cover as well as fulfilling its compressing functions, and this combined plate and cover is not hinged to the bin but can be removed horizontally off the top of the bin in a slideway to uncover the top end of the bin for loading with waste. This enables a ram of adequate compressive strength to be used.
Unfortunately the ram cylinder still moves up and down with the bin as the bin rises for bag-discharge.
It is all to easy for the protruding ram cylinder to hit the ceiling of the room or alcove in which the compactor stands. The arrangement therefore still has drawbacks.
The present invention seeks to produce a compactor which will overcome these drawbacks.
According to the invention a waste compactor comprises a tubular bin, initially open at each of its opposite ends; a normally upstanding column to which the bin may be secured and alongside which the bin stands, in use, with the bottom end of the bin resting on the ground on which the column stands or resting on a base from which the column rises; a ram fixed to the column and positioned over the top of the bin; and a plate fixed to the ram and movable into and out of the bin by the ram to compress waste stored in the bin; the plate being so sized and shaped that when moved into the bin by the ram it effectively closes off the top end of the bin; and the bin being movable, away from the ground or away from said base, relative to the column and the ram to allow the compressed waste to be discharged from the bin's bottom end.
Such a compactor can be used in essentially the same way as that shown in Specification 1 299 659, and the practical embodiment of that specification outlined above, whilst avoiding the major drawbacks of both. Because the compressing ram protrudes above the top end of the bin, rather than being foreshortened inside the cover of the bin, a ram of adequate length and compressive strength can be used; but because the ram is mounted on the column and does not move with the bin for wastedischarge the danger of the top end of the ram cylinder inadvertently hitting the ceiling is avoided.
Within its broad aspect the invention encompasses a number of other realisations none of which is apparent from Specification 1 299659 or from the practical embodiment of that specification outlined above.
For example, the bin need not necessarily be secured to the column. It could stand freely along side the column and be automatically kept in position by the compressing plate during waste compression.
Neither need the bin necessary be loaded with waste from above, i.e. via its open top end. It could for example incorporate a loading opening located towards its top end but formed in its sidewall.
Conveniently however, the bin may be intended to be loaded from its top end, and so the ram may retract the compressing plate sufficiently far to uncover the top end of the bin. This is possible since the ram and compressing plate are not fixed to the bin but can rise above it to any practical desired height.
Alternatively the plate may be movable generally horizontally about the column to uncover the top end of the bin for loading. The plate and ram may move together about the column to uncover the bin, preferably swinging rather than sliding, since (a) a swinging unit is easier to move than a sliding unit if the slideway becomes jammed and (b) there is less danger of an operator's fingers being trapped if he only has to push aside a swinging unit rather than having to slide a sliding unit along partly-enclosed sliding channels.
The bin, if secured to the column, may be movable linearly away from the ground or away from said base to allow the compressed waste to be discharged from its bottom end. A linear rising-bin arrangement is shown in Specification 1 299 659.
Alternatively the bin may move in a curve away from the ground or away from said base for wastedischarge. This avoids the need for vertical guides of the kind shown in the prior specification; instead, the bin may simply be pivoted horizontally to the column or may be guided without being pivoted so that it rises non-linearly from the base.
The bin movement for waste-discharge may be power operated and may be effected by one or more further rams acting between the bin and a base on which the bin stands, as in the prior specification.
However the or each bin-moving ram may act between the bin and the column, especially where the bin pivots horizontally about the column as just outlined, or between the bin and the ground on which the bin stands. Neither of these arrangements is foreshadowed in the prior specification.
In any case in which the bin movement is power operated, the or each bin-moving ram is preferably unpressurised, rather than being pressurised but mechanically restrained, when the bin is not being moved. In the practical embodiment of Specification 1 299 659 referred to above, the bin-moving rams are permanently pressurised and, if the mechanical restraining means are accidentally released, the bin and the protruding compressing ram cylinder fixed to it can suddenly shoot up from the base. This could be very dangerous.
Conveniently there may be two bin-moving rams each located diametrically opposite one another across the bin. Preferably each ram in such a case acts in unison for a smoother and more controlled bin movement. Preferably also the two rams are each mounted as close sa practicable to the bin sidewall, so that the overall width of the bin and its rams (and of any base on which they stand) is kept to a practical minimum. This enables the compactorto be manoeuvred into restricted-width spaces and through standard-sized doorways if the dimensions are appropriately chosen.
If the column rises from a base, and the bin stands in use on that base, the base may be strengthened by ribs running along and across it. This enables a compressing ram of high strength to be used, since such a rib-strengthened base will more readily resist - the force of reaction from the ram.
The necessary hydraulic hose to the wastecompressing ram may, for safety, be enshrouded within the column to which the ram is fixed.
If the bin moves up over the compressing plate for waste-discharge, there may be an arm fixed to the compressing plate and rising from the plate to end in an out-turned portion which, as the bin rises, contacts the top rim of the bin to prevent the compressing plate from coming out of the bottom of the bin.
If the bin is intended to compress and discharge a variety of waste, especially liquid or granular waste, then (as outlined in Specification 1 299 659) a container such as a flexible plastic bag may fit over the bottom end of the bin and around the outside of the bin wall. The walls of such a container would not contact the waste inside the bin whilst the waste was being compressed, but when the bin was moved away from the base the compressed waste could then be discharged direct into the container before removing the container from the bottom end of the bin, sealing it to package the waste, and disposing of it.
However such a container is not essential to a compactor embodying the present invention. When dealing with certain kinds of dry waste, for example cardboard boxes and sheets, the container might be dispensed with and the waste safely discharged and removed in an unpackaged dry compressed mass.
One waste compactor embodying the invention is shown in the accompanying perspective drawing. It is only an example of forms which the invention might take within its broadest aspect. It will now be described with reference to the drawing.
A circular-cylindrical tubular bin 11 is initially open at each end. It stands with its bottom end on a rectangular base plate 12 from which an upstanding column 13 rises. The column 13 is in three parts: a bottom part 13a which is fixed to the base 12 and which houses a hydraulic pump, pump-driving motor, and hydraulic fluid reservoir (not shown); an intermediate part 13which can swing horizontally about the bottom part 13a on a pivot bearing 14; and atop part 13which projects forwardly from the intermediate part 13b and is fixed to that intermediate part to swing with it about the pivot bearing 14.
The top part 13c of the column 13 houses a linear double-acting hydraulic ram 15. The ram 15 is positioned above the top end of the bin 11. A circular steel pressure plate 16 is fixed to the downwardprotruding rod of the ram 15. The pressure plate 15 can be moved into and out of the bin 11 by the ram 15.
When the plate 16 is inside the bin it is a close sliding fit on the bin wall and it effectively closes off the top end of the bin. When retracted, as shown in the drawing, it sits just above the top rim of the bin and it can be swung sideways, with its ram 15, on the upper part 1 3c of the column as that upper part is moved about the pivot bearing 14. When the ram and compressing plate are swung sideways off the top of the bin about the pivot bearing, the top end of the bin is uncovered for loading.
The bin 11 has its own rams secured to it. There are two of them referenced respectively 17, 18 and their cylinders are fixed diametrically opposite one another across the bin. The cylinders of each ram 17, 18 are secured to the outer surface of the bin wall by blocks 19, 21 in such a way that the ram cylincders are mounted as close as practicable to the bin wall.
The rod ends of each ram 17, 18 are fixed to the base 12 on which the bin stands and from which the column 13 rises. The rams 17, 18 are single-acting rams. When pressurised they raise the bin vertically from the base 12. To return the bin to its illustrated position on the base they are depressurised and the bin sinks under its own weight as the pressure in the rams gradually falls. The rams 17,18 effectively constitute a pair of vertical guides for the bin movement as well as providing the motive power for that movement.
The necessary hydraulic hoses to the rams 17, 18 are enshrouded in the bottom part 13a of the column and inside the flanged periphery of the base 12. The hose for the compressing ram 15 is enshrouded in the column, as is the ram itself. The base 12 is stiffened inside its periphery by ribs which run along and across the area of the base plate. These ribs extend the full depth of the peripheral flange around the base plate.
Castors (not shown) protrude from the underside of the base 12 and allow the compactor to be wheeled from one location to another.
A semi-circular shroud 22 is fixed to the top surface of the compressing plate 16 and rises from the compressing plate. The shroud 22 is a relatively loose sliding fit inside the bin 11. The shroud ends in an out-turned portion 22a which is larger in diameter than the bin's top-end rim.
To use the compactor, the rams 17, 18 are operated to raise the bin 11 slightly away from the base 12. Aflexible plastic bag, not shown in the drawings, is fitted over the open bottom end of the bin and around the outer surface of the bin sidewall.
The rams 17, 18 are depressurised and the bin sinks back down onto the base 12to trap the bottom of the plastic bag in between the bottom end of the bin and the base itself; and to bring its top-end rim down below and just clear of the bottom surface of the compressing plate 16.
The plate 16 and its ram 15 are swung aboutthe pivot bearing 14 to uncover the top end of the bin.
Waste is loaded into the bin through that top end.
The ram 15 and plate 16 are swung back into position over the top end of the bin. The ram is pressurised to move the compressing plate 16 down into the bin and compress the waste against the bottom of the plastic bag which is supported by the base 12. The ram 15 is pressurised in the opposite sense to retractthecompressing plate 16 and allow the plate to be swung sideways again off the top of the bin for further loading of waste. The cycle is repeated until the bin is substantially full with compressed waste.
When no more waste can be compressed into the bin, the plastic bag is tied or is held around the bottom end of the bin. The rams 17, 18 are pressurised to raise the bin vertically off the base 12, taking with it the top end of the plastic bag and gradually opening out the plastic bag vertically. At the same time, the compressing ram 15 is actuated to move the plate 16 down into the bin and on top of the compressed waste inside the bin. When the plate comes up against the waste, with the rams 17, 18 moving the bin upwards, the ram 15 stops extending but keeps the plate 16 firmly held against the compressed waste.When the top-end rim of the bin contacts the out-turned flange 22a of the shroud 22 in its upward movement, the compressing ram 15 is automatically actuated in the opposite sense and begins to retract as the bin continues to move further upwards on its rams 17, 18.
This upward movement of the bin automatically discharges the compressed waste into the verticallyopening plastic bag. When the bin reaches the limit of its upward movement, it stops automatically. The bag can then be sealed to package the waste and can be disposed of. The rams 17, 18 are depressurised to allow the bin to return towards the base 12. When the bin is some short distance away from the base 12, another plastic bag is fitted over the open bottom end of the bin and around the outside surface of the bin wall; and the bin is then allowed to return fully onto the base 12. The loading, compressing and waste-discharging cycle outlined above can then be repeated.
When the rams 17, 18 are not moving the bin, and the bin is in its illustrated position on top of the base 12, the rams are depressurised completely. Should there be a hydraulic failure the bin will then not suddenly shoot up off the base 12. For similar safety reasons the ram 15 is not pressurised to extend when it is not moving the compressing plate 16 down into the bin.

    Castors (not shown) protrude from the underside of the base 12 and allow the compactor to be wheeled from one location to another.
    A semi-circular shroud 22 is fixed to the top surface of the compressing plate 16 and rises from the compressing plate. The shroud 22 is a relatively loose sliding fit inside the bin 11. The shroud ends in an out-turned portion 22a which is larger in diameter than the bin's top-end rim.
    To use the compactor, the rams 17, 18 are operated to raise the bin 11 slightly away from the base 12. Aflexible plastic bag, not shown in the drawings, is fitted over the open bottom end of the bin and around the outer surface of the bin sidewall.
    The rams 17, 18 are depressurised and the bin sinks back down onto the base 12to trap the bottom of the plastic bag in between the bottom end of the bin and the base itself; and to bring its top-end rim down below and just clear of the bottom surface of the compressing plate 16.
    The plate 16 and its ram 15 are swung aboutthe pivot bearing 14 to uncover the top end of the bin.
    Waste is loaded into the bin through that top end.
    The ram 15 and plate 16 are swung back into position over the top end of the bin. The ram is pressurised to move the compressing plate 16 down into the bin and compress the waste against the bottom of the plastic bag which is supported by the base 12. The ram 15 is pressurised in the opposite sense to retractthecompressing plate 16 and allow the plate to be swung sideways again off the top of the bin for further loading of waste. The cycle is repeated until the bin is substantially full with compressed waste.
    When no more waste can be compressed into the bin, the plastic bag is tied or is held around the bottom end of the bin. The rams 17, 18 are pressurised to raise the bin vertically off the base 12, taking with it the top end of the plastic bag and gradually opening out the plastic bag vertically. At the same time, the compressing ram 15 is actuated to move the plate 16 down into the bin and on top of the compressed waste inside the bin. When the plate comes up against the waste, with the rams 17, 18 moving the bin upwards, the ram 15 stops extending but keeps the plate 16 firmly held against the compressed waste.When the top-end rim of the bin contacts the out-turned flange 22a of the shroud 22 in its upward movement, the compressing ram 15 is automatically actuated in the opposite sense and begins to retract as the bin continues to move further upwards on its rams 17, 18.
    This upward movement of the bin automatically discharges the compressed waste into the verticallyopening plastic bag. When the bin reaches the limit of its upward movement, it stops automatically. The bag can then be sealed to package the waste and can be disposed of. The rams 17, 18 are depressurised to allow the bin to return towards the base 12. When the bin is some short distance away from the base 12, another plastic bag is fitted over the open bottom end of the bin and around the outside surface of the bin wall; and the bin is then allowed to return fully onto the base 12. The loading, compressing and waste-discharging cycle outlined above can then be repeated.
    When the rams 17, 18 are not moving the bin, and the bin is in its illustrated position on top of the base 12, the rams are depressurised completely. Should there be a hydraulic failure the bin will then not suddenly shoot up off the base 12. For similar safety reasons the ram 15 is not pressurised to extend when it is not moving the compressing plate 16 down into the bin.
