The sleeve is resiliently expandable and is positioned in the compaction zone of the machine so that the reciprocating ram compacts the refuse into the sleeve. When the sleeve is substantially filled with compacted refuse the sleeve is moved from the compaction machine, and then removed from the compacted refuse leaving the refuse in a packaging container.

23 Claims, 10 Drawing Figures PROTECTIVE SLEEVE FOR REFUSE HANDLING APPARATUS The present invention generally comprises a refusehandling system which is adapted to dispose of refuse from multi-story or single-story buildings, such as apartment houses, office buildings, residential dwellings and similar structures.

More specifically, the invention relates to a refusehandling system which is adapted to be used with refuse-compacting apparatus of the type using a reciprocating ram to compact the refuse into a specific size and volume. The invention can be adapted for use with either a horizontal-type compacting ram or a verticaltype compacting ram, such as the type disclosed in US. Pat. No. 3,424,078 and US. Pat. No. 3,74l ,107. In particular, the present invention involves a modification of and an improvement in the subject matter disclosed in the previously identified application when used to compact the refuse into a container or flexible package within the compacting zone of the machine.

BACKGROUND OF THE INVENTION Refuse-compacting equipment is increasingly being utilized to condense compressible solid and semi-solid materials to reduced-volume packages. These reduced- It is a still further object of this invention to accomplish the desired compaction and packaging by economical and inexpensive equipment which is easy to operate.

SUMMARY OF INVENTION The foregoing objects and advantages are obtained according to the present invention by a resiliently expandable sleeve having size dimensions approximating, but slightly smaller than, the dimensions of the com pacting zone of the compaction machine. The resilient volume packages serve to facilitate and expedite the handling of refuse from its source to its final destination by reducing its bulk. Refuse-compacting equipment has previously been used for large commercial buildings, but it is now available for single family type buildings and smaller commercial establishments. In conjunction with the transportation of refuse, it has become desirable to have the refuse packaged in a container or package. Flexible plastic bags or other thin, flexible containers are conventionally used for this purpose.

Previously, compacted refuse was placed into a package or container, such as a flexible plastic bag. The packaging of the compacted refuse constituted an arduous, time-consuming and sometimes impossible task since small pieces from the compacted refuse always fell away before the compacted refuse could be in serted into the bag. In order to overcome this problem and eliminate the necessity for packaging the refuse after it has been compacted, the present invention contemplates compacting and packaging the refuse at the same time by placing an open ended package or container in the compacting zone of the compacting machine and having the refuse compacted into the package or container itself. In order to accomplish simultaneous compacting and packaging in conventional flexible plastic bags or other thin packaging material or containers, it has been found essential to protect the inside of the bag or package from being torn, cut, split, etc., during the compaction gy glass, metal and other sharp rigid objects in the refuse being compacted.

Accordingly, it is a primary object of this invention to simultaneously compact and package conventional type refuse into packaging materials or containers.

It is another primary object of this invention to reduce bulk refuse with a ram-type compacting machine into a flexible plastic bag or other conventional refuse container or package.

It is a further object of this invention to accomplish such compaction inside the refuse container, without cutting, tearing, splitting, etc. the container during the compaction.

sleeve is inserted into the flexible plastic bag or other package or container, and then the bag or package containing the sleeve is placed into the compacting zone to receive bulk refuse to be compacted. The side walls of the compacting zone which surround the outside surface of the flexible bag or package are rigid and preferably smooth to prevent cutting or tearing of the bag during compaction. The compacting ram is shaped to compact the bulk refuse within the sleeve, and the sleeve is designed to resiliently expand against the rigid walls of the compacting zone under the force of the compaction. As a result, the sleeve and surrounding package are pressed against the side walls of the compacting zone.

DETAILED DESCRIPTION OF THE DRAWINGS The invention as shown in the figures comprises a modification and improvement of the refuse compacting apparatus and system disclosed in US. Pat. No. 3,741,107.

As shown in FIGS. I and 2, housing 20 has compacting means 22 mounted therein which is adapted to compact refuse in sleeve 24 placed within the housing. The basic function of the sleeve 24 is to provide protection for a flexible plastic bag 25, or other package constructed of suitable material, against cutting, tearing and abrasion caused by loading refuse containing glass, metal and other sharp, rigid matter into the refuse compactor for bulk reduction. This protection for bag 25 is achieved by inserting the sleeve 24 into the bag so that the inside vertical surfaces of the bag are fully protected by the sleeve during the compacting of the re fuse.

The walls of housing form an internal compacting chamber or zone 32 into which the sleeve 24 and bag 25 are placed. The walls are preferably smooth so that the bag 25 will not be torn or cut when in the compacting chamber 32 and sandwiched between the sleeve 24 and the walls of the compacting chamber 32.

The compacting means 22 as shown in FIG, 1 includes a cylinder 26 having a piston movably mounted therein, which is not shown. The piston carries an elongated piston rod 28, which has a suitable compressing ram or plate 30 secured thereto. The compacting plate 30 is preferably of the same cross-sectional configuration as, but slightly smaller than, the interior of sleeve 24 and is mounted to the piston rod 28 by suitable securing means such as bolt 34. lt should be noted that the cylinder 26 is held in position and the piston rod 28 is guided by a mounting and guide block assembly 36. The mounting and guide block assembly 36 is suitably secured to the housing 20 or to bracket or mounting means extending inwardly from the housing walls. The compacting means 22 is preferably driven by hydraulic fluid pumped from a pump means not shown. One such compacting means including the drive mechanism is disclosed in US, Pat. Nov 3,424,078. The compacting means 22 can use a single-acting hydraulic circuit or double-acting hydraulic circuit or any such hydraulic or pneumatic circuit which will allow the apparatus to operate efficiently. The housing 20 has a loading door 38, which is double hinged at 40 and 42 so that the door can be opened vertically from the housing for refusefeeding and swung horizontally from the housing for refuse removal.

Door hinge 40 is preferably secured to a horizontal arm 44 allowing the loading door 38 to travel vertically approximately for refuse loading.

The horizontal arm 44 is preferably pivotally mounted to the housing 20 so that it can be positioned adjacent the upper edge of a front plate 72 of a dolly assembly when the dolly assembly is mounted in the housing. The horizontal arm 44 is a structural member preferably spanning the width of the compacting ma chine and is mounted to the compacting machine by means of a vertically disposed hinge 42 at one extremity and a latch means at the other extremity. In the latched position. the horizontal arm 44 provides distributed load restraints to the upper boundary or edge of the dolly assembly front plate 72 against the lateral forces induced by the compression loading. For refuse removal, the latch means is released and the horizontal arm 44 is rotated or more about its hinge line, so that the dolly assembly 70 carrying the compacted refuse within the sleeve 24 and bag 25 can be withdrawn for disposal.

The sleeve 24 comprises a plurality of panels 50 and a continuous upper reinforcing rim 52 which is secured to the upper surface of each panel 50 by a preferred dimple construction 54 as shown in FIG. 3. The preferred dimple construction provides compression strength and rigidity to the upper perimeter of the panels 50 of the sleeve. The panels 50 are not intercon nected to each other except through their individual interconnection to the continuous reinforcing rim 52. As such, the panels 50 when subjected to a force normal to their surface. such as when refuse within the sleeve 24 is being compacted, can expand outwardly along their bottom edge about an axis defined by the continuous reinforcing rim 52. By designing the sleeve 24 to approximate the dimensions of the compacting chamber or zone 32, the panels 50 can expand during 5 compaction to thereby clamp the walls of the bag 25 against the rigid walls of the chamber permitting the walls of the chamber to act as the principal surfaces for the resisting of the outward movement of the refuse under the force of the ram 22.

The height of the plastic bag 25 is preferably maintained just below the rim 52. The bag is maintained in position by an elastic restraining strap or band 53 placed over the plastic bag holding it against sleeve 24. If desired, any portion of the plastic bag which would otherwise extend upward past the restraining band 53 can be doubled back over or under the restraining band.

Two of the panels 50, designated as panels 56, have handles 58 formed therein which are used to remove the sleeve 24 from the compacted refuse and the bag 25 after the package has been removed from the housing 20. The ability of the sleeve 24 to resiliently expand along its length facilitates removal of the sleeve from around the compacted refuse since the panels 50 can expand to accommodate removal of the sleeve. This ex pansion significantly reduces the friction forces which must be overcome to remove the sleeve from around the compacted refuse.

In addition, the other panels 50, designated as panels 60, have brace flanges 62 along their side edges which overlap the side edge of the adjacent paneis 56. This arrangement assists in avoiding tearing of the bag 25 resulting from the side edges of adjacent panels pinch Another embodiment of the sleeve is shown in FIG. 7. In this embodiment, the flanges 63 of the panels 60' are preferably trapezodial in configuration and overlap a significantly larger portion of the adjacent panel 56' than the previous flange 62.

This second embodiment further reduces the probability of tearing and snagging of the plastic bag at the lower corners. Additional tearing of the plastic bag is minimized by providing the wider continuous flanges 63' of each panel 60' so that the compacted refuse package can easily be extracted from the compactor compression chamber. When the dolly assembly with compacted refuse filled sleeve 24 and plastic bag 25 are being extracted there is a tendency for the panels to spread apart at their lower extremity causing snagging of the bag. With the wider flange 63' this tendency of snagging is greatly minimized.

The dimples construction 54 which secures the rim 52 to the panels and the handles 58 preferably project inwardly into the interior of the sleeve so that only the substantially flat outer surface of the sleeve contacts the inner surface of the bag.

The combination rim and panel construction serves to achieve strength against localized and distributed loading on the rim similar to a beam on an elastic foundation wherein the rim acts like a beam and the panels like an elastic foundation. The reinforcing rim 52 also prevents tearing and destruction of the upper panel edges of the sleeve, and the individual panel compressive strength and stability is increased by the normal to panel pressure induced by the compaction loading, where each panel is sandwiched between the compression chamber walls of the compactor and the refuse because of the lateral loading generated on the refuse being compacted.

The dolly assembly 70 as shown in FIG. 2 serves to provide the transportation means for removing the compacted refuse within the packaging bag and sleeve. The dolly assembly '70 comprises a wheeled dolly body with removable handle means 91. The dolly body can be integrally constructed but preferably comprises a base plate 76, which can optionally include a flange 78 and a vertical front plate 72 secured to the base plate. I The base plate 76 is located at or near the bottom of the compression chamber 32 when the dolly assembly is placed in housing in a vertical compression stroke compacting machine. The base plate 76 may serve as, but is not restricted to, the structural component and lower boundary of the compression chamber in the lower plane as well as the member holding sleeve 24. When the base plate 76 serves as the bottom structural element, it has a greater thickness than when the base plate is backed up by an additional plate which is rigidly secured to the compacting machine to form a portion of the housing 20. If desired, the base plate can rest on brackets which provide structural support for the base plate. The base plate 76 also serves as the lower boundary and support for the dolly assembly 70 when the refuse compacted in the sleeve is to be moved from the compactor.

If desired, the base plate 76 can have dowels 86 protruding from its bottom surface which serve to index and guide the dolly assembly 70 into its proper location in the compression chamber 32 for the compacting mode of operation. The dowels 86 can be positioned in corresponding apertures, slots or notches 88 located in brackets secured to the housing walls or in a base forming the bottom of the compression chamber.

The dolly base plate 76 has a vertical front plate 72 secured thereto by suitable fastening means such as fasteners or welding. As previously mentioned, the base plate and front plate can be integrally constructed, if desired. The height of the front plate is such that it fits in the housing to provide a substantially closed side of the compression chamber.

A flange 46 is preferably integrally constructed with the vertical front plate 72 and extends inward into the compression chamber. The flange 46 bears down on the top of rim 52 of sleeve 24 to restrict the sleeve from shifting or rising up during refuse compacting as the compacted refuse tends to expand vertically when the cylinder plate load is removed from contact with the refuse during the several cycles of compacting and filling the compactor with refuse. The construction of flange 46 allows horizontal arm 44 to be swung open about the vertical hinge line shown on the right side of FIG. 5 even when a fully compacted refuse load has not been reached. At the same time, the tendency of the sleeve to rise above its normally installed height is prevented. Thus, the refuse can be compacted within the compactor at any level up to an elevation level preferably below that of the upper reinforcing rim 52.

In an alternate embodiment of the invention, dowel pins can be inserted through the horizontal arm 44 and secured thereto, to restrict the movement of sleeve 24. The dowel pins take the place of flange 46 and bear 'down on the rim 52 of the sleeve 24 to restrict the sleeve from shifting or rising up during refuse compacting.

Dolly wheels 82 are rotatably mounted to the plate 72 by suitable means such as wheel brackets 84. The dolly wheels 82 and their respective brackets 84 are preferably attached to the lower outboard face of the front plate 72 to provide rolling action and pivot means for the dolly assembly when the dolly is tilted out of the compacting machine and moved away carrying the sleeve package from the compaction machine. A female socket is preferably provided in each dolly wheel bracket 84, or in separate brackets, to position and hold the handle means 91 at its lower extremity. Means are provided relative to the floor or bottom of the compacting machine to unload the wheels during the compacting mode. If desired, the wheels can alternately be mounted to the base plate 76 to provide rolling action for the dolly assembly.

The removable dolly handle means 91 has a frame 92, which is preferably U-shaped and can be fabricated of pipe, tubing, or other suitable structural shape to enable the dolly to be tilted, manipulated, pushed or pulled, in and out of the compaction apparatus. The handle frame 92 is removed from the dolly during the compaction mode and may be clipped to the apparatus or to a wall of the room in which the compaction apparatus is located for storage purposes. The handle frame 92 preferably has horizontal braces in at least two locations and latch means 98 adapted to hold sleeve 24. The upper brace 94 serves as a structural brace for the handle and can support the latch means 98 which engages the sleeve 24. Alternately, the latch means 98 may be secured to the front plate 72 to hold sleeve 24 when the dolly assembly is tilted and removed from the compaction chamber 32.

As shown in FIG. 2, the refuse has been compacted into the sleeve and bag and the refuse removal process begun. The door latch has been released and the door pivoted, causing the door to swing downward approximately 60. The horizontal arm latch means has been operated to release the horizontal arm 44 so that the loading door can swing about pivot 42, freeing the front plate 72 of the dolly assembly.

After the loading door has been swung away, the bandle frame 92 is mounted into the wheel brackets and the latch means 98 on the handle frame or front panel is engaged to the sleeve 24. The handle frame 92 is pulled causing the dolly assembly 70 to pivot and disengage from the housing 20 so that the refuse package and sleeve carried by the dolly assembly can be pulled or pushed to the desired discharge station, the sleeve removed and the refuse package disposed of.

A new bag is then placed around the sleeve 24 and the bag and sleeve are positioned on empty dolly 70. The dolly is then placed into the housing to form the compaction chamber 32 with the bag 25 and sleeve 24 positioned to receive bulk refuse for compaction therein through loading door 38. Thus, the operation cycle repeats.

The upper rim 52 of the sleeve 24 is preferably fabricated of steel, with the sleeve panels 50 fabricated of aluminum. However, the sleeve assembly can be fabricated from other materials, such as plastic and metals, for example, aluminum or a combination of plastic and metals including for example singularly or in combination, metal rims; rigid plastic panels; rigid plastic reinforced rims; rigid plastic panels; semi-rigid plastic reinforced rims; semi-rigid plastic panels.

The use of a semi-rigid plastic sleeve material will minimize the possibility of tearing of the flexible bag being protected by the sleeve. An accordion-type joint between adjacent panels 50 would afford sufficient joint expansion to facilitate removal of the sleeve FIGS. 8-10 disclose this accordion-type joint between panels 56" and 60''. In addition to the accordion joint, the choice of semi-rigid plastic material for the sleeve will minimize the possibility of tearing of the flexible bag by virtue of smoother, less abrasive edges of the sleeve coming into contact with the bag being protected. The specific region or zone improved by the use of semirigid plastic material for the sleeve is at the bottom edge or lower extremity of the sleeve assembly, where the sleeve panels rest on the bottom plane of the dolly assembly forming the compactor compression chamber.

This difference in panel construction in the lower contact area is analogous to the shearing action of a metal edge on the flexible plastic bag bearing on the bottom plane for the metal sleeve panel construction, in contrast with the reduced shearing action of a semirigid plastic edge on the same flexible plastic bag bearing on the bottom plate for the semi-rigid plastic sleeve panel construction.

The size and shape of the compaction chamber or zone 32 and sleeve 24 is not critical so long as they are both generally the same and the sleeve is able to resiliently expand into contact with the walls of the chamber enabling the large lateral forces encountered during the compaction to be absorbed by the walls of the compaction chamber and not the sleeve. This permits a design and construction for the sleeve which is lightweight and easily removable from around the compacted refuse.

Supporting elements or shear pads 55 can additionally be affixed in a suitable combination with the compression chamber side frames, rear panel and dolly front plate to minimize the compression loading near the top edge of the sleeve panels. It is not necessary that the shear pads be affixed to each of the two side frames, the rear panel and the front plate of the dolly, and the addition of these supporting elements or shear pads does not hinder the extraction of the dolly as the dolly assembly is easily tilted even in the presence of the shear pads.

While preferred embodiments of the invention have been disclosed, numerous modifications will occur to those skilled in the art without departing from the inventive concept. Accordingly, it is intended and understood that the invention not be limited to the precise embodiments as disclosed but only as defined by the appended claims.
