Abstract
A refuse collection assembly for a refuse collection vehicle mounts to a intermediate container on the refuse collection vehicle. The refuse receptacle collection assembly can grasp a refuse receptacle at curbside, at street side, or forward of the intermediate container in any location over a one hundred eighty degree arc. The collection assembly grasps the receptacle and locates it above the intermediate container and tilts it sufficiently to empty the contents of the receptacle in the intermediate container. The collection assembly then returns the receptacle upright to its previous location or to any location to the right, left or forward of the refuse collection assembly. The refuse receptacle collection assembly includes a rail extending along a wall of the intermediate container, a carriage selectively movable along the rail, and a receptacle engaging assembly supported by the carriage for grasping the refuse receptacle.

DETAILED DESCRIPTION OF THE INVENTION
(16)
(17) Upon release and opening of tailgate assembly 48, refuse stored and contained within storage body 24 may be unloaded therefrom.
(18) Intake compartment 50 of storage body 24 is preferably positioned forward of storage portion 46 and includes at least one compactor assembly (not shown) for moving refuse from intake compartment 50 into storage body 46 while compacting it.
(19) Dumping assembly 28 lifts and empties contents of intermediate container 26 into storage body 24 and generally includes a pair of lifting arms 60a, 60b which are operated by well known driving devices such as hydraulic cylinders which are controlled by control devices within cab 32 as is conventionally known in the art. Arms 60a, 60b, when in lowered position as seen in
(20) Intermediate container 26 is preferably supported on arms 60a, 60b of dumping assembly 28. To unload refuse from intermediate container 26 into storage body 24, dumping assembly 28 lifts intermediate container 26 above and rearward of cab 32 so as to invert intermediate container 26 above intake compartment 50.
(21) Intermediate container 26 includes frame 68 which supports intermediate container 26 upon arms 60a, 60b. Refuse receptacle collection assembly 30 is supported adjacent intermediate container 26 and is configured for engaging a refuse container located either curbside or street side or at any selected position forward of collection vehicle 20. Carriage 109 of refuse receptacle collection assembly 30 is selectively movable relative to front wall 82 of intermediate container 26 to permit refuse receptacle engagement assembly 137 to reach in any direction, forward of, or at either side of intermediate container 26. Refuse receptacle collection assembly 30 enables an operator within cab 32 to operate the refuse receptacle collection assembly 30 to engage a refuse container, lift the refuse container off the ground, move the refuse container as necessary to sufficiently position the refuse container over intermediate container 26, and to further tilt the engaged refuse container so as to unload the contents of the engaged refuse container into intermediate container 26. As a result, receptacle collection assembly 30 enables the operator to more easily and more efficiently collect refuse contained in refuse receptacles stationed along a roadway or alley, including in cul-de-sac locations.

(24) In the top view of
(25) Referring now particularly to
(26) Further detail of the novel refuse receptacle collection assembly 30 is illustrated by reference to
(27) Rail 103 is fixed to intermediate container 26 and extends along a front side wall 82 of intermediate container 26. Rail 103 extends from street side 22 to curbside 21 of intermediate container 26. Rail 103 may project toward curbside 21 past curbside sidewall 80 of intermediate container 26 as seen in
(28) It is to be understood that attachment of the refuse receptacle collector assembly 30 to front sidewall 82 of intermediate container 26 is only one of the possibilities for mounting of collector assembly 30 on intermediate container 26. Optionally, refuse receptacle collection assembly 30 may be mounted to the rear sidewall 86 of intermediate container 26 provided that frame 68 is expanded to provide sufficient clearance between trunnion 75 and rear sidewall 86.
(29) Because of the narrow width of carriage 109, it is alternatively possible to adapt collection assembly 30 for mounting to curbside sidewall 80 or streetside sidewall 85.
(30) Referring again to
(31) Rotary motor 111 drives pinion gear 115 which mates with rack teeth 107 of rack 105. By operating rotary motor 111 selectively in a clockwise or counterclockwise rotation, carriage 109 may be caused to move along rail 103 to any selected position along the rail 103.
(32) Carriage 109 includes actuator support 117 mounted thereto and actuator support 117 supports rotary actuator 119 which is preferably hydraulically driven and which effects angular rotation of arm assembly 121 about a range of approximately 180 degrees from a position directed curbside 21 to an opposing position directed street side 22. The rotation of rotary actuator 119 is continuous and rotary actuator 119 may be stopped by an operator stationed in the cab 32 at any location within the 180 degree arc.
(33) Rotatably supported on rotary actuator 119 is arm assembly 121 which includes refuse receptacle engagement assembly 137. Arm assembly 121 comprises a boom support 127 which selectively rotates about the substantially vertical axis 120 of actuator 119 when driven by rotary actuator 119. Boom support 127 supports elongate boom 123 which inclines divergingly from the axis 120 of rotary actuator 119.
(34) Pivotally attached to boom 123 at its distal end 129 is elongate arm 131 which interconnects refuse receptacle engagement assembly 137 to boom 123. A tie rod 135 interconnects boom 123 to trip plate 132. It can be seen that arm 131 is pivotable about first axle 133 which fixes arm 131 to distal end 129 of boom 123. Referring particularly to
(35) In the embodiment of
(36) Tie rod 135 joins boom 123 to refuse receptacle engagement assembly 137 at trip plate 132 thereof. Selective orientation of gripper arms 141, 143 and 145 about a generally horizontal position is effected by one or more linear drive mechanisms, preferably hydraulic cylinders which are not visible in
(37) Carriage 109 supports rotary motor 111 upon shelf bracket 138 which also provides a shelf guide 147 which supports cable track 79 seen in
(38) Bumper element 159 is mounted to carriage 109 to absorb abutment impacts of boom support 127 upon carriage 109 when arm assembly 121 is moved by rotary actuator 119 to orientation at street side 22.
(39) Refuse receptacle collector assembly 30 comprises actuator support 117 on which rotary actuator 119 is supported in a substantially vertical orientation so that arm assembly 121 will travel in a substantially horizontal plane. Boom support 127 is fixed to actuator frame 117 and it supports boom 123. A first hydraulic cylinder 161 is interposed between first pin 125 of boom support 127 and second pin 124 of intermediate arm 131 such that intermediate arm 131 may be raised and lowered.
(40) Referring now to
(41) The fully separated position of gripper arms 141, 145 as shown in
(42)
(43) Rail 103 is secured to sliding channel member 205 such that rail 103 extends either toward curbside 21 or street side 22 as it moves with second elongate channel member 205.
(44) Arm assembly 121 is supported moveably along rail 103 and its position along rail 103 is controlled by interaction of pinion gear 115 upon linear toothed rack 105. Refuse receptacle engagement assembly 137 is therefore provided an enlarged range of motion by movement of sliding elongate channel member 205 along mounting channel 203.
(45) Preferably all movements are controlled by hydraulic drive fluid supplied by the vehicle 20 on which alternative refuse receptacle collection assembly 230 is supported. Operation of the drive components of automated refuse receptacle collection assembly 230 is accomplished by controls within the cab 32.

(48)
(49) A second alternative embodiment of the invention is illustrated in
(50)
(51) In operation, refuse collection vehicle 20 enables an operator to quickly and efficiently collect refuse contained in receptacles without extensive manual or physical labor. In particular, by selective control of refuse receptacle collection assembly 30, an operator may collect a refuse receptacle from a multitude of locations with respect to the refuse collection vehicle. For example, by selective movement of carriage 109, the operator may collect refuse receptacles located forward of or at curbside or at street side of intermediate container 26. By selective movement of rotary actuator 119, the operator may direct the refuse receptacle engagement assembly 137 in various directions to collect refuse receptacles located anywhere within the 180 degree range of arm assembly 121. By selectively moving both carriage 109 and arm assembly 121, the operator can collect refuse receptacles at any location within the reach of the arm assembly 121 over the range of 180 degrees forward of front wall 82 of container 26 from curbside 21 to street side 22. Furthermore, by selective movement of arm 131, the operator may collect refuse receptacles supported and stored at different horizontal levels by raising and lowering the refuse receptacle engagement assembly 137.
(52) Once a refuse receptacle has been engaged by refuse receptacle engagement assembly 137, unloading the receptacle into intermediate container 26 is easily completed by selective actuation of carriage 109 and rotary actuator 119. If intermediate container 26 is divided into a plurality of bins 66 as shown in
(53) Once the contents of the refuse receptacle have been unloaded into intermediate container 26, the operator may selectively reposition the empty refuse receptacle at the previous position or at a new position by selective movement of carriage 109 and rotary actuator 119. After the refuse receptacle has been lowered and released by selective actuation of arm assembly 121 and refuse receptacle engagement assembly 137, arm assembly 121 and refuse receptacle engagement assembly 137 may be compactly stored adjacent intermediate container 26 to avoid obstruction of the operator's view while unloading intermediate container 26 into refuse collection vehicle and while driving refuse collection vehicle 20. In particular, gripper arms 141 and 145 may be easily fully retracted for compact storage.
(54) As can be appreciated, refuse collection assembly 30 may be used with a variety of refuse collection vehicles. For example, refuse collection assembly 30 may alternatively be used with a refuse collection vehicle 20 having a single or multiple storage compartments. Refuse receptacle collection assembly 30 may alternatively be mounted to an intermediate container located adjacent a side of the refuse collection vehicle or at a rear of the refuse collection vehicle.
(55) Furthermore, as can be appreciated, refuse collection assembly 30 may have a variety of alternative configurations. For example, refuse receptacle collection assembly 30 may also be oppositely configured for extending around and parallel to street side 22 of intermediate container 26. The arm actuator mechanism 121 may include any one of a variety of well-known equivalent mechanical and structural configurations to provide the same function with the same particular range of motion.
(56) The foregoing description of the invention has been presented for purposes of illustration and description and is not intended to be exhaustive or to limit the invention to the precise form disclosed. Modifications and variations of the embodiments are possible in light of the above disclosure or such may be acquired through practice of the invention. The embodiments illustrated were chosen in order to explain the principles of the invention and its practical application to enable one skilled in the art to utilize the invention in various embodiments and with various modifications as are suited to the particular use contemplated. It is intended that the scope of the invention be defined by the claims appended hereto, and by their equivalents.
