Field of Embodiments
The disclosed embodiments relate generally to an apparatus and methods for loading and sorting material.
Description of Related Art
Material is often loaded into motor vehicles to be transported to other locations, for example, for delivery, recycling or destruction. A typical motor vehicle used to transport material includes a bin tipper and one common storage area. Typically, the bin tipper will lift a material-filled bin to a position over the top of the common storage area, and subsequently tip the bin such that the material falls out of the bin and into the storage area. The bin tipper can be single or double wide.
A problem encountered by conventional motor vehicles used to transport material is the inability to obtain a level load of the material across the entire storage area. The bin tipper may be disposed at one location the side, front, or back of the motor vehicle body and will repeatedly load material on the motor vehicle at that location in the storage areas. As a result, a pile of the material will be created at that location. Due to the steep angle of repose of the material, the pile tends to peak. When this is coupled with a limited bin dump height and limited overall body height, the volume of material that can be loaded into the vehicle body is limited. In addition, there is typically a lot of void space at or near the vehicle body walls.
In addition, conventional motor vehicles do not allow the operator to segregate materials. All the materials are mixed together in the storage area of the motor vehicle.
A need exists for improved technology, including technology that may address one or more of the above described disadvantages.
One embodiment of the invention relates to a motor vehicle for collecting and sorting material. The motor vehicle includes at least one material-storage compartment of the motor vehicle, a bin tipper configured to receive a collection bin containing the material and a hopper configured to receive the material from the collection bin and transport the material to a selected location in the material-storage compartment of the motor vehicle. The material can be transported to a plurality of locations in the material storage compartment.
Another embodiment of the invention relates to a method for collecting and sorting material. The method includes receiving a collection bin containing the material, feeding the material, with a bin tipper, from the collection bin to a hopper, transporting the material to a selected location of at least two locations in a compartment of a motor vehicle such that the material may be sorted into at least two groups, and discharging the material from the hopper to the selected location.

The material to be loaded and sorted often will contain information and will be recyclable, but the invention can be applied to other materials that do not contain information and/or are not recyclable.
Overview of Motor Vehicle with Transit Loading Apparatus
In general, the transit loading apparatus can be configured to load material from, for example, ground level or dock level and distribute the material into the material-storage compartment and, more preferably, into several receiving containers in the material-storage compartment. More specifically, material may be collected from various sources and provided to the transit loading apparatus in any of a variety of collection bins, such as wheeled containers, carts or other bins. A bin tipper can be used to lift the conveyance device and load the material into a hopper of the transit loading apparatus. The hopper then moves to transfer the material to a pre-selected location or a pre-selected receiving container in the material-storage compartment. The hopper preferably is rotated to align with a container pre-selected by an operator, and the hopper empties the material at the location or into the receiving container, preferably through a moveable door of the hopper. Consequently, material can be loaded and sorted into one of a plurality of locations or containers in the material-storage compartment according to material type, quality or any other desired criteria.
Motor Vehicle
Preferably the motor vehicle 200 is a truck. However, other types of motor vehicles could be used. Moreover, the transit loading apparatus could find advantageous use in circumstances that do not involve the use of a motor vehicle. In one preferred embodiment, the motor vehicle 200 can be a side load collection truck (see
The motor vehicle 200 can include a control system 300 having at least one set of controls 301 that can be manipulated by an operator to control the system (see
More detailed aspects of preferred embodiments of the motor vehicle 200 are described below.
Storage Area
The motor vehicle 200 may include a storage area 30 in the front of the motor vehicle body (see
Bulkhead Door
For security purposes and to prevent egress of confidential materials while the motor vehicle 200 is in transit, the motor vehicle 200 may include a hydraulically actuated sliding bulkhead door 40 configured to seal off the storage area 30 when not in use (see
Material-Storage Compartment
As seen in the preferred embodiment of
In a preferred embodiment, the containers 13 are located in the material-storage compartment 201 of the motor vehicle 200 (see
The containers 13 may be any predefined size, for example, 450 gallon bins. Preferably, the transit loading apparatus includes containers 13 that fit standard lifting/tipping mechanisms for material feed in in-plant shredding systems.
In one embodiment, the containers 13 are restrained in the material-storage compartment 201 in a tight (i.e., no gaps between adjacent containers 13) and predetermined configuration. This ensures that the material is emptied in the desired spot and no material falls between containers. In another embodiment, a part containerized, part bulk loading configuration can be used where, for example, a small quantity of a particular material is collected in a container 13, while the remaining materials are emptied onto the floor of the material-storage compartment 201.
With the inclusion of a plurality of containers 13, the transit loading apparatus 100 can minimize the negative effects of material angle of repose on fill capacity. In addition, the transit loading apparatus 100 has the ability to segregate different types of material. The ability to fill each of the containers 13 containers independently, provides a great deal of flexibility in the type and quantity of materials collected.
After the motor vehicle 200 arrives at its destination, the containers 13 can be unloaded by forklift removal. The containers 13 can include two openings 32 disposed near the bottom of each of the four side faces of the containers 13. The two openings 32 are disposed beneath a floor of the containers 13 to prevent egress of the material from containers 13. The two openings 32 are configured to receive two forks of a conventional forklift.
In another embodiment, the containers 13 can be moved to the back of the motor vehicle 200 by a moving floor system. A conventional moving floor, as is known in the industry, could be disposed on the floor of the material-storage compartment 201 of the motor vehicle 200.
Transit Loading Apparatus
As shown in
Bin Tipper
Bin tipper 2 is configured to load material into the hopper 3. In particular, the bin tipper 2 receives the collection bin 1, lifts the collection bin 1, and empties the contents of the collection bin 1 into the hopper 3 (see
The bin tipper 2 may be housed in a bin tunnel 21 (see
Referring to
Hopper
The hopper 3 is configured to load the material into a desired location in the material-storage compartment 201, such as within a specific container 13 in the material-storage compartment 201. The hopper 3 can be mounted on a hopper mounting frame 15, which is rotatably connected to a hopper mount 14. Hopper mount 14 is supported by four linear bearings 9, which are mounted to two vertical rails 5, which guide the hopper 3 in a vertical direction. As seen in
In a first embodiment, illustrated in
In a second embodiment, illustrated in
In the second embodiment, the hopper 3 does not include a chute 3B that extends from the hopper, the hopper 3 may have a wider range of rotation in order to access each of the plurality of containers 13. For example, the hopper 3 may be configured to rotate up to 93° in a single direction about a vertical axis perpendicular to the hopper mount 14. In such a configuration, if the hopper 3 is not rotated, the hopper 3 may only discharge material into containers 13 arranged on the passenger side of the motor vehicle 200. If the hopper 3 is rotated approximately 93°, the hopper 3 may discharge material into containers 13 arranged on the driver side of the motor vehicle. In addition, in the second embodiment, when the hopper 3 is moved about the material-storage compartment 201 of the motor vehicle 200, a lower leading edge of the hopper 3 is located just above the plurality of containers 13 since the configuration does not include the chute 3B. Thus, the second embodiment minimizes the vertical height and space requirements of the hopper 3.
In both the first and second embodiments, the hopper frame 15 can be vibration isolated from hopper 3 by a rubber mount (not illustrated). A vibrating motor 17 is mounted to the bottom of hopper 3 and is configured to provide force excitation to aid material discharge.
Operation of the Transit Loading Apparatus
Referring now to
A hose and cable carrier 4 houses all hydraulic hoses, electrical wire and sensor wires for vertical motion. Vertical bars 5, which support the hopper 3, are affixed to carriage 7. Carriage 7 is supported by the four linear bearings 9, which are mounted to two horizontal rails 11 (see
An operator can pre-select a container 13 using control system 300 (described in detail below). The process of emptying the hopper 3 can be automated. As illustrated in
The vertical and horizontal rails and bearing elements ensure a smooth transfer and a jerk free movement.
In the first embodiment of the hopper 3, once the hopper 3 reaches the location of the pre-selected container 13 (see
A sensor, not illustrated in the figures, is located under the hopper at the resting position where hopper 3 is positioned to receive material from bin tipper 2. When hopper 3 is in transit away from the resting location, bin tipper 2 is permitted to operate. However, bin tipper 2 will pause and wait at the top of the bin tipper travel (e.g. at the arc) until hopper 3 has returned to the resting position.
Power
In one embodiment, the transit loading apparatus 100 is driven using traditional hydraulic technology through a power take-off (PTO) mounted on the truck transmission, a technique typical of the industry. In another embodiment, the system could be powered using electrical power as outlined in U.S. Patent Application No. 2011/0240777, the entire contents of which is hereby incorporated by reference. Using electrical power provides advantages such as reduced fuel usage and environmental impact on the environment, use of a high percentage of grid energy for operation, operation without the engine idling, and the ability to operate inside buildings without the concern of releasing toxins in the air.
Alternatively, since the overall power requirements of the transit loading apparatus 100 are vey low, a small auxiliary engine power unit, either electric or hydraulic, could be used for power. This would allow for segregation of fuel usage.
Control System
Referring to
The operator can view the load in each container 13 via digital cameras and a video screen on the control system 300 to determine the level of fill and to select the container 13 to receive contents of the hopper 3. Thus, the operator is provided with the opportunity to optimize the fill of the vehicle. The desired location for the hopper 3 is selected manually by the operator via the control system screen and buttons, not illustrated in the figures. The system is programmed such that it will move the hopper 3 to selected location and empty the contents of the hopper 3 in the selected container 13 without further interruption from the operator.
Alternative Embodiments
While the invention is particularly advantageous with the use of containers, advantages also could be realized without the use of containers. For example, there may be only one large receptacle and the hopper 3 could be used to distribute the material within the one receptacle. In such an embodiment, the hopper 3 can empty the material on the floor with no containers 13. In this case, the operator should select the available dumping location in a sequential manner to ensure uniform material distribution of the material and ensure that the material remains at a lower level than the hopper 3 of the transit loading apparatus 100. Sequential distribution will also ensure that the rear of the motor vehicle 200 is not overloaded.
In other embodiments, the movement of the hopper 3 can be varied. For example, the hopper 3 could follow transitional movements instead of pivoting.
