This application claims priority and benefit of the filing date of U.S. patent application No. 15/487,149 filed on 13/4/2017, which is hereby incorporated by reference in its entirety.

Technical Field

The present invention relates to carts for receiving debris from a job site, and systems and methods for handling debris using such carts.

Background

Conventional techniques for handling debris generated at a job site require the debris to be handled by a large number of workers. Typically, roll-on trucks are used to deliver large trash containers to the job site. A large designated area is required for placing, loading and unloading the trash. Thus, the bin is typically held in a fixed position, which is often inconveniently located at a great distance from where the debris is generated or obtained. As a result, debris often accumulates on the ground or floor surface and is later transported to a trash bin. Typically, at least two separate processing operations (debris accumulation, debris transport) are required to place the debris in the bin. The bin typically receives all types of debris from the job site and remains open to allow material to be placed in the bin at any time. Not surprisingly, such bins are often filled with a wide variety of debris types, making it difficult to separate recyclable materials from other materials. Furthermore, since the waste bin is easily accessible to public personnel, the waste bin is often filled with waste material from non-construction sites.

Accordingly, there is a need for improved systems and methods for handling debris generated at a job site. In particular, there is a need for systems and methods that minimize the number of processing operations required to process debris generated at a job site. There is a further need for systems and methods that improve the efficiency, reliability, and/or safety of debris handling.

Disclosure of Invention

In various aspects, a system for processing debris is described herein. The system may have: at least one cart, a lift, and a first conveyance assembly (e.g., an upstream conveyance assembly). Each cart may have: a base, a plurality of wheels extending downwardly from the base relative to a vertical axis, and a plurality of walls extending upwardly from the base. The wall and the base of each cart may cooperate to define a debris receiving space. The lift device may have at least one arm assembly configured to engage a portion of the base of a respective one of the at least one cart when the cart is in a resting position. Upon engagement between the at least one arm assembly and the cart, the at least one arm assembly of the lift device may be selectively rotatable relative to an axis of rotation to move the cart about and between a rest position and an unloaded position. The cart may reach the unloading position after rotational movement of the at least one arm assembly of the lift device along an arcuate path having an arc length in a range of about 130 degrees to about 170 degrees. The first transfer assembly may be configured to receive debris from the at least one cart when the at least one cart is in an unloading position.

The system may also include a plurality of bins configured to receive debris. Each bin may have a base assembly having: a base configurable for selectively moving about and between an open position and a closed position; and an actuator operably coupled to the base and operable to effect selective movement of the base about and between the open and closed positions. Each bin of the plurality of bins may have a plurality of walls coupled to and extending upwardly from the base. The plurality of walls and the base may cooperate to define an interior space. The system may also include a downstream transfer assembly configured to deliver debris toward the plurality of bins. The downstream transfer assembly may have a top surface positioned in communication with at least one wall of each bin of the plurality of bins to facilitate delivery of debris into the interior space of each bin. The base of each bin may be configured to distribute debris from the interior space of the bin through the base as the base moves from the closed position toward the open position.

In further aspects, a method for processing debris is also described herein. The method can comprise the following steps: providing at least one cart to a job site; transporting the at least one cart from the job site to a debris handling facility; and effecting engagement between the at least one arm assembly of the lifting device and a first of the at least one carts. Each cart may have: a base, a plurality of wheels extending downwardly from the base relative to a vertical axis, and a plurality of walls extending upwardly from the base. The wall and the base of each cart may cooperate to define a debris receiving space. The debris handling facility may include a lifting device and a first transfer assembly. After engagement between the at least one arm assembly and the first cart, the method may include: selectively rotating the at least one arm assembly of the lift device relative to an axis of rotation to move the first cart from a resting position to an unloading position. The first cart may reach the unloading position after rotational movement of the at least one arm assembly of the lift device along an arcuate path having an arc length in a range of about 130 degrees to about 170 degrees. The first transfer assembly may receive debris exiting the first cart with the first cart in the unloading position. The first (e.g., upstream conveyor assembly) may then deliver the scrap onto a downstream conveyor assembly, which in turn may transport the scrap to a location corresponding to (e.g., aligned with or in communication with) at least one bin of the plurality of bins of the conveyor assembly such that the scrap may be moved into the at least one bin of the plurality of bins. Once each bin of the at least one bin includes a desired amount of debris, an actuator associated with the base assembly of each bin may be activated to effect movement of the base of the bin from a closed position toward an open position. With the base in the open position, debris from the at least one bin may be unloaded into at least one container positioned below the at least one bin.

In a further aspect, described herein is a debris cart having: the base assembly includes a base, a plurality of wheels extending downwardly from the base relative to a vertical axis, a plurality of walls extending upwardly from the base of the base assembly, and a plurality of receptacles extending downwardly from the base. The plurality of walls cooperate with the base to define a debris receiving space. The plurality of walls may include: opposing front and rear walls and opposing first and second side walls. The first and second side walls extend between and are connected to the front and rear walls. Each of the plurality of walls has a rounded upper edge. The front and rear walls have respective outer surfaces. Moving from the respective rounded upper edges of the front and rear walls toward the base, the outer surfaces of the front and rear walls taper axially with respect to the vertical axis at a first taper angle. The first and second sidewalls have respective outer surfaces. Moving from the rounded upper edge of each sidewall toward the base, the outer surfaces of the first and second sidewalls taper axially at a second taper angle relative to the vertical axis. The plurality of receiving parts may include: a first set of receptacles having at least one row of receptacles aligned relative to a longitudinal axis extending through the opposing first and second sidewalls of the cart; and a second set of receptacles having at least one row of receptacles aligned relative to a transverse axis extending through the opposing walls of the cart.

Additional advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The advantages of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the application.

36, 42 with swivel casters, as further disclosed herein.

As shown in fig. 1-6, each debris cart 10 may include a plurality of receptacles extending downwardly from the base 20. It is contemplated that the receptacle may optionally have a rectangular or substantially rectangular shape; however, it is contemplated that any shape complementary to the lifting device (e.g., circular shape) may be used. Optionally, in an exemplary aspect, the plurality of receptacles may include a first set of

receptacles

80a, 80b having at least one row of receptacles aligned relative to a longitudinal axis 4, the longitudinal axis 4 extending through the opposing first and

second side walls

36, 42 of the cart and perpendicular to the vertical axis 2. Optionally, in these aspects, it is contemplated that the plurality of receptacles may also include a second set of receptacles 82a, 82b having at least one row of receptacles aligned with respect to a transverse axis 16, the transverse axis 16 extending through the opposing front and

rear walls

22, 30 and perpendicular to the vertical axis 2 and the longitudinal axis 4. As shown in fig. 6, it is contemplated that each set of receptacles may include a plurality of aligned rows of receptacles.

In further exemplary aspects, it is contemplated that the cart 10 may include at least one floor latch 90, such as a conventional floor latch brake known in the art. In these aspects, it is contemplated that the floor latch 90 may extend downward from the base 20 and be configured to be selectively engaged by a worker (e.g., a foot of the worker) to actuate the floor latch. In an exemplary aspect, as shown in fig. 6, it is contemplated that the floor latch 90 may be positioned between (optionally centered on) a pair of wheels 70 (e.g., casters) on one side of the cart 10. Optionally, in these aspects, it is contemplated that the wheels 70 may include a pair of swivel casters positioned on the same side of the cart as the ground lock 90, allowing for optimal control of the cart.

In still further exemplary aspects, the cart 10 can include a plurality of folding (e.g., hinged) handles 95 secured to at least one

side wall

36, 42 of the cart. In these aspects, it is contemplated that the folding handle 95 may allow for manual control of movement of the cart 10, while folding of the handle ensures that the cart has a reduced profile during transport and stacking (e.g., in confined spaces). Optionally, a handle 95 may be secured to both

sidewalls

36, 42.

In other exemplary aspects, each cart can be assigned a unique identifier and provided with indicia of the unique identifier. Exemplary forms of indicia include bar codes, Radio Frequency Identification (RFID) tags, sensors, and the like. In use, it is contemplated that these forms of indicia may be used to track the location of a particular cart 10 and provide a system controller 160 with the ability to associate information with the unique identifier of the cart as further disclosed herein.

Optionally, in exemplary aspects, it is contemplated that the cart 10 may be constructed entirely of steel, thereby limiting and/or preventing side bulging and mechanical failure. In further exemplary aspects, it is contemplated that the walls of the cart 10 may be seemingly welded to prevent and/or minimize the escape of liquid from the debris-receiving space 50.

In further aspects, and with reference to fig. 8A-8C, the system 100 can further include a lift device 120 having at least one arm assembly configured to engage a portion of the base 20 of a respective cart 10 of the at least one cart when the carts are in a rest position. Optionally, in these aspects, the expected resting position may correspond to a position in which the wheels 70 of the cart 10 rest on a flat surface. Upon engagement between the at least one arm assembly and the cart 10, the at least one arm assembly of the lift device 120 may be selectively rotatable relative to the axis of rotation 123 to move the cart about and between the rest and unload positions. In an exemplary aspect, the lift 120 can include an axle 124 through which the axis of rotation 123 passes. As shown in fig. 8A, the cart 10 can reach the unloading position after rotational movement of the at least one arm assembly of the lift device 120 along an arcuate path having an arc length 130 in the range of about 105 degrees to about 175 degrees, and more preferably about 130 degrees to about 170 degrees.

In an exemplary aspect, the lift device 120 can include an actuator coupled to at least one arm assembly of the lift device. In these aspects, the actuator may be configured to enable selective rotational movement of at least one arm assembly of the lift device 120. It is contemplated that the actuator may be any conventional actuator capable of producing rotational movement of the lift 120. In an exemplary aspect, it is contemplated that the actuator may be a hydraulic actuator; however, it is contemplated that other rotary actuators (e.g., pneumatic, mechanical, or electromechanical actuators) may be used.

Optionally, as shown in fig. 11, contemplated systems may include a housing 250 at least partially enclosing or surrounding the lift 120. Optionally, the housing 250 can include at least one wall (e.g., a plurality of walls) surrounding at least a portion of the area in which the cart is effectively rotationally moved. In these aspects, the enclosure 250 may improve the safety of the unloading operation by isolating the system operator from the active unloading area. In an exemplary aspect, the housing 250 can define a lift gate 252, as further disclosed herein. In these aspects, the lift gate may receive each cart prior to unloading. It is contemplated that the opening, closing, and locking of the lift gate may be selectively controlled as disclosed herein by a system controller communicatively coupled to an actuator (e.g., a linear actuator, such as a hydraulic, pneumatic, mechanical, or electromechanical actuator) configured to selectively move the lift gate about and between the open and closed positions. As further disclosed herein, the lift gate may be closed (and locked) to limit accidental entry of additional carts until processing of a particular cart is completed. Optionally, the housing can include a constraining wall extending along at least a portion of the length of the transfer assembly disclosed herein.

In further exemplary aspects, and with reference to fig. 8A-8C, each arm assembly of the lift device 120 can include: an arm 122 that may be fixed or otherwise coupled to the axle 124, and at least one engagement element 128 coupled to the arm and configured to engage the base 20 of the cart 10. Optionally, in these aspects, it is contemplated that each

receptacle

80a, 80b, 82a, 82b of the cart can be configured to receive a corresponding engagement element 128 of the lifting device 120. It is further contemplated that the at least one engagement element 128 may be configured to engage the first or second set of

receptacles

80a, 80b, 82a, 82b of each cart 10 depending on the orientation of the cart. Thus, it is contemplated that the cart may engage the arm assembly in any orientation (with the front or rear wall facing the arm assembly, or one of the side walls facing the arm assembly). In use, each engagement element 128 may extend at least partially within each receptacle of the corresponding set of receptacles. Upon activation of the lift, the arm assembly rotates relative to the arcuate path. As shown in fig. 8A, the engagement element 128 and the base 20 of the cart 10 are initially positioned in a horizontal (0 degree) orientation. However, after the lifting device is moved to the unloading position, the engagement element 128 and the base 20 of the cart 10 are positioned at an obtuse angle (corresponding to the arc length 128) relative to the ground, with the inner surface of the base 20 (and the debris receiving space 50) facing the ground, thereby allowing the debris to be unloaded from the cart with the aid of gravity.

In an exemplary aspect, the at least one engagement element 128 of each arm assembly is pivotably coupled to the arm 122 of the arm assembly. Fig. 8B depicts an exemplary pivot point 125 at which the at least one engagement element 128 is pivotably coupled to the arm 122. Optionally, in these aspects, the arm assembly can further include a mount 126, the at least one engagement element 128 being fixed (e.g., mounted) to the mount 126, and the mount can be pivotally coupled to the arm 122 at a pivot point 125, thereby pivotally coupling the at least one engagement element to the arm. The pivot point 125 may include a conventional pivot connection such as, for example, but not limited to, a pin connection. In use, it is contemplated that the pivotal connection (at the pivot point 125) may allow for adjustment of the position of the at least one engagement element 128 to provide optimal positioning of the engagement element relative to the cart 10. For example, it is contemplated that the mount 126 (and the engagement member 128) can be rotated at the pivot point 125 to adjust the vertical position of the engagement member. In still further aspects, the arm 122 can optionally include a plurality of openings or slots spaced along the length of the arm, wherein each opening (or set of aligned openings) is configured to receive a pin, thereby allowing the position of the pivot point 125 to be adjusted (by allowing the mount 126 to be pivotally coupled at various positions relative to the length of the arm). Optionally, in further aspects, it is contemplated that the at least one engagement element 128 can be configured for selective axial movement relative to the axis of rotation 123. In these aspects, it is contemplated that the arm 122 may be slidably coupled to the pin to allow axial movement of the arm 122 (and thus, the mount 126 and the engagement element 128) relative to the axis of rotation 123. Alternatively, it is contemplated that the mount 126 may be slidably coupled to a pin fixed at the distal end of the arm 122 to allow for axial movement of the mount (and, therefore, the engagement element 128) relative to the axis of rotation.

In these aspects, it is contemplated that the user interface 208 may include switches, buttons, a touch screen, toggle switches, a keypad, a joystick, or a combination thereof. Thus, rather than using the weight measuring device 200 or the plurality of sensors 210 to automatically detect when a desired amount of debris is present within each respective bin, it is contemplated that the system operator may provide input directly into the user interface to effect actuation of the indicator, such as when the system operator observes the bin (and optionally analyzes the output from the weight measuring device and other sensors) and determines that the desired amount of debris is present in the bin.

In the foregoing and following description, various components of the system are described as being communicatively coupled to (or otherwise positioned in communication with) each other. As used herein, this term is intended to encompass both a direct wireless connection or a wired connection, as well as an indirect wireless connection or a wired connection through a system controller (or other component of the system).

As further described herein, the downstream transport assembly may receive debris from a first cart of the plurality of carts. It is contemplated that the upstream conveyor may receive debris exiting a first cart of the plurality of carts. It is further contemplated that the upstream conveyor may carry debris toward the downstream conveyor. Once the downstream conveyor receives the debris from the upstream conveyor, the downstream conveyor may transport the debris toward a plurality of bins. In this regard, debris from a first cart of the plurality of carts can be selectively sorted or distributed into a plurality of bins as desired using manual or automated means. In these aspects, this process is repeated until debris from the last cart of the plurality of associated carts is dispensed into the plurality of bins. If desired, the weight of each bin may then be measured, and the total weight of debris in a plurality of bins may be determined.

In further exemplary aspects, as shown in fig. 9, it is contemplated that the system controller 160 may be communicatively coupled (optionally wirelessly, such as via the internet or a cellular communication network) to various components of the system 100 to receive information and/or control the performance of the system. For example, it is contemplated that the system controller 160 may be communicatively coupled to the

remote scanners

104, 106 to receive information about the cart (such as the cart's location, identification, or characteristics/features of the cart) as it is delivered to or returned from the job site. It is further contemplated that the system controller 160 may be communicatively coupled to the scale 115 to receive information from the scale regarding the weight of the cart. In an exemplary aspect, the disclosed method may include: information regarding the weight of the first cart is transmitted to a system controller as disclosed herein. In these aspects, the method may further comprise: a system controller is used to associate a measured weight of a first cart with a unique identifier assigned to the cart. It is contemplated that the system controller may associate the measured weight and other information about a particular cart with a corresponding cart identifier in data (e.g., a data table) stored in memory, as further disclosed herein. It is contemplated that system controller 160 may be communicatively coupled to camera 118 and/or camera 145 to receive images obtained by the camera and/or to control activation of the camera during processing of debris, as disclosed herein. In an exemplary aspect, the disclosed method may include: an image of the cart and/or debris provided to the first transport assembly from the first cart is generated. In these aspects, the method may further comprise: an image of the cart and/or an image of debris is transmitted to the system controller. The method may further comprise: the system controller is used to associate the image of the cart and/or the image of debris with the unique identifier assigned to the cart (and, optionally, store the image with other data associated with the unique identifier of the cart). It is further contemplated that the system controller 160 may be communicatively coupled to the actuators of the lift 120, as disclosed herein. Optionally, the system controller 160 can selectively control rotation of the lift 120 to control movement of each cart about and between the rest and unload positions. Similarly, it is further contemplated that the system controller 160 may be communicatively coupled to the first transfer assembly 140 and/or the second transfer assembly 150. Optionally, the system controller 160 can selectively control the speed of one or both of the first and

second transfer assemblies

140, 150. It is contemplated that system controller 160 may be communicatively coupled to an actuator of at least one bin of the plurality of bins, as further disclosed herein. Optionally, the system controller is communicatively coupled to a plurality of sensors positioned proximate each bin to receive an output indicative of a desired amount of debris within the respective bin. In an exemplary aspect, the disclosed method may include: transmitting information regarding the weight of the at least one bin to a system controller as disclosed herein. It is further contemplated that the system controller may be communicatively coupled to the indicator to receive an alert related to an amount (e.g., height) of debris within the bin.

In use, and as further disclosed herein, it is contemplated that the memory 164 of the system controller 160 can store data and other information obtained during debris handling, as disclosed herein. Such data may be retrieved as needed to generate invoices, reports, and other deliverables related to debris collected in a cart or group of carts, as disclosed herein. Optionally, in exemplary aspects, the system controller 160 can transmit the debris processing data to a central computing device or server communicatively coupled to the system controller, and the transmitted data can then be retrieved from the central computing device or server (optionally, from a remote location using the internet or a network connection) for further downstream use and/or analysis. In an exemplary aspect, data and other information provided to a central computing device or central server may be used to generate invoices, reports, and other deliverables related to debris collected in a cart or group of associated carts, as disclosed herein. Optionally, such a central computing device may have a processing unit configured to automatically generate such invoices, reports, and/or other deliverables based on data received from the system controller or other system components. Alternatively, in other aspects, the above-described capabilities of the central computing device may be implemented by the system controller 160 itself (without the need for a central computing device or central server). Thus, in these aspects, the system controller 160 may allow for the retrieval of debris handling data (e.g., data associated with a particular cart identifier or a plurality of associated cart identifiers) for downstream use and/or analysis, including the generation of invoices, reports, and other deliverables, as disclosed herein. Optionally, the processor of the system controller 160 may be configured to automatically generate such invoices, reports, and/or other deliverables based on data stored in the memory of the system controller. As one example, system controller 160 may generate or allow retrieval of information necessary to generate invoices or reports regarding a plurality of associated carts (such as carts used at a particular job site during a particular job).

Thus, in use, it is contemplated that the disclosed systems and methods may provide various advantages over conventional debris handling techniques. For example, it is contemplated that the disclosed systems and methods may be used to deliver carts to a job site via a straight truck with a conventional lift gate, rather than the roll-on mechanism typically required to place trash. It is further contemplated that the disclosed systems and methods may eliminate the need for a large design area for loading and placing the trash. Instead, the cart may be delivered to various locations throughout the job site, and after delivery, the cart may be selectively spread (rolled) throughout the job site with minimal effort as needed. In contrast to conventional practice, the disclosed systems and methods allow debris to be placed directly into the cart regardless of the location of the debris within the construction site, thereby eliminating the need for stacking and "double handling" of the debris. After the debris is collected in the cart, it is desirable to roll the cart directly to a truck for transport — without transferring the material from the cart to a trash bin. Due to the flexibility provided by the cart, it is contemplated that the cart retrieval point (where the truck picks up the cart) may be different from the cart delivery point (where the cart is initially delivered to the job site). It is further contemplated that each cart may be designed for a particular material, resulting in higher recovery; in contrast, current technology typically requires that all materials be placed in a common trash bin. In view of the ease with which the disclosed carts can be selectively positioned, it is contemplated that the disclosed systems and methods may provide greater control over access to the carts, thereby enhancing the safety of the contents of the carts while limiting or preventing the placement of non-job site waste into the carts. It is still further contemplated that the tracking and monitoring system disclosed herein may be used to track a particular source of discarded debris in situations where the cart has been distributed between specialized job sites.

Exemplary procedure

The following description relates to exemplary, non-limiting processes consistent with the disclosed systems and methods.

Example one

Initially, at least one cart may be ordered for a particular job site. An invoice may be created using a unique ticket number. Each cart is provided with indicia associating the cart with a ticket number. A desired number of carts may be scanned and assigned to a job site location. The cart may then be delivered to the job site. After delivery, the cart may be rolled to a desired work area at the job site. The debris can be placed into the cart. As described herein, the cart may optionally be designated for a particular material for performing source separation to improve recovery. All carts may be rolled to a loading dock or other area for pickup, which may occur at a location different from the location of unloading. At the time of pickup, the indicia (bar code/RFID) associated with each cart may be scanned for job site identification and inventory tracking. The filled cart may then be taken to a recycling facility. The cart may be rolled from the truck onto a platform and placed in a queue for processing. Each cart may be moved onto a scale positioned proximate to the elevator. The lifting device may include a hydraulic actuator arm having a fork mechanism. Immediately before the cart lift mechanism begins operation, the cart's bar code/RFID is scanned, the cart is weighed, and the cart is photographed. The forks lift the cart in an arcuate path corresponding to an arc length of about 160 degrees. The debris/material falls (by gravity) from the cart onto the feeder conveyor. The feeder conveyor measures the material arriving on the sorting conveyor line. The cart can be brought back to the platform and manually removed from the forks. The process may be repeated for each cart. The empty cart is available for reuse. On the feeder conveyor, the scrap/material may be photographed to record the contents of each cart prior to sorting. The recorded data may be combined with bar code/RFID and job site location information. Mechanical sorting and/or manual sorting of the debris may be performed. The material may be selected based on current market conditions of recyclability and value. The recorded data can then be used to invoice and generate a recovery report.

Example two

Initially, the driver may scan each cart as it is loaded into the truck at the customer location. The truck may be weighed when it reaches the debris handling facility. The net weight can be automatically calculated from the tare weights of the vehicle and the cart. The net weight may be used for billing purposes. The truck may then be unloaded at the temporary stacking station. The carts may be grouped by ticket or truck, as described herein.

To initiate the process, the system controller may perform a system check at startup. The operator may then select the first cart from a group (or tickets) to be weighed, open the lift gate, and then push the cart into the lift. Scanners may be located on both sides of the elevator doorway to scan the cart while in motion. The photo eye sensor may be used to activate the scanner. Once the first cart is positioned within the lift, the operator may close the door, and the lift door may be automatically locked. Once the door is locked, a light on the lift door is activated, indicating that the door has been successfully locked. The scale may then be triggered to retrieve the gross weight of the cart. If there is gross weight and no scanning occurs (i.e., no bar code is read), a form may be displayed on the display device to allow the operator to manually enter the cart number. If all carts in the group are downloaded to the system controller and displayed on the touch screen, a successful scan has been achieved. Once the door is locked, the elevator may be started. The cart may then be marked as completed on the touch screen of the display device.

The contents of the cart (i.e., the debris) can be unloaded onto the upper conveyor assembly. Once the contents are unloaded, at least one image of the contents may be taken. One or more proximity sensors may be used to activate the camera. After the images are taken, the contents may then be sorted into bins (e.g., twelve bins). The process may be repeated until all carts in the group have been weighed. The controller may detect the last cart in the group, which may cause the controller to begin monitoring the movement of the belt. Sufficient distance may be provided for debris from the last cart to reach the end of the downstream conveyor assembly. Once the contents of all carts have been dispensed into the bin, the bin weight can be taken and then the scale set to zero. The system controller may store the gross weight of the cart, the images of the plurality of bins, and the weight in a database (e.g., SQL database) that may be designed by the customer. The lift gate may remain locked until weighing of an associated group of carts is completed to inhibit processing of the next group. After the weighing of all associated carts is completed, the central controller may be configured to allow the lift gate to be opened.

A sorting line operator may be positioned along the downstream transport assembly. When a bin assigned to the sorting line operator is full, the sorting line operator may request emptying of the bin by pressing a button. The button may include a light source that is activatable when the button is depressed. The system may include a second light in communication with the button and positioned below each bin. When the button is pressed (i.e., depressed), the second light is activated, thereby alerting ground crew to empty the bin. A forklift operator may have a mobile device with a customized software application. The customized software application may display bins that need to be emptied. A forklift operator may move the container under the respective bin and press a button on the moving apparatus to activate an actuator to effect movement of the base from the closed position towards the open position. When emptying the bin, operation of the elevator and upstream and downstream transport assemblies may be stopped until the base is returned to the closed position. If the sorting line operator requests that the bins be emptied in the middle of a group, the system controller may store a partial weight for that group. The scale may be set to zero before the base is returned to the closed position.

During the described process, the goods assigned to the feeder boxes may be changed between groups and after emptying the boxes.

If the cart is too heavy to lift or the cart is damaged, the system controller may be programmed with an "unfinished" button. This can discard the gross weight of the cart and allow the group to be unfinished. Alternatively, the maximum weight for the elevator may be identified, bins and merchandise may be displayed, and the operator may select which bin will receive the net weight from the elevator scale.

As disclosed herein, a system controller may be provided in communication with the user interface, which allows a system operator to control the operation of the system through the system controller. In an exemplary aspect, the system controller may receive user input initiating a "re-dump" procedure that may be used if any material remains in the cart after an initial cycle of lifting the cart and emptied debris onto the upstream transport assembly. Optionally, when the "re-dump" procedure begins, the elevator may shake the cart (e.g., by moving back and forth and/or vibrating force) before or after the cart is inverted, so that any remaining debris slides off the cart and falls onto the conveyor assembly. In exemplary aspects, it is contemplated that this rocking feature may be incorporated into all cart lifting and unloading sequences using a lift so that the lift can rock each cart as part of a standard debris unloading process.
