DETAILED DESCRIPTION

Overview

(10) Fulfillment centers may be used to fulfill online purchases and other orders. For example, fulfillment centers may include product inventory that may be pulled when an order for a particular product or multiple products is placed. In some instances, the product(s) may be packed and shipped from the fulfillment center. However, the process of obtaining the product(s), packing the product(s), and shipping the product(s) may be complicated due to the amount of inventory, the number of orders to process, the size of the fulfillment center, and/or other factors. In addition, a portion of the fulfillment center designated for packing or shipping may be different than the portion of the fulfillment center designated for holding product inventory. As a result, transportation of products in an order may be time consuming.

(11) Moving items or objects through a fulfillment center may require handling of the item itself. For example, picking the item from inventory, placing the item into a container, removing the item from a container, and so forth may all be examples of actions for which an item may need to be handled. In addition, different items may have different types of packaging. For example, some items may come in boxes, some items may come in loose bags, some items may come shrink wrapped, some items may not have any packaging, and so forth. Humans may be able to manually handle individual items with ease. However, robotic handling of individual items may require various levels of dexterity. Moreover, fulfillment centers may include lengthy conveyors that may be used to transport objects, such as packages, products, items, or other objects, as well as containers that may be at least partially full of objects. Transport of containers or items (e.g., individual items or multiple items, etc.) may involve the use of container shuttles that move on one or more rails to transport a container from one location to another. For example, a container of items may be loaded onto a shuttle, and the shuttle may transport the container from an inventory field to a sortation system or other location. Shuttles may be used to transport containers and/or one or more items from a first location to a second location.

(12) In a typical warehouse environment, such as that illustrated in FIG. 1, items may be transported through various means such as conveyors, belts, shuttles, etc. as they undergo different operations like picking, sorting, storing, shipping/dispatch, and so forth. In some of these cases, containers may be used to transport items, either individually or in groups, from one location to another. For instance, transporting items from a pick station to a sort station may involve the item(s) being picked into a container, such as a tote, which may then be transported via a shuttle.

(13) Container shuttles may be in continuous operation and may move at relatively high speeds, such as speeds of three meters per second or more. As a result, container shuttles may require scheduled or unscheduled maintenance from time to time. For example, container shuttles may require preventative maintenance at scheduled intervals, such as calibration of one or more components, or may require unscheduled maintenance in the event of a breakdown, etc. In instances where a container shuttle breaks down or experiences a malfunction that causes the shuttle to be unable to move, backups and traffic jams may occur due to the serial nature of shuttle rail tracks.

(14) Accordingly, for various reasons, including maintenance, sortation shuttles may be removed from a shuttle rail track and then later reintroduced. During such reintroduction, a shuttle orientation may be reversed, which may impact downstream processes. For example, a shuttle may be configured to convey items in two directions using a bi-directional conveyance assembly. However, if the shuttle orientation is reversed, the shuttle may convey items or containers in an opposite direction than intended. In addition, if the shuttle has a wireless power receiver or other component that is positioned on a certain side of the shuttle, the component may not be in the correct position when the shuttle is in the wrong orientation, and may therefore not function properly.

(15) To address such instances without having to remove the shuttle from the shuttle rail track and causing additional downtime, embodiments of the disclosure include systems and methods for automated reorientation of sortation shuttles. Embodiments include tracks having dynamic turntable-style rotatable portions that allow for rapid reorientation of sortation shuttles. Some tracks may include more than one rotatable portion, such as rotatable portions positioned at or before an induction portion of the sortation system, at or before a packing system accessible by the shuttle rail system, at or before entering a sortation system, and/or other locations. The automated reorientation systems may include one or more electromagnets configured to rotate with a portion of the track, where the electromagnet(s) can be energized to secure the shuttle in place during rotation. After rotation, the shuttle may continue moving downstream along the track. The rotatable portion of the track may be configured to rotate both in a clockwise direction and counter-clockwise direction, and may alternate rotating in each direction, such that the rotatable portion goes back and forth rotating in a clockwise direction and then a counter-clockwise direction so as to avoid rotating a complete 360 degrees.

(16) Embodiments may therefore automatically reverse shuttle orientation without having to remove shuttles from the shuttle rail system. For instance, certain shuttles may include one or more magnets, such as permanent magnets, underneath the shuttle that interact with electromagnets disposed along a set of rails. The permanent magnet and electromagnets may work together to form a linear induction motor that propels the shuttle. Because the shuttles may be propelled via electromagnetic propulsion, the shuttle may be secured during rotation using a rotatable electromagnet coupled to the rotatable portion of the track.

(17) As a result of the improve functionality provided by the automated shuttle reorientation systems and methods described herein, flexibility of the processing of items at the fulfillment center may be increased, such as by providing the ability to reorient shuttles without any, or with limited, manual intervention. Some embodiments include optimized process flows for processing of orders at fulfillment centers, as well as process flows or methods to increase speed of consolidating products in a multi-item order as a result of improved speed in transportation of items and/or containers. As a result, throughput of fulfillment centers may be improved, and/or logistics of fulfillment center operations may be less complicated.

(18) Referring to FIG. 1, an example use case 100 for automated reorientation of sortation shuttles is depicted in accordance with one or more embodiments of the disclosure. Although discussed in the context of online orders, other embodiments may be directed to any suitable use case where containers or items are transported, such as instances where objects are picked from inventory, placed into containers, containers are transported, and so forth.

(19) In FIG. 1, a fulfillment center may be a traditional fulfillment center and may include an inventory field 110, a routing sorter 160, one or more item sorting machines 170, and one or more packing stations 180. The inventory field 110 may include a storage platform, or a portion of the fulfillment center at which products picked from product inventory are placed. Robots may be used to pick products from inventory and to deliver to the robotic storage platform in some instances, while in other instances, manual labor or a combination thereof may be used to pick products. The picking process at the robotic storage platform may include locating a product in an order, obtaining the product, and sending the product to a robotic storage platform, such as via a conveyor belt. In the illustrated embodiment, products at the robotic storage platform may be placed in a container, such as a tote.

(20) The inventory field 110 may include multiple items that are in inventory. The items may be used to fulfill orders. The inventory field 110 may be a robotic field in some instances. One or more picking stations 130 may be positioned along a perimeter 120 of the inventory field 110. The picking stations 130 may be manually operated or may include robotic components, or a combination thereof. In some instances, picking of items from the inventory field 110 may be completed by robots that include automated robotic arms, where the items are delivered to the picking stations 130 after being retrieved from the inventory field 110. Any number of picking stations 130 may be included, and the picking stations 130 may be located in a different position than that illustrated in FIG. 1.

(21) In a traditional fulfillment center, such as that illustrated in FIG. 1, one or more conveyors 150 may be disposed about the inventory field 110. For example, conveyors 150 may be disposed along the perimeter 120 of the inventory field 110. The conveyors 150 may run adjacent to the picking stations 130 in some embodiments. Any suitable conveyor configuration may be used. In the illustrated example, the conveyors 150 may include belts or rollers that run alongside the picking stations 130 and include one or more paths to one or more routing sorters.

(22) The conveyors 150 may be used to transport one or more containers, such as totes 140. For example, as totes 140 move along the conveyors 150, items may be moved from the picking stations 130 into respective totes 140. The totes 140 may be associated with particular item sorting machines, and may be moved using the conveyors 150 to a routing sorter 160. In contrast, embodiments of the disclosure may not include some or all of the conveyors 150, and instead may include rails that may be used to guide shuttles from one location to another. The rails may be used with automated reorientation systems for shuttles described herein.

(23) The routing sorter 160 may be configured to route, divert, or otherwise guide certain totes to an item sorting machine. The routing sorter 160 may include any combination of ramps, slides, rollers, arms, guides, and/or other components to route totes to a particular item sorting machine. At the routing sorter 160, totes including products that have been picked may be routed to the appropriate or designated item sorting machine. For example, the routing sorter 160 may determine an identifier associated with the tote, and may determine an item sorting machine associated with the tote using the identifier. The routing sorter 160 may route or direct the tote to the appropriate item sorting machine.

(24) A number of item sorting machines 170 may be coupled to the routing sorter 160. For example, a first item sorting machine 172, a second item sorting machine 174, a third item sorting machine 176, and so forth may be coupled to the routing sorter 160. The routing sorter 160 may optionally guide totes to the item sorting machines to which they are assigned. For example, a first tote 162 may include item 1, item 16, and item 23, and may be assigned to the first item sorting machine 172. The routing sorter 160 may therefore route the first tote 162 to the first item sorting machine 172 for sortation of the respective items. A second tote 164 may include item 1656, and may be assigned to the second item sorting machine 174. The routing sorter 160 may therefore route the second tote 164 to the second item sorting machine 174 for sortation of the item. A third tote 166 may include item 989, item 145, and item 34, and may be assigned to the third item sorting machine 176. The routing sorter 160 may therefore route the third tote 166 to the third item sorting machine 176 for sortation of the respective items.

(25) Some or all of the item sorting machines may be associated with one or more packing stations 180 that may be used to pack items into a shipment when a multi-item order is complete. For example, the first item sorting machine 172 may be coupled to a first packing station 182, the second item sorting machine 174 may be coupled to a second packing station 184, the third item sorting machine 176 may be coupled to a third packing station 186, and so forth. The item sorting machines may be configured to receive items from totes that have one or more, or multiple, items. The number of totes and/or the number of items associated with respective item sorting machines may be balanced, and multiple totes may be routed to the first item sorting machine 172 and the second item sorting machine 174 at the same time.

(26) At any of the stages of the example fulfillment process of FIG. 1 where handling of containers is used and/or shuttles are used to transport items or containers between systems, systems as described herein may be used for automated reorientation of sortation shuttles.

(27) Embodiments of the disclosure include systems and methods for automated reorientation of sortation shuttles. Certain embodiments may improve processing speed and/or throughput of fulfillment centers. Certain embodiments may improve performance of mechanical equipment for sortation and/or consolidation of items. While described in the context of online orders, aspects of this disclosure are more broadly applicable to other forms of object handling.

(28) Example embodiments of the disclosure provide a number of technical features or technical effects. For example, in accordance with example embodiments of the disclosure, certain embodiments of the disclosure may improve processing speed, throughput, and/or efficiency of fulfillment centers. The above examples of technical features and/or technical effects of example embodiments of the disclosure are merely illustrative and not exhaustive.

(29) One or more illustrative embodiments of the disclosure have been described above. The above-described embodiments are merely illustrative of the scope of this disclosure and are not intended to be limiting in any way. Accordingly, variations, modifications, and equivalents of the embodiments disclosed herein are also within the scope of this disclosure. The above-described embodiments and additional and/or alternative embodiments of the disclosure will be described in detail hereinafter through reference to the accompanying drawings.

ILLUSTRATIVE EMBODIMENTS AND USE CASES

(30) FIG. 2 is a schematic illustration of an example use case 200 and facility layout for automated reorientation of sortation shuttles in accordance with one or more embodiments of the disclosure. Other embodiments may include additional or fewer components. The illustration of FIG. 2 may not be to scale, and may not be illustrated to scale with respect to other figures.

(31) In FIG. 2, a fulfillment center may include an inventory field 210, at which products or other items may be stored in inventory. As the items are ordered in online orders, the products may be picked from the inventory field 210 and routed for downstream processing in the fulfillment center. The items may be picked manually, using robots, vehicles, or a combination thereof.

(32) The picked products may be placed into one or more containers and the containers may be transported using one or more shuttles, such as one or more shuttles on rails 220. The shuttles on rails 220 may include container shuttles that are configured to transport items and/or containers from one location to another via rails. The rails may include switching rail components that allow for the shuttles to move from one set of rails to another. The shuttles on rails 220 may transport containers from the inventory field 210 to one or more downstream processes, such as a sortation system 230, or a packing system 240. For example, the sortation system 230 may be a system at which items picked from the inventory field 210 may be re-sorted into respective totes or other containers for particular orders. For example, items for different orders may be placed into containers that are transported by the shuttles on rails 220 from the inventory field 210. The containers may be sent to the sortation system 230 for sorting into particular orders. The packing system 240 may be a station at which one or more items associated with an order may be packed into a box or other container for shipment. A shipping label may be applied and the package may be dispatched to a loading dock or elsewhere for shipment. Other destinations or downstream processes in addition to, or instead of, the sortation systems and packing systems may be used.

(33) A rail system 260 is depicted in schematic view in FIG. 2. The rail system 260 is an example of a network of rails that may be used by shuttles to transport containers from one location to another. The network of rails may include locations at which a shuttle can be directed to a straight path or to a loop, turn, oval, circle, and/or other geometries that involve a change in direction of a shuttle on the rails. Such changes in direction may be implemented using switching rail components. Shuttles can be routed to a maintenance area 290 connected to the rail system 260 using the systems described herein. The rail system 260 may include rails that link various systems, such as sortation systems, to each other and/or to other systems, such as container handling systems, manual induction systems 290, and so forth. For example, the rail system 260 may link a first sortation system 270 to a second sortation system 272, as well as to a first container handling system 280, a second container handling system 282, a third container handling system 284, and so forth. The rail system 260 may be used to connect any of the systems to each other and/or other systems.

(34) Shuttles may move along the rails of the rail system 260. The shuttles may include linear drive motors or other drive components. Some drive components may provide a drive force via electromagnetism. As a result, one or more electromagnets may be disposed along the network of rails. Shuttles may optionally include a conveyor belt that may have a first set of one or more raised flaps and a second set of one or more raised flaps. The first set of raised flaps may form a first barrier along a first open-ended side of the shuttle, and the second set of raised flaps may form a second barrier along a second open-ended side of the shuttle to prevent items rolling off of the conveyor belt. The shuttles may include an on-board drive motor configured to move the conveyor belt in a forward direction and/or a reverse direction. The shuttles may include a magnet disposed on a lower surface of the shuttle. The magnet may be used to propel and/or secure the shuttle. For example, the magnet may prevent the shuttle from moving while the vehicle is in motion and the linear drive motor is engaged. To onboard or offload containers, the linear drive motor of the shuttle or other component may be used in conjunction with the magnet to impart motion. The automated shuttle reorientation systems described herein may be positioned at one or more locations along the rail system 260.

(35) FIG. 3 is a schematic illustration of a perspective view of a shuttle rail system 300 in accordance with one or more embodiments of the disclosure. Other embodiments may include additional or fewer components. The illustration of FIG. 3 is not to scale, and may not be illustrated to scale with respect to other figures. The system illustrated in FIG. 3 may be used with the automated reorientation systems for shuttles discussed with respect to FIGS. 1-2, and/or may be used with any of the systems described herein.

(36) The shuttle rail system 300 may be configured to provide continuous rail for switching the direction of a shuttle 350 in an electromagnetically propelled shuttle-on-rail arrangement. Shuttle-on-rail arrangements may be used in many systems, such as sortation systems, pick systems, delivery systems, etc. The shuttle rail system 300 may include rail switch mechanisms to allow the rail to be directed to alternate path. Shuttle-rail arrangements that are based on electromagnetic propulsion, such as linear drive motors, may have sets of electromagnets arranged along the direction of the rails. Shuttles may also have a magnet, such as a permanent magnet, coupled to a lower side of the shuttle. The electromagnet and the permanent magnet may have to be separated by a very narrow gap for optimal performance. Such factors may make removal of the shuttle 350 from the shuttle rail system 300 difficult, due to potential unintended interaction between the magnets. Embodiments of the disclosure include systems that allow for reorientation of shuttles without having to fully remove shuttles from the rails.

(37) The shuttle rail system 300 may include a first branched path 310, where if shuttles were moving along the shuttle rail system 300 in a clockwise direction, the shuttle could move in either a straight direction along the oval path of the shuttle rail system 300, or may make a left-handed curve onto a separate path of the shuttle rail system 300. Similarly, a second branched path 320 may allow for merging of shuttles that took a left curve at the first branched path 310 to merge back onto the oval path of the shuttle rail system 300. Any number of curved path and straight path intersections may be included in the shuttle rail system 300. For example, the shuttle rail system 300 may include a third branched path 330 and a fourth branched path 340. The shuttle rail system 300 may form a closed loop track in some embodiments.

(38) A maintenance area may be connected to the shuttle rail system 300 and may be accessible via the shuttle rail system 300. For example, the shuttle 350 moving along the shuttle rail system 300 may direct itself autonomously to the maintenance area by following a branched path, such as that illustrated in FIGS. 7A-7B (e.g., where the shuttle 350 is depicted in FIG. 3), where the branched path may provide ingress and egress to a main path of the shuttle rail system 300.

(39) FIG. 4 is a schematic illustration of various views of portions of a shuttle rail system 400 in accordance with one or more example embodiments of the disclosure. Other embodiments may include additional or fewer components. The illustration of FIG. 4 is not to scale, and may not be illustrated to scale with respect to other figures. The system illustrated in FIG. 4 may include the same shuttle and shuttle rail system discussed with respect to FIGS. 1-3.

(40) FIG. 4 depicts a portion of the shuttle rail system 400 in a top schematic view. The shuttle rail system 400 may include one or more sets of rails 410 on which shuttles 420 may ride. The rails 410 may guide shuttles 420 to various locations. Each set of rails 410 may include two rails, so as to support two sides of a shuttle 420 on the rails. The shuttle rail system 400 may include a number of supports disposed between the two rails of a set of rails 410. A number of electromagnets 470 may optionally be disposed along the rails at various intervals. The electromagnets 470 may be configured to propel shuttles along the respective sets of rails.

(41) The shuttle rail system may include a shuttle calibration/maintenance zone 430 that is connected to the shuttle rail system 400 and is accessible via the tracks. For example, a shuttle may seamlessly move from the set of rails 410 to the shuttle calibration/maintenance zone 430. The shuttle calibration/maintenance zone 430 may be a section of shuttle track that leads to a maintenance area at which one or more robotic manipulators are disposed. The shuttle calibration/maintenance zone 430 may be accessible as a branched path, a loop, and/or a straight track that can be used for shuttles to move back-and-forth along.

(42) A perspective view 440 in FIG. 4 depicts the shuttle 420 engaged with the shuttle rail system 400. The shuttle 420 may include wheels 450 that engage the rails 410. Some embodiments may include four wheels 450, while other embodiments may include different numbers of wheels. Any suitable number and size of wheels may be used to engage with the rails 410.

(43) The shuttle 420 may include a permanent magnet 460 disposed underneath the shuttle 420. The permanent magnet 460 may interact with the electromagnets 470 to electromagnetically propel the shuttle 420. The electromagnets 460 may therefore be a linear synchronous motor in some embodiments.

(44) Although the shuttle 420 is depicted as traveling in a sideways configuration with respect to the shuttle rail system 400 (e.g., a payload on the shuttle 420 may be moving sideways with respect to the shuttle rail system 400, etc.), in other embodiments, the shuttle 420 may be oriented differently.

(45) The shuttle rail system 400 may therefore include the set of rails 410 that form a track having a central axis. The set of rails 410 may include a first rail segment on a first side of the central axis and a second rail segment on a second side of the central axis. The shuttle rail system 400 may include the set of electromagnets 470 disposed along the central axis of the track. The shuttle rail system 400 may be used with the shuttles 420, where the shuttles 420 are configured to transport one or more items or containers from a first location to a second location using the set of rails 410. The shuttle may include a first pair of wheels 450 disposed at a front end of the shuttle 420, and a second pair of wheels 450 disposed at a rear end of the shuttle 420. In some embodiments, the shuttle 420 may include a conveyor assembly having a central axis that is transverse to the central axis of the track, such as in the embodiment depicted in FIG. 4. The shuttle 420 may include the permanent magnet 460 coupled to a lower surface of the shuttle 420. The permanent magnet 460 may be configured to engage with the set of electromagnets 470 to propel the shuttle 420.

(46) FIGS. 5A-5B are schematic illustrations of a shuttle rail system 500 with an automated shuttle reorientation system in accordance with one or more embodiments of the disclosure. Other embodiments may include additional or fewer components. The illustrations of FIGS. 5A-5B are not to scale, and may not be illustrated to scale with respect to other figures. The automated shuttle reorientation system illustrated in FIGS. 5A-5B may be the same automated shuttle reorientation system discussed with respect to FIGS. 1-4.

(47) In FIG. 5A, the shuttle rail system 500 may have an automated shuttle reorientation system. The shuttle rail system 500 may include a track formed of one or rail segments 540. One or more electromagnets 520 may be disposed along the track. One or more supports 560 may be disposed between parallel rail segments 540 to provide structural support for the shuttle rail system 500.

(48) The automated shuttle reorientation system may include a rotatable portion 510 depicted in static view and in a dynamic view 502 in FIG. 5A. The rotatable portion 510 may be a portion of the track or may be coupled to the track. The rotatable portion 510 may be configured to rotate at least 180 degrees, and in some embodiments, less than 360 degrees. In other embodiments, the rotatable portion 510 may be configured to rotate 360 degrees. The rotatable portion 510 may be configured to rotate in one or more of a clockwise direction, a counter-clockwise direction, or both directions. The rotatable portion 510 may rotate about a vertical axis 512. In some embodiments, the rotatable portion 510 may alternate a direction of rotation, such as first rotating in a clockwise direction, and then rotating in a counter-clockwise direction, then in a clockwise direction, and so forth.

(49) As the rotatable portion 510 rotates, the rotatable portion 510 may include one or more electromagnets 520 that rotate with the rotatable portion 510. The rotatable portion 510 may include one or more supports 560 that rotate with the rotatable portion 510. The rotatable portion 510 may include a first rail segment 530 and a second rail segment 532 that rotate with the rotatable portion 510. The electromagnet 520 may be used to secure a shuttle in position during rotation. For example, the electromagnet 520 may be energized and engage a permanent magnet on a shuttle to prevent the shuttle from moving during rotation. The rotatable portion 510 may include a rotation actuation device 550 configured to cause rotation of the rotatable portion 510, as discussed in more detail with respect to FIGS. 6A-6B.

(50) As depicted in FIG. 5B, the rotatable portion 510 may be configured to rotate a shuttle 580 so as to reverse an orientation of the shuttle. The shuttle rail system 500 may include a first portion (e.g., formed by rail segments 540 at the right side of the page in FIG. 5A, etc.), a second portion (e.g., formed by rail segments 540 at the left side of the page in FIG. 5A, etc.), and the rotatable portion 510. The rotatable portion 510 may include a first end and a second end, where the rotatable portion 510 may be configured to rotate from a first position 570 to a second position 574, and where the first end is adjacent to the first portion of the track in the first position 570, and the first end is adjacent to the second portion of the track in the second position 574. The shuttle rail system 500 may include a shuttle 580 configured to move along the track, where the rotatable portion 510 of the track is configured to rotate the shuttle 580 from a first orientation to a second orientation. The second reorientation may be opposite or a reverse of the first orientation.

(51) In FIG. 5B, the shuttle rail system 500 is depicted with the shuttle 580. The rotatable portion 510 may be configured to rotate the shuttle 580 such that an orientation of the shuttle is modified. In some instances, the orientation of the shuttle 580 may be reversed by the rotatable portion 510. The rotatable portion 510 may be in a first position 570, where a first end of the rotatable portion 510 is adjacent to a first portion of the track. The shuttle 580 may move onto the rotatable portion 510. Once secured on the rotatable portion 510, the rotatable portion 510 may rotate as shown in intermediate view 572 and wherein the electromagnet(s) of the rotatable portion 510 are energized 582 to secure the shuttle 580. The rotatable portion 510 may rotate to the second position 574, where the first end of the rotatable portion 510 is adjacent to a second portion of the track. Once in the second position 574, the electromagnet may be de-energized or energized 584 in a different configuration to propel the shuttle 580 along the track. For example, the shuttle 580 may include one or more permanent magnets, and the rotatable portion 510 may include an electromagnet configured to rotate from the first position to the second portion, where the shuttle 580 can be propelled via interaction between the electromagnet and the permanent magnet.

(52) The track may include a first support, such as the supports 560, having a fixed position at the first portion, and a second support, such as supports 560, configured to rotate with the rotatable portion 510. The rotatable portion may be configured to rotate less than 360 degrees in some embodiments, and at least 360 degrees in other embodiments. Because the track may be a closed loop track, the automated reorientation system may allow for reorientation of shuttles without having to remove the shuttle from the track. The electromagnet 520 may secure the shuttle 580 in position during rotation of the rotatable portion 510. Reversal of shuttle orientation may be represented by conveyance axis, for example, where the shuttle 580 has a conveyor having a first central axis that is transverse to a second central axis of the track.

(53) FIGS. 6A-6B are schematic illustrations of an automated shuttle reorientation system 600 in accordance with one or more embodiments of the disclosure. Other embodiments may include additional or fewer components. The illustrations of FIGS. 6A-6B are not to scale, and may not be illustrated to scale with respect to other figures. The automated shuttle reorientation area illustrated in FIGS. 6A-6B may be the same systems discussed with respect to FIGS. 1-5B.

(54) In FIG. 6A, the automated shuttle reorientation system 600 is depicted in top view and cross-sectional view. In the top view, the automated shuttle reorientation system 600 includes a rotatable portion 610. The rotatable portion 610 may include rail segments having angled ends 612 that interface with corresponding angled ends along the adjacent portions of the track, so as to allow the rotatable portion 610 to rotate without leaving gaps between the rotatable portion 610 and the adjacent portions of the track.

(55) As depicted in cross-sectional view along A-A in FIG. 6A, the automated shuttle reorientation system 600 may include one or more electromagnets or linear motors 620. The automated shuttle reorientation system 600 may include a servo gear motor 630 or other mechanism to drive rotation of the rotatable portion 610, such as one or more of a rotating solenoid, a belt-driven system, a rotary actuator, or another suitable device. The automated shuttle reorientation system 600 may include a belt drive 640 configured to impart motion to the rotatable portion 610, and one or more belts 650 or gears coupling the rotatable rail segments to the actuator (e.g., the servo gear motor 630, etc.). As depicted in close-up bottom perspective view, the servo gear motor 630 may be coupled to a belt-driven system to impart motion. For example, a belt may be used to drive rotational motion due to space constraints. One or more apertures 660 in gears or slew bearings and belt pulleys may be used to route cables for the rotating linear motor or electromagnet to avoid tangle.

(56) In FIG. 6B, the automated shuttle reorientation system 600 is depicted with a close-up view of an interface between adjacent angled edges 612. The rotatable portion 610 may include a rotatable rail segment with an angle edge that is aligned with a corresponding angled edge of an adjacent fixed rail segment. The rotatable portion 610 may include a member 670 configured to slide along a groove 672 formed in the fixed rail segment to guide movement of the rotatable portion 610. In some embodiments, the member 670 may be configured to engage the groove 672 when the rotatable portion is in the first position. One or more guide wheels 680 may be included to guide movement into, through, and out of the groove 672.

(57) The automated shuttle reorientation system 600 may therefore be disposed between a first portion of the track and a second portion of the track. The first portion may have a first rail segment having a first angled edge, and the second portion may have a second rail segment having a second angled edge. The rotatable portion may have a third rail segment having a third angled edge configured to interface with the first angled edge when the rotatable portion is in the first position, and with the second angled edge when the rotatable portion is in the second position. The first rail segment or the first portion of the track may have the groove 672.

(58) FIGS. 7A-7B are schematic illustrations of an automated shuttle reorientation system 700 in accordance with one or more embodiments of the disclosure. Other embodiments may include additional or fewer components. The illustrations of FIGS. 7A-7B are not to scale, and may not be illustrated to scale with respect to other figures. The automated shuttle reorientation system illustrated in FIGS. 7A-7B may be different from the systems discussed with respect to FIGS. 1-6B.

(59) In FIG. 7A, an alternate shuttle reorientation system is depicted. The automated shuttle reorientation system 700 may use electromagnets or linear motors to guide shuttle movement and manage shuttle orientation when entering and exiting a track 710. The track 710 may include a linear path and a branched path, as depicted in FIG. 7A. The automated shuttle reorientation system 700 may include linear motors 740 to propel a shuttle 750 along the track.

(60) The automated shuttle reorientation system 700 may include a first set of electromagnets 710 disposed along a side of the linear path, a second set of electromagnets 730 disposed along a first side of the branched path, and a third set of electromagnets 720 disposed along a second side of the branched path. The shuttle 750 may have one or more permanent magnets configured to interact with the first set of electromagnets 710, the second set of electromagnets 730, and the third set of electromagnets 720. For example, the shuttle 750 may have a first permanent magnet disposed along a lower surface to interact with the linear motors 740, a second permanent magnet disposed along a left-hand side surface to interact with the first set of electromagnets 710 and the third set of electromagnets 720, and a third permanent magnet disposed along a right-hand side surface to interact with the second set of electromagnets 730. In this manner, shuttle orientation can be managed by selective energizing of the different sets of electromagnets.

(61) For example, in FIG. 7A, for the shuttle 750 to continue moving along the linear path, the first set of electromagnets 710 may be energized (while the second set of electromagnets 730 and the third set of electromagnets 720 are not energized) while the linear motors 740 propel the shuttle 750, such that the shuttle 750 bypasses the branched path and continues along the linear path.

(62) In FIG. 7B, at a first instance 770, for the shuttle 750 to exit the linear path and enter the branched path, the second set of electromagnets 730 may be energized (while the first set of electromagnets 710 and the third set of electromagnets 720 are not energized) while the linear motors 740 propel the shuttle 750, such that the shuttle 750 is pulled onto the branched path and continues along the branched path. At a second instance 772, the shuttle 772 continues along the branched path. At a third instance 774 and fourth instance 776, for the shuttle 750 to return to the linear path from the branched path, the third set of electromagnets 720 may be energized (while the first set of electromagnets 710 and the second set of electromagnets 730 are not energized) while the linear motors 740 propel the shuttle 750, such that the shuttle 750 is pulled onto the linear path and continues along the linear path. In this manner, the shuttle orientation is maintained in a correct position when exiting and re-entering the linear path, instead of potentially reversing. Moreover, shuttle orientation may be reversed by selective activation of the different sets of electromagnets. Accordingly, in some embodiments, the shuttle 750 leaves the linear path and reenters the linear path having a reversed orientation.

(63) Some embodiments may include a controller configured to cause the first set of electromagnets 710 to be energized to guide the shuttle 750 along the linear path, cause the second set of electromagnets 730 to be energized to guide the shuttle 750 from the linear path to the branched path, and cause the third set of electromagnets 720 to be energized to guide the shuttle 750 from the branched path to the linear path. The shuttle 750 may include one or more permanent magnets, such as a first permanent magnet disposed under the shuttle. The shuttle 750 may include a second permanent magnet on a first side of the shuttle, and a third permanent magnet on a second side of the shuttle. In other embodiments, instead of permanent magnets on one or more sides of the shuttle 750, the shuttle 750 may include one or more ferrous blocks, such as metal blocks, disposed on one or more sides of the shuttle 750. For example, a first ferrous block may be disposed on a first side of the shuttle 750, and a second ferrous block may be disposed on a second side of the shuttle 750. Any number of ferrous blocks may be included.
