Description

TURNTABLE SYSTEM ML / i ζυου Background of the Invention The supply of products to warehouses from distribution centers has many stages that are subject to errors and inefficiencies. For example, the products might be cases of beverage containers (e.g., cartons of cans and beverage crates containing bottles or cans, etc.). There are many different combinations of flavors, sizes, and types of beverage containers supplied to each warehouse. When palletizing, missing or incorrectly selected product can represent significant additional operating costs. In some implementations, a stretch wrap is placed around a loaded pallet to keep the stacked items stable. The loaded pallet can be placed on a turntable and rotated while the stretch wrap is wound around the items on the pallet. This is time-consuming and occupies valuable warehouse space. Brief Description of the Invention This application provides several types of turntable systems that can be used to validate loaded pallets, wrap loaded pallets with Ref. 330762 an extendable enclosure, or both. In some embodiments, a first ramp rises to the turntable and a second ramp descends from the turntable on the opposite side. In other embodiments, at least two turntables are positioned side by side, optionally with a bridge surface connecting them so that a pallet hoist can be driven from one turntable to the other to place one pallet onto one turntable and the other pallet onto the other turntable according to a method described herein. A validation system without a turntable includes a plurality of cameras around a periphery of a platform weight sensor. In some embodiments, a turntable system includes a first turntable capable of supporting a loaded pallet and a second turntable capable of supporting a loaded pallet. The second turntable is adjacent to the first turntable. A support surface is located between the first and second turntables. This support surface is substantially level with the top surface of the first turntable and the top surface of the second turntable. A first camera can be pointed at the first turntable, and a second camera can be pointed at the second turntable. An extendable wrapping dispenser can be mounted adjacent to the first turntable. A ramp can be installed to provide access to the first turntable. The system may also include a raised cross-bridge. The raised cross-bridge may extend between the first and second turntables. At least one light may be mounted on the raised cross-bridge. A first extendable wrap dispenser may be positioned adjacent to the first turntable, and a first camera may be directed toward the first turntable, such that the first turntable is between the first extendable wrap dispenser and the first camera. The elevated cross-bridge may include a horizontal portion extending between the first and second turntables and a vertical support that supports the horizontal portion. The first camera can be mounted on the vertical support. A second extendable wrap dispenser can be adjacent to the second turntable and a second camera can be directed towards the second turntable, such that the second turntable is between the second extendable wrap dispenser and the second camera. According to another embodiment, a validation system includes a platform weight sensor. A plurality of cameras are mounted around the periphery of the platform weight sensor and are directed toward an area above it. At least one computer receives images from the plurality of cameras and weight information from the platform weight sensor. The computer can be programmed to analyze images and identify multiple SKUs associated with multiple items stacked in the images. The computer can include a machine learning model trained on images of beverage container packages. The validation system may also include an enclosure surrounding the platform's weight sensor, with a plurality of cameras mounted within the enclosure. The plurality of cameras may include four cameras, one to capture each side of the loaded pallet. The corral may include a gate that swings between an open and a closed position, and one of the cameras may be mounted on the gate. According to various modalities, a turntable system includes a turntable that includes a weight sensor, a first ramp that goes up to the turntable, and a second ramp that goes down from the turntable. ML / E / ZuZz / uZuOy The turntable system may include at least one camera positioned adjacent to the turntable. The turntable system may include an extendable wrapper dispenser mounted adjacent to the turntable. The turntable may include a hard stop that prevents damage to the weight sensor caused by driving over the turntable with a pallet jack. One method for handling loaded pallets includes carrying a first loaded pallet and a second loaded pallet onto a first turntable, and then placing the second loaded pallet onto a second turntable. The first loaded pallet is then placed on the first turntable. The second loaded pallet is rotated onto the second turntable, and the first loaded pallet is rotated onto the first turntable. The method may include subsequently lifting the second loaded pallet and then lifting the first loaded pallet. The method may also include subsequently carrying the first loaded pallet and the second loaded pallet onto the second turntable. In this method, the first loaded pallet and the second loaded pallet can be carried on the forks, such as the forks of a pallet jack (forklift with ML / E / ZuZZ / u ZUOU platform for driver, pallet skid, pallet truck, etc.) and the first loaded pallet and the second loaded pallet can be lifted with the tips. The method may include placing a wrap around the second pallet loaded during rotation. The method may include an image of the second pallet loaded during the rotation.

Detailed Description of the Invention Figure 1 is a high-level view of a supply system 10 comprising one or more distribution centers 12, a central server 14 (e.g., a cloud computer), and a plurality of warehouses 16. A plurality of trucks 18 or other delivery vehicles each transport goods 20 on pallets 22 from one of the distribution centers 12 to a plurality of warehouses 16. Each truck 18 carries a plurality of pallets 22, which may be half pallets, each loaded with a plurality of goods 20 for delivery to one of the warehouses 16. A wheeled skid 24 is provided on each truck 18 to facilitate the delivery of one or more pallets 22 of goods 20 to each warehouse 16. In general, the goods 20 may be loaded onto half pallets 22, full-size pallets, handcarts, or trolleys—all of which considered platforms in this document. Each distribution center 12 includes one or more collection stations 30 and one or more validation stations ML / i ζυου 32. Each distribution center 12 includes one or more loading stations 34, such as a loading stand for loading trucks 18. Each distribution center 12 can have a plurality of loading stations 34. Each distribution center 12 includes a DC computer 26. The DC computer 26 receives orders 60 from the warehouses 16 and communicates with the central server 14. Each DC computer 26 receives orders and generates picking slips 64, each of which contains a list and quantity of the SKUs. Alternatively, orders 60 can be sent from the DC computer 26 to the central server 14 to generate the picking slips 64, which are then synchronized back with the DC computer 26. Some or all of the distribution centers 12 may include a training station 28 to generate image information and other new product information 20 that can be transmitted to the central server 14 for analysis and future use. The central server 14 can include a plurality of distribution center accounts 40, including DC1 - DCn, each associated with a distribution center 12. Each DC account 40 includes a plurality of warehouse accounts 42, including warehouse 1 - warehouse n. Purchase orders 60 and picking slips 64 for each warehouse are stored in account 42. ML / i zou of the associated warehouse. The central server 14 also includes one or more machine learning models trained on a plurality of SKU files 44, including SKU 1 SKUn. The models are periodically synchronized with the DC 26 computers. Each SKU 44 file contains information for a single SKU. An SKU can be a single variation of a product that is available at distribution center 12 and can be supplied to one of warehouse 16. Each product at distribution center 12 is associated with a SKU. For example, each SKU might be associated with a particular number of containers (e.g., 12-pack) in a particular shape (e.g., can vs. bottle) of a particular size (e.g., 566.99 g (24 oz)), with particular packaging (cardboard vs. reusable plastic box, etc.), and containing a particular beverage. This information is contained in each SKU 44 file, along with the product name, a product description, product dimensions, and product image information. Each SKU 44 file may also include the product weight.In general, all SKU 44 files that include their associated image information can be generated using training module 28. Machine learning models are trained based on the image information for the SKUs. ML / E / ZuZz / uZuOy Referring also to the flowchart in Figure 2, an order 60 can be received from warehouse 16 at stage 150. As an example, a warehouse employee can place an order 60 using an application or mobile device 52. The order 60 is sent to the distribution center computer 26 (or alternatively to server 14, and then forwarded to the appropriate distribution center computer 26 (e.g., the nearest one)). The distribution center computer 26 analyzes the order 60 and creates a picking slip 64 associated with this order 60 at stage 152. The picking slip 64 assigns each of the SKUs (including the quantity of each SKU) in the order. The picking slip 64 specifies how many pallets 22 will be required for this order (as determined by the DC 2 computer 6).The DC 26 computer can also determine which SKUs should be loaded close to each other on the same pallet 22, or if more than one pallet 22 is required, which SKUs should be loaded on the same pallet 22. Figure 3 shows a portion of an exemplary picking station 30 from Figure 1. Referring to Figures 1 and 3, workers in the distribution center read the pallet identification (e.g., by means of RFID, barcode, etc.) on pallet(s) 22 on a pallet truck 24a, such as with a mobile device or a reader mounted on the pallet truck 24a. The racks may contain a ML / E / ZuZZ / uZUOy variety of items 20 for each SKU, such as the first product 20a of a first SKU and a second product 20b of a second SKU (collectively, products 20). In practice, there will be products associated with hundreds or thousands of different SKUs. A worker reading a computer or mobile device screen displaying picking slip 64 retrieves each product 20 and places it onto one of the pallets 22, following instructions via the computer or mobile device screen. Alternatively, pallet 22 can be loaded by automated handling equipment. Workers place the items 20 onto the pallets 22 according to the picking slips 64, and the pallet IDs are reported to the DC 26 computer at step 154. After loading the two pallets 22, the next pallet 22 (or two pallets 22) is taken to picking station 30 until all the SKUs required by picking sheet 64 are loaded onto as many pallets 22 as required by that picking sheet 64. Then, the pallets 22 are loaded for the next picking sheet 64. The DC 26 computer records the pallet IDs of the pallet 22 that have been loaded with the particular SKUs for each picking sheet 64. Picking sheet 64 can associate each pallet ID with each SKU. ML / i ζυου After being loaded, each loaded pallet 22 is validated at validation station 32, which may be adjacent to, or part of, picking station 30. As will be described in more detail later, at least one still image, and preferably four still images, of the products 20 on pallet 22 is taken at validation station 32 in step 156 of Figure 2. Preferably, a still image is taken of each of the four sides of the loaded pallet 22. The pallet ID of pallet 22 is also read. The images are analyzed (e.g., with machine learning models) to determine the SKUs of the products 20 currently on the identified pallet 22 in step 158.The SKUs of the 20 products on pallet 22 are compared with the picking sheet 64 by means of the DC 26 computer at stage 160 to ensure that all SKUs associated with the pallet ID of pallet 22 on the picking sheet 64 are present on the correct pallet 22, and that no additional SKUs are present. Figures 4 to 11 show an exemplary validation station that could be used in the system of Figure 1. With reference to Figure 4, the validation station may include a turntable 67 with at least one camera 68 and an RFID reader 70 (and / or barcode reader) mounted adjacent to it. The lights 65 The ramps are directed towards the turntable 67. A first ramp 76 can lead from the floor to the turntable 67 and a second ramp 77 can lead from the turntable 67 to the floor. A weight sensor can be incorporated into the turntable 67. As shown in Figure 5, the operator can place a loaded pallet 22 on the turntable 67 and another on or near the turntable 67, such as on the ramp 76. Referring to Figure 6, the operator uses a tablet (or other UI device) to initiate the validation. The camera 68 takes at least one image of the loaded pallet 22 while the turntable 67 is rotating the loaded pallet 22. Alternatively, the camera 68 can rotate around the loaded pallet 22. Again, preferably four still images are taken, one of each side of the loaded pallet 22. The RFID reader 70 (or barcode reader, or similar) reads the pallet ID (a unique serial number) of pallet 22. The validation station 32 includes a local computer 74 communicating with the camera 68, the RFID reader 70, and the weight sensor. Computer 74 controls the turntable 67 and the lights 65. Computer 74 can communicate with the DC computer 26 (and / or the server 14) via a wireless network card. The image(s) and pallet ID ZUOU are sent to server 14 via the network and are associated with picking list 64 (Figure 1). The total weight of the expected products 20 (according to picking list 64) and pallet 22 can be compared with the weight measured on the turntable 67 for confirmation. Referring to Figure 7, if the loaded pallet 22 is successfully validated, the tablet indicates this. The operator picks up pallet 22, and the tablet directs it to the correct support door. Referring to Figure 8, if the validation station detects an error in loaded pallet 22, an alert is generated, such as via the tablet. The operator is then instructed (also via the tablet) to take pallet 22 to QC station 33 for a QC check. In Figure 9, the operator places pallet 22 at QC station 33 for physical inspection. A tablet at QC station 33 displays the necessary information to the audit operator, such as which SKUs are missing and / or which SKUs are present on pallet 22 but should not be. In Figure 10, after validation or correction at QC station 33, pallet 22 can be wrapped using an automatic wrapping machine 66. Alternatively, as shown in Figure 11, pallet 22 can be wrapped ML / i ζυου manually. Figures 12 to 24 show another embodiment of a validation station. In Figures 12 and 13, the validation station includes a pen 69 with a gate 71 surrounding a weight sensor 104 on the platform (for example, a platform supported by load cells). Four cameras 68 are mounted on the pen 69, one on each of the three sides of the pen 69 and one above the gate 71. The gate 71 can be configured to open upon sufficient weight being applied to a platform 110 just outside the gate 71. Again, the computer 74 receives images from the cameras 68 and the weight from the weight sensor 104 on the platform. The computer 74 is also programmed to control the gate 71 as described in this document. Referring to figure 14, when the operator goes up to platform 110 adjacent to corral 69 with the loaded pallet 22 on the elevator, gate 71 opens automatically, as shown in figure 15. Computer 74 receives a signal from platform 110 indicating the weight on platform 110 and generates a signal that causes gate 71 to open. Referring to figure 16, the operator places platform 22 on weight sensor 104 of the platform inside pen 69 and exits pen 69. Gate 71 closes (figure 17). In Figure 18, the four cameras 68 each take ZUOU captures an image of one side of the loaded pallet 22, which could occur simultaneously or rapidly in sequence. The weight sensor 104 measures the weight of the loaded pallet 22. The computer 74 receives the four images and the weight measurement. The images are evaluated using machine learning models (for example) to identify the SKUs associated with each item on pallet 22, as described above. The identified SKUs are compared with the expected SKUs from the picking list. Referring to figures 19 and 20, if the loaded pallet 22 is validated, then gate 71 opens automatically, and a tablet indicates the validation and the tablet indicates the support door to which the operator should take the loaded pallet 22. Referring to Figures 21 and 22, if validation fails, gate 71 automatically reopens. The tablet indicates the failure and instructs the operator to take pallet 22 to QC station 33. After validating pallet 22 (or correcting it at QC station 33), pallet 22 can be wrapped with an automatic wrapper 66 (figure 23) or manually (figure 24). Figure 25 shows a tandem turntable system 210 that includes a first and a second wrapping / validation station 232 that could be used IVIA / t / ZUZZ / UI ZUOU in system 10 of figure 1. Each station 232 can carry out the wrapping and / or verification of a pallet 22 loaded with items 20. Each station 232 includes a rotating platform 267 on which the loaded pallet 22 can be placed for wrapping and / or verification. Each station 232 further includes an associated tower structure 216 adjacent to the turntable 267. Again, the tower structure 216 can provide a wrapping function, dispensing an extendable wrap 218 around the products on the pallet half 22 as the pallet half 22 is rotated by means of the turntable 267. Alternatively, the tower structure 216 can provide a validation function by means of at least one camera 268, which forms an image of the loaded pallet half (and the items on it) as it is rotated by means of the turntable 267. Optionally, each tower structure 216 provides both functions. A REID reader 270 can be mounted near (or on) the tower structure 216 to read a REID tag on the pallet half 22 on the associated turntable 267.Each tower structure 216 has an associated computer that receives images from at least one camera 268 and receives signals from the REID reader 270. The computer also controls the turntable 267. In Figure 25, there is a ramp 230 leading to the first turntable 267 and a bridge 280 between the first turntable 267 and the second turntable 267. The bridge 280 provides a substantially level support surface with the upper surfaces of the first turntable 267 and the second turntable 267. Each turntable 267 may also include a weight sensor 215 that weighs the loaded pallet 22 on the turntable 267 for validation. Referring to Figure 26, a platform forklift 224 carries two pallet halves 22 (shown empty, but they could be loaded) on its ends 284, one pallet half 22 in front of the other. Alternatively, a pallet jack, pallet skid, or pallet truck could be used. Referring to Figures 25 and 26, the user can drive the operator platform forklift 224 up the ramp 230, through the first turntable 267, across (or over) the bridge 280, and place the outer loaded pallet half 22 onto the second turntable 267. The user can then reverse the operator platform forklift 224 until it is in a position to place the inner loaded pallet half 22 onto the first turntable 267. The operator platform forklift 224 then reverses further down the ramp 230 out of the way. Both wrapping / validation stations 232 can be started after the inner pallet half 22 has been placed onto the first turntable 267.Alternatively, the second wrapping / validation station 232 can be started as soon as the rider platform forklift 224 reverses away from the second turntable 267, and the first wrapping / validation station 232 can be started subsequently, as soon as the rider platform forklift 224 reverses away from the first turntable 267. This alternative may be advantageous if the externally loaded pallet 22 on the second turntable 267 is larger and takes longer to wrap and / or may take longer to validate. The stations 232 can be started automatically by the computer associated with each station 232 upon detecting that the rider platform forklift 224 has moved from its associated turntable 267, for example, via the camera 268.Alternatively, the computer could detect the location of the loaded pallet 22 by means of the weight sensor 215 and then wait a predetermined period of time or wait until the camera detects that the rider platform forklift 224 has moved away before initiating the wrapping and / or validation sequence. ML / E / Zuzy / Zuou Alternatively, the user can initiate validation and / or wrapping by means of a signal from a tablet on the driver platform forklift 224 or by means of the buttons on the stations 232. When both loaded pallets 22 are wrapped and / or complete validation, the turntables 267 ensure that the pallets 22 are oriented perpendicular to the ramp 230. For example, the integrated (or adjacent) computer in each tower 216 can use the camera 268 to verify the orientation of pallet 22 and to activate the turntable 267 so that the pallet 22 is perpendicular to the ramp for easy pickup by the rider platform forklift 224. Alternatively, the integrated computer in each tower 216 can ensure that the associated turntable 267 returns to its initial rotation position. The rider platform forklift 224 is driven up the ramp 230 to lift the inner loaded pallet 22, then through the first turntable 267, and then over (or through) the bridge 280 to lift the outer loaded pallet 22.Next, the driver platform forklift 224 reverses from bridge 280, through the first turntable 267, then down ramp 230 and moves the wrapped / validated, loaded pallet halves 22 to the next station. ΜΛ / Ε / ΖυΖΖ / υΊ ZUOy (QA or cargo). Figure 27 shows an alternative system 210a, which is identical to system 210 in Figure 26, but also includes a ramp 282 adjacent to the second turntable 267. The user can drive the operator platform forklift 224 up the ramp 230, through the first turntable 267, across (or over) the bridge 280, and place the outer loaded pallet half 22 onto the second turntable 267. The user can then reverse the operator platform forklift 224 until it is in a position to place the inner loaded pallet half 22 onto the first turntable 267. The operator platform forklift 224 then reverses further down the ramp 230 out of the way.When both loaded pallets 22 are wrapped and / or complete validation, the rider platform forklift 224 is driven up ramp 230 to lift the inner loaded pallet 22, then through the first turntable 267, then onto (or through) bridge 280 to lift the outer loaded pallet 22. The rider platform forklift 224 then continues through the second turntable 267, down ramp 282 and moves the wrapped / validated, loaded pallet halves 22 to the next station (QA). ΜΛ / Ε / ΖυΖΖ / υΊ ZUOU or charging). Furthermore, both turntables 267 are always independently accessible via one of the ramps 230, 282. For example, full-size pallets could be carried up from each of the ramps 230, 282 by means of the different driver-operated platform forklifts 224 so that the two stations 232 can be used independently. In any 210 or 210a system, the 267 tandem turntables could have a notification system that informs operators which turntable may be faster or readily available upon their arrival to reduce waiting times when all turntables are in use. Optionally, tandem turntables could have a large LCD screen displaying wait times for each turntable station. Alternatively, the operator may be able to receive this information from a device carried by the operator or located on the operator's equipment. The 267 tandem rotating platforms could be controlled via a single interface accessible to the operator while they remain on a piece of equipment. This could increase productivity by saving the time typically spent dismantling a ML / i ζυου piece of equipment and walking to the interface. Optionally, the operator may be able to control the rotating platforms from a device that is carried by the operator or located on the operator's equipment, such as a tablet. The bridge 280 is useful in the installations shown above, where the turntables 267 are positioned above the floor and therefore have upper support surfaces that are elevated above the surrounding floor. However, as an alternative, the turntables 267 can be used in tandem by installing them flush with the warehouse floor. This can be done to reduce the space required to install and use the turntables 267 in tandem. In this configuration, there is no need for a bridge or entry / exit ramps, and the pallets 22 can be accessed from any angle. The turntables 267, ramps 230, 234 and bridges 280 could be modular so that they can be separated and used independently of each other, or added together in configurations to suit the number of platforms 22 on a lift (e.g., one, two or more than two). At certain times of the year, a winery may require a higher yield from a single full-size pallet and MA / iz / zuzz / u 1 ruó» it may be advantageous to use the turntables independently, but at other times of the year there may be a need for higher throughput from the pallet halves and it may be advantageous to use the turntables in tandem. The 267 tandem turntables could also be used with two full-size pallets if the material handling equipment tips are lengthened to accommodate. The design of the 267 turntable can have specialized design changes to allow the 267 turntable to withstand being driven with common material handling equipment used in a warehouse, such as a forklift, electric pallet truck, electric rider platform forklift, and others. In an optional configuration, the 267 turntable can use a hard stop to prevent it from deviating beyond a certain point when being driven. This could be done to protect the load cells used on the 267 turntable or the mechanical components that rotate it. In another embodiment, the 267 turntable could use damping features to reduce the impact force caused by a piece of material handling equipment being driven over the turntable. Figure 28 shows a platform system Modular rotating platform 310 according to another embodiment, which includes the stations 232 of Figure 25. The modular rotating platform system 310 could be used in the supply system 10 of Figure 1. Again, each station 232 includes the tower structure 216 and an associated rotating platform 267. The ramp 230 leads to a first rotating platform 267. The bridge 280 connects the rotating platforms 267. The second ramp 282 can also be used but is not shown. In this configuration, a first fence 320 is placed outside the tower structures 216. A second fence 322 is placed adjacent to the turntables 267 such that the turntables 267 and the tower structures 216 are between the first fence 320 and the second fence 322. Fences 320 and 322 provide protection to the turntables 267 against accidental impacts. Fences 320 and 322 are made of an RE attenuating material to protect the RFID readers 270 (e.g., on the tower structures 216—not visible in Figure 28 but shown in Figure 25) within fences 320 and 322 from any RFID outside of fences 320 and 322. An elevated cross-bridge 324 includes a vertical portion 328 extending upward from the second fence 320. A horizontal portion 326 extends from an upper end of the vertical portion 328 over the ZUOU turntables 267, preferably centered between the turntables 267 up to a crossbar 330 mounted on the tower structures 216. The upper lights 332 are mounted on the horizontal portion 326. A plurality of cameras 368 (preferably four, although only two are visible in Figure 28) are mounted on the vertical portion 328 of the elevated cross-bridge 324. Alternatively, the cameras 368 could be mounted on the second fence 322. The elevated cross-bridge 324 is physically decoupled from the rest of the 310 system to prevent inadvertent camera vibrations. In this configuration, the elevated cross-bridge 324 is fixed directly to the floor. Alternatively, the elevated cross-bridge 324 could be fixed to the ceiling. In this configuration, the cross bridge 324 has a vertical portion 328 with a horizontal portion 326. In other configurations, the cross bridge 324 uses a single vertical element, multiple vertical elements, or a vertical element with a cantilevered horizontal element. The power and signal cabling passes through and is protected by the elevated cross-bridge 324. This prevents tripping hazards and damage to the cables on the floor. Figure 29 shows the system 310 without the fences 320, 322 for illustrative purposes. As shown, the cameras 368 are mounted in a single location that allows viewing of both turntables 267 in tandem. The views of the cameras 368 can be crossed such that the right-hand camera 268 is directed toward the left-hand turntable 267 and vice versa. In this configuration, the cameras 368 are located at the intersection of two circles circumscribed around the axis of the turntables 267. In this configuration, the radius of the circle is equal to the average depth-of-field interval of the camera 368 lens. In another configuration, the 368 cameras could be placed at various points on the elevated cross-bridge 324, the tower structure 216, and / or the fences 320, 322. They could also be mounted on the floor, walls, or ceiling. This strategic placement of the cameras reduces the rotations needed to capture all the required images, and capturing all the required images quickly improves performance capability. The 368 cameras must be positioned at the correct distance, or the lens will not be able to focus. In this mode, the camera is mounted on a permanent fixture relative to the rotating platform 267. This offers ease and speed of installation. It also allows for easily repeatable positioning of the 368 camera. In another modality, the permanent appliance is fixed In another embodiment, a template or model is used to locate the cameras 368. In another embodiment, the floor is marked with a pattern or other means to mark the installation location of the cameras with respect to the rotating platforms 267. In another embodiment, the cameras 368 are fixed directly to the tower structure 216 (as in the above embodiments). Integrating the lights, impact protection, REID dimming, and HMI into a single unit reduces the system's footprint, saving valuable warehouse space. The integrated HMI allows the operator to control both turntables, reducing the total number of stages and increasing throughput. The HMI can be positioned within the operator's reach while on the equipment, enabling control of the turntables without leaving the machine. The elevated crossbridge and integrated fence are designed so that all components can be packed onto a 121.92 cm x 243.84 cm (48 x 96 in) pallet. This allows for less expensive shipping and easier installation. The operation of system 310 is the same as that shown in Figure 25. If the second ramp 282 is added, then the operation of system 310 can be the same as that shown in Figure 27. ivia / t / zuzz / u ι ϶υου In this configuration, the elevated cross-bridge is coupled and held together, but in another configuration it could be welded together on site or adjusted by sliding and secured with pins. In another configuration, the elevated cross-bridge and integrated fences use a camera and light without a rotating or wrap-around platform for use in identifying the contents of a pallet. The turntables, ramps, bridges, integrated fence, and elevated crossbridge could be modular so that they can be separated and used independently of each other or added together in configurations to suit the number of platforms on a lift. At certain times of the year, a warehouse may require higher throughput from a single full-size pallet and it may be advantageous to use turntables independently, but at other times of the year there may be a need for higher throughput from half pallets and it may be advantageous to use turntables in tandem. Tandem turntables could also be used with two full-size pallets if the material handling equipment's forks are lengthened to accommodate them. The value of the modular design is that the system can be configured to operate with a single pallet or can be combined with two full-size pallets. ML / i zouu configure to operate with two pallets (in tandem) to meet performance needs. The system 310 of Figure 28 can be reconfigured into the system 310a of Figure 30 with a single turntable 267. With only the addition of another elevated cross-bridge 324 and the chambers 368, the other turntable 267 and the tower structure 216 could also be used independently. As shown, the first fence 320 of Figure 28 is composed of two first fence sections 320a (one shown in Figure 30), and the second fence 322 of Figure 28 is composed of two second fence sections 322a (one shown in Figure 30). The turntables 67 and 267 in the various embodiments described above are preferably capable of withstanding being driven by a platform forklift 224 or other pallet lifts. A turntable 267 is shown in Figure 31 with the table removed. The turntables 67 could be identical. The table support 290 is connected to a frame 293 by means of a plurality of load cells 292, in this example, three. The load cells 292 suspend the table support 290 and are used to measure the weight of the load on the turntable. Generally, the load cells 292 measure the ML / i ζυο΅ deflection (or tension) and calculate the weight. The challenge of driving on the turntable 267 is the weight of the equipment (e.g., 1360.77 kg (3000 lb)) and the shock loads generated by the equipment during use can overload and damage the load cells 292. Larger load cells could be used, but measurement accuracy would be lost. Figure 32 is a schematic / partial cross-sectional view through a portion of the turntable 267 of Figure 31 adjacent to one of the load cells 292. The load cell 292 is mounted between a bent support 294 on the table support 290 and a bent support 295 on the frame 293. The table support 290 deflects downward under load. In this configuration, to prevent deflection beyond the rated load of the load cells 292 and to maintain measurement accuracy, hard stops 296 are located at a specific height below the table support 290, and displacement is limited so that overloading of the load cells 292 is not possible, but the weight range for normal measurement (e.g., 2.26–907.18 kg (5–2000 lb)) is maintained and reliable operation is ensured. The hard stops 296 can be mounted on the frame 293 as shown or can be mounted on the floor under the table support 290. ML / i ζυου However, the image(s) of the loaded pallet 22 are collected, and then the image(s) are analyzed to determine the SKU of each item 20 on pallet 22 in stage 158 (Figure 2). Any method can be used to identify the SKUs associated with each item on pallet 22. Some examples are described in this document. For instance, images and dimensions of all sides of every possible product, including multiple versions of each SKU, if applicable, are stored on server 14. If multiple still images or videos are collected, then the known dimensions of pallet 22 and the items 20 are used to ensure that each item 20 is counted once and only once. Each SKU has an associated package type and brand. The package type is detected first, and then the brand is sorted to identify which SKU is associated with that product. The package type describes the SKU's packaging. For example, 16OZ CN 1 24 is a package type describing 16-ounce (453.59 g) cans, with 24 cans grouped in one case. A case represents the saleable unit that a store can purchase from the manufacturer. The brand is the beverage flavor and is marketed separately for each flavor. For example, Pepsi, Pepsi Wild Cherry, and Mountain Dew are all brands. Machine learning can be used to detect all package faces on all four sides of the pallet. The packaging type for each item 20 is identified using a machine learning model. Other packaging types include reusable beverage crates, corrugated cardboard trays with translucent plastic wrapping, or fully enclosed cardboard or charcoal boxes. After determining all package types and brands for each package on the pallet, this information can be used to search for the SKU most likely associated with each item 20. After identifying the 20 individual items on each of the four sides of the loaded pallet 22, based on the known dimensions of the 20 items and the pallet 22, duplicates are removed; that is, it is determined which items are visible from more than one side and appear in more than one image. If some items are identified with less certainty from one side but appear in another image where they are identified with greater certainty, the identification with greater certainty is used. For example, if pallet 22 is a half pallet, its dimensions could be approximately 101.6 cm (40 inches) to approximately 121.92 cm (48 inches) by approximately 50.8 cm (20 inches) to approximately 60.96 cm (24 inches), including the metric parameters of 800 mm x 600 mm. Standard-sized beverage cases, beverage cartons, and wrapped corrugated cardboard trays could be visible from at least one side; most could ZUOU can be visible from at least two sides, and some might be visible from three sides. If pallet 22 is a full-size pallet (for example, approximately 121.92 cm (48 in) by approximately 101.6 cm (40 in), or 800 mm by 1200 mm), most products will be visible from one or two sides, but some products may not be visible from either side. The dimensions and weight of hidden products can be determined by comparing them to the picking list. Optionally, stored images (from the SKU files) of SKUs that do not match the visible products can be displayed to the user, who can then manually verify the presence of the hidden products. The SKU count generated by computer vision for this specific pallet 22 is compared against picking list 64 to ensure pallet 22 is built correctly. This can be done before the loaded pallet 22 is wrapped, thus avoiding the need to unwrap it for inspection and correction. If the built pallet 22 does not match picking list 64 (Figure 2, step 162), the missing or incorrect SKUs are indicated to the worker (step 164), for example, via a screen. The worker can then correct the items on pallet 22 (step 166) and restart the validation process. ML / i ζυου (i.e., start new images at stage 156) or wrap the loaded pallet at stage 168. If the loaded pallet 22 is confirmed, a positive response is given to the worker, who then continues wrapping the loaded pallet 22 (step 168). The worker then moves the validated loaded pallet 22 to loading station 34 (step 170). After the loaded pallet 22 has been validated, it is moved to loading station 34 (Figure 1). Referring to Figure 1, the loaded truck 18 carries a hand truck or pallet jack 24 to move the loaded pallets 22 off the truck 18 and into the warehouses 16 (Figure 2, step 172). The driver has a mobile device 50 that receives an optimized route from the distribution center computer 26 or the central server 14. The driver follows the route to each of the plurality of warehouses 16 for which the truck 18 contains the loaded pallets 22. At each warehouse 16, the driver's mobile device 50 indicates which of the loaded pallets 22 (based on their pallet IDs) will be delivered to warehouse 16 (as verified by GPS on the mobile device 50). The driver verifies the correct pallet(s) for this location using the mobile device 50, which checks the pallet ID (RFID, barcode, etc.). ML / i ζυου The driver moves the loaded pallet(s) 22 towards warehouse 16 with the pallet skid 24.
