A paperless delivery order system

[0001] Cross-reference to related applications

[0002] This application claims the priority of a Chinese patent application with the application number 2024103063881 and the title "A paperless delivery order system" filed with the Chinese Patent Office on March 18, 2024. The entire content is incorporated herein by reference. Technical field

[0003] The present invention relates to the field of intelligent order picking, and more particularly, to a paperless delivery order system. Background technique

[0004] E-commerce distribution services refer to the processing of the goods selected in online orders, and the entire process operates from the product storage warehouse, order picking, and delivery to the customer. Among them, the order picking process is a key cost link. The goal is to process each order with the least number of people and the shortest time, and it must be ensured that it is accurate and error-free.

[0005] Traditional order picking lists are divided into the following two categories:

[0006] One is an operation mode where for each order, an independent order picker goes to the product storage location alone to pick the goods and picks the goods according to the picking list.

[0007] One is for a large number of orders, which are integrated into multiple batch groups. On the order picking transport tool, marked positions represent the orders of the batch group. For example, like a "well" character with 9 grids, each grid is an order that needs to be picked. Then the order picker analyzes the quantity of the same type of products in the batch group and manually moves the order picking transport tool to the required goods storage location, and distributes and broadcasts the same type of products into the 9 grids of the relevant orders as the operation mode.

[0008] For the above two conventional order picking methods, the operators need to manually tour each storage location to extract the goods before they can be packaged and transported. Because the products are distributed in the batch storage locations in the warehouse. The operation process requires manually moving the order picking transport tool to the required goods storage location for construction. The effect of this operation method is inevitably low. Because the transportation work is to tour and push the order picking shelves to each goods storage location, the picking cost per order increases, and the order picking efficiency is relatively low.

[0009] Summary of the invention

[0010] The purpose of the present invention is to provide a paperless delivery order system that can improve the order picking efficiency.

[0011] To achieve the above purpose, the technical solutions adopted in the embodiments of this application are as follows:

[0012] In a first aspect, an embodiment of the present application provides a paperless delivery order system, the system comprising: a server, multiple first scanning devices, a carrier, a second scanning device, a picking bin, a conveyor belt, and a picking device. The conveyor belt is provided with multiple first scanning devices, each corresponding to a different picking bin. The server, the multiple first scanning devices, the second scanning devices, and the picking device operate in an Internet of Things (IoT) mode, utilizing a network connection with the server to exchange data. The second scanning device is fixedly provided on the carrier, and the carrier is transported on the conveyor belt.

[0013] The server receives orders initiated by users, determines order information for each order, formulates picking rules based on the order information, and binds the order number corresponding to the order information to the second scanning device according to an Internet of Things communication operation, wherein the picking rules include a picking bin address and a shelf address and a picking quantity corresponding to each to-be-picked item in the order information, and the picking bins correspond to different shelves.

[0014] When each first scanning device scans the second scanning device on the passing carrier, it obtains the order number and picking rules in the second scanning device from the server through the Internet of Things communication operation method, and issues a prompt instruction to the corresponding picking bin and cargo grid picking device to perform on-demand aggregation picking;

[0015] When the first scanning device determines that the corresponding picking bin and cargo grid need to be picked, the server controls the picking device corresponding to the picking bin to pick the goods based on the picking rules, uses the information identifier to read the goods information corresponding to the information of the goods to be picked, and places the goods on the carrying tool when the information of the goods to be picked matches the goods information.

[0016] In an optional embodiment, the server is further configured to determine a picking order corresponding to the goods to be picked in the picking rule;

[0017] Controlling the corresponding picking devices to pick up the goods to be picked based on the picking sequence;

[0018] Control each of the picking devices to place the goods to be picked on the carrying tool in sequence.

When the actual picking position is consistent with the storage location of the product information of the goods to be picked, the server uses the information identifier to determine whether the product information of the picked goods to be picked is consistent. If not, the picking device and the conveyor belt are controlled to be in a stopped state, and an error message is issued.

[0022] In an optional embodiment, the server is further configured to determine, for each of the orders, the customer data, the type of goods information, and the quantity information corresponding to the type of goods information of the order; based on the type of goods information, the server determines the picking warehouse corresponding to the type of goods information and the inventory information corresponding to the picking warehouse; and compiles the customer data, the type of goods information, the quantity information corresponding to the type of goods information, the picking warehouse corresponding to the type of goods information, and the inventory information corresponding to the picking warehouse of the order in a digital format to obtain picking rules.

[0023] In an optional embodiment, different cargo compartments are provided with corresponding picking prompt devices, and the information identifiers are provided at different cargo compartments;

[0024] The server is configured to determine a plurality of target cargo compartments from the plurality of cargo compartments based on the picking rule, and control a picking prompt device corresponding to each of the target cargo compartments to be in an operating state;

[0029] In an optional embodiment, the system further comprises a retesting device;

[0030] The re-inspection device is configured to obtain first product information of each of the products to be picked on the carrying tool after completing the picking of all the products to be picked based on the picking rules, obtain second product information corresponding to the order information corresponding to each of the products to be picked, and compare the first product information with the second product information. When the first product information is consistent with the second product information, it is determined that the re-inspection has passed; when the first product information is inconsistent with the second product information, it is determined that the re-inspection has failed, and the process returns to the re-inspection process and makes corrections.

[0031] In an optional embodiment, the re-inspection device is further configured to obtain the first total weight information of each of the goods to be picked on the carrying tool after completing the picking of all the goods to be picked based on the picking rules, obtain the second total weight information corresponding to the order information corresponding to each of the goods to be picked, and compare the first total weight information with the second total weight information. When the first total weight information is consistent with the second total weight information, it is determined that the re-inspection has passed; when the first total weight information is inconsistent with the second total weight information, it is determined that the re-inspection has failed, and the process returns to the re-inspection process and makes corrections.

[0032] In an optional embodiment, the server is further configured to: determine the goods to be picked for the current order and the goods to be picked for the next order;

[0033] When picking the current goods to be picked, after completing the picking of the current goods to be picked and the conveyor belt has not transported the current carrier to the picking bin corresponding to the next goods to be picked, pre-picking the next order of goods to be picked is performed;

[0034] The operation of pre-picking the goods to be picked for the next order includes:

[0035] The picking device of the current picking bin is controlled to pre-pick the goods to be picked for the next order. When the current carrying tool is transported to the picking bin corresponding to the next goods to be picked, the previous next carrying tool is transported to the current picking bin and becomes the current carrying tool. At this moment, the picking device of the corresponding picking bin places the previously pre-picked goods in the current carrying tool.

[0036] In an optional embodiment, the server is further configured to receive a replenishment instruction; determine the product code of the replenishment goods corresponding to the replenishment instruction, determine the picking bin address and cargo compartment address corresponding to the product code, and control the picking device corresponding to the picking bin address to place the replenishment goods in the cargo compartment in the corresponding picking bin until the incoming quantity of the replenishment goods is reached, wherein the replenishment instruction includes the incoming quantity of the replenishment goods; the server can also control the working status of the picking prompt device corresponding to each of the target cargo compartments, and when the operator completes placing the incoming quantity of the replenishment goods according to the instruction, the server turns off the picking prompt device.

[0062] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0064] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0065] In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear to indicate an orientation or position relationship, they are based on the orientation or position relationship shown in the accompanying drawings, or are the orientation or position relationship in which the product of the invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limiting the present invention.

[0066] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0067] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0068] After extensive research, the inventors discovered that conventional picking methods require operators to manually patrol various storage locations to retrieve goods before packaging and shipping. This is because products are distributed across warehouses in bulk. This operation requires manual transport of picking vehicles to the desired storage locations. This method is inherently inefficient because the manual transport of picking racks to each storage location increases the cost of each order and reduces picking efficiency.

[0069] In view of the discovery of the above problems, this embodiment provides a paperless delivery order system, which can be used to implement a paperless delivery order system. The system includes: a server, a paperless delivery order system, multiple first scanning devices, a carrying tool, a second scanning device, a picking warehouse, a conveyor belt and a picking device. Multiple first scanning devices are set on the conveyor belt. The server and the paperless delivery order system, multiple first scanning devices, second scanning devices and picking devices operate in an Internet of Things mode, using the server to connect to each other and exchange data. The second scanning device is fixedly set on the carrying tool, and the carrying tool is transmitted on the conveyor belt. The server receives orders initiated by users, determines the order information of each order, and formulates picking rules based on the order information, and the order number corresponding to the order information is operated in an Internet of Things communication mode. The operation binds the second scanning device, wherein the picking rules include the picking bin address, shelf address, and picking quantity corresponding to each to-be-picked item in the order information, with each picking bin corresponding to a different shelf. When each first scanning device scans the second scanning device on a passing carrier, it obtains the order number and picking rules from the second scanning device from the server via the IoT communication operation method, issues a prompt instruction to the corresponding picking bin and shelf, activates the picking prompt device and picking device, and performs on-demand aggregation picking. When the first scanning device determines that the corresponding picking bin and shelf need to be picked, the server controls the picking device corresponding to the picking bin based on the picking rules to pick the item, uses an information identifier to read the product information corresponding to the to-be-picked item information, and places the item on the carrier when the to-be-picked item information matches the item information. This can improve picking efficiency and reduce picking costs. The solution provided in this embodiment is described in detail below.

[0070] Please refer to FIG1 , which is a schematic diagram of a paperless delivery order system provided by an embodiment of the present invention.

[0071] The paperless delivery order system includes: a server 1, multiple first scanning devices 3, a carrier 4, a second scanning device 5, a picking bin 6, a conveyor belt 7, and a picking device 8. Multiple first scanning devices 3 are set on the conveyor belt 7, and each first scanning device 3 corresponds to a different picking bin 6. The server 1 and the multiple first scanning devices 3, the second scanning devices 5, and the picking device 8 operate in an Internet of Things mode, using the server to connect to each other and exchange data. The second scanning device 5 is fixedly set on the carrier 4, and the carrier 4 is transmitted on the conveyor belt 7; the server receives orders initiated by users For each order, the order information of the order is determined, and picking rules are formulated based on the order information, and the order number corresponding to the order information is entered into the second scanning device; wherein, the picking rules include the picking bin address, cargo box address and picking quantity corresponding to each item to be picked in the order information, and the picking bin corresponds to different cargo boxes. When each first scanning device scans the second scanning device on the passing carrier, it obtains the order number and its picking rules in the second scanning device from the server through the Internet of Things communication operation method, and issues a prompt instruction to the corresponding picking bin and cargo box picking device to perform on-demand aggregation picking. When the first scanning device determines that the corresponding picking bin and cargo box need to be picked, the server controls the picking device corresponding to the picking bin to pick the goods based on the picking rules, uses the information identifier to read the information of the goods to be picked corresponding to the goods information, and places the goods on the carrier when the information to be picked matches the goods information.

[0072] If there is an error in the picking results, the server will issue a command to stop the picking production line and issue an error message, which means it will sound a horn and flash lights and wait for the picker to fix the problem before restarting the operation.

[0073] To ensure accurate picking, the paperless delivery order system also includes a re-inspection device and a packaging device (see Figure 2). The paperless delivery order system registers the second scanning device on the carrier with a radio frequency reader to dispatch orders. The carrier then enters the conveyor for picking. This demonstration single-line production line features four multi-product picking zones. Multiple first scanning devices are attached to the conveyor, communicating with the second scanning devices on the carrier to accurately stop before the picking zone and accept the placed items. Electronic equipment at the end of the conveyor operates automatically online, detecting the second scanning devices on the carrier and communicating with the IoT server to confirm that the carrier has docked at the picking bin and completed picking. If not, a message is sent or the carrier is automatically withdrawn for special processing. After packaging is completed, the carrier is returned to the starting point of the conveyor for recycling. Pre-shipment re-inspection and packaging then proceed. It should be noted that the first scanning device and the second scanning device can be wireless radio frequency readers or sensors, that is, the first scanning device and the second scanning device are devices capable of acquiring information such as barcodes, QR codes or wireless radio frequency identification systems RFID.

[0074] The container can be a turnover box or a turnover cart, or a packaging container such as a cardboard box, plastic box, or metal box. A second scanning device is attached to the container, waiting to communicate with the first scanning device. After the items are picked and pass re-inspection, the container is sealed, packaged, and shipped.

[0075] When the container is a turnover box, the turnover box is transported on a conveyor belt and collected and picked in a flow-through manner through different picking units corresponding to each picking bin according to picking rules. A second scanning device is set on the turnover box. The second scanning device can identify hardware, that is, a device that can identify barcodes, QR codes, wireless radio frequency identification systems RFID, etc. The identified hardware can be the goods to be picked up. The goods have electronic numbers, or barcodes, or QR code images, so that the second scanning device can identify the corresponding information. When the turnover box arrives at the starting point of the paperless delivery order system, the above-mentioned second scanning device can identify the order information of the paperless delivery order system, where the order information can be displayed in the form of barcodes and image QR codes. When the loading tool is a turnover vehicle, the turnover vehicle can also be equipped with an automatically navigated wheeled mobile device, which uses wireless technology to transmit information. The information can be infrared, 5G, laser, radio waves, magnetic field force, etc., to command the vehicle to directly reach the required picking unit in a track-based or trackless manner to pick up goods; in addition, tracks are also set on the conveyor belt, so as to use the track method to lead the turnover vehicle to the picking unit to pick up goods on demand. When the turnover vehicle moves to the corresponding cargo grid, it can bypass the cargo grid that is not needed in the order and move directly to the corresponding cargo grid in the order for picking, thereby reducing the picking time and improving the picking efficiency.

[0076] Customers can generate orders based on mobile terminals and send them to the server of the paperless delivery order system via IoT communication. Order information can include customer data, product type information, and quantity information corresponding to the product type information. A plurality of first scanning devices are provided on the conveyor belt. When a carrier moves on the conveyor belt, a passing first scanning device scans the second scanning device on the carrier to obtain information about the product type to be picked up in the order. When a first scanning device obtains product type information A to be picked up in the order, the server determines the corresponding cargo compartment in the picking bin based on the product type information A. Different cargo compartments are used to store different types of goods. Based on the cargo compartment corresponding to the product type information A, the server controls the picking device corresponding to the picking bin to move to the corresponding cargo compartment. Different picking devices correspond to different picking bins. The picking device picks up the goods corresponding to the order from the cargo grid, and the information identifier reads the goods information corresponding to the goods to be picked. When the information to be picked matches the goods information, the goods are moved to the carrying tool. When the carrying tool moves to the next first scanning device, the first scanning device obtains the goods type information B that needs to be picked up in the order. The server controls the picking device to move to the corresponding cargo grid based on the cargo grid corresponding to the goods type information B. The picking device picks up the goods corresponding to the order from the cargo grid, and moves the goods to the carrying tool when the information to be picked matches the goods information, until the picking of goods corresponding to all the goods type information in the order is completed.

[0077] It should be noted that different picking bins may be provided at different first scanning devices.

[0078] It should be noted that the server can also customize picking rules based on the order information in the received order, that is, it can customize the picking order of each type of goods information in the order, as well as the picking bin address, cargo box address and picking quantity. When the carrier bound to the order is transported on the conveyor belt, each first scanning device on the conveyor belt scans the order number of the second scanning device of the carrier, and obtains the order number and its picking rules in the second scanning device from the server through the Internet of Things communication operation method. When the picking bin corresponding to the order number is consistent with the picking bin corresponding to the first scanning device, the transportation of the conveyor belt is stopped. The server controls the picking device to pick from the picking bin and cargo box corresponding to the first scanning device based on the picking rules of the order, and uses the information identifier to read the product information corresponding to the information of the goods to be picked, and places the goods on the carrier when the information to be picked matches the product information.

[0079] Picking rules can also instruct multiple orders for the same product to be bundled and sent to the same second scanning device for collective picking to the container. If multiple orders require the same product, the picking method uses the same picking method. The total number of items picked for the same product is summed and transmitted to the second scanning device on the container. The combined quantity is then picked and placed into the container.

[0080] When picking goods, manual picking is also possible. To prevent mispicks, the picking warehouse is equipped with various picking prompts for each compartment, accurately issuing instructions for picking. As shown in Figure 3, a digital meter 202 displays the picking quantity, such as if one item is required. The compartment identification number, or compartment address 203, is also displayed. When turned on, a display light 204 illuminates and sounds 205, providing the picker with clear information about the compartment address. A head-mounted display 219 can also be used to transmit location, image, quantity, and other information via the internet, directly to the picker during picking. Fences 207 or doors 208 can also be provided to prevent and ensure mispicks. During the picking process, each compartment stores its own goods. Goods are identified by reading a barcode 212 attached to the goods using an information identifier 211, or by reading a radio frequency tag 214 attached to the goods using a radio frequency reader 215. Goods are provided with barcodes and radio frequency tools.

[0081] Regarding the picking process, Figure 3 illustrates four items with the picking quantities of 001 and 003 displayed on a digital meter, the gate and door open, the indicator light on, and a sound effect prompting the required picking compartment location. The picker removes the items, scans them, and reads the identification tools on the items to ensure accurate picking. The user can select one or more of these prompting methods, scanning, and reading identification operations as needed, or even select all of them. The compartment design can be single-pass or double-pass. Single-pass allows for the placement and picking of goods from only one side, resulting in low efficiency. Double-pass offers the flexibility of allowing the placement and picking of goods from both sides of the compartment. The double-pass design allows for electromechanical collaborative picking from one side, while the other side of the compartment can accommodate traditional manual picking methods such as playback, thereby rapidly increasing picking productivity.

[0082] When picking in sequence based on picking rules, as shown in FIG4 , the following steps are included:

[0083] S101: The server determines the picking order corresponding to the goods to be picked in the picking rules.

[0084] S102: Controlling the corresponding picking devices to pick up the goods to be picked based on the picking sequence.

[0085] S103: Control each picking device to place each item to be picked on a carrier in sequence.

[0086] In another implementation, the paperless delivery order system can send the order to the server through Internet of Things communication. The server analyzes the order, determines the order information and the picking order based on the order information, and controls the picking device to pick up the goods to be picked from the picking warehouse based on the picking order, and controls each picking device to place each goods to be picked into the carrying tool in turn.

[0087] In another example, a paperless delivery order system sends an order to a server, which analyzes the order, generates a picking sequence based on the order, and controls the carrier based on the picking sequence to control the conveyor belt to move the carrier to the corresponding first scanning device according to the picking sequence. The first scanning device scans the order information in the second scanning device set on the carrier, and then judges the consistency between the picking bin corresponding to the order number of the second scanning device of the carrier and the picking bin of the first scanning device. If the picking bin of the first scanning device is consistent with the picking bin of the second scanning device of the carrier, the server controls the picking device to move to the cargo compartment corresponding to the picking bin at the first scanning device based on the picking rules to pick up the corresponding goods, and moves the goods to the carrier, and controls the carrier to move to the first scanning device of the next sequence to pick up the next goods, until all picking sequences are executed and the picking of the order is completed.

[0088] Picking warehouses can be divided into two categories: Bulk warehouses provide sufficient storage capacity for monthly or annual sales, and can range from thousands to tens of thousands of square meters, depending on the variety and volume of products stored. Their primary function is to serve as replenishment picking warehouses. Picking warehouses are designed to accommodate the volume of orders, product variety, and sales volume during each picking cycle. Replenishment cycles can range from one to two days, or even multiple days.

[0089] The picking warehouse of the present invention is used to pick and distribute goods based on daily to weekly sales volumes. Its area can be less than 10% of a bulk warehouse, allowing pickers to travel short distances within the warehouse, significantly reducing the time spent on product rounds and improving productivity. A short distance is defined as the range within which an adult can ergonomically reach ten steps. The picking warehouse can consist of one or more groups of multi-product picking units, one or more groups of independent product dispatchers, or a combination of one or more picking areas and dispatchers, depending on product size, product type and quantity, picking methods, and available space.

[0090] It should be noted that during manual picking, multiple bins can be set up at each first scanning device. These bins can contain the same or different goods. When picking at each bin, a digital meter can be installed on the bin to display the required picking quantity and the specific number of the corresponding bin. Based on the number of items on the digital meter and the specific number of the corresponding bin, the picking employee can pick the corresponding number of items from the corresponding bin based on the number of items to be picked. After scanning, the items are picked and placed into the container. Different bins can also be equipped with separate digital meters to display the type of goods placed in the bin and the corresponding storage quantity.

[0091] The multi-pick warehouse's capacity and volume are designed based on ergonomics. The number of product types and quantities stored in the picking warehouse is the sum of the number of items stored on each shelf. The width of the cargo area is approximately 7 meters, within 10 steps, while the shelf height is the average adult's height, reaching up to 2 meters. The height can be increased beyond 2 meters as needed, and ladders can be used for operational convenience.

[0092] It should be noted that the picking device can also be an independent cargo dispatcher. When setting up an independent cargo dispatcher, a transport system must be installed. The independent cargo dispatcher is located next to the transport system, and the independent cargo dispatcher and the transport system are positioned at a suitable angle to facilitate the transfer of picked goods to the transport system and their accurate placement on the carriers on the conveyor belt. The independent cargo dispatcher can receive picking instructions issued by the server and dispatch the picked goods to the carriers on the conveyor belt as needed.

[0093] Individual cargo delivery devices are equipped with a storage platform with compartments to organize and store individual items. This platform then serves as a pusher, a device that pushes items onto the conveyor belt as needed. This pusher utilizes servo motors to control power tools such as synchronous belts, chains, slides, spiral coils, and shelves to push items, and is computer-controlled to automate operations on demand.

[0094] During the operation, when an order contains information on multiple types of goods, in addition to picking according to the picking order in the picking rules, you can also pick each type of goods at the same time according to the picking device at the cargo compartment corresponding to each type of goods information in the control order, and move the carrying tool to the corresponding position of the picking device in turn. Use the information identifier to read the goods information corresponding to the information of the goods to be picked. When the information to be picked matches the goods information, control the picking device to place the corresponding goods information in the carrying tool.

[0095] It should be noted that the information identifier may include a scanner, a radio frequency reader, and a camera. Before the picking device places the items to be picked on the carrier each time, the scanner, the radio frequency reader, and the camera detect the item information of the items to be picked.

[0096] When processing multiple orders simultaneously, multiple picking bins can be set up. When there are multiple picking bins, the goods in each picking bin are the same. Each carrier completes picking in a different picking bin. The carrier stops at each picking bin, and the various picking prompt devices based on the picking bin are activated according to the picking instructions on demand, clearly indicating the address of the required picked goods to be picked. The picked goods can be verified by the barcode scanner, that is, the picked goods can be verified by the barcode scanner, thus completing the picking project of the picking bin. At the same time, each picking bin also performs the same picking operation. In this way, each carrier stops at each picking bin in sequence to gather the required picked goods.

[0097] In one implementation method for improving the accuracy of picking goods, each time the picking device picks up goods from the cargo grid, the picked goods can be scanned by a barcode scanner to compare the scanned information with the order information. That is, the picked goods can be verified by the barcode scanner to determine whether the picked goods are accurate. For example, the picked goods can be verified by an information identifier, which can be a barcode scanner.

[0098] In another implementation method, it is also possible to determine the product information of the goods to be picked by the second scanning device, and based on the actual picking position in the product information of the goods to be picked and the storage location of the product information of the goods to be picked, determine whether the product information of the picked goods to be picked is different. If so, the picking device and the conveyor belt are controlled to be in a stopped state, and an error message is issued.

[0099] There are many ways to determine whether the product information of the picked goods to be picked is different. In one implementation method, the information identifier can be used to read whether the information of the goods to be picked in the order is consistent with the information of the goods actually picked. If so, it is determined that the product information of the picked goods to be picked is the same.

[0100] In another implementation, the actual picking location in the information of the goods to be picked is compared with the storage location of the information of the goods to be picked. If they are consistent, it is determined that the goods information of the picked goods to be picked is the same. If they are inconsistent, it is determined that the goods information of the picked goods to be picked is different.

[0101] When determining the cargo grid corresponding to the goods to be picked in the order, a picking reminder device can be set in each cargo grid, and the information identifier is set in different cargo grids. The server determines multiple target cargo grids from multiple cargo grids based on the picking rules, and controls the picking reminder device corresponding to each target cargo grid to be in a working state. When the picking of any target cargo grid is completed, the picking reminder device corresponding to the target cargo grid is controlled to be in a closed state, and the information identifier is configured to detect the goods information of each picked goods.

[0102] The picking prompt device may include display lights, sound effect devices, lighting devices, head-mounted display devices, fences, doors, etc. Since picking can be done manually or automatically based on a picking device, when picking is done manually, the display lights, sound effect devices or lighting devices, head-mounted display devices, fences, and doors at the corresponding cargo compartment can be used to prompt the picker to move to the corresponding cargo compartment to pick up the goods. When picking is done automatically by a picking device, the server can directly control the picking device to move to the corresponding cargo compartment based on the specific location of the cargo compartment to pick up the goods. The server can also send signals to the server through display lights, sound effect lights, and lighting devices. The server determines the corresponding cargo compartment based on the received signals and then controls the picking device to move to the corresponding cargo compartment to complete the picking.

[0103] In the paperless delivery order system of the present application, the conveyor belt includes at least one of the following, or any combination of the following: a single-line conveyor belt, a double-line conveyor belt, a converging-line conveyor belt, a track-type guide path, or a trackless guide path. The conveyor belt includes any one of the following chains or belts for conveying carrying tools; the track-type guide path utilizes wireless control technology to transmit information to guide unmanned handling tools to operate in the direction of the path.

[0104] Still referring to Figure 2, this is a diagram illustrating the operation of a single-line conveyor belt paperless delivery order system. The paperless delivery order system registers the second scanning device 5, i.e., the radio frequency tool, on the carrier 4 with a radio frequency reader to deliver the order. The carrier 4 then enters the conveyor belt 7 to perform the picking. This exemplary single-line conveyor belt paperless delivery order system has four multi-product picking bins 6, with multiple first scanning devices 3 attached to the conveyor belt. The first scanning device can be a radio frequency reader, and its function is to communicate with the second scanning device 5 on the carrier 4, which can also be a radio frequency tool. The first scanning device, located at the end of the conveyor belt 7, operates automatically online, detecting the radio frequency tool on the carrier and confirming with the IoT communication server that the carrier has docked in the picking bin in order to complete the picking. Otherwise, a message is sent or the carrier is automatically withdrawn mechanically for special processing. After packaging is completed, the carrier is returned to the starting point of the conveyor belt for recycling. After the goods are picked up, they are re-inspected by the digital re-inspection device 10 and the physical re-inspection device 11, and the goods are packaged after passing the re-inspection.

[0105] It should be noted that the re-inspection method of the digital re-inspection device is to obtain the first product information of each product to be picked in the carrying tool after completing the picking of all products to be picked based on the picking rules, obtain the second product information corresponding to the order information corresponding to each product to be picked, and match the first product information with the second product information. When the first product information is consistent with the second product information, it is determined that the re-inspection has passed. When the first product information is inconsistent with the second product information, it is determined that the re-inspection has failed.

[0106] In another re-inspection implementation method, the re-inspection method of the physical re-inspection device can be: the re-inspection device is also configured to obtain the first total weight information of each goods to be picked in the carrying tool after completing the picking of all goods to be picked based on the picking rules, obtain the second total weight information corresponding to the order information corresponding to each goods to be picked, compare the first total weight information with the second total weight information, and when the first total weight information is consistent with the second total weight information, it is determined that the re-inspection has passed; when the first total weight information is inconsistent with the second total weight information, it is determined that the re-inspection has failed.

[0107] Figure 5 illustrates the operation of a dual-line conveyor belt paperless delivery order system. The paperless delivery order system pairs carriers 4 for construction. The carriers then proceed to the main or secondary line as needed to pick goods. This demonstration features two parallel lines: the main line is the conveyor belt near the picking bin in Figure 5, and the secondary line is the conveyor belt below the main line. The main line is equipped with multiple first scanning devices 3, which can be radio frequency readers. These devices communicate with second scanning devices 5, which can be radio frequency tools, on the carriers 4. The secondary line is also equipped with multiple first scanning devices, which can also be radio frequency readers. These devices dispatch carriers 4 back and forth between the main and secondary lines as needed. This allows carriers 4 to directly reach the desired picking bin or bypass unneeded bins, reducing carrier run time and increasing production capacity. The radio frequency readers detect when the radio frequency tools on the carriers are in place and activate push forks 9 to move the carriers back and forth between the two lines in a specific direction. The re-inspection device in Figure 6 includes a digital re-inspection device 10 and a physical re-inspection device 11. After the goods pass the re-inspection, they are packaged. The container is transported back to the starting point of the conveyor belt via the transport device 12 for recycling.

[0108] Figure 6 illustrates the operation of a paperless order delivery system using converging conveyor belts. The system includes multiple conveyor belts 71, 72, 73, and 74. Each of these conveyor belts is equipped with multiple first scanning devices, and a digital re-inspection device 10 and a physical re-inspection device 11 are located at the end of conveyor belt 74. To allow carriers to travel between the multiple conveyor belts, a transport device, or diverter, is required. This device guides carriers 4 directly to the picking bins for on-demand converging picking. Each picking bin 6 is equipped with balanced transport facilities to guide carriers to pick. Upon completion, the diverter redirects the carriers to the next picking bin. Alternatively, the diverter remains unchanged and continues directly to the next conveyor belt, bypassing bins that do not require picking until the picking is complete. The arrows on the conveyor belts in the figure indicate the paths along which carriers are guided. The convergence point of each transport facility is the diverter, which turns left or travels straight ahead.

[0109] When the conveyor belt is a double-line conveyor belt, a converging line conveyor belt or a rail-guided path conveyor belt, the server determines the address of the picking warehouse for the type of goods to be picked corresponding to the picking rules based on the picking rules of the order; the server determines the operation route of the carrying tool based on the address of the picking warehouse for the type of goods to be picked, wherein the double-line conveyor belt, the converging line conveyor belt or the rail-guided path conveyor belt guides the operation of the carrying tool; whenever the first scanning device of each picking warehouse identifies whether the order of the second scanning device needs to be picked, if so, the conveyor belt stops picking, and if not, the diverter of the conveyor belt bypasses the picking warehouse that does not need picking and advances to the next picking warehouse or to the re-inspection operation.

[0110] As shown in Figure 7, a demonstration of the operation of a trackless paperless delivery order system is shown. The paperless delivery order system 2 uses a radio frequency reader to import the order information of the order into the second scanning device 5 of the carrier 4. The carrier can be an unmanned transport tool, and the second scanning device on the carrier can be a radio frequency tool. The order is received based on the second scanning device. In addition to transmitting orders based on a radio frequency reader, the paperless delivery order system and the second scanning device can also transmit orders through infrared, 5G, satellite navigation, radio waves such as radar, magnetic fields, cameras, etc. The server guides the carrier 4 to operate in the direction of the path shown in the figure. The unmanned transport tool can directly reach the picking unit corresponding to each picking warehouse, and the first scanning device installed at each picking unit scans the order information in the second scanning device on the carrier. Based on the order information, the server controls the corresponding picking device to pick the goods. Trackless routes require pre-planning, digital program coordination, and wireless control. They follow operational rules such as one visit per bin for picking, or two visits per bin for picking. The goal is to complete on-demand gathering and picking within the shortest path and time. Finally, orders are re-inspected by digital and physical inspection devices before shipment and delivery. Packing takes place after passing the re-inspection.

[0111] The paperless delivery order system registers orders with a second scanning device on an automated guided vehicle (AGV) using a radio frequency reader. Wireless control technologies such as infrared, 5G, satellite navigation, and radio waves such as radar, magnetic fields, and cameras are used to transmit information to guide the AGV along its route. The AGV can be a shuttle vehicle that matches orders. The shuttle vehicle can directly access each area and communicate with the first scanning device at each picking area (i.e., the facility) through IoT operations, stopping to perform on-demand consolidation. Trackless routes require pre-planning, digital program coordination, and wireless control. Picking operations follow a one-area-one-visit, two-area-two-visit, or other operational rules. The goal is to complete on-demand consolidation in the shortest possible time. Finally, pre-shipment inspection and packaging are performed, and the vehicle is returned to the starting point of the transport equipment for recycling.

[0112] Figure 8 shows a demonstration of both track-based and trackless routing. This demonstration introduces four picking bins: Picking Bin 61, Picking Bin 62, Picking Bin 63, and Picking Bin 64. Eight different routing options allow customers to follow picking instructions and directly reach the desired picking bins to pick items. The following examples represent only a portion of the routing and are not exhaustive.

[0113] Demonstration route a for carrier No. 1 is through picking bin 61, picking bin 62, picking bin 63, and picking bin 64. Each picking unit activates digital media to lead the precise and on-demand gathering picking project.

[0114] The No. 2 container demonstration route only goes to picking warehouse 61, where it gathers picking projects precisely and on demand according to digital media guidance. After completion, it goes directly to re-inspection and packaging before shipment.

[0115] The No. 3 container demonstration route c only goes to the picking warehouse 61, and then to the picking warehouse 62, according to the digital media guidance of precise on-demand gathering of picking projects. After completion, it goes directly to the re-inspection and packaging before shipment.

[0116] Demonstration route d for carrier No. 4 goes directly to picking bin 62, and then to picking bin 63. It gathers picking items precisely and on demand, guided by digital media. After completion, it goes directly to pre-shipment inspection and packaging.

[0117] The No. 5 container demonstration route e goes directly to the picking warehouse 63, and then to the picking warehouse 64. According to the digital media guidance, the picking project is accurately gathered on demand. After completion, it goes directly to the re-inspection and packaging before shipment.

[0118] Demonstration route f for carrier No. 6 goes directly to picking bins 62, 63, and 64, where it gathers picking items precisely and on demand, guided by digital media. Upon completion, the picking process proceeds directly to pre-shipment inspection and packaging.

[0119] Demonstration route g for carrier No. 7 is to go to picking warehouse 61, then detour to picking warehouse 63. Following the guidance of digital media, the picking process is precisely and on-demand. After completion, it goes directly to pre-shipment inspection and packaging.

[0120] The demonstration route h of the No. 8 container is to go directly to the picking warehouse 62, then detour to the picking warehouse 64, and gather the picking project according to the digital media's guidance and on-demand precision. After completion, it will go directly to the re-inspection and packaging before shipment.

[0121] The paperless delivery order system provided by this application can also be applied to supermarkets. As shown in FIG9 , it is a demonstration of a paperless delivery order system for supermarkets. Supermarkets centrally purchase and manage goods, providing a diverse range of goods for the public to purchase on demand. In this application environment, the carrying tool 4 is a purchasing cart. First, the customer creates an order, i.e., a purchase order. The client sends the purchase order to the server, which analyzes the required goods and selects a picking unit. Wireless control technology then transmits the required picking route and shelf location to guide the purchasing cart to the picking unit. Whenever the purchasing cart approaches the first scanning device installed in the cargo compartment, the required shelf indicator light automatically turns on to provide the customer with accurate picking information. After the order is picked, the verification process and payment are carried out.

[0122] As shown in Figure 10, a single-line conveyor production line is combined with manual operations. A paperless delivery order system transmits orders to the conveyor and performs manual operations separately, allowing manual operation on one side of the conveyor and automatic operation on the other. This allows for increased picking productivity to meet demand at any time. In the event of discrepancies in picking results, the server issues a command to stop the picking line and issues a signal, such as a siren and flashing lights, waiting for the picker to fix the problem before restarting. Each shelf is equipped with various picking prompts to accurately indicate the required picking instructions: a digital meter to display the picking quantity, such as if one item is required; shelf identification numbers; and indicator lights that illuminate and sound when activated to confirm the shelf location to the picker. A head-mounted display can also be used to transmit location, image, quantity, and other information via the internet directly to the picker during picking. The use of barriers or gates can also prevent and ensure that incorrect picking is avoided. During the picking process, each shelf stores its own products. Product identification involves using a scanner to read the barcode on the product, or a radio frequency reader to read the radio frequency tag on the product. The product is labeled with a barcode and a radio frequency tag. The shelf design can be single-pass or dual-pass. A single-pass design allows for loading and unloading of goods from only one side, resulting in low efficiency. A dual-pass design allows for loading and picking from both sides of the shelf. This allows for electromechanical collaborative picking on one side of the shelf, while traditional manual picking (e.g., playback) is performed on the other side, rapidly increasing picking productivity. According to the aforementioned on-demand aggregation picking rules, real-time instructions are issued on demand, directing carriers on the on-demand aggregation picking transport system to the corresponding picking bins for picking. Whenever a second scanning device on a carrier communicates with a first scanning device equipped with multiple IoT functions on the on-demand aggregation picking transport, the server issues real-time instructions to the various picking prompt devices in the corresponding picking bins according to the picking rules, activating their prompting functions to ensure accurate picking of the specified product type according to the picking instructions.

[0123] Figure 11 illustrates an operational demonstration of the on-demand, aggregated picking method. This method involves transferring goods from picking bins to containers according to preset picking instructions using automated or manual picking rules. Automated picking involves IoT technology issuing commands to mechanically activate independent product delivery devices within each picking bin, or perhaps mechanically and precisely executing picking operations. Manual picking, on the other hand, requires sensory prompts, specifically digital media-based, multi-pick prompts installed within each picking bin, to provide prompts and eliminate the need for human interaction. Both methods involve sequentially placing the selected goods, specifically the type and quantity, within the corresponding containers to complete the process. Consequently, both methods effectively eliminate the need for physical order documents or electronic order information devices to assist in picking. The paperless delivery and picking order system transmits e-commerce orders via an internet cloud service platform to a server, where digital on-demand aggregate picking instructions are generated. Using a radio frequency reader, a single carrier picking rule is assigned. This rule is registered on the carrier and then scanned by a second scanning device to complete the paperless distribution of on-demand aggregate picking orders. Just-in-time conveyors are available in various designs, including single-lane, dual-lane, convergent-lane, track-based, and trackless, to accommodate the picking operation method. Picking operations involve transferring goods from the picking bin to the carrier according to preset picking instructions, using either automatic or manual picking rules. Picking can be fully automated, fully manual, or a hybrid of both, enabling production line operations. A head-mounted display (HMD) can also be used to transmit location, image, and quantity information via the internet directly to pickers. The picking bin design can be divided into multi-product picking areas and independent product dispatchers. Multi-product picking areas can be manually or automatically, with robots picking goods from the picking area or pickers. Independent cargo delivery devices are equipped with transport equipment installed in segmented partitions to sort and push goods onto containers as needed. Alternatively, inclined spacers are installed on rotating transport equipment to arrange goods, and pushers rotate the inclined spacers to push goods onto containers. Alternatively, goods are arranged on shelves on a conveyor belt, and mechanical devices such as manipulators are used to extract and transfer goods to containers. A multi-cargo picking area or independent cargo delivery device is located next to the picking and transport system, in line with the selected picking construction method. Multiple first scanning devices are installed on the conveyor belt, and their function is to communicate with second scanning devices on the container. Whenever the first scanning device senses the second scanning device, the transport device immediately stops, allowing the container to accurately stop in front of the independent cargo delivery device or the multi-cargo picking area to receive the selected goods. The recycling of carriers delivers picking orders to the pre-set picking and transportation system. The carriers can be divided into turnover boxes or turnover vehicles. After packaging, the carriers are returned to the paperless distribution system to gather picking orders on demand for reuse. Multi-stage picking, accurate picking process management and quality control rely on dual-function picking instructions. The picking production line server analyzes the order type, quantity and type address and converts them into digital information.In terms of picking process management, each timely, on-demand picking operation is executed using digital media such as sound effects, lighting, head-mounted displays, electronic equipment, machinery, or physical actions such as manual labor. Following these instructions, clear physical information—the address of the picking bin and a digital table—guides precise picking. Furthermore, electronic equipment in the transport system precisely delivers the carrier to the picking bin for receiving and selecting goods. Regarding quality control, digital media, electronic equipment, and mechanical equipment utilize the Internet of Things to issue instructions and provide feedback on the real-time, sequential status of picking operations. Continuous monitoring ensures accurate picking. This physical picking method uses at least one, multiple, or all-in-one picking instructions. Electronic equipment at the end of the transport system operates automatically online, detecting the radio frequency (RF) on the carrier and communicating with the IoT server to confirm that the carrier has docked at the picking bin and completed the picking process. If not, a message is sent or the carrier is automatically mechanically withdrawn for special processing. Pre-shipment inspections are conducted here, using RF readers, barcode scanners, or scales to confirm the correct type and quantity of goods. Finally, packaging is performed before shipment. After packaging, the carrier is returned to the starting point of the transport system for a new dispatch picking order, allowing for recycling of the carrier, achieving a green and environmentally friendly picking process.

[0124] In order to speed up the picking efficiency, the server is also configured to: when picking the current goods to be picked, after completing the picking of the current goods to be picked and the conveyor belt has not transported the current carrier to the picking bin corresponding to the next goods to be picked, pre-picking the next order of goods to be picked is performed. The pre-picking of the next order of goods to be picked includes: controlling the picking device of the current picking bin to pre-pick the next order of goods to be picked, and when the current carrier is transported to the picking bin corresponding to the next goods to be picked, the previous next carrier is transported to the current picking bin to become the current carrier, and at this moment the picking device of the corresponding picking bin places the previously pre-picked goods in the current carrier.

[0125] Current Carrier: This refers to the carrier currently parked in the picking bin, awaiting the placement of picked items. There are carriers queued after the "Current Carrier." When the "Current Carrier" is sent to the next picking bin, the queued carrier becomes the "Current Carrier," awaiting the placement of previously picked items.

[0126] When picking the current goods to be picked, after completing the picking of the current goods to be picked and the conveyor belt has not transported the current carrier to the picking bin corresponding to the next goods to be picked, the operation of pre-picking the goods to be picked of the target order is performed, wherein the target order is any order among the subsequent orders of the current order; the operation of pre-picking the goods to be picked of the target order includes: controlling the picking device of the current picking bin to pre-pick the goods to be picked of the target order, and when the current carrier is transported to the picking bin corresponding to the next goods to be picked, the earlier next carrier is transported to the current picking bin to become the current carrier, and at this moment the picking device of the corresponding picking bin places the earlier pre-picked goods in the current carrier.

[0127] When replenishing goods in the picking bin, the server is further configured to receive a replenishment instruction; determine the product code of the replenishment product corresponding to the replenishment instruction, determine the picking bin address and storage compartment address corresponding to the product code, and control the picking device corresponding to the picking bin address to place the replenishment product in the corresponding storage compartment in the picking bin until the incoming quantity of the replenishment product is reached, wherein the replenishment instruction includes the incoming quantity of the replenishment product. The server can also control the working state of the picking prompt device corresponding to each target storage compartment, and when the operator completes placing the incoming quantity of the replenishment product according to the instruction, the server turns off the picking prompt device.
