[0001] The present application is a U.S. National Stage Application under 35 U.S.C. § 371 of International Patent Application PCT/CN2021/083965, filed on Mar. 30, 2021, which itself claims priority to Chinese Patent Application No. 202010832026.8, filed on Aug. 18, 2020 and entitled “ORDER RECHECKING DEVICE, ORDER RECHECKING SYSTEM AND ORDER RECHECKING METHOD”, the disclosures of both of which are hereby incorporated by reference in their entireties.

[0002] The present disclosure relates to the field of logistics technologies, in particular to an order rechecking device, an order rechecking system, and an order rechecking method.

[0003] With the rapid development of e-commerce, the number of daily orders in warehouses is increasing. Before delivery, multiple goods ordered in an order need to be packed into a package, and then are delivered by a delivery staff. A common processing procedure is that a rechecking task list is generated based on several orders, and all goods corresponding to these orders is listed in the rechecking task list. Rechecking operators pick goods according to goods listed in the rechecking task list. At the point, there is a large quantity of goods, and the goods can be transferred to rechecking zones by goods picking vehicles to prepare rechecking. Rechecking goods in warehouses is a key of warehouse operation. A rechecking objective is to distinguish goods listed in rechecking task lists according to orders to together place multiple goods listed in each order. Generally, multiple goods listed in each order are placed into a same turnover box, to make preparations for packing and delivery of the goods listed in each order. As customers have a gradually increased requirement for logistics timeliness, improving rechecking efficiency in warehouses has become a crucial link to improve the efficiency of an overall supply chain.

[0004] In related technologies well known by inventors, there are generally two order rechecking methods:

[0005] In an order rechecking method, an order rechecking system used mainly includes an electronic tag disposed on a turnover box and an RFID (Radio Frequency Identification) reader disposed at a storage location; and the electronic tag on the turnover box, storage location number, and order information are bound separately, and the electronic tag is used to prompt storage location information of corresponding goods.

[0006] In another order rechecking method, each storage location in a rechecking shelf is pasted with a bar code, and each turnover box is provided with the bar code. Before rechecking, storage location bar code information, bar code number on turnover box and order information are bound separately. When goods are scanned each time, storage location number corresponding to the goods is prompted by a display screen, and the goods are placed in a turnover box corresponding to rechecking storage location, and then the storage location bar code is scanned for verification. The above operations stop until all goods are rechecked.

The connecting hole 1111H is applied to a shelf connecting rod of a suspension assembly 125 described below and configured for suspending the shelf unit 110 on a rail 122.

[0103] The baffling part 1113 is disposed in each storage layer and configured to partition the storage layer where the baffling part 1113 is arranged into different storage locations S. As shown in FIG. 1 and FIG. 2, FIG. 5 and FIG. 6, and FIG. 10, in some embodiments, the baffling part 1113 is disposed between two adjacent storage locations S so as to partition the two storage locations, and the baffling part 1113 is disposed in a variable position way to adjust space of the two adjacent storage locations S.

[0104] As shown in FIG. 10, in some embodiments, the baffling part 1113 includes a baffle 1113A, a bottom plate 1113B, and a flanging plate 1113C. The bottom plate 1113B is strip-shaped, the length direction thereof is horizontally placed in a direction from the front to rear of the frame 1111, and the bottom plate 1113B is disposed on the shelf plate 1112 of the storage layer and is moveable along left-right direction. The baffle 1113A stands in the middle of the bottom plate 1113B and fixedly connected to the bottom plate 1113B. The flanging plate 1113C is connected to the front end of the bottom plate 1113B and extends downward from the front end edge of the bottom plate 1113. The bottom plate 1113B is placed on the shelf plate 1112 of the shelving unit 110 and configured for fixing and supporting the baffle 1113A. The flanging plate 1113C and the bottom plate 1113B form a perpendicular angle; the flanging plate 1113C and an edge of the bottom plate 1113B are together disposed on a corresponding intermediate beam 1111D or a transverse end beam 1111B to provide position limitation and fixation.

[0105] The baffling part 1113 is disposed on the shelf plate 1112 and is movable left and right to perform physical isolation on adjacent different storage locations S. In addition, space of each of the adjacent different storage locations S may be also properly adjusted. If space required of part of orders exceeds the volume of the storage location S, the volume of the storage location S corresponding to the order is increased by moving the baffling part 1113, to better fit with space required for goods listed in different orders.

[0106] In this embodiment, each storage layer is provided with only one baffling part 1113. In some embodiments not shown, each storage layer can be provided with more baffling parts 1113 to partition three or more storage locations S for each storage layer.

[0107] In addition, although the foregoing embodiments of the present disclosure only describe the baffling part 1113 on the same storage layer, and the baffling part adjusts space of the storage location by adjusting width of the storage location S. However, in some embodiments not shown, the baffling part may be also disposed between adjacent upper and lower storage locations S, and space of the storage location is adjusted by adjusting height of the storage location S.

[0108] As shown in FIG. 9, in some embodiments, each information interaction apparatus 113 includes two interaction units, namely the first interaction unit 1131 and the second interaction unit 1132. The first interaction unit includes a first display screen 1131A and a first button 1131B, and the second interaction unit includes a second display screen 1132A and a second button 1132B. In addition, each information interaction apparatus 113 may also include a function button set 1133. For example, the function button set 1133 may include a power button, up and down regulating buttons, and the like.

[0109] In this embodiment, each information interaction apparatus 113 includes two interaction units and can implement a single-person operation mode or a dual-person operation mode. In the single-person operation mode, only one interaction unit of the information interaction apparatus 113 is enabled. In the dual-person operation mode, the first interaction unit 1131 and the second interaction unit 1132 are enabled.

[0110] Each information interaction apparatus 113 is provided with two (or more) interaction units, helping to implement order recheck through flexible switching between the single-person operation mode and the dual-person operation mode (when the information interaction apparatus includes more interaction units, there may be a multi-person operation mode with more than three persons) according to different operation strengths, thereby reducing comprehensive cost.

[0111] The setting mode of the information interaction apparatus is not unique, and any information interaction apparatus capable of fulfilling functional requirements during order check can be used. For example, the interaction units of the interaction apparatus 113 may include a display light, a buzzer, a broadcasting apparatus, and other information prompting apparatuses.

[0112] As shown in FIG. 1 to FIG. 4, in some embodiments, the order rechecking device 100 further includes a shelf shifting apparatus 120 configured to drive the shelving unit 110 to move along a predetermined route.

[0113] The shelf shifting apparatus 120 is disposed to drive the shelving unit 110 to move along the predetermined route, so that the shelving unit 110 loaded with goods can be automatically transferred to other operation zones for subsequent operation. For example, the shelving unit can be transferred to the packing zone for packing, or the shelving unit 110 where the goods are unloaded can be automatically transferred from other operation zones to a rechecking zone to recheck a new rechecking task list. Therefore, this increases the automation level and deployment speed of the order rechecking device, helping to improve the recheck efficiency.

[0114] As shown in FIG. 1 to FIG. 4, the shelf shifting apparatus 120 includes a driving apparatus 121 and a rail 122. The driving apparatus 121 is in driving connection to the shelving unit 110. The shelving unit 110 is disposed on the rail 122 and moves along the predetermined route determined by the rail 122. The driving apparatus 121 may be various devices capable of driving the shelving unit 110 to move along the predetermined route, such as a driving motor.

[0115] The shelf shifting apparatus is configured as a combination of the driving apparatus and the rail, and a moving path of the shelving unit 110 does not need to be specially controlled. This helps to accurately control loading or unloading positions of the shelving unit, thereby simplifying a control process.

[0116] As shown in FIG. 1 to FIG. 4, in some embodiments, the rail 122 is a closed rail. An encircling shape of the closed rail may be set according to field requirements. For example, such encircling shape may be an oblong shape, circular shape, etc. Certainly, in some embodiments not shown, the rail may be an open-loop rail, and in this case the shelving unit may reciprocate along the rail.

[0117] A cross-section shape of the closed rail may be set according to carrying requirements. For example, the closed rail may be an H-shaped rail, a grooved rail, etc.

[0118] The rail is configured as the closed rail so that the shelving unit 110 cyclically moves in related operation zones. This helps to reasonably arrange the related operation zones along the closed rail, reduce space occupied by the order rechecking device and the order rechecking system including the order rechecking device in overall, and shorten the route required for completing loading and unloading of goods by the order rechecking device once.

[0119] As shown in FIG. 1 to FIG. 4, the rail 122 may be located above the shelving unit 110 and the shelving unit 110 is suspended on the rail 122, so that the order rechecking device is formed as a suspended rechecking device.

[0120] In some embodiments not shown, the rail 22 may be also located below the shelving unit 110, and the rail 122 provides support for the shelving unit 110.

[0121] In some embodiments, the order rechecking device 100 further includes a transmission device 123, the transmission device 123 is connected between the driving apparatus 121 and the shelving unit 110, and the driving apparatus 121 drives the shelving unit 110 to move via the transmission device 123.

[0122] The transmission device 123 is disposed to more flexibly select and arrange the shelf shifting apparatus 120 and the driving apparatus 121. This also helps to drive a plurality of shelving unit 110 to move by using a same driving apparatus 121 according to set rules, for example, to drive the plurality of shelving unit 110 to move synchronously.

[0123] As shown in FIG. 1 to FIG. 4, in some embodiments, the transmission device 123 includes a driving sprocket (not marked due to hiding from view by the rail), a driven sprocket 1234, and a transmission chain 1233. The driving sprocket is connected to an output shaft of driving apparatus 121. The rotation axis of the driven sprocket 1234 and the rotation axis of the driving sprocket are spaced in parallel. The transmission chain 1233 is mounted on the driving sprocket and the driven sprocket 1234 and arranged along the rail 122, where the shelving unit 110 is connected to the transmission chain 1233.

[0124] As shown in FIG. 1 to FIG. 4, the order rechecking device 100 includes a support frame 130, where the support frame 130 includes a support girder, a lower connecting beam, a connecting beam, a short connecting beam, a motor mounting bracket, a fixing bottom plate, and the like, and is used for supporting the foregoing components of the order rechecking system. The rail 122 is fixedly mounted at the top of the support frame 130, and the driving apparatus 121 and the transmission device 123 are both mounted on the support frame 130 or the rail 122. For example, the shelf shifting apparatus 120 includes a shaft mounting bracket 126, where the shaft mounting bracket is disposed on the support frame 130, a rotating shaft of the driven sprocket 1234 is rotatably mounted on the shaft mounting bracket 126 so that the driven sprocket 1234 is mounted on the support frame 130. The driving apparatus 121 and the driving sprocket are mounted on the rail 122.

[0125] As shown in FIG. 1 to FIG. 4, and FIG. 11 and FIG. 12, the shelf shifting apparatus 120 includes a suspension assembly 125, and the shelving unit 110 is moveably suspended on the rail 122 via the suspension assembly 125.

[0126] As shown in FIG. 11 and FIG. 12, in some embodiments, the suspension assembly 125 includes a guide pulley 1256 fitting with the rail 122, and the shelving unit 110 is suspended on the rail 122 via the guide pulley 1256.

[0127] As shown in FIG. 11 and FIG. 12, the suspension assembly 125 includes a shelf connecting rod 1251, a connecting plate 1252, a bending plate 1253, a fixing rod 1254, a fixing nut 1255, and the guide pulley 1256.

[0128] The shelf connecting rod 1251 fits with the connecting hole 1111H in the frame 1111 of the shelving unit 110 to connect the suspension assembly 125 and the shelving unit 110. After the shelf connecting rod 1251 fits with the connecting hole 1111H, the suspension assembly 125 and the shelving unit 110 may be locked together via a position locking member.

[0164] The following describes specific operation steps of the order rechecking method in the embodiments of the present disclosure with reference to FIG. 13 to FIG. 18.

• • [0165] Step S510: a controller 200 acquires task list information in a rechecking task list including a plurality of orders. A rechecking operator P1 scans the rechecking task list with a hand-held scanning apparatus 300 to acquire task list information such as task list numbers. The rechecking operator P1 can log into the scanning apparatus 300 via an account number. Generally, when picking is performed at a front end, a container number and a rechecking task list number are bound. Thus, after scanning the rechecking task list, the scanning apparatus 300 uploads the task list information to the controller 200, and the controller 200 acquires the task list information in the rechecking task list. The scanning apparatus 300 may be a hand-held device for scanning, and the scanning is mainly performed by identifying bar codes or chips via laser heads, infrared heads, self-sensing devices, and the like provided in the scanning apparatus.
  • [0166] Step S520: the controller 200 matches each of the plurality of orders in the rechecking task list with a storage locations S. The controller 200 acquires shelf information acquired when the scanning apparatus 300 scans a shelf identifier of an idle shelving unit 110. The controller 200 checks a required quantity of shelving units 110 and selects the shelving units 110 according to the quantity of the orders and a quantity of storage locations of the idle shelving unit 110 corresponding to the shelf information. It is determined that whether a quantity of storage locations in the idle shelving unit 110 is greater than or equal to a quantity of the orders in the rechecking task list; under the condition that a determining result is no, more shelving units 110 are waited for releasing the goods, and then it is re-determined that whether a quantity of storage locations in the idle shelving unit 110 is greater than or equal to a quantity of the orders in the rechecking task list; under the condition that a determining result is yes, the shelving unit 110 is selected. The controller 200 matches each of the plurality of orders in the rechecking task list with a storage locations S in the shelving unit 110 selected. The scanning apparatuses 300 scans a storage location identifier 112 corresponding to a storage location S of the shelving unit 110 selected to acquire storage location identification information. The controller 200 matches each of the plurality of orders in the rechecking task list with the storage location S according to the storage location identification information. For example, in this step, the rechecking operator P1 may scan the shelf identifiers of the idle shelving units 110 through the scanning apparatus 300 to acquire shelf bar code numbers, and check a quantity t of required shelving units 110 according to a quantity n of orders and a quantity m of storage locations in the shelving units 110. For example, if the rechecking task list includes n=40 orders and the shelving units 110 corresponding to all shelf bar code numbers include m=12 storage locations S, a required quantity of shelving units is t=4.
  • [0167] Step S530: The scanning apparatus 300 scans an identifier of goods to be rechecked to acquire goods identification information. The rechecking operator P1 scans goods bar codes by using a corresponding scanning apparatus 300. A quantity of rechecking operators P1 and a quantity of corresponding scanning apparatuses 300 may be the same as or less than a quantity of interaction units of the information interaction apparatus. For example, in embodiments as shown in FIG. 1 to FIG. 13, each information interaction apparatus includes two interaction units, and selects a single-person operation mode or a dual-person operation mode for rechecking according to upstream and downstream operation efficiency of an operation site. The single-person operation mode and the dual-person operation mode are flexibly selected to satisfy different operation efficiency. When the overall workload is relatively low, the single-person operation mode is adopted to reduce personnel cost. When the overall workload is relatively heavy, the dual-person operation mode is adopted to match production.
  • [0168] Step S540: The controller 200 controls the information prompting part of the information interaction apparatus 113 corresponding to the storage location S matching with the order listing the goods to be rechecked according to the goods identification information to send out prompt information. In the single-person operation mode, after one rechecking operator P1 scans goods bar codes corresponding to goods, the information prompting part of the information interaction apparatus at the storage location S corresponding to the shelving unit 110 sends out prompt information, for example, a first button light is on. In the dual-person operation mode, after another rechecking operator P1 may simultaneously scan goods bar codes corresponding to other goods listed in the rechecking task list, the information prompting part at the storage location S corresponding to the shelving unit 110 sends out prompt information, for example, a second button light is on. After the rechecking operator P1 scans the goods, the system identifies the order corresponding to the goods and information of the storage location S, and corresponding button lights of the information prompting part are on. In the single-person operation mode, button lights corresponding to the scanning apparatus 300 to scan the goods are on. In the dual-person operation mode, the button light of the information prompting part corresponding to the scanning apparatus held by each rechecking operator P1 is on, the buttons of two information prompting parts may have different colors. For example, the first button light shows white and the second button shows green, or other colors are allocated. The button lights are on to prompt the storage locations S and quantity of the storage locations S corresponding to the goods.
  • [0169] Step S550: Place the goods to be rechecked at the storage location S corresponding to the information interaction apparatus 113 to send out the prompt information. After the information prompting part prompts the storage locations and quantity of the storage locations S corresponding to the goods corresponding to the scanned goods bar codes, the rechecking operator P1 places the goods at the corresponding storage locations S.

[0170] After the goods to be rechecked are placed at the storage locations S corresponding to the information interaction apparatus sending out the prompt information, verification information for verifying that the goods to be rechecked are placed at the storage location S from which the prompt information is sent out is sent to the controller 200. For example, in the single-person operation mode, one rechecking operator P1 presses the first button light corresponding to the information prompting part to acknowledge that the goods have been placed at the proper rechecking storage location S, next goods can be rechecked. In the dual-person operation mode, two rechecking operators P1 respectively press the button light of the information prompting part to acknowledge that corresponding goods have been placed at the proper storage location S, the next goods can be rechecked.

[0171] The foregoing operation is repeatedly performed before| all goods listed in the rechecking task list are rechecked.

• • [0172] Step S560: After the goods to be rechecked listed in the rechecking task list are rechecked, the shelving unit 110 loaded with the goods to be rechecked is transferred to a packing zone.

[0173] As shown in FIG. 18, Step S560 includes: determine whether packing handovers of the orders corresponding to the storage locations S of a corresponding quantity of shelving units 110 facing the packing zone of the order rechecking system are completed.

[0174] A rechecking zone where the rechecking operator P1 operates and a packing zone where a packing operator P2 operates respectively have x shelving units 110, and a quantity of shelving units 110 required by the rechecking task list is t (t≤x). After the rechecking task list is completed, it is determined that whether packing handovers corresponding to the first t shelving units 110 in the packing zone close to the rechecking zone in a rotating direction are completed. Packing handover refers to whether an order is scanned in the packing zone; if scanning the order is completed in the packing zone, packing handover of the goods listed in the order is considered as having completed.

[0175] If packing handovers of the orders corresponding to the storage locations S in the corresponding quantity of shelving units 110 are completed, the order rechecking system automatically rotates the corresponding quantity of shelving units 110.

[0176] If not all packing handovers of the orders corresponding to the storage location S in the corresponding quantity of shelving units 110 are completed, it is determined that whether packing handovers corresponding to the shelving unit 110 closest to the rechecking zone in the rotating direction are completed; if packing handovers corresponding to the shelving unit 110 are completed, the shelf shifting apparatus 120 of the order rechecking system drives the shelving unit 110 to automatically rotate along the rail 122. If packing handovers corresponding to the shelving unit 110 are not completed, the packing operator P2 quickly completes packing handovers of all orders corresponding to the storage locations S of the shelving units 110, and the shelf shifting apparatus 120 of the order rechecking system drives the shelving units 110 to automatically rotate to a designated position along the rail 122 so as to provide an operable shelving units 110 for the rechecking operator P1. The foregoing operations are repeatedly performed to complete packing handovers of all orders corresponding to all shelves participating in rechecking.

[0177] When the shelving unit 110 automatically rotates, the encoder of the driving motor detects whether the shelving unit 110 rotates in place, which includes: the encoder of the driving motor detects whether the shelving unit rotates in place; if the shelving unit does not rotate in place, the driving motor is adjusted to the designated position through the controller; if the shelving unit rotates in place, a next operation can be performed.

[0178] Acquiring a task list information from a new rechecking task list is performed based on the foregoing operations.

[0179] It is determined that whether a quantity of storage locations in the idle shelving units 110 in the rechecking zone is greater than or equal to a quantity of the orders in the rechecking task list, the quantity of the orders in the rechecking task list is compared with the quantity of storage locations in the idle shelving units 110 in the rechecking zone. If a quantity of idle rechecking storage locations is greater than or equal to the quantity of the orders in the rechecking task list, the foregoing rechecking steps are performed before all operations are completed. If the quantity of idle rechecking storage locations is less than the quantity of the orders in the rechecking task list, packing handovers of the orders corresponding to the shelving units 110 are completed and the shelving units 110 are automatically rotated. The foregoing rechecking is performed until the quantity of storage locations in the idle shelving units 110 is greater than or equal to the quantity of the orders in the rechecking task list.

[0180] The rechecking is repeatedly performed until all rechecking task lists are rechecked.

[0181] The order checking method according to the embodiments of the present disclosure has advantages of the foregoing order rechecking device and order rechecking system.
