Description

Technical Field

[0001] The present invention relates to the field of logistics warehousing technology, and in particular to a task distribution and warehouse delivery method, device and system. Background Art

[0002] For orders containing multiple items, the existing technology usually adopts the following processing flow when carrying out order delivery: multiple orders are grouped into a collection list, items are picked according to the items on the collection list, and the picked items are placed in a picking container; after the picking is completed, the items in the picking container are manually sent to the review and distribution station; the review and distribution staff scans the picking container number, obtains the distribution tasks to be reviewed, puts the order frame into the grid of the distribution wall according to the system prompts, and scans the order frame number and grid number to bind the two; after the binding is completed, scan the item code in the picking container, and distribute the items belonging to the same order to the corresponding grid according to the prompts, and then performs the packaging and delivery steps.

[0003] In the process of implementing the present invention, the inventors found that there are at least the following problems in the prior art:

[0004] (1) When the collection order is reviewed and distributed to the order, it is necessary to manually bind the order frame number and the grid number one by one, and the grid number and the order frame number need to be scanned each time the order frame is bound. The operation is cumbersome, labor-intensive, and inefficient.

[0005] (2) When scanning the item code and distributing it to the order, it is necessary to select the item in the picking container and distribute it to n different items in the same order box. It is necessary to perform n item code scanning and n slot scanning to confirm the distribution, which is cumbersome, labor-intensive and inefficient.

[0006] (3) After the order is reviewed, the reviewer needs to manually push the order box to the distribution wall, and the packer will manually move the items in the order box to the packing area. Then, the barcode number of the order box is scanned by a barcode gun for packing, which is time-consuming, labor-intensive, cumbersome and inefficient. Summary of the invention

[0053] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0054] Figure 1 FIG. 1 is a schematic diagram of the main steps of the task distribution method according to the first embodiment of the present invention. Figure 1 As shown, the task distribution method of the first embodiment of the present invention mainly includes the following steps:

[0055] Step S101: According to the set recommendation strategy, recommend sowing positions for the items to be distributed, so as to put the items to be distributed on the distribution wall according to the sowing positions; wherein the recommendation strategy includes storing a single type of items to be distributed at the sowing position. After the picking is completed, the items to be distributed obtained by picking need to be put on the shelves of the grid of the distribution wall. Among them, the distribution wall includes a plurality of unit groups, each unit group includes a plurality of grids, and each grid only stores a single type of items. In the process of shelving, it is necessary to recommend sowing positions for the items to be distributed according to the principle that each grid only stores a certain type of items. The sowing position is the unit group number and grid number of the distribution wall.

[0056] Step S102: Determine whether the items on the shelf of the distribution wall meet the target item types and quantities specified by the task. If the items on the shelf meet the target item types and quantities, bind the storage device identifier, the task identifier of the task, and the corresponding seeding position according to the set matching strategy. Obtain the types and quantities of target items required by each task in the task pool, and compare the types and quantities of the obtained target items with the types and quantities of items already on the distribution wall.

[0057] If the items on the distribution wall meet the types and quantities of the target items specified by some tasks in the task pool, then according to the matching strategy, the storage device identifiers that meet the number of tasks are bound to the task identifiers of each task and the seeding positions of the target items specified by each task. Among them, the matching strategy is used to match tasks that can be distributed to each storage device to bind the tasks to the storage devices. Being able to be distributed means that the items on the distribution wall meet the types and quantities of the target items specified by the task.

[0058] Step S103: Determine the seeding position of the target item of the task bound to the current storage device in the distribution wall, so as to place the items to be distributed in the corresponding seeding position into the current storage device according to the quantity specified by the bound task. According to the types of each target item specified in the task bound to the current storage device, determine the unit group number and grid number of the target item in the distribution wall, and place the items to be distributed stored in the unit group number and grid number into the current storage device according to the quantity of the target item specified by the bound task.

[0059] In the second embodiment, steps S201 to S203 are used to put the items to be distributed on the distribution wall. Steps S204 to S207 are used to bind storage devices and tasks. Steps S208 to S209 are used to complete the distribution of items. Step S210 is used to package the tasks completed by the distribution. The specific implementation is as follows.

[0060] Figure 2 FIG. 1 is a schematic diagram of the main flow of the task distribution method according to the second embodiment of the present invention. Figure 2 As shown, the task distribution method of the second embodiment of the present invention mainly includes the following steps:

[0061] Step S201: The WMS system sends the information of the items to be distributed to the task distribution device. The information of the items to be distributed includes: the picking container number, the basic information of the items to be distributed and the order information. After the picking is completed, the WMS (Warehouse Management System) system sends the above information of the items to be distributed to the task distribution device.

[0062] Step S202: The task distribution device recommends the unit group number and grid number of the distribution wall for the items to be distributed according to the set recommendation strategy, and sends the unit group number and grid number to the WMS system. After receiving the information of the items to be distributed, the task distribution device recommends the unit group number and grid number of the distribution wall for the items to be distributed according to the following recommendation strategy. In a preferred embodiment, the recommendation strategy is as follows:

[0063] (a) Store a single type of items to be distributed in one slot, and items from different batches can be mixed. Items to be distributed with the same SKU (Stock Keeping Unit) are one type. The system records the batch number of each item. If the batch numbers are different, it means that these items belong to different batches. For example, item A may have a batch number of 123 or 234.

[0064] (b) When the slots of the distribution wall are not full, the same items to be distributed are preferentially stored in the same slot of the distribution wall.

[0065] (c) Items belonging to the same task set are stored preferentially in the same unit group of the distribution wall. This strategy allows the distribution to be completed quickly with only one stop of the storage device.

[0066] It should be noted that the recommended strategy must include at least (a), and (b) and (c) are optional.

[0067] The specific implementation of recommending the unit group number and grid slogan of the distribution wall for the items to be distributed is as follows:

[0068] (1) Calculate the overlap between the items to be distributed and the items on the shelves of multiple unit groups of the distribution wall. The calculation formula for the overlap is as follows:

[0069] Overlap degree = Types of items on the shelves in the unit group ∩ Types of items to be distributed / Types of items on the shelves in the unit group

[0070] Formula 1 is illustrated below by an example: Assuming that the types of items on the shelves in a certain unit group of the distribution wall are abcd, and the types of items to be distributed are aberf, and the intersection of the two is ab, then the overlap degree = 2 / 4 = 50%.

[0071] (2) If there are unit groups with a degree of overlap greater than 0, the unit group with the highest degree of overlap is recommended first:

[0072] If there are multiple unit groups with the same or similar overlap, the unit group farthest from the entrance of the storage device is preferred. Figure 5 , the unit group far away from the storage device entrance is the unit group with a large number, so as to avoid the storage device entrance being blocked due to the distribution task.

[0073] In the same unit group, it is preferred to recommend compartments with the same items.

[0074] When there are no available compartments in the same unit group, the compartments of the unit group adjacent to the unit group and far away from the entrance of the storage device are recommended.

[0075] (3) If the overlap with all unit groups is 0, then calculate the correlation between the items to be distributed contained in the task set, and give priority to recommending the unit group containing the items with the highest correlation. Among them, if two items appear at the same time in a task, it means that the two items are associated. The process of calculating the correlation is: count the number of tasks in which the combination of two items appears at the same time in a task, and the number of tasks is the correlation. The following example illustrates: assuming that there are tasks 001 and 002 in the task pool, task 001 includes items abc, and task 002 includes items ab, then the correlation between ab is 2, and the correlation between ac is 1.

[0076] If there are multiple unit groups with the same degree of association, the grid of the unit group farthest from the entrance of the storage device is recommended first.

[0077] Step S203: The WMS system puts the items to be distributed on the distribution wall according to the received unit group number and grid number. After the RF (Radio Frequency Identification) gun of the WMS system receives the unit group number and grid number, the distributor will put the items to be distributed on the distribution wall according to the prompts on the RF gun. The RF gun is a handheld device used for scanning.

[0078] Step S204: The task distribution device determines whether the items on the distribution wall meet the target item type and quantity specified by at least one task. If the items on the shelves do not meet any task, step S205 is executed; if the items on the shelves meet at least one task, step S206 is executed.

[0079] This step is to match the types and quantities of items on the put wall with the types and quantities of target items specified by the task, and determine how many tasks the items on the put wall can satisfy. Here is an example: Assume that the items on the put wall are abcd, and each item is 2 pieces. If there are 4 tasks including abcd, and the number of items is 1 piece, then the number of tasks satisfied by the put wall is 2.

[0080] Step S205: After the task distribution device waits for a set time, step S204 is executed. If the items on the shelves fail to meet any task, the device waits for a period of time and then makes another judgment.

[0081] Step S206: The task distribution device calculates the number of tasks that the items on the shelves meet, takes the number of tasks as the number of storage devices, and executes step S207. If the number of tasks that the distribution wall meets is 2, the number of storage devices required is also 2.

[0082] Step S207: The task distribution device binds the storage device identifier, the task identifier of the task, and the corresponding grid number according to the set matching strategy. According to the items on the distribution wall, select a task that can meet the type and quantity of the target items from the task set, and bind the task to the storage device. If there are multiple tasks selected, you can select a task and bind it to the storage device according to the set matching strategy. The matching strategy here can be random selection, selection in order of task deadlines, etc. For example, there are 10 tasks in the task set, namely Task 1-Task 10, and the items on the distribution wall can meet Task 1 and Task 2, then Task 1 or Task 2 is randomly selected to bind to the storage device. For another example, if the deadline of Task 1 is earlier than the deadline of Task 2, then Task 1 is selected to bind to the storage device.

[0083] When binding task identifiers and grid slogans, tasks can be classified according to whether their deadlines are close to the end of wave production, and different matching strategies can be set for tasks close to the end of wave production and tasks not close to the end of wave production. In the warehousing and logistics scheduling process, arrangements are made according to the "wave" time. For example, there are 8 waves a day, of which 8 to 10 o'clock is a wave, and each wave completes the production operations of multiple tasks. Determine whether the difference between the task deadline and the end of wave production falls within the set time range. The time range can be customized. If it does, the task is a task close to the end of wave production. For example, assuming that the task deadline is 9:40, the end of wave production is 10 o'clock, and the time range is 30 minutes, then the task can be considered a task close to the end of wave production.

[0084] In a preferred embodiment, the matching strategy of binding task identifier and format slogan is as follows:

[0085] (a) Near the end of wave production

[0086] If both a single unit group and a collection group formed by multiple unit groups can meet the types and quantities of target items specified in the task: it is preferred to select the grid of the single unit group to match the target items.

[0087] In the scenario where a single unit group meets the requirements, if there are multiple single unit groups that can meet the target item type and quantity specified in the task: the unit group close to the entrance of the storage device is preferably selected to match the target item. Figure 5 The unit group close to the entrance of the storage device is the unit group with a smaller number.

[0088] In the scenario of group satisfaction, if there are multiple group sets that can meet the target item types and quantities specified in the task: preferably select the group set containing the fewest single unit groups to match the target items. For example, if unit groups 01 and 03 can meet a task, and unit groups 02, 03, and 04 can also meet the task, then unit groups 01 and 03 are matched.

[0089] (b) Not near the end of wave production

[0090] If both a single unit group and a collection group formed by multiple unit groups can meet the target item types and quantities specified in the task: it is preferred to select the grid of the collection group to match the target items.

[0091] In the scenario of group satisfaction, if there are multiple group sets that can meet the target item types and quantities specified in the task: preferably select the group set containing more single unit groups to match the target items. For example, if unit groups 01 and 03 can meet a task, and unit groups 02, 03, and 04 can also meet it, then unit groups 02, 03, and 04 are matched.

[0092] In a single unit group satisfaction scenario, if there are multiple single unit groups that can meet the target item types and quantities specified in the task: it is preferred to select the grid of the unit group far away from the entrance of the storage device to match the target item.

[0093] Step S208: The task distribution device determines the unit group number and grid number of the target item of the task bound to the current storage device on the distribution wall, lights up the electronic tag of the grid on the distribution wall, and displays the distribution quantity. After the storage device and the task are bound, the task distribution device calculates the unit group number and grid number of the target item contained in the task bound to the current storage device on the distribution wall, lights up the electronic tag of the grid, and displays the number of target items in the task as the distribution quantity. For example, if the number of target item 1 is 5, the electronic tag of the grid corresponding to target item 1 is lit and the number 5 is displayed.

[0094] Step S209: The reviewer places the items to be distributed with the unit group number and the compartment number into the current storage device according to the displayed distribution quantity. The reviewer takes the corresponding items from the lit compartments on the distribution wall according to the displayed distribution quantity, places the items into the current storage device, and then takes a picture of the electronic tag, indicating that the distribution and picking is completed.

[0095] Step S210: The review distributor transports the distributed storage device to the packing station for packing. In a preferred embodiment, the storage device is provided with a radio frequency identification (RFID) chip, in which the RFID number is stored, and the packing station is provided with an RFID identifier. After the distributed storage device is transported to the packing station, the identifier automatically identifies the RFID number and sends it to the information system. The information system searches for the task information corresponding to the RFID number (including task number, item number, item quantity, user information, etc.), and then performs packing, without manually scanning the RFID number on the storage device.

[0096] In the second embodiment, the reviewer manually provides storage equipment, completes the distribution of items, and transports the storage equipment to the packaging station, which has high work intensity and low distribution efficiency. In the third embodiment, the task is limited to an order task, and the order contains more than two items. A supply device for automatically supplying storage equipment and a conveying device for transporting storage equipment to the packaging station are provided, which reduces the work intensity of the reviewer and improves the distribution efficiency.

[0097] Figure 3 FIG. 1 is a schematic diagram of the main flow of the task distribution method according to the third embodiment of the present invention. Figure 3 As shown, the task distribution method of the third embodiment of the present invention mainly includes the following steps:

[0098] Step S301: The WMS system sends information about items to be distributed to the task distribution device. The implementation principle of this step is the same as that of step S201.

[0099] Step S302: The task distribution device recommends the unit group number and grid number of the distribution wall for the items to be distributed according to the set recommendation strategy, and sends the unit group number and grid number to the WMS system. The implementation principle of this step is the same as that of step S202.

[0100] Step S303: The WMS system puts the items to be distributed on the distribution wall according to the received unit group number and grid number. The implementation principle of this step is the same as that of step S203.

[0101] Step S304: The task distribution device determines whether the items on the distribution wall meet the target item type and quantity specified by at least one order. If the items on the shelves do not meet any order, step S305 is executed; if the items on the shelves meet at least one order, step S306 is executed. The implementation principle of this step is the same as step S204.

[0102] Step S305: After the task distribution device waits for a set time, step S304 is executed.

[0103] Step S306: The task distribution device calculates the number of orders that the items on the shelves meet, takes the order number as the number of storage devices, and sends it to the supply device through the storage device supply instruction, and executes step S307. The method of calculating the number of orders that the items on the shelves meet is the same as step S205. In the embodiment, the supply device is a frame remover.

[0104] Step S307: The supply device places a corresponding number of storage devices on the conveying device. If the number of orders satisfied by the items on the shelves is N, and N>0, the de-framing machine places N storage devices on the conveying device. In an embodiment, the conveying device may be a conveyor line, and when the conveyor line is not congested, the task broadcasting device notifies the de-framing machine to place N storage devices on the conveyor line.

[0105] In a preferred embodiment, a detection identifier and multiple position identifiers are provided on the conveying device, and the above identifiers are all radio frequency identifiers. Two position identifiers are provided at the conveying device corresponding to the center position of each unit group of the distribution wall, and the distance between the two position identifiers is at least the length of a storage device.

[0106] Step S308: When the conveying device transports the storage device to the identification range of the detection identifier, the detection identifier obtains the storage device identification and sends the storage device identification to the task broadcasting device.

[0107] Step S309: The task distribution device binds the storage device identifier, the order identifier of the order and the corresponding grid number according to the set matching strategy. The implementation principle of this step is the same as that of step S207.

[0108] Step S310: When the conveying device transports the storage device to the identification range of the current position identifier, the current position identifier obtains the storage device identification and sends the storage device identification to the task broadcasting device.

[0109] Step S311: The task distribution device determines whether the unit group of the distribution wall corresponding to the current position identifier has the target item specified by the order bound to the storage device. If so, execute step S312; if not, execute step S315.

[0110] Step S312: The task distribution device sends a stop command to the conveying device, so that the storage device stops at the location of the current position identifier, lights up the electronic tag of the unit group, and displays the distribution quantity. If the storage device at the second position and the storage device at the first position in the unit group have the same items, the electronic tag will display the distribution quantity of the two orders, such as 5; 5.

[0111] Step S313: The reviewer places the corresponding number of items to be distributed into the storage device according to the prompt of the electronic tag, and takes a picture of the electronic tag to send the electronic tag information to the task distribution device.

[0112] Step S314: After receiving the electronic tag information, the task distribution device sends a start instruction to the transport device to make the storage device continue to move forward to the next position identifier, and use the next position identifier as the current position identifier to execute step S310. The task distribution device can also calculate whether there are still items in the slot of the unit group. If so, no processing is performed; if not, the slot status is changed to idle.

[0113] Step S315: The task distribution device determines whether the order distribution and picking is completed. If it is completed, step S316 is executed; if it is not completed, step S317 is executed.

[0114] Step S316: The storage device is transported to the packing station by the conveying device, and the packing process is performed at the packing station. The packing process of this step is the same as the implementation principle of step S210.

[0115] Step S317: Use the next position identifier as the current position identifier and execute step S310.

[0116] It can be seen from the task distribution method of the embodiment of the present invention that the same type of to-be-distributed items are put on the same sowing position of the distribution wall, and then the storage device, the task and the sowing position are automatically bound according to the matching strategy, and then the target items of the specified number of tasks are placed in the storage device, which reduces the operation process and improves the distribution efficiency; the sowing position is recommended based on the overlap, so as to facilitate the recommendation of the unit group and the grid storing the same items as the to-be-distributed items to the user; the sowing position is recommended based on the combination of overlap and correlation, so as to facilitate the recommendation of the unit group and the grid containing the highly correlated items to the user when there is no unit group containing the same items as the to-be-distributed items; the storage device is automatically provided by the supply device and automatically transported to the packaging station by the conveying device, without the need for manual operation, which reduces the labor intensity of the staff and improves the review and packaging efficiency.

[0117] The common processing flow of task delivery is: picking, distribution, review, packaging, and delivery. The task delivery method of the present invention is described below in conjunction with the task distribution method of the embodiment.

[0118] Figure 4 FIG. 1 is a schematic diagram of the main steps of the task outbound method according to an embodiment of the present invention. Figure 4 As shown, the task out-of-stock method of the embodiment of the present invention mainly includes the following steps:

[0119] Step S401: Select tasks that are close to the end of wave production from the task pool to generate a first task set, and select tasks that are not close to the end of wave production to generate a second task set. The tasks in the embodiment are orders. Select orders that are close to the end of wave production as the first task set, and select all orders that are not close to the end of wave production as the second task set.

[0120] Step S402: According to the set picking strategy, tasks that reach the number of available slots in the distribution wall are selected from the first task set and the second task set to generate corresponding picking item sets. When the wave production is about to end, the picking strategy is as follows:

[0121] Select orders with a near deadline from the first task set as the first task subset, and select orders with a non-near deadline as the second task subset; sort the orders in descending order of the number of items in the order, use the items with the largest number of items in the first task subset as seed items, and filter out orders containing the seed items. During the screening process, prioritize orders with fewer types and more items until the number of selected item types reaches the number of available slots in the drop wall, and determine the picking item set. The picking item set includes item numbers and item quantities.

[0122] In an embodiment, the method for determining whether an order is close to the deadline is: determine whether the difference between the deadline time of each order in the first task set and the current time falls within a set time range, which can be customized. If it does, the order is close to the deadline.

[0123] For the orders of the second task subset, if all the items in the order fall into the picking item set, the item quantity of the corresponding items in the picking item set is increased according to the item quantity of the order. For example, there are 4 SKUs abcd in the picking item set, and there are 200 orders that are not near the end of the production wave, of which 20 orders contain all the items that fall into the picking item set abcd, then the item quantity corresponding to the items in these 20 orders is increased to the picking item set.

[0124] When the production is not near the end of the wave, the picking strategy is as follows:

[0125] Sort the items in the order from most to least, take the items with the largest number in the second task set as seed items, and filter out the orders containing the seed items. During the screening process, give priority to orders with fewer types and larger numbers of items until the number of selected item types reaches the number of available slots in the spread wall, and determine the picking item set.

[0126] Step S403: locate the corresponding storage locations of the items in the picking item set, so as to pick the items according to the picking item set. Locate the storage locations of the items in the picking item set in the storage area, generate picking tasks according to the picking container volume and item type and quantity constraints, send the picking tasks to the terminal device of the picker, and notify the picker to pick the items. The implementation process of generating picking tasks is as follows:

[0127] According to the positioning results, the original numbers of the storage locations are renumbered in ascending order; the items corresponding to the positioning results with smaller numbers are placed in the picking container until the picking container is full or all the positioned items have been placed in the picking container, at which point the picking task generation is completed. In addition, there are also restrictions on the types of items that can be stored in a picking container, for example, a maximum of 5 items can be stored.

[0128] Step S404: using the task distribution method, the items to be distributed are placed into the storage device to pack the items in the storage device. The specific implementation process of this step is shown in Example 1, Example 2 and Example 3.

[0129] It can be seen from the task outbound method of the embodiment of the present invention that based on the judgment criterion of whether the wave production is about to end, the corresponding task set is selected from the task pool, and then the picking task is generated in combination with the picking strategy, so as to improve the picking efficiency while meeting the number of available grids on the distribution wall.

[0130] Figure 5 FIG. 1 is a schematic diagram of the structure of a task distribution system according to an embodiment of the present invention. Figure 5 As shown, the task distribution system of the embodiment of the present invention includes: a distribution wall 501, a conveying device 502, a storage device 503 and a task distribution device. The function of the task distribution device is as described above and will not be repeated here.

[0131] The distribution wall 501 includes a plurality of unit groups, each unit group includes a plurality of slots, each slot is provided with an electronic tag, and the electronic tag is used to display the distribution quantity of the slot (i.e., the number of target items specified in the order). In this embodiment, the distribution wall 501 has 4 unit groups, namely unit group 01 to unit group 04, each unit group has 3 slots, each slot only places one kind of item, and one electronic tag supports the display of the distribution quantity of two orders.

[0132] The conveying device 502 is provided with a detection identifier and a plurality of position identifiers. The storage device 503 is placed at the entrance end (i.e. Figure 5The conveying device 502 starts, and when it passes through the detection identifier, the detection identifier obtains the storage device identification; when it passes through the position identifier, the position identifier obtains the storage device identification and receives the start instruction and stop instruction sent by the task broadcasting device to start and stop the movement of the conveying device 502 accordingly. The exit end of the conveying device 502 (i.e. Figure 5 The right end of the packaging table) is connected to the conveyor line ( Figure 5 A position identifier is provided at the center position of each unit group corresponding to the conveying device 502.

[0133] In this embodiment, the 01 identifier is a detection identifier, and the 02-05 identifiers are all position identifiers. The detection identifier is used to detect whether there is a storage device on the conveying device and whether the conveying device is crowded. If the storage device is placed in the designated target area, the storage device is temporarily suspended.

[0134] In a preferred embodiment, a distribution wall 501 is provided on both sides of the conveying device 502, and two front and rear adjacent position identifiers are provided at the center position of each unit group corresponding to the conveying device, and the distance between the two position identifiers is greater than or equal to the size of the storage device 503.

[0135] In another preferred embodiment, the task distribution system may further include: a supply device 504, which is arranged at the entrance end of the conveying device 502 and is used to automatically supply the storage devices 503, that is, to place the storage devices 503 one by one on the conveying device 502.

[0136] The working principle of the task distribution system of the embodiment of the present invention is: picking items from the storage area according to the collection list; putting the picked items to be distributed on the distribution wall, and each grid of the distribution wall stores one type of item to be distributed; the supply device automatically places the empty storage device on the conveying device; the position identifier of the conveying device identifies the storage device, and distributes the items from the distribution wall to the storage device according to the type and quantity of items specified in the order; after the distribution picking is completed, the conveying device transports the storage device to the packing table for packaging.

[0137] Figure 6 FIG. 1 is a schematic diagram of the main modules of the task broadcasting device according to an embodiment of the present invention. Figure 6 As shown, the task broadcasting device 600 of the embodiment of the present invention mainly includes:

[0138] The recommendation module 601 is used to recommend sowing positions for the items to be distributed according to the set recommendation strategy, so as to put the items to be distributed on the distribution wall according to the sowing positions; wherein the recommendation strategy includes storing a single type of items to be distributed at the sowing position. After the picking is completed, the items to be distributed obtained by picking need to be put on the shelves of the grid of the distribution wall. wherein, the distribution wall includes a plurality of unit groups, each unit group includes a plurality of grids, and each grid only stores a single type of items. During the shelving process, it is necessary to recommend sowing positions for the items to be distributed according to the principle that each grid only stores a certain type of items. The sowing position is the unit group number and grid number of the distribution wall.

[0139] Binding module 602 is used to determine whether the items on the shelf of the distribution wall meet the target item types and quantities specified by the task. If the items on the shelf meet the target item types and quantities, the storage device identifier, the task identifier of the task and the corresponding sowing position are bound according to the set matching strategy. The types and quantities of the target items required by the task are obtained, and the types and quantities of the obtained target items are compared with the types and quantities of the items already on the shelf of the distribution wall.

[0140] If the items on the distribution wall meet the types and quantities of the target items specified by some tasks in the task pool, then according to the matching strategy, the storage device identifiers that meet the number of tasks are bound to the task identifiers of each task and the seeding positions of the target items specified by each task. Among them, the matching strategy is used to match tasks that can be distributed to each storage device to bind the tasks to the storage devices. Being able to be distributed means that the items on the distribution wall meet the types and quantities of the target items specified by the task.

[0141] The delivery module 603 is used to determine the sowing position of the target item of the task bound to the current storage device on the distribution wall, so as to deliver the items to be distributed at the corresponding sowing position to the current storage device according to the quantity specified by the bound task. According to the types of each target item specified in the task bound to the current storage device, the unit group number and grid number of the target item in the distribution wall are determined, and according to the quantity of the target item specified by the bound task, the items to be distributed stored in the unit group number and the grid number are delivered to the current storage device.

[0142] In addition, the task broadcasting device 600 of the embodiment of the present invention may also include: a sending module and an obtaining module ( Figure 6 The sending module is used to send the storage device supply instruction to the supply device when the items on the shelf meet the target item types and quantities specified in the task, so that the supply device places the current storage device on the conveying device. The acquisition module is used to acquire the current storage device identifier when the conveying device transports the current storage device to the first target location.

[0143] From the above description, it can be seen that the same type of items to be distributed are put on the same sowing position of the distribution wall, and then the storage equipment, tasks and sowing positions are automatically bound according to the matching strategy, and then the target items of the task are placed in the storage equipment, which reduces the operation process and improves the distribution efficiency; the sowing position is recommended based on the overlap, so that the unit group and grid that store the same items as the items to be distributed are recommended to the user; the sowing position is recommended based on the combination of overlap and correlation, so that when there is no unit group with the same items as the items to be distributed, the unit group and grid where the items with high correlation are located are recommended to the user; the storage equipment is automatically provided by the supply equipment and automatically transported to the packaging table by the conveying equipment, without the need for manual operation, which reduces the labor intensity of the staff and improves the efficiency of review and packaging.

[0144] Figure 7 Schematic diagram of the main modules of the task outbound device according to an embodiment of the present invention. Figure 7 As shown, the task outbound device 700 of the embodiment of the present invention mainly includes:

[0145] The selection generation module 701 is used to select tasks near the end of wave production from the task pool to generate a first task set, and select tasks not near the end of wave production to generate a second task set. The tasks in the embodiment are orders. Orders of waves near the end of wave production are selected as the first task set, and all orders not near the end of wave production are selected as the second task set.

[0146] The selection generation module 702 is used to select tasks that reach the number of available slots in the distribution wall from the first task set and the second task set according to the set picking strategy, so as to generate a corresponding set of picking items. When the wave production is about to end, the picking strategy is as follows:

[0147] Select orders with a near deadline from the first task set as the first task subset, and select orders with a non-near deadline as the second task subset; sort the orders in descending order of the number of items in the order, use the items with the largest number of items in the first task subset as seed items, and filter out orders containing the seed items. During the screening process, prioritize orders with fewer types and more items until the number of selected item types reaches the number of available slots in the drop wall, and determine the picking item set. The picking item set includes item numbers and item quantities.

[0148] For an order of the second task subset, if all items included in the order fall into the picking item set, the item quantity of the corresponding item in the picking item set is increased according to the item quantity of the order.

[0149] When the production is not near the end of the wave, the picking strategy is as follows:

[0150] Sort the items in the order from most to least, take the items with the largest number in the second task set as seed items, and filter out the orders containing the seed items. During the screening process, give priority to orders with fewer types and larger numbers of items until the number of selected item types reaches the number of available slots in the spread wall, and determine the picking item set.

[0151] The positioning picking module 703 is used to locate the corresponding storage locations of the items in the picking item set so as to pick the items according to the picking item set. The storage locations of the items in the picking item set in the storage area are located, and a picking task is generated according to the volume of the picking container and the constraint conditions of the number of item types, and the picking task is sent to the terminal device of the picker to notify the picker to pick the items.

[0152] The delivery and packaging module 704 is used to deliver the items to be delivered to the storage device by using the task delivery device, so as to package the items in the storage device. The items to be delivered are delivered to the storage device in the manner of the first, second and third embodiments, and the items in the storage device are packaged.

[0153] From the above description, it can be seen that based on the judgment criterion of whether the wave production is about to end, the corresponding task set is selected from the task pool, and then the picking task is generated in combination with the picking strategy, so as to improve the picking efficiency while meeting the number of available grids on the distribution wall.
