Hereinafter, each step of the picking task processing method of this embodiment will be described in more detail along with the attached drawings and examples.

Figure 1 is a flowchart showing a method for processing a picking task according to an exemplary embodiment of the present invention.

Referring to Figure 1, the processing method of the picking task includes the following steps:

Confirming the location information of the storage location to which the product in the order information belongs (S102);

According to the SKU dimension of the product in the storage location, merging the location information to create a picking task (S104);

According to the attribute information of the picking task and the number of products in the order information, selecting the products in the storage location into the first picking container or the second picking container (S106);

A step (S108) of putting the goods in the first picking container into the introduction and distribution device, and the introduction and distribution device distributing the articles and transmitting them to the rechecking device; and

Inserting the items in the second picking container into the re-checking device (S110).

According to the above-described embodiment, the location information of the storage location to which the product in the order information belongs is determined, and the location information is merged according to the SKU (Stock Keeping Unit) dimension of the product in the storage location to create a picking task, According to the attribute information of the picking task and the number of products in the order information, the products in the storage location are selected into the first picking container or the second picking container, the products in the first picking container are put into the introduction and distribution device, and the introduction and distribution device is used to store the products. can be distributed and transmitted to the rechecking machine, and by putting the items in the second picking container into the rechecking machine, picking time is reduced, picking density is increased, processing efficiency of the picking task is improved, and labor costs are further reduced.

According to an exemplary embodiment of the present invention, by selecting products according to the SKU dimension for a plurality of types of picking tasks corresponding to one storage location and classifying the products from the perspective of the picking container, the number of times the picking task is performed reduces, increases the efficiency of picking tasks, and reduces labor costs.

According to an exemplary embodiment of the present invention, all items waiting to be sorted in a storage location are selected, location information is merged according to the SKU dimension of the items in the storage location, a picking task is created, and multiple identical SKUs in the same storage location are ordered. After matching with the location information, merging them into one picking task improves the picking density of the picking task.

According to an exemplary embodiment of the present invention, different containers are classified according to the number of items in the attribute information and order information of the picking task, and further, different subsequent production processes are performed according to the different containers, such as overlapping sorting steps and Reduces distribution steps and further improves shipping efficiency.

According to an exemplary embodiment of the present invention, when the number of products in the order information is plural, the products in the storage location are selected into the first picking container, the products corresponding to several orders are placed in the first picking container, and the first picking container is stored in the first picking container. The goods in the picking container are transported to the introduction and distribution machine, the order information of the goods is bound to the re-confirmation desk, and the matched items are transported to different re-confirmation desks, and after re-confirmation, they are packaged and shipped.

According to an exemplary embodiment of the present invention, when the number of items in the order information is one, the items in the storage location are selected into the second picking container, and there is no need to perform an introduction and distribution process on the items in the second picking container. By directly performing the integration re-confirmation and packaging process, the picking process time is reduced and the efficiency of the picking task is improved.

According to an exemplary embodiment of the present invention, picking efficiency is improved by distinguishing between two different picking containers in a picking operation, that is, sorting items of the same SKU in the same storage location through a first picking container and a second picking container. improve

As shown in Figure 2, the processing method of the picking task further includes the following steps:

Determining the number of times the picking device used to load the first picking container and the second picking container receives a picking task (S202);

Step (S204) of determining whether the number of times is less than or equal to a preset number, performing step (S206) if less than the number of times, and performing step (S208) if not;

If it is determined that the number of picking tasks is less than the preset number, determining the aisle with the highest picking density as the waiting aisle for picking (S206); and

If it is determined that the number of picking tasks is greater than the preset number, the next aisle of the aisle where the picking device is located is confirmed as the waiting aisle for picking (S208).

According to the above-described embodiment, by determining the number of times the picking device used to load the first picking container and the second picking container receives a picking task, the location of the picking device in the inventory area and the picking progress can be determined. there is. If it is determined that the number of picking tasks is less than the preset number, the aisle with the highest picking density is determined as the waiting aisle for picking. At this time, since there are few items in the picking container, the picking device proceeds with picking along the aisle with the highest picking density, thereby increasing the picking density. If the number of picking tasks is determined to be greater than the preset number, the aisle next to the aisle where the picking device is located is confirmed as the waiting aisle for picking, preventing picking devices from going through duplicate picking paths and picking path conflicts between multiple picking devices. It is advantageous in lowering the probability of and overall improves the processing efficiency of the picking task.

As shown in Figure 3, the picking task processing method further includes the following steps.

If it is determined that the number of picking tasks is greater than the preset number, determining whether there is a storage location for the article in the first aisle where the picking device is located (S302);

According to one embodiment of the present invention, the preset number of times may be 1.

If it is determined that there is no storage location in the first aisle where the picking device is located, determining the second aisle, which is the closest aisle to the first aisle, as the waiting aisle for picking according to the code order of the aisle (S304); and

If it is determined that there is a storage location in the second aisle, a step of confirming the second aisle as a picking standby path (S306).

According to the above-described embodiment, when it is determined that the number of picking tasks is greater than the preset number, it is further determined whether there is a storage location for the article in the first aisle where the picking device is located, and the picking task in the first aisle is completed; If it is determined that there is no storage location in the first aisle where the picking device is located, the second aisle, which is the closest aisle to the first aisle according to the aisle code order, is confirmed as the waiting aisle for picking, and the storage location is placed in the second aisle. If it is determined that there is, the second aisle is determined as the waiting aisle for picking, thereby shortening the picking path, reducing the time required for the picking task, and improving the efficiency of the picking task.

As shown in Figure 4, according to the attribute information of the picking task and the number of articles in the order information, the step of selecting the articles in the storage location into the first picking container or the second picking container includes the following steps:

Confirming attribute information of the picking task (S402);

Determining the sorting priority according to the attribute information of the picking task (S404);

Step S406 of determining whether the number of items is less than or equal to the preset number of items, performing step S408 if less than the number of items, and performing step S410 if not;

If it is determined that the number of products is less than the preset number of products, sorting the products into a second picking container according to the sorting priority level (S408); and

If it is determined that the number of products is greater than the preset number of products, sorting the products into the first picking container according to the sorting priority level (S410).

According to the above-described embodiment, the speed of delivery of orders with high delivery timeliness is improved by determining the attribute information of the picking task and determining the sorting priority level according to the attribute information of the picking task. Specifically, it is determined whether the number of products is less than the preset number of products, and if it is determined that the number of products is less than the preset number of products, the products are sorted into the second picking container according to the sorting priority level, and the number of products is less than the preset number of products. If it is determined to be large, the items are sorted into the first picking container according to the sorting priority, so that not only can items of the same SKU in the same storage location be sorted from the perspective of the picking container, but also sorted according to the sorting priority for various order tasks. By selecting items, we improve the timeliness of order shipment.

As shown in Figure 5, the step of determining the sorting priority according to the attribute information of the picking task includes the following steps:

Determining the first priority level according to the number of items waiting to be picked in the picking task (S502);

When it is determined that the number of items waiting to be picked is the same, determining the second priority level according to the lot time of the picking task (S504); and

When it is determined that the lot time of the picking task is the same, the third priority level is determined according to the order reception time of the picking task (S506).

According to the above-described embodiment, after determining the priority level among all items waiting to be sorted by the first priority level, the second priority level and the third priority level may no longer be determined. If there are goods of the same first priority class, the second priority class will continue to be determined, and if the second priority class can determine the priority class among all the goods awaiting sorting, there is no need to determine the third priority class. . If there are goods of the same first and second priority classes, the third priority class will continue to be determined; if there are goods of the first, second and third priority classes that are all the same, Sorting may be performed in a random manner, or may be performed according to the volume of articles waiting to be sorted and the remaining volume of the sorting container. For example, in one storage location, small-volume items may be selected first.

As shown in Figure 6, the processing method of the picking task further includes the following steps:

Confirming difference information between the selected product and the product in the order information according to the picking result of the first picking container and the picking result of the second picking container (S602);

The picking backlog of items within the difference information ( ) Confirming information (S604);

Confirming order type information included in order information (S606); and

A step of creating additional picking tasks according to the picking backlog information and order type information (S608).

According to the above-described embodiment, the difference information between the selected product and the product in the order information is determined according to the picking result of the first picking container and the picking result of the second picking container, and the picking backlog information of the product in the difference information is determined. , By confirming the order type information included in the order information and further creating additional picking tasks according to the picking backlog information and order type information, the accuracy of the additional picking tasks is improved and the processing efficiency of the picking tasks is improved.

As shown in Figure 7, the step of creating an additional picking task according to the picking backlog information and order type information includes the following steps:

Determining the picking backlog of each type of order task according to the picking backlog information (S702); and

A step of creating an additional picking task for the order task according to the size relationship between the difference information and the picking backlog (S704).

According to the above-described embodiment, the picking backlog of each type of order task is determined according to the picking backlog information, and an additional picking task is created for the order task according to the size relationship between the difference information and the picking backlog, thereby adding Improves the accuracy and timeliness of picking tasks.

According to an exemplary embodiment of the present invention, a single item ( ) Two containers corresponding to each order and multiple items are placed, and the sorting worker receives and sorts all items waiting to be sorted in the entire storage location at once, and sorts the items according to the page guidance information on the portable terminal. Put it in a container. In addition, in the picking process by the sorting operator, there is no need to install a separate picking type. When the container is full, input processing is performed to immediately put the container into the line, and after the input processing, the next picking task is bound to the corresponding container. do.

As shown in Figure 8, the processing method of the picking task of the present invention includes the following steps:

Sending the order to the flow picking task pool (S802);

A step in which a sorting worker receives a picking device from a portable terminal (S804);

A step of binding the container after input and a new picking task (S836).

As shown in Figures 9, 10, 11, 12, 13 and 14, corresponding to the embodiments of the above-described method, the present invention also provides a picking method that can be used to perform the embodiments of the above-described method. Provides an inventory unloading platform for tasks. A prerequisite of the present invention includes sending a picking task to flow select single-item orders and multi-item orders to the picking task pool. The specific process is as follows.

Step 1: The picker logs into the picking interface of the portable terminal and clicks “Automatically receive flow picking task”.

As shown in Figure 9, by selecting the option of “Automatically receive flow picking task” in the corresponding interface of the inventory unloading system 900 of one embodiment of the present invention, the system automatically sends the flow picking task to the sorting operator. distribute.

Here, the system distinguishes the types of picking tasks that the sorting worker can receive, depending on the sorting worker's set authority.

Step 2: Determine if the sorter is receiving the task for the first time.

(1) When receiving a task for the first time, according to the ordering result of the picking task density of all idle aisles (no sorting workers during picking), one aisle with the highest density is selected as the picking aisle, and according to the storage location code Select one storage location with picking tasks in order from smallest to largest.

(2) Otherwise, according to the sorting worker's previous picking storage location, the storage location order and aisle order (first determine whether there is a picking waiting task in the storage location behind the previous picking storage location of the current aisle, and if not, , select the storage location where the next picking task is located (the next idle aisle is determined according to the aisle code order).

Step 3: WMS (Warehouse Management System) server background calculation: Picking task (i.e., multiple orders for the same SKU in the same storage location) by merging the location information of all items waiting to be picked in the selected storage location according to the SKU dimension. is positioned by and merged into one picking task specification). For all picking tasks, the strategy for determining the receiving order of picking tasks is as follows:

(1) The picking task with the largest number of items is received first.

(2) If the number of items is the same, the picking task with the earlier order lot time will receive priority.

(3) If the lot times are the same, the picking task with the earlier order reception time will receive priority.

(4) The sorting worker succeeds in receiving the picking task at the storage location and enters the next shipping process.

Step 4: The handheld terminal of the sorting worker is moved to the container page to which the picking task is bound, and the system starts the scanning sequence (Container A is a container close to the handle of the picking device, Container B is a container far from the handle of the picking device) Presented, the sorting operator scans the two container codes in turn, and after the check of the container's usable status passes, the system records the correspondence between the container location and the container code. The system defaults to Container A corresponding to multi-item orders and Container B corresponding to single-item orders.

As shown in Figure 10, the interface of the picking binding container 1000 of the exemplary embodiment of the present invention includes "Container A", "Container B", the number of "Container A" to be unloaded (waiting for input), and " It includes, but is not limited to, the number of items to be unloaded in inventory of “Container B” (waiting for input), the handle of the picking device (1002), the “Confirm” option, and the “Cancel” option.

Here, each time an inventory unloading operation is performed, container A and container B must be scanned in order. When binding containers, the scanning order of container A and container B is reversed, and if the opposite scanning order is maintained during the picking process, the task types of container A and container B recorded by the system will not match the actual items. For example, if a container code that is far from the handle of the picking device is scanned in the input frame of container A, the system will determine that the container code that is far from the handle of the picking device (1002) corresponds to a multi-item order, but that the actual item placed is a single item. The system records that the container close to the handle of the picking device corresponds to a single-item order, but records the actually placed item as an item from a multi-item order.

In one embodiment of the present invention, when there is a discrepancy between the inventory recorded in the system and the actual inventory, if it is determined that the cause of the discrepancy is excess inventory, the container processes excess inventory when introducing, distributing, or rechecking (thereafter, an inventory return operation) ), and if it is determined that the cause of the discrepancy is inventory shortage, a discrepancy record is created and a picking task is added.

Step 5: If container number binding is successful, the items waiting to be unloaded from inventory, the storage location number, and the number of items to be unloaded from inventory are displayed on the interface of the sorting worker's portable terminal.

The sorting worker scans the barcode of the product, checks whether it matches the product displayed on the interface, checks the actual number of inventory in the storage location, determines that the actual number of inventory is greater than the number to be unloaded, and determines the actual number of inventory to be unloaded. Enter .

As shown in Figure 11, the system checks whether the actual number of inventory unloaded matches the number to be unloaded, and the corresponding interface of the flow selection inventory unloading 1102 in one embodiment of the present invention is "Item name: xxxxxx" , “Storage location code: 1ac001”, “SKU code: 100100101”, “Number to be unloaded in inventory: 16”, “Actual number to be unloaded in inventory”, “Confirm” option, and “Container full” option. It is not limited.

(1) If the inspection matches, the portable terminal presents the number of inventory to be unloaded in the two containers to the sorting worker, and the sorting worker takes out the items from the storage location, places them in the corresponding container, scans the storage location code, and Submit storage location inventory unloading results.

As shown in Figure 12, the corresponding interface of the flow sorting inventory unloading 1202 in one embodiment of the present invention is "item name: xxxxxx", "storage location code: 1ac001", "SKU code: 100100101", "stock Number to be unloaded: 16”, “Actual number of inventory to be unloaded: 16”, Number of inventory to be unloaded in “Container A” (awaiting input), Number of inventory to be unloaded in “Container B” (waiting for input), “ Confirm” option and “Container full” option.

(2) If the inspection does not match, it moves to the picking difference page. Sorting workers enter the number of stock shortages or damaged items depending on the actual situation.

As shown in Figure 13, the corresponding interface of the flow sorting picking difference report 1302 in one embodiment of the present invention is "item name: xxxxxx", "storage location code: 1ac001", "SKU code: 100100101", " Includes “Number of items to be unloaded in stock: 16”, “Actual number of items unloaded in stock”, “Number of items out of stock: 2”, “Number of damaged items” (awaiting input), “Confirm” option, and “Container full” option, It is not limited to this.

The sorter selects the “Confirm” option to confirm submission of the item difference count. The WMS system background matches the item difference with the order type (including single item and multiple item), and the matching rules are as follows:

(a) Determine whether there is an order for the product in the current order picking backlog pool, and if it is determined that there is only one order type corresponding to the differential product, match the product to the order type. If it is confirmed that there are multiple order types corresponding to the difference product, the next step is entered.

(b) Calculate each item's picking backlog share in the current order production pool: Taking a single-item order as an example, the calculation method is as follows: single-item product backlog share = picking backlog/task distribution dispatch of the corresponding item in a single-item order The demand for all packaged single-item orders is the number of orders for that product.

(c) Compare the backlog share of single-item items and the backlog share of multi-item items, and if it is determined that the difference count < backlog share is the type of backlog with a small backlog, the goods are directly matched to the order type with a small backlog share, and the difference number is the backlog share. If the backlog of this small type is greater than or equal to the backlog, products with a difference number equal to the backlog are matched to the order type with a small backlog share, and products with a difference number exceeding the backlog are matched to a type with a large backlog share.

(d) After the difference number is matched with the order type, warehouse relocation and additional picking tasks are created according to the selected type. After creating an additional picking task, the sorting worker's portable terminal is moved to the page of flow sorting inventory unloading 1102, and the actual inventory unloading number of the two containers is recalculated according to the difference number.

(e) The sorting worker removes items from the storage location and places them in the corresponding container according to the actual inventory unloading number, scans the storage location code, and submits the inventory unloading results.

Step 6: The sorting worker automatically receives the picking task of the remaining items in the current storage location or receives the picking task of the next nearby storage location.

As shown in Figure 14, the corresponding interface of the flow sorting inventory unloading 1402 in one embodiment of the present invention is "item name: xxxxxx", "storage location code: 1ac001", "SKU code: 100100101", "stock Number to be unloaded: 16”, “Actual inventory to be unloaded”, Number of inventory to be unloaded in “Container A”, Number of inventory to be unloaded in “Container B”, “Confirm” option and “Container full” option. Includes, but is not limited to. Here, the number of items to be unloaded in “Container A” is 8, and the number of items to be unloaded in “Container B” is 6.

Step 7: Repeat steps 5 and 6 until one of the picking containers is full with items, click the Fill Containers button, select one or two containers to be filled, and after the containers are successfully filled You must rebind the empty containers after the picking task and input.

Step 8: After the container is full, an input task is sent to WCS (Warehouse Control System, a further management control system interposed between the WMS system and the PLC system), and the sorting operator puts the full container in. , WCS transports containers to the introduction/distribution desk or re-confirmation desk depending on the task type corresponding to the container.
