Detailed Description

Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

In the warehouse environment with both manual picking and machine picking, goods on the same manifest are scattered in the manual picking area and the machine picking area respectively, and different picking modes result in that all picking cannot be completed by the same person.

Generally, a sorting container in a machine sorting area and a sorting container in a manual sorting area are subjected to confluence operation in a partition sorting mode, and sorting is finally completed. For the district goods picking, the goods in one storage area are picked and placed into one container, and the goods in different storage areas cannot be picked and placed into the same container, so that the use number of the containers is increased. In addition, the labor cost of the confluence post is increased. Thereby increasing warehouse production costs.

In order to solve the technical problem that goods in different storage areas cannot be picked and placed in the same container and the using number of the containers is increased, the following technical scheme in the embodiment of the invention can be adopted.

Referring to fig. 1, fig. 1 is a schematic diagram of warehouse area division according to an embodiment of the present invention, which includes storage areas a to L and a relay interface area. The relay interface section includes 6 interface points. Taking bin I as an example, the exemplary depicted bin I includes 12 bin shelves on which goods may be placed.

Referring to fig. 2, fig. 2 is a schematic diagram of a main flow of a picking method according to an embodiment of the present invention, picking a picking container loaded with a relay picking order sheet at an intersection, and picking the goods in the next relay picking order sheet to the picking container. The execution subject of each step in fig. 2 may be a background server. As shown in fig. 2, the method specifically includes the following steps:

s201, dividing the picking task list into a plurality of relay picking task lists according to the storage area, and determining the picking sequence of the relay picking task lists.

A quantity of orders to be picked is selected, and a picking order may be generated taking into account the volume of the picking containers and the volume of items in the orders to be picked. As an example, if the volume of the picking receptacle is 1 cubic meter, the volume of the goods in the to-be-picked manifest 1 is 0.4 cubic meter, the volume of the goods in the to-be-picked manifest 2 is 0.3 cubic meter, and the volume of the goods in the to-be-picked manifest 3 is 0.5 cubic meter, then the to-be-picked manifest 1 and the to-be-picked manifest 3 may be selected to generate a picking order sheet.

The picking task list comprises a plurality of goods to be picked, and the picking task list can be split into a plurality of relay picking task lists according to the storage areas where the goods are stored. And respectively enabling goods to be picked in the picking task list PK001 to belong to 3 storage areas, and splitting the picking task list PK001 into 3 relay picking task lists. The identifications of the relay picking task list are respectively as follows: PK001-1, PK001-2 and PK 001-3. And selecting the task sheet PK001 as a relay task sheet group number.

Due to the fact that a plurality of relay picking task lists exist, the picking sequence of the relay picking task lists can be determined according to the storage area. As an example, the picking order is split into 3 baton picking order by storage area. The goods in the relay picking order sheet 1 are stored in the storage area 1, the goods in the relay picking order sheet 2 are stored in the storage area 2, and the goods in the relay picking order sheet 3 are stored in the storage area 3. The order of the storage area 1, the storage area 2 and the storage area 3 is used as the picking order of the 3 relay picking tasks. The specific order of picking is as follows: a relay picking task list 1, a relay picking task list 2 and a relay picking task list 3.

S202, after a relay picking task list is finished, according to the position identification and the storage area of one relay picking task list and the storage area of the next relay picking task list, the junction is searched in a preset junction address library.

The goods picker receives a relay goods picking task sheet, places all goods under the relay goods picking task sheet in a picking container, and marks the relay goods picking task sheet as a goods picking completion state after goods picking is completed.

After one relay picking task sheet is finished, the database is inquired according to the relay task sheet group number of the relay picking task sheet to obtain the next relay picking task sheet. As an example, PK001 is the relay order group number, and the identification and picking order of the relay picking order are: PK001-1, PK001-2 and PK 001-3. After the relay picking task sheet PK001-1 is finished, the database is inquired according to the PK001, and the next relay picking task sheet is acquired as PK 001-2.

In the embodiment of the invention, the goods in the relay picking order sheets can be placed in the same picking container, and the picking container which already comprises the goods in one relay picking order sheet needs to be placed at the junction so as to place the goods in the next relay picking order sheet in the picking container.

Then, the intersection can be searched in the preset intersection address base according to the position identifier of one relay picking task list, the storage area and the storage area of the next relay picking task list. The preset access point address library stores the corresponding relation among the position identification, the storage area and the access point.

In one embodiment of the present invention, the bank of contact addresses may be set up in the following manner.

Referring to fig. 3, fig. 3 is a schematic flow chart of setting a contact point address library according to an embodiment of the present invention, which specifically includes:

s301, dividing the handover rule in the handover rule configuration file into different levels of identifiers, wherein the handover rule comprises a position identifier, a storage area, a relay storage area and a handover point of the relay picking task list.

And identifying the intersection points among different warehouses, different merchants, different bill types and different front and back storage areas, and dividing the intersection points into a cross-connection rule according to a fixed sequence. As an example: the handover rules for warehouse number w1, merchant s1, document type r1, storage area z1, relay storage area z2 with j1 are as follows: w1-s1-r1-z1-z2-j 1. Where the warehouse number, merchant, and document type are referred to as location identifiers.

For each intersection point, a corresponding intersection rule is identified. And writing the handover rule into a handover rule configuration file.

And encrypting the rule configuration file into a ciphertext through an asymmetric encryption algorithm and storing the ciphertext. The ciphertext is then decrypted by a corresponding asymmetric decryption algorithm.

The transfer rule comprises a position identifier, a storage area, a relay storage area and a transfer point of the relay picking task list. The handover rules may be divided into different levels of identification. As an example, the following designations are respectively, from high level to low level: w1, s1, r1, z1, z2, j 1.

S302, inserting the identifiers of different levels into the multi-branch tree as tree nodes according to the sequence from high level to low level, wherein the leaf nodes of the multi-branch tree are cross points.

First, there is a root node "-" of the multi-way tree, and the identifiers are inserted into the multi-way tree as tree nodes in the order from high level to low level. As an example, the identifications from high level to low level are respectively: w1, s1, r1, z1, z2, j 1. Then, the following tree nodes are inserted into the multi-branch tree, the root node "-" of the multi-branch tree, then w1 is used as a tree node, s1 is used as a tree node under w1, r1 is used as a tree node under s1, z1 is used as a tree node under r1, z2 is used as a tree node under z1, and j1 is used as a leaf node of z 2.

When inserting the identifier, if there is already the same node under the same root node, then it is not necessary to re-insert, and the loop is repeated, so as to generate the multi-way tree shown in fig. 4.

Referring to fig. 4, fig. 4 is a schematic diagram of a multi-way tree according to an embodiment of the present invention. In fig. 4, the root node of the multi-branch tree belongs to 3 tree nodes, and each tree node belongs to a plurality of nodes. The left branch is defined by the following handover rule: w1-s1-r1-z1-z2-j 1.

S303, taking the multi-branch tree as a preset junction point address base.

And taking the multi-branch tree established based on the handover rule as a preset handover point address base. It will be appreciated that the predetermined bank of contact addresses may be established in other ways. Such as: and establishing a table of corresponding relations among the intersection points, the position marks and the storage areas.

In one embodiment of the invention, the junction point is searched in the preset junction point address base according to the position identifier of one relay picking task list, the storage area and the storage area of the next relay picking task list. For example, the junction may be obtained by querying a predetermined junction address bank based on the location identifier, the current storage area, and the storage area of the next relay picking order.

S203, receiving the information that the picking container is at the junction point, and loading the picking container with goods in a relay picking task list.

To alert the picker of the accurate placement of the picking containers, a prompt message including the point of delivery may be sent to the picker. As an example, after determining the point of intersection, a prompt including the point of intersection is sent to the picker's mobile terminal.

And the order picker places the picking containers including the goods in the relay picking task list at the cross point according to the prompt information. The picker scans the number bar code of the interface point, identifying the interface point to confirm that a picking container has been placed at the interface point.

Then the junction sends a message to the back-end server that the picking container is already at the junction. The background server receives a message that the picking container is already at the intersection. Wherein, the picking container is loaded with goods in a relay picking task list.

S204, receiving the information that the picking container is picked up at the cross-point, and searching the cross-point again in the preset cross-point address base.

The picker may pick the picking container at the junction to pick the next item in the relayed picking order to the picking container. Then, if the database is queried according to the relay task single group number and the next relay picking task list can be obtained, S201 to S204 can be executed again until the next relay picking task list is obtained unsuccessfully.

In one embodiment of the invention, after a picking container of goods in one relay picking order is placed at the junction, a prompt message including the identification of the junction and the picking container may be sent to a picker of another relay picking order. To prompt the picker that the picking container is placed at the delivery point and to request timely pick.

The junction sends a message to the background server that the picking container has been picked at the junction. The background server receives the information that the picking container is picked up at the junction, and the background server can search the junction again in the preset junction address base.

In the above embodiment, after the picking containers have been loaded with the goods in one relay picking order, the picking containers may be placed at the junction point, so that the picking containers are loaded with the goods in another relay picking order, and the goods in different storage areas can be picked and placed in the same picking container, thereby improving the utilization rate of the picking containers and reducing the number of the picking containers used. The labor cost of the confluence post is reduced, the production efficiency is not reduced, and the production cost of the warehouse can be reduced.

In one embodiment of the invention, the junction may need to be monitored in order to ensure that picking containers are accurately delivered at the junction in a timely manner.

Referring to fig. 5, fig. 5 is a schematic flow chart of monitoring a junction according to an embodiment of the present invention, which specifically includes the following steps:

s501, determining that the cross-connection point is consistent with the assigned cross-connection point, and increasing the quantity of the relay picking tasks of the cross-connection point by one.

After searching for the delivery point in the predetermined delivery point address library, the picker responsible for picking may receive a prompt including the delivery point. Therefore, the picking personnel can place the picking containers loaded with the relay picking task single goods in the prompted delivery point according to the prompt information.

The picker needs to determine whether the pick container is at an intersection consistent with the intersection designated in the prompt. As an example, the order picker scans the identifier of the delivery point where the picking container is located, and if the identifier of the delivery point is consistent with the designated delivery point, the delivery point is bound with the picking container, thereby indicating that the picking container is placed at the delivery point; if the mark of the located delivery point is different from the designated delivery point, the situation that the picking personnel places the picking container incorrectly is indicated, and the picking container needs to be placed again according to the prompt information.

And determining that the cross point of the picking container is consistent with the assigned cross point, and recording the single quantity of the relay picking tasks of the cross point by the background server by one. The purpose of recording the number of the relay picking task lists in the delivery point is to monitor each relay picking task list in real time and prompt a picker to pick up picking containers at the delivery point in time.

It will be appreciated that the number of relay picking order sheets at the junction is the same as the number of picking receptacles, with one picking receptacle representing one relay picking order sheet.

S502, after the picking containers are picked up at the junction, the number of the relay picking task lists of the junction is reduced by one.

After the picking containers loaded with the goods in the relay picking order sheet are placed at the delivery point, prompt information can be sent to the picker, and the prompt information can comprise the identification of the delivery point and the picking containers so as to prompt the picker to pick the picking containers with the identification at the delivery point. As one example, the picker scans the identification of the picking container at the point of intersection to pick up the picking container.

After the picking member receives the picking container, the background server records the relay picking task list number of the delivery point and reduces one.

The quantity of the relay picking task lists of the cross points can be monitored in real time at each cross point, so that the picking progress of the relay picking task lists can be obtained on one hand; in another aspect, the backlog of the cross-over point may be known to adjust the number of pickers. As one example, a prompt message may be sent to the picker, including the number of pick order delivery points.
