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.

Fig. 1 is a schematic diagram of main steps of a task dissemination method according to a first embodiment of the present invention. As shown in fig. 1, a task distribution method according to a first embodiment of the present invention mainly includes the following steps:

step S101: recommending a sowing position for the to-be-separated article according to a set recommendation strategy, and shelving the to-be-separated article to a separation wall according to the sowing position; wherein the recommended strategy comprises depositing a single kind of item to be distributed at the sowing location. After the goods are picked, the goods to be sorted obtained by picking are required to be put on a grid opening of a sorting wall. The distribution wall comprises a plurality of unit groups, each unit group comprises a plurality of grids, and each grid only stores a single kind of articles. In the shelf loading process, a sowing position is recommended for the articles to be sown according to the principle that each lattice only stores a certain type of articles. The sowing positions are the unit group number and the lattice number of the sub-sowing wall.

Step S102: and judging whether the goods on the shelves of the separate sowing wall meet the type and the quantity of the target goods specified by the task, and binding the storage equipment identifier, the task identifier of the task and the corresponding sowing position according to a set matching strategy under the condition that the goods on the shelves meet the type and the quantity of the target goods. And acquiring the type and the quantity of target articles required by each task in the task pool, and comparing the acquired type and quantity of the target articles with the type and quantity of the articles which are already put on shelves on the distribution wall.

If the goods on the shelves on the separate sowing wall meet the types and the quantity of the target goods specified by the partial tasks in the task pool, the storage equipment identifiers which are the same as the quantities meeting the tasks are respectively bound with the task identifiers of the tasks and the sowing positions of the target goods specified by the tasks according to a matching strategy. The matching strategy is used for matching tasks capable of being distributed for each storage device so as to bind the tasks and the storage devices. The fact that the items on the distribution wall are placed on the shelf meets the target item type and quantity specified by the task.

Step S103: and determining the sowing positions of the target objects of the task bound by the current storage equipment on the separate sowing wall, and throwing the objects to be separated at the corresponding sowing positions to the current storage equipment according to the quantity specified by the bound task. And determining the unit group number and the grid number of the target object on the separate-playing wall according to the type of each target object appointed in the task bound by the current storage equipment, and throwing the objects to be separated and stored in the unit group number and the grid number to the current storage equipment according to the quantity of the target objects appointed by the binding task.

In the second embodiment, steps S201 to S203 are used for shelving the items to be distributed on the distribution wall. And S204 to S207 are used for binding the storage equipment and the task. Step S208 to step S209 are for completing the item distribution. Step S210 is used to perform packing processing on the tasks completed by the split. The specific implementation is as follows.

Fig. 2 is a schematic main flow chart of a task dissemination method according to a second embodiment of the present invention. As shown in fig. 2, the task distribution method according to the second embodiment of the present invention mainly includes the following steps:

step S201: and the WMS system sends the information of the articles to be distributed to the task distribution device. Wherein, waiting to divide the broadcast article information includes: the order picking container number, basic information of the goods to be distributed and order information. After the picking is completed, the WMS (Warehouse Management System) System sends the information of the items to be sorted to the task sorting device.

Step S202: and the task distribution device recommends the cell group number and the cell number of the distribution wall for the item to be distributed according to a set recommendation strategy, and sends the cell group number and the cell number to the WMS. And after receiving the information of the articles to be distributed, the task distribution device recommends the unit group number and the lattice number of the distribution wall for the articles to be distributed according to the following recommendation strategy. In a preferred embodiment, the recommendation strategy is as follows:

(a) a single kind of objects to be distributed are stored in one cell, and different batches of objects can be mixed. Wherein, the items to be distributed with the same SKU (Stock Keeping Unit) are of one kind. The system records the batch number of each article, and if the batch numbers are different, the articles belong to different batches. For example, item a has a lot number of 123 and a lot number of 234.

(b) And in the case that the cell of the separating wall is not filled, the same item to be separated is preferentially stored in the same cell of the separating wall.

(c) And preferentially storing the objects belonging to the same task set in the cells of the same cell group of the distribution wall. The strategy enables the storage equipment to stop once, and the distribution can be completed quickly.

It is noted that the recommendation strategy needs to comprise at least (a), (b) and (c) is optional.

The specific implementation of recommending the cell group number and the lattice number of the distribution wall for the to-be-distributed item is as follows:

(1) and respectively calculating the coincidence degrees of the objects to be distributed and the objects on the shelves of the plurality of unit groups of the distribution wall. The calculation formula of the contact ratio is as follows:

coincidence degree is the kind of the goods on the shelf in the unit set, the kind of the goods to be separated and the kind of the goods on the shelf in the unit set

Equation 1 is illustrated below: assuming that the type of the overhead item in a certain unit group of the separate sowing wall is abcd, the type of the item to be separated is aberf, and the intersection of the two is ab, the contact ratio is 2/4-50%.

(2) If the unit groups with the coincidence degree larger than 0 exist, preferentially recommending the unit group with the highest coincidence degree:

if the coincidence degrees of a plurality of unit groups are the same or close to each other, the unit group far away from the inlet of the storage device is preferably recommended. Referring to fig. 5, the unit groups far away from the inlet of the storage device, that is, the unit groups with large numbers, avoid the inlet of the storage device from being blocked due to the distribution task.

Within the same set of cells, it is preferred to have compartments of the same item.

When no available grid exists in the same unit group, the grid of the unit group close to the unit group and far away from the inlet of the storage equipment is preferentially recommended.

(3) And if the contact degrees with all the unit groups are 0, calculating the association degrees among the objects to be distributed contained in the task set, and preferentially recommending the unit group where the object with the highest association degree is located. Wherein, if two items appear simultaneously in a task, the two items are related. The process of calculating the degree of association is as follows: and counting the number of tasks which are simultaneously appeared in one task by the combination of the two articles, wherein the number of the tasks is the relevance. The following examples illustrate: assuming that a task 001 and a task 002 exist in the task pool, the task 001 includes abc items, and the task 002 includes ab items, the association degree between the ab items is 2, and the association degree between the ac items is 1.

If a plurality of unit groups with the same association degree exist, the grid of the unit group far away from the inlet of the storage equipment is preferentially recommended.

Step S203: and the WMS system shelves the to-be-distributed articles to a distribution wall according to the received unit group number and the lattice number. After an RF (Radio frequency) gun of the WMS system receives the unit group number and the cell number, a rechecking sub-broadcaster puts the items to be distributed on a sub-broadcast wall according to the prompt on the RF gun. Among them, the RF gun is a hand-held device for scanning.

Step S204: the task separate-broadcasting device judges whether the shelving objects on the separate-broadcasting wall meet the type and the quantity of the target objects specified by at least one task, and if the shelving objects do not meet any task, the step S205 is executed; if the shelved item satisfies at least one task, step S206 is performed.

The step is to match the type and the number of the goods on the shelves of the separate-broadcasting wall with the type and the number of the target goods specified by the tasks, and judge how many tasks can be met by the goods on the shelves. The following examples illustrate: assuming that the articles on the shelf of the separate-broadcast wall are abcd and each article is 2, if 4 tasks include abcd and the number of the articles is 1, the number of the tasks met by the separate-broadcast wall is 2.

Step S205: after waiting for the set time, the task assigning device executes step S204. And if the shelving objects cannot meet any task, waiting for a period of time and judging again.

Step S206: the task distribution device calculates the number of tasks that the overhead articles satisfy, and performs step S207 with the number of tasks as the number of storage devices. If the number of tasks that the wall satisfies is 2, then the storing equipment quantity that needs is 2 also.

Step S207: and the task distribution device binds the storage equipment identifier, the task identifier of the task and the corresponding grid number according to a set matching strategy. According to the goods on the shelf of the separate broadcasting wall, tasks which can meet the types and the number of the target goods are selected from the task set, and the tasks are bound with the storage equipment. If a plurality of selected tasks are available, one task can be selected to be bound with the storage device according to a set matching strategy. The matching strategy here can be random selection, sequential selection according to task deadline, etc. For example, 10 tasks are concentrated in the task set, namely the task 1 to the task 10, and the articles on shelves on the separate-sowing wall can meet the task 1 and the task 2, and the task 1 or the task 2 is randomly selected to be bound with the storage device. For another example, if the deadline of the task 1 is earlier than the deadline of the task 2, the task 1 is selected to be bound with the storage device.

When the task identifier and the notch number are bound, classification can be carried out according to whether the deadline of the task is near the ending time of the secondary production, and different matching strategies are respectively set for the task near the ending time of the secondary production and the task not near the ending time of the secondary production. In the process of warehouse logistics scheduling, the scheduling is performed according to the time of 'wave times', for example, 8 wave times exist in a day, wherein 8 to 10 points are one wave time, and each wave time completes the production operation of a plurality of tasks. And judging whether the difference value between the task deadline time and the wave generation end time falls into a set time range, wherein the time range can be set by self, and if the difference value falls into the set time range, the task is the task close to the wave generation end time. For example, assume a task deadline of 9: and 40, if the wave secondary production end time is 10 points and the time range is 30min, the task is considered to be the task close to the wave secondary production end time.

In a preferred embodiment, the matching policy of the binding task identifier and the frame number is as follows:

(a) when the near wave secondary production is finished

If the single unit group and the aggregate group formed by a plurality of unit groups can meet the type and the quantity of the target articles specified by the task: the cells of a single set of cells are preferably selected to match the target item.

Under the condition that a single unit group meets the requirements, if a plurality of single unit groups can meet the types and the quantity of the target articles specified by the task: the compartments of the set of cells near the entrance of the storage device are preferably selected to match the target item. Referring to fig. 5, the set of cells close to the inlet of the storage device, i.e. the set of cells with the smaller number.

Under the condition that the set groups meet, if a plurality of set groups can meet the types and the quantity of the target objects specified by the tasks: preferably, a small number of sets comprising a single set of cells are selected for matching with the target item. For example, if the cell groups 01 and 03 satisfy one task and the cell groups 02, 03, and 04 also satisfy one task, the cell groups 01 and 03 are matched.

(b) When the non-near wave is finished

If the single unit group and the aggregate group formed by a plurality of unit groups can meet the type and the quantity of the target articles specified by the task: the cells of the collective group are preferably selected for matching with the target item.

Under the condition that the set groups meet, if a plurality of set groups can meet the types and the quantity of the target objects specified by the tasks: preferably, a large number of sets comprising a single set of cells are selected for matching with the target item. For example, if the cell groups 01, 03 satisfy one task and the cell groups 02, 03, 04 also satisfy one task, the cell groups 02, 03, 04 are matched.

Under the condition that a single unit group meets the requirements, if a plurality of single unit groups can meet the types and the quantity of the target articles specified by the task: the compartments of the set of cells remote from the access opening of the storage device are preferably selected to match the target item.

Step S208: the task distributing device determines the unit group number and the grid number of the target object of the task bound by the current storage equipment on the distributing wall, lights the electronic tag of the grid on the distributing wall and displays the distributing quantity. After the storage equipment is bound with the task, the task distribution device calculates the unit group number and the grid number of the target object in the distribution wall, wherein the target object is contained in the task bound by the current storage equipment, lights the electronic tag of the grid, and displays the quantity of the target object in the task as the distribution quantity. For example, if the number of the target articles 1 is 5, the electronic tag corresponding to the cell of the target article 1 is lit, and the numeral 5 is displayed.

Step S209: and the rechecking and separating personnel put the objects to be separated of the unit group number and the grid number into the current storage equipment according to the displayed separating quantity.
