Fig. 1 is a schematic diagram of a process 100 for sorting a material flow according to an embodiment of the present invention. As shown in fig. 1, in one embodiment, the present application further provides a method of sorting a stream, the method comprising:

s101, receiving warehouse-out information of a target object, wherein the warehouse-out information comprises category information and quantity information of the target object

In this step, a specific embodiment of receiving the ex-warehouse information of the target item is provided. One of the plurality of items to be picked, i.e., the target item, is established in this step. The item information may be used to indicate the item type of the target item, i.e., a specific type of merchandise. The item information can at least distinguish different commodity types, the item information can be distinguished and identified by the codes of the commodities, and the codes are unique in the system. The quantity information refers to the specific quantity to be sorted.

And S102, calling the specified accommodating quantity of the containers of the target articles from a preset data source according to the article type information.

In this step, a specific step of calling the specified holding quantity of the container of the target object from a preset data source through the item type information is provided. The item information also stores the specified quantity of different items in the container in the data source, namely the specified quantity of different items in the container.

And S103, calculating the zero-surplus warehouse-out quantity of the target articles according to the quantity information and the specified accommodating quantity of the containers.

In this step, a specific step of calculating the zero-out warehouse quantity of the target object according to the quantity information and the specified containing quantity of the container is provided. For the target articles, the number of the containers of the full container can be obtained through the quantity information and the specified storage quantity of the containers, and some scattered target articles which cannot be completely stored according to the specified storage quantity of the containers exist, and the quantity of the scattered target articles is the zero surplus warehouse-out quantity.

And S104, selecting different picking strategies according to the zero surplus warehouse-out quantity and the specified accommodating quantity of the containers and a preset ratio range.

In this step, a specific embodiment is provided for selecting different picking strategies according to a preset ratio range according to the zero surplus warehouse quantity and the specified containing quantity of the containers. When the target item with the zero surplus warehouse quantity is surplus, different picking strategies are determined according to the ratio range of the zero surplus warehouse quantity and the specified containing quantity of the containers.

And S105, picking the target item through preset picking equipment according to different picking strategies.

The specific steps of picking the target item through the pre-positioned picking device according to the different picking strategies are provided in the step. The picking includes picking the target item in a full container, and picking the target item with the zero remaining warehouse quantity, and for the full container, the full container can be directly entered into the next logistics link.

In this example, a specific embodiment of a method of sorting a stream is provided. The present embodiment is described in detail below with reference to a logistics scenario, and it should be noted that the logistics scenario in the present embodiment is only for better describing the present embodiment, and is not a specific limitation to the protection scope. The picking equipment comprises a mechanical arm and/or an AGV trolley, conveying equipment and the like, and is used for picking the containers which are loaded with the specified container containing quantity of the target articles according to instructions so as to reach the quantity of the target articles required in the warehouse-out information. The conveying equipment conveys full containers containing the specified number of the containers to the front of the mechanical arm, the mechanical arm picks and grabs the target objects on the full containers, and first, warehouse-out information of the target objects is received, wherein the warehouse-out information comprises category information and number information of the target objects. The background system firstly receives an order of a sale front end, and then issues an instruction for picking the to-be-picked item according to the condition of the order, wherein the instruction comprises the ex-warehouse information. The ex-warehouse information is derived from relevant information of the target item in the order, wherein the ex-warehouse information should have the category information and the quantity information, the category information is used for identifying the category of the target item, and the quantity information is used for subsequent selection with different picking strategies. And calling the specified container containing quantity of the target object from a preset data source according to the item information, wherein the background does not know the specified container containing quantity from a data layer, so that the data is required to be called, and the data source can be the same data source as the ex-warehouse information or preset information locally stored in a background system. And then, calculating the zero-surplus warehouse-out quantity of the target items according to the quantity information and the specified storage quantity of the containers, wherein when the quantity of the target items is integral multiple of the specified storage quantity of the containers, the conveying equipment can directly convey the containers with full containers to a next logistics link node, and the zero-surplus warehouse-out quantity needs to be further sorted. And selecting different picking strategies according to the zero-surplus warehouse-out quantity and the specified containing quantity of the containers and a preset ratio range, and finally picking the target items through preset picking equipment according to the different picking strategies. And picking the target items with the zero surplus warehouse quantity through the preset picking equipment, and if the target items on the containers are full containers, directly conveying the full containers to the next logistics node through the conveying equipment. The embodiment provides a specific picking method for the target object through the preset picking equipment in the above manner, which is helpful for solving the technical problem of low efficiency caused by manual picking in the prior art.

Fig. 2 is a schematic diagram of a process 200 for sorting a material flow according to another embodiment of the present invention. As shown in fig. 2, in an embodiment, the selecting different picking strategies according to the zero surplus warehouse quantity and the specified container holding quantity according to the preset ratio range includes:

and S201, dividing the number of the zero surplus warehouses by the specified containing number of the containers to obtain a ratio range.

A specific calculation step for the range of ratios is provided in this step. And calculating the zero surplus warehouse-out quantity and the specified container holding quantity in the full container state, and determining the bearing state of the zero surplus warehouse-out quantity on the container so as to determine the subsequent different picking modes.

And S202, judging according to the ratio range and a preset threshold value, and selecting a positive picking strategy when the ratio range is smaller than the preset threshold value, wherein the positive picking strategy is to pick the target items with the zero surplus warehouse quantity to an empty first target container, then pick other items to be picked and place the other items to be picked on the first target container, so that at least two items to be picked are picked on the first target container, and the at least two items to be picked comprise the target items.

A specific step is provided in this step when the ratio range is less than a predetermined threshold. When the ratio range is smaller than the predetermined threshold, it indicates that the zero-over stock quantity is too small on a container, and if the container directly enters the next logistics node, it is obvious that the carrying manner of the container is inefficient, so the picking strategy is to pick the target item with the zero-over stock quantity on the empty first target container. The first target container may have other items to be picked placed thereon in addition to the target item. The first target container may also be understood as a series of inventory storage containers such as trays, totes, bins, etc. The empty first target container can also be obtained by dispatching the AGV to a warehouse.

In this embodiment, a specific implementation is provided when the ratio range is smaller than a predetermined threshold. When the ratio range is smaller than a predetermined threshold value, it means that for a container, if only the target item is placed, the utilization efficiency of the container is reduced, so that a plurality of the items to be picked should be placed on the first target container, for the background of the system, because each of the items to be picked corresponds to one code in the system, and a plurality of the items to be picked are placed on a container, which is called a mixed code, namely a positive picking strategy, the zero remaining stock quantity of the target items are picked to the first target container which is empty, and the first target container has at least two items to be picked, wherein the at least two items to be picked include the target item.

A specific implementation is provided in this embodiment when the ratio range is greater than a predetermined threshold. In this embodiment, when the ratio range is greater than the predetermined threshold, it indicates that the target item in the container is close to saturation, and if another item to be picked is added for mixing, although it may be possible, this may reduce the overall efficiency, so that only the target item may be placed on the second target container, and in addition, since most of the second target container is the target item, the second target container is anti-picked in a full container state of the target item, that is, the redundant target item is removed from the full container. The second target containers with the specified container holding quantity can be obtained by dispatching the AGV to the shelf of the target article.

Fig. 3 is a schematic diagram of a process 300 for sorting a stream in another embodiment of the present invention. As shown in fig. 3, in an embodiment, after the step of selecting a picking strategy when the ratio range is smaller than the predetermined threshold, the method further includes:

s301, according to the zero-surplus warehouse-out quantity and the preset quantity of other items to be picked, a picking set of different items is obtained through integration, wherein the picking set comprises the type information and the quantity information of the different items to be picked.

A specific implementation step is provided in this step for the case of scrambling. The system background needs to compile the number of the zero-residue warehouses and other articles to be picked, and uniformly places the warehouses and the articles to be picked in the picking set to form a class, which is used for forming instructions for the mechanical arms.

s302, picking the target item and other items to be picked to the first target container through the picking device according to the picking set.

In this step, a specific step is provided for picking said target item and said other items to be picked by said pre-picking apparatus in accordance with said picking set formation instructions.

In this embodiment, a specific implementation of how the system background aggregates the target item and the other items to be picked is provided. Each of said items to be picked having a unique code, said class information and said quantity information for all of said items to be picked in said collection being scrambled. From this set, instructions may be issued to control the pre-picking apparatus to pick.

Fig. 4 is a schematic diagram of a process 400 for sorting a stream in accordance with another embodiment of the present invention. As shown in fig. 4, in an embodiment, before the step of selecting different picking strategies according to the zero surplus bin quantity and the specified container holding quantity according to the preset ratio range, the method further includes:

s401, warehouse-out item information list information is received, wherein the warehouse-out item information list information comprises category information and quantity information of the to-be-picked items, and the to-be-picked items comprise the target items.

In this step, a specific step of receiving information list information of the items to be picked is provided, and in this step, the information list information is based on all the items to be picked and is not specific to the target item.

S402, adjusting the ratio range according to the ex-warehouse article information list in a preset adjusting mode.

One specific embodiment for adjusting the ratio range is provided in this step. Because the types of the to-be-picked items may be different according to the information list information of the ex-warehouse items, the corresponding volumes and placing modes are also different, and the ratio range is adjusted according to needs to maximize the picking efficiency.

In this embodiment, by observing the delivery item information list, according to the specific conditions of all the items to be picked, the user may actively or in a pre-configured manner adjust the threshold of the ratio range, so as to achieve the purpose of improving efficiency to the maximum extent.

Taking three specific articles to be picked, namely a mobile phone, a notebook computer and an earphone as examples, the overall process of the present application is further described in detail, and it should be noted that the present example is only for better describing the technical solution of the present application, and is not a specific limitation to the present application.

Firstly, select equipment includes arm and/or AGV dolly, wherein, be provided with the conveying equipment of container around the arm, the task of arm also can be accomplished to the AGV dolly, and the flexibility is stronger moreover, and the AGV dolly can look for by oneself conveying equipment, nevertheless no matter what kind of mode of adoption, all is through conveying equipment or AGV dolly will load reasonable quantity the container of article to be selected transports next logistics node.

Of course, the above scenario occurs in the storage link, a large amount of unsorted articles are stored in the warehouse, the unsorted articles are put on the containers, the containers can be conveyed by the conveying device and the AGV cart, the containers can contain the specified number of articles, the number of articles is influenced by the bearing capacity of the containers, and the requirement of various elements for rationality of placement can have a maximum article bearing number, the maximum article bearing number is often placed on the containers from the shelf to the containers, but the articles on the containers are the same kind of articles, the articles actually required to be conveyed to the next logistics node are often mixed together by a plurality of articles or still are one kind of articles, but the maximum article bearing number is not required in quantity, but is a single article in required quantity, in the prior art, the above work is performed by the picker, so that the efficiency is extremely low.

How to complete sorting of various articles? Or how do the number of items on the container need to be satisfactory? The method can be realized by adopting a mechanical arm or some AGV trolleys with loading and unloading capacity, and the method for sorting the logistics can reasonably realize the goods sorting process.

To simplify the computational model, the present application is better described in terms of one of the plurality of items to be picked, i.e., the target item, such as the target item on a cell phone.

Receiving the delivery information of the target object, wherein the delivery information comprises the category information and the quantity information of the target object.

And the background system receives the ex-warehouse information of the mobile phone, wherein the ex-warehouse information comprises the category information, namely the target object is determined to be the mobile phone, and the mobile phone has a unique corresponding code. The quantity information is the specific quantity of the mobile phone in the ex-warehouse information.

And the background system can continuously receive the ex-warehouse information, and the ex-warehouse information is determined by the order. For example, the quantity information of the mobile phone is that 32 mobile phones need to be picked.

And calling the specified containing quantity of the containers of the target articles from a preset data source according to the article type information.

After the background system acquires the item information, the specified holding quantity of the containers can be called from the data source. It should be noted that the data source may be the outbound information, or may be obtained from other data sources, for example, different target articles are stored in the target server corresponding to different specified container holding amounts.

And calculating the zero-surplus warehouse-out quantity of the target object according to the quantity information and the specified accommodating quantity of the containers.

As mentioned above, the containers conveyed by the conveying device are filled with the target objects, namely mobile phones, in the specified amount of the containers. However, the quantity information may not necessarily be from a full container, that is, a container containing a specified number of the containers, for example, if the specified number of the containers is 10, three containers are the full container, but there are 2 mobile phones remaining, and the 2 mobile phones remaining are referred to as the zero remainder number.

And selecting different picking strategies according to the zero surplus warehouse quantity and the specified containing quantity of the containers and a preset ratio range.

The ratio of the specified number of 2 handsets to the container, i.e. 2 divided by 10, is 0.2. And setting a ratio range, wherein when the ratio range is 0 to 50 percent, the utilization rate of the container is in a lower state under the ratio, otherwise, the utilization rate of the container is higher, and different sorting strategies are adopted for different container utilization rates.

The concept of three sorting strategies of positive sorting, negative sorting and whole picking is introduced, wherein the positive sorting is to put the mobile phones with the number of the zero surplus warehouse-out quantity on an empty container, namely to put two mobile phones on an empty container, so that the quantity requirement in the quantity information is completed by adding the three full containers before and 32 mobile phones in total.

And (3) carrying out reverse sorting, for example, one full container is provided with 10 mobile phones, the 8 mobile phones on the container can be taken down, so that two mobile phones are arranged on the container, the container with the rest two mobile phones is provided with three full containers again, and the total number of the full containers is also 32 mobile phones, so that the quantity requirement in the quantity information can be met.

The whole container is actually a container in a full container state, because sometimes the number of the zero-remaining warehouses is exactly zero, that is, for example, the number information is 30, and the number information can be completed by three full containers.

It is clear that the positive picking mode is most efficient when the ratio ranges from 0 to 50%, and the negative picking mode is most efficient when the ratio ranges more than 50%.

However, when the ratio is in the range of 0 to 50%, the containers have a large empty space after the picking mode is adopted, which may reduce the use efficiency of the containers, so we introduce the concept of mixing, that is, the zero-surplus warehouse quantity of other items to be picked is put on the same container, so as to improve the use efficiency of the containers.

If the number of the zero-remaining warehouses is zero, sorting can be finished by directly passing through the whole tray.

And finally, finishing picking of the target item according to different picking strategies through the preset picking equipment.

The preset picking equipment comprises a mechanical arm, first conveying equipment and second conveying equipment, wherein the first conveying equipment is used for conveying containers in a full container state to a position in front of a working position of the mechanical arm or a next logistics node, and the second conveying equipment is used for conveying empty containers to a position in front of a working position of the mechanical arm or a next logistics node. The mechanical arm, the first conveying equipment and the second conveying equipment can be replaced by the AGV trolley.

When the picking is being performed, the second conveying device conveys empty containers to a position before the working position of the mechanical arm, the first conveying device conveys containers in a full container state to a position before the working position of the mechanical arm, and for the case of the mobile phones, the mechanical arm takes out 2 mobile phones from 10 mobile phones with full containers on the first conveying device and places the two mobile phones on the empty containers on the second conveying device. For example, the notebook computer and the earphones in the article to be picked respectively have the number of the spare outlets, the notebook computer has 3 sets of earphones, and the 3 sets of notebook computer and the 2 sets of earphones can be placed on the container in a mixed manner under the condition that the container can bear the weight of the objects. The specific conditions that can be carried are all realized by those skilled in the art, and are not described herein again. That is to say, originally 2 cell-phones, 3 notebook computers, 2 earphones have been placed on the empty container of second conveying equipment, three waiting to pick article all have unique code because, promptly the article information. So when the background system sends a picking order to the pre-positioned picking device, three codes are put in the order. The container with the item to be picked placed thereon is then transported to the next logistics node by the second transportation means.

If the sorting strategy is the reverse sorting strategy, the first conveying equipment conveys full containers to the front of the working position of the mechanical arm, for example, the number information of the mobile phones is 18, the number of the zero-surplus warehouses is 8, 2 containers need to be taken down from the full containers, then the first conveying equipment conveys the containers with 8 mobile phones to the next logistics node, and when one full container is added, the two containers are added to be 18.

If the total support is available, for example, the quantity information is 20 mobile phones, only two full containers need to be directly conveyed to the next logistics node by the first conveying equipment.
