For the target articles, the number of the containers filled with the containers can be obtained through the number information and the container specified storage number, and some scattered target articles which cannot be fully stored according to the container specified storage number can be obtained, and the number of the scattered target articles is the zero-surplus warehouse-out number.
S104, selecting different picking strategies according to a preset ratio range according to the zero-surplus warehouse quantity and the container specified containing quantity.
In this step, a specific embodiment is provided for selecting different picking strategies according to a preset ratio range according to the zero-redundancy warehouse quantity and the container specified holding quantity. And after the target articles with the zero-redundancy warehouse-out quantity are superfluous, determining different picking strategies according to the ratio range of the zero-redundancy warehouse-out quantity and the container specified containing quantity.
S105, picking the target object through preset picking equipment according to different picking strategies.
In the steps a specific step of effecting picking of said target item by pre-setting picking equipment according to different said picking strategies is provided. The picking includes the picking of the full container of the target object and the picking of the target object with the zero-surplus warehouse quantity, and for the case of the full container, the full container can be directly used for entering the next logistics link.
In this embodiment, a specific implementation of a method for sorting a logistics is provided. The following describes the present embodiment in detail through a logistics scene, and it should be noted that, the logistics scene in the present embodiment is only for better describing the present embodiment, and is not a specific limitation of 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 containers carrying the target articles with the specified container holding quantity according to instructions so as to achieve the target article quantity required in the warehouse-out information. Before the conveying equipment conveys the full containers with the containers in the specified quantity to the mechanical arm, the mechanical arm picks and grabs the target objects on the full containers, and first, the conveying equipment receives the ex-warehouse information of the target objects, wherein the ex-warehouse information comprises the class information and the quantity information of the target objects. The background system firstly receives an order from the front end of sales, and then issues an instruction for picking the to-be-picked item according to the condition of the order, wherein the instruction has 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 be provided with the category information for identifying the category of the target item and the quantity information for subsequent selection of different picking strategies. The container specified storage quantity of the target object is called from a preset data source according to the class information, and the background does not know the container specified storage quantity at the data level, so that the call of the data is required, and the data source can be the same as the ex-warehouse information or preset information stored locally in a background system. And then, calculating the zero-surplus warehouse quantity of the target objects according to the quantity information and the container specified storage quantity, wherein when the container specified storage quantity is integral multiple of the quantity of the target objects, the conveying equipment can directly convey the container full of the container to the next logistics link node, and further sorting is needed for the zero-surplus warehouse quantity. Selecting different picking strategies according to the preset ratio range according to the zero-surplus warehouse-out quantity and the container specified containing quantity, and finally realizing picking of the target object through preset picking equipment according to the different picking strategies. And picking the target articles with the zero surplus warehouse quantity through the preset picking equipment, and if the container is the target article with the full container, directly conveying the full container to a 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 flow chart 200 of a method for sorting logistics according to another embodiment of the present application. As shown in fig. 2, in one embodiment, the selecting different picking strategies according to the preset ratio range according to the number of the spare warehouse and the specified container holding number includes:
s201, dividing the zero-redundancy ex-warehouse quantity by the container specified storage quantity to obtain a ratio range.
A specific calculation step of the ratio range is provided in this step. And calculating the number of the zero-redundancy warehouse-out containers and the specified container holding number in a container-full state, and determining the bearing state of the number of the zero-redundancy warehouse-out containers on the containers so as to determine different subsequent picking modes.
S202, judging according to a preset threshold according to the ratio range, and selecting a positive picking strategy when the ratio range is smaller than the preset threshold, wherein the positive picking strategy is that after the target articles with zero surplus warehouse quantity are picked onto an empty first target container, other articles to be picked are picked onto the first target container, so that at least two types of articles to be picked are picked on the first target container, and the at least two types of articles to be picked comprise the target articles.
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 a preset threshold value, the zero-redundancy warehouse quantity is too small in one container, if the next logistics node is directly entered, the carrying mode of the container is obviously low in efficiency, and therefore the positive picking strategy is to pick the target articles with the zero-redundancy warehouse quantity on the first empty target container. In addition to the target items, other items to be picked may be placed on the first target container. The first target container may also be understood as a series of stock storage containers such as trays, totes, bins, etc. The first empty target container can also be obtained by dispatching an AGV trolley 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, it is stated that for one container, if only the target items are 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, and for the background of the system, since each of the items to be picked corresponds to one code in the system, and placing a plurality of the items to be picked on one container is called a mixed code, i.e. a positive picking strategy, the zero-surplus warehouse quantity of the target items is picked onto the first target container which is empty, and the first target container has at least two items to be picked thereon, the at least two items to be picked including the target items.
In an embodiment, the selecting different picking strategies according to the preset ratio range according to the number of the spare warehouse and the specified containing number of the containers further comprises:
and when the ratio range is greater than a preset threshold value, selecting an anti-picking strategy, wherein the anti-picking strategy is used for picking the target objects from a second target container containing the container with the specified containing quantity, so that the second target container contains the target objects with the zero-surplus warehouse quantity.
In this embodiment a specific implementation is provided when the ratio range is greater than a predetermined threshold. In this embodiment, when the ratio range is greater than the predetermined threshold, it is indicated that the target articles in the container are already near saturation, and if other articles to be picked are added for mixing, although this is possible, the overall efficiency may be reduced, so that only the target articles may be placed on the second target container, and in addition, since most of the second target containers are the target articles, the second target containers are picked back in a state that the target articles are full, i.e. the redundant target articles are removed from the full containers. The second target container with the container regulated to hold the number can be obtained by scheduling the AGV at the goods shelf of the target object.
FIG. 3 is a flow chart 300 of a method for sorting logistics according to another embodiment of the present application. In one embodiment, as shown in fig. 3, after the selecting the positive pick policy step when the ratio range is less than a predetermined threshold, the method further includes:
s301, integrating the quantity of the zero-redundancy warehouse and the quantity of other preset items to be picked to obtain picking sets of different items, wherein the picking sets comprise category information and quantity information of the different items to be picked.
A specific implementation step is provided in this step for the case of mixing codes. The system background is required to compile the zero-redundancy warehouse-out quantity and other objects to be picked, uniformly place the zero-redundancy warehouse-out quantity and other objects to be picked in the picking collection to form a class, and is used for forming instructions for the mechanical arm.
The picking of the target object by presetting picking equipment according to different picking strategies comprises the following steps:
s302, picking the target object and other objects to be picked to the first target container through the picking equipment according to the picking collection.
In this step, a specific step of picking the target item and other items to be picked by the preset picking device according to the picking set forming instruction is provided.
In this embodiment, a specific implementation of how the system background forms a collection for the target item and other items to be picked is provided. Each item to be picked has a unique code, and the collection has the item information and the quantity information of all the items to be picked that need to be mixed. Based on this set, instructions may be issued to control the preset picking devices to pick.
FIG. 4 is a flow chart 400 of a method for sorting logistics according to another embodiment of the present application. In one embodiment, as shown in fig. 4, before the step of selecting different picking strategies according to the preset ratio range according to the number of the spare warehouse and the specified container holding number, the method further includes:
s401, receiving ex-warehouse item information list information, wherein the ex-warehouse item information list information comprises item information and quantity information of items to be picked, and the items to be picked comprise the target items.
A specific step of receiving inventory information of the item to be picked is provided in this step, which is based on all of the items to be picked, not for the target item.
S402, adjusting the ratio range according to the warehouse-out article information list and a preset adjustment mode.
In this step a specific embodiment for adjusting the ratio range is provided. Because the types of the objects to be picked are possibly different according to the inventory information of the objects to be picked, the corresponding volumes and the arrangement modes are also different, and the ratio range is required to be adjusted to achieve the maximization of the picking efficiency.
In this embodiment, by looking up the information list of the articles to be picked, according to the specific conditions of all the articles to be picked, the user may actively or in a pre-configured manner adjust the threshold value of the ratio range, so as to achieve the purpose of improving efficiency to the greatest extent.
In one embodiment, the present application provides a logistic picking system comprising: a backend system and picking device, a plurality of containers;
the background system is used for receiving the ex-warehouse information of the target article, wherein the ex-warehouse information comprises the class information and the quantity information of the target article; invoking the container specified containing quantity of the target object from a preset data source according to the class information; calculating the number of zero-redundancy warehouse-out of the target object according to the number information and the container specified storage number; selecting different picking strategies according to a preset ratio range according to the zero-redundancy warehouse-out quantity and the container specified containing quantity; and according to different picking strategies, picking the target articles to the containers by presetting the picking equipment.
In an embodiment, the picking device comprises a robotic arm and/or an AGV trolley.
Taking three kinds of to-be-sorted articles, namely a mobile phone, a notebook computer and an earphone as examples, the whole flow of the application is further described in detail, and it should be pointed out that the example is only for better describing the technical scheme of the application, and is not a specific limitation of the application.
Firstly, the picking device comprises a mechanical arm and/or an AGV trolley, wherein conveying devices of containers are arranged around the mechanical arm, the AGV trolley can also complete tasks of the mechanical arm, the flexibility is higher, the AGV trolley can automatically find the conveying devices, and no matter what way is adopted, the containers with reasonable quantity of objects to be picked are conveyed to a next logistics node through the conveying devices or the AGV trolley.
Of course, the above scenario occurs in a warehouse link, where a large number of non-picked items are stored in the warehouse, where the non-picked items are placed on containers, where the containers may be transported by the transport device and the AGV cart, where the containers may contain a specified number of items, where the number of items is affected by the carrying capacity of the containers, and where the requirements of various elements of the rationality of placement all have a maximum number of item carriers, where the maximum number of item carriers is often placed on the containers from the pallet to the container, where the items on such containers are items of the same category, where the items actually needed to be transported to the next logistics node are often mixed together, or where the items are still one item, where the maximum number of item carriers is not needed, but where in the prior art, the above mentioned tasks are all implemented by personnel, so that the efficiency is extremely low.
How to complete picking of intermixed different items? Or how are the number of items on the container required to meet the requirements? The application provides a logistics picking method for reasonably realizing the object picking process by adopting a mechanical arm or an AGV trolley with loading and unloading capabilities.
The application will be better described with respect to one of the plurality of items to be picked, i.e. the target item, for example with a cell phone, in order to simplify the calculation model.
And receiving the ex-warehouse information of the target article, wherein the ex-warehouse information comprises the class information and the quantity information of the target article.
The background system receives the ex-warehouse information of the mobile phone, wherein the ex-warehouse information comprises the class information, namely, the target object is determined to be the mobile phone, and the mobile phone is enabled to have a unique corresponding code. The quantity information is the specific quantity of the mobile phone in the ex-warehouse information.
The background system will continuously receive the ex-warehouse information, which is order dependent. For example, the number information of the mobile phone is 32 stations to be picked.
And calling the container specified containing quantity of the target object from a preset data source according to the class information.
When the background system acquires the category information, the container specified holding quantity can be called from the data source. It should be noted that the data source may be the ex-warehouse information, or may be obtained from other data sources, for example, different target objects may be stored in the target server according to different containers.
And calculating the zero-redundancy warehouse quantity of the target object according to the quantity information and the container specified storage quantity.
As described above, the containers conveyed by the conveying apparatus each hold the target articles in the prescribed holding amounts, that is, the cell phones. However, the quantity information may not necessarily be obtained from a full container, i.e. a container with the specified container quantity, for example, 10 containers, and then three containers are the full container, but there are 2 mobile phones remaining, and the remaining 2 mobile phones are called the zero-redundancy warehouse quantity.
And selecting different picking strategies according to a preset ratio range according to the zero-redundancy warehouse-out quantity and the container specified containing quantity.
The ratio of the number of 2 mobile phones to the number of containers specified to be contained, i.e. 2 divided by 10, is 0.2. Setting a ratio range, when the ratio range is 0 to 50%, the mobile phone is indicated that 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 picking strategies are adopted for different container utilization rates.
The concept of three picking strategies, namely positive picking, negative picking and whole picking, is introduced, wherein the positive picking is to place the mobile phones with zero quantity left in a warehouse on an empty container, namely two mobile phones are placed on the empty container, and then the mobile phones are combined with the previous three full containers, namely 32 mobile phones in total, so that the quantity requirement in the quantity information is completed.
The number information can be obtained by reversely sorting, for example, a full container is provided with 10 mobile phones, the 8 mobile phones can be taken down, so that two mobile phones are arranged on the container, the container with the remaining two mobile phones is provided with three full containers, and the total number of the mobile phones is 32.
The whole tray is actually a full container, because the number of the spare containers is zero at some time, that is, for example, the number information is 30, and three full containers can complete the number information.
Obviously, 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 from greater than 50%.
However, when the ratio is in the range of 0 to 50%, the container has a large free space after the positive picking, which may reduce the use efficiency of the container, so we introduce the concept of mixing codes, that is, putting the number of the spare containers of other objects to be picked on the same container, so as to improve the use efficiency of the container.
If the number of the zero-redundancy ex-warehouse is zero, the picking can be completed directly through the whole pallet.
And according to different picking strategies, picking the target object through preset picking equipment.
And finally, finishing the picking of the target object by the preset picking equipment according to different picking strategies.
The preset picking equipment comprises a mechanical arm, a first conveying equipment and a second conveying equipment, wherein the first conveying equipment is used for conveying containers in a full container state to a front or next logistics node of a working position of the mechanical arm, and the second conveying equipment is used for conveying empty containers to the front or next logistics node of the working position of the mechanical arm. Wherein, the arm, first conveying equipment and second conveying equipment can all replace through the AGV dolly.
When the picking is carried out, before the second conveying equipment sends the empty container to the working position of the mechanical arm, before the first conveying equipment sends the container in the state of being full to the working position of the mechanical arm, for the case of the mobile phone, the mechanical arm takes out 2 mobile phones from 10 mobile phones in the state of being full of the first conveying equipment and places the two mobile phones on the empty container of the second conveying equipment. For example, the number of the notebook computers and the headphones in the article to be sorted is zero, the number of the notebook computers is 3, the number of the headphones is 2, and 3 notebook computers and 2 headphones can be placed on the container in a mixed code mode under the condition that the container can be loaded. The specific conditions that can be carried are all available to those skilled in the art and will not be described in detail herein. That is, 2 mobile phones, 3 notebook computers, 2 earphones and three articles to be sorted are all provided with unique codes, namely the article information, on the empty container of the second conveying device. The background system will place three codes in the order when sending a picking order to the preset picking device. The container with the items to be picked placed is then transported by the second transport means to the next logistics node.
If the sorting strategy is the anti-sorting strategy, before the first conveying equipment conveys the full container to the working position of the mechanical arm, for example, the number information of the mobile phones is 18, the number of the zero-redundancy warehouse is 8, 2 containers are required to be removed from the full container, then the first conveying equipment conveys the container with the 8 mobile phones to the next logistics node, and when the full container is added, the two containers are added to be 18.
If the number information is a whole holder, for example, 20 mobile phones, the first conveying equipment is only required to directly convey two full containers to the next logistics node.
