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 order to reduce the warehousing times and/or ex-warehouse times of the goods shelf, the invention provides a warehousing scheduling method, which comprises the following steps: judging whether the warehousing quantity of the articles to be warehoused is greater than or equal to a warehousing threshold value for storing the articles on a first shelf; if yes, the articles to be warehoused are conveyed from the upper rack position to the rack storage position in a centralized mode through the first rack; and if not, dispersedly transporting the articles to be warehoused from the upper rack position to the rack storage position through the second rack. The method further comprises the following steps: judging whether the warehouse-out quantity of the articles to be warehoused is greater than or equal to a warehouse-out threshold value for storing the articles on a first shelf; if yes, the goods to be delivered are conveyed from the goods shelf storage position to the goods picking position through the first goods shelf in a centralized mode; and if not, the articles to be delivered are dispersedly conveyed to the picking position from the storage position of the shelf through the second shelf. The first shelf may be a shelf without a shelf grid or with no layering, or a shelf with a small number of layers or with a small shelf grid, such as a tray shelf, so as to collectively store and transport a certain kind of goods. The second shelf can be a multi-layer, multi-compartment shelf to facilitate storage and handling of a variety of different items.

It should be noted that the first shelf and the second shelf not only have the function of carrying articles, but also have the function of storing articles. Comparing the first shelf and the second shelf with the same size, the first shelf has no grids and is not layered, or the first shelf has fewer layers or has fewer grids, so that the first shelf stores more articles, and the first shelf can transport and store more articles in a centralized manner. Thus, the number of times of warehousing and/or ex-warehouse of the articles (that is, the number of times of warehousing and/or ex-warehouse of the shelves) can be reduced by collectively transporting the articles by the first shelf. Therefore, the method can effectively reduce the warehousing times and/or ex-warehousing times of the goods shelf, thereby reducing the workload of the unmanned vehicle.

In embodiments of the present invention, "concentrating" is relative to "dispersing," and "concentrating" refers to: storing each kind of article on a first shelf in a centralized manner, wherein each first shelf is generally used for storing a few kinds of articles, such as one kind of article, two kinds of articles and the like; "disperse" means: each item is stored discretely on a plurality of second shelves, each of which typically stores a plurality of items.

Fig. 1 is a schematic diagram of a main flow of an inventory scheduling method according to an embodiment of the present invention. As an embodiment of the present invention, as shown in fig. 1, the inventory scheduling method may include:

step 101, judging whether the stock of the articles to be warehoused is smaller than a stock threshold value; if yes, go to step 102; if not, the process is ended.

In this step, it is necessary to determine whether the stock level of a certain article is lower than the stock threshold of the article, and if so, it indicates that the stock level of the article is lower than the preset stock threshold, and the article is determined to be an article to be put in storage. It should be noted that the inventory threshold values for different kinds of items may be different, and the inventory threshold values for various items may be preset.

In the step, whether the stock quantity of the articles to be warehoused on the second shelf is smaller than the stock threshold value can be further judged; if yes, go to step 102; if not, the process is ended.

Step 102, judging whether the warehousing quantity of the articles to be warehoused is greater than or equal to a warehousing threshold value for storing the articles on a first shelf; if yes, go to step 103, otherwise go to step 104.

The first shelf may be a shelf without a shelf grid or with no layering, or a shelf with a small number of layers or with a small shelf grid, such as a tray shelf, so as to collectively store and transport a certain kind of goods. Note that the first shelf is not limited to collectively carrying a certain kind of article, and may carry two kinds of articles or three kinds of articles. In short, the first rack can carry a small number of types of articles at one time of warehousing/ex-warehousing, and is suitable for centralized carrying of articles.

Because the first goods shelf has no goods grids and is not layered (or the number of layers is less or the goods grids are less), the quantity of the stored goods on the first goods shelf is more, and the warehousing times of the goods can be reduced by intensively carrying the goods on the first goods shelf. Moreover, when the same quantity of articles are stored, the first shelf is used, so that the storage space can be saved.

In order to improve the utilization rate of the first shelf, it is necessary to determine whether the warehousing quantity of the articles to be warehoused is greater than or equal to the warehousing threshold value for storing the articles on the first shelf. Specifically, the warehousing threshold is the maximum number of the first shelves storing the articles to be warehoused × percentage, and the percentage is set in advance, for example, 95%, 93%, 90%, 88%, 80%, and the like. It should be noted that the maximum number of different items stored on the first shelf may be different, but the same percentage may be set, and thus the warehousing thresholds for different items stored on the first shelf may be different. Of course, different percentages may be preset for each article.

And 103, intensively carrying the articles to be warehoused from the upper rack position to the rack storage position through the first rack.

If the warehousing quantity of the articles to be warehoused is larger than or equal to the warehousing threshold value of the first shelf for storing the articles, the warehousing quantity of the articles to be warehoused meets the requirement of the lowest quantity of the first shelf, the articles to be warehoused can be collectively lifted to the first shelf, and the articles to be warehoused are collectively conveyed to the shelf storage position from the shelf position through the first shelf. Specifically, the first goods shelf can be conveyed to the upper goods shelf position from the goods shelf storage position through the unmanned vehicle, the staff collectively puts the goods to be put in storage on the first goods shelf, and after putting the goods on the shelf is completed, the unmanned vehicle moves the first goods shelf back to the goods shelf storage position from the upper goods shelf position to complete the goods storage.

For example, the warehousing quantity of the articles to be warehoused needs one first shelf, only one first shelf is needed to be warehoused, and meanwhile, the transportation task is completed by warehousing the unmanned vehicles once, so that the warehouse working efficiency can be greatly improved, and the unmanned vehicle resources and the operation cost are saved. If the warehousing quantity of the articles to be warehoused is large, a plurality of first shelves are needed for centralizing the shelves, and the embodiment of the invention is not limited to one first shelf.

The unmanned vehicle is as follows: the goods shelves (namely the first goods shelf and the second goods shelf) where the goods are carried are moved from the goods shelf storage position to the goods picking position/goods loading position, and then the goods shelves are moved back to the automatic equipment of the goods shelf storage position from the goods picking position/goods loading position. The embodiment of the invention is only described by taking the unmanned vehicle as an example, and the unmanned vehicle can be replaced by other transportation equipment.

And 104, dispersedly conveying the articles to be warehoused from the upper rack position to the rack storage position through a second rack.

If the warehousing quantity of the articles to be warehoused is smaller than the warehousing threshold value of the first shelf for storing the articles, the warehousing quantity of the articles to be warehoused does not meet the minimum quantity requirement of the first shelf, the articles to be warehoused can be dispersedly erected on the second shelves, and the articles to be warehoused are dispersedly transported to the shelf storage position from the shelf position through the second shelves.

The second shelf can be a multi-layer, multi-compartment shelf to facilitate storage and handling of a variety of different items. Specifically, the second goods shelves can be conveyed to the upper shelf position from the goods shelf storage position through the unmanned vehicle, the workers dispersedly rack the goods to be warehoused on the plurality of second goods shelves, and after the goods are loaded, the second goods shelves are moved back to the goods shelf storage position from the upper shelf position through the unmanned vehicle, and the goods are warehoused.

Generally, the number of the second racks is plural, for example, the second rack 1, the second rack 2, and the second rack n, so that the items to be put in storage can be scattered and erected on the n second racks, and then the n second racks can be moved from the loading position to the rack storage position. Specifically, a plurality of items may be put on one second shelf according to a pick-up list, historical sales data, and the like, and one item may be scattered on a plurality of second shelves to reduce the number of warehousing of the second shelves, thereby reducing the workload of the unmanned vehicle.

According to the various embodiments, the technical means that if the warehousing quantity of the articles to be warehoused is greater than or equal to the warehousing threshold value of the first shelf for storing the articles is adopted, the articles to be warehoused are conveyed from the upper shelf position to the shelf storage position in a centralized manner through the first shelf, so that the problem of large warehousing times of the shelves is solved. That is to say, the prior art adopts the scattered shelving strategy, and the warehousing of bulk goods can increase the workload of high load to the unmanned vehicle. The invention reduces the warehousing times of articles (namely goods shelves) by centralizing the shelves, thereby reducing the workload of the unmanned vehicle.

Moreover, the first shelf is used to save the storage space when the same quantity of articles are stored. Therefore, the method provided by the embodiment of the invention can increase the storage capacity of goods in the storehouse, save the storage space of the storehouse, improve the operation efficiency of transportation equipment (such as unmanned vehicles), facilitate the management of goods and increase the storage capacity of certain goods. For example, good goods can be put in/out of the warehouse in large quantities via the first shelf.

As still another embodiment of the present invention, the step 103 may include:

When a certain article is warehoused in a large batch, a plurality of first shelves may be required to be warehoused in a centralized manner, and therefore in this embodiment, the number of the first shelves required for carrying the article to be warehoused is calculated according to the warehousing number of the article to be warehoused and the maximum number of the articles stored in the first shelves, so that the number of the articles stored in each first shelf is greater than or equal to the warehousing threshold value of the first shelf for storing the article. Preferably, the items are stored on each first shelf in a saturated state, i.e. the storage quantity on each first shelf is the maximum quantity of the first shelf for storing the items to be warehoused. Then, most of the articles to be warehoused are collectively conveyed from the upper rack position to the rack storage position through the first rack in a saturated state, and the rest of the articles to be warehoused are dispersedly conveyed from the upper rack position to the rack storage position through the second rack. It should be noted that the number of the remaining items to be warehoused is less than the warehousing threshold of the first shelf for storing the items.

Therefore, according to the method provided by the embodiment of the invention, the first shelf and the second shelf are used for warehousing at the same time, so that the respective characteristics and advantages of the first shelf and the second shelf can be fully exerted, and the warehousing efficiency of the articles is effectively improved.

Fig. 2 is a schematic diagram of a main flow of an inventory scheduling method according to a referential embodiment of the present invention, and the inventory scheduling method may include:

step 201, judging whether the warehouse-out quantity of the articles to be warehouse-out is larger than or equal to a warehouse-out threshold value of the first shelf for storing the articles; if yes, go to step 202; if not, go to step 203.

When the articles are delivered from the warehouse, it is necessary to determine whether the delivery quantity of the articles to be delivered from the warehouse is greater than or equal to a delivery threshold value for storing the articles on the first shelf, specifically, the delivery threshold value is the maximum quantity x percentage of the articles to be delivered stored on the first shelf, and the percentage is preset, for example, 95%, 93%, 90%, 88%, 80%, and the like. It should be noted that the maximum number of different items stored on the first shelf may be different, but the same percentage may be set, and thus the ex-warehouse threshold for different items stored on the first shelf may be different. Optionally, the ex-warehouse threshold in this step may be the same as or different from the in-warehouse threshold in step 102.

Because the first shelf has no grids and is not layered (or the number of layers is less or the number of grids is less), the number of the articles stored on the first shelf is larger, and the times of delivery of the articles can be reduced by intensively carrying the articles through the first shelf.

And 202, collectively transporting the articles to be delivered from the shelf storage position to the picking position through the first shelf.

If the warehouse-out quantity of the articles to be warehouse-out is larger than or equal to the warehouse-out threshold value of the first goods shelf for storing the articles, the warehouse-out quantity of the articles to be warehouse-out meets the requirement of the lowest quantity of the first goods shelf, and the articles to be warehouse-out can be conveyed from the goods shelf storage positions to the goods picking positions in a centralized mode through the first goods shelf, so that centralized warehouse-out is carried out. Specifically, can carry first goods shelves to the goods position of choosing from goods shelves storage position through unmanned car, the staff accomplishes the goods and puts off the shelf after, is moved back to goods shelves storage position from the goods position of choosing by unmanned car again, accomplishes article and goes out of the warehouse.

For example, the warehouse-out quantity of the articles to be warehoused needs one first shelf, only one first shelf is needed to be warehoused, and meanwhile, the transportation task is completed by once warehouse-out of the unmanned vehicle, so that the warehouse working efficiency can be greatly improved, and the unmanned vehicle resources and the operation cost are saved. If the number of the articles to be delivered is large, a plurality of first shelves are needed for centralized delivery, and the embodiment of the invention is not limited to one first shelf.

And 203, dispersedly transporting the goods to be delivered from the shelf storage position to the picking position through the second shelf.

If the delivery quantity of the articles to be delivered is smaller than the delivery threshold value of the first goods shelf for storing the articles, which indicates that the delivery quantity of the articles to be delivered does not meet the minimum quantity requirement of the first goods shelf, the articles to be delivered can be dispersedly transported from the goods shelf storage positions to the goods picking positions through the plurality of second goods shelves, so that the articles to be delivered are dispersedly delivered. Specifically, the second goods shelf can be conveyed to the goods sorting position from the goods shelf storage position through the unmanned vehicle, and after the workers finish unloading goods, the second goods shelf is conveyed back to the goods shelf storage position from the goods sorting position through the unmanned vehicle, so that goods are delivered out of the warehouse.

Generally, the number of the second racks is plural, for example, the second rack 1, the second rack 2, and the second rack n, so that the articles can be distributed and delivered from the warehouse through the n second racks.

According to the various embodiments, the technical means that if the number of the articles to be delivered is greater than or equal to the delivery threshold value of the first shelf for storing the articles, the first shelf collectively transports the articles to be delivered from the storage space of the shelf to the picking space, so that the problem of high delivery frequency of the shelf is solved. That is, the prior art adopts the scattered delivery strategy, and the delivery of large quantities of goods will increase the workload of high load for the unmanned vehicle. The invention reduces the times of goods (namely goods shelves) to be delivered out of the warehouse by a centralized delivery way, thereby reducing the workload of the unmanned vehicle.

As another embodiment of the present invention, the step 202 may include:

intensively carrying most of articles to be delivered from a shelf storage position to a goods picking position through a first shelf; and dispersedly carrying the rest of the goods to be delivered from the shelf storage position to the picking position through the second shelf.

When a certain article is delivered in a large batch, a plurality of first shelves may be required to be delivered in a centralized manner, and therefore, in this embodiment, the number of the first shelves required for transporting the article to be delivered is calculated according to the delivery number of the article to be delivered and the actual storage number of the article stored in the first shelf. Then, most of the articles to be delivered are collectively conveyed from the shelf storage position to the picking position through the first shelf, and the rest of the articles to be delivered are dispersedly conveyed from the shelf storage position to the picking position through the second shelf. It is noted that the number of remaining items to be discharged is smaller than the actual number of items stored on the first shelf. Generally, the actual number of items stored on the first shelf is determined by the time of warehousing, and the actual number of items stored on each first shelf may be the same or different. When a plurality of first shelves are selected for collective delivery, all the articles are delivered in a collective manner as much as possible.

Therefore, according to the method provided by the embodiment of the invention, the first goods shelf and the second goods shelf are used for delivery, so that the characteristics and advantages of the first goods shelf and the second goods shelf can be fully exerted, and the delivery efficiency of the goods is effectively improved.

As another embodiment of the present invention, the step 202 may include:

In this embodiment, the remaining portion of the items to be delivered is restocked from the first shelf to the second shelf to empty the items on the first shelf.

Fig. 3 is a schematic diagram of a main flow of an inventory scheduling method according to another referential embodiment of the present invention, and the inventory scheduling method may include:

step 301, judging whether the warehouse-out quantity of the articles to be warehoused is greater than or equal to a warehouse-out threshold value of the first shelf for storing the articles; if yes, go to step 302; if not, go to step 303;

step 302, transporting the goods to be delivered from the shelf storage position to a picking position through a first shelf in a centralized manner;

step 303, judging whether the storage quantity of the articles to be delivered stored on the second shelf is more than or equal to the delivery quantity of the articles to be delivered; if not, go to step 304 first, then go to step 305; if yes, go to step 305;

304, replenishing goods to be delivered to a second shelf through the first shelf;

and 305, dispersedly transporting the goods to be delivered from the shelf storage position to the picking position through the second shelf.

When the quantity of the articles to be delivered is smaller than the delivery threshold value of the first goods shelf for storing the articles, whether the storage quantity of the articles to be delivered stored on the second goods shelf is larger than or equal to the delivery quantity of the articles to be delivered is continuously judged, if yes, the storage quantity stored on the second goods shelf meets the required delivery quantity, and the articles to be delivered are directly and dispersedly conveyed from the storage positions of the goods shelves to the goods picking position through the second goods shelf. If not, the inventory does not meet the required quantity for ex-warehouse, an emergency replenishment task is triggered (the replenishment task triggered by the insufficient inventory of a certain commodity is found when the ex-warehouse production is carried out in the warehouse, and the priority is highest), specifically: and supplementing the goods on the first goods shelf to the second goods shelf, wherein the quantity of the supplemented goods is the total stock on the first goods shelf, and after the supplement is finished, reselecting the second goods shelf for delivery.

Therefore, the method provided by the embodiment of the invention adds the step of replenishing goods from the first shelf to the second shelf, solves the problem that the warehouse has insufficient inventory and only replenishes the inventory by moving the warehouse, ensures the commodity circulation from the first shelf to the second shelf and ensures the smooth production of the warehouse. In addition, the original warehousing scattered shelving strategy is used in the replenishment process, so that the original consistency of the management of the second shelf on the commodities is kept.

Fig. 4 is a schematic diagram of a main flow of an inventory scheduling method according to still another referential embodiment of the present invention, and the inventory scheduling method may include:

step 401, judging whether the warehouse-out quantity of the articles to be warehouse-out is greater than or equal to a warehouse-out threshold value of the first shelf for storing the articles; if yes, go to step 302; if not, go to step 303;

step 402, transporting the goods to be delivered from the shelf storage position to a picking position in a centralized manner through a first shelf;

step 403, judging whether the storage quantity of the articles to be delivered stored on the second shelf is greater than or equal to the delivery quantity of the articles to be delivered; if not, executing steps 404, 405 and 406 in sequence; if yes, go to step 407;

step 404, transporting the goods to be delivered from the storage position of the shelf to a goods replenishment source position through the first shelf, and transporting the second shelf from the storage position of the shelf to a goods replenishment destination position;

step 405, all the goods to be delivered from the first shelf are put on the second shelf

Step 406, moving the first shelf back to the shelf storage position, and moving the second shelf back to the shelf storage position or to the picking position;

in step 407, the articles to be delivered are dispersedly transported from the shelf storage to the picking location via the second shelf.

If the storage quantity of the articles to be delivered stored on the second shelf is smaller than the delivery quantity of the articles to be delivered, an emergency replenishment task from the first shelf to the second shelf is triggered, and the replenishment quantity is the total stock quantity on the first shelf. The unmanned vehicle carries the first goods shelf from the goods shelf storage position to the replenishment source position, simultaneously selects the second goods shelf 1, the second goods shelf 2 and the second goods shelf n by dispersing and putting on the shelves, and then carries the selected second goods shelf 1, the second goods shelf 2 and the second goods shelf n from the goods shelf storage position to the replenishment destination position; the goods in the first goods shelf are completely supplemented to the second goods shelf in a manual picking mode, the supplement is completed, the first goods shelf is moved back to the goods shelf storage position by the unmanned vehicle, and the second goods shelf is moved back to the goods shelf storage position or is moved to the goods picking position.

In addition, in one embodiment of the present invention, the detailed implementation of the inventory scheduling method is described in detail in the inventory scheduling method, so that the repeated description is not repeated here.

Fig. 5 is a schematic diagram of main modules of an inventory scheduling device according to an embodiment of the present invention, and as shown in fig. 5, the inventory scheduling device includes an warehousing module 501, where the warehousing module 501 determines whether a warehousing quantity of articles to be warehoused is greater than or equal to a warehousing threshold for storing the articles on a first shelf; if yes, the articles to be warehoused are conveyed from the upper rack position to the rack storage position in a centralized mode through the first rack; and if not, dispersedly transporting the articles to be warehoused from the upper rack position to the rack storage position through the second rack.

Therefore, the technical means that if the warehousing quantity of the articles to be warehoused is greater than or equal to the warehousing threshold value for storing the articles on the first shelf, the articles to be warehoused are conveyed from the upper shelf position to the shelf storage position in a centralized manner through the first shelf is adopted, so that the problem that the warehousing frequency of the shelf is large is solved. That is to say, the prior art adopts the scattered shelving strategy, and the warehousing of bulk goods can increase the workload of high load to the unmanned vehicle. The invention reduces the warehousing times of articles (namely goods shelves) by centralizing the shelves, thereby reducing the workload of the unmanned vehicle.

When a certain article is warehoused in a large batch, a plurality of first shelves may be required to be warehoused in a centralized manner, and therefore in this embodiment, the number of the first shelves required for carrying the article to be warehoused is calculated according to the warehousing number of the article to be warehoused and the maximum number of the articles stored in the first shelves, so that the number of the articles stored in each first shelf is greater than or equal to the warehousing threshold value of the first shelf for storing the article. Preferably, the items are stored on each first shelf in a saturated state, i.e. the storage quantity on each first shelf is the maximum quantity of the first shelf for storing the items to be warehoused. Then, most of the articles to be warehoused are collectively conveyed from the upper rack position to the rack storage position through the first rack in a saturated state, and the rest of the articles to be warehoused are dispersedly conveyed from the upper rack position to the rack storage position through the second rack. Therefore, the device provided by the embodiment of the invention can give full play to the respective characteristics and advantages of the first shelf and the second shelf by simultaneously using the first shelf and the second shelf for warehousing, and effectively improves the warehousing efficiency of articles.

Optionally, the apparatus further includes a delivery module 502, where the delivery module 502 determines whether the delivery quantity of the items to be delivered is greater than or equal to a delivery threshold value of the first shelf for storing the items; if yes, the goods to be delivered are conveyed from the goods shelf storage position to the goods picking position through the first goods shelf in a centralized mode; and if not, the articles to be delivered are dispersedly conveyed to the picking position from the storage position of the shelf through the second shelf. Therefore, the technical means that if the delivery quantity of the articles to be delivered is larger than or equal to the delivery threshold value of the first goods shelf for storing the articles, the articles to be delivered are conveyed from the storage positions of the goods shelves to the goods picking position in a centralized manner through the first goods shelf is adopted, so that the problem of more delivery times of the goods shelves is solved. That is, the prior art adopts the scattered delivery strategy, and the delivery of large quantities of goods will increase the workload of high load for the unmanned vehicle. The invention reduces the times of goods (namely goods shelves) to be delivered out of the warehouse by a centralized delivery way, thereby reducing the workload of the unmanned vehicle.

alternatively, the first and second electrodes may be,

Therefore, the device provided by the embodiment of the invention adds the step of replenishing goods from the first shelf to the second shelf, solves the problem that the stock in the warehouse is insufficient and is replenished only by moving the warehouse, ensures the commodity circulation from the first shelf to the second shelf and ensures the smooth production of the warehouse. In addition, the original warehousing scattered shelving strategy is used in the replenishment process, so that the original consistency of the management of the second shelf on the commodities is kept.

According to the various embodiments, the technical means that if the warehousing quantity of the articles to be warehoused is greater than or equal to the warehousing threshold value of the first shelf for storing the articles is adopted, the articles to be warehoused are conveyed from the upper shelf position to the shelf storage position in a centralized manner through the first shelf, so that the technical problem that the warehousing/ex-warehouse times of the shelf are more is solved, and the warehousing/ex-warehouse times of the articles (namely the shelf) are reduced by the centralized upper shelf manner, so that the workload of the unmanned vehicle is reduced; the storage capacity of goods in the storehouse can also be increased, the storage space of the storehouse is saved, the operating efficiency of transportation equipment (such as an unmanned vehicle) can also be improved, the management of articles is facilitated, and the storage capacity of certain articles can be increased.
