The portable wearable device may be a smart watch, smart bracelet, headset, or the like.
In one embodiment, as shown in FIG. 2, a pick order feeding method is provided, illustrated as applied to the computer device 102 example of FIG. 1, comprising the steps of:
step 202, obtaining a demand order parameter, and determining an inventory box to be taken out of the warehouse according to the demand order parameter.
Wherein the demand order parameters refer to related parameters in the demand order. The computer device feeds according to the demand order. In some embodiments, the demand orders require that the material be shipped in order boxes. The demand order parameters may include parameters such as the number of order boxes, the type of material in each order box, and the number of each material, which may be characterized in particular by SKUs (Stock Keeping Unit, stock units).
The stock box to be taken out of the warehouse is a material box which is commonly used in the warehouse industry, and the warehouse is a material box warehouse for storing the material box. The stock box to be taken out of the warehouse stores a plurality of materials, and the materials can be singly put in a single type or mixed in multiple types. And when a demand order exists, the corresponding stock box is delivered from the warehouse according to the demand order parameters.
After the stock boxes to be taken out of the warehouse are taken out of the warehouse, the stock boxes to be taken out of the warehouse are transported to a picking workstation, and materials selected from the stock boxes to be taken out of the warehouse are packed into corresponding order boxes.
Step 204, the first lot of inventory boxes to be taken out of the warehouse is transported to the first level buffer, and the second lot of inventory boxes to be taken out of the warehouse is transported to the second level buffer.
The first-level cache refers to equipment for temporarily storing the inventory boxes to be delivered before the inventory boxes to be delivered are delivered to the picking workstation; the second-level cache is a first-level cache and is used for feeding the stock box to the first-level cache. The inventory boxes to be taken out of the warehouse in the second-level cache are firstly transported to the first-level cache, and then a picking workstation is supplied from the first-level cache.
And 206, continuing to issue the library tasks until all the library boxes to be subjected to library delivery are delivered before the library boxes in the primary cache and the secondary cache are consumed.
If the required order is completed by one delivery task, all the inventory boxes to be delivered are carried and delivered, and the delivery task is only delivered once.
By means of the two-stage cache mode, on one hand, the operation amount of vehicles in the warehouse corresponding to each ex-warehouse task can be increased, so that the carrying capacity of the vehicles in the warehouse can be fully mobilized, and a plurality of carrying vehicles in the warehouse are prevented from being idle; because the goods in the warehouse can be taken out when the warehouse is in warehouse, and can be put into the warehouse when the warehouse is in warehouse, when the warehouse executes the warehouse-out task, the warehouse-in task is generally not arranged in the same period, or the priority of the warehouse-in task at the same time is lowered, at the moment, a small amount of transport vehicles executing the warehouse-out task in time walk in a roadway in the warehouse, and the whole operation efficiency of the transport vehicles is influenced by occupying a path; compared with the conventional single-stage cache layout, the two-stage cache has more stock boxes which can be cached, so that the carrying quantity of corresponding one-time ex-warehouse tasks is more, the efficiency of the carrying vehicles in the ex-warehouse can be fully mobilized, the ex-warehouse can be completed in less time and the picking supply requirement of a period of time is met, and other tasks such as warehouse entering and warehouse moving can be carried out by freeing the carrying vehicles in the interval of the two ex-warehouse tasks, so that the overall working efficiency of the warehouse is improved;
on the other hand, two batches of stock boxes in the first-level cache and the second-level cache can be matched with each other, so that the problem of unbalance of large difference in picking time of each stock box in a single batch is solved, and the outage probability of a picking workstation is reduced; if the types of materials in the stock box are different, or the picking capacities of different picking stations are different, imbalance is easily generated during picking, so that the local stations enter a waiting state in advance; the layout of the two-stage cache has the advantage that more balanced combination can be performed by utilizing more stock boxes in two batches, so that the stock boxes distributed on the picking workstation and the stations thereof are more consistent in application, and the whole picking supply is more stable.
In one embodiment, the picking stations are plural; the demand order parameters also include the number of order boxes; determining a to-be-ex-warehouse inventory box corresponding to a picking workstation according to the demand order parameters, wherein the to-be-ex-warehouse inventory box comprises: acquiring the number of picking workstations; determining the total number of inventory boxes to be taken out of the warehouse according to the number of order boxes in the demand order parameters and the material type in each order box; and determining the inventory boxes to be taken out of the warehouse corresponding to each picking workstation according to the total number of the inventory boxes and the number of the picking workstations.
The total number of stock bins refers to the total number of stock bins to be taken out of the warehouse. Each stock bin includes a material of one material type, and the number of materials in each stock bin is plural.
The computer equipment determines the total number of stock boxes to be taken out of the warehouse according to the number of order boxes in the demand order parameters and the material type in each order box. Specifically, the computer device obtains a product value of the number of order boxes and the type of material in each order box, the product value characterizing the total type of material required in the demand order. Since the material data in the inventory boxes is often greater than the amount of material for the corresponding material type required in the order boxes. The computer device takes the product value as the total number of inventory bins to be taken out of the warehouse. The material in the stock box to be taken out of the warehouse can be ensured to meet the order requirement.
The computer equipment divides the total number of the stock boxes by the number of the picking workstations, and the obtained quotient is used as the stock box to be taken out of the warehouse corresponding to each picking workstation.
The carrying equipment refers to equipment such as a carrying vehicle, a robot and the like for conveying the inventory box to be taken out of the warehouse from the warehouse to the first-level cache or the second-level cache.
The carrying efficiency refers to the number of inventory boxes that can be carried by the carrying device per unit time. The carrying efficiency of each carrying device may be the same or different.
And the computer equipment determines the quantity of carrying equipment according to the total quantity of the inventory boxes to be delivered and the carrying efficiency, and the carrying equipment with the quantity of the carrying equipment is used for ensuring that the total quantity requirement of the inventory boxes to be delivered is met. Specifically, the picking time length of the stock boxes for picking the total number of the stock boxes is obtained, and as the stock boxes are simultaneously transported to the two-stage cache, the computer equipment determines the quotient of the total number of the stock boxes and the picking time length, and multiplies the obtained quotient by 2 to obtain the number of the stock boxes to be taken out in unit time. The calculation formula of the number of the stock boxes to be taken out of the warehouse in unit time is as follows:
ΔN=N1*（ΣΔni*Δhi）/T*2
wherein Δn represents the number of inventory boxes to be taken out of the warehouse per unit time, Δni represents the number of order box caches of the ith picking workstation, Δhi represents the number of material types of each order box in the ith picking workstation, and T represents the picking time of picking inventory boxes corresponding to the total number of inventory boxes.
In one embodiment, picking inventory bins delivered to respective picking workstations based on the type of material in each order bin and the quantity of material of each type of material in each order bin in the demand order parameters to obtain materials matching the demand order parameters includes: sorting out target stock boxes corresponding to the material types from the stock boxes of the corresponding picking workstations according to the material types in each order box and the material quantity of each material type in each order box in the demand order parameters; and selecting materials with the corresponding material quantity from the target stock box, packing the selected materials into the order box as materials matched with the demand order parameters, and completing the feeding process of the stock box to be taken out.
In one embodiment, the step of obtaining the first duration includes: acquiring a first conveying time length from the test inventory box in the second-level buffer memory to the first-level buffer memory and a second conveying time length from the test inventory box in the first-level buffer memory to the corresponding picking workstation; the test stock box is the same or similar to the shape and structure of the stock box to be taken out. The test inventory box is used to test the duration of the delivery of the inventory box by the delivery device.
The method for testing the conveying time length of the conveying equipment by the inventory box in advance is characterized in that the conveying time length is often determined by the conveying distance, the feeding interval time length is determined based on the conveying time length, the conveying time length of the inventory box conveyed by the conveying equipment is determined according to the actual condition of a feeding site, and the connection efficiency between warehouse feeding and two-stage buffer feeding is improved. The parameters obtained from the preliminary testing may also include a third conveyance time period for conveying the test inventory box from the warehouse to the primary cache, and a fourth conveyance time period for conveying the test inventory box from the warehouse to the secondary cache.
In one embodiment, the number of boxes corresponding to the first batch of to-be-picked inventory boxes is greater than or equal to a first safe buffer number, wherein the first safe buffer number is a ratio of a conveying time required by the first batch of to-be-picked inventory boxes to an average time required by a picking workstation to pick a single inventory box, and if the ratio is not an integer, the integer part is added with 1 to obtain a result; if the average picking time of a single stock box is 1min, and the conveying time required by the stock box to be taken out of the stock box in the first batch, namely the third conveying time is 3min, the first safety buffer number is 3, and at least 3 stock boxes are stored in the first-level buffer, so that the supply of a picking workstation can be ensured before the next replenishment.
Specifically, the first secure buffer number calculation formula is:
n1=（（Ti）max）/Δt）*k1
where n1 represents a first number of secure caches, and in some embodiments, the first cache has a rounded value of n1, ti represents a third shipping duration, Δt represents an average picking duration of a single bin, k1 represents a coefficient, and k1 may be selected according to the actual situation. Illustratively, k1 may be any one of values 1.1 to 1.2 to obtain some buffer margin to cope with some path collision avoidance, handling equipment failure, and other emergency situations in the transportation process.
Similarly, the number of bins corresponding to the second batch of bins to be taken out of the warehouse is greater than or equal to the second safe buffer number, the second safe buffer number is a ratio of the sum of the conveying time required by the second batch of bins to be taken out of the warehouse and the time required by the second buffer to transfer the bins to the first buffer to the average time required by the picking workstation to pick a single bin, and the calculation logic of the second safe buffer number is similar to that of the first safe buffer number.
The second safe buffer number calculation formula is:
n2=（（Tj）max+ΔT）/Δt）*k2
where n2 represents a second number of secure caches, and in some embodiments, the second cache has a rounded value of n2, tj represents a fourth shipping duration, Δt represents a first shipping duration, Δt represents an average picking duration of a single bin, k2 represents a coefficient, and k2 may be selected according to the actual situation. Illustratively, k2 may be any one of values 1.1 to 1.2.
