In the picking storage area 1001, the layout of the shelves is placed in a back-to-back manner by two or four groups of shelves, picking lanes are reserved among the shelves, and the picking storage area 1001 is used for placing first-class cargos, wherein the first-class cargos are specifically cargos with a heat value larger than or equal to a preset heat threshold, the heat value can be understood as the probability of the cargos being hit, and the higher the heat value is, the higher the probability of the cargos being hit is. Further, a lot or priority of shipment is stored in the pick storage 1001, and in actual application, it may be determined which shipment is required according to the acquired order.

In dense storage 1002, shelves have a higher density than shelves in the pick storage, shelves are immediately adjacent to each other, and in dense storage 1002, no or fewer pick lanes are provided between shelves. In the dense storage area 1002, the second type of cargo is used to store the second type of cargo, where the second type of cargo specifically refers to the cargo having the heat value less than the preset heat threshold, that is, the small amount of the late-sell cargo is stored in the dense storage area.

In one embodiment of the present application, the dense storage area is usually in the form of multiple sets of shelves for storing more goods, the shelves are densely arranged, and when the storage area is small (for example, the dense storage area can be used for placing 5-8 rows of shelves), no lane is arranged in the dense storage area, or only one lane is arranged between the shelves in the dense storage area. Preferably, when there is only one tunnel between shelves, in order to facilitate the transportation of the shelves inside the dense storage area, the tunnel may be disposed in the middle area of the dense storage area.

In another embodiment provided by the present application, when the inventory area is large enough (e.g., more than 20 rows of shelves may be placed in the dense storage area), at least two lanes may be disposed in the dense storage area 1002, and in order to store more goods, the number of rows of shelves between two adjacent lanes is greater than 4, for example, the number of rows of shelves between two adjacent lanes is 5, 6, 10, etc. The fewer the number of lanes, the greater the number of shelves and the more goods can be stored.

In practical application, the heat degree of the goods refers to that the goods are delivered in large quantity or with high delivery frequency, and the higher the heat degree value of the goods is, the higher the heat degree value of the corresponding goods shelf is, and the heat degree value of the goods is determined by at least one of the delivery frequency and the delivery quantity of the goods.

In the warehouse area shown in fig. 1, the picking stations are located on one side of the warehouse, the inventory area near the picking stations is the picking storage area, the area adjacent to the picking storage area, and the area far from the picking stations is the dense storage area. Fig. 1 is only a schematic illustration of a warehouse area provided by the present application, in practical application, the positions of the picking stations in the warehouse are not limited, and the picking stations may be disposed at two sides or around the warehouse, and the picking storage area and the dense storage area may be correspondingly adjusted, that is, the dense storage area is in the middle of the warehouse, and the picking storage areas are disposed at two sides or around the warehouse.

The positions of the dense storage area and the picking storage area are not limited, the distance between the picking storage area and the picking workstation is only required to be ensured to be smaller than that between the dense storage area and the picking workstation, the picking storage area is arranged at the position close to the picking workstation, and goods with higher heat value are placed, so that the picking efficiency of the goods is facilitated; the intensive storage area is arranged at a position far away from the picking workstation, goods with lower heat value are placed, the storage rate of the warehouse is conveniently improved, the picking efficiency is improved, the storage capacity of the warehouse is improved, and balance is achieved between storage and picking.

Furthermore, in practical application, the layer height of many warehouses is very high, and if only one layer of warehouse area is set, the warehouse space is wasted, so in another embodiment provided by the application, the system can be further provided with a plurality of layers of warehouse platforms in the warehouse area, and correspondingly, the dense storage areas can be positioned in at least one layer of warehouse platform.

For example, the warehouse may be provided as a stereoscopic warehouse, with multiple warehouse platforms, with elevators provided between the multiple warehouse platforms, for the pallet robot to handle the pallet moving between the multiple warehouse platforms. In a specific embodiment provided by the application, a picking workstation is arranged in a layer 1 storage platform, a picking storage area is arranged in the layer 1 storage platform, and a dense storage area is arranged on other storage platforms except the layer 1 storage platform.

In practical application, due to different orders of each day, the goods can be required to be adjusted in the goods shelves in the picking storage area and the dense storage area, for example, the goods A are not hit in the first day and can be placed in the dense storage area; on the next day it is hit, and the item a needs to be adjusted to the pick store waiting to be picked. Based on the above, a cargo handling workstation can be further arranged in the warehouse system, specifically, the cargo handling workstation is located between the picking storage area and the dense storage area, and the cargo handling workstation is used for sorting cargoes of the picking storage area to the dense storage area or sorting cargoes of the dense storage area to the picking storage area according to cargo handling tasks.

Specifically, taking the example of sorting the goods B from the picking storage area to the dense storage area, the system determines that no order hits the goods B according to the order for a period of time (for example, 24 hours) in the future, at this time, the goods B need to be moved from the picking storage area to the dense storage area, then a tally task can be generated, the dense storage shelves of the goods B in the dense storage area are determined, the shelf handling equipment is moved, the shelf where the goods B is located is handled to a tally workstation, meanwhile, the shelf handling equipment is moved to handle the hit dense storage shelves to the same tally workstation, the goods B is placed in the dense storage shelves, and then the dense storage shelves storing the goods B are moved back to the dense storage area, so as to finish the operation of sorting the goods in the picking storage area to the dense storage area.

In another specific embodiment provided by the application, taking the case of sorting goods C from a dense storage area to a picking storage area as an example, the system determines that the goods C hit the orders according to the order request, and the goods C are located in the dense storage area, so that the goods C need to be sorted from the dense storage area to the picking storage area in advance for facilitating picking, a cargo sorting task is generated, the dense storage shelves where the goods C are located are determined, the dense storage shelves are conveyed to a cargo sorting workstation, meanwhile, the corresponding picking shelves of the goods C in the picking storage area are determined, the picking shelves are conveyed to the cargo sorting workstation, in the cargo sorting workstation, the goods C are sorted from the dense storage shelves to the picking shelves, and then the picking shelves where the goods C are stored are conveyed back to the picking storage area, and thus the operation of sorting the goods in the dense storage area to the picking storage area is completed.

It should be noted that a person or a mechanical arm may be provided in the goods handling workstation, through which the process of goods handling is completed. The storage area is provided with a cargo management workstation, so that the position of a cargo box can be adjusted in real time according to orders, and the cargo box in the dense storage area is managed to a picking storage area as much as possible according to the condition that the orders hit the cargo box, so that the cargo picking efficiency is improved.

In one embodiment of the present application, the warehouse management system further includes one or more control servers 120, and a rack handling device 130.

The control server 120 is connected with the shelf handling device 130 in a wireless communication manner, a worker operates the control server 120 through the operation console 124, the control server 120 is a software system running on the server and having data storage and information processing capabilities, the control server 120 may include one or more servers, may be a centralized control architecture or a distributed computing architecture, the control server 120 has a processor 121 and a memory 122, and may have an order pool 123 in the memory 122, and order information is stored in the order pool 123.

The control server 120 is configured to hit at least one target shelf according to an order task, determine position information of each target shelf in the picking storage area and/or the dense storage area, and send the position information corresponding to each target shelf to the shelf handling device 130;

and a shelf handling device 130 for handling each target shelf to the picking workstation according to the position information of each target shelf.

In practical application, the control server is used for comprehensively processing order tasks, and can determine required goods according to the order tasks and further determine a target goods shelf corresponding to the goods, wherein the target goods shelf specifically refers to a goods shelf where goods hit by an order are stored.

Specifically, the control server is used for searching target shelves in the picking storage area according to target orders, and searching target shelves in the dense storage area from outside to inside under the condition that the target shelves are not hit in the picking storage area.

In practical application, the control server searches the target shelves in the warehouse area according to the order task, in order to improve the picking efficiency, searches in the dense storage area according to the mode of searching the preferential picking storage area, and searches in the order from the outside to the inside when searching in the dense storage area for convenience in carrying because of the large placement density of the shelves in the dense storage area, for example, 10 layers of shelves exist in the dense storage area, one side close to a roadway is the outside, one side far away from the roadway is the inside, and the search is preferentially performed in the order from the outside to the inside in the process of searching the target shelves.

In some warehouse situations, for example, a control server determines a target goods shelf according to the situation of an order in an order pool, and carries the goods shelf hit by the order to a picking stock area in advance, and carries the goods shelf hit by the order to a dense storage area when the position of the picking stock area is insufficient, and sorts the goods shelf hit by the order from outside to inside.

Specifically, the control server is configured to determine a shelf arrangement order of a target shelf in the inventory area according to an order sequence in the order task, and generate a shelf movement task based on the shelf arrangement order, where the target shelf is sequentially arranged according to an order sequence of a picking storage area, an outer side of a dense storage area, and an inner side of the dense storage area;

The goods shelf carrying equipment is used for carrying each target goods shelf to a specified position according to the goods shelf moving task.

The order sequence is determined according to the order arrival time point in the order task.

In practical application, after receiving the order task, the control server determines the shelf arrangement order of the target shelf hit by each order in the stock area according to the order sequence in the order task, and places the target shelf hit first in the picking storage area first, and places the target shelf in the dense storage area after the picking storage area is full, and further, in order to improve the picking efficiency, the target shelf is still arranged in the dense storage area according to the order from the outer side of the dense storage area to the inner side of the dense storage area.

For example, 10 shelves may be placed in total in the picking storage area, and when the control server determines 15 shelves according to the order task, according to the order sequence, the discharging positions of the 10 target shelves hit by the order with the front order arrival time point are selected in the picking storage area, and the discharging positions of the last 5 target shelves are determined in the dense storage area. When more than 5 rows of shelves are arranged in the dense storage area, 5 target shelves positioned in the dense storage area are respectively positioned in the first row of the 5 rows of shelves; when there are fewer than 5 rows of shelves in the dense storage area, the 5 target shelves in the dense storage area are preferably arranged in a first row of shelves in each row and then in a second row of shelves in each row.

When order tasks are executed according to order sequence, 10 target shelves in a picking storage area are sequentially hit according to order sequence, and 5 target shelves in a dense storage area are hit, so that the aim of quick picking is fulfilled.

In practical application, the goods shelf handling equipment carries the target goods shelf from the picking storage area or the dense storage area to the picking workstation for order task picking, and when the picking is completed, the goods shelf is required to be carried back to the picking storage area or the dense storage area, and at the moment, the position of carrying the target goods shelf is required to be determined according to the demand information of goods on the target goods shelf.

Specifically, the control server is further configured to determine return position information of the target goods according to the demand information of the goods on the target goods shelf after the goods in the target goods shelf are picked, where the demand information of the goods is determined according to the goods hit information in the order task;

Determining that the returning position information of the target goods shelf is a picking storage area under the condition that the demand information is larger than a preset demand threshold value;

And under the condition that the demand information is smaller than or equal to the demand threshold value, determining that the return position information of the target goods shelf is a dense storage area.

In practical application, after the goods in the target goods shelf perform the picking task at the picking workstation, the goods need to be carried back to the stock area, specifically, the returning position information of the target goods needs to be determined according to the demand information of the goods on the target goods shelf, and the returning position information specifically refers to whether the target goods shelf is returned to the picking storage area or the dense storage area.

The demand information of the goods specifically refers to goods hit information in order tasks, for example, goods 1 and goods 2 are on a target goods shelf, when a certain order 1 is executed, the order 1 hits the goods 1, and then the target goods shelf is carried to a picking workstation to execute goods picking. The subsequent orders 4 hit the goods 2, at this time, the goods 2 on the target shelf need to be picked in the subsequent orders, at this time, the target shelf can be transported to the picking storage area, and if the goods on the target shelf are not hit any more in the subsequent orders, which means that the goods on the target shelf are not needed temporarily, the target shelf can be transported to the dense storage area.

In practical application, the demand information of the goods on the target goods shelf is specifically information that the goods on the target goods shelf are hit in a subsequent order according to the fact that when the number of times that the goods on the target goods shelf are hit is larger, the value of the demand information is larger, and when the value of the demand information of the goods on the target goods shelf is larger than a preset demand threshold value, the fact that the goods on the target goods shelf are needed in the subsequent order task is higher is indicated, and return position information of the target goods shelf can be determined to be a picking storage area; when the value of the demand information of the goods on the target goods shelf is smaller than or equal to the preset demand threshold value, the degree that the goods on the target goods shelf are required in the subsequent order task is lower, and the returning position information of the target goods shelf can be determined to be a dense storage area.

After the return position information of the target shelf is determined, the shelf handling device may be scheduled to handle the target shelf to the return position information.

In practical application, when the target goods shelf is located in the picking storage area, two groups of goods shelves or four groups of goods shelves are arranged back to back in the picking storage area, if the two groups of goods shelves are arranged, the goods shelf handling equipment is directly scheduled to carry, if the four groups of goods shelves are arranged back to back, if the hit target goods shelf is an inner goods shelf, the two goods shelf handling equipment can be scheduled, one of the goods shelves is moved away from the outer goods shelf, and the other goods shelf is moved out of the inner goods shelf.

The dense storage areas are provided with a plurality of groups of shelves, when the target shelf is positioned at the inner side of the dense storage areas, the plurality of groups of shelves are blocked, and based on the blocking, the control server is further used for determining the blocking shelf corresponding to the target shelf and determining shelf carrying equipment when the target shelf is positioned at the inner side of the dense storage areas;

and the goods shelf carrying equipment is used for taking the blocking goods shelf out of the dense storage area, carrying the target goods shelf from the dense storage area to a target position and carrying the blocking goods shelf back to the dense storage area.

In this case, when the target shelf determined by the control server is located inside the dense storage area, a blocking shelf corresponding to the target shelf is determined at the same time, and a shelf handling device for handling the blocking shelf and the target shelf is determined at the same time, where the blocking shelf specifically refers to a shelf that blocks the target shelf from being handled, for example, the target shelf is located in the 5 th row of a certain column of shelves, and four shelves of the 1 st to 4 th rows are blocking shelves; when the target pallet is located in the 10 th row of a certain column of pallets, nine pallets of the 1 st to 9 th rows are all blocking pallets, and it is necessary to determine pallet transporting equipment for transporting the blocking pallet and pallet transporting equipment for transporting the target pallet.

The blocking goods shelf is taken out from the dense storage area by goods shelf conveying equipment for conveying the blocking goods shelf, then the goods shelf conveying equipment for conveying the goods shelf is used for conveying the goods shelf to the target position from the dense storage area, and then the goods shelf conveying equipment for conveying the blocking goods shelf is used for conveying the blocking goods shelf back to the dense storage area.

In practice, the barrier pallet can be handled in two ways:

when the number of the goods shelf handling devices in the warehouse area is enough, a control server is used for determining a first number of the blocking goods shelf and determining a first goods shelf handling device corresponding to the first number and a second goods shelf handling device corresponding to the target goods shelf;

the first goods shelf handling device is used for taking the blocking goods shelf out of the dense storage area;

the second goods shelf carrying device is used for carrying the target goods shelf from the dense storage area to a target position;

the first pallet handling device is further configured to handle the blocking pallet back to the dense storage area.

In this case, the number of shelf handling devices in the warehouse area is sufficient, and after the control server determines the target shelf, the control server may determine the first number of blocking shelves and the first number of blocking shelves at the same time, where the first number specifically refers to the specific number of blocking shelves, for example, the first number of blocking shelves is 4 if the target shelf is in row 5, and the first number of blocking shelves is 9 if the target shelf is in row 10. In the present embodiment, the first number may be regarded as N.

After the N blocking racks are determined, N first rack carrying devices and 1 second rack carrying device are determined at the same time, wherein the first rack carrying device specifically refers to a rack carrying device for carrying the blocking racks, and the second rack carrying device specifically refers to a carrying device for carrying the target racks. Each first goods shelf carrying device corresponds to one blocking goods shelf, the blocking goods shelf is carried out of the dense storage area by the first goods shelf carrying device, a carrying channel is reserved for the target goods shelf, the target goods shelf is carried to the target position from the dense storage area by the second goods shelf carrying device, and then the carried blocking goods shelf is carried back to the dense storage area by the first goods shelf carrying device. Thus, the operation of transporting the target pallet located inside the dense storage area to the target position is completed.

In addition, a condition that the shelf carrying equipment is insufficient exists in the storage area, and based on the condition, the control server is used for determining a first quantity of the blocking shelves and determining a second quantity of first shelf carrying equipment and second shelf carrying equipment corresponding to the target shelf, wherein the second quantity is smaller than the first quantity;

The first goods shelf carrying device is used for taking the blocking goods shelf out of the dense storage area and placing the blocking goods shelf in a temporary goods shelf storage position, wherein the temporary goods shelf storage position is positioned in the dense storage area and/or the picking storage area;

the second goods shelf carrying device is used for carrying the target goods shelf from the dense storage area to a target position;

the first pallet handling device is further configured to handle the blocking pallet from the temporary pallet storage location back to the dense storage area.

In this case, after determining the first number N of blocking racks, the control server finds that the number of first rack carrying devices that can be called in the storage area is less than N, and calls N first rack carrying devices according to the situation in the storage area, where N < N, for example, the blocking racks have 9, and the number of first rack carrying devices is 5.

Meanwhile, a temporary goods shelf storage position is arranged in the storage area, the temporary goods shelf storage position specifically refers to the position of a temporary storage goods shelf, the temporary goods shelf storage position is used for coordinating and temporarily storing goods shelves which need to be temporarily parked, after n first goods shelf handling equipment is determined, the blocking goods shelves can be handled from the dense storage area to the temporary goods shelf storage position by the first goods shelf handling equipment, then the blocking goods shelves in the dense storage area are continuously handled, and therefore the blocking goods shelves are handled from the dense storage area, a handling channel is reserved for a target goods shelf, and then the target goods shelf is handled from the dense storage area to the target position by the second goods shelf handling equipment. And finally, sequentially carrying the blocking shelves back to the dense storage area by n first shelf carrying devices.

Referring to fig. 2, fig. 2 is a schematic diagram of a system architecture of another warehouse dispatching system according to the present application. Temporary shelf storage locations are provided at locations of the pick storage areas 1001 near the dense storage areas 1002.

As shown in fig. 2, in the pick store 1001, shelves are arranged in single, double, and triple rows, leaving a pick lane between shelves for operation of shelf handling equipment. In the dense storage area 1002, shelves are stored in a dense arrangement, no sorting passage is provided, and 9 rows of shelves are provided in a dense arrangement in total.

Goods that are preferentially delivered are stored in the shelves of the pick store 1001, and small amounts of goods that are at rest are stored in the dense store.

The control server 120 hits the goods on the target shelf according to the order task, prioritizes the goods hit on the shelf in the pick storage area 1001, hits the target shelf again from the dense storage area 1002 when the goods are not hit in the pick storage area 1001, and searches for the target shelf in the dense storage area in the order from the outside to the inside.

When the hit target pallet is located inside the dense storage area 1002, it may be determined that there are N blocking pallets outside the target pallet, and when there are N pallet handling devices operating in the inventory area, N pallet handling devices may be called to remove the N blocking pallets from the dense storage area, and 1 pallet handling device may be called to handle the target pallet from the dense storage area 1002 to the picking workstation 110, and then the N blocking pallets are transported back to the dense storage area.

When the number of the available shelf handling devices in the stock area is less than N, the shelf handling devices may be invoked to take the blocking shelf out of the dense storage area, temporarily place the blocking shelf in the temporary shelf storage position, invoke one shelf handling device to handle the target shelf dense storage area 1002 to the picking workstation 110, and finally, handle the N blocking shelves back to the dense storage area.

After the target shelf completes the picking task at the picking workstation 110, the control server may calculate the demand information of the target shelf according to the condition of the subsequent order task, when the subsequent order task will hit the goods on the target shelf, it may be determined that the target shelf is to be carried back to the picking storage area 1001, and if the subsequent order does not hit the goods on the target shelf, it may be determined that the target shelf is to be carried back to the dense storage area 1002.

According to the warehouse scheduling system provided by the application, the dense storage areas are distributed in the warehouse area, the picking storage areas are arranged in the area close to the picking workstation, the dense storage areas are arranged in the area far away from the picking workstation, the conventional goods shelves are arranged in the picking storage areas, picking roadways are arranged among the goods shelves, the density of the goods shelves arranged in the dense storage areas is higher than that of the goods shelves in the picking storage areas, namely, no roadway or a small number of roadways are arranged in the dense storage areas, and the storage efficiency in the dense storage areas is improved. Through the mode that intensive storage area and selecting storage area mix the setting, the warehousing ability of storage area has been promoted.

Referring to fig. 3, fig. 3 shows a flowchart of a warehouse scheduling method according to an embodiment of the present application, where the method is applied to a warehouse scheduling system, and the system includes a control server, a pallet handling device, a stock area, and a picking workstation, where the stock area includes a picking storage area and a dense storage area, the picking storage area and the dense storage area are provided with a plurality of pallets, and a distance between the picking storage area and the picking workstation is smaller than a distance between the dense storage area and the picking workstation.
