The automated equipment includes Automated robotic arm.

In yet another specific embodiment provided by the present application, the control server 110 is configured to determine the target high shelf 1301 where the target inventory container containing the order goods is currently located and the target picker where the target inventory container will be placed according to the order task. Rack 1302, the target picking rack 1302 has a storage position for placing the target inventory container, and simultaneously determines the target access device 140 for accessing the target inventory container and the target handling device for handling the target picking rack. device 150, and send an access instruction to the target access device 140, and send a transfer instruction to the target transfer device 150;

The target access device 140 is configured to move to the target high shelf 1301 in response to the access instruction, take out the target inventory container from the target high shelf 1301, and store the target inventory A container is placed in a storage location of said target picking shelf 1302;

The target transport device 150 is configured to transport the target picking rack 1302 on which the target inventory container is placed to a destination in response to the transport instruction.

In the first embodiment provided by this application, the control server 110 according to the order task hits the target inventory container is currently located on the target high shelf 1301, and at the same time determines that the target inventory container is about to be placed in the storage position of the target picking shelf 1302, attention should be paid Notably, the target picking shelf 1302 may be located under the target high shelf 1301 or under other high shelves. The storage positions for placing inventory containers on the target picking shelf 1302 may be all in an idle state, or partly in an idle state. At this time, the target inventory container may be directly placed on the target picking shelf. Based on this, the control server 110 Further determine the target access equipment 140 for accessing the target inventory container and the target handling equipment 150 for handling the target picking shelf 1302, and send an access instruction to the target access equipment 140, and send an access instruction to the target handling equipment 150 Send a move order.

After the target handling device 150 receives the handling instruction sent by the control server 110, it moves to the target picking rack 1302, and when the target access device 140 places the target inventory container on the target picking rack 1302, the target picking rack 1302 Transport to the workstation 160, and execute the corresponding order tasks.

Correspondingly, after the order task is completed at the workstation 160, the target picking rack 1302 will be transported back to the inventory area by the target handling equipment 150 or other handling equipment. Transport back to the original position of the target picking rack, or transport it to the bottom position of other high-level racks in the inventory area. If the target picking rack is transported to the bottom position of other high-position racks in the inventory area, it can be determined randomly. Preferably, the target picking rack is transported to the bottom position of other high-position racks according to the heat value of the target picking rack. The distance between the bottom position of the shelf and the workstation is positively related to the heat value of the target picking shelf. For example, the higher the heat value of the target picking shelf, the closer the distance to the workstation. Conversely, the lower the heat value of the picking shelf, the closer the distance Workstations are further apart.

It should be noted that the heat value of the picking rack in this application is determined by specifically referring to the heat value of the inventory container in the picking rack. The higher the heat value of the inventory container is, the higher the heat value of the picking rack is. The value refers to the shipment volume or shipment frequency of the goods in the inventory container. A high heat value of the inventory container means that the shipment volume of the goods in the inventory container is large or the shipment frequency is high. If multiple SKU goods are placed in the inventory container, then Determine the heat value of the inventory container based on the weighted sum of the shipments or shipment frequencies of multiple SKUs.

After the target picking rack is transported back to the inventory area, the target storage container can also be taken out from the target picking rack by the target access device 140 or other access devices 140, and put into the target high-level rack 1301 or other high-level racks.

In practical applications, the control server 110 can determine the target inventory container according to the order task according to the heat value of the inventory container. First, set the container base score for each inventory container. The position on the shelf and the distance from the workstation are determined. The lower the position on the high shelf and the closer the distance to the workstation, the higher the basic score of the container. When an order task hits an inventory container, weighted scoring is performed according to the container base score of the inventory container and the type, quantity, and sales forecast of the goods in the inventory container to obtain the corresponding inventory container score for each inventory container. The order task will first hit the inventory container with a higher score of the inventory container.

Access equipment and/or handling equipment give priority to inventory containers with higher inventory container scores, which can ensure that access equipment and/or handling equipment do fewer inventory container adjustments, reduce handling times, improve picking efficiency, and reduce the total number of items in the scene. cost.

In practical applications, the control server is further configured to determine whether the target inventory container is currently located on the target picking shelf according to the order task, and if so, determine the target handling equipment used to carry the target picking shelf, and send The target handling device sends a handling instruction;

Specifically, after the control server 110 acquires the order task, it first determines whether the target inventory container is currently located at the target picking shelf 1302 according to the order task, and if the target inventory container is just at the target picking shelf 1302 at this time, then directly determines whether the target inventory container is located at the target picking shelf 1302. The target picks the target transport device 150 of the shelf 1302 and sends a transport instruction to the target transport device 150 .

After the target transport device 150 receives the transport instruction sent by the control server 110, it moves to the target picking rack 1302, transports the target picking rack 1302 to the workstation 160, and executes the corresponding order task.

In practical applications, it is often the case that the position of the inventory container is adjusted, that is, the control server is also configured to determine the number of picks on any one of the multiple high-level racks, or any one of the multiple picking racks. The inventory container whose position is to be adjusted on the shelf, the current position of the inventory container whose position is to be adjusted, and the adjusted position, simultaneously determine the access device for adjusting the position, and send an access instruction to the access device;

The access device is further configured to take out the inventory container whose position is to be adjusted from the current position and place it in the adjusted position in response to the access instruction, and the adjusted position includes a high shelf Any one of the storage positions on the pick shelf and the storage position on the picking rack. That is, it can move from the first high-level shelf to the second high-level shelf, or from the high-level shelf to the picking shelf, or from the picking shelf to the high-level shelf, or from the first picking shelf to the second picking shelf.

In practical applications, the inventory container will also move from the high shelf to the picking shelf, or from the picking shelf to the high shelf according to the actual order task. At this time, the inventory container that needs to be adjusted is called the inventory container to be adjusted. The control server 110 will determine the current position and the adjusted position of the inventory container to be adjusted, and then send an access instruction to the access device 140 for adjusting the position, and the access device 140 will respond to the access instruction and will The repositioned inventory container is taken from the current location and placed at the relocated location. The adjusted position of the inventory container can be the storage position on the high rack or the storage position on the picking rack.

Specifically, when the current position of the inventory container is the storage position on the high shelf, the adjusted position is the storage position on the picking shelf, that is, the access device 140 takes out the inventory container to be adjusted on the high shelf and places it on the On the storage position of the picking shelf; when the current position of the inventory container is the storage position on the picking shelf, the adjusted position is the storage position on the high shelf, that is, the access device 140 will take out the inventory container to be adjusted on the picking shelf And placed on the storage position of the high shelf.

In practical applications, the control server is also configured to adjust the position of the inventory container according to the heat value of the inventory container. The higher the heat value of the inventory container, the easier it is to be picked on the picking shelf or high shelf. In the shelf, the inventory container with the higher heat value is located lower in the high-level shelf. Among different high-level shelves, the high-level shelf with the higher heat value is closer to the workstation.
