A warehouse picking system

Abstract

The present application provides a warehouse picking system, which relates to the field of warehouse logistics technology. The warehouse picking system includes a three-dimensional storage area and a cache picking area. The three-dimensional storage area stores and retrieves boxes through a first box carrier, and transports the boxes taken out by the first box carrier to the cache picking area through a second box carrier, so that the box picking is completed through the cooperation of the first box carrier and the second box carrier. In addition, the double-depth storage position of the multi-layer box realizes high-density storage of the boxes. The warehouse picking system completes the storage and retrieval of the boxes in the three-dimensional storage area only through the first box carrier, and does not need to be matched with other additional equipment, thereby simplifying the process of box outbound and inbound storage, and improving the efficiency of box outbound and inbound storage. Since the lane width required for the first box carrier to transport the boxes is smaller than the lane width required for the existing transport equipment to transport the boxes, the storage system based on the first box carrier to transport the boxes further improves the storage density of the three-dimensional storage area.

[0040] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0041] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0042] Reference Figure 1 As shown, Figure 1 : is a structural schematic diagram of a warehouse picking system provided in an embodiment of the present application, the warehouse picking system comprises:

[0043] Three-dimensional storage area, including multi-layered bins with double-deep storage for bins;

[0044] Buffer picking area for bin picking;

[0045] A first material box carrier, used for storing and accessing material boxes in the three-dimensional storage area;

[0046] The second material box carrier is used to transport the material box taken out by the first material box carrier to the cache picking area.

[0047] In the embodiment of the present application, the three-dimensional storage area is a multi-layered material box storage area, and each layer is a material box double-deep storage position. The material box double-deep storage position means that there are two material box storage positions on each layer, and two material boxes can be placed. The design of the material box double-deep storage position improves the storage density of the three-dimensional storage area. The material box refers to a container for placing goods. The goods are stored in the three-dimensional storage area through the material box, and high-density cargo storage is achieved through the multi-layer material box double-deep storage position of the three-dimensional storage area.

[0048] Among them, the first material box carrier is a carrier with a lane width smaller than the lane width of existing handling equipment (such as CTU). The first material box carrier has ground walking and climbing functions, as well as a two-way double-depth position, that is, the first material box carrier can move in six directions: up, down, left, right, front, and back. Therefore, the first material box carrier can be responsible for the storage and retrieval of the material boxes in the three-dimensional storage area. Specifically, a lane is arranged on one side of the double-depth storage position of the material box, and the first material box carrier accesses the material boxes on both sides of the lane.

[0049] The buffer picking area is an area for picking boxes. The buffer picking area can receive boxes from the three-dimensional storage area and pick the received boxes. When a box needs to be picked, the first box carrier takes the box out of the three-dimensional storage area, and the second box carrier moves the box taken out by the first box carrier to the buffer picking area for picking.

[0050] The second container carrier has the functions of ground walking and container lifting, and has the characteristics of small size, fast running speed, large lifting stroke, etc. The second container carrier is responsible for the ground transportation of containers between the three-dimensional storage area and the cache picking area, that is, the first container carrier is used to carry the containers taken out by the first container carrier to the cache picking area.

[0051] In specific implementation, when picking the material boxes in the three-dimensional storage area, the first material box carrier climbs to the three-dimensional storage area to take out the material boxes, and moves the material boxes to the ground, and then the second material box carrier moves the material boxes taken out by the first material box carrier from the three-dimensional storage area to the buffer picking area, so as to pick the material boxes in the buffer picking area. After the picking is completed, if there are still goods in the material box, the second material box carrier can be used to move the material box from the buffer picking area to the three-dimensional storage area, and then the first material box carrier can be used to put the material box into the double-deep storage position of the material box in the three-dimensional storage area to realize the storage of the material box.

[0052] In summary, the warehouse picking system provided in the embodiment of the present application includes a three-dimensional storage area and a cache picking area. The three-dimensional storage area accesses bins through a first bin carrier, and transports the bins taken out by the first bin carrier to the cache picking area through a second bin carrier, thereby completing bin picking through the cooperation of the first bin carrier and the second bin carrier. In addition, the bin storage area includes double-depth storage locations for multi-layer bins, and the double-depth storage locations for multi-layer bins achieve high-density storage of bins. The warehouse picking system provided in the present application completes bin access in the three-dimensional storage area only through the first bin carrier, and does not require any other additional equipment, thereby simplifying the bin outbound and inbound processes and improving the bin outbound and inbound efficiency.

[0053] Since the aisle width required by the first box carrier for transporting boxes is smaller than the aisle width required by existing transport equipment for transporting boxes, the storage system based on the first box carrier for transporting boxes proposed in the present application can use part of the aisle space originally reserved for the transport equipment to transport boxes as a box storage area, thereby increasing the width of the box storage area and further improving the box storage density; since the first box carrier for transporting boxes has a climbing function and the picking and placing height is not restricted, the storage system based on the first box carrier for transporting boxes proposed in the present application can set up multi-layer box double-depth storage positions, thereby increasing the height of the box storage area and further improving the box storage density.

[0054] In an optional embodiment, the three-dimensional storage area includes:

[0055] A material box storage area and a material box buffer area; the first material box carrier is used for transporting materials between the material box storage area and the material box buffer area; the second material box carrier is used for transporting materials between the material box buffer area and the cache picking area.

[0056] In the embodiment of the present application, the material box storage area includes multiple layers of double-deep storage spaces for material boxes, which are used to store material boxes; the material box buffer area includes at least one layer of single-deep storage spaces for material boxes to be shipped out or to be shipped in. The first material box carrier is responsible for the transportation of material boxes between the material box storage area and the material box buffer area, and the second material box carrier is responsible for the transportation of material boxes between the material box buffer area and the buffer picking area, so as to realize the shipping and storage of material boxes. The setting of the material box buffer area avoids the problem of inconsistency between the shipping speed of material boxes and the picking speed of material boxes, and improves the shipping efficiency and storage efficiency of material boxes.

[0057] In specific implementation, for outbound material boxes, the first material box carrier is used to take the material boxes out of the material box storage area and transport them to the material box buffer area, and then the second material box carrier is used to transport the material boxes from the material box buffer area to the buffer picking area. For material boxes that need to be re-warehoused after picking, the second material box carrier is used to transport the picked material boxes from the buffer picking area to the material box buffer area, and then the first material box carrier is used to transport the material boxes in the material box buffer area to the material box storage area for storage, so as to achieve warehousing.

[0058] Furthermore, the three-dimensional storage area also includes a shelf storage area;

[0059] The shelf storage area is located at the bottom layer of the three-dimensional storage area and is used for storing shelves;

[0060] Shelf carrier, used for transporting shelves.

[0061] In the embodiment of the present application, a shelf storage area is deployed at the bottom layer of the shelf storage area for storing goods. The shelf refers to a container for placing large goods. For example, the shelf can be a pallet. The shelf carrier is responsible for carrying the shelves in the shelf storage area to achieve storage in units of shelves. In actual applications, small goods are stored in the storage system through material boxes, and large goods are stored in the storage system through shelves. In this way, high-density cargo storage is achieved through the material box storage area and the shelf storage area of ​​the three-dimensional storage area, and multiple types of cargo storage are supported.

[0062] Reference Figure 2 As shown, Figure 2It is a structural schematic diagram of another warehouse picking system provided by an embodiment of the present application, and the warehouse picking system includes a three-dimensional storage area, a cache picking area, a second material box carrier, a shelf carrier and a first material box carrier. Among them, the three-dimensional storage area includes a material box storage area, a material box cache area and a shelf storage area. The material box storage area is a multi-layer material box double-depth storage position, which is used to store material boxes. The first material box carrier is responsible for the material box access in the material box storage area, and storage in units of material boxes is realized. The shelf storage area is located at the bottom layer of the material box storage area, and is used to store shelves. The shelf carrier is responsible for the shelf transportation in the shelf storage area, and storage in units of shelves is realized, so that small goods can be stored by material boxes, and large goods can be stored by shelves, thereby improving storage flexibility. Since the material box storage area includes multi-layer material box double-depth storage positions, the multi-layer material box double-depth storage positions realize high-density storage of material boxes.

[0063] The material box buffer area is used to buffer material boxes to be shipped out or to be received, and the cache picking area is used for material box picking. When picking material boxes in the three-dimensional storage area, the material boxes in the material box storage area are transported to the material box buffer area by the first material box carrier, and the material boxes in the material box buffer area are transported to the cache picking area by the second material box carrier, so as to perform material picking in the cache picking area, thereby completing material box picking through the cooperation of the first material box carrier and the second material box carrier. The storage and picking system provided in the present application completes the storage and retrieval of material boxes in the three-dimensional storage area only through the first material box carrier, and does not require other additional equipment, thereby simplifying the outbound and inbound processes of material boxes and improving the outbound and outbound efficiency of material boxes. In this way, the storage and picking system realizes high-density storage and storage of various types of goods through the three-dimensional storage area, and quickly realizes material sorting through the cooperation of the second material box carrier and the first material box carrier.

[0064] In an optional embodiment, the cache picking area includes:

[0065] The material picking station is used to park the second material box carrier so as to pick the material boxes transported by the second material box carrier.

[0066] In the embodiment of the present application, the second container carrier transports the container from the three-dimensional storage area to the buffer picking area, and the second container carrier carrying the container is parked at the material picking station. After the second container carrier is parked, the container transported by the second container carrier is directly picked at the material picking station.

[0067] Furthermore, the second material box carrier has a lifting component, and after entering the material picking station, the transported material box is lifted to a target height, and the target height is determined according to the ergonomic working height. Thus, the operator can pick the goods from the material box transported by the second material box carrier at the material picking station, and after completing the material picking, the lifting component is retracted by the second material box carrier to transport the material box away.

[0068] In an optional embodiment, the cache picking area further includes:

[0069] The conveyor line is used to convey empty bins or bins loaded with picked materials, wherein the empty bins are used to place materials picked out from the bins.

[0070] In the embodiment of the present application, an empty material box or a material box loaded with selected materials is transported by a conveyor line, that is, when material picking is performed, an empty material box is transported to a material picking station by a conveyor line, and an operator places the selected materials in an empty material box on the conveyor line, and after the picking is completed, the material box loaded with the selected materials is transported away by the conveyor line. In this way, the selected material box is transferred to a subsequent process by a conveyor line.

[0071] In an optional embodiment, the cache picking area further includes:

[0072] A first release control device, used for releasing the second material box carrier parked in the material picking station;

[0073] The second release control device is used to release the material box loaded with the selected materials on the conveyor line.

[0074] In the embodiment of the present application, the first release control device and the second release control device may be release control buttons. After the material box carried by the second material box carrier in the material picking station is picked, the first release control device may be used to release the second material box carrier to leave. For example, if the material box carried by the second material box carrier is loaded with goods A, after the operator picks the goods A out of the material box, the first release control device may be used to release the second material box carrier to leave. Moreover, after the picking is completed, the material box loaded with the picked materials on the conveyor line is released to leave by the second release control device. For example, when a certain order requires goods A, goods B, and goods C, after these three kinds of goods are picked into the material box on the conveyor line, the second release control device may be used to release the material box loaded with goods A, goods B, and goods C to leave.

[0075] In an optional embodiment, the cache picking area further includes:

[0076] Picking racks are used to place empty bins or bins loaded with picked materials.

[0077] In an embodiment of the present application, the picking shelves in the cache picking area include one or two. The picking shelves can be placed on multiple material boxes. Specifically, empty material boxes or material boxes loaded with picking materials are placed on the picking shelves. When picking the material boxes transported by the second material box carrier, the empty material boxes are placed on the picking shelves, and the operator places the picked materials in the empty material boxes on the picking shelves; after the picking is completed, the material boxes loaded with picking materials placed on the picking shelves can be directly transported away, or after all the material boxes on the picking shelves are placed with picking materials, the entire picking shelf can be directly transported away.

[0078] In an optional embodiment, the cache picking area further includes:

[0079] A first release control device, used for releasing the second material box carrier parked in the material picking station;

[0080] The third release control device is used to release the picking shelf.

[0081] In the embodiment of the present application, the first release control device and the third release control device may be release control buttons. After the material box carried by the second material box carrier in the material picking station is picked, the first release control device may be used to release the second material box carrier to leave. For example, if the material box carried by the second material box carrier is loaded with goods A, after the operator picks the goods A out of the material box, the first release control device may be used to release the second material box carrier to leave. In addition, the picking shelf is used to place the material box loaded with the picking materials. After all the material boxes on the picking shelf are placed with the picking materials, the picking shelf is released by the third release control device. For example, if the picking shelf can hold 6 material boxes, when all the 6 material boxes on the picking shelf are placed with the picking materials, the picking shelf can be directly released by the third release control device.

[0082] Furthermore, the cache picking area also includes:

[0083] Shelf carriers are used to transport and release picking shelves.

[0084] In the embodiment of the present application, the picking rack is released by transporting the rack carrier, the rack carrier has the function of walking on the ground, and has the characteristics of large load weight and light volume.

[0085] The structures of the two cache picking areas are described below with reference to the accompanying drawings.

[0086] Reference Figure 3 As shown, Figure 3 1 is a schematic diagram of a three-dimensional structure of a cache picking area provided in an embodiment of the present application. Specifically, the cache picking area includes:

[0087] A material picking station, used for parking the second material box carrier to pick the material box carried by the second material box carrier;

[0088] A conveyor line is used to convey an empty material box or a material box loaded with picked materials, wherein the empty material box is used to place the materials picked from the material box;

[0089] A first release control device, used for releasing the second material box carrier parked in the material picking station;

[0090] The second release control device is used to release the material box loaded with the selected materials on the conveyor line.

[0091] In the embodiment of the present application, the picking material box is transferred to the subsequent process through the conveyor line. The second material box carrier moves the material box from the three-dimensional storage area to the cache picking area, and enters the material picking station in sequence according to the order sequence; the second material box carrier has a lifting component, and after entering the material picking station, it lifts the transported material box to the target height that is ergonomically comfortable. The empty material box placed after picking the material is transmitted through the conveyor line, and enters the material picking station according to the task situation, and the remaining material boxes wait on the conveyor line. After the operator picks the materials required for the order from the material box, and places the picked materials in the empty material box transported by the conveyor line, after the operator completes the picking, the first release control device releases the second material box carrier parked in the material picking station, and the second release control device releases the material box loaded with the picked materials on the conveyor line. In this way, the material picking and the transfer of the material box after picking are completed.

[0092] Reference Figure 4 As shown, Figure 4 1 is a schematic diagram of a three-dimensional structure of another cache picking area provided in an embodiment of the present application. Specifically, the cache picking area includes:

[0095] A first release control device, used for releasing the second material box carrier parked in the material picking station;

[0096] The third release control device is used to release the picking shelf.

[0097] In an embodiment of the present application, the picking bins are transferred to subsequent processes through picking shelves. The picking shelves are located on both sides of the material picking station, and each picking shelf can hold multiple bins. The second bin carrier transports the bins from the three-dimensional storage area to the cache picking area, and enters the material picking station in sequence according to the order sequence; the second bin carrier has a lifting component, and after entering the material picking station, it lifts the transported bins to an ergonomically comfortable target height. The materials picked by the operator are placed in the bins on the picking shelves on both sides. After the operator completes the picking, the second bin carrier parked in the material picking station is released by the first release control device, and the picking shelves are released by the third release control device. In actual applications, the picking shelves can be transported manually or by shelf carriers. Thus, the material picking and the transfer of the bins after picking are completed.

Specifically, the storage picking system includes a three-dimensional storage area, a buffer picking area, a second bin carrier, a first bin carrier and a shelf carrier.

[0099] The three-dimensional storage area includes a material box storage area, a material box buffer area and a shelf storage area. The material box storage area is a multi-layer material box double-depth storage area for storing material boxes. The first material box carrier is responsible for the material box access in the material box storage area, realizing storage in units of material boxes. The shelf storage area is located at the bottom layer of the material box storage area and is used to store shelves. The shelf carrier is responsible for the shelf transportation in the shelf storage area, realizing storage in units of shelves, so that small goods can be stored by material boxes and large goods can be stored by shelves, thereby improving storage flexibility. Since the material box storage area includes multi-layer material box double-depth storage areas, the multi-layer material box double-depth storage areas realize high-density storage of material boxes.

[0100] The material box buffer area is used to buffer material boxes to be shipped out or to be received in, and the cache picking area is used for material box picking. The cache picking area transfers the picked material boxes to the subsequent process through the conveyor line. When picking the material boxes, the material boxes in the material box storage area are accessed by the first material box carrier, and the material boxes taken out by the first material box carrier are transported to the cache picking area by the second material box carrier, so that the material box picking is completed by the cooperation of the first material box carrier and the second material box carrier. The storage and picking system provided by the present application completes the storage and access of material boxes in the three-dimensional storage area only by the first material box carrier, and does not require other additional equipment, thereby simplifying the material box outbound and inbound processes and improving the outbound and outbound efficiency of the material boxes.
