DETAILED DESCRIPTION

[0068] To make objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in combination with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are a part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by a person of ordinary skill in the art without creative work shall fall within the protection scope of this application.

[0069] First, a person skilled in the art should understand that the implementations are merely used for explaining the technical principles of this application, and are not intended to limit the protection scope of this application. A person skilled in the art may adjust the implementations as required, to adapt to a specific application scenario.

[0070] In addition, it should be noted that, in the description of this application, terms such as upper, lower, left, right, front, rear, inner, and outer that indicate directions or position relationships are based on the directions or position relationships shown in the accompanying drawings. This is merely for ease of description, and does not indicate or imply that an apparatus or component needs to have a particular orientation, and is constructed and operated in a particular orientation. Therefore, this should not be understood as a limitation to this application.

[0071] In the description of this specification, the description with reference to terms such as an embodiment, some embodiments, an illustrative embodiment, an example, a specific example, or some examples means that specific features, structures, materials, or characteristics described in combination with the embodiments or examples are included in at least one embodiment or example of the present disclosure. In this specification, the foregoing example expressions of the terms are not necessarily with respect to a same embodiment or example. In addition, the described specific features, structures, materials, or characteristics may be combined in a proper manner in any one or more of embodiments or examples.

[0072] Various types of robots are widely applied to various fields such as industry and life, and the robots play important roles in industries such as transportation and logistics. In a warehousing and logistics system, goods are usually stored by using shelving units, and the robot may pick or place the goods and transport the goods by docking with a shelving unit or a conveyor. One or more totes may be stored in each storage location on the shelving unit. Goods are stored by using the totes, and in a storage location with a depth for storing a plurality of totes, the plurality of totes are independent of each other. When a tote is picked or placed, a tote at the entrance needs to be first removed, and other totes in the storage location are picked or placed. In addition, because the robot that picks or places the goods needs to reach the interior of the storage location to pick or place the tote, space needs to be reserved in the storage location for the robot to perform operations.

[0073] However, currently, when totes are stored deep on the shelving unit, the totes are independent of each other, and space for picking or placing needs to be reserved, so that when the robot picks or places the goods, a fork of the robot may reach the interior of a storage location of the shelving unit to pick or place the tote deep in the storage location, resulting in a low storage density of the shelving unit.

[0074] In view of the foregoing problem, the embodiments of this application provide a tote, a shelving unit, and a warehousing system. The totes may be hooked to each other, so that when a tote is picked or placed, a plurality of totes may be pulled or pushed to be moved. In addition, the totes may be detachably connected to each other, and the robot does not need to reach deep into the storage location to pick or place the tote. In this way, a space design of the shelving unit may be more compact, thereby improving space utilization and a warehousing density.

[0075] For ease of understanding, first, application scenarios of the tote, the shelving unit, and the warehousing system provided in the embodiments of this application are described.

[0076] The tote provided in the embodiments may be stored on a shelving unit, and the shelving unit is arranged in a warehousing system. The warehousing system may be applied to product storage in an industrial production line, inbound and outbound of inventory products in a manufacturing industry, and inbound and outbound of retail products, and may also be applied to different fields of e-commerce logistics, such as express delivery inbound and outbound and sorting. In addition, products or goods that can be stored in the tote may be industrial components, electronic accessories or products, medicines, clothing accessories, foods, books, and the like. This is not specifically limited in the embodiments of this application.

[0077] FIG. 1 is a first schematic diagram of a structure of a tote according to an embodiment of this application. FIG. 2 is a second schematic diagram of a structure of a tote according to an embodiment of this application. FIG. 3 is a first cross-sectional view of a tote according to an embodiment of this application. FIG. 4 is a schematic diagram of totes hooked to each other according to an embodiment of this application.

[0078] As shown in FIG. 1 to FIG. 4, an embodiment of this application provides a tote 10. The tote 10 has an accommodation cavity 190 for storing goods. The tote 10 may be stored on a shelving unit of a warehousing system, and a plurality of totes 10 may be stored on the shelving unit. The plurality of totes 10 may be detachably connected to each other. When a target tote 10 is picked or placed, the plurality of totes 10 connected to each other may be dragged to synchronously move, and after the target tote 10 is removed from the shelving unit, the target tote 10 may be separated from other totes 10, to complete a goods pick-up operation.

[0079] It can be understood that, a storage location of the shelving unit for storing the tote 10 has a depth, that is, the plurality of totes 10 connected to each other are sequentially connected and arranged from the entrance of the storage location to the interior of the storage location. Therefore, in a case that a tote 10 at the entrance of the storage location is taken out, when the tote 10 at the entrance of the storage location is moved out of the storage location, another tote 10 adjacent to and connected to the tote 10 is moved to the entrance of the storage location. In this way, it can be ensured that after each goods pick-up, the totes 10 in the storage location are always arranged from the entrance to the interior of the storage location, that is, it can be ensured that the tote 10 can be taken out from the entrance of the storage location without reaching the interior of the storage location. Correspondingly, when a tote 10 is placed into the storage location of the shelving unit, the existing totes 10 in the storage location may be pushed to synchronously move towards the interior of the storage location, so that the tote 10 that is just placed into the storage location is located at the entrance of the storage location.

[0080] In some embodiments, the tote 10 includes a tote body 100, a first connecting member 200, and a second connecting member 300. The first connecting member 200 is arranged at the bottom of at least one side wall 104 of the tote body 100, and the second connecting member 300 is arranged at the bottom of at least one side wall 104 of the tote body 100. The first connecting member 200 and the second connecting member 300 may be arranged on a same side or different sides of the tote body 100. For example, the first connecting member 200 and the second connecting member 300 may be respectively arranged at two ends in a length direction of the tote body 100. In this way, when two totes 10 are adjacently connected and arranged, a first connecting member 200 of one tote 10 may be connected to a second connecting member 300 of the other tote 10, and when one tote 10 is dragged to move, the other tote 10 also synchronously moves.

[0081] The first connecting member 200 and the side wall 104 of the tote body 100 enclose at least one groove portion 201, and the second connecting member 300 has at least one hooking portion 301. The plurality of totes 10 may be sequentially connected, and a hooking portion 301 of a tote 10 is hooked to a groove portion 201 of an adjacent tote 10. When the plurality of totes 10 are hooked to each other, the plurality of totes 10 may be sequentially arranged in a straight line direction, and when a tote 10 located at an end of the arrangement receives a pulling force or a pushing force in the arrangement direction, all the hooked totes 10 are driven to move together.

[0082] It can be understood that, when a target tote 10 needs to be separated from another tote 10, the tote 10 may be separated from the another adjacent tote 10 only by lifting the corresponding target tote 10, that is, a first connecting member 200 and a second connecting member 300 of the two totes 10 are released from being hooked.

[0083] When a target tote 10 needs to be hooked to another tote 10 from a separated state, the two totes 10 may be first abutted, and then the target tote 10 may be lowered, so that a first connecting member 200 and a second connecting member 300 of the two totes 10 are docked to each other, and further, the two totes 10 are hooked to each other.

[0084] It should be noted that, when the plurality of totes 10 provided in this embodiment of this application are simultaneously stored in a storage location, adjacent totes 10 may be hooked to each other. When a tote 10 is picked or placed, the plurality of sequentially connected totes 10 may be dragged to move simultaneously, thereby improving space utilization and a storage density of the shelving unit.

[0085] In addition, the top of the tote 10 is set open, to facilitate placing or taking out goods. However, both the first connecting member 200 and the second connecting member 300 are arranged at the bottom position of the tote 10. In this way, when the plurality of totes 10 are dragged to move simultaneously, a structure in which the first connecting member 200 and the second connecting member 300 are hooked to each other has a stronger load bearing capability, and the tote 10 is not easily deformed.

[0086] In this embodiment of this application, when the plurality of totes 10 are sequentially arranged and hooked to each other, a quantity of the totes 10 may be two, three, four, five, or more. This is not specifically limited in this embodiment of this application.

[0087] Still referring to FIG. 1 to FIG. 4, in some embodiments, a notch of the groove portion 201 faces the top of the tote body 100, and the hooking portion 301 faces the bottom of the tote body 100, so that two adjacent totes 10 may be connected or separated in a lifting and lowering manner, thereby improving convenience of a goods pick-up operation.

[0088] It can be understood that, when stored in a storage location of the shelving unit, the plurality of totes 10 may be arranged in a horizontal direction, and when the target tote 10 is separated from another adjacent tote 10, a hooking portion 301 of the target tote 10 may be separated from a groove portion 201 of the another tote 10 only by lifting the target tote 10 in a direction perpendicular to the direction in which the plurality of totes 10 are arranged, so that the two totes 10 are separated from each other.

[0089] Correspondingly, when the target tote 10 is hooked to another tote 10, after the two totes 10 are abutted, the hooking portion 301 of the target tote 10 may be hooked to the another tote 10 only by lowering the target tote 10 in a direction perpendicular to the direction in which the plurality of totes 10 are arranged, so that the two totes 10 are connected together. In this way, when the tote 10 is picked or placed, a structure of the shelving unit for storing the tote 10 is not interfered or disturbed, thereby improving convenience of picking and placing operations.

[0090] Specific structures of the first connecting member 200 and the second connecting member 300 with the tote body 100 and specific connection manners of the first connecting member 200 and the second connecting member 300 with the tote body 100 are described in detail below.

[0091] FIG. 5 is a first schematic diagram of connection of a first connecting member in a tote according to an embodiment of this application, and FIG. 6 is a cross-sectional view of a position of a first connecting member in a tote according to an embodiment of this application.

[0092] Referring to FIG. 5 and FIG. 6, with reference to FIG. 1 and FIG. 2, in some embodiments, the first connecting member 200 and the tote body 100 may be integrally formed, to improve manufacturing convenience of the tote 10 and reduce product costs.

[0093] For example, the tote body 100 may be of a plastic material. The first connecting member 200 may be integrally injection-molded during production and manufacturing of the tote body 100, and the groove portion 201 is formed during integral injection molding. In addition, the side wall of the first connecting member 200 may be provided with a stiffener, to improve structural strength of the first connecting member 200.

[0095] Referring to FIG. 7, in some embodiments, the second connecting member 300 and the tote body 100 may be integrally formed, to improve manufacturing convenience of the tote 10 and reduce product costs.

[0096] For example, the tote body 100 may be of a plastic material. The second connecting member 300 may be integrally injection-molded during production and manufacturing of the tote body 100, and the hooking portion 301 is formed during integral injection molding. A stiffener may be provided between the second connecting member 300 and the tote body 100, to improve structural strength of the second connecting member 300, and further improve a load bearing capability of the hooking portion 301. Alternatively, the tote body 100 may be of a plastic material, and the second connecting member 300 may be of a metal material. The second connecting member 300 forms the hooking portion 301, and during injection molding of the tote body 100, a part of the structure of the second connecting member 300 is encapsulated in the tote body 100, so that the second connecting member 300 and the tote body 100 become a whole.

[0097] It should be noted that, in addition to a case in which the first connecting member 200 and the second connecting member 300 may be connected to the tote body 100 in an integrally formed manner, both the first connecting member 200 and the second connecting member 300 may be connected to the tote body 100 in a detachable manner. During specific implementation, either of the first connecting member 200 and the second connecting member 300 may be connected in the integrally formed manner and the detachable manner. This is not specifically limited in this embodiment of this application.

[0098] The detachable connection manner between the first connecting member 200 and the tote body 100 is described in detail below.
