[0052] The present embodiment provides a shelf-free warehousing system, as shown in Figure 1, including a bin storage unit 100, a bin picking and placing device 200, a bin cache unit 700, a transfer device 800, an outbound device 300, a picking platform 500, an inbound device 400 and a warehouse management module 600. The bin storage unit 100 is configured to store bins, and the bins are stacked directly on the ground or on a bracket; the bin picking and placing device 200 has the functions of separating / stacking bins from stacked bin piles, automatically taking out / putting back target bins, caching bins and temporarily storing them; the bin cache unit 700 is arranged on one side of the bin storage unit 100, and a plurality of them are provided, which has the function of temporarily storing inbound and outbound bins; the transfer device 800 has the function of automatically conveying the bins to be outbound from the bin cache unit 700 to the outbound device 300, and also has the function of automatically conveying the bins to be inbound obtained from the inbound device 400 to the bin storage unit 100.

[0053] The outbound equipment 300 is docked with the transfer equipment 800, and has the functions of automatically taking material boxes from the transfer equipment 800, automatically destacking the stacked target material boxes, and transporting the single-layer target material boxes to the picking platform 500; the picking platform 500 can pick materials from the material boxes and transfer the order material boxes; the inbound equipment 400 is docked with the transfer equipment 800, and can realize the automatic transfer of single or multiple material boxes to the transfer equipment 800, and has the function of stacking material boxes and transporting the stacked material boxes to be stored from the picking platform 500 to the transfer equipment 800.

[0054] The warehouse management module 600 has functions such as receiving orders, analyzing orders, issuing picking tasks, and managing material box storage locations. It should be noted that the warehouse management module 600 is implemented using existing technology and will not be described in detail here.

[0055] As shown in Figure 1, the bin cache unit 700 is located between the bin storage unit 100 and the picking platform 500, so that the bins to be shipped out or the bins to be received can be cached on the side of the bin storage unit 100. Multiple groups of bin cache units 700 are provided to meet the needs of bins to be shipped in and out. In this embodiment, by adding the bin cache unit 700 and the transfer equipment 800, the bin picking and placing device 200 and the transfer equipment 800 can work in parallel. Compared with the method of docking the bin picking and placing device 200 with the outbound device 300 and the inbound device 400, the bin picking and placing device 200 only needs to place the bin into the bin cache unit 700, which reduces the working difficulty of the bin picking and placing device 200 and improves the operating efficiency of the entire system.

[0056] As shown in Figures 3-6, the material box picking and placing equipment 200 includes a support body 201, a temporary storage rack 204, a telescopic fork assembly 203, a second mobile base 202, etc. The support body 201 is fixedly mounted on the top of the second mobile base 202. In order to facilitate the transfer of the forked material box to the temporary storage rack 204, the support body 201 is configured as a rectangular frame structure. Temporary storage racks 204 are set on one or both sides of the support body 201. Multiple temporary storage racks 204 are installed at intervals along the height direction of the support body 201. Each temporary storage rack 204 can store single-layer or multi-layer material boxes. When temporary storage racks 204 are installed on both sides of the support body 201, the temporary storage racks 204 on both sides can be arranged symmetrically or asymmetrically.

[0057] The support body 201 is equipped with one or more telescopic fork assemblies 203, which can be configured based on the specific requirements for picking up goods. When the support body 201 is equipped with one telescopic fork assembly 203, as shown in Figures 3 and 4, the telescopic fork assembly 203 can pick up single-layer or multi-layer containers. When the support body 201 is equipped with two telescopic fork assemblies 203, as shown in Figures 5 and 6, each telescopic fork assembly 203 can pick up single-layer or multi-layer containers.

[0058] Because the telescopic fork assembly 203 may not always reach the target bin during a single fork lift, it is necessary to temporarily place any unrelated bins it has reached on the temporary storage rack 204. Even if it reaches the target bin, it must be temporarily placed on the temporary storage rack 204 to accommodate the required transfer volume. Therefore, in addition to vertical movement, the telescopic fork assembly 203 must also be capable of rotation to accommodate the side temporary storage racks 204.

[0059] Telescopic fork assembly 203 is mounted on support base 206. A rotary drive mechanism is connected to the bottom of support base 206, which is in turn connected to lifting mechanism 205. Lifting mechanism 205 drives both the rotary drive mechanism and telescopic fork assembly 203 to rise and fall simultaneously. The rotary drive mechanism can be any mechanism that meets the rotation requirements. For example, the rotary drive mechanism may include a fixed base connected to lifting mechanism 205, with a rotational connection between the fixed base and support base 206. Rotation of support base 206 may be achieved through a motor-driven gear train, or other existing mechanisms may be employed.

[0060] The telescopic fork assembly 203 is a fork with a telescopic function, which can be realized by an existing structure.

[0061] In this embodiment, the transfer equipment 800 obtains the material boxes temporarily stored on the material box cache unit 700 in a jacking manner. As shown in Figure 11, in order to cooperate with the picking method of the transfer equipment 800, the material box cache unit 700 includes a bracket 701, and multiple groups of support plate assemblies are arranged on both sides of the bracket 701. Each group of support plate assemblies has two support plates 702, and the two support plates 702 of each group are configured to support stacked material boxes, that is, the material boxes are stacked between the two support plates 702; wherein, multiple groups of support plate assemblies are symmetrically arranged on both sides of the bracket 701, and each group has two support plates 702; the bracket 701 makes the support plates 702 form a certain installation height for the transfer equipment 800 to enter the bottom of the support plates 702, and the transfer equipment 800 jacks up from the space between the two support plates 702 to obtain the stacked material boxes.

[0062] As shown in Figure 12, the transfer equipment 800 includes a first movable base 801 and a lifting mechanism 802. The lifting mechanism 802 is installed on the top of the first movable base 801. It only needs to lift and support the material box. For example, the lifting mechanism 802 includes a telescopic rod and a support plate connected to the top of the telescopic rod.

[0063] As shown in Figure 1, an outbound device 300 is set at one end of the picking platform 500, and an inbound device 400 is set at the other end. After the transfer equipment 800 takes the target material box, it docks with the outbound device 300. As shown in Figure 13, the outbound device 300 includes a material box unstacking mechanism 302 and a conveying mechanism 301. The transfer equipment 800 moves to the material box unstacking mechanism 302, and the material box unstacking mechanism 302 disassembles the material boxes stacked on the transfer equipment 800 into single-layer material boxes, which are then conveyed to the picking platform 500 by the conveying mechanism 301.

[0064] The arrangement of the storage device 400 is the same as that of the outbound device 300, except that the stacking operation is performed by the box unpacking and stacking mechanism 302, and the stacked boxes to be stored are lifted by the transfer device 800. The box unpacking and stacking mechanism 302 is an existing structure and will not be described in detail here.

[0065] As shown in FIG17 , the picking station 500 includes a raw material conveyor rack 501, a main conveyor rack 502, and an order bin conveyor rack 504, which are arranged in sequence and form a U-shape. Multiple picking conveyor racks 503 are provided on one side of the main conveyor rack 502, and the picking conveyor racks 503 are located between the raw material conveyor rack 501 and the order bin conveyor rack 504. Each conveyor rack utilizes roller conveyors, which will not be described in detail here.

[0066] It should be understood that, as shown in FIG2 , in another embodiment, the transfer equipment 800 adopts a side-picking method for the material box. Referring to FIG14 to FIG16 , the transfer equipment 800 includes a first mobile base 801, and a forking mechanism 804 is fixed or rotated on the top of the first mobile base 801. The forking mechanism 804 includes a telescopic fork and a mounting seat 803, and the telescopic fork is connected to the mounting seat 803 in pairs, and the telescopic direction of the telescopic fork is along the horizontal direction to perform side forking of the material box. Optionally, the mounting seat 803 is a U-shaped seat to facilitate the installation of the telescopic fork. As shown in FIG14 , the material box cache unit 700 includes a support frame 703, and the support frame 703 only needs to meet the support requirements for the material box.

[0067] In yet another embodiment, another structural implementation of the temporary storage rack 204 and the telescopic fork assembly in the material box picking and placing device is provided.

[0068] Among them, an upper telescopic fork assembly 209 and a lower telescopic fork assembly 208 are provided. The upper telescopic fork assembly 209 and the lower telescopic fork assembly 208 respectively include two oppositely arranged telescopic fork plates, and the telescopic fork plates can be driven to extend and retract by a chain transmission mechanism or other mechanism.

[0069] As shown in Figure 9, the two telescopic fork plates of the lower telescopic fork assembly 208 are connected near the rear position by a box pushing rack 211. When unloading the box, the box pushing rack 211 pushes the material box from the rear, which makes the unloading efficiency higher; the box supporting rack 212 is installed on the lower side of the telescopic fork plate, and the box supporting rack 212 can support the two sides of the bottom of the material box when taking the box.

[0070] The front end of the telescopic fork plate is also equipped with a travel stop. In this embodiment, the travel stop is a rotating claw 213. When removing a box, the rotating claw 213 rotates to a position to block the box, pulling the box back. Of course, in other embodiments, the travel stop can also be a telescopic rod. The lower telescopic fork assembly 208, through the box support frame 212 and the travel stop, can remove the box, preventing the box from falling and ensuring a more stable handling process.

[0071] As shown in FIG10 , the front section of the telescopic fork plate of the upper telescopic fork assembly 209 is extended downward by a set length, i.e., an extension portion 214 is added, so that the telescopic fork plate forms an L-shaped structure, and the movable limiter is moved downward by a certain distance, i.e., installed on the extension portion 214, so as not to interfere when the lower fork extends out of the material receiving box.

[0072] The movement limiter of the upper telescopic fork assembly 209 adopts a rotating rocker 215, and its rotation power is a motor.

[0073] As shown in Figures 7-8, at least two support beams 207 are provided on the upper surface of the temporary storage rack 204. The upper surface of the temporary storage rack 204 is horizontal, i.e., the support beams 207 are arranged within the horizontal plane and perpendicular to the height of the support body 201. The support beams 207 allow the lower forks to elevate the containers to a certain height when unloading containers onto the temporary storage rack 204, allowing the lower forks to retract. In this embodiment, the upper telescopic fork assembly 209 first lifts the target container and all unrelated containers above it, and then the telescopic fork plates of the lower telescopic fork assembly 208 extend to pick up the target container.

[0074] The working process of this embodiment is:

[0075] A. Material box outbound process:

[0076] 1. The warehouse management module 600 obtains detailed order information, converts the order information into system instructions, and transmits them to the material box picking and placing device 200, the outbound device 300, the inbound device 400, the picking platform 500 and the transfer device 800.

[0077] 2. The material box picking and placing device 200 enters the material box storage unit 100, takes out the material box to be shipped (target material box) from the corresponding position according to the instruction issued by the warehouse management module 600, and stacks and caches it on the material box picking and placing device 200.

[0078] 3. The material box picking and placing device 200 runs to the material box cache unit 700, places the target material box it carries on the material box cache unit 700, and automatically plans the unloading position and the number of stacking layers according to the number of material boxes and the idle cache positions in the material box cache unit 700.

[0079] 4. The transfer device 800 automatically moves to the corresponding target material box cache position at the material box cache unit 700, picks up the single or stacked target material boxes and automatically transports them to the outbound device 300.

[0080] 5. The outbound device 300 automatically docks with the transfer device 800, disassembles the stacked target boxes into single boxes, and transports them to the picking platform 500 through the conveying mechanism 301; if the outbound box is a single box, it is directly transported to the picking platform 500.

[0081] 6. The picking station 500 picks the required items according to the order prompt information and puts them into the order material box, which is then shipped out of the warehouse via the conveyor line. After sorting, the material box is transported to the warehousing equipment 400 via the conveyor line and waits for storage.

[0082] B. Process of returning outbound material boxes to the warehouse:

[0083] 1. After completing the picking, the warehousing equipment 400 enters the bin unpacking and stacking mechanism 302 to stack the single bins into several stacks. The stacked bins are lifted to the corresponding height position by the conveying and lifting mechanism.

[0084] 2. The warehousing device 400 and the transfer device 800 are automatically docked, and the material boxes to be stored are automatically transferred to the transfer device 800.

[0085] 3. The transfer device 800 transports the material box to be stored to the material box cache unit 700 for temporary storage, and then waits for the material box picking and placing device 200 to transport the material box to be stored to the target storage location.

[0086] 4. According to the instructions of the warehouse management module 600, the material box picking and placing device 200 clamps the material box to be stored in the material box cache unit 700 and places the material box on the temporary storage rack 204 of the material box picking and placing device 200 through the lifting mechanism, rotating mechanism, etc. After the material box picking and placing device 200 carries the material box to be stored to the target storage position of the material box storage unit 100, it takes the material box out of the material box picking and placing device 200 and restacks it to the corresponding position of the material box storage unit 100; the system can optimize the position of the material box at any time according to order requirements.

[0087] This embodiment provides a material box cache unit 700 for incoming and outgoing material boxes and configures a transfer device 800 to transport the incoming and outgoing material boxes separately, thereby achieving higher efficiency.

[0088] The foregoing description is merely a preferred embodiment of the present application and is not intended to limit the present application. Persons skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
