DETAILED DESCRIPTION

[0049] Embodiment 1:

[0050] This embodiment is a shelf-free storage system, such as Figure 1 As shown, it includes a material box storage unit 100, a material box picking and placing device 200, a material box 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 material box storage unit 100 is used to store material boxes, and the material boxes are directly stacked on the ground or on a bracket; the material box picking and placing device 200 has the functions of separating / stacking material boxes from stacked material box piles, automatically taking out / putting back target material boxes, material box cache and temporary storage; the material box cache unit 700 is arranged on one side of the material box storage unit 100, and a plurality of them are arranged, which has the function of temporarily storing inbound and outbound material boxes; the transfer device 800 has the function of automatically conveying the material boxes to be dispatched from the material box cache unit 700 to the outbound device 300, and also has the function of obtaining the material boxes to be inbound from the inbound device 400 and automatically conveying them to the material box storage unit 100.

[0051] 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 realize picking materials from the material boxes and transferring 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.

[0052] The warehouse management module 600 has the functions of receiving orders, analyzing orders, issuing picking tasks, managing material box storage locations, etc. It should be noted that the warehouse management module 600 is implemented using existing technology and will not be described in detail here.

[0053] like Figure 1 As shown, the material box cache unit 700 is located between the material box storage unit 100 and the picking platform 500, so that the material boxes to be shipped out or to be stored are cached on the side of the material box storage unit 100. Multiple groups of material box cache units 700 are provided to meet the needs of the material boxes to be stored in and out. In this embodiment, by adding material box cache units 700 and transfer equipment 800, the material box picking and placing equipment 200 and the transfer equipment 800 can work in parallel. Compared with the method of docking the material box picking and placing equipment 200 with the outgoing equipment 300 and the incoming equipment 400, the material box picking and placing equipment 200 only needs to put the material box into the material box cache unit 700, which reduces the working difficulty of the material box picking and placing equipment 200 and improves the operating efficiency of the entire system.

[0054] Specifically, Figure 3-Figure 6 As shown, the material box picking and placing device 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 installed 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 set as a rectangular frame structure. Temporary storage racks 204 are set on one side 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 symmetrically arranged or asymmetrically arranged.

[0055] The support body 201 is equipped with one or more telescopic fork assemblies 203, which can be specifically configured according to the requirements of picking up goods. Figure 3 and Figure 4 As shown, the telescopic fork assembly 203 can fork a single-layer material box or a multi-layer material box; when the support body 201 is equipped with two telescopic fork assemblies 203, as shown in FIG. Figure 5 and Figure 6 As shown, each telescopic fork assembly 203 can pick up single-layer or multi-layer containers.

[0056] Since the telescopic fork assembly 203 may not obtain the target material box at one time when it forks, it is necessary to temporarily place the irrelevant material boxes it has obtained on the temporary storage rack 204; even if the target material box is obtained, considering the transfer volume of the target material box, it is also necessary to temporarily place the target material box on the temporary storage rack 204. Therefore, in addition to the up and down lifting motion, the telescopic fork assembly 203 also needs to have a rotation motion to correspond to the temporary storage rack 204 on the side.

[0057] The telescopic fork assembly 203 is mounted on a support seat 206, a rotary drive mechanism is connected to the bottom of the support seat 206, and the rotary drive mechanism is connected to the lifting mechanism 205, and the rotary drive mechanism and the telescopic fork assembly 203 are driven to rise and fall simultaneously through the lifting mechanism 205. The rotary drive mechanism only needs to meet the rotation requirements, for example, the rotary drive mechanism includes a fixed seat connected to the lifting mechanism 205, and a rotation connection is formed between the fixed seat and the support seat 206, and the rotation of the support seat 206 is realized by a gear set driven by a motor, or other existing mechanisms are used to realize it.

[0058] The telescopic fork assembly 203 is a fork with a telescopic function, which can be realized through an existing structure.

[0059] In this embodiment, the transfer device 800 obtains the material box temporarily stored on the material box buffer unit 700 by lifting. Fig.11 As shown, 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 plates 702 are symmetrically arranged on both sides of the bracket 701, each group has two support plates 702, and the material boxes are stacked between the two support plates 702; the bracket 701 makes the support plates 702 form a certain installation height, so that the transfer equipment 800 can enter the bottom of the support plates 702, and the transfer equipment 800 lifts from the space between the two support plates 702 to obtain the stacked material boxes.

[0060] like Fig.12 As shown, 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.

[0061] like Figure 1 As shown, a storage-out device 300 is arranged at one end of the picking platform 500, and a storage-in device 400 is arranged at the other end. After the transfer device 800 obtains the target material box, it docks with the storage-out device 300. Fig.13As shown, the outbound equipment 300 includes a material box unpacking and stacking mechanism 302 and a conveying mechanism 301. The transfer equipment 800 moves to the material box unpacking and stacking mechanism 302, and the material box unpacking and stacking mechanism 302 unpacks the material boxes stacked on the transfer equipment 800 into single-layer material boxes, which are conveyed to the picking platform 500 by the conveying mechanism 301.

[0062] The arrangement of the storage device 400 is the same as that of the storage device 300, except that the box stacking and unstacking mechanism 302 performs the stacking operation, and the stacked boxes to be stored are lifted by the transfer device 800. The box stacking and unstacking mechanism 302 is an existing structure and will not be described in detail here.

[0063] like Fig.17 As shown, the picking station 500 includes a raw material conveying rack 501, a main conveying rack 502 and an order material box conveying rack 504 which are arranged in sequence, and the three form a U-shaped arrangement, a plurality of picking conveying racks 503 are arranged on one side of the main conveying rack 502, and the picking conveying racks 503 are located between the raw material conveying rack 501 and the order material box conveying rack 504. Each conveying rack adopts roller conveyor, which will not be described in detail here.

[0064] The working process of this embodiment is:

[0065] A. Material box outbound process:

[0066] 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.

[0067] 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 .

[0068] 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 free cache positions at the material box cache unit 700.

[0069] 4. The transfer device 800 automatically runs to the corresponding target material box cache position at the material box cache unit 700, lifts the single or stacked target material boxes and automatically transports them to the outbound device 300.

[0070] 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 is a single box, it is directly transported to the picking platform 500.

[0071] 6. The picking station 500 picks out the required items according to the order prompt information and puts them into the order material box, and the order material box is shipped out of the warehouse through the conveyor line; after the sorting is completed, the material box is transported to the warehousing equipment 400 through the conveyor line and waits for warehousing.

[0072] B. Process of returning outbound material boxes to the warehouse:

[0073] 1. After the picking is completed, the warehousing equipment 400 enters the material box stacking and unstacking mechanism 302 to stack the single material box into several stacks of material boxes; the stacked material boxes are lifted to the corresponding height position by the conveying and lifting mechanism.

[0074] 2. The storage 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.

[0075] 3. The transfer device 800 transports the material box to be stored in the material box buffer 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 in the target storage location.

[0076] 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, the material box is taken out from the material box picking and placing device 200 and restacked 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.

[0077] 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 individually, which is more efficient.

[0078] Embodiment 2:

[0079] This embodiment provides a shelf-free storage system, which differs from the first embodiment in that the transfer device 800 obtains the material box in a different way, such as Figure 2 As shown, the transfer equipment 800 adopts a side-access material box.

[0080] Specifically, Figure 14-16 As shown, the transfer device 800 includes a first mobile base 801, and a fixed or rotating fork mechanism 804 is mounted on the top of the first mobile base 801. The fork mechanism 804 includes a telescopic fork and a mounting seat 803, the telescopic forks are connected to the mounting seat 803 in pairs, and the telescopic direction of the telescopic forks is in the horizontal direction to perform side fork picking of the material box.

[0081] In this embodiment, the mounting seat 803 is a U-shaped seat for mounting a telescopic fork.

[0082] like Fig.14 As shown, 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.

[0083] The other structures are the same as those in the first embodiment and will not be described again here.

[0084] Embodiment three:

[0085] This embodiment provides a shelf-free storage system, which differs from the first and second embodiments in that the structures of the temporary storage rack 204 and the telescopic fork assembly in the material box picking and placing equipment are different.

[0086] In this embodiment, 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 mechanisms.

[0087] like Fig. 9 As shown, 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 improves the unloading efficiency; 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.

[0088] A movable stopper is also installed at the front end of the telescopic fork plate. In this embodiment, the movable stopper is a rotating claw 213. When taking a box, the rotating claw 213 rotates to the box blocking position to pull the box back. Of course, in other embodiments, the movable stopper can also be a telescopic rod. The lower telescopic fork assembly 208 takes the box by cooperating with the box support frame 212 and the movable stopper, which can prevent the box from falling and make the handling process more stable.

[0089] like Fig.10 As shown, the front section of the telescopic fork plate of the upper telescopic fork assembly 209 extends downward by a set length, that is, an extension portion 214 is added, so that the telescopic fork plate forms an L-shaped structure, and the movable limit member is moved downward by a certain distance, that is, installed on the extension portion 214, so as not to interfere when the lower fork extends out of the material receiving box.

[0090] The movable limiter of the upper telescopic fork assembly 209 is a rotating rocker 215, and its rotating power is a motor.

[0091] like Figure 7-Figure 8As shown, at least two support beams 207 are arranged on the upper surface of the temporary storage rack 204. The upper surface of the temporary storage rack 204 is a horizontal plane, that is, the support beams 207 are arranged in the horizontal plane and are perpendicular to the height direction of the support body 201. By arranging the support beams 207, the lower fork can raise the material box to a certain height when unloading the box to the temporary storage rack 204, so that the lower fork can be retracted. In this embodiment, the upper telescopic fork assembly 209 first lifts up all the target material box and the irrelevant material boxes above it, and the telescopic fork plate of the lower telescopic fork assembly 208 extends to fork the target material box.

[0092] The other structures are the same as those in the first embodiment and will not be described again here.

[0093] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
