[0041] The following description of exemplary embodiments of the present invention is made in conjunction with the accompanying drawings, in which various details of the embodiments of the present invention are included to facilitate understanding. These details should be considered as merely exemplary. Therefore, it should be appreciated by those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0042] Figure 1 2 is a schematic structural diagram of a warehousing and outbound system according to an embodiment of the present invention. Figure 2 Schematic diagram of the connection between a pallet and a chain transmission assembly of a warehousing and unloading system according to an embodiment of the present invention. Figure 3 This is a schematic diagram of the structure of the tray of the embodiment of the present invention, refer to Figure 1 、 Figure 2 and Figure 3 , the warehousing and outbound system includes:

[0043] A hollow shelf 11, wherein the shelf 11 includes a transmission component 12 and a fixing component 13;

[0044] a tray 16 on which a first connecting component 17 and a second connecting component 18 are provided;

[0045] In which, the first connecting component 17 is used to connect with the transmission component 12 so that the pallet 16 rises or falls along the shelf 11 under the drive of the transmission component 12; when the pallet 16 rises to a specific position, the second connecting component 18 is connected with the fixing component 13 to fix the pallet 16 at the specific position.

[0046] In the warehousing and outbound system of this embodiment, when entering the warehouse, the first connecting component 17 on the pallet 16 is connected to the transmission component 12, and is driven by the transmission component 12 to rise to a specific position along the shelf 11; when reaching the specific position, the second connecting component 18 on the pallet is connected to the fixing component 13 to fix the pallet 16 at the specific position and store the pallet 16 at the specific position. At this time, the first connecting component 17 can be connected to the transmission component or disconnected from the transmission component; when leaving the warehouse, the second connecting component 18 of the pallet 16 is disconnected from the fixing component and is driven by the transmission component 12 to descend to the bottom along the shelf 11 for leaving the warehouse.

[0047] In an optional embodiment, the transmission assembly 12 is a chain transmission assembly, and the transmission direction is perpendicular to the horizontal plane; a double-ear type hanging hole 15 is provided on the transmission assembly 12 and the fixing assembly 13;

[0048] The first connecting assembly 17 and the second connecting assembly 18 respectively include a retractable connecting rod 19 ; when the connecting rod 19 is extended, the connecting rod 19 passes through the hanging hole 15 so that the tray 16 is hung on the transmission assembly 12 or the fixing assembly 13 .

[0049] Specifically, the transmission assembly 12 and the fixing assembly 13 each include two independent chains 14, and the two independent chains 14 are located on opposite surfaces. As an example, the two independent chains included in the transmission assembly 12 are respectively located on the left side and the right side of the shelf 11, and the two independent chains included in the fixing assembly 13 are respectively located on the front side and the rear side of the shelf 11. As a more preferred embodiment, Figure 1 As shown, the chain included in the transmission assembly 12 is installed on the frame body in the diagonal direction of the shelf 11, and the chain included in the fixing assembly 13 is installed on the frame body in the other diagonal direction of the shelf 11. By installing the chains of the transmission assembly 12 and the fixing assembly 13 on the frames located on the diagonal direction respectively, it can ensure that the pallet rises or falls along the shelf more smoothly.

[0050] like Figure 1 As shown, the transmission assembly 12 and the fixing assembly 13 further include a gear 20 , and the gear 20 is arranged at the top corner of the shelf 11 , and the chain 14 is wrapped around the gear 20 opposite to each other above and below.

[0051] In an optional embodiment, the hanging holes 15 can be arranged at equal intervals, and their intervals can be set according to the height of the goods. When each shelf is only used to store one kind of goods, arranging the hanging holes at equal intervals can maximize space utilization.

[0052] The warehousing system also includes a pallet 16 for carrying goods. A first connecting component 17 and a second connecting component 18 are provided on the pallet 16, and the first connecting component 17 and the second connecting component 18 respectively include a retractable connecting rod 19. Since the first chain transmission 11 and the fixing component 13 respectively include two independent chains, correspondingly, the first connecting component 17 and the second connecting component 18 respectively include two groups of retractable connecting rods 19. Each two independent chains 14 are located on opposite surfaces, and correspondingly, the two groups of retractable connecting rods 19 extend in opposite directions. If the two independent chains included in the transmission component 12 are respectively located on the left and right sides of the shelf, the two groups of connecting rods of the first connecting component, when extended, extend toward the left and right sides of the shelf respectively. As a preferred embodiment, as Figure 1 and Figure 2 As shown, the first connecting assembly 17 and the second connecting assembly 18 are respectively arranged in the diagonal direction of the tray 16. Each set of connecting rods 19 includes two connecting rods, which are respectively arranged on adjacent sides. When the connecting rods 19 are extended, they pass through the hanging holes 15 to hang the tray 16 on the transmission assembly 12 or the fixing assembly 13.

[0053] In an optional embodiment, the warehousing system further includes a drive control module for driving and controlling the rotation of the transmission component and the fixed component.

[0054] In an optional embodiment, a storage entry button and a storage exit button may also be provided on the shelf 11. When the user triggers the storage entry button, the drive control unit drives the first chain assembly to rotate, thereby causing the goods to be stored to rise. When the user triggers the storage exit button, the drive control unit drives the transmission assembly to move the goods to be stored to the bottom of the shelf.

[0055] The working principle of the storage and outbound system of this embodiment is as follows:

[0056] When the goods need to be put into storage, the staff puts the goods to be put into storage on the pallet. The pallet 16 automatically extends out of the first connecting component 17 and is hung on the transmission component 12. Driven by the transmission component 12, the pallet rises along the shelf 11 to a specific position. When it reaches the specific position, the pallet extends out of the second connecting component 18 and is hung on the fixing component 13 for storage.

[0057] When it is necessary to ship out of the warehouse, the tray 16 extends out of the first connecting component 17 and is hung on the transmission component 12, then retracts the second connecting component 18, and is driven by the transmission component 12 to descend to the bottom along the shelf 11 for shipping out of the warehouse.

[0058] The warehousing and outgoing system of the embodiment of the present invention utilizes the lifting and lowering of a chain group to drive the up and down flow of goods, thereby realizing automatic warehousing and outgoing, thereby improving the safety of warehousing and outgoing operations, improving the convenience and safety of warehousing and outgoing operations, and reducing costs.

[0059] like Figure 3 As shown, an elastic component 21 is further provided on the tray 16 , and the elastic component 21 is connected to the first connecting component 17 and the second connecting component 18 respectively to drive the connecting rod 19 to extend and retract.

[0060] As a specific example, the elastic component 21 may include a spring and a hydraulic device. When the hydraulic device has no force applied, the spring is in a natural state, and the connecting rod is in an extended state; when the hydraulic device is compressed, the spring is stretched and the connecting rod retracts.

[0061] In an optional embodiment, a distance sensor 22 and a reflective plate 23 cooperating with the distance sensor 22 are provided on the side of the tray 16;

[0062] A control unit 24 is further provided on the tray 16 , and the control unit 24 controls the elastic component 21 according to the measurement data of the distance measuring sensor 22 .

[0063] As a specific example, the distance measuring sensor 22 includes a first distance measuring sensor, a second distance measuring sensor, and a third distance measuring sensor; the first distance measuring sensor is used to sense the distance between the current pallet and the pallet located above the current pallet, the second distance measuring sensor is used to sense the distance between the current pallet and the pallet located below the current pallet, and the third distance measuring sensor is used to sense the distance between the current pallet and the top of the shelf 11. The first, second, and third distance measuring sensors can be arranged on the same side of the pallet or on different sides, and the present invention is not limited thereto.

[0064] Figure 4-1 and Figure 4-2 It is a structural diagram of a warehousing and outgoing system according to another embodiment of the present invention. Figure 5 Schematic diagram of the structure of a tray according to another embodiment of the present invention. Figure 4-1 、 4-2 and Figure 5 , the warehousing and outbound system includes:

[0065] The shelf 11 includes an inlet rack 111 and an outlet rack 112, each of which is provided with a transmission assembly 12 and a fixing assembly 13. The transmission directions of the transmission assembly 12 and the fixing assembly 13 are both perpendicular to the horizontal plane, and the transmission assembly 12 and the fixing assembly 13 are provided with double-ear hanging holes 15. The transmission assembly 12 and the fixing assembly 13 each include two independent chains 14, and the two independent chains 14 are located on opposite surfaces. As an example, the two independent chains included in the transmission assembly 12 are respectively located on the left and right sides of the shelf 11, and the two independent chains included in the fixing assembly 13 are respectively located on the front and rear sides of the shelf 11. As a more preferred embodiment, as shown in FIG4 , the chain included in the transmission assembly 12 is provided on a diagonal frame of the shelf 11, and the chain included in the fixing assembly 13 is provided on another diagonal frame of the shelf 11. Placing the chains of the transmission assembly 12 and the fixed assembly 13 on diagonally aligned racks ensures a smoother ascent and descent of the pallets along the shelves. In an optional embodiment, the inbound rack 111 and outbound rack 112 are divided into several layers, each representing a storage location, numbered from bottom to top. The distance between each layer is equal to the distance between the attachment holes.

[0066] The track 25 is installed on the top of the inbound rack 111 and the outbound rack 112 .

[0067] A tray 16 is provided with a first connecting component 17 and a second connecting component 18, wherein the first connecting component 17 and the second connecting component 18 respectively include a retractable connecting rod 19; when the connecting rod 19 is extended, the connecting rod 19 passes through the hanging hole 15 so that the tray 16 is hung on the transmission component 12 or the fixing component 13; the first connecting component 17 and the second connecting component 18 are respectively arranged in the diagonal direction of the tray 16, and each group of connecting rods 19 includes two connecting rods, which are respectively arranged on adjacent side surfaces.

[0068] The tray 16 is also provided with an elastic assembly 21, which is connected to the first and second connecting assemblies 17 and 18, respectively, to drive the connecting rod 19 to extend and retract. A distance sensor 22 and a reflector 23 cooperating with the distance sensor 22 are provided on the side of the tray 16. A control unit 24 is also provided on the tray 16 to control the elastic assembly 21 based on the measurement data from the distance sensor 22. This control unit 24 can communicate wirelessly with the drive control module described above. Once the control unit 24 determines the position of the tray based on the measurement data from the distance sensor 22, it can send a signal to the drive control module to stop the rotation of the transmission assembly or the fixed assembly.

[0069] The pallet 16 is also provided with wheels 26. When the pallet 16 is driven by the transmission assembly 12 to rise along the inbound rack 111 to the top of the inbound rack 111, the pallet 16 is driven by the wheels 26 to move along the track 25 to the outbound rack 112. The pallet 16 is also provided with a push-pull device 28 connected to the wheels 26. When the pallet 16 reaches the top of the inbound rack 111, the push-pull device 28 controls the wheels 26 to extend.

[0070] A vacancy detector 27 is provided on the side of the pallet 16 close to the outgoing shelf 112, which is used to detect whether the top of the outgoing shelf 112 is empty when the pallet 16 reaches the top of the incoming shelf 111. The vacancy detector 27 is electrically connected to the control unit 24. The control unit 24 takes the vacancy detector as a specific example. The vacancy detector can also be a ranging sensor, such as an ultrasonic sensor. If the top of the outgoing shelf 112 is vacant, the ultrasonic wave emitted by the ultrasonic sensor will not be reflected back, and the control unit 24 cannot receive the return signal, so it is determined that the top of the outgoing shelf 112 is vacant. When it is determined that the top of the outgoing shelf 112 is vacant, the control unit 24 can control the pallet at the top of the incoming shelf 111 to move to the top of the outgoing shelf 112.

[0071] The operating principle of the in-and-out system of this embodiment is as follows: in response to an in-warehouse operation, the retractable connecting rod 19 on the pallet 16 automatically extends and hooks into the hook hole 15 of the transmission assembly 12 of the shelf 11; the transmission assembly 12 is controlled to rotate to drive the pallet 16 to rise along the shelf 11 to a specific position; when reaching the specific position, the pallet extends the second connecting assembly 18 and hooks onto the fixed assembly 13 for storage; in response to an out-warehouse operation, the pallet 16, driven by the transmission assembly 12, descends along the shelf 11 to the bottom end for out-warehouse. Whether the pallet 16 has reached the specific position is determined based on measurement data from a distance sensor provided on the pallet 16.

[0072] Specifically, such as Figure 4-2 and Figure 6 As shown, in Figure 4-2 The shelf on the left in the middle is the input shelf, and the shelf on the right is the output shelf. Gears are installed on the eight top corners of the input shelf and the output shelf. The gears are perpendicular to the ground, and chains are engaged on the upper and lower opposite gears. Chains in diagonal directions form a group, such as a transmission assembly used to lift a pallet. The transmission assembly is responsible for carrying multiple pallets of goods and for synchronously lifting the multi-layer pallets it carries. For example, after the goods on the top storage position of the input shelf are moved into the output shelf, the top storage position of the input shelf is vacant, and the goods on the fixed assembly need to be moved up as a whole. A motor (not shown in the figure) is used at the bottom of the input shelf as a power device to drive the transmission assembly and the fixed assembly.

[0073] When a pallet needs to be stored, it is attached to the transmission assembly via the first connecting assembly. The transmission assembly drives the pallet upward along the incoming shelf. During this upward movement, the first distance sensor on the pallet detects whether there is another pallet above it. If so, the distance between the current pallet and the pallet above it is determined based on the measurement data from the first distance sensor. When the distance between the current pallet and the pallet above it reaches a preset height, the control unit sends a signal to the power unit to stop the transmission assembly, and the goods stop rising. The current pallet then extends through the second connecting assembly and attaches to the fixed assembly, while the first connecting assembly retracts to store the goods on the pallet. If no pallet is detected above the current pallet, the transmission assembly continues to ascend until the third distance sensor detects that the pallet is at a preset height from the top of the incoming shelf. The control unit then sends a signal to the power unit to stop the transmission assembly and the goods stop rising. If at this point, a vacancy detector on the pallet detects that the top of the outgoing shelf is full (i.e., a pallet is present), the second connecting assembly of the pallet is controlled to extend and attach to the fixed assembly for storage (the first connecting assembly may or may not retract, as is not limited herein). If at this time, the vacancy detector installed on the pallet detects that the top of the outgoing shelf is vacant, the control unit controls the push-pull device to extend the wheels and fall on the track, and drives the wheels to rotate, so that the pallet moves to the outgoing shelf. Since the distance between the incoming shelf and the outgoing shelf is fixed, and the length of the track is also fixed, the distance the pallet moves can be controlled by a program when moving from the incoming shelf to the outgoing shelf. When the distance is met, the movement stops, and the pallet moves to the outgoing shelf. The second distance measuring sensor installed on the pallet detects whether there is a pallet under the pallet. If not, the first connecting component of the pallet is controlled to extend and hang on the transmission component of the outgoing shelf. Driven by the transmission component, it moves downward until the pallet below is detected or the first layer of the outgoing shelf is reached.

[0074] When the goods need to be shipped out, the transmission component of the outgoing shelf is controlled to drive the pallet down to the bottom of the outgoing shelf. When there are multiple goods to be shipped out, the fixed component of the outgoing shelf can be controlled to drive all the pallets down to improve the efficiency of shipping out.

[0075] The warehousing and outgoing system of the embodiment of the present invention utilizes the lifting and lowering of a chain group to drive the up and down flow of goods, thereby realizing automatic warehousing and outgoing, thereby improving the safety of warehousing and outgoing operations, improving the convenience and safety of warehousing and outgoing operations, and reducing costs.

[0076] In an optional embodiment, if Figure 6 As shown, tracks are also set up at the bottom of the incoming shelf 111 and the outgoing shelf 112. When shipping, after the user removes the goods from the pallet, the pallet can be controlled to move to the bottom of the incoming shelf 111.
