DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described in conjunction with specific implementation methods below. The same figure marks in the accompanying drawings represent the same components. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Compared to the embodiments shown in the drawings, feasible embodiments within the scope of the present invention may have fewer components, other components not shown in the drawings, different components, differently arranged components, or differently connected components, etc. In addition, two or more components in the drawings may be implemented in a single component, or a single component shown in the drawings may be implemented as multiple separate components.

[0042] Example 1

[0043] Embodiment 1 of the present invention provides a conveying mechanism 10, and in particular, may be a conveying mechanism 10 capable of conveying goods in two different horizontal directions, so as to effectively improve the flexibility of the conveying mechanism 10 when conveying goods.

[0044] Among them, the conveying mechanism 10 disclosed in this embodiment has a conveying surface suitable for carrying goods. In addition, the conveying mechanism 10 is also configured to be able to convey the goods on the conveying surface toward one of a first horizontal direction and a second horizontal direction. That is, the conveying mechanism 10 can have the ability to convey goods along the first horizontal direction and the ability to convey goods along the second horizontal direction. Among them, when the conveying mechanism 10 exerts the ability to convey goods along the first horizontal direction, the goods on the conveying surface can move along the first horizontal direction; correspondingly, when the conveying mechanism 10 exerts the ability to convey goods along the second horizontal direction, the goods on the conveying surface can move along the second horizontal direction. In this way, the conveying surface has the ability to convey goods in at least two different horizontal directions.

[0045] It is worth noting that the horizontal first direction and the horizontal second direction described in this embodiment are perpendicular to each other. For example, the horizontal first direction described in this embodiment can be Figure 1 The X-axis direction shown in FIG. , the horizontal second direction can be Figure 1 The Y-axis direction shown in FIG. Accordingly, the vertical direction to be described below can be Figure 1 The Z-axis direction shown in .

[0046] The conveying mechanism 10 may be constructed in the following manner, but is not limited to the following manner, so that it has the ability to convey goods in at least two different directions.

[0047] like Figure 1 and 2 As shown in the figure, Figure 1 : shows a schematic structural diagram of an exemplary conveying mechanism 10 disclosed in this embodiment, Figure 2 for Figure 1 2 is a cross-sectional view of the conveying mechanism 10 shown in FIG.

[0048] exist Figure 1 and Figure 2 In the conveying mechanism 10 shown, the conveying surface of the conveying mechanism 10 may further include a conveying surface A and a conveying surface B. The conveying surface A and the conveying surface B are two conveying surfaces that can overlap each other in the vertical direction, that is, viewed from the vertical direction, the conveying surface A and the conveying surface B overlap each other, so that any one of the conveying surface A and the conveying surface B can be used as the conveying surface of the conveying mechanism 10 alone.

[0049] In this embodiment, when the conveying surface A is used as the conveying surface of the conveying mechanism 10, the goods can be carried on the conveying surface A. At this time, if the conveying mechanism 10 performs the action of conveying the goods, the goods carried on the conveying surface A can move in the first horizontal direction; correspondingly, when the conveying surface B is used as the conveying surface of the conveying mechanism 10, the goods can be carried on the conveying surface B. At this time, if the conveying mechanism 10 performs the action of conveying the goods, the goods carried on the conveying surface B can move in the second horizontal direction.

[0050] Specifically, the conveying mechanism 10 may include a plurality of rollers 11 and a plurality of rollers 12. The plurality of rollers 11 are sequentially arranged along a first horizontal direction, the axis of each roller 11 is parallel to a second horizontal direction, and each roller 11 can rotate around its own axis. In addition, the plurality of rollers 11 are in the same horizontal plane, so that a conveying surface A suitable for carrying goods is defined by the plurality of rollers 11. The conveying surface A may be a plane formed by the vertices of the plurality of rollers 11.

[0051] In this way, when the goods are carried on the conveying surface A, if all or part of the multiple rollers 11 rotate, the goods carried on the conveying surface A can move along the horizontal first direction under the action of the rollers 11, thereby enabling the conveying mechanism 10 to have the ability to convey the goods along the horizontal first direction.

[0052] The plurality of rollers 12 are sequentially arranged along the second horizontal direction, the axis of each roller 12 is parallel to the first horizontal direction, and each roller 12 can rotate around its own axis. In addition, the plurality of rollers 12 are located in the same horizontal plane, so that a conveying surface B suitable for carrying goods is defined by the plurality of rollers 12. The conveying surface B can be a plane formed by the vertices of the plurality of rollers 12.

[0053] Thus, when the goods are carried on the conveying surface B, if all or part of the multiple rollers 12 rotate, the goods can move along the second horizontal direction under the action of the rollers 12, thereby enabling the conveying mechanism 10 to have the ability to convey the goods along the second horizontal direction.

[0054] Furthermore, the plurality of rollers 12 are further configured to be able to move between a first position and a second position in a vertical direction. When the plurality of rollers 12 are in the first position, the conveying surface B is lower than the conveying surface A; Figure 2 In the second position shown, the conveying surface B is higher than the conveying surface A. In this way, the conveying mechanism 10 has the ability to convey the goods in any one of the horizontal first direction and the horizontal second direction.

[0055] Specifically, assuming that in the initial state, the plurality of rollers 12 are all in the first position, and the conveying surface B is lower than the conveying surface A, the goods can be carried on the conveying surface A. On this basis, if all or part of the plurality of rollers 11 rotate, the goods carried on the conveying surface A can move along the first horizontal direction under the action of the rollers 11, so as to realize the conveying of the goods in the first horizontal direction. Conversely, if the goods need to be conveyed in the second horizontal direction, the plurality of rollers 12 are first moved vertically from the first position to the second horizontal direction. Figure 2 In the second position shown, when the multiple rollers 12 are in the second position, since the conveying surface B is higher than the conveying surface A at this time, the goods can be carried on the conveying surface B. On this basis, if all or part of the multiple rollers 12 rotate, the goods carried on the conveying surface B can move along the second horizontal direction under the action of the rollers 12, so as to realize the conveying of the goods in the second horizontal direction.

[0056] It can be seen that the conveying mechanism 10 disclosed in this embodiment, by arranging the rollers 11 and the drums 12 in the first horizontal direction and the second horizontal direction respectively, enables the conveying mechanism 10 to have the ability to convey goods in two different horizontal directions, effectively improves the flexibility of the conveying mechanism 10 when in use, and helps to optimize the layout of the storage system and improve the space utilization rate of the storage system. At the same time, when the conveying mechanism 10 conveys the goods in the first horizontal direction, only the rollers 11 are in contact with the goods, and when the conveying mechanism 10 conveys the goods in the second horizontal direction, only the drums 12 are in contact with the goods, so it helps to reduce the friction between the goods and the relevant components in the conveying mechanism 10 when the goods are conveyed in one of the first horizontal direction and the second horizontal direction, thereby helping the goods to move reliably and smoothly in the target direction.

[0057] The movement of the plurality of rollers 12 between the first position and the second position may be achieved, but is not limited to, in the following manner.

[0058] Combination Figure 1 and Figure 2 As shown, the conveying mechanism 10 further includes a fixed frame 13, a mobile frame 14, an elastic member 15 and an electromagnet 16. The plurality of rollers 11 are rotatably arranged on the fixed frame 13, wherein the position of the fixed frame 13 is immutable relative to the mobile frame 14, so that the positions of the plurality of rollers 11 are immutable relative to the plurality of rollers 12. The mobile frame 14 may be located above the fixed frame 13, and the plurality of rollers 12 are rotatably arranged on the mobile frame 14.

[0059] The elastic member 15 is connected between the fixed frame 13 and the movable frame 14. For example, one end of the elastic member 15 may be connected to the top surface of the fixed frame 13, and the other end of the elastic member 15 may be connected to the bottom surface of the movable frame 14, so that the movable frame 14 together with the plurality of rollers 12 are elastically maintained at the second position by the elastic member 15. The elastic member 15 may be a spring.

[0060] The electromagnet 16 can be set on the fixed frame 13, for example, the top surface of the fixed frame 13, and the electromagnet 16 is configured to generate a magnetic force to attract the movable frame 14 when powered on, and the magnetic force is greater than the elastic force applied to the movable frame 14 by the elastic member 15, so that the movable frame 14 together with the multiple rollers 12 can be maintained in the first position.

[0061] Thus, assuming that in the initial state, the electromagnet 16 is in a powered-on state, at this time, since the magnetic force generated by the electromagnet 16 is greater than the elastic force of the elastic member 15, the movable frame 14 will overcome the elastic force of the elastic member 15 under the action of the magnetic force generated by the electromagnet 16 and drive the plurality of rollers 12 to remain in the first position. At this time, the elastic member 15 will be in a compressed state, and the plurality of rollers 11 can be used to transport the goods; correspondingly, when the electromagnet 16 is powered off, the magnetic force acting on the movable frame 14 disappears. At this time, the movable frame 14 will drive the plurality of rollers 12 to move upward from the first position to the position as shown in the figure below under the action of the elastic force released by the elastic member 15. Figure 2 In the second position shown, multiple rollers 12 can be used to transport goods. It can be seen that based on the above configuration, the multiple rollers 12 can be driven to move back and forth between the first position and the second position by the movable frame 14 by only controlling the on and off of the electromagnet 16.

[0062] It is understandable that in actual implementation, the stability and reliability of the moving frame 14 when moving in the vertical direction can be improved by sequentially arranging a plurality of elastic members 15 and a plurality of electromagnets 16 along the circumference of the moving frame 14. At the same time, in order to avoid interference between the rollers 12 and the rollers 11 when the plurality of rollers 12 move between the first position and the second position, Figure 1 As shown, the rollers 12 and the rollers 11 may be arranged in a staggered manner.

[0063] In order to enable all or part of the plurality of rollers 11 and all or part of the plurality of rollers 12 to rotate, the conveying mechanism 10 may further include a roller driving assembly and a roller driving assembly. The roller driving assembly is configured to drive the plurality of rollers 11 in the conveying mechanism 10 to rotate synchronously, and the roller driving assembly is configured to drive the plurality of rollers 12 in the conveying mechanism 10 to rotate synchronously.

[0064] Reference Figure 2As shown, the roller drive assembly may include a roller drive motor (not shown) and a transmission roller 17. The transmission roller 17 is rotatably disposed on the fixed frame 13 below the roller 11, and the axis of the transmission roller 17 is parallel to the axis of the roller 11. In addition, the transmission roller 17 may be connected to each roller 11 by a conventional transmission mechanism such as a belt drive or a chain drive. The roller drive motor may be disposed on the fixed frame 13, and the roller drive motor is connected to the transmission roller 17 to drive the transmission roller 17 to rotate.

[0065] Thus, when the roller drive motor drives the transmission roller 17 to rotate, based on the transmission connection between each roller 11 in the conveying mechanism 10 and the transmission roller 17, each roller 11 will rotate synchronously under the transmission action of the transmission roller 17. In this way, the purpose of using one roller drive motor to drive each roller 11 in the conveying mechanism 10 to rotate synchronously is achieved.

[0066] The number of rollers 11 in the conveying mechanism 10 can be set as required, and refer to Figure 1 As shown, multiple rollers 11 in the same horizontal direction (e.g., the second horizontal direction) can be used as a group of roller groups, and the transmission rollers 17 can be arranged in a one-to-one correspondence with the roller groups, wherein each roller 11 in each roller group can be transmission-connected to the corresponding transmission roller 17, and each transmission roller 17 (that is, between two adjacent transmission rollers 17) is transmission-connected to each other, and the roller drive motor is transmission-connected to one of the transmission rollers 17. In this way, when the roller drive motor drives the transmission roller 17 transmission-connected thereto to rotate, all the transmission rollers 17 will rotate synchronously, and accordingly, the rollers 11 in each roller group corresponding to the transmission roller 17 will also rotate synchronously. This method is helpful to arrange more rollers 11 in the conveying mechanism 10.

[0067] The roller drive assembly may include a roller drive motor (not shown). Two adjacent rollers 12 in the conveying mechanism 10 may be connected by a conventional transmission mechanism such as a belt drive or a chain drive, and the roller drive motor may be fixed on the mobile frame 14, and the roller drive motor is connected to one of the rollers 12. In this way, when the roller drive motor drives the roller 12 connected to it to rotate, each roller 12 will rotate synchronously. This achieves the purpose of using one roller drive motor to drive each roller 12 in the conveying mechanism 10 to rotate synchronously.

[0068] Example 2

[0069] Based on Example 1, Figures 3 to 5 As shown in the content, this embodiment provides a conveying device 20, which includes the conveying mechanism 10 described in the above-mentioned embodiment 1.

[0070] It can be understood that the conveying device 20 disclosed in this embodiment adopts the conveying mechanism 10 described in the above embodiment 1, so that the conveying device 20 at least has the beneficial effects of the above-mentioned conveying mechanism 10, that is, it has the ability to transport goods in two different horizontal directions.

[0071] For example, if the conveying device 20 is applied to a storage system, the conveying device 20 may have the following features: Figure 3 The structure shown. Figure 3 In the conveying device shown, a first inlet and outlet 21 in the horizontal first direction and a second inlet and outlet 22 in the horizontal second direction can be additionally provided in the conveying device 20. The first inlet and outlet 21 is suitable for the passage of goods moving on the conveying surface A, and the second inlet and outlet 22 is suitable for the passage of goods moving on the conveying surface B.

[0072] On this basis, cargo positions corresponding to and aligned with the first inlet and outlet 21 and the second inlet and outlet 22 can be arranged in the circumferential direction of the conveying device 20 .

[0073] Thus, when the conveying mechanism 10 in the conveying device 20 conveys the goods in the first horizontal direction, the goods can pass through the first inlet and outlet 21 to reach the cargo position corresponding to the first inlet and outlet 21; correspondingly, when the conveying mechanism 10 in the conveying device 20 conveys the goods in the second horizontal direction, the goods can pass through the second inlet and outlet 22 to reach the cargo position corresponding to the second inlet and outlet 22. Thus, the conveying device 20 can be used to convey the goods to different cargo positions.

[0074] At the same time, the conveying mechanism 10 can be configured to be capable of reciprocating linear movement in the vertical direction. At this time, cargo positions at different heights can be sequentially arranged along the moving path of the conveying mechanism 10, so that the conveying mechanism 10 can transfer the cargo to cargo positions at different heights for storage.

[0075] The reciprocating linear movement of the conveying mechanism 10 along the vertical direction can be achieved in the following manner but is not limited thereto.

[0076] Specifically, the conveying device 20 may further include a moving assembly, which is configured to drive the conveying mechanism 10 to perform reciprocating linear movement in the vertical direction.

[0077] Combination Figure 3 or Figure 5As shown, the moving assembly may include a moving gear 23 and a fixed rack (not shown in the figure). The moving gear 23 is rotatably disposed on the conveying mechanism 10, for example, on the fixed frame 13 of the conveying mechanism 10, and the moving gear 23 can be rotated under the drive of a driving device such as a motor (not shown in the figure). The fixed rack extends and is fixed along the moving path of the conveying mechanism 10, and the moving gear 23 is meshed with the fixed rack.

[0078] In this way, the entire conveying mechanism 10 can be driven to move along the extension direction of the fixed rack by rotating the moving gear 23 on the conveying mechanism 10. The moving gears 23 can be arranged at the four corners of the bottom of the fixed frame 13 of the conveying mechanism 10 to improve the reliability of the conveying mechanism 10 when moving.

[0079] Combination Figure 5 As shown, the conveying device 20 may also include an image acquisition component 24 disposed above the conveying surface of the conveying mechanism 10, and the image acquisition component 24 is configured to acquire image information of the goods conveyed by the conveying mechanism 10, especially image information of the goods carried on the conveying surface of the conveying mechanism 10, and send the image information to the back-end terminal so that the back-end terminal can observe the situation of the goods carried on the conveying surface in real time. Among them, the image acquisition component 24 may be a camera disposed above the conveying surface.

[0080] Example 3

[0081] On the basis of this embodiment 1, considering that the warehousing systems known in the prior art usually still use conventional shelves that can only provide cargo spaces for storing goods, for such shelves, since the goods at the cargo spaces cannot move autonomously, it is difficult to realize automatic transfer of goods.

[0082] To this end, combined Figure 6 and Figure 7 As shown in the content, this embodiment further provides a shelf, which includes at least one storage layer 30, and the storage layer 30 includes cargo spaces suitable for storing goods. In addition, the conveying mechanism 10 described in the above embodiment 1 is provided at the cargo space.

[0083] It can be understood that the shelf disclosed in this embodiment, by arranging the conveying mechanism 10 described in the above embodiment 1 at the cargo position, enables each cargo position of the shelf to have the ability to transfer goods autonomously, thereby facilitating the automatic transfer of goods.

[0084] The shelf may have multiple storage layers 30, and the multiple storage layers 30 may be arranged in sequence along the vertical direction to increase the amount of goods that the shelf can store. At the same time, each storage layer 30 may also have multiple cargo locations, and the multiple cargo locations may be arranged in pairs.

[0085] For example, the drawings of this embodiment show a situation where the shelf has three storage layers 30 arranged in sequence along the vertical direction, and Figure 6 In the rack shown, the rack may also include Figure 7 The moving passage 40 shown is suitable for arranging a conveying device 20 for conveying goods, such as the conveying device 20 described in Example 2, so as to transfer goods to storage layers 30 at different heights by using the conveying device 20. At this time, multiple cargo locations of each storage layer 30 are arranged adjacent to each other on the same horizontal plane along the circumference of the moving passage 40.

[0086] For example, each storage layer 30 may include eight cargo locations, which are arranged adjacent to each other in the same horizontal plane along the circumference of the moving channel 40. Of course, in other embodiments of the present invention, the multiple cargo locations of each storage layer 30 may also have other arrangements, such as a rectangular array arrangement.

[0087] It can be understood that when there are multiple cargo locations on each storage layer 30 and the multiple cargo locations are adjacent to each other, when one of the cargo locations receives the goods from the conveying device 20, the goods can be transferred to any cargo location under the action of the conveying mechanism 10 at each cargo location, thereby further facilitating the automatic transfer of the goods.

[0088] Example 4

[0089] Based on Example 3, considering that the roller drive motor and drum drive motor are separately arranged for the conveying mechanism 10 at each cargo position, there is a problem of high construction and use costs. Figures 7 to 9 As shown in the content, this embodiment also provides another structural form of shelf. Different from Example 3, this embodiment also makes further improvements to the conveying mechanism 10 at each cargo position, in the hope of further reducing the construction and use costs of the shelf when there are multiple cargo positions in the storage layer 30.

[0090] Reference Figure 7 As shown, in this embodiment, the multiple cargo positions of each storage layer 30 further include a first cargo position 31 in the horizontal first direction, a second cargo position 32 in the horizontal second direction, and a third cargo position 33 adjacent to both the first cargo position 31 and the second cargo position 32.

[0091] For example, the drawings of this embodiment show that each storage layer 30 may include eight Figure 7 The eight cargo positions shown are arranged in a rectangular shape, and specifically include two first cargo positions 31 in a first horizontal direction, two second cargo positions 32 in a second horizontal direction, and four third cargo positions 33 that are adjacent to both the first cargo positions 31 and the second cargo positions 32 .

[0092] For example, in this embodiment, the eight cargo locations of each storage layer 30 are defined as follows: Figure 7 As shown in the cargo positions 1-8, among cargo positions 1-8, cargo positions 1, 3, 6, and 8 can be understood as the third cargo position 33 that is adjacent to both the first cargo position 31 and the second cargo position 32, cargo positions 4 and 5 can be understood as the two first cargo positions 31, and cargo positions 2 and 7 can be understood as the two second cargo positions 32.

[0093] On this basis, combined with Figure 8 As shown in the content, this embodiment further defines that one of the rollers 12 in the conveying mechanism 10 at the third cargo position 33 adjacent to each first cargo position 31 is connected to one of the rollers 12 in the conveying mechanism 10 at the corresponding first cargo position 31 through a first transmission mechanism 34; and, the rollers 12 in the conveying mechanism 10 at the third cargo position 33 adjacent to each first cargo position 31 share a movable frame 14 with the rollers 12 in the conveying mechanism 10 at the corresponding first cargo position 31.

[0094] For example, in this embodiment, for the conveying mechanisms 10 at cargo positions No. 1, No. 4, and No. 6, one of the rollers 12 in the conveying mechanism 10 at cargo position No. 1 is connected to one of the rollers 12 in the conveying mechanism 10 at cargo position No. 4 through the first transmission mechanism 34, and one of the rollers 12 in the conveying mechanism 10 at cargo position No. 4 is connected to one of the rollers 12 in the conveying mechanism 10 at cargo position No. 6. In addition, the rollers 12 in the conveying mechanisms 10 at cargo positions No. 1, No. 4, and No. 6 share a moving frame 14, so that all the rollers 12 in the conveying mechanisms 10 at cargo positions No. 1, No. 4, and No. 6 can be driven to move synchronously between the first position and the second position through the moving frame 14. Correspondingly, refer to Figure 8 As shown, for the conveying mechanisms 10 at cargo positions No. 3, No. 5 and No. 8, one of the rollers 12 in the conveying mechanism 10 at cargo position No. 3 is transmission-connected with one of the rollers 12 in the conveying mechanism 10 at cargo position No. 5 through the first transmission mechanism 34, and one of the rollers 12 in the conveying mechanism 10 at cargo position No. 5 is transmission-connected with one of the rollers 12 in the conveying mechanism 10 at cargo position No. 8. Moreover, at this time, the rollers 12 in the conveying mechanisms 10 at cargo positions No. 3, No. 5 and No. 8 share a moving frame 14, so that all the rollers 12 in the conveying mechanisms 10 at cargo positions No. 3, No. 5 and No. 8 can be driven by the moving frame 14 to move synchronously between the first position and the second position.

[0095] In this way, for the conveying mechanisms 10 at the three cargo positions 1, 4 and 6, when one roller 12 in the conveying mechanism 10 at cargo position 4 belonging to the first cargo position 31 rotates, the roller 12 in the conveying mechanism 10 at cargo position 4 can provide the rollers 12 in the conveying mechanisms 10 at cargo positions 1 and 6 with power to force them to rotate. Similarly, for the conveying mechanisms 10 at the three cargo positions 3, 5 and 8, when one roller 12 in the conveying mechanism 10 at cargo position 5 belonging to the first cargo position 31 rotates, the roller 12 in the conveying mechanism 10 at cargo position 5 can provide the rollers 12 in the conveying mechanisms 10 at cargo positions 3 and 8 with power to force them to rotate.

[0096] Combination Fig. 9 As shown, one of the transmission rollers 17 in the conveying mechanism 10 at the third cargo position 33 adjacent to the second cargo position 32 is connected to one of the transmission rollers 17 in the conveying mechanism 10 at the corresponding second cargo position 32 via a second transmission mechanism 35.

[0097] For example, in this embodiment, for the conveying mechanisms 10 at the No. 1, No. 2 and No. 3 cargo positions, one of the transmission rollers 17 in the conveying mechanism 10 at the No. 1 cargo position is connected to one of the transmission rollers 17 in the conveying mechanism 10 at the No. 2 cargo position through the second transmission mechanism 35, and one of the transmission rollers 17 in the conveying mechanism 10 at the No. 2 cargo position is connected to one of the transmission rollers 17 in the conveying mechanism 10 at the No. 3 cargo position; refer to Fig. 9 As shown, for the conveying mechanisms 10 at cargo positions No. 6, 7 and 8, one of the drive rollers 17 in the conveying mechanism 10 at cargo position No. 6 is drive connected with one of the drive rollers 17 in the conveying mechanism 10 at cargo position No. 7 through the second transmission mechanism 35, and one of the drive rollers 17 in the conveying mechanism 10 at cargo position No. 7 is drive connected with one of the drive rollers 17 in the conveying mechanism 10 at cargo position No. 8.

[0098] In this way, for the conveying mechanisms 10 at the three cargo positions 1, 2 and 3, when one of the transmission rollers 17 in the conveying mechanism 10 at cargo position 2 belonging to the second cargo position 32 rotates, the transmission roller 17 in the conveying mechanism 10 at cargo position 2 can provide the transmission rollers 17 in the conveying mechanisms 10 at cargo positions 1 and 3 with power to force them to rotate. Similarly, for the conveying mechanisms 10 at the three cargo positions 6, 7 and 8, when one of the transmission rollers 17 in the conveying mechanism 10 at cargo position 7 belonging to the second cargo position 32 rotates, the transmission roller 17 in the conveying mechanism 10 at cargo position 7 can provide the transmission rollers 17 in the conveying mechanisms 10 at cargo positions 6 and 8 with power to force them to rotate.

[0099] It can be understood that, with the above-mentioned arrangement, it is only necessary to arrange a roller drive motor for providing power in the conveying mechanism 10 at the first cargo position 31, so as to provide power for the rollers in the conveying mechanism 10 at the third cargo position 33. Correspondingly, it is only necessary to arrange a roller drive motor for providing power in the conveying mechanism 10 at the second cargo position 32, so as to provide power for the rollers in the conveying mechanism 10 at the third cargo position 33, which helps to further reduce the construction and use costs of the shelves.

[0100] Furthermore, in order to prevent the goods on some cargo positions from being moved out of the corresponding cargo positions when the goods are transferred between different cargo positions, for example, when there are goods on cargo positions 1 and 3, if all the rollers 11 in the conveying mechanisms 10 at cargo positions 1, 2 and 3 are directly rotated synchronously to transfer the goods from cargo position 1 to cargo position 2, the goods at cargo position 3 may be moved out of cargo position 3. At the same time, the above-mentioned situation may occur when transferring goods between cargo positions 6, 7 and 8, between cargo positions 1, 4 and 7, and between cargo positions 3, 5 and 8.

[0101] To this end, this embodiment further defines that the first transmission mechanism 34 and the second transmission mechanism 35 described above are both one-way transmission mechanisms. Figure 8 As shown, the first transmission mechanism 34 may include a first ratchet sprocket 341, which is coaxially arranged with one of the rollers 12 of the conveying mechanism 10 located at the first cargo position 31, and the first ratchet sprocket 341 is rotatably matched with the corresponding roller 12, that is, the first ratchet sprocket 341 can rotate relative to the corresponding roller 12, and the roller 12 coaxially arranged with the first ratchet sprocket 341 is fixedly provided with a first ratchet pawl 342 for controlling the first ratchet sprocket 341 to rotate in a single direction. One of the rollers 12 in the conveying mechanism 10 at the third cargo position 33 adjacent to the first cargo position 31 is connected to the first ratchet sprocket 341 through a first chain 343.

[0102] Accordingly, combined Fig. 9As shown, the second transmission mechanism 35 may include a second ratchet sprocket 351, which is coaxially arranged with one of the transmission rollers 17 of the conveying mechanism 10 located at the second cargo position 32, and the second ratchet sprocket 351 is rotationally matched with the corresponding transmission roller 17, that is, the second ratchet sprocket 351 can rotate relative to the corresponding transmission roller 17, and the transmission roller 17 coaxially arranged with the second ratchet sprocket 351 is fixedly provided with a second ratchet pawl 352 for controlling the second ratchet sprocket 351 to rotate in a single direction. One of the transmission rollers 17 in the conveying mechanism 10 at the third cargo position 33 adjacent to the second cargo position 32 is transmission-connected to the second ratchet sprocket 351 through a second chain 353.

[0103] Among them, refer to Figure 8 or Fig. 9 As shown, the first ratchet sprocket 341 and the second ratchet sprocket 351, the first pawl 342 and the second pawl 352 described in this embodiment have the same structure and working principle. The working principle of the one-way transmission mechanism composed of the ratchet sprocket and the pawl can refer to the flywheel used in bicycles in the prior art. As far as this transmission mechanism is concerned, one-way transmission of power can be achieved.

[0104] Specifically in the embodiments of the present invention, for the conveying mechanisms 10 at cargo positions No. 1, No. 4 and No. 6, on the basis of adopting the above-mentioned one-way transmission mechanism as the first transmission mechanism 34, it can be achieved that: when all the rollers 12 in the conveying mechanisms 10 at cargo positions No. 1 and No. 4 rotate synchronously to transfer the goods from cargo position No. 1 to cargo position No. 4, all the rollers 12 in the conveying mechanism 10 at cargo position No. 6 can remain stationary; correspondingly, when all the rollers 12 in the conveying mechanisms 10 at cargo positions No. 4 and No. 6 rotate synchronously to transfer the goods from cargo position No. 6 to cargo position No. 4, all the rollers 12 in the conveying mechanism 10 at cargo position No. 1 can remain stationary.

[0105] Similarly, the principle of the conveying mechanism 10 at cargo positions No. 3, No. 5 and No. 8 when transferring goods is the same as the principle of the conveying mechanism 10 at cargo positions No. 1, No. 4 and No. 6 mentioned above when transferring goods, and will not be elaborated here.

[0106] For the conveying mechanism 10 at cargo positions No. 1, No. 2 and No. 3, on the basis of adopting the above-mentioned one-way transmission mechanism as the second transmission mechanism 35, it can be achieved that when all the rollers 11 in the conveying mechanism 10 at cargo positions No. 1 and No. 2 rotate synchronously under the action of the corresponding transmission rollers 17 to transfer the goods from cargo position No. 2 to cargo position No. 1, all the transmission rollers 17 in the conveying mechanism 10 at cargo position No. 3 can remain stationary, so that all the rollers 11 in the conveying mechanism 10 at cargo position No. 3 remain stationary; correspondingly, when all the rollers 11 in the conveying mechanism 10 at cargo positions No. 2 and No. 3 rotate synchronously under the action of the corresponding transmission rollers 17 to transfer the goods from cargo position No. 2 to cargo position No. 3, all the transmission rollers 17 in the conveying mechanism 10 at cargo position No. 1 can remain stationary, so that all the rollers 11 in the conveying mechanism 10 at cargo position No. 1 remain stationary.

[0107] Similarly, the principle of the conveying mechanism 10 at cargo positions No. 6, No. 7 and No. 8 when transferring goods is the same as the principle of the conveying mechanism 10 at cargo positions No. 1, No. 2 and No. 3 mentioned above when transferring goods, and will not be described in detail here.

[0108] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
