In the shuttle storage system, it mainly uses shuttles that can move on the shelves to realize the transfer and storage of goods. Although this method can improve the efficiency of goods storage and retrieval and space utilization to a certain extent, it is necessary to build a separate track on the shelf for the shuttle to move, resulting in high construction and use costs and more complex technology.

DETAILED DESCRIPTION

[0050] 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.

[0051] 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.

[0052] Example 1

[0053] On the one hand, embodiment 1 of the present invention provides a storage unit 100, and in particular, can be a storage unit 100 with the ability to move goods, in the hope of achieving the transfer and storage of goods with lower construction and use costs and higher space utilization.

[0054] like Figures 1 to 3 As shown, Figure 1 1 shows a schematic structural diagram of an exemplary storage unit 100 disclosed in this embodiment, Figure 2 for Figure 1 A top view of a storage unit 100 is shown in FIG. Figure 3 for Figure 1 A cross-sectional view of a storage unit 100 is shown in FIG. Figures 1 to 3 In the storage unit 100 shown, the storage unit 100 may include a transfer component 10 and at least one storage layer 20 .

[0055] In this embodiment, the transfer component 10 is mainly used to realize the transfer of goods, specifically including: receiving goods that need to be stored, and transferring the goods that need to be stored to the cargo space of the target storage layer 20 for storage; or receiving goods from the cargo space of the target storage layer 20, and transferring the goods out, so as to facilitate subsequent operations such as shipment of the goods.

[0056] Specifically, combined Figure 4 As shown, the transfer assembly 10 may include a first transfer mechanism 11. The first transfer mechanism 11 defines a first conveying surface suitable for carrying goods. Moreover, the first transfer mechanism 11 is also configured to be able to convey the goods on the first conveying surface toward one of a horizontal first direction and a horizontal second direction.

[0057] 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 4 The X-axis direction shown in FIG. , the horizontal second direction can be Figure 4 The Y-axis direction shown in FIG. Accordingly, the vertical direction to be described below can be Figure 4 The Z-axis direction shown in .

[0058] Among them, the "first transfer mechanism 11 is also configured to be able to transport the goods on the first conveying surface toward one of the first horizontal direction and the second horizontal direction" described in this embodiment means that the first transfer mechanism 11 can have the ability to transport goods along the first horizontal direction and the ability to transport goods along the second horizontal direction. Among them, when the first transfer mechanism 11 exerts the ability to transport goods along the first horizontal direction, the goods on the first conveying surface can move along the first horizontal direction; correspondingly, when the first transfer mechanism 11 exerts the ability to transport goods along the second horizontal direction, the goods on the first conveying surface can move along the second horizontal direction. In this way, the first transfer mechanism 11 has the ability to transport goods in at least two different horizontal directions.

[0059] Continue to refer to Figure 4 The transfer assembly 10 also has a first inlet and outlet 12 in the horizontal first direction for the goods moving in the horizontal first direction to pass through, and a second inlet and outlet 13 in the horizontal second direction for the goods moving in the horizontal second direction to pass through. In this way, when the first transfer mechanism 11 transfers the goods on the first conveying surface toward the horizontal first direction, the goods can pass through the corresponding first inlet and outlet 12; correspondingly, when the first transfer mechanism 11 transfers the goods on the first conveying surface toward the horizontal second direction, the goods can pass through the corresponding second inlet and outlet 13.

[0060] The first transfer mechanism 11 may be constructed in the following manner but is not limited thereto, so that it has the ability to transport goods in at least two different directions.

[0061] The first conveying surface defined by the first transfer mechanism 11 may further include a conveying surface A and a second 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 first conveying surface alone.

[0062] Combination Figures 4 to 6 As shown, the first transfer mechanism 11 may include a plurality of rollers 111 and a plurality of rollers 112. The plurality of rollers 111 are sequentially arranged along a first horizontal direction, the axis of each roller 111 is parallel to a second horizontal direction, and each roller 111 can rotate around its own axis. In addition, the plurality of rollers 111 are located in the same horizontal plane, so that a conveying surface A suitable for carrying goods is defined by the plurality of rollers 111. The conveying surface A may be a plane formed by the vertices of the plurality of rollers 111.

[0063] In this way, when the goods are carried on the conveying surface A, if all or part of the multiple rollers 111 rotate, the goods carried on the conveying surface A can move along the horizontal first direction under the action of the rollers 111, thereby enabling the first transfer mechanism 11 to have the ability to convey the goods along the horizontal first direction.

[0064] The plurality of rollers 112 are sequentially arranged along the second horizontal direction, the axis of each roller 112 is parallel to the first horizontal direction, and each roller 112 can rotate around its own axis. In addition, the plurality of rollers 112 are located in the same horizontal plane, so that a conveying surface B suitable for carrying goods is defined by the plurality of rollers 112. The conveying surface B can be a plane formed by the vertices of the plurality of rollers 112.

[0065] In this way, when the goods are carried on the conveying surface B, if all or part of the multiple rollers 112 rotate, the goods can move along the second horizontal direction under the action of the rollers 112, thereby enabling the first transfer mechanism 11 to have the ability to convey the goods along the second horizontal direction.

[0066] Furthermore, the plurality of rollers 112 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 112 are in the first position, the conveying surface B is lower than the conveying surface A; Figure 6 In the second position shown, the conveying surface B is higher than the conveying surface A. In this way, the first transfer mechanism 11 has the ability to convey the goods on the first conveying surface in any one of the horizontal first direction and the horizontal second direction.

[0067] Specifically, assuming that in the initial state, the plurality of rollers 112 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 111 rotate, the goods carried on the conveying surface A can move along the horizontal first direction under the action of the rollers 111, so that the goods can pass through the corresponding first entrance and exit 12. Conversely, if the goods need to be conveyed along the horizontal second direction, the plurality of rollers 112 are first moved vertically from the first position to the second position. Figure 6 In the second position shown, when the multiple rollers 112 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 112 rotate, the goods carried on the conveying surface B can move along the second horizontal direction under the action of the rollers 112, so that the goods can pass through the corresponding second entrance and exit 13.

[0068] It can be understood that in this way, when the first transfer mechanism 11 transports the goods in the first horizontal direction, only the roller 111 contacts the goods, and when the first transfer mechanism 11 transports the goods in the second horizontal direction, only the roller 112 contacts the goods. Therefore, it helps to reduce the friction between the goods and the relevant components in the first transfer mechanism 11 when the goods are transported 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.

[0069] The movement of the plurality of rollers 112 between the first position and the second position may be achieved, but is not limited to, in the following manner.

[0070] Combination Figure 6 and Figure 7 As shown, the first transfer mechanism 11 further includes a fixed frame 113, a mobile frame 114, an elastic member 115, and an electromagnet 116. A plurality of rollers 111 are rotatably disposed on the fixed frame 113, wherein the position of the fixed frame 113 is immutable relative to the mobile frame 114, so that the positions of the plurality of rollers 111 are immutable relative to the plurality of rollers 112. The mobile frame 114 may be located above the fixed frame 113, and the plurality of rollers 112 are rotatably disposed on the mobile frame 114.

[0071] The elastic member 115 is connected between the fixed frame 113 and the movable frame 114. For example, one end of the elastic member 115 may be connected to the top surface of the fixed frame 113, and the other end of the elastic member 115 may be connected to the bottom surface of the movable frame 114, so that the movable frame 114 together with the plurality of rollers 112 are elastically maintained at the second position by the elastic member 115. The elastic member 115 may be a spring.

[0072] The electromagnet 116 can be set on the fixed frame 113, for example, the top surface of the fixed frame 113, and the electromagnet 116 is configured to generate a magnetic force to attract the movable frame 114 when powered on, and the magnetic force is greater than the elastic force applied to the movable frame 114 by the elastic member 115, so that the movable frame 114 together with the multiple rollers 112 can be maintained in the first position.

[0073] Thus, assuming that in the initial state, the electromagnet 116 is in a powered-on state, at this time, since the magnetic force generated by the electromagnet 116 is greater than the elastic force of the elastic member 115, the movable frame 114 will overcome the elastic force of the elastic member 115 under the action of the magnetic force generated by the electromagnet 116 and drive the plurality of rollers 112 to remain in the first position. At this time, the elastic member 115 will be in a compressed state, and the plurality of rollers 111 can be used to transport the goods; correspondingly, when the electromagnet 116 is powered off, the magnetic force acting on the movable frame 114 disappears. At this time, the movable frame 114 will drive the plurality of rollers 112 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 115. Figure 6 In the second position shown, the multiple rollers 112 can be used to transport the goods. It can be seen that based on the above configuration, the multiple rollers 112 can be driven to move back and forth between the first position and the second position by the movable frame 114 by only controlling the on and off of the electromagnet 116.

[0074] It is understandable that in actual implementation, the stability and reliability of the moving frame 114 when moving in the vertical direction can be improved by sequentially arranging a plurality of elastic members 115 and a plurality of electromagnets 116 along the circumference of the moving frame 114. At the same time, in order to avoid interference between the rollers 112 and the rollers 111 when the plurality of rollers 112 move between the first position and the second position, refer to Figure 4 As shown, the rollers 112 and the rollers 111 may be arranged in a staggered manner.

[0075] In order to enable all or part of the plurality of rollers 111 and all or part of the plurality of rollers 112 to rotate, the first transfer mechanism 11 may further include a roller drive assembly and a roller drive assembly. The roller drive assembly is configured to drive the plurality of rollers 111 in the first transfer mechanism 11 to rotate synchronously, and the roller drive assembly is configured to drive the plurality of rollers 112 in the first transfer mechanism 11 to rotate synchronously.

[0076] Reference Figure 6 or Figure 7 As shown, the roller drive assembly may include a roller drive motor (not shown) and a transmission roller 117. The transmission roller 117 is rotatably disposed on a fixed frame 113 below the roller 111, and the axis of the transmission roller 117 is parallel to the axis of the roller 111. In addition, the transmission roller 117 may be connected to each roller 111 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 113, and the roller drive motor is connected to the transmission roller 117 to drive the transmission roller 117 to rotate.

[0077] Thus, when the roller driving motor drives the transmission roller 117 to rotate, based on the transmission connection between each roller 111 in the first transfer mechanism 11 and the transmission roller 117, each roller 111 will rotate synchronously under the transmission action of the transmission roller 117. In this way, the purpose of using one roller driving motor to drive each roller 111 in the first transfer mechanism 11 to rotate synchronously is achieved.

[0078] The number of rollers 111 in a single first transfer mechanism 11 can be set as required, and referring to Figure 4 As shown, multiple rollers 111 in the same horizontal direction (e.g., the horizontal second direction) can be used as a group of roller groups, and the transmission rollers 117 can be arranged in a one-to-one correspondence with the roller groups, wherein each roller 111 in each roller group can be transmission-connected to the corresponding transmission roller 117, and each transmission roller 117 (i.e., 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 117. In this way, when the roller drive motor drives the transmission roller 117 transmission-connected thereto to rotate, all the transmission rollers 117 will rotate synchronously, and accordingly, the rollers 111 in each roller group corresponding to the transmission roller 117 will also rotate synchronously. This method is helpful to arrange more rollers 111 in a single first transfer mechanism 11.

[0079] The roller drive assembly may include a roller drive motor (not shown). Two adjacent rollers 112 among the plurality of rollers 112 in the first transfer mechanism 11 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 114, and the roller drive motor is connected to one of the rollers 112. In this way, when the roller drive motor drives the roller 112 connected thereto to rotate, each roller 112 will rotate synchronously. This achieves the purpose of using one roller drive motor to drive each roller 112 in the first transfer mechanism 11 to rotate synchronously.

[0080] In this embodiment, the storage layer 20 is suitable for storing goods. Specifically, the storage layer 20 includes a cargo space suitable for storing goods. Figure 2 and Figure 3 As shown, the cargo positions at least include a first cargo position 21 corresponding to and aligned with the first inlet and outlet 12 , and a second cargo position 22 corresponding to and aligned with the second inlet and outlet 13 .

[0081] The first cargo position 21 is suitable for receiving cargo from the first inlet and outlet 12 of the transfer assembly 10, or transferring cargo stored inside the first cargo position 21 to the first conveying surface of the first transfer mechanism 11 of the transfer assembly 10 through the first inlet and outlet 12. The second cargo position 22 is suitable for receiving cargo from the second inlet and outlet 13 of the transfer assembly 10, or transferring cargo stored inside the first cargo position 21 to the first conveying surface of the first transfer mechanism 11 of the transfer assembly 10 through the second inlet and outlet 13.

[0082] In addition, the first cargo position 21 and the second cargo position 22 of each storage layer 20 in this embodiment are both provided with a second transfer mechanism 23. The second transfer mechanism 23 defines a second conveying surface. In addition, the second transfer mechanism 23 is also configured to be able to convey the cargo on the second conveying surface in one of the horizontal first direction and the horizontal second direction.

[0083] It is worth noting that the structure of the second transfer mechanism 23 described in this embodiment can be substantially the same as the structure of the first transfer mechanism 11, so that the second transfer mechanism 23 can realize the transportation of the goods in one of the horizontal first direction and the horizontal second direction by working in a substantially same manner as the first transfer mechanism 11. The second conveying surface in the second transfer mechanism 23 corresponds to the first conveying surface in the first transfer mechanism 11.

[0084] Based on the above arrangement, when the storage unit 100 disclosed in the present embodiment is actually used, if it is necessary to perform a cargo storage operation (i.e., an operation of storing the cargo in a target cargo position), after the cargo is completely carried on the first conveying surface of the first transfer mechanism 11 of the transfer assembly 10, the cargo can be further carried on the corresponding conveying surface according to the target cargo position to be used for storing the cargo. For example, if it is necessary to store the cargo in the first cargo position 21 of the storage layer 20, the electromagnet 116 in the first transfer mechanism 11 is kept energized to drive the multiple rollers 112 to remain in the first position through the movable frame 114, so that the conveying surface A formed by the multiple rollers 111 in the first transfer mechanism 11 is used to carry the cargo. , and then, it is only necessary to rotate the multiple rollers 111 in the first transfer mechanism 11 to transport the goods to the corresponding first cargo position 21 through the corresponding first entrance and exit 12; correspondingly, if the goods need to be stored in the second cargo position 22 of the storage layer 20, the electromagnet 116 in the first transfer mechanism 11 is powered off, so that the movable frame 114 drives the multiple rollers 112 to remain in the second position under the elastic force of the elastic member 115, thereby utilizing the conveying surface B formed by the multiple rollers 112 in the first transfer mechanism 11 to carry the goods, and then, it is only necessary to rotate the multiple rollers 112 in the first transfer mechanism 11 to transport the goods to the corresponding second cargo position 22 through the corresponding second entrance and exit 13.

[0085] It is worth mentioning that each first cargo position 21 and second cargo position 22 of the storage layer 20 is provided with a second transfer mechanism 23 having a structure and function basically the same as the first transfer mechanism 11. Therefore, when there are goods in the first cargo position 21 and the second cargo position 22, the goods in the first cargo position 21 and the second cargo position 22 can be transferred to the first conveying surface of the first transfer mechanism 11 through the corresponding import and export under the action of the corresponding second transfer mechanism 23 to realize the operation of taking out the goods (that is, the operation of taking out the goods at the cargo position into the transfer component 10), thereby facilitating subsequent operations such as shipment.

[0086] It can be understood that the present embodiment provides a first transfer mechanism 11 on the transfer component 10 that can transport goods along a first horizontal direction and a second horizontal direction, and at the same time arranges cargo spaces suitable for storing goods in the circumference of the transfer component 10, and arranges a second transfer mechanism 23 at each cargo space that can transport goods along the first horizontal direction and the second horizontal direction. This not only enables automatic storage and retrieval of goods, but also facilitates the compact design of the storage unit 100 structure based on the fact that each cargo space has the ability to autonomously transfer goods, so as to effectively improve the space utilization of the storage unit 100. Compared with the cargo storage and retrieval solutions adopted by known warehousing systems, the storage unit 100 disclosed in the present embodiment has lower construction and use costs, and the technology is simpler and easier to implement.

[0087] In order to increase the amount of goods that can be stored in a single storage layer 20 and realize the rational use of limited space, combined with Figure 2 or Figure 8 As shown, the cargo positions of each storage layer 20 may further include a third cargo position 24 that is adjacent to both the first cargo position 21 and the second cargo position 22 .

[0088] For example, in this embodiment Figure 4 FIG. 1 shows a case where the transfer assembly 10 is provided with first inlet and outlet ports 12 on both sides opposite to each other in the first horizontal direction and second inlet and outlet ports 13 on both sides opposite to each other in the second horizontal direction. In this case, each storage layer 20 may include eight storage layers 20. Figure 2 or Figure 8 The eight cargo positions arranged in the circumferential direction of the transfer assembly 10 shown in the figure specifically include two first cargo positions 21, two second cargo positions 22, and four third cargo positions 24. The two first cargo positions 21 are respectively aligned with the two first inlets and outlets 12, the two second cargo positions 22 are respectively aligned with the two second inlets and outlets 13, and the four third cargo positions 24 are adjacent to the corresponding first cargo positions 21 and second cargo positions 22 at the same time.

[0089] For example, in this embodiment, the eight cargo locations of each storage layer 20 are defined as follows: Figure 8As 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 24 that is adjacent to the first cargo position 21 and the second cargo position 22 at the same time, cargo positions 4 and 5 can be understood as the two first cargo positions 21 that are respectively aligned with the two first inlets and outlets 12 of the transfer component 10, and cargo positions 2 and 7 can be understood as the two second cargo positions 22 that are respectively aligned with the two second inlets and outlets 13 of the transfer component 10.

[0090] In addition, each third cargo position 24 of each storage layer 20 in this embodiment is also provided with a second transfer mechanism 23. This allows the transfer of cargo between any two adjacent cargo positions. For example, when cargo from the transfer assembly 10 arrives at the first cargo position 21, the cargo can be transferred to the third cargo position 24 adjacent to the first cargo position 21 by the second transfer mechanism 23 at the first cargo position 21, and the cargo at the third cargo position 24 can also be transferred to the first cargo position 21 by the second transfer mechanism 23 at the third cargo position 24. Similarly, cargo can also be transferred between the adjacent second cargo position 22 and third cargo position 24.

[0091] It can be understood that, by providing the third cargo position 24, not only the amount of cargo that can be stored in a single storage layer 20 is increased, but also the reasonable use of limited space is further achieved, which is conducive to improving space utilization.

[0092] Furthermore, in order to effectively increase the amount of goods that can be stored in the storage unit 100 disclosed in this embodiment, the number of storage layers 20 can be multiple.

[0093] At this time, the transfer assembly 10 is further configured to be able to reciprocate linearly in the vertical direction, and the plurality of storage layers 20 are arranged in sequence along the moving direction of the transfer assembly 10, so that the transfer assembly 10 moving in the vertical direction can sequentially reach the location of each storage layer 20. Figure 1 or Figure 3 FIG. 2 shows a situation where a single storage unit 100 includes three storage layers 20 . Of course, the number of storage layers 20 is not limited thereto and is not limited here.

[0094] In this way, when storing and retrieving goods, it is only necessary to move the transfer component 10 in the vertical direction to different storage layers 20, and align the first inlet and outlet 12 and the second inlet and outlet 13 on the transfer component 10 with the first cargo position 21 and the second cargo position 22 of the corresponding storage layer 20 respectively, so that the transfer component 10 can cooperate with the storage layer 20 to realize the storage and retrieval of goods.

[0095] The reciprocating linear movement of the transfer assembly 10 along the vertical direction may be achieved in the following manner but is not limited thereto.

[0096] Specifically, combined Figure 3 and Fig. 9 As shown in the figure, the storage unit 100 may also include a moving assembly 30, which is configured to drive the transfer assembly 10 to make reciprocating linear movements in the vertical direction. Among them, the moving assembly 30 may include a moving gear 31 and a fixed rack 32. The moving gear 31 is rotatably arranged on the transfer assembly 10, for example, on the fixed frame 113 of the first transfer mechanism 11 in the transfer assembly 10, and the moving gear 31 can be rotated under the drive of a driving device such as a motor (not shown in the figure). The fixed rack 32 extends and is fixed along the moving path of the transfer assembly 10, and the moving gear 31 is meshed with the fixed rack 32. For example, the fixed rack 32 can be fixed on the frame of each storage layer 20.

[0097] In this way, the entire transfer assembly 10 can be driven to move along the extension direction of the fixed rack 32 by rotating the moving gear 31 on the transfer assembly 10. The moving gears 31 can be arranged at the four corners of the bottom of the fixed frame 113 of the first transfer mechanism 11 of the transfer assembly 10 to improve the reliability of the transfer assembly 10 when moving.

[0098] Combination Figure 6 As shown, the transfer assembly 10 may further include an image acquisition component 14 disposed above the first conveying surface of the first transfer mechanism 11, and the image acquisition component 14 is configured to acquire image information of the goods carried on the first conveying surface and send the image information to the back-end terminal so that the back-end terminal can observe the condition of the goods carried on the first conveying surface in real time. The image acquisition component 14 may be a camera disposed above the first conveying surface.

[0099] On the other hand, Fig.12 As shown, embodiment 1 of the present invention further discloses a storage system, which includes at least one of the above-mentioned storage units 100. It can be understood that by adopting the above-mentioned storage unit 100, the storage system at least has the beneficial effects of the above-mentioned storage unit 100, that is, it can realize the automatic storage and retrieval of goods, and can reduce the construction and use costs and improve the space utilization rate.

[0100] In actual implementation, the storage system may include a plurality of storage units 100 arranged in a certain pattern, for example, Fig.12 As shown, the plurality of storage units 100 may be arranged in a rectangular array to optimize the structural design of the entire storage system as much as possible and improve space utilization.

[0101] In addition, the storage system may further include a conveying unit 200, which is suitable for conveying external goods to be stored to the first conveying surface of the first transfer mechanism 11 of the transfer assembly 10 of each storage unit 100, or receiving goods from the transfer assembly 10 of each storage unit 100. The conveying unit 200 may be a conveying device such as a belt conveyor or a roller conveyor.

[0102] Example 2

[0103] On the basis of Example 1, considering that there are multiple storage layers 20, if a driving device such as a roller driving motor or a drum driving motor is arranged for the second transfer mechanism 23 at the first cargo position 21 and the second cargo position 22 of each storage layer 20, a large construction and use cost will be generated. For this reason, this embodiment provides a storage unit 100 of another structural form. Different from Example 1, this embodiment further improves the second transfer mechanism 23 at the first cargo position 21 and the second cargo position 22 of each storage layer 20, so as to further reduce the construction and use cost of the storage unit 100.

[0104] Specifically, in the second transfer mechanism 23 provided at each of the first cargo position 21 and the second cargo position 22, the roller drive motor and the drum drive motor in the second transfer mechanism 23 are both provided on the transfer assembly 10. For example, the roller drive motor may be fixedly provided on the fixed frame 113 of the first transfer mechanism 11; the drum drive motor may be provided on the mobile frame 114 of the first transfer mechanism 11, so that the drum drive motor in the second transfer mechanism 23 can follow the mobile frame 114 of the first transfer mechanism 11 to move between the first position and the second position.

[0105] Among them, refer to Fig. 9 As shown, the roller drive motors in the second transfer mechanism 23 are all connected in transmission with the first docking gear 231, so that the first docking gear 231 can rotate under the drive of the corresponding roller drive motor; correspondingly, the roller drive motors in the second transfer mechanism 23 are connected in transmission with the second docking gear 232, so that the second docking gear 232 can rotate under the drive of the corresponding roller drive motor.

[0106] Furthermore, the roller drive motor together with the first docking gear 231 and the roller drive motor together with the second docking gear 232 in the second transfer mechanism 23 are also configured to be able to move horizontally between the docking position and the docking position. Fig. 9For example, a linear drive corresponding to the roller drive motor and the roller drive motor can be provided, and the roller drive motor and the roller drive motor can be provided at the output ends of the corresponding linear drives, so that the roller drive motor together with the first docking gear 231 and the roller drive motor together with the second docking gear 232 can independently move between the docking position and the non-docking position. The linear drive can be a conventional linear drive device such as a cylinder and an electric push rod.

[0107] Continue to refer to Fig. 9 , a driving roller 117 in the second transfer mechanism 23 is drivingly connected to a third docking gear 233 corresponding to its own first docking gear 231, and the third docking gear 233 is suitable for docking and meshing with the first docking gear 231 in the docking position; correspondingly, a roller 112 in the second transfer mechanism 23 is drivingly connected to a fourth docking gear 234 corresponding to its own second docking gear 232, wherein, when the multiple rollers 112 in the second transfer mechanism 23 are in the second position (that is, the position when the electromagnet 116 in the second transfer mechanism 23 is powered off), the fourth docking gear 234 can dock and mesh with the second docking gear 232 in the docking position.

[0108] Based on the above configuration, assuming that in the initial state, the roller drive motor together with the first docking gear 231 and the roller drive motor together with the second docking gear 232 in the second transfer mechanism 23 of the transfer assembly 10 at each of the first cargo position 21 and the second cargo position 22 are in the following positions: Fig. 9 The non-docked position shown allows the transfer assembly 10 to move normally between the storage layers 20 in the vertical direction.

[0109] When the transfer assembly 10 moves in the vertical direction to the position of any storage layer 20, the first docking gear 231 and the second docking gear 232 in the second transfer mechanism 23 at each first cargo position 21 and the second cargo position 22 on the transfer assembly 10 can be respectively aligned with the third docking gear 233 and the fourth docking gear 234 in the second transfer mechanism 23 at the corresponding cargo position in the storage layer 20.

[0110] On this basis, it is only necessary to move the roller drive motor in the second transfer mechanism 23 at each first cargo position 21 and the second cargo position 22 on the transfer component 10 together with the first docking gear 231 from the non-docking position to the docking position, so that the first docking gear 231 can be docked and meshed with the corresponding third docking gear 233, thereby realizing the transmission of the power of the roller drive motor of the second transfer mechanism 23 arranged on the transfer component 10 to the corresponding transmission roller 117 in the second transfer mechanism 23, and then the power is transmitted to the multiple rollers 111 of the corresponding second transfer mechanism 23 through the transmission roller 117, so as to realize the synchronous rotation of the multiple rollers 111 in the corresponding second transfer mechanism 23. Correspondingly, when the multiple rollers 112 in the second transfer mechanism 23 in the first cargo position 21 and the second cargo position 22 of the storage layer 20 are in the second position, and the multiple rollers 112 in the first transfer mechanism 11 on the transfer assembly 10 are also in the second position, it is only necessary to move the roller drive motor in the second transfer mechanism 23 at each first cargo position 21 and the second cargo position 22 on the transfer assembly 10 together with the second docking gear 232 from the non-docking position to the docking position, so that the second docking gear 232 can be docked and meshed with the corresponding fourth docking gear 234, thereby realizing the power transmission of the roller drive motor of the second transfer mechanism 23 arranged on the transfer assembly 10 to the multiple rollers 112 in the corresponding second transfer mechanism 23, and then realizing the synchronous rotation of the multiple rollers 112 in the corresponding second transfer mechanism 23.

[0111] It can be understood that, by adopting this method, it is only necessary to arrange a power source consisting of a drum drive motor and a roller drive motor in the second transfer mechanism 23 for the second transfer mechanism 23 at each first cargo position 21 and the second cargo position 22 on the transfer component 10, and this power source can be used as the power source for the roller 111 and the drum 112 in the second transfer mechanism 23 at the first cargo position 21 and the second cargo position 22 of each storage layer 20, thereby effectively reducing the construction and use costs of the storage unit 100.

[0112] The first docking gear 231 , the second docking gear 232 , the third docking gear 233 and the fourth docking gear 234 described in this embodiment may all be end face gears.

[0113] Example 3

[0114] On the basis of Example 2, considering that the roller drive motor and the drum drive motor are separately arranged for the second transfer mechanism 23 at the third cargo position 24, there is also a problem of high construction and use costs. To this end, this embodiment also provides another structural form of storage unit 100. Different from Example 2, this embodiment further improves the second transfer mechanism 23 at each third cargo position 24, in the hope of further reducing the construction and use costs of the storage unit 100.

[0115] Specifically, this embodiment further defines that the second transfer mechanism 23 provided at each third cargo position 24 may not include a roller drive motor and a drum drive motor.

[0116] Combination Fig.10 As shown in the content, one of the rollers 112 in the second transfer mechanism 23 at the third cargo position 24 adjacent to each first cargo position 21 is connected to one of the rollers 112 in the second transfer mechanism 23 at the corresponding first cargo position 21 through a first transmission mechanism 25; and, the rollers 112 in the second transfer mechanism 23 at the third cargo position 24 adjacent to each first cargo position 21 share a movable frame 114 with the rollers 112 in the second transfer mechanism 23 at the corresponding first cargo position 21.

[0117] For example, in this embodiment, for the second transfer mechanisms 23 at cargo positions No. 1, No. 4, and No. 6, one of the rollers 112 in the second transfer mechanism 23 at cargo position No. 1 is connected to one of the rollers 112 in the second transfer mechanism 23 at cargo position No. 4 through the first transmission mechanism 25, and one of the rollers 112 in the second transfer mechanism 23 at cargo position No. 4 is connected to one of the rollers 112 in the second transfer mechanism 23 at cargo position No. 6. In addition, at this time, the rollers 112 in the second transfer mechanisms 23 at cargo positions No. 1, No. 4, and No. 6 share a moving frame 114, so that all the rollers 112 in the second transfer mechanisms 23 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 114. Correspondingly, referring to Fig.10 As shown, for the second transfer mechanisms 23 at cargo positions No. 3, No. 5 and No. 8, one of the rollers 112 in the second transfer mechanism 23 at cargo position No. 3 is transmission-connected with one of the rollers 112 in the second transfer mechanism 23 at cargo position No. 5 through the first transmission mechanism 25, and one of the rollers 112 in the second transfer mechanism 23 at cargo position No. 5 is transmission-connected with one of the rollers 112 in the second transfer mechanism 23 at cargo position No. 8. Moreover, at this time, the rollers 112 in the second transfer mechanisms 23 at cargo positions No. 3, No. 5 and No. 8 share a moving frame 114, so that all the rollers 112 in the second transfer mechanisms 23 at cargo positions No. 3, No. 5 and No. 8 are driven by the moving frame 114 to move synchronously between the first position and the second position.

[0118] In this way, for the second transfer mechanisms 23 at the three cargo positions 1, 4 and 6, when one roller 112 in the second transfer mechanism 23 at cargo position 4 belonging to the first cargo position 21 rotates, the roller 112 in the second transfer mechanism 23 at cargo position 4 can provide the rollers 112 in the second transfer mechanisms 23 at cargo positions 1 and 6 with power to force them to rotate. Similarly, for the second transfer mechanisms 23 at the three cargo positions 3, 5 and 8, when one roller 112 in the second transfer mechanism 23 at cargo position 5 belonging to the first cargo position 21 rotates, the roller 112 in the second transfer mechanism 23 at cargo position 5 can provide the rollers 112 in the second transfer mechanisms 23 at cargo positions 3 and 8 with power to force them to rotate.

[0119] Combination Fig.11 As shown, one of the transmission rollers 117 in the second transfer mechanism 23 at the third cargo position 24 adjacent to the second cargo position 22 is connected to one of the transmission rollers 117 in the second transfer mechanism 23 at the corresponding second cargo position 22 via the second transmission mechanism 26.

[0120] For example, in this embodiment, for the second transfer mechanisms 23 at the No. 1, No. 2 and No. 3 cargo positions, one of the transmission rollers 117 in the second transfer mechanism 23 at the No. 1 cargo position is transmission-connected to one of the transmission rollers 117 in the second transfer mechanism 23 at the No. 2 cargo position through the second transmission mechanism 26, and one of the transmission rollers 117 in the second transfer mechanism 23 at the No. 2 cargo position is transmission-connected to one of the transmission rollers 117 in the second transfer mechanism 23 at the No. 3 cargo position; refer to Fig.11 As shown, for the second transfer mechanisms 23 at cargo positions 6, 7 and 8, one of the transmission rollers 117 in the second transfer mechanism 23 at cargo position 6 is transmission-connected with one of the transmission rollers 117 in the second transfer mechanism 23 at cargo position 7 through the second transmission mechanism 26, and one of the transmission rollers 117 in the second transfer mechanism 23 at cargo position 7 is transmission-connected with one of the transmission rollers 117 in the second transfer mechanism 23 at cargo position 8.

[0121] In this way, for the second transfer mechanisms 23 at the three cargo positions 1, 2 and 3, when one of the transmission rollers 117 in the second transfer mechanism 23 at cargo position 2 belonging to the second cargo position 22 rotates, the transmission roller 117 in the second transfer mechanism 23 at cargo position 2 can provide the transmission rollers 117 in the second transfer mechanisms 23 at cargo positions 1 and 3 with power to force them to rotate. Similarly, for the second transfer mechanisms 23 at the three cargo positions 6, 7 and 8, when one of the transmission rollers 117 in the second transfer mechanism 23 at cargo position 7 belonging to the second cargo position 22 rotates, the transmission roller 117 in the second transfer mechanism 23 at cargo position 7 can provide the transmission rollers 117 in the second transfer mechanisms 23 at cargo positions 6 and 8 with power to force them to rotate.

[0122] It can be understood that, by adopting the above-mentioned arrangement, combined with the contents described in Example 2, it can be seen that it is only necessary to arrange a set of power sources consisting of a drum drive motor and a roller drive motor in the second transfer mechanism 23 for the second transfer mechanism 23 at each first cargo position 21 and the second cargo position 22 on the transfer assembly 10, so as to provide the drum 112 in the second transfer mechanism 23 at the third cargo position 24 adjacent to the first cargo position 21 and the drive roller 117 in the second transfer mechanism 23 at the third cargo position 24 adjacent to the second cargo position 22 with the power required for rotation, which is beneficial to further reduce the construction and use costs of the storage unit 100.

[0123] 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 111 in the second transfer mechanism 23 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.

[0124] To this end, this embodiment further defines that the first transmission mechanism 25 and the second transmission mechanism 26 described above are both one-way transmission mechanisms. Fig.10As shown, the first transmission mechanism 25 may include a first ratchet sprocket 251, which is coaxially arranged with one of the rollers 112 of the second transfer mechanism 23 located at the first cargo position 21, and the first ratchet sprocket 251 is rotatably matched with the corresponding roller 112, that is, the first ratchet sprocket 251 can rotate relative to the corresponding roller 112, and the roller 112 coaxially arranged with the first ratchet sprocket 251 is fixedly provided with a first ratchet pawl 252 for controlling the first ratchet sprocket 251 to rotate in a single direction. One of the rollers 112 in the second transfer mechanism 23 at the third cargo position 24 adjacent to the first cargo position 21 is connected to the first ratchet sprocket 251 through a first chain 253.

[0125] Accordingly, combined Fig.11 As shown, the second transmission mechanism 26 may include a second ratchet sprocket 261, which is coaxially arranged with one of the transmission rollers 117 of the second transfer mechanism 23 located at the second cargo position 22, and the second ratchet sprocket 261 is rotationally matched with the corresponding transmission roller 117, that is, the second ratchet sprocket 261 can rotate relative to the corresponding transmission roller 117, and the transmission roller 117 coaxially arranged with the second ratchet sprocket 261 is fixedly provided with a second ratchet pawl 262 for controlling the second ratchet sprocket 261 to rotate in a single direction. One of the transmission rollers 117 in the second transfer mechanism 23 at the third cargo position 24 adjacent to the second cargo position 22 is transmission-connected to the second ratchet sprocket 261 through a second chain 263.

[0126] Among them, refer to Fig.10 or Fig.11 As shown, the first ratchet sprocket 251 and the second ratchet sprocket 261, the first pawl 252 and the second pawl 262 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.

[0127] Specifically in the embodiments of the present invention, for the second transfer mechanism 23 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 25, it can be achieved that: when all the rollers 112 in the second transfer mechanism 23 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 112 in the second transfer mechanism 23 at cargo position No. 6 can remain stationary; correspondingly, when all the rollers 112 in the second transfer mechanism 23 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 112 in the second transfer mechanism 23 at cargo position No. 1 can remain stationary.

[0128] Similarly, the principle of the second transfer mechanism 23 at cargo positions No. 3, No. 5 and No. 8 when transferring goods is the same as the principle of the second transfer mechanism 23 at cargo positions No. 1, No. 4 and No. 6 when transferring goods, and will not be elaborated here.

[0129] For the second transfer mechanism 23 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 26, it can be achieved that when all the rollers 111 in the second transfer mechanism 23 at cargo positions No. 1 and No. 2 rotate synchronously under the action of the corresponding transmission rollers 117 to transfer the goods from cargo position No. 2 to cargo position No. 1, all the transmission rollers 117 in the second transfer mechanism 23 at cargo position No. 3 can remain stationary, so that all the rollers 111 in the second transfer mechanism 23 at cargo position No. 3 remain stationary; correspondingly, when all the rollers 111 in the second transfer mechanism 23 at cargo positions No. 2 and No. 3 rotate synchronously under the action of the corresponding transmission rollers 117 to transfer the goods from cargo position No. 2 to cargo position No. 3, all the transmission rollers 117 in the second transfer mechanism 23 at cargo position No. 1 can remain stationary, so that all the rollers 111 in the second transfer mechanism 23 at cargo position No. 1 remain stationary.

[0130] Similarly, the principle of the second transfer mechanism 23 at cargo positions No. 6, 7 and 8 when transferring goods is the same as the principle of the second transfer mechanism 23 at cargo positions No. 1, 2 and 3 when transferring goods, and will not be elaborated here.

[0131] 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.
