[0044] In the intelligent warehouse, the unloading machine, the loading machine and the elevator are common transfer devices. Specifically, the goods loaded on the carrying robot are transferred to the unloading machine, and then transferred by the unloading machine and the elevator, which can be called unloading. The goods are transferred to the loading machine by the elevator, and the goods on the loading machine are transferred to the carrying robot, which can be called loading.

[0045] ​Generally, a conveying line is arranged between the unloading machine and the loading machine, and the goods unloaded by the unloading machine can be transported to the loading machine through the conveying line for transfer of the goods. The lift is one of the devices for realizing the transportation of the goods between the unloading machine and the conveying line and between the loading machine and the conveying line. Generally, the carrying robot carries the goods from, for example, a shelf, and docks with the unloading machine to transfer the goods to the unloading machine. The lift between the unloading machine and the conveying line transfers the goods on the unloading machine to the conveying line. After sorting and other operations, the lift between the loading machine and the conveying line transfers the goods from the conveying line to the loading machine, and then the goods are transferred from the loading machine again.

[0046] In this way, the logistics system at least includes one unloading machine, one loading machine and two lifts, the transfer equipment is relatively more, and the volume is relatively large, so that the occupied space of the entire logistics system is relatively large, and the equipment cost is relatively high. In addition, more manpower and material resources are required in use, assembly and maintenance, which increases the installation and maintenance cost of the logistics system.

[0047] In order to solve the above technical problems, the present application provides a logistics system and a logistics transportation method, which can effectively reduce the transfer equipment in the logistics system, reduce the cost, and save the occupied space required by the logistics system.

[0048] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more apparent and easy to understand, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0049] Figure 1 A structural schematic diagram of a logistics system provided by an embodiment of the present application is shown in Figure 2 A structural schematic diagram of a logistics transfer device provided by an embodiment of the present application is shown in Figure 3 A structural schematic diagram of a lift provided by an embodiment of the present application is shown in Figure 4 A structural schematic diagram of a lift provided by an embodiment of the present application is shown in Figure 3 A partial structural enlarged view of Figure 5 A structural schematic diagram of a lifting transfer assembly provided by an embodiment of the present application is shown in

[0050] The first aspect of the embodiments of the present application provides a logistics system, as shown in Figure 1 The logistics system includes a logistics transfer device 100 and a lift 200, and the logistics transfer device 100 includes a plurality of storage units 12 for placing goods. Specifically, as shown in Figure 2As shown, the logistics transfer device 100 can include a support 11 and a plurality of storage units 12 arranged on the support 11.

[0051] The storage unit 12 can be arranged on the support 11 in a detachable manner. The storage unit 12 can include a support frame 121 and a plurality of rolling members 122 rotatably arranged on the support frame 121. The rolling members 122 have rolling surfaces capable of rolling contact with the goods, so that the rolling members 122 can drive the goods to enter or exit the storage unit 12 through the friction generated by the rolling contact between the rolling members 122 and the goods.

[0052] The transfer direction of the goods on the storage unit 12 can be the direction in which the elevator 200 points to the logistics transfer device 100, or the direction in which the logistics transfer device 100 points to the elevator 200.

[0053] The logistics system can also include a carrying robot (not shown in the figure). The carrying robot can also carry a plurality of goods at the same time. Specifically, the carrying robot can include a body and a plurality of carrying units arranged on the body. The carrying units are connected to the storage units 12, so that the goods can be transported between the carrying robot and the logistics transfer device 100.

[0054] Referring to Figure 3 As shown, the elevator 200 includes a support frame 22, and a lifting transfer assembly 23 arranged on the support frame 22. The lifting transfer assembly 23 moves up and down relative to the support frame 22, so that the lifting transfer assembly 23 can be connected to the storage units 12 at different levels, and the goods can be transported between the lifting transfer assembly 23 and the storage units 12.

[0055] Specifically, the lifting transfer assembly has a transfer unit 232 for driving the goods to enter or exit the lifting transfer assembly 23 along the transfer direction. Specifically, referring to Figure 4 As shown, the transfer unit 232 can have a plurality of rolling conveying members 2321 arranged side by side. The rolling conveying members 2321 have rolling surfaces capable of rolling contact with the goods. The transfer unit 232 is used to transfer the goods by rolling contact between the rolling conveying members 2321 and the goods. The rolling conveying members 2321 have an included angle between the rotation shaft and the transfer direction. Specifically, the rotation shaft of the rolling conveying members 2321 can be perpendicular to the transfer direction, which facilitates the transportation of the goods. When the goods come into contact with the rolling conveying members 2321, the goods can be driven to enter or exit the lifting transfer assembly 23 by the friction between the rolling conveying members 2321 and the goods, thereby achieving the transfer of the goods.

[0056] The elevator 200 can also include a base 21, and the support frame 22 is arranged on the base 21 to ensure the stability of the elevator 200 during the movement of the lifting transfer assembly 23.

[0057] In the embodiments of the present application, the transfer direction can be the direction in which the logistics transfer device 100 points to the lifting transfer assembly 23, and the transfer direction can also be the direction in which the lifting transfer assembly 23 points to the logistics transfer device 100, that is, the goods can be transported from the storage unit 12 of the logistics transfer device 100 into the lifting transfer assembly 23, and then transported out of the lifting transfer assembly 23 by the transfer unit 232 of the lifting transfer assembly 23. Alternatively, the goods can also be transported from the lifting transfer assembly 23 into the storage unit 12.

[0058] The lifting transfer assembly 23 has a first transport end and a second transport end at two ends along the transfer direction, the first transport end can be opposite to the logistics transfer device 100, and the second transport end can be opposite to the lifting transfer assembly 23. Figure 1 As shown, the lifting transfer assembly 23 is docked with one of the storage units 12 of the logistics transfer device 100, and the goods in the storage unit 12 can enter the lifting transfer assembly 23 through the first transport end, and then be transported out of the lifting transfer assembly 23 through the second transport end under the action of the transfer unit 232.

[0059] Specifically, the side of the lifting transfer assembly 23 along the transfer direction is also used for the goods to enter the lifting transfer assembly 23, that is, the side of the lifting transfer assembly 23 along the transfer direction also has a third transport end, and the goods can enter the lifting transfer assembly 23 from the side of the lifting transfer assembly 23, and be transported out of the lifting transfer assembly 23 from the first transport end or the second transport end along the transfer direction, such as being transported out of the lifting transfer assembly 23 from the first transport end and entering the storage unit 12 of the logistics transfer device 100.

[0060] In this way, the goods can be transferred from the storage unit 12 of the logistics transfer device 100 into the lifting transfer assembly 23, and be transported out of the lifting transfer assembly 23 by the transfer unit 232, and at the same time, the goods can also enter the lifting transfer assembly 23 from the side of the lifting transfer assembly 23, and be transported into the corresponding storage unit 12 by the transfer unit 232.

[0061] That is, the logistics system realizes bidirectional transmission of the goods, and the same logistics transfer device 100 and the elevator 200 can be used for unloading, that is, the goods can be transferred from the handling robot to the logistics transfer device 100, and then transferred from the logistics transfer device 100 to the elevator 200, and transferred by the elevator 200. At the same time, it can also be used for loading, that is, the goods can enter the elevator 200 from the side of the lifting transfer assembly 23 and be transferred to the logistics transfer device 100, and then be transferred from the logistics transfer device 100 to the handling robot, effectively reducing the number of transfer equipment in the logistics system, thereby reducing the occupied space of the logistics system, saving equipment costs, and also reducing installation and maintenance costs.

[0062] In addition, when the goods are taken out from the lifting transfer assembly 23, the lifting transfer assembly 23 is empty, and the goods can enter the lifting transfer assembly 23 from the side and be transferred to the logistics transfer device 100, that is, when the lifting transfer assembly is empty, the goods can be supplemented from the side, and the transfer direction of the lifting transfer assembly is changed, the reverse transfer of the goods is realized, and it is not necessary to wait for the goods to be completely transferred from the logistics transfer device through the elevator and then change the transfer direction to realize the reverse transfer of the goods, so that the time required for unloading and loading is effectively saved, and the transfer efficiency of the goods is improved.

[0063] It can be understood that the transfer direction can be changed by changing the rotation direction of the rolling surface of the rolling conveying member 2321 in contact with the goods. Specifically, for example, the rotation direction of the rolling surface in rolling contact with the goods is from the logistics transfer device 100 to the elevator 200, and the transfer direction of the goods is from the logistics transfer device 100 to the elevator 200. The rotation direction of the rolling surface in rolling contact with the goods is from the elevator 200 to the logistics transfer device 100, and the transfer direction of the goods is that the lifting transfer assembly 23 points to the logistics transfer device 100.

[0064] Specifically, referring to Figure 3 As shown in the figure, the lifting transfer assembly 23 comprises a mounting frame 231, one side of the mounting frame 231 is movably arranged on the support frame 22, so as to realize the up-down movement of the lifting transfer assembly 23 relative to the support frame 22, and a transfer unit 232 is arranged on the mounting frame.

[0065] Referring to Figure 4 and Figure 5 As shown in the figure, first and second transport openings 2312 and 2313 can be formed at both ends of the mounting frame along the transfer direction, the first and second transport openings 2312 and 2313 are respectively located at both ends of the transfer unit along the transfer direction, and the first transport opening 2312 can be opposite to the logistics transfer device 100.

[0066] The mounting frame 231 is provided with a lateral transport opening 2311 at the side along the transfer direction, and the lateral transport opening 2311 is used for enabling the goods to enter the lifting transfer assembly 23, that is, the goods can enter the lifting transfer assembly 23 through the lateral transport opening 2311, and then be transported to the storage unit 12 of the logistics transfer device 100 through the first transport opening 2312 under the action of the transfer unit 232.

[0067] In the embodiment of the present application, referring to Figure 4 and Figure 5As shown, the transfer unit 232 comprises a connecting frame 2322, the rolling conveying member 2321 is rotatably arranged on the connecting frame 2322, and the connecting frame 2322 is further provided with two opposite guides 2323, the two guides 2323 are parallel to each other, and the guides 2323 are arranged on the inner side of the connecting frame 2322 along the transfer direction, and at least part of the guides 2323 extends above the rolling member 122.

[0068] In this way, the guides 2323 can guide and limit the goods located above the transfer unit 232, and the two guides 2323 limit the moving track of the goods on the transfer unit 232, so as to avoid the goods from deviating from the first conveying port 2312 or the second conveying port 2313 during movement and being unable to be transferred out of the lifting and transferring assembly 23. Especially when the goods enter the lifting and transferring assembly 23 from the lateral conveying port 2311 and need to be conveyed out from the first conveying port 2312, that is, there is an included angle between the entering direction and the conveying-out direction of the goods, the goods are more likely to deviate from the first conveying port 2312 during the transfer process, and the guides 2323 can better guide and limit the goods.

[0069] Figure 6 A schematic diagram of an assembly structure of an elevator and a first conveying line provided in an embodiment of the present application; Figure 7 A schematic diagram of a structure of a first conveying line provided in an embodiment of the present application.

[0070] In the embodiment of the present application, referring to Figure 6 As shown, the logistics system can further comprise a first conveying line 300, and the first conveying line 300 and the elevator 200 are butt-jointed on the side away from the logistics transfer device 100, so that the goods can be transferred between the lifting and transferring assembly 23 of the elevator 200 and the first conveying line 300.

[0071] Specifically, the goods on the logistics transfer device 100 are transferred into the lifting and transferring assembly 23, the goods in the lifting and transferring assembly 23 are conveyed out of the lifting and transferring assembly 23 under the driving of the transfer unit 232, and are conveyed to the first conveying line 300, and can be re-transferred by the first conveying line 300 for sorting and other operations.

[0072] The logistics system further comprises a second conveying line (not shown in the figure), the second conveying line comprising an inlet end and an outlet end, the inlet end being configured to supply goods to the second conveying line, and the outlet end being configured to be in lateral butt joint with the lifting transfer assembly 23, in particular, the outlet end being in butt joint with the lateral transportation port 2311, so as to transfer the goods from the second conveying line to the lifting transfer assembly 23. That is, the goods can be transported from the inlet end of the second conveying line to the outlet end of the second conveying line, and then enter the lifting transfer assembly 23 of the elevator 200 from the lateral transportation port 2311, and can be transferred to the storage unit 12 of the logistics transfer device 100 under the action of the lifting transfer unit 232.

[0073] The first conveying line 300 and the inlet end of the second conveying line can be correspondingly arranged, so that the goods can be transported from the first conveying line 300 to the second conveying line. The goods can be transferred from the storage unit 12 of the logistics transfer device 100 to the lifting transfer assembly 23 of the elevator 200, and then transferred from the lifting transfer assembly 23 to the end of the first conveying line 300 away from the elevator 200 for sorting and other operations.

[0074] The goods can also be loaded from the end of the first conveying line 300 away from the elevator 200 to the first conveying line 300, and then transported to the second conveying line, and then enter the lifting transfer assembly 23 from the lateral transportation port 2311 of the lifting transfer assembly 23, and then transferred to the storage unit 12 of the logistics transfer device 100. The end of the first conveying line 300 away from the elevator 200 and the inlet end of the second conveying line are correspondingly arranged, so that the goods can be sorted and other operations at the end of the first conveying line 300 away from the elevator 200, and the goods can also be loaded and filled for loading, which is convenient for operation.

[0075] Specifically, referring to Figure 7 The first conveying line 300 comprises a rack 301 and a plurality of rotating members 302 rotatably arranged on the rack 301, the rotating members 302 being in rolling contact with the goods, so as to drive the goods to move on the first conveying line 300 under the action of friction.

[0076] The rack 301 further comprises a first pushing unit 303, which can be arranged at the end of the rack 301 away from the elevator 200, and the first pushing unit 303 is configured to push the goods on the first conveying line 300 to the second conveying line.

[0077] Continuing to refer to Figure 7As shown, the first pushing unit 303 comprises a jacking mechanism 3031 and a pushing mechanism 3032, the pushing mechanism 3032 is arranged on the jacking mechanism 3031, the jacking mechanism 3031 can move up and down along the vertical direction perpendicular to the first conveying line 300, the jacking mechanism 3031 is used to lift the pushing mechanism 3032 above the rotating piece 302 or lower the pushing mechanism 3032 below the rotating piece 302, when the pushing mechanism 3032 is above the rotating piece 302, the pushing mechanism 3032 is used to push the goods to the second conveying line.

[0078] Specifically, when the goods do not need to be transported from the first conveying line 300 to the second conveying line, the first pushing unit 303 is below the rotating piece 302, so as to avoid affecting the contact between the goods and the rotating piece 302 and affecting the transportation of the goods.

[0079] When the goods need to be transported from the first conveying line 300 to the second conveying line, the goods are first transported to the position corresponding to the first pushing unit 303 under the action of the rotating piece 302, the jacking mechanism 3031 can lift the pushing mechanism 3032 above the rotating piece 302, then the pushing mechanism 3032 contacts the goods and lifts the goods above the rotating piece 302, and then the pushing mechanism 3032 can push the goods to the second conveying line. After the goods are pushed, the jacking mechanism 3031 lowers the pushing mechanism 3032 below the rotating piece 302, so as to avoid affecting the pushing of the next goods.

[0080] Specifically, the pushing mechanism 3032 can be located between the gaps between the adjacent two rotating pieces 302, so that the rotating piece 302 does not affect the movement of the pushing mechanism, and at the same time the pushing mechanism 3032 can better contact the goods and lift the goods.

[0081] The pushing mechanism 3032 can be one or multiple, in the embodiment of the application, the pushing mechanism 3032 is at least two, so as to ensure that the pushing mechanism 3032 can better contact the goods and push the goods to the second conveying line.

[0082] The pushing mechanism 3032 can comprise a conveying belt, the conveying belt drives the goods to move through friction, specifically, a roller set can be arranged on the jacking mechanism, the conveying belt can rotate under the drive of the roller set, when the pushing mechanism 3032 contacts the goods, the conveying belt contacts the goods, the rotating conveying belt drives the goods to move through the friction between the conveying belt and the goods, so as to push the goods to the second conveying line.

[0083] In addition, in the embodiment of the present application, the outlet end of the second conveying line can be provided with a second pushing unit, and the second pushing unit is used to push the goods on the second conveying line into the lifting transfer assembly 23. That is, the goods on the second conveying line can be pushed into the lifting transfer assembly 23 through the side of the lifting transfer assembly 23, specifically, the lateral conveying port 2311, under the action of the second pushing unit, and then transferred from the lifting transfer assembly 23 to the logistics transfer device 100, thereby further realizing the automation of the logistics system.

[0084] The structure of the second pushing unit can be the same as or different from that of the first pushing unit 303. It is only required that the goods can be pushed into the lifting transfer assembly 23 by the second pushing unit.
