The goods warehousing and outbound systems generally include an inbound conveyor line, shelves, a goods elevator, a layer-changing elevator, buffer positions, and shuttle cars, etc. Generally, one goods elevator and several buffer positions are configured on each side of each aisle. All goods are conveyed to the buffer positions by the goods elevator, and then conveyed to the shuttle cars through the buffer positions.

[0003] However, the existing buffer positions are all equipped with electric rollers, and the goods enter and exit the buffer positions through the electric rollers. A large number of electric rollers will increase the cost of the buffer positions.

Each buffer position includes a large number of electric rollers, resulting in a relatively high overall cost of the goods warehousing and outbound system.

It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. In addition, it should be noted that for the convenience of description, only parts related to the present invention are shown in the drawings, rather than all of them.

[0060] With the development of technology, the goods in-out system 1000 adopted in modern logistics operations has been gradually popularized. The continuous progress and optimization of the goods in-out system 1000 have a huge promoting effect on the development of modern logistics. The embodiments of the present disclosure provide a goods in-out system 1000.

[0061] As Figure 1 shown, the goods in-out system 1000 generally includes an inbound conveyor line 400, a shelf 200, a goods elevator 100, a layer-changing elevator (not shown in the figure), a buffer position 500, a shuttle car 300, etc.

[0062] Among them, as Figure 1 and Figure 2 shown, the shelf 200 is provided with at least two groups. The at least two groups of shelves 200 are arranged at intervals in the left-right direction (the first direction), and a lane 600 is formed between two adjacent groups of shelves 200. Generally, one goods elevator 100 and several buffer positions 500 are arranged on one side of each lane 600. Buffer positions 500 are arranged on each layer of the shelf 200. All goods 2000 are conveyed to the buffer positions 500 through the goods elevator 100, and then conveyed to the shuttle car 300 through the buffer positions 500.

[0063] As Figure 2As shown, each shelf 200 includes shelf guide rails 230 extending in the front-rear direction (the second direction). Two shelf guide rails 230 at the same roadway 600 position can jointly support the shuttle car 300, and the shuttle car 300 can move along the shelf guide rails 230, so as to realize the picking and placing of goods 2000 at different positions of the shelf 200.

[0064] As Figures 1 to 4 shown, the shelf 200 further includes support columns 210, a rear beam 220 and cross beams 250. The support columns 210 extend in the up-down direction and are provided in multiple numbers. An installation space is formed between the multiple support columns 210. The rear beam 220, the cross beams 250 and the shelf guide rails 230 are arranged at the installation space position. The rear beam 220 and the shelf guide rails 230 each extend in the front-rear direction and are fixedly connected to the corresponding support columns 210, and the rear beam 220 and the shelf guide rails 230 are arranged at intervals in the left-right direction.

[0065] As Figure 3 and Figure 4 shown, the cross beams 250 are provided in multiple numbers and are arranged at intervals in the front-rear direction. Each cross beam 250 extends in the left-right direction. One end of each cross beam 250 is fixedly connected to the rear beam 220, and the other end of each cross beam 250 is fixedly connected to the shelf guide rails 230. The buffer positions 500 are arranged on the cross beams 250. The arrangement of the cross beams 250 can realize the stable support for the buffer positions 500. In addition, the overall volume and weight of all the cross beams 250 are relatively small compared with a whole steel plate. Therefore, the cross beams 250 in the embodiments of the present disclosure can realize the lightweight design of the goods inbound and outbound system 1000. Specifically, the inside of the cross beam 250 can adopt a hollow design, which can realize greater strength and hardness of the cross beam 250 while ensuring a smaller weight of the cross beam 250, effectively realizing the lightweight design of the cross beam 250.

[0066] As Figure 2 shown, the shelf 200 further includes a transition plate 240. The shelf guide rails 230 and the buffer positions 500 are arranged at intervals in the left-right direction. The transition plate 240 is arranged between the shelf guide rails 230 and the buffer positions 500. When the goods 2000 are transmitted between the shelf guide rails 230 and the buffer positions 500, it can prevent the goods 2000 from getting stuck in the gap between the shelf guide rails 230 and the buffer positions 500, ensure the smooth transmission of the goods 2000 between the shuttle car 300 and the buffer positions 500, prevent the goods 2000 from being damaged, and ensure better quality of the goods 2000.

[0067] In addition, as Figure 2As shown, the inbound conveyor line 400, the goods elevator 100, and the buffer position 500 are arranged in sequence from back to front. The inbound conveyor line 400 can receive the goods 2000 entering the goods inbound and outbound system 1000. The inbound conveyor line 400 cooperates with the goods elevator 100 to realize the transmission of the goods 2000 between the inbound conveyor line 400 and the goods elevator 100.

[0068] As Figure 2 shown, both the inbound conveyor line 400 and the goods elevator 100 include a plurality of electric rollers. The electric rollers extend in the left - right direction, and the plurality of electric rollers are arranged at intervals in the front - back direction. Through the arrangement of the plurality of electric rollers, the transmission of the goods 2000 between the inbound conveyor line 400 and the goods elevator 100 can be realized.

[0069] As Figure 2 shown, the existing buffer positions 500 are all equipped with electric rollers. Through the cooperation of the electric rollers of the buffer position 500 and the electric rollers of the goods elevator 100, the goods 2000 can enter and exit the buffer position 500. A large number of electric rollers will increase the costs of the buffer position 500 and the goods inbound and outbound system 1000.

[0070] To solve the above problems, as Figure 5 shown, the goods elevator 100 includes a load - carrying platform assembly 20. The load - carrying platform assembly 20 includes a load - carrying platform frame 21, a bearing mechanism 23, and a handling mechanism 22. The bearing mechanism 23 and the handling mechanism 22 are arranged on the load - carrying platform frame 21. The bearing mechanism 23 is used for bearing and conveying the goods 2000. The handling mechanism 22 can independently transmit the goods 2000 between the bearing mechanism 23 and the buffer position 500. Without the cooperation of the goods elevator 100 and the buffer position 500, the transmission of the goods 2000 between the bearing mechanism 23 and the buffer position 500 can be realized. Compared with the existing buffer position 500 with electric rollers, the buffer position 500 in the embodiment of the present disclosure cancels the electric rollers, and the buffer position 500 only needs to realize the supporting function for the goods 2000, which can simplify the structure of the buffer position 500 and effectively reduce the costs of the buffer position 500 and the goods inbound and outbound system 1000.

[0071] In an optional embodiment, as Figure 5 and Figure 6 shown, the handling mechanism 22 and the bearing mechanism 23 are arranged from top to bottom, which can realize the modular design of the load - carrying platform assembly 20 and realize the compact arrangement of the handling mechanism 22 and the bearing mechanism 23 in a limited space.

[0072] As Figure 3 and Figure 4As shown, the buffer position 500 includes a support plate 510. The support plate 510 is plate-shaped and is disposed on the cross beam 250 and fixedly connected to the cross beam 250. The support plate 510 can effectively support the goods 2000. Exemplarily, the support plate 510 can be a metal plate structure such as a steel plate or an iron plate. The metal plate structure has relatively high strength and hardness to achieve a better stable support effect of the support plate 510 on the goods 2000.

[0073] As Figure 2 and Figure 4 shown, the buffer position 500 can carry at least two goods 2000 arranged in sequence in the front-rear direction at the same time. The shuttle car 300 can pick up goods at at least two positions simultaneously, improving the transmission efficiency of the goods 2000 in the entire goods in-out storage system 1000.

[0074] In an alternative embodiment, as Figure 3 and Figure 4 shown, the buffer position 500 further includes a reflector 520. The load carrier assembly 20 includes a detection device. The reflector 520 and the detection device (not shown in the figure) cooperate to effectively identify whether there are goods 2000 on this layer of the support plate 510. The detection device is electrically connected to the controller (not shown in the figure) of the goods in-out storage system 1000. The detection device can transmit the signal of whether there are goods 2000 to the controller, facilitating the controller to effectively and accurately control the overall working state of the goods in-out storage system 1000 in combination with this signal.

[0075] It should be noted that the structure of the detection device is complex and the cost is high. In this alternative embodiment, a reflector 520 with a lower cost is provided at each layer of the buffer position 500, and only one detection device is provided on the load carrier assembly 20. It can not only accurately judge whether there are goods 2000 on each layer of the buffer position 500, but also effectively reduce the cost of the goods in-out storage system 1000.

[0076] Exemplarily, as Figure 3 and Figure 4As shown, the reflector 520 can be a reflecting mirror. The detection device can emit and receive signals in the front-back direction. When the loading platform assembly 20 is directly opposite to the buffer position 500, the detection device and the reflector 520 are arranged in the front-back direction, and the goods 2000 can be buffered in the space between the detection device and the reflector 520. Specifically, if there is no goods 2000 on the support plate 510, the signal emitted by the detection device is reflected by the reflecting mirror and then received by the detection device again, so that the detection device can determine that there is no goods 2000 on the support plate 510; if there is goods 2000 on the support plate 510, the signal emitted by the detection device hits the goods 2000 and the signal cannot be reflected back to the detection device again, so that the detection device can determine that there is goods 2000 on the support plate 510. Exemplarily, the detection device can be a laser transmitter-receiver, etc. Since the laser transmitter-receiver is a relatively common structure in the art, the specific structure of the laser transmitter-receiver will not be elaborated in the embodiments of the present disclosure.

[0077] In an alternative embodiment, as Figure 3 and Figure 4 shown, each reflector 520 and the corresponding detection device form a set of detection components. Two sets of detection components are provided and arranged at intervals in the left-right direction. As long as one set of detection components can detect that there is goods 2000 on the support plate 510, it can be determined that there is goods 2000 on the support plate 510, avoiding the missed detection of goods 2000 caused by only setting one set of detection components.

[0078] In an alternative embodiment, the number of sets of detection components can also be three sets, four sets, five sets, etc. Setting a relatively large number of detection components in a limited space can achieve accurate judgment on whether there is goods 2000 on the support plate 510.

[0079] Combined with Figure 1 、 Figure 7 and Figure 8 to illustrate the overall structure of the goods elevator 100, as Figure 1 、 Figure 7 and Figure 8 shown, the goods elevator 100 includes a column 10, a loading platform assembly 20, and a lifting drive mechanism 30. The column 10 extends in the up-down direction. The column 10 and the buffer position 500 are arranged in the front-back direction. The loading platform assembly 20 is arranged on the column 10. The lifting drive mechanism 30 can drive the loading platform assembly 20 to move in the up-down direction so as to adjust the position of the loading platform assembly 20 in the up-down direction, thereby realizing the alignment of the loading platform assembly 20 with the buffer positions 500 on different floors, and thus realizing the transfer of goods 2000 between the loading platform assembly 20 and the buffer positions 500 on different floors.

[0080] Combined with Figure 7The specific structure of the lifting drive mechanism 30 will be described. For example, Figure 7 As shown, the lifting drive mechanism 30 includes a lifting motor 310, a driving wheel (not shown in the figure), a driven wheel 320, and an annular belt 330. The driving wheel and the driven wheel 320 are arranged in the up-and-down direction and are both pivotally connected to the column 10. The annular belt 330 is disposed around the outer peripheries of the driving wheel and the driven wheel 320 and is jointly tensioned by the driving wheel and the driven wheel 320. The load platform assembly 20 is fixed to the annular belt 330. The lifting motor 310 can drive the driving wheel to rotate, and the driving wheel rotates to drive the annular belt 330 and the driven wheel 320 to rotate, thereby realizing the up-and-down lifting of the load platform assembly 20.

[0081] In an alternative embodiment, the lifting drive mechanism 30 can also be a lead screw-nut lifting assembly, which can also realize the up-and-down lifting of the load platform assembly 20. Since the lead screw-nut lifting assembly is a relatively common structure in the art, this alternative embodiment will not be specifically introduced. Of course, all drive mechanisms that can realize the up-and-down lifting of the load platform assembly 20 are within the protection scope of this alternative embodiment.

[0082] Combined with Figures 6 to 7 The structure of the load platform frame 21 will be described. For example, Figures 6 to 7 As shown, the load platform frame 21 includes two side frames 211, a bottom frame 213, and a connecting beam 214. The two side frames 211 are arranged at intervals in the left-right direction. The bottom frame 213 is disposed between the two side frames 211 and is fixedly connected to the side frames 211. The connecting beam 214 is disposed between the two side frames 211 and is fixedly connected to the side frames 211. The connecting beam 214 is disposed above the bottom frame 213. The two side frames 211, the bottom frame 213, and the connecting beam 214 jointly form a receiving space for receiving the handling mechanism 22 and the bearing mechanism 23. The structure of the load platform frame 21 is stable, and the load platform frame 21 can stably support the handling mechanism 22 and the bearing mechanism 23.

[0083] In an alternative embodiment, as Figure 8 shown, the load platform frame 21 further includes a plurality of limiting wheels 212. The plurality of limiting wheels 212 are pivotally connected to one of the side frames 211. The plurality of limiting wheels 212 respectively abut against different sides of the column 10. The plurality of limiting wheels 212 cooperate with the column 10 to achieve a better limiting effect on the load platform assembly 20 in the horizontal plane, ensure that the load platform assembly 20 moves smoothly in the up-and-down direction, prevent the load platform assembly 20 from deflecting in the horizontal plane, avoid jamming problems between the load platform assembly 20 and the column 10, and realize smooth adjustment of the position of the load platform assembly 20 in the up-and-down direction.

[0084] Combined with Figures 5 to 9 The structure of the handling mechanism 22 will be described. For example, Figures 5 to 9As shown, the handling mechanism 22 includes a fork-out driving mechanism 223 and two telescopic forks 221. The two telescopic forks 221 are arranged oppositely in the left-right direction. The telescopic fork 221 includes a back plate 2211 and a protruding plate 2212. The fork-out driving mechanism 223 can drive the protruding plate 2212 to telescopically extend in the front-back direction. Through the setting of the telescopic fork 221, the transfer of the goods 2000 between the buffer position 500 and the loading platform assembly 20 can be realized.

[0085] In an alternative embodiment, the handling mechanism 22 can also be a four-axis robotic arm, a six-axis robotic arm, etc. All mechanisms that can independently transfer the goods 2000 between the loading mechanism 23 and the buffer position 500 are within the protection scope of this alternative embodiment. This alternative embodiment does not specifically limit the specific type of the handling mechanism 22.

[0086] As Figures 6 to 10 shown, the fork-out driving mechanism 223 includes a first motor 2231 and a transmission component. The output shaft of the first motor 2231 is in transmission connection with the protruding plate 2212 through the transmission component, with a simple structure and easy to manufacture. Specifically, as Figure 6 and Figure 10 shown, the output shaft of the first motor 2231 extends in the left-right direction. Through the setting of the transmission component, the first motor 2231 and the protruding plate 2212 can be arranged in the left-right direction, thereby effectively reducing the size of the loading platform assembly 20 in the front-back direction and realizing the rational layout of the goods in-out system 1000 in a limited space.

[0087] Specifically, as Figure 9 and Figure 10As shown, the transmission assembly includes a rack 2236 and a pulley assembly 2232. The rack 2236 extends in the front-rear direction and is fixedly connected to the extending plate 2212. The pulley assembly 2232 includes a driving wheel 22323, an idler wheel 22321, and an endless toothed belt 22324. The driving wheel 22323 and the idler wheel 22321 are pivotally connected to the back plate 2211. The endless toothed belt 22324 is disposed around the outer peripheries of the driving wheel 22323 and the idler wheel 22321 and is jointly tensioned by the driving wheel 22323 and the idler wheel 22321. The endless toothed belt 22324 includes engaging teeth 223241, which are located outside the endless toothed belt 22324. The engaging teeth 223241 are engaged with the rack 2236. The driving wheel 22323 is directly connected or transmission-connected to the output shaft of the first motor 2231. When the first motor 2231 operates, the first motor 2231 drives the driving wheel 22323 and the endless toothed belt 22324 to rotate. The endless toothed belt 22324 can drive the rack 2236 to move in the front-rear direction, thereby realizing the telescopic movement of the extending plate 2212 in the front-rear direction, and thus realizing the transmission of the goods 2000 in the front-rear direction. The transmission assembly of this structure can reduce the impact and vibration during operation. The transmission assembly operates smoothly and noiselessly during the working process. It has a simple structure, is easy to manufacture, is convenient for installation and maintenance, and has a low cost.

[0088] As Figure 10 shown, the fork-out driving mechanism 223 further includes a mounting bracket 2235. The mounting bracket 2235 is disposed on the back plate 2211, and the first motor 2231 is disposed on the mounting bracket 2235. Through the setting of the mounting bracket 2235, on the one hand, it can achieve a stable supporting effect on the first motor 2231; on the other hand, the setting of the mounting bracket 2235 facilitates the quick installation of the first motor 2231.

[0089] As Figure 9 shown, the transmission assembly further includes a tensioning wheel 22322. The tensioning wheel 22322 abuts against the endless toothed belt 22324. The tensioning wheel 22322 is disposed on the back plate 2211 and its relative position with the back plate 2211 is adjustable to tension the endless toothed belt 22324. When the transmission assembly becomes loose after a long period of use, by adjusting the relative position of the tensioning wheel 22322 and the back plate 2211, an effective tensioning effect on the endless toothed belt 22324 can be achieved, ensuring that the transmission assembly always has a good power transmission effect.

[0090] As Figure 10 shown, the transmission assembly further includes a transmission shaft 2234. The driving wheels 22323 on the two telescopic forks 221 are coaxially arranged and are both connected to the transmission shaft 2234. Through the setting of one first motor 2231, the driving wheels 22323 on the two telescopic forks 221 can be simultaneously driven to move. The fork-out driving mechanism 223 includes fewer components, has a simple structure, and occupies a small space. In an optional embodiment, asFigure 10 As shown, the transmission shaft 2234 is a spline shaft, which is connected to the driving wheel 22323. The spline shaft can better transmit the torque of the first motor 2231 to the driving wheel 22323, realizing the output of a larger torque of the driving wheel 22323, avoiding relative rotation between the driving wheel 22323 and the transmission shaft 2234, and avoiding the problem of slipping between the driving wheel 22323 and the transmission shaft 2234.

[0091] As Figure 9 shown, the transmission assembly further includes a support member 22325. The support member 22325 extends in the front-rear direction. The support member 22325 is disposed inside the annular toothed belt 22324 and abuts against the annular toothed belt 22324, so that the meshing teeth 223241 mesh with the rack 2236, thereby realizing the stable meshing of the meshing teeth 223241 and the rack 2236, and ensuring the stable transmission of power between the meshing teeth 223241 and the rack 2236.

[0092] An alternative embodiment, as Figure 9 shown, the support member 22325 is connected to the back plate 2211, and the relative position of the support member 22325 and the back plate 2211 in the up-down direction is adjustable. By adjusting the position of the support member 22325, the meshing teeth 223241 and the rack 2236 can always be stably meshed. Exemplarily, the support member 22325 and the back plate 2211 can be connected by screws, pins, magnetic attraction components, buckles, etc. The embodiments of the present disclosure do not specifically limit the connection manner between the support member 22325 and the back plate 2211. All connection manners that can realize the adjustment of the relative position between the support member 22325 and the back plate 2211 are within the protection scope of the embodiments of the present disclosure.

[0093] As Figure 9 shown, the telescopic fork 221 further includes a guiding component 2214. The guiding component 2214 is disposed between the back plate 2211 and the extending plate 2212, and the guiding component 2214 can guide the extending plate 2212, so that the extending plate 2212 moves in the front-rear direction, avoiding deflection of the extending plate 2212 during the telescopic process and avoiding jamming problems of the extending plate 2212 during the movement process.

[0094] Exemplarily, as Figure 9As shown, the guiding component 2214 includes a slide rail 22141 and a chute member 22142. One of the slide rail 22141 and the chute member 22142 is arranged on the back plate 2211, and the other is arranged on the extending plate 2212. The slide rail 22141 extends in the front-rear direction. A chute 221421 extending in the front-rear direction is formed on the chute member 22142. The slide rail 22141 is inserted into the chute 221421 and can slide along the chute 221421. The structure is simple and convenient for assembly.

[0095] As Figure 9 shown, the telescopic fork 221 further includes a fork component 2213. The fork component 2213 includes a fork 22131 and a fork driving mechanism 22132. The fork driving mechanism 22132 includes a main shaft that extends in the front-rear direction. The fork 22131 is fixedly connected to the main shaft. The fork driving mechanism 22132 can drive the fork 22131 to switch between the lowered state and the retracted state. When the fork 22131 is in the lowered state, the fork 22131 can drive the goods 2000 to move.

[0096] As Figure 9 shown, the fork component 2213 is provided with at least two groups. The at least two groups of fork components 2213 are arranged at intervals in the front-rear direction. Therefore, the telescopic fork 221 can drive multiple goods 2000 to move simultaneously, improving the transmission efficiency of the goods 2000. In addition, through the arrangement of at least two groups of fork components 2213, the two-way movement of the goods 2000 between the handling mechanism 22 and the buffer position 500 can be realized, and the flexibility of the overall application scenario is relatively high.

[0097] Exemplarily, when the fork 22131 is in the lowered state, adjacent two forks 22131 of the same telescopic fork 221 form an accommodating space, and each accommodating space can accommodate a single good 2000.

[0098] As Figure 5 and Figure 11 shown, the handling mechanism 22 further includes a variable-spacing driving mechanism 224. The variable-spacing driving mechanism 224 is used to move two telescopic forks 221 closer to or farther away from each other, so as to achieve the variable-spacing effect of the two telescopic forks 221, and thus realize the adaptation of the handling mechanism 22 to goods 2000 of different widths. The versatility is stronger, and it can adapt to different types of goods 2000, effectively reducing the manufacturing cost of the goods storage and retrieval system 1000.

[0099] Exemplarily, as Figure 11As shown, the variable pitch drive mechanism 224 includes a lead screw 2242, a nut 2243, and a second motor 2241. The lead screw 2242 extends in the front-to-back direction and is pivotally connected to the cargo platform frame 21. The nut 2243 is threadedly connected to the lead screw 2242 and fixedly connected to one of the telescopic forks 221. The second motor 2241 can drive the lead screw 2242 to rotate. The rotation of the lead screw 2242 drives the nut 2243 to move in the left-right direction, and the nut 2243 drives the telescopic forks 221 to move in the left-right direction, thereby achieving a variable pitch effect for the two telescopic forks 221. In addition, the cooperation between the lead screw 2242 and the nut 2243 can enable the variable pitch drive mechanism 224 to achieve precise and stable transmission effects.

[0100] An optional embodiment, such as Figure 11 As shown, the variable pitch drive mechanism 224 further includes a transmission mechanism 2246, the second motor 2241 and the lead screw 2242 are arranged in the front-to-back direction, and the output shaft of the second motor 2241 is connected to the lead screw 2242 through the transmission mechanism 2246, thereby effectively reducing the size of the cargo platform assembly 20 in the front-to-back direction. Figure 11 As shown, the transmission mechanism 2246 includes an active transmission wheel 22461, a driven transmission wheel 22462, an annular transmission belt 22463 and a fixing frame 22464. The second motor 2241 is connected to the back plate 2211 through the fixing frame 22464. The active transmission wheel 22461 is coaxially fixed with the output shaft of the second motor 2241. The active transmission wheel 22461 is coaxially fixed with the lead screw 2242. The annular transmission belt 22463 is arranged around the outer circumference of the active transmission wheel 22461 and the driven transmission wheel 22462 and is jointly tensioned by the active transmission wheel 22461 and the driven transmission wheel 22462. The second motor 2241 drives the active transmission wheel 22461 to rotate, the active transmission wheel 22461 drives the driven transmission wheel 22462 and the annular transmission belt 22463 to rotate, and the driven transmission wheel 22462 can drive the lead screw 2242 to rotate.

[0101] An optional embodiment, such as Figure 11 As shown, the variable pitch drive mechanism 224 also includes a guide shaft 2244 and a guide sleeve 2245. The guide shaft 2244 is fixedly connected to the cargo platform frame 21 and extends in the left and right directions. The guide sleeve 2245 is arranged on the movable telescopic fork 221. The guide sleeve 2245 is inserted into the guide shaft 2244 and can move along the guide shaft 2244. The cooperation between the guide shaft 2244 and the guide sleeve 2245 can achieve a better guiding effect on the left and right movement of the telescopic fork 221.

[0102] In an optional embodiment, if Figure 11As shown, the guide shaft 2244 and the guide sleeve 2245 are provided in at least two groups. The provision of at least two groups of guide shafts 2244 and guide sleeves 2245 can prevent the telescopic fork 221 from rotating during the movement in the left and right directions.

[0103] For ease of understanding, combined Figures 5 to 11 The working principle of the cargo platform assembly 20 is explained. The cargo platform assembly 20 has two important working modes. One mode is the transportation of the cargo 2000 by the cargo platform assembly 20, and the other mode is the variable distance mode of the cargo platform assembly 20.

[0104] Combine Figure 6 The structure of the carrying mechanism 23 is described as follows. Figure 6 As shown, the carrying mechanism 23 includes a third motor (not shown), a frame 231, and at least two conveyor rollers 232. The at least two conveyor rollers 232 are pivotally connected to the frame 231 and spaced apart in the front-to-back direction. The conveyor rollers 232 extend in the left-to-right direction, and the third motor can drive the conveyor rollers 232 to rotate. The rotation of the conveyor rollers 232, in conjunction with the motorized rollers of the inbound conveyor line 400, enables the transfer of the goods 2000 between the inbound conveyor line 400 and the cargo elevator 100.

[0105] like Figure 6 As shown, the supporting mechanism 23 also includes an annular conveyor belt 233, and two adjacent conveyor rollers 232 are connected by the annular conveyor belt 233. Only one third motor is required to realize the synchronous rotation of all conveyor rollers 232. The supporting mechanism 23 has a simple structure, occupies a small space, is low in cost and is easy to manufacture.

[0106] Regarding the mode of transporting the cargo 2000 by the cargo platform assembly 20, as shown in FIG. Figures 5 to 10 As shown, the required fork drive mechanism 22132 drives the corresponding fork 22131 to be lowered, and the unnecessary fork drive mechanism 22132 drives the corresponding fork 22131 to be retracted, and the first motor 2231 works, and the first motor 2231 drives the driving wheel 22323 and the annular toothed belt 22324 to rotate, and the annular toothed belt 22324 can drive the rack 2236 to move in the front and rear directions, thereby realizing the telescopic movement of the extension plate 2212 in the front and rear directions, and the fork 22131 drives the cargo 2000 to move in the front and rear directions.

[0107] For the variable distance mode of the cargo platform assembly 20, such as Figure 5 、 Figure 6 and Figure 11As shown, the second motor 2241 can drive the lead screw 2242 to rotate. The rotation of the lead screw 2242 drives the nut 2243 to move in the left-right direction, and the nut 2243 drives the telescopic fork 221 to move in the left-right direction, thereby realizing the variable pitch effect of the two telescopic forks 221, and thus realizing the adaptation to goods 2000 of different models.
