Detailed ways

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 below in combination with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the 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.

The technical solutions disclosed in various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

Please refer to FIG. 1 to FIG. 18 , an embodiment of the present invention discloses a transport trolley, and the disclosed transport trolley includes a carrying platform 100 and a lifting and transporting mechanism 200 .

The loading platform 100 is a basic component of the AGV vehicle, and the loading platform 100 includes basic functional components of the AGV vehicle, such as a mobile driving mechanism, etc. Specifically, the loading platform 100 includes a first driving motor that drives the entire transport vehicle to move.

The lifting and transporting mechanism 200 is arranged on the loading platform 100. The lifting and transporting mechanism 200 can be lifted and moved in the height direction of the transporting trolley. The lifting and transporting mechanism 200 is used to realize the transport of goods, that is, to realize the picking and placing of goods on the shelf. The lifting and moving of the lifting and transporting mechanism 200 can realize the picking and placing of goods placed at different heights on the shelf B. Usually, the goods are packed in the cargo box A, and the lifting and transporting mechanism 200 realizes the transport of the goods by carrying the cargo box A.

The carrying platform 100 is the foundation of the transport trolley, ensuring the movement of the entire transport trolley. The carrying platform 100 provides an installation foundation for other components of the transport trolley. The lifting and transporting mechanism 200 is arranged on the carrying platform 100 and can be lifted and lowered in the height direction of the transport trolley.

In this embodiment, the lifting and transporting mechanism 200 includes a lifting base 210 and a transporting body 220. The lifting base 210 is a basic component of the lifting and transporting mechanism 200, and also provides an installation basis for the transporting body 220. The lifting base 210 is connected to the carrying platform 100, and the transporting body 220 is connected to the lifting base 210, thereby realizing the installation of the transporting body 220.

The transport body 220 includes a support platform 221 and two telescopic mechanisms 222 arranged on both sides of the support platform 221, and the two telescopic mechanisms 222 can be connected to the support platform 221 through a distance adjustment mechanism 223. The two telescopic mechanisms 222 and the support platform 221 form a storage space 224, and the storage space 224 can accommodate a cargo box A containing goods, and is then supported by the support platform 221. The distance adjustment mechanism 223 is connected to the two telescopic mechanisms 222, and can adjust the two telescopic mechanisms 222 to be closer to or farther away from each other, and can adjust the distance between the two telescopic mechanisms 222. The distance between the two telescopic mechanisms 222 is adjusted, and the size of the storage space 224 can eventually be changed. The distance adjustment mechanism 223 can be a hydraulic telescopic member or a pneumatic telescopic member that can be telescopic at both ends, and the two telescopic mechanisms 222 can be arranged at both ends of the hydraulic telescopic member or the pneumatic telescopic member. Of course, the distance adjustment mechanism 223 can also be other mechanisms, and the present application does not limit the specific type of the distance adjustment mechanism 223.

In this embodiment, the telescopic mechanism 222 includes a telescopic body 2221 and a cargo lever 2222, and the telescopic body 2221 includes a telescopic portion 2221b. The cargo lever 2222 is rotatably disposed at the end of the telescopic portion 2221b, and the cargo lever 2222 can be rotated toward the cargo, and thus be in a position to move the cargo box. When the cargo lever 2222 is in a position to move the cargo box A, the telescopic body 2221 can be extended and retracted to enable the cargo lever 2222 to drive the cargo box A to move, thereby achieving the purpose of transferring the cargo.

In a preferred solution, both ends of the telescopic part 2221b are provided with cargo levers 2222. The cargo lever 2222 is usually connected to the second drive motor 2223 installed on the telescopic body 2221, and can be rotated under the drive of the second drive motor 2223, so that the cargo lever 2222 switches between the working position and the avoidance position. During the operation, the telescopic part 2221b of the telescopic body 2221 is telescopic, and can drive the cargo lever 2222 at its end to move. It should be noted that the working position of the cargo lever 2222 refers to the position where the cargo lever 2222 is rotated to move the cargo box A, and can push the cargo box A to move under the telescopic drive of the telescopic part 2221b. The avoidance position of the cargo lever 2222 refers to the position where the cargo lever 2222 is rotated to avoid the cargo box A, and will not interfere with the cargo box A in the telescopic direction of the telescopic body 2221.

For ease of understanding, the transporting process of the lifting and transporting mechanism 200 is now described in detail by taking an example in which both ends of the telescopic portion 2221b are provided with cargo shifting rods 2222 .

The process of picking up cargo box A from the shelf and transporting it to the transport cart is as follows: Please refer to Figures 3-7 and 13-16. The transport cart moves to the shelf, determines the size of the cargo box according to the task, and the distance adjusting mechanism 223 adjusts the distance between the two telescopic mechanisms 222 according to the size of the cargo box (if the cargo box size is larger, the distance between the two telescopic mechanisms 222 is larger, and if the cargo box size is smaller, the distance between the two telescopic mechanisms 222 is smaller). At the same time, the telescopic part 2221b of the telescopic mechanism 222 is extended to the appropriate position on the shelf, and then the cargo lever 2222 is rotated to the working position, and then the telescopic parts 2221b of the two telescopic mechanisms 222 are simultaneously contracted, so that the cargo lever 2222 located at the front end of the extension direction drives the cargo box to move to the support platform 221, and finally completes the transfer of the cargo box from the shelf to the transport cart.

Of course, when the cargo box A is located on the support platform 221, the cargo lever 2222 rotates to the working position, and during the extension of the telescopic mechanism 222, the cargo lever 2222 located at the rear end of the extension direction can drive the cargo box to be transferred from the support platform 221 to the shelf, and finally complete the transfer of the cargo box from the support platform 221 to the shelf. It can be seen from the above working process that in the transport cart disclosed in the embodiment of the present invention, the support platform 221 and the two telescopic mechanisms 222 form a storage space 224, and the distance adjustment mechanism 223 can adjust the distance between the two telescopic mechanisms 222, so that the storage space 224 can adapt to the placement of cargo boxes of different sizes, and finally enable the transport cart to transport cargo boxes of different sizes. In this case, the storage system does not need to be equipped with multiple types of transport carts, thereby reducing the cost of the storage system.

Of course, when only one end of the telescopic part 2221b is provided with a cargo lever 2222, the orientation of the transport cart can be adjusted so that one cargo lever 2222 can drive the cargo box A from the shelf B to the transport cart, and can also drive the cargo box A from the transport cart to the shelf B.

In this embodiment, the distance adjusting mechanism 223 is used to adjust the distance between the two telescopic mechanisms 222. When the transport trolley does not include the distance adjusting mechanism 223, the two telescopic mechanisms 222 can be connected to the support platform 221, and the distance between the two telescopic mechanisms 222 is determined. In this case, the transport body 220 can only transport cargo boxes of a determined size.

Please refer to Figure 1 again. The telescopic body 2221 may include a fixed portion 2221a, a telescopic portion 2221b and a driving portion. The telescopic portion 2221b is movably arranged on the fixed portion 2221a to achieve telescopic. The driving portion is connected to the telescopic portion 2221b and can drive the telescopic portion 2221b to move relative to the fixed portion 2221a. In a preferred embodiment, the driving portion can drive the telescopic portion 2221b to extend from one end of the fixed portion 2221a, and can also drive the telescopic portion 2221b to extend from the other end of the fixed portion 2221a, so as to be able to telescope in the directions of both sides of the transport trolley. In this case, the transport trolley has the ability to pick up and place cargo boxes A on the shelves B on both sides thereof.

In order to further optimize the above technical solution, in a preferred solution, the transport body 220 can be connected to the lifting base 210 through a swivel mechanism 230, and the swivel mechanism 230 can realize the rotation of the transport body 220 relative to the lifting base 210, so as to adjust the orientation of the storage space 224, thereby enabling the transport body 220 to more flexibly transfer the cargo box. In this embodiment, the swivel mechanism 230 plays the role of an intermediate connection, and can realize the rotation of the transport body 220 relative to the lifting base 210. There can be many types of swivel mechanisms 230, for example, the swivel mechanism 230 can be a bearing.

In order to improve the handling capacity of the transport trolley, in a preferred solution, the transport trolley disclosed in the embodiment of the present invention may further include a vehicle-mounted shelf 300. The vehicle-mounted shelf 300 is arranged on the loading platform 100 and has the ability to store cargo boxes. The transport trolley disclosed in the embodiment of the present invention may further include a lifting drive mechanism, the lifting and transporting mechanism 200 is movably arranged on the vehicle-mounted shelf 300, the lifting drive mechanism is connected to the lifting and transporting mechanism 200, and the lifting drive mechanism is used to drive the lifting and transporting mechanism 200 to rise and fall along the vehicle-mounted shelf 300. Usually, the vehicle-mounted shelf 300 is provided with a multi-layer structure in the height direction, and each layer can be used to place cargo boxes.

In this embodiment, the vehicle-mounted shelf 300 may include a storage compartment 310, the lifting base 210 may be provided with an escape opening 211, the escape opening 211 may connect the storage space 224 and the storage compartment 310, and the telescopic mechanism 222 may extend into the storage compartment 310. The telescopic mechanism 222 can extend into the storage compartment 310, thereby enabling the cargo box to be transferred between the storage space 224 and the storage compartment 310.

As described above, the transport trolley may include a vehicle-mounted shelf 300. In a specific embodiment, the vehicle-mounted shelf 300 may include at least two columns 320 and a plurality of storage compartments 310 distributed along the height direction of the columns 320. There are various structures for forming the storage compartments 310. In a specific embodiment, the columns 320 are provided with a plurality of pairs of partitions 330 along their height direction. In the height direction of the columns 320, a storage compartment 310 may be formed between two adjacent pairs of partitions 330. The telescopic portion 2221b of the telescopic mechanism 222 may extend into the storage compartment 310, thereby realizing the transfer of the cargo box.

In order to facilitate the cargo box to enter the storage compartment without deflection, in a preferred solution, a guide member 340 is provided on the same pair of partitions 330, and a guide space is formed between the ends of the guide members 340 of the same pair of partitions 330 close to the avoidance opening 211. The guide space can guide the cargo box to enter the storage compartment 310. Specifically, the guide space can be a V-shaped guide space.

The lifting and transporting mechanism 200 can be lifted and lowered along the height direction of the vehicle-mounted shelf 300. In a preferred solution, at least one column 320 is a guide rail. The lifting and transporting mechanism 200 can cooperate with the guide rail and lift and lower along the guide rail. In this case, the column 320 can not only form the vehicle-mounted shelf 300, but also serve as the lifting and lowering guide rail of the lifting and transporting mechanism 200, which can undoubtedly improve the integration of the transport trolley and make the transport trolley occupy less space.

During the operation of the goods, the lifting and transporting mechanism 200 places the cargo box A in the storage compartments 310 at different heights by lifting. In order to facilitate intelligent management, in the preferred solution, each storage compartment 310 is provided with a cargo detection sensor 350. The cargo detection sensor 350 can detect whether there is a cargo box A in the storage compartment 310, and then feedback to the control system of the transport vehicle. The control system controls the transport vehicle to move to the height corresponding to the storage compartment 310 where no cargo box A is stored, thereby preparing for the subsequent transfer of cargo box A.

The vehicle-mounted shelf 300 may be provided with a position sensor 360 , which can detect the height position of the lifting and transporting mechanism 200 , thereby providing a basis for controlling the lifting and transporting mechanism 200 .

During the transportation of goods, the transport cart moves in the warehouse. The transport cart is usually equipped with a scanning dock, which can scan the box code of the cargo box A on the shelf B to confirm whether it is the target cargo box. In order to facilitate the scanning operation, in the preferred solution, at least one side edge of the lifting and transporting mechanism 200 is provided with a scanning dock 240, and the scanning direction of the scanning dock 240 can be toward the side of the transport cart, so that the code can be scanned from the side. In this case, when the transport cart moves in the travel channel formed by the shelf B, the scanning dock 240 can scan the cargo box A on the shelf B located on one side of the transport cart. This setting method facilitates the scanning operation and can improve the scanning efficiency.

In a preferred solution, the scanning dock 240 can be arranged on the lifting and transporting mechanism 200. Specifically, the scanning dock 240 can be arranged on the lifting base 210 of the lifting and transporting mechanism 200, so that the lifting and transporting mechanism 200 can scan the cargo box A at different heights on the shelf B. Of course, the scanning dock 240 can also scan the shelf codes at different heights on the shelf. The above-mentioned box code and shelf code can be a QR code, a bar code, a character string or an RFID. The embodiment of the present invention does not limit the specific types of the box code and the shelf code. Specifically, the scanning dock 240 can be arranged on the end surface of the support platform 221.

As described above, the transport trolley includes a lifting and transporting mechanism 200, which can be lifted and lowered. Usually, the lifting and transporting mechanism 200 is located on one side of the transport trolley, for example, the lifting and transporting mechanism 200 is arranged on one side of the vehicle-mounted shelf 300. In order to improve the stability of the transport trolley when walking and avoid overturning. In a preferred embodiment, a fork leg 400 can be provided at the bottom end of the side of the carrying platform 100, and the fork leg 400 is provided with a running wheel supported on the ground, and the fork leg 400 and the lifting and transporting mechanism 200 are located on the same side of the carrying platform 100. In this case, the fork leg 400 is supported on the ground by the running wheel, so that the supporting part of the transport trolley includes the carrying platform 100 and the fork leg 400. Obviously, the increase in the supporting part of the transport trolley can further improve the stability of the transport trolley.

At the same time, the fork leg 400 is arranged at the bottom end of the side of the carrying platform 100. In this case, the lifting and transporting mechanism 200 can be lowered to a lower position. Correspondingly, the bottom layer of the shelf 600 can be closer to the ground, which can undoubtedly improve the space utilization rate of the warehouse. Of course, when moving without load, the lifting and transporting mechanism 200 can be in a lower position. At the same time, the fork leg 400 can improve the stability of the transport trolley, so that the transport trolley can travel at a higher speed, which is undoubtedly conducive to the transport trolley to work more efficiently. It should be noted that the bottom end of the side of the carrying platform 100 refers to the end of the side of the carrying platform 100 close to the bottom surface.

In a specific embodiment, the number of fork legs 400 can be two, and an escape space can be formed between the two fork legs 400. The lifting base 210 is at least partially located in the escape space. In this case, the lifting and transporting mechanism 200 can be located at a lower position. Specifically, the lifting base 210 can include a support portion 212 and a bracket 213. The bracket 213 is fixedly connected to the support portion 212. The support portion 212 is sunk into the escape space. The transport body 220 is disposed on the support portion 212. The above-mentioned matching method can undoubtedly further reduce the height of the lifting base 210.

In a preferred solution, an avoidance groove 410 may be provided at the connection between the fork leg 400 and the carrying platform 100, and the bracket 213 may extend into the avoidance groove 410, so that the lifting and transporting mechanism 200 can be placed in a lower position.

In order to facilitate the transfer of cargo boxes, in a preferred solution, a conveying mechanism 225 may be provided on the support surface of the support platform 221, and the conveying mechanism 225 can play a conveying role, thereby allowing the cargo boxes temporarily stored on the support platform 221 to be more quickly delivered to the shelf or storage compartment 310. There are many types of conveying mechanisms 225. In a specific implementation, the conveying mechanism 225 may be a belt conveying mechanism, a roller conveying mechanism, a chain conveying mechanism, etc. This embodiment does not limit the specific type of the conveying mechanism 225.

In this embodiment, the carrying platform 100 includes a driving wheel 110 and other walking mechanisms, which can be driven by a first driving motor to realize the movement of the entire transport vehicle. The carrying platform 100 can be provided with a collision sensor 120, an obstacle avoidance sensor 140, an obstacle avoidance sensor 150, and an obstacle avoidance sensor 160. The above devices are arranged on the carrying platform 100 or the fork leg 400 to prevent the transport vehicle from colliding during the walking process. The transport vehicle is usually driven by a battery, which is usually arranged in the carrying platform 100. The carrying platform 100 can be provided with a charging port 130 to charge the battery.

The transport vehicle disclosed in the embodiment of the present invention has automatic driving, autonomous navigation functions, automatic armband functions, etc.

Please refer to Figures 17 and 18. The transport cart disclosed in the embodiment of the present invention may also include a sorting mechanism 500, and the sorting mechanism 500 includes a base 510 and a sorting manipulator 520. The base 510 can be a separate supporting base, providing an installation base for the sorting manipulator 520. In order to improve the stability of the entire vehicle, in a preferred solution, the base 510 is fixedly connected to the carrying platform 100′, thereby forming the entire foundation of the entire transport cart. The sorting manipulator 520 is arranged on the base 510, so that the cargo box A can be sorted. In a specific implementation, the vehicle-mounted shelf 300′ is installed on the carrying platform 100′, and the lifting and transporting mechanism 200′ is arranged between the vehicle-mounted shelf 300′ and the sorting manipulator 520.

In the specific working process, the lifting and transporting mechanism 200′ can transport the cargo box A to the base 510, and the sorting robot 520 can achieve the purpose of sorting by grabbing the goods in the cargo box A. In a preferred solution, two guide blocks 511 can be provided on the base 510, and the two guide blocks 511 can guide the cargo box A on the base 510. In a more preferred solution, a limit block 512 can be provided on the base 510, and the limit block 512 can limit the position of the cargo box A, and finally make the cargo box A enter the area formed by the two guide blocks 511 and the limit block 512.

In the present application, the sorting robot 520 is generally an automated mechanical structure, which can perform screening grabbing of the goods in the cargo box A according to a preset program, and finally achieve sorting.

The above-mentioned transport cart is usually equipped with a visual system 530.
