Description

Technical Field

[0001] The utility model relates to the technical field of automated transportation, in particular to a transportation sorting vehicle and a rail transportation train. Background Art

[0002] With the development of automated logistics systems and automated warehouses, RGV (automatic guided vehicle) trolleys have emerged. RGV trolleys can be used in warehouses with various high-density storage methods. The trolley channel can be designed to be arbitrarily long, which can increase the storage capacity of the entire warehouse. There is no need for forklifts to enter the aisles during operation, making it safer. By taking advantage of the fact that forklifts do not need to enter the aisles, combined with the rapid operation of the trolley in the aisles, the operating efficiency of the warehouse can be effectively improved.

[0003] In the prior art, conventional RGV systems are usually composed of a power system, a guidance system, a control system, and a transportation system. These systems are usually integrated into a single vehicle, so that each RGV independently completes all functions of power drive, guidance control, and cargo transportation. The problems caused by this include at least:

[0004] 1) Since each RGV is equipped with an independent drive system, each vehicle needs to carry a corresponding battery or power device, which not only increases the weight of the vehicle, but also causes uneven power distribution of a single RGV, reducing the efficiency of the system;

[0005] 2) Since each RGV requires a complete control system and guidance system, the structure of each vehicle is complex, and the manufacturing and maintenance costs are high;

[0006] 3) In some application scenarios, it is not necessary for each vehicle to have independent power and control capabilities. For example, in scenarios where only simple transportation tasks are required, independent power and control systems will result in waste of resources and increased costs. Utility Model Content

[0007] The utility model discloses a transport sorting vehicle and a rail transport train, aiming to solve the technical problems existing in the prior art.

[0008] The utility model adopts the following technical solutions:

[0016] As a preferred technical solution, the material throwing assembly also includes a zero position sensor, which is connected to the roller drive module to determine the working state of the material throwing roller module.

[0017] As a preferred technical solution, a zero position sensor is arranged on one side of the conveyor belt to detect the zero position of the conveyor belt.

[0024] The power locomotive is connected to the transport sorting vehicle to provide forward power;

[0025] The transport sorting vehicle is used to obtain forward momentum and sort the items according to the control signal;

[0041] In order to solve the problems existing in the prior art, the present embodiment provides a transport sorting vehicle 20, which is applied to a rail transport train, such as Figure 1 The rail transport train further has a power front 10 for providing forward driving force and a power rear 30 for providing sorting power for the transport sorting vehicle 20; preferably, the rail transport vehicle is arranged on a double-row transport track 40, and the transport track 40 can be configured as an open-loop track or a closed-loop track according to the site; the rail transport train can be applied to logistics sorting systems, manufacturing production lines, airport baggage handling systems, agricultural product sorting and transportation systems, agricultural production materials distribution systems, warehouse management systems, pharmaceutical logistics systems, port container sorting and transportation systems and other scenarios, and examples are not listed one by one here.

[0042] like Figure 2 — Figure 5 In a preferred embodiment, the transport sorting vehicle 20 includes a chassis assembly 21 and a throwing assembly 22. The chassis assembly 21 is used to support and move the entire transport sorting vehicle 20, and its structure includes a chassis frame 211, a connecting rod 215, a guide roller 213 and a walking roller 214; the throwing assembly 22 is used to transport the corresponding goods and throw them sideways, and its structure includes a throwing roller module, a roller driving module 224 and a zero position sensor 223.

[0043] like Figure 2 , Figure 3 In a preferred embodiment, the chassis frame 211 is configured as a sturdy frame structure for supporting the entire transport sorting vehicle 20 and the goods it carries; in a preferred embodiment, the chassis frame 211 is made of high-strength steel or aluminum alloy material to provide sufficient carrying capacity to ensure that the transport sorting vehicle 20 can operate stably for a long time in various warehousing and logistics scenarios.

[0044] Preferably, the walking rollers 214 are arranged at the bottom of the chassis frame 211 to support the weight of the entire transport sorting vehicle 20 and reduce the friction with the transport track 40 by rolling, thereby achieving smooth movement; the guide rollers 213 are arranged on the outside of the chassis frame 211 to be clamped on the outside of the double-track transport track 40 to keep the transport sorting vehicle 20 running along the direction of the transport track 40.

[0045] In a preferred embodiment, travel rollers 214 are arranged on both sides of the left and right sides of the chassis frame 211. The axes of the travel rollers 214 are horizontally arranged and perpendicular to the axes of the transport rails 40, so that the travel rollers 214 can abut against the top of the transport rails 40; more preferably, the travel rollers 214 are evenly distributed at the four corners or multiple key support points of the bottom surface of the chassis frame 211 to disperse the weight load of the transport sorting vehicle 20 and ensure its smooth operation on the transport rails 40; the number and size of the travel rollers 214 are configured according to the size / load of the chassis frame 211, and preferably at least four rollers are configured. If the transport sorting vehicle 20 is longer or heavier, the number of rollers can be increased to further disperse the load.

[0046] In a preferred embodiment, the guide rollers 213 are installed on both sides of the bottom of the chassis frame 211, and the guide rollers 213 on both sides are respectively abutted against the two sides of the transport track 40. By contacting the transport track 40, the lateral movement of the transport sorting vehicle 20 is limited, thereby keeping the transport sorting vehicle 20 able to run along the track direction and preventing it from deviating from the transport track 40.

[0047] Preferably, the number and position of the guide rollers 213 are configured according to the design of the transport track 40 or the length of the transport sorting vehicle 20. Preferably, two guide rollers 213 are installed at the front and rear or the middle and rear of the chassis frame 211 to effectively limit the lateral movement of the mobile transport sorting vehicle 20. If the transport track 40 is long or the operating environment is complex, the number of guide rollers 213 can be increased to further improve the guiding effect.

[0048] like Figure 2 , Figure 5 Preferably, a connecting rod 215 is arranged at the front end of the chassis frame 211 to obtain forward power and transmit the power to the transport sorting vehicle 20; in the entire rail transport train, when only one transport sorting vehicle 20 is arranged, the connecting rod 215 of the transport sorting vehicle 20 is directly connected to the front power locomotive 10 to obtain the forward power provided by the power locomotive 10; when several transport sorting vehicles 20 are arranged in the entire rail transport train, adjacent transport sorting vehicles 20 are connected by connecting rods 215, and the frontmost transport sorting vehicle 20 is connected to the power locomotive 10.

[0049] In a preferred embodiment, a connecting plate 212 is fixedly provided at the front end of the chassis frame 211, and the rear end of the connecting rod 215 is connected to the connecting plate 212 via a fisheye bearing 216. The connecting plate 212 and the fisheye bearing 216 are fixed by connecting bolts, and the connecting rod 215 and the fisheye bearing 216 are locked by a lock nut. The front end of the connecting rod 215 is used to connect to another transport sorting vehicle 20 or a power locomotive 10 in front.

[0050] Specifically, the fisheye bearing 216 provides a flexible connection point, which allows the connecting rod 215 to move freely within a certain range, ensuring smoother power transmission and reducing mechanical stress and wear caused by power transmission, so as to improve the durability and service life of the connecting rod 215.

[0051] Preferably, the throwing roller module is used to throw the objects sideways, and the roller driving module 224 is connected to the throwing roller module to receive driving instructions and drive the throwing roller module to rotate.

[0052] like Figure 4In a preferred embodiment, the throwing roller module is provided with two rollers 221 and a conveyor belt 222. The conveyor belt 222 is arranged on the outside of the two rollers 221, and the conveyor belt 222 is driven by the rollers 221 to move; the two rollers 221 are arranged on the top of the chassis frame 211, and are both arranged parallel to the axis of the transport track 40, so that the movement direction of the conveyor belt 222 is perpendicular to the running direction of the transport sorting vehicle 20, that is, lateral movement, to ensure that the conveyor belt 222 can throw materials sideways, and the distance between the two rollers 221 is preferably the same width as the chassis frame 211, to ensure that the conveyor belt 222 can effectively cover the entire width of the chassis frame 211, to ensure that the goods can roll sideways to complete the sorting task.

[0053] In a preferred embodiment, the throwing component 22 also includes a zero position sensor 223, which is arranged on one side of the conveyor belt 222 and is used to detect the zero position of the conveyor belt 222. The zero position sensor 223 is connected to the roller drive module 224 and transmits the feedback signal obtained by the detection to the roller drive module 224. The roller drive module 224 receives the driving instruction from the control system and adjusts and controls the rotation speed and direction of the roller 221 based on the feedback signal from the zero position sensor 223, so as to ensure the accurate positioning of the conveyor belt 222 and the accurate throwing of objects.

[0054] Optionally, the zero position sensor 223 may be configured as a photoelectric sensor, a proximity sensor or a Hall sensor, which is not specifically limited herein.

[0055] In another embodiment of the utility model, a rail transport train for automatic sorting is provided, including a power locomotive 10, the above-mentioned transport and sorting vehicle 20 and a power locomotive tail 30; wherein the power locomotive is connected to the transport and sorting vehicle 20 to provide forward power, the transport and sorting vehicle 20 is used to obtain forward power and to perform material throwing and sorting according to control signals; the power locomotive tail 30 is used to provide the transport and sorting vehicle 20 with the power required for throwing materials.

[0056] Preferably, the number of the transport sorting vehicles 20 can be increased or decreased according to transportation requirements, and adjacent transport sorting vehicles 20 are connected via a connecting rod 215 .

[0057] Compared with the prior art, in the rail transport train in the above embodiment, only the front-end power locomotive 10 is used to provide forward driving force and send the control instruction of throwing materials to the transport sorting vehicle 20 at the rear. The transport sorting vehicle 20 is connected to the power locomotive 10 through the connecting rod 215 and obtains the forward driving force. It itself does not have forward driving force and is only used for transporting goods and throwing materials sideways. A power locomotive tail 30 is also connected to the rear of the train to provide the transport sorting vehicle 20 with the power required for throwing materials.

[0058] This solution reduces the demand for drive equipment for each transport sorting vehicle 20, reduces the power system configuration cost, is conducive to reducing the use cost and maintenance difficulty, and makes the power distribution more uniform, avoiding the problem of uneven power distribution of a single RGV, thereby improving the overall efficiency of the system, avoiding redundancy in power distribution, and being able to adapt to the needs of modern logistics and automatic sorting systems.

[0059] The embodiments of the utility model are described above in conjunction with the accompanying drawings, but the utility model is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the enlightenment of the utility model, ordinary technicians in this field can also make many forms without departing from the scope of protection of the utility model and the claims, all of which are within the protection of the utility model.
