Description

Technical Field

[0001] This utility model relates to the field of RGV trolley technology, and in particular to a double-layer roller rotatable RGV trolley. Background Technology

[0002] RGV is an abbreviation for Rail Guided Vehicle, a type of driverless vehicle that operates automatically on fixed tracks. Its main function is to automatically transport materials (such as pallets, bins, and containers) between different stations in warehouses, production lines, or logistics centers. It typically features automatic navigation (along the track), automatic positioning (stopping at designated stations), and automatic loading and unloading capabilities.

[0003] The existing RGV trolley can only travel in a straight line on the same track. If it needs to turn, it needs to use another vertical track, so it is not suitable for single-track situations. Summary of the Invention

[0004] According to an embodiment of the present invention, a double-layer roller rotatable RGV trolley is provided, comprising:

[0005] The frame has multiple wheels underneath (this is existing technology).

[0006] The first drive module (belonging to the prior art) has its output end connected to two of the walking wheels, which is used to drive the trolley to move on the track;

[0007] The first conveying module is located at the bottom of the frame.

[0008] The second conveying module is located at the top of the frame.

[0009] The rotary drive module is connected to the second conveying module and can drive the second conveying module to rotate.

[0010] Furthermore, the first drive module includes: a first drive mechanism and a pair of universal couplings; the output end of the first drive mechanism is connected to one end of the pair of universal couplings respectively, and can drive the universal couplings to rotate; the other end of the pair of universal couplings is connected to a traveling wheel respectively.

[0011] Furthermore, the first conveying module includes: a first conveying frame, an electric roller, and a plurality of first driven rollers;

[0012] The first conveyor frame is fixedly connected to the frame body;

[0013] The electric roller is rotatably connected to the first conveyor frame at both ends and electrically connected to an external power source via wires;

[0014] Several first driven rollers are rotatably connected to the first conveyor frame in sequence;

[0015] The electric drum has a pair of first gears at one end, and a pair of second gears at one end of the first driven drum. The first gears and second gears are connected by a chain, and the electric drum drives the first driven drum to rotate through the chain.

[0016] Furthermore, a first transition roller is installed at each of the front and rear ends of the first conveyor frame.

[0017] Furthermore, the second conveying module includes: a second conveying frame, a second drive mechanism, a driving roller, and several second driven rollers;

[0018] The second conveyor is connected to the output end of the rotary drive module, which can drive the second conveyor to rotate.

[0019] One end of the driving roller is provided with a pair of third gears, and the second driven roller is provided with a pair of fourth gears, with one of the third gears and the fourth gear connected by a chain;

[0020] The output end of the second drive mechanism is connected to another third gear via a chain, which is used to drive the drive roller to rotate. The drive roller drives several second driven rollers to rotate via a chain.

[0021] Furthermore, a second transition roller is installed at each of the front and rear ends of the second conveyor frame.

[0022] Furthermore, the rotary drive module includes: a rotary drive mechanism, a driving gear, and a driven gear;

[0023] The rotary drive mechanism is fixedly connected to the frame, and its output end is connected to the drive gear, which can drive the drive gear to rotate.

[0024] The driven gear meshes with the driving gear. The top of the driven gear is fixedly connected to the second conveying module, and the bottom is rotatably connected to the frame via a rotating shaft.

[0025] According to an embodiment of this utility model, the double-layer roller-rotatable RGV trolley has a two-layer structure, each layer equipped with a roller conveyor. It can transport two units (such as two hoppers or two pallets) in a single run, reducing empty runs. Alternatively, one layer can receive upstream materials while the other conveys downstream materials, implementing simple buffering or sorting logic during movement. The upper and lower layers are designed to handle materials of different sizes and loads. The entire upper roller conveyor can rotate 90°, 180°, or any angle, with multiple station interfaces located on the side of the RGV trolley along the vertical track. When the RGV reaches a station, the upper roller rotates 90° to align with the interface of the lateral station for receiving or feeding materials. This allows a single RGV to serve stations from different directions (front, back, left, right) simply by rotating the roller platform to align with the corresponding interface, improving the versatility and flexibility of the equipment. In areas with limited space, the rotation function reduces the turning radius and adjustment space required for the RGV.

[0026] It should be understood that both the foregoing general description and the following detailed description are exemplary and intended to provide further illustration of the claimed technology. Attached Figure Description

[0045] Furthermore, such as Figure 3 , 8 As shown, in this embodiment, the first conveying module 3 includes: a first conveying frame 31, an electric roller 32, and a plurality of first driven rollers 33;

[0046] The first conveyor frame 31 is fixedly connected to the frame 1;

[0047] The electric roller 32 is rotatably connected to the first conveyor frame 31 at both ends and electrically connected to an external power source via wires; the electric roller 32 can reduce the space occupied in the lower layer.

[0048] A number of first driven rollers 33 are rotatably connected to the first conveyor frame 31 in sequence;

[0049] The electric roller 32 has a pair of first gears at one end, and the first driven roller 33 has a pair of second gears at one end. The first gears and the second gears are connected by a chain, and the electric roller 32 drives the first driven roller 33 to rotate through the chain.

[0050] Furthermore, such as Figure 1 , 3 As shown, in this embodiment, a first transition roller 34 is provided at each of the front and rear ends of the first conveyor frame 31 for connecting and transitioning with the external conveying device.

[0051] Furthermore, such as Figure 2 As shown, in this embodiment, the second conveying module 4 includes: a second conveying frame 41, a second driving mechanism 42, a driving roller 43, and a plurality of second driven rollers 44;

[0052] The second conveyor frame 41 is connected to the output end of the rotary drive module 5, and the rotary drive module 5 can drive the second conveyor frame 41 to rotate.

[0053] One end of the driving roller 43 is provided with a pair of third gears, and the second driven roller 44 is provided with a pair of fourth gears, with one of the third gears and the fourth gear connected by a chain.

[0055] Preferably, the second drive mechanism 42 adopts a servo motor, which is the prior art.

[0056] Furthermore, such as Figure 1 As shown, in this embodiment, a second transition roller 45 is provided at each of the front and rear ends of the second conveyor frame 41 for connecting and transitioning with the external conveying device.

The drive roller 43 then drives the remaining second driven rollers 44 to rotate, conveying the materials. When the second conveying module 4 needs to rotate at a certain angle, the rotary drive mechanism 51 drives the drive gear 52 to rotate, which in turn drives the driven gear 53 to rotate, thus rotating the second conveying module 4 to the specified angle.

[0063] Above, refer to Figures 1-8 This invention describes a double-layer roller rotatable RGV trolley according to an embodiment of the present invention. The double-layer roller design allows the RGV to transport materials from two units in a single run, reducing empty runs and improving transportation efficiency.
