[0018] like Figure 1-3 As shown, the single-powered dual-action trolley of this invention includes a battery, a drive unit, a lifting unit, a wireless communication module, and a self-guiding system. The various functional units are described in detail below.

[0019] Storage battery:

[0020] As the energy supply device for the vehicle, the battery 12 can be, for example, a lithium iron phosphate battery, providing power to the drive unit, the lifting unit, and other possible electronic components (such as a wireless communication module). The battery 12 preferably has a rechargeable feature, with a charging slider located at the rear of the vehicle. Through contact-based automatic charging, it can be charged by an external power source when the vehicle is not in operation, ensuring sufficient energy support for the vehicle during extended periods of operation.

[0021] Drive unit:

[0022] Drive unit 5 is the core of the vehicle's power system, responsible for providing the vehicle with the power to move along the track. It can precisely control the vehicle's speed and direction, ensuring that the vehicle travels smoothly along the preset path.

[0023] Its design employs a high-efficiency servo motor system, equipped with a corresponding transmission device, and includes a drive wheel 2 and a driven wheel 3 to achieve effective power transmission and speed regulation.

[0024] Lifting unit:

[0025] The lifting unit has the key functions of self-lifting and lifting the cotton sliver can. When the lifting fulcrum is upward, it lifts the cover 1 and the cotton sliver can; when the lifting fulcrum is downward, it lifts the trolley itself to a specific position on the mother car. During operation, when the trolley reaches the position of the mother car, the lifting unit can automatically start and raise itself to a suitable height for better docking with the mother car and completing the operation of moving together with the mother car.

[0026] At the same time, it also has enough force to lift the sliver can from the track position, ensuring that the sliver can remains stable during transportation on the track and conveyor line, and preventing the sliver can from shaking or tipping over.

[0027] The lifting unit includes:

[0028] 1. Power System

[0029] The system is driven by a servo motor 14, and the torque is amplified and the speed is adjusted by a precision reducer 13, such as a star gear reducer. The output shaft of the reducer 13 is directly connected to the first set of drive shafts. The servo motor 14 is equipped with an absolute encoder, which can achieve a rotation angle control accuracy of ±0.1°.

[0030] 2. Cam assembly structure

[0031] Two sets of symmetrically arranged lifting cam systems, each set containing two coaxial lifting cams 4, with all four lifting cams 4 moving simultaneously, up and down. The lifting cams 4 can be circular or elliptical, preferably elliptical. The lifting cams 4 are rotatably connected to the two side walls of the vehicle.

[0032] Drive shaft assembly: A lifting cam is installed at each end of the shaft, and a deep groove ball bearing is installed at the end of the lifting cam. The function of the bearing is to reduce friction and change sliding friction to rolling friction.

[0033] Driven shaft assembly: Similar to the drive shaft configuration, it is fixed to the base plate by two mounting brackets 11 to ensure that it is on the same horizontal plane as the drive shaft.

[0034] 3. Synchronous transmission mechanism

[0035] An orthogonal bevel gear pair is adopted, and bevel gears 10 are installed at both ends of the solid connecting rod 9.

[0036] When the cotton swab can needs to be lifted, the servo motor 14 drives it. After the torque is amplified and the speed is adjusted by the reducer 13, the output shaft of the reducer 13 drives the drive shaft to rotate. The drive shaft drives the driven shaft to rotate synchronously through the synchronous transmission mechanism (solid connecting rod 9 + bevel gear 10). The four lifting cams 4 rotate with the rotation of the drive shaft and the driven shaft. When the raised part of the lifting cam 4 rotates upward, the car cover can be lifted.

[0037] Wireless communication module:

[0038] The wireless communication module enables the vehicle to interact with external control systems or other devices and can be installed anywhere inside the vehicle. Through wireless signals, the vehicle can receive operating commands from the control center, such as start, stop, speed adjustment, and lifting operations. Simultaneously, it can also feed back its own operational status information (such as location, battery level, and fault information) to the control center.

[0039] This wireless communication function enables remote control and intelligent management of the vehicle, improving the automation and flexibility of the production process.

[0040] Self-guided system:

[0041] The self-guiding system ensures the trolley moves accurately on the track. It utilizes various sensor technologies, such as ultrasonic sensors and magnetic sensors, to detect the relative position and directional deviation between the trolley and the track. An ultrasonic sensor can be installed at the front of the trolley to determine its position relative to the canister, allowing the trolley to automatically adjust its running position.

[0042] When a deviation is detected, the self-guiding system will automatically adjust the direction of the trolley to keep it on the predetermined track, thereby improving the accuracy and reliability of transportation and preventing the trolley from derailing or deviating from the predetermined path.

[0043] An ultrasonic sensor is installed at the front of the vehicle. When the vehicle is traveling on the track, the sensor can detect the position of the cotton swab tube to ensure that the vehicle is in an accurate position.

[0044] Alternatively, a cleaning brush 15 can be installed at the front of the trolley. As the trolley travels along the track, it pushes the track lint to the end of the track, where a negative pressure suction port can remove the lint. The cleaning brush 15 can be an aluminum alloy strip industrial dustproof brush, fixed to the front of the trolley with screws.

[0045] Working principle and process

[0046] First, the trolley starts powered by the battery 12, and the drive unit 5 drives the trolley to run along the track to the cotton swab placement area.

[0047] Once the trolley reaches the designated position, the lifting unit activates, and the lifting cam raises the trolley's cover to a suitable height so that it can be lifted off the track from the cotton swab can.

[0048] Next, the lifting unit remains in place, and the trolley lifts and transports the sliver canister, ensuring that the sliver canister is securely mounted on the trolley.

[0049] During transportation, the self-guiding system continuously adjusts the trajectory of the trolley and ensures the precise movement of the trolley on the track by adjusting the direction of the drive unit 5.

[0050] When the trolley reaches its destination, the lifting unit works again to lower the cotton sliver canister to the designated position, ready for the next transport task.

[0051] Throughout the process, the wireless communication module maintains a constant connection with the control center, receiving and sending relevant instructions and status information to enable remote monitoring and management of the vehicle.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this utility model. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the protection scope of the claims of this utility model.
