[0023] The utility model will be further described in detail in combination with examples, but the implementation mode of the utility model is not limited to this.

[0024] Example 1

[0025] As Figure 1As shown, this embodiment provides a walking mechanism suitable for automatic doffing of viscose filament spinning machines, including a three-dimensional frame, an automatic doffing device bracket 1, and a controller. The three-dimensional frame includes two columns 2 and a crossbeam 3 connected to the top of the two columns 2 at both ends. The automatic doffing device bracket 1 and the crossbeam 3 are connected by a sliding connection assembly, and the sliding connection assembly is driven by a drive assembly 11. A position sensor and a vision sensor are provided on the crossbeam 3. The position sensor, the vision sensor, and the drive assembly 11 are electrically connected to the controller.

[0026] In this embodiment, the position sensor is a Hall sensor and the vision sensor is a laser scanner.

[0027] In this embodiment, the controller monitors the winding status of the filament spindle on the winding device of the viscose filament spinning machine in real time through a vision sensor. When the winding device needs to drop the filament onto the bobbin, the controller drives the sliding connection component through the drive component 11 to move the automatic bobbin dropping device bracket 1 to the position where the bobbin needs to be dropped. The position sensor monitors the position of the automatic bobbin dropping device bracket 1 in real time. When the automatic bobbin dropping device bracket 1 moves to the position where the bobbin needs to be dropped, the controller controls the automatic bobbin dropping device on the automatic bobbin dropping device bracket 1 to start dropping the bobbin, providing a walking mechanism with a predetermined trajectory for the automatic bobbin dropping robot.

[0028] Example 2

[0029] like Figure 2 As shown, the difference between this embodiment and Embodiment 1 is that, in this embodiment, the connecting assembly includes a guide rail I4 disposed on the top of the crossbeam 3 and rollers I5 disposed on the automatic drum dropping device bracket 1. The rollers I5 are slidably engaged with the guide rail I4. The automatic drum dropping device bracket 1 has a connecting frame 6 disposed on its top, which includes a connecting plate 7 and a support arm 8. The bottom of the connecting plate 7 is fixedly connected to the top of the automatic drum dropping device bracket, and the support arm 8 is perpendicularly connected to the top surface of the connecting plate 7. The rollers I5 are rotatably connected to the support arm 8. There are two guide rails I4, which are arranged parallel to each other on both sides of the top surface of the crossbeam 3. Support arms 8 are disposed at the four corners of the top of the connecting plate 7. There are four rollers I5, and each support arm 8 is rotatably connected to a roller I5 that is slidably engaged with the guide rail I4. Guide rails II are also disposed on both sides of the bottom surface of the crossbeam 3, and each support arm 8 is also rotatably connected to a roller II that is slidably engaged with the bottom guide rail II of the crossbeam 3. The drive assembly 11 includes a variable frequency motor and a reducer. The variable frequency motor is fixedly connected to the support arm 8, and the output shaft of the variable frequency motor is driven by the reducer. The output end of the reducer is driven by the roller 5. The rest of the structure is the same as in Embodiment 1.

[0030] In this embodiment, the guide rail I4 is installed on the top of the cross beam 3 to provide a precise guide path for the movement of the automatic doffing device support 1; the roller I5 is in sliding cooperation with the guide rail I4, which reduces the friction resistance and enables the automatic doffing device support 1 to move smoothly on the cross beam 3. Through the close cooperation of the roller 5 and the guide rail 4, the connecting assembly provides additional stability to the entire walking mechanism. Even in the case of high-speed movement or heavy load, the stability of the walking mechanism can be maintained without shaking.

[0031] In this embodiment, the guide rail II is arranged on both sides of the bottom surface of the cross beam 3, and the roller II is arranged in sliding cooperation with the guide rail II at the lower part of the support arm 8. Through the cooperation of the guide rail I and the guide rail II, the cross beam is clamped by the two upper and lower rollers arranged on the four support arms 8, which makes the connection between the automatic doffing device support 1 and the cross beam 3 more stable and less likely to fall off.
