[0002] In the traditional non-woven fabric production process, a rotating material shaft on a winding machine is used to wind the continuously produced non-woven fabric. After winding, the non-woven fabric roll is unloaded by manually operating a lifting hook, and then a new material shaft is manually loaded onto the winding machine to wind the non-woven fabric again. This process is repeated to achieve reliable material collection operation for the non-woven fabric. However, when implementing this method, on the one hand, manual assistance is required for operation, resulting in high labor intensity and cost. On the other hand, it is necessary to manually operate the lifting hook to hook both ends of the material shaft and operate the traveling crane to move the non-woven fabric roll. During the movement of the non-woven fabric roll, situations such as tilting and unhooking may occur, resulting in poor safety. Therefore, it is necessary to solve this problem to achieve the automation of non-woven fabric material shaft transfer, reduce production costs, and improve safety. Summary of the Invention

Detailed Description of the Invention

[0024] In order to make the purpose and advantages of the present utility model more clear and understandable, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection specifically claimed for the present utility model.

[0025] As used herein, terms such as "parallel", "perpendicular", etc. are not limited to their strict geometric definitions, but include tolerances for machining or human errors that are reasonable and inconsistent.

[0026] As Figures 1 to 4 As shown, the present utility model provides a material shaft transfer system for non-woven fabric production, including a frame 10. A movable traveling trolley 11 is arranged on the frame 10. The traveling trolley 11 is connected to a traveling drive mechanism for driving it to move. A winding station, a discharging station, and a shaft loading station are arranged on the lower side of the moving path of the traveling trolley 11. A winding device for driving the material shaft to rotate to wind the produced non-woven fabric is arranged at the winding station. A roll supporting device for supporting the non-woven fabric roll is arranged at the discharging station. A shaft supporting device for supporting the material shaft is arranged at the shaft loading station. Two oppositely arranged clamping devices are arranged on the traveling trolley 11 in a lifting manner. The two clamping devices are connected to a lifting adjustment mechanism for adjusting their lifting. The clamping device includes a clamping mechanism for clamping the end of the material shaft and a clamping adjustment mechanism. The clamping adjustment mechanism adjusts the clamping mechanism to clamp and release the end of the material shaft. It also includes a control device and a detection device. The detection device detects the state of the material shaft and each device. The control device analyzes and processes the signals detected by the detection device and adjusts each device to switch between state A1 and state A2 according to the analysis and processing results. State A1 is: the clamping device is used to transfer the material shaft on the shaft supporting device to the winding device for assembly; State A2 is: the clamping device is used to transfer the wound non-woven fabric roll on the discharging station / winding device to the shaft supporting device. By implementing the above solution, automatic assembly of the material shaft and automatic unloading of the non-woven fabric roll can be achieved, thereby improving the automation degree of non-woven fabric production, reducing labor intensity and production costs. In addition, an AGV handling device may also be included to place the carried material shaft on the shaft supporting device and transport the non-woven fabric roll on the roll supporting device to a preset location. There are two implementation manners for state A2. The first is to use the original winding machine. The wound non-woven fabric roll is pushed to the discharging station through the pushing mechanism on the winding machine, and then the non-woven fabric roll at the discharging station is transferred to the shaft supporting device by the clamping device. The second is to arrange a roll supporting device with a structure consistent with that of the shaft supporting device on the side. The wound non-woven fabric roll on the winding machine is hoisted to the roll supporting device by the clamping device. After a new material shaft is arranged on the winding machine, the wound non-woven fabric roll on the roll supporting device is hoisted to the roll supporting device by the clamping device.

[0027] A further solution is as follows Figure 5 As shown, the clamping mechanism 20 includes a first clamping member 21 and a second clamping member 22 which are vertically arranged and composed of folding rods.

The clamping adjustment mechanism adjusts the first clamping jaw 23 and the second clamping jaw 24 to approach each other and lift and support the end of the material shaft from the lower side of the end of the material shaft. By clamping the material shaft in this way, the risk of the non-woven fabric roll or the material shaft falling off the clamping mechanism 20 can be effectively avoided, and the safety is improved. The clamping adjustment mechanism includes a first adjustment unit 25 and a second adjustment unit 26 which are arranged oppositely at intervals along the length direction of the material shaft. The first adjustment unit 25 and the second adjustment unit 26 are installed in a suspended state.

And when the wire drawing length measuring device and the servo encoding fail, the rising or falling position of the clamping device can be controlled to ensure the safety of the lifting operation.
