The above scheme is implemented to realize the automatic assembly of the material shaft and the automatic unloading of the non-woven fabric roll, thereby improving the degree of automation of non-woven fabric production and reducing labor intensity and production costs. In addition, it can also include an AGV transport device to place the carried material shaft on the supporting shaft device, and transport the non-woven fabric roll on the supporting roll device to a preset location. There are two implementation methods for the A2 state. The first method uses the original winding machine, pushes the rolled non-woven fabric roll to the unloading station through the pushing mechanism on the winding machine, and then transfers the non-woven fabric roll at the unloading station to the shaft support device through the clamping device. The second method is to set a roll support device with a structure consistent with the shaft support device on the side, and hoist the rolled non-woven fabric roll on the winding machine to the roll support device through the clamping device. After the new material shaft is arranged on the winding machine, the rolled non-woven fabric roll on the roll support device is hoisted to the roll support device through the clamping device.

[0027] A further solution is, Figure 5As shown, the clamping mechanism 20 includes a first clamping member 21 and a second clamping member 22 arranged vertically and formed of folding rods. The first clamping member 21 and the second clamping member 22 are arranged in an X shape.

The clamping adjustment mechanism adjusts the first clamping claw 23 and the second clamping claw 24 to be close to each other so as to lift the end of the material shaft from the lower side of the end of the material shaft. The material shaft is clamped in this way, which can effectively avoid the risk of the non-woven fabric roll or the material shaft falling off from the clamping mechanism 20 and improve safety. The clamping adjustment mechanism includes a first adjustment unit 25 and a second adjustment unit 26 which are arranged relative to each other 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 manner.

The connecting rod adjustment mechanism includes four connecting rod parts, and the four connecting rod parts are respectively connected by an upper hinge shaft, a lower hinge shaft, a left hinge shaft, and a right hinge shaft.

The two connecting rod parts located at the lower part of the first adjustment unit 25 are respectively composed of the upper rod bodies of the first clamping member 21 and the second clamping member 22. The upper hinge shaft is fixedly installed on the lifting mounting frame 16. The clamping adjustment mechanism also includes a clamping adjustment component, which is used to adjust the spacing between the upper hinge shaft and the lower hinge shaft. In specific operation, it can be implemented in the following two ways.

The provision of the clamping adjustment plate 28 can effectively prevent the clamping mechanism 20 from colliding with the material shaft and the non-woven fabric roll, and guide the material shaft to ensure the reliability and safety of the clamping. The shaft support device includes two brackets 30 arranged relative to each other along the length direction of the material shaft, the upper end of the bracket 30 is provided with a support member 31, the upper part of the support member 31 is provided with a bayonet for supporting the end of the material shaft, and the outer side of the support member 31 is provided with a guide structure for guiding the material shaft.

The bracket 30 is provided with a flip adjustment cylinder 3327 for adjusting the guiding member 32 to flip. A guiding slope for abutting against the end of the material shaft for guidance can also be provided on the side of the guiding member 32 close to the support member 31, and the spacing between the guiding slope and the support member 31 gradually decreases from top to bottom.

The unloading station is arranged between the winding station and the upper shaft station, and the height of the shaft support device is greater than the height of the winding device and the winding device, which is convenient for the AGV handling device to carry. The winding device and the winding shaft device can be implemented according to the technical solution of the traditional winding machine. Of course, the winding device can also be arranged to be consistent with the shaft support device.

[0030] The regulating cylinder 27 can also be replaced by an regulating electric cylinder or a regulating hydraulic cylinder. A magnetic switch is provided at the regulating cylinder 27, and proximity switches are provided on the first clamping jaw 23 and the second clamping jaw 24 respectively; the regulating cylinder 27 is connected to the air source device through an air supply line, and an air cut-off pressure maintaining device is provided on the air supply line.

The lifting guide column 17 is provided with a vertically arranged lifting adjustment rack, and the lifting adjustment rack and the lifting adjustment gear are meshed and driven. In this way, the two lifting guide columns 17 can be synchronously adjusted by the lifting adjustment motor 14 to drive the lifting mounting frame 16 to lift and lower smoothly. The lifting adjustment mechanism also includes a wire length measuring device. By setting up a wire length measuring device and combining it with the servo encoding of the lifting and adjusting motor 14, it is possible to double-judge the rising or falling position of the clamping device, thereby further enhancing the accuracy of the material shaft clamping and positioning, so as to improve the safety of the lifting operation. Two walking guide rails are arranged on the frame 10, and a walking slider for slidingly cooperating with the walking guide rails is arranged on the walking trolley 11.

[0032] The detection device may specifically include travel detection sensors for detecting the movement of the traveling trolley 11, which are respectively arranged at the corresponding winding station, unloading station, and upper shaft station, and various lifting detection sensors for detecting the height of the clamping device. The travel detection sensor and the lifting detection sensor may specifically be constituted by a limit switch. The control device analyzes and processes the signals detected by each sensor, so that the clamping device can accurately clamp and arrange the material shaft or non-woven fabric roll. 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. The technical solution provided by the present invention does not require the modification of the traditional winding machine, so the implementation cost is low.
