[0027] See also Figure 1-4 A wire rope automatic pay-off device comprises a bracket 1 and a winch 2, the bracket 1 is provided with a pay-off structure 3 for controlling the wire feeding amount, the winch 2 is wound with a metal wire 4, the metal wire 4 is wound on the pay-off structure 3, and the side of the bracket 1 is provided with a processing device 5 for processing the metal wire 4, such as a cutting machine, a chuck machine, etc.; the pay-off structure 3 can be used to control the pay-off length, and the length of each pay-off can be achieved by adjusting the distance between the moving wheel 31 and the fixed wheel 32, which is convenient for adjustment. Compared with traditional CNC, the mechanical method is easier to use and is conducive to reducing production costs.

[0028] The wire-releasing structure 3 includes a moving wheel 31 and a fixed wheel 32 arranged on the bracket 1, and the metal wire 4 is wound on the fixed wheel 32 and the moving wheel 31. The moving wheel 31 and the fixed wheel 32 are provided with more than one wheel groove, and the metal wire 4 is arranged in the wheel groove; since there is more than one wheel groove on the fixed wheel 32 and the moving wheel 31, a relatively long metal wire 4 can be wound over a shorter distance.

[0029] The bracket 1 is divided into a vertical bracket 101 and a horizontal bracket 102. The moving wheel 31 and the fixed wheel 32 are arranged on the vertical bracket 101. The horizontal bracket 102 is provided with a guide wheel 6, and the metal wire 4 is attached to the guide wheel 6. The guide wheel 6 is used to control the direction of the wire output, and try to keep it flush with the processing equipment 5 to reduce the loss of the metal wire 4 caused by friction.

[0030] A sensing plate 7 is provided on the side of the driving wheel 31, and a sensing probe 8 is provided on the vertical bracket 101. The sensing probe 8 is connected to the PLC signal, and the PLC is connected to the winch 2 and the processing equipment 5 signal; the PLC is used to control the opening and closing of the winch 2 and the processing equipment 5. When the sensing plate 7 passes through the sensing probe 8, the sensing probe 8 receives the signal and transmits it to the PLC, so that the PLC is used to control the winch 2 and the processing equipment 5 to realize automated production.

[0031] A slide rail 9 is provided on the vertical bracket 101, a slider 10 is provided on the slide rail 9, the moving wheel 31 is installed on the slider 10, and the induction plate 7 is arranged on the slider 10; the slider 10 can slide along the vertical bracket 101, and the existence of the slide rail 9 and the slider 10 can facilitate the movement of the moving wheel 31.

[0032] The sensing probe 8 is divided into an upper probe 81 and a lower probe 82 . The lower probe 82 is installed at the bottom end of the vertical bracket 101 , and the upper probe 81 is arranged on the side of the vertical bracket 101 . There are two groups of sensing probes 8 .

[0033] The upper probe 81 and the lower probe 82 respectively give the PLC a wire-releasing signal and a wire-reeling signal. When the induction plate 7 moves to the upper probe 81, the upper probe 81 gives the PLC a signal, the winch 2 is turned on, the processing equipment 5 is turned off, and the moving wheel 31 drives the slider 10 to descend under the action of gravity to realize wire-releasing. When the moving wheel 31 drives the slider 10 to descend to the bottom end under the action of gravity, the induction plate 7 moves to the lower probe 82 and gives the PLC signal. The PLC controls the winch 2 to lock, and at the same time the processing equipment 5 is turned on. The processing equipment 5 reels in the wire and pulls the metal wire 4 into the equipment. As the metal wire 4 enters the processing equipment 5, the moving wheel 31 is pulled up. As the moving wheel 31 rises to the top and the induction plate 7 moves to the upper probe 81, the above process is repeated.

[0034] The two groups of induction probes 8, the group closer to each other, play the role of normal control of releasing and retracting the line, and the group farther apart can play the role of emergency stop equipment. In dangerous situations, it can stop quickly and reduce the occurrence of dangerous accidents.

[0035] A mounting plate 11 is provided on the side of the vertical bracket 101, and a mounting groove 17 is provided on the mounting plate 11. The sensing probe 8 is installed in the mounting probe. The mounting groove 17 is in a long strip shape, and the upper probe 81 is fixed in the mounting groove 17 by screws and nuts; in this way, the position of the sensing probe 8 can be adjusted, thereby changing the distance between the upper probe 81 and the lower probe 82, thereby controlling the moving distance of the driving wheel 31, so that the length of the line release can be controlled.

[0036] A buffer rod 12 is provided at the bottom end of the vertical bracket 101 and is located below the moving wheel 31. A connecting plate 13 is provided at the end of the fixed wheel 32 of the vertical bracket 101, and a positioning block 14 with a metal wire 4 inserted therethrough is provided on the connecting plate 13. The buffer rod 12 can be used to avoid damage caused by the moving wheel 31 not stopping in time when it falls. At the same time, the positioning block 14 can fix the angle at which the metal wire 4 enters the fixed wheel 32, thereby reducing wear.

[0037] A support rod 15 is provided on the transverse bracket 102, and the guide wheel 6 is fixed to the support rod 15 by screws. A positioning rod 16 is provided on the support rod 15 and is in contact with the guide wheel 6. The metal wire 4 is located between the positioning rod 16 and the guide wheel 6. The guide wheel 6 can adjust its height through the support rod 15 to adapt to processing equipment 5 with different wire entry heights. The positioning rod 16 can prevent the metal wire 4 from falling off the guide wheel 6.

[0038] A wire-paying method, using a wire rope automatic wire-paying device to achieve:

[0039] S1: When processing the metal wire 4, the winch 2 is locked, the processing equipment 5 draws the wire, and the moving wheel 31 rises;

[0040] S2: When the driving wheel 31 rises to the upper probe 81, the PLC receives a signal, the processing equipment 5 stops working, and the winch 2 is released;

[0041] S3: The moving wheel 31 drives the slider 10 to descend under the action of gravity, and the winch 2 releases the wire. When the slider 10 descends to the lower probe 82, the slider 10 stops descending, the winch 2 is locked, and the processing equipment 5 starts working.

[0042] Working principle: When the induction plate 7 moves to the upper probe 81, the upper probe 81 gives a PLC signal, the winch 2 is turned on, the processing equipment 5 is turned off, and the moving wheel 31 drives the slider 10 to descend under the action of gravity to realize wire release. When the moving wheel 31 drives the slider 10 to descend to the bottom end under the action of gravity, the induction plate 7 moves to the lower probe 82 and gives a PLC signal. The PLC controls the winch 2 to lock, and at the same time the processing equipment 5 is turned on. The processing equipment 5 reels in the wire and pulls the metal wire 4 into the equipment. As the metal wire 4 enters the processing equipment 5, the moving wheel 31 is pulled up. As the moving wheel 31 rises to the top and the induction plate 7 moves to the upper probe 81, the above process is repeated.

[0043] The technical effect of the present invention is: the length of the wire pay-off can be controlled by utilizing the wire pay-off structure 3, and the length of each wire pay-off can be realized by adjusting the distance between the moving wheel 31 and the fixed wheel 32, which is convenient for adjustment. Compared with traditional CNC, the mechanical method is easier to use and is conducive to reducing production costs.
