[0002] At present, the residual torsion value of the finished steel cord cannot be greater than the allowable range. If it is greater than the allowable range, it can only be scrapped. Therefore, we need to test the residual torsion value of the finished steel cord.

[0060] Working principle: When the steel cord I-shaped wheel is manually put on the front conveyor 1 and transported to the first station of the intermediate conveyor 2 closest to the rear conveyor 3, the actuator of the positioning wheel blocking device 72 extends to block the steel cord I-shaped wheel, and the fourth lifting actuator 31 and the fifth lifting actuator 32 in the jacking and rotating device 4 rise to lift the steel cord I-shaped wheel, and then the actuator of the positioning wheel blocking device 72 is reset; after the wheel number is manually identified by a scanner, a certain length of the steel cord head is pulled out and placed on the two lower notched pay-off forward and reverse induction wires on the wire arrangement device. Between rollers 1 and 2 and between wire-clip rollers 1 and 2 on the fixed tensioning wire clamping device 7, the length of the steel cord pulled out exceeds the position of the melting head mechanism 8; after the steel cord contacts the wire-clip sensing rod 22 equipped with a liquid level sensor in the fixed tensioning wire clamping device 7, the third parallel cylinder 11 of the fixed tensioning wire clamping device 7 is closed, so that the wire-clip roller 1 14 and the wire-clip roller 2 15 clamp the steel cord; then the first lifting actuator 24 of the melting head mechanism 8 descends, and the opening and closing actuator 26 is closed to melt the steel cord, and after the melting is broken, the melting head mechanism 8 is reset. The above actions are repeated on the steel cord I-shaped wheels of the other first stations, and when all are in place, the intermediate conveyor 2 stops working. After the steel cord melt heads on the steel cord I-shaped wheels of the first stations are processed, they wait at the standby point for the traction rotating wire clamping device 6 to move to the wire clamping point and clamp the wire at the same time, and the opening and closing actuator 39 is closed (at the beginning of work, the traction rotating wire clamping device 6 must be reset to the origin, and after resetting, it moves along the linear guide rail 5 to the standby point. The original opening and closing actuator 39 is in a horizontal position and the clamping claw 40 is in an open state). After the steel cord is clamped, the traction rotating wire clamping device 6 clamps the steel cord and moves toward the bending point, while the third parallel cylinder 11 of the fixed tensioning wire clamping device 7 is opened. At the moment of walking, the I-shaped wheels on the four first stations sense whether the I-shaped wheels should rotate forward or reverse to pay out the wire through the lower notched forward and reverse sensing wire rollers one and two and the sensors installed directly below the forward and reverse wire rollers one and two to pay out the wire, while ensuring synchronization with the traction speed. (Some of the I-shaped wheels at the four first workstations may rotate forward or reversely.) After the pulling and rotating wire clamping device 6 moves to the bending point, the second rotating actuator 35 rotates the opening and closing actuator 39 and the clamping jaws 40 to the lower vertical position, and then the second lifting actuator 28 with a pressure regulating device in the bending device 10 rises with the bending concave template 29, thereby bending the steel cord, and then the bending device 10 is reset.The traction rotating wire clamping device 6 clamps the bent steel cord back to the residual torsion detection point, and the steel cord I-shaped wheel is synchronously wound. After reaching the detection point, the third lifting actuator 41 in the residual torsion detection device 9 rises. After reaching the position, the first parallel cylinder 43 and the second parallel cylinder 60 in the flexible manipulator assembly and the induction plate manipulator assembly are closed to clamp the bent steel cord, and then the clamping claw 40 in the traction rotating wire clamping device 6 is opened. After the third lifting actuator 41 in the residual torsion detection device 9 is lowered into place, the second rotating actuator 3 in the traction rotating wire clamping device 6 is 5 After the opening and closing actuator 39 and the clamping claw 40 are rotated to the original horizontal position, they are returned to the standby position to wait for the next round of operation. At the same time, the third lifting actuator 41 in the residual torsion detection device 9 rises again. After reaching the position, the flexible manipulator assembly clamps the bent steel cord and slowly opens it. The steel cord begins to detect residual torsion. The sensing bar 59 equipped with a liquid level sensor senses the residual torsion release direction of the detected steel cord, and then the motor 55 controls the release until the residual torsion of the steel cord is completely released and no longer contacts the sensing bar 59 equipped with a liquid level sensor, and the motor 55 stops rotating. The number of residual torsion turns can be recorded only by the motor 55. Embodiments 1 and 3 of the present application are technical solutions for recording the number of residual torsion turns by a single motor 55; this process can also be that the motor 55 and the corresponding photoelectric switch can record the number of residual torsion turns at the same time. Embodiment 2 of the present application is a technical solution for simultaneous detection. After all the inspections of the four steel cord I-shaped wheels are completed, the first parallel cylinders 43 of the induction plate manipulator assembly are all opened, and the first rotating actuator 30 of the lifting and rotating device 4 in the positioning and releasing device starts to work to reel in the wire. At the same time, the induction baffle rod 59 equipped with a liquid level sensor is reset, and the entire residual torque detection device 9 is also lowered and reset at the same time, waiting for the next inspection.
