[0003] The utility model provides a switching system for S / N-direction wire stranding of a cantilever single-strand strander. When switching the S / N-direction wire stranding, it is not necessary to rotate the wires on the stranding bow to the other side.

[0004] Technical Solution of the Utility Model

[0005] A switching system for S / N-direction wire stranding of a cantilever single-strand strander is used for a cantilever single-strand strander; the cantilever single-strand strander adopts a PLC control system; the switching system is composed of a connection between the PLC control system, an encoder I installed on the take-up motor of the cantilever single-strand strander, and an encoder II installed on the stranding bow motor of the cantilever single-strand strander. The take-up motor speed of the cantilever single-strand strander is controlled by the encoder I to be V_take-up, and the stranding bow motor speed V_bow is controlled by the encoder II.

[0006] When stranding in the S direction, both the take-up motor and the stranding bow motor of the cantilever single-strand strander rotate forward, and V_take-up < V_bow.

[0007] When stranding in the N direction, both the take-up motor and the stranding bow motor of the cantilever single-strand strander rotate in reverse, and V_take-up > V_bow.

[0008] A switching method for S / N-direction wire stranding of a cantilever single-strand strander is used for switching the S / N-direction wire stranding of a cantilever single-strand strander; the cantilever single-strand strander is equipped with the above-mentioned switching system for S / N-direction wire stranding of a cantilever single-strand strander; the method:

[0009] 1) Set the parameters of the cantilever single-strand strander through the touch screen of the PLC control system, including the rotation direction of the take-up motor of the cantilever single-strand strander, the rotation direction of the wire stranding motor of the cantilever single-strand strander, V_take-up, and V_bow.

[0010] Establish the S-direction wire stranding mode: both the take-up motor and the stranding bow motor of the cantilever single-strand strander rotate forward, and V_take-up < V_bow.

[0011] Establish the N-direction wire stranding mode: both the take-up motor and the stranding bow motor of the cantilever single-strand strander rotate in reverse, and V_take-up > V_bow.

[0012] 2) According to the wire stranding process, when switching the S / N-direction wire stranding is required, perform a one-key switch through the touch screen of the PLC control system.

[0013] The advantages of the utility model are as follows: reasonable design and ingenious conception. Encoders are installed on the take-up motor and the bow motor of the cantilever single-strand strander. By connecting the encoders to the original PLC control system, precise control over the rotational speeds of the take-up motor and the bow motor of the cantilever single-strand strander is achieved. When switching the stranding direction from S to N, the speed difference is cleverly utilized to adjust the wire inlet angle of the wire reel, eliminating the need to rotate the wire reel to the other side.
