Control method for operation of stranding machine

Abstract

The invention relates to a control method for operation of a stranding machine. The stranding machine comprises a yarn unwinding mechanism, tension adjusting mechanisms, a traction mechanism, a yarn arrangement mechanism, a winding mechanism and a PLC in sequence, wherein the PLC carries out real-time collection on numerical values of displacement sensors of the n tension adjusting mechanisms, signals are controlled to be sent to yarn unwinding motors corresponding to the displacement sensors to enable the rotating speeds of the yarn unwinding motors to be increased or be reduced according to increase or decrease of the numerical values of the displacement sensors until the numerical values of the displacement sensors are originally-collected values, the real-time rotating speed of a yarn winding motor can be obtained in the mode that the real-time stranding length minus the real-time position of a yarn arrangement shaft is a numerical value, and then the rotating speed can be obtained by dividing the numerical value by the single-circle yarn winding length, and the real-time rotating speed of a yarn arrangement motor can be obtained by dividing the real-time displacement value of the yarn arrangement shaft by the mechanical screw pitch of a lead screw. Compared with the prior art, the control method for operation of the stranding machine has the advantages that when the control method for operation of the stranding machine is adopted, when the stranding machine is in the process of operation, tension of stranded yarn can be kept to be constant all the time, the situation that the yarn arrangement mechanism and the winding mechanism can work in a coordinated and stable mode can be ensured, and the degree of automation and the degree of intelligence are high.

Description

technical field [0001] The invention relates to a control method for the operation of a plying machine. Background technique [0002] The steel wire braided hose is composed of rubber compound and twisted steel wire. Its quality depends on the quality of the twisted steel wire in addition to the rubber compound formula. The plying steel wire generally needs to be plyed before weaving, and the plying function is a device that combines multiple strands of metal wires. The quality of the steel wire plying directly affects the quality of the hose. [0003] Common plying machines generally include a pay-off mechanism, a wire-arranging mechanism and a winding mechanism. The pay-off mechanism can output multiple metal wires, the wire-arranging mechanism can combine metal wires with the same tension into one strand, and the winding mechanism can The wire is wound onto the spool. In order to ensure that the tension of the wire is the same before and after, it is often necessary to ...
