Control method of stranding machine, and stranding control system

Abstract

The invention discloses a control method of a stranding machine, and a stranding control system. The method comprises the steps of: receiving host operation efficiency through a host control device, and controlling the operation of a stranding motor according to the host operation efficiency, wherein the host operation efficiency is the operation efficiency of the stranding motor; receiving an input electronic gear ratio by a pick-up control device, and controlling the operation of a pick-up motor according to the input electronic gear ratio; calculating the operation efficiency of a wire arrangement motor by a wire arrangement control device according to the host operation efficiency, and controlling the operation of the wire arrangement motor according to the operation efficiency of thewire arrangement motor; and receiving a preset tension value through a rolling control device, and performing closed loop adjustment according to the preset tension value and a collected tension signal, so that the rotation speed or torque of a rolling motor is within a preset range. Through the above manner, integrated control of the pick-up, wire arrangement and rolling can be realized, the costis reduced, and the stranding distance can be adjusted in real time to improve the rolling quality.

Description

technical field [0001] The present application relates to the technical field of integrated control, in particular to a control method of a stranding machine and a stranding control system. Background technique [0002] Stranding machine is a kind of wire that can be widely used in various soft / hard conductor wires (such as copper wire, enameled wire, tinned wire, copper-clad steel or copper-clad aluminum, etc.) wire or winding wire, etc.); the principle of the twisting machine is that the copper wire passes through the twisting bow on the twisting machine, and the twisting bow makes each single copper wire spirally wound together through circular motion; different specifications, different After a certain number of copper wires are twisted together in a certain order and lay length, they become a conductor with a larger diameter. This twisted conductor is much softer than a single copper wire of the same diameter. The wire bending performance is also better. [0003] The ...

Problems solved by technology

[0003] The process integration control system of the stranding machine is a small stranding machine system, which consists of a complete stranding machine process integration control system composed of a liquid crystal display, a screw structure, a stranding motor, a wire arranging motor, a drawing motor, and a winding motor; The existing stranding process integration is realized by a Programmable Logic Controller (PLC, Programmable Logic Controller) and multiple control modules, the timeliness of data is low, the volume is large, the mechanical structure is complicated, the installation of the system is difficult, and the existing technology The control stability of the twisted wire motor, lead-in motor, wire-arrangement motor and winding motor is poor, and it cannot achieve better process integration control

[0004] The control of the cable motor occupies an important position in the stranding process. The traditional cable motor is not allowed to adjust the parameters during operation, and the parameters must be adjusted after the system is shut down. This method reduces production efficiency and control flexibility; When the pitch needs to be adjusted, the mechanical gear must be replaced manually, resulting in an increase in labor costs; the existing strand control production efficiency is low, and the mechanical gear needs to be replaced manually to meet different process requirements. The mechanical structure is complicated, the installation is difficult, the service life is short, and the volume With heavy weight, large space resources, high cost, low cost performance, can not reflect the optimal cost, low flexibility, and poor timeliness of data transmission, so in the face of these disadvantages, the entire process needs to be improved to achieve better process integration control
