A wireless control device and method in a twisting machine

Abstract

The invention belongs to the technical field of machinery, and provides a wireless control device in a pair twister. The wireless control device in the pair twister comprises an external PLC (Programmable logic Controller), two wireless controllers, a main PLC, a take-up frequency converter, a traction frequency converter, a take-up tension sleeve and a meter-counting encoder; the device is controlled according to the method comprising the following steps: firstly, after pressing the external PLC to start a button, carrying out wireless pairing through starting signals of the two wireless controllers and the main PLC; then transmitting set traction speed onto the main PLC through wireless signals; and transmitting the signals into the take-up frequency converter and the traction frequency converter by the main PLC so as to drive working cycle of corresponding frequency converter. The device and the method have the advantages that the mutual transmission and matching of signals and take-up signals are realized through wireless control manner, the existing disadvantage that direct take-up control cannot be carried out on a cradle after a twisted bow is rotated is solved, the transmission stability is good, cables are prevented from being damaged in pair twisting process, and the work efficiency of pair twisting is improved.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a pair twisting machine, in particular to a wireless control device and method in the pair twisting machine. Background technique [0002] Power cables and communication cables are the second pillar products of my country's export products. A large cable is twisted by multiple or pairs of small cables at a certain helical distance to improve the bending resistance of the cable and improve the electronic performance. The anti-interference ability of the signal, so the machine used for twisting is applied. The existing twisting machine generally includes a pay-off mechanism, a take-up mechanism, a traction mechanism and a cradle assembly. The traction mechanism pulls the cable to move, and the cradle The component is installed on the bearing seat, and the cradle component has a twisted bow. Since the twisted bow is rotated, the cradle cannot be directly connected to the control. In or...

[0002] Power cables and communication cables are the second pillar products of my country's export products. A large cable is twisted by multiple or pairs of small cables at a certain helical distance to improve the bending resistance of the cable and improve the electronic performance. The anti-interference ability of the signal, so the machine used for twisting is applied. The existing twisting machine generally includes a pay-off mechanism, a take-up mechanism, a traction mechanism and a cradle assembly. The traction mechanism pulls the cable to move, and the cradle The component is installed on the bearing seat, and the cradle component has a twisted bow. After the twisted bow is rotated, the cradle cannot be directly connected to control. In order to make the signal control accurate, a wireless control method is designed to realize the signal transmission.
