Embodiment Construction

[0018] In order to illustrate the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0019] see figure 1 , figure 1 Shown is the flow chart of the method for the PLC controller 1 of the present invention to control the line speed. The PLC controller 1 includes:

[0020] Execute step S1: calculate the winding time t of the nth layer n , to complete the precise time predictive control of the nth layer; wherein, the winding time t n According to the number of coils M of the nth layer n and the radius R of the nth layer n Calculate the bus length L of the nth layer n , followed by the bus length L of the nth layer n Divided by the constant linear velocity v. Said n is any natural number value.

[0021] Execute step S2: when the winding time t of the nth layer n After the operation is completed, the layer is changed...

Abstract

Provided is a PLC controller. The PLC controller comprises the steps of step S1, calculating the winding time tn of an nth layer, step S2, instantly carrying out layer change after operation for the winding time tn of the nth layer is accomplished, starting winding an (n+1)th layer , step S3, calculating the winding time tn+1 of the (n+1)th layer, step S4, calculating driving efficiency fn+1 of a frequency converter aiming for the (n+1)th layer, and step S5, achieving winding with a constant wire speed v by using the frequency converter to control a motor to rotate according to the fn+1. A winding machine with the PLC controller has the advantages of being capable of achieving constant-wire-speed control, capable of achieving high-speed winding of wire products, and capable of accurately calculating the time of the layer change of the (n+1)th layer, improving reliability due to contactless control, prolonging the service life due to contactless control, and being capable of achieving winding of different objectives, stable in winding process and good in comprehensive performance.

Description

technical field [0001] The invention relates to the technical field of automation equipment and its automation control, in particular to a PLC controller and a winding machine with the PLC controller. Background technique [0002] At present, there is no variable frequency drive technology for winding machines, and there is a lack of high-precision constant line speed winding realization methods. There is no specific control program for adaptively controlling output variable frequency drive signals to achieve constant line speed with changes in winding radius. [0003] Therefore for the existing problems of the prior art, the designer of this case actively studies and improves by virtue of years of experience in this industry, so a kind of PLC controller of the present invention and a coil winding machine with the PLC controller have been arranged. Contents of the invention [0004] The present invention is aimed at the defects in the prior art that the high-precision cons...
