Embodiment 1

[0020] The take-up motor 1 is connected to the take-up reducer 2, and a take-up encoder 3 is installed on the take-up reducer 2. The take-up encoder 3 is used to detect the angle and speed. The take-up encoder 3 is coaxial with the top of the take-up reel Rotate, the pulse signal sent by the take-up encoder 3 is sent to PLC7, and the PLC can convert the pulse signal into the speed and rotation angle of the take-up reel through the compiled user program, and calculate the line speed, and output the analog after D / A conversion The voltage signal is sent to the frequency converter 10, and the frequency converter 10 controls the wire-arranging motor 9 to arrange the wires.

[0021] A cable encoder 13 is installed on the end of the screw 12 connected to the cable reducer 11. The cable encoder 13 is used to detect the position. The cable encoder 13 rotates coaxially with the screw 12. The output signal of the cable encoder 13 Connected to the switch input terminal of the PLC, with t...

Embodiment 2

[0024] The above-mentioned control system is used to control the winding of the aluminum-clad steel wire. The specific method is: during the operation of the aluminum-clad steel wire winder, when the aluminum-clad steel wire product 4 wound up is wound on the left end surface of the take-up reel 5 (at this time The set commutation position coordinate value is equal to the actual position coordinate value, that is, the commutation signal is generated), the take-up encoder 3 starts to detect the rotation angle of the take-up reel, when the rotation angle is at the set "stop angle" (through the text When the editor sets the "stop angle" to 223°), control the speed of the wire-arraying motor 9 (variable frequency motor) to 0 to ensure that the aluminum-clad steel wire is fully filled with the hypotenuse vacancy 6 left on the boundary end face of the take-up reel; After the end faces are aligned, reverse operation. In order to ensure that the wires do not overlap after the reverse, ...

Abstract

The invention relates to the field of wire arrangement control, and discloses a wire arrangement control method for a coiling machine. When a coiled product is coiled to two end faces of a coiling disc and the wire arrangement direction needs to be switched, different given values are applied to a wire arrangement motor in a set coiling disc rotating angle range, and the wire arrangement velocity is changed according to the rules so that the aluminum clad steel wire product is coiled regularly and arranged uniformly at two ends of the coiling disc. The control method is simple and reasonable; the rotating velocity of the controlled wire arrangement motor is measured as 0 in a set 'stop angle' range through a coder and a programmable logic controller (PLC) when the coiled product is coiled to the end faces of the coiling disc; and after the coiled product is arranged regularly on the end faces of the coiling disc, the wire arrangement velocity of the controlled wire arrangement motor is 2 times original velocity in a set 'quick arrangement angle' range, so wire superposition after the coiling disc rotates for one circle is prevented. Particularly, the control method for the wire arrangement velocity at the steering position of the aluminum clad steel wire coiling machine has high control precision, and prevents wire superposition when the wire is coiled to the boundary of the coiling disc.

Description

technical field [0001] The invention relates to the field of wire arrangement control, in particular to a control method and a control system for an aluminum-clad steel wire winder. Background technique [0002] Aluminum-clad steel wire is mainly used in power transmission and distribution, electrified railway, post and telecommunications, ground detection and other fields, such as good conductor overhead line, large-span transmission line, optical fiber composite overhead ground wire (OPGW), anti-ice and snow conductor, electrified railway load bearing Suo and so on. In the aluminum-clad steel wire continuous cladding production line, it is an important process to use a winding machine to wind and arrange the products neatly. The current winding speed control method of the winding machine is: every time the winding reel rotates once, it should move laterally at a distance equal to the product width. When the cable reaches the two ends of the reel, control the reversing of...
