The operation starting signal of the control system is connected to the jacquard independent driving control system, and the loom control system starts the loom spindle motor to be determined by the control signal sent by the jacquard independent driving system. The application provides longer starting time for the jacquard to reach the synchronous rotating speed of the loom, and when the loom is started, the jacquard motor reaches a certain rotating speed, and the jacquard motor is accelerated to the synchronous rotating speed from the rotating speed, so that smaller output torque is required for reaching the synchronous rotating speed than the static state, thereby reducing the configuration power of the motor.
Description
Technical Field
The application belongs to the technical field of electronic jacquard loom, and relates to a control system of an electronic jacquard loom.
Background
The current control scheme of the electronic jacquard adopts a variable frequency system control of an asynchronous motor, a servo motor system and a switch reluctance motor control system to independently drive a jacquard main shaft to move, so that a transmission mode that the traditional jacquard main shaft is connected with the loom main shaft through a commutator and a transmission shaft is replaced. For related technical means, see description in a Chinese patent (publication No. CN 103306000A).
As shown in fig. 1, a system architecture diagram of a control system of an electronic jacquard loom in the prior art is shown. After the loom is started, a signal is transmitted to a jacquard driving control system through a loom transmission encoder, and then the jacquard driving control system controls the operation of a jacquard motor. The control method comprises the following steps:
the jacquard driving control system samples signals of a transmission encoder of the loom and calculates the rotating speed of a motor for driving the jacquard so as to realize synchronous operation of the jacquard and the loom.
Because the loom is started at the heald position generally, in order to obtain larger starting beating-up force, the loom main shaft is started by adopting a triangle connection method of an alternating current asynchronous motor or the quick starting control of other motors, the starting acceleration is large, at the moment, the motion of the jacquard from the heald position to the opening position is a process of gradually increasing the load, and because the servo driver or the frequency converter driving motor is stopped from the rest position to the rated speed, the motor needs larger output torque and is started under the working condition of high speed or heavy load, the jacquard driving motor cannot track the rotating speed of the loom main shaft quickly, the motion positions of the jacquard and the loom main shaft are out of step, and the loom is failed to start weft insertion. To avoid this, the conventional equipment increases the motor power to increase the starting torque. Under the working conditions of larger load and higher speed, the acceleration torque required by normal operation needs to be multiplied, and once the system is in normal operation, the output torque of the motor is reduced more, so that the equipment cost is increased.
Disclosure of Invention
In order to overcome the defects of the prior art, the application aims to provide an electronic jacquard loom control system and an operation control method thereof, so that a jacquard driving motor can overcome larger starting acceleration moment required by rapid acceleration during starting, and the stable starting is synchronous with the rotating speed of a loom main shaft, thereby avoiding step-out.
In order to solve the technical problems and achieve the technical effects, the application is realized by the following technical scheme:
an electronic jacquard loom control system comprises a loom control system, a jacquard independent drive control system and a starting system, wherein the loom control system is used for controlling a loom main shaft drive motor, the jacquard independent drive control system is used for controlling a jacquard drive motor, the starting system is used for controlling the jacquard independent drive control system, and the jacquard independent drive control system is used for controlling the loom control system; the starting system sends a system starting signal to the independent driving control system of the jacquard, and the independent driving control system of the jacquard pre-processes the system starting signal and then sends the system starting signal to the loom control system.
Another object of the present application is to provide an operation control method of an electronic jacquard loom control system, comprising the steps of:
1) After a start control signal button of the starting system is pressed, the independent driving control system of the jacquard machine receives a start signal;
2) The jacquard motor is started to run at a certain speed by the jacquard independent driving control system;
3) When the jacquard motor runs to a set position or rotating speed, the jacquard independent driving control system sends a starting signal to the loom control system, and the loom control system drives the loom main shaft to move after receiving the starting signal;
4) After the loom main shaft runs, the jacquard independent driving control system collects the rotating speed signal of the loom main shaft, and then synchronous running control of the jacquard and the loom is carried out.
Because the independent driving motor of the jacquard machine is started to rotate at a certain angle at a lower speed and reaches a certain rotating speed, the output acceleration torque of the motor during starting can be reduced. The rotation speed of the independent driving motor of the jacquard is calculated by collecting signals of the loom main shaft encoder, and the synchronization of the loom main shaft operation and the jacquard opening is ensured before the weft insertion action of the loom.
The beneficial effects of the application are as follows:
the existing electronic jacquard loom control systems are all connected with loom control systems by operation buttons, and after the loom control systems start loom spindle motors, the jacquard independent driving systems carry out passive synchronous tracking according to the operation of loom spindles. The application provides longer starting time for the jacquard to reach the synchronous rotating speed of the loom, and when the loom is started, the jacquard motor reaches a certain rotating speed, and the jacquard motor is accelerated to the synchronous rotating speed from the rotating speed, and smaller output acceleration torque is needed for reaching the synchronous rotating speed than the static state, so that the configuration power of the motor can be reduced.
