Description
Technical field
The present invention relates to the technical field of a kind of weaving machinery, particularly relate to a kind of be exclusively used in circular weaving machine energy-efficient directly
Rheology frequency decelerating through motor halt control method.
Background technology
General circular weaving machine includes main frame, feeding system of warp, wrap-up, frame；Described main frame includes mair motor, power train
System, organizine Kai Jiao mechanism and picking motion, described picking motion includes visit circle, Xia Menquan, connection post, shuttle and propeller；
Described drive system includes belt wheel, main shaft, bearing；Its host work principle: driven little cam to rotate by motor-driven main shaft,
Again by little cam driven leverage around fixing point reciprocally swinging, finally inside and outside brown belt is driven to do together up and down reciprocatingly by lever end
Motion, by the apertures monofilament being fixed on inside and outside brown belt complete organizine open ship dynamic, by motor controller controls mair motor band
Dynamic drive system, power spreads out of from the center of circle of circular weaving machine, promotes weft yarn shuttle to pass from warp thread Cross Hatch, thus realizes drawing
Latitude action.Circular weaving machine the most on the market, in stopping process, motor slows down naturally, the organizine in deceleration early stage feeding system of warp or latitude
Band easily sheds, and causes scratch tape, and late deceleration makes organizine or the fracture of latitude band owing to deceleration is too fast.
Summary of the invention
Present invention aims to the defect that prior art exists, it is provided that a kind of efficient, energy-conservation circular weaving machine is high
Imitate energy-conservation DC frequency-changing motor sectional speed reducing stopping control method.
For reaching above-mentioned purpose, the present invention uses following technical proposals: circular weaving machine efficient energy-saving dc frequency conversion motor divides
Section speed reducing stopping control method, described circular weaving machine includes main frame, feeding system of warp, wrap-up, frame and DC frequency-changing electricity
Machine controller, described main frame includes direct current variable frequency motor, drive system, organizine Kai Jiao mechanism and picking motion, and motor speed is examined
Surveying device, coordinate direct current variable frequency motor controller that the main shut-down system speed of circular weaving machine is carried out Discrete control, it includes walking as follows
Rapid: S1: motor stopping process is carried out segmentation, according to shutting down required total time and combining built-in in direct current variable frequency motor controller
Segments set and require to establish section tail Velocity Reference point, each distribution period, fast according to time distributed in section and section tail
Functional relationship between degree datum mark, it is achieved to the real-time monitoring of speed in section；S2: motor speed detection device reads in real time works as
Front motor velocity amplitude also feeds back to direct current variable frequency motor controller, and direct current variable frequency motor controller is according to the current motor speed read
Angle value, residing section distribution time and section tail Velocity Reference point calculate the offset of decelerating through motor, give direct current variable frequency motor
Compensate retarding power.
Improve as one: carry out segmentation than by motor stopping process according to electric current mean allocation in step sl so that
Change with setting value in section along with motor speed value declines its decelerating through motor time.
One circular weaving machine efficient energy-saving dc frequency conversion motor sectional deceleration halt control method of the present invention, have employed segmentation
The control of speed reducing stopping, makes to carry out segmentation than by motor stopping process according to electric current mean allocation in step sl so that along with
Motor speed value declines its decelerating through motor time and changes with setting value in section.Shorten downtime, simultaneously in the control of deceleration point
On can achieve the control of secondary track and localization, tail speed, it is achieved shut down deceleration optimized control.It is greatly improved circular weaving machine
Efficiency, intelligent automation and energy-conserving and environment-protective, this system is arranged in efficient energy-saving dc variable frequency motor controller, and its parameter both may be used
Built-in can also revise in the later stage to dispatch from the factory.There is the advantages such as technical ability effect is notable, reduce percent defective, thus reach environmental protection joint
Energy.
In order to make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing the present invention made into
The detailed description of one step.
Accompanying drawing explanation
Fig. 1 is speed reducing stopping rate of acceleration change table of the present invention.
Detailed description of the invention
As it is shown in figure 1, a kind of circular weaving machine efficient energy-saving dc frequency conversion motor sectional deceleration halt control method, described
Circular weaving machine includes main frame, feeding system of warp, wrap-up, frame and direct current variable frequency motor controller, and described main frame includes direct current
Frequency conversion motor, drive system, organizine Kai Jiao mechanism and picking motion, motor speed detection device, cooperation direct current variable frequency motor control
Device processed carries out Discrete control to the main shut-down system speed of circular weaving machine, and it comprises the steps:
S1: motor stopping process carries out segmentation, according to shutting down required total time and tying in direct current variable frequency motor controller
Close built-in segments to set and require to establish section tail Velocity Reference point, each distribution period, according to the time distributed in section and
Functional relationship between section tail Velocity Reference point, it is achieved to the real-time monitoring of speed in section；
S2: motor speed detection device reads current motor velocity amplitude in real time and feeds back to direct current variable frequency motor controller,
Direct current variable frequency motor controller is according to the current motor velocity amplitude read, residing section distribution time and section tail Velocity Reference point meter
Calculate the offset of decelerating through motor, give direct current variable frequency motor and compensate retarding power.
Segmentation is carried out than by motor stopping process in step sl so that along with motor speed value according to electric current mean allocation
Declining its decelerating through motor time changes with setting value in section.In stopping process, motor sectional slows down, deceleration early stage quick deceleration
Organizine in feeding system of warp or latitude band will not be shed, it is to avoid scratch tape is formed, and late deceleration is owing to slowly slowing down, the most anti-
Organizine or the fracture of latitude band are stopped.
