Description
Technical field
The invention belongs to electromechanical integration technology area, it is related to a kind of tricot machine control device, especially a kind of tricot machine
Yarn guiding chase comb rectifys quasi- control device certainly.
Background technology
The yarn guiding chase comb of tricot machine is dismounted in the reason such as entried because of upper machine debugging, plain maintenance, Replacement procedure, machine
Afterwards, it is required for re-starting the strong quasi- work of yarn guiding chase comb, i.e., when sley point and groove pin are in same plane, allows warp knit to comb
Sley point on comb and the groove pin on needle-bar are in uniform one evenly distributed every one, and require every sley point both sides with its left and right
Hold yarn gap between adjacent groove pin equal.
At present in actual production, the strong quasi- work of tricot machine yarn guiding chase comb is all by machine repair personnel's hand shaken or slow train
Crawl main shaft is in same plane by warp knit sley point and groove pin, judges sley point with groove pin with human eye under dead ship condition
Whether rationally, and progressively finely tuned in the controls by manual in gap；But when tricot machine is in open state, warp knit
Yarn guiding chase comb while the transverse shifting of left and right also in swing, sley point can where moment passes through groove pin plane, at all
Offset distance and the direction of warp knit yarn guiding chase comb cannot be judged with human eye, at this moment machine repair personnel can only wipe pin sound with ear
Size, the multiple trial carried out to the left and to the right according to experience could complete to rectify quasi- work after finely tuning.
Because the strong quasi- precision of tricot machine yarn guiding chase comb is fast to the whole manufacturing machine of equipment and cloth cover qualitative effects are very big, but
Lack effective detection instrument and means again at present, sound judging with ear with observing for operating personnel completely, to rectifying quasi- personnel's
Technical merit and operating experience requirement are high, and rectifying quasi- inefficiency and rectifying quasi- precision to ensure.For this state of the art, urgently
One kind need to be developed can effectively reduce artificial dependence, with more high workload efficiency and degree of regulation and under shutdown and open state
The tricot machine yarn guiding chase comb that can voluntarily adjust rectifys quasi- instrument or technological means certainly.
The content of the invention
The purpose of the present invention is directed to deficiencies of the prior art, there is provided one kind may be implemented in shutdown and start shape
The tricot machine yarn guiding chase comb that can be voluntarily adjusted under state from rectify quasi- control device, by cross the pin moment obtain sley point with
The relative position image of groove pin, via drawing the deviation data of the two after Image Information Processing, and sends control to master control system
Instruct to be rapidly completed the strong quasi- work of yarn guiding chase comb, manpower can be saved and human error is eliminated, improve strong quasi- precision and work and imitate
Rate.
The purpose of the present invention can be realized by following technical solution：A kind of tricot machine yarn guiding chase comb is filled from quasi- control is rectified
Put, be installed on tricot machine machine front position, it is characterised in that：Including detecting the encoder of Spindle rotation angle positional information, obtaining
Pin moment warp knit sley point and groove pin copline location drawing picture acquisition module high-definition camera, contain at embedded image algorithm
Reason module and the Terminal Control Element of wireless data sending sending module and the wireless data sending in tricot machine master control system are received
Module.Its operation principle is：No matter whether tricot machine is in shutdown or open state, as long as the angle being installed on tricot machine main shaft
The spindle angular angle value that position sensor, i.e. encoder are detected can characterize warp knit sley bar and be put down altogether in strict with needle-bar groove pin
During the relation of face, the microcontroller on Terminal Control Element starts high-definition camera and obtains warp knit sley point and needle-bar groove immediately
Relative position image between pin, and it is relative to quickly recognize sley point by the Processing Algorithm that image algorithm processing module is embedded
The position deviation direction of groove pin and offset distance, information passes through wireless data sending to the microcontroller on Terminal Control Element accordingly
Sending module sends guide bar of warp knitting machine and rectifys quasi instruction, and the instruction is obtained by wireless data sending receiver module and is assigned to warp knit owner
Control system, the strong quasi- fine setting of tricot machine yarn guiding chase comb is completed by tricot machine master control system by instruction；The programmable functionality is automatic
Circulation is performed, until offset distance is less than default threshold values.
Further, the microcontroller on the Terminal Control Element is by the ARM chip structures comprising abundant Peripheral Interface
Into, the task coordinate that it is mainly realized and Terminal Control Element is connected between each functional module and management, while terminal control list
Unit includes LCD display.
Further, described image algorithm processing module is inlaid on Terminal Control Element in the form of hardware, its actuator
Part is by possessing high-speed floating point computing and the digital signal processor DSP chip realization of rich image treatment function library, image procossing
Completed in long-range local terminal control unit.
Further, described image algorithm processing module can run on the work in warp knit master control system in software module form
On control machine, the bulk transfer of view data, figure are completed with wireless data sending receiver module using the wireless data sending sending module of high speed
As treatment is completed in central warp knit master control system.
Further, sley point and the sign of groove pin position deviation distance are used in described image algorithm processing module
Offset distance is measured with respect to the ratio value of a needle gage, to realize the general applicability to different machine tricot machines.
Further, the tricot machine yarn guiding chase comb rectifys quasi- control termination condition from the automatic of quasi- control device is rectified, that is, be
System sets threshold values as 2% needle gage.
The present invention compared with prior art, with advantages below and effect：1st, the static state being capable of achieving under stopped status is automatic
The dynamic under accurate and open state is rectified from standard is rectified, adjusts engine efficiency high；2nd, it is real-time based on sley point and groove pin relative position image
Treatment, static state is strong accurate consistent with the strong accurate examination criteria of dynamic, the high precision and stabilization of detection and strong standard；3rd, have there is provided one kind
The accurate measurement of effect and strong quasi- means, thoroughly break away from the strong quasi-full of tricot machine yarn guiding chase comb by human eye and traditional hand of ear
Work pattern.
