Abstract
A drawing monitoring alarm system for a drawing machine belongs to the technical field of monitoring alarm, can realize real-time monitoring of cotton slivers, and is reliable in quality control. The drawing monitoring alarm system comprises a speed sensor, a programmable logic controller and a display device, wherein the speed sensor is capable of detecting running speed of rollers. The drawing monitoring alarm system is characterized in that the programmable logic controller is connected with the speed sensor and the display device.
Description
Technical field
The utility model belongs to the monitoring, alarming technical field, relates in particular to a kind of draft of drawing frame monitor and alarm system.
Background technology
In textile machine the effect of drawing frame be with 6～8 slivers in course of conveying, utilize the sliver that roller and roller will disperse each other and close and drawing-off, improved the uniformity of sliver and degree of stretching, the depth of parallelism of fiber, and made the fiber of different qualities in sliver, mix more even.
For the drawing frame of no autoleveller, no on-line monitoring, the merging of sliver and drawing-off rely on machine driving to realize fully.And, can only rely on laboratory worker regularly to spot-check the sliver quality and carry out management on the macroscopic view for this important step of sliver quality monitoring.Generally, 3～4 sliver quality of each class's selective examination were calculated with per tour in 8 hours, at least also want the quality of a sliver of ability inspection in two hours, and during this, machine were all the time in running.If machine goes wrong during this period,, will cause the variation of sliver weight, and the spinner can't discover at all as the draw zone belt is loosening a little, roller throws switch etc.Suppose that the machine sliver exporting speed is 400m/min, two hours time, will produce 48000 meters defective sliver, if the problem sliver in time is not found, flow into down together, certainly will will produce more refuse yarn, cause bigger economic loss.
Summary of the invention
The utility model is exactly at the problems referred to above, provides a kind of and can monitor in real time the quality of sliver, the reliable draft of drawing frame monitor and alarm system of quality control.
For achieving the above object, the utility model adopts following technical scheme, the utility model comprises tachogenerator, programmable logic controller (PLC) and the display unit that can detect the roller speed of service, and its structural feature programmable logic controller (PLC) links to each other with tachogenerator, display unit respectively.
As a kind of preferred version, tachogenerator described in the utility model is a plurality of, and each tachogenerator links to each other with programmable logic controller (PLC) respectively.
As another kind of preferred version, tachogenerator described in the utility model adopts the high gear tachogenerator.
In addition, display unit described in the utility model is a touch-screen.
The utility model beneficial effect: (1) the utility model programmable logic controller (PLC) links to each other with tachogenerator, display unit respectively; Adopt electric monitoring to replace original hand inspection, can monitor in real time, the reliable more and reduction cost of labor of quality control the quality of sliver.
(2) the utility model tachogenerator is a plurality of; Can monitor the ruuning situation of a plurality of rollers simultaneously.
(3) the utility model display unit is a touch-screen; Be convenient to show and control.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described further.The utility model protection domain not only is confined to the statement of following content.
Fig. 1 is the utility model electrical diagram.
The specific embodiment
As shown in the figure, the utility model comprises tachogenerator, programmable logic controller (PLC) and the display unit that can detect the roller speed of service, and programmable logic controller (PLC) links to each other with tachogenerator, display unit respectively.
Described tachogenerator is a plurality of, and each tachogenerator links to each other with programmable logic controller (PLC) respectively.
Described tachogenerator adopts the high gear tachogenerator.
Described display unit is a touch-screen.
The utility model can carry out real-time monitoring to the most important drafting link of common drawing frame, monitors in real time as counter extensioin district one, two, three roller speeds (or all important running rollers of drafting link).Monitoring Data is directly imported PLC, by PLC programming, calculates current drafting multiple and back zone drafting multiple (the drafting multiple precision that calculates be not less than ± 0.01), finally shows on touch-screen.When the drafting multiple of drafting multiple that records and setting differs the size that 0.02(should be worth, can be according to user's needs, manually setting on the touch-screen) more than then report to the police and stop the warning clause of corresponding demonstration " dominant draft is overproof " or " back area draft is overproof " on the touch-screen.The user can observe the working order in draft of drawing frame district intuitively.
The utility model is simple in structure, tachogenerator adopts general high gear tachogenerator, response frequency is 33KHz, certainty of measurement is a positive and negative pulse, the tachogenerator probe does not have groove sign and directionality requirement when installing, the backlash of tested gear may diminish to 1.5～2 millimeters, has high resolution ratio and repeatability.Tachogenerator is installed and adjusts easy to operate, detects accurately, and electrical control is reliable, stable, touch-screen is realized human-computer dialogue, and the hidden danger that drawing frame misdraft brings has been eliminated in handled easily and maintenance to a great extent, be practical so far, monitoring device accurately.
Be with being appreciated that, more than about specific descriptions of the present utility model, only be used to the utility model is described and be not to be subject to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can make amendment or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection domain of the present utility model.
