Abstract

The invention provides a multifunctional comprehensive measuring and monitoring instrument for detecting a cotton yarn, which is provided with an ultraviolet emitter and an ultraviolet receiver. The ultraviolet emitter and ultraviolet receiver are respectively arranged at both sides of the cotton yarn. The ultraviolet receiver is connected with an input end of an amplifying circuit, an output end of the amplifying circuit is connected with an input end of an A/D converter, an output end of the A/D converter is connected with an input end of a control circuit. The output end of the control circuit is connected with a cutting mechanism. The cutting mechanism can cut the cotton yarn according to the command sent by the control circuit and sends a connecting requirement to an upper computer. The amplifying circuit, the A/D converter and the control circuit are connected with a power supply. The multifunctional comprehensive measuring and monitoring instrument for detecting the cotton yarn detects the yarn diameter of, the impurities contained in and color of different yarns and judges and processes the yarns, thereby effectively reducing the device cost and the debugging workload and improving the device efficiency and the product quality.

Description

Be used to detect the multifunctional comprehensive measurement and control instrument of cotton yarn

Technical field

The invention belongs to the electronic measurement and control technical field, be specifically related to a kind of multifunctional comprehensive measurement and control instrument that is used to detect cotton yarn.

Background technology

In spinning and textile industry; In order to improve the quality of products, usually need be, variegatedly detect judgement to the cotton yarn thickness in collinear footpath not, impurities, and inappropriate yarn is carried out shear treatment; General thickness and impurity, the employing ccd sensor that adopts the high frequency capacitance method to detect cotton thread detects variegated during observing and controlling; This kind equipment cost height, debugging work load is big, and usually because of receiving the influence of aspects such as variation of ambient temperature, humidity variation, airborne dust changes of contents, the strong and weak variation of light; And the operate as normal of the equipment of obstruction; Greatly reduced efficiency of equipment and product quality, the present invention is exactly the deficiency to original measuring and controlling equipment, adopts new observing and controlling principle to make with technology.

Summary of the invention

The technical matters that the present invention solves: a kind of multifunctional comprehensive measurement and control instrument that detects cotton yarn is provided; Utilize UV sensor that line footpath thickness, impurities, the color of different cotton yarns are detected also judgment processing; Equipment cost and debugging work load be can effectively reduce, plant efficiency and product quality improved.

The technical scheme that the present invention adopts: the multifunctional comprehensive measurement and control instrument that is used to detect cotton yarn; Have actinolyte and ultraviolet receiver; Said actinolyte and ultraviolet receiver are divided into the cotton yarn both sides, and said ultraviolet receiver is connected with input amplifier, and said amplification circuit output end is connected with the A/D converter input end; Said A/D converter output terminal is connected with the control circuit input end; Said control circuit output terminal is connected with cutting mechanism, and the instruction that said cutting mechanism sends according to control circuit can be cut off cotton yarn and sent the wiring request to host computer simultaneously, and above-mentioned amplifying circuit, A/D converter and control circuit all are connected with power supply.

Wherein, Said ultraviolet receiver is voltage signal with the conversion of signals that receives and after the amplifying circuit processing and amplifying, send high-speed a/d converter to convert digital signal into; High-speed a/d converter is delivered to control circuit with digital signal; Said control circuit compares the data of digital signal that receives and setting and instruction is sent to cutting mechanism, and said cutting mechanism can be cut off cotton yarn and send the wiring request to host computer according to instruction.

The present invention's advantage compared with prior art:

1, utilize UV sensor simultaneously to the line of cotton thread footpath thickness, impurity, variegatedly detect and control, reduced the sensor kind, and can reduce environmental change measuring the influence of control;

2, utilize high-speed, high precision A/D converter and control circuit that signal is changed and judgment processing, can realize the cotton yarn information of 20 meter per second speed walking is followed the trail of;

3, through control circuit software programming and function setting, man-machine conversation be can realize, and, device intelligenceization, digitizing made the directly automatic measurement and the setting of data of new model cotton; Simultaneously, significantly reduce debug time and the workload of equipment, make equipment have very strong adaptability, dirigibility new product;

4, the components and parts selected for use of equipment are general, cheap, and the cost that circuit is simple, greatly reduce equipment is convenient to implement; The usage quantity of a spinning equipment has about tens to 100, and the fund of saving is very considerable.

Description of drawings

Fig. 1 is a structural principle synoptic diagram of the present invention.

Embodiment

Below in conjunction with accompanying drawing 1 a kind of embodiment of the present invention is described.

Be used to detect the multifunctional comprehensive measurement and control instrument of cotton yarn; Have actinolyte 1 and ultraviolet receiver 2; Said actinolyte 1 is divided into cotton yarn 3 both sides with ultraviolet receiver 2, and said ultraviolet receiver 2 is connected with amplifying circuit 4 input ends, and said amplifying circuit 4 output terminals are connected with A/D converter 5 input ends; Said A/D converter 5 output terminals are connected with control circuit 6 input ends; Said control circuit 6 output terminals are connected with cutting mechanism 7, and the instruction that said cutting mechanism 7 sends according to control circuit 6 can be cut off cotton yarn 3 and sent the wiring request to host computer simultaneously, and above-mentioned amplifying circuit 4, A/D converter 5 all are connected with power supply 8 with control circuit 6.

Principle of work: utilize ultraviolet ray that thickness, impurity, the more sensitive physical characteristics of variegated variation of cotton yarn 3 are detected; Ultraviolet ray receiver 2 is the correspondent voltage signal with thickness, impurity, the variegated information translation of the cotton yarn that receives 3; Voltage signal send high-speed a/d converter 5 to convert digital signal into after amplifying circuit 4 processing and amplifying, and high-speed a/d converter 5 is delivered to control circuit 6 again with digital signal and carried out comparing judgement with the data that are provided with, if in the normal range of setting; The control shear signal is invalid; Cutting mechanism 7 is failure to actuate, if not in normal range, then sends shear signal control cutting mechanism 7 and cuts off cotton yarn 3; Send the wiring request to host computer simultaneously, automatically reset then.

The foregoing description is preferred embodiment of the present invention, is not to be used for limiting practical range of the present invention, so all equivalences of being done with the said content of claim of the present invention change, all should be included within the claim scope of the present invention.
