Abstract

The invention relates to an electronic yarn clearer which comprises a yarn detection device and a defect cutting device. The yarn detection device comprises a light transmitter and a light receiver, the light transmitter is aligned with the light receiver to transmit light beams with the high penetrability, the light receiver is a photoelectric sensor, receiving time intervals of the photoelectric sensor can be set, the photoelectric sensor is connected with a NOT gate circuit, and circuits of the photoelectric sensor, the NOT gate circuit and the defect cutting device are connected in series. According to the electronic yarn clearer, the propagation velocities of the light in different media are different, and the penetrability of the light is high, so that defect signals are accurately transmitted, the defect cutting device is controlled, influences of the outside are small, and the electronic yarn clearer is accurate and efficient.

Description

A kind of electronic yarn clearer

Technical field

The present invention relates to a kind of textile machine checkout equipment, especially, is a kind of electronic yarn clearer.

Background technology

Electronic yarn clearer is in textile industry, it is the electro-mechanical device for detecting and cut off yarn defect, utilize sensor that the thickness of yarn is changed and converts the corresponding signal of telecommunication to, signal is passed to after treatment and is controlled executing agency, finally control executing agency and cut off exceeding the yarn defect of setting specification, remove the influential yarn defect of product quality.Existing electronic yarn clearer mainly contains two kinds of photo-electric type and condenser types, all take electronic technology as basis, to realize detecting and excision yarn fault, the photoresistance amount that wherein photoelectric type yarn clearer mainly relies on luminous tube and receiving tube to detect yarn shading line reflects that the side of yarn changes and yarn fault, such photoelectric type yarn clearer is easy to be subject to the impact of the factors such as flyings dust, light variation, flyings dust can affect generation and the reception of light, light variation can make rub-out signal increase, and affects production efficiency.

Summary of the invention

For the problems referred to above, the object of the present invention is to provide a kind of electronic yarn clearer, this electronic yarn clearer can send yarn fault signal exactly, enhances productivity.

The technical solution adopted for the present invention to solve the technical problems is: this electronic yarn clearer, comprise Yarn detection device and fault excision equipment, described Yarn detection device comprises light emitters and light receiver, described light emitters is aimed at described light receiver and is launched the light beam of strong penetrability, described light receiver is the photoelectric sensor that time of reception interval can be set, described photoelectric sensor is connected with a not circuit, and the circuit of described photoelectric sensor, described not circuit and described fault excision equipment is connected in series.

As preferably, described light emitters transmitting X-ray, X-ray penetration power is strong, and that can comparatively concentrate sends optical signal to described photoelectric sensor.

Beneficial effect of the present invention is: above-mentioned electronic yarn clearer in use, first that yarn up to specification is good through the time measurement used of yarn checkout equipment, in the interior sensor of light receiver, set interval time, when yarn process yarn checkout equipment, due to X-ray in air with solid in speed different, when yarn has fault, the time that photoelectric sensor receives light can delay, photoelectric sensor does not receive signal within the set time, without the signal of telecommunication, export to not circuit, not circuit output output forceful electric power signal, now fault cut-off circuit is connected, start working, automatically the fault of excision yam surface, by detecting X-ray, arrive the time difference of photoelectric sensor, control fault excision equipment, this electronic yarn clearer is subject to ectocine little, accurately efficient.

Accompanying drawing explanation

Fig. 1 is the structural representation of this electronic yarn clearer.

Fig. 2 is this electronic yarn clearer part circuit structure schematic diagram.

The specific embodiment

In the embodiment shown in Fig. 1, Fig. 2, this electronic yarn clearer, comprise Yarn detection device 1 and fault excision equipment 2, described Yarn detection device 1 comprises light emitters 11 and light receiver 12, described light emitters 11 is aimed at described light receiver 12 and is launched the light beam 21 of strong penetrability, described light receiver 12 is for arranging the photoelectric sensor 13 at time of reception interval, described photoelectric sensor 13 is connected with a not circuit 4, and described photoelectric sensor 13, described not circuit 4 are connected in series with described fault excision equipment 2 circuit.

Above-mentioned electronic yarn clearer, light beam that described light emitters 12 is sent 21 is X-ray, and X-ray penetration power is strong, and that can comparatively concentrate sends optical signal to described photoelectric sensor, the sensitivity of raising sensor.

In use, during first by yarn up to specification 31 process yarn checkout equipment 1, X-ray is good from being transmitted into reception time measurement used, sets the interval time that light receives in described photoelectric sensor 13 for above-mentioned electronic yarn clearer.When yarn process yarn checkout equipment 1, because the aerial spread speed of X-ray is than faster in solid, so X-ray is when penetrating yarn 31, if yarn 31 does not have fault, photoelectric sensor 13 receives optical signal in setting-up time, and photoelectric sensor 13 transfers optical signal to the signal of telecommunication, the input of not circuit 4 has the signal of telecommunication, after not circuit 4, the output of output no signal, therefore fault excision equipment 2 is not worked; If yarn 31 has fault, the time of X-ray arrival photoelectric sensor 13 can be slightly slow, photoelectric sensor 13 does not receive optical signal in setting-up time, now do not have the signal of telecommunication to export to not circuit 4, not circuit 4 output output electrical signals, now fault excision equipment 2 circuit are connected and are started working, and automatically excise the fault on yarn 31 surfaces.This electronic yarn clearer utilizes the strong penetrating power of X-ray, and X-ray is different from spread speed in yarn at air, by X-ray, is launched with the time difference receiving and is controlled fault excision equipment 2, is affected by the external environment little, accurately efficient.
