Abstract
The invention relates to a novel needle breakage photoelectric sensing and alarming device of and arranged in a large diameter circular knitting machine. The novel needle breakage photoelectric sensing and alarming device comprises a main alarming machine and a plurality of detecting probes; the detecting probes are arranged in outer periphery of a cylinder of the large diameter circular knitting machine, 0.5 to 1cm away form the needlepoint; the detecting probes consist of two parts: an infrared emitter and an infrared receiver; the main alarming machine consists of an amplifying circuit I, a frequency selective circuit, an amplifying circuit II, an A/D converser, a CPU and an alarm. The infrared receiver of the detecting probes is connected with the input end of the amplifying circuit I; the output end of the amplifying circuit I is connected with the input end of the frequency selective circuit; the output end of the frequency selective circuit is connected with the input end of the amplifying circuit II; the output end of the amplifying circuit II is connected with the input end of the A/D converser; the output end of the A/D converser is connected with the CPU, which is also connected with a control system and the alarm of the large diameter circular knitting machine. The invention is able to detect the working status of the large diameter circular knitting machine, and alarms in case of needle breakage.
Description
Technical field
The present invention relates to a kind of circular knitting machine, especially relate to a kind of novel knitting circular knitting machine photoelectricity induction needle-breaking warning device that is installed on the circular knitting machine.Belong to technical field of textile machine.
Background technology
Circular knitting machine is the high-grade knitted machine in numerous Knitting Machinery, is characterized in that yield in unit time is big, the product specification height.Circular knitting machine generally has 1600-3500 root pin, in the course of the work, the broken needle situation can occur, the result who causes is that the blast hole phenomenon appears in cloth cover, if do not handle rapidly, continuous blast hole can occur, cause the generation of substandard products, this flaw is the main blemishes of knitted cloth.At present, the knitting mill generally all is the inspection cloth cover that is not stopped by the operative employee, does not note slightly, will produce substandard products.Therefore efficiency is lower, and in this industry, an operative employee generally can only operate 2～3 machines simultaneously.Therefore, need a kind of can the duty of circular knitting machine the detection,, then report to the police, and point out the broken needle warning device of concrete broken needle position if there is the broken needle situation to take place.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, providing a kind of can detect the duty of circular knitting machine, if the generation of broken needle situation, the then novel knitting circular knitting machine photoelectricity induction needle-breaking warning device of Bao Jinging are arranged.
The object of the present invention is achieved like this: a kind of knitting circular knitting machine photoelectricity induction needle-breaking warning device, it is characterized in that described warning device comprises an alarm host machine and several detection probe, several detection probe are installed in the syringe periphery of circular knitting machine, are 0.5-1cm from the distance of needle point.
Described detection probe comprises infrared transmitter and two parts of infrared remote receiver,
Described alarm host machine comprises amplifying circuit I, frequency selection circuit, amplifying circuit II, A/D converter, CPU and alarm, the infrared remote receiver of detection probe links to each other with amplifying circuit I input, the output of amplifying circuit links to each other with the frequency selection circuit input, the frequency selection circuit output links to each other with amplifying circuit II input, amplifying circuit II output links to each other with the A/D converter input, the A/D converter output links to each other with CPU, and CPU links to each other with alarm with the control system of circular knitting machine.
The present invention can detect the duty of circular knitting machine, if there is the broken needle situation to take place, then reports to the police.
Description of drawings
Fig. 1 is the general structure schematic diagram of novel knitting circular knitting machine photoelectricity induction needle-breaking warning device of the present invention.
Fig. 2 is the work block diagram of novel knitting circular knitting machine photoelectricity induction needle-breaking warning device of the present invention.
Fig. 3 is the alarm host machine circuit block diagram of novel knitting circular knitting machine photoelectricity induction needle-breaking warning device of the present invention.
The specific embodiment
Referring to Fig. 1～2, the novel knitting circular knitting machine photoelectricity induction needle-breaking warning device that the present invention relates to mainly is made up of an alarm host machine and several detection probe.Thousands of pins of circular knitting machine all be installed in a metal tub thing around, term is called syringe.Several detection probe are installed in the syringe periphery of circular knitting machine, are 0.5-1cm from the distance of needle point.
Described detection probe comprises infrared transmitter and two parts of infrared remote receiver, and infrared remote receiver links to each other with alarm host machine by connecting line.
Referring to Fig. 3, described alarm host machine mainly is made up of amplifying circuit I, frequency selection circuit, amplifying circuit II, A/D converter, CPU and alarm.The infrared remote receiver of detection probe links to each other with amplifying circuit I input, the output of amplifying circuit links to each other with the frequency selection circuit input, the frequency selection circuit output links to each other with amplifying circuit II input, amplifying circuit II output links to each other with the A/D converter input, the A/D converter output links to each other with CPU, and CPU links to each other with alarm with the control system of circular knitting machine.Alarm host machine also includes display, keyboard, the fetch interface of CF card and USB flash disk and various communication interface.
Operation principle:
The infrared transmitter of detection probe is launched the pulse signal of high frequency, there is pin normally to pass through if run into, then can produce reflective, this heliogram is received by infrared remote receiver, and deliver to alarm host machine by connecting line, the signal that the amplifying circuit I of alarm host machine is faint with this amplifies, the frequency selection circuit frequency-selecting, amplifying circuit II is again after the amplification work, friendship has the AD converter collection to become numerical quantities, after high-speed CPU obtains this digital quantity, by certain algorithm, comprehensively whether the result of calculation of all probe passages judge broken needle, if needle point is disconnected, the infrared light that does not then have reflection, the infrared light that perhaps reflects is very faint, after the CPU integrated treatment, is judged to be broken needle.And by the shutdown of output interface order large circle machine, and report to the police, on the LCD of main frame, point out concrete broken needle position.
