Abstract
The utility model relates to an air jet loom prevents single latitude control system, detect the head including 2 woofs, current -limiting resistor R3, relay J1, freewheeling diode D1, and two NPN type triode amplifier Q1, Q2, signal sampling resistor R1, R2, output end control air jet loom parking equipment, this woof of its characterized in that detects the head and is piezoceramics IC1, piezoceramics IC1 is not receiving the external force extrusion 10V level output occasionally that rubs, become the 0V current potential when receiving external force friction extrusion, can rub when every woof process piezoceramics IC1 produces 0V level signal, air jet loom normal operating, if level signal did not become 10V when the woof did not rub piezoceramics IC1, actuation of relay J1 and then output circuit switch on, drive air jet loom parking equipment.
Description
Technical field
The utility model relates to field of textiles Machinery Control System, particularly relates to the anti-single control system for woof of a kind of air-jet loom.
Background technology
DOUBLE WEFT FABRIC because of the clear rich lattice of its woven design full, it is better-than-average garment material, every latitude is two weft yarns, because garment material requires stricter, this just requires that two weft yarns can not lack, otherwise reduce to defective cloth, degradation have impact on company's benefit, because 2 bobbin weft yarns are when 1 storage latitude guide eye merges together, there will be broken yarn, unwinding yarn stop and the sticky connection stop of filoplume etc. there will be single latitude situation, and former single latitude controller is lever switch formula, only have yarn to break completely and could drive parking, weft yarn stops that the situation of class cannot detect.It is knitted weft accumulator because of weft yarn by the spray of rotating speed about 1400 turns and to be drawn by another root weft yarn and only have a weft yarn on the attachment of another velamen of delivery, the normal illusion of weft yarn is caused to spinner, thus weave a large amount of defective cloth, equally also can't resolve this difficult problem with the photoelectric type detector of moral cotton research and development again afterwards.
Under this background, study a device, the device of energy Timeliness coverage weft yarn broken yarn, seems particularly important.
Utility model content
For the technological deficiency that prior art exists, the anti-single control system for woof of a kind of air-jet loom described in the utility model can Timeliness coverage weft yarn broken yarn, and drives air-jet loom lugs immediately.
The utility model relates to the anti-single control system for woof of a kind of air-jet loom, comprise 2 weft examining heads, current-limiting resistance R3, relay J 1, sustained diode 1, and two NPN type triode amplifier Q1, Q2, sample of signal resistance R1, R2, output controls air-jet loom lugs, it is characterized in that this weft examining head is piezoelectric ceramics IC1, piezoelectric ceramics IC1 has 10V level to export when not being subject to external force extrusion friction, 0V current potential is become when being subject to external force friction and Extrusion, to rub through piezoelectric ceramics IC1 produce 0V level signal when often propping up weft yarn, air-jet loom normally runs, if weft yarn does not rub, during piezoelectric ceramics IC1, level signal becomes 10V, relay J 1 adhesive and then output circuit conducting, drive air-jet loom lugs.
The relay J 1 that the utility model relates to be auxiliary reclay or other can realize the relay of snap action.Relay J 1 is equipped with closure state indicator lamp DD, and indicator lamp DD can be light emitting diode.
Advantage: working stability after the utility model installation and debugging, no matter what situation of yarn, only otherwise the ceramic eye of friction piezoelectric ceramics will stop immediately, prevents single latitude from source, efficient more than 99%.The utility model installs simple, low, anti-interference strong, the working stability of cost, and spinner does not need training, and above-described staplings yarn and various stop can accurate stoppings.
Accompanying drawing explanation
Fig. 1: the utility model controls schematic diagram.
Detailed description of the invention
The utility model detailed description of the invention is provided below in conjunction with accompanying drawing:
As shown in the figure, the utility model relates to the anti-single control system for woof of a kind of air-jet loom, to rub through piezoelectric ceramics IC1 produce 0V level signal when often propping up weft yarn, the relay J 1 of output circuit is in off-state, the air-jet loom lugs that output controls then are failure to actuate, and air-jet loom normally runs; Otherwise during piezoelectric ceramics IC1, level signal becomes 10V if weft yarn does not rub, relay J 1 adhesive and then output circuit conducting, the air-jet loom lugs that drive output controls, air-jet loom quits work, and staff can investigate parallel situation.By this utility model, occur that weft yarn broken yarn, unwinding yarn stop and filoplume is sticky and join single latitude situations such as stop, can automatic stopping be realized.
Claims (3)
1. the anti-single control system for woof of air-jet loom, comprise 2 weft examining heads, current-limiting resistance R3, relay J 1, sustained diode 1, and two NPN type triode amplifier Q1, Q2, sample of signal resistance R1, R2, output controls air-jet loom lugs, it is characterized in that this weft examining head is piezoelectric ceramics IC1, piezoelectric ceramics IC1 has 10V level to export when not being subject to external force extrusion friction, 0V current potential is become when being subject to external force friction and Extrusion, to rub through piezoelectric ceramics IC1 produce 0V level signal when often propping up weft yarn, air-jet loom normally runs, if weft yarn does not rub, during piezoelectric ceramics IC1, level signal becomes 10V, relay J 1 adhesive and then output circuit conducting, drive air-jet loom lugs.
