Abstract
The invention provides a weaving machine broken yarn catching device. The weaving machine broken yarn catching device comprises a catching platform which is arranged on one side of a warp yarn conveying plane in parallel, warp yarns are provided with presser sensors for monitoring whether the warp yarns are broken, each warp yarn is correspondingly provided with a catching groove in the catching platform, the two ends of each catching groove are provided with an air nozzle and an extraction opening, the spraying direction of each air nozzle is consistent with the conveying direction of the warp yarns, the spraying quantity of each air nozzle is equal to the extraction quantity of the corresponding extraction opening, and a presser controls each air nozzle. According to the weaving machine broken yarn catching device, pressure intensity on one side of each warp yarn is reduced by means of air flow sprayed through the corresponding air nozzle, the broken yarns enter the catching grooves by being sucked by the air flow, and meanwhile tension of the warp yarns is kept by means of friction between the air flow and the weft yarns and the warp yarns are prevented from flying.
Description
Affiliated technical field
The present invention relates to field of textile machinery, especially, is a kind of broken yarn acquisition equipment that is applicable to loom.
Background technology
Loom is all provided with Warp stop motions, and the object of this device is to survey cracked ends, sends stop sign.Their type: photo-electric type (far infrared detection), stop over posture, point comb is rotary.The stop over postures that adopt at present, its operation principle: stop over frame is contained between the back rest and heald frame, has several row stop over bars on it more.Stop over bar is that inside and outside two kinds of conductors are separated and form the conjunction opening circuit by thick plastic film, and many warp stop sheets are enclosed within on stop over bar, and each root warp thread is all alone through a slice warp stop sheet.When loom running, warp tension, by warp stop sheet pull-up, makes it not contact with stop over bar inner wire, and circuit is off-state.In the time of cracked ends, warp stop sheet correspondingly falls by deadweight, contacts with inside and outside two conductors of stop over bar simultaneously, and circuit is connected, and sends stopping signal.
Warp stop motions is owing to being just to monitor warp break after warp break; therefore this device has certain delay, cannot shut down timely, and the loom of Modern High-Speed operation is very high to rate request; Delayed shutdown, the warp thread disorderly flying after fracture will affect the safety of loom operation.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of loom broken yarn acquisition equipment, this loom broken yarn acquisition equipment can be caught the warp thread of fracture in time.
The technical solution adopted for the present invention to solve the technical problems is:
This loom broken yarn acquisition equipment comprises capture platform, described capture platform is set in parallel in a side of warp thread transmission plane, on described warp thread, be provided with the compressing tablet inductor whether monitoring warp thread ruptures, every described warp thread all on described capture platform corresponding being provided with catch groove, described two ends of catching groove are respectively arranged with air nozzle and bleeding point, the jet direction of described air nozzle is consistent with the transmission direction of described warp thread, the jet amount of described air nozzle equals the rate of air sucked in required of described bleeding point, air nozzle described in described compressing tablet control.
As preferably, described in catch the groove edge of groove both sides be provided with soft of the activity of the described warp thread of clamping, the movable other end rotation in one end that described activity is soft is fixed on described air nozzle side.
As preferably, described in catch groove notch be trapezoidal, described air nozzle is arranged on the narrow end of notch, described bleeding point is arranged on slot opening end.
As preferably, described air nozzle and described bleeding point are by a channel connection with air pump.
The invention has the advantages that:
Utilize the air-flow of described air nozzle ejection that the pressure of warp thread one side is reduced, make the warp thread of fracture catch groove described in entering under the attraction of air-flow, utilize air-flow the friction of weft yarn to be kept to the tension force of warp thread simultaneously, prevent that warp thread from disorderly flying.
Accompanying drawing explanation
Fig. 1 is the structural representation of this loom broken yarn acquisition equipment.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
In the present embodiment, consult Fig. 1, this loom broken yarn acquisition equipment comprises capture platform 100, described capture platform 100 is set in parallel in warp thread 10 and transmits a side of plane, on described warp thread 10, be provided with the compressing tablet inductor 400 whether monitoring warp thread 10 ruptures, every described warp thread 10 all on described capture platform 100 corresponding being provided with catch groove 110, described two ends of catching groove 110 are respectively arranged with air nozzle 200 and bleeding point 300, the jet direction of described air nozzle 200 is consistent with the transmission direction of described warp thread 10, the jet amount of described air nozzle 200 equals the rate of air sucked in required of described bleeding point 300, air nozzle 200 described in described compressing tablet control.
Above-mentioned loom broken yarn acquisition equipment, the both sides on described groove edge of catching groove 110 are provided with soft 120 of the activity of the described warp thread 10 of clamping, the movable other end rotation in one end that described activity is soft 120 is fixed on described air nozzle 200 sides, because spraying air-flow velocity, air nozzle 200 comparatively fast cause described yarn 10 to reduce by force in the face of a side pressure of catching groove 110, described weft yarn 10 sprays at described air nozzle 200 described in entering under the attraction of air-flow catches groove 110, is clamped and is caught by soft 120 of described activity.
Above-mentioned loom broken yarn acquisition equipment, described notch of catching groove 110 is trapezoidal, described air nozzle 200 is arranged on the narrow end of notch, described bleeding point 300 is arranged on slot opening end, due to air nozzle 200 sprays air-flow can be because kinetic energy loss certain diffusion that occur, notch broadens gradually and can make the air-flow of diffusion catch groove 110 described in not overflowing.
Above-mentioned loom broken yarn acquisition equipment, described air nozzle 110 and described bleeding point 120, by a channel connection with air pump, keep the balance of air-flow in groove, and weaving air-flow overflows.
The working method of above-mentioned loom broken yarn acquisition equipment:
Described compressing tablet inductor 400 monitors after warp thread 10 broken strings, corresponding described air nozzle 200 is started working, the air-flow that utilizes described air nozzle 200 to spray reduces the pressure of warp thread 10 1 sides, make the warp thread 10 of fracture catch groove 110 described in entering under the attraction of air-flow, utilize by soft 120 of described activity simultaneously and clamp and catch, prevent that warp thread 10 from disorderly flying.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., all should be included in protection scope of the present invention.
