Abstract
The invention provides a broken warp indication device of a weaving machine. The broken warp indication device comprises an optics emitter, an optics receiver and an alarm module which is electrically connected with the optics receiver. The optics emitter and the optics receiver are arranged on the upper portion and the lower portion of the same side of a warp conveying plane respectively, the emitting direction and the receiving direction are parallel to the warp conveying plane, reflecting transparent films are arranged above and below the warp, and the same angle and the same position are formed through the reflecting transparent films on the same side. The light rays emitted by the optics emitter are reflected by the reflecting transparent films on one side to pass through the warp, and the reflecting transparent films on the other side reflect the light rays blocked by the warp to the optics receiver. The principle that the reflecting transparent films can carry out reflection and transmission at the same time is adopted, the light rays of the optics emitter are divided into a plurality of detected light rays, the detected light rays are transmitted to the optics receiver through the same reflection and transmission principle, and the whole structure is simple and reliable.
Description
Affiliated technical field
The present invention relates to field of textile machinery, especially, is a kind of cracked ends indicating device 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, minute comb is rotary.Adopt stop over postures 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.During 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.When 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.
No matter make photo-electric type also, stop over posture still divides comb formula all to exist induction mechanism to increase along with the increase of warp number, this simple dependence mode that independently whether induction mechanism induction warp ruptures can cause whole apparatus structure complicated, the consequence that reliability is not high.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of loom cracked ends indicating device, this loom cracked ends indicating device is simple in structure, and monitors reliably the operation of warp.
The technical solution adopted for the present invention to solve the technical problems is:
This loom cracked ends indicating device comprises optical launcher, the alarm module of optical receiver and the electrical connection of described optical receiver, described optical launcher and described optical receiver respectively homonymy are arranged on the upper and lower of warp thread transport plane and transmit and receive direction and be parallel to described warp thread transport plane, the upper and lower of every warp thread is provided with reflective hyaline membrane described in reflective hyaline membrane and homonymy and is identical angle and position, the light of described optical launcher transmitting is the described warp thread of light process after the described reflective hyaline membrane reflection of a side, the light reflection that the described reflective hyaline membrane of opposite side blocks warp thread is to described optical receiver.
As preferably, the light of described optical launcher transmitting is visible ray.
As preferably, two described reflective hyaline membranes away from described optical launcher, optical receiver are provided with light reflection coating.
As preferably, described warp is positioned at a side of described optical receiver side, and parallel described warp transport plane is provided with the transparent indication panel with diffuse reflection coating.
The invention has the advantages that:
Utilize described reflective hyaline membrane can reflect the principle with transmission simultaneously, the light that the light of described optical launcher is divided into Multi-channel detection, the principle of utilizing same reflection and transmission to described optical receiver, makes total simple and reliable the light transmission detecting.
