Abstract
The invention discloses an optical yarn breakage indicating device which comprises a hollow cylinder. Two ends of the hollow cylinder are closed via a first end cap and a second end cap, yarns are transferred in the hollow cylinder along the axial direction of the same, small holes allowing the yarn to pass through are formed in each of the first end cap and the second end cap, a light-emitting ring is arranged around each small hole of the first end cap or the second end cap, the light-emitting rings emit parallel light surrounding the corresponding yarns, and a light guide fiber is further arranged in the hollow cylinder axially and is electrically connected with a yarn guide alarm. The yarns after broken are irradiated by the parallel light emitted by the light-emitting rings, the parallel light after irradiating to the yarn generates diffuse reflections which are polymerized onto the light guide fiber through a reflecting coating, the yarn guide alarm gives out an alarm, and the entire device adopting a light monitoring mode is simple in structure, simplified in circuit and capable of preventing generation of static electricity.
Description
Affiliated technical field
The present invention relates to loom monitoring apparatus field, especially, is a kind of optics yarn breakage indicating device for 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.
Whether rupture owing to adopting the mode of traditional energising induction to monitor warp thread, therefore below every warp thread, all need corresponding circuit to coordinate, the wiring of whole loom is quite complicated, increase operating cost, meanwhile, large-scale cloth circuits, when affecting the stability of monitoring system, also can cause the increase of warp thread static content, be unfavorable for the safety in production of textile enterprise.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of optics yarn breakage indicating device, fast monitored yarn breakage when this optics yarn breakage indicating device compact conformation.
The technical solution adopted for the present invention to solve the technical problems is:
This optics yarn breakage indicating device comprises hollow cylinder, described hollow cylinder two ends are sealed by the first end cap and the second end cap, yarn in described hollow cylinder along the axial transmission of described hollow cylinder, on described the first end cap and the second end cap, have the aperture passing for described yarn, the aperture of described the first end cap or the second end cap is provided with Luminous Ring around, described Luminous Ring is sent the directional light around corresponding yarn, in described hollow cylinder, be also axially provided with optical fiber, described optical fiber and the electrical connection of guide alarm.
As preferably, described Luminous Ring is formed by same source of parallel light selective masking.
As preferably, described yarn is distributed on described hollow cylinder axis around, and the inwall of described hollow cylinder is coated with reflecting coating, and described optical fiber is arranged on the axis of described hollow cylinder.
As preferably, described the first end cap or the second end cap inner side that Luminous Ring is not set are provided with reflector layer.
The invention has the advantages that:
The directional light being sent by described Luminous Ring after yarn breakage irradiates, directional light exposes to the diffuse reflection producing after yarn, diffuse reflection is polymerized on described optical fiber by described reflecting coating, described guide alarm gives the alarm, whole device adopts the monitoring mode of light, simple in structure, simplify circuit, prevent the generation of static simultaneously.
