Description
Technical field
The utility model is a kind of automatic stop arrangement, the disconnected automatic stop arrangement of particularly a kind of water jet looms weft yarn spray.
Background technology
Along with the development of textile industry, more and more enterprises is with the innovation kind of many warps, many latitudes, the thin dawn number emphasis as its production.And thin dawn number and powerful relatively poor weft yarn stage casing disconnection phenomenon can occur and inweave fell at random in the weft yarn flight course, form fabric defect, and we are referred to as this fault " spray is disconnected ".The quality of lining appears badly influencing in " spray is disconnected ".
Summary of the invention
The utility model technical problem to be solved is, has no progeny spray occurring, can detect " spray at once
Disconnected " phenomenon, and make board out of service automatically, inform operating personnel through indicator lamp simultaneously.Invented the disconnected automatic stop arrangement of water jet looms weft yarn spray for this reason.
The utility model is realized as follows: said water jet looms weft yarn spray is certainly disconnected
Stop device, by mu balanced circuit W, diode D1, D2, D3; Triode T, three grades of IGCT M, resistance R 1, R2, R3, R4 and capacitor C 1, C2 and indicator lamp L form; The negative pole of W is connected with power supply with anodal, and C1 is connected in parallel between the S utmost point and negative pole of W, is connected in parallel between the S utmost point and negative pole of W after R1 and the C2 series connection; The S utmost point is connected with the colelctor electrode of triode T through R2, and the emitter stage of T is connected with the negative pole of W; The base stage of T is connected with the series connection point of R1 and C2, and the colelctor electrode of T is connected with the emitter stage of T through R4; The colelctor electrode of T is connected with the control utmost point of M, and the positive pole of M is connected with indicator lamp L, and L is connected with the S utmost point of W through R3; The negative pole of M is connected with the negative pole of W; The series connection point of R1 and C2 is connected with the positive pole of D1, and the negative pole of D1 is connected with the negative pole of D2, and the positive pole of D2 is connected with relay J, and J is connected with the positive pole of D3, and the negative pole of D3 is connected with the positive pole of M; The negative pole of D1 is connected with the moving contact K of contact switch, and the static contact B of contact switch is connected with the negative pole of W.
The model of said mu balanced circuit W is L7812CV.
The model of said triode T is 9014C.
The model of said three grades of IGCT M is MCR100-8.
The good effect of the utility model is following: the effect of the utility model is an autostop when " spray is disconnected " occurring at machine, so effectively avoided the appearance of " spray is disconnected ", has improved the quality of lining greatly.
Description of drawings
Fig. 1 is the utility model circuit structure diagram
The specific embodiment
As shown in Figure 1, the disconnected automatic stop arrangement of said water jet looms weft yarn spray is by mu balanced circuit W; Diode D1, D2, D3, triode T, three grades of IGCT M; Resistance R 1, R2, R3, R4 and capacitor C 1, C2 and indicator lamp L form, and the negative pole of W is connected with power supply with anodal, and C1 is connected in parallel between the S utmost point and negative pole of W; Be connected in parallel between the S utmost point and negative pole of W after R1 and the C2 series connection, the S utmost point is connected with the colelctor electrode of triode T through R2, and the emitter stage of T is connected with the negative pole of W; The base stage of T is connected with the series connection point of R1 and C2, and the colelctor electrode of T is connected with the emitter stage of T through R4; The colelctor electrode of T is connected with the control utmost point of M, and the positive pole of M is connected with indicator lamp L, and L is connected with the S utmost point of W through R3; The negative pole of M is connected with the negative pole of W; The series connection point of R1 and C2 is connected with the positive pole of D1, and the negative pole of D1 is connected with the negative pole of D2, and the positive pole of D2 is connected with relay J, and J is connected with the positive pole of D3, and the negative pole of D3 is connected with the positive pole of M; The negative pole of D1 is connected with the moving contact K of contact switch, and the static contact B of contact switch is connected with the negative pole of W.
The model of said mu balanced circuit W is L7812CV.
The model of said triode T is 9014C.
The model of said three grades of IGCT M is MCR100-8.
The operation principle of the utility model is following: in the board normal operation process, indicator lamp L is an off-state; When the compressing that receives spray staplings yarn as moving contact K touches static contact B, the instantaneous conducting of diode D2, the relay disconnecting circuit makes board shut down; Simultaneously, the instantaneous conducting of diode D1, the base stage of triode T produces low level, and triode ends; Three grades of IGCT M conducting this moment, indicator light circuit is formed the loop, and indicator lamp is bright, and operating personnel obtain the disconnected prompting of board weft yarn spray; Spraying disconnected the processing immediately, spray is disconnected finish dealing with after, click relay, diode D3 conducting; Indicator light circuit breaks off, and entire circuit restPoses, and board recovers the road normal operation.
