Abstract

The invention discloses a process for handling shutdown of a weaving machine due to weft breaking. The process includes the following steps: step 1, after the weaving machine completes beating-up action of Nth weft, entering a process of weft insertion of N+1th weft, and detecting whether weft abnormality appears or not in the process of weft insertion; step 2, if the defected weft is normal, continuing to weave until weft insertion of N+2th weft is detected, and if the detected weft is abnormal, positioning and stopping the weaving machine to a certain angle of the N+2th weft; step 3, automatically, slowly and forwards rotating to a set angle of N+3th weft, and being adjusted by a control system, correcting weft number to be the weft number of an N+1 section and enabling a warp letting-off mechanism and a reeling mechanism to stop at the N+1th weft; step 4, after manual processing of weft yarn is completed, restarting the weaving machine for work, and if weft demounting needs to be continued, pressing a reverse button, allowing the weaving machine to forwards rotate by one cycle, correcting the weft number to be the weft number of an N section, retreating the weft letting-off mechanism and the reeling mechanism by one weft. By the process, faults of a weft-broken shutdown portion can be reduced, and the weaving machine is low in maintenance cost.

Description

A kind of loom is processed the disconnected technique of shutting down of latitude

Technical field

The present invention relates to a kind of loom and process the disconnected technique of shutting down of latitude.

Background technology

Fabric is interwoven by warp thread and weft yarn.Latitude is disconnected shuts down while being the problems such as weft yarn appearance fracture, empty latitude or double weft, and loom stops mechanical movement.

Modern Rapier looms is in weaving process, and weft insertion system often draws a weft yarn, and levels warp thread moves up and down once, and reed just beats up once, so just forms sheet fabric.In wefting insertion process, for fear of there is the phenomenons such as staplings, empty latitude, double weft, spy arranges weft examining system, occurs weft yarn abnormal conditions, and shut down location in time, prevents that defective cloth phenomenon from appearring extremely weaving in weft yarn.Loom control system receives latitude and stops after signal, and brake application stoping, shuts down angle and generally surpass the beginning wefting insertion angle of the second latitude in time, and then loom stops angle to the latitude of the 3rd latitude at a slow speed.In order to complete the weft yarn work of processing, loom needs to latitude, to stop for auto-reverse two weeks the wefting insertion angle of the first latitude, handles after weft yarn the work of directly starting shooting.This process also claims backward weft seeking weaving process.

Due to this weft yarn processing procedure, need slow-speed weft finding clutch action accurately, control sensitively, parts are used the degree of reliability large, so higher to the requirement of slow-speed weft finding clutch, Costco Wholesale is higher.So stopping processing method, existing loom weft there is certain familiar lacunas.This scheme is had relatively high expectations to machinery and the supporting of electrical equipment control in addition, also high to the maintenance cost of loom.

Summary of the invention

Technical problem to be solved by this invention is just to provide a kind of loom and processes the disconnected technique of shutting down of latitude, and simplification latitude is disconnected shuts down action, and lower to the supporting requirement of loom machinery and electrical equipment control, and the maintenance cost of loom is low.

For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of loom is processed the disconnected technique of shutting down of latitude, comprises the steps:

Step 1, after loom completes N latitude beating-up, enters N+1 latitude wefting insertion process, and in wefting insertion process, weft examining system is carried out wefting insertion detection, detects whether occur that weft yarn is abnormal;

Step 2, if it is not abnormal to detect weft yarn, proceeds to weave, until N+2 latitude process detects.If detect weft yarn, occur that extremely, certain angle of N+2 latitude is shut down in location;

Step 3, is just forwarding at a slow speed N+3 latitude set angle automatically to, and under the adjustment of control system, latitude number is modified to N+1 section latitude number, and warp-feeding mechanism and spooler are parked in N+1 latitude

Step 4, after the complete weft yarn of artificial treatment, the loom work of again starting shooting, as need continue to tear open latitude, by invert button, loom forward 1 week, latitude number is modified to N section latitude number, and warp-feeding mechanism and spooler retreat 1 latitude

Described loom is processed the disconnected technique of shutting down of latitude and is applicable to the loom that electric power transmission volume configures.

The present invention's employing is just being sought latitude weaving process and is being processed the disconnected shutdown of latitude, and its beneficial effect is: 1, the disconnected shutdown action of loom weft is simple; 2, loom component structural is simplified; 3, the disconnected partial fault rate of shutting down of loom weft is few.

Accompanying drawing explanation

Below in conjunction with the drawings and specific embodiments, the invention will be further described:

Fig. 1 is that loom of the present invention is processed the disconnected flow chart of shutting down technique of latitude.

The specific embodiment

As shown in Figure 1, loom of the present invention is processed the disconnected technique of shutting down of latitude and is applicable to the loom that electric power transmission volume configures,

Specifically comprise the steps:

Step 2, if it is not abnormal to detect weft yarn, proceeds to weave, until N+2 latitude wefting insertion detects, abnormal if detection weft yarn occurs, certain angle of N+2 latitude is shut down in location;

Step 4, after the complete weft yarn of artificial treatment, the loom work of again starting shooting, as need continue to tear open latitude, by invert button, loom forward 1 week, latitude number is modified to N section latitude number, and warp-feeding mechanism and spooler retreat 1 latitude.

It is weft detector that above-mentioned loom is processed the disconnected weft examining system of shutting down in technique of latitude, in existing loom, generally adopts.In step 2, certain angle of N+2 latitude is shut down in location, and this angle is loom brake angle, is generally 120---140 degree, because be emergency brake, angle has error, after loom stops, surpasses and selects latitude to refer to operating angle.In step 3, automatically just forwarding at a slow speed N+3 latitude set angle to, this set angle is explained as follows, loom object be at a slow speed exactly under electrical apparatus control system is controlled vehicle positioning stop to specified angle, be generally the 30---45 degree of loom, convenient processing weft yarn and the wefting insertion of not driving are ready.

Claims

1. loom is processed the disconnected technique of shutting down of latitude, it is characterized in that comprising the steps:

Step 3, is just forwarding at a slow speed N+3 latitude set angle automatically to, and under the adjustment of control system, latitude number is modified to N+1 section latitude number, and warp-feeding mechanism and spooler are parked in N+1 latitude;

Step 4, after the complete weft yarn of artificial treatment, loom start work, as need continue to tear open latitude, by invert button, loom forward 1 week, latitude number is modified to N section latitude number, and warp-feeding mechanism and spooler retreat 1 latitude.

2. loom according to claim 1 is processed the disconnected technique of shutting down of latitude, it is characterized in that: described loom processing latitude breaks and shuts down the loom that technique is applicable to the configuration of electric power transmission volume.
