Abstract
A kind of automatic weft removing device, it is located near the weft yarn jet of loom, the mistake yarn that the folding latitude takes place can be taken out automatically, it is characterized in that, includes and dials yarn feeding device, gets yarn feeding device, air injection unit and control device; And when loom carries out producing in the weaving operation folding latitude mistake yarn, can start automatically by means of control device and dial yarn feeding device, push aside and will miss yarn, and cut-out weft yarn, to miss yarn and in fell, take out by getting yarn feeding device again, get rid of and will miss yarn, to reach the effect of automatic weft removing via air injection unit.
Description
The present invention relates to a kind of automatic weft removing device, particularly relate to a kind of jet loom that is used in the weaving operation, when detect weft yarn have the folding latitude situation the time, the automatic weft removing device that can automatically weft yarn be pushed aside, cut off and get rid of from fell.
Along with section hold flourishing day by day, progressively develop into the production operation of automation in the various production operations, and in the weaving operation, traditional weft yarn weaving mode is to utilize to have the shuttle machine to carry out the weaving operation, and because its weaving speed is slower, being replaced gradually by jet loom (being shuttle-free loom), and so-called jet loom is weft yarn to be carried out ahead of schedule by weft spindle extract out and keep in, and after the yarn instruction is put in each reception, emit quantitative weft length, the mode of utilize spraying again sprays into weft yarn in the warp thread of opening, and weft yarn is squeezed in the fell by reed, via shear the weft yarn that penetrates is cut off again, carrying out the injection of another weft yarn, and finish through, interweaving of weft yarn.But, jet loom is because its weaving speed is quite fast, therefore, in the weaving operation, cause the situation of weft yarn complications or broken yarn once in a while, in this case, when jet loom when carrying out the weaving operation, must there be the staff to examine the weaving situation looking on, and when the situation of tortuous weft yarn or broken yarn takes place, must wait for that the staff goes to processing, weft yarn is extracted out in warp thread, and cause the waste of cost of labor in the production operation and cause the waste of stand-by period, and present jet loom, when weft yarn had the situation of complications or broken yarn, its shear also was subjected to drive shaft and the operation of shearing, therefore every picking once, promptly carry out shearing manipulation one time, therefore, when producing the situation of mistake yarn, the mistake yarn also is sheared device and cuts off, to cause the staff to take out the inconvenience of weft yarn, and bring the inconvenience of production operation and reduced weaving efficient, make jet loom more undesirable in the use.
Main purpose of the present invention is providing a kind of automatic weft removing device, and it has the weft yarn of automatic eliminating complications, and the effect that turns round again automatically, with the purpose that reaches automated production and enhance productivity.
In order to achieve the above object, automatic weft removing device of the present invention, it is located near the loom weft yarn jet hole, the mistake yarn can be taken out automatically, and it includes and dials yarn feeding device, gets yarn feeding device, air injection unit and control device.When loom carries out in the weaving operation producing the situation of mistake yarn, can start automatically by means of control device and dial yarn feeding device, transfer to and will miss yarn, will miss yarn and in warp thread, take out by means of getting yarn feeding device again, to reach the effect of automatic weft removing.
Dialling yarn feeding device is to drive by means of first drive unit to collude the rotation of yarn device, ticks on warp thread and will miss yarn.Get yarn feeding device and be provided with driving wheel, follower, second drive unit, the 3rd drive unit and cutter unit, driving wheel is provided in a side of near the appropriate location of colluding the yarn device, can drive by means of second drive unit and rotate, follower is provided in a side of on the 3rd drive unit, can drive by means of the 3rd drive unit, and move, and be in contact with one another with driving wheel toward the driving wheel direction.Cutter unit then is located at the spray yarn mouth position of braiding machine, makes when colluding the yarn device and will miss yarn and tick, can the mistake cotton yarn tape between driving wheel and follower, strain and will miss yarn, will miss the yarn cut-out by means of cutter unit; And via getting yarn feeding device the mistake cotton yarn tape of complications in warp thread gone out, the mistake yarn that utilizes air injection unit to cut off again blows away.Control module can be controlled the start of dialling yarn feeding device, getting yarn feeding device and air jet system automatically.
Therefore, when weft yarn weaves and sprays the situation of wrong yarn, can controlled unit controls, weaving operation is quit work, and control group first drive unit of system group yarn feeding device automatically and rotate, drive is colluded the yarn device and is rotated, and the mistake yarn is drawn out between the driving wheel and follower of getting yarn feeding device, second drive unit starts then, make follower move contact, and will miss the yarn tension, and will miss yarn by means of cutter unit and cut off toward the driving wheel direction, move via the revolution of driving wheel again, to miss yarn and take out, the mistake yarn that will be cut off by air injection unit simultaneously blows away, to finish the operation of automatic weft removing, then, dial yarn feeding device and get yarn feeding device with the reverse reverting previous status.
