The furnishing method of warp knitting machine and device and the cotton collection of yarn carrying method and detection transport and wind that continues send dust collecting method and dust-catching and delivering bucket

The furnishing method and device, the carrying method of broken yarn and the collection of detection transport and wind cotton that the present invention relates to warp knitting machine send dust collecting method and dust-catching and delivering bucket, and the present invention is specially adapted to have the warp knitting machine of 2 row needle-bars.

In the warp knitting machine, particularly in warp knitting machine with front and back 2 row pins, the base fabric that is formed with the yarn guiding chase comb yarn feeding by each base fabric forms yarn by base fabric before and after the braiding of front and back pin row, simultaneously, form with the connection yarn between the sley bar and alternatively be woven in two base fabrics by being located at base fabric with the connection yarn of sley bar yarn feeding, connect two base fabrics by linking yarn, that is to say that the formation method of two-plane type warp knitted fabric is fully known.

This two-plane type warp knitted fabric is cut the connection yarn along weaving direction, make two pieces of tricots, as required, the connection yarn on the base fabric surface of cutting is imposed processing such as wrinkling, napping and clippingization is made woollen blanket or vehicle seat fabric.

But, the common circumvolution of braiding warp in this type of warp knitting machine is being called as on the bobbin of axle, and be bearing on the warp knitting machine, or draw by the dress creel that disposes the warp bag, above-mentioned dress creel is also referred to as bobbin cradle, promptly be arranged on the warp knitting machine by above-mentioned any method, each yarn is planar to the braiding portion yarn feeding that is provided with knitting needle by dividing sinker parts such as spreader or keevils.

As mentioned above, particularly the warp knitting machine of classifying the several column form as with knitting needle is knitted when compiling woollen blanket, and as the warp (yarn) of pile loop line, promptly the pile loop line uses short fiber yarns such as Dralon, pure wool, cotton textiles with connecting line.This connecting line is generally drawn from frame by the conveying roller on the warp knitting machine, to the guide means yarn feeding that is called yarn guiding chase comb.When continuing yarn, detect relaxing and shutting down of yarn by the menopause tablet device that detects broken yarn.

That is, this pile loop line is guided the connecting line of braiding portion with before the yarn guiding chase comb with connecting line, for example, adopts yarn road as shown in Figure 6 in the past.

Among Fig. 6, the 10th, by the pile loop that constitutes as short fiber yarns such as cotton yarns connecting line, 11,12nd, conveying roller, the 13rd, the menopause tablet that works during broken yarn, it is arranged between the pipe 14,15, has constituted the menopause tablet device that detects the yarn that continues.The 20th, tensioning apparatus, the 21st, spreader, pile loop line by menopause tablet passes through spreader 21 with connecting line by tensioning apparatus 20, the thread guide eyelet that passes the guide piece 19 that is installed on the yarn guiding chase comb 17 is to braiding portion (comprising knitting needle) 16 yarn feedings, in the warp knitting machine in the past, general yarn road constitutes as mentioned above.

As everyone knows, when weaving, or during the yarn qualities difference, very easily producing the wind cotton between the thread guide eyelet 19a near the conveying roller 11,12 by staple fibre, by kink mutually between the yarn, further aggravation wind is cotton produces for friction etc., the wind cotton of dispersing sticks in the middle of the yarn road.

The result, in the yarn road before arriving thread guide eyelet 19, though the pile loop line leaf gauge of connecting line 10 by warp knitting machine, but the wind cotton is the drag hook shape, interacts between batting, passes the yarn road together, when tension force hour, cause the mutual interlacing of yarn, this state lasts till final by till the thread guide eyelet 19a always, becomes a reason that produces broken yarn.

In addition, in this type of braiding machine in the past, seldom have in warp knitting machine, to be provided with and collect the such technological thought of the cotton bucket of wind.The wind cotton that produces with the braiding tricot is given free rein to fully and disperses, and at most also just with air cannon it is blown afloat, and makes it to disperse, and carries out the cotton collection of ground wind.

In addition, on a part of warp knitting machine, make the cotton bucket-shaped device of piling up of wind though have, also just collect the wind cotton for the moment with simple box-type device, in time the wind cotton is swept, good working definitely is far from being.

The present invention is intended to solve the cause of wind cotton, and yarn feeding smoothly when realizing this type of warp knitting machine braiding makes the braiding process smooth and easy, improves braid efficiency.

Promptly, the purpose of first invention of the present invention is: for eliminating the shortcoming of above-mentioned prior art, on warp knitting machine, from the yarn feeding position of warp knitting machine to the yarn road of knitting position, utilization can make warp thread do not interfere with each other, smoothly to the isolating means such as body of knitting needle guide, a kind of furnishing method and device thereof are provided.

The purpose of second invention of the present invention is: utilize isolating means such as body as above-mentioned yarn feeding position from warp knitting machine to the warp knitting machine in the yarn road of knitting position, provide a kind of when broken yarn, the yarn end that continues in the retraction isolating means successfully can be transported to the method in exits such as body, and provide a kind of and when finding broken yarn, can stop the warp knitting machine running, and make and cut off the yarn tensioning, in isolating means, carry broken yarn to detect transport automatically the broken yarn end is directed to the outlet of isolating means.

Also have, the 3rd purpose of the present invention is: solve for collecting the problems referred to above that exist when wind is cotton to use collection bucket, provide the collection of the high efficiency carrying wind of a kind of energy cotton, control of dust to send dust collecting method, and the dust-catching and delivering bucket that for this reason constitutes.

For reaching the 1st purpose of the present invention, the warp knitting machine furnishing method that the present invention relates to is: many warp thread with planar in the warp knitting machine of braided fabric yarn feeding, make by isolating means to be mutual contactless state from braiding machine yarn feeding position to each yarn the yarn guiding port of sley bar and to carry out yarn feeding.Reach the 1st purpose of the present invention thus.Said herein yarn feeding position is meant when having conveying roller, broken yarn detection means on the biserial pin warp knitting machine, and yarn has passed through the position of conveying roller, broken yarn detection means.

According to above-mentioned furnishing method, warp thread does not interfere with each other to not producing between the yarn guiding port in the yarn feeding position.

Though above-mentioned isolating means has the whole bag of tricks, it is very effective to use elastic tube to make isolating means.That is, when adopting elastic tube as isolating means, the yarn guiding chase comb that comprises yarn guiding port can to the pin row rock type in compiling, can be with braiding motion braiding successfully.

Yarn feeding device of the present invention can corresponding warp thread radical constitute the isolation yarn guiding body that is made of elastic tube etc. as the yarn road.Elastic tube one end ties up on the keevil of being located at the yarn feeding position, and the other end ties up on the rigid pipe of the yarn guiding port that comprises yarn guiding chase comb.Therefore, can easily implement above-mentioned furnishing method.

Above-mentioned yarn guiding port can be sley bar or fixing in its vicinity rigid pipe, also can simply the rigid pipe as yarn guiding port be fixed on the yarn guiding chase comb as thread-carrier to constitute.

Can be the rigid pipe spaced apart in the yarn guiding chase comb front and back, this is that pile loop line in the past divides 2 to be listed as setting with yarn guiding chase comb, the situation that yarn is separated, led to yarn by these yarn guiding chase combs, but also can obtain effect same with 1 row arrangement.
