Description

[0001] The present invention relates to a large diameter low density yarn weaving device,

The present invention relates to a large-diameter low-density yarn weaving machine including a koi yarn, and more particularly, a large-diameter low-density yarn having a diameter of 18 mm or more including a koi yarn is maintained at a high tension rate, Density loom weaving machine comprising a Koi yarn which is weaved in a tensioned state and whose stomata and warp tissues are firmly fixed by the restoring force of the yarn itself after weaving.

Natural fibers such as koi or jute are natural friendly and biodegradable natural materials that cause almost no chemical reaction with the soil, so there is no soil pollution and durability, which can prevent the loss of the soil, and the low density of the yarn structure, It is widely used for the purpose of preventing use of a road surface cover for preventing dust and muddy water from scattering and for preventing loss of seeds in various vegetation mats or vegetation spaces of slopes.

However, in order to use it as a cover or a mat, it is necessary to secure a certain degree of thickness (about 40 mm). Therefore, a large-diameter yarn is used. In this case, since the thickness is as thick as a rope, There is a problem that the loom breaks down or malfunctions during the weaving process. Therefore, there is a growing need for a weaving apparatus capable of improving the weaving apparatus.

Thus, in the prior art, a plurality of tilted slopes supplied from a tilted supply reel are alternately lifted and lowered, respectively, and are wound on a twill winding reel through a pair of the ina frame, A pair of weaves that feed weft yarns between crossed slopes are passed and lattice type weaving is performed so that the weaving machine manually operated by a pair of pedals (manual operating portion) I am suggesting.

However, in the conventional weaving machine including the above-mentioned prior art, since the density of the woven fabric is not formed densely due to the characteristics of the yarn made of the low-density large-diameter yarn, deformation or bending of the fabric tissue is easily caused by the external load being pushed, There is a problem that pores are formed on the surface of the tissue, which leads to loss of soil and seeds.

Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a large diameter low-density yarn having a diameter of 18 mm or more including a Koi yarn in a state of being stretched at a high density, And a Koi yarn yarn in which the stiff tissue is firmly fixed by the restoring force of the yarn after the weaving operation.

In order to achieve this object, a feature of the present invention is that a warp yarn W1 and a weft yarn W2 are formed by a low density Koi yarn having a diameter of 18 to 26 mm and the warp yarn W1 is wound around the first and second heights H The weft W2 is configured to be pressed by the body B to form the mat tissue M after the weft W2 has passed through the closing opening O. When the weft W2 passes through the closing opening O, A take-up roller unit 10 which is composed of a pair of upper and lower rollers and is arranged to control the slope W1 pull-in speed; And a discharge roller unit 20 connected to the drawing roller unit 10 and adapted to control a discharge speed of the mat tissue M behind the heald H. [

At this time, the discharge roller unit 20 is driven at a speed of 1 to 50% faster than the drawing roller unit 10 so that the mat tissue M is formed between the drawing roller unit 10 and the discharge roller unit 20 And the warp W1 is provided so as to exert a tensile force in the pull-out direction.

The drawing roller unit 10 and the discharge roller unit 20 are driven at a point of time when the first and second healds H1 intersect with each other to intermittently feed the tilt, The first and second light beams H are moved to the upper and lower dead points in a state where the drawing roller unit 10 and the discharge roller unit 20 are stopped and a second tension force is generated by pulling the tapers in the upward and downward directions .

The warp yarn W1 is received in a yarn roll mounting portion 30 and the yarn roll mounting portion 30 is provided with a transverse bar 31 extending in the transverse direction to sandwich a plurality of yarn rolls R, And a cradle (33) supporting the transverse bar (31) and separating the yarn rolls (R) to form an independent cradle space.

The discharge roller portion 20 is provided with a driving roller 20a for drawing the matte M and a pressure roller 20b for urging the matte M to elastically support the matte M so as to be in close contact with the driving roller 20a .

According to the present invention, a tension is formed so that a large-diameter low-density inclination that is fed into a loom due to a difference in rotation speed between a drawing roller portion and a discharge roller portion is pulled tight, the diameter is reduced, When the weft is crossed with the weft, the pulled-up tilted structure is restored, tightly fixed to the weft, and a dense and firm structure is formed, thereby providing a mat structure excellent in deformation prevention effect and durability.

2 is a schematic view showing a fabric structure woven by a large-diameter low-density yarn weaving apparatus according to the present invention.
3 is a schematic view showing an operation state of a large-diameter low-density yarn weaving machine according to the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention is based on the idea that a large tensile strength yarn with a diameter of 18 mm or more including a Koi yarn is provided with a high tensile strength and is weaved in a state of being stretched at a high density of a small diameter so that the stiffness and stiffness of the yarn are firmly fixed by the self- And includes a drawing roller portion 10 and a discharge roller portion 20 having different rotational speeds.

Natural matt weaving natural mats including straw, jute and coir are applied to the roads where there is a great concern about loosening of soil, including hiking trails, unpaved roads and slopes, and where there is a lot of pedestrian traffic. Natural yarn (in the present application, coir yarn) is used as a large diameter of 18 mm or more in order to weave at a thickness of 40 mm or more in a single plain weave. At this time, due to irregular fibers, . Therefore, the present invention solves the problem that the tissue is widened or deformed by the repulsive force exerted at the upper part after the weave of the mat is firmly fixed by reflecting the low density characteristic of the large diameter of Koiwon Company.

The low density coir yarns having a diameter of 18 to 26 mm forming a mat texture are woven through plain weaving wherein the warp yarns and the weft yarns are alternately crossed. Fig. 1 shows such a large diameter low density yarn weaving device. The warp yarns W1 wound on the portion R are alternately supplied to the first and second healds H which are cylindrically coupled and act in directions opposite to each other, A shuttle (weft insertion mechanism) to which one yarn or more yarn (Koi assigner) is connected is inserted from one side or both sides of the closing opening O and is wound into the weft opening (O) W2).

The inserted weft yarn W2 is pushed by the body B which is reciprocally transported by a pressing means such as a cylinder and is tightly brought into close contact with the intersection of the warp yarns W1 and then the above- By the return operation, the closing opening O through which the weft yarn W2 has passed is closed, and the mat fabric M is woven.

At this time, the drawing roller unit 10 is constituted by a pair of upper and lower rollers in front of the heald H and controls the drawing speed W1 to be fed to the heald H side. The drawing roller unit 10 is for feeding a plurality of strands of warp yarn W1 drawn out from the yarn roll fixing unit R into the loom at a constant speed and is provided with at least one of the warp yarns W1 The driving roller 10a is connected to the driving roller 10a for supplying the driving roller 10a and the driving roller 10a for supplying the driving roller 10a to the driving roller 10a. And functions as a pressure roller 10b to prevent the slope W1 from slipping during the supply process.

The warp yarn W1 is mounted on a yarn roll mounting portion 30 provided on one side of the drawing roller portion 10 and the yarn roll mounting portion 30 is extended in the lateral direction to form a plurality of yarn rolls R And a cradle 33 for supporting the transverse bar 31 and separating the yarn roll R from each other to form an independent mounting space.

At this time, the transverse bar 31 can feed a plurality of yarn rolls R using a single transverse bar 31 by sandwiching the plurality of yarn rolls R. In addition, It is possible to improve space utilization by arranging a plurality of transverse bars 31 as shown in the figure and to arrange more yarn rolls R in a limited space to supply more yarn slopes at a time, It becomes possible to provide a mat fabric (M).

As the discharge rollers 10 are rotated in the same direction in the process of inserting the yarn rolls R in the transverse direction to supply the warp yarns W1, warping of the warp yarns W1 is prevented, Is made of a hard material with a low density, so that it is possible to supply a large-diameter low-density yarn which is liable to cause damage or durability deterioration in a distorted state without deformation.

The discharge roller unit 20 is provided behind the heald H to control the discharging speed of the woven mat fabric M and is provided with driving means separately operated from the drawing roller unit 10. [ Accordingly, the supply of the yarn and the discharge of the woven mat tissue are simultaneously transferred at both ends of the loom, so that the feeding speed of the warp W1 and the discharging speed of the woven mat tissue M are maintained at the set speed ratio, Excessive deformation or deflection of the tissue is prevented from occurring in the discharge process, and rapid operation is performed.

That is, the discharge roller unit 20 is driven at a rate of 1 to 50% faster than the drawing roller unit 10 so that the mat tissue M is formed between the drawing roller unit 10 and the discharge roller unit 20 The warp W1 is pulled in the pulling direction.

When the rotation speed of the entry roller unit 10 and the rotation speed of the discharge roller unit 20 are different from each other, the slope W1, which is supported by the entrance roller unit 10, is relatively rotated at a relatively high speed Is pulled by the discharge roller portion 20, and the warp W1 thus stretched is reduced in diameter and passes through the heald H in a state where the tissue density is densely deformed.

That is, at the time when the weft is crossed with the weft yarn W2, the diameter of the warp yarn W1 is minimized so that the weft yarn W2 and the warp yarn W1 can closely contact with each other. As shown in Fig. 2, a gravitational force is exerted between the weft yarn W2 and the warp yarn W1 so that the tissue density becomes more dense, and a deformation including the warping or widening of the yarn during use .

The rotation speed of the discharge roller unit 20 which is operated at a high speed with respect to the speed of the entry roller unit 10 can be freely selected in consideration of the tension and density of the yarn. The discharge roller unit 20, however, ), It is difficult to expect a firm fixing force of the matting structure because the difference between the feeding speed and the discharging speed is not so large. When the speed is increased by more than 50%, the yarn is cut off due to excessive tensile force, It is preferable that the discharge roller portion 20 is driven at a speed of 1 to 50% faster than the drawing roller portion 10, because it leads to permanent damage.

The weaving apparatus according to the present invention is characterized in that the drawing roller unit 10 and the discharge roller unit 20 are driven at a point of time when the first and second helix eyes H1 intersect with each other to form a warp W1, The first and second light beams H move to the upper and lower dead points in a state where the drawing roller portion 10 and the discharge roller portion 20 are stopped and the warp W1 is moved It is possible to provide a structure in which the tensile strain for improving the warp yarns W1 and the weft yarn W2 can be more effectively obtained by causing the secondary pulling force to be pulled upward and downward.

3 (a), the drawing roller portion 10 for supplying the warp yarn W1 and the discharge roller portion 20 for discharging the woven fabric structure are wound in the warping state of the warp yarn W1 H) of the first and second helix H are intersected with each other so that the interference between the heald H and the yarn is minimized so as to prevent breakage or surface damage caused by contact .

As the operation of each roller portion is limited to the intersecting point of the helix H, the tensile force due to the difference in the rotational speed is not continuously applied to the warp W1 but is limited to the moment when the heald H is raised and lowered and the weaving is performed The excessive damage or deformation of the warp W1 is minimized.

On the other hand, the warp W1, which is primarily tensioned by the above-described operation of the both-side roller portions, is guided by the first and second light beams H, which move to the top dead center and the bottom dead center, A secondary tensile force is applied in the process of being pulled up and down. The inclined yarn W1 pulled in the inclined conveying direction and pulled in the first inclination direction is pulled up and down again by the upward / downward movement of the heald H, so that the both side roller portions can be operated with low output power. An effect of pulling the warp yarn W1 across the roller portion of the weft yarn W2 by pulling up and down the heald H and tensing up to the portion contacting with the roller is generated so that the density of the mat fabric M, So that it can be provided in a more solid and compact state.

The discharge roller unit 20 comprises a driving roller 20a for drawing the matte M and a pressing roller 20b for pressing the matte M and bringing the matte M into close contact with the driving roller 20a, The driving roller 20a is elastically supported and controls the tension of the mat tissue M.

If the pressure roller 20b is elastically supported so as to adhere the matte structure M to the driving roller 20a provided in the discharge roller portion 20, The yarn is pulled up to the yarn tension M of the yarn 10 by the warp yarn W1. However, when the excessive pulling force is applied, the yarn slips between the pressing rollers 20b to prevent damage to the yarn.
