The " method and apparatus for processing brassiere yarn " is a method of spirally twisting a covering yarn on the outer surface of a yarn drawn out from cheese and twisting the yarn and then brushed the yarn so that the twisted yarn is contacted within the ring-

However, when the above-described method is used to manufacture a microstructure, the thread is directly contacted with the inside of the magnet to form the baffle. Therefore, the baffle is not securely formed as a whole, This is a high problem.

Therefore, when the knitted fabric is knitted because the quality of the bristle yarn is not uniform, the defective ratio is increased and the product of good quality can not be produced, and the manufacturing cost is increased.

As another example, Korean Patent No. 10-1654913 discloses " a device for manufacturing a semiconductor device and a manufacturing method thereof ".

The above-mentioned " primer manufacturing apparatus and manufacturing method " is a method in which the first twist yarn and the second twist yarn are twisted while rotating in the opposite direction when they are twisted again, In a way that will cause it to happen.

However, the above-mentioned " machine manufacturing apparatus and manufacturing method " also has a disadvantage in terms of productivity due to the complicated structure of the apparatus and a difficult work process, and the defective rate is high, resulting in poor product quality.

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

FIG. 1 and FIG. 2 are a front view and a side view showing a machine for machining a pattern according to an embodiment of the present invention.

As shown in FIGS. 1 and 2, the apparatus for fabricating a warp yarn is provided with a yarn 100 loosened from a yarn supply roll 10 by passing through a bristle machining mechanism 12 to which a grinding stone 11 belongs, A baffle is formed, and then a baffle 200 having a baffle is wound around the base winding roll 13.

To this end, a yarn supply roll 10 on which a yarn is wound is disposed at a lower portion, and a yarn winding roll 13 which can wind a yarn is disposed at an upper portion. Thus, a yarn and a bristle yarn are wound on a path . ≪ / RTI >

At this time, the yarn and the bristle yarn can be advanced by receiving a force to pull the yarn from the yarn take-up roll 13 side, a pulling force from the intermediate sub-tension unit 25 to be described later, and the like.

A bristle machining mechanism 12 is provided on the yarn advancing path between the yarn supplying roll 10 and the warp yarn winding roll 13 to substantially form a blob on the surface of the yarn. (12) will be described later in detail.

Various means for guiding the smooth progress of the yarn and the bristle yarn are arranged on the yarn and the yarn traveling path.

For example, a yarn tension adjusting device 24 is provided at an upper portion of the yarn supplying roll 10, and a yarn unwound from the yarn supplying roll 10 advances through a yarn tension adjusting device 24, State can be maintained.

The yarn tension adjusting device 24 will be described later in detail.

A driving guide roll 26 is disposed below one side of the yarn tension adjusting device 24 and a yarn extending downward from the yarn tension adjusting device 24 is wound on the driving guide roll 26, The direction can be switched and extended upward.

A bristle machining mechanism 12 is provided above the drive guide roll 26. The bristle machining mechanism 12 at this time allows the yarn extending from the drive guide roll 26 to enter from below .

In addition, a sub-tension portion 25 having a triangular arrangement structure of two lower driving tension rolls 25a and one upper friction tension roll 25b is installed on the bristle machining mechanism 12 do.

Here, the friction tension roll 25b is formed of urethane or rubber material so as to be placed on the upper side between two lower driving tension rolls 25a, and the friction tension roll 25b Can be naturally rotated by friction with the driving tension roll 25a when the driving tension roll 25a is rotated.

That is, when the two lower driving tension rolls 25a are rotated in the counterclockwise direction, the upper friction tension roll 25b in contact therewith rotates clockwise.

The freely rotating friction tension roll 25b can be kept in contact with the driving tension roll 25a without being deviated left and right by the stopper bar 27 on both sides.

As a result, the bristles extending upward in a state in which the bobbles are formed through the bristle-forming mechanism 12 on the lower side are immediately passed through between the driving tension roll 25a and the friction tension roll 25b, It is possible to extend upward after passing between the tension roll 25a and the friction tension roll 25b, and the bristle yarn extending in this way is sandwiched between the driving tension roll 25a and the friction tension roll 25b So that it can be advanced to the upper side of the upper side winding roll 13 while maintaining a proper tension.

Further, on the upper portion of the sub-tension part 25, a priming winding roll 13 is provided as a means for winding a primer having been subjected to the bopple processing.

The base yarn take-up roll 13 can be rotated together with the take-up roll driving roll 28 disposed in parallel to this to wind the simulacrum.

At this time, at the position where the bristles enter the front end of the radial winding roll 13, that is, the radial winding roll 13 side, A ring-moving shaft 30 reciprocating horizontally along the longitudinal direction of the winding roll 13 is disposed.

In this state, the bristle yarn extending from the bottom extends over the ring 29 on the ring-moving shaft 30 and then proceeds to the side of the take-up windup roll 13. When the bristle yarn is wound around the base take- The ring moving shaft 30 and the ring 29 reciprocate right and left, so that the bristles can be wound evenly over the whole length of the base winding roll 13.

Particularly, in the case of the patterning machine, the operation speed of the yarn traveling through the bristle machining mechanism 12 is kept constant so that the nap is constantly formed on the surface of the yarn.

The rotational speed of the driving guide roll 26 disposed below the bristle machining mechanism 12 and the rotational speed of the driving tension rolls (not shown) of the sub- 25a are synchronized at the same speed, that is, the lower driving guide roll 26, which is driven at the same speed, pushes up the yarn constantly, and at the same time, the upper driving tension roll 25a rotates the yarn So that the yarn of the same length can be equally moved during the same time so that the baffle can be constantly formed on the surface over the entire length of the yarn.

Therefore, the yarn 100 loosened from the yarn supplying roll 10 is transferred to the warp knitting machine 12 having the bobbles on the surface thereof while passing through the yarn tension adjusting device 24, the driving guide roll 26, 200), and subsequently the warp yarn 200 is wound on the warp yarn take-up roll 13 after passing through the sub-tension portion 25 → the ring 29. Eventually, And the like.

Here, the power for driving the driving guide roll, the power for driving each roll of the sub-tension unit, the power for driving the ring movement shaft, the power for driving the wind-up roll driving roll, The means and method for providing power for driving the drive belt for rotating the spindle can be employed without any particular limitation as long as it is a means and a method commonly known in the art.

FIGS. 3A to 3E are perspective views showing a bristle machining mechanism of the apparatus for machining a primer according to an embodiment of the present invention, and FIG. 4 is a sectional view showing a bristle machining mechanism of a primer processing apparatus according to an embodiment of the present invention .

As shown in Figs. 3A to 3E and 4, the bristle machining mechanism 12 rotates the yarn around a central axis in a circular path and contacts the grinding stone 11 to form a boss on the surface of the yarn .

To this end, the bristle machining mechanism 12 includes a hollow spindle 17 as a means for turning the yarn in a circular trajectory.

The hollow spindle 17 has a circular shaft shape and a yarn through hole 14 penetrating along the central axis is formed on the inner side of the spindle so that the yarn can be moved up there and a circular plate formed on the upper end of the spindle, A yarn discharge port 15 is formed at a portion of the disk edge having a diameter relatively larger than the spindle diameter so that the yarn can be discharged through the discharge port 15.

An opening 31 communicating with the outside is formed on the side surface of the upper end of the hollow spindle 17 so that the yarn traveling along the yarn through hole 14 of the hollow spindle 17 passes through the opening 31 The yarn discharging opening 15 is inclined to the yarn discharging opening 15 located at the outer periphery spaced apart from the central axis and then can be moved upwardly through the yarn discharging opening 15. [

At this time, the hollow spindle 17 can be installed to be rotatable about its own axis while being supported by bearings 21b, which will be described later, at two places.

The hollow spindle 17 is driven to cross the horizontal spindle 17 in the vertical direction and can be rotated by the drive belt 16 in frictional contact with the outer peripheral surface of the hollow spindle 17, As a result, the yarn exiting the yarn outlet 15 of the hollow spindle 17 can be brought into contact with the grinding stone 11 while moving along the locus of the circle by the rotation of the hollow spindle 17.

The bristle machining mechanism 12 is provided with means for transferring the position of the hollow spindle 17 from the axial position to the outer position while supporting the hollow spindle 17, And a spindle position moving device 21 as means for moving the spindle housing 11 away from the position immediately below the grindstone housing 20 to which it belongs.

The spindle position shifting device 21 may be configured to move the hollow spindle 17 to one side in a situation such as setting the yarn on the hollow spindle 17 or replacing the grinding stone 11 in the grinding stone housing 20 And includes a fixed case 21a, a spindle case 21c, a spring 21d, and the like.

The fixed case 21a is fixed to the apparatus frame (not shown) by using a bolt fastening hole 21e at the rear end portion. A shaft portion 21f is formed at an upper end of the fixed case 21a installed as described above So that the spindle case 21c can be coupled thereto.

On the inner side surface of the rear end portion of the fixed case 21a and the inner side surface of the distal end portion, seating ends 21g-1 and 21g-2 for holding the center position and outer position of the spindle case 21c are respectively formed. The respective seating ends 21g-1 and 21g-2 can be positioned at an angle of 90 ° or more while facing each other along the rotational locus line of the spindle case 21c.

Accordingly, the spindle case 21c is seated and engaged in the respective seating ends 21g-1 and 21g-2 through the lower bearing support portion 21b at the center position and the outer periphery position, and can maintain its position.

The spindle case 21c supports the hollow spindle 17. The rear surface of the spindle case 21 is supported by a shaft 21f of the stationary case 21a. 21c can be rotated about the shaft portion 21f as a center axis.

The spindle case 21c is provided with two upper and lower bearing support portions 21b each having a bearing (not shown) therein. The hollow spindle 17 is coupled to each bearing support portion 21b at this time, .

A handle 21h is formed on one side of the spindle case 21c, for example, on the rear side of the case body, which is coupled to the shaft 33 of the fixed case 21a. The entire spindle case 21c including the hollow spindle 17 can be tilted to the center position or the outer edge position.

The spring 21d serves to hold the axial position and the outer position of the hollow spindle 17 and the spindle case 21c, that is, the hollow spindle 17 and the spindle case 21c, Or the hollow spindle 17 and the spindle case 21c are in a position in which they are displaced to one side of the grindstone housing 20. In this case,

The spring 21d is connected between the first spring pin 21i formed at one side of the bottom surface of the fixed case 21a and the second spring pin 21j formed at one side of the bottom surface of the spindle case 21c Respectively.

The axis of the spring 21d thus installed is positioned at a position offset from the line connecting the axis 21f of the fixed case 21a and the axis of the hollow spindle 17 of the spindle case 21c, And is located at an inner position biased by the bolt fastening point 21e, which is a supporting point of the fixed case 21a.

The entire spindle case 21c including the hollow spindle 17 is pulled up by the pulling force of the spring 21d in a state of being seated in the seating end 21g-1 of the inner side of the rear end in the fixed case 21a, So that it can receive the force of the spring 21d in the state of being seated on the seating end 21g-2 of the inner side of the distal end portion of the fixed case 21a after being bent outward The outer position can be maintained.

The bristle machining mechanism 12 includes a grinding stone 11 as a means for making a bobble to the yarn substantially in contact with the yarn and a means for supporting and holding the grinding stone 11, .

The grinding stone 11 is in the form of a cylinder having a baffle hole 18 through which a yarn passes at the center. The baffle can be formed on the surface of the yarn by contacting and scraping the yarn on the inner circumferential surface of the baffle hole 18 at this time.

At this time, since the upper inner diameter of the bopple hole 18 is relatively small as compared with the inner diameter of the lower end, it can be formed into a hole having a tapered cross section as a whole.

The grinding stone 11 can be made of a material such as diamond or stone and can be installed in a center groove of a grinding stone table 23a provided inside the grinding stone housing 20.

The grinding stone housing 20 is in the form of a circular tube and can be installed in a bolt or screw fastening structure on the apparatus frame side in a state of being coaxially positioned on the upper part of the hollow spindle 17. Inside the grinding stone housing 11, Of course, the grindstone table 23a supporting this can be accommodated.

A slot 19 is formed on the wall surface of the grinding stone housing 20 so as to be elongated in the vertical direction. The adjustment bolt 23b described later can be inserted into the slot 19 at this time.

The yarn advancing upward from the side of the driving guide roll 26 located below the bristle machining mechanism 12 enters the bottom surface of the hollow spindle 17 and thereafter passes through the yarn through hole 17 of the hollow spindle 17, The yarn coming out from the bottom through the hollow spindle 17 enters the bobbin hole 18 of the grinding stone 11 in the grinding stone housing 20 while passing through the hole 14 through the hole 14, And the circular yarn moving along the circular trajectory continues to touch and scratch the inner surface of the baffle hole 18, so that the baffle can be made on the surface of the yarn. Thus, the baffled yarn, To the side of the sub-tension part 25 located at the upper part of the main body 20.

The bristle machining mechanism 12 includes a center bar 22 as a means for guiding the yarn to proceed in an accurate circular path when the yarn advances while contacting and scraping the yarn in the grinding stone.

The center bar 22 is in the form of a circular bar having a step and is coupled to the upper end of the thread through hole 14 in the hollow spindle 17 in an interference fit using the lower support pin 32, .

The center bar 22 is fixed to the upper end of the hollow spindle 17 and is vertically installed along the central axis. The lower end portion of the center bar 22, It is possible to form a predetermined gap with the inner circumferential surface of the baffle hole by passing through the hole 18.

Thus, the circular arc of the grinding stone 11, which is drawn along a circle along the perimeter of the central axis of the Boppel while drawing a circle along the perforation 18, So that the yarn can be contacted and scratched on the side of the grinding stone while proceeding with the accurate trajectory of the circle, and as a result, the baffle can be formed uniformly and abundantly on the surface of the yarn as a whole .

The bristle machining mechanism 12 includes a grinding stone height adjusting device 23 as a means for varying the position of the grinding stone 11.

The grinding stone height adjusting device 23 is composed of a grinding stone table 23a, an adjusting bolt 23b, an indicator 23c, a ruler 23d and the like.

The grinding stone table 23a is installed concentrically inside the grinding stone housing 20 to support the grinding stone 11 and is installed in a structure capable of moving upward and downward together with the grinding stone 11. [

That is, the outer circumferential surface of the grinding stone table 23a is inserted and arranged in a structure in contact with the inner circumferential surface of the grinding stone housing 20, and can be installed in a structure supported by the fastening structure of the adjusting bolt 23b .

In the grinding stone table 23a, a groove portion is formed at the central portion of the upper surface, so that the grinding stone 11 can be received and accommodated therein.

The adjustment bolt 23b is a kind of wing bolt which is inserted through the slot 19 in the grinding stone housing 20 from the outside of the grinding stone housing 20 and then passes through the slot 19 on the outer peripheral surface of the grinding stone table 23a Respectively.

Accordingly, when the adjusting bolt 23b is fastened tightly, the head portion is pressed against the outer circumferential surface of the grinding stone housing 20 via a washer or the like, and is fastened to the grinding stone table 23a. So that it can be fixedly supported.

The indicator 23c is provided together with a structure interposed between the head portion of the adjustment bolt 23b and the outer circumferential surface of the grindstone housing 20 at the time of fastening the adjustment bolt 23b and serves to indicate the scale 23d .

The ruler 23d is a means for recognizing the degree of height adjustment to the user when adjusting the height of the grinding stone and is disposed on both sides of the slot 19 formed in the grinding stone housing 20. [

The user then loosens the fastening state of the adjusting bolt 23b and moves the position of the grinding stone table 23c including the grinding stone 11 upward or downward as desired. The height of the grinding stone 11 is confirmed at the position of the grinding stone 23d, and the grinding stone height can be arbitrarily adjusted by tightening the adjusting bolt 23b again in this state.

By adjusting the height of the grinding stone 11 for making the bobbins on the yarn through the operation of the grinding stone height adjusting device 23, the contact and scratching positions of the yarns can be arbitrarily varied, The degree of formation can be controlled in various ways.

For example, when the grinding stone 11 is positioned at the upper position, the baffles are made relatively less (compared to the downward position) on the surface of the yarn, and when the grinding stone 11 is positioned lower, It is made a lot.

That is, as the thread exits the yarn outlet 15 of the hollow spindle 17, the yarn passing through the baffle hole 18 of the grinding stone 11 to the upper portion of the sub-tension portion 25 has a substantially triangular cross- A trajectory of a triangular sectional shape in which the side of the yarn discharge port on which the circular trajectory is drawn is a base line and the side of the sub tension portion which advances in a straight line is a vertex) is drawn. In this state, when the position of the grinding stone 11 is moved downward, As the contact between the grinding stones increases, the number of the baffles becomes relatively large. On the contrary, when the position of the grinding stone 11 is moved upwards, the contact between the yarn and the grinding stones decreases and the baffle is relatively small.

FIG. 5 is a plan view showing a yarn tensioning mechanism of the apparatus for fabricating a magnetic pattern according to an embodiment of the present invention.

As shown in FIG. 5, the yarn tension adjusting device 24 maintains the tension of the yarn advancing to the bristle processing mechanism 12 side.

The yarn tension adjusting device 24 is disposed between the yarn supplying roll 10 side and the bristle processing mechanism 12 side, more specifically between the yarn supplying roll 10 and the driving guide roll 26, Thereby providing a tension.

To this end, a tension base 25d in a horizontal posture is provided on the apparatus frame. In the tension base 25d, a hole 24a and a thread outlet 24b in the form of a hole are formed at positions facing each other on the upper edge, And a circular seating groove 14c is formed at the center of the upper surface.

In addition, a disc-shaped tension rotating body 24f is seated in the seat groove 24c of the tension base 25d and is installed in a structure rotatable by a central shaft (not shown) of the bolt etc. in this state, The tension rotation body 24f of the torsion bar 24c is engaged and disengaged in the seat groove 24c to be rotatable and fixed.

For example, an uneven surface (not shown) is formed on the bottom edge portion of the seating groove portion 24c formed in the tension base 25d, An uneven surface (not shown) is formed at the bottom edge portion of the rotating body 24f in such a manner that the unevenness is repeated along the circumferential direction of the bottom surface and is engaged with the uneven surface in the seating groove portion 24c.

Accordingly, when the user rotates the tension rotation body 24f forcibly, the tension rotation body 24f can rotate. When the user rotates the tension rotation body 24f, the tension rotation body 24f rotates So that the angle-adjusted state can be fixed without turning by a predetermined force (tension applied to the yarn).

The tension rotating body 24f is provided with a pair of guide rolls 24e which serve to guide the yarn path and substantially impart tension to the yarn.

At this time, the guide roll 24e is provided in a freely rotatable structure. The guide roll 24e is disposed on the upper surface of the tension rotating body 24f so as to be parallel to each other and rotates the yarn inlet 24a and the yarn exit 24b, the tension of the yarn can be changed while changing the path of the yarn.

For example, when the pair of guide rollers 24e are positioned in a line between the yarn inlet 24a and the yarn outlet 24b, no tension is applied to the yarn (a).

In this state, when the user rotates the tension rotating body 24f including the pair of guide rolls 24e in one direction, for example, clockwise by about 45 degrees, In addition, as the path is changed (the path becomes longer), the pulling force is applied, so that a constant tension can be given to the yarn (b).

In this state, when the user rotates the tension rotation body 24f including the pair of guide rolls 24e clockwise by about 90 degrees, the yarn running on the pair of guide rolls 24e is further changed in path (C) a certain tensile force can be imparted to the yarn as the yarn is further tensioned.

A bolt hole 37 is formed at one side of the outer circumferential surface of the grindstone housing 20 so that an adjusting bolt 36 described later can be fastened to the bolt hole 37.

Particularly, the housing bracket 33 is formed with a bracket slot 35 that is long and slender in the vertical direction, and the adjustment bolt 36, which will be described later, can pass through the bracket slot 35 at this time.

The yarn coming from the bottom through the hollow spindle 17 of the bristle machining mechanism 12 enters the bobbin hole 18 of the grinding stone 11 housed in the grinding stone housing 20, The bobbin may be formed on the surface of the yarn by contacting and scratching the inner surface of the bobbin hole 18. The bobbin-shaped yarn, that is, the bristle yarn, It is possible to proceed to the side of the sub-tension part 25 located.

Since the bristle yarn at this time has the bopples after the friction with the grinding stone 11 and at the same time the upper and lower length sections of the grinding stone 11 are immediately passed out and the wiping yarn is formed upwardly, It becomes possible to manufacture a machine having a clean quality baffle.

In particular, the grinding stone housing 20 is installed in a structure that can vary the position of the grinding stone 11 accommodated therein.

The grinding stone housing 20 is closely attached to the front surface of the housing bracket 33 and the bolt hole 37 in the outer circumferential surface of the grinding stone housing 20 is inserted into the bracket slot 33 from the rear surface of the housing bracket 33 35 and the adjustment bolt 36 is fastened so that the grinding stone housing 20 can be moved up and down together with the grinding stone 11 through the locking and releasing operations of the adjusting bolt 36 .

The adjustment bolt 36 is a kind of wing bolt and is fastened to the bolt hole 37 of the grindstone housing 20 after passing through the bracket slot 35 from the rear side of the housing bracket 33.

Accordingly, when the adjusting bolt 36 is fastened tightly, the head portion is pressed against the rear surface of the housing bracket 33 via a washer or the like and is fastened to the grinding stone housing 20, So that it can be fixedly supported.

The position of the grinding stone housing 20 including the grinding stone 11 is appropriately shifted upward or downward by a desired height after the user temporarily loosens the fastening state of the adjustment bolt 36. In this state, ), The height of the grinding stone can be arbitrarily adjusted.

By adjusting the height of the grinding stone 11 that makes the bopple on the yarn, the contact and scratching positions of the yarn can be arbitrarily changed, and thus the degree of formation of the boppel formed on the surface of the yarn can be variously adjusted.
