Description

{Vertical Hook Cutting Equipment For Suture}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic barb forming apparatus for forming a barb on a surgical wire used for sewing muscles or skin of a person in a surgical suture of a person or an animal, Which can automatically form a plurality of barbs at all positions along 360 degrees along the longitudinal direction of the bar, and to uniformly form the protrusion height, thickness, and the like of the barbs.

In general, when a suture is performed using a suture (wire, thread) in a suture operation, especially a plastic surgery, the effect of the molding is reduced to a half, and the skin tissue is not fixed or held.

Many other methods (cosmetics, massages, etc.) have been used, however, as the interest in maintaining the age or preventing aging of the skin has increased in recent years, but the effect can not be expected directly, It is a reality.

Accordingly, in place of the surgical suture (hereinafter collectively referred to as a wire) conventionally used in conventional suturing surgery, particularly in wrinkle removing cosmetic surgery, a barb protruding in one direction on the outer circumferential surface of the wire, There have been proposed a number of techniques related to wire that can not only hold it fixed but also can easily remove wrinkles by pulling it.

As a prior art relating to such a surgical wire, Korean Patent Laid-Open No. 10-2005-0108494 (November 17, 2005) entitled "

The present invention relates to an operating room for plastic surgery used for wrinkle removal surgery and the like. More specifically, the present invention relates to an operating room for a plastic surgery, The protrusions are formed to be pointed obliquely toward both ends with the center baseline as a center with respect to the longitudinal direction of the thread having a certain length.

In order to form and form a protrusion (hereinafter collectively referred to as a barb) on the outer circumferential surface of an operating room (hereinafter collectively referred to as a wire) according to the present invention, the structure and operation of the manufacturing apparatus must be very precise and finely formed.

In other words, unlike a general thread, a surgical wire has a very thin thickness. Therefore, in order to form fine barbs with uniform height and thickness on such a thin wire, the molding operation must be precisely performed. The precision of molding is deteriorated. Therefore, in the case of the fine wire, the worker manually forms the barb through manual operation without using the automated molding device.

In addition, although the surgical wire used in the cosmetic surgery for removing wrinkles has been illustrated and described in the description of the 360-degree barb forming automation equipment of the vertical wire according to the present invention, it is not limited thereto,

The term 'wire' or 'surgical wire' is used only as a representative word to refer to a sealing member (thread) used in surgery. The present invention can be applied not only to surgery but also to all kinds of wires having barbs And therefore the nature of the wire described in the present invention includes all kinds of threads and lines, and the scope of protection of the present invention should not be limited by the term referred to in the detailed description.

Hereinafter, a 360-degree barbed automation apparatus for a vertical wire according to the present invention will be described with reference to the accompanying drawings.

As shown in FIGS. 1 to 11 (hereinafter referred to as a wire-related configuration is shown in FIG. 12), the automation equipment for forming a 360-degree barb of a vertical wire according to the present invention is a device for partially cutting the outer circumferential surface of a wire W, The drawing unit 500 includes a wire winding unit 100, a discharging unit 200, a pulling unit 300, a forming unit 400, and a take-out unit 500 for finally discharging a bar- .

A molding part 400 including a cutout part 440 and a turntable 401 is installed at the center of the base plate 10 and a discharge part 200 and a winding part 300 are formed on an upper plate 11 provided on the base plate 10, And the wire W supplied from the winding portion 100 is pulled out from the discharging portion 200 through the pulling portion 300 so that the wire is wound around the forming portion 400 in the vertical direction.

First, the wire supplied from the winding unit 100 is made of a soft, elastic, and harmless material for the human body, for producing a surgical wire used in surgical operations such as a sewing operation or a wrinkle removal molding operation. The wire bundle (not shown) wound on the wire 110 is unwound and supplied to the discharge unit 200.

The material of the wire is made of polypropylene, but it also includes a soluble material such as gold, stainless steel and polydiaxonone.

In addition, the wire may be made to have various grades and thicknesses depending on the material and the purpose of the operation.

As shown in FIGS. 1 and 2, the winding drum 110 is for supplying a wire W discharged to the discharge unit 200. Here, the supply means is such that the winding drum 110 rotates directly, This means that the pulling portion 300 pulls the wire end of the discharging portion 200 so that the supply of the wire is passively performed.

At this time, the winding unit 100 allows the wire between the discharging unit 200 and the winding drum 110 to be supplied in a state of being always kept in tension through the tension adjusting unit 120.

This is because the winding drum is rotated by the vibration due to the operation of the equipment so that the wire between the winding drum 110 and the discharging part 200 is prevented from being loosened when the wire is discharged by the pulling part 300 to be.

As shown in FIGS. 1 to 4, the tension adjusting means 120 is coupled to one side of the winding drum 110 and rotates together. The tension adjusting means 120 includes a plurality of A rotary plate 121 having first and second insertion holes 121A and 121B,

The first and second insertion holes 121A and 121B are provided at one side of the rotation plate 121 and elastically supported to be inserted into the first and second insertion holes 121A and 121B, The first and second fixing rods 122A and 122B arranged so as not to interfere with each other.

More specifically, the first rotary shaft 111 of the winding drum 110 is coupled to the 1-1 vertical frame 101 coupled to the upper plate 11, 101 are installed so that the winding drum 110 and the rotary plate 121 rotate together.

A plurality of first and second insertion holes 121A and 121B are perforated in the circumferential direction around the first rotary shaft 111 of the winding drum 110 in the rotary plate 121. In the first and second insertion holes 121A and 121B, The insertion holes 121A and 121B are formed so as not to be arranged on the same line with respect to a center line (an arbitrary extension line forming a radius) connected to the outer side of the rotary plate 121 at the first rotary shaft 111, respectively.

That is, the rotary plate 121 is disposed such that the first insertion holes 121A and the second insertion holes 121B cross each other in the circumferential direction.

A first driving means 123 (for example, a pneumatic cylinder) is provided in the first and second vertical frames 102 coupled to one side of the 1-1 vertical frame 101,

The first vertical frame 101 is moved forward and backward by the first driving means 123 between the first and second vertical frames 101 and 102 (Not shown).

When the pressing plate 122 is advanced by the first driving means 123 and the first or second fixing rod 122A or 122B is inserted into the first or second insertion hole 121A or 121B The winding drum 110 is not rotated,

When the pressing plate 122 is moved backward by the first driving means 123 and the first or second fixing rod 122A or 122B is released from the first or second insertion hole 121A or 121B As the winding drum 110 rotates in accordance with the lifting and lowering of the pulling portion 300 or the pulling portion 300 and the discharging portion 200, the wire is unwound.

At this time, the first and second fixing rods 122A and 122B are disposed along the circumferential direction about the center of the rotary plate 121 so as to correspond to the arrangement of the first and second insertion holes 121A and 121B The interval or the angle of arrangement between the first and second fixing rods 122A and 122B is different from the interval or the arrangement angle between the first and second insertion holes 121A and 121B, Is formed larger or smaller.

This is a configuration for finely setting the fixing angle of the winding drum 110 irrespective of the length of the wire W to be unwound, that is, the rotation radius or the number of revolutions of the winding drum.

That is, when the insertion holes are arranged in a row in the circumferential direction on the rotary plate 121, the angle at which the fixing rod is inserted into the insertion hole and the winding drum 110 is fixed is limited to the interval between the insertion holes,

The present invention is characterized in that the rotation of the winding drum (110) is performed by inserting any one of the first or second fixing rods into the first or second insertion hole by changing the interval or the arrangement angle of the insertion holes and the fixing rods The stop position can be adjusted more precisely.

That is, when the first fixing rod 122A is inserted into the first insertion hole 121A, the second fixing rod 122B is not inserted into the second insertion hole 121B, (Rear surface) is maintained,

On the other hand, when the second fixing rod 122B is inserted into the second insertion hole 121B, the first insertion hole 121A is not inserted into the first insertion hole 121A, Back surface) is maintained,

The rotation of the winding drum can be stopped and fixed through the operation of the first driving means irrespective of the length of the wire being unwound while the winding drum 110 is rotated.

The first or second fixing rods 122A and 122B are repeatedly moved to the first and second fixing rods 122A and 122B repeatedly each time the wire pulled by the pulling portion 300 pulls the wire and the wire unwound from the winding drum 110 completes the discharge of a predetermined length, The winding drum 110 is fixed to the winding drum 110 through the tension roller 125 which will be described later in a state in which the winding drum 110 is fixed in such a state that the winding drum is fixed while being pulled into the second insertion holes 121A, 200 can be kept in a tension state to prevent the wire from becoming loose.

On the other hand, a deceleration member 124 is installed on one side of the 1-1 vertical frame 101 so as to swing toward the rotation plate 121.

The deceleration member 124 is connected to the opposite end of the swing shaft 124A and the annular portions provided on the vertical frame 101 by the third to third elastic bodies 124a, It is possible to restrict the rotation speed of the rotary plate 121 additionally by forcibly bringing the wire into contact with the side surface of the rotary plate 121,

Reference numeral 112 denotes a handle for fixing the winding drum 110 on the first rotating shaft 111. Reference numeral 113a denotes a bolt 113 for coupling the winding drum 110 and the rotating plate 121 to vibration. And the elastic bodies press the bolts in the engagement direction to prevent them from being released.

The tension adjusting means 120 includes one or more tension rollers 125 arranged in a zigzag manner between the discharging portion 200 and the winding portion 100.

The first to third vertical frames 103 coupled to the upper plate 11 are provided with guide rollers 128 and 129 for guiding the wire W unwound from the winding drum 110 to the discharge portion 200, One or more tension rollers 125 arranged in a zigzag form up and down (or left and right) with respect to the guide roller are provided so that the wire between the discharge portion 200 and the winding portion 100 maintains a tension greater than a certain level, To be transported.

The tension roller 125 is installed so as to be adjustable up and down (or right and left) along the first guide part 126 coupled to the rear surface of the 1-3 vertical frame 103,

The tension roller in which the height (or the right and left position) is displaced by the fourth to fifth elastic bodies 125a connecting the first to third vertical frames 103 and the tension roller 125 is set to be elastic So that the wire can be held in a taut state.

The guide roller 214 (refer to Fig. 5) of the discharge portion 200, via the guide rollers 128 and 129 and the tension roller 125, in the take-up drum 110, The wire W is held in an up-and-down (or left-right) zigzag pattern so that the tension is kept constant.

That is, when the wire is connected between the winding drum 110 and the discharging unit 200 in the lateral direction of the general straight line, the wire may be loosened by the weight of the winding drum 110,

The present invention can solve the above problems by causing the wire between the winding drum 110 and the discharging unit 200 to be guided and conveyed in a staggered manner by the tension roller 125. [

At this time, if the elastic holding force of the first to fourth elastic bodies 125a is too strong, the wires may not be loosened or broken, so that the specifications of the elastic force of the fourth to eighth elastic bodies 125a vary depending on the thickness of the wire, .

A stopper (not shown) for restricting the height (or the lateral position) of the tension roller 125 may be introduced to prevent the tension roller 125 from pulling the wire more than necessary.

In the figure, it can be seen that one tension roller 125 which is adjusted in height up and down is installed below the guide rollers, where the elastic support direction, height, number and the like of the tension roller 125 are set such that the wire is staggered The present invention is not limited to the drawings of the present specification.

The first cylinder 210 is slidably coupled to a rail 203 installed on the second vertical frame 201 so that the first cylinder 210 moves upward and downward by various motions such as a motor or a pneumatic cylinder Means 202. For the sake of convenience of explanation, the detailed description of the elevating means 202 will be omitted.

The first cylinder 210 has a hollow 211 penetrating along the longitudinal direction and a guide roller 214 is provided on the hollow upper side so that the wire of the winding unit 100 is guided by the guide roller 214 (See FIG. 8) of the first cylinder 210, and is discharged from the lower side of the pulling portion 300, which will be described later.

A fixing means 213 for fixing a wire W exposed to the discharge port 212 is provided on the discharge port 212 to fix a wire discharged to a predetermined length (length of the wire to be formed) It is possible to prevent the wire from being displaced from the correct position when discharging the wire due to the rising or falling of the forming or discharging portion 200 and the pulling portion 300 by the wire 400.

The fixing means 213 may be implemented in various manners. In the figure, a pair of fixing means 213 is installed to be drawn in and out through the driving means such as a pneumatic cylinder provided on both sides of the discharge opening 212 of the first cylinder 210 A fixing plate (not shown) is introduced so that the fixing plates slide in opposite directions to each other and are pressed and fixed by the wires discharged between the fixing plates.

6, 7, and 11, a top surface of the turntable 401 is provided with a first rail (not shown) formed in the longitudinal direction of the turntable, and is slidably coupled to the first rail A machining unit 430 equipped with a rotating cutter 440 is provided on a moving plate 431 for moving forward and backward.

The cutting unit 440 is provided on the machining unit 430 so as to be offset to one side of the wire W fixed in the vertical direction and the machining unit 430 The incision portion 440 approaches the lateral direction of the wire W when the wire W is advanced in the direction of the wire W so that one side of the wire W can be partially cut.

The fixed frame 411 is coupled to the turntable 401 at a position opposite to the blade 441 of the cutout portion 440 advanced with respect to the vertically fixed wire W,

The supporting member 410 is slidably coupled to a rail 412a of the fixed frame 411 and is installed to move back and forth toward the wire W by a driving means 412 such as a pneumatic cylinder.

The support member 410 is moved forward toward the wire W before the incision part 440 advances in the direction of the wire W to form the barb S on one side of the wire W, The cutout portion 440 forms the barb S on one side of the wire W in a state where the end of the support member 410 supports the other side of the wire W. [ That is, the support member 410 performs the same function as the cutting board during the partial cutting operation of the cutout portion 440.

In the figure, two supporting members 410 are provided in the opposite directions, one supporting member can be selectively used according to an approaching direction (a forwarding position) of the incising member 440, and an unused supporting member So that the approach path of the incision 440 can be secured.

When one barb S is formed through the incision 440, the turntable 401 is rotated in one direction so that the incision 440 is moved to another barb S at a position different from the first barb S, When the pulling portion 300 and the discharging portion 200 are lifted and lowered by repeating these operations, the wire W formed by the present invention moves along the longitudinal direction and the circumferential direction (360 degrees) A plurality of barbs S are formed at different positions (see FIG. 13).

At this time, the cut-off portion 440 is simultaneously rotated and swung with respect to the wire W through the machining unit 430 and the rotation of the second rotation shaft 441 so that a predetermined inclination angle is formed on the outer circumferential surface of the wire W Thereby forming the barbs S having the barb.

That is, the cut-off portion 440 forms a trajectory in the shape of a line after the blade 442 of the cut-out portion 440 contacts the one side of the wire W in the oblique direction, After that,

The incision portion 440 rotates in both directions at the point where the swing motion is finished so that the partially incised barb S is projected outward (a kind of lifting operation) to the outside of the wire W as shown in Fig.

To this end, as shown in Figs. 7 and 11, the processing unit 430 of the present invention

A first moving plate 432 coupled to move laterally in the moving plate 431,

A second moving plate 433 coupled to the first moving plate 432 so as to vertically move vertically,

And a cutout portion 440 connected to the second rotating shaft 441 so as to be rotatable on the second moving plate 433.

More specifically, the second guide 432a of the first moving plate 432 is provided at the upper portion of the moving plate 431 in the horizontal direction, 2 sliding portion 431a,

The third guide 433a of the second moving plate 433 is provided on the third rail 433a in the vertical direction on the front surface or the rear surface of the first moving plate 432, 432b.

When the second moving plate 433 is coupled to the rear surface of the first moving plate 432 as shown in the figure, the first moving plate 432 has the through hole 432A, and the second moving plate 433 So that the incision part 440 provided on the first moving plate 432 can be exposed to the front of the first moving plate 432.

At this time, the movement of the first and second moving plates 423 and 433 may be such that the movement can be forced through a driving means such as a pneumatic cylinder. However, the present invention is not limited thereto, 1 and a pair of cams 435 and 436 for forcing the movement of the second moving plates 423 and 433 are introduced.

The first moving plate 432 may be provided at one of the left and right sides of the first moving plate 432 so as to press the left or right side of the first moving plate 432, A first cam 435 for moving the first cam 435,

A second cam 436 provided on either the upper or lower side of the second moving plate 433 in the fixed plate 434 to vertically move the upper or lower surface of the second moving plate 433,

And elastic means (not shown) for returning the moving plates moved by the cams back to their original positions.

The first and second cams 435 and 436 are installed to rotate on the fixed plate 434 through respective eccentric shafts 435A and 436A,

The first and second cams 435 and 436 have wide portions 435a and 436a and narrow portions 435b and 436b having different widths with respect to the eccentric shafts 435A and 436A.

That is, the first and second cams 435 and 436 in the form of cylinders are axially supported by eccentric shafts 435A and 436A which are biased to one side instead of the center, so that the wide portions 435a and 436a and the narrow portions 435b and 436b Is formed.

When the cams 435 and 436 rotate in one direction and the wide portions 435a and 436a contact one surface of the moving plates 432 and 433, the moving plates 432 and 433 are moved in the pressing direction by the pressure,

When the cams 435 and 436 are rotated in the other direction, the pressing of the wide portions 435a and 436a is released and the moving plates 432 and 433 are moved back by elastic means to contact the narrow portions 435b and 436b .

11, due to the operation of the cams 435 and 436 provided on the fixed plate 434, the right lateral movement of the first moving plate 432 and the lower lateral movement of the second moving plate 433 are simultaneously performed The cutting section 440 performs a right downward swing movement so that the blade 442 of the cutout section 440 contacts the one side of the wire W in an oblique direction in an oblique direction, (S) is formed.

When the cutter 440 is rotated in both directions by a motor (not shown) or the like at a point at which the blade 442 completes partial cutting in the form of an arc on one side of the wire W, The barbs 442 lift the barbs S so as to be bent outwardly of the wire W and project them.

That is, when the incision 440 is rotated in one direction (clockwise in the drawing) at the point where the incision 440 cuts the barb S through the right downward swing motion, the blade 442 of the incision 440, So that the barb S is partially incised in a similar " b " shape,

When the cutter 440 is rotated in the other direction (counterclockwise in the drawing), the blade 442 of the cutter 440 protrudes the barb S partially cut out from the wire W, The hooking function of the barb S can be maximized,

After the barb S is formed, the cutter 440 is returned through the left upward swing motion, and the blade 442 is detached from the wire W. [

In this case, it is more preferable that the rotation of the incision part 440 is repeatedly performed bidirectionally twice or three times for the stability of molding of the barb S.

The arrangement direction of the cutting section 440 forming the barbs and the direction of the swing motion and the rotational movement of the barbs form a bar S with respect to the wire W in the direction of forming and protruding the barbs S, Depending on whether it is projected in the upward direction or in the downward direction,

Further, it is apparent that the projecting height of the barb S varies according to the bi-directional rotation angle of the cut-off portion 440,

Accordingly, it is possible to freely adjust the arrangement direction of the cut-off portion 440 and the angle of the swing motion and the rotational motion, so that the barb S can be formed according to the specification of the wire W.

In this case, although not shown in the drawing, an inspection means such as a vision camera is further installed on the turntable 401 of the forming unit 400 to detect the barb S of the wire W in real time.

The inspection means is disposed at a position that does not interfere with the forward and backward movement of the processing unit 430 and the receiving member 410, and interlocks with the control means (not shown) to determine whether or not the barb formation is defective.

For example, at nighttime unmanned operation without an operator, the inspection means compares and analyzes the degree of barb forming (depth, angle, protrusion height, etc.) of the wire W being processed at present based on the barb forming information of the good article, The machining of the barb forming apparatus can be automatically stopped when the difference between the barb forming information of the good article and the barb forming degree during the machining is about 10%.

This is to prevent wasting of the wire because the wire for surgery W is relatively expensive, unlike a general thread.

2 and 5, the take-out unit 500 includes a take-out member 510 for fixing the formed wire W and discharging the cut wire W,

And a cutting member 520 for cutting a wire W fixed by the take-out member 510 from one side of the discharge part 200.

The take-out member 510 is slidably coupled to a rail 11a provided on the upper plate 11 and is transversely moved along the rail portion through a driving means 512 such as a motor,

The gripping unit 511 is provided in the direction of the discharging unit 200. When the forming of the wire W is completed, the taking-out member 510 moves in the direction of the discharging unit 200, In a state in which the formed wire W (that is, the upper end portion of the wire W exposed to the discharge portion 200) is fixed,

When the upper end of the wire W held by the cutting member 520 is cut, the take-out member 510 returns to its original position and the grip 511 is opened, (Not shown) and finally discharged.

The cutting member 520 is slidably coupled to a rail 523a of a horizontal bar 523 coupled to one side of the discharge unit 200 and the lower portion of the upper plate 11, And a cutting blade 521 is provided in the direction of the discharge part 200 so that after the wire W is formed, the take-out member 510 is moved forward and backward along the rail W by driving means (not shown) The cutting member 520 is instantaneously advanced toward the discharge portion 200 so that the wire W is cut by the cutting blade 521. [

Hereinafter, the operation of the wire (W) forming apparatus according to the present invention will be described in detail with reference to the drawings.

The wire bundle of the winding drum 110 is loosened and the wire W is fed to the discharge port 212 of the discharge portion 200 via the guide rollers 128, 129, 214 and the tension roller 125, Is set to be exposed.

8, the pulling portion 300 rises and the end of the wire W exposed to the lower portion of the ejection port 212 is moved upward by the rotation of the jaws 311 ),

9, the pulling portion 300 is lowered, and the wire W is discharged from the discharging portion 200 to a predetermined length.

10, when the discharging of the wire W is completed, the fixing unit 213 of the discharging unit 200 is operated to fix the upper and lower ends of the exposed wire W, So that the exposed wire W is placed on the forming part 400. [0052] As shown in FIG.

When the wire W is loosened or stopped in the winding drum 110, the tension adjusting means 120 feeds and feeds the wire W while maintaining the tension of the wire W at all times.

6, the moving plate 431 moves forward in the direction of the wire W to approach the cutout portion 440 in one direction of the wire W. As a result, At the same time, the receiving member 410 advances toward the other side of the wire W to support the other side of the wire W.

In this state, when the swing motion of the machining unit 430 shown in Figs. 7 and 11 and the rotational movement of the cutout portion 440 are sequentially performed, one barb S is attached to the outer peripheral surface of one side of the wire W, (W).

When the forming of one bar S is completed, the discharging part 200 and the pulling part 300 are accompanied by the lowering of the predetermined height again. At the same time, the turntable 401 rotates in one direction, The cutting section 440 forms the barbs S at different heights and different positions from the initial barbs S,

When the other barb formation is completed, the discharging part 200 and the pulling part 300 are descended together and the turntable 401 is rotated in the other direction so that the barbs S are formed at another height and position do.

As shown in FIG. 12, when the accompanying downward movement of the discharging unit 200 and the pulling unit 300, the bi-directional rotation of the turntable 401, and the partial incision of the cutout unit 440 are repeated, The barbs S can be formed into various shapes.

At this time, if the barb S is formed by the cutout portion 440, the tension of the wire W fixed between the discharge portion 200 and the pulling portion 300 can be weakened.

That is, as the barbs S are partially formed and the wire W is partially cut, a difference in thickness is generated between the incised portion and the uncut portion. As a result, the tension of the wire W in a tense state is loosened, The support of the wire W through the support member 410 is unstable and the height and thickness of the formed barbs S are not uniform and this error is caused by the barb S ) Becomes larger as the molding progresses.

Therefore, when the discharging unit 200 and the pulling unit 300 are simultaneously lowered and stopped during the wire W forming operation by the cutout unit 440, the lowering speed of the pulling unit 300 The speed of the discharging unit 200 is lower than that of the discharging unit 200.

That is, since the wire W to be formed is fixed at a predetermined length, the pulling portion 300 is moved at a finer speed (for example, about 1.05 times faster than the speed of the discharging portion 200) The lowering distance of the pulling unit 300 is longer than the lowering distance of the discharging unit 200. As a result, the upper end of the wire W is lowered to the discharging unit 200 It is possible to prevent the wire W from being deformed by the cut portion 440 because the lower end portion is pulled by the pulling portion 300 in the fixed state.

Since the upper and lower ends of the wire W to be formed (that is, the portion where the wire W is exposed to the discharge port 212) are fixed by the fixing means 213 and the jaw 311, And the portion drawn by the pulling portion 300 is a portion where the forming of the barb S has already been completed, so that the gap between the barbs is not changed.

Since the degree of loosening at the time of partial dissection may vary depending on the material of the wire W to be formed, the thickness, the cutting depth of the barb S,

The pulling portion 300 is lowered (more precisely, finely and rapidly) faster than the discharging portion 200, which means that the speed of the wire W can be maintained to be lowered and tightened,

In the present specification, the velocity difference between the ejection portion 200 and the pulling portion 300 is not numerically limited so that the right interpretation of the present invention should not be limited.

The machining unit 430, the moving plates 432 and 433, the cut-out portion 440, and the receiving member 410 are moved in a direction The turntable 401 returns to its original position and prepares for the next forming operation.

When the return operation is completed, the discharging unit 200 and the pulling unit 300 are raised together.

When the completion of the completion of the forming of the wire W is completed, the take-out member 510 transversely moves toward the wire W so that the gripper 511 holds the upper end of the formed wire W, The cutting member 520 is operated to cut the upper portion of the wire W fixed by the gripper 511. [

When the cutting operation is completed, the tub 311 releases the fixed end of the formed wire W. When the take-out member 510 returns to its original position and the gripping operation of the gripper 511 is released, It falls down into a container and is stored.

The pulling part 300 rises again toward the discharging part 200 so that the part of the wire W exposed to the discharging part 200 through the tub 311 The end is pulled to discharge and fix the wire to the molding preparation position,

As the series of operations is repeatedly performed, the present invention can automatically produce the wire bundle wound on the winding drum 110 by cutting it into a surgical wire of a predetermined length formed with barbs.

In the description of the present invention, the wires that are discharged in the vertical direction from the upper side to the lower side of the base plate 10 are exemplarily described as being representative of the wires, with reference to the accompanying drawings. However, It is obvious that the wire forming apparatus of the present invention can be manufactured by reversing the vertical arrangement of the winding unit 100 and the discharging unit 200 and the pulling unit 300. In this case, And the movement toward the pulling part 300, but the specific configuration is the same,

Accordingly, while the present invention has been described with reference to the automatic apparatus for forming a 360-degree barb in a vertical wire having a specific shape, configuration and structure, the present invention can be variously modified, changed and substituted by those skilled in the art, Should be construed as falling within the scope of protection of the present invention.

In the above description, conventionally known techniques relating to control means, power means, position adjusting means, and the like for various operations control of the specific configurations of the 360 degree barb forming automation equipment of vertical wire are omitted, but those skilled in the art can easily guess And can be inferred and reproduced.
