The present invention relates to a storage active feeding device, and more particularly, to a storage active feeding device for yarn feeding such as feeding yarns from bobbins to textile machines such as knitting machines, circular knitting machines and the like.

The textile industry seeks to strengthen international competitiveness and induce the technological development of textile machinery through the modernization of facilities, and related companies and researchers are making great efforts to realize this.

Textile machinery is a general term for machinery used for manufacturing, processing, and processing fibers, and the quality of textiles is absolutely dependent on the performance and technical level of textile machinery.

Textile machinery manufactures flat knits, woven fabrics, non woven fabrics, and braid fabrics by using straight yarns or filament yarns. Machine.

The circular knitting machine corresponding to the textile machine refers to a knitting machine mainly for knitting knitted garments among circular knitting machines, and is known as a knitting machine having high productivity and economy among various knitting methods.

Circular knitting machine is used with a feeding device for supplying the yarn necessary for knitting to the needle (needle), wherein the sharp spinning device has a different configuration depending on the circular knitting machine or feeding method.

'Yarn feeding' means to feed yarn to bobbins after an intermediate process from bobbins.

Such a process of yarn feeding includes a first process of primarily supplying yarn between the bobbin and the yarn feeding device; A second step of winding the yarn in the accumulation drum of the yarn feeding device and accumulating the yarn in the form of accumulation yarn; It may be divided into a third process of supplying the accumulation yarn to the circular knitting machine between the feeding device and the knitting machine (eg, circular knitting machine).

In this case, a first tension is applied to the yarn between the bobbin and the yarn feeding device, and a second tension is applied between the yarn feeding device and the knitting needle of the knitting machine, and the first tension is generally relatively higher than that of the second tension by a tension regulator or the like. Big. The knitting needle of the knitting machine performs a knitting motion at a predetermined sudden sudden power (hereinafter, referred to as 'rapid sudden force') and yarn speed in accordance with the knitting corresponding to the second tension.

As a related art related to proper sudden power, Korean Patent No. 10-468459 discloses a tension control device for a yarn feeder. This prior art is provided with a rotating wheel and a rotating cap which rotate by a rotating belt to wind the yarn on an accumulation drum. In addition, in the conventional technique, since the rotation wheel rotates in the release direction under normal tension, the yarn is continuously wound at the upper side of the accumulation drum and the yarn is continuously released at the lower side to the knitting machine.

This prior art is expected to detect the tension of the yarn automatically and repeatedly without stopping the loom within the maximum allowable tension range by varying the range of allowable tension given to the yarn.

In practice, however, the prior art stops the operation of the knitting machine in order to absorb the tension generated during the operation of the knitting machine, although it is possible to automatically accumulate yarn in the accumulation drum when the knitting machine is stopped.

In this conventional technique, tension is generated a lot during the operation of the knitting machine, and each time the productivity of the knitting machine has to be stopped because the operation of the knitting machine has to be stopped. The sudden supply of goods is impossible.

In addition, the tension control device of the yarn feeder of the prior art does not consider any inertia force due to the rotation of the rotation wheel, there is a disadvantage that a lot of operating error occurs.

Meanwhile, other conventional technologies related to the feeding device include a general feeding device, a jacquard feeding device, and a stripe feeding device.

Conventional general-purpose steep gear absorbing the first tension applied to the yarn between the bobbin and the yarn feeding device (hereinafter referred to as 'first tension absorption') and there is no control function for this, the yarn cutting phenomenon occurs It has disadvantages such as deterioration of fabric quality and attachment of a separate auxiliary control device. In addition, the general-purpose steep spinneret is a direct drum accumulating and feeding method by the rotating belt and the accumulation drum and the rotating wheel, it is impossible to feed at various variable speeds. In addition, general purpose steep spinners have a relatively low productivity as the yarn is accumulated by manual setting of the yarn or by hand cutting the yarn or the accumulation yarn.

Conventional jacquard steep gears also do not have a first tension absorption and a control function therefor, and simply take the yarn on the accumulation drum. Accordingly, the jacquard spinneret should be further attached to the lower part of the accumulation drum, and at this time, the eyebrow ring corresponding to the type of yarn is required, and the replacement of the eyebrow ring is required, and the wear of the eyebrow ring is required. The tension due to the phenomenon is not constant, and there is a disadvantage in that replacement costs are incurred. In addition, the jacquard spinneret has the disadvantage that additional processing is required depending on the particular yarn.

The conventional feeding device for stripe also has no first tension absorbing and control function for the same, and the rubber roller rotates or the tape feeder is operated to feed the yarn while pushing the yarn. Accordingly, the steep strip for the stripe has a disadvantage in that the replacement cost is caused by the wear of the rubber roller, and the quality of the fabric is deteriorated due to the imbalance of yarn tension as a direct supply method, rather than the accumulation rotation method of the accumulation drum.

In addition, the chemical fiber yarn to be used in the stripping yarn feeder, the rubber roller, or slipped in the tape feeder, causing the problem of difficulty in knitting production, or greatly reduce the productivity. In addition, the conventional steep steak for stripe has a disadvantage that it is impossible to supply steep at various speeds because the rotating belt is used to rotate the rubber roller, a separate auxiliary device is required.

In conclusion, the conventional yarn feeding devices have different types due to yarn types and yarn feeding characteristics, and can only be used for circular knitting machines suitable for the yarn feeding device, and cannot be used in a complex application.

In addition, since the conventional yarn feeding device mostly uses a rotating wheel or a rotating belt, it does not actively respond to the diversification of the yarn feeding speed.

In addition, the storage type dispensing apparatus according to the prior art has a disadvantage that the wind surface (wind) generated during the sudden death is introduced into the storage type dispensing apparatus, there is a risk of deterioration of the operating performance.

An object of the present invention devised to solve such a problem is a reed to repeatedly perform a reverse spiral motion such as floating motion and a spiral motion such as returning motion in response to the operation of the knitting needle. It is intended to provide a storage active steep spinner which allows the yarn to accumulate in the accumulator quickly and stably and can replace all of the previously mentioned steep spinnerets.

Another object of the present invention is to provide a storage active steep spinneret which can prevent overlapping yarns by means of accumulating pins arranged in a circular shape around the accumulator.

In addition, another object of the present invention is to overcome the problems of the conventional general feeding device, the jacquard feeding device, the stripping feeding device, to provide a storage active steeping value that can actively respond to the diversification of the feeding speed I would like to.

In addition, another object of the present invention is to have a separate lead portion that is independent of the 'accumulated yarn simultaneous supply function' in the accumulator, and a motor to rotate such a lead portion, the lead portion of the bobbin side yarn using the rotational force of the motor By absorbing and accumulating the first tension applied from the bobbin to the lead while rotating while pulling, the accumulator can supply the accumulation yarn while rotating by the needle movement regardless of the tension from the bobbin. It provides a storage active steep value which can be prevented, has a multi-dust blocking structure, has stable operation performance, and facilitates initial yarn setting.

Further still another object of the present invention is to allow the yarn to accumulate in the accumulator part continuously according to the number of turns of the correct accumulating yarn while the accumulator is being rotated, so that even if the inertial force acts during the operation of the accumulator part, We want to provide a storage active steepness that can check the number of turns.

As described above, the object of the present invention is to start and stop the operation of the motor in response to the timing of the reverse spiral motion and the spiral motion which individually perform the yarn accumulation simultaneous supply function while acting as the existing rotation wheel and the rotation belt. An internal controller for controlling; A holder part in which the internal controller is embedded; An accumulator coupled to the holder part freely rotatable and capable of braking by an electromagnet type braking device; A lead part fastened at an upper part of the accumulation part to perform a reverse spiral motion by using the motor mounted inside the accumulation part and to perform a spiral motion in accordance with a rotational direction of the accumulation part when the motor is stopped; And a sensor unit installed in the holder unit to provide a signal to the internal controller about an operating state of the lead unit, wherein the lead unit is functionally independent from the accumulation unit for the yarn-axis simultaneous feed function.

In addition, according to the present invention, the accumulation portion and the hollow fixed shaft member erected vertically based on the holder; A motor mount lower part fixed to an upper end of the fixed shaft member to seat the motor; An upper portion of the motor mount, the upper portion of the lower portion of the motor mount, the upper portion of the motor mount being rotatably disposed in contact with the rotating shaft of the motor in a non-contact manner; A nut ring portion mounted to an upper inner diameter of the hollow pillar portion; An accumulation lower part rotatably coupled to the first bearing from the fixed shaft member; An accumulating hub which is rotatably coupled to the second bearing from the hollow pillar part and interlocked with the upper part of the accumulating lower part to embed the motor, the motor mount lower part, and the motor mount upper part in an inner space; An accumulation upper portion engaged with an upper portion of the accumulation hub; It is preferable to include a plurality of accumulation pins arranged in the circumferential direction between the accumulation upper portions of the accumulation lower portion.

In addition, according to the present invention, the lead portion and the lead cap corresponding to the rotating body of the shape of closing the upper portion and the lower portion; A magnet ring mounted on an outer edge of the lead cap; A hollow guide boss extending downward from an inner center of the lead cap; And a screw shaft extended and fixed downwardly from the bottom of the upper end of the lead cap to be in contact with the inner surface of the hollow guide boss within the hollow guide boss, wherein the screw shaft is screwed with the nutring portion of the accumulator. It is preferable that the splines formed on the footnotes of the accumulating portion are slidably inserted in the rectangular spline holes of the screw shaft.

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

As shown in FIG. 1, the embodiment 10 according to the storage active yarn feeding apparatus of the present invention includes a holder portion 100, an accumulation portion 200, a lead portion 300, and a sensor portion 400.

The definition of terms to be used in the present invention are as follows.

"Fabric" refers to a thread wound on the bobbin 40 or released from the bobbin 40 to be fed or supplied toward the lead part 300.

The 'accumulated yarn' is to be understood as a yarn wound around the accumulation unit 200 or released from the accumulation unit 200 and supplied to the knitting needle 21.

"Outgoing yarn" means that the yarn of the bobbin 40 is supplied to the lead portion 300 of the present invention by the lead portion 300. At this time, the first tension that is relatively larger than the second tension, which is the sudden sudden force of the needle 21 is generated.

Accumulation of yarn absorbs the first tension while the lead part 300 reversely rotates in a direction opposite to the rotational motion of the accumulation part 200 together with a speed higher than the rotational speed of the accumulation part 200. In addition, it means to accumulate in the storage unit 200 as if the yarn is returned to the initial setting state by the amount substantially released according to the operation of the knitting needle 21 to be described below. At this time, the force that accumulates the yarn by the reverse spiral motion of the lead unit 300 is smaller than the second tension generated during the knitting needle movement does not cause cutting. The reverse spiral movement of the lead portion 300 is continuously performed even when the accumulation portion 200 is in the middle of rotation.

'Supplying the accumulation yarn' is a yarn 21 accumulated in the accumulation unit 200, that is, the accumulation yarn when the accumulation unit 200 rotates in the forward rotation direction in response to the knitting movement of the knitting needle 21. Means to loosen it and feed it. At this time, the lead part 300 performs a spiral motion in the same direction as the accumulation part 200 and does not pull the yarn from the bobbin 40 side when it returns to the original position.

The yarn accumulation simultaneous supply function periodically repeats accumulating the amount of yarn released at the same time as the 'accumulation yarn' during the normal needle movement of the knitting needle 21, such as 'accumulation of yarn'. Means.

'Reverse spiral motion' is a screw treatment relationship between the nutring part of the accumulator 200 and the screw shaft of the lead part 300, where the 'screw shaft' is lower than the rotational speed of the accumulator 200 by the operation of the motor. When the reverse rotation relatively faster, it means that the lead portion 300 is reversed and raised.

'Spiral motion' means that the lead part 300 is rotated forward and lowered in a free rotation state when the motor stops operating.

The 'cutting accident' refers to a situation in which the yarn is cut off during the 'feeding of yarn' or 'supplying accumulated yarn'.

The loosening phenomenon of the accumulation yarn is because the accumulation needle that was rotating during the operation of the knitting needle 21 of the circular knitting machine 20 or during the standby timing does not pull the accumulation yarn from the accumulation unit 200. By the inertial force of 200, a portion of the accumulation yarn of the accumulation unit 200 is loosened.

Hereinafter, the present embodiment 10 will be described in detail.

This embodiment 10 can be configured as a system together with the circular knitting machine 20 and the central control unit 30. Although not shown in FIG. 1, this embodiment 10 is mounted on a single or plural number (hundreds to hundreds) in a textile machine line (not shown), and can be connected to the central control unit 30, respectively. It is supposed to be.

This embodiment 10 is a method without a separate rotating belt or a rotating wheel for power transmission (wheel).

The holder unit 100 is arranged and installed in plural in a textile machine line (not shown), and serves to provide an installation space or a base of components.

The accumulation unit 200 and the lead unit 300 passively operate in response to the knitting needle kinetic force of the knitting needle 21 of the circular knitting machine 20 when the 'accumulating yarn' is supplied, and the knitting needle 21 is held. The shock due to the pulling second tension is absorbed by the rotation of the accumulator 200 and the helical movement of the lead part 300.

The accumulation part 200 is configured to perform free rotation based on the holder part 100. Accumulator 200 is responsible for accumulating a certain amount of yarn by the lead unit 300, or to release the yarn of the accumulator 200 corresponding to the knitting needle movement of the knitting needle 21 to supply to the knitting needle 21 side. do.

Since the accumulator 200 is passively operated with respect to the knitting needle 21, when the corresponding knitting needle 21 of the circular knitting machine 20 does not pull the accumulation yarn, the knitting needle movement force of the knitting needle 21 is no longer a tension type. Is not transmitted to the accumulation unit 200. Nevertheless, since the accumulation part 200 is coupled to the holder part 100 by using the first and second bearings, the accumulation part 200 has an inertial force to continue to rotate by the knitting needle movement force of the knitting needle 21 that has been once delivered. .

At this time, the first and second bearings prevent the shaking of the accumulator 200, and eliminate the unnecessary friction to facilitate a smooth 'supply of the accumulated yarn' when pulling the accumulation yarn in the knitting needle 21.

For this reason, the loosening phenomenon of accumulated yarn may be solved by the sensor unit 400 to be described below.

When the 'accumulated yarn' is supplied, the accumulation unit 200 rotates in the same forward rotation direction as the direction in which the knitting needle kinetic force of the knitting needle 21 is applied.

The first, second, third, and fourth yarns 412, 112, 313, 314, and 絲路 have a ceramic material to guide the passage of the yarn.

The first repulsive magnet 340 is preferably formed in the center of the upper end of the lead portion 300. More preferably, the first repulsive magnet 340 is installed in the center of the upper end of the lead cap 310 corresponding to the lead portion 300. The second repulsive magnet 114 corresponding thereto is installed around the second apostle 112. The second slope 112 is formed at an upper end of the lead portion 300 as an end of the upper protrusion 110 of the holder portion 100.

The upper protrusion 110 is preferably a structure extending inclined from the holder portion 100 to the vertical upward space of the lead portion 300.

Since the first repulsive magnet 340 and the second repulsive magnet 114 have the same polarity and are arranged to exert mutual repulsive force, the reed force 300 acts as a result of the repulsive force acting close to each other. It plays the role of a non-contact stopper to stop the reverse spiral motion of the helical motion, and also induces a switch to the spiral motion after the stop of the reverse spiral motion.

The sensor unit 400 includes first and third sudden death detection sensors 410 and 440 for cutting off; The second sudden detection sensor 430 for preventing loosening by the inertial force mentioned above; A stroke sensor (420) for checking a lead distance for maintaining the number of windings of the accumulation yarn; A micom type internal controller 450 for controlling the start and stop of the operation of the motor in response to the timing of the reverse spiral motion and the spiral motion of the lead part 300; A power on / off switch 460 is provided to engage in normal operation.

The circular knitting machine 20 operates the knitting needles 21 for knitting of the fabric so that the knitting needles move up and down, and operate in correspondence with a predetermined sudden feeding condition. The knitting needle 21 of the corresponding standard installed in the circular knitting machine 20 pulls the accumulation yarn from the accumulation unit 200 of the present embodiment 10. In this case, in response to the generated tension, the accumulator 200 rotates, or the lead unit 300 spirals along with the accumulator 200.

The central control unit 30 is composed of a well-known detection system that can detect whether or not to stop the supply of the accumulation yarn. At this time, the internal controller 450 is configured to detect the cutting of the yarn or accumulated yarn, and transmit the result to the central control unit (30).

That is, the central control unit 30 or the internal controller 450 may be connected to the first, second, and third sudden death sensor 410, 430, 440. Here, the first, second, and third yarn detection sensors 410, 430, and 440 are combined with the first, second, and third triggers 411, 431, and 441 to cut yarns or accumulation yarns. The rotations o1 and o3 of the corresponding first and third triggers 411 and 441 or the rotation o2 of the second trigger 431 corresponding to the deflection of the accumulation yarn are respectively sensed.

For example, the first trigger 411 has a magnetizing force by the permanent magnet placed therein. The first slope 412 is formed at one end of the first trigger 411. In addition, the other end of the first trigger 411 is rotatably coupled to the upper protrusion 110 of the holder portion 100 (o1).

At this time, the feed yarn supplied from the upper side of the present embodiment 10 from the bobbin 40 is set to pass through the first slope 412 toward the tension regulator 119 of the upper projection 110.

Accordingly, when the first trigger 411 is supported by the yarn and stands slightly inclined, and the cutting occurs due to excessive external force or other causes, the first trigger 411 rotates within a finite arc angle range by gravity. 11A and 11B, the contact ends are in contact with the upper protrusion 110.

According to the contact, the first sudden detection sensor 410 such as a leader switch detects the magnetization force of the first trigger 411 as a contact signal.

The corresponding contact signal is transmitted from the first sudden detection sensor 410 to the central control unit 30, and the central control unit 30 corresponds to a predetermined operation control algorithm whether the circular knitting machine 20 is operated or stopped. Or generate a maintenance signal.

In addition, during operation stop or standby of the needle needle 21, the sudden death is released from the accumulation unit 200 subjected to the inertia force, 'unwinding phenomenon of the accumulation cloud' occurs, and the center of the sudden death of the sudden drop occurs. By this 'slack sag', the second trigger 431 is rotated (o2) within a finite arc angle range downward.

At this time, similar to the operation principle of the leader switch, the second sudden detection sensor 430 detects the rotation o2 of the second trigger 431. The corresponding detection signal is transmitted from the second sudden detection sensor 430 to the internal controller 450. In this case, the internal controller 450 is connected to the electrostatic braking device of the electromagnet type, and prevents the loosening phenomenon of the accumulation yarn by rapidly braking the rotation of the accumulation unit 200 by the inertial force.

In addition, the third trigger 441 is supported by the yarn during the knitting needle movement of the knitting needle 21, when the cutting occurs, it rotates (o3) within a finite arc angle range by gravity.

At this time, similar to the operation principle of the leader switch, the third reduced limb sensor 440 detects the rotation o3 of the second trigger 431. The corresponding detection signal is transmitted from the third sudden detection sensor 440 to the central control unit 30 or to the internal controller 450. By using the detection signal, the same as the first detection yarn sensor 410 described above, the determination of the operation or stop of the circular knitting machine or the generation of a maintenance signal is made.

As described above, the internal controller 450 serves to prevent the loosening phenomenon of the accumulation yarn, and to prevent the 'cutting off accident'.

To this end, the internal controller 450 further includes a current value detection module (not shown) that detects or checks a change in the current value supplied to the motor for the rotation of the motor installed in the accumulation unit 200.

The internal controller 450 checks the change of the current value with a preset reference value (for example, 20 amps) using the current value detection module during supply of the accumulation yarn. As a result, the internal controller 450 that detects more than the reference value may determine that the tension or more than the allowable tension is applied to the sudden death.

According to the result of the determination, the internal controller 450 is controlled by the known electronic circuit technology to perform overall control on the operation of the motor, such as interrupting or resuming the power supplied to the motor, or maintaining a proper torque force. Consists of.

In addition, the internal controller 450 has a function of preventing a malfunction caused by the accumulation unit 200 to continue to rotate by the inertial force when the sudden stop. To this end, the internal controller 450 is configured by a known electronic circuit technology so as to suddenly brake the rotation of the accumulator 200 by activating the electromagnet type sudden braking device at the same time as the circular knitting machine sudden stop.

The internal controller 450 is connected to the central control unit 30 through the power on / off switch 460, thereby allowing the user to selectively use the present embodiment 10 as needed.

The internal controller 450 is manufactured by a well-known electronic circuit technology to perform general electronic control functions necessary for the detailed operation descriptions below, such as involved in operation of the motor (motor power supply) and stop (motor power off). It is.

Hereinafter, the coupling relationship of the present embodiment 10 will be described.

At this time, the first and second braking plates 120 and 123 are made of a non-conductive material, so that the magnetic force of the electromagnet coil 122 corresponding to the electromagnet is minimized.

On the other hand, the plurality of braking rings 124 and the bushing 121 of the upper portion of the second braking plate 123 is made of a conductive material, respectively, and used as a movement path of the magnetization force generated in the electromagnet coil 122 do.

An ellipse hole 126 of each braking ring 124 is inserted into each elliptic protrusion 125 so as to slide up and down but not rotate.

As shown in FIG. 2, the accumulation part 200 includes an accumulation lower part 210, a hollow fixed shaft member 220, a motor mount lower part 230, an accumulation pin 240, a motor 250, and a footnote 260. ), The motor mount upper portion 270, the accumulation hub 280, and the accumulation upper portion 290 are sequentially coupled, and their coupling state is clearly identified in FIG. 10.

In addition, the lead unit 300 includes a lead cap 310, a magnet ring 320, a screw shaft 330, a first repulsive magnet 340, and a pin-shaped second stopper 350.

First, the accumulation lower portion 210 has a skirt shape so that the lower ends of the plurality of accumulation pins 240 to be described below can be inserted and circularly arranged.

The accumulation lower portion 210 forms a circular space 211 that surrounds the motor mount lower portion 230 in a non-contact manner within the skirt shape. The first bearing 212 is installed on the bottom surface of the circular space 211. The accumulation lower portion 210 is rotatably coupled to the fixed shaft member 220 by the first bearing 212.

The fixed shaft member 220 fixes one end (upper end) of the fixed shaft member to the bottom surface of the lower motor mount 230. The other end (lower end) of the fixed shaft member 220 passes through the first bearing 212 and the bushing 121 of the accumulation lower portion 210, and then fixes the washer 221 at the center hole 105 of the holder portion 100. ) And nuts 222.

Accordingly, the motor mount lower portion 230, the housing of the motor 250, and the motor mount upper portion 270 associated with the fixed shaft member 220 may be fixed based on the holder portion 100.

The motor mount lower portion 230 forms a circular wall on the outer side of the circular bottom surface to seat the housing of the motor 250 therein. A fitting portion is formed at the upper end of the circular wall of the motor mount lower portion 230.

The accumulation pin 240 is inserted into each of the plurality of lower pin holes 213 of the accumulation lower portion 210 having a skirt shape. The plurality of lower pin holes 213 are arranged while maintaining a predetermined interval in the circumferential direction at the skirt-shaped portion of the accumulation lower portion 210 to form a drum shape.

In particular, the inclined top portion 244 is a place included in the main range of motion of the lid portion. As the yarn wound around the inclined top portion 244 is accumulated constantly as the bottom of the inclined top portion 244 is pushed down, the overlap of the yarn due to the reverse spiral motion of the lead portion 300 is prevented.

As shown in FIG. 2, the motor 250 is controlled by an internal controller 450. For example, the motor 250 may be a small DC motor or a servo motor in the present invention. In addition, the internal controller 450 controls the rotation axis of the motor 250 to be freely rotated by maintaining the motor 250 in an operation stop state when the 'accumulated yarn' is supplied, and the motor 250 when the 'accumulated yarn' is accumulated. ) To rotate in the reverse direction.

To this end, the connecting wire of the motor 250 extends along the hollow of the fixed shaft member 220 and is then electrically connected to the internal controller 450.

The housing of the motor 250 is fixed inside the motor mount upper part 270 and the motor mount lower part 230 while being wrapped by the motor mount upper part 270 and the motor mount lower part 230. On the other hand, the rotation axis of the motor 250 is axially coupled to rotate the footnote 260.

FIG. 5 is a bottom view of the footnote shown in FIG. 2. FIG. The footnote 260 integrally forms a circular hollow shaft portion 261 and a rectangular spline 262.

As shown in FIG. 2, the lower end of the circular hollow shaft portion 261 is axially coupled to the rotating shaft of the motor 250, and the upper end of the circular hollow shaft portion 261 forms a rectangular spline 262.

The rectangular spline 262 is responsible for transferring the reverse rotational power of the motor 260 to the screw shaft 330 of the lead unit 300.

The motor mount upper portion 270 includes a large diameter portion 271 having a relatively large diameter so as to be fitted to the motor mount lower portion 230; The hollow pillar portion 272 is erected through the center of the large diameter portion 271.

Here, a plurality of dowels 273 and dowels are formed on the upper inner surface of the large-diameter portion 271. Each dowel 273 protrudes downward, and can be inserted into a plurality of dowel holes formed in the upper surface of the housing of the motor 250.

The hollow column 272 is a kind of spindle. The internal structure of the hollow pillar portion 272 is formed to surround the footnote 260 in a non-contact manner. The outer structure of the hollow pillar portion 272 is the direct rotation support base of the accumulation hub 280, or indirect rotation support base of the accumulation lower portion 210, the accumulation pin 240, the accumulation upper portion 290.

In addition, a nut ring portion 274 is attached to the upper inner diameter of the hollow pillar portion 272. The nut ring portion 274 has a female screw in a screw pair relationship with the male screw of the screw shaft 330 of the lead portion 300.

At this time, the nut ring portion 274 is fixed at the upper end of the hollow pillar portion 272.

On the other hand, the screw shaft 330 is screwed with the nut ring 274. The screw shaft 330 forms the rectangular spline hole 331 to extend along an axial direction. The spline 262 of the footnote 260 is slidably inserted into the rectangular spline hole 331 of the screw shaft 330.

The pin-shaped first stopper 275 protrudes upward from the upper end of the hollow pillar portion 272 around the nut ring portion 274. As the first stopper 275 performs the same role as the stop jaw in response to the second stopper 350, the lead cap 310 performs an excessive reverse spiral movement to prevent the first capper 275 from falling below the initial setting position. In charge.

The accumulation hub 280 is provided with a second bearing 281 therein.

Referring to FIG. 6, the accumulation hub 280 mounts the second bearing 281 using the internal boss 284 of the accumulation hub 280 to be rotatable with a known spindle based on the hollow pillar portion 272. Doing. In addition, the accumulation hub 280 has a plurality of accumulation pin guide holes 282 formed on the outer circumferential surface of the circular tube shape in accordance with the arrangement number and spacing of the accumulation pin 240 of FIG. 2.

In addition, as shown in FIG. 2, the accumulating hub 280 further has a fitting projection groove 283 at the upper edge thereof, so that the accumulating hub 280 is easily coupled with the accumulating upper portion 290.

The accumulation upper portion 290 has a shape such as a hat of a circular awning that is opened up and down.

FIG. 7 is a bottom view of the accumulation upper portion 290 shown in FIG. 2. The accumulation upper portion 290 includes a first bushing bearing 291 having a multi-dust blocking structure provided on an inner surface of its central boss; An insertion groove 292 for the accumulation hub 280 formed on the bottom of the accumulation upper portion 290; It is arranged around the insertion groove 292 and includes a plurality of upper pin holes (293) for inserting the pin upper end of the accumulation pin.

Particularly, the insertion groove 292 is formed with a fitting protrusion 294 for fastening to the fitting protrusion groove 283 of the accumulation hub 280 of FIG. 2.

The lead cap 310 corresponds to a rotating body having a top closed and a bottom opened. The lead cap 310 has a magnet ring 320 attached to the outer edge. The magnet ring 320 is sensed by the stroke sensor 420, to detect the number of turns of the accumulation yarn to be described later, or the stroke of the reverse spiral or spiral motion made between the top dead center position and the bottom dead center position. Is used to check

For example, the stroke sensor 420 inputs a detection signal that checks the stroke distance of about 25 mm to the internal controller 450, but the internal controller 450 uses the input signal corresponding to the stroke distance, and accumulates the accumulation unit. Detects the number of windings of the accumulated yarn wound on (200). This is because the number of windings of the accumulated yarn corresponding to the stroke length is recorded in advance by the experiment in the internal controller 450.

FIG. 8 is a plan view of the magnet ring 320 shown in FIG. 2. The magnet ring 320 may include a ring portion 321 such as a ring shape or an English letter 'C' having one side open; The ring part 321 includes a plurality of permanent magnets 322 (for example, three) arranged to maintain an array angle of 120 °.

Referring to FIGS. 9 and 2, which are bottom views of the lead cap 310, a ring portion coupling groove 311 is formed at an outer edge of the lead cap 310 to correspond to an arrangement angle of the permanent magnet 322. Magnet coupling groove 312 is formed.

A third slope 313 is formed at an upper corner of the lead cap 310. As the third slope 313 is formed to pass the inclination angle to the outside of the lead cap 310, it can prevent the twist of the yarn during the reverse spiral or spiral movement of the lead cap 310.

In addition, a fourth slope 314 is formed at a part of the outer edge of the lead cap 310 in the vertical downward direction of the third slope 313.

A hollow guide boss 315 extending downward is formed at the inner center of the lead cap 310.

A second bushing bearing 316 having a multi-dust blocking structure is formed at the lower inner diameter of the hollow guide boss 315.

The screw shaft 330 is in contact with the inner surface of the hollow guide boss 315 inside the hollow guide boss 315, but is fixed to extend downward from the bottom of the upper end of the lead cap 310.

In particular, the first repulsive magnet 340 is installed in the center of the upper end of the lead cap 310 with respect to the upper portion of the screw shaft 330.

The second stopper 350 is formed to protrude from the center of the upper end of the lead cap 310 toward the first stopper 275.

As shown in FIG. 10, the multi-dust blocking structure is used in combination with preventing friction, and corresponds to an airtight gap 319 between the outer diameter of the accumulation upper portion 290 and the inner diameter of the lead cap 310. Primary structure; A secondary structure corresponding to the first bushing bearing 291 located between the hollow pillar portion 272 of the motor mount upper portion 270 and the central boss of the accumulation upper portion 290; The air flow path includes a tertiary structure corresponding to the second bushing bearing 316 positioned between the hollow guide boss 315 of the lead cap 310 and the hollow pillar portion 272 of the upper portion of the motor mount 270. (d) Blocks the dust in multiple stages and at the same time facilitates the smooth rotation of the lead portion (300).

The accumulation upper portion 290 is coupled to the upper portion of the accumulation hub 280, and the accumulation lower portion 210 is coupled to the lower portion of the accumulation hub 280. At this time, the lower pin portion 241 of each of the accumulation pin 240 is in the lower pin hole 213 of the accumulation lower portion 210, the center portion 243 of the accumulation pin 240 in the accumulation pin guide hole 282, The pin top end 245 of the accumulation pin 240 is coupled to the upper pin hole 293 of the accumulation upper part 290, respectively.

The housing of the motor 250 is fixed inside the motor mount upper portion 270 and the motor mount lower portion 230. The motor 250 rotates its rotating shaft and the footnote 260 in reverse spiral motion, and can be freely rotated in spiral motion.

In this case, the motor 250 may provide the footnote 260 with a reverse rotational power capable of reverse helical movement of the lead part 300 relatively faster than the rotational speed at which the accumulation part 200 rotates by the needle.

 The spline 262 of the footnote 260 is slidably inserted in the rectangular spline hole 331 of the screw shaft 330.

Thereafter, the reverse rotational power of the motor 250 is transmitted to the screw shaft 330 through the spline 262 and the rectangular spline hole 331 of the footnote 260, and lifts the screw shaft 330 and the lead cap 310. Allows you to reverse the spiral in the up direction.

In contrast, when the motor 250 is stopped, the reverse rotational power is not transmitted to the spline 262 of the footnote 260, and the motor 250 is in a free rotation state.

In addition, tension is applied to the yarn to be supplied from the upper side of the lead portion 300 by the usual yarn setting equipment installed at the time of yarn supply, not shown, including the tension regulator 119.

Further, the lead portion 300 is caused by the eccentric arrangement of the third and fourth slopes 313 and 314 and the tension held by the accumulation yarn wound between the accumulation portion 200 and the lid portion 300. The situation is made to accompany the accumulation unit 200.

In this case, when the knitting needle pulls the accumulation yarn of the accumulation unit 200, the spiral movement of the lead unit 300 may be simultaneously performed along with the rotational movement of the accumulation unit 200.

11A and 11B are cross-sectional views illustrating an operation relationship of the first trigger 411.

11A and 11B, the first trigger 411 is made of a magnetizable conductive material and is bent to have a link shape. A permanent magnet 413 is disposed between one end of the first trigger 411 and the first apostle 412 to magnetize the first trigger 411 itself. The other end of the first trigger 411 is rotatably coupled to the upper protrusion 110 of the holder part 100.

The first trigger 411 is supported by the yarn and stands slightly inclined, and when truncation occurs, it rotates (o1) within a finite arc angle range by gravity and contacts the contact end 414.

The contact end 414 is connected to the first sudden death sensor 410 through an internal connection wire of the upper protrusion 110.

The first sudden detection sensor 410 transmits a contact signal sensed through the contact end 414 to the central control unit 30, thereby allowing the central control unit 30 to advance the operation or stop of the circular knitting machine 20. Decision corresponding to the operation control algorithm specified in the or to generate a maintenance signal.

At this time, the tension regulator 119 is configured to variably act by using the lever in the direction in which the pair of pressing plate is in close contact with the spring, installed there, when passing the yarn between the pressing plate, It is preferable to hold the yarn while giving the yarn a tension of a predetermined size.

Therefore, even if a 'cut off accident' occurs, the yarn supplied toward the lead portion 300 is not separated from the second yarn 112, and maintenance such as having to reconnect the yarn is very convenient.

12A and 12B are enlarged cross-sectional views of the circle M of FIG. 10 to explain a braking method of the accumulator 200.

Here, when the internal controller determines that it is necessary to stop the rotation of the accumulator 200 by using various signals input from the sensor unit, the internal controller applies power to the electromagnet coil 122 and the electromagnet coil 122. Magnetize it like an electromagnet. First and second braking plates 120 and 123 are stacked on upper and lower portions of the electromagnet coil 122.

In this case, the first and second braking plates 120 and 123 are weak magnetic materials that are relatively non-magnetic material (e) as a non-conductive material. Therefore, the magnetization force e generated by the electromagnet coil 122 is transmitted to the first bearing 212 using the bushing 121 which is a conductor material as a moving path. As a result, all of the inner ring, the ball, and the outer ring which are the components of the first bearing 212 are magnetized by the magnetizing force e. At this time, since the first gap d1 between the braking ring 124 and the first bearing 212 is smaller than the second gap d2 between the braking ring 124 and the bushing 121, a relatively large magnetization force is braked. It acts between the ring 124 and the first bearing 212.

As a result, the braking ring 124 is attached to the first bearing 212 while the magnetizing force (e) is acting to generate a braking force, and when the magnetizing force (e) is not applied by the internal controller, the first bearing ( 212). The method of returning the braking ring 124 to either the gravity method or the spring method may be used in the present invention, and if necessary, move the installation position of the brake ring 124 to the lower side of the lower motor mount 230. Of course it can.

On the other hand, since the elliptical hole 126 of the braking ring 124 is inserted into the elliptic protrusion 125 of the second braking plate 123, the braking ring 124 itself is rotated or the first bearing 212 is rotated. Slip hardly occurs between and, resulting in reliable braking performance.

In addition, due to such an operation relationship, the material of the accumulation lower portion 210 itself may be made of a material such as plastic, not iron or a conductor, and the manufacturing of the accumulation lower portion 210 may be facilitated.

13A to 13C are cross-sectional views illustrating a method of operating a storage active feeding device. Here, reference numeral 'I' is an initial setting position, 'L' is a bottom dead center position, and 'U' is a top dead center position. In addition, reference numeral 'S' is an administrative distance between 'L' and 'U' according to the reverse spiral motion or spiral motion, and 'B' means the basic yarn accumulation distance.

A process of initially supplying and setting yarns to the lead unit 300 will be described with reference to FIGS. 13A and 13B.

The lead portion 300 is located at the initial setting position I below the bottom dead center position L. FIG.

Then, the yarn is extended downward from the bobbin and the first slope (not shown) using a well-known yarn fitting mechanism, passing through the tension regulator 119 and the second slope 112, the third slope of the lead portion 300 ( After extending obliquely toward 313, after passing through the fourth slope 314 in the vertical direction, it is set to be connected to a knitting needle (not shown).

In this state, power is supplied to the internal controller in this embodiment, and the initial yarn supply signal is received from the central control unit according to a well-known yarn supply algorithm predefined in advance.

In response to the original yarn feed signal, the internal controller performs the initial setting of the yarn. That is, the internal controller operates the motor 250, and thus the motor 250 rotates the rotary shaft and the footnote 260 in the reverse rotation direction.

The reverse rotational power of the footnote 260 is transmitted to the screw shaft 330 of the lead unit 300 through the spline and the spline hole as described above.

Accordingly, the screw shaft 330 starts the reverse helix movement in the nutring portion 274 that is threaded, and eventually causes the entire lead portion 300 to reverse the helix movement f1.

The reverse spiral motion f1 of the lead part 300 is wound from the initial setting position (I) to the top dead center position (U) through the bottom dead center position (L), and the yarn is wound around the accumulation unit (200). In position U, the motor 250 stops according to an operation stop and mutual repulsive action of the first repulsive magnet 340 and the second repulsive magnet 114. Here, the operation stop of the motor 250 is realized by the stroke sensor 420, the magnet ring 320 and the internal controller described above.

Since the process of the motor 250 is performed in about 1 second of actual operation, the initial setting process of the yarn, which previously took about 1 hour to initially set the yarn, is processed in a very short time (for example, 1 second). can do.

As shown in FIG. 13B, the first repulsive magnet 340 and the second repulsive magnet 114 act as mutual repulsive forces in a close state, thereby serving as a non-contact stopper at the top dead center position U and the reverse spiral motion ( After the stop of f1) serves to induce a switch to the spiral motion (f2).

Thereafter, the central control unit starts the operation of the circular knitting machine. The needle supply of the circular knitting machine is performed by the aforementioned 'supply of yarn'.

As described in detail in 'Supply Yarn', the accumulator 200 rotates in the forward rotation direction (for example, counterclockwise), and at the same time, the lead portion is formed by the screw shaft 330 and the nutring portion 274. (300) also performs a spiral motion f2 from the top dead center position (U) to the bottom dead center position (L). In this case, the accumulation yarn is supplied toward the knitting needle while being released with the rotation of the accumulation unit 200.

According to the rotation of the motor 250, the rotational force (eg, reverse spiral motion) is provided to the lead part 300, and accordingly, the yarn toward the bobbin 40 (see FIG. 1) is pulled, and thus the tension from the bobbin is It is absorbed and accumulated by the reverse spiral motion of the lead portion 300.

Thus, since the yarn is accumulated in the accumulator 200, the accumulator 200 itself becomes free from the tension applied from the bobbin, so that the accumulating yarn of the accumulator 200 can be supplied to the knitting needle in the best state.

In addition, the stroke sensor 420 detects the magnet ring 320 descending from the top dead center position (U) to the bottom dead center position (L) and checks the amount of the accumulated yarn released from the accumulation unit (200). .

As shown in FIG. 13C, the internal controller resumes the operation of the motor 250 when the bottom dead center position L of the lid part 300 is detected in the same sensing manner.

By the resumption of the motor 250, the lead unit 300 again performs the reverse spiral motion f3 at a speed faster than the forward rotation speed of the accumulation unit 200, thereby resetting the amount of the accumulated accumulated yarn again. Rewind repeatedly so that it accumulates to its original state.

13B and 13C described above are repeated to supply the accumulation yarn of the accumulation unit 200 to the circular knitting machine. In addition, when the external force is applied to the yarn supplied from the upper side of the lead portion 300 or more than the allowable tension, for example, when the user grabs the supplied yarn by hand, at this time, the existing product is broken yarn, this embodiment For example, by checking the amount of current supplied to the motor 250 before the yarn is cut off, the operation of the circular knitting machine is stopped, and then the power of the motor 250 is cut off. Then, when the obstacle is eliminated, the present embodiment again performs sudden death and accumulation.

As described above, according to the present invention configured as described above, as the yarn accumulation simultaneous supply function is performed by a separate lead unit configured to be functionally independent from the accumulator unit, the lead unit pulls the yarn with the rotational force of the motor and comes from the bobbin. The advantage of providing a storage active steep spin that can absorb and accumulate tension and supply the accumulation yarn by rotating only by the needle movement regardless of the tension coming from the bobbin, so that the accumulation and accumulation yarn can be smoothly supplied. There is this.

In addition, since the storage active steepness of the present invention has a coupling structure between the lead portion and the accumulation portion as described above instead of the conventional rotating belt or the rotating wheel, it is possible to perform a functionally independent 'axial axis simultaneous supply function' There is an advantage to this.

The storage active steepness device according to the present invention measures the number of windings of the accumulated yarn during the reverse spiral motion and the spiral motion of the lead portion, and accumulates the yarn repeatedly precisely and precisely as quickly and accurately as the amount of the accumulated yarn released from the accumulation part. There is an advantage to accumulate.

The storage active steepness of the present invention has the advantage of preventing the cutting in advance by the realization of tension absorption and motor control, and has the advantage of easy initial setting of the yarn.

In addition, the storage active steeping device of the present invention is a type that does not have a rotation belt can actively respond to the diversification of the rapid feeding speed, there is an advantage that can replace all of the previously mentioned steep spin.

In addition, the storage active steeping device of the present invention has a multi-dust blocking structure to prevent the inflow of wind surface, dust, etc. generated during the sudden injection into the inside of the device, to ensure a high efficiency operating performance There is an advantage.

In addition, the storage active steeping device of the present invention is provided with an electromagnet type braking device, and when the circular knitting machine is stopped or the yarn supply is stopped, the braking of the accumulation portion acting inertial force is prevented to prevent sagging of the accumulation yarn. There are advantages to it.

In addition, since the storage active steep spiner of the present invention operates the motor only when accumulating the yarn in the accumulating part, a separate motor power is not consumed at the time of supplying the accumulating yarn, and thus there is a very efficient advantage in the amount of electricity used.
