Detailed Description

Hereinafter, a yarn processing apparatus according to the present invention will be described with reference to the drawings.

As shown in fig. 1 to 10, the yarn processing apparatus according to the present invention includes, as a yarn processing apparatus for winding a yarn W supplied from a yarn supply unit 100 around a winding bobbin 10: a yarn supplying section 100 for supplying the yarn W to the winding bobbin 10; a winding part 200 to which the winding shaft 10 is attached and which rotates the winding shaft 10 to wind the yarn W supplied from the yarn supplying part 100; and a thread cutting unit 300 for cutting the thread W supplied from the thread supply unit 100.

Here, the winding bobbin 10, as a structure for winding a wire such as a welding wire, is provided for winding the wire W supplied from the wire supply portion 100, and may have various structures.

For example, the winding reel 10 may include: a shaft portion 11 formed in a cylindrical shape and around the outer peripheral surface of which a yarn W is wound; the pair of flange portions 12 are formed at both ends of the shaft body portion 11 in the longitudinal direction to prevent the yarn W wound around the shaft body portion 11 from falling off.

The shaft portion 11 is configured to facilitate winding of the yarn W around the winding shaft 10, and may have various shapes and materials.

For example, it is preferable that the outer circumferential surface of the shaft portion 11 is formed with a protrusion portion to a groove portion for winding the yarn W, and has a hollow type cylinder structure to be combined with a rotation portion (not shown) described later.

In this case, the shaft portion 11 may be provided with or coupled to a starting end of the wire W wound around the winding shaft 10. Specifically, the shaft portion 11 may have a tool for fixing the tip end of the completed wound wire W, and the tool may have various structures, for example, a hole 13 formed to insert the tip end of the wire W, etc., and the material may be various materials such as plastic, etc.

The pair of flange portions 12 may be provided at both ends in the longitudinal direction of the shaft body portion 11 to prevent the yarn W wound around the shaft body portion 11 from falling off.

At this time, the tool 13 for fixing the leading end or the trailing end of the wire W may be formed in the flange portion 12 instead of the shaft portion 11.

The yarn supplying section 100 serves as a device for supplying the yarn W to the winding bobbin 10

The structure of (3) may be variously structured.

For example, the thread supplying part 100 may include: a large bobbin 110 on which a large amount of the wire W is wound; a rotating device (not shown) for rotating the large bobbin 110.

The winding unit 200 is provided to rotate the winding shaft 10 to wind the yarn W supplied from the yarn supplying unit 100, and may have various configurations.

For example, the winding part 100 may include: a rotating shaft (not shown) inserted in the center of the winding bobbin 10 in the length direction; a rotation driving part (not shown) that rotates a rotation shaft (not shown).

Then, the winding part 200 may have a structure for mounting or separating the winding shaft 10, in addition to the structure for rotating the winding shaft 10.

As shown in fig. 1, a yarn tension adjusting unit 800 may be further provided between the yarn supplying unit 100 and the winding unit 200, and the yarn tension adjusting unit 800 adjusts the tension of the wound yarn W to wind the yarn W with uniform tension.

On the other hand, it is preferable that the winding bobbin 10 is automatically supplied to the winding portion 200 and automatically discharged to the outside after the winding of the yarn W is completed.

Accordingly, as shown in fig. 1, the thread processing apparatus may further include: a bobbin loading part 500 for loading a winding bobbin 10 of the yarn W to be wound; a bobbin conveying part 600 that conveys the winding shaft 10 from the bobbin loading part 500 to the winding part 200; the bobbin discharging part 700 that receives the winding bobbin 10, which has completed winding, from the winding part 200 and discharges the same to the outside.

The bobbin loading portion 500 is configured to load the winding bobbin 10 on which the yarn W to be wound, and is configured to transmit the winding bobbin 10 received from the outside to the bobbin conveying portion 600 by at least one of linear movement and rotational movement, and various configurations are possible according to the movement method.

The bobbin conveying portion 600 is configured to convey the winding shaft 10 from the bobbin loading portion 500 to the winding portion 200, and may have various configurations.

The bobbin conveying portion 600 may be configured to convey the winding bobbin 10 in order to remove the wound winding bobbin 10 to the outside.

For example, the bobbin transfer part 600 may include an articulated robot (not shown) that holds winding bobbins 10 sequentially supplied from the bobbin loading part 500 to be transferred to the winding part 200 along a three-dimensional trajectory.

In the case where the bobbin transfer part 600 is configured by a multi-joint robot, a compact and simple structure for transferring the winding shaft 10 can be realized, and there is an advantage that the winding shaft 10 can be transferred quickly.

The bobbin discharging part 700 is a structure for receiving the winding bobbin 10 wound by the winding part 200 and discharging it to the outside, and may have various structures.

The transportation of the winding bobbin 10 from the winding portion 200 to the bobbin discharging portion 700 may also be performed by the above-described articulated robot, but the winding bobbin 10 completing the winding is greatly increased in weight due to the wire W, and thus the transportation is preferably performed by another conveying line, such as a conveyor belt (not shown) or an elevator.

In addition, a label attaching portion (not shown) for attaching a label for factory-finished winding of the bobbin 10 may be further provided at the bobbin discharging portion 700.

The yarn cutting unit 300 is configured to cut the yarn W supplied from the yarn supplying unit 100 to the winding bobbin 10, and may have various configurations.

As shown in fig. 1, the thread cutting part 300 may be disposed between the planar thread supplying part 100 and the winding part 200.

As shown in fig. 1 and 4 to 7, the wire cutting part 300 may include a pair of cutters 312 and 314 to cut the wire W introduced between the pair of cutters 312 and 314.

As shown in fig. 5a to 5d, the pair of cutters 312 and 314 are preferably arranged in the longitudinal direction (X-axis direction) of the winding bobbin 10 wound in a planar shape.

The pair of cutters 312 and 314 are structures that cross each other in front and rear to cut the wire W that enters between the pair of cutters 312 and 314, and may have various shapes and materials.

For example, the pair of cutters 312 and 314 may form blades (blades) on sides corresponding to the wire W, and may be formed of a metal material for rigidity.

Both the pair of cutters 312, 314 are movably disposed, or one of the pair of cutters 312, 314 is in a fixed state and the other is movably disposed.

However, in order to stably cut the wire W by the pair of cutters 312, 314, it is necessary to fix the movement generated due to the shaking, vibration, or the like of the wire W.

Accordingly, the yarn processing apparatus of the present invention may further include a yarn fixing unit 350, and the yarn fixing unit 350 may fix the yarn W to the winding unit 200 with reference to a position where the pair of cutters 312 and 314 cut the yarn W.

As shown in fig. 5a to 5d, the wire fixing part 350 may be constituted by a gripper provided between a pair of cutters 312 and 314 and the winding bobbin 10, but is not limited thereto.

The wire fixing unit 350 is movably disposed in at least one of an X-axis direction, a Y-axis direction, a Z-axis direction, and a Θ -axis direction, and thus moves to the winding bobbin 10 while clamping the cut wire W, and the end of the wire W is inserted into the hole 13 of the winding bobbin 10, thereby finally completing the winding process of the winding bobbin 10.

In addition, in order to prevent the yarn W, which was once supplied from the yarn supply unit 100 when the yarn W was cut by the pair of cutters 312 and 314, from retreating to the yarn supply unit 100 side due to elasticity, a tool for fixing the yarn supply unit 100 needs to be added to the yarn supply unit 100 based on the cutting position of the yarn W.

Accordingly, the yarn processing apparatus of the present invention may further include a yarn retreat preventing tool 900, and the yarn retreat preventing tool 900 may supply the yarn W to the yarn supply portion 100 side with reference to a position where the pair of cutters 312 and 314 cut the yarn W.

The yarn retreat preventing tool 900 may have various configurations as long as it moves to a position where it does not interfere with the yarn W when winding the yarn W and presses the side surface of the yarn W to fix the yarn W when cutting the yarn W so as not to retreat the yarn W to the yarn supply portion 100 again.

For example, the wire retreat preventing means 900 may include a pair of rollers (not shown) that rotate about a rotation axis perpendicular to the moving direction of the wire W (Y-axis direction with reference to the drawing) when winding, and between which the wire W is placed and which face each other.

In addition, the wire retreat preventing means 900 may include a roller interval adjusting means for adjusting an interval between the pair of rollers to change the interval between the pair of rollers when winding and cutting the wire.

The outer side surfaces of the pair of rollers may be formed with projections and depressions or grooves matched with the yarn, thereby more effectively fixing the pressurized yarn W.

When the cutting of the yarn W is completed by the pair of cutters 312 and 314, the ends of the yarn W fixed to the pair of rollers move toward the winding unit 200, are fixed to the replaced empty bobbin 10, and the winding process can be performed again.

The movement of the end of the wire W fixed to the pair of rollers toward the winding portion 200 side can be achieved by various tools. For example, the pair of rollers may rotate to move the end of the wire W toward the winding part 200, but this is merely an embodiment and the scope of the present invention is not limited thereto.

On the other hand, the thread cutting section 300 cuts the thread W entered between the pair of cutters 312, 314, and therefore it is necessary to prevent interference between the thread W and the thread cutting section 300 during winding.

Accordingly, as shown in fig. 2a to 4, the yarn cutting section 300 of the present invention may be vertically moved so as not to interfere with the winding of the yarn W by the winding bobbin 10.

That is, the thread cutting unit 300 is in a standby state in which it is moved downward so as not to interfere with the thread W while the thread W is being wound around the bobbin 10, and when the thread W needs to be cut after the winding of the bobbin 10 is completed, the thread cutting unit 300 is moved upward so as to cut the thread between the pair of cutters 312 and 314.

As shown in fig. 2c, if the cutting of the yarn W is completed, the yarn cutting unit 300 moves downward again to wind the yarn W on the next winding shaft 10.

The up and down movement of the wire cutting part 300 may be accomplished in various ways and structures, of course.

For example, as shown in fig. 4, the wire cutting part 300 may include: a base part 320 provided with at least one of the wire cutting parts 300; an upper and lower guide part 330 which is coupled to the base part 320 to be movable downward; and an up-and-down driving part (not shown) for driving the base part 320 to move along the up-and-down guide part 330.

The base portion 320 is configured to be movable up and down and to provide at least one of the pair of cutters 312 and 314, and preferably, the pair of cutters 312 and 314, and may have various shapes and materials.

The base portion 320 may form an installation surface on which the pair of cutters 312 and 314 and the wire winding portion 400 described later are installed.

Specifically, when one of the pair of cutters 312, 314 is referred to as a first cutter 312 and the other is referred to as a second cutter 314, the first cutter 312 may be fixedly disposed on the base portion 320.

At this time, the second cutter 314 may be movably disposed in a cross-sectional direction (X-axis direction) of the cut wire W with respect to the base portion 320, and the second cutter 314 may cross the first cutter 312.

That is, the wire cutting section 300 may further include a cutter driving section 360 that drives the second cutter 314 to move.

The cutter driving unit 360 is a moving structure for driving at least one of the pair of cutters 312 and 314, and may have various structures.

As an example, as shown in fig. 7, the cutter driving part 360 may include: a connecting portion 364 which penetrates the opening portion 322 formed vertically in the base portion 320, is rotatably hinged to the base portion 320 by a hinge pin 362 in the opening portion 322, and is coupled to the second cutter 314 at one end; the connection driving portion 366 is coupled to the other end of the connection portion 364 so that the connection portion 364 rotates about the hinge pin 362.

The connecting portion 364 is formed to penetrate the opening 322 formed in the base 320 in the vertical direction, is rotatably hinged to the base 320 by a hinge pin 362 in the opening 322, and transmits the driving direction of the connecting driving portion 366 to the second cutter 314 after switching the driving direction.

At this time, the rotation axis of the connection portion 364 can be formed in a direction (Y-axis direction) perpendicular to the movement plane of the second cutter 314 by the hinge pin 362 provided in the opening portion 322.

As for the connection portion 364, the connection portion 364 may be combined with the second cutter 314 in various ways as long as the second cutter 314 is movable while the direction of the driving force of the connection driving portion 366 is converted to reach the second cutter 314 so that the front and rear surfaces of the second cutter 314 intersect with the first cutter 312.

For example, the connection portion 364 may be coupled to a clipper guide 314a through a guide groove 312a formed in the first clipper 312 in the moving direction of the second clipper 314, and the clipper guide 314a is coupled to the second clipper 314.

The connection portion 364 is rotatably combined with the cutter guide block 314a and the connection driving portion 366, respectively.

The connection driving unit 366 is coupled to the other end of the connection unit 364 to rotate the connection unit 364 about the hinge pin 362, and may have various configurations.

As an example, as shown in fig. 7, the connection driving part 366 may be composed of an actuator rotatably coupled to the other end of the connection part 364.

With this configuration, when the connection driving portion 366 moves the other end of the connection portion 364 in the first direction (the X-axis direction with reference to fig. 7), the connection portion 364 rotates about the hinge pin 362, and thus the one end of the connection portion 364 moves in the second direction (the-X-axis direction with reference to fig. 7) opposite to the first direction, so that the second cutter 314 coupled to the one end of the connection portion 364 moves in the second direction to intersect the first cutter 312.

In order not to cross the first cutter 312 and the second cutter 314, the above-described process may of course be performed in the opposite direction to the above-described process.

The upper and lower guide portions 330 are coupled to the base portion 320 to guide the base portion 320 to move up and down, and may have various configurations.

As an example, the upper and lower guide parts 330 may include: a fixing plate 332 forming a guide passage 331; the moving plate 324 is coupled to the fixed plate 332 by a guide block 335 so as to move the fixed plate 332 up and down, and the fixed plate 335 is coupled to the base 320 so as to move along a guide path 331 formed in the fixed plate 332.

The up-down driving part (not shown) may have various structures as a driving source for driving the base part 320 itself to move the base part 320 up and down or driving the above-described moving plate 324 up and down.

When the moving plate 324 is coupled to the base 320, the up-and-down driving unit drives the moving plate 324 to move up and down, and further drives the base 320 to move up and down.

For example, the up-down driving part (not shown) may be an actuator of various types such as a hydraulic pressure, a pneumatic pressure, etc., but is not limited thereto.

On the other hand, in order to insert the winding portion 200-side end of the yarn W cut by the yarn cutting portion 300 into the hole 13 of the winding bobbin 10 for final fixation, the end portion of the yarn W needs to be bent by about 90 ° in the direction of the hole 13.

Accordingly, the present invention may additionally include a yarn winding part 400 in addition to the yarn supplying part 100, the winding part 20, and the yarn cutting part 300, the yarn winding part 400 bending the terminal end of the yarn W cut by the yarn cutting part 300.

Here, the end of the yarn W cut by the yarn cutting section 300 means the terminal end of the yarn W on the winding section 200 side of the cut yarn W, and the length of the terminal end can be determined based on the bending position of the bent yarn W.

The length of the terminal end of the wire W may of course vary depending on the device design and the specifications of the winding reel.

The yarn winding unit 400 is a structure for bending the end portion of the yarn W cut by the yarn cutting unit 300, and may have various structures.

The yarn winding unit 400 is a winding unit 200-side distal end portion that bends the yarn W cut by the yarn cutting unit 300, and is therefore preferably provided between the planar yarn cutting unit 300 and the winding unit 200 as shown in fig. 5a to 5 d.

As an example, the filament winding part 400 may include: a support block portion 410 provided corresponding to a bending position where the wire W is bent; the moving pressing unit 420 is provided to be movable on the opposite side of the supporting block 410 with respect to the yarn W, and presses the distal end portion of the yarn W so as to bend the distal end portion toward the supporting block 410.

The support block 410 is fixed to a point on the installation surface where the end of the wire W is bent to determine the bending position, and may have various structures.

For example, as shown in fig. 6, the supporting module 410 may be formed of a column member, and forms a point of the supporting wire W when pressurized by a moving pressurizing unit 420, which will be described later.

The moving pressing part 420 may be disposed on the opposite side of the supporting block part 410 with respect to the wire W such that the distal end portion of the wire W is positioned between the moving pressing part 420 and the supporting block part 410.

Specifically, the moving and pressing part 420 is movably provided on the opposite side of the supporting block 410 with respect to the wire W so that the distal end portion of the wire W is bent toward the supporting block 410.

Accordingly, when the pressing part 420 is moved to press the terminal end of the yarn W, the terminal end boundary of the yarn W is supported by the supporting block 410, and the terminal end can be bent toward the supporting block 410.

However, the thread winding part 400 bends the thread W entering between the supporting block part 410 and the moving pressing part 420, and thus it is necessary to prevent interference between the thread W and the thread bending part 300 during the winding process.

Accordingly, as shown in fig. 2a and 4, the yarn winding unit 400 of the present invention is provided so as to be movable up and down during the winding of the yarn W around the winding bobbin 10 so as not to interfere with the yarn W.

That is, the thread winding unit 400 moves downward in a standby state while the winding shaft 10 winds the thread W so as not to interfere with the thread W, and then, when the winding shaft 10 finishes winding the thread W and the thread W needs to be bent, the thread winding unit 400 moves the thread W, which is bendable between the support block unit 410 and the moving and pressing unit 420, upward.

As shown in fig. 2c, when the bending of the yarn W is completed, the yarn winding unit 400 moves downward again to wind the yarn W on the next winding shaft 10.

The up and down movement of the thread winding part 400 may be achieved in various manners and structures.

In one example, the thread winding portion 400 is provided in the base portion 320, and the base portion 320 is provided with the thread cutting portion 300, so that the thread winding portion 400 can be moved up and down while being compactly configured as a whole.

At this time, the wire winding part 400 may further include a block member 430, and the block member 430 is disposed at the base part 320 and has a guide groove 432 formed thereon to guide the movement of the moving pressing part 420.

The module member 430 is provided on the base 320 to move up and down together with the base 320, and has a guide groove 432 formed thereon to guide the movement of the moving pressing part 420.

The guide groove 432 may be formed in various planar shapes and depths as a groove for guiding the movement of the moving pressing part 420.

However, when the guide groove 432 is simply formed in a linear direction, even if the pressing portion 420 is moved along the guide groove 432 to bend the wire W, there is a problem that the wire cannot be bent at a desired angle.

Since the wound yarn W is itself provided with an elastic force to return to its original shape, it is necessary to move the moving pressing portion 420 to bend the yarn W at an angle larger than a desired bending angle.

Accordingly, in the present invention, the guide groove 432 may be formed with a curved groove portion 435 at the support module portion 410 side end, the curved groove portion 435 being flat in shape so as to be bent toward the support module portion 410.

Since the curved groove 435 is formed to be curved toward the support module 410, the distal end portion of the yarn W can be curved toward the support module 410 at a greater angle when the moving pressing part 420 moves along the curved groove 435. Accordingly, the final bent terminal portions of the wires W can be maintained in a state bent at a desired angle (e.g., between 85 ° and 95 °).

At this time, the moving pressurization part 420 may include: a pressing member 422 that comes into contact with the distal end portion of the wire W when the wire W is bent; a movable arm 426 coupled to the pressing member 422 and coupled to the block member 424 so as to be movable along the guide groove 432; the moving arm driving unit 428 drives the moving arm 426 to move.

As shown in fig. 10, the pressing member 422 may be formed of various materials such as metal and resin as a member that is bent at a position corresponding to the wire W and directly contacts the wire W, and the pressing member 422 may be formed in a cylindrical shape that minimizes friction with the wire W in consideration of movement of the moving pressing part 420.

In the case where the pressing member 422 has a roller shape, a groove 422a may be formed around the outer surface of the pressing member 422 along the contacting yarn W in order to stably press the yarn W.

The movable arm 426 is coupled to the pressing member 422, coupled to the block member 424, and movable along the guide groove 432, and may have various structures.

The movable arm 426 may be formed in various shapes according to design as a main body for providing the pressing member 422.

As an example, the moving arm 426 may include: a guide block 421 movably coupled to the guide groove 432; and an arm 424 coupled to the guide block 421 and the moving arm driving part 428.

The guide block 421 is a structure that moves along the guide grooves 432 and 435, and may be formed of various shapes and materials.

For example, as shown in fig. 10, the guide block 421 may be formed in a roller shape, inserted into the guide grooves 432, 435 and minimizing friction generated by movement, while being movable along the curved groove portion 435, but is not limited to the above-mentioned shape.

The arm 424 is a main body portion on which the guide block 421 is provided, and is coupled to the movable arm driving portion 428 so that the pressing member 422 is movable together with the guide block 421.

The arm 424 may be formed of various structures, shapes, and materials according to the design of the apparatus and the shape of the guide block 421 or the pressing member 422.

For example, as shown in fig. 10, the arm portion 424 may have an H-shaped cross section in the X-Z plane, a pressing member 422 may be inserted into the center of the distal end, and a bolt member and a guide block 421 for coupling the components may be provided on the upper and lower surfaces, respectively.

The movable arm driving unit 428 is a driving source that is coupled to the movable arm 426 to drive the movable arm 426 to move. There may be various ways; for example, the moving arm driving part 428 may be constituted by an actuator of air pressure, hydraulic pressure, or the like.

On the other hand, in the case where the curved groove 435 is formed at the distal end of the guide groove 432, in order to smoothly move the guide block 421 of the moving arm 426 along the curved groove 435, it is necessary to rotatably provide the moving arm 426, particularly the arm 424, to the moving arm driving part 428 with reference to the hinge axis (dotted line in fig. 10).

Accordingly, the moving arm driving part 428 may further include a connection part 425 rotatably coupled by the arm 424 and the hinge coupling part 427.

Accordingly, the arm 424 is rotatable by the connecting member 425 through the hinge coupling member 427, and thus the guide block 421 coupled to the arm 424 is movable along the curved groove portion 435 of the curved shape while the arm 424 is rotated.

Hereinafter, a process of winding the yarn W by bending the cut distal end portion of the yarn W after cutting the yarn W by the yarn processing device having the above-described structure will be described with reference to fig. 2a to 3.

As shown in fig. 2a, while the winding bobbin 10 is winding the yarn W, the yarn cutting section 300 and the yarn winding section 400 move downward to be in a standby state so as not to interfere with the wound yarn W, and then rise to the height of the yarn W when the winding of the yarn W is completed. At this time, the yarn cutting unit 300 and the yarn winding unit 400 are placed between the yarn fixing unit 350 and the yarn retreat blocking unit 900, and the yarn W is fixed to both sides.

When the fixing of the wire W is completed, the wire W is cut by the wire cutting section 300 as shown in fig. 2 b.

When the cutting of the yarn W is completed, the yarn winding portion 400 bends the winding portion 200-side distal end portion of the yarn W toward the fixing hole 13 of the winding bobbin 10 as shown in fig. 2 c.

The bent wire W is inserted into the hole 13 of the winding bobbin 10 through the wire fixing part 350, and finally, the winding of the wire W on the winding bobbin 10 is completed.

Finally, the winding bobbin 10, which has completed winding, may be discharged to the outside through the bobbin discharging part 700.

Accordingly, the yarn processing apparatus of the present invention has the following advantages: when the winding of the yarn on the winding bobbin 10 is completed, the yarn W is cut at a predetermined position, the yarn W is bent and fixed on the bobbin, and the winding of the winding bobbin 10 is completed, and thus, it is not necessary to input additional labor during the completion of the winding process, thereby automating the entire process from the loading of the empty winding bobbin 10 to the unloading of the winding bobbin 10, and finally automating the process of winding the yarn on the plurality of winding bobbins 10.

Accordingly, the present invention can minimize labor required for winding the yarn, and can rapidly wind the yarn around the plurality of winding bobbins 10, thereby having an advantage of greatly improving the overall productivity of the apparatus.

The above description is only a part of the preferred embodiments that can be realized by the present invention, and therefore it is well known that the scope of the present invention is not limited by the above-described embodiments, and the technical ideas of the present invention and the fundamental technical ideas thereof described above should be entirely included in the scope of the present invention.
