BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for automatically fastening the wound ends of a filament made of organic or inorganic material wound onto a reel.

0002

[Prior Art] Conventionally, as a method for processing the winding end of a filament that has been wound onto a reel, for example, the elastic force of an elastic member such as a leaf spring disposed on the reel is used. In addition, a worker forms a loop near the end of the filament, winds it around a reel, inserts the end of the filament into the loop, and tightens it in the opposite direction to the winding direction. There are methods to do this, but each method requires work by an operator and has the disadvantage that it is difficult to expect a reliable fastening process.

[0003] In order to solve these drawbacks, various methods have been proposed for automatically fastening the wound ends of the filament.
For example, JP-A-61-162,469 discloses that a filament body located between a reel that winds the filament body and a traverser that reciprocates in the axial direction of the reel to guide the filament body is used as an engaging member. The engagement member is rotated around the reel axis in a direction opposite to the winding direction to form a loop and wound around the reel, and the end of the filament is inserted into this loop and fastened. Disclose the method.

0004

However, according to this method, when the engaging member is rotated around the reel axis to form a loop, the filamentary body located between the traverser and the engaging member Because it is wound in the opposite direction to the winding direction, it comes into contact with the filament wound around the reel over substantially one round or more. That is, due to the rotation of the engaging member when creating a loop, the filament portion on the winding end side strongly rubs against the surface of the coil filament at a speed that is approximately twice the relative speed between the reel and the engaging member. In addition, it is difficult to ensure the characteristics of the striated body parts, and the smooth movement of the engaging member is impaired. , there was a problem in that so-called "unraveling" was likely to occur. The present invention has been made in view of these problems, and provides a method for winding a filament body that can automatically and reliably wrap the ends of the filament body around a reel when winding the filament body around a reel. Its purpose is to provide such equipment.

[0005]

[Means for Solving the Problems] In order to achieve this object, in the method of the present invention, when the wound end of the filament wound on a reel is fastened, the unwound filament is reeled. The unwound wire is rotated relative to the winding direction around the axis, engaged with a guide provided on the outside of the reel to form a loop, and then unwound by relative rotation of the unwound wire around the reel axis. The striatum portion is positioned in correspondence with the area defined by the loop, and while the spool line slit is held in that state, the striatum portion positioned within the loop area is cut, and the reel spool is cut. The cut end of the filament that is continuous with the wire is gripped and the loop is slipped under, and the cut end of the filament is relatively rotated in a direction opposite to the rotational direction to fasten the winding end.

[0006] Furthermore, in the device of the present invention for fastening the wound end of a wire wound on a reel, the unwound wire is separated from the wound wire in the radial direction of the reel. The guide part includes a guide part that guides the reel in the circumferential direction, a fastening part that is disposed opposite to the guide part and is movable in the reel axial direction, and a holding part that holds the winding wire body in the wound state. has a rotary plate that is rotatable around the reel axis, and a guide that is spaced apart from each other in the circumferential direction of the rotary plate and guides the unwound wire body in the circumferential direction of the reel; As the wound wire body rotates relative to the reel in the winding direction, it engages with the unwound wire body portion to form a loop,
a loop locking device capable of releasing the formed loop; and gripping a portion of the unrolled strand that is continuous with the coiled strand in accordance with the loop position by further relative rotation of the unwound strand; The cutting device has a cutting device capable of cutting the wire, and by moving the fastening portion in a direction away from the guide portion, the cut end of the cut filament is inserted into the released loop and fastened. Preferably, the guide section is provided with a holding device for holding the cut end of the unwound filament.

[0007]

[Operation] A loop can be formed at the winding end of the filament without contacting the filament already wound on the reel, so problems caused by contact with the coil filament will not occur. There is no. Moreover, when the end portion of the coiled wire body is inserted into a loop formed near the winding end of the coiled wire body, since the coiled wire body is held in the coiled state, there is no possibility that the wire body will come apart. The winding end can be securely fastened without any problems.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the drawings. FIG. 1 is a schematic diagram showing a winding end fastening device for a filamentous body according to the present invention, in which a guide portion 10 and a fastening portion facing the guide portion via a reel 14 on which a filament body 12 is wound are shown. 16. Note that reference numeral 18 is a traverser that reciprocates in the reel axis direction, and aligns the wound filament and guides it to the reel.

As shown in FIG. 2, the guide section 10 has a ring-shaped rotary plate 20 and a plurality of guides 22 arranged on one side thereof. These guides 22 are spaced apart from each other at predetermined intervals in the circumferential direction of the rotary plate 20 so as to be spaced apart from the reel 14 and, furthermore, from the filament wound thereon by a certain distance. Guide rollers 24 are disposed substantially parallel to the axis and spaced apart from each other, and are rotatably attached to the free ends of each of the guide rollers 24 for guiding the unwrapped wire strip 12 away from the reel and around the reel. Note that the reel 14 is connected to a shaft 26 of a rotational drive device (not shown) through a central opening 20a of a ring-shaped rotary plate 20, and is rotatable around its axis.

Preferably, the guide roller of one of the guides 22 is as shown in FIG. 2(b).
The guide includes a pair of guide rollers 24a that can be separated from each other in the axial direction of the guide, and a spring member 28 in which these rollers are disposed inside the guide body, and the pair of guide rollers are moved toward each other by the elastic force of the spring member 28. The configuration is configured to press the button so that the As a result, when the rod 30 connected to one roller is pressed in the direction shown by arrow A against the spring member 28, a gap larger than the outer diameter of the filament is formed between the pair of rollers. , a part of the unwrapped line strip guided along the guide roller falls into the gap. Then, when the pressed rod 30 is released, the pair of guide rollers are pressed by the elastic return of the spring member 28 and approach each other to sandwich the filament 12 and move the filament to the rotary plate 20. It can be held integrally against the

On the other hand, the guide portion 10 is connected via the shaft 26 and the reel 14 integrally connected thereto.
As shown in FIG. 3, the fastening portion 16 facing the cutting device 32 grips and cuts the filament 12 and engages with the filament 12 to form a loop at the winding end thereof. On the other hand, it is provided with a loop device 34 capable of releasing the formed loop.

The cutting device 32 has a support member 38 fixed at one end to a mounting plate 36, and a sleeve 40 is coaxially disposed within the support member 38 for axial movement. The support member 38 has a step portion 38a that protrudes radially inward and continues in the circumferential direction in the middle thereof, and the sleeve 40
has a stepped portion 40a that protrudes outward in the radial direction and continues in the circumferential direction on the outer peripheral portion of the free end side of the cylindrical body. Those steps 3
A compression spring 42 is disposed in the space defined by 8a and 40a, and is elastically deformed as the sleeve 40 and the support member 38 relatively approach. Further, the sleeve 40 has a shoulder portion 40b on the inner circumferential surface on the side away from the mounting plate 36, and the shoulder portion is formed as the output shaft 44a of the hydraulic cylinder 44 fixed to the mounting plate 36 retreats. Output shaft 44
engages a cutting member 46 disposed at the free end of a. Therefore, the compression spring 42 is elastically deformed due to the retraction of the sleeve 40 due to the engagement of the cutting member 46 with the shoulder of the sleeve 40, while the extension of the cylinder output shaft 44a in the direction of the guide means 10 Accordingly, the sleeve 40 is restored and expanded to press the sleeve 40 in the direction of the predetermined position.

Further, the supporting member 38 has a protruding portion that protrudes in the axial direction facing the guide means 10 formed on its end face, and the gripping jaws 50 are integrally fixed to the end face of the protruding portion. This gripping jaw 50 cooperates with the remaining end face portion of the support member 38 to form a gripping groove 48 . The groove width of the gripping groove 48 and the width of the recessed portion of the cutting member 46 are such that the width of the filament body located between the reel 14 and the guide roller 24 can be accommodated, that is, the width is at least larger than the outer diameter of the filament body 12. Any material having a large groove width may be used. Therefore, due to the relative movement between the cutting member recess and the gripping jaws as the hydraulic cylinder expands, the cutting member 46 is accommodated in the portion defined by the gripping groove and the recess of the cutting member 46 aligned as the hydraulic cylinder expands. It is possible to press the filament into the gripping jaws and grip it immovably, while further extension of the cylinder allows the filament to be cut. Note that the gripping jaw 50 has a through hole 50a extending in the direction of movement to allow movement of the cutting member 46 due to expansion and contraction of the hydraulic cylinder 44.

On the other hand, the loop device 34 has a locking member 52 that is offset radially outwardly from the gripping jaws 50 with respect to the axis of the output shaft of the hydraulic cylinder 44 constituting the cutting device. That is, in this embodiment, the locking member 52 is fixed to the outer surface of the support member 32 so as to face the gripping groove 48 . Furthermore, in order to facilitate the accommodation of the filamentary body 12 in the gripping groove 48, the mutually opposing portions of the gripping jaws 50 and the locking member 52 are chamfered.

The locking member 52 engages with the unwound filament to form a loop when the unwound filament rotates relative to the reel axis in the winding direction. As clearly shown in FIG. 3(b), the cross-sectional shape is arcuate. However, it goes without saying that it is not necessarily limited to this embodiment, and various shapes can be applied. Further, the locking member 52 has a groove 52a that substantially bisects its arcuate cross section and extends spaced apart substantially parallel to the axis of the hydraulic cylinder 44. A release member that pushes the filamentous part that forms a loop by being locked along the arcuate outer surface of the locking member in the direction of the opposing guide means to release the filamentous part in the groove 52a. 54 will be installed. Therefore, the release member 54 has a geometry such that at least a portion thereof protrudes from the surface of the locking member 52. Further, it is connected to an output shaft 56a of another hydraulic cylinder 56 via a connecting plate 54a, and the release member 54 is reciprocated in the direction of the guide means 10 along the groove 52a by expansion and contraction of the cylinder output shaft 56a. Then, the mounting plate 36 to which the cutting device 32 and the loop device 34 are attached is attached to the arm 58.
Attach to. This arm 58 is driven by a drive device 60 in a direction towards or away from the guide means 10.

Furthermore, the device of the present invention includes a holding portion 64 that holds the filament wound on the reel 14 from the outside. This holding part 64 includes a pair of pressers 66 diametrically opposed to the filament wound on the reel 14, a pair of rods 68 that respectively support the pressers, and a guide means 10 that opposes the rods. It has a drive device 70 that can reciprocate toward the target and move them closer to each other. Then, based on the operation of the drive device, the wire approaches the reel 14 on which the wire is wound, and the pair of pressers 66 presses the wire from the outside to "unravel" the wire. and maintains the striatum in its coiled state.

Next, a description will be given of how the winding ends of the filament wound around the reel are fastened according to the present invention. As schematically shown in FIG. 1 or 4, a ring-shaped rotating plate 20
The traverser 18 reciprocates in the reel axis direction in cooperation with the rotation of the reel 14 connected to the shaft 26 of a rotary drive device (not shown) in the direction shown by arrow B through the central opening 20a of the reel 14 and the rotational movement of the reel 14. Exercise causes the striatum 12
are lined up on the reel 14 and wound by a predetermined amount. In this case, since the rotary plate 20 does not rotate, the filamentary body 12 passes between adjacent guides 22 provided therein and is wound around the reel, thereby hindering the winding operation of the filamentous body. It never happens.

Next, as shown in FIG. 5, the guide roller 24a and the traverser 1 form a pair that can be separated in the axial direction.
8 to the unwound filament 12 between the traverser and the reel 14, while the fastening means is moved to a position where the locking member 52 of the fastening means 16 intersects the unwound filament 12. The guide means 10 is approached. However, since the rotating plate 20 is not moving in this state, the unwound wire body 12
does not engage with the locking member 52 and the pair of guide rollers 24a.

Therefore, when the rotation of the reel 14 is stopped and the rotating plate 20 is rotated in the direction shown by arrow C in FIG. The unwound filament that is continuous with the filament that has been
As the fastening means 16 rotates, the fastening means 16, specifically its locking member, engages with the pair of guide rollers 24a and moves in the circumferential direction of the reel, and is placed in an immovable state with respect to the rotary plate 20. 52. Then, by further rotating the rotating plate 20, a loop 70 is formed between the fastening means 16 and the reel 14, as shown in FIG. 6(b). Note that the unwound filament is smoothly unwound in accordance with the rotation of the rotary plate 20 because each guide roller 24 engaged with the guide 22 can rotate around its respective axis.

By further rotating the guide roller 24a with which the linear body forming the loop 70 engages, as well as the rotary plate 20 to which it is attached, the plurality of guides 22 provided thereon are rotated.
The unwound filament is sequentially engaged and wound into a spinning wheel shape, and the rotation is stopped before the pair of guide rollers 24a rotate approximately once. This situation is shown in FIG. 7(a). Then, as shown in FIG. 7(b), the unwound filament gradually supplied via the traverser 18
6 is separated from the rotary plate 20 along the reel axis direction to a position where it does not engage with the locking member 52 of the fastening means again. At this time, the filament that engages with the locking member 52 to form a loop is maintained in the locked state by the frictional force generated between it and the locking member, and therefore falls off from the locking member. Never.

While maintaining the fastening means 16 in its retracted position, the rotary plate 20 is again rotated in the reel winding direction as shown in FIG. The filament body located between the fastening means 1
6 to a position corresponding to the gap formed between the chamfered portions of the gripping jaws 50 and the locking member 52. At this time,
As shown in FIG. 8(b), the traverser 18 is moved in parallel to the direction of the rotary plate 20, and the filamentous body gradually supplied via the traverser overlaps the filamentous body already engaged with the guide 22. I'll make sure this doesn't happen. This can reliably prevent the unwound filament from overlapping the filament already guided by the guide roller 24a.

As is clear from FIG. 8(c), the fastening means 16, which was in the retracted position, is moved forward toward the rotary plate 20, while the rotary plate 20 is rotated in the direction of winding the filament, and the reel is rotated. The gripping jaws 50 provided on the support member 38 and its protruding portion include a linear body located between the support member 38 and the guide roller 24a.
into the gripping groove 48 formed between the two. On this occasion,
Since the mutually opposing end surfaces of the gripping jaws 50 and the locking member 52 are chamfered, the filament can easily fit into the gripping groove along these surfaces.

Therefore, the rod 30 associated with the guide roller 24a is pressed against the spring member 28, and the paired rollers are separated from each other to form a gap.
The filament body guided by a is placed in the gap and the rod 30 is released. As a result, only the filament bodies already guided by the guide rollers 24a can be gripped by the pair of guide rollers 24a. Here, gripping the filament body 12 by the guide roller 24a spaced apart from the reel 14 is as follows.
This is useful in improving work efficiency since the filament will not become tangled during the subsequent winding and tightening work. Then, the holding part 64 disposed on the outer periphery of the reel 14 on which the filamentous body 12 is wound is operated, and the opposing pressers 66 are brought close to each other via the reel 14.
The coiled circuit strip is held by pressing it from its outer periphery. This situation is shown in FIG. 9(c).

Next, as shown in FIG. 10, the fluid pressure cylinder 44 of the fastening means 16 is operated to connect the output shaft 44a.
When extended, the cutting member 46 shown in FIG. 3(a) moves in the direction of the gripping jaws 50, gripping and cutting the filament portion accommodated in the gripping groove 48 and the recess of the cutting member. Therefore, when the loop device 34 is activated and the release member 54 is pressed in the direction of the rotary plate 20, the forward movement of the release member 54 also pushes the loop engaged with the locking member 52 in the direction of the rotary plate, causing the loop to engage with the locking member 52. can be solved. At this time, the cut portion of the filament located on the reel side is pressed and held between the cutting member 46 and the gripping jaws 50, and the other cut portion is held between the pair of guide rollers 24a. It is in.

Then, by moving the fastening means 16 back again in the direction away from the rotating plate 20, the reel-side linear body whose end portion is gripped by the cutting device 32 is disengaged from the locking member 52. It can be hidden inside the loop. However, in this state, the cut portion of the reel-side filament simply passes through the loop, and the loop is not substantially tightened. Therefore, the fastening device 16 is
), by rotating the filament around the axis of the reel 14 in a direction opposite to the winding direction of the filament, the filament can be tightened and its ends can be fastened.

[0026]

[Effects of the Invention] Thus, according to the present invention, a loop is formed at the end of the filament body which is wound in alignment with the reel by rotating the filament body around the reel in the same direction as the winding direction of the filament body. The end of the wire is inserted into the loop and automatically tightened, so that the reel wire and the unrolled wire do not rub against each other when creating the loop.
It does not damage the striatum. Moreover, since the striated body can be automatically fastened, it is possible to perform the fastening work more reliably than the conventional fastening work by a worker, and it also reduces the burden on the worker and the number of work steps. In addition, it can greatly contribute to the development of industry by improving work efficiency.
