Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an aligned winding method for a filament such as an optical fiber cable or an electric cable, and particularly to an automated aligned winding method for a filament.

``Prior Art'' Conventionally, when winding a filament such as an optical fiber cable or an electric cable around a drum, in order to prevent winding irregularities, the devices shown in FIGS. 6 to 8 are used to wind the wire in an aligned manner. was there.

That is, as shown in FIG. A traverser 5 that can adjust the angle θ) is installed in the vicinity of the drum 3 so as to be freely movable in parallel, and while adjusting the angle and position of the traverser 5, the filament 4 is wound in alignment around the winding drum l.

In this case, each time the drum 3 rotates once, that is, each time the filament 4 is wound around the winding drum l, the traverser 5 tilts from a direction perpendicular to the central axis of the winding drum l, and angle (e.g. 2°).

When the angle of the traverser 5 reaches a specific angle, it is translated in parallel by a predetermined distance in the direction of arrow a in FIG. 6 to return its inclination angle to 0°. In this way, by sequentially repeating the operation of moving the traverser 5 in parallel again when the angle of the traverser 5 reaches the above-mentioned angle, □, the striatum 4 of the next revolution is sequentially moved to the striatum 4 of the previous revolution. The layers are aligned and wound while being aligned.

At the end of the winding drum l near the flange plate 2, a vertical roller is installed as shown in FIGS. 6.6, and when the filament 4 is wound once around these vertical rollers 6, the traverser 5
The filament 4 is folded back by reversing the layers, and the layer is wound in the same manner as above in the opposite direction to the number of layers.

In this way, the filament 4 is wound around the drum 3 in multiple layers.

"Problems to be Solved by the Invention" By the way, when winding the filament 4 around the winding drum 1, if the winding is disordered or there are overlapping parts, it may be difficult to pull out the filament 4 from the winding drum 1. The portion to be removed may be pressed down by the overlapping filament 4, and in such a case, attempting to forcefully pull out the filament 4 may result in damage to the filament 4.

In the conventional method, when winding the filamentous body 4, there is a problem in that the portion of the winding drum l near the collar plate 2 tends to have irregular winding as described below, which is not preferable as described above.

That is, as shown in FIG. 9, the filament 4 that has been sequentially wound toward the flange plate 2 is wound, for example, to the inner surface of the flange plate 2 as shown in FIG. When wrapping the second layer of striae 4,
First, as shown in FIG. Because the traverser 5 moves after being wound around the winding drum 1 and the traverser 5 is tilted at a specific angle, the top of the second layer 4 As shown by the dotted line in Figure 11, the striatum 4
Sometimes it got wrapped up.

In this way, when the next filament body 4 to be wound next to the second layer filament body 4 at the end of the winding drum 1 is overlaid on top of the filament body 4, this filament body 4 is wound as described above. This was a cause of disorder and empty rolls.

In addition, in the case where the optical fiber cable or electric cable that is the filament body 4 has a multi-M structure or a twisted structure,
Since each layer is made of a member having a different elastic force, when the filament 4 is wound around the drum 3, the filament 4 causes undulations on the drum 3, causing irregular winding.

Therefore, it was necessary to correct the undulations each time it was wound around the drum 3. In particular, if undulations occur at the beginning of winding or at the folded end, gaps or overlaps are likely to occur when pattern winding is performed at the middle part.

However, in the conventional method described above, since the winding points of the traverser 5 and the drum 3 are far apart, it is not possible to eliminate the waviness even if the inclination or position of the traverser 5 is forcibly corrected. In addition, there is no means to detect waviness or disordered winding of the filament body 4, and workers must constantly monitor the winding condition near the drum, and if waviness or the like occurs, the device must be stopped. There was a problem in that it had to be rolled up and then re-wound.

The present invention has been made in view of the above circumstances, and its purpose is to enable the winding of the striatum to be carried out without the need for workers to monitor the condition.
To provide an aligned winding method for a filament body, which can automatically eliminate waviness on the drum and wind the filament body around the drum in an aligned state without causing winding gaps or disordered windings.

``Means for Solving the Problems'' The present invention provides a drum consisting of a winding drum and a collar plate integrated at both ends of the winding drum, in which filamentary bodies such as cables are arranged in multiple layers and arranged in each layer. In the aligned winding method of the filament bodies, when the next round of the filament bodies is wound along the filament bodies wound in the previous round in each layer, parallel light is projected onto them and the reflected light is is detected, and the mutual positional relationship between the axial center position of the striatum in the previous round and the axial center position of the striatum in the next round wound next to it is determined from the density information of the detected reflected light, and the detection result is calculated. If the drum is not aligned with the linear body of the next revolution or the linear body of the previous revolution, the drum is detected along at least one of a plane parallel to the central axis of the winding drum or a plane including the central axis of the winding drum. Based on the result, the next round's striatum is aligned along the previous round's striatum I while rotating at a predetermined angle.

Then, when the filament body that has been wound up to the vicinity of the flange plate is further wound in the direction of the flange plate and the filament body follows the flange plate, overlapping of the filament body is detected based on the density information of the reflected light, The drum is rotated at a predetermined angle along at least one of a plane parallel to the central axis of the winding drum or a plane including the central axis of the winding drum in a direction in which the filamentary body follows the collar. When the drum is rotated once after detecting the shape, the drum is wound on at least one surface parallel to the central axis of the winding drum or a surface that includes the central axis of the winding drum. Aligning the filament bodies of the next round along the filament bodies of the previous lap at the overlapping ends along the collar plate by rotating at a predetermined angle in a direction opposite to the rotation direction along one side. It is characterized by

"Function" According to the method for aligning and winding a filament according to the present invention, even if the filament wound around the winding drum of a drum is misaligned or undulated due to empty winding or pile-up, the rotation of the filament can be continued. Since the mutual positional relationship between the striatum and the striatum of the previous rotation is optically detected, by rotating the drum based on the detection result, in other words, the position of the entrainment point of the striatum can be adjusted. By forcibly shifting along the direction or the direction of waviness, it is possible to automatically correct the misalignment or waviness of the filament.

In addition, when the filament reaches the vicinity of the collar plate and is folded back, the overlapping of the filament at the folded end is optically detected and the drum is rotated slightly in the direction in which the filament is along the collar plate. By moving the drum, the filament can be wound along the collar, and when the filament has been overlapped once, the drum is rotated in the opposite direction to the rotating direction, that is, in the same manner as above. By slightly shifting the winding point of the filament, the next rotation of the filament can be automatically made to follow the filament that runs along the collar without overlapping the filament.

“Example” An example of the method for aligning and winding a filament according to the present invention will be described with reference to the drawings.

The apparatus used in this first embodiment will be explained with reference to FIGS. 1 and 2. The drum 10 has a winding drum 1.
The rotating shaft of the drum 10 is supported by a frame-shaped support member 13.

The bottom center of the support member 13 is supported by the center of the turntable 15 via a hinge member 14, and a cylinder device is provided between both ends of the support member I3 and the outer circumference of the turntable 5. 16°16 is provided.

The turntable 15 is horizontally rotatable, and rotates the drum 10 in a plane parallel to its central axis (in this example,
to be able to rotate at the required angle along the horizontal plane), and
The drum lO is supported by a cylinder device 16, 16 so as to be rotatable at a required angle along a plane (vertical plane in this example) including its central axis.

Also, similar to the conventional example shown in FIG. 6, near the drum lO,
A traverser 17 is provided so as to be able to move in parallel and adjust its angle, and a first optical sensor is provided above or below the traverser 17 to detect the position and angle of the traverser 17 using images.

Furthermore, as shown in FIG. 2, a second optical sensor 18 for monitoring the winding point of the drum IO is provided at a position diagonally above and outside the winding point of the drum IO.

This second optical sensor 18 is connected to Ll provided on the other side.
Parallel light projected from a light source 19 such as an e-Ne (helium-neon) laser is reflected on the striatum S, and the reflected light is received. In this case, the dark part of the reflected light is the striatum. It is the axis of S.

This second optical sensor 18 is connected to an image processing system that analyzes the density information of the detection light received by the optical sensor 18 and detects the axis position of the striatal body S.

As shown in FIG. 2, this image processing system includes, for example, an image processing unit 20 that converts analog image data detected by the optical sensor 18 into digital data to detect grayscale information; a storage unit 21 that temporarily stores the image data digitized in step 20, and a comparison unit 22 that compares the axis position of the striatum S from the image data of the curve stored in the storage unit 21 and the current image data. and a control section 23 that controls the drive of the cylinder 16 or the rotation angle of the turntable 15 based on the comparison result of the comparison section 22.

When winding the first layer using the device configured in this way, each time the drum 10 rotates once, that is,
Each time the filament S is wound around the winding drum 11, if the traverser 17 is tilted by a specific angle (for example, 2 degrees) from the direction perpendicular to the central axis of the winding drum 11, the position and angle are changed. 1 optical sensor, and drives the traverser drive motor to move the traverser 17 in parallel by a predetermined distance to return the inclination angle to 0°. Repeat this action,
Wrap the first layer.

During these operations, the striatum S has a winding trunk l! A parallel light (laser light) is projected from a light source 19 at a point where the winding is performed. This parallel light wraps around the striatum S
It is reflected by the second optical sensor 18 and detected as shown in FIG. 3(A). The detection signal of the reflected light detected by the second optical sensor 18 is determined in the image processing system by the distance between the axial position of the wrapping point of the striatum S in the previous round and the axial position of the striatum S in the current round. X is detected.

At this time, the axis of the striatum S in the current round is the same as the striatum S in the previous round.
If waviness or positional deviation occurs not along the axis of the wire, for example, if the interval In other words, when the turntable 15 is rotated in the direction in which the striatum S is shifted, the drum 10 is rotated, and the winding point is shifted, and the winding is continued, the striatum S of the current rotation is aligned with that of the adjacent previous rotation. It moves closer to the striatum. In addition, if the interval When the turntable 15 is rotated in the opposite direction and winding is continued, the wrapping point is slightly shifted in the wrapping direction, and the striatum S of the current round slides off from the striatum S of the previous round. In this way, the overlap is resolved, and the striatum S of the current round is aligned with the striatum S of the previous round. When winding the same layers like this,
The second optical sensor 19 monitors the rolling state of the filament S, and when a positional shift or waviness occurs, the turntable 15 is rotated by a predetermined angle in the direction of the displacement of the filament S, and the drum IO is The wrapping is corrected by forcibly shifting the point.

Next, when the striatum S wraps around the next layer,
That is, the end of the winding drum 11 near the collar plate 12 (
In Fig. 4 (a) state), the winding drum! 1 and the winding speed of the filament S is reduced. Then, after the final striatum S of the first layer is wound along the collar plate 12, the fourth striatum S is wound.
When the second layer overlaps the end of the first layer as shown in FIG. 3(b), and the second optical sensor 18 detects this overlap, that is, the step Y as shown in FIG. 3(b), 1st
Drum lO by driving the cylinder I4 on the end side of the layer upward.
(see Figure 4 (c)). Then, when the winding is continued, the filament S is wound along the collar plate 2 side. Furthermore, when the second optical sensor 18 detects the shape and the drum 10 rotates once, that is, when the filament S in the first rotation of the second layer starts the second rotation, the cylinder 14 is moved from the horizontal state. Further lower the drum IO and tilt it in the opposite direction (approximately 30 degrees).
The striatum S in the second round of the second layer is the striatum S in the first layer of the second layer.
10 so that it does not overlap. That is, in this case, the drum IO is tilted as shown in FIG. 4 (d),
As shown in FIG. 4(e), the second round of the filament S of the second layer is slid down from above the filament S of the first layer of the second layer and placed next to it. When the vicinity of the starting end of the filament S in the second round is located next to the filament S in the first layer, the cylinder 14 is raised again and the flange plate 12 is injected with one layer, as shown in FIG. In the same way as the striated bodies S of the second layer are laid along the striated bodies S of the first layer. And the drum lO is 1
After rotating by 80 degrees, the winding drum 1 is returned to its original horizontal position (see Figure 4 (G)) and winding is continued, and the second layer of the filament S is
While moving the trapazer 17 in the same manner as described above, positional deviation is detected and the second layer is wound in alignment.

When the winding of the second layer reaches the opposite end of the winding drum 11, perform the same operation as described in i above to eliminate irregular winding and empty winding, and then repeat the above operation. By repeating this process, it is possible to perform aligned winding for the third layer, fourth layer, and so on up to the required layers.

Note that, depending on the diameter d of the filament S and the length of the winding drum, various states of lamination at the edge of the collar plate 12 appear as shown in FIG. When S was folded back along the collar plate [2], it was possible to wind the filament S in an aligned manner without any winding disorder.

Therefore, if the filament S is wound around the winding drum II using the method described above, even if misalignment such as waviness, winding gaps, or overlapping occurs, aligned winding without winding disorder or winding gaps can be achieved. Furthermore, the folding end portion can also be folded back automatically. Therefore, the winding drum 11
Even when wrapping a filament that requires care in handling, such as an optical fiber cable, the fiber optic cable can be wrapped and pulled out without damaging the cable.

In the above embodiment, the turntable 15 is rotated to correct the misalignment of the filament S in each layer, but the cylinder 16 is moved up and down. The drum 10 may be tilted to correct the positional shift of the linear body S.

Similarly, at the folded end, in the above embodiment, the cylinder I6 was driven to give the drum 10 an inclination, but the same effect can be obtained by rotating the turntable 15. Therefore, the present invention can be implemented even if the device is one that only horizontally rotates or one that only tilts.

"Effects of the Invention" As explained above, according to the method for aligning and winding filaments according to the present invention, when the filaments are wound on the drum, the filaments are sometimes misaligned such as winding gaps or overlapping. Even in the event of waviness, the mutual positional relationship between the filament in that rotation and the filament in the 671st rotation is optically detected, so the winding drum can be adjusted based on the detection results without the need for workers. Because it is rotated, in other words, the winding point of the filament is forcibly shifted in the direction where the positional deviation occurs, so that the winding is performed.
Misalignment of the striatum can be automatically corrected.

In addition, even when the filament reaches the vicinity of the collar plate and is folded back, the overlapping of the filament that has reached the folded end is optically detected, and the winding drum is slightly moved in the direction in which the filament follows the collar plate. By rotating the filament body, the filament body is wound along the collar, and when the filament body has been overlapped once, the winding drum is rotated in the opposite direction, that is, the filament body is wrapped in the same manner as above. Since the winding point is slightly shifted, the next round's filament can be automatically made to follow the filament along the collar without overlapping it.

Therefore, the filament can be wound accurately and continuously in a short period of time without requiring any manpower, and there is no trouble when starting the bow.
