Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a device for winding wire bodies such as electric wire cables onto a winding drum in an aligned manner.

[Prior art]

When winding the filament bodies onto a winding drum in an aligned manner, it is necessary to sequentially move the supply position of the filament bodies relative to the drum as the filament bodies are wound. When moving, the feeding position of the filament is delayed and moved so that the feeding angle of the filament to the drum is a certain negative angle with respect to the direction in which the filament is wound; A method is known in which wires are wound in an aligned manner.

Conventionally, as a device for performing such winding work, a main motor rotates the winding drum, and a continuously variable transmission, for example, changes the rotation speed of the main motor to a predetermined rotation speed, and also changes the rotation speed between the reference speed and high speed. The rotation of the transmission is further transmitted to a screw shaft disposed parallel to the rotational axis of the drum through a forward/reverse clutch mechanism, and normally the speed change By setting the machine to the standard speed and rotating the screw shaft at the standard rotation speed, the traverser attached to the screw shaft is moved, and if the feeding angle of the filament to the drum changes due to some external factor,
In other words, when the movement of the traverser becomes delayed or becomes faster, the angle detector installed in the traverser detects the variation in the supply angle, and the transmission is switched to the high-speed side or stopped, and the rotation of the screw shaft, that is, the rotation of the traverser is changed. Devices configured to speed up or temporarily stop movement are known.

However, in the winding device configured in this manner, since the transmission is of a stepped speed change type, the traverser that defines the feeding position of the filament is set at a predetermined reference speed or faster than that. The operation can only be performed by changing the rotational speed of the screw shaft, that is, the moving speed of the traverser, in a stepwise manner in three modes: fast speed and stop. It was not possible to make fine adjustments.

In addition, when the filament winds up and reaches a point along the flange plate of the drum, one turn of the filament at the beginning of the next layer is placed on top of the one turn of the filament along the flange plate. However, if the position where the filament is placed on the drum is the same in each winding layer, the filament wound around the drum may bulge at the position where the filament is placed on the drum.

In order to avoid such a situation, the rotation of the drum may be temporarily changed to change the point at which the filament rides on each wound layer, but in the case of the conventional winding device described above, the transmission is Since the rotation ratio is changed stepwise, it is not possible to finely adjust the moving speed of the traverser in response to the temporary rotational speed of the drum as described above.

On the other hand, as a winding device that can eliminate the above-mentioned disadvantages, a motor with a small rotor moment of inertia (GD ² ), that is, a variable speed motor with good response characteristics (called a minor shear motor), is used to drive the screw shaft. The rotational speed of the traverser is controlled by the output signal from the angle detector, and the moving speed of the traverser can be adjusted quickly and delicately in response to fluctuations in the feeding angle of the filament to the drum. A winding device is known that changes the winding speed to .

[Problem that the invention attempts to solve]

In such a winding device, the rotation speed of the screw shaft, that is, the moving speed of the traverser can be finely adjusted, so the feeding position of the filament can always be set at an appropriate position. Since the minersha motor used in this method is of special specifications and is expensive, there is a drawback that it imposes a heavy economic burden.

[Purpose of the invention, structure]

This idea was made in view of the above circumstances, and it is possible to finely adjust the moving speed of the traverser that defines the feeding position of the filament, and it is also possible to align and wind the filament, which can be manufactured at low cost. The purpose of this invention is to provide an angle detector 26 for detecting the feeding angle of the filament 24 with respect to the winding drum 1.
A traverser 22 having a guide member 25 that defines the feeding position of the filament body 24 is screwed onto a screw shaft 21 arranged parallel to the rotation axis of the winding drum 1, and the screw shaft 21 is rotated. In the alignment winding device, which is configured to move the traverser 22 in a direction parallel to the rotation axis of the winding drum 1 by driving, the screw shaft 21 is connected to a differential gear mechanism 17, and the screw shaft 21 is connected to a differential gear mechanism 17. The gear mechanism 17 is connected to a drive unit mainly composed of a variable speed motor controlled by the output signal of the angle detector 26, and the differential gear mechanism 17 is configured such that the output rotation speed of the traverser 22 is set to a predetermined standard. The output rotation speed of the differential gear mechanism 17 is changed by driving the screw shaft 21 at a rotation speed at which the screw shaft 21 is moved at the same speed, and by changing the rotation speed of the drive section according to the output signal of the angle detector 26. The device is characterized in that it is configured to increase or decrease the number of rotations of the filament body.

〔Example〕

Examples of this invention will be described below with reference to the drawings.

FIG. 1 is a plan view schematically showing an embodiment of this invention, in which a winding drum 1 is attached to a rotating support shaft 2 and is configured to rotate together with the rotating support shaft 2. There is. That is, the rotating support shaft 2 is connected to a relay shaft 6 via sprockets 3, 4 and a chain 5, and this relay shaft 6 is connected to a main motor 10 via other sprockets 7, 8 and a chain 9. Therefore, the drum 1 is configured to rotate together with the rotation support shaft 2 by driving the main motor 10. Further, the relay shaft 6 is further provided with a third sprocket 11.
The sprocket 11 is connected to the input shaft 14a of the continuously variable transmission 14 through the chain 12 and the sprocket 13, and the output shaft 14b of the continuously variable transmission 14 is connected to the input shaft 14a through the sprocket 15 and the chain 16. The input sprocket 17a is connected to an input sprocket 17a constituting a differential gear mechanism 17.

This differential gear mechanism 17 has an input sprocket 17.
a pair of rotatably supported intermediate gears 17b;
and an input gear 17c that meshes with each intermediate gear 17b.
The input gear 17c is connected to a variable speed motor 19 such as a DC motor via a worm reducer 18, and the output gear 17d is connected to a forward/reverse clutch mechanism 20. ing.

Further, a screw shaft 21 arranged parallel to the rotation axis of the drum 1 is connected to the forward/reverse clutch mechanism 20, and a traverser 22 is attached to the screw shaft 21. That is, the traverser 22 is screwed onto the screw shaft 21 and engaged with a guide shaft 23 disposed parallel to the screw shaft 21, so that the screw shaft 21 rotates forward and backward, thereby rotating the rotation axis of the drum 1, that is, the winding drum 1a.
The traverser 22 includes a guide member 25 including a guide roller for defining the supply position of the filament 24 to be wound around the drum 1, and body 2
4 to the winding drum 1a, that is, the winding drum 1
An angle detector 26 is attached to detect the angle θ formed between the surface along the radial direction of a and the supplied filament 24.

This angle detector 26 has a rod 26 that is rotatably attached to the end of the traverser 22 on the drum 1 side, and has a guide roller 26a that lightly holds the filament 24.
b, and a pair of detection switches 26c disposed on both sides of the rod 26b so as to be operated by the rod 26b, and when the rod 26b rotates together with the filament 24, one of the detection switches 26c is activated. Accordingly, the angle of the rod body 26b, that is, the supply angle θ of the filament body 24 with respect to the drum 1 is detected.

The detection switch 26c is the control device 28.
When it is detected that the feeding angle θ of the filament body 24 has become larger than the desired angle, the variable speed motor 19
(positive) direction or vice versa, if it is detected that the angle has become smaller than the expected angle, the variable speed motor 1
9 in the - (minus) direction.

In addition, 29a and 29b in FIG. 1 are the traverser 2.
Reference numeral 2 designates a position detection switch for detecting the limit position at which reverse movement should start and operating the forward/reverse clutch mechanism 20 to reversely rotate the screw shaft 21.

Next, the operation of the winding device configured as described above will be explained.

The normal moving feed amount (reference speed) for moving the traverser 22 is predetermined by the diameter of the filament 24, and therefore the reference rotation speed of the screw shaft 21 is also predetermined.

Therefore, first, the output rotation speed of the continuously variable transmission 14 is set so that the rotation speed of the input sprocket 17a of the differential gear mechanism 17 is 1/ of the reference rotation speed of the screw shaft 21.
2 in advance. Then, the guide member 25 that defines the starting position of the traverser 22, that is, the feeding position of the filamentary body 24, is moved slightly backward in the winding direction from the position corresponding to the first winding, so that the filamentous body 24 is If the main motor 10 is started at a position where the supply angle θ is a certain negative angle with respect to the winding direction, the drum 1
rotates and starts winding up the filament 24, and at the same time the traverser 22 begins to move.

In this case, the input sprocket 17a rotates at half the rotation speed of the predetermined reference rotation speed as described above, and the variable speed motor 19, that is, the input gear 17c is stopped, so that the screw shaft 21 is rotated at the reference rotation speed. The traverser 22 rotates at a rotational speed, and the traverser 22 moves at a reference speed, and as a result, the filament 24 is wound onto the winding drum 1a in an aligned manner.

While winding the filament 24 as described above, for example, if the rotation ratio preset to the continuously variable transmission 14 is slightly deviated from the expected rotation ratio, etc. If the traverser 22 deviates from the intended position due to some factor, and as a result, the feeding angle θ of the filament body 24 with respect to the drum 1 changes,
The rod 26b constituting the angle detector 26 is the striatum 2.
4, one of the detection switches 26c is operated, and as a result, the variable speed motor 19 is rotated forward or backward based on the output signal issued from the detection switch 26c.

In this case, the differential gear mechanism 17 is connected to the variable speed motor 1
9 is stopped, that is, the input gear 17c
Since the traverser feed rate is the normal amount when the traverser is stopped, when the feeding angle θ of the filament body 24 becomes large, that is, when the movement of the traverser 22 is delayed, the variable speed motor 19 moves the detection switch 2
The input gear 17c is rotated in the addition direction by the output signal of the output gear 6c, and as a result, the input gear 17c is rotated in the positive direction, thereby increasing the rotational speed of the output gear 17d, that is, the screw shaft 21, and the traverser 22 is acceleratedly moved.

Conversely, when the traverser 22 advances too far and the supply angle θ of the filament 24 becomes small, the variable speed motor 19 rotates in the deceleration direction by the output signal of the detection switch 26c, and the traverser 22 decelerates accordingly. will be moved.

Note that the detection switch 26c is operated by a change in resistance value or capacitance, and outputs a signal corresponding to the amount of change in the supply angle θ of the filamentary body 24. If the variable speed motor 19 is made to rotate in forward and reverse directions, the rotation speed of the variable speed motor 19 will change steplessly and subtly, causing the rotation speed of the screw shaft 21 to change subtly, and as a result, the traverser 22 will rotate. Movement speed can be fine-tuned.

As described above, when the traverser 22 is set to the desired position, the supply angle θ of the filament 24 becomes the desired angle, and as a result, none of the detection switches 26c is operated, so that it is possible to The variable speed motor 19 stops, and the traverser 2
2 moves at the standard speed and the feeding angle θ of the filament body 24 is
is maintained at the desired angle.

Then, when the filament 24 is wound and reaches a position along the flange plate 1b of the drum 1, and the traverser 22 reaches one of the limit positions, the traverser 22 operates one of the position detection switches 29a to The reverse clutch mechanism 20 is switched, and as a result, the screw shaft 21 is reversely rotated, the traverser 22 is reversely moved at the reference speed, and the second layer is wound.

Even if a situation occurs in which the traverser 22 is deviated from the intended position during the winding operation for the second and subsequent layers, the angle detector 26 and the variable speed motor 19 perform the operations described above. The traverser 22 is set to the desired position.

In the above embodiment, the input sprocket 17 to which the intermediate gear 17b of the differential gear mechanism 17 is attached
The rotation speed of the screw shaft 21 can be finely adjusted by rotating the input gear 17c at a predetermined rotation speed and changing the rotation speed of the input gear 17c meshing with the intermediate gear 17b using the variable speed motor 19. However, this invention is not limited to the above-mentioned embodiment. For example, the input gear 17c is rotated at a predetermined rotation speed by a predetermined drive source, and the rotation speed of the input sprocket 17a, that is, a pair of rotation speeds is changed. The rotation speed of the screw shaft 21 is finely adjusted by changing the revolution speed of the intermediate gear 17b with the variable speed motor 19, and the traverser 22
It may be configured to finely adjust the moving speed of.

Further, in the above embodiment, the input sprocket 17a of the differential gear mechanism 17 is configured to be rotated by the main motor 10, but the means for rotating the input sprocket 17a is arbitrary and is not limited to the main motor 10. .

Furthermore, the variable speed motor 19 is always rotated normally at a certain standard speed corresponding to the rotation speed of the drum 1,
The moving speed (or pitch) of the traverser 22 may be changed by accelerating or decelerating this rotational speed using the detection switch 26c.

Further, in the winding device of this invention, a forward/reverse clutch mechanism is not particularly necessary, and the traverser 22 is moved in the reverse direction by changing the rotation direction of the variable speed motor 19 and changing the rotation direction of the screw shaft 21. Good too.

[Effect of idea]

As explained above, according to the alignment and winding device of this invention, the screw shaft for reciprocating the traverser is connected to the differential gear mechanism, and the differential gear mechanism is controlled by the output signal of the angle detector. A variable speed motor is connected to the differential gear mechanism, and a reference rotation speed for moving the traverser at a predetermined reference speed is input to the differential gear mechanism. Since the output rotation speed of the dynamic gear mechanism is configured to change continuously from the reference rotation speed, the rotation speed of the screw shaft changes at the same time as the traverser deviates from the intended position and the feeding angle of the linear body to the drum changes. Fine-tune the traverser's movement speed by increasing or decreasing
As a result, the position of the traverser, that is, the feeding angle of the filament with respect to the drum can be set quickly and accurately, and as a result, the filament can be wound stably and in an aligned manner.

Further, since the output rotational speed of the variable speed motor and the output rotational speed of the main motor are both connected to two input parts of the differential gear mechanism 17, the reciprocating movement of the traverser 22 is mainly performed by the main motor, and the output rotational speed of the variable speed motor is Since it is only necessary to correct the feed angle of the cable core, a motor with a very small capacity is required, and the moment of inertia (GD ² ) of the motor can be ignored, making it possible to perform high-precision control with a simple control device. Moreover, even if the cable core feed angle detection device etc. breaks down, it can be wound manually.Furthermore, when the traverser is reversed at the drum's collar plate, the traverser can be rapidly forwarded using a variable motor. can. Furthermore, a differential gear mechanism,
Since the constituent members such as the variable motor are commonly used in various technical fields, effects such as the ability to easily and inexpensively manufacture the entire aligning and winding device can be obtained.
