DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filament winding device.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 4, the above-mentioned yarn winding device employs a spindle 2 as a rotating body for rotating the bobbin 1 around a horizontal axis O, and a yarn winding on the bobbin 1. A predetermined number of yarn guides 4 for guiding a yarn as a body are provided on the apparatus frame 3 so as to be vertically fixed to each other, and [B] the final yarn guide 4 on the lowermost side in the yarn feeding direction. Is set above the spindle 2 and [C] a traverse mechanism 11 that reciprocates the yarn portion below the final yarn guide in the axial direction of the spindle with the rotation of the spindle 2 It was provided on the frame 3 so that the yarn [D] was wound on the bobbin 1 at a set twill angle and a set winding width.

In the means for winding the yarn to the set winding width on the bobbin 1, the length of the yarn path between the final yarn guide 4 and the bobbin 1 is set at the center of the bobbin portion corresponding to the set winding width in the axial center direction. There is a difference between the case where the yarn is wound around the portion and the case where the yarn is wound around both ends of the bobbin portion.

That is, the swing angle of the yarn (that is, the yarn path extending from the final yarn guide to one end of the bobbin in the axial direction) and the yarn path extending from the final yarn guide to the other end of the bobbin in the axial direction. Angle between the leading yarn path and the other side)
When the yarn is wound at a constant speed, the yarn tension fluctuates with the winding of the yarn. And the larger the swing angle is, the more the tension of the yarn fluctuates, which has a bad influence on the yarn such as yarn breakage and elongation.

Therefore, in the conventional structure, the above [A]-
In addition to the configuration of [D], the configuration was as follows.

[E] The tension fluctuation suppressing means 12 for the yarn is provided on the apparatus frame 3 and [F] The tension fluctuation suppressing means 1 is provided.
2, a yarn guide 4 for regulating the yarn path is provided on the upper side of the final yarn guide in the yarn feeding direction, and between the final yarn guide 4 and the yarn guide 4 for regulating the yarn path, The dancing arm 13 with the yarn guide 4 is rotatably provided around the horizontal axis P, and [G] a detector for detecting the amount of rotation of the dancing arm 13 around the horizontal axis is provided.
A control device is provided for controlling the number of rotations of the electric motor for driving the spindle.

The dancer guide 17 has a structure in which the dancing arm 13 is rotatably provided on the apparatus frame 3 around the horizontal axis.

The means for detecting the yarn tension via the dancing arm 13 has a limit in its detection range, and the detection range is usually limited by other detection means. [H] The swing angle is 60
It is set below the degree.

When the swing angle is limited to 60 degrees or less, the vertical distance from the bobbin 1 to the final yarn guide 4 is limited, and the swing angle is determined by the set winding width and the swing angle. That is, the vertical interval is equal to or longer than a predetermined length.

The above-mentioned predetermined length is considerably long in this type of winding device. When a plurality of winding mechanisms 16 including the spindle 2 and the thread guide 4 are provided on the device frame 3 in the vertical direction, the uppermost winding device is provided. The yarn guide of the take-up mechanism is located at a height of 2 m or more from the floor, which is a height at which the threading operation by the operator is difficult.

Therefore, in the conventional structure, the number of stages in which the winding mechanism 16 is installed vertically with respect to the apparatus frame 3 is limited to a small number of stages, and in many cases, only one stage is provided as in the conventional structure shown in FIG. .

[0012]

According to the above-mentioned conventional structure, the number of vertically installed steps of the winding mechanism including the spindle and the thread guide with respect to the apparatus frame 3 is limited to a small number of steps, and in many cases, the number of steps shown in FIG. Since only one stage is provided as in the conventional structure shown in the figure, when a large number of winding mechanisms are provided in the device frame, they must be arranged side by side in a horizontal direction, and the overall length of the device is increased, and the installation space is increased. There were problems such as becoming.

An object of the present invention is to provide a structure in which a winding mechanism including a rotating body such as a spindle and a yarn guide is provided in a large number on an apparatus frame.
It is an object of the present invention to provide a winding device for a filament which has advantages such as a reduced installation space.

[0014]

The constitution, operation and effect of the invention according to claim 1 are as follows.

[Structure] A rotating body for rotating a bobbin about a horizontal axis and an arbitrary number of thread guides for guiding a thread to the bobbin are provided on an apparatus frame. The position of the lowest thread guide in the feed direction of the filament is set above the rotating body, and the filament is wound on the bobbin to a set winding width,
A predetermined number of thread guides including the lowermost thread guide,
The rotating body is configured to be movable up and down so as to be switchable between a retracted posture in a lowered state and a winding guide operation posture in an ascended state.

[Operation] [a] The worker can perform threading work or the like with a predetermined number of thread guides including the lowermost thread guide set in the storage position.

In the retracted position, the predetermined number of thread guides are in a lowered state. Therefore, even if the number of installation steps in the vertical direction with respect to the apparatus frame of the winding mechanism including the rotating body and the thread guides is increased, the uppermost winding step is performed. For example, the yarn guide of the take-up mechanism can be arranged at a low place of 2 m or less from the floor surface where the operator can reach.

In the retracted position, the swing angle (that is, the yarn path extending from the yarn guide on the lowermost side in the feed direction of the filament to one end in the axial direction of the bobbin portion corresponding to the set winding width; The angle between the yarn guide from the yarn guide on the lowermost side in the feed direction and the other end in the axial direction of the bobbin portion with respect to the other side is large.

[B] When the thread passing operation is completed, the predetermined number of thread guides are set to the take-up guide action position, and the bobbin is rotated by the rotating body so that the swing angle is smaller than that in the retracted position. While rotating around the center, the thread is guided by an arbitrary number of thread guides, and wound on a bobbin lower than the lowermost thread guide side to a set winding width.

[C] In the means of winding a yarn to a set winding width on a bobbin, the yarn tension fluctuates when the yarn is wound at a constant speed, and the yarn tension fluctuates greatly as the swing angle increases. Therefore, there is a problem that the yarn has an adverse effect such as yarn breakage or elongation. Therefore, this type of winding device generally responds by providing a tension variation suppressing means for the filament.

In the structure of the first aspect, as in the above [B],
Since the winding is performed in a state where the swing angle is set to be small, it is easy to accurately detect the tension of the filament by the tension variation suppressing means and to perform the regulation of the variation of the tension of the filament based on the detection result. It becomes easier to avoid.

[D] That is, even if the number of installation stages of the winding mechanism with respect to the apparatus frame in the vertical direction is increased, it is easy to accurately control the fluctuation of the tension of the filament.

[E] As described in [A] and [D] above, the number of installation stages of the winding mechanism in the vertical direction with respect to the apparatus frame can be increased, so that the entire length of the apparatus frame can be reduced.

[Effect] Therefore, although a structure in which a number of winding mechanisms including a rotating body and a thread guide are provided on the apparatus frame, the overall length of the apparatus can be shortened, and the installation space can be reduced. It has been possible to provide an apparatus for winding a filament.

The structure, operation and effect of the invention according to claim 2 are as follows.

[Structure] A rotating body for rotating a bobbin about a horizontal axis and an arbitrary number of thread guides for guiding a thread to the bobbin are provided on an apparatus frame. The position of the lowest thread guide in the feed direction of the filament is set below the rotating body, and the filament is wound on the bobbin to a set winding width,
The rotating body is configured to be able to move up and down with respect to the yarn guide, and is configured to be switchable between a retracted posture in a lowered state and a winding operation posture in an ascended state.

[Operation] [f] The worker can perform threading work or the like with the rotating body set in the storage position.

In the retracted position, the rotating body is in the lowered state. Therefore, even if the number of stages of the winding mechanism composed of the rotating body and the thread guide and the like in the vertical direction with respect to the apparatus frame is increased, the rotation of the uppermost winding mechanism is maintained. For example, the body can be placed at a low place of 2 m or less from the floor surface where the worker can reach.

In the retracted position, the swing angle is large.

[G] When the thread passing operation is completed, the bobbin is rotated around the horizontal axis by the rotating body while the rotating body is set to the winding operation posture and the swing angle is smaller than that in the retracted posture. At the same time, the thread is guided by an arbitrary number of thread guides, and wound on a bobbin above the lowermost thread guide to a set winding width.

[H] According to the structure of claim 2, claim 1
Almost the same operation as the operation [c] by the above configuration can be obtained.

That is, since the thread is wound in a state where the swing angle is set to a small value as in [g], it is easy to accurately control the fluctuation of the tension of the thread, and it is possible to prevent the thread from breaking or stretching. The problem of adverse effects can be easily avoided.

As a result, substantially the same operations as the operations [d] and [e] according to the first aspect can be achieved.

[Effect] Therefore, although a structure in which a number of winding mechanisms including a rotating body and a thread guide are provided on the apparatus frame, the overall length of the apparatus can be shortened and the installation space can be reduced. It has been possible to provide an apparatus for winding a filament.

The construction, operation and effect of the invention according to claim 3 are as follows.

[Structure] In the structure of the invention according to claim 1 or 2, the yarn from the yarn guide at the lowermost side in the feeding direction of the filament to one end in the axial direction of the bobbin corresponding to the set winding width. The swing angle formed by the path and the yarn path from the yarn guide on the lowest side in the feed direction of the filament to the other end in the axial direction of the bobbin portion with respect to the other side is 120 degrees in the storage posture. A minimum vertical distance between the rotating body and the lowermost yarn guide is set so that the rotation angle does not exceed the degree, and the swing angle is less than 5 degrees in the winding operation posture or the winding guide operation posture. In order to prevent this, the maximum distance between the rotating body and the lowermost yarn guide in the vertical direction is set.

[Operation] In addition to the same operation as the operation according to the first or second aspect, the following operation can be obtained.

If the swing angle exceeds 120 degrees, the amount of change in the vertical distance between the rotating body and the yarn guide on the lowermost side in the feed direction of the thread is too large.
Storage position and winding operation position (or winding guide operation position)
In this case, there is a problem that thread breakage or thread elongation of the filamentous body is liable to occur, but according to the configuration of claim 2, since the swing angle is set to 120 degrees or less, the above problem is solved. Can be avoided.

The smaller the swing angle is, the smaller the fluctuation of the tension of the thread can be. However, if the swing angle is less than 5 degrees, the up-down distance becomes too large in the winding operation posture (or the winding guide operation posture), and the apparatus is moved vertically. There is a problem that becomes large.

On the other hand, according to the configuration of claim 2, since the swing angle is set to 5 degrees or more, the above problem can be avoided.

[Effects] Therefore, in addition to the same effects as the effects of the configuration of claim 1 or 2,
The device can be made more compact, and the filament can be wound up smoothly.

[0042]

This winding device includes a plurality of spindles 2 (corresponding to rotating bodies, which are driven to rotate by an electric motor M2) for rotating the bobbin 1 about the first horizontal axis O.
The plurality of guide portions 5, which are arranged in the up-down direction and the front-rear direction (the left-right direction on the paper surface), and each include a plurality of guide rollers 4 (corresponding to a thread guide), are brought into a state corresponding to the plurality of spindles 2 respectively. Side by side in the vertical and front-rear directions,
For each guide portion 5, the position of the guide roller 4 (hereinafter, referred to as "final guide roller 4") which is the lowest in the feed direction of the thread (corresponding to a thread-like body) among the plurality of guide rollers 4 is referred to as the spindle 2 The bobbin 1 is configured to wind the yarn from a yarn supply unit (not shown) around each bobbin 1.

That is, the first device frame portion 6 is lowered with respect to the second device frame portion 7 to set the storage position, and is raised to set the winding guide operation position.

As shown in FIG. 3, a traverse mechanism 11 for reciprocating a thread portion between the bobbin 1 and the final guide roller 4 in the axial direction of the spindle 2 with the rotation of the spindle 2 is provided by a first mechanism. The yarn is wound on the bobbin 1 via the traverse mechanism 11 to the set twill angle and the set winding width.

As described above, in the means for winding the yarn on the bobbin 1 to the set winding width, the length of the yarn path between the final guide roller 4 and the bobbin 1 is changed to the bobbin portion corresponding to the set winding width. And the case where the yarn is wound at both ends of the bobbin portion.

That is, the yarn swing angle α (that is, the yarn path L1 extending from the final guide roller 4 to one end of the bobbin portion in the axial direction) and the final guide roller 4 extending from the axial guide direction of the bobbin portion An angle formed between the yarn path L2 reaching the other end and the other side with respect to the other side), and when the yarn is wound at a constant speed, the tension of the yarn fluctuates with the winding. And the swing angle α
The larger the value is, the more the tension fluctuates and adversely affects yarn such as yarn breakage and elongation.

Therefore, in addition to the above-mentioned structure, a tension fluctuation suppressing means 12 for the yarn is provided in the first apparatus frame portion 6.

In constituting the tension fluctuation suppressing means 12,
A guide roller 4 for regulating the yarn path is provided on the upstream side of the final guide roller 4 in the yarn feeding direction.
A dancing arm 13 with a guide roller 4 for the yarn is rotatably provided around a second horizontal axis P along the axis of the spindle 2 between the yarn and the guide roller 4 for regulating the yarn path. 13 is provided with a detector 14 for detecting the amount of rotation around the second horizontal axis P, and a control device 15 for controlling the number of rotations of the spindle driving electric motor M2 based on the detection result.

The dancer guide 17 has a structure in which the dancing arm 13 is rotatably provided on the apparatus frame 3 around the horizontal axis.

[Preparation work before starting] The threading work is performed when the first device frame part 6 is lowered and the guide rollers 4 and the tension fluctuation suppressing means 12 of each guide part 5 are in the retracted posture.

In this retracted position, the uppermost guide roller 4 and the tension fluctuation suppressing means 12 are located at a low place of 2 m or less from the floor where the operator can reach.

Therefore, the operator can perform the threading operation without using a stepladder or the like. In the retracted position, the swing angle α
Is in a large state.

[Operation after Starting] When the thread passing operation is completed,
The electric motor M1 for raising and lowering is driven to set the guide rollers 4 and the tension fluctuation suppressing means 12 of each guide portion 5 to the above-described winding guide action posture, and the bobbin is set in a state where the swing angle α is smaller than the retracted posture. Wind the yarn.

That is, the spindle driving electric motor M2
Drives the bobbin 1 via the spindle 2 to the first horizontal axis O
And the yarn is guided by a plurality of guide rollers 4. With the rotation of the spindle 2, the yarn portion between the bobbin 1 and the final guide roller 4 is moved through the traverse mechanism 11 to the axis of the spindle 2. It is reciprocated in the center direction and wound up on the bobbin 1 below the final guide roller 4 to the set twill angle and the set winding width.

At the time of this winding, the tension fluctuation suppressing means 12
Thus, the fluctuation of the tension of the yarn is suppressed and adjusted, and the yarn breakage or the like is prevented.

If the swing angle α at the time of winding is large, there is a problem that it is difficult to detect the tension of the yarn with the dancing arm 13. Since the yarn is wound on the bobbin in a reduced state, the above-described problem can be avoided.

The vertical interval between the spindle 2 and the final guide roller 4 is set so that the swing angle α does not exceed 120 degrees in the retracted position, and the swing angle α is set to the winding guide action position. The maximum distance between the spindle 2 and the final guide roller 4 in the vertical direction is set so as not to be less than 5 degrees.

For example, the length of the device can be reduced to 1/2 to 1/4 as compared with a structure in which the winding mechanism 16 is provided in one upper and lower stages on the apparatus frame 3 (the number of winding mechanisms 16 is the same).

Further, even if the winding width changes and the vertical distance changes, the swing angle α can be changed and adjusted by raising and lowering the first device frame portion 6 by the lifting mechanism 8.

[Another Embodiment of the First Embodiment] Even if the guide roller 4 of the winding mechanism 16 is not moved up and down, only the guide roller 4 located at a high place is moved up and down. Good.

That is, the "predetermined number" of the guide rollers 4 is configured so as to be able to move up and down with respect to the spindle 2.
All the guide rollers 4 may be configured to be able to move up and down with respect to the spindle 2, and only some of the guide rollers 4 located at a higher position may be configured to be able to move up and down with respect to the spindle 2. It is.

[Second Embodiment] Although not shown, the second embodiment has substantially the same structure as that of the first embodiment, and a plurality of spindles for rotating the bobbin around the horizontal axis are mounted on the apparatus frame in the up-down direction and the front-back direction. And a plurality of guide portions comprising a plurality of guide rollers are arranged side by side in the up-down direction and the front-rear direction on the apparatus frame in a state respectively corresponding to a plurality of spindles. Of the guide rollers, the position of the lowermost guide roller in the yarn feeding direction is set below the spindle, and the yarn is wound on each bobbin to the set winding width, and the spindle of each guide portion is The guide roller is configured to be movable up and down so as to be switchable between a retracted posture in a lowered state and a winding operation posture in an ascended state.

The present invention can be applied to a case where a fiber or a tape is wound in addition to a yarn, and these are collectively referred to as a thread.

The number of the guide rollers and the number of the winding mechanisms 16 are not limited to the numbers in the above embodiment, but can be changed as appropriate.

The number of installation stages of the winding mechanism in the up-down direction and the front-rear direction is not limited to the number in the above embodiment, but can be changed as appropriate.
