Description

  TECHNICAL FIELD The present invention relates to a method and an apparatus for manufacturing a wound filament article in which a filament having a circular cross section is wound around a flanged bobbin (hereinafter simply referred to as a bobbin) in a plurality of layers.

  When winding a linear object on a bobbin in multiple layers, the running position of the linear object is regulated using guide rolls and the like, and the pitch is axially fed from one end of the bobbin in the width direction to the other end. Traverse with and wrap the filaments in line, raise the layer to the upper layer at the position in contact with the collar at the end of the bobbin drum, and after raising the layer, reverse the direction of the traverse and move from the other end to one end Traverse to and repeat. Detecting the position at which the layer rises to the upper layer is important in determining the timing of reversing the traverse direction, and if this position is not determined, a gap may occur between the bobbin flange and the striated object, or the same The striated objects are superimposed on the rows, which may cause winding disturbance.

  As a method of detecting the rising position of the layer, Patent Literatures 1 and 2 disclose means for detecting the rising of the layer by contacting the linear object with a detector (sensor) or measuring the distance to the linear object. Patent Literature 3 discloses a means for detecting a rising of a layer based on a deviation between a speed of a traveling linear object (line speed) and a linear speed of a bobbin (reel).

Hereinafter, preferred embodiments of the present invention will be specifically described.
First, a manufacturing apparatus used in the method for manufacturing a wound filament article of the present invention will be described. FIG. 1 is a diagram showing an embodiment of the manufacturing apparatus of the present invention. As illustrated in FIG. 1, the manufacturing apparatus 100 according to the present embodiment includes feed rolls 120-1 and 120-2, a feed roll drive motor 130, a hollow pipe 140, a slide mechanism 150, a bobbin 160, and a control unit 170. And FIG. 1 shows an example of main components related to the present embodiment among the components included in the manufacturing apparatus 100 according to the present embodiment.

The feed rolls 120-1 and 120-2 are a pair of rolls that travel in the direction of the bobbin 160 with the filament 110 therebetween. Each of the feed rolls 120-1 and 120-2 may be driven by the feed roll drive motor 130, or one of the feed rolls 120-1 and 120-2 is driven by the feed roll drive motor 130. The other of the feed rolls 120-1 and 120-2 may be a driven roll that rotates based on one rotation. The feed rolls 120-1 and 120-2 have a mechanism for nipping using a screw or a spring (not shown) so that the sandwiched filaments 110 do not slip, and one or both surfaces have urethane rubber or the like. Rubber lining. Here, the linear object 110 may have a circular cross section orthogonal to the length direction.
The feed roll drive motor 130 is a second motor that rotationally drives one or both of the feed rolls 120-1 and 120-2 at a constant rotation. It is preferable that the feed roll drive motor 130 is a servo motor including a rotary encoder that detects a rotation speed (the number of rotations per unit time).
The hollow pipe 140 has a cylindrical shape, and is a guide member through which the filaments 110 are inserted and which guides the filaments 110 to the winding position of the filaments 110 on the bobbin 160. The hollow pipe 140 introduces the filaments 110 from one end and extends from the other end to regulate the traveling position. The hollow pipe 140 is fixed to the slide mechanism 150. Details of the internal structure of the hollow pipe 140 will be described later.
The slide mechanism 150 is composed of a combination of a feed screw and a stepping motor. The slide mechanism 150 enables the hollow pipe 140 to move from the center side of the bobbin 160 in the outer peripheral direction in accordance with the rising of the layered object 110. More specifically, when the slide mechanism 150 detects the operation in which the winding layer of the filament 110 is raised, the end of the hollow pipe 140 on the bobbin 160 side and the bobbin 160 on which the filament 110 is wound are formed. The hollow pipe 140 is moved outward from the center of the bobbin 160 by the diameter of the filament 110 so that the distance to the position is constant.
The bobbin 160 is a flanged bobbin having a cylindrical body and flat flanges at both ends of the body. The bobbin 160 is rotationally driven by a bobbin driving motor described later.

FIG. 2 is a diagram showing an example of the structure of the manufacturing apparatus 100 shown in FIG. As shown in FIG. 2, the manufacturing apparatus 100 further includes a bobbin driving motor 190 and a traverse mechanism 200.
The bobbin driving motor 190 is a torque motor for rotating the bobbin 160 for winding the filaments 110 at a constant tension or a servo motor (first motor) capable of setting a torque mode. A servo motor is preferably provided with a rotary encoder for detecting a rotation speed (the number of rotations per unit time). The bobbin 160 winds up the filamentary product 110, and the filamentous material winding body 180 is formed.
The traverse mechanism 200 is a mechanism for reciprocating the bobbin 160 in the axial direction of the bobbin 160. The traverse mechanism 200 is configured by a combination of a feed screw, a stepping motor, and the like.
The control unit 170 controls the feed roll drive motor 130, the slide mechanism 150, the bobbin 160, the bobbin drive motor 190, and the traverse mechanism 200. Details of the control performed by the control unit 170 will be described later.
The feed roll drive motor 130 and the bobbin drive motor 190 are sequence-controlled by the control unit 170, and the running speed of the filament 110, the winding tension, the timing of starting and stopping the traverse of the bobbin 160 (the winding angle described later). ), The traverse pitch, the movement pitch of the hollow pipe 140, and the like are controlled. In FIG. 1, the bobbin 160 rotates clockwise. In addition, the winding angle is set to 0 degree with reference to a position where one end of the filamentary object 110 is fixed to the bobbin 160, and indicates a counterclockwise angle position in FIG. Hereinafter, the angle of the bobbin shown in FIG. 1 is referred to as a winding angle.

The method for manufacturing a filament wound body of the present invention is a method for manufacturing a filament wound body in which a filament is aligned and wound in a plurality of layers on a flanged bobbin,
Fixing one end of the filament to one end of the trunk of the flanged bobbin,
From the start of winding, until the rotation angle of the flanged bobbin from the position of the flanged bobbin at the start reaches a predetermined angle, the flanged bobbin is driven to rotate without performing traverse to perform a predetermined winding. Winding the filament at a speed,
When the rotation angle reaches the predetermined angle, start the traverse,
Performing a winding process of winding the filament while keeping the adjacent filaments in contact with each other,
Based on a change in the rotation speed of a motor that rotationally drives the flanged bobbin, detecting an operation in which the winding layer of the filament is raised,
Upon detecting an operation in which the winding layer of the filamentous article has risen, the traverse is stopped,
The stop state of the traverse is maintained until the rotation angle of the flanged bobbin from the position of the flanged bobbin at the time of detecting the operation in which the winding layer of the filament is raised,
When the rotation angle reaches the predetermined angle, perform a restart process to reverse the direction of the traverse and restart the traverse,
Repeating the process from the winding process to the resuming process to align and wind a plurality of layers,
The above-mentioned predetermined angle is a manufacturing method of a filament wound object which is 250-360 degrees.

  FIG. 3 is a diagram illustrating an example of a state in which one end of the linear object 110 illustrated in FIG. 1 is fixed to the bobbin 160. As shown in FIG. 3, the bobbin 160 is provided at one end of its body 161 with a fixing part 162 for fixing one end of the filament 110, and one end of the filament 110 is fixed to the fixing part 162. ing.

Here, the layer rising operation is detected by a detection method based on a change in the rotation speed of the bobbin 160.
FIG. 4 is a diagram illustrating an example of how the rotation speeds of the feed roll drive motor 130 and the bobbin drive motor 190 of the manufacturing apparatus 100 illustrated in FIGS. The feed roll drive motor 130 rotates the feed rolls 120-1 and 120-2 at a constant rotation speed N1, and the bobbin drive motor 190 is controlled so that the winding tension is constant. When the layer rises, the winding radius r1 increases, so that the bobbin drive motor 190 reduces the rotation speed N2 of the bobbin 160 to keep the winding speed constant. The respective rotation speeds and the diameter d1 of the filamentary object 110 are input to the control unit 170, and by detecting the change, it is possible to detect an operation in which the layer has risen.

  The filament 110 has a circular cross section and is made of a resin monofilament, and is made of a thermoplastic resin such as ABS resin, polypropylene, nylon, polylactic acid, or polyethylene.

  The traverse mechanism 200 does not perform traversal from the start of winding the filament 110 until the rotation angle of the bobbin from the position of the bobbin 160 at the start of winding reaches a predetermined angle (250 to 360 degrees). , The bobbin 160 winds the filamentary product 110. The traverse mechanism 200 starts traversing when the rotation angle of the bobbin from the position of the bobbin 160 at the start of winding has reached a predetermined angle (250 to 360 degrees). The traverse mechanism 200 and the bobbin 160 perform a winding process for winding the filaments 110 while keeping the neighboring filaments 110 in contact with each other. By performing such a winding process, the filaments 110 are wound tightly together, so that the generation of a gap between the filaments 110 is suppressed, and the filaments 110 are separated from the gaps in the next winding layer. This has the effect of making it possible to form an aligned winding without getting in.

  The control unit 170 causes the traverse mechanism 200 to stop the traverse at the time when the winding of the filament 110 is completed to the other end which is not the one end of the winding start of the bobbin 160 and the operation of the filament rising is detected. Thus, the generation of a gap between the flange of the bobbin 160 and the striated material is suppressed, and the effect that the striated material 110 does not enter the gap in the next winding layer and enables the aligned winding is achieved.

The number of windings in each layer changes for each layer due to a diameter error of the filament 110, a deviation in the winding position of the bobbin 160 in the width direction when the bobbin 160 is wound, and the like. Therefore, in the winding method in which the number of windings is set, the filaments 110 may overlap in the same row at the end of the body of the bobbin 160, and when they occur for each layer, the regulation position of the filament 110 The deviation between the winding position on the bobbin 160 (ie, the position of the hollow pipe 140 in the manufacturing apparatus 100 shown in FIG. 1) and the winding position on the bobbin 160 becomes large, and the filaments 110 are not wound up at a predetermined position, which causes winding disturbance. .
FIG. 5 is a diagram showing an example of a state in which the position of the hollow pipe 140 shown in FIG. 1 and the winding position on the bobbin 160 are misaligned. As shown in FIG. 5, if a deviation occurs between the position of the hollow pipe 140 and the position where the filament 110 on the bobbin 160 is wound, the filament 110 is disturbed. . The present invention has an effect of suppressing the occurrence of the above-described problem even if the number of turns in each layer changes.

  The detection of the rising operation is performed using a change in the rotation speed of the bobbin drive motor 190 that drives the bobbin 160 to rotate. Therefore, it is not necessary to install a detector for detecting the rise of the layer, a distance sensor, and the like, so that the configuration of the device is simplified and the cost of the device is reduced.

  The control unit 170 causes the traverse mechanism 200 to maintain the traverse stop state until the rotation angle of the bobbin 160 becomes 250 to 360 degrees from the time when the operation of rising the layer is detected. Thereafter, when the rotation angle of the bobbin 160 from the point of detecting the operation of rising the layer becomes 250 to 360 degrees, the control unit 170 causes the traverse mechanism 200 to reverse (restart) the traverse direction and start (restart) the traverse (restart processing). . Accordingly, even if the layer goes up at an arbitrary angle of the bobbin winding angle, the control unit 170 causes the traverse mechanism 200 to start traversing at the set rotation angle. It is wound closely. Therefore, the generation of the gap between the filaments 110 is suppressed, and the filaments 110 do not enter the gaps in the next winding layer, so that an effect of enabling the aligned winding is achieved.

  Thereafter, by repeating the above-described winding process to the resuming process and performing the aligned winding of a plurality of layers, it becomes possible to manufacture a filament wound body 180 with an improved filling rate of the filament 110 on the bobbin 160. In addition, when the filaments 110 are unwound from the winding body, it is possible to avoid an entanglement or a cutting trouble caused by the filaments 110 biting into the lower layer filaments 110.

As shown in FIG. 3, the manufacturing method of the filament wound body 180 according to the present invention is such that the filament 110 is parallel to the rotation direction of the bobbin 160 on the fixing portion 162 provided at one end of the body 161 of the bobbin 160. It is preferable to fix so that
By fixing the filament 110 to a fixing portion 162 provided at one end of the body 161 of the bobbin 160 so as to be parallel to the rotation direction of the bobbin 160, the filament 110 at the beginning of winding and the flange of the bobbin 160 are fixed. This suppresses the generation of a gap with the wire, and prevents the filaments 110 from entering the gap in the next winding layer, thereby achieving an effect of enabling the aligned winding.

In the method for manufacturing the filament wound body 180 according to the present invention, the detection of the rising operation is performed when the rotation speed of the bobbin driving motor 190 for rotating the bobbin 160 changes by 2% or more. Is preferred.
By detecting that the layer has risen when the rotation speed of the bobbin drive motor 190 that drives the bobbin 160 to rotate changes by 2% or more, erroneous detection can be easily reduced.

In the method of manufacturing the wound filament article 180 of the present invention, it is preferable that the bobbin 160 be traversed.
As the traversing method, there are two methods, a method of traversing the bobbin 160 and a method of traversing a guide that guides the striated object 110 to the bobbin 160, and both methods can be adopted. As shown in FIG. 2, when the traverse mechanism 200 that traverses the bobbin 160 is provided, and the control unit 170 controls the traverse mechanism 200, the filament 110 is prevented from being bent and supplied to the bobbin 160. Is easier to do.

In the manufacturing method of the filament wound body 180 of the present invention, the winding speed of the filament 110 on the bobbin 160 is preferably 1 to 100 m / min.
When the winding speed is 1 m / min or more, productivity is not significantly reduced, and when the winding speed is 100 m / min or less, winding disturbance can be reduced.

FIG. 6 is a diagram illustrating an example of a guide that guides the linear object 110 illustrated in FIG. 1 to a winding position on the bobbin 160. As shown in FIG. 6, the method for manufacturing a filament wound body 180 of the present invention includes a hollow pipe 140 serving as a guide that regulates a winding position of the filament 110 on the bobbin 160. The distance X between the tip (the end on the bobbin 160 side) of the hollow pipe 140 for guiding the filament 110 to the winding position on the bobbin 160 and the position where the filament 110 is wound is 5 to 20 mm.
FIG. 7 is a diagram showing an example of a cross section of the hollow pipe 140 shown in FIG. The hollow pipe 140 shown in FIG. 6 preferably has an inner diameter D1 that is larger by 0.2 to 0.5 mm than the diameter d1 of the filament 110 and a wall thickness t that is 0.1 to 0.4 mm.

As described above, the guide of the hollow pipe 140 that regulates the winding position of the filament 110 is provided, and the end of the hollow pipe 140 from which the filament 110 is led out on the bobbin 160 side and the filament 110 are wound. When the distance from the position to be set is 5 mm or more, there is an effect of avoiding contact with the filament 110 already wound on the bobbin 160. In addition, since this distance is 20 mm or less, as shown in FIG. 5, the filaments 110 led out from the end of the hollow pipe 140 on the bobbin 160 side are wound before the bobbin 160 is wound around the bobbin 160. This has the effect of suppressing irregular movement in the direction from one end to the other end of the body. In particular, it is effective when the filament 110 has a small diameter of 1 to 2 mm and has flexibility. From these viewpoints, the distance is more preferably 7 to 15 mm.
Here, the position at which the filament 110 is wound is defined as the filament 110 (the first layer) of the bobbin 160 or the filament 110 wound around the trunk 161 of the bobbin 160 ( (Second layer or more).

  When the inner diameter D1 of the hollow pipe 140 is 0.2 mm or more larger than the diameter of the filament 110, an effect of reducing the resistance due to friction with the filament 110 is exerted. The positional deviation between the axial centerline of the hollow pipe 140 and the axial centerline of the filament 110 is suppressed, and the position regulation accuracy of the filament 110 is improved.

When the thickness t of the hollow pipe 140 is 0.1 mm or more, an effect of maintaining the cylindrical shape of the cross section and suppressing collapse of the pipe is exerted, and when the thickness t is 0.4 mm or less, the outer diameter of the hollow pipe 140 is reduced. D2 can be approximated to the diameter d1 of the filament 110, the filament 110 can be moved to the end of the body 161 of the bobbin 160, and the gap between the flange portion of the bobbin 160 and the filament 110 can be reduced. It has the effect of making it smaller.
Further, the hollow pipe 140 is preferably made of a material that is hard to be worn even when rubbed with the filament 110 made of metal, ceramic, fiber reinforced resin, or the like. When the material is a metal, stainless steel, a titanium alloy, duralumin, etc. are used. When the material is a ceramic, alumina, zirconia, etc. are used. When the material is a fiber reinforced resin, FRP (Fiber Reinforced Plastics) is used. ), CFRP (Carbon Fiber Reinforced Plastics), and the like. It is preferable to bevel the inner corner of the hollow pipe 140 so as not to cause abrasion on the filament 110 due to contact with the filament 110.

In the manufacturing method of the filament wound body 180 of the present invention, it is preferable that a rectangular object having a width smaller than the outer diameter D2 of the hollow pipe 140 is connected to the outside of the hollow pipe 140.
FIG. 8 is a diagram showing an example of a state where a rectangular object is connected to the outside of the hollow pipe 140 shown in FIG. As shown in FIG. 8, a rectangular object 210 having a width B smaller than the outer diameter D2 of the hollow pipe 140 is connected to the outside of the hollow pipe 140. Thereby, the rigidity of the guide of the hollow pipe 140 can be further improved. Thereby, the deflection of the tip of the hollow pipe 140 caused by the vibration generated by the filament 110 traveling inside the hollow pipe 140 is suppressed, and even if the winding position of the filament 110 is shifted, the hollow The bent or broken pipe 140 can be prevented. In addition, since the width of the rectangular object 210 is smaller than the outer diameter of the hollow pipe 140, there is an effect that the linear object 110 can be moved to the end of the body of the bobbin 160.
The rectangular object 210 is preferably connected to the entire length of the guide of the hollow pipe 140.

  In the manufacturing method of the filament wound body 180 of the present invention, the hollow pipe 140 moves by the diameter of the filament 110 when the layered operation is detected, and the hollow pipe 140 that leads the filament 110 is moved. It is preferable to keep the distance between the end on the bobbin 160 side and the position on the bobbin 160 where the filament 110 is wound up. When the distance is kept constant, an effect of suppressing the abrasion of the filament 110 due to contact between the end of the hollow pipe 140 on the bobbin 160 side and the filament 110 is exerted.

The manufacturing method of the filament wound body 180 of the present invention is a method of manufacturing a filament wound body in which the filament is aligned and wound in a plurality of layers on a flanged bobbin,
Fixing one end of the filament to one end of the trunk of the flanged bobbin,
From the start of winding, until the rotation angle of the flanged bobbin from the position of the flanged bobbin at the start reaches a predetermined angle, the flanged bobbin is driven to rotate without performing traverse to perform a predetermined winding. Winding the filament at a speed,
When the rotation angle reaches the predetermined angle, start the traverse,
Performing a winding process of winding the filament while keeping the adjacent filaments in contact with each other,
Count the number of windings in each layer of the striate,
The length from one end to the other end of the trunk of the flanged bobbin is divided by the diameter of the filament to calculate a predicted number of windings in each layer,
When the counted number of windings is a predetermined number of times less than the predicted number of windings, the winding speed of the filament is reduced by up to 95%,
When the counted number of windings reaches the predicted number of windings, the traverse is stopped,
Maintaining the stopped state of the traverse until the rotation angle of the flanged bobbin reaches the predetermined angle from the position of the flanged bobbin at the time when the counted number of windings reaches the predicted number of windings,
When the rotation angle reaches the predetermined angle, perform a restart process to reverse the direction of the traverse and restart the traverse,
Until the counted number of windings reaches the predetermined number, maintaining a reduction in the winding speed of the filamentous material,
Repeating the winding process from the process of maintaining the reduction of the speed of winding of the filaments to perform aligned winding of a plurality of layers,
The predetermined angle is 250 to 360 degrees, and the predetermined number of times is 1 to 5 times.

The winding number of each layer of the filament 110 is calculated by dividing the length from one end to the other end of the body of the bobbin 160 by the diameter of the filament 110, and a predetermined winding speed A (for example, The filaments 110 are wound by the rotation speed of the bobbin 160), the number of windings on each layer of the filaments 110 is counted, and the counted number of windings is 1 to 5 times less than the estimated number of windings. Then, by reducing the winding speed of the filament 110, the difference between the rotation speed of the feed rolls 120-1 and 120-2 and the rotation speed of the bobbin 160 due to rapid deceleration can be suppressed. An effect of preventing an overload on the filament 110 and a yarn breakage due to an increase in winding tension caused by a difference in the number is obtained.
If the cross section of the filament 110 is not a perfect circle, the average value of five measurements of the fiber width may be used as the diameter of the filament 110.
In addition, when the winding speed is high, winding is progressing from the time when the layer rise is detected to the time when the traverse reversal is started, and the traverse cannot be started at the set winding angle. There is a risk of disorder. By decelerating when the layer rises, there is an effect of preventing such a trouble.
The deceleration rate is set based on the winding speed when the layer rises. That is, if the winding speed A is low, the deceleration rate can be set low, and if it is high, it can be set high.

  After the traverse reversal is performed and the winding speed is reduced to 1 to 5 times after the traverse reversal and then the winding speed is increased to the speed A, the feed roll 120 accompanying the rapid increase in speed is increased. -1, 120-2 and the rotation speed of the bobbin 160 can be suppressed, and the effect of preventing the fluctuation of the winding tension and the separation of the filament 110 from the bobbin 160 (that is, the winding position is shifted) can be prevented. Play.
