Description

  The present invention relates to an apparatus for manufacturing a resin-impregnated fiber bundle wound body such as a fiber reinforced plastic (FRP) container.

  FRP is a composite material in which resin is reinforced with reinforcing fibers, and it is lighter than metal materials such as iron and aluminum, but can exhibit strength and rigidity equivalent to or higher than those of metal materials. Widely used.

  In FRP production, in the raw material stage, it is common that the fiber bundle is composed of a plurality of single fibers and a liquid resin, and the fiber bundle and the resin are combined by various production means. It is necessary to make it.

  The present invention relates to a wound body molded product based on a filament winding (FW) method. The FW method is a method of winding a fiber bundle impregnated with a resin around a mandrel that rotates on a fixed shaft, and is widely used because of its excellent physical properties such as strength and rigidity, and high productivity and easy mass production. This is the method used.

  During the manufacturing process of the FW method, when the fiber bundle is unwound from the fiber bundle bobbin wound and wound, the fiber bundle may be twisted (twisted) at the folded end.

  In the example of the prior art shown in FIG. 5, guides (vertical combs 110 and 210, eyelets 310) for restricting the fiber bundle 1 to pass through a specified position are provided. When it is tape-shaped, that is, when the width is wide and the thickness is thin, when the reaction force F acts in the fiber bundle width direction by contact with the guides, the fiber bundle is folded or twisted as shown in FIGS. May easily occur.

  This results in several adverse effects. First, an example has been reported in which the strength of the product is reduced when the fiber bundle is wound in a twisted state. Second, when the fiber bundle is twisted or bent, the width of the fiber bundle varies, which may cause gaps or resin reservoirs in the product, which may reduce product quality and cause variations.

  From the above, an apparatus capable of winding a resin-impregnated fiber bundle without causing twisting and folding has been desired.

  Hereinafter, the present invention will be described in detail.

<First Embodiment>
An apparatus for manufacturing a resin-impregnated fiber bundle wound body according to a first embodiment of the present invention will be described with reference to FIGS. 1a and 1b. In this manufacturing apparatus, the unwinding part 100 that feeds the fiber bundle from the bobbin, the winding head moves freely with respect to the mandrel rotating on the fixed shaft, and the product side is wound by winding the fiber side onto the mandrel. Between the unwinding part 100 and the guide part 200 provided with the guide member which guides the fiber bundle drawn out from the unwinding part to the winding part between the unwinding part 100 and the winding part 300 is comprised. Is done.

<Outline of guide member>
“˜Guide” or “Guide member” (hereinafter referred to as, for example, the C—H guide 102 or the C—V guide 103) in the text refers to the fiber bundle bobbin 101. It is a generic term for members that are used in contact with the fiber bundle 1 that has been fed out from and arranged for the purpose of guiding and winding the mandrel while changing its height and direction without giving unnecessary twisting or folding. . As shown in FIG. 6 as examples 11, 12, 13, and 14 of general guide members, the shape is a rod-like member elongated in one direction, and the long elongated axis (center axis 21) is a rotation axis. A rotationally symmetric shape is preferred. More specifically, it may be a shape (11) that is uniform in the direction of the central axis 21 or a shape that includes a portion that changes continuously or discontinuously (12, 13, 14).

  The guide member is disposed so that the central axis 21 and the traveling direction of the fiber bundle 1 are substantially orthogonal to each other, and the fiber bundle 1 travels while being in contact with the rotationally symmetrical outer peripheral surface. It is possible to restrict the position of 1 to a predetermined position. Preferably, the width direction of the fiber bundle 1 is aligned with the direction of the central axis 21 of the guide member (guide member 11 in the illustration of FIG. 9) so that the ideal passing state of the fiber bundle 1 is shown in FIG. By running, a reaction force can be applied not in the width direction of the fiber bundle 1 but in the thickness direction, and as a result, the fiber bundle can be hardly twisted or folded.

  As for a portion where the fiber bundle 1 contacts, the fiber bundle 1 may be run without giving excessive resistance by allowing the fiber bundle 1 to follow the fiber bundle 1 as a roller member that can rotate around the central axis, or at the center. As a fixed guide bar member that cannot rotate around the axis, a resistance force may be applied to the fiber bundle 1 to run. These can be selected according to the predetermined purpose of each part of the device.

<Unpacking section>
The unwinding unit 100 includes a fiber bundle bobbin 101, a CH guide 102 disposed on the downstream side of the fiber bundle bobbin 101 so that the rotation axis of the fiber bundle bobbin 101 coincides with the axial direction, and the fiber bundle bobbin 101. And a CV guide 103 disposed so that the axial direction is substantially orthogonal to both the rotation axis and the fiber bundle traveling direction.

<Fiber>
As the reinforcing fiber used in this production method, various kinds of reinforcing fibers such as inorganic fibers such as glass fibers generally used as reinforcing fibers for FRP, organic fibers such as carbon fibers and aramid fibers, or a plurality of kinds thereof are used. Can be used in combination. Preferably, glass fiber, aramid fiber, or carbon fiber is used from the viewpoint of strength and rigidity. More preferably, a tape-shaped untwisted fiber bundle bobbin is used. The tape-shaped fiber bundle refers to a fiber bundle having an aspect ratio of 10 or more, which is a value obtained by dividing the width of the fiber bundle by the thickness of the fiber bundle. Alternatively, a prepreg (tow prepreg) wound around a bobbin after a resin bundle is impregnated in a semi-cured state in advance may be used, or a fiber bundle not impregnated with resin may be used.

<CV guide / CH guide>
Regarding the number of C—H guides 102 and C—V guides 103 responsible for guiding the fiber bundles 1 drawn out from the fiber bundle bobbins 101 to the guide unit 200 described later, the viewpoint of layout constraints and economics of the manufacturing equipment From this point of view, an optimum number is selected for each manufacturing apparatus. Specifically, it is preferable to provide two or more of each because the fiber bundle 1 can be fed out stably. Although there is no particular limitation on the diameter of the portion of the C-H guide 102 and the C-V guide 103 that the fiber bundle 1 contacts, it is preferable to use a guide in the range of 1 to 50 mm. There are no particular restrictions on the guide material and the surface treatment, and various guide members can be applied in accordance with the purpose of each manufacturing apparatus.

<Effects of guide structure of unraveling section>
When the fiber bundle bobbin wound up by traversing is unwound, the fiber bundle 1 is unwound while reciprocating over the entire length of the bobbin in the fiber bundle width direction, that is, in the axial direction of the fiber bundle bobbin 101. There are characteristics to be deceived. With respect to this characteristic, it is preferable to set the axial length of the C-H guide 102 to be equal to or greater than the total length of the fiber bundle bobbin because the fiber bundle 1 can be reliably prevented from coming off from the C-H guide 102. Further, by disposing the CV guide 103 whose axial direction is orthogonal to both the axial direction of the fiber bundle bobbin 101 and the fiber bundle traveling direction, the CV guide 103 is closest to the fiber bundle bobbin 101. The position of the arranged guide serves as a fulcrum for reciprocating movement of the fiber bundle 1 by traversing, and reciprocating movement due to traversing can be suppressed in a process downstream of the guide that has become the fulcrum of reciprocating movement.

  FIG. 10a shows a range 400 in which the fiber bundle can traverse and move in FIG. 10b, and FIG. 10b shows a range 400 in the prior art in which the fiber bundle can traverse and move.

  In the prior art, the range 400 in which the traverse movement can be performed is wide, and the position regulating means for the fiber bundle 1 such as the vertical comb 110 and the eyelet 310 is included inside the range 400 in which the traverse movement can be performed. That is, it is inevitable that the fiber bundle 1 comes into contact with the position regulating means, and the position of the fiber bundle 1 is regulated by applying a force in the fiber bundle width direction, so that twisting and folding due to traversing movement are likely to occur.

  On the other hand, in the present invention, the traverse movement occurs with the guide located closest to the fiber bundle bobbin 1 among the CV guides 103 as a fulcrum, so the process is downstream of the guide that is the fulcrum of reciprocation. There is no guide member that can apply force in the width direction of the fiber bundle 1, and it is possible to reliably prevent unnecessary twisting and folding of the fiber bundle 1 due to traversing movement.

<Winding part>
Next, the winding part 300 for winding the fiber bundle around the mandrel will be described first.

  The winding unit 300 includes a mandrel 301 that is an object to be wound, a winding head 302 that moves freely with respect to the mandrel 301, and an FH guide that is arranged so that the axis of rotation of the mandrel 301 coincides with the axial direction. 306 and an FV guide 305 arranged so that the axial direction is substantially orthogonal to both the axial direction of the FH guide 306 and the fiber bundle traveling direction.

  Since the F-H guide 306 and the F-V guide 305 are fixed to the winding head 302, the winding head 302 maintains the mutual positional relationship between the F-H guide 306 and the F-V guide 305. Can be freely moved with respect to the mandrel 301.

<Outline of operation of winding part>
In the winding unit 300, the fiber bundle 1 guided from the guide unit 200 described later passes through the FV guide 305 and the FH guide 306 fixed to the winding head 302 and is fixed in space. It is wound around a mandrel 301 that can rotate on a shaft. The winding head 302 is moved in the mandrel while moving its position freely, for example, in the moving direction 303, in accordance with the fiber bundle winding amount and winding angle designed in advance according to the required characteristics of the product. The resin impregnated fiber bundle wound body 304 is manufactured by performing winding on 301.

<FH guide / FV guide>
The FH guide 306 can be wound while maintaining the substantially parallel positional relationship between the surface of the mandrel 301 and the fiber bundle 1 by disposing the FH guide 306 on the side closest to the mandrel 301. By adopting this arrangement, it is difficult for force to act in the fiber bundle width direction even during winding, and twisting and folding of the fiber bundle 1 can be prevented. Further, the FV guide 305 is disposed on the side farthest from the mandrel 301, that is, the side closest to the guide unit 200, so that the winding head 302 moves greatly along the moving direction 303. As shown in the ideal passing state in FIG. 9, the direction of the reaction force F acting on the fiber bundle 1 can be the fiber bundle thickness direction, not the fiber bundle width direction. This is desirable because it does not occur.

  As for the numbers of the F-H guides 305 and the F-V guides 306, the optimal number for each manufacturing apparatus is selected from the viewpoint of layout constraints of manufacturing equipment and the viewpoint of economy. Specifically, it is preferable to provide two or more of each because the fiber bundle 1 can be fed out stably. In the FH guide 305 and the FV guide 306, the diameter of the portion where the fiber bundle 1 contacts is not particularly limited, but a guide in the range of 1 to 50 mm is used. preferable. There are no particular limitations on the guide material and the surface treatment mode, and various guide members suitable for the purpose of each manufacturing apparatus can be applied.

<Induction section>
The guide part 200 provided between the unwinding part 100 and the winding part 300 is configured to include at least an M guide 201 arranged so that the axial direction is substantially orthogonal to the fiber bundle traveling direction.

<M guide>
Regarding the axial direction of the M guide 201 arranged to guide the fiber bundle 1 from the unwinding portion 100 to the winding portion 300, the axial direction of the guide located closest to the guiding portion among the F-V guides 306, and M It is important to have a configuration in which the axial direction of the guide located closest to the winding portion of the guide 201 matches. By applying this arrangement, even if the winding head 302 moves greatly along the moving direction 303, the reaction force acting on the fiber bundle 1 as shown in the ideal passing state in FIG. Since the direction of F can be not the fiber bundle width direction but the fiber bundle thickness direction, it is desirable for the fiber bundle 1 to avoid unnecessary folding or twisting.

  What is important in the implementation of the present invention is the relationship between the axial direction of the CH guide 102 and the CV guide 103 with respect to the axial direction of the fiber bundle bobbin 101, and the FH guide with respect to the axial direction of the mandrel 301. The relationship between the axial direction of 306 and the axial direction of the F-V guide 305 and the axial direction of the M guide 201 is not limited to the embodiment shown in FIGS. 1a and 1b. As shown, the axial direction of the fiber bundle bobbin 101 and the axial direction of the mandrel 301 may be orthogonal to each other.

  About the number of M guides 201, the optimal number for each manufacturing apparatus is selected from the viewpoint of layout restrictions of manufacturing equipment and the viewpoint of economy. Specifically, it is preferable to provide two or more fibers because the fiber bundle 1 can be stably fed out. Although there is no restriction | limiting in particular about the diameter of the site | part which the fiber bundle 1 contacts in the M guide 201, It is preferable to use the guide which exists in the range of 1-50 mm. There are no particular restrictions on the guide material and the surface treatment, and various guide members can be applied in accordance with the purpose of each manufacturing apparatus.

<Reciprocal relationship of each guide member arrangement>
In addition, the F-H guide 306 is positioned closest to the guide portion 200 and the F-H guide 306 of the M guide 201, the C-H guide 102, and the C-V guide 103 is aligned in the axial direction. Among the guides to be arranged, the guide located closest to the winding portion 300 is arranged on a plane including both of the guides and the fiber bundle 1 traveling on the guides. preferable.

  FIG. 11 shows an example in which the traveling directions of the fiber bundle 1 immediately before / immediately before twisting of the fiber bundle 1 are both located on the same plane, and FIG. 12 shows immediately before / immediately after twisting of the fiber bundle 1. The comparative example in which the traveling direction of the fiber bundle 1 is not located on the same plane is shown. By applying this arrangement, the traveling direction of the fiber bundle 1 and each guide member can travel while being substantially orthogonal to each other even in a region where twisting occurs, and can be stably twisted without causing unnecessary folding. Desirable for entering.

  In addition, it is preferable to minimize the number of times the fiber bundle 1 is twisted in the manufacturing apparatus.

<Number of fiber bundle bobbins>
In the embodiment shown in FIGS. 1 and 2, only one fiber bundle bobbin 101 is shown, but the technical idea similar to that described so far, that is, the direction of action of the force acting on the fiber bundle 1 is Based on the idea that it is desirable that the fiber bundle 1 be in the thickness direction, the number of fiber bundle bobbins 101 is increased so that more fiber bundles 1 can be wound simultaneously, thereby causing unnecessary twisting and folding. Therefore, productivity can be improved.

<Process speed>
About the running speed of the fiber bundle 1, the range of 0.1-300 m / min is preferable from a viewpoint of productivity. If it is too slow, the productivity will be low, but if it is too fast, the running resistance of the fiber bundle 1 will increase, and the running amount of fiber bundle per unit time will increase. It may cause troubles such as cutting.

<Process tension>
In the production of the resin-impregnated fiber bundle wound body according to the present invention, it is preferable that the fiber bundle 1 can be prevented from loosening by winding the fiber bundle 1 while applying tension. A mechanism for applying tension may be incorporated. A preferable tension range is 0.8 to 6.7 mN / tex.

<Appropriate spacing between each part and guide>
It is preferable that the distance between adjacent guides included in each part of the unwinding unit 100, the guide unit 200, and the winding unit 300 is in the range of 20 to 500 mm. If the distance between the guides is too close, unnecessary folding easily enters the fiber bundle 1, and if the distance between the guides is too far, the apparatus not only becomes excessively large, but also unnecessary folding or twisting occurs in the fiber bundle 1. Cause.

  About the unwinding part 100, the guidance | induction part 200, and the winding part 300, although the space | interval between each adjacent part can be determined in consideration of the viewpoint of an apparatus layout, when a guide space | interval is too close as above-mentioned. If the fiber bundle 1 easily enters unnecessary folds and the guide distance is too far apart, the apparatus will not be excessively large, but will also cause unnecessary folds and twists in the fiber bundle 1, so a range of 0.3-5 m It is preferable that it exists in.

<Second Embodiment>
Next, a second embodiment according to the present invention will be described in detail with reference to FIG. Similar to the first embodiment, the second embodiment includes at least the unwinding unit 100, the winding unit 300, and the guide unit 200.

  Hereinafter, the guide part 200 including a different part from 1st Embodiment is demonstrated. In the second embodiment, the guide unit 200 is configured so that the rotation axis of the mandrel 301 and the axial direction of the mandrel 301 are aligned with each other, and the axial direction of the MH guide 202 and the fiber traveling direction. However, it is configured to include at least the MV guide 203 disposed so that the axial directions are substantially orthogonal.

<M-H guide / MV guide>
By disposing the MH guide 202, the position of the fiber bundle 1 can be changed without causing unnecessary twisting or folding, and the degree of freedom of equipment layout when the number of the fiber bundle bobbins 101 is increased. Is preferable.

  Further, the MV guide 203 is arranged on the downstream side of the MH guide 202, and is the guide that comes into contact first with the axial direction of the guide located closest to the winding portion 300 in the next step. The axial direction of the guide 305 matches. As a result, even when the amount of movement of the winding head 302 is large, the direction of the reaction force F acting on the fiber bundle 1 can be the fiber bundle thickness direction instead of the fiber bundle width direction. Desirable because no twisting occurs.

  About the number of the MH guide 202 and the MV guide 203, the optimal number for each manufacturing apparatus is selected from the viewpoint of the layout restrictions of manufacturing equipment, and the viewpoint of economical efficiency. Specifically, it is preferable to provide two or more of each because the fiber bundle 1 can be fed out stably. There is no particular limitation on the diameter of the portion of the MH guide 202 and the MV guide 203 that the fiber bundle 1 contacts, but it is preferable to use a guide in the range of 1 to 50 mm. There are no particular restrictions on the guide material and the surface treatment, and various guide members can be applied in accordance with the purpose of each manufacturing apparatus.

  Further, the guide located closest to the guide portion 200 among the F-H guides 306 and the guide located closest to the winding portion 300 among the MH guides 202 travel on both the guides and the guides. It is preferable to arrange on a plane including the fiber bundle 1.

  Further, the guide that is located closest to the unwinding portion 100 among the MH guides 202 and the guide that is the same among the CH guides 102 and the CV guides 103 that have the same axial direction as the MH guide 202. It is preferable that the guide located near the part is disposed on a plane configured to include both the guide and the fiber bundle 1 traveling on the guide.

  By applying this arrangement, the traveling direction of the fiber bundle 1 and each guide member can reliably travel substantially orthogonally even in a region where the fiber bundle 1 is twisted, without causing unnecessary folding. Desirable for stable torsion.

<Resin impregnation means>
When the fiber bundle 1 that is not pre-impregnated with the resin is used, as shown in FIG. 4, the apparatus includes the resin impregnation means 204, and the resin is impregnated with the resin. Can be sent out.

  The resin impregnation means 204 is preferably disposed on the upstream side of the MV guide 203 in the guide portion 200. More preferably, a plurality of MH guides 202 are arranged before and after passing through the resin impregnation means 204, and the axial direction of the MH guide 202 and the axial direction of the impregnation roll 205 are arranged to be aligned. Since the direction of the reaction force F can be not the fiber bundle width direction but the fiber bundle thickness direction, it is desirable that the fiber bundle 1 is not folded or twisted unnecessarily.

  The resin impregnation means 204 is not particularly limited in implementation as long as the purpose is to impregnate the fiber bundle 1 with resin, and is a dip method in which the fiber bundle is directly passed through the resin, and the fiber bundle is placed in the impregnation die. Various impregnation means such as a fixed discharge method in which the resin is drawn into and discharged into the die, and an impregnation roll method in which the fiber bundle is run and impregnated on the impregnation roll to which the resin is adhered are applicable. The impregnating roll method is suitable because the amount of resin can be adjusted accurately with respect to the simplicity of the mechanism.

  The impregnation roll method is a method in which the width of the fiber bundle is substantially proportional to the amount of resin attached, and it is essential to improve the quality to stabilize the width of the fiber bundle 1 passing over the resin impregnation roll 205. It is. As a result of preventing twisting and folding of the fiber bundle 1 by the apparatus according to the present invention, the width of the fiber bundle 1 when passing through the resin impregnated roll 205 is stabilized, so that the resin adhesion amount is stabilized and the product quality is improved. It can be improved.

  In addition, when it is set as the structure containing the resin impregnation means 204, about the guide member located downstream from the resin impregnation means 204, it is preferable to set it as the structure containing at least 1 or more fixed guide bars. When the rotating roller member is used, the fiber bundle 1 tends to stick to the surface of the rotating roller member and tends to remain wound. However, by using a fixed guide bar, such a tendency can be suppressed and the maintenance frequency is reduced. It is possible.

<Resin impregnation promoting means>
Further, as shown in FIG. 16, after passing through a resin impregnation means such as an impregnation roll 205, a resin impregnation facilitating means such as a squeezing bar 207 is included so as to wind up the resin impregnated fiber bundle. Air remaining in the body can be reduced more effectively. The type of resin impregnation promoting means is not limited to the illustrated ironing bar 207, and various impregnation promoting forms can be implemented.

  In the means by the squeezing bar 207 exemplified in the present application, the fiber bundle 1 passes through the plurality of squeezing bars 207 constrained to rotate around the axial direction of the bar while being hung in a zigzag manner. When passing through the ironing bar 207, the fiber bundle 1 receives a reaction force from the ironing bar 207 in the thickness direction. This reaction force promotes further impregnation (penetration) of the resin adhered to the fiber bundle 1 by the resin impregnation means into the fiber bundle 1 and replaces the air remaining in the fiber bundle 1 with resin. Is possible.
