Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, when unwinding a strand from the inner layer of a wound body of glass fiber, ceramic fiber, carbon fiber, metal fiber, etc., collapses the outer layer of the wound body. The present invention relates to a fiber wound body holding member used for preventing.

[0002]

2. Description of the Related Art Conventionally, as a glass fiber wound body wound in a cylindrical shape, for example, a glass fiber strand cake which is unwound in order from the inner layer and is used for manufacturing chopped strands, cloths, mats, etc. Hereinafter, it is known that a glass fiber roving (hereinafter, simply referred to as roving) used for producing chopped strands, spray-up method, filament winding method, or the like will be simply referred to as cake). The latter rovings are roughly classified into so-called direct winding rovings and combined yarn rovings due to the difference in the manufacturing method.

In the above-mentioned cake and direct winding roving, a binder as a sizing agent is applied to a strand which is a bundle of glass fibers called hundreds to thousands of filaments spun from a bushing made of platinum. After that, these are bundled by a member called a shoe and wound into a cylindrical shape by a winding machine having a mechanism that is traversed in the axial direction. On the other hand, the compound yarn roving is a cylindrical shape with a traverse eye that reciprocates parallel to the axis of the winder by pulling out each strand from the cake set in the creel, bundling while applying tension, and passing through the guide. It is manufactured by winding it up. In both of these manufacturing processes, in each case, tension is applied to the strands, so that the glass fiber winding body is wound in a tightly tightened state.

The glass fiber roll produced in this manner is used as it is in an unwrapped state in the subsequent processing step, or is used as a glass fiber roll during transportation and handling. The product is wrapped in a heat-shrinkable film and shipped so as not to be scratched. When the glass fiber wound body is used in the subsequent processing step, it is usually unwound by sequentially pulling out the strands from the inner layer portion of the glass fiber wound body.
In this case, although the glass fiber winding body is wound in a tightly wound state as described above, the position where the strand is pulled out from the glass fiber winding body reaches the vicinity of the outer layer portion, and the glass fiber When the winding thickness of the remaining portion of the wound body becomes thin, even if a slight external force pulling the wound glass fiber body is applied, the remaining portion of the wound glass fiber body collapses inward due to its own weight. .

In this case, if the collapsed degree of the glass fiber winding body is small, the strand becomes looped and the pulling operation is hindered. On the other hand, if the collapsed degree is large, the strand becomes complicated. It causes entanglement and collapse. When such a situation occurs, the strand is clogged in the guide of the supply device, and the strand cannot be continuously drawn out. As a result of this, the production process is disturbed and the waste of strands increases.

In order to deal with such a problem, for example, according to Japanese Patent Publication No. 7-10708, a heat-adhesive sheet material (or a heat-adhesive film) is adhered to the outer circumferential surface of the roving, and the entire outer circumference is described above. A technique for preventing the collapse of roving by wrapping with a heat-shrinkable film that adheres to a heat-adhesive sheet material is disclosed. In addition, JP-A-4-8
According to Japanese Patent No. 7972, a non-shrink film partially entering between strands of the outermost layer of roving is joined to its outer peripheral surface, and the entire outer circumference is wrapped with a heat shrink film that adheres to the non-shrink film. Discloses a technique for preventing collapse of roving.

[0007]

By the way, in the prior art, in order to prevent collapse of any glass fiber wound body including the techniques disclosed in the above-mentioned publications at the time of drawing out a strand in a processing step, Since it is necessary to once package the heat-shrinkable film or the like, the following problems occur.

That is, an expensive device or equipment for packaging the package is required, which leads to an increase in running cost, and the package is individually packaged for each glass fiber winding body. The used package package of the glass fiber roll has to be discarded, which is not only wasteful but also causes a large amount of waste.

Immediately after the production of the glass fiber winding body by winding, if the fiber winding body is immediately used in the processing step, a heat shrinkable film, a non-shrinkable film, a heat-adhesive sheet or the like. There is a problem that not only the time and labor required for preparation and packaging of the product become great, but also wasteful work time is required.

Therefore, in such a case, since it is the actual situation that the strand is pulled out from the inner layer portion of the glass fiber winding body without taking measures to prevent the collapse of the glass fiber winding body, There is a problem that a large loss occurs in the work because the work of pulling out the strand must be executed while coping with various troubles caused by the collapse of the fiber winding body on the spot.

The above problems can occur not only in the glass fiber winding body but also in the ceramic fiber winding body, the carbon fiber winding body, the metal fiber winding body and the like. .

The present invention has been made in view of the above circumstances, and is easy to wind and mount on the outer peripheral surface of a fiber winding body,
It is also an object of the present invention to provide a fiber winding body holding member that can be repeatedly used many times and that can appropriately pull out strands while appropriately preventing collapse of the fiber winding body outer layer portion. Subject.

[0013]

DISCLOSURE OF THE INVENTION The present invention, which has been made in order to achieve the above-mentioned technical object, provides a method of winding a fiber in the case of unwinding a strand from an inner layer portion of a fiber winding body which is wound in a cylindrical shape. In a fiber winding body holding member arranged on the outer peripheral side of the body to prevent the outer layer portion from collapsing, a sheet fastener is attached to the surface of a sheet member with its fastening surface exposed on the front side. In addition, the sheet member can be bent and deformed into a cylindrical shape so that the fastening surface of the planar fastener can be joined to the outer peripheral surface of the fiber winding body, and one end portion in the circumferential direction of the sheet member is formed. It is characterized in that the vicinity and the vicinity of the other end can be attached and detached.

Here, the term "planar fastener" means a planar fastener on only one side of a pair of removable planar fasteners. Further, in this case, the "planar fastener" includes a hooking side that is a male side, for example, a side on which an engaging surface including a hook-shaped or mushroom-shaped engaging portion is present, and a hooked side that is a female side, for example, a loop. When there is a distinction from the side on which the engaging surface composed of a ring-shaped engaging portion is present, a male surface fastener is preferable, and in any case, the outer peripheral surface (strand) of the fiber winding body Any type of sheet fastener may be used as long as it has a fastening surface that is hooked on. Specifically, the male side of Velcro "Velcro" A03800 (manufactured by Kuraray Co., Ltd.) is preferably used as the planar fastener.

According to this structure, the sheet member is bent into a cylindrical shape and wound around the outer periphery of the fiber winding body, so that the engaging surface of the sheet-shaped fastener attached to the sheet member is wound around the fiber winding body. It is joined to the outer peripheral surface of the body, and while maintaining this state, the vicinity of one end and the vicinity of the other end of the sheet member are fixed by the attaching / detaching means. As a result, the outer circumference of the fiber winding body is covered with the sheet member, and the fastening surface of the planar fastener is hooked on the outer circumferential surface of the fiber winding body, so that the outer layer portion of the fiber winding body is appropriately formed. The sheet member is held with a sufficient holding force. More specifically, a large number of engaging portions that form the fastening surface of the sheet fastener enter the filaments that form the strands of the outer layer of the fiber winding body, so that the outer layer portion of the fiber winding body has a planar shape. It is entangled with the fastening surface of the fastener, whereby the outer layer of the fiber winding body is held by the sheet member. In such a state, by pulling out the strands from the inner layer of the fiber winding body and unwinding the strands in sequence, the pulling position reaches the outer layer portion of the fiber winding body, and the winding thickness of the remaining portion of the fiber winding body. Even when the fiber winding becomes thin, the outer layer part of the fiber winding body is held by being caught by the planar fastener, so that the formation of loops of the strand and the collapse of the strand are prevented, and the position where the strand is pulled out is The pulling out work is performed smoothly up to the vicinity of the outermost layer of the revolving body.

Therefore, the waste of the strand is extremely small, and the waste is not generated, and the conventional apparatus and equipment for package packaging are not required, and the running cost can be reduced. Moreover, since the sheet member can be immediately wrapped around the outer periphery of the fiber wound body immediately after the production of the fiber wound body, various preparations such as package packaging and complicated labor and labor are required. It becomes unnecessary, and the pulling out of the strand can be started in a short time without causing a loss. After the drawing operation is completed, the sheet member is returned to the original state by separating the vicinity of one end and the other end of the sheet member, and the sheet member is wound around the subsequent fiber winding body again in the same manner. Since it is possible to perform the work of pulling out the strand,
It is possible to repeatedly use the same fiber winding body holding member many times.

In this case, it is preferable that the sheet member can be bent into a cylindrical shape by elastic deformation. By doing so, the flat sheet member can be bent and deformed into a cylindrical shape when in use, and can be flattened again by the restoring force due to elasticity when not in use. The members can be stacked and stored, and the fiber winding body holding member can be made compact and the storage space can be narrowed during storage.

The sheet member is preferably made of resin. That is, as the characteristics of the sheet member, it is necessary that the sheet member can be easily bent and deformed into a cylindrical shape along the outer peripheral surface of the fiber winding body, and that it has appropriate rigidity and elasticity. , It is preferable to use a resin as the material satisfying these characteristics,

Specifically, it is preferable that the sheet member is polypropylene resin and the thickness thereof is 0.3 to 1.4 mm. That is, when a polypropylene resin is used as the material of the sheet member among the resins, if the thickness is less than 0.3 mm, the rigidity is insufficient, so that the fiber wound body is pulled out from the inner layer portion of the strand. As the winding thickness of the remaining portion becomes smaller, the sheet member collapses together with the fiber winding body. On the other hand, if the thickness exceeds 1.4 mm, the rigidity becomes excessively high. Therefore, in the state where the sheet member is bent and deformed into a cylindrical shape, the vicinity of one end portion and the vicinity of the other end portion thereof can be simplified. It cannot be easily attached and detached, and moreover, a great deal of labor is required for bending and deforming work, resulting in deterioration of workability. Therefore, in order to prevent these problems, the thickness should be set within the above range.

Further, the dimension of the sheet member in the width direction orthogonal to the circumferential direction is 70 in the axial direction of the fiber winding body.
% Or more, and it is preferable that the sheet fastener is attached in a region extending from the vicinity of one end to the vicinity of the other end in the width direction of the sheet member along the circumferential direction of the sheet member. That is, when the widthwise dimension of the sheet member is less than 70% of the axial direction of the fiber winding body, the area of the outer peripheral surface of the fiber winding body in which the engaging surface of the planar fastener is caught and entangled is also narrower than 70%. Since the area becomes a region and the area in which the two are entangled with each other becomes excessively small, the wound fiber body may be collapsed. Therefore, by setting this to 70% or more, and more preferably 80% or more, the collapse of the fiber winding body can be appropriately prevented. In this case, 70% or 80% of the area is preferably an area obtained by evenly distributing to both sides with the axial center of the fiber winding body as a reference.

Further, with respect to the above-mentioned area of the sheet member,
One sheet-shaped fastener having a width over the entire area may be attached to the sheet member, but a plurality of sheet-shaped fasteners may be attached at predetermined intervals in the width direction of the sheet member. May be. According to the method of adhering a plurality of planar fasteners in this manner, the planar fasteners can be appropriately arranged only in a necessary area by using a thin planar fastener that is less than 1/2 of the area width described above. It is possible to efficiently prevent collapse of the fiber winding body while reducing the material cost of the fastener.

The planar fastener is extended to the vicinity of one end portion in the circumferential direction of the sheet member, and a fastening fastener is attached to the back surface of the sheet member near the other end portion in the circumferential direction. It is preferable that the attachment surface is attached so that the attachment surface is exposed on the back surface side. In this case, when the sheet fastener attached to the surface of the fiber winding body is the male side,
The fastening surface fastener is on the female side, but the opposite may be done as long as the operations of both are properly performed. When the male side of the above-mentioned Velcro “Velcro” A03800 (manufactured by Kuraray Co., Ltd.) is used as the surface fastener on the front surface side of the sheet member, the fastening fastener is used as the fastening surface fastener. Is preferably used. According to this structure, by attaching and detaching the sheet fastener and the fastening sheet fastener that are entangled with the outer peripheral surface of the fiber winding body, under the state where the sheet member is bent and deformed into a cylindrical shape, one end portion thereof is formed. The vicinity and the vicinity of the other end are fixed and separated. Therefore, the planar fastener on the surface of the sheet member serves both to prevent the collapse of the fiber winding body and to attach / detach the fastening portions near both ends of the sheet member, thus reducing the number of components or parts. At the same time, the attachment / detachment work at the fastening portion is greatly facilitated, and it is possible to perform the winding attachment / detachment with one touch.

In the above invention, when the fiber winding body is arranged so that the axis of the fiber winding body is along the horizontal direction, the unwinding is performed by pulling out the strand from the inner layer portion thereof. Especially effective. Further, the above invention is applied to any fiber winding body such as the above-mentioned cake, direct winding roving, and compound yarn roving.

It suffices that it has the rigidity to obtain, and also has the elasticity capable of returning to the flat plate shape when the fastening between the first fastener 3 and the second fastener 4 is released. In addition, this sheet member 2
The length L of the first fastener 3 and the second fastener 4 is longer than the circumferential dimension of the outer peripheral surface of the fiber winding body R by the length necessary for the first fastener 3 and the second fastener 4 to be fixed to each other by overlapping. There is.

One of the first fasteners 3 is attached to the surface of the sheet member 2 in the vicinity of one end in the width direction along the circumferential direction, and the other is in the vicinity of the other end of the surface of the sheet member 2 in the width direction. It is adhered along the circumferential direction, and there is a predetermined gap between them. These two first fasteners 3

Fiber-wound body holding member 1 having the above structure
Is used in the following manner. That is, in a general production line, after a fiber winding body is manufactured by a fiber winding body winding machine, the fiber winding body is hung on a hanger conveyor or the like, or is placed on an ordinary conveyor or a carriage to be conveyed. However, in the present embodiment, the above-described fiber wound body holding member 1 is wound around and attached to the fiber wound body R that is moving while being hung on the hanger. Then, the fiber winding body R on which the fiber winding body holding member 1 is wound and mounted is replaced on the creel stand, and the strand Rs is unwound from the inner layer portion of the fiber winding body R in the creel stand. The strand Rs thus drawn out is cut by a cutting device.

In this case, the winding and mounting of the fiber winding body holding member 1 is performed by first bending the sheet member 2 so that the first fastener 3 is along the outer peripheral surface of the fiber winding body R as shown in FIG. In the state where the sheet member 2 is bent and deformed into a cylindrical shape so that the first fastener 3 is bonded to the entire outer peripheral surface of the fiber wound body R, the arrangement position of the second fastener 4 in the sheet member 2 is changed. The vicinity of the other end is overlapped on the outer peripheral side, and the end of the first fastener 3 and the second fastener 4 are fixed to each other. As a result, the sheet member 2 has a cylindrical shape and is wound around the outer peripheral side of the fiber winding body R, and at the same time, the male side engaging member forming the engaging surface of the first fastener 3 is engaged. The parts enter between the filaments of the strands in the outer layer part of the fiber winding body R, and the outer layer part is held by the sheet member 2 with a light engagement force.

After this, the strands Rs are drawn out from the inner layer portion of the fiber winding body R. At this time, the fiber winding body R has its axis as shown in FIGS. 3 (a) and 3 (b). The heart is set horizontally. In such a state, even when the winding thickness of the remaining portion of the fiber winding body R is reduced by pulling out the strands Rs from the inner layer portion of the fiber winding body R and sequentially unwinding them. Fiber winding body R
The outer layer portion of is held by being caught by the first fastener 3. Therefore, it is possible to prevent problems such as the strands becoming looped or falling, and the drawing work is smoothly performed until the drawing position of the strand reaches the vicinity of the outermost layer portion of the fiber winding body R.

When the fiber wound body holding member 1 is not used, the first fastener 3 and the second fastener 4 are separated from each other, and the sheet member 2 is flattened by the restoring force of the elasticity of the sheet member 2. . By stacking and storing a large number of plate-shaped fiber wound body holding members 1 in this way, the aggregate of the fiber wound body holding members 1 at the time of storage can be made compact and the storage space can be narrowed. it can. After that, upon request, the same sheet member 2 is wound around another fiber winding body R again to form the strand Rs.
Since the drawing operation can be performed, the same fiber wound body holding member 1 can be repeatedly used many times.

FIGS. 4 (a) and 4 (b) illustrate a fiber wound body holding member 1 according to a second embodiment of the present invention,
The difference from the above-described first embodiment is that a single first fastener 3 having a large width is attached over substantially the entire surface of the sheet member 2. Therefore, according to this 2nd Embodiment, there exists an advantage that the engaging force with the outer peripheral surface of the fiber winding body R becomes as large as possible. Since other configurations are the same as those of the above-described first embodiment, the same function and effect can be obtained for the same portions.

FIGS. 5 (a) and 5 (b) illustrate a fiber wound body holding member 1 according to a third embodiment of the present invention,
The difference from the first embodiment described above is that three first fasteners 3 are attached to the surface of the sheet member 2 at predetermined intervals. Therefore, according to the third embodiment, the thin first fastener 3 can be appropriately arranged only in a necessary region, so that the material cost of the first fastener 3 can be reduced while the collapse of the fiber winding body R can be efficiently performed. The advantage is that it can be well prevented. Since other configurations are the same as those of the above-described first embodiment, the same function and effect can be obtained for the same portions.

The fiber winding body holding member according to the above embodiment is not limited to the glass fiber winding body, but may be the ceramic fiber winding body, the carbon fiber winding body, or the metal fiber winding body. The same can be applied. Further, the fiber winding body R used in the above embodiments may be any of so-called cake, direct winding roving and compound yarn roving.

Is. Further, Examples 1, 2, and 3 adopted the configuration of the sheet member shown in FIG. 1, and Example 4 adopted the configuration of the sheet member shown in FIG.

[0036]

[Table 1]

With reference to Table 1 above, as Example 1 of the present invention, glass in which the thickness of the polypropylene sheet member is 0.25 mm and the width of each of the two first fasteners is 100 mm A test was carried out in which a fiber winding body holding member was manufactured, and this was wound around and mounted on the outer periphery of 100 rovings, and strands were pulled out from the inner layer portion and unwound sequentially. As a result, when the unrolling progresses to the vicinity of the outer layer portion of the roving, the sheet member tends to be crushed as the roving gradually becomes crushable, and the roving 1 of the strand that cannot be unrolled 1
The weight per piece was 130 g, and the collapse prevention effect was relatively small.

As Example 2 of the present invention, a glass fiber wound body holding member having a polypropylene sheet member having a thickness of 0.75 mm and two first fasteners each having a width of 50 mm was manufactured. The same test as in the case of 1 was performed.
As a result, roving of the strand that could not be unwound 1
The weight per piece was 65 g, and it was possible to obtain a certain degree of collapse prevention effect. In the case of this test, 10
Among the 0 pieces, there were a mixture of one that could be unwound without the collapse of roving and one that could collapse.

As Example 3 of the present invention, a glass fiber wound body holding member having a polypropylene sheet member having a thickness of 0.75 mm and two first fasteners each having a width of 100 mm was manufactured. The same test as in the case of 1 was performed. As a result, most of the rovings could be unwound smoothly to the outermost layer, and a sufficient fall prevention effect could be obtained. Specifically, the weight of each unroving strand per roving was 25 g, and the generation of waste was greatly reduced compared to the conventional example.

As Example 4 of the present invention, a polypropylene fiber sheet member having a thickness of 0.75 mm and a single first fastener adhered over substantially the entire area of the sheet member to hold a glass fiber wound body. A member was manufactured and the same test as in Example 1 was performed. As a result, most of the rovings could be unwound smoothly to the outermost layer, and a sufficient fall prevention effect could be obtained. Specifically, the weight per roving of the strand that could not be unwound was 2 as in the case of Example 3.
The amount of waste was 5 g, and the generation of waste was greatly reduced compared to the conventional example.

As a comparative example, a test was conducted in which the strands were pulled out from the inner layer portion of 100 rovings and unwound in sequence without winding the glass fiber wound body holding member.
As a result, very few unwindable strands could be unwound to the outermost layer, unstretchable strands weighed 140 g per roving, and a large amount of waste was generated.

[0042]

As described above, according to the fiber wound body holding member of the present invention, the sheet fastener is attached to the surface of the sheet member, and the sheet member can be bent and deformed into a cylindrical shape. Moreover, since the vicinity of one end and the vicinity of the other end of the sheet member in the circumferential direction can be attached and detached, the sheet member is bent into a cylindrical shape and wound around the outer periphery of the fiber winding body, and the vicinity of one end of the sheet member is provided. By fixing to the vicinity of the other end, a large number of engaging portions of the planar fastener adhered to the sheet member enter between the filaments forming the strands of the fiber winding outer layer portion, The outer layer of the fiber winding body is intertwined with the sheet fastener. As a result, even when the winding thickness of the remaining portion of the fiber winding body is thinned by pulling out the strands from the layer portion of the fiber winding body and unwinding the strands in sequence, the outer layer of the fiber winding body is reduced. Since the portion is held by being caught by the planar fastener, the work of smoothly pulling out the strand is performed up to the vicinity of the outermost layer portion of the fiber winding body. As a result, the waste of the strand becomes extremely small, waste is not generated, and the conventional apparatus and equipment for package packaging are not required, and the running cost can be reduced. Moreover, the same fiber wound body holding member can be repeatedly used many times, and the manufacturing cost of the fiber wound body holding member can be reduced.

If the sheet member can be bent into a cylindrical shape by elastic deformation, the flat sheet member can be bent and deformed into a cylindrical shape when in use, and can be made into a flat plate shape by an elastic restoring force when not in use. Therefore, when not in use, it is possible to stack and store a large number of flat plate-shaped fiber wound body holding members, which makes it possible to make the fiber wound body holding members compact and to reduce the storage space during storage. Becomes

If the sheet member is made of resin, it can be easily bent and deformed into a cylindrical shape along the outer peripheral surface of the fiber winding body, and has appropriate rigidity and elasticity. This is advantageous in obtaining advantageous properties such as the above.

Further, if the sheet member is made of polypropylene resin and has a thickness of 0.3 to 1.4 mm,
A situation in which the sheet member collapses together with the fiber winding body due to insufficient rigidity and a situation in which bending deformation work is hindered due to excessive rigidity are appropriately avoided.

The widthwise dimension of the sheet member, which is orthogonal to the circumferential direction, is 70 times the axial dimension of the fiber winding body.
% Or more, and when the planar fastener is attached along the circumferential direction of the sheet member in a region from the vicinity of the one end to the vicinity of the other end in the width direction of the sheet member, the planar fastener and the fiber can be obtained. You can secure a sufficient area to entangle with the winding body,
The collapse of the fiber winding body can be appropriately prevented.

By attaching a plurality of sheet fasteners at predetermined intervals in the width direction of the sheet member, the sheet fasteners can be appropriately arranged only in the necessary area, and the material cost of the sheet fastener can be reduced. It is possible to efficiently prevent collapse of the wound fiber body.

In addition, the sheet fastener is extended to the vicinity of one end portion in the circumferential direction of the sheet member, and is attachable to and detachable from the sheet fastener on the back surface near the other end portion of the sheet member in the circumferential direction. If a fastening surface fastener is attached, the surface fastener on the surface of the sheet member serves both for preventing collapse of the fiber winding body and for fastening near both ends of the sheet member. Alternatively, the number of parts can be reduced, and the winding mounting and removal can be performed with one touch.
