TECHNICAL FIELD OF THE INVENTION
The present invention relates to a spinning sleeve used for winding when spinning glass fiber.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a paper sleeve (tube) has been used as a winding portion when spinning glass fiber (a paper sleeve cannot be found in patent literature).
[0003]
This sleeve has the advantages that it can be used at a certain high temperature and that it is inexpensive.
[0004]
However, this sleeve has a short life and has a problem in durability, and may be damaged during operation.
[0005]
[Problems to be solved by the invention]
Accordingly, an object of the present invention is to provide a spinning sleeve which has a low running cost and is more durable than the conventional one.
[0006]
[Means for Solving the Problems]
In order to solve the above problems, the present invention employs the following technical means.
[0007]
{Circle over (1)} The spinning sleeve of the present invention is characterized in that a core wire and / or a rubber layer are arranged between canvases and integrally formed into a cylindrical shape.
Since this spinning sleeve is integrally formed into a cylindrical shape with a core wire and / or a rubber layer disposed between canvases (either one of the core wire and the rubber layer may be used), it is generally used in general. It can be manufactured without a special manufacturing process in a manufacturing process similar to a friction transmission belt such as a V-ribbed belt. Further, the durability is improved as compared with the paper-made one.
[0008]
In addition, nylon 6 (trademark), nylon 66 (trademark), cotton, PET, aramid, or the like can be used as the canvas.
[0009]
{Circle around (2)} The core wire may be arranged between the dipped canvases so as to be integrally formed into a tubular shape.
[0010]
That is, it has a structure of canvas (dip cloth) / core wire / canvas (dip cloth). Here, the dipping process refers to a process of impregnating a rubber paste, an RFL solution, a resin, and the like. With this configuration, it is possible to further improve productivity and durability. If the rubber layer is omitted, the weight can be reduced.
[0011]
{Circle around (3)} A rubber layer may be arranged between the dipped canvases to be integrally formed into a cylindrical shape.
[0012]
That is, it has a structure of canvas (dip cloth) / rubber layer / canvas (dip cloth). With such a configuration, productivity is good, and the canvas and the rubber layer on the both sides provide strength as a whole against internal pressure and external pressure applied during spinning operation of glass fiber or the like, thereby providing cushioning. Also, omitting the cord facilitates removal of the glass fiber during the spinning operation.
[0013]
{Circle around (4)} The canvas may be coated with rubber glue or bonded to rubber.
[0014]
That is, it has a structure of canvas (cloth treated by dip treatment and bonded with rubber glue coating or rubber) / core wire or / and rubber layer / cloth (cloth treated by dip treatment and bonded with rubber glue coating or rubber). I have. With this configuration, the waterproofness and the adhesion between the canvas and the core wire and / or the rubber layer are improved.
[0015]
{Circle around (5)} The spinning sleeve can be used by being mounted on the outer periphery of a rotary drum of a winding machine. If a known arm mechanism is built in the drum, when the drum is driven, the arm mechanism expands by centrifugal force and is pressed against the inner peripheral surface of the spinning sleeve. At the time of spinning, the spun fibers are wound around a sleeve that rotates on a drum. During spinning, the arm mechanism is brought into close contact with the inner peripheral surface of the sleeve by centrifugal force, and the rotational movement of the drum is transmitted accurately.
[0016]
However, at the start of winding (at the start of spinning), the sleeve is light, so it follows the rotation of the drum smoothly. However, when the spinning speed of the drum is reduced at the end of the spinning operation, the centrifugal force decreases and the arm mechanism , The adhesiveness to the inner peripheral surface of the spinning sleeve decreases, slips occur between them, causing a slip phenomenon (idling), and skidding out of the arm mechanism. There can be. At the end of the winding, the entire sleeve is heavier due to the weight of the wound fiber, which is affected by the inertia of trying to continue the movement. Therefore, it is preferable to use a spinning sleeve that does not easily jump out of the arm mechanism even when the rotation speed decreases.
[0017]
Therefore, this spinning sleeve is used by being mounted on a rotary drum having a built-in arm mechanism that expands by centrifugal force, and the convex pattern on the inner peripheral surface of the canvas rotates when it comes into contact with the arm mechanism at the end of rotation. It may be formed so that a component force displaced to the back side of the drum is generated.
[0018]
That is, when the sleeve and the arm mechanism are separated from each other at the end of rotation (they come into contact with or separate from each other because they are floating. Usually, the inner lower surface of the sleeve separates from the arm mechanism due to the weight of the sleeve). The convex pattern (for example, cloth) on the inner peripheral surface causes the sleeve to move to the back side of the rotary drum (the flange side opposite to the front side for attaching and detaching the sleeve to and from the drum). To the side where the sleeve is attached and detached).
[0019]
With this configuration, when the rotation speed of the drum is reduced at the end of the spinning operation, even if the arm mechanism is contracted due to a decrease in the centrifugal force and a slip occurs with the sleeve, When a convex pattern formed on the inner circumferential surface of the canvas and the arm mechanism come and go while slipping, a component force that is displaced to the far side of the rotating drum is generated, so that it is displaced in the direction of protruding from the drum (operator side). hard.
[0020]
That is, in actual work, the sleeve does not move to the near side (operator side) when the sleeve is attached and the winding is started, and when the winding is stopped, the movement of the sleeve to the near side is determined on the inner circumferential surface of the canvas. This is intended to be prevented by thrust generated by a convex pattern (for example, cloth texture).
[0021]
{Circle around (6)} The convex pattern on the inner peripheral surface of the canvas may be formed by a woven pattern in which warp yarns and weft yarns follow diagonally and textures appear diagonally.
[0022]
The raw fabric of the canvas is formed by entanglement of the warp and the weft with each other. However, when configured as described above, the texture of the warp and the weft appears diagonally following the diagonal (the convex pattern on the inner peripheral surface of the canvas). By contact with the arm mechanism, "component force in the direction of rotation (peripheral direction of the sleeve)" and "component force in the direction perpendicular to the direction of rotation (peripheral direction of the sleeve)", that is, in the axial direction of the rotary drum A component force that is displaced toward the back or front side is generated.
[0023]
Then, the texture of the convex pattern on the inner circumferential surface of the canvas (the texture in which the warp and weft yarns are obliquely successively appearing obliquely) is changed to the texture on the Z surface with respect to the rotation direction of the drum (the circumferential direction of the sleeve). The selection may be made so as to generate a component force displaced to the back side of the drum by selecting either the texture or the texture of the S surface. For example, the texture may be appropriately set in accordance with the relationship with the rotation direction of the drum and the relationship with the direction in which the sleeve is attached or detached (for example, right or left as viewed from the operator with respect to the axial direction of the drum). Just fine.
[0024]
{Circle around (7)} The cord may be a glass cord, a PET cord or an aramid cord. These cords are preferable in terms of preventing breakage and improving durability.
[0025]
(8) The rubber layer may be made of EPDM rubber, chloroprene rubber, hydrogenated nitrile butadiene rubber, urethane rubber, nitrile butadiene rubber (NBR), styrene butadiene rubber (SBR), or chlorosulfonated polyethylene (CSM). .
[0026]
If EPDM rubber is used for the rubber layer, the price can be reduced as a whole and the heat resistance can be improved.
[0027]

Further, a coating layer made of rubber glue is formed between the core wire 4 (the basic structure thereof is the same as that of the first embodiment).
[0060]
The spinning sleeve 1 is used by being mounted on the outer periphery of a rotary drum 7 (see FIG. 11) of a winding machine (not shown). A known arm mechanism 8 is built in the drum 7. When the drum 7 is driven, the arm mechanism 8 is expanded by centrifugal force and pressed against the inner peripheral surface of the spinning sleeve 1. At the time of spinning, the spun fiber 2 (see FIG. 1) is wound around a sleeve 1 rotating on a drum 7. During spinning, the arm mechanism 8 is brought into close contact with the inner peripheral surface of the sleeve 1 by centrifugal force, and the rotational movement of the drum 7 is transmitted accurately.
[0061]
That is, the spinning sleeve 1 is used by being mounted on a rotary drum 7 having an arm mechanism 8 that expands by centrifugal force.

The original fabric of the canvas 3 is formed by entanglement of the warp yarns 11 and the weft yarns 12 with each other, and the texture of the warp yarns 11 and the weft yarns 12 appears obliquely and subsequently obliquely (the convex pattern 9 on the inner peripheral surface of the canvas 3). The contact between the arm mechanism 8 and the convex portion on the outer peripheral surface causes the "component force in the rotational direction (the circumferential direction of the sleeve 1)" and the "component force in the direction perpendicular to the rotational direction (the circumferential direction of the sleeve 1)". That is, a component force that is displaced in the axial direction of the rotary drum 7 (rear side or front side) is generated.
[0066]
Here, the texture of the convex pattern 9 on the inner peripheral surface of the canvas 3 (the texture in which the warp of the warp yarn 11 and the weft yarn 12 appear obliquely and obliquely) is applied in the rotation direction of the drum 7 (the circumferential direction of the sleeve 1). On the other hand, by selecting either the cloth on the Z plane or the cloth on the S plane, it is set so that a component force (F) displaced toward the back side (the flange 10 side) of the drum 7 is generated. The texture is appropriately set according to the relationship with the rotation direction of the drum 7 and the relationship with the direction in which the sleeve 1 is attached and detached (for example, right or left as viewed from the operator with respect to the axial direction of the drum 7). However, in this embodiment, the Z surface is used. That is, the entire sleeve 1 is set so as to be displaced toward the flange 10 on the back side of the drum 7 by the convex pattern 9 of the canvas 3 on the inner peripheral surface in relation to the rotation direction.
[0067]
In the spinning sleeve 1, when the rotation speed of the drum 7 is reduced at the end of the spinning operation, the arm mechanism 8 is closed and closed due to a decrease in the centrifugal force, and a slip occurs with the sleeve 1. When the arm mechanism 8 comes into contact with the convex pattern 9 formed on the inner peripheral surface of the canvas 3 while slipping, a component force (F) displaced to the rear side of the rotating drum 7 is generated. There is an advantage that it is difficult to be displaced in the direction of protruding from the (worker side).
[0068]
