発明者は、上記方法を改良して、異形管を製造し
ようとした。 Methods and apparatus for continuously manufacturing reinforced resin pipes are known. A known method involves, for example, winding an endless belt spirally at least once around a core rod fixed in a cantilevered manner, sandwiching a strip between the endless belt and the core rod, and winding the endless belt. The belt is rotated to wind the strip around the core rod to form a helical tube that progresses in a spiral, and a fiber material and a curable resin are supplied onto the spiral tube to form a tube, and this tube is the core rod. This is a method in which the resin is hardened by heating from the surroundings while it travels spirally along the rod, thereby obtaining a reinforced resin tube. In this method, the tube is formed on a helical tube, and since the helical tube must advance while rotating in a helical manner around a fixed core rod, the shape of the tube is cylindrical, i.e. , the cross section of the tube must be circular. In other words, it was not possible to manufacture irregularly shaped tubes using this method. Therefore, the inventor attempted to manufacture a deformed tube by improving the above method.

ある。 In the above-mentioned known method, the inventor maintains the outer circumferential surface of the core rod in the conventional cylindrical shape on the support side of the core rod, but makes the cross-sectional shape irregular on the tip side of the core rod,
We also attempted to rotate the cylindrical portion of the core rod together with the irregularly shaped portion in accordance with the rotation of the helical tube in the circumferential direction. In this way, after the spiral tube is formed into a cylindrical shape by the cylindrical part of the core rod, the cross section of the spiral tube is made into an irregular shape by the irregularly shaped part of the core rod, and although the spiral tube progresses in a spiral, there is no difference between the spiral tube and the core rod. There is no movement in the circumferential direction, only movement in the longitudinal direction, so that the spiral tube can maintain its irregular shape. Moreover,
The shape of the resin tube was matched to the shape of the spiral tube, and the curable resin was cured by heating from the outside while the resin tube was in an irregular shape. As a result, it was confirmed that irregularly shaped tubes could be manufactured continuously. The method of this invention was made based on such confirmation.

The cylindrical portion 2 of the core rod is integrated with the irregularly shaped portion 13, is supported in a cantilevered manner on the base 1, and is rotatable. Therefore, when the cylindrical part 2 is rotated about its central axis, the profiled part 13 is also rotated about its axis. an endless belt 4 is wound helically around the supporting side of the cylindrical part 2 at least once;
It is supported by rolls 5 and 6 and moved in the direction of arrow X. A strip 3 is sandwiched between the endless belt 4 and the cylindrical portion 2, and as the endless belt 4 moves, it is wound spirally around the core rod to form a spiral tube 7.

As mentioned above, the spiral tube 7 advances while moving in a spiral shape as a whole, but as a result of the rotation of the core rod, there is no positional deviation in the circumferential direction between it and the cylindrical portion 2, and only the longitudinal direction It will only move in the direction. The outer circumferential surface of the core rod gradually transitions from a cylindrical portion 2 to an irregularly shaped portion 13 having an oval cross section, and the transition changes as a gently curved surface. The circumferential length of the irregularly shaped portion 2 including its transition portion is substantially equal to the circumferential length of the cylindrical portion.

In this case, a tape made of release paper, for example, is used as the strip 3 and is sandwiched between the endless belt 4 and the cylindrical portion 2. The endless belt 4 is driven to continuously form the spiral tube 7 and advance in a spiral shape. In addition, the spiral tube 7
Rotate the core rod in accordance with the circumferential rotation of. In this state, a glass fiber roving 8 impregnated with a curable resin is wound around the surface of the spiral tube 7,
A reinforced resin tube is formed and this is used as an inner layer tube. A resin mortar 10 is applied on top of this. When coating, use the roll 9, and rotate the roll 9 in opposite directions with the roll 9 facing the inner layer pipe,
A resin mortar 10 is deposited to a certain thickness on the inner layer tube, thus forming an intermediate layer 11. A curable resin-impregnated glass fiber roving 12 is further wound around the intermediate layer 11 to form an outer layer tube. These layers are formed within the range where the cylindrical portion 2 exists, and are brought into close contact with each other to form a resin tube containing fibers therein.

3 carried above. The resin pipe carried onto the irregularly shaped part 13 changes in close contact with the curved surface on the irregularly shaped part 13,
The cross section gradually changes from cylindrical to oval. The resin tube itself moves in a spiral motion, but since the core rod is rotated in accordance with the rotation of the spiral tube 7, between it and the irregularly shaped portion 13, it only moves in the axial direction. It is. In this way, the oval shaped resin tube 14 maintains its oval shape. The egg-shaped resin tube enters the heating tool 15 as it is, and is heated there to speed up the curing of the resin, thereby creating a reinforced resin deformed tube. Thereafter, if a release paper is used as the strip 3, the release paper is removed from the irregularly shaped tube.

In order to improve the sliding between the cylindrical part 2 and the
It is also desirable to insert steel balls onto the surface of the irregularly shaped portion 13. That is, as shown in FIG. 2, a steel ball 16 is attached so that the tip of the steel ball 16 slightly protrudes from the above-mentioned surface, and the spiral tube 7 contacts this steel ball while rotating the steel ball. , preferably moving over the surface. Also, the third
As shown in the figure, the cylindrical part 2 and the irregularly shaped part 13
A spiral groove 17 is provided on the surface of the core rod, and a large number of small holes 18 are bored at the bottom of the groove, and the air inside the core rod is blown out from the small holes 18 to prevent the spiral tube 7 from rising from the surface of the core rod. It can also improve slippage.

In an apparatus for manufacturing a reinforced resin tube that supplies fiber material and hardening resin around a spiral tube 7, the outer peripheral surface of the core rod is made cylindrical on the support side, and the cross section on the tip side is made into a cylindrical shape. The circumference of the irregularly shaped part 13 is made substantially equal to the circumference of the cylindrical part 2, and the cylindrical part 2 is rotated together with the irregularly shaped part 13 in accordance with the rotation of the helical tube 7 in the circumferential direction. This is a continuous manufacturing device for reinforced resin deformed tubes, which is equipped with a heating tool on the tip side.

の価値が大きい。 According to the method and device of this invention, the cylindrical portion and the irregularly shaped portion of the core rod are rotated together in accordance with the rotation of the helical tube in the circumferential direction.
The helical tube can easily transition from the cylindrical portion to the irregularly shaped portion, and the spiral tube on the irregularly shaped portion can maintain the shape of the irregularly shaped portion while proceeding in a spiral manner. Therefore, according to this method and apparatus, a deformed tube made of resin containing a fiber material can be easily and continuously manufactured on a spiral tube. In addition, in the irregularly shaped tube thus obtained, the fiber material is a continuous elongated material, which is oriented spirally within the irregularly shaped tube, so that the obtained irregularly shaped tube has high strength. Further, the irregularly shaped tube is not limited to a single layer, but may also be made of multiple layers. Therefore, by appropriately combining the materials of each layer, composite pipes with various characteristics can be manufactured. In addition, by replacing the irregularly shaped portion 13 and changing its cross-sectional shape, the cross-section becomes oval,
Oval and polygonal cylinders can be easily manufactured. Therefore, the method and device of this invention have great practical value.
