The rotation shaft 110 may be directly coupled to the drive source 111 and rotated, and may be indirectly rotated by a rotational force transmission means such as a belt or a chain. The rotation shaft 110 has a circular cross section and a long shaft shape in the longitudinal axis direction.

Referring to FIG. 1, the mold 120 is disposed to cover a circumference of the rotation shaft 110 and is rotatable with the rotation shaft 110 to move relative to the longitudinal direction of the rotation shaft 110. The pipe forming material 10 provided on the outer surface of 120 is wound on this outer surface and advanced. The speed at which the mold 120 moves in the longitudinal direction of the rotation shaft 110 is a factor for determining the production speed of the pipe. The pipe forming material 10 includes various long fibers such as glass fibers, carbon fibers or aramid fibers, and fillers such as mortar. However, the present invention is not limited thereto.

The mold 120 may be a steel band type and a collect type. Since the steel band type is described in Korean Patent No. 10-0853823 by the present applicant, detailed description thereof will be omitted.

Hereinafter, a case in which the mold 120 is a collect type will be described in detail with reference to FIGS. 2 to 7. At this time, referring to Figure 2, in this case, the manufacturing apparatus 100, in addition to the rotary shaft 110 and the mold 120, the rotating means 130 and the moving means 140 for driving the mold 120. It includes. 2 to 6, the configuration of the structure 230 is omitted in order to make it easier to understand the configuration of the mold 120 of the collect type.

The molds 120 are disposed along the circumferential direction of the rotation shaft 110 to surround the circumference of the rotation shaft 110. The molds 120 are arranged side by side with respect to the longitudinal axis direction (X-X direction), and are formed long in the longitudinal axis direction (X-X direction). In addition, the mold 120 has the same length and the same width. The molds 120 are arranged in close contact with each other to the extent that relative forward and backward movement between the molds 120 adjacent to the longitudinal axis direction (X-X direction) is possible. Therefore, the outer surfaces of the mold 120 has a cylindrical structure as a whole, but is not necessarily limited thereto. The outer surfaces of the mold 120 may have a polygonal pillar shape such as a triangular pillar, a square pillar, a pentagonal pillar, and the like, and in particular, the final product may have a regular polygonal pillar structure in order to have a symmetrical structure. In addition, the outer surfaces of the mold 120 may have an elliptic pillar shape. The mold 120 may be manufactured using a metal or a polymer.

Referring to FIG. 2, a pipe forming material 10 is provided on the outer surfaces of the molds 120. The pipe forming material 10 may be directly provided to the outer surface, or may be directly provided to the separate member in a state where a separate member is disposed on the outer surface.

5 and 6, the rotating means 130 includes linear bearings 135. The linear bearings 135 smoothly move forward and backward of the molds 120 and simultaneously rotate the molds 120 with the rotation shaft 110. The linear bearings 135 are spaced apart from each other along the longitudinal axis direction (X-X direction) between the mold 120 and the rotation shaft 110.

A groove 128 is formed in the guide portion 129 of each of the molds 120 along the longitudinal axis direction (XX direction) on an inner surface facing the rotation shaft 110. The linear bearing 135 And a bearing housing 136 and balls 137. The bearing housing 136 is coupled to the rotating shaft 110 to surround the outer circumferential surface of the rotating shaft 110, and rotates together with the rotating shaft 110. The balls 137 are supported by the bearing housing 136 and are arranged to have relative rotation and relative linear motion within each groove 128.

The moving unit 140 moves the mold 120 back and forth along the longitudinal axis direction (X-X direction). That is, the moving unit 140 sequentially moves the mold 120 in the longitudinal direction (X-X direction) according to the circumferential arrangement order. Thereafter, when the mold 120 performs one rotation of rotation about the longitudinal axis, the moving unit 140 automatically retracts the mold 120 to the original position sequentially.

2 to 4, the moving means 140 includes a cam member 145 and a cam plate 146. The cam member 145 is fixed to the frame portion 150. The cam member 145 includes a circular tubular cam portion 147a into which the front portion of the rotary shaft 110 is inserted, and the front portion of the rotary shaft 110 is inserted to be rotatable relative to the cam member 145. have.

A closed curved cam surface 148 is formed on the outer surface of the cam portion 147. The cam surface 148 includes a first groove 148a and a second groove 148b. The first groove portion 148a extends from the first position P1 of the outer circumferential surface of the cam portion 147 to the second position P2 in a spiral shape with respect to the longitudinal axis direction (XX direction), and has a groove structure. have. The second groove 148b extends from the second position P2 to be connected to the first position P1 and has a groove structure.

Each cam plate 146 is fixed to the front portion of each mold 120, respectively. The cam plate 146 moves the mold 120 back and forth while the roller 146a moves along the cam surface 148 when the mold 120 rotates together with the rotation shaft 110. This will be described in more detail as follows. The roller 146a of the cam plate 146 is guided along the first groove 148a to move forward the mold 120 to which it is fixed. Thereafter, while the roller 146a of the cam plate 146 is guided along the second groove 148b, the mold 120 to which it is fixed is moved backward. As described above, while the rotation shaft 110 is rotated once, the mold 120 performs the forward movement while making one rotation with the rotation shaft 110, and then performs the backward movement to return to the original position again.

Referring to FIG. 6, while the rotation shaft 110 rotates once, the position of the longitudinal axis direction (XX direction) of the six molds 121, 122, 123, 124, 125, and 126 is schematically Is shown. Hereinafter, the term 'former 120' is used as a term generally referring to one of six molds 121, 122, 123, 124, 125 and 126.

The first mold 121 is in the original position, the second mold 122 is advanced than the first mold 121, and the third mold 123 is advanced than the second mold 122. The forward position of the fifth mold 125 is the largest, and the sixth mold 126 is in the backward position to return to the original position. That is, the cam plates 146 of the first mold 121 to the fifth mold 125 are positioned to correspond to the first groove 148a, and the cam plate 146 of the sixth mold 126 is It is positioned to correspond to the second groove 148b.

4, the ends of the form 120 are shown. As described above, since the deviation of the forward position between the mold 120 occurs, it can be seen that the end of the mold 120 is stepped deviation along the circumferential direction.

Referring to FIG. 5, rolling bearings 160 are shown. If the length of the mold 120 is longer, the likelihood of sagging of the mold 120 increases. Although the linear bearings 135 may also support the molds 120, there is a problem in that the price of the linear bearing 135 is high. Therefore, the linear bearings 135 are arranged at equal intervals with respect to the longitudinal axis direction (XX direction), and the rolling between the rear tooth bearings 135 or the foremost part or the rearmost part of the mold 120 is performed. Bearings 160 are installed.

Hereinafter, the operation of the continuous pipe manufacturing apparatus 100 using the collect mold 120 according to FIGS. 2 to 7 will be described. First, a driving source for driving the rotating shaft 110 is operated, the rotating shaft 110 is rotated. The mold 120 rotates integrally with the rotation shaft 110 by the rotation of the rotation shaft 110, and the cam plates 146 advance the mold 120 in the longitudinal axis direction (XX direction). Or reverse. While the rotary shaft 110 is rotated once, each mold 120 is advanced and then returned to its original position. While the rotation shaft 110 rotates, the pipe forming material is provided on the molds 120, and the pipe forming material is stacked on the molds 120. The pipe forming material stacked on the molds 120 is continuously advanced in the longitudinal axis direction (X-X direction) by the molds 120. Subsequently, the pipe forming material (not shown) is heated by a heater (not shown) and then cured, and after being ground, a pipe-shaped product is cut to a length suitable for a user's request by a cutter (not shown). (Not shown) is produced.

As described above, by the rotation and forward and backward movement of the mold 120, the tubular product (not shown) is continuously produced. The above has described the operation of the mold 120 for the case where the mold 120 is a collect type.

Meanwhile, referring to FIGS. 1 and 8, the structure 230 includes a frame 231 and a plurality of bobbins 233. The frame 231 is disposed in an annular shape to surround the mold 120. At this time, the inner circumference of the frame 231 having an annular shape has a larger diameter than the outer circumference of the mold 120 so that the inner circumference of the frame 231 and the outer circumference of the mold 120 are spaced apart from each other.

The bobbins 233 are spaced apart from each other and fixed along the circumferential direction of the frame 231, and are provided to provide the material 10. In order to smoothly provide the material 10 in the frame 231, the frame 231 does not form an inner circumferential surface, but an inner circumference is completely open, or the frame 231 forms an inner circumferential surface, but the upper circumferential surface is not formed. It is also possible to form a through-hole in which the material 10 is discharged to the outside.

Referring to FIG. 8, the bobbins 233 are arranged in plural along the circumferential direction of the structure 230 to provide the material 10 in multiple directions. According to this, it is possible to increase the pipe thickness and reinforcement by providing a large amount of the material 10 at a time in a short time, and can be adjusted to make the density of the material 10 more uniform with respect to the entire circumferential direction of the pipe.

As imagined, the structure 230 controls the rotation speed and the rotation direction of the frame 231 so that the material 10 provided from the bobbins 233 is wound or wound around the mold 120. By controlling the angle of the losing, it is possible to produce pipes having various types of cross sections, thereby increasing the tensile strength and strength of the pipe.

To this end, referring to FIG. 1, the structure 230 is configured such that two or more layers of a plurality of material layers are wound in multiple directions at different angles or at different angles with respect to a cross section of a pipe to be manufactured. Plural pieces are installed at intervals set along the longitudinal direction of the 110.

1 illustrates an example in which three structures 230 are installed on the rotation shaft 110 to form three material layers 11, 12, and 13. The wound direction of the first layer 11 by the first structure 230 and the second layer 12 by the second structure 230 are different from each other. The second layer 12 by the second structure 230 and the third layer 13 by the third structure 230 also have different winding directions. Of course, the winding angle is also adjustable for each layer (11, 12, 13).

In addition, the direction in which the material 10 is wound is determined according to the rotation direction of the structure 230 relative to the rotation axis 110, and the angle in which the material 10 is wound is a structure compared to the rotation axis 110 ( 230 is determined according to the rotation speed. Of course, the + or-value of the velocity value means the forward or reverse rotation of the structure 230, so that the positive or negative value of the velocity of the structure 230 and the winding of the material 10 according to the magnitude of the velocity Direction and angle can be adjusted together.

That is, the manufacturing apparatus 100, by adjusting the rotational direction or rotational speed of the frame 231, by using a relative speed between the rotational speed of the rotary shaft 110 and the rotational speed of the structure 230, It is possible to adjust the direction or angle in which the material 10 is wound. Hereinafter, the principle in which the direction or angle of the winding of the material 10 is adjusted will be described in detail with reference to FIGS. 8 and 9 and the example of Table 1. FIG.

TABLE 1

  example  Axis of rotation Case A: Material (Conditions: Rotation axis rotation, Structure stop)  Structure Case B: Material (Conditions: Rotation axis rotation, Structure rotation)  Rotation speed (rmp1), direction  Speed wound, direction  Rotation speed (rpm2), direction  Winding speed, direction One   + A, forward   -A, reverse + A, forward 0A, stop 2 -A, reverse -2A, reverse 3 0A, stop -A, reverse 4 + 2A, forward A, forward 5 -2A, reverse -3A, reverse 6 + 2A, forward -2A, reverse + A, forward -A, reverse 7 -A, reverse -3A, forward

Here, with respect to condition A, if the rotation direction of the rotation shaft 110 is in the forward direction, it is a common matter that the material 10 wound about the rotation shaft 110 is wound in the opposite direction in the opposite direction. In addition, if the speed value is a positive value, the positive direction is shown; if the speed value is a negative value, the reverse direction is shown.

In case A, only the rotating shaft 110 is rotated at a constant speed and the structure 230 is not rotated at all, which corresponds to the case of a continuous pipe apparatus that does not conventionally use the structure 230. In this conventional case, when the material 10 is wound on the mold 120, it is wound only at a single angle in a single direction, so that the tensile strength, strength, etc. of the pipe with respect to a direction or angle other than the single direction or angle to be wound are inferior. There are disadvantages.

In the case of Example 1, when the rotating shaft 110 rotates by A speed in the forward direction, the material 10 is wound at A speed in the reverse direction. However, as the structure 230 rotates by the A speed in the forward direction, the A speed in the forward direction is applied to the material 10 wound at the A speed in the reverse direction opposite to the rotation shaft 110, so that the material 10 is shaped. It will be in the state which is not wound up on 120 at all. This first case is only an example for explaining the principle of the present invention, and is not actually used during pipe forming.

In the case of Example 2, the rotation shaft 110 is rotated at the A speed in the forward direction, the structure 230 is rotated at the A speed in the reverse direction, the material (10) is wound at the A speed in the reverse direction opposite to the rotation axis 110 In the same direction, the winding speed is accelerated as the A speed is further applied in the same reverse direction, so that the material 10 is wound in the reverse direction at a total speed of 2A.

In the case of Example 3, the rotation shaft 110 is rotated at the A speed in the forward direction, the structure 230 is a conventional case that does not rotate at all, the material 10 is wound at the A speed in the reverse direction.

In the case of Example 4, the rotation shaft 110 is rotated at a speed A in the forward direction, the structure 230 is rotated at a speed of 2A in the forward direction, the material (10) wound in the opposite direction opposite to the rotation axis 110 (10) ) Is again applied in the opposite forward direction by a speed of 2 A, whereby the workpiece 10 is wound in the forward direction at a total A speed.

In the case of Example 5, the rotating shaft 110 is rotated at a speed A in the forward direction, the structure 230 is rotated at a speed of 2A in the reverse direction, the material 10 is wound at the speed A in the reverse direction opposite to the rotation axis 110 In the same reverse direction, the winding speed is accelerated as the speed is further increased by 2A, so that the material 10 is wound in the reverse direction at a total speed of 3A.

In the case of the remaining examples 6 and 7, and also can be inferred based on the above-described example, detailed description thereof will be omitted.

Here, regardless of the direction in which the material 10 is wound, as the speed at which the material 10 is wound increases, the winding angle of the material 10 wound on the mold 120 increases for the same time. Referring to Fig. 9, there is shown a cross-sectional example of pipes 20a and 20b manufactured according to the above-described method. In the case of (a), the winding angles of the layers 11a, 12a, and 13a are about 45, and in the case of (b), the winding angles of the layers 11b, 12b, and 13b are (a). If greater than In particular, in the case of the second layer 12b in (b), the speed at which the material 10 is wound is increased so much that the angle at which the material 10 is wound is almost 90 degrees.

Based on the above examples, by adjusting the rotational speed and direction of the structure 230 in contrast to the rotation of the rotary shaft 110, the direction in which the material 10 is wound or the angle to be wound can be adjusted freely Able to know. Therefore, for each material layer forming the pipe, it is possible to adjust the winding in different directions or angles for each layer. In addition, according to the adjustment, by varying the direction, the angle is wound for each layer of the pipe to be produced, there is an advantage that can improve the tensile force, strength, reinforcement and the like of the pipe.

Referring to FIG. 1, the pipe produced as described above is cured by a heater 250 later, and then cut into a length suitable for a user's request through a cutter 260, and thus a tubular product (eg, FIG. 9). (A), (b)) are produced. Of course, the material 10 is resin-treated in advance and then cured. To this end, the material layers forming the pipe are formed by being impregnated and cured in the resin. There are three examples of this approach. First, a method of forming a pipe by providing the material 10 already treated with resin from the bobbin 233. Second, after the resin is applied or sprinkled on the surface of the mold 120, the material 10 is wound on it, and then hardened to form a pipe. Third, a pipe may be formed by applying or sprinkling a resin on the material 10 wound on the mold 120 and curing the resin.

In conclusion, the final manufactured pipe is formed by being impregnated and cured in a resin in a state in which the long fiber material 10 is wound about the circumferential direction of the pipe to be manufactured, and a plurality of material layers are formed for the cross section of the manufactured pipe. Wherein at least two of the material layers are formed by being wound in multiple directions in different directions or at different angles. In this case, as described above, the material 10 may include glass, carbon, or aramid.

Meanwhile, referring to FIGS. 1 and 8, the continuous pipe manufacturing apparatus 100 includes a driver 240 for rotating the frame 231. The driving unit 240 includes a roller driving source 241, a rotating roller 242, a support roller 243, and a controller 244.

 The roller driving source 241 may use a means such as a motor to provide a rotational force to the rotary roller 242. The roller drive source 241 uses a means such as a belt 245 to provide the rotational force. The rotary roller 242 is inserted into one side of the guide groove 232 formed along the outer circumferential surface of the frame 231, and friction with the frame 231 according to the operation of the roller driving source 241 to the frame 231 Rotate). In addition, the support roller 243 is inserted into the other side of the guide groove 232, when the rotary roller 242 is rotated by the friction of the frame 231 while supporting the rotation state of the frame 231 do. The controller 244 performs forward or reverse rotation control of the roller drive source 241 and rotation speed control of the roller drive source 241. To this end, the controller 244 may be provided with an input unit (not shown) that receives a control signal for the rotation control and the speed control from a user.
