Description

Technology Field

[0001] The present invention relates to a filament winding device for winding an axis center, and more specifically, to a filament winding device for winding an axis center that can improve the strength of filament winding by widening the winding range, as well as smoothly supply filament while maintaining a certain degree of tension and preventing sagging of the filament. Background Technology

[0003] Generally, water tanks are installed to ensure a smooth supply of drinking and water for general use in buildings of a certain size or larger, such as large office buildings, public housing, factories, and private homes; they are often constructed using a prefabricated method so that their volume can be varied according to the scale of the building.

[0004] These water tanks are typically manufactured separately using materials such as steel plates, FRP, stainless steel, GRP, and ENM, and are installed outdoors or underground for use.

[0005] Among these, GRP (Glass Fiber Reinforced Plastics) and ENM (Elvan Nephrite Marlle) are materials that are lightweight yet highly durable. These GRP and ENM are manufactured into panels (sheets) of a specific shape by SMC (Sheet Molding Compound) compression molding, which is one of the molding techniques for shaping products.

[0006] Panels manufactured by the aforementioned SMC (Sheet Molding Compound) compression molding not only exhibit excellent mechanical properties but also have excellent corrosion resistance and moldability, so they are gaining attention as new structural and functional materials. As a result, water tanks constructed by joining SMC panels together to form a square box shape are widely used.

[0007] In particular, as described above, prefabricated water tanks assembled at the installation site using SMC panels are on the rise in use because they not only facilitate installation by assembling the SMC panels (unit panels) but also allow for easy adjustment of the tank size.

[0008] However, for prefabricated water tanks, it is crucial to have a structure capable of withstanding high water pressure; since the panels assembled on the sides bear the greatest pressure, they are reinforced by connecting tie rods between opposing panels.

[0009] Here, tie rods are generally used to connect corner fittings and turnbuckles of containers to prevent tilting or collapse accidents during maritime transport on container ships, but they can also be used as tension bars to support water pressure in prefabricated water tanks.

[0010] Accordingly, tie rods must be safely designed to withstand high water pressure.

[0011] In order to meet these regulations, high-strength alloy steel materials such as SCR4, SCM4, and SNCM8 are generally used. However, for long products reaching 5m in length, the weight per unit reaches 20 to 25 kg, and for products 2.5 to 3m in length, it reaches 10 to 15 kg. Consequently, the process of transporting, installing, and dismantling these products causes not only worker fatigue but also the risk of safety accidents, leading to reduced work efficiency and problems such as avoidance of work.

[0012] Examples of inventions developed to improve upon the above-mentioned problems include the "Tie rod made of composite material and method of manufacturing the same" (hereinafter referred to as prior art) of Registered Patent No. 10-1669582.

[0013] The prior art consists of a composite material wrapped around a central core and a grooved thimble by winding high-tensile-strength continuous fibers around the outside, and metal parts in specific areas where the load is concentrated.

[0014] However, when manufacturing using existing continuous fiber winding methods, including prior art, it is necessary to supply multiple strands of continuous fiber simultaneously; in this case, there was a problem where the continuous fibers supplied in multiple strands sagged along the supply direction due to their own weight. Prior art literature

[0038] Hereinafter, preferred embodiments of the present invention will be described with reference to the attached drawings.

[0040] First, FIG. 1 is a front conceptual diagram illustrating the structure of a first unit (100), which is a main part of a filament winding device that winds an axis center according to one embodiment of the present invention.

[0041] Here, FIG. 2 is a conceptual diagram illustrating various embodiments showing the movement trajectory (331) of a delivery eye (330) with respect to a first unit (100), which is a main part of a filament winding device winding an axis center according to one embodiment of the present invention.

[0042] At this time, FIG. 3 is a side conceptual diagram illustrating the overall configuration of a filament winding device winding an axis center according to one embodiment of the present invention.

[0043] And, FIG. 4 is a planar conceptual diagram illustrating the overall configuration of a filament winding device winding an axis center according to one embodiment of the present invention.

[0044] In addition, FIG. 5 is a perspective conceptual diagram illustrating the overall structure of the fourth unit (400) and the fifth unit (500), which are the main parts of a filament winding device that winds an axis center according to one embodiment of the present invention.

[0045] In addition, FIG. 6 is a side conceptual diagram illustrating the overall structure of the fourth unit (400) and the fifth unit (500), which are the main parts of a filament winding device that winds an axis center according to one embodiment of the present invention.

[0046] For reference, in FIGS. 3 and 4, the transparent thick arrow indicates the direction in which the filament (211) is supplied, in FIG. 5, the filament (211) is supplied diagonally from the upper right to the lower left, and in FIG. 6, the filament (211) is supplied from the right to the left.

[0048] First, let us look at the movement trajectory (331) of the delivery eye (330) with reference to FIG. 1 and FIG. 2.

[0049] Conventional filament winding involves winding the outer surface of a rotating mandrel around an axis; since an axis exists for rotation, the delivery eye's filament cannot enter the center of the axis, resulting in a structure where filament winding at the center of the axis is impossible.

[0050] In contrast, the present invention can widen the winding range of the filament (211) by allowing the filament (211) of the delivery eye (330) to pass through the first and second cut sections (131, 141) of the first and second winding guide jigs (130, 140) coupled to the winding axis, that is, the first and second rotation axis (110, 120), and pass through a virtual line (see dashed line in FIG. 2) penetrating the center of the first and second rotation axis (110, 120).

[0051] Therefore, the winding strength of the filament (211) can be improved.

[0052] That is, the present invention may provide first and second winding guide jigs (130, 140) formed in an overall 'C' shape by forming first and second cut sections (131, 141) so that a movement trajectory (331) of the delivery eye (330) can be formed to allow the delivery eye (330) to pass through in the axial direction as in FIG. 2(a).

[0053] Here, we intend to examine the movement trajectory (331) of the delivery eye (330) with reference to FIGS. 2(b) to FIGS. 2(d).

[0054] First, with the first and second rotation axes (110, 120) fixed, as shown in FIG. 2(b), the delivery eye (330) passes through the center (see dashed line) of the first and second rotation axes (110, 120) (Y-axis direction) and can repeat winding between the first and second winding guide jigs (130, 140) as shown in ① to ④ (X-axis direction).

[0055] Then, as shown in FIG. 2(c), the delivery eye (330) moves ① to the center of the first rotation axis (110) (Y-axis direction), ② the first rotation axis (110) rotates 180 degrees (Z-axis direction), ③ the delivery eye (330) returns to its original position, that is, the position before moving to the center of the first rotation axis (110) (Y-axis direction), and ④ moves by the length of the product to be manufactured (X-axis direction).

[0056] Continuing, the delivery eye (330) moves ⑤ back to the center of the first and second rotation axes (110, 120) (Y-axis direction), then ⑥ the second rotation axis (120) rotates 180 degrees (Z-axis direction), then ⑦ the delivery eye (330) returns to its original position, that is, the position before moving to the center of the second rotation axis (120) (Y-axis direction), and then ⑧ returns along the distance traveled by the length of the product to be manufactured (X-axis direction).

[0057] That is, the operations ① to ⑧ illustrated in Fig. 2(c) can be repeated.

[0058] In addition, the delivery eye (330) can apply the angle and twist of the filament (211) to a specific position or section by performing operations ② and ④ of FIG. 2(b) and operations ④ and ⑧ of FIG. 2(c) at the same time rotating the first and second rotation axes (110, 120) as in FIG. 2(d).

[0059] For example, the delivery eye (330) can simultaneously perform the first and second rotation axes (110, 120) rotating in the Z-axis direction, such as 180 degrees, 360 degrees, 540 degrees, 720 degrees, based on a specific position while moving linearly in the X-axis direction or stopped after moving linearly, as in operations ② and ④ of FIG. 2(b) and operations ④ and ⑧ of FIG. 2(c).

[0060] Therefore, it will be possible to implement specific angles and twist shapes at specific locations or sections, as well as to create and implement various shapes through the movement distance and speed in the X-axis direction and the rotation angle and rotation speed in the Z-axis direction.

[0062] Meanwhile, as shown in FIGS. 3 and 4, the present invention may apply an embodiment of a structure in which a filament (211) is supplied from a second unit (200) toward a first unit (100) through a delivery eye (330) of a third unit (300).

[0070] Additionally, the third unit (300) may include a first guide rail (303) that interconnects the third support column (301) and the fourth support column (302) and is parallel to the installation surface (600), and a first mover (310) that can reciprocate along the first guide rail (303).

[0071] Additionally, the third unit (300) may include a second guide rail (304) formed vertically in an up-and-down direction perpendicular to the installation target surface (600) on the first mover (310), and a second mover (320) capable of reciprocating along the second guide rail (304).

[0072] Additionally, the third unit (300) may include a plurality of delivery eyes (330) that guide a plurality of filaments (211), which are formed along the upper and lower directions of the second mover (320) and guided through a pass guide (230), to the core rod (150) and the first winding guide jig (130) and the second winding guide jig (140), respectively, which are spaced apart in upper and lower stages.
