Description

[0001] DESCRIPTION

[0002] TWO TROLLEY HELICALLY WOUNDED GLASS FIBER REINFORCED POLYESTER PIPE PRODUCTION MACHINE

[0003] Technical Field

[0004] The invention relates to glass fiber reinforced polyester (GRP) pipe production machine, where GRP pipes are produced by helical winding method.

[0005] The invention particularly relates to the GRP pipe production machine, which can wind twice as fast or produce two different types of pipes at the same time by means of its ability to wind on both sides with trolleys placed on both sides.

[0006] Prior Art

[0007] Today, GRP (Glass Fiber Reinforced Polyester) pipes are currently produced in the world by continuous fiber winding method, centrifugal method, pultrusion method and helical winding method.

[0008] The continuous fiber winding method comprises mandrels mounted on the main shaft of the production machine and a continuous tape wrapped on beams mounted on the mandrels to form the cylindrical structure. As the beams rotate, the tape moves axially and the main and auxiliary materials that will form the composite structure are applied onto the mandrel. While the filling material and binder, which are the materials that form the composite structure, are poured onto the tape from above, the production is completed by wrapping the fibers coming from one side onto the tape.

[0009] In GRP pipe production with the centrifugal method, the hollow mold is rotated, resin and glass fiber pieces are placed in the rotating mold, and due to the centrifugal force formed by the rotating mold, glass fiber and resin are plastered to the inner surface of the mold and take the shape of a pipe. Since the inside of the mold forms the outer surface of the pipes, the outer surface is very smooth, and the inner surface is rough. Since the roughness in the inner surface forms resistance in the water flowing through the pipe, it may cause selection of larger diameters and therefore cost increases.

[0010] Pultrusion method is the production method in which GRP material is produced by passing resin- coated glass fibers through a shaped-inside mold. In this type of production, the fibers are densely along the pipe. Large diameter pipes are difficult to produce. Since the number of surrounding fibers is very low, their compressive strength is low.

[0011] In the helical winding method used in the prior art, a single trolley is used in a machine and one type of pipe can be produced at the same time. Also, the preparation process takes a long time. In the state of the art, producing a single pipe at the same time causes the production capacity to be low, which causes the production cost to increase.

[0012] As a result of the search carried out in the literature, various configurations of the mentioned GRP pipe production machines emerge. One of them is the utility model titled “Glass fiber reinforced polyester pipe production system” with application numbered TR2008 / 05832. In the summary of the invention with classification class B29D 23 / 00, the following statement is included: ” This invention relates to the glass fiber reinforced polyester pipe production system that enables the production of glass fiber reinforced polyester pipes used in backup and tertiary pipelines for pressurized or nonpressurized irrigation water transmission and distribution, in drinking water transmission and distribution networks, in main and secondary collectors in sewage systems, in the transmission of all kinds of waste water, in the use of sea water as cooling water in power plants, in the transmission of clean and waste water under the sea, in the transmission of chemicals in chemical factories and in the transmission of water containing chemicals obtained from thermal sources, wherein; it consists of mainly main machine body, main machine bottom and feeding platforms, mandrel, mandrel bearing group, main mandrel motor, steel tape, steel tape guiding groups, polyester main tanks and pumping group, polyester conveying and dosing group, polyester conveying pipelines, main sand tank and conveying group, sand feeding group, fiber feeding system, infrared heating system, pipe cutting machine, hydraulic tables, hydraulic table top roller groups, pipe carrier groups, pipe end chamfering and adjustment group, sleeve fitting machine, pipe pressure testing machine, pressure water pool, pipe fittings manufacturing machine, polyester, sand, glass fiber, catalyst chemical, product (pipe), test cylinder and test head.

[0013] Another example of the mentioned configuration is the patent with application number TR2011 / 00950, titled “Fast pp, pe and glass fiber reinforced pp pipe production line and pipe production method.” In the summary of the invention with classification class B29D 23 / 00, the following statement is included: “This invention consists of PP or PE extruder, PP or PE or glass fiber reinforced PP mold, PP or PE or glass fiber reinforced PP calibrator, vacuum tank and cooling unit-1 , glass fiber extruder, vacuum tank and cooling unit-2, pipe puller, pipe cutter, pipe knocker and pipe winder; it is a fast PP, PE and glass fiber reinforced PP pipe production line, wherein; it comprises a dried cold air unit and an oil heating-cooling unit.”

[0014] In the applications mentioned above, one pipe can be produced. Therefore, these applications can be shown as examples of the disadvantages mentioned above.

[0015] As a result, improvements are being made in GRP pipe production machines in parallel with the developing technology, therefore new structures are needed that will eliminate the disadvantages mentioned above and bring solutions to existing systems. Object of the Invention

[0016] The invention relates to GRP pipe production machines, which, unlike the embodiments used in the present art, developed to solve the mentioned disadvantages and bring some additional advantages.

[0017] The object of the invention is to double the production speed by feeding the fiber from two sides with two trolleys.

[0018] Another object of the invention is to make it possible to produce pipes of different diameters and features at the same time. For example, while one of the trolleys will feed a rotating mold, the other trolley will feed fiber to two other molds rotating together. In this way, it will be possible to produce pipes of different diameters and features at the same time.

[0019] Another object of the invention is to enable the production of pipes of different lengths by means of the movability of the support leg platform.

[0020] The structural characteristics and all the advantages of the invention will be understood more clearly by means of the drawings given below and the detailed description written with references to these drawings. For this reason, the evaluation needs to be made by taking these drawings and detailed description into consideration.

[0041] Detailed Description of an Example of the Invention

[0042] In this detailed description, the preferred embodiments of the GRP pipe production machine (1), which is subject of the invention are described only for a better understanding of the subject and without any limiting effect.

[0043] Structure principle:

[0044] The GRP pipe production machine (1 ) comprises mandrel rotating motor system (10), mold gripping and rotating mandrel (20), pipe production mold (30), fiber feeding unit (40), support leg platform (50) and rails (60).

[0045] Said mandrel rotating motor system (10) is the system that provides power for the mold gripping and rotation of the rotating mandrel (20). There are a total of two rotation motor systems in the system. One mandrel rotates by being driven by one motor system, and the other two mandrels by being driven by the other motor system. The shaft (11), which is connected to the motors in the mandrel rotating motor system (10), is also connected to the pipe production molds (30). It ensures that the rotational motion coming from the motor is transmitted to the pipe production molds (30).

[0046] The mold gripping and rotating mandrel (20) is the mechanism that enables the shaft (11) at the end of the pipe production mold (30) to be tightened and gripped and transfers the movement of the motor to the shaft.

[0047] The pipe production mold (30) is the mold on which the materials that are connected to the shaft (11) and will rotate and form the composite structure are applied. 3 pieces are positioned on top of each other. Rails (60) are placed parallel to both sides of the GRP pipe production machine (1). Fiber feeding units (40) are placed on the trolleys (70) that will travel on these rails (60). Fiber feeding unit (40) consists of inlet fiber separator (41), inlet fiber combs (42), resin tank (43), resin scraper (44), resin fiber comb 2 (45), resin fiber comb 1 (46) and fiber collection ring (47). These elements are shown in figure 1.

[0048] Said inlet fiber separator (41) is a perforated structure that allows the fibers coming from the bobbins to be separated from each other so that they do not get tangled and are fully wetted with resin. The inlet fiber combs (42) ensure that the fibers coming from the inlet fiber separator (41 ) enter the resin tank (43) without mixing with each other. Said resin tank (43) is the chamber containing the resin that the fibers need to be wetted.

[0049] The resin scraper (44) is used to ensure that the fibers coming out of said resin tank (43) are thoroughly wetted with resin and the excess resin is scraped off from the fibers. Resin fiber comb 2 (45) and resin fiber comb 1 (46) are used to prevent the resin-wetted fibers from clumping as they enter the fiber collection ring (47) and to ensure smooth fiber flow. The fibers can pass through these combs and be conveyed to the fiber collection ring (47) without clumping or mixing. Said fiber collection ring (47) is the element that ensures that the resin-wetted fibers are held together and properly wound in the pipe mold for application on the pipe production mold (30). All of these elements mentioned are present in both trolleys (70).

[0050] The support leg platform (50) keeps the above-mentioned pipe production molds (30) standing. Pipe production molds (30) are connected to the support leg system (51) located on the inside. The support leg platform (50) is portable. It will allow the production of pipes of different lengths by moving them back and forth.

[0051] Glass fibers coming from the bobbins on the shelves are passed through the input fiber separators (41 ) and transferred to the input fiber comb (42). Here, the combed fibers enter the resin tank (43) and are wetted with resin. The wetted fibers pass through resin scrapers (44) to be separated from excess resin. The fibers from which excess resin has been removed come to the resin fiber comb 2 (45) and the scraped fibers are combed and separated from each other. The combed fibers are divided into three for pipe production and come to Resin Fiber Comb 1 (46). Here, the fibers are combed for the last time and conveyed to the fiber collection ring (47). The fibers held together by this ring begin to be wound helically on the pipe production mold (30). Pipe production takes place with glass fibers wrapped around the pipe production molds (30) while rotating by means of the shaft (11 ).

[0052] In Figure 2, there is the top view of the pipe production machine (1). As can be seen, there are two trolleys (70) in the system, one on the rails (60) placed on both sides of the pipe production molds (30). These trolleys (70) continuously move back and forth on the rails (60), parallel to the pipe axis. Meanwhile, the pipe production mold (30) rotates. In this way, it enables the resin-wetted fibers to be wrapped on the pipe production mold (30). In addition, by changing the reciprocating movement speed of the carriage (70) and the rotation speed of the pipe production mold (30), different angle fiber winding is performed on the pipe production mold (30). There are carriages (70) on both sides of the pipe production molds (30). Since two trolleys (70) feed glass fiber from two different sides at the same time, production time is halved. If desired, since there are two trolleys (70) in the system and two rotation motors, one trolley can feed one pipe production mold (30), and the other trolley (70) can feed the other two pipe production molds (30). Thus, pipes with two different features (different diameters, different thicknesses, etc.) can be produced at the same time.
