Of course, depending on other conditions, the form of the fiber 14 is not limited to these.

  The fiber tension measuring device 20 has a function of measuring the tension applied to the fiber 14 delivered from the fiber supply device 12. As the fiber tension measuring device 20, a tension measuring device generally used for measuring the tension of the fiber 14 can be used.

  The resin impregnation device 22 has a function of impregnating the fiber 14 whose tension has been measured by the fiber tension measurement device 20 with resin. FIG. 2 is a schematic view showing the configuration of the resin impregnation apparatus 22, FIG. 2A is a schematic view of the resin impregnation apparatus 22 viewed from the side, and FIG. It is the schematic diagram seen from the upper surface.

  As shown in FIG. 2A, the resin tank 24 has a function of storing a resin for impregnating the fibers 14 and is disposed in the resin impregnation apparatus 22. As the resin, for example, an epoxy resin, which is a thermosetting resin, can be used. Of course, depending on other conditions, the thermosetting resin is not limited to an epoxy resin, and other thermosetting resins such as a phenol resin can be used. In the resin tank 24, an epoxy resin mixed with a curing agent, a solvent, or the like is stored in a liquid state. The resin tank 24 is provided with a heating device such as a heater (not shown) having a function of heating the resin and adjusting the resin temperature in order to adjust the viscosity of the resin. The resin tank 24 is provided with a resin temperature sensor such as a thermocouple (not shown) having a function of measuring the resin temperature of the resin stored in the resin tank 24.

  As shown in FIG. 2A, the resin adhesion roller 26 has a function of causing the resin in the resin tank 24 to adhere to the roller surface and then transferring the adhered resin to the fibers 14. It arrange | positions at the resin impregnation apparatus 22. FIG. The resin adhering roller 26 is disposed in the resin impregnation apparatus 22 so that the lower part of the roller is immersed in the resin in the resin tank 24. The resin adhesion roller 26 rotates the roller with a motor or the like in order to transfer and adhere the resin in the resin tank 24 to the fibers 14 pressed by the first tension roller 28 and the second tension roller 30. A rotating shaft 32 is provided.

  The resin adhering roller 26 may be provided with a blade (not shown) having a function of preliminarily adjusting the amount of resin adhering to the roller surface. The blade is arranged with a predetermined distance between the tip of the blade and the roller surface in order to make a preliminary adjustment so that the resin transferred and adhered to the fibers 14 becomes substantially constant. And the space | interval of the front-end | tip of a braid | blade and a roller surface is adjusted using a clearance gauge etc., for example. Such a blade can be made of a metal material such as rubber, plastics or stainless steel.

  As shown in FIG. 2A, the resin impregnation amount adjusting roller 36 is disposed in the resin impregnating device 22 with a gap D having a predetermined width from the resin adhering roller 26, and the resin adhering fibers 34 are arranged. It has a function of adjusting the resin impregnation amount by passing through the gap D. The resin impregnation amount adjusting roller 36 can adjust the resin impregnation amount of the fibers 14 by adhering excess resin removed from the fibers 34 to which the resin has adhered to the roller surface. The resin impregnation amount adjusting roller 36 includes a rotating shaft 35 for rotating the roller by a motor or the like. The size of the resin impregnation amount adjusting roller 36 can be the same size as the resin adhering roller 26. Of course, depending on other conditions, the size of the resin impregnation amount adjusting roller 36 may be different from that of the resin adhering roller 26 and is not limited thereto.

  The predetermined width in the gap D is such that when the fibers 34 with the resin adhered are passed through the gap D between the resin adhesion roller 26 and the resin impregnation amount adjusting roller 36, excess resin in the fibers 34 with the resin adhered is removed. Thus, the thickness is determined to be smaller than the thickness (fiber + resin thickness) of the fiber 34 to which the resin adheres so that the resin content can be adjusted. The gap D between the resin adhesion roller 26 and the resin impregnation amount adjusting roller 36 is reduced to reduce the resin impregnation amount, and the gap D between the resin adhesion roller 26 and the resin impregnation amount adjusting roller 36 is increased. By doing so, the amount of resin impregnation can be increased.

  The gap adjusting device (not shown) has a function of adjusting the gap D between the resin adhering roller 26 and the resin impregnation amount adjusting roller 36 and is disposed in the resin impregnating device 22. An actuator can be used for the gap adjusting device. For example, a servo cylinder or the like can be used as the actuator. The rod of the servo cylinder is connected to the resin adhesion roller 26 or the resin impregnation amount adjustment roller 36 via, for example, a support member. When the servo cylinder rod is connected to the resin impregnation amount adjusting roller 36, the resin impregnation amount adjusting roller 36 is moved up and down by moving the servo cylinder rod up and down, so that the resin adhering roller 26 and the resin impregnation roller are moved up and down. The gap with the amount adjusting roller 36 can be adjusted.

  The resin adhering roller 26 and the resin impregnation amount adjusting roller 36 are preferably rotated in opposite directions with respect to the gap D. This is because when the resin is inserted into the gap between the resin adhering roller 26 and the resin impregnation amount adjusting roller 36, the resin impregnation amount can be more accurately controlled by suppressing the stay of the resin. In FIG. 2A, the resin adhesion roller 26 rotates from the left direction to the right direction with respect to the gap D, and the resin impregnation amount adjustment roller 36 rotates from the right direction to the left direction. And the resin impregnated amount adjusting roller 36 are rotated in opposite directions. Of course, depending on other conditions, the resin impregnation amount adjusting roller 36 can be rotated in the same direction with respect to the resin adhering roller 26. The resin adhesion roller 26 and the resin impregnation amount adjusting roller 36 are preferably rotated at the same rotational speed. Of course, depending on other conditions, the resin adhering roller 26 and the resin impregnation amount adjusting roller 36 may be rotated at different rotational speeds. Further, the resin impregnation amount adjusting roller 36 can be synchronized with the resin adhering roller 26. The rotation speed, rotation direction, and synchronization of the resin adhesion roller 26 and the resin impregnation amount adjustment roller 36 can be controlled by a roller rotation adjustment device (not shown).

  As shown in FIG. 2A, the film thickness detection device 38 has a function of measuring the resin amount of excess resin attached to the resin impregnation amount adjustment roller 36 and removed from the resin attachment roller 26. And is disposed in the resin impregnation apparatus 22. The film thickness detection device 38 is a means for measuring the resin amount by measuring the film thickness of the resin adhering to the resin impregnation amount adjusting roller 36. For the film thickness detection device 38, for example, a non-contact type ultrasonic film thickness meter can be used. Of course, depending on other conditions, the resin amount measuring means is not limited to such a film thickness detecting device 38.

  The film thickness detection device 38 is preferably arranged for each fiber 34 to which resin is attached. For example, as shown in FIG. 2B, when there are three fibers 34 to which resin is attached, three film thickness detection devices 38 are arranged. Further, each film thickness detection device 38 is disposed at the position of the resin impregnation amount adjusting roller 36 corresponding to the position where the fiber 34 to which the resin adheres passes through the gap D, as shown in FIG. Then, as shown in FIG. 2 (A) or FIG. 2 (B), each of the film thickness detection devices 38 uses the resin 34 of the resin adhering to the resin amount of the excess resin removed from the resin adhering roller 26. Can be measured every time.

  As shown in FIG. 2A, the spatula 40 is a resin removing means having a function of removing the resin adhering to the resin impregnation amount adjusting roller 36, and is arranged in the resin impregnation apparatus 22. The spatula 40 is preferably disposed so that the tip of the spatula 40 is in contact with the roller surface in order to remove the resin adhering to the resin impregnation amount adjusting roller 36. The size of the spatula 40 is preferably substantially the same as the width of the roller. Of course, depending on other conditions, the size of the spatula 40 is not limited to this. As the material of the spatula 40, it is preferable to use rubber or plastics in order to suppress damage to the roller surface. Of course, depending on other conditions, the spatula 40 may be made of a metal material such as stainless steel. The resin removing means is not limited to such a spatula 40, and a scraper or the like can also be used.

  Here, as shown in FIG. 2A, the gap D, the film thickness detection device 38, and the spatula 40 are sequentially positioned with respect to the rotation direction of the resin impregnation amount adjusting roller 36. First, in order to measure the film thickness of the resin adhering to the resin impregnation amount adjusting roller 36 by the gap D, the gap D and the film thickness detecting device 38 are The gap D and the film thickness detection device 38 are sequentially positioned. Next, the film thickness detector 38 and the spatula 40 measure the thickness of the resin adhering to the resin impregnation amount adjusting roller 36 with the film thickness detecting device 38 and then the resin adhering to the resin impregnation amount adjusting roller 36. In order to remove the film thickness, the film thickness detecting device 38 and the spatula 40 are sequentially arranged with respect to the rotation direction of the resin impregnation amount adjusting roller 36. The spatula 40 and the gap D are used to remove a new excess resin removed from the resin adhering roller after the resin adhering to the resin impregnating amount adjusting roller 36 is removed by the spatula 40. In order to make it adhere, the spatula 40 and the gap | interval D are located in order with respect to the rotation direction of the resin impregnation amount adjustment roller 36. In FIG. 2A, when the gap D is at a position of approximately 0 degrees with respect to the rotation direction of the resin impregnation amount adjusting roller 36, the film thickness detecting device 38 is at a position of approximately 180 degrees, and the spatula 40 is approximately The gap D, the film thickness detection device 38, and the spatula 40 are sequentially located at the position of 270 degrees. Of course, the gap D, the film thickness detection device 38, and the spatula 40 need only be sequentially positioned with respect to the rotation direction of the resin impregnation amount adjusting roller 36, and are not limited to such positions. Absent.

  1 again, the control device 44 is connected to the fiber tension measurement device 20, the resin temperature sensor disposed in the resin tank 24, the film thickness detection device 38, and the like using lead wires, connectors, and the like. . The control device 44 can also be connected to a gap adjusting device, a roller rotation adjusting device, or the like. The control device 44 has a function of inputting an electrical signal of the tension data of the fiber 14 output from the fiber tension measuring device 20 and controlling the tension of the fiber 14. And the control apparatus 44 has a function which can input the electrical signal of the resin temperature data output from the resin temperature sensor arrange | positioned at the resin tank 24, and can control resin temperature.

  Further, the control device 44 inputs an electric signal of film thickness data output from the film thickness detection device 38, and determines whether or not a predetermined resin amount serving as a reference is attached to the resin impregnation amount adjusting roller 36. It has a function that can be detected. Further, the control device 44 compares the measured resin amount with the reference resin amount, and if the resin amount measured from the film thickness detection device 38 is smaller than the reference resin amount, an abnormal signal is displayed. It has a function that can output. Such a control device 44 can be constituted by, for example, a personal computer (PC). The data logger 46 connected to the control device 44 stores and stores the tension data, resin temperature data, resin amount data, and the like of the fibers 14 described above.

  The filament winding device 48 has a function of winding the fiber 42 impregnated with the resin delivered from the resin impregnation device 22 by winding the fiber 42 around a mandrel 50 (Mandrel) or the like, which is a mold as a winding member or a mandrel. ing. The filament winding device 48 includes a rotation device for winding the fiber 42 impregnated with the resin by rotating the mandrel 50 and the like. Further, the filament winding device 48 can wind the resin-impregnated fiber 42 in the circumferential direction or the axial direction of the mandrel 50 or the like, for example, a hoop winding that winds substantially perpendicular to the rotation axis direction of the mandrel 50 or the like ( It can be wound by helical winding or the like that winds at a predetermined angle with respect to the direction of the rotation axis such as Hopping and mandrel 50. For example, when a high-pressure tank is manufactured using a fiber reinforced composite material, a fiber that is impregnated with a resin by a filament winding device 48 on a resin liner formed of polyamide resin or a metal liner formed of aluminum or the like. 42 can be wound.

  Then, the fiber 42 impregnated with the resin wound around the mandrel 50 or the liner is heated in a resin curing furnace (not shown) to cure the resin and form a fiber reinforced composite material.

  Next, the operation of the fiber reinforced composite material molding apparatus 10 having the above configuration will be described. From the bobbin 16 of the fiber supply device 12, for example, a fiber 14 that is carbon fiber is fed out. The fiber 14 fed out from the bobbin 16 is adjusted to a predetermined tension by the fiber tension adjusting device 18 and sent out from the fiber supply device 12.

  The fiber 14 delivered from the fiber supply device 12 is measured for the tension applied to the fiber 14 by the fiber tension measuring device 20. Here, the tension data of the fiber 14 measured by the fiber tension measuring device 20 is output from the fiber tension measuring device 20 to the control device 44, stored in the data logger 46 and stored. In addition, for example, when a predetermined tension serving as a reference is not applied to the fiber 14, the control device 44 detects an abnormality in the tension and outputs an abnormality signal or the like. Thereby, for example, the fiber-reinforced composite material molding apparatus 10 stops.

  The fibers 14 that have passed through the fiber tension measuring device 20 are sent out to the resin impregnation device 22. In the resin tank 24 in the resin impregnation apparatus 22, a liquid resin, for example, an epoxy resin is stored. The temperature of the resin is measured by a resin temperature sensor such as a thermocouple. The resin temperature data is output from the resin temperature sensor to the control device 44, stored in the data logger 46, and saved. If the resin temperature is not the set resin temperature, for example, the control device 44 detects an abnormality in the resin temperature and outputs an abnormality signal or the like. Thereby, for example, the fiber-reinforced composite material molding apparatus 10 stops.

  The resin adhesion roller 26 comes into contact with the resin stored in the resin tank 24 as the roller rotates, and the resin adheres to the roller surface. Then, the fibers 14 pressed by the first tension roller 28 and the second tension roller 30 come into contact with the resin adhesion roller 26 so that the resin is transferred and adhered.

  When the fibers 34 to which the resin has adhered pass through the gap D between the resin adhesion roller 26 and the resin impregnation amount adjusting roller 36, excess resin of the fibers 34 to which the resin has adhered adheres to the resin impregnation amount adjusting roller 36. Thus, the fiber 14 is impregnated with an appropriate amount of resin. Further, by rotating the resin impregnation amount adjusting roller 36, the film thickness of the resin adhering to the resin impregnation amount adjusting roller 36 is measured by the film thickness detecting device 38, and then the resin is removed by the spatula 40. Then, in the gap D again, resin newly adheres to the resin impregnation amount adjusting roller 36 from which the resin has been removed.

  Here, detection of the resin-impregnated state of the fibers 14 will be described. FIG. 3 is a schematic view showing a resin-impregnated state of the fiber 14, FIG. 3 (A) is a schematic view showing a case where the resin-impregnated state is normal, and FIG. 3 (B) is a case where the resin impregnation is insufficient. It is a schematic diagram which shows.

  When the resin-impregnated state is normal, as shown in FIG. 3A, the thickness of the fibers 34 to which the resin adheres (fiber + resin thickness) is determined by the resin adhesion roller 26 and the resin impregnation amount adjusting roller. It becomes larger than the width (clearance) of the gap D with respect to 36. Since the fibers 14 are pressed by the first tension roller 28 and the second tension roller 30, the resin impregnated amount adjusting roller 36 removes excess resin from the fibers 34 to which the resin has adhered. The removed excess resin adheres to the resin impregnation amount adjusting roller 36. Thereafter, the film thickness of the resin adhered to the resin impregnation amount adjusting roller 36 is measured by the film thickness detecting device 38. Then, the resin film thickness data measured by the film thickness detector 38 is output from the film thickness detector 38 to the controller 44. Then, the control unit 44 compares the measured resin amount with the reference resin amount, and determines that the measured resin amount is normal when it is larger than the reference resin amount.

  When the resin impregnation is insufficient, as shown in FIG. 3B, the thickness of the fiber 34 to which the resin adheres (fiber + the thickness of the resin) is determined by the resin adhesion roller 26, the resin impregnation amount adjusting roller 36, and the like. It becomes smaller than the width (clearance) of the gap D. Therefore, since the resin impregnation amount adjusting roller 36 and the fiber 34 to which the resin is adhered do not come into contact, the resin impregnation amount adjusting roller 36 hardly adheres to the resin. The film thickness data measured by the film thickness detection device 38 is output from the film thickness detection device 38 to the control device 44. Then, the measured amount of resin is compared with the reference resin amount by the control device 44, and when the amount is smaller than the reference resin amount, it is determined that there is an abnormality. Thus, for example, the fiber reinforced composite material molding apparatus 10 Stop.

  The fiber impregnated with resin passes through the second tension roller 30 and is then sent out to the filament winding device 48. The fiber impregnated with the resin is wound around the mandrel 50 or the liner of the high-pressure tank by a filament winding device 48 by hoop winding or the like. Thereafter, the fiber 42 impregnated with the resin wound around the mandrel 50 or the liner is heated in a resin curing furnace to cure the resin and form a fiber reinforced composite material.

  As described above, according to the fiber reinforced composite material molding apparatus having the above-described configuration, even when the resin is insufficiently impregnated, such as when the fiber is impregnated with a resin amount smaller than the resin amount planned or when the fiber is not impregnated with the resin at all. By measuring the amount of excess resin adhering to the resin impregnation amount roller by a resin amount measuring means such as a film thickness detecting device, it is possible to detect the impregnation of the resin more quickly. Further, by adopting such a configuration, the resin impregnation and the resin amount adjustment are completed on the roller, and the shortage of the resin amount can be detected in the resin impregnation apparatus, so that an abnormality can be detected instantaneously. it can.

  According to the fiber reinforced composite material molding apparatus having the above configuration, the resin amount measuring means is attached to the resin impregnation amount adjusting roller by the film thickness detection device, and the resin amount of the excess resin removed from the resin adhesion roller is removed. Since the measurement is a non-contact detection method with respect to the resin-impregnated fiber, the resin impregnation amount can be managed without adversely affecting the resin impregnation amount of the fiber and without increasing the number of manufacturing steps.

  According to the fiber reinforced composite material molding apparatus having the above configuration, the resin impregnation amount of the fiber can be adjusted more accurately by rotating the resin adhering roller and the resin impregnation amount adjusting roller in opposite directions with respect to the gap. It is possible to detect insufficient resin impregnation. Further, by rotating the roller in the reverse direction, there is no fear that the resin adhering to the resin impregnation amount adjusting roller hangs down on the fiber after the resin amount adjustment, and the resin amount can be controlled appropriately.

  Further, according to the fiber reinforced composite material molding apparatus having the above configuration, the resin impregnation is insufficient due to, for example, constantly monitoring the amount of excess resin removed by the gap between the resin adhesion roller and the resin impregnation amount adjusting roller. Before the fiber is wound around a mandrel or the like, it is possible to detect an insufficient impregnation of the resin. And at the time of detecting the shortage of impregnation, the fiber-reinforced composite material molding apparatus can be stopped, for example, so that the fiber with insufficient resin impregnation can be prevented from being wound. Therefore, according to the said fiber reinforced composite material shaping | molding apparatus, a fiber can be more uniformly impregnated with resin and a fiber reinforced composite material can be shape | molded.

It is a schematic diagram which shows the structure of the fiber reinforced composite material shaping | molding apparatus 10 which is embodiment in this invention. It is a schematic diagram which shows the structure of the resin impregnation apparatus 22 which is embodiment in this invention. It is a schematic diagram which shows the resin impregnation state of the fiber which is embodiment in this invention.
