Description

 Description Apparatus for producing fiber-reinforced resin molded article and method for producing the same

 The present invention relates to an apparatus for producing a fiber-reinforced resin molded article such as a fiber-reinforced resin pipe, and a method for producing the same. Background art

 Conventionally, fiber-reinforced resin pipes, which are one of the fiber-reinforced resin moldings, are lighter in weight than metal pipes and concrete pipes, and have excellent workability, and are therefore widely used.

 Such a fiber-reinforced resin pipe is formed by continuously winding a plurality of circumferential reinforcing fibers for a circumferentially rotating core while moving in the axial direction while simultaneously winding a plurality of the reinforcing fibers. A regular meandering is performed between the circumferential direction reinforcing fiber reinforcing material wound between the upper side and the circumferential direction reinforcing fiber reinforcing material between the circumferential direction reinforcing fiber reinforcing material. It has been manufactured by continuously supplying in a shape, impregnating these long fiber reinforcing materials with a polymerizable resin composition, and thermally curing the polymerizable resin composition (see, for example, Japanese Patent Application Laid-Open No. Reference is made to Japanese Patent Application Publication No. However, the fiber reinforced resin pipe described above shows that the resin ratio of the layer of the axial reinforcing long fiber reinforcement is compared with the layer of the long reinforcing fiber reinforcement for circumferential reinforcement and the layer of the long fiber reinforcing material for axial reinforcement. Is high, and the long-fiber reinforcing material for axial reinforcement is supplied in a meandering manner, and at the inflection point, is substantially parallel to the long-fiber reinforcing material for circumferential reinforcement. Since the reinforcing fibers are concentrated, the length of the reinforcing fiber between the circumferential reinforcing fiber layer and the reinforcing fiber layer for the axial strengthening is particularly increased during the rapid polymerization reaction. There was a risk of cracks being concentrated at the inflection points of the fiber reinforcement.

Due to these problems, chopped strands are used instead of long fiber reinforcing materials for axial reinforcement. It is currently employed to manufacture fiber reinforced resin pipes using metal. Specifically, the long fiber reinforcing material for circumferential reinforcement, impregnated with the polymerizable resin composition on a core or in an impregnation tank, is wound around the core, and the chopped strands are placed on the core as necessary. To form a fiber-reinforced resin pipe by shaping the polymerizable resin composition with a heater or the like after shaping, and as a result, the chopped strands are almost randomly formed. It is possible to prevent cracks due to distribution and concentration in the fiber direction.

 By the way, there are the following problems in producing the fiber-reinforced dagger pipe in this way.

 First, since the polymerizable resin composition is polymerized by a low-temperature reaction-type polymerization initiator that starts a reaction at room temperature or lower, it takes a long time to complete the polymerization, and the productivity is low.

 Secondly, the force of receiving excess polymerizable resin composition in a container provided below, such as a core mold, so that the polymerizable resin composition can be reused. Since a temperature-reaction type polymerization initiator is incorporated, curing proceeds even when left at room temperature, and it cannot be sufficiently reused. Further, since chopped strands are mixed in the recovered polymerizable resin composition, it is necessary to remove the chopped strands, and the working efficiency is poor.

 Thirdly, just before the chopped strand is sprinkled, the glass fiber roving is cut with a hopper to obtain a chopped strand, so that the chopped strand scatters into the workplace during cutting and sprinkling, The working environment may deteriorate. Therefore, large-scale exhaust equipment is required, which increases equipment costs.

Fourth, the work of replacing the blade of the chopper must be performed, and the work is complicated. The present invention has been made in view of such a problem, and completes the polymerization reaction in a short time without using a chopped strand to prevent cracks! /, Fiber reinforced resin molding It is an object of the present invention to provide an apparatus for manufacturing a fiber-reinforced resin molded body for easily manufacturing a body, and a method for manufacturing the same. Disclosure of the invention

 In order to achieve the above object, an apparatus for manufacturing a fiber-reinforced resin molded product according to the present invention includes a molding die that is supported by a rotating shaft, a molding section provided with a light irradiation device, and a plurality of reinforcing members. A reinforced polyester fiber composition containing a photopolymerization initiator and a reinforcing fiber accumulating portion that arranges a reinforcing fiber group drawn out from each reinforcing fiber roll body on the downstream side in which a fiber bundle is arranged are stored. With an impregnating tank for impregnating the polymerizable resin composition into one of the reinforcing fiber groups and rotating the impregnating fibers of the other reinforcing fiber group by impregnating the polymerizable resin composition. And a reinforcing fiber supply unit provided with a filament winding supply device for supplying a meandering land and a meandering fiber group on one of the strong fiber groups to be wound into a mold, respectively, and impregnated with the polymerizable resin composition. Other reinforcing fiber The reinforcing fiber group in a state where the other reinforcing fiber group meandering at random on the group is laminated is wound up by a rotating molding die, and the reinforcing fiber group wound up by the molding die is irradiated via a light irradiation device. It is characterized in that the polymerizable resin composition is cured by irradiation with light.

According to the present invention, one-half of the reinforcing fibers of each of the plugs arranged in the reinforcing fiber accumulating portion are impregnated with the polymerizable resin composition through an impregnation device and pulled out as one of the reinforcing fiber groups, It is wound on a rotating mold. Further, the other half of the reinforcing fiber is drawn out to the filament winding supply device as the other reinforcing fiber group, and is fed out by the filament-inding supply device. Also, if the other reinforcing fiber group is supplied toward one reinforcing fiber group that is wound into a molding die, the other reinforcing fiber group is placed on one reinforcing fiber group while meandering at random. At the same time, it is adhered to one of the force-absorbing fibers impregnated with the polymerizable resin composition, and is maintained in a meandering state at random. Therefore, the rotating molding die has a reinforcing fiber in a state in which one reinforcing fiber group impregnated with a random resin composition is impregnated on the other reinforcing fiber group impregnated with the resin composition. The fibers are wound up. When the reinforcing fiber group is wound up to a certain thickness in the molding die in this way, impregnation of the polymerizable resin composition of one of the reinforcing fiber groups by the impregnating device is stopped, and filament winding is supplied. After stopping the apparatus and further stopping the rotation of the mold, one of the reinforcing fiber groups and the other reinforcing fiber group are cut. Next, when the mold is rotated and light is irradiated through a light irradiation device, a photopolymerization initiator is blended with the polymerizable resin composition impregnated in the reinforcing fiber group laminated on the mold. Therefore, it starts curing by receiving light. Then, by irradiating light for a certain period of time, if the polymerizable resin composition is hardened to produce a fiber-reinforced resin pipe, the light irradiation is stopped, and the rotation of the mold is stopped. Take out the manufactured fiber reinforced resin pipe.

 As a result, in the manufactured fiber-reinforced resin molded body, one reinforcing fiber group is laminated in the circumferential direction, and the other randomly meandering reinforcing fiber group is laminated in the axial direction. A portion where the reinforcing fibers of the reinforcing fiber group and the reinforcing fibers of the other reinforcing fiber group concentrate does not occur, and the generation of cracks can be reliably prevented.

 In addition, by incorporating a photopolymerization initiator into the polymerizable resin composition, curing can be started promptly by irradiating light, so that fiber-reinforced resin pipes can be manufactured in a short time. And work efficiency can be improved. Further, since curing does not start unless light is irradiated, excess polymerizable resin composition can be recovered and reused.

 In the above configuration, the impregnating device may be provided with a comb-shaped guide member located downstream of the one reinforcing fiber group in the winding direction.

In this case, each of the reinforcing fibers in one of the reinforcing fiber groups impregnated with the polymerizable resin composition passes between the teeth of the comb-shaped guide member, thereby maintaining the interval between the reinforcing fibers and downstream. Can be guided to the side. For this reason, the reinforcing fibers of one reinforcing fiber group adhere to each other in a bundle by the polymerizable resin composition to form a void, and the other reinforcing fiber group supplied on one reinforcing fiber group becomes Dropping from the gap can be reliably prevented. In the above configuration, the length per unit time of the other forcing fiber group supplied from the filament winding supply device is larger than the length per unit time of the forcing fiber group wound on the forming die. Is also good.

 In this case, when the other reinforcing fiber group is supplied onto the one reinforcing fiber group wound on the forming die, each reinforcing fiber in the other reinforcing fiber group is placed on one reinforcing fiber group by an amount corresponding to a higher speed. And it is placed while meandering randomly in the front, rear, left and right directions. Since the polymerizable resin composition is impregnated in one of the reinforcing fiber groups, each reinforcing fiber of the other reinforcing fiber group is adhered to the one of the reinforcing fiber groups and held in a randomly meandering state. Is done.

 In the above configuration, the filament winding supply device may be provided with a guide plate that is located downstream of the other reinforcing fiber group in the supply direction and that controls the protrusion of the other reinforcing fiber group in the width direction.

 In this case, it is possible to restrict the other reinforcing fiber group from deviating beyond the width of the one reinforcing fiber group impregnated with the polymerizable resin composition and wound on the molding die. Each reinforcing fiber of the other reinforcing fiber group can be reliably placed on the group without falling off.

 In the above configuration, the forming unit may be provided with a catching light irradiation device capable of irradiating the outer peripheral surface of the forming die with light.

In this case, one of the reinforcing fiber groups impregnated with the polymerizable resin composition is wound into a molding die in a portion where the reinforcing fibers are stacked thicker at a later time and light hardly transmits and hardly hardens. When lamination is completed, it is possible to irradiate light to hardly hard portions. Also, when the fiber reinforced resin pipe has a different cross section as shown in FIG. 12 (when the thickness changes in the axial direction), it is particularly effective because light can be transmitted intensively. . For this reason, the polymerizable resin composition can be cured at the stage of starting to wind up one of the reinforcing fiber groups, thereby preventing the production of a fiber-reinforced resin pipe without hardening the hard-to-harden portions. can do. In this case, the assisting light irradiating device preferably includes ultraviolet rays but is rich in visible light from the viewpoint of safety.

 In the above configuration, the mold may be opened and closed.

 In this case, closing the mold is preferable because the manufactured fiber-reinforced resin pipe can be easily taken out of the molding die.

That is, since it is not necessary to forcibly pull out the mold, it is possible to remove the mold without damaging the obtained fiber-reinforced resin pipe.

 In the above configuration, the light irradiation device may be capable of moving forward and backward between the irradiation position facing the outer peripheral surface of the mold and the retracted position.

 In the above configuration, the reinforcing fiber supply unit may be capable of reciprocating between a working position approaching the mold and a separated retreat position.

 In this case, the reinforcing fiber supply unit is advanced, and the reinforcing fiber group can be wound around the rotating mold and laminated with a certain thickness, while the reinforcing fiber group laminated with a certain thickness on the mold is irradiated with light. When the impregnated polymerizable resin composition is cured, the reinforcing fiber supply section can be retracted so as not to interfere with the light irradiation device. In addition, it is possible to determine the working position of the reinforcing fiber supply section for fiber reinforced resin pipes having different diameters, and it is possible to manufacture fiber reinforced resin pipes of various diameters with one manufacturing apparatus. it can.

In this case, the excessively impregnated polymerizable resin composition is extruded together with the polymerizable resin composition to be dropped, and the excess polymerizable resin thread to be dropped can be collected in a tray. That is, since the polymerizable resin composition has not been irradiated with light yet, curing has not been started and the polymerizable resin composition can be reused. Therefore, the pot life of the polymerizable resin composition is prolonged. Further, since the filter is provided on the tray, it is possible to prevent dust and the like from being mixed.

The reinforcing fibers F respectively drawn out from the rolls R are aligned and divided into two by a guide 41, and one half of the reinforcing fibers F is sent to the impregnating device 6 of the reinforcing fiber supply unit 1C described later and the other half. The sections are respectively guided by filament winding supply devices 7.

 Here, the group of the reinforcing fibers guided to the impregnating device 6 is referred to as one of the reinforcing fibers, and the symbol FA is used, and the group of the reinforcing fibers guided to the filament winding supply device 7 is The symbol FC is used as the other reinforcing fiber group.

 In addition, the mouth R of the plurality of reinforcing fibers F guided to the impregnating device 6 of the reinforcing fiber supply unit 1C and the roll R of the reinforcing fibers F guided to the filament winding supply device 7 are individually adapted to each device. And supply it to each device. '' The reinforcing fiber supply section 1C includes a supply frame 5 movable in the front-rear direction (the left-right direction in FIG. 1), an impregnation device 6 provided on the supply frame 5, a filament winding supply device 7, And a pressing roller device 8.

As shown in FIGS. 6 and 7, the supply frame 5 is composed of a pair of guide rails 51 laid in the front-rear direction and a frame book slidably mounted on the guide rails 51. Body 52, an electric motor 53 provided on the frame body 52, a chain wheel 54 provided on the output shaft thereof, and a rotating shaft 55 rotatably supported by the frame body 52. A chain wheel 56 and a pinion 57 fixed to the rotating shaft 55 and a rack 58 laid between the pair of guide rails 51 are provided between the chain wheels 54 and 56. A chain 59 is wound endlessly, and a pinion 57 is combined with a rack 58.

 Therefore, by rotating the electric motor 53, the rotating shaft 55 is rotated at the reduction ratio set via the chain wheels 54, 56 and the chain 59, and at the same time, the rack 58 is rotated. The pinion 5 7 that engages is rotated. Therefore, the frame body 52 can be moved in the front-rear direction along the guide rail 51 with respect to the rack 58. The reinforcing body F of the other reinforcing fiber group FC drawn from the reinforcing fiber accumulating portion 1B is changed in direction to the filament winding supply device 7 by changing the direction. For guiding, a guide 59 is provided in which a number of holes are formed to allow each reinforcing fiber F to pass through.

 Further, the frame main body 52 of the supply frame 5 has a gutter 50 (see FIG. 1) extending below the reinforcing fiber group FA toward the downstream side. Therefore, the polymerizable resin composition 6A dropped from one of the reinforcing fiber groups FA impregnated with the polymerizable resin composition 6A can be collected and led to the toy 9. In this case, the length of the gutter 0 is set according to the advance / retreat distance of the supply frame 5.

As shown in detail in FIG. 8, the impregnating device 6 is fixed to the frame main body 5 2 of the supply frame 5 and has an impregnating tank 61 for storing a polymerizable resin composition 6 A containing a photopolymerization initiator. , A pair of guide rollers 62 provided above the front and rear ends of the impregnation tank 61, a lifting cylinder 63 fixed to the frame body 52 (see Fig. 1), and a lifting cylinder 63 A force bar 64 fixed to the piston rod and movable up and down by a guide (not shown), a pair of impregnated rollers 65 suspended from the force par 64, and a lifting cylinder 63 By performing the extension operation, the pair of impregnating rollers 65 is lowered through the cover 64 between the pair of left and right guide rollers 62, and the pair of left and right guide rollers One of the strong fiber groups FA passing between the rollers 62 can be immersed in the polymerizable luster composition 6A stored in the impregnation tank 61. (

 Further, the impregnation tank 61 is provided with a comb-shaped guide member 66 located on the downstream side of the front guide roller 62. The guide member 66 is impregnated with the polymerizable resin composition 6A, and each reinforcing fiber F of one of the reinforcing fiber groups FA guided forward adheres through the polymerizable resin composition 6A, The formation of a bundle prevents the formation of voids in one of the reinforcing fiber groups FA. That is, as described later, when the other reinforcing fiber group FC is supplied onto one reinforcing fiber group FA, each trapping of the other reinforcing fiber group FC is performed through a gap formed in one reinforcing fiber group FA. Prevents strong fiber F from falling to the ground.

 In addition, it is located on the upstream side of the rear guide roller 62, and changes the direction of each reinforcing fiber F of one of the reinforcing fiber groups FA drawn out from the above-described reinforcing fiber accumulating portion 1B. In order to guide the reinforcing fibers F horizontally, a guide 67 having a number of holes through which the reinforcing fibers F pass is provided.

As shown in FIG. 9 and FIG. 10, the filament winding supply device 7 includes a pair of guide rails 7 1 extending vertically in the frame main body 52 of the supply frame 5 at intervals in the left-right direction. A lifting frame 72 slidably mounted on the guide rail 71, and a screw rotatably supported by the frame body 52 and having a handle 731 screwed to the lifting frame 72 The shaft '73, the supply roller 74 rotatably supported by the lifting frame 72, and the catch rotatably supported by the lifting frame 72 in contact with the outer peripheral surface of the supply roller 74. Auxiliary roller 7 41, electric motor 75 provided on lifting frame 72, chain wheel 76 provided on output shaft of electric motor 75, and provided on rotating shaft of supply roller 74 And a chain 778 wound endlessly between the chainwheels 7.6 and 77, By rotating the driving motor 75, the supply roller 74 is rotated at a set reduction ratio via the chain wheels 76, 77 and the chain 78, and at the same time, the auxiliary roller 7 in contact with the supply roller 74. 4 1 can be rotated in the opposite direction. At this time, make sure to pass between the supply roller 74 and the auxiliary roller 74. The other group of reinforcing fibers FC guided by this can be supplied toward the front. Here, the rotation speed of the supply roller 74, that is, the supply length of the other reinforcing fiber group FC per unit time is determined by the peripheral speed of the molding die 2, that is, the one reinforcing fiber per unit time. It is set slightly larger than the winding length of group FA. For this reason, as described later, when the other reinforcing fiber group FC is supplied onto one of the reinforcing fiber groups FC which is drawn and wound on the molding die 2, each reinforcing fiber in the other reinforcing fiber group FC is supplied. The fiber F is slackened on one of the forcing fiber groups FA by an amount corresponding to the higher speed, and is placed on one of the forcing fiber groups FA while meandering randomly in the front-rear and left-right directions (No. 11). See figure). '

 In this case, by rotating the handle 7 31, the screw shaft 7 3 rotates, and the elevating frame 7 2 screwed to the screw shaft 7 3 can be moved up and down along the guide rail 7 1 . In other words, the supply height position of the other reinforcing fiber group FC can be adjusted according to the height at which one reinforcing fiber group FA wound on the molding die 2 passes.

 In addition, a pair of guide plates 79 are mounted on the lifting frame 72 in front of the support frame 72 so as to be rotatable around the support pad 72. The guide plate 79 regulates the other reinforcing fiber group FC supplied through the filament winding supply device 7 so as not to deviate beyond the width of the one reinforcing fiber group FA.

 In the supply frame 5, the reinforcing fibers F of the other reinforcing fiber group FC drawn out from the reinforcing fiber accumulating portion 1B and passing through the guide 59 provided in the supply frame 5 are changed in direction. A guide 70 having a large number of holes through which each reinforcing fiber F is inserted is provided to guide the reinforcing fiber F substantially horizontally to the supply roller 74.

As shown in FIGS. 1 and 2, the pressing roller device 8 includes a guide rail / layer 81 extending vertically in the frame main body 52 of the supply frame 5 with a horizontal space therebetween, and a guide rail rail. 8 1 An elevating frame 8 2 slidably mounted on 1, an arm 8 3 rotatably supported on the elevating frame 8 2 around a horizontal axis, an arm 8 3 and an elevating frame 8 2, a pressing cylinder 84, a pressing roller 85 rotatably supported at the tip of an arm 83, an electric motor 86 provided on a lifting frame 82, and an electric motor 86. And a screw shaft 8 7 screwed to the lifting frame 82 and connected to the output shaft of the molding die 2. It is possible to swing between the contacting pressing position and the retracted position separated from the outer peripheral surface. In addition, by rotating the electric motor 86, the screw shaft 87 rotates, and the lifting frame 82 with the screw 87 is screwed can be moved up and down along the guide rail 81. The pressing roller 85 can be adjusted so as to be in contact with the outer peripheral surface of the molding die 2 according to the size of the molding die 2.

 Next, a manufacturing process of the fiber reinforced resin pipe 10 configured as described above will be described below with reference to the drawings.

 First, as shown in FIG. 4, the mold 2 is closed. Next, after removing the flange member 25 from the fixed mold 22 using a simple crane or the like, a rubber ring 1 1 is attached to the circumferential groove 2 2a of the fixed mold 2 2 of the closed mold 2. Installing. Then, the flange member 25 is attached to the fixed mold 25 again. At this time, the protrusion 25 a of the flange member 25 is fitted into the recess 22 b of the fixed mold 22, and the flange member 25 is positioned with respect to the fixed mold 22.

 When the flange member 25 is attached, the mold 2 is opened as shown in FIG. At this time, the concave portions of the swing molds 23 and the concave portions of the elevating molds 24 are fitted into the convex portions 25a of the flange members 25, respectively, so as to be positioned. Further, each rubber ring 11 is attached to each circumferential groove of each swing mold 23 and each circumferential groove of the elevating mold 24.

On the other hand, the forcing fiber F of each vitreous body arranged in the forcing fiber accumulating portion 1 B: is passed through each hole of the guide 4 ′ 1, is aligned and bisected, and then is cut into one half. Is passed through each hole of the guide 67 of the impregnating device 6 as one reinforcing fiber group FA, and then passed between them so as to be sandwiched between a pair of front and rear guide rollers 62. , And The guide member 66 is drawn out to the downstream side of the impregnation tank 61 through each tooth.

 The other half is passed through each hole of guides 59 and 59 provided on the frame body 52 as the other group of the reinforcing fibers FC, and then the guide 7 of the filament winding supply device 7 is used. It is inserted into each hole of No. 0 and is inserted between them so as to be sandwiched between the supply roller 74 and the auxiliary roller 741, and is pulled out downstream thereof.

 Thereafter, the electric motor 53 of the supply frame 5 is driven, and the pinion 57 that engages with the rack 58 via the chain wheels 54, 56 and the chain 59 is rotated to rotate the frame body.

5 Advance 2 to the working position.

 Next, one of the reinforcing fiber groups FA drawn out to the impregnating device 6 is not shown, but after being bound to a jig, the jig is locked to the forming die 2 and the forming die 2 is slightly rotated, so that one of the collecting fibers The strong fiber group FA is wound around the outer peripheral surface of the mold 2 approximately one round. At this time, the polymerizable resin composition is applied to one of the force-absorbing fiber groups FA wound around the outer peripheral surface of the force forming mold 2 (not shown in detail).

6 A is applied and adhered to the mold 2. In addition, the handle 731 is rotated to raise and lower the lifting frame 72, and adjust the height of the supply roller 74 and the auxiliary roller 741. At the same time, the electric motor 86 of the pressing roller device 8 is driven, and the height is adjusted so that the pressing roller 85 contacts the outer peripheral surface of the molding die 2.

 Further, the auxiliary light irradiation device 36 is rotated to the irradiation position so as to face the outer peripheral surface of the mold 2. Also, the lifting cylinder 63 of the impregnating device 6 is extended, the pressing roller 65 enters the inside of the impregnating tank 61, and one reinforcing fiber drawn out between the pair of front and rear guide rollers 62. The group FA is immersed in the polymerizable resin composition 6A in the impregnation tank 61. '

Thereafter, when the jig (not shown) is removed from the molding die 2 and the molding die 2 is rotated, one of the reinforcing fiber groups FA adhered to the outer peripheral surface of the molding die 2 is wound around the outer peripheral surface of the molding die 2. Will be taken away. At this time, one of the reinforcing fiber groups FA passes through the polymerizable resin composition 6A stored in the impregnation tank 61, so that the polymerizable resin composition 6A is impregnated and wound around the molding die 2. Will be taken away. Here, if the lamp 3 61 of the auxiliary light irradiation device 36 is turned on, the rubber ring W

 twenty two

 11 A portion formed by the outer end surface of 1, the outer peripheral surface of the mold 2 and the inner end surfaces of the flange members 21 and 25 is irradiated with light, and one of the reinforcements laminated on the A portion The polymerizable resin composition 6A impregnated in the fiber group FA is light-cured.

 That is, the polymerizable resin composition 6A impregnated in one of the reinforcing fiber groups FA wound around the part A has a thicker product thickness in the relevant part, so that one of the reinforcing fiber groups FA is laminated later. Light is less likely to pass through, and it is difficult to harden. Therefore, by fiber-curing the polymerizable resin composition 6A at the stage of starting the winding of one of the reinforcing fiber groups FA, the fiber-reinforced resin pipe 10 is manufactured with the part A uncured. Can be prevented. ''

 In this case, although the lamp 36 1 of the assisting light irradiating device 36 contains ultraviolet rays, it has visible light, so there is no problem in safety.

 As described above, by the rotation of the molding die 2, the polymerizable resin composition 6A impregnated in the one reinforcing fiber group FA laminated on the portion A of the molding die 2 is subjected to light curing by the auxiliary light irradiation device 36. Meanwhile, one of the reinforcing fiber groups FA impregnated with the polymerizable resin composition 6 A is wound up into the mold 2.

 In this state, one of the reinforcing fiber groups FA is wound around the molding die 2 for a certain period of time, and once the rubber ring 11 protruding from the outer peripheral surface of the molding die 2 is laminated by the height and almost the thickness, once the molding die 2 Is stopped, and the auxiliary light irradiation device 36 is stored at the retracted position. Then, by simultaneously rotating the molding die 2 again and simultaneously driving the electric motor 75 of the filament winding / feeding device 7, the supply roller # 4 and the auxiliary roller 741 are rotated, and the other capture force is applied. Feed out fiber group FC.

Here, the rotation speed of the supply roller 74, that is, the supply length of the other reinforcing fiber group FC per unit time is determined by the peripheral speed of the molding die 2, that is, the one reinforcing fiber group FA per unit time. Since the length is set slightly larger than the winding length, when the other reinforcing fiber group FC is supplied onto one reinforcing fiber group FA wound on the molding die 2, the other reinforcing fiber group FC is supplied. Of each reinforcing fiber F It will be slack on the fiber group FA and, as shown in Fig. 11, it will be placed while meandering randomly in the front, rear, left and right directions.

 At this time, the reinforcing fibers F of one of the reinforcing fiber groups FA pass between the teeth of the guide member 66 and are maintained at an interval from each other, and are adhered in a bundle by the polymerizable resin composition 6A. This ensures that voids are not created. For this reason, one reinforcing fiber group F A in which each reinforcing fiber F moves at a substantially constant interval, and each of the reinforcing fiber groups F C in the other reinforcing fiber group F C is reliably disposed. ,

 Also, even if each of the reinforcing fibers F of the other reinforcing fiber group FC attempts to deviate beyond the width of one of the reinforcing fiber groups FA, since it is regulated by the pair of left and right guide plates 79, one of the reinforcing fibers F is surely removed. Located on the strong fiber group FA. In addition, since one of the reinforcing fiber groups FA is impregnated with the polymerizable resin composition 6A, each of the reinforcing fibers F of the other reinforcing fiber group FC is randomly adhered to the one of the reinforcing fiber groups FA. It is kept in a meandering state.

 As a result, the rotating mold 2 has a state in which the other reinforcing fiber group FC, which is randomly meandered and adhered, is laminated on one reinforcing fiber group FA impregnated with the polymerizable resin composition 6A. Is wound up. That is, in the circumferential direction of the outer peripheral surface of the molding die 2, the negative reinforcing fiber group FA is laminated, and in the axial direction, the other reinforcing fiber group FC meandering at random is laminated, and one reinforcing fiber group FC is laminated. The reinforcing fiber group is wound around the mold 2 without generating a location where the reinforcing fiber F of the group FA and the reinforcing fiber F of the other reinforcing fiber group FC concentrate.

A reinforcing fiber group in a state where the other reinforcing fiber group FC meandering and sticking in a random manner on one of the reinforcing fiber groups FA in which the mold 2 is impregnated with the polymerizable resin composition 6 A is wound. When it is removed and reaches a certain thickness, the elevating cylinder 63 is contracted to raise the impregnation roller 65 from the polymerizable resin composition 6A, and the electric motor 75 of the filament winding supply device 7 Stop driving. Further, if a certain length is wound in this state, after the rotation of the molding die 2 is stopped, one of the reinforcing fiber groups FA and the other reinforcing fiber group FC are fed to the downstream side of the filament winding supply device 7. Off Then, the supply frame 5 is retracted to the reinforcing fiber accumulation section 1B side.

 Thereafter, the molding die 2 was rotated again, and although not shown in detail, a roller was pressed against the laminated reinforcing fiber group to discharge air mixed in the laminated reinforcing fiber group, and excessively impregnated. Extrude 6 A of the polymerizable resin composition. Extruded excess polymerizable resin composition 6A is dropped from tray 2 onto tray 9 and collected through filter 91 together with polymer resin composition 6A dropped during rotation of mold 2. After being collected in the mass 92, it is collected in the regeneration impregnation tank 71 by the collection pump 93. That is, since the polymerizable resin composition 6A has not been irradiated with light yet, curing has not been started and the polymerizable resin composition 6A can be reused. Therefore, the pot life of the polymerizable resin composition 6A is prolonged.

 At this time, dust and the like are prevented from being mixed in by the filter 91 provided on the tray 9. This is particularly effective when the fiber reinforced resin pipes have different cross sections. That is, when forming a pipe having the above-described shape, it is preferable to use a light irradiation auxiliary lamp, and irradiation during the winding of the auxiliary lamp is likely to cause excess resin gelling. . It is possible to prevent that the gelly dangling material falls into the tray 9 together with the dripped resin and is collected in the impregnation tank 71 to cause clogging and the like, and also prevented from being mixed into the collected resin. Can be. In this case, the size of the mesh of the filter 91 is desirably selected between 3 and 4 Omm. When the defoaming operation is completed, the electric motor (not shown) of the light irradiation device 3 is driven to move the driving frame 32, that is, the lamp shade 33, to the irradiation position facing the upper outer peripheral surface of the molding die 2, and Adjust the distance to the outer peripheral surface of the mold 2. Then, after a light-shielding curtain (not shown) is stretched around the manufacturing apparatus 1, the mold 2 is rotated and the light of the UV lamp 34 is irradiated.

At this time, since the photopolymerization initiator is mixed in the polymerizable resin composition 6 A impregnated in the reinforcing fiber group laminated on the molding die 2, the light from the ultraviolet lamp 34 from the UV lamp 34 is irradiated. Receiving starts curing. Then, if the polymerizable resin composition 6A is hardened by irradiating the light of the UV lamp 34 for a certain period of time, that is, the fiber-reinforced resin pipe 1 When 0 is manufactured, the irradiation of the light from the UV lamps 34 is stopped, and the mold is moved to the retracted position and the rotation of the mold 2 is stopped. At the same time, return the blackout curtain to its original position.

 Next, contrary to the above, after closing the mold 2, the flange member 25 is released from the fixed mold 22. Then, a band or the like is wrapped around the manufactured fiber-reinforced resin pipe 10, lifted by an overhead crane or the like, and moved to the next step. In the fiber reinforced resin pipe 10 manufactured in this manner, one reinforcing fiber group FA is laminated in the circumferential direction, and the other reinforcing fiber group FC meandering randomly in the axial direction. As a result, there is no place where the reinforcing fiber F of one reinforcing fiber group FA and the reinforcing fiber F of the other reinforcing fiber group FC concentrate, and the generation of cracks can be securely stopped by the P force. it can.

 In addition, since the photopolymerization initiator is blended with the polymerizable resin composition 6A, curing can be started promptly by irradiating light, so that the fiber reinforced resin pipe 10 can be manufactured in a short time. Work efficiency can be improved. In addition, since the hard coating is not started unless light is irradiated, the excess polymerizable resin composition 6A can be recovered and reused.

 In the above-described embodiment, the case where one reinforcing fiber group FA is directly wound on the molding die 2 has been described. However, in consideration of the releasability from the outer peripheral surface of the molding die 2, the fiber-reinforced resin It is preferable to start the operation after winding a release film around the outer peripheral surface of the mold 2 before manufacturing the pipe 10. ,

 Next, an apparatus 1 for manufacturing the fiber-reinforced resin pipe 10 according to the first embodiment, an apparatus for manufacturing another fiber-reinforced resin pipe different from the method for manufacturing the same, and a method for manufacturing the same will be described. Note that the same reference numerals are given to constituent members having the same names as the constituent members of the manufacturing apparatus 1 of the fiber-reinforced resin pipe 10 according to the first embodiment.

Embodiment 2>

Next, one embodiment of the manufacturing apparatus 1 for the fiber-reinforced resin pipe 10 according to the second embodiment The state will be described with reference to FIGS. 13 and 14. '

 As shown in FIG. 13, the manufacturing apparatus 1 includes a forming section 1A, a reinforcing fiber collecting section 1B provided separately from the forming section 1A, a forming section 1A and the reinforcing fiber collecting section 1A. And a reinforcing fiber supply unit 1C, which is provided between the two.

 The molding part 1A is a core-shaped molding die 2 having a drum shape rotatably supported on a shaft and a polymerizable resin composition 6A attached to a reinforcing fiber F described below. It comprises a light irradiation device 3 for irradiating light having a wavelength at which the polymerization initiator starts a reaction, and a nozzle 10 for spraying or dropping the polymerizable resin composition 6A, and the reinforcing fiber F is formed into a molding die 2. Is wound around the outer peripheral surface a predetermined number of times and shaped into a pipe.

 As shown in FIG. 14, the light irradiation device 3 is provided with a shutter 37, and by opening and closing the shutter 37, the light of the lamp 34 is reinforced by the reinforcing fiber F wound around the mold 2. Irradiated toward. The light irradiation device 3 includes an air supply pipe 38 1 and an exhaust pipe 38 2 connected to a blower (not shown), and a heat ray filter 39 for controlling the amount of light emitted from the lamp 34. Is provided.

 In addition, a tray 9 for collecting the polymerizable resin composition (polymerizable resin composition 6A containing a photopolymerization initiator) is provided in the molding portion 1A so as to face the lower outer peripheral surface of the molding die 2. The polymerizable resin composition 6A collected in the tray 9 is collected in an impregnation tank 61 of an impregnation device (not shown) described later via a collection pump 93.

The reinforcing fiber accumulating portion 1B is configured by arranging a plurality of jaws R of reinforcing fibers F such as glass roving. The reinforcing fibers F drawn out from the respective rolls R are divided into two in a aligned state, and one half of the reinforcing fibers F is impregnated with the impregnating device (impregnating tank 6 1 in FIG. The other half is guided to a filament winding supply device (not shown, see supply roller 74 in FIG. 13) of reinforcing fiber supply section 1C. The reinforcing fiber group guided to the impregnating device is referred to as one reinforcing fiber group and the symbol FA is used, and the reinforcing fiber group guided to the filament winding supply device is used as the other reinforcing fiber group. And use the code FC (See Figure 13).

 In addition, the mullet R of the plurality of reinforcing fibers F guided to the impregnating device of the reinforcing fiber supply unit 1C and the mullet R of the reinforcing fiber F guided to the filament winding supply device are matched to each device. You may arrange | position individually and supply it to each apparatus. ,

 Reinforcing fiber supply section 1.C is provided with an impregnating device for storing polymerizable resin composition 6A containing a photopolymerization initiator, and feed of the other reinforcing fiber group FC drawn from reinforcing fiber accumulating section 1B. And a filament winding supply device for changing the feeding direction. The other reinforcing fiber group FC sent out from the filament winding supply device is adhered. The adhesion of the other reinforcing fiber group F C prevents the reinforcing fiber group F from becoming a bundle, thereby preventing a void from being generated in the one reinforcing fiber group F A. That is, as described later, when the other reinforcing fiber group FC is supplied onto the one reinforcing fiber group FA, each reinforcing fiber F of the other reinforcing fiber group FC passes through the void formed in the one reinforcing fiber group FA. To prevent it from falling to the ground.

The filament winding supply device is provided with a supply roller 74 for feeding out the other reinforcing fiber group FC, and the feeding speed for sending out the other reinforcing fiber group FC by the supply roller 74 is a drum-shaped forming die. The rotation speed is set faster than 2. That is, the supply length of the other reinforcing fiber group FC per unit time of the filament winding supply device 7 is set to be slightly larger than the winding length of one reinforcing fiber group FA per unit time of the mold 2. Have been. For this reason, when the other reinforcing fiber group FC is supplied onto one reinforcing fiber group FA that is aligned and wound into the molding die 2, each force «UF F in the other reinforcing fiber group FC is The higher the speed, the more slack it is on one of the reinforcing fiber groups FA, and it is placed on one of the reinforcing fiber groups FA while meandering randomly in the front-rear and left-right directions (see Fig. 11). That is, the other reinforcing fiber group FC sent by the supply roller 74 is sent out faster than the rotation speed of the molding die 2, and thus has an irregular loop or meandering due to its winding habit and feed pool. In this state, it is continuously supplied onto one of the reinforcing fiber groups FA between the impregnation tank 61 and the forming die 2 and continuously with the one reinforcing fiber group FA until the thickness of the forming die 2 reaches a predetermined value. It is wound around.

 Next, a manufacturing process of the fiber reinforced resin pipe 10 configured as described above will be described below with reference to FIG.

 In this manufacturing method, one reinforcing fiber group FA as a circumferential long fiber reinforcing material drawn out from the reinforcing fiber supply section 1C and aligned in parallel is used as a polymer resin containing a photopolymerization initiator. After continuously passing through the impregnation tank 6 1 in which the composition 6 A is stored and impregnating one of the reinforcing fiber groups FA with the polymerizable resin composition 6 A, it is wound around the rotating mold 2 a predetermined number of times. .

 Then, the other reinforcing fiber group FC as an axial long fiber reinforcing material drawn out from the reinforcing fiber supply unit 1C and sent by the supply roller 74 is sent out faster than the rotation speed of the molding die 2. As a result, the fibers are continuously supplied between the impregnation tank 61 and the molding die 2 on one reinforcing fiber group FA in an irregular loop or meandering state due to the curl and feed pool. To the reinforcing fiber group FA. Then, it is continuously wound around one of the reinforcing fiber groups F A to the molding die 2 until it reaches a predetermined thickness.

 Further, the polymerizable resin composition 6A is further sprayed or dropped from the nozzle 10 onto one of the reinforcing fiber groups FA and the other reinforcing fiber group FC wound around the molding die 2 from above the molding die 2, The impregnating roll 101 forms a uniform and pipe shape along the peripheral surface of the mold 2. Thereafter, the light irradiation device 3 is irradiated with light having a wavelength at which the photopolymerization initiator starts a reaction in the direction of the mold 2 to start the photopolymerization reaction.

 Alternatively, simultaneously with the winding around the core mold, the light irradiation device 3 is illuminated in the rear with light having a wavelength at which the photopolymerization initiator starts the reaction in the direction of the molding die 2, and the photopolymerization reaction is started during the shaping. Start.

In addition, after being wound around the mold 2 until a certain thickness is obtained, and then cured by irradiating light, it is wound again until the thickness becomes a certain thickness, and then subjected to light irradiation again to perform multi-stage curing such as stiffening. You may.

 In the case of irradiating the light from the light irradiation device 3 simultaneously with the winding on the molding die 2, a method of irradiating the whole time or partly during the winding can be considered. After the winding and shaping of the partially illuminated table meal, light is again irradiated, and the unirradiated laminate is cured.

 The light irradiation from the light irradiation device 3 selects a wavelength and an irradiation amount at which the compounded photopolymerization initiator reacts most efficiently.

 In the case where a high-temperature reaction type polymerization initiator is blended, the polymerization reaction by the high-temperature reaction type polymerization initiator is started by reaction heat generated by the photopolymerization reaction, and light is irradiated by a reinforcing fiber or the like. The hardening can be advanced to the inside even if the fiber pipe 10 has a small thickness. Even when the thickness is small, the curing speed can be increased by incorporating a high-temperature reaction-type polymerization initiator.

 In addition, when a photopolymerization initiator that reacts in the wavelength region including visible light is included, even if the thickness of the molded product is high, the light is likely to be blocked by a fiber reinforcing material or the like. The curing can be advanced to the inside with visible light. In addition, since the film is slowly cured by visible light during winding, the entire molding speed can be increased.

 When molding thick-walled products, light irradiation is insufficient and cracks may occur due to poor curing.Therefore, after winding to a certain thickness, curing by light irradiation is performed. After that, it is effective to carry out multi-stage hardening for re-winding and stiffening. Although it depends on the entire thickness, the constant thickness is preferably not more than 20 mm, more preferably about 8 to 15 mm, from the viewpoint of prevention of force cracks. Light irradiation may be performed while winding to increase the molding speed or prevent cracking due to poor curing.

In the cross section, slight cracking was observed at about 15 mm from the outer surface.

Example 4>,

 In the fourth embodiment, the fiber-reinforced resin pipe 10 was manufactured in the same manner as in the first embodiment except that the thickness was different from that of the first embodiment. In the fourth embodiment, the thickness of the fiber reinforced tree pipe 10 is set to 3 O mm.

 Next, a fiber reinforced resin pipe 10 having the configuration in Example 4 was manufactured under the following manufacturing conditions. The results will be described below.

First, under the 4-1 production conditions, the reinforcing fibers F were wound around the mold 2 until the total thickness became 30 mm. Thereafter, the wound reinforcing fiber F was cured by irradiating it with 120 wZ cm X 2 lamps. The completion time of the curing by the light irradiation was 60 minutes. Next, under the fourth-second production conditions, while the reinforcing fiber F was wound around the molding die 2, light irradiation was performed with one lamp of 8 OwZ cmX, and winding was performed until the total thickness became 3 Omm. After that, the wound reinforcing fiber F was cured by irradiating light with two lights of 120 wZcmX. The completion time of hardening by this light irradiation was 15 minutes.

Thereafter, the wound captive fiber F was irradiated with light using a 120 w / _C mX2 lamp to be cured. The completion time of the stiffening by this irradiation was 10 minutes.

 Next, under the fourth-fourth production conditions, while the reinforcing fiber F was wound around the molding die 2, light irradiation was performed with a single lamp of 40 wcm x 1 until the total thickness became 3 Omm. Thereafter, the wound reinforcing fiber F was cured by irradiating light with a 120 w / cniX2 lamp. The completion time of curing by this irradiation was 60 minutes.

 In each section of the fiber-reinforced resin pipe 10 manufactured under the respective manufacturing conditions of Example 4, a force crack was generated only in the fiber-reinforced resin pipe 10 relating to the eleventh-first embodiment. As a result, the production apparatus 1 for the fiber-reinforced resin pipe 10 according to the second embodiment and the method for producing the same were as described above. As can be seen from the examples, it has the following excellent effects.

 First, by initiating a polymerization reaction with a photopolymerization initiator, the polymerization reaction speed is increased and productivity is improved. Further, since the polymerization reaction by the high-temperature reaction-type polymerization initiator is started by the heat of the reaction due to the photopolymerization, it is possible to react and harden the portion not exposed to the light. For each layer, curing can be evenly promoted by blending a photopolymerization initiator that reacts in a wavelength region including visible light, continuous light irradiation, and multi-step light irradiation. Therefore, the occurrence of cracks between layers can be suppressed.

Secondly, the reaction does not open rapidly even if left at room temperature unless exposed to light, so that the polymerizable resin composition 6Α that has fallen off during spraying can be reused as it is. Also impregnated The potable life of the polymerizable resin composition 6A in the tank (see the life shown in Table 1) is long, and maintenance work such as cleaning of the impregnation tank and the like can be reduced, and costs can be reduced. Third, since the axially long fiber reinforcing material is not a chopped strand but a continuous fiber, there is no scattering around the fiber, the working environment is good, and the polymerizable resin composition 6A that has spilled out. It is suitable for reuse of resin without clogging the pump 93 and piping because it does not mix. Since there is no scattering of fibers, the reinforcing fibers F do not adhere to the surface of the lamp 34 and do not hinder light irradiation.

 In Embodiment 2, one of the reinforcing fiber groups FA is impregnated with the polymerizable resin composition 6A, and then the other reinforcing fiber group FC is supplied onto the one reinforcing fiber group FA. But not limited to this. For example, one reinforcing fiber group FA is sandwiched between one reinforcing fiber group FA and one reinforcing fiber group FA, and the other reinforcing fiber group FA and the other reinforcing fiber group FC are impregnated in the impregnation tank. At the same time as impregnating tank 61, impregnating polymerizable resin composition 6A into one of the reinforcing fiber groups FA and simultaneously impregnating polymerizable resin composition 6A into the other reinforcing fiber group FC. No problem.

 Further, in the second embodiment, the force of making the other reinforcing fiber group FC into an irregular meandering shape or a loop shape by utilizing the winding habit of the other reinforcing fiber group FC is limited to this. Instead, for example, the trapezoidal mechanism may be used to meander irregularly. In this case, since the shape becomes a meandering shape or a loop shape at random, even if the direction overlaps with one of the reinforcing fiber groups FA, no crack is generated.

Further, in the second embodiment, only the reinforcing fiber F made of glass fiber roving is used to capture the strength of the fiber reinforced resin pipe 10 to be manufactured, but the present invention is not limited to this. In addition to the reinforcing fiber F, if necessary, a nonwoven fabric or the like may be laminated on the inner surface side and outer surface side of the fiber reinforced resin pipe 10 to be produced. , Cross-shaped, or mat-shaped reinforcing materials may be laminated. Further, the cylindrical body made of rubber may be provided coaxially with the cylindrical body of the fiber-reinforced resin pipe 10 manufactured in the second embodiment. It is preferable for improving the degree. Industrial applicability

 ADVANTAGE OF THE INVENTION As mentioned above, according to the manufacturing apparatus of the fiber-reinforced resin molded body and the manufacturing method thereof according to the present invention, the fiber-reinforced resin pipe free of cracks by completing the polymerization reaction in a short time without using chopped strands Can be easily manufactured.
