Description

  The present invention relates to a processing apparatus for processing reinforcing fibers.

  Conventionally, flat fibers that are aligned in one direction by opening and widening a unidirectional fiber bundle formed by bundling each filament constituting a reinforcing fiber such as carbon fiber, glass fiber, and aramid fiber. A strip-shaped fiber bundle in a state is impregnated with a matrix resin such as a thermosetting resin such as epoxy resin or unsaturated polyester resin, or a thermoplastic resin such as polyolefin resin, aliphatic polyamide resin, or polyethylene terephthalate resin. Directional prepreg is provided. In order to form a high-quality unidirectional prepreg, it is necessary to open the unidirectional fiber bundle with high accuracy, and various techniques for opening the unidirectional fiber bundle have been proposed. For example, in Patent Documents 1 and 2, the unidirectional fiber bundle is moved in the width direction by passing the airflow through the unidirectional fiber bundle in a direction intersecting the traveling direction while traveling the unidirectional fiber bundle in the longitudinal direction. A technique for spreading and opening is disclosed.

  Various techniques have been proposed for impregnating a resin into an opened strip-shaped unidirectional fiber bundle. For example, Patent Document 3 discloses a technique in which a unidirectional fiber bundle is impregnated with a resin by pressing a spread strip-shaped unidirectional fiber bundle through a nip roll while the resin film is overlaid. Has been. Further, for example, Patent Document 4 discloses a technique of impregnating a unidirectional fiber bundle with resin by overlapping the opened strip-shaped unidirectional fiber bundle and a resin film and passing them between hot rollers. .

International Publication No. 97/41285 (pages 13 to 14, FIG. 2, abstract, etc.) Japanese Patent Laid-Open No. 11-200136 (paragraph 0025, FIG. 1, abstract, etc.) Japanese Patent Laid-Open No. 2001-288639 (paragraphs 0058 to 0060, FIG. 1, etc.) JP-A-10-292238 (paragraph 0053, etc.)

  In the techniques disclosed in Patent Documents 1 and 2, since the unidirectional fiber bundle is widened and opened by an air flow, a strong tension cannot be applied to the unidirectional fiber bundle when the fiber is opened. Therefore, it has been difficult to stably process the unidirectional fiber bundle at high speed. Further, in the impregnation techniques disclosed in Patent Documents 3 and 4, there is a demand for shortening the processing time for melting the resin and impregnating the unidirectional fiber bundle. Moreover, when impregnating resin to a unidirectional fiber bundle, the technique which improves the joining state of each filament and resin which comprise a reinforced fiber is desired. Furthermore, development of a technique for easily joining each filament constituting the reinforcing fiber and a metal such as Cu, Al, or Fe is also desired.

  This invention is made | formed in view of an above-described subject, and it aims at providing the technique which can process a reinforced fiber stably at high speed.

Between the vibration means for applying ultrasonic vibration in the orthogonal pressing direction, the support surface, and the pressing surface of the pressing body that ultrasonically vibrates in the pressing direction by the vibration means, and the reinforcing member In a state where fibers are overlapped and sandwiched, the reinforcing fiber and the resin member, and a moving means that relatively moves the pressing body, the shielding body has a shielding function that hardly transmits heat from the outside. It is characterized by having.

  According to such a configuration, the pressing surface with the reinforcing fiber and the resin member sandwiched between the supporting surface of the supporting body and the pressing surface of the pressing body that ultrasonically vibrates in the pressing direction orthogonal to the supporting surface. When the reinforcing fiber and the resin member are processed (for example, impregnation treatment) by moving the pressing portion of the reinforcing fiber along the longitudinal direction of the reinforcing fiber, ultrasonic vibration energy is applied to press the supporting surface and the pressing surface. The thermal energy generated in the reinforcing fiber and the resin member sandwiched between the surfaces is prevented from escaping to the pressing body by the shielding function of the pressing body, and the generated thermal energy is sandwiched between the support surface and the pressing surface. Since it is confined to the reinforced fiber and the resin member, the reinforced fiber and the resin member in the portion sandwiched between the support surface and the pressing surface can be efficiently heated and welded. Here, the shielding function of the pressing body can be exhibited by forming the pressing body itself with a material having a thermal conductivity smaller than, for example, 10 W / (m · K).

  Moreover, it is good to provide the press body side shielding means which exhibits the heat shielding function to the said press body. The pressing body side shielding means may be a pressing body side coating layer formed of a material having low thermal conductivity on the pressing surface, and has a low heat disposed between the reinforcing fiber and the pressing surface of the pressing body. You may provide the press body side film material of conductivity. Even in these cases, conduction of heat energy generated by ultrasonic vibration to the pressing body is prevented and heat energy is effectively confined in the reinforcing fiber and the resin member sandwiched between the support surface and the pressing surface, The reinforcing fiber and the resin member can be efficiently heated and welded.

  At this time, polytetrafluoroethylene (PTFE), perfluoroalkoxy fluororesin (PFA), tetrafluoroethylene / hexafluoropropylene copolymer (FEP), ethylene. Various fluororesins such as tetrafluoroethylene copolymer (ETFE) and resin materials with low thermal conductivity such as fluororesin containing glass fiber, Pyrogel (registered trademark) made by Nichias Co., Ltd. with low thermal conductivity, etc. It is desirable to select a material having a low thermal conductivity or a glass transition point or a high melting point.

  Moreover, the processing apparatus concerning this invention is a processing apparatus which processes a reinforced fiber. WHEREIN: The support body which has a support surface, the press body which has a press surface, and the super direction to the press direction orthogonal to the said support surface to the said press body. A resin member and the reinforcing fiber are overlapped and sandwiched between a vibration unit that applies sonic vibration, the support surface, and the pressing surface of the pressing body that is ultrasonically vibrated in the pressing direction by the vibration unit. In this state, a moving means for relatively moving the reinforcing fiber and the resin member and the pressing body is provided, and the support body has a shielding function that hardly transfers heat from the outside.

  According to such a configuration, the pressing surface with the reinforcing fiber and the resin member sandwiched between the supporting surface of the supporting body and the pressing surface of the pressing body that ultrasonically vibrates in the pressing direction orthogonal to the supporting surface. When the reinforcing fiber and the resin member are processed (for example, impregnation treatment) by moving the pressing portion of the reinforcing fiber along the longitudinal direction of the reinforcing fiber, ultrasonic vibration energy is applied to press the supporting surface and the pressing surface. The thermal energy generated in the reinforcing fiber and resin member sandwiched between the surfaces is prevented from escaping to the pressing body by the shielding function of the support, and the generated thermal energy is sandwiched between the supporting surface and the pressing surface. Since it is confined to the reinforced fiber and the resin member, the reinforced fiber and the resin member in the portion sandwiched between the support surface and the pressing surface can be efficiently heated and welded. Here, the shielding function of the support can be exhibited by forming the support itself with a material having a thermal conductivity smaller than, for example, 10 W / (m · K).

  Moreover, it is good to provide the support body side shielding means which exhibits the heat shielding function to the said support body. The support-side shielding means may be a pressing body-side coating layer formed of a material having low thermal conductivity on the support surface, and has a low heat disposed between the reinforcing fiber and the support surface of the support. You may provide the support side film material of conductivity. Even in these cases, conduction of heat energy generated by ultrasonic vibration to the support is prevented, and the heat energy is effectively confined in the reinforcing fiber and the resin member sandwiched between the support surface and the pressing surface, The reinforcing fiber and the resin member can be efficiently heated and welded.

  At this time, polytetrafluoroethylene (PTFE), perfluoroalkoxy fluororesin (PFA), tetrafluoroethylene / hexafluoropropylene copolymer (FEP), ethylene. Various fluororesins such as tetrafluoroethylene copolymer (ETFE) and resin materials with low thermal conductivity such as fluororesin containing glass fiber, Pyrogel (registered trademark) made by Nichias Co., Ltd. with low thermal conductivity, etc. It is desirable to select a material having a low thermal conductivity or a glass transition point or a high melting point.

  Moreover, it is good to further provide the pressing member which presses the said reinforced fiber after being pinched | interposed between the said support surface of the said support body, and the said press surface of the said press body, with respect to the said support surface.

  If comprised in this way, the reinforcement fiber processed (for example, impregnation process) by applying an ultrasonic vibration from a press body can be shape | molded with a pressing member, and the shape can be maintained. Moreover, the shape of the reinforced fiber after a process can be shape | molded by a pressing member in a suitable shape.

  Moreover, it is good to arrange | position with the clearance gap preset from the said pressing member and the said support surface.

  If comprised in this way, in a state where the presser member is arranged with a gap suitable for maintaining the molded state of the processed reinforcing fiber from the support surface, the processed reinforcing fiber is processed with respect to the support surface by the presser member. The pressed state of the reinforcing fiber after processing can be more reliably maintained by the pressing member. Further, the treated reinforcing fibers are pressed against the support surface in a state where the pressing member is disposed with a predetermined distance set in advance according to the target value of the thickness of the treated reinforcing fibers from the support surface. Thereby, the thickness of the reinforced fiber after a process can be adjusted accurately.

  The pressing member may press the reinforcing fiber against the support surface with a predetermined pressing force.

  By configuring in this way, by processing while pressing the reinforcing fibers with a predetermined pressure set in advance according to the thickness of the reinforcing fibers to be processed, the target value of the width of the reinforcing fibers after the processing, The width of the reinforcing fiber after the treatment can be adjusted with high accuracy.

  Moreover, it is good to provide the cooling means for pressing members which cools the said pressing member, You may further provide the cooling means for support bodies which cools the said support body.

  If comprised in this way, the reinforcing fiber after a process can be rapidly cooled and stabilized by the pressing member cooled by the pressing member cooling means and the support cooled by the supporting body cooling means.

  Moreover, it is good to further have a heating means for heating the reinforcing fiber before being processed by being sandwiched between the support surface of the support and the pressing surface of the pressing body.

  With this configuration, the reinforcing fiber preheated by the heating means can be satisfactorily processed. For example, in the case of performing an impregnation process, the resin member and the reinforcing fiber whose surface is melted by the thermal energy by ultrasonic vibration The adhesion can be further improved.

  The pressing surface of the pressing body may be arranged at a predetermined distance from the support surface.

  If comprised in this way, it will reinforce in the state where the press face was arranged with a predetermined interval set in advance according to the thickness of the reinforcing fiber to be processed, the target value of the thickness of the reinforcing fiber after processing, etc. By treating the fibers (for example, impregnation treatment), the thickness of the reinforced fibers after the treatment can be adjusted with high accuracy.

  The pressing body may press the reinforcing fiber against the support surface of the support with a predetermined pressure.

  With this configuration, processing is performed while pressing the reinforcing fibers with a pressing body with a predetermined pressure set in advance according to the thickness of the reinforcing fibers to be processed, the target value of the width of the reinforcing fibers after processing, and the like. By performing (for example, impregnation treatment), the width of the reinforced fiber after the treatment can be adjusted with high accuracy.

  Further, the moving means includes a metal member, the resin member, and the reinforcing fiber sequentially stacked between the support surface and the pressing surface of the pressing body that is ultrasonically vibrated in the pressing direction by the vibrating means. In this state, the reinforcing fiber, the resin member, the metal member, and the pressing body are relatively moved.

  If comprised in this way, the resin member between a metal member and a reinforcement fiber can be fuse | melted, and a reinforcement fiber and a metal member can be welded easily.

  Further, the surface of the metal member that faces the resin member may be roughened in advance.

  If comprised in this way, it will become easy to weld resin of the fuse | melted resin member to the roughened surface of a metal member, and a reinforced fiber and a metal member can be welded more firmly.

  In addition, a resin layer is formed by previously welding a resin on the roughened surface of the metal member, and the moving means includes the support surface and the pressing body of the support member without the resin member interposed therebetween. In the state where the metal member and the reinforcing fiber are overlapped and sandwiched with the resin layer disposed on the reinforcing fiber side between the pressing surface, the reinforcing fiber, the metal member, and the pressing body It is desirable to move relative to each other.

  If comprised in this way, a reinforcement fiber can be firmly welded to the metal member which formed the resin layer previously in the roughening surface, without interposing a resin member.

  According to the present invention, the reinforcing fiber is pressed by the pressing surface in a state where the reinforcing fiber is sandwiched between the supporting surface of the supporting member and the pressing surface of the pressing member that vibrates ultrasonically in the pressing direction orthogonal to the supporting surface. When processing the reinforcing fiber by moving the location, the reinforcing fiber is sandwiched between the support surface and the pressing surface by the heat energy generated by the ultrasonic vibration by the shielding function that shields the heat of the pressing body or the supporting body In addition, since it can be confined in the resin member, the reinforcing fibers and the resin member in the portion sandwiched between the support surface and the pressing surface can be efficiently heated and reliably welded.

(Processing equipment)
The processing apparatus 1 shown in FIG. 1 and FIG. 2 is provided between the support surface 21 of the support 2 and the pressing surface 35a of the horn 35 that ultrasonically vibrates in the arrow Z direction, which is the pressing direction orthogonal to the supporting surface 21. In a state where the unidirectional fiber bundle B is sandwiched, the unidirectional fiber bundle B travels in the direction of the arrow Y, which is the longitudinal direction, so that the pressing position of the unidirectional fiber bundle B by the pressing surface 35a is the longitudinal direction of the unidirectional fiber bundle B. By moving along a certain arrow Y direction and applying ultrasonic vibration in the arrow Z direction as the pressing direction from the pressing surface 35a along the arrow Y direction as the longitudinal direction to the unidirectional fiber bundle B, The fiber bundle B is continuously opened along the arrow Y direction which is the longitudinal direction.

  Further, in this embodiment, the processing apparatus 1 arranges the unidirectional fiber bundle B so as to overlap the resin film S (corresponding to the “resin member” of the present invention) between the support surface 21 and the pressing surface 35a. In this state, the unidirectional fiber bundle B and the resin film S are run in the direction of the arrow Y, which is the longitudinal direction, so that the resin film S superposed on both surfaces of the unidirectional fiber bundle B is melted and impregnated by ultrasonic vibration. Then, the unidirectional fiber bundle B is opened. Therefore, the unidirectional fiber bundle B on which the resin film S is superimposed is processed by the processing device 1 so that the filaments constituting the opened unidirectional fiber bundle B are aligned in a single direction with a predetermined width. A unidirectional prepreg P formed by impregnating the resin of the resin film S into the flat strip-like fiber bundle B * (see FIG. 3) is formed.

  The processing apparatus 1 includes a support 2, a head unit 3 including a resonator 31 that applies ultrasonic vibration in an arrow Z direction that is a pressing direction to the unidirectional fiber bundle B, and a resonator 31 supported by a support unit 33. Is supplied between the stage 2 and the head unit 3, and the unidirectional fiber bundle B in which the resin film S is overlapped on both surfaces thereof A supply means 5 and a control device (not shown) for controlling each part of the processing apparatus 1 are provided. The unidirectional fiber bundle B as the reinforcing fiber is formed by bundling each filament constituting carbon fiber, glass fiber, aramid fiber, etc., and the resin film S constituting the matrix resin is an epoxy resin, It is made of a thermosetting resin such as unsaturated polyester resin, or a thermoplastic resin such as polyolefin resin, aliphatic polyamide resin, or polyethylene terephthalate resin. As shown in FIG. 3, the resin film S is formed in a tape shape whose width Ws is slightly wider than the width Wb of the strip-shaped fiber bundle B * formed by opening the unidirectional fiber bundle B. ing.

  The support body 2 is disposed below the head section 3 and includes a horn 35 (corresponding to the “pressing body” of the present invention) in which the head section 3 includes a unidirectional fiber bundle B in which the resin film S is superimposed on both surfaces. The flat support surface 21 is sandwiched between the pressing surface 35a. In addition, the support body 2 is suitably formed with various materials, such as various metal materials, such as titanium, titanium alloy, iron, stainless steel, aluminum, aluminum alloys, such as duralumin, glass, ceramics, and resin.

  The support 2 may be provided with a heater (not shown). In this case, when the resin film S to which the ultrasonic vibration energy is applied is heated by heating the body of the support 2 to a predetermined temperature with the heater, the resin film S and the support 2 Since the thermal gradient generated between them can be relaxed, heat transfer from the heat-generated resin film S to the support 2 can be shielded. Thus, the heater provided in the support body 2 can be made to function as the support body side shielding means in this invention which shields the heat transfer to the support body 2 side. Further, the temperature of the heater 2 is increased to the ultrasonic vibration energy applied to the resin film S from the pressing surface 35a of the horn 35 by raising the temperature of the main body of the support 2 to a predetermined temperature by the heater. it can. If it does in this way, while suppressing excessive supply of the ultrasonic vibration energy to the resin film S, temperature can fully be raised and the resin film S can be fuse | melted reliably.

  The head unit 3 supports a resonator 31 having a resonator 31 (vibration means) that applies ultrasonic vibration in an arrow Z direction as a pressing direction to the resonator 31, and one end thereof connected to the resonator 31. Supporting means 33 is provided, and ultrasonic vibration is applied from the pressing surface 35a to the unidirectional fiber bundle B (resin film S) by the vibrator 32 ultrasonically vibrating the resonator 31 (horn 35).

  Specifically, the resonator 31 resonates with the ultrasonic vibration generated by the vibrator 32 controlled by the control device, and ultrasonically vibrates in the direction of the center axis (the pressing direction) of the arrow Z. Thus, a booster 34 and a horn 35 are provided, and the other end of the booster 34 and one end of the horn 35 are connected by a headless screw so that their central axes are coaxial.

  In this embodiment, for example, the booster 34 is formed to have a length of one wavelength of the resonance frequency so that the substantially center position in the direction of arrow Z in FIG. Yes. At this time, two positions that are a quarter wavelength away from each maximum amplitude point in the arrow Z direction correspond to the first and second minimum amplitude points of the booster 34, respectively. Moreover, the booster 34 is formed in the column shape whose cross-sectional shape is circular. The vibrator 32 is connected to one end of the booster 34 by a headless screw so as to be coaxial with the central axis of the booster 34.

  In addition, concave grooves are formed along the respective circumferential directions on the outer peripheral surface of the booster 34 at positions corresponding to the first and second minimum amplitude points, whereby the booster 34 (resonator 31) is supported by the support means 33. A gripped portion is formed to be gripped. In this embodiment, the gripped portion is formed so that the cross-sectional shape substantially orthogonal to the central axis of the booster 34 is an octagonal shape, but the cross-sectional shape is a circular shape or other polygonal shape. A gripped portion may be formed.

  The horn 35 that is a pressing body has a flat pressing surface 35 a that presses the unidirectional fiber bundle B (resin film S) in an arrow Z direction that is a pressing direction orthogonal to the support surface 21 of the support 2, and vibrates. The ultrasonic vibration is applied to the unidirectional fiber bundle B (resin film S) from the pressing surface 35a by resonating with the vibration of the child 32 and ultrasonically vibrating. The horn 35 is formed to have a half wavelength length of the resonance frequency so that both end positions in the arrow Z direction in FIG. 2 are maximum amplitude points, for example. At this time, the substantially center position of the horn 35 in the arrow Z direction corresponds to the third minimum amplitude point. As shown in FIGS. 2 and 3, the horn 35 is formed in a rectangular parallelepiped shape. And the pressing surface 35a of the horn 35 is the width direction substantially orthogonal to the arrow Z direction which is the pressing direction and the arrow Y direction which is the longitudinal direction with respect to the resin film S (the strip-shaped fiber bundle B * after opening). (Width Wh of horn 35 ≧ width Ws of resin film S ≧ width Wb of belt-like fiber bundle B *).

  In this embodiment, the resonator 31 has a resonance frequency of about 15 kHz to about 60 kHz, and a vibration amplitude (amplitude of expansion and contraction in the arrow Z direction) of about 2 μm to about 300 μm. The resonator 31 resonates with the ultrasonic vibration generated by the child 32 and ultrasonically vibrates, so that the arrow Z that is the pressing direction from the pressing surface 35a of the horn 35 to the unidirectional fiber bundle B (resin film S). Directional ultrasonic vibrations are applied. The resonator 31 (booster 34, horn 35) is formed of various metal materials generally used for forming a resonator, such as titanium, titanium alloy, aluminum alloy such as iron, stainless steel, aluminum, and duralumin. Is done.

  Further, a heater may be provided in the resonator 31 (horn 35). In this way, when the temperature of the resonator 31 (horn 35) is raised to a predetermined temperature by the heater, the resin film S and the resonator 31 are heated when the resin film S to which ultrasonic vibration energy is applied generates heat. Since the thermal gradient generated between the horn 35 and the horn 35 can be relaxed, heat transfer from the heat-generated resin film S to the resonator 31 (horn 35) can be shielded. Thus, the heater provided in the resonator 31 (horn 35) can function as a shielding means for shielding heat transfer to the resonator 31 (horn 35) side. Further, by raising the temperature of the resonator 31 (horn 35) with a heater to a predetermined temperature, the thermal energy of the heater is increased to the ultrasonic vibration energy applied to the resin film S from the pressing surface 35a of the horn 35. You can also. If it does in this way, while suppressing excessive supply of the ultrasonic vibration energy to the resin film S, temperature can fully be raised and the resin film S can be fuse | melted reliably.

  The support means 33 includes a base portion 36 and a clamp means 37, and supports the resonator 31 by holding the gripped portion of the booster 34 with the clamp means 37. The base portion 36 includes the pressurizing means 4. A screw hole to be screwed into the ball screw 42 is formed in the arrow Z direction.

  The clamping means 37 is provided at two locations of the base portion 36 so that the two gripped portions formed on the booster 34 can be gripped. Each of the clamp members 37 includes a first member for sandwiching the gripped portion of the booster 34 and A second member is provided. Specifically, the first member and the second member of the clamping means 37 are each provided with a recess having a shape that can be engaged with the cross-sectional shape of the gripped portion. Then, the first member of the clamping means 37 supported by the base portion 36 is formed in the concave groove forming the gripped portion so that the gripped portion of the booster 34 is held between the concave portions of the first member and the second member. The second member is inserted and the first member and the second member are fixed with bolts, whereby the gripped portion of the booster 34 is gripped by the clamp means 37.

  Note that the configuration of the support means 33 that supports the resonator 31 is not limited to the clamp means 37 that is fixed with bolts while holding (clamping) the gripped portion formed on the booster 34 as described above. Any configuration that can support the gripped portion of the booster 34, such as a mechanical clamping mechanism configured to be electrically controlled or a clamping mechanism that can be attached with one touch, may be used.

  The position of the gripped portion formed in the resonator 31 is not limited to the minimum amplitude point, and the gripped portion may be formed at an arbitrary position of the resonator 31. The configuration of the gripped portion is not limited to a configuration in which a concave groove is formed along the circumferential direction on the outer peripheral surface of the resonator 31. For example, a convex shape along the circumferential direction is formed on the outer peripheral surface of the resonator 31. As long as it can be gripped by the support means 33, such as a configuration in which a flange is formed, the gripped portion may be configured in any shape. Further, the gripped portion may be supported by the support means 33 via an elastic member such as an O-ring or a diaphragm.

  The pressurizing means 4 drives the resonator 31 supported by the support means 33 so that the pressing surface 35a of the horn 35 faces the support surface 21 of the support 2 in the direction of the arrow Z that is the pressing direction. 2, and a drive motor 41 and a ball screw 42. In addition, a guide 43 is coupled to a support (not shown) standing on a gantry (not shown), and the pressurizing means 4 is connected to the support and the guide 43 via a frame 44.

  Then, when the drive motor 41 rotates under the control of the control device, the guide (not shown) provided on the support means 33 slides along the convex rail 43a provided on the guide 43 in the arrow Z direction. The support means 33 screwed to the ball screw 42 while contacting is moved up and down in the direction of the arrow Z, which is the moving direction, so that the resonator 31 supported by the support means 33 is close to or from the support body 2. Separate.

  Further, the pressurizing unit 4 adjusts the driving torque of the driving motor 41 based on the control by the control device, thereby bringing the resonator 31 supported by the support unit 33 close to the support 2 with a predetermined pressurizing force. It is configured to be able to. Further, the support column is provided with a linear encoder (not shown), whereby the height of the head portion 3 in the arrow Z direction (pressing direction) is detected and driven by the control device based on the detection signal of the linear encoder. By controlling the motor 41, the height of the head unit 3 can be adjusted.

  The direction of the center axis of the resonator 31 is substantially the same as the screw hole formed in the base portion 36, that is, the direction of the center axis of the resonator 31 and the moving direction (pressing direction) of the resonator 31 by the pressurizing means 4. And the resonator 31 is supported by the support means 33 so that the pressing surface 35a of the horn 35 faces the support 2. Accordingly, when the base portion 36 is moved downward by the pressurizing means 4, the resonator 31 (horn 35) is driven in the direction of the arrow Z, which is the pressing direction, so as to come close to the support body 2 and thereby pressurize. The pressure applied by the means 4 is applied to the unidirectional fiber bundle B (resin film S) supported on the support surface 21 of the support 2 from the pressing surface 35a. That is, by being controlled by the pressurizing means 4, the unidirectional fiber bundle B (resin film S) is pressed against the support surface 21 of the support 2 by the pressing surface 35 a of the horn 35 that vibrates ultrasonically. Is done.

  In this embodiment, the drive motor 41 is controlled by the control device such that the unidirectional fiber bundle B (resin film S) is pressed against the support surface 21 with a predetermined constant pressure by the pressing surface 35a. . Further, the height position in the arrow Z direction that is the pressing direction of the resonator 31 (base portion 36) is such that the pressing surface 35a and the support surface 21 when the resonator 31 extends to the maximum as shown by L in FIG. The drive motor 41 is controlled by the control device so that the resonator 31 does not move beyond the position H to the support body 2 side when the distance reaches a position H at which the predetermined gap G is reached. In addition, the magnitude of the pressure applied to the unidirectional fiber bundle B by the pressing surface 35a and the size of the gap G between the pressing surface 35a and the support surface 21 are the width and thickness of the strip-shaped fiber bundle B * after opening, What is necessary is just to set an optimal value suitably according to the width | variety and thickness of the direction prepreg P. FIG. For example, by repeatedly performing a processing test on the unidirectional fiber bundle B or the resin film S, an optimal pressure or gap G value may be set. Further, the drive motor 41 is controlled by the control device so that the applied pressure is constant until the height in the arrow Z direction that is the pressing direction of the resonator 31 reaches the position H, and the arrow that is the pressing direction of the resonator 31. The drive motor 41 may be controlled by the control device so that the resonator 31 stops when the height in the Z direction reaches the position H.

  As shown in FIG. 1, the supply means 5 (corresponding to the “moving means” in the present invention) winds and holds the first supply roller 51 that winds and holds the unidirectional fiber bundle B and the resin film S, respectively. Second and third supply rollers 52 and 53, a drawing roller 54, a tension adjusting roller 55, and a storage roller 56 are provided. The unidirectional fiber bundle B and the two resin films S are drawn from the supply rollers 51 to 53 by being nipped by the driving roller 54a and the driven roller 54b that rotate in the direction of the arrow of the drawing roller 54, and both the resin films A unidirectional fiber bundle B sandwiched between S is supplied between the pressing surface 35 a of the horn 35 and the support surface 21 of the support 2.

  At this time, the unidirectional fiber bundle B in which the resin films S are overlapped on both surfaces is driven by the driving roller 55a and the driven roller 55b that rotate in the arrow direction of the tension adjusting roller 55 disposed on the downstream side of the head portion 3. By being nipped, the belt travels in the direction of the arrow Y, which is the longitudinal direction, while being sandwiched between the pressing surface 35a and the support surface 21 while adjusting its tension. Therefore, in this embodiment, since the unidirectional fiber bundle B (resin film S) and the horn 35 move relatively in the arrow Y direction which is the longitudinal direction, the unidirectional fiber bundle B (resin film S) is pressed against the pressing surface. The part pressed by the predetermined fixed pressure by 35 moves along the arrow Y direction which is the longitudinal direction of the unidirectional fiber bundle B. The unidirectional prepreg P formed by passing the unidirectional fiber bundle B in which the resin films S are overlapped on both surfaces passes between the pressing surface 35a of the horn 35 and the support surface 21 of the support 2 is stored. It is wound around a roller 56 and stored. Note that the resin film S may be overlapped only on one side of the unidirectional fiber bundle B by providing only one of the second and third supply rollers 52 and 53.

  The control device sandwiches the resin film S (unidirectional fiber bundle B) between the support surface 21 of the support 2 and the pressing surface 35a of the horn 35 by controlling each part of the processing device 1 as described above. In this state, the resonator 31 (horn 35) is ultrasonically vibrated by the vibrator 32. As a result, the control device applies ultrasonic vibration energy to the resin film S from the pressing surface 35a to cause the resin film S to generate heat and melt the resin film S.

(Opening and impregnation treatment)
Next, an example of the fiber opening / impregnation process performed in the processing apparatus 1 will be described.

  First, a unidirectional fiber bundle B is prepared in which filaments constituting predetermined reinforcing fibers are bundled in a band shape. Then, the unidirectional fiber bundle B is applied to the support surface 21 of the support 2 by the pressing surface 35a of the horn 35 that vibrates ultrasonically with the resin film S having a predetermined thickness superimposed on both surfaces. As shown in FIG. 3, the width of the unidirectional fiber bundle B is increased to the width Wb, and the thickness is reduced to a predetermined thickness. A unidirectional prepreg P formed by impregnating the formed belt-like fiber bundle B * with the resin of the resin film S is formed.

  As described above, in this embodiment, there is one direction between the support surface 21 of the support 2 and the pressing surface 35a of the horn 35 that ultrasonically vibrates in the arrow Z direction, which is the pressing direction orthogonal to the supporting surface 21. The unidirectional fiber bundle B is opened by moving the pressed portion of the unidirectional fiber bundle B by the pressing surface 35a along the arrow Y direction, which is the longitudinal direction of the unidirectional fiber bundle B, with the fiber bundle B interposed therebetween. Can be fine. Therefore, for example, when comparing conventional techniques using airflow, a strong tension can be applied to the unidirectional fiber bundle B when opening, so that the unidirectional fiber bundle B can be stably opened at high speed. Can be fine.

  In general, the strip-shaped fiber bundle B * after opening is unstable and easily entangled, but the unidirectional fiber bundle B and the resin film S are overlapped between the support surface 21 and the pressing surface 35a. In the state of being arranged, the unidirectional fiber bundle B (resin film S) is run in the arrow Y direction which is the longitudinal direction, whereby the unidirectional fiber bundle B is opened and simultaneously the resin in which the resin film S is melted is strip-shaped. The fiber bundle B * can be impregnated. Accordingly, it is not necessary to prepare both the opening device and the impregnation device as in the prior art, and the unidirectional prepreg P can be formed in one step, so that the processing cost of the unidirectional fiber bundle B is reduced. be able to. In addition, when physical ultrasonic vibration is applied from the horn 35, the resin of the resin film S and the belt-like fiber bundle B * come into contact with each other, thereby reacting the bonding interface between each filament constituting the reinforcing fiber and the resin. It can be promoted to form a good bonded state, and the resin of the resin film S can be satisfactorily impregnated into the band-like fiber bundle B *. Therefore, the physical properties of a molded product using the unidirectional prepreg P can be improved. In addition, since the band-like fiber bundle B * is impregnated with the resin simultaneously with the opening, there is no possibility of fluffing and the like in the band-like fiber bundle B * after opening, and the fiber bundle B * after opening is handled. Is easy.

  Further, the unidirectional fiber bundle B with a predetermined pressure set in advance according to the thickness of the unidirectional fiber bundle B to be processed and the target value of the width Wb and thickness of the strip-shaped fiber bundle B * after the fiber opening process. By opening the fiber while pressing, the width Wb and thickness of the fiber bundle B * after opening can be adjusted with high accuracy.

  In addition, the thickness of the unidirectional fiber bundle B to be processed, the thickness of the band-like fiber bundle B * after the fiber opening process, and the target value of the width Wb are set to be larger than the predetermined gap G set in advance. By opening the unidirectional fiber bundle B in a state where the pressing surface 35a is arranged so that the interval is not narrowed, the thickness and width Wb of the strip-shaped fiber bundle B * after the fiber opening can be accurately adjusted. The resonator 31 is fixedly arranged at a position H in the arrow Z direction that is the pressing direction so that the distance between the pressing surface 35a and the support surface 21 at the time of maximum extension of the horn 35 that vibrates ultrasonically becomes the predetermined gap G. In this state (see FIG. 2), the unidirectional fiber bundle B (resin film S) may be run in the arrow Y direction which is the longitudinal direction. Even in this way, the thickness and width Wb of the strip-shaped fiber bundle B * after opening can be adjusted with high accuracy.

Second Embodiment
A processing apparatus according to a second embodiment of the present invention will be described with reference to FIG. FIG. 4 is a side view showing a processing apparatus according to the second embodiment of the present invention.

  The processing apparatus 1a shown in FIG. 4 differs from the first embodiment described above in that the impregnation process is performed in the impregnation apparatus 6 as shown in FIG. That is, after the unidirectional fiber bundle B is opened by passing between the pressing surface 35a and the support surface 21 in a state where the resin film S is not superposed, the resin film S is applied to the belt-like fiber bundle B *. The impregnation processing is performed in the impregnation apparatus 6 by being superimposed. Since other configurations and operations are the same as those of the first embodiment described above, the description of the configurations and operations is omitted by citing the same reference numerals.

  As shown in FIG. 4, the impregnation device 6 is configured to be able to press a belt-like fiber bundle B * having a resin film S superimposed on both sides from above and below, and rotates in the direction of the arrow in the figure. Units 61 and 62, and a heating mechanism 63 and a cooling mechanism 64 disposed inside the belt units 61 and 62 are provided. The heating mechanism 63 is disposed on the upstream side, and the cooling mechanism 64 is disposed on the downstream side. In the impregnation apparatus 6 configured as described above, when the belt-like fiber bundle B * with the resin film S superimposed on both sides passes, the heating mechanism 63 is pressurized while being pressurized by the belt units 61 and 62 on the upstream side. The belt-shaped fiber bundle B * is impregnated with the resin of the resin film S melted by heating. Then, on the downstream side, the resin impregnated in the fiber bundle B * is solidified by being cooled by the cooling mechanism 64 while being pressurized by the belt units 61 and 62, and the unidirectional prepreg P is formed. Note that, similarly to the first embodiment described above, the tension adjusting roller 55 may be further provided at an optimal place as appropriate.

  Even in this configuration, the unidirectional fiber bundle B is opened by opening the unidirectional fiber bundle B by passing between the pressing surface 35a and the support surface 21 as in the first embodiment. Can be processed and opened at high speed stably. Further, by stably opening the unidirectional fiber bundle B, the thickness of the strip-shaped fiber bundle B * impregnated with the resin (impregnation distance: the number of filaments constituting the reinforcing fiber) can be reduced. The fiber bundle B * can be impregnated with the resin in a short time, the generation of voids can be suppressed, and incomplete impregnation can be prevented. Therefore, the physical properties of a molded product using the unidirectional prepreg P can be improved.

<Third Embodiment>
A processing apparatus according to a third embodiment of the present invention will be described with reference to FIG. FIG. 5 is a perspective view of a part of the processing apparatus according to the third embodiment of the present invention. In FIG. 5, the resin film S disposed on the lower surface side of the belt-like fiber bundle B * and the support 2 are omitted as in FIG. 3.

  The processing apparatus 1b shown in FIG. 5 is different from the above-described second embodiment in that the configuration of the impregnation apparatus 7 is different as shown in FIG. Since other configurations and operations are the same as those of the first embodiment described above, the description of the configurations and operations is omitted by citing the same reference numerals.

  As shown in FIG. 5, the impregnation apparatus 7 includes a horn 135 (corresponding to the “pressing body” of the present invention) having substantially the same configuration as the horn 35 used for the fiber opening process. Then, the band-shaped fiber bundle B * overlaid with the resin film S passes between the pressing surface 135a of the horn 135 of the impregnation device 7 and the support surface 21 of the support body 2, whereby the first embodiment described above is performed. Similarly to the form, the belt-shaped fiber bundle B * is impregnated with the resin of the resin film S melted by applying ultrasonic vibration from the pressing surface 135a, and the prepreg P is formed.

  With this configuration, the resin sheet S can be heated at high speed and melted by applying ultrasonic vibration energy to vibrate and rotate the resin molecules to promote molecular motion and generate heat. Therefore, compared with the conventional technique using a pressure device such as a nip roller or the configuration of the second embodiment described above, the impregnation time can be further shortened by applying ultrasonic vibration, and the impregnation device. It is possible to improve the impregnation capacity of 7 (treatment device). Accordingly, the unidirectional fiber bundle B (band-like fiber bundle B *) can be stably impregnated and impregnated with a molten resin. Compared with the conventional technique using a pressure device such as a nip roller or the configuration of the second embodiment described above, the impregnating device 7 having a compact configuration makes the resin sheet into the fiber bundle B (band-shaped fiber bundle B *). A matrix resin such as S can be impregnated. Further, as in the first embodiment described above, since the ultrasonic vibration is applied and the impregnation treatment is executed, the reaction at the bonding interface between each filament constituting the reinforcing fiber and the resin is promoted to achieve good bonding. Thus, the belt-shaped fiber bundle B * can be satisfactorily impregnated with the resin of the resin film S. Therefore, the physical properties of a molded product using the unidirectional prepreg P can be improved.

  Similarly to the horn 35, an actuator such as a drive motor is provided so that the unidirectional fiber bundle B (resin film S) is pressed against the support surface 21 with a predetermined constant pressure by the pressing surface 135 a of the horn 135. The pressurizing means provided may be controlled by a control device. Similarly to the horn 35, the height position in the arrow Z direction, which is the pressing direction of the horn 135, is the pressing surface 135a and the support surface 21 when the horn 135 is extended to the maximum as shown by L in FIG. When the distance reaches a position H at which the predetermined gap G is reached, the pressurizing means may be controlled by the control device so that the horn 135 does not move beyond the position H to the support 2 side. Further, the size of the pressure applied to the unidirectional fiber bundle B (resin sheet S) by the pressing surface 135a and the size of the gap G between the pressing surface 135a and the support surface 21 are determined by the width of the opened fiber bundle B *. What is necessary is just to set an optimal value suitably according to a width | variety and thickness, and the width | variety and thickness of the unidirectional prepreg P. FIG. Further, the pressurizing means is controlled by the control device so that the applied pressure is constant until the height in the arrow Z direction as the pressing direction of the horn 135 reaches the position H, and the arrow Z direction as the pressing direction of the horn 135 is controlled. The pressurizing means may be controlled by the control device so that the horn 135 stops when the height at reaches the position H.

  Furthermore, it is not necessary for the processing apparatus 1b to include a fiber opening device (support 2, head part 3). In this case, the unidirectional fiber bundle B (band-shaped) opened by a device other than the processing device 1b is used. What is necessary is just to comprise the supply means 5 so that the fiber bundle B *) may be supplied to the impregnation apparatus 7 of the processing apparatus 1b.

Further, a fluororesin or other material having a glass transition temperature of 60 ° C. or higher or a melting point of 250 ° C. or higher may be used for the heat insulating films Ia and Ib. At this time, when the melting point of the resin film S (resin member) is low, it is preferable to use the above-described fluororesin or the like, but when the melting point of the resin film S (resin member) is high, stainless steel, iron, It is desirable to use a thin metal plate such as aluminum, titanium, titanium alloy, manganese, nichrome (Ni-Cr), or bismuth. Furthermore, the above-described fluororesin coated on the pressing surface 35a side and the support surface 21 side of these metal thin plates, or those coated on both surfaces of the metal thin plates may be used.

  By the way, conventionally, when ultrasonic vibration is applied from the pressing surface 35a of the horn 35, the objects to be processed such as the resin film S and the resin plate S ′, which are superimposed, are rubbed together to generate frictional heat and the resin is melted. It was thought. The inventor of the present application observed by thermography a resin-made object to which ultrasonic vibration is applied from the pressing surface 35a of the horn 35, and examined the temperature distribution of the object to be processed in detail. As a result, the inventor of the present application has found that the temperature of the edge portion of the workpiece to which the pressing surface 35a is not in contact has also increased. Similar to the principle of the microwave oven, the ultrasonic vibration energy is applied from the pressing surface 35a of the horn 35 to the object to be processed such as the resin film S and the resin plate S ′, so that the resin molecules vibrate and rotate. This is because the molecular motion is promoted and the temperature of the whole object to be processed rises.

  Further, the inventor of the present application has found that the horn 35 is still heated when the pressing surface 35a of the horn 35 is separated from the workpiece after the ultrasonic treatment. This is presumably because the heat energy generated in the object to be processed by applying ultrasonic vibration energy is conducted to the horn 35 and escapes to the outside of the object to be processed, so that the temperature of the horn 35 is raised. From these consideration results, the inventor of the present application processes the object to be processed by efficiently using the ultrasonic vibration energy when applying the ultrasonic vibration energy from the pressing surface 35a of the horn 35 to process the object. In order to achieve this, the ultrasonic vibration energy is applied to prevent the thermal energy generated in the entire workpiece from escaping to the horn 35 or the support 2, and the generated thermal energy is confined in the workpiece. I learned that is important.

  Therefore, according to this embodiment, when the resin film S is heated by applying ultrasonic vibration energy to vibrate and rotate the resin molecules to promote molecular motion, the resin film S and the horn 35 and Since heat transfer to the support 2 is shielded, heat generated in the resin film S can be prevented from conducting to the support 2 and the horn 35 and escaping, and heat can be stored in the resin film S. Can do. Therefore, the thermal energy generated in the resin film S by applying ultrasonic vibration can be confined in the resin film S. As a result, the resin film S can be obtained without applying excessive ultrasonic vibration energy. The resin film S can be reliably heated up to a predetermined temperature and melted by ultrasonic vibration energy having a moderate size that does not damage the resin film.

  In addition, in the state where the resin film S (unidirectional fiber bundle B) is sandwiched between the support surface 21 of the support 2 and the pressing surface 35a of the horn 35 that is ultrasonically vibrated, the pressing portion by the pressing surface 35a is the resin film. When moved continuously at a predetermined speed along the arrow Y direction, which is the longitudinal direction of S, the position on the resin film S to which ultrasonic vibration energy is applied (injected) moves from moment to moment. Then, since heat energy generated by applying ultrasonic vibration energy is conducted to the support 2 and the horn 35 and escapes, the pressing surface 35a of the resin film S efficiently utilizes the ultrasonic vibration energy. The temperature at the point of contact cannot be raised. On the other hand, the ultrasonic vibration energy is efficiently utilized by shielding heat transfer from the resin film S to the horn 35 and the support 2 and confining the heat energy in the resin film S as in this embodiment. The temperature of the location where the pressing surface 35a of the resin film S is in contact can be raised. Therefore, by using the horn 35 having the pressing surface 35a smaller than the range that requires heating and continuously moving the pressing portion by the pressing surface 35a, the resin film S or resin plate having a larger area than the pressing surface 35a. A resin workpiece such as S ′ can be processed.

<Ninth Embodiment>
A processing apparatus 1g according to a ninth embodiment of the present invention will be described with reference to FIG. FIG. 13 is a side view of a part of the processing apparatus according to the ninth embodiment of the present invention.

  In this embodiment, as shown in FIG. 13, a metal member M such as aluminum (Al), copper (Cu), iron (Fe), etc., and a unidirectional prepreg (UD tape) and carbon fiber (CF) filaments. A reinforcing fiber RF impregnated with a resin is bonded to the woven or knitted fabric, cloth, nonwoven fabric, etc., plain-woven with the resin.

  As shown in FIG. 13, the metal member M, the resin member S, and the reinforcing fiber RF are sequentially stacked between the support 2 and the horn 135, and ultrasonic waves are applied while applying a predetermined pressure by the horn 135. Vibration is applied, the resin member S is melted by thermal energy by ultrasonic vibration, and the reinforcing fiber RF is welded to the metal member M to be joined. At this time, in comparison with the above-described sixth embodiment, the resin plate S ′ in FIG. 11 is thinned to form the resin member S in FIG. 13, and this resin member S is superimposed on the metal member M. In a state where the reinforcing fiber RF is overlaid thereon, ultrasonic waves are generated by the horn 135 while the metal member M, the resin member S, and the reinforcing fiber RF in the overlaid state are moved together by moving means (not shown). By being applied, the resin member S is melted, and the reinforcing fiber RF is bonded to the metal member M.

  And as shown in FIG. 13, the belt-shaped heat insulating film Ia is formed between the pressing surface 135a of the horn 135 and the reinforcing fiber RF by a plurality of rollers 11a1, 11a2, 11a3, 11a4, and 11a5 constituting the pressing body side shielding means 11a. The ultrasonic wave is applied while shielding the heat transfer to the horn 135 by moving the thermal energy, and the thermal energy generated by the ultrasonic vibration is sandwiched between the support surface 21 of the support 2 and the pressing surface 135a of the horn 135. The metal member M, the resin member S, and the reinforcing fiber RF are effectively confined, and the resin member S is melted to join the reinforcing fiber RF to the metal member M. In order to move the heat insulating film Ia, the five rollers 11a1 to 11a5 are not necessarily required as described above. In short, the heat insulating film Ia is moved between the pressing surface 135a of the horn 135 and the reinforcing fiber RF. If you can.

  Here, the heat insulating film Ia is made of polytetrafluoroethylene (PTFE), perfluoroalkoxy fluororesin (PFA), tetrafluoroethylene / hexafluoropropylene copolymer (FEP), ethylene, as in the eighth embodiment. -Resin materials with low thermal conductivity such as various fluororesins such as tetrafluoroethylene copolymer (ETFE) and fluororesin with glass fiber, Pyrogel (registered trademark) manufactured by NICHIAS Corporation with low thermal conductivity For example, it is made of a material having a low thermal conductivity.

  In addition, as shown in FIG. 13, the holding member 9b which has a pressing surface similarly to the holding member 9a of FIG. 11 is arrange | positioned in the downstream of the metal member M, the resin member S, and the reinforced fiber RF which are moved by a moving means. The reinforcing fiber RF is pressed against the support surface 21 of the support 2 while the pressing surface of the pressing member 9b and the reinforcing fiber RF are brought into sliding contact with each other.

  By the way, the resin member S to be overlaid on the metal member M is a resin layer previously formed on the metal member M as shown in FIG. 14A, or is bonded in advance as shown in FIG. 14B. Any of them may be used. As a method of previously forming a resin layer as the resin member S on the metal member M as shown in FIG. 14A, the metal member M is heated to the melting temperature (including heating by ultrasonic vibration energy) to form the metal member M. There are a technique in which the OH group is formed on the upper surface of the metal member M and a technique in which the resin member S is reacted with the formed OH group to form it by so-called chemical bonding.

  At this time, as shown in FIG. 15A, the upper surface of the metal member M is roughened in advance by etching or the like to form a roughened surface AM, and a resin layer as the resin member S is formed on the roughened surface AM. It is good to form in advance, and in this way, the adhesive strength of the resin member S to the metal member M can be improved. Moreover, as shown in FIG.15 (b), the roughening surface AM may be formed in the upper surface of the metal member M, and you may make it overlap | superpose the resin member S without adhering beforehand. As a method of forming the resin layer as the resin member S on the roughened surface AM of the metal member M as shown in FIG. 15A, the resin member S is heated to a melting temperature (including heating by ultrasonic vibration energy). In addition to the method of welding and forming on the roughened surface AM of the metal member M, an OH group is formed on the roughened surface AM of the metal member M, and the resin member S is reacted with the formed OH group. There is a method of forming by chemical bonding.

  Further, as in the case of FIG. 9, the pressing member 9 b may be disposed with a preset gap from the support surface 21 of the support 2, and the pressing member 9 b is pressed with a predetermined pressing force. It is good to do so. In this way, with the presser member 9b disposed with a gap suitable for maintaining the molded state of the processed reinforcing fiber RF from the support surface 21, the presser member 9b allows the processed reinforcing fiber RF to be supported on the support surface. By pressing against 21, the molded state of the reinforcing fiber after the treatment can be more reliably maintained by the pressing member 9b. Further, the processed reinforcing fiber RF is supported in a state where the pressing member 9b is disposed with a predetermined distance set in advance according to the target value of the thickness and width of the processed reinforcing fiber RF from the support surface 21. By pressing the surface 21 with a predetermined pressing force, the thickness and width of the treated reinforcing fiber RF can be accurately adjusted.

  Therefore, according to the above-described embodiment, the resin member S between the metal member M and the reinforcing fiber RF can be melted and the reinforcing fiber RF and the metal member M can be easily welded.

  As a modification of the ninth embodiment, as shown in FIG. 16, the heat insulating film Ia may be arranged to move below the pressing member 9b. In this case, the number of rollers 11a1 to 11a4 is one less than that in FIG.

  Further, the holding member 9b in FIGS. 13 and 16 may be provided with air-cooled and water-cooled pressing body cooling means as in the sixth embodiment.

  Further, as a tenth embodiment of the present invention, a rotary horn RH held rotatably as shown in FIG. 17 may be used instead of the horns 35 and 135 in the processing apparatuses 1a to 1h.

  Furthermore, the present invention is not limited to the above-described embodiments, and various modifications other than those described above can be made without departing from the spirit of the present invention. For example, the configurations of the above-described embodiments may be combined in any way. For example, by moving the horns 35 and 135 (resonator 31) in the direction of arrow Y, which is the longitudinal direction, the pressing location of the unidirectional fiber bundle B by the pressing surfaces 35a and 135a of the horns 35 and 135 is moved. Also good. Further, by moving both the horns 35 and 135 (resonator 31) and the unidirectional fiber bundle B in the direction of the arrow Y, which is the longitudinal direction, the unidirectional fibers by the pressing surfaces 35a and 135a of the horns 35 and 135 are obtained. You may make it the press location of reinforcing fibers, such as bundle B, move.

  Further, by adding a cylinder to the pressurizing means 4 described above, the pressure applied to the reinforcing fibers such as the unidirectional fiber bundle B by the pressing surface 35a of the horn 35 can be set using the differential pressure of the cylinder. Good.

  In the second and third embodiments described above, the configuration of the impregnation apparatus is not limited to the above-described example, and the impregnation process may be performed by a generally used impregnation apparatus.

  Further, the configuration of the pressing body and the shape of the pressing surface is not limited to the configuration of the horns 35 and 135 described above, but has a flat pressing surface, and the unidirectional fiber bundle B extends at least in the width direction. The pressing body may be configured in any shape as long as it can be pressed against the support surface 21 by the pressing surface. For example, the horns 35 and 135 can be configured such that the side view shape tapers in a beak shape toward the pressing surfaces 35a and 135a. Further, for example, the pressing surface is uniaxial with respect to the support surface 21 in the width direction of the object to be processed such as the unidirectional fiber bundle B (strip-shaped fiber bundle B *), the resin film S, and the resin plate S ′. If the structure allows pressing, the pressed portion of the object to be processed by the pressing surface is scanned (moved) once in a predetermined direction (for example, a direction substantially perpendicular to the longitudinal direction of the pressing surface), and the object to be processed is spread over the entire surface. Can be processed.

  Further, the pressurizing unit 4 is not limited to the above-described configuration. If the resonator 31 can be moved, the pressurizing unit 4 may be changed by using a known actuator such as a linear motor or a cylinder. It may be configured.

  Further, the arrangement positions of the pressing body and the support body are not limited to the above-described examples arranged in the vertical direction toward the paper surface of FIG. 1, and the vertical positions of the pressing body and the support body are interchanged. Alternatively, the pressing body and the support body may be arranged side by side in the left-right direction toward the paper surface of FIG.

  In addition, various fluororesins such as polytetrafluoroethylene (PTFE) mentioned as the material of the heat insulating film, materials having low thermal conductivity such as zirconia, or materials having a glass transition temperature of 60 ° C. or higher and a melting point of 250 ° C. or higher. The insulating coating layer formed by the above may be formed on the surfaces of the pressing surfaces 35a and 135a of the horns 35 and 135. Even in this configuration, heat transfer from the resin film S or the resin plate S ′ to the horns 35 and 135 can be shielded by the heat insulating coating layer, and this is caused by applying ultrasonic vibration energy. Since heat energy can be confined in the resin film S and the resin plate S ′, the resin film S and the resin plate S ′ can be processed using the ultrasonic vibration energy efficiently. Thus, the heat insulating coating layer provided on the resonator 31 (horns 35, 135) can function as a shielding means for shielding heat transfer to the resonator 31 (horns 35, 135) side.

  In addition, various fluororesins such as polytetrafluoroethylene (PTFE), zirconia, (fine) ceramics, glass and other materials with low thermal conductivity, or materials having a glass transition temperature of 70 ° C. or higher and a melting point of 250 ° C. or higher. The heat insulating coating layer formed by the above may be formed on the surface of the support surface 21 of the support 2. Even with this configuration, the heat transfer from the resin film S or the resin plate S ′ to the support 2 can be shielded by the heat insulating coating layer, and this is caused by applying ultrasonic vibration energy. Since heat energy can be confined in the resin film S and the resin plate S ′, the resin film S and the resin plate S ′ can be processed using the ultrasonic vibration energy efficiently. Thus, the heat insulating coating layer provided on the support 2 can function as a shielding means for shielding heat transfer to the support 2 side.

  Further, the horns 35 and 135 as the pressing bodies and the support 2 itself are made of a material having a thermal conductivity lower than 10 W / (m · K), such as a titanium alloy (for example, a thermal conductivity of 7.5 W / (m -It may be formed of Ti-6Al-4V) or the like of K). The support 2 is made of a material such as quartz (8 W / (m · K)), glass (1 W / (m · K)), fine ceramics (mullite, forsterite, cordierite, zirconia, steatite, etc.) It may be formed. Even if comprised in this way, since the thermal conductivity of the horns 35 and 135 and the support body 2 are all set to be small, the thermal energy generated by the application of ultrasonic vibration energy is reduced to the resin film S or It is possible to prevent the resin plate S ′ from escaping through conduction to the horns 35 and 135 and the support 2. Therefore, since the heat energy generated by applying ultrasonic vibration energy can be confined in the resin film S and resin plate S ′, the resin film S and resin plate S can be efficiently utilized. Can handle '. Thus, each of the horns 35 and 135 and the support body 2 which are pressing bodies can exhibit the shielding function which shields the transmission of the heat from the outside.

  Moreover, the heater may be provided in the horn 135 with which the impregnation apparatus 7 (processing apparatus) of FIG.5, FIG.7, FIG.8, FIG.10 and FIG. In this way, by heating the horn 135 to a predetermined temperature with the heater, the resin film S or the resin plate S when the resin film S or the resin plate S ′ to which the ultrasonic vibration energy is applied generates heat. Since the thermal gradient generated between 'and the horn 135 can be relaxed, heat transfer from the heat-generated resin film S or resin plate S' to the horn 135) can be shielded. Thus, the heater provided in the horn 135 can function as a shielding means for shielding heat transfer to the horn 135 side. Further, by heating the horn 135 to a predetermined temperature by the heater, the thermal energy of the heater is increased to the ultrasonic vibration energy applied from the pressing surface 135a of the horn 135 to the resin film S or the resin plate S ′. You can also. In this way, the resin film S and the resin plate S ′ are reliably melted by sufficiently raising the temperature while suppressing excessive supply of ultrasonic vibration energy to the resin film S and the resin plate S ′. Can do.

  Further, between the support surface 21 of the support 2 and the unidirectional fiber bundle B (resin sheet S, resin plate S ′), the pressing surfaces 35a, 135a of the horns 35, 135 and the unidirectional fiber bundle B (resin sheet S). , A release sheet formed of a resin having excellent release properties such as a fluororesin, and a release sheet formed of a metal such as titanium, titanium alloy, copper, and stainless steel. It may be arranged. If a release sheet formed of metal is used, ultrasonic vibration can be transmitted to the unidirectional fiber bundle B (resin sheet S, resin plate S ′) more reliably.

  Further, in the above-described embodiment, as the reinforcing fiber impregnated with the resin, the unidirectional fiber bundle B (including the belt-shaped fiber bundle B *) in which the filaments constituting the reinforcing fiber are bundled in a bundle shape or the unidirectional prepreg P (UD tape) has been described as an example, but the reinforcing fiber impregnated with resin is not limited to the above-described unidirectional fiber bundle B or unidirectional prepreg P (UD tape). For example, a sheet in which the filaments constituting the reinforcing fibers are plain woven, a woven fabric, a cloth, a nonwoven fabric, a knitted fabric (including those impregnated with a resin), and the filaments constituting the reinforcing fibers are bundled in a bundle. Sheets in which directional fiber bundles B (including belt-shaped fiber bundles B *) are plain woven, woven fabrics, cloths, nonwoven fabrics, knitted fabrics (including those impregnated with resin), sheets in which unidirectional prepregs P are plain woven, You may make it impregnate resin of resin members (matrix resin), such as resin sheet S and resin board S ', to the molded object by which the unidirectional prepreg P was shape | molded in the shape of a blade.

  Further, the resin impregnated in the reinforcing fibers may be impregnated in other reinforcing fibers as a matrix resin (resin member). At this time, when the resin impregnated in the reinforcing fibers is impregnated in other reinforcing fibers as a matrix resin (resin member), the other reinforcing fibers may already be impregnated with another matrix resin.

  Further, in each of the above-described embodiments, the support 2 may be provided with an air-cooled or water-cooled support cooling means as shown in FIG. If it carries out like this, the reinforcement fiber after a process can be rapidly cooled and stabilized by the support body cooled by the cooling means for support bodies.

  Moreover, this invention can be widely applied with respect to the processing apparatus which processes a reinforced fiber.
