　熱可塑性複合材を賦形するにあたり、加圧冷却を連続的なプレス加工で行うことが考えられる。しかしながら、プレス方式では、冷却が完了するまで所定位置で金型を保持する必要があり、この間は熱可塑性複合材を移動させれらない。このため、高速成形技術へのニーズに十分に対応できない可能性がある。 When shaping the thermoplastic composite material, it is conceivable to perform pressure cooling by continuous press working. However, in the press method, it is necessary to hold the die in a predetermined position until cooling is completed, during which the thermoplastic composite cannot be moved. Therefore, it may not be possible to sufficiently meet the needs for high-speed molding technology.
　このような課題を解消するために、循環する無端ベルトそのものを型として、２つのベルトによって熱可塑性複合材を挟み込むことが考えられる。しかし、型にある程度の高さ寸法が必要な場合（すなわち、ベルトにある程度の厚みが必要な場合）、折り返し部においてベルトの内側と外側とで周長差が生じてベルトが破断する可能性がある。このため、無端ベルトそのものを型とする方法は現実的ではない。 In order to solve such a problem, it is conceivable to use the circulating endless belt itself as a mold and sandwich the thermoplastic composite material between the two belts. However, if the mold requires a certain height dimension (that is, the belt needs a certain thickness), there is a possibility that the belt will break due to a difference in circumference between the inside and outside of the belt at the folded part. is there. Therefore, the method of using the endless belt itself as a mold is not realistic.
　本開示はこのような事情に鑑みてなされたものであって、熱可塑性複合材を移動させたまま連続的に加圧冷却できる加圧冷却機構、成形治具及び賦形方法を提供することを目的とする。 The present disclosure has been made in view of such circumstances, and provides a pressurizing cooling mechanism, a molding jig, and a shaping method capable of continuously pressurizing and cooling the thermoplastic composite material while moving the thermoplastic composite material.

The gap is formed into the desired shape, and the first jig and the second jig move in the moving direction at the same speed as the moving speed of the thermoplastic composite material in the predetermined section.
　また、本開示の一態様に係る賦形方法は、所定方向に移動している加熱された熱可塑性複合材を成形治具によって加圧冷却して所望の形状かつ所定長さの熱可塑性複合材部品に賦形する賦形方法であって、前記成形治具は、前記所定長さとされている第１治具と第２治具とを有し、前記第１治具及び前記第２治具は、前記熱可塑性複合材の移動方向に沿った所定区間において前記移動方向と直交する方向にて前記熱可塑性複合材を挟み込んで対向するとともに、対向したときに形成される隙間が前記所望の形状とされ、前記第１治具及び前記第２治具が、前記所定区間において前記熱可塑性複合材の移動速度と同速度で前記移動方向に移動する加圧冷却工程を含む。 Further, in the shaping method according to one aspect of the present disclosure, the heated thermoplastic composite material moving in a predetermined direction is pressurized and cooled by a molding jig to obtain a thermoplastic composite material having a desired shape and a predetermined length. A shaping method for shaping a part, the molding jig has a first jig and a second jig having the predetermined length, and the first jig and the second jig.

　以下、本開示の一実施形態に係る加圧冷却機構、成形治具及び賦形方法について、図を参照して説明する。 Hereinafter, the pressure cooling mechanism, the molding jig, and the shaping method according to the embodiment of the present disclosure will be described with reference to the drawings.
　まず、加圧冷却機構１の概要について説明する。 First, the outline of the pressurized cooling mechanism 1 will be described.
　加圧冷却機構１は、フォーミング部６０にて加熱され所望の形状あるいは所望の形状に類似した形状となるように成形された熱可塑性複合材５０を、成形治具５によって加圧冷却することで所望の形状の完成部品（熱可塑性複合材部品５２）に賦形するものである。 The pressure cooling mechanism 1 pressurizes and cools the thermoplastic composite material 50, which is heated by the forming unit 60 and formed into a desired shape or a shape similar to the desired shape, by the molding jig 5. It is shaped into a finished part (thermoplastic composite part 52) having a desired shape.
　熱可塑性複合材５０は、例えば、繊維方向が一方向に揃えられた繊維基材及び繊維基材に含侵された樹脂によって構成される強化繊維シートの積層体とさる。繊維基材には、炭素繊維、ガラス繊維等の任意の繊維が用いられる。 The thermoplastic composite material 50 is, for example, a laminate of a fiber base material in which the fiber directions are aligned in one direction and a reinforcing fiber sheet composed of a resin impregnated in the fiber base material. Any fiber such as carbon fiber or glass fiber is used as the fiber base material.
　図１には、加圧冷却機構１を使用した熱可塑性複合材５０の加圧冷却における各工程が示されている。 FIG. 1 shows each step in pressurizing and cooling the thermoplastic composite material 50 using the pressurizing and cooling mechanism 1.
　加圧冷却機構１は、紙面左側から右側に向かって所定速度で移動する熱可塑性複合材５０を成形治具５によって加圧冷却する。 The pressure cooling mechanism 1 pressurizes and cools the thermoplastic composite material 50, which moves from the left side to the right side of the paper surface at a predetermined speed, by the molding jig 5.
　図１から図３に示すように、成形治具５は、熱可塑性複合材５０を挟み込んで対向する第１治具１０と第２治具２０とを有している。第１治具１０と第２治具２０とは、熱可塑性複合材５０の移動方向と直交する方向（同図の場合、上下方向）にて対向している。 As shown in FIGS. 1 to 3, the molding jig 5 has a first jig 10 and a second jig 20 facing each other with the thermoplastic composite material 50 sandwiched therein. The first jig 10 and the second jig 20 face each other in a direction orthogonal to the moving direction of the thermoplastic composite material 50 (in the case of the figure, the vertical direction).
　図２及び図３に示すように、熱可塑性複合材５０を挟み込んで加圧冷却するとき、第１治具１０と第２治具２０との間には熱可塑性複合材部品５２の形状（所望の形状）に対応した隙間４０が形成される。同図においては、横断面形状がハット型とされた長尺の熱可塑性複合材部品５２を賦形するために、同じハット型の横断面形状とされた隙間４０が形成されている。これによって、第１治具１０と第２治具２０とに挟み込まれた熱可塑性複合材５０が所望の形状の熱可塑性複合材部品５２に賦形される。 As shown in FIGS. 2 and 3, when the thermoplastic composite material 50 is sandwiched and pressurized and cooled, the shape of the thermoplastic composite material component 52 (desired) is formed between the first jig 10 and the second jig 20. A gap 40 corresponding to the shape of the above) is formed. In the figure, in order to shape a long thermoplastic composite component 52 having a hat-shaped cross-sectional shape, a gap 40 having the same hat-shaped cross-sectional shape is formed. As a result, the thermoplastic composite material 50 sandwiched between the first jig 10 and the second jig 20 is formed into the thermoplastic composite material component 52 having a desired shape.
　図１に示すように、第１治具１０及び第２治具２０は、熱可塑性複合材５０の移動方向において、所定の長さ寸法を有している。この寸法は、熱可塑性複合材部品５２（同図においてクロスハッチングされている部分）の長さ寸法に対応している。これによって、１つの成形治具５で１つの熱可塑性複合材部品５２を賦形することができる。 As shown in FIG. 1, the first jig 10 and the second jig 20 have a predetermined length dimension in the moving direction of the thermoplastic composite material 50. This dimension corresponds to the length dimension of the thermoplastic composite component 52 (the portion cross-hatched in the figure). Thereby, one thermoplastic composite material component 52 can be shaped by one molding jig 5.
　次に、加圧冷却機構１を使用した熱可塑性複合材５０の加圧冷却における各工程について説明する。 Next, each step in the pressure cooling of the thermoplastic composite material 50 using the pressure cooling mechanism 1 will be described.
　図１の工程Ａに示すように、熱可塑性複合材５０が進入するに十分な間隔を持って互いに離間された第１治具１０と第２治具２０との間に、所定速度で移動する熱可塑性複合材５０が進入する。このとき、熱可塑性複合材５０は、移動方向の上流側にあるフォーミング部６０にて加熱され所望の形状あるいは所望の形状に類似した形状となるように予め成形されている。 As shown in step A of FIG. 1, the thermoplastic composite material 50 moves at a predetermined speed between the first jig 10 and the second jig 20 separated from each other with a sufficient distance for entering. The thermoplastic composite material 50 enters. At this time, the thermoplastic composite material 50 is heated by the forming portion 60 on the upstream side in the moving direction and is preformed so as to have a desired shape or a shape similar to the desired shape.
　図１の工程Ｂに示すように、熱可塑性複合材５０が第１治具１０及び第２治具２０の長さ寸法以上進入したところで、第１治具１０と第２治具２０とは互いに接近するように移動して熱可塑性複合材５０を挟み込む。これによって、熱可塑性複合材５０が加圧されるとともに冷却が開始される。 As shown in step B of FIG. 1, when the thermoplastic composite material 50 has entered the length dimension of the first jig 10 and the second jig 20 or more, the first jig 10 and the second jig 20 come into contact with each other. The thermoplastic composite material 50 is sandwiched by moving so as to approach each other. As a result, the thermoplastic composite material 50 is pressurized and cooling is started.
　第１治具１０及び第２治具２０は、耐熱性に優れ熱容量の大きい材料（例えばステンレス等の金属）とされることが好ましい。これによって、加熱された熱可塑性複合材５０を効率的に冷却することができるからである。 The first jig 10 and the second jig 20 are preferably made of a material having excellent heat resistance and a large heat capacity (for example, a metal such as stainless steel). This is because the heated thermoplastic composite material 50 can be efficiently cooled.
　また、第１治具１０及び第２治具２０を冷却する冷却機構（図示せず）を備えてもよく、この場合、より効率的に熱可塑性複合材５０を冷却することができる。 Further, a cooling mechanism (not shown) for cooling the first jig 10 and the second jig 20 may be provided, and in this case, the thermoplastic composite material 50 can be cooled more efficiently.
　図１の工程Ｃに示すように、第１治具１０及び第２治具２０は、熱可塑性複合材５０を挟み込んだ状態（すなわち加圧冷却した状態）で、熱可塑性複合材５０の移動と同方向に、かつ、同速度で所定区間だけ移動する（加圧冷却工程）。これによって、所定区間において熱可塑性複合材５０を移動させたまま連続的に加圧冷却することができる。 As shown in step C of FIG. 1, the first jig 10 and the second jig 20 move the thermoplastic composite material 50 in a state of sandwiching the thermoplastic composite material 50 (that is, in a pressure-cooled state). It moves in the same direction and at the same speed for a predetermined section (pressurized cooling step). As a result, the thermoplastic composite material 50 can be continuously pressurized and cooled while being moved in a predetermined section.
　図１の工程Ｄに示すように、熱可塑性複合材５０が十分に加圧冷却されたとき、第１治具１０と第２治具２０とは互いに離間するように移動する。これによって、加圧冷却が終了して、熱可塑性複合材５０が所望の形状かつ所定の長さ寸法の熱可塑性複合材部品５２に賦形されることとなる。 As shown in step D of FIG. 1, when the thermoplastic composite material 50 is sufficiently pressurized and cooled, the first jig 10 and the second jig 20 move so as to be separated from each other. As a result, the pressurized cooling is completed, and the thermoplastic composite material 50 is formed into the thermoplastic composite material component 52 having a desired shape and a predetermined length dimension.
　第１治具１０と第２治具２０とは、互いに離間した後、熱可塑性複合材５０の移動方向とは反対方向に移動して図１の工程Ａに示された位置に戻る。工程Ａに示された位置に戻っている間に、熱可塑性複合材５０によって昇温された第１治具１０及び第２治具２０は冷却される。
　なお、第１治具１０と第２治具２０とは、必ずしも図１の工程Ａに示された位置に戻らなくてもよく、工程Ａに示された位置とは異なる位置に戻ってもよい。 After the first jig 10 and the second jig 20 are separated from each other, they move in the direction opposite to the moving direction of the thermoplastic composite material 50 and return to the position shown in step A of FIG. While returning to the position shown in step A, the first jig 10 and the second jig 20 heated by the thermoplastic composite material 50 are cooled.
The first jig 10 and the second jig 20 do not necessarily have to return to the positions shown in step A of FIG. 1, and may return to positions different from the positions shown in step A. ..
　第１治具１０と第２治具２０とが互いに接近するタイミング、すなわち加圧冷却が開示されるタイミング、及び、第１治具１０と第２治具２０とが互いに離間するタイミング、すなわち加圧冷却が完了するタイミングは、図示しない制御部１００によって例えば次のように制御される。 The timing at which the first jig 10 and the second jig 20 approach each other, that is, the timing at which pressure cooling is disclosed, and the timing at which the first jig 10 and the second jig 20 separate from each other, that is, addition. The timing at which pressure cooling is completed is controlled by a control unit 100 (not shown), for example, as follows.
　制御部１００は、加圧冷却機構１の仕様、熱可塑性複合材５０及び熱可塑性複合材部品５２の形状、物性その他の外的要因に応じて予め決定された加圧冷却時間に基づいて加圧冷却を制御する。 The control unit 100 pressurizes based on the pressurization / cooling time determined in advance according to the specifications of the pressurization / cooling mechanism 1, the shapes of the thermoplastic composite material 50 and the thermoplastic composite material component 52, physical properties and other external factors. Control cooling.
　また、第１治具１０と第２治具２０とに挟み込まれた熱可塑性複合材５０の温度を測定可能なセンサを設け、制御部１００は、挟み込まれた熱可塑性複合材５０の温度が予め設定された温度まで下がったときに加圧冷却を完了してもよい。 Further, a sensor capable of measuring the temperature of the thermoplastic composite material 50 sandwiched between the first jig 10 and the second jig 20 is provided, and the control unit 100 sets the temperature of the sandwiched thermoplastic composite material 50 in advance. Pressurized cooling may be completed when the temperature drops to the set temperature.
　また、時間に基づいた加圧冷却の制御と温度に基づいた加圧冷却の制御との組合せであってもよい。 Further, it may be a combination of time-based pressurization / cooling control and temperature-based pressurization / cooling control.
　制御部１００は、例えば、ＣＰＵ（Central　Processing　Unit）、ＲＡＭ（Random　Access　Memory）、ＲＯＭ（Read　Only　Memory）、及びコンピュータ読み取り可能な記憶媒体等から構成されている。そして、各種機能を実現するための一連の処理は、一例として、プログラムの形式で記憶媒体等に記憶されており、このプログラムをＣＰＵがＲＡＭ等に読み出して、情報の加工・演算処理を実行することにより、各種機能が実現される。なお、プログラムは、ＲＯＭやその他の記憶媒体に予めインストールしておく形態や、コンピュータ読み取り可能な記憶媒体に記憶された状態で提供される形態、有線又は無線による通信手段を介して配信される形態等が適用されてもよい。コンピュータ読み取り可能な記憶媒体とは、磁気ディスク、光磁気ディスク、ＣＤ－ＲＯＭ、ＤＶＤ－ＲＯＭ、半導体メモリ等である。 The control unit 100 is composed of, for example, a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), a computer-readable storage medium, and the like. Then, as an example, a series of processes for realizing various functions are stored in a storage medium or the like in the form of a program, and the CPU reads this program into a RAM or the like to execute information processing / arithmetic processing. As a result, various functions are realized. The program is installed in a ROM or other storage medium in advance, is provided in a state of being stored in a computer-readable storage medium, or is distributed via a wired or wireless communication means. Etc. may be applied. Computer-readable storage media include magnetic disks, magneto-optical disks, CD-ROMs, DVD-ROMs, semiconductor memories, and the like.
　図１の工程Ａから工程Ｄを繰り返すことで、熱可塑性複合材５０を移動させたまま連続的に加圧冷却して熱可塑性複合材部品５２を連続的に賦形する。 By repeating steps A to D in FIG. 1, the thermoplastic composite material 50 is continuously pressurized and cooled while being moved, and the thermoplastic composite material component 52 is continuously shaped.
　なお、第１治具１０と第２治具２０とを有する成形治具５は複数あってもよい。この場合、複数の成形治具５が交互に熱可塑性複合材５０を冷却することとなるので、一の成形治具５の直後（移動方向において下流側の直後）に他の成形治具５を配置することができる。これによって、移動する熱可塑性複合材５０を隙間なく加圧冷却することができる。また、図１の工程Ａに示された位置まで戻るための時間を確保できるので、熱可塑性複合材５０によって昇温した第１治具１０及び第２治具２０に対して十分な冷却時間を確保することができる。 Note that there may be a plurality of molding jigs 5 having the first jig 10 and the second jig 20. In this case, since the plurality of molding jigs 5 alternately cool the thermoplastic composite material 50, the other molding jig 5 is immediately after one molding jig 5 (immediately after the downstream side in the moving direction). Can be placed. As a result, the moving thermoplastic composite material 50 can be pressurized and cooled without gaps. Further, since the time for returning to the position shown in the step A of FIG. 1 can be secured, a sufficient cooling time is provided for the first jig 10 and the second jig 20 which have been heated by the thermoplastic composite material 50. Can be secured.
　また、第１治具１０及び第２治具２０は、次のよう構成されてもよい。
　図４及び図５に示すように、第１治具１０を例にして説明すると、第１治具１０は、ベースツール部１２と、ベースツール部１２に取り付けられた成形型部１４とを有している。 Further, the first jig 10 and the second jig 20 may be configured as follows.
As shown in FIGS. 4 and 5, the first jig 10 will be described as an example. The first jig 10 has a base tool portion 12 and a molding mold portion 14 attached to the base tool portion 12. doing.
　ベースツール部１２は、所定の長さ寸法とされた部材とされ、成形型部１４を保持することができる。ベースツール部１２は、熱可塑性複合材部品５２の形状に依らず、どのような熱可塑性複合材部品５２の形状であっても共通の部品とされる。 The base tool portion 12 is a member having a predetermined length dimension, and can hold the molding mold portion 14. The base tool portion 12 is a common component regardless of the shape of the thermoplastic composite material component 52, regardless of the shape of the thermoplastic composite material component 52.
　成形型部１４は、実質的に成形型として作用する部分であって、賦形したい熱可塑性複合材部品５２の形状に依ってその形状が異なる（図５参照）。詳細には、成形型部１４は、賦形したい熱可塑性複合材部品５２の形状に依って、相手方の成形部材とともに熱可塑性複合材５０を挟み込んで対向したときに形成される隙間４０の形状が異なるように構成される。 The molding die portion 14 is a portion that substantially acts as a molding die, and its shape differs depending on the shape of the thermoplastic composite material part 52 to be shaped (see FIG. 5). Specifically, the molding die portion 14 has a shape of a gap 40 formed when the thermoplastic composite material 50 is sandwiched and opposed to each other together with the molding member of the other party, depending on the shape of the thermoplastic composite material component 52 to be shaped. Configured differently.
　成形型部１４は、形状の異なる複数種類が予め用意されており、それらを適宜交換することによって同一の加圧冷却機構１を用いて効率的に複数種類の熱可塑性複合材部品５２を賦形することができる。また、同種類の成形型部１４を複数ストックしておくことで、一の成形型部１４を使用している間に他の成形型部１４のメンテナンスを実施することができる。 A plurality of types of molding mold portions 14 having different shapes are prepared in advance, and by appropriately exchanging them, a plurality of types of thermoplastic composite material parts 52 can be efficiently shaped by using the same pressure cooling mechanism 1. can do. Further, by stocking a plurality of molding mold portions 14 of the same type, maintenance of the other molding mold portions 14 can be performed while one molding mold portion 14 is being used.
　このように、第１治具１０をベースツール部１２と成形型部１４とに分けて構成することによって、第１治具１０のメンテナンス性や熱可塑性複合材部品５２の生産性を向上させることができる。 In this way, by separately configuring the first jig 10 into the base tool portion 12 and the molding mold portion 14, the maintainability of the first jig 10 and the productivity of the thermoplastic composite material component 52 can be improved. Can be done.
　なお、図６及び図７に示すように、成形型部１４は、ベースツール部１２の長さ方向（図において紙面左右方向）に沿って複数のブロックに分割されてもよい。このとき、長さ方向は、熱可塑性複合材５０の移動方向に沿う。この場合、成形型部１４は次のように使用される。 As shown in FIGS. 6 and 7, the molding die portion 14 may be divided into a plurality of blocks along the length direction of the base tool portion 12 (the left-right direction on the paper surface in the drawing). At this time, the length direction is along the moving direction of the thermoplastic composite material 50. In this case, the molding die portion 14 is used as follows.
　例えば、成形型部１４を、図４の点線で示された縦断面形状から図５の点線で示された縦断面形状に変更したい場合、図６及び図７に示すように、断面形状に変更が生じた部分のブロックのみを交換することで断面形状の変更が可能となる。これによって、簡便に断面形状の変更をすることができる。また、ブロックの数によって長さ方向における隙間４０の寸法を容易に変更することができる。 For example, when it is desired to change the molding die portion 14 from the vertical cross-sectional shape shown by the dotted line in FIG. 4 to the vertical cross-sectional shape shown by the dotted line in FIG. 5, change to the cross-sectional shape as shown in FIGS. 6 and 7. It is possible to change the cross-sectional shape by exchanging only the block of the part where the above occurs. Thereby, the cross-sectional shape can be easily changed. Further, the dimension of the gap 40 in the length direction can be easily changed depending on the number of blocks.
　また、仮に成形型部１４が部分的に破損した場合であっても、ブロックの部分的な交換によって成形型部１４を修復することができる。 Further, even if the molding die portion 14 is partially damaged, the molding die portion 14 can be repaired by partially replacing the block.
　以上、第１治具１０の成形型部１４について説明したが、第２治具２０の成形型部についても同様の構成とされる。 Although the molding mold portion 14 of the first jig 10 has been described above, the molding mold portion of the second jig 20 has the same configuration.
　本実施形態によれば、以下の効果を奏する。
　加圧冷却機構１によれば、成形治具５は、熱可塑性複合材部品５２の所定長さとされている第１治具１０と第２治具２０とを有し、第１治具１０及び第２治具２０は、熱可塑性複合材５０の移動方向に沿った所定区間において移動方向と直交する方向にて熱可塑性複合材５０を挟み込んで対向するとともに、対向したときに形成される隙間４０が所望の形状とされている。これによって、所定区間にて第１治具１０及び第２治具２０に挟み込まれた熱可塑性複合材５０は、形成された隙間４０内で加圧冷却されて所望の形状に賦形され熱可塑性複合材部品５２となる。 According to this embodiment, the following effects are obtained.
According to the pressure cooling mechanism 1, the forming jig 5 has a first jig 10 and a second jig 20 having a predetermined length of the thermoplastic composite material component 52, and the first jig 10 and the second jig 20 The second jig 20 faces the thermoplastic composite material 50 with the thermoplastic composite material 50 sandwiched in a direction orthogonal to the moving direction in a predetermined section along the moving direction of the thermoplastic composite material 50, and a gap 40 formed when the second jig 20 faces the moving direction. Is the desired shape. As a result, the thermoplastic composite material 50 sandwiched between the first jig 10 and the second jig 20 in a predetermined section is pressurized and cooled in the formed gap 40 to be shaped into a desired shape and is thermoplastic. It becomes a composite material component 52.
　また、所定区間における第１治具１０及び第２治具２０は、熱可塑性複合材５０と同速度で移動方向に移動する。これによって、熱可塑性複合材５０を移動させたまま連続的に加圧冷却することができる。 Further, the first jig 10 and the second jig 20 in the predetermined section move in the moving direction at the same speed as the thermoplastic composite material 50. As a result, the thermoplastic composite material 50 can be continuously pressurized and cooled while being moved.
　第１治具１０及び第２治具２０を冷却する冷却機構を備えている場合、第１治具１０及び第２治具２０が強制的に冷却され、より効率的に加熱された熱可塑性複合材５０を加圧冷却することができる。 When a cooling mechanism for cooling the first jig 10 and the second jig 20 is provided, the first jig 10 and the second jig 20 are forcibly cooled, and the thermoplastic composite is heated more efficiently.
