" However, according to the film transport mechanism of Patent Document 1, the tension of the transport film is always stable and cannot be controlled to a constant value, and the transport film becomes slack at the time of starting / stopping the constant-size feed. Sometimes.

また、フィルムの搬送中に連続して変化するロールの径は、フィルムの搬送速度とロールの回転数に基づいて演算して求め、サーボモータの出力トルクに反映されることは特許文献２に記載がある。しかしながら、新規にロールを設置してフィルムの搬送を開始する際等には、ロールの径を実測して入力する必要があり、手間を要するものである。
特許第３６４６０６８号公報（段落００４５） 特公平２−２０５４７号公報 Moreover, it is described in Patent Document 2 that the diameter of the roll that continuously changes during film conveyance is calculated based on the film conveyance speed and the number of rotations of the roll, and is reflected in the output torque of the servo motor. There is. However, when a roll is newly installed and film conveyance is started, it is necessary to measure and input the roll diameter, which is troublesome.

図面に基づいて、本発明の実施の形態を詳細に説明する。図１は本発明の搬送フィルムの搬送機構の制御方法を実施する搬送フィルムの搬送機構を加工装置とともに示す概要図であり、図２は搬送フィルムの張力の制御状態を示す説明図であり、図３は巻き取りロール及び巻き出しロールの径を自動的に測定する工程を示す流れ図である。   Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic view showing a transport film transport mechanism for carrying out the transport film transport mechanism control method of the present invention together with a processing apparatus, and FIG. 2 is an explanatory view showing a tension control state of the transport film. 3 is a flowchart showing a process of automatically measuring the diameters of the winding roll and the unwinding roll.

図１において、真空積層装置１と平坦化プレス２は加工装置１６を構成し、加工装置１６以外に記載されたものは、連続する搬送フィルム３，４を加工装置１６へ間欠的に搬入、搬出する搬送フィルム３，４の搬送機構２０である。この実施の形態では、搬送フィルム３，４が加工装置１６へ上下平行となって搬入、搬出される例を示している。図中の矢印は搬送フィルムの搬送方向である。搬送フィルム３又は搬送フィルム４を含むそれぞれの搬送フィルムの搬送機構はそれぞれ同一の構成を有し、必要に応じて、それらの何れか一方又は双方が設けられる。   In FIG. 1, the vacuum laminating apparatus 1 and the flattening press 2 constitute a processing apparatus 16, and those described other than the processing apparatus 16 intermittently carry in and out the continuous transport films 3 and 4 to and from the processing apparatus 16. It is the conveyance mechanism 20 of the conveyance films 3 and 4 to perform. In this embodiment, an example is shown in which the transport films 3 and 4 are carried into and out of the processing device 16 in parallel in the vertical direction. The arrow in the figure is the transport direction of the transport film. The conveyance mechanism of each conveyance film including the conveyance film 3 or the conveyance film 4 has the same structure, and either one or both of them is provided as necessary.

真空積層装置１は、上下に開閉する盤とそれらの間に設けた加圧膜とで真空チャンバを形成し、その真空チャンバ内で搬送フィルム３，４に挟持された成形材料を加熱・加圧して、成形材料を積層成形するものである。平坦化プレス２は、真空積層装置１で成形材料を積層成形して得た中間成形品をさらに加熱又は冷却して、中間成形品の表面を平坦に成形して成形品となすものである。なお、加工装置１６として真空積層装置１と平坦化プレス２を例示したが、加工装置はこれらのいずれか一方のみで構成するものであってもよいし、搬送フィルムを必要とし他の機能を備えたような加工装置であってもよい。   The vacuum laminating apparatus 1 forms a vacuum chamber by a board that opens and closes up and down and a pressure film provided therebetween, and heats and pressurizes the molding material sandwiched between the transport films 3 and 4 in the vacuum chamber. Thus, the molding material is laminated and molded. The flattening press 2 further heats or cools an intermediate molded product obtained by laminating molding materials with the vacuum laminating apparatus 1 to form the surface of the intermediate molded product flat to form a molded product. In addition, although the vacuum laminating apparatus 1 and the flattening press 2 were illustrated as the processing apparatus 16, a processing apparatus may be comprised only in any one of these, and a conveyance film is required and is equipped with another function. Such a processing apparatus may be used.

搬送フィルム３，４は、成形材料、中間成形品及び成形品を挟持して搬送する。真空積層装置１の搬入側で搬送フィルム４上に配置された成形材料は、搬送フィルム３，４の搬送に伴って真空積層装置１のチャンバへ搬入されるとともに、真空積層装置１で積層された中間成形品は真空積層装置１から搬出されそのまま平坦化プレス２へ搬入される。さらに、平坦化プレス２で成形された成形品は、平坦化プレス２の搬出側へ搬出・搬送される。このとき、搬送フィルム３，４は、成形材料の積層成形時に成形材料から滲出する樹脂から加圧膜等を保護する離型フィルムとしても作用する。このように、搬送フィルム３，４は、真空積層装置１と平坦化プレス２との中心距離に相当する距離を成形サイクル時間に基づいて間欠的に定寸移動するのである。   The transport films 3 and 4 sandwich and transport the molding material, the intermediate molded product, and the molded product. The molding material arranged on the conveyance film 4 on the carry-in side of the vacuum laminating apparatus 1 is carried into the chamber of the vacuum laminating apparatus 1 along with the conveyance of the conveying films 3 and 4 and is laminated by the vacuum laminating apparatus 1. The intermediate molded product is unloaded from the vacuum laminating apparatus 1 and is loaded into the flattening press 2 as it is. Further, the molded product formed by the flattening press 2 is carried out and conveyed to the carry-out side of the flattening press 2. At this time, the transport films 3 and 4 also function as a release film that protects the pressure film and the like from the resin that exudes from the molding material when the molding material is laminated. As described above, the transport films 3 and 4 are intermittently moved by a fixed distance based on the molding cycle time by a distance corresponding to the center distance between the vacuum laminating apparatus 1 and the flattening press 2.

このとき、搬送フィルム３，４は、加工装置１６の搬入側と搬出側とで相互に反対方向に牽引して張力が付与されている。そのようにしないと、搬送フィルム３，４は加工装置１６内で垂下して加圧面に部分的に接触し、成形状態が変化するために、均一で良好な成形品を成形することが出来ない。特に、搬送フィルム３，４の間欠移動のための起動停止時には張力の制御が不安定となって弛みが生じやすい。そこで、発明者らは、搬送フィルム３，４の張力が常時安定して定値に制御可能な搬送フィルムの搬送機構の制御方法を発明したのである。   At this time, the transport films 3 and 4 are pulled and tensioned in the opposite directions on the carry-in side and the carry-out side of the processing device 16. Otherwise, the transport films 3 and 4 hang down in the processing device 16 and partially contact the pressure surface, and the molding state changes, so a uniform and good molded product cannot be molded. . In particular, when starting and stopping for intermittent movement of the transport films 3 and 4, tension control becomes unstable and slack is likely to occur. Therefore, the inventors have invented a method for controlling the transport mechanism of the transport film that allows the tension of the transport films 3 and 4 to be always stable and controlled to a constant value.

搬送フィルム３，４の搬送機構２０は、搬送フィルム３用の上側搬送機構２３と、搬送フィルム４用の下側搬送機構２４とからなり、両者２３，２４の機構は同一である。そのため、搬送フィルム４用の下側搬送機構２４についてのみ説明することとする。巻き出しロール６は、加工装置１６の搬送フィルム搬入側に設けられ、筒芯に所定量の搬送フィルム４が巻回されたものである。巻き出しロール６には、サーボモータ（巻き出し用サーボモータ）７で駆動される巻き出し軸５が該サーボモータ７の回転力を確実に伝達するように嵌挿されている。巻き出しロール６から導出された搬送フィルム４は多くのローラで方向を変換されて真空積層装置１に導入される。平坦化プレス２から導出された搬送フィルム４は多くのローラとニップロール１４を介して巻き取りロール９に巻回される。巻き取りロール９は、加工装置１６の搬送フィルム搬出側に設けられ、筒芯に所定量の搬送フィルム４を巻回するものである。巻き取りロール９には、サーボモータ（巻き取り用サーボモータ）１０で駆動される巻き取り軸８が該サーボモータ１０の回転力を確実に伝達するように嵌挿されている。ニップロール１４は、サーボモータ（ニップロール用サーボモータ）１５で駆動される下ロール１３と、下ロール１３に対してエアシリンダ１１により接離自在に移動可能な上ロール１２とからなる。上ロール１２と下ロール１３の間に挟装した搬送フィルム４はエアシリンダ１１で押圧されつつサーボモータ１５により搬送される。   The transport mechanism 20 for the transport films 3 and 4 includes an upper transport mechanism 23 for the transport film 3 and a lower transport mechanism 24 for the transport film 4, and the mechanisms of both the transport films 23 and 24 are the same. Therefore, only the lower transport mechanism 24 for the transport film 4 will be described. The unwinding roll 6 is provided on the conveying film carry-in side of the processing device 16 and has a predetermined amount of the conveying film 4 wound around a cylindrical core. An unwinding shaft 5 driven by a servomotor (unwinding servomotor) 7 is fitted into the unwinding roll 6 so as to reliably transmit the rotational force of the servomotor 7. The direction of the transport film 4 led out from the unwinding roll 6 is changed by many rollers and introduced into the vacuum laminating apparatus 1. The transport film 4 led out from the flattening press 2 is wound around a take-up roll 9 through many rollers and a nip roll 14. The take-up roll 9 is provided on the conveying film carry-out side of the processing device 16 and winds a predetermined amount of the conveying film 4 around the cylinder core. A winding shaft 8 driven by a servo motor (winding servo motor) 10 is fitted into the winding roll 9 so as to reliably transmit the rotational force of the servo motor 10. The nip roll 14 includes a lower roll 13 that is driven by a servo motor (a nip roll servo motor) 15 and an upper roll 12 that can be moved to and away from the lower roll 13 by an air cylinder 11. The transport film 4 sandwiched between the upper roll 12 and the lower roll 13 is transported by the servo motor 15 while being pressed by the air cylinder 11.

搬送フィルム４が搬送中であろうと停止中であろうと、搬送フィルム４には常時一定の張力が与えられることが加工装置１６での成形上好ましい。そのため、巻き出しロール６と巻き取りロール９による搬送フィルム４の牽引力をそれぞれ反対方向の同値とし平衡するようにした状態で、ニップロール１４によって搬送フィルム４を搬送するように構成したのである。ここでは、両牽引力（張力）が同値でありその演算・制御方法も同一であるから、巻き取りロール９についてのみ演算・制御方法を説明する。図１中、符号１７は制御装置であり公知のＰＬＣ、マイコン等から構成される。   Whether the transport film 4 is being transported or stopped, it is preferable in terms of molding with the processing device 16 that a constant tension is always applied to the transport film 4. Therefore, the transport film 4 is transported by the nip roll 14 in a state where the pulling force of the transport film 4 by the unwinding roll 6 and the take-up roll 9 is the same value in the opposite directions and balanced. Here, since both traction forces (tensions) have the same value and the same calculation / control method, only the winding / rolling roll 9 will be described. In FIG. 1, reference numeral 17 denotes a control device, which includes a known PLC, microcomputer, and the like.

図２に示すように、搬送フィルム４の張力をＦとする。張力Ｆを発生させるため巻き取りロール９を駆動するサーボモータ１０の出力トルクＴ1は、巻き取りロール９の直径をＤとすると、式〈１〉により表される。 As shown in FIG. 2, let the tension of the transport film 4 be F. The output torque T 1 of the servo motor 10 that drives the take-up roll 9 to generate the tension F is expressed by the formula <1>, where D is the diameter of the take-up roll 9.

When the friction coefficient is σ and the mechanical efficiency is η, it is expressed by the formula <2>. The general value of σ is 0.01 to 0.05, and the general value of η is 0.8 to 0.85.

巻き取りロール９の慣性に相当する慣性補償トルクＴ3は、サーボモータ１０の慣性モーメントをＭ1、巻き取りロール９の慣性モーメントをＭ2、巻き取りロール９（サーボモータ１０）の回転速度をＮ、ニップロール１４の加減速時間をＡとすると、式〈３〉により表される。そして、式〈４〉の関係がある。また、フィルム４の搬送速度をＶとすると、式〈５〉の関係がある。 The inertia compensation torque T 3 corresponding to the inertia of the winding roll 9 is M 1 for the moment of inertia of the servo motor 10, M 2 for the moment of inertia of the winding roll 9, and the rotational speed of the winding roll 9 (servo motor 10). When N is the acceleration / deceleration time of the nip roll 14, A is expressed by the formula <3>. And there exists a relationship of Formula <4>. Further, when the conveyance speed of the film 4 is V, there is a relationship of the formula <5>.

ところで、巻き取りロール９における軸方向断面の単位面積あたりの搬送フィルム４の重量Ｗ1は、巻き出し軸５に装着する新しい巻き出しロール６としての巻回された搬送フィルム４の重量をＷf、その巻回搬送フィルム４の直径をＤm、巻き取り軸５であってフィルム４の筒芯を含む直径をＤ1とすると、式〈６〉である。そして、張力Ｆ制御中の巻き取りロール９における軸方向の搬送フィルム部断面積Ｓは、式〈７〉であるから、巻き取りロール９の全重量Ｗは、巻き取り軸の重量をＷ2とすると、式〈８〉となる。 Incidentally, the weight W 1 of the conveying film 4 per unit area of the axial section of the take-up roll 9, a winding weight of conveying film 4 which is wound as a roll 6 unwinding new mounted to the feeding shaft 5 W f When the diameter of the wound transport film 4 is D m and the diameter of the winding shaft 5 including the cylindrical core of the film 4 is D 1 , the formula <6> is established. The conveying film cross-sectional area S of the axial direction of the take-up roll 9 in the tension F control, since an expression <7>, the total weight W of the take-up roll 9, and the weight of the winding shaft W 2 Then, Expression <8> is obtained.

したがって、巻き取りロール９の直径を計測しＤとして、サーボモータ１０を制御する制御装置１７に入力し、また、Ｄ1、Ｄ2、Ｄm、Ｍ1、Ｍ2、Ａ、Ｖ、Ｗ2、Ｗf、σ及びηを搬送フィルムの搬送機構における固有の値又は設定値として制御装置１７に入力する。そして、制御装置１７は、式〈１〉、式〈２〉及び式〈３〉に基づいてトルク値を演算しサーボモータ１０へ出力する。搬送開始後、制御装置１７は、式〈５〉に基づいてサーボモータ１０のエンコーダの検出値から求めたサーボモータ１０の回転速度Ｎと、設定された搬送フィルム４の搬送速度Ｖとから、変化するＤの値を演算して求める。また、式〈６〉及び式〈７〉から式〈８〉に基づいてＷを求め、式〈４〉によりＭ2を求める。このようにして求めたＴ1、Ｔ2、及びＴ3に基づいて、制御装置１７は、トルク値を、起動から定速に向けて加速搬送中はＴ1＋Ｔ2＋Ｔ3とし、定速搬送中はＴ1＋Ｔ2とし、定速から停止に向けて減速搬送中はＴ1＋Ｔ2−Ｔ3として演算し、それらに応じた電流をサーボモータ１０へ出力・供給する。なお、巻き出しロール６を駆動するサーボモータ７のトルク値については、巻き出しロール６のＴ1は上記の巻き取りロール９のＴ1と同様に巻き出しロール６に応じた値として算出され、巻き取りロール９のＴ１とは方向が逆であり、巻き出しロール６のＴ2及びＴ3は上記の巻き取りロール９のＴ2及びＴ3と同様に巻き出しロール６に応じた値として算出し、その方向は巻き取りロール９のＴ2及びＴ3と同じ方向である。 Therefore, the diameter of the take-up roll 9 is measured and input as D to the control device 17 that controls the servo motor 10, and D 1 , D 2 , D m , M 1 , M 2 , A, V, W 2. , W f , σ, and η are input to the control device 17 as specific values or set values in the transport mechanism of the transport film. Then, the control device 17 calculates a torque value based on the formulas <1>, <2>, and <3> and outputs the torque value to the servo motor 10. After the start of conveyance, the control device 17 changes from the rotation speed N of the servo motor 10 obtained from the detected value of the encoder of the servo motor 10 based on the formula <5> and the set conveyance speed V of the conveyance film 4. The value of D to be calculated is calculated. Also, determine the W based on the equation <8> from the equation <6> and formula <7>, obtaining the M 2 by formula <4>. Based on T 1 , T 2 , and T 3 obtained in this way, the control device 17 sets the torque value to T 1 + T 2 + T 3 during the accelerated transfer from the start to the constant speed, and the constant speed transfer. and T 1 + T 2 is in, during deceleration conveyed to stop the constant speed is calculated as T 1 + T 2 -T 3, the output-supplies a current corresponding to those to the servo motor 10. Note that the torque value of the servo motor 7 for driving the roll 6 unwinding, T 1 of the supply roll 6 is calculated as a value corresponding to the roll 6 unrolled similarly to T 1 of the above-described take-up roll 9, a contrary direction to the T1 of the winding roll 9, T 2 and T 3 of the supply roll 6 is calculated as a value corresponding to the roll 6 unrolled similarly to T 2 and T 3 of the above take-up roll 9 The direction is the same as T 2 and T 3 of the winding roll 9.

ところで、巻き取りロール９（巻き出しロール６）の直径Ｄは、搬送フィルムの補充や交換のため搬送機構のロールに新たに装着した後の起動時には、式〈５〉から理解されるように、巻き取りロール９の回転速度が不明であるため、求められない。そこで、搬送フィルムの搬送機構の起動のために、Ｄ値を制御装置１７に設定入力する必要がある。しかしながら、巻き取りロール９（巻き出しロール６）の直径を計測することは容易ではなく、また、計測誤差も問題となる。そのため、下記に示すようなロールの外径自動測定方法を実施するのである。   By the way, the diameter D of the take-up roll 9 (unwinding roll 6) can be understood from the formula <5> at the time of start-up after being newly attached to the roll of the transport mechanism for replenishment or replacement of the transport film. Since the rotational speed of the winding roll 9 is unknown, it cannot be obtained. Therefore, it is necessary to set and input the D value to the control device 17 in order to activate the transport mechanism for the transport film. However, it is not easy to measure the diameter of the winding roll 9 (unwinding roll 6), and a measurement error also becomes a problem. Therefore, the roll outer diameter automatic measuring method as shown below is carried out.

図３の流れ図に示すように、加工装置１６で成形しない状態でスタートする（Ｓ１０１）。ニップロール１４の上ロール１２をエアシリンダ１１で上昇させ、ニップロール１４による搬送フィルム４の搬送駆動を解除する（Ｓ１０２）。サーボモータ７を最少トルクで、サーボモータ１０を最大トルクで制御して（Ｓ１０３）、搬送フィルム４を巻き出しロール６から巻き取りロール９へ搬送させる。サーボモータ７，１０の回転速度が零か否かを比較演算して判断する（Ｓ１０４）。サーボモータ７，１０の回転速度が零ではなかったとき、サーボモータ１０のトルクを１％減少させる（Ｓ１０５）。Ｓ１０５のステップは、Ｓ１０４のステップでサーボモータ７，１０の回転速度が零になるまで繰返される。サーボモータ７，１０の回転速度が零になったら、ニップロール１４の上ロール１２をエアシリンダ１１で下降させ、ニップロール１４による搬送フィルム４の搬送駆動が可能な状態にする（Ｓ１０６）。サーボモータ１５でニップロール１４を駆動して、搬送フィルム４を所定速度で搬送移動させる（Ｓ１０７）。そのときの搬送フィルム４の搬送速度Ｖとサーボモータ７，１０の回転速度Ｎから式〈５〉に基づいて巻き出しロール６と巻き取りロール９の直径Ｄを求める（Ｓ１０８）。そして、搬送フィルム４の搬送中には、制御装置１７の制御スキャン毎に式〈５〉の演算を実行して直径Ｄの値を更新する。   As shown in the flowchart of FIG. 3, the processing apparatus 16 starts without being molded (S101). The upper roll 12 of the nip roll 14 is raised by the air cylinder 11, and the conveyance drive of the conveyance film 4 by the nip roll 14 is released (S102). The servo motor 7 is controlled by the minimum torque and the servo motor 10 is controlled by the maximum torque (S103), and the transport film 4 is transported from the unwinding roll 6 to the winding roll 9. A comparison is made to determine whether or not the rotation speeds of the servo motors 7 and 10 are zero (S104). When the rotational speeds of the servo motors 7 and 10 are not zero, the torque of the servo motor 10 is reduced by 1% (S105). The step of S105 is repeated until the rotational speed of the servomotors 7 and 10 becomes zero in the step of S104. When the rotation speeds of the servo motors 7 and 10 become zero, the upper roll 12 of the nip roll 14 is lowered by the air cylinder 11 so that the transport drive of the transport film 4 by the nip roll 14 is possible (S106). The nip roll 14 is driven by the servo motor 15, and the transport film 4 is transported and moved at a predetermined speed (S107). The diameter D of the unwinding roll 6 and the winding roll 9 is obtained from the transport speed V of the transport film 4 and the rotational speed N of the servomotors 7 and 10 based on the formula <5> (S108). Then, during the conveyance of the conveyance film 4, the value of the diameter D is updated by executing the calculation of the formula <5> for each control scan of the control device 17.

このように、巻き出しロール６の直径Ｄの最新値は常時演算され求められているので、巻き出しロール６の直径Ｄが巻き取り軸の直径Ｄ1に所定値を加えた値より小さくなったときに、制御装置１７は搬送フィルム４の不足を予告する警報を出力することができる。この警報により、作業者は新しい搬送フィルムが巻回された巻き出しロール６を予め用意することができ、成形作業が中断することがなくなり、生産効率の向上に貢献する。 Thus, since the latest value of the diameter D of the supply roll 6 being sought is calculated at all times, it becomes less than the diameter D of the supply roll 6 by adding a predetermined value to the diameter D 1 of the winding shaft value Sometimes, the control device 17 can output an alarm for notifying the shortage of the transport film 4. By this warning, the operator can prepare in advance the unwinding roll 6 around which a new transport film is wound, so that the forming operation is not interrupted, which contributes to the improvement of production efficiency.

また、成形サイクルが度重なって進行し巻き出しロール６の搬送フィルム４が導出して全てなくなったときには、巻き出し軸５は、搬送フィルム４に張力Ｆを与えるため搬送フィルム４の導出時の回転方向とは逆方向へ駆動されているので、その方向へ回転し始める。そのため、制御装置１７は、搬送フィルム４の切断や不足を、巻き出しロール６が搬送フィルム４導出時の回転方向とは逆の方向へ回転したことで検出し警報を発することができる。そして、この警報が発せられたときには、制御装置１７は巻き出しロール６の回転を即座に停止させる。なお、前記した巻き出しロール６の搬送フィルム４の導出とは逆の方向への回転は、搬送フィルム４の搬送中に搬送フィルム４が弛んだときにも短時間に発生することがあるので、それを誤検出しないように、短時間のタイマを設けてそのタイマの計時中はこの検出を禁止するようにしている。ここで、発せられる警報としては、操作モニタへの表示、警報ブザー、警告灯等の公知手段が用いられる。   Further, when the forming cycle progresses repeatedly and the conveying film 4 of the unwinding roll 6 is led out and is completely removed, the unwinding shaft 5 applies a tension F to the conveying film 4 and rotates when the conveying film 4 is led out. Since it is driven in the direction opposite to the direction, it starts to rotate in that direction. For this reason, the control device 17 can detect and alert the cutting or deficiency of the transport film 4 as the unwinding roll 6 rotates in the direction opposite to the rotation direction when the transport film 4 is led out. When this warning is issued, the control device 17 immediately stops the rotation of the unwinding roll 6. In addition, since the rotation in the direction opposite to the lead-out of the transport film 4 of the unwinding roll 6 described above may occur in a short time even when the transport film 4 is loosened during the transport of the transport film 4, In order not to detect it erroneously, a short timer is provided and this detection is prohibited while the timer is counting. Here, as an alarm to be issued, known means such as a display on an operation monitor, an alarm buzzer, and a warning light are used.

この発明は以上説明した実施例に限定されるものではなく、発明の趣旨を逸脱しない範囲内において種々の変更を付加して実施することができる。例えば、上記実施の形態では、サーボモータとロールは直結したものとして説明したが、サーボモータとロールの間に変速機が設けられる場合は、演算にその変速比が考慮されるのは当然のことである。   The present invention is not limited to the embodiments described above, and various modifications can be added and implemented without departing from the spirit of the invention. For example, in the above embodiment, the servo motor and the roll have been described as being directly connected. However, when a transmission is provided between the servo motor and the roll, it is a matter of course that the gear ratio is considered in the calculation. It is.
