Description

本発明は、シートの巻取り方法及び装置並びにシート巻取り体に関する。   The present invention relates to a sheet winding method and apparatus, and a sheet winding body.

シートを円筒状の芯部材に巻き取る場合に、シートの巻取り方向先端に段差が生じ、シート巻取り体の外観が損なわれ、段差による凹凸が大きい場合には層間で剥離等の欠陥を生じる。また、巻き取られるシート間に段差が生じると、その段の上に巻き取られる部分が皺となり、この皺が積み重ねられてコブ状となり、例えば数メートルに渡って不良品が発生する。特に粘着テープを巻き取る場合は、シート間に滑りが生じないために凹凸が緩和されず、凹凸が顕著に出現してしまうので、巻き始めに凹凸を緩和することが特に重要となる。このため、シートを巻き取る際に生じるシート端面由来の凹凸を抑制する方法が従来より提案されている。例えば特許文献１においては、芯部材に、スポンジ等の発泡体や密度の低い紙等の弾性変形や塑性変形を起こしやすい変形体を用いて、巻き始めの端部によってできる段差により、シートの表面に段差の痕跡、つまり巻き始めの端部の段差が転写した凹みが発生するのを防止する方法が開示されている。   When a sheet is wound around a cylindrical core member, a step is formed at the leading end of the sheet in the winding direction, and the appearance of the sheet winding body is damaged. . Further, when a step is generated between the wound sheets, a portion wound on the step becomes a wrinkle, and the wrinkles are stacked to form a hump, and a defective product is generated over several meters, for example. In particular, when winding an adhesive tape, since unevenness is not relieved because no slip occurs between the sheets, and unevenness appears remarkably, it is particularly important to relieve the unevenness at the beginning of winding. For this reason, a method for suppressing unevenness derived from the sheet end face that occurs when the sheet is wound has been proposed. For example, in Patent Document 1, the surface of the sheet is formed by a step formed by an end portion at the start of winding, using a foam member such as sponge or a deformable body such as low-density paper that easily undergoes elastic deformation or plastic deformation. Discloses a method for preventing a trace of a step, that is, a dent transferred by a step at the end of winding from occurring.

しかし、発泡体や低密度の紙等の変形体は、弾性変形の割合が大きく、塑性変形を起こしにくいことから応力が生じるため、段差によってシート状部材に生じる凹凸を完全に消し去ることは難しい。そこで、従来から、断面くさび型の柔軟部材をシートの端部にあてがってシート表面と芯部材表面との段差をなだらかに埋める方法が提案されている（特許文献２）。   However, deformed bodies such as foam and low-density paper have a large elastic deformation ratio and are difficult to cause plastic deformation, so stress is generated, and thus it is difficult to completely erase the unevenness generated in the sheet-like member due to the step. . Therefore, conventionally, a method has been proposed in which a stepwise difference between the sheet surface and the core member surface is gently filled by applying a wedge-shaped flexible member to the end of the sheet (Patent Document 2).

しかしながら、従来においては、芯部材に対して切削加工を施したり、あるいは芯部材に発泡体を巻く等、芯部材に対して特別な加工が必要であるという問題点があった。   However, conventionally, there has been a problem that special processing is required for the core member, such as cutting the core member or winding a foam around the core member.

本発明の第２の特徴とするところは、シートを巻き取る芯部材を回転させる駆動装置と、前記シートの先端が前記芯部材に当たる際に前記シートの巻取り方向先端を加熱する加熱手段と、を有するシートの巻取り装置にある。   The second feature of the present invention is that a driving device that rotates a core member that winds up a sheet, and a heating unit that heats the leading end of the sheet in the winding direction when the leading end of the sheet hits the core member, A sheet take-up device.

本発明によれば、芯部材に加工を施さなくともシートの凹凸を少なくすることができる。   According to the present invention, the unevenness of the sheet can be reduced without processing the core member.

次に本発明の実施形態について図面に基づいて説明する。
図１において、本発明の実施形態に係るシート巻取り装置１０が示されている。このシート巻取り装置１０は、シート１２を円筒状の芯部材１４に巻き取るためのものである。 Next, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a sheet winding device 10 according to an embodiment of the present invention. The sheet winding device 10 is for winding a sheet 12 around a cylindrical core member 14.

シート１２は、例えば熱可塑性樹脂シートである。熱可塑性樹脂には、周知のように、汎用樹脂として、ポリエチレン、ポリプロピレン、ポリスチレン(PS)、アクリロトリル/ブタンジエン/スチレン樹脂(ABS)、ポリ塩化ビニル(PVC)、アクリロニトリル/スチレン樹脂(AS)、メタクリル樹脂(PMMA)等があり、汎用エンジニアリング樹脂として、ポリアミド(PA)、ポリアセタール(POM)、ポリカーボネート(PC)、変性ポリフェニレンエーテル(m-PPE)、ポリブチレンテレフタレート(PBT)、GF強化ポリエチレンテレフタレート(GF-PET)、超高分子量ポリエチレン(UHPE)等があり、さらにスーパーエンジニアリング樹脂として、ポリフェニレンスルフィド(PPS)、ポリイミド(PI)、ポリエーテルイミド(PEI)、ポリアリレート(PAR)、ポリスルホン(PSF)、ポリエーテルスルホン(PES)、ポリエーテルエーテルケトン(PEEK)、液晶ポリマー(LCP)、ポリテトラフルオロエチレン(PTFE)等がある。さらに熱可塑性樹脂として、アイモノマー、エチレン−酢酸ビニル樹脂がある。
特に好ましいのは、ポリエチレン系やポリプロピレン系等のポリオレフィン系である。
なお、シート１２の先端裏面には、低い温度で芯部材１４に接着されるように、シート１２の本体部よりも低い軟化点又は溶融点を有する接着層を設けることができる。
さらにシート１２としては、基材フィルムに粘着剤を設けたもの、例えば基材フィルムの片面に粘着剤を塗布したダイシング用の粘着シートであってもよい。 The sheet 12 is, for example, a thermoplastic resin sheet. As is well known, thermoplastic resins include general-purpose resins such as polyethylene, polypropylene, polystyrene (PS), acrylotolyl / butanediene / styrene resin (ABS), polyvinyl chloride (PVC), acrylonitrile / styrene resin (AS), methacrylic resin. Resin (PMMA) -PET), ultra high molecular weight polyethylene (UHPE), etc., and also as a super engineering resin, polyphenylene sulfide (PPS), polyimide (PI), polyetherimide (PEI), polyarylate (PAR), polysulfone (PSF), Polyethersulfone (PES), polyetheretherketone (PEEK), liquid crystal polymer (LCP), It is Li polytetrafluoroethylene (PTFE) or the like. Further, examples of the thermoplastic resin include an eye monomer and an ethylene-vinyl acetate resin.
Particularly preferred are polyolefins such as polyethylene and polypropylene.
Note that an adhesive layer having a softening point or a melting point lower than that of the main body of the sheet 12 can be provided on the back surface of the front end of the sheet 12 so as to be bonded to the core member 14 at a low temperature.
Further, the sheet 12 may be a dicing adhesive sheet in which an adhesive is provided on a base film, for example, an adhesive is applied to one side of the base film.

芯部材１４は、耐熱性を有する材料から構成され、例えばステンレス等の金属、又はＡＢＳ等の樹脂からなる。この芯部材１４は、円筒状に形成されて周囲に巻取り面を有し、この巻取り面にシート１２が巻き取られる。   The core member 14 is made of a material having heat resistance, and is made of a metal such as stainless steel or a resin such as ABS. The core member 14 is formed in a cylindrical shape and has a winding surface around it, and the sheet 12 is wound around the winding surface.

搬送ロール１６は、芯部材１４の上流側に設けられ、シート１２を芯部材１４の上端に向けて搬送する。この搬送ロール１６は、モータからなる第１の駆動装置１８により回転駆動される。   The conveyance roll 16 is provided on the upstream side of the core member 14 and conveys the sheet 12 toward the upper end of the core member 14. The transport roll 16 is rotationally driven by a first driving device 18 made of a motor.

前述した芯部材１４は、同じくモータからなる第２の駆動装置２０により、図中時計方向に回転される。   The core member 14 described above is rotated in the clockwise direction in the figure by the second driving device 20 also comprising a motor.

シート検出器２２は、例えば搬送ロール１６の出口部分に設けられている。このシート検出器２２は、例えば発光素子と受光素子からなり、発光素子からの光を受光素子が受けた状態からシートの先端が発光素子と受光素子との間を通過すると、光の一部又は全部が遮断されてシートの先端が通過したことを検出する。また、光が遮断された状態からシートの後端が受光素子と発光素子との間を通過すると、受光素子により光が受光されてシートの後端が通過したことを検出する。   The sheet detector 22 is provided, for example, at the exit portion of the transport roll 16. The sheet detector 22 includes, for example, a light emitting element and a light receiving element. When the leading end of the sheet passes between the light emitting element and the light receiving element from a state where the light receiving element receives light from the light emitting element, a part of the light or It is detected that the whole has been blocked and the leading edge of the sheet has passed. Further, when the rear end of the sheet passes between the light receiving element and the light emitting element from the state where the light is blocked, it is detected that the light is received by the light receiving element and the rear end of the sheet has passed.

加熱手段を構成する加熱部材２４は、例えば円筒状に形成され、表面に例えばフッ素樹脂等の離型層を有し、内部にはヒータ２６が配置されており、このヒータ２６に通電することによって表面を加熱することができる。また、加熱部材２４の表面の温度を検出する温度センサ２８が設けられている。
なお、この実施形態においては、加熱部材２４の内部にヒータ２６を設けたが、他の実施形態として、加熱部材２４を外部から加熱するようにしてもよい。 The heating member 24 constituting the heating means is formed in a cylindrical shape, for example, has a release layer such as a fluororesin on the surface, and a heater 26 is disposed inside, and when the heater 26 is energized, The surface can be heated. Further, a temperature sensor 28 that detects the temperature of the surface of the heating member 24 is provided.
In this embodiment, the heater 26 is provided inside the heating member 24. However, as another embodiment, the heating member 24 may be heated from the outside.

上記加熱部材２４は、アーム３０に支持されている。このアーム３０は、モータである第３の駆動装置３２により回転される。加熱部材２４は、実線で示す位置を初期位置として、第３の駆動装置３２からの駆動を受けて反時計方向に回転し、２点鎖線で示すように、芯部材１４の上端付近を通り、さらに回転して初期位置に戻されるようになっている。   The heating member 24 is supported by the arm 30. The arm 30 is rotated by a third driving device 32 that is a motor. The heating member 24 receives the drive from the third drive device 32 and rotates counterclockwise with the position indicated by the solid line as the initial position, passes through the vicinity of the upper end of the core member 14 as indicated by the two-dot chain line, Further, it is rotated and returned to the initial position.

加熱部材２４は、２点鎖線で示す位置まで移動した時に芯部材１４に最も近づく。この場合の加熱部材２４と芯部材１４との間の距離はシート１２の厚さよりも小さく、略０となるようにすることが好ましい。また、加熱部材２４の公転による周速は、芯部材１４の周速よりも速い方が好ましい。加熱部材２４の周速が芯部材１４の周速よりも速いことにより、シート１２の先端を滑らかな曲面をもって徐々に薄く形成することができる。   The heating member 24 is closest to the core member 14 when moved to the position indicated by the two-dot chain line. In this case, the distance between the heating member 24 and the core member 14 is preferably smaller than the thickness of the sheet 12 and substantially zero. Further, the peripheral speed due to the revolution of the heating member 24 is preferably higher than the peripheral speed of the core member 14. Since the peripheral speed of the heating member 24 is faster than the peripheral speed of the core member 14, the tip of the sheet 12 can be gradually formed with a smooth curved surface.

なお、加熱部材２４は、アーム３０に固定されるようにしてもよいが、アーム３０に回転自在に支持されるようにしてもよく、さらに反時計方向に回転駆動されるようにしてもよい。この場合、加熱部材２４の自転による周速は、芯部材１４の周速よりも速い方が好ましい。加熱部材２４の周速が芯部材１４の周速よりも速いことにより、シート１２の先端を滑らかな曲面をもって徐々に薄く形成することができる。   The heating member 24 may be fixed to the arm 30 but may be rotatably supported by the arm 30 and may be further driven to rotate counterclockwise. In this case, the peripheral speed due to the rotation of the heating member 24 is preferably higher than the peripheral speed of the core member 14. Since the peripheral speed of the heating member 24 is faster than the peripheral speed of the core member 14, the tip of the sheet 12 can be gradually formed with a smooth curved surface.

制御部３４は、例えばコンピュータから構成され、シート検出器２２及び温度センサ２８からの検出信号が入力されると共に、第１の駆動装置１８、第２の駆動装置２０、第３の駆動装置３０及びヒータ２６を制御する。   The control unit 34 is configured by a computer, for example, and receives detection signals from the sheet detector 22 and the temperature sensor 28, and also includes a first driving device 18, a second driving device 20, a third driving device 30, and the like. The heater 26 is controlled.

図２において、上記制御部３４の制御フローが示されている。
まず、ステップＳ１０において、温度センサ２８からの検出信号をモニタしながらヒータ２６に通電して加熱部材２４の表面を所定温度以上に加熱する。所定温度とは、シート１２との接触時にシート１２が軟化点又は溶融点以上となる温度である。軟化点とは、物体が温度により変形を起こし始める温度であり、溶融点とは、物体が固体から液体へ相変化を起こし始める温度である。 In FIG. 2, the control flow of the control unit 34 is shown.
First, in step S10, the heater 26 is energized while monitoring the detection signal from the temperature sensor 28 to heat the surface of the heating member 24 to a predetermined temperature or higher. The predetermined temperature is a temperature at which the sheet 12 becomes a softening point or a melting point or higher when in contact with the sheet 12. The softening point is a temperature at which an object starts to deform due to temperature, and the melting point is a temperature at which the object starts to undergo a phase change from a solid to a liquid.

次のステップＳ１２においては、第１の駆動装置１８を駆動して搬送ロール１６を回転させ、シート１２を芯部材１４の上端に向けて搬送する。次のステップ１４においては、第２の駆動装置２０を駆動して芯部材１４を回転させ、シート巻取りの準備を行う。   In the next step S <b> 12, the first driving device 18 is driven to rotate the conveyance roll 16 and convey the sheet 12 toward the upper end of the core member 14. In the next step 14, the second driving device 20 is driven to rotate the core member 14 to prepare for sheet winding.

次のステップＳ１６においては、シート検出器２２からの出力に基づいてシート１２の先端がシート検出器２２を通過したか否かを判定する。このステップ１６において、シート１２の先端がシート検出器２２を通過したと判定された場合は次のステップＳ１８に進み、シート１２の先端がシート検出器２２を未だ通過していないと判定された場合にはシート１２の先端が検出されるまで待機する。   In the next step S <b> 16, it is determined whether or not the leading end of the sheet 12 has passed through the sheet detector 22 based on the output from the sheet detector 22. If it is determined in step 16 that the leading edge of the sheet 12 has passed the sheet detector 22, the process proceeds to the next step S18, and if it is determined that the leading edge of the sheet 12 has not yet passed the sheet detector 22. Wait until the leading edge of the sheet 12 is detected.

ステップＳ１８においては、シート１２の先端が芯部材１４の上端の巻取り開始位置に到達した時に加熱部材２４が巻取り開始位置に到達するように、シート検出器２２からの出力に基づいてタイミングをとって第３の駆動装置３０を駆動する。そして、加熱部材２４が図１の２点鎖線の位置からさらに反時計方向に回転し、初期位置に到達した段階でステップＳ２０に進み、第３の駆動承知３０の駆動を停止して加熱部材２４を初期位置に戻す。さらに次のステップＳ２２においては、ヒータ２６の加熱を停止する。   In step S18, the timing is determined based on the output from the sheet detector 22 so that the heating member 24 reaches the winding start position when the leading end of the sheet 12 reaches the winding start position at the upper end of the core member 14. Thus, the third driving device 30 is driven. Then, when the heating member 24 further rotates counterclockwise from the position of the two-dot chain line in FIG. 1 and reaches the initial position, the process proceeds to step S20, and the driving of the third drive acknowledge 30 is stopped and the heating member 24 is stopped. Return to the initial position. Further, in the next step S22, the heating of the heater 26 is stopped.

次のステップＳ２４においては、シート１２の芯部材１４への巻取りが終了したか否かを判定する。巻取りが終了したか否かの判定は、例えばシート検出器２２によりシート１２の後端が通過した時から所定時間が経過したか否かにより行うことができる。このステップＳ２４において、シート１２の巻取りが終了したと判定された場合は、次のステップＳ２６に進み、シート１２の巻取りが終了していないと判定された場合、シート１２の巻取りが終了するまで待機する。   In the next step S24, it is determined whether or not the winding of the sheet 12 around the core member 14 is completed. Whether or not the winding has been completed can be determined based on whether or not a predetermined time has elapsed since the trailing edge of the sheet 12 has passed by the sheet detector 22, for example. If it is determined in step S24 that the winding of the sheet 12 has been completed, the process proceeds to the next step S26, and if it is determined that the winding of the sheet 12 has not been completed, the winding of the sheet 12 is completed. Wait until

次のステップＳ２６においては、第１の駆動装置１８の駆動を停止して搬送ロール１６の回転を停止し、次のステップＳ２８において、第２の駆動措置２０の駆動を停止して芯部材１４の回転を停止し、処理を終了する。   In the next step S26, the driving of the first driving device 18 is stopped and the rotation of the transport roll 16 is stopped. In the next step S28, the driving of the second driving means 20 is stopped and the core member 14 is stopped. Stop the rotation and finish the process.

次に上述したシートの巻取り方法を実施した場合の作用について説明する。
図３に示すように、シート１２が芯部材１４に巻かれる開始位置でシート１２の軟化点又は溶融点以上に加熱された加熱部材２４がシート１２の先端に押圧するように接触するので、シート１２の先端は加熱部材２４からの熱及び圧力により、先端に向かって徐々に薄くなるように変形される。即ち、図４に示すように、シート１２は、先端部３６が本体部３８よりも徐々に薄くなるように滑らかな曲面となるように変形され、段差が軽減される。ここで、段差とは、シート１２を巻き取る際のシート先端により発生する芯部材１４とシート１２との半径方向の差をいう。 Next, the operation when the above-described sheet winding method is performed will be described.
As shown in FIG. 3, since the heating member 24 heated to the softening point or the melting point of the sheet 12 is brought into contact with the leading end of the sheet 12 at the start position where the sheet 12 is wound around the core member 14, the sheet 12 The tip of 12 is deformed so as to become gradually thinner toward the tip by the heat and pressure from the heating member 24. That is, as shown in FIG. 4, the sheet 12 is deformed so as to have a smooth curved surface so that the front end portion 36 becomes gradually thinner than the main body portion 38, and the level difference is reduced. Here, the level difference means a difference in the radial direction between the core member 14 and the sheet 12 generated by the leading end of the sheet when the sheet 12 is wound.

このような変形と同時にシート１２の先端部３６には加熱部材２４からの熱及び圧力が作用するので、先端部３６の裏面が芯部材１４に接着され、シート１２の先端が芯部材１４から離れることなくシート１２を芯部材１４に巻き取ることができる。   Simultaneously with such deformation, heat and pressure from the heating member 24 act on the leading end portion 36 of the sheet 12, so that the back surface of the leading end portion 36 is bonded to the core member 14 and the leading end of the sheet 12 is separated from the core member 14. The sheet 12 can be wound around the core member 14 without any problem.

そして、図５に示すように、２周目のシート１２が先端部を乗り上げるように巻き付けられるので、シート１２の凹凸の発生を少ないシート巻取り体４０を得ることができる。ここで、凹凸とは、シート１２の先端により発生した段差が巻取り済みのシートに転写されることにより生じる凹凸をいう。   And since the sheet | seat 12 of the 2nd round is wound so that it may ride on a front-end | tip part as shown in FIG. 5, the sheet | seat winding body 40 with few generation | occurrence | production of the unevenness | corrugation of the sheet | seat 12 can be obtained. Here, the unevenness means an unevenness generated by transferring a step generated by the front end of the sheet 12 to the wound sheet.

次に実施例について説明する。
厚さ２５μｍのアクリル樹脂粘着剤層をもつアイモノマー樹脂フィルムを１０ｃｍ／分の搬送速度で搬送しながら、ＡＢＳ樹脂製の芯部材にロール状に巻き取るにあたり、フィルム先端を芯部材にあてがい、２００°Ｃ以上に加熱したＳＵＳ３０４製の加熱部材に接触させた後、芯部材に巻き取った。なお、加熱部材はフィルム先端に接触、加工後、即時にフィルムから離反させた。加熱部材を用いずに巻き取ったものと比較して凹凸が少ないフィルム巻取り体を得ることができた。 Next, examples will be described.
While winding an eye monomer resin film having an acrylic resin pressure-sensitive adhesive layer having a thickness of 25 μm at a transport speed of 10 cm / min while winding it around a core member made of ABS resin in a roll shape, the film tip is applied to the core member, 200 After making it contact with the heating member made from SUS304 heated to ° C or more, it was wound around the core member. The heating member was brought into contact with the film tip and immediately separated from the film after processing. A film winding body with less unevenness than that wound without using a heating member could be obtained.
