Abstract

Provided are a winding core, a winding reel and a band-winding method, which are capable of preventing the band from being easily bent in a certain direction when the band is inclined to generate a difference in winding length, causing strain in winding around the band. When a carrier tape (10) is traversely wound on a curved peripheral surface (2), the peripheral surface (2) is inclined radially outward with movement from one end section toward the other end section by a cylindrical winding core (1) which overlaps one side section of the carrier tape (10) on the other side section of the wound carrier tape (10) and winds the overlapped carrier tape (10), and an inclination (θ) of the peripheral surface (2) is made to base on 0<θ≤2arctan (the thickness/traverse pitch of the carrier tape).

Description

巻取り用コア、巻取り用リール、及び帯体の巻取り方法Winding core, winding reel, and belt winding method
　本発明は、キャリアテープ等の帯体を巻き取る際に使用する巻取り用コア、巻取り用リール、及び帯体の巻取り方法に関するものである。 The present invention relates to a winding core, a take-up reel, and a winding method for a band used when winding a band such as a carrier tape.
　回路基板に電子部品を実装するとき等に使用されるキャリアテープは、巻取り用リールの巻取り用コアに巻装される。ここで、キャリアテープの生産工程や電子部品の収納工程では、巻取り用リールの交換頻度を減少させ、生産効率を向上させる観点から、より長尺のキャリアテープが巻装される。この種の巻取り用リールは、図２１や図２２に示すように、巻取り用コア１Ａと、この巻取り用コア１Ａにトラバースして巻装され、複数の電子部品を収納するキャリアテープ１０とを備えている。 The carrier tape used when mounting electronic components on the circuit board is wound around the winding core of the winding reel. Here, in the carrier tape production process and the electronic component storage process, a longer carrier tape is wound from the viewpoint of reducing the replacement frequency of the take-up reel and improving the production efficiency. As shown in FIGS. 21 and 22, this type of take-up reel is a take-up core 1A and a carrier tape 10 that traverses and winds around the take-up core 1A and stores a plurality of electronic components. And.
　巻取り用コア１Ａは、図２１や図２２に示すように、円筒形に形成されてその左右の両端面にはフランジ３がそれぞれ備えられ、キャリアテープ１０の幅よりも幅広とされている。また、キャリアテープ１０は、図２１に示すように、長いテープ１１の長手方向に、電子部品を収納する複数のポケット１２が配列形成され、テープ１１の長手方向一側部には複数のスプロケット孔１３が間隔をおいて穿孔されており、巻取り用コア１Ａの周面２Ａに連続して巻き取られる。 As shown in FIGS. 21 and 22, the winding core 1 </ b> A is formed in a cylindrical shape and is provided with flanges 3 on both left and right end surfaces thereof, and is wider than the width of the carrier tape 10. Further, as shown in FIG. 21, the carrier tape 10 has a plurality of pockets 12 for storing electronic components arranged in the longitudinal direction of the long tape 11, and a plurality of sprocket holes on one side in the longitudinal direction of the tape 11. 13 is perforated at intervals, and is continuously wound around the peripheral surface 2A of the winding core 1A.
　テープ１１の表面には、ポケット１２に電子部品が収納された後にカバーテープが着脱自在に粘着され、このカバーテープが電子部品のポケット１２からの脱落を防止し、キャリアテープ１０の繰り出し時にテープ１１から剥離される。
　このような巻取り用リールは、空の巻取り用コア１Ａにキャリアテープ１０がトラバースして巻き取られる際、キャリアテープ１０の巻き密度を向上させ、保管や搬送時の巻き崩れを防止する観点から、巻き取ったキャリアテープ１０の他側部にキャリアテープ１０の一側部が重ねて巻き取られる（特許文献１、２参照）。 The cover tape is detachably adhered to the surface of the tape 11 after the electronic component is stored in the pocket 12, and this cover tape prevents the electronic component from falling off the pocket 12, and the tape 11 is pulled out when the carrier tape 10 is unwound. Is peeled off.
Such a take-up reel has a viewpoint of improving the winding density of the carrier tape 10 when the carrier tape 10 is traversed and wound around the empty take-up core 1A and preventing collapse during storage and transportation. Then, one side portion of the carrier tape 10 is overlapped and wound on the other side portion of the wound carrier tape 10 (see Patent Documents 1 and 2).

　従来における巻取り用リールは、以上のように構成され、巻き取ったキャリアテープ１０の他側部にキャリアテープ１０の一側部が単に重ねて巻き取られるので、この重ね巻きに伴い、巻取り用コア１Ａの周面２Ａに対してキャリアテープ１０の側部が傾斜して巻き取り長さに異同を生じさせ、キャリアテープ１０の巻装に歪みが生じて一定の方向に曲がりやすくなる。 The conventional take-up reel is configured as described above, and one side of the carrier tape 10 is simply overlapped and wound on the other side of the wound carrier tape 10. The side portion of the carrier tape 10 is inclined with respect to the peripheral surface 2A of the core 1A, causing the winding length to be different, so that the winding of the carrier tape 10 is distorted and easily bent in a certain direction.
　この結果、キャリアテープ１０のポケット１２を位置決めし、このポケット１２に電子部品を挿入する際にエラーが生じたり、キャリアテープ１０のテープ１１表面にカバーテープを粘着する作業に支障を来たし、電子部品の実装時にキャリアテープ１０を円滑に繰り出すことができないおそれがある。 As a result, when the pocket 12 of the carrier tape 10 is positioned and an electronic component is inserted into the pocket 12, an error occurs, or the work of sticking the cover tape to the surface of the tape 11 of the carrier tape 10 is hindered. There is a possibility that the carrier tape 10 cannot be smoothly fed out during mounting.
　本発明は上記に鑑みなされたもので、帯体が傾いて巻き取り長さに異同を生じさせ、帯体の巻装に歪みが生じて一定の方向に曲がりやすくなるのを抑制することのできる巻取り用コア、巻取り用リール、及び帯体の巻取り方法を提供することを目的としている。 The present invention has been made in view of the above, and it is possible to suppress the belt body from being inclined and causing the winding length to be different, and the winding of the belt body being distorted and being easily bent in a certain direction.

　以下、図面を参照して本発明の実施形態を説明すると、本実施形態における巻取り用リールは、図１ないし図６に示すように、軸方向の径の相異により方向性を有する巻取り用コア１と、この巻取り用コア１にトラバースして巻装され、複数の電子部品を収納するキャリアテープ１０とを備え、回路基板に電子部品が実装される際、巻取り用コア１からキャリアテープ１０が巻き戻して順次繰り出され、このキャリアテープ１０の電子部品が回路基板に実装される。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. A winding reel according to the present embodiment has a directionality due to a difference in axial diameter as shown in FIGS. 1 to 6. Core 1 and a carrier tape 10 traversed and wound around the winding core 1 to store a plurality of electronic components. When the electronic components are mounted on a circuit board, the winding core 1 The carrier tape 10 is rewound and sequentially fed out, and the electronic components of the carrier tape 10 are mounted on the circuit board.
　巻取り用コア１は、図１、図２、図５に示すように、例えば所定の樹脂を含む成形材料を使用して中空の略円錐台形に成形され、左右の一端部から他端部方向、換言すれば、軸方向に向かうにしたがい周面２が半径外方向に徐々に傾斜形成されており、巻取り装置の駆動軸にセットされる。この巻取り用コア１の成形材料としては、特に限定されるものではないが、例えば成形性や軽量性等に優れるＡＢＳ樹脂、ポリスチレン、発泡ポリスチレン（ＰＳＰ）、ポリオレフィン、発泡ポリオレフィン等があげられる。巻取り用コア１の左右両端面は、それぞれ開口形成され、円板形のフランジ３がそれぞれ着脱自在に装着される。 As shown in FIGS. 1, 2, and 5, the winding core 1 is formed into a hollow substantially truncated cone shape using a molding material containing a predetermined resin, for example, from the left and right ends to the other end. In other words, the circumferential surface 2 is gradually inclined outward in the radial direction along the axial direction, and is set on the drive shaft of the winding device. The molding material of the winding core 1 is not particularly limited, and examples thereof include ABS resin, polystyrene, expanded polystyrene (PSP), polyolefin, and expanded polyolefin that are excellent in moldability and light weight. The left and right end surfaces of the winding core 1 are respectively formed with openings, and disc-shaped flanges 3 are detachably attached thereto.
　係るフランジ３の装着に際しては、巻取り用コア１の端面に複数の係止爪をそれぞれ突出形成し、フランジ３に、各係止爪と係止する係止孔９を穿孔したり、あるいは巻取り用コア１の端面に複数の係止溝をそれぞれ形成し、フランジ３には、各係止溝と係止する係止爪を形成すると良い。 When the flange 3 is mounted, a plurality of locking claws are formed to protrude from the end face of the winding core 1, and a locking hole 9 to be locked to each locking claw is formed in the flange 3 or the winding is wound. A plurality of locking grooves may be formed on the end surface of the take-up core 1, and locking claws that lock the locking grooves may be formed on the flange 3.
　キャリアテープ１０は、図１、図２、図６に示すように、可撓性を有する長尺のテープ１１を備え、このテープ１１の長手方向に、電子部品を収納する有底角筒形のポケット１２が複数配列形成され、テープ１１の長手方向一側部には複数のスプロケット孔１３が間隔をおいて穿孔されており、巻取装置の左右方向にスライド可能なガイドローラ２０により巻取り用コア１の左右横方向に移動しながら、巻取り用コア１の湾曲した周面２に連続して巻き取られる。 As shown in FIGS. 1, 2, and 6, the carrier tape 10 is provided with a long tape 11 having flexibility, and in the longitudinal direction of the tape 11, a bottomed rectangular tube shape that accommodates electronic components is provided. A plurality of pockets 12 are formed in an array, and a plurality of sprocket holes 13 are perforated on one side in the longitudinal direction of the tape 11 for winding by a guide roller 20 slidable in the left-right direction of the winding device. The core 1 is continuously wound on the curved peripheral surface 2 of the winding core 1 while moving in the horizontal direction of the core 1.
　キャリアテープ１０は、例えばポリスチレン、ポリエチレンテレフタレート、ポリカーボネート等からなる成形材料により１２００ｍ以上の長さに成形され、必要に応じて導電性等が選択的に付与される。テープ１１の表面には、ポケット１２に電子部品が収納された後に図示しないカバーテープが加熱・超音波シールされたり、あるいは着脱自在に粘着され、このカバーテープが電子部品のポケット１２からの脱落を防止し、キャリアテープ１０の繰り出し時にテープ１１から剥離される。また、電子部品は、特に限定されるものではないが、例えばＬＥＤ、セラミックコンデンサ、チップ抵抗、電気コネクタ、トランジスタ等があげられる。 The carrier tape 10 is molded to a length of 1200 m or more by a molding material made of, for example, polystyrene, polyethylene terephthalate, polycarbonate, etc., and conductivity or the like is selectively given as necessary. A cover tape (not shown) is heated, ultrasonically sealed, or detachably adhered to the surface of the tape 11 after the electronic component is stored in the pocket 12, and the cover tape prevents the electronic component from dropping from the pocket 12. To prevent the carrier tape 10 from being peeled off. The electronic component is not particularly limited, and examples thereof include an LED, a ceramic capacitor, a chip resistor, an electrical connector, and a transistor.
　キャリアテープ１０の巻き取りに際しては、巻き取られたキャリアテープ１０の他側部にキャリアテープ１０の一側部が重ねて巻き取られる重ね巻き（図１参照）と、巻き取られたキャリアテープ１０の他側部にキャリアテープ１０が重なることなく隣接して巻き取られる普通巻き（図２参照）とが交互に繰り返される。例えば、巻取り用コア１の左端から右端までキャリアテープ１０を巻き取る場合には、キャリアテープ１０が重ね巻きされ、巻取り用コア１の右端から左端までキャリアテープ１０を巻き取る場合には、キャリアテープ１０が普通巻きされる。 When winding the carrier tape 10, a lap winding (see FIG. 1) in which one side portion of the carrier tape 10 is overlapped and wound on the other side portion of the wound carrier tape 10, and the wound carrier tape 10 is wound. Ordinary winding (see FIG. 2) in which the carrier tape 10 is wound adjacently without overlapping the other side portion is repeated alternately. For example, when the carrier tape 10 is wound from the left end to the right end of the winding core 1, the carrier tape 10 is overwrapped, and when the carrier tape 10 is wound from the right end to the left end of the winding core 1, The carrier tape 10 is normally wound.
　さて、巻取り用コア１はキャリアテープ１０の重なり部の傾きとは逆の方向に周面２がテーパーに形成される（図３参照）が、この周面２の傾きθは、０＜θ≦２ａｒｃｔａｎ〔キャリアテープの厚み／トラバースピッチ〕に基づいて決定される。これは、重ね巻きの際、キャリアテープ１０の傾きθｃは、θｃ＝ａｒｃｔａｎ〔キャリアテープの厚み／トラバースピッチ〕と考えられるからである（図４参照）。 Now, the winding core 1 has a circumferential surface 2 tapered in a direction opposite to the inclination of the overlapping portion of the carrier tape 10 (see FIG. 3). The inclination θ of the circumferential surface 2 is 0 <θ. ≦ 2 arctan [carrier tape thickness / traverse pitch] This is because the inclination θ c of the carrier tape 10 is considered to be θ c = arctan [carrier tape thickness / traverse pitch] during lap winding (see FIG. 4).
　例えば、キャリアテープ１０の傾きθｃは、キャリアテープ１０の厚みが０．２５ｍｍ、トラバースピッチが５．７ｍｍの場合、θｃ≒２．５となる。これにより、巻取り用コア１の周面２の最適な傾きθは、キャリアテープ１０の厚み、トラバースピッチ、製品のエンボス形状により異なるものの、概ね０＜θ≦２θｃが適性と考えられる。具体的には、１°～５°、好ましくは１．５°～５°、より好ましくは１．５°程度が良い。 For example, the inclination theta c of the carrier tape 10, the thickness of the carrier tape 10 is 0.25 mm, if the traverse pitch of 5.7 mm, a theta c ≒ 2.5. Thus, although the optimum inclination θ of the peripheral surface 2 of the winding core 1 varies depending on the thickness of the carrier tape 10, the traverse pitch, and the embossed shape of the product, it is considered that 0 <θ ≦ 2θ c is appropriate. Specifically, it is 1 ° to 5 °, preferably 1.5 ° to 5 °, more preferably about 1.5 °.
　上記構成において、巻取り用リールの巻取り用コア１にキャリアテープ１０をトラバースして巻き取る場合には、巻取り装置の駆動軸に空の巻取り用コア１を嵌合し、この巻取り用コア１にキャリアテープ１０の端部を巻き付けるとともに、巻取装置のガイドローラ２０にキャリアテープ１０を緊張して巻きかけ、その後、巻取り装置を駆動して巻取り用コア１の周面２にキャリアテープ１０を左方向あるいは右方向に移動させつつ巻き取れば良い。 In the above configuration, when the carrier tape 10 is traversed and wound on the winding core 1 of the winding reel, the empty winding core 1 is fitted to the drive shaft of the winding device, and this winding is performed. The end of the carrier tape 10 is wound around the core 1 and the carrier tape 10 is tensioned around the guide roller 20 of the winding device, and then the winding device is driven to drive the peripheral surface 2 of the winding core 1. In addition, the carrier tape 10 may be wound while moving the carrier tape 10 leftward or rightward.
　すると、巻取り用コア１が回転してキャリアテープ１０を巻き取り、このキャリアテープ１０の重ね巻き、普通巻き、重ね巻き、普通巻き…が交互に繰り返されることにより、巻取り用コア１にキャリアテープ１０がトラバースして完全に巻き取られる。すなわち、キャリアテープ１０は、巻取り用コア１の径が小さい左端部から径の大きな右端部にかけては重ね巻きされるとともに、右端部から左端部にかけては普通巻きされ、これらの異なる巻き方が交互に繰り返される。 Then, the winding core 1 rotates to wind up the carrier tape 10, and the carrier tape 10 is wound on the winding core 1 by alternately repeating lap winding, normal winding, lap winding, normal winding,. The tape 10 traverses and is completely wound up. That is, the carrier tape 10 is lap-wound from the left end portion where the diameter of the winding core 1 is small to the right end portion where the diameter is large, and is normally wound from the right end portion to the left end portion. Repeated.
　したがって、キャリアテープ１０の重ね巻きの場合には、巻取り用コア１の傾斜角度が０°より小さくなることがなく、常に一定の傾斜角度（０＜θ＜２θｃ）を保つことができる。これにより、キャリアテープ１０の曲がりを効果的に低減することが大いに期待できる。 Therefore, in the case of lap winding of the carrier tape 10, the inclination angle of the winding core 1 does not become smaller than 0 °, and a constant inclination angle (0 <θ <2θ c ) can always be maintained. Thereby, it can be greatly expected that the bending of the carrier tape 10 is effectively reduced.
　係るキャリアテープ１０の巻き取りの際、巻取り用コア１の周面２がキャリアテープ１０の重なり部の傾きとは逆の方向に傾斜するので、キャリアテープ１０の重なり部の傾きを著しく緩和することができ、重ね巻きに伴い、巻取り用コア１の周面２に対してキャリアテープ１０の側部が傾斜して巻き取り長さや径に異同を生じさせることがない。 When winding the carrier tape 10, the peripheral surface 2 of the winding core 1 is inclined in a direction opposite to the inclination of the overlapping portion of the carrier tape 10, so that the inclination of the overlapping portion of the carrier tape 10 is remarkably reduced. Thus, the side portions of the carrier tape 10 are not inclined with respect to the peripheral surface 2 of the winding core 1 with the lap winding so that the winding length and the diameter are not different.
　したがって、キャリアテープ１０の巻装に歪みが生じて一定の方向に大きく曲がるのを確実に防止することができ、この結果、キャリアテープ１０のポケット１２を位置決めし、このポケット１２に電子部品を挿入する際にエラーが生じるのを抑制防止することができる。また、キャリアテープ１０のテープ１１表面にカバーテープを簡易、かつ容易に粘着したり、電子部品の実装時に巻き取ったキャリアテープ１０を円滑に繰り出すことができる。 Accordingly, the winding of the carrier tape 10 can be reliably prevented from being bent and greatly bent in a certain direction. As a result, the pocket 12 of the carrier tape 10 is positioned and an electronic component is inserted into the pocket 12. It is possible to suppress and prevent the occurrence of errors when In addition, the cover tape can be easily and easily adhered to the surface of the tape 11 of the carrier tape 10, or the carrier tape 10 taken up when the electronic component is mounted can be smoothly fed out.

〔Example〕
　以下、本発明に係る巻取り用コア、巻取り用リール、及び帯体の巻取り方法の実施例を比較例と共に説明する。
〔実施例１〕
　先ず、巻取り装置の駆動軸に空の巻取り用コアを嵌合し、この巻取り用コアにキャリアテープの端部を巻き付け、巻取装置のガイドローラにキャリアテープを緊張して巻きかけた。巻取り用コアの周面には、１．５°のテーパーを半径外方向に形成した。また、キャリアテープとして、テープの幅が８ｍｍ、各ポケットの深さが１．４２ｍｍで、テープの長手方向一側部に複数のスプロケット孔が間隔をおいて穿孔されたタイプを使用した。 Examples of the winding core, the winding reel, and the belt winding method according to the present invention will be described below together with comparative examples.
[Example 1]
First, an empty winding core was fitted to the drive shaft of the winding device, the end of the carrier tape was wound around the winding core, and the carrier tape was tensioned and wound around the guide roller of the winding device. . On the peripheral surface of the winding core, a taper of 1.5 ° was formed in the radially outward direction. The carrier tape used was a type in which the tape width was 8 mm, the depth of each pocket was 1.42 mm, and a plurality of sprocket holes were perforated at one side in the longitudinal direction of the tape.
　巻取装置のガイドローラにキャリアテープを巻きかけたら、巻取り装置を駆動して巻取り用コアの周面にキャリアテープを左方向あるいは右方向に移動させつつ巻き取り、キャリアテープの曲がりを測定し、この測定結果を図１４、図１５のグラフにまとめた。キャリアテープの巻き取りに際しては図１３に示すように、キャリアテープの重ね巻きと普通巻きとを交互に繰り返した。 When the carrier tape is wound around the guide roller of the winding device, the winding device is driven to wind the carrier tape around the winding core while moving the carrier tape leftward or rightward to measure the bending of the carrier tape. The measurement results are summarized in the graphs of FIGS. When winding the carrier tape, as shown in FIG. 13, the overlap winding and the normal winding of the carrier tape were alternately repeated.
　重ね巻きの際、キャリアテープの傾きθｃは、θｃ≒２．５であった。また、キャリアテープの曲がりの測定に際しては、重ね巻き層の端部から開始し、普通巻き層の元の端部まで測定して終了した。キャリアテープの曲がりは、スプロケット孔の穿孔された一側部が伸びた場合をプラス、スプロケット孔のない他側部が伸びた場合をマイナスとして測定した。図１４の左端は測定の開始点、中央付近の点線は反対側のフランジ付近、右端は測定開始点側のフランジを示している。また、図１５の中央付近の点線は、キャリアテープの重ね巻きから普通巻きへの変更点を示している。 At the time of lap winding, the inclination θ c of the carrier tape was θ c ≈2.5. Moreover, in measuring the bending of the carrier tape, the measurement was started from the end portion of the overlapped winding layer, and finished by measuring to the original end portion of the normal winding layer. The bending of the carrier tape was measured as positive when one side of the sprocket hole was extended and negative when the other side without the sprocket hole was extended. The left end of FIG. 14 indicates the measurement start point, the dotted line near the center indicates the vicinity of the opposite flange, and the right end indicates the measurement start point side flange.
