Description

リール保持装置Reel holding device
　本発明は、オートローディングフィーダと組み合わせて使用され、キャリアテープをそれぞれ巻回した２個のテープリールを回転可能に保持するリール保持装置に関する。 The present invention relates to a reel holding device that is used in combination with an autoloading feeder and rotatably holds two tape reels each wound with a carrier tape.
　多数の電子部品が装着された基板を生産する設備として、はんだ印刷機、電子部品装着機、リフロー機、基板検査機などがある。これらの設備を連結して基板生産ラインを構成することが一般的になっている。このうち電子部品装着機は、基板搬送装置、部品供給装置、部品移載装置、および制御装置を備える。部品供給装置の代表例として、複数の部品収納部にそれぞれ電子部品を収納したキャリアテープを繰り出す方式のフィーダがある。近年、第１のキャリアテープの後端に続いて第２のキャリアテープを自動的に繰り出す機能を備え、スプライシング作業を省略するようにしたオートローディングフィーダが広まりつつある。オートローディングフィーダと組み合わせて使用されるリール保持装置は、２個のテープリールを回転可能かつ交換可能に保持する。この種のリール保持装置に関する一技術例が、特許文献１に開示されている。 There are solder printing machines, electronic component mounting machines, reflow machines, board inspection machines, etc. as equipment for producing boards with a large number of electronic components mounted. It has become common to configure a substrate production line by connecting these facilities. Among these, the electronic component mounting machine includes a substrate transfer device, a component supply device, a component transfer device, and a control device. As a typical example of the component supply device, there is a feeder that feeds out carrier tapes each storing electronic components in a plurality of component storage units. In recent years, autoloading feeders that have a function of automatically feeding the second carrier tape following the rear end of the first carrier tape and omitting the splicing operation are becoming widespread. A reel holding device used in combination with an autoloading feeder holds two tape reels in a rotatable and replaceable manner. One technical example regarding this type of reel holding device is disclosed in Patent Document 1.
　特許文献１の実施形態に開示されたキャリアテープ自動供給装置は、自動供給装置本体の後方に回動可能に結合されたリール据置台と、リール据置台の下端部に回動可能にヒンジ結合された回転バーとを備え、回転バーの両端に第１リールおよび第２リールが取り付けられる。これによれば、第１リールに巻き取られている第１キャリアテープが全て消尽されると、第２キャリアテープが移送されるが、この際に第１リールが第２リールに交替されるようになっている。 The carrier tape automatic supply device disclosed in the embodiment of Patent Document 1 is a reel mount that is pivotally coupled to the rear of the automatic feeder main body and a hinge that is pivotally coupled to the lower end of the reel mount. And a first reel and a second reel are attached to both ends of the rotation bar. According to this, when all of the first carrier tape wound on the first reel is exhausted, the second carrier tape is transferred. At this time, the first reel is replaced with the second reel. It has become.
　また、回転バーを備えず、定位置に設けられた第１および第２リール保持部にそれぞれ第１および第２テープリールを保持して、第１および第２キャリアテープをオートローディングフィーダに送給する方式のリール保持装置も実用化されている。オートローディングフィーダは、第１キャリアテープをピッチ送りで繰り出して部品供給を行いつつ、第２キャリアテープの先端を繰り出し可能に準備しておき、第１キャリアテープの後端に続いて第２キャリアテープを繰り出す。この後、オペレータは、次の４ステップからなるテープリールの交換作業を行う。すなわち、オペレータは、第１リール保持部から空の第１テープリールを取り外し、第２リール保持部から第２テープリールを取り外し、続いてこの第２テープリールを第１リール保持部に移動させてセットし、第２リール保持部に次の第３テープリールをセットする。 In addition, the first and second tape reels are held in the first and second reel holding portions provided at fixed positions without the rotation bar, and the first and second carrier tapes are fed to the auto loading feeder. A reel holding device of this type has also been put into practical use. The auto-loading feeder prepares the leading end of the second carrier tape so that the first carrier tape is fed out by pitch feeding and supplies the parts, and the second carrier tape follows the rear end of the first carrier tape. To pay out. Thereafter, the operator performs a tape reel replacement operation comprising the following four steps. That is, the operator removes the empty first tape reel from the first reel holding part, removes the second tape reel from the second reel holding part, and then moves the second tape reel to the first reel holding part. Then, the next third tape reel is set on the second reel holding portion.
特開２０１０－２１２６８１号公報JP 2010-212681 A
　ところで、特許文献１の技術例は、回転バーの両端に２個のテープリールを保持して、オートローディングフィーダに対応できる点は好ましい。しかしながら、回転バーの回転方向は不定であり、また、回転バーを所定の回転位置に位置決めするストッパの類も記載されていない。このため、第１リールが第２リールに交替されるときに回転バーが逆方向に回転してしまったり、キャリアテープを送給している途中に回転バーが誤って回転したりする不具合の懸念がある。不具合時には、キャリアテープに過大なテンションや大きな弛みが発生したり、あるいは、２本のキャリアテープが交錯したりして、動作信頼性が低い。 By the way, the technical example of Patent Document 1 is preferable in that two tape reels are held at both ends of the rotating bar so as to be compatible with an auto loading feeder. However, the rotation direction of the rotating bar is indefinite, and no stoppers for positioning the rotating bar at a predetermined rotational position are described. For this reason, when the first reel is replaced with the second reel, the rotating bar may rotate in the reverse direction, or the rotating bar may rotate erroneously while feeding the carrier tape. There is. In the event of a failure, excessive tension or large slack is generated on the carrier tape, or two carrier tapes are interlaced, resulting in low operational reliability.
　また、定位置に設けられた第１および第２リール保持部を有するリール保持装置において、テープリールの交換作業は、前記した４ステップからなるため煩雑であり、手間がかかっていた。さらに、複数のオートローディングフィーダを電子部品装着機の幅方向に列設して使用する場合に、リール保持装置も列設されるので、テープリールを幅方向から着脱する作業が行いにくく、作業性が低下していた。 Further, in the reel holding device having the first and second reel holding portions provided at the fixed positions, the tape reel replacement operation is complicated and time-consuming because of the above four steps. Furthermore, when using multiple autoloading feeders arranged in the width direction of the electronic component mounting machine, the reel holding device is also arranged, making it difficult to attach and detach the tape reel from the width direction. Had fallen.
　本発明は、上記背景技術の問題点に鑑みてなされたものであり、動作信頼性が高く、かつテープリールの交換作業の作業性が良好なリール保持装置を提供することを解決すべき課題とする。 The present invention has been made in view of the above-mentioned problems of the background art, and it is a problem to be solved to provide a reel holding device having high operational reliability and good workability of tape reel replacement work. To do.
　上記課題を解決する本発明のリール保持装置は、第１キャリアテープの後端に続いて第２キャリアテープを繰り出すオートローディングフィーダと組み合わせて使用され、前記第１キャリアテープおよび前記第２キャリアテープをそれぞれ巻回した２個のテープリールを保持するリール保持装置であって、前記２個のテープリールを１個ずつ回転可能かつ交換可能に支承する第１リール支承部および第２リール支承部を両端に有し、長さ方向の中央に回転軸部を有する天秤棒と、前記天秤棒の前記回転軸部を回転可能に支承する支承部材と、前記天秤棒が前記回転軸部を中心にして一方向のみに回転することを許容し、前記オートローディングフィーダに近い近接位置にある前記第１リール支承部を下方から前記オートローディングフィーダから離れた遠方位置に移動可能とし、同時に前記遠方位置にある前記第２リール支承部を上方から前記近接位置に移動可能とし、次に、前記近接位置にある前記第２リール支承部を下方から前記遠方位置に移動可能とし、同時に前記遠方位置にある前記第１リール支承部を上方から前記近接位置に移動可能とする一方向回転機構と、前記天秤棒を特定の回転位置に位置決めして、前記第１リール支承部および前記第２リール支承部を前記近接位置および前記遠方位置のそれぞれに位置決めする位置決め機構と、を備えた。 The reel holding device of the present invention that solves the above problems is used in combination with an autoloading feeder that feeds out the second carrier tape following the rear end of the first carrier tape, and uses the first carrier tape and the second carrier tape. A reel holding device for holding two wound tape reels, each of which has a first reel support portion and a second reel support portion that support the two tape reels in a rotatable and replaceable manner. A balance rod having a rotation shaft portion in the center in the length direction, a support member for rotatably supporting the rotation shaft portion of the balance rod, and the balance rod in only one direction around the rotation shaft portion. The first reel support portion, which is allowed to rotate and is close to the auto loading feeder, moves the auto loading feeder from below. The second reel support portion at the remote position can be moved from above to the proximity position, and then the second reel support portion at the proximity position can be moved from below. A unidirectional rotation mechanism that enables movement to the remote position and simultaneously allows the first reel support portion at the remote position to move from above to the proximity position; and positioning the balance rod at a specific rotation position; And a positioning mechanism for positioning the first reel support portion and the second reel support portion at the close position and the distant position, respectively.
　本発明のリール保持装置において、近接位置にある第１リール支承部の第１テープリールからオートローディングフィーダに送給されていた第１キャリアテープが無くなると、遠方位置にある第２リール支承部の第２テープリールから第２キャリアテープの送給が始まる。オペレータは、この第２キャリアテープが無くなる以前に、天秤棒を一方向に半回転操作する。これにより、空の第１テープリールが近接位置から遠方位置に戻されるとともに、送給中の第２キャリアテープが巻回された第２テープリールが遠方位置から上方を通って近接位置に進められる。このとき、天秤棒は、他方向に回転することはない。また、オペレータが操作を行うとき以外、第１リール支承部および第２リール支承部は、位置決め機構によって遠方位置および近接位置のそれぞれに位置決めされているので、天秤棒が勝手に回転し始めることはない。したがって、キャリアテープに過大なテンションや大きな弛みは発生せず、また、２本のキャリアテープが交錯することも生じないので、動作信頼性が高い。 In the reel holding device of the present invention, when the first carrier tape fed to the auto loading feeder from the first tape reel of the first reel support portion at the close position is lost, the second reel support portion at the remote position is removed. The second carrier tape is fed from the second tape reel. The operator performs a half-turn operation of the balance bar in one direction before the second carrier tape disappears. As a result, the empty first tape reel is returned from the close position to the distant position, and the second tape reel on which the second carrier tape being fed is wound is advanced from the distant position to the close position through the upper side. . At this time, the balance rod does not rotate in the other direction. Moreover, since the first reel support portion and the second reel support portion are positioned at the remote position and the close position by the positioning mechanism, respectively, except when the operator performs an operation, the balance rod does not start to rotate freely. . Therefore, excessive tension and large slack do not occur in the carrier tape, and since the two carrier tapes do not cross each other, the operation reliability is high.
　また、テープリールの交換作業では、遠方位置に戻された第１リール支承部から空の第１テープリールを取り外して、代わりに新しい第３テープリールをセットすればよい。したがって、テープリールの交換作業は、従来の４ステップから２ステップに軽減され、作業性が良好である。 Also, in the tape reel replacement operation, the empty first tape reel may be removed from the first reel support portion returned to the far position, and a new third tape reel may be set instead. Therefore, the tape reel replacement work is reduced from the conventional 4 steps to 2 steps, and the workability is good.

The substrate transfer device 92 includes a transfer unit 925 and a backup unit 926. The transport unit 925 includes a pair of guide rails 921 and 922, a pair of conveyor belts, and the like. The pair of guide rails 921 and 922 crosses the center of the upper surface of the machine base 91 and is assembled to the machine base 91 in parallel with each other. A pair of conveyer belts provided inside the pair of guide rails 921 and 922 facing each other rotate in a state where both edges of the substrate K are placed, and the substrate K is mounted in the central portion of the machine base 91. Carry in and out of position. The backup unit 926 is disposed below the mounting position, and pushes up the substrate K and clamps it in a horizontal posture.
　部品供給装置９３は、機台９１の上面に着脱される略矩形のパレット部材９３１に複数のオートローディングフィーダ８が列設されて構成されている。これに限定されず、オートローディングフィーダ８と他の方式のフィーダとが混在していてもよい。各オートローディングフィーダ８の後方に、それぞれ第１実施形態のリール保持装置１が装着されている。図１において、後述するように、１台のリール保持装置１Ｓの天秤棒２および支承部材３が段取り作業位置に戻されている（図５参照）。また、残りのリール保持装置１の天秤棒２および支承部材３は使用位置に進められている（図２参照）。 The component supply device 93 is configured by arranging a plurality of autoloading feeders 8 on a substantially rectangular pallet member 931 attached to and detached from the upper surface of the machine base 91. The present invention is not limited to this, and the auto loading feeder 8 and other types of feeders may be mixed. The reel holding device 1 according to the first embodiment is mounted behind each auto loading feeder 8. In FIG. 1, as will be described later, the balance rod 2 and the support member 3 of one reel holding device 1S are returned to the setup work position (see FIG. 5). Further, the balance rod 2 and the support member 3 of the remaining reel holding device 1 are advanced to the use position (see FIG. 2).
　部品移載装置９４は、複数のオートローディングフィーダ８から電子部品を吸着採取し、位置決めされた基板Ｋまで搬送して装着する。部品移載装置９４は、Ｘ軸方向およびＹ軸方向に水平移動可能なＸＹロボットタイプの装置である。部品移載装置９４は、ヘッド駆動機構を構成する一対のＹ軸レール９４１、９４２およびＹ軸スライダ９４３、Ｘ軸方向およびＹ軸方向に駆動される装着ヘッド９４４、ノズルツール９４５、吸着ノズル９４６、ならびに基板カメラ９４７などで構成されている。ノズルツール９４５は、装着ヘッド９４４に交換可能に保持される一方で、下側に吸着ノズル９４６を保持している。吸着ノズル９４６は、電子部品を吸着して、基板Ｋに装着する。基板カメラ９４７は、装着ヘッド９４４に設けられており、基板Ｋに付設された位置基準マークを撮像して、基板Ｋの正確な位置を検出する。 The component transfer device 94 sucks and collects electronic components from the plurality of autoloading feeders 8 and transports and mounts them to the positioned substrate K.

The control device 96 is assembled to the machine base 91, and the arrangement position thereof is not particularly limited. The control device 96 controls the component mounting operation according to a previously stored mounting sequence.
　次に、オートローディングフィーダ８の構成について説明する。図２は、第１実施形態のリール保持装置１を右側に示し、オートローディングフィーダ８を左側に示した側面図である。オートローディングフィーダ８は、後端の中間高さ付近にテープ挿入口８１を有し、後端の上部寄りに挿入レバー８２を有している。挿入レバー８２を持ち上げることにより、テープ挿入口８１に第１キャリアテープＴ１および第２キャリアテープＴ２を上下に重ねて挿入できるようになっている。オートローディングフィーダ８のテープ挿入口８１から前端上部に向けて繰り出しレール８３が配設されている。繰り出しレール８３の前端付近の上面に、供給位置８４が設定されている。 Next, the configuration of the auto loading feeder 8 will be described. FIG. 2 is a side view showing the reel holding device 1 of the first embodiment on the right side and the auto loading feeder 8 on the left side. The auto loading feeder 8 has a tape insertion port 81 near the intermediate height of the rear end, and an insertion lever 82 near the upper portion of the rear end. By lifting the insertion lever 82, the first carrier tape T1 and the second carrier tape T2 can be inserted into the tape insertion slot 81 in an overlapping manner. A feed-out rail 83 is disposed from the tape insertion port 81 of the auto loading feeder 8 toward the upper part of the front end. A supply position 84 is set on the upper surface near the front end of the feed rail 83.
　繰り出しレール８３の前方寄りの下部に、前側テープ繰り出し機構８５が配設されている。また、繰り出しレール８３の後方寄りの下部に、後側テープ繰り出し機構８６が配設されている。前側テープ繰り出し機構８５および後側テープ繰り出し機構８６は、それぞれ図略のサーボモータやスプロケットなどで構成される。スプロケットの歯は、繰り出しレール８３に形成された間隙から上方に突出してキャリアテープＴ１、Ｔ２の係合穴に係入する。スプロケットは、サーボモータにより間欠的に回転駆動され、キャリアテープＴ１、Ｔ２を所定ピッチずつ部品供給位置８３へ繰り出す。繰り出しレール８３の部品供給位置８４の手前に、図略のテープ剥離機構が設けられている。 A front tape feed mechanism 85 is disposed at the lower portion of the feed rail 83 near the front. Further, a rear tape feeding mechanism 86 is disposed at a lower portion of the feeding rail 83 near the rear. The front tape feeding mechanism 85 and the rear tape feeding mechanism 86 are each constituted by a servo motor, a sprocket, etc. (not shown). The sprocket teeth protrude upward from the gap formed in the feed rail 83 and engage with the engagement holes of the carrier tapes T1 and T2. The sprocket is intermittently rotated by a servo motor, and feeds the carrier tapes T1 and T2 to the component supply position 83 by a predetermined pitch. A tape peeling mechanism (not shown) is provided in front of the component supply position 84 of the feed rail 83.
　繰り出しレール８３のテープ挿入口８１に近い後部寄りの上側に、テープ制御部８７が設けられている。テープ制御部８７は、下側の第１キャリアテープＴ１の繰り出しを許容し、上側の第２キャリアテープＴ２の先端を待機させる。かつ、テープ制御部８７は、第１キャリアテープＴ１が終端まで繰り出されて無くなると、自動的に第２キャリアテープＴ２の繰り出しを許容する。したがって、第１キャリアテープＴ１の終端と第２キャリアテープＴ２の先端とを接続するスプライシング作業は不要である。 A tape control unit 87 is provided on the upper side of the feeding rail 83 near the rear part near the tape insertion port 81. The tape control unit 87 allows the lower first carrier tape T1 to be fed, and waits the tip of the upper second carrier tape T2. In addition, the tape control unit 87 automatically allows the second carrier tape T2 to be fed when the first carrier tape T1 is fed to the end and disappears. Therefore, the splicing work for connecting the end of the first carrier tape T1 and the tip of the second carrier tape T2 is unnecessary.
　オートローディングフィーダ８の後端下部から下方に向けて、装着バー８８が設けられている。装着バー８８の上下２箇所に、リール保持装置１を装着可能な上側装着部８８１および下側装着部８８２が形成されている。上側装着部８８１および下側装着部８８２は、それぞれ上方に開口する鉤状の２個の取り付け座からなる。図２は、上側装着部８８１に第１実施形態のリール保持装置１が装着された状態を示している。なお、本願出願人は、オートローディングフィーダ８の詳細な構成例を国際公開ＷＯ２０１５／１８１９５８号などに開示している。 A mounting bar 88 is provided downward from the lower end of the rear end of the auto loading feeder 8.

The upper mounting portion 881 and the lower mounting portion 882 are each composed of two hook-shaped mounting seats that open upward. FIG. 2 shows a state where the reel holding device 1 of the first embodiment is mounted on the upper mounting portion 881. The applicant of the present application discloses a detailed configuration example of the autoloading feeder 8 in International Publication No. WO2015 / 181958.
　（２．第１実施形態のリール保持装置１の構成）
　第１実施形態のリール保持装置１は、天秤棒２、支承部材３、一方向回転機構４、位置決め機構５、スライド移動機構６、および装置基部７などで構成されている。天秤棒２は、長い板状の部材である。天秤棒２は、一端に第１リール支承部２１を有し、他端に第２リール支承部２２を有する。第１リール支承部２１および第２リール支承部２２は、それぞれ幅方向（紙面表裏方向）に立設されたセンターピン２３、２４を有する。オペレータは、テープリールＲ１、Ｒ２を幅方向外側から（紙面裏側から）センターピン２３、２４に近付け、テープリールＲ１、Ｒ２の軸孔にセンターピン２３、２４係入させてセットする。センターピン２３、２４は、それぞれ１個のテープリールＲ１、Ｒ２を回転可能かつ交換可能に支承する。天秤棒２は、長さ方向の中央に回転軸部２５を有する。 (2. Configuration of the reel holding device 1 of the first embodiment)
The reel holding device 1 according to the first embodiment includes a balance rod 2, a support member 3, a one-way rotating mechanism 4, a positioning mechanism 5, a slide moving mechanism 6, and an apparatus base 7. The balance rod 2 is a long plate-shaped member. The balance rod 2 has a first reel support portion 21 at one end and a second reel support portion 22 at the other end. The first reel support portion 21 and the second reel support portion 22 have center pins 23 and 24 erected in the width direction (the front and back direction on the paper surface), respectively. The operator brings the tape reels R1 and R2 close to the center pins 23 and 24 from the outside in the width direction (from the back side of the paper), and sets the center pins 23 and 24 in the shaft holes of the tape reels R1 and R2. The center pins 23 and 24 respectively support one tape reel R1 and R2 in a rotatable and replaceable manner. The balance rod 2 has a rotating shaft portion 25 at the center in the length direction.
　支承部材３は、支承部３１およびアーム部３５からなる。支承部３１は、上下に長い部材である。支承部３１の上部は、天秤棒２の回転軸部２５を回転可能に支承する。支承部３１の下部は、アーム部３５に結合されている。アーム部３５は、板状の部材であり、前後方向に長く、かつ前側が下方に湾曲している。アーム部３５の後部は、支承部３１の下部と重ねられ、４本のねじで固定されている。 The support member 3 includes a support part 31 and an arm part 35. The support portion 31 is a member that is long in the vertical direction. The upper part of the support part 31 supports the rotating shaft part 25 of the balance rod 2 rotatably. A lower portion of the support portion 31 is coupled to the arm portion 35. The arm part 35 is a plate-like member, is long in the front-rear direction, and is curved downward on the front side. The rear part of the arm part 35 overlaps with the lower part of the support part 31 and is fixed with four screws.
　一方向回転機構４は、天秤棒２と支承部３１との間に設けられたラチェット機構によって構成されている。図３は、一方向回転機構４および位置決め機構５の構成例を示す部分拡大側面図である。一方向回転機構４は、支承部３１に設けられたラチェットギヤ４１と、天秤棒２に揺動可能に設けられたラチェット爪部材４５とを含んで構成される。ラチェットギヤ４１は、外周にラチェット歯４２を有して、支承部３１に固定されている。 The one-way rotation mechanism 4 is configured by a ratchet mechanism provided between the balance rod 2 and the support portion 31. FIG. 3 is a partially enlarged side view showing a configuration example of the one-way rotation mechanism 4 and the positioning mechanism 5. The one-way rotating mechanism 4 includes a ratchet gear 41 provided on the support portion 31 and a ratchet claw member 45 provided on the balance rod 2 so as to be swingable. The ratchet gear 41 has ratchet teeth 42 on the outer periphery and is fixed to the support portion 31.
　ラチェット爪部材４５は、基端寄りに形成された揺動中心部４６が天秤棒２に支承されて揺動可能となっている。ラチェット爪部材４５の先端の爪部４７は、図略の付勢ばねによってラチェット歯４２に向かい常時付勢されている。爪部４７は、ラチェットギヤ４１の周りを図中の反時計回り（一方向）に回転可能であり、時計回り（他方向）の回転が規制される。ラチェット機構により、天秤棒２の図中の反時計回りの回転のみが許容され（図３の白抜き矢印Ｍ１に示す）、図中の時計回りの回転が規制される。 The ratchet pawl member 45 is swingable with a swing center portion 46 formed near the base end supported by the balance rod 2. The claw portion 47 at the tip of the ratchet claw member 45 is constantly urged toward the ratchet teeth 42 by a biasing spring (not shown). The claw portion 47 can rotate around the ratchet gear 41 in the counterclockwise direction (one direction) in the drawing, and the clockwise rotation (the other direction) is restricted. Only the counterclockwise rotation of the balance rod 2 in the figure is permitted by the ratchet mechanism (indicated by the white arrow M1 in FIG. 3), and the clockwise rotation in the figure is restricted.
　なお、上述した説明と逆に、一方向回転機構４は、天秤棒２に設けられたラチェットギヤ４１と、支承部３１に揺動可能に設けられたラチェット爪部材４５とを含んで構成されてもよい。また、一方向回転機構４として、ラチェット機構以外、例えばワンウェイクラッチを用いることもできる。 Contrary to the above description, the one-way rotating mechanism 4 may include a ratchet gear 41 provided on the balance rod 2 and a ratchet claw member 45 provided on the support 31 so as to be swingable. Good. Moreover, as the one-way rotation mechanism 4, other than a ratchet mechanism, for example, a one-way clutch can be used.
　位置決め機構５は、ラチェットギヤ４１と天秤棒２との間に設けられている。図３に示されるように、ラチェットギヤ４１の外周の１８０°離れた２箇所に、被係止溝５１が形成されている。被係止溝５１の径方向の溝深さは、ラチェット歯４２の凹凸よりも大きい。一方、天秤棒２には、係止ピン５３が進退可能に設けられている。係止ピン５３は、付勢ばね５４によってラチェット歯４２に向かい常時付勢されている。天秤棒２が概ね水平状態にあるとき、係止ピン５３はどちらかの被係止溝５１に進入し、これによって天秤棒２の回転が規制される。被係止溝５１および係止ピン５３は、天秤棒２を特定の回転位置に位置決めする本発明の被係止部および係止部の一実施形態である。 The positioning mechanism 5 is provided between the ratchet gear 41 and the balance rod 2. As shown in FIG. 3, locked grooves 51 are formed at two positions 180 ° apart from the outer periphery of the ratchet gear 41. The groove depth in the radial direction of the locked groove 51 is larger than the unevenness of the ratchet teeth 42. On the other hand, the balance rod 2 is provided with a locking pin 53 so as to advance and retreat. The locking pin 53 is constantly biased toward the ratchet teeth 42 by a biasing spring 54. When the balance rod 2 is in a substantially horizontal state, the locking pin 53 enters one of the locked grooves 51, thereby restricting the rotation of the balance rod 2. The locked groove 51 and the locking pin 53 are an embodiment of the locked portion and the locking portion of the present invention for positioning the balance rod 2 at a specific rotational position.
　天秤棒２を回転操作するとき、オペレータは、係止ピン５３に付属された解除レバー５５を操作して、係止ピン５３を被係止溝５１から退出させる。これにより、位置決め機構５の機能が解除され、天秤棒２の反時計回りの回転が許容される。なお、被係止溝５１は、ラチェットギヤ４１の外周以外、すなわち支承部３１に設けられたラチェットギヤ４１以外の部材に形成されてもよい。 When rotating the balance rod 2, the operator operates the release lever 55 attached to the locking pin 53 to retract the locking pin 53 from the locked groove 51. Thereby, the function of the positioning mechanism 5 is cancelled | released and the counterclockwise rotation of the balance rod 2 is accept | permitted. The locked groove 51 may be formed in a member other than the outer periphery of the ratchet gear 41, that is, a member other than the ratchet gear 41 provided in the support portion 31.
　図２に戻り、装置基部７は、装着バー８８の上側装着部８８１に取り付けられている。これに限定されず、装置基部７は、下側装着部８８２に取り付けられてもよい。装置基部７は、２枚の側板７１が６本の軸部材により結合されて形成されている。装置基部７は、前側の上下２本の軸部材７２、７３が上側装着部８８１の鉤状の２個の取り付け座に上方から係入して取り付けられる。装置基部７の下側には、後方に延びるレール部材６１が固設されている。レール部材６１は、幅方向（紙面表裏方向）に穿孔されて前後方向に延びるスライド孔６２を有する。 2, the device base 7 is attached to the upper mounting portion 881 of the mounting bar 88. Without being limited thereto, the device base 7 may be attached to the lower mounting portion 882. The device base 7 is formed by joining two side plates 71 by six shaft members. The device base 7 is attached by engaging two upper and lower shaft members 72 and 73 on the upper mounting portion 881 with two hook-shaped attachment seats from above. A rail member 61 extending rearward is fixed below the device base 7. The rail member 61 has a slide hole 62 that is perforated in the width direction (the front and back direction in the drawing) and extends in the front-rear direction.
　支承部材３のアーム部３５の前側の下部に、幅方向に延びる２本のガイド軸６３、６４が設けられている。ガイド軸６３、６４は、レール部材６１のスライド孔６２を幅方向に貫通している。ガイド軸６３、６４のスライド孔６２を突き抜けた先端は、拡径されて脱落が防止されている。ガイド軸６３、６４がスライド孔６２の中を移動することにより、支承部材３は前後方向にスライド移動する。 Two guide shafts 63 and 64 extending in the width direction are provided in the lower part of the front side of the arm portion 35 of the support member 3. The guide shafts 63 and 64 penetrate the slide hole 62 of the rail member 61 in the width direction. The tips of the guide shafts 63 and 64 that have passed through the slide hole 62 are expanded in diameter to prevent the guide shafts 63 and 64 from falling off. As the guide shafts 63 and 64 move in the slide hole 62, the support member 3 slides in the front-rear direction.
　図２において、天秤棒２および支承部材３は、オートローディングフィーダ８に近い前方の使用位置に進められている。天秤棒２および支承部材３は、スライド移動されて後方の段取り作業位置に戻される（図５参照）。支承部材３は、使用位置および段取り作業位置に保持されるロック機構を備えることが好ましい。天秤棒２および支承部材３のスライド移動量は、テープリールＲ１、Ｒ２の直径よりも大きめに設定されている。レール部材６１および２本のガイド軸６３、６４は、スライド移動機構６を構成する。 In FIG. 2, the balance rod 2 and the support member 3 are advanced to a use position in front of the auto loading feeder 8. The balance rod 2 and the support member 3 are slid and returned to the rear setup work position (see FIG. 5). The support member 3 preferably includes a lock mechanism that is held in the use position and the setup work position. The sliding movement amounts of the balance rod 2 and the support member 3 are set to be larger than the diameters of the tape reels R1 and R2. The rail member 61 and the two guide shafts 63 and 64 constitute the slide moving mechanism 6.
　（３．第１実施形態のリール保持装置１の使用方法および作用）
　次に、第１実施形態のリール保持装置１の使用方法について説明する。図２は、リール保持装置１からオートローディングフィーダ８に２本のキャリアテープＴ１、Ｔ２が送給される通常時の状態を示している。通常時に、天秤棒２の第１リール支承部２１および第２リール支承部２２の一方は、オートローディングフィーダ８に近い前方の近接位置に配置される。また、第１リール支承部２１および第２リール支承部２２の他方は、オートローディングフィーダ８から離れた後方の遠方位置に配置される。第１リール支承部２１および第２リール支承部２２は、テープリールの交換作業の都度、相互に位置が入れ替わる。図２は、第１リール支承部２１が近接位置に配置され、第２リール支承部２２が遠方位置に配置された状態を例示している。 (3. Usage and operation of the reel holding device 1 of the first embodiment)
Next, the usage method of the reel holding device 1 of 1st Embodiment is demonstrated. FIG. 2 shows a normal state in which two carrier tapes T 1 and T 2 are fed from the reel holding device 1 to the auto loading feeder 8. During normal operation, one of the first reel support portion 21 and the second reel support portion 22 of the balance rod 2 is disposed at a front proximity position near the auto loading feeder 8. Further, the other of the first reel support portion 21 and the second reel support portion 22 is disposed at a far rear position away from the auto loading feeder 8. The positions of the first reel support portion 21 and the second reel support portion 22 are interchanged each time the tape reel is exchanged. FIG. 2 illustrates a state in which the first reel support portion 21 is disposed at the close position and the second reel support portion 22 is disposed at the far position.
　第１リール支承部２１に保持された第１テープリールＲ１から、第１キャリアテープＴ１が送給される。第２リール支承部２２に保持された第２テープリールＲ２から、第２キャリアテープＴ２が送給される。第１キャリアテープＴ１および第２キャリアテープＴ２は、ともにオートローディングフィーダ８のテープ挿入口８１に挿入される。前述したように、下側の第１キャリアテープＴ１は、ピッチ送りで繰り出されて、電子部品が供給される。一方、上側の第２キャリアテープＴ２の先端は、待機状態となっている。電子部品の供給が進められてゆくと、第１キャリアテープＴ１が終端に達して無くなる。すると、自動的に第２キャリアテープＴ２のピッチ送りが開始されて、電子部品の供給が継続され、図４に示される状態となる。 The first carrier tape T1 is fed from the first tape reel R1 held on the first reel support 21. The second carrier tape T2 is fed from the second tape reel R2 held by the second reel support portion 22. Both the first carrier tape T1 and the second carrier tape T2 are inserted into the tape insertion port 81 of the auto loading feeder 8. As described above, the lower first carrier tape T1 is fed out by pitch feed and supplied with electronic components. On the other hand, the tip of the upper second carrier tape T2 is in a standby state. As the supply of electronic components proceeds, the first carrier tape T1 reaches the end and disappears. Then, the pitch feeding of the second carrier tape T2 is automatically started, and the supply of electronic components is continued, resulting in the state shown in FIG.
　図４は、リール保持装置１の遠方位置からオートローディングフィーダ８に第２キャリアテープＴ２のみが送給される一時的な状態を示す側面図である。オペレータは、この第２キャリアテープＴ２が無くなる以前に、時期を見計らってテープリールの交換作業を行うことが好ましい。これにより、オートローディングフィーダ８の部品供給動作は継続される。 FIG. 4 is a side view showing a temporary state in which only the second carrier tape T2 is fed to the auto loading feeder 8 from a remote position of the reel holding device 1. It is preferable for the operator to replace the tape reel at an appropriate time before the second carrier tape T2 is used up. Thereby, the parts supply operation of the auto loading feeder 8 is continued.
　テープリールの交換作業において、オペレータは、図４および図５の白抜き矢印Ｍ２に示されるように、スライド移動機構６を用いて天秤棒２および支承部材３を使用位置から段取り作業位置にスライド移動させる。このとき、第２キャリアテープＴ２に多少のテンションが発生するが、テンションに応じて第２テープリールＲ２は自動的に回転する。図５は、段取り作業位置で天秤棒２を反時計回りに（一方向に）半回転させる直前の状態を示す側面図である。 In the tape reel replacement operation, the operator slides the balance rod 2 and the support member 3 from the use position to the set-up operation position using the slide movement mechanism 6 as indicated by the white arrow M2 in FIGS. . At this time, some tension is generated in the second carrier tape T2, but the second tape reel R2 automatically rotates in accordance with the tension. FIG. 5 is a side view showing a state immediately before the balance rod 2 is rotated halfway counterclockwise (in one direction) at the setup work position.
　オペレータは、次に、解除レバー５５を操作して係止ピン５３を一方の被係止溝５１から退出させながら、白抜き矢印Ｍ３に示されるように天秤棒２を反時計回りに回転操作する。天秤棒２が半回転すると、係止ピン５３は、付勢ばね５４の作用によって他方の被係止溝５１に自動的に係入する。これにより、天秤棒２は、再び水平状態に位置決めされる。 Next, the operator operates the release lever 55 to rotate the balance rod 2 counterclockwise as indicated by the white arrow M3 while retracting the locking pin 53 from one of the locked grooves 51. When the balance rod 2 rotates halfway, the locking pin 53 is automatically engaged with the other locked groove 51 by the action of the biasing spring 54. Thereby, the balance rod 2 is positioned in a horizontal state again.
　天秤棒２の回転操作により、近接位置にある第１リール支承部２１を下方から遠方位置に移動できる。これにより、空の第１テープリールＲ１は、近接位置から下方を通って遠方位置に戻される。同時に、遠方位置にある第２リール支承部２２を上方から近接位置に移動できる。これにより、送給中の第２キャリアテープＴ２が巻回された第２テープリールＲ２は、遠方位置から上方を通って近接位置に進められる。このとき、第２キャリアテープＴ２に過大な弛みが発生しないように、オペレータは、適宜第２テープリールＲ２を反転操作することが好ましい。 Rotation operation of the balance rod 2 can move the first reel support portion 21 in the close position from the lower position to the far position. Thus, the empty first tape reel R1 is returned from the proximity position to the far position through the lower position. At the same time, the second reel support portion 22 located at the far position can be moved from above to the close position. Accordingly, the second tape reel R2 around which the second carrier tape T2 being fed is wound is advanced from the far position to the close position through the upper side. At this time, it is preferable for the operator to appropriately reverse the second tape reel R2 so that excessive slack does not occur in the second carrier tape T2.
　オペレータは、遠方位置に戻された第１リール支承部２１から空の第１テープリールＲ１を取り外して、代わりに新しい第３テープリールＲ３をセットする。次に、オペレータは、図６の白抜き矢印Ｍ４に示されるように、支承部材３および天秤棒２を段取り作業位置から使用位置にスライド移動させる。このとき、第２キャリアテープＴ２に過大な弛みが発生しないように、オペレータは、適宜第２テープリールＲ２を反転操作することが好ましい。図６は、天秤棒２および支承部材３を使用位置に進めた直後の状態を示す側面図である。 The operator removes the empty first tape reel R1 from the first reel support portion 21 returned to the far position, and sets a new third tape reel R3 instead. Next, the operator slides the support member 3 and the balance rod 2 from the setup work position to the use position as indicated by the white arrow M4 in FIG. At this time, it is preferable for the operator to appropriately reverse the second tape reel R2 so that excessive slack does not occur in the second carrier tape T2. FIG. 6 is a side view showing a state immediately after the balance rod 2 and the support member 3 are advanced to the use position.
　次に、オペレータは、第１リール支承部２１の第３テープリールＲ３から第３キャリアテープＴ３の先端を引き出して、オートローディングフィーダ８のテープ挿入口８１に挿入する。これで、テープリールの交換作業が終了し、図２に示された通常時の状態に戻る。テープリールの交換作業の間、第２キャリアテープＴ２の送給、およびオートローディングフィーダ８の部品供給動作は、継続されている。 Next, the operator pulls out the tip of the third carrier tape T3 from the third tape reel R3 of the first reel support 21 and inserts it into the tape insertion port 81 of the auto loading feeder 8. This completes the tape reel replacement operation and returns to the normal state shown in FIG. During the tape reel replacement operation, the feeding of the second carrier tape T2 and the parts supplying operation of the auto loading feeder 8 are continued.
　その後、近接位置の第２リール支承部２２の第２テープリールＲ２から送給されている第２キャリアテープＴ２が終端まで使用されて無くなると、オペレータは、天秤棒２を再びスライド移動および回転操作してテープリールの交換作業を再度行う。これにより、空の第２テープリールＲ２は、近接位置から下方を通って遠方位置に戻される。同時に、送給中の第３キャリアテープＴ３が巻回された第３テープリールＲ３は、遠方位置から上方を通って近接位置に進められる。以降、テープリールの交換作業が適宜繰り返されることにより、オートローディングフィーダ８の部品供給動作は継続される。 After that, when the second carrier tape T2 fed from the second tape reel R2 of the second reel support 22 at the close position is used up to the end, the operator slides and rotates the balance rod 2 again. Then replace the tape reel again. Thereby, the empty second tape reel R2 is returned from the proximity position to the far position through the lower position. At the same time, the third tape reel R3 around which the third carrier tape T3 being fed is wound is advanced from the far position to the close position through the upper side. Thereafter, the parts supply operation of the auto loading feeder 8 is continued by appropriately repeating the tape reel replacement operation.
　次に、第１実施形態のリール保持装置１の作用について、参考形態と対比して説明する。図７は、参考形態のリール保持装置１Ｘを右側に示し、オートローディングフィーダ８を左側に示した側面図である。参考形態のリール保持装置１Ｘは、スライド移動機構６を備えるが、天秤棒２を備えない。参考形態のリール保持装置１Ｘは、スライド移動可能な支承部材３Ｘ上の定位置に第１リール支承部３７および第２リール支承部３８が設けられている。 Next, the operation of the reel holding device 1 of the first embodiment will be described in comparison with the reference embodiment. FIG. 7 is a side view showing the reel holding device 1X of the reference form on the right side and showing the auto loading feeder 8 on the left side. The reel holding device 1X of the reference form includes the slide moving mechanism 6, but does not include the balance rod 2. The reel holding device 1X of the reference form is provided with a first reel support portion 37 and a second reel support portion 38 at fixed positions on a slide member 3X that can be slid.
　参考形態のリール保持装置１Ｘにおいてテープリールの交換作業を行うとき、次の４ステップＳ１）～Ｓ４）が必要となる（図７の破線矢印Ｓ１～Ｓ４参照）。
Ｓ１）第１リール支承部３７から空の第１テープリールＲ１を取り外す。
Ｓ２）第２リール支承部３８から、第２キャリアテープＴ２を送給中の第２テープリールＲ２を取り外す。
Ｓ３）取り外した第２テープリールＲ２を、第１リール支承部３７に移動してセットする。
Ｓ４）第２リール支承部３８に新しい第３テープリールＲ３をセットする。 When the tape reel replacement operation is performed in the reel holding device 1X of the reference form, the following four steps S1) to S4) are required (see broken line arrows S1 to S4 in FIG. 7).
S1) Remove the empty first tape reel R1 from the first reel support 37.
S2) The second tape reel R2 that is feeding the second carrier tape T2 is removed from the second reel support 38.
S3) The removed second tape reel R2 is moved to the first reel support portion 37 and set.
S4) A new third tape reel R3 is set on the second reel support 38.
　これに対して、第１実施形態のリール保持装置１では、遠方位置の第１リール支承部２１から空の第１テープリールＲ１を取り外して、代わりに新しい第３テープリールＲ３をセットする２ステップで済む。 On the other hand, in the reel holding device 1 of the first embodiment, two steps of removing the empty first tape reel R1 from the first reel support portion 21 at the remote position and setting a new third tape reel R3 instead. Just do it.
　さらに、リール保持装置１Ｓ（図１参照）の段取り作業位置に戻された天秤棒２の遠方位置において、第１リール支承部２１は、列設された他のリール保持装置１よりも後方に位置する。このため、第１リール支承部２１で行われるテープリールの交換作業は、隣接した他のリール保持装置１に阻害されない。換言すると、第１リール支承部２１から幅方向外側に第１テープリールＲ１を取り外す作業、および、第１リール支承部２１に幅方向外側から第３テープリールＲ３をセットする作業は、ともに容易である。
（４．第１実施形態のリール保持装置１の態様および効果）
　第１実施形態のリール保持装置１は、第１キャリアテープＴ１の後端に続いて第２キャリアテープＴ２を繰り出すオートローディングフィーダ８と組み合わせて使用され、第１キャリアテープＴ１および第２キャリアテープＴ２をそれぞれ巻回した２個のテープリールＲ１、Ｒ２を保持するリール保持装置１であって、２個のテープリールＲ１、Ｒ２を１個ずつ回転可能かつ交換可能に支承する第１リール支承部２１および第２リール支承部２２を両端に有し、長さ方向の中央に回転軸部２５を有する天秤棒２と、天秤棒２の回転軸部２５を回転可能に支承する支承部材３と、天秤棒２が回転軸部２５を中心にして一方向のみに回転することを許容し、オートローディングフィーダ８に近い近接位置にある第１リール支承部２１を下方からオートローディングフィーダ８から離れた遠方位置に移動可能とし、同時に遠方位置にある第２リール支承部２２を上方から近接位置に移動可能とし、次に、近接位置にある第２リール支承部２２を下方から遠方位置に移動可能とし、同時に遠方位置にある第１リール支承部２１を上方から近接位置に移動可能とする一方向回転機構４と、天秤棒２を特定の回転位置に位置決めして、第１リール支承部２１および第２リール支承部２２を近接位置および遠方位置のそれぞれに位置決めする位置決め機構５と、を備えた。 Further, the first reel support portion 21 is located rearward of the other reel holding devices 1 arranged in the far position of the balance rod 2 returned to the setup work position of the reel holding device 1S (see FIG. 1). . For this reason, the exchange operation of the tape reel performed by the first reel support portion 21 is not hindered by other adjacent reel holding devices 1. In other words, both the operation of removing the first tape reel R1 from the first reel support portion 21 outward in the width direction and the operation of setting the third tape reel R3 from the width direction outer side to the first reel support portion 21 are both easy. is there.
(4. Aspects and effects of the reel holding device 1 of the first embodiment)

It is possible to move to a distant position away from the loading feeder 8, and at the same time, the second reel support portion 22 at the distant position can be moved from above to the close position, and then the second reel support portion 22 at the close position is moved downward. The unidirectional rotating mechanism 4 that enables the first reel support portion 21 that can be moved from the upper position to the far position and the first reel support portion 21 that is located at the far position can be moved from the upper position to the close position, and the balance rod 2 is positioned at a specific rotating position, And a positioning mechanism 5 for positioning the reel support portion 21 and the second reel support portion 22 in the close position and the distant position, respectively.
　第１実施形態のリール保持装置１において、近接位置にある第１リール支承部２１の第１テープリールＲ１からオートローディングフィーダ８に送給されていた第１キャリアテープＴ１が無くなると、遠方位置にある第２リール支承部２２の第２テープリールＲ２から第２キャリアテープＴ２の送給が始まる。オペレータは、この第２キャリアテープＴ２が無くなる以前に、天秤棒２を一方向に半回転操作する。これにより、空の第１テープリールＲ１が近接位置から遠方位置に戻されるとともに、送給中の第２キャリアテープＴ２が巻回された第２テープリールＲ２が遠方位置から上方を通って近接位置に進められる。このとき、天秤棒２は、他方向に回転することはない。また、オペレータが操作を行うとき以外、第１リール支承部２１および第２リール支承部２２は、位置決め機構５によって遠方位置および近接位置のそれぞれに位置決めされているので、天秤棒２が勝手に回転し始めることはない。したがって、キャリアテープＴ１、Ｔ２に過大なテンションや大きな弛みは発生せず、また、２本のキャリアテープＴ１、Ｔ２が交錯することも生じないので、動作信頼性が高い。 In the reel holding device 1 according to the first embodiment, when the first carrier tape T1 fed from the first tape reel R1 of the first reel support portion 21 in the close position to the autoloading feeder 8 disappears, the reel holding apparatus 1 moves to the far position. The feeding of the second carrier tape T2 starts from the second tape reel R2 of a certain second reel support portion 22. The operator operates the balance bar 2 halfway in one direction before the second carrier tape T2 disappears. As a result, the empty first tape reel R1 is returned from the close position to the distant position, and the second tape reel R2 around which the second carrier tape T2 being fed is wound passes from above the distant position to the close position. Proceed to At this time, the balance rod 2 does not rotate in the other direction. Further, except when the operator performs the operation, the first reel support portion 21 and the second reel support portion 22 are positioned at the remote position and the close position by the positioning mechanism 5, respectively, so that the balance rod 2 rotates freely. Never start. Therefore, excessive tension and large slack do not occur on the carrier tapes T1 and T2, and the two carrier tapes T1 and T2 do not cross each other, so that the operation reliability is high.
　また、テープリールの交換作業では、遠方位置に戻された第１リール支承部２１から空の第１テープリールＲ１を取り外して、代わりに新しい第３テープリールＲ３をセットすればよい。したがって、テープリールの交換作業は、従来の４ステップから２ステップに軽減され、作業性が良好である。 Also, in the tape reel replacement operation, the empty first tape reel R1 may be removed from the first reel support portion 21 returned to the far position, and a new third tape reel R3 may be set instead. Therefore, the tape reel replacement work is reduced from the conventional 4 steps to 2 steps, and the workability is good.
　さらに、一方向回転機構４は、支承部材３に設けられたラチェットギヤ４１と、天秤棒２に揺動可能に設けられ、ラチェットギヤ４１との間における一方向への相対回転を許容するとともに他方向への相対回転を規制するラチェット爪部材４５と、を含んだラチェット機構とされている。これによれば、天秤棒２の他方向への回転を確実に防止でき、動作信頼性が高い。 Further, the one-way rotating mechanism 4 is swingably provided on the ratchet gear 41 provided on the support member 3 and the balance rod 2 and allows relative rotation in one direction between the ratchet gear 41 and the other direction. The ratchet mechanism includes a ratchet pawl member 45 for restricting relative rotation to the ratchet. According to this, rotation of the balance rod 2 in the other direction can be reliably prevented, and operation reliability is high.
　さらに、位置決め機構５は、ラチェットギヤ４１に形成された被係止部（被係止溝５１）と、天秤棒２に設けられて被係止部を係止する係止部（係止ピン５３）とを含む。これによれば、天秤棒２が勝手に回転し始めることを確実に防止でき、動作信頼性が高い。また、一方向回転機構４を構成するラチェットギヤ４１が位置決め機構５に兼用されるので、構成部材点数が削減されて、コストが抑制される。 Furthermore, the positioning mechanism 5 includes a locked portion (locked groove 51) formed in the ratchet gear 41 and a locking portion (locking pin 53) provided on the balance rod 2 to lock the locked portion. Including. According to this, it can prevent reliably that the balance rod 2 begins to rotate arbitrarily, and operation | movement reliability is high. Further, since the ratchet gear 41 constituting the one-way rotating mechanism 4 is also used as the positioning mechanism 5, the number of constituent members is reduced and the cost is suppressed.
　さらに、第１実施形態のリール保持装置１は、オートローディングフィーダ８に近い使用位置と、オートローディングフィーダ８から離れた段取り作業位置との間で支承部材３を移動可能とするスライド移動機構６をさらに備えている。これによれば、オペレータは、テープリールの交換作業を段取り作業位置で行えて、隣接した他のリール保持装置１に阻害されない。したがって、テープリールの交換作業の作業性は、さらに一層良好となる。 Furthermore, the reel holding device 1 according to the first embodiment includes a slide moving mechanism 6 that allows the support member 3 to move between a use position close to the auto loading feeder 8 and a setup work position away from the auto loading feeder 8. It has more. According to this, the operator can perform the tape reel replacement work at the setup work position and is not obstructed by the other adjacent reel holding device 1. Therefore, the workability of the tape reel replacement work is further improved.
　（５．第２実施形態のリール保持装置１Ａ）
　次に、第２実施形態のリール保持装置１Ａについて、第１実施形態と異なる点を主に説明する。図８は、第２実施形態のリール保持装置１Ａを左側に示し、オートローディングフィーダ８を右側に示した側面図である。第２実施形態のリール保持装置１Ａは、天秤棒２Ａの構造が第１実施形態と異なり、他の部分は第１実施形態と同じである。第２実施形態の天秤棒２Ａは、中央部材２６、第１腕部材２７、および第２腕部材２８を含んで構成されている。図９は、通常の使用における第２実施形態の天秤棒２Ａの中央部材２６およびその周りの状態を示した部分拡大側面図である。 (5. Reel holding device 1A of the second embodiment)
Next, the difference between the reel holding device 1A of the second embodiment and the first embodiment will be mainly described. FIG. 8 is a side view showing the reel holding device 1 </ b> A of the second embodiment on the left side and the auto loading feeder 8 on the right side. The reel holding device 1A of the second embodiment is different from the first embodiment in the structure of the balance rod 2A, and the other parts are the same as those in the first embodiment. The balance rod 2A of the second embodiment includes a central member 26, a first arm member 27, and a second arm member 28. FIG. 9 is a partially enlarged side view showing the central member 26 of the balance rod 2A of the second embodiment and the state around it in normal use.
　中央部材２６は、略環状の部材であり、その外周面が回転軸部２５の機能を果たしている。詳述すると、支承部３１の上部に形成された支承孔３２の内周面に、中央部材２６の外周面（回転軸部２５）が回転可能に支承されている。中央部材２６と支承部３１との間には、第１実施形態で説明した一方向回転機構４および位置決め機構５が設けられている。これにより、中央部材２６は、図８および図９の白抜き矢印Ｍ５に示される時計回りの回転のみが許容され、かつ特定の回転位置に位置決めされる。 The central member 26 is a substantially annular member, and the outer peripheral surface thereof functions as the rotating shaft portion 25. More specifically, the outer peripheral surface (rotating shaft portion 25) of the central member 26 is rotatably supported on the inner peripheral surface of the support hole 32 formed in the upper portion of the support portion 31. Between the central member 26 and the support portion 31, the one-way rotation mechanism 4 and the positioning mechanism 5 described in the first embodiment are provided. As a result, the central member 26 is only allowed to rotate clockwise as indicated by the outlined arrow M5 in FIGS. 8 and 9, and is positioned at a specific rotational position.
　第１腕部材２７および第２腕部材２８は、第１実施形態の天秤棒２の半分程度の長さを有する板状の部材である。第１腕部材２７は、一端に第１リール支承部２１およびセンターピン２３を有する（図８に示す）。また、第１腕部材２７は、他端に円筒軸２７１、および被係止部材２７２を有する（図９に示す）。円筒軸２７１は、幅方向(図９の紙面表裏方向)に延び、中央部材２６の内周面に回転可能に支承されている。これにより、第１腕部材２７は、中央部材２６に連結される。かつ、第１腕部材２７は、円筒軸２７１を中心にして、第１リール支承部２１が上下方向に揺動可能となっている。被係止部材２７２は、円筒軸２７１の端面に配設されており、Ｖ字形状にへこんだ被係止凹部２７３をもつ。 The first arm member 27 and the second arm member 28 are plate-like members having a length about half that of the balance rod 2 of the first embodiment. The first arm member 27 has a first reel support portion 21 and a center pin 23 at one end (shown in FIG. 8). The first arm member 27 has a cylindrical shaft 271 and a locked member 272 at the other end (shown in FIG. 9). The cylindrical shaft 271 extends in the width direction (the front and back direction in FIG. 9) and is rotatably supported on the inner peripheral surface of the central member 26. As a result, the first arm member 27 is connected to the central member 26. The first arm member 27 is configured such that the first reel support portion 21 can swing in the vertical direction about the cylindrical shaft 271. The locked member 272 is disposed on the end surface of the cylindrical shaft 271 and has a locked recess 273 that is recessed in a V shape.
　一方、中央部材２６は、側面に第１係止部材２６１を有する。第１係止部材２６１は、一端に揺動中心部２６２をもち、他端にはＶ字形状に突出した係止部２６３をもつ。揺動中心部２６２が中央部材２６に支承されることで、第１係止部材２６１は揺動可能となっている。第１係止部材２６１は、図略の付勢ばねによって図９の時計回りに付勢されている。これにより、係止部２６３は、通常の使用時に第１腕部材２７の被係止凹部２７３を係止し、第１腕部材２７の揺動を規制する。 On the other hand, the central member 26 has a first locking member 261 on the side surface. The first locking member 261 has a rocking center portion 262 at one end and a locking portion 263 protruding in a V shape at the other end. The first locking member 261 can swing because the swing center portion 262 is supported by the center member 26. The first locking member 261 is biased clockwise in FIG. 9 by an unillustrated biasing spring. Thus, the locking portion 263 locks the locked recess 273 of the first arm member 27 during normal use, and restricts the swinging of the first arm member 27.
　第１腕部材２７と同様に、第２腕部材２８は、一端に第２リール支承部２２およびセンターピン２４を有する（図８に示す）。また、第２腕部材２８は、他端に軸２８１、および被係止部材２８２を有する（図９に示す）。軸２８１は、幅方向(図９の紙面表裏方向)に延び、第１腕部材２７の円筒軸２７１の内周側に回転可能に支承されている。これにより、第２腕部材２８は、中央部材２６に連結される。かつ、第２腕部材２８は、軸２８１を中心にして、第２リール支承部２２が上下方向に揺動可能となっている。被係止部材２８２は、軸２８１の円筒軸２７１を突き抜けた端面に配設されており、Ｖ字形状にへこんだ被係止凹部２８３をもつ。 Similarly to the first arm member 27, the second arm member 28 has a second reel support portion 22 and a center pin 24 at one end (shown in FIG. 8). Further, the second arm member 28 has a shaft 281 and a locked member 282 at the other end (shown in FIG. 9). The shaft 281 extends in the width direction (the front and back direction in FIG. 9) and is rotatably supported on the inner peripheral side of the cylindrical shaft 271 of the first arm member 27. As a result, the second arm member 28 is connected to the central member 26. The second arm member 28 has the second reel support portion 22 swingable in the vertical direction about the shaft 281. The locked member 282 is disposed on the end surface of the shaft 281 that penetrates the cylindrical shaft 271 and has a locked recess 283 that is recessed in a V shape.
　一方、中央部材２６は、側面の第１係止部材２６１の対称位置に第２係止部材２６５を有する。第２係止部材２６５は、一端に揺動中心部２６６をもち、他端にはＶ字形状に突出した係止部２６７をもつ。揺動中心部２６６が中央部材２６に支承されることで、第２係止部材２６５は揺動可能となっている。第２係止部材２６５は、図略の付勢ばねによって図９の時計回りに付勢されている。これにより、係止部２６７は、通常の使用時に第２腕部材２８の被係止凹部２８３を係止し、第２腕部材２８の揺動を規制する。 On the other hand, the central member 26 has a second locking member 265 at the symmetrical position of the first locking member 261 on the side surface. The second locking member 265 has a swinging central portion 266 at one end and a locking portion 267 protruding in a V shape at the other end. The second locking member 265 can swing because the swinging center portion 266 is supported by the central member 26. The second locking member 265 is biased clockwise in FIG. 9 by an unillustrated biasing spring. Thus, the locking portion 267 locks the locked recess 283 of the second arm member 28 during normal use and restricts the swinging of the second arm member 28.
　第１リール支承部２１および第２リール支承部２２がともにテープリールＲ１、Ｒ２を支承している場合、オペレータは、図８および図９に示される通常の使用状態を選択する。通常の使用状態において、第１腕部材２７および第２腕部材２８は、揺動が規制されて、一直線状に水平に並ぶ。これにより、第１リール支承部２１および第２リール支承部２２は、遠方位置および近接位置のそれぞれに位置決めされる。この場合の使用方法および作用は、第１実施形態と同じであるので、説明は省略する。 When both the first reel support part 21 and the second reel support part 22 support the tape reels R1 and R2, the operator selects the normal use state shown in FIGS. In a normal use state, the first arm member 27 and the second arm member 28 are restricted from swinging and are aligned horizontally in a straight line. Thereby, the 1st reel support part 21 and the 2nd reel support part 22 are positioned in a distant position and a proximity position, respectively. Since the method of use and the action in this case are the same as those in the first embodiment, description thereof will be omitted.
　第１リール支承部２１のみが第１テープリールＲ１を支承している場合、オペレータは、図１０に示される１テープリールのみの使用状態を選択する。図１０は、１テープリールのみの使用における第２実施形態の天秤棒２Ａの中央部材２６およびその周りの状態を示した部分拡大側面図である。第１および第２実施形態のリール保持装置１、１Ａは、従来型のフィーダと組み合わせての使用が可能であり、このとき１個のテープリールＲ１を保持できればよい。 When only the first reel support portion 21 supports the first tape reel R1, the operator selects the use state of only one tape reel shown in FIG. FIG. 10 is a partially enlarged side view showing the central member 26 of the balance rod 2A of the second embodiment and the surroundings thereof when only one tape reel is used. The reel holding devices 1 and 1A of the first and second embodiments can be used in combination with a conventional feeder, and at this time, it is only necessary to hold one tape reel R1.
　この場合、図１０に示されるように、オペレータは、付勢ばねに抗して第２係止部材２６５を上方に揺動操作し、係止部２６７による被係止凹部２８３の係止を解除する。これにより、第２腕部材２８の揺動が許容されるので、オペレータは、第２腕部材２８を下方向に揺動操作して、第２リール支承部２２をスライド移動機構６の後端に接近させる（図１０の白抜き矢印Ｍ６参照）。 In this case, as shown in FIG. 10, the operator swings the second locking member 265 upward against the urging spring, and releases the locking of the locked recess 283 by the locking portion 267. To do. As a result, the second arm member 28 is allowed to swing, so that the operator swings the second arm member 28 downward to place the second reel support portion 22 at the rear end of the slide moving mechanism 6. Approach (see white arrow M6 in FIG. 10).
　なお、第２リール支承部２２のみに第２テープリールＲ２を支承させて使用することも可能である。この場合、オペレータは、まず、図８および図９に示される状態から天秤棒２Ａを半回転させて、近接位置に第２リール支承部２２を進める。オペレータは、次に、上側まで回転した第１係止部材２６１を上方に揺動操作し、係止部２６３による被係止凹部２７３の係止を解除して、遠方位置の第１腕部材２７を下方向に揺動操作する。 It should be noted that the second tape reel R2 can be supported only on the second reel support portion 22 and used. In this case, the operator first advances the second reel support portion 22 to the close position by half-turning the balance rod 2A from the state shown in FIGS. Next, the operator swings the first locking member 261 rotated to the upper side upward to release the locking of the locked recess 273 by the locking portion 263, and the first arm member 27 at the far position is released. Swing down.
　第２実施形態のリール保持装置１Ａにおいて、天秤棒２Ａは、回転軸部２５を有する中央部材２６と、一端に第１リール支承部２１を有して他端が中央部材２６に揺動可能に連結された第１腕部材２７と、一端に第２リール支承部２２を有して他端が中央部材２６に揺動可能に連結された第２腕部材２８と、を含み、第１リール支承部２１および第２リール支承部２２がともにテープリールＲ１、Ｒ２を支承している場合に、第１腕部材２７および第２腕部材２８は、第１リール支承部２１および第２リール支承部２２が近接位置および遠方位置のそれぞれに位置決めされる方向に揺動され、第１リール支承部２１のみが第１テープリールＲ１を支承している場合に、第１腕部材２７は、第１リール支承部２１が近接位置に位置決めされる方向に揺動され、第２腕部材２８は、下方向または上方向に揺動される。 In the reel holding device 1A of the second embodiment, the balance rod 2A includes a central member 26 having a rotating shaft portion 25, a first reel support portion 21 at one end, and the other end swingably connected to the central member 26. A first arm support member 27 and a second arm member 28 having a second reel support portion 22 at one end and a swingable connection to the central member 26 at the other end. 21 and the second reel support portion 22 both support the tape reels R1 and R2, the first arm member 27 and the second arm member 28 have the first reel support portion 21 and the second reel support portion 22 respectively. When the first arm member 27 is swung in the directions positioned at the close position and the distant position and only the first reel support portion 21 supports the first tape reel R1, the first arm member 27 becomes the first reel support portion. 21 is positioned in the proximity position Is swung toward the second arm member 28 is swung downward or upward.
　これによれば、１テープリールのみの使用時に、使用していない第２腕部材２８をコンパクトに畳み込むことができる。したがって、隣接した他のリール保持装置１、１Ａにおけるテープの交換作業の作業性がさらに一層良好となる。また、第２腕部材２８が突起物とならないので、安全性に優れる。 According to this, when only one tape reel is used, the unused second arm member 28 can be compactly folded. Therefore, the workability of the tape replacement work in the other adjacent reel holding devices 1 and 1A is further improved. Moreover, since the 2nd arm member 28 does not become a protrusion, it is excellent in safety.
　（６．実施形態の応用および変形）
　なお、第１および第２実施形態では、天秤棒２、２Ａを水平状態にして用いるが、これに限定されず、傾斜を設けて用いるようにしてもよい。また、一方向回転機構４および位置決め機構５については、第１実施形態で説明した構成以外にも、公知の様々な構造を採用できる。本発明は、その他にも様々な応用や変形が可能である。 (6. Application and modification of embodiment)
