Description

本発明は、リーダーテープのテープ繰り出し端に先導ピースのピンが連結された単リール型テープカートリッジの製造方法に関する。ここでのリーダーテープは、データを記録する磁気テープの繰り出し端に連結されており、先導ピースは、リーダーテープを介して磁気テープをテープドライブ側へ引き出し操作するためのものである。   The present invention relates to a method for manufacturing a single reel type tape cartridge in which a pin of a leading piece is connected to a tape feeding end of a leader tape. The leader tape here is connected to the feeding end of the magnetic tape for recording data, and the leading piece is for pulling out the magnetic tape to the tape drive side via the leader tape.

特許文献1〜3には、リーダーテープの繰り出し端に設けた反転部を、先導ピースのピンに巻き付け反転してリーダーテープの繰り出し端の基部に重ねた状態で、超音波溶着装置のアンビル(受け座)の上面に基部を載置し、超音波溶着装置の溶着ホーンを反転部の上側から押し付けて超音波振動することにより、反転部と基部とを摩擦熱で溶着する形式が開示されている。   In Patent Documents 1 to 3, an anvil (receiver) of an ultrasonic welding apparatus is provided in a state in which a reversing portion provided at a leader tape feeding end is wound around a lead piece pin and reversed and overlapped with a base of a leader tape feeding end. The base is placed on the upper surface of the seat), and the welding horn of the ultrasonic welding apparatus is pressed from the upper side of the reversing part and ultrasonically vibrated, whereby the reversing part and the base are welded by frictional heat. .

特開2001−357658号公報(段落番号0022、図1)Japanese Patent Laid-Open No. 2001-357658 (paragraph number 0022, FIG. 1) 特開2002−124057号公報(段落番号0008、図4)JP 2002-124057 (paragraph number 0008, FIG. 4) 特開2002−324377号公報(段落番号0017、図3−4)JP 2002-324377 A (paragraph number 0017, FIG. 3-4)

超音波溶着の際に、リーダーテープの繰り出し端の基部がアンビル上で滑ると、反転部と基部とが十分に擦れ合わず、不完全な溶着状態になる。このため、アンビルの上面を粗面に形成し、アンビルの上面とリーダーテープの基部との間の摩擦抵抗を大きくして、基部がアンビル上で滑ることを防いでいた。   During ultrasonic welding, if the base portion of the leader tape feed end slides on the anvil, the inversion portion and the base portion do not rub against each other sufficiently, resulting in an incomplete welding state. For this reason, the upper surface of the anvil is formed into a rough surface, and the frictional resistance between the upper surface of the anvil and the base portion of the leader tape is increased to prevent the base portion from sliding on the anvil.

ところが、量産に伴なってアンビルが次第に磨耗して平滑化するため、基部がアンビル上で滑りやすくなるところに問題があった。また、アンビルと基部との間の摩擦抵抗は、溶着ホーンの下降位置や押圧力、あるいはリーダーテープの厚み寸法のばらつきなどによって変化するため、安定した溶着状態が得られなかった。   However, since the anvil is gradually worn and smoothed with mass production, there is a problem in that the base becomes slippery on the anvil. In addition, since the frictional resistance between the anvil and the base changes depending on the lowered position of the welding horn, the pressing force, or the variation in the thickness dimension of the leader tape, a stable welding state cannot be obtained.

そこで本発明の目的は、超音波溶着装置のアンビルと、リーダーテープの繰り出し端の基部との間の摩擦抵抗に関係なく、アンビルに基部をしっかりと固定できる単リール型テープカートリッジの製造方法を提供することにある。   SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a method for manufacturing a single reel type tape cartridge that can firmly fix the base to the anvil regardless of the frictional resistance between the anvil of the ultrasonic welding apparatus and the base of the leader tape feeding end. There is to do.

本発明に係る単リール型テープカートリッジの製造方法は、図1および図4に示すごとく、リーダーテープ10の繰り出し端に設けた反転部24を、先導ピース11のピン12に巻き付け反転してリーダーテープ10の繰り出し端の基部23に重ねた状態で、基部23をアンビル26の上面に載置し、溶着ホーン27を反転部24の上側から押し付けて、基部23と反転部24とを超音波溶着するにある。   As shown in FIGS. 1 and 4, the manufacturing method of the single reel type tape cartridge according to the present invention winds and reverses the reversing portion 24 provided at the feeding end of the leader tape 10 around the pin 12 of the leading piece 11 to reverse the leader tape. The base 23 is placed on the upper surface of the anvil 26 while being superposed on the base 23 at the extending end 10, and the welding horn 27 is pressed from the upper side of the reversing unit 24 to ultrasonically weld the base 23 and the reversing unit 24. It is in.

そのうえで、アンビル26の上面には、少なくとも前記基部23を受け止める平面状の部分26aに多数の吸引孔28を分散状に形成しておき、アンビル26の上面に基部23を載置して、基部23を受け止める部分26aにおいて、アンビル26の吸引孔28に対面する位置を除いた部分に基部23を接触させ、各吸引孔28によって基部23を吸引してアンビル26に密着固定させた状態で、基部23と反転部24とを超音波溶着することを特徴とする。 Sonouede, the upper surface of the anvil 26, previously formed a plurality of suction holes 28 distributed form in planar portion 26a for receiving at least the base portion 23, by placing the base portion 23 on the upper surface of the anvil 26, the base portion 23 In the portion 26 a for receiving the base 23, the base 23 is brought into contact with a portion of the anvil 26 excluding the position facing the suction hole 28, and the base 23 is sucked and fixed to the anvil 26 by the suction holes 28. And the reversing unit 24 are ultrasonically welded.

具体的には、アンビル26の吸引孔28の開口総面積を1.0〜5.0mm2 の範囲内に設定することが望まれる。吸引孔28の開口総面積が1.0mm2 よりも小さいと、基部23を十分には吸引できず、吸引孔28の開口総面積が5.0mm2 よりも大きくなると、吸引孔28に対面する位置以外の溶着部から押し出された溶融樹脂が、吸引孔28に対面する位置側へ流動し難くなって、反転部24と基部23との溶着強度が弱くなるからである。 Specifically, it is desirable to set the total opening area of the suction holes 28 of the anvil 26 within a range of 1.0 to 5.0 mm 2 . When the total opening area of the suction hole 28 is smaller than 1.0 mm 2 , the base 23 cannot be sufficiently sucked, and when the total opening area of the suction hole 28 is larger than 5.0 mm 2 , the suction hole 28 faces the suction hole 28. This is because the molten resin pushed out from the welded portion other than the position becomes difficult to flow toward the position facing the suction hole 28 and the welding strength between the reversing portion 24 and the base portion 23 is weakened.

本発明によれば、アンビル26の上面に載置したリーダーテープ10の基部23を、各吸引孔28で吸引してアンビル26に密着固定するので、量産に伴なってアンビル26の上面が磨耗したり、リーダーテープ10の厚み寸法にばらつきなどがあっても、基部23は、アンビル26にしっかりと固定されてアンビル26上で滑ることが確実に防止される。したがって、リーダーテープ10の反転部24と基部23とを確実に、かつ安定した溶着強度で超音波溶着できる。   According to the present invention, the base portion 23 of the leader tape 10 placed on the upper surface of the anvil 26 is sucked and fixed firmly to the anvil 26 by the suction holes 28, so that the upper surface of the anvil 26 is worn with mass production. Even if the thickness dimension of the leader tape 10 varies, the base portion 23 is firmly fixed to the anvil 26 and is reliably prevented from sliding on the anvil 26. Therefore, the inversion part 24 and the base part 23 of the leader tape 10 can be ultrasonically welded reliably and with stable welding strength.

(第1実施例) 図1ないし図5は、本発明に係る単リール型テープカートリッジの製造方法の第1実施例を示す。テープカートリッジは、図2および図3に示すごとく、上下ケース1a・1bを蓋合わせ状に接合してなる角箱状の本体ケース1を有し、その内部に配置した1個のリール2にデータを記録する磁気テープ3が巻かれている。本体ケース1の前面にはテープ引出口4が開口しており、このテープ引出口4は揺動開閉可能なドア5で開閉される。 First Embodiment FIGS. 1 to 5 show a first embodiment of a method for manufacturing a single reel type tape cartridge according to the present invention. As shown in FIGS. 2 and 3, the tape cartridge has a rectangular box-shaped main body case 1 formed by joining upper and lower cases 1a and 1b in a cover-like manner, and data is stored in one reel 2 arranged inside the case. Is wound around the magnetic tape 3. A tape outlet 4 is opened in front of the main body case 1, and the tape outlet 4 is opened and closed by a swingable door 5.

ドア5は、ばね部材で閉じ勝手に移動付勢されており、閉じ位置において、図外のロック機構でロック保持される。本体ケース1の対向する内隅の2個所には、リール2のフランジ周縁に設けたギヤ歯と係合して、不使用時にリール2を遊転不能に係合保持するリールロック6・7が設けられている。ケース背壁の一側には、誤消去防止用の切換えピース8を備えている。   The door 5 is closed and urged by a spring member, and is locked and held by a lock mechanism (not shown) in the closed position. Reel locks 6 and 7 that engage with gear teeth provided on the peripheral edge of the flange of the reel 2 and engage and hold the reel 2 in a non-rotatable state when not in use are provided at two opposite inner corners of the main body case 1. Is provided. A switching piece 8 for preventing erroneous erasure is provided on one side of the case back wall.

リール2に巻かれた磁気テープ3をテープドライブ側の捕捉体で自動的に捕捉するために、磁気テープ3の繰り出し端には、リーダーテープ10を介して先導ピース11が連結されている。先導ピース11は、ステンレス製の細い丸軸状のピン12と、ピン12の上下両端に設けた一対のプラスチック製掛止アーム13とでコ字枠状に形成されている。   In order to automatically capture the magnetic tape 3 wound around the reel 2 with a capturing device on the tape drive side, a leading piece 11 is connected to the feeding end of the magnetic tape 3 via a leader tape 10. The leading piece 11 is formed in a U-shaped frame shape with a thin round shaft pin 12 made of stainless steel and a pair of plastic latching arms 13 provided at both upper and lower ends of the pin 12.

図1においてピン12は、上下方向の中央に設けた大径のロック軸12aを挟んで、上下に小径の巻付軸12bをそれぞれ設けてあり、巻付軸12bの端に末広がり状のアンカー部12cをそれぞれ一体に形成されている。この巻付軸12bにリーダーテープ10の繰り出し端が巻き付けられる。各アンカー部12cは、掛止アーム13の基端側にそれぞれインサート固定されていて、掛止アーム13とピン12との分離を阻止している。   In FIG. 1, the pin 12 is provided with a small-diameter winding shaft 12b on both sides of a large-diameter lock shaft 12a provided at the center in the vertical direction, and an anchor portion having a divergent shape at the end of the winding shaft 12b. 12c is integrally formed. The feeding end of the leader tape 10 is wound around the winding shaft 12b. Each anchor portion 12 c is insert-fixed to the proximal end side of the latching arm 13 to prevent separation of the latching arm 13 and the pin 12.

各掛止アーム13は、ケース外面へ向かって突弧状に湾曲する左右横長のプラスチック成形品からなり、テープドライブ側の捕捉体が掛止連結される掛止溝16と、掛止アーム13の前面で下り傾斜する導入案内面17とを有する。テープドライブ側の捕捉体が、導入案内面17に沿って掛止溝16に案内されて掛止連結されることで、磁気テープ3が本体ケース1から引き出し操作される。   Each latch arm 13 is made of a horizontally long plastic molded product that curves in a projecting arc shape toward the outer surface of the case, and includes a latch groove 16 to which a trapping body on the tape drive side is latched and connected, and a front surface of the latch arm 13. And an introduction guide surface 17 inclined downward. The magnetic tape 3 is pulled out from the main body case 1 by the trapping body on the tape drive side being guided and connected to the retaining groove 16 along the introduction guide surface 17.

リーダーテープ10は、例えばポリエチレンテレフタレートやポリブチレンテレフタレートなどの弾性に富む比較的硬質のプラスチックシートで形成してあり、その繰り出し端側に設けた連結部20を前記ピン12の巻付軸12bに巻き付け連結して、先導ピース11と一体化する。   The leader tape 10 is formed of a relatively hard plastic sheet rich in elasticity, such as polyethylene terephthalate or polybutylene terephthalate, and the connecting portion 20 provided on the feed end side is wound around the winding shaft 12b of the pin 12. Connected and integrated with the leading piece 11.

その連結部20は、リーダーテープ10の端部において上下方向の中央部に切り欠き形成した横長の溝21と、溝21を挟んで上下に位置する一対の巻回片22とからなる。溝21の上下幅寸法は、ピン12のロック軸12aの上下長さ寸法より僅かに大きく設定してある。図5の展開図において、各巻回片22は、その基端側に設けられた一定幅寸法の基部(テープ面)23と、該基部23に連続して先すぼまりテーパー状に連出形成された反転部24とで形成してある。反転部24の先端上下は丸く面取り加工してある。   The connecting portion 20 includes a horizontally long groove 21 that is cut out at the center in the vertical direction at the end of the leader tape 10 and a pair of wound pieces 22 that are positioned vertically across the groove 21. The vertical width dimension of the groove 21 is set slightly larger than the vertical length dimension of the lock shaft 12 a of the pin 12. In the development view of FIG. 5, each winding piece 22 has a base portion (tape surface) 23 having a fixed width dimension provided on the base end side thereof, and is continuously formed in a tapered shape continuously with the base portion 23. And the inverted portion 24 formed. The upper and lower ends of the reversing unit 24 are rounded and chamfered.

リーダーテープ10と先導ピース11とは次のようにして連結する。図1および図4に示すごとく、リーダーテープ10の各巻回片22の反転部24をピン12の各巻付軸12bにそれぞれ巻き付けて反転させ、巻回片22と巻付軸12bとの間に僅かな遊動隙間を残して、超音波溶着装置のアンビル26の上面に巻回片22の基部23を載置して固定する。そして、超音波溶着装置の溶着ホーン27を巻回片22の反転部24の上側から押し付けて超音波振動させることで、反転部24と基部23とを溶着する。   The leader tape 10 and the leading piece 11 are connected as follows. As shown in FIGS. 1 and 4, the reversing portions 24 of the respective winding pieces 22 of the leader tape 10 are wound around the respective winding shafts 12 b of the pins 12 to be reversed, and a slight amount is provided between the winding pieces 22 and the winding shaft 12 b. The base 23 of the wound piece 22 is placed and fixed on the upper surface of the anvil 26 of the ultrasonic welding apparatus, leaving a free floating gap. And the inversion part 24 and the base part 23 are welded by pressing the welding horn 27 of an ultrasonic welding apparatus from the upper side of the inversion part 24 of the winding piece 22, and ultrasonically vibrating it.

アンビル26の上面において巻回片22の基部23を受け止める部分26aには、多数の丸孔状の吸引孔28が分散状に形成されている。各吸引孔28は、真空圧供給ライン29に接続されており、所定の真空圧で前記基部23を吸引する。   A large number of round hole-like suction holes 28 are formed in a distributed manner in a portion 26 a that receives the base 23 of the wound piece 22 on the upper surface of the anvil 26. Each suction hole 28 is connected to a vacuum pressure supply line 29 and sucks the base portion 23 with a predetermined vacuum pressure.

前記真空圧は、−60kPaとしたが、−80〜−30kPaの範囲内であればよい。吸引孔28の開口総面積は、4.0mm2 程度であるが、1.0〜5.0mm2 の範囲内であればよい。 The vacuum pressure is −60 kPa, but may be in the range of −80 to −30 kPa. Opening the total area of suction holes 28 is a 2 about 4.0 mm, it may be within the range of 1.0 to 5.0 mm 2.

具体的には、図外の冶具で先導ピース11を位置決め保持し、リーダーテープ10の各巻回片22の反転部24を反転させて基部23上に重ね、アンビル26上に該基部23を載置したのち、真空圧供給ライン29の電磁バルブ30を開いて、各吸引孔28によって吸引する。これにより、基部23が、各吸引孔28に吸い付けられ、アンビル26にしっかりと密着固定される。   Specifically, the leading piece 11 is positioned and held by a jig (not shown), the reversing portions 24 of the respective wound pieces 22 of the leader tape 10 are reversed and stacked on the base portion 23, and the base portion 23 is placed on the anvil 26. After that, the electromagnetic valve 30 of the vacuum pressure supply line 29 is opened, and suction is performed by each suction hole 28. As a result, the base 23 is sucked into each suction hole 28 and firmly fixed to the anvil 26.

この状態で、溶着ホーン27が下降して来て、巻回片22の反転部24を上側からアンビル26上に押し付ける(図4の状態)。次いで、溶着ホーン27が超音波振動すると、反転部24と基部23との接触面どうしが擦れ合って、その摩擦熱で反転部24と基部23とが溶着する。なお、符号Wは溶着部、符号31は真空ポンプを示す。   In this state, the welding horn 27 descends and presses the reversing portion 24 of the wound piece 22 onto the anvil 26 from above (state of FIG. 4). Next, when the welding horn 27 is ultrasonically vibrated, the contact surfaces of the reversing part 24 and the base part 23 rub against each other, and the reversing part 24 and the base part 23 are welded by the frictional heat. In addition, the code | symbol W shows a welding part and the code | symbol 31 shows a vacuum pump.

超音波溶着後には、溶着ホーン27が上昇するとともに電磁バルブ30が閉じられて、各吸引孔28での吸引が停止し、この後にリーダーテープ10の連結部20がピン12と共にアンビル26から取り外される。   After the ultrasonic welding, the welding horn 27 is raised and the electromagnetic valve 30 is closed to stop the suction in each suction hole 28. Thereafter, the connecting portion 20 of the leader tape 10 is removed from the anvil 26 together with the pin 12. .

上記のように巻回片22の基部23がアンビル26に吸着されていると、基部23がアンビル26上で滑って反転部24と連れ動くことがなく、反転部24と基部23とを確実に擦り合わせて超音波溶着できる。   As described above, when the base portion 23 of the wound piece 22 is adsorbed to the anvil 26, the base portion 23 does not slide on the anvil 26 and moves with the reversing portion 24, so that the reversing portion 24 and the base portion 23 are securely connected. Can be ultrasonically welded by rubbing.

リーダーテープ10の連結部20において、アンビル26の吸引孔28に対面する位置では、反転部24と基部23との密着性が低くなって充分な摩擦熱が得られないが、吸引孔28に対面する位置以外の溶着部から押し出された溶融樹脂が前記吸引孔28に対面する位置側へ流動するため、吸引孔28の存在位置においても反転部24と基部23とがしっかりと接合する。   In the connecting portion 20 of the leader tape 10, at the position facing the suction hole 28 of the anvil 26, the adhesiveness between the reversing portion 24 and the base portion 23 becomes low and sufficient frictional heat cannot be obtained. Since the molten resin pushed out from the welded part other than the position where it flows is moved to the position facing the suction hole 28, the reversing part 24 and the base part 23 are firmly joined even at the position where the suction hole 28 exists.

連結部20をピン12に連結した状態では、図1に示すように、上側の巻回片22の下縁、および下側の巻回片22の上縁が、それぞれピン12のロック軸12aと巻付軸12bとの間の段差で上下方向に位置決めされ、連結部20に対してピン12が上下方向に位置ずれするのを規制する。ピン12と巻回片22との間には、僅かな隙間が形成されており、先導ピース11とリーダーテープ10とは相対回転できる。   In a state where the connecting portion 20 is connected to the pin 12, as shown in FIG. 1, the lower edge of the upper winding piece 22 and the upper edge of the lower winding piece 22 are respectively connected to the lock shaft 12a of the pin 12. Positioning in the vertical direction is performed by a step between the winding shaft 12b and the positional displacement of the pin 12 in the vertical direction with respect to the connecting portion 20 is restricted. A slight gap is formed between the pin 12 and the wound piece 22 so that the leading piece 11 and the leader tape 10 can rotate relative to each other.

不使用時の先導ピース11を所定の待機姿勢で保持固定するため、図2に示すごとくテープ引出口4に臨む本体ケース1の内部には、ピン12のロック軸12aを係合捕捉するロック片33が配されており、その横隣に上下の掛止アーム13を受け止めるアーム受部34が上下ケース1a・1b側に設けられている。ロック片33は、ケース外面から挿入される解除ピンでロック解除操作される。   In order to hold and fix the leading piece 11 when not in use in a predetermined standby posture, a lock piece for engaging and capturing the lock shaft 12a of the pin 12 is provided inside the main body case 1 facing the tape outlet 4 as shown in FIG. 33 is arranged, and an arm receiving portion 34 for receiving the upper and lower hooking arms 13 is provided on the upper and lower cases 1a and 1b side to the side. The lock piece 33 is unlocked by a release pin inserted from the outer surface of the case.

(第2実施例) 図6は本発明方法の第2実施例を示しており、アンビル26の吸引孔28が角形孔状に形成されている。他は第1実施例と同じであるので、同じ部材に同じ符号を付してその説明を省略する。 (Second Embodiment) FIG. 6 shows a second embodiment of the method of the present invention, in which the suction hole 28 of the anvil 26 is formed in a square hole shape. Since others are the same as those of the first embodiment, the same members are denoted by the same reference numerals and the description thereof is omitted.

吸引孔28は、基部23をアンビル26に吸引固定できる形状であれば任意に設定でき、三角形状や楕円形状などであってもよい。   The suction hole 28 can be arbitrarily set as long as the base 23 can be sucked and fixed to the anvil 26, and may be triangular or elliptical.
