The present invention relates to a tape cutter to be formed.
 従来より、粘着テープ用のテープカッタは幅広い分野で使用されており、日常生活から業務用途に至るまで、テープカッタは必要不可欠な器具として定着している。現在では、テープカッタの機能を向上させ、また、使い勝手を良くするための技術が多く開発されている。例えば、本件の出願人は、特開2005-75560号や特開2006-103808号等に開示されているテープカッタの開発者であり、他にも機能性を高めたテープカッタの研究開発に従事している。 Conventionally, tape cutters for adhesive tapes have been used in a wide range of fields, and tape cutters have become established as indispensable instruments from daily life to business use. At present, many techniques for improving the function of the tape cutter and improving usability have been developed. For example, the applicant of this case is a developer of a tape cutter disclosed in Japanese Patent Application Laid-Open No. 2005-75560, Japanese Patent Application Laid-Open No. 2006-103808, etc., and is engaged in other research and development of a tape cutter with improved functionality. is doing.
 テープカッタの基本構成は、テープカッタ本体と、テープ保持部と、テープ切断部とからなり、テープ保持部に粘着テープが巻き取られたロール状のものが設置され、粘着テープが引き出されることによりテープ保持部が軸回転し、テープ切断部によって切断される。残留テープの先端は、テープ切断部に接着された状態で次の使用に供される状態となり、任意長のテープ切断片が必要に応じて順次供給されるものである。 The basic structure of a tape cutter consists of a tape cutter body, a tape holding part, and a tape cutting part. A roll-shaped tape with an adhesive tape wound around the tape holding part is installed, and the adhesive tape is pulled out. The tape holding part rotates and is cut by the tape cutting part. The leading end of the residual tape is in a state where it is used for the next use while being adhered to the tape cutting portion, and an arbitrary length of tape cutting pieces are sequentially supplied as necessary.
 テープカッタで供給されるカットされた粘着テープの使用態様として、包装などを接着し、剥がれないようにすることを目的とすることが多いと考えられる。例えば、業務用途として、スーパーや百貨店で商品を包装用紙で梱包したり、封筒や小包を梱包する場面で使用されるが、一方で、テープは貼り付ける当初から剥がすことを目的とすることもある。例えば、電気製品などの流通時に、部品が梱包内で遊動するのを防ぐため、各部品を一時的に粘着テープで留めることが広く一般的に行われている。 As a usage mode of the cut adhesive tape supplied with the tape cutter, it is considered that the purpose is often to adhere the packaging and the like so as not to peel off. For example, for business use, it is used for packing goods with packaging paper at supermarkets and department stores, and for packing envelopes and parcels. . For example, in order to prevent the parts from floating in the packaging during distribution of an electric product or the like, it is widely and generally performed to temporarily fasten each part with an adhesive tape.
 ところが、粘着テープの粘着の度合いによっては、粘着テープが対象物に強力に密着して剥がし難くなることがある。これを改善する一つの手段として、粘着テープの端部を粘着テープ側に折畳み、粘着面同士を貼り合わせて粘着性のない摘み部となるタブを先端に形成し、この部分を摘んで容易に剥がせるようにする工夫が、様々な分野で日常的に行われている。 However, depending on the degree of adhesion of the pressure-sensitive adhesive tape, the pressure-sensitive adhesive tape may be strongly adhered to the object and difficult to peel off. As one means of improving this, the end of the adhesive tape is folded to the adhesive tape side, the adhesive surfaces are bonded together to form a tab that becomes a non-adhesive knob, and this tab is easily picked. Ingenuity to make it peelable is routinely performed in various fields.
 このような粘着テープの端部に設ける摘み部となるタブの形成を半ば自動化したテープカッタに関する技術として、特開平11-49419号に開示された技術がある。この発明では、切断されたテープの先端にタブを形成するにあたり、テープカッタは、粘着テープの切断処理を行うカッター機構、残留テープの先端面に折込み処理を行う折込み機構および折込み部分の折曲げ処理を行う折曲げ機構を具備し、それぞれが各機構に設けられたカムにより、粘着テープの切断処理、残留テープの先端部の折込み処理、折込み部分の折曲げ処理の連係動作にズレを生じることがなく周期的な運動が与えられることで、次回の切断に備えて引き出し予定の粘着テープの先端にタブを形成する技術が開示されている。 There is a technique disclosed in Japanese Patent Application Laid-Open No. 11-49419 as a technique related to a tape cutter in which the formation of a tab serving as a knob provided at the end of such an adhesive tape is semi-automated. In the present invention, when forming a tab at the tip of the cut tape, the tape cutter includes a cutter mechanism for cutting the adhesive tape, a folding mechanism for folding the tip surface of the residual tape, and a folding process for the folded portion. Each of the mechanisms has a folding mechanism, and the cams provided in each mechanism may cause a shift in the linkage operation of the adhesive tape cutting process, the remaining tape tip folding process, and the folding part folding process. A technique for forming a tab at the tip of an adhesive tape to be pulled out in preparation for the next cutting is disclosed.
 開示された技術によると、正確に残留テープの先端にタブが形成されることになるものの、テープ折畳みのタイミングが微妙であるため、精度が少しでもずれるとタブの形成が出来なくなるという問題があった。また、機器の正確さが要求されることからテープカッタの製作コストが高く付くという問題もあった。 According to the disclosed technology, although the tab is accurately formed at the end of the residual tape, the tape folding timing is delicate, so that there is a problem that the tab cannot be formed if the accuracy is slightly shifted. It was. In addition, since the accuracy of the equipment is required, there is a problem that the production cost of the tape cutter is high.
 また、特開2004-284687では、接着テープを、可動カッター部を離隔回動して仮着受部に仮接着した状態で切断し、可動カッター部をバネによって復帰回動することにより、タブを形成する技術が開示されている。この技術によると、安価で耐久性の高いテープカッタを製造する事ができるが、確実に上方向にタブを形成することが難しいという問題点があった。また、粘着テープには強度や幅など用途に応じた様々な種類が存在するため、全ての種類の粘着テープに対応しているということが出来なかった。更に、カッタは常に外部に露出している構成であるため、使用時や保管時等に不慮の怪我を被る虞があった。 Further, in JP-A-2004-284687, the adhesive tape is cut in a state where the movable cutter portion is pivotally moved apart and temporarily adhered to the temporary attachment receiving portion, and the movable cutter portion is returned and rotated by a spring, whereby the tab is removed. A forming technique is disclosed. According to this technique, an inexpensive and highly durable tape cutter can be manufactured, but there is a problem that it is difficult to reliably form a tab in the upward direction. In addition, since there are various types of adhesive tapes depending on applications such as strength and width, it cannot be said that all types of adhesive tapes are supported. Furthermore, since the cutter is always exposed to the outside, there is a risk of accidental injury during use or storage.
 そこで、構造が複雑になり過ぎず、且つ正確に摘み部となるタブを形成することができ、安全性にも優れたテープカッタの開発が望まれていた。

In this embodiment, the tape holding part 20 uses a resin material. In order to prevent the posture of the tape cutter from becoming unstable due to the force with which the tape cutter body 10 pulls out the adhesive tape 25 when the adhesive tape 25 is pulled out, iron, lead, It is desirable to use heavy materials such as clay and concrete.
 粘着テープ25は、捲回された状態でテープ保持部20に回転自在に保持され、引き出し操作により粘着テープ25をテープ切断部50へと送出するテープ送出部30を通過して送出され、粘着テープの先端面(引き出された残テープの先頭)に粘着面同士を一定の長さで接着し摘み部となるタブを形成するタブ形成部40を介して、次回のテープ引き出し切断の際にタブの形成されたテープが切断されるようにテープ切断部50へと送出される。 The adhesive tape 25 is rotatably held by the tape holding unit 20 in a wound state, and is sent out through the tape sending unit 30 that sends the adhesive tape 25 to the tape cutting unit 50 by a pulling operation. Adhesive surfaces are bonded to the leading end surface of the tape (the leading end of the pulled-out remaining tape) with a certain length to form a tab serving as a knob, and the tab of the tab is cut during the next tape cutting. The formed tape is sent to the tape cutting unit 50 so as to be cut.
 テープ送出部30は、粘着テープ25をテープ保持部20からテープ切断部50へ送出するための構成である。テープ送出部30は、図2に示すように、揺動板32と、揺動ギア35が固着されたテープ送出ローラ34と、付勢ローラ36とから構成される。 The tape delivery unit 30 is configured to send the adhesive tape 25 from the tape holding unit 20 to the tape cutting unit 50.

Therefore, in this embodiment, as shown in FIG. 2, tension rollers 39a and 39b are provided in the vicinity of the tape feed roller 34 of the swing plate 32 and the tape cutter body 10 so that the adhesive tape 25 is in contact with the tape feed roller 34. It is configured to increase.
 タブ形成部40は、残留する粘着テープ25の先端に粘着面同士を一定の長さで接着した摘み部となるタブを次回の切断テープ用に形成するための構成であり、可動部42と、負荷抑制ローラ43と、タブ形成基部44と、タブ形成制御棒46とから構成される。 The tab forming part 40 is a structure for forming a tab to be a knob part in which the adhesive surfaces are bonded to the tip of the remaining adhesive tape 25 with a certain length for the next cutting tape, the movable part 42, The load suppression roller 43, the tab formation base 44, and the tab formation control rod 46 are configured.
 可動部42は、テープ送出部30から送出された粘着テープ25を粘着面を下にして水平に接触保持するための構成であり、テープカッタ本体10に前後動自在に装着される。粘着テープ25は、可動部42を介して、後述のタブ形成基部44乃至テープ切断部50に向けて送出されるため、可動部42で粘着テープ接触時に生じる摩擦による負荷を抑制することが望ましい。本実施例では、図2に示すように、可動部42のタブ形成部40側に負荷抑制ローラ43を備え、粘着テープ25との摩擦により生じる負荷を抑制している。 The movable part 42 is configured to hold the adhesive tape 25 delivered from the tape delivery part 30 in a horizontal contact with the adhesive surface down, and is mounted on the tape cutter body 10 so as to be movable back and forth. Since the adhesive tape 25 is sent toward a tab forming base 44 or a tape cutting unit 50 described later via the movable portion 42, it is desirable to suppress a load caused by friction generated when the movable portion 42 contacts the adhesive tape. In this embodiment, as shown in FIG. 2, a load suppression roller 43 is provided on the tab forming portion 40 side of the movable portion 42 to suppress a load caused by friction with the adhesive tape 25.
 タブ形成基部44は、残留する粘着テープ25の先端に摘み部となる両面を非粘着面とするタブを形成する構成であり、テープカッタの待機状態では可動部42と接する位置に保持されている。粘着テープ25の引き出し時には、テープ切断部50と共にテープの引き出される方向に軸回転し、テープ切断部50によるテープの切断が完了した時に、引き出されて残った残テープ、すなわち切出し基の粘着テープ25のその先端を保持して元の位置まで逆戻り回転するという一連の動作を行う。この逆戻り回転の際、可動部42上に位置する、引き出されて残った残テープは、逆戻りせずそのままの位置で保持されるため、タブ形成基部44に保持された切出し基の粘着テープ25の先端が可動部42上に位置する粘着テープに接近し、粘着面同士が接合し接着することにより、引き出された残テープの先頭端に粘着面が内側に折り合わされて外側が非粘着面となるタブが形成される。 The tab forming base 44 is configured to form a tab having a non-adhesive surface on both sides that become the knobs at the tip of the remaining adhesive tape 25, and is held at a position in contact with the movable portion 42 in the standby state of the tape cutter. . When the adhesive tape 25 is pulled out, the tape is rotated in the direction in which the tape is pulled out together with the tape cutting unit 50, and when the tape cutting by the tape cutting unit 50 is completed, the remaining tape that has been pulled out, that is, the adhesive tape 25 of the cutting base. A series of operations are performed in such a manner that the tip of the lens is held and rotated back to the original position. During this reversal rotation, the remaining tape that has been pulled out and remains on the movable portion 42 is not reverted and is held in that position, so that the cut-out adhesive tape 25 held by the tab forming base 44 When the front end approaches the adhesive tape located on the movable portion 42 and the adhesive surfaces are bonded and bonded together, the adhesive surface is folded inward at the leading end of the drawn-out remaining tape, and the outer side becomes a non-adhesive surface. A tab is formed.
 タブ形成制御棒46は、タブ形成基部44の回転軸近傍に装着され、後述のタブ形成部制御カム64に当接し、カムの回転移動によって伝達される力を受けて、タブ形成基部44を前後動させる。 The tab formation control rod 46 is mounted in the vicinity of the rotation axis of the tab formation base 44, abuts on a tab formation portion control cam 64, which will be described later, receives the force transmitted by the rotational movement of the cam, and moves the tab formation base 44 back and forth. Move.
 タブ形成部40は、更にタブ形成制御機構60を装備している。タブ形成制御機構60は、タブ形成部40によるタブ形成のための前後の回転動作を制御するための装置であり、図3に示すように、カム制御ギア62と、タブ形成部制御カム64とからなる。 The tab forming unit 40 is further equipped with a tab forming control mechanism 60. The tab formation control mechanism 60 is a device for controlling the front and rear rotational operations for tab formation by the tab formation portion 40, and as shown in FIG. 3, a cam control gear 62, a tab formation portion control cam 64, Consists of.
 カム制御ギア62は、テープ引き出し動作時に揺動ギア35からの回転力を受け、粘着テープ25の引き出しに応じて回転するギア体である。粘着テープ25の切断後は、揺動ギア35からの回転力の伝達が解除され、カム制御ギア62は逆回転可能となり、待機状態に戻る。 The cam control gear 62 is a gear body that receives the rotational force from the rocking gear 35 during the tape drawing operation and rotates in accordance with the drawing of the adhesive tape 25. After the adhesive tape 25 is cut, the transmission of the rotational force from the swing gear 35 is released, and the cam control gear 62 can be rotated in the reverse direction and returns to the standby state.
 また、タブ形成部制御カム64は、タブ形成制御棒46と当接し、タブ形成部制御カム64の回転動作時にカムの形状に応じてタブ形成基部44を揺動させるためのカム状部材であり、カム制御ギア62に固着され、カム制御ギア62と共に回転する。 The tab forming portion control cam 64 is a cam-like member that abuts on the tab forming control rod 46 and swings the tab forming base 44 according to the shape of the cam when the tab forming portion control cam 64 rotates. The cam control gear 62 is fixed and rotates together with the cam control gear 62.
 テープ引き出し動作時には、揺動ギア35からの回転力の伝達によりカム制御ギア62が回転し、同時にタブ形成部制御カム64が回転することで、タブ形成制御棒46に力が伝達されてタブ形成基部44がテープ送出方向に移動する。テープ切断完了後は揺動ギア35からの回転力の伝達が解除されるため、カム制御ギア62は逆回転し、タブ形成部制御カム64も逆回転して元の位置に戻る事により、タブ形成制御棒46への力の伝達も解除され、タブ形成基部44も後退して元の位置に戻る。 When the tape is pulled out, the cam control gear 62 is rotated by the transmission of the rotational force from the rocking gear 35, and at the same time, the tab forming portion control cam 64 is rotated, whereby the force is transmitted to the tab forming control rod 46 to form the tab. The base 44 moves in the tape feeding direction. Since the transmission of the rotational force from the swing gear 35 is released after the tape cutting is completed, the cam control gear 62 rotates in the reverse direction, and the tab forming portion control cam 64 also rotates in the reverse direction to return to the original position. The transmission of force to the formation control rod 46 is also released, and the tab formation base 44 is also retracted and returned to its original position.
 次に、本発明に係るテープカッタの動作を、図によって順次説明する。本発明のテープカッタは、テープ引き出し前の待機状態では、図4に示すように、揺動板32は、テープカッタ本体10と揺動板32に固着される揺動制御弾性体38の復元力によって固定されている。本実施例では、揺動ギア35の回転力をカム制御ギア62に伝達するため、テープカッタ本体10に回転自在に固定される固定ギア66を設けており、揺動ギア35は固定ギア66と離れた状態で保持される。なお、この状態では、タブ形成基部44およびテープ切断部50は、可動部42と接する位置に保持されている。 Next, the operation of the tape cutter according to the present invention will be described sequentially with reference to the drawings. In the tape cutter of the present invention, in the standby state before the tape is pulled out, as shown in FIG. 4, the swing plate 32 is a restoring force of the swing control elastic body 38 fixed to the tape cutter body 10 and the swing plate 32. It is fixed by. In this embodiment, in order to transmit the rotational force of the oscillating gear 35 to the cam control gear 62, a fixed gear 66 that is rotatably fixed to the tape cutter body 10 is provided. It is held away. In this state, the tab forming base portion 44 and the tape cutting portion 50 are held at a position in contact with the movable portion 42.
 テープ引き出し時には、テープ送出部30の付勢ローラ36が粘着テープ25の引き出し力によって揺動板32を揺動させる。この動作に伴い、図5に示すようにテープ送出ローラ34に固着された前記揺動ギア35が移動して固定ギア66と噛合し、テープ送出ローラ34の回転力が伝達可能となる。更に粘着テープ25を引き出すと、テープ送出ローラ34が回転する事で揺動ギア35および固定ギア66が連動して回転し、カム制御ギア62に回転力が伝達される。タブ形成部制御カム64は制御ギア62の回転に伴い回転するため、タブ形成制御棒46が回転するタブ形成部制御カム64の形状に応じて移動するのに伴い、図5に示すようにタブ形成基部44およびテープ切断部50がテープ送出方向に移動する。これにより、粘着テープ25の切断が可能となる。 When pulling out the tape, the urging roller 36 of the tape delivery unit 30 swings the swinging plate 32 by the pulling force of the adhesive tape 25. With this operation, as shown in FIG. 5, the swing gear 35 fixed to the tape feed roller 34 moves and meshes with the fixed gear 66, so that the rotational force of the tape feed roller 34 can be transmitted. When the adhesive tape 25 is further pulled out, the tape feed roller 34 rotates, whereby the swing gear 35 and the fixed gear 66 rotate in conjunction with each other, and the rotational force is transmitted to the cam control gear 62. Since the tab forming portion control cam 64 rotates with the rotation of the control gear 62, the tab forming control rod 46 moves in accordance with the shape of the rotating tab forming portion control cam 64 as shown in FIG. The forming base 44 and the tape cutting unit 50 move in the tape feeding direction. Thereby, the adhesive tape 25 can be cut.
 なお、本実施例では、図5に示すように、固定ギア66とカム制御ギア62の間に2つのギアを設けた構成としているが、この実施例に限定されるものではなく、固定ギア66とカム制御ギア62を直接接続する構成としても良い。また、単一または複数のギアを介して前記カム制御ギア62に回転力を伝達する構成とすることが考えられる。 In this embodiment, as shown in FIG. 5, the two gears are provided between the fixed gear 66 and the cam control gear 62. However, the present invention is not limited to this embodiment, and the fixed gear 66 is not limited thereto. The cam control gear 62 may be directly connected. Further, it is conceivable that a rotational force is transmitted to the cam control gear 62 via a single gear or a plurality of gears.
 テープ切断完了時には、タブ形成基部44が引き出された残テープの先端を貼付保持した状態となる。なお、テープ切断部50は、タブ形成基部44に併設され、カッタ52を有し前記タブ形成基部44の前後動に応動する構成であるため、図5に示すように、テープ切断部50が引き出されて残った残テープを貼付保持する構成とすることが望ましく、より確実にタブの形成が可能となる。 When the tape cutting is completed, the end of the remaining tape from which the tab forming base 44 has been pulled out is stuck and held. Since the tape cutting part 50 is provided alongside the tab forming base 44 and has a cutter 52 and responds to the back and forth movement of the tab forming base 44, the tape cutting part 50 is pulled out as shown in FIG. It is desirable to have a configuration in which the remaining tape that remains is pasted and held, and the tab can be formed more reliably.
 テープ切断完了後、揺動ギア35が揺動制御弾性体38の復元力により逆方向へ移動して固定ギア66との噛合が解除される。これにより、カム制御ギア62への回転力が解除され、カム制御ギア62は逆方向へ回転可能となる。 After completion of the tape cutting, the rocking gear 35 is moved in the reverse direction by the restoring force of the rocking control elastic body 38 and the meshing with the fixed gear 66 is released. Thereby, the rotational force to the cam control gear 62 is released, and the cam control gear 62 can rotate in the reverse direction.
 カム制御ギア62は内部にタブ形成弾性体(図示せず)を設けている。このタブ形成弾性体の復元力によりカム制御ギア62およびタブ形成部制御カム64が逆回転し、これに伴いタブ形成基部44およびテープ切断部50も逆回転する。なお、本実施例では、タブ形成弾性体は弦巻バネを使用しているが、これに限定されるものではない。 The cam control gear 62 is provided with a tab forming elastic body (not shown). Due to the restoring force of the tab forming elastic body, the cam control gear 62 and the tab forming portion control cam 64 are reversely rotated, and accordingly, the tab forming base portion 44 and the tape cutting portion 50 are also reversely rotated. In this embodiment, the tab-forming elastic body uses a string spring, but is not limited to this.
 この逆回転の際、図6に示すように、可動部42上に位置する引き出されて残った残テープは、逆戻りせずそのままの位置で保持されるため、テープ保持部58に保持された切出し基の粘着テープの先端が可動部42上のテープ係止部48に位置する粘着テープ25に接近し、引き出された残テープの先頭端にタブが形成される。 At the time of this reverse rotation, as shown in FIG. 6, the remaining tape that has been pulled out and remains on the movable portion 42 is not reversed and is held in that position, so that the cut held by the tape holding portion 58 is retained. The leading end of the base adhesive tape approaches the adhesive tape 25 located at the tape locking portion 48 on the movable portion 42, and a tab is formed at the leading end of the drawn-out remaining tape.
 テープ切断部50は、引き出された粘着テープ25を切断する構成であり、図7に示すように、カッタ52と、カッタを固定するカッタホルダ54と、上下動自在に装着されるカッタカバー56とから構成される。 The tape cutting unit 50 is configured to cut the drawn adhesive tape 25. As shown in FIG. 7, the tape cutting unit 50 includes a cutter 52, a cutter holder 54 that fixes the cutter, and a cutter cover 56 that is mounted so as to be movable up and down. Composed.
 テープ切断部50は、テープ引き出し時に、タブ形成基部44から分離移動し、テープ切断完了後にタブ形成基部44に合体係合する構成とすることが可能である。この構成とすることにより、テープ切断部50が引き出された残テープを貼付保持する構成とした場合に、テープ引き出し時に可動部42とテープ切断部50の間隔を充分確保し、且つ、残テープを貼付しやすい構造とすることが可能となる。 The tape cutting unit 50 can be separated and moved from the tab forming base 44 when the tape is pulled out, and can be engaged with the tab forming base 44 after the tape cutting is completed. With this configuration, when the tape cutting unit 50 is configured to affix and hold the pulled-out residual tape, a sufficient interval between the movable unit 42 and the tape cutting unit 50 is secured when the tape is pulled out, and the remaining tape is It becomes possible to make the structure easy to stick.
 また、テープ切断部50は、図4および図5に示すように、テープ引き出し時に、カッタカバー56を下降移動してカッタ52を露出させることで切断可能とし、テープ切断後には、カッタカバー56を上昇移動してカッタ52を格納保持する構成となっている。これにより、テープ引き出し前の待機状態ではカッタ52が露出していないため、指等がカッタ52に直接接触する事による怪我を防止することができ、安全なテープカッタを提供する事が可能となる。 As shown in FIGS. 4 and 5, the tape cutting unit 50 can be cut by moving the cutter cover 56 downward to expose the cutter 52 when the tape is pulled out. The cutter 52 is stored and held by moving upward. Thereby, since the cutter 52 is not exposed in the standby state before the tape is pulled out, it is possible to prevent an injury caused by a finger or the like directly contacting the cutter 52 and to provide a safe tape cutter. .
 タブ形成部40の可動部42は、テープ引き出し動作に応じて前後移動自在にテープカッタ本体10に装着される構成である。揺動板32とカム制御ギア62は、テープ切断完了時にそれぞれ揺動制御弾性体38の復元力およびタブ形成弾性体(図示せず)の復元力によって、逆回転する構成となっている。しかし、粘着テープ25の張力が強いと、揺動板32が逆回転できず、揺動ギア35と固定ギア66の噛合が解除されないという状態が生じ得る。 The movable part 42 of the tab forming part 40 is configured to be attached to the tape cutter main body 10 so as to be movable back and forth in accordance with the tape drawing operation. The oscillating plate 32 and the cam control gear 62 are configured to rotate in reverse by the restoring force of the oscillating control elastic body 38 and the restoring force of the tab forming elastic body (not shown), respectively, when the tape cutting is completed. However, if the tension of the adhesive tape 25 is strong, the swing plate 32 cannot be rotated in the reverse direction, and the meshing between the swing gear 35 and the fixed gear 66 cannot be released.
 これを回避するため、テープ引き出し時には可動部42がテープ送出方向へ移動をし、テープ切断完了時には可動部42が後退移動する構成としている。これにより、テープ切断完了時に粘着テープ25の張力が開放されるため、揺動板32が容易に逆回転し、揺動ギア35と固定ギア66の噛合が解除される。これによってカム制御ギア62は逆回転可能となり、待機状態に戻る。タブ形成基部44およびテープ切断部50も確実に元の位置に戻るため、安定した粘着テープへのタブの形成が可能となった。 In order to avoid this, the movable part 42 moves in the tape feeding direction when the tape is pulled out, and the movable part 42 moves backward when the tape cutting is completed. Thereby, since the tension of the adhesive tape 25 is released when the tape cutting is completed, the swing plate 32 easily reversely rotates, and the meshing between the swing gear 35 and the fixed gear 66 is released. As a result, the cam control gear 62 can rotate in the reverse direction and returns to the standby state. Since the tab forming base 44 and the tape cutting part 50 also surely return to their original positions, it is possible to form a tab on a stable adhesive tape.
 テープ切断部50は、図2および図7に示すように、切断時に引き出された残テープを保持するテープ保持部58を具備する構成とすることが可能である。すなわち、テープ保持部58に、切断時に引き出された残テープが貼付した状態で、テープ切断部50は逆回転して元の位置に戻ることになる。 As shown in FIGS. 2 and 7, the tape cutting unit 50 can be configured to include a tape holding unit 58 that holds the remaining tape drawn at the time of cutting. In other words, the tape cutting unit 50 rotates in the reverse direction and returns to the original position with the tape remaining at the time of cutting attached to the tape holding unit 58.
 また、可動部42は、図2に示すように、引き出された残テープの剥がれを防止する長板部材からなるテープ係止部48をテープ引き出し方向と直向する横向きに具備する構成とすることが可能である。正確に引き出された残テープにタブを形成するには、可動部42上に位置する引き出された残テープが逆戻りせずそのままの位置で保持されている必要があるが、長板からなる盛り上がり部となるテープ係止部48を具備することで、引き出された残テープが可動部42上で接着した状態でより確実に保持されることになる。 Further, as shown in FIG. 2, the movable portion 42 is configured to include a tape locking portion 48 made of a long plate member that prevents the pulled-out remaining tape from peeling off in a lateral direction that is perpendicular to the tape drawing direction. Is possible. In order to form a tab on the correctly drawn remaining tape, the drawn remaining tape located on the movable portion 42 needs to be held in a position without being reversed. By providing the tape locking portion 48 to be, the pulled-out residual tape is more reliably held in a state where it is adhered on the movable portion 42.
 これにより、引き出された残テープのテープ係止部48からの剥がれを防止でき、安定したタブの形成が可能となる。なお、テープ保持部58およびテープ係止部48は、粘着テープに確実に貼り付いて保持する必要があるため、本実施例では、それぞれの素材としてウレタン等を使用しているが、これに限定されるものではなく、適宜材質を選択する事が可能である。 Thereby, it is possible to prevent the pulled-out residual tape from being peeled off from the tape locking portion 48, and it is possible to form a stable tab. Since the tape holding portion 58 and the tape locking portion 48 need to be securely attached and held on the adhesive tape, in this embodiment, urethane or the like is used as each material. However, the present invention is not limited to this. However, it is possible to select a material as appropriate.
 テープ係止部48は、図8に示すように、頂面を山形に形成した横長の断面略半円筒形または蒲鉾形とすることが可能である。この形状とすることにより、粘着テープ25の粘着面がテープ係止部48に接着する面積を拡大する事が出来るとともに、粘着テープ25の張力に対する摩擦力を増加する事が可能となる。これにより、引き出された残テープがテープ係止部48から剥がれることを防止することが可能となり、かつ、可動部42上に位置する引き出された残テープが逆戻りせずそのままの位置でより確実に保持することが可能となる。 As shown in FIG. 8, the tape locking portion 48 can have a horizontally long cross-sectional substantially semi-cylindrical shape or a bowl shape with the top surface formed in a mountain shape. By adopting this shape, the area where the adhesive surface of the adhesive tape 25 adheres to the tape locking portion 48 can be increased, and the frictional force against the tension of the adhesive tape 25 can be increased. As a result, it is possible to prevent the pulled-out residual tape from being peeled off from the tape locking portion 48, and the pulled-out residual tape positioned on the movable portion 42 does not return and more reliably in its position. It becomes possible to hold.
 また、テープ係止部48は、更に図9に示すように、断面略半円筒形の長板を2分割した形状であって、その中央に粘着テープの断面を略U字型に成形するためのテープ係止間隙41を設けた構成である。テープ切断時に、粘着テープ25がテープ係止間隙41上に送られ、2分割した形状のテープ係止部48に接着すると、粘着テープ25の横幅方向が断面略U字型に湾曲する。この状態で、引き出された残テープに、タブ形成部40によってタブが形成されると、テープが上方に折れ曲がりやすくなる。すなわち、粘着テープ25にこの変形を加えることにより、タブが残テープ上方に向けて形成されやすくなるため、タブを確実に形成することが可能となる。 Further, as shown in FIG. 9, the tape locking portion 48 has a shape in which a long plate having a substantially semi-cylindrical cross section is divided into two, and the cross section of the adhesive tape is formed into a substantially U-shape at the center thereof. The tape locking gap 41 is provided. When the tape is cut, when the adhesive tape 25 is fed onto the tape locking gap 41 and bonded to the tape locking portion 48 having a two-divided shape, the lateral width direction of the adhesive tape 25 is curved into a substantially U-shaped cross section. In this state, when a tab is formed by the tab forming portion 40 on the pulled-out remaining tape, the tape is easily bent upward. That is, by applying this deformation to the adhesive tape 25, the tabs are easily formed toward the upper side of the remaining tape, so that the tabs can be reliably formed.
 タブ形成部40の可動部42は、図10に示すように、テープ係止ユニット45を着脱自在に装着した構成としている。テープ係止ユニット45は、テープ係止部48を保持する土台となるテープ係止基部47と、引き出された残テープを接着保持するテープ係止部48からなり、テープ係止部48が粘着テープ25の進行方向と直交する向きとなるように可動部42に着脱自在に装着される。この構成とすることにより、使用する粘着テープ25の幅、粘着度、硬さなどの種類に応じて、テープ係止部48の形状を適宜選択して交換することが可能となるとともに、テープ係止部48が劣化した際には容易に交換することが可能となり、より使い勝手の良いテープカッタを構成することが可能となる。 The movable part 42 of the tab forming part 40 has a structure in which a tape locking unit 45 is detachably mounted as shown in FIG. The tape locking unit 45 includes a tape locking base 47 serving as a base for holding the tape locking portion 48 and a tape locking portion 48 for adhering and holding the pulled-out residual tape. The tape locking portion 48 is an adhesive tape. The movable portion 42 is detachably mounted so as to be in a direction orthogonal to the direction of travel of 25. With this configuration, the shape of the tape locking portion 48 can be appropriately selected and replaced according to the type of the adhesive tape 25 to be used, such as the width, the degree of adhesion, and the hardness. When the stop 48 is deteriorated, it can be easily replaced, and a more convenient tape cutter can be configured.
 なお、テープ係止ユニット45は、本実施例では螺子により固定する構成となっているが、これに限定されるものではなく、嵌め込み式、スライド挿入式など、設置方法を適宜選択することが可能である。 The tape locking unit 45 is configured to be fixed by a screw in this embodiment, but is not limited thereto, and an installation method such as a fitting type or a slide insertion type can be appropriately selected. It is.
 タブ形成基部44は、非粘着上面49を装備している。非粘着上面49は非粘着性素材からなり、粘着テープ25が接着しない材質からなる構成である。非粘着上面49は、図5に示すように、テープ保持部58およびテープ係止部48の間に、テープ引き出し時に粘着テープ25の粘着面に接してテープを上方向に付勢するように装着される。これにより、引き出された残テープにタブを形成する際に、タブが逆側(下方向)に折れ曲がる事を防ぎ、確実に粘着面同士を接合させることが可能となった。 The tab forming base 44 is equipped with a non-adhesive top surface 49. The non-adhesive upper surface 49 is made of a non-adhesive material and is made of a material to which the adhesive tape 25 does not adhere. As shown in FIG. 5, the non-adhesive upper surface 49 is mounted between the tape holding portion 58 and the tape locking portion 48 so as to contact the adhesive surface of the adhesive tape 25 and urge the tape upward when the tape is pulled out. Is done. Thereby, when forming a tab in the pulled-out residual tape, it became possible to prevent a tab from bending to the reverse side (downward), and to join adhesive surfaces reliably.
 テープ送出ローラ34、テンションローラ39a、39b、付勢ローラ36、負荷抑制ローラ43は、ローラ端部から中心部に向けて直径を太くして、円筒の長手方向中央部が膨らんだ樽状としたものを使用することが可能である。テープカッタ本体10内での粘着テープ25の直進性が損なわれると、確実なタブの形成が困難となる。樽状とすることにより、粘着テープ送出時の粘着テープ25の直進性を確保することが可能となり、安定したタブの形成が可能となった。なお、各ローラの形状は樽状に限定されるものではなく、粘着テープの直進性が得られる形状を適宜選択する事が可能である。 The tape feed roller 34, the tension rollers 39a and 39b, the urging roller 36, and the load suppression roller 43 have a barrel shape in which the diameter increases from the roller end toward the center and the center in the longitudinal direction of the cylinder swells. Can be used. If the straightness of the adhesive tape 25 in the tape cutter body 10 is impaired, it is difficult to form a reliable tab. By using the barrel shape, it is possible to ensure the straightness of the adhesive tape 25 when the adhesive tape is delivered, and a stable tab can be formed. In addition, the shape of each roller is not limited to a barrel shape, and it is possible to appropriately select a shape that allows straightness of the adhesive tape to be obtained.
 また、テープ保持部20は、トルク調整機構24を装備することが可能である。トルク調整機構24は、粘着テープ25を保持するリール22の回転トルクを調整する構成であり、本実施例では、螺子の締め付けによる回転トルクの制御を行う構成としている。これにより、幅、厚み、大きさ、粘着度が異なる粘着テープであっても、安定して本装置に導入してタブを形成する事が可能となり、あらゆる種類の粘着テープを使用することが可能となった。 Further, the tape holding unit 20 can be equipped with a torque adjusting mechanism 24. The torque adjusting mechanism 24 is configured to adjust the rotational torque of the reel 22 that holds the adhesive tape 25. In this embodiment, the torque adjusting mechanism 24 is configured to control the rotational torque by tightening the screws. As a result, even adhesive tapes with different widths, thicknesses, sizes, and adhesion levels can be stably introduced into the device to form tabs, and all types of adhesive tapes can be used. It became.
