Description

技術分野
本発明は自動車の車体等に付着した粘着物を効率よく剥離除去する粘着物剥離除去装置に関する。
背景技術
従来自動車の車体には、粘着剤等の粘着物によりステッカや各種内外装材が接着されている。
これらステッカや内外装材は、車体を修理したり、再塗装する場合邪魔になるため、車体より剥離したり取り外しているが、これらステッカや、内外装材を取り外した後の粘着物を手作業で除去するには、多くの時間と労力を必要とするため作業率が大変悪い等の問題がある。
かかる問題を改善するため、例えば実公平８−９１４３号公報で、車体等に接着されたステッカ等を剥離除去する粘着剤剥離用回転ロールが提案されている。
前記公報の粘着剤剥離用回転ロールは、表面に弾性力と耐摩耗性を有するロール状の本体を、電気グラインダやエアグラインダにより回転させて剥離対象面に圧着することにより、剥離対象面側の粘着剤を摩擦熱で軟化させて剥離除去するように構成されている。
しかし前記公報の粘着剤剥離用回転ロールは、ロール状の本体がゴムまたは合成樹脂により形成されたソリッド構造のため、剥離対象面に本体を圧接させると、本体と剥離対象面との摩擦により本体が摩耗して多量の摩耗粉が発生する。
この摩耗粉は微粉末のため、ロール状の本体が回転するのに伴い周囲へ飛散して作業環境を悪化させることから、作業能率を低下させる原因となると共に、飛散した摩耗粉が作業者の目や鼻、口から体内に侵入するため、作業者の健康を損ねる等の問題がある。
本発明はかかる従来の問題点を改善するためになされたもので、微粉末の摩耗粉が周囲に飛散することがない粘着物の剥離除去装置を提供することを目的とするものである。
発明の開示
本発明は、車体等に付着した粘着物を剥離除去する粘着物剥離除去装置を、回転駆動手段に取り付ける取り付け軸と、取り付け軸に設けられたテープ取り付け部材と、テープ取り付け部材に着脱自在に取り付けられた粘着テープよりなる剥離部材と、テープ取り付け部材を軸方向に加圧することにより、剥離部材をテープ取り付け部材に固定する加圧手段とから構成したことから、電動ドリルやエアドリルのような回転駆動手段により取り付け軸を回転させて、剥離部材の外周面を剥離すべきステッカや、車体に固着した粘着物に押し当てることにより、ステッカや粘着物と剥離部材の間に摩擦熱が発生してステッカの接着剤や粘着物を軟化させ、同時に摩擦力により粘着テープの粘着面が接着剤や粘着物と結合して車体より剥離することができるため、車体に粘着したステッカや、車体に固着した粘着物を能率よく剥離することができる。
また剥離されたステッカや粘着物は、テープの削りカスと共に固まりとなって脱落するため、従来のゴムや樹脂により形成されたローラにより剥離する場合と異なり、微細な摩耗粉が周囲に飛散することがなく、これによって作業環境が悪化することにより作業能率を低下させたり、飛散した摩耗粉が作業者の目や鼻、口から体内に侵入して作業者の健康を損ねる等の従来の問題を解消することができる。
さらに本発明は、加圧手段をテープ取り付け部材の両端面に当接させた押圧板と、取り付け軸に形成されたねじ部に螺装され、かつ押圧板をテープ取り付け部材の軸方向へ加圧するナットとより構成したことから、ナットを締付けるだけでテープ取り付け部材に剥離部材を確実に固定することができるため、作業中剥離部材が空転して剥離作業ができなくなったり、作業能率が低下する等の虞がないと共に、摩耗した剥離部材を新しい剥離部材に交換する作業も短時間で容易に行えるようになる。
また押圧板のテープ取り付け部材の端面と当接する面に、複数の突起を突設したことから、加圧手段を締め付けた際、押圧板より突設した突起がテープ取り付け部材の端面に食い込むため、押圧板とテープ取り付け部材の間に滑りが生じることがないと共に、テープ取り付け部材の両端側の角部に面取り面を形成した上、外周面に複数本の凹溝を軸線方向に形成したことから、加圧手段によりテープ取り付け部材３加圧した際、テープ取り付け部材が径方向へ膨張しやすくなるため、テープ取り付け部材の外周面と剥離部材の芯材内周面との接触面圧が上がって、テープ取り付け部材より剥離部材が外れにくくなることから、作業時の安全性が向上する。
さらに本発明は、テープ取り付け部材を、テーパ状に形成された２部材より形成し、かつ小径部側が互いに対向するよう取り付け軸に取り付けると共に、テープ取り付け部材のテーパ面で剥離部材の芯体を保持するようにしたことから、芯材の内径が変ってもテープ取り付け部材に剥離部材を取り付けることができるため、内径の異なる種々の剥離部材に対応することができる。
また剥離部材に、耐熱性を有するマスキングテープや、布テープ等を使用したことから、消耗品である剥離部材が安価に得られるようになる。
発明を実施するための最良の形態
本発明の実施の形態を、図面を参照して詳述する。
第１図及び第２図に示す粘着物剥離装置の本体１は、取り付け軸２と、この取り付け軸２の一端側に設けられた弾性体よりなる円筒状のテープ取り付け部材３及びテープ取り付け部材３を加圧する手段４よりなる。取り付け軸２の一端側にはねじ部２ａが形成されていて、このねじ部２ａにゴムや合成樹脂により円筒状に形成されたテープ取り付け部材３の中心部が嵌捜されており、テープ取り付け部材３の両端面には、テープ取り付け部材３の外径とほぼ同径の座金により形成された一対の押圧板４ａが当接されている。
加圧手段４ａは前記押圧板４ａと、取り付け軸２のねじ部２ａに螺合された一対のナット４ｂより構成されていて、これらナット４ｂを締め付けて、一対の押圧手段４ａｂによりテープ取り付け部材３の端面を取り付け軸２の軸方向より加圧することにより、テープ取り付け部材３の外周面を半径方向へ膨張できるようになっている。
なお作業中ナット４ｂが緩まないようダブルナットにしたり、取り付け軸２のねじ部２ａを回転駆動手段の回転方向に対して逆ねじにして、取り付け軸２の回転に伴いナット４ｂが締め付けられるようにしてもよい。
一方車体等に接着されたステッカや、内外装材を車体より取り外した後に車体に残留する粘着物を剥離する剥離部材５は、筒状の芯体５ａとこの芯体５ａの外周にロール状に巻かれた粘着テープ５ｂよりなる。
芯体５ａは内径が前記テープ取り付け部材３の外径よりやや大きく形成されていて、芯体５ａ内にテープ取り付け部材３を容易に挿入できるようになっていると共に、加圧手段４によりテープ取り付け部材３を軸方向より加圧して、取り付け部材３の外周面を半径方向へ膨張させた場合、芯体５ａの内面がテープ取り付け部材３の外周面に密着して、両者の摩擦力によりテープ取り付け部材３に対して剥離部材５が空転しないようになっている。
また粘着テープ５ｂには、車体に焼き付け塗装をする場合に使用するマスキングテープか、同等品が使用されている。
マスキングテープは、焼き付け塗装する際の高温にも耐えられるように、和紙により形成されたテープ素材の少なくとも片面に耐熱性を有するアクリル系接着剤を塗布して粘着テープ５ｂを形成したもので、１００°Ｃ以上の高温にも耐えられるようになっている。
また既製のマスキングテープは、幅が例えば６ｍｍ、１５ｍｍ、２４ｍｍ、３０ｍｍのように規格化されており、これら規格に合わせて、剥離部材５を取り付ける取り付け部材３の長さも、ほぼ６ｍｍ、１５ｍｍ、２４ｍｍ、３０ｍｍのものが予め用意されている。
次に前記構成された粘着物剥離装置の作用を説明する。
車体に貼着されたステッカやシールは、容易に剥離できないように合成樹脂系の接着剤により強固に車体に接着されており、車体の内側に取り付けられた内装材、車体の外側に取り付けられたモールやサイドバイザ等の外装材は、合成樹脂系の接着剤により強固に車体に接着されている。
このため車体を修理する際などにステッカやシールを剥離しようとしても容易に剥離することができない上、無理に剥離しようとすると、車体や塗装を損傷する虞があると共に、車体に接着された内外装材を取り外した場合も、車体側に接着剤が粘着物として残るため、この粘着物も除去する必要があるが、粘着物は既に硬化しているため容易に除去することができない。
これら粘着物の除去に当たっては、まず電動ドリルやエアドリルのように手で持って作業が可能な回転駆動手段を利用して、回転駆動手段のチャック（ともに図示せず）に本体１の取り付け軸２を取り付け、取り付け軸２に設けられたテープ取り付け部材３に、作業に合わせて選択した幅の剥離部材５を取り付けるが、このとき剥離部材５のテープの巻き取り方向がテープ取り付け部材３の回転方向と逆になるように取り付ける。
すなわちテープ取り付け部材３が右方向へ回転する場合は、剥離部材５のテープの巻き取り方向が左方向となるように取り付けて、粘着物を剥離する際、剥離部材５の外周面に加わる摩擦力により粘着テープ５ｂが締付けられるようにする。そして加圧手段４の各ナット４ｂを締め上げて、押圧板４ａによりテープ取り付け部材３を軸方向より加圧し、テープ取り付け部材３の外周面を半径方向へ膨張させることにより、テープ取り付け部材３に対して剥離部材５を強固に取り付ける。
次にこの状態で回転駆動手段により取り付け軸２を回転させて、剥離部材５の外周面を剥離すべきステッカや、車体に固着した粘着物に押し当てるもので、剥離部材５の回転に伴いステッカや粘着物を剥離部材５の間に摩擦熱が発生してステッカの接着剤や粘着物を軟化させる。
同時に摩擦力により粘着テープ５ｂのテープ部分が削りカスとなって粘着テープ５ｂより脱落し、残った粘着面がステッカの軟化した接着剤や粘着物と結合して、車体より剥離すると共に、剥離されたステッカや粘着物は、テープの削りカスと共に固まりとなって脱落するため、従来のゴムや樹脂により形成されたローラにより剥離する場合と異なり、微細な摩耗粉が周囲に飛散することがない。
これによって作業環境が悪化することがないと共に、摩耗粉を作業者が吸い込む心配もないため作業者の健康を損なわれる心配もない。
またステッカの剥離や粘着物の除去が進むのに伴い粘着テープ５ｂは摩耗して外径が減少するので、粘着テープ５ｂがほとんどなくなったら、一旦作業を中断して粘着テープ５ｂを新たな粘着テープ５ｂと交換することにより、引き続き作業が続行できるため、車体の広い範囲に貼着されたステッカや、車体の広い範囲に残留する粘着物でも効率よく剥離除去することができるようになる。
そしてステッカや粘着物の除去が終了した際、車体に粘着テープの粘着剤や削りカス等が残留している場合は、ウエスにシリコンオフ等の揮発性液体を含ませて拭き取ればよい。
なお、作業の内容等により取り付け軸２の先端に螺装されたナット４ｂが車体を損傷する心配がある場合は、第３図に示す使用例のようにナット４ｂが剥離部材５の端面より突出しないように、予め粘着テープ５ｂの幅より長さの短いテープ取り付け部材３に粘着テープ５ｂを取り付けて作業すればよい。
一方第４図はテープ取り付け部材３の変形例を示すもので、この変形例では、テープ取り付け部材３をテーパ形状の２部材３ａ、３ｂより形成して、小径側端部が互いに対向するように取り付け軸２に取り付けた構造となっており、各テープ取り付け部材３ａ、３ｂのテーパ面３ｃで剥離部材５の芯体５ａ端部を支持する構造となっている。
前記変形例になる粘着物剥離装置による粘着物の除去方法は、前記実施の形態と同様なので説明は省略するが、各テープ取り付け部材３ａ、３ｂの間隔を調整することにより、芯材５ａの内径が異なる剥離部材５にも対応することができる。また第５図及び第６図は粘着物剥離装置の別の変形例を示すもので、この変形例では、加圧手段４の押圧板４ａの内面、すなわちテープ取り付け部材３の端面と当接する面に複数の突起４ｃを突設して、ナット４ｂを締め付けた際これら突起４ｃがテープ取り付け部材３の端面に食い込むようにしている。
さらにテープ取り付け部材３の両端面の角部を面取りして、面取り面３ｄを形成すると共に、テープ取り付け部材３の外周面に、取り付け軸２と平行する軸線方向に複数本の凹溝３ｅを円周方向に間隔を存して形成している。
前記変形例になる粘着物剥離装置による粘着物の除去方法も、前記実施の形態と同様なので説明は省略するが、加圧手段４のナット４ｂを締め付けた際、押圧板４ａより突設した突起４ｃがテープ取り付け部材３の端面に食い込むため、押圧板４ａとテープ取り付け部材３の間に滑りが生じることがない。
またテープ取り付け部材３の両端側に面取り面３ｄを形成した上、外周面に複数本の凹溝３ｅを形成したことにより、加圧手段４によりテープ取り付け部材３を加圧した際、テープ取り付け部材３が径方向へ膨張しやすくなるため、テープ取り付け部材３の外周面と剥離部材５の芯材５ａ内周面との接触面圧が上がって、テープ取り付け部材３より剥離部材５が外れにくくなることから、作業時の安全性が向上すると共に、剥離部材５を交換するためナット４ｂを緩めた際、テープ取り付け部材３が元の径に瞬時に収縮するため、剥離部材５を交換する作業が短時間で能率よく行えるようになる。
さらにテープ取り付け部材３の外周面に軸線方向に形成した複数の凹溝３ｅによって、テープ取り付け部材３の外周面と剥離部材５の芯材５ａの接触面積が少なくなる上、空気が侵入しやすくなるため、テープ取り付け部材３に剥離部材５をセットした状態で長期間放置しても、テープ取り付け部材３より剥離部材５が取り外ずせなくなることもない。
なお前記実施の形態及び変形例では、剥離部材５に紙テープよりなる粘着テープ５ｂを使用した例について説明したが、耐熱性があれば布テープや不織布テープ、樹脂テープ、コルクや皮等のシートをテープ状にしたものを使用してもよい。
産業上の利用可能性
以上詳述したように本発明の粘着物剥離除去装置は、取り付け軸に設けられたテープ取り付け部材に、粘着テープよりなる剥離部材を取り付けて、電動ドリルやエアドリルのような回転駆動手段により取り付け軸を回転させながら、剥離部材の外周面を剥離すべきステッカや、車体に固着した粘着物に押し当てることにより、ステッカや粘着物と剥離部材の間に摩擦熱が発生してステッカの接着剤や粘着物を軟化させ、同時に摩擦力により粘着テープの粘着面が接着剤や粘着物と結合して車体より剥離することができるため、車体に粘着したステッカや、車体に固着した粘着物を能率よく剥離することができる。
また剥離されたステッカや粘着物は、テープの削りカスと共に固まりとなって脱落するため、従来のゴムや樹脂により形成されたローラにより剥離する場合と異なり、微細な摩耗粉が周囲に飛散することがなく、これによって作業環境を悪化させたり、飛散した摩耗粉が作業者の目や鼻、口から体内に侵入して作業者の健康を損ねる等の従来の問題を解消することもできる。

BACKGROUND ART Conventionally, stickers and various interior and exterior materials are bonded to the body of an automobile by an adhesive such as an adhesive.
Since these stickers and interior / exterior materials are in the way of repairing or repainting the vehicle body, they are peeled off or removed from the vehicle body. Since removal requires a lot of time and labor, there is a problem that the work rate is very bad.
In order to improve this problem, for example, Japanese Utility Model Publication No. 8-9143 proposes a pressure-sensitive adhesive peeling rotary roll that peels and removes a sticker or the like adhered to a vehicle body or the like.
The pressure-sensitive adhesive peeling rotary roll disclosed in the above publication has a roll-shaped main body having elasticity and wear resistance on the surface thereof, and is rotated by an electric grinder or an air grinder and is pressure-bonded to the surface to be peeled. The pressure-sensitive adhesive is softened with frictional heat and peeled off.
However, the adhesive peeling rotary roll of the above publication has a solid structure in which a roll-shaped main body is formed of rubber or synthetic resin, and therefore, when the main body is pressed against the surface to be peeled, the main body is caused by friction between the main body and the surface to be peeled. Wears and generates a large amount of wear powder.
Since this wear powder is a fine powder, it is scattered to the surroundings as the roll-shaped main body rotates, and the working environment is deteriorated. Since it penetrates into the body from the eyes, nose and mouth, there are problems such as deteriorating the health of workers.
The present invention has been made in order to improve such conventional problems, and an object of the present invention is to provide an apparatus for removing and removing a sticky material in which fine wear powder does not scatter around.
DISCLOSURE OF THE INVENTION The present invention provides an adhesive peeling / removing device that peels and removes an adhesive adhered to a vehicle body or the like, an attachment shaft that is attached to a rotation driving means, a tape attachment member that is provided on the attachment shaft, and a detachable attachment to the tape attachment member Because it consists of a peeling member made of adhesive tape that is freely attached, and a pressurizing means that fixes the peeling member to the tape mounting member by pressing the tape mounting member in the axial direction, like an electric drill or air drill Friction heat is generated between the sticker or adhesive and the peeling member by rotating the mounting shaft with a simple rotation driving means and pressing the outer peripheral surface of the peeling member against the sticker to be peeled off or the adhesive stuck to the vehicle body To soften the sticker adhesive and adhesive, and at the same time, the adhesive surface of the adhesive tape is bonded to the adhesive and adhesive by the frictional force and peels off from the vehicle body. Since it is Rukoto, sticker and was sticking to the vehicle body, it can be peeled be efficiently stickies fixed to the vehicle body.
Also, since the peeled stickers and adhesives become solid with the shavings of the tape and fall off, unlike the case of peeling with a roller made of conventional rubber or resin, fine wear powder is scattered around. As a result, work efficiency deteriorates due to the deterioration of the work environment, and scattered abrasion powder penetrates into the body from the eyes, nose and mouth of the worker and damages the health of the worker. It can be solved.
Further, according to the present invention, the pressure plate is screwed to a screw plate formed on the mounting shaft and presses the pressure plate in the axial direction of the tape mounting member. Since it consists of a nut, the peeling member can be securely fixed to the tape mounting member simply by tightening the nut, so that the peeling member is idled during the work and the peeling work cannot be performed, and the work efficiency is reduced. In addition, there is no fear of this, and the operation of exchanging the worn release member with a new release member can be easily performed in a short time.
In addition, since a plurality of protrusions are provided on the surface of the pressing plate that contacts the end surface of the tape mounting member, when the pressing means is tightened, the protrusion protruding from the pressing plate bites into the end surface of the tape mounting member. Because no slip occurs between the pressing plate and the tape mounting member, and chamfered surfaces are formed at the corners on both ends of the tape mounting member, and a plurality of concave grooves are formed in the axial direction on the outer peripheral surface. When the tape attachment member 3 is pressurized by the pressurizing means, the tape attachment member easily expands in the radial direction, so that the contact surface pressure between the outer peripheral surface of the tape attachment member and the inner peripheral surface of the core member of the peeling member increases. Since the peeling member is less likely to come off than the tape attachment member, the safety during operation is improved.
Further, according to the present invention, the tape attachment member is formed from two members formed in a taper shape, and attached to the attachment shaft so that the small diameter side faces each other, and the core of the peeling member is held by the taper surface of the tape attachment member. Since it did so, since a peeling member can be attached to a tape attachment member even if the internal diameter of a core material changes, it can respond to the various peeling members from which an internal diameter differs.
In addition, since a heat-resistant masking tape, cloth tape, or the like is used for the peeling member, a consumable peeling member can be obtained at low cost.
BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail with reference to the drawings.
1 and FIG. 2 shows a main body 1 of an adhesive peeling device, which includes a mounting shaft 2 and a cylindrical tape mounting member 3 and a tape mounting member 3 made of an elastic body provided at one end of the mounting shaft 2. Comprises means 4 for pressurizing. A threaded portion 2a is formed on one end side of the mounting shaft 2, and the central portion of the tape mounting member 3 formed in a cylindrical shape by rubber or synthetic resin is searched for in the threaded portion 2a. A pair of pressing plates 4 a formed by washers having substantially the same diameter as the outer diameter of the tape attachment member 3 are in contact with both end surfaces of the tape 3.
The pressurizing means 4a is composed of the pressing plate 4a and a pair of nuts 4b screwed to the threaded portion 2a of the mounting shaft 2. The nuts 4b are tightened and the tape attaching member 3 is tightened by the pair of pressing means 4ab. The outer peripheral surface of the tape attachment member 3 can be expanded in the radial direction by pressurizing the end surface of the tape attachment member 2 in the axial direction of the attachment shaft 2.
During operation, the nut 4b is a double nut so that the nut 4b is not loosened, or the threaded portion 2a of the mounting shaft 2 is a reverse screw with respect to the rotational direction of the rotation drive means so that the nut 4b is tightened as the mounting shaft 2 rotates. May be.
On the other hand, the sticker bonded to the vehicle body and the peeling member 5 for peeling off the adhesive remaining on the vehicle body after the inner and outer materials are removed from the vehicle body are rolled into a cylindrical core body 5a and an outer periphery of the core body 5a. It consists of the wound adhesive tape 5b.
The core body 5a has an inner diameter slightly larger than the outer diameter of the tape mounting member 3 so that the tape mounting member 3 can be easily inserted into the core body 5a. When the member 3 is pressurized from the axial direction and the outer peripheral surface of the attachment member 3 is expanded in the radial direction, the inner surface of the core body 5a is in close contact with the outer peripheral surface of the tape attachment member 3, and the tape is attached by the frictional force of both. The peeling member 5 is prevented from idling with respect to the member 3.
For the adhesive tape 5b, a masking tape used for baking painting on the vehicle body or an equivalent product is used.
The masking tape is an adhesive tape 5b formed by applying a heat-resistant acrylic adhesive on at least one side of a tape material made of Japanese paper so that it can withstand the high temperatures during baking and painting. It can withstand high temperatures above ° C.
Moreover, the ready-made masking tape is standardized such that the width is, for example, 6 mm, 15 mm, 24 mm, and 30 mm, and the length of the mounting member 3 to which the peeling member 5 is attached is approximately 6 mm, 15 mm, and 24 mm according to these standards. 30 mm are prepared in advance.
Next, the operation of the pressure-sensitive adhesive peeling device constructed as described above will be described.
The stickers and seals attached to the car body are firmly adhered to the car body with a synthetic resin adhesive so that they cannot be easily peeled off. The interior material is attached to the inside of the car body, and is attached to the outside of the car body. Exterior materials such as moldings and side visors are firmly bonded to the vehicle body with a synthetic resin adhesive.
For this reason, when trying to remove the sticker or seal when repairing the vehicle body, it cannot be easily removed, and if you try to remove it forcibly, the vehicle body and paint may be damaged, and Even when the exterior material is removed, the adhesive remains as a sticky material on the vehicle body side. Therefore, it is necessary to remove this sticky material, but the sticky material has already been cured and cannot be easily removed.
In removing these adhesives, first, a rotary drive means that can be held by hand, such as an electric drill or an air drill, is used, and a mounting shaft 2 of the main body 1 is attached to a chuck (both not shown) of the rotary drive means. The peeling member 5 having a width selected according to the work is attached to the tape attachment member 3 provided on the attachment shaft 2. At this time, the winding direction of the tape of the separation member 5 is the rotation direction of the tape attachment member 3. Install so that it is the opposite.
That is, when the tape attachment member 3 rotates to the right, the frictional force applied to the outer peripheral surface of the peeling member 5 when the tape is wound so that the tape winding direction of the peeling member 5 is the left direction and the adhesive is peeled off. Thus, the adhesive tape 5b is tightened. And each nut 4b of the pressurization means 4 is tightened, the tape attachment member 3 is pressurized from the axial direction by the pressing plate 4a, and the outer peripheral surface of the tape attachment member 3 is expanded in the radial direction. On the other hand, the peeling member 5 is firmly attached.
Next, in this state, the mounting shaft 2 is rotated by the rotation driving means, and the outer peripheral surface of the peeling member 5 is pressed against the sticker to be peeled off or the adhesive material fixed to the vehicle body. Friction heat is generated between the peeling member 5 and the sticking material to soften the sticker adhesive and the sticking material.
At the same time, the tape portion of the adhesive tape 5b is scraped off by the frictional force and falls off from the adhesive tape 5b, and the remaining adhesive surface is combined with the softened adhesive or adhesive of the sticker and peeled off from the vehicle body. Since the sticker and the sticking material are lump together with the scraped scrap of the tape and fall off, unlike the case of peeling with a roller formed of conventional rubber or resin, fine wear powder does not scatter around.
As a result, the work environment is not deteriorated, and the operator's health is not impaired because the worker does not have to worry about sucking the wear powder.
Also, as the sticker is peeled off and the adhesive is removed, the adhesive tape 5b wears and the outer diameter decreases. Therefore, when the adhesive tape 5b is almost exhausted, the operation is temporarily suspended and the adhesive tape 5b is replaced with a new adhesive tape. By exchanging with 5b, the operation can be continued, so that even a sticker stuck on a wide range of the vehicle body or an adhesive remaining on the wide range of the vehicle body can be efficiently peeled and removed.
When the removal of the sticker or the adhesive is completed, if adhesive or shaving residue of the adhesive tape remains on the vehicle body, the waste may be wiped with a volatile liquid such as silicon off.
If there is a concern that the nut 4b screwed to the tip of the mounting shaft 2 may damage the vehicle body due to the contents of work, etc., the nut 4b protrudes from the end face of the peeling member 5 as in the use example shown in FIG. It is only necessary to attach the adhesive tape 5b to the tape attachment member 3 having a length shorter than the width of the adhesive tape 5b in advance.
On the other hand, FIG. 4 shows a modified example of the tape mounting member 3. In this modified example, the tape mounting member 3 is formed of two tapered members 3 a and 3 b so that the small diameter side ends face each other. It has a structure attached to the attachment shaft 2, and has a structure in which the end of the core 5a of the peeling member 5 is supported by the taper surface 3c of each tape attachment member 3a, 3b.
The method for removing the adhesive by the adhesive peeling device according to the modification is the same as that in the above embodiment, and thus the description thereof is omitted. However, by adjusting the interval between the tape attachment members 3a and 3b, the inner diameter of the core 5a is adjusted. However, it is possible to cope with the peeling members 5 having different values. 5 and 6 show another modified example of the pressure-sensitive adhesive peeling device. In this modified example, the inner surface of the pressing plate 4a of the pressing means 4, that is, the surface that comes into contact with the end surface of the tape attachment member 3 is shown. A plurality of protrusions 4 c are provided so as to protrude into the end face of the tape attachment member 3 when the nut 4 b is tightened.
Further, the corners of both end faces of the tape mounting member 3 are chamfered to form a chamfered surface 3d, and a plurality of concave grooves 3e are circularly formed on the outer peripheral surface of the tape mounting member 3 in the axial direction parallel to the mounting shaft 2. Formed at intervals in the circumferential direction.
The method for removing the sticky substance by the sticky substance peeling apparatus according to the modification is also the same as that of the above embodiment, so that the description thereof is omitted. However, when the nut 4b of the pressurizing means 4 is tightened, the protrusion protruding from the pressing plate 4a is provided. Since 4c bites into the end surface of the tape attachment member 3, no slip occurs between the pressing plate 4a and the tape attachment member 3.
Further, the chamfered surface 3d is formed on both end sides of the tape mounting member 3, and the plurality of concave grooves 3e are formed on the outer peripheral surface. Therefore, when the tape mounting member 3 is pressurized by the pressurizing means 4, the tape mounting member 3 becomes easy to expand in the radial direction, the contact surface pressure between the outer peripheral surface of the tape mounting member 3 and the inner peripheral surface of the core member 5a of the peeling member 5 is increased, and the peeling member 5 is less likely to come off from the tape mounting member 3. As a result, the safety during the work is improved, and when the nut 4b is loosened in order to replace the peeling member 5, the tape mounting member 3 is instantaneously contracted to the original diameter. It will be possible to do it efficiently in a short time.
Further, due to the plurality of concave grooves 3e formed in the axial direction on the outer peripheral surface of the tape mounting member 3, the contact area between the outer peripheral surface of the tape mounting member 3 and the core material 5a of the peeling member 5 is reduced, and air easily enters. Therefore, even if the peeling member 5 is set on the tape attachment member 3 and left for a long period of time, the peeling member 5 will not be removed from the tape attachment member 3.
In the embodiment and the modified example, the example in which the adhesive tape 5b made of a paper tape is used as the peeling member 5 has been described. However, if there is heat resistance, a sheet of cloth tape, nonwoven fabric tape, resin tape, cork, leather, or the like is used. A tape-shaped one may be used.
INDUSTRIAL APPLICABILITY As described in detail above, the pressure sensitive adhesive peeling and removing device of the present invention attaches a peeling member made of an adhesive tape to a tape mounting member provided on a mounting shaft, such as an electric drill or an air drill. While the mounting shaft is rotated by the rotation driving means, the outer peripheral surface of the peeling member is pressed against the sticker to be peeled off or the sticky material fixed to the vehicle body, so that frictional heat is generated between the sticker or the sticking material and the peeling member. The sticker's adhesive and adhesive can be softened, and at the same time, the adhesive surface of the adhesive tape can be bonded to the adhesive and adhesive and peeled off from the vehicle body by frictional force. The peeled adhesive can be peeled efficiently.
Also, since the peeled stickers and adhesives become solid with the shavings of the tape and fall off, unlike the case of peeling with a roller made of conventional rubber or resin, fine wear powder is scattered around. Therefore, it is possible to solve the conventional problems such as deteriorating the working environment and the scattered wear powder entering the body from the eyes, nose and mouth of the worker and deteriorating the health of the worker.
