Description

本発明は、任意の長さ及び幅を有する粘着テープを長手方向へ漸進的に物体の表面に貼り付けるための貼付装置に関する。   The present invention relates to a sticking device for sticking an adhesive tape having an arbitrary length and width to a surface of an object gradually in a longitudinal direction.

任意の長さ及び幅を有する基材の少なくとも片面に粘着剤層を備えた粘着テープを、その長手方向へ漸進的かつ連続的に、物体の表面に貼り付けるための貼付装置は、作業の負担を軽減しつつ作業時間を短縮できる手工具として、様々な分野で開発され、使用されている。例えば特許文献１は、自動車のドアの窓枠に塗装の代替物としての粘着テープを貼付するための貼付装置を開示する。この貼付装置は、窓枠を挟持する第１及び第２挟持片と、第１挟持片に支持され、粘着テープを窓枠の表面に押し付ける弾性ローラと、第２挟持片に支持され、窓枠の裏側に係合して貼付装置を窓枠に沿って案内するガイドローラとを備える。作業者は、第１及び第２挟持片を操作して弾性ローラとガイドローラとの間に窓枠を挟持するとともに、粘着面を窓枠表面側に向けた粘着テープの先端を窓枠表面と弾性ローラとの間に挿入し、その状態で、貼付装置を窓枠に沿って移動させることにより、弾性ローラからの押圧力下で粘着テープがその長手方向へ漸進的かつ連続的に窓枠表面に貼り付けられる。   A sticking device for sticking an adhesive tape having an adhesive layer on at least one side of a substrate having an arbitrary length and width to the surface of an object gradually and continuously in its longitudinal direction is a burden of work. It has been developed and used in various fields as a hand tool that can reduce the work time while reducing the amount of work. For example, Patent Document 1 discloses a sticking device for sticking an adhesive tape as a substitute for painting on a window frame of an automobile door. The sticking device includes first and second sandwiching pieces that sandwich the window frame, an elastic roller that is supported by the first sandwiching piece and presses the adhesive tape against the surface of the window frame, and a second sandwiching piece that is supported by the window frame. And a guide roller that engages with the back side of the guide and guides the sticking device along the window frame. The operator operates the first and second clamping pieces to sandwich the window frame between the elastic roller and the guide roller, and the tip of the adhesive tape with the adhesive surface facing the window frame surface side is set to the window frame surface. By inserting between the elastic rollers and moving the sticking device along the window frame in this state, the adhesive tape gradually and continuously moves in the longitudinal direction under the pressing force from the elastic rollers. Is pasted.

自動車のドアの窓枠のような所定の幅を有する物体表面に、塗装の代替物として粘着テープを貼り付ける用途では、粘着テープの幅寸法を物体表面の幅寸法よりも大きく成形し、粘着テープの長手方向へ延びる縁に沿った任意幅部分（本願で「粘着テープの縁部分」と称する）を物体の縁に沿って折り曲げて、物体の縁を粘着テープの縁部分で包み込むように貼り付けることが要求される場合がある。その場合には従来、例えば特許文献１に記載されるような貼付装置を用いて、幅広の粘着テープを自動車のドアの窓枠に貼付した後に、窓枠から張り出した粘着テープの縁部分を、スキージ等を用いて手作業により窓枠の縁に沿って折り曲げて窓枠の裏面にも貼付するようにしている。   In applications where adhesive tape is applied as an alternative to painting on an object surface with a predetermined width, such as the window frame of an automobile door, the width of the adhesive tape is formed to be larger than the width of the object surface. An arbitrary width portion along the edge extending in the longitudinal direction (referred to as an “adhesive tape edge portion” in this application) is bent along the edge of the object, and the object edge is attached so as to be wrapped by the edge portion of the adhesive tape. May be required. In that case, after pasting a wide adhesive tape on a window frame of an automobile door, for example, using a pasting device as described in Patent Document 1, for example, the edge portion of the adhesive tape protruding from the window frame is used. A squeegee or the like is used to manually fold it along the edge of the window frame and attach it to the back of the window frame.

上記した粘着テープの縁曲げ作業は、粘着テープの粘着面と物体表面との間の空気を排除しながら貼り付けることが望まれるので、作業の熟練を要するだけでなく、作業時間が増加する傾向がある。そこで、例えば特許文献２に開示されるように、物体表面に貼付された粘着テープの縁部分を、物体の縁に沿って自動的に折り曲げて、物体裏面に貼り付けることができる貼付装置が提案されている。   The edge bending work of the above-mentioned adhesive tape is desired to be applied while eliminating air between the adhesive surface of the adhesive tape and the object surface. There is. Therefore, as disclosed in Patent Document 2, for example, a sticking device is proposed that can automatically bend the edge portion of the adhesive tape attached to the surface of the object along the edge of the object and attach it to the back of the object. Has been.

特許文献２に開示される貼付装置は、自動車のドアの窓枠のような所定の幅を有する物体を、それぞれに対を成す複数組のガイドローラの間に受容した状態で、物体に沿って移動できるように構成される。各組を成す一対のガイドローラは、物体の両縁のそれぞれに当接される外周面を有して、互いに独立して回転可能に装置本体に支持される。複数組のガイドローラは、装置本体に対する物体及び物体表面に貼付された粘着テープの送り方向に見て、上流端の一対のガイドローラ、中間の一対のガイドローラ、及び下流端の一対のガイドローラを含む。上流端のガイドローラ対は、それらの外周面が物体表面に対し鋭角を成すように配置され、中間のガイドローラ対は、それらの外周面が物体の縁に平行に向くように配置され、下流端のガイドローラ対は、それらの外周面が物体裏面に沿うように配置される。これら複数組のガイドローラの間に、表面に粘着テープを貼付した物体を受容して、装置本体を物体に沿って移動させることにより、粘着テープの両縁部分が、粘着面と物体表面との間の空気を排除しながら、物体の両縁に沿って次第に深く折り込まれ、最終的に物体両縁を包み込んで物体裏面に貼付される。   The sticking device disclosed in Patent Document 2 is arranged along an object in a state where an object having a predetermined width such as a window frame of a car door is received between a plurality of pairs of guide rollers. Configured to be movable. The pair of guide rollers forming each set has outer peripheral surfaces that are in contact with both edges of the object, and are supported by the apparatus main body so as to be rotatable independently of each other. The plurality of sets of guide rollers are a pair of guide rollers at the upstream end, a pair of guide rollers at the intermediate end, and a pair of guide rollers at the downstream end as viewed in the feeding direction of the object and the adhesive tape attached to the object surface with respect to the apparatus main body. including. The guide roller pair at the upstream end is arranged so that their outer peripheral surfaces form an acute angle with respect to the object surface, and the intermediate guide roller pair is arranged so that their outer peripheral surfaces are oriented parallel to the edge of the object, and downstream The end guide roller pairs are arranged such that their outer peripheral surfaces are along the object back surface. By receiving an object having an adhesive tape affixed to the surface between the plurality of sets of guide rollers and moving the apparatus main body along the object, both edge portions of the adhesive tape are connected between the adhesive surface and the object surface. While excluding the air in between, it is gradually folded deeper along both edges of the object, and finally wrapped around both edges of the object and attached to the back of the object.

上記したように、所定の幅を有する物体表面に、任意長さの粘着テープを、物体の縁を粘着テープの縁部分で包み込むように貼り付ける場合には、幅広の粘着テープの中央部分を物体表面に貼付する段階と、物体から張り出した粘着テープの縁部分を折り曲げて物体裏面に貼付する段階との、大別して２段階の作業が必要となる。これら２段階の作業を、全てスキージ等を用いた手作業で行なおうとすると、作業の熟練を要することはもちろん、作業時間が著しく長くなる傾向がある。特に、粘着テープの縁部分を物体の縁に沿って折り曲げる縁曲げ作業は、作業中に手を負傷しないように注意を払う必要が有るので、作業者の負担が増す。他方、これら２段階の作業を、それぞれの作業に特化した２種類の貼付装置を用いて順次実施する場合には、貼付作業自体は容易になるものの、個々の貼付装置の物体に対する位置決め等の段取りに時間を消費し、結果として、作業時間をさほど短縮できないことが懸念される。   As described above, when sticking an adhesive tape of an arbitrary length on the surface of an object having a predetermined width so that the edge of the object is wrapped by the edge of the adhesive tape, the center part of the wide adhesive tape is attached to the object. There are roughly two stages of operations: the step of attaching to the front surface and the step of bending the edge portion of the adhesive tape protruding from the object and applying it to the back surface of the object. If these two stages of work are all performed manually using a squeegee or the like, not only skill of the work is required, but the work time tends to be remarkably long. In particular, the edge bending operation for bending the edge portion of the adhesive tape along the edge of the object needs to pay attention so as not to injure the hand during the operation, which increases the burden on the operator. On the other hand, when these two stages of work are sequentially performed using two types of sticking devices specialized for each work, the sticking work itself is facilitated, but positioning of the individual sticking devices with respect to the object, etc. There is a concern that time will be consumed for setup, and as a result, the working time cannot be reduced so much.

本発明の目的は、任意の長さ及び幅を有する粘着テープを長手方向へ漸進的に物体の表面に貼り付けるための貼付装置において、１つの貼付装置で、かつ１回の貼付作業で、粘着テープの縁部分を物体の縁に沿って自動的に折り曲げながら粘着テープを物体表面に貼付でき、作業者の負担を軽減できる縁曲げ貼付装置を提供することにある。   An object of the present invention is to provide an adhesive device for adhering an adhesive tape having an arbitrary length and width to the surface of an object gradually in the longitudinal direction, with one application device and one application operation. An object of the present invention is to provide an edge bend application device that can apply an adhesive tape to the surface of an object while automatically bending the edge of the tape along the edge of the object, thereby reducing the burden on the operator.

Between the first member 22 and the second member 26, an elastic member 36 (for example, a torsion coil spring) that elastically biases the second member 26 toward the closed position is installed.

後述するように、各ガイドローラ３２は、第２部材２６が閉位置にあるときに、溝形外周面３４と圧着部材１６の第１当接面１４との間に弾性部材３６の付勢力下で物体Ｏを挟持するとともに、溝形外周面３４が物体Ｏの表面Ｓとは反対側の裏面構造に係合して、テープ貼付作業中に貼付装置１０を物体Ｏに沿って粘着テープＴの送り方向Ｄとは逆の方向へ案内するように作用する。また、第２部材２６が開位置にあるときには、各ガイドローラ３２の溝形外周面３４と圧着部材１６の第１当接面１４との間が開放され、貼付装置１０を物体Ｏに容易に着脱できるようになる。なお、第２部材２６にはさらに、物体Ｏの裏面構造に同様に係合して補助的な案内作用を発揮する一対の補助ガイドローラ３８が、送り方向Ｄに沿った並列配置で互いに独立して回動自在に支持される。   As will be described later, each guide roller 32 is under the urging force of the elastic member 36 between the groove-shaped outer peripheral surface 34 and the first contact surface 14 of the crimping member 16 when the second member 26 is in the closed position. And the groove-shaped outer peripheral surface 34 engages with the back surface structure opposite to the surface S of the object O, and the sticking device 10 is moved along the object O during the tape sticking operation. It acts to guide in the direction opposite to the feed direction D. When the second member 26 is in the open position, the gap between the groove-shaped outer peripheral surface 34 of each guide roller 32 and the first contact surface 14 of the pressure-bonding member 16 is opened, so that the sticking device 10 can be easily attached to the object O. Detachable. The second member 26 further includes a pair of auxiliary guide rollers 38 that similarly engage with the back surface structure of the object O and exhibit an auxiliary guiding action, and are arranged independently in a parallel arrangement along the feeding direction D. And is supported rotatably.

第３部材３０は、第１部材２２を中心に第２部材２６とは反対側に配置される。第３部材３０には、一対のガイドローラ３２とは反対側で圧着部材１６の第１当接面１４に対向配置可能なテープ規制面４０が設けられる。第３部材３０は、軸２８を中心として第１部材２２に対し回動する（図３矢印β）ことにより、テープ規制面４０が圧着部材１６の第１当接面１４に所定の隙間を介して最接近する閉位置（図３）と、テープ規制面４０が圧着部材１６の第１当接面１４から十分に離隔する開位置との間で変位する。第１部材２２と第３部材３０との間には、第３部材３０を閉位置に向けて弾性的に付勢する弾性部材４２（例えばねじりコイルばね）が設置される。   The third member 30 is disposed on the opposite side to the second member 26 with the first member 22 as the center. The third member 30 is provided with a tape regulating surface 40 that can be disposed opposite to the first contact surface 14 of the crimping member 16 on the side opposite to the pair of guide rollers 32. The third member 30 rotates about the shaft 28 with respect to the first member 22 (arrow β in FIG. 3), so that the tape restricting surface 40 passes through the first contact surface 14 of the crimping member 16 with a predetermined gap. The closed position (FIG. 3) that is closest and the open position where the tape regulating surface 40 is sufficiently separated from the first contact surface 14 of the crimping member 16. An elastic member 42 (for example, a torsion coil spring) that elastically biases the third member 30 toward the closed position is installed between the first member 22 and the third member 30.

後述するように、第３部材３０は、閉位置にあるときに、テープ規制面４０と圧着部材１６の第１当接面１４との間の隙間に、離型紙Ｒ（図２及び図５）付きの粘着テープＴを、その送り動作を妨害することなく、送り中の姿勢変動を抑制しつつ位置決めするように作用する。また、第３部材３０が開位置にあるときには、テープ規制面４０と圧着部材１６の第１当接面１４との間が開放され、粘着テープＴを貼付装置１０上で所定の初期位置に容易にセッティングできるようになる。なお、第３部材３０のテープ規制面４０と圧着部材１６の第１当接面１４との間の隙間を通過した離型紙Ｒ付きの粘着テープＴは、第１当接面１４を取り巻いて、圧着部材１６と第２部材２６上のガイドローラ３２との間の隙間に送られる。この間、後述するように、離型紙Ｒが粘着テープＴから自動的に剥離され、本体１２の外部に排出される。その目的で、本体１２の第１部材２２には、圧着部材１６に近接して、離型紙Ｒを粘着テープＴから円滑に剥離させるためのテンション部材としての剥離棒４４と、離型紙Ｒを本体１２から障害無く排出するための逃がし面４６ａを有する排出板４６とが設置される。   As will be described later, when the third member 30 is in the closed position, the release paper R (FIGS. 2 and 5) is placed in the gap between the tape regulating surface 40 and the first contact surface 14 of the crimping member 16. The attached adhesive tape T acts to position the adhesive tape T while suppressing fluctuations in posture during feeding without interfering with the feeding operation. Further, when the third member 30 is in the open position, the space between the tape regulating surface 40 and the first contact surface 14 of the crimping member 16 is opened, and the adhesive tape T can be easily placed on the pasting device 10 at a predetermined initial position. Can be set to The adhesive tape T with release paper R that has passed through the gap between the tape regulating surface 40 of the third member 30 and the first contact surface 14 of the pressure-bonding member 16 surrounds the first contact surface 14. It is sent to the gap between the crimping member 16 and the guide roller 32 on the second member 26. During this time, as will be described later, the release paper R is automatically peeled off from the adhesive tape T and discharged to the outside of the main body 12. For this purpose, the first member 22 of the main body 12 is provided with a release rod 44 as a tension member for smoothly releasing the release paper R from the adhesive tape T in the vicinity of the pressure-bonding member 16 and the release paper R. 12 and a discharge plate 46 having a relief surface 46a for discharging without any obstacle.

なお、本体１２を構成する第１部材２２、第２部材２６及び第３部材３０は、全体としてプラスチック、金属等の硬質素材から作製されることが、粘着テープＴを物体Ｏの表面Ｓ及び縁Ｅに正確に追従させて貼り付ける観点で有利である。   The first member 22, the second member 26, and the third member 30 constituting the main body 12 are made of a hard material such as plastic or metal as a whole, and the adhesive tape T is attached to the surface S and the edge of the object O. This is advantageous from the viewpoint of pasting E accurately.

圧着部材１６は、本体１２の第１部材２２に回動可能に設置される１つの圧着ローラ４８を備え、この圧着ローラ４８に、粘着テープＴの中央部分Ｃに当接可能な円筒状の第１当接面１４が設けられる。圧着ローラ４８は、本体１２の第１部材２２に取り付けられた軸５０に支持され、それにより、第１当接面１４の中心線となる圧着ローラ４８の回転軸線４８ａが規定される。圧着ローラ４８は、少なくとも第１当接面１４を含む部分が、物体Ｏの表面Ｓの形状に追従して変形可能な可撓性を有する材料から作製される。圧着ローラ４８のこのような可撓性材料としては、ウレタンゴム、シリコンゴム、天然ゴム等を好適に使用できる。なお、本体１２の第１部材２２と第２部材２６とを連結する軸２４、及び第１部材２２と第３部材３０とを連結する軸２８はいずれも、圧着ローラ４８の回転軸線４８ａに略直交する軸線を有する。また、第１部材２２に設置した剥離棒４４は、圧着ローラ４８の回転軸線４８ａに略平行な軸線４４ａを有する（図３）。   The pressure-bonding member 16 includes a pressure-bonding roller 48 that is rotatably installed on the first member 22 of the main body 12, and the pressure-bonding roller 48 has a cylindrical first shape that can contact the central portion C of the adhesive tape T. One abutment surface 14 is provided. The pressure roller 48 is supported by a shaft 50 attached to the first member 22 of the main body 12, thereby defining a rotation axis 48 a of the pressure roller 48 serving as the center line of the first contact surface 14. The pressure roller 48 is made of a flexible material in which at least a portion including the first contact surface 14 can be deformed following the shape of the surface S of the object O. As such a flexible material for the pressure roller 48, urethane rubber, silicon rubber, natural rubber or the like can be suitably used. Note that the shaft 24 that connects the first member 22 and the second member 26 of the main body 12 and the shaft 28 that connects the first member 22 and the third member 30 are both substantially aligned with the rotation axis 48 a of the pressure roller 48. It has an orthogonal axis. Further, the peeling bar 44 installed on the first member 22 has an axis 44a substantially parallel to the rotation axis 48a of the pressure roller 48 (FIG. 3).

圧着部材１６を圧着ローラ４８から構成することにより、後述する漸進的テープ貼付作業に際して、圧着部材１６が粘着テープＴの表面に及ぼす損傷を低減できるとともに、圧着部材１６の寿命を向上させることができる。ここで、圧着ローラ４８の上記可撓性材料の硬度を選択することにより、物体Ｏの表面Ｓの形状に対する第１当接面１４の追従性を最適化して、表面Ｓに貼付された粘着テープＴの、基材の皺や粘着面への空気取り込みを効果的に防止することができる。このような観点で、圧着ローラ４８の好適な硬度は、２０〜９０（ショアＡ硬度）である。なお、適用対象の粘着テープＴ及び物体Ｏの物性によっては、固定式の圧着部材１６を使用することもできる。   By constituting the pressure-bonding member 16 from the pressure-bonding roller 48, damage to the surface of the pressure-sensitive adhesive tape T by the pressure-bonding member 16 can be reduced and the life of the pressure-bonding member 16 can be improved. . Here, by selecting the hardness of the flexible material of the pressure roller 48, the followability of the first contact surface 14 with respect to the shape of the surface S of the object O is optimized, and the adhesive tape affixed to the surface S It is possible to effectively prevent T from taking in air into the wrinkles of the base material and the adhesive surface. From such a viewpoint, the suitable hardness of the pressure roller 48 is 20 to 90 (Shore A hardness). Depending on the physical properties of the target adhesive tape T and the object O, a fixed crimp member 16 can be used.

縁曲げ部材２０は、本体１２の第１部材２２に回動可能に設置される一対の縁曲げローラ５２を備え、それら縁曲げローラ５２のそれぞれに、粘着テープＴの両側の縁部分Ｍに個々に当接可能な断面凹形の環状の第２当接面１８が設けられる。それら縁曲げローラ５２は、互いに独立して回動可能である。また、それら縁曲げローラ５２は、本体１２の第１部材２２に変位可能に取り付けられた軸５４に支持され、それにより、第２当接面１８の中心線となる両縁曲げローラ５２の回転軸線５２ａが規定される。各縁曲げローラ５２は、少なくとも第２当接面１８を含む部分が、物体Ｏの縁Ｅの輪郭に追従して変形可能な可撓性を有する材料から作製される。縁曲げローラ５２のこのような可撓性材料としては、ウレタンゴム、シリコンゴム、天然ゴム等を好適に使用できる。   The edge bending member 20 includes a pair of edge bending rollers 52 that are rotatably installed on the first member 22 of the main body 12, and each of the edge bending rollers 52 is individually connected to the edge portions M on both sides of the adhesive tape T. An annular second abutting surface 18 having a concave cross section that can abut against the second is provided. The edge bending rollers 52 can be rotated independently of each other. The edge bending rollers 52 are supported by a shaft 54 that is displaceably attached to the first member 22 of the main body 12, thereby rotating the both edge bending rollers 52 serving as the center line of the second contact surface 18. An axis 52a is defined. Each edge bending roller 52 is made of a flexible material that can deform at least a portion including the second contact surface 18 following the contour of the edge E of the object O. As such a flexible material for the edge bending roller 52, urethane rubber, silicon rubber, natural rubber or the like can be suitably used.

縁曲げ部材２０を一対の縁曲げローラ５２から構成することにより、後述する粘着テープＴの漸進的貼付作業に際して、粘着テープＴの両縁部分Ｍを１回の貼付作業で同時に折り曲げることができる。また、物体Ｏの表面Ｓが曲線状に延びる場合にも、それら縁曲げローラ５２が互いに独立して回動することにより、物体Ｏの両縁Ｅの例えば湾曲領域における長さの差を吸収して、粘着テープＴの両縁部分Ｍを物体両縁Ｅに沿って安定的に折り曲げることができる。しかも、回転可能な縁曲げローラ５２からなる縁曲げ部材２０は、粘着テープＴの表面に及ぼす損傷を低減できるとともに、縁曲げ部材２０自体の寿命を向上させることができる。   By constituting the edge bending member 20 from a pair of edge bending rollers 52, both edge portions M of the adhesive tape T can be simultaneously bent by a single application operation when the adhesive tape T is gradually applied. Further, even when the surface S of the object O extends in a curved shape, the edge bending rollers 52 rotate independently of each other, thereby absorbing a difference in length of, for example, the curved regions of both edges E of the object O. Thus, both edge portions M of the adhesive tape T can be stably bent along the object both edges E. In addition, the edge bending member 20 including the rotatable edge bending roller 52 can reduce damage to the surface of the adhesive tape T and can improve the life of the edge bending member 20 itself.

ここで、各縁曲げローラ５２の上記可撓性材料の硬度を選択することにより、物体Ｏの縁Ｅの輪郭に対する第２当接面１８の追従性を最適化して、縁Ｅに貼付された粘着テープＴの、基材の皺や粘着面への空気取り込みを効果的に防止することができる。このような観点で、縁曲げローラ５２の好適な硬度は、２０〜９０（ショアＡ硬度）である。なお、適用対象の粘着テープＴ及び物体Ｏの物性によっては、固定式の縁曲げ部材２０を使用することもできる。また、粘着テープＴの一方の縁部分Ｍのみを縁曲げすることが要求される場合には、縁曲げ部材２０は１つの第２当接面１８を有していれば良い。   Here, by selecting the hardness of the flexible material of each edge bending roller 52, the followability of the second abutting surface 18 with respect to the contour of the edge E of the object O is optimized, and affixed to the edge E. Air intake of the adhesive tape T to the wrinkles and adhesive surface of the base material can be effectively prevented. From such a viewpoint, the suitable hardness of the edge bending roller 52 is 20 to 90 (Shore A hardness). Depending on the physical properties of the target adhesive tape T and the object O, the fixed edge bending member 20 can be used. When it is required to bend only one edge portion M of the adhesive tape T, the edge bending member 20 only needs to have one second contact surface 18.

一対の縁曲げローラ５２の形状は、互いに同一でも良いし、図示実施形態のように互いに異なっていても良い。例えば、縁曲げローラ５２の円筒部分の軸線方向寸法は、縁曲げ対象となる粘着テープＴの縁部分Ｍの幅方向寸法に対応して設定できる。また、第２当接面１８の形状は、後述するように、粘着テープＴの縁部分Ｍを中央部分Ｃに対し約９０度まで折り曲げることができる形状であって、物体Ｏの表面Ｓに対する縁Ｅの表面の角度等に依存して最適な形状を選定できる。   The shape of the pair of edge bending rollers 52 may be the same as each other, or may be different from each other as in the illustrated embodiment. For example, the axial direction dimension of the cylindrical part of the edge bending roller 52 can be set corresponding to the width direction dimension of the edge part M of the adhesive tape T to be edge bent. The shape of the second contact surface 18 is a shape that allows the edge portion M of the adhesive tape T to be bent to about 90 degrees with respect to the central portion C, as will be described later. An optimum shape can be selected depending on the angle of the surface of E and the like.

本体１２の第１部材２２には、縁曲げ部材２０を構成する一対の縁曲げローラ５２の軸５４を変位可能に受容する一対の長穴５６が設けられる。各長穴５６は、その長軸を、テープ貼付作業中に物体Ｏに貼付されて送り方向Ｄへ送られる粘着テープＴに対し、略直交する方向へ向けて形成される（図２）。図６に断面で示すように、第１部材２２に形成した一対の長穴５６は、軸５４の両端近傍部位５４ａを個々に、長軸に沿った方向（図２矢印γ）へ互いに独立して摺動可能に受容する。したがって軸５４は、縁曲げローラ５２の回転軸線５２ａが、圧着部材１６を構成する圧着ローラ４８の回転軸線４８ａに対し平行な姿勢と任意角度だけ傾斜する姿勢との間で、自在に変位できる。   The first member 22 of the main body 12 is provided with a pair of elongated holes 56 that receive the shafts 54 of the pair of edge bending rollers 52 constituting the edge bending member 20 in a displaceable manner. Each long hole 56 is formed so that its long axis is directed in a direction substantially orthogonal to the adhesive tape T that is stuck to the object O and sent in the feeding direction D during the tape sticking operation (FIG. 2). As shown in cross section in FIG. 6, the pair of long holes 56 formed in the first member 22 are independent of each other in the vicinity of both ends 54 a of the shaft 54 in the direction along the long axis (arrow γ in FIG. 2). And slidably received. Therefore, the shaft 54 can be freely displaced between the posture in which the rotation axis 52a of the edge bending roller 52 is parallel to the rotation axis 48a of the pressure roller 48 constituting the pressure member 16 and the posture inclined by an arbitrary angle.

各縁曲げローラ５２は、軸５４に、軸線方向へ変位可能に支持される。両縁曲げローラ５２には、それら縁曲げローラ５２を軸５４に沿って互いに離れる方向へ弾性的に付勢する付勢部材５８が付設される。図示実施形態では付勢部材５８は、両縁曲げローラ５２の間で軸５４を取り巻くように装着される圧縮コイルばねから構成される（図１）。さらに、軸５４は、本体１２の第１部材２２から外方へ突出する延長部６０を両端に有し、それら延長部６０のそれぞれに、一対の縁曲げローラ５２を本体１２に対して軸線方向又は軸線に交差する方向へ変位させるためのハンドル６２が設けられる。   Each edge bending roller 52 is supported by the shaft 54 so as to be displaceable in the axial direction. The both edge bending rollers 52 are provided with urging members 58 that elastically urge the edge bending rollers 52 in directions away from each other along the shaft 54. In the illustrated embodiment, the urging member 58 is composed of a compression coil spring mounted so as to surround the shaft 54 between the two edge bending rollers 52 (FIG. 1). Further, the shaft 54 has extension portions 60 projecting outward from the first member 22 of the main body 12 at both ends, and a pair of edge bending rollers 52 are axially arranged with respect to the main body 12 in each of the extension portions 60. Alternatively, a handle 62 is provided for displacement in a direction that intersects the axis.

図５に示すように、貼付装置１０を適用可能な粘着テープＴは、樹脂、布帛、紙等の適当な材料からなる基材Ｂと、基材Ｂの片面に積層される粘着剤層Ａとを備え、粘着剤層Ａに離型紙Ｒを被着した状態で、貼付装置１０に供給される（図５（ａ））。貼付装置１０は、離型紙Ｒを粘着テープＴから自動的に剥離して粘着剤層Ａを露出させ、圧着部材１６により粘着テープＴの中央部分Ｃを物体Ｏの表面Ｓに貼付するとともに、縁曲げ部材２０により粘着テープＴの両縁部分Ｍを物体Ｏの両縁Ｅに沿って、中央部分Ｃに対し約９０度の角度に自動的に折り曲げる（図５（ｂ））。特に、図４に示す適用例では、自動車のドアフレームからなる物体Ｏにおいて、略一様な幅を有する傾斜枠部分Ｆ１に、ドアフレームに対応する形状に成形された粘着テープＴの、略一様な幅を有する斜辺領域Ｔ１を貼付するために、好適に使用される。以下、貼付装置１０を用いた粘着テープ貼付作業を、図４及び図５の適用例に関連して説明する。   As shown in FIG. 5, the adhesive tape T to which the sticking device 10 can be applied includes a base material B made of an appropriate material such as resin, fabric, paper, and the like, and an adhesive layer A laminated on one side of the base material B. And is supplied to the sticking device 10 with the release paper R attached to the adhesive layer A (FIG. 5A). The attaching device 10 automatically peels the release paper R from the adhesive tape T to expose the adhesive layer A, and attaches the central portion C of the adhesive tape T to the surface S of the object O by the pressure-bonding member 16. The bending member 20 automatically bends both edge portions M of the adhesive tape T along the both edges E of the object O at an angle of about 90 degrees with respect to the central portion C (FIG. 5B). In particular, in the application example shown in FIG. 4, in the object O composed of an automobile door frame, the adhesive tape T formed into a shape corresponding to the door frame is formed on the inclined frame portion F1 having a substantially uniform width. It is preferably used for attaching the hypotenuse region T1 having such a width. Hereinafter, the adhesive tape sticking operation using the sticking device 10 will be described with reference to the application examples of FIGS. 4 and 5.

まず準備段階として、ドアフレームに対応する形状に成形された粘着テープＴの、貼付作業始端であるコーナー部に形成したフック片ＴＳを、貼付装置１０の本体１２に係合させて仮留めし、粘着テープＴの斜辺領域Ｔ１を、離型紙Ｒと共に本体１２の送り経路Ｐに沿わせて配置する。このとき、本体１２の第１部材２２に対して第３部材３０を（好ましくは第２部材２６も）開位置に置くことにより、粘着テープＴの斜辺領域Ｔ１を、圧着部材１６（圧着ローラ４８）とガイドローラ３２との間の隙間、及び圧着部材１６とテープ規制面４０との間の隙間に、容易に配置することができる。なお、本体１２の第１部材２２には、粘着テープＴのフック片ＴＳを仮留めするためのスロット６４（図６）及び挟持片６６（図２）が設けられている。   First, as a preparatory stage, the hook piece TS formed in the corner portion which is the starting end of the sticking operation of the adhesive tape T formed in a shape corresponding to the door frame is engaged with the main body 12 of the sticking device 10 and temporarily fixed. The hypotenuse region T1 of the adhesive tape T is arranged along the feed path P of the main body 12 together with the release paper R. At this time, the third member 30 (preferably also the second member 26) is placed in the open position with respect to the first member 22 of the main body 12, whereby the hypotenuse region T1 of the adhesive tape T is moved to the pressure member 16 (pressure roller 48). ) And the guide roller 32 and in the gap between the crimping member 16 and the tape regulating surface 40 can be easily arranged. The first member 22 of the main body 12 is provided with a slot 64 (FIG. 6) and a clamping piece 66 (FIG. 2) for temporarily fastening the hook piece TS of the adhesive tape T.

本体１２の送り経路Ｐに粘着テープＴを適正に配置した状態で、離型紙Ｒはガイドローラ３２及びテープ規制面４０に対向して配置される。このとき、例えばフック片ＴＳの近傍で予め離型紙Ｒに切り込みを設けておき、その切り込みに後続する離型紙Ｒを、本体１２上の剥離棒４４（図２）に近接する位置まで意図的に部分剥離する。そして、離型紙Ｒの剥離端を、本体１２上の排出板４６の逃がし面４６ａ（図２）に載せておく。これにより、本体１２に対する粘着テープＴの初期セッティングが完了する。   With the adhesive tape T properly disposed in the feed path P of the main body 12, the release paper R is disposed to face the guide roller 32 and the tape regulating surface 40. At this time, for example, a cut is provided in the release paper R in the vicinity of the hook piece TS, and the release paper R subsequent to the cut is intentionally moved to a position close to the peeling bar 44 (FIG. 2) on the main body 12. Partially peel off. Then, the peeling end of the release paper R is placed on the escape surface 46 a (FIG. 2) of the discharge plate 46 on the main body 12. Thereby, the initial setting of the adhesive tape T with respect to the main body 12 is completed.

次に、操作者は、前述したように本体１２の第２部材２６を第１部材２２に対し回動操作して、一対のガイドローラ３２を圧着ローラ４８から十分に離隔させ、その状態で、圧着ローラ４８とガイドローラ３２との間に、ドアフレームを構成する物体Ｏのコーナー領域ＯＣ（図４）を挿入する。そして、弾性部材３６のばね力下で第２部材２６を閉位置に復帰させ、物体Ｏのコーナー領域ＯＣを、本体１２上で初期セッティングした粘着テープＴのフック片ＴＳの近傍領域と共に、圧着ローラ４８と両ガイドローラ３２との間に挟持する。このとき、両ガイドローラ３２がその溝形外周面３４で、物体Ｏの裏面構造として傾斜枠部分Ｆ１に沿って延設されたリブＦＲ（図７）に転動可能に係合する。同時に、第２部材２６上の一対の補助ガイドローラ３８が、物体Ｏの裏面構造として傾斜枠部分Ｆ１に沿って延設された延長面ＦＥ（図７）に転動可能に係合する。このようにして、貼付装置１０が物体Ｏ上で、テープ貼付作業開始位置に自立式に保持される。なお、図７及び図８は、テープ貼付作業開始位置に配置された貼付装置１０と物体Ｏとの相対的位置関係を、初期セッティングした粘着テープＴを省略して示す。   Next, the operator rotates the second member 26 of the main body 12 with respect to the first member 22 as described above to sufficiently separate the pair of guide rollers 32 from the pressure roller 48, and in this state, Between the pressure roller 48 and the guide roller 32, the corner area OC (FIG. 4) of the object O constituting the door frame is inserted. Then, the second member 26 is returned to the closed position under the spring force of the elastic member 36, and the corner region OC of the object O together with the region near the hook piece TS of the adhesive tape T that is initially set on the main body 12 is pressed. It is clamped between 48 and both guide rollers 32. At this time, both guide rollers 32 engage with a rib FR (FIG. 7) extending along the inclined frame portion F1 as the back surface structure of the object O at the groove-shaped outer peripheral surface 34. At the same time, the pair of auxiliary guide rollers 38 on the second member 26 engage with an extended surface FE (FIG. 7) extending along the inclined frame portion F1 as the back surface structure of the object O so as to be able to roll. In this manner, the sticking device 10 is held on the object O in a self-supporting manner at the tape sticking work start position. 7 and 8 show the relative positional relationship between the sticking device 10 arranged at the tape sticking work start position and the object O, omitting the initially set adhesive tape T. FIG.

この作業開始位置から、操作者は貼付装置１０の本体１２を握持して、本体１２を物体Ｏの傾斜枠部分Ｆ１に沿って、圧着部材１６（圧着ローラ４８）が先導側で縁曲げ部材２０（縁曲げローラ５２）が後続側となる方向（図８矢印Ｄ´）へ、連続的に移動させる。それに伴い、本体１２上の送り経路Ｐ内で初期セッティングされていた粘着テープＴは、その中央部分Ｃが圧着ローラ４８の第１当接面１４から押圧力を受けて、離型紙Ｒを剥がした領域から長手方向へ漸進的に傾斜枠部分Ｆ１の表面Ｓに貼付される。このとき、圧着ローラ４８は、傾斜枠部分Ｆ１の表面Ｓの形状に追従して弾性変形し、それにより粘着テープＴの中央部分Ｃを、その皺や粘着剤層Ａと物体表面Ｓとの間への空気取込みを効率良く排除しながら、物体表面Ｓに貼付するように作用する。圧着ローラ４８から粘着テープＴに加わる押圧力は、操作者が本体１２の移動操作中に意図的に加えることもできるが、第２部材２６に作用する弾性部材３６の弾性的付勢力によって、安定的に確保される。   From this work start position, the operator grips the main body 12 of the sticking device 10 and holds the main body 12 along the inclined frame portion F1 of the object O so that the pressure bonding member 16 (pressure bonding roller 48) is the edge bending member on the leading side. 20 (edge bending roller 52) is continuously moved in the direction (arrow D ′ in FIG. 8) on the subsequent side. Accordingly, the adhesive tape T that was initially set in the feeding path P on the main body 12 received the pressing force from the first contact surface 14 of the pressure roller 48 at the center portion C, and peeled off the release paper R. Affixed to the surface S of the inclined frame portion F1 gradually from the region in the longitudinal direction. At this time, the pressure roller 48 is elastically deformed following the shape of the surface S of the inclined frame portion F1, so that the central portion C of the adhesive tape T is placed between the ridge and the adhesive layer A and the object surface S. It acts to stick to the object surface S while efficiently removing air intake into the object. The pressing force applied to the adhesive tape T from the pressure roller 48 can be intentionally applied by the operator during the moving operation of the main body 12, but is stabilized by the elastic biasing force of the elastic member 36 acting on the second member 26. Secured.

圧着ローラ４８により中央部分Ｃが物体表面Ｓに貼付された粘着テープＴは、貼付装置１０の連続移動に伴い、本体１２と物体Ｏとの間で装置移動方向Ｄ´とは逆の送り方向Ｄへ連続的に送られる。送り経路Ｐに沿った粘着テープＴのこのような送り動作に伴い、剥離端を排出板４６上に載せていた離型紙Ｒは、剥離棒４４の作用により自動的かつ漸進的に粘着テープＴから剥離され、排出板４６の逃がし面４６ａに沿って装置外部に排出される。   The pressure-sensitive adhesive tape T having the central portion C stuck to the object surface S by the pressure roller 48 is fed in a direction D which is opposite to the device moving direction D ′ between the main body 12 and the object O as the sticking device 10 continuously moves. Sent continuously to. With such a feeding operation of the adhesive tape T along the feeding path P, the release paper R having the peeling end placed on the discharge plate 46 is automatically and gradually removed from the adhesive tape T by the action of the peeling bar 44. It is peeled off and discharged to the outside of the apparatus along the relief surface 46a of the discharge plate 46.

貼付装置１０の連続移動に伴い、圧着ローラ４８により中央部分Ｃが物体表面Ｓに貼付された粘着テープＴは、両縁部分Ｍを浮かせた状態で、送り方向Ｄに見て下流側の一対の縁曲げローラ５２に対向する位置に到達する（図９（ａ））。そこで操作者は、縁曲げローラ５２に関連して設けた一対のハンドル６２を握持操作して、両縁曲げローラ５２を支持する軸５４を、本体第１部材２２の長穴５６に沿って適当な位置及び姿勢に変位させるとともに、各縁曲げローラ５２を、軸５４上で付勢部材５８の付勢力に抗して適当な軸線方向位置に変位させ、それにより両縁曲げローラ５２の第２当接面１８を、粘着テープＴを介して、傾斜枠部分Ｆ１の両縁Ｅに適度な押圧力下で押し付ける。この状態で、貼付装置１０を傾斜枠部分Ｆ１に沿って継続して移動させると、粘着テープＴの各縁部分Ｍが、各縁曲げローラ５２の第２当接面１８によって、長手方向へ漸進的に傾斜枠部分Ｆ１の各縁Ｅに沿って折り曲げられる（図９（ｂ））。   With the continuous movement of the sticking device 10, the adhesive tape T having the central portion C stuck to the object surface S by the pressure roller 48 is a pair of downstream sides as viewed in the feeding direction D with both edge portions M floating. It reaches a position facing the edge bending roller 52 (FIG. 9A). Therefore, the operator grips a pair of handles 62 provided in association with the edge bending roller 52, and moves the shaft 54 that supports both edge bending rollers 52 along the elongated hole 56 of the main body first member 22. Each edge bending roller 52 is displaced to an appropriate axial position against the urging force of the urging member 58 on the shaft 54, thereby shifting the edge bending rollers 52 to the appropriate positions and postures. 2 The abutting surface 18 is pressed against the both edges E of the inclined frame portion F1 through the adhesive tape T under an appropriate pressing force. When the sticking device 10 is continuously moved along the inclined frame portion F1 in this state, each edge portion M of the adhesive tape T is gradually advanced in the longitudinal direction by the second contact surface 18 of each edge bending roller 52. Thus, it is bent along each edge E of the inclined frame portion F1 (FIG. 9B).

上記した粘着テープＴの縁曲げ段階で、操作者は、個々の縁曲げローラ５２の第２当接面１８から粘着テープＴの対応の縁部分Ｍに加わる押圧力を、一対のハンドル６２を操作することにより適当に制御することができる。このような適当に制御された押圧力と、縁曲げローラ５２が有する第２当接面１８の形状及び硬度とが相関的に作用して、粘着テープＴの両縁部分Ｍが、その皺や粘着剤層Ａと傾斜枠部分Ｆ１の縁Ｅとの間への空気取込みを効率良く排除しながら、縁Ｅに沿って自動的に折り曲げられる。その結果、粘着剤層Ａが傾斜枠部分Ｆ１の縁Ｅに対して発揮する粘着力により、粘着テープＴの両縁部分Ｍは、中央部分Ｃに対し約９０度の角度を成す折り曲げ形態に保持される。   In the edge bending stage of the adhesive tape T described above, the operator operates the pair of handles 62 with the pressing force applied to the corresponding edge portion M of the adhesive tape T from the second contact surface 18 of each edge bending roller 52. By doing so, it can be controlled appropriately. Such an appropriately controlled pressing force and the shape and hardness of the second abutting surface 18 of the edge bending roller 52 act in a correlated manner, so that both edge portions M of the adhesive tape T have their wrinkles and It is automatically bent along the edge E while efficiently eliminating air intake between the adhesive layer A and the edge E of the inclined frame portion F1. As a result, due to the adhesive force that the adhesive layer A exerts on the edge E of the inclined frame portion F1, both edge portions M of the adhesive tape T are held in a bent form that forms an angle of about 90 degrees with respect to the central portion C. Is done.

このようにして、粘着テープＴの斜辺領域Ｔ１の全体を、貼付装置１０による圧着段階及び縁曲げ段階を経て、物体Ｏの傾斜枠部分Ｆ１に貼付した後、仕上げ作業として、粘着テープＴの斜辺領域Ｔ１の両縁部分Ｍを、手作業により表面Ｓの反対側の裏面Ｓ´（図９（ｂ））に完全に貼り付ける。このような仕上げ作業は、既に約９０度の適正な縁曲げ形態にある粘着テープＴの両縁部分Ｍに対し、熟練を要することなく迅速かつ安全に実施することができる。このようにして物体Ｏの傾斜枠部分Ｆ１に貼付された粘着テープＴの斜辺領域Ｔ１は、その両縁部分Ｍで傾斜枠部分Ｆ１の両縁Ｅを包み込むように配置されており、粘着テープＴの端縁剥離や粘着剤層Ａと物体表面Ｓとの間への水分浸入を防止し得る望ましい貼付形態となる。   In this way, the entire hypotenuse region T1 of the adhesive tape T is pasted to the inclined frame portion F1 of the object O through the crimping step and the edge bending step by the pasting device 10, and then the hypotenuse of the adhesive tape T as a finishing operation. Both edge portions M of the region T1 are completely pasted to the back surface S ′ (FIG. 9B) opposite to the front surface S by hand. Such a finishing operation can be carried out quickly and safely on both edge portions M of the adhesive tape T already in an appropriate edge bending form of about 90 degrees without requiring skill. In this way, the hypotenuse region T1 of the adhesive tape T affixed to the inclined frame portion F1 of the object O is disposed so as to wrap around both edges E of the inclined frame portion F1 with both edge portions M. This is a desirable pasting form that can prevent edge peeling and moisture intrusion between the pressure-sensitive adhesive layer A and the object surface S.

上記したように、貼付装置１０においては、縁曲げ部材２０を構成する一対の縁曲げローラ５２の軸５４を、本体１２に設けた長穴５６が許容する範囲で自在に変位できるようにしたから、物体Ｏの表面Ｓの湾曲や捩れ等により物体Ｏの各縁Ｅが多様な曲線状に延びている場合にも、圧着ローラ４８の第１当接面１４と物体表面Ｓとの当接形態に影響されることなく、各縁曲げローラ５２の第２当接面１８を物体Ｏの対応の縁Ｅに適正に追従させることができる。したがって、そのような湾曲又は捩れ形態を有する物体Ｏに対し、その両縁Ｅに粘着テープＴの両縁部分Ｍを正確に沿わせて折り曲げることができる。   As described above, in the sticking device 10, the shafts 54 of the pair of edge bending rollers 52 constituting the edge bending member 20 can be freely displaced within the range allowed by the long hole 56 provided in the main body 12. Even when each edge E of the object O extends in various curved shapes due to the curvature or twist of the surface S of the object O, the contact form between the first contact surface 14 of the pressure roller 48 and the object surface S The second contact surface 18 of each edge bending roller 52 can appropriately follow the corresponding edge E of the object O without being affected by the above. Therefore, it is possible to bend the object O having such a curved or twisted shape so that both edge portions M of the adhesive tape T are accurately along the both edges E.

また、貼付装置１０では、各縁曲げローラ５２を、軸５４上で軸線方向移動可能に設置したから、貼付装置１０を物体Ｏの表面Ｓに沿って移動させる間に物体Ｏの幅寸法が変化する場合にも、個々の縁曲げローラ５２の第２当接面１８を物体Ｏの縁Ｅに正確に追従させることができる。したがって、図４に示す適用例では、自動車のドアフレームからなる物体Ｏにおいて、徐々に変化する幅を有する縦枠部分Ｆ２に、ドアフレームに対応する形状に成形された粘着テープＴの、同様に変化する幅を有する縦辺領域Ｔ２を貼付する際にも、貼付装置１０を使用することができる。なお、縁曲げローラ５２に関連して設けた付勢部材５８は、各縁曲げローラ５２の軸線方向変位操作を容易にする。   In the pasting device 10, each edge bending roller 52 is installed on the shaft 54 so as to be movable in the axial direction, so that the width dimension of the object O changes while the pasting device 10 is moved along the surface S of the object O. Also in this case, the second contact surface 18 of each edge bending roller 52 can accurately follow the edge E of the object O. Therefore, in the application example shown in FIG. 4, in the object O composed of the door frame of the automobile, the adhesive tape T formed into a shape corresponding to the door frame is similarly formed on the vertical frame portion F2 having a gradually changing width. The sticking device 10 can also be used when sticking the vertical side region T2 having a varying width. The urging member 58 provided in association with the edge bending roller 52 facilitates the axial displacement operation of each edge bending roller 52.

さらに、貼付装置１０では、縁曲げローラ５２を支持する軸５４の両端の延長部６０に、各縁曲げローラ５２を本体１２に対して変位させるためのハンドル６２を設けたから、操作者は、ハンドル６２を握持して個々の縁曲げローラ５２の位置及び姿勢を制御しながら、貼付装置１０の全体を物体Ｏに沿って移動させることができる。したがって、粘着テープＴの圧着段階及び縁曲げ段階を、きわめて容易かつ正確に遂行することができる。   Further, in the sticking device 10, the handle 62 for displacing each edge bending roller 52 with respect to the main body 12 is provided at the extension portions 60 at both ends of the shaft 54 that supports the edge bending roller 52. The entire applicator 10 can be moved along the object O while gripping 62 and controlling the position and posture of the individual edge bending rollers 52. Therefore, the pressure bonding step and the edge bending step of the adhesive tape T can be performed very easily and accurately.

以上の説明から明らかなように、本発明に係る貼付装置によれば、１回の貼付作業で、粘着テープの縁部分を物体の縁に沿って自動的に折り曲げながら粘着テープを物体表面に貼付できるので、テープ貼付作業に熟練を必要としなくなり、しかも貼付作業の安全性を著しく向上させるとともに、作業時間を著しく短縮することができる。実際のところ、図４に示す適用例において、従来の圧着専用の貼付治具を用いて粘着テープＴの中央部分Ｃをドアフレームの傾斜枠部分Ｆ１の表面Ｓに貼付した後に手作業で粘着テープＴの両縁部分Ｍを傾斜枠部分Ｆ１の両縁Ｅに沿って折り曲げる作業に比べて、貼付装置１０を用いて前述した粘着テープＴの縁曲げ貼付作業を実施したところ、作業時間を約７０％まで短縮することができた。   As is apparent from the above description, according to the sticking device of the present invention, the adhesive tape is stuck to the object surface while the edge portion of the adhesive tape is automatically folded along the edge of the object in one sticking operation. Therefore, skill is not required for the tape application work, and the safety of the application work can be remarkably improved and the operation time can be shortened remarkably. Actually, in the application example shown in FIG. 4, the adhesive tape is manually applied after the central portion C of the adhesive tape T is applied to the surface S of the inclined frame portion F1 of the door frame using a conventional application tool dedicated for crimping. Compared with the operation of bending both edge portions M of T along both edges E of the inclined frame portion F1, when the edge bending and sticking operation of the adhesive tape T described above was performed using the attaching device 10, the work time was reduced to about 70. %.
