Description

本発明は塗膜転写具に関する。さらに詳細に言えば、巻取りリールにより巻き取られるテープが弛むのを防止することのできるテープ巻取り機構に関する。   The present invention relates to a coating film transfer tool. More specifically, the present invention relates to a tape take-up mechanism that can prevent a tape taken up by a take-up reel from loosening.

従来から修正用の塗膜或いは糊などの塗膜を有するテープを備えた塗膜転写具が使用されている。この塗膜転写具では、テープを供給する側の供給リールと、テープを巻き取る側の巻取りリールとを備え、それぞれに対応して設けられる駆動ギヤと被動ギヤとを噛合わせる。そして、転写ヘッドを紙面などに押付けて転写具を移動させ、これによりテープを供給リールから繰出すと共に供給リールを回転させ、駆動ギヤと被動ギヤの噛合いにより供給リールに巻取りリールを連動させてテープの使用済み部分を巻き取るようになっている。   Conventionally, a coating film transfer tool having a tape having a coating film for correction or a coating film such as glue has been used. The coating film transfer tool includes a supply reel on the tape supply side and a take-up reel on the tape winding side, and meshes a driving gear and a driven gear provided corresponding to each. Then, the transfer head is pressed against the paper surface to move the transfer tool, whereby the tape is fed from the supply reel and the supply reel is rotated, and the take-up reel is interlocked with the supply reel by meshing of the drive gear and the driven gear. And take up the used part of the tape.

ところで、従来の転写具においては、巻取りリールによるテープの巻取りが完全に行なわれず、テープに弛みが生じる場合がある。例えば、噛合う歯車のバックラッシュに起因する弛みの発生がある。通常供給リール側にはラチェットを利用した逆転防止機構が設けられているが、転写具の操作の具合によっては、ラチェットの1ピッチを越えない範囲で逆戻りする場合がある。そして、巻取りリールは前述のとおりギヤの噛合いにより回転するようになっており、ギヤの噛合いにはバックラッシュがあるため、テープに弛みが生じることがしばしばある。テープが弛むと未使用の塗膜先端が転写ヘッド先端の押圧部からずれてしまい、次に使用した場合に最初の部分に転写されず、塗り直しをするする必要が生じたりする。   By the way, in the conventional transfer tool, the winding of the tape by the winding reel is not completely performed, and the tape may be loosened. For example, there is the occurrence of slack due to backlash of meshing gears. Normally, a reverse rotation prevention mechanism using a ratchet is provided on the supply reel side. However, depending on how the transfer tool is operated, there is a case where the reverse rotation is performed within a range not exceeding one pitch of the ratchet. As described above, the take-up reel is rotated by the meshing of the gear. Since the meshing of the winding has backlash, the tape is often loosened. When the tape is loosened, the unused coating film tip is displaced from the pressing portion at the tip of the transfer head, and when it is used next time, it is not transferred to the first part, and it may be necessary to repaint.

特許第2995659号特許公報Japanese Patent No. 29956659

本願発明は上記従来の問題点に鑑みなされたものであり、巻取りリールにより巻き取られるテープに弛みが生じるのを防止できる、テープ巻取り機構を提供することをその課題とする。   The present invention has been made in view of the above-described conventional problems, and an object thereof is to provide a tape take-up mechanism that can prevent the tape taken up by the take-up reel from being slackened.

上記課題を解決するために、本願発明のテープ巻取り機構においては、巻取りリールと巻取りリールに対応して設けられる被動ギヤとを同軸上に相対回転可能に設け、巻取りリールと被動ギヤとの間に、巻取りリールを被動ギヤに対して、テープを巻き取る方向へ回転させる付勢力を付与する付勢手段を設けた。   In order to solve the above problems, in the tape winding mechanism of the present invention, the take-up reel and the driven gear provided corresponding to the take-up reel are provided on the same axis so as to be relatively rotatable, and the take-up reel and the driven gear are provided. In between, a biasing means for applying a biasing force to rotate the take-up reel to the driven gear in the direction of winding the tape is provided.

ある実施の形態では、その被動ギヤは上方へ延びる中心軸を備え、巻取りリールは筒状に形成されて被動ギヤの上にその中心軸を囲繞した状態で載置される。そして、付勢手段は、中心軸の外周面と巻取りリールの内周面との間の画成される円環状空所に配置されている。   In one embodiment, the driven gear includes a central shaft extending upward, and the take-up reel is formed in a cylindrical shape and is placed on the driven gear in a state surrounding the central shaft. The urging means is disposed in an annular space defined between the outer peripheral surface of the central shaft and the inner peripheral surface of the take-up reel.

さらに他の実施の形態では、中心軸の外周面上及びリールの内周面上に、径方向に突出する係止部が形成され、付勢手段はこの中心軸とリールのそれぞれの係止部に両端を取付けられる圧縮バネで構成される。   In still another embodiment, locking portions projecting in the radial direction are formed on the outer peripheral surface of the central shaft and the inner peripheral surface of the reel, and the urging means is the respective locking portions of the central shaft and the reel. It consists of a compression spring that can be attached at both ends.

上記の通り、本願発明では、巻取りリールと巻取りリールに対応して設けられる被動ギヤとを同軸上に相対回転可能に設け、巻取りリールと被動ギヤとの間に、巻取りリールを被動ギヤに対して、テープを巻き取る方向へ回転させる付勢力を付与する付勢手段を設けたので、テープに弛みが生じようとすると、巻取りリールが被動ギヤに対してテープの巻取り方向へ回動し、テープの弛みを吸収することができる。   As described above, in the present invention, the take-up reel and the driven gear provided corresponding to the take-up reel are provided coaxially and relatively rotatable, and the take-up reel is driven between the take-up reel and the driven gear. Since the biasing means for applying a biasing force to rotate the tape in the direction of winding the tape is provided, if the tape is slack, the winding reel moves in the tape winding direction with respect to the driven gear. It can rotate and absorb the slack of the tape.

以下、図面を参照しながら本願発明の実施の形態を説明する。図1は本願発明の実施の形態に係るテープ巻取り機構を使用した塗膜転写具1を示す平面断面図であり、図2はテープ巻取り機構の平面図、図3は図2のA−A線断面図である。なお、図1においては主要な部材のみを示した。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a plan sectional view showing a coating film transfer tool 1 using a tape winding mechanism according to an embodiment of the present invention, FIG. 2 is a plan view of the tape winding mechanism, and FIG. It is A sectional view. In FIG. 1, only main members are shown.

図1において符号3はケースであり、符号6はケース3内に回転可能に支持されたテープ4の供給リールである。供給リール6は駆動ギヤ7と同軸上に設けられており、両者は通常は一体に回転するが、負荷が掛かると互いにスリップするようになっている。供給リール6と駆動ギヤ7とでテープの供給機構5が構成される。一方テープの巻取り機構11は、巻取りリール13と、巻取りリール13と同軸に配置され、駆動ギヤ7に噛合う被動ギヤ23とを備えている。符号8はと取付け部9においてケースに取付けられた公知の転写ヘッドである。以下、図2及び3を主に参照して、巻取り機構11について詳述する。   In FIG. 1, reference numeral 3 denotes a case, and reference numeral 6 denotes a supply reel of the tape 4 that is rotatably supported in the case 3. The supply reel 6 is provided coaxially with the drive gear 7 and both normally rotate together, but slip each other when a load is applied. The supply reel 6 and the drive gear 7 constitute a tape supply mechanism 5. On the other hand, the tape winding mechanism 11 includes a winding reel 13 and a driven gear 23 that is arranged coaxially with the winding reel 13 and meshes with the drive gear 7. Reference numeral 8 denotes a known transfer head attached to the case at the attachment portion 9. Hereinafter, the winding mechanism 11 will be described in detail with reference mainly to FIGS.

被動ギヤ23は、円板状の形をした本体部25を備え、その下面側に円環状の形成されたギヤ部27が形成され、その外周側には歯型29が形成されている。一方本体部25の上面側には、本体部25まで貫通して中空になっている中空軸31が形成され、この中空軸31に前述のケース3に形成された支軸が嵌ることにより、被動ギヤ23は回転するようになっている。本体部25の上面側にはさらに、中空軸31の外側に、同心状に丈の低い円形ガイド33が形成されている。   The driven gear 23 includes a disk-shaped main body 25, an annular gear portion 27 is formed on the lower surface side, and a tooth die 29 is formed on the outer peripheral side thereof. On the other hand, on the upper surface side of the main body 25, a hollow shaft 31 that penetrates to the main body 25 and is hollow is formed, and the support shaft formed in the case 3 is fitted to the hollow shaft 31, thereby The gear 23 is configured to rotate. On the upper surface side of the main body 25, a concentric circular guide 33 having a low length is formed outside the hollow shaft 31.

巻取りリール13は略円筒形をしており、その下端部が被動ギヤ23の円形ガイド33に図示の通り嵌った状態で、被動ギヤ23の本体部25の上に載っている。なお、図示を省略するが、円形ガイド33と巻取りリール13には、互いに嵌る円周方向に延びる溝と突状を設けるなどして、巻取りリール13が円形ガイド33から外れないようにしておくのが望ましい。   The take-up reel 13 has a substantially cylindrical shape, and is placed on the main body 25 of the driven gear 23 with its lower end fitted into the circular guide 33 of the driven gear 23 as shown in the figure. Although not shown in the drawings, the circular guide 33 and the take-up reel 13 are provided with grooves and protrusions extending in the circumferential direction so as to be fitted to each other so that the take-up reel 13 does not come off from the circular guide 33. It is desirable to leave.

巻取りリール13の内周側には、円周方向所定の間隔で、本実施の形態では180度間隔で3つの、薄板状の内方リブ15が、所定の幅だけ径方向内方へ突出した状態で、上端から下方所定の位置まで延びて形成されている。一方被動ギヤ23の中空軸31の外周側には、巻取りリール13の内方リブ15に対応して、円周方向180度間隔で3つの、薄板状の外方リブ35が、所定の幅だけ径方向外方へ突出した状態で、上端から下方所定の位置まで延びて形成されている。   On the inner peripheral side of the take-up reel 13, three thin plate-like inner ribs 15 protrude inward in the radial direction by a predetermined width at predetermined intervals in the circumferential direction, and at intervals of 180 degrees in this embodiment. In this state, it extends from the upper end to a predetermined position. On the other hand, on the outer peripheral side of the hollow shaft 31 of the driven gear 23, three thin plate-like outer ribs 35 corresponding to the inner ribs 15 of the take-up reel 13 are spaced at a predetermined width by 180 degrees in the circumferential direction. It is formed to extend downward from the upper end to a predetermined position in a state protruding only outward in the radial direction.

そして、それぞれ対応する内方リブ15と外方リブ35との間に、付勢手段としての圧縮バネ41が配設されている。圧縮バネ41はその両端をそれぞれ、内方リブ15と外方リブ35とに、それらに形成された例えばスリット或いは小孔を利用して取付けることができる。圧縮バネ41は、1の外方リブ35と、その外方リブ35に対して反時計方向前方に位置する内方リブ15との間に配設され、従って、巻取りリール13を被動ギヤ23に対して反時計方向、すなわち、テープを巻き取る方向に回転するよう付勢している。 A compression spring 41 is provided as a biasing means between the corresponding inner rib 15 and outer rib 35. Both ends of the compression spring 41 can be attached to the inner rib 15 and the outer rib 35 using, for example, slits or small holes formed in them. The compression spring 41 is disposed between one outer rib 35 and the inner rib 15 positioned forward in the counterclockwise direction with respect to the outer rib 35, and accordingly, the take-up reel 13 is moved to the driven gear 23. Is urged to rotate counterclockwise, that is, in the direction of winding the tape.

上記のように構成されたテープの巻取り機構11においては、通常の状態ではテープが張り、巻取りリール13を被動ギヤ23に対して時計方向へ回動させるように作用し、圧縮バネ41が圧縮された状態となっている。従って、転写具の使用時においてバックラッシュにより被動ギヤが僅かに巻取り方向と反対の方向に回動してテープに弛みが生じようとすると、巻取りリール13は圧縮バネ41の作用により被動ギヤ23に対して反時計方向へ回動し、テープ4の弛みを吸収することとなる。   In the tape take-up mechanism 11 configured as described above, the tape is stretched in a normal state, acts to rotate the take-up reel 13 clockwise with respect to the driven gear 23, and the compression spring 41 It is in a compressed state. Therefore, when the transfer tool is used, if the driven gear rotates slightly in the direction opposite to the winding direction due to backlash and the tape is slackened, the winding reel 13 is driven by the action of the compression spring 41. Rotate counterclockwise with respect to 23 and absorb the slack of the tape 4.

本願発明の構成は上記に説明した実施の形態に限定されるものではない。例えば上記の実施の形態では圧縮バネを使用したが、例えばU字或いはV字に折り曲げた板バネなどの使用も可能である。   The configuration of the present invention is not limited to the embodiment described above. For example, although the compression spring is used in the above-described embodiment, for example, a leaf spring bent into a U-shape or a V-shape can be used.
