Description
本発明は、成型ドラムに巻き回したタイヤ構成部材の巻き始端と巻き終端のそれぞれの端面を、相互に突き合わせて接合する、タイヤ構成部材のジョイント装置に関するものである。 [Technical Field] The present invention relates to a joint device for a tire constituent member in which respective end surfaces of a winding start end and a winding end end of a tire constituent member wound around a molding drum are butted against each other.
タイヤを成型するに当っては、タイヤ構成部材、例えば、複数本の引き揃えコードを未加硫ゴムで被覆してなるシート状のカーカスプライ素材を、成型ドラムの周面に巻き回し、その巻き始端と巻き終端を接合して、円筒状のカーカスバンドとすることが行われている。この場合の両端部の代表的な接合方法としては、巻き始端の上に巻き終端を重ね合わせて接合する方法と、両端部の端面を突き合わせ接合する方法とが知られている。ところで、接合部に段差ができず高いユニフォミティが得られる点では、端面を突き合わせ接合する方法が有利であり、このような接合に用いられる装置としては、例えば特許文献１に記載されているような、一対の截頭円錐状のローラの周面を突き合わせ接合のジッパーとして用いたジョイント装置が知られている。 When molding a tire, a tire-shaped member, for example, a sheet-like carcass ply material formed by coating a plurality of alignment cords with unvulcanized rubber, is wound around the peripheral surface of a molding drum, and the winding is performed. It has been practiced to join a start end and a winding end to form a cylindrical carcass band. As typical joining methods at both ends in this case, there are known a method in which the winding end is overlapped on the winding start end and joining, and a method in which the end surfaces of both ends are butted and joined. By the way, in the point which cannot make a level | step difference in a junction part and a high uniformity is obtained, the method of butt-joining an end surface is advantageous, As an apparatus used for such joining, for example, it is described in patent document 1 A joint device is known in which the peripheral surfaces of a pair of frustoconical rollers are used as a butt zipper.
ところで、上記のようにタイヤ構成部材の端面を突き合わせて接合するには、タイヤ構成部材の巻き始端と巻き終端とを、互いに引き寄せることが必要であるが、ジョイント装置の前進方向側でタイヤ構成部材の端部間隔が次第に大きくなる場合は、両端部を十分に引き寄せることができず、突き合わせ接合を最後まで確実に行うことができない懸念があった。 By the way, in order to abut the end surfaces of the tire constituent members as described above, it is necessary to draw the winding start end and the winding end of the tire constituent members toward each other. In the case where the distance between the end portions gradually increases, there is a concern that the both end portions cannot be sufficiently drawn together and the butt joining cannot be reliably performed to the end.
本発明の課題は、成型ドラムに巻き回したタイヤ構成部材の巻き始端と巻き終端を、十分に引き寄せることが可能であり、タイヤ構成部材の両端面を確実に突き合わせ接合できるジョイント装置を提供することにある。 An object of the present invention is to provide a joint device that can sufficiently draw the winding start end and winding end of a tire constituent member wound around a molding drum, and can reliably butt and join both end faces of the tire constituent member. It is in.
本発明は、成型ドラムの周面に巻き回したタイヤ構成部材の巻き始端と巻き終端のそれぞれの端面を、成型ドラムの軸線に合わせて相互に突き合わせて接合するタイヤ構成部材のジョイント装置であって、成型ドラムの軸線方向に前進変位する本体部と、該本体部に回動可能に取り付けられて、巻き始端と巻き終端とに跨って位置し、本体部の前進変位に当って、前記両端面を突き合わせ接合するジッパーと、本体部の、前記ジッパーよりも前方側に配置され、小径端を互いに対向させた姿勢で配設されて、前記巻き始端と巻き終端のそれぞれに接触し、共通の軸線上で回動する一対以上の截頭円錐状の引き寄せローラと、を備えてなり、
前記引き寄せローラの周面と前記巻き始端及び巻き終端のそれぞれとを、該引き寄せローラの母線上で小径端から大径端に至るまで接触させてなるものである。
The present invention is a joint device for a tire constituent member that joins the end surfaces of the winding start end and the winding end end of the tire constituent member wound around the peripheral surface of the molding drum by matching each other along the axis of the molding drum. A main body portion that is displaced forward in the axial direction of the molding drum, and is rotatably attached to the main body portion, and is positioned across the winding start end and the winding end. A zipper that butt-joins the main body, and a main body portion that is disposed on the front side of the zipper and that has a small-diameter end facing each other, and is in contact with each of the winding start end and winding end, and a common shaft Ri Na equipped with a pair or more frustoconical drawn roller which rotates on a line,
And each of said drawn the winding start end and the winding terminal end and the peripheral surface of the roller, it is shall such be contacted from the small diameter end on the generatrix of the drawn roller to large diameter end.
このような装置において好ましくは、本体部を、支持部材により、垂直面内で揺動可能に支持する。 In such an apparatus, the main body is preferably supported by a support member so as to be swingable in a vertical plane.
また好ましくは、本体部に、成型ドラムの軸線方向に前進変位させる駆動手段を設ける。 Preferably, the main body is provided with driving means for moving forward in the axial direction of the molding drum.
そしてまた好ましくは、上述した何れかのジョイント装置をシングル成型機に付設する。 Preferably, any of the joint devices described above is attached to the single molding machine.
このジョイント装置では、成型ドラムの軸線方向に前進変位する本体部に、タイヤ構成部材を突き合わせ接合するジッパーを配設するとともに、このジッパーよりも前方側に、小径端を互いに対向させた姿勢で、巻き始端と巻き終端のそれぞれに接触させ、共通の軸線上で回動する一対以上の截頭円錐状の引き寄せローラを設けたので、これらの引き寄せローラによって、タイヤ構成部材の両端部を十分に引き寄せることが可能となり、それらのローラが通過した部分にジッパーが到達した際には、タイヤ構成部材の両端面が接近或いは当接されているので、それらの両端面の突き合わせ接合が常に確実に行われる。 In this joint device, a zipper for abutting and joining the tire constituent members is disposed on the main body portion that moves forward in the axial direction of the molding drum, and the small diameter ends are opposed to each other on the front side of the zipper, Since one or more frusto-conical pulling rollers that are brought into contact with the winding start end and the winding end and rotate on a common axis are provided, both end portions of the tire constituent member are sufficiently pulled by these pulling rollers. When the zipper reaches the part through which the rollers have passed, the both end faces of the tire constituent members are approaching or abutting, so that the butt joining of the both end faces is always performed reliably. .
この発明のジョイント装置で、本体部を、支持部材により垂直面内で揺動可能に支持したときは、例えばカーカスプライ素材にサイドウォール素材を貼り付けたものをタイヤ構成部材として、これを均一直径の成型ドラム上で、円筒状に突き合わせ接合する場合のように、接合部分に傾斜域が発生することがあっても、引き寄せローラがこの傾斜部を乗り越え始めると本体部が揺動して追従し、ジッパーを、この傾斜部に直角に押し付けることができるので、種々の形状のタイヤ構成部材を、軸線方向の全長に亘って所期した通りに均一に接合させることができる。 In the joint device according to the present invention, when the main body is supported by the support member so as to be swingable in a vertical plane, for example, a carcass ply material pasted with a sidewall material is used as a tire constituent member, and this is a uniform diameter. Even if an inclined area may occur in the joining portion, as in the case of butt-joining in a cylindrical shape on the molding drum, the main body swings and follows when the pulling roller starts to get over the inclined portion. Since the zipper can be pressed at right angles to the inclined portion, tire constituent members of various shapes can be uniformly joined as expected over the entire length in the axial direction.
また本体部を、成型ドラムの軸線方向に前進変位させる駆動手段を設けた場合には、タイヤ構成部材を自動で接合できるので、生産性の向上と作業工数の低減を図ることが可能となる。 In addition, when the driving means for moving the main body portion forwardly in the axial direction of the molding drum is provided, the tire constituent members can be joined automatically, so that it is possible to improve productivity and reduce the number of work steps.
さらに、このジョイント装置を、シングル成型機に付設した場合は、インナーライナーの貼り付けから生タイヤが形成されるまで、一つの成型ドラム上で作業を行うことができるので、さらに効率的に、生産性の向上と作業の軽労化を図ることができ、併せて半製品を他の成型ドラムに乗せ代える場合に比し、半製品の意図しない変形等のおそれを取り除くことができる。 Furthermore, when this joint device is attached to a single molding machine, work can be performed on a single molding drum from the application of the inner liner to the formation of the raw tire, making production more efficient. As a result, the possibility of unintentional deformation or the like of the semi-finished product can be eliminated as compared with the case where the semi-finished product is placed on another molding drum.
以下、図面を参照して、本発明をより具体的に説明する。なお各部材の形状、特に各ローラの傾斜角度は誇張して示している。 Hereinafter, the present invention will be described more specifically with reference to the drawings. In addition, the shape of each member, especially the inclination angle of each roller is exaggerated.
図１に示すところにおいて、１は、成型ドラムの一部である。成型ドラム１は円筒状であり、軸線１ａを中心に回転駆動される。 In FIG. 1, 1 is a part of the molding drum. The molding drum 1 has a cylindrical shape and is driven to rotate about the axis 1a.
図１において、２は、成型ドラム１の周面に巻き回されたタイヤ構成部材である。タイヤ構成部材２は、例えば成型ドラム１の軸線方向に延在する複数本の引き揃えコードを、未加硫ゴムで被覆してなる、シート状のカーカスプライ素材であり、成型ドラム１の周面に巻き回して、その巻き始端と巻き終端を接合することで、円筒状のカーカスバンドが形成される。本発明においては、シート状のタイヤ構成部材２の長さは、成型ドラム１の周長の略１周分としている。 In FIG. 1, reference numeral 2 denotes a tire constituent member wound around the peripheral surface of the molding drum 1. The tire component 2 is a sheet-like carcass ply material formed by coating a plurality of alignment cords extending in the axial direction of the molding drum 1 with unvulcanized rubber, for example. And a cylindrical carcass band is formed by joining the winding start end and the winding end. In the present invention, the length of the sheet-like tire constituent member 2 is approximately one circumference of the circumference of the molding drum 1.
３は、ジョイント装置の本体部である。本体部３は、図示は省略するが、例えばリニアガイドのような直線状の軌道に、後述する支持部材によって取り付けられており、成型ドラム１の軸線１ａの方向に前進変位できるようになっている。本体部３の前進変位は、例えばジョイント装置の何れかの部位に、ハンドル等を設けて手動で行われるようにしてもよいが、例えば、ねじ機構とモータとを組み合わせて、自動で前進変位できるようにした駆動手段を設けた場合には、生産性の向上と作業工数の低減を図ることができる。また、本体部３は、図示しないシリンダー等の昇降手段によって、成型ドラム１の半径方向に昇降変位可能とされており、突き合わせ接合時には、成型ドラム１に向けて下降変位させて、ジョイント装置をタイヤ構成部材２に当接させることが可能であり、タイヤ構成部材２を巻き回す時には、成型ドラム１から上昇変位させることができるので、作業性を損なうことがない。 Reference numeral 3 denotes a main body of the joint device. Although not shown, the main body 3 is attached to a linear track such as a linear guide by a support member described later, and can be displaced forward in the direction of the axis 1 a of the molding drum 1. . The forward displacement of the main body 3 may be manually performed by providing a handle or the like at any part of the joint device, for example. However, the forward displacement can be automatically performed by combining a screw mechanism and a motor, for example. When the drive means is provided, productivity can be improved and man-hours can be reduced. The main body 3 can be moved up and down in the radial direction of the molding drum 1 by lifting means such as a cylinder (not shown). At the time of butt joining, the main body 3 is displaced downward toward the molding drum 1 so that the joint device is a tire. It can be brought into contact with the component member 2, and when the tire component member 2 is wound, it can be displaced upward from the molding drum 1, so that workability is not impaired.
４は、タイヤ構成部材２の巻き始端と巻き終端の端面を、突き合わせ接合するジッパーを示す。一対の截頭円錐状のローラからなるこのジッパー４は、本体部３の中心軸線に対して対照に回動可能に取り付けられて、巻き始端と巻き終端との両者に跨って配設される。図示のジッパー４は、一対の截頭円錐状のローラを、小径端が互いに対向する姿勢で、かつこれらを共通の軸線上に配設して、本体部３の前進変位によって連れまわり可能に取り付けたものである。ここで、一対の截頭円錐状のローラは、それぞれが個別に回動するものでもよいが、タイヤ構成部材２の両端部を均一に接合する為には、相互に連結して、又は一体化して、回動させることが好ましい。なおジッパー４は、図示の構成に限られず、例えば一対の円筒状のローラを、それぞれの軸線を進行方向に対して傾斜させた姿勢で、巻き始端と巻き終端とのそれぞれに接触する位置に回動自在に取り付けたものでもよいし、従来技術で述べたように、截頭円錐状のローラの周面をこれらの端部に接触させるようにして、傾斜した軸線上で回転するものでもよい。 4 shows the zipper which butt-joins the end surface of the winding start end and winding end of the tire structural member 2. The zipper 4 composed of a pair of frustoconical rollers is rotatably attached to the central axis of the main body 3 in a contrasting manner, and is disposed across both the winding start end and winding end. The illustrated zipper 4 has a pair of frustoconical rollers attached so that the small-diameter ends thereof face each other and are disposed on a common axis so that they can be rotated by a forward displacement of the main body 3. It is a thing. Here, each of the pair of frustoconical rollers may be individually rotated. However, in order to join both end portions of the tire constituent member 2 uniformly, they are mutually connected or integrated. And preferably rotating. The zipper 4 is not limited to the configuration shown in the figure. For example, a pair of cylindrical rollers are rotated to positions where the respective axes are in contact with the winding start end and the winding end in a posture in which each axis is inclined with respect to the traveling direction. It may be mounted movably, or as described in the prior art, it may be rotated on an inclined axis so that the peripheral surface of the frustoconical roller contacts these ends.
本体部３の前進方向に対して、ジッパー４よりも前方側で本体部３に配置される引き寄せローラ５は、一対以上の截頭円錐状のローラを、小径端を互いに対向させた姿勢で、かつこれらを本体部３の中心軸線に対して対照に、共通の水平軸線上に配設して、そのローラの周面とタイヤ構成部材２とを、ローラの母線上で小径端から大径端に至るまで接触させて、本体部３の前進変位によって連れまわり可能に取り付けたものである。ここで一対の引き寄せローラ５は、それぞれが個別に回動するものでもよいが、タイヤ構成部材２の両端部を均一に引き寄せる為に、相互に連結して、又は一体化して、回動させることが好ましい。また図２に示すように、引き寄せローラ５を、対向する小径端の間隔をおいて配設する場合には、タイヤ構成部材２の端部間隔が大きくなっても、両端部を十分に引き寄せることができるので、より好ましい。 The pulling roller 5 disposed in the main body 3 in front of the zipper 4 with respect to the advancing direction of the main body 3 is a posture in which a pair of or more frustoconical rollers are opposed to each other at the small diameter ends. And these are arranged on a common horizontal axis in contrast to the central axis of the main body part 3, and the peripheral surface of the roller and the tire component 2 are connected from the small-diameter end to the large-diameter end on the roller bus. The main body 3 is attached so as to be able to be rotated by a forward displacement. Here, each of the pair of pulling rollers 5 may rotate individually, but in order to pull both ends of the tire constituent member 2 uniformly, they are connected to each other or integrated and rotated. Is preferred. In addition, as shown in FIG. 2, when the pulling rollers 5 are arranged at intervals of the small diameter ends facing each other, both end portions are sufficiently drawn even when the end portion interval of the tire constituent member 2 is increased. Is more preferable.
またジッパー４、引き寄せローラ５に、例えば、ばね等をからなる付勢手段をそれぞれ個別に設けて、タイヤ構成部材２に、それらの役割に応じた付勢力で押し当てるようにしてもよい。 Further, urging means comprising, for example, a spring or the like may be individually provided on the zipper 4 and the pulling roller 5 so as to be pressed against the tire constituent member 2 with an urging force according to their role.
さらに６は、成型ドラム１の軸線１ａを含む垂直面内で、本体部３を揺動可能に支持する支持部材である。図示の例で支持部材６は、本体部３を挟む一対の板状片からなり、本体部３のボス部に配設された軸３ａを、孔６ａを介して支持している。これにより、接合部分に傾斜域が存在することがあっても、先行する引き寄せローラ５がこの傾斜部を乗り越え始めると、本体部３が揺動して追従するので、ジッパー４は、この傾斜部をその表面と直角に押し付けることができる。 Reference numeral 6 denotes a support member that supports the main body 3 in a swingable manner within a vertical plane including the axis 1 a of the molding drum 1. In the illustrated example, the support member 6 is composed of a pair of plate-like pieces sandwiching the main body 3, and supports the shaft 3 a disposed on the boss portion of the main body 3 through the hole 6 a. As a result, even if there is an inclined region in the joint portion, when the preceding pulling roller 5 starts to get over the inclined portion, the main body portion 3 swings and follows, so that the zipper 4 Can be pressed perpendicularly to the surface.
上記のような構成となるジョイント装置を用いて、タイヤ構成部材２の両端面の突き合わせ接合を行うにあたっては、まず、成型ドラム１にタイヤ構成部材２の巻き回しを行う。この時、ジョイント装置は成型ドラム１から上昇変位している。ここで、成型ドラム１の近傍には投光器が備えられていて、この投光器によって成型ドラム１の周面には、軸線１ａと平行になる投影光が照射されており、この投影光にタイヤ構成部材２の巻き始端と巻き終端のそれぞれの端面を合わせることで、両端面を成型ドラム１の軸線１ａに合わせることができる。 In performing butt joining of both end faces of the tire constituent member 2 using the joint device configured as described above, first, the tire constituent member 2 is wound around the molding drum 1. At this time, the joint device is displaced upward from the molding drum 1. Here, a projector is provided in the vicinity of the molding drum 1, and projection light parallel to the axis 1 a is irradiated to the peripheral surface of the molding drum 1 by the projector, and the tire component is applied to the projection light. By aligning the end surfaces of the winding start end and winding end of 2, both end surfaces can be aligned with the axis 1 a of the molding drum 1.
次に、タイヤ構成部材２の両端面と、ジョイント装置との周方向位置あわせを行う。これには、ジョイント装置（本体部３の中心軸線）が成型ドラム１の半径方向に下降変位する先に、タイヤ構成部材２の両端面が来るように、成型ドラム１を回転させる。成型ドラム１の回転量は、ジョイント装置や成型ドラム１等の駆動を制御する制御装置等（図示せず）にあらかじめ設定されており、毎回決まった位置に回転させることができるので、ジョイント装置とタイヤ構成部材の両端面との相対位置がずれることがない。 Next, the circumferential direction alignment with the both end surfaces of the tire structural member 2 and a joint apparatus is performed. For this purpose, the molding drum 1 is rotated so that both end surfaces of the tire constituent member 2 come before the joint device (the central axis of the main body 3) moves downward in the radial direction of the molding drum 1. The rotation amount of the molding drum 1 is set in advance in a control device (not shown) for controlling the driving of the joint device, the molding drum 1 and the like, and can be rotated to a predetermined position every time. A relative position with the both end surfaces of a tire constituent member does not shift.
その後、ジョイント装置を成型ドラム１に向けて下降変位させて、図３に示すように、ジッパー４と引き寄せローラ５のそれぞれを、タイヤ構成部材２の巻き始端と巻き終端とのそれぞれに接触させて、ジョイント装置を軸線１ａ方向に前進変位させる。これによりジッパー４は、タイヤ構成部材２の両端面を突き合わせ接合することができる。ここで、タイヤ構成部材２の端部間隔が僅かである時は、ジッパー４だけでもタイヤ構成部材２の両端面を引き寄せることが可能であるが、端部間隔が大きくなると両端面を引き寄せることが困難となる。しかるに本発明においては、ジッパー４よりも前方側に引き寄せローラ５が配設されているので、ジョイント装置の前進変位に伴い、図４に示すようにタイヤ構成部材２の両端部を十分に引き寄せることができ、引き寄せローラ５が通過した部分にジッパー４が到達した際には、タイヤ構成部材２の両端面が接近或いは当接されているので、それらの両端面の突き合わせ接合を確実に行なうことができる。 Thereafter, the joint device is moved downwardly toward the molding drum 1, and the zipper 4 and the pulling roller 5 are brought into contact with the winding start end and the winding end of the tire constituent member 2 as shown in FIG. The joint device is displaced forward in the direction of the axis 1a. Thereby, the zipper 4 can butt-join the both end surfaces of the tire structural member 2. Here, when the distance between the end portions of the tire constituent member 2 is small, it is possible to draw both end surfaces of the tire constituent member 2 with only the zipper 4, but when the end portion interval increases, the both end surfaces may be drawn closer. It becomes difficult. However, in the present invention, the pulling roller 5 is disposed on the front side of the zipper 4, so that both end portions of the tire constituent member 2 are sufficiently pulled as shown in FIG. 4 in accordance with the forward displacement of the joint device. When the zipper 4 reaches the portion through which the drawing roller 5 has passed, both end surfaces of the tire constituent member 2 are approaching or in contact with each other, so that both end surfaces can be reliably butted and joined. it can.
さらに図３に示すように、タイヤ構成部材２に傾斜域２ａが存在することがあっても、図中仮想線で示すように、先行する引き寄せローラ５がこの傾斜部を乗り越え始めると、ジョイント装置は揺動して追従する。このためジッパー４は、この傾斜部をその表面と直角に押し付けることができ、軸線１ａ方向の全長に亘って所期した通りに均一に接合させることができる。 Further, as shown in FIG. 3, even if there is an inclined region 2a in the tire component 2, as shown by the phantom line in the drawing, when the preceding pulling roller 5 starts to get over this inclined portion, the joint device Swings and follows. For this reason, the zipper 4 can press the inclined portion perpendicularly to the surface thereof, and can be uniformly joined as expected over the entire length in the direction of the axis 1a.
このようなジョイント装置を、シングル成型機に付設した場合は、インナーライナーの貼り付けから生タイヤが形成されるまで、一つの成型ドラム上で実施することができるので、より効果的にタイヤの成型を行うことが可能となる。 When such a joint device is attached to a single molding machine, it can be carried out on one molding drum from the application of the inner liner to the formation of the raw tire, so that the molding of the tire is more effective. Can be performed.
また、図５に示すように、引き寄せローラ５を複数対（図５に示す例では、２対）設けた場合には、タイヤ構成部材２の端部間隔がより大きくなっても、両端部を十分に引き寄せることができる。この場合、引き寄せローラ対の対向する小径端の間隔を、より前方側に配置されるものほど大きくする場合には、両端部の間隔がさらに大きくなっても、確実に引き寄せることができる。 Further, as shown in FIG. 5, when a plurality of pairs of pulling rollers 5 (two pairs in the example shown in FIG. 5) are provided, both end portions are arranged even if the end portion interval of the tire constituent member 2 becomes larger. It can be drawn enough. In this case, when the distance between the opposing small diameter ends of the pulling roller pair is increased as the distance between the two ends is increased, the pulling roller pair can be reliably pulled even if the distance between both ends is further increased.
なお、ジョイント装置の軸線１ａ方向の前進変位は、ジッパー４、若しくは引き寄せローラ５の何れか、又はこれらの双方を回転駆動させてもよい。 Note that the forward displacement of the joint device in the direction of the axis 1a may drive either the zipper 4 or the pulling roller 5, or both of them.
