Abstract

PROBLEM TO BE SOLVED: To provide a device for producing a tire constituting member and a method for producing the same, in which the edge parts of a tire constituting member are butted and joined in such a manner that precision of joining and shape at the end parts is highly maintained.SOLUTION: A joining means 30 for the edge parts of a tire constituting member 70 is reciprocated along the edge parts of the tire constituting member 70 by a moving means 10. In each reciprocation, the joining means 30 is brought into contact with the edge part at the middle position between the rear side edge part in the moving direction along the edge part and the central part and is moved to the front side edge part in the moving direction. The end parts are butted and joined by the joining means 30 moving in a reciprocative manner on the end parts of the tire constituting member 70, thus the joined tire constituting member 70 is produced.

本発明は、ゴムで形成されたタイヤ構成部材の端部同士を接合して、接合されたタイヤ構成部材を製造するタイヤ構成部材の製造装置及び製造方法に関する。   The present invention relates to a tire constituent member manufacturing apparatus and a manufacturing method for manufacturing tire joined members by joining ends of tire constituent members made of rubber.

未加硫タイヤの成形に使用されるシート状のタイヤ構成部材、例えばカーカスプライは、成形ドラムに巻き付けられた後に、接合装置により、先後端部が端部に沿って順に突き合せて接合されて筒状に形成される。ところが、タイヤ構成部材の端部の接合を、端部に沿った縁部から開始すると、接合時に作用する力で縁部に変形や変位が生じ易くなり、かつ、縁部のタイヤ構成部材がめくり上げられることがある。その結果、縁部に変形や皺、歪み、位置ずれ等が発生して、縁部付近を中心に、タイヤ構成部材の端部の接合精度が部分的に変化する虞がある。   A sheet-like tire constituent member used for molding an unvulcanized tire, for example, a carcass ply, is wound around a molding drum and joined by a joining device such that the front and rear end portions are sequentially abutted along the end portion. It is formed in a cylindrical shape. However, if the joining of the end portions of the tire constituent member is started from the edge portion along the end portion, the edge portion is likely to be deformed or displaced by the force acting during joining, and the tire constituent member at the edge portion is turned. May be raised. As a result, deformation, wrinkles, distortion, misalignment, and the like occur at the edge, and there is a possibility that the joining accuracy of the end portion of the tire constituent member partially changes around the edge.

これに対し、従来、第１の接合手段によるタイヤ構成部材の端部の接合を縁部よりも内側から開始した後、第２の接合手段による端部の接合を接合済みの部分から開始して、両接合手段を逆方向に移動させ、縁部以外から接合を開始して、縁部での接合精度の向上を図った接合装置が知られている（特許文献１参照）。   On the other hand, conventionally, after joining the end portions of the tire constituent member by the first joining means is started from the inside of the edge portion, joining of the end portions by the second joining means is started from the joined portion. There is known a joining apparatus in which both joining means are moved in the opposite directions and joining is started from other than the edge to improve the joining accuracy at the edge (see Patent Document 1).

しかしながら、この従来の接合装置では、２つの接合手段を使用するとともに、それらの接合開始位置や動作を合わせて互いに同期して作動させる必要があるため、装置の構成や動作が比較的複雑になる傾向がある。また、２つの接合手段の移動による端部の接合長さが大きく異なるため、各接合手段から端部に作用する力の差が比較的大きくなる。その結果、より長く接合される方向に端部が引っ張られて、縁部に変位や変形等が生じ、接合の精度が低下する虞がある。従って、端部同士を確実に突き合わせて接合しつつ、縁部での接合や形状の精度をより高くする観点から、更なる改良が要求されている。   However, in this conventional joining apparatus, since it is necessary to use two joining means and to synchronize the joining start position and operation with each other, the structure and operation of the apparatus become relatively complicated. Tend. Further, since the joining lengths of the end portions due to the movement of the two joining means are greatly different, the difference in force acting on the end portions from each joining means becomes relatively large. As a result, the end portion is pulled in the direction in which the bonding is performed for a longer time, and the edge portion is displaced, deformed, or the like, which may reduce the bonding accuracy. Therefore, further improvement is required from the viewpoint of increasing the accuracy of joining and shape at the edge while reliably joining the end portions together.

By this traveling device 23, the first moving mechanism 20, which is a bead setter, reciprocates along the outer periphery of the forming drum 2, and the bead member held by the holding ring 21 is joined to the tire constituent members at the ends. 70 at predetermined positions. The first moving mechanism 20 has a connecting member 24 fixed to the upper end of the outer periphery of the holding ring 21, and the joining means 30 is connected to the outside in the axial direction of the forming drum 2 by the connecting member 24. . The first moving mechanism 20 moves in the axial direction of the molding drum 2 and moves the joining means 30 in both directions along the end of the tire constituent member 70 to reciprocate.

なお、ビード部材は、少なくともビードコアからなり、未加硫タイヤのビード部に配置される部材であり、ビードコア、又は、ビードコアとビードフィラ等の他の部材からなる。また、ビード部材を配置するときには、第１の移動機構２０は、成形ドラム２よりも駆動装置３側（回転軸４の周り）に配置され、タイヤ構成部材７０が成形ドラム２に巻き付けられた後に、成形ドラム２を挟んだ逆側の軸線方向外側まで移動して、供給されるビード部材を保持する。続いて、第１の移動機構２０は、逆方向に移動して、元の成形ドラム２よりも駆動装置３側の位置に復帰し、ビード部材の配置までビード部材を保持して待機する。製造装置１は、後述するように、この第１の移動機構２０の往復した移動と同時に接合手段３０を往復させつつ、第２の移動機構１１と反転手段１２を作動させて、タイヤ構成部材７０の端部を接合する。   In addition, a bead member consists of at least a bead core, and is a member arrange | positioned at the bead part of an unvulcanized tire, and consists of other members, such as a bead core or a bead core and a bead filler. Further, when the bead member is disposed, the first moving mechanism 20 is disposed closer to the driving device 3 (around the rotation shaft 4) than the molding drum 2, and after the tire constituent member 70 is wound around the molding drum 2. Then, it moves to the outside in the axial direction on the opposite side across the molding drum 2 and holds the supplied bead member. Then, the 1st moving mechanism 20 moves to a reverse direction, returns to the position of the drive device 3 side rather than the original molding drum 2, hold | maintains a bead member and waits until arrangement | positioning of a bead member. As will be described later, the manufacturing apparatus 1 operates the second moving mechanism 11 and the reversing means 12 while reciprocating the joining means 30 simultaneously with the reciprocating movement of the first moving mechanism 20, and thereby the tire constituent member 70. Join the ends.

第２の移動機構１１は、下方に向けて配置されたピストン・シリンダ機構からなり、連結部材２４に固定されたシリンダ１１Ｓと、シリンダ１１Ｓから進退するピストンロッド１１Ｐとを有する。第２の移動機構１１は、ピストンロッド１１Ｐが、成形ドラム２の半径方向に沿って軸線に向けて配置され、ピストンロッド１１Ｐを進退させて、その先端に取り付けられた反転手段１２を成形ドラム２の半径方向に移動させる。これにより、反転手段１２の下端部に固定された接合手段３０を移動（昇降）させて、タイヤ構成部材７０に接近及び離間させる。   The second moving mechanism 11 includes a piston / cylinder mechanism disposed downward, and includes a cylinder 11S fixed to the connecting member 24 and a piston rod 11P that moves forward and backward from the cylinder 11S. In the second moving mechanism 11, the piston rod 11P is arranged toward the axis along the radial direction of the molding drum 2, and the piston rod 11P is moved forward and backward, and the reversing means 12 attached to the tip of the piston rod 11P is moved to the molding drum 2.

反転手段１２は、接合手段３０を回転させる回転機構を有し、回転機構により接合手段３０を１８０°回転させて反転させ、その向きを交互に変更させて、タイヤ構成部材７０の接合時に接合手段３０を移動させるべき方向を切り替える。この反転手段１２は、例えば、空気圧や油圧で作動して回転軸を両方向に回転させ、回転軸に固定された接合手段３０を反転させる回転シリンダからなり、接合手段３０をタイヤ構成部材７０から離間した状態で反転させる。これにより、反転手段１２は、第１の移動機構２０による接合手段３０の移動方向に合わせて接合手段３０を反転させ、接合時の接合手段３０の方向（接合方向）を第１の移動機構２０による移動方向に一致させる。   The reversing means 12 has a rotating mechanism that rotates the joining means 30, and the joining means 30 is rotated 180 ° by the rotating mechanism and reversed, and the direction thereof is changed alternately. Switch the direction in which 30 should be moved. The reversing means 12 is composed of, for example, a rotating cylinder that is operated by air pressure or hydraulic pressure to rotate the rotating shaft in both directions and reverse the joining means 30 fixed to the rotating shaft, and the joining means 30 is separated from the tire constituent member 70. Invert in the state. Accordingly, the reversing unit 12 reverses the joining unit 30 in accordance with the moving direction of the joining unit 30 by the first moving mechanism 20, and changes the direction (joining direction) of the joining unit 30 at the time of joining to the first moving mechanism 20. Match the direction of movement.

移動手段１０は、第２の移動機構１１により、接合手段３０を、タイヤ構成部材７０の端部に接触及び離間させるとともに、接合手段３０をタイヤ構成部材７０の端部に所定圧力で押し付けて端部を押圧させる。また、反転手段１２により、接合手段３０を適宜反転させて、第１の移動機構２０により、接合手段３０をタイヤ構成部材７０の端部に沿って両方向に移動させる。ここでは、移動手段１０は、上記のように、第１の移動機構２０が、接合手段３０が設けられたビードセッターからなり、ビードセッターにより接合手段３０をタイヤ構成部材７０の端部に沿って移動させて往復させる。製造装置１は、これら移動手段１０の第１と第２の移動機構２０、１１と反転手段１２とを所定のパターンで作動させて、往復移動する接合手段３０により、タイヤ構成部材７０の端部同士を接合する。   The moving means 10 uses the second moving mechanism 11 to bring the joining means 30 into contact with and away from the end of the tire constituent member 70 and press the joining means 30 against the end of the tire constituent member 70 with a predetermined pressure. Press the part. Further, the joining means 30 is appropriately reversed by the reversing means 12, and the joining means 30 is moved in both directions along the end portion of the tire constituent member 70 by the first moving mechanism 20. Here, as described above, the moving means 10 includes the bead setter in which the first moving mechanism 20 is provided with the joining means 30, and the joining means 30 is moved along the end of the tire constituent member 70 by the bead setter. Move and reciprocate.

In this state, the pressing roller 32 is pressed against both end portions 71, 72 of the tire constituent member 70, and presses the end portions 71, 72 in the contact range between the forming drum 2. The joining means 30 presses both end portions 71 and 72 with the pressing roller 32 and sequentially joins the end portions 71 and 72 with each pair of joining rollers 40.

図３は、１つの接合ローラ４０を半径方向外側から見た正面図であり、その一部（図の上方部）を断面で示している。
接合ローラ４０の外周には、図示のように、周方向に延びる突条Ｔが、環状に、又は螺旋状に複数並列して形成され、全体の断面形状が、複数の突出部が並んだ鋸歯状に形成されている。突条Ｔは、突起４１側の側面が接合ローラ４０の軸線方向と直交し、他方側の側面が所定角度で傾斜する断面三角形状に形成され、接合ローラ４０の突起４１を含む外周の全体に亘って配置されている。接合ローラ４０は、これら各突条Ｔがタイヤ構成部材７０の端部７１、７２に当接して、端部７１、７２の所定範囲に押し付けられる。 FIG. 3 is a front view of one joining roller 40 as viewed from the outside in the radial direction, and shows a part (upper part in the drawing) in cross section.
On the outer periphery of the joining roller 40, as shown in the figure, a plurality of protrusions T extending in the circumferential direction are formed in parallel in a ring shape or in a spiral shape, and the entire cross-sectional shape is a saw tooth in which a plurality of protrusions are arranged. It is formed in a shape. The ridge T is formed in a triangular cross-section in which the side surface on the projection 41 side is orthogonal to the axial direction of the joining roller 40 and the other side surface is inclined at a predetermined angle, and is formed on the entire outer periphery including the projection 41 of the joining roller 40. It is arranged over. The joining roller 40 is pressed against a predetermined range of the end portions 71 and 72 by the protrusions T coming into contact with the end portions 71 and 72 of the tire constituent member 70.

製造装置１は、上記した移動手段１０（図１参照）により接合手段３０を移動させ、押さえローラ３２（図２参照）をタイヤ構成部材７０の両端部７１、７２に、各接合ローラ４０Ａ、４０Ｂを、それぞれ端部７１、７２に間隙Ｒを挟んで対称に押し付けて当接させる。その状態で、接合手段３０を端部７１、７２に沿って接合方向Ｓに移動させ、押さえローラ３２で両端部７１、７２を順次押さえながら、互いに逆方向に傾斜した接合ローラ４０Ａ、４０Ｂを同期して各端部７１、７２の表面上を転動させる。   The manufacturing apparatus 1 moves the joining means 30 by the above-described moving means 10 (see FIG. 1), and the pressing roller 32 (see FIG. 2) is attached to both end portions 71 and 72 of the tire constituent member 70 to each joining roller 40A, 40B. Are pressed against the end portions 71 and 72 symmetrically with the gap R interposed therebetween. In this state, the joining means 30 is moved in the joining direction S along the end portions 71 and 72, and the joining rollers 40A and 40B inclined in opposite directions are synchronized while the both end portions 71 and 72 are sequentially pressed by the pressing roller 32. Then, it rolls on the surface of each end 71, 72.

この傾斜した接合ローラ４０Ａ、４０Ｂの転動に伴い、各端部７１、７２に、接合ローラ４０Ａ、４０Ｂの突条Ｔから直交する方向の力が加えられる等して、互いに接近する方向の力が作用する。これにより、両端部７１、７２が互いに引き寄せられて、間隙Ｒを消滅させながら突き合わされ、接合ローラ４０Ａ、４０Ｂからの圧力で端面同士が圧着する。同時に、接合ローラ４０Ａ、４０Ｂの互いに噛み合う突起４１Ａ、４１Ｂから端部７１、７２に交互に力が作用し、端部７１、７２の表面が交互に他方側に向かって弾性変形して継ぎ合わされ、端部７１、７２同士が接合される。   Along with the rolling of the inclined joining rollers 40A and 40B, forces in directions approaching each other are applied to the end portions 71 and 72 by a force in a direction orthogonal to the protrusion T of the joining rollers 40A and 40B. Act. Thereby, both ends 71 and 72 are attracted to each other and are abutted while eliminating the gap R, and the end faces are pressure-bonded by pressure from the joining rollers 40A and 40B. At the same time, forces are alternately applied to the end portions 71 and 72 from the engaging protrusions 41A and 41B of the joining rollers 40A and 40B, and the surfaces of the end portions 71 and 72 are alternately elastically deformed toward the other side and joined together. The ends 71 and 72 are joined together.

図４は、接合後のタイヤ構成部材７０の接合部７３付近を示す模式図であり、図４Ａは斜視図、図４Ｂは図４ＡのＹ−Ｙ線矢視断面図である。
図示のように、複数のコードＣを有するタイヤ構成部材７０は、接合により、端部７１、７２の表面側（図４では上側）のゴム７３Ｗが、突起４１Ａ、４１Ｂにより交互に他方側の端部７１、７２の表面まで部分的に引き伸ばされる。その結果、接合部７３は、内側（図４では下側）の直線的に圧着された部分に対し、表面側の端部７１、７２が、交互に他方側の表面に重なり合い、波状をなして接合される。 4A and 4B are schematic views showing the vicinity of the joining portion 73 of the tire constituent member 70 after joining, FIG. 4A is a perspective view, and FIG. 4B is a cross-sectional view taken along line YY in FIG. 4A.
As shown in the figure, the tire constituting member 70 having a plurality of cords C is joined so that the rubber 73W on the surface side (the upper side in FIG. 4) of the end portions 71 and 72 is alternately turned to the other end by the protrusions 41A and 41B. Partially stretched to the surface of the parts 71, 72. As a result, the joining portion 73 has a wave-like shape in which the end portions 71 and 72 on the surface side alternately overlap the surface on the other side with respect to the linearly crimped portion on the inner side (lower side in FIG. 4). Be joined.

このように、製造装置１は、一対の接合ローラ４０（図２参照）を、間隙Ｒを挟んでタイヤ構成部材７０の各端部７１、７２に当接させ、それぞれ各端部７１、７２上を転動させる。この転動する接合ローラ４０により、両端部７１、７２を互いに引き寄せながら端部７１、７２同士（両端面）を突き合わせ、タイヤ構成部材７０を連続して接合して、タイヤ構成部材７０を筒状に形成する。その際、製造装置１は、移動手段１０で前後２組みの接合ローラ４０を連動して転動させ、それらにより連続して同様の接合動作を実行させて、端部７１、７２を接合する。   As described above, the manufacturing apparatus 1 causes the pair of joining rollers 40 (see FIG. 2) to abut on the end portions 71 and 72 of the tire constituent member 70 with the gap R interposed therebetween, and on the end portions 71 and 72, respectively. Roll. The rolling joining roller 40 causes the end portions 71 and 72 (both end faces) to abut each other while pulling the both end portions 71 and 72 together, and the tire constituent member 70 is continuously joined. To form. At that time, the manufacturing apparatus 1 causes the front and rear two sets of joining rollers 40 to roll in conjunction with the moving means 10, and continuously performs the same joining operation by them to join the ends 71 and 72.

本実施形態の製造装置１は、この接合ローラ４０による接合に続けて、補強ローラ５０（図２参照）により、タイヤ構成部材７０の接合部７３を押圧等して、端部７１、７２同士の接合を補強する。補強ローラ５０は、円柱状に形成されて、枠体３１に取り付けられた軸部材３４により軸線周りに回転自在に支持され、押さえローラ３２及び接合ローラ４０とともに、タイヤ構成部材７０に押し付けられて当接する。その状態で、補強ローラ５０は、接合部７３を挟んで両側に配置されて、突き合わされたタイヤ構成部材７０の両側の端部７１、７２に当接し、両端部７１、７２の所定範囲を同等の圧力で押圧する。また、補強ローラ５０は、接合手段３０の移動に伴い、接合ローラ４０の後方に続いて接合方向Ｓに移動して、接合された端部７１、７２上を転動する。   The manufacturing apparatus 1 of the present embodiment presses the joining portion 73 of the tire constituent member 70 with the reinforcing roller 50 (see FIG. 2) subsequent to the joining by the joining roller 40, so that the end portions 71 and 72 are connected to each other. Reinforce the joint. The reinforcing roller 50 is formed in a cylindrical shape and is supported rotatably around the axis by a shaft member 34 attached to the frame body 31, and is pressed against the tire component member 70 together with the pressing roller 32 and the joining roller 40. Touch. In this state, the reinforcing roller 50 is disposed on both sides with the joint 73 interposed therebetween, abuts against the ends 71 and 72 on both sides of the tire component 70 abutted against each other, and the predetermined ranges of both ends 71 and 72 are equal. Press with pressure of. Further, as the joining means 30 moves, the reinforcing roller 50 moves in the joining direction S following the joining roller 40 and rolls on the joined end portions 71 and 72.

このように、補強ローラ５０は、回転しつつ端部７１、７２上を転動する回転体（又は、転動体）であり、タイヤ構成部材７０に当接する外周面が、端部７１、７２の界面を磨り潰すように、それらの表面を摩擦する摩擦面５１になっている。摩擦面５１は、全体に亘り、補強ローラ５０の回転方向に対して傾斜した方向に配置された複数の凸条や凹溝、又は、傾斜した方向に並べて配置された複数の凸起や凹みが設けられている。これにより、摩擦面５１は、タイヤ構成部材７０の表面に当接して押し付けられたときに、ゴムに押し込まれる凹凸が形成された凹凸面に、かつ、ゴムとの摩擦力が大きい粗面に形成される。また、ここでは、摩擦面５１は、傾斜した複数の凹溝が交差して形成されてローレット加工が施され、ローレット加工面の凹溝と、凹溝間の複数の凸起で端部７１、７２に当接する。   As described above, the reinforcing roller 50 is a rotating body (or rolling element) that rolls on the end portions 71 and 72 while rotating, and the outer peripheral surface that contacts the tire constituent member 70 is the end portion 71 or 72. The friction surface 51 rubs the surfaces so as to polish the interface. The friction surface 51 has a plurality of protrusions and grooves arranged in a direction inclined with respect to the rotation direction of the reinforcing roller 50 or a plurality of protrusions and depressions arranged side by side in the inclined direction. Is provided. As a result, the friction surface 51 is formed on the uneven surface where the unevenness to be pushed into the rubber is formed when pressed against the surface of the tire constituent member 70 and on the rough surface having a large frictional force with the rubber. Is done. Further, here, the friction surface 51 is formed by intersecting a plurality of inclined concave grooves and subjected to knurl processing, and the end portion 71 with the concave grooves of the knurl processing surface and the plurality of protrusions between the concave grooves, 72 abuts.

この補強ローラ５０は、摩擦面５１で、接合されたタイヤ構成部材７０の両端部７１、７２（接合部７３）を押圧しつつ両端部７１、７２上を転動する。同時に、摩擦面５１が有する回転方向に対して傾斜した方向に配置された複数の凸部又は凹部を両端部７１、７２に当接させ、補強ローラ５０の転動に伴い、摩擦面５１により、突き合わされた両端部７１、７２を摩擦する。これにより、補強ローラ５０は、タイヤ構成部材７０の両端部７１、７２を、押圧の圧力で互いに相手側に向けて膨出するように変形させて、より強く圧着させる。また、補強ローラ５０は、ローレット加工を施した摩擦面５１で両端部７１、７２を摩擦し、その表面のゴムを押圧して互いに流動等させることで、両端部７１、７２の接合の界面をゴムで埋めつつ界面を潰し、摩擦された表面側を中心に界面を消滅させる。このように、補強ローラ５０は、転動に伴い、タイヤ構成部材７０の両端部７１、７２の接合界面を磨り潰すようにして、端部７１、７２同士の接合を順次補強し、それらを強固に接合させる。   The reinforcing roller 50 rolls on both end portions 71 and 72 while pressing the both end portions 71 and 72 (joint portion 73) of the joined tire constituent member 70 with the friction surface 51. At the same time, a plurality of convex portions or concave portions arranged in a direction inclined with respect to the rotational direction of the friction surface 51 are brought into contact with both end portions 71 and 72, and the friction surface 51 The both end portions 71 and 72 that are abutted against each other are rubbed. As a result, the reinforcing roller 50 deforms both end portions 71 and 72 of the tire constituent member 70 so as to bulge toward each other with the pressure of the pressure, and press-bonds more strongly. Further, the reinforcing roller 50 rubs the both end portions 71 and 72 with the friction surface 51 subjected to the knurling process, and presses the rubber on the surface to flow and so on, so that the joining interface between the both end portions 71 and 72 is made. The interface is crushed while being filled with rubber, and the interface disappears around the rubbed surface. In this manner, the reinforcing roller 50 sequentially reinforces the joining between the end portions 71 and 72 so as to polish the joining interface between the both end portions 71 and 72 of the tire constituent member 70 with rolling, thereby strengthening them firmly. To be joined.

また、製造装置１は、補強ローラ５０の内部に設けられた、又は、外部から補強ローラ５０を加熱する加熱ヒータと、補強ローラ５０の摩擦面５１の温度を測定する温度センサ等からなる加熱手段（図示せず）を備えている。製造装置１は、この加熱手段により、温度センサによる温度の測定結果に基づき、補強ローラ５０の摩擦面５１を所定温度（例えば、５０〜８０℃）に加熱して温度を維持し、押圧（摩擦）位置のタイヤ構成部材７０の両端部７１、７２を加熱して、その付近のゴムを軟らかくする。これにより、ゴムの流動性を高くして、補強ローラ５０による両端部７１、７２の接合界面を埋める効果や磨り潰す効果を高くし、補強ローラ５０による補強を補助して、より強固に、高い接合強度で端部７１、７２同士を接合させる。   Further, the manufacturing apparatus 1 includes a heater provided inside the reinforcing roller 50 or a heater that heats the reinforcing roller 50 from the outside, a temperature sensor that measures the temperature of the friction surface 51 of the reinforcing roller 50, and the like. (Not shown). The manufacturing apparatus 1 uses this heating means to heat the friction surface 51 of the reinforcing roller 50 to a predetermined temperature (for example, 50 to 80 ° C.) based on the temperature measurement result by the temperature sensor to maintain the temperature and press (friction) ) Heat both ends 71 and 72 of the tire constituent member 70 at a position to soften the rubber in the vicinity thereof. Thereby, the fluidity of the rubber is increased, the effect of filling the bonding interface between the end portions 71 and 72 by the reinforcing roller 50 and the effect of crushing are increased, the reinforcement by the reinforcing roller 50 is assisted, and the strength is increased. The ends 71 and 72 are joined together with the joining strength.

以上のように、接合手段３０は、複数のローラ（押さえローラ３２、接合ローラ４０、及び、補強ローラ５０）を有する接合ユニットであり、各ローラ３２、４０、５０が回転しつつ移動してタイヤ構成部材７０の両端部７１、７２上を転動する。この転動するローラ３２、４０、５０を介して、接合手段３０は、接合するタイヤ構成部材７０の両側の端部７１、７２上を移動して、上記のように、端部７１、７２同士を引き寄せながら突き合わせて接合する。   As described above, the joining means 30 is a joining unit having a plurality of rollers (the pressing roller 32, the joining roller 40, and the reinforcing roller 50), and each of the rollers 32, 40, and 50 is moved while rotating to tire. Rolls on both ends 71 and 72 of the component 70. Via the rolling rollers 32, 40, 50, the joining means 30 moves on the end portions 71, 72 on both sides of the tire constituent member 70 to be joined, and as described above, the end portions 71, 72 are connected to each other. Butt and join together.

製造装置１は、接合手段３０による接合動作を、移動手段１０等の装置各部を制御する制御手段である制御装置６０（図１参照）により制御して行う。制御装置６０は、例えばマイクロプロセッサ（ＭＰＵ）６１と、各種制御処理のためのプログラムを格納するＲＯＭ（Read Only Memory）６２と、ＭＰＵ６１が直接アクセスするデータを一時的に格納するＲＡＭ（Random Access Memory）６３を備えたマイクロコンピュータを有する。また、制御装置６０は、接続手段を介して装置各部が接続されており、接続された各部を制御して予め設定されたタイミングや条件で関連動作させて、接合のための各動作を実行させる。   The manufacturing apparatus 1 performs the joining operation by the joining means 30 by controlling with a control device 60 (see FIG. 1) which is a control means for controlling each part of the apparatus such as the moving means 10. The control device 60 includes, for example, a microprocessor (MPU) 61, a ROM (Read Only Memory) 62 that stores programs for various control processes, and a RAM (Random Access Memory) that temporarily stores data that the MPU 61 directly accesses. A microcomputer having 63 is provided. In addition, the control device 60 is connected to each part of the device via the connection means, and controls each connected part to perform a related operation at a preset timing and condition to execute each operation for joining. .

次に、製造装置１により、タイヤ構成部材７０の端部７１、７２同士を接合する手順や、端部７１、７２が接合されたタイヤ構成部材７０の製造方法について説明する。タイヤ構成部材７０（図１参照）を接合するときには、まず、その内側に配置されるインナーライナ等の部材を成形ドラム２の外周に配置した後、タイヤ構成部材７０を回転する成形ドラム２の外周に１周巻き付ける。また、タイヤ構成部材７０の両端部７１、７２を、移動手段１０による接合手段３０の押し付け位置に配置して、成形ドラム２で端部７１、７２同士を対向させて支持する。   Next, a procedure for joining the end portions 71 and 72 of the tire constituent member 70 with the manufacturing apparatus 1 and a method for producing the tire constituent member 70 joined with the end portions 71 and 72 will be described. When joining the tire constituent member 70 (see FIG. 1), first, an inner liner or other member disposed inside the tire constituent member 70 is disposed on the outer periphery of the molding drum 2, and then the outer periphery of the molding drum 2 that rotates the tire constituent member 70. Wrap one turn around. Further, both end portions 71, 72 of the tire constituent member 70 are arranged at the pressing position of the joining means 30 by the moving means 10, and the end portions 71, 72 are opposed to each other and supported by the molding drum 2.

続いて、ビードセッターを兼ねる第１の移動機構２０を、上記のように、成形ドラム２の駆動装置３側から逆側に移動させて、保持リング２１によりビード部材を保持し、第１の移動機構２０を元の駆動装置３側に移動させて待機させる。製造装置１は、第１の移動機構２０が成形ドラム２の軸線方向外側間で移動するときに、接合手段３０を同時に往復して移動させ、同時に、第２の移動機構１１と反転手段１２を上記のように作動させる。製造装置１は、これら第１の移動機構２０、第２の移動機構１１、反転手段１２からなる移動手段１０により接合手段３０を移動や反転させて、タイヤ構成部材７０の端部７１、７２を接合する。   Subsequently, the first moving mechanism 20 also serving as a bead setter is moved from the driving device 3 side of the forming drum 2 to the opposite side as described above, the bead member is held by the holding ring 21, and the first movement is performed. The mechanism 20 is moved to the original driving device 3 side to be on standby. When the first moving mechanism 20 moves between the outsides of the forming drum 2 in the axial direction, the manufacturing apparatus 1 moves the joining means 30 back and forth at the same time, and simultaneously moves the second moving mechanism 11 and the reversing means 12. Operate as above. The manufacturing apparatus 1 moves or reverses the joining means 30 by the moving means 10 including the first moving mechanism 20, the second moving mechanism 11, and the reversing means 12, so that the end portions 71 and 72 of the tire constituent member 70 are moved. Join.

図５は、タイヤ構成部材７０を接合する過程を順に示す要部平面図であり、図１の矢印Ｚ方向から見た成形ドラム２と接合手段３０を示している。また、図５では、端部７１、７２の両側のタイヤ構成部材７０と、その付近の成形ドラム２を抜き出して模式的に示している。
製造装置１は、移動手段１０により、接合手段３０（図５Ａ参照）をタイヤ構成部材７０から離間させた状態で移動させ、タイヤ構成部材７０の端部７１、７２に沿った一方の縁部７４を通過させる。続いて、接合手段３０を、一方の縁部７４と中央部７５の間の所定位置で下降させて端部７１、７２に接触させる。 FIG. 5 is a plan view of a main part sequentially illustrating the process of joining the tire constituent members 70, and shows the forming drum 2 and the joining means 30 viewed from the direction of arrow Z in FIG. FIG. 5 schematically shows the tire constituent members 70 on both sides of the end portions 71 and 72 and the molding drum 2 in the vicinity thereof.
The manufacturing apparatus 1 uses the moving means 10 to move the joining means 30 (see FIG. 5A) in a state of being separated from the tire constituent member 70, and one edge 74 along the ends 71 and 72 of the tire constituent member 70. Pass through. Subsequently, the joining means 30 is lowered at a predetermined position between the one edge portion 74 and the central portion 75 and brought into contact with the end portions 71 and 72.

なお、ここでは、タイヤ構成部材７０の中央部７５は、成形ドラム２の中央部ＣＬと一致している。また、接合手段３０は、一方の縁部７４と中央部７５の間の途中位置、即ち、縁部７４よりも中央部７５側で、かつ、中央部７５よりも縁部７４側の位置に設定された接触開始位置Ｍ１で端部７１、７２への接触を開始する。これにより、製造装置１は、接合手段３０の各ローラ３２、４０、５０を、タイヤ構成部材７０に所定圧力で押し付け、押さえローラ３２で端部７１、７２を押さえ、接合ローラ４０の外周部（突条Ｔの突端部）と、補強ローラ５０の摩擦面５１を、タイヤ構成部材７０の各端部７１、７２に当接させる。   Here, the central portion 75 of the tire constituent member 70 coincides with the central portion CL of the molding drum 2. Further, the joining means 30 is set at a midway position between the one edge portion 74 and the center portion 75, that is, at a position closer to the center portion 75 than the edge portion 74 and closer to the edge portion 74 than the center portion 75. The contact to the end portions 71 and 72 is started at the contact start position M1. Thus, the manufacturing apparatus 1 presses the rollers 32, 40, 50 of the joining means 30 against the tire constituent member 70 with a predetermined pressure, presses the end portions 71, 72 with the pressing roller 32, and The protruding end portion of the protrusion T and the friction surface 51 of the reinforcing roller 50 are brought into contact with the end portions 71 and 72 of the tire constituent member 70.

次に、製造装置１は、接合手段３０を、タイヤ構成部材７０の端部７１、７２に接触した状態で接合方向Ｓに移動させて、端部７１、７２に沿って他方の縁部７６まで移動（図５Ａの矢印Ｈ１）させる。その際、一対の接合ローラ４０が、タイヤ構成部材７０の各端部７１、７２上を転動して、両端部７１、７２を引き寄せながら端部７１、７２同士を突き合わせて接合する。また、突き合わせた両端部７１、７２を、加熱した補強ローラ５０の摩擦面５１で押圧しつつ加熱し、補強ローラ５０を両端部７１、７２（接合部７３）上を転動させて、上記のように端部７１、７２同士の接合を補強する。これにより、接合手段３０が移動した範囲（接触開始位置Ｍ１から他方の縁部７６までの範囲）で、端部７１、７２同士を接合した後、成形ドラム２の軸線方向外側で、接合手段３０を上昇させて反転（図５Ｂの矢印Ｋ１）させる。   Next, the manufacturing apparatus 1 moves the joining means 30 in the joining direction S in a state where the joining means 30 is in contact with the end portions 71 and 72 of the tire constituent member 70, and reaches the other edge portion 76 along the end portions 71 and 72. Move (arrow H1 in FIG. 5A). At that time, the pair of joining rollers 40 roll on the respective end portions 71 and 72 of the tire constituent member 70 to bring the end portions 71 and 72 into contact with each other while pulling the both end portions 71 and 72 together. Further, both end portions 71 and 72 that are abutted are heated while being pressed by the friction surface 51 of the heated reinforcing roller 50, and the reinforcing roller 50 is rolled on both end portions 71 and 72 (joint portion 73), thereby Thus, the joining of the end portions 71 and 72 is reinforced. Thereby, after joining the edge parts 71 and 72 in the range (range from the contact start position M1 to the other edge part 76) which the joining means 30 moved, the joining means 30 is carried out on the axial direction outer side of the forming drum 2. Is raised and reversed (arrow K1 in FIG. 5B).

続いて、製造装置１は、以上と同様に、接合手段３０（図５Ｃ参照）をタイヤ構成部材７０から離間させた状態で移動させて、他方の縁部７６と中央部７５の間の所定位置（接触開始位置Ｍ２）で端部７１、７２に接触させる。次に、接合手段３０を、タイヤ構成部材７０の端部７１、７２に接触した状態で接合方向Ｓに移動させて、端部７１、７２に沿って一方の縁部７４まで移動（図５Ｃの矢印Ｈ２）させる。同時に、各ローラ３２、４０、５０を転動させて、接合手段３０が移動した範囲（接触開始位置Ｍ２から一方の縁部７４までの範囲）で端部７１、７２同士を接合する。その際、接合手段３０は、既に接合された部分から接合を開始しており、中央部７５を挟んだ範囲（両接触開始位置Ｍ１、Ｍ２間の範囲）において、往復時で重ねて接合の動作を行う。次に、接合手段３０の移動を停止して上昇させ、接合手段３０を反転（図５Ｄの矢印Ｋ２）させて、接合手段３０と移動手段１０を、接合動作を開始する前の元の位置及び状態で待機させる。   Subsequently, similarly to the above, the manufacturing apparatus 1 moves the joining means 30 (see FIG. 5C) in a state of being separated from the tire constituent member 70, and a predetermined position between the other edge portion 76 and the central portion 75. The end portions 71 and 72 are brought into contact with each other at (contact start position M2). Next, the joining means 30 is moved in the joining direction S while being in contact with the end portions 71 and 72 of the tire constituent member 70, and is moved to one edge portion 74 along the end portions 71 and 72 (in FIG. 5C). Arrow H2). At the same time, the rollers 32, 40, 50 are rolled to join the end portions 71, 72 to each other in the range in which the joining means 30 has moved (range from the contact start position M 2 to one edge 74). At that time, the joining means 30 has started joining from the already joined portion, and in the range sandwiching the central portion 75 (range between both contact start positions M1 and M2), the joining operation is overlapped during reciprocation. I do. Next, the movement of the joining means 30 is stopped and raised, the joining means 30 is reversed (arrow K2 in FIG. 5D), and the joining means 30 and the moving means 10 are moved to the original positions before starting the joining operation. Wait in state.

このように、製造装置１は、接合手段３０の位置をセンサ（図示せず）等により検知しつつ、制御装置６０により移動手段１０を制御して、接合手段３０を、タイヤ構成部材７０の端部７１、７２に沿って往復して移動させる。また、往復のそれぞれで、接合手段３０を、端部７１、７２に沿った移動方向の後方側縁部（７４又は７６）と中央部７５の間の途中位置で端部７１、７２に接触させ、接合手段３０を、端部７１、７２に沿って移動方向の前方側縁部（７４又は７６）まで移動させる。この端部７１、７２上を往復して移動する接合手段３０により、各移動方向で端部７１、７２同士を順に突き合わせて接合し、それらを全体に亘って隙間無く接合する。   As described above, the manufacturing apparatus 1 controls the moving means 10 by the control device 60 while detecting the position of the joining means 30 with a sensor (not shown) or the like, so that the joining means 30 is connected to the end of the tire constituent member 70. Reciprocate along the portions 71 and 72. Further, in each reciprocation, the joining means 30 is brought into contact with the end portions 71 and 72 at a midway position between the rear side edge portion (74 or 76) in the movement direction along the end portions 71 and 72 and the central portion 75. Then, the joining means 30 is moved along the end portions 71 and 72 to the front side edge portion (74 or 76) in the moving direction. By the joining means 30 that reciprocally moves on the end portions 71 and 72, the end portions 71 and 72 are sequentially abutted and joined in the respective moving directions, and they are joined together without any gap.

ここで、本実施形態では、接合手段３０の接触開始位置Ｍ１、Ｍ２が、タイヤ構成部材７０の中央部７５を挟んだ対称な位置に設定されており、往復時の接合手段３０は、中央部７５を挟んだ対称な途中位置で端部７１、７２に接触して対称な状態で移動する。即ち、制御装置６０は、移動手段１０を制御して、接合手段３０を、端部７１、７２に沿って逆方向に順に移動させ、かつ、往復の折り返し時に反転させて、接合手段３０を、往復時で互いに対称に移動させるようになっている。また、接合手段３０の接触開始位置Ｍ１、Ｍ２は、上記したサイドブラダ５に対し、その成形ドラム２の軸線方向内側に位置する端部５Ｔよりも成形ドラム２の中央部ＣＬ側に設定されている。そのため、制御装置６０は、往復時の接合手段３０を、サイドブラダ５よりも成形ドラム２の軸線方向の中央部ＣＬ側であり、成形ドラム２のサイドブラダ５以外の外周部分で、タイヤ構成部材７０の端部７１、７２に接触させて移動させる。   Here, in this embodiment, the contact start positions M1 and M2 of the joining means 30 are set to symmetrical positions with the central portion 75 of the tire constituent member 70 interposed therebetween, and the joining means 30 during reciprocation is the central portion. It moves in a symmetrical state in contact with the end portions 71 and 72 at a symmetrical halfway position with 75 interposed therebetween. That is, the control device 60 controls the moving means 10 to sequentially move the joining means 30 along the end portions 71 and 72 in the reverse direction, and to reverse at the time of reciprocation, the joining means 30 is They are moved symmetrically with each other during reciprocation. Further, the contact start positions M1 and M2 of the joining means 30 are set closer to the central portion CL side of the molding drum 2 than the end portion 5T located on the inner side in the axial direction of the molding drum 2 with respect to the side bladder 5 described above. . Therefore, the control device 60 has the joining means 30 at the time of reciprocation closer to the center portion CL side in the axial direction of the molding drum 2 than the side bladder 5, and at the outer peripheral portion of the molding drum 2 other than the side bladder 5, The end portions 71 and 72 are moved in contact with each other.

製造装置１（図１参照）は、接合手段３０により、ゴムで形成されたタイヤ構成部材７０の端部７１、７２同士を接合して、接合されたタイヤ構成部材７０を製造する。また、ビードセッターである第１の移動機構２０を移動させて、ビード部材をタイヤ構成部材７０の一方の縁部７４側の外周に配置し、他方の縁部７６側にも、同様のビードセッターによりビード部材を配置する。その後、タイヤ構成部材７０に他のタイヤ構成部材を配置する等して、所定形状及び構造の未加硫タイヤが成形され、未加硫タイヤを加硫成型して各種のタイヤが製造される。   The manufacturing apparatus 1 (see FIG. 1) uses the joining means 30 to join the end portions 71 and 72 of the tire constituent member 70 made of rubber to manufacture the joined tire constituent member 70. Moreover, the 1st moving mechanism 20 which is a bead setter is moved, a bead member is arrange | positioned on the outer periphery of the one edge part 74 side of the tire structural member 70, and the same bead setter is also arranged on the other edge part 76 side. The bead member is arranged by the above. Thereafter, an unvulcanized tire having a predetermined shape and structure is formed by arranging another tire constituent member on the tire constituent member 70, and various tires are manufactured by vulcanizing and molding the unvulcanized tire.

以上説明したように、本実施形態では、接合手段３０を、タイヤ構成部材７０の端部７１、７２に沿った縁部７４、７６と中央部７５の間の途中位置で端部７１、７２に接触させ、中央部７５を挟んだ逆側の縁部７４、７６まで移動させて、端部７１、７２同士を接合する。このように、端部７１、７２の縁部７４、７６以外から接合を開始するため、縁部７４、７６に変形や変位が生じ難くなり、縁部７４、７６が接合手段３０のローラ３２、４０、５０に巻き付く等して、めくり上げられるのも防止できる。これにより、縁部７４、７６に変形や皺、歪み、位置ずれ等が発生するのを抑制して、端部７１、７２同士を確実に突き合わせて接合でき、端部７１、７２同士の接合精度の均一性を向上できる。   As described above, in this embodiment, the joining means 30 is connected to the end portions 71 and 72 at a midway position between the edge portions 74 and 76 and the central portion 75 along the end portions 71 and 72 of the tire constituent member 70. The end portions 71 and 72 are joined to each other by moving to the opposite edge portions 74 and 76 sandwiching the central portion 75. Thus, since joining is started from other than the edges 74 and 76 of the ends 71 and 72, the edges 74 and 76 are less likely to be deformed or displaced, and the edges 74 and 76 become the rollers 32 of the joining means 30. It is also possible to prevent the paper from being turned up by being wound around 40 or 50. Accordingly, the edge portions 74 and 76 can be prevented from being deformed, wrinkled, distorted, misaligned, and the like, and the end portions 71 and 72 can be reliably brought into contact with each other. Can improve the uniformity.

また、１つの接合手段３０を往復させてタイヤ構成部材７０の端部７１、７２を接合するため、製造装置１の構成を簡単にできる。同時に、複数の接合手段で接合するときには、接合手段の位置や動作を合わせて互いに同期して作動させる必要があるが、この製造装置１では、それらが不要となり、簡単な動作で円滑に端部７１、７２同士を接合できる。更に、往復時における接合手段３０による端部７１、７２の接合長さが比較的近くなるため、往復時に接合手段３０から端部７１、７２に作用する力の差と、端部７１、７２が各接合方向に変位する量の差を低減できる。その結果、端部７１、７２が一方に引っ張られて、縁部７４、７６に変位や変形等が生じるのを抑制でき、縁部７４、７６での接合や形状の精度をより高くできる。   Moreover, since the joining means 30 is reciprocated to join the end portions 71 and 72 of the tire constituent member 70, the configuration of the manufacturing apparatus 1 can be simplified. At the same time, when joining with a plurality of joining means, it is necessary to synchronize the positions and operations of the joining means and to operate them in synchronization with each other. 71 and 72 can be joined. Furthermore, since the joining lengths of the end portions 71 and 72 by the joining means 30 at the time of reciprocation are relatively close, the difference in force acting on the end portions 71 and 72 from the joining means 30 at the time of reciprocation and the end portions 71 and 72 are The difference in the amount of displacement in each joining direction can be reduced. As a result, the end portions 71 and 72 are pulled to one side, and it is possible to suppress the displacement and deformation of the edge portions 74 and 76, and the accuracy of joining and shape at the edge portions 74 and 76 can be further increased.

従って、本実施形態によれば、簡単な構成や動作で、タイヤ構成部材７０の端部７１、７２同士を、縁部７４、７６での接合や形状の精度を高く維持して確実に突き合わせて接合でき、接合の精度を向上させることができる。また、接合手段３０を端部７１、７２上を移動させることで端部７１、７２同士を接合できるため、成形ドラム２上でも、タイヤ構成部材７０の端部７１、７２を確実に接合できる。そのため、この製造装置１は、成形ドラム２に巻き付けたタイヤ構成部材７０を接合するのに好適であり、その際に大きな効果が得られる。更に、接合手段３０に補強ローラ５０を設けるときには、上記のように、タイヤ構成部材７０の端部７１、７２同士の接合を補強して、タイヤ構成部材７０の端部７１、７２同士を、より高い接合強度で確実に接合できる。   Therefore, according to the present embodiment, the end portions 71 and 72 of the tire constituent member 70 are reliably abutted with each other while maintaining high joining and shape accuracy at the edge portions 74 and 76 with a simple configuration and operation. Bonding can be performed and the accuracy of bonding can be improved. Further, since the end portions 71 and 72 can be joined to each other by moving the joining means 30 on the end portions 71 and 72, the end portions 71 and 72 of the tire constituent member 70 can be reliably joined even on the molding drum 2. Therefore, this manufacturing apparatus 1 is suitable for joining the tire constituent member 70 wound around the forming drum 2, and a great effect is obtained at that time. Further, when the reinforcing roller 50 is provided in the joining means 30, as described above, the joining between the end portions 71 and 72 of the tire constituent member 70 is reinforced, and the end portions 71 and 72 of the tire constituent member 70 are more Can be reliably bonded with high bonding strength.

加えて、移動手段１０（第１の移動機構２０）をビードセッターにより構成し、ビードセッターで接合手段３０を移動させることで、ビードセッターによるビード部材の保持動作（往復移動）と同時に、接合手段３０を往復移動させて接合動作も行える。このように、これら各動作を同時に実施できるため、端部７１、７２を接合するための独立した工数や時間を削減でき、タイヤ構成部材７０の製造に要するサイクルタイムを短縮できる。併せて、接合手段３０をビードセッターに設けることで、接合手段３０の保管スペースをなくすこともできる。   In addition, the moving means 10 (first moving mechanism 20) is constituted by a bead setter, and the joining means 30 is moved by the bead setter, so that the bead member holding operation (reciprocating movement) is simultaneously performed by the bead setter. The joining operation can also be performed by reciprocating 30. As described above, since these operations can be performed simultaneously, the number of independent processes and time for joining the end portions 71 and 72 can be reduced, and the cycle time required for manufacturing the tire constituent member 70 can be shortened. In addition, the storage space for the joining means 30 can be eliminated by providing the joining means 30 on the bead setter.

なお、接合手段３０は、往復時で、タイヤ構成部材７０の端部７１、７２に沿って対称に移動させるのが好ましい。このようにすると、往復時のそれぞれで、接合手段３０が端部７１、７２を接合する長さが一致して、往復時に接合手段３０から端部７１、７２に作用する力の差と、端部７１、７２が各接合方向に変位する量の差を更に低減できる。その結果、端部７１、７２の縁部７４、７６に変位や変形等が生じるのをより抑制でき、縁部７４、７６での接合や形状の精度を一層向上できる。   The joining means 30 is preferably moved symmetrically along the end portions 71 and 72 of the tire constituent member 70 during reciprocation. In this way, the length at which the joining means 30 joins the end portions 71 and 72 coincides with each other at the time of reciprocation, and the difference in force acting on the end portions 71 and 72 from the joining means 30 at the time of reciprocation The difference in the amount by which the portions 71 and 72 are displaced in the respective joining directions can be further reduced. As a result, it is possible to further suppress the occurrence of displacement or deformation in the edge portions 74 and 76 of the end portions 71 and 72, and the accuracy of joining and shape at the edge portions 74 and 76 can be further improved.

また、接合手段３０の接触開始位置Ｍ１、Ｍ２をサイドブラダ５の配置範囲に設定すると、接合手段３０に押圧されたタイヤ構成部材７０がサイドブラダ５に押し込まれて、タイヤ構成部材７０と接合手段３０の各ローラ３２、４０、５０との接触面積が大きくなる。その結果、移動を開始した接合手段３０の各ローラ３２、４０、５０にタイヤ構成部材７０が巻き付き、或いは、巻き込まれて、タイヤ構成部材７０に位置ずれや損傷が生じる虞が懸念される。同時に、サイドブラダ５の端部５Ｔを通過する接合手段３０が、端部５Ｔの段差を乗り越えるのに伴い、接合手段３０がタイヤ構成部材７０に引っ掛かるように移動して、その位置のタイヤ構成部材７０に不要な力が作用する虞もある。従って、往復時の接合手段３０は、サイドブラダ５よりも成形ドラム２の中央部ＣＬ側でタイヤ構成部材７０の端部７１、７２に接触させて移動を開始させるのが好ましい。これにより、タイヤ構成部材７０の位置ずれや損傷を抑制できるとともに、サイドブラダ５の変形等も抑制して、その寿命を長くすることもできる。   When the contact start positions M1 and M2 of the joining means 30 are set in the arrangement range of the side bladder 5, the tire constituent member 70 pressed by the joining means 30 is pushed into the side bladder 5, and the tire constituent member 70 and the joining means 30 are The contact area with each of the rollers 32, 40, 50 increases. As a result, there is a concern that the tire constituent member 70 may be wound around the rollers 32, 40, 50 of the joining means 30 that has started to move, or the tire constituent member 70 may be displaced or damaged. At the same time, as the joining means 30 passing through the end portion 5T of the side bladder 5 gets over the step of the end portion 5T, the joining means 30 moves so as to be caught by the tire constituting member 70, and the tire constituting member 70 at that position is moved. There is also a possibility that an unnecessary force may be applied. Therefore, it is preferable that the joining means 30 at the time of reciprocation is brought into contact with the end portions 71 and 72 of the tire constituent member 70 on the central portion CL side of the molding drum 2 with respect to the side bladder 5 to start movement. Thereby, while being able to suppress the position shift and damage of the tire structural member 70, the deformation | transformation etc. of the side bladder 5 can also be suppressed and the lifetime can also be lengthened.

以上、接合手段３０に一対の接合ローラ４０を前後に２組み配置した例を説明したが、接合手段３０には、一対の接合ローラ４０を１組み、又は、３組み以上設けてもよい。また、補強ローラ５０も、接合方向Ｓに２つ以上並べて配置して、連続して端部７１、７２の接合の補強を実行させてもよい。更に、この製造装置１を使用することで、平面状の支持部材やコンベヤ等、成形ドラム２以外の支持体上でも、同様にタイヤ構成部材７０を接合できる。   The example in which two pairs of the pair of joining rollers 40 are arranged on the front and rear of the joining unit 30 has been described above, but the joining unit 30 may be provided with one pair or three or more pairs of joining rollers 40. Further, two or more reinforcing rollers 50 may be arranged side by side in the joining direction S to continuously reinforce the joining of the end portions 71 and 72. Further, by using the manufacturing apparatus 1, the tire constituent member 70 can be similarly joined on a support body other than the forming drum 2, such as a flat support member or a conveyor.
