Description

この発明は、トロイダル状をしたタイヤ中間体の外側にゴムリボンを巻き付けるようにしたタイヤ製造方法および装置に関する。 The present invention relates to a tire manufacturing method and apparatus in which a rubber ribbon is wound around the outer side of a toroidal tire intermediate.

従来のタイヤ製造装置としては、例えば以下の特許文献１に記載されているようなものが知られている。
特開平８−１７４７０９号公報特開２００５−２１２１９７号公報 As a conventional tire manufacturing apparatus, for example, one described in Patent Document 1 below is known.
JP-A-8-174709 JP 2005-212197 A

前記特許文献１に記載のものは、バンドサーバから供給された幅広帯状のカーカスプライ、サイドトレッド等が周囲に巻き付けられることで、円筒状のカーカスバンドを成形するバンドドラムと、バンドドラムより前方にこれと同軸関係を保持しながら配置され、ベルトサーバから供給された幅広帯状のベルトプライ、トップトレッド等が周囲に巻き付けられることで、円筒状のベルトトレッドバンドを成形するベルトドラムと、バンドドラムより後方にこれと同軸関係を保持しながら配置され、カーカスバンドが供給されたとき、該カーカスバンドをトロイダル状に膨出変形させることができるシェーピングドラムと、バンドドラム、ベルトドラムから前記カーカスバンド、ベルトトレッドバンドをシェーピングドラムに供給し、ベルトトレッドバンドをトロイダル状に膨出変形したカーカスバンドの半径方向外側に貼り合わせてグリーンタイヤを成形する搬送手段とを備えたものである。 The thing of the said patent document 1 is the band drum which shape | molds a cylindrical carcass band, and the front from a band drum by the wide band-shaped carcass ply, the side tread, etc. which were supplied from the band server being wound around. A belt drum that forms a cylindrical belt tread band by being wound around the belt ply, the top tread, etc., which are arranged while maintaining a coaxial relationship with this, and are supplied from a belt server. The carcass band is arranged while maintaining a coaxial relationship with the rear, and when the carcass band is supplied, the carcass band can be bulged and deformed in a toroidal shape, and the carcass band and belt from the band drum and belt drum. Supply the tread band to the shaping drum and belt tread Is obtained by a conveying means for forming a green tire by bonding radially outward of the carcass band that bulges deformed into a toroidal shape to Ddobando.

しかしながら、このような製造装置によって製造されたタイヤは、特にトップトレッド、サイドトレッド等のゴム部分の精度をあまり高くすることができないため、ユニフォミティを充分な値まで高くすることが困難となっていた。このような課題を解決するため、例えば、前述の特許文献２に記載されているように、サイドトレッドをバンドドラム上ではなく、シェーピングドラム上においてトロイダル状に膨出変形したカーカスプライの軸方向両外側に、連続したゴムリボンを多数回巻き付けることで成形し、これにより、該サイドトレッドの精度を向上させることが考えられる。そして、このことはトップトレッド等の他のタイヤ構成部材においても同様である。 However, the tire manufactured by such a manufacturing apparatus cannot raise the accuracy of rubber parts such as the top tread and the side tread so much, so it has been difficult to increase the uniformity to a sufficient value. . In order to solve such a problem, for example, as described in Patent Document 2 described above, both the axial direction of the carcass ply in which the side tread bulges and deforms in a toroidal shape on the shaping drum, not on the band drum. It is conceivable to form a continuous rubber ribbon on the outside by winding it many times, thereby improving the accuracy of the side tread. This also applies to other tire components such as a top tread.

しかしながら、このような特許文献１、２を組み合わせたタイヤ製造方法・装置にあっては、サイドトレッド、トップトレッドを成形するためには、両トレッド用のゴムリボンをシェーピングドラム上のカーカスプライに対し異なった時間帯において順次多数回巻き付ける必要があるのに対し、カーカスバンド、ベルトバンドを成形するためには、カーカスプライ、ベルトプライをそれぞれバンドドラム、ベルトドラムに対し少数枚、例えば１〜４枚程度同時に巻き付けるだけでよいため、前者の成形時間は後者の成形時間よりかなり長くなってしまうのである。この結果、バンドドラム、ベルトドラムでのプライ巻き付け終了時から、シェーピングドラムでのゴムリボンの巻き付け終了時までの間、バンドドラム、ベルトドラムにおける成形作業が中断され、作業能率が著しく低下してしまうという課題があった。 However, in the tire manufacturing method and apparatus combining Patent Documents 1 and 2, in order to form the side tread and the top tread, the rubber ribbon for both treads is different from the carcass ply on the shaping drum. In order to form a carcass band and a belt band, a small number of carcass plies and belt plies, for example, about 1 to 4 are required for the band drum and belt drum, respectively. Since it is only necessary to wind them simultaneously, the former molding time is considerably longer than the latter molding time. As a result, from the end of ply winding on the band drum and belt drum to the end of winding of the rubber ribbon on the shaping drum, the molding operation on the band drum and belt drum is interrupted, and the work efficiency is significantly reduced. There was a problem.

You may make it move alternately between A and B and the 1st, 2nd separation station C and D. FIG. In this case, the guide rail and the driving mechanism are moving means.

前記第１成形ステーションＡにおける第１成形ドラム11の一側方には第１成形ドラム11の軸線と直交する方向に延びる第１供給手段31が設置され、この第１供給手段31は第１成形ドラム11の１周長と実質上等長で幅広帯状である少なくともカーカスプライ32を、その他インナーライナー、チェーファー、クッションゴム等を、第１成形ステーションＡにおいて回転している第１成形ドラム11に供給する。 A first supply means 31 extending in a direction perpendicular to the axis of the first forming drum 11 is installed on one side of the first forming drum 11 in the first forming station A. The first supply means 31 is a first forming means. At least the carcass ply 32 that is substantially the same length as the circumference of the drum 11 and has a wide band shape, and other inner liners, chafers, cushion rubber, and the like are rotated on the first molding drum 11 rotating at the first molding station A.

この結果、前記第１成形ステーションＡにおける第１成形ドラム11の周囲には、供給された少なくとも１枚のカーカスプライ32等が巻き付けられ、円筒状をした第１バンド13が第１成形ドラム11により成形される。また、この成形後の第１バンド13に対しては、第１成形ドラム11が第１成形ステーションＡに位置しているとき、図示していないビード供給手段から一対のフィラー付きビードが供給され、該第１バンド13の外側の所定位置にそれぞれセットされる。 As a result, around the first molding drum 11 in the first molding station A, at least one supplied carcass ply 32 or the like is wound, and the cylindrical first band 13 is formed by the first molding drum 11. Molded. Further, when the first molding drum 11 is located at the first molding station A, a pair of beads with filler is supplied from a bead supply means (not shown) to the first band 13 after molding. Each is set at a predetermined position outside the first band 13.

一方、前記第２成形ステーションＢにおける第２成形ドラム14の一側方には第２成形ドラム14の軸線と直交する方向に延びる第２供給手段34が設置され、この第２供給手段34は第２成形ドラム14の１周長と実質上等長で幅広帯状である少なくともベルトプライ35を、その他クッションゴム等を、第２成形ステーションＢにおいて回転している第２成形ドラム14に供給する。この結果、前記第２成形ステーションＢにおける第２成形ドラム14の周囲には、供給された２枚以上のベルトプライ35等が次々と巻き付けられ、円筒状をした第２バンド16が第２成形ドラム14により成形される。 On the other hand, on one side of the second molding drum 14 in the second molding station B, a second supply means 34 extending in a direction perpendicular to the axis of the second molding drum 14 is installed. 2. At least the belt ply 35 that is substantially equal in length to one circumference of the molding drum 14 and has a wide band shape, and other cushion rubber or the like are supplied to the second molding drum 14 rotating in the second molding station B. As a result, around the second molding drum 14 in the second molding station B, two or more belt plies 35 and the like supplied are wound one after another, and the cylindrical second band 16 becomes the second molding drum. 14 molded.

また、前記第２離隔ステーションＤにおける第２成形ドラム14の他側方にはリボン状体供給手段37が設置され、このリボン状体供給手段37は、他側に向かって凸状に湾曲した一対の弧状ガイドレール38が上面に敷設された固定台39と、これらガイドレール38に沿って移動可能で連続したゴムからなるリボン状体40を押出す押出し機41と、前記押出し機41をガイドレール38に沿って移動させる図示していない移動機構とから構成されている。 Further, a ribbon-shaped body supply means 37 is installed on the other side of the second forming drum 14 in the second separation station D, and the ribbon-shaped body supply means 37 is a pair of convexly curved toward the other side. The arcuate guide rail 38 is fixed on the upper surface 39, an extruder 41 for extruding a ribbon-like body 40 made of continuous rubber that is movable along the guide rail 38, and the extruder 41 is guided by the guide rail. And a moving mechanism (not shown) that moves along the line 38.

そして、前述のように第２成形ステーションＢに位置している第２成形ドラム14の周囲にベルトプライ35等が巻き付けられているとき、この押出し機41からリボン状体40が押出されるとともに、第２離隔ステーションＤに位置している第２成形ドラム14に供給されが、このとき、押出し機41は移動機構によりガイドレール38に沿って移動される。 As described above, when the belt ply 35 or the like is wound around the second forming drum 14 located at the second forming station B, the ribbon-like body 40 is extruded from the extruder 41, and While being supplied to the second forming drum 14 positioned at the second separation station D, the extruder 41 is moved along the guide rail 38 by the moving mechanism.

この結果、第２成形ドラム14に成形された第２バンド16の外側に、押出し機41から押出されたリボン状体40が多数回螺旋状に巻き付けられ、トレッドの一部、ここではベースゴムが成形される。なお、前記リボン状体40の巻き付けにより、トレッドアンダークッションをベースゴムに先立って成形するようにしてもよい。このように第２成形ドラム14を２台設け、第２離隔ステーションＤにおける第２成形ドラム14（第２バンド16）の周囲にリボン状体40を巻き付けるようにすれば、後述の第３成形ドラムの台数を増やして全体構造を複雑化することなく、第１、第２ドラム11、14における成形時間と第３成形ドラムにおける巻き付け（成形）時間との差を減少させることができる。 As a result, the ribbon-like body 40 extruded from the extruder 41 is spirally wound around the outside of the second band 16 formed on the second molding drum 14, and a part of the tread, here the base rubber, is wound. Molded. The tread undercushion may be formed prior to the base rubber by winding the ribbon-like body 40. If two second forming drums 14 are provided in this way and the ribbon-like body 40 is wound around the second forming drum 14 (second band 16) in the second separation station D, a third forming drum described later will be provided. Thus, the difference between the molding time in the first and second drums 11 and 14 and the winding (molding) time in the third molding drum can be reduced without increasing the overall structure.

また、前記第１離隔ステーションＣにおける第１成形ドラム11の他側方に前記リボン状体供給手段37と同様のリボン状体供給手段をさらに設置し、このリボン状体供給手段から供給されたリボン状体を第１離隔ステーションＣにおける第１成形ドラム11（第１バンド13）の外側に螺旋状に多数回巻き付けてベルトアンダークッションを成形するようにしてもよい。 Further, a ribbon-like body supply means similar to the ribbon-like body supply means 37 is further installed on the other side of the first forming drum 11 in the first separation station C, and the ribbon supplied from the ribbon-like body supply means. The belt undercushion may be formed by winding the shaped body spirally around the outside of the first forming drum 11 (first band 13) in the first separation station C many times.

図１、３において、44は水平な主軸45の先端側（前端側）に支持された第３成形ドラムであり、該第３成形ドラム44は、第１、第２成形ステーションＡ、Ｂにおける第１、第２成形ドラム11、14各１台に対し、２台以上、ここでは２台設けられ、これら２台の第３成形ドラム44は軸線が平行であるとともに、軸方向と直交する方向に離れている。 In FIGS. 1 and 3, reference numeral 44 denotes a third forming drum supported on the front end side (front end side) of the horizontal main shaft 45. The third forming drum 44 is the first forming station A in the first and second forming stations A and B. Two or more, two in this case, are provided for each of the first and second molding drums 11 and 14, and the two third molding drums 44 are parallel to each other in the direction perpendicular to the axial direction. is seperated.

そして、これら第３成形ドラム44は、第１成形ドラム11から第１バンド13が供給されたとき、該第１バンド13にセットされたビードを半径方向内側から把持した状態で互いに接近させるとともに、この第１バンド13内にエアを供給することで、該第１バンド13を略トロイダル状に膨出変形させることができ、さらに、前記ビードより軸方向両外側の第１バンド13を図示していない折返しブラダ等によりビード回りに折り返すことができる。 When the first band 13 is supplied from the first molding drum 11, these third molding drums 44 approach each other in a state where the beads set on the first band 13 are gripped from the radially inner side, By supplying air into the first band 13, the first band 13 can be bulged and deformed in a substantially toroidal shape, and the first band 13 on both outer sides in the axial direction from the bead is illustrated. It can be folded around the bead with no folding bladder or the like.

47は前記第３成形ドラム44より後方に設置された駆動部であり、この駆動部47と前記第３成形ドラム44との間にはアーム状の回転体48が設けられ、この回転体48に先端側（前端側）が固定された水平な回転軸49の基端側（後端側）は前記駆動部47に回転可能に支持されている。また、この回転体48の長手方向両端部には２台の第３成形ドラム44を支持する主軸45の基端部（後端部）がそれぞれ回転可能に支持されている。この結果、水平軸回りに回転可能な回転体48には周方向に等角度、ここでは 180度離れた２台の第３成形ドラム44が支持されることになる。しかも、これら第３成形ドラム44は前記第１、第２成形ドラム11、14に対向した状態で、即ち、先端同士が近接した状態で回転体48に支持されている。 Reference numeral 47 denotes a drive unit installed behind the third molding drum 44, and an arm-shaped rotary body 48 is provided between the drive unit 47 and the third molding drum 44. The base end side (rear end side) of the horizontal rotating shaft 49 to which the front end side (front end side) is fixed is rotatably supported by the drive unit 47. Further, at both ends in the longitudinal direction of the rotating body 48, the base end portions (rear end portions) of the main shaft 45 that supports the two third forming drums 44 are rotatably supported. As a result, two third forming drums 44 that are equiangular in the circumferential direction, here 180 degrees apart, are supported on the rotating body 48 that can rotate around the horizontal axis. In addition, the third molding drum 44 is supported by the rotating body 48 in a state of facing the first and second molding drums 11 and 14, that is, in a state where the tips are close to each other.

なお、前記第３成形ドラム44は２台以上であるため、例えば、図４に示すように３台、あるいは、図５に示すように４台であってもよい。そして、前者の場合には回転体48はＹ字形を呈するとともに、周方向に 120度離れた第３成形ドラム44を支持し、また、後者の場合には回転体48は十字形を呈するとともに、周方向に90度離れた第３成形ドラム44を支持することになる。 Since there are two or more third molding drums 44, there may be three as shown in FIG. 4 or four as shown in FIG. In the former case, the rotating body 48 has a Y-shape and supports the third forming drum 44 that is 120 degrees apart in the circumferential direction. In the latter case, the rotating body 48 has a cross shape, The third forming drum 44 that is 90 degrees apart in the circumferential direction is supported.

再び、図１、２において、前記駆動部47は回転体48、回転軸49を水平軸回りに、 360度を前述した第３成形ドラム44の台数で除した所定角度だけ、ここでは 180度だけ間欠的に回転させる回転体回転機構52を有し、この回転体回転機構52により回転体48、回転軸49および第３成形ドラム44が水平軸回りに間欠的に前記所定角度（ 180度）だけ回転すると、２台の第３成形ドラム44が供給ステーションＥに順次移送される。そして、前記供給ステーションＥに位置している第３成形ドラム44は、第１、第２成形ステーションＡ、Ｂにおける第１、第２成形ドラム11、14より後方で、該第１、第２成形ドラム11、14と同軸関係を保持しながら配置される。 1 and 2 again, the drive unit 47 has a rotary body 48 and a rotary shaft 49 around the horizontal axis, and 360 degrees divided by the number of the third forming drums 44 described above, here 180 degrees. A rotating body rotating mechanism 52 that rotates intermittently is provided, and the rotating body rotating mechanism 52 causes the rotating body 48, the rotating shaft 49, and the third forming drum 44 to intermittently rotate around the horizontal axis by the predetermined angle (180 degrees). When rotating, the two third forming drums 44 are sequentially transferred to the supply station E. The third molding drum 44 located at the supply station E is located behind the first and second molding drums 11 and 14 in the first and second molding stations A and B, and the first and second molding drums. The drums 11 and 14 are arranged while maintaining a coaxial relationship.

前述した回転体48、回転体回転機構52は全体として、２台以上の第３成形ドラム44を供給ステーションＥに順次供給する移送手段53を構成する。このように移送手段53を回転体48、回転体回転機構52から構成すれば、移送手段53の構造が簡単となり、製作費を安価とすることもできる。なお、いずれかの第３成形ドラム44が供給ステーションＥに位置しているとき、他の第３成形ドラム44は前記供給ステーションＥから前記所定角度の整数倍だけ、例えば第３成形ドラム44が２台のときは 180度だけ、３台のときは 120度、 240度だけ、４台のときは90度、 180度、 270度だけ離れた貼付けステーションＦにそれぞれ位置している。 The rotating body 48 and the rotating body rotating mechanism 52 described above constitute transfer means 53 that sequentially supplies two or more third forming drums 44 to the supply station E in sequence. If the transfer means 53 is composed of the rotator 48 and the rotator rotation mechanism 52 in this way, the structure of the transfer means 53 becomes simple, and the production cost can be reduced. When any of the third forming drums 44 is located at the supply station E, the other third forming drums 44 are shifted from the supply station E by an integral multiple of the predetermined angle, for example, the third forming drum 44 is 2 When it is a stand, it is located only at 180 degrees, when it is three, it is 120 degrees, only 240 degrees, and when it is four, it is located at the pasting station F, which is 90 degrees, 180 degrees and 270 degrees apart.

また、この実施形態では第３成形ドラム44を水平軸回りに回転させて供給ステーションＥに順次移送するようにしたが、２台以上の第３成形ドラム44を１つのスライド台上に載置し、該スライド台を水平面内で軸線と直交する方向に横スライドさせることで第３成形ドラム44を供給ステーションＥに順次移送するようにしてもよい。なお、このときには後述のゴムリボン供給手段もスライド台上に載置する。 In this embodiment, the third forming drum 44 is rotated about the horizontal axis and sequentially transferred to the supply station E. However, two or more third forming drums 44 are placed on one slide base. The third forming drum 44 may be sequentially transferred to the supply station E by horizontally sliding the slide table in a direction perpendicular to the axis within the horizontal plane. At this time, a rubber ribbon supply means described later is also placed on the slide table.

また、前記駆動部47は一方の第３成形ドラム44および他方の第３成形ドラム44に対しそれぞれ、回転力、ビードを半径方向内側から把持するための拡縮力、および、これらビードを接近離隔させる接離力を付与する駆動機構54、55を有し、これら駆動機構54、55からの回転力、拡縮力、接離力は図示していない伝達機構を介して第３成形ドラム44に伝達され、各第３成形ドラム44をそれぞれ個別に回転、拡縮、接離させる。 Further, the drive unit 47 moves the rotating force, the expansion / contraction force for gripping the bead from the inside in the radial direction, and the bead close to and away from the third molding drum 44 and the third molding drum 44, respectively. Drive mechanisms 54 and 55 for applying contact / separation force are provided, and rotational force, expansion / contraction force, and contact / separation force from these drive mechanisms 54 and 55 are transmitted to the third forming drum 44 via a transmission mechanism (not shown). The third forming drums 44 are individually rotated, expanded, contracted, and separated from each other.

56は第１、第２成形ステーションＡ、Ｂにおける第１、第２成形ドラム11、14の直下から供給ステーションＥにおける第３成形ドラム44の直下まで敷設され、これら第１、第２、第３成形ドラム11、14、44の軸線に平行に延びる一対のガイドレールであり、これらのガイドレール56には図示していないスライド台が摺動可能に支持され、該スライド台には同軸である２台の把持機構57、58が垂直軸回りに一括して 180度だけ回転できるよう支持されている。 56 is laid from directly under the first and second molding drums 11 and 14 at the first and second molding stations A and B to immediately below the third molding drum 44 at the supply station E. These first, second and third A pair of guide rails extending in parallel to the axis of the forming drums 11, 14, and 44, a slide base (not shown) is slidably supported by these guide rails 56, and is coaxial with the slide base. The table gripping mechanisms 57 and 58 are supported so that they can rotate by 180 degrees all around the vertical axis.

ここで、前記把持機構57は第１成形ステーションＡにおける第１成形ドラム11上に成形された第１バンド13およびフィラー付きビードを、一方、把持機構58は第２成形ステーションＢにおける第２成形ドラム14上に成形されるとともに、外側にリボン状体40が巻き付けられた第２バンド16をそれぞれ、吸着パッド、磁石等を用いることで外側から把持することができる。 Here, the gripping mechanism 57 is the first band 13 and the bead with filler formed on the first molding drum 11 in the first molding station A, while the gripping mechanism 58 is the second molding drum in the second molding station B. Each of the second bands 16 formed on the outer periphery 14 and having the ribbon-like body 40 wound around it can be gripped from the outside by using a suction pad, a magnet, or the like.

そして、これら把持機構57、58は前記第１、第２バンド13、16を外側から把持した後、第１、第２成形ドラム11、14が縮径することで、これら第１、第２成形ドラム11、14から第１、第２バンド13、16を取り出すが、このようにして第１、第２成形ドラム11、14から取り出された第１、第２バンド13、16は、図示していないシリンダ、ねじ機構等によりガイドレール56に沿って把持機構57、58が後方に移動することで、供給ステーションＥに位置している第３成形ドラム44に供給される。 These gripping mechanisms 57 and 58 grip the first and second bands 13 and 16 from the outside, and then the first and second molding drums 11 and 14 are reduced in diameter so that the first and second moldings are performed. The first and second bands 13 and 16 are taken out from the drums 11 and 14, and the first and second bands 13 and 16 thus taken out from the first and second forming drums 11 and 14 are shown in the drawing. The gripping mechanisms 57 and 58 are moved rearward along the guide rail 56 by a non-cylinder, a screw mechanism, and the like, so that the third forming drum 44 located at the supply station E is supplied.

ここで、前記供給ステーションＥの第３成形ドラム44においては、前述したように第１バンド13がトロイダル状に膨出変形している途中に、把持機構58によって搬送された第２バンド16が該第１バンド13の半径方向外側に貼り合わされる。前述したスライド台、把持機構57、58は全体として、第１、第２成形ステーションＡ、Ｂにおける第１、第２成形ドラム11、14から前記第１、第２バンド13、16を供給ステーションＥにおける第３成形ドラム44に供給し、トロイダル状に膨出変形した第１バンド13の半径方向外側に第２バンド16を貼り合わせてタイヤ中間体59を成形することができる搬送手段60を構成する。 Here, in the third forming drum 44 of the supply station E, the second band 16 conveyed by the gripping mechanism 58 is in the middle of the first band 13 bulging and deforming in a toroidal shape as described above. The first band 13 is bonded to the outside in the radial direction. The above-described slide table and gripping mechanisms 57 and 58 as a whole supply the first and second bands 13 and 16 from the first and second molding drums 11 and 14 in the first and second molding stations A and B to the supply station E. To the third forming drum 44 in the above, and the second band 16 is bonded to the outer side in the radial direction of the first band 13 bulging and deformed in a toroidal shape to form the tire intermediate body 59. .

なお、この実施形態においては、搬送手段60によって第１、第２バンド13、16を供給ステーションＥにおける第３成形ドラム44に供給するようにしたが、この発明においては、いずれのステーションＥ、Ｆに位置しているかに関わりなく、２台以上の第３成形ドラム44、詳しくは成形済みのグリーンタイヤが取り出され空となった第３成形ドラム44に対して搬送手段により第１、第２成形ドラム11、14から第１、第２バンド13、16を順次供給するようにしてもよい。但し、このようにした場合には、搬送手段の移動経路が複雑となり、この結果、全体の構造が複雑となって作業能率が若干低下する。 In this embodiment, the first and second bands 13 and 16 are supplied to the third forming drum 44 in the supply station E by the conveying means 60. In the present invention, any of the stations E and F is supplied. Regardless of whether or not they are positioned, the first and second molding drums 44 are transported by two or more third molding drums 44, specifically, the third molding drum 44 in which the molded green tire is removed and emptied. The first and second bands 13 and 16 may be sequentially supplied from the drums 11 and 14. However, in this case, the movement path of the conveying means becomes complicated, and as a result, the overall structure becomes complicated and the work efficiency is slightly lowered.

これに対し、この実施形態のように移送手段53によって第３成形ドラム44を供給ステーションＥに順次移送し、この供給ステーションＥにおける第３成形ドラム44に対し第１、第２バンド13、16を供給するようにすれば、搬送手段60による第１、第２バンド13、16の供給先を供給ステーションＥ（第３成形ドラム44）に固定することができるため、搬送手段60の移動経路を単純化することができ、これにより、構造が簡単となり作業能率も向上させることができる。 On the other hand, the third forming drum 44 is sequentially transferred to the supply station E by the transfer means 53 as in this embodiment, and the first and second bands 13 and 16 are attached to the third forming drum 44 in the supply station E. If it is made to supply, since the supply destination of the 1st, 2nd bands 13 and 16 by the conveyance means 60 can be fixed to the supply station E (3rd shaping | molding drum 44), the movement path | route of the conveyance means 60 is simple. As a result, the structure becomes simple and the work efficiency can be improved.

さらに、前述のように第２成形ステーションＢにおける第２成形ドラム14を第１成形ステーションＡにおける第１成形ドラム11より前方に、また、供給ステーションＥにおける第３成形ドラム44を前記第１、第２成形ドラム11、14より後方に配置するとともに、これら３つのドラム11、14、44を同軸関係を保持しながら配置し、搬送手段60を前記ドラム11、14、44の軸線に沿って移動させることで、第１、第２バンド13、16を前記各ステーションにおける第１、第２成形ドラム11、14から第３成形ドラム44に供給するようにすれば、搬送手段60の移動経路をドラムの軸線に沿った直線状にまで単純化することができ、これにより、全体構造がさらに簡単となり作業能率もさらに向上する。 Further, as described above, the second molding drum 14 in the second molding station B is placed in front of the first molding drum 11 in the first molding station A, and the third molding drum 44 in the supply station E is disposed in the first and second molding drums. 2 Arranged behind the forming drums 11 and 14, these three drums 11, 14 and 44 are arranged while maintaining a coaxial relationship, and the conveying means 60 is moved along the axis of the drums 11, 14 and 44. Thus, if the first and second bands 13 and 16 are supplied from the first and second molding drums 11 and 14 to the third molding drum 44 in each of the stations, the movement path of the conveying means 60 can be changed. It can be simplified to a straight line along the axis, which further simplifies the overall structure and further improves work efficiency.

前記供給ステーションＥにおける第３成形ドラム44の他側方には第１ゴムリボン供給手段63が設置され、この第１ゴムリボン供給手段63はベース64と、ベース64上に敷設され、第３成形ドラム44の軸方向中央を通過し、かつ、該第３成形ドラム44の軸線と直交する水平線の両側（前後）にそれぞれ配置されるとともに、前方および後方に凸状に湾曲した一対のガイドレール65と、図示していない駆動機構から駆動力を受けることにより、ガイドレール65に沿って移動する一対のスライドプレート66と、各スライドプレート66上に垂直軸回りに回動できるよう支持され、連続したゴムリボン67を押出すことができる押出し機68とから構成されている。 On the other side of the third forming drum 44 in the supply station E, a first rubber ribbon supply means 63 is installed. The first rubber ribbon supply means 63 is laid on the base 64 and the base 64, and the third forming drum 44 is provided. A pair of guide rails 65 that are respectively disposed on both sides (front and rear) of a horizontal line that passes through the center in the axial direction of the third forming drum 44 and that is orthogonal to the axis of the third forming drum 44 and that curves convexly forward and backward, By receiving a driving force from a driving mechanism (not shown), a pair of slide plates 66 moving along the guide rails 65 are supported on each slide plate 66 so as to be rotatable about a vertical axis, and a continuous rubber ribbon 67 is provided. And an extruder 68 that can extrude.

そして、供給ステーションＥにおける第３成形ドラム44が駆動機構54からの回転力を受けて回転しているとき、押出し機68から押出された連続しているゴムリボン67を第３成形ドラム44、詳しくはタイヤ中間体59の軸方向両外側にそれぞれ供給するとともに、前記押出し機68を駆動機構によりガイドレール65に沿って移動させながら垂直軸回りに回動させると、タイヤ中間体59の軸方向両外側にはゴムリボン67が渦巻き状に多数回巻き付けられ、サイドトレッドが、場合によってはゴムチェーファーも成形される。 When the third molding drum 44 in the supply station E is rotated by receiving the rotational force from the drive mechanism 54, the continuous rubber ribbon 67 extruded from the extruder 68 is transferred to the third molding drum 44. When the extruder 68 is rotated around the vertical axis while being moved along the guide rail 65 by the drive mechanism while being supplied to both axial outer sides of the tire intermediate 59, both axial outer sides of the tire intermediate 59 are obtained. A rubber ribbon 67 is wound many times in a spiral shape to form a side tread and, in some cases, a rubber chafer.

前記貼付けステーションＦにおける第３成形ドラム44の一側方には第２ゴムリボン供給手段70が設置され、この第２ゴムリボン供給手段70は、ベース71と、ベース71上に敷設され、前記第３成形ドラム44に装着されているタイヤ中間体59のトレッド部の曲率中心近傍に曲率中心が位置している一対のガイドレール72と、図示していない駆動機構から駆動力を受けることにより、ガイドレール72に沿って移動するスライドプレート73と、該スライドプレート73上に設置され連続したゴムリボン74を押出す押出し機75とから構成されている。 A second rubber ribbon supply means 70 is installed on one side of the third forming drum 44 in the affixing station F. The second rubber ribbon supply means 70 is laid on the base 71 and the base 71, and the third forming By receiving a driving force from a pair of guide rails 72 in which the center of curvature is located in the vicinity of the center of curvature of the tread portion of the tire intermediate 59 attached to the drum 44 and a driving mechanism (not shown), the guide rail 72 , And an extruder 75 for extruding a continuous rubber ribbon 74 installed on the slide plate 73.

そして、貼付けステーションＦにおける第３成形ドラム44が駆動機構54から回転力を受けて回転しているとき、押出し機75から押出された連続しているゴムリボン74を第３成形ドラム44、詳しくはタイヤ中間体59の半径方向外側に供給するとともに、前記スライドプレート73、押出し機75を駆動機構によりガイドレール72に沿って移動させると、タイヤ中間体59の半径方向外側にはゴムリボン74が螺旋状に多数回巻き付けられ、トレッドの一部、ここではキャップゴムが成形され、これにより、グリーンタイヤが成形される。 When the third molding drum 44 in the pasting station F is rotated by receiving the rotational force from the drive mechanism 54, the continuous rubber ribbon 74 extruded from the extruder 75 is transferred to the third molding drum 44, specifically the tire. When the slide plate 73 and the extruder 75 are moved along the guide rail 72 by the drive mechanism while being fed to the outer side in the radial direction of the intermediate body 59, a rubber ribbon 74 spirals on the outer side in the radial direction of the tire intermediate body 59. It is wound many times to form a part of the tread, here a cap rubber, thereby forming a green tire.

ここで、前述した供給ステーションＥの第３成形ドラム44（タイヤ中間体59）におけるゴムリボン67の巻き付け、および、貼付けステーションＦの第３成形ドラム44（タイヤ中間体59）におけるゴムリボン74の巻き付けは同時に行われる。ここで、同時とは、ゴムリボン67およびゴムリボン74の巻き付け開始時と巻き付け終了時とが完全に同一時点である必要はなく、異なっていてもよい。但し、異なっているときは、巻き付け時間が長い方の開始時から終了時までの間に、巻き付け時間が短い方の開始および終了の双方が行われる必要がある。 Here, the winding of the rubber ribbon 67 on the third molding drum 44 (tire intermediate body 59) of the supply station E and the winding of the rubber ribbon 74 on the third molding drum 44 (tire intermediate body 59) of the pasting station F are simultaneously performed. Done. Here, “simultaneous” does not require that the start of winding of the rubber ribbon 67 and the rubber ribbon 74 and the end of winding be completely the same time, and they may be different. However, if they are different, both the start and end of the shorter winding time need to be performed from the start to the end of the longer winding time.

このように２台の第３成形ドラム44に対して搬送手段60により第１、第２バンド13、16を順次供給する一方、いずれの第３成形ドラム44においても同時にゴムリボン67、74をタイヤ中間体59に巻き付けるようにすれば、従来の１台のシェーピングドラムにおけるゴムリボンの巻き付けが、２台以上の第３成形ドラム44におけるゴムリボンの巻き付けに分散され、第１、第２成形ドラム11、14における成形時間と各第３成形ドラム44における成形（巻き付け）時間との差が減少して、第１、第２成形ドラム11、14または第３成形ドラム44における成形作業の中断時間が短縮され、これにより、作業能率を効果的に向上させることができる。 As described above, the first and second bands 13 and 16 are sequentially supplied to the two third molding drums 44 by the conveying means 60, and the rubber ribbons 67 and 74 are simultaneously attached to the middle of the tire in any third molding drum 44. If it is wound around the body 59, the winding of the rubber ribbon in one conventional shaping drum is dispersed into the winding of the rubber ribbon in two or more third forming drums 44, and in the first and second forming drums 11 and 14 The difference between the molding time and the molding (winding) time in each third molding drum 44 is reduced, and the interruption time of the molding operation in the first, second molding drum 11, 14 or the third molding drum 44 is shortened. Thus, the work efficiency can be effectively improved.

また、図４または５に示すように、第３成形ドラム44を３台または４台設置した場合には、供給ステーションＥ以外に貼付けステーションＦがそれぞれ２箇所または３箇所存在することになるが、これら２箇所または３箇所の貼付けステーションＦにおける第３成形ドラム44に対しても、供給ステーションＥの第３成形ドラム44に対するゴムリボン67の巻き付けと同時に、ゴムリボンの巻き付けを行うようにすれば、第１、第２成形ドラム11、14における成形時間がかなり短くても、該第１、第２成形ドラム11、14における成形時間と各第３成形ドラム44における成形（巻き付け）時間との差を効果的に減少させることができる。 Moreover, as shown in FIG. 4 or 5, when three or four third forming drums 44 are installed, there are two or three application stations F in addition to the supply station E, If the rubber ribbon 67 is wound around the third forming drum 44 at the two or three attaching stations F at the same time as the rubber ribbon 67 is wound around the third forming drum 44 at the supply station E, the first forming drum 44 will be described. Even if the molding time in the second molding drums 11 and 14 is considerably short, the difference between the molding time in the first and second molding drums 11 and 14 and the molding (winding) time in each third molding drum 44 is effective. Can be reduced.

さらに、この実施形態では、２台以上の第３成形ドラム44に対して、別個のゴムリボン供給手段からゴムリボンをそれぞれ供給するようにしているため、ゴムリボン供給手段が広範囲に分散配置され、ゴムリボンの供給等が容易となる。さらに、前述した供給ステーションＥ、貼付けステーションＦのタイヤ中間体59に対するゴムリボン67、74の巻き付けは容易に自動運転とすることができるが、第１、第２成形ステーションＡ、Ｂの第１、第２成形ドラム11、14に対するカーカスプライ32、ベルトプライ35の巻き付けは作業員Ｍが監視をする必要があるので、これら第１、第２成形ドラム11、14を前方側に集合させて作業員Ｍによる監視を容易としている。 Furthermore, in this embodiment, since the rubber ribbon is supplied from the separate rubber ribbon supply means to the two or more third molding drums 44, the rubber ribbon supply means is widely distributed and supplied. Etc. becomes easy. Further, the winding of the rubber ribbons 67 and 74 around the tire intermediate body 59 of the supply station E and the pasting station F described above can be easily performed automatically, but the first and second molding stations A and B can be automatically operated. Since it is necessary for the worker M to monitor the winding of the carcass ply 32 and the belt ply 35 around the two forming drums 11 and 14, the first and second forming drums 11 and 14 are gathered to the front side and the worker M Monitoring is easy.

次に、前記実施形態１の作用について説明する。
前述のようなタイヤ製造装置を用いてグリーンタイヤを製造する場合には、各ドラム、各手段が同時に作動しているので、一括して説明を行うと、説明が複雑となり、理解が困難となる。このため、この実施形態では、単一のカーカスプライに着目して作用を説明する。 Next, the operation of the first embodiment will be described.
When manufacturing a green tire using the tire manufacturing apparatus as described above, since each drum and each means are operating at the same time, the description will be complicated and difficult to understand if explained collectively. . For this reason, in this embodiment, the operation will be described focusing on a single carcass ply.

今、空である拡径状態の第１、第２成形ドラム11、14が第１、第２成形ステーションＡ、Ｂに位置しているとする。次に、回転拡縮機構27により第１、第２成形ドラム11、14を軸線回りに回転させるとともに、第１供給手段31から少なくともカーカスプライ32を第１成形ステーションＡにおける第１成形ドラム11に、第２供給手段34から少なくともベルトプライ35を第２成形ステーションＢにおける第２成形ドラム14にそれぞれ供給する。この結果、これらカーカスプライ32およびベルトプライ35は第１、第２成形ドラム11、14の周囲に巻き付けられるとともに、その始、終端同士が接合され、円筒状の第１、第２バンド13、16がそれぞれ成形される。 Assume that the first and second molding drums 11 and 14 that are empty and have an enlarged diameter are positioned at the first and second molding stations A and B. Next, the rotary expansion / contraction mechanism 27 rotates the first and second molding drums 11 and 14 around the axis, and at least the carcass ply 32 from the first supply means 31 is transferred to the first molding drum 11 in the first molding station A. At least the belt ply 35 is supplied from the second supply means 34 to the second forming drum 14 in the second forming station B. As a result, the carcass ply 32 and the belt ply 35 are wound around the first and second forming drums 11 and 14, and the start and end thereof are joined together, so that the cylindrical first and second bands 13, 16 are joined. Are molded respectively.

次に、回転部材回転機構24により回転部材20、回転軸21および第１、第２成形ドラム11、14を水平軸回りに 180度だけ回転させ、第１、第２成形ステーションＡ、Ｂに位置していた第１、第２成形ドラム11、14を第１、第２離隔ステーションＣ、Ｄまでそれぞれ移動させる。次に、回転拡縮機構27により第２成形ドラム14を軸線回りに回転させるが、このとき、押出し機41から押出されたリボン状体40を第２離隔ステーションＤに位置している第２成形ドラム14に供給するとともに、押出し機41をガイドレール38に沿って移動させる。この結果、該第２成形ドラム14（第２バンド16）の外側には押出し機41から押出されたリボン状体40が多数回螺旋状に巻き付けられ、トレッドの一部、ここではベースゴムが成形される。 Next, the rotating member rotating mechanism 24 rotates the rotating member 20, the rotating shaft 21, and the first and second forming drums 11 and 14 by 180 degrees around the horizontal axis, and is positioned at the first and second forming stations A and B. The first and second forming drums 11 and 14 that have been moved are moved to the first and second separation stations C and D, respectively. Next, the second forming drum 14 is rotated about the axis by the rotation expansion / contraction mechanism 27. At this time, the ribbon-like body 40 extruded from the extruder 41 is located at the second separation station D. 14 and the extruder 41 is moved along the guide rail 38. As a result, the ribbon-like body 40 extruded from the extruder 41 is wound many times around the outside of the second molding drum 14 (second band 16), and a part of the tread, here, the base rubber is molded. Is done.

なお、このように第２離隔ステーションＤにおける第２成形ドラム14（第２バンド16）にリボン状体40を巻き付けているとき、第１、第２成形ステーションＡ、Ｂに位置している空の第１、第２成形ドラム11、14にも前述と同様にカーカスプライ32、ベルトプライ35をそれぞれ巻き付ける。次に、回転部材回転機構24により回転部材20および第１、第２成形ドラム11、14を水平軸回りに 180度だけ回転させ、第１、第２離隔ステーションＣ、Ｄに位置していた第１、第２成形ドラム11、14を第１、第２成形ステーションＡ、Ｂに復帰させる。 In addition, when the ribbon-like body 40 is wound around the second forming drum 14 (second band 16) in the second separation station D in this way, empty spaces located at the first and second forming stations A and B are used. The carcass ply 32 and the belt ply 35 are wound around the first and second forming drums 11 and 14 as described above. Next, the rotating member 20 and the first and second forming drums 11 and 14 are rotated by 180 degrees around the horizontal axis by the rotating member rotating mechanism 24, and the first and second separation stations C and D are located at the first positions. 1. Return the second molding drums 11 and 14 to the first and second molding stations A and B.

次に、第１成形ステーションＡにおける第１成形ドラム11（第１バンド13）の外側に一対のフィラー付きビードを供給して所定位置にそれぞれセットした後、スライド台および把持機構57、58をガイドレール56に沿って前方に、これら把持機構57、58が第１、第２成形ステーションＡ、Ｂにおける第１、第２成形ドラム11、14を外側から囲む位置まで、移動させる。次に、搬送手段60を構成する把持機構57および把持機構58によりビード、第１バンド13および第２バンド16をそれぞれ把持した後、前記第１、第２成形ドラム11、14を縮径させ、第１、第２成形ステーションＡ、Ｂにおける第１、第２成形ドラム11、14から第１、第２バンド13、16を把持機構57、58にそれぞれ移載する。 Next, after a pair of beads with filler is supplied to the outside of the first molding drum 11 (first band 13) in the first molding station A and set at predetermined positions, the slide table and the gripping mechanisms 57 and 58 are guided. These gripping mechanisms 57 and 58 move forward along the rail 56 to a position surrounding the first and second molding drums 11 and 14 at the first and second molding stations A and B from the outside. Next, after gripping the bead, the first band 13 and the second band 16 by the gripping mechanism 57 and the gripping mechanism 58 constituting the conveying means 60, respectively, the first and second molding drums 11 and 14 are reduced in diameter, The first and second bands 13 and 16 are transferred from the first and second molding drums 11 and 14 in the first and second molding stations A and B to the gripping mechanisms 57 and 58, respectively.

次に、把持機構57、58をガイドレール56に沿って後方に、該把持機構57に把持されている第１バンド13が供給ステーションＥにおける第３成形ドラム44を外側から囲む位置まで、移動させる。この結果、第１、第２成形ステーションＡ、Ｂの第１、第２成形ドラム11、14は空となる。次に、駆動機構54が作動して第３成形ドラム44が第１バンド13にセットされたビードを半径方向内側から把持すると、把持機構57は前記第１バンド13を把持から解放し、これにより、該第１バンド13は把持機構57から供給ステーションＥにおける第３成形ドラム44に供給される。次に、把持機構57、58はガイドレール56に沿って前方に移動し、供給ステーションＥにおける第３成形ドラム44から離脱するとともに、垂直軸回りに 180度回転する。 Next, the gripping mechanisms 57 and 58 are moved rearward along the guide rail 56 to a position where the first band 13 gripped by the gripping mechanism 57 surrounds the third forming drum 44 in the supply station E from the outside. . As a result, the first and second molding drums 11 and 14 of the first and second molding stations A and B are empty. Next, when the driving mechanism 54 is operated and the third molding drum 44 grips the bead set on the first band 13 from the radially inner side, the gripping mechanism 57 releases the first band 13 from the grip, thereby The first band 13 is supplied from the gripping mechanism 57 to the third forming drum 44 in the supply station E. Next, the gripping mechanisms 57 and 58 move forward along the guide rail 56, detach from the third forming drum 44 in the supply station E, and rotate 180 degrees around the vertical axis.

その後、前記第３成形ドラム44において、一対のビードが互いに接近されるとともに、第１バンド13内にエアが供給されることで、該第１バンド13が略トロイダル状に膨出変形するが、このとき、ビードより軸方向両外側の第１バンド13が折返しブラダによりビード回りに折り返される。そして、前述のような膨出変形の途中において、把持機構57、58を後方に向かって移動させ、膨出変形した第１バンド13の外側に把持機構58に支持されている第２バンド16を嵌合する。この状態で第１バンド13をさらに略トロイダル状に近付くよう膨出変形させると、第２バンド16は第１バンド13の半径方向外側に貼り合わされて第２ドラム44に供給され、タイヤ中間体59が成形される。その後、把持機構57、58は前方に向かって第１成形ドラム11と第３成形ドラム44との間の待機位置まで移動するとともに、該待機位置において垂直軸回りに 180度回転する。 Thereafter, in the third forming drum 44, the pair of beads are brought close to each other and air is supplied into the first band 13, whereby the first band 13 bulges and deforms in a substantially toroidal shape. At this time, the first band 13 on both outer sides in the axial direction from the bead is folded around the bead by the folding bladder. In the middle of the bulging deformation as described above, the gripping mechanisms 57 and 58 are moved rearward, and the second band 16 supported by the gripping mechanism 58 is placed outside the bulging and deformed first band 13. Mating. In this state, when the first band 13 is further bulged and deformed so as to approach a toroidal shape, the second band 16 is bonded to the outer side in the radial direction of the first band 13 and supplied to the second drum 44, so that the tire intermediate 59 Is formed. Thereafter, the gripping mechanisms 57, 58 move forward to a standby position between the first molding drum 11 and the third molding drum 44, and rotate 180 degrees around the vertical axis at the standby position.

次に、スライドプレート66、押出し機68がガイドレール65に沿って供給ステーションＥにおける第３成形ドラム44に接近し巻き付け位置に到達すると、駆動機構54により供給ステーションＥにおける第３成形ドラム44、タイヤ中間体59を回転させる。このとき、タイヤ中間体59の前後に位置する一対の押出し機68（第１ゴムリボン供給手段63）からの連続したゴムリボン67は前記第３成形ドラム44、詳しくはタイヤ中間体59の軸方向外側にそれぞれ供給され、一方、押出し機68がガイドレール65に沿って移動しながら垂直軸回りに回動するため、タイヤ中間体59の軸方向両外側にはゴムリボン67が渦巻き状に多数回巻き付けられ、サイドトレッドが成形される。その後、スライドプレート66、押出し機68がガイドレール65に沿って第３成形ドラム44から離隔する。 Next, when the slide plate 66 and the extruder 68 approach the third forming drum 44 in the supply station E along the guide rail 65 and reach the winding position, the drive mechanism 54 causes the third forming drum 44 and tire in the supply station E to reach the winding position. The intermediate body 59 is rotated. At this time, the continuous rubber ribbon 67 from the pair of extruders 68 (first rubber ribbon supply means 63) located in front of and behind the tire intermediate body 59 is disposed outside the third molding drum 44, specifically, the tire intermediate body 59 in the axial direction. On the other hand, since the extruder 68 rotates along the vertical axis while moving along the guide rail 65, the rubber ribbon 67 is wound many times in a spiral shape on both outer sides in the axial direction of the tire intermediate 59, A side tread is formed. Thereafter, the slide plate 66 and the extruder 68 are separated from the third forming drum 44 along the guide rail 65.

Next, the third forming drum 44 and the tire intermediate 59 in the pasting station F are rotated by the drive mechanism 54. At this time, the continuous rubber ribbon 74 from the extruder 75 (second rubber ribbon supply means 70) is respectively supplied to the third molding drum 44, specifically, the radially outer side of the tire intermediate body 59. When moving along the guide rail 72, a rubber ribbon 74 is spirally wound around the outer side in the radial direction of the tire intermediate 59, and a part of the tread, here a cap rubber, is formed. Is formed.

なお、このように貼付けステーションＦの第３成形ドラム44（タイヤ中間体59）にゴムリボン74を巻き付けているとき、供給ステーションＥの第３成形ドラム44（タイヤ中間体59）にも前述と同様にゴムリボン67を同時に巻き付ける。また、前述のように供給ステーションＥ、貼付けステーションＦの第３成形ドラム44（タイヤ中間体59）にゴムリボン67、74をそれぞれ巻き付けているとき、第１、第２成形ステーションＡ、Ｂ、第２離隔ステーションＤの第１、第２成形ドラム11、14（第２バンド16）にも前述と同様にカーカスプライ32、ベルトプライ35、リボン状体40をそれぞれ巻き付ける。 When the rubber ribbon 74 is wound around the third forming drum 44 (tire intermediate body 59) of the pasting station F as described above, the third forming drum 44 (tire intermediate body 59) of the supply station E is also the same as described above. Wrap the rubber ribbon 67 at the same time. Further, when the rubber ribbons 67 and 74 are wound around the third forming drum 44 (tire intermediate body 59) of the supply station E and the pasting station F as described above, the first and second forming stations A, B, and 2 The carcass ply 32, the belt ply 35, and the ribbon-like body 40 are wound around the first and second forming drums 11 and 14 (second band 16) of the separation station D in the same manner as described above.

その後、前記グリーンタイヤを貼付けステーションＦにおける第３成形ドラム44から図示していない搬出手段により取り出して加硫工程に搬出する。次に、回転体回転機構52により回転体48を 180度だけ回転させ、貼付けステーションＦの空となった第３成形ドラム44を供給ステーションＥに復帰させる。一方、前記加硫工程においては、前記グリーンタイヤが加硫装置に搬入された後、高温、高圧の加硫媒体により加硫され加硫済タイヤが製造される。 Thereafter, the green tire is taken out from the third forming drum 44 at the pasting station F by unillustrated unloading means and unloaded into the vulcanization process. Next, the rotating body 48 is rotated by 180 degrees by the rotating body rotating mechanism 52, and the third forming drum 44 emptied in the pasting station F is returned to the supply station E. On the other hand, in the vulcanization step, the green tire is carried into a vulcanizer, and then vulcanized with a high-temperature, high-pressure vulcanization medium to produce a vulcanized tire.

In this embodiment, a second molding drum 82 supported by a drive unit 80 via a main shaft 81 is disposed in front of the third molding drum 44 on the axis of the third molding drum 44 at the supply station E. A second supply means 34 for supplying the belt ply 35 to the second molding drum 82 is provided on one side of the second molding drum 82. Here, the driving unit 80, the second molding drum 82, and the second supply unit 34 receive a moving force from a moving unit (not shown) and move integrally in a direction perpendicular to the axis of the second molding drum 82. be able to.

また、前記第２成形ドラム82より前方で該第２成形ドラム82の軸線より他側方には、第２成形ドラム82の軸線に直交する軸線を有する第１成形ドラム83が設けられ、この第１成形ドラム83は主軸84を介して駆動部85に支持されている。そして、この第１成形ドラム83の前方には該第１成形ドラム83にカーカスプライ32を供給する第１供給手段31が設置されている。ここで、前記第１成形ドラム83、駆動部85は図示していない移動手段から移動力を受けて第１成形ドラム83の軸線方向に移動することができる。 A first molding drum 83 having an axis perpendicular to the axis of the second molding drum 82 is provided in front of the second molding drum 82 and on the other side of the axis of the second molding drum 82. The one molding drum 83 is supported by the drive unit 85 via the main shaft 84.

Here, the first molding drum 83 and the drive unit 85 can move in the axial direction of the first molding drum 83 by receiving a moving force from a moving means (not shown).

前記供給ステーションＥにおける第３成形ドラム44の軸線と第１成形ドラム83の軸線との交点には、第１成形ドラム83によって成形された第１バンド13を把持することができる把持機構86が設置され、この把持機構86は垂直軸回りに90度だけ回動可能であるとともに、図示していない移動手段から移動力を受けて供給ステーションＥにおける第３成形ドラム44の軸線方向に移動することができる。87は第２成形ドラム82と把持機構86との間に設置された把持機構であり、この把持機構87は第２成形ドラム82によって成形された第２バンド16を把持することができるとともに、図示していない移動手段から移動力を受けて把持機構86と同一方向に移動することができる。 At the intersection of the axis of the third molding drum 44 and the axis of the first molding drum 83 at the supply station E, a gripping mechanism 86 that can grip the first band 13 molded by the first molding drum 83 is installed. The gripping mechanism 86 can be rotated by 90 degrees around the vertical axis, and can move in the axial direction of the third forming drum 44 in the supply station E by receiving a moving force from a moving means (not shown). it can. Reference numeral 87 denotes a gripping mechanism installed between the second molding drum 82 and the gripping mechanism 86. The gripping mechanism 87 can grip the second band 16 molded by the second molding drum 82. It can move in the same direction as the gripping mechanism 86 by receiving a moving force from a moving means (not shown).

そして、このようなタイヤ製造装置を用いてグリーンタイヤを製造する場合には、回転している第１成形ドラム83に第１供給手段31からカーカスプライ32を供給して該カーカスプライ32を第１成形ドラム83の周囲に巻き付け第１バンド13を成形するとともに、回転している第２成形ドラム82に第２供給手段34からベルトプライ35を供給して該ベルトプライ35を第２成形ドラム82の周囲に巻き付け第２バンド16を成形する。次に、第１成形ドラム83、駆動部85を一側に移動させて第１成形ドラム83を把持機構86内に挿入し、第１バンド13を第１成形ドラム83から把持機構86に受け渡す。このとき、把持機構87を第２成形ドラム82の外側に嵌合されるまで後方に移動させるとともに、第２成形ドラム82から第２バンド16を把持機構87に受け渡す。 And when manufacturing a green tire using such a tire manufacturing apparatus, the carcass ply 32 is supplied to the rotating first forming drum 83 from the first supply means 31 and the carcass ply 32 is firstly connected. The first band 13 is wound around the molding drum 83 and the belt ply 35 is supplied from the second supply means 34 to the rotating second molding drum 82, and the belt ply 35 is attached to the second molding drum 82. A second band 16 is formed around the periphery. Next, the first molding drum 83 and the drive unit 85 are moved to one side to insert the first molding drum 83 into the gripping mechanism 86, and the first band 13 is transferred from the first molding drum 83 to the gripping mechanism 86. . At this time, the gripping mechanism 87 is moved backward until it is fitted to the outside of the second molding drum 82, and the second band 16 is transferred from the second molding drum 82 to the gripping mechanism 87.

その後、駆動部80、第２成形ドラム82、第２供給手段34を一体的に一側に移動させるとともに、把持機構86を垂直軸回りに90度だけ回動させて該把持機構86の軸線を把持機構87の軸線と同軸とする。次に、これら把持機構86、87を、該把持機構86が供給ステーションＥにおける第３成形ドラム44の外側に嵌合するまで後方に移動させた後、該把持機構86から第１バンド13を供給ステーションＥにおける第３成形ドラム44に移載する。次に、第３成形ドラム44は第１バンド13を略トロイダル状に膨出変形させるが、この膨出変形の途中で把持機構86は初期位置に向かって前方に移動し、一方、把持機構87は第３成形ドラム44の外側に嵌合する位置まで移動する。 Thereafter, the drive unit 80, the second forming drum 82, and the second supply means 34 are integrally moved to one side, and the gripping mechanism 86 is rotated by 90 degrees about the vertical axis so that the axis of the gripping mechanism 86 is aligned.

During the bulging deformation, the gripping mechanism 86 moves forward toward the initial position, while the gripping mechanism 87. Moves to a position where it fits outside the third forming drum 44.

この結果、把持機構87に把持されていた第２バンド16は第１バンド13の半径方向外側に貼付けられ、タイヤ中間体59が成形される。このとき、把持機構86、87は初期位置まで前方に移動する。その後、供給ステーションＥおよび貼付けステーションＦにおける２台の第３成形ドラム44（タイヤ中間体59）の周囲にゴムリボンを同時に巻き付ける。なお、他の構成、作用は前記実施形態１と同様である。そして、この実施形態のように第１バンド13を把持する把持機構86を、直線移動だけでなく90度の回動もできるようにすれば、第２成形ドラム82、第１成形ドラム83をレイアウトする際の自由度が高くなり、この実施形態とは異なるレイアウトも可能である。なお、第２バンド16を把持する把持機構87を90度回動できるようにしても、同様の効果を得ることができる。 As a result, the second band 16 held by the holding mechanism 87 is attached to the outer side in the radial direction of the first band 13, and the tire intermediate body 59 is formed. At this time, the gripping mechanisms 86 and 87 move forward to the initial position. Thereafter, a rubber ribbon is wound around the two third forming drums 44 (tire intermediate bodies 59) at the supply station E and the pasting station F at the same time. Other configurations and operations are the same as those of the first embodiment. If the gripping mechanism 86 for gripping the first band 13 can be rotated not only by linear movement but also by 90 degrees as in this embodiment, the second molding drum 82 and the first molding drum 83 are laid out. The degree of freedom is increased, and a layout different from this embodiment is possible. The same effect can be obtained even if the gripping mechanism 87 that grips the second band 16 can be rotated by 90 degrees.
