Abstract

PROBLEM TO BE SOLVED: To provide a device capable of winding a strip member 16 around an object with improved quality in winding without decreasing operation efficiency.SOLUTION: Limiting members 62, 63 are disposed between centering rollers 32a, 33a in a width direction, and lower surfaces 62a, 63a of the limiting members 62, 63 are positioned lower than upper ends of guides 34, 35 of the centering rollers 32a, 33a of centering roller 32a, 33a. Therefore, if a terminal end of a strip member 16 deforms so as to rise by an elastic restoration force, the terminal end is restrained by the limiting members 62, 63 to be lower than the upper ends of the guide 34, 35. As a result, the terminal end of the strip member 16 is continuously centered by the centering rollers 32a, 33a and does not deviate in the width direction.

特開２０１１−１１０７３５号公報JP 2011-110735 A

このものは、内部に幅方向に対して傾斜した多数本のスチールコードが埋設されている帯状部材を、軸線回りに回転している被巻付け体の外周に供給して巻付ける帯状部材の供給巻付け装置であって、前記帯状部材を被巻付け体に向かって搬送する搬送コンベアと、上下方向に延びる軸線回りに回転可能で、帯状部材の幅方向両端が転がり接触するガイド部を有し、該帯状部材に対しセンタリングを行うセンタリングローラとを備えたものである。 This is a supply of a belt-like member that is wound by supplying a belt-like member having a large number of steel cords embedded in the width direction to the outer periphery of the wound body rotating around the axis. A winding device, comprising a conveyor that conveys the belt-shaped member toward the body to be wound, and a guide portion that is rotatable about an axis extending in the vertical direction, and whose widthwise ends of the belt-shaped member are in rolling contact with each other. And a centering roller for centering the belt-like member.

しかしながら、このような従来の帯状部材の供給巻付け装置にあっては、帯状部材は、内部に幅方向に対して傾斜したスチールコードが埋設されていることから、曲げ剛性の値が比較的高いものであるため、被巻付け体に対し帯状部材がかなり巻付けられて終端部だけが残された巻付け終了直前となると、質量が小さくなった（軽量となった）未巻付けの帯状部材の終端部はスチールコードの弾性復元力によって水平な状態から終端に向かうに従い浮き上がるよう傾斜してしまうのである。そして、前述のような傾斜により帯状部材の終端部がセンタリングローラのガイド部から上方に離脱してしまうと、ガイド部より上側は該ガイド部より小径の軸部が存在するか、あるいは、上側の軸部も存在していないため、該帯状部材の終端部を幅方向両側から拘束するものがなくなってしまい、この結果、帯状部材にセンターずれが生じて被巻付け体に対する帯状部材の巻付け品質が低下してしまうという課題があった。また、このような事態を解消するため、手作業でセンターずれを修正することも行われているが、このような修正作業を行うと、作業能率が低下してしまうという課題があった。 However, in such a conventional belt-like member supply winding apparatus, the steel ribbon that is inclined with respect to the width direction is embedded in the belt-like member, so that the value of bending rigidity is relatively high. Therefore, when it is just before the end of winding in which the belt-shaped member is considerably wound around the body to be wound and only the terminal portion is left, the mass is reduced (lightweight). The end portion of the steel plate is inclined so as to float up from the horizontal state toward the end by the elastic restoring force of the steel cord. When the end portion of the belt-like member is separated upward from the guide portion of the centering roller due to the inclination as described above, a shaft portion having a smaller diameter than the guide portion exists above the guide portion, or Since there is no shaft portion, there is no need to restrain the end portion of the belt-like member from both sides in the width direction. As a result, the belt-like member is displaced from the center, and the winding quality of the belt-like member around the body to be wound is eliminated. There was a problem that would decrease. Moreover, in order to eliminate such a situation, the center shift is also corrected manually, but when such a correction operation is performed, there is a problem that the work efficiency is lowered.

この発明は、被巻付け体に対する帯状部材の巻付け品質を作業能率を低下させることなく容易に向上させることができる帯状部材の供給巻付け方法および装置を提供することを目的とする。 An object of the present invention is to provide a method and an apparatus for supplying and winding a belt-shaped member that can easily improve the winding quality of the belt-shaped member around the wound body without reducing the work efficiency.

このような目的は、第１に、内部に幅方向に対して傾斜した多数本のスチールコードが埋設されている帯状部材を、上下方向に延びる軸線回りに回転可能で、該帯状部材の幅方向両端が転がり接触するガイド部を有するセンタリングローラによりセンタリングしながら、軸線回りに回転している被巻付け体に向かって搬送コンベアにより搬送することで、該被巻付け体の外周に供給して巻付ける工程と、被巻付け体に帯状部材の終端部が巻付けられているとき、前記センタリングローラのうち、被巻付け体に最も近接するセンタリングローラの幅方向内側に設置され、下面が前記センタリングローラのガイド部の上端より下方に位置する規制体より、該帯状部材の終端部の位置を規制する工程とを備えた帯状部材の供給巻付け方法により、達成することができる。 The first purpose is to be able to rotate a belt-like member in which a large number of steel cords inclined in the width direction are embedded around an axis extending in the vertical direction. While being centered by a centering roller having a guide portion whose both ends are in rolling contact, it is transported by a conveyor to a wound body rotating around the axis, thereby being supplied to the outer periphery of the wound body and wound. And when the terminal portion of the belt-like member is wound around the wound body, the centering roller is installed on the inner side in the width direction of the centering roller closest to the wound body, and the lower surface is the centering And a step of regulating the position of the end portion of the belt-shaped member from a regulating body located below the upper end of the guide portion of the roller. It can be.

第２に、内部に幅方向に対して傾斜した多数本のスチールコードが埋設されている帯状部材を、軸線回りに回転している被巻付け体の外周に供給して巻付ける帯状部材の供給巻付け装置であって、前記帯状部材を被巻付け体に向かって搬送する搬送コンベアと、上下方向に延びる軸線回りに回転可能で、帯状部材の幅方向両端が転がり接触するガイド部を有し、該帯状部材に対しセンタリングを行うセンタリングローラと、前記センタリングローラのうち、被巻付け体に最も近接するセンタリングローラの幅方向内側に設置され、下面が前記センタリングローラのガイド部の上端より下方に位置することで、帯状部材の終端部の位置を規制する規制体とを備えた帯状部材の供給巻付け装置により、達成することができる。 Second, supply of a belt-like member for supplying and winding a belt-like member in which a large number of steel cords inclined with respect to the width direction are embedded on the outer periphery of the wound body rotating around the axis A winding device, comprising a conveyor that conveys the belt-shaped member toward the body to be wound, and a guide portion that is rotatable about an axis extending in the vertical direction, and whose widthwise ends of the belt-shaped member are in rolling contact with each other. A centering roller for centering the belt-shaped member, and a centering roller of the centering roller that is closest to the wound body and disposed on the inner side in the width direction, and the lower surface is below the upper end of the guide portion of the centering roller By being positioned, this can be achieved by a supply member winding device for a belt-shaped member provided with a regulating body that regulates the position of the end portion of the belt-shaped member.

この発明においては、被巻付け体に最も近接するセンタリングローラの幅方向内側に、下面が前記センタリングローラのガイド部の上端より下方に位置する規制体を設置したので、帯状部材の曲げ剛性の値が比較的高いことで、該帯状部材の終端部が被巻付け体への巻付け終了直前に弾性復元力によって終端に向かうに従い浮き上がるよう傾斜しようとしても、該帯状部材の終端部は前記規制体により上方から押さえられてセンタリングローラのガイド部の上端より下方となるよう位置規制される。この結果、該帯状部材の終端部の幅方向両端はセンタリングローラに接触し、これにより、前記終端部は継続してセンタリングが施されて幅方向ずれが生じることはない。このようなことから、作業能率を低下させることなく、被巻付け体に対する帯状部材の巻付け品質を向上させることができる。 In this invention, since the regulating body whose lower surface is positioned below the upper end of the guide portion of the centering roller is installed on the inner side in the width direction of the centering roller closest to the wound body, the value of the bending rigidity of the belt-shaped member Is relatively high, even if the end of the band-shaped member is inclined to float up toward the end by the elastic restoring force immediately before the end of winding on the wound body, the end of the band-shaped member is Therefore, the position of the centering roller is regulated so as to be lower than the upper end of the guide portion of the centering roller. As a result, both ends in the width direction of the end portion of the belt-shaped member are in contact with the centering roller, and thus the end portion is continuously centered and no shift in the width direction occurs. For this reason, it is possible to improve the winding quality of the belt-shaped member around the wound body without reducing the work efficiency.

また、請求項３に記載のように構成すれば、帯状部材の終端側剣先部は規制体により磁石からなる矯正部材と重なり合う高さに規制され、この結果、前記終端側剣先部に変形が生じていても、該変形を矯正部材により容易に矯正することができる。さらに、請求項４に記載のように構成すれば、規制体と帯状部材との摺接により帯状部材が傷付く事態を防止することができるとともに、帯状部材のばたつきを抑制することができる。また、請求項５に記載のように構成すれば、帯状部材の幅変更に問題なく対応することができる。さらに、請求項６に記載のように構成すれば、規制体と帯状部材との摺接を抑制することができる。 According to the third aspect of the present invention, the terminal side sword tip portion of the belt-shaped member is regulated by the restricting body so as to overlap with the correction member made of a magnet, and as a result, the end side sword tip portion is deformed. Even so, the deformation can be easily corrected by the correction member. Furthermore, if comprised as described in Claim 4, while being able to prevent the situation where a strip | belt-shaped member gets damaged by the sliding contact of a control body and a strip | belt-shaped member, the flapping of a strip | belt-shaped member can be suppressed. Moreover, if comprised as described in Claim 5, it can respond to a width change of a strip | belt-shaped member without a problem. Furthermore, if it comprises as described in Claim 6, the sliding contact of a control body and a strip | belt-shaped member can be suppressed.

この発明の実施形態１を示す一部破断平面図である。It is a partially broken top view which shows Embodiment 1 of this invention. 図１のＩ−Ｉ矢視図である。It is the II arrow directional view of FIG. 図１のII−II矢視断面図である。It is II-II arrow sectional drawing of FIG.

以下、この発明の実施形態１を図面に基づいて説明する。
図１、２において、11は円筒状を呈する拡縮径可能な被巻付け体としての成形ドラムであり、この成形ドラム11は図示していない駆動部から駆動力を受けて水平な軸線回りに回転することができる。なお、この発明においては、前記被巻付け体として、外表面が加硫済タイヤ（製品タイヤ）の内表面と同一形状である剛体コア、あるいは、成形ドラムの周囲に成形され、断面略円弧状に膨出変形したカーカス層等からなるタイヤ中間体を用いてもよい。12は前記成形ドラム11の後方に設置された供給巻付け装置であり、この供給巻付け装置12は水平面内を前後方向に延びる下部フレーム13と、該下部フレーム13の上方に配置され、該下部フレーム13に平行に延びる上部フレーム14とを有している。 Embodiment 1 of the present invention will be described below with reference to the drawings.
In FIGS. 1 and 2, reference numeral 11 denotes a forming drum as a wound body having a cylindrical shape capable of expanding and contracting, and this forming drum 11 receives a driving force from a driving unit (not shown) and rotates around a horizontal axis. can do. In the present invention, the wound body is molded around a rigid core having an outer surface that is the same shape as the inner surface of a vulcanized tire (product tire), or around a molding drum, and has a substantially arc-shaped cross section. A tire intermediate body made of a carcass layer or the like bulged and deformed may be used. 12 is a supply winding device installed at the rear of the forming drum 11. The supply winding device 12 is disposed above the lower frame 13 with a lower frame 13 extending in the front-rear direction in a horizontal plane, And an upper frame 14 extending in parallel with the frame 13.

15は前後方向に等距離離れて設置された複数の搬送ローラであり、これらの搬送ローラ15は前記成形ドラム11の軸線に平行に延びるとともに、軸方向両端部が下部フレーム13に回転可能に支持されている。そして、前記搬送ローラ15のうち少なくとも１本の搬送ローラ15には図示していないモータ等の駆動源から駆動力が付与される。前述した下部フレーム13、搬送ローラ15、駆動源は全体として、被巻付け体としての成形ドラム11に向かって、前後方向に延びるベルトプライ、ワイヤーチェーファー等（ここでは、ベルトプライ）からなる帯状部材16を搬送する搬送コンベア17を構成する。なお、この実施形態においては、搬送コンベアとしてローラコンベアを用いたが、この発明においてはベルトコンベアを用いるようにしてもよい。 Reference numeral 15 denotes a plurality of conveying rollers installed equidistantly in the front-rear direction. These conveying rollers 15 extend parallel to the axis of the forming drum 11 and are supported at both ends in the axial direction on the lower frame 13 so as to be rotatable. Has been. A driving force is applied to at least one of the transport rollers 15 from a drive source such as a motor (not shown). The lower frame 13, the transport roller 15, and the drive source as described above as a whole are belt-shaped belt belts, wire chafers, and the like (here, belt plies) extending in the front-rear direction toward the forming drum 11 as a wound body. A transport conveyor 17 that transports the member 16 is configured. In this embodiment, a roller conveyor is used as the transport conveyor. However, in the present invention, a belt conveyor may be used.

前記帯状部材16は長手方向長が前記成形ドラム11の１周長と実質上同一で、その内部に幅方向に対して同一角度、例えば55〜80度で傾斜した多数本の強磁性体材料からなるスチールコード21が埋設されている。また、前記帯状部材16は始端（前端）および終端（後端）がスチールコード21に沿って斜め切断されているので、始端および終端に幅方向に対して同一角度で傾斜した傾斜面がそれぞれ形成され、この結果、該帯状部材16は細長い平行四辺形を呈することになる。このように帯状部材16の始端および終端に傾斜した傾斜面が形成されると、該帯状部材16の始端側傾斜面22の後端16ｃ（鈍角で交差する位置）より前側には、幅方向端16ｂを一辺とする直角三角形の始端側剣先部23が形成され、一方、図示していないが該帯状部材16の終端側傾斜面の前端より後側には、幅方向端16ａを一辺とする直角三角形の終端側剣先部が形成される。 The belt-like member 16 has a length in the longitudinal direction substantially the same as one circumference of the forming drum 11 and is made of a plurality of ferromagnetic materials inclined at the same angle, for example, 55 to 80 degrees with respect to the width direction. A steel cord 21 is embedded. In addition, since the belt-like member 16 has a starting end (front end) and a terminal end (rear end) obliquely cut along the steel cord 21, inclined surfaces inclined at the same angle with respect to the width direction are formed at the starting end and the terminal end, respectively. As a result, the belt-like member 16 has an elongated parallelogram. Thus, when the inclined surface inclined at the starting end and the terminal end of the band-shaped member 16 is formed, the width direction end is located on the front side of the rear end 16c (position intersecting at an obtuse angle) of the starting end-side inclined surface 22 of the band-shaped member 16. A right-sided triangular sword tip 23 having a side 16b is formed. On the other hand, although not shown, a right-angled side having a width direction end 16a on the rear side of the front end of the terminal-side inclined surface of the band-like member 16 is shown. A triangular sword tip is formed.

そして、搬送ローラ15上に載置されている帯状部材16は、いずれかの搬送ローラ15が駆動回転されることで、軸線回りに回転している成形ドラム11の外周に供給され、該成形ドラム11の周囲に全周に亘って巻付けられるとともに、その始、終端（始端側傾斜面22と終端側傾斜面）同士が接合されて円筒状のタイヤ構成部材が成形される。前記上部フレーム14の前、後端部下面にはそれぞれ成形ドラム11の軸線に平行に延びるガイドレール26が固定され、これらガイドレール26には前記下部フレーム13と上部フレーム14との間において前後方向に延びる一対の可動プレート27、28の前、後端部上面に取り付けられたスライドベアリング29が摺動可能に係合している。そして、前記一対の可動プレート27、28は帯状部材16の幅方向中央から常に等距離だけ幅方向外側に離れるとともに、図示していない駆動機構、例えば、リンク機構、シリンダ等から駆動力を受けて帯状部材16の幅方向に同期移動し互いに接近離隔する。 The belt-like member 16 placed on the conveying roller 15 is supplied to the outer periphery of the forming drum 11 rotating around the axis line by driving and rotating any of the conveying rollers 15. 11 is wound around the entire circumference, and its start and end (start end side inclined surface 22 and end side inclined surface) are joined together to form a cylindrical tire constituent member. Guide rails 26 extending in parallel to the axis of the forming drum 11 are fixed to the lower surfaces of the front and rear end portions of the upper frame 14, respectively. The guide rails 26 are arranged in the front-rear direction between the lower frame 13 and the upper frame 14. A slide bearing 29 attached to the upper surfaces of the front and rear end portions of the pair of movable plates 27 and 28 extending in a slidably engaged manner. The pair of movable plates 27 and 28 are always separated outward in the width direction by an equal distance from the center in the width direction of the band-shaped member 16 and receive a driving force from a driving mechanism (not shown) such as a link mechanism or a cylinder. The belt-like members 16 move in the width direction in synchronization with each other and move away from each other.

32、33は上下方向に延びる軸線回りに回転可能な複数対のセンタリングローラであり、これらのセンタリングローラ32、33は大径で円柱状を呈するガイド部34、35と、該ガイド部34、35の上端から上方に向かって延び前記ガイド部34、35と同軸でこれらガイド部34、35より小径である軸部36、37とからなり、前記軸部36、37が可動プレート27、28に下方からそれぞれ挿入されることで、これらセンタリングローラ32、33は可動プレート27、28に下側において回転可能に支持されている。なお、この発明においては、前記センタリングローラを該センタリングローラより下方に設置された可動プレートに回転可能に支持させてもよく、この場合には該センタリングローラのガイド部の上端より上側には軸部も存在しない。 32 and 33 are a plurality of pairs of centering rollers that can rotate around an axis extending in the vertical direction. These centering rollers 32 and 33 are guide portions 34 and 35 having a large diameter and a cylindrical shape, and the guide portions 34 and 35. The shaft portions 36 and 37 are coaxial with the guide portions 34 and 35 and have a smaller diameter than the guide portions 34 and 35. The shaft portions 36 and 37 are below the movable plates 27 and 28. The centering rollers 32 and 33 are rotatably supported by the movable plates 27 and 28 on the lower side. In the present invention, the centering roller may be rotatably supported by a movable plate disposed below the centering roller. In this case, a shaft portion is provided above the upper end of the guide portion of the centering roller. Does not exist.

ここで、前記センタリングローラ32、33は帯状部材16の搬送方向（前後方向）に離れて配置されるとともに、前記ガイド部34、35の軸方向中央部は搬送コンベア17上の帯状部材16と同一高さに位置している。この結果、センタリングローラ32、33のガイド部34、35の外周が帯状部材16の幅方向両端（幅方向端16ａおよび16ｂ）にそれぞれ転がり接触すると、該帯状部材16はセンタリングローラ32、33により両側から押されてセンタリングされ、帯状部材16の幅方向中央が成形ドラム11の巻付け領域の軸方向中央に合致される。なお、この実施形態のようにセンタリングローラ32、33を帯状部材16の幅方向に移動可能な可動プレート27、28に支持させるようにすれば、帯状部材16の幅に変更があったとき、可動プレート27、28を帯状部材16の幅方向に同一量だけ移動させて接近離隔させることで、前記幅変更に容易に対処することができるが、常に一定幅の帯状部材16が供給されるような場合には、可動プレート27、28を一定位置に固定するようにしてもよい。 Here, the centering rollers 32 and 33 are arranged away from each other in the transport direction (front-rear direction) of the belt-like member 16, and the axial center of the guide portions 34 and 35 is the same as the belt-like member 16 on the transport conveyor 17. Located at height. As a result, when the outer circumferences of the guide portions 34 and 35 of the centering rollers 32 and 33 are in rolling contact with both ends in the width direction (width direction ends 16a and 16b) of the band-shaped member 16, the band-shaped member 16 is moved to both sides by the centering rollers 32 and 33. And the center of the belt-like member 16 in the width direction is aligned with the center of the winding region of the forming drum 11 in the axial direction. If the centering rollers 32 and 33 are supported by the movable plates 27 and 28 that are movable in the width direction of the belt-like member 16 as in this embodiment, when the width of the belt-like member 16 is changed, the centering rollers 32 and 33 are movable. By moving the plates 27 and 28 by the same amount in the width direction of the band-shaped member 16 and approaching and separating them, the width change can be easily dealt with, but the band-shaped member 16 having a constant width is always supplied. In some cases, the movable plates 27 and 28 may be fixed at a fixed position.

前記センタリングローラ32のうち、成形ドラム11に最も近接する（最前側に位置する）センタリングローラ32ａ、33ａの近傍、ここではセンタリングローラ32ａ、33ａと、該センタリングローラ32ａ、33ａの直後に配置され成形ドラム11から２番目に近接する位置に位置するセンタリングローラ32ｂ、33ｂとの間で可動プレート27、28の直下にはネオジム磁石、アルニコ磁石、マサリウムコバルト磁石、フェライト磁石等の磁石（永久磁石）から構成された矯正部材40、41がそれぞれ設置され、これらの矯正部材40、41は帯状部材16の幅方向端16ａ、16ｂより幅方向外側に配置されている。また、これら矯正部材40、41の上端はセンタリングローラ32、33のガイド部34、35の上端より若干下方に位置しており、さらに、該矯正部材40、41の高さ方向中央部は搬送コンベア17上の帯状部材16と同一高さに位置している。なお、この発明においては、前記矯正部材を電磁石から構成してもよい。 Of the centering rollers 32, the centering rollers 32a and 33a that are closest to the forming drum 11 (positioned at the foremost side), in the vicinity thereof, here are the centering rollers 32a and 33a, and immediately after the centering rollers 32a and 33a. Magnets (permanent magnets) such as neodymium magnets, alnico magnets, mazalium cobalt magnets, and ferrite magnets just below the movable plates 27 and 28 between the centering rollers 32b and 33b located at the position closest to the drum 11 The straightening members 40 and 41 configured from the above are respectively installed, and these straightening members 40 and 41 are arranged on the outer side in the width direction from the width direction ends 16a and 16b of the belt-like member 16. The upper ends of the correction members 40 and 41 are located slightly below the upper ends of the guide portions 34 and 35 of the centering rollers 32 and 33, and the central portions of the correction members 40 and 41 in the height direction are transport conveyors. 17 is located at the same height as the strip 16 on the top. In the present invention, the correction member may be composed of an electromagnet.

42、43は前記矯正部材40、41の幅方向外側で可動プレート27、28の下面にそれぞれ固定された支持プレートであり、これら支持プレート42、43は上下方向に延在している。前記支持プレート42、43には成形ドラム11の軸線に平行に延びる移動機構としてのシリンダ44、45のロッド側がそれぞれ取り付けられ、これらシリンダ44、45のピストンロッド46、47の先端には前記矯正部材40、41が支持体48、49を介して取り付けられている。この結果、前記シリンダ44、45が作動してピストンロッド46、47が突出したり引っ込んだりすると、矯正部材40、41は帯状部材16の幅方向に個別に移動する。なお、この発明においては、前記移動機構としてリンク機構あるいはラック・ピニオン機構を用いるようにしてもよい。 Reference numerals 42 and 43 denote support plates fixed to the lower surfaces of the movable plates 27 and 28 on the outer side in the width direction of the correction members 40 and 41, respectively, and these support plates 42 and 43 extend in the vertical direction. Rods of cylinders 44 and 45 as moving mechanisms extending parallel to the axis of the forming drum 11 are respectively attached to the support plates 42 and 43, and the correction members are attached to the ends of the piston rods 46 and 47 of the cylinders 44 and 45, respectively. 40 and 41 are attached via supports 48 and 49. As a result, when the cylinders 44 and 45 are operated and the piston rods 46 and 47 protrude or retract, the correction members 40 and 41 individually move in the width direction of the belt-like member 16. In the present invention, a link mechanism or a rack and pinion mechanism may be used as the moving mechanism.

そして、前記剣先部が矯正部材40、41間に移動してくると、前記シリンダ44またはシリンダ45を作動してピストンロッド46またはピストンロッド47を突出させ、矯正部材40または矯正部材41を帯状部材16の幅方向端16ａまたは幅方向端16ｂに接近させる。ここで、前述した帯状部材16の始端側剣先部23、終端側剣先部はコーティングゴムの収縮等により幅方向内側（幅方向中央）に向かって変形することが多いが、このような変形は前記矯正部材40または矯正部材41が始端側剣先部23または終端側剣先部内のスチールコード21を磁力により吸引することで矯正することができる。 When the sword tip moves between the correction members 40 and 41, the cylinder 44 or the cylinder 45 is operated to cause the piston rod 46 or the piston rod 47 to protrude, and the correction member 40 or the correction member 41 is moved to the belt-shaped member. It is made to approach 16 width direction edge 16a or width direction edge 16b. Here, the start side sword tip 23 and the end side sword tip of the belt-shaped member 16 described above are often deformed inward in the width direction (center in the width direction) due to shrinkage of the coating rubber, etc. The straightening member 40 or the straightening member 41 can be straightened by attracting the steel cord 21 in the start side sword tip 23 or the end side sword tip by a magnetic force.

ここで、前記矯正部材40、41が帯状部材16に最も接近したとき、該矯正部材40、41と幅方向端16ａ、16ｂとの間に僅かな、例えば 0.5mm程度の隙間を形成することが、前記剣先部の変形を効果的に矯正できるので、好ましい。一方、前記剣先部を除く帯状部材16の長手方向中央部が矯正部材40、41間を通過しているときには、前記シリンダ44、45の作動によりピストンロッド46、47を引っ込ませる。この結果、矯正部材40、41が幅方向端16ａ、16ｂから離隔してこれらの間の隙間が増大し、これにより、帯状部材16の走行時に幅方向端16ａ、16ｂに露出しているスチールコード21の切断端と矯正部材40、41との接触が効果的に回避される。 Here, when the straightening members 40 and 41 are closest to the belt-like member 16, a slight gap of, for example, about 0.5 mm may be formed between the straightening members 40 and 41 and the width direction ends 16a and 16b. It is preferable because the deformation of the sword tip can be effectively corrected. On the other hand, when the central portion in the longitudinal direction of the belt-like member 16 excluding the sword tip portion passes between the correction members 40 and 41, the piston rods 46 and 47 are retracted by the operation of the cylinders 44 and 45. As a result, the straightening members 40 and 41 are separated from the width direction ends 16a and 16b, and the gaps between them are increased. As a result, the steel cord exposed to the width direction ends 16a and 16b when the belt-shaped member 16 travels. Contact between the cut end 21 and the correction members 40 and 41 is effectively avoided.

なお、この発明においては、前記矯正部材は垂直軸線回りにフリー回転可能な磁石からなるローラであってもよく、この場合には、これらローラの配置位置を帯状部材の幅方向端に転がり接触する位置とすることもできる。前述した矯正部材40、41、支持プレート42、43、シリンダ44、45、支持体48、49は全体として、変形した剣先部を矯正する矯正手段52、53を構成する。54、55は前記矯正手段52、53と前記センタリングローラ32ｂ、33ｂとの間に設置され前記矯正手段52、53と同一構成である後側矯正手段であり、これら後側矯正手段54、55は変形した剣先部を吸引することで、該剣先部の矯正をより確実なものとする。なお、この発明においては、前記センタリングローラ32ａを矯正手段52と後側矯正手段54との間に、また、前記センタリングローラ33ａを矯正手段53と後側矯正手段55との間に設置してもよい。 In the present invention, the straightening member may be a roller made of a magnet that can freely rotate around a vertical axis, and in this case, the arrangement position of these rollers is in rolling contact with the widthwise end of the belt-like member. It can also be a position. The correction members 40 and 41, the support plates 42 and 43, the cylinders 44 and 45, and the supports 48 and 49 described above constitute correction means 52 and 53 that correct the deformed sword tip as a whole. 54 and 55 are rear correction means installed between the correction means 52 and 53 and the centering rollers 32b and 33b and having the same configuration as the correction means 52 and 53. These rear correction means 54 and 55 are By sucking the deformed sword tip portion, the sword tip portion is more reliably corrected. In the present invention, the centering roller 32a may be installed between the correcting means 52 and the rear correcting means 54, and the centering roller 33a may be installed between the correcting means 53 and the rear correcting means 55. Good.

図１、２、３において、58、59は上端部が可動プレート27、28の幅方向内側面に固定された規制部材であり、これらの規制部材58、59は帯状部材16に向かって下方に延びる延在体60、61と、これら延在体60、61の下端から幅方向内側、即ち、帯状部材16の幅方向中央に向かって搬送コンベア17の搬送面（搬送ローラ15の上端を結ぶ面）に平行に延びる規制体62、63とから構成されている。この結果、前記規制体62、63は前記センタリングローラ32ａ、33ａの幅方向内側に、これらセンタリングローラ32ａ、33ａから若干離れて設置されることになり、しかも、該規制体62、63の下面62ａ、63ａはセンタリングローラ32ａ、33ａのガイド部34、35の上端より下方に位置している。 In FIGS. 1, 2, and 3, 58 and 59 are restricting members whose upper ends are fixed to the inner surfaces in the width direction of the movable plates 27 and 28, and these restricting members 58 and 59 are directed downward toward the belt-like member 16. Extending bodies 60, 61 extending from the lower ends of these extending bodies 60, 61 to the inner side in the width direction, that is, toward the center in the width direction of the belt-shaped member 16, the surface connecting the upper ends of the transport rollers 15 ) And restricting bodies 62 and 63 extending in parallel with each other. As a result, the restricting bodies 62 and 63 are installed on the inner side in the width direction of the centering rollers 32a and 33a, slightly apart from the centering rollers 32a and 33a, and the lower surfaces 62a of the restricting bodies 62 and 63 are arranged. 63a are positioned below the upper ends of the guide portions 34, 35 of the centering rollers 32a, 33a.

ここで、前述した帯状部材16は内部に幅方向に対して傾斜した多数本のスチールコード21が埋設されているため、長手方向の曲げ剛性の値は比較的高いものである。このため、該帯状部材16が成形ドラム11にかなり巻付けられて、その終端部だけが残された巻付け終了直前となると、巻付け位置より後側の質量が小さくなった（軽量となった）帯状部材16の終端部は、図２に仮想線で示すように、スチールコード21の弾性復元力によって水平な状態から終端に向かうに従い浮き上がるよう傾斜し、センタリングローラ32ａ、33ａのガイド部34、35から上方に離脱しようとする。 Here, since the strip-shaped member 16 described above has a large number of steel cords 21 inclined with respect to the width direction embedded therein, the value of the bending rigidity in the longitudinal direction is relatively high. For this reason, when the belt-like member 16 is considerably wound around the forming drum 11 and immediately before the end of winding, in which only the terminal portion is left, the mass on the rear side from the winding position is reduced (lightweight) ) As shown by phantom lines in FIG. 2, the end portion of the belt-like member 16 is inclined so as to float up from the horizontal state toward the end by the elastic restoring force of the steel cord 21, and the guide portions 34 of the centering rollers 32a and 33a, Trying to leave upwards from 35.

しかしながら、この実施形態では前述のように、規制体62、63をセンタリングローラ32ａ、33ａの幅方向内側に設置するとともに、該規制体62、63の下面62ａ、63ａをセンタリングローラ32ａ、33ａのガイド部34、35の上端より下方に位置させるようにしたので、帯状部材16の終端部が成形ドラム11への巻付け終了直前に弾性復元力によって終端に向かうに従い浮き上がるよう傾斜しようとしても、該帯状部材16の終端部は前記規制体62、63により上方から押さえられてセンタリングローラ32ａ、33ａのガイド部34、35の上端より下方となるよう位置規制される。 However, in this embodiment, as described above, the regulating bodies 62 and 63 are installed inside the centering rollers 32a and 33a in the width direction, and the lower surfaces 62a and 63a of the regulating bodies 62 and 63 are guided by the centering rollers 32a and 33a. Since the end portions of the strip members 16 are positioned below the upper ends of the portions 34 and 35, even if the end portions of the strip members 16 are inclined to float up toward the end by the elastic restoring force immediately before the winding of the molding drum 11, the strip portions The end portion of the member 16 is pressed from above by the restriction bodies 62 and 63, and the position is regulated so as to be below the upper ends of the guide portions 34 and 35 of the centering rollers 32a and 33a.

この結果、該帯状部材16の終端部の幅方向両端16ａ、16ｂはセンタリングローラ32ａ、33ａに常に転がり接触し、これにより、前記終端部は継続してセンタリングが施され幅方向ずれが生じることはない。このようにすることで作業能率を低下させることなく、成形ドラム11に対する帯状部材16の巻付け品質を向上させることができる。なお、前記規制体62、63の下面62ａ、63ａをガイド部34、35の上端から上方に帯状部材16の肉厚ｔ未満の距離だけ離して設置することも考えられるが、このようにすると、走行中の帯状部材16が規制体62、63とガイド部34、35との間の間隙に侵入して挟み込まれることがあるので、用いることはできない。 As a result, both ends 16a and 16b in the width direction of the end portion of the band-shaped member 16 are always in rolling contact with the centering rollers 32a and 33a, and thus the end portion is continuously centered and the width direction is shifted. Absent. By doing so, it is possible to improve the winding quality of the belt-like member 16 around the forming drum 11 without reducing the work efficiency. In addition, it is conceivable that the lower surfaces 62a and 63a of the restricting bodies 62 and 63 are installed away from the upper ends of the guide portions 34 and 35 by a distance less than the thickness t of the band-shaped member 16, but in this way, Since the traveling belt-like member 16 may enter the gap between the regulating bodies 62 and 63 and the guide portions 34 and 35 and be sandwiched, it cannot be used.

また、前記規制体62、63は矯正手段52、53、後側矯正手段54、55の矯正部材40、41の幅方向内側まで後側に向かって延在しているとともに、該規制体62、63の下面62ａ、63ａは矯正手段52、53、後側矯正手段54、55の矯正部材40、41の上端より下方に位置している。この結果、帯状部材16の終端側剣先部は規制体62、63により上方から押さえられて前記矯正部材40、41と重なり合う高さに位置規制される。この結果、帯状部材16の終端側剣先部は矯正部材40、41間を通過する際、該矯正部材40、41により確実に吸引され、これにより、該終端側剣先部に変形が生じていても、該変形は矯正部材40、41により容易かつ効果的に矯正される。 Further, the regulation bodies 62, 63 extend toward the rear side to the inside in the width direction of the correction members 40, 41 of the correction means 52, 53 and the rear correction means 54, 55, and the restriction bodies 62, The lower surfaces 62a and 63a of the 63 are positioned below the upper ends of the correcting members 40 and 41 of the correcting means 52 and 53 and the rear correcting means 54 and 55, respectively. As a result, the end-side sword tip portion of the belt-like member 16 is pressed from above by the restrictors 62 and 63, and the position thereof is restricted to a height that overlaps the correction members 40 and 41. As a result, the end side sword tip of the belt-like member 16 is reliably sucked by the correction members 40 and 41 when passing between the correction members 40 and 41, so that even if the end side sword tip is deformed. The deformation is easily and effectively corrected by the correction members 40 and 41.

ここで、前述した搬送コンベア17の搬送面から規制体62、63の下面62ａ、63ａまでの距離Ｌは、帯状部材16の肉厚ｔの 1.5〜 4.0倍の範囲内とすることが好ましい。その理由は、前記距離Ｌが肉厚ｔの 1.5倍未満であると、帯状部材16の搬送時における浮き上がりにより、帯状部材16が規制体62、63に摺接して該帯状部材16が傷付くおそれがあり、一方、前記距離Ｌが肉厚ｔの 4.0倍を超えると、帯状部材16の搬送時に該帯状部材16がばたついて帯状部材16が傷付くおそれがあるが、前述の範囲内とすると、規制体62、63と帯状部材16との摺接により帯状部材16が傷付く事態を防止することができるとともに、帯状部材16のばたつきを抑制することができるからである。 Here, the distance L from the transport surface of the transport conveyor 17 to the lower surfaces 62a and 63a of the regulating bodies 62 and 63 is preferably in the range of 1.5 to 4.0 times the thickness t of the strip-shaped member 16. The reason is that if the distance L is less than 1.5 times the wall thickness t, the belt-like member 16 may be slid into contact with the regulating bodies 62 and 63 due to the lifting of the belt-like member 16 during transportation, and the belt-like member 16 may be damaged. On the other hand, if the distance L exceeds 4.0 times the wall thickness t, the belt-like member 16 may flutter during transportation of the belt-like member 16, and the belt-like member 16 may be damaged. This is because it is possible to prevent the band-shaped member 16 from being damaged due to the sliding contact between the regulating bodies 62 and 63 and the band-shaped member 16, and to suppress the flapping of the band-shaped member 16.

また、前述のように規制体62、63を帯状部材16の幅方向に離して少なくとも一対、ここでは一対設置し、対をなす規制体62、63間に間隙を設けるようにすれば、帯状部材16の幅変更に伴って規制体62、63（可動プレート27、28）間の間隔が変化しても、前記間隙が前記規制体62、63間の間隔の変化を吸収するため、問題なく対応することができ、さらに、巻付け途中の帯状部材16を視認したり、搬送コンベア17から容易に取り出すこともできる。さらに、この実施形態では前記規制体62、63（規制部材58、59）全体を銅合金、アルミニウム合金、プラスチック等の非磁性体材料（常磁性体材料、反磁性体材料）から構成している。 Further, as described above, if the regulating bodies 62 and 63 are separated from each other in the width direction of the strip-shaped member 16, at least a pair, here, a pair is installed, and a gap is provided between the pair of regulating bodies 62 and 63, the strip-shaped member Even if the spacing between the regulating bodies 62 and 63 (movable plates 27 and 28) changes as the width of 16 changes, the gap absorbs the change in the spacing between the regulating bodies 62 and 63, so there is no problem. Furthermore, the belt-like member 16 in the middle of winding can be visually confirmed or can be easily taken out from the conveyor 17. Furthermore, in this embodiment, the entire regulation bodies 62 and 63 (regulation members 58 and 59) are made of a nonmagnetic material (paramagnetic material or diamagnetic material) such as a copper alloy, an aluminum alloy, or plastic. .

その理由は、前記規制体62、63をスチール等の強磁性体材料から構成すると、該規制体62、63が磁石からなる矯正部材40、41により磁化され、規制体62、63が搬送中の帯状部材16（スチールコード21）を引き寄せ、規制体62、63と帯状部材16との摺接を助長してしまうが、前述のように構成すれば、このような摺接を抑制することができるからである。なお、この発明においては、前記規制体（規制部材）の一部、例えば前側部、あるいは、全体を被巻付け体に接近するに従い下方に向かって徐々に傾斜させ（搬送コンベアの搬送面との距離Ｌを徐々に小とし）てもよく、このようにすれば、規制体（規制部材）の直下への終端側剣先部の侵入を容易としながら、終端側剣先部の下方への押込み効果を強力とすることができる。 The reason is that if the restricting bodies 62 and 63 are made of a ferromagnetic material such as steel, the restricting bodies 62 and 63 are magnetized by the correction members 40 and 41 made of magnets, and the restricting bodies 62 and 63 are being conveyed. The belt-like member 16 (steel cord 21) is attracted and facilitates sliding contact between the regulation members 62 and 63 and the belt-like member 16, but if configured as described above, such sliding contact can be suppressed. Because. In the present invention, a part of the regulation body (regulation member), for example, the front side part or the whole is gradually inclined downward as approaching the wound body (with respect to the transport surface of the transport conveyor). The distance L may be gradually reduced), and in this way, the effect of pushing the end side sword tip portion downward can be facilitated while facilitating the entry of the end side sword tip portion directly under the regulating body (regulation member). Can be powerful.

次に、前記実施形態１の作用について説明する。
まず、いずれかの搬送ローラ15を駆動回転させることで、長手方向長が成形ドラム11の１周長と実質上同一長に予め切断されている帯状部材16を、供給コンベア19により下方から支持しながら成形ドラム11に向かって搬送供給する。このとき、可動プレート27、28を駆動機構により互いに離隔させ、センタリングローラ32、33を帯状部材16の幅方向両端16ａ、16ｂから離隔させておくとともに、矯正手段52、53、後側矯正手段54、55を構成するシリンダ44、45のピストンロッド46、47を引っ込ませ、矯正部材40、41を帯状部材16の幅方向両端16ａ、16ｂから離隔させておく。そして、始端側剣先部23が矯正手段53、後側矯正手段55の矯正部材41に対向する位置まで帯状部材16が供給されると、前記搬送ローラ15の回転を停止させ、帯状部材16の成形ドラム11に対する供給を一旦停止させる。なお、この発明においては、この一旦停止時に長尺の帯状部材を切断して、長手方向長が成形ドラム11の１周長と実質上同一長の帯状部材16を切り出すようにしてもよい。 Next, the operation of the first embodiment will be described.
First, a belt-like member 16 whose longitudinal length is cut in advance to be substantially the same as one circumference of the forming drum 11 is supported from below by a feed conveyor 19 by driving and rotating one of the conveying rollers 15. While being conveyed toward the forming drum 11. At this time, the movable plates 27 and 28 are separated from each other by the drive mechanism, and the centering rollers 32 and 33 are separated from both ends 16a and 16b in the width direction of the belt-like member 16, and the correction means 52 and 53, the rear side correction means 54 The piston rods 46 and 47 of the cylinders 44 and 45 constituting the cylinder 55 are retracted, and the correction members 40 and 41 are separated from the widthwise ends 16a and 16b of the belt-like member 16. Then, when the belt-like member 16 is supplied to the position where the start end side sword tip portion 23 faces the straightening member 41 of the straightening means 53 and the backside straightening means 55, the rotation of the conveying roller 15 is stopped and the belt-like member 16 is formed. The supply to the drum 11 is temporarily stopped. In the present invention, the long belt-like member may be cut at the time of this stop to cut out the belt-like member 16 whose longitudinal length is substantially the same as one circumference of the forming drum 11.

次に、可動プレート27、28を駆動機構により互いに接近させ、センタリングローラ32、33のガイド部34、35の外周を帯状部材16の幅方向両端16ａ、16ｂに接触させる。これにより、帯状部材16はセンタリングローラ32、33によりセンタリングされ、帯状部材16の幅方向中央が成形ドラム11の巻付け領域の軸方向中央に合致される。これと同時に、あるいは前記センタリング後に矯正手段53、後側矯正手段55のシリンダ45を作動してピストンロッド47を突出させ、矯正手段53、後側矯正手段55の矯正部材41を帯状部材16の始端部（始端側剣先部23）の幅方向端16ｂに近接対向する位置まで幅方向内側に移動させる。この結果、矯正手段53の矯正部材41は、場合によっては後側矯正手段55の矯正部材41も、始端側剣先部23を磁力により吸引して始端側剣先部23の幅方向内側への変形を矯正する。 Next, the movable plates 27 and 28 are brought close to each other by the drive mechanism, and the outer circumferences of the guide portions 34 and 35 of the centering rollers 32 and 33 are brought into contact with the width direction ends 16a and 16b of the belt-like member 16. Thus, the belt-like member 16 is centered by the centering rollers 32 and 33, and the center in the width direction of the belt-like member 16 is aligned with the center in the axial direction of the winding region of the forming drum 11. At the same time or after the centering, the cylinders 45 of the correction means 53 and the rear correction means 55 are operated to project the piston rod 47, and the correction member 53 and the correction member 41 of the rear correction means 55 are moved to the beginning of the belt-like member 16. Part (start side sword tip 23) is moved inward in the width direction to a position close to and opposed to the width direction end 16b. As a result, the straightening member 41 of the straightening means 53 and the straightening member 41 of the backside straightening means 55 may be deformed inwardly in the width direction of the leading edge side swordtip part 23 by attracting the leading edge side swordtip part 23 with a magnetic force. to correct.

なお、この発明においては、帯状部材16が走行を継続している最中に、矯正部材41により始端側剣先部23の変形を矯正するようにしてもよい。次に、帯状部材16の始端側剣先部23を図示していない保持機構により保持した後、下部フレーム13、上部フレーム14、可動プレート27、28を一体的に前方および下方に斜め移動、あるいは、前方に直線移動させた後下方に直線移動させるが、このような移動は始端側剣先部23の前端が成形ドラム11の直上に到達したとき停止させる。次に、保持機構により始端側剣先部23の前端を成形ドラム11の外周に圧着する。この結果、始端側剣先部23は変形が矯正された状態で成形ドラム11に供給され、始端側剣先部23の成形ドラム11に対する幅方向供給位置が高精度となる。 In the present invention, the deformation of the start end side sword tip portion 23 may be corrected by the correction member 41 while the belt-like member 16 continues running. Next, after holding the starting end side sword tip 23 of the belt-like member 16 by a holding mechanism (not shown), the lower frame 13, the upper frame 14, and the movable plates 27, 28 are integrally moved obliquely forward and downward, or The straight line is moved forward and then the line is moved downward. Such movement is stopped when the front end of the sword tip 23 on the start side reaches just above the forming drum 11. Next, the front end of the start end side sword tip portion 23 is pressed against the outer periphery of the forming drum 11 by the holding mechanism. As a result, the start end side sword tip portion 23 is supplied to the forming drum 11 in a state where the deformation is corrected, and the width direction supply position of the start end side sword tip portion 23 with respect to the forming drum 11 becomes highly accurate.

次に、矯正手段53、後側矯正手段55のシリンダ45を作動してピストンロッド47を引っ込ませ、矯正手段53、後側矯正手段55の矯正部材41を帯状部材16の幅方向端16ｂから離隔させる。この状態で成形ドラム11を軸線回りに回転させる一方、搬送ローラ15を駆動回転させることで、帯状部材16を搬送コンベア17により成形ドラム11の周速度と同一速度で搬送して成形ドラム11の外周に供給するとともに、センタリングローラ32、33によりセンタリングを行いながら成形ドラム11の外周に次々と巻付ける。 Next, the cylinder 45 of the correction means 53 and the rear correction means 55 is operated to retract the piston rod 47, and the correction member 53 and the correction member 41 of the rear correction means 55 are separated from the end 16b in the width direction of the strip member 16. Let In this state, the forming drum 11 is rotated around the axis line, and the conveying roller 15 is driven to rotate so that the belt-like member 16 is conveyed by the conveying conveyor 17 at the same speed as the circumferential speed of the forming drum 11. And is wound around the outer periphery of the forming drum 11 one after another while being centered by the centering rollers 32 and 33.

そして、帯状部材16が成形ドラム11の周囲にかなり巻付けられて、その終端部が巻付けられるようになると、帯状部材16の終端部が弾性復元力によって上方に変形してガイド部34、35の上端より上方に離脱しようとする。しかしながら、この実施形態では、終端側剣先部がセンタリングローラ32ａ、32ｂに到達するまでの間、これらセンタリングローラ32ａ、33ａの幅方向内側に設置された規制体62、63は該帯状部材16の終端部を下方に押し込み、ガイド部34、35の上端より下方となるよう位置規制する。この結果、該帯状部材16の幅方向両端16ａ、16ｂはセンタリングローラ32ａ、33ａに転がり接触し、これにより、該帯状部材16の終端部は終端側剣先部（終端側傾斜面の前端）がセンタリングローラ32ａ、センタリングローラ32ｂに到達するまでセンタリングが施され幅方向ずれが防止される。 Then, when the belt-like member 16 is considerably wound around the forming drum 11 and its terminal portion is wound, the terminal portion of the belt-like member 16 is deformed upward by the elastic restoring force, and the guide portions 34, 35 Try to leave above the top of However, in this embodiment, the regulation bodies 62 and 63 installed on the inner side in the width direction of the centering rollers 32a and 33a until the end side sword tip reaches the centering rollers 32a and 32b. The portion is pushed downward, and the position is regulated so as to be lower than the upper ends of the guide portions 34 and 35. As a result, both ends 16a and 16b in the width direction of the belt-like member 16 are brought into rolling contact with the centering rollers 32a and 33a, whereby the end portion of the belt-like member 16 is centered on the end side sword tip portion (the front end of the end side inclined surface). Centering is performed until the roller 32a and the centering roller 32b are reached, thereby preventing displacement in the width direction.

このようにして帯状部材16の終端側剣先部が矯正手段52、後側矯正手段54の近傍まで搬送されてくると、矯正手段52、後側矯正手段54のシリンダ44が作動してピストンロッド46が突出し、矯正手段52、後側矯正手段54の矯正部材40は帯状部材16の幅方向端16ａに近接対向する位置まで移動する。このとき、帯状部材16の終端側剣先部は前述と同様に上方に変形しようとするが、該帯状部材16の終端側剣先部は規制体62、63により下方に押し込まれ、矯正手段52、後側矯正手段54の矯正部材40の上端より下方となるよう、即ち、矯正部材40と重なり合う高さ位置に位置規制される。この結果、終端剣先部は矯正手段52、後側矯正手段54の矯正部材40に確実に対向することとなり、これにより、終端剣先部は矯正部材40の磁力により吸引され、幅方向内側への変形が容易かつ確実に矯正される。なお、この実施形態において、帯状部材16の搬送を継続している最中に矯正手段52、後側矯正手段54の矯正部材40により終端側剣先部の変形を矯正するようにしたが、この発明においては、始端側剣先部23と同様に帯状部材16の搬送を一旦停止させた状態で、終端側剣先部の変形を矯正するようにしてもよい。 In this way, when the end side sword tip of the belt-like member 16 is conveyed to the vicinity of the correcting means 52 and the rear correcting means 54, the cylinders 44 of the correcting means 52 and the rear correcting means 54 are operated and the piston rod 46 is operated. Protrudes, and the correction member 40 of the correction means 52 and the rear correction means 54 moves to a position close to and opposed to the width direction end 16a of the belt-like member 16. At this time, the end side sword tip portion of the belt-like member 16 tends to be deformed upward in the same manner as described above, but the end side sword tip portion of the belt-like member 16 is pushed downward by the regulating bodies 62, 63, and the correcting means 52, rear The position is regulated so as to be below the upper end of the correction member 40 of the side correction means 54, that is, at a height position overlapping the correction member 40. As a result, the terminal sword tip is surely opposed to the correction member 40 of the correction means 52 and the rear correction means 54, whereby the terminal sword tip is attracted by the magnetic force of the correction member 40 and deformed inward in the width direction. Is easily and reliably corrected. In this embodiment, while the conveyance of the belt-like member 16 is continued, the deformation of the terminal side sword tip is corrected by the correction member 52 and the correction member 40 of the rear side correction unit 54. In the same manner as in the case of the start end side sword tip part 23, the deformation of the end side sword tip part may be corrected in a state where the transport of the belt-like member 16 is temporarily stopped.

そして、前記帯状部材16が成形ドラム11の外周に全周に亘って巻付けられると、該帯状部材16の始、終端（始端側傾斜面22、終端側傾斜面）同士が接合され円筒状のタイヤ構成部材（ベルトプライ）が成形される。その後、前記成形ドラム11の周囲に別の帯状部材（ベルトプライ）が巻付けられ、複数のベルトプライからなるベルト層が形成される。このとき、第１層目の帯状部材16と第２層目の帯状部材16とはスチールコード21の傾斜方向が、通常逆方向となるが、この場合には、矯正手段52、後側矯正手段54が帯状部材16の始端側剣先部の変形を矯正し、矯正手段53、後側矯正手段55が終端側剣先部の変形を矯正する。次に、成形ドラム11の周囲にトレッドゴムが供給されて前記ベルト層の外側に巻付けられ、ベルト・トレッドバンドが成形される。その後、前記ベルト・トレッドバンドは、シェーピングドラムに支持され断面略半円状に膨出変形される途中のグリーンケースの外側に嵌合されてその半径方向外側に貼付けられ、前記タイヤ構成部材（ベルトプライ）を有するグリーンタイヤが成形される。次に、該グリーンタイヤはシェーピングドラムから取り出された後、タイヤ加硫金型内に収納されて加硫され加硫済空気入りタイヤとなる。 Then, when the belt-like member 16 is wound around the outer periphery of the forming drum 11, the start and end (start-end side inclined surface 22, end-side inclined surface) of the band-like member 16 are joined to each other to form a cylindrical shape. A tire component (belt ply) is formed. Thereafter, another belt-like member (belt ply) is wound around the forming drum 11 to form a belt layer composed of a plurality of belt plies. At this time, the first layer belt-like member 16 and the second layer belt-like member 16 are normally opposite in inclination direction of the steel cord 21, but in this case, the correction means 52, the rear side correction means 54 corrects the deformation of the leading end side sword tip portion of the belt-like member 16, and the correcting means 53 and the rear side correcting means 55 correct the deformation of the terminal side sword tip portion. Next, tread rubber is supplied around the forming drum 11 and wound around the outside of the belt layer to form a belt tread band. After that, the belt tread band is fitted to the outside of the green case that is supported by the shaping drum and is swelled and deformed in a substantially semicircular cross section, and is affixed to the outside in the radial direction. A green tire having a ply) is formed. Next, after the green tire is taken out from the shaping drum, it is stored in a tire vulcanizing mold and vulcanized to form a vulcanized pneumatic tire.

この発明は、軸線回りに回転している被巻付け体の外周に帯状部材を供給して巻付ける産業分野に適用できる。 The present invention can be applied to the industrial field in which a belt-like member is supplied and wound around the outer periphery of a wound body rotating around an axis.
