Description

本発明は、成型後のグリーンタイヤを一時的に保持するためのグリーンタイヤ保持装置に関する。 The present invention relates to a green tire holding device for temporarily holding a molded green tire.

空気入りタイヤの製造工程では、種々のゴム材を組み合わせてグリーンタイヤ（未加硫タイヤ）を成型し、その成型したグリーンタイヤを加硫機に供給して加硫を行う。成型されたグリーンタイヤは、加硫機に供給されるまでの間、保持装置によって一時的に保持される。成型後のグリーンタイヤを加硫機まで運搬できるよう、保持装置が運搬台車として構成される場合もある（例えば、特許文献１）。 In the manufacturing process of a pneumatic tire, various rubber materials are combined to form a green tire (unvulcanized tire), and the molded green tire is supplied to a vulcanizer for vulcanization. The molded green tire is temporarily held by the holding device until it is supplied to the vulcanizer. In some cases, the holding device is configured as a carrier so that the molded green tire can be transported to the vulcanizer (for example, Patent Document 1).

グリーンタイヤは、タイヤ軸方向を水平に向けた縦置きの状態で、または、タイヤ軸方向を上下に向けた横置きの状態で保持される。グリーンタイヤを縦置きの状態で保持する場合には、水平に配置されたバーなどを用いてグリーンタイヤを吊り下げることが考えられる（例えば、特許文献２）。しかし、そのようにして保持されたグリーンタイヤは、時間の経過に伴って自重により変形しやすく、加硫後の製品タイヤにおいてユニフォミティの悪化が懸念される。 The green tire is held in a vertical position with the tire axial direction oriented horizontally, or in a horizontal position with the tire axial direction oriented vertically. When the green tire is held in a vertically placed state, it is conceivable to suspend the green tire by using a bar or the like arranged horizontally (for example, Patent Document 2). However, the green tire held in this way is easily deformed by its own weight with the passage of time, and there is a concern that the uniformity of the product tire after vulcanization may be deteriorated.

グリーンタイヤを横置きの状態で保持する場合には、図８のようなリング状部材８にグリーンタイヤ９を載置することが考えられる（例えば、特許文献３）。リング状部材８は、金属やプラスチックで形成されている。下方を向いたグリーンタイヤ９のビード部９１は、中央の穴部８１に配置される。この方式では、タイヤのサイズや品種に応じてビード部９１の外径Ｄ１が変動したときに、ビード部９１がリング状部材８と不適切に干渉することがあり、そのためタイヤ表面に変形（凹み）や外傷を生じる恐れがあった。 When the green tire is held in a horizontal position, it is conceivable to place the green tire 9 on the ring-shaped member 8 as shown in FIG. 8 (for example, Patent Document 3). The ring-shaped member 8 is made of metal or plastic. The bead portion 91 of the green tire 9 facing downward is arranged in the central hole portion 81. In this method, when the outer diameter D1 of the bead portion 91 fluctuates according to the size and type of the tire, the bead portion 91 may improperly interfere with the ring-shaped member 8, and therefore the tire surface is deformed (dented). ) And trauma.

本発明は上記実情に鑑みてなされたものであり、その目的は、横置きの状態で保持したグリーンタイヤの変形や外傷の発生を抑制できる、グリーンタイヤ保持装置を提供することにある。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a green tire holding device capable of suppressing deformation and occurrence of trauma of a green tire held in a horizontal position.

上記目的は、下記の如き本発明により達成できる。即ち、本発明に係るグリーンタイヤ保持装置は、グリーンタイヤが横置きの状態で載置される布材と、前記布材を水平に広げた状態で支持する支持部材とを備え、前記布材が、下方を向いた前記グリーンタイヤのビード部が嵌入される嵌入穴と、前記嵌入穴の周縁で厚み方向に貫通して形成されたスリットとを有するものである。 The above object can be achieved by the present invention as described below. That is, the green tire holding device according to the present invention includes a cloth material on which the green tire is placed horizontally and a support member that supports the cloth material in a horizontally spread state. It has an fitting hole into which the bead portion of the green tire facing downward is fitted, and a slit formed through the peripheral edge of the fitting hole in the thickness direction.

この装置では、水平に広げた状態で支持された布材に、グリーンタイヤが横置きの状態で載置される。下方を向いたビード部が嵌入穴に嵌入されることにより、布材に対するグリーンタイヤの大凡の位置が定まる。また、スリットが形成されていることにより、嵌入穴の周縁部がグリーンタイヤに合わせて下方に撓み、様々なビード部の外径に対して適宜に対応できる。その結果、横置きの状態で保持したグリーンタイヤの変形や外傷の発生を抑制できる。 In this device, green tires are placed horizontally on a cloth material that is supported in a horizontally spread state. By fitting the bead portion facing downward into the fitting hole, the approximate position of the green tire with respect to the cloth material is determined. Further, since the slit is formed, the peripheral edge portion of the fitting hole bends downward in accordance with the green tire, and can appropriately cope with the outer diameters of various bead portions. As a result, it is possible to suppress the occurrence of deformation and trauma of the green tire held in the horizontal position.

四本以上の前記スリットが略等間隔で配置されていることが好ましい。これにより、嵌入穴の周縁部が適度に且つ均等に撓みやすくなり、グリーンタイヤの変形や外傷の発生をより効果的に抑制できる。 It is preferable that the four or more slits are arranged at substantially equal intervals. As a result, the peripheral edge of the fitting hole is easily flexed appropriately and evenly, and the deformation of the green tire and the occurrence of trauma can be suppressed more effectively.

複数の前記支持部材が上下に並べて配置され、上方に位置する前記支持部材が上下回動自在に構成されていることが好ましい。これにより、複数のグリーンタイヤを効率良く積載できる。また、上方に位置する支持部材を上下回動させることで、その下方に位置する支持部材においてグリーンタイヤを出し入れしやすい。 It is preferable that a plurality of the support members are arranged side by side in the vertical direction, and the support members located above the support members are vertically rotatable. As a result, a plurality of green tires can be efficiently loaded. Further, by rotating the support member located above the support member up and down, it is easy to put in and take out the green tire in the support member located below the support member.

キャスターを有することにより、グリーンタイヤ保持装置が運搬台車として構成される。これによって、成型後のグリーンタイヤを加硫機まで運搬し、加硫工程に円滑に移行できる。 By having the casters, the green tire holding device is configured as a transport trolley. As a result, the molded green tire can be transported to the vulcanizer and smoothly transition to the vulcanization process.

本発明の実施形態について図面を参照しながら説明する。 An embodiment of the present invention will be described with reference to the drawings.

図１は、後述するグリーンタイヤ保持装置で保持されるグリーンタイヤ９を示す。グリーンタイヤ９はタイヤ軸方向を上下に向けており、図１の左右方向及び上下方向は、それぞれタイヤ径方向、タイヤ幅方向に相当する。グリーンタイヤ９は、一対のビード部９１と、そのビード部９１の各々からタイヤ径方向外側に延びる一対のサイドウォール部９２と、そのサイドウォール部９２の各々のタイヤ径方向外側端に連なるトレッド部９３とを備える。グリーンタイヤ９の内部には、ビード部９１に配置された環状のビードコア９１ａや、図示しないカーカスやベルトなどの補強層が埋設されている。 FIG. 1 shows a green tire 9 held by a green tire holding device described later. The green tire 9 has the tire axial direction directed up and down, and the left-right direction and the up-down direction in FIG. 1 correspond to the tire radial direction and the tire width direction, respectively. The green tire 9 has a pair of bead portions 91, a pair of sidewall portions 92 extending outward in the tire radial direction from each of the bead portions 91, and a tread portion connected to each tire radial outer end of the sidewall portion 92. It is equipped with 93. Inside the green tire 9, an annular bead core 91a arranged in the bead portion 91 and a reinforcing layer such as a carcass or a belt (not shown) are embedded.

加硫前のグリーンタイヤ９では、ビード部９１がタイヤ幅方向外側に向けて湾曲している。ビード部９１の外径Ｄ１（図８参照）は、タイヤのサイズや品種に応じて種々に変動しうる。このグリーンタイヤ９を加硫機に供給して加硫を行うことにより、製品タイヤが得られる。製品タイヤの外面形状は、加硫機に内蔵された金型によって規定される。加硫後の製品タイヤでは、各ビード部９１がタイヤ幅方向内側に向けて緩やかに湾曲した形状となる。 In the green tire 9 before vulcanization, the bead portion 91 is curved outward in the tire width direction. The outer diameter D1 (see FIG. 8) of the bead portion 91 can vary variously depending on the size and type of the tire. A product tire is obtained by supplying the green tire 9 to a vulcanizer and performing vulcanization. The outer surface shape of the product tire is defined by the mold built into the vulcanizer. In the product tire after vulcanization, each bead portion 91 has a shape that is gently curved inward in the tire width direction.

グリーンタイヤ９は、種々のゴム材を組み合わせて成型される。未加硫状態にあるグリーンタイヤ９は、柔軟で変形しやすい。特にリボン巻き工法で成型されたグリーンタイヤ９は、成型後もしばらくは高温の状態を保っており、タイヤの自重または外的要因によって変形を起こしやすい。リボン巻き工法は、成型ドラムなどの回転支持体に未加硫のゴムリボンを連続的に供給し、そのゴムリボンを螺旋状に巻き付けることにより所望形状のゴム部材を成型する工法である。 The green tire 9 is molded by combining various rubber materials. The green tire 9 in the unvulcanized state is flexible and easily deformed. In particular, the green tire 9 molded by the ribbon winding method keeps a high temperature state for a while after molding, and is easily deformed by the weight of the tire or an external factor. The ribbon winding method is a method in which an unvulcanized rubber ribbon is continuously supplied to a rotary support such as a molding drum, and the rubber ribbon is spirally wound to form a rubber member having a desired shape.

成型されたグリーンタイヤ９は、加硫機に供給されるまでの間、図２〜５に示すグリーンタイヤ保持装置１（以下、単に「保持装置１」と呼ぶことがある）によって一時的に保持される。保持装置１は、布材２と、その布材２を水平に広げた状態で支持する支持部材３とを備える。図６及び７に示すように、布材２には、グリーンタイヤ９がタイヤ軸方向を上下に向けた横置きの状態で載置される。布材２は、下方を向いたグリーンタイヤ９のビード部９１が嵌入される嵌入穴２１と、その嵌入穴２１の周縁で厚み方向（上下方向）に貫通して形成されたスリット２２とを有する。 The molded green tire 9 is temporarily held by the green tire holding device 1 (hereinafter, may be simply referred to as “holding device 1”) shown in FIGS. 2 to 5 until it is supplied to the vulcanizer. Will be done. The holding device 1 includes a cloth material 2 and a support member 3 that supports the cloth material 2 in a horizontally spread state. As shown in FIGS. 6 and 7, the green tire 9 is placed on the cloth material 2 in a horizontal position with the tire axial direction facing up and down. The cloth material 2 has a fitting hole 21 into which the bead portion 91 of the green tire 9 facing downward is fitted, and a slit 22 formed through the peripheral edge of the fitting hole 21 in the thickness direction (vertical direction). ..

この保持装置１によれば、下方を向いたビード部９１が嵌入穴２１に嵌入されることにより、布材２に対するグリーンタイヤ９の大凡の位置が定まる。その際、嵌入穴２１の周囲に沿った周縁部２３（図４参照）がビード部９１の外面に接触しうる。また、スリット２２が形成されていることにより、図７のように嵌入穴２１の周縁部２３がグリーンタイヤ９に合わせて下方に撓み、タイヤのサイズや品種に応じてビード部９１の外径Ｄ１が変動した場合でも適宜に対応できる。その結果、横置きの状態で保持したグリーンタイヤ９の変形や外傷の発生が抑制される。 According to the holding device 1, the downwardly facing bead portion 91 is fitted into the fitting hole 21, so that the approximate position of the green tire 9 with respect to the cloth material 2 is determined. At that time, the peripheral edge portion 23 (see FIG. 4) along the periphery of the fitting hole 21 may come into contact with the outer surface of the bead portion 91. Further, since the slit 22 is formed, the peripheral edge portion 23 of the fitting hole 21 bends downward in accordance with the green tire 9 as shown in FIG. 7, and the outer diameter D1 of the bead portion 91 depends on the tire size and type. Can be dealt with appropriately even if As a result, deformation and trauma of the green tire 9 held in the horizontal position are suppressed.

布材２は、その水平方向の寸法に比べて厚みｔが小さいシート状に形成されている。布材２の厚みｔは、例えば２．０〜６．０ｍｍである。布材２は、円形状に形成されているが、これに限られず、例えば矩形状であってもよい。布材２には、キャンバスが好ましく用いられる。キャンバスとしては、例えば、天然ゴムやスチレンブタジエンゴムなどのゴム材、ポリエステルコードなどの有機繊維コード及び綿帆布の複合物が用いられる。但し、上述のようにしてグリーンタイヤ９を保持しうるものである限り、布材２の材質は特に限定されない。 The cloth material 2 is formed in the form of a sheet having a thickness t smaller than its horizontal dimension. The thickness t of the cloth material 2 is, for example, 2.0 to 6.0 mm. The cloth material 2 is formed in a circular shape, but is not limited to this, and may be, for example, a rectangular shape. Canvas is preferably used as the cloth material 2. As the canvas, for example, a rubber material such as natural rubber or styrene-butadiene rubber, an organic fiber cord such as polyester cord, and a composite of cotton canvas are used. However, the material of the cloth material 2 is not particularly limited as long as the green tire 9 can be held as described above.

本実施形態では、嵌入穴２１が円形状に形成されている。嵌入穴２１の直径Ｄ２はビード部９１の外径Ｄ１よりも大きいが、これに限られない。スリット２２は、その嵌入穴２１の周縁からタイヤ径方向外側に延びる。スリット２２の長さは、例えば５０〜１５０ｍｍに設定される。周縁部２３を適度に撓ませる観点から、スリット２２の長さは、その長さ方向に沿って測定される嵌入穴２１の大きさ（即ち、直径Ｄ２）の１０％以上であることが好ましい。また、グリーンタイヤ９を適切に保持できるよう、スリット２２の長さは、直径Ｄ２の２５％以下であることが好ましい。 In the present embodiment, the fitting hole 21 is formed in a circular shape. The diameter D2 of the fitting hole 21 is larger than the outer diameter D1 of the bead portion 91, but is not limited to this. The slit 22 extends outward in the tire radial direction from the peripheral edge of the fitting hole 21. The length of the slit 22 is set to, for example, 50 to 150 mm. From the viewpoint of appropriately bending the peripheral edge portion 23, the length of the slit 22 is preferably 10% or more of the size of the fitting hole 21 (that is, the diameter D2) measured along the length direction thereof. Further, the length of the slit 22 is preferably 25% or less of the diameter D2 so that the green tire 9 can be appropriately held.

布材２には、複数本のスリット２２がタイヤ周方向に略等間隔で配置されていることが好ましい。周縁部２３はスリット２２によって複数の領域に区画され、その各々がグリーンタイヤ９の外面に沿って舌片状に垂れ下がるように撓む。周縁部２３を適度に且つ均等に撓ませやすくするうえで、放射状に配置されたスリット２２の本数は四本以上が好ましく、六本以上がより好ましく、八本以上が更に好ましい。また、周縁部２３が過度に軟弱にならないよう、スリット２２の本数は十八本以下が好ましく、十二本以下がより好ましい。 It is preferable that a plurality of slits 22 are arranged at substantially equal intervals in the tire circumferential direction in the cloth material 2. The peripheral edge portion 23 is divided into a plurality of regions by slits 22, and each of them bends along the outer surface of the green tire 9 so as to hang down like a tongue piece. In order to make it easier to flex the peripheral edge portion 23 appropriately and evenly, the number of the slits 22 arranged radially is preferably four or more, more preferably six or more, and further preferably eight or more. Further, the number of slits 22 is preferably 18 or less, and more preferably 12 or less so that the peripheral edge portion 23 is not excessively soft.

支持部材３は、環状の固定枠３１によって布材２の外縁部を固定し、布材２を適度に張った状態で支持している。固定枠３１は、円形状に形成されているが、これに限られず、例えば矩形状であってもよい。支持部材３は、例えば金属で形成されている。この保持装置１では、複数（本実施形態では三つ）の支持部材３が上下に並べて配置されている。説明の都合上、これらを支持部材３ａ，３ｂ，３ｃと呼んで区別する。支持部材３ａ〜３ｃは、それぞれ機体フレーム４に搭載されている。機体フレーム４は、金属製の管材または柱材で形成されている。 The support member 3 fixes the outer edge portion of the cloth material 2 by an annular fixing frame 31, and supports the cloth material 2 in an appropriately stretched state. The fixed frame 31 is formed in a circular shape, but is not limited to this, and may be, for example, a rectangular shape. The support member 3 is made of, for example, metal. In this holding device 1, a plurality of (three in this embodiment) support members 3 are arranged one above the other. For convenience of explanation, these are referred to as support members 3a, 3b, 3c to distinguish them. The support members 3a to 3c are mounted on the airframe frame 4, respectively. The airframe frame 4 is made of a metal pipe material or a pillar material.

機体フレーム４は、平面視で矩形状をなす台枠部４１と、台枠部４１から立ち上がった立設部４２とを有する。台枠部４１には、最も下方に位置する支持部材３ｃが取り付けられている。立設部４２には、残りの支持部材３ａ，３ｂが、それぞれアーム３２とベアリングユニット３３を介して取り付けられている。ベアリングユニット３３は、水平方向に延びた回動軸３３ａを備え、その回動軸３２ａの軸線周りに支持部材３ａ，３ｂを回動できる。よって、本実施形態では、複数の支持部材３のうち、相対的に上方に位置する支持部材３ａ，３ｂが上下回動自在に構成されている。 The airframe frame 4 has an underframe portion 41 having a rectangular shape in a plan view, and an upright portion 42 rising from the underframe portion 41. A support member 3c located at the lowermost position is attached to the underframe portion 41. The remaining support members 3a and 3b are attached to the upright portion 42 via the arm 32 and the bearing unit 33, respectively. The bearing unit 33 includes a rotating shaft 33a extending in the horizontal direction, and the support members 3a and 3b can be rotated around the axis of the rotating shaft 32a. Therefore, in the present embodiment, among the plurality of support members 3, the support members 3a and 3b located relatively upward are configured to be vertically rotatable.

図２に破線で示したように支持部材３ａを上方に回動させることで、その下方に位置する支持部材３ｂの上方が開放され、グリーンタイヤ９の出し入れが容易になる。支持部材３ａは、グリーンタイヤ９が載置される水平姿勢と、上方に回動した開放姿勢との間で変位する。保持装置１は、支持部材３ａを開放姿勢に向けて付勢する付勢部材としてのガススプリング３４と、支持部材３ａを水平姿勢でロックする留め具（図示せず）とを有する。留め具を操作してロックを解除すると、ガススプリング３４の付勢力によって支持部材３ａが上方に回動する。支持部材３ｂも、これと同様に構成されている。 By rotating the support member 3a upward as shown by the broken line in FIG. 2, the upper part of the support member 3b located below the support member 3a is opened, and the green tire 9 can be easily taken in and out. The support member 3a is displaced between the horizontal posture in which the green tire 9 is placed and the open posture in which the green tire 9 is rotated upward. The holding device 1 has a gas spring 34 as an urging member that urges the support member 3a toward the open posture, and a fastener (not shown) that locks the support member 3a in the horizontal posture. When the fastener is operated to release the lock, the support member 3a is rotated upward by the urging force of the gas spring 34. The support member 3b is also configured in the same manner.

本実施形態の保持装置１は、キャスター５を有し、運搬台車として構成されている。キャスター５は、機体フレーム４の下部に設けられている。これにより、成型後のグリーンタイヤ９を保持装置１によって加硫機まで運搬し、グリーンタイヤ成型工程から加硫工程へ円滑に移行できる。また、保持装置１には、作業者が把持するための把手６が設けられている。牽引車、または牽引車に牽引される別の保持装置と連結するための連結具を立設部４２に設けて、保持装置１を牽引して移動できるように構成することも可能である。 The holding device 1 of the present embodiment has casters 5 and is configured as a transport carriage. The casters 5 are provided at the lower part of the airframe frame 4. As a result, the molded green tire 9 can be transported to the vulcanizer by the holding device 1 and smoothly transition from the green tire molding process to the vulcanization process. Further, the holding device 1 is provided with a handle 6 for the operator to grip. It is also possible to provide a connecting tool for connecting to the towing vehicle or another holding device towed by the towing vehicle in the upright portion 42 so that the holding device 1 can be towed and moved.

本実施形態では、保持装置１が、上下に並べて配置された三段の支持部材３の各々に一本のグリーンタイヤ９を載置できる構成、言わば、三本のグリーンタイヤ９を積載可能な「三段×一本」の構成を有する。変形例として、複数の固定枠３１を水平方向に並べて配置し、一つの支持部材３で複数本のグリーンタイヤ９を保持できるように構成してもよい。その場合、保持装置は、例えば、六本のグリーンタイヤを積載可能な「三段×二本」の構成にしたり、十二本のグリーンタイヤを積載可能な「四段×三本」の構成にしたりすることが考えられる。 In the present embodiment, the holding device 1 can mount one green tire 9 on each of the three-stage support members 3 arranged one above the other, so to speak, three green tires 9 can be loaded. It has a structure of "three steps x one". As a modification, a plurality of fixed frames 31 may be arranged side by side in the horizontal direction so that one support member 3 can hold a plurality of green tires 9. In that case, the holding device has, for example, a "three-stage x two" configuration capable of loading six green tires, or a "four-stage x three" configuration capable of loading twelve green tires. It is possible that it will happen.

本発明は上述した実施形態に何ら限定されるものではなく、本発明の趣旨を逸脱しない範囲内で種々の改良変更が可能である。 The present invention is not limited to the above-described embodiment, and various improvements and changes can be made without departing from the spirit of the present invention.
