Description
この発明は、バンド成形ドラム上で成形された円筒形状をなすタイヤ成形用のバンドを該バンド成形ドラムと同軸上に位置するシェーピングドラムに搬送し、該バンドをシェーピングドラムに搬送した後にシェーピングドラムから退去するバンド搬送装置に関するものである。
In the present invention, a cylindrical tire forming band formed on a band forming drum is transferred to a shaping drum positioned coaxially with the band forming drum, and the band is transferred from the shaping drum to the shaping drum. The present invention relates to a retreating band conveyance device.
タイヤの成形にあたっては、バンド成形ドラム上にてタイヤ構成部材のインナーライナ、カーカス、ビード等を組み立てて円筒形状のバンドを形成し、このバンドをバンド搬送装置によりシェーピングドラムに搬送し、シェーピングドラムでバンドを所定形状にシェーピングするとともにベルト・トレッド組立体をカーカスに接着させる。そして空になったバンド搬送装置はシェーピングドラムから退去させるが、このときシェーピングドラムにセットしたバンドを傷つけたり位置ずれを生じさせたりしないために該バンドとの干渉を回避しなければならない。
When forming a tire, an inner liner, a carcass, a bead, etc., of tire components are assembled on a band forming drum to form a cylindrical band, and this band is conveyed to a shaping drum by a band conveying device. The band is shaped into a predetermined shape and the belt / tread assembly is bonded to the carcass. Then, the emptied band transport device is moved away from the shaping drum. At this time, the band set on the shaping drum is not damaged, and the positional deviation is not caused. Therefore, interference with the band must be avoided.
このため、特許文献1には、バンドをシェーピングドラムへ搬送するときには、円環状の支持リングに配置された複数のホルダをリンク機構を介して径方向内側に同期して移動させてバンドを保持するようにし、シェーピングドラムから退去するときには、上記複数のホルダを径方向外側に後退させることにより、シェーピングドラムにセットしたバンドとの干渉を避けるようにしたバンド・ビード供給機が提案されている。
For this reason, in Patent Document 1, when a band is transported to a shaping drum, a plurality of holders arranged on an annular support ring are moved synchronously radially inward via a link mechanism to hold the band. Thus, when moving away from the shaping drum, a band bead feeder has been proposed in which the plurality of holders are retracted radially outward so as to avoid interference with the band set on the shaping drum.
また、特許文献2には、図8(a)に示すように、左右で対をなすトランスファシュー100a、100bを、左側のトランスファシュー100aの脚部と右側のトランスファシュー100bの脚部とを左右方向にシリンダ等により移動させることによって開閉可能とし、シェーピングドラムから退去するときには、左右のトランスファシュー100a、100bを開放することにより、シェーピングドラムにセットしたバンド(ビードが既にセットされている場合はビード)との干渉を避けるようにしたバンドトランスファが提案されている。
Further, in Patent Document 2, as shown in FIG. 8A, left and right transfer shoes 100a and 100b are paired with left and right transfer shoes 100a and right transfer shoes 100b with right and left legs. The band can be opened and closed by moving it in the direction by a cylinder or the like, and when leaving the shaping drum, the left and right transfer shoes 100a, 100b are opened to set the band set on the shaping drum (if the bead is already set, the bead ) Has been proposed that avoids interference with).
しかしながら、特許文献1に記載のバンド・ビード供給機は、支持リングに配置されたホルダの後退動作のみによってシェーピングドラムにセットしたバンドとの干渉を避けるものであるので、各ホルダの後退代を大きく確保するために支持リングを大きく(大径に)形成しなければならず、装置の大型化および重量増しが避けられないものとなっている。
However, since the band bead feeder described in Patent Document 1 avoids interference with the band set on the shaping drum only by the retraction operation of the holder arranged on the support ring, the retreat margin of each holder is greatly increased. In order to ensure this, the support ring must be formed large (with a large diameter), and the size and weight of the apparatus cannot be avoided.
また、特許文献2に記載のバンドトランスファは、左右のトランスファシュー100a、100bが左右方向のみに移動するものであるので、図8(a)に示すように、シェーピングドラムにセットしたバンド(ビードが既にセットされている場合はビード)との干渉を避けるにあたって、左右のトランスファシュー100a、100bを開放させた際に側方へのはみ出し量Δdが大きくなり、設置スペースが増大してしまう。また、このバンドトランスファでは、バンドの保持姿勢において、左右のトランスファシュー100a、100bの間に隙間を有しバンドの上部および下部がこれらのトランスファシュー100a、100bによって保持されないので、トランスファシュー100a、100bによってバンドを保持した際にバンドが歪んだり、シェーピングドラムにセットした際にバンドの軸心とシェーピングドラムの軸心に芯ずれが生じたりするおそれがある。これを防止するために、図8(b)に対比して説明するように、左右のトランスファシュー100a、100bの間に隙間を設けず、バンドの全周をトランスファシュー100a、100bで保持するようにした場合には、トランスファシュー100a、100bを開放した際の側方へのはみ出し量Δdがさらに大きくなってしまう。
In the band transfer described in Patent Document 2, since the left and right transfer shoes 100a and 100b move only in the left and right direction, as shown in FIG. When the left and right transfer shoes 100a and 100b are opened in order to avoid interference with the beads) when set, the amount of protrusion Δd to the side becomes large, and the installation space increases. In this band transfer, in the holding posture of the band, there is a gap between the left and right transfer shoes 100a, 100b, and the upper and lower portions of the band are not held by these transfer shoes 100a, 100b. Therefore, there is a risk that the band may be distorted when the band is held, or that the center axis of the band and the axis of the shaping drum may be misaligned when set on the shaping drum. In order to prevent this, as described in comparison with FIG. 8B, no gap is provided between the left and right transfer shoes 100a and 100b, and the entire circumference of the band is held by the transfer shoes 100a and 100b. In this case, the amount of protrusion Δd to the side when the transfer shoes 100a and 100b are opened further increases.
それゆえこの発明は、シェーピングドラムへのバンドのセット精度を良好に保ちつつも省スペース化を実現でき、しかも小型かつ軽量なバンド搬送装置を提供することを目的とする。
Therefore, an object of the present invention is to provide a small and lightweight band transport device that can realize space saving while maintaining good accuracy of setting a band on a shaping drum.
この発明は上記課題を解決するためになされたものであり、この発明のバンド搬送装置は、バンド成形ドラム上で成形された円筒形状をなすタイヤ成形用のバンドを該バンド成形ドラムと同軸上に位置するシェーピングドラムに搬送し、バンドをシェーピングドラムに搬送した後にシェーピングドラムから退去するバンド搬送装置において、上記バンド成形ドラムと上記シェーピングドラムとの間で軸心方向に沿って移動する搬送基台と、上記搬送基台に対して近接方向および離間方向に移動可能に設けられ、周方向に二以上の枠片に分割されて上記搬送基台と向き合う側とは反対側にて開閉可能な環状の枠体と、上記搬送基台と上記枠体との間を連結するとともに該枠体を搬送基台に対して近接方向および離間方向に移動させる枠体移動手段と、上記枠体を上記搬送基台と向き合う側とは反対側にて開閉させる開閉手段と、上記枠体に周方向に略均等に配置され、上記枠体よりも径方向内側にて上記バンドを保持する進出位置と該進出位置よりも径方向外側に後退した後退位置との間で径方向に沿って進退移動可能な複数の保持具と、各保持具同士を作動連結して該保持具を上記進出位置と上記後退位置との間で同期して進退移動させるリンク機構と、を備え、上記シェーピングドラムからの退去時に、上記枠体移動手段が上記枠体を上記近接方向に移動させるとともに上記開閉手段が上記枠体の上記反対側を開放して、シェーピングドラムに搬送されたバンドとの干渉を回避することを特徴とするものである。
SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and the band conveying device of the present invention is configured such that a cylindrical tire forming band formed on a band forming drum is coaxial with the band forming drum. In a band transport device that transports to a shaping drum that is positioned, moves the band to the shaping drum, and then retreats from the shaping drum, a transport base that moves along the axial direction between the band forming drum and the shaping drum; An annular ring that is provided so as to be movable in the proximity direction and the separation direction with respect to the transport base, and that can be opened and closed on the side opposite to the side facing the transport base by being divided into two or more frame pieces in the circumferential direction. A frame body movement for connecting the frame body between the conveyance base and the frame body and moving the frame body in a proximity direction and a separation direction with respect to the conveyance base A step, opening / closing means for opening and closing the frame on the side opposite to the side facing the transport base, and a substantially equal circumferential arrangement on the frame, the inner side in the radial direction of the frame A plurality of holders that can move forward and backward along the radial direction between an advance position that holds the band and a retract position that is retracted radially outward from the advance position, and each holder is operatively connected to hold the band. A link mechanism for moving the tool forward and backward in synchronization between the advance position and the reverse position, and the frame body moving means moves the frame body in the proximity direction when the tool moves out of the shaping drum. The opening / closing means opens the opposite side of the frame to avoid interference with the band conveyed to the shaping drum.
かかるバンド搬送装置にあっては、バンドをシェーピングドラムへ搬送するときには、枠体に支持された保持具をリンク機構を介して径方向内側に同期して移動させ、保持具にバンドを保持させる。一方、シェーピングドラムから退去するときには、保持具を径方向外側に後退させた後に、枠体移動手段を作動させ枠体を搬送基台側に遠ざけるとともに開閉手段を作動させ枠体の、搬送基台とは反対側を開放させることにより、枠体を側方へ開放しつつ搬送基台側へ向けて移動させる。これにより、バンド搬送装置とシェーピングドラムに搬送されたバンドとの干渉が回避される。
In such a band transport device, when the band is transported to the shaping drum, the holder supported by the frame is moved synchronously radially inward via the link mechanism, and the band is held by the holder. On the other hand, when retreating from the shaping drum, after the holder is retracted radially outward, the frame body moving means is operated to move the frame body away from the conveyance base and the opening / closing means is operated to operate the frame base. By opening the opposite side, the frame is moved toward the transport base while being opened sideways. Thereby, interference with the band conveyed by the band conveying apparatus and the shaping drum is avoided.

In addition, the frame body is divided into two or more frame pieces, and it is configured to be movable toward the transport base side while opening to the side, so the amount of protrusion to the side when the band transport device moves out is greatly increased. It can be reduced and space saving can be realized. Moreover, since the interference with the band is avoided by opening the frame in addition to the backward movement of the holder, the backward movement of the holder can be reduced, which also contributes to space saving and downsizing and Weight reduction can be achieved.

And a pinion gear 16 to which a rotational force from a motor 15 as a driving means for driving the conveyance base is transmitted. The pinion gear 16 extends along the axis X of the band forming drum 2 and the shaping drum 3. The carrier base 5 moves between the band forming drum 2 and the shaping drum 3 along the axis X by meshing with the laid rack gear 17.
枠体移動手段として設けられたシリンダ7は、搬送基台5のベースプレート14に垂直に固定され、空圧または油圧により駆動されるものであるが、これに代えてねじ機構を用いて枠体6を上下方向に移動するよう構成してもよい。なお、シリンダ7による枠体7の上下移動は、枠体6の下部から下方に延びるガイド軸10aと該ガイド軸10aを摺動可能に案内する軸受10bとにより案内される。
The cylinder 7 provided as a frame moving means is fixed perpendicularly to the base plate 14 of the transport base 5 and is driven by air pressure or hydraulic pressure. Instead of this, the frame 6 is used by using a screw mechanism. You may comprise so that it may move to an up-down direction. The vertical movement of the frame body 7 by the cylinder 7 is guided by a guide shaft 10a extending downward from the lower portion of the frame body 6 and a bearing 10b for guiding the guide shaft 10a so as to be slidable.
枠体6は、ここでは全体として円環形状をなし、周方向に分割された三つの円弧形状の枠片6a、6b、6cからなる。これらの枠片6a、6b、6cのうち、第一の枠片6aは枠体移動手段としてのシリンダ7のピストンロッド7aに連結されており、第二および第三の枠片6b、6cは、各々の基端部にて第一の枠片6aの各端部にヒンジ19を介して回動可能に軸支されている。よって、枠体6は、シリンダ7の作動により上下方向に移動する。
Here, the frame body 6 has an annular shape as a whole, and includes three arc-shaped frame pieces 6a, 6b, and 6c divided in the circumferential direction. Of these frame pieces 6a, 6b and 6c, the first frame piece 6a is connected to the piston rod 7a of the cylinder 7 as the frame body moving means, and the second and third frame pieces 6b and 6c are Each base end portion is pivotally supported via a hinge 19 at each end portion of the first frame piece 6a. Therefore, the frame body 6 moves up and down by the operation of the cylinder 7.
枠体6の上側を開閉させる開閉手段としてのシリンダ8は各々、ヒンジ19を跨ぐように第一の枠片6aと第二および第三の枠片6b、6cとの間を連結し、各々のシリンダ8の基端部は第一の枠片6aに連結され、各々のシリンダ8のピストンロッド8aの先端部は第二および第三の枠片6b、6cに連結されている。よって、シリンダ8の作動により第二の枠片6bおよび第三の枠片6cがヒンジ19を基点に回動して、枠体6の上側が開閉する。なお、開閉手段としてはラック・ピニオン等の歯車機構を用いてもよい。
The cylinders 8 as opening / closing means for opening and closing the upper side of the frame body 6 respectively connect the first frame piece 6a and the second and third frame pieces 6b and 6c so as to straddle the hinge 19, The base end portion of the cylinder 8 is connected to the first frame piece 6a, and the tip end portion of the piston rod 8a of each cylinder 8 is connected to the second and third frame pieces 6b and 6c. Therefore, the second frame piece 6b and the third frame piece 6c are rotated about the hinge 19 by the operation of the cylinder 8, and the upper side of the frame body 6 is opened and closed. A gear mechanism such as a rack and pinion may be used as the opening / closing means.
保持具9はここでは六つ設けられ、第一、第二および第三の枠片6a、6b、6cの各々に一つ以上(ここでは二つずつ)配置されている。図3に示すように、各保持具9は、枠片6a、6b、6cに形成されたアリ溝20に嵌合する突出部21をもつ移動ブロック22と、移動ブロック22の下端(径方向内端)に一体に設けられ、バンドCBの内周面または外周面(ここでは内周面)に沿った形状を有する円弧形状の当接板23とを有する。当接板23には、軽量化のために複数の開口23aを設けてもよい。また、保持具9の移動ブロック22には、後述するベルクランク26のクランクピン26aを案内する長孔形状のガイド溝24が形成されている。
Six holders 9 are provided here, and one or more (two in this case) are arranged on each of the first, second and third frame pieces 6a, 6b and 6c. As shown in FIG. 3, each holder 9 includes a moving block 22 having a protrusion 21 that fits into a dovetail groove 20 formed in the frame pieces 6 a, 6 b, and 6 c, and a lower end (in the radial direction) of the moving block 22. And an arcuate contact plate 23 having a shape along the inner or outer peripheral surface (here, the inner peripheral surface) of the band CB. The contact plate 23 may be provided with a plurality of openings 23a for weight reduction. The moving block 22 of the holder 9 is formed with a long hole-shaped guide groove 24 for guiding a crank pin 26a of a bell crank 26 described later.
図2に示すように、リンク機構11は、リンク機構11を駆動する駆動部25と、駆動部25による回転運動を、直線運動すなわち保持具9の径方向に沿った進退運動に変換するベルクランク26と、各ベルクランク26同士をつないで駆動部25からの回転運動を伝達するリンクアーム27とを有してなる。ヒンジ19の両側に位置するベルクランク26同士をつなぐリンクアーム27は、互いに回動自在に連結された二以上(ここでは二つ)の分割アーム27a、27bからなる。駆動部25は、第一の枠片6aの下部にブラケット29を介して取り付けられたシリンダ30と、シリンダ30のピストンロッド30aに連結され上下に直線運動するラックギア31と、ラックギア31からの直線運動により左右に回転するピニオンギア32とからなる。ピニオンギア32には、駆動部25に最も近い保持具9を進退移動させるベルクランク26が固定されている。また、全てのベルクランク26は、保持具9の移動ブロック22に形成されたガイド溝24内を摺動するクランクピン26aを有している。よって、リンク機構11のシリンダ30を作動すると駆動部25に最も近いベルクランク26が回転し、その回転力がリンクアーム27を介して隣りに位置するベルクランク26に順次伝達され、これにより、全ての保持具9は同期して径方向に沿って進退移動する。
As shown in FIG. 2, the link mechanism 11 includes a drive unit 25 that drives the link mechanism 11, and a bell crank that converts the rotational motion by the drive unit 25 into linear motion, that is, forward / backward motion along the radial direction of the holder 9. 26 and a link arm 27 that connects the bell cranks 26 to each other and transmits the rotational motion from the drive unit 25. The link arm 27 that connects the bell cranks 26 located on both sides of the hinge 19 includes two or more (here, two) split arms 27a and 27b that are rotatably connected to each other. The drive unit 25 includes a cylinder 30 attached to the lower portion of the first frame piece 6a via a bracket 29, a rack gear 31 connected to the piston rod 30a of the cylinder 30 and moving linearly up and down, and linear movement from the rack gear 31. And a pinion gear 32 that rotates left and right. A bell crank 26 is fixed to the pinion gear 32 for moving the holder 9 closest to the drive unit 25 forward and backward. All the bell cranks 26 have a crank pin 26 a that slides in a guide groove 24 formed in the moving block 22 of the holder 9. Therefore, when the cylinder 30 of the link mechanism 11 is operated, the bell crank 26 closest to the drive unit 25 is rotated, and the rotational force is sequentially transmitted to the adjacent bell crank 26 via the link arm 27. The holder 9 is moved forward and backward along the radial direction in synchronization.
またこのバンド搬送装置1は、ヒンジ19の両側に位置する保持具9、すなわち第二の枠片6bおよび第三の枠片6cに配置された保持具9のうち最も第一の枠片6a寄りに位置する保持具9と第一の枠片6aに配置された保持具9うち最も第二および第三の枠片6b、6c寄りに位置する保持具9との間の、リンク機構11を介した連結を、択一的に作動連結状態と該作動連結を解除した非作動連結状態とに切替える切替え手段としてのシリンダ34を備えている。シリンダ34は、ヒンジ19の両側に位置するベルクランク34をつなぐ二つの分割アーム27a、27bの相対回動を択一的に許可および停止するものである。具体的には、二つの分割アーム27a、27bのうち一方(ここでは上側に位置する分割アーム27a)の端部に、他方の分割アーム27bに取り付けられたシリンダ34のピストンロッド34aが挿入されるための穴27a1(図5参照)が設けており、シリンダ34のピストンロッド34aを突出させるとともに当該穴27a1に挿入すると分割アーム27a、27bが相互に固定され、反対にシリンダ34のピストンロッド34aを引っ込めると、二つの分割アーム27a、27bが自由に相対回動可能となる。なお、シリンダ34に代えて電磁石(図示省略)を用い、電磁石への通電のオフ・オンにて二つの分割アーム同士の相対回動を許可および停止可能に構成してもよい。
Further, the band conveying device 1 is provided near the first frame piece 6a among the holders 9 located on both sides of the hinge 19, that is, the holders 9 arranged on the second frame piece 6b and the third frame piece 6c. Via the link mechanism 11 between the holder 9 located at the first frame piece 6a and the holder 9 located closest to the second and third frame pieces 6b, 6c. A cylinder 34 is provided as switching means for selectively switching the connection between an operation connection state and a non-operation connection state in which the operation connection is released. The cylinder 34 selectively permits and stops the relative rotation of the two split arms 27 a and 27 b that connect the bell cranks 34 located on both sides of the hinge 19. Specifically, the piston rod 34a of the cylinder 34 attached to the other divided arm 27b is inserted into the end of one of the two divided arms 27a and 27b (here, the divided arm 27a positioned on the upper side). Hole 27a 1 (see FIG. 5) is provided, and when the piston rod 34a of the cylinder 34 protrudes and is inserted into the hole 27a 1 , the split arms 27a and 27b are fixed to each other, and conversely, the piston rod of the cylinder 34 When 34a is retracted, the two split arms 27a and 27b can freely rotate relative to each other. Note that an electromagnet (not shown) may be used in place of the cylinder 34 so that the relative rotation between the two divided arms can be permitted and stopped by turning on and off the electromagnet.
さらにこのバンド搬送装置1は、ヒンジ19よりも上方に位置する第二および第三の枠片6b、6cに配置された保持具9を任意の後退位置、ここでは最終後退位置(保持具が最も径方向外側に後退した位置)にてロックするロック手段としてのシリンダ36を備えている。具体的には、シリンダ36は第二の枠体6bおよび第三の6cにそれぞれ固定されている。また、第二および第三の枠片6b、6cに配置された保持具9のうち最もヒンジに近い保持具9には、シリンダ36のピストンロッド36aが挿入される穴37aをもつ固定プレート37が設けられている。固定プレート37とシリンダ36とは、保持具9が最終後退位置に後退した状態にてそれらの穴37aおよびピストンロッド36aが一致するよう予め位置決めされている。よって、保持具9の最終後退位置にてシリンダ36のピストンロッド36aを突出させるとともに保持具9の固定プレート37の穴37aに挿入することにより、保持具9は枠体6a、6bに対して最終後退位置に位置固定される。なお、シリンダ36に代えて電磁石(図示省略)を用い、電磁石への通電のオンオフにて保持具9を枠体6b、6cに対して位置固定およびその解除を行うように構成してもよい。
Further, the band transport device 1 allows the holder 9 disposed on the second and third frame pieces 6b and 6c located above the hinge 19 to be in an arbitrary retracted position, here the final retracted position (the holder is the most). A cylinder 36 is provided as locking means for locking at a position retracted radially outward). Specifically, the cylinder 36 is fixed to the second frame 6b and the third 6c, respectively. Of the holders 9 disposed on the second and third frame pieces 6b and 6c, the holder 9 closest to the hinge has a fixing plate 37 having a hole 37a into which the piston rod 36a of the cylinder 36 is inserted. Is provided. The fixing plate 37 and the cylinder 36 are positioned in advance so that the holes 37a and the piston rod 36a coincide with each other when the holder 9 is retracted to the final retracted position. Therefore, the retainer 9 is finally moved with respect to the frames 6a and 6b by causing the piston rod 36a of the cylinder 36 to protrude at the final retracted position of the retainer 9 and inserting it into the hole 37a of the fixing plate 37 of the retainer 9. The position is fixed at the retracted position. Note that an electromagnet (not shown) may be used in place of the cylinder 36, and the holder 9 may be fixed and released with respect to the frames 6b and 6c by turning on and off the energization of the electromagnet.
ところで、バンド搬送装置1により、搬送時にバンドCBの端部を保持する場合には、図1に示すビードセッター4によってバンドCBを補助的に保持することにより、より安定してバンドCBを搬送できるようになるが、ビードセッター4としては、バンド搬送装置1と同様に、シェーピングドラム3からの退去時にバンドCB(ビードBが配置されている場合にはビードB)との干渉を避け得るものが好ましく、以下にその一例を説明する。
By the way, when the band transport device 1 holds the end of the band CB during transport, the band CB can be transported more stably by supporting the band CB by the bead setter 4 shown in FIG. However, the bead setter 4 can avoid interference with the band CB (bead B when the bead B is disposed) when the bead setter 4 is withdrawn from the shaping drum 3, as with the band transfer device 1. Preferably, an example will be described below.
ビードセッター4は、バンド成形ドラム2上のバンドCBに対して、軸心X方向に所定の間隔を空けて一組のビードBを供給するものであり、図1に示すように、ビードBを保持および解放可能であるビード保持部材40と、ビード保持部材40を支持するとともにビード保持部材40を軸心Xに沿って可動に案内する搬送手段としての搬送基台41と、を備えてなる。なお、ビードセッターの搬送基台41は、バンド搬送装置1の搬送基台5とほぼ同様の構成であるので、同様の符号(「’」付き)を付してその説明を省略する。
The bead setter 4 supplies a set of beads B to the band CB on the band forming drum 2 at a predetermined interval in the axial center X direction. As shown in FIG. A bead holding member 40 that can be held and released, and a conveyance base 41 as a conveying means that supports the bead holding member 40 and movably guides the bead holding member 40 along the axis X are provided. The transport base 41 of the bead setter has substantially the same configuration as that of the transport base 5 of the band transport apparatus 1, and therefore, the same reference numerals (with “′”) are given and description thereof is omitted.
図6に代表して一方のビードセッター4を示すに、ビード保持部材40は、各々円弧形状を持ち互いに近接した状態(以下、「閉状態」という)にて協働して円環形状を形成する第一の弧状体40a、第二の弧状体40bおよび第三の弧状体40cを有している。また、各弧状体40a、40b、40cは、それぞれの内端部にビードBを吸着保持する多数の磁石42が円弧状に配設されている。
One bead setter 4 is shown as a representative of FIG. 6, and the bead holding members 40 each have an arc shape and cooperate to form an annular shape in a state of being close to each other (hereinafter referred to as “closed state”). A first arcuate body 40a, a second arcuate body 40b, and a third arcuate body 40c. In addition, each arcuate body 40a, 40b, 40c has a large number of magnets 42 that adsorb and hold the beads B at the inner end portions thereof.
第一の弧状体40aは、搬送基台41に対向して配置されるとともに、ベースプレート14’に垂直に固定された空圧または油圧により駆動される第一の弧状体駆動用の移動手段としてのシリンダ43のピストンロッド43aの先端に連結されている。これにより、第一の弧状体40aは、バンド成形ドラム2の軸心Xに直交する面内で径方向に沿って上下に移動自在に設けられている。第二および第三の弧状体40b、40cは、第一の弧状体40aの両側に互いに対向して配置されている。第二および第三の弧状体40b、40cは、上記閉状態にてそれらの上端が互いに接触する円周方向長さを有する。第二および第三の弧状体40a、40bの下端には、外側に向けて突出部40b1、40c1がそれぞれ連設されている。各突出部40b1、40c1の先端には、ベースプレート14’に立設されたブラケット44に固定された揺動支点としてのピン45に支持された揺動アーム46の一端がそれぞれ連結されている。揺動支点としてのピン45は、上記閉状態のビード保持部材40の径方向外側でかつ第二および第三の弧状体40b、40cとベースプレート14’との間に配置されている。各揺動アーム46の他端はそれぞれ、ベースプレート14’に略水平に取り付けられた空圧または油圧により駆動されるシリンダ47のピストンロッド47aの先端に連結されている。これらの揺動アーム46、ピン45およびシリンダ47は、第二および第三の弧状体40b、40cを揺動させる揺動手段を構成する。
The first arcuate body 40a is disposed opposite to the transport base 41, and serves as a moving means for driving the first arcuate body driven by air pressure or hydraulic pressure that is fixed perpendicularly to the base plate 14 '. The cylinder 43 is connected to the tip of the piston rod 43a. Thus, the first arcuate body 40a is provided so as to be movable up and down along the radial direction in a plane orthogonal to the axis X of the band forming drum 2. The second and third arcuate bodies 40b and 40c are arranged opposite to each other on both sides of the first arcuate body 40a. The second and third arcuate bodies 40b and 40c have circumferential lengths such that their upper ends are in contact with each other in the closed state. Protrusions 40b 1 and 40c 1 are connected to the lower ends of the second and third arcuate bodies 40a and 40b, respectively. One end of a swing arm 46 supported by a pin 45 as a swing fulcrum fixed to a bracket 44 erected on the base plate 14 ′ is connected to the tip of each protrusion 40 b 1 , 40 c 1 . . The pin 45 as the swing fulcrum is disposed on the radially outer side of the closed bead holding member 40 and between the second and third arcuate bodies 40b and 40c and the base plate 14 ′. The other end of each swing arm 46 is connected to the tip of a piston rod 47a of a cylinder 47 that is driven by air pressure or hydraulic pressure that is mounted substantially horizontally on the base plate 14 '. The swing arm 46, the pin 45, and the cylinder 47 constitute swing means for swinging the second and third arcuate bodies 40b and 40c.
よって、図6に仮想線および矢印で示すように、ベースプレート14’に垂直に取り付けられたシリンダ43のピストンロッド43aを引っ込めると、第一の弧状体40aが下方に移動し、シリンダ47のピストンロッド47aを引っ込めると、第二および第三の弧状体40b、40cが、揺動アーム46を介して軸心Xに直交する面内で外側に揺動展開する。なお、各弧状体40a、40b、40cを外側に展開した状態(図6に仮想線で示す状態であり、以下、「展開状態」という)にて、各弧状体40a、40b、40cの最内端P40a、P40b、P40cがそれぞれ、図6中に仮想線で示すバンドCB上のビードBの最外径位置Boutよりも径方向外側に位置するように、各シリンダ43、47のピストンロッド43a、47aの進退距離は設定されている。このビードセッター4を用いれば、シェーピングドラム3にセットしたバンドCB上のビードBとの干渉を回避する際の、ビード保持部材40の側方へのはみ出し量Δdを大幅に低減することができる。
Therefore, as shown by an imaginary line and an arrow in FIG. 6, when the piston rod 43a of the cylinder 43 attached perpendicularly to the base plate 14 ′ is retracted, the first arcuate body 40a moves downward, and the piston rod of the cylinder 47 When the 47 a is retracted, the second and third arcuate bodies 40 b and 40 c swing and expand outward in a plane perpendicular to the axis X through the swing arm 46. It should be noted that the innermost of each arcuate body 40a, 40b, 40c in a state where each arcuate body 40a, 40b, 40c is expanded outward (shown by a phantom line in FIG. 6, hereinafter referred to as “deployed state”). The ends P 40a , P 40b , and P 40c of the cylinders 43 and 47 are positioned so as to be located radially outside the outermost diameter position B out of the bead B on the band CB indicated by phantom lines in FIG. The advance / retreat distance of the piston rods 43a, 47a is set. If this bead setter 4 is used, the amount of protrusion Δd to the side of the bead holding member 40 when avoiding interference with the bead B on the band CB set on the shaping drum 3 can be greatly reduced.
次いで、これらのバンド搬送装置1およびビードセッター4を用いてバンド成形ドラム2上のバンドCBをシェーピングドラム3に搬送する方法について説明する。
Next, a method for conveying the band CB on the band forming drum 2 to the shaping drum 3 using the band conveying device 1 and the bead setter 4 will be described.
図1(a)では、バンド成形ドラム2にて、タイヤ構成部材のインナーライナやカーカス等が巻き付けられ円筒形状のバンドCBが形成され、そのバンドCB上にビードセッター1によってフィラーまたはスティフナー付のビードBがセットされている。
In FIG. 1 (a), an inner liner or a carcass of a tire component is wound around a band forming drum 2 to form a cylindrical band CB, and a bead with a filler or a stiffener is formed on the band CB by a bead setter 1. B is set.
バンド搬送装置1においては、先ず、図2に示すように、枠体移動手段としてのシリンダ7のピストンロッド7aおよび開閉手段としてのシリンダ8のピストンロッド8aを突出させて枠体6を閉じた状態にて、リンク機構11のシリンダ30のピストンロッド30aを引っ込めて保持具9の当接板23をバンドCBよりも径方向内側に位置させる。なお、リンク機構11のシリンダ30を作動する際には、予め切替え手段としてのシリンダ34のピストンロッド34aを分割アーム27aの穴27a1内に挿入し、全ての保持具9を作動連結しておくことが必要である。次いで、図1(b)に示すように、当接板23をバンドCBの端部内側に挿入し、リンク機構11を作動して全ての保持具9を同時に径方向外側に後退させ、保持具9によってバンドCBを保持する。このとき各保持具9は同期して径方向外側に移動するので、バンドCBは保持具9に均一に保持され、バンドCBの軸心がバンド成形ドラム2の軸心Xに対してずれたりバンドCBが変形したりすることがない。
In the band transfer device 1, first, as shown in FIG. 2, the piston rod 7a of the cylinder 7 as the frame body moving means and the piston rod 8a of the cylinder 8 as the opening and closing means are projected to close the frame body 6. Then, the piston rod 30a of the cylinder 30 of the link mechanism 11 is retracted, and the contact plate 23 of the holder 9 is positioned radially inward from the band CB. Incidentally, at the time of operation of the cylinder 30 of the link mechanism 11 inserts the piston rod 34a of the cylinder 34 as previously switching means into the hole 27a in one of the split arms 27a, keep operatively connected to all holders 9 It is necessary. Next, as shown in FIG. 1 (b), the contact plate 23 is inserted inside the end of the band CB, and the link mechanism 11 is operated to simultaneously retract all the holders 9 radially outward. 9 holds the band CB. At this time, since each holder 9 moves radially outward in synchronization, the band CB is uniformly held by the holder 9, and the axis of the band CB deviates from the axis X of the band forming drum 2. The CB is not deformed.
次いで、図1(c)に示すように、バンド搬送装置1およびビードセッター4をシェーピングドラム3まで移動させ、バンドCBをシェーピングドラム3にセットする。
Next, as shown in FIG. 1 (c), the band conveying device 1 and the bead setter 4 are moved to the shaping drum 3, and the band CB is set on the shaping drum 3.
次いで、バンド搬送装置1およびビードセッター4をシェーピングドラム3から退去させるが、バンド搬送装置1をシェーピングドラム3から退去させる際には、図1(d)に示すように、リンク機構11を作動して保持具9を一旦径方向内側に移動させることにより保持具9によるバンドCBの保持を解除した後に、図3(b)および図4に示すように、保持具9を径方向外側に移動させるとともに、ロック手段としてのシリンダ36により保持具9を最終後退位置にて枠片6b、6cに対して固定する。そして、枠体移動手段としてのシリンダ7のピストンロッド7aを引っ込めて枠体6を下方に移動させるとともに、開閉手段としてのシリンダ8のピストンロッド8aを引っ込めて第二および第三の枠片6b、6cをヒンジ19を基点に側方に展開して枠体6の上側を開放した状態にて、図1(e)に示すように、バンド搬送装置1をシェーピングドラム3から退去させる。これにより、枠体6の最内端P6は、セットしたバンドCB上のビードBの最外径位置Boutよりも径方向外側に位置するため、バンド搬送装置1の退去時にバンド搬送装置1とバンドCB上のビードBとが干渉することがない。なお、第二および第三の枠片6b、6cをヒンジ19を基点に回動させる際には、予め切替え手段としてのシリンダ34のピストンロッド34aを引っ込めて分割アーム27a、27b同士が自由に回動できるようにしておく必要がある。
Next, the band transport device 1 and the bead setter 4 are withdrawn from the shaping drum 3. When the band transport device 1 is withdrawn from the shaping drum 3, the link mechanism 11 is operated as shown in FIG. Then, the holding tool 9 is once moved radially inward to release the holding of the band CB by the holding tool 9, and then the holding tool 9 is moved radially outward as shown in FIGS. At the same time, the holder 9 is fixed to the frame pieces 6b and 6c at the final retracted position by the cylinder 36 as a locking means. Then, the piston rod 7a of the cylinder 7 as the frame body moving means is retracted to move the frame body 6 downward, and the piston rod 8a of the cylinder 8 as the opening / closing means is retracted to retract the second and third frame pieces 6b, In a state where 6c is developed laterally from the hinge 19 and the upper side of the frame body 6 is opened, the band transport device 1 is moved away from the shaping drum 3 as shown in FIG. As a result, the innermost end P 6 of the frame body 6 is positioned radially outward from the outermost diameter position B out of the bead B on the set band CB. And the bead B on the band CB do not interfere with each other. When the second and third frame pieces 6b and 6c are rotated around the hinge 19, the piston rod 34a of the cylinder 34 as the switching means is retracted in advance so that the divided arms 27a and 27b can freely rotate. It needs to be able to move.
一方、ビードセッター4をシェーピングドラム3から退去させる際には、図6(a)に仮想線で示すように、シリンダ43、47のピストンロッド43a、47aを引っ込めてビード保持部材40の第一、第二および第三の弧状体40a、40b、40cを外側に展開させた状態にて、図1(e)に示すように、ビードセッター1をシェーピングドラム3から退去させる。これにより、第一、第二および第三の弧状体40a、40b、40cの最内端P40a、P40b、P40cはセットしたバンドCB上のビードBの最外径位置Boutよりも径方向外側に位置するため、ビードセッター4の退去時にビード保持部材40とバンドCB上のビードBとが干渉することはない。
On the other hand, when the bead setter 4 is withdrawn from the shaping drum 3, the piston rods 43a and 47a of the cylinders 43 and 47 are retracted as shown by phantom lines in FIG. With the second and third arcuate bodies 40a, 40b, 40c deployed outward, the bead setter 1 is moved away from the shaping drum 3, as shown in FIG. As a result, the innermost ends P 40a , P 40b , P 40c of the first, second and third arcuate bodies 40a, 40b, 40c have a diameter larger than the outermost diameter position B out of the bead B on the set band CB. Since it is located on the outer side in the direction, the bead holding member 40 and the bead B on the band CB do not interfere when the bead setter 4 is moved away.
したがってかかる実施形態のバンド搬送装置1によれば、枠体6の周方向に略均等に配置された保持具9によってバンドCBを保持でき、バンドCBの保持時および解放時にバンドCBが歪んだり軸心がずれたりせず、バンドCBのセット精度を良好に保つことができる。また、枠体6を二以上の枠片6a、6b、6cに分割し、側方へ開放しつつ搬送基台5側に向けて移動可能に構成したので、バンド搬送装置1の退去時における側方へのはみ出し量を大幅に低減できて省スペース化を実現できる。しかも、保持具9の後退動作に加えて枠体6の開放によってバンドCBとの干渉を避けるようにしたので、保持具9の後退代を小さくでき、この点も省スペース化に有利に寄与するとともに枠体6を小さく形成し得るため小型化および軽量化を図ることができる。
Therefore, according to the band conveyance device 1 of this embodiment, the band CB can be held by the holders 9 that are arranged substantially evenly in the circumferential direction of the frame body 6, and the band CB is distorted or axially held when the band CB is held and released. The set accuracy of the band CB can be kept good without being misaligned. In addition, since the frame body 6 is divided into two or more frame pieces 6a, 6b, 6c and is configured to be movable toward the transport base 5 side while being opened to the side, the side when the band transport device 1 is moved out The amount of protrusion to the direction can be greatly reduced, and space saving can be realized. Moreover, since the interference with the band CB is avoided by opening the frame body 6 in addition to the retreating operation of the holder 9, the retreat margin of the holder 9 can be reduced, which also contributes to space saving. In addition, since the frame body 6 can be formed small, the size and weight can be reduced.
また、このバンド搬送装置1によれば、枠体6を、周方向に分割された三つの枠片6a、6b、6cにより構成したことから、枠体6を二分割構造とする場合と比べて、シェーピングドラム3からの退去時における枠体6の側方へのはみ出し量をより低減することができる。
Moreover, according to this band conveying apparatus 1, since the frame 6 was comprised by the three frame pieces 6a, 6b, 6c divided | segmented in the circumferential direction, compared with the case where the frame 6 is made into 2 division structure. Further, the amount of protrusion of the frame body 6 to the side at the time of withdrawal from the shaping drum 3 can be further reduced.
さらに、このバンド搬送装置1によれば、ヒンジ19の両側に位置するベルクランク26をつなぐリンクアーム27を二つの分割アーム27a、27bで構成するとともに、これらの分割アーム27a、27b同士の相対回動する択一的に許可および停止する切替え手段としてのシリンダ34を設けたことから、簡素な構造によって、リンク機構11を介した保持具9の径方向に沿った進退移動と、ヒンジ19を基点とした第二および第三の枠片6b、6cの回動とを確実に実現することができる。
Furthermore, according to this band transport apparatus 1, the link arm 27 that connects the bell cranks 26 located on both sides of the hinge 19 is constituted by the two divided arms 27a and 27b, and the relative rotation between the divided arms 27a and 27b is established. Since the cylinder 34 is provided as a switching means for selectively permitting and stopping to move, a simple structure advances and retracts along the radial direction of the holder 9 via the link mechanism 11 and the hinge 19 serves as a base point. The second and third frame pieces 6b and 6c can be reliably rotated.
さらに、このバンド搬送装置1によれば、保持具9を最終後退位置にてロックするロック手段としてのシリンダ36を備えていることから、第二および第三の枠片6b、6cをヒンジ19を基点に外側に開いた際に、保持具9が重力により不意に径方向内側に降下してくることがなく、シェーピングドラム3上のバンドCBとの接触をより一層確実に回避することができる。
Further, according to this band transport device 1, since the cylinder 36 is provided as a locking means for locking the holder 9 in the final retracted position, the second and third frame pieces 6b, 6c are connected to the hinge 19. When the holder 9 is opened outward from the base point, the holder 9 does not unexpectedly descend radially inward due to gravity, and the contact with the band CB on the shaping drum 3 can be more reliably avoided.
しかも、このバンド搬送装置1によれば、保持具9によってバンドCBを内周面側から保持することとしたことから、保持具9でバンドCBを保持した際のバンドCBの変形や芯ずれをより確実に防止することができる。
Moreover, according to the band transport device 1, since the band CB is held from the inner peripheral surface side by the holder 9, the band CB is deformed or misaligned when the band CB is held by the holder 9. It can prevent more reliably.
以上、図示例に基づき説明したが、この発明は上述の例に限定されるものではない。例えば、保持具は、各枠片に同数設けることが好ましいので、枠体が三つの枠片からなる場合には、製造する生タイヤの大きさに応じて、保持具を三つないし九つとしてもよい。また、枠体移動手段による枠体の上下移動と開閉手段による枠体の開閉とは、上述した例では別個に行うと説明したが、これらの動作を、例えばシリンダおよびリンクを用いて同時に行うこととしてもよい(図7参照)。
As mentioned above, although demonstrated based on the example of illustration, this invention is not limited to the above-mentioned example. For example, since it is preferable to provide the same number of holders in each frame piece, when the frame body is composed of three frame pieces, the number of holders is set to three or nine depending on the size of the raw tire to be manufactured. Also good. Further, it has been described that the vertical movement of the frame body by the frame body moving means and the opening and closing of the frame body by the opening / closing means are performed separately in the above-described example, but these operations are performed simultaneously using, for example, a cylinder and a link. (See FIG. 7).
かくしてこの発明により、シェーピングドラムへのバンドのセット精度を良好に保ちつつも省スペース化を実現でき、しかも小型かつ軽量なバンド搬送装置を提供することが可能となった。
Thus, according to the present invention, it is possible to provide a small and lightweight band transport device that can achieve space saving while maintaining a good accuracy of setting the band on the shaping drum.
