Description

フィッティング装置Fitting device
　本発明は、ホイールに嵌められているタイヤを、上ハンマーと下ハンマーで打つことにより、前記タイヤのビード部を前記ホイールのリムフランジ部に密着させるフィッティング装置に関する。 The present invention relates to a fitting device in which a bead portion of the tire is brought into close contact with a rim flange portion of the wheel by hitting a tire fitted to the wheel with an upper hammer and a lower hammer.
　ホイールにタイヤを組付けると、ホイールのリムフランジ部とタイヤのビード部との間に空気が封じ込まれることがある。この空気は車両の走行性能に悪影響を及ぼすために、除去することが望まれる。
　そこで、タイヤのサイドウオール部のビード部寄りの部位を、ハンマーで叩いて空気を押し出しつつタイヤのビード部をホイール側のリムフランジ部に密着させるフィッティング工程が実施される。このフィッティング工程を実行するフィッティング装置が知られている（例えば、特許文献１参照）。 When a tire is assembled to a wheel, air may be trapped between the rim flange portion of the wheel and the bead portion of the tire. Since this air adversely affects the running performance of the vehicle, it is desirable to remove it.
Therefore, a fitting step is performed in which the bead portion of the tire is brought into close contact with the rim flange portion on the wheel side while pushing a portion near the bead portion of the sidewall portion of the tire with a hammer to push out air. A fitting device that performs this fitting step is known (see, for example, Patent Document 1).
　特許文献１に開示されているフィッティング装置は、タイヤのサイドウオール部のビード部寄りの部位を、押圧ローラで連続して打撃する。アームの一端に押圧ローラが設けられ、アームの他端に、卵形カム及びバネが設けられている。卵形カムを１回転させることで、１回の打撃が行われる。 The fitting device disclosed in Patent Document 1 continuously hits a portion near a bead portion of a side wall portion of a tire with a pressing roller. A pressing roller is provided at one end of the arm, and an egg-shaped cam and a spring are provided at the other end of the arm. One hit is performed by rotating the egg-shaped cam once.
　卵形カムを１回転させることで、バネは圧縮と伸びを繰り返す。バネは長期間使用すると、劣化して復元性能が低下し、所望の付勢作用が発揮されなくなる。そのため、バネは定期的に交換する必要がある。交換費用が嵩む。
　また、フィッティング装置を止めてバネの交換が行われる。止めるため、生産性が低下する。
　すなわち、特許文献１に開示されているフィッティング装置には、交換費用と生産性低下との２つの問題がある。 By rotating the egg-shaped cam once, the spring repeats compression and extension. If the spring is used for a long period of time, it deteriorates and the restoring performance is lowered, and the desired biasing action is not exhibited. Therefore, it is necessary to replace the spring periodically. Replacement costs increase.
Further, the spring is exchanged by stopping the fitting device. Because it stops, productivity decreases.
That is, the fitting device disclosed in Patent Document 1 has two problems, that is, replacement cost and productivity reduction.
　また、卵形カムは一打撃につき１回転させるために、卵形カムを高速で回転させる。駆動源としてのカム駆動モータは高価で大型なものとなる。
　タイヤ組立体のためのフィッティング装置において、バネを省くことができると共にカム駆動モータ（駆動機構）の低コスト化及小型化が望まれる。 In addition, the egg-shaped cam is rotated at a high speed in order to rotate the egg-shaped cam once per hit. A cam drive motor as a drive source is expensive and large.
In a fitting device for a tire assembly, a spring can be omitted and a reduction in cost and size of a cam drive motor (drive mechanism) is desired.

　本発明は、バネを省くことができると共にカムを駆動する駆動機構の低コスト化及小型化が図れるタイヤ組立体のためのフィッティング装置を提供することを課題とする。 An object of the present invention is to provide a fitting device for a tire assembly that can omit a spring and can reduce the cost and size of a drive mechanism that drives a cam.

A gripping mechanism for gripping an axle insertion hole provided in the wheel;
A rotating mechanism that rotates the gripping mechanism around the axis of the axle insertion hole;
A first rail disposed at a different location from the rotation mechanism and extending toward the rotation mechanism;
A sliding plate placed on the first rail;
A first drive mechanism for moving the sliding plate along the first rail;
A column that stands on this sliding plate;
A second rail attached to the column so as to extend vertically,
An upper elevating plate and a lower elevating plate mounted on the second rail;
A second drive mechanism that is attached to the support column and moves so that the upper elevating plate and the lower elevating plate approach or separate from each other;
An upper support plate attached to the upper lift plate and having an upper support shaft;
An upper cam plate having a triangular cam groove on a side surface and rotatably attached to the upper support shaft;
A third drive mechanism that is attached to the upper lift plate and rotates the upper cam plate;
An upper crank arm that is swingably supported by the upper support plate and includes an upper roller that fits into the cam groove at one end and the upper hammer at the other end;
A lower support plate attached to the lower lifting plate and having a lower support shaft;
A lower cam plate having a triangular cam groove on a side surface and rotatably attached to the lower support shaft;
A fourth drive mechanism attached to the lower lift plate and rotating the lower cam plate;
The lower support plate includes a lower roller that is swingably supported by the lower support plate and fits in the lower cam groove at one end, and a lower crank arm that includes the lower hammer at the other end.
　請求項１に係る発明では、上クランクアームの一端に上ローラを備え、上クランクアームの他端に上ハンマーを備え、上ローラをカム溝に嵌める。上ローラがカム溝に嵌っているため、バネは不要となる。下ローラについても同様に、バネは不要となる。 In the invention according to claim 1, an upper roller is provided at one end of the upper crank arm, an upper hammer is provided at the other end of the upper crank arm, and the upper roller is fitted into the cam groove. Since the upper roller is fitted in the cam groove, no spring is required. Similarly, no spring is required for the lower roller.
　また、カム溝は三角形状を呈する。三角形の各辺の中央が小径部となり、三角形の各頂点が大径部となる。すなわち、上カムプレート１回転当たり、上ハンマーを３回上下させることができる。第３駆動機構の回転速度を、従来の速度の１／３にすることができる。回転速度が１／３であるため、第３駆動機構の低コスト化及び小型化が容易に達成できる。
　同様に、下カムプレート１回転当たり、下ハンマーを３回上下させることができため、第４駆動機構の低コスト化及び小型化が容易に達成できる。 Further, the cam groove has a triangular shape. The center of each side of the triangle is a small diameter portion, and each vertex of the triangle is a large diameter portion. That is, the upper hammer can be moved up and down three times per one rotation of the upper cam plate. The rotational speed of the third drive mechanism can be reduced to 1/3 of the conventional speed. Since the rotational speed is 1/3, the cost and size of the third drive mechanism can be easily reduced.
Similarly, since the lower hammer can be moved up and down three times per rotation of the lower cam plate, the cost and size of the fourth drive mechanism can be easily reduced.

　タイヤ１１にホイール１２を単に嵌めたのでは、ビード部１６とリムフランジ部１４の間に不可避的に隙間が発生し、空気が溜まる。この空気は乗り心地性能に影響するため、本発明のフィッティング装置３０を用いてビード部１６とリムフランジ部１４を密着させ、空気を除去することが求められる。 If the wheel 12 is simply fitted to the tire 11, a gap is inevitably generated between the bead portion 16 and the rim flange portion 14, and air accumulates. Since this air affects the riding comfort performance, it is required to remove the air by bringing the bead portion 16 and the rim flange portion 14 into close contact with each other using the fitting device 30 of the present invention.
　以下、本発明のフィッティング装置３０の詳細を説明する。
　図２に示すように、タイヤ組立体１０を水平搬送する入口側搬送テーブル２１と、タイヤ組立体１０を水平搬送する出口側搬送テーブル２２との間に、フィッティング装置３０が配置される。入口側搬送テーブル２１及び出口側搬送テーブル２２は、テーブルフレーム２３とこのテーブルフレーム２３に所定ピッチで取付けられた複数のローラ２４とからなる。 Hereinafter, details of the fitting device 30 of the present invention will be described.
As shown in FIG. 2, a fitting device 30 is disposed between an entrance-side transport table 21 that horizontally transports the tire assembly 10 and an exit-side transport table 22 that horizontally transports the tire assembly 10. The entrance-side transport table 21 and the exit-side transport table 22 include a table frame 23 and a plurality of rollers 24 attached to the table frame 23 at a predetermined pitch.
　フィッティング装置３０は、入口側搬送テーブル２１と出口側搬送テーブル２２との間に配置される一対の中間テーブル３１、３２と、これらの一対の中間テーブル３１、３２の間に配置される把持機構７０と、一方の中間テーブル３２の搬送ラインに直交する方向に延びている第１レール３３、３３と、後述する図３で説明するその他の機構を備えている。 The fitting device 30 includes a pair of intermediate tables 31 and 32 disposed between the inlet-side transport table 21 and the outlet-side transport table 22 and a gripping mechanism 70 disposed between the pair of intermediate tables 31 and 32. And first rails 33, 33 extending in a direction perpendicular to the conveyance line of one intermediate table 32, and other mechanisms described later with reference to FIG.
　なお、一対の中間テーブル３１、３２は共通のテーブルフレームに取付けられており、一緒に昇降する。 Note that the pair of intermediate tables 31 and 32 are attached to a common table frame and move up and down together.
　入口側搬送テーブル２１と出口側搬送テーブル２２に、各々ローラ２４が設けられている。ローラ２４は、従動歯車２５を介して無端チェーン２６により回される。ローラ２４によりタイヤ組立体１０が水平搬送される。
　そして、入口側搬送テーブル２１の先端には、ストッパロッド２７とシリンダユニット２８が設けられている。シリンダユニット２８が伸動すると、ストッパロッド２７が上がり、タイヤ組立体１０の前進を阻止する。シリンダユニット２８が縮動すると、ストッパロッド２７が下がり、タイヤ組立体１０の前進が許容される。 A roller 24 is provided on each of the entrance-side transport table 21 and the exit-side transport table 22. The roller 24 is rotated by an endless chain 26 via a driven gear 25. The tire assembly 10 is horizontally conveyed by the rollers 24.
A stopper rod 27 and a cylinder unit 28 are provided at the front end of the entrance-side transport table 21. When the cylinder unit 28 is extended, the stopper rod 27 is raised to prevent the tire assembly 10 from moving forward. When the cylinder unit 28 is contracted, the stopper rod 27 is lowered, and the tire assembly 10 is allowed to advance.
　中間テーブル３１、３２に前のタイヤ組立体１０が載っている。ストッパロッド２７と一緒にストッパロッド５１が下げられる。
　入口側搬送テーブル２１に載っている後のタイヤ組立体１０を前進させる。後のタイヤ組立体１０が、前のタイヤ組立体１０を出口側搬送テーブル２２へ押し出す。 The front tire assembly 10 is placed on the intermediate tables 31 and 32. The stopper rod 51 is lowered together with the stopper rod 27.
The tire assembly 10 on the entrance side transfer table 21 is advanced. The rear tire assembly 10 pushes the front tire assembly 10 to the outlet-side transfer table 22.
　後のタイヤ組立体１０がストッパロッド５１で位置決めされながら、中間テーブル３１、３２に載る。後のタイヤ組立体１０にフィッティング処理が施される。
　前のタイヤ組立体１０は、出口側搬送テーブル２２のローラ２４により搬出される。 The rear tire assembly 10 is placed on the intermediate tables 31 and 32 while being positioned by the stopper rod 51. A fitting process is performed on the subsequent tire assembly 10.
The front tire assembly 10 is carried out by the rollers 24 of the outlet side conveyance table 22.
　図３に示すように、第１レール３３に第１ガイド部３４、３４を介して摺動板３５が載せられる。この摺動板３５の下部に第１ナット３６が設けられ、この第１ナット３６にねじ込まれる第１ねじ軸３７が第１レール３３に平行に敷設される。第１ねじ軸３７は第１駆動機構３８で回される。第１ナット３６が第１ねじ軸３７で送られるため、摺動板３５が図面左右方向へ移動する。 As shown in FIG. 3, the sliding plate 35 is placed on the first rail 33 via the first guide portions 34, 34. A first nut 36 is provided at a lower portion of the sliding plate 35, and a first screw shaft 37 screwed into the first nut 36 is laid in parallel to the first rail 33. The first screw shaft 37 is rotated by the first drive mechanism 38. Since the first nut 36 is fed by the first screw shaft 37, the sliding plate 35 moves in the horizontal direction of the drawing.
　第１駆動機構３８は、減速機付き電動機が好適である。後述する第２以降の駆動機構も同様。
　また、第１ねじ軸３７はボールねじが好適であり、この場合は第１ナット３６はボールナットを適用する。ボールねじは、摩擦抵抗がごく小さいため、第１駆動機構３８の負担を軽減する利点がある。後述する第２以降のねじ軸も同様。 The first drive mechanism 38 is preferably an electric motor with a speed reducer. The same applies to the second and subsequent drive mechanisms described later.
The first screw shaft 37 is preferably a ball screw. In this case, the first nut 36 is a ball nut. The ball screw has an advantage of reducing the burden on the first drive mechanism 38 because the frictional resistance is extremely small. The same applies to the second and subsequent screw shafts described later.
　そして、摺動板３５から板状の支柱３９が上へ延びている。この支柱３９に縦向きに第２レール４１、４１が設けられる。そして、第２レール４１に第２ガイド部４２、４２を介して横長の上昇降板４３及び下昇降板４４が移動可能に取付けられる。
　上昇降板４３及び下昇降板４４の図面奥に第２ナット４５、４５が設けられ、これの第２ナット４５、４５にねじ込まれる第２ねじ軸４６が第２レール４１に平行に敷設される。 A plate-like column 39 extends upward from the sliding plate 35. Second rails 41 and 41 are provided on the support column 39 in the vertical direction. A horizontally long upper elevating plate 43 and a lower elevating plate 44 are movably attached to the second rail 41 via the second guide portions 42, 42.
Second nuts 45, 45 are provided behind the upper lifting plate 43 and the lower lifting plate 44, and a second screw shaft 46 screwed into the second nuts 45, 45 is laid in parallel to the second rail 41.
　なお、第２ねじ軸４６は、中間部より一方に右ねじが刻まれ、他方に左ねじが刻まれた両ねじ軸部材である。
　第２ねじ軸４６は第２駆動機構４７で回される。第２ナット４５、４５が第２ねじ軸４６で送られるため、上昇降板４３及び下昇降板４４が互いに接近する又は離間するように移動する。 The second screw shaft 46 is a double screw shaft member in which a right screw is engraved on one side and a left screw is engraved on the other side from the intermediate portion.
The second screw shaft 46 is rotated by the second drive mechanism 47. Since the second nuts 45 and 45 are fed by the second screw shaft 46, the upper elevating plate 43 and the lower elevating plate 44 move so as to approach or separate from each other.
　また、中間テーブル３１、３２は、昇降シリンダ４８のピストンロッド４９で支持され、実線で示す上位位置と想像線で示す下位位置の何れかの位置とされる。上位位置は入口側搬送テーブル（図１、符号２１）に対応する高さ位置である。下位位置は、把持機構７０よりも下の高さに設定される。 Further, the intermediate tables 31 and 32 are supported by the piston rod 49 of the elevating cylinder 48 and are set to either the upper position indicated by the solid line or the lower position indicated by the imaginary line. The upper position is a height position corresponding to the entrance-side transport table (FIG. 1, reference numeral 21). The lower position is set to a height below the gripping mechanism 70.
　図４に示すように、中間テーブル３１は、複数のテーブルローラ３１ａと、これらのテーブルローラ３１ａを回転自在に支持するテーブルフレーム３１ｂと、昇降シリンダ４８、４８とからなるが、更に、出口側にストッパロッド５１及びこのストッパロッド５１を昇降させるシリンダユニット５２を備える。このストッパロッド５１は、シリンダユニット５２の伸動により一対のテーブルローラ３１ａ、３１ａ間から上へ突出し、タイヤ組立体１０の移動を阻止する。シリンダユニット５２を縮動すると一対のテーブルローラ３１ａ、３１ａ間にストッパロッド５１が埋没し、タイヤ組立体１０は移動可能となる。 As shown in FIG. 4, the intermediate table 31 includes a plurality of table rollers 31a, a table frame 31b that rotatably supports these table rollers 31a, and elevating cylinders 48 and 48. A stopper rod 51 and a cylinder unit 52 for raising and lowering the stopper rod 51 are provided. The stopper rod 51 protrudes upward from between the pair of table rollers 31 a and 31 a by the extension of the cylinder unit 52, and prevents the tire assembly 10 from moving. When the cylinder unit 52 is contracted, the stopper rod 51 is buried between the pair of table rollers 31a and 31a, and the tire assembly 10 is movable.
　図２に示すように、一対のストッパロッド５１、５１に想像線で示すように、タイヤ組立体１０が当たると、いわゆるＶブロック原理（Ｖ溝に丸棒を嵌めるとＶ溝の中心線上に丸棒の中心が位置決めされる。）により、タイヤ組立体１０が図２左右及び上下方向が位置決めされる。 As shown in FIG. 2, when the tire assembly 10 hits the pair of stopper rods 51, 51 as indicated by an imaginary line, the so-called V block principle (when a round bar is fitted in the V groove, 2), the tire assembly 10 is positioned in the left-right and up-down directions in FIG.
　図５に示すように、回転機構６０は、支持枠６１と、この支持枠６１の上部に軸受６２を介して回転自在に支持される回転軸６３と、この回転軸６３に設けられる従動スプロケット６４と、支持枠６１に設けられる減速機付きモータ６５と、このモータ６５の軸に設けられる駆動スプロケット６６と、この駆動スプロケット６６と従動スプロケット６４に巻回したチェーン６７とからなる。回転軸６３の上部に把持機構７０が取付けられる。すなわち、回転機構６０は、把持機構７０を支持しつつ回す装置である。 As shown in FIG. 5, the rotation mechanism 60 includes a support frame 61, a rotation shaft 63 that is rotatably supported on the upper portion of the support frame 61 via a bearing 62, and a driven sprocket 64 provided on the rotation shaft 63. And a motor 65 with a speed reducer provided on the support frame 61, a drive sprocket 66 provided on the shaft of the motor 65, and a chain 67 wound around the drive sprocket 66 and the driven sprocket 64. A gripping mechanism 70 is attached to the upper part of the rotating shaft 63. That is, the rotation mechanism 60 is a device that rotates while supporting the gripping mechanism 70.
　図６に示すように、把持機構７０は、回転軸６３に固定されるシリンダ７１と、このシリンダ７１に上下移動可能に収納されるピストン７２と、このピストン７２から上に延びると共に上のエンドプレート７３を貫通して上方へ突出し上端がテーパ面７４であるピストンロッド７５と、エンドプレート７３にスライド移動可能に取付けら得る爪部７６、７６と、これらの爪部７６、７６を回転中心側へ付勢するスプリング７７、７７と、爪部７６、７６を上から抑えるカバー部材７８とからなる。カバー部材７８は、エンドプレート７３にねじ又はボルトなどにより固定される。 As shown in FIG. 6, the gripping mechanism 70 includes a cylinder 71 fixed to the rotating shaft 63, a piston 72 accommodated in the cylinder 71 so as to be movable up and down, and an upper end plate extending upward from the piston 72. 73, a piston rod 75 having a tapered surface 74 protruding upward, claw portions 76, 76 that can be slidably attached to the end plate 73, and these claw portions 76, 76 toward the center of rotation. It consists of springs 77 and 77 to be biased and a cover member 78 that holds the claw portions 76 and 76 from above. The cover member 78 is fixed to the end plate 73 with screws or bolts.
　図７に示すように、爪部７６は、全周３６０°の厚肉を複数（この例では、約１２０°の円弧体、３個）に分割したものであり、径外方へ延びるテール部７９を備える。このテール部７９は、ピストンロッド７５の中心から放射状に延びるようにエンドプレート７３に刻設された放射溝８１に嵌められる。結果、爪部７６はピストンロッド７５の中心に向かって前進する。 As shown in FIG. 7, the claw portion 76 is obtained by dividing a thick wall having a total circumference of 360 ° into a plurality of pieces (in this example, about 120 ° arcuate bodies, three pieces), and a tail portion extending radially outward. 79. The tail portion 79 is fitted into a radial groove 81 formed in the end plate 73 so as to extend radially from the center of the piston rod 75. As a result, the claw 76 advances toward the center of the piston rod 75.
　図６において、ピストン７２を油圧又は空圧で上昇させると、テーパ面７４の作用で、左右の爪部７６、７６が径外方へ移動する。結果、爪部７６、７６の外径が増大する。ピストン７２を下げると、スプリング７７、７７の付勢作用で爪部７６、７６の外径が減少する。 6, when the piston 72 is raised by hydraulic pressure or pneumatic pressure, the left and right claw portions 76 and 76 are moved radially outward by the action of the tapered surface 74. As a result, the outer diameters of the claw portions 76 and 76 are increased. When the piston 72 is lowered, the outer diameters of the claw portions 76 and 76 are reduced by the biasing action of the springs 77 and 77.
　図３にて、タイヤ組立体１０が下げられると、爪部７６、７６が車軸挿通孔１３に挿通する。カバー７８の上面にホイール１２が当たると、タイヤ組立体１０は下降を停止する。中間テーブル３１、３２は更に下がる。すると、タイヤ組立体１０はカバー７８に載った状態となる。次に、爪部７６、７６を左右に開くと、爪部７６、７６でホイール１２が把持（チャック）される。並行して、爪部７６、７６が同期して開くため、タイヤ組立体１０の中心（車軸挿通孔の軸心）が、把持機構７０の回転中心に合致するように、センターリングがなされる。 3, when the tire assembly 10 is lowered, the claw portions 76 and 76 are inserted into the axle insertion hole 13. When the wheel 12 hits the upper surface of the cover 78, the tire assembly 10 stops descending. The intermediate tables 31 and 32 are further lowered. Then, the tire assembly 10 is placed on the cover 78. Next, when the claw portions 76 and 76 are opened to the left and right, the wheel 12 is gripped (chucked) by the claw portions 76 and 76. In parallel, since the claw portions 76 open in synchronization, the centering is performed so that the center of the tire assembly 10 (the axis of the axle insertion hole) matches the rotation center of the gripping mechanism 70.
　図８に示すように、上ハンマー機構９０は、上昇降板４３に取付けられる変速機９１と、この変速機９１に固定される上支持プレート９２と、この上支持プレート９２から所定距離を保って平行に配置される別の上支持プレート９３と、これらの上支持プレート９２、９３同士を連結する連結ボルト９４と、上支持プレート９２、９３の一端に渡した揺動用軸９５に揺動可能に支持される上クランクアーム９６と、上支持プレート９２、９３に渡した上支軸９７と、変速機９１に付設され上支軸９７を回す第３駆動機構９８と、上支軸９７に一体的に取付けられる上カムプレート９９を備えている。 As shown in FIG. 8, the upper hammer mechanism 90 is parallel to the transmission 91 attached to the upper elevating plate 43, the upper support plate 92 fixed to the transmission 91, and a predetermined distance from the upper support plate 92. The upper support plate 93 disposed on the upper support plate 92, the connection bolt 94 connecting the upper support plates 92, 93, and the swinging shaft 95 across one end of the upper support plates 92, 93 are swingably supported. The upper crank arm 96, the upper support shaft 97 passed to the upper support plates 92, 93, the third drive mechanism 98 attached to the transmission 91 and turning the upper support shaft 97, and the upper support shaft 97. An upper cam plate 99 to be attached is provided.
　図９に示すように、第３駆動機構９８で回される上カムプレート９９には、側面に三角形のカム溝１０１が備えられる。上クランクアーム９６の一端に備える上ローラ１０２がカム溝１０１に嵌められる。上クランクアーム９６の他端に上ハンマー１０３が取付けられている。 As shown in FIG. 9, the upper cam plate 99 rotated by the third drive mechanism 98 is provided with a triangular cam groove 101 on the side surface. An upper roller 102 provided at one end of the upper crank arm 96 is fitted in the cam groove 101. An upper hammer 103 is attached to the other end of the upper crank arm 96.
　図１０に基づいて、上カムプレート９９の作用を説明する。
　図１０（ａ）に示すように、カム溝１０１において、三角形の辺の中間に、回転半径がｒ１である小径部１０４ができる。この小径部１０４に上ローラ１０２が存在すると、上クランクアーム９６が揺動用軸９５を中心に図時計方向に揺動し、上ハンマー１０３は上昇する。 The operation of the upper cam plate 99 will be described based on FIG.
As shown in FIG. 10A, in the cam groove 101, a small-diameter portion 104 having a rotation radius r1 is formed in the middle of the triangular side. When the upper roller 102 exists in the small diameter portion 104, the upper crank arm 96 swings in the clockwise direction around the swing shaft 95, and the upper hammer 103 rises.
　次に、図１０（ｂ）に示すように、三角形の頂点に、回転半径Ｒ１である大径部１０５ができる。この大径部１０５に上ローラ１０２が差し掛かると、上クランクアーム９６は揺動用軸９５を中心に図反時計方向に揺動し、上ハンマー１０３はタイヤ１１のサイドウオール部１５を打つ（叩く）。 Next, as shown in FIG. 10B, a large-diameter portion 105 having a rotation radius R1 is formed at the apex of the triangle. When the upper roller 102 reaches the large-diameter portion 105, the upper crank arm 96 swings counterclockwise around the swing shaft 95, and the upper hammer 103 strikes (beats) the side wall portion 15 of the tire 11. ).
　上カムプレート９９を１回転させると、上ハンマー１０３は３回上下する。
　図９に示す第３駆動機構９８の回転速度を、従来の速度の１／３にすることができる。電動モータの出力（ｋｗ）は、係数×トルク×回転速度で算出される。トルクが同一であって回転速度が１／３であれば、要求出力も１／３になる。電動モータの大きさ及び価格は要求出力により定まるため、出力が１／３になると電動モータのサイズが小さくなり、安価となる。すなわち、第３駆動機構９８の低コスト化及び小型化が容易に達成できる。 When the upper cam plate 99 is rotated once, the upper hammer 103 moves up and down three times.
The rotational speed of the third drive mechanism 98 shown in FIG. 9 can be reduced to 1/3 of the conventional speed. The output (kw) of the electric motor is calculated by coefficient × torque × rotational speed. If the torque is the same and the rotation speed is 1/3, the required output is also 1/3. Since the size and price of the electric motor are determined by the required output, when the output is reduced to 1/3, the size of the electric motor is reduced and the cost is reduced. That is, the cost and size of the third drive mechanism 98 can be easily achieved.
　図１１に示すように、下ハンマー機構１１０は、下昇降板４４に取付けられる変速機１１１と、この変速機１１１に固定される下支持プレート１１２と、この下支持プレート１１２から所定距離を保って平行に配置される別の下支持プレート１１３と、これらの下支持プレート１１２、１１３同士を連結する連結ボルト１１４と、下支持プレート１１２、１１３の一端に渡した揺動用軸１１５に揺動可能に支持される下クランクアーム１１６と、下支持プレート１１２、１１３に渡した下支軸１１７と、変速機９１に付設され下支軸１１７を回す第４駆動機構１１８と、下支軸１１７に一体的に取付けられる下カムプレート１１９を備えている。 As shown in FIG. 11, the lower hammer mechanism 110 includes a transmission 111 attached to the lower lift plate 44, a lower support plate 112 fixed to the transmission 111, and a predetermined distance from the lower support plate 112. Another lower support plate 113 arranged in parallel, a connecting bolt 114 that connects these lower support plates 112 and 113, and a swing shaft 115 that extends across one end of the lower support plates 112 and 113 can swing. The lower crank arm 116 that is supported, the lower support shaft 117 that passes over the lower support plates 112 and 113, the fourth drive mechanism 118 that is attached to the transmission 91 and rotates the lower support shaft 117, and the lower support shaft 117. And a lower cam plate 119 attached to the head.
　図１２に示すように、第４駆動機構１１８で回される下カムプレート１１９には、側面に三角形のカム溝１２１が備えられる。下クランクアーム１１６の一端に備える下ローラ１２２がカム溝１２１に嵌められる。下クランクアーム１１６の他端に下ハンマー１２３が取付けられている。
　第４駆動機構１１８を駆動源として駆動される下ハンマー１２３の作動の説明は省略する。 As shown in FIG. 12, the lower cam plate 119 rotated by the fourth drive mechanism 118 is provided with a triangular cam groove 121 on the side surface. A lower roller 122 provided at one end of the lower crank arm 116 is fitted in the cam groove 121. A lower hammer 123 is attached to the other end of the lower crank arm 116.
The description of the operation of the lower hammer 123 driven by using the fourth drive mechanism 118 as a drive source is omitted.
　次に、本発明に係るタイヤ組立体のフィッティング装置３０の総合的な作用を説明する。
　図２にて、ストッパロッド５１を上げておき、入口側搬送テーブル２１上のタイヤ組立体１０を中間テーブル３１、３２へ移す。すると、タイヤ組立体１０は所定位置で停止する。 Next, the overall operation of the tire assembly fitting device 30 according to the present invention will be described.
In FIG. 2, the stopper rod 51 is raised, and the tire assembly 10 on the entrance-side transport table 21 is moved to the intermediate tables 31 and 32. Then, the tire assembly 10 stops at a predetermined position.
　次に、図３にて、中間テーブル３１、３２を下げる。下降の途中で、タイヤ組立体１０は把持機構７０に載る。中間テーブル３１、３２は更に下がるため、タイヤ組立体１０は把持機構７０にだけ載る。 Next, in FIG. 3, the intermediate tables 31 and 32 are lowered. In the middle of descending, the tire assembly 10 is placed on the gripping mechanism 70. Since the intermediate tables 31 and 32 are further lowered, the tire assembly 10 is placed only on the gripping mechanism 70.
　次に、図６にてピストンロッド７５を上昇させると、爪部７６、７６が左右に広がり、図３にてタイヤ組立体１０の車軸挿通孔１３に爪部７６、７６が噛み合う。以上により爪部７６、７６でタイヤ組立体１０が強固にチャッキングされる。 Next, when the piston rod 75 is raised in FIG. 6, the claw portions 76, 76 spread left and right, and the claw portions 76, 76 mesh with the axle insertion hole 13 of the tire assembly 10 in FIG. 3. Thus, the tire assembly 10 is firmly chucked by the claw portions 76 and 76.
　次に、第１駆動機構３８により支柱３９が所定距離前進（図左へ移動）する。結果、上ハンマー１０３がタイヤ１１に臨む。第２駆動機構４７、４７により上下の昇降板４３、４４を互いに接近させる。 Next, the support 39 is moved forward (moved to the left in the figure) by the first drive mechanism 38. As a result, the upper hammer 103 faces the tire 11. The upper and lower elevating plates 43 and 44 are moved closer to each other by the second drive mechanisms 47 and 47.
　次に、図５に示す減速機付きモータ６５により、把持機構７０を回すことで、タイヤ組立体を回す。
　この状態で、上クランクアーム９６と下クランクアーム１１６を揺動させて上ハンマー１０３と下ハンマー１２３を上下させ、所望のフィッティングを実施する。このフィッティングにより、タイヤ１１のサイドウオール部１５のビード部寄りの部位を、連続して打撃する。結果、空気を除去することができ、図１に示すビード部１６をリムフランジ部１４に密着させることができる。 Next, the tire assembly is rotated by rotating the gripping mechanism 70 by the motor 65 with a speed reducer shown in FIG.
In this state, the upper crank arm 96 and the lower crank arm 116 are swung and the upper hammer 103 and the lower hammer 123 are moved up and down to perform a desired fitting. By this fitting, a portion near the bead portion of the sidewall portion 15 of the tire 11 is continuously hit. As a result, air can be removed, and the bead portion 16 shown in FIG.
　尚、第１～第４駆動機構は、電動モータの他、空圧モータや油圧モータであってもよい。 The first to fourth drive mechanisms may be pneumatic motors or hydraulic motors in addition to electric motors.
