One set of upper and lower divided rims 6 is placed on each placement unit 10.
この発明の一実施形態に係るリム交換補助装置11は、タイヤ試験機1とリムストッカー7との間に配置されている。リム交換補助装置11とリムストッカー7とは、リム交換システム50を構成する。リム交換補助装置11は、床面に固定されたベース部12と、ベース部12によって水平方向へスライド可能に支持されたシャトル部13とを含む。シャトル部13は、ベース部12のレール部12Aに連結された横移動部14と、横移動部14の支柱部14Aによって支持された縦移動部15と、縦移動部15に設けられた長方形板状の回転部16と、回転部16に設けられた複数のセット部17とを含む。 A rim replacement auxiliary device 11 according to an embodiment of the present invention is disposed between the tire testing machine 1 and the rim stocker 7. The rim replacement assisting device 11 and the rim stocker 7 constitute a rim replacement system 50. The rim replacement assisting device 11 includes a base portion 12 fixed to the floor surface and a shuttle portion 13 supported by the base portion 12 so as to be slidable in the horizontal direction. The shuttle unit 13 includes a lateral movement unit 14 connected to the rail unit 12 </ b> A of the base unit 12, a longitudinal movement unit 15 supported by a support column 14 </ b> A of the lateral movement unit 14, and a rectangular plate provided in the longitudinal movement unit 15. And a plurality of set parts 17 provided on the rotating part 16.
横移動部14は、モータ等の駆動部(図示せず)によって、タイヤ試験機1とリムストッカー7との間で横移動する。縦移動部15は、別の駆動部(図示せず)によって、縦移動する。回転部16は、さらに別の駆動部(図示せず)によって、回転部16の長手方向中央を通る縦軸Jまわりに回転する。セット部17は、馬蹄状に形成され、例えば2つ存在し、回転部16において縦軸Jを挟んだ両端部に1つずつ配置されている。 The lateral movement unit 14 is laterally moved between the tire testing machine 1 and the rim stocker 7 by a drive unit (not shown) such as a motor. The vertical movement unit 15 is moved vertically by another drive unit (not shown). The rotating unit 16 is rotated around the longitudinal axis J passing through the center in the longitudinal direction of the rotating unit 16 by another drive unit (not shown). The set part 17 is formed in a horseshoe shape, for example, there are two, and one set is disposed at each end of the rotating part 16 with the vertical axis J interposed therebetween.
以下では、タイヤ試験機1の回転軸2に取り付けられた上下分割リム6Aを交換する場合におけるリム交換補助装置11の動きの一例について説明する。交換に先立って、上下分割リム6Aでは、上リム4がリフタ5から離れて下リム3に載っていて、下リム3と回転軸2とのチャックは解除されている。 Hereinafter, an example of the movement of the rim replacement auxiliary device 11 when the upper and lower divided rims 6A attached to the rotating shaft 2 of the tire testing machine 1 are replaced will be described. Prior to the replacement, in the upper and lower divided rims 6A, the upper rim 4 is separated from the lifter 5 and rests on the lower rim 3, and the chuck between the lower rim 3 and the rotary shaft 2 is released.
まず、シャトル部13が、図1の待機位置からタイヤ試験機1へ向けて前進する。すると、タイヤ試験機1側のセット部17Aが、図2に示すように、上下分割リム6Aの下に潜り込む。この状態で縦移動部15が上昇することにより、上下分割リム6Aがすくい上げられて回転軸2から取り外される。その後、シャトル部13が図3に示すように待機位置まで後退してから、図4に示すように、回転部16が180度回転し、シャトル部13が、リムストッカー7へ向けてさらに後退する。すると、セット部17Aにセットされた上下分割リム6Aの真下に、リムストッカー7において受取位置にある空きの載置部10(図3参照)が配置されるので、縦移動部15が下降することにより、上下分割リム6Aが、この載置部10に載置される。 First, the shuttle unit 13 advances from the standby position in FIG. 1 toward the tire testing machine 1. Then, the set portion 17A on the tire testing machine 1 sinks under the upper and lower split rim 6A as shown in FIG. In this state, the vertical movement unit 15 is lifted, so that the upper and lower divided rims 6A are scooped up and removed from the rotary shaft 2. Thereafter, after the shuttle unit 13 is retracted to the standby position as shown in FIG. 3, the rotating unit 16 is rotated 180 degrees as shown in FIG. 4, and the shuttle unit 13 is further retracted toward the rim stocker 7. . Then, since the empty placing part 10 (see FIG. 3) at the receiving position in the rim stocker 7 is arranged directly below the upper and lower divided rims 6A set in the setting part 17A, the vertical movement part 15 is lowered. Thus, the upper and lower divided rims 6 </ b> A are placed on the placement unit 10.
その後、図5に示すようにシャトル部13が待機位置に戻るまでの間に、次の試験に使用する別サイズの上下分割リム6Bが受取位置に来るように、リムストッカー7の回転フレーム9が回転する。次に、図6に示すように、シャトル部13が、待機位置から上下分割リム6Bへ向けて後退し、セット部17Aが上下分割リム6Bの下に潜り込む。この状態で縦移動部15が上昇することにより、上下分割リム6Bがすくい上げられてリムストッカー7から取り外される。その後、図7に示すように、回転部16が180度回転し、シャトル部13がタイヤ試験機1へ向けて前進する。すると、図8に示すように、セット部17Aにセットされた上下分割リム6Bの真下に、タイヤ試験1の回転軸2が配置されるので、縦移動部15が下降することにより、上下分割リム6Bが、回転軸2に載置されてチャックされる。これにより、タイヤ試験機1では、上下分割リム6Aから上下分割リム6Bへの交換が完了する。 Thereafter, as shown in FIG. 5, the rotary frame 9 of the rim stocker 7 is moved so that the upper and lower divided rim 6B of another size used for the next test comes to the receiving position until the shuttle unit 13 returns to the standby position. Rotate. Next, as shown in FIG. 6, the shuttle unit 13 moves backward from the standby position toward the upper and lower divided rims 6B, and the set unit 17A enters under the upper and lower divided rims 6B. In this state, the vertical moving portion 15 is lifted, so that the upper and lower divided rims 6B are scooped up and removed from the rim stocker 7. Thereafter, as shown in FIG. 7, the rotating unit 16 rotates 180 degrees, and the shuttle unit 13 moves forward toward the tire testing machine 1. Then, as shown in FIG. 8, since the rotating shaft 2 of the tire test 1 is disposed directly below the upper and lower divided rims 6B set on the set portion 17A, the vertical moving portion 15 is lowered to move the upper and lower divided rims. 6B is placed on the rotating shaft 2 and chucked. Thereby, in tire testing machine 1, exchange from upper and lower division rim 6A to upper and lower division rim 6B is completed.
以上のように、リムストッカー7とは別に設けられたリム交換補助装置11が、セット部17にセットされた上下分割リム6を横移動部14によって横移動させたり、縦移動部15によって縦移動させたり、回転部16によって回転させたりすることによって、タイヤ試験機1とリムストッカー7との間で素早く受け渡す。そのため、タイヤ試験機1との間でのリムの受け渡しのためにリムストッカー7自体が移動しなくてもよいので、リムストッカー7は、タイヤ試験機1から離れた固定位置において、交換用の上下分割リム6を多数組(本実施形態の4組に限らず、6組や8組等)ストックすることができる。また、このようなリム交換補助装置11であれば、既存のタイヤ試験機1に後付けすることができる。これにより、上下分割リム6の交換に関する設備の設置について、省スペース化や簡便化を図れる。 As described above, the rim replacement auxiliary device 11 provided separately from the rim stocker 7 moves the upper and lower divided rims 6 set in the set unit 17 laterally by the laterally moving unit 14 or vertically by the longitudinally moving unit 15. Or by rotating by the rotating unit 16, the tire tester 1 and the rim stocker 7 are quickly transferred. Therefore, since the rim stocker 7 itself does not have to move for the transfer of the rim to and from the tire testing machine 1, the rim stocker 7 is installed at the upper and lower positions for replacement at a fixed position away from the tire testing machine 1. A large number of divided rims 6 (not limited to the four sets in the present embodiment, such as six sets or eight sets) can be stocked. Further, such a rim replacement assisting device 11 can be retrofitted to an existing tire testing machine 1. Thereby, about installation of the apparatus regarding replacement | exchange of the upper and lower division | segmentation rim 6, space saving and simplification can be aimed at.
この発明は、以上に説明した実施形態に限定されるものではなく、請求項に記載の範囲内において種々の変更が可能である。例えば、前述した実施形態では、上下分割リム6Aをリムストッカー7に移し終えてから交換用の上下分割リム6Bをリムストッカー7から取り出す。これに代え、上下分割リム6Aをタイヤ試験機1に取りに行く間に、上下分割リム6Bが受取位置に来ていて、その後に上下分割リム6Aがタイヤ試験機1からセット部17Aに受け渡された状態で、別のセット部17Bによって上下分割リム6Bをリムストッカー7から受け取ってもよい。これにより、リム交換に要する時間の更なる短縮を図れる。 The present invention is not limited to the embodiments described above, and various modifications can be made within the scope of the claims. For example, in the above-described embodiment, after the upper and lower divided rims 6 </ b> A have been transferred to the rim stocker 7, the replacement upper and lower divided rims 6 </ b> B are taken out from the rim stocker 7. Instead, the upper and lower divided rims 6B are in the receiving position while the upper and lower divided rims 6A are taken to the tire testing machine 1, and then the upper and lower divided rims 6A are transferred from the tire testing machine 1 to the set unit 17A. In this state, the upper and lower divided rims 6B may be received from the rim stocker 7 by another set portion 17B. Thereby, the time required for rim replacement can be further shortened.
