次に前記上部シリンダー１１ａ、１１ｂを作動させて、前記第３支柱６ａ及び前記第４支柱６ｂがそれぞれ前記保持テーブル２に設けた長孔４内を外方に移動するようにし、これら支柱６ａ、６ｂを保持テーブル２上のホイールＡのリム部の内周側に図１の点線図示の如く当接させて該ホイールＡを確実に保持するようにする。   Next, the upper cylinders 11a and 11b are operated so that the third support column 6a and the fourth support column 6b move outward in the long holes 4 provided in the holding table 2, respectively. 6b is brought into contact with the inner peripheral side of the rim portion of the wheel A on the holding table 2 as shown by the dotted line in FIG. 1 so that the wheel A is securely held.

次いで前記ホイールＡの上にタイヤを載置し、昇降シリンダー８の作動により昇降板９を更に上昇すると、これに伴って天板１０は保持テーブル２を載置したまま更に上昇し、図７の如く側板２ａ、２ｂの下端はベース板７の上面から離れる。このとき支柱５ａ、５ｂ、６ａ、６ｂはその上端部が保持テーブル２の上面より突出してホイールＡを保持した状態である。   Next, when a tire is placed on the wheel A and the elevating plate 9 is further raised by the operation of the elevating cylinder 8, the top plate 10 is further raised while the holding table 2 is placed, as shown in FIG. Thus, the lower ends of the side plates 2 a and 2 b are separated from the upper surface of the base plate 7. At this time, the columns 5a, 5b, 6a, 6b are in a state in which the upper ends thereof protrude from the upper surface of the holding table 2 to hold the wheel A.

保持テーブル２の上昇により、テンションローラ２０の先端部がホイールＡのリム部とタイヤのビード部の間に介入して該テンションローラ２０により該ビード部を外方に拡張すると共にダンピングローラ２１を降下して該タイヤのサイドウオール部を押圧しながら、これらテンションローラ２０とダンピングローラ２１をホイールＡの外周に沿って回転してタイヤをホイールＡにマウントする。   As the holding table 2 rises, the tip of the tension roller 20 intervenes between the rim portion of the wheel A and the bead portion of the tire, and the bead portion is expanded outward by the tension roller 20 and the damping roller 21 is lowered. Then, the tire is mounted on the wheel A by rotating the tension roller 20 and the damping roller 21 along the outer periphery of the wheel A while pressing the side wall portion of the tire.

次に下部シリンダー１６ａ、１６ｂを作動させて第１、第２支柱５ａ、５ｂをホイールＡから遠ざけ、更に上部シリンダー１１ａ、１１ｂを作動させて、第３支柱６ａと第４支柱６ｂを長孔４内を内方に移動してから保持テーブル２を降下させて、第１乃至第４支柱５ａ、５ｂ、６ａ、６ｂを保持テーブル２の長溝３及び長孔４内に没入した状態にしてから、搬送装置（図示せず）により組み上ったホイールをホイール保持装置１の外方に移動し、次のホイールをホイール自動供給装置によりホイール保持装置１に供給して前述の作動を繰り返す。   Next, the lower cylinders 16a and 16b are operated to move the first and second support columns 5a and 5b away from the wheel A, and the upper cylinders 11a and 11b are further operated to connect the third support column 6a and the fourth support column 6b to the long hole 4. After moving the inside inward, the holding table 2 is lowered, and the first to fourth columns 5a, 5b, 6a, 6b are immersed in the long grooves 3 and the long holes 4 of the holding table 2, The wheel assembled by the transport device (not shown) is moved to the outside of the wheel holding device 1, the next wheel is supplied to the wheel holding device 1 by the automatic wheel supply device, and the above operation is repeated.

このように、保持テーブル２と天板１０が当接しているときは、支柱５ａ、５ｂ、６ａ、６ｂが該保持テーブル２の上面より突出するように、又保持テーブル２と天板１０とが前述の如く間隙ｔ離れたときは、支柱５ａ、５ｂ、６ａ、６ｂの上端部が保持テーブル２の上面より下方に位置して保持テーブル２の長溝３や長孔４内に没入するように、連結板１７ａ、１７ｂ、１８ａ、１８ｂを介して、支持筒体１２ａ、１２ｂ、１４ａ、１４ｂ等を支持ブラケット９ａ、９ｂの所定の上下位置にそれぞれ横設されている。   As described above, when the holding table 2 and the top plate 10 are in contact with each other, the columns 5a, 5b, 6a and 6b protrude from the upper surface of the holding table 2 and the holding table 2 and the top plate 10 are When the gap t is separated as described above, the upper ends of the columns 5a, 5b, 6a, 6b are positioned below the upper surface of the holding table 2 so as to be immersed in the long grooves 3 and the long holes 4 of the holding table 2. The support cylinders 12a, 12b, 14a, 14b and the like are horizontally provided at predetermined vertical positions of the support brackets 9a, 9b via the connecting plates 17a, 17b, 18a, 18b.

本発明のホイール保持装置は、センターコーンによるホイールＡの押圧工程がないので、ホイールＡに塗装剥離等の心配がなく、又、タイヤをホイールにマウントする全工程の自動化が容易なので、低コストでホイールにタイヤをマウントすることができ、特に偏平タイヤ或いはランフィットタイヤをホイールにマウントする作業にも適している。   Since the wheel holding device of the present invention does not have a pressing process of the wheel A by the center cone, there is no worry about paint peeling on the wheel A, and the whole process of mounting the tire on the wheel is easy to automate, so the cost is low. A tire can be mounted on a wheel, and is particularly suitable for an operation of mounting a flat tire or a run-fit tire on a wheel.

本発明のタイヤマウンターのホイール保持装置は自動車の製造ライン或いは自動車の整備工場等で使用される。   The wheel mounter for a tire mounter of the present invention is used in an automobile production line, an automobile maintenance shop, or the like.
