レール16,16を敷設し、ハンガーに揺れが生じたときに
この補助走行レール16,16の下面に接触する一対の揺れ
止めローラ17,17をハンガー11に設けてある。When the self-propelled carrying device 10 travels in the direction of arrow A, the hanger 11 is in a direction perpendicular to the traveling direction (arrow B).
In order to sway (roll) in a direction), a pair of auxiliary traveling rails 16 and 16 are laid as both sides of the main traveling rail R below the main traveling rail R, and the auxiliary traveling rails 16 and 16 are laid when the hanger is shaken. The hanger 11 is provided with a pair of anti-sway rollers 17 and 17 that come into contact with the lower surface of the hanger 16.

せることにより駆動車輪の走行摩擦駆動力を増大させる
ためである。The reason why the pair of anti-sway rollers 17 and 17 are not supported on the upper surfaces of the auxiliary traveling rails 16 and 16 and are in contact with the lower surfaces of the rollers 16 and 16 is to load the entire suspension load of the hanger on the drive wheels 13. This is to increase the traveling friction drive force of the drive wheels.
ところが、このような揺れ止め機構15によると、揺れ
止めローラ17は、駆動車輪13及び従動車輪14とで主走行

なり、駆動車輪13は搬送装置10を走行させることができ
なくなるという問題点がある。However, according to such an anti-sway mechanism 15, the anti-sway rollers 17 are formed on the driving wheels 13 and the driven wheels 14 from the upper surface of the main traveling rail R and the lower surface of the auxiliary traveling rail 16 to both rails.
Since there is a positional relationship of sandwiching R and 16, when the anti-sway roller 17 is strongly pressed against the auxiliary traveling rail 16, the traveling resistance becomes large, and the drive wheels 13 cannot drive the transport device 10. There is.
このため、揺れ止めローラ17と補助走行レール16の間
に隙間Ｓを設ける必要があるが、そうすると、この隙間
分だけハンガー11が揺れるという問題点が生じる。For this reason, it is necessary to provide a gap S between the anti-sway roller 17 and the auxiliary traveling rail 16, but this causes a problem that the hanger 11 shakes by the amount of this gap.

強圧されることはない。Action The transport device loads the transported items on the hanger and runs on the main traveling rail and the auxiliary traveling rail. At this time, the drive wheels travel on the main traveling rail, and the pair of auxiliary traveling rollers travel on the upper surfaces of the pair of auxiliary traveling rails. Since the load of the conveyed product is supported by the drive wheel at the center and the pair of left and right auxiliary traveling rollers on both sides below the drive wheel, the hanger does not swing and the drive wheel is not driven. Since both and the auxiliary traveling rollers are supported on the upper surfaces of both rails, both rails are not in a positional relationship of being sandwiched by the drive wheel and the auxiliary traveling rollers, so that the auxiliary traveling rollers are not strongly pressed by the auxiliary traveling rails.
さらに、ハンガーは走行フレーム上の駆動輪の下方位

で、ハンガーの搬送荷重の相当部分は直接駆動輪に負荷
されるので駆動輪の摩擦駆動力を充分に得られる。Furthermore, since the hanger is suspended vertically in a position below the drive wheels on the traveling frame so that it can swing in the vertical direction, a considerable portion of the hanger's carrying load is directly applied to the drive wheels, so friction drive of the drive wheels is performed. You can get enough power.
