Abstract

주행차가 왕복주행하는 영역의 양 끝단중, 한쪽의 끝단부에 있어서, 주행차가 직진주행으로부터 후진주행으로 옮길 때에, 그대로 곧바로 되돌아갈 수 있도록 하는 자재차륜의 방향변향장치를 제공한다.Provided is a direction change device for a material wheel that allows the traveling vehicle to return immediately as it is when the traveling vehicle moves from a straight run to a backward run at both ends of an area in which the traveling car reciprocates.

방향변향장치(20)는, 자재차륜(21)에 지지되어 바닥(G)을 주행하는 주행차(23)를 바닥에서 밀어올리는 밀어올림수단(25)을 가지며, 자재차륜을 주행차에 한 끝단이 수평축(30)으로 축지지되고 자유단이 주행차가 밀어올려졌을 때 주행차로부터 아래방향으로 떨어지는 경사이동판(26)을 구비한 구성으로 되어 있다.The direction change apparatus 20 has the pushing means 25 which pushes the traveling vehicle 23 which is supported by the material wheel 21 and runs the floor G from the floor, and the end which made the material wheel to the traveling car. The inclined moving plate 26 is supported by the horizontal shaft 30 and the free end falls downward from the traveling vehicle when the traveling vehicle is pushed up.

주행차는, 직진주행으로부터 후진주행으로 옮길 때에, 밀어올림수단에 의하여 바닥에서 밀어올려진다. 그러면 경사이동판이 수평축을 중심으로 하여 아래쪽으로 기울고, 자재차륜의 차륜이 자중에 의하여 경사이동판의 하단쪽으로 회전하여 이동함으로써 방향이 바뀐다.The traveling vehicle is pushed from the floor by the pushing means when moving from the straight run to the backward run. Then, the inclined movable plate is inclined downward with respect to the horizontal axis, and the wheel of the material wheel is rotated toward the lower end of the inclined movable plate by its own weight to change direction.

그 후, 주행차를 하강시키면, 자재차륜은 방향이 바뀐 상태로 주행차를 지지하여 주행차를 좌우로 흔들리는 일 없이 후진주행 안내를 한다.Then, when the driving vehicle is lowered, the material wheels support the driving vehicle in a changed direction and guide the reverse driving without shaking the driving vehicle from side to side.
