A drive device having a transmission body that can be freely engaged and disengaged is provided.

[0007]

According to the structure of the present invention, the moving body supported and guided by the rail device is moved by receiving the driving force of the driving device by the engagement between the passive body and the transmission. When the preceding moving body has stopped forward, the passive body and the transmission body are disengaged by the action of the detachment operation tool of the preceding moving body, and the succeeding moving body is stopped in a non-passive state. In the moving body that supports the transported object during such a transport operation, each trolley is supported and guided by the main rail, and each connecting rod is linearly positioned.

Then, the moving body reaches the actual moving body storage unit, and the preceding three trolleys are supported and guided by the main rail, while the rear trolley is supported and guided by the first sub-rail, so that the actual moving body is The rear connecting rod is stored in a posture in which the rear connecting rod is bent at a predetermined angle with respect to the front connecting rod and the intermediate connecting rod which are linearly located. At this time, the engagement between the passive body and the transmission body is released by the action of the detachment operation tool of the third trolley in the preceding moving body, and the succeeding moving body is stopped in a non-passive state. At that time, the stop pitch is determined by the added length of the front connecting rod and the intermediate connecting rod.

Therefore, a long object to be transported having a large width is
It is moved in the actual mobile storage unit while being inclined at a predetermined angle and with the side surfaces approaching each other. Thereby, the total length of the actual moving body can be shortened according to the inclination.
The angle of inclination can be set arbitrarily according to the interval between both rails and the length of the rear connecting rod.

The rear trolley is supported and guided by the rail and the rear trolley is supported and guided by the first sub-rail, so that the moving body is bent at a predetermined angle with respect to the front connecting rod by the intermediate connecting rod and the rear connecting rod. It is stored in a posture located linearly.

At this time, the operation of the second trolley detaching operation tool in the preceding moving body disengages the passive body and the transmission body, and the succeeding moving body is stopped in a non-passive state. At that time, the stop pitch is determined by the length of the front connecting rod. Therefore, the support device having a predetermined width is moved in the empty moving body storage unit while being inclined at a predetermined angle and with the side surfaces approaching each other. Thereby, the total length of the empty moving body can be shortened according to the inclination.

Note that the rear trolley merges with the main rail when exiting the real mobile storage unit, and the third trolley merges with the main rail when exiting the empty mobile storage unit. Thus, each connecting rod of the moving body is positioned linearly again.
