In a transfer system using movable bodies supported and guided by a rail through a plurality of guided devices so that they are capable of moving in a given path, when a movable body taken out from the given path is transferred to a separate given path or restored to the original given path, the movable body needs be separated or joined while being longitudinally moved, thus requiring a long path for separating or joining. The invention provides a system comprising a group of guided devices relatively turnably connected to main bodies of the movable bodies through vertical shafts, a plurality of divisional rail bodies capable of supporting the group of guided devices and disposed in a set path portion in the given path, turning means for turning these divisional rail bodies around vertical axes, and a group of transverse rail bodies disposed laterally of the set path portion such that the divisional rail bodies turned for separation from the rail can be connected. Consequently, the movable body can be transversely separated from and joined to the given path.
A transfer system using movable bodies that are supported and guided on a rail through a plurality of guided devices disposed on main bodies of the movable bodies so that the movable bodies are movable in a given path, the main bodies being provided with supports for a transfer subject, wherein
A transfer system using movable bodies, in which the movable bodies are supported and guided by a rail through a plurality of guided devices so that they are movable in a given path, the movable body having a main body composed of a plurality of frame bodies horizontally connected to be relatively turnable through connecting devices, at least one of said frame bodies being provided with a support section for transfer subjects, wherein

The preset invention relates to a transfer system using movable bodies in moving the movable bodies, which is used to transfer subjects, for example, in a given path on the floor or ceiling.
Heretofore, as for this type of movable body, there has been provided an arrangement found in Japanese Patent Laid-Open No. 7-25441, for example. That is, a movable body movable in a given path as supported and guided by a rail has a main body composed of three frame bodies relatively turnably connected through connecting devices. And each frame body is in the form of a quadrangular body extending in the direction of the given path, with its side surface being formed as a driven surface. The intermediate frame body included in the frame body is provided with a support section for transfer subjects, and guided device to be supported and guided by the rail. Further, the two frame bodies, front and rear, are provided with guided devices to be supported and guided by the rail.
According to the conventional arrangement described above, however, in transferring the movable body to a different given path or returning to the original given path after it has been taken out of the given path, for example, the movable body has to be moved for separating or joining while moving the movable body in the longitudinal direction, thus requiring a long path for separating or joining. Further, when a storage path is formed in the given path to store the movable body, for example, the storage path will be long in length according to the number of storages since this movable body is stored with each frame body put in rectilinear form.
FIG. 1 is a side view of a divisional rail body portion, before turning, in a transfer system using movable bodies, according to a first embodiment of the invention;
FIG. 2 is a side view of the divisional rail body portion, after turning, in the transfer system using movable bodies;
FIG. 3 is a plan view, partly broken away, of the divisional rail body portion, before turning, in the transfer system using movable bodies;
A first embodiment of the invention will now be descried with reference to FIGS. 1 through 17, with movable bodies employed for an overhead traveling type.
In FIGS. 7 through 13, a rail 2 that is I-shaped in section is laid on a machine frame 1 from the ceiling. The rail 2 defines a given path 5 that, as seen in a plan view, is composed, for example, of a rectilinear operating path portion 5a, a rectilinear return path portion (an example of a set path portion) 5c connected to the terminal end of the operating path portion 5a through a curved path portion 5b and the like.
Further, this portion of the return path portion 5c is formed with a transverse path portion 6 orthogonal thereto. And this transverse path portion 6 is formed with a different given path 5A orthogonal thereto and parallel with the return path portion 5c, the given path 5A being composed of a rail 2A that is similarly I-shaped in section and the like.
