A conveying device drivable by rack gear has a towed hook further forward than a front end of a rack gear mounted to a conveying traveling body. A driving pinion gear, disposed at an entrance of a rack gear drive section, has a drawing-in claw that engages the towed hook and draws in the conveying traveling body to a position where the front end of the rack gear meshes with the driving pinion gear. The towed hook has, at a position at a rear side of a hook portion at a distal end thereof and further forward than the front end of the rack gear, an advance preventing claw portion disposed continuous thereto that, together with the hook portion, sandwiches the drawing-in claw, and the hook portion has a length such that it enters more deeply inside a rotation locus of the drawing-in claw than the advance preventing claw portion.

Conveying device drivable by rack gear

A suspension conveying device according to the present invention includes screw shafts of two suspension line pulling-up/feeding mechanisms in a conveying traveling body. The screw shafts have low-speed drive regions, in which feed pitches for driven bodies are small, and high-speed drive regions, in which feed pitches for the driven bodies are large. The screw shafts are installed so that the low-speed drive regions and the high-speed drive regions are disposed mutually oppositely as viewed from the driven bodies when a conveyed object supporter is at one end of an elevation/lowering stroke, and the conveyed object supporter is tilted in a middle of the elevation/lowering stroke when the screw shafts are driven to undergo forward/reverse rotation at a fixed speed by a motor.

Suspension conveying device

A slat conveyor has a plurality of slat bodies supported between a pair of left and right driving endless turning bodies by concentric horizontal support shafts and has a pair of front and rear guide rollers supported to a guide rail laid on each of upper and lower horizontal path sections. A U-turn guiding mechanism at both ends includes the guide rollers, a slat body posture controlling rotating body, and a drive mechanism for the rotating body. The rotating body has the same turning radius as that of the horizontal support shaft on a U-turn path section, and includes an engaging portion for positioning and turning the guide rollers. The drive mechanism drives the rotating body such that the engaging portion is turned in the same direction and at the same speed as the turning speed of the horizontal support shaft on the U-turn path section.

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.

Transfer system using movable bodies

A conveyor comprises a plurality of carriages , each including a deck having a friction surface for a primary drive, which is formed on or near one side of the deck , and is parallel to the direction in which the carriages travel. Each carriage also includes a bar fitted on the underside of the deck and extending on the centerline of the deck. The bar has a friction surface for a secondary drive. The travel path includes a linear primary travel line and a secondary travel line for carriage return. A primary drive , is arranged for contact with the friction surfaces . The secondary travel line is fitted with a plurality of drives A and B at intervals, for secondary propulsion in the return direction.
