〔Example〕

The structure of the self-locking joint for a ceiling-suspended carrier machine of the present invention will be explained according to the illustrated example.As shown in FIG. A joint housing 2 is attached, and the joint housing 2 is provided with a self-locking pawl 3 and a link 5 or an arm 7 so as not to be rotatable via a hinge 4.

Furthermore, a T-shaped hanger 8 and a guide roller 9 for a lifter are provided on the conveyed object side. A lifter device 10 and a locking/unlocking cylinder 11 are provided at fixed positions on the side of the conveyance path, and the self-locking claw of the T-shaped hanging tool 8 is locked by the locking/unlocking cylinder 11. 3 is released from the locked state, and at the same time, the lifter device 10 allows the member on the conveyance side to move up and down.

As shown in FIG. 2, the joint housing 2 of the present invention is provided with a pair of left and right self-locking pawls 3 slidably via respective hinges 4. 3, 3 fixes the T-shaped hanger 8, and connects the main body 1 of the ceiling-hanging type conveyor and the conveyed object so that they can move as one. Also,
When the cylinder 11 is actuated and the arm 7 is swung through the hinge 4, the pair of self-locking claws 3, 3 move from the state of locking the T-shaped hanger 8 to the position of releasing the engagement. Move and become unlocked.

First, as the ceiling-suspended conveyor of the present invention moves, when the conveyor body 1 is on the lifter device 10, as shown by the solid line in FIG. When the conveyed object is a target for predetermined processing, the conveyor main body 1 is stopped by a device (not shown), and the lifter device 1 is stopped.
