Abstract
An overhead transport carriage 1 comprises a body 4 containing an object 30 and traveling along a traveling rail 3, a lifting mechanism 6 including a holding unit 8 holding the object 30 and a lifting unit 7 moving the unit 8 up and down with respect to a predetermined position P at which the object 30 is contained, an anti lid-dropping-off member 20 facing a lid 31 of the object 30 when the unit 8 is located at the position P, and a moving mechanism. The mechanism 10 moves the member 20 in response to the motion of the unit 8 so that the member 20 is located at an anti dropping-off position when the unit 8 is located at the position P, and the member 20 is located at the escape position when the unit 8 moves with respect to the position P.
Claims8
An overhead transport carriage conveying an object to be conveyed with a detachable lid along a conveying route, the overhead transport carriage comprising:
- a body containing the object to be conveyed and traveling along the conveying route;
- a lifting mechanism including a holding unit holding the object to be conveyed and a lifting unit moving the holding unit up and down with respect to a predetermined position at which the object to be conveyed is contained;
- an anti lid-dropping-off member facing the lid when the holding unit is located at the predetermined position;
- and
- a moving mechanism moving the anti lid-dropping-off member in response to up-and-down motion of the holding unit so that the anti lid-dropping-off member is located at a first position for preventing the lid from dropping off when the holding unit is located at the predetermined position and the anti lid-dropping-off member is located at a second position farther from the lid than the first position when the holding unit moves up and down with respect to the predetermined position, wherein
- the moving mechanism includes a receiving part that is connected to the anti lid-dropping-off member and on which the holding unit abuts when the holding unit is located at the predetermined position, and
- by the abutment of the holding unit against the receiving part, the moving mechanism moves the anti lid-dropping-off member to the first position when the holding unit moves up to the predetermined position and lifts the receiving part, and moves the anti lid-dropping-off member to the second position when the holding unit moves down from the predetermined position and leaves the receiving part.
