JIG CONVEYING DEVICE

PROBLEM TO BE SOLVED: To provide a jig conveying device that automatically rejects a direction- failure jig, corrects the direction failure, and supplies and conveys the jig. SOLUTION: The jig conveying device comprises a traveling passage 4 allowing a cylindrical body 5 to travel in a standing state, a first conveying passage 6 for conveying the cylindrical body 5 branching from the traveling passage 4 to an engaging/mounting position 7, a detecting means 8 that is disposed at the tip in the traveling direction of the first conveying passage 6 and detects the direction of the cylindrical body 5 transferred and conveyed from the first conveying passage 6, a pressing means 9 for pressing a direction-failure cylindrical body 5' corresponding to the detection by the detecting means 8, a discharging means 10 that is elastically opened by pressing of the pressing means 9 and discharges the direction-failure cylindrical body 5' from the passage 6, a second conveying passage 11 for transferring the discharged cylindrical body 5' in a transverse state and conveying it, a changing means 11' for rotating and changing by 90 deg. a conveying direction of the cylindrical body 5' transferred to the second conveying passage 11, a direction normalizing means 12 for returning the cylindrical body 5' changed in conveying direction from the transverse state to the normal standing state, and a third conveying passage 13 for returning the normalized cylindrical body 5 to the running passage 4.
