PROBLEM TO BE SOLVED: To convert a conveyance condition of an object to be conveyed in a first conveyance passage to a conveyance condition thereof in a second conveyance passage simply and speedily when the object to be conveyed is transferred from the first conveyance passage to the second conveyance passage by arranging a magnet in a boundary part of the first conveyance passage and the second conveyance passage to control magnetic force applied to the boundary part from the magnet. SOLUTION: A magnet 13 on a first conveyance passage side and a magnet 23 on a second conveyance passage side which are constituted by permanent magnets and air cylinders 14, 24 for driving which move each magnet 13, 23 vertically are provided in a boundary part A of a first conveyance passage 12a and a second conveyance passage 22a to transfer a magnetic workpiece 1 from the first conveyance passage 12a to the second conveyance passage 22a. By moving the magnets 13, 23 vertically through the air cylinders 14, 24 to control the magnetic force applied to the boundary part A adequately, a conveyance form of the first conveyance passage 12a and the second conveyance passage 22a can be efficiently converted in all cases of a combination of continuous feeds, a combination of intermittent feeds, or a combination of a continuous feed and an intermittent feed. |
