Title:
LIFTER MAGNET
Document Type and Number:
Japanese Patent JP3440370
Kind Code:
B
Abstract:
PURPOSE: To obtain larger attracting force by constituting each attracting body of integrated attracting pieces provided side by side in the state of being relatively movable in the vertical direction and spaced from each other.
CONSTITUTION: A lifter magnet 6 fitted to an arm in a conveyor for conveying a workpiece from a preparation place into a conveyed place near a pressing device has attracting bodies B on both lateral sides of a body A, and the body A is constituted of a main body part A1 and a holding part A2 for holding the attracting body B in the attached state to the main body part A1. Each attracting body B is provided with a first and a second attracting pieces 41, 42 in order to obtain integrated workpiece attracting magnetic poles 43, 44 magnetized respectively to unlike poles. The respective attracting pieces 41, 42 are relatively movable in the vertical direction according to the height of the surface of the workpiece even with unevenness, and the respective attracting magnetic poles 43, 44 come in appropriate contact with the upper face of the workpiece.
