<p>PURPOSE:To convey workpieces in a hopper one by one separately by means of a magnet type belt conveyor. CONSTITUTION:A pair of electromagnets 44, 46 are separately arranged in the vertical direction in the back of a conveyor belt 40. In the case where workpieces in a hopper 10 are being attracted to the conveyor belt 40 to be conveyed upward, when a top workpiece reaches a position where it is to be attracted by the upper electromagnet 44 and a sensor 56 is turned on, magnetization of the lower electromagnet 46 is released so that a workpiece which has been attracted by the electromagnet 46 is dropped inside the hopper 10.</p> |
