<p>A magnetic roller conveyor for transporting magnetically conductive objects comprises at least two magnetically conductive rollers and at least two pairs of permanent magnets each located adjacent to and connected with the respective axial end portions of the respective rollers. The magnets of the same pair of magnets are polarized differently with respect to each other, whereas the magnets connected to the same roller are polarized identically with respect to each other. The rollers and the magnets connected thereto form together a magnetically closed path. The rollers are rotatably mounted on magnetically conductive shafts which latter also form a part of the above magnetically closed path. A second magnet system may be provided which is mirror-inverted with respect to the above mentioned first magnetic system so that force of attraction of the rollers is doubled. Switching members are further provided operative for demagnetizing and subsequently remagnetizing-of the rollers.</p> |
