    摘要： A magnetic substance holding device according to an exemplary embodiment of the present invention includes: a first pole piece assembly including a first N-pole piece, a first S-pole piece, and a first permanent magnet; a second pole piece assembly including a second N-pole piece, a second S-pole piece, and a second permanent magnet; at least one first coil; at least one second coil; and a control device controlling current applied to the first coil and the second coil. At least one of the first pole piece assembly and the second pole piece assembly is movable so that a first arrangement in which the contact face of the first N-pole piece is separated from the contact face of the second S-pole piece and the contact face of the first S-pole piece is separated from the contact face of the second N-pole piece, and a second arrangement in which the contact face of the first N-pole piece comes in contact with the contact face of the second S-pole piece and the contact face of the first S-pole piece comes in contact with the contact face of the second N-pole piece are switched between each other. The control device adjusts current applied to the first coil and the second coil so as to control magnetic fluxes passing through the first coil and the second coil, thereby allowing the first pole piece assembly and the second pole piece assembly to switch between the first arrangement and the second arrangement, to control magnetic fluxes passing through the holding faces of the first pole piece assembly and the second pole piece assembly.

    摘要： Disclosed herein is a magnetic substance holding device that minimizes residual magnetism by way of employing structures for minimizing reluctance to magnetic flux flow.
    The magnetic substance holding device comprises: a first pole piece having a holding face on which the workpiece is attached and a base-attaching face at different portion from the holding face, the first pole piece being a magnetic substance; a second pole piece having a holding face on which the workpiece is attached and a base-attaching face at different portion from the holding face, the second pole piece being a magnetic substance; a primary permanent magnet disposed so that its N-pole comes in contact with the first pole piece or the second pole piece while its S-pole comes in contact with the second pole piece or the first pole piece; a base configured to movae between a first location and a second location, the base being spaced apart from at least one of the base-attaching face of the first pole piece and the base-attaching face of the second pole piece at the first location while the base being in contact with both of the base-attaching face of the first pole piece and the base-attaching face of the second pole piece at the second location; at least one coil wound around at least one of the first pole piece, the second pole piece and the base; and a control device controlling electric current applied to the coil to magnetize at least one of the first pole piece, the second pole piece and the base, thereby controlling holding or detaching of the workpiece, wherein: upon the base being placed at the first location, the workpiece is attached on the holding faces of the first and second pole pieces, upon applying electric current to the coil to create magnetic flux flow passing through the base-attaching face of the first pole piece and the base-attaching face of the second pole piece, the base is placed at the second location by magnetic force, so that the workpiece is detached from the holding faces of the first and second pole pieces, a flow-promoting portion is formed near a region where the first pole piece meets the base or a region where the second pole piece meets the base so that when the base is at the second location, the shortest one of magnetic flux paths induced by the primary permanent magnet and passing through the base is not bent at a right angle, and corners of the base are chamfered or filleted for conforming to magnetic flux path induced by the primary permanent magnet and passing though the base when the base is at the second location.

    摘要： The present invention relates to a magnet (100), which comprises a body (101) and a slide (110) that is arranged to be movable relative to the body (101). The slide (110) comprises a permanent magnet (111), and a first and a second pole piece (112, 113) that are attached to opposite magnetic pole surfaces of the permanent magnet (111). The body (101) comprises a first and a second section (103, 104) made of magnetic material for directing magnetic flux to an object (200) to be attached. The first and the second section (103, 104) are separated and attached to a third section (105) of the body (101), which third section (105) is made of non-magnetic material. The first section (103) comprises a hole (106) that opens at a first end into a first cavity (107) and at a second end into a second cavity (108) of the body (101), the first and the second cavity (107, 108) containing a medium. The magnet (100) further comprises means (116, 117, 118, 119, 120) for transferring the medium into and out of the first and the second cavity (107, 108) in order to move the slide (110) that is movably arranged in the hole (106). The invention also relates to a method for handling metal sheets (200).

    摘要： There is provided a magnetic clamping device (10) for magnetically clamping to a magnetically attracted material (30). The device comprises at least one permanent clamping magnet (14, 44) for magnetically clamping to the magnetically attracted material wherein the magnet is movable relative to the magnetically attracted material from a position remote from the magnetically attracted material to a clamping position for the clamping of the material by the magnet. The device also includes damping means (22, 24) for damping the movement of the clamping magnet to the clamping position. The damping means biases the clamping magnet away from the magnetically attracted material to assist release of the clamping magnet from the magnetically attracted material. In addition, the device has support means (16, 40, 58) to which the clamping magnet is mounted for the relative movement of the clamping magnet from the remote position to the clamping position and for withdrawing the clamping magnet relative to the magnetically attracted material to release the magnetically attracted material. There is also provided a method for clamping the magnetically attracted material (30) using the clamping device (10). The clamping device may, for example, be a device for securing a load to the magnetically attracted material, a lifting device, a device for holding a work piece in position, or a welding clamp.

    摘要： An exemplary locking or coupling device includes a plurality of magnets each having a direction of magnetization. A plurality of pole shoe members are positioned between selected ones of the magnets. A moveable support supports some of the magnets and some of the pole shoe members. The moveable support is moveable to selectively change a relative orientation of the directions of magnetization. One relative orientation primarily directs a flow of magnetic flux between the magnets through the pole shoe members and the magnetic flux remains essentially in a plane containing the magnets and the pole shoe members. A second, different relative orientation primarily directs the flow of magnetic flux from the pole shoe members in a transverse direction away from the plane.
