Embodiment Construction

[0078] The RSM has various preferred embodiments described herein. However, invariably, the steps to implement different embodiments of the present invention are the same. Steps to accomplish the various embodiments of the invention include: design and operational considerations; selecting the size and shape of the permanent magnets; determining friction reducing members; matching pole tubes; designing the core elements;

[0079] Design and Operational Considerations

[0080] The highly flexible structure of the present invention enables rapid configuration of the device that best suits the application or end product design. By combining the desired grip strength, holding position, and offset load (moment) with characteristics typical of the desired goals, it can help to select the appropriate components needed in the RSM to achieve these goals. Target specifications such as material, thickness, composition, finish, stiffness, size and weight need to be determined in advan...

Abstract

A method for creating and a device for a rotary switchable multi-core element, permanent magnet-based apparatus, for holding or lifting a target, comprised of two or more carrier platters, each containing a plurality of complementary first and second core elements. Each core element comprises permanent magnet(s) with magnetically matched soft steel pole conduits attached to the north and south poles of the magnet(s). Core elements are oriented within adjacent carrier platters such that relative rotation allows for alignment in-phase or out-of-phase of the magnetic north and south fields within the pole conduits. Aligning a first core element "in-phase" with a second core element, that is, north-north / south-south, activates that core element pair, allowing the combined magnetic fields of the pole conduits to be directed into a target. Aligning the core element pair "out-of-phase," that is, north-south / south-north, deactivates that core element pair by containing opposing fields within the pole conduits.

Description

technical field [0001] Artificially activated magnetic fields in permanent magnetic chucks, grippers and lifting devices have been used on ferromagnetic materials (targets) for decades. Its routine use can be found in mills, pulverizers, lathes, drills, and other industrial and commercial installations. Other applications include fixtures, tool and gage holders, material alignment, and clamps. A variety of magnet-based lifters are used in material handling and robotic pick-and-place installations. Unfortunately, most switchable permanent magnet arrays are expensive, difficult to produce, structurally fragile, or relatively heavy. Therefore, the use of switchable permanent magnet arrays is very limited in commercial and retail markets. Excessive expense has greatly hindered the integration of switchable permanent magnet arrays into end-user products. Attempts have been made to use these devices for automating fixtures and elevators, but the cost and difficulty of automating...
