Holding apparatus for transport of conveyed items
First Claim
1. A holding apparatus for the transport of conveyable articles, particularly for the lifting, transportation and stacking of ferromagnetic conveying articles, said apparatus comprising:
- at least two permanent magnets for generating a permanent magnetic field, wherein the permanent magnets are arranged in the web in each case at the bottom, top or in a position in between;
at least two electric magnet coils, capable of being acted upon independently of one another either alternately or in the same direction, for generating a temporary magnetic field and for compensating for or intensifying the permanent magnetic field, and a magnetically conductive housing having two webs extending from a base plate, wherein, in each web at least one permanent magnet is capable of being screwed on, wherein the permanent magnets in each case are arranged;
in a magnetizing direction (M), at the rear, wherein on pole (N, S) on the housing forms a magnetic return, and at the front, with the other pole (S, N) in the direction of a working gap (AS) relative to the conveyable articles;
wherein the extension of the webs coincide with the respective magnetizing direction (M) of the permanent magnets; and
wherein the magnetic coils are arranged, in cross section, in the direction of the web extension, with their windings, one behind the other or one above the other, in at least one web interspace, so as to rise on the base plate; and
having a combined overall height which corresponds essentially to the length (L) of the webs; and
wherein there are (2n+1) or (n+1) webs (6), where n=1, 2, 3, permanent magnets in each case, wherein the webs are arranged in cross section lying respectively opposite one another in pairs in comparison with a central middle web.

Abstract
The invention relates to a holding apparatus for the transport of conveyed items, in particular the lifting, transporting, imbricating and stacking of ferromagnetic conveyed parts having at least two permanent magnets for generating a permanent magnetic field, at least two electrical magnet coils for generating a temporary magnetic field and compensation of the permanent magnetic field and a magnetically conductive housing. The permanent magnet is magnetized in the direction of its smallest dimension (l3) and is arranged in the direction of magnetization (M) at the rear with one pole (N, S) against the housing, forming a magnetic yoke, and at the front with the other pole (S, N) in the direction of a working clearance opposite the conveyed parts. The housing in cross section has three or more webs rising up from a baseplate and permanent magnets in each case fastened at the top in the region of the working clearance. In addition, at least two mutually independently energizable magnet coils are provided in at least one inter-web space.
