PORTABLE MAGNETIZER SYSTEMS

BACKGROUND

This invention relates to providing a system for a portable magnetizer. More particularly this invention relates to providing a portable system for magnetizing batches of magnetizable sheets.

Magnetizing of magnetizable sheeting is either conducted during manufacture or in large production lines. When only a small batch of sheets needs magnetizing, it is inefficient to utilize large scale methods of magnetization. A high-volume production magnetizer is expensive and may take up too much space for the benefit of smaller scale, occasional use on-site. Likewise, taking a batch of sheets in to a high-volume production company for magnetization slows down production and consequently the high-volume production company charges increased fees. A system is needed to magnetize on-site, for less cost, in a portable and space saving manner.

DETAILED DESCRIPTION OF THE BEST MODES AND PREFERRED EMBODIMENTS OF THE INVENTION

Magnetizeable sheets preferably comprise a printable surface that allows them to be printed on by standard printers. These magnetizable sheets can cause problems with printers when they are run through the printer after magnetization, since a magnetic field may interfere with the operability of the printer. One solution to this problem is to print on the printable side of the magnetizable sheets prior to magnetization. The sheets would then not interfere with printer function, and after printing, the sheet may then be run through a magnetizer.

FIG. 20 shows a partial-exploded perspective view illustrating at least one high-energy portable magnetizer 400 according to an alternately preferred embodiment of the present invention. As many of the elements of high-energy portable magnetizer 400 are preferably retained from portable magnetizer 105, only structures and arrangements on the present embodiment, differing from the prior embodiment, will be elaborated upon.

Preferably, high-energy portable magnetizer 400 replaces magnetizer array assembly 205 of portable magnetizer 105 with at least one high-energy magnetizer array assembly 405. High-energy magnetizer array assembly 405 preferably comprises at least one upper magnetic field source 445 and at least one lower magnetic field source 455, as diagrammatically shown in FIG. 21.

FIG. 21 shows a diagrammatic side view, illustrating at least one feed path 430 extending through high-energy magnetizer array assembly 405, according to the preferred embodiment of FIG. 20.

FIG. 23 shows an isometric exploded view, illustrating the preferred arrangements of upper magnetic bar assembly 440, according to the preferred embodiment of FIG. 22. Reference is now made to FIG. 21 and FIG. 22 with continued reference to FIG. 20 and FIG. 21. The upper magnetic bar assembly 440 preferably comprises at least one upper magnetizer array subassembly 510, more preferably at least two magnetizer array subassemblies 510, as shown. Magnetic bar assembly 440 preferably comprises at least one smooth outer casing 460 and preferably comprises at least one magnetic stack 465, preferably contained within outer casing 460, as shown. Outer casing 460 preferably comprises at least one magnetically transparent material (material that does not significantly attenuate a magnetic field passing through the material), preferably brass. Upon reading the teachings of this specification, those skilled in the art will now appreciate that, under appropriate circumstances, considering such issues as future technologies, cost, etc., other magnetically transparent materials, such as, for example, magnetically-transparent plastics, magnetically-transparent ceramics, other magnetically transparent metals, etc., may suffice.

Correspondingly, the lower magnetic roller assembly 450 preferably comprises at least one magnetizer array subassembly 520, preferably at least two magnetizer array subassemblies 520, as shown. The functional relationship between the two lower magnetizer array subassemblies 520 is representative of the functional relationship between the two upper magnetizer array subassemblies 510. For conciseness and clarity of description, the functional relationship between the two magnetizer array subassemblies 520 will be discussed with the understanding that the teachings are equally applicable to the functional relationship between the two upper magnetizer array

subassemblies 510.

Each magnetizer array subassembly 520 preferably comprises at least one leading magnetic roller 575 and preferably at least one trailing magnetic roller 570. Each upper magnetizer array subassembly 510 preferably comprises at least one leading magnetic bar 585 and preferably at least one trailing magnetic bar 580. Both magnetic roller assemblies 450 and magnetic bar assemblies 440 preferably extend across substantially the full width of feed path 430 and flexible magnetic sheet 141.

Leading magnetic roller 575 preferably comprises at least one rotational shaft 595 preferably oriented substantially perpendicular to the line of direction of feed path 430 (as generally defined by the direction of sheet motion), as shown. Leading magnetic roller 575 preferably comprises a first set of magnetic stacks 590, preferably spaced substantially along the length of rotational shaft 595, as shown. Each magnetic stack 590 preferably comprises an alternating sequence of magnetic plates and flux-conducting plates in a configuration preferably matching those of the previously-described magnetic stacks 239 shown and described in FIG. 8A and FIG. 8B. Each magnetic plate preferably comprises a high-strength permanent magnet and each flux-conducting plate preferably comprises a material exhibiting high permeability when saturated. Both magnetic plates and flux-conducting plates preferably comprise substantially circular peripheral shapes. Each substantially circular magnetic plate and each substantially circular flux-conducting plate are preferably substantially coaxial with rotational shaft 595, as shown. Thus, the sequential laminations of each magnetic stack 590 form a substantially cylindrical peripheral surface.

Magnetic stacks 590 are preferably mounted coaxially on rotational shaft 595, as shown. Magnetic stacks 590 are preferably separated by a set of spacers 592 that are also preferably mounted coaxially on rotational shaft 595, as shown. Spacers 592 preferably comprise widths generally slightly shorter than those of magnetic stacks 590, as shown. As in the prior magnetic stacks 239, magnetic stacks 590 preferably each comprise a 16-PPI stack 237, as shown in FIG 8A. Magnetic stacks 590 for high-energy magnetizer array assembly 405 preferably comprise a length of about 1- 1/8 inch. Spacers 592 preferably comprise a width of about 1 inch.

The preferred structures and arrangements of the upper leading magnetic bar 585 are substantially identical to those of the lower leading magnetic roller 575, as described above.

Preferably, the placements of magnetic stacks 465 along rotational shaft 595 of leading magnetic bar 585 are substantially identical to those of leading magnetic roller 575. This preferably places magnetic stacks 465 of leading magnetic bar 585 in vertical alignments with magnetic stacks 590 of leading magnetic roller 575. Thus, a plurality of first high-magnetic-flux field regions (six in the depicted embodiment) are preferably generated within the leading gap 645 (see FIG. 26) by the preferred vertical stacking of leading magnetic roller 575 below leading magnetic bar 585 and the resulting formation of magnetic flux circuits between leading magnetic roller 575 and leading magnetic bar 585.

The preferred structures and arrangements of trailing magnetic roller 570 are substantially similar to those of leading magnetic roller 575, with the exception of the preferred positioning of magnetic stacks 590 along rotational shaft 595, as shown. Note that magnetic stacks 590 of trailing magnetic roller 570 are preferably axially offset from magnetic stacks 590 of leading magnetic roller 575. More preferably, magnetic stacks 590 of trailing magnetic roller 570 are axially offset a preferred distance substantially equal to the width of one magnetic stack 590, as shown (similarly, magnetic stack 465 of the upper trailing magnetic bar 580 are axially offset from magnetic stack 465 of the upper leading magnetic bar 585), preferably centering magnetic stacks 590 of leading magnetic roller 575 on spacers 592 of trailing magnetic roller 570. This preferred arrangement produces a plurality of second high-magnetic-flux field regions (seven in the depicted embodiment) within trailing gap 640 (see FIG. 26), each of such second high-magnetic-flux field regions preferably generated by the preferred vertical stacking of trailing magnetic roller 570 below trailing magnetic bar 580. Note that the plurality of such second high-magnetic-flux field regions of trailing gap 640 are preferably axially offset from the plurality of such first high-magnetic-flux field regions of leading gap 645.

The preferred axial offsetting of the above-described magnetic stacks assures that the full width of flexible magnetic sheet 141 is exposed to at least one of the above-described high- magnetic-flux field regions as it is advanced along feed path 430, as shown. Thus, magnetization of flexible magnetic sheet 141 preferably occurs in parallel strips defined by alternating exposure to the magnetic fields of the leading and trailing magnetic rollers. The preferred axial offsetting of the depicted embodiment has been determined to reduce feed-related problems related to the adhering and wrapping of flexible magnetic sheet 141 around the magnetic rollers during operation. Upon reading the teachings of this specification, those of ordinary skill in the art will now understand that, under appropriate circumstances, considering such issues as intended use, physical characteristics of the flexible magnetic sheet, etc., other magnet arrangements, such as utilizing a continuous array of magnets extending substantially across the sheet width, etc., may suffice.

High-energy magnetizer array assembly 405 preferably comprises at least one magnetizer array plate 420. Magnetizer array plate 420 preferably mounts to lower portion 173 of briefcase enclosure 108, as shown, preferably with mounting fasteners 427 (see FIG. 20), preferably mounting screws. Upon reading the teachings of this specification, those skilled in the art will now appreciate that, under appropriate circumstances, considering such issues as future technologies, cost, etc., other mounting fasteners, such as, for example, bolts, snap-fit fasteners, twist-lock fasteners, etc., may suffice. Magnetizer array plate 420 preferably includes a set of rectangular-shaped apertures 530, preferably arranged in an offset configuration, as shown, corresponding to layout of magnetic stacks 590 of leading magnetic roller 575 and trailing magnetic roller 570. Rectangular-shaped apertures 530 preferably allow the magnetic stacks 590 of magnetic roller assembly 450 to project upwardly through magnetizer array plate 420 to contact flexible magnetic sheet 141, as shown in FIG. 21. In one preferred embodiment of the system, the trailing edge of each aperture 530 and opening preferably comprises an angled ramp 531, as diagrammatically shown in FIG. 21. Preferably, such angled ramps assists in maintaining smooth and consistent feed performance by reducing the tendency of flexible magnetic sheet to contact the trailing edge of the apertures due to magnetic adherence to the magnetizer banks. Preferably, each angled ramp comprises a tapered cut within the plate. More preferably, the angled ramps are formed by modifying a section of the plate to allow bending of the trailing edge of the aperture downward, as diagrammatically shown in FIG. 21.

The upper magnetic bar assembly 440 preferably mounts above magnetizer array plate 420, preferably outside lower portion 173 of briefcase enclosure 108. The lower magnetic roller assembly 450 preferably mounts below magnetizer array plate 420, preferably inside lower portion 173 of briefcase enclosure 108. At least one magnetizer array mounting fastener 505 preferably secures both the upper magnetic bar assembly 440 and the lower magnetic roller assembly 450, preferably by passing through magnetizer array plate 420, as shown. Magnetizer array mounting fastener 505 preferably comprises at least one bolt.

Each of the upper magnetizer array subassemblies 510 preferably further comprise at least one roller float spring 545, preferably at least two roller float springs 545. Roller float springs 545 preferably are positioned at each end of a respective magnetic bar, preferably inside outer casing 460. Roller float springs 545 preferably allow the series of magnetic stacks 465 to shift in a longitudinal direction, preferably to magnetically align with the lower magnetic stacks 590. In one preferred arrangement, outer casing 460 is preferably free to rotate in upper mounting bracket 540 and the internal magnetic bar is preferably free to longitudinally slide inside outer casing 460.

Preferably, leading magnetic bar 585 and trailing magnetic bar 580 are thereby free to translate in order to achieve optimal alignment with the upper and lower magnetic stacks, thus optimizing the high-magnetic-flux regions, as described herein. Upon reading the teachings of this specification, those skilled in the art will now appreciate that, under appropriate circumstances, considering such issues as cost, future technologies, etc., other mounting arrangements, such as, for example, vertically shifting outer casings, fine gap adjustments, etc., may suffice. Alternately preferably, each magnetic stack 465 of the upper magnetizer array subassemblies 510 are preferably separated by a roller float spring 545, as illustrated in FIG. 28. This alternate preferred arrangement permits each magnetic stack 465, of the upper magnetic bars, to align with a corresponding magnetic stack 590 of the adjacent of lower magnetizer array subassembly 520.

The lower magnetic roller assembly 450 preferably connects to motor 152 with at least one rotational drive subassembly 550.

This preferred mounting arrangement preferably places the resilient outer surface 703 of drive roller 702 in direct contact with one or more magnetic stacks 590 of the lower magnetic roller assembly 450, as shown. Preferably, rotation of leading magnetic roller 575 and trailing magnetic roller 570 is induced by the operation of motor 704 acting through chain drive 703 and drive roller 702.

In addition, alternate rotational drive subassembly 700 preferably comprises a set of rotatable magnet stay rollers 706, preferably configured to limit load deflections and maintain positioning of leading magnetic roller 575 and trailing magnetic roller 570 within magnetic roller assembly 450 during operation. Preferably, deflection within each magnetic roller is limited by the application of a force to the lower magnetic roller assembly 450 opposing the upward force applied to magnetic roller assembly 450. Magnet stay rollers 706 are preferably located adjacent each magnetic roller, preferably in front of leading magnetic roller 575 and behind trailing magnetic roller 570, as shown. Magnet stay rollers 706 preferably each comprise McMaster Carr Part number 2473K22 comprising a press-fit drive roller having about a 3/4-inch outer diameter and about a 3/4-inch width with a 1/4- inch inside bore diameter.
