Embodiment Construction

[0027] Referring now more specifically to the drawings, and in particular to FIG. 1 , there is shown a roller assembly 10 comprising a static charge neutralization device 12 of the present invention operatively mounted on a roller 14 for dissipating the static charge on the roller 14. electrostatic charge buildup on the In the exemplary embodiment shown, the rollers 14 are transport rollers, but other roller types are possible for other purposes.

[0028] Roller 14 includes a hollow tubular casing 16 mounted for rotation on an axis of rotation 18 . The tube case 16 includes both ends 20 and 22 mounted with bearings or the like on a rotary shaft 18 completely passing through the tube case 16 . The ends 24 and 26 of the rotating shaft 18 protrude beyond the roller ends 20 and 22, thereby providing a structure in which the roller 14 can be operatively mounted in an apparatus or machine.

[0029] The static neutralization device 12 is housed in the envelope 16 and includes a mou...

Abstract

A static charge neutralization device for moving parts of equipment includes a plurality of filaments on a conductive carrier tape, the ends of the filaments being disposed adjacent to, but spaced apart from, the moving parts. These filaments will induce ionization in the presence of an electric field generated by the electrostatically charged surface of the moving part.

Description

technical field [0001] The present invention relates to static charge neutralization devices for rollers and rotating shafts, and more particularly, the present invention relates to non-contact static charge neutralization devices. Background technique [0002] It is known to use non-conductive bearings and bushings in conveyor rollers and other rollers in various processing equipment in order to provide a non-corrosive arrangement and reduce equipment cost. For good durability and corrosion resistance, a known type of non-conductive bearing is made of nylon, polyurethane or other composites. These non-metallic bearings do not require grease or other lubricants and are therefore often preferred for machinery used in food processing equipment, medical material production equipment, and other equipment that requires protection from contamination. [0003] One disadvantage of using such non-conductive bearings on rollers and shafts is the generation and storage of static charg...
