Abstract

Proposed is the addition of spring loaded rollers to magnetic skis employed on a vertical transport in a High Capacity Feeder (HFC). Currently there is a drive problem associated with the movement of copy sheets along the vertical transport and around a turn baffle on the HFC. The principle of moving copy sheets on the transport depends upon a frictional difference between the copy sheet and transport belt material and a frictional difference between the copy sheet and ski material. A magnet located behind the ski material provides a normal force to move the copy sheet on the transport. In a present system, frictional differences may vary due to a wide range of copy sheet sizes, weights, and smoothness commonly in use today. Consequently so, the drive force will also vary. These variations will further cause differences in the timing of copy sheets moving along the transport and around the turn area.

MAGNETIC ROLLER SKI, (Cont'd)

Proposed is the addition of spring loaded rollers to magnetic skis employed on a vertical transport in a High Capacity Feeder (HFC).

Currently there is a drive problem associated with the movement of copy sheets along the vertical transport and around a turn baffle on the HFC. The principle of moving copy sheets on the transport depends upon a frictional difference between the copy sheet and transport belt material and a frictional difference between the copy sheet and ski material. A magnet located behind the ski material provides a normal force to move the copy sheet on the transport. In a present system, frictional differences may vary due to a wide range of copy sheet sizes, weights, and smoothness commonly in use today. Consequently so, the drive force will also vary. These variations will further cause differences in the timing of copy sheets moving along the transport and around the turn area.

Drive system efficiency is improved when friction between the copy sheet and ski material is reduced so as to not affect the drive force. By reworking the magnetic skis and adding spring loaded rollers, the normal forces can be redistributed to provide the same force with reduced drag. Reduced drag increases the total net drive for...
