Description

[Brief explanation of the drawing]

The drawing shows paper sheet feeding by the paper sheet counting machine according to the present invention.

FIG. 2 is a side view of FIG. 1. 1 is the hopper bottom plate, 2 is the feed roller shaft, 3゜4 is the first feed roller, 5 is the first friction surface, 6 is the smooth surface, 7 is the second feed roller, 8 is a partial clutch, 9 is the second friction 10.11 is the separation roller, 12 is the paper receiving plate, 13 is the first
Guide plate, 13a is a flat section, 14 is a second guide plate, 15 is a sheet detector, 18. . 19 is a pull-out roller, 20 is a spindle, 21 is a lever, 22
is a pinch roller, and 23 is a spring. Correction 1982. 3.22 The scope of claims for utility model registration shall be amended as follows. ■Scope of Claim for Utility Model Registration In a device configured to separate paper sheets one by one in a hopper and accumulate them in a feeding stacker, a part of the circumferential surface becomes a first friction surface with a large frictional force. a feed-out roller shaft in which first feed-out openings/-ra of the go pair are spaced apart from each other in the axial direction, and the remaining circumferential surface of the cage is a smooth surface with a friction force smaller than that of the first friction surface; A second friction surface that is installed between the first feeding rollers on the feeding roller shaft and is made of a material that has approximately the same frictional force as the first friction surface over the entire circumferential surface.
a partial clutch provided coaxially between the feeding roller shaft and the second feeding roller and configured to be free in the sheet feeding direction and locked in the opposite direction; and a pair of pull-out rollers disposed on the sheet-feeding side of the feed-out roller, and while the fed-out sheet is in contact with the smooth surface of the first feed-out roller, the circumferential speed of the first feed-out roller is increased. A sheet feeding device for a sheet counting machine, characterized in that the sheet is drawn out by each pull-out roller at a constant speed not subject to any restrictions.

Claims (1)

[Scope of utility model registration request] In a hopper configured to separate paper sheets one by one and stack them on a feeding stacker, a part of the circumferential surface is a first friction surface with a large frictional force, and the remaining circumferential surface is a first friction surface with a large frictional force. A feed-out roller shaft in which a pair of first feed-out rollers having a smooth surface with a frictional force smaller than that of the first friction surface are spaced apart from each other in the axial direction, and a surface of the first feed-out roller on the feed-out roller shaft. A second friction surface that is attached to the second friction surface and is made of a material that has approximately the same frictional force as the first friction surface over the entire circumference of five surfaces.
a partial clutch provided coaxially between the feeding roller shaft and the second feeding roller and configured to be free in the sheet feeding direction and locked in the opposite direction; and a pair of pull-out rollers disposed on the sheet-feeding side of the feed-out roller, and while the fed-out sheet is in contact with the smooth surface of the first feed-out roller, the circumferential speed of the first feed-out roller is increased. C) A sheet feeding device for a sheet counting machine, characterized in that the sheet is drawn out at a constant speed by each pull-out roller.
