1. A device for sorting out individual articles in the form of sheets deviating from the main quantity of a consecutive feedout, said device comprising:
- a first pair of cooperating rollers (5,
6),a second pair of cooperating rollers (3,
4),a third pair of cooperating rollers (1,
2),a first set of conveyor belts (11),a second set of conveyor belts (12),a stationary member (13),and a collecting box (9), the axes of the rollers in said first pair of cooperating rollers being disposed in a plane at right angles to a feed-in-plane for said articles through a nip formed between said rollers,the axes of the rollers in said second pair of rollers being disposed in a plane forming an acute angle to a plane disposed at right angles to the feed-in plane,the axes of the rollers in said third pair of cooperating rollers being diposed in a plane lying at right angles to a feedout plane for said articles through a nip formed between said rollers,said first set of conveyor belts passing around one roller in each of said second and third pairs of rollers,said second set of conveyor belts passing around a second roller in said second and third pairs of rollers,motor means drivably coupled to said first and second pairs of rollers with said first and second belts running partially in approximately a common plane,sensing means (8) controllably connected to said motor means and operatively disposed to sense articles conveyed between said first and second sets of conveyor belts in said common plane,said stationary member being located lower than said first pair of rollers and being shaped such that articles conveyed into the nip of said first pair of rollers and into the nip of said second pair of rollers for being passed between said sensing means will pass over said stationary member, whereas if said sensing means reject the relevant article and concurrently reverse the motor said article will be rejected by the direction of motion of the first and second sets of belts being reversed, thereby releasing the article for passing the latter below said stationary member, andsaid reversed articles being collected in said collecting box.

Abstract
A device for sorting out individual articles which differ from the main quantity in a consecutive feedout. Articles to be conveyed in response to specific conditions, for example monetary bills which are to be discharged individually and which are to face the same direction, are supplied to a nip between a pair of rollers, with the axes of said rollers being disposed in a plane forming an acute angle to the path of conveyance through the rollers. The articles are sensed individually after passing said rollers, and if the specific condition is not fulfilled the direction of rotation of the rollers is reversed, whereby the differing articles (bills) are returned towards the place where they originally entered the nip but are conveyed down below a shield which they have passed over in their previous conveyance. The rejected articles are collected after having passed below the shield.
