Device for transferring flat objects with an injector comprising elastically deformable wheels

A device for individually transferring flat objects (9, 9A) from an entry conveyor (2) on which said objects travel in series edge-on in a first direction (A), into buckets (6) of an exit conveyor (5), the device comprising an intermediate conveyor (7) arranged in the continuation of the entry conveyor above the exit conveyor and equipped with receptacles (8) which, over at least part of their path, can move in a second direction (B) perpendicular to said first direction, each flat object leaving the entry conveyor being injected edge-on into a receptacle of the intermediate conveyor which comes up to face the exit of the entry conveyor so as to be transferred edge-on into a bucket of the exit conveyor, wherein an injection system (14) is disposed at the exit end of the entry conveyor and designed to accelerate and then retard the movement of each flat object in said first direction before injecting it into a receptacle of the intermediate conveyors, said injection system comprising two parallel rows of several elastically deformable elastomer wheels (15) with stationary rotation spindles, between which wheels each flat object is gripped, these two rows of wheels comprising wheels (15A, 15B) arranged on the same side as the entry conveyor and rotated at constant speed with the possibility of being placed freely at overspeed and wheels (15C) arranged on the same side as the intermediate conveyor, which are rotated at variable at variable speed.
