A device for conveying flat objects in series and edge-on, in which the flat objects ( ) are moved in a conveying direction (D), while at the same time being separated each from the next by a spacing which is normally constant, has a synchronization system ( ) capable of compensating for any variations in spacing between two consecutive objects. The system includes two parallel rows ( ) of driven wheels ( A- C) made of elastically deformable elastomer and between which each object is gripped and moved in the conveying direction. Each wheel has a rotation spindle ( ), the position of which is fixed, and the wheels are rotated by a motorization system which is controlled to accelerate and/or retard the movement of each object between the two rows of wheels on the basis of a detection whether the front edge of the object has been early or late in passing a determined position upstream of the two rows of wheels compared with a time reference indicating the spacing between objects. The device may be used in a postal sorting machine operating in a synchronous mode.

Device for conveying flat objects with a synchronization system

A device ( ) for removing flat objects from a stack includes a magazine ( ), in which flat objects are stacked on edge to be serialized, and a vertical destacking plate ( ) disposed directly in front of the magazine ( ) and against which the first object (O ) of the stack is pressed. The first object (O ) of the stack is ejected in a direction (E) perpendicular to the direction of advance (D) of the stack of flat objects in the magazine ( ). The device ( ) also includes means ( ) for measuring the thickness of each flat object pressed against the destacking plate ( ). This thickness measurement serves as a feedback control for the movement of the stack of flat objects in the magazine ( ). The device ( ) may be used in a postal sorting machine.

The device for individually transferring flat objects from an entry conveyor ( ) on which the objects travel in series edge-on in a first direction (A), into buckets ( ) of an exit conveyor ( ), comprises an intermediate conveyor ( ) arranged in the continuation of the entry conveyor above the exit conveyor and equipped with receptacles ( ) 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. It further comprises an injection system ( ) comprising elastically deformable wheels ( ) 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 conveyor.
