A device for unstacking flat objects comprises an unstacking head (2) provided with a suction cup (88) for grasping the first flat object in a stack of such objects presented thereto and for moving a grasped flat object towards an exit position (40) in which the object is released. The suction cup (88) is a bellows suction cup made of a flexible material such that when it grasps the first flat object in the stack, it retracts under the effect of the suction and entrains at least the surface of the grasped object therewith as it retracts. A shoe (90) having a surface close to the grasping plane of the suction cup is disposed adjacent to the suction cup in fixed relationship relative to the mount (50) carrying the suction cup. The shoe thus constitutes an obstacle to the surface of a grasped flat object, thereby warping said surface as the suction cup retracts.

Device for unstacking flat objects

The magazine has slats for advancing flat articles to an unstacking head. The magazine comprises a first zone into which articles are loaded and along which they are advanced by removable slats, which slats are individually mounted in the first zone, being held and guided therein and also being driven therealong. The magazine also includes a second zone for stocking slats that are not in use, with the second zone being formed adjacent to the unstacking terminal portion of the first zone and being equipped for removing the slats form the first zone, and for transferring the removed slats into a stock of slats. The invention is applicable to separating postal items one by one.

Magazine for storing and feeding flat articles to be unstacked

A method of extracting and accelerating flat objects such as postal items which are presented in the outlet position of an unstacking head for use by a machine downstream therefrom, the method making use of a clamp for grasping postal items one-by-one and of various sensors (7) such as photoelectric cells, serving to indicate the presence of a postal item in the outlet position of the unstacking head, or in the field of action of the clamp, or serving to indicate that the clamp is in a waiting position or in an end-of-stroke position, the method being characterized in that it essentially comprises the following stages:
