Double pick separator device comprising means for retaining a flat object which might otherwise be entrained by friction by another flat object being moved in a predetermined transfer direction by transfer means. The retaining means are mounted on a structure mobile in a direction substantially perpendicular to the transfer direction. The separator device further comprises means for exerting a holding force on the retaining means, said holding force being oriented in a holding direction substantially perpendicular to the transfer direction. Application to automatic mail sorting, especially to sorting mail items of varying thickness.

Double pick separator device and flat object unstacking device equipped

An automatic mail sorting flat object holding device has a driven perforated belt and suction grasping heads inside the belt. The holding device has a holding side consisting of the perforated belt moving in a predetermined transfer direction and to the front of which a stack of flat objects is offered up. A double pick separator has a suction head disposed substantially facing an exit edge of the holding side. The suction holding device has at least two substantially adjacent suction heads aligned in the transfer direction, one suction head of which is at least partly overlapping the double pick separator suction head.

Flat object holding device and flat object unstacking device equipped

A flat object transfer device for transferring flat objects, particularly flat objects of varying thickness, to a sorting device from the output of an unstacking device. The flat object transfer device includes a gripping device for gripping a flat object initially located in a transfer plane. The gripping device includes a set of pinch rollers and pulleywheels on opposite sides of each pinch roller. A set of drive belts are trained around each pinch roller and the pulleywheels on opposite sides of the pinch roller. At least one of the pinch rollers in the set of pinch rollers can move in a direction substantially perpendicular to the transfer plane. A double pick separator device is provided for retaining flat objects except for a flat object to be gripped by the gripping device. The double pick separator device is disposed between two levels of the drive belts trained around the pinch rollers and pulleywheels. The gripping device can be controlled by a control device so as to immobilize the flat object pending authorization for its transfer to the sorting device.

Flat object transfer device, and unstacking device equipped with this

The present invention concerns a device for feeding a stack of flat articles on edge, especially mail items, to a de-stacker head provided with a support surface, the device comprising a main feed magazine in which the stack is disposed and a plate pushing the rear of the stack. A secondary feed magazine is introduced between the main magazine and the support surface of the de-stacker head, the secondary magazine having an upwardly inclined transfer surface, its edge adjacent to the support surface of the de-stacker head being higher than the latter.
