Abstract
The present invention relates to a feed device for feeding a sorting machine for sorting flat objects and comprising at least one input feeder for the objects and pockets to which the objects are fed vertically for transport, the feed device allowing the objects to be fed one by one from the input feeder towards a vertical pocket. A conveyor module comprises at least two stop gates spaced by a distance greater than the maximum length of the objects. An accelerator module is located between the conveyor module and a vertical transfer device and comprises a downstream stop gate. The vertical ejection device is formed by an injecting module. These modules are provided with continuously operating positive entrainment devices and the stop gates control the movements of the objects in response to detectors located in the path of the objects.
