TAKE-OFF SYSTEM FOR HANDLING LETTERS AND THE LIKE

摘要

The invention relates to a take-off system for taking off letters and the like, comprising a first take-off device (1) into which the letters are supplied in an upright position on a transport bed (2), from where they can be conveyed one by one to a reversing station (3) for reversing the direction of movement, and further comprising an outlet (5) for separating letters with a non-acceptable length from the stream. The reversing station (3) is formed by the combination of a stacker (3 min ) and a second take-off device (3 sec ), the moment when a next letter is taken off being determined by the signal from a photodetector (26) concerning the passage of the letters taken off by said second take-off device, and by the information from a measuring point (20) with regard to the lengths of the letters which are supplied to the stacker (3 min ). The measuring point (20) and the photodetector (26) are connected to a processor (22), which puts the second take-off device into operation for a short moment at calculated points of time.
