Method and system for storing flexible documents

A method (1) for storing a series of flexible documents ( . . . , B(n−1), B(n), B(n+1), . . . ) in a system (100), each flexible document ( . . . , B(n−1), B(n), B(n+1), . . . ) having a front side and a rear side and the system (100) comprising

• said method (1) comprising:
• A. activating using at least one sensor for sensing each flexible document ( . . . , B(n−1), B(n), B(n+1), . . . ) during transportation into a storing and issuing module (10) during storage operations, and providing corresponding dimension information and position information with respect to the longitudinal symmetry axis (y-y) to a central processing unit (50) or processor (150);
• and
• B. sensing a first flexible document B(n) by the at least one sensor inside the storing and issuing module (10), and
• C. sensing a next flexible document B(n+1) transported on a belt (20) toward the storing and issuing module (10) and determining corresponding position information for the next flexible document B(n+1) after the at least one sensor begins sensing a first flexible document B(n),
• D. based on dimension information and a last obtained position information on the flexible document B(n), dimension information and the last obtained position information on the next flexible document B(n+1), determining by the processor (50) a minimum distance (dpred), along an axis (yMIN−yMIN) parallel to a longitudinal symmetry axis (y-y), that would be left on transport tape (170), between the rear side of flexible document B(n) and the front side of the next flexible document B(n+1) of the series,
• E. comparing by processor (50) the determined minimum distance (dpred) with a predetermined minimum distance dd, and
• F. in response to the determined minimum distance (dpred) being different from the predetermined minimum distance dd, adjusting a linear speed (vt(t)) of the transport tape (170) between a time instant (tj(n)) at which flexible document B(n) is engaged with transport tape (170) and a time instant tj(n+1) at which the next flexible document B(n+1) is engaged with transport tape (170) inside the storing and issuing module (10).
