In a first cycle of operation, all but the lowermost bag is raised away from the base, the raised bags defining a depleted stack of bags. Then, while the depleted stack remains raised, the lowermost bag is removed from the chamber through a chamber outlet opening. Then, the depleted stack is lowered to seat a new lowermost bag on the base to complete first cycle. The cycle is repeated for each lowermost bag. Each bag removed from the magazine chamber may be conveyed to a bag pick-up position located away from the magazine assembly and, from there, automatically picked with a carrying tool located at the end of a robotic arm and transported to a bag filling station for filling with the flowable material. In the case of valve bags, the valve may be opened by the carrying tool at the time of pick-up.

Depending on a type of media (paper, cotton, polymer notes, cash, checks, etc.) and the condition of the media (new, worn, folded, crumpled, etc.) being inserted into the separator, the friction between the items of media in the bunch can vary greatly. Similarly, if the items of media are folded, curled, sprayed, skewed, etc., the feeding pressure may not be ideal for the separator. For example, if brand new checks are inserted, the inter-item friction in the bunch is much higher than between worn paper/cotton currency notes.When the feed pressure for the bunch being fed into the media separator is ...

The control portion detects a position of a trailing end of a preceding sheet separated by the separating portion by using the second detecting sensor, and detects presence or absence of a subsequent sheet placed on the tray by using the first detecting sensor. Based on detection results of the first detecting sensor and second detecting sensor, the control portion controls the driving source such that the feeding roller starts to feed the subsequent sheet.
