Adaptive pressure media feeding
A tiltenator of a media separator module (integrated within a valuable media depository) adaptively controls pressure maintained against a bunch of media as individual items from the bunch are fed through the media separator module.
1 . A method for processing media items within a depository, the method comprising:
receiving, by a controller, a pressure reading from a pressure sensor associated with a tiltenator of a media separator module, wherein the tiltenator comprises a pressure plate configured to apply pressure to a bunch of media items;
adjusting, by the controller, a position of the pressure plate to apply an initial pressure to the bunch based on a type and a condition of the media items as determined from the pressure reading;
monitoring, by the controller, for a signal from a downstream sensor indicating whether a topmost item of the bunch has been separated and fed through the media separator module within a predetermined period of time;
modifying, by the controller, the pressure applied to the bunch by the pressure plate in response to an absence of the signal from the downstream sensor, wherein the modifying includes progressively and adaptively increasing the pressure in a series of incremental pressure adjustments; and
continuing the incremental pressure adjustments until the signal from the downstream sensor is received, indicating successful separation of the topmost item;
wherein the controller is further configured to reset a current pressure against the bunch to the initial pressure and back the topmost item and the bunch back to an entry feed point of the media separator module.
2 . The method of claim 1 , wherein the series of incremental adjustments are based on an ideal pressure for the type of media items and the condition.
3 . The method of claim 1 , wherein the controller is further configured to set the pressure back to a particular pressure that was present when the topmost item was first detected as being present by the downstream sensor.
4 . The method of claim 1 , wherein the controller is further configured to exit iteration of the series of incremental adjustments when a predetermined number of iterations is exhausted with no detection of the topmost item.
5 . The method of claim 1 , wherein the controller is further configured to increase an inter-item friction between the media items within the bunch by urging the pressure plate upward against a bottommost item.
6 . The method of claim 1 , wherein the controller is further configured to decrease a current pressure against the bunch as soon as the topmost item is detected as having reached the downstream sensor.
7 . A method for processing media items within a depository, the method comprising:
receiving, by a controller, a pressure reading from a pressure sensor associated with a tiltenator of a media separator module, wherein the tiltenator comprises a pressure plate configured to apply pressure to a bunch of media items;
adjusting, by the controller, a position of the pressure plate to apply an initial pressure to the bunch based on a type and a condition of the media items as determined from the pressure reading;
monitoring, by the controller, for a signal from a downstream sensor indicating whether a topmost item of the bunch has been separated and fed through the media separator module within a predetermined period of time;
modifying, by the controller, the pressure applied to the bunch by the pressure plate in response to an absence of the signal from the downstream sensor, wherein the modifying includes progressively and adaptively increasing the pressure in a series of incremental pressure adjustments; and
continuing the incremental pressure adjustments until the signal from the downstream sensor is received, indicating successful separation of the topmost item;
wherein the controller is further configured to back the topmost item and the bunch back to an entry point of the media separator module when a predefined number of incremental pressure increases are processed.
8 . The method of claim 7 , wherein the controller is further configured to progressively increment the pressure after a timeout period is reached in which the topmost item is not detected.
9 . The method of claim 7 , wherein the controller is further configured to iterate an incremental increase in pressure until the topmost item is detected by the downstream sensor.
10 . The method of claim 7 , wherein the controller is further configured to reset a current pressure for the tiltenator back to the initial pressure.
11 . A method comprising: A method for adaptive media item separation in a depository, the method comprising:
initiating, by a controller, a media separation process by engaging a tiltenator to apply a variable pressure to a bunch of media items, wherein the tiltenator includes a pressure plate and a pressure sensor;
determining, by the controller, an initial pressure against the bunch as a particular pressure for a predefined type of media and a predefined condition;
actuating, by the controller, the pressure plate to exert the initial pressure on the bunch to facilitate individual separation of media items from the bunch;
detecting, by the controller, when a topmost item from the bunch reaches a downstream sensor within a predetermined period of time; and
adjusting, by the controller, a corresponding pressure exerted by the pressure plate by progressively and adaptively increasing the corresponding pressure when the topmost item fails to reach the downstream sensor within the predetermined period of time;
wherein the controller is further configured to reset a current pressure against the bunch to the initial pressure and back the topmost item and the bunch back to an entry feed point.
12 . The method of claim 11 , wherein characteristics of the media items include the predefined type of media and the predefined condition for the predefined type of media.
13 . The method of claim 11 , wherein predetermined separation profile is based on an initial pressure against the bunch as a particular pressure for the predefined type of media and the predefined condition.
14 . The method of claim 11 , wherein the actuating of the pressure plate is performed to progressively achieve an increase in the corresponding pressure for the bunch.
15 . The method of claim 11 , further comprising decreasing the corresponding pressure while at least a portion of the topmost item remains partially within the bunch.
16 . The method of claim 11 , wherein the controller is further configured to set the corresponding pressure back to a particular pressure that was present when the topmost item was first detected.
