Media handing devices that process multiple document bunches must separate the documents for individual processing downstream within the media handling devices. A media separator is a component of the media handling devices. Typically, the media separator uses an ultrasonic sensor for detecting any overlapping documents.
The ultrasonic sensor reports when a detection is made as to whether the ultrasonic sensor detects: i) a clear condition, ii) a single condition, or iii) a double condition. A clear condition indicates that no document is detected by the ultrasonic sensor. A single condition indicates that one document is detected by the ultrasonic sensor. A double condition indicates one or multiple documents are detected by the ultrasonic sensor. Additionally, in situations where overlapping documents cover half of the ultrasonic sensor while the other half of the ultrasonic sensor is clear, the ultrasonic sensor will report a single condition.
A double feed recovery is performed by the media separator to separate any detected overlapping documents within the media separator. However, performance of the double feed recovery reduces throughput of document processing within the media handling device.
For purposes of maintaining adequate document processing throughput within the media handling device, the double feed recovery processing is not instantly performed when the ultrasonic sensor reports a double condition; this allows for a certain amount of time to give the documents a chance to properly separate within the media separator. However, if the double condition remains after the elapsed period of time, the double feed recover is performed. But, if the ultrasonic sensors report a single or clear condition before the elapsed period of time, the documents are assumed to have properly separated from one another and double feed recovery is not performed and document throughput within the media handling device is maintained.
One significant issue with double feed recovery is that folded documents can fool the double feed recovery processing, such that a document may appear as being successfully separated but in reality a fold in the document has passed the ultrasonic sensor. The folded documents can jam downstream processing within the media handling device and result in manual service calls to remedy the jam, and during such time until the jam is resolved the media handling device is out of service.
In various embodiments, methods and a system for folded media detection and processing within a valuable media depository are provided.
According to an embodiment, a method for folded media detection and processing is presented. Specifically, and in one embodiment, a folded media condition is detected within a media separator module for an item of media. Next, a determination is made as to whether to eject the item from the media separator module and whether to perform double feed recovery processing on the item within the media separator module based on the detected folded media condition.
The depository 100 is suitable for use within an Automated Teller Machine (ATM), which can be utilized to process deposited banknotes and checks (valuable media as a mixed bunch if desired). The deposit module 100 has an access mouth 101 (media or document infeed) through which incoming checks and/or banknotes are deposited or outgoing checks and/or banknotes are dispensed. This mouth 101 is aligned with an infeed aperture in the fascia of the ATM in which the depository 100 is located, which thus provides an input/output slot to the customer. A bunch (stack) of one or more items (valuable media) is input or output. Incoming checks and/or banknotes follow a first transport path 102 away from the mouth 101 in a substantially horizontal direction from right to left shown in the
Items are then directed substantially vertically downwards to a point between two nip rollers 108. These nip rollers cooperate and are rotated in opposite directions with respect to each other to either draw deposited checks and/or banknotes inwards (and urge those checks and/or banknotes towards the right hand side in the

During conventional document separation processing, a conventional separator module would detect one of three conditions reported from the conventional ultrasonic sensors. A clear condition indicating that there is no document detected between the ultrasonic sensors; a single condition indicating that a single document is detected between the ultrasonic sensors; and double condition indicating one or multiple documents are detected between the ultrasonic sensors. The conventional separator module pauses for a small configured amount of time when the double condition is detected and after such pause takes another reading from the ultrasonic sensors to see if the double condition has resolved itself. When the double condition is not resolved, the conventional separator module performs a double feed recovery attempt to separate the potential multiple documents within the separator module through selective activation of the conventional transport drives. After a configured amount of unsuccessful attempts to automatically separate the multiple documents, the conventional separator module ejects the documents from the conventional separator module. Thus, the conventional separator module has three modes of operation: a normal mode (where no dual document processing is needed), a dual recovery mode (where dual documents are detected and separation processing is performed, and an ejection mode (where documents after having attempted the dual recovery processing fail to separate and the documents are ejected back out an entry point in the conventional separator module).
As will be discussed more completely herein and below, the media separator module 103 is configured to detect a variety of different types of folds for a single document being processed within the media separator module 103 and further configured to perform double feed recovery processing and/or ejection processing on the document based on the different types of detected folds for the single document. This provides for folded document detection and optimal and timely document throughput processing of documents through the media separator module 103. Moreover, in some situations, one or more transport drives (103C1, 103C2, 103D1, and/or 103D2) are activated in a manner that is different from that which has been done conventionally for document double feed recovery and document ejection in response to the detected folded document detection; thereby, providing a novel fourth mode of operation for the media separator module 103.
A variety of folded document detection conditions and media separator module 103 processing is now discussed with reference to the
Tail Edge Document Fold Detection and Processing
As a document 103E is urged through the media separator module 103, the ultrasonic sensors 103A and 1038 provide readings for the document. The start of the document 103E is noted through ultrasonic sensor readings and readings are reported as the document travels through the media separator module 103. The ultrasonic sensors 103A and 103B report conditions for the document 103E as the document 103E is being processed through the media separator module 103 at different selective locations.
The ultrasonic sensors 103A and 13B provide readings that indicate one of three conditions for the document 103A passing between the sensors 103A and 103B: a clear condition, a blockage with a single condition (single document sensed), and a blockage with a double condition (potentially a single document with a type of fold or potential two documents that have not been properly separated).
When, the ultrasonic sensors 103A and 103B report readings from the ultrasonic sensors 103A and 13B near an end of the document 103E having a double condition, a controller for the media separator module 103 is configured to stop the transport drives (103C1, 103C2, 103D1, and 103D2). The time lag between the controller issuing the instruction to the mechanical componentry of the transport drives (103C1, 103C2, 103D1, and 103D2) to stop or halt and when the transport drives (103C1, 103C2, 103D1, and 103D2) actually mechanically stop or halt results in the document 103E traveling a small additional distance along the document's direction of travel through the media separator module 103. Two situations with respect to the document can thusly be noted.
The first condition represents a state or reading from the ultrasonic sensors 103A and 103B after the transport drives (103C1, 103C2, 103D1, and 103D2) actually stop after having been issued an instruction to stop by the controller of the media separator module 103 following a tail edge document fold being detected.
The first condition depicted in the
The second condition represents a state or reading from the ultrasonic sensors 103A and 1038 after the transport drives (103C1, 103C2, 103D1, and 103D2) actually stop after having been issued an instruction to stop by the controller of the media separator module 103 following a tail edge document fold being detected.
The second condition depicted in the
If the second condition turns out to be a document 103E that is legitimately folded, the controller will exhaust a configured number of processing iterations of double feed recovery with no change in the ultrasonic sensor readings and a double feed failure is reported and the folded document 103E will not be fed any further downstream within the media separator 103. When the second condition is truly overlapping documents, double feed recovery processing will separate the overlapping documents and the separated documents will feed properly through the media separator module 103.
Lead Edge Document Fold
Here, as the initial presence of the document 103E is detected between the ultrasonic sensors 103A and 1038 the readings indicate to the controller that the document 103E was sensed with a double condition and the controller issues a halt command to the transport drives (103C1, 103C2, 103D1, and 103D2). This sensed double condition associated with the document 103E is an indication to the controller of a lead edge document fold condition or state within the media separator module 103. Again, the time between the controller issuing the stop or halt to the transport drives (103C1, 103C2, 103D1, and 103D2) and when the transport drives (103C1, 103C2, 103D1, and 103D2) actually stop results in the document 103E traveling a small distance between the ultrasonic sensors 103A and 1038, such that the reading from the ultrasonic sensors 103A and 1038 when the transport drives (103C1, 103C2, 103D1, and 103D2) have completed halted or stopped can present two additional conditions or states for the media separator module 103.
The reading obtained when the transport drives (103C1, 103C2, 103D1, and 103D2) have completely stopped indicates a double condition, which indicates a first condition that document has: a large lead edge document fold, a mid-body fold, or two overlapping documents that have not been properly separated within the separator module 103. Therefore, the controller performs double feed recovery processing within the media separator module 103. When the first condition is truly overlapping documents, double feed recovery processing will separate the overlapping documents and the separated documents will feed properly through the media separator module 103. After the configured number of processing iterations of the double feed recovery is performed with still no change in the readings from the ultrasonic sensors 103A and 103B, the controller reports double feed failure and the document 103E will not be fed further downstream within the media separator module 103.
The reading obtained when the transport drives (103C1, 103C2, 103D1, and 103D2) have completely stopped indicates a single condition, which indicates a second condition that document has: a small lead edge document fold, a mid-body fold, or two overlapping documents that have not been properly separated within the separator module 103. Therefore, the controller performs double feed recovery processing within the media separator module 103. When the second condition is truly overlapping documents, double feed recovery processing will separate the overlapping documents and the separated documents will feed properly through the media separator module 103. After the configured number of processing iterations of the double feed recovery is performed with still no change in the readings from the ultrasonic sensors 103A and 103B, the controller reports double feed failure and the document 103E will not be fed further downstream within the media separator module 103.
Mid-Body Document Fold
When the ultrasonic sensors 103A and 103B report readings after the start of the document 103E and before the end of the document 103E indicating a double condition, this situation indicates to the controller of the media separator module a mid-body document fold appearing in the document. The controller upon receiving the reading issues a stop instruction to the transport drives (103C1, 103C2, 103D1, and 103D2). A second reading from the transport drives (103C1, 103C2, 103D1, and 103D2) is obtained from the controller indicating two different conditions once the transport drives (103C1, 103C2, 103D1, and 103D2) have actually stopped or halted.
If the second reading following a mid-body document fold reading from the transport drives (103C1, 103C2, 103D1, and 103D2) after actually stopping still indicates a double condition, then the controller determines that the first condition following the mid-body document fold is a condition where the document has: a large lead edge fold, a mid-body fold, or potentially two overlapping and unseparated documents. The controller performs double feed recover, resulting in documents being properly separated or a double feed recover error (as discussed above).
If the second reading following a mid-body document fold reading from the transport drives (103C1, 103C2, 103D1, and 103D2) after actually stopping still indicates a single condition, then the controller determines that the second condition following the mid-body document fold is a condition where the document has: a small lead edge fold, a small mid-body fold, or potentially two overlapping and unseparated documents. The controller performs double feed recover, resulting in documents being properly separated or a double feed recover error (as discussed above).
New Mode of Operation for Single Document Condition
In any of the above-mentioned situations when the second reading following a controller-issued halt or stop instruction to the transport drives (103C1, 103C2, 103D1, and 103D2) indicates a document 103E having a single condition, the controller can operate the media separator module 103 in a new and novel mode of operation (an added fourth mode to the above three-mentioned conventional modes for a conventional separator module).
In the new mode of operation, the controller determines that the second reading indicates: a single document 103E with a tail edge document fold sitting half way over the ultrasonic sensors 103A and 1038, a document 103E with a mid-body document fold that has now gone past the ultrasonic sensors 103A and 1038, or overlapping and unseparated documents.
In response to this, the controller instructs the transport drives (103C1, 103C2, 103D1, and 103D2) to move forward a small and configured distance and an additional third reading is taken from the ultrasonic sensors 103A and 1038. This is not conventionally done and is a new mode of operation for the media separator module 103.
If the third reading indicates a clear condition (no document 103E detected between the ultrasonic sensors 103A and 1038 with the third reading), then the controller determines that this is a document 103E with a tail edge fold. In this situation, no further double feed recovery processing is needed at all, which minimizes further damage to the document 103E and maximizes the likelihood of the document 103E being successfully ejected from the media separator module 103.
If the third reading indicates a single or double condition, then the controller determines that this is a document 103E with a fold (large tail fold, mid-body, or lead-edge fold) and the fold has now gone further past the ultrasonic sensors 103A and 1038; a single document with multiple folds; or overlapping and unseparated documents. Here, the controller performs double feed recovery processing. If the document is really folded, double feed recovery will exhaust its retires and report double feed recovery error but the folded document 103E will not be fed for any further document 103E processing downstream within the media separator module 103. Again, if unseparated documents were detected, the documents will be separated during the double feed recovery processing and fed successfully through the media separator module 103.
As is now apparent, the configuration and processing of the media separator module 103 improves conventional media separator modules by: i) reducing fatal faults within a depository 100; ii) reducing service calls by minimizing document 103E feed retries within the media separator module 103E on folded documents and ejects folded documents before those folded documents can be fed downstream within the depository 100 to downstream document 103E processing modules; and iii) improving/enhancing processing throughput of documents through the media separator module 103 and the valuable media depository 100.
