Definitions

  • the present invention is directed to devices and methods of detecting misfeeds in a document handling apparatus.
  • devices and methods utilizing only one detector and sonic processing to detect document jams.
  • Document scanners feed and transport paper documents past one or more imaging subsystems in order to create digital image files representative of the originals.
  • Systems have been described that detect excessive or unique sound energy using audio frequency microphones, the energy created by the document being transported when the document or documents are being damaged, wrinkled, torn or otherwise deformed by the feeding and transport process (referred to herein as a “misfeed”).
  • These sounds are differentiated from the normal sounds of the mechanisms via processing of the audio frequency sounds.
  • the sounds are quantified, compared to a threshold (which may be adjustable), and then used to immediately stop the feeding and/or transport mechanism in order to prevent or substantially limit damage to the documents.
  • Incorporating multiple devices for receiving audio information represents both a cost penalty and a packaging challenge given the position of drive rollers and other sensors within the document transport design.
  • This invention implements sound-based damage detection based on only one receiving device (in a preferred embodiment, an electret microphone), saving cost and enabling physical placement in paper transport systems where space may be at a premium.
  • the sound detection device (microphone) in a compliant mount or rubber isolator helps to reduce the conduction of unwanted sounds, noise, and vibrations into the microphone from the scanner mechanisms.
  • the electrical output amplitude of the sound detecting device may require additional amplification of the microphone output.
  • a preferred embodiment of the present invention comprises a sheet handling apparatus having a transport path, a device adapted to separate a first sheet from a plurality of stacked sheets and to feed the first sheet into the transport path, only one detector positioned near the transport path to detect a misfeed condition indicating that the first sheet is being damaged in the transport path, and a processing system coupled to the detector adapted to receive and process signals from the detector and configured to determine the misfeed in the transport path, and to terminate feeding sheets in response to the determination.
  • the detector comprises a microphone mounted into the apparatus using a compliant noise isolating material. An energy level of the digital audio data is calculated to determine the misfeed.
  • Another preferred embodiment of the present invention comprises an article processing apparatus having a transport path for the plurality of articles, a feeder device for feeding individual ones of the articles into the transport path, only one audio detector positioned in the transport path to detect a misfeed condition in the transport path, and a processing system coupled to the detector to process signals from the detector and configured to terminate processing in response to the signals from the detector.
  • An energy level of the signals from the detector is calculated to determine if the signals exceed an energy threshold, thereby indicating the misfeed condition.
  • a converter coupled to the detector converts the signals into digital data frames wherein the processing system counts a number of the data frames that indicate the misfeed condition.
  • a termination signal is issued if the number of data frames that exceed the energy threshold exceeds a preselected number.
  • Another preferred embodiment of the present invention comprises a method for feeding sheets by urging a sheet through a sheet transport path, providing only one audio receiver proximate the transport path, processing audio data detected by the audio receiver and terminating feeding sheets in response to determining a misfeed in the audio data, which includes calculating an energy level of the audio data.
  • the audio receiver is mounted proximate the transport path using a noise isolating compliant material.
  • Another preferred embodiment of the present invention comprises a method of determining a misfeed in an article processing apparatus by placing only one microphone in the article processing apparatus, feeding an article into the article processing apparatus, generating and collecting digital data frames of sound from the analog sound detected by the microphone, processing the collected data frames to determine the misfeed, including reducing a probability of a false misfeed determination by accumulating a number of data frames collected, and reducing a sensitivity setting if the number of data frames collected exceeds a threshold amount.
  • the number of data frames collected represents a distance that the document has traveled.
  • An energy level of the data frames is calculated and compared to a jam threshold for each data frame. The jam threshold is determined according to the sensitivity setting.
  • a jam count window is opened upon determining that the energy level of a current data frame exceeds its threshold.
  • the jam count window accumulates a jam count, which counts the number of data frames that exceed their threshold. If the jam count reaches a preselected jam count limit while the jam count window is open then a jam signal is issued.
  • the jam count window is closed if the total number of frames that have been processed exceeds a jam count window size and the jam count is reset to zero.
  • Another preferred embodiment of the present invention comprises a method of processing articles by holding a plurality of the articles to be processed in an input tray, feeding a first one of the articles into an article processing apparatus using a device configured to separate the first one of the articles from the plurality of the articles, collecting sound data using only one microphone, processing the sound data and determining if the sound data indicates a misfeed, and, if so, terminating processing the articles.
  • FIG. 1 illustrates a document feed and transport path.
  • FIGS. 2A-C illustrate frequency domain band pass filtering.
  • FIG. 3 illustrates a sonic processing circuit
  • FIG. 4 illustrates a pertinent frequency domain for detecting document damage.
  • FIG. 5 illustrates a flowchart of an algorithm for implementing the present invention.
  • FIG. 6 illustrates a timing diagram for processing document misfeeds.
  • FIG. 7 represents the first frame where the energy level exceeds the Energy_Threshold.
  • document 103 is moved forward by urging roller 101 into the feed and separation nip created by contact of rollers 105 .
  • a standard input tray holding a stack of documents wherein the urging roller is configured to separate the first one of the documents from the stack.
  • One document at a time is sequentially pushed further into the transport rollers 107 by selective rotation of the feed mechanism rollers 105 .
  • the document is transported to an imaging station or stations to be converted into a digital image. Sound energy created by the physical transport of the document through the transport is also converted to an electrical signal by receiver 111 .
  • This sound energy may be characteristic of normal, undamaged transport of the document including that of the scanner itself, or may contain sounds characteristic of a document undergoing damage as a result of the feed and/or transport process.
  • the electrical signal from microphone 111 is representative of the sounds associated with document transport. This signal is conveyed to amplifiers and signal conditioning block 115 which is described later.
  • the electrical signal from microphone 211 is representative of all sounds received, including the lower frequency sounds associated with document transport including, potentially, those associated with document damage.
  • This composite signal is conveyed to amplifiers and signal conditioning block 215 and is illustrated in the frequency domain in FIG. 2A .
  • the signal conditioning electronics separates the relatively low frequency signals associated with document transport, including the sounds of potential damage, using the bandpass filter in FIG. 2B that allows frequencies between the lower limit of F 1 and the upper limit of F 2 in the range of approximately 100 Hz to 10 KHz, respectively, to pass through while greatly attenuating the higher frequency sounds.
  • the output of this filter is shown in FIG. 2C .
  • the output of the bandpass filter illustrated by FIGS. 2B and 2C is passed to an analog-to-digital converter, which receives analog audio data and converts these to digital data frames as described below.
  • the output of microphone 311 is amplified and filtered in the frequency domain.
  • the output of amplifier and filter block 305 contains signals primarily associated with document transport, including those associated with possible damage as it is transported. These signals are converted to a digital representation by analog-to-digital converter 309 and then to the document damage processor 313 which makes a determination if the sound signals represent those of a document being damaged or not.
  • Processor 313 receives signal 315 from the scanner controller when the feed mechanism is engaged. This prepares the damage detection processor 313 and initiates the detection algorithm which will be described later. If sounds associated with document damage are detected with sufficient energy and within timing windows as described below, then an output 317 from processor 313 is sent to the scanner controller which in turn quickly stops the transport and feed mechanisms to limit the damage to the document in question.
  • the damage detection processor determines when document damage due to misfeeding, wrinkles, staples, adhesion or other factors is occurring and stops the document transport motors and feed mechanisms in a very brief time interval to prevent further damage to the documents.
  • the document damage detection algorithm uses the idea of differentiating between the sound made by a normal document entering a document scanner and the sound of a document being wrinkled due to a jam. For a system to make this distinction, it is important to ignore or in some way isolate the background sounds of the scanner from the sounds coming from the document.
  • the background sounds come from various moving parts of the scanner.
  • the moving parts include, but are not limited to, the transport motors, transport rollers, feeder mechanism and possible cooling fans. These scanner background sounds are typically periodic and have low frequency components relative to that of documents being damaged.
  • the sounds from a wrinkling or damaging document are a short duration signal in the time domain and have frequency components spread over a wide range in the frequency domain.
  • the sound of a clean document being scanned typically has frequencies that overlap the frequencies that of a wrinkling document. Therefore, the algorithm can detect a jamming document by computing the energy of the audio signal by looking at a frequency band between F 5 and F 6 as shown in FIG. 4 , where F 5 is the upper frequency limit of the background noise/clean document in the range of approximately 1 KHz. and where F 6 is the upper frequency of a jamming document in the range of approximately 4 KHz.
  • the cut-off frequency F 5 is selected such that all the background sounds from different moving parts of the scanner and the sound associated with a clean document are substantially or detectably below this cut-off as shown below. This cut-off frequency selection can be based on test data collected and recorded from the scanners during normal operation.
  • the damage detection processor uses a communicated feed enable signal generated at this point to determine when to start sampling the microphone.
  • the algorithm for jam detection uses a frame-based processing technique. The system collects the digitized microphone data and processes the data in fixed data sets or frames that consist of N samples per frame 502 , for example, typically approximately 50 samples. The algorithm receives multiple frames of microphone data and then will determine if the data is indicative of a document jam as will be described below. These frames of data are non-overlapping and each frame consists of approximately a one millisecond duration of audio data.
  • the trail edge of the document may make a snapping sound that creates a sharp impulse in the audio signal.
  • an additional check 503 needs to be performed to determine where the microphone frame was captured in relation to the lead-edge of the document. This is done by keeping track of how many frames have been processed since the feeder mechanism enable signal was asserted, and if the current frame number has passed the Sensitivity Switch Point (SSP).
  • SSP Sensitivity Switch Point
  • the trail edge will pass by the point of feeding sooner for short documents and is therefore the limiting case for the need to switch to a lower sensitivity and avoid false jam detections.
  • the number of frames counted to cross the SSP is equivalent to the time to transport the shortest document such that the trail edge passes over the point of feeding.
  • the Sensitivity Switch Point 505 If the frame count is greater than the Sensitivity Switch Point 505 , then the current frame for the microphone is susceptible to this trailing edge false detection and the low sensitivity settings are used 507 in a later stage for determining whether or not a document jam has occurred. If the frame count has not passed the SSP 509 , then the high sensitivity settings will be used 511 .
  • Each frame of microphone output data is next processed by sending the digitized data through a band pass filter 513 with lower and upper cutoff frequencies F 5 and F 6 as previously described in FIG. 4 .
  • a 1D median filter 515 is next applied to the frame of data to help distinguish audio characteristics between a document that is merely wrinkled which exhibits intermittent high peak values, as opposed to a document in the process of being damaged which has relatively continuous high values of amplitude.
  • the median filter, energy threshold calculations, and Jam Count window accumulation all combine to distinguish merely wrinkled documents from those being damaged during transport.
  • the energy of the microphone frame of data is calculated 517 .
  • the energy of the frame of data is calculated with the equation below, where N represents the number of data samples within a frame, and mic data is a number correlated to a sound intensity of each individual digitized audio sample.
  • the algorithm completely ignores these frames of data by forcing the energy level to zero 521 .
  • An example number of ignored frames is about thirty. This prevents the algorithm from falsely detecting the feeder mechanism noise as a potential jam.
  • the energy calculation from 517 is compared against a sensitivity threshold 523 that is varied depending on whether we are in the low or high sensitivity mode as determined previously in 503 .
  • a potential wrinkling document is detected when the energy level of the frame goes above the Energy_Threshold 524 . When this occurs, the algorithm initiates a jam count window if one has not been previously initiated and increments the Jam Count variable 525 .
  • This window defines a block of frames where the energy level of some minimum number of frames must exceed the Energy_Threshold before an actual jam detection signal is issued. If the Jam Count exceeds the JamCount_Threshold 527 , then the jam signal is asserted 529 and the algorithm terminates 541 . Otherwise, if the Jam Count is below the JamCount_Threshold 543 , then the algorithm waits for next frame of data.
  • the algorithm increments the current position within the jam count window, assuming a jam had occurred on an earlier frame (jam count >0) and a jam count window was open 535 .
  • Jam # 1 represents the first frame where the energy level exceeds the Energy_Threshold and the jam count window opens. As each future frame is processed, the current position within the window is updated.
  • Jam Detect #N represents the frame where the Jam Count exceeds the JamCount_Threshold before the window closes.
  • this timing diagram represents a single document traveling through the scanner.
  • the damage detection algorithm commences when the feed mechanism enable signal is passed 601 from the main scanner controller to the damage detection processor.
  • the delay period 603 is utilized to avoid false jam detection due to the sounds associated with the feed mechanism and a document entering the paper transport.
  • the algorithm starts to actively look for sound signal data associated with document damage.
  • the initial portion of the document is processed at high sensitivity in region 607 until there is the risk of false damage detection due to the trail edge of the document.
  • the sensitivity drops to the lower sensitivity for the remainder of this document 611 until the end of the document is reached 613 and the algorithm terminates until the next document is fed.
