Description




FIELD OF THE INVENTION




The present invention relates to media handling devices and media handling methods.




BACKGROUND OF THE INVENTION




Image forming devices, such as printers and copiers, have become increasingly sophisticated. Some image forming devices provide additional functions other than typical printing or document reproduction functions. Some conventional printers and other image formation systems include a plurality of device attachments or stations configured to handle such additional functions. More specifically, in addition to the provided image formation equipment, assemblies can be included for stapling documents, stacking documents, folding documents, etc.




Media handling devices are typically provided to direct media to proper document preparation stations. In some applications, handling functions of media are implemented to provide proper orientation or presentation of media to the various document preparation stations. An exemplary handling function is flipping the orientation of media during passage of the media from one station to another.




Accordingly, conventional paper handling systems have been developed to provide flipping and other media handling functions. One exemplary media handling device includes an input device configured to receive media and initially direct media within the media handling device. A set of rollers is typically positioned downstream of such input device. During entry of media within the media handling device, the rollers are provided in a receiving state wherein the rollers are separated by a fixed distance in order to receive the incoming media. Following entry of the media intermediate the separated rollers, a motor is actuated to draw one roller towards the other roller with the inputted media therebetween.




The movement of the roller is implemented using a direct current (DC) motor in some designs. In such arrangements, the DC motor operates to move the separated roller towards the other roller to contact the media. Thereafter, the plural rollers control subsequent movement of the media within the media handling device.




In conventional configurations, the DC motor drives the movable roller to a hard stop against the other roller. Such is implemented without the use of feedback control to indicate the position of the roller being moved. However, the hard stops have been observed to produce acoustic noise during operation of the media handling device. Such acoustic noise is undesirable in many environments.




Therefore, a need exists to provide improved media handling devices and methodologies to handle the movement of media.




SUMMARY OF THE INVENTION




According to one aspect of the invention, a media handling device comprises: a housing having an initial media path; a moveable guide member positioned to guide media within the initial media path; a motor configured to selectively move the guide member intermediate a first position where the guide member is spaced from the media within the initial media path and a second position where the guide member contacts the media within the initial media path; and a controller configured to apply a control signal to the motor to control the motor and corresponding movement of the guide member, the controller being further configured to modulate the control signal.




A second aspect of the invention provides a media handling device comprising: a housing having a first media path and a second media path; an input configured to provide media into the first media path; an output configured to output media from the second media path; a moveable guide member configured to direct the media from the first media path to the second media path to flip the media; a motor configured to move the guide member intermediate a first position where the guide member is spaced from the media within the initial media path and a second position where the guide member contacts the media within the initial media path; and a controller configured to apply a control signal to the motor to control the motor and corresponding movement of the guide member, the controller being further configured to modulate the control signal.




Another aspect of the invention provides a media handling method comprising: providing a media handling device having an initial media path; selectively moving a guide member using a motor intermediate a first position where the guide member is spaced from media within the initial media path and a second position where the guide member contacts the media within the initial media path; applying a control signal to the motor to control the moving; and modulating the control signal.

24


(shown in phantom) responsive to rotation of guide members


36


,


38


. Media

can comprise paper, envelopes, transparencies, etc. The depicted media


50


comprises a sheet of paper having edges


52


,


54


. During travel along media path


24


, edge


52


is a leading edge and edge


54


is a trailing edge.





FIG. 3

illustrates the initial movement of media


50


within media handling device


14

through input


20


and over sensor


34


. Guide member


40


is provided in the first or initial position as shown during reception of media


50


within media handling device


14


.




Referring to

, guide member


40


is illustrated being lowered towards guide


42


. Responsive to detection of leading edge


52


by sensor


34


, a motor (shown in

FIG. 8

) is controlled to lower guide member


40


towards the second position adjacent guide member


42


. The rotational speed of guides


36


,


38


can be increased following detection of media


50


by sensor


34


.




Referring to

FIG. 5

, guide member


40


is illustrated in the second position (position


41


of

FIG. 2

) adjacent guide member


42


. Guide assembly


30


defines a nip


56


to receive media


50


during positioning of moveable guide member


40


in position


41


. Following the passage of edge


54


of media


50


out of guide assembly


28


, flap


48


may be driven by a motor (not shown) in a downward direction towards media


50


. Although not shown, a sensor may be provided on a downstream side of guide assembly


28


to monitor the exit of edge


54


from guide assembly


28


.




Referring to

FIG. 6

, such downward movement of flap


48


guides media


50


to media path


26


and guide assembly


32


. Following the appropriate positioning of media


50


using flap


48


, the direction of rotation of guide member


42


is reversed to direct media


50


towards guide assembly


32


. The direction of rotation of guide member


42


is reversed after a sufficient stabilization period of time following the reception of media


50


along media path


24


within nip


56


. Guide member


42


directs media


50


into a nip


58


defined by guide members


44


,


46


of guide assembly


32


.




Referring to

FIG. 7

, guide members


44


,


46


are driven to pass media


50


along media path


26


towards output


22


. Media


50


is passed to media device


16


(

FIG. 1

) following passage through output


22


. The direction of media


50


from input


20


along media paths


24


,


26


to output


22


flips the orientation of media


50


.




Following passage of media to guide assembly


32


, guide member


40


is raised towards the initial position of guide member


40


shown in FIG.


3


. Additionally, flap


48


is raised along with guide member


40


to a position for receiving subsequent media along media path


24


.




Referring to

FIG. 8

, a controller


60


and a motor


62


are illustrated. In particular, controller


60


is coupled with sensor


34


and motor


62


. Motor


62


is additionally coupled with guide member


40


. In the depicted configuration, controller


60


comprises a microcontroller configured to execute firmware for controlling the operations of media handling device


14


. In the depicted configuration, motor


62


comprises a direct current (DC) motor. Motor


62


is driven by current controlled responsive to a control signal received from controller


60


.




As described further below, operations of controller


60


are provided for controlling guide member


40


using motor


62


. More specifically, controller


60


receives position information of media


50


from sensor


34


. Responsive to such position information, controller


60


can regulate motor


62


to control the movement of moveable guide member


40


intermediate the first position and the second position.




It is desired to reduce the acoustic noise of media handling device


14


during the movement of guide member


40


intermediate such first and second positions. Accordingly, controller


60


is configured to apply a control signal as described below to motor


62


to control the operation thereof and corresponding movement of guide member


40


.




In accordance with certain aspects of the invention, controller


60


is configured to modulate the control signal applied to motor


62


. As described further below, controller


60


is configured in one embodiment to selectively pulse width modulate the control signal applied to motor


62


. Controller


60


is configured to modulate the control signal during movement of guide member


40


in the described embodiment. At other times, controller


60


provides a substantially constant or steady state control signal to motor


62


.




In one embodiment, the application of the substantially constant control signal to motor


62


is responsive to guide member


40


being in one of the first position and the second position. Controller


60


is configured to detect a hard stop of moveable guide member


40


at one of the first position and the second position. Controller


60


then provides the constant control signal to motor


62


after detection of the hard stop.




Motor


62


applies a holding torque to guide member


40


responsive to reception of the constant control signal. Such is utilized to increase a normal force within nip


56


of guide assembly


30


to assist with the movement of media


50


during the positioning of guide member


40


in the second position. Additionally, if the modulated control signal fails to fully move guide member


40


to one of the first position or the second position, the subsequent constant control signal can urge or fully move guide member


40


to the appropriate first position or second position.




According to another aspect, controller


60


is configured to time the modulation of the control signal and to provide the substantially constant control signal after timing a predefined length of time. Such length of time is typically chosen to be of sufficient duration for guide member


40


to fully travel the distance intermediate the first position and the second position. Other control schemes utilizing a modulated control signal to control motor


62


are possible.




Different modulation schemes were utilized in experiments to tune the control of motor


62


. Table A below illustrates exemplary modulation schemes and corresponding operations of media handling device


14


.

Following experimentation, controller


60


is configured in one aspect to provide the following operation for controlling motor


62


. During movement of guide member


40


in a downward direction from the first position to the second position, controller


60


is configured to use a 25% duty cycle (5 ms timing) for approximately 150 ms. Following the timing of the predefined length of time (e.g., 150 ms), controller


60


applies a constant control signal to motor


62


to provide full current within motor


62


for application of the holding torque (increased normal force applied to media) during movement of media


50


out of guide assembly


30


to media path


26


. Such constant control signal also assures movement of guide member


40


into the second position.




Following the passage of media


50


to guide assembly


32


, guide member


40


is returned to the first position. During upwards movement from the second position to the first position of moveable guide member


40


, the control signal is modulated by controller


60


using a 50% duty cycle for approximately 150 ms. Following the timing of 150 ms, 100 ms of a constant control signal is applied to motor


62


to implement full current operation thereof. Such is utilized in one aspect to assure proper return of guide member


40


into the first position.




Referring to

FIG. 9

, a flow chart illustrates an exemplary method for controller


60


to control the movement of guide member


40


from the first position to the second position and vice versa. The method is implemented as executable code within the firmware of media handling device


14


according to one aspect. Alternatively, such methodology can be implemented within hardware in another configuration.




For movement of guide member


40


from the first position to the second position, controller


60


determines at step S


10


whether an initiate event has occurred. An exemplary initiate event is the detection of media within media handling device


14


. Sensor


34


is utilized to indicate such presence of media in the described embodiment. Controller


60


idles at step S


10


until media is detected.




Thereafter, controller


60


proceeds to step S


12


following the detection of the initiate event. At step S


12


, controller


60


issues or outputs a modulated control signal to motor


62


. The control signal may be modulated according to one of the exemplary schemes described above.




Controller


60


then proceeds to step S


14


to determine whether an intermediate event has been detected. In one aspect, controller


60


is configured to time a predefined time period comprising the intermediate event. Step S


14


is utilized in such a configuration to apply the modulated control signal to motor


62


for the predefined time period. The intermediate event comprises a hard stop detection of guide member


40


in the second position according to another aspect. Controller


60


proceeds to step S


16


responsive to the detection of an intermediate event.




At step S


16


, controller


60


outputs the constant control signal to motor


62


. Application of the constant control signal results in the application of a holding torque of guide member


40


to media


50


and guide member


42


.




Thereafter, controller


60


proceeds to step S


18


to monitor for the presence of a termination event. During application of the constant control signal with guide member


40


in the second position, an appropriate detection event can be an indication from a sensor that the media has been moved from guide assembly


30


. Another exemplary termination event is a timer (e.g., controller


60


) counting a predefined time period.




Following detection of the termination event with guide member


40


in the second position, controller


60


proceeds to step S


20


to de-assert the constant control signal to idle motor


62


.




Thereafter, controller


60


can re-execute the depicted method of the flow chart of

FIG. 9

to control the movement of guide member


40


from the second position back to the first position. The following describes execution of the depicted flow chart during movement of guide member


40


from the second position to the first position.




Controller


60


determines at step S


10


whether an initiate event has occurred. The initiate event is the passage of media from guide assembly


30


to guide assembly


32


according to one aspect. Controller


60


idles at step S


10


until the initiate event is detected.




Thereafter, controller


60


proceeds to step S


12


following the detection of the initiate event. At step S


12


, controller


60


issues or outputs a modulated control signal to motor


62


. The control signal may be modulated according to one of the exemplary schemes described above for providing upward movement of guide member


40


to return to the first position.




Controller


60


then proceeds to step S


14


to determine whether an intermediate event has been detected. In one aspect, controller


60


is configured to time a predefined time period comprising the intermediate event. Step S


14


is utilized in such a configuration to provide the application of the modulated control signal to motor


62


for the predefined time period. The intermediate event comprises a hard stop detection of guide member


40


in the first position according to another aspect. Controller


60


then proceeds to step S


16


responsive to the detection of an intermediate event.




At step S


16


, controller


60


outputs the constant control signal to motor


62


. The constant control signal can operate to kick or urge guide member


40


fully into the desired first position.




Thereafter, controller


60


proceeds to step S


18


to monitor for the presence of a termination event. During application of the constant control signal with guide member


40


in the first position, an exemplary termination event is the timing of a predefined period of time (e.g., 100 ms). Other termination events are possible.




Following detection of the termination event with guide member


40


in the first position, controller


60


proceeds to step S


20


to de-assert the constant control signal to idle motor


62


.




Thereafter, controller


60


returns to step S


10


in one configuration to await the detection of another initiate event (e.g., reception of new media) and to execute the depicted flow chart methodology again to provide movement of guide member


40


from the first position to the second position. The depicted flow chart is repeated during operation of media handling device


14


to continuously flip media.




Referring to

FIG. 10

, a timing diagram illustrates various operations of media handling device


14


. Time increases from left to right in the depicted timing diagram. Plural lines are illustrated in FIG.


10


. Line


70


illustrates the movement of motor


62


during the operation of media handling device


14


. Line


72


illustrates current within motor


62


during such operations. Line


74


illustrates an enable control signal issued by controller


60


to control the current within motor


62


. Line


76


illustrates a direction control signal of controller


62


to control motor


62


to control the direction of movement of guide member


40


intermediate the first and second positions. Guide member


40


is moved downward responsive to control signal


76


being asserted. Guide member


40


is moved upward responsive to control signal


76


being de-asserted.




The timing diagram is illustrated initially with guide member


40


in the first position. At time t


0


, an initiate event is detected by controller


60


of media handling device


14


. Such results in the application of a modulated control signal from controller


60


to motor


62


as represented by line


74


. At time t


1


, an intermediate event is detected (e.g., a predefined length of time has been timed) and the modulated control signal of line


74


is de-asserted.




Thereafter, application of a constant control signal as shown by line


74


provides a full current holding torque of motor


62


applied in a downward direction to urge guide member


40


fully to the second position.




At time t


2


, a termination event occurs (e.g., media has left guide assembly


30


for travel along the second media path


26


). In the described configuration, controller


60


thereafter re-executes the method of the flow chart and operates to again output a modulated control signal corresponding to line


74


to move guide member


40


upward towards the first position. The reader will note that signal


76


is de-asserted at time t


2


to provide upward movement to guide member


40


.




The modulated control signal represented by line


74


is outputted for a predefined length of time. Following the timing of the predefined length of time at time t


3


, a constant control signal is issued again by controller


60


as represented by line


74


to urge guide member


40


into the first position. Controller


60


times the application of the second constant control signal as represented by line


74
