Embodiments described herein relate generally to an information display technique in an decoloring apparatus that decolors a color of an image formed with an decolorable colorant.
In the past, an decoloring apparatus has been known that applies heating processing to a sheet, on which an image is formed with a so-called decolorable colorant, to decolor a color of the image on the sheet and makes the sheet reusable.
An decoloring apparatus has also been known that determines whether various sheets to be subjected to decoloring processing are decolorable and determines whether the decoloring processing is successful.
In the decoloring processing in the decoloring apparatus, in some case, the decoloring processing cannot be executed or cannot be sufficiently performed because there is a tear or a bend in a sheet to be subjected to the decoloring processing or a stapled bundle of sheets is directly set.
When a viewpoint of a reduction in an environmental load is taken into account, it is important to grasp information concerning a processing state of the decoloring processing in the decoloring apparatus. However, in a user interface screen in the past, it is difficult to grasp such information.
In general, according to one embodiment, a decoloring apparatus includes a sheet conveying unit, a decolorinq unit, a reading unit, a controlling unit, a storing unit and a display control unit. The sheet conveying unit conveys the sheet. The decoloring unit decolors a color of the image formed with a decolorable colorant on the sheet conveyed by the sheet conveying unit. The reading unit reads a sheet conveyed by the sheet conveying unit and acquires an image. The controlling unit determines whether or not the sheet is reusable based on the image which the reading unit acquired. The storing unit stores a first number of sheets which the controlling unit determines whether or not they are reusable, a second number of sheets determined to be reusable, and a third number of sheets determined not to be reusable. The display control unit causes a display unit to display the information indicating at least one of the second number, the third number and the reuse ratio of the second number of sheets to the first number of sheets.
Embodiments are explained below with reference to the accompanying drawings.
First Embodiment
First, a first embodiment is explained.
The decoloring apparatus E subjects a sheet on which an image is formed with an “decolorable colorant” such as a so-called decolorable toner or decolorable ink to “decoloring processing” for decoloring a color of the decolorable colorant.
As shown in
The display unit 805a can include, for example, an electronic paper, an LCD (Liquid Crystal Display), an EL (Electronic Luminescence), a PDP (Plasma Display Panel), or a CRT (Cathode Ray Tube).
The display unit 805a and the touch panel-type operation unit 805b cooperate with each other, whereby a so-called touch panel display is realized.
In the decoloring apparatus E according to this embodiment, the processor 801 has a role of performing various kinds of processing in the decoloring apparatus E. The processor 801 also has a role of realizing various functions by executing computer programs stored in the memory 803, the HDD 804, and the like. It goes without saying that the processor 801 can also be realized by a CPU (Central Processing Unit) or an MPU (Micro Processing Unit) that can execute equivalent arithmetic processing. Similarly, the HDD 804 can be replaced with a storage device such as a flash memory.
The memory 803 can include, for example, a RAM (Random Access Memory), a ROM (Read Only Memory), a DRAM (Dynamic Random Access Memory), an SRAM (Static Random Access Memory), a VRAM (Video RAM), or a flash memory. The memory 803 has a role of storing various kinds of information and computer programs used in the decoloring apparatus E.
The IC card reader 807 reads ID information of a user from an IC card carried by the user. The processor 801 performs personal authentication processing on the basis of the ID information read by the IC card reader 807.
The processor 801 and the ASIC 802 can perform information transmission and reception with external apparatuses such as a network server and an image forming apparatus (MFP: Multi Function Peripheral) through, for example, a LAN line.
An internal configuration of the decoloring apparatus E is explained in detail below.
The decoloring apparatus E includes, for example, the feeding cassettes 505 and 506 configured to stack and store sheets having images formed thereon to be subjected to decoloring processing, the discharge cassettes 501 and 502 configured to store the sheets subjected to the decoloring processing in the decoloring apparatus E, the reject box 509 (equivalent to a disposal sheet storing unit) configured to store un-reusable sheets, a lever-type thickness sensor 507 configured to detect the thickness of a conveyed sheet, double feed sensors 508 configured to detect double feed of sheets fed from the feeding cassettes 505 and 506, an optical line sensor 504 for detecting a printing state (including luminance, soil, stain, crease, and color) of the image formed on a surface of the conveyed sheet, decoloring processing units 503a and 503b configured to heat and decolor the image formed with an decolorable colorant on the sheet, conveying paths Pa to Pj and the like for leading a conveyance target sheet in a predetermined sheet conveying direction, conveying rollers R3 to R8 configured to convey the sheet through the conveying paths Pa to Pj and the like, sheet feeding rollers R1 and R2 configured to feed the sheets from the feeding cassettes 505 and 506 to the conveying paths, discharge rollers R9 and R10 configured to discharge sheets subjected to the decoloring processing to the discharge cassettes 501 and 502, and flappers F provided at branch points of the conveying paths.
The conveying paths Pa to Pj and the like and the conveying rollers R3 to R8 and the like are equivalent to a “sheet conveying unit”. The conveying rollers R1 to R10 are controlled to be driven by the processor 801. A conveying direction of a sheet conveyed by the sheet conveying unit is regulated by the flappers F controlled by the processor 801.
The sheet conveying unit includes the conveying paths Pc, Pd, and Pe serving as a “disposal sheet conveying path” for conveying a sheet passed through the line sensor 504 (an image reading unit) in the sheet conveying direction to the reject box 509 configured to store un-reusable sheets.
The line sensor 504 and the processor 801 cooperate with each other to realize a function of the “image reading unit”.
The line sensor 504 is arranged further on the upstream side in the sheet conveying direction than the decoloring processing units 503a and 503b and scans an image formed on the sheet conveyed by the sheet conveying unit. The processor 801 detects, on the basis of image data read from the sheet by the line sensor 504, a printing ratio, printing density, a printing color (equivalent to printing state information), and the like of the image formed on the sheet.
The line sensor 504 can read, concerning both sides of the sheet, the printing ratio, the printing density, the printing color, and the like as the “printing state information”.
The thickness sensor 507 and the processor 801 cooperate with each other to realize a function of a “sheet-thickness detecting unit”. The thickness sensor 507 is arranged further on the upstream side than the decoloring processing units 503a and 503b in the sheet conveying direction by the sheet conveying unit. The thickness sensor 507 includes a lever member 507L that can rotate with a rotating shaft 507r as a fulcrum. The lever member 507L is urged by an elastic member such as a spring in a counterclockwise direction in
The processor 801 is equivalent to a “processing control unit”.
The decoloring processing unit 503a includes rollers a1 and a2 and a belt a3 wound and suspended around the rollers. The belt a3 also rotates according to rotation of the rollers. At least one of the rollers al and a2 is driven to rotate by the processor 801. At least one of the rollers a1 and a2 is heated by a heater controlled by the processor 801.
Similarly, the decoloring processing unit 503b includes rollers b1 and b2 and a belt b3 wound and suspended around the rollers. The belt b3 also rotates according to rotation of the rollers. At least one of the rollers b1 and b2 is driven to rotate by the processor 801. At least one of the rollers b1 and b2 is heated by the heater controlled by the processor 801.
The decoloring processing units 503a and 503b having the configuration explained above heat a sheet nipped and conveyed by the belts a3 and b3, the conveying rollers R6 and R7, and the like while conveying the sheet to thereby decolor an image of an decolorable colorant formed on the sheet.
The processor 801 (the processing control unit) controls control parameters for the decoloring processing by the decoloring processing units 503a and 503b, sheet conveying speed by the sheet conveying unit, and the like on the basis of the acquired printing state information.
Further, the processor 801 conveys the sheet subjected to the decoloring processing to the line sensor 504 through the conveying path Pj and the conveying path Pg to thereby cause the line sensor 504 to read images on both sides of the sheet subjected to the decoloring processing.
A basic operation of processing in the decoloring apparatus E according to the first embodiment is explained below.
The processor 801 controls the sheet feeding roller R1 or R2 to feed a sheet Sb to be subjected to the decoloring processing from the cassette 505 or 506 to the sheet conveying path.
The double feed sensors 508 perform double feed detection of sheets fed from the cassettes 505 and 506.
If double feed is detected by any of the double feed sensors 508, the processor 801 drives the conveying roller R3 or R4 to discharge the sheets, the double feed of which is detected, to the reject box 509 through the conveying path Pc or Pd.
Subsequently, the processor 801 acquires information by detecting, using the thickness sensor 507, the thickness of one sheet fed without being doubly fed.
If the sheet thickness detected by the thickness sensor 507 exceeds a predetermined threshold, the processor 801 discharges the sheet to the reject box 509 through the conveying paths Pb, Ph, and Pe.
The conveying path Pb is provided further on the upstream side than the line sensor 504 in the sheet conveying direction. This makes it possible to prevent a sheet having thickness exceeding a tolerance in the line sensor 504 from entering the line sensor 504. Therefore, it is possible to prevent occurrence of deficiencies such as a sheet jam and breakage in the line sensor 504.
If sheets are not doubly fed and the sheet thickness does not exceed the predetermined threshold, the processor 801 causes the line sensor 504 to read images on both sides of the sheet.
The processor 801 controls the conveying rollers R6, R7, R5, and the like to discharge a sheet having a “printing ratio” or “printing density”, which is detected based on the images read by the line sensor 504, exceeding a predetermined threshold to the reject box 509 through the conveying paths Pi, Pj, and Pe.
The processor 801 (the processing control unit) controls, on the basis of information acquired from the line sensor 504, the thickness sensor 507, and the like, control parameters of the decoloring processing performed by the decoloring processing units 503a and 503b and the sheet conveying unit in cooperation with each other.
The processor 801 executes, on the basis of the control parameters set to correspond to a sheet to be subjected to the decoloring processing as explained above, the decoloring processing performed by the conveying rollers R6 and R7, the decoloring processing units 503a and 503b, and the like in cooperation with one another on the sheet.
The processor 801 conveys the sheet subjected to the decoloring processing to the line sensor 504 through the conveying paths Pj and Pg to thereby read images on both sides of the sheet subjected to the decoloring processing.
As a result of the image reading, if it is determined that a color of a colorant remains on the sheet at density equal to or larger than a predetermined value, the processor 801 determines how many times the decoloring processing is already repeated for the sheet. If the decoloring processing is repeated the number of times equal to or larger than a predefined number of times, the processor 801 determines that it is difficult to decolor the colorant and causes the sheet conveying unit to discharge the sheet to the reject box 509 through the conveying paths Pi, Pj, and Pe. History information concerning how many times the decoloring processing is applied to a certain sheet can be stored in, for example, the memory 803 or the HDD 804.
On the other hand, if the decoloring processing is not repeated the number of times equal to or larger than the predefined number of times, the processor 801 executes the decoloring processing again.
The processor 801 reads the images on both the sides of the sheet subjected to the decoloring processing with the line sensor 504. If it is determined that the colorant having density equal to or larger than the predetermined value does not remain on the sheet, the processor 801 causes the sheet conveying unit to discharge the sheet to the discharge cassette 501 or 502 through the conveying paths Pi, Pj, and Pf.
The processor 801 and the ASIC 802 accumulate logs of various kinds of processing performed in the decoloring apparatus E in the HDD 804 as a data table. Further, in order to perform dynamic display processing involved in the execution of the decoloring processing, the processor 801 and the ASIC 802 perform processing for data addition to the data table on a real time basis every time data that should be added is generated. The processor 801 and the ASIC 802 always refer to the dynamically-updated data table to thereby dynamically update display contents (e.g., data contents of the data table) on the display unit 805a.
First, the processor 801 and the ASIC 802 register information of items (1) to (6) below in association with an decoloring processing ID issued for each kind of decoloring processing when the decoloring processing is performed in the decoloring apparatus E (see
Further, the processor 801 and the ASIC 802 register information of items (7) to (10) below in association with the decoloring processing ID issued for each kind of decoloring processing when the decoloring processing is performed in the decoloring apparatus E (see
Moreover, the processor 801 and the ASIC 802 register each of predetermined periods and information of items (11) to (13) below concerning processing contents of respective kinds of decoloring processing executed in the periods in association with each other when the decoloring processing is performed in the decoloring apparatus E (see
The processor 801 and the ASIC 802 can sort or process each data of the data table, which is stored in the HDD 804, in a desired array or arrangement order and use the data. For example, the processor 801 and the ASIC 802 can generate the data of (7) to (13) by processing or totalizing the data of (1) to (6).

If the sheet set as the detection target is a “sheet on which the decoloring processing in the decoloring processing units cannot be executed”, the decolorability determining unit 101 determines, on the basis of the detection result in at least one of the line sensor 504 and the thickness sensor 507, to which of plural predetermined results a reason for unexecutability of the decoloring processing corresponds.
