[Embodiment 1] Next, the control of the toner removing apparatus shown in FIG. 1 will be described with reference to the flowcharts shown in FIGS. FIG. 3 is a flow chart of control of the toner removing device having the above-described configuration, and FIG. 4 is a sub-flowchart showing the toner removing processing mode of the same flowchart. First, referring to FIG. 3, as described above, the resistors 914a, b,
When a current flows through 915 to start heating of the rollers 302 and 402, and the temperature of each of the rollers 302 and 402 reaches a temperature (setting value of RAM) sufficient for peeling or drying, the control unit 920. Via the operation display unit 50
Indicates that the operation is possible (LED lighting, etc.). When the operation command data is transmitted from the control unit 920 of the operation display unit 50, the CPU 904 operates the main drive motor 922, and when the load of the motor can be driven at a constant speed, the paper feed motor 923 is driven to feed the paper. Start (step 1).
The transferred transfer paper 10 is read by the transfer paper state sensor 105 with data for determining whether or not it can be reused (step 2). This data is converted into parallel digital data by the A / D converter 918, and if necessary, image processing is executed to judge the transfer paper state (step 3). (Hereafter, margin)

Next, the registration motor 924 rotates while timing with the paper feed motor 923 to prevent skew (step 4). Next, the transfer paper state data is compared with the contents (the image area ratio limit value, the reuse limit value, etc.) written in the ROM 905, and it is determined whether the toner removal processing is possible (step 5). ). If it is determined that the toner removal processing is impossible, the paper feed mode is entered (step 6), the deflecting claw solenoid 932 is driven, and the transfer paper 10 is ejected to the paper ejection tray 501b (step 7). On the other hand, when it is determined that the toner removal processing is possible, the toner removal processing mode described later is executed (step 8).

In the toner removal processing mode (see FIG. 4), the registration motor 924 sends the transfer paper 10 to the position of the open clamp claw 602 of the paper holding drum 601. When control data for closing the clamp claw 602 of the paper holding drum 601 is sent to the parallel interface 908, the driver 910 operates the solenoid 926 to close the clamp claw 602 and grip the transfer paper 10 (step 8- 1a), the paper holding drum motor 933 is turned on and rotated (step 8-2a).

Next, a predetermined initial rotation speed R ₀ is initially set as the rotation speed R of the coating rollers 207a, 207b (step 8-3a). This rotation speed R is set in the RAM 919. Here, the initial setting value of the rotation speed R of the coating rollers 207a, 207a may be changed based on the state data of the transfer sheet 10 read by the transfer sheet state sensor 105.

Then, the coating rollers 207a, 207b are rotated at the rotational speed R (R ₀ ) which is initially set in the RAM 919, and the transfer rollers 10 on the paper holding drum 601 are interfaced with the transfer rollers 207a, 207b. The above penetration promoting liquid 21 such as an activator and the treatment liquid 20 such as distilled water are applied (step 8-4a). As a result, the treatment liquid 20 permeates into the interface between the transfer paper 10 and the toner.

Next, the transfer paper 10 and the toner entangled therein are easily peeled off by heating with the heating lamp 30, and the toner is peeled off from the transfer paper 10 by the peeling roller 302 (step 8). -5a).

After the peeling process is performed, the CCD
The sensor 603 detects the unremoved toner image remaining on the transfer paper 10 (step 8-6a). Here, the detection data by the CCD sensor 603 is the A / D converter 91.
It is sent to the CPU 904 via 8 and it is judged whether or not the ratio of the remaining image area of the unremoved image is equal to or less than the predetermined value a% (step 8-7a). In the case of NO, it is further determined whether or not the liquid applying process and the peeling process have been performed b times or more (step 8-8a). If NO in step 8-8a, a value obtained by adding a predetermined rotation speed r to the rotation speed R of the coating rollers 207a and 207a set in the RAM 919 up to then is newly set in the RAM 919 (step 8-
9a). After that, the application rollers 207a and 207b are rotated at the newly set rotation speed R, the liquid application process is further executed, and then the peeling process is repeated. If the toner remains on the transfer paper 10 despite the peeling process again and the peeling process is within the predetermined number of times, the above step 8-9a is executed again, and the liquid applying process is executed. After that, the peeling process is repeated. Here, by increasing the rotation speed of the application rollers 207a and 207b, that is, by increasing the linear velocity ratio with the paper holding drum 601, the application roller 2
The amount of pumping up the permeation enhancing liquid 21 and the treatment liquid 20 of 07a and b is increased, and the permeation enhancing liquid 21 and the treatment liquid 20 are supplied to the transfer paper 10 in a larger amount than in the previous liquid application process.
As a result, the toner remaining without being peeled off in the previous peeling process becomes more unstable in the adhesion state with the surface of the transfer paper 10 than in the previous peeling process, and is easily peeled off from the surface of the transfer paper 10. As a result, it is possible to completely remove the toner from the transfer paper 10 while minimizing the damage on the surface of the transfer paper 10 without peeling the fibers on the surface of the transfer paper 10 together with the toner from the transfer paper 10. Become. On the other hand, if YES in step 8-8a, that is, if the toner image of the constant area cannot be peeled even after repeating the liquid applying process and the peeling process a predetermined number of times, the unremoved image is C
Detected by the CD sensor 603 and the detected data is A / D
Sent to CPU 904 via converter 918, RA
An identification mark giving unit 30 written in M919,
It is used for control in the sorting unit 40 and the like. If YES in step 8-8a, control data for opening the clamp claw 602 is sent to the parallel interface 908 even if the toner peeling process is in progress, and the driver 910 stops the operation of the solenoid 926 (step 8). -10a), the transfer paper 10 is released from the clamp claw 602, separated from the paper holding drum 601, sent to the drying unit and dried (step 8-11a), and sent to the sorting unit 40.

In the sorting unit 40, the transfer paper 10 on which the unremoved image remains based on the CCD sensor 603.
When b is conveyed, the position of the deflection claw 41 is switched so as to convey the transfer paper 10b into the guide plate 42b. As a result, the transfer paper 10b is ejected to the non-reusable transfer paper ejection tray 501b (step 8-12).

If the result of the determination in step 8-7a is YE.
If S, that is, if the residual image area is a% or less, the solenoid 92 is used as in steps 8-10a and 8-11a.
6 is turned off, the clamp claw 602 is opened to open the transfer paper 10, and the drying unit 4 dries (step 8-13).
a, 8-14a).

Next, the identification mark giving unit 30 gives the transfer paper 10 an identification mark corresponding to the number of reuses (step 8-15a). As the identification mark giving unit, for example, a punching unit, a printing unit or the like can be used. When the punching unit is used, the CCD sensor 603 detects whether or not there is a punch, and when there is a punch, the punching unit is controlled to punch, for example, next to it. Also, when using the printing unit,
For example, the CCD sensor 603 detects whether there are ◯, ×, etc. already printed on the front end of the transfer paper 10, and if there is a ◯, × mark, the control is performed so that, for example, it is printed next to it. Further, the color of the identification mark may be changed according to the number of reuses. For example, reuse count 1,
2, 3, 4. ． Against red, blue, yellow, green. ． When a red identification mark is detected by the CCD sensor 603, control is performed so that a blue identification mark is formed on the mark. This identification mark is used as data indicating the state of the transfer paper 10. Then, the transfer paper 10 provided with the identification mark is sent to the sorting unit 40.

In the sorting unit 40, on the basis of the CCD sensor 603, the transfer paper 1 on which no unremoved image remains
When 0a is conveyed, the position of the deflection claw 41 is switched so that the transfer sheet 10b is conveyed into the guide plate 42a. As a result, the transfer sheet 10b is discharged to the reusable transfer sheet discharge tray 501a (step 8-16).
a). Here, the paper discharge level sensor 505 detects the transfer paper 10a discharged onto the paper discharge tray 501a, sends data with paper through the parallel interface 908, and the CPU 904 operates the paper discharge tray motor 931. The paper ejection tray 501a is lowered. This lowering operation continues until the input from the paper discharge level sensor 505 reaches a value corresponding to the absence of paper, and the height of the paper on the paper discharge tray 501a is a constant height even if the stack amount is large. The paper is always stable.

As described above, according to the first embodiment, when the toner remains on the transfer paper 10, the coating rollers 207a and 207b are used.
The rotational speed R is increased to supply a larger amount of the penetration promoting liquid 21 and the treatment liquid 20 to the transfer paper 10 than in the previous liquid application process. It can be easily peeled off, and without peeling the fibers on the surface of the transfer paper 10 together with the toner from the transfer paper 10,

In the toner removal processing mode in this embodiment (see FIG. 7), step 8 in the first embodiment is performed.
1a, when the transfer paper 10 is sent to the position of the clamp claw 602, the clamp claw 602 closes and the transfer paper 10
Is added (step 8-1d).

[0091] Next, a ₀ 'predetermined initial rotational speed R as' rotational speed R of the sheet holding drum 601 initializes (step 8
-2d), the paper holding drum motor 933 is turned on to rotate the paper holding drum 601. This rotation speed R'is RAM9
It is set to 19.

Next, by the application rollers 207a, 207b,
The permeation promoting liquid 21 such as a surfactant and the treatment liquid 20 such as distilled water are applied to the transfer paper 10 on the paper holding drum 601 (step 8-3d). As a result, the transfer paper 1
The processing liquid 20 is allowed to penetrate into the interface between the toner particles 0 and the toner.

Next, the transfer paper 10 and the toner entangled therein are easily peeled off by heating by the heating lamp 30, and the toner is peeled off from the transfer paper 10 by the peeling roller 302 (step 8). -4d).

After the peeling process is performed, the CCD is
The sensor 603 detects the unremoved toner image remaining on the transfer paper 10 (step 8-5d). Here, the detection data by the CCD sensor 603 is the A / D converter 91.
It is sent to the CPU 904 via 8 and it is judged whether or not the ratio of the remaining image area of the unremoved image is equal to or less than the predetermined value a% (step 8-6d). In the case of NO, it is further determined whether or not the liquid applying process and the peeling process have been performed b times or more (step 8-7d). In the case of NO in step 8-7d, a value obtained by subtracting the predetermined rotation speed r'from the rotation speed R'of the peeling roller 302 which has been set in the RAM 919 up to then is newly set in the RAM 919 (step 8-8).
d). After that, the peeling roller 302 is rotated at the newly set rotation speed R ′, the liquid application process is further executed, and then the peeling process is repeated. When the toner remains on the transfer paper 10 despite the peeling process again and the peeling process is within the predetermined number of times, the above step 8-8d is executed again, and the liquid applying process is executed. After that, the peeling process is repeated. Here, the peeling roller 30
By lowering the rotation speed R ′ of 2, the paper holding drum 60
The transfer paper 10 held at No. 1 takes a longer time to pass through the facing portions of the application rollers 207a and 207b, and a larger amount of the penetration promoting liquid 21 and the processing liquid 20 are supplied to the transfer paper 10 than in the previous liquid application process. To be done. As a result, the toner remaining without being peeled off in the previous peeling process becomes more unstable in the adhesion state with the surface of the transfer paper 10 than in the previous peeling process, and is easily peeled off from the surface of the transfer paper 10. Further, by lowering the rotation speed R ′ of the peeling roller 302, the transfer paper 10 held by the paper holding drum 601 takes a longer time to pass through the portion facing the peeling roller 302, and the unit time per unit time received from the peeling roller 302 is increased. The amount of heat of the toner is increased, and the toner remaining without being peeled in the previous peeling process is softened more than in the previous peeling process, and is easily peeled from the surface of the transfer paper 10. As a result, the fibers on the surface of the transfer paper 10 are not separated from the transfer paper 10 together with the toner, and the damage on the surface of the transfer paper 10 is minimized and the fibers are not separated from the transfer paper 10 by the previous separation process. It becomes possible to completely remove the residual toner. On the other hand, step 8
In the case of YES in -7d, that is, in the case where the toner image of the constant area cannot be peeled off even after repeating the liquid applying process and the peeling process a predetermined number of times, Step 8 in the above-mentioned Example 1-
Similarly to 10a, 8-11a, and 8-12a, the clamp claw 602 of the transfer paper 10 is generated by stopping the operation of the solenoid 926.
From (step 8-9d), drying the transfer paper 10 in a drying unit (step 8-10d), and discharging the transfer paper 10b in the sorting unit 40 to the paper discharge tray 501b (step 8-11d). Is done. Note that these steps 8-9d, 8-10d, and 8
-11d indicates step 8 in the first embodiment, respectively.
Since it is similar to -10a, 8-11a, 8-12a,
The description thereof will be omitted in this embodiment.

If the result of the determination in step 8-6d is YE
In the case of S, that is, when the remaining image area is a% or less, steps 8-13a, 8-14a, 8-
Similar to 15a and 8-16a, the transfer paper 10 is released from the clamp claw 602 by stopping the operation of the solenoid 926 (step 8-12d), the transfer paper 10 is dried in the drying unit (step 8-13d), and the identification mark. An identification mark applying step (step 8-14d) on the transfer sheet 10 in the applying unit 30 and discharging of the transfer sheet 10a to the discharge tray 501a by the sorting unit 40 (step 8-1).
5d) is performed. These steps 8-12d,
Since Step 8-13d, Step 8-14d, and Step 8-15d are the same as Step 8-13a, 8-14a, 8-15a, and 8-16a in the first embodiment, respectively, in this embodiment, The description is omitted.

As described above, according to the fourth embodiment, when the toner remains on the transfer paper 10, the rotation speed R ′ of the paper holding drum 601 is decreased to make the permeation amount larger than that in the previous liquid applying process. By supplying the accelerating liquid 21 and the treatment liquid 20 to the transfer paper 10, the adhesion state of the toner remaining on the transfer paper 10 without being peeled off in the previous peeling process becomes more unstable than in the previous peeling process. The residual toner is easily peeled from the surface of the transfer paper 10 and the amount of heat received from the peeling roller 302 per unit time is increased so that the toner not peeled by the previous peeling process is peeled off by the previous peeling process. Since it is softened more than during processing and is easily peeled off from the surface of the transfer paper 10, the fibers on the surface of the transfer paper 10 are not peeled off from the transfer paper 10 together with the toner, and the damage on the surface of the transfer paper 10 is minimized. It is possible to completely remove the toner from the transfer paper 10 while it is being moved.

In addition, according to the above-mentioned Examples 1 to 4, the liquid is supplied to the transfer paper 10 to which the toner adheres, and the toner is peeled off while the liquid permeates into the interface of the transfer paper 10 with the toner. The toner can be removed without damaging the paper fiber.

Further, the transfer paper 10 is automatically sorted by the sorting unit 40, and the transfer paper 10b on which the unremoved image remains is placed on one of the discharge trays 501b of the paper receiving unit 5 and the image is completely removed. Transfer paper 10a to another paper output tray 5
01a, the transfer paper 10a on which the unremoved image remains and the transfer paper 10a on which the toner has been completely removed
The work of distinguishing from is unnecessary.

When the identification mark giving unit 30 is used as the unrecognizable means for processing the unremoved image so that it cannot be recognized, a hole as an identification mark may be formed on the unremoved image on the transfer paper 10. By controlling to print the mark, it is possible to prevent the confidential information from being leaked and the unremoved image such as the mark and the signature from being misused when the transfer paper 10 is erroneously discarded. You can

Further, since the transfer paper 10 is brought into contact with the peeling roller 302 while the surface of the transfer paper 10 is wet, and the transfer paper 10 is heated to such an extent that the transfer paper 10 can be kept wet even when the transfer paper 10 is separated from the peeling roller 302, Even when the surface 302 is made of a material having toner adhesiveness, it is possible to prevent the surface itself of the transfer paper 10 from adhering to the surface of the peeling roller 302 and cause separation failure, and the separated part of the transfer paper 10 is peeled off. Retransfer of the toner due to re-contact with 302 can be prevented.

In the first to fourth embodiments, a plurality of peeling rollers may be provided to remove the toner.

In the first to fourth embodiments, the drive of the coating roller 207a is prohibited during the re-peeling process so that the penetration promoting liquid 21 is not supplied to the transfer paper 10 on the paper holding drum 601. You may That is, since the transfer paper 10 that has been subjected to the re-peeling process in the toner removing device having the above-mentioned configuration has not passed through the drying unit 4, the penetration promoting liquid 21 supplied during the first peeling process.
Remains on the surface of the transfer paper 10, and it is not necessary to additionally supply the penetration promoting liquid 21. Therefore, by not supplying the penetration promoting liquid 21 during the re-peeling process as described above, it is possible to prevent the permeation promoting liquid 21 from being excessively supplied to the transfer paper 10 and wasteful consumption of the penetration promoting liquid 21. It can be prevented.

Further, in the present embodiment, the surface roughness of the peeling roller 302 is made different in order to make the toner peeling ability of the plurality of peeling rollers 302 different, but instead of this or in addition to this, a plurality of peeling The surface of the roller 302 is made of materials having different amounts of adhered toner per unit contact surface,
The plurality of peeling rollers 302 may have different toner peeling capacities. In this embodiment, for example, a first peeling roller made of a resin or the like having the same or similar SP value as the toner component resin, and the above S
A second peeling roller made of a resin or the like having an SP value outside the P value is provided, and when the image density on the transfer paper 10 is equal to or higher than a predetermined density, a peeling process is performed by the second peeling roller. Then, the peeling process may be performed by the first peeling roller, and when the image density is not higher than the predetermined density, the peeling process may be performed by using the first peeling roller. In this case, a resin having the same or similar SP value as that of the toner component resin has a small interfacial tension with the toner and has a high adhesive strength between the two, so that the toner peeling process can be efficiently performed. In addition, from the theoretical consideration of adhesive or adhesiveness,
When the surface tension of the adhesive and the adherend (solid to be adhered) are equal and have almost the same polarity, the interfacial tension becomes minimal and the adhesive strength is maximized. When the resin having the SP value of 1 has the same kind of polar group, the interfacial tension becomes extremely small and the adhesive strength is further improved. The SP value that is the same as or similar to the toner component resin is, for example, in the following range. Examples of resins having an SP value smaller than the lower limit of the above range include polytetrafluoroethylene, polydimethyl silicone, butyl rubber, and polyethylene. Examples of resins having an SP value larger than the upper limit of the above range include polyvinylidene chloride, nylon, and polyacrylonitrile.

Further, in the toner removing devices of the above-mentioned first to fourth embodiments, the identification mark giving unit 30 and the paper receiving unit 5 are provided.
A sorting unit 40 for sorting the transfer paper 10 is arranged between the sheet and the sheet. However, the sorting unit 40 is arranged immediately after the drying unit 4, and the identification mark giving unit 30 is provided for the unremoved image in the discharge cassette 5. May be arranged immediately before the paper discharge tray 501b for discharging the remaining transfer paper 10b. In this case, the unremoved image (image by stamp, writing, etc.) remaining on the transfer paper 10 after the peeling is applied to the CCD sensor 60.
3, the transfer paper 10 on which the unremoved image has been detected is sorted by the sorting unit 40, and then an identification mark is attached by the identification mark giving unit 30 on the one discharge tray 501b of the discharge cassette 5. Is discharged to. On the other hand, the transfer paper 10a from which the image has been completely removed does not pass through the identification mark giving unit 30 after being sorted by the sorting unit 40,
The sheet is discharged onto another sheet discharge tray 501a.

Further, although the present invention is applied to the transfer paper 10 on which an image is formed by the transfer type electrophotographic copying machine in the above-mentioned first to fourth embodiments, other images such as a facsimile, a printer and a printing machine are used. It can also be applied to an image carrier such as recording paper used in the forming apparatus.

[0106]

According to the first to eleventh aspects of the present invention, after the image forming substance is peeled from the image holding member, if the image forming substance remains on the image holding member, for example, If the remaining amount of the image forming substance before the peeling process is compared with the remaining amount and the remaining amount is a predetermined ratio or more with respect to the attached amount, the device is controlled according to the remaining state of the image forming substance, Since the surface of the peeling member is again brought into contact with the image-forming substance remaining on the image carrier to peel off the image-forming substance remaining on the image carrier, the image-forming substance on the image carrier is peeled off. Even if all the image-forming substances cannot be removed from the image carrier by one image-forming substance peeling operation, it is possible to satisfactorily remove all the image-forming substances remaining on the image carrier.

Further, in particular, according to the invention of claim 5, a larger amount of the adhesion destabilizing substance is supplied at the time of re-peeling than at the time of performing the first peeling process. Since the state of adhesion to and is further destabilized than when the first peeling process is performed, the image forming substance remaining on the image carrier can be satisfactorily removed at the time of re-peeling.

In particular, according to the invention of claim 6, the contact pressure of the peeling member with respect to the image carrier is increased at the time of re-peeling as compared with the time of the first peeling process, whereby the remaining image forming substance is On the other hand, since the peeling member is pressed more strongly than when the first peeling process is performed, the image-forming substance remaining on the image carrier can be satisfactorily removed during re-peeling.

Further, in particular, according to the invention of claim 7, the heating temperature for the heat-meltable image forming substance by the heat softening member of the peeling member is raised at the time of re-peeling than at the time of performing the first peeling process. , The remaining image-forming substance
Since it is softened more than when the peeling process is performed for the second time, the image-forming substance remaining on the image carrier can be favorably removed at the time of re-peeling.

Further, in particular, according to the invention of claim 8, the adhesion destabilizing substance is impregnated into the interface portion between the surface of the image holding member and the image forming substance at the time of re-peeling more than at the time of performing the first peeling process. The moving speed of the image carrier at the portion facing the impregnating means and the peeling member is reduced, whereby the time for feeding the destabilizing substance by the impregnating means is increased to increase the amount of the destabilizing substance feeding, Since the time for peeling off the image forming substance by the peeling member is lengthened, the image forming substance remaining on the image carrier can be favorably removed at the time of re-peeling.

Further, in particular, according to the invention of claim 9, since the operation of the accelerating substance impregnating means is prohibited at the time of re-peeling and the penetration promoting substance is not supplied to the surface of the image carrier, it is supplied at the time of the previous peeling. When the penetration promoting substance remains on the surface of the image carrier, excessive supply of the penetration promoting substance can be prevented, and wasteful consumption of the penetration promoting substance can be prevented.

Further, in particular, according to the invention of claim 10,
In removing the image-forming substance from the surface of the image carrier, the adhesion between the surface of the image carrier and the image-forming substance is destabilized. Can also remove imaging material while minimizing damage to the fibrous material.

Further, in particular, according to the invention of claim 11,
Non-peelable image formation, even if the re-peel process is performed a predetermined number of times, for example, an image is imprinted with a red stamp, a Shachihata (trade name) mark, etc. When the substance remains on the image carrier, the subsequent re-peeling process is prohibited, so that unnecessary peeling process can be avoided. Further, depending on the user, if the residual amount of the image forming substance on the image carrier after the peeling process is small enough to make the copy image legible when the image carrier is reused as copy paper, In some cases, the image-forming substance may remain on the image carrier. Further, some users dare to reuse the image carrier after the peeling process, for example, as memo paper even if it cannot be reused as copy paper, for example, even if the surface of the image carrier is excessively peeled off. It may be desirable to repeat the stripping process to remove the imaging material substantially completely. According to the ninth aspect of the present invention, if the image forming substance remains on the image carrier even after the re-peeling process is performed a predetermined number of times, the subsequent re-peeling process is prohibited. When the re-peeling process is prohibited, the user can be given the opportunity to select whether the image forming substance may remain as it is, or the peeling process may be repeated to remove the image forming substance almost completely.
