[0009]

An embodiment of the present invention will be described below with reference to the drawings.

The reproducing apparatus (1) shown in FIG. 1 has a construction in which the printing on the recording material is scraped in the cleaning liquid in the dipping tank, and a paper feeding means (2) for feeding the recording material into the reproducing apparatus. Two
1), a cleaning liquid is stored in the immersion tank for swelling the printing portion in advance for a predetermined time by immersing the recording material for a predetermined time, and a physical treatment is applied to the surface of the recording material in which the printing portion is raised. A print removing means (4) for removing the printing portion, a flow means (5, 51-55) for flowing the cleaning liquid in the dipping tank so as to face the conveying direction of the recording material, and a recording material to which the cleaning liquid adheres is dried. The drying unit 60 includes a drying unit 60, a discharging unit 7 that discharges the dried recording medium as recycled paper, and a conveying unit that conveys the recording medium.

Reference numeral (10) in the drawing denotes a recording body, which is a so-called OHP sheet such as a paper or a polyester film on which a toner image Ta containing at least a resin component is recorded. These recording bodies are printed by so-called OA devices such as conventionally known copying machines, printers, and facsimiles.

The sheet feeding means provided in the upper left portion of the reproducing apparatus in the figure conveys the recording body (10) to the opening (I) into which the recording body (10) is introduced. It is composed of a paper feed tray (2) provided as described above. Paper tray (2)
The recording medium (10) may be manually fed by an operator, or by using an automatic document feeder (ADF) used for automatically feeding a document in a copying machine or the like,
Paper may be fed continuously.

The recording body (10) pulled out from the paper feed tray (2) by the paper feed roller (21) is stopped by the front end thereof being sandwiched between the feed roller pair (9a) and (9b). In the figure, the sensor (S1) sends a start signal when one end of the recording body (10) placed on the paper feed tray (20) enters the inside of the apparatus (1) through the opening (I). It is set so that the feed rollers (9a) to (9e) are rotated and driven by driving means (motor or the like) not shown based on the output. In addition, the start signal may be output only when the operator's input to the separately provided switch (S2) is detected.

The feed roller (9a) is pressed against the feed roller (9b) with a constant pressure with a conveyor belt (8a), which will be described later, in between. In the present invention, at least one of the pair of feed rollers (9a) and (9b) is an elastic body,
For example, it is preferable to use a urethane roller having a roughened surface.

Conveyor belts are provided on the feed rollers (9b) and (9c).
(8a) and the feed belts (8b) are stretched around the feed rollers (9d) and (9e). Conveyor belt (8a), (8
b) is rotationally driven at a predetermined speed in the direction of the arrow in the drawing with the rotation of the feed rollers (91b) to (91e). On the conveyor belt (8a), the pressing rollers (91a), (91b) and
(91c), and on the conveyor belt (8b) again, a pressing roller
(91d) and (91e) are pressed. After the recording material is printed and removed by the print removing means (4) while being transferred at a predetermined speed between the conveyor belt and the pressing roller in the cleaning liquid (30) stored in the immersion tank (3). Then, it is conveyed to the calender roll pair (11a), (11b) through the drying means.

The rotation drive of the feed roller pairs (9a) and (9b) and the feed rollers (9c) to (9e) in the dipping tank is controlled by a sensor (S3), and the recording medium (10) is set to a calendar roll pair ( It is configured to drive until 11a) and (11b) are reliably reached. Alternatively, the sensor (S3) may not be provided, and a predetermined time may be managed by a timer to drive the rotation.

By moving the conveyor belt (8a), the immersion tank (3)
The recording body (10) transferred therein is temporarily stopped here and immersed in the cleaning liquid (30) for a predetermined time. The fixing toner (Ta) on the recording medium swells due to the action of the cleaning liquid. The cleaning liquid used does not dissolve the dye component such as the charge control agent and the colorant component such as facial dye in the toner, but swells the resin component that constitutes the toner to make the toner plastic and the surface from the inside of the recording medium. Use the one that has the property of raising the toner image. As the cleaning liquid used in the present invention, for example, Tosclean D (manufactured by Choso Sangyo Co., Ltd.), which is commercially available as an aqueous cleaning agent, can be used. Tos Screen D contains a tol oil fatty acid ester, a tol oil fatty acid and a surfactant, and has an acid value of about 2.1 mgKOH / g, a specific gravity of 1.020 (20 ° C) and a pH of 7
It is a pale yellow transparent liquid with physical properties of ± 0.5 (15 ° C). Toscreen does not contain any compound of fluorine and chlorine carbon, which is said to destroy the ozone layer.
Further, since it is harmless to the human body and nonflammable (no flash point), it is extremely suitable for use in a paper recycling apparatus in a normal office environment like the present invention.

The recording medium is immersed in the cleaning liquid under the following conditions.
It may be appropriately set in consideration of the types of the recording material, the printing material (toner), the cleaning liquid, and the like. In any case, the fixing toner (Ta) on the recording material is recorded by the printing removing means described later. Make it easy to detach from above. The dipping time varies depending on the type of the recording medium (10), the printing material, the cleaning liquid, etc., but it is generally preferable to soak for several tens of seconds to several minutes. In this embodiment, Toclean D (manufactured by Choso Sangyo Co., Ltd.), which will be described later, is used as the cleaning liquid, and is fixed at 30 seconds in order to use this under optimum conditions. After the lapse of 30 seconds, each feed roller is driven and the recording material is transferred to a step of removing print.

Then, a physical force is applied to the surface of the recording medium by the print removing means (4) to scrape the printed portion. In this embodiment, a rotary brush is provided as the print removing means.
As shown in FIG. 4, while rotating the brush bristles of the rotary brush so as to slide on the surface of the recording medium in the dipping tank (3), the recording medium is conveyed in the conveying direction (arrows a and b directions) or orthogonally. It is reciprocated along the direction (directions of arrows c and d).
As a result, the printed portion can be scraped off efficiently without damaging the surface of the recording body (10).

As the material for the bristles of the rotary brush, polymer fibers such as nylon, acryl and polyester, or fibers such as wool are preferably used.

The form of the print removing means (4) is not limited to the above rotary brush form. For example, a cloth belt (web) stretched between driving rollers can be used. Use a cloth woven of fibers,
The removal effect can be further enhanced by pressing the blade against the surface of the web to scrape the swollen toner or other dirt adhering to the web into the collection box. Further, an elastic blade made of metal, rubber or the like can be used as the print removing means. These are configured to scrape off the toner from the surface of the recording body (10) by combining a pressure contact means (spring or the like). Further, the print removing means is not limited to the solid friction method as described above, and may be a method in which the cleaning liquid is strongly sprayed as a jet stream from the slit nozzle onto the recording medium to release the toner. The above means can be used in combination as appropriate.

In the present embodiment, the recording material is temporarily stopped in the dipping tank, sufficiently immersed in the cleaning liquid, and then the print removing process is performed by the print removing means. However, the recording material is not stopped. The print removing means may simultaneously perform the print removing processing while conveying the inside of the immersion tank at a predetermined speed. The moving speed of the recording material in the dipping tank is appropriately determined from the balance between the print removal efficiency and the reproducing speed of the recording material.

The toner (Tb) separated from the surface of the recording medium by the above-mentioned print removing treatment is suspended and suspended in the cleaning liquid or is deposited as large plastic particles. If these are left in the cleaning liquid, they are reattached to the cleaned recording material and re-adsorbed, resulting in image noise such as black spots. Therefore, it is necessary to provide a flow means for circulating the cleaning liquid at the bottom of the immersion tank (3) to keep the cleaning liquid in the immersion tank always clean.

In the figure, (5) is a circulation path for circulating the cleaning liquid, and the cleaning liquid (30) is filled with the inlet (5).
A pump (53) is provided so as to take in from (1) and discharge from the outlet (52). A filter is provided on the upstream side of the pump (53) in the circulation direction of the cleaning liquid.
(54) is provided. Dipping tank with this filter
Since the toner (Tb) and other impurities floating in (3) are collected, the cleaning liquid in the immersion tank (3) is always kept at a constant cleanliness. The filter material (55) is appropriately replaceable. As the material of the filter material, for example, glass wool, activated carbon, cloth of natural fiber, or the like can be used.

Further, by making the circulating direction of the cleaning liquid in the dipping tank face the conveying direction of the recording medium, a cleaning liquid (30c) which is always clean for the recording medium is provided.
Will be supplied. Therefore, it is possible to prevent the toner or the like that has been once peeled from the recording medium and suspended or settled in the cleaning liquid from re-adhering or re-adsorbing to the recording medium, and it is possible to obtain a reproduced recording medium with high whiteness. Further, the cleaning liquid can be repeatedly used until its action is reduced, which is very economical.

Conveyor belt for transferring the recording material in the immersion tank
As (8a) and (8b), for example, a thin film, an elastic body, a non-woven fabric, a cloth in which fibers are knitted, or a plate-like material made of metal, polymer, or steel is preferably used. It is necessary to select a material that does not easily corrode. Further, the conveyance force of the recording medium (10) can be improved by roughening or meshing the belt surface.

Holding roller (91a) and holding roller (91b)
Distance, distance between holding roller (91b) and holding roller (91c), distance between holding roller (91d) and print removing means (4), distance between print removing means (4) and holding roller (91e) However, when the length of the recording medium (10) to be regenerated is longer, the recording medium (10) floats up in the dipping tank (3), so that the print is not sufficiently removed. Therefore, record each distance
It is desirable to set the length shorter than the length in the conveyance direction of (10). That is, in the reproducing apparatus in which B5 size vertical feed, A4 size vertical feed, B4 size vertical feed, and A3 size vertical feed can be selected at any time as the paper feed size of the recording medium, the distance between the respective restraining rollers is set to B5 size. Make it shorter than the vertical length. However, the recording medium (10) is a cleaning liquid.
When it is wet by (30) and is in close contact with the conveyor belts (8a), (8b), it is not necessary to set the distance between the respective restraining rollers as described above in order to prevent lifting.

In the immersion tank (3), ultrasonic vibrating means or heater may be appropriately provided in order to enhance print removal. The cleaning liquid often causes a difference in the print removing effect depending on the temperature thereof, and appropriately adjusting the temperature of the cleaning liquid with a heater leads to the improvement of the removing effect. The optimum temperature varies depending on the type of the cleaning liquid (30) and cannot be specified unconditionally, but it is generally preferable to keep it at about 30 to 50 ° C.

The recording body on which the print removal processing has been completed as described above is transferred to the drying means via the transport guide plate (12) and is dried there. The drying means (6) is composed of a pair of rubber rollers (6a) and (6b) which are in pressure contact with each other, and a heater (60) which heats the rollers (6b) from the inside.

The drying means is not necessarily in the form of heating by heat transfer, but may be in the form of blowing warm air or utilizing radiant heat from a xenon lamp or the like. The heating temperature varies depending on the cleaning liquid (3) used and the type of the recording medium (10), but is generally 40 to 90 ° C.
The temperature is preferably 50 to 60 ° C. If the heating temperature is lower than this, the drying time becomes long and not suitable for practical use. On the other hand, if the heating temperature is too high, the OHP may be deformed or the recording medium may be damaged such as yellowing of the paper.

The recording medium (10) which has passed through the drying means is conveyed to the calender roll pair (11a), (11b). The calender roll pair is a pair of metal rolls pressed against each other. By passing the recording medium (10) between the rolls, fine scratches on the surface of the recording medium received during the printing process,
For example, a fine defect is repaired by a stapler or the like, and a habit such as bending is removed to some extent. Further, in the case of paper, gloss treatment can be performed by this treatment.

A heater may be included in the calendar roll so that it also has a drying function. As a result, it is not necessary to separately provide a drying means, and the process can be simplified.

The recording medium (10) that has passed through the pair of calender rolls (11a), (11b) is discharged as recycled paper (100) from the discharge section (O) onto the discharge tray (7), and a series of reproduction processing is performed. The operation ends.

As described above in detail, in this embodiment, the recording medium is soaked in the cleaning liquid in the dipping tank in advance to sufficiently swell the toner, and then the toner is peeled off by the print removing means. ing. Therefore, the print removing means
By (4), the physical force applied to the surface of the recording medium can be made as small as possible, and the printing process can be reliably performed without damaging the recording medium (10). In addition, the print removal process is performed in the flow of the cleaning liquid, and since the fresh cleaning liquid is constantly supplied to the surface of the recording material, it is necessary to provide recycled paper with high whiteness that can be sufficiently reused. You can Further, in the reproducing apparatus of the present invention, by appropriately selecting the cleaning liquid, not only the printed output but also the ball-point pen written on the recording medium,
It is also possible to simultaneously remove highlighter pens, magic ink, red ink, pencils, and other inks.

FIG. 2 shows a second embodiment of the reproducing apparatus of the present invention.

FIG. 2 shows a recording medium fed by the sheet feeding means.
(10) is dipped in the cleaning liquid (30) in the dipping tank (3), and after the print removing means (4) removes the print, it is obliquely upward from the cleaning liquid by the conveyor belt (8c). This is a reproducing apparatus having a structure in which a clean cleaning liquid is rinsed from the nozzle (52a) on the surface of the recording medium while being conveyed to the pulling and drying step. The conveyor belt (8c) is
It moves in accordance with the rotational drive of the feed rollers (9f) and (9g).

The clean cleaning liquid discharged from the nozzle (52a) flows into the dipping tank (3), and then the recording medium.
A flow opposite to the moving direction of (10) is formed and the inlet
It is circulated from (31) to the filter part (54). By this action, the dirty cleaning liquid (30b) containing the floating toner particles (Tb) rapidly flows in the direction opposite to the moving direction of the recording medium in the print removed portion. On the other hand, the cleaned portion of the recording medium moves to the nozzle (52a) which is the outlet of the clean cleaning liquid (30c), so that it hardly touches the floating toner particles (Tb). . Therefore, redeposition of these toner particles on the recording medium is prevented as much as possible.

Further, temporarily, a floating toner on the recording medium in the dipping tank.
Even if the particles (Tb) are re-adhered, the re-adhered toner is sufficiently washed away by receiving a strong rinse of the clean cleaning liquid while the recording medium (10) is being pulled up obliquely upward. Therefore, these toner particles (T
It is prevented that the process b) is carried on to the next step of drying.

FIG. 3 shows a third embodiment of the reproducing apparatus of the present invention.

In this embodiment, after the recording medium (10) fed by the paper feeding means is dipped in the cleaning liquid (30) in the dipping tank (3), it is once drawn out from the cleaning liquid to remove the print. A playback device configured to perform.

In the figure, (8d) is a conveyor belt for conveying the recording medium. The conveyor belt is a roller by a driving means not shown
It moves with the rotational drive of (9b) and (9h). The recording material is transferred at a predetermined speed between the conveyor belt and the pressing rollers (91f), (91g) and (91h) in the cleaning liquid stored in the immersion tank. Toner (Ta) in immersion tank (3)
After being sufficiently swelled, the recording medium is pulled up obliquely upward from the dipping tank (3) by the conveyor belt (8d). Here, the toner on the recording medium is peeled off by the print removing means (4). Nozzle (52
The cleaning liquid is discharged from a). The flow rate of the cleaning liquid is adjusted so that the surface of the recording material is washed out. The toner peeled off from the recording medium by the print removing means is washed away by the cleaning liquid discharged from the nozzle (52a), flows into the dipping tank, and floats or precipitates. These impurities are collected by a filter (54) provided separately. The cleaned cleaning liquid is again used in the nozzle.
It is discharged from (52a).

With the above arrangement, even if the floating toner particles (Tb) touch and re-attach to the recording medium after the completion of the print removing process, the recording medium (10) can be cleaned cleanly while being obliquely pulled upward. The redeposited toner is thoroughly rinsed because it receives the rinsing liquid. Therefore, the toner particles on the recording medium (10) do not proceed to the next step of drying, and the generation of image noise such as black spots can be suppressed.

The cleaning liquid used in the above-mentioned regenerating apparatus of the present invention will be described below.

When the printed portion is removed without pulping the paper, the effect of removing the print is very low even if the surfactant alone is directly applied to the recording medium, and the toner is lifted from the surface of the paper. A substance having a function of swelling the toner is used together. Therefore, it is preferable to use a cleaning liquid containing at least a higher fatty acid ester, a surfactant and water.

Specific examples include the following.

The fatty acid of the higher fatty acid ester is a saturated or unsaturated fatty acid such as lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid,
Linoleic acid, erucic acid, ricinoleic acid, abietic acid,
Examples include rosin acid, coconut oil, linseed oil, beef tallow, whale oil and the like. The higher fatty acid ester is a fatty acid and a hydroxy compound, for example, alcohols such as ethanol and n-butanol, polyhydric alcohols such as ethylene glycol, glycerin pentaerythritol sorbitol, glycols such as diethylene glycol, dipropylene glycol and polyethylene glycol, and Ethyl cellosolve,
Refers to esters with cellosolves such as butyl cellosolve. Among them, tall oil fatty acid containing oleic acid and linoleic acid in a ratio of about 6: 4, and in addition, palmitic acid, stearic acid, and some unsaponifiables Esters are particularly preferred. As the alcohol for esterifying tall oil fatty acid, ethylene glycol, polyethylene glycol, ethoxyethanol, butoxyethanol, etc., preferably butoxyethanol, ethylene glycol, ethoxyethanol are used.

The content of the higher fatty acid ester in the cleaning liquid is 60 to 5% by weight based on the total amount of the cleaning liquid,
It is desirable to use it in the range of preferably 40 to 20% by weight. If it is used in an amount of more than 60% by weight, the solubility of the toner becomes too high, and the dissolved toner tends to redeposit on the paper. On the other hand, if the amount is less than 5% by weight, when used in the range, the swelling property with respect to the toner becomes poor and the effect of removing the print becomes low.

As the surface active agent, an anionic surface active agent, a nonionic surface active agent, a cationic surface active agent and an amphoteric surface active agent can be used. The addition of the surfactant serves to surround the toner after printing removal so that the toner does not redeposit on the paper surface.

Illustrative examples of the surfactant include fatty acid salts, alkyl sulfate ester salts, alkylbenzene sulfonates, alkylnaphthalene sulfonates, alkylsulfosuccinates, alkyldiphenyl ether disulfonates as anionic surfactants. , Alkyl sulfosuccinates, naphthalene sulfonic acid formalin condensates, polycarboxylic acid polymer surfactants and the like. Examples of the nonionic surfactant include polyoxyethylene alkyl ether, polyoxyethylene alkyl allyl ether, oxyethylene-oxypropylene copolymer, sorbitan fatty acid ester, polyoxyethylene sorbitan fatty acid ester, and polyoxyethylene alkylamine. Examples of the cationic surfactants and amphoteric surfactants include alkylamine salts, quaternary ammonium salts, alkylbetaines, amine oxides and the like. These surfactants may be used alone or in admixture of two or more.

A particularly preferred surfactant has the formula: RO
An ethylene oxide addition type nonionic surfactant represented by (CH ₂ CH ₂ O) _n H (wherein R represents an alkyl group or an alkylphenyl group, n represents an integer of 1 to 10).

The amount of the surfactant used in the cleaning liquid is 0.1 to 10% by weight, preferably about 1 to 3% by weight based on the total amount of the cleaning liquid. If it is used in an amount of more than 10% by weight, bubbles and the like increase and handling becomes difficult. If the amount is less than 0.1% by weight, the toner once removed from the surface of the recording material may reattach to the paper.

Water is preferably added to the cleaning material of the present invention. Pulp fibers are hydrogen-bonded to paper, but the addition of water has a function of breaking this bond, which makes it easier to remove the toner entangled between the fibers.

Water is contained in the cleaning substance in an amount of 1 to 80% by weight, preferably 20 to 70% by weight, more preferably 30 to 60% by weight, based on the whole cleaning substance. If too much water is used, weaken the binding force between paper fibers,
When rubbing the paper surface with a rotating brush, web, blade, etc., it damages the paper surface or destroys the fibers of the paper. Further, it is not preferable because it takes too much labor to dry after removing the print. If the amount of water used is less than 1% by weight, the effect of spreading the fibers of the paper is not obtained, and the cleaning substance is not properly permeated into the paper.

Further, by incorporating an organic acid in the cleaning substance, it is possible to improve the permeability to toner, paper and the like. Examples of such an organic acid include higher fatty acids that can be used to previously synthesize higher fatty acid esters. In addition, formic acid, acetic acid, benzoic acid and the like are exemplified.

Further, as a cleaning material, for example, methanol, ethanol, n-butanol, isopropanol, ethoxyethanol and the like and xylene, toluene, acetone, THF, dioxane, dichloromethane and the like are mixed with the cleaning material within a range not impairing the effect of the present invention. An organic solvent that swells the toner such as the above may be contained.

[0056]

According to the reproducing apparatus of the present invention, the reproducing process can be performed by a simple operation without shredding the recording medium. Further, by lifting the printed portion from the recording medium and scraping it off, it is possible to reliably perform the printing process without damaging the surface of the recording medium. Furthermore, by performing the print removal process in running water, it is possible to prevent the floating in the cleaning liquid and the reattachment of the precipitated toner to the recording medium as much as possible, and the reproduction recording with high whiteness without image noise such as black spots. You can get the body.
