Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for processing sheet-like media such as paper and film sheets in a liquid, and more particularly to the construction of a portion for drying the media taken out from the liquid.

[0002]

2. Description of the Related Art Conventionally, as an apparatus for processing a sheet-shaped medium in a liquid while transporting it, a sheet on which an image is formed with toner or a synthetic resin film for OHP is dipped in a toner deinking solution, and the sheet is formed. There is known a device for removing toner from the toner and reproducing the toner.

[0003]

However, paper and OHP
Films are remarkably different in water absorbency and heat deformability. Specifically, since paper has a higher water absorption than a film, it cannot be reused unless it is dried by applying sufficient heat after being taken out from the liquid, but since the film absorbs no or almost no water, it absorbs moisture on the surface. It can be reused immediately by simply removing it. Therefore, when removing the water content of the film, if the same amount of heat as that of paper is applied to the film, the film may not be easily deformed, causing wrinkles, waviness, melting and the like.

[0004]

Therefore, an object of the present invention is to provide an apparatus for drying a sheet processed in a liquid in accordance with its type, and wet a plurality of types of sheet media. In a processing device for processing, a drying means for drying the medium that can operate under a plurality of operating conditions, a determining means for determining the type of the medium, and an operating condition of the drying means depending on the determination result of the determining means. And a control means for controlling the operation.

[0005]

According to the sheet-shaped medium processing apparatus of the present invention, the type of sheet to be processed is discriminated, and the drying means is operated under conditions suitable for the sheet in accordance with the discrimination result. For example, if the medium is paper, this medium is heated to remove the moisture contained therein, while if the medium is an OHP film, only the moisture adhering to the surface is removed without applying heat. To be done. for that reason,
The film medium is not permanently deformed, and the wasteful consumption of heat is prevented.

[0006]

The deinking liquid 16 will be described. A deinking solution for deinking a printing surface visualized by a printing material containing at least a resin on a recording medium such as a copy sheet is a component that dissolves or swells the resin of the printing material, and the deinked printing material is re-papered. A component that has the function of aggregating the printing material after deinking to prevent it from adhering to the paper, swelling the fibers of the paper, which is one of the recording materials, and makes the printing material easily detach from the paper fibers. When necessary, the components, components that contribute to the shortening of the deinking time by increasing the penetrability of the deinking liquid into the printing material and the paper, and the like are mixed and manufactured. Examples of components that dissolve or swell the resin of the printing material include divalent organic acid monoesters, glycol ethers, and other organic solvents.

The divalent organic acid monoester will be specifically described. Examples of the divalent organic acid of the monoester of the divalent organic acid include saturated or unsaturated fatty acids such as oxalic acid, malonic acid, succinic acid and glutaric acid. , Adipic acid, pimelic acid, suberic acid, mazelaic acid, sebacic acid, maleic acid or fumaric acid, or aromatic fatty acids such as phthalic acid, isophthalic acid and terephthalic acid can be used. Among these, saturated fatty acids such as oxalic acid, malonic acid, succinic acid, glutaric acid, adipic acid, pimelic acid, suberic acid, azelaic acid and sebacic acid are preferable.

Examples of alcohol components of monoesters of divalent organic acids include monohydric alcohols (which may be linear or branched) such as methanol, ethanol, propanol, butanol, pentanol, ethylene glycol, and glycerin. Polyhydric alcohols such as pentaerythritol and sorbitol, glycols such as diethylene glycol, dipropylene glycol and polyethylene glycol, or cellosolves such as ethyl cellosolve and butyl cellosolve can be used.
These alcohols can be used alone or in admixture of two or more.

The monoester of a divalent organic acid is provided by an esterification reaction of the above divalent organic acid with an alcohol or by a hydrolysis reaction of a diester of a divalent organic acid. Preferred monoesters of divalent organic acids have the general formula:

[0025]

Embedded image HOOC- (CH ₂ ) _n —COOR ₁ (in the formula, R 1 represents an alkyl group of carbon acids 1 to 5 and n represents an integer of 0 to 8).

Specifically, oxalic acid monoester (HO
OC-COOR ₁ ), malonic acid monoester (HOOC
-CH ₂ -COOR _1), succinic acid monoester (HOO
_{C- (CH 2) 2 -COOR 1} ), glutaric acid monoester _{(HOOC- (CH 2) 3 -COOR} 1), adipic acid monoester _{(HOOC- (CH 2) 4 -COOR} 1),
Pimelic acid monoester (HOOC- (CH _{2) 5} -CO
OR ₁ ), suberic acid monoester (HOOC- (C
H _{2) 6} -COOR _1), azelaic acid monomethyl ester (H
_{OOC- (CH 2) 7 -COOR 1} ), sebacic acid monoester _{(HOOC- (CH 2) 8 -COOR} 1) and the like. Of course, the divalent organic acid monoester may be used alone or in combination of two or more kinds.

The divalent organic acid monoester is mixed with water, which is a material that swells the fibers of the recording material, paper, due to the presence of the carboxylic acid group, and makes the printing material easily separated from the paper fibers. It dissolves and has excellent penetrating power to printing materials. Due to the presence of ester groups, swelling in toner,
It is considered that the dissolving power is secured.

The total amount of the deinking solution used is 5 to 60% by weight, preferably 20 to 40% by weight. 5
If it is less than wt%, the swelling property and solubility in the printing material will be inferior and there will be no deinking effect. If it is more than 60 wt%, the dissolving power in the printing material will be too high and it will easily re-adhere to paper.

Next, the glycol ether will be specifically described. For example, ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol monoisopropyl ether, ethylene glycol monobutyl ether, ethylene glycol monoisoamyl ether, diethylene glycol monomethyl ether, diethylene glycol monoethyl ether. Ethyl ether,
Examples thereof include diethylene glycol monobutyl ether, triethylene glycol monomethyl ether, dipropylene glycol monomethyl ether, dipropylene glycol monoethyl ether, tripropylene monomethyl ether, etc. One kind or a mixture of two or more kinds may be used.

Glycol ethers are also permeable to paper. The total amount of the deinking solution used is 5 to 95% by weight, preferably 10 to 80% by weight. If the amount is less than 5% by weight, the swelling property and the solubility to the printing material are inferior and the deinking effect is not exerted, and if it is more than 95% by weight, the dissolving power to the printing material is too high and the redepositing on the paper easily occurs.

More specifically, other organic solvents include those which do not mix with water and dissolve or swell the toner. For example, benzene, toluene, xylene, dichloromethane, methyl ethyl ketone, methyl acetate, ethyl acetate, ethyl ether, propyl ether, butyl ether, diisobutyl ketone, butyl acetate, ethyl butyl acetate, methyl propionate, ethyl propionate and the like are preferably used. These organic solvents may be used alone or in admixture of two or more. The total amount of deinking liquid added is 10 to 70% by weight, preferably 2
It is used in the range of 0 to 60% by weight. If the amount is less than 10% by weight, the swelling property and the solubility to the printing material are inferior and the deinking effect is not obtained, and if the amount is more than 70% by weight, the dissolving power to the printing material is too high and the redepositing on the paper easily occurs.

In order to prevent the deinked printing material from adhering to the paper again, examples of the component having an action of aggregating the printing material such as toner after deinking include a surfactant, a higher fatty acid and a higher fatty acid. Esters can be mentioned.

The surfactant will be specifically described below.
Anionic surfactants, nonionic surfactants, cationic surfactants and amphoteric surfactants can be used.
Conventionally, a surfactant has been used as a deinking agent for pulped waste paper, but when the printing material is a resin, the deinking action is very effective even if the surfactant alone is directly applied to the recording medium. Since it is weak, the present invention preferably contains a component that dissolves or swells the resin as described above.

Fatty acid salts as anionic surfactants,
Alkyl sulfate ester salts, alkylbenzene sulfonates, alkylnaphthalene sulfonates, alkyl sulfosuccinates, alkyl diphenyl ether disulfonates, alkyl sulfosuccinates, naphthalene sulfonic acid formalin condensates, polycarboxylic acid polymer surfactants, etc. It can be preferably used.

As the nonionic surfactant, polyoxyethylene alkyl ether, polyoxyethylene alkyl allyl ether, oxyethylene-oxypropylene copolymer, sorbitan fatty acid ester, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene alkylamine and the like are preferable. Can be used for.

As the cationic surfactant or amphoteric surfactant, alkylamine salts, quaternary ammonium salts, alkylbetaines, amine oxides and the like are preferable. Each of the above surfactants may be used alone or in combination of two or more. A particularly preferred surfactant has the chemical formula: RO
(CH ₂ CH ₂ O) _n H (wherein R represents a C21 to C22 alkyl group or an alkylphenyl group, n represents an integer of 1 to 10) and is an ethylene oxide addition-type nonionic surfactant. is there.

The surfactant surrounds the deinked printing material and has the effect of preventing re-adhesion to the recording medium. further,
When the recording medium is plain paper or the like, it also has an action of entering the inside of the stitch structure of the paper to surround the printing material and facilitating deinking of the printing material that has penetrated deep into the fiber. Furthermore, when the liquid that dissolves or swells the printing material is insoluble in water and water is used as the deinking agent, it also has a function of forming a stable deinking liquid of an O / W type emulsion.

The amount added in the entire deinking solution is 0.1-10.
It is used in the range of wt%, preferably 0.1 to 5 wt%. If it is less than 0.1% by weight, the above effect is difficult to obtain, and if it is more than 10 parts by weight, bubbles and the like increase and handling becomes difficult.

The higher fatty acid will be specifically described below.
For example, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, ricinoleic acid, linoleic acid, linolenic acid, eleostearic acid, arachidic acid, arachidonic acid, behenic acid, erucic acid, abietic acid. , Rosin acid, coconut oil, linseed oil, beef oil, tall fatty acid, phytic acid and the like.

The higher fatty acid esters include the above-mentioned higher fatty acids and hydroxy compounds, for example, alcohols such as methyl alcohol, ethyl alcohol, propyl alcohol and butyl alcohol, ethylene glycol, glycerin, pentaerythritol, sorbitol, diethylene glycol, dipropylene glycol and the like. Ester compounds with polyhydric alcohols are preferred.

The higher fatty acid and / or higher fatty acid ester has a function of aggregating the deinked printing material and preventing it from re-adhering to the recording medium. The amount added in the entire deinking solution is 5 to 95
It is used in an amount of 20% by weight, preferably 20 to 80% by weight. If it is less than 5% by weight, the cohesive effect is lowered, and if it is more than 95% by weight, the effect of the liquid for dissolving or swelling the printing material is lowered.

Water is mentioned as a component that swells the fibers of paper, which is one of the recording materials, and makes the printing material easily detach from the paper fibers. The amount of water added to the entire deinking solution is 1 to 90% by weight, preferably 30 to 80% by weight based on the entire deinking solution. 90% by weight of water used
If it exceeds, the fibers of the paper will be destroyed, and the drying after deinking will take too much labor, which is not preferable. If the amount of water used is less than 1% by weight, the effect of spreading the fibers of the paper cannot be obtained, and the deinking agent cannot properly permeate into the paper. An appropriate amount is set according to the type of liquid that dissolves or swells the resin.

As a component that enhances the penetrability of the deinking liquid into the printing material and the paper and contributes to shortening the deinking time, for example, an organic acid can be mentioned. Specifically, saturated aliphatic carboxylic acids such as formic acid, acetic acid, propionic acid, butyric acid, valeric acid,
Pymic acid, caproic acid, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, etc., unsaturated aliphatic carboxylic acids such as acrylic acid, propiolic acid, methacrylic acid, crotonic acid, oleic acid, lenolic acid , Erucic acid, ricinoleic acid, abietic acid, rosin acid, or aromatic carboxylic acids such as benzoic acid, toluic acid, naphthoic acid, cinnamic acid, 2-furic acid, nicotinic acid and isonicotinic acid can be used. . These organic acids can be used alone or in admixture of two or more. Of these, higher fatty acids such as lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, linoleic acid, erucic acid, ricinoleic acid, abietic acid and rosin acid are preferred. Palm oil, linseed oil, beef tallow, whale oil and the like containing these higher fatty acids can also be used.

It is desirable that the organic acid is contained in the deinking agent in an amount of 1 to 10% by weight. Although the function of the organic acid used in the present invention in the deinking action is not always clear, the deinking agent of the present invention improves penetration into toner, paper, etc., shortens deinking time, and removes efficiently. It is thought to have an effect.

To the deinking agent of the present invention, for example, methanol, ethanol, n-butanol, isopropanol, ethoxyethanol, etc. may be added within a range that does not impair the effects of the present invention.

As a compounding form of each component for performing deinking easily and efficiently, (divalent organic acid monoester, organic acid, surfactant, water), (glycol ether solvent, higher fatty acid and / Or higher fatty acid ester, surfactant, water), (organic solvent, surfactant, water) and the like can be exemplified, but needless to say, the combination is not limited to these.
