Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an image forming substance removing apparatus, and more particularly to an image forming substance removing apparatus that reliably removes an image forming substance from an image carrier and regenerates the image carrier in a reusable state.
[0002]
[Prior art]
With the recent shift to OA (Office Automation), information is recorded on recording paper by printers, copiers, etc., and a large amount of paper such as printer paper and copying paper on which this information is recorded is generated in the office. However, at present, many of the papers are wasted.
[0003]
When paper with these information recorded is disposed of, it costs a lot of money, and it also leads to a deterioration of the local environment due to the disposal, and thus a global environmental deterioration due to deforestation for paper production. .
[0004]
Conventionally, in order to solve this problem and to recycle the paper, the ink used on the paper once used is removed, soaked again, and retreated, thereby being used as recycled waste paper.
[0005]
This waste paper recycling process requires a large-scale waste paper recycling facility and has to go through a number of processes to obtain used paper for sorting, collection, transportation, etc. .
[0006]
Therefore, recently, paper has been developed that can remove a character image on paper once used by cleaning and reuse it for copying or printing. For example, in JP-A-1-101576, an image forming support (paper) on which an image is formed with an image forming substance (toner) is subjected to ultrasonic treatment in an organic solvent that dissolves the image forming substance. An imaging material removal method is disclosed in which the imaging material is removed from the imaging support.
[0007]
In addition, the toner is dissolved by dipping, spraying, or applying a solvent to the printed part of the waste paper to dissolve the toner, and the dissolved toner is removed by a method such as washing, air suction, adsorbent contact, mechanical peeling, or electrostatic adsorption. An image forming substance removing method has been proposed (see Japanese Patent Laid-Open No. 4-300395).
[0008]
In addition, the applicant previously includes, in the recorded image carrier, water as a destabilizing liquid, an aqueous solution containing a surfactant, an aqueous solution containing a water-soluble polymer, and a surfactant and a water-soluble polymer. Proposed a method of removing an image forming substance that holds at least one kind of water or an aqueous solution from an aqueous solution, interposes a peeling member, and peels the image forming substance from the image carrier by heat bonding or pressure bonding to the peeling member. (See JP-A-7-84396).
[0009]
According to these, only the image forming substance can be removed from the image carrier without relatively damaging the paper quality of the image carrier.
[0010]
In addition, as a pretreatment of the means for removing and peeling off the image forming substance, the present applicant reduces the fixing power of the image forming substance to the image carrier and facilitates peeling of the image forming substance from the image carrier. In the image forming substance removing apparatus that transfers and removes the image forming substance to the peeling member after applying the apparatus having the above means and the image removal accelerating liquid, prior to the application of the liquid, partial removal of the image forming substance and image formation The microscopic gap in the image made of the material is enlarged, or the image made of the image forming material is damaged or destroyed, so that the image removal accelerating liquid is efficiently applied between the image forming material and the image carrier. An image forming substance removing apparatus having means for invading the interface has been proposed (see Japanese Patent Application Laid-Open Nos. 7-20754 and 7-175255).
[0011]
Further, in an apparatus for removing an image forming substance on an image carrier using an image removal accelerating liquid, at least one silicone-based surfactant is used to improve reproduction failure caused by silicone during copy fixing. Has been proposed (see JP-A-7-234535).
[0012]
According to this, the affinity between the silicone, and thus the toner with silicone adhered, and the image removal accelerating liquid is improved, and the repelling between the toner and the image removal accelerating liquid is less likely to occur. The adhesion force with the image forming substance can be efficiently reduced, and the ability to remove the image forming substance can be improved.
[0013]
[Problems to be solved by the invention]
However, those described in the above publications still have room for improvement in removing the image forming substance from the image carrier efficiently and reliably.
[0014]
That is, in the method for removing an image described in JP-A-1-101576, since an organic solvent is used, there is a new problem that pollution due to the organic solvent is generated. However, there was still a problem in using it in general offices and homes, as it required careful handling.
[0015]
In addition, in the image forming substance removal method described in JP-A-4-3000039, the toner is dissolved, and the dissolved toner is removed by a method such as washing, air suction, adsorbent contact, mechanical peeling, or electrostatic adsorption. Therefore, there is a problem that the image forming substance removing apparatus becomes large and expensive.
[0016]
Further, in the image forming substance removing method described in JP-A-7-84396 and the image forming substance removing apparatus described in JP-A-7-20754 and JP-A-7-175255 filed earlier by the present applicant. Remove the image forming material by applying an image removing substance or applying an image removal accelerating liquid, and then bringing the peeling member into contact with the surface of the image carrier on which the image forming substance is fixed. Since the image forming substance has been removed, an inhibitory substance that reduces the adhesion between the peeling member and the image forming substance on the surface of the image holding member on the surface of the image forming substance, such as dust, dust, silicone or oil If an oil component such as is attached, the adhesion between the peeling member and the image forming substance is hindered by this inhibitor, and the image forming substance on the image carrier is removed efficiently and reliably by the peeling member. Difficult to do.
[0017]
That is, as shown in FIG. 12, when the image forming substance 2 is fixed to the surface of the transfer paper 1 that is an image carrier to form a fixed image, dust, dust, silicone, oil or the like is formed on the surface. When the inhibitory substance 3 such as the oil component is attached, the inhibitory substance 3 on the surface of the transfer paper 1 or the image forming substance 2 inhibits the adhesion between the peeling member 4 and the image forming substance 2, and the image forming substance 2 It is difficult to remove the toner from the transfer paper 1 by attaching it to the peeling member 4, and there is room for improvement in improving the image forming substance removal performance.
[0018]
In view of this, the invention according to claim 1 is characterized in that the image-forming substance is provided on the surface of the image carrier on which a film-like fixed image is formed with a thermoplastic or heat-meltable image-forming substance. And pressurizing and heating in a state where a peeling member having an adhesive strength stronger than that of the image holding member is in contact with the image holding member, separating the peeling member and the image holding member, and removing the image forming substance. In an image forming substance removing apparatus that removes the image forming substance from the image holding member by attaching to the member, the peeling member and at least the surface of the image forming substance are contacted with each other before the image holding body and the peeling member are brought into contact with each other. As an inhibitor removal means for removing an inhibitor that inhibits adhesion with the image forming substance, an adhesive roller that removes the inhibitor while adhering to and rotating while in contact with the image carrier is provided. Statue It is possible to remove the image-forming substance from the image carrier more reliably and reliably at a lower temperature by properly attaching the substance and efficiently removing the image-forming substance from the image carrier. By using an adhesive roller that rotates in contact with the image carrier and removes the inhibitory substance as a removing means, the inhibitory substance can be removed from the surface of the image carrier and the image forming substance with a simple structure at a lower cost. An image forming substance removing apparatus capable of efficiently removing an image forming substance from an image carrier and removing the image forming substance from the image carrier more reliably at a lower temperature. It is an object.
[0019]
According to a second aspect of the present invention, the adhesive roller removes the inhibitory substance containing an oil component that inhibits the adhesion between the peeling member and the image forming substance, so that the surface of the image carrier or the image forming substance is removed. Even when an inhibitory substance containing an oil component is attached, the inhibitory substance containing the oil component is removed before attaching the peeling member to the image carrier, and the peeling member and the image forming substance are properly attached, An object of the present invention is to provide an image forming substance removing apparatus capable of efficiently removing an image forming substance from an image carrier and removing the image forming substance from the image carrier more reliably at a lower temperature. It is said.
[0020]
[Means for Solving the Problems]
The image forming substance removing apparatus according to the first aspect of the present invention is the image forming substance on the surface of the image carrier on which the film-like fixed image is formed with the predetermined image forming substance. On the other hand, after pressing or heating in a state where a predetermined peeling member having an adhesive strength stronger than that of the image carrier is in contact, the peeling member and the image carrier are separated, and the image-forming substance is separated from the image carrier. In an image forming substance removing apparatus that removes the image forming substance from the image holding member by attaching to the peeling member, the peeling member and the peeling member from at least the surface of the image forming substance before contacting the image holding body and the peeling member. The object is achieved by providing an inhibitor removing means for removing the inhibitor that inhibits the adhesion of the image forming substance.
[0021]
According to the above configuration, at least the image is removed by the inhibitor removing means before the peeling member is brought into contact with the surface of the image carrier on which the film-like fixed image is formed by the image forming substance. After removing the inhibitor that inhibits the adhesion between the peeling member and the image forming substance from the surface of the forming material, and then pressing or heating in a state where the peeling member is in contact, the peeling member and the image carrier are separated. Since the image forming substance is attached to the peeling member to remove the image forming substance from the image holding body, the peeling member and the image forming substance are appropriately attached to efficiently remove the image forming substance from the image holding body. The image forming substance can be removed from the image carrier more reliably at a lower temperature.
[0022]
Further, according to the above configuration, since the adhesive roller that rotates in contact with the image carrier and removes the inhibitor is removed as the inhibitor removal means, the surface of the image carrier can be reduced more easily with a simple configuration. Inhibitors can be removed from the surface of the image forming material, and the image forming material can be efficiently removed from the image carrier to remove the image forming material from the image carrier more reliably at a lower temperature. can do.
[0023]
In this case, for example, as described in claim 2, the inhibitory substance includes an oil component that inhibits adhesion of the peeling member and the image forming substance, and the inhibitory substance removing unit includes the oil component. An inhibitor may be removed.
[0024]
According to the above configuration, when the inhibitor contains an oil component that inhibits adhesion between the peeling member and the image forming substance, the inhibitor containing means removes the inhibitor containing the oil component by the inhibitor removal means. Even when an inhibitor containing an oil component adheres to the surface of the holding body or the image forming substance, the inhibitor containing the oil component is removed before attaching the peeling member to the image holding body. The image-forming substance can be appropriately attached, and the image-forming substance can be efficiently removed from the image carrier to remove the image-forming substance from the image carrier more reliably at a lower temperature. it can.
[0025]
Further, for example, the inhibitor removal means may contact the image forming substance to transfer and remove the inhibitor from the image carrier, and the transfer removing member may be in contact with the image forming substance by heating. And a contact member to be brought into pressure contact.
[0026]
According to the above configuration, as the inhibitor removal means, the transfer removal member that contacts and removes the inhibitory substance from the image holding member in contact with the image forming substance, and the transfer removal member is brought into thermal contact or pressure contact with the image forming substance. And the contact member, the inhibitory substance that cannot be removed at low temperature can be appropriately removed, the image forming substance can be efficiently removed from the image carrier, at a lower temperature, and The image forming substance can be more reliably removed from the image carrier.
[0027]
Further, for example, the inhibitor removing unit may be a blade that contacts the image carrier and scrapes and removes the inhibitor from the image carrier.
[0028]
According to the above configuration, the inhibitor is removed from the image carrier by scraping and removing the inhibitor from the image carrier as the inhibitor removal means. The inhibitor can be efficiently removed from the image-forming substance and the image carrier with a simple structure, and the image-forming substance can be efficiently removed from the image carrier at a lower temperature, and Thus, the image forming substance can be removed from the image carrier more reliably and inexpensively.
[0029]
Further, for example, the inhibitor removing unit may be a brush that contacts the image carrier and sweeps away the inhibitor from the image carrier.
[0030]
According to the above configuration, the inhibitor removal means removes the inhibitor without damaging the image carrier because the brush that contacts the image carrier and sweeps away the inhibitor from the image carrier is used. The image forming substance can be efficiently removed from the image carrier with a simple configuration. Therefore, it is possible to remove the image forming substance from the image carrier at a lower temperature and more reliably at a lower cost.
[0031]
Further, for example, the inhibitor removing unit may be a wiping member that contacts the image carrier and wipes and removes the inhibitor from the image carrier.
[0032]
According to the above configuration, since the wiping member that contacts the image carrier and wipes and removes the inhibitor from the image carrier is used as the inhibitor removal means, the surface of the image carrier and the image forming substance are uniformly distributed. The inhibitory substance can be removed, and the image forming substance can be reliably removed from the image carrier. Therefore, the image forming substance can be removed from the image carrier more reliably at a lower temperature.
[0033]
Further, for example, the inhibitor removing means may include a predetermined removal liquid for removing the inhibitor from the image carrier in the wiping member.
[0034]
According to the above configuration, as the inhibitor removal means, the wiping member contains a predetermined removal liquid for removing the inhibitor from the image carrier, so that the inhibitor is physically removed. In addition, an inhibitory substance that is difficult to remove physically and reliably, such as an oil component, can be chemically removed reliably, and an image forming substance can be more reliably removed from the image carrier. Therefore, the image forming substance can be removed from the image carrier more reliably at a lower temperature.
[0035]
Further, for example, the inhibitor removing unit may be a removing liquid applying unit that applies a predetermined removing solution for removing the inhibitor from the image holding member to the image holding member.
[0036]
According to the above configuration, as the inhibitor removal means, the removal liquid applying means for applying the predetermined removal liquid for removing the inhibitor from the image carrier is used as the inhibitor removal means. Inhibitors that are difficult to remove reliably can be removed chemically, and the image-forming substance can be efficiently removed from the image carrier, at a lower temperature and more reliably from the image carrier. The imaging material can be removed.

However, the scope of the present invention is particularly limited in the following description. As long as there is no description which limits, it is not restricted to these aspects.
[0038]
1 to 4 are diagrams showing an image forming substance removing apparatus to which the first embodiment of the image forming substance removing apparatus of the present invention is applied. In the present embodiment, image formation is performed by an electrophotographic copying machine or the like. After the inhibitory substance is removed from the surface of the image carrier, such as paper (transfer paper), by an adhesive roller, the image forming substance is peeled and removed, and applied to an image forming substance removing apparatus for reproduction.
[0039]
FIG. 1 is an overall configuration diagram of an image forming substance removing apparatus 10, and the image forming substance removing apparatus 10 includes a paper feeding unit U1, an inhibitor removing unit U2, a liquid applying unit U3, a peeling / moving unit U4, and a drying unit U5. And a paper receiving unit U6 and the like. The peeling / moving unit U4 is provided with a cleaning unit 11 for removing the removed image forming substance from the peeling member.
[0040]
The image forming substance removing apparatus 10 feeds transfer sheets 105 (see FIG. 2) to be reproduced one by one from the sheet feeding unit U1 to the inhibiting substance removing unit U2, and the inhibiting substance removing unit U2 supplies the transfer sheet 105 onto the transferring sheet 105. Inhibitors are removed and fed to the liquid application unit U3. After the image application liquid is applied to the transfer paper 105 by the liquid application unit U3, image formation on the transfer paper 105 is performed by the separation / movement unit U4. The material is peeled and removed, and the transfer paper 105 from which the image forming material has been peeled and removed by the drying unit U5 is dried and placed on the paper receiving unit U6.
[0041]
Specifically, the image forming substance removing apparatus 10 is configured as shown in FIG. 2, and the units U1 to U6 will be sequentially described below. The paper feed unit U1 includes a paper feed case 101, a paper feed roller 102, a pair of registration rollers 103, a guide plate 104, and the like. In the paper feed case 101, transfer paper as an image carrier to be reproduced is provided. A plurality of 105 are stored.
[0042]
Although not shown, the paper feed case 101 includes a bottom plate on which the transfer paper 105 is placed. The bottom plate is urged upward by a spring or the like (not shown) so that the inside of the paper feed case 101 is provided. The end of the transfer paper 105 on the paper feed roller 102 side is lifted upward. The paper feed roller 102 is rotationally driven at a predetermined timing by a drive motor or the like (not shown), and sequentially transfers the transfer paper 105 in the paper feed case 101 from the uppermost transfer paper 105.
[0043]

Paper is fed to the inhibitor removal unit U2 via 104.
[0044]
The transfer paper 105 as the image carrier is mainly composed of a swelling layer that is swollen by an image removal accelerating liquid 312 containing water at least near the surface on the image forming side, for example, a polysaccharide natural polymer such as cellulose fiber. It is a normal copying paper or printing paper. The image carrier is not limited to those described above. For example, if an image carrier capable of forming an image in which a paper layer such as cellulose fiber is provided on a sheet-like member, all are paper layers. It may not be, and it is not restricted to what contains paper and a paper quality layer, For example, films, such as OHP, may be sufficient.
[0045]
In addition, an image is formed on the transfer paper 105 by an electrophotographic method using dry toner or wet toner. However, the image forming method is not limited to this. For example, a hot-melt ink sheet is used. It may be formed by the thermal transfer method used, the ink jet method using hot melt ink, or the printing method using an offset plate, intaglio plate, letterpress plate or stencil. In short, as shown in FIG. 105) Any image forming method may be used as long as it forms a film-like image made of the thermoplastic or heat-meltable image forming material 20.
[0046]
The film form does not necessarily require that the entire image forms a single film, but simply means that the image forming substance does not penetrate inside the image carrier, or when printing with aqueous ink containing a dye. As described above, this means that the image forming substance is not almost adsorbed on the image carrier at the molecular level, and it means that the image forming substance is formed of a thermoplastic or heat-meltable image forming substance 20.
[0047]
As the thermoplastic or heat-meltable image-forming substance 20, specifically, a material containing at least one of the above-listed materials such as polystyrene and polyalkyl acrylate can be used.

For example, in an electrophotographic system, a charge control agent is contained, and in thermal transfer ink, various waxes are added as a vehicle and rosin (abietic acid) derivative is added as an adhesive. It is done.
[0050]
The inhibitor substance removing unit (inhibitor substance removing means) U2 is configured as shown in FIG. 3, and an adhesive roller 203 is disposed between the conveying roller pair 201 and the conveying roller pair 202, and a paper feeding unit. The transfer paper 105 sent out from U1 is conveyed in the direction of the arrow in FIG. 3 by the conveyance roller pair 201 and the conveyance roller pair 202, and the image is fixed on the transfer paper 105, in particular, the transfer paper 105 by the adhesive roller 203. The inhibitory substance 21 attached on the substance 20 is attached to the adhesive roller 203 to remove the inhibitory substance 21 from the image forming substance 20. Although not shown, the transfer paper 105 is pressed toward the adhesive roller 203 by a backup member that conveys the transfer paper 105 while pressing the transfer paper 105 against the adhesive roller 203. An urging pressure roller or the like may be provided.
[0051]
The inhibitory substance 21 attached to the adhesive roller 203 and removed from the image forming substance 20 is removed from the adhesive roller 203 by the cleaning mechanism 204. The cleaning mechanism 204 includes, for example, a blade 205 and an inhibitor receiver 206, and the blade 205 scrapes the inhibitor 21 from the adhesive roller 203 to clean the adhesive roller 203, thereby inhibiting the scraped inhibitor 21. Collect in the material receiver 206. Note that the cleaning mechanism 204 is not limited to the one having the above-described configuration, and for example, the surface of the adhesive roller 203 may be wiped with a nonwoven fabric containing water. Further, the inhibitor 21 can be removed from a certain number of transfer sheets 105 without providing the cleaning mechanism 204.
[0052]
The adhesive roller 203 is adhesive enough to transfer and remove the inhibitory substance 21 on the image forming material 20 without peeling off the fibers on the surface of the transfer paper 105, for example, the adhesive force between the image forming material 20 and the transfer paper 105. A material that is weaker by a predetermined amount than the adhesive force between the image-forming substance 20 and the inhibitory substance 21 and that is stronger by a predetermined amount is used. As such an adhesive roller 203, for example, a cleaning adhesive roller made of butyl rubber or the like can be used.
[0053]
In FIG. 3, the lower side of the transfer paper 105 is an image forming surface, and the inhibitor 21 adhering to the image forming surface is shown to be removed by the adhesive roller 203. The configuration for removing the substance 21 is not limited to this, and for example, two adhesive rollers 203 may be provided to remove the inhibitory substance 21 on both sides of the transfer paper 105. The inhibitor 21 can be removed from both sides of the transfer paper 105 on which the image is formed at a time.
[0054]
The inhibitor removal unit U2 transports the transfer paper 105, from which the inhibitor 21 has been removed by the adhesive roller 203, to the liquid application unit U3 by the transport roller 202.
[0055]
As shown in FIG. 2, the liquid applying unit U3 includes a replenishing liquid container 301, a liquid automatic replenishing machine 302, a liquid container 303, a liquid scooping roller 304, a liquid applying roller 305, a pressing roller 306, a conveying belt 307, a driving roller 308, A guide plate 309 and the like are provided, and the replenishing liquid container 301 and the automatic liquid replenishing machine 302, and the automatic liquid replenishing machine 302 and the liquid container 303 are connected by pipes 310 and 311, respectively.

[0058]
The liquid pumping roller 304 and the liquid application roller 305 are rotationally driven while abutting at a predetermined pressure, and the liquid pumping roller 304 is rotationally driven to pump and contact the image removal promoting liquid 312 in the liquid container 303. A predetermined amount of the image removal accelerating liquid 312 is attached to the liquid application roller 305 by being squeezed by the liquid application roller 305. The liquid application roller 305 applies a small amount of the adhering predetermined amount of the image removal accelerating liquid 312 to the image forming surface of the transfer paper 105 that has been fed from the inhibitor removal unit U2 between the pressure roller 306 and the image. The transfer paper 105 coated with the removal accelerating liquid 312 is fed to the peeling / moving unit U4 by the conveying belt 307 driven by the driving roller 308 while being guided by the guide plate 309.

For example, two liquid application rollers 305 may be provided to apply the image removal accelerating liquid 312 to both surfaces of the transfer paper 105. In this case, the images on both sides of the transfer paper 105 having images formed on both sides can be removed at once. Further, the liquid application roller 305 is not in contact with the transfer paper 105 and applied, but the image removal promoting liquid 312 is applied in a non-contact manner, or the liquid application roller 305 and the non-contact application means are combined in two steps. May be applied.
[0060]
When the image removal accelerating liquid 312 is applied to the transfer paper 105 on the side where the image is formed, the transfer paper 105 to which the image removal accelerating liquid 312 is applied is conveyed to the peeling / moving unit U4.

While the transfer paper 105 to which the image removal accelerating liquid 312 is applied is conveyed to the peeling / moving unit U4, as described above, the adhesive force between the transfer paper 105 and the image forming material 20 due to the swelling of the transfer paper 105. Is weakened.
[0076]
The peeling / moving unit U4 includes a plurality of peeling rollers 401a to 401e and peeling rollers 402a to 402d, a plurality of conveying rollers 403a to 403e and conveying rollers 404a to 404d, two peeling belts (peeling members) 405a and 405b, and a cleaning unit. 11, two spiral rollers 406a and 406b, an image forming substance receiver 407, a pair of delivery rollers 408, a conveyance belt 409, a conveyance roller 410, and the like.
[0077]
The plurality of peeling rollers 401a to 401e and the peeling rollers 402a to 402d are in contact with each other and are arranged in a zigzag shape so as to sew between the peeling rollers 401a to 401e and the peeling rollers 402a to 402d in a zigzag manner. The two peeled belts 405a and 405b are wound around. The peeling rollers 401a to 401e are arranged below the peeling belts 405a and 405b, and the peeling rollers 402a to 402d are arranged above the peeling belts 405a and 405b. The peeling belts 401a to 401e and the peeling rollers 402a to 402d are arranged so that the lower ends thereof intersect with each other, and the peeling rollers 401a to 401e are rotationally driven by a driving mechanism (not shown) so as to be closely integrated. 405a and 405b are conveyed and moved from left to right in FIG. 2 in a zigzag manner. The peeling rollers 402a to 402d may be rotationally driven by a driving mechanism (not shown) so that the peeling rollers 401a to 401e are suspended. Both the peeling rollers 401a to 401e and the peeling rollers 402a to 402d are not shown. The drive mechanism may be rotationally driven.
[0078]
The peeling belt 405a is formed in a ring shape having a predetermined width, for example, a width sufficient to hold the transfer paper 105 of various sizes and peel and transfer the image forming material 20 on the transfer paper 105. Then, it is guided by the conveying rollers 403a to 403e and supplied to the zigzag conveying path composed of the peeling rollers 401a to 401e and the peeling rollers 402a to 402d.
[0079]
The peeling belt 405b is formed in a ring shape having the same width as that of the peeling belt 405a, is guided by the conveyance rollers 404a to 404d, and is supplied to the zigzag conveyance path.
[0080]
Accordingly, the peeling belt 405a and the peeling belt 405b are brought into close contact with each other and moved along the zigzag conveyance path.
[0081]
Each of the peeling rollers 401a to 401e includes heating lamps 411a to 411e. The heating lamps 411a to 411e are energized from a power source (not shown) and are energized and controlled by a power supply control unit (not shown). 401a to 401e are heated to a predetermined temperature.
[0082]
Each of the peeling rollers 402a to 402d has a built-in heating lamp 412a to 412d. The heating lamps 412a to 412d are energized from a power source (not shown) and are energized and controlled by an energization control unit (not shown). The rollers 402a to 402d are heated to a predetermined temperature.
[0083]
The heating temperature of the peeling rollers 401 a to 401 e by the heating lamps 411 a to 411 e and the heating temperature of the peeling rollers 402 a to 402 d by the heating lamps 412 a to 412 d depend on the physical properties of the image forming substance 20, but the image forming substance 20 on the transfer paper 105. It is desirable to carry out to such an extent that does not melt. That is, the heating rollers 411a to 411e and the heating lamps 412a to 412d heat the peeling rollers 401a to 401e and the peeling rollers 402a to 402d by softening the image forming substance 20 fixed to the transfer paper 105 by heating, This is to make it easy to peel off from the transfer paper 105. When the image forming substance 20 is melted, the image forming substance 20 on the transfer paper 105 is peeled off without being divided into the transfer paper 105 side and the peeling belts 405a and 405b. This is because it is difficult to transfer to the belts 405a and 405b. Further, if the peeling rollers 401a to 401e and the peeling rollers 402a to 402d are heated too much, the transfer paper 105 dries too much while passing through the peeling / moving unit U4, and the transfer paper 105 passes through the image forming substance 20 and the peeling belt. It may stick to 405a and 405b and cannot be separated. Therefore, it is desirable to heat the transfer paper 105 that has passed through the peeling / moving unit U4 so that some moisture remains and the image forming substance 20 can be prevented from reattaching to the transfer paper 105.
[0084]
The peeling belts 405a and 405b are members for peeling and transferring the image forming material 20 from the transfer paper 105 by adhering to the image forming material 20 on the transfer paper 105, which is an image carrier, and the peeling belts 405a and 405b. As the material constituting the image forming material 20, it has an adhesiveness larger than the adhesive force between the surface of the transfer paper 105 and the image forming material 20 with respect to the image forming material 20, and also needs to have heat resistance when heated. is there.
[0085]
Examples of the release belts 405a and 405b include synthetic rubbers such as isoprene rubber, neoprene rubber, clooprene rubber, silicon rubber, butadiene rubber, and fluorine rubber, natural rubber, epoxy resins such as bisphenol / epichlorohydrin condensate, alkyd resins, and urea formaldehyde.

[0086]
Each of the above materials can be used alone, but in order to improve durability and peeling properties, etc., lamination, alloying, glass fiber, whiskers, carbon, silica, titanium oxide and other additions It can also be used in combination by adding an agent.
[0087]
The optimal material for the peeling belts 405a and 405b should be selected according to the type of the image forming substance 20 to be peeled off, the image forming substance removing process conditions, etc., but it is possible to reproduce the use of the peeling belts 405a and 405b repeatedly. This is advantageous in various respects such as lowering the cost. In that case, relatively high heat resistance and surface stability are required.
[0088]
Examples of release belts 405a and 405b that are preferable in terms of image removal characteristics and durability include polyethylene terephthalate, polyethylene naphthalate, polyetheretherketone, polyphenylene sulfide, polyparabalic acid, polyethernitrile, aramid, polyimide, polyetherimide, stainless steel. Examples include teal, nickel, and alumite.
[0089]
The cleaning unit 11 includes spiral rollers 406a and 406b and an image forming substance receiver 407. The spiral rollers 406a and 406b abut on the peeling belts 405a and 405b and rotate to transfer to the peeling belts 405a and 405b. The peeled image forming substance 20 is scraped off to clean the peeling belts 405a and 405b. An image forming substance receiver 407 is disposed below the spiral rollers 406a and 406b, and the image forming substance 20 scraped off by the spiral rollers 406a and 406b is stored in the image forming substance receiver 407.
[0090]
The transfer paper 105 to which the image removal accelerating liquid 312 is applied by the liquid application unit U3 and the adhesion between the image forming substance 20 and the transfer paper 105 is weakened is separated from the conveyance roller 403a and the conveyance roller 404a by the peeling belt 405a. It is inserted between the peeling belts 405b and is sandwiched between the peeling belts 405a and 405b.
[0091]
The transfer paper 105 on which the image forming material 20 is formed is sandwiched between the peeling belt 405a and the peeling belt 405b, and has a predetermined adhesion to the peeling belts 405a and 405b by the adhesive force of the peeling belts 405a and 405b. In a state of being bonded by force, the zigzag conveyance path is conveyed from left to right in FIG.
[0092]
Since the zigzag conveyance path is formed in a zigzag shape by the peeling rollers 401a to 401e and the peeling rollers 402a to 402d, the transfer paper 105 is passed through the zigzag conveyance path in a state where the transfer paper 105 is tightly and integrally held between the peeling belts 405a and 405b. While being conveyed, the transfer paper 105 and the peeling belts 405a and 405b are relatively displaced, and a shearing force is generated between the transfer paper 105 and the peeling belts 405a and 405b. The image forming material 20 is peeled off from the transfer paper 105 by this shearing force, peeled and transferred to the peeling belts 405a and 405b, and the transfer paper 105 from which the image forming material 20 has been removed is removed from between the transport rollers 403b and 404b. It is carried out to the delivery roller 408.
[0093]
While the transfer paper 105 sandwiched between the peeling belts 405a and 405b is being conveyed along the zigzag conveyance path, the heating lamps 411a to 411e and the heating lamp 412a incorporated in the peeling rollers 401a to 401e and the peeling rollers 402a to 402d. The image forming material 20 that forms an image on the transfer paper 105 is softened by being heated by ˜412d and is easily peeled off, and is efficiently transferred and removed to the peeling belts 405a and 405b.
[0094]
As described above, the transfer paper 105 from which the image forming substance 20 has been transferred and removed is conveyed to the delivery roller 408 from between the conveyance roller 403b and the conveyance roller 404b, and is delivered to the conveyance belt 409 by the delivery roller 408.
[0095]
The conveyance belt 409 is driven by a rotation-driven conveyance roller 410 and conveys the transfer paper 105 to the drying unit U5.
[0096]
Further, the image forming material 20 transferred to the peeling belts 405 a and 405 b is scraped off by the spiral rollers 406 a and 406 b and is stored in the image forming material receiver 407.
[0097]
In the above, the image forming substance 20 on both surfaces of the transfer paper 105 is simultaneously peeled and removed by the pair of peeling belts 405a and 405b. However, one of the peeling belts 405a and 405b, for example, the peeling belt 405b is peeled off. A seal member that holds the transfer paper 105 between the belt 405a and the belt 405a may be used. That is, when the image is formed on only one side of the transfer paper 105 or when the image is formed on both sides, the seal member is used to remove the image forming material 20 on each side. The sealing member is for tightly integrating with the peeling belt 405a to sandwich the transfer paper 105, and does not need to transfer the image forming material 20, and therefore the peeling belt 405a is not necessary except that it does not require adhesiveness. It is desirable to have the same characteristics as 405b.
[0098]
The drying unit U5 is for drying the transfer paper 105, and includes a drying drum 502, a finishing belt 503, rotating rollers 504a to 504d, and the like formed of aluminum or the like with a built-in heating lamp 501.

The other side is rotated by a motor or the like, and the other is suspended by a finishing belt 503. Note that both the drying drum 502 and the rotation rollers 504a to 504d may be rotationally driven by a drive motor or the like. The finishing belt 503 is made of a material having good air permeability, good heat resistance, and high surface smoothness, such as canvas, cotton, tetron, or woven fabric using aramid fibers. be able to.
[0100]
The transfer paper 105 conveyed from the peeling / moving unit U4 is introduced between the drying drum 502 and the finishing belt 503 between the drying drum 502 and the rotating roller 504a, and is heated by the heating drum 501 by the drying drum 502. Excess moisture is dried and discharged from between the drying drum 502 and the rotating roller 504d to the paper receiving unit U6.
[0101]
At this time, since the finishing belt 503 has good air permeability and its flat surface is formed of a highly smooth member, the transfer paper 105 is appropriately dried and the transfer paper 105 adheres to the finishing belt 503. The transfer paper 105 can be appropriately dried without being damaged or damaged.
[0102]
The drying unit U5 is not limited to the one having the above-described configuration. For example, instead of the above-mentioned configuration, or in addition to the above-described configuration, a roller pair member or hot air is used. Alternatively, a hot air fan or an infrared lamp may be used.
[0103]
The paper receiving unit U6 includes a guide member 601, a paper discharge tray 602, a discharge roller 603, and the like.
[0104]
The transfer paper 105 discharged from the drying unit U5 is guided to the discharge roller 603 by the guide member 601, and the discharge roller 603 discharges and places the transfer paper 105 on the paper discharge tray 602.
[0105]
Although not shown, the image forming substance removing apparatus 10 is a paper detection unit that detects whether or not the transfer paper 105 is in the paper supply case 101 of the paper supply unit U1, and multi-feed of the transfer paper 105 by the paper supply unit U1. Detection means, jam detection means for detecting the occurrence of jam in the image forming substance removing apparatus 10 on the transfer paper 105, lighting control means for each of the heating lamps 411a to 411e, heating lamps 412a to 412d and the heating lamp 501, and an image forming substance A full detection means for detecting whether or not the image forming substance 20 in the receiving container 407 is full is provided.
[0106]
Next, the operation of the image forming substance removing apparatus 10 will be described below. The image forming substance removing apparatus 10 removes the inhibitory substance 21 on the transfer paper 105 and then applies an image removal promoting liquid 312 to the transfer paper 105 so that the image forming substance 20 on the transfer paper 105 and the transfer paper 105 are transferred. With the adhesive force weakened, the transfer paper 105 is held between the peel belts 405a and 405b that are integrally adhered, and the zigzag transport path is zigzag transported by a predetermined amount, so that the relative displacement between the peel belts 405a and 405b and the transfer paper 105 is achieved. This is characterized in that the image forming substance 20 on the transfer paper 105 is peeled and removed in a small, efficient, and reliable manner by promoting the above.
[0107]
Hereinafter, the sequential operation of the image forming substance removing apparatus 10 will be described. When the image forming substance removing apparatus 10 is turned on and a plurality of transfer papers 105 on which fixed images are formed by the image forming substance 20 are placed on the paper feed case 101, the paper feeding is completed when a predetermined warm-up is completed. The transfer paper 105 in the paper supply case 101 is sequentially sent from the uppermost transfer paper 105 to the inhibitor removal unit U2 by the paper supply roller 102 of the unit U1. At this time, timing adjustment is performed by the registration roller pair 103.
[0108]
The transfer paper 105 is a normal copying paper or a printing paper, and the transfer paper 105 is an electrophotographic copying machine or a printing device using a normal dry toner or a wet toner. A film-like image is formed.
[0109]
As shown in FIG. 3, the inhibitor removal unit U <b> 2 applies to the adhesive roller 203 the inhibitor 21 adhered to the surface of the transfer paper 105 sent out from the paper feed unit U <b> 1, particularly the surface of the image forming substance 20. The transfer paper 105 that has been removed by adhesion and from which the inhibitor 21 has been removed is conveyed to the liquid application unit U3. The inhibitor removing unit U2 scrapes the inhibitor 21 adhering to and removed from the adhesive roller 203 with the blade 205 and stores it in the inhibitor receiver 206 to improve the inhibitor removal efficiency of the transfer paper 105 of the adhesive roller 203. ing.
[0110]
When the transfer paper 105 from which the inhibitor 21 has been removed from the inhibitor removal unit U2 is conveyed between the liquid application roller 305 and the pressure roller 306, the liquid application unit U3 supplies the replenishment liquid by the liquid automatic replenisher 302. The image removal promoting liquid 312 in the liquid container 303 pumped up from the container 301 is attached to the liquid application roller 305 by the liquid pumping roller 304 and is fed between the pressure roller 306 and the liquid application roller 305. A small amount is applied to the image forming surface of the transfer paper 105.
[0111]
The liquid applying unit U3 sends the transfer paper 105 coated with the image removal accelerating liquid 312 to the peeling / moving unit U4 by the transport belt 307.
[0112]
When the image removal accelerating liquid 312 is applied to the transfer paper 105, the vicinity of the surface of the transfer paper 105 swells, and due to the difference in swelling amount between the image forming material 20 and the transfer paper 105, there is a shear force between them. Occurs, and the adhesive force between the image forming substance 20 and the transfer paper 105 decreases. Further, it is considered that the shearing force between the image forming material 20 and the transfer paper 105 is particularly increased when the image removal accelerating liquid 312 penetrates to a portion as close as possible to the interface of the transfer paper 105 in contact with the image forming material 20. By allowing the image removal accelerating liquid 312 to permeate the interface where the transfer paper 105 and the image forming substance 20 are in contact with each other, even better removal characteristics of the image forming substance 20 can be obtained. Further, the penetration of the image removal accelerating liquid 312 to the interface where the transfer paper 105 and the image forming material 20 come into contact not only causes a shearing force due to a difference in swelling amount but also a component of the image removal accelerating liquid 312. In particular, when water or a surfactant is interposed between the image forming material 20 and the transfer paper 105, the adhesive force acting between the image forming material 20 and the transfer paper 105 is weakened. Conceivable.
[0113]
The transfer paper 105 to which the image removal accelerating liquid 312 is applied is peeled off in a state where the adhesive force between the image forming substance 20 and the transfer paper 105 is lowered while being conveyed to the peeling / moving unit U4 due to the swelling action. -It is conveyed to the moving unit U4.
[0114]
The peeling / moving unit U4 includes a plurality of peeling rollers 401a to 401e and peeling rollers 402a to 402d, and each of the peeling rollers 401a to 401e and the peeling roller is conveyed and moved in a zigzag manner by closely attaching and peeling the peeling belts 405a and 405b. 402a to 402d are heated to a predetermined temperature by the heating lamps 411a to 411e and the heating lamps 412a to 412d, and the transfer paper 105 that is sandwiched between the peeling belts 405a and 405b and the peeling belts 405a and 405b and is conveyed on the zigzag conveyance path is heated. .
[0115]
The transfer paper 105 in a state where the image removal accelerating liquid 312 is applied and the adhesive force with the image forming substance 20 is weakened is sandwiched between the peeling belt 405a and the peeling belt 405b, and the peeling belts 405a and 405b The zigzag conveying path is conveyed from the left to the right in FIG. 2 in a state in which it is adhered to the peeling belts 405a and 405b with a predetermined adhesive force.
[0116]
While the transfer paper 105 is transported through the zigzag transport path in a state where the transfer paper 105 is held tightly and integrally with the release belts 405a and 405b, the transfer paper 105 and the release belts 405a and 405b are relatively displaced, and the transfer paper 105 is peeled off. A shearing force is generated between the belts 405a and 405b. The image forming substance 20 is peeled off from the transfer paper 105 by this shearing force, and peeled and transferred to the peeling belts 405a and 405b.
[0117]
In addition, the transfer paper 105 sandwiched between the peeling belts 405a and 405b is heated while being conveyed through the zigzag conveyance path, and the heating lamps 411a to 411e incorporated in the separation rollers 401a to 401e and the separation rollers 402a to 402d and heating. Heated by the lamps 412a to 412d, the image forming material 20 forming an image on the transfer paper 105 is softened and easily peeled, and is efficiently transferred and removed to the peeling belts 405a and 405b.
[0118]
Further, as shown in FIG. 4, the transfer paper 105 conveyed to the peeling / moving unit U <b> 4 is inhibited by the inhibitor removal unit U <b> 2 on the surface of the transfer paper 105, particularly the inhibitor 21 on the image forming substance 20. Therefore, the adhesive force between the peeling belts 405a and 405b and the image forming material 20 is not hindered by the inhibitor 21 and the image forming material 20 is peeled off from the transfer paper 105 efficiently and reliably. The peeling belts 405a and 405b can be peeled and transferred.
[0119]
The transfer paper 105 from which the image forming material 20 has been transferred and removed as described above is sent to the drying unit U5 by the feed roller 408 and the conveying belt 409, and is also transferred to the peeling belts 405a and 405b. 20 is scraped off by the spiral rollers 406 a and 406 b and is stored in the image forming substance receiver 407.
[0120]
The drying unit U5 sandwiches the transfer paper 105 conveyed from the peeling / moving unit U4 between the drying drum 502 heated by the heating lamp 501 and the finishing belt 503, and then transfers the excess of the transfer paper 105. Fresh moisture is dried and discharged to the paper receiving unit U6.
[0121]
The paper receiving unit U6 discharges and places the transfer paper 105 discharged from the drying unit U5 on the paper discharge tray 602 by the discharge roller 603.
[0122]
As described above, the image forming substance removing apparatus 10 removes the inhibitor 21 adhering to the surface of the transfer paper 105 on which the image is formed by the image forming substance 20, in particular, the surface of the image forming substance 20, from the inhibitor removing unit U2. After the removal, the liquid application unit U3 applies the image removal accelerating liquid 312 so that the adhesion between the transfer paper 105 and the image forming substance 20 is weakened. The belts 405a and 405b are nipped and transported along the zigzag transport path to cause relative displacement between the peeling belts 405a and 405b and the transfer paper 105, and the image forming substance 20 is peeled from the transfer paper 105, and the peeling belt 405a. , 405b, the adhesion between the peeling belts 405a and 405b and the image forming substance 20 can be prevented from being inhibited by the inhibiting substance 21, and the image forming object can be prevented. 20 the release belt 405a, efficiently to 405 b, and can be reliably peeled off and transfer. Therefore, the peeling / removal performance of the inhibitor removal apparatus 10 can be further improved. In particular, since the inhibitory substance 21 is removed using the adhesive roller 203 in the inhibitory substance removal unit U2, the inhibitory substance 21 is removed from the surface of the transfer paper 105 and the surface of the image forming substance 20 at a lower cost with a simple configuration. In addition, the image forming substance 20 can be efficiently removed from the transfer paper 105, and the image forming substance 20 can be removed from the transfer paper 105 more reliably at a lower temperature.
[0123]
FIG. 5 is a diagram showing an image forming substance removing apparatus to which the second embodiment of the image forming substance removing apparatus of the present invention is applied.
[0124]
In the present embodiment, the inhibitor removal unit U2 of the first embodiment is changed to one that removes the inhibitor by heat-pressure adhesion. In the description of the present embodiment, the first The same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.
[0125]
In FIG. 5, an inhibitor removal unit (inhibitor removal means) U2A removes the adhesive roller 203 of the inhibitor removal unit U2 of the first embodiment, and heats and conveys rollers 701 and 702, a removal belt 703, and a cleaning. A heating lamp 705 and a heating lamp 706 are incorporated in the heating / conveying roller 701 and the heating / conveying roller 702.
[0126]
The heating lamp 705 and the heating lamp 706 are energized from a power supply (not shown), and the energization is controlled by a control circuit (not shown) to heat the heating conveyance roller 701 and the heating conveyance roller 702, and Heat. The heating temperature is desirably equal to or lower than the temperature at which the imaging substance 20 starts to flow out, that is, the temperature at which the measurement substance (imaging substance 20) starts to flow out in the Koka flow tester. That is, the image forming substance 20 is heated to a temperature higher than the outflow start temperature of the image forming substance 20, and the image forming substance 20 itself is melted and softened and deformed, so that it becomes difficult to remove the inhibitor 21.
[0127]
As the removal belt 703, the same resin film as the peeling belts 405a and 405b can be used.
[0128]
At least one of the heating and conveying roller 701 and the heating and conveying roller 702 is rotationally driven in a clockwise direction indicated by an arrow in FIG. 5 by a drive motor or the like, and conveys and rotates the removal belt 703 in the clockwise direction.
[0129]
According to the present embodiment, the heating conveyance rollers 701 and 702 are heated by the heating lamps 705 and 706 to heat the inhibitor 21 adhering to the surface of the transfer paper 105 sent out from the paper supply unit U1. Then, the inhibitory substance 21 is melted or the like to change the state or physical properties of the inhibitory substance 21, and the adhesive is removed from the removal belt 703. Therefore, by heating the inhibitor 21 that is difficult to remove from the transfer paper 105 at room temperature, the state and physical properties of the inhibitor 21 can be changed to make it easy to remove without using chemical means. The inhibitor 21 can be easily and reliably removed from the transfer paper 105.
[0130]
In particular, fixing oil such as silicone adheres as an inhibiting substance 21 to the transfer paper 105 formed with an image using a copying machine or the like using fixing oil such as silicone. The fixing oil such as silicone is peeled off. The adhesive force between the belts 405a and 405b and the image forming material 20 is reduced, and the peeling / removing ability of the image forming material 20 in the peeling / moving unit 4 is reduced. This phenomenon is particularly prominent in the transfer paper 105, such as an OHP film or coated paper, in which the oil component is less likely to penetrate inside and easily remains on the image surface.
