Efferent 3 uses roll webs, on band plate-like peeling paper S30, become row bonding the opaque sheet material S20 of white of a plurality of Len reqs, this opaque sheet material S20 becomes the inboard and is reeling like that.Form the adhesive linkage S20a that makes that clear sheet S10 is bonding at opaque sheet material S20 single face, the adhesive linkage S20a that is formed on this opaque sheet material S20 single face is bonding with the peel ply that is formed on the peeling paper S30.
The state that is provided with of roll web is described, as shown in Figure 5, roll web is arranged on the roll web bolster 32, by towards the counterclockwise revolution, export sheet material (constituting), among the sheet material of being pulled out with peeling paper S30 and opaque sheet material S20, only peeling paper S30 turns back at separating plate 34, the peeling paper S30 that this turns back is erected on the pony axle 33, by the revolution of winding off spindle 31 counterclockwises, makes peeling paper S30 be wound on the described winding off spindle 31.
The steering order of efferent 3 bases of roll web from the control part of image processing system B is set like this, winding off spindle 31 revolutions, from being arranged on the roll web output sheet material on the roll web bolster 32, turn back by separating plate 34 sheet materials, simultaneously, peel off opaque sheet material S20 from peeling paper S30, transport clear sheet S10 transporting portion 2, towards the carriage direction of this clear sheet S10, oblique output can be bonded on the clear sheet S10 in transit.In this example, transporting portion 2 and efferent 3, but transporting with making clear sheet S10 and opaque sheet material S20 oblique.On the other hand, the peeling paper S30 that peels off of opaque sheet material S20 batches and is recovered on the winding off spindle 31.
Separating plate 34 makes that opaque sheet material S20 and the formed angle of clear sheet S10 before the contact are initial position (angle), become and to suppress when opaque sheet material S20 contacts with clear sheet S10 to impact, can bonding reliably angle, after this, fix time variable.
Transport in the passage at the sheet material that connects second roller 22 and the 3rd roller 23, along carriage direction, a pair of crimping roller 4 is arranged on pivotally than opaque sheet material S20 and the clear sheet S10 intersection location position in downstream slightly, further bonding opaque sheet material S20 and the clear sheet S10 of pushing makes it bonding securely.
The sheet bonding device A that first example of above-mentioned formation relates to releasably is connected with image processing system B, carries out following a series of action.
Use the guidance panel of image processing system B etc. earlier, select to use the output mode of sheet bonding device A, beginning forms mirror image P on clear sheet S10.At this moment, the original image that is used to form image can be from being located at the image that does not have illustrated scanister to be taken at this image processing system B top, or the electronic image of delivering letters from electronic equipments such as computing machine or digital cameras.Clear sheet S10 being supplied with the supply mean of image processing system B can supply with from the paper feeding cassette that is located in the device, or manual supply etc., this is not particularly limited.
Then, handle toner picture (mirror image) transfer-fixing that small particle diameter polymerization toner is formed on clear sheet S10, connect paper with row's paper B22 of portion row from external device (ED) with known electrofax.At this moment, by the photographic fixing portion 68 in the image processing system B to external device (ED) connect clear sheet S10 with row's paper B22 of portion make record mirror image P image surface down, this clear sheet S10 down connects with row's paper B22 of portion by external device (ED), and 1a enters sheet bonding device A from the recording chart receiving port.
The portion that transports 2 that accepts clear sheet S10 transports clear sheet S10 towards the below.At this moment, according to steering order from the control part of image processing system B, in 31 revolutions of fixing time winding off spindle, from being arranged on the roll web output sheet material on the roll web bolster 32, by separating plate 34, peel off opaque sheet material S20 from peeling paper S30, oblique output makes itself and clear sheet S10 in transit overlapping.The travelling speed of clear sheet S10 is identical with the travelling speed of opaque sheet material S20.
The opaque sheet material S20 that begins to transport has bonding angle θ 0 as shown in Figure 5 and Figure 6, and it is by the initial position decision of configuration of transporting portion 2 and efferent 3 and separating plate 34, and is bonding with the preceding end in contact of clear sheet S10.Like this, the impact in the time of suppressing clear sheet S10 and opaque sheet material S20 and engage is at first guaranteed to begin bonding reliably.
Then, just begun bonding after, perhaps bonding from beginning, behind bonding institute measured length, according to the control signal from control part, the action of revolution solenoid is as Fig. 8 and shown in Figure 9, separating plate 34 is swung towards counterclockwise, pushing expansion sheet material (peeling paper S30 and opaque sheet material S20) with the angle according to its angle, is exported opaque sheet material S20, has bonding angle θ 1, bonding opaque sheet material S20 and clear sheet S10.Like this, by making the bonding angle θ 1 bigger, suppress bubble and enter than initial bonding angle θ 0.
Time as become bonding angle θ 1 from bonding angle θ 0, can be made as the moment that the bonding front end of adhesive sheet arrives a pair of crimping roller.Also comprise this occasion, following the example of of variable time can be by control times such as timers, perhaps use the impact conditions of sensor clear sheet S10 front end and opaque sheet material S20 front end, or whether the adhesive sheet front end has arrived a pair of crimping roller etc., obtain the time according to testing result, this is not particularly limited.
Like this, before clear sheet S10 rear end and opaque sheet material S20 rear end are overlapping, bonding both.In the meantime, after both are bonding, make both strong bond by a pair of crimping roller 4 at once.
Then, a pair of the 3rd roller 23 is passed through in clear sheet S10 rear end and opaque sheet material S20 rear end, both bonding end, and then separating plate 34 is got back to initial position, and winding off spindle 31 revolutions stop, and arrange paper to the row's paper portion that is located at bottom in the framework 1 as the image recording sheet material.If row's paper finishes, the action of transporting of transporting portion 2 stops, and begins to be in holding state before the bonding next time action.Finish a succession of action of the sheet bonding device A that first example relates to.
Speed when bonding angle θ 0 becomes bonding angle θ 1 is for exporting the needed speed of sheet material (peeling paper S30 and opaque sheet material S20) smoothly, but, also can become bonding angle θ 1 lentamente, become bonding angle θ 1 during to bonding end from bonding angle θ 0.
Concern about entering between bubble and the bonding angle, for example, the bonding angle occasion in the 10-45 degree left and right sides, impact in the time of suppressing both and contact, guarantee reliably bonding, in contrast, as shown in figure 10, because of the concavo-convex or sheet material on adhesive linkage S20a surface such as rocks slightly at reason, easily enter bubble C.If enter bubble slightly, then as shown in figure 11, diffuse reflection partly takes place in this bubble C, and is improper as the image recording sheet material.
In contrast, bonding angle for example surpasses 30 degree, and 90 degree are with interior occasion, is difficult to suppress to impact carry out bondingly, and if bonding, bubble is taken into and can reduces to seldom.In this example, by the action of separating plate 34, can become bonding angle θ 1 from bonding angle θ 0, can not produce bubble, can carry out bonding reliably.
And, clear sheet S10 rear end and opaque sheet material S20 rear end are by a pair of the 3rd roller 23, and both bonding end are arranged paper to the row's paper portion that is located at bottom in the framework 1 as the image recording sheet material, the action of transporting of transporting portion 2 stops, and begins to be in holding state before the bonding next time action.Finish a succession of action of the sheet bonding device A that first example relates to.
Like this, the sheet bonding device A that this example relates to is by separating plate 34 actions, make the clear sheet S10 of formation mirror image P and the bonding angle of opaque sheet material S20 become greatly bonding angle θ 1 from bonding angle θ 0, make that clear sheet S10 and opaque sheet material S20 are bonding, sandwich mirror image P.Like this, as shown in figure 12, can obtain the image recording sheet material that outward appearance becomes erect image with photograph image quality.Especially, by form the toner picture with small particle diameter polymerization toner, it is poor to reduce the height ladder that the toner image position causes, is difficult to gassing between clear sheet S10 and opaque sheet material S20, and can improve the texture of image itself, can obtain higher-quality image.
The illustrative clear sheet S10 of this example as shown in FIG. 13A, sheet material is region-wide to be transparent, still, also can be shown in Figure 13 B-13D, be the sheet material of part opaque (for example white).In Figure 13 B-13D, represent that with parallel oblique line the zone is an opaque section, other are transparent region.
The sheet bonding device A that this example relates to has been described above, but above-mentioned example only is an example, the present invention is not limited to above-mentioned example, can do all changes in the technology of the present invention thought range, and they all belong to protection scope of the present invention.
For example, in this example, when changing bonding angle, make separating plate 34 actions, but the present invention is not limited thereto, also can use controllable guide plate, push first sheet material or second sheet material and make it can be crooked, change transfer direction.The concrete structure of this occasion is identical with above-mentioned separating plate 34, because simple in structure, very suitable.
Have, the equipping position of also can stagger handover portion and efferent makes its variation again, to replace above-mentioned guide plate or separating plate 34.This occasion is preferably, and with handover portion and efferent blocking, makes unit self move.
In this example, on clear sheet S10, form mirror image P, make that for example the opaque sheet material S20 and the clear sheet S10 of white are bonding, still, also can on opaque sheet material S20, form image P, make that this opaque sheet material S20 and clear sheet S10 are bonding.
In this example, the sheet bonding device A of illustration and image processing system B connection, but the present invention is not limited to the output image recording sheet, also is suitable between the adhesive sheet.
In this example, illustration sheet bonding device A, but also can change a certain side in first sheet material and second sheet material, and perhaps change both sides' sheet material direction, make bonding angle change and carry out bonding sheet bonding method.In this occasion, the illustrative bonding angle θ 0 of above-mentioned example, bonding angle θ 1, the change time also is fit to.
Having, can be that bonding first sheet material and second sheet material sandwich the method that image P obtains the image recording sheet material again.Obtain this image recording sheet material method occasion, be preferably,, use small particle diameter polymerization toner, on clear sheet S10, form mirror image P as above-mentioned example illustration, the opaque sheet material S20 and the clear sheet S10 of for example white is bonding.

[the formation method of image web]
Below with reference to the formation method of Figure 16-Figure 18 explanation, has the New Year card occasion of gloss image in this explanation making as the image web of one of the invention process form.
Figure 16 is used to illustrate the bonding process of the bonding beginning of coating medium of image web formation method one example of the present invention, is recording medium and the cross section skeleton diagram that coats the configuration example of medium.
Recording medium S10 at least a portion has hyalomere S32, form relatively the colour original picture that constitutes by literal and/or artistic illustration etc. mirror image P as mirror image at the single face of this hyalomere S32, for example, form device by electrophotographic image, use toner to form image, perhaps form by image processing systems such as ink-jet recording apparatus.As required also relatively original image amplify or the downscaled images size.Also can form mirror image P through digital processing at hyalomere S32 single face to original digital image data.At this moment, be preferably, be considered to picture, make and the joggling part S38 of the coating medium that recording medium S10 is bonding is not configured on the mirror image of hyalomere of recording medium.
Then, prepare on matrix S37, to contain transparent or coloured adhesive layer S20a in addition, as nontransparent coating medium S20, pass through adhesive layer S20a from this leading section S35B that coats medium S20, so that coat the image P of recording medium S10, recording medium S10 and coating medium S20 can make image web S39 shown in Figure 17 by bonding integrated.
Adhesive layer S20a is located on the single face as the matrix S37 that coats a medium S20 part; can be in advance with processing release papers such as silicone resin film sheet; heat-resisting sheet material sticks on this adhesive layer S20a and protects, and when superimposed, peels off this processing release paper or heat-resisting sheet material with recording medium S10.As another kind of form, also can the hot cementing agent of usability, can be provided with as final operation and to invest portion, performance cohesiveness by heat.
Beyond the water white transparency occasion, adhesive layer S20a constitutes the background of finished figure picture.If this adhesive layer S20a water white transparency, then opaque S33 surface constitutes the background of finished figure picture.If opaque S33 be reflected in the finished product image background, can be so that adhesive layer S20a be transparent, if irrelevant, set the finished product image background with the look of opaque S33 or pattern etc., then can be so that adhesive layer S20a be white or other are coloured opaque.Cementing agent is look general standing white as a setting, and consideration can be corresponding with various images.
Figure 17 presentation video sheet material is the New Year card occasion, look to observe image web S39 shown in Figure 180 from hyalomere S32 sidelong glance as the image web S39 of New Year card, the image P that is configured in hyalomere S32 side is that the mirrored state with the mirror image P of the recording medium S10 of Figure 16 observes as erect image.The look of opaque the S33 of Figure 18, pattern etc. can be considered the transparent occasion of adhesive layer S20a, and are influential to the finished product image background, carry out appropriate designs.
In this example, especially as shown in figure 16, when bonding process, adhesive layer S20a is transparent or white or other are coloured, comprise this adhesive layer S20a, between the leading section S35B of opaque coating medium S20 and non-front end region S35A, angle θ is set, form joggling part S38.Angle θ is a benchmark with the matrix face that coats the non-front end region S35A of medium S20, angle warpage with less than 180 degree, especially, wherein, angle [alpha] is to the angle the bonding plane part of the rear end side surface level corresponding with recording medium S10 image surface from the joggling part S38 that coats medium S20, angle beta is the angle the surface level corresponding with recording medium S10 image surface of the bonding plane part from joggling part S38 to front, under the state of angle [alpha]＞angle beta, opening entry medium S10 and coating medium S20's is bonding, can prevent more effectively that bubble from taking place.In addition, angle θ is made as bigger acute angle and can prevents effectively when making that two media are bonding that also bubble from sneaking into.On the other hand, consider from reliably beginning bonding angle, can be so that the leading section S35B relative record medium S10 of coating medium S20 be parallel.
At least local recording medium S10 with hyalomere S32 contacts or the face contact from the leading section S35B relative record medium S10 surface line that coats medium S20 with the bonding process that coats medium S20, after this, by two media are clamped between the backer roll, by bonding becoming one.
In this example, during two medium bonding process, as shown in figure 16, warpage coats near the leading section S35B of medium S20 in advance, the face of matrix S37 with joggling part S38 as bifurcation, at the face that comprises leading section S35B with do not comprise the not enough angle θ of 180 degree are set between the face in leading section S35B zone, can prevent at no intention times two medium bondingly, can realize stable adhesion.In addition, by being made as, angle θ prevents effectively when bigger acute angle can prevent to make that by crimping roller two media are bonding more reliably that bubble from sneaking into.
At this, obtain the polymerization toner with small particle diameter and the narrow scope control of size-grade distribution, form mirror image P with this toner on recording medium S10 surface, can reduce non-image ladder poor (reducing the toner adhesion amount of image portion) with the intersection of image portion, can reduce bubble enters between recording medium and the coating medium, and image self texture is good, can obtain the more image of high image quality.
This example occasion, local at least transparent recording medium can the recording medium partially transparents, and also can one translucent half be opaque, also can be transparent fully.
In this example, image processing system for example can be handled automatically and be defined as transparent regional consistently, automatically the output image size is amplified or narrows down to suitable dimension, applies reverse turn operation as a succession of actions such as mirror images.With reference to Figure 19 embodiment is described.
Automatically carry out the image processing system of Fig. 3 and carry out image formation occasion, for example:
(1) user indicates the printing of implementation to transparent region, i.e. " printing of photograph image quality ".This indication can be by the setting button that for example duplicates, or the setting icon of the driver of printer is carried out.
(2) select image.
(3) printing indication (amplify suitably automatically or dwindle at transparent region, counter-rotating forms image).
The image of being carried out the hyalomere of image processing system by the program of the subsidiary control part that is provided with of image processing system forms, and the image that comprises the recording medium hyalomere forms, and is undertaken by step shown in Figure 19.
That is, print, then enter step S2, need to select the image of printing, indicate printing as if the image quality of selecting to take a picture step S1 user.At step S3, judge that whether the local at least recording medium with hyalomere is set at paper feeding cassette etc., if be not set up ("No" of step S3), then enters step S4, the expression error message.If be set up ("Yes" of step S3), then enter step S5, with the consistent size of hyalomere, amplify or dwindle the picture size that forms at hyalomere S32 shown in Figure 16, adjust.
At step S6, image data processing forms reverse image, so that form reverse image (mirror image) in the table at hyalomere S32.At step S7, adjust image beginning position, so that image is consistent with hyalomere S32.Then, at step S8, to image processing system indication printing output.At step S9, according to the printing purpose, carry out paper (recording medium) and transport, according to the resolution adjustment of printing indication, carry out image printing.
