The image processing system of this example also can be hoped image in the printshop on the common recording chart that is made up of paper wood etc. except first sheet material 100 that is made up of clear sheet, the light writing unit is set at mode standard, is printing erect image on the paper usually.Like this, select this mode standard occasion, make and switch pawl 18 actions, the recording chart that obtains photographic fixing at fixation unit 8 is sent to exit roller 20 through a pair of roller 19 that transports, and is discharged on the paper disc 21.This image processing system also is provided with printed on both sides mechanism; Sheet materials such as recording chart through fixation unit 8 transport passage in the 22 quilt switchings of switching pawl, and fortune is to a pair of reverse roll 23, after temporarily stopping; With a pair of reverse roll 23 contrary transporting; Through switching the switching of pawl 24, be sent to printed on both sides with transporting passage 25, supply with registration roller 17 once more.The sheet material of supplying with registration roller 17 is reversed to printing surface towards the outside, and the 7 transfer printing toner pictures in the secondary transfer printing unit by photographic fixing, are sent to a pair of transport roller 19 to be printed on recording chart two surface states at fixation unit 8.
Below, an example of the sheet bonding device (after-treatment device) that the present invention relates to reference to description of drawings.In the sheet bonding device 9 that this example shown in Figure 3 relates to; Use second sheet material 91; It is that white paper is made as base material 91a; On the one side of this base material 91a, form adhesive layer 91b, peeling paper 92 is bonded on this adhesive layer 91b, constitute second sheet material 91 (with reference to Fig. 6-Fig. 9) as non-transparent medium.
Feature structure of the present invention is, is provided with adhering part and tension force member of imparting 110A, 110B.Said adhering part comprises adhesive portion 103 and separated part; In above-mentioned adhesive portion 103, the first sheet material S1 that transports towards certain orientation relatively, the second sheet material S2 that makes single face be provided with adhesive layer 91b supplies with from non-parallel direction oblique; 91b is bonding through adhesive layer; The above-mentioned upstream side that is positioned at this adhesive portion 103, curvature is separated the peeling paper 92 on the adhesive layer that is stacked in the second sheet material S2, mentioned strain member of imparting 110A; 110B is positioned at the upstream side of separating plate (separated part) 93, gives the second sheet material S2 with tension force.
The front end time of contact of the second sheet material S2 that supplies with from tilted direction as the relative first sheet material S1, two sheet material travelling speeds are different, do not finish through adhesive layer is bonding, and in two sheet materials bonding finish times, second sheet material and first sheet material transport with constant speed.
Fig. 4 is near the sectional view in bonding position of the sheet bonding device of first example, and Fig. 5 is near the sectional view in bonding position that the sheet bonding device of tension force member of imparting was not set in the past.State when actual bonding non-transparent medium being described with reference to Fig. 4 and Fig. 5.
When winding off spindle 94 batches peeling paper 92; Fulcrum 90 is revolution simultaneously also, transports second sheet material (non-transparent medium) 91, as stated; Make the moment that winding off spindle 94 stops; Fulcrum 90 was not provided with in the sheet bonding device of tension force member of imparting in that kind shown in Figure 5 with the inertial force revolution in the past, and second sheet material 91 produces lax sometimes at 105 upper reaches, peeling paper separation point position.
If the 105Z upper reaches in the separation point position, second sheet material 91 and peeling paper 92 produces lax, second sheet material 91 that then leaves with separating plate 93Z; As shown in Figure 5; Receive lax influence, the separation angle when separating with peeling paper 92 has deviation, and bonding angle probably can produce deviation.Because of the bonding angle θ of first sheet material 100 and second sheet material 91, between first sheet material 100 and second sheet material 91, be prone to form bubble.This is learnt by inventor's research, in this simple declaration.
Fig. 6 and Fig. 7 represent its relation, and wherein, Fig. 6 is a bonding angle when representing with bonding first sheet material of crimping roller and second sheet material
θLittle of the following occasion of 10 degree, Fig. 7 is a bonding angle when representing with bonding first sheet material of crimping roller and second sheet material
θGreatly to the above occasion of 30 degree.Fig. 8 is illustrated in the sectional view that the reflection of light state of bonded sheet material under the bubble state is arranged between first sheet material and second sheet material, and Fig. 9 is illustrated in the sectional view that does not have the reflection of light state of bonded sheet material under the bubble state between first sheet material and second sheet material.If bubble gets into, then the light from transparent medium reflects in bubble, and refract light becomes diffuse reflection, can see light, and the homogeneity of white portion gets muddled.
Can know by Fig. 6; The little occasion of bonding angle intersects junction surface (adhesive portion) 103 and is positioned at crimping roller 95a, before the 95b; Bubble 104 is formed between the adhesive layer 91b of mirror image 100a and second sheet material 91 of first sheet material 100; Even at crimping roller 95a, 95b is extruded bonding, bubble 104 also can not disappear and be remaining.Like this; If between the adhesive layer 91b of the mirror image 100a of first sheet material 100 and second sheet material 91, form bubble 104, then as shown in Figure 8, reflect in bubble 104 from light as first sheet material 100 of transparent medium; Refract light becomes diffuse reflection; Can see light, the homogeneity of white portion gets muddled, infringement image glossiness or texture.
On the other hand; As shown in Figure 7, when bonding angle θ greatly to the above occasion of 30 degree, intersecting junction surface (adhesive portion) 103 becomes crimping roller 95a; Near the 95b, be suppressed between the adhesive layer 91b of mirror image 100a and second sheet material 91 of first sheet material 100 and form bubble 104.As a result, as shown in Figure 9, there is not the homogeneity of white portion of the base material 91a of toner image 100a to be maintained, can obtain glossiness and texture preferable image.As the bonding angle θ that can suppress to form bubble, more than preferred 30 degree, less than 90 degree, that is, and 30 °≤θ＜90 °.
If second sheet material 91 is a relaxed state, then can produce from desirable bonding position skew again; Be bonded on first sheet material (transparent recording medium) 100 with no intention state, use crimping roller 95a, during the 95b crimping; Produce wrinkle; Perhaps if oblique buckling problem then takes place for device front side and the inboard lax deviation that has, increasing maybe towards what sneak into bubble between medium.
As stated, if took place to relax in the device in the past, then because of its influence, when using crimping roller 95a, when 95b crimping first sheet material 100 and second sheet material 91, it is big between sheet material, to form the bubble possibility.
So, in this example device, for the influence that suppresses to relax; Bonding angle θ is maintained proper states; As shown in Figure 4, plate member (blade) 110A as the tension force member of imparting is set, it is positioned at the upstream side of the separation point position 105 that is used to separate peeling paper; Give second sheet material 91 with tension force, with 91 crimping of second sheet material.Make plate member 110A have elasticity (elastic plate), relative peeling paper carriage direction, plate member 110A is crimping in the opposite direction.
Like this, the lax prevention of second sheet material 91 that is positioned at 105 upper reaches, separation point position is at the upstream side of plate member 110A, and second sheet material 91 in plate member 110A downstream is not lax, and the separation angle of base material (non-transparent medium) 91a and peeling paper can be necessarily.
The carriage direction of second sheet material of seeing off like this 91 with intersect through transporting the passage that transports that roller 97 transports first sheet material 100 that comes; The leading section 911 of second sheet material 91 intersects with the leading section 101 of needed angle (angle of relative first sheet material 100) and first sheet material 100 and joins (intersecting junction surface 103); The leading section 101 of bonding first sheet material 100 of adhesive layer 91b through second sheet material 91 and the leading section 911 of second sheet material 91; Transport the passage extending direction along first sheet material 100; Towards crimping roller 95a, 95b transports, at crimping roller 95a; 95b can be reliably be bonded as one the base material 91a of first sheet material 100 and second sheet material 91 through adhesive layer 91b.
Before intersect engaging, remove the lax of second sheet material 91 through plate member 110A, make separation angle keep certain, therefore, can carry out good bonding.Like this, can prevent that mistake is bonding, prevent that between two media bubble gets into when bonding, can keep the homogeneity (with reference to Fig. 9) of the white portion that does not have toner image of resulting sheet shape body.
After this, first sheet material 100 and second sheet material 91 are bonding to be a sheet body, by transporting roller 98 fortune downwards, positions at the front end that does not have illustrated positioning element to the sheet body, cuts into institute's shaped with cutting knife 99a and 99b, leaves in and coils on 102.The sheet body that cuts into institute's shaped also can not leave dish 102 in, and is discharged to outside the device.
In this example, as shown in Figure 3, the upstream side at the crossing junction surface (adhesive portion) 103 of first sheet material 100 and second sheet material 91 is provided with sensor 111 and 112; As the detection part of the sheet material that is transported, can detect the leading section 101 of first sheet material 100 and the leading section 911 of second sheet material 91 respectively, through the sensor 111 and 112; Can detect remarkable action, again, the leading section 101 through detecting first sheet material 100 and the leading section 911 of second sheet material 91; The control travelling speed, the ability inching time, control makes between the above-mentioned sheet material leading section consistent; Transport first sheet material 100 and second sheet material 91, both front positions of inching make its unanimity.
As stated, according to this example, be provided in the upstream side at crossing junction surface as the plate member 110A of tension force member of imparting; Join with the opposite sides of the bonding side of second sheet material 91, therefore, even as shown in Figure 4; The nontransparent white medium of peelling off behind the peeling paper (second sheet material) 91 advances, and lax because of removing, it is certain that separation angle can keep; Can obtain stable bonding angle, can avoid between two media in the contact of undesirable position, during bonding two sheet materials (medium); Prevent that bubble from getting into, can keep not having the homogeneity of the white portion of toner image, can be easily and reliably making have that glossiness is good, the sheet material of texture good images.
