Description
Technical field
The present invention relates to and a kind of the sheet-shaped recording medium such as plurality of sheets of paper or OHP sheet (hereinafter referred to as " sheet medium ") are carried out piling the image processing system that the sheet-shaped recording medium processing equipment (hereinafter referred to as " sheet media processing apparatus ") that (i.e. " alignment ") process and the chopping machine, duplicator, facsimile apparatus etc. with this sheet media processing apparatus are integrated in superimposition.
Background technology
In the prior art, a kind of image processing system known has sheet media processing apparatus, and this sheet media processing apparatus carries out the post-processings such as integration process and binding process to the sheet medium being defined image by image forming part.In this sheet media processing apparatus, multiple the sheet media moved are stacked in a pile on bookbinding dish (i.e. " sheet medium pile "), and in sheet medium conveyance direction, integration process is carried out to this sheet medium pile, then, integration is carried out to it again in the sheet media width direction orthogonal with sheet medium conveyance direction and this both direction of sheet medium stacking direction to process.Afterwards, at the gutter pos place of the sheet medium pile that integrated process is integrated, binding needle is squeezed into by the attachment means as stapling unit, to implement binding process.
The sheet media processing apparatus that following patent documentation 1 is recorded has: bookbinding dish, and its plane upper surface tilts certain angle, with the below making the upstream side of sheet medium conveyance direction be positioned at downstream; Rear end benchmark fence, it is configured in the upstream-side-end of the conveyance direction of bookbinding dish; And a pair fence (i.e. " alignment fence " (jogger fence)), it is configured in the top of bookbinding dish upper surface.
The upper surface of the bookbinding dish that this sheet media processing apparatus has is inclined relative to horizontal more than miter angle, and the upper surface that the sheet medium draining into bookbinding dish tilts along bookbinding dish is slipped to the upstream side of conveyance direction by deadweight.Accordingly, the rear end of the conveyance direction of sheet medium is touched by rear end benchmark fence, to realize the integration of sheet medium in conveyance direction.
In addition, the both sides of the above-mentioned Width of a pair alignment fence above bookbinding dish upper surface are arranged in opposite directions, and can move in opposite directions along sheet media width direction by the position of readiness also larger than sheet media width from its interval between the two.Make it close to each other from position of readiness by mobile above-mentioned a pair alignment fence, and the medial surface of its Width is abutted with the two ends in sheet media width direction, to realize the integration on the Width of sheet medium pile stacking on bookbinding dish.
But, be supplied in the sheet medium of sheet media processing apparatus the situation that warpage (i.e. " end warpage " (side face curl)) may occur, in the planar structure that the upper surface of bookbinding dish is only smooth, the warped state of sheet medium may cause carrying out the integration based on the Width of alignment fence fully.
When the end in sheet media width direction there occurs the end warpage of upwards floating parallel with conveyance direction, the width being in the sheet medium of this state shortens in fact, the amount that the end that shortening amount is equivalent to sheet media width direction is floated due to warpage.Like this, under the state that there occurs end warpage, sheet medium can not be moved to the inner side of its Width by alignment fence, is difficult to realize integrating.In addition, under the state that there occurs end warpage, even if make alignment fence move to the position also shorter than the length in sheet media width direction, interval both it in opposite directions, when the fence that aligns contacts with the end in sheet media width direction, sheet medium also can bend due to its end warpage.When flexure occurs due to end warpage sheet medium, the displacing force in opposite directions of the Width of alignment fence can be absorbed, and causes carrying out the integration on the Width of sheet medium pile fully.
As the structure of the sheet medium pile comprising the sheet medium that there occurs end warpage being carried out rightly to the integration on Width, the sheet media processing apparatus of patent documentation 1 has convex face, and it is arranged in a part for the conveyance direction on bookbinding dish; And pressing mechanism, it makes concavity face along the direction pressing tablet medium orthogonal with bookbinding dish upper surface, complies with above-mentioned convex face to make sheet medium.In this sheet media processing apparatus, to touching by rear end benchmark fence and by the sheet medium pressing concavity face on the bookbinding dish of the integration of carrying out conveyance direction.Accordingly, the part clamped by convex face and concavity face of the sheet medium on bookbinding dish becomes and raises up, " ヘ " shape that like this, sheet medium is just stacked as on bookbinding dish " two ends downwards in the middle of upwards ".In this sheet media processing apparatus, even if the sheet medium be expelled on bookbinding dish there occurs end warpage, because the part in the conveyance direction of sheet medium is bent into convex, this end warpage also can be corrected.Because can correct end warpage, so the sheet media processing apparatus of patent documentation 1 can be stacked on the sheet medium comprising the sheet medium that there occurs warpage on Width carry out appropriate integration.
But, in the sheet media processing apparatus of patent documentation 1, because need one make concavity face move and make the pressing mechanism of its pressing tablet medium along the direction orthogonal with bookbinding dish upper surface, so cause the problem having occurred larger-scale unit.
Here it should be noted that, in the above description, although to sheet media processing apparatus by sheet medium stacking in a pile and the structure of carrying out binding process again after carrying out integrating process be illustrated, as sheet media processing apparatus, and not necessarily all will carry out binding process.In other words, integrate process to such as only carrying out or integrate the sheet media processing apparatus being different from other process of binding process after process terminates again, as long as by sheet medium stacking in a pile and carry out integrate process sheet media processing apparatus, all can there is problem similar to the above.
Patent documentation 1:(Japan) " No. 4141113rd, patented invention "
Summary of the invention
The present invention proposes in view of the above problems, its object is to provide a kind of carry out integrating the sheet media processing apparatus of process and there is the image processing system of this sheet media processing apparatus to sheet medium pile, this sheet media processing apparatus not only can miniaturization of the apparatus, but also can be stacked on the sheet medium comprising the sheet medium that there occurs end warpage on Width and carry out appropriate integration.

In sheet above media processing apparatus, the convex shaped part abutted against with the lower surface of the sheet medium that described loading tray loads makes the part except front-end and back-end in the conveyance direction of sheet medium upwards be pressed and protruding, " ヘ " shape at " two ends downwards in the middle of upwards " being bent to by sheet medium.In the sheet media processing apparatus that patent documentation 1 is recorded, a part for the conveyance direction on loading tray (bookbinding dish) has convex face, and the convex shaped part of the sheet above media processing apparatus of this convex face and embodiment of the present invention has similar structure.But, here it should be noted that, when being upwards pressed making the centre portion of sheet medium to make sheet medium bend to " ヘ " shape, need, in the front of sheet medium and rear end side, there is the power acted on downwards, in order to resist mutually with the waist of sheet medium, like this, when sheet medium is pressed, centre portion just can be upturned.
But, because the upper surface of the loading tray that the sheet media processing apparatus of patent documentation 1 has is for being inclined relative to horizontal more than 45 degree, so act in the component of the gravity of sheet medium, the component along inclined direction acted on is comparatively large, and the component acted on towards loading tray is less.In addition, because the inclination at convex face place is larger, so the component acted on towards loading tray is less herein.Therefore, compared with the centre portion by convex face institute jack-up, the more difficult effect of the power towards loading tray caused by the deadweight of sheet medium is to the sheet medium of front, like this, when the loading tray with convex face piles laminated dielectric, the waist of sheet medium can cause front to be in the state of floating, and is difficult to sheet medium to bend to " ヘ " shape.Therefore, as mentioned above, in the sheet media processing apparatus of patent documentation 1, in order to make sheet medium bend to " ヘ " shape to correct end warpage, need that there is the pressing mechanism by concavity face, sheet medium being pressed into convex face.
But, in the sheet above media processing apparatus of embodiment of the present invention, because loading tray upper surface angle of inclination is with respect to the horizontal plane less than 30 degree, close to level, so act in the component of the gravity of sheet medium, towards the loading tray being positioned at below, the component that acts on is comparatively large, and the power towards loading tray caused by deadweight can easily act on to sheet medium.Accordingly, the part contacted with convex shaped part of the sheet medium on loading tray raises up, and the both sides of this projection and front and rear end side can be bent downwardly on the contrary because of deadweight and sheet medium waist direction, like this, sheet medium will bend to " ヘ " shape and be stacked.Therefore, bent to by a part for the conveyance direction of the sheet medium by there occurs end warpage and raise up, just can correct this end warpage.Like this, because even without pressing mechanism, by the deadweight of sheet medium, a part for sheet medium also can bend to and raise up, so not only can miniaturization of the apparatus, but also can correct end warpage.
Afterwards, in end warpage by under the state of having corrected, carry out sheet medium registration process in the direction of the width by Width integral unit, like this, just can be stacked on Width the sheet medium that loading tray loads fully and carry out actv. integration.
Accordingly, embodiment of the present invention to sheet medium pile carry out integrate process sheet media processing apparatus there is following effect, that is: not only can miniaturization of the apparatus, but also can be stacked on the sheet medium comprising the sheet medium that there occurs end warpage on Width and carry out appropriate integration.

< rotation ADF pattern >
Rotation ADF pattern is the pattern of the paper S that have passed fixation unit 76 being carried out to post-processing according to the setting pre-entered, and this post-processing on paper width direction, changes the drain position of ADF dish 6 to carry out the process of ADF according to the kind etc. of such as paper S.This pattern can be used for the situation of the paper pile forming multiple kind, by changing the position of the Width of drain position when often discharging the paper pile of a part of kind, make it not overlap, the function of the paper S of other kinds in piling up with the paper realizing one species, can not be mixed with.
After the paper S that moves is imported sheet carrying pathway L by entrance roller to 2 by paper processing device 200, via relaying roller to (nip) between 3, be imported into wheel roll change to (nip) between 4.Next, paper S is transported to exit roller to 5; Under rotation ADF pattern, ADF top roll 5a movable is up and down positioned at top, and exit roller receives paper S to 5 under its occlusion (nip) is in open state.Form wheel roll change to 4 rotation top roll 4a and rotation lower roll 4b can move along paper width direction relative to the main body of paper processing device 200, but, form relaying roller to 3 relaying top roll 3a and relaying lower roll 3b can not move along paper width direction.Accordingly, when paper width direction making the ADF position of paper S move (rotation), only by taking turns roll change under the states of 4 clamping paper S, rotation top roll 4a and rotation lower roll 4b can be made to move.
The have stateless of optical profile type inlet sensor S1 to the paper S of detection position detects, if detection position exists paper S, then inlet sensor S1 becomes ON.Accordingly, the rear end being paper S opportunity that inlet sensor S1 becomes OFF again after becoming ON have passed the opportunity of the detection position of inlet sensor S1.So, by inlet sensor S1 is become become OFF after ON again opportunity as energizing signal, according to the conveyance speed of paper S, can detect from the detection position of inlet sensor S1 arrive relaying roller to 3 gap (nip) required for certain hour after paper S1 rear end by relaying roller to 3 opportunity.
Accordingly, under rotation ADF pattern, the rear end of paper S have passed relaying roller to 3 gap (nip) after and, the rear end of paper S by wheel roll change to 4 gap (nip) before opportunity, can on paper width direction (front side in Fig. 4 and inboard), make rotation top roll 4a and rotation lower roll 4b move.Like this, just can make to be moved by the wheel position of roll change to the paper width direction of the paper S clamped by 4.
After terminating based on the mobile process of wheel roll change to the paper S of 4, ADF opening and closing guide plate 70 is rotated in the counterclockwise direction, ADF top roll 5a is abutted against via paper S and ADF lower roll 5b, form (nip) state of nipping, to be nipped by paper S.Afterwards, in this case, by the rotation of ADF top roll 5a and ADF lower roll 5b, along the arrow B direction in Fig. 4, paper S is transported and is expelled to ADF dish 6.
Under rotation ADF pattern, in the same manner as direct ADF pattern, when ADF action starts, as shown in phantom in figure 4, the upper surface of movable ADF dish 6a is also the position close to level.The paper S be expelled on ADF dish 6 slides, and is stacked under the state abutted with end fence 7 in its back-end on movable ADF dish 6a.
Paper S piles poststack on movable ADF dish 6a, is detected the paper height on movable ADF dish 6a by paper press section 18 and optical profile type carrying capacity sensor S3; Control unit not shown in the figures makes the upstream side of movable ADF dish 6a slowly decline according to the carrying capacity of paper S.The upstream side of movable ADF dish 6a declines slowly, after arriving the position shown in solid line in Fig. 4, the light path of the full quantity sensor S4 of optical profile type interdict by the filling part 6s of movable ADF dish 6a, go out result between full quantity sensor S4 and become ON.Accordingly, by being detected that from control part not shown in the figures movable ADF dish 6a becomes full amount, the decline of movable ADF dish 6a can be made to stop.
< binds ADF pattern >
Bookbinding ADF pattern is by a pile stacking for the paper S that have passed fixation unit 76, then carries out the pattern of binding (post-processing) by attachment means.
The action specification figure of paper S when Fig. 1 and Fig. 2 is bookbinding ADF pattern.Fig. 1 is the instruction diagram that the opportunity after taking turns the right gap (nip) of roll change is passed through in the rear end of paper S, and Fig. 2 is the instruction diagram on the opportunity of arrival rear end, paper rear end benchmark fence 13.
After the paper S that moves is imported sheet carrying pathway L by entrance roller to 2 by paper processing device 200, via relaying roller between 3, be imported into wheel roll change between 4.Next, paper S is transported to exit roller to 5; Under bookbinding ADF pattern, in the same manner as rotation ADF pattern, ADF top roll 5a movable is up and down positioned at top, and exit roller is in open state to the occlusion between 5, and in this case, exit roller receives paper S to 5.Then, under bookbinding ADF pattern, the rear end of paper S by relaying roller to 3 opportunity after, exit roller is also in open state to the occlusion between 5; The rear end of paper S is by wheel roll change to after between 4, and the rear end side of paper S is discharged on bookbinding dish 90.
Under bookbinding ADF pattern, it is after 90s that paper S is discharged to bookbinding dish, pat roller support sector 10a to rotate along the anticlockwise direction in Fig. 3 centered by support sector axis of rocking 70a, beating roller 10 is contacted with the upper surface of the paper S on bookbinding dish 90 as shown in dashed line in figure 2 like that.Then, return roller 12 by making beating roller 10 and rear end and rotate along the anticlockwise direction in figure, the direction along the arrow C in Fig. 2 pushes back paper S.Like this, by paper S is sent into benchmark fence 13 side, rear end, and the rear end of paper S and rear end benchmark fence are abutted against, the vertical registration process of the paper pile of paper S can be carried out.Afterwards, alignment fence 11 being moved, by carrying out horizontal registration process again to the paper pile of the paper S be stacked on bookbinding dish 90, just can integrate this paper pile.
It is after 90s that paper S control part by duplicator 100 being specified in advance quantity is stacked to bookbinding dish, piled up carry out binding process by stapling unit 14 pairs of paper.After binding process terminates, ADF top roll 5a declines, and is piled up, and be expelled on ADF dish 6 by exit roller to 5 clamping paper.
Here, bookbinding dish front sensor S5 is optical sensor, is for the sensor whether bookbinding dish 90 existing paper S and detect.In addition, bookbinding back-end disk side senser S6 is the sensor detected the rear end of paper S, sends the signal that can carry out binding process, send the signal forbidding binding process during OFF when bookbinding back-end disk side senser S6 is ON, accordingly, the blocking of the binding needle of stapling unit 14 can just be prevented.
Here it should be noted that, though exit roller to 5 occlusion (nip) be open state under, if paper S and ADF lower roll 5b come in contact, then the direction become along the arrow C in Fig. 2 pushes back the obstruction (resistance) during paper S.For this reason, near the end of downstream side of bookbinding dish 90, be formed with jut not shown in the figures, its can exit roller to 5 occlusion be open state time, prevent paper S from contacting with ADF lower roll 5b.This jut gives directionality to a certain degree to the paper S on the direction-sense bookbinding dish 90 had to a certain degree, by the intensity of the waist of this directionality and paper S, can avoid the contact of paper S and ADF lower roll 5b.Like this, avoiding under the state that paper S contacts with ADF lower roll 5b, ADF top roll 5a is declined to form exit roller to after the occlusion (nip) of 5, compared with the waist of paper S, the pressure of ADF top roll 5a is stronger, like this, the nethermost paper S in the paper S on bookbinding dish 90 contacts with ADF lower roll 5b, and can give conveyance power by exit roller to 5 couples of paper S.
Below the features of the paper processing device 200 of this example is described.
The inclination of the upper surface of bookbinding dish 90 is the inclinations close to level, and the end of downstream side of bookbinding dish 90 has the paper lower surface press section 15 be made up of elastomeric element, and it protrudes from the plane upper surface of bookbinding dish 90.The half of the upstream side of paper lower surface press section 15 is fixed on bookbinding dish 90 in the mode of the upper surface shape complying with bookbinding dish 90, and the half in downstream tilts in the mode of " more toward downstream more upwards ", protrudes from the upper surface of bookbinding dish 90.
The end of Width be there occurs to the paper S of end warpage (sideface curl) of floating parallel with conveyance direction, its width shortens in fact, the amount that the end that shortening amount is equivalent to Width is upwards floated because of warpage.Accordingly, under the state that there occurs end warpage, alignment fence 11 can not make paper S move to the inner side of its Width, is difficult to carry out integration.In addition, under the state that there occurs end warpage, even if alignment fence 11 in opposite directions moves to position also shorter than the length of the Width of paper S, the interval both it to the inside, when alignment fence 11 contacts with the end of the Width of paper S, paper S also can bend because of above-mentioned end warpage.Paper is once bend because of end warpage, and the displacing force of the Width of alignment fence 11 will be absorbed, and like this, just can not carry out the integration of the Width of paper pile fully.
In the paper processing device 200 of this example, when transporting paper S under bookbinding ADF pattern, the paper S moved is discharged to bookbinding dish 90, and is pushed back along the arrow C direction in Fig. 2 by beating roller 10.Now, the paper lower surface press section 15 be arranged on bookbinding dish 90 makes a part of paper S float.Because bookbinding dish 90 is close to level, the weight (deadweight) of paper S is easy to have an effect towards the bookbinding dish 90 below it.Accordingly, paper S on bookbinding dish 90, the part that contacts with paper lower surface press section 15 raises up, the both sides of this projection and front and rear end side are then bent downwardly because of deadweight, like this, paper S will bend to " ヘ " shape, and is stacked (with reference to Fig. 2).Therefore, become convex by a part (centre portion) K/UP of the conveyance direction making the paper S that there occurs end warpage (side facecurl), can correct this end warpage.
Even if because there is not pressing mechanism as described in Patent Document 1, rely on the deadweight of paper S that a part for the conveyance direction of paper S also can be made to bend to convex, so not only can miniaturization of the apparatus, but also can correct end warpage.In addition, by paper lower surface press section 15 being configured in two positions of the Width of the upper surface of bookbinding dish 90, paper S can also be made in the universe of Width to bend to convex, like this, just can more effectively correct end warpage.
Afterwards, in end warpage by under the state of having corrected, carried out the horizontal registration process of paper pile by alignment fence 11, so just can carry out the integration of the Width of paper pile fully.
In the paper processing device 200 of this example, the length of the conveyance direction of bookbinding dish 90 is less than the length of the conveyance direction of the paper S of the minimum size in spendable antiquarian.Accordingly, under the state that bookbinding dish 90 is stacked paper S, as shown in Figure 2, the upstream side of the conveyance direction of paper S is the state of the movable ADF dish 6a being maintained at ADF dish 6.Now, movable ADF dish 6a forms sheet media retention tray together with bookbinding dish 90.
In the paper processing device 200 of this example, the minimum size that can carry out the paper S of post-processing is that B5 is longitudinal; Under the state that the A5 paper be discharged along longitudinal direction contacts with rear end benchmark fence 13, paper lower surface press section 15 contacts in the position of the 14cm from top of form.In addition, the upper surface of bookbinding dish 90 is 10 degree of angles relative to the inclination of level, from the upper surface of bookbinding dish 90 to the height of the upper end of paper lower surface press section 15 be 4.5mm.By such structure, when the common paper (NBS Ricoh copy paper <90>B5Y) of B5 is expelled on bookbinding dish 90, also front forward bend downwards than the contact position of paper lower surface press section 15, like this, paper S just can be made in " ヘ " shape.
Here it should be noted that, the length of bookbinding dish 90 also can be greater than spendable maximum sized paper S, and plays the function as sheet media retention tray (loading tray) using the form of monomer.When the length of the conveyance direction making bookbinding dish 90 is greater than the length of paper S of spendable minimum size, paper lower surface press section 15 is not configured in the end of downstream side of bookbinding dish 90, and need the paper S being configured in minimum size to bend by gravity energy in the front of the contact position of paper lower surface press section 15 and rear end side, and the position of paper S in " ヘ " shape can be made downwards.
In addition, as shown in the paper processing device 200 of this example, the length of the conveyance direction of bookbinding dish 90 is less than the length of spendable paper S, and movable ADF dish 6a has reached the function of sheet media retention tray (loading tray) together with bookbinding dish 90, accordingly, the problem of the maximization of the horizontal direction occurred because of the paper processing device 200 being configured to cause close to level by bookbinding dish 90 can be avoided.
Paper S after 2nd complies with the shape of the 1st, is also all stacked as " ヘ " shape; Equally, the end warpage (side face curl) of the paper S after the 2nd also all can be corrected on ground.In addition, the half inclined in the downstream of paper lower surface press section 15 be more toward downstream more upwards, accordingly, when carrying out ADF to the paper pile that have passed through binding process, because the paper lower surface press section 15 be made up of elastic body elastic deformation can occur, hinder so the paper lower surface press section 15 raised up by the upper surface of bookbinding dish 90 can not produce ADF.
On bookbinding dish 90 during stack paper S, in order to the end warpage (side face curl) to the ora terminalis parallel with conveyance direction is corrected, and good alignment is carried out on the Width of paper pile, need the end warpage near to alignment fence 11 to correct.Accordingly, paper lower surface press section 15 is preferably and is arranged near alignment fence 11.But, in order to not hinder the action of the alignment fence 11 when carrying out Width registration process, need not to be arranged in the sliding scale of alignment fence 11.In addition, in order to correspond to various antiquarian, the setting position of paper lower surface press section 15 is configured in the position being narrower than and can carrying out the width of the paper of the minimum size of binding process.Further, exit roller to 5 occlusion (nip) be in open state under, in order to not make paper S contact with ADF lower roll 5b, paper lower surface press section 15 is configured to higher than above-mentioned jut not shown in the figures set on bookbinding dish 90.In addition, in order to avoid the error detection of bookbinding dish front sensor S5, paper lower surface press section 15 is set to have an angle, to make the lower surface of the paper S held up by paper lower surface press section 15 lower than the detection range of bookbinding dish front sensor S5.
In addition, with regard to paper lower surface press section 15, as long as can the upper surface of bookbinding dish 90 relatively project upwards, not needing must be elastomeric element.But, although end warpage (side facecurl) also can be eliminated when paper lower surface press section 15 is the convex of not flexible solid shape, but, when carrying out ADF to stacking paper pile, can produce conveyance and hindering (resistance).If this conveyance resistance during ADF is excessive, just easily there is paperboard.In this example, paper lower surface pressing component 15 adopts elastomeric element, during ADF, by making its elastic deformation, conveyance during ADF can be suppressed to hinder, and then suppress the generation of paperboard.
In the paper processing device 200 of this example, as the elastic body for the formation of paper lower surface press section 15, employ polyester film (polyester film) (Japanese Toray Inc. Lumirror S10 (thickness: 0.125mm)), but the present invention is not limited thereto.
The upper surface of the bookbinding dish 90 of this example is below 30 degree of angles relative to the inclination of level, close to level.Accordingly, with have larger leaning angle bookbinding dish paper processing device of the prior art (in patent documentation 1 described device etc.) compared with, the size of above-below direction can be reduced.
In the duplicator 100 of this example, the paper S defining image above developer bottle 9 and the below of scanner 300, be discharged in space that the size of above-below direction has been limited.On the duplicator 100 with such structure, need a paper processing device that the size of the horizontal direction of device can not be made to increase, and when configuring this paper processing device, it can also be configured in the confined space of size of the above-below direction that paper S is discharged.
As mentioned above, the paper processing device 200 of this example can realize miniaturization in the vertical direction, so, as shown in Figure 3, for duplicator 100, when it configuring paper processing device 200, the size of the horizontal direction of device can't be made to increase.
