In the sheet post-process apparatus 100 that constitutes like this, preparation has a plurality of paper sheet delivery that will carry, is expelled to the unit of pile dish 13 in sheet post-process apparatus, roughly can be divided into two kinds of path of carrying out post-processing and the path of not carrying out post-processing.
(situation of post-processing)
Situation during at first, to the post-processing paper describes.As post-processing, the classification processing of handling and being used to get all the ready paper by the bookbinding of the bundled paper of binding device is for example arranged.
The paper that is used for post-processing that will transport from image processing system at first is transported to the standby dish 3 in the sheet post-process apparatus.In such conveying, make the inlet roller motor (not shown) just change, with drive transmitting to roller 1 and the outlet roller 2 of entering the mouth.After the temporary transient pile of the paper of outlet roller 2 is on standby dish 3, it is fallen and offers process disk 4.
When newly transporting paper, if process disk 4 is being carried out in the last handling process or when discharging the paper of carrying after the post-processing, then make paper P standby in the standby dish 3 that temporarily can keep for next post-processing.
Image forms and a series of performances of post-processing in order to improve, and preferably can make multipage paper standby (buffer) on standby dish 3, to guarantee the post-processing time.But, only be pile when having the paper of quality respectively and making its standby, for pile the paper of midway location of multipage paper be difficult to transmit the power of the adjustment that is used for throughput direction, therefore, when the paper of standby is sent into process disk 4, adjust confusion can take place.In addition, compare with paper long-time standby in standby dish 3, pile can be realized conforming stable in the process disk 4 that can carry out pile in the mode that covers the paper width total length.
In the related sheet post-process apparatus 100 of present embodiment, when process disk 4 fell, the pile in the standby dish of being realized can obtain the good vertical consistency on the process disk at the multipage paper P more than two pages or three pages of standby.
Below, the method for three pages of paper of pile describes on the subtend standby dish 3.
(first page of paper is towards the pile of standby dish)
Below, describe with reference to Fig. 6, Fig. 7.Fig. 6 is used to illustrate the situation of carrying to standby dish 3 piles for first page of paper.Fig. 7 is used to illustrate that first page of paper pile is in the situation of standby dish 3.
At first, in the time of near first page of top of form being delivered to live-rollers 14, make live-rollers open and close magnet MG action, make live-rollers 14 rise 4～5mm (being not limited to this scope) to hoisting position.Rotary electric machine (not shown) is just changeed, live-rollers 14 is rotated along throughput direction.This is to run into live-rollers 14 (with reference to Fig. 6) for the first page of top of form that prevents to transport.
Because standby dish 3 is with the mode tilted configuration that the upstream side position is low, the position, downstream is high of throughput direction, therefore, first page of paper of discharging from outlet roller 2 passes through deadweight, and pile is on the P3 of standby dish 3 and blade 5.Behind the pile, make actions such as o (electromagnetic solenoid) ES, clamp lever 3a is rotated along arrow Q direction, keep the paper rear end.Clamp lever 3a one end is equipped with and o ES bonded assembly ring 3c, another distolateral surface and rubber-like holding member (gripping member) 3b (for example, poly-urethane rubber thin slice) that comprises great friction coefficient that be bonded with.By the action of o ES, ring 3c is pulled and turns to the position (with reference to Fig. 6) that maintaining part 3b pushes upper sheet surface along arrow R direction.
First page of complete pile of paper after standby dish 3 (with reference to Fig. 7) makes live-rollers 14 descend from hoisting position along arrow D direction, with paper by being pressed on the standby dish 3.Thus, can push top of form and rear end together.This is to remain on the standby dish 3 for first page of paper stablized.
(second page of paper is towards the pile of standby dish)
Below, second page of paper described towards the pile of standby dish 3.Fig. 8 is used to illustrate the conveying situation that second page of paper carried to the standby dish.Fig. 9 is used to make first page of paper and second page of paper to stagger the front end pile in the situation of standby dish 3.Figure 10 is used to illustrate with the situation of second page of paper to standby dish 3 piles.
In the time of near second page of top of form is delivered to live-rollers 14, make live-rollers open and close magnet MG action, make the live-rollers 14 that first page of paper clamp is held on the standby dish 3 rise to hoisting position.And, under this state, rotary electric machine is just changeed, along throughput direction rotation (with reference to Fig. 8).This is when supposing that second page of paper run into live-rollers 14, also can weaken the load of impact, and paperboard does not take place.
At this moment, first pile nips (plucking む) in the clamped handle 3a in the rear end of first page of paper of standby dish 3, though and live-rollers 14 rotate along throughput direction, owing to it is positioned at hoisting position, therefore, can not carry first page of paper.
Afterwards, fall at second page of paper, before pile finishes to standby dish 3, decontrol paper rear end first page of paper, that picked the P3 upper surface of (being clipped in) clamp lever 3a and blade 5, and arrive the timing of position that on upstream side first page of top of form of distance staggers assigned position with second page of top of form, keep the live-rollers 14 that is positioned at hoisting position is rotated to throughput direction, through behind the specified time, it is descended along arrow D direction.
By this action, under the state (on throughput direction, first page of top of form is leading than second page of top of form) that keeps first page of paper and second page of paper to stagger, carry two pages of paper in front.Here, the amount of staggering with first page of paper and second page of paper is set at 5～20mm (more than or equal to 5mm and smaller or equal to 20mm).For example, consider the change of landing in falling, preferably the amount of staggering is 10mm.Promptly, the pulse of calculate carrying the pulse motor PM of second page of paper, become the timing of 10mm with the difference of the front end of two pages of paper, live-rollers 14 in the rotation descended and nip.Like this, to till the 2 discharge end, first page of paper and second page of paper while downstream are carried by live-rollers 14 to second page paper rear end from outlet roller, after discharging end, the rotation (with reference to Fig. 9) of the roller 14 that stops operating.Second page of paper fallen on the standby dish 3 and above the P3 of blade 5 by deadweight under the state that keeps the top of form position to stagger.
Afterwards, the same with first page of paper after pile is on the P3 of blade 5, the rear end (with reference to Figure 10) that keeps second page of paper by clamp lever 3a.
Thus, top of form portion of staggering in the holding position and paper rearward end, the pile of two pages of paper on the end standby dish 3.
(the 3rd page of paper is towards the pile of standby dish)
Below, the 3rd page of paper described towards the pile of standby dish.Figure 11 is used to illustrate the situation of carrying to standby dish 3 piles for the 3rd page of paper.Figure 12 is used to illustrate second page of paper and the 3rd page of paper is staggered specified amount and carry the also situation of pile from first page of top of form.Figure 13 is used to illustrate the situation of the 3rd page of paper to standby dish 3 piles.
In the time of near the 3rd page of top of form is delivered to live-rollers 14, make live-rollers open and close magnet MG action, make first page, second page paper risen to hoisting position by the live-rollers 14 that is pressed on the standby dish 3.And, under this state, rotary electric machine is just changeed, make live-rollers 14 along throughput direction rotation (with reference to Figure 11).
At this moment, first pile nips in the clamped handle 3a in the rear end of first page, second page paper of standby dish 3, though and live-rollers 14 rotate along throughput direction, owing to it is positioned at hoisting position, therefore, can not carry first page, second page paper.
Finish that the 3rd page of paper rear end falls and pile in the standby dish 3 before, promptly, drive the pulse of outlet roller to 2 pulse motor PM by calculating, at the roughly overlapping moment of front end of the front end and the 3rd page of paper of second page of paper, stop pulse motor PM.In addition, when decontroling clamp lever 3a, make the live-rollers 14 that is positioned at hoisting position under the state that rotates along throughput direction, along arrow D direction decline (with reference to Figure 12).At this moment, because live-rollers 14 is along throughput direction rotation, therefore, though with paper sheet delivery side downstream,, through after several pulses, the rotation of the roller 14 that stops operating.
By this action, under the situation that the staggered positions that does not change first page and second page concerns, the 3rd page of paper is overlapping in the mode of aliging with the front position of second page of paper on second page of paper.
The pile amount of staggering of three pages of paper on standby dish 3 is: first page of paper is positioned at the leading position of conveyance direction downstream side, and second page, the 3rd page is positioned at from this position upstream that side staggers on the position of 10mm roughly.With this position relation, by live-rollers 14 with each paper by being pressed in (with reference to Figure 13) on the standby dish 3.At this moment, at the paper that next will not carry or when not having the needing of standby, need not paper rear end by second page of clamp lever 13 (nipping) and the 3rd page.
As mentioned above, when implementing paper number of pages that bookbinding handles and reaching three pages, after cushioning by standby dish 3, the pair of support parts part that constitutes standby dish 3 is opened mobile along paper width direction, paper is fallen be provided on the process disk 4.Therefore, since fall the paper that is provided on the process disk 4 be from paper rear end land on process disk 4, so the vertical consistency on the process disk 4 is good.
In addition, follow-up when wanting the 4th page of paper of standby when also having, carrying pile, when pushing down, be buffered in the standby dish 3 and get final product by live-rollers 14 and clamp lever 3a with the 3rd page of same processing.
(the not processing of Huan Chong the 4th page of later paper)
The paper number of pages of buffering is three pages in standby dish 3, the paper number of pages of carrying out post-processing is more than four pages the time, at first, makes three pages of paper of buffering in the standby dish 3 fall process disk 4.Then, follow-up paper temporarily discharge pile on standby dish 3 after, make paper fall (with reference to Figure 14) on the process disk 4 page by page.About the 5th page or the 6th page of later paper, also carry out same processing.Paper temporarily discharge pile on standby dish 3 after, always from the paper rear end side paper being fallen provides to process disk 4, thus, the vertical consistency of the paper that falls on process disk 4 is good.
In addition, about the 4th page of later paper, there is no hiding it, also can carry out following control: standby dish 3 is kept open state, need not paper is temporarily discharged pile in standby dish 3, it is directly fallen provides to process disk 4.
If the paper P of pile reaches the regulation number of pages on the process disk 4, after the adjustment of having carried out longitudinal direction, transverse direction, form bookbinding sheet processed bundle T by attachment means 9.Afterwards, paper bundles T ties T by the driving of fore-and-aft adjustment roller 7, ink sprayer 10, bundle pawl band 11 along pile dish 13 direction conveyance of sheets, the rear end of paper bundles T is tied the bundle pawl 11a that is provided with on the pawl band 11 and is tangled, and is expelled on the pile dish 13, thereby the bookbinding processing of paper P finishes.
In addition, the paper number of pages that the paper number of pages of standby is more than four pages, carry out post-processing is more than five pages the time, carries out carrying with above-mentioned the 3rd page of same standby for the 4th page of paper getting final product.
According to present embodiment, when carrying out three pages of bufferings, on standby dish 3 with second page and the 3rd page stagger pile than first page more by rear end side, be the throughput direction upstream side, therefore, when the fore-and-aft adjustment on the process disk 4 of carrying out is thereafter handled, can be clipped in the adjustment of second page of paper between first page and the 3rd page reliably.Promptly, falling when the paper of pile in standby dish 3 is provided, the action by aftermentioned blade 5 makes the paper of topmost (the 3rd page) consistent with paper rear end location division 4a.On the other hand, by the counter-rotating of fore-and-aft adjustment roller 7 and distributing roller 12, carrying the paper of the bottom (first page) of pile on process disk 4 with discharge side in the opposite direction, and making it consistent with paper rear end location division 4a.As mentioned above, when adjust carrying the nethermost paper of the 10mm pile roughly of on sheet transport direction, staggering, about the paper (second page) of pile in the centre, even having produced along updrift side, departs from the pile on the standby dish, particularly owing to the friction drag between first page of paper and the paper, this second page of paper also can be transferred along with first page, thereby improves conformability.
In the above-described embodiment, stacking method for three pages of bufferings has been described in detail, but the paper process speed (discharge velocity) of image processing system and the post-processing speed of sheet post-process apparatus can be not what fix owing to various conditions change.Promptly, because the material of the difference of printing models such as single face/duplex printing, high fine pattern and printed medium and size is different, provide the pitch time of paper also different to sheet post-process apparatus.And sheet post-process apparatus also can be difficult to make regular time always post-processing time owing to material, material thickness and the handling of paper number of pages at the difference of the gutter pos of two position bookbindings of paper bight and end etc., medium.
So for handling property and the conformability that improves sheet post-process apparatus, increase and decrease buffering number of pages is more effective.
For example, after providing first page and second page of paper with low velocity from image processing system, even when having passed through to have passed through specified time after second page of paper and also not providing the 3rd page, if the processing on the process disk 4 finishes, two pages of paper that cushioning in the standby dish 3 are fallen in the process disk 4, the 3rd page of paper P is delivered to process disk 4 via standby dish 3 individually gets final product.Thus, improved the conformability on the process disk 4, performance can not reduce yet.On the other hand, even provide first page and second page of paper with low velocity, if the paper pitch time at the appointed time in, even also buffering in standby dish 3 of the 3rd page of paper owing to guaranteed the post-processing time, so can not cause the reduction of performance.
So the related sheet post-process apparatus of present embodiment comprises: control part can switch to the buffering number of pages in the standby dish 3 according to the standard print out rate of image processing system 200 and the processing speed of sheet post-process apparatus 100.Inlet roller 1 promptly, by providing speed synchronization to rotate with the paper that comes from image processing system 200, conveying is used for the paper P of post-processing, by being arranged at paper detecting sensor 26 detected paper pitch times on the transport path 26 when having surpassed specified time, based on the processing speed of carrying out post-processing on the process disk 4, the number of pages that the buffering number of pages of standby in the standby dish 3 is reduced to be no more than 3 pages (for example, two pages) is to guarantee the post-processing time.In addition, if from image processing system 200 at the appointed time with the interior paper that provides, and the post-processing on the process disk 4 do not finish, and then controls so that cushion number of pages and increase to more than three pages.About the paper pitch time of the multipage paper P by transport path 26, if by paper detecting sensor S26 instrumentation from the rear end that detects leading paper (for example, first page) by the elapsed time of beginning till the front end that detects down one page paper P.Like this, based on providing from image processing system, control to the buffering number of pages of standby dish 3, thereby can not cause the reduction of performance, can realize that the paper on the process disk is conforming stable to the paper pitch time of the paper of sheet post-process apparatus.
Mode (variation) as present embodiment, average treatment speed based on the paper pitch time of discharging conveying with the standard print out rate (for example, the single color printing speed of A4 size is 65 pages/minute) of image processing system 200 and each post-processing (classification and bookbinding are handled), set prescribed threshold by the paper pitch time of above-mentioned transport path 26, but, be not limited in this, suitably set the threshold values of buffering number of pages and paper pitch time as long as consider Combination property.
(not carrying out the situation of post-processing)
When not carrying out post-processing, for example, pile dish 13 slides and move to position shown in dotted lines in Figure 3, can conformability the paper P that from standby dish 3, discharges of pile well.For example, for using network institute's bonded assembly image processing system or carrying out a large amount of printing etc., will carry towards standby dish 3 by outlet roller 2 by the paper P that transport path 26 is delivered to outlet roller 2 from inlet roller 1.Then, paper P drops on the standby dish 3, is carried by live-rollers 14, and is discharged on the pile dish 13.
And, for not carrying out post-processing, and when the operator of image processing system duplicates etc. image processing system, as shown in Figure 3, as be easy to take out paper by way of, the paper P that carries from image processing system (direction of arrow) discharged 102 by roller, and pile is in paper bearing portion 103 via the transport path 101 that has diverged.
(second embodiment)
During till falling process disk at paper, make the formation of paper buffering, be not limited in the formation of above-mentioned standby dish 3.In the first embodiment, standby dish 3 tilted configuration in sheet post-process apparatus, pile is positioned on the position higher than the rear end at the top of form on the standby dish 3.Be directed to this, the related sheet post-process apparatus 101 of second embodiment forms formation shown in Figure 15.The related sheet post-process apparatus 100 of the basic comprising of sheet post-process apparatus 101 and first embodiment is identical, therefore, is that the center describes with distinctive difference.
As shown in figure 15, receive image processing system 101 by a pair of inlet roller 1 and implemented the paper that image forms, and this paper is offered a pair of outlet roller 2.Between inlet roller 1 and outlet roller 2, be formed with transport path.In the front and back of transport path, with the transport path arranged opposite paper detecting sensor S1, S2 are arranged, be used for detecting front end, the rear end of the paper of transport path.Near the paper detecting sensor S1 of inlet roller 1 side, be provided with the conveying that is used to switch paper by way of gate part G.A pair of outlet roller 2 roughly below, with the transport path almost parallel dispose paper bearing portion 300 as paper standby portion.Paper bearing portion 300 comprises: paper bearing platform 300a, rack pinion 306, paper bearing platform mobile motor 307.
Above the sheet transport direction downstream of paper bearing platform 300a, comprise by drive motor 302 rotations driving, with the swivel 14a that can pivotally supported mode with respect to axle 303 be supported.This swivel (after, be called live-rollers 14a) is configured to can be based on the action of drive source described later and lifting.Live-rollers 14a and nip roll 14b constitute live-rollers to 14, and this nip roll 14b and live-rollers 14a become a pair of.This live-rollers 14a on the position that descends, with paper by being pressed on the nip roll 14b.At the sheet transport direction upstream side of paper bearing platform 300a, dispose the clamp lever 3a of the rear end of the paper that is used to nip pile.Clamp lever 3a carries out following action: the rear end that keeps paper based on not shown solenoidal action, or decontrol the part that is kept.
Below, the stacking method of three pages of paper of pile describes in the subtend paper bearing portion 300, and this paper bearing portion 300 is provided with as the paper standby portion that makes the paper of carrying from image processing system carry out temporary transient standby.
Below, describe with reference to Figure 16, Figure 17 A to Figure 17 L.Figure 16 is illustrated in the situation when newly transporting first page of paper in the paper bearing portion 300.When promptly, newly transporting first page of paper P1, at this moment the state of the paper bundles T in the last handling process before being in pile in the process disk 4, forbids the discharge pile to process disk 4, carries out the paper buffering at paper bearing platform 300a.Be illustrated in the situation of pile to three page paper among the paper bearing platform 300a Figure 17 A to Figure 17 L model utility.
At first, when the front end of the first page of paper P1 that discharges from outlet roller 2 is transported near the live-rollers 14a, make live-rollers open and close magnet (not shown) action, make live-rollers 14a rise to hoisting position along ascent direction.This is to meet live-rollers 14a (with reference to Figure 17 A) for the front end of the first page of paper that prevents to transport.At this moment, live-rollers 14a rotates along throughput direction.With paper P1 be delivered to live-rollers 14a roughly under after, make live-rollers 14a along D direction descend (with reference to Figure 17 B).
Because live-rollers 14a rotates along throughput direction, so, further carry itself and the paper P1 of nip roll 14b clamping, and finish to discharge from outlet roller 2, thus with paper integral body pile in paper bearing portion 300.Simultaneously, the stop operating rotation (with reference to Figure 17 C) of roller 14a.
After pile, live-rollers 14a is reversed about several pulses (for example, 1～5 pulse), transfer paper feeding last time at the paper rear end side end direction of paper bearing platform 300a and open P1.Then, make actions such as o ES, clamp lever 3a is rotated along arrow Q direction, the pile (with reference to Figure 17 D) of first page of paper in paper bearing portion 300 finished in the rear end that keeps first page paper P1.Revolution is carried in order to ensure the paper rear end keeps (clamping) amount and is carried out.
Then, when the front end of second page of paper P2 is delivered near the live-rollers 14a, make live-rollers open and close the magnet action, make the live-rollers 14a that first page of paper clamp is held in the paper bearing portion 300 rise to hoisting position.In addition, under this state, rotary electric machine is just changeed, along throughput direction rotation (with reference to Figure 17 E).Even this is to have met live-rollers 14a for second page of paper, paperboard can not take place yet.At this moment, keep the rear end of first pile in first page of paper P1 of paper bearing portion 300 by clamp lever 3a, and, though live-rollers 14a rotate along throughput direction,, because it is in hoisting position, so, can not carry first page of paper.
Afterwards, discharging second page of paper P2 from outlet roller 2, and before pile in the paper bearing portion 300 finishes, top of form passes through paper detecting sensor S2 afterwards through behind the specified time, the paper rear end of first page the paper P1 that relieving clamp lever 3a is kept, and, arrive the assigned position on the throughput direction upstream side of first page of top of form with the front end of second page of paper P2, the for example timing of position of staggering 10mm with the front position of first page of paper, the live-rollers 14a that remains in hoisting position rotates to throughput direction, makes it along arrow D direction decline (with reference to Figure 17 F).
By this action, under the state (on throughput direction, first page of top of form is leading than second page of top of form) that keeps first page of paper P1 and second page of paper P2 to stagger, carry two pages of paper in front.Calculate to carry the pulse of the pulse motor PM of second page of paper P2, become the timing of 10mm, live-rollers 14 in the rotation is descended and nip with the difference of the front end of two pages of paper.To the rear end of second page paper P2 from outlet roller to 2 discharge finish till, by live-rollers 14a with first page of paper P1 and second page of paper P2 simultaneously downstream carry (with reference to Figure 17 G).
After the discharge of end by the paper P2 of outlet roller 2, the rotation of roller 14a stops operating, make outlet roller 2 several pulses of counter-rotating, about the paper rear end, after two pages of paper P1, P2 are carried in the revolution of the paper rear end side of paper bearing platform 300a and first page of rear end (with reference to Figure 17 H) that similarly keeps second page of paper P2 by clamp lever 3a.
As mentioned above, the top of form portion of two pages of paper that stagger in the holding position and paper rearward end, the pile that carries out in paper bearing portion 300 finishes.
Below, when the front end with the 3rd page of paper P3 is delivered near live-rollers 14a, make live-rollers open and close the magnet action, be used in first page, second page paper risen to hoisting position by the live-rollers 14a that is pressed in the paper bearing portion 300.Under this state, rotary electric machine is just changeed, make live-rollers 14a along throughput direction rotation (with reference to Figure 17 I).
At this moment, because clamp lever 3a keeps the rear end of first pile in first page, second page paper of paper bearing portion 300, and though live-rollers 14a rotates along throughput direction, it is positioned at hoisting position, so, can not carry first page, second page paper.
When discharge and before pile in the paper bearing portion 300 finishes from outlet roller 2 rear end of the 3rd page of paper P3, promptly, by calculate driving the pulse of outlet roller to 2 pulse motor PM, at the roughly overlapping moment of front end of front end and the 3rd page of paper P3 of second page of paper P2, stop pulse motor PM.In addition, when decontroling clamp lever 3a, make the live-rollers 14a that is positioned at hoisting position under the state that rotates along throughput direction, along arrow D direction decline (with reference to Figure 17 J).At this moment, because live-rollers 14a rotates along throughput direction, therefore, with paper sheet delivery side downstream, still, and through after several pulses, the rotation of the roller 14a that stops operating.
By this action, under the situation that the staggered positions that does not change first page and second page concerns, the 3rd page of paper P3 is overlapping in the mode of aliging with the front position of second page of paper on second page of paper P2.
The pile amount of staggering of three pages of paper in paper bearing portion 300 is: first page of paper is positioned at the leading position in the downstream of throughput direction, and second page, the 3rd page is positioned at from this position upstream that side staggers on the position of 10mm roughly.With this position relation, each paper is carried out paper sheet delivery (with reference to Figure 17 K) when being pressed in the paper bearing portion 300 by live-rollers 14a.
After the discharge of paper P3 finishes, the rotation of the roller 14a that stops operating, counter-rotating live-rollers 14a turns round conveying and stops.In paper bearing portion 300, with the state that staggers in the position that keeps above-mentioned front end, pile three pages of paper (with reference to Figure 17 L).In addition, making the 4th page follow-up paper that transports also during standby, get final product to handle with the identical process of pile of above-mentioned the 3rd page of paper.
Below, the paper that makes pile in the paper bearing portion 300 is fallen the processing that is provided to process disk 4 describe.Figure 18 A to Figure 18 C is used for the explanation of model utility ground situation about providing is provided.
If mobile fully paper bearing platform 300a, then three pages of paper are because deadweight, thereafter distolateral meeting hang down (with reference to Figure 18 B).
In addition, make live-rollers 14a switch to hoisting position, decontrol the clamping of paper, then be disposed at paper bearing portion 300 below process disk 4 on, three pages of paper begin land from the paper rear end of hanging down, on process disk 4, slide, and consistent with the paper rear end location division 4a of process disk 4.When paper falls, blade 305 is rotated, carry out the adjustment (with reference to Figure 18 C) of paper topmost.Therefore, since fall the paper that provides to the process disk 4 be from paper rear end land on process disk 4, so the vertical consistency on the process disk 4 is good.And, when continuing to transport the 4th page or the paper that do not need to cushion, paper bearing platform 300a is resetted in live-rollers to 14 side original positions, as mentioned above, by live-rollers to the follow-up paper of 14 clampings, and make paper bearing platform 300a move to outlet roller 2 sides (with reference to Figure 18 A), paper is fallen to be provided to process disk 4.In addition, when the vertical consistency that carries out bottom (first page) paper of pile in process disk 4 is adjusted, can obtain the effect identical with first embodiment.
In addition, in the present embodiment, to guarantee before keeping in the rear end that the rear end keeps (clamping) amount is purpose, having carried out revolution carries, but, there is no hiding it, even in the time can realizing also under the situation of not turning round conveying that by the geomery of suitably selecting clamp lever 3a the rear end keeps, can omit revolution and carry.In addition, in the present embodiment, the paper bearing platform 300a of paper bearing portion 300 is horizontally disposed with, but, also can be according to the height and position of the paper discharge portion of image processing system 200, the inlet roller 1, the configuration of outlet roller 2 of change sheet post-process apparatus 101 are positioned at the mode of the position lower than top of form, tilted configuration paper bearing portion 300 with the rear end side of paper.In addition, in second embodiment of the present invention, for handling property and the conformability that improves sheet post-process apparatus 101, the paper pitch time based on regulation increases and decreases also very effective to the buffering number of pages of paper bearing portion 300.
(the 3rd embodiment)
By making the paper process high speed in the sheet post-process apparatus, the carried charge of paper increases, and for example paper can have viscous force when carrying on the standby dish 3 or falling on process disk, has the possibility that does not move to the anticipation position.
Imappropriate in the last handling process requires the paper of pile on standby dish 3 not charged.So preferred paper will remove reliably via before the standby dish 3.
As mentioned above, in order to adapt to having or not or the content of post-processing of post-processing, in the related sheet post-process apparatus of present embodiment, a plurality of paper transportation path have been prepared.Which in addition, preferably no matter via path, before the paper pile is in standby dish 3, can remove reliably.
Below, describe removing electric parts with reference to Figure 19.As shown in figure 19, in the downstream of outlet roller 2, dispose as the paper bias arm 16 that can switch with the paper application of force unit (biasing means) of the butt state of paper.Paper bias arm 16 performance acts on the conveying of the paper that transports out from outlet roller 2 more smoothly.Paper bias arm 16 is formed by electroconductive component (for example, corrosion-resistant steel panel).Paper bias arm 16 can rotate along the above-below direction of arrow A by cam following arm 17, and this cam following arm 17 is cam-driven by the rotation driving of sub-arm motor 19 shown in Figure 19.
And, on an end in the throughput direction downstream that is positioned at this paper bias arm 16, be equipped with and remove electric parts 15.Preferably removing electric parts 15 is STAINLESS STEEL WIREs of rubbing superfine footpath, and makes it become the brush shape to form.In addition, standby dish 3 is positioned at the below of paper bias arm 16.
When paper by outlet roller 2 clampings and carry, charged by friction.So the paper that transports out from outlet roller 2 is directed to paper bias arm 16, paper with remove electric parts 15 and contact in, conveyance of sheets.
Below, action during to pile paper on standby dish 3, paper bias arm 16 describes.By making 19 rotations of paper sub-arm motor, make cam (not shown) rotation, and cam following arm 17 is shaken.By shaking of cam following arm 17, paper bias arm 16 rises and rotates along the direction of arrow that makes progress among Figure 19.In addition, utilize cam sensor crack 18 to detect the spin angular position of cam.
Constituting rotary paper bias arm 16 stops except that electric position, these three positions of (3) pressing position in (1) position of readiness, (2).Position of readiness is the position of the top, and till top of form arrival live-rollers 14, paper bias arm 16 is positioned at this position of readiness.Removing electric position is midway location, and when not needing to carry out the straight line row paper of post-processing, paper bias arm 16 is positioned at this and removes electric position.
Pressing position is the position of below, and when standby dish 3 pile paper, when paper rear end during by outlet roller 2, paper bias arm 16 moves to this pressing position.When the paper pile is on standby dish 3, with paper by being pressed on the standby dish 3 to prevent paper come-up, confusion.
As mentioned above, after pile finishes on standby dish 3, standby disk-drive motor (not shown) is just changeed, standby dish 3 is moved along the transverse direction of paper is open, make blade 5 actions, and paper is fallen to process disk 4.Standby dish 3 is when opening with the direction of throughput direction quadrature, and by removing the lower part of electric parts 15, auxiliary paper falls.
According to present embodiment, can be with the posture of arbitrarily angled maintenance paper bias arm 16, can carry out corresponding widely at the classification information of the paper that for example transports from image processing system.Even in the paper sheet delivery process, also can change the posture of paper bias arm, therefore, can be corresponding to the state of paper.And, can not exist with ... paper sheet delivery by way of, make reliably and remove electric parts and paper friction, to remove.
(the 4th embodiment)
Below, to paper from standby dish 3 when process disk 4 falls, be used to pat the blade that paper carries out fore-and-aft adjustment and describe.
Figure 20 is the scheme drawing that transverse observation arrives blade 5.The following effect of blade 5 performance: the paper of pile in the standby dish 3 is fallen on the process disk 4 (in the present embodiment, be called initiatively and fall) time, by patting the paper rear end, prevent to fall the at random of paper in the process, and make and clap the paper that falls and on process disk 4, carry out fore-and-aft adjustment as soon as possible.Therefore, in order to improve performance, need high speed revolution.
So the sounds of the wind the when impulsive sound when patting paper in order to reduce and the impetus are rotated well etc. in the present embodiment, are suitably controlled the rotation of blade 5.
As shown in figure 20, blade 5 comprises: spool 20, and it is that axle is bearing in the swivel on the blade S. A. 22; Be installed in the short blade P1 of length on the spool 20; And the long blade P2 of length.Even also do not damage paper for contact paper P surface, blade P1 and blade P2 are elastic body and constitute.By short blade P1, can clap paper to process disk 4 from standby dish 3.In addition, by long blade P2, can paper carries out fore-and-aft adjustment in the process disk 4 to falling.In addition, the blade 5 that is disposed is not limited in one, and the size according to the paper of handling also can separate predetermined distance and be arranged side by side a plurality of blades.In the present embodiment, be provided with blade P1, P2 totally two blades.
By the pulse management of paddle motor, rotation drives the blade 5 that so constitutes.At first, paddle motor is just changeed, drive transmitting to blade S. A. 22, is made spool 20 rotations.
Figure 21 be used for illustrating blade 5 rotary course temporarily stop control.
Calculate the pulse of paddle motor, the angle of rotation of control blade S. A. 22, by short blade P1 from standby dish 3 after process disk 4 claps paper, the rotation of blade 5 is temporarily stopped.Promptly, as shown in figure 22, the rotation of blade 5 is temporarily stopped on the position that maintains predetermined distance Q2 between paper surface on the process disk 4 and the long blade P2.The number of pages of the paper of pile changes according to the content of the post-processing of user's setting on the process disk 4, still, owing to be other calculating, so the predetermined distance Q2 here only is the distance that long blade P2 does not contact paper surface.Interval Q1 between short blade P1 and the paper surface is controlled to be the relation of Q1≤Q2, still, if the pile of paper P increases, then is 0≤Q1＜Q2.Like this, not contacting at long blade P2 on the position of paper surface, the rotation of blade 5 is temporarily stopped, is the fore-and-aft adjustment for not overslaugh fore-and-aft adjustment roller 7.And, by temporarily stopping, can alleviating the noise that high speed revolution produced of following blade 5.
After temporarily stopping, for example behind process number msec, in the fore-and-aft adjustment process of fore-and-aft adjustment roller 7 rotations, carry out the rotation of blade 5 once more.Based on this action control,, the paper of falling on the process disk 4 is caused the inside of process disk 4, thereby carry out fore-and-aft adjustment reliably by long blade P2.
Below, the timing of paper sheet delivery and blade action is described.Show the conveying track of top of form on process disk 4 Figure 22 model utility.In addition, Figure 23 is used to illustrate the instruction diagram that concerns between the front position of the ON/OFF control of blade rotation action and paper.In Figure 22 and Figure 23, A represents that than outlet roller 2 more by carrying the position of upstream side, B represents the front position of the paper on the standby dish 3, and C represents the top of form position on the process disk 4, and D represents for example gutter pos.
By supply unit paper is carried to position B from position A, paper fall pile on standby dish 3 after, the drive vane motor.As mentioned above, by this action, short blade P1 claps paper and falls on the process disk 4.In addition, paper moves to position C from position B.When long blade P2 turned to the position that does not contact the upper sheet surface on the process disk 4, blade S. A. 22 stopped paddle motor.In this action, the paper on the process disk 4 begins to move based on inertia from the position that can bind of position C towards position D.When the paper on the process disk 4 arrive can fore-and-aft adjustment the position time, begin the paddle motor action once more.As shown in figure 23, this a series of action is by the process that moves to position C from position B, move to the process of position D from position C, and the rotational action of ON control blade 5 realizes.
Paper about pile on process disk 4 applies fore-and-aft adjustment power, and the paper of upside is to depend on beating in of blade 5, and downside then is to depend on fore-and-aft adjustment roller 7.Therefore,, adjust first page of paper with inversion driving fore-and-aft adjustment roller 7, paddle motor is just being changeed by second page of blade 5 fore-and-aft adjustment, the 3rd page of paper by making the counter-rotating of fore-and-aft adjustment motor about the paper of the pile that on standby dish 3, staggers.
In addition, by the first page of paper that has applied stable fore-and-aft adjustment power by fore-and-aft adjustment roller 7 is positioned at than second page, the 3rd page more by on the staggered positions in throughput direction downstream, can utilize the friction of paper, first page fore-and-aft adjustment power is put on second page and then the 3rd page of paper.
As mentioned above, by a spinning movement of blade 5, can realize conveying and the fore-and-aft adjustment of paper to process disk 4.
According to present embodiment, can reduce the impulsive sound of patting paper.In addition,, make the blade rotation number be reduced to once rotation, therefore, can provide paper at high speed, do not influence the post-processing time, can have enough leeway to adjust from image processing system by before the once rotation of blade 5, temporarily stopping.
(the 5th embodiment)
In the time of blade 5 such turning units will being snapped in S. A., generally speaking, on S. A., form groove, in this groove, insert pin.Therefore, between groove and pin, need be accompanied by the gap of size, thereby shakiness can take place.Therefore, the turning unit that rotating blade 5 is such when patting paper, can take place to impact or vibration, produces noise.Though attempted reducing the tolerance between groove and the pin as far as possible,, on making, there is restriction.
So, in the present embodiment, the formation that employed parallel pin can not be touched in the rotational action of blade 5 when having adopted the buckle turning unit.
Below, with reference to Figure 24 to Figure 26, the situation of the spool 20 that uses parallel pin 23 buckle blades 5 is described.
Figure 24 be the expression buckle block diagram of spool 20.As shown in figure 24, the central portion at spool 20 is through with S. A. 22 loosely.In S. A. 22, the mode in axle center connects to pass roughly in parallel pin 23.At the central portion of spool 20, be formed with the groove 24 that is used to embed parallel pin 23.In addition, in the inside of groove 24, form two place's projections 21.The shape of projection 21 for example is the mountain type.
Figure 25 shows the relation of parallel pin, S. A., spool portion groove etc.
As shown in figure 25, set the size of the spool portion groove 24 of spool 20, so that the mode that the center C 2 of the center C 1 in the hole of S. A. 22 and spool portion groove 24 staggers forms spool portion groove.For example parallel pin 23 is Φ 2, and is stainless steel.Spool portion groove 24 and spool portion projection 21 form with spool is whole, are resin mold (mold) system.The material of S. A. 22 for example is a quick-turning steel.
As parallel pin 23, select than the harder material of spool portion projection 21 intensity that is formed in the spool portion groove 24.
Size till from the top 21a of projection 21 to the long limit of spool portion groove 24 for example is 1.87 ± 0.3mm less than the external diameter of parallel pin 23.
In such formation, along on the side on the long limit of the spool portion groove 24 of spool 20 thruster of parallel pin 23 being gone into to rotate in the axis hole, to insert parallel pin 23.Thus, the projection 21 that is formed in the spool portion groove 24 is crushed, thereby parallel pin 23 shakiness can not take place.With the fwd example, begin to crush about 0.13mm from the top 21a of projection 21.
Applying method for the power that puts on above-mentioned parallel pin 23 describes.As Figure 25 and shown in Figure 26, with parallel pin 23 by the side that is pressed in spool portion groove 24, on the other hand, the two place's projections 21 of crushing.Thereby, in parallel pin 23,, act on P ', the P ' external force of identical size from the side from the external force of projection 21 effect P, P.Therefore, the power that acts on parallel pin 23 can balance, thereby can eliminate shakiness.
Like this, owing to and parallel pin between shakiness have on the position that the noise worry takes place, can be not limited to blade.
According to present embodiment, can manage the tolerance of tolerance, S. A. and the spool of S. A. and parallel pin loosely, therefore, the manufacturing of these parts is worsened, can realize that the failure-free gap inlays.In addition, because parallel pin can not touched, can reduce chatter.
