Description
Technical field
The present invention relates to a kind of sheet folding apparatus that is used for folding page or leaf shape recording medium, a kind of have a sheet processing apparatus this sheet folding apparatus and by saddle stitching bookbinding or similar bookbinding, and a kind ofly have the such sheet folding apparatus or the imaging device of sheet processing apparatus, for example photoprinter (photocopier), chopping machine, facsimile equipment and a printer.
Background technology
In imaging device, for example in photoprinter, chopping machine, facsimile unit and the printer, image passes through developer, toner for example, for example photoelectric conducting drum or photoconductive band develop and form to make latent image carrier, and this image is transferred on the recording medium and (for convenience's sake, after this is referred to as paper or page or leaf).
Except only export from imaging device one individual be formed with image the page or leaf situation, also there is such situation, the a plurality of page required numbers according to duplicte with image form folded and ordering, and fastening and bookbinding by clasp machine, then from imaging device output, a kind of page of after-treatment device or collator can be used as such device.
Utilize such page or leaf after-treatment device, accept by the bevelled telophragma in turn from the page or leaf of imaging device output, by hitting the alignment of paper baffle plate (jogger fence) or analogue, and align by being pressed on stop portion or the analogue by the end edge of record page that slips into the lower end side of telophragma on Width for the end edge of page or leaf.Then, the end edge of page or leaf is bound processing by a clasp machine, and stacked page or leaf group (sheet group) outputs to output panel.
Japanese patent application H8-137151 once proposed a kind of like this structure in communique, this structure is provided with one and is used to take out the lower end of page or leaf and delivers to bluff piece on the load-transfer device, this used for conveyer belt in conveying be contained in the telophragma the page or leaf, this structure combines the taking-up of page or leaf with the mobile phase of load-transfer device, and carry the position of such page or leaf, thereby stacked page or leaf group is outputed to output panel after handling through such bookbinding to outlet roller.
Simultaneously, method as a kind of page of post-processing, except above-mentioned bound the method for processing with clasp machine in the end edge of page or leaf, for example, also have saddle stitching (saddle stitching) method wherein the end edge of page or leaf do not bound, the central part of the output page on outbound course is bound, and Japanese patent application NO.2001-19251, NO.2001-206629 and NO.2002-167120 have also proposed a kind of middle method for folding that folds page or leaf in the saddle stitching position in communique.
Incidentally, structure at the page or leaf after-treatment device that is used for the bound pages end edge, be used to prevent the bookbinding pinch device that end edge is outstanding, the auxiliary conveying revolving part that can compress page frame table (transport auxiliary rotative member) that promptly has a fin is arranged on the position in the face of clasp machine, in other words, be in the position of conflicting with the end edge of the page or leaf that slips into towards clasp machine, thus the bad conveying of page or leaf when preventing that end edge when bound pages is unsteady.
Yet, when carrying the page or leaf of handling through bookbinding once more, though the end edge of page or leaf is alignd by hitting the paper baffle plate on Width, but because end edge is taken out by claw component (pawl member), just, the end edge of the rear side on the page or leaf throughput direction (after this abbreviating " back edge " as) only is in a such state, promptly be supported on the inner bottom surface of claw component, the back edge of page or leaf since page number become with respect to the size of holding the gap of inner bottom surface and do not line up.Especially, when by saddle stitching or middle folding the bookbinding, if the back edge of page or leaf becomes do not line up, not lining up of the end edge that page or leaf is folded becomes after bookbinding obviously, and finally causes a relatively poor outward appearance.
Simultaneously, utilization has the sheet processing apparatus of this saddle stitching or middle folder function (saddle stitching or middlefolding function), the folded centre of page or leaf folds by partly carrying out with the folded bookbinding of folded sheet (folding plate) extruding page or leaf, wherein the folded centre portion of page or leaf is bound, and by producing a fold line through a pair of folding roller that is arranged on the folded moving direction of page or leaf.When utilizing the bookbinding of this saddle stitching, the folding position of folding roller and gutter pos overlap exactly and can to tilt alignedly be crucial in the folding position, this while also is user's strong request.
Therefore, in order to satisfy this requirement, for example Japanese patent application NO.2001-206629 discloses a kind of structure, its alignment page or leaf folded (sheet bundle), two enterprising luggages in position on page width degree direction are ordered processing then, the forward edge of further hooking folded sheet arrives binding needle, and it is pressed in the 5165 folding roller roll gaps.In addition, Japanese patent application NO.2002-167120 discloses a kind of structure, in order to determine the folding position, has stop portion on throughput direction, and have transportable aligning apparatus on Width.
Yet for the structure in these background technologies, the position that does not line up is on existing, therefore to have such situation in theory because fold line will become, and promptly fold line will become in practical operation and not line up.This situation be because to cut into standard-sized page or leaf be not rectangle accurately.

(3) sorting/pile up pattern:
Carry out and identical conveying and the output function of nothing bookbinding Mode B.Therefore, output page is by transfer table 202 sortings, and this transfer table 202 is swung on the direction perpendicular to the outbound course of each separative element.
(4) operation of stapling mode:
The page or leaf from transport path A by path selector 15 and path selector 16 sortings is directed to transport path D, and outputs to bookbinding process disk F by conveying roller 7, conveying roller 9, conveying roller 10 and bookbinding outlet roller 11.In bookbinding process disk F, the page or leaf that reaches a predetermined number is bound processing in turn from the page alignment of outlet roller 11 outputs, and by end face bookbinding clasp machine S1.After this, institute's bound pages folded (bund sheet bundle) is transported to downstream (anterior downstream on the direction of transfer table 202) by discharging pawl 52a, and outputs to transfer table 202 by shifting outlet roller 6.In addition, be arranged on and shift the oral instructions sensor 303 that migrates out that near the being used to outlet roller 6 detect page or leaf output and be used to detect output state.
(5) operation of saddle stitching stapling mode:
In this pattern, the page or leaf that carries out center bookbinding (center binding) processing by the clasp machine S2 in the stapling mode is transferred via following treating process.In other words, movable guide piece 55 is arranged on an acceptable state, by the pressure roll 57 of branch's guide plate 54 and contacting with each other of outlet roller 56, thereby folding process disk G in the middle of when page or leaf wedging outlet roller 56 and pressure roll 57, being directed to, the page or leaf leading section against movably the back end-stopping plate 73, when page or leaf is positioned at the center gutter pos, under the combined action that folded sheet 74 stretches out, page or leaf is folded between the roll gap of folding roller 81, in time export lower disc 203 to, the position of the folded sheet 74 that folding process disk G was equipped with in the middle of wherein said center gutter pos was positioned at the folding back page or leaf of finishing dealing with by outlet roller 83.At this, page or leaf is laminated to the folding unit that reaches sensor 321 and be positioned at outlet roller 83 front portions by the page or leaf that is positioned at folding roller 81 front portions and detects by sensor (folding unit passage sensor) 323, therefore, the rotation fixed-time control of the running contact of folding roller 81 and fixed-time control and outlet roller 81 can be set.
Then, the output state of the page or leaf in aforesaid stapling mode and the saddle stitching stapling mode is described with reference to Figure 15, Figure 16 A to 16D and Figure 17 A to 17D.
Figure 15 is the bookbinding process disk F shown in Figure 3 and the enlarged view of the structure of middle folding process disk G.
In Figure 15, whether page or leaf imports bookbinding process disk F exists monitoring device (sheet existencemonitor) 310 monitorings by page or leaf, branch's guide plate 54 is in so a kind of state, wherein pressure roll 57 is away from outlet roller 56, and output is positioned at by discharging on the position that pawl home sensor 311 detects with 52 discharge pawl 52a.
When selecting stapling mode, at first, the paper baffle plate 53 of hitting described in Fig. 8 moves from reference position, and goes up at standby position (standby position) and to wait for that this standby position is positioned on the 7mm that outputs to page width degree one side on the bookbinding process disk F.When page or leaf is carried by bookbinding outlet roller 11 and the rear end of page or leaf through bookbinding outlet sensor 305, hit paper baffle plate 53 and move from standby position and move inward 5mm and stop.In addition, when the rear end of page or leaf through out-of-date, bookbinding outlet sensor 305 detects this signal, this signal is input to CPU 360 (with reference to Figure 14 A and 14B) then.The unshowned pulse that CPU 360 countings carry motor 155 to transmit from bookbinding, be used for when bookbinding outlet roller 11 receives this signal, driving bookbinding outlet roller 11, and after the pulse that transmits a predetermined number, open location screw actuator (SOL) 170 (with reference to Fig. 7).
When location screw actuator (SOL) 170 cut off and through a specific time after, hit paper baffle plate 53 by hitting paper motor 158 and move inward 2.6mm and then stop, thereby finished the sidepiece alignment.Then, hit paper baffle plate 53 outside mobile 7.6mm and turn back to standby position, wait for next page or leaf.This operation continues until last page or leaf.Then, hitting the paper baffle plate moves inward 7mm once more and compresses the folded both sides of page or leaf and handle for bookbinding and prepare.
After a specific time, end face bookbinding clasp machine S1 binds processing by unshowned bookbinding motor.At this, when two or more gutter pos of design, after the bookbinding of a position was finished dealing with, bookbinding mobile motor 159 (referring to Figure 10) was driven, end face bookbinding clasp machine S1 moves to a suitable position along the rear end of page or leaf, then carries out the bookbinding of the second place and handles.In addition, when the 3rd position or more position were used to bind, above-mentioned processing repeated.
When bookbinding is finished dealing with, drive output motor 157 (referring to Fig. 8), drive output and be with 52, at this, output motor is driven equally, is used to accept begin rotation by discharging the folded transfer outlet roller 6 of pawl 52a taking-up page or leaf.
Hit paper baffle plate 53 and can have different control according to the number of page or leaf size and bound pages.For example, when the number of bound pages is less than when setting number, when perhaps size was less than the size set, hitting paper baffle plate 53, to hold down page or leaf folded, discharges simultaneously that pawl 52a will hook the folded rear end of page or leaf and conveying of sheet is folded.
In bookbinding process disk F,, after the pulse of a regulation, recall the bookbinding that 2mm unclamps page or leaf thereby hit paper baffle plate 53 according to existing sensor 310 or output to take up the detection of beginning position transduser 311 at the page or leaf shown in Figure 15.The pulse of this regulation is arranged between the process of the rear end of discharge pawl 52a contact page or leaf and the front edge that process is hit paper baffle plate 53.
In addition, when the number of bound pages greater than the size of setting number or page or leaf greater than the size of setting, hit paper baffle plate 53 and at first recall 2mm, thus output page.Under each situation, when the folded process of page or leaf is hit paper baffle plate 53, hit paper baffle plate 53 outside mobile 5mm and turn back to standby position, for next page or leaf is prepared.Incidentally, to regulate bookbinding power be possible equally according to hitting paper baffle plate 53 to the distance of page or leaf.
Figure 16 A to Figure 16 D and Figure 17 A to Figure 17 D show the page or leaf output state in above-mentioned saddle stitching stapling mode.When selecting this pattern, the page or leaf from transport path A by path selector 15 and path selector 16 sortings is directed to transport path D, and outputs to bookbinding process disk F by conveying roller 7, conveying roller 9, conveying roller 10 and bookbinding outlet roller 11.
In bookbinding process disk F,, the page or leaf (referring to Figure 16 A) that arrives a predetermined number is bound processing in turn from the page alignment of outlet roller 11 outputs, and by end face bookbinding clasp machine S1 as aforesaid stapling mode.In other words, only carry out registration process, the end face bookbinding is handled and is not carried out.Therefore, shown in Figure 16 B, page or leaf is folded by discharging pawl 52a and is carried a distance of stipulating downwards according to the size of each page, and processing is bound by saddle stitching clasp machine S2 in the center of page or leaf.The folded size according to each page of the page or leaf of bookbinding passes through to discharge the distance of pawl 52a downstream transport regulation, stops once more in the position shown in Figure 16 C.This miles of relative movement is by the drive pulse control of output motor 157.
After this, shown in Figure 16 C, between the wedged outlet roller 56 of front end and pressure roll 57 that page or leaf is folded, and enter a state to a path movement, i.e. rotation by branch's guide plate 54 and movable guide piece 55 is folding process disk G in the middle of the folded guiding of page or leaf, and by discharging pawl 52a and outlet roller 56 downstream transport once more.Outlet roller 56 is arranged on output with on 52 the axle drive shaft, thereby is with 52 by driven in synchronism with output.
And, shown in Figure 16 D, page or leaf is folded to be delivered to movable back end-stopping plate 73 by folded conveying roller (upper bundle transportroller) 71 of upper page and the folded conveying roller (lower bundle transport roller) 72 of lower page, and this baffle plate is used for the end face of the folded bottom of page or leaf is moved forward to a position from reference position according to the size of page or leaf.At this, discharging pawl 52a stops on the position, be arranged on this position output discharge with on the opposed locations of 52 neighborings another pawl (this ratchet is represented with Reference numeral 52a ' in Figure 16 D for convenience's sake) arrive back end-stopping plate 51 near, distraction guide 54 and movable guide piece 55 turn back to reference position and prepare for next page.
In Figure 17 A, the folded pressure owing to the folded conveying roller 72 of lower page of page or leaf that is crushed on the end-stopping plate 73 of movable back unclamps.After this, shown in Figure 17 B, near the plate 74 that is folded on the direction of approximate vertical of binding needle compresses, and in the folded roll gap that is directed to the folding roller 81 that is positioned at the sidepiece that folded sheet 74 stretches out of page or leaf.Folding roller 81 is by pressurization and carry the folded folded center of page or leaf that folds of this page.
In Figure 17 C, when the folded leading section of fold page or leaf was detected by sensor 323 by folding unit, folded sheet 74 turned back to reference position.After this, shown in Figure 17 D, page or leaf is folded to output to lower disc 203 by bottom outlet roller 83.At this, when the folded rear end of page or leaf no longer is laminated to when reaching sensor 321 and detecting by page or leaf, movable back end-stopping plate 73 turns back to reference position, the pressure recovery of the folded conveying roller 72 of page or leaf, and prepare for one page down.In addition, if next task is same page or leaf size and same number of page or leaf, movable back end-stopping plate 73 can be waited on this position.
In this embodiment, when selecting each output mode of aforementioned page or leaf, in control unit 350, carry out corresponding to the processing of this pattern.
Figure 18 to Figure 22 is a diagram of circuit, and the control in the control unit 350 is described, Figure 18 and Figure 19 show does not have bookbinding Mode A and B; Figure 20 shows sorting/pile up pattern; Figure 21 shows stapling mode; Figure 22 shows the saddle stitching stapling mode.
In Figure 18, when selecting arming to order Mode A, use following control content.Incidentally, below in Shuo Ming the control, page or leaf is interpreted as paper, consistent among the Reference numeral of each parts and Fig. 3.
When paper when imaging device is carried, be positioned at the inlet roller 1 on the transport path that wherein is provided with driling unit 100, the conveying roller 2, conveying roller 3 and the top outlet roller 4 that are positioned on transport path A, the B of upper disc 201 begin rotation (S101) respectively.Then, determine the opening (S102) of inlet sensor 301, and, when inlet sensor 301 is opened, determine whether inlet sensor 301 cuts off (S103).
At definite top outlet sensor 302 (S104, S105) unlatching/cut-out and during according to the number of pages order of aforesaid each step counting process, if determine that last paper is through (S106), through behind the specific time, the rotation of inlet roller 1 and conveying roller 2,3 and top outlet roller 4 stops (S107) so.
Therefore, all pages or leaves from imaging device are not exported and are loaded on the upper disc 201 in bookbinding ground.
Incidentally, the paper that comes from imaging device can obtain perforation and handle through driling unit 100 time, and can output on the upper disc 201 with the state of the perforation of needs.
Then, do not describe there being the bookbinding Mode B with reference to Figure 19 A and Figure 19 B.
When paper when imaging device is carried, be positioned at inlet roller 1, conveying roller 2 on the transport path that wherein is provided with driling unit 100, be positioned at the conveying roller 5 on the transfer table transport path C and shift outlet roller 6 and begin rotation (S201) respectively.Then, be used to drive the screw actuator unlatching of path selector 14 and path selector 15, path selector 14 inhour rotations, path selector 15 clickwises (S202).
Determine the opening (S203) of inlet sensor 301, when this inlet sensor 301 is in unlatching, determine whether inlet sensor 301 cuts off (S204), determine to migrate out the opening (S205) of oral instructions sensor 303, determine to migrate out oral instructions sensor 303 and whether cut off (S206), the number of the conveying of sheet of confirming process and determine last page or leaf through after (S207), after a specific time, inlet roller 1 on the transport path and conveying roller 2, and the conveying roller on the transfer table transport path 5 and the rotation of shifting outlet roller 6 stop (S208), and the screw actuator that is used to drive path selector 14 and path selector 15 cuts off (S209).
As a result, all pages or leaves that import from imaging device can be output and be loaded on the transfer table 202 with not binding.Incidentally, similarly under this pattern, the page or leaf of process driling unit 100 can be subjected to perforation and handle before output.
Then, with reference to Figure 20 A and Figure 20 B sorting/the pile up control of pattern is described.
When paper will be when imaging device be carried, the conveying roller 5 in the middle of inlet roller 1 on the perforation transport path and conveying roller 2, the transfer table transport path C and shift outlet roller 6 and begin rotation (S301) respectively.Then, be used to drive the screw actuator unlatching of path selector 14 and path selector 15, path selector 14 inhour rotations, path selector 15 clickwises (S302).
Determine the opening (S303) of inlet sensor 301, determine whether inlet sensor 301 is cut off (S304), determine to migrate out oral instructions sensor 303 and be in opening (S305), determine whether the paper part through migrating out oral instructions sensor 303 is top sheet (S306).
If paper is not a top sheet, because transfer table 202 moves, paper is output so.If paper is a top sheet, shift motor 169 (referring to Fig. 5) and open (S307), transfer table 202 moves on perpendicular to the direction of page or leaf throughput direction, detects transfer table 202 and opens this transfer sensor 336 (S308) up to shifting sensor 336 (referring to Fig. 5).
By detecting the transfer sensor 336 of transfer table 202, shift motor 169 and be cut off (S309), paper outputs to transfer table 202, determine to migrate out oral instructions sensor 303 and be cut off (S310), determine whether this paper is last paper (S311), if this paper is not last paper, repeat so from the treatment step of (S303) beginning.If paper is last paper, so at a last paper warp specific time later, perforation on the transport path inlet roller 1 and the conveying roller 5 in the middle of conveying roller 2 and the transfer table transport path and the rotation of shifting outlet roller 6 stop (S312), the screw actuator that is used to drive path selector 14 and path selector 15 is cut off (S313).Therefore, all pages or leaves that import from imaging device can be output and be sorted into with not binding transfer table 202.At this, the page or leaf of process driling unit 100 obtained perforation and handles before output.
Figure 21 A to Figure 21 C shows the control of stapling mode.Incidentally, in Figure 21, the reference position of parts can be described as HP.
In Figure 21, when the paper from imaging device is inserted into, inlet roller 1 and conveying roller 2 on the perforation transport path; Conveying roller 7 on transport path D, conveying roller 9 and conveying roller 10; Bookbinding outlet roller 11; The registration roller 12 that is arranged among the bookbinding process disk F begins rotation (S401) respectively, is used to drive the screw actuator unlatching of path selector 14, path selector 14 inhour rotations (S402).
Then, end face bookbinding clasp machine S1 detects by bookbinding mobile reference position (HP) sensor 312 (referring to Figure 10), after confirming reference position, clasp machine mobile motor 159 (referring to Figure 10) is driven, end face bookbinding clasp machine S1 moves to gutter pos (S403), perhaps output is detected by output band HP sensor 311 (referring to Fig. 8) equally with 52 reference position, after confirming reference position, output motor 159 is driven, thereby is with output 52 to move to standby position (S404).
In conjunction with the aforementioned processing process, the reference position of hitting paper baffle plate 53 detects by hitting paper baffle plate HP sensor (not shown) equally, and baffle plate 53 moves to standby position (S405) then.In addition, branch's guide plate 54 and movable guide piece 55 move to reference position (S406).Then, determine whether inlet sensor 301 opens (S407), determine whether inlet sensor 301 cuts off (S408), determine that whether bookbinding outlet sensor 305 opens (S409), determines to migrate out oral instructions sensor 305 and whether cuts off (S410).If migrating out oral instructions sensor 303 cuts off, paper outputs to alignment bookbinding process disk so, and owing to there is paper, location screw actuator (SOL) 170 (referring to Fig. 5) open a specific time, registration roller 12 is opened a specific time and is contacted to obtain with paper, by towards back end-stopping plate 51 sidepiece bias voltage paper, the rear end (S411) of alignment paper.
Then, hit paper motor 158 (referring to Fig. 7), hit paper baffle plate 53 and move inward a scheduled volume, after the enterprising row alignment operation of direction, turn back to standby position (S412) perpendicular to the throughput direction of the Width of paper and paper by driving.Therefore the length that being delivered to the paper of alignment bookbinding process disk 1 can be alignd with width and the perpendicular direction of direction parallel with sheet transport direction, repeats for the operation of each paper these (S407) to (S413).If paper is the last paper (S413) in piling up, hit the amount that paper baffle plate 53 moves inward a regulation so, becoming with the end face that prevents page or leaf does not line up (S414), and end face bookbinding clasp machine S1 opens under this state, and end face bookbinding unlatching is also carried out (S415).
Simultaneously, the amount of a regulation guarantees output gap (S416) thereby transfer table 202 descends, and shifts the rotation (S417) that output motor begins to shift outlet roller 6 thereby drive.In addition, thus output motor 159 open and make output be with 52 rotations, one scheduled volume, institute's bound pages is stacked on the direction of transfer table transport path C and raises, the roll gap between the outlet roller 6 is shifted in the folded wedging of page or leaf, is delivered to transfer table 202 (S418).Then, determine to migrate out oral instructions sensor 303 and whether open (S419), move to the position and the cut-out that migrate out oral instructions sensor 303 and migrate out oral instructions sensor 303, determine that page or leaf is folded whether through migrating out oral instructions sensor 303 (S420) by page or leaf is folded.
Be in when shifting outlet roller 6 and export the readiness of transfer table 202 to when page or leaf is folded, output is with 52 to move to standby position (S421), hits paper baffle plate 53 and moves to standby position (S422) equally.In addition, the rotation of shifting outlet roller 6 after through a specific time stops (S423), and transfer table 202 is increased to page or leaf and accepts position (S424).This raised position is controlled by the page frame table detecting sensor, and this sensor is used to detect the upper surface that is loaded in page folded topmost page or leaf on the transfer table 202, and this a series of operation repeats up to working page folded last (S425).When being folded last of page or leaf, end face bookbinding clasp machine S1 moves to reference position (S426), output is with 52 to move to reference position (S427) equally, hits paper baffle plate 53 and moves to reference position (S428) equally, is positioned at inlet roller 1 and conveying roller 2 on the perforation transport path; Be positioned at conveying roller 7, conveying roller 9 and conveying roller 10 on the transport path D; Bookbinding outlet roller 11; Stop the rotation respectively (S429) with the registration roller 12 that is arranged among the bookbinding process disk F, be used to drive the screw actuator cut-out (S430) of path selector 14.Therefore, bind processing from the page or leaf that imaging device imports at bookbinding process disk F, and export and be loaded into transfer table 202.Incidentally, equally in this case, the page or leaf of process driling unit 100 obtained perforation and handles before output.
Then, with reference to Figure 22 A to Figure 22 C the saddle stitching stapling mode is described.
In Figure 22 A to Figure 22 C, when paper is inserted by imaging device, be positioned at inlet roller 1 and conveying roller 2 on the perforation transport path; Be positioned at conveying roller 7,9 and conveying roller 10 on the transport path D; Bookbinding outlet roller 11; Begin rotation (S501) respectively with the registration roller 12 that is arranged among the bookbinding process disk F, be used to drive the screw actuator unlatching of path selector 15, and path selector 15 inhour rotations (S502).Then, output detects by output band HP sensor 311 equally with 52 reference position, after the position of determining the output band, drives output motor 157, thereby is with output 52 to move to standby position (S503).
In addition, the reference position of hitting paper baffle plate 53 detects by hitting paper baffle plate HP sensor (not shown) equally, hits paper baffle plate 53 then and moves to standby position (S504).In conjunction with the aforementioned processing process, branch's guide plate 54 and movable guide piece 55 move to reference position (S505).Then, determine whether inlet sensor 301 opens (S506), determine whether inlet sensor 301 cuts off (S507), determine that whether bookbinding outlet sensor 305 opens (S508), determines to migrate out oral instructions sensor 303 and whether cuts off (S509).
If bookbinding outlet sensor 305 is opened and is migrated out oral instructions sensor 303 and cuts off, because there is paper to output to bookbinding process disk F, so location screw actuator (SOL) 170 is opened a specific time, registration roller 12 is opened a specific time and is contacted to obtain with paper, and by sidepiece bias voltage paper towards back end-stopping plate 51, the rear end of paper alignment (S510).
Then, hit paper motor 158, hit paper baffle plate 53 and move inward a scheduled volume, after perpendicular to the alignment operation on the direction of the throughput direction of the Width of paper and paper, hit paper baffle plate 53 and turn back to standby position (S511) by driving.Therefore, the paper that is delivered to bookbinding process disk F aligns at length and width and perpendicular to the direction of the direction that parallels with sheet transport direction, and these operations S506 to S512 repeats for each paper, if this paper is for handling last paper (S512) in piling up, hit paper baffle plate 6 so and move inward an amount of stipulating, do not line up (S513) with the end face that prevents page or leaf.
In this state by opening output motor 157, output is with the amount (S514) of 52 rotations, one regulation, the folded gutter pos that is increased to saddle stitching bookbinding clasp machine S2 of page or leaf is opened saddle stitching bookbinding clasp machine S2, thereby is carried out saddle stitching bookbinding (S515) at the folded center of page or leaf.
Then, the amount of branch's guide plate 54 and movable guide piece 55 skews one regulation, thus form the transport path (S516) that folds process disk G towards the centre.At this, folded conveying roller 71 of upper page and the folded conveying roller 72 of lower page in the folding process disk G in centre begin rotation (S517) respectively, the reference position (HP) of the movable back end-stopping plate 73 on folded transfer guide 91 of the upper page in the middle of being arranged among the folding process disk F and the folded transfer guide 92 of lower page is detected, and moves to standby position (S518).
As mentioned above, when being provided for the system that the acceptance page or leaf is folded in the folding process disk G in centre, output is with 52 amounts (S519) of additionally rotating a regulation, determines that whether arriving page or leaf by the folded front end of the page or leaf of outlet roller 56 and pressure roll 57 wedged conveyings is laminated to and reaches sensor 321 (S520).
When determining that page or leaf is laminated to when reaching sensor 321 and detecting the folded front end of page or leaf, the rotation of folded conveying roller 71 of upper page and the folded conveying roller 72 of lower page stops (S521), and the pressured state of lower page conveying roller 72 is released (S522).
Then, the folding operation of folded sheet 74 begins (S523).In this operation, the rotation of a pair of folding roller 81 and bottom outlet roller 83 begins (S524), opens (S525) through out-of-date folding unit by sensor 323 by the page or leaf of determining to export and fold in institute, and Buck Plate 74 turns back to reference position (S526).
Determine since page or leaf folded whether cut off (S527) through the folded channel sensor 321 of page or leaf, when described page or leaf folded by the time compress the folded conveying roller 72 of lower page, this will be for handling the folded preparation for delivery (S528) of next page or leaf.When through the folded outgoing position of page or leaf, branch's guide plate 54 and movable guide piece 55 move to reference position (S529) in addition.
Thereby when cutting off by sensor 323 by sensor 323 folding units (S530) owing to the folded process of middle folding page or leaf folding unit, double-type folding roller 81 and bottom outlet roller 83 stop (S531) after a specific time, output is with 52 to move to standby position (S532), hits paper baffle plate 53 and moves to standby position (S533) equally.Then, determine whether to be page or leaf last page or leaf (S534) in folded that last page or leaf if not page or leaf in folded is back to step S506 and repeats subsequently step.If last page or leaf, output is with 52 to turn back to reference position (S535).
At this, hit paper baffle plate 53 and move to reference position (S536) equally, inlet roller 1 and conveying roller 2 on the perforation transport path; Conveying roller 7 on transport path D, conveying roller 9 and conveying roller 10; Bookbinding outlet roller 11; Stop (S537) with the rotation that is arranged on the registration roller 12 among the bookbinding process disk F, be used to drive same cut off (S538) of branch's screw actuator (branching solenoid) of path selector 14, each parts turns back to initial state.Therefore, accept the saddle stitching bookbinding from the page or leaf of imaging device importing at bookbinding process disk F and handle, be subjected to middle folding the processing at folding process disk G, middle folding page of output also is loaded into lower disc 203.
In carrying out the page or leaf after-treatment device of above-mentioned output mode, the feature of this embodiment is described with reference to Figure 23 A to 23C, 24,25A and 25B.
The feature of this embodiment corresponding to the output of feedway with 52 and be arranged in the structure of the discharge pawl 52a of this output on 52.It is folded by the described page or leaf of bookbinding on thickness direction to discharge pawl 52a, prevents from that the folded end edge of page or leaf from becoming not line up.
In Figure 23 A, be arranged on output and be constructed with: areal of support (mounting face) 52a1 that is used to support page or leaf with the discharge pawl 52a on 52; Be positioned at output with the stop portion 52a2 on 52 sidepieces, this sidepiece is on the end on the page or leaf thickness direction of areal of support 52a1; Roughly parallel opposed faces (opposite face) 52a3 with page or leaf; With by the bent portion P on the part that is arranged on opposed faces 52a3 (referring to Figure 23 C), towards the outside open pilot unit of forward edge (guide unit) 52a4.
By discharging each parts of pawl 52a, the size of page or leaf on thickness direction has following relation with back end-stopping plate 51.
When the thickness direction of page or leaf in the scope of its actual position that is fixed in areal of support 52a1 by the folded base portion that reaches described opposed faces 52a3 together is of a size of H1, when being of a size of H2 on the thickness direction of the page or leaf in the page or leaf areal of support of back end-stopping plate 51,
H1＜H2。
Simultaneously, as Figure 23 A and shown in Figure 24, when the size of forward edge that page or leaf is increased to pilot unit on thickness direction during as H3,
H1＜H2＜H3。
Aforesaid size H1 is such size, and this size makes the thickness that is contained in the page or leaf among the bookbinding process disk F have 1 to 2mm surplus.
In the structure of the type, when the page or leaf after discharge pawl 52a takes out with 52 cooperatings with output in the end-stopping plate 51 is folded, page or leaf is folded to be gathered towards areal of support 52a1 by pilot unit 52a4, and it is folded neat that having in the end-stopping plate 51 of back do not line up the direction (thickness direction) of page or leaf group towards stop portion 52a2 sidepiece along page or leaf at edge.
The page or leaf group is folded together at stop portion 52a2 sidepiece, when the areal of support 52a1 that is discharged from pawl 52a when the page or leaf end accepts, areal of support 52a1 is narrower than the size of back end-stopping plate 51 on the page or leaf thickness direction, and further, provides the opposed faces 52a3 that is parallel to described page or leaf in the position of distributing like this.Therefore, because that page or leaf is stacked on the thickness direction is pressurized, thereby can keep the bookbinding state of end.In other words, about the page or leaf group, because the end will slide past pilot unit 52a4 and be contained between the opposed faces 52a3, shown in Figure 23 B, different with the discharge pawl that only has pilot unit 52a0 (representing with Reference numeral 52P for convenience's sake), the end that slides past pilot unit 52a0 can not become in the position that stops to slide and not line up.
Structure among Figure 23 C shows such situation, and opposed faces 52a3 is the surface that is parallel to page or leaf, but in order easily the end of page or leaf to be imported, areal of support 52a1 is crustal inclination a little.Incidentally, the Reference numeral 52b among Figure 23 C is the guide on page top of aliging by reduction discharge pawl 52a.
According to this structure, even the edge does not line up with in disorder in rear end surface 51, take out the page or leaf group when discharging pawl 52a, the end of page or leaf will in one direction (thickness direction) together folded, and be transferred owing to remaining under so folded neat state at pressurized on this direction.Therefore, can prevent the in disorder of end edge, and prevent the end edge that in the folding bookbinding in centre treating process, does not line up and become remarkable.Especially, when page or leaf owing to being removed when being loaded on the areal of support, effect nextpage end at pilot unit 52a4 is gathered towards areal of support, because this page end will be bound on thickness direction, can be only by output with 52 mobile the alignment of end edge is automatically carried out, do not need to provide other aligning apparatus.
Another feature of this embodiment then, is described with reference to Figure 25 A and Figure 25 B.
Another feature is the structure of accurately also binding processing on the thickness direction of page or leaf effectively.In Figure 25 A and Figure 25 B, discharge pawl 52a has the flexible piece 100 that can face and contact page or leaf.Flexible piece 100 is for having for example polyester sheet and can obtain the member of elastic resilience of low friction coefficient, and the bottom is installed on the pilot unit 52a4, near forward edge extension areal of support 52a1, thus page or leaf can remain under the state that enters guide position.
By flexible piece 100, from and the integrally formed part of pilot unit 52a4 can set according to following situation to the length the forward edge of stretching out on the areal of support 52a1 sidepiece, thereby the elastic deformation amount can change according to the number of page or leaf.
Usually, when the page or leaf that uses than peanut, shown in the Reference numeral L among Figure 25 A, the size of flexible piece 100 should be by realizing preventing that with contacting of opposed page or leaf the margin edge is shifted to opposed faces 52a3 sidepiece.In other words, when the number of page or leaf causes it to have the littler thickness of size H1 than areal of support 52a1, flexible piece 100 contacts with page or leaf and page or leaf is pressurizeed, thereby prevent the in disorder of page end edge, gap between the forward edge of flexible piece 100 and the areal of support 52a1 is length S0, so this forward edge is stretched out from opposed faces 52a3 at areal of support 52a1 sidepiece.
In addition, the length of above-mentioned flexible piece 100 satisfies following condition equally.
Page or leaf in being contained in areal of support 52a1 is a such thickness, the gauge H1 of this thickness and areal of support 52a1 (thickness shown in the Reference numeral L+ β among Figure 25 B) is close, elastic deformation will take place in flexible piece 100, pendulum radius scope in this deformation process is a size (using the gap shown in the Reference numeral S0-α in Figure 25 B), this size can not hinder the importing of page or leaf, and its forward edge can not disturbed areal of support 52a1.Therefore, the page or leaf of insertion will slide past the surface of flexible piece 100, and this surface is parallel with pilot unit 52a4, and the end edge of the page or leaf of described insertion will be contained among the areal of support 52a1.No matter because the thickness of page or leaf, no matter be in the elastic deformation process or under initial state, pressure can be applied on the page or leaf, and the page or leaf that is contained among the areal of support 52a1 can be folded on thickness direction together at stop portion 52a2 sidepiece, can prevent the in disorder of page end edge thus.
According to first embodiment, can obtain following effect.
(1) the in disorder of end edge can prevent by forcibly folding the page or leaf that takes out with feedway together.Especially, by bound pages under such state, be under the state of thickness than the thin thickness of the page or leaf in the page or leaf accomodating unit of the page or leaf in the feedway, can prevent the in disorder of end edge and can eliminate not lining up of end edge, and prevent the generation that do not line up at process medial end portions edge by saddle stitching or middle folding bookbinding.
(2) by on thickness direction, forcibly folding neat page or leaf with a kind of simple structure, can avoid the end edge that do not line up, described simple structure reliably is the structure of the size of page or leaf area supported on thickness direction of regulation page or leaf accomodating unit and feedway only.
(3) wall surface (wall surface) in the face of page or leaf is configured to and the page or leaf almost parallel in the feedway, and such parallel walls surface can be used as the holding unit (holding unit) of page or leaf.Therefore, the page or leaf that can prevent to be loaded on the feedway area supported collapses absent-mindedly, can prevent equally because the end edge that does not line up of collapsing and being caused.
(4) owing to feedway has from the outside open pilot unit of opposed faces of the wall surface of facing page or leaf, described pilot unit outwards opens by the sweep that is extended to opposed faces, thereby the importing of the page or leaf that is taken out can carry out exactly, and the page or leaf by will be imported be collected at can easily fold on the opposed faces neat import page.Therefore can prevent the end edge that does not line up.
(5) utilize the simple structure of only distributing the area supported of page or leaf in the feedway; The area supported of the page or leaf in the page or leaf accomodating unit; With the forward edge of pilot unit, the importing of the page or leaf in the transport process process of feedway and the processing that is used to eliminate the end edge that does not line up can be carried out simultaneously.
(6) because feedway has the flexible piece that can face and contact page or leaf, the page or leaf of importing feedway can be easily together folded by the elasticity quilt of flexible piece.
(7) since flexible piece towards the importing position of page or leaf forward, especially because the pilot unit of basic end and feedway is an one, thereby flexible piece can play the effect of the extendible portion of pilot unit.Therefore, this helps the importing of page or leaf, and can easily fold neat page or leaf, with eliminate import page not the lining up of end edge.
(8) because flexible piece produces elastic deformation according to the thickness of page or leaf, especially because the hunting range of this elastic deformation can not hinder the importing of page or leaf, thereby the page or leaf that imports can easily obtain folded together by elastic force, therefore can prevent the end edge that does not line up.
(9), and need not increase the folded neat structure of special end edge because page or leaf takes out by the feedway on the part of installing and being connected band, thereby the end edge that does not line up of page or leaf can utilize existing correct-by-construction.
(10), can prevent after image forms because the relatively poor outward appearance of the end edge that bookbinding causes by in the process of bookbinding treating process, avoiding end edge not line up.
Second embodiment
The main purpose of second embodiment is to realize above-mentioned second purpose of the present invention.
Incidentally, above-mentioned Fig. 3 to Figure 22 that first embodiment is described of being used for, and, roughly can be applied to description, and its unnecessary description is omitted to second embodiment with reference to the description of Fig. 3 to Figure 22.Following description is primarily aimed at the feature of second embodiment.
At first, the fold line angle adjusting mechanism that is used for second embodiment is described.
In a second embodiment,, there is such situation, promptly do not line up at above-mentioned actual mechanical process fold line though page or leaf is folding in the centre by folded sheet 74.This situation be because to be cut into standard-sized page or leaf can not be rectangle accurately.Therefore, in this embodiment, a fold line angle adjusting mechanism (after this abbreviating regulating mechanism as) that is used to regulate the angle of the folded superimposing thread of page or leaf is set, is used to handle such problem.Figure 26 A and Figure 26 B show first example of this regulating mechanism.Figure 26 A is the front elevation of observing from the front side of page or leaf after-treatment device, and Figure 26 B is the lateral plan of Figure 26 A.
Shown in Figure 26 A and Figure 26 B, movable back end-stopping plate 73 is set, this baffle plate 73 has the folded bearing surface (supportface) of page or leaf that is used to support and aligns and carry along the folded guide 92,91 of upper and lower page or leaf, this baffle plate can raise and reduction by back end-stopping plate mobile motor (back end fence movement motor) 163, and folded at two some upper support pages or leaves.Movable back end-stopping plate 73 and back end-stopping plate mobile motor 163 are installed on the pedestal 501, and pedestal 501 is rotatably supported around the folded transfer guide 91 of the lower page of rotary support member 501a.Be provided with set screw (adjustmentscrew) 503 and compression spring 504 (right side of figure) in the lower end of pedestal.Set screw 503 is passed compression spring 504 from the outside of front side plate, and is connected on the pedestal 501 by bolt portion 503a.Compression spring 504 has the elastic force that is used for towards back plate sideway swivel pedestal 501, and by rotating set screw 503 to the right, can be by bolt portion 503a extension spring and rotate towards front plate side in pedestal 501.Simultaneously, by rotating set screw to the left, screw fluffs, and pedestal 501 can be by compression spring 504 towards back plate sideway swivel.
Therefore, pedestal 501 is configured to can regulate by page folded fold line of movable back end-stopping plate 73 supports and the aft end face on the folded throughput direction of page or leaf by set screw 503, promptly, by 2 aft end faces that are supported on the page or leaf folded (page or leaf) on the end-stopping plate 73 of movable back, make that the angle [alpha] that forms thus is 0 degree (parallel), after this can utilize lock screw 505 that they are fixed on the header board and back plate on the pedestal fixed cell 501b.If desired, can utilize the convenient adjusting of cam mechanism or kindred organization.Incidentally, be formed on the end face and the angle between the fold line that are parallel to page throughput direction and can also be adjusted to 90 degree.
Second embodiment of regulating mechanism is illustrated among Figure 27 A and Figure 27 B.Figure 27 A is the front elevation of observing from the front side of page or leaf after-treatment device, and Figure 27 B is the lateral plan of Figure 27 A.
In this second embodiment, sidepiece baffle plate 510,511 is set, be used on the direction of the folded page or leaf throughput direction of the page or leaf that is parallel to first embodiment, regulating operation.In a second embodiment, be installed in having on the pedestal 501: movable back end-stopping plate 73, have bearing surface, this bearing surface is folded at the direction upper support page or leaf perpendicular to throughput direction; Be used to drive the back end-stopping plate mobile motor 163 of this movable back end-stopping plate 73; Before side shield 510 and back side shield 511, these baffle plates have and are used for keeping the folded maintenance face (retention face) of page or leaf being parallel to the direction of throughput direction (Width); With the sidepiece baffle plate mobile motor 515 that is used to drive described sidepiece baffle plate 510,511, pedestal 501 is rotatably supported by the lower page transfer guide 91 around rotary support member 501a.In a second embodiment, it is folded that point of movable back end-stopping plate 73 usefulness supports page or leaf, and the both sides of supporting blade keep by preceding and rear lateral portion baffle plate 510,511.Identical in the structure of other parts and first example.
In this second example, after adjusting set screw 503, be adjusted to 90 degree in the end face and the angle [alpha] between the fold line that are parallel to the folded page or leaf throughput direction of page or leaf, this angle is passed through in the lock screw 505 at the pedestal fixed cell 501b place of front and rear panel fixing.Under the situation of this embodiment, because movable back end-stopping plate 73 is some supports, angle is observed by sidepiece baffle plate 510,511.
In addition, in the process of folding operation, folded sheet 74 be supported on page or leaf on sidepiece baffle plate 510,511 and the back end-stopping plate 73 splice touch a specific time after, before contact folding roller 81, stop the folded support operation of 510,511 pairs of pages or leaves of sidepiece baffle plate, page or leaf is folded and is recalled certain distance.
Incidentally, though pedestal 501 can rotate in aforesaid first and second embodiment, because the final purpose of this embodiment is the angle [alpha] that is formed by page or leaf superimposition fold line in order to regulate, thereby movable back end-stopping plate 73 and sidepiece baffle plate 500,501 position can be regulated independently, is the angle [alpha] of 0 degree or 90 degree to obtain.In addition, though this angular adjustment is usually by folding page or leaf and observe output page or a folded state that page or leaf is folded carries out, a scale is set having on the header board 64a of set screw 503, therefore can know the regulated quantity of set screw 503, and the user can see the variation of the folded angle [alpha] of page or leaf or page or leaf with respect to fold line according to the rotation amount of rotation set screw 503.
Figure 28 shows the keystone configuration of another embodiment of screw mechanism (screw mechanism), and this structure is used for regulating the position of rotation of the pedestal 501 of first and second examples.In this embodiment, adjusting gear 550 is set and is used to replace the set screw 503 shown in Figure 26 A and Figure 26 B and Figure 27 A and Figure 27 B with adjusting motor 555.This adjusting motor 555 is used to drive adjusting gear 550, with the adjusting gear 550 bolt portion 550a rotation of (with one heart) setting coaxially, thereby as above-mentioned set screw 503 adjusting angles.In other words, because the rotation amount of screw and the rotation amount of pedestal 501 are roughly identical ratio, if pulse motor is as regulating motor 555, the rotation amount of each pulse can determine that the adjusting of the angle [alpha] between the page or leaf superimposition fold line can only easily be carried out by the control to motor.In addition since automatically controlled be feasible, if regulated quantity can be from the input of a control panel or similar panel the time, be regulated operation and can be carried out at an easy rate by operating a control panel.
Incidentally, because the length from the reference position of movable back end-stopping plate 73 to fold line changes, if carry out angular adjustment, when the input regulated quantity when carrying out such adjusting, 360 pairs of reference position to distances between the fold line from movable back end-stopping plate 73 of CPU are operated with adjusting angle, the position (vertical direction) of end-stopping plate 73 after regulating movably simultaneously, and move movable back end-stopping plate 73, so fold and can carry out exactly in the centre at page or leaf center.Thus, fold line do not line up and not lining up of middle folding position can accurately obtain proofreading and correct.
