When discharge bookbinding sheet processed is piled up, open and close guide plate 33 quilts to the top pull-up, and recover at predetermined instant, the detection signal that this moment basis moves grate paper-arranaging sensor 303 is confirmed.Its stop position is confirmed according to the detection signal that row's paper guide plate opens and closes sensor 331, and is opened and closed motor 167 drivings by row's paper guide plate.In addition, row's paper guide plate switching motor 167 comes drive controlling through the On/Off that row's paper guide plate opens and closes limit switch 332.
The structure of the bookbinding processing pallet F that implements the bookbinding processing is described.
Fig. 5 is from seeing that perpendicular to the direction of paper transmission plane bookbinding handles the planar view of pallet F, and Fig. 6 illustrates the block diagram that pallet F and its driver train are handled in bookbinding, and Fig. 7 is the block diagram that the output mechanism that paper piles up is shown.At first, as shown in Figure 6, will be loaded in bookbinding successively to the paper of binding processing pallet F by 11 guiding of bookbinding exit roller and handle on the pallet F.In the case, carry out the vertically integration of (paper conveyance direction), carry out the laterally integration of (direction vertical with paper conveyance direction also claimed paper width direction) through sign indicating number paper hurdle 53 with knocking 12 pairs of every paper of roller (knock roller).Last paper to next paper of promptly piling up at the intermittence of operation from paper pile up at first between one, drive end face clasp machine S1 according to bookbinding signal, thereby bind processing from control part.Carry out paper that bookbinding handles and piled up and be equipped with the discharge of discharging pawl 52a immediately and be with 52 to be sent to and to move exit roller 6, and be expelled to the mobile pallet 202 that is arranged on receiving position.
As shown in Figure 7, discharge pawl 52a and detect original position, and discharge band HP sensor 311 through discharging pawl 52a On/Off through discharging band HP sensor 311.With discharge on 52 periphery two relative of position configuration discharge pawl 52a, be accommodated in the paper that bookbinding handles among the pallet F and pile up thereby alternately move to transmit.In addition, as required, can also backward rotation discharge and be with 52, move that paper is piled up and the discharge pawl 52a of standby aligns with the back side of the discharge pawl 52a of opposite side is accommodated in the direction of transfer front end that the paper among the bookbinding processing pallet F is piled up to be utilized as.Neat unit on the paper conveyance direction that this discharge pawl 52a also piles up as paper and playing a role.
As shown in Figure 5, be discharged from discharge that motor 157 drives with 52 axle drive shaft on, with respect to be with in the discharge of the Integration Center of paper width direction 52 with its drive pulley 62 configuring fixed distributing roller 56 symmetrically.And the circumferential velocity of these distributing rollers 56 is set to faster with 52 circumferential velocity than discharge.
As shown in Figure 6, knock screw actuator 170 and make that to knock roller 12 be center swing with fulcrum 12a, send into bookbinding and handle the paper among the pallet F thereby act on off and on, thereby make paper collision hurdle, rear end 51.In addition, knocking 12 inverse times of roller nail rotates.Sign indicating number paper hurdle 53 is driven through synchronous be with (timing belt) by the sign indicating number paper motor 158 of the positive and negative rotation of ability, thereby comes and goes mobile at paper width direction.
Among Fig. 8, end face clasp machine S1 is driven through band synchronously by clasp machine mobile motor 159 that can positive and negative rotation, on paper width direction, moving in the desired location of sheets end.The clasp machine that one end of its moving range has the original position that detects end face clasp machine S1 moves HP sensor 312, and the gutter pos of paper width direction is controlled from the amount of movement of original position through end face clasp machine S1.Shown in the block diagram of Fig. 9; End face clasp machine S1 constitutes ordering into angle of will following closely and changes to and paper end parts parallel or inclination; And, can constitute the binder mechanism portion that only makes clasp machine S1 in position and rotate into predetermined oblique angle, thus the exchange of following closely easily.Clasp machine S1 tilts to rotate because of inclination motor 160, if nail switch sensor 313 detects the switch that has arrived pre-determined tilt angle or nail, then inclination motor 160 stops.In case inclination is bound end or followed closely to exchange to tie and pile up, clasp machine just turns to original position, and preparation is bound next time.
Like Fig. 1 and shown in Figure 5; It is to be equivalent to more than the half the distance of direction of transfer length of maximum sheet size that can saddle stitching that saddle gang stitcher S2 is configured to make the distance of the nailing position from hurdle, rear end 51 to saddle gang stitcher S2, and the Integration Center of paper width direction disposes two saddle gang stitcher S2 symmetrically and is fixed on the pillar 63 relatively.When carrying out saddle stitching; Integrate the direction vertical with sign indicating number paper hurdle 53, and integrate the direction of transfer of paper with knocking roller 12, then with hurdle, rear end 51 with the direction of transfer of paper; Drive and discharge with 52 and with lifting the rearward end that paper is piled up on the discharge pawl 52a; The central part that makes the direction of transfer that paper piles up is in the gutter pos of saddle gang stitcher S2, and stops in this position, carries out the bookbinding action.Paper after the bookbinding is piled up and is transferred into doubling processing pallet G side, and carries out doubling.
Figure 10 and Figure 11 are the action specification figure of the travel mechanism of the explanation folded sheet 74 that is used to carry out doubling.
Come supported folding plate 74 through making two axle 64c trips that erected by front and back side plate 64a, 64b respectively be embedded in the 74a of slotted hole portion.And the upright axial region 74b trip of being located at folded sheet 74 is embedded in the 76b of slotted hole portion of connecting arm 76, and making connecting arm 76 is that the center is shaken with fulcrum 76a, moves thereby folded sheet 74 is come and gone about ground as shown in Figure 10 and Figure 11.Promptly; The axial region 75b trip of folded sheet power cam 75 is embedded among the 76c of slotted hole portion of connecting arm 76; Connecting arm 76 shakes through the rotational motion of folded sheet power cam 75; Corresponding therewith, in Figure 12, folded sheet 74 following relatively pile transmit guide plate 91, on pile transmit back and forth movement on the vertical direction of guide plate 92.
Folded sheet power cam 75 rotate along the direction of arrow among Figure 10 through folded sheet drive motor 166.Its stop position is confirmed at blocking-up portion 75a both ends through detecting the first quarter moon shape with folded sheet HP sensor 325.
Figure 10 illustrates to pile up from the paper of handling pallet G and takes in the original position that keep out of the way fully in the zone.In case folded sheet power cam 75 are rotated along the direction of arrow, folded sheet 74 moves to the direction of arrow, piles up and takes in the zone thereby project to the paper of handling pallet G.Figure 11 illustrates the paper of handling pallet G is piled up the position that central authorities are pressed into the roll gap of folding roller 81.In case folded sheet power cam 75 are rotated along the direction of arrow, folded sheet 74 moves to the direction of arrow, takes in the zone and keeps out of the way thereby pile up from the paper of handling pallet G.
In the first embodiment, be prerequisite though doubling is piled up with folded sheet, also go under the situation of folding 1 paper.At this moment, owing to only have 1 then to need not saddle stitching,, carry out folding the processing through folded sheet 74 and folding roller, and be expelled to down pallet 203 so, send into doubling and handle pallet G side in the moment of discharging a piece of paper.
Then, the folding roller unit of strengthening is described.As shown in Figure 1, have the folding roller unit 400 of strengthening on the transfer path H between folding roller 81 and the exit roller 83.After will piling up the roll gap of filling in folding roller 83 and stamp folding line with folded sheet 74 folding paper, strengthen folding line with the folding roller unit 400 of strengthening.
Shown in the lateral plan of the front elevation of Figure 13, Figure 14, the folding roller unit 400 of strengthening has folding roller 409, folding supporting mechanism and the folding driver train of strengthening roller of strengthening roller strengthened.The folding driver train of strengthening roller is made up of with 403 pulse motor 401 (Figure 14) in two pulleys 402, ring shaped synchronous belt 403 and rotating drive between 404 drive side pulley 402, slave end pulley 404, frame synchronously.
The folding supporting mechanism of strengthening roller 409 is by following component set-up: with combines with 403 synchronously and mobile integratedly mobile support portion 407; Move the guide portion of sliding and limit moving direction in support portion 407 405; Extend to the folded roller side of strengthening of the reflexed that moves support portion 407 and also limit the folding upper guide plate 415 that roller 409 tilts to prevent simultaneously 405 bendings of guide portion of strengthening; The folding roller support portion 408 of strengthening; Pile up folding direction (at Figure 13 to paper; Below among Figure 14) strengthens the elastomeric material as the elastic force applying unit (being coil spring among Figure 13) 411 that roller 409 applies elastic force to folding.Supporting mechanism is configured on the direction vertical with paper conveyance direction, and driver train moves folding roller 409 direction that is provided with to supporting mechanism in supporting mechanism of strengthening.
The rotating drive of pulse motor 401 through frame between drive side pulley 402 and the slave end pulley 404 synchronously with 403 be passed to synchronously with the 403 mobile support portions 407 that combine; Move support portion 407 by 405 guiding of guide portion, and slide mobile to the thrust direction of guide portion 405.Move between support portion 407 and the upper guide plate 415 and have anti-bending 406, anti-bending 406 is moved support portion 407 supports and forms the roller shape with the state that can rotate, so can be mobile on the direction of principal axis of guide portion 405 integratedly with mobile support portion 407.The folding roller 409 of strengthening is configured between mobile support portion 407 and the bottom guide 416, on the periphery of folding reinforcement roller 409, has friction part 410.The folding roller 409 of strengthening comes and goes mobile.
The folding turning cylinder of strengthening roller 409 is folded to be strengthened roller support portion 408 and supports, and slides with mobile support portion 407 in the folding roller support portion 408 of strengthening, and is supported for the state that can move at above-below direction simultaneously.And elastomeric material 411 pressurizes to 416 pairs of folding roller support portions 408 of strengthening of bottom guide from moving support portion 407.Thus, folding strengthen roller 409 can with mobile support portion 407 integratedly the thrust direction of guide portion 405 move, therebetween, folding strengthen roller 409 constantly by elasticity material 411 to bottom guide 416 pressurizations, and move at above-below direction.In addition, on the thrust direction of guide portion 405, have front position detecting sensor 412 and the back position-detection sensor 413 that detects the position of moving support portion 407 as detecting unit.Move support portion 407 be positioned at position-detection sensor before 412 and position-detection sensor after under the situation of 413 position, front and back position detecting sensor 412,413 detects and moves support portion 407.The detecting sensor 414 of piling up paper detects the paper that is transferred into folding reinforcement roller unit 400 and piles up.
Back position-detection sensor 413 detects the folding original position of strengthening roller 409.Paper pile up be transferred into the desired location and folding strengthen action and stop after, strengthen roller 409 position-detection sensor 413 move to the position of front position detecting sensor 412 from the back folding.At this moment; Pulse count; Behind the predetermined pulse number, under front position detecting sensor 412 detects less than the folding situation of strengthening roller 409, be judged as folding the reinforcement in the moving of roller 409 and have unusually (stopping of causing of the pinning of mechanism, driving torque deficiency, electrical fault).
Exist when unusual being judged as, carry out backward rotation pulse motor 401 and the action returned of position-detection sensor 413 directions backward.At this moment, show that on display part paper stops up.
Figure 15 is the block diagram that the control of paper processing device is shown.Control part 1500 has CPU1501, I/O interface 1502.From the signal of each switch of the control panel of image processing system PR etc. and sensor 1503 through I/O interface 1502 to CPU 1501 inputs.CPU 1501 comes the driving of control solenoid (solenoid) 1504, motor 1505 according to incoming signal.
For example, from inlet sensor 301, move that grate paper-arranaging sensor 303, paper detecting sensor 330, row's paper guide plate open and close that sensor 331, paper have or not sensor 310, discharge band HP sensor 311, clasp machine moves HP sensor 312, signal that nail switch sensor 313, folded sheet HP sensor 325, front position detecting sensor 412, back position-detection sensor 413, paper are piled up detecting sensor 414 is input among the CPU 1501.
The control of sheet post-process apparatus PD, abnormality detection are controlled and the demonstration control of display part 1507 are carried out the program that writes storage part 1506 through CPU 1501 carry out.In addition, the demonstration of the operation display part among image processing system PR control is controlled according to the control output from CPU1501 by the CPU that image processing system PR is had.
Below, explain from a series of flow process when unusual takes place.Even drive pulse motor 402 and make folding strengthen roller 409 backward position-detection sensor 413 directions move, if not conducting of back position-detection sensor 413 in the given time, then paper stops up, and produces unusual.At this moment, demonstration has produced the paper obstruction on the operating portion of image processing system PR.And sheet post-process apparatus PD has display part, also may be displayed on the display part 1507.Obstruction is meant that in the folding reinforcement action that utilizes folding reinforcement roller 409, this folding roller 409 of strengthening abends, thus the state that paper can't be transmitted.
Figure 16 is the figure that the folding reinforcement roller 409 that returns the distance of having implemented folding reinforcement is shown.Counting with front position detecting sensor 412 and back position-detection sensor 413 step number that is driven by pulse motor 401 after closing is judged the folding miles of relative movement of roller 409 in the mobile driving vertical with paper conveyance direction of strengthening.When stopping up; If folding reinforcement roller 409 is the states that stop at position shown in Figure 16; The counting of the step number of back position-detection sensor 413 after closing is below the half the step number of the folding driving distance of strengthening roller 409, and to be judged as be the position near as the original position of retreating position.
Judging that the folding roller 409 of strengthening is that shown in figure 16, the folding roller 409 of strengthening moves to arrow a direction under the situation near the position of original position.Shown in figure 14, folding reinforcement roller 409 moves to the outside of the paper width in the processing, thus reposition.But, even be not to be positioned at original position, so long as folding strengthen that roller 409 moves to the outside of the paper width in the processing and the position of keeping out of the way gets final product.
When stopping up; If folding reinforcement roller 409 is the states that stop at position shown in Figure 17; Then folding reinforcement roller 409 is turned back; After front position detecting sensor 412 was closed, the counting of step number was to fold below the half the step number of the driving distance of strengthening roller 409, and was judged as the position of the relative position (position of turning back) near original position.In addition, though back position-detection sensor 413 close after the counting of step number be half of the folding driving distance of strengthening roller 409 more than the step number, also being judged as is the position near the relative position of original position.CPU 1501 carries out position judgment and the control based on the folding reinforcement roller 409 of step number.
Judging that the folding roller 409 of strengthening is under the situation near the position of the relative position of original position, shown in figure 17, the folding roller 409 of strengthening moves to arrow b direction.Shown in figure 18, folding reinforcement roller 409 moves to the outside of the paper width in the processing, moves to the relative position of original position.But, even be not positioned at the relative position of original position, as long as the folding roller 409 of strengthening moves to the outside of the paper width in the processing and the position of keeping out of the way.After folding reinforcement roller 409 was kept out of the way, the user removed paper.After stopping up releasing, the 409 automatic repositions of folding reinforcement roller.
The unit of counting miles of relative movement also can not be the counting based on the step number of the driving of pulse motor 401 as distance detecting portion, but through coder the folding miles of relative movement of strengthening roller 409 counted.For example, can on drive side pulley 402 or slave end pulley 404, have wheel changes coder, thereby detects miles of relative movement, also can possess linear encoder at upper guide plate 415, thereby detects miles of relative movement.
Through detecting miles of relative movement, can detect the folding reinforcement roller 409 that stops when stopping up to respect to the distance of the 1st position of paper width and distance to the 2nd position.If to respect to the distance of the 1st position of paper width than near to the distance of the 2nd position, then foldingly strengthen roller 409 and move to the 1st position.On the other hand, if to respect to the distance of the 2nd position of paper width than near to the distance of the 1st position, then foldingly strengthen roller 409 and move to the 2nd position.For example, establishing the 1st position is original position, and the 2nd position is the relative position of original position.But, also can establish the relative position that the 1st position is an original position, the 2nd position is an original position.
Can shorten the folding roller 409 of strengthening to processing time that retreating position moves through above structure.
