Fig. 9 is the scheme drawing according to the main body of the pile deflection unit of the paper processing device of first embodiment.Pile is sent to folding when handling pallet G when handle pallet F from end-face-bookbinding, as shown in Figure 9, pushes away the rear end of handling the pile that the jogger grid 53 among the pallet F align by rear end grid 51 and end-face-bookbinding on the ratchet 52a by discharging.Be positioned at roller 601 that end-face-bookbinding handles pallet F top and clamp piles, and pile is applied conveying capacity with the driven voller 607 relative with roller 601.In this case, the roller 601 in the pile front is in readiness in the position that roller 601 is not run into the pile front end.As be used to illustrate the shown in Figure 10 of relative position between distributing roller 56 and the connecting gear 600, distance L 1 is arranged to be sent to the folding maximum ga(u)ge L2 that handles the pile of pallet G greater than handle pallet F from end-face-bookbinding, bumps to prevent pile front end and roller 601.Distance L 1 be endways-face-bookbinding handles among the pallet F and piles up the surface of pile and the distance between the roller 601 thereon between alignment period, or guide the surface of pile and the distance between the roller 601 to it when pushing away pile on the discharge ratchet 52a.
Because pile thickness according to endways-quantity and the paper type of the paper that aligns among the face-bookbinding processing pallet F change, so in order to prevent that pile front end and the roller 601 required extreme lower position that bumps from also changing.
Therefore, if according to changing about the information of number of paper and paper type, so also can being used for moving to from retracted position the time of the position that applies conveying capacity, retracted position is set to the necessary minimum time.Help like this increaseing productivity.Can come the mission bit stream of autonomous agent or can obtain about the information of number of paper and paper type from the sensor the paper processing device PD.Yet,, it is contemplated that top of form and roller 601 contact with each other when pushing away pile on the discharge ratchet 52a when generation in the pile of being handled pallet F alignment by end-face-bookbinding is bigger when curling than desired.Therefore, shown in the enlarged drawing of 600 main bodys of connecting gear among Figure 11, adjacent providing in roller 601 fronts transmitted load-carrying element 617, to reduce the angle of the contact between top of form and the roller 601.No matter transmitting load-carrying element is retaining element or elastic element, and the effect that transmits load-carrying element there is no difference.
As shown in figure 12, shown the main body of the pile deflection unit during paper deflection, the roller 601 of connecting gear 600 contacts with paper surface, thereby applies conveying capacity to pile after top of form is by connecting gear 600.In this case, turn to guide member 609 and distributing roller 56 to form the guide piece that is used for knuckle section, and pile is sent to the folding processing pallet G in downstream along this guide piece.
Figure 13 is the scheme drawing of the main body of pile deflection unit during pile is sent to displacement pallet 202 sides.When pile when end-face-bookbinding is handled pallet F and is sent to displacement pallet 202, as shown in figure 13, turn to guide member 609 rotation in the direction of the clock in Figure 13, turn to the outer surface of guide member 609 and guide plate 611 to form the drive access that is connected to displacement pallet 202.Discharge and push away the rear end that the pile of pallet F alignment is handled in end-face-bookbinding on the ratchet 52a, then pile is sent to displacement pallet 202.
When distributing roller 56 is to can't help the driven voller that electric motor driven drive roll drives, and when following the transmission of pile, can the deflection pile and pile is sent to folding pallet G side and pile displacement pallet 202 sides handled.
Figure 14 and 15 diagram of circuit show the control process that is sent to the folding operation of handling pallet G respectively and are sent to Figure 12 and the control process of the operation of displacement pallet 202 shown in Figure 13.Figure 14 is the process flowchart of initial treatment.In initial treatment, CPU 360 carries out cam 605 and turns to guide member 609 to be arranged on the processing (step S101 is to S104) of initial position.
Figure 15 handles the diagram of circuit of pallet F to the control process of the transfer operation of folding pallet G of processing or displacement pallet 202 from end-face-bookbinding.As shown in figure 15, when the beginning task, at first, whether CPU 360 inspection tasks are that (step S201) handled in the center bookbinding.When task was center bookbinding processing, CPU360 rotated predetermined amount with electrical motor M1 and cam 605 from initial position, simultaneously roller 601 is moved to ready position (step S202).Subsequently, CPU 360 is electrical motor M2 and turn to guide member 609 to move predetermined amount from initial position, thus be formed for the deflection pile turn to drive access (step S203).When end-face-bookbinding is handled processing among the pallet F and finished (step S204), CPU 360 utilizes and discharges the discharge (on push away) (step S205) that ratchet 52a begin pile.
When the front end that begins discharging operation and pile passes through the crack position of roller 601 (step S206), CPU 360 rotates predetermined amount with electrical motor M1 and cam 605, and roller 601 is moved to delivering position (step S207).After this, when transmitting operation that pile reaches predetermined transmission distance when finishing (step S208), CPU 360 checks whether these transfer operations are operations of last task.When this transfer operation was not the operation of last task, CPU 360 returned step S202 and repeats identical processing.When task termination (step S209), CPU 360 moves to initial position (step S210) with electrical motor M1 and cam 605, and with electrical motor M2 and turn to guide member 609 to move to initial position (step S211) with end process.
On the other hand, when task in step S201 was not center bookbinding processing, CPU 360 checked whether these tasks are that (step S212) handled in the end face bookbinding.When not carrying out the end face bookbinding yet, CPU 360 direct end process (paper directly is discharged to displacement pallet 202).When carrying out the end face bookbinding, CPU 360 will be sent to displacement pallet 202 through the pile of end face bookbinding.CPU 360 rotates predetermined amount with electrical motor M1 and cam 605 from initial position, thereby roller 601 is moved to ready position (step S213).Subsequently, CPU 360 is with electrical motor M2 and turn to guide member 609 from the predetermined amount of initial position rotation, thereby is formed into the drive access (step S214) of displacement pallet 202.When end-face-bookbinding is handled processing among the pallet F and finished (step S215), CPU 360 utilizes and discharges the discharge (on push away) (step S216) that ratchet 52a begin pile.
When beginning discharging operation and having transmitted preset distance (step S217), CPU 360 checks whether transfer operations are operations of last task.When transfer operation was not the operation of last task, CPU 360 got back to step S213 and repeats identical processing.When task termination (step S218), CPU 360 moves to initial position (step S210) with electrical motor M1 and cam 605, and with electrical motor M2 and turn to guide member 609 to move to initial position (step S211) with end process.
As mentioned above,, provide the connecting gear of paper processing device, and connecting gear comprises the transfer roller and the driven voller relative with transfer roller that transmits paper according to first embodiment.Therefore, the paper process mechanism paper that can align more accurately.
Second embodiment of the invention is different from the first embodiment part and is relatively to provide drive roll with transfer roller.
Figure 16 and 17 is the scheme drawings according to the main body of the paper processing device of second embodiment.Because the element of paper processing device is all identical with element among first embodiment except Figure 16 and the element shown in 17, therefore adopts identical Reference numeral and symbol to represent components identical, and omit repeat specification similar elements.
Although in first embodiment, propulsive effort is applied to the pile outside, and pile is transmitted by connecting gear 600 or pile is turned to by distributing roller 56, and in a second embodiment, propulsive effort also is applied to the inboard and transmission pile of pile.Therefore, change drive roll 614 into and utilize elastic element 608 to make drive roll 614 produce press contacts according to the driven voller (Fig. 4) of first embodiment, thereby also apply propulsive effort (conveying capacity) from the pile inboard with set pressure and roller 601.
Therefore, in the example of Figure 16, the axle drive shaft 602 of driven roller 601 is by the first speed belt T1, first and second gear G1 and the G2, and the second speed belt T2 drives drive roll 614.In this case, the first speed belt T1 drives the first gear G1, with the second speed belt T2 of the first gear G1 ingear, second gear G2 driving to drive roll 614 transmission of drive force.The propulsive effort of axle drive shaft 602 is driven roller 601 and drive roll 614 respectively, when the crack of pile between roller 601 and drive roll 614, transmits pile.
In the example of Figure 17, obtain the propulsive effort of drive roll 614 from the electrical motor M3 that provides that separates with paper processing device.Electrical motor M3 drives the 3rd speed belt T3, applies propulsive effort to drive roll 614, and transmits pile by roller 601 and drive roll 614.
Except that These characteristics, unless spell out, otherwise according to the 26S Proteasome Structure and Function of the paper processing device of second embodiment with identical according to the paper processing device of first embodiment.
As mentioned above, according to second embodiment, relatively provide drive roll with transfer roller.Therefore, provide to prevent to every friction force difference that paper applies in the pile, thus the paper process mechanism of the paper that can align more accurately.
Third embodiment of the invention is different from the operation control that the first embodiment part is pair roller 601.
As shown in figure 18, when paper is sent among the terminal bookbinding processing pallet F, depend on the length of paper or curling of paper appearance, the front end of the paper that is transmitted may touch roller 601.In this case, when roller 601 rotated according to the direction opposite with paper conveyance direction, bending as shown in figure 19 may take place in paper.Therefore, when the front end of paper during by roller 601 or near roller 601, roller 601 stops or according to the direction of transfer rotation, hinders the transmission of paper to prevent roller 601.Then, roller 601 is according to rotating in the opposite direction with the sender, so that the rear end of paper falls into rear end grid 51 (referring to Figure 20).
When handling jogger grid 53 (referring to Figure 20) among the pallet F by terminal bookbinding when aliging paper, must apply conveying capacity so that paper falls into rear end grid 51 sides to paper with the vertical direction of direction of transfer.Therefore, as shown in figure 20, when the alignment paper after, roller 601 according to the sender in the opposite direction (arrow R) rotation.When the front end of paper always contacts with roller 601, it is contemplated that, exceedingly return paper according to the roller 601 that rotates in the opposite direction with the sender, thereby the rear end of paper bends.Therefore, at the front end that is entering the paper that terminal bookbinding handles pallet F by roller 601 or after near roller 601, beginning according to sender's rotation of (arrow R) in the opposite direction.Carry out contrarotation operation discontinuously, paper is exceedingly returned in the rear end grid 51 preventing.
When the end bookbinding is handled the alignment end among the pallet F and is transmitted pile downstream, as shown in figure 21, by discharging the rear end that pushes away pile on the ratchet 52a.When 601 pairs of paper of the roller that utilizes connecting gear 600 as shown in figure 22 apply conveying capacity when beginning to transmit, the transfer rate of roller 601 is arranged to be equal to or higher than the transfer rate of discharging ratchet 52a, to prevent roller 601 and to discharge ratchet 52a pile is applied load, and apply load mutually between roller 601 and the discharge ratchet 52a.
When the pile that aligns in binding processing pallet F endways is sent to displacement pallet 202, when the quantity of paper in the pile increases, is applied to the load of discharging ratchet 52a and increases.When paper when the length of direction of transfer is big, pile is easier to bend.Therefore, as shown in figure 23, discharge and utilize roller 601 that pile is sent to displacement pallet 202 pile.Can reduce the transmission load of discharging on the ratchet 52a like this, and prevent that pile from bending.When blocking or entering number of paper that terminal bookbinding handles pallet F at mission period generation paper and surpass the number of paper of regulation, detecting makes a mistake and stop paper transmitting.In this case, as shown in figure 24, connecting gear 600 rotations are moved away from the direction of pile with court, thereby allow user's handling of paper obstruction successfully.Further, connecting gear 600 can be removed from pile in order to make the user, such as, the knob 612 coaxial with cam 605 can be provided, thus can rotating cam 605 and rotation come mobile connecting gear 600.Alternatively, can provide lever 613 so that can come mobile connecting gear 600 by direct rotation.Under the situation that lever 613 is provided, if in Figure 24 operating lever 613 in the direction of the clock, can open the side that connecting gear 600 contacts with pile P so.
Figure 25 is the diagram of circuit that stops up the control process during handling.As shown in figure 25, when the beginning task was handled, at first CPU 360 stopped the processing (step S301) such as paper transmission and paper alignment operation.CPU 360 rotates predetermined amount with electrical motor M and cam 605 from initial position, thereby roller 601 is moved to ready position (step S302).CPU 360 judges whether roller 601 has moved to ready position (step S303), indicates the user to carry out then and stops up processing (step S304).By idsplay order on the operation display unit of image processing system PR, thereby carry out this instruction.
Figure 26 A and 26B are the diagram of circuits according to the whole control process among the paper processing device PD of the 3rd embodiment.
Shown in Figure 26 A, when task initiation, at first, CPU 360 checks that whether carrying out the center bookbinding handles (step S401).When carrying out center bookbinding processing, CPU 360 rotates predetermined amount with electrical motor M1 and cam 605 from initial position, thereby roller 601 is moved to ready position (step S402).CPU360 is with electrical motor M2 and turn to guide member 609 from the predetermined amount of initial position rotation, turns to drive access (step S403) thereby form.When paper enters that pallet F (step S404 is for being) is handled in terminal bookbinding and top of form arrives roller 601 or during near roller 601 (step S405 is for being), CPU 360 stop rollers 601 or press paper conveyance direction and rotate roller 601 (step S406).Through the schedule time, CPU 360 is according to rotating roller 601 (step S407) in the opposite direction with the sender after rotation.In the processing of repeating step S404 and subsequent step, CPU 360 waits for that alignment operation finishes.
When alignment operation finished (step S408 is for being), CPU 360 began to discharge the operation (step S409) of pile by discharging ratchet 52a.When top of form passes through the crack position of roller 601 (step S410), CPU 360 begins electrical motor M1 and the predetermined amount (step S411) of cam 605 rotations.When having transmitted predetermined transmission distance (step S412), the processing of CPU 360 repeating step S402 and subsequent step is up to task termination.When task termination (step S413), CPU 360 turning motor M1 and cam 605, thus roller 601 is moved to ready position (step S414).In addition, CPU 360 turning motor M2 will turn to guide member 609 to move to initial position (step S415), end process then.
On the other hand, when task in step S401 was not the center bookbinding, CPU 360 changed the diagram of circuit of Figure 26 B over to, and whether the inspection task is that (step S416) handled in terminal bookbinding.When this task was not end bookbinding processing, CPU 360 left this diagram of circuit.When task was end bookbinding processing, CPU 360 rotated predetermined amount with electrical motor M1 and cam 605 from initial position, thereby roller 601 is moved to ready position (step S417).CPU 360 will turn to guide member 609 from the predetermined amount of initial position rotation, thereby be formed into displacement pallet 202 drive access (step S418).When paper enters that pallet F (step S419 is for being) is handled in terminal bookbinding and top of form arrives roller 601 or during near roller 601 (step S420 is for being), CPU 360 stop rollers 601 or press paper conveyance direction and rotate roller 601 (step S421).Through the schedule time, CPU 360 is according to rotating roller 601 (step S422) in the opposite direction with the sender after rotation.In the processing of repeating step S419 and subsequent step, CPU 360 waits for that alignment operation finishes (step S423).
When the processing end among alignment operation end (step S423 is for being) and the end bookbinding processing pallet F (step S424), CPU 360 utilizes discharge ratchet 52a to begin to discharge the operation (step S425) of pile.When top of form process roller 601 crack positions (step S426), CPU 360 begins electrical motor M1 and the predetermined amount of cam 605 rotations, thereby roller 601 is moved to sheet transport position (step S427).When paper is discharged end (step S428), the processing of CPU 360 repeating step S419 and subsequent step is up to task termination.When task termination (step SS429), CPU 360 turning motor M1 and cam 605, thus roller 601 is moved to ready position (step S430).In addition, CPU 360 turning motor M2 will turn to guide member 609 to move to initial position (step S431), end process then.
In the above description, with the representative of roller as delivery unit.Yet, when delivery unit is belt, can obtain identical effect.
As mentioned above, according to the 3rd embodiment, in the connecting gear of paper processing device, by after the transfer roller, transfer roller contrarotation and plurality of sheets of paper fall into the rear end grid with the paper that aligns in paper conveyance direction at top of form.Therefore, the paper process mechanism paper that can align more accurately.
Fourth embodiment of the invention is different from the S. A. that the first embodiment part is the transfer roller of connecting gear 600 can regulate according to the quantity of the paper that piles up and the type of paper, and provides mobilizable transmission load-carrying element on the top of transfer roller.
As shown in figure 27, bind endways when sheet-shaped recording medium and to handle when aliging among the pallet F, connecting gear 600 is positioned at the position of roller 601 withdrawals.Finish to discharge on the ratchet 52a and to push away pile P after the alignment of sheet-shaped recording medium, use axle drive shaft 602 as the connecting gear 600 of turning cylinder to make roller 601 contact pile P then.In this case, the rotational trajectory of roller 601 changes according to the position of axle drive shaft 602.For example, as shown in figure 28, when axle drive shaft 602 was higher than pile P, the course bearing of the roller 601 of contact pile P was opposite with the direction of transfer of sheet-shaped recording medium.Therefore, the paper of sheet-shaped recording medium topmost may move in the opposite direction with the sender.Otherwise as shown in figure 29, when axle drive shaft 602 was lower than pile P, the course bearing of the roller 601 of contact pile P was identical with the direction of transfer of sheet-shaped recording medium.Therefore, the paper of sheet-shaped recording medium topmost may move up the sender.Therefore, the displacement of the sheet-shaped recording medium of generation minimized when roller 601 contacted with sheet-shaped recording medium when beginning to transmit pile P in order to make, as shown in figure 30, consider the transmissible thickness d of pile P, axle drive shaft 602 need be positioned at thickness d or approach in the scope of thickness of thickness d.In other words, roller 601 is contacted with pile P according to the direction of the upper surface that is basically perpendicular to pile P.When roller 601 contacts with pile P in this manner, can not produce component of force in the direction that is parallel to pile P upper surface.Even produced component of force, this component of force is also very little.Therefore, moving shown in Figure 28 and 29 can not take place in the sheet-shaped recording medium of pile P or pile P top layer.More particularly, if the horizontal component of power less than the friction force between the sheet-shaped recording medium surface, pile P keeps terminal bookbinding to handle aligned condition on the pallet F so.
As mentioned above, according to the 4th embodiment, can adjust the alignment force (alignment force on the direction of transfer) be applied to sheet-shaped recording medium according to the position (aligned position) that roller 601 is pushed down pile P.Therefore, state according to sheet-shaped recording medium changes alignment force, these states are such as being the type of quantity, sheet-shaped recording medium of sheet-shaped recording medium and image model (such as black and white, colour, character and pattern, and the image type of printing ratio and so on).Aligned position is roller 601 is handled pallet F to terminal bookbinding a distance.The alignment force that roller 601 is applied to sheet-shaped recording medium changes according to this distance.The aligned position of roller 601 is handled pallet F the closer to the end bookbinding, and the alignment force that is applied to sheet-shaped recording medium is big more.Under following three kinds of situations, need to adjust alignment force.
Less or when needing the paper heavier (ground paper) of alignment when the friction force of imaging surface, need to increase alignment force.Such as, when the ratio (being so-called printing ratio) of print image in the sheet-shaped recording medium was higher, friction force was less.
When the friction force of imaging surface paper big or to be alignd when light (thin paper), need reduce alignment force.Such as, when the printing ratio was low, the friction force of imaging surface was bigger.
No matter number of paper how much, all must apply stable alignment force.When number of paper more after a little while, handle the aligned in position sheet-shaped recording medium of pallet F near terminal bookbinding at roller 601.When number of paper increases, handle the aligned in position sheet-shaped recording medium of pallet F further from the end bookbinding at roller 601.
In these cases, according to the type of the type of sheet-shaped recording medium, sheet-shaped recording medium, thickness, printing ratio etc., change the grade of conveying capacity and handle the setting of the distance of pallet F to terminal bookbinding.CPU360 is according to judging this change from the various information of image processing system PR input.CPU 360 is set to the distance that pallet F is handled in terminal bookbinding, and comes rotating cam 605 to change this setting by electrical motor M1.In this case, preestablish a plurality of other distances of level according to the state of sheet-shaped recording medium, then according to any one rank of Information Selection about sheet-shaped recording medium.Can relatively easily adjust like this.
In Figure 31, when pallet F alignment sheet-shaped recording medium was handled in the end bookbinding, connecting gear 600 was positioned at the position of roller 601 withdrawals.Yet, when sheet-shaped recording medium is alignd, depending on the rolled state of sheet-shaped recording medium, the front end that enters the sheet-shaped recording medium of terminal bookbinding processing pallet F touches the roller 601 of connecting gear 600.Therefore, sheet-shaped recording medium may bend, thereby reduces the quality of alignment of pile P.Therefore, in this embodiment, touch roller 601, transmission load-carrying element 615 shown in figure 32 is provided in order to prevent sheet-shaped recording medium.Transmitting the part that front end that load-carrying element 615 can prevent the sheet-shaped recording medium that transmits and roller 601 be used to contact sheet-shaped recording medium contacts.
As shown in figure 33, when beginning to transmit sheet-shaped recording medium or having transmitted sheet-shaped recording medium, if fix at the transmission load-carrying element 615 (coaxial with roller 601) that the position near the roller 601 of connecting gear 600 provides, connecting gear 600 is around axle drive shaft 602 rotations so.Therefore, when roller 601 touches pile P, transmit load-carrying element 615 extruding pile P, and produce the transmission resistance that stops pile P.Therefore, allowing to transmit load-carrying element 615 rotates freely with respect to connecting gear 600.Thereby, as shown in figure 34, when transmitting pile P, turn to push away on the guide member 609 and transmit load-carrying element 615.Alternatively, transmitting load-carrying element 615 is made by elastomeric material.When producing excessive power (antagonistic force), transmit load-carrying element 615 elastic deformation takes place.Like this, even transmit the surface that load-carrying element 615 touches pile P, also can prevent to transmit load-carrying element 615 and produce big transmission resistance.
Transmitting load-carrying element 615 can rotate freely with respect to connecting gear 600.In Figure 32,, flexibly promote to transmit load-carrying element 615 by anticlockwise direction by such as the helix torsion coil spring.As shown in figure 33,, transmit the top of load-carrying element 615 and the preceding end in contact of pile P, touch pile P to prevent roller 601 at initial condition.Yet when transmitting pile P, the right-hand revolution that needs utilization to be pressed as shown in figure 34 by the antagonistic force from pile P side of the elastic force generation of elastic element 608 transmits load-carrying element 615, thereby allows roller 601 to touch pile P.Therefore, be arranged on and transmit in load-carrying element 615 contact pile P in initial condition the scope of front end being applied to the elastic thrust that transmits load-carrying element 615, and this elastic thrust allows roller 601 to contact with pile P when transmission pile P.When utilize transmitting the elasticity of load-carrying element 615 itself, elastic thrust is set in the same way.
When pressing direction of transfer alignment sheet-shaped recording medium in binding processing pallet F endways, as shown in figure 36, sheet-shaped recording medium is return according to rear end grid 51 directions by outlet roller 616 and is alignd.Yet, when the conveying capacity that utilizes outlet roller 616 is return the power of sheet-shaped recording medium when not enough according to rear end grid 51 directions, as shown in figure 37, also can return sheet-shaped recording medium according to the rotation of the roller 601 of connecting gear 600.
When returning sheet-shaped recording medium by the roller 601 of contrarotation connecting gear 600 according to rear end grid 51 directions as shown in figure 37, can be according to the rotation amount of the axle drive shaft 602 of connecting gear 600, control roll 601 touches the power of sheet-shaped recording medium.When returning sheet-shaped recording medium according to rear end grid 51 directions according to the rotation of the roller 601 of connecting gear 600, also can be by the roller 601 of rotary transfer mechanism 600 discontinuously, control roll 601 is applied to the conveying capacity of sheet-shaped recording medium.In addition, can carry out this control to being sent to terminal each sheet-shaped recording medium of bookbinding processing pallet F.Yet, even consider the life-span of the axle drive shaft 602 of connecting gear 600, and every a plurality of paper are carried out this control, also can return sheet-shaped recording medium and the sheet-shaped recording medium of aliging according to rear end grid 51 directions.According to this control, can prevent that sheet-shaped recording medium from excessively returning and improve quality of alignment.
When sheet-shaped recording medium returned to rear end grid 51 by the roller 601 of connecting gear 600 and aligns, roller 601 was applied to the conveying capacity of necessity of sheet-shaped recording medium according to depending on that the friction force of the lip-deep image state of sheet-shaped recording medium changes.The position that roller 601 and sheet-shaped recording medium contact with each other changes according to the quantity of sheet-shaped recording medium, the thickness of sheet-shaped recording medium etc.Therefore, obtain image state from image processing system PR, this image state is such as the ratio that is image in color mode or monochromatic mode and the sheet-shaped recording medium.When the friction force of considering the sheet-shaped recording medium surface based on this information hour, increase the power of roller 601 contact sheet-shaped recording medium.Also can from the signal of the sheet-shaped recording medium sensor of image processing system or paper processing device etc., obtain such as the quantity of sheet-shaped recording medium and the information the thickness.Like this, can adjust the position of roller 601 contact sheet-shaped recording medium according to these information.The position of roller 601 contact sheet-shaped recording medium can be the position of predefined state when being in the shipment product, perhaps can be provided with or adjust after shipment.
When the sheet-shaped recording medium of aliging in will binding processing pallet F endways is sent to center bookbinding and folding processing pallet G, as shown in figure 38, pile P pushes away by discharging on the ratchet 52a, and send into the roller 601 of connecting gear 600 and the crack that forms with respect to the drive roll 614 of roller 601 in.In this case, thick pile P enters in the narrow crack between roller 601 and the drive roll 614.Like this, roller may stay trace at the front end of pile P, perhaps destroys the aligned condition of pile P.
Like this, shown in Figure 39 and 40, discharge the pile that pushes away on the ratchet 52a through registration process.The front end of sheet-shaped recording medium is opened the roller 601 of connecting gear 600 and with respect to the crack between the drive roll 614 of roller 601.The front end of sheet-shaped recording medium is by after the crack of opening, and roller 601 touches sheet-shaped recording medium, thereby utilizes roller 601 and drive roll 614 to transmit sheet-shaped recording medium.
Depend on that the lip-deep friction force of sheet-shaped recording medium may be low excessively from the image state of the sheet-shaped recording medium of image processing system PR transmission.In this case, when the sheet-shaped recording medium of alignment formed pile, the friction force between the sheet-shaped recording medium was less.Like this, when the roller 601 of connecting gear 600 transmits pile P, as shown in figure 41, may not transmit the sheet-shaped recording medium of pile P front and rear surfaces inboard, thus these sheet-shaped recording medium stop or may according to sender's landing in the opposite direction.Therefore, even discharge as shown in figure 42 after the position of shifting the crack that forms by the roller 601 of connecting gear 600 with respect to the drive roll 614 of roller 601 on the rear end of ratchet 52a with pile P onto, as shown in figure 43, in the rear end of supporting sheet-shaped recording medium, with the speed moving sheet recording medium identical with the speed of the transmission of being undertaken by roller 601 and drive roll 614.Can transmit pile P stably like this.
In this case, even discharge the transfer rate of the operating speed of ratchet 52a, discharge ratchet 52a and also may be recessed into the rear end of pile P, thereby on sheet-shaped recording medium, cause cut a little more than roller 601.Therefore, the operating speed of discharge ratchet 52a can be arranged to be lower than the transfer rate of pile P.If the time that discharge ratchet 52a begins to move is different with the time opening of the transmission of pile P, formed the gap because discharge between ratchet 52a and the pile P, so also can prevent from pile P, to produce cut.Alternatively, can cause when discharging ratchet 52a that discharging ratchet 52a operates from the rear end of pile P fixed range.In this case, when the conveying capacity of roller 601 descends and pile P when moving down, discharge the conveying capacity of ratchet 52a and can add on the pile P.
In the rear end of discharging ratchet P support pile P, by roller 601 or connecting gear 600 and drive roll 614 transmission pile P.In this case, discharge ratchet 52a and need support the rear end of pile P till having transmitted pile P stably.Therefore, when connecting gear 600, roller 601 or the like had hindered the operation trace of discharge ratchet 52a, the operation of discharging ratchet 52a must stop before roller 601 has transmitted pile P fully.The result causes and can not transmit pile stably.Therefore, in this embodiment, as shown in figure 44, no matter connecting gear 600 has which kind of position and attitude, and connecting gear 600 does not hinder the operation trace of discharging ratchet 52a.
In Figure 44, connecting gear 600 comprises: discharging belt conveyor 52 both sides separately and be provided at terminal bookbinding and handle pair of rolls 601 on two faces of pallet F; The pulley 601a that provides via roller S. A. 601b is positioned at terminal bookbinding and handles the pallet F outside respectively, and is coaxial with roller 601; Via the rotatably whole bonded assembly axle drive shaft of coupking shaft 602c pulley 602a; Support the arm 604 of pulley 601a and axle drive shaft pulley 602a; And cover speed belt 603a between pulley 601a and the axle drive shaft pulley 602a.In addition, connecting gear 600 comprises: the axle drive shaft pulley 602b that the electrical motor (not shown) drives is used to drive axle drive shaft pulley 602a; And speed belt 603b, be used for the propulsive effort of axle drive shaft pulley 602b is delivered to axle drive shaft pulley 602a.Coupking shaft 602c leaves end-face-bookbinding and handles pallet F one segment distance, to prevent to hinder discharge ratchet 52a.Adopt this structure, the part above the partial sum between the roller 601 vertically is arranged in end-face-bookbinding processing pallet F has been guaranteed enough to prevent to hinder the space of discharging ratchet 52a, discharges the part of ratchet 52a between roller 601 and moves.Thereby the operation of discharging ratchet 52a is not interrupted.
When connecting gear 600 structures as shown in figure 44 the time, axle drive shaft pulley 602b is as the turning cylinder of connecting gear 600.If axle drive shaft pulley 602b is arranged to be positioned at the scope of the thickness d of pile P shown in Figure 30, perhaps approach in the scope of thickness of thickness d, so as described above, sheet-shaped recording medium can not be shifted.Even sheet-shaped recording medium is shifted, it is also minimum to be shifted.
As shown in figure 45, when thick pile P when turning to the knuckle section between guide member 609 and the distributing roller 56, difference takes place to transmit between pile P inboard and outside sheet-shaped recording medium.Therefore, the front end of sheet-shaped recording medium enter be positioned at connecting gear 600 and distributing roller 56 downstreams the pile transfer roller to 71.After this, when roller 601, drive roll 614 and pile transfer roller by connecting gear 600 continue to transmit pile P to 71, leave the pile P that transmits difference and continue to transmit to 71, and difference is not transmitted in the rear end of the sheet-shaped recording medium P that transmits by roller 601 and drive roll 614 by the pile transfer roller.Therefore, as shown in figure 46, the outside of pile P begins in knuckle section crooked.Therefore, when keeping this state to transmit pile P, situations such as wrinkling may take place in pile.
In order to prevent this phenomenon, under the situation of the sheet-shaped recording medium that transmits fixed qty, after the pile transfer roller begins to transmit pile P to 71, discharge the transmission of being undertaken by connecting gear 600.Like this, because the transmission difference that is taken place during deflection pile P (along turning to guide member 609) in knuckle section appears at the rear end of pile P naturally, so can eliminate crooked and wrinkling.
The transmission difference that pile P takes place during by knuckle section is different and different according to the thickness of pile P.Usually, the thick more transmission difference of pile P is big more.When the zone that coloured image in the sheet-shaped recording medium or image occupy was big, the lip-deep friction force of sheet-shaped recording medium descended.Like this, the friction force between the sheet-shaped recording medium also descends, and has the increase of the shift amount between the sheet-shaped recording medium in the drive access that turns to of bigger transmission resistance.Therefore, when from about the information prediction of image state to the displacement quantitative change when big, the roller 601 of connecting gear 600 is separated and the timing that stops to apply conveying capacity is arranged to than acquiescence regularly more earlier from pile P.When from the thickness of judging pile P such as the quantity and the information the thickness of sheet-shaped recording medium when big,, roller 601 is separated and the timing that stops to apply conveying capacity is arranged to than acquiescence regularly more earlier from pile P according to above-mentioned same mode.
According to this control, because sheet-shaped recording medium is not transmitted the influence of difference, so can eliminate crooked and wrinkling.
The displacement that takes place when the front end of sheet-shaped recording medium enters pile transfer roller 71 (displacement that is caused by the transmission difference that turns between guide member 609 inboards and the outside and by roller 601, drive roll 614 and pile between the displacement that causes of the slip that takes place) is depended on the state (type of number of paper, recording medium, image model, printing ratio etc.) of sheet-shaped recording medium and is increased or reduce.Therefore, can imagine, when reducing the conveying capacity of roller 601, that is, when the timing that separates with pile at roller 601 is set to more earlier, adjust the conveying capacity (after making roller 601 and sheet-shaped recording medium contacting, the timing that roller 601 is separated with pile) of roller 601.In both cases, the front end displacement is bigger.When pile thickness was big, the transmission difference between the knuckle section inboard and the outside increased.When the friction force on the imaging surface hour (when image occupies than large tracts of land in sheet-shaped recording medium), because slide easily between roller 601 and the sheet-shaped recording medium, so the increase of the shift amount of pile front end.Clearly, be mixed with in sheet-shaped recording medium such as, ground paper more and when image-region was big in the sheet-shaped recording medium, pile thickness also can increase, and takes place than major coil easily usually when number of paper.
Figure 47 is the diagram of circuit of the control process carried out by control unit 350 during the initial treatment in connecting gear 600 and knuckle section.Control process hereto, the CPU 360 of control unit 350 utilizes the RAM (not shown) to carry out the program that is stored in the RAM (not shown) as the work area.
In the diagram of circuit of Figure 47, at first, CPU 360 checks whether the cam 605 of connecting gear 600 is positioned at initial position (step S501).When cam 605 was not positioned at initial position, CPU 360 driving motor M1 moved to initial position (step S502) with cam 605.When cam 605 was positioned at initial position, CPU 360 checked to turn to guide member 609 whether to be positioned at initial position (step S503).When turning to guide member 609 not to be positioned at initial position, CPU 360 driving motor M2 will turn to guide member 609 to navigate to initial position (step S504).CPU 360 is positioning cam 605 and turn to guide member 609 and finish initial treatment by this way.
Figure 48 A is the diagram of circuit of the whole control process of paper processing device PD among this embodiment to 48C.Though diagram of circuit is divided into three figure, in these figure, has shown a treating process.
In Figure 48 A, when task initiation, at first CPU 360 checks whether (step S601) handled in implementation center's bookbinding.When implementation center's bookbinding is handled (step S601 is for being), CPU 360 rotates predetermined amount with electrical motor M1 and cam 605 from initial position, thereby roller 601 is moved to ready position (step S602), with electrical motor M2 and the amount that turns to guide member 609 to be scheduled to, turn to drive access (step S603) then thereby form from the initial position rotation.When sheet-shaped recording medium is discharged to terminal bookbinding processing pallet F, CPU 360 is according to rotating roller 601 (step S604) in the opposite direction continuously with the sender or according to rotating roller 601 (step S605) in the opposite direction discontinuously with the sender, with driving motor M1 and cam 605, and roller 601 is contacted with the every lamellar recording medium that transmits, thereby alignment sheet-shaped recording medium (step S606 and S608).Alternatively, after the processing of step S604, among the step S607, CPU 360 driving motor M1 and cam 605, so that roller 601 contacts with the sheet-shaped recording medium of the transmission of every predetermined quantity, and the alignment sheet-shaped recording medium.
After the processing of step S606, S607 and S608, CPU 360 driving motor M1 and cam 605 make roller 601 move to ready position (step S609).When the processing among the end bookbinding processing pallet F finishes (step S610 is for being), CPU 360 utilizes discharge ratchet 52a to begin the discharge (step S611) of pile.On the other hand, when processing does not finish (step S610 is for denying), CPU 360 gets back to step S604 or step S605, and repeats the operation corresponding to the transmission of next sheet-shaped recording medium.
After step S611 began to utilize the pile of discharging ratchet 52a to discharge, CPU 360 checked whether the front end of sheet-shaped recording medium has passed through the crack position (step S612) of roller 601.When the front end of sheet-shaped recording medium had passed through the crack position, CPU 360 stopped by discharging the transmission (step S613) that ratchet 52a carries out, and then with electrical motor M1 and the predetermined amount of cam 605 rotations, thereby roller 601 was moved (step S614) to direction of transfer.Subsequently, CPU 360 rotation rollers 601 are with the transmission (step S615) of beginning pile and begin to discharge the operation (step S616) of ratchet 52a at direction of transfer.Alternatively, after step S614, CPU 360 begins to discharge the operation (step S617) of ratchet 52a in the rotation of beginning roller 601.Alternatively, CPU 360 begins through beginning to discharge the operation (step S618) of ratchet 52a after the schedule time in the rotation from roller 601.At step S617, CPU 360 begins to discharge the operation of ratchet 52a with the operating speed of the transfer rate that is equal to or higher than roller 601.
The processing of the arbitrary step in having carried out step S616, S617 and S618 and when sheet-shaped recording medium having been transmitted preset distance (step S619), CPU 360 driving motor M1 and cam 605 make roller 601 move to ready position, and make roller 601 leave pile P (step S620).CPU 360 carries out these a series of operations up to task termination.When task termination (step S621), CPU 360 turning motor M1 and cam 605, and make roller 601 move to initial position (step S622) are with electrical motor M2 with turn to guide member 609 to move to initial position (step S623), end process then.
On the other hand, when task among the step S601 is not center bookbinding processing (step S601 is for denying), whether CPU 360 inspection tasks are terminal bookbinding processing (step S624).When task is end bookbinding processing (step S624 is for being), CPU 360 rotates predetermined amount with electrical motor M1 and cam 605 from initial position, makes roller 601 move to ready position (step S625).Subsequently, CPU 360 is with electrical motor M2 and turn to guide member 609 from the predetermined amount of initial position rotation, thereby is formed into the drive access (step S626) of displacement pallet 202.As mentioned above, this drive access is the path that forms between outside face that turns to guide member 609 and guide plate 611.
When being formed into the guide path of displacement pallet 202 at step S626,360 couples of CPU are discharged to terminal bookbinding and handle each sheet-shaped recording medium on the pallet F by opposite spin roller 601, beginning alignment operation (step S627).CPU 360 driving motor M1 and cam 605 make roller 601 touch each sheet-shaped recording medium (step S629) of transmission.Alternatively, CPU 360 driving motor M1 and cam 605 make roller 601 contact the sheet-shaped recording medium of the transmission of every predetermined quantity, and the sheet-shaped recording medium (step S630) of aliging.After the processing of step S626, when sheet-shaped recording medium was discharged to terminal bookbinding processing pallet F, CPU 360 made roller 601 according to continuing rotation (step S628) in the opposite direction discontinuously with the sender.CPU 360 driving motor M1 and cam 605 make the sheet-shaped recording medium of roller 601 each transmission of contact, and the sheet-shaped recording medium (step S631) of aliging.
After the processing of arbitrary step, CPU 360 driving motor M1 and cam 605 make roller 601 move to ready position (step S632) in step S629, S630 and S631.When the processing among the end bookbinding processing pallet F finishes (step S633), CPU 360 utilizes discharge ratchet 52a to begin the discharge (step S634) of pile P.Transmitted the time point (step S635) of preset distance at pile P, when task is finished (step S636 is for being), CPU 360 turning motor M1 and cam 605 make roller 601 move to initial position (step S622).CPU 360 is further with electrical motor M2 and turn to guide member 609 to move to initial position (step S623), end process then.When task is not finished (step S636 is for denying), CPU 360 gets back to step S625, and the processing of repeating step S625 and subsequent step, up to task termination.
On the other hand, when task in step S624 is not end bookbinding processing, the processing of CPU 360 direct process ends figure.
As mentioned above, according to the 4th embodiment, in the connecting gear of paper processing device, can adjust the S. A. of transfer roller and mobilizable transmission load-carrying element is provided on the transfer roller top.Therefore, the paper process mechanism paper that can align more accurately.
As indicated above, according to embodiments of the invention, by turning to drive access and the delivery unit that pile applies conveying capacity being transmitted pile at upstream side.Therefore, can under the situation that keeps the pile aligned condition, transmit pile.
Delivery unit applies conveying capacity to the outside that turns to the pile that transmits on the drive access.Therefore, when binding drive access that processing unit is connected to the bending of center bookbinding processing unit when uploading the paper feeding heap, solved and be not easy conveying capacity is delivered to problem on the paper in the pile outside, and outside paper transmits the problem of difference than the easier appearance of inboard paper.Can under the situation that keeps the pile aligned condition, transmit pile.
Delivery unit can move at least two positions, that is, delivery unit applies the position of conveying capacity and delivery unit does not apply position from conveying capacity to pile to pile.Like this, delivery unit does not hinder the alignment of pile.When detecting wrong such as paper blocks, because delivery unit can be discharged into delivery unit does not apply position from conveying capacity to pile, the user can easily stop up processing.
Apply the axle drive shaft of propulsive effort and the delivery unit rotating shaft coaxle in moving to delivery unit.Therefore, the structure of paper processing device is simplified, thereby neither can cause the assembling capacity variation, also can not increase the cost of product.Further, not need according to the mobile in the opposite direction paper of sender with towards the terminal grid bump paper rear end and the paper that aligns.
Even the position that delivery unit can be withdrawn is arranged on when the paper sheet thickness of accessible pile in the terminal bookbinding processing unit and number of paper reach maximum, delivery unit also can not hinder the position of the transmission of pile.Therefore, be not in contact with one another between pile front end and the delivery unit, and the pile front end can not be subjected to cut, folding line equivalent damage.
The position that delivery unit can be withdrawn is arranged on the position that delivery unit can not hinder the transmission of pile according to the quantity of the paper of the pile of binding processing unit for processing such as end and the information the type.Therefore, no matter the quantity of the paper of alignment how much, can be provided with identical operations time and capacity rating and can not descend.Further, can prevent transmission problem such as paper bending.
It is movable that formation turns to the transmission load-carrying element of drive access, even and when pile when end bookbinding processing unit is sent to stack device, also by transmitting load-carrying element guiding pile.Therefore, the structure of paper processing device is simplified, thereby neither can cause product assembling capacity variation, also can not increase cost of product.Further, different though the friction force state between the paper depends on number of paper, paper quality, print state etc., connecting gear can be according to number of paper, paper quality, and print state etc. are automatically adjusted the conveying capacity that is used to transmit pile.Thereby can improve delivery quality.
When delivery unit applied conveying capacity to pile, pile was thick more, and the conveying capacity that applies is big more.Therefore, can increase the conveying capacity of transmission pile more for a long time when number of paper.When pile is sent to the crooked drive access that is connected to center bookbinding processing unit from the bookbinding processing unit, and bind processing unit when being delivered on the stack device from end, can guarantee enough big conveying capacity when pile.
When pile is delivered to the crooked drive access that is connected to center bookbinding processing unit from binding processing unit, if the transfer rate of pile is lower than the transfer rate of the discharge ratchet that is used for pushing away the paper rear end, pile may become curved or the paper rear end may be subjected to cut, folding line equivalent damage so.Yet,, can prevent these damages because the transfer rate of connecting gear is arranged to be higher than the transfer rate of discharging ratchet.
The shape that is right after at the transmission load-carrying element before the roller of the delivery unit that applies conveying capacity to pile makes that the angle of contact between this roller and the pile front end is comparatively mild.Like this, even when top of form takes place than major coil, because can reduce crimping portion and apply angle of contact between the roller of delivery unit of conveying capacity, so top of form can not be subjected to cut, folding line equivalent damage.
When pile from the bookbinding processing unit when being sent to stack device, iff by on push away the paper rear end the discharge ratchet discharge pile, pile may become curved and can't discharge so.Yet,, can prevent bending and obstruction because use this connecting gear simultaneously.When detecting wrong such as stopping up, the user can remove paper easily.
When forming pile when the paper with less surperficial friction or by the paper that image has reduced surperficial friction, iff the paper outside is applied conveying capacity, conveying capacity may not can be delivered to the inboard so, thereby only can transmit the paper in the outside.Yet,, can transmit paper together, and can between paper, not produce slip by applying conveying capacity from the inboard simultaneously.
Though having utilized specific embodiment makes complete and clearly description to the present invention, but therefore appended claim is not subjected to the restriction of embodiment, appended claim should be interpreted as to comprise those skilled in the art make clearly fall into the whole modifications in the basic teachings of the present invention and replace structure.
