Then, the control system of image processing system and sheet post-process apparatus is carried out simple explanation.Fig. 3 is the schematic block diagram of the control system of image processing system and sheet post-process apparatus.
The control part 310 of sheet post-process apparatus 4 is controlled the action of inlet roller 61, branch components 62, carrying roller 63, accessory 70, stack portion 90, attachment means 110, fold mechanism 120, lateral alignment parts 100 based on the indication of master control part 300.
Fig. 4 is the skeleton diagram that is used to illustrate stack portion 90.Fig. 5 is the skeleton diagram that is used to illustrate that the arrow A direction from Fig. 4 of lateral alignment parts 100 is watched.
As shown in Figure 4, stack portion 90 has stacker 91, stackable unit 92, drive division 95.Stacker 91 is caught the lower end of paper.Stackable unit 92 support stack devices 91.Drive division 95 moves up and down stackable unit 92.Drive division 95 has guide rail 96, pulley 97, belt 98 and electrical motor M1.Guide rail 96 is along the conveyance direction of the paper stackable unit 92 that leads up and down.Belt 98 is reeled to be supported on the pulley 97.Belt 98 is connected in stackable unit 92.Electrical motor M1 makes belt 98 rotations via pulley 97.Belt 98 moves stackable unit 92.Electrical motor M1 can be a stepper motor.
First detecting unit 93 detects the position of stacker 91.First detecting unit 93 can be for example microsensor, micro-actuator etc.In the present embodiment, first detecting unit 93 detects the original position (below be a HP) of stackable unit 92.With a HP is benchmark, controls moving up and down of stacker 91 by giving the pulse count that is used for drive electric motor M1.As an example, in the present embodiment, the paper that stacker 91 comes conveyance remains on the position (position of readiness of stacker 91) of the middle body arrival gutter pos in the above-below direction.Stacker 91 has paper lower end detecting unit 99, is used to detect the lower end arrival stacker 91 of paper.Paper lower end detecting unit 99 can be for example microsensor, micro-actuator.
As shown in Figure 5, loading part 80 has lateral alignment parts 100 above stack portion 90.Lateral alignment parts 100 have align unit 102a and 102b, crossbearer parts 104a and 104b, miniature gears 106, electrical motor M2.
It is relative that align unit 102a and 102b are parallel to each other, and alignd in the end (horizontal end) of the Width that is loaded in the paper on the stack portion 90.
Then, with reference to Fig. 6 a-Fig. 6 d the action of lateral alignment parts 100 is described.Fig. 6 a-Fig. 6 d shows the state that align unit 102a and 102b are positioned at primary importance.Under the central corresponding to state of the Width of the paper P1 that the central authorities and the conveyance at the interval of align unit 102a and 102b comes, the conveyance paper is desirable conveyance posture.Align unit 102a and 102b are in the primary importance standby of horizontal end first distance of leaving paper P1 (with desirable conveyance posture by conveyance).First distance can be 15mm for example.Primary importance can be the 2nd HP.Primary importance also can be to make its rotation by giving the predetermined pulse count of electrical motor M2, and align unit 102a and 102b are from position that the 2nd HP moves.
After carrying out lateral alignment, shown in the arrow C of Fig. 6 c, align unit 102a and 102b move to the 3rd position of horizontal end the 3rd distance of leaving paper.Align unit 102a and 102b are at the follow-up paper P2 of the 3rd location pending.The 3rd distance can be shorter than first distance.The 3rd distance can be 3mm for example.
(lateral alignment action embodiment) describes the action of lateral alignment parts 100 with reference to Fig. 7 and Fig. 8.Fig. 7 is that diagram of circuit, Fig. 8 of being used to illustrate the action of lateral alignment parts 100 is the sequential chart of each parts of the diagram of circuit of corresponding diagram 7.
By folding etc. the indication of the input paper quantity of piling up in operated key 7, bookbinding and by initiating key, in 701, the master control part 300 of image processing system 1 makes the driving of control part 310 beginning electrical motor M1, M2.
In 702, stacker 91 moves to the position of readiness of stacker 91. Align unit 102a and 102b move to primary importance.If stacker 91 has been positioned at the position of readiness of stacker 91, do not turn round at 701 electrical motor M1, stacker 91 does not move, and waits for paper.If align unit 102a and 102b have been positioned at primary importance, do not turn round at 701 electrical motor M2, align unit 102a and 102b do not move, and wait for paper.
In 703,, will export from low level (low level) and bring up to high level (high level) when taking out of roller sensor 65 when detecting by the front end of the paper of carrying roller 63 conveyances.Then, when taking out of roller sensor 65 when detecting the rear end of paper, in 704, will export and be reduced to low level from high level.
In 705, beginning through after the schedule time from the output reduction of taking out of roller sensor 65, in 706, control part 310 makes accessory 70 and paper butt.This schedule time can be preestablished, so that help roll 73 is to the paper butt that is come by conveyance.Control part 310 also can make accessory 70 and paper butt reducing beginning after the driving motor of carrying roller 63 is given predefined pulse count from the output of taking out of roller sensor 65.
In 707, wait for from accessory 70 and paper butt beginning through the schedule time.This schedule time can be to begin till give predetermined pulse count to the driving motor of carrying roller 63 from accessory 70 and paper butt.In 720, total number N of the paper during whether control part 310 judgment value M pile up less than paper.Value M is the integer more than or equal to 2.Total number N (720 for being) of the paper during if value M piles up less than paper, in 725, value q substitution parameter m.Value q is the integer smaller or equal to value M.Value q can be value M half, value M 1/3, calculate according to value M.If value M is not less than total number N (720 for not) of the paper of paper in piling up, in 730, value r substitution parameter m.Value r is the integer less than value q.
In 708, control part 310 judges whether paper is last paper more than or equal to m before that paper is piled up.Last paper more than or equal to m (708 for being) before that if paper is a paper to be piled up, in 709, value j substitution parameter i.Value j is the integer more than or equal to 1.
On the other hand, if last paper more than or equal to m (708 for denying) before that paper is not a paper to be piled up, in 710, value k substitution parameter i.Value k is than j big 2 or 2 above integers.Value k can be preestablished.Value k also can the person of being to use set.
Value M, value r and value q can be preestablished respectively.Value M, value r and value q also can the person of being to use set.
For example, if value M is 0, control part 310 does not move 730.Because value q is smaller or equal to value M, institute thinks 0.In 708, control part 310 judge paper whether be paper pile up last before more than or equal to 0 paper (that is, last).
For example, if value M is 2, value q is 2, value r is 0, under the situation of the total N of the paper that paper is piled up, in 725, be 0 value r substitution parameter m smaller or equal to 2 (N=2,1).In 708, control part 310 judge paper whether be paper pile up last before more than or equal to 0 paper (that is, last).The total N of the paper of piling up at paper be not below or equal to 2 (N=3,4,5 ...) situation under, in 730, be 2 value q substitution parameter m.In 708, control part 310 judge paper whether be paper pile up last before more than or equal to 2 paper.If the total N of the paper that paper is piled up is 3,, three paper all to carry out k time lateral alignment whenever being loaded on the stacker 91 separately.If the total N of the paper that paper is piled up is 4, when being loaded on the stacker 91, the 1st paper carries out j time lateral alignment, whenever being loaded on the stacker 91 separately, remaining three paper all to carry out k time lateral alignment.
In 711, align unit 102 begins to move to the second place from primary importance for the lateral alignment paper.That is, begin to give electrical motor M2 with pulse.
In 712, control part 310 confirm accessory 70 whether with the paper butt.If accessory 70 and paper butt in 713, are beginning through after the schedule time from pulse being given electrical motor M2 (711), control part 310 makes accessory 70 leave paper.In the present embodiment, in 711, also can begin during arriving the second place, to make accessory 70 leave paper from beginning to move at align unit 102.When accessory 70 left paper, align unit 102 carried out lateral alignment.That is, this schedule time can be shorter from beginning to move the time begin to arriving during the second place than alignment parts 102.And align unit 102 arrives the second place can leave paper simultaneously with accessory 70.Accessory 70 leaves paper can be more late than the alignment parts 102 arrival second places.
In 714, after lateral alignment, control part 310 makes align unit 102 move to the 3rd position from the second place.
In 715, control part 310 deducts 1 from parameter i.In 716, confirm whether parameter is 0.If parameter i is not 0 (716 for denying), turn back to 711 in order to carry out lateral alignment once more.
If parameter i is 0 (716 for being), in 717, control part 310 judge follow-up paper whether be paper pile up last.In 717,, just turn back to 703 if follow-up paper is not a paper last (717 for not) of piling up.Align unit 102 stops in the 3rd position.On the other hand, in 717, if follow-up paper is a paper last (717 for being) of piling up, in 718, attachment means 110 bookbinding paper are piled up, and fold mechanism 120 folded sheets are piled up.This paper is piled up and is piled up loading pallet 500 discharges to paper.
After bookbinding was folding, in 719, whether control part 310 affirmations have folded by the paper of importing quantity before the initiating key in operated key 7 was piled up.If control part 310 is judged the paper that does not have all folding input quantity and is piled up (719 is not), returns 702.Align unit 102 does not stop in the 3rd position, moves to primary importance in 702.
On the other hand, pile up (719 for being), finish action at loading part 80 if control part 310 is judged the paper of all folding input quantity.The judgement whether paper of folding input quantity is piled up to be not limited to bookbinding and folding after, also can carry out in bookbinding that last paper from beginning by initiating key operated key 7 to finish is piled up, during folding.
And the triggering of the action of each parts (trigger) is not limited to take out of the reduction of the output of roller sensor 65.For example, the rising of taking out of the output of roller sensor 65 also can be used as triggering.Accessory 70 is with the paper butt or leave and also can be used as triggering.The output of paper lower end detecting unit 99 also can be used as triggering.In order to produce triggering, control part 310 can have the time meter (timer) that is used for timing.For various antiquarians, the beginning of the action of each parts and the time relationship of triggering can preestablish by calculating, test etc., and are kept at the reservoir of control part 310.
The position of readiness of stacker 91 is difference owing to the various antiquarians of image processing system 1 appointment.Therefore, from 706 to 713, accessory 70 and paper can corresponding antiquarians and set respectively from abutting to time during leaving.
If take out of a piece of paper to loading part 80, Fig. 7 704 in, take out of roller sensor 65 and detect the conveyance speed that can slow down after the rear end of paper.For example, a piece of paper of piling up of paper is discharged to the pallet 82 that piles up that is not placed with paper.It is less with the friction of paper to pile up pallet 82.The conveyance speed of a piece of paper if slow down can prevent to fly out to the top of piling up pallet 82 from taking out of the paper that roller 64 takes out of.Because it is bigger to pile up the friction that is placed with paper and paper and paper on the pallet 82, so the conveyance speed of the later paper of second paper of need not slowing down.
The number of times of lateral alignment can increase along with the increase of paper number.For example, the preceding two pieces of paper of last paper can carry out twice lateral alignment when being loaded on the stacker 91, can carry out three times lateral alignment when paper loading is on stacker 91 at last.
Therefore, by carrying out repeatedly lateral alignment under the state that in the end paper is loaded, must carry out repeatedly lateral alignment to whole paper.After finishing the lateral alignment of last paper, bind and fold.For example, if last paper is carried out repeatedly lateral alignment, just do not need to wait for that paper is from image processing system 1 discharge.For example, by carrying out lateral alignment twice under the state that only in the end paper is loaded, can reduce the influence that postpones as far as possible, and can pile up paper and carry out suitable alignment.
Carry out repeatedly lateral alignment when in the end the paper loading beyond the paper is on stacker 91.Can compare paper before the last paper that is loaded on the stacker 91 to carry out the number of times (first number) of lateral alignment many being loaded in number of times (second number) that last paper on the stacker 91 carries out lateral alignment.
Can change the second place according to the number of times of lateral alignment.For example, if when k=3, carry out 711 to 716, during i=3, distance between second place align unit 102a and align unit 102b can be second distance, during i=2, distance between second place align unit 102a and align unit 102b can be and ratio three distance narrow four distance wideer than second distance, and during i=1, the distance between second place align unit 102a and align unit 102b can be five distance narrower than second distance.
For example, if when k=3, carry out 711 to 716, during i=3, distance between second place align unit 102a and align unit 102b can be the 4th distance, during i=2, distance between second place align unit 102a and align unit 102b can be the 5th distance, and during i=1, the distance between second place align unit 102a and align unit 102b can be second distance.
(variation of lateral alignment action)
In 708, control part 310 judges whether paper is last paper smaller or equal to m before that paper is piled up, and value M and value q can be more than or equal to 1.Perhaps being worth M can be more than or equal to 2.
For example, if value M is 2, value q is 2, value r is 0, under the situation of paper sum N that paper is piled up, in 725, will be 0 value r substitution parameter m smaller or equal to 2 (N=2,1).In 708, control part 310 judge paper whether be paper pile up last before smaller or equal to 0 paper.Paper pile up last before smaller or equal to 0 paper (that is, last), in 708, control part 310 judges it is not any one.The paper sum N that piles up at paper as many as equal 2 (N=3,4,5 ...) situation under, in 730, will be 2 value q substitution parameter m.In 708, control part 310 judge paper whether be paper pile up last before smaller or equal to 2 paper.If the paper that paper is piled up sum N is 3, when being loaded on the stacker 91, a piece of paper carries out j time lateral alignment, whenever being loaded on the stacker 91 separately, remaining two pieces of paper all to carry out k time lateral alignment.If the paper that paper is piled up sum N is 4, when a piece of paper is loaded on the stacker 91 and when second paper is loaded on the stacker 91, carry out j time lateral alignment respectively, all will carry out k time lateral alignment whenever remaining two pieces of paper are loaded on the stacker 91 separately.
Pile up under the situation of easy alignment thereby reduce paper,, can save the time of lateral alignment if the sum that value m piles up than paper is big at the paper number that paper is piled up.
(first embodiment of accessory and pressing component) describes accessory 70 and pressing component 130.Fig. 9 is the section drawing of accessory 70 and pressing component 130.Figure 10 is the oblique drawing of accessory 70 and pressing component 130.
