Description
The application be that May 23, application number in 2008 are 200810098311.0 the applying date, denomination of invention divides an application for the application of " sheet handling device and image forming apparatus ".
Technical field
The present invention relates to a kind of can be to the sheet handling device and the image forming apparatus that is provided with this sheet handling device of thin slice Shu Jinhang bookbinding.
Background technology
Traditionally, in like image forming apparatus such as duplicator, chopping machine and laser beam printers, sheet handling device is arranged.In sheet handling device, for example,, the image forming apparatus main body binding after collecting the thin slice that has been formed with image on it in order.In sheet handling device, be necessary that between thin slice bundle (operation) for example, the time gap between first thin slice of last thin slice of the last operation that transmits from image forming apparatus and next operation carries out like post-processings such as bookbindings.Yet, when a plurality of position of bookbinding, except the bookbinding time, need the long period to move attachment means, thereby prolonged the bookbinding processing time.Therefore, need to prolong thin slice bundle (operation) at interval, thereby reduced the capacity rating of image forming apparatus.
Under the situation that the distance between the thin slice that transmits from image forming apparatus broadens, for becoming a branch of situation with a small amount of thin slice, capacity rating significantly reduces in the thin slice interfascicular.For example, have 100 thin slices/minute the image forming apparatus of capacity rating in, when thin slice interfascicular in bookbinding is handled when broadening 0.2s, relatively become a branch of and the reduction that becomes a branch of capacity rating with 100 thin slices with 2 thin slices.Confirm capacity rating CPM by following formula.Here, capacity rating refers to the thin slice quantity that per minute can be printed.
CPM＝60/((60/cpm)×a+b)/a)
Cpm (copy per minute): image forming apparatus capacity rating (the duplicating quantity of per minute)
A: every intrafascicular thin slice quantity
B: bookbinding processing time
In this formula, total time-write interval of image forming apparatus adds the bookbinding processing time, and the value of addition is divided by every intrafascicular thin slice quantity, thus the average preformance of definite thin slice bundle.
As using the formula result calculated, become at two thin slices that capacity rating becomes 85.7cpm under a branch of situation, become at 100 thin slices that capacity rating becomes 99.7cpm under a branch of situation.Under 100 thin slices became a branch of situation, capacity rating received the influence that stops of image forming apparatus hardly, and under two thin slices became a branch of situation, capacity rating reduced greatly.
Therefore; For example; United States Patent(USP) No. 5020785 proposes following structure: when the thin slice bundle by when the next gutter pos of attachment means moves; The thin slice bundle relatively moved with the mobile edge of the attachment means direction opposite with the attachment means moving direction, shortened the time that the thin slice bundle moves to next gutter pos thus.
Yet the weight of thin slice bundle depends on thin slice quantity and the thin slice kind that will bind.That is to say that the weight of thin slice bundle is along with the increase of whenever intrafascicular thin slice quantity perhaps increases along with the increase of size or grammes per square metre (grammage).At the electrical motor that is used for moving the thin slice bundle, rotating speed is slack-off along with the increase of thin slice Shu Chongliang.Therefore, when moving the thin slice bundle when not considering thin slice quantity that thin slice is intrafascicular or thin slice kind and with constant speed, need electrical motor to have big output, this causes the maximization of device or the increase of cost.
Summary of the invention
The present invention provides a kind of sheet handling device, in this device, when the multi-section position of thin slice bundle is bound, is not improving capacity rating under aggrandizement apparatus or the increase condition of cost, and the image forming apparatus that is provided with this sheet handling device is provided.
According to a first aspect of the invention, a kind of sheet handling device, it comprises: sheet stacking portion, in this sheet stacking portion, pile up the thin slice bundle; Stapling unit, it is to being stacked on the thin slice Shu Jinhang bookbinding in the sheet stacking portion; And thin slice bundle mobile member; It moves the thin slice bundle; Wherein, when a plurality of gutter pos of the thin slice bundle that in sheet stacking portion, piles up are bound processing, along with the minimizing of the intrafascicular thin slice quantity of the thin slice that moves by thin slice bundle mobile member; Perhaps along with the decline of the weight of the thin slice bundle that moves by thin slice bundle mobile member, be set at the moving velocity of thin slice bundle faster.
In addition, the present invention provides a kind of sheet handling device, and it comprises: sheet stacking portion, in this sheet stacking portion, pile up the thin slice bundle; Thin slice bundle mobile member, it moves the said thin slice bundle that is stacked in the said sheet stacking portion, attachment means, it binds processing at a plurality of gutter pos that are stacked on the said thin slice bundle in the said sheet stacking portion; The attachment means mobile device, it moves said attachment means; And control part; It controls said thin slice bundle mobile member and said attachment means mobile device; A plurality of gutter pos with at said thin slice bundle are bound processing; Wherein, Said control part is controlled said thin slice bundle mobile member and said attachment means mobile device; When making quantity when the intrafascicular thin slice of the said thin slice that moves by said thin slice bundle mobile member less than the present count value perhaps when the weight of the said thin slice bundle that moves by said thin slice bundle mobile member during less than the preset weight value; Carry out moving between the said gutter pos through moving of said attachment means and said thin slice Shu Erzhe, when the quantity of the intrafascicular thin slice of the said thin slice that is moved by said thin slice bundle mobile member is not less than said present count value or when the weight of the said thin slice bundle that is moved by said thin slice bundle mobile member is not less than said preset weight value, only carry out mobile between the said gutter pos through said attachment means.
According to a second aspect of the invention, a kind of image forming apparatus is included in the image forming part that forms image on the thin slice; And according to the sheet handling device of the first aspect of the present invention that the thin slice that is formed with image is handled.
Therefore, when the multi-section position of thin slice bundle is bound, through relatively moving of moving of attachment means and thin slice beam reversal attachment means is moved to next gutter pos, this makes and shortens bookbinding processing time.The moving velocity of thin slice bundle changes according to the intrafascicular thin slice quantity of thin slice or the weight of thin slice bundle, makes under the situation of the smallest number thin slice in short processing time of needs, can shorten the bookbinding processing time.
With reference to the explanation of accompanying drawing to exemplary embodiment, further characteristic of the present invention will become obvious from following.

2The time, set attachment means 101 and reverse each other first Move Mode that moves of the thin slice bundle on the process disk 130.Under first Move Mode, whether in step S102, make flake weight less than 100g/m
2Judgement.When flake weight in step S102 is not less than 100g/m
2The time, the thin slice bundle moving velocity setting process B that carries out the setting of the moving velocity of thin slice bundle when attachment means 101 is shifted to next gutter pos at step S104.On the other hand, when flake weight in step S102 less than 100g/m
2The time, carry out thin slice bundle moving velocity setting process A.Therefore, flake weight is designated as grammes per square metre.Perhaps, can confirm flake weight by lamina dimensions.
The setting process A of the thin slice bundle moving velocity under the light situation of flake weight will be described with reference to Figure 12.
In step S201, do the judgement whether intrafascicular thin slice quantity of slice is not less than predetermined thin slice quantity X.When the intrafascicular thin slice quantity of thin slice in step S201 is not less than X, set only through moving second Move Mode that attachment means 101 moves gutter pos.
On the other hand, when the intrafascicular thin slice quantity of thin slice in step S201 during, do the judgement (step S202) whether the intrafascicular thin slice quantity of slice is not less than thin slice quantity Y less than X.When the intrafascicular thin slice quantity of thin slice in step S202 was not less than thin slice quantity Y, the moving velocity of the thin slice bundle when attachment means 101 is shifted to next gutter pos was set at B (step S204).On the other hand, when the intrafascicular thin slice quantity of thin slice in step S202 during less than Y, the moving velocity of the thin slice bundle when attachment means 101 is shifted to next gutter pos is made as the A faster than B (step S203).Then, in step S206, calculate thin slice bundle miles of relative movement M.Confirm thin slice bundle miles of relative movement M by following formula.Suppose that Lmm is the distance to next gutter pos, C is the moving velocity of attachment means.In the present embodiment, the moving velocity of attachment means keeps constant.
Moving velocity at the thin slice bundle is set under the situation of A,
M＝L/(A+C)×A
Moving velocity at the thin slice bundle is set under the situation of B,
M＝L/(B+C)×B
Set thin slice bundle miles of relative movement as described above, end of program.
Figure 13 diagram the thin slice bundle moving velocity setting process B under the heavy situation of flake weight.Shown in figure 13, the quantity of the thin slice of switching moving velocity changes according to the weight of thin slice.That is to say, consider the thin slice Shu Chongliang that confirms by flake weight * thin slice quantity, carry out switching controls.In step S301, when the intrafascicular thin slice quantity of thin slice is not less than thin slice quantity V (less than X), set only through moving second pattern that attachment means 101 moves gutter pos.
On the other hand, when the intrafascicular thin slice quantity of thin slice in step S301 during, need do the judgement (step S302) whether the intrafascicular thin slice quantity of slice is not less than thin slice quantity W less than thin slice quantity V.Thin slice quantity W is less than thin slice quantity V.When the intrafascicular thin slice quantity of thin slice in step S302 was not less than W, the moving velocity of the thin slice bundle when attachment means 101 is shifted to next gutter pos was set at B (step S 304).On the other hand, when the intrafascicular thin slice quantity of thin slice in step S302 during less than W, the moving velocity of the thin slice bundle when attachment means 101 is shifted to next gutter pos is made as the A faster than B (step S303).In step S306, be similar to setting process A, can calculate thin slice bundle miles of relative movement M.
Therefore, can whether be not less than predetermined thin slice quantity and judge whether thin slice Shu Chongliang is not less than predetermined value based on being stacked on the intrafascicular thin slice quantity of thin slice on the stack tray 200.The intrafascicular thin slice quantity of thin slice on being stacked on stack tray 200 is during less than predetermined thin slice quantity, and it is fast that the moving velocity of thin slice bundle is set at the moving velocity that moves the thin slice bundle when being not less than predetermined value than thin slice Shu Chongliang.When the moving velocity of thin slice bundle being set very fast, the miles of relative movement of thin slice bundle is elongated relatively.In the present embodiment, because the moving velocity of attachment means keeps constant, so shorten the bookbinding processing time through increasing the thin slice bundle mobility of gutter pos in moving.
[gutter pos move operation]
Then, with the bookbinding processing operation of explaining that thin slice bundle and attachment means relatively move.At thin slice bundle moving velocity is that 200mm/s, thin slice bundle miles of relative movement are that 48mm, attachment means moving velocity are that 300mm/s and bookbinding spacing are under the condition of 120mm, carries out two position bookbindings.
At first, little offset stacked will be described, wherein, thin slice always is discharged to the same position of stack tray.
Figure 14 A diagram just in time be stacked on the process disk 130 with the state between first position is bound at the thin slice bundle.The thin slice middle position of Reference numeral 801 expressions when thin slice is discharged to stack tray, Reference numeral 800 expression thin slice central authorities.
Shown in Figure 14 A, in the position that is discharged to stack tray with respect to the thin slice bundle to the aligned in position thin slice bundle of right avertence thin slice bundle miles of relative movement.Then, bind, make the attachment means 72mm that moves to right, thin slice Shu Zuoyi 48mm, thus make attachment means move to next gutter pos.
Figure 14 B diagram attachment means moves to the state of second gutter pos.Reference numeral 802 expression binding needles.Shown in Figure 14 B, when the thin slice bundle was discharged to stack tray, thin slice middle position 801 was overlapped with thin slice central authorities 800.Therefore, consider moving of thin slice bundle, in out-of-position aligned in position in advance, this allows thin slice bundle to discharge any position on stack tray with the thin slice bundle.
Figure 14 C diagram the state before first position of next thin slice bundle is being bound just in time.Shown in Figure 14 C, in the position that is discharged to stack tray with respect to the thin slice bundle to the aligned in position thin slice bundle of left avertence thin slice bundle miles of relative movement.The attachment means position of readiness also is located at the right side.For first position, attachment means position of readiness and thin slice bundle aligned position exchange to be set.Then, bind, make the attachment means 72mm that moves to left, the thin slice bundle 48mm that moves to right, thus make attachment means move to next gutter pos.
Figure 14 D diagram attachment means moves to the state of second gutter pos of this next thin slice bundle.Reference numeral 802 expression binding needles.Shown in Figure 14 D, when the thin slice bundle was discharged to stack tray, thin slice middle position 801 was overlapped with thin slice central authorities 800.Therefore, consider moving of thin slice bundle, in out-of-position aligned in position in advance, this allows thin slice bundle to discharge any position on stack tray with the thin slice bundle.Then, attachment means moves to position shown in Figure 14 A once more.Repeat this operation, the thin slice bundle can be discharged any position on stack tray.
Under the situation of second Move Mode (the thin slice bundle is Move Mode not) that only moves staple position through mobile attachment means, be discharged to the aligned in position thin slice bundle on the stack tray at the thin slice bundle, attachment means 101 is in the first gutter pos standby.Then, first gutter pos is bound, after bookbinding finished, only attachment means 101 moved, and attachment means 101 stops at second gutter pos.
[stapling mode operation]
The operation of two positions bookbinding is described with reference to the stapling mode treatment scheme of Figure 15.Carry out the stapling mode treatment scheme after pressing initiating key 314.Each thin slice is carried out the stapling mode treatment scheme.
In step S401, make the judgement of whether connecting (turn on) thin slice detecting sensor 31.The processing that repeats among the step S401 is connected up to sensor 31.When thin slice detecting sensor in step S401 31 was connected, thin slice was discharged to process disk 130 (step S402), thin slice by alignment member 141 with 142 at preposition align (step S403).Make in step S404 whether the thin slice that is alignd is the judgement (step S404) of last thin slice of this thin slice bundle.When thin slice was not last thin slice in step S404, the stapling mode treatment scheme finished.On the other hand, when thin slice in step S404 is last thin slice, to this thin slice Shu Jinhang bookbinding (step S405).Then, move the definite method of establishing method through gutter pos attachment means is moved to next gutter pos (step S406).Second gutter pos is bound (step S407), and the thin slice bundle is discharged to stack tray 200 (step S408), and the stapling mode treatment scheme finishes.
