[setting for the method for attachment means mobile between gutter pos]
Below, by explanation when binding for 2, attachment means 101 moves to the operation of next gutter pos from the first gutter pos.
When carrying out binding process at least two positions of sheet bundle, sheet handling device in the present embodiment has the first Move Mode, in this mode, the sheet bundle oppositely movement mutually in attachment means 101 and process disk 130, thus attachment means 101 is moved to next gutter pos.In addition, the sheet handling device of the present embodiment has the second Move Mode, in this mode, only moves attachment means 101 and does not move sheet bundle.Attachment means 101 is moved by attachment means mobile device, moves sheet bundle by the mobile alignment member 141 and 142 forming sheet bundle mobile member.
Figure 11 illustrates gutter pos moving method setting process.Just start key 314 with before starting to duplicate pressing, carry out gutter pos moving method setting process.In step S101, make and whether be less than 200g/m from the flake weight (grammes per square metre) of operating portion input
2judgement.When in step S101, flake weight is not less than 200g/m
2time, set by means of only mobile attachment means 101 to move second Move Mode (sheet bundle is Move Mode not) of gutter pos.When sheet bundle has very heavy weight, because the total weight of sheet bundle increases along with the increase of number of sheets forming sheet bundle, be necessary the electrical motor increasing the sheet bundle mobile member for driving mobile sheet bundle according to the weight increased.Owing to seldom using the sheet bundle with very heavy weight, thus in order to suppress the increase of electrical motor, relative movement is not carried out to the sheet bundle with very heavy weight.
On the other hand, when the flake weight in step S101 is less than 200g/m
2time, the first Move Mode of the sheet bundle oppositely movement mutually in setting attachment means 101 and process disk 130.Under the first Move Mode, make flake weight in step s 102 and whether be less than 100g/m
2judgement.When flake weight is not less than 100g/m in step s 102
2time, the sheet bundle moving velocity setting process B of the setting of the moving velocity of the sheet bundle when attachment means 101 being shifted to next gutter pos is carried out in step S104.On the other hand, when flake weight is in step s 102 less than 100g/m
2time, carry out sheet bundle moving velocity setting process A.Therefore, flake weight is designated as grammes per square metre.Or, can by lamina dimensions determination flake weight.
The setting process A of sheet bundle moving velocity when illustrating that flake weight is light with reference to Figure 12.
In step s 201, whether the number of sheets of making in sheet bundle is not less than the judgement of predetermined number of sheets X.When the number of sheets in sheet bundle is in step s 201 not less than X, set by means of only mobile attachment means 101 to move the second Move Mode of gutter pos.
On the other hand, when the number of sheets in sheet bundle is in step s 201 less than X, whether the number of sheets of making in sheet bundle is not less than the judgement (step S202) of number of sheets Y.When the number of sheets in sheet bundle in step S202 is not less than number of sheets Y, the moving velocity of sheet bundle when attachment means 101 being shifted to next gutter pos is set as B (step S204).On the other hand, when the number of sheets in sheet bundle in step S202 is less than Y, the moving velocity of sheet bundle when attachment means 101 being shifted to next gutter pos is set to the A (step S203) faster than B.Then, in step S206, sheet bundle miles of relative movement M is calculated.By the sheet bundle of formula determination below miles of relative movement M.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.
When the moving velocity of sheet bundle is set as A,
M＝L/(A+C)×A
When the moving velocity of sheet bundle is set as B,
M＝L/(B+C)×B
Set sheet bundle miles of relative movement as described above, end of program.
Figure 13 illustrates the sheet bundle moving velocity setting process B when flake weight is heavy.As shown in figure 13, the quantity switching the thin slice of moving velocity changes according to the weight of thin slice.That is, consider the sheet bundle weight determined by flake weight × number of sheets, carry out switching controls.In step S301, when the number of sheets in sheet bundle is not less than number of sheets V (being less than X), set by means of only mobile attachment means 101 to move the second pattern of gutter pos.
On the other hand, when the number of sheets in sheet bundle in step S301 is less than number of sheets V, the number of sheets of making in sheet bundle is needed whether to be not less than the judgement (step S302) of number of sheets W.Number of sheets W is less than number of sheets V.When the number of sheets in sheet bundle is in step s 302 not less than W, the moving velocity of sheet bundle when attachment means 101 being shifted to next gutter pos is set as B (step S 304).On the other hand, when the number of sheets in sheet bundle is in step s 302 less than W, the moving velocity of sheet bundle when attachment means 101 being shifted to next gutter pos is set to the A (step S303) faster than B.In step S306, be similar to setting process A, sheet bundle miles of relative movement M can be calculated.
Therefore, whether can be not less than predetermined number of sheets based on the number of sheets in the sheet bundle be stacked on stack tray 200 and judge whether sheet bundle weight is not less than predetermined value.When being stacked on the number of sheets in the sheet bundle on stack tray 200 and being less than predetermined number of sheets, the moving velocity of sheet bundle is set as the moving velocity moving sheet bundle when being not less than predetermined value than sheet bundle weight is fast.When being set by the moving velocity of sheet bundle very fast, the miles of relative movement of sheet bundle is relatively elongated.In the present embodiment, because the moving velocity of attachment means keeps constant, so shorten the binding process time by the sheet bundle mobility during increase gutter pos moves.
[gutter pos move operation]
Then, the binding process operation of sheet bundle and attachment means relative movement will be described.Be 200mm/s at sheet bundle moving velocity, under sheet bundle miles of relative movement is 48mm, attachment means moving velocity is 300mm/s and bookbinding spacing is the condition of 120mm, carry out two positions bookbindings.
First, little offset stacked will be described, wherein, thin slice is always discharged to the same position of stack tray.
Figure 14 A illustrates and is just in time stacked in process disk 130 with the state between binding the first position in sheet bundle.Reference numeral 801 represents the thin slice middle position when thin slice is discharged to stack tray, and Reference numeral 800 represents thin slice central authorities.
As shown in Figure 14 A, the aligned in position sheet bundle of position to right avertence sheet bundle miles of relative movement of stack tray is being discharged to relative to sheet bundle.Then, bind, attachment means is moved to right 72mm, sheet bundle moves to left 48mm, thus makes attachment means move to next gutter pos.
Figure 14 B diagram attachment means moves to the state of the second gutter pos.Reference numeral 802 represents binding needle.As shown in Figure 14B, when sheet bundle is discharged to stack tray, thin slice middle position 801 and thin slice central authorities 800 overlapped.Therefore, consider the movement of sheet bundle, by the aligned in position that sheet bundle is offseting in advance, this allows sheet bundle to discharge any position on stack tray.
Figure 14 C illustrates the state just in time before binding the first position of next sheet bundle.As shown in Figure 14 C, the aligned in position sheet bundle of position to left avertence sheet bundle miles of relative movement of stack tray is being discharged to relative to sheet bundle.Attachment means position of readiness is also located at right side.For the first position, attachment means position of readiness and sheet bundle aligned position exchange setting.Then, bind, attachment means is moved to left 72mm, sheet bundle moves to right 48mm, thus makes attachment means move to next gutter pos.
Figure 14 D diagram attachment means moves to the state of the second gutter pos of this next sheet bundle.Reference numeral 802 represents binding needle.As shown in fig. 14d, when sheet bundle is discharged to stack tray, thin slice middle position 801 and thin slice central authorities 800 overlapped.Therefore, consider the movement of sheet bundle, by the aligned in position that sheet bundle is offseting in advance, this allows sheet bundle to discharge any position on stack tray.Then, attachment means moves to position shown in Figure 14 A again.Repeat this operation, sheet bundle can discharge any position on stack tray.
When by means of only mobile attachment means the second Move Mode (sheet bundle is the Move Mode not) of mobile staple position, be discharged to the aligned in position sheet bundle on stack tray in sheet bundle, attachment means 101 is standby at the first gutter pos.Then, bind the first gutter pos, after bookbinding terminates, only attachment means 101 moves, and attachment means 101 stops at the second gutter pos.
[stapling mode operation]
Stapling mode treatment scheme with reference to Figure 15 illustrates the operation of two position bookbindings.Press after starting key 314 and perform stapling mode treatment scheme.Stapling mode treatment scheme is carried out to each thin slice.
The judgement of whether connecting (turn on) thin slice detecting sensor 31 is made in step S401.Repeat the process in step S401 until sensor 31 is connected.When in step S401, thin slice detecting sensor 31 is connected, thin slice is discharged to process disk 130 (step S402), and thin slice aligns (step S403) by alignment member 141 and 142 at preposition.Make the judgement (step S404) whether the thin slice that is aligned is last thin slice of this sheet bundle in step s 404.When thin slice is not last thin slice in step s 404, stapling mode treatment scheme terminates.On the other hand, when thin slice is last thin slice in step s 404, this sheet bundle is bound (step S405).Then, move by gutter pos the method that establishing method determines and attachment means is moved to next gutter pos (step S406).Bind (step S407) the second gutter pos, sheet bundle is discharged to stack tray 200 (step S408), and stapling mode treatment scheme terminates.
[experimental result]
The process of being moved by sheet bundle and attachment means moves the present embodiment of gutter pos is compared with the process of moving gutter pos by means of only attachment means, illustrative experiment result.
In figure 16, vertical axis represents capacity rating (number of sheets of per minute), and horizontal shaft represents the number of sheets in sheet bundle.Curve 850 represents when moving gutter pos by means of only attachment means relative to the change of the capacity rating of the number of sheets in sheet bundle.Curve 851 represent when moved by sheet bundle to move gutter pos with attachment means time relative to the change of the capacity rating of the number of sheets in sheet bundle.
