In addition, in the present embodiment, between a pair of support frame 18 of index position, set up additional fan assembly 40 ', and this index position makes rising to become horizontal direction at row's paper conveyer belt 15 change of directions of the upstream side of framework 30.Arrive the direction of the sheet-fed P of index position by this additional fan assembly 40 ' conversion, and can prevent the unstable or vibration of delivery status.By from the upper surface blown air-flow of this additional fan assembly 40 ' to the sheet-fed P that is in index position, this sheet-fed P is the state that is urged downwardly, and can suppress vibration etc. thus, makes delivery status keep stable.
Fig. 8 is the instruction diagram of observing the sheet-fed descending from the downstream of paper feeding direction of explanation effect of the present invention, (A) expression from the fan component 40 that is provided with inclination attitude obliquely to the state of sheet-fed blowing gas stream, (B) as a comparative example, expression from the fan component that is provided with flat-hand position towards the state of vertical direction to the sheet-fed blowing gas stream.
At first, (A) with reference to Fig. 8 describes the situation that fan component 40 is set with inclination attitude.When fan component 40 being set with inclination attitude, be made as under the situation of α at the angle of inclination of the relative horizontal surface of sheet-fed P that will be V word shape, set (the β＞α) of inclination angle beta with respect to the horizontal plane of fan component 40 than above-mentioned α the earth.By carrying out the in-place test of test of many times in advance, and know the tilt angle alpha of sheet-fed P in advance according to its test results from the various characteristics of the sheet-fed P side of the various characteristics of the device sides such as output of the flow of the air-flow of valve pipe arrangement 50 and fan component 40 and papery etc.
Below, under the state of the inclination angle beta of having set fan component 40, to be positioned at air flow jetting structure 20 under sheet-fed P when spraying air-flow from valve pipe arrangement 50 and each fan component 40,1 X with the right side of sheet-fed P is an example, if to the air-flow of this X injection from fan component 40, then from the air-flow of fan component 40 to an X, vertical line L in relative Fig. 8 (A), with and by the state of angulation " β-α " between the vertical line L of some X, from the left side towards an X obliquely to the extroversion effect.
Therefore, tilt to blow to the air-flow of an X from the inboard,,, make sheet-fed P outwardly so be subjected to the guiding of this air-flow owing to the upper surface along sheet-fed P over half outwards passes.Because the effect of this air-flow and also identical with a position of X symmetry on sheet-fed P, just direction is opposite, the result, sheet-fed P is the boundary with the central portion of Width, the state that formation tilts and stretches upward by this strenuous status, can make sheet-fed P keep V word shape ground and descend.
Such sheet-fed P, because under the state of well maintained V word shape, be subjected to pushing from the air-flow of valve pipe arrangement 50 and fan component 40, descend rapidly with the speed faster than natural falling speed, even under the not only thin but also soft situation of sheet-fed P, with respect to the sheet-fed P that had before fallen, also can be with the overlapping successively folding and unfolding of the neat state of limit portion sign indicating number.Therefore, suitably sign indicating number is neat really in its end of row's paper buttress P2 that obtains.
On the contrary, shown in Fig. 8 (B), when being flat-hand position setting fan component 40, sheet-fed P is formed under the set condition of V word shape, from the right side that blows to sheet-fed P respectively of fan component 40 and the some X in left side, the air-flow of Y, owing to act on from the outside with respect to vertical line L, L, so air-flow over half is towards the inboard of sheet-fed P by an X, Y.
Therefore, because sheet-fed P is subjected to guide towards its inboard air-flow, mutual approaching state so conformality is poor, can not be kept V word shape originally well about easy deformation became, and sheet-fed P is descended with unsure state.In addition, in the way that descends, because of producing attitude change around vertical direction rotation etc., owing to pile up so that unjustified state is overlapping successively with respect to the sheet-fed P that had before fallen, so, the state that huddles that the row's paper buttress P2 that obtains does not collect for its end.
In addition, be ground paper and do not allow under the situation of yielding cardboard,,, sheet-fed P is descended with the state of keeping V word shape because sheet-fed P is indeformable even set in flat-hand position under the state shown in (B) of Fig. 8 of fan component 40 at sheet-fed P.
Air flow jetting structure 20 of the present invention as mentioned above, is used for by the upper surface jet-stream wind to the sheet-fed P that discharges successively from printing device 12, and the descending speed ground that increases this sheet-fed row's of formation paper buttress P2 overlappingly successively.By substantial middle portion towards the Width of sheet-fed P, and approximate vertical is sprayed said flow on the whole length of paper feeding direction, simultaneously, with above-mentioned substantial middle portion is the boundary, towards about the sheet-fed P towards outside and spray said flow obliquely to separated direction, so constitute air flow jetting structure 20.
If more specifically represent this formation, then air flow jetting structure 20 is by applying the jet power of air-flow to the sheet-fed P that discharges successively from printing device 12, and this sheet-fed P is descended, and the row's of formation paper buttress P2 constitutes overlappingly successively.Air flow jetting structure 20 has: valve pipe arrangement (central portion air flow jetting mechanism) 50, it is along the central portion of the Width of sheet-fed P, on the whole length of paper feeding direction to this central portion jet-stream wind; Fan component 40 (sidepiece air flow jetting mechanism) is separately positioned on the position, the left and right sides of this valve pipe arrangement 50, to the both sides of sheet-fed P jet-stream wind.Above-mentioned valve pipe arrangement 50 can be defined as, and is by the air flow jetting direction can be constituted obliquely towards the isolated direction of vertical surface along the jet-stream wind of above-mentioned valve pipe arrangement 50.
If adopt the air flow jetting structure 20 that so constitutes,, by being injected in the thrust pressure from the air-flow of valve pipe arrangement 50 and fan component 40 of its upper surface, and can the speed faster descend than natural falling speed for sheet-fed P.In addition, the sheet-fed P in the decline by towards the substantial middle portion of Width and approximate vertical is sprayed on the whole length of paper feeding direction from valve pipe arrangement 50 windstreams (air-flow), forms the V word shape that central portion expands towards the below.In addition, with substantial middle portion be the boundary sheet-fed P about face, since from fan component 40 obliquely outwardly and towards separated direction jet-stream wind, so the state that face deviates from mutually towards about the central portion the direction of becoming sheet-fed P stretches can stable maintenance V word shape by forming strenuous status thus.Therefore, by more in the past than the emitted dose that integrally increased the air-flow of sheet-fed P, and can velocity ratio high in the past and stable status under, keep V word shape ground and fall sheet-fed P smoothly.
In addition, fan component 40, because the spray angle with respect to sheet-fed P of this air-flow of scalable, so can be by the simple operations of multiple this spray angle of variation, the decline state of one side above-mentioned angle of Visual Confirmation and sheet-fed, find out the best angle that sheet-fed P reaches V word shape on one side easily, compare, improved the operability of draught regulation operation with the mode of only regulating the air flow rate that is difficult to Visual Confirmation in the past.
And, in fan component 40, because a plurality of units fan 44 is installed, so by operation fan component 40, can set the angle of all unit fans 44 simultaneously, compare with the situation that must operate constituent parts fan 44 respectively one by one thus, can improve operability in each stage, simultaneously, also can eliminate when difference operating unit fan 44, produce scattered here and there bad phenomenon because of the angle of setting is irregular.
In addition, especially adopt fan component 40, as to the central portion of sheet-fed P along paper feeding direction extend the ground wire spray from valve pipe arrangement 50 windstream and clip the air-flow device of position, the left and right sides jet airstream of this air flow sheet-fed P.And, since from the air-flow of fan component 40 to sheet-fed P about face do not produce local power, and integral body is sprayed equably, for example, even sheet-fed P is a thin paper, do not produce yet sheet-fed P about face because of the power of air-flow form wave inception state, upset the decline state of sheet-fed P, and bad phenomenon such as sign indicating number paper variation generally can the good row's paper buttress P2 of accomplished sign indicating number paper.
The present invention is not limited to the above embodiments, also comprises following content.
(1) in the above-described embodiment, as the parts that are used for sheet-fed P inclination jet-stream wind, the fan component 40 that a plurality of units fan 44 constitutes is equipped with in employing, but the parts that the present invention is not limited to sheet-fed P inclination jet-stream wind are fan component 40, also can only adopt auxiliary valve pipe arrangement 50 ' shown in Figure 5, replace the fan component 40 that adopts.
(2) in the above-described embodiment, same settings is arranged on the air-supply power of all unit fans 44 on each fan component 40, but the present invention is not limited to the air-supply power of whole same settings units fan 44, also can form the formation that can change the air-supply power of unit fan 44 at least by each fan component 40.By regulating the electric current of supplying with unit fan 44, can realize the adjusting of this air-supply power easily.Like this, if air output that can the unit's of adjusting fan 44 just can utilize the angular adjustment of fan component 40 and the summation action that air output is regulated, sheet-fed P is descended with stable status more.
