Since sheet producing device 101 is other than air-flow limiting unit 411 described below, with sheet producing device 100
(Fig. 1) is similarly constituted, and therefore, for common structure, is marked identical symbol and is omitted the description.
Air-flow limiting unit 411 shown in Figure 13 is configured in the top (upstream side) of the branch portion 54b of pipe 54.Air-flow limitation
Portion 411 has from the side wall side of supervisor 54a towards axis center and the air-flow limitation rotor plate 412 of the plate that is configured and makes gas
Ductility limit rotor plate 412 is into figure with the rotation section 413 of the arrow mark RD direction rotation indicated.In the example in figure 13, if
Rotor plate 412, which is limited, for a pair of of air-flow is singly configured in the side right direction R of supervisor 54a and the structure of the side left direction L.
Each air-flow limitation rotor plate 412 by rotation section 413 and is separately turned by the control of control device 110
It is dynamic.
The shunt position that the position of a pair of of air-flow limitation rotor plate 412 shunts delivery air M1 with branch portion 54b
On the basis of 54e, it is equivalent to the position of the side branched pipe 54c and the position of the side branched pipe 54d.
Air-flow limiting unit 411 replaces the air-flow limiting unit 401 (Fig. 5) being illustrated in the first embodiment and is set
It sets.That is, sheet producing device 101, which is used, replaces with air-flow limit for the air-flow limiting unit 401 of sheet producing device 100
The structure in portion 411 processed.
Air-flow limiting unit 411 has a pair of of air-flow limitation rotor plate 412 and moves a pair of of air-flow limitation rotor plate 412
Dynamic rotation section 413.
The position of air-flow limiting unit 411 is preferably, and near branch portion 54b, more preferably, passes through branch portion 54b
And state, the i.e. setting before branch is on supervisor 54a.In addition, air-flow limiting unit 411 is most preferably in supervisor 54a, away from
Branch portion 54b is closer.
Air-flow limitation rotor plate 412 is rotated by rotation section 413, and in the position for the section opening for crossing supervisor 54a
It sets and is displaced between the position along the axis direction of supervisor 54a.Air-flow limits rotor plate 412 to the section side of supervisor 54a
It is determined to the area of stretching by the amount of spin of rotation section 413.Therefore, by the movement of rotation section 413, and make supervisor 54a's
The sectional area that can be flowed through for delivery air M1 in inside changes.Rotation section 413 is equivalent to weight per unit area adjustment portion
341, and can be by control device 110 to the open and close of the movement of rotation section 413 and the amount of spin of rotation section 413

In branch 54b, compared with delivery air M2, a large amount of material flows in delivery air M3.Therefore, in roller portion 61, with
Right direction R is compared side, flows into a large amount of material from the side left direction L.
In contrast, the air-flow positioned at the side left direction L is made to limit center direction stretching of the rotor plate 412 to supervisor 54a
In the case where, the side left direction L is being leaned on compared with as the shunt position 54e in the center of supervisor 54a, the runner of delivery air M1 becomes
It is narrow.Therefore, in the inside of supervisor 54a, ventilation resistance is generated in the side left direction L.In this state, due to delivery air M1 and gas
Ductility limit rotor plate 412 collides, and flows in such a way that wraparound air-flow limits rotor plate 412, therefore, contained by delivery air M1
Material is biased to the side right direction R and is flowed.Since in the inside of supervisor 54a, material is biased to the side right direction R and is transferred, therefore, In
In branch portion 54b, compared with delivery air M3, a large amount of material flows in delivery air M2.Therefore, in roller portion 61,
Compared with the side left direction L, a large amount of material is flowed into from the side right direction R.
In addition, though air-flow limitation rotor plate 412 exerts one's influence to the flow velocity of delivery air M1, but to the shadow that air quantity applies
Sound be it is slight, the sum of air quantity of delivery air M2, M3 for flowing into roller portion 61 hardly happen variation.But it is generating
Delivery air M1 mixing air blower 56 wind-force it is weaker and be responsible for 54a sectional area in because air-flow limit rotor plate 412 due to
In the case where the large percentage of the area of reduction, it is possible to create the reduction of air quantity.
According to the sheet producing device 101 of second embodiment, by adjusting 157 pairs of gas of control unit by weight per unit area
Stream limiting unit 411 is controlled, so as to make the balance of left and right of the material flowed into roller portion 61 from pipe 54 change.
The effect controls air-flow limiting unit 401 with because adjusting control unit 157 by weight per unit area in the first embodiment
And the effect generated is identical.
Therefore, the sheet producing device 101 of second embodiment plays effect identical with sheet producing device 100.
