Fig. 2 represents the synoptic map of folding handling part 50.Folding handling part 50 has the first block 51C, paper folding board (paper foldling mechanism) 52, first roller 53, second roller 54, the 3rd roller 55, transport path switching part 57, directing plate 58, second block 581 and paper pressing mechanism 59, carries out the eighty percent discount or three foldings of paper and handles.In addition, in this embodiment, it is right that first roller 53 and second roller 54 constitute first folding roller, and it is right that second roller 54 and the 3rd roller 55 constitute second folding roller.That is, first folding roller to second folding roller to shared second roller 54.So just can reduce the part number, the miniaturization and of implement device.Certainly, also can constitute first folding roller to right by different rollers respectively with second folding roller.
Transport path H1 is made of directing plate 51A and directing plate 51B, is provided with the first block 51C of the position of restriction paper S in the sheet transport direction downstream of transport path H1.According to the formation position of the antiquarian and first folding line, move to sheet transport direction and opposite sense the sheet transport direction front end butt of the first block 51C and paper S and the first folding line position of stipulating paper S.
Across the relative position of roll gap portion between transport path H1 and first roller 53 and second roller 54, be provided with relative transport path H1 paper folding board 52 free to advance or retreat.Paper folding board 52 is usually located at the position of avoiding transport path H1, can not hinder from transport path H1 and carry moving of the paper S come.When the assigned position that is limited the paper S of position by the first block 51C formed first folding line, paper folding board 52 was outstanding by the direction of the roll gap portion of not shown drive source between first roller 53 and second roller 54.Like this, the assigned position of paper S is directed into the roll gap portion between first roller 53 and second roller 54, and forms first folding line on paper S.
Carry out crimping by not shown force application mechanism to constituting the first right roller 53 of first folding roller and second roller 54, at least one roller drives along the direction of arrow rotation of figure.The outer peripheral face of first roller 53 and second roller 54 has high friction drag respectively.
The transport path switching part 57 that setting can be swung by screw actuator SD.When paper S being carried out three folding processing, transport path switching part 57 is positioned at the position shown in the solid line, and paper S is directed to the transport path H10 that is formed by directing plate 58.On the other hand, paper S is being carried out eighty percent discount, that is, when doubling and middle bookbinding, doubling processing, transport path switching part 57 is directed to paper S transport path H11 and is transported to discharge orifice E1 along the swing of the anticlockwise direction among the figure.
Transport path H10 forms with respect to intersecting with the centre of gration that is connected first roller 53 straight line vertical with the straight line of the centre of gration of second roller 54.So just form kink being transported on the paper S of transport path H10.And, in transport path H10, be provided with second block 581.This second block 581 props up first folding line of paper S and form kink in paper S, moves to sheet transport direction and opposite sense according to the formation position of second folding line.
Make right second roller 54 and the 55 mutual crimping of the 3rd roller of formation second folding roller by not shown force application mechanism, at least one roller drives along the rotation of the direction of arrow among the figure.Here, as described later, from be easy to form the angle of kink among paper S, the surface friction drag of preferred the 3rd roller 55 is littler than the surface friction drag of second roller 54.
Fig. 3 represents near the enlarged drawing the 3rd roller 55.In addition, for easy to understand, omitted paper pressing mechanism 59 described later in the figure.As shown in the drawing, in paper folding apparatus of the present invention, the hand of rotation upstream side of roll gap portion that is covered the 3rd roller by cap assembly 56 is until the part of adjacent nip portion.Like this, as shown in Figure 4, the second folding line predetermined portions of paper S will be postponed and be entered the right roll gap portion of second folding roller, forms the second kink SB in paper effectively, is positioned at the opening of paper of front by the second kink rejection ratio, first folding line.Here, be the center with the axle of the 3rd roller 55, the front end 563 of preferred cap assembly 56 and the angulation θ of roll gap portion are in 25 °～35 ° scope.In addition, at the end of angle θ, that is, roll gap portion is when Width is long, with the Width central portion of the roll gap portion cardinal extremity as angle θ.If 25 ° of described angle θ less thaies, then the second folding line predetermined portions of paper S may not can successfully to enter second folding roller right, can not form second folding line at assigned position.On the other hand,, may on paper S, just the second kink SB can be do not formed fully, the opening of paper of front can not be positioned at by the second kink SB rejection ratio, first folding line if described angle θ surpasses 35 °.
In Fig. 3, the base portion 561 of cap assembly 56 and anterior 562 is " ヘ " word shape ground and engages.And the friction drag of front portion 562 that contact with paper S, cap assembly 56 is bigger than the surface friction drag of the 3rd roller 55.The second folding line predetermined portions that so just can postpone paper S effectively enters the right roll gap portion of second folding roller, forms the second kink SB on paper S effectively.Material as anterior 562 for example, can be resin films such as polyethylene terephthalate (PET) film.Base portion 561 and anterior 562 both can split manufacturing and joint, also can be integrally formed.
On the other hand, though the shape of the 3rd roller 55 is not particularly limited,, large-diameter portion 551 preferred shown in Figure 5 and minor diameter part 552 are in the shape that axially alternately comes and goes.So just can further reduce the surface friction drag of the 3rd roller 55, the second folding line predetermined portions that can postpone paper S more effectively enters the right roll gap portion of second folding roller.
The sheet transport direction downstream of the roll gap portion between first roller 53 and second roller 54, the sheet transport direction upstream side of the roll gap portion between second roller 54 and the 3rd roller 55 is provided with paper pressing mechanism 59.Fig. 6 represents near the enlarged drawing the paper pressing component 59.Paper pressing mechanism 59 has as the bar-like member 592 in the barrel-contoured chip part 591 of support unit and the barrel-contoured chip part 591 of insertion.The top of chip part 591 is installed on the matrix 593.And the girth of bar-like member 592 is than all length of chip part 591, and bar-like member 592 maintains the mode of general horizontal direction and suspended in midair by chip part 591 with length direction.Like this, bar-like member 592 and chip part 591 with and matrix 593 between installation portion be fulcrum 594 and freely the swing.In addition, paper pressing mechanism 59 can be the parts that axial length is long, also can axially be provided with a plurality of.And, preferred bonding bar-like member 592 and chip part 591.
