Deformed example 1

[0085] Figure 9 Shown is an enlarged configuration diagram of the superimposition processing unit A in Modification 1. FIG.

[0086] In Modification 1, based on the line segment T1 connecting the nip portion of the pair of diverting rollers 13 and the nip portion of the pair of registration rollers 15, the pair of diverting rollers 13 conveys the leading sheet toward the bending process. The path W2 side is a configuration in which the opposite side is conveyed.

[0087] With such a configuration, after the front end of the preceding sheet P1 collides with the registration roller pair 15, the preceding sheet P2 passes through the diverting conveying roller pair 13, and Figure 9 The direction of the arrow H1 of , that is, the line segment T1 connected to the nip portion of the registration roller pair 15 is used as a reference to send to the side opposite to the side of the bending processing conveyance path W2. Accordingly, between the pair of switch conveyance rollers 13 ...

Deformed example 2

[0089] Figure 10 Shown is an enlarged configuration diagram of a superimposition processing unit A in Modification 2. FIG.

[0090] The modified example 2 is as Figure 10 As shown, when viewed from the direction of the rotation axis of the rollers, the guide surface of the guide member 56 on the side of the bending process conveyance path W2 of the divert conveyance path W3 is connected to the nip part of the divert conveyance roller pair 13 and the registration roller pair 15. Line segment T1 of the clamping portion intersects. Specifically, the downstream side of the guide member 56 on the side of the bending process conveyance path W2 is located on the bend line T1 on the basis of the line segment T1 connecting the nip portion of the steering roller pair 13 and the nip portion of the registration roller pair 15 . Process the transport path W2 side.

[0091] With such a configuration, when the front end of the preceding sheet P1 collides with the registration roller pai...

Deformed example 23

[0093] Figure 11 Shown is an enlarged configuration diagram of the superimposition processing unit A in Modification 3. FIG.

[0094] In Modification 3, an elastic member for preventing the front end of the sheet from entering the flex space is provided in each flex space 51 , 52 .

[0095] When the sheet is curled to the side of the flex space, such as Figure 11 As indicated by the double-dashed arrow Z1 of , the front end of the sheet enters the deflection space, and the front end collides with the guide member forming the deflection space. When the front end collides with the guide member forming the deflection space, bending of the sheet may occur, and transportation failure may occur.

[0096] Therefore, in Modification 3, the elastic members 53 and 54 are respectively provided in the preceding sheet deflection space 51 and the subsequent sheet deflection space 52 . As these elastic members 53 , 54 , film members having a thickness of 0.1 to 0.2 [mm] are used, and wh...

Abstract

The present invention provides a sheet processing apparatus and an image forming system capable of suppressing conveyance failure of subsequent sheets. A sheet processing device such as the folding processing device 1 includes a conveying mechanism such as a registration roller pair 15 that conveys a sheet, and after a plurality of sheets are sequentially abutted against the conveying mechanism, the multiple sheets are overlapped by the conveying mechanism. Conveyance in which the preceding sheet P1 waiting for the arrival of the subsequent sheet P2 in a state of colliding with the conveying mechanism is deflected toward a side that does not prevent the following sheet P2 from entering the conveying mechanism.

Description

technical field [0001] The present invention relates to a sheet processing device and an image forming system. Background technique [0002] Conventionally, a well-known sheet processing device has a conveying mechanism for conveying sheets, and after a plurality of sheets are sequentially hit against the conveying mechanism, the conveying mechanism stacks and conveys the plurality of sheets. [0003] Patent Document 1 describes the following as the sheet processing apparatus described above. That is, the preceding sheet conveyed by the pair of skew correction rollers serving as the conveyance mechanism is conveyed substantially endlessly and then returned to the pair of skew correction rollers. After the front end of the preceding sheet collides with the skew correction roller pair and the skew is corrected, it waits for the arrival of the following sheet. In this standby state, the leading edge of the next sheet to be conveyed collides with the pair of skew correction ro...
