摘要:
A sheet transport path extending from a carry-in entrance to a carrying-out exit is made small and compact in an apparatus configuration provided with a path without performing the folding processing and another path to perform the folding processing in between the carry-in entrance and the carrying-out exit. The configuration is provided with a first transport path 32 for guiding a sheet from the carry-in entrance 30 to the carrying-out exit 31 without performing the folding processing, a second transport path 33 for performing the folding processing on a sheet from the carry-in entrance, and folding processing means 48 disposed in the path 33 to fold the sheet. Then, the second transport path 33 is disposed to cross the first transport path 32, and a path end portion (first switchback path 34) of the second transport path 33 for guiding the sheet to a folding position Np1 and another path end portion (second switchback path 35) for guiding the folded sheet to the downstream side from the folding position are disposed inside areas opposite each other below and under or to the left and right of the first transport path 32. In other words, when the first transport path 32 is formed of a linear path in the horizontal direction, the path 34 is disposed above the path 32, and the path 35 is disposed below the path 32.

To provide a folding mechanism for folding a sheet with a simplified structure having no fear of causing a deviation from the fold position, wrinkle and the like, provided are a transport path 33 for transporting a sheet, and folding processing means 48 disposed in the transport path to fold the sheet. Then, the folding processing means is comprised of folding roll pairs (41b, 49, 50) coming into press-contact with one another to rotate in the opposite directions, and folding deflecting members (53, 54) for guiding the fold of the sheet to the nip portions (Np1, Np2) of the folding roll pairs. Then, the folding deflecting members are provided with driven rollers (53a, 54a) in contact press-contact with the roll periphery of one of the folding roll pair, and curved guides (53a, 54a) along the roll periphery of the other one. The driven roller provides the sheet with transport force to guide to the nip portion, and the curved guide brings the sheet along the roll periphery of the other one to guide to the nip portion.

In a sheet folding apparatus, to enable a jammed sheet to be removed with ease when a jam occurs, a casing having a carry-in entrance and a carrying-out exit is divided into an upper unit and a lower unit via a first transport path for carrying a sheet from the carry-in entrance to the carrying-out exit, a second transport path for performing folding processing on a sheet is disposed in the direction for crossing the first transport path, and in the upper unit are disposed a sheet front end switchback path for reversing and carrying the sheet toward a folding roller pair and sheet deflecting means for guiding the sheet to the folding roller pair. Then, the upper unit is coupled to the lower unit to be openable and closable by a hinge shaft rotating around one side end portion orthogonal to the sheet transport direction of the first transport path.

The invention enables skew of a sheet to be reliably corrected with a simplified structure in feeding the sheet to a processing position of sheet folding or the like using a roller pair. Provided are a transport roller pair (41a, 41b) in press-contact with each other, gate stopper means (43) disposed on the upstream side of a press-contact portion (p1) of the transport roller pair to strike and regulate a front end of a sheet, register area (Ar) disposed on the upstream side of the gate stopper means to curve and deform the sheet with the front end regulated, and stopper driving means (44) for shifting the gate stopper means to positions between an operating position of a sheet transport path and a retracted position outside the transport path. Then, the gate stopper means is formed so that the shift trajectory of a regulation surface (43s) shifting from the operating position (Ps) for striking and regulating the front end of the sheet to the retracted position (Pw) is to guide the front end of the sheet to the press-contact portion (p1) of the transport roller pair.

To enable a sheet to be folded in an accurate position with a simplified folding mechanism in performing folding processing on the sheet with a pair of folding rollers, a second transport path is disposed in a direction for crossing a first transport path for guiding a sheet from a carry-in portion to a carrying-out portion, and in the cross portion are disposed a folding roller pair for performing folding processing on a sheet, and a folding deflecting member for inserting a fold of the sheet in the nip portion. Then, the folding deflecting member is comprised of a driven roller that comes into press-contact with a roller periphery of the folding roller pair, and a shift member for shifting the driven roller from a waiting position to an actuation position, and by the operation of shifting the driven roller from the waiting position outside the path to the actuation position, the sheet front end portion is fed to the nip portion from an upstream-side guide path formed in the second transport path. At this point, the shift velocity of the driven roller is made higher than the velocity of the sheet sent from the first transport path.

摘要:
A sheet folding apparatus for folding a sheet, includes a first transport path for guiding the sheet from a carry-in portion to a carrying-out portion without folding; a second transport path branching off from the first transport path for folding the sheet; folding rollers to fold the sheet; a driving motor; and a control device for controlling the driving motor. The folding rollers are disposed in between the carry-in roller and the carrying-out roller. The first transport path has a pinch roller and a guide cover for covering the folding. The guide cover shifts between an actuation position in which the sheet does not contact the folding rollers and a non-actuation position in which the sheet engages with the folding rollers. The control device controls the guide cover to shift to the actuation position with the pinch roller separated from a periphery of the one of the rollers.
