Sheet folding device

Abstract

Provided is a sheet folding device which can reduce the pellet exchange frequency and an operation stop time accompanying a pallet exchange. The sheet folding device includes: (a) first movement unit disposed to be able to be raised/lowered above a placement region; (b) a second movement unit which is supported by the first movement unit and reciprocates along the placement region in a first direction; and (c) a sheet discharge device which is supported by the second movement unit and has a sheet discharge port facing the placement region, the sheet discharge port reciprocating along the placement region in a second direction crossing the first direction. Sheets continuous in the longitudinal direction are discharged from the sheet discharge port of the sheet discharge device so that the width direction of the sheets crosses the second direction.

1 . A sheet folding device comprising:
 a first movement unit disposed to be able to be raised/lowered above a placement region;   a second movement unit supported by the first movement unit and reciprocating along the placement region in a first direction; and   a sheet discharge device supported by the second movement unit and having a sheet discharge port facing the placement region, the sheet discharge port reciprocating along the placement region in a second direction crossing the first direction,   wherein a sheet continuous in a longitudinal direction is discharged from the sheet discharge port of the sheet discharge device so that a width direction of the sheet crosses the second direction.   
     
     
         2 . The sheet folding device according to  claim 1 , wherein the second movement unit stops at a plurality of positions at a distance of not less than a width dimension of the sheet in the first direction, and
 the sheet discharge port of the sheet discharge device reciprocates along the placement region in the second direction orthogonal to the first direction and the sheet is discharged from the sheet discharge port so that the width direction of the sheet coincides with the first direction.   
     
     
         3 . The sheet folding device according to  claim 1 , further comprising a pressing member that returnably moves toward the placement region, on each side of the sheet discharge device in the first direction. 
     
     
         4 . The sheet folding device according to  claim 2 , further comprising a pressing member that returnably moves toward the placement region, on each side of the sheet discharge device in the first direction. 
     
     
         5 . The sheet folding device according to  claim 1 , further comprising:
 a track shifter disposed above the second movement unit, supported to be swingable by the first movement unit and having a reception roll that receives the sheet and a discharge roll that discharges the received sheet, the discharge roll reciprocating in the first direction in conjunction with the reciprocation of the second movement unit in the first direction;   a plurality of first rolls supported by the first movement unit and defining a first conveyance path where the sheet is conveyed to the reception roll of the track shifter; and   a plurality of second rolls supported by the second movement unit and defining a second conveyance path where the sheet is conveyed from the discharge roll of the track shifter to the sheet discharge device.   
     
     
         6 . The sheet folding device according to  claim 5 , wherein the second movement unit stops at a plurality of positions at a distance of not less than a width dimension of the sheet in the first direction, and
 the sheet discharge port of the sheet discharge device reciprocates along the placement region in the second direction orthogonal to the first direction and the sheet is discharged from the sheet discharge port so that the width direction of the sheet coincides with the first direction.   
     
     
         7 . The sheet folding device according to  claim 5 , further comprising a pressing member that returnably moves toward the placement region, on each side of the sheet discharge device in the first direction.
