  In recent years, it has been demanded that the folding and unloading apparatus of the same folding apparatus can be adapted to both small and thin multi-page folding sheets.

  As shown in FIG. 3, the folding apparatus A1 of Patent Document 1 is a folding apparatus that uses the delivery fan E1, the conveyor G1, and the chopper folding mechanism F in the first conveyance path for conveying the folding book W1 that does not use the chopper folding mechanism F. The intervals between the delivery fan E and the conveyor G on the second conveyance path for conveying the book W cannot be adjusted. For this reason, when the intervals are adjusted so as to be optimal for the small-page small-size folding book W1 or the folding book W, the conveyor G1 or the thick multi-page folding book W1 or the folding book on the conveyor G W indicates that the upper surface of the rotating delivery fan E1 or the delivery fan E is in contact with the upper surface during conveyance, the paper quality is deteriorated due to rubbing, or the stacking pitch is poor due to the deviation, and the thickness of the origami W1 or W When it was thicker than each interval, problems such as being unable to pass through each interval occurred. On the other hand, when the intervals are adjusted so as to be optimal for the thick multi-page folding book W1 or folding book W, the drop distance from the delivery fan E1 to the conveyor G1 or from the delivery fan E to the conveyor G is as follows. The small and small-sized origami W1 or Fold W has a bounce on the conveyor G1 or the conveyor G, and there is a problem such as bending or a poor stacking pitch on the conveyor G1 or the conveyor G. occured. As described above, when the interval between the delivery fan E1 and the conveyor G1 or the delivery fan E and the conveyor G is optimally adjusted to one thickness, there is a problem in the signature W1 or the signature W with the other thickness. . Also, it could not be adjusted to suit both thicknesses.

  In order to solve this problem, there is known a folding and unloading apparatus A2 of Patent Document 2 as shown in FIG. 4 in which the distance between the delivery fan E1 and the conveyor G1 in the conveyance path not using the chopper folding mechanism F can be adjusted. It has been. The origami carrying apparatus A2 divides the conveyor G1 into a first conveyor 80 and a second conveyor 81, and the belt 82 of the first conveyor 80 is stretched over the pulley 83, the pulley 85 and the pulley 84, and the second conveyor 81 The belt 86 is stretched around a pulley 87 and a pulley 88. The first conveyor 80 is fixed to the shaft 89 with the shaft 89 as a turning center by turning the handle of the adjusting unit (not shown) without changing the position of the pulley 83 linked to the external transport device (not shown). The plate 91 and the shaft 91 fixed to the other end of the plate 90 and the pulley 84 rotatably attached to the shaft 91 and the pulley 87 of the second conveyor 81 are moved in a direction to approach or separate from the delivery fan E1. . Further, the pulley 88 of the second conveyor 81 is moved in the direction opposite to the moving direction of the pulleys 84 and 87 with the shaft 91 as the turning center. For example, when the origami W1 changes from a small page to a multi-page, the belt 82 of the first conveyor 80 is moved away from the delivery fan E1, and the belt 86 of the second conveyor 81 is moved to the delivery fan E1. Move in the direction of approach. On the contrary, when the signature W1 changes from multiple pages to small pages, the belt 82 and the belt 86 are moved in the reverse direction.

  However, in the case of using the above-mentioned booklet carry-out device A2 in the conveyance path using the chopper folding mechanism, for example, as shown by a two-dot chain line portion in FIG. 4, the axial direction of the delivery fan (E) and the conveyor G1 The conveyance direction of the folding book (W) becomes parallel, the outer peripheral lower end surface (Ea) of the rotation trajectory of the delivery fan (E) contacts the second conveyor 81, and cannot be used in this state. Therefore, the second conveyor 81 is deleted, and the first conveyor is moved to the position of the pulley (84) in the two-dot chain line portion of FIG. 4 where the belt (82) of the first conveyor (80) can receive the signature (W). It can be considered that the upstream side of (80) is extended. In this case, without changing the position of the pulley 83 linked to the external transfer device of the first conveyor (80) on the downstream side of the transfer, the pulley (84) on the upstream side of the transfer is moved angularly around the shaft 89 as the turning center. The upper surface of the belt (82) is inclined, and the interval between the outer peripheral lower end surface (Ea) of the rotation path of the delivery fan (E) and the upper surface of the belt (82) is large on the conveyance upstream side and small on the conveyance downstream side. Become. Therefore, the conveyance downstream end of the folded book (W) falling from the delivery fan (E) sequentially comes into contact with the wide conveyance upstream side from the conveyance small downstream side on the upper surface of the belt (82). In the process, defects such as overlapped pitch defects due to bending or misalignment of the signature (W) occur.
