  Commercial prints such as books (hereinafter referred to as commercial prints) sent to the folding device with the printing surface completely dry and newspapers sent to the folding device with the printing surface not completely dry A rotary press folding apparatus that can be applied to both printed materials (hereinafter referred to as newspapers) is required to have high quality for both commercial printed materials and newspapers.

  The folding device A3 as shown in FIG. 10 has the same upper conveying belt 93 and lower conveying belt 94 sandwiching the folding book W regardless of whether or not all the folding books W use the chopper folding mechanism F. Be transported. Here, when the force sandwiched between the conveyor belts 93 and 94 is increased in order to reliably convey the folded book W, there is a problem that the printed surface of the newspaper in a state where the printed surface is not completely dried becomes dirty. On the other hand, when the force sandwiched between the conveyor belts 93 and 94 is weakened, the folding book W is displaced or bent, and the folding accuracy of the commercial printed matter using the chopper folding mechanism F that folds again in parallel with the traveling direction is deteriorated. Occurred. Thus, when the force which pinches | folds the signature W of the conveyance belts 93 and 94 is optimized for one printed matter, the problem occurred in the other printed matter. Further, the force for sandwiching the origami W could not be adjusted to be suitable for both printed materials.

Further, even if the printed surface of the commercial printed matter in a state where the printed surface is completely dried is strongly sandwiched between these belts 33, 37, 42, no stain is generated.

  On the other hand, the signature W2 is guided by the paper guide 51 or the paper guides 54 and 55 of the paper guide means 5A or 5B having a gap with the collar body D and the back surface of the guide plate 30B, and the belt 72 and the fourth of the third conveyor 7 The printed surface is sandwiched between the belt 82 of the conveyor 8 with a strength that does not contaminate and is sent to the delivery fan E.

  As a result, the printed surface of the newspaper in a state where the printed surface is not completely dried does not become dirty. Further, a slight shift or bend of the signature W2 is corrected at a portion where the third conveyor 7 and the fourth conveyor 8 drop onto the delivery fan E.

  Further, the contact surfaces of the belts 72 and 82 that form the second transport paths 2A and 2B with the folding book W2 are compared with the contact surfaces of the belts 33, 37, and 42 that form the first transport paths 1A and 1B. By providing a small friction coefficient, the second conveyance paths 2A and 2B can be conveyed without causing stains on the printing surface of the newspaper. Conversely, the first conveyance paths 1A and 1B having a large friction coefficient can be used for commercial printing. Can be reliably conveyed, and the effect of preventing contamination of the printing surface and improving chopper folding accuracy is increased.

  In the embodiment according to the present invention, the method for switching the transport path of the present invention is such that the paper guide 51 of the paper guide means 5A is removed, and the belt 33 of the extension 31A of the first conveyor 3A is attached to the outer periphery of the casing D. The first conveyance path 1A is formed by the surface of the guide plate 30A and the sandwich conveyance unit 3, and the belt 33 and the guide plate 30A are separated from the casing D, and the paper guide 31 is attached. The third conveyor 7 and the fourth conveyor 8 form the second transport path 2A.

  In another embodiment of the present invention, the belt 33 of the extension part 31B of the first conveyor 3B is brought into contact with the outer peripheral surface of the casing drum D, and the first conveying path 1B is formed between the surface of the guide plate 30B and the pinch conveying part 3. The belt 33 and the guide plate 30B are separated from the casing drum D, and the second conveying path 2B is separated by the back surface of the guide plate 30B, the fixed paper guides 54 and 55, and the third conveyor 7 and the fourth conveyor 8. Form.

  As described above, there are two conveyance paths: a first conveyance path that conveys the folded book released from the casing to the chopper folding mechanism, and a second conveyance path that conveys the folding book to the delivery fan without facing the chopper folding mechanism. The folding apparatus according to the present invention has a very simple switching method, and the path is changed to a different path, and the commercial printed material and the newspaper signature are conveyed in each path, and the printed surface is in a completely dry state. An effect is obtained in which the quality of the printed matter of both newspapers in a state where the printing surface is not completely dried can be maintained well.
