  • it is important that the two signature-shaped sections 48 and 48 are installed to reach the section block formation mechanism 52 corresponding thereto at the substantially the same timing, in order not to generate an error when the section block 55 is carried to a downstream side which will be described below.
  • the signature-shaped section 48 carried to the first section block formation mechanism 52A or the second section block formation mechanism 52B is formed in the section block 55 by the first section block formation mechanism 52A or the second section block formation mechanism 52B, respectively.
  • the section block 55 is formed in the same way by the first section block formation mechanism 52A and the second section block formation mechanism 52B, and thus the forming of the section block 55 in the section block formation mechanism 52 will be described.
  • the signature-shaped sections 48 having reached the section block formation mechanism 52 are discharged into a rectangular parallelepiped space whose four side surfaces and horizontal bottom surface are restricted by restricting members, and are stacked while adjacent two sides thereof are adjusted in the space, forming the section block 55. If the stacked signature-shaped sections 48 reach a desired number previously designated and set and a target section block 55 is formed, the formed section blocks 55 are discharged from the rectangular parallelepiped space. That is, if the number of stacked signature-shaped sections 48 reaches a previously designated set number, an operational signal is output from a controller (not shown).
  • the operation of the movement driving means of the restricting member restricting the horizontal bottom surface is substantially simultaneously performed in the first section block formation mechanism 52A and the second section block formation mechanism 52B .
  • the number of overlapping signature-shaped sections 48 may be designated and set to a desired number which is an integer not less than one in advance.
  • the section block 55 discharged from the section block formation mechanism 52 is received by the carrying surface of the carrying conveyor 53A of the delivery mechanism 53 installed at a lower side of the section block formation mechanism 52.
  • the carrying conveyor 53A is stopped when receiving the section block 55, and after receiving the section block 55, the carrying conveyor 53A is operated at a proper timing and carries the received section block 55 to a downstream side.
  • the carrying conveyor 53A When carrying the section block 55, the carrying conveyor 53A simultaneously carries the two section blocks 55 and 55 discharged from the first section block formation mechanism 52A and the second section block formation mechanism 52B.
  • the two section blocks 55 and 55 should be simultaneously present in the section block folding-in-two unit 6 installed at a downstream side of the section block formation unit 5, while the section block 55 formed by the first section block formation mechanism 52A carried to a downstream side in the carrying direction while folded in two by the section block folding-in-two unit 6, the section block 55 formed by the second section block formation mechanism 52B is stopped and stood by on the carrying surface of the standby conveyor 53B which is a downstream part of the delivery mechanism 53 if necessary.
  • the section block 55 having reached the chopper folding mechanism 61 which is the section block folding-in-two unit 6 with the delivery mechanism 53 is retracted to a predetermined folding-in-two location of the section block support plate (not shown) by a retracting means (not shown) of the chopper folding mechanism 61. Then, the drive means 61b is operated, and the chopper folding blade 61a is reciprocated upward and downward, tapping substantially a central widthwise location of the section block 55 retracted to the folding-in-two location from the upper side.
  • the section block 55 tapped by the chopper folding blade 61a is press-fitted to a lower side from an opening formed in the section block support plate, and a central widthwise location thereof is inserted between close outer circumferential surfaces of the folding roller pair 61c installed by disposing close parts on the outer circumferential surface thereof on a lower side of the opening such that the counterpart circumferential surfaces of the folding roller pair 61c are displaced and rotated to a lower side.
  • the section block 55 a central widthwise location of which is inserted between the folding roller pair 61c is sandwiched by the folding roller pair 61c to be folded in two at a central widthwise location, and is discharged to a lower side by the rotation of the folding roller pair 61c, and a signature-shaped print product 65 whose section block 55 is folded in two is formed.
  • the signature-shaped print product 65 discharged by the folding roller pair 61c is received by the delivery fan 61d installed at a lower side of the folding roller pair 61c, reaches the carry-out conveyor 61e due to the rotation of the delivery fan 61d, is transferred from the delivery fan 61d to the carrying conveyor 61e, and is carried out from the print product production device 1 by the conveying conveyor 61e.
  • the continuous paper W guided to a guide path of the continuous paper W branched by the angle bar mechanism 8 is retracted into the sheet formation integration unit 7 by the first drag roller mechanism 71 and the second drag roller mechanism 72 and is guided to a horizontal guide path of the continuous paper W at a downstream side of the second drag roller mechanism 72.
  • the single sheet-shaped print product 79 formed by the sheet formation mechanism 73 is carried to the sheet stacking mechanism 76 for stacking and integrating the single sheet-shaped print product 79 by the first carrying mechanism 74 and the second carrying mechanism 75.
  • the carrying speeds of the first carrying mechanism 74 and the second carrying mechanism 75 are set to be higher than the moving speed of the continuous speed W due to the first drag roller mechanism 71 and the second drag roller mechanism 72, and thus a predetermined interval is generated between the front and rear single sheet-shaped print products 79 as the print products 79 are carried by the first carrying mechanism 74 and the second carrying mechanism 75.
  • the single sheet-shaped print products 79 carried while the predetermined interval is generated therebetween by the first carrying mechanism 74 and the second carrying mechanism 75 are discharged into a space (stacking space) of the sheet stacking mechanism 76 installed at a downstream side thereof, for stacking the single sheet-shaped print products 79 from the second carrying mechanism 75 and are stacked in the space.
  • a side surface restricting location by a restricting member for restricting a downstream side of the single sheet-shaped print product 79 in the carrying direction in correspondence to the movement direction size of the stacked single sheet-shaped print products 79 is changed. Further, the single sheet-shaped print product 79 having reached the stacking space is stacked while the two adjacent sides thereof are adjusted by fine vibrations of the side restricting member for restricting two adjacent side surfaces perpendicular to the bottom surface of the stacking space. Further, the bottom surface restricting member of the stacking space is lowered according to the amount of the single sheet-shaped print products 79 stacked in the stacking space based on a preset control reference. Thus, the single sheet-shaped print products 79 having reached the stacking space are not stacked while exceeding an upper end of the side surface restricting member.
  • the stacked single sheet-shaped print products 79 stacked in the stacking space reaches a predetermined amount, the stacked single sheet-shaped print products 79 are discharged from the stacking space through a proper means or method.
  • the single sheet-shaped print product 79 can be stacked in the stacking space more efficiently.
  • the guide path of the continuous paper to the second downstream unit row can be made shorter as compared with the case where the first downstream unit row and the second downstream unit row are branched as a path exceeding the first downstream unit row by installing the first downstream unit row and the second downstream unit row in series at a downstream side of the digital printing unit 3, and thus it is possible to reduce papers damaged when the single sheet-shaped print product 79 is produced.
  • the print paper surface monitoring unit 9 installed at a downstream side of the digital printing unit 3 may be omitted.
  • the retraction means of the chopper folding mechanism 61 may extend to exceed a predetermined folding-in-two location of the section block support plate, and the section block 55 formed by the section block formation unit 5 may be installed to reach a downstream side of the section block folding-in-two unit 6 while not being folded in two.
  • the present invention is available as a print product production device which can selectively produce a print product obtained by digitally printing a continuous paper, cutting the continuous paper, and folding and binding a cut paper sheet, for example, a signature-shaped print product such as a newspaper, and a print product obtained by digitally printing and cutting a continuous paper, for example, a single sheet-shaped print product such as a direct mail or an advertisement.
