The turning-over body 12 is rotated in accordance with the movement of the frame 6, and when the turning-up body 12 is stopped at the suction position in FIG. 1, the leading end of the binding paper C and the support plate 17 face each other. It is supposed to do.

Next, the operation of the printing machine configured as described above will be described.

Before starting the operation of this printing machine, as shown in FIGS. 1 and 2, the turning-off member 12 is position-regulated by the position-regulating pin 24, and the moving frame 6 is at the position indicated by the chain double-dashed line. It is located in. First, when the binding paper C is supported on the support base 2 and the operation is started in a state in which the binding side is clamped by the clamp device 3, the binding is performed from the edge blowing nozzles 18, 20 and the side edge blowing nozzles 21. Paper C
Is blown onto the edges and both side edges of the sheet, and the edges and both side edges are lifted up, and the uppermost page P is adsorbed by the suction air flow from the adsorption nozzle 19.

On the other hand, the moving frame 6 is moved leftward from the position shown by the chain double-dashed line in FIGS. 1 and 2. At this time, the tension spring 10 in the support arm 9 contracts and the support rod 11 retracts, so that only the position of the moving frame 6 changes. When the tension spring 10 is completely contracted and the support rod 11 is stopped from being retracted, the turning-over portion 12 is moved by the moving frame 6 and the inverted U-shaped flocking tapes 26 and 27 are engaged with each other to support the support base 2 It is rotated and moved without slipping on it. In addition, turning part
Immediately after the movement of 12 is started, the detection sensor 25 no longer detects the moving frame 6, so that the position regulating pin 24 is moved downward and is immersed until it becomes substantially flush with the support base 2, and the position regulating pin 24 moves. There is no obstacle to the movement of the frame 6.

When the moving frame 6 is moved to the left from this position, the turning-off body 12 is rotated counterclockwise in FIG. 1 according to the movement, and the outer circumference of the winding cylinder 16 is rotated as shown in FIG. The top page P of the binding paper C is wrapped. in this case,
Since the turning-off portion 12 winds up the binding paper C from the edge thereof, a negative pressure is hardly generated between the pages P, so that there is no obstacle in turning-up one by one. Further, since the turning-off part 12 rolls up the binding paper C from the edge thereof, the binding paper C is surely turned one by one without being bent or wrinkled.

When the movable frame 6 is further moved to the left from this state, the engaging body 34 is moved along the guide rail 30 and the turning-off body 12 is lifted while being restricted in rotation, as shown in FIG. The uppermost page P is lifted to the upper left side in the figure in the suction wound state. At this time, the suction operation by the suction nozzle 19 is released, air is blown from the releasing spray nozzle 35 to the page P in the turned-off state, and the page P is blown below the turning-off body 12.

After that, when the movable frame 6 is moved to the right, the turning-off body 12 is lowered while being regulated in rotation, and the guide rail 12 is lowered.
The engaging body of the outer ring 14 when moving from above 30 to the support base 2.
38 and the engagement recess 37 of the engagement member 36 engage with each other. For this reason,
As the moving frame 6 moves to the right, the turning-off part
12 rotations can be forced to start,
The rotation can be adjusted so that the front end of the binding paper C and the support plate 17 face each other when the turning-off member 12 is stopped at the suction position shown by the solid line in FIGS.

Further, the moving frame 6 is moved back to the right, and in the middle of the returning, the printing roller 7 prints supplementary items such as a company name at a predetermined position on the next page P. Further, when the moving frame 6 is detected by the detection sensor 25 in the middle of the return, the position regulating pin 24 is moved upward and the turning-off body 12 is regulated in the suction position shown by the solid line in FIGS. The front end of the paper C and the support plate 17 face each other.

Then, while the moving frame 6 is reciprocally moved between the position shown by the solid line and the position shown by the chain double-dashed line,
The next page P of the binding paper C is sucked by the 12 suction nozzles 19, and thereafter, the page turning and printing operations are repeated in the same manner as described above.

The present invention is not limited to the configuration of the above embodiment, and can be modified and embodied as follows.

(1) The pages P of the binding paper C are configured to be lifted one by one by clinging by a mechanical clinging member or adhering by an adhesive tape instead of the suction airflow of the above-mentioned embodiment.

(2) A rubber belt provided on both sides of the upper surface of the support base 2 for preventing slippage between the outer ring 14 of the turning-off body 12 and the support base 2, and a large number of short needles planted on the outer periphery of the outer ring 14. The engagement should be performed.

(3) Sandpaper is used to prevent slipping between the outer ring 14 of the turning-off body 12 and the support base 2 instead of the inverted U-shaped flocking tape.

(4) In the above embodiment, the suction force of the suction nozzle 19 is changed according to the paper quality of each page P of the binding paper C by changing the number of nozzles or the strength of the suction air flow. It should be configured so that it can be changed and adjusted.
