  The stopper (5) that receives the sheet print discharged from the sheet-fed printing machine (1) and falls to the stacking unit (8) can be tilted and normally stands. When pulling out, it falls down and passes through without receiving the sheet copy.

  The extraction mechanism (20) installed at a position facing the tiltable stopper (5) is a conveyor belt with a negative pressure from the inside of the conveyor belt (21) in the extraction conveyance unit (30) by the extracted sheet printing book. Suction to the surface of (21) and send to the downstream.

  The transport mechanism section (50) receives the sheet print book extracted by the extraction mechanism section (20), sucks the received sheet print book with a negative pressure, and sends it to the drawing book receiving section (80).

  Then, in the primary transport unit (60), the sheet print is sucked with a negative pressure in the extracted posture and sent to the downstream secondary transport unit (65).

  The extraction operation of the sheet print book is slower than the feeding speed of the printed sheet book that is continuously discharged and accumulated, and the sheet book book can be extracted stably and reliably.

  When necessary at the time of maintenance or the like, the printing book sampling device (10) moves to the escape position as a whole, and opens the back of the printed sheet printing book stacking unit (8).

  The extraction mechanism (20) normally extends so that the finger (36) is close to the stopper (5), and when the printing book extraction device (10) moves to the escape position, the driving direction of the belt is changed. The fingers (36) are retracted in the opposite direction so as not to cause interference during the escape operation.

  The sampling book receiving section (80) has a variable length according to the size of the sheet printing book, and receives the sheet printing book appropriately and reliably.

Since the sheet is sucked and sent to the downstream, the sheet print can be continuously conveyed, and the sheet print can be reliably extracted.

  In the sampling transport section of the sampling mechanism section, the primary transport section and the secondary transport section of the transport mechanism section, the long hole of the vacuum box built inside the conveyor belt sucks the back surface of the conveyor belt to the conveyor belt. The sheet prints are sucked through many negative-pressure holes, and even if the conveyor belt moves, the long holes in the vacuum box communicate with the negative-pressure holes in the conveyor belt, and the negative pressure is used without interruption. The leaf book can be aspirated.

  At the time of pulling out the sheet-printer, the book-binding mechanism protrudes, accepts the unprinted sheet-printer ejected from the sheet-fed printing press, and temporarily retains it so that there is a margin in the pull-out operation. .

  The sheet printing operation can be slower than the feeding speed of the printed sheet book that is continuously discharged and accumulated, and the sheet book can be extracted stably and reliably. .

  Since the printing book sampling apparatus can move to the escape position as a whole and opens the back of the stacking section of the printed sheet printing book, it is easy to work when maintenance is necessary.
