Is a table 5 for transporting the signature 4 in the upright state, and a second for changing the signature of the inclined portion 6 from the lying state to the upright state.
An inclined portion 7 is provided, and a transport belt 8 is provided between the first inclined portion 6 and the second inclined portion 7. 2nd inclined part 7
A roller 9 for pressing the signature 4 on the belt 8 toward the second inclined portion 7 is provided at a position opposite to the roller 9.

The signatures 4 on the belt 8 of the first inclined portion 6 are stacked such that the propeller side is located at the front end side in the advancing direction, the fold side is located backward, and the signatures 4 are partially shifted from each other. Part 6
When the belt 8 moves to the second inclined portion 7 from above, the signature 4 is erected along the vertical direction by the pressing force of the roller 9, and the signature 4 is erected and aligned on the table 5.

However, the bookbinding machine 1 is operated by the signature feeder 3.
When the signature 4 is supplied to the roller 9, if the signature is thin, the stiffness is weak, or the coefficient of friction of the surface is small, the pressing force of the roller 9 makes the roller 9 crumpled.
Phenomena such as jamming, skew, and oblique alignment are likely to occur, and the signature feeder 3 cannot be used.

In order to solve such a problem, Japanese Patent Laid-Open No. 1-64938 entitled "Method and apparatus for supplying a signature to a signature extracting machine" discloses a method of stacking signatures laid on a table lifter. Raise the table lifter, stop the rise by detecting that the upper surface of the print book has reached the predetermined position by the photoelectric tube, and insert the sorting pin into the signature,
The table lift is slightly lowered to create a gap for sorting, and a conveyor is inserted.However, when inserting the sorting pins, the back of the signature is broken and pushed out in the pressing direction. There is a problem in that when the shingles are stacked side by side, the heights of the fold side and the pallet side are different, so that it is difficult to perform a large amount of sorting processing.
