DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for supplying a print book to a bookbinding machine.

[0002]

Conventionally, in order to supply a printing book to a bookbinding machine, a plurality of printing books (signatures) are erected vertically and stacked vertically (in such a manner that the fold is either upward or downward). And stack them) and arrange them in the socket of the bookbinding machine. As for the method of supplying print books there, at present the proportion of manual work by workers is high, and the automatic print book supply device (autoloader) only under limited bookbinding specifications. However, the versatility was extremely low. On the other hand, as a labor-saving technique for the manual work, there is a long feeder a shown in FIG. This is limited to printing books such as those used in letterpress printing, and can be applied to printing books that are light and stiff.However, the printing books themselves used for gravure or offset printing are of the same paper quality. As shown in FIG. 7, when a large number of printing books b are placed on the feeder a and supplied to the bookbinding machine as shown in FIG. 7, misfeeding occurs at the receiving portion of the bookbinding machine due to the large weight of the printing books. In addition, in the case of a print book that spans several pages due to its stiffness, there is a difference in the total thickness of the printed book between the fold side and the opposite side in the stacking state, and the rear end side This causes collapse, and a large number of printed books cannot be placed. This is a problem when the automatic printing book supply device (autoloader) is used. That is, in the automatic printing book supply apparatus, a plurality of printing books are arranged in a vertically stacked state on a supply path having a certain length and arranged side by side. In the case of a book, the total thickness in the stacked state is different between the upper end portion and the lower end portion, and collapse occurs on the rear end side. Therefore, in the case of a printing book of paper quality used in gravure printing or offset printing, a worker manually divides a plurality of printing books into a fixed number of small copies without using the long feeder, and prints a small number of copies. Are curved and aligned before being supplied to the bookbinding machine. Under such working conditions, it is difficult to improve the efficiency of the entire bookbinding process, and it is impossible to save labor.

[0003] In view of the above circumstances, the present invention is intended to reduce the thickness of the upper and lower ends of a printed book in the state of vertical stacking even when the book is stiff and weak, and therefore, after the vertical stacking. An object of the present invention is to stabilize an accumulation state without causing collapse at an end portion side, and to save labor in supply of printing copies.
