Description

[Detailed description of the invention] [Industrial application field] The invention relates to a machine that efficiently and automatically supplies printed books to a so-called collating machine for aligning pages necessary in the bookbinding process. This is an improved version of the automatic book feeding machine filed by the present applicant in Japanese Patent Application No. 12291/1983.

[Prior art and its problems] That is, in the feeding machine of Japanese Patent Application No. 56-12291, a stack of printed books sent from a conveyor is suspended from both sides by clamping side plates and carried to a printed book box. The book is opened and dropped onto the book box. For this reason, if the material of the printing press is weak or the quantity is small, there is a drawback that the middle part of the printing book may become loose and fall during transportation or get caught in a machine. Furthermore, because the books are dropped onto the book box, they are not often neatly stacked on top of the remaining books, and there is also the drawback that the feeding does not proceed smoothly. Furthermore, when the size of the printed books differs, the interval between the clamping side plates must be adjusted each time, which results in poor workability.
