[0003] The large-scale perfect binder in the prior art usually includes the following main components: 1. Feeding / collating part; 2. Bookmark correction and positioning system; 3. Back milling device; 4. Glue brushing system; 5. Back paper pasting: paste a layer of reinforcing paper or decorative paper on the spine to enhance the strength and aesthetics of the spine; 6. Clamping and bonding part: after the bookmark is glued, it will be fed into the clamping device, and then the bookmark will be firmly bonded together under a certain temperature and pressure; 7. Side glue coating and curing: Side glue is applied to the edges of the book to solidify the bookmark. The function of fixing the pages and protecting the overall structure of the book; 8.

The processor 92 is connected to the binder body, and the plurality of high-speed cameras 91 are respectively arranged on a plurality of feeding stations of the feeding and collating part of the binder, and are used to shoot partial images of the surface of the book sheet taken by the feeding clamp, and the processor 92 is electrically connected to the high-speed camera 91. The high-speed camera 91 transmits the captured surface image of the book sheet to the processor 92 for comparison, analysis and judgment. If a mistake in printing occurs, an alarm and shutdown operation are performed in time, thereby avoiding the misprinted books from being used in large quantities.

[0043] The implementation principle of a book misprint identification system for a binder in an embodiment of the present application is as follows: the binder processes multiple booklets through 1. a feeding / collating part; 2. a bookmark correction and positioning system; 3. a back milling device; 4. a glue brushing system; 5. a back paper; 6. a clamping and bonding part; 7. a side glue coating and curing; 8. a slotting and creasing unit; 9. a cover assembly area; and 10. a compaction and cooling system to form a book. However, since each feeding station is manually fed with stacks of books, misprints may occur from time to time. Therefore, a high-speed camera 91 and a processor 92 are provided at the feeding / collating station. The high-speed camera 91 is used to photograph the surface of the booklet clamped by the clamping device, and then the high-speed camera 91 compares and analyzes the photographed picture with the standard picture in the processor 92 to determine whether there is a raw material feeding error.

[0044] Since the feeding station uses clamping feeding, it is easy to have more or less copies. When the problematic books with more or less copies are sent out and pass through the conveyor belt 7 supported by the weighing drive 3 and the discharge follower 6, the weighing sensor 5 measures the weight of the books on the conveyor belt 7. According to the set reasonable weight range, when the weight of the book exceeds the set range, the drive unit 8 applies force to the discharge follower 6. While the discharge follower 6 rotates, one end of the conveyor belt 7 tilts downward, so that the books with more or less copies fall into the defective collection box.

[0045] At the same time, in order to further prevent misjudgment of weighing due to book stacking, which causes normally processed books to be mistakenly discarded, a photoelectric sensor 12 is connected to the frame 1. The photoelectric sensor 12 is set toward the conveyor belt skin 7, and the photoelectric sensor 12 is located in the cover area of ​​the protective cover 11. By irradiating the books and distinguishing the reflected signals, it is identified whether there is stacking of books, so as to detect and recycle the books that are mistakenly discarded due to stacking.
