Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of book cutting machines, and more particularly to a three-side book cutting machine capable of accurately positioning books and automatically feeding books. BACKGROUND

[0002] The three-side book cutting machine is a book processing device capable of cutting three sides of a book except the binding side. It has fast cutting speed, neat three-side cutting of books, and simple operation of workers, and is therefore widely used in various book processing plants.

[0003] The current automatic book cutting machine is equipped with an automatic book feeding mechanism, including a conveying belt, a clamping jaw, a positioning mechanism, etc. However, the general positioning mechanism only simply positions the books through two adjacent and perpendicular baffles, and then feeds the books to the lower side of the cutting knife through the clamping jaw. Although the consistency of the cut books in the external dimensions can be ensured, the positioning effect is poor.

[0004] Some book sellers have higher requirements for the position of the pattern or text part on the cover of the new book, that is, the distance between the pattern or text part and the two sides of the book cover (i.e. the up-down position of the pattern or text on the book cover) should be within the design size. Although the practical three-side book cutting machine can make each book the same in external dimensions, due to the errors in the binding or glued books, there will be a certain deviation (up or down) in the position of the pattern or text on the book cover after cutting. For example, it is stipulated that a certain pattern or text part on the cover should be at the center position of the diagonal line of the book, so that the distance to the up-down sides is the same, and the distance to the left-right sides is also the same. However, the current positioning mechanism cannot accurately position, resulting in the pattern or text on the book cover after cutting. SUMMARY

[0005] In view of the deficiencies of the prior art, the present application provides a three-side book cutting machine capable of accurately positioning books and automatically feeding books, which ensures the accuracy of the position of the pattern or text on the book cover after cutting.

[0015] 1. inputting specific positions of a specified pattern or text on a book in a controller;

[0016] 2. moving the moving frame after the book is conveyed to the positioning placement plate, so that the push plate contacts the binding side of the book, and then moving the push plate to make the binding side of the book contact the push plate, while the book is located between the first clamping jaw plate and the second clamping jaw plate;

[0017] 3. moving the adjusting plates on both sides to be close to the book until the adjusting plates contact the side edges of the book;

[0018] 4. detecting the actual positions of the specified pattern or text on the cover of the book by the detection camera, and transmitting the actual positions to the controller, and the controller analyzes the distances between the specified pattern or text and the two sides of the binding side of the book;

[0019] 5. driving the adjusting plates and the book to slowly move by the driving motor, so that the book moves left and right on the positioning placement plate to adjust the cutting position of the book, and the position of the specified pattern or text is detected in real time by the detection camera until the specified pattern or text reaches the required position;
