The collating machine, as the name implies, is to match paper with different page numbers. It can be divided into tower collating machine and horizontal collating machine; according to different paper styles, it can be divided into signature collating machine and single sheet collating machine. The signature collating machine can be divided into a swing arm collating machine and a wheel collating machine according to the different paper feeding methods. Generally, this kind of collating machine is used for glue binding dragons and riding binding dragons; The collating machine can be divided into full-open, folio, four-open, eight-open and sixteen-open collating machines according to the format, and can be divided into bill paper collating machine and ordinary paper collating machine according to the paper thickness. In addition to the above, there is a continuous paper collating machine for the bill industry.
1. Sorting machine
According to the different mechanism and movement mode adopted by the collating machine when holding pages, it is divided into a pincer collating machine and a roller collating machine.
1. Working principle of pliers collating machine
The gripper work is carried out by a reciprocating gripper. The gripper reciprocates once to grip the next signature. When the gripper moves diagonally upward, the jaws open to prepare the gripper. After gripping the signature, the gripper returns diagonally downward, placing the signature on the lower partition with the spine outward. The opening and closing of the jaws is controlled by the cam mechanism. In addition, the gripping mechanism of the pincer collating machine adopts a manipulator, and its structure and process are more complicated. The clamp-type collating machine, because of the reciprocating swing of the gripper, has a large inertial impact, poor working stability, and low speed. It has been rarely used at present.
2. Working principle of roller collating machine
The roller collating machine utilizes the rotating gripper wheel to cooperate with the gripper on the gripper wheel to complete the gripper page. When the gripper wheel drives the gripper to turn to the top, the gripper holds the signature, and turns to release the signature. The post fell backwards on the spacer, with the spine facing inward. The opening and closing of the gripper is also controlled by the cam mechanism, and the gripper wheel rotates once, and the next one or two signatures are gripped.
The roller collating machine has fast collating speed, strong automatic control ability and high collation quality.
Second, the structure of the collating machine
The collating machine is generally composed of a frame, a storage platform, a transmission chain, a transmission device, a paging mechanism, a gripping mechanism, a detection device and a book collection device. Development direction: To develop in the direction of linkage and automation. There have been a page-binding and binding machine, a page-backing machine, a page-pressing machine and a wire-binding line. The page layout is divided into bookends and book blocks. Pasting or nesting additional pages in the order of page numbers is called a matching bookmark.
Method of matching book blocks
Most of the work of matching book blocks is done by machines, or by hand. There are two methods of matching book blocks: one is the matching method and the other is the matching method.
1. Matching method
According to the order of the page numbers of each book, they are superimposed one by one, making it a book block of a book. If there are scrap pages, it is best to add them after the third post. There are a variety of paperback books, hardcover books and picture books, and wireless perfect binding books and books.
2. The nesting method
It is to put each signature on the outside or inside of another signature in order of page number, so that it becomes the book block of a book, and the scrap pages are on the outermost. If you put a cover on the outside, you can use saddle stitching The method is bound into a book. The slip-on method is mainly suitable for binding magazines, brochures, and book publications of about 100 pages.
With book block technology
The book block can be hand-made or mechanical. At present, manual collation is rarely used. Mechanical collation is a mechanism that replaces manual operation, arranges the signatures on the page storage table in order, and is transferred by the collation conveyor belt, and the book block delivery and collection device after the collation is completed.
According to the method of collating, collating machine is divided into collating method and collating method collating machine.
The working principle of the collating method of collating machine: put the signatures to be matched into the book bucket on the storage table of the gripping mechanism in order of page number. At the bottom of the book, and tilt down a block to take away the book, after a book is ready, it will be sent to the receiving part and then transported by the receiving device. The collating machine with collating method can form a linked assembly line with other machines, and can also be used as a stand-alone machine.
If there are multiple or fewer posts in the page collation process, the signature detection device of the page collation machine will send a signal, and the page discarding mechanism will throw out the waste pages or the whole machine will automatically stop. When the signatures are messed up during the transmission process, and the conveyor line is blocked, the messy page control device also causes the machine to automatically stop collating and point out where the messy pages occur. The nesting method collating machine is to wrap a book sticker on the outside of another signature, and the bookbinding method is used as a unit in the saddle stitching linkage machine. Use as a separate collating machine. The production efficiency of the collating machine not only depends on its collating speed, but also depends on the number of book buckets, the quality of the signatures, the format of the books and the number of signatures with inserts.
