A hollow guide post cover is fixed on the desktop, and the guide post cover can accommodate the guide post to move up and down.

The lower surface of the support plate has a circular groove with the same diameter as the guide post.

The book clamping mechanism also includes a guide rod. The lower part of the guide rod is connected to the clamping air claw, and the upper part is connected to a slider. The slider is located inside the guide rail and can be driven by a mobile motor to drive the clamping air claw on the guide rail. to move in.

The guide rails are a plurality of criss-cross tracks.

The method for returning books using the self-service book returning device of the library according to claim 1, characterized in that: comprising the following steps:

Step 1. Scan the barcode of the book on the book scanner until the book is confirmed to be recognized;

Step 2. Place the book in the return area at the beginning of the conveyor belt of the conveyor mechanism;

Step 3. The conveyor belt starts to carry the books and move forward;

Step 4. When the book placed on the conveyor belt moves to the end of the conveyor belt, the front part of the book is conveyed to the support plate on the pallet of the rotating platform;

Step 5. After the books are separated from the conveyor belt, the rotating motor of the rotating platform drives the pallet to rotate 90 degrees, and rotates an empty support plate on the pallet to face the conveyor belt for the delivery of the next book;

Step 6. When the support plate loaded with books rotates above the guide post, the cylinder drives the guide post to move upward through the through hole on the pallet to lift up the support plate carried by the pallet above the through hole;

Step 7. The mobile motor drives the idle clamping air claw to move to the top of the lifted support plate, and the air claw cylinder drives the clamping air claw to pick up the book;

Step 8. The moving motor drives the clamping claws that have picked up the books to move along the guide rails, and transfers the books to the top of the book return table. The clamping air claws are opened, and the books are placed on the book return table of the category determined according to the barcode. .

The self-return book process is over, and the staff only need to complete the book shelf work when they are free.

The above steps 5 and 7 are key steps of the present invention. The four-position rotating platform used in step 5 has effectively improved the working efficiency of the self-service book returning system. Compared with the defect that the existing book returning device can only return one book at a time, this rotating platform can complete a book The loading of another book is also completed while the book is clamped, which improves the work efficiency by 3-4 times; in step 7, the mobile motors loaded on each clamping device perform book clamping in an orderly manner according to computer control, which can Guarantee the efficiency and accuracy of the entire book returning device.

Beneficial effects: the present invention uses barcode scanning to identify books, and uses mechanical devices to automatically transmit, carry, pick up and place books, and the cost of the entire self-service book returning device is low; at the same time, it uses a unique four-position rotating platform and The clamping air claws that move orderly in each guide rail further improve the working efficiency and working precision of the book return device, and have high commercial value in the modern society where human resources are scarce.
