Description

Automatic page turning device

Technical Field

The invention relates to an automatic page turning device, in particular to a touch type automatic page turning device.

Background

At present, there are design schemes for BOOK turning structures at home and abroad, such as an automatic BOOK turning machine of the BOOK turning model BOOK TIME5000 in japan, a Page turner of Michael Donald Banks in the united states, a fully-automatic adjustable Page turning mechanism researched by marte of yanshan university and a foot-operated BOOK turning mechanism researched by majo of grand university and the like. Although the structure solves the problem that the book cannot be turned, the manufacturing cost of the equipment is high, the page turning is flexible, good human-computer interaction cannot be realized, and the engineering practicability is not high.

The invention patent CN201610303929.0 is a humanized automatic page turning device, which is composed of a large plate, a small plate, a controller, a frame, a first servo motor, a first arm, a second servo motor, a second arm, a third servo motor, a third arm, a vacuum generator, a suction nozzle, a CCD camera, a first book fixing clamping strip, a second book fixing clamping strip, a manual page turning button and a stop button, and is based on a machine vision technology, and the page turning action is realized by the blink action of the eye part recognized by the camera, but the device has large volume and is inconvenient to move; the reader closes the eyes for more than 3 seconds to serve as a page turning signal, which is not in line with the reading habit of people; and the device cannot be paged back and forth.

The invention patent CN106113984B discloses a book turning arm device, which comprises a door frame, wherein a bottom plate is arranged in a cavity of the door frame, the bottom plate is connected with the door frame, a power system is arranged below the bottom plate, the power system is connected with a pushing mechanism, the pushing mechanism is connected with the door frame, and the pushing mechanism can push the door frame to rotate around the bottom plate after the power system is started. The automatic page turning mechanism mainly solves the problems that the automatic page turning can not be accurately realized during the scanning of the existing book file, but the page is easily damaged by the mechanism, and the structural volume is too complex to be used in a large range.

Based on the basic book turning principle, the currently commonly used book turning mechanisms mainly comprise four types, namely a suction disc type, a rubbing wheel type, a tape adhering type and a ratchet wheel type. The paper suction principle of the suction cup is simple, the paper suction efficiency is high, and pages cannot be damaged; the rest three structures are complex and all can damage the pages in different degrees.

Therefore, the development of a touchable automatic page turning device is significant for the weak groups with independent reading obstacles, such as the old, the disabled and the like. The device can also be used in important occasions such as libraries, museums and the like, and can protect books as far as possible and prolong the service life of the books on the premise of not influencing reading;
