Abstract

Disclosed is a paper jam-prevention automatic paper feeder. The paper jam-prevention automatic document feeder is mounted on a paper feeding path and comprises a paper fetching device, wherein the paper fetching device is arranged on the upstream of the paper feeding path so as to feed paper in the paper feeding path. The feeder also comprises a set of transport devices, a dynamic measurement module and a control unit, wherein the set of transport devices is arranged on the paper feeding path for transporting paper; the dynamic measurement module is arranged on the paper feeding path and used for measuring information such as the movement speed and the movement direction of paper; and the control unit is connected with the dynamic measurement module and the paper fetching device for monitoring the movement speed and the movement direction of paper and temporarily stopping the paper fetching device when the movement speed or the movement direction is abnormal. The paper jam-prevention automatic paper feeder can rapidly and accurately respond abnormality of the paper transport condition and reduces phenomena of paper damage due to paper jam.

Description

technical field [0001] The invention relates to an automatic paper feeder capable of avoiding paper jamming and damage to paper due to paper jamming, in particular to an anti-paper jamming automatic paper feeder which directly measures paper dynamics and responds to paper jamming conditions in time. Background technique [0002] see figure 1 , in order to avoid paper jams or paper jams when conveying paper, it is necessary to keep the paper path 10 of the automatic document feeder unobstructed, and to avoid sending more than one piece of paper into the paper path 10 at the same time when feeding. Therefore, generally, the automatic document feeder is provided with a paper separating mechanism 30 downstream of the paper feeding mechanism to avoid repeated paper feeding. Common paper separation mechanism 30 can be as figure 1 As shown in , the mechanical paper separating mechanism 30 formed by using the paper separating wheel 31 and the passive idler 32, or further using the...
