Description

Sheet Media Alignment Device

technical field

The invention relates to a sheet medium aligning device, which is used for sorting and aligning checks, banknotes, envelopes, cards and other sheet mediums.

Background technique

Alignment devices for sheet-like media, commonly known as joggers, were first used in the printing field for sorting and aligning paper materials, newspapers, magazines, etc. Early joggers were complex and bulky due to the large size of paper stock, newspapers or magazines.

With the increase of application fields, traditional paper joggers cannot meet the needs of banks, post offices and other fields for sorting and aligning small sheet media, such as checks, banknotes, envelopes, cards and other sheet media. In order to solve this problem, US Patent No. US7431285, titled "A Vibrating Jogger for Aligning Check-Type Papers", provides a solution, the entire disclosure of which is hereby incorporated by reference.

As shown in FIG. 1 , the back of the tray 5 of the vibrating jogger is connected to the ring 54 , the eccentric wheel 71 is connected to the central shaft 73 , and the ball bearing 8 is sleeved on the eccentric wheel 71 and located in the oblong hole 57 of the ring 54 . When the DC motor (not shown in FIG. 1 ) drives the eccentric wheel 71 to rotate through the central shaft 73, the driving ring 54 moves up and down, thereby driving the tray to move vertically up and down, thereby impacting and separating the paper.

The disadvantage of the above scheme is that the ball bearing 8 is in direct contact with the oblong hole 57, and both are rigid materials. Therefore, when the DC motor drives the ball bearing to rotate in the oblong hole, the noise generated by the collision between the two is relatively large, and it is difficult to eliminate .
