Separation method and separation mechanism for slice medium

Abstract

The invention discloses a separation method and a separation mechanism for a slice medium. The separation method comprises the steps that a separation roller drives the slice medium to move in the paper feed direction and a paper unwinding roller arranged opposite to the separation roller rotates intermittently in the paper unwinding direction, so that separation of the slice medium is achieved. The separation mechanism comprises a machine frame, the separation roller, the paper unwinding roller, a driving mechanism, an eccentric part, a one-way bearing and a thumbing rod, wherein the separation roller and the paper unwinding roller are oppositely arranged on the machine frame, the driving mechanism driving the separation roller to rotate, the eccentric part is arranged on the separation roller in a sleeved mode, the one-way bearing is arranged on the paper unwinding roller and can rotate in the paper unwinding direction, and the thumbing rod is arranged on the one-way bearing and can be thumbed by the eccentric part. The separation roller drives the slice medium to move in the paper feed direction and the paper unwinding roller rotates intermittently in the paper unwinding direction. According to the separation mechanism and the separation method, the paper unwinding roller rotates intermittently and stops rotating at other times, and therefore conveying resistance to the single slice medium is reduced, and smooth conveying of the single slice medium is achieved.

Description

technical field [0001] The invention relates to a separation method and a separation mechanism of sheet medium. Background technique [0002] Existing sheet medium processing devices, such as printers, scanners, currency detectors, cash dispensers and other sheet medium processing devices, are often equipped with a separation mechanism to separate multiple sheets of sheet media in order to improve the convenience of use. Such as paper, banknotes, bank cards, etc. are fed one by one into the sheet medium processing device. [0003] Such as figure 1 As shown, the existing sheet medium separation mechanism includes a frame, at least one set of conveying rollers 110, a separation roller 120, a reverse roller 130 and a driving assembly, and at least one set of conveying rollers 110 and separation rollers 120 respectively pass through the first rotating shaft 210 and the second rotating shaft 220 are supported on the frame, and the reverse roller 130 is supported on the frame by...

AI Technical Summary

Problems solved by technology

[0004] The problem with this separation mechanism is that when a single sheet medium enters between the separation roller 120 and the reverse roller 130, the reverse roller 130 and the separation roller 120 are respectively in contact with both sides of the sheet medium, wherein the separation roller 120 The single sheet medium is always driven to be conveyed downstream, and the reversing roller 130 is always driven to convey the single sheet medium upstream, causing the single sheet medium to wrinkle due to the opposite direction of force on the surface, and it cannot move smoothly.
