Thickness detection apparatus of slice medium

Abstract

The invention relates to a processing technology of a slice medium, especially to a detection apparatus for detecting thickness of a slice type valuable document in a financial self-service device. The detection apparatus comprises a module frame, a driving shaft, at least one driven wheel assembly, and an inductor. The module frame is used for installing and carrying parts. The two ends of the driving shaft are installed on the module frame by a bearing. The driven wheel assembly contains a driven wheel and an elastic support; one end of the elastic support is fixedly installed on the module frame and the driven wheel is assembled to the other end in a rotating mode to form a free end; an arc spring plate is arranged at the module frame by corresponding to the driven wheel assembly; the part, opposite to the driven wheel, of the free end of the elastic support is in contact with the arc spring plate for assembling; and a detection block is fixedly installed at one side, opposite to the driven wheel, of the elastic support. The inductor is fixedly installed on the module frame by being opposite to the detection block and is used for detecting a displacement value of the detection block in a non-contact mode.

Description

technical field [0001] The invention relates to a processing technology for thin sheet media, in particular to a detection device for detecting the thickness of thin sheet valuable documents in financial self-service equipment. Background technique [0002] In the financial self-service equipment, in order to check each sheet of valuable documents (such as banknotes, checks, money orders, etc.) Image recognition, thickness detection, magnetic information detection and other identification methods are carried out on the separated single sheet valuable documents to ensure the authenticity of the processed thin sheet valuable documents, among which the thickness detection of banknotes is an essential means of identification. At present, sheet-type valuable documents are generally made of special materials into a thin sheet-shaped medium with a certain thickness characteristic. The counterfeit valuable documents and spliced ​​valuable documents that appear at present are trying...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims to solve the problem that the effective magnetic flux of the thickness detection module is affected by the contact direction of the reference axis and the detection axis in the existing sheet medium thickness detection device, which cannot be effectively kept in the vertical direction, and the fatigue life of the elastic support is low due to long-term bending stress The problem is to provide a sheet medium thickness detection device that can ensure that the contact direction between the driving shaft and the driven wheel is in the vertical direction, and can effectively prevent the fatigue life of the elastic support from being reduced
