Magnetic levitation type slice medium thickness detecting device

Abstract

The invention relates to a device for metering thickness, in particular to a magnetic levitation type slice medium thickness detecting device. The magnetic levitation type slice medium thickness detecting device comprises a fixed frame, a reference shaft, a detection idler wheel mechanism, an elastic packaging board and a magnetic sensor. The fixed frame is provided with a pair of installation side walls and a base board, and a placing slot is arranged in the base board. Two ends of the reference shaft are installed on the pair of installation side walls of the fixed frame through bearings, and a reference roller is fixedly sleeved on the reference shaft. The detection idler wheel mechanism comprises a support frame, and an idler wheel is arranged on the support frame through a bearing, a magnetic element is fixed on a side surface, corresponding to the idler wheel, of the support frame, and the detection idler wheel mechanism is freely placed in the placing slot of the fixed frame. The elastic packaging board is fixedly arranged on the base board of the fixed frame, the detection idler wheel mechanism is packaged in the placing slot and provides elasticity for keeping close to the reference roller for the idler wheel, and a position, corresponding to the magnetic element of the detection idler wheel mechanism, of the elastic packaging board is provided with a magnetic penetrating hole. The magnetic sensor corresponding to the position of the magnetic penetrating hole is fixed on the fixed frame and used for detecting displacement of magnets in a non-contact manner.

Description

technical field [0001] The invention relates to a device for measuring thickness, in particular to a magnetic levitation type thickness detection device for detecting the thickness of sheet-type valuable documents in financial self-service equipment. Background technique [0002] In the financial self-service equipment, in order to inspect each sheet of valuable documents (such as banknotes) processed in batches one by one, it is necessary to separate the stacked sheet of valuable documents one by one, and then separate the separated single sheet of valuable documents Valuable documents are identified by image recognition, thickness detection, magnetic information detection and other identification methods to ensure the authenticity of the processed thin sheet valuable documents. Thickness detection is essential in the entire detection, and thickness detection information can be used To judge the authenticity of the processed thin sheet valuable documents, it can also judge ...

Problems solved by technology

[0005] Obviously, the existing magnetic levitation thickness detection device has many parts and complex mechanism, and the unavoidable mechanical wear of the detection wheel's rotation around the axis may cause the thickness detection device to fail to correctly reflect the value of the flakes passing through. The thickness value of the file, which leads to the inaccuracy of the detection device, therefore, it is necessary to find a solution to the above technical defects
