According to the thickness detection device of the utility model, each driven wheel is provided with one transmission block and one thickness detection sensing device, so that each driven wheel can independently detect the thickness of paper currency which passes through the driven wheel, and the thickness of each position of a whole piece of paper currency can be recorded comprehensively and accurately, and therefore, paper currency thickness detection accuracy can be greatly improved.
Description
Technical field
The utility model relates to the device of paper currency sorter, relates in particular to a kind of measuring thickness device.
Background technology
In paper currency sorter, there are the banknote path and the measuring thickness device that pass through for bank note, described measuring thickness device comprises two groups of thickness measuring wheels, described two groups of thickness measurings wheel comprises row's driving wheel and row's engaged wheel, lay respectively at the both sides of banknote path, general, driving wheel plays the effect of twisting with the fingers coin, is provided with thickness measuring sensing device after engaged wheel, and the banknote thickness by it is detected.The thickness of bank note is generally in 0.1 millimeter, so require high to the degree of accuracy of thickness measuring.In existing paper currency sorter, one row's engaged wheel is concatenated into wheels by a driven shaft, all be connected with a thickness measuring sensing device at the two ends of driven shaft, in the time that bank note passes through, the thickness of bank note itself makes engaged wheel produce displacement, and thickness measuring sensing device converts this displacement to corresponding thickness data the thickness of bank note is distinguished.But, in the time that bank note passes through this group engaged wheel, if certain section of bank note is blocked up, the engaged wheel corresponding with this section of bank note can produce relatively large displacement, and then the larger displacement of related whole piece driven shaft generation, affect real test result, for example, when having dirty bank note to judge, effects on surface just easily makes mistakes, detect to check the technical requirement of forge or true or paper money also more and more higher by banknote thickness, existing measuring thickness device cannot well meet this requirement already.
Summary of the invention
The purpose of this utility model is to provide a kind of measuring thickness device, can greatly improve the degree of accuracy that thickness measuring wheel detects, and solves the problem in background technology.
For achieving the above object, the utility model adopts following technical scheme:
A kind of measuring thickness device, comprise a main drive shaft and a driven shaft, described main drive shaft is provided with the wheels that are made up of some driving wheels of a row and main drive shaft one, the pattern length of described wheels and the size of bank note are suitable, it is characterized in that, on described driven shaft, activity cross-under has row's drive block, and described drive block is provided with a minor axis, on described minor axis activity cross-under have one with the suitable engaged wheel of described driving wheel, a thickness measuring sensing device is pressed on described drive block top.
As preferably, described drive block is provided with baffle plate, and described baffle plate is provided with a salient point, and described thickness measuring sensing device comprises a flat board, and on described flat board, slip cap is connected to one and pushes away bar, described in push away bar one end be provided with and cut somebody's hair, described in the top of cutting somebody's hair be pressed on described salient point; Described pushing away on bar is also socketed with a back-moving spring, cuts somebody's hair upper described in the top, one end of described back-moving spring is pressed in, and other end top is pressed in dull and stereotyped one end; The described bar that pushes away is provided with a permanent magnet, and described flat board is provided with the corresponding sensor element of some and described permanent magnet.
Measuring thickness device in the utility model, configure a drive block and thickness measuring sensing device to each engaged wheel, make each engaged wheel independently carry out thickness detection to the bank note by it, the thickness of each position of entire paper coin can be carried out to comprehensive and accurate record, greatly improve the degree of accuracy that detects banknote thickness.
