Abstract

The utility model relates to a counter for counting sheet articles, which comprises a shell, wherein a power supply, an infrared switch and a counting processor connected with the infrared switch are arranged in the shell, and a display connected with the counting processor is arranged on the side wall of the shell on which a reading needle is arranged, and an elastic element for ejecting the reading needle outwards is arranged in the shell. One end of the reading needle extends from the shell, and the other end of the reading needle is connected with a slice which is positioned between the transmitting end and the receiving end of the infrared switch. The reading needle is used as a sensor, and the needle tip of the reading needle is used for scraping the step surface after sheet articles are staggered to drive the slice to cut off the infrared light beam continuously, and thus, the counting purpose is realized.

Description

Counter

The utility model belongs to a kind of counting assembly, and particularly a kind of being suitable for checked the counter that counting is handled to sheet article.

In the prior art, the counting of checking of sheet articles such as paper, banknote, metal or nonmetal thin plate mainly contains two kinds of methods.A kind of is that method of counting is checked in traditional craft, and another kind is to adopt specialized apparatus to check counting to handle, and wherein, most typical is exactly the paper money counter of checking banknote.The work efficiency of checking by hand counting is lower, and labour intensity is big, counts inaccurately, can not adapt to the requirement of checking counting on a large scale.Paper money counter is as the specialized equipment widespread use at present of checking banknote, and this machine mainly is made up of body, motor, gearing, banknote dispensing devices, infrared switch, counting processor, display etc.The banknote dispensing devices launches bundled banknote, and be fed forward one by one, infrared switch is then launched infrared light beam from a side of banknote, opposite side receiving infrared-ray light beam from banknote, when banknote passes through between the transmitting terminal of infrared light beam and receiving end, infrared light beam is blocked, receiving end does not receive infrared light beam, after banknote passes through, infrared light beam can pass through in the gap between two banknotes, receiving end just can receive infrared light beam, thereby, whenever sent a banknote, infrared light beam is received once, as count signal, after counting processor accumulative total, data can show on display with the received number of times of infrared light beam.In order to check the true and false of banknote, magnetic inspection device, purple light pipe, signal processor and alarm or the like also are housed on paper money counter, so that in the process of counting, check the true and false of banknote, increase work efficiency.The problem that this paper money counter exists is, 1, counting rate is slow, inefficiency, banknote must be one by one passes through between the transmitting terminal of infrared switch and receiving end, and each all will have certain interval between opening, therefore, limit the speed of counting, can't satisfy the requirement that banknote in enormous quantities is checked counting.2, in checking the process of counting, banknote and dispensing devices exist friction, can cause the wearing and tearing of banknote, have shortened the serviceable life of banknote.3, big, the complex structure of the volume of paper money counter, the difficulty of debugging is bigger, and breaks down easily, and cost is also higher, and its application is subjected to certain restriction.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, changes traditional counting mode, and the counter that a kind of counting rate is fast, volume is little, easy to use is provided.

The utility model is achieved in that

It has a housing, power supply is housed in housing, infrared switch and the counting processor that matches with infrared switch, on the sidewall of housing, be equipped with and count the display that processor is connected, reading needle is housed on housing, the flexible member that reading needle is outwards ejected is housed in housing, one end of reading needle stretches out outside the housing, the other end is connected to section, described section is between the transmitting terminal and receiving end of infrared switch, utilize reading needle as sensor, streak on sheet article staggers the stepped appearance surface of rear edge with the needle point of reading needle, drive in the section, move down, in the process that moves, constantly cut off infrared light beam, thereby realize the purpose of counting.

The utility model compared with prior art has following advantage:

1, adopt reading needle as sensing element, changed traditional counting mode, and the slight distance on the stepped appearance surface that forms after utilizing paper to stagger makes, and reading needle is upper and lower beats, by cutting off the infrared light beam that infrared switch is launched, finish the work of counting again through the counting processor, therefore, counting rate of the present utility model is fast, only need stroke on the stepped appearance surface after paper staggers, just finish the counting work of this bundling note machine or paper, significantly improved the efficient of work.

2, the distance that moves according to reading needle, the utility model can identify the paper sheet thickness conterfeit note different with banknote, can also identify according to the degree of roughness of paper surface very, conterfeit note, from and increased the measure of two discriminations, simultaneously, can also automatically identify the misread phenomenon that produces because of hanging togother, therefore, the accuracy height of the utility model counting, counting is reliable.

3, simple in structure, easy to use, cheap, volume is little, in light weight, its profile such as same pen, easy to carry, and need not AC power, be not subjected to the restriction of working environment, condition and use technical ability, anyly can easily use per capita, and, in the process of using, do not rub with banknote, thereby, can not damage banknote.

4, range of application is wide, and the utility model not only can be used for the counting of checking of banknote, also can be used for the counting work of checking of all kinds of paper, and the counting of checking that can also be used for various sheet articles such as metal or nonmetal thin plate is handled.
