Abstract
The utility model relates to a paper detection device, in particular to a device for detecting paper, invoice and the like by using an infrared light function. The paper detection device comprises a photoelectric installation bracket, wherein an upper bracket (31) and a lower bracket (32) are arranged on the installation bracket, the upper bracket (31) is provided with a receiving unit (1) and the lower bracket (32) is provided with a transmitting unit (5). The paper detection device is characterized in that the receiving unit (1) comprises a receiving photoelectric tube (11) and a positioning ring (12), the positioning ring (12) is arranged on the upper bracket (31), the receiving photoelectric tube (11) is arranged in the positioning ring (12), the transmitting unit (5) comprises a transmitting photoelectric tube (51) and a positioning ring (52), the positioning ring (52) is arranged on the lower bracket (32), and the transmitting photoelectric tube (51) is arranged in the positioning ring (52). The paper detection device has the characteristics of high recognition rate, skilled design and the like; and according to the structure of the paper detection device, the defect of the reflection type detection technology is overcome, the probability of misjudgment is reduced, and the efficiency of recognizing paper is increased.
Description
Technical field
The utility model relates to a kind of sheet detecting apparatus, particularly utilizes the infrared light effect to realize the device that paper, invoice etc. is surveyed.
Background technology
In the prior art; General sheet detecting mode is reflection; This kind detection mode is feasible when paper is common paper or non-printed on both sides; But along with the accurate requirement of printing of paper and the spread overwide areas of advertisement, the easy appearance judges by accident when using the reflection detection mode to survey, thereby causes paper or invoice to be scrapped.
Summary of the invention
The purpose of the utility model is to provide a kind of sniffer of stablizing, being used for paper reliably.
The purpose of the utility model can realize like this, designs a kind of sheet detecting apparatus, comprises the photoelectricity mounting bracket; Mounting bracket is provided with upper bracket and lower carriage; Upper bracket is installed receiving element, and lower carriage is installed transmitter unit, and said receiving element comprises reception photoelectric tube and centring ring; Centring ring is installed on the upper bracket, receives photoelectric tube and is arranged in the centring ring; Said transmitter unit comprises emission phototube and centring ring, and centring ring is installed on the lower carriage, and emission phototube is arranged in the centring ring.
The utlity model has the discrimination height, characteristics such as be skillfully constructed.This structure can be avoided the deficiency of reflective Detection Techniques, reduces the probability of erroneous judgement, improves the paper identification efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model preferred embodiment.
Embodiment
Below in conjunction with embodiment the utility model is done further to describe.
As shown in Figure 1, a kind of sheet detecting apparatus comprises the photoelectricity mounting bracket; Mounting bracket is provided with upper bracket 31 and lower carriage 32; Upper bracket 31 is installed receiving element 1, and lower carriage 32 is installed transmitter unit 5, and said receiving element 1 comprises reception photoelectric tube 11 and centring ring 12; Centring ring 12 is installed on the upper bracket 31, receives photoelectric tube 11 and is arranged in the centring ring 12; Said transmitter unit 5 comprises emission phototube 51 and centring ring 52, and centring ring 52 is installed on the lower carriage 32, and emission phototube 51 is arranged in the centring ring 52.
Said receiving element 1 also comprises darkening ring 13, and darkening ring 13 is arranged on the lower end of centring ring 12.The center of darkening ring 13 is provided with a through hole, and this through hole is over against the receiving end that receives photoelectric tube 11.The setting of darkening ring 13 can prevent that light that non-emission phototube sends from causing the generation of judging by accident to the influence that receives photoelectric tube.
Adjusting screw 6 is set on the said mounting bracket, and the distance between the last lower carriage is at 2～6mm.The photoelectricity mounting bracket, last lower carriage is adjustable apart from guaranteeing in 2～6mm scope, and the paper that can adapt to respective thickness was to guarantee that paper was unobstructed.
During work, the infrared ray that the infrared reception photoelectric tube 11 on the receiving element 1 receives by 51 emissions of the emission phototube on the transmitter unit 5.When in the paper road paper or bill being arranged, because the obstruct of paper, the infrared ray of power valve 51 emissions can not be received pipe 11 and receive.At this moment, the electric signal that is sent on the master control borad is a low level, and master control borad is made respective reaction to this low level signal, judges having or not of paper or invoice with this.The emission phototube 51 outstanding parts on paper road down that form; When paper passes through the paper road; Can emission phototube 51 lip-deep dusts and tiny paper scrap be taken away, thereby reach the purpose of cleaning, it can be used more the grade under the environment comparison condition of severe of dust.
The utility model also has the function of clear light dateline surveying paper and pinpoint while.
