Description

Photoelectricity sucker on the paper money counter

The utility model relates to paper money counter, the photoelectricity sucker on particularly a kind of paper money counter.

Renminbi in the production overall process, its quantity and count and must be absolutely correct, thereby the counting machine that is adopted must be guaranteed number paper absolutely accurates.Existing high speed paper money counter is owing to complex structure, and manufacturing cost is higher, thereby it is restricted on using.The photoelectricity sucker that also has a kind of counting machine, owing to adopt the vacuum pump negative pressure to inhale paper, so gas circuit is big more, noise is just loud more.

The purpose of this utility model provides the photoelectricity sucker on a kind of paper money counter, and it can be counted accurately, and is anti-interference, has good reliability and stability.

Electronic power-actuated physical construction, electronic component and the negative pressure that is provided by air pump are provided photoelectricity sucker on a kind of paper money counter described in the utility model, described physical construction comprises that one is provided with the sucker of inhaling the paper gas circuit, the separation groove of inhaling the paper spilehole that has that on sucker, distributes equably and be provided with, each separation groove setting and be close on the groove concave surface and leave the separation point in a piece of paper gap, the paper output trough that below the separation point, forms, and the sucker cover plate that is positioned at the sucker bottom surface; Described electronic component comprises at the back mounted photistor of each separation point, the light emitting diode that on each separation point, is provided with, printed-wiring board (PWB) that on sucker, is provided with and integrated circuit block, and brush of being installed and slip ring, its circuit is input 15V voltage, one end ground connection of photistor, light emitting diode and resistance, the other end of photistor and resistance inserts integrated circuit block, outputs on the counter then.

The utility model is specifically designed to the new money or the securities of counting after cutting edge, and collect mechanical, electrical, gas is integrated, adopts photoelectric counting, and the emission of far infrared photoelectricity is accepted the pipe Tibetan is gone in the sucker to count.Because far infrared photoelectricity volume is little, light beam is thin, low in energy consumption, the life-span is long, again through technical testing and screening, has therefore guaranteed the accuracy that photoelectricity sucker counting machine is counted.This machine function is complete, and counting is accurate, and rational in infrastructure, maintenance capacity is few, and is anti-interference strong, good reliability, and good stability is compared with the paper money counter in the society, on the industry, more embodies its advantage place.

Below in conjunction with drawings and Examples the utility model is elaborated.

Fig. 1 is the main TV structure synoptic diagram of the photoelectricity sucker on a kind of paper money counter.

Fig. 2 is the A-A cut-open view shown in Fig. 1.

Fig. 3 is the backsight structural representation of above-mentioned photoelectricity sucker.

Fig. 4 is the B-B cut-open view shown in Fig. 3.

Fig. 5 is the circuit diagram of above-mentioned photoelectricity sucker.

Referring to Fig. 1 to Fig. 4, electronic power-actuated physical construction, electronic component and the negative pressure that is provided by air pump are provided the photoelectricity sucker on a kind of paper money counter.

The photoelectricity sucker is a rosette, and sucker 1 is provided with inhales paper gas circuit 2, also is provided with equally distributed eight circular arc separation grooves 3 on the sucker 1.Each circular arc separation groove 3 is provided with four and inhales paper spilehole 4, has 32 spileholes 4.At each circular arc separation groove 3 place a separation point 5 is set, this separation point 5 is close on the concave surface of circular arc separation groove 3, but leave certain clearance, this gap is to adjust to according to paper sheet thickness to pass through a piece of paper smoothly, but can not pass through two pieces of paper.The photoelectricity sucker whenever rotates a circle and can pass through eight paper, has produced eight count pulses thus, and so circulation can count up to 209 paper p.s..

As long as it is just passable that sucker 1 can hold a piece of paper, influence is not very big to negative pressure to counting, influence is very big to the separation counting and separation point 5 tips are in the gap of arc-shaped concave bottom, when this gap too hour, it is smooth separation to occur, and the phenomenon of breaking paper is arranged, and when the gap is too big, inhale two opening in the time of will separation occurring, only produce a count pulse this moment, thus the occurrence count mistake.In addition, separation point 5 can't jagged and wedge angle.

Sucker 1 and the sucker cover plate 6 that is positioned at sucker 1 bottom surface are by eight socket head cap screws, 7 fastening forming, in case gas leakage, sucker 1 can break product paper, and therefore, sucker cover plate 6 requires to make not only thin but also smooth, and product paper angle can be passed through smoothly.

When sucker 1 was counted, every a piece of paper angle all will be formed with paper output trough 8 by separation point 5 below separation point 5.A photistor 9 is equipped with at each separation point 5 back side, and infraluminescence diode 10 is housed over there.Printed-wiring board (PWB) 11 and integrated circuit block 12 are set on sucker 1, and brush 13, signal slip ring 14 and power slip rings 15.

See Fig. 5 again, its circuit is input 15V voltage, the end ground connection of photistor, infrarede emitting diode and resistance 470K, and the other end of photistor and resistance 470K inserts integrated circuit block CMOS4078, outputs on the counter then.

When paper angle during by separation point 5, light source is blocked by the paper angle, makes photistor 9 produce a counting electric signal, sends into counting circuit.Eight separation points 5 are housed on the sucker 1, and sucker 1 whenever revolves and turns around, and just can pass through eight paper.Eight photistors 9 and eight infrarede emitting diodes 10 are arranged on eight separation points 5, after being merged into a signal, the signal of sucker 1 inner eight photistors 9 just can see off, an integrated circuit block COMS4078 who is installed, the signal of eight photistors 9 is delivered to eight input ends of integrated circuit block, the output terminal of integrated circuit block is then guided to sucker 1 outside by a brush 13 and is transported to counting circuit, counting circuit, integrated circuit and eight power supplys that infrarede emitting diode is used, provide by the another one brush, two slip rings 14 are just arranged on the sucker 1 like this, 15.Sucker 1 needs brush that the circuit in the sucker is connected with power supply, digital circuit in the machine in running up, and brush graphite is penetrated into the surface of slip ring, makes that slip ring is bright and clean, lubricated, contact is good.Interior circuit and external circuit have three connecting lines, and power vd D15V, signal wire and ground wire, ground wire utilize the metal shell of sucker, can guarantee the counting absolutely accurate.

It is sufficient that the negative pressure that air pump provided is wanted, if negative pressure suction deficiency is not only inhaled paper and had some setbacks, and breaks product easily, general negative pressure is less demanding, but also span will be arranged, and about about 0.05-0.07MPa, inhales paper smoothly to guarantee the photoelectricity sucker.

Photoelectricity sucker of the present utility model is a vitals on counting machine, plays the important and pivotal role, and it is smooth to make the photoelectricity sucker inhale paper, at first will make the photoelectricity sucker be in best separation state all the time, and the ability separation is good like this, and counting accurately.Smooth when separation is exactly the sucker separation well, do not break paper, two only opening only allows a piece of paper to pass through by a happy chancely; Counting accurately then requires counting and paper actual number to match, and is guaranteed that with its circuit the two is inter-related.
