Abstract
The utility model discloses a detection apparatus for paper money door state, including the driving shaft of paper money door pull rod, the both ends at the driving shaft are fixed to paper money door pull rod, the driving shaft still be equipped with the motion separation blade, be equipped with respectively on the rotatory orbit of motion separation blade open the door the alignment sensor with close the door the alignment sensor, still fixing on the driving shaft and setting up a count carousel, the count carousel is perpendicular with the driving shaft, and it is fixed that the driving shaft passes count carousel axle center, the rotation of count carousel is swept the off -plate and is set up a count sensor that suits with the count carousel. Through fixing at the epaxial grating disc of initiative and its count sensor that corresponds, the system can learn that whether the driving shaft is always in the motion. And through comparing default values and grating count, can accurately learn whether the paper money door reachs predeterminedly to close the door and open the door the position. The subordinate parameter only need be regarded as to traditional opening door sensor and close door sensor, and the fine motion alignment sensor has been omitted to direct the province. Do not have traditional detection blind area completely, reach the accuracy and economical beneficial effect.
Description
Technical field
The utility model relates to a kind of automatic teller machine self-checking unit, particularly relates to a kind of pick-up unit of paper money door state.
Background technology
In the design of paper money door, conventional U-shaped photoelectric sensor and motion catch, as the location of paper money door motion starting point and terminal, use simple straight motor as power source, generally further comprises the Micro-positioning sensor of system for position self-inspection.In the course of the work, electric motor starting or brake receive corresponding inductor signal in system just can change action, is subject to the impact of the factor such as manufacturing accuracy, SR, and during motor complete stall, motion is wanted turn LAP more.And different batches or different paper money door this section of stroke of the degree of wear not identical yet, sensor will give warning in advance and cannot accurately early warning in other words.May cause not closing completely because external force stops at closing time like this, but closing door sensor but reports paper money door by mistake and shut, such situation be absolutely not allow to occur on finance device.
Motion catch is called for check frequency by the distance between plural U-shaped photoelectric sensor simultaneously, because each sensor does not detect motion catch in this section of distance.Time when paper money door moves to check frequency because of fault or other factor stop motions, system cannot judge the motion state of paper money outlet door in time, and intelligence just can send fault-signal after waiting for motion time-out, causes very big hidden danger like this for fault handling.
Utility model content
In order to solve the problems of the technologies described above, the utility model object be to provide a kind of can the pick-up unit of continuous detecting paper money door motion state.
The pick-up unit of a kind of paper money door state described in the utility model, comprises the main drive shaft of paper money door pull bar, and paper money door pull bar is fixed on the two ends of main drive shaft; Main drive shaft be also provided with motion catch, motion catch rotational trajectory be respectively equipped with enabling alignment sensor and close the door alignment sensor; It is characterized in that, main drive shaft is also fixedly installed a counting rotating disk, counting rotating disk is vertical with main drive shaft, and main drive shaft is fixed through counting disk axes; A sensor for countering adapted with counting rotating disk is set outside the surface sweeping of counting turntable rotation.
Described counting rotating disk is a grating disc.
Described sensor for countering is a U-shaped photoelectric sensor, and counting turntable rotation track is by the U-shaped induction groove of described U-shaped photoelectric sensor.
The utility model advantage is, by being fixed on the sensor for countering of grating on main drive shaft and its correspondence, system can learn whether main drive shaft is moving always.And by comparison default value and raster count, accurately can learn whether paper money door arrives predetermined closing the door and opening position.Traditional open door sensor and pass door sensor only as auxiliary parameter, need directly dispense Micro-positioning sensor.There is no traditional check frequency completely, reach accurate and economical beneficial effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
According to Fig. 1, paper money door 3 connects driven axle 2, and paper money door 3 is connected by two pull bars 4 with main drive shaft 1, and two pull bars 4 arrange the two ends with main drive shaft 1 respectively.One end of main drive shaft 1 is provided with motion baffle plate 7.Motion baffle plate 7 rotary motion trace is also provided with close the door alignment sensor 6 and enabling alignment sensor 5.Close the door alignment sensor 6 and enabling alignment sensor 5 all adopts U-shaped photoelectric sensor, and motion baffle plate 7 is when rotated by the U-shaped induction groove of U-shaped photoelectric sensor.Also be fixedly installed a grating disc 9 in main drive shaft 1 one end, the plane of grating disc 9 is vertical with main drive shaft 1, and main drive shaft 1 is through the axle center of grating disc 9.The grating movement locus of grating disc 9 is provided with a sensor for countering 8.Sensor for countering 8 adopts U-shaped photoelectric sensor, and the grating motion of grating disc 9 is in the U-shaped induction groove of U-shaped photoelectric sensor.
The course of work of the present utility model is, drive pull bar 4 to move to open or close paper money door 3 when main drive shaft 1 rotates, grating disc 9 and motion baffle plate 7 are rotated with main drive shaft 1 and rotated.When main drive shaft 1 rotates, the grating disc 9 be fixed on main drive shaft 1 rotates simultaneously, when grating disc 9 is rotated through in the U-type groove of sensor for countering 8, the breach of upper EDS maps makes sensor for countering 8 export a series of continuous square wave, system is by the change of square wave, can determine that main drive shaft 1 is in rotation status, and rotate how many angles.The square wave wave number arrived by Determination and the wave-number registration preset, can learn whether paper money door 3 is in completely to close the door or door opening state, and leave the detecting position postpone of close the door alignment sensor 6 and alignment sensor 5 of closing the door in motion baffle plate 7, can also learn that paper money door 3 is in motion or halted state by square-wave variations.When paper money door 3 stop motion under abnomal condition, system can send alerting signal in time, improves security.
Grating disc 9, sensor for countering 8, motion baffle plate 7 and alignment sensor 6 of closing the door combine, and can also realize fine motion measuring ability, can save traditional fine motion detecting sensor.Such as under the door state of pass, when main drive shaft 1 turns to open, change according to the signal detecting alignment sensor 6 of closing the door and start, the square wave quantity that count sensor 8 sends exceedes self-locking stroke, reach paper money door 3 and open very little stroke, when determining that paper money door 3 can be opened, then rotate backward closedown paper money door 3.
The utility model structure is simple, is convenient to produce and application.
