The specific embodiment

Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.

Shown in Fig. 1-5: the deviation correcting device of present embodiment is installed in the entrance of flaky medium transfer system, comprise upper slide 1, lower skateboard 2, actuating device 3, correction wheel 4, rubber tape 5, control agent enters the control of this device to managing 6, control agent withdraws from the control of this device to managing 7, and control correction wheel 4 accurately is parked in the sensor 8 of a certain position, and the main control module of controlling each parts.

Wherein, upper slide 1 and lower skateboard 2 constitutes the passage of medium transport, and to managing 6 and to managing 7 two ends that are separately positioned on this passage, correction wheel 4 is a rhombogen in irregular shape, and its angle is a circular arc, also can be oval body; Correction wheel 4 is installed on the lower skateboard 3, and the position over against correction wheel 4 on the upper slide 1 offers an oblong " groove "; Actuating device 3 be fixed on lower skateboard 2 below, actuating device 3 is connected with correction wheel 4, is used for driving correction wheel 4 and rotates; Be wound with rubber tape 5 on the correction wheel 4, this rubber tape also can be replaced by the bigger material of other friction coefficient, and rubber tape 5 can travel forward by actv. friction flaky medium, and does not damage medium.Offer 2 holes on the correction wheel 4, sensor 8 is installed in the next door of correction wheel 4, the profile of sensor 8 is a U-shaped, two two holes of rectifying of sensor 8 facing to correction wheel 4, sensor 8 can detect these 2 holes on the correction wheel 4, thereby can send control correction wheel 4 signals that accurately stop to main control module.

The principle of work of the deviation correcting device that the utility model provides is as follows: after entering deviation correcting device in the gap of flaky medium between upper slide 1, lower skateboard 2, at first trigger managing 6, to managing 6 signal is sent to main control module, master control module controls actuating device 3 begins to drive 4 rotations of correction wheel; Correction wheel 4 is wheels of the fitfull " rhombogen or oval body " of a uniqueness, adopts the correction control of 4 pairs of flaky mediums of correction wheel of this shape more accurate; When the long limit of correction wheel 4 rotates to the upright position, can stretch into upper slide 1 in the oblong " groove " of correction wheel 4, thereby make the bank note distortion; Rely on the friction force between rubber tape 5 and the bank note, bank note is moved forward.

As can be seen from Figure 2, an angle of crossing through accurate Calculation is arranged between correction wheel 4 and the reference plane A, again referring to Fig. 6, the friction force F that bank note is subjected to can be decomposed into perpendicular to the component F1 of reference plane A and the component F2 that advances along the B direction, bank note moves closer to reference plane A, and component F2 makes bank note advance along the B direction simultaneously; After bank note was adjacent to reference plane A, component F2 just made bank note advance towards the B direction along reference plane A.

Along with the operation of bank note, when bank note triggers after managing 7, sensor 8 can send signal, and control correction wheel 4 stops on the position of long limit maintenance level, thereby makes the passage free time.If system needs, corresponding driving mechanism can be set drive bank note and withdraw from along the C direction, because the long limit of correction wheel 4 stops at level attitude, minor face does not stretch in the gap between upper slide 1, the lower skateboard 2, bank note will uncrossedly withdraw from smoothly.

Deviation correcting device of the present utility model can be used for the transmission of any flaky medium, and as bank note, card, bill or the like, application comprises: paper money recognition machine, paper money counter, automatic teller machine and bill handling apparatus or the like.Continuous rotation by the correction wheel, make let-in flaky medium between correction wheel and upper slide, produce distortion, rely on the friction force of the rubber tape on the correction wheel, make let-in flaky medium discontinuous mobile to the reference plane of a side, thereby make let-in medium alignment reference plane, move towards let-in direction simultaneously, realize follow-up work.That is: arbitrarily put into flaky medium, can both lean on the reference plane alignment.Simultaneously, when flaky medium withdraws from along former passage,, can accurately control the correction wheel and stop at a certain level attitude accurately, thereby not hinder the passage that medium withdraws from, realize that smoothly former passage withdraws from, avoid loss by two holes on the sensor correction wheel; This apparatus structure is simple, and is with low cost, safeguard easily and can carry out correction work efficiently.

The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
