Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Embodiment
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the rotary gate module of depositing and drawing in bank machine cash dispensing port comprises body, gate sheet 8, toggle and motor 2; Body is made of base plate 9, two side plates 3 and top board 1, and gate sheet 8 is arranged at the front end face of body by gate rotating shaft 21, and gate sheet 8 can be realized around gate rotating shaft 21 rotations the opening and closing of bodies; Be set with torsion spring 23 in the gate rotating shaft 21, torsion spring 23 1 ends are fixed on the gate sheet 8, and the other end is fixed on the top board 1 of body.
In body, be provided with a main shaft 6, main shaft 6 two ends are located on the biside plate that is oppositely arranged by bearing, crank 13 1 ends of toggle are fixed on the main shaft 6 and rotate with main shaft 6, the other end of crank 13 and the connecting rod of toggle 14 1 ends are hinged, and the other end of connecting rod 14 and gate sheet 8 are connected; Toggle is two, is separately positioned on the two ends of main shaft 6.In body, be provided with a cam 18 by camshaft 19, be provided with the cam curved surface guide groove at cam 18 and cooperate with cam bawl 22.
Cam bawl 22 is arranged on the crank 13 of toggle.The output shaft of motor 2 connects a small synchronous pulley 15, is set with large synchronous pulley 17 at camshaft 19, has installed around Timing Belt 16 on small synchronous pulley 15 and the large synchronous pulley 17.
Motor 2 is fixed on internal body and rotates by Timing Belt 16 driving cams 18, is provided with switch 11 at body and is electrically connected with motor 2 by circuit board 12.
Cam 18 is provided with sensor bezel 20 and rotates with cam 18, be provided with gate opening position transducer 4 near the side plate inwall of cam 18 and closing gate position transducer 5 is electrically connected with motor 2 at body, gate opening position transducer 4 and closing gate position transducer 5 are positioned on the movement locus of sensor bezel 20.
Being provided with block sensor 10 at the side plate 3 of body is electrically connected with motor 2.
Being provided with illuminating lamp 7 at the side plate 3 of body is electrically connected with circuit board 12.
Specifically referring to Fig. 3 and Fig. 4, when module receives that access paper money is uncapped instruction, circuit board 12 control motors 2 forwards, Timing Belt 16 is by 18 rotations of large synchronous pulley 17 band moving cams, thereby driving cam bawl 22 by the curved surface gathering sill on the cam 18 moves upward, driving crank 13 rotates up, pass through crank and connecting rod movement, operator link 14 drives gate sheet 8 around gate rotating shaft 21 Unscrews, when sensor bezel 20 trigger gate open site sensors 4, gate sheet 8 is finished opening action, motor 2 stalls; In like manner, when module receives that instruction is covered in the pass, 2 counter-rotatings of circuit board 12 control motors, Timing Belt 16 drives cam bawl 22 and moves downward by 18 counter-rotatings of large synchronous pulley 17 band moving cams, thereby driving crank 13 is rotated down, thereby the drive crank and connecting rod movement, thus drive gate sheet 8 rotary closings, when sensor bezel 20 trigger gate off-position sensor 5, gate sheet 8 is finished closing motion, motor 2 stalls.Wherein, when sensor bezel 20 trigger gate off-position sensor 5, cam bawl 22 is in cam 18 angle of repose curved surfaces, toggle is in the dead-centre position, and when pressed by external force gate sheet 8 was arranged, toggle was failure to actuate, cam mechanism is failure to actuate, and this moment, module had double self locking.When motor 2 motions have delay, cam 18 rotation low-angles, cam bawl 22 still is in cam 18 angle of repose curved surfaces, and toggle still is in the dead-centre position, and this moment, module still had double self locking.In gate sheet 8 closing process, can realize in operation by block sensor 10, prevent from that hand from time not regain and clamped by gate sheet 8.
