Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Referring to Fig. 1 and Fig. 2, roller follower 8 is arranged on one end of third connecting rod 7, the middle part of third connecting rod 7 is hinged in frame 1, one end of the other end of third connecting rod 7 and second connecting rod 6 is hinged, the other end of second connecting rod 6 is connected with cam bawl 5, one end of first connecting rod 4 is hinged in frame 1, the other end of first connecting rod 4 is connected with cam bawl 5, active roller 9 is arranged in frame 1, inverted cam 3 is coaxially fixedly connected with active roller 9, inverted cam 3 is in transmission connection with driving wheel 2, driving wheel 2 is arranged in frame 1, on inverted cam 3, be provided with outer ring 11 and inner ring 12, on inverted cam 3, be provided with two outer rings to inner ring transition zone 13 and two inner rings to outer ring transition zone 14, and outer ring is arranged alternately to outer ring transition zone 14 to inner ring transition zone 13 and inner ring, every outer ring is formed with a unidirectional step surface 15 in outer ring to inner ring transition zone 13 and outer ring 11 joints in outer ring 11, outer ring is formed with outer ring to the unidirectional step surface 16 of inner ring transition zone to inner ring transition zone 13 and inner ring 12 joints, every inner ring is formed with an inner ring to the unidirectional step surface 18 of outer ring transition zone to outer ring transition zone 14 and outer ring 11 joints, inner ring is formed with the unidirectional step surface 17 of inner ring to outer ring transition zone 14 and inner ring 12 joints on inner ring 12, cam bawl 5 is slidably arranged in outer ring 11, inner ring 12, outer ring to inner ring transition zone 13 and inner ring in outer ring transition zone 14, in frame 1 baffled 10, when third connecting rod 7 is descending, can press down baffle plate 10.
Below in conjunction with accompanying drawing, working procedure of the present invention is described.
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, the present invention is applied in finance device, the transmission of the paper of signing for user.Cam bawl 5 is in inner ring 12, now, roller follower 8 is separated from active roller 9, roller follower 8 can not transmit paper with active roller 9, baffle plate 10 does not have pressurized simultaneously, and baffle plate 10 blocks paper in normal position, now, the high instrument of clapping of paper equipment has been taken photograph, and roller follower 8 does not affect high instrument the taking pictures to paper of clapping.The paper of user's signature is clapped instrument at equipment one end height and has been taken after photograph, need to be in position can this paper of the automatic recovery, now, paper is placed in active roller 9, starting driving wheel 2 clockwise rotates, driving wheel 2 drives inverted cam 3 to rotate, inverted cam 3 drives active roller 9 to rotate, thereby cam bawl 5 is in the interior slip of inner ring 12, cam bawl 5 is encountered the unidirectional step surface 17 of inner ring and to outer ring transition zone 14, is entered outer ring 11 from inner ring under the control action of first connecting rod 4, in this process, cam bawl 5 promotes third connecting rod 7 rotations by second connecting rod 6 and rotates, thereby make roller follower 8 push down paper with contacting of active roller 9, simultaneously, third connecting rod 7 presses down baffle plate 10 makes baffle plate 10 abdicate paper path, cam bawl 5 is 11 interior rotations in outer ring, due to the traffic direction of cam bawl 5 back to outer ring unidirectional step surface 15, cam bawl 5 can not change position and running state, along with driving wheel 2, being rotated further of inverted cam 3 and active roller 9, active roller 9 coordinates the other end to equipment by paper sheet delivery with roller follower 8, realize a road continuous rotating motion, one tunnel upset is fixed a point and presses down the conveying that paper is carried out in translational motion.
Referring to Fig. 6, Fig. 7, Fig. 8 and Fig. 9, after paper sheet delivery, roller follower 8 and active roller 9 need to be departed from and close paper path.Now, driving wheel 2 rotates counterclockwise, driving wheel 2 drives inverted cam 3 to rotate counterclockwise, inverted cam 3 drives active roller 9 to rotate counterclockwise, thereby cam bawl 5 is 11 interior slips in outer ring, cam bawl 5 is encountered the unidirectional step surface 15 in outer ring and is entered inner ring 12 from outer ring to inner ring transition zone 13 under the control action of first connecting rod 4, in this process, cam bawl 5 promotes third connecting rod 7 by second connecting rod 6 and rotates upwards rotation, thereby make roller follower 8 depart from and open with active roller 9, simultaneously, third connecting rod 7 unclamps baffle plate 10 makes baffle plate 10 risings bar up paper path, cam bawl 5 is in the interior rotation of inner ring 12, because the traffic direction of cam bawl 5 is back to the unidirectional step surface 17 of inner ring, cam bawl 5 can not change position and running state, thereby make roller follower 8 and active roller 9 keep departing from open configuration, make equipment wait for the transmission of the paper of user's signature next time.
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8 and Fig. 9, this mechanism provides driving wheel 2 also to arrive gradually the connecting rod that one point union keeps this position self-locking from continuing to be converted into unidirectional movement, and driving wheel 2 oppositely continues be converted into connecting rod reversing motion and arrive gradually second point position and keep this position self-locking.Single power source be driving wheel 2 realize Liao Yi road continue rotation, a road simultaneously driving crank linkage mechanism uniaxially to first position motion and after remain on this position, and without the rotational position of accurate Calculation rotating power source; And at power source, be driving wheel 2 while oppositely continuing rotation, again simultaneously driving crank linkage mechanism reverse to the motion of second point position and after remain on this position, and without the rotational position of accurate Calculation rotating power source.Compare traditional method, saved power source, can reduce position transducer again, simplified hardware circuit.
