Referring to accompanying drawing 1-4, a kind of gripping body of adaptive any thickness paper money, including in frame 1, setting frame 1 It is vertically directed slide rail 1-1 and is arranged on the paper money being vertically directed on slide rail 1-1 to clamp mechanism and supporting drive mechanism, the paper money There is the upper clamping part 2 of free sliding degree and lower clamping part 4 including being arranged on being vertically directed on bar 1-1 to clamp mechanism, it is described Drive mechanism includes the motor 3-1 being arranged in frame 1, and what is be connected with motor 3-1 output ends is vertical to straight line fortune Motivation structure 3-2, the connecting plate 3-3 being arranged on straight-line motion mechanism 3-2, is arranged between connecting plate 3-3 and upper clamping part 2 Flexible linking device 3-4 and it is arranged between connecting plate 3-3 and lower clamping part 3 and by fixed pulley 3-5, movable pulley 3-6 and steel Cord 3-7 combines the adaptive delay link gear to be formed.The section of the connecting plate 3-3 is in " " " shape.
The upper clamping part 2 includes being arranged on being vertically directed on slide rail 1-1 and section is in "] " the dewclaw sliding block 2-2 of shape And the upper gripper jaw 2-1 on dewclaw sliding block 2-2 is arranged on, the lower clamping part 4 includes being arranged on being vertically directed on slide rail 1-1 The lower claw sliding block 4-2 and lower clamping jaw 4-1 being arranged on lower claw sliding block 4-2;The lower claw sliding block 4-2 is by stage clip 5-1, guiding The resetting-mechanism of bar 5-2 compositions is connected with frame 1.
The fixed pulley 3-5 is symmetrically fixed on the upper end both sides of frame 1, and the movable pulley 3-6 is positioned at lower claw sliding block 3-2 two Side, described steel wire rope 3-7 one end are fixed on connecting plate 3-3 upper surfaces, are middle successively around fixed pulley 3-5 and movable pulley 3-6, another One end is fixed on dewclaw sliding block 2-2 lower surfaces.
The lead 3- that the flexible linking device 3-4 includes being arranged on dewclaw sliding block 2-2 and coordinated with connecting plate 3-3 4-1 and with the back-moving spring 3-4-2 being set on lead 3-4-1.
Guiding slide bar 3-2-1 that the straight-line motion mechanism 3-2 includes being arranged in frame 1, it is arranged on and is oriented to slide bar 3- Sliding block 3-2-2 on 2-1 and with sliding block 3-2-2 with merging the ball-screw 3-2-3 that is connected with motor 3-1 output ends.
In the specific implementation, control system initializes, and motor 3-1 reversions, linear motion machine is driven by timing belt Structure 3-2 ball-screw 3-2-3 rotations, and then run up with movable slider 3-2-2 so that connecting plate 3-3 contacts dewclaw sliding block Upper surface in 2-2, then drive upper gripper jaw 2-1 to move upwards, and pass through fixed pulley 3-5, movable pulley 3-6 and steel wire rope 3-7 groups Into link gear move downward lower claw sliding block 4-2, until sliding block 3-2-2 runs to upper limit optocoupler position, motor 3-1 is stalled, and completes system initialization action.
Clamp paper money action:Paper money is placed on lower clamping jaw 4-1, at this moment motor 3-1 is rotated forward, and passes through timing belt band Dynamic straight-line motion mechanism 3-2 ball-screw 3-2-3 rotations, and then run downwards with movable slider 3-2-2 so that connecting plate 3-3 Compression reseting spring 3-4-2, dewclaw sliding block 2-2 and upper gripper jaw 2-1 is driven to move downwardly to contact paper money upper surface, in this mistake Cheng Zhong, due to being that connecting plate 3-3 and dewclaw sliding block 2-2 is synchronously to move downward, steel wire rope 3-7 is fixed on connecting plate 3-3 one end The distance of decline is equal with the distance for being fixed on the decline of the dewclaw sliding block 2-2 other ends, so movable pulley 3-6 is not moved, lower claw is slided Block 4-2 is still in reset state, so that it is guaranteed that only upper gripper jaw 2-1 is moved downward, paper money will not be lifted.
After upper gripper jaw 2-1 contacts paper money upper surface, by the reaction force of paper money, upper gripper jaw 2-1 decrease speed drops It is low, and motor 3-1 rotating speeds keep constant, because dewclaw sliding block 2-2 and connecting plate 3-3 is connected by flexible linking device 3-4 Connect, when upper gripper jaw 2-1 touches paper money, upper gripper jaw 2-1 can be by the reverse tension of paper money, connecting plate 3-3 dropping distance More than upper gripper jaw 2-1 dropping distance, now back-moving spring 3-4-2 is compressed, because steel wire rope 3-7 is that rigidity can not be drawn It is long, so movable pulley 3-6 and lower claw sliding block 4-2 has been pulled upwardly simultaneously so that paper money is elevated, until connecting plate 3-3 with it is upper To a certain degree, triggering is arranged on the optocoupler on dewclaw sliding block 2-2, and sends motor 3-1 to and stop for pawl sliding block 2-2 relative motions The signal turned, must now clamp paper money.
Discharge paper money action:Control system is connected to the signal of release paper money, and motor 3-1 is inverted, connecting plate 3-3 Run up, steel wire rope 3-7 is converted to the trend of relaxed state by tensioned state, due to movable pulley 3-6, dewclaw sliding block 2-2 and Lower clamping jaw 4-1 Action of Gravity Field and back-moving spring 3-4-2 and stage clip 5-1 elastic force effect so that steel wire rope 3-7 stretchings, enter And movable pulley 3-6, dewclaw sliding block 2-2 decline, and then paper money is declined, be put into the plane specified up.Connecting plate 3-3 with it is upper When upper surface contacts in pawl sliding block 2-2, upper gripper jaw 2-1 has been detached from paper money, the steel wire rope 3-7 being now connected on connecting plate 3-3 The distance that one end is up moved is equal with being connected in the distance that dewclaw sliding block 2-2 steel wire rope 3-7 one end is up moved, and at this moment moves and slides Wheel 3-6 and lower claw sliding block 4-2 is not moved.
Said process is the single course of work paper money of gripping, and the paper money gripped in actual motion is divided into two kinds of shapes Formula:For a kind of list for being ten stackings paper money, another kind is that ten money tied up have been tied.
The first, ten the single paper money of a stacking, and because of the difference of its fluffy degree, the height difference after stacking is larger. For this kind of paper money, it is not necessary to which for folder into incompressible state, somewhat clamp that some can meet not topple in moving process will Ask.Upper gripper jaw 2-1 first contacts paper money, is pressed downward after certain distance, under upper gripper jaw 2-1 is just caused by the opposition of money handle Reduction of speed degree reduces, and the speed for the connecting plate 3-3 that motor 3-1 drives is constant, begins to compression reseting spring 3-4-2, Lower clamping jaw 4-1 is lifted simultaneously, now back-moving spring 3-4-2 and paper money all bi-directional compressions, until connecting plate 3-3 and dewclaw sliding block 2- The distance that 2 relative motions are fixed, to ensure that money bundle is compacted.If set connecting plate 3-3 and dewclaw sliding block 2-2 relative motions away from From L, then it is believed that lower clamping jaw 4-1 has also moved about L distance upwards.
Second, ten tied up money bundle.During tying up, the pressure that cross strapper is applied to paper money is non- Chang great, it can thus be assumed that ten money bundles tied up are to recompress.When gripping incompressible money bundle, Ye Shishang Clamping jaw 2-1 first contacts paper money, because of its Incoercibility, it is believed that upper gripper jaw 2-1 is no longer moved downward, and connecting plate 3-3 continue to Under, will compression reseting spring 3-4-2, while lift lower clamping jaw 4-1, it itself is incompressible rigid body that now money, which is tied, institute It is bi-directional compression with back-moving spring 3-4-2, lower clamping jaw 4-1 and upper gripper jaw 2-1 are lifted up identical distance, until connecting plate 3-3 and dewclaw sliding block 2-2 relative motions cause upper limit optocoupler to be triggered.It can finally think that connecting plate 3-3 and dewclaw are slided roughly Block 2-2 relative motions L/2 distance, lower clamping jaw 4-1 have also run up L/2 distance.In addition, during no-load running, point Not top lower limit optocoupler carries out the control of motor positive and inverse signal.
