In specific implementation, the control system is initialized, the driving motor 3-1 is reversed, the ball screw 3-2-3 of the linear motion mechanism 3-2 is driven to rotate through the synchronous belt, the sliding block 3-2-2 is driven to move upwards, the connecting plate 3-3 is enabled to contact the upper end face in the upper claw sliding block 2-2, then the upper clamping jaw 2-1 is driven to move upwards until the sliding block 3-2-2 moves to an upper limiting optocoupler position, the driving motor 3-1 is stopped, and the system initialization is completed. In the process, the ratchet wheel 3-5-1 and the brake rod 3-5-2 are in a separated state, the gear 3-6-1 performs pure rolling motion on the rack 3-6-2, the lower claw sliding block 4-2 is reset under the action of the reset spring 3-4-2, and the lower claw sliding block is arranged on the upper rack 3-6-2 of the sliding rail and is kept at the highest position through the leverage of the lever 3-6-3.
The action of clamping the banknote handles: the banknote handle is placed on the lower clamping jaw 4-1, at the moment, the driving motor 3-1 rotates positively, the ball screw 3-2-3 of the linear motion mechanism 3-2 is driven to rotate through the synchronous belt, the sliding block 3-2-2 is driven to move downwards, the connecting plate 3-3 compresses the reset spring 3-4-2, the upper jaw sliding block 2-2 and the upper clamping jaw 2-1 are driven to move downwards until the upper end face of the banknote handle is contacted, at the moment, the ratchet wheel 3-5-1 and the brake rod 3-5-2 are in a separated state, the gear 3-6-1 performs pure rolling motion on the rack 3-6-2, and the lower jaw sliding block 4-2 is still in a reset state.
After the upper clamping jaw 2-1 contacts the upper end face of the banknote receiving handle, the descending speed of the upper clamping jaw 2-1 is reduced, the rotating speed of the driving motor 3-1 is kept unchanged, so that the connecting plate 3-3 and the upper jaw sliding block 2-2 start to move relatively, the triggering rod 3-5-4 jacks up the rotating rod 3-5-3 to rotate, the braking rod 3-5-2 rotates anticlockwise to contact with the ratchet wheel 3-5-1 against the acting force of the tension spring 3-5, the gear 3-6-1 does not roll purely any more, the rack 3-6-2 is driven to move downwards under the action of the meshing teeth, one end of the lever 3-6-3 is pressed, and the other end of the lever 3-6-3 is pressed upwards to prop up the lower jaw sliding block 4-2. The upper clamping jaw 2-1 moves downwards until the connecting plate 3-3 and the upper jaw sliding block 2-2 move relatively to a certain extent, an optical coupler arranged on the upper jaw sliding block 2-2 is triggered, and a signal for stopping the driving motor 3-1 is transmitted, so that a banknote handle is clamped necessarily;
the action of releasing the banknote handles: the control system receives a signal for releasing the banknote handles, the driving motor 3-1 reverses, the connecting plate 3-3 moves upwards, the reset spring 3-4-2 is reset gradually, the trigger rod 3-5-4 and the rotating rod 3-5-3 are separated gradually, the brake rod 3-5-2 is driven to separate from the ratchet wheel 3-5-1, the gear 3-6-1 also recovers to do pure rolling motion on the rack 3-6-2, the lower claw sliding block 4-2 drives the lower clamping jaw 4-1 to reset under the action of the reset spring 3-6-4, and one end of the lever 3-6-3 is supported at the same time so that the other end of the lever 3-6-3 supports the rack 3-6-2 upwards. After the connecting plate 3-3 moves upwards to contact with the upper end surface in the upper claw sliding block 2-2, the upper clamping claw 2-1 is driven to move upwards until the upper limiting optocoupler is triggered, and the driving motor 3-1 is controlled to stop rotating.
The process is a working process of clamping a single banknote bundle, and the banknote bundle clamped in actual operation is divided into two forms: one is ten single banknote handles stacked one by one, and the other is ten bundled banknote bundles.
First, ten single banknote handles of a pile up neatly, because of its fluffy degree difference, the difference in height behind the pile up neatly is great. For the banknote handles, the banknote handles are not required to be clamped in an incompressible state, and the banknote handles can be slightly clamped to meet the requirement of not toppling in the moving process. After the upper clamping jaw 2-1 contacts the banknote handle and is pressed downwards for a certain distance, the upper clamping jaw 2-1 receives the reverse acting force of the banknote handle to reduce the descending speed, the speed of the connecting plate 3-3 driven by the driving motor 3-1 is unchanged, the reset spring 3-4-2 starts to be compressed, the lower clamping jaw 4-1 is lifted, and at the moment, the reset spring 3-4-2 and the banknote handle are pressed in two directions until the connecting plate 3-3 and the upper jaw sliding block 2-2 move relatively for a fixed distance, so that the banknote bundle is ensured to be pressed. If the relative movement distance L between the connecting plate 3-3 and the upper jaw slider 2-2 is set, the lower jaw 4-1 can be considered to be moved upward by a distance L/2-L.
Second, ten bundles of bundled money have been made. During the strapping process, the cross strapping machine applies a very high pressure to the handles of money, and therefore ten bundles of money that have been strapped are considered incompressible. When an incompressible money bundle is clamped, the upper clamping jaw 2-1 is firstly contacted with the money bundle, the upper clamping jaw 2-1 is considered to be not moved downwards due to incompressibility, the connecting plate 3-3 is further downwards, the reset spring 3-4-2 is compressed, the lower clamping jaw 4-1 is lifted, at the moment, the money bundle is an incompressible rigid body, the reset spring 3-4-2 is compressed in two directions, and the lower clamping jaw 4-1 and the upper clamping jaw 2-1 are lifted upwards by the same distance until the upper limiting optocoupler is triggered by the relative movement of the connecting plate 3-3 and the upper clamping jaw slider 2-2. Finally, it can be roughly assumed that the connecting plate 3-3 and the upper jaw slider 2-2 move relatively by a distance of L/2, and the lower jaw 4-1 also moves upward by a distance of L/2. In addition, during no-load operation, the motor forward and reverse rotation signals are controlled by the upper and lower limiting optocouplers respectively.
