In the deposit position, the bundle of banknotes is placed on the turnover plate 212 placed horizontally, adjacent to the carriage 211.
After the gripper mechanism 125 places the pre-bundled products (e.g., bundles of banknotes) in the bundling machine in the banknote deposit position, the flipping plate 212 and the carriage 211, which are disposed orthogonal to each other, are rotated 90 degrees to a banknote raising position following the flipping shaft 22. The banknote lifting position is used for preparing to lift the banknote bundle, and at this time, the bracket 211 is folded with the lifting plate 271, so that the turned banknote bundle also falls on the lifting plate 211. The turnover plate 212 is directed upwards to enclose the turned banknote bundle and prevent the banknote bundle from sliding off.
As shown in fig. 7A, the lifting plate 271 includes a recess that accommodates the folded bracket 211 and forms an approximate plane. The recess is completely opened adjacent to one side of the inversion shaft 22 so that the bracket 211 does not interfere with the lifting plate 271 to freely slide up and down. The lifting plate 271 is provided with a distal end adjacent to the reversing shaft 22 to ensure that all of the banknote bundles can be accommodated. In a preferred embodiment, the end of the lifting plate 271 further comprises at least one banknote blocking plate (not shown) which is arranged parallel to and against the turning shaft 22, also ensuring that all the banknote bundles can be accommodated. Therefore, after the lifting plate 271 with the bundle thereon is lifted beyond the height of the upright turn plate 212, the bundle after turning can be prevented from slipping down.
The turnover driving mechanism comprises a first cylinder 24 connected with and driving a driving group, the first cylinder 24 is fixed on a first cylinder mounting plate 25, the first cylinder mounting plate 25 is fixed relative to the back plate 23, i.e. fixed relative to the turnover driving mechanism, i.e. the first cylinder mounting plate 25 can be directly and fixedly connected with the back plate 23 or fixedly connected to other fixing parts of the turnover driving mechanism, so long as the position is kept fixed. The driving set includes a swing link 240 connected to the piston end of the first cylinder 24, where one end of the swing link 240 reciprocates along with the piston end of the first cylinder 24, so as to drive the other end of the swing link 240 to rotate. The other end of the swing rod 240 is fixedly connected with the turning shaft 22, and the turning shaft 22 is fixedly connected with a fixing component of the turning driving mechanism, such as the rear baffle 23, through at least one bearing. The bearings are preferably provided at both ends of the tilting shaft 22 so that the tilting shaft 22 can freely rotate about its central long axis without translating with respect to the fixed part of the tilting drive mechanism while maintaining the position of the tilting shaft 22.
When the turnover device is turned over, the piston end of the first cylinder 24 stretches and contracts to drive the swing rod 240 to reciprocate, so that the other end of the swing rod 240 drives the turnover shaft 22 to rotate around the axis of the turnover shaft 22, and the turnover plate 212 and the bracket 211 fixedly arranged on the turnover shaft 22 are driven to turn over back and forth.
In a preferred embodiment of the present invention, the tilting and lifting mechanism 20 further includes a bottom plate 220, the bottom plate 220 is horizontally disposed and is vertically fixed to the rear baffle 23, at this time, the lifting plate 271, the tilting plate 212 and the bracket 211 are all located on the upper side of the bottom plate 220, and the first cylinder mounting plate 25 and the bearing are fixedly mounted on the lower side of the bottom plate 220.

A sliding seat 1244 is arranged below the synchronous belt 1247, a sliding rail 1243 is arranged at the bottom of the installation frame 124000, and the sliding seat 1244 can slide along the sliding rail 1243 under the driving of the synchronous wheel 1246. The two ends of the sliding rail 1243 are respectively provided with an optocoupler 1245 for detecting whether the sliding block 1244 moves to a preset maximum distance, and the control system operates the pushing mechanism to drive the motor 1240 to work through detection information so as to enable the synchronous wheel 1246, the synchronous belt 1247 and the sliding block 1244 to move back and forth.
The bottom of the mounting bracket 124000 is provided with a window along the sliding rail 1243, and the push rod 1241 is connected to the slide mount 1244 through the window so as to reciprocate with the slide mount 1244. The free end of the push rod 1241 is mounted with a push plate 1242.
When the overturning and pushing mechanism 20 pushes the pre-bundled product (such as a banknote bundle) to a predetermined position, the pushing mechanism driving motor 1240 drives the synchronizing wheel 1246 to rotate in a first direction, so as to drive the sliding seat 1244 to drive the pushing plate 1242 to move forward, and push the pre-bundled product to the conveying flat plate 12 for a subsequent procedure, when the optocoupler 1245 detects that the sliding seat 1244 moves to a maximum distance, the overturning and pushing mechanism 20 drives the synchronizing wheel to rotate reversely, and the pushing plate 1242 is returned to an initial position to be pushed for a subsequent pre-bundled product.
As shown in fig. 9, the conveying 12 plate includes a supporting member 121, a conveying plate 122 fixed on the supporting member 121, and a movable plate 123 provided at an edge of the conveying plate 122, the movable plate 123 being rotatable or tiltable downward around the edge of the conveying plate 122.
