Detailed implementation manners

[0057] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments and features in the embodiments of this application can be combined arbitrarily with each other.

[0058] Embodiment 1

[0059] The banknote bundling machine provided by the embodiment of the present invention is as Figures 1 to 8As shown, it includes a pressing mechanism 100, a pressure relief mechanism 200, a paper tape pre-pressing mechanism 300, and a heat-sealing mechanism 400. The pressure relief mechanism 200 is located below the pressing mechanism 100. The paper tape pre-pressing mechanism 300 is located on one side of the pressure relief mechanism 200, and the heat-sealing mechanism 400 is located on the other side of the pressure relief mechanism 200. The pressing mechanism 100 presses down to hold the stack of banknotes 10 placed on the pressure relief mechanism 200. The middle part of the paper tape 20 is pressed between the stack of banknotes 10 and the pressure relief mechanism 200. The first extended end 21 of the paper tape 20 is located on one side of the pressure relief mechanism 200, and the second extended end 22 is located on the other side of the pressure relief mechanism 200. The paper tape pre-pressing mechanism 300 is used to fold and press the first extended end 21 on the top surface of the stack of banknotes 10. The heat-sealing mechanism 400 is used to fold and heat-seal the second extended end 22 to the first extended end 21 to complete the bundling of the stack of banknotes 10. The pressure relief mechanism 200 presses down to relieve the pressure on the bundled stack of banknotes 10, so that the bundled stack of banknotes 10 can be removed.

[0060] For this banknote stack bundling machine, the paper tape 20 is first placed on the pressure relief mechanism 200. The first extended end 21 of the paper tape 20 is located on one side of the pressure relief mechanism 200, and the second extended end 22 is located on the other side of the pressure relief mechanism 200. Then the stack of banknotes 10 is placed on the pressure relief mechanism 200 and holds the paper tape 20. Then the pressing mechanism 100 presses down to hold the stack of banknotes 10 on the pressure relief mechanism 200. The paper tape pre-pressing mechanism 300 then folds and presses the first extended end 21 on the top surface of the stack of banknotes 10. The heat-sealing mechanism 400 then folds and heat-seals the second extended end 22 to the first extended end 21 to complete the bundling of the stack of banknotes 10. In this way, the bundling effect of the stack of banknotes 10 is good. When it is necessary to remove the bundled stack of banknotes 10, the pressure relief mechanism 200 presses down to relieve the pressure on the bundled stack of banknotes 10 and release the stack of banknotes 10. At this time, the bundled stack of banknotes 10 can be removed between the pressing mechanism 100 and the pressure relief mechanism 200, and the user experience of the manufactured banknote stack bundling machine is better.

[0061] Exemplarily, as Figure 9 shown, the banknote stack bundling machine further includes: a pushing mechanism 500, located at the rear side of the pressure relief mechanism 200, for pushing the bundled stack of banknotes 10 after pressure relief forward to remove the bundled stack of banknotes 10 in an automatic manner, which can further improve the user experience.

[0062] As Figure 2As shown, the pressing mechanism 100 includes: a first driving member 110; a mounting plate 120, located below the first driving member 110 and mounted on the first driving member 110; and pressing blocks 130 arranged front and rear, protruding on the lower plate surface of the mounting plate 120. The pressing mechanism 100 further includes a fourth frame plate 140, a guide rod 150 and a connecting member 160. The first driving member 110 is fixed on the fourth frame plate 140. The guide rod 150 is movably inserted through the fourth frame plate 140. The connecting member 160 is fixed to the lower end of the first driving member 110 and the lower end of the guide rod 150. The mounting plate 120 is located below the connecting member 160. The middle part of the mounting plate 120 and the middle part of the connecting member 160 are connected by a vertically arranged connecting column. The first driving member 110 can be configured as a cylinder.

[0063] As Figure 3 shown, the pressure relief mechanism 200 includes: a first frame plate 210; a second driving member 220, mounted on the first frame plate 210; a limiting plate 230, located above the first frame plate 210 and mounted on the second driving member 220; a guide rail column 240, movably inserted through the first frame plate 210 and the limiting plate 230 up and down; a supporting plate 250, located above the limiting plate 230 and fixed to the upper end of the guide rail column 240. The upper surface of the supporting plate 250 is a concave curved surface. The paper tape 20 and the banknote bundle 10 are located on the concave curved surface; and a first elastic member 260, sleeved on the guide rail column 240 and supported between the limiting plate 230 and the supporting plate 250. The second driving member 220 can be configured as a cylinder, and the first elastic member 260 can be configured as a helical spring. A top column 231 is provided on the top surface of the limiting plate 230.

[0064] Among them, the first driving member 110 drives the mounting plate 120 and the pressing block 130 to move downward together, so that the supporting plate 250 is pressed downward from the first position to the second position. The lower surface of the supporting plate 250 presses on the top post 231. At this time, the pressing block 130 presses the banknote bundle 10 on the concave curved surface. The middle parts of the banknote bundle 10 and the paper tape 20 both bend downward along the concave curved surface. The two sides of the banknote bundle 10, the first extending end 21 and the second extending end 22 all tilt upward along the concave curved surface. In this way, the paper tape pre-pressing mechanism 300 can more smoothly fold and press the first extending end 21 on the upper plate surface of the mounting plate 120, and the heat-sealing mechanism 400 can also more smoothly fold and heat-seal the second extending end 22 to the first extending end 21. The first extending end 21 and the second extending end 22 are heat-sealed and bonded on the upper plate surface of the mounting plate 120, preventing the heat-sealing mechanism 400 from scalding the uppermost banknotes of the banknote bundle 10. Moreover, since the banknote bundle 10 is tied in a bent state, the paper tape 20 can tie the banknote bundle 10 more tightly. The second driving member 220 drives the limiting plate 230 to move downward to relieve pressure. The supporting plate 250 moves downward from the second position to the third position. The banknote bundle 10 is released between the supporting plate 250 and the mounting plate 120, and the banknote bundle 10 is suspended at the front end of the mounting plate 120 through the heat-sealed and bonded paper tape 20.

[0065] As Figure 3 and Figure 9 shown, the pushing mechanism 500 includes: a third driving member 510; and a pushing member 520 mounted on the third driving member 510. A push rod 530 is erected on the pushing member 520, and a matching long hole 251 is provided on the supporting plate 250.

[0066] Among them, when the supporting plate 250 is in the first position, the push rod 530 is located below the matching long hole 251; when the supporting plate 250 moves downward to the second position, the push rod 530 passes through the matching long hole 251 and extends upward; when the supporting plate 250 moves downward to the third position, at this time the banknote bundle 10 is relieved of pressure and in a releasable state, the third driving member 510 pushes the pushing member 520 forward, the push rod 530 pushes the banknote bundle 10 forward, and the banknote bundle 10 is pushed forward between the mounting plate 120 and the supporting plate 250.

[0067] As Figure 4 and Figure 5 shown, the paper tape pre-pressing mechanism 300 includes: a second frame plate 310; a fourth driving member 320 mounted on the second frame plate 310; and a top pressing member 330 mounted on the fourth driving member 320. At this time, the fourth driving member 320 drives the top pressing member 330 to move obliquely downward toward the top surface of the banknote bundle 10, and can fold and press the first extending end 21 of the paper tape 20 on the top surface of the banknote bundle 10. The fourth driving member 320 can be configured as a cylinder.

[0068] As Figure 4 and Figure 5As shown, the paper tape pre-pressing mechanism 300 may further include: a side pressing member 340, located below the top pressing member 330 and hinged to the second frame plate 310 at its lower end; a rope 350, one end connected to the top pressing member 330 and the other end connected to the side pressing member 340; and a second elastic member 360, disposed between the side pressing member 340 and the second frame plate 310 and below the rope 350, for tightening the rope 350 between the top pressing member 330 and the side pressing member 340. At this time, the fourth driving member 320 drives the top pressing member 330 to move obliquely downward toward the top surface of the banknote bundle 10, the rope 350 is released, and the top of the side pressing member 340 swings toward the side surface of the banknote bundle 10 under the action of the second elastic member 360 to press a part of the first extended end 21 against one side surface of the banknote bundle 10, flattening the paper tape 20 on this side surface of the banknote bundle 10. Subsequently, the top pressing member 330 folds and presses the other part of the first extended end 21 against the upper plate surface of the mounting plate 120. After the paper tape 20 is heat-sealed and bonded, the banknote bundle 10 can be tied more tightly. To eliminate the interference of the supporting plate 250 with the pressing action of the side pressing member 340, a notch 252 for the side pressing member 340 to pass through is provided on one side of the supporting plate 250 facing the side pressing member 340. The second elastic member 360 may be configured as a torsion spring.

[0069] As Figures 6 to 8 shown, the heat-sealing mechanism 400 includes a third frame plate 410, a fifth driving member 420, a connecting rod 430, and a heat-sealing knife 440. The fifth driving member 420 and the connecting rod 430 are both hinged to the third frame plate 410 and form a four-bar linkage 430. The heat-sealing knife 440 is mounted on the four-bar linkage 430. The fifth driving member 420 may be configured as a cylinder. When the fifth driving member 420 extends, the four-bar linkage 430 drives the heat-sealing knife 440 to perform a curvilinear movement toward the top surface of the banknote bundle 10, pushing the second extended end 22 downward to fold it, so as to fold and heat-seal the second extended end 22 to the first extended end 21. After the heat-sealing and bonding is completed, the fifth driving member 420 retracts, and the four-bar linkage 430 drives the heat-sealing knife 440 to reset. The lower part of the heat-sealing knife 440 has a heat-sealing working surface 441.

[0070] The process of tying the banknote bundle with this banknote bundle tying machine is as follows:

[0071] The paper tape 20 is first placed on the supporting plate 250. The first extended end 21 of the paper tape 20 is located on one side of the supporting plate 250, and the second extended end 22 is located on the other side of the supporting plate 250. Then, the stack of banknotes 10 is placed on the supporting plate 250 and presses the middle part of the paper tape 20. The first driving member 110 drives the mounting plate 120 and the pressing block 130 to move downward together, so that the supporting plate 250 moves downward from the first position to the second position. The pressing block 130 presses the stack of banknotes 10 on the concave curved surface. At this time, the push rod 530 extends upward through the matching long hole 251. The middle parts of the stack of banknotes 10 and the paper tape 20 both bend downward along the concave curved surface, and both sides of the stack of banknotes 10, the first extended end 21 and the second extended end 22 all tilt upward along the concave curved surface. The fourth driving member 320 drives the top pressing member 330 to move obliquely downward toward the top surface of the stack of banknotes 10, and the rope 350 is released. Under the action of the second elastic member 360, the top of the side pressing member 340 swings toward the side surface of the stack of banknotes 10, and a part of the first extended end 21 is preferentially pressed on one side surface of the stack of banknotes 10. On this side surface of the stack of banknotes 10, the paper tape 20 is flattened. Then, the top pressing member 330 folds and presses the other part of the first extended end 21 on the upper plate surface of the mounting plate 120. The fifth driving member 420 extends, and the four-link mechanism 430 drives the heat-sealing knife 440 to perform a curved movement toward the top surface of the stack of banknotes 10, pushing the second extended end 22 to fold downward, so as to fold and heat-seal the second extended end 22 to the first extended end 21. After the heat-sealing is completed: the fifth driving member 420 retracts, and the four-link mechanism 430 drives the heat-sealing knife 440 to reset; the fourth driving member 320 retracts, and the top pressing member 330 and the side pressing member 340 reset, and the rope 350 is tightened again. The second driving member 220 drives the limiting plate 230 to move downward to relieve pressure, and the supporting plate 250 moves downward from the second position to the third position. The stack of banknotes 10 is released between the supporting plate 250 and the mounting plate 120 and is suspended on the mounting plate 120 through the heat-sealed paper tape 20. The third driving member 510 pushes the pushing member 520 forward, and the push rod 530 pushes the stack of banknotes 10 forward. The stack of banknotes 10 is pushed out between the mounting plate 120 and the supporting plate 250. After the stack of banknotes 10 is pushed out: the third driving member 510 drives the pushing member 520 to drive the push rod 530 to reset, and the first driving member 110 drives the mounting plate 120 and the pressing block 130 to reset.

[0072] Embodiment 2

[0073] The difference between this embodiment and Embodiment 1 is that, as Figures 10 to 19 shown, the banknote bundling machine further includes: a paper tape supply mechanism 600, arranged above one side of the pressure relief mechanism 200, for automatically supplying a paper tape 20 of a set length to the pressure relief mechanism 200; and a banknote supply mechanism, arranged at the rear side of the pressure relief mechanism 200, for supplying the stack of banknotes 10 to the pressure relief mechanism 200.

[0074] As Figure 20As shown, the paper tape supply mechanism 600 includes a paper tape supply component 610, an inkjet printing component 620, and a vertically arranged cutting component 630. The paper tape supply component 610 is used to supply the paper tape 20 from the paper tape roll. The inkjet printing component 620 is used to print the bundling information on the supplied paper tape 20. The cutting component 630 is used to cut off a set length of the paper tape 20. The bundling information is printed on each paper tape 20 of the set length.

[0075] As Figures 10 to 12 shown, the banknote bundle supply mechanism includes a banknote bundle storage bin 700, a banknote supporting component 800, and a banknote pushing component 900. The banknote bundling machine further includes a banknote sorting component 1000. The banknote sorting component 1000 is located above the other side of the pressure relief mechanism 200, that is, the banknote sorting component 1000 and the paper tape supply mechanism 600 are on both sides of the pressure relief mechanism 200. The banknote supporting component 800 is located below the banknote bundle storage bin 700. The pushing mechanism 500 is located below the banknote supporting component 800. The banknote pushing component 900 is located at the rear side of the banknote bundle storage bin 700. The banknote supporting component 800 can move forward to the fourth position and move backward to the fifth position. The fourth position is located above the supporting plate 250. The banknote bundle storage bin 700 is used to store the banknote bundles 10. The banknote sorting component 1000 is used to sort the banknote bundles 10 on the banknote supporting component 800 at the fourth position.

[0076] When the banknote supporting component 800 moves forward to the fourth position, the banknote pushing component 900 pushes the banknote bundle 10 forward, so that the banknote bundle 10 falls forward onto the banknote supporting component 800. Then, the banknote sorting component 1000 sorts the banknote bundles 10 on the banknote supporting component 800. After the sorting is completed, the banknote sorting component 1000 resets (during the sorting process, the paper tape supply mechanism 600 extends the end of the paper tape roll into the gap between the banknote supporting component 800 and the supporting plate 250, and cuts a set length through the cutting component 630, so that the cut paper tape 20 of the set length falls onto the supporting plate 250). Then, the banknote supporting component 800 moves backward to the fifth position, and the banknote bundle 10 on the banknote supporting component 800 is blocked by the banknote pushing component 900 and falls onto the supporting plate 250 and presses on the middle of the paper tape 20 of the set length.

[0077] As Figure 13 and Figure 14As shown, the banknote pushing assembly 900 includes: a fifth mounting plate 910 having a front vertical plate 911, a rear vertical plate 912, and connecting side plates; an eighth driving member 920 fixed to the rear vertical plate 912; a lead screw 930 rotatably mounted between the front vertical plate 911 and the rear vertical plate 912 and drivingly engaged with the eighth driving member 920 through a pulley structure; a nut block 940 mounted on the lead screw 930; a second guide rod 950 arranged parallel to the lead screw 930, the front end of the second guide rod 950 passing through the front vertical plate 911 and protruding forward, and the rear end fixed to the nut block 940; and a push plate 960 fixed to the front end of the second guide rod 950. A tongue piece 30 protrudes forward from the lower end of the push plate 960. A long groove 40 is arranged in the front-rear direction on the bottom surface of the banknote bundle storage bin 700. The tongue piece 30 sinks downward into the long groove 40, and the tongue piece 30 is located below the banknote bundle 10 in the banknote bundle storage bin 700, ensuring that the lowest layer of banknotes is not missed during the process of the push plate 960 pushing the banknote bundle 10. The eighth driving member 920 can be configured as a motor.

[0078] As Figure 15 and Figure 16 As shown, the banknote supporting assembly 800 includes: a seventh driving member 810; and a banknote supporting plate 820 mounted on the seventh driving member 810. The seventh driving member 810 is used to drive the banknote supporting plate 820 to move forward to the fourth position and move backward to the fifth position. A guide post 830 is arranged beside the banknote supporting mechanism 800. The banknote supporting plate 820 cooperates with the guide post 830, and the guide post 830 guides the movement stroke of the banknote supporting plate 820 in the front-rear direction.

[0079] As Figures 17 to 19 As shown, the banknote sorting assembly 1000 includes: a sixth driving member 1100; and a banknote sorting plate 1200 hingedly mounted on the sixth driving member 1100. A third elastic member 1300 is arranged between the banknote sorting plate 1200 and the sixth driving member 1100. On the other side of the pressure relief mechanism 200, there is a mounting vertical plate 2000. The sixth driving member 1100 pushes the banknote sorting plate 1200 to move towards the mounting vertical plate 2000. The banknote bundle 10 on the banknote supporting assembly 800 is sorted by the banknote sorting plate 1200 and the mounting vertical plate 2000. This structure can be applicable to banknotes of different widths. A second tongue piece 31 is arranged at the lower end of the banknote sorting plate 1200, and a second long groove 41 is arranged at the end of the banknote supporting plate 820, which can also ensure that the lowest layer of banknotes is not missed during the banknote sorting process. The third elastic member 1300 can be configured as a torsion spring.

[0080] The operation processes of the paper tape supply mechanism 600 and the banknote bundle supply mechanism are as follows:

[0081] There are banknote bundles 10 placed in the banknote bundle storage bin 700. The seventh driving member 810 drives the banknote supporting plate 820 to move forward to the fourth position. The eighth driving member 920 drives the pushing plate 960 to move forward, pushing the banknote bundle 10 in the banknote bundle storage bin 700 forward onto the banknote supporting plate 820. The sixth driving member 1100 drives the banknote aligning plate 1200 to move towards the mounting vertical plate 2000, and the second tongue 31 sinks into the second long groove 41, pressing the banknote bundle 10 on the banknote supporting plate 820 against the side of the mounting vertical plate 2000 for banknote alignment. The paper tape supply mechanism 600 supplies a set length of paper tape 20 onto the paper tape supporting plate 250 through the gap between the banknote supporting plate 820 and the paper tape supporting plate 250. After the banknote alignment operation is completed: The sixth driving member 1100 drives the banknote aligning plate 1200 to reset. The seventh driving member 810 drives the banknote supporting plate 820 to move backward to the fifth position, and the banknote bundle 10 on the banknote supporting plate 820 drops onto the paper tape supporting plate 250 due to the blockage of the pushing plate 960. At this time, the middle part of the paper tape 20 is pressed between the banknote bundle 10 and the paper tape supporting plate 250, and then the eighth driving member 920 drives the pushing plate 960 to reset.

[0082] Embodiment III

[0083] The control method of the banknote bundle strapping machine provided by the embodiment of the present invention (not shown in the figure) includes:

[0084] Place the paper tape 20 and the banknote bundle 10 on the pressure relief mechanism 200. The first protruding end 21 is located on one side of the pressure relief mechanism 200, and the second protruding end 22 is located on the other side of the pressure relief mechanism 200. The banknote bundle 10 is pressed against the middle part of the paper tape 20;

[0085] Drive the pressing mechanism 100 to move downward so that the pressing mechanism 100 presses the banknote bundle 10 placed on the pressure relief mechanism 200;

[0086] Drive the paper tape pre-pressing mechanism 300 to fold and press the first protruding end 21 on the top surface of the banknote bundle 10;

[0087] Drive the heat-sealing mechanism 400 to fold and heat-seal and bond the second protruding end 22 to the first protruding end 21 to complete the strapping of the banknote bundle 10;

[0088] Drive the pressure relief mechanism 200 to move downward to relieve the pressure on the strapped banknote bundle 10 so that the strapped banknote bundle 10 can be removed (see Figure 1 for understanding).

[0089] For the control method of this banknote bundle strapping machine, the strapping effect of the banknote bundle 10 is good, which can improve the user experience of using the banknote bundle strapping machine.

[0090] For example, the step of driving the pressing mechanism 100 to move downward so that the pressing mechanism 100 presses the banknote handle 10 placed on the pressure relief mechanism 200 includes: driving the mounting plate 120 and the pressing block 130 to move downward by the first driving member 110, so that the pressing block 130 presses the banknote handle 10 on the concave surface of the supporting plate 250, and presses the supporting plate 250 from the first position to the second position, the middle part of the banknote handle 10 and the middle part of the paper tape 20 are bent downward along the concave surface, and the two sides of the banknote handle 10, the first protruding end 21 and the second protruding end 22 are tilted upward along the concave surface (see Figures 1 to 3 to understand).

[0091] In this way, the paper tape pre-pressing mechanism 300 can more smoothly fold the first extension end 21 and press it on the top surface of the banknote handle 10, and the heat-sealing mechanism 400 can more smoothly fold the second extension end 22 and heat-seal it to the first extension end 21. In addition, since the banknote handle 10 is tied in a bent state, the paper tape 20 can tie the banknote handle 10 more tightly.

[0092] For example, the step of driving the paper tape pre-pressing mechanism 300 to fold and press the first protruding end 21 on the top surface of the banknote handle 10 includes: driving the top pressing member 330 to move obliquely downward toward the top surface of the banknote handle 10 through the fourth driving member 320, the rope 350 is released, and the side pressing member 340 is swung toward the side of the banknote handle 10 at the top under the action of the second elastic member 360, and a part of the first protruding end 21 is preferentially pressed and adhered to one side surface of the banknote handle 10, and the paper tape 20 on the side is flattened, and the top pressing member 330 folds and presses another part of the first protruding end 21 on the upper plate surface of the mounting plate 120 with a delay, and the first protruding end 21 and the second protruding end 22 are heat-sealed and bonded on the upper plate surface of the mounting plate 120, which can prevent the heat-sealing mechanism 400 from scalding the topmost banknote of the banknote handle 10 (see Figure 1 , Figure 4 and Figure 5 to understand).

[0093] For example, the step of driving the heat-sealing mechanism 400 to fold the second extension end 22 and heat-seal it to the first extension end 21 to complete the binding of the banknote handle 10 includes: driving the fifth driving member 420, controlling the heat-sealing knife 440 to move in a curve toward the top surface of the banknote handle 10 through the four-link 430, folding the second extension end 22 and pressing it on the upper plate surface of the mounting plate 120, and heat-sealing it with the first extension end 21 on the upper plate surface of the mounting plate 120. During heat-sealing, the lower side of the second extension end 22 is bonded to the upper side of the first extension end 21 (see Figure 1 , Figures 6 to 8 to understand).

[0094] Exemplarily, the steps of driving the pressure relief mechanism 200 to move downward to relieve the pressure on the bundled banknote stack 10 so that the bundled banknote stack 10 can be removed include: driving the limit plate 230 to move downward through the second driving member 220, so that the supporting plate 250 moves downward from the second position to the third position to relieve the pressure on the bundled banknote stack 10, so as to enable the bundled banknote stack 10 to be removed. When the supporting plate 250 is in the second position, the push rod 530 extends upward through the mating long hole 251 (see Figures 1 to 3 for understanding).

[0095] In an exemplary embodiment, before the steps of placing the paper tape 20 and the banknote stack 10 on the pressure relief mechanism 200, with the first extended end 21 on one side of the pressure relief mechanism 200 and the second extended end 22 on the other side of the pressure relief mechanism 200, and the banknote stack 10 being pressed against the middle of the paper tape 20, the control method further includes: driving the paper tape supply mechanism 600 to supply a set length of the paper tape 20 to the supporting plate 250, so that the middle of the paper tape 20 is supported on the pressure relief mechanism 200, the first extended end 21 is on one side of the pressure relief mechanism 200, and the second extended end 22 is on the other side of the pressure relief mechanism 200 (see Figure 1 , Figures 10 to 12 , Figure 20 for understanding).

[0096] In an exemplary embodiment, before the steps of placing the paper tape 20 and the banknote stack 10 on the pressure relief mechanism 200, with the first extended end 21 on one side of the pressure relief mechanism 200 and the second extended end 22 on the other side of the pressure relief mechanism 200, and the banknote stack 10 being pressed against the middle of the paper tape 20, the control method further includes: driving the banknote stack supply mechanism to supply the banknote stack 10 to the pressure relief mechanism 200 (see Figures 10 to 19 for understanding).

[0097] Exemplarily, the steps of driving the banknote stack supply mechanism to supply the banknote stack 10 to the pressure relief mechanism 200 include: driving the banknote supporting plate 820 to move forward to the fourth position through the seventh driving member 810, the banknote pushing assembly 900 pushing the banknote stack 10 placed in the banknote stack storage bin 700 forward to fall onto the banknote supporting plate 820, driving the banknote aligning plate 1200 to move towards the mounting vertical plate 2000 through the sixth driving member 1100 to align the banknote stack 10 pushed onto the banknote supporting plate 820, after the alignment is completed, the sixth driving member 1100 driving the banknote supporting plate 820 to reset, driving the banknote supporting plate 820 to move backward to the fifth position through the seventh driving member 810, the aligned banknote stack 10 on the banknote supporting plate 820 being blocked by the banknote pushing assembly 900 and falling onto the supporting plate 250, and then driving the banknote pushing assembly 900 to reset (see Figures 10 to 19 for understanding).

[0098] In an exemplary embodiment, after the step of driving the pressure relief mechanism 200 to move downward to relieve the pressure on the bundled banknote stack 10 so that the bundled banknote stack 10 can be removed, the control method further includes: driving the pusher 520 to move forward by the third driving member 510, the push rod 530 pushing the banknote stack 10 forward to push the banknote stack 10 forward and down.
