For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0040] A method for unrolling and rolling a coin roll includes: making a cut at the sealing part of the bottom of one end of the coin roll, then cutting the packaging along this cut towards the other end, and opening the cut packaging to separate the coins from the packaging.

[0041] Figures 1 to 7 The coin roll unrolling and rolling device shown can implement the above coin roll unrolling and rolling method. The coin roll unrolling and rolling device includes a positioning table 1, a cutting mechanism, and a separating mechanism. The positioning table 1 is used for placing the coin roll to be unrolled.

[0042] The cutting mechanism includes a cutter 2 and a slitter 3. The slitter 3 is located downstream of the cutter 2. The cutter 2 is used for making a cut at the sealing part of the bottom of one end of the coin roll, and the slitter 3 is used for cutting the packaging along the cut at one end of the coin roll packaging. Moreover, the cutter 2 can move in a direction perpendicular to the movement of the coin roll; the separating mechanism is used for opening the packaging cut by the slitter 3 to separate the coins from the packaging, and the separating mechanism is located downstream of the slitter 3. First, the harder sealing part is cut by the cutter 2 to form a cut, and then the slitter 3 cuts the packaging during the movement of the coin roll along the cut, so that the packaging of the coin roll can be cut quickly. After cutting, the packaging and the coins are separated by the separating mechanism, which can efficiently unroll the roll. The whole working process takes a short time, and even for a large-capacity coin roll, it can be completed in a short time.

[0043] To facilitate the smooth movement of the cutter 2, the cutting mechanism further includes a driving component for driving the cutter 2 to move. The cutter 2 can move in a direction perpendicular to the movement of the coin roll. If the coin roll moves horizontally, the cutter 2 moves in the vertical direction.

[0044] The driving component includes a driving motor, a transmission gear 13, a gear plate 14, and a connecting rod 15. The transmission gear 13 is in transmission connection with the driving motor. The gear plate 14 is rotatably arranged. One end of the gear plate 14 has a gear surface meshing with the transmission gear 13. One end of the connecting rod 15 is rotatably connected to the other end of the gear plate 14, and the other end of the connecting rod 15 is connected to the cutter 2. The driving motor drives the transmission gear 13 to rotate, which drives the gear plate 14 to rotate. The rotation of the gear plate 14 drives the cutter 2 to move. The rotation point of the gear plate 14 is located between the two ends of the gear plate 14. The connecting rod 15 and the transmission gear 13 are located on both sides of the rotation point of the gear plate 14. When one end of the gear plate 14 moves upward, the other end of the gear plate 14 moves downward. The end of the gear plate 14 with the gear surface is fan-shaped. The forward and reverse rotation of the driving motor is converted by the gear plate 14 and the connecting rod 15, converting the circular arc movement of the driving motor into the up and down linear movement of the cutter 2. When the cutter 2 moves downward, the edge of the (sealing part) of the coin roll can be cut open.

[0045] The cutting knife 2 has a cutting knife surface which can be parallel to the moving direction of the coin roll. The sealed end of the coin roll has a certain length. During cutting, the height of the cutting knife 2 is higher than that of the sealed end of the coin roll, and the cutting knife surface faces the sealed end of the coin roll. Then, when the cutting knife 2 moves downward, the cutting knife surface abuts against the sealed end of the coin roll to cut open the sealed end of the coin roll to form a cut. Or the cutting knife surface of the cutting knife 2 is perpendicular to the moving direction of the coin roll, and the sealed end of the coin roll can be cut open to form a cut when the cutting knife 2 moves downward.

[0046] The cutting knife 3 is connected with an elastic member 12. The elastic member 12 gives the cutting knife 3 an elastic force to tightly press against the packaging of the coin roll and can be automatically positioned, which can ensure that the cutting knife 3 is in close contact with the lower abdomen of the packaging of the coin roll to be disassembled and has a certain pressure. The cutting knife 3 is fixedly arranged. During the movement of the coin roll towards the cutting knife 3, the cutting knife 3 can elastically press against the packaging of the coin roll and cut open the packaging of the coin roll relatively quickly.

[0047] To facilitate the movement of the coin roll, the device further includes a pushing member 4. The pushing member 4 is used to push the coin roll on the positioning table 1 towards the cutting mechanism and the separating mechanism. The pushing member 4 can adopt a cylinder or a motor. The piston rod of the cylinder is used to push the coin roll to move, or the piston rod of the cylinder is connected with a push rod 17, and the push rod 17 pushes the coin roll to move horizontally; the output shaft of the motor is used to push the coin roll to move, or the output shaft of the motor is connected with a push rod 17, and the push rod 17 pushes the coin roll to move horizontally.

[0048] The positioning table 1 is provided with a guiding groove for guiding the movement of the coin roll. The cutting knife 2, the cutting knife 3 and the separating mechanism are located in the extending direction of the guiding groove. The guiding groove is a concave groove, and the cross section of the guiding groove can be arc-shaped, which is convenient for the circular coin roll to move linearly in the guiding groove and can also prevent the coin roll from deviating during movement.

[0049] The positioning table 1 is further provided with a baffle. The baffle is arranged on one side of the guiding groove, and the extending direction of the baffle is consistent with the extending direction of the guiding groove. The arrangement of the baffle can further prevent the coin roll from deviating from the guiding groove during movement.

[0050] The device further includes a pressing block 5. The pressing block 5 is used to limit the position of the coin roll on the positioning table 1. The pressing block 5 is arranged above the positioning table 1. When the coin roll is located between the pressing block 5 and the positioning table 1, it can better limit the deviation of the coin roll during movement. The pressing block 5 is in an inverted V shape, and the groove of the inverted V shape faces the positioning table 1.

[0051] The pressing block 5 can move up and down relative to the positioning table 1. The up and down movement of the pressing block can be driven by a power member 19. The power member adopts a cylinder or a motor. A push rod can be connected to the driving shaft of the power member. One end of the push rod is connected with the pressing block 5, and the push rod is connected with the driving shaft of the power member. The positioning table 1 is provided with a guiding hole for the up and down movement of the push rod, so that the up and down movement of the push rod is smoother, which can ensure that the pressing block 5 presses against the coin roll better.

[0052] The section of the guiding groove is not provided with a first receiving channel and a second receiving channel. The cutting knife 2 is arranged in the first receiving channel. The first channel extends along the moving direction of the cutting knife 2. When cutting is required, the cutting knife 2 moves upward and extends out of the first receiving channel to abut against the sealed roll of the coin roll. When cutting is not required, the cutting knife 2 moves downward and is received in the first receiving channel without affecting the continuous movement of the coin roll towards the cutting knife 3. The cutting knife 3 is arranged in the second receiving channel, and the cutting knife 3 can be fixedly arranged.

[0053] The separating mechanism includes a first cardboard pusher 6 and a second cardboard pusher 7. The first cardboard pusher 6 and the second cardboard pusher 7 both extend in the moving direction of the coin roll, and the distance between the first cardboard pusher 6 and the second cardboard pusher 7 gradually increases from one end to the other end, such as in a V shape. During the movement of the cut coin roll, it first passes through the end with a smaller distance between the first cardboard pusher 6 and the second cardboard pusher 7, and then moves to the end with a larger distance between the first cardboard pusher 6 and the second cardboard pusher 7, which can open the package cut by the cutting knife 3 to separate the coins from the package. The coins fall first under the action of gravity, and the package falls later under the push of the pushing member 4.

[0054] One end of the first cardboard pusher 6 and the second cardboard pusher 7 can be connected to one side of the positioning table 1, and the other ends of the first cardboard pusher 6 and the second cardboard pusher 7 extend away from each other.

[0055] The separating mechanism further includes a pressing plate 8. The pressing plate 8 is arranged above the first cardboard pusher 6 and the second cardboard pusher 7. The pressing plate 8 is used to press the package cut by the cutting knife 3 against the first cardboard pusher 6 and the second cardboard pusher 7. The pressing plate 8 is in an inverted V shape, and the pressing plate 8 is an elastic pressing plate 8 that can elastically press the package of the coin roll.

[0056] The device further includes a grid vibrating screen located below the separating mechanism and a storage box located below the grid vibrating screen. The grid vibrating screen is used to receive the separated package and coins. The grid vibrating screen is provided with openings through which only the coins can pass. The storage box is used to store the coins passing through the openings on the grid vibrating screen. The unrolled coins and the packaging paper roll reach a grid vibrating screen through free fall. The diameter of the openings is larger than the diameter of the coins. Under the action of vibration, the coins fall into the storage box, while the packaging paper roll remains on the vibrating screen mesh, which can completely separate the packaging paper roll and the coins and can store them separately.

[0057] To automatically convey the coin roll to the positioning table 1, the device further includes a feeding hopper 9 and a feeding assembly. The feeding assembly is located downstream of the feeding hopper 9, and the feeding assembly is used to feed the coin roll on the feeding hopper 9 into the positioning table 1.

[0058] The coin hopper 9 has a channel for the coin roll to slide. One end of the channel is the inlet end, and the other end is the outlet end. The feeding assembly is arranged at the outlet end of the channel. The feeding channel extends obliquely downward from one end towards the other end, facilitating the automatic conveyance of a large number of coin rolls to the feeding assembly under the action of gravity without additional power. The spacing at the outlet end is slightly larger than the diameter of the coin roll, and this spacing only allows a single coin roll to pass through in sequence.

[0059] A baffle is arranged above the outlet end of the channel. The baffle extends towards the positioning table 1. A space for only a single coin roll to pass through in sequence is formed between the baffle and the feeding assembly.

[0060] The feeding wheel 10 can rotate around its own axis. The feeding wheel 10 includes a body and a plurality of wheel blades circumferentially distributed around the body. Grooves for conveying only one coin roll are formed between adjacent two wheel blades, that is, one coin roll can be conveyed to the positioning table 1 each time, and then the coin roll is unwound, realizing sequential conveyance and cutting actions, ensuring that each coin roll can be unwound.

[0061] The device includes a base and a support member. The support member is fixed on the base, and the body is rotatably connected to the support member, that is, the feeding wheel 10 rotates relative to the support member.

[0062] Or the feeding wheel 10 is arranged on the output shaft of the driving motor. The rotation of the output shaft of the driving motor can control the rotation of the feeding wheel 10. When the driving motor works, the feeding wheel 10 rotates; when the driving motor stops working, the feeding wheel 10 stops rotating.

[0063] The device further includes a limiting assembly. The limiting assembly is used to form a limiting block in the movement direction of the feeding assembly, so that the feeding assembly only conveys one coin roll to the positioning table 1 each time, preventing multiple coin rolls from entering the positioning table 1 simultaneously, causing the cutting mechanism at the positioning table 1 to malfunction, and ensuring the orderly progress of the unwinding work.

[0064] The limiting assembly has a blocking state and a non-blocking state. When in the blocking state, the limiting assembly abuts against the feeding assembly to limit the movement of the feeding assembly. When in the non-blocking state, the feeding assembly sends the coin roll on the coin hopper 9 into the positioning table 1.

[0065] The limiting assembly includes a limiting rod 11 and an electromagnet 16 connected to the limiting rod 11. The electromagnet 16 has a suction state and a release state. When the electromagnet 16 is in the release state, the limiting rod 11 abuts against the feeding assembly; when the electromagnet 16 is in the suction state, the limiting rod 11 is separated from the feeding assembly.

[0066] When the electromagnet 16 is attracted, the limit rod 11 moves downward. The feeding wheel 10 rotates counterclockwise under the gravity of the coin roll. The coin roll rotates with the feeding wheel 10 and rolls out to the left along the vanes of the feeding wheel 10 and falls onto the positioning table 1. When the electromagnet 16 is released, the limit rod 11 moves upward to block the vanes of the feeding wheel 10, and this cycle repeats.

[0067] Specific implementation method of using the coin roll unwinding device of the present application for coin roll unwinding: Place the coin roll to be unwound on the positioning table. To achieve large - batch and high - efficiency production, the coin roll can be automatically and orderly fed into the positioning table through the feeding hopper and the feeding assembly; Cutting: First, make a cut at the sealing part of the bottom of one end of the coin roll packaging with a cutter. During this process, the coin roll is moved to the cutter, and the cutter extends to contact the sealing part of the bottom of one end of the coin roll packaging. After the cutting is completed, the cutter retracts without affecting the movement of the coin roll towards the cutting knife. When a cut is made, the cutting knife then cuts the packaging along the cut at one end of the coin roll packaging. The cutting knife is set at a fixed position in the moving direction of the coin roll. The cutting knife is connected with an elastic member, and the cutting knife elastically presses against the bottom of the packaging. During the movement of the coin roll, it can cut the packaging along this cut towards the other end, and the packaging can be completely cut open. After the cutting is completed, the coin roll moves to the separation mechanism. The separation mechanism opens the packaging cut by the cutting knife to separate the coins from the packaging. After separation, the packaging and the coins can be recycled separately, with high unwinding efficiency and high automation degree.

[0068] The above - mentioned embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly, and cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
