Description

Technical Field

[0001] The present invention relates to the technical field of coin counting, and particularly to a coin separation and counting method and device thereof. Background Art

[0002] Some departments such as banks, bus companies, and supermarkets need to efficiently process a large number of coins through coin automatic processing equipment, such as automatic devices for sorting and counting. However, the corresponding equipment is not perfect, and there have been phenomena such as a large number of coins settling and the obstruction of circulation. Therefore, it is of great significance to develop a coin separation and counting method and device thereof. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a coin separation and counting method and device thereof, which has a simple structure, low cost, and can completely separate coins of different denominations and accurately count them.

[0004] To solve the above technical problem, the present invention adopts the following technical solutions:

[0005] A coin separation and counting method uses a conveying mechanism with a magnetic attraction function to convey mixed coins to a separation track for separation, and separates the coins by using the size difference of the coins; the counting method is applicable to coins that can be magnetically attracted.

[0006] A coin separation and counting device for implementing the above coin separation and counting method includes an initial coin storage component for storing mixed coins, a conveying mechanism for transferring coins, a separation component for separating mixed coins, and a counting component for recording the number of separated coins; the separation component includes a separation track connected to the conveying mechanism, and a first separation slot and a second separation slot are sequentially arranged on the separation track. The separation component further includes a first storage basket and a second storage basket corresponding to the first separation slot and the second separation slot, and a third storage basket arranged at the end outlet of the separation track.

[0007] Further, the separation track is composed of a sliding bottom plate for coin sliding and a limiting baffle arranged on one side of the sliding bottom plate. The cross-section of the separation track is L-shaped. The sliding bottom plate forms an angle of 40-50° with the horizontal plane, and the height of one side edge of the sliding bottom plate connected to the limiting baffle is lower than the height of the other opposite side edge.

[0008] Further, the initial coin storage component includes a separation box for storing mixed coins, a coin-pushing claw for pushing coins to the conveying mechanism, and a driving mechanism for driving the coin-pushing claw to push coins.

[0009] Further, the box to be separated is cylindrical. The coin pusher claw includes a central rotating shaft rod disposed at the center point of the bottom of the box to be separated. The driving mechanism uses a driving motor to drive the central rotating shaft rod to rotate. A plurality of coin pushing claws are provided on the central rotating shaft rod. The coin pushing claws are arc-shaped, and the height of the end close to the central rotating shaft rod is higher than the height of the end close to the box wall in the cross-section perpendicular to the bottom of the box to be separated.

[0010] Further, the conveying mechanism includes a conveyor belt and a coin jamming plate disposed above the box to be separated. An absorbing coin roller is provided inside the front end of the conveyor belt, and a driven roller is provided inside the end of the conveyor belt. A magnetic attracting block is provided inside the absorbing coin roller.

[0011] Further, the absorbing coin roller includes a rotating shaft, a rotating shaft sleeve, and a driving motor for driving the absorbing coin roller to rotate. Connecting support rods are provided between the inner wall of the rotating shaft and the rotating shaft sleeve. A plurality of card slots are evenly arranged on the inner wall of the rotating shaft sleeve, and the magnetic attracting blocks are evenly distributed on the inner walls of the card slots.

[0012] Further, the counting component uses an optical counter, and the optical counters are provided at the entrances corresponding to the first storage basket, the second storage basket, and the third storage basket.

[0013] Advantages of the present invention:

[0014] In actual use scenarios, a large number of messy coins fall into the box to be separated. The coin pusher claw rotates around the axis to push the coins under the absorbing coin roller. The absorbing coin roller adsorbs the coins onto the conveyor belt. The coin jamming plate above the conveyor belt causes the stacked coins to fall back into the box to be separated, ensuring that only one coin enters the separation track at the end of the conveyor belt each time. The coins move along the edge of the separation track under the action of gravity. Coins of different sizes fall at the corresponding card slots under the influence of their own gravity, thereby realizing the separation of coins of different sizes. The structure of this device is simple and is used for some special departments such as small banks, bus companies, and supermarkets that need to efficiently process a large number of coins through coin automatic processing equipment. It does not require high manufacturing costs and is more practical than intelligent equipment. Description of the Drawings

Detailed implementation manners

[0021] For the convenience of understanding by those skilled in the art, the present invention will be further described below in conjunction with embodiments and the accompanying drawings. The content mentioned in the implementation manners does not limit the present invention.

[0022] As Figures 1-4 shown, the present invention provides a coin separation and counting device, including an initial coin storage component 1 for storing mixed coins, a conveyor mechanism 2 for transferring coins, a separation component 3 for separating mixed coins, and a counting component 4 for recording the number of separated coins; the separation component 3 includes a separation track 31 connected to the conveyor mechanism 2, a first separation through slot 32 and a second separation through slot 33 are sequentially arranged on the separation track 31, the separation component 3 further includes a first storage basket 34 and a second storage basket 35 corresponding to the first separation through slot 32 and the second separation through slot 33, and a third storage basket 36 arranged at the end outlet of the separation track 31.

[0023] In this embodiment, in order to use a transfer mechanism with a magnetic attraction function to transfer mixed coins to a separation track for separation, and use the size difference of coins for the coin separation method, the main objects of coin sorting by this device are the fifth edition of coins that can be magnetically attracted. During operation, the mixed coins are placed on the initial coin storage component 1, and then the transfer mechanism 2 is used to transfer the mixed coins on the initial coin storage component 1 to the separation track 31. By using the driving force during the coin transfer process on the transfer mechanism 2 and the self-gravity of the coins, the coins are pushed along the separation track 31 to the first separation slot 32. The length of the first separation slot 32 is set to 20 mm, the width is 21 mm. The 10-cent coins with a smaller diameter fall through the first separation slot 32 into the first storage basket 34 and are collected. The diameters of the 50-cent coins and 1-yuan coins are greater than the length and width of the first separation slot 32, so they continue to slide forward to reach the second separation slot 33. The length of the second separation slot 33 is set to 23 mm, the width is 21 mm. The 50-cent coins with a slightly smaller diameter fall through the second separation slot 33 into the second storage basket 35 and are collected. The diameter of the 1-yuan coin is greater than the length and width of the second separation slot 33, so it continues to slide forward to the end of the separation track 31 and falls into the third storage basket 36 and is collected. During the above separation process, the counting component 4 respectively records the quantities of the three types of coins separated. The structure of this device is simple and is used for some special departments such as small banks, bus companies, and supermarkets that need to efficiently process a large number of coins through coin automatic processing equipment. It does not require high manufacturing costs and is more practical compared to intelligent equipment.

[0024] As Figure 1 , 4 shown, the separation track 31 is composed of a sliding bottom plate 311 for coin sliding and a limiting baffle 312 arranged on one side of the sliding bottom plate 311. The cross-section of the separation track 31 is L-shaped. The sliding bottom plate 311 forms an angle of 40 - 50° with the horizontal plane. The set height of one side edge of the sliding bottom plate 311 connected to the limiting baffle 312 is lower than the height of the other opposite side edge. In this embodiment, all the mixed coins move together with the conveyor belt 21 and are transferred to the sliding bottom plate 311. The sliding bottom plate 311 is provided with a transition arc corner. At the end of the conveyor belt 21, when it enters the separation track 31, it turns at the arc corner and continues to slide forward along the sliding bottom plate 311 to the corresponding separation position for separation. The overall shape of the separation track is L-shaped, and the overall inclination angle with the horizontal plane is set to 45° to facilitate the coins to slide forward under the action of their own gravity. The set height of one side edge of the sliding bottom plate 311 connected to the limiting baffle 312 is lower than the height of the other opposite side edge, so that the side of the coin contacts the limiting baffle 312 to define the sliding trajectory and facilitate separation at the end.

[0025] As Figure 1 , 3As shown in the figure, the initial coin storage component 1 includes a separation box 11 for storing mixed coins, a coin pusher claw 12 for pushing the coins to the conveying mechanism 2, and a driving mechanism 13 for driving the coin pusher claw 12 to push the coins. The separation box 11 is in the shape of a round barrel. The coin pusher claw 12 includes a central rotating shaft rod 121 disposed at the center point of the bottom of the separation box 11. The driving mechanism 13 uses a driving motor to drive the central rotating shaft rod 121 to rotate. A number of coin pusher claws 122 are provided on the central rotating shaft rod 121. The coin pusher claws 122 are arc-shaped. The height of the end of the cross-section perpendicular to the bottom of the separation box 11 close to the central rotating shaft rod 121 is higher than the height of the end close to the box wall. In this embodiment, the mixed coins to be separated are placed in the separation box 11. The driving motor drives the central rotating shaft rod 121 to rotate, thereby driving the coin pusher claws 122 to rotate at the bottom of the box, pushing the coins in the separation box 11 towards the conveying mechanism 2. The coin pusher claws 122 are arc-shaped, and the height of the end of the cross-section perpendicular to the bottom of the separation box 11 close to the central rotating shaft rod 121 is higher than the height of the end close to the box wall, so that the extra coins above the edge can fall back to the original position, and only a small amount of coins are pushed to the edge of the box wall. The arc-shaped coin pusher claws 122 can disperse the force on the pusher claws, and the resultant force on the coins points to the edge of the separation box 11. Through repeated experiments, it is found that the most suitable rotation speed of the central rotating shaft rod 121 is set at 35 r / min. The material used for the coin pusher claws 122 must have a certain elasticity to make the coin pushing process more gentle.

[0026] As Figure 1 , 2 shown in the figure, the conveying mechanism 2 includes a conveyor belt 21 and a coin blocking plate 24 disposed above the separation box 11. An absorbing roller 22 is provided inside the front end of the conveyor belt 21. A driven roller is provided inside the end of the conveyor belt 21. A magnetic attracting block 23 is provided inside the absorbing roller 22. The absorbing roller 22 includes a rotating shaft 221, a rotating shaft sleeve 222, and a driving motor for driving the absorbing roller to rotate. A connecting support rod 223 is provided between the inner walls of the rotating shaft 221 and the rotating shaft sleeve 222. A number of card slots 224 are uniformly arranged on the inner wall of the rotating shaft sleeve 222. The magnetic attracting blocks 23 are uniformly distributed on the inner walls of the card slots 224. In this embodiment, when the driving motor is started and the driving motor drives the rotating shaft 221 and the rotating shaft sleeve 222 to drive the conveyor belt 21 to rotate, the coins will be sucked up and attached to the surface of the front end of the conveyor belt 21 and then conveyed to the separation track 31 along with the conveyor belt 21. The coin blocking plate 24 is provided. The distance between the coin blocking plate 24 and the surface of the conveyor belt 21 is slightly greater than the thickness of one coin, which is used to make the extra coins stacked on the surface of the conveyor belt 21 fall back into the separation box 11 again, ensuring that only one coin is arranged on the conveyor belt 21 at a time. The magnetic attracting blocks 23 are embedded in the rotating shaft sleeve 222 by setting the card slots 224, which can make the magnetic attracting effect better and the suction more uniform.

[0027] As shown Figure 1 In the figure, the counting component 4 uses an optoelectronic counter, and the optoelectronic counter is provided at the entrances corresponding to the first storage basket 34, the second storage basket 35, and the third storage basket 36. In this embodiment, the entire optoelectronic counter system is composed of four parts: an optoelectronic sensing circuit, an operational amplifier circuit, a single-chip microcomputer system circuit, and a display counting circuit. The optoelectronic sensing circuit converts the change of the object to be counted into an electrical signal, which is counted by the display counting circuit and then displayed by a digital display tube. A coin clamping plate 24 is provided at the front end of the conveying mechanism 2. Even if 2-3 coins are stacked overlappingly after passing through the coin clamping plate, due to the inclination of the separation track 31, they can be automatically separated when just entering the sliding bottom plate 311. Therefore, coins of different denominations can be separated completely, facilitating accurate counting by the optoelectronic counter.

[0028] All technical features in this embodiment can be modified in appearance according to actual needs.

[0029] The above embodiment is a preferred implementation solution of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution of the present invention is within the protection scope of the present invention.
