Description

Technical Field

[0001] This utility model relates to the field of vending machine technology, specifically a coin sorting and temporary storage mechanism. Background Technology

[0002] With the widespread adoption of unmanned ticketing systems, vending machines, and automatic ticketing equipment for subways and buses, the circulation scale and frequency of coin usage have increased significantly, especially in public transportation and retail supermarkets, where a large number of loose coins need to be received, counted, and circulated daily. However, there are significant technical pain points in the current coin handling process: On the one hand, existing coin handling methods mostly rely on manual sorting or large, complex equipment. Manual sorting is inefficient, time-consuming, and prone to counting errors, while large equipment is bulky, costly, and unsuitable for small terminal devices (such as small automatic ticketing machines and convenient payment terminals), failing to meet the needs of scenario-based and miniaturized use. On the other hand, the design logic of existing coin modules is mostly "receive and deposit into the coin box," lacking an intermediate temporary storage link. This makes it impossible to realize the function of returning the original coin in scenarios such as user misplacement or transaction cancellation, especially unsuitable for industries such as buses and subways that have specific process requirements for coin receiving, making it difficult to match the flexible operational needs of actual applications. In addition, some existing coin sorting devices lack sufficient sorting accuracy, which can easily lead to problems such as coin jamming and mixed packing, further affecting the stability and reliability of coin processing and failing to meet the needs of high-frequency and high-accuracy usage scenarios. Utility Model Content

[0003] The purpose of this invention is to provide a coin sorting and temporary storage mechanism to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a coin sorting and temporary storage mechanism, including a coin sorting channel, a temporary storage frame, a temporary storage base, a temporary storage positioning mechanism, a coin sorting motor, a coin sorting transmission mechanism, a 5-cent coin channel, a 1-yuan coin channel, a coin sorting block, a first positioning sensor, a second positioning sensor, a third positioning sensor, and a positioning baffle.

[0005] The output end of the coin channel branches into a 5-cent coin channel and a 1-yuan coin channel, and the output ends of the 5-cent coin channel and the 1-yuan coin channel are both set with corresponding temporary storage frames.

[0006] The temporary storage frame is detachably installed on top of the temporary storage base, the temporary storage positioning mechanism is fixed to the inner side wall of the temporary storage frame, and the positioning baffle is set inside the temporary storage frame and linked with the temporary storage positioning mechanism.

[0007] The coin-splitting motor is connected to the coin-splitting block via a coin-splitting transmission mechanism, and the coin-splitting block is movably positioned at a branch position of the coin-splitting channel.

[0008] The first positioning sensor, the second positioning sensor, and the third positioning sensor are all electrically connected to the temporary storage positioning mechanism and are respectively arranged at different heights inside the temporary storage frame.

[0009] Preferably, the coin-splitting transmission mechanism is a gear transmission mechanism or a belt transmission mechanism, with its input end fixedly connected to the output shaft of the coin-splitting motor and its output end connected to the rotating shaft of the coin-splitting block.

[0010] Preferably, the first positioning sensor, the second positioning sensor, and the third positioning sensor are all contact sensors, with their sensing ends facing the inside of the temporary storage frame and corresponding to the movement trajectory of the positioning baffle.

[0011] Preferably, the temporary storage frame has two independent chambers, which correspond to the output ends of the 5-cent coin track and the 1-yuan coin track, respectively. Each chamber is equipped with a set of positioning baffles and at least one positioning sensor.

[0012] Preferably, the coin-splitting block has a fan-shaped structure with an arc-shaped groove on its edge that matches the shape of the coin, and the rotation angle of the coin-splitting block is within a range of - degrees, used to switch the coin's transport path from the coin-splitting channel to the 50-cent coin channel or the 1-yuan coin channel.

[0013] Preferably, the temporary storage base has a positioning protrusion on the top and a corresponding positioning groove on the bottom of the temporary storage frame. The temporary storage frame can be quickly positioned and installed with the temporary storage base through the cooperation of the positioning protrusion and the positioning groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By utilizing the diameter difference between one-yuan and five-jiao coins, combined with the structural design of the coin sorting blocks and the potential energy during the coin's fall, automatic coin sorting and distribution can be achieved. Different denominations of coins can be quickly distinguished without manual intervention, effectively solving the problems of tedious and time-consuming traditional manual sorting and greatly improving coin sorting efficiency. At the same time, the adaptive design of the coin sorting channels and coin sorting blocks avoids coin jamming and mixed loading, ensuring sorting accuracy.

[0016] 2. By using a dual independent coin compartment consisting of a temporary storage frame and a temporary storage base (each capable of storing 20 coins of the corresponding denomination), temporary coin storage is achieved. With the coordinated design of the coin dispensing motor, coin dispensing transmission mechanism, and temporary storage positioning mechanism, the rotation of the temporary storage base can switch the coin recycling (entering the circulation box) or return status, perfectly solving the technical defect of existing coin modules that cannot achieve original coin return. It is especially suitable for scenarios such as buses, subways, and automatic ticket vending machines that require flexible handling of coin circulation, improving the user experience and practicality of the equipment.

[0017] 3. The coin-splitting transmission mechanism, composed of gears, achieves precise transmission between the coin-splitting motor and the temporary storage base. At the same time, through the linkage of three positioning sensors arranged at specific angles and positioning baffles, the three states of the temporary storage base—balance (receiving coins), left tilt (returning coins), and right tilt (collecting coins)—can be accurately identified. This ensures that the switching of the temporary storage base's actions is accurate and avoids problems such as coin spillage and functional failure caused by positioning deviations, thereby improving the operational stability and reliability of the mechanism.

[0018] 4. The temporary storage base adopts a V-shaped structure (low in the middle and high on both sides), which can effectively prevent coins from falling off the edge due to positional deviation when falling, ensuring the safety of coins during temporary storage and circulation, reducing the risk of coin loss and jamming, and further improving the reliability of the institution.

[0019] 5. This invention adopts a modular design, and the coin dispensing mechanism and the temporary storage mechanism can be used separately (e.g., the coin dispensing mechanism can be deployed separately when only the coin dispensing function is needed, and the temporary storage mechanism can be adapted separately when only the temporary storage function is needed), adapting to the differentiated needs of different scenarios; at the same time, the overall structure is compact and can be easily integrated into various coin processing modules, applicable to various scenarios such as buses, subways, supermarkets, and convenient payment terminals, with a wide range of applications.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The following is in conjunction with the appendix Figure 1-5 This paper provides a detailed description of a specific implementation of a coin sorting and temporary storage mechanism of the present invention. This implementation aims to clearly illustrate the structural connection, assembly relationship and workflow of the mechanism, so that the technical solution is repeatable and implementable.

[0028] The coin sorting and temporary storage mechanism includes a coin sorting channel 1, a temporary storage frame 2, a temporary storage base 3, a temporary storage positioning mechanism 4, a coin sorting motor 5, a coin sorting transmission mechanism 6, a 5-cent coin sorting channel 7, a 1-yuan coin sorting channel 8, a coin sorting block 9, a first positioning sensor 10, a second positioning sensor 11, a third positioning sensor 12, and a positioning baffle 13.

[0029] The coin channel 1 is inclined (the inclination angle is 15-30° to adapt to the potential energy requirements of falling coins). Its output end is integrally formed or detachably connected through a branch structure to form a 5-cent coin channel 7 and a 1-yuan coin channel 8. The two channels are arranged in parallel and the output ends are vertically aligned with the corresponding chambers of the temporary storage frame 2. The coin block 9 is movably installed at the branch junction of the coin channel 1 via a rotating shaft. The coin block 9 adopts a fan-shaped structure design, and its edge has arc-shaped grooves adapted to the shape of the 1-yuan and 5-cent coins. The radii of the grooves are respectively matched to the diameter of the 1-yuan coin (25mm) and the 5-cent coin (20.5mm). One end of the rotating shaft of the coin block 9 extends to the outside of the coin channel 1 and is keyed to the output end of the coin transmission mechanism 6.

[0030] The coin distribution transmission mechanism 6 uses either a gear transmission mechanism (preferably two spur gears with a module of 1.5 meshing, a transmission ratio of 1:1 to ensure transmission accuracy) or a belt transmission mechanism (using a polyurethane synchronous belt and matching synchronous pulley to avoid slippage). The input end of the coin distribution transmission mechanism 6 is fixedly connected to the output shaft of the coin distribution motor 5 via a coupling. The coin distribution motor 5 is a micro stepper motor (model 57HS22, step angle 1.8°, meeting the 0-90° rotation control requirements of the coin distribution block 9). The motor mounting base is bolted to the outer wall of the coin distribution track 1.

[0031] The top of the temporary storage base 3 is integrally formed with 2-4 positioning protrusions (the cross-section is an isosceles trapezoid, and the height is 5mm). The bottom of the temporary storage frame 2 has a corresponding positioning groove. The temporary storage frame 2 achieves quick positioning and detachable installation with the temporary storage base 3 through the interference fit between the positioning protrusions and the positioning groove. The interior of the temporary storage frame 2 is divided into two independent chambers by a partition (the volume of each chamber is adapted to the size of a single coin, ensuring that each chamber can stably store 20 coins of the corresponding denomination). The two chambers correspond one-to-one with the output ends of the 5-cent coin channel 7 and the 1-yuan coin channel 8, respectively. The temporary storage positioning mechanism 4 uses a micro geared motor (model 36GP-555, reduction ratio 1:100), which is fixed to the top of the inner side wall of the temporary storage frame 2 by bolts. The positioning baffle 13 is an L-shaped metal plate, one end of which is fixedly connected to the output shaft of the temporary storage positioning mechanism 4 by a flat key, and the other end extends into the interior of the temporary storage frame 2, and can rotate synchronously with the output shaft of the temporary storage positioning mechanism 4.

[0032] The first positioning sensor 10, the second positioning sensor 11, and the third positioning sensor 12 are all contact-type stroke sensors (model LXW5-11G2, stroke 1mm, response time ≤10ms). All three are electrically connected to the temporary storage positioning mechanism 4 via wires (connected to the signal input terminal of the motor controller). The three sensors are positioned at different heights inside the temporary storage frame 2, with their sensing ends facing the interior of the chamber and tangent to the rotation trajectory of the positioning baffle 13. The first positioning sensor 10 is located in the upper-middle part of the left side wall of the chamber (corresponding to the left-tilting coin-returning position of the temporary storage base 3), the second positioning sensor 11 is located in the upper-middle part of the right side wall of the chamber (corresponding to the right-tilting coin-returning position of the temporary storage base 3), and the third positioning sensor 12 is located in the middle of the bottom wall of the chamber (corresponding to the horizontal coin-receiving position of the temporary storage base 3). Each independent chamber of the temporary storage frame 2 is equipped with a set of positioning baffles 13 and at least one positioning sensor (in this embodiment, for structural simplification, the two chambers share a single set of three-position sensors, which are synchronously triggered by the baffles).

[0033] Workflow Description:

[0034] The working process of this coin sorting and temporary storage facility is divided into three stages: coin sorting, temporary storage, and status switching (recycling / returning), as detailed below:

[0035] Initial state: The temporary storage positioning mechanism 4 drives the positioning baffle 13 to rotate to the sensing end of the third positioning sensor 12, triggering the sensor signal. The temporary storage base 3 remains horizontal. The two independent chambers of the temporary storage frame 2 are facing the output ends of the five-cent coin channel 7 and the one-yuan coin channel 8, and are in the coin-receiving state. The coin sorting block 9 is in the initial position (the arc-shaped groove faces the central axis of the coin sorting channel 1), ready for coin sorting.

[0036] Coin sorting stage: The coins inserted by the user roll down the inclined coin channel 1, using the potential energy generated during the fall to drive themselves to the coin block 9; the coin motor 5 starts after receiving the control signal, and drives the coin block 9 to rotate around the axis through the coin transmission mechanism 6 (the rotation angle is adjusted according to the coin detection signal, ranging from 0-90°): When the coin is a one-yuan coin (25mm in diameter), the coin block 9 rotates to the position that is connected to the one-yuan coin channel 8. The one-yuan coin cannot pass through the gap between the coin block 9 and the channel wall and slides into the one-yuan coin channel 8 along the arc groove; when the coin is a five-jiao coin (20.5mm in diameter), the coin block 9 rotates to the position that is connected to the five-jiao coin channel 7. The five-jiao coin passes through the gap between the coin block 9 and the channel wall and enters the five-jiao coin channel 7, realizing the accurate sorting of coins of different denominations.

[0037] Coin storage stage: After sorting, one-yuan coins and five-jiao coins fall into the two independent chambers of the temporary storage frame 2 through the output end of the corresponding coin channel; the temporary storage base 3 adopts a V-shaped structure design (low in the middle, high on both sides, and with a 5mm high anti-drop edge), which can effectively prevent coins from falling from the edge of the chamber due to position deviation when falling, and ensure that the coins are stably stored in the chamber until the preset storage quantity (20 coins in this embodiment) is reached or the status switching signal is received.

[0038] State transition phase:

[0039] When coins need to be recycled, the control unit sends a recycling signal to the temporary storage mechanism 4. The temporary storage mechanism 4 drives the positioning baffle 13 to rotate counterclockwise. When the baffle contacts and triggers the second positioning sensor 11, the sensor sends a stop signal, the temporary storage mechanism 4 stops, and the temporary storage base 3 tilts to the right (tilting angle 15-20°). The coins in the temporary storage frame 2 slide out along the tilted bottom surface and enter the coin circulation box, completing the recycling action.

[0040] When a coin refund is needed (e.g., due to user error or transaction cancellation), the control unit sends a refund signal to the temporary storage mechanism 4. The temporary storage mechanism 4 drives the positioning baffle 13 to rotate clockwise. When the baffle contacts and triggers the first positioning sensor 10, the sensor sends a stop signal, the temporary storage mechanism 4 stops, and the temporary storage base 3 tilts to the left (tilting angle 15-20°). The coins in the temporary storage frame 2 slide out along the tilted bottom surface and are returned to the user through the refund channel, completing the coin refund action.

[0041] After the action is completed, the temporary positioning mechanism 4 reverses the rotation of the positioning baffle 13 until the third positioning sensor 12 is triggered, and the mechanism returns to the initial coin receiving state, waiting for the next working cycle.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
