Description

Technical Field

[0001] The present invention relates to the technical field of currency processing equipment, and particularly relates to a coin dispensing device. Background Art

[0002] An automatic coin dispenser is a device used to provide coins, game tokens or other currencies, and is widely used in arcades, entertainment venues, etc. When a user makes a purchase, the coins are sent out through an internal coin dispensing device. Therefore, the coin dispensing efficiency and smoothness of the coin dispensing device are crucial.

[0003] The coin dispensing turntable of the coin dispensing device will adopt a flat or inclined placement method. Currently, the coin dispensing devices on the market usually set the coin outlet on the side of the device for coin dispensing, and the turntable and the flying knife disc are separately arranged. Such a coin dispensing device has a simple structure. Although the coins can be transported to the side and then ejected to avoid coin accumulation at the coin outlet, the coin dispensing efficiency is low. The separation of the turntable and the flying knife disc also means that the components are prone to shaking during high-speed rotation, and the coordinated movement of the turntable and the flying knife disc requires continuous adjustment. Therefore, the rotation speed of such devices is usually not set very high, which further limits the coin dispensing rate. When the coin dispensing demand is large, users need to wait for a long time, affecting the experience. Summary of the Invention

At least part of the first blocking member and the second blocking member protrudes from the top surface of the base. The first blocking member and the second blocking member are arranged close to the coin ejecting device and are located on the moving stroke of the coin outlet. When the turntable rotates forward, the first blocking member pushes the coin in the coin outlet towards the coin ejecting device. When the turntable rotates in reverse, the second blocking member pushes the coin in the coin outlet out of the coin outlet.

[0013] Optionally, the first blocking member and the second blocking member are rotatably arranged on the base, and two inclined surfaces facing away from each other are formed at one end of the first blocking member and the second blocking member protruding from the top surface of the base.

[0016] Optionally, on the side of the turntable facing away from the base, a conical convex point is provided between adjacent coin outlets. The conical surface of the conical convex point guides the coin outlet.

[0017] Optionally, a plurality of foreign object holes are formed on the top surface of the base. The plurality of foreign object holes are located on the center locus line of the plurality of coin outlets. The outer diameter of the foreign object holes is smaller than the outer diameter of the coin.

[0018] Optionally, the coin ejecting device includes a movable roller, a fixed roller and an elastic member. The movable roller and the fixed roller are arranged on the base at intervals. The movable roller is connected to the elastic member. The movable roller approaches or moves away from the fixed roller through the elastic member to eject the coin hitting the movable roller out of the coin outlet.

[0019] Optionally, it includes a coin hopper. The coin hopper is connected to the base. The inner cavity of the coin hopper surrounds the turntable. A slope is convexly provided in the inner cavity of the coin hopper.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0036] The main object of the present invention is to provide a coin output device 100 to solve the problem of low coin output efficiency of the coin output device in the prior art.

[0037] Refer to Figures 1 to 8, in an embodiment of the present invention, a coin dispensing device 100 includes: a base 110, a turntable 120, and a coin ejecting device 130; the top surface of the base 110 is inclined, and a coin outlet 110a is provided at the lowest point of the inclined top surface of the base 110; the turntable 120 is arranged at a gap with the top surface of the base 110 and can rotate relative to the base 110, and the turntable 120 is provided with a plurality of coin outlet holes 120a, and the plurality of coin outlet holes 120a are arranged around the center of the turntable 120; a plurality of guiding arms 121 are integrally formed on the surface of the turntable 120 facing the base 110, the plurality of guiding arms 121 are arranged at intervals around the turntable 120, the guiding arms 121 extend from the edge of the turntable 120 towards the center of the turntable 120 and are tangent to the outer diameter of the coin outlet holes 120a, and an arc-shaped channel 121a is formed between adjacent guiding arms 121; when the turntable 120 rotates, the coin enters the arc-shaped channel 121a from the coin outlet hole 120a under the centrifugal force generated by the rotation of the turntable 120; the coin ejecting device 130 is arranged on the base 110 near the coin outlet 110a, when the turntable 120 rotates, the coin in the arc-shaped channel 121a hits the coin ejecting device 130 and is ejected from the coin outlet 110a, and the number of the coin outlet holes 120a is confirmed by the following formula: Where a is the number of coin outlet holes, D is the diameter of the turntable, d is the diameter of the coin outlet hole, and the number of coin outlet holes in the formula is rounded down.

[0038] In the technical solution of the present invention, the top surface of the base 110 is inclined, and the coin outlet 110a is arranged at the lowest point of the inclined surface; the turntable 120 is arranged at a gap on the top surface of the base 110, the turntable 120 is provided with a plurality of coin outlet holes 120a and integrally formed with a plurality of guiding arms 121, the plurality of guiding arms 121 are arranged at intervals around the turntable 120, the guiding arms 121 extend from the edge of the turntable 120 towards the center of the turntable 120 and are tangent to the outer diameter of the coin outlet holes 120a, and an arc-shaped channel 121a is formed between adjacent guiding arms 121; the coin ejecting device 130 is arranged near the coin outlet 110a; when the turntable 120 rotates, the coin enters the coin outlet 110a from the surface of the turntable 120, then enters the arc-shaped channel 121a from the coin outlet 110a, and finally is ejected from the coin outlet 110a through the coin ejecting device 130. Since the turntable 120 is inclined, when dispensing coins during rotation, the coin will naturally slide to the lowest point due to its own weight, and combined with the centrifugal force generated during rotation, the coin can be ejected from the coin outlet 110a faster, and the coin dispensing process is more stable and fast; in addition, since the turntable 120 is integrally formed with the guiding arms 121, synchronous movement of the guiding arms 121 and the turntable 120 is achieved, and high-speed coin dispensing can be carried out without further coordinated debugging of the two. The guiding arms 121 can send the coins entering the coin outlet holes 120a to the coin outlet 110a faster, avoiding coin accumulation while ensuring a high coin dispensing rate.

[0039] It should be noted that the turntable 120 is inclined at a certain angle and the coin outlet 110a is arranged at the lowest point of the inclined plane. The principle is to make full use of the gravity of the coin itself when the coin is discharged, and cooperate with the potential energy of the downward movement generated by the centrifugal force during rotation, so that the coin can fall to the coin outlet 110a faster. Further, in order to prevent coin jams, a coin guiding ramp 113 is extended outward at the coin outlet 110a and is surrounded by a sheet metal part to form an outlet, so that the coin can slide out smoothly; the turntable 120 of the present application has more coin outlets 120a than the turntables 120 of the same size on the market. The coin outlets 120a are arranged at equal intervals around the center of the turntable 120, so that more coins can enter the turntable 120 in the same time to achieve the effect of discharging coins quickly. Of course, in some other embodiments, the coin outlets 120a can also be arranged in other ways, such as in a matrix, irregularly arranged around the center of the turntable 120, etc., which are not limited herein; the number of coin outlets 120a is confirmed by the following formula: where a is the number of coin outlets, D is the diameter of the turntable, d is the diameter of the coin outlet, and the number of coin outlets in the formula is rounded down; the outer shape of the coin outlet 120a is designed as a funnel shape that is wider at the top and narrower at the bottom. Such a setting can make it easier for the coin to enter the coin outlet 120a, and at the same time limit the coin after entering and guide it to the arc-shaped channel 121a, improving the stability and speed of coin discharge. A plurality of guiding arms 121 are integrally formed on the back surface of the turntable 120. From Figure 6As can be seen, a part of the arc of the guiding arm 121 is tangentially attached to the outer diameter circle of the coin outlet 120a. The guiding arm 121 replaces the flying knife disc in the prior art to ensure that the coin can be accurately pushed towards the coin ejecting device 130 and ejected from the coin outlet 110a by the coin ejecting device 130. It can be understood that since the turntable 120 is arranged on the top surface of the base 110 with a gap slightly larger than the thickness of the coin, by protruding the guiding arm 121 on the surface of the turntable 120, the coin will be limited by the arc-shaped channel 121a after falling into the inclined turntable 120 and will not fall out of the turntable 120. Only when the turntable 120 rotates to the coin outlet 110a, due to the centrifugal force and downward potential energy, the coin will be ejected from the coin outlet 110a by the coin ejecting device 130 through the arc-shaped channel 121a. Preferably, the turntable 120 is integrally formed by die-casting steel. Die-casting steel has high rigidity and strength to ensure the stability of the turntable 120 during high-speed rotation. Of course, in some other embodiments, the turntable 120 can also be made of stainless steel, plastic and other materials, which is not limited herein. Further, a high-speed motor 160 is arranged below the base 110. The rotation speed of the high-speed motor 160 is 100 revolutions per minute and it has a forward and reverse rotation function. The high-speed motor 160 is connected to a drive shaft protruding from the top surface of the base 110. The turntable 120 is inserted on the drive shaft, and the drive shaft drives the turntable 120 to rotate at a high speed, so that more coins can quickly enter the coin outlet 120a, ensuring that the coin dispensing device 100 has a high coin dispensing rate. It can be understood that the high-speed coin dispensing effect of the present application is achieved through the cooperation of the above features, and a single means cannot achieve the same effect. For example, if the number of coin outlets 120a on the turntable 120 is simply increased while the coins cannot quickly enter the coin outlets 120a, it will only cause waste of the coin outlets 120a and cannot achieve high-speed coin dispensing. The coin dispensing efficiency of the coin dispensing device 100 of the present application can reach 1300 coins per minute.

[0040] When the coin dispensing device 100 of the present application is applied to a coin dispenser, a coin dispensing device 100 is arranged in the cabinet of the coin dispenser. After enough coins are pre-deposited manually, the coins are sent to the turntable through the conveying mechanism in the cabinet, and the turntable starts to rotate forward to dispense coins. Further, the turntable 120 has a reverse rotation error correction function. When the coin dispensing during forward rotation is not counted, the turntable 120 starts to rotate in reverse to restore the coin dispensing device 100 to the original normal state, avoiding more failures caused by the coin dispenser being in the wrong coin dispensing process all the time. When only one coin dispensing device 100 of the present application is arranged in the coin dispenser, the coin dispensing efficiency can reach 1300 coins per minute, while the coin dispensing efficiency of a coin dispenser using a single device in the prior art is only 600 coins per minute. If you want to improve the coin dispensing efficiency, two devices need to be arranged to dispense coins at the same time. The coin dispensing speed of the present application is more than twice that of the coin dispensing device 100 on the market.

[0041] See Figures 1 to 8, Further, in an embodiment of the present invention, a first blocking member 111 and a second blocking member 112 are spaced apart on the base 110. At least a part of the first blocking member 111 and the second blocking member 112 protrudes from the top surface of the base 110. The first blocking member 111 and the second blocking member 112 are arranged close to the coin ejecting device 130 and are located on the moving stroke of the coin outlet 120a. When the turntable 120 rotates forward, the first blocking member 111 pushes the coin in the coin outlet 120a towards the coin ejecting device 130. When the turntable 120 rotates reversely, the second blocking member 112 pushes the coin in the coin outlet 120a out of the coin outlet 120a.

[0042] Specifically, both the first blocking member 111 and the second blocking member 112 are preferably in the form of pins. The first blocking member 111 and the second blocking member 112 are arranged close to the coin outlet 110a. The first blocking member 111 and the second blocking member 112 are spaced apart and are both located on the moving stroke of the coin outlet 120a. One end of each of the two blocking members protrudes from the top surface of the base 110, and the height of the protruding part is less than the clearance distance between the turntable 120 and the base 110. Refer to Figure 6 , It can be understood that in order to prevent the guiding arm 121 from hitting the blocking member during the rotation of the turntable 120, the middle part of the guiding arm 121 is partitioned to form two notches to clear the first blocking member 111 and the second blocking member 112 respectively, so as to avoid interference between the guiding arm 121 and the two blocking members. Taking the clockwise rotation of the turntable 120 as forward rotation and the counterclockwise rotation as reverse rotation, from Figures 1 to 4It can be seen that according to the movement trajectory of the turntable 120, the first blocking member 111 and the second blocking member 112 have a sequential position. In this embodiment, when the turntable 120 rotates forward, the coin will only contact the first blocking member 111, and when it rotates backward, the coin will only contact the second blocking member 112. Therefore, when the turntable 120 rotates forward to discharge coins, when the coin enters the coin outlet hole 120a and is brought to the vicinity of the coin outlet 110a by the arc-shaped channel 121a, the continuous rotation of the turntable 120 will drive the coin to hit the first blocking member 111. Due to the interaction of forces and the centrifugal force generated during rotation, the coin will be hit by the first blocking member 111 towards the coin ejecting device 130, thereby guiding the coin to the coin outlet 110a more precisely and quickly and improving the coin discharging efficiency. When the turntable 120 rotates backward, the coin in the coin outlet hole 120a hits the second blocking member 112 and is then ejected from the coin outlet hole 120a, and the stuck coin is returned in the form of coin jumping, preventing the coin from jamming the coin discharging device 100 and avoiding more failures caused by the coin discharging machine being in an incorrect coin discharging process all the time. It should be noted that the blocking member can also adopt other forms, such as setting bumps, wavy bumps, headless screws, etc. The number and position of the blocking members can also be adjusted according to factors such as the size of the turntable 120, the rotation rule of the turntable 120, and the size of the coin, as long as it can guide the coin to the coin outlet 110a and / or eject the coin from the coin outlet hole 120a during rotation. The embodiments of the present invention are not limited thereto, and all of the above are within the protection scope of the present invention.

[0043] See Figures 1 to 8 , Further, in an embodiment of the present invention, the first blocking member 111 and the second blocking member 112 are rotatably disposed on the base 110, and one end of the first blocking member 111 and the second blocking member 112 protruding from the top surface of the base 110 is formed with two bevel surfaces arranged back to back. Specifically, the first blocking member 111 and the second blocking member 112 are rotatably disposed on the base 110 in the form of pins, and two bevel surfaces are provided at one end of the two blocking members protruding from the base 110. The bevel surfaces extend from the middle of the top end of the pin to both sides. During use, the direction of the bevel surface is adjusted by rotating the pin so that the bevel surfaces respectively face the movement trajectory line of the coin outlet hole 120a. With such a setting, when the coin hits the first blocking member 111 and / or the second blocking member 112, the bevel surfaces thereon can play a guiding and buffering role, avoiding scratching the coin and better guiding the coin to the coin ejecting device 130 or ejecting the coin from the coin outlet hole 120a.

[0044] See Figures 1 to 8, Further, in an embodiment of the present invention, a boss 122 is provided on the side of the turntable 120 facing away from the base 110. A plurality of coin outlets 120a are arranged around the boss 122. The side surface of the boss 122 guides the coin outlets 120a, and the inclination of the side surface of the boss 122 is 10° to 30°. By providing the boss 122, the coins staying on the turntable 120 can slide into the respective coin outlets 120a along the side surface of the boss 122, avoiding the coins staying on the surface of the turntable 120 for too long, resulting in coin accumulation and coin jamming. Preferably, the boss 122 and the turntable 120 are of an integrally formed structure, and the inclination of the side surface of the boss 122 is 10° to 30°. The integrated design can reduce the connection points between the boss 122 and the turntable 120, making the connection more smooth. At the same time, it can avoid the situation that the guiding effect becomes poor due to insufficient installation accuracy of the split structure. For the inclination angle of the boss 122, through testing, setting the angle within this range makes the guiding effect of the coins the best, and no matter from what angle the coins enter the turntable 120, they can slide out of the coin outlet 120a through the inclined surface of the boss 122. It should be noted that the inclination of the inclined surface of the boss 122 can be set to other angles according to the size of the turntable 120, the size of the boss 122, and the size of the coins, specifically determined according to the actual situation; in addition, in addition to the boss 122, a structure with a certain slope such as a hemispherical body can also be provided, as long as it can guide the coins to the coin outlet 120a. The embodiments of the present invention are not limited thereto, and the above are all within the protection scope of the present invention.

[0045] See Figures 1 to 8 , Further, in an embodiment of the present invention, a plurality of guiding grooves 122a corresponding to the coin outlets 120a are provided on the side surface of the boss 122. The guiding grooves 122a extend from the top surface of the boss 122 to the outer diameter of the coin outlet 120a. A convex rib is formed between adjacent guiding grooves 122a. The guiding grooves 122a are used to guide the coins to the coin outlets 120a. Specifically, according to the number of the coin outlets 120a, a corresponding number of guiding grooves 122a are formed on the side surface of the boss 122 by precision turning and milling. The cross-section of the guiding grooves 122a is U-shaped, so that a unique convex rib structure is formed at the connection of adjacent guiding grooves 122a. Each guiding groove 122a extends from the top surface of the boss 122 to the outer diameter of the coin outlet 120a in a diffused manner. It can be understood that its cross-sectional area gradually increases from the top surface to the bottom surface of the boss 122, making the guiding grooves 122a adapt to the size of the coins. With such a setting, on the one hand, by providing a corresponding guiding groove 122a for each coin outlet 120a, and the shape of the guiding groove 122a conforms to the shape of the coins, when the turntable 120 rotates, the coins can slide into the coin outlets 120a better; on the other hand, the setting of the convex ribs can ensure that when the turntable 120 rotates, no matter where the coins are on the surface of the turntable 120, they can be guided into the coin outlets 120a, improving the coin output efficiency.

[0046] See Figures 1 to 8 Figures 1 to 8 , further, in an embodiment of the present invention, on the side of the turntable 120 facing away from the base 110, tapered bumps 123 are provided between adjacent coin outlets 120a, and the tapered surface of the tapered bumps 123 guides the coin outlets 120a. Specifically, the tapered bumps 123 are arranged equidistantly around the center of the turntable 120 at the edge of the turntable 120 and are located at the gaps between two adjacent coin outlets 120a. It can be understood that when the turntable 120 rotates, the coins thrown to the edge of the turntable 120 due to centrifugal force will slide into any one of the coin outlets 120a on both sides of the tapered bumps 123 through the tapered surface, so as to ensure that the coins will not accumulate at the edge position during the rotation of the turntable 120, resulting in coin jamming, and at the same time, the coins can quickly enter the coin outlets 120a to ensure the coin output efficiency.

[0047] See Figures 1 to 8 Figures 1 to 8 , further, in an embodiment of the present invention, a plurality of foreign object holes 110b are opened on the top surface of the base 110, and the plurality of foreign object holes 110b are located on the center locus line of the plurality of coin outlets 120a, and the outer diameter of the foreign object holes 110b is smaller than the outer diameter of the coins. Specifically, along the center locus line of the plurality of coin outlets 120a, six circular foreign object holes 110b are opened on the top surface of the base 110, which are respectively arranged on both sides of the central axis of the turntable 120. When the turntable 120 is running, usually external fine foreign objects will enter the turntable 120. By providing the foreign object holes 110b, the foreign objects will fall into the foreign object holes 110b and be discharged when the turntable 120 rotates, preventing coin jamming, machine jamming and other phenomena caused by foreign objects. Preferably, the foreign object holes 110b are all arranged close to the coin outlet 110a, and the top surface of the base 110 is inclined at a certain angle, and the foreign objects will move towards the lower part of the inclined surface. Such a setting can make the foreign objects more easily enter the foreign object holes 110b. It should be noted that the shape of the foreign object holes 110b can be other shapes except circular holes, such as rectangular, triangular, other irregular polygons, etc., as long as it can achieve dropping foreign objects and ensure that the coins cannot pass through. The number of the foreign object holes 110b can also be determined according to the actual situation. The embodiments of the present invention are not limited thereto, and the above are all within the protection scope of the present invention.

[0048] See Figures 1 to 8, Further, in an embodiment of the present invention, the coin ejecting device 130 includes a movable roller 131, a fixed roller 132, and an elastic member. The movable roller 131 and the fixed roller 132 are spaced apart on the base 110. The movable roller 131 is connected to the elastic member, and the movable roller 131 approaches or moves away from the fixed roller 132 through the elastic member to eject the coin hitting the movable roller 131 out of the coin outlet 110a. Specifically, an arc-shaped groove is formed at a position on the top surface of the base 110 close to the coin outlet 110a. The movable roller 131 is movably arranged in the arc-shaped groove. The fixed roller 132 is spaced from the movable roller 131, and a narrow pass for the coin to pass through is formed therebetween. It can be understood that the width of the narrow pass can be adjusted by adjusting the position of the movable roller 131 in the arc-shaped groove to adapt to coins of different sizes. The bottom end of the movable roller 131 is connected to an elastic member. In this embodiment, the elastic member is preferably a torsion spring structure (not shown in the figure). During use, when the coin rotates with the turntable 120 and hits the movable roller 131, due to the action of force, the movable roller 131 will move away from the fixed roller 132 and compress the torsion spring. Then, the force generated by the reset of the torsion spring will push the movable roller 131 back to its original position, and the coin passes through the narrow pass and is ejected out of the coin outlet 110a. It should be noted that the elastic member can also adopt other forms, such as a spring piece, an elastic pin, an elastic ring, a spring, etc. The embodiments of the present invention are not limited thereto, and all of the above are within the protection scope of the present invention.

[0049] See Figures 1 to 8 , Further, in an embodiment of the present invention, a coin hopper 140 is included. The coin hopper 140 is connected to the base 110. The inner cavity of the coin hopper 140 surrounds the turntable 120. A slope is convexly provided in the inner cavity of the coin hopper 140. The slope guides the turntable 120, and a plurality of convex strips 141 are provided at intervals along the transverse direction of the slope. By providing a slope in the inner cavity of the coin hopper 140 to buffer the coins falling into the coin hopper 140, the coin hopper 140 has a certain compressive capacity, avoiding the situation that when a large number of coins enter the coin hopper 140, the weight is simultaneously applied to the turntable 120, resulting in excessive pressure on the turntable 120 and affecting the stability of the device operation. After testing, the coin hopper 140 of the present application can bear a weight of 160 kg, which is approximately equal to 20,000 coins. It can be understood that the coin hopper 140 can bear a sufficient number of coins to meet the high-speed coin ejection efficiency, and at the same time, the number of times of manual coin addition can be reduced; preferably, a plurality of convex strips 141 are provided at intervals on the surface of the slope, which can increase the friction between the coin and the slope surface, avoid a large number of coins pouring in in a short time, further improve the compressive capacity of the coin hopper 140, and at the same time, the convex strips 141 can also be used as a guide for the coin to slide. It should be noted that even if a plurality of convex strips 141 are not provided on the slope, the coin hopper 140 still has a certain compressive capacity

[0050] See Figures 1 to 8, Further, in an embodiment of the present invention, it includes a coin press 150. The coin press 150 is disposed above the coin outlet hole 120a and is used to guide the coins on the surface of the turntable 120 into the coin outlet hole 120a. Specifically, the coin press 150 is a plastic rod or a metal rod, and is arranged on the inner cavity wall of the coin hopper 140 through a connecting member. Preferably, it is arranged above the coin outlet hole 120a closest to the coin outlet 110a. The position of the coin press 150 can be adjusted by adjusting the connecting member so that the coin press 150 is directly opposite and as close as possible to the coin outlet hole 120a. When there are fewer coins in the turntable 120, the coins will stand up due to centrifugal force and it is difficult to enter the coin outlet hole 120a. By setting the coin press 150 to apply a force to the coins in this state, the coins can fall down and smoothly enter the coin outlet hole 120a. In this way, even if there is only one coin left in the turntable 120, it can be sent out; in addition, when there are more coins, the coin press 150 can also apply an appropriate pressure to the rotating coins to make the coins quickly enter the coin outlet hole 120a, shortening the stagnation time of the coins on the turntable 120 and achieving the effect of quickly discharging coins. It should be noted that the coin press 150 can also adopt other forms, and its installation position can also be reasonably set at other positions of the coin hopper 140 according to needs or directly connected to the base 110 through a connecting member, as long as it can achieve guiding the coins into the coin outlet hole 120a. The embodiments of the present invention are not limited thereto, and all of the above are within the protection scope of the embodiments of the present invention.

[0051] The above are only the optional embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
