Description

Technical Field

[0001] This application relates to the technical field of gaming machines, and particularly to a coin stacking device. Background Art

[0002] As a sport for us to relieve fatigue, gaming machines have become one of the important leisure ways for people. As a mainstream gaming machine, the play method of the coin pusher is that after the player inserts game coins, the game coins accumulate on the pusher plate. As the accumulated quantity increases, the game coins on the pusher plate fall into the coin outlet hopper, and the player obtains corresponding rewards. In this type of coin stacking gaming machine, the game coins are placed into a coin tower in the coin pushing area, and the user pushes or topples the coin tower forward as a reward mechanism for the player. However, the coin stacking efficiency in traditional coin stacking gaming machines is relatively low, resulting in a long waiting time for users and a poor experience. Summary of the Utility Model

[0003] The purpose of this application aims to solve at least one of the above technical defects, especially the problem of low coin stacking efficiency in the prior art.

Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0028] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0029] In the description of the embodiments of the present utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are used to indicate the orientation or positional relationship, it is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the utility model product is usually placed during use.

For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined. In the description of the embodiments of the present utility model, "a plurality of" means at least two.

[0030] Finally, it should also be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the element.

[0031] This application provides a coin stacking device, which includes a coin inlet plate 10, a coin gathering mechanism 20, a coin top column 30, a lifting and swinging mechanism 40, a first driving module 50, a second driving module 60 and a third driving module 70.

[0032] The coin inlet board 10 is connected to the coin outlet device 80 and is provided with a preset number of first coin dropping holes 110 for dropping the game coins output by the coin outlet device 80 from each of the first coin dropping holes 110 into the coin collecting mechanism 20. The coin inlet board 10 is a key component in the game coin processing system and serves as a bridge connecting the coin outlet device 80 and the coin collecting mechanism 20. The main function of the coin inlet board 10 is to receive the game coins output from the coin outlet device 80 and guide them to the coin collecting mechanism 20 below. The structural feature of the coin inlet board 10 is that it is provided with a preset number of first coin dropping holes 110. The arrangement of these first coin dropping holes 110 is carefully designed to ensure that the game coins can be evenly distributed into the coin collecting mechanism 20 below. Each first coin dropping hole 110 corresponds to a specific position in the coin collecting mechanism 20, and this one-to-one correspondence ensures the orderly distribution of the game coins. The stackable coin tower in this application is a Figure 2 rotary layered coin tower as shown, and the preset number is the number of game coins included in each layer. The aperture of the first coin dropping hole 110 must be slightly larger than the diameter of the game coin to ensure that the game coin can pass through smoothly, but not too large to avoid multiple game coins falling at the same time. The surface treatment of the coin inlet board 10 can be anti-static treatment to reduce static electricity accumulation (which may cause the game coins to adhere). In some specific embodiments, the coin inlet board 10 is provided with a coin inlet channel 120. The entrance of the coin inlet channel 120 is connected to the coin outlet device 80. The width of the coin inlet channel 120 matches the diameter of the game coin. The coin inlet channel 120 is located above each first coin dropping hole 110 so that the game coins entering the coin inlet channel 120 fall into the first coin dropping hole 110 when passing through the empty first coin dropping hole 110. A coin inlet light eye can be provided at the entrance of the coin inlet channel 120 to determine the number of game coins entering the coin inlet channel 120.

[0033] The coin accumulating mechanism 20 includes a coin accumulating plate 210, a coin stacking plate 220, a positioning core 230, and a preset number of sliders 240. The coin accumulating mechanism 20 is a core component in the game coin processing system, and its main function is to receive the game coins falling from the coin feeding plate 10 and arrange them orderly into a coin layer. Among them, the coin stacking plate 220 and the positioning core 230 are located at the center of the coin accumulating plate 210. A preset number of second coin dropping holes 221 are formed in the coin stacking plate 220, and the second coin dropping holes 221 are arranged in an array around the positioning core 230 to form a coin layer when there are game coins in each of the second coin dropping holes 221. A preset number of sliding grooves 211 are formed in the coin accumulating plate 210, and the ends of the sliding grooves 211 are the corresponding second coin dropping holes 221. The sliding grooves 211 are used to receive the game coins falling from the corresponding first coin dropping holes 110. The positioning core 230 is provided with positioning grooves corresponding to the sliding grooves 211 one by one, and the positioning grooves are used to make the game coins output from the ends of the corresponding sliding grooves 211 fall into the corresponding second coin dropping holes 221. The sliders 240 correspond to the sliding grooves 211 one by one and are connected to the first driving module 50, and are used to push the game coins received by the corresponding sliding grooves 211 to the corresponding positioning grooves under the drive of the first driving module 50.

[0034] It can be understood that in the coin accumulating mechanism 20, the sliding grooves 211 are all opened towards the center of the coin accumulating plate 210. The sliding grooves 211 are evenly and symmetrically distributed on the coin accumulating plate 210, and each sliding groove 211 corresponds to a first coin dropping hole 110. When the slider 240 is located at the end of the sliding groove 211, it will block the corresponding first coin dropping hole 110. When the slider 240 moves to the head end of the sliding groove 211, the game coins fall from the first coin dropping hole 110 of the coin feeding plate 10 into the corresponding sliding groove 211. The slider 240, under the drive of the first driving module 50, pushes the game coins on the sliding groove 211 to the end of the sliding groove 211. Under the limiting action of the positioning groove corresponding to the positioning core 230, the game coins fall into the corresponding second coin dropping hole 221 on the coin stacking plate 220. When each second coin dropping hole 221 is filled, Figure 2 a coin layer in the coin tower as shown is formed. In some embodiments, a tower protection inner ring 250 is further provided above the positioning core 230 to prevent the coin tower from falling inward.

[0035] There are a preset number of coin - lifting columns 30. One end of each coin - lifting column is fixed on the lifting and swinging mechanism 40, and the other end extends into the corresponding second coin - dropping hole 221. The coin - lifting columns 30 play an important role in the formation and movement of the coin layer. Under the control of the lifting and swinging mechanism 40, they can precisely manipulate the game coins in the second coin - dropping holes 221. The diameter of the coin - lifting column 30 is slightly smaller than the diameter of the second coin - dropping hole 221. This design ensures that the coin - lifting column 30 can freely move up and down in the second coin - dropping hole 221 while effectively supporting and moving the game coins. The lifting and swinging mechanism 40 can be lifted and can also rotate. Therefore, the lifting and swinging mechanism 40 includes a lifting platform 410 and a swinging platform 420. The coin - lifting columns 30 are arranged on the swinging platform 420. The swinging platform 420 is slidably connected to the lifting platform 410. The lifting platform 410 drives each coin - lifting column 30 to move up and down under the drive of the second drive module 60, and the swinging platform 420 drives each coin - lifting column 30 to reciprocally rotate around the center by a certain angle under the drive of the third drive module 70.

[0036] During the actual coin - stacking process, the number of game coins that can be accommodated in the coin - feeding channel 120 is more than the number of the first coin - dropping holes 110. Suppose there are 8 first coin - dropping holes 110 in total, and the coin - feeding channel 120 can accommodate 24 game coins. The slider can block the corresponding first coin - dropping hole 110 at the initial position so that the coins cannot fall. When the slider 240 slides outwards, 8 out of the 24 coins respectively fall into the corresponding sliding grooves 211. The slider 240 slides towards the center, pushing the coins in the sliding grooves 211 into the second coin - dropping holes 221. At the same time, the coin - discharging device 80 starts to discharge coins to make up 24 coins, thus saving the coin - feeding time. After that, the slider 240 returns to its original position, and then 8 more coins fall and stop. Whenever a coin layer is formed on the coin - stacking plate 220, first, the second drive module 60 drives the lifting platform 410 to rise. The new coin layer is lifted by the coin - lifting columns 30. At this time, the stacked coin tower is located above the upper cover plate 90 at the topmost layer of the entire coin - stacking device. The coin layer lifted by the coin - lifting columns 30 gradually rises, successively passing through the coin - gathering mechanism 20 and the hole opened in the center of the coin - feeding plate 10 for the coin layer, and contacting the stacked coin tower, becoming the bottom - most coin layer of the stacked coin tower. The coin - lifting columns 30 continue to lift the new coin tower until it moves to the upper limit position. Then, the third drive module 70 drives the swinging platform 420 to rotate to the offset position to drive the coin - lifting columns 30 and the coin tower lifted by the coin - lifting columns 30 to rotate together. At this time, the second drive module 60 drives the lifting platform 410 to move to the lower limit position and places the coin tower on the upper cover plate 90. Since the coin tower has rotated, the coin layer replenished next time will have an angular offset from the previous coin layer, and thus a rotating - type layered coin tower can be gradually accumulated. Finally, the third drive module 70 drives the swinging platform 420 to move to the restored position, waiting to start the next round of coin - layer stacking. In addition, at the center position of the upper cover plate 90, a tower - protecting outer ring 91 can be set. The inner diameter of the tower - protecting outer ring 91 is larger than the diameter of the coin tower, which is used to prevent the coin tower from falling outward.

[0037] In the coin stacking device of this embodiment, the design of the coin feeding plate 10 ensures that game coins can be evenly distributed into the coin gathering mechanism 20, reducing the possibility of jamming and coin sticking. The coin gathering mechanism 20 includes a coin gathering plate 210, a coin stacking plate 220, a positioning core 230, and a slider 240, which jointly act to form an orderly coin layer, improving the processing efficiency of game coins. The design of the coin pushing column 30 allows for precise control and movement of the coin layer, enhancing the flexibility of the system. The lifting and swinging mechanism 40 realizes multi-dimensional control of the coin pushing column 30 through the coordinated operation of the lifting platform 410 and the swinging platform 420, making it possible to form a rotating layered coin tower efficiently and cyclically. For the entire device, the mutual cooperation of each component can quickly form a coin layer and cyclically and efficiently accumulate it into a coin tower, improving the coin stacking efficiency. It can also be applied to stack coin towers of various scales and sizes, enhancing the flexibility of coin stacking.

[0038] In one of the embodiments, the first driving module 50 includes a coin gathering motor 510 and a first transmission unit. Each slider 240 is connected to the coin gathering motor 510 through the first transmission unit. It can be understood that the coin gathering motor 510 is the power source for the coin gathering function, and the power provided by the coin gathering motor 510 is transmitted to each slider 240 through the first transmission unit, so that the slider 240 can reciprocate on the corresponding chute 211.

[0039] In one embodiment, the first transmission unit includes a meshing gear 520, a power gear 530 and a first transmission member. The meshing gear 520 is connected to the coin gathering motor 510. The power gear 530 is concentric with the coin gathering plate 210 and meshes with the meshing gear 520. The coin gathering motor 510 can drive the meshing gear 520 to rotate, and the meshing gear 520 in turn drives the power gear 530 to rotate around the center of the coin gathering plate 210. Guide grooves 540 corresponding to the respective sliders 240 are formed in the power gear 530. The shape, size and position of the guide grooves 540 directly determine the movement trajectory of the sliders 240. Generally, the guide grooves 540 are designed to be a certain curved shape to achieve the reciprocating movement of the sliders 240. The first transmission members correspond to the sliders 240 one by one. One end of the first transmission member is connected to the slider 240, and the other end extends into the guide groove 540. When the power gear 530 rotates, the guide grooves 540 will rotate together, and the first transmission member will move under the action of the guide grooves 540 to drive the connected slider 240 to move on the corresponding sliding groove 211. By controlling the rotation direction and the rotation angle each time of the coin gathering motor 510, the slider 240 can move from the head end to the tail end, pushing the game coins to the second coin dropping hole 221 to form a new coin layer. Then it moves from the tail end to the head end to complete the reset, waiting for the game coins to drop from the first coin dropping hole 110. The stacking of the coin tower is completed in a cycle. In order to control the rotation direction and the rotation angle each time of the coin gathering motor 510, two microswitches 550 can be set to control the forward rotation and the reverse rotation of the coin gathering motor 510 respectively. That is, after the coin gathering motor 510 drives the slider 240 to move from the head end to the tail end, the micro-motion trigger member provided on the power gear 530 will contact one of the microswitches 550, stopping the coin gathering motor 510 from continuing to work and changing the rotation direction of the coin gathering motor 510. After driving the slider 240 to move from the tail end to the head end, the trigger member provided on the power gear 530 will contact another micro-motor, stopping the coin gathering motor 510 from continuing to work and changing the rotation direction of the coin gathering motor 510.

[0040] In one embodiment, the second driving module 60 includes a lifting motor 610 and a second transmission unit 620. The lifting platform 410 is connected to the lifting motor 610 through the second transmission unit 620. It can be understood that the lifting motor 610 is the power source for the up and down movement of the lifting and swinging mechanism 40. The power provided by the lifting motor 610 is transmitted to the lifting platform 410 through the second transmission unit 620, so that the lifting platform 410 can drive the entire lifting and swinging mechanism 40 to move up and down. In addition, in order to ensure that the lifting platform 410 can move up and down better, lifting guide columns 430 connected between the mounting base 92 and the coin gathering plate 210 are respectively provided at the four corner points of the lifting platform 410. The mounting base can serve as the base of the entire coin stacking device, providing support for the entire coin stacking device, and can also serve as the installation foundation for some components.

[0041] In one embodiment, the second transmission unit 620 includes a ball joint. The design of the ball joint endows it with self-aligning ability, which can compensate for installation errors in the system or deformations during operation to a certain extent. Compared with rigid connections, the ball joint can reduce stress concentration during movement and extend the service life of the system. Therefore, the use of the ball joint enables the movement of the lifting motor 610 to be transmitted to the lifting platform 410 more smoothly, while also increasing the fault tolerance and reliability of the system.

[0042] In one embodiment, in order to achieve precise control of the lifting platform 410, the coin stacking device is also provided with a corresponding position detection mechanism, including a first baffle 411, a second baffle 412, a first light sensor 413 and a second light sensor 414. The first light sensor 413 and the second light sensor 414 are fixed to the lifting platform 410. The first light sensor 413 is used to output a first in-place signal when the first baffle 411 is in its detection area, and the second light sensor 414 is used to output a second in-place signal when the second baffle 412 is in its detection area. The first baffle 411 is fixed at a first set position of the coin stacking device, so that when the lifting platform 410 moves to the upper limit position, the first baffle 411 is in the detection area of the first light sensor 413. The second baffle 412 is fixed at a second set position of the coin stacking device, so that when the lifting platform 410 moves to the lower limit position, the second baffle 412 leaves the detection area of the second light sensor 414. The first light sensor 413 and the second light sensor 414 are photoelectric sensors fixed on the lifting platform 410. They will move along with the movement of the lifting platform 410. When the lifting platform 410 moves to the upper limit position, the first baffle 411 will be in the detection area of the first light sensor 413, causing the first light sensor 413 to output a first in-place signal. After detecting the first in-place signal, it is necessary to control the lifting motor 610 to stop driving the lifting platform 410 from rising further. When the lifting platform 410 moves to the lower limit position, the second baffle 412 will change from being originally in the detection area of the second light sensor 414 to exiting the detection area of the second light sensor 414. That is, once the second in-place signal disappears, it can be determined that the lifting platform 410 has moved to the lower limit position, and it is necessary to control the lifting motor 610 to stop driving the lifting platform 410 from descending further. Figure 1 The first baffle 411 and the second baffle 412 in are two baffles that are parallel to each other and perpendicular to the ground, but have different lengths. Among them, the length of the second baffle 412 is greater than the length of the first baffle 411.

[0043] In one embodiment, the third driving module 70 includes a swing motor 710 and a third transmission unit. The lifting and swinging mechanism 40 is connected to the lifting motor 610 through the third transmission unit. It can be understood that the swing motor 710 is the power source for the rotational movement of the lifting and swinging mechanism 40. The power provided by the swing motor 710 is transmitted to the lifting platform 410 through the third transmission unit, so that the lifting platform 410 can drive the entire lifting and swinging mechanism 40 to move up and down.

[0044] In one embodiment, the third transmission unit includes an eccentric wheel 720 and a second transmission member 730. The eccentric wheel 720 is respectively connected to the swing motor 710 and the second transmission member 730, and the second transmission member 730 is connected to the swing platform 420. It can be understood that the eccentric wheel 720 is characterized in that the center of rotation of the wheel does not coincide with the geometric center. It can drive the second transmission member 730 to draw an arc in space. The other end of the second transmission member 730 is connected to a guide groove provided at the edge of the swing platform 420. During the process of the second transmission member 730 drawing an arc, it can drive the swing platform 420 to perform a reciprocating swing movement under the limiting action of the guide groove.

[0045] In one embodiment, in order to achieve precise control of the swing platform 420, the coin stacking device is further provided with a corresponding position detection mechanism, including a third baffle 740, a third light eye 741 and a fourth light eye 742. The third light eye 741 and the fourth light eye 742 are fixed to the lifting platform 410. The third light eye 741 is used to output a third in-place signal when the third baffle 740 is in its own detection area, and the fourth light eye 742 is used to output a fourth in-place signal when the third baffle 740 is in its own detection area. The third baffle 740 is fixed to a third set position of the swing platform 420, so that when the swing platform 420 rotates to the offset position, the third baffle 740 is in the detection area of the third light eye 741, and when the swing platform 420 moves to the restored position, the third baffle 740 is in the detection area of the fourth light eye 742. It can be understood that the third light eye 741 and the fourth light eye 742 are photoelectric sensors fixed on the lifting platform 410, which do not move with the movement of the swing platform 420, while the third baffle 740 is fixed to the swing platform 420 and will move with the movement of the swing platform 420, and can mark the position of the swing platform 420. When the swing platform 420 moves to the offset position, the third baffle 740 will be in the detection area of the third light eye 741, so that the third light eye 741 outputs a third in-place signal. When the swing platform 420 moves to the restored position, the third baffle 740 will be in the detection area of the fourth light eye 742, so that the fourth light eye 742 outputs a fourth in-place signal. According to the output of the third light eye 741 and the fourth light eye 742, it can be determined whether the swing platform 420 has moved in place, so as to control the swing motor 710.
