Description

Technical Field

[0001] The present invention relates to the technical field of mahjong machines, in particular to an automatic mahjong machine. Background Art

[0002] Mahjong is a popular intellectual game. After a round of play, the cards need to be shuffled. This step is cumbersome and time-consuming. Therefore, a mahjong machine capable of automatic shuffling has been invented. The existing automatic mahjong machine includes a main machine, a shuffling chamber is provided in the main machine, and a shuffling plate is provided in the center of the shuffling chamber. The mahjong tiles pushed in from the card inlet on the table fall into the shuffling chamber. The rotation of the shuffling plate not only shuffles the order of the mahjong tiles, but also makes the mahjong tiles flipped to the same side facing up, so that they can be captured by the card feeding component and then sorted.

[0003] In the existing shuffling chamber, there is only one shuffling plate, and all mahjong tiles are stacked on the shuffling plate, so the shuffling efficiency is low and the noise is relatively loud. Affected by the motor power and other factors, the diameter of a single shuffling plate cannot be made too large, and the size of the shuffling chamber is determined according to the size of the shuffling plate, so the space under the entire host cannot be fully utilized, reducing the space utilization rate.

[0004] Therefore, we set up at least two shuffling trays in the shuffling bin to solve the above technical problems, but the structure of the card entrance remains basically unchanged. Originally, there was a shuffling tray located directly below the card entrance, and the mahjong tiles could be pushed in from the card entrance and fall directly onto the shuffling tray. However, now there are at least two shuffling trays in the shuffling bin. If one shuffling tray is directly below the card entrance, there will be a problem of serious uneven distribution of the number of mahjong tiles on the shuffling tray. Therefore, no shuffling tray is located directly below the card entrance, which poses the problem of how to guide the mahjong tiles onto the shuffling tray. Summary of the invention

[0005] The object of the present invention is to provide an automatic mahjong machine, which can effectively solve the problem of how to guide the mahjong tiles pushed into the tile inlet to the shuffling tray.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The automatic mahjong machine comprises a mainframe, wherein the mainframe comprises a shuffling bin and a table top located above the shuffling bin, wherein the table top is provided with a card entry for pushing mahjong tiles into the shuffling bin, wherein a card guide and at least two adjacent shuffling trays are arranged in the shuffling bin, wherein the card guide is provided with a card guide surface for guiding mahjong tiles falling from the card entry to the shuffling trays, wherein the card guide surface is located between the card entry and the shuffling trays, and wherein the horizontal height of the card guide surface close to the card entry is greater than the horizontal height of the card guide surface close to the shuffling trays.

[0008] In the above automatic mahjong machine, the card guide surface is located on the outer periphery of the shuffle plate near the card entrance, and a blocking surface is provided in the shuffle chamber corresponding to each shuffle plate, and the blocking surface is located on the outer periphery of the shuffle plate away from the card entrance. The blocking surface and the card guide surface together confine the mahjong cards on the shuffle plate. During the shuffling process, the mahjong cards will be affected by various forces such as the centrifugal force generated by the rotation of the shuffle plate and its own gravity, and this structure can prevent the mahjong cards from sliding off the shuffle plate or shifting to other areas due to the force, ensuring that the mahjong cards are always shuffled within the specified shuffle plate range, thereby improving the stability and accuracy of the shuffle.

[0009] In the above-mentioned automatic mahjong machine, the blocking surface and the card guide member are combined into a closed ring to separate the shuffling plates independently. The blocking surface and the card guide member are combined into a closed ring to separate the shuffling plates independently, so that each shuffling plate is in a relatively independent and stable spatial environment when working. During the shuffling process, the rotation of each shuffling plate and the movement of the mahjong tiles do not interfere with each other, avoiding the problems of mahjong confusion and increased collision of mahjong tiles caused by the mutual influence between adjacent shuffling plates, ensuring that each shuffling plate can efficiently shuffle the mahjong tiles in the expected manner, thereby improving the shuffling stability and reliability of the entire automatic mahjong machine. Because it is a closed ring, the mahjong tiles entering the shuffling plate will also have more opportunities to be shuffled and turned over.

[0010] In the above-mentioned automatic mahjong machine, the card guide member is provided with a connector connecting the corresponding blocking surface and the card guide surface. The card guide member is provided with a connector connecting the corresponding blocking surface and the card guide surface, so that the card guide member, the blocking surface and the card guide surface form an organic whole structure, which better separates the shuffling plate independently. During the frequent shuffling operation of the automatic mahjong machine, this connection structure can better withstand the impact, vibration of the mahjong tiles and various stresses generated by the operation of the machine, reduce the relative displacement and looseness risk between the components, thereby improving the stability and reliability of the entire structure, and ensuring the continuous effectiveness of the card guide and blocking functions during long-term use.

[0011] In the above automatic mahjong machine, the bottom edge of the card guide surface and the bottom surface of the separator are lower than the contact surface between the shuffling plate and the mahjong tiles. Under the action of gravity, the mahjong tiles can more easily slide smoothly along the card guide surface to the corresponding shuffling plate, reducing the stuck and piled-up mahjong tiles caused by the bottom surface being too high, making the guiding process of the mahjong tiles smoother, which helps to improve the shuffling efficiency of the entire automatic mahjong machine.

[0012] In the above automatic mahjong machine, the blocking surface and the card guide surface are combined to form a ring with a gap, and the gap is connected to the adjacent shuffle plates. This connection structure can make the mahjong cards appropriately adjusted and redistributed between different shuffle plates according to actual conditions. If there are too many mahjong cards in one shuffle plate, they can overflow from the gap to the adjacent shuffle plate, speeding up the shuffle speed, avoiding the situation where there are too many or too few mahjong cards on some shuffle plates, further optimizing the distribution balance of mahjong cards on multiple shuffle plates, and improving the shuffle efficiency.

[0013] In the automatic mahjong machine, a second separation edge is formed between adjacent blocking surfaces. The second separation edge is provided to prevent mahjong tiles from getting stuck between adjacent blocking surfaces. After hitting the second separation edge, the mahjong tiles cannot stay and directly slide into the shuffling tray.

[0014] In the automatic mahjong machine, the bottom end of the second dividing edge is lower than the shuffling plate, so as to avoid the mahjong tiles being stuck between the second dividing edge and the shuffling plate, and ensure that the mahjong tiles can be guided into the shuffling plate.

[0015] In the above automatic mahjong machine, the card guide also includes a first separation edge located between adjacent card guide surfaces. The first separation edge is provided to prevent mahjong tiles from being stuck between adjacent card guide surfaces. After hitting the first separation edge, the mahjong tiles cannot stay and will be guided to the nearby card guide surface and then fall into the shuffling tray.

[0016] In the automatic mahjong machine, the horizontal height of the bottom end of the first separation edge is lower than the horizontal height of the shuffling plate, so as to avoid the mahjong tiles being stuck between the first separation edge and the shuffling plate, and ensure that the mahjong tiles can be guided into the shuffling plate.

[0017] In the above automatic mahjong machine, the height of the guide surface gradually decreases and the width gradually increases from the center of the shuffle bin to the edge of the corresponding shuffle disk. The height of the guide surface gradually decreases and the width gradually increases from the center of the shuffle bin to the edge of the corresponding shuffle disk. This design conforms to the movement law of mahjong tiles under the action of gravity. The gradual decrease in height provides a natural sliding slope for mahjong tiles, so that they can move relatively smoothly from the vicinity of the card entry to the shuffle disk; the gradual increase in width provides a wider accommodating space for mahjong tiles, avoiding congestion or poor sliding of mahjong tiles due to narrow space during the guiding process. Thereby, the guiding efficiency of mahjong tiles from the card entry to the shuffle disk is effectively improved, the residence time of mahjong tiles on the guide surface is reduced, and the shuffle process is accelerated. This design enables mahjong tiles to be more evenly distributed on each shuffle disk. Due to the special shape of the guide surface, mahjong tiles can be guided to slide in an orderly manner, avoiding the concentrated accumulation or uneven distribution of mahjong tiles in a certain area, so that each shuffle disk is in a relatively balanced state when initially receiving mahjong tiles. This is conducive to each shuffling plate being able to operate mahjong tiles of roughly the same number and distribution status during the subsequent shuffling process, thereby improving the shuffling uniformity of the entire automatic mahjong machine, improving the shuffling effect and quality, and providing players with a fairer game environment.

[0018] In the above-mentioned automatic mahjong machine, the bottom edge of the card guide surface is in an arc shape and is adapted to the curvature of the outer ring of the shuffle plate, and the two are gap-matched. The arc-shaped design of the bottom edge of the card guide surface is adapted to the curvature of the outer ring of the shuffle plate and the gap is matched. In the process of guiding mahjong tiles, it is ensured that the card guide surface does not affect the normal operation of the shuffle plate, and the mahjong tiles are prevented from getting stuck in the gap between the card guide surface and the shuffle plate, ensuring that the mahjong tiles can smoothly slide from the card guide surface to the shuffle plate, maintaining the smoothness of the shuffle process, avoiding equipment failure and shuffle interruption caused by card problems, and improving the operation stability and reliability of the automatic mahjong machine.

[0019] In the above automatic mahjong machine, all shuffling plates are arranged on a circular track with the center of the shuffling bin as the center, the card guide is located in the center of the shuffling bin, and the card inlet is located directly above the card guide. This layout allows the mahjong tiles to be dispersed and guided to the surrounding shuffling plates in a relatively balanced manner after falling from the card inlet. Compared with a messy layout, this design makes full use of the space of the shuffling bin, reduces mutual interference and collision of mahjong tiles during the guiding process, improves the efficiency and uniformity of the card flow guidance, and helps to improve the overall shuffling effect.

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] The card guide surface on the card guide piece solves the current problem of how to guide the mahjong tiles pushed into the card entry to the shuffle tray. Since there is no shuffle tray directly below the card entry, the card guide surface becomes the key guide path for the mahjong tiles from the card entry to the shuffle tray. It ensures that the mahjong tiles falling from the card entry can be accurately guided to the corresponding shuffle tray, avoiding the disordered accumulation or uneven distribution of mahjong tiles in the shuffle bin, so that each shuffle tray can receive mahjong tiles in an orderly manner for shuffling operations, ensuring the smoothness and efficiency of the entire automatic mahjong machine shuffling process. In addition, the card guide surface can also prevent the mahjong tiles pushed from the card entry from falling directly into the shuffle bin between adjacent shuffle trays, ensuring that all mahjong tiles can fall on the shuffle tray and be processed by the shuffle tray. It is an important component for realizing the efficient operation of the multi-shuffle tray structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Embodiment 1:

[0039] See also Figures 1 to 5 This is the first embodiment of the automatic mahjong machine of the present invention. The automatic mahjong machine includes a main machine, which includes a shuffling chamber 100 with an opening at the top and a tabletop disposed on the top of the shuffling chamber 100 for closing the shuffling chamber 100. An entry port for pushing mahjong tiles 300 into the shuffling chamber 100 is provided in the center of the tabletop. When people are having fun, the entry port is closed by a dice plate 1000. When a game of mahjong is over, by pressing a control button on the dice plate 1000, the dice plate 1000 moves upward to make the entry port open, and the mahjong tiles 300 can be pushed into the shuffling chamber 100 from the entry port. A shuffling tray 200 is provided in the shuffling bin 100, and the shuffling tray 200 is mainly used for processing mahjong tiles 300. The processing process includes scattering the mahjong tiles 300 in disorder and turning over the mahjong tiles 300 so that all the mahjong tiles 300 are facing up or back facing up, so as to be picked up by the card feeding component 700 provided in the shuffling bin 100 for coding.

[0040] The bottom surface of the existing shuffling bin 100 is provided with a larger shuffling plate 200, which is driven by a motor to rotate relative to the shuffling bin 100 and generate relative motion with the mahjong tiles 300, or a lever is added to the shuffling plate 200 to move the mahjong tiles 300 falling on the shuffling plate 200, which can not only scatter the mahjong tiles 300 to shuffle the tiles, but also flatten the stacked mahjong tiles 300. Magnets are arranged around the shuffling plate 200, and magnets are also arranged inside the mahjong tiles 300. When the magnetic poles of the magnets inside the mahjong tiles 300 are the same as the magnetic poles of the magnets on the shuffling plate 200, the mahjong tiles 300 will be turned over due to the repulsive force of the magnets, thereby realizing the effect of turning over the mahjong tiles 300.

[0041] In the present embodiment, at least two adjacent shuffling trays 200 are provided in the shuffling bin 100, and each shuffling tray 200 can rotate to process mahjong tiles 300 and shuffle the mahjong tiles 300. The so-called adjacent shuffling trays 200 refer to that each shuffling tray 200 is independently arranged and does not interfere with each other. In the present embodiment, the shuffling trays are distributed on the bottom surface of the shuffling bin 100, and all the shuffling trays 200 are located at the same horizontal height to ensure that each shuffling tray 200 can start processing mahjong tiles 300 at the same time. The main processing process is to ensure that all mahjong tiles 300 are facing up or back-facing up, and in addition, the stacked mahjong tiles 300 are laid flat and the mahjong tiles 300 are scattered to achieve the purpose of shuffling and making all mahjong tiles 300 face the same direction. Since the center of the shuffle bin 100 needs to be connected to the dice plate 1000 by setting a telescopic rod, if there are two shuffle discs 200, they are symmetrically distributed on both sides of the center of the shuffle bin 100, so that the mahjong tiles 300 can fall on the two shuffle discs 200 as evenly as possible; if there are three shuffle discs 200, the centers of the three shuffle discs 200 are connected to form an equilateral triangle and the center of the triangle coincides with the center of the shuffle bin 100, so that the mahjong tiles 300 can fall on the three shuffle discs 200 as evenly as possible. The best solution is to set four shuffle discs 200 of the same size in the shuffle bin 100, and the centers of the four shuffle discs 200 are respectively located at the four vertices of the square and the center of the square coincides with the center of the shuffle bin 100. In this way, the distances from the four shuffling trays 200 to the center of the shuffling bin 100 are equal, which can not only allow the mahjong tiles 300 to fall on the four shuffling trays 200 as evenly as possible, but also allow the shuffling bin 100 surrounding the outer periphery of the four shuffling trays 200 to form a square shape, which will be close to the shape of the host, that is, it can make more full use of the space under the host, and can also maximize the area of ​​the entire shuffling bin 100, thereby increasing the area where the mahjong tiles 300 are laid out. At this time, the efficiency of processing the mahjong tiles 300 will also be effectively improved, and the time for processing the mahjong tiles 300 will be reduced by 20% compared with the existing single shuffling tray 200.

[0042] The specific shuffling plate 200 includes an annular sliding surface 210 and an annular plane 220 arranged around the center of the shuffling plate 200. The annular sliding surface 210 is mainly used to guide the mahjong tiles 300 that fall onto the shuffling plate 200 to move toward the outer peripheral annular plane 220. The annular sliding surface 210 can be an inclined arc surface or a plurality of inclined planes surrounding the center of the shuffling plate 200. The height of the annular sliding surface 210 close to the center of the shuffling plate 200 is greater than the height of the annular sliding surface 210 away from the center of the shuffling plate 200, that is, the height of the annular sliding surface 210 decreases from the center to the periphery. During the rotation of the shuffling plate 200, the mahjong tiles 300 can naturally slide down along the annular sliding surface 210 with the help of gravity, so that the mahjong tiles 300 move orderly from the center to the edge of the shuffling plate 200, thereby improving the fluidity of the mahjong tiles 300 on the plate surface, which helps to improve the efficiency and smoothness of shuffling.

[0043] The annular plane 220 is connected to the bottom edge of the annular sliding surface 210, and a gap between the annular sliding surface 210 and the annular plane 220 is avoided as much as possible to cause card jamming. It is best to have a smooth transition between the annular plane 220 and the annular sliding surface 210, so that the mahjong tiles 300 can smoothly enter the annular plane 220 from the annular sliding surface 210. The annular plane 220 provides a relatively stable support plane for the mahjong tiles 300, avoiding collision or jamming of the mahjong tiles 300 due to direct falling, playing a role of buffering and transition, ensuring the stability of the shuffling process, and reducing equipment failures and noise that may be caused by the disordered movement of the mahjong tiles 300.

[0044] Furthermore, a flip magnet 120 is provided on the shuffling bin 100, and at least one flip magnet 120 is provided on the bottom surface of the shuffling bin 100 below each shuffling plate 200. The flip magnet 120 is located below the circular plane 220 of the shuffling plate 200. The flip magnet 120 is as close to the circular plane 220 as possible to maximize the magnetic absorption of mahjong tiles 300 that are not correctly flipped, but the flip magnet 120 does not contact the shuffling plate 200 to avoid hindering the normal rotation of the shuffling plate 200. According to the magnetic pole of the flip magnet 120 close to the shuffle plate 200, it can be controlled whether the mahjong tile 300 with the built-in magnet is facing up or facing up, that is, if the magnetic pole of the magnet inside the mahjong tile 300 is opposite to that of the flip magnet 120, the mahjong tile 300 will be attracted by the flip magnet 120, so that the mahjong tile 300 moves relative to the shuffle plate 200, until the mahjong tile 300 is turned over due to collision with other mahjong tiles 300 or the action of the shuffle plate 200, so as to achieve the purpose of all mahjong tiles 300 facing the same direction. When the mahjong tile 300 is attracted to turn over, it is supported by the annular plane 220. Compared with setting the flip magnet 120 at other positions, which may cause the mahjong tile 300 to be in an unstable state during the turning process, this setting method provides a more stable turning fulcrum and motion plane for the mahjong tile 300, making the turning action more stable and smooth, reducing the risk of the mahjong tile 300 affecting the shuffling process due to shaking and deviation during the turning process, and helping to improve the turning efficiency.

[0045] In order to improve the efficiency of flipping the mahjong tiles 300, a flipping paddle 230 is provided on the annular plane 220. The flipping paddle 230 rotates with the shuffling plate 200 and abuts against the mahjong tiles 300 adsorbed by the flipping magnet 120, pushing the mahjong tiles 300 to flip with the flipping paddle 230 as a fulcrum. The shape of the flipping paddle 230 is not limited, and can be a semicircular arc, a rectangle or a polygon. The height of the flipping paddle 230 is approximately 1 / 5 to 1 / 4 of the height of the mahjong tiles 300, which is more conducive to flipping the mahjong tiles 300 when the flipping paddle 230 abuts and pushes the mahjong tiles 300. The flipping paddle 230 provides a clear fulcrum and pushing direction for the flipping of the mahjong tiles 300, making the flipping process of the mahjong tiles 300 more stable and controllable, ensuring that the mahjong tiles 300 can be accurately flipped in the expected manner, improving the success rate and consistency of the flipping operation, and thus improving the shuffling quality and reliability of the automatic mahjong machine. This collaborative design makes full use of the rotational power and magnetic field of the shuffling plate 200, and realizes an efficient and stable flipping function without adding too much complex structure. Compared with some independently set and complex flipping devices, it not only simplifies the overall structure of the equipment, reduces the manufacturing cost and maintenance difficulty, but also improves the space utilization and operation stability of the equipment, so that the performance of the automatic mahjong machine is more optimized and the user experience is better.

[0046] On the basis of the above embodiment, the following schemes may be adopted for driving the shuffle plate 200 to rotate:

[0047] First, each shuffling tray 200 is connected to an independent driving motor, that is, each shuffling tray 200 is independently driven to rotate, so as to realize precise control of each shuffling tray 200, and can flexibly adjust the rotation speed, direction and other parameters of each shuffling tray 200 according to different shuffling requirements, so as to have better adaptability when facing complex shuffling tasks or special mahjong tiles 300 combinations; the driving connection mode between the driving motor and the shuffling tray 200 can adopt the driving shaft of the driving motor to directly drive the rotating shaft at the center of the shuffling tray 200 to rotate, or it can be that gear teeth 240 are arranged on the periphery of the shuffling tray 200, and the driving motor drives the shuffling tray 200 to rotate through gear transmission or chain transmission.

[0048] Second, two or more shuffle trays 200 share a driving motor to realize synchronous rotation of the shuffle trays 200. For example, in this embodiment, there are four shuffle trays 200, and two of them can be driven to rotate by a driving motor. Specifically, gear teeth 240 can also be set on the outer periphery of the shuffle tray 200, and the driving motor drives the shuffle tray 200 to rotate through gear transmission or chain transmission, such as Figure 2 Specifically, a transmission gear 500 is disposed between two adjacent shuffling trays 200 and meshes with the gear teeth 240 on the outer peripheries of the two shuffling trays 200 at the same time, and a driving motor drives the transmission gear 500 to rotate, thereby achieving simultaneous rotation of the two shuffling trays 200.

[0049] Based on the above embodiments, Figure 4 , Figure 5As shown, the shuffle tray 200 needs to withstand the impact of the falling mahjong tiles 300 and support the smooth rotation of the shuffle tray 200. Therefore, multiple groups of roller assemblies 130 supporting the rotation of the shuffle tray 200 are provided at the bottom of the shuffle bin 100. In this embodiment, eight groups of roller assemblies 130 are provided under each shuffle tray 200, and all roller assemblies 130 are evenly distributed in the same ring. The roller assembly 130 can adopt the existing public technical solution. For example, the roller assembly 130 in this embodiment includes a wheel seat and a roller rotatably arranged on the wheel seat. The wheel seat is fixed to the bottom of the shuffle bin 100. The roller is rotatably arranged on the wheel seat through a rotating shaft. The roller contacts the bottom of the shuffle bin 100 to support the shuffle bin 100 and ensure the smooth rotation of the shuffle bin 100. Compared with other supporting methods, the rolling friction coefficient between the roller and the shuffle tray 200 is smaller. This makes the resistance of the shuffle tray 200 during the rotation process significantly reduced, can run more smoothly, reduce the energy loss and component wear caused by excessive friction, is conducive to improving the operating efficiency of the equipment and extending the service life of the roller assembly 130 and the shuffle tray 200, and ensures that the automatic mahjong machine maintains stable performance during long-term use. Multiple groups of roller assemblies 130 can evenly share the weight of the shuffle tray 200, so that the shuffle tray 200 maintains a good balance state when rotating. Compared with a single-point support or a structure with fewer support points, this design effectively avoids the problems of tilting and shaking of the shuffle tray 200 caused by uneven force, ensures the smooth movement of the mahjong tiles 300 on the shuffle tray 200, reduces the collision and stacking abnormalities of the mahjong tiles 300 caused by the instability of the shuffle tray 200, thereby improving the quality and effect of shuffling, and providing players with a more reliable game experience.

[0050] Furthermore, the shuffle tray 200 is provided with an annular track 250 protruding toward the bottom of the shuffle bin 100, and the roller assembly 130 rolls along the annular track 250. The annular track 250 enables the supporting force of the roller assembly 130 on the shuffle tray 200 to be evenly distributed along the track, effectively dispersing the force on the shuffle tray 200 during the rotation process. Compared with the single-point or local force situation, this uniform force mode significantly reduces the local stress concentration, reduces the risk of deformation, wear and other damage caused by long-term uneven force on the shuffle tray 200, thereby extending the service life of the shuffle tray 200, reducing the maintenance cost and replacement frequency of the equipment, and improving the overall reliability and economy of the automatic mahjong machine. In addition, the annular track can be regarded as the reinforcing rib 270 of the shuffle tray 200, supporting the disk surface of the shuffle tray 200 and improving the overall strength of the shuffle tray 200.

[0051] In addition, the shuffle tray 200 in the present embodiment is also provided with a number of weight-reducing holes 260, which can be arranged only on the annular lower sliding surface 210 or the annular plane 220, or can be covered on both the annular lower sliding surface 210 and the annular plane 220, and the size, shape and distribution of the weight-reducing holes 260 can be selected according to the size of the shuffle tray 200 and the strength of the shuffle tray 200, and the weight-reducing holes 260 are arranged to reduce the weight of the shuffle tray 200 on the one hand, and when the automatic mahjong machine is running, the lighter shuffle tray 200 means that the energy required for the motor drive is reduced, thereby achieving energy-saving effects and reducing the operating costs of the equipment. At the same time, the reduced weight is also conducive to the stability and dynamic performance of the overall structure of the equipment, reduces unnecessary inertial loads, and improves the response speed and operating efficiency of the equipment. On the other hand, the weight-reducing holes 260 also play an important role in reducing noise. In the shuffle process, the collision between the mahjong tiles 300 and the shuffle tray 200 and the rotational vibration of the shuffle tray 200 are the main noise sources. The existence of the weight-reducing holes 260 changes the vibration mode and energy transfer path of the shuffle plate 200, and can effectively absorb and disperse the energy generated by collision and vibration, and reduce the generation and propagation of noise. Compared with the design without the weight-reducing holes 260, the noise level of the automatic mahjong machine during operation can be significantly reduced, creating a relatively quiet and comfortable gaming environment for players, improving the user experience and satisfaction, and enhancing the competitiveness of the product in the market.

[0052] There are multiple reinforcing ribs 270 radially distributed from the center of the shuffle tray 200, providing a strong support structure for the shuffle tray 200. While reducing the weight, the rigidity and deformation resistance of the shuffle tray 200 are greatly enhanced, so that it can better cope with the frequent impact and friction of the mahjong tiles 300 during the shuffle process. This structural design ensures that the shuffle tray 200 maintains good geometric shape and mechanical properties during long-term use, improves the reliability and durability of the equipment, reduces the downtime and maintenance time caused by component damage, and thus ensures the continuous and stable operation of the automatic mahjong machine.

[0053] Further, in order to enhance the strength of the entire shuffle tray 200, the reinforcing ribs 270 extend from the center of the shuffle tray 200 to the periphery, and multiple reinforcing ribs 270 are provided according to the size, material, thickness and other parameters of the shuffle tray 200, so as to ensure that the shuffle tray 200 will not be deformed when subjected to the impact of the falling mahjong tiles 300, and will not be deformed when subjected to a large number of mahjong tiles 300 piled on the shuffle tray 200, thereby ensuring that the shuffle tray 200 can operate stably for a long time. In order to simplify the structure of the shuffle tray 200, in this embodiment, the reinforcing ribs 270 are designed to be a structural form protruding from the upper surface of the shuffle tray 200, and the reinforcing ribs 270 located on the annular plane 220 form a flipping paddle, which, when encountering the mahjong tiles 300 adsorbed by the flipping magnet 120, flips the mahjong tiles 300, thereby reducing the number of components on the shuffle tray, and the reinforcing ribs 270 and the shuffle tray 200 can be integrally formed, and the strength of the reinforcing ribs 270 can also be guaranteed.

[0054] By replacing the previous arrangement of one shuffling tray 200 in the shuffling bin 100 with at least two shuffling trays 200, not only can the area of ​​the shuffling bin 100 be expanded, so that the shuffling area can be expanded and the space below the host can be fully utilized, but also the shuffling efficiency can be improved due to the expanded shuffling area, the number of mahjong tiles 300 per unit area is reduced, the probability of collision of mahjong tiles 300 is reduced, and the shuffling noise is also reduced; the reduction in the number of mahjong tiles 300 per unit area also reduces the probability of stacking of mahjong tiles 300, each shuffling tray 200 processes a relatively small amount of tiles, and the mahjong tiles 300 have more sufficient space in their respective shuffling trays 200 to roll and mix, thereby reducing the jamming caused by excessive accumulation of tiles, making the shuffling process smoother.

[0055] Embodiment 2:

[0056] like Figure 1 , Figure 6 , Figure 7As shown, on the basis of the first embodiment, in order to solve the problem of how to guide the mahjong tiles pushed into the shuffle bin through the card entry to the shuffle tray. Specifically, due to the use of at least two shuffle trays 200, there will be gaps between adjacent shuffle trays 200. If the mahjong tiles 300 fall into these gaps, they will not be processed by the shuffle trays 200. In order to fill these gaps and guide the mahjong tiles 300 that are originally going to fall into these gaps to the shuffle trays 200, a guide 400 is provided in the shuffle bin 100, and the guide 400 is arranged below the card entry, so as to better play the role of the guide 400. A guide surface 410 corresponding to each shuffle tray 200 is provided on the guide 400, that is, there are several guide surfaces 410 on the guide 400 for the number of shuffle trays 200, so as to guide the mahjong tiles 300 falling from the card entry to the corresponding shuffle trays 200. The card guide surface 410 is located between the card entry and the shuffle tray 200, and the horizontal height of the card guide surface 410 near the card entry is greater than the horizontal height of the card guide surface 410 near the shuffle tray 200, so that the mahjong tiles 300 can slide down the card guide surface 410 onto the shuffle tray 200 by their own gravity. The card guide surface 410 can be an inclined surface or a curved surface.

[0057] The mahjong tiles 300 on the shuffle tray 200 not only need to rotate with the shuffle tray 200, but also need to utilize the fact that when the mahjong tiles 300 hit the side walls around the shuffle tray 200, the mahjong tiles 300 will produce relative movement with the shuffle tray 200 due to friction with the side walls. Such relative movement can also cause the mahjong tiles 300 to be shuffled and turned over by the flip magnets 120 in the shuffle bin 100. In order to form a side wall around the shuffle tray 200, a blocking surface 110 is provided in the shuffle chamber 100. The blocking surface 110 is located at the outer periphery of the shuffle tray 200 away from the card entrance, and the guide surface 410 is located at the outer periphery of the shuffle tray 200 on the side close to the card entrance. The blocking surface 110 and the guide surface 410 together constitute the side wall of the shuffle tray 200 or form a part of the side wall. When the mahjong tiles 300 are subjected to multiple forces such as the centrifugal force of the shuffle tray 200 and its own gravity, the blocking surface 110 and the guide surface 410 can prevent the mahjong tiles 300 from sliding off the shuffle tray 200 or shifting to other areas due to the force, thereby ensuring that the mahjong tiles 300 are always shuffled within the specified range of the shuffle tray 200. A second separation ridge 111 is formed between adjacent blocking surfaces 110, and the second separation ridge 111 can prevent the mahjong tiles 300 from staying, and guide the mahjong tiles 300 to the blocking surface 110 and enter the shuffling tray 200 under the influence of the blocking surface 110. The level of the second separation ridge 111 is generally lower than the level of the shuffling tray 200, ensuring that the mahjong tiles 300 can be fully guided and preventing the mahjong tiles 300 from being stuck between the second separation ridge 111 and the shuffling tray 200.

[0058] The blocking surface 110 and the card guide 400 can be combined to form a completely closed ring, separating each shuffling tray 200 into independent areas, or the blocking surface 110 and the card guide 400 can be combined to form an open ring, so that each shuffling tray 200 is connected, and the mahjong tiles 300 can enter another adjacent shuffling tray 200 from one shuffling tray 200. Specifically:

[0059] The blocking surface 110 and the card guide 400 are enclosed into a closed ring, which separates the shuffle tray 200 independently, so that each shuffle tray 200 is in a relatively independent and stable spatial environment when working. During the shuffling process, the rotation of each shuffle tray 200 and the movement of the mahjong tiles 300 do not interfere with each other, avoiding the problems of confusion and aggravated collision of the mahjong tiles 300 that may be caused by the mutual influence between adjacent shuffle trays 200, ensuring that each shuffle tray 200 can efficiently shuffle the mahjong tiles 300 in an expected manner, thereby improving the shuffling stability and reliability of the entire automatic mahjong machine. Because it is a closed ring, the mahjong tiles 300 entering the shuffle tray 200 will also have more opportunities to be scattered and turned over.

[0060] The guide surface 410 can be extended to the blocking surface 110 and connected to the blocking surface 110, or a separator 430 can be set to connect the blocking surface 110 and the guide surface 410. Since the separator 430 only plays a blocking role, the separator 430 can be set in a detachable form to facilitate replacement after damage or deformation. When the separator 430 adopts a split structure, it can be plugged with the blocking surface 110 by setting a slot, and a convex rib can be set on the guide 400 to cooperate with the slot, or other detachable connection methods can be used to connect the separator 430 with the blocking surface 110 and the guide body; the separator 430 can also be set as a whole with the guide body, which is convenient for manufacturing and installation. The guide 400 is provided with a separator 430 that connects the corresponding blocking surface 110 and the guide surface 410, so that the guide 400, the blocking surface 110 and the guide surface 410 form an organic overall structure, and the shuffle tray 200 is better separated independently. During the frequent shuffling operation of the automatic mahjong machine, this connection structure can better withstand the impact and vibration of the mahjong tiles 300 and various stresses generated by the operation of the machine, reduce the relative displacement and looseness risks between components, thereby improving the stability and reliability of the entire structure, and ensuring the continued effectiveness of the card guiding and blocking functions during long-term use.

[0061] Furthermore, the bottom edge of the card guide surface 410 and the bottom surface of the separator 430 are both lower than the contact surface between the shuffling tray 200 and the mahjong tiles 300. Under the action of gravity, the mahjong tiles 300 can more easily slide smoothly along the card guide surface 410 to the corresponding shuffling tray 200, thereby preventing the mahjong tiles 300 from being stuck between the bottom edge of the card guide surface 410 and the shuffling tray 200, or the mahjong tiles 300 from being stuck, thereby reducing the stuck and piled-up mahjong tiles 300 caused by the bottom surface being too high, making the guiding process of the mahjong tiles 300 smoother, and helping to improve the shuffling efficiency of the entire automatic mahjong machine.

[0062] The shuffling trays 200 are connected to each other. There are at least three shuffling trays 200. The blocking surface 110 and the card guide surface 410 are combined to form a ring with a gap. The gap connects the adjacent shuffling trays 200. This connecting structure can make the mahjong tiles 300 be properly adjusted and redistributed between different shuffling trays 200 according to actual conditions. If there are too many mahjong tiles 300 in one shuffling tray 200, they can overflow from the gap to the adjacent shuffling tray 200, thereby speeding up the shuffling speed, avoiding the situation where there are too many or too few mahjong tiles 300 on some shuffling trays 200, further optimizing the distribution balance of mahjong tiles 300 on multiple shuffling trays 200, and improving the shuffling efficiency.

[0063] On the basis of the above embodiment, a first separation ridge 420 is provided between adjacent guide surfaces 410 on the guide member 400. After the mahjong tiles 300 touch the first separation ridge 420, they can quickly lean toward the guide surface 410 on one side of the first separation ridge 420, thereby accelerating the guiding speed of the mahjong tiles 300 and preventing the mahjong tiles 300 from being stuck between the two guide surfaces 410. The first separation ridge 420 can also extend toward the blocking surface 110 to form a separator 430. Furthermore, the horizontal height of the bottom end of the first separation ridge 420 is lower than the horizontal height of the shuffling tray 200, thereby preventing the mahjong tiles 300 from being stuck in the gap between the first separation ridge 420 and the shuffling tray 200.

[0064] As for the guide surface 410, the height of the guide surface 410 gradually decreases and the width gradually increases from the center of the shuffle chamber 100 to the edge of the corresponding shuffle plate 200. The height of the guide surface 410 gradually decreases and the width gradually increases from the center of the shuffle chamber 100 to the edge of the corresponding shuffle plate 200. This design conforms to the movement law of the mahjong tiles 300 under the action of gravity. The gradual decrease in height provides a natural sliding slope for the mahjong tiles 300, so that it can move relatively smoothly from the vicinity of the card entry to the shuffle plate 200; the gradual increase in width provides a wider accommodating space for the mahjong tiles 300, avoiding congestion or poor sliding of the mahjong tiles 300 due to narrow space during the guiding process. Thereby effectively improving the guiding efficiency of the mahjong tiles 300 from the card entry to the shuffle plate 200, reducing the residence time of the mahjong tiles 300 on the guide surface 410, and accelerating the shuffling process. This design enables the mahjong tiles 300 to be more evenly distributed on each shuffle plate 200. Due to the special shape of the card guide surface 410, the mahjong tiles 300 can be guided to slide down in an orderly manner, thereby avoiding the concentrated accumulation or uneven distribution of the mahjong tiles 300 in a certain area, so that each shuffling tray 200 is in a relatively balanced state when initially receiving the mahjong tiles 300. This is conducive to each shuffling tray 200 being able to operate mahjong tiles 300 of roughly the same number and distribution state during the subsequent shuffling process, thereby improving the shuffling uniformity of the entire automatic mahjong machine, improving the shuffling effect and quality, and providing a fairer game environment for players.

[0065] Furthermore, the bottom edge of the card guide surface 410 is in an arc shape and is adapted to the curvature of the outer ring of the shuffling plate 200, and the distance between the card guide surface 410 and the shuffling plate 200 is kept equal as much as possible and the gap between the card guide surface 410 and the shuffling plate 200 is matched, thereby preventing the card guide surface 410 from hindering the rotation of the shuffling plate 200. However, the gap should not be too large to prevent the mahjong tiles 300 from being stuck in the gap, ensuring that the mahjong tiles 300 can smoothly slide from the card guide surface 410 to the shuffling plate 200, maintaining the smoothness of the shuffling process, avoiding equipment failures and shuffling interruptions caused by card problems, and improving the operating stability and reliability of the automatic mahjong machine.

[0066] On the basis of the above embodiment, the shuffling trays 200 are evenly distributed on a circular track with the center of the shuffling bin 100 as the center, the card guide 400 is located at the center of the shuffling bin 100, and the card inlet is located directly above the card guide 400. This layout allows the mahjong tiles 300 to be dispersed and guided to the surrounding shuffling trays 200 in a relatively balanced manner after falling from the card inlet. Compared with a messy layout, this design makes full use of the space of the shuffling bin 100, reduces mutual interference and collision of the mahjong tiles 300 during the guiding process, improves the efficiency and uniformity of the card flow guidance, and helps to improve the overall shuffling effect.

[0067] Embodiment 3

[0068] This embodiment can be implemented on the basis of the first or second embodiment, and can also be implemented on other types of automatic mahjong machines.

[0069] like Figure 2 , Figure 8 The figure shows the third embodiment of the automatic mahjong machine of the present invention. The main body of the automatic mahjong machine of this embodiment is further provided with a ring-shaped main track 600 and at least one group of card delivery components 700 for picking up mahjong tiles 300 from the shuffling plate 200. Each group of card delivery components 700 is connected to the main track 600 through the auxiliary track 800, and the mahjong tiles 300 picked up by the card delivery components 700 are transported from the auxiliary track 800 to the main track 600. The main track 600 is provided with a conveying mechanism 610 for driving the mahjong tiles 300 to move along the main track 600. The conveying mechanism 610 drives the mahjong tiles 300 to move in the main track 600 in the same direction. When one group of card coding mechanisms is full of mahjong tiles 300, the excess mahjong tiles 300 will also be taken to the next card coding mechanism, and the mahjong tiles 300 will no longer be returned to the shuffling tray 200. Therefore, as long as the mahjong tiles 300 shuffled by the shuffling tray 200 are picked up by the card feeding component 700, the shuffling tray 200 completes the shuffling work, shortening the shuffling time and avoiding the shuffling tray 200 from running for a long time. In addition, the annular main track 600 can not only transport the mahjong tiles 300 to each group of card coding mechanisms, but also can be used as a storage component for mahjong tiles 300. When the speed of the mahjong tiles 300 sent into the main track 600 is greater than the coding speed of the card coding mechanism, the main track 600 can also take on the role of storage, ensuring that the card feeding component 700 and the shuffling tray 200 can run uninterruptedly, complete the shuffling work as soon as possible, and shorten the time when shuffling noise is generated. The specific main track 600 can be set to a circular or rounded quadrilateral to avoid forming a right angle or a corner with a small angle, so as to prevent the mahjong tiles 300 from being stuck in the main track 600. In this embodiment, the main track 600 is located above the shuffle bin 100, so as to avoid the main track 600 affecting the layout of the shuffle bin 100, and the main track 600 can be set along the edge of the shuffle bin 100, so as to extend the circumference of the main track 600 as much as possible, so that the main track 600 can carry more mahjong tiles 300.

[0070] Furthermore, the widths of the main track 600 and the secondary track 800 are adapted to the width of a single mahjong tile 300, that is, the widths of the main track 600 and the secondary track 800 are consistent with the width of a single mahjong tile 300, and can be slightly larger than the width of the mahjong tile 300, so as to ensure that the mahjong tile 300 will not be stuck in the main track 600 and the secondary track 800, and the mahjong tile 300 can smoothly move along the main track 600 and the secondary track 800. The mahjong tiles 300 will move in a row in the main track 600, which can avoid the mahjong tiles 300 being arranged in disorder horizontally and vertically in the main track 600 and the secondary track 800, so that the card coding assembly can orderly grab the mahjong tiles 300 in the main track 600.

[0071] In addition, in order to facilitate the mahjong tiles 300 on the secondary track 800 to enter the main track 600 smoothly, the angle between the conveying direction of the mahjong tiles 300 on the secondary track 800 and the conveying direction of the mahjong tiles 300 on the main track 600 is an acute angle, that is, the mahjong tiles 300 on the secondary track 800 have a component speed that moves in the direction of movement of the mahjong tiles 300 on the main track 600. After the upper mahjong tiles 300 of the secondary track 800 are partially located in the main track 600, they can also be pushed by the conveying mechanism 610 in the main track 600 to completely enter the main track 600.

[0072] A single-card passing component 900 is provided at the intersection of the main track 600 and the secondary track 800. The single-card passing component 900 controls the passage of the mahjong tiles 300 at the intersection of the main track 600 and the secondary track 800 to ensure that only the mahjong tiles 300 on the main track 600 or the secondary track 800 can pass through the intersection of the two tracks at the same time, avoiding the situation where both the main track 600 and the secondary track 800 have mahjong tiles 300 at the intersection of the two tracks, causing two mahjong tiles 300 coming from different directions to be stuck in the track.

[0073] The single card passing assembly 900 includes but is not limited to the following structural forms:

[0074] The first is a purely mechanical form. The single-card passing component 900 includes a control member 910 swingably set at the intersection of the main track 600 and the secondary track 800. When a mahjong tile 300 passes through the control member 910 on the main track 600, the control member 910 is pushed to swing toward the secondary track 800, that is, at least part of the control member 910 is located in the secondary track 800. Since the width of the secondary track 800 is equal to the width of the mahjong tile 300, the control member 910 is partially located in the secondary track 800, which will block the mahjong tile 300 in the secondary track 800 from continuing to move. The mahjong tile 300 in the secondary track 800 needs to wait until the mahjong tile 300 on the main track 600 passes before the mahjong tile 300 in the secondary track 800 can push the control member 910 away and enter the main track 600. Similarly, if the mahjong tiles 300 in the secondary track 800 reach the junction of the main track 600 and the secondary track 800 first, the mahjong tiles 300 in the secondary track 800 will push the control member 910 to swing toward the main track 600, and the control member 910 will be at least partially located in the main track 600. Similarly, the width of the main track 600 is equal to the width of the mahjong tiles 300. The partial invasion of the control member 910 into the main track 600 will block the mahjong tiles 300 in the main track 600 from continuing to move. The mahjong tiles 300 in the main track 600 can only push the control member 910 away and continue to move after the mahjong tiles 300 in the secondary track 800 enter the main track 600.

[0075] In this embodiment, the control member 910 includes a transition portion 911 and a first blocking surface 912 and a second blocking surface 913 respectively located on both sides of the transition portion 911. The entire transition portion 911 can be made into a triangular prism shape, one corner of which forms the transition portion 911, which is connected to the junction of the main track 600 and the secondary track 800 through a rotating shaft, and the rotating member is close to the upstream side of the junction of the main track 600 and the secondary track 800, so as to timely block the mahjong tiles 300 in the other track. The first blocking surface 912 blocks the mahjong tiles 300 on the main track 600 when the mahjong tiles 300 pass through the secondary track 800. 00, the second blocking surface 913 blocks the secondary track 800 when a mahjong tile 300 passes through the main track 600. Since the entire adapter 911 is in the shape of a triangular prism, the first blocking surface 912 and the second blocking surface 913 are both a side surface of the adapter 911. After the mahjong tile 300 on the main track 600 passes, the mahjong tile 300 on the secondary track 800 can slide smoothly along the second blocking surface 913, and smoothly push the control member 910 away, avoiding the control member 910 and the mahjong tile 300 on the secondary track 800 from getting stuck. Similarly, the first blocking surface 912 also has a similar effect. Since the swinging control member 910 controls the on-off of the main track 600 and the secondary track 800 in a purely mechanical way, and the control member 910 has a simple structure and high reliability, it can meet the high-speed and ordinary passage of the mahjong tile 300.

[0076] The second is to use electronic control. The single card passing component 900 includes a sensor and a blocking member controlled by the sensor. At the intersection of the main track 600 and the secondary track 800, sensors and blocking members are provided in the main track 600 and the secondary track 800. The blocking member can be in the form of linear motion, that is, the blocking member will extend into the corresponding track after being triggered, and when it is not triggered, it will be located outside the track and will not affect the movement of the mahjong tiles 300 in the track; the blocking member can also be a swinging type, that is, when the blocking member is triggered, it will rotate along the axis to enter the corresponding track, and after the mahjong tiles 300 in the other track pass through, it will swing out of the current track to allow the mahjong tiles 300 to pass through. The sensor can use a Hall sensor to sense the magnetic field of the mahjong tile 300 to identify whether the mahjong tile 300 is going to pass through the intersection of the two tracks, or it can be an infrared sensor, etc., which is triggered when the mahjong tile 300 passes through. The electronic sensor has high sensitivity, which can conveniently control the on and off of the main track 600 and the secondary track 800, and can also be linked with sensors such as counters to control the action of the blocking member while counting.

[0077] When there is only one shuffle tray 200 in the shuffle bin 100, the more groups of the card delivery assembly 700, the faster the speed of picking up mahjong tiles 300 from the shuffle tray 200 and entering the main track 600, of course, it is also necessary to consider the shuffling efficiency of the shuffle tray 200, and reasonably control the number of the card delivery assembly 700, all the card delivery assemblies 700 can be evenly distributed in the host, avoiding the mahjong tiles 300 in a certain section in the main track 600 from piling up in large quantities. When there are multiple shuffle trays 200 in the shuffle bin 100, the number of the card delivery assembly 700 is equal to the number of the shuffle tray 200, such as four shuffle trays 200 are arranged in the first embodiment, and each shuffle tray 200 corresponds to a group of card delivery assembly 700, which can ensure that the mahjong tiles 300 shuffled on each shuffle tray 200 can be picked up and enter the main track 600, even if there are too many mahjong tiles 300 on a certain shuffle tray 200, it can also ensure that all the code card assemblies can pick up a sufficient number of mahjong tiles 300 to complete the code card work. The card feeding assembly 700 and the card coding assembly in this embodiment can refer to the structure in the prior art. The card feeding assembly 700 includes a roller with a magnet, a motor for driving the rolling rotation, and a bracket for supporting the roller to roll. The roller absorbs the shuffled mahjong tiles 300 on the shuffling plate 200 through the magnet, and brings it to the secondary track 800 to be transported to the main track 600.

[0078] Based on the above embodiment, the conveying mechanism 610 includes but is not limited to the following structures:

[0079] The first is that when there are at least two groups of card delivery components 700, for example, there are four groups of card delivery components 700, which are the first, second, third and fourth groups of card delivery components in a clockwise direction, and the number of conveying mechanisms 610 is equal to the number of card delivery components 700, that is, there are four groups of conveying mechanisms 610 and they also have the same number as the card delivery components 700. The conveying mechanisms 610 extend from the card entrance of the sub-track 800 along the conveying direction of the mahjong tiles 300 on the main track 600 to the card exit of the adjacent sub-track 800, that is, the conveying mechanism 610 brings the mahjong tiles 300 from the card entrance of the first sub-track 800 into the main track 600 and conveys them to the main track 600 position at the card exit of the second sub-track 800. The four conveying mechanisms 610 arranged in this way will cover the entire main track 600 and sub-track 800, which can ensure that the mahjong tiles 300 in the sub-track 800 can smoothly enter the main track 600. The conveying mechanism 610 can use a first conveying belt or a conveying roller to ensure that the mahjong tiles 300 can move smoothly. In this embodiment, the conveying mechanism 610 uses a first conveying belt. Figure 1 , Figure 2 and Figure 4 The conveyor belt is not drawn in the figure, only the conveyor wheel driving the conveyor belt to rotate is shown.

[0080] The second is that the conveying mechanism 610 is arranged along the main track 600, that is, the conveying mechanism 610 is only responsible for moving the mahjong tiles 300 on the main track 600, and a push wheel 810 is arranged on each secondary rail, and the push wheel 810 is responsible for pushing the mahjong tiles 300 on the secondary rail into the main rail. The structure and number of the conveying mechanism 610 are not affected by the number of secondary rails 800. When adding secondary rails 800, it is only necessary to arrange push wheels 810 on the corresponding secondary rails 800, and the arrangement is more flexible. The conveying mechanism 610 can also adopt the structure of a second conveyor belt or a conveyor roller.

[0081] Through the structure of the automatic mahjong machine, the shuffling plate 200 only needs to shuffle the mahjong tiles 300 once, and will not accept the mahjong tiles 300 returned from the card coding assembly, which can shorten the operation time of the shuffling plate 200, thereby reducing the time of noise generation during shuffling, and improving the user experience. In addition, in this embodiment, a circular main track 600 is used, and the mahjong tiles 300 will move in the circular main track 600 until they are picked up by the card coding assembly, which can not only transport the mahjong tiles 300 to each group of card coding mechanisms, but also can be used as a storage component for mahjong tiles 300, so that the shuffling plate 200, the card delivery assembly 700 and the card coding assembly are not restricted by each other and can run at their respective optimal speeds to complete their respective tasks as soon as possible.

[0082] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
