Description

Technical Field

[0001] This invention relates to a mahjong machine, and more particularly to a mahjong machine card-collecting component and a mahjong machine including the card-collecting component. Background Technology

[0002] A mahjong machine is an entertainment device that can automatically shuffle and stack mahjong tiles. Its core technology utilizes magnetic mahjong tiles in conjunction with a mechanical structure to achieve automation.

[0003] An existing mahjong machine, such as the mahjong machine shuffling method disclosed in the Chinese Patent Database (CN111744166B), includes the following steps: when only 1 to 5 mahjong tiles remain on the shuffling plate, the shuffling plate pauses at least once after each rotation. During the pause, the suction wheel operates normally until all mahjong tiles are sucked up. The top surface of the shuffling plate is provided with at least one radially extending rib. When the shuffling plate pauses rotation, the rib is directly below the suction wheel. The shuffling plate is driven by a drive unit, which is controlled by a control unit. The control unit includes a control module and a signal acquisition component connected to the control module. When the signal acquisition component detects that the rib on the shuffling plate has reached the predetermined suction wheel, the signal acquisition component sends a plate pause signal to the control module. The control module receives the plate pause signal and controls the drive unit and the shuffling plate to pause operation according to the plate pause signal.

[0004] The aforementioned mahjong machine has two problems: 1. In current products, the shuffling disc usually contacts the mahjong tiles through a rough surface. When the shuffling disc stops running, the mahjong tiles can only slide a short distance under the action of inertial centrifugal force. This results in the situation where the mahjong tiles are not moved to the ribs, causing the shuffling disc to need to rotate again for the suction wheels to pick up the mahjong tiles, affecting the tile-loading efficiency; 2. Because the suction surfaces on the suction wheels are distributed in multiple segments at circumferential intervals, there are instances where the front suction wheels pick up mahjong tiles that should be picked up by the rear suction wheels. In this case, the shuffling disc needs to rotate and knock the picked-up mahjong tiles off through the mahjong tiles or ribs on the shuffling disc. This not only further affects the tile-loading efficiency, but also generates significant noise from the collision, affecting the user experience of the mahjong machine. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a mahjong machine card-collecting component and a mahjong machine that can improve card-playing efficiency.

[0006] One objective of this invention can be achieved through the following technical solution: a mahjong machine card suction assembly, the mahjong machine including a controller, a shuffling tray, a counter, a card storage tray and a conveyor frame fixed at the inlet of the card storage tray, the counter communicating with the controller and used to count the mahjong cards entering the card storage tray through the inlet; This card-collecting assembly includes a card-collecting wheel horizontally rotatably mounted on a conveyor frame and a card-collecting motor for driving the wheel's rotation. The card-collecting wheel is positioned directly above the shuffling tray. The side of the card-collecting wheel includes a circumferentially spaced surface for collecting mahjong tiles. The assembly is characterized by further including a position sensing module and a control component. The position sensing module is set on the conveyor and is used to sense the mahjong tiles on the shuffling tray. The position sensing module is set close to the suction wheel and the two are distributed in sequence along the rotation direction of the shuffling tray. The control components include a trigger element fixed on the card-collecting wheel and a sensing element fixed on the conveyor frame and cooperating with the trigger element; Both the sensing element and the position sensing module communicate with the controller; When there are only 1 to 5 mahjong tiles left on the shuffling plate and the position sensing module detects the mahjong tiles, the controller stops the shuffling plate from rotating. After the counter reaches the set value and the sensor detects the trigger element, the controller pauses the operation of the card suction motor. At this time, each card suction surface is not facing the shuffling plate.

[0007] When in use, when there are only 1 to 5 mahjong tiles left on the shuffling plate, as the shuffling plate rotates, when the position sensing module senses the mahjong tile, the position sensing module sends a shuffling plate pause signal to the controller. After receiving the shuffling plate pause signal, the controller controls the shuffling plate to stop rotating. At this time, the mahjong tile sensed by the position sensing module moves to the bottom of the suction wheel under the action of inertial centrifugal force, and the suction wheel is used to attract the mahjong tile. When the counter reaches the set value (i.e., the card storage tray is full) and the sensing element detects the trigger element, both the counter and the sensing element send signals to the controller. After receiving the signals from the counter and the sensing element, the controller stops the card suction motor from rotating. At this time, each card suction surface is not facing the shuffling tray to prevent the card suction wheel from continuing to suction mahjong tiles while the shuffling tray is rotating.

[0008] Since the inertial sliding stroke of the mahjong tiles fluctuates within a small range when the shuffling plate is paused, the position sensing module directly senses the position of the mahjong tiles to control the shuffling plate to pause its rotation. This ensures that the mahjong plate can accurately slide to the suction wheel's adsorption area when the shuffling plate is paused, allowing the suction wheel to adsorb the mahjong tiles in one go, effectively improving the efficiency of tile loading. Secondly, after the suction wheel stops rotating, the suction surfaces on the suction wheel do not face the shuffling plate. This way, the suction wheel will not be sucking up mahjong tiles when the shuffling plate is running. This not only avoids mutual interference between the different tile-feeding positions of the mahjong machine, thus further improving the tile-feeding efficiency, but also avoids the situation where mahjong tiles left on the shuffling plate collide with the mahjong tiles sucked on the suction wheel, effectively reducing the noise of the mahjong machine during operation.

[0009] In the aforementioned mahjong machine card-collecting assembly, the position sensing module is a non-contact position switch, which has advantages such as simple structure and stable operation.

[0010] In the aforementioned mahjong machine card-collecting assembly, the card-collecting wheel includes a main body made of non-magnetic material, the triggering element is a magnet, and the magnet is fixed on one end of the main body near the conveyor frame. The sensing element includes a circuit board fixed on the conveyor frame and a Hall element mounted on the circuit board, so as to sense the position of the magnet through the Hall element and thereby control the rotation angle of the card-collecting wheel. It has the advantages of simple structure and stable operation.

[0011] In the aforementioned mahjong machine card-collecting assembly, the number of magnets and card-collecting surfaces are the same, and the magnets and card-collecting surfaces are alternately distributed along the circumference of the card-collecting wheel. This increases the speed at which the Hall element senses the magnet, effectively preventing the card-collecting wheel from adhering to mahjong tiles during the sensing process, and making the goal of reducing the noise of the mahjong machine during operation more stable.

[0012] In the aforementioned mahjong machine card-collecting assembly, the end face of the main body near the conveyor frame has a socket with a shape and size that matches the magnet, and the axes of the socket and the main body are arranged parallel to each other; the number of sockets and magnets is the same, and each magnet is embedded in the corresponding socket, which has the advantages of simple structure and convenient assembly.

[0013] In the aforementioned mahjong machine card-collecting assembly, the card-collecting motor is mounted on the conveyor frame and located on the side of the card-collecting wheel. The card-collecting motor and the main body are connected by a gear pair to free up the position of the conveyor frame directly facing the main body, which facilitates the design and installation of the circuit board.

[0014] In the aforementioned mahjong machine card-collecting assembly, the gear pair includes a driven gear integrally formed on the end face of the main body, and the driven gear is located between the main body and the conveyor frame.

[0015] In the aforementioned mahjong machine card-collecting assembly, the main body has a number of connecting tubes that are the same as the number of magnets vertically formed on the end face near the conveyor frame, and the inner hole of the connecting tube is the aforementioned insertion hole.

[0016] In the aforementioned mahjong machine card-collecting assembly, a ring of ribs is vertically formed on the end face of the main body near the conveyor frame. The length of the ribs extends radially along the driven gear, and one end of the ribs extends to the inner wall of the driven gear. The number of ribs and connecting pipes are the same and their positions correspond one-to-one. Each connecting pipe cuts the corresponding rib into two segments distributed radially along the driven gear to strengthen the structural strength of the connecting pipe.

[0017] As another option, in the mahjong machine card-collecting assembly described above, the triggering element is a detection rod, and the detection rod is vertically fixed on the end face of the card-collecting wheel near the conveyor frame; the sensing element is a slotted switch fixed on the conveyor frame.

[0018] Another objective of the present invention can be achieved by the following technical solution: a mahjong machine, comprising a shuffling plate and four card storage plates distributed around the shuffling plate, wherein a conveyor frame is fixed at the inlet of each card storage plate, characterized in that each conveyor frame is provided with the aforementioned card suction component.

[0019] Compared with existing technologies, this mahjong machine's tile-collecting component and mahjong machine have the following advantages: 1. Since the inertial sliding stroke of the mahjong tiles fluctuates within a small range when the shuffling plate is paused, the position sensing module directly senses the position of the mahjong tiles to control the shuffling plate to pause its rotation. This ensures that the mahjong plate can accurately slide to the suction wheel's adsorption area when the shuffling plate is paused, allowing the suction wheel to adsorb the mahjong tiles in one go, effectively improving the efficiency of tile loading. 2. After the suction wheel stops rotating, the suction surfaces on the suction wheel are not facing the shuffling plate. This way, the suction wheel will not be sucking up mahjong tiles when the shuffling plate is running. This not only avoids mutual interference between the different tile-feeding positions of the mahjong machine, thus further improving the tile-feeding efficiency, but also avoids the situation where mahjong tiles left on the shuffling plate collide with the mahjong tiles sucked on the suction wheel, effectively reducing the noise of the mahjong machine during operation.

Detailed Implementation

[0026] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0027] Example 1: As Figure 1 As shown, in the mahjong machine's card-collecting assembly and the mahjong machine itself, the mahjong machine includes a controller, a shuffling tray 1, a counter 3, a card storage tray 4, and a conveyor frame 5 fixed at the inlet 4a of the card storage tray 4. Among these components... The shuffling disk 1 is horizontally positioned and is driven by the shuffling motor 2 to rotate around its central axis. The shuffling motor 2 is a servo motor, which is electrically connected to the controller via wires so that the controller can control the shuffling motor 2 to start or stop.

[0028] The card storage tray 4 is located above the outer periphery of the shuffling tray 1, and the card storage tray 4 has an inlet 4a for inputting mahjong tiles into it.

[0029] The conveyor frame 5 is fixed at the inlet 4a of the storage plate 4.

[0030] Counter 3 is fixed on the tile storage tray 4. Counter 3 communicates with the controller and is used to count the mahjong tiles entering the tile storage tray 4 through inlet 4a. In the actual product, counter 3 is electrically connected to the controller via wires, making the signal transmission between counter 3 and the controller more stable.

[0031] In the actual product of the mahjong machine, there are four card storage trays 4, which are distributed around the shuffling tray 1. At this time, the four card storage trays 4 are distributed around the shuffling tray 1. The number of conveyor racks 5, counters 3 and card suction components are four, and their positions correspond one-to-one with the card storage trays 4.

[0032] Specifically like Figure 2 and Figure 3 As shown, the card suction assembly includes a card suction wheel 6 that is horizontally rotatably mounted on the conveyor frame 5, a card suction motor 11 for driving the card suction wheel 6 to rotate, a position sensing module 12, and a control component.

[0033] The card-collecting wheel 6 is positioned directly above the shuffling plate 1. The side of the card-collecting wheel 6 includes a ring of evenly spaced suction surfaces 6a for collecting mahjong tiles. The card-collecting wheel 6 is rotatably mounted on the conveyor frame 5 via a connecting shaft, with the shaft and wheel 6 coaxially aligned. Specifically, the card-collecting wheel 6 has a central hole extending axially through it. One end of the shaft extends into the central hole and is fixedly connected to the card-collecting wheel 6. The conveyor frame 5 has a mounting hole that matches the connecting shaft, and the other end of the connecting shaft is pivotally connected to the mounting hole.

[0034] like Figure 4 and Figure 5As shown, the structure of the card-collecting wheel 6 is as follows: The card-collecting wheel 6 includes a main body 6b made of a non-magnetic material, and the aforementioned central hole is located on the main body 6b. The non-magnetic material can be ceramic or plastic, and the main body 6b is usually made of plastic. The side of the main body 6b consists of several flat surfaces and several arc surfaces 6b1. The arc surfaces 6b1 are coaxially arranged with the main body 6b, and the number of flat surfaces and arc surfaces 6b1 are the same and they are continuously and alternately distributed along the circumference of the main body 6b. Each flat surface has a mounting groove, and a magnetic block is fixed in the mounting groove. The side of the magnetic block away from the bottom wall of the mounting groove is flush with the corresponding flat surface, and the side of the magnetic block away from the bottom wall of the mounting groove is the aforementioned card-collecting surface 6a. In actual products, the number of card-collecting surfaces 6a is three, that is, the number of arc surfaces 6b1 and flat surfaces is three. Of course, the number of card-collecting surfaces 6a can also be adjusted to other numbers, such as two, four, etc., and this design is mainly determined by the diameter of the card-collecting wheel 6.

[0035] The card-collecting motor 11 is a servo motor, and it is electrically connected to a controller via wires so that the controller can control the start or stop of the card-collecting motor 11. Figures 3 to 5 As shown, the card-collecting motor 11 is mounted on the conveyor frame 5 and drives the card-collecting wheel 6 to rotate. Specifically, the card-collecting motor 11 is located on the side of the card-collecting wheel 6, and the card-collecting motor 11 and the main body 6b are connected by a gear pair. The gear pair includes a driving gear 7 fixed on the main shaft of the card-collecting motor 11 and a driven gear 6b2 integrally formed on the end face of the main body 6b. The driven gear 6b2 is located between the main body 6b and the conveyor frame 5, and the driving gear 7 and the driven gear 6b2 mesh with each other.

[0036] A position sensing module 12 is mounted on the conveyor frame 5 and is used to sense the mahjong tiles on the shuffling tray 1. The position sensing module 12 is positioned close to the tile-absorbing wheel 6, and both are distributed sequentially along the rotation direction of the shuffling tray 1. The position sensing module 12 is a non-contact position switch. The position sensing module 12 communicates with the controller, and in the actual product, the position sensing module 12 is electrically connected to the controller via a wire. The non-contact position switch can be a photoelectric switch, a contact switch, etc., and preferably a photoelectric switch.

[0037] The control assembly includes a trigger element fixed to the card-collecting wheel 6 and a sensing element fixed to the conveyor frame 5 and cooperating with the trigger element. The sensing element communicates with the controller.

[0038] When there are only 1 to 5 mahjong tiles left on the shuffling plate 1 and the position sensing module 12 senses the mahjong tiles, the controller stops the rotation of the shuffling plate 1; after the counter 3 counts to the set value and the sensing element senses the trigger element, the controller stops the operation of the card suction motor 11. At this time, each card suction surface 6a is not facing the shuffling plate 1.

[0039] In use, when only 1 to 5 mahjong tiles remain on the shuffling plate 1, as the shuffling plate 1 rotates, when the position sensing module 12 detects a mahjong tile, the position sensing module 12 sends a pause signal to the controller. Upon receiving the pause signal, the controller stops the rotation of the shuffling plate 1. At this time, the mahjong tile detected by the position sensing module 12 moves to below the suction wheel 6 under the action of inertial centrifugal force, and is then attracted to the tile by the rotation of the suction wheel 6. In other words, the controller will only stop the rotation of the shuffling plate 1 when both 1 to 5 mahjong tiles remain on the shuffling plate 1 and the position sensing module 12 detects a mahjong tile.

[0040] The remaining number of mahjong tiles on the shuffle plate 1 can be calculated using the following formula: Remaining number of mahjong tiles = Total number of mahjong tiles - Number of mahjong tiles calculated by the four counters 3, and this calculation formula is stored in the controller.

[0041] When counter 3 counts to the set value (i.e., the card storage tray 4 is full) and the sensing element detects the trigger element, both counter 3 and the sensing element send signals to the controller. Upon receiving the signals from counter 3 and the sensing element, the controller pauses the card suction motor 11. At this time, each card suction surface 6a is not facing the shuffling tray 1 to prevent the card suction wheel 6 from continuing to suction mahjong tiles while the shuffling tray 1 is rotating. In other words, the controller will only stop the shuffling motor 2 when both the counter 3 counts to the set value and the sensing element detects the trigger element.

[0042] Since the inertial sliding stroke of the mahjong tiles fluctuates within a small range when the shuffling plate 1 is paused, the position sensing module 12 directly senses the position of the mahjong tiles to control the shuffling plate 1 to pause its rotation. This ensures that the mahjong plate can accurately slide to the suction wheel 6's adsorption area when the shuffling plate 1 is paused, so that the suction wheel 6 can adsorb the mahjong tiles in one go, effectively improving the efficiency of playing the tiles. Secondly, after the suction wheel 6 stops rotating, the suction surfaces 6a on the suction wheel 6 do not face the shuffling plate 1. In this way, the suction wheel 6 will not be adsorbing mahjong tiles when the shuffling plate 1 is running. This not only avoids mutual interference between the four tile-feeding positions of the mahjong machine, thus further improving the tile-feeding efficiency, but also avoids the situation where mahjong tiles left on the shuffling plate 1 collide with mahjong tiles adsorbed on the suction wheel 6, effectively reducing the noise of the mahjong machine during operation.

[0043] In this embodiment, like Figure 4 and Figure 5As shown, the triggering element is a magnet 8, which is fixed to one end of the main body 6b near the conveyor frame 5. The sensing element includes a circuit board 9 fixed to the conveyor frame 5 and a Hall element 10 mounted on the circuit board 9. The Hall element 10 senses the position of the magnet 8 to control the rotation angle of the card-collecting wheel 6, which has the advantages of simple structure and stable operation. The Hall element 10 is mounted on the side of the circuit board 9 near the card-collecting wheel 6. The circuit board 9 is electrically connected to the controller via wires. The conveyor frame 5 has a clearance opening that runs through the axial direction of the card-collecting wheel 6. The clearance opening is positioned directly opposite the Hall element 10 so that the side of the conveyor frame 5 facing the magnet 8 is unobstructed.

[0044] To further explain, the number of magnets 8 and the number of card-absorbing surfaces 6a are the same, and the magnets 8 and the card-absorbing surfaces 6a are alternately distributed along the circumference of the card-absorbing wheel 6 to increase the speed at which the Hall element 10 senses the magnets 8, effectively preventing the card-absorbing wheel 6 from adhering to mahjong tiles during the sensing process, and making the goal of reducing the noise of the mahjong machine during operation more stable.

[0045] like Figure 5 As shown, the magnet 8 is installed as follows: The end face of the main body 6b near the conveyor frame 5 has insertion holes 6d, the shape and size of which match the magnet 8, and the axes of the insertion holes 6d and the main body 6b are parallel. The number of insertion holes 6d and magnets 8 is the same, and each magnet 8 is embedded in its corresponding insertion hole 6d, which has the advantages of simple structure and convenient assembly. Further, the end face of the main body 6b near the conveyor frame 5 has vertically formed connecting tubes 6c, the same number as the magnets 8, and the inner hole of the connecting tubes 6c is the aforementioned insertion hole 6d.

[0046] In the actual product, a ring of ribs 6e is vertically formed on the end face of the main body 6b near the conveyor frame 5. The length of the ribs 6e extends radially along the driven gear 6b2, and one end of the ribs 6e extends to the inner wall of the driven gear 6b2. The number of ribs 6e and the positions of the connecting pipes 6c are the same and correspond one-to-one. Each connecting pipe 6c cuts the corresponding rib 6e into two segments distributed radially along the driven gear 6b2 to strengthen the structural strength of the connecting pipe 6c.

[0047] Example 2: The structure and principle of Example 2 are basically the same as those of Example 1. The difference is that the triggering element is a detection rod, and the detection rod is vertically fixed on the end face of the card suction wheel 6 near the conveyor frame 5; the sensing element is a slotted position switch fixed on the conveyor frame 5.

[0048] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
