Description

Technical Field

[0001] The invention belongs to the field of mahjong machine entertainment equipment, relates to a mahjong machine, and in particular to a card pushing device for pushing mahjong tiles from the inside of the mahjong machine to the table thereof, and a card loading mechanism containing the card pushing device and a mahjong machine. Background Art

[0002] A mahjong machine is a device that can avoid the user's shuffling and sorting operations and facilitate the game. It usually has a shuffling mechanism for shuffling mahjong tiles, a loading mechanism for stacking the shuffled cards and placing them on the table for use, an operating disk mechanism for the user to input operating instructions, and a table frame for overall support.

[0003] Among them, the card-loading mechanism needs to be set up corresponding to each user. For example, a common mahjong machine is used by four users, and four sets of corresponding card-loading mechanisms need to be set up; each set of card-loading mechanisms also needs to realize functions such as stacking cards, storing cards, pushing cards, and raising cards, and the size of the desktop should not be too large. Therefore, the layout space of the card-loading mechanism is relatively limited, and the structural design needs to be very compact.

[0004] In some prior arts, a card loading mechanism is provided with an annular card slot for temporarily storing card piles and a card pushing device for pushing the card piles in the card slot to the card outlet. For example, CN111991798A discloses a fully automatic mahjong machine, wherein the card pushing device comprises a driving motor, a card pushing gear (card dragging gear), a driven gear, and a telescopic arm, wherein the driving motor drives the card pushing gear and the driven gear to rotate, thereby driving the telescopic arm to rotate, and the front end of the telescopic arm moves in the card slot to push the cards. In such a structure, the telescopic arm relies on intermittent motor drive to achieve circumferential rotation. It is difficult to determine the current status of the telescopic arm and the motor, the specific position of the card-pushing front end of the telescopic arm, and whether it will interfere with other components in the card-loading mechanism. Therefore, the entire card-pushing action cannot provide accurate feedback information, which is not conducive to the accurate control of the card-pushing action and the precise coordination of other actions such as stacking and loading cards with the card-pushing action. The telescopic arm may interfere with the card stacking device at the card entrance of the card slot, resulting in insufficient stacking of cards, or the telescopic arm may not cooperate well with the card lifting device, resulting in some mahjong tiles not being lifted onto the table and remaining in the card slot. In other words, accurate automatic card-pushing action control cannot be achieved, which affects the progress of the game.

[0005] In particular, if the user wishes to use different card loading modes, such as loading cards at one time, or loading cards for the starting hand and cards to be taken twice, the card pushing action needs to be performed at the corresponding time according to the different modes, and the card pushing and card pushing should be started and stopped at the precise time point, and should be more accurately coordinated with other action mechanisms to avoid mutual interference. The card pushing device in the prior art lacks a feedback mechanism, so it is impossible to properly set the timing of the card pushing action, and it is also impossible to set the coordination of other action mechanisms according to the current card pushing state, that is, it is impossible to achieve the above-mentioned different card loading modes.

[0050] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the card pushing device, card loading mechanism and mahjong machine of the present invention are specifically described below in combination with embodiments and drawings.

[0051] <Example>

[0052] Figure 1 It is a block diagram of the mahjong machine in this embodiment. Figure 2 This is a structural diagram of the mahjong machine at one angle in this embodiment. Figure 3 It is a structural diagram of the mahjong machine from another angle in this embodiment.

[0053] like Figures 1 to 3 As shown, this embodiment provides a mahjong machine 100 for automatically shuffling and loading mahjong tiles 200, including a shuffling mechanism 107, four loading mechanisms 101, an operating disk mechanism 102, a table frame mechanism 103 and a control device 108.

[0054] The table frame mechanism 103 includes an outer frame 104, a table top 105 installed on the outer frame 104, and a lower frame 106 for supporting the table top 105 and other mechanisms. The bottom of the lower frame 106 is provided with table legs for supporting on the ground.

[0055] The operation panel mechanism 102 is arranged in the middle of the table top 105, and an operation panel 1021 is arranged on the top thereof. The operation panel 1021 is provided with a plurality of different operation buttons (not shown in the figure) for the user to input operation instructions. In this embodiment, the mahjong machine supports two play modes, and the user can set which play mode to use on the operation panel 1021. The control device 108 obtains the corresponding operation instruction and sends the signal for setting the corresponding play mode to each card loading mechanism 101.

[0056] In this embodiment, the operating disk mechanism 102 is also provided with a lifting assembly, which can lower the operating disk 1021 under the control of the control device 108 to expose the gap between the operating disk 1021 and the table top 105. At this time, the user can push the used mahjong tiles 200 into the gap to shuffle the cards.

[0057] The shuffling mechanism 107 is disposed below the operating panel 1021, and is used to receive used mahjong tiles 200 and shuffle them. It includes a shuffling plate for carrying and rotating the mahjong tiles and a driving motor for driving the shuffling plate to rotate. Its specific structure and function are the same as those of the prior art and will not be described in detail herein.

[0058] The mahjong machine 100 of this embodiment can be used by four users at the same time, and accordingly, four card loading mechanisms 101 are provided, which are respectively located at the four corners of the lower frame 106 .

[0059] The control device 108 is used to control the operation of each component of the mahjong machine 100 according to the operation instructions input by the user. The control device 108 can be a chip or an industrial computer or a microcomputer with a predetermined control program, and is connected to the operation panel mechanism 102 and each controlled component and sensor of the mahjong machine 100. In addition, in this embodiment, each of the control units described below can be integrated in the control device 108, or can be a separate control program set in another chip, which is electrically connected or communicatively connected to the control device 108.

[0060] Figure 4 This is a structural diagram of the card loading mechanism at one angle in this embodiment. Figure 5 It is a structural diagram of the card loading mechanism from another angle in this embodiment.

[0061] like Figure 4 and Figure 5 As shown, the card loading mechanism 101 includes a card supply device 10, a card stacking device 20, a card storage device 30, a card pushing device 40 and a card raising device 50. Among them, the card stacking device 20, the card pushing device 40 and the card raising device 50 respectively include corresponding hardware structures and respective control units. The hardware structures will be described first, and then the control units will be described in combination with the hardware structures.

[0062] Figure 6 It is a structural diagram of the card supply device in this embodiment.

[0063] like Figures 4 to 6 As shown, the card supply device 10 includes a card suction wheel 11 , a card supply rack 12 , a belt assembly 13 and a card supply motor 14 .

[0064] Among them, the card supply rack 12 is fixedly installed on the lower frame 106, located near the shuffling mechanism 101, and has an opening facing the shuffling plate of the shuffling mechanism 101. The card suction wheel 11 is rotatably installed at the opening, and the output end of the card supply motor 14 is connected to the card suction wheel 11, which can drive the card suction wheel 11 to rotate.

[0065] The belt assembly 13 includes a card supply belt 15 wound around the card suction wheel 11, a guide wheel 16 for guiding the card supply belt 15, and a tensioning wheel 17 for tensioning the card supply belt 15. The guide wheel 16 is installed near the card stacking device 20 so that the card supply belt 15 can transport the mahjong cards thereon to the card stacking device 20.

[0066] In this embodiment, a plurality of card-attracting magnets are installed on the card-attracting wheel 11, and the mahjong tiles 200 are all inlaid with magnetic materials that can be mutually attracted to the shuffling magnets. When the card-attracting wheel 11 rotates under the drive of the card-supplying motor 14, the card-attracting magnets rotated to the downward position can absorb the mahjong tiles 200 below, and the mahjong tiles 200 are driven to the top of the card-attracting wheel 11 as the card-attracting wheel 11 continues to rotate, and then are transported to the stacking device 20 by the card-supplying belt 15.

[0067] Figure 7 : is a structural diagram of the card stacking device in this embodiment, Figure 8 : is a structural diagram of a partial structure of the card stacking device in this embodiment, Figure 8 The stacking housing and the stacking motor are omitted in order to show other internal structures.

[0068] like Figures 4 to 8 As shown, the stacking device 20 is used to stack the single mahjong tiles delivered by the card supply device 10 to form a pile of tiles with two tiles stacked together, and includes a stacking unit and a card shifting unit.

[0069] The stacking unit includes a stacking block 21, a stacking block driving rod 22, a stacking driving wheel 23 and a stacking motor 24, and the card shifting unit includes a card shifting block 25, a card shifting connecting rod 26 and a card shifting driving block 27. In addition, the stacking device 20 also has a stacking housing 28 for accommodating and supporting the stacking unit and the components in the card shifting unit.

[0070] The top of the stacking block 21 is a plane, which is located near the guide wheel 16 of the card supply belt 15 in the initial state and can receive the mahjong tiles transported by the card supply belt 15 .

[0071] A stacking block slot 211 is provided on the stacking block 21 , and one end of the stacking block driving rod 22 is a movable end, which is slidably engaged in the stacking block slot 211 through a slider.

[0072] The card stacking driving wheel 23 is mounted on the output shaft of the card stacking motor 24 and rotates under the drive of the card stacking motor 24 . A card stacking driving groove 231 is provided on one side surface of the card stacking driving wheel 23 .

When the stacking drive wheel 23 rotates, the stacking block driving rod 22 swings up and down, driving the stacking block 21 to move up and down through the movable end.

[0074] Fig. 9 It is a structural diagram of one side of a card stacking block according to an embodiment of the present invention.

[0075] like Fig. 9 As shown, the stacking driving groove 231 is approximately annular in shape, and has an inner concave section 231A with a reduced radius and an outer convex section 231B with an increased radius. When the slider in the middle of the stacking block driving rod 22 is in the inner concave section 231A, the top plane of the stacking block 21 is lower than the upper plane of the end of the card supply belt 15, and the height difference is slightly greater than the thickness of two mahjong tiles, so that the mahjong tiles transported by the card supply belt 15 can be stacked and fall on the top plane of the stacking block 21; when the slider in the middle of the stacking block driving rod 22 runs to the outer convex section 231B, it can drive the stacking block 21 to move slightly upward as a whole, so that the card shifting block 25 can perform the card shifting action.

[0076] The card-playing block 25 is fixed on the top of the card-playing connecting rod 26. The card-playing connecting rod 26 is bent in an approximately L-shaped shape, and its lower end is fixed on a side of the card-playing driving block 27.

[0077] Fig.10 4 is a structural diagram of a shift block driving block according to an embodiment of the present invention.

[0078] like Fig.10 As shown, an arc-shaped card-digging slot 271 is provided on the other side of the card-digging driving block 27, and a slider slidably engaged in the card-digging slot 271 is provided on the other side of the card-stacking driving wheel 23 (i.e., the side opposite to the side where the card-stacking block slot 211 is located); as the card-stacking driving wheel 23 rotates, under the action of the slider and the card-digging slot 271, the card-digging driving block 27 intermittently moves back and forth and drives the card-digging block 25 to move back and forth through the card-digging connecting rod 26, so that when the two mahjong tiles 200 on the top of the card-stacking block 21 overlap to form a tile pile, the tile pile is moved toward the card storage device 30.

[0079] Fig.11It is a structural diagram of the card storage device in this embodiment.

[0080] like Fig.11 As shown, the card storage device 30 includes a card storage tray 31 and an upper slot plate 32, a lower slot plate 33 and an inner slot plate 34.

[0081] The card storage tray 31 is in a generally square shape, with one corner being notched and the other three corners being arc-shaped, with a retaining wall 311 extending vertically upward at the edge, and a central portion bulging upward, so that a card slot 312 is formed between the retaining wall 311 and the central portion bulging. In addition, a support 313 is further provided at the bottom of the card storage tray 31, and the tray is mounted on the lower frame 106 through the support 313.

[0082] The upper slot plate 32 is a plate-like component that matches the shape of the baffle wall 311 and is embedded in the upper inner surface of the baffle wall 311; the lower slot plate 33 is a plate-like component that matches the card slot 312 and is embedded in the bottom surface of the card slot 312; the inner slot plate 34 is approximately annular and is adapted to the middle protrusion of the card storage tray 31, and is installed on the outer edge of the middle protrusion of the card storage tray 31.

[0083] The card supply device 10 and the card stacking device 20 are located at the corner of the notch of the card storage tray 31 and are arranged near one end of the card slot 312, the one end of the card slot 312 being the card inlet 312C and the other end being the card outlet 312D. The card stacking block 21 is located at the end opening of the card slot 312. When the card block 25 is used to push the card pile toward the card storage device 30, the card pile will enter the card slot from the end opening of the card slot 312; when the next card pile is stacked and pushed toward the card slot 312 by the card block 25, the card pile will also push the card pile that has entered the card slot 312, and so on and so forth, so that a certain number of card piles can be stored in the card slot 312.

[0084] Fig.12 It is a cross-sectional structural diagram of the card slot in this embodiment.

[0085] like Fig.12As shown, the upper slot plate 32, the lower slot plate 33 and the inner slot plate 34 are all adapted to the card slot 312, and together form a card storage slot structure that can store card piles and allow card piles to pass. Among them, the bottom end of the upper slot plate 32 has a flange 321 protruding toward the center direction of the card slot 312, and the upper half of the inner slot plate 34 protrudes outward, so that two upper and lower parts with different movement radii (i.e., distances relative to the center of the card storage plate 31) are formed in the card slot 312 (as shown by the two dotted boxes in the figure), namely, the upper card slot 312A and the lower card slot 312B. The upper card slot 312A and the lower card slot 312B correspond to the upper and lower mahjong tiles in the tile pile respectively. Since the movement radius of the upper card slot 312A is larger, even if the upper mahjong tile moves faster because the lower surface only contacts the lower mahjong tile, resulting in less friction during movement, the upper card slot 312A can also provide a slightly longer movement path, so that the upper mahjong tile will not separate from the lower mahjong tile due to the faster speed when moving in the slot.

[0086] Fig.13 : is a structural diagram of the card pushing device at one angle in this embodiment. Fig.14 It is a structural diagram of the card pushing device from another angle in this embodiment.

[0087] like Fig.13 and Fig.14 As shown, the card pushing device 40 includes a card pushing seat 41, a card pushing rotating seat 42, a card pushing arm 43, a card pushing motor 44, a card pushing driving gear 45, and a card pushing sensing unit 46.

[0088] The card pusher 41 is fixedly mounted in the middle of the card storage tray 31, that is, located in the inner circle of the card slot 312, with a circular notch 41A in the middle and a circle of rotating grooves 411 around the periphery. The shape and contour of the rotating groove 411 are basically matched with the upper card slot 312A, but the size is smaller, and there is a concave section 412 near the notch of the card storage tray 31.

[0089] The card pushing rotating seat 42 is rotatably mounted on the card storage tray 31 via a rotating shaft 310, and is entirely located in the notch 41A, with the upper surface exposed from the notch 41A. A push arm mounting protrusion 421 is provided on the upper surface of the card pushing rotating seat 42, and a push arm mounting hole 422 extending through the push arm mounting protrusion 421 in the horizontal direction is provided.

[0090] Fig.15 It is the structural diagram of the card pushing arm in this embodiment.

[0091] like Fig.15 As shown, the card pushing arm 43 is a telescopic arm, which is generally L-shaped as a whole, and includes a card pushing head 431, a card pushing slider 432, a connecting arm portion 433, and a guide arm portion 434.

[0092] The connecting arm portion 433 is generally rectangular in shape as a whole, and has a connecting groove 4331 extending along its length direction. The cross section of the connecting groove 4331 in its extending direction is similar to the top shape of the character "concave", that is, it includes an upper horizontal section, a transition section extending obliquely downward, a lower horizontal section, a transition section extending obliquely upward, and another upper horizontal section connected in sequence, and the connection positions between the sections have rounded corners. The connecting arm portion 433 is movably inserted into the square push arm mounting hole 422. The push arm mounting hole 422 is arranged on one side of the center 42A of the push card rotating seat 42, that is, the push card arm 43 is eccentrically arranged relative to the push card rotating seat 42 (push card slave gear).

[0093] One end of the guide arm portion 434 is embedded and fixed in the connecting groove 4331, and the other end is fixedly installed with the card pushing head 431. The guide arm portion 434 is in the shape of a special-shaped strip, and its cross-sectional shape is adapted to the cross-sectional shape of the telescopic accommodating groove 4331, that is, it is also similar to the top shape of the word "concave", and the connection position between each section has a rounded corner, so that the guide arm portion 434 has sufficient structural strength while being thin, and can also play a certain guiding role when it is telescoped relative to the connecting arm portion 433. One side of the middle part of the guide arm portion 434 has an L-shaped mounting plate portion 4341 extending downward, and a card pushing slider 432 is rotatably installed below the end of the mounting plate portion 4341. The card pushing slider 432 is cylindrical, and its axial direction is perpendicular to the length direction of the card pushing arm 43. The card pushing slider 432 is slidably embedded in the rotating groove 411.

[0094] The card pushing head 431 is a special-shaped part, which is generally L-shaped as a whole, and has a card pushing head mounting portion 4311 and a card pushing rod portion 4312 that are approximately perpendicular to each other. The card pushing head mounting portion 4311 has a mounting hole in the shape of the top of the word "concave", which is embedded in the other end of the guide arm portion 433. The card pushing rod portion 4312 includes an upper card pushing portion 43121 and a lower card pushing portion 43122. The upper card pushing portion 43121 is generally in the shape of a rectangular plate, and one side of it is a first card pushing surface 43121a, which is a long strip plane and is perpendicular to the width direction of the card pushing arm 43. The lower card pushing portion 43122 is roughly L-shaped, and it first extends downward from the bottom of the upper card pushing portion 43121, and then extends outward from one side of the first card pushing surface 43121a of the upper card pushing portion 43121 along the width direction of the card pushing arm 43, forming a lateral protrusion at the bottom of the card pushing rod portion 4312, and the outer end surface of the lateral protrusion is the second card pushing surface 43122a, which is a rectangular plane and is also perpendicular to the width direction of the card pushing arm 43. That is, in the width direction of the card pushing arm 43, the second card pushing surface 43122a is located at a more outer position than the first card pushing surface 43121a. In addition, the other side of the card pushing rod portion 4312 opposite to the second card pushing surface 43122a is inclined relative to the length direction of the card pushing rod portion 4312, so that the width of the bottom end of the card pushing rod portion 4312 is small.

[0095] In this embodiment, the guide arm portion 434 is made of metal, and the connecting arm portion 433 and the card pushing head 431 are both made of plastic.

[0096] The card pushing motor 44 is arranged below the card pushing seat 41, and a card pushing main gear 45 is installed on its output shaft. The lower surface of the card pushing rotating seat 42 is provided with a rotating seat tooth 423 (i.e., a card pushing slave gear) meshing with the card pushing main gear 45, so that the card pushing motor 44 can drive the card pushing rotating seat 42 to rotate. When the card pushing rotating seat 42 rotates, the card pushing slider 432 also moves in the rotating groove 411 accordingly, driving the card pushing head 431 to push the card pile in the card groove 321. Since the rotating groove 411 has a concave section 412, when the card pushing slider 432 reaches the position of the concave section 412, the distance between the card pushing slider 432 and the rotation center (i.e., the rotation axis 310) of the card pushing rotating seat 42 will be shortened, so that the card pushing head 431 shrinks inwardly toward the rotation center direction without contacting with the components of the card supply device 10 and the card stacking device 20, thereby avoiding mutual interference.

[0097] When the card pushing head 431 is in the card slot 312, the second card pushing surface 43122a is located at the lower card slot 312B, and the upper part of the first card pushing surface 43121a is located at the upper card slot 312A, and these two card pushing surfaces are basically perpendicular to the extension direction of the card slot 312. Therefore, in the card pushing direction, the lower layer of mahjong tiles in the card slot 312 are relatively forward than the upper layer of mahjong tiles, that is, the upper layer of mahjong tiles always remain slightly behind during the movement.

[0098] When the pile of tiles reaches the tile lifting device 50, the friction between the upper tiles is small because they only touch the lower tiles. After the thrust of the tile pushing head 431 is removed, it is usually easy to slide forward a short distance. In this embodiment, the two structural designs of the tile pushing protrusion 433 and the larger movement radius of the tile loading slot 312A are coordinated to keep the upper tiles slightly behind during the movement. After the thrust is removed, the upper tiles slide this short distance and overlap just above the lower tiles, so that the tiles can be stacked neatly when loading.

[0099] Fig.16 1 is a top view of the card storage device and the card pushing device in this embodiment, and the card pushing rotating seat is not shown in the figure. Fig.17 yes Fig.16 An enlarged view of the inner part of the middle frame A. Fig.16 and Fig.17 The push card rotating seat is not shown, and Fig.17 The edge structure of the card-pushing gear is shown in dotted lines.

[0100] like Fig.16 and Fig.17 As shown, the card pushing sensing component 46 includes a first card pushing sensor 461 , a second card pushing sensor 462 , a card pushing sensing portion (not shown in the figure), a card pushing sensing circuit board 464 , and a card storage sensor 465 .

[0101] Among them, a side edge of the push card rotating seat 42 has a sensing part mounting hole 425, and the sensing part mounting hole 425 is axially connected to the push card rotating seat 42, and its axial cross section is circular, and the aperture inside is larger than the aperture at both ends. The push card sensing part is a roughly cylindrical magnet, which is arranged in the sensing part mounting hole 425, so it can move along an arc as the push card rotating seat 42 rotates. In addition, the sensing part mounting hole 425 and the push arm mounting hole 422 are respectively located on both sides of a diameter direction of the push card rotating seat 42, and an angle is formed between the connecting direction of the sensing part mounting hole 425 and the center 42A of the push card rotating seat 42 and the length direction of the push card arm 42, and the angle is an acute angle, and the angle is 40° to 50°, and 45° in the present embodiment.

[0102] The card pushing sensing circuit board 464 is roughly T-shaped, and the upper side of the T is arc-shaped. The first card pushing sensor 461 and the second card pushing sensor 462 are both magnetic induction sensors, which are respectively arranged on the two ends of the upper side of the card pushing sensing circuit board 464, and the two sensors and the card pushing sensing part are all located on the same circumference of the card pushing rotating seat 42, that is, the distances of the three to the central axis of the card pushing rotating seat 42 are basically equal, so the two sensors are located directly below the moving path of the card pushing sensing part. When the card pushing sensing part moves to the top of one of the two sensors, the sensor can sense the card pushing sensing part and generate a corresponding sensing signal, wherein the first card pushing sensor 461 generates a first card pushing position sensing signal when sensing the card pushing sensing part, and the second card pushing sensor 462 generates a second card pushing position sensing signal when sensing the card pushing sensing part.

[0103] Wherein, the first card pushing sensor 461 is relatively closer to the card inlet 312C, and is correspondingly arranged with the predetermined stacking card entrance waiting position P1 in front of the card inlet 312C. When the card pushing rotating seat 42 rotates to the time when the first card pushing sensor 461 senses the card pushing sensing part (that is, the card pushing sensing part is roughly located directly above the first card pushing sensor 461), and under the guidance of the recessed section 412, the card pushing head 431 is located at the predetermined stacking card entrance waiting position P1. In the present embodiment, the stacking card entrance waiting position P1 is a position behind the card inlet 312C along the card pushing direction, located between the card inlet 312C and the card lifting device 50, and there is relatively large free space at this position. The above-mentioned recessed section 412 is located next to the stacking card entrance waiting position P1.

[0104] The second card pushing sensor 462 is relatively closer to the card outlet 312D and is arranged corresponding to the predetermined card raising entrance waiting position P2 in front of the card outlet 312D. When the card pushing rotating seat 42 rotates to the point where the second card pushing sensor 462 senses the card pushing sensing part, the card pushing head 431 is located at the card raising entrance waiting position P2.

[0105] like Fig.16 As shown, the line connecting the first card pushing sensor 461 and the center 42A of the card pushing rotating seat 42 is the first line L1, the line connecting the second card pushing sensor 462 and the center 42A of the card pushing rotating seat 42 is the second line L2, and the angle between the first line L1 and the second line L2 is 40° to 50°, and is 45° in this embodiment. And the angle is set correspondingly to the angle between the direction of the line connecting the above-mentioned sensor mounting hole 425 and the center 42A of the card pushing rotating seat 42 and the length direction of the card pushing arm 42.

[0106] In the initial state, the card pushing head 431 is located at the card stacking entrance waiting position P1, thereby avoiding interference with the card stacking device 20. After the card stacking device 20 completes the stacking and pushing of a predetermined number of mahjong tiles to form several piles of mahjong tiles, the card pushing motor 44 drives the card pushing arm 43 to rotate, and the card pushing arm 43 pushes these several piles of mahjong tiles to move along the card slot 312 until the card pushing arm 43 rotates to the point where the first card pushing sensor 461 senses the card pushing sensing part, and the card pushing motor 44 is controlled to stop according to the sensing signal, so that the card pushing head 431 stops at the card raising entrance waiting position P2. At this time, the several piles of mahjong tiles pushed by it are located at the bottom of the carrying plate 52. The card pushing head 431 can prevent these several piles of mahjong tiles from falling from the carrying plate 52, and will not interfere with the plate end of the carrying plate 52.

[0107] Then, when the supporting plate 52 rotates to raise the cards, the card pushing motor 44 drives the card pushing arm 43 to rotate again until the card pushing arm 43 rotates to the point where the second card pushing sensor 462 senses the card pushing sensing part, and controls the card pushing motor 44 to stop according to the sensing signal, so that the card pushing head 431 stops at the card stacking entrance waiting position P1. At this time, the card pushing head 431 is located near the card inlet 312C and will not interfere with the card stacking device 20.

[0108] The card storage sensor 465 is arranged at the card outlet 312D of the card slot 312 (i.e., it is close to the end of the card lifting device 50). It is a magnetic induction sensor. When there is a pile of cards at the card outlet 312D, the magnet in the mahjong tiles 200 is sensed and a corresponding sensing signal is generated. Among them, when the first pile of cards in the card slot 312 arrives at the card outlet 312D, the card storage sensor 465 senses the first magnet (i.e., before sensing the magnet, there is a long time without sensing the magnet, and the duration exceeds the predetermined duration threshold), and generates a card suspension sensing signal; subsequently, when multiple piles of cards in the card slot 312 are pushed and pass through the card outlet 312D in sequence, the card storage sensor 465 senses a plurality of continuous magnets (i.e., the interval between two adjacent magnets is sensed to be short, and the duration is less than the predetermined duration threshold), and generates a card loading sensing signal.

[0109] Fig.18 : is a structural diagram of the card-raising device in this embodiment, Fig.19 : is a structural diagram of part of the structure of the card-raising device in this embodiment, Fig.19 The carrier frame is omitted.

[0110] like Figure 3 , Figure 4 , Fig.18 and Fig.19As shown, the card lifting device 50 is used to lift the pile of cards pushed by the card pushing device 40 to the table top, and includes a bearing unit and a swing unit, wherein the bearing unit includes a bearing frame 51 and a bearing plate 52, and the swing unit includes a swing motor 53, a swing arm 54, a swing connecting rod 55 and a swing gear set composed of a driving wheel 56 and a driven wheel 57.

[0111] The carrier frame 51 is fixedly mounted on the lower frame 106, and is located near the card supply frame 12 and is fixedly connected to the card supply frame 12 to form a frame body. An opening is formed at the lower end of one side of the carrier frame 51 to facilitate the exposure of the card suction wheel 11, and a bearing groove 511 is formed at the upper end. The bearing groove 511 has an open end 511A, and its opening faces the rear end of the card slot 312, and the depth of the bearing groove 511 gradually increases from the other end to the open end 511A.

[0112] The carrying plate 52 is used to carry the pile of cards to be loaded. The carrying plate 52 is a long strip-shaped plate-like member, one end of which is a receiving end that can receive the pile of cards pushed by the pushing arm 43 from the card slot 312, and is located at the open end 511A; the other end is a mounting end, which is rotatably mounted on the other end of the carrying slot 511 relative to the open end 511A through a rotating shaft, so that the carrying plate 52 can swing up and down in the carrying slot 511, and accordingly, its receiving end can rise or fall at the open end 511A.

[0113] The table top 105 is provided with a card output slot 105A corresponding to the position and matching the shape of the supporting plate 52. When the supporting plate 52 swings upward until the receiving end rises to the highest position, the supporting plate 52 as a whole is exposed from the table top at the card output slot 105, and the user can take away the card pile on the supporting plate 52. The position of the supporting plate 52 in this state is referred to as the upper swing position of the supporting plate 52 hereinafter; when the supporting plate 52 swings downward until the receiving end drops to the lowest position, the receiving end is basically flush with the bottom of the card slot 312, and the card pushing arm 43 can push the card pile in the card slot 312 from the receiving end to the supporting plate 52. The position of the supporting plate 52 in this state is referred to as the lower swing position of the supporting plate 52 hereinafter.

[0114] The swing motor 53 is installed below the card storage tray 31 , and its output shaft extends upward to above the card storage tray 31 .

[0115] The driving wheel 56 is mounted on the output shaft of the swing motor 53 and can rotate under the drive of the swing motor 53 .

[0116] A driven wheel groove 314 is provided on the card storage tray 31 near the driving wheel 56. The driven wheel 57 is rotatably installed in the driven wheel groove 314 through a driven wheel shaft 316. It is meshed with the driving wheel 56 and can be driven by the driving wheel 56 to rotate under the drive of the swing motor 53.

[0117] Fig. 20 It is a structural diagram of the surface of one side of the driven wheel in this embodiment.

[0118] like Fig. 20 As shown, a track groove 572 is provided on one side surface of the driven wheel 57. The track groove 572 is in a shape of a protrusion on one side, and the farthest end 572A is farthest from the center of the driven wheel 57 (the rotation center, that is, the center of the driven wheel shaft 316), and the closest end 572B is farthest from the center of the driven wheel 57.

[0119] Fig.21 2 is a structural diagram of the swing connecting rod in this embodiment.

[0120] like Fig.21 As shown, both ends of the swing link 55 each have an end in the shape of a straight rod, one of which is a driven wheel mating end 551 mating with the driven wheel 57, and the other is a swing mating end 552 mating with the swing arm 54. In this embodiment, the length directions of the driven wheel mating end 551 and the swing mating end 552 are parallel to each other. The middle part of the swing link 55 is a first transition section 555 and a second transition section 556 connecting the driven wheel mating end 551 and the swing mating end 552. One end of the first transition section 555 is connected to the driven wheel mating end 551 and is inclined relative to it, and the angle between the two is an obtuse angle. The two ends of the second transition section 556 are respectively connected to the other end of the first transition section 555 and the swing mating end 552, and are approximately perpendicular to the first transition section 555, and are inclined relative to the swing mating end 552, and the angle between the two is an obtuse angle. A yield groove 5551 is provided at one end of the first transition section 555 close to the second transition section 556. The yield groove 5551 runs through the first transition section 555 in the width direction. The groove width is slightly larger than the width of the bottom end of the card pushing rod portion 4212 of the card pushing arm 42. Therefore, when the card pushing arm 42 rotates, the yield groove 5551 can make way for it.

[0121] A straight connecting rod matching groove 315 having a size matching that of the driven wheel matching end 551 is provided in the driven wheel groove 314 . The driven wheel matching end 551 is located in the connecting rod matching groove 315 , so that the driven wheel matching end 551 is approximately located below the driven wheel 57 .

[0122] The surface of the side where the track groove 572 of the driven wheel 57 is located faces downward, and a roller 553 is also provided on the upper surface of the driven wheel mating end 551. The roller 553 is slidably embedded in the track groove 572, so that when the driven wheel 57 rotates, the roller 553 can drive the swing link 55 to reciprocate along the length direction of the link mating groove 315.

[0123] A swing shaft 541 is disposed at the lower end of the swing arm 54 . The swing shaft 541 is disposed through the support frame 51 , so that the swing arm 54 can rotate around the swing shaft 541 and swing up and down.

[0124] The end of the swing shaft portion 541 exposed on the outside of the carrier frame 51 is provided with swing shaft teeth 542 distributed along the circumferential direction, and the swing matching end 552 is provided with swing matching teeth 554 distributed along the length direction. The swing shaft teeth 542 and the swing matching teeth 554 are meshed with each other. When the swing link 55 reciprocates and translates, it can drive the swing arm 54 to swing up and down.

[0125] A bearing matching groove 521 is provided on the lower surface of the receiving end of the bearing plate 52, and a swinging slider 543 is provided on the upper end of the swinging arm 54 to be slidably matched in the bearing matching groove 521. When the swinging arm 54 swings up and down driven by the swinging link 55, the receiving end of the bearing plate 52 can be driven to swing up and down, that is, to swing back and forth between the upper swinging position and the lower swinging position.

[0126] Since the distal end 572A and the proximal end 572B of the track groove 572 correspond to the two ends of the reciprocating translation stroke of the swing link 55 respectively, when the roller 553 moves toward the distal end 572A, the swing arm 54 will rotate in the direction away from the swing link 55, and vice versa.

[0127] In the present invention, the relative positions of the swing link 55 and the swing arm 54 can be changed according to the different meshing states of the swing shaft teeth 542 and the swing matching teeth 554, so the movement of the swing link 55 can correspond to the different lifting and lowering movements of the swing arm 54, as follows:

[0128] When the swing link 55 is in a retracted state (i.e., the roller 553 is located at the proximal end 572B and the swing link 55 is located closer to the driven wheel 57), and the swing arm 54 is facing upward, the rotational movement of the swing arm 54 away from the swing link 55 will cause its upper end to move downward; when the swing link 55 is in a retracted state and the swing arm 54 is facing the swing link 55 (at this time the swing arm 54 is in an approximately horizontal state), the rotational movement of the swing arm 54 away from the swing link 55 will cause its upper end to move upward.

[0129] Therefore, the distal end 572A of the track groove 572 corresponds to one of the upper swing position and the lower swing position of the supporting plate 52, while the proximal end 572B corresponds to the other one of the upper swing position and the lower swing position.

[0130] In this embodiment, the former situation (i.e. the situation where the swing link 55 is in a retracted state and the swing arm 54 is in a vertical state) is taken as an example for specific description.

[0131] Fig. 22 It is a structural diagram of the other side surface of the driven wheel in this embodiment.

[0132] like Fig. 22As shown, the other side surface (i.e., the upward surface) of the driven wheel 57 is provided with a first card-raising induction portion 58 and a second card-raising induction portion 59, both of which are magnets. With the center of the driven wheel shaft 316 as the center of the circle, the first card-raising induction portion 58 and the second card-raising induction portion 59 are distributed on both sides of the driven wheel shaft 316, and the two are located on the same diameter of the driven wheel 57, but on different circumferences of the driven wheel 57. In addition, the distal end 572A and the proximal end 572B of this embodiment are also on the same diameter line of the driven wheel 57.

[0133] The swing unit also includes a sensing component installed above the driven wheel 57, which includes a first swing sensor 61 matched with the first card-raising sensing part 58 and a second swing sensor 62 matched with the second sensing part 58, both of which are magnetic induction sensors.

[0134] In this embodiment, the first swing sensor 61 and the second swing sensor 62 are both set at specific positions, so that when the roller 553 reaches the proximal end 572B, the first card lifting sensor 58 just reaches under the first swing sensor 61, and when the roller 553 reaches the distal end 572A, the second card lifting sensor 59 just reaches under the second swing sensor 62.

[0135] Thus, when the roller 553 reaches the proximal end 572B, so that the swing arm 54 is in a vertical state and the supporting plate 52 is in an upper swing position, the first swing sensor 61 just senses the first card lifting sensing part 58 and outputs a card lifting completion sensing signal; when the roller 553 reaches the distal end 572A, so that the swing arm 54 swings from a vertical state to a horizontal state and the supporting plate 52 is in a lower swing position, the second swing sensor 62 just senses the second card lifting sensing part 59 and outputs a card lifting sensing signal.

[0136] In addition, when the roller 553 is neither at the proximal end 572B nor at the distal end 572A, the first swing sensor 61 and the second swing sensor 62 do not output a sensing signal, indicating that the supporting plate 52 is at a position between the upper swing position and the lower swing position.

[0137] Therefore, the first card-raising sensor 58 of the present embodiment corresponds to the upper swing position of the carrier plate 52, and the second card-raising sensor 59 corresponds to the lower swing position of the carrier plate 52. Through the sensing signals output in real time by the first swing sensor 61 and the second swing sensor 62, it can be accurately determined whether the current carrier plate 52 is in the lower swing position, the upper swing position, or between the two positions.

[0138] Fig.23 It is a structural block diagram of the card stacking device in this embodiment.

[0139] like Figure 6 and Fig.23As shown, the stacking device 20 also includes a stacking card counting sensor 29, which is arranged near the stacking block 21. Specifically, it can be installed on the card slot related parts of the card storage device 30, or it can be installed by a separate mounting bracket. The stacking card counting sensor 29 is a magnetic induction sensor, which can generate an induction signal when the mahjong tiles with magnets embedded in it pass through, so as to count the mahjong tiles stacked and entering the card slot 312. Since two mahjong tiles 200 are stacked to form a pile, the total number of mahjong tiles 200 counted according to the induction signal of the stacking card counting sensor 29 is divided by 2, and the number of piles of mahjong tiles 200 can be known at the same time.

[0140] The card stacking device 20 also includes a card stacking control unit 291, which is respectively connected to the card stacking counting sensor 29 and the card stacking motor 24, and sends a corresponding card stacking control signal to the card stacking motor 24 according to the induction counting result of the card stacking counting sensor 29. The card stacking motor 24 receives the card stacking control signal, operates according to the signal and drives the card stacking driving wheel 23 to rotate, so that the card stacking block driving rod 22 swings up and down, drives the card stacking block 21 to move up and down through its movable end, and makes the card shifting driving block 27 intermittently drive the card shifting block 25 to move forward and backward, thereby realizing card stacking and card shifting, forming multiple card piles.

[0141] In this embodiment, in the first card loading mode, the control device 108 generates a stacking completion sensing signal when the count of the stacking counting sensor 29 reaches k piles. In the second card loading mode, the control device 108 generates a first stacking completion sensing signal when the count of the stacking counting sensor 29 reaches m piles, and generates a second stacking completion sensing signal when the count reaches n piles.

[0142] Fig.24 It is a structural block diagram of the card pushing control unit in this embodiment.

[0143] like Fig.24 As shown, the card pushing device 40 also includes a card pushing control unit 47, which is respectively connected to the card pushing motor 44, the first card pushing sensor 461, the second card pushing sensor 462, and the card storage sensor 465, and controls the card pushing motor 44 under the control of the control device 108 according to the sensing results of the first card pushing sensor 461 and the second card pushing sensor 462 on the card pushing sensing part, and the sensing results of the card storage sensor 465 on the mahjong cards at the card outlet 312D of the card slot 312.

[0144] Specifically, the card pushing control unit 47 receives the above-mentioned card stacking completion signal, or the first batch of card stacking completion signal and the second batch of card stacking completion signal according to the currently set game mode. In both game modes, the card pushing control unit 47 receives the above-mentioned card stop sensing signal, the first card pushing position sensing signal, the second card pushing position sensing signal, the card raising sensing signal, and the card raising completion sensing signal, and controls the card pushing motor 44 according to the received signals.

[0145] Wherein, in the first card-loading mode, each card-loading mechanism 101 puts 18 piles of cards on the desktop at one time.Receive the stacking completion signal in the first card-loading mode, representing that the stacking device 20 has stacked 18 piles of cards and placed in the card slot 312, wherein the last pile of cards is located at the card inlet 312C. The card pushing control unit 47 controls the card pushing motor 44 to start when receiving the stacking completion signal in the first card-loading mode, so that the card pushing motor 44 drives the card pushing rotating seat 42 and the card pushing arm 43 to rotate, and drives the card pushing head 431 to move in the card slot 312 and push the stacked 18 piles of cards to move toward the card outlet 312D. In the card pushing process, as mentioned above, the motion path of the upper card is larger, and the first card pushing face for promoting the upper card is more backward in the card pushing direction, so the upper card can always remain slightly behind the state of the lower card.

[0146] In the second card-loading mode, each card-loading mechanism 101 firstly puts the first batch of m piles of cards as the starting hand of each user on the desktop, and then puts the second batch of n piles of cards on the desktop for the user to touch cards for the second time. Under the second card-loading mode, the first stack of cards is received to complete the signal, which represents that the stacking device 20 has stacked the first batch of m piles of cards and placed them in the card slot 312, and the last pile of cards therein is located at the card inlet 312C. The card-pushing control unit 47 controls the card-pushing motor 44 to start when receiving the first stack of cards completion signal under the second card-loading mode, so that the card-pushing head 431 promotes the first batch of m piles of cards. Under the second card-loading mode, the second stack of cards is received to complete the signal, which represents that the stacking device 20 has stacked the second batch of n piles of cards and placed them in the card slot 312, and the last pile of cards therein is located at the card inlet 312C. The card-pushing control unit 47 controls the card-pushing motor 44 to start when receiving the second stack of cards completion signal under the second card-loading mode, so that the card-pushing head 431 promotes the second batch of n piles of cards.

[0147] In both game modes, receiving the card stop sensing signal means that in the card pushing process, the first pile of cards among the piles of cards has been pushed to the card outlet 312D. When receiving the card stop sensing signal, the card pushing control unit 47 controls the card pushing motor 44 to stop, so that the first pile of cards among the piles of cards stops at the card outlet 312D to wait for the card lifting device 50, thereby avoiding pushing the cards out of the card slot 312.

[0148] In both game modes, receiving the second card pushing position sensing signal represents that the card pushing head 431 has arrived at the waiting position P2 of the card raising entrance, that is, in the card pushing process, the last pile of cards in the pile of cards has also been pushed onto the bearing plate 52, that is, these piles of cards have been completely pushed onto the bearing plate 52 and the desktop (the bearing plate 52 can carry 6 to 8 piles of cards. When pushing 12 or 18 piles of cards, the first piles of cards will be directly pushed onto the desktop). The card pushing control unit 47 controls the card pushing motor 44 to stop when receiving the second card pushing position sensing signal, so that the card pushing head 431 stops at the P2 position to avoid interference between the card pushing head 431 and the rotation of the bearing plate 52, and to limit the pile of cards pushed onto the bearing plate 52 to avoid sliding off the bearing plate 52 and causing the wrong number of cards to be raised.

[0149] In both game modes, receiving the first card pushing position sensing signal indicates that the card pushing head 431 has reached the card stacking entrance waiting position P1, that is, after a card pushing is completed, the card pushing head 431 has been reset. The card pushing control unit 47 controls the card pushing motor 44 to stop when receiving the first card pushing position sensing signal, so that the card pushing head 431 stops at the P1 position to avoid interference between the card pushing head 431 and the card stacking and card dialing action of the card stacking device 20, and the P1 position is very close to the card inlet 312C. When the card stacking is completed and the card pushing needs to be started, the card pushing head 431 can quickly move to the card inlet 312C to start the card pushing action.

[0150] In both game modes, receiving the card-raising sensing signal indicates that the receiving end of the carrier plate 52 has been lowered to the right position and can receive the card pile. When receiving the card-raising sensing signal, the card-pushing control unit 47 controls the card-pushing motor 44 to start, so that the card-pushing head 431 further pushes the card pile pushed to the card outlet 312D onto the carrier plate 52.

[0151] In both game modes, receiving the card raising completion sensing signal indicates that the receiving end of the carrier plate 52 has risen to the right position, that is, all the mahjong tiles have been raised to the table, and the carrier plate 52 will not interfere with the rotation of the card pushing arm 43. When receiving the card raising completion sensing signal, the card pushing control unit 47 controls the card pushing motor 44 to start, so that the card pushing head 431 moves from the P2 position to the P1 position, so that the card pushing arm 43 is reset.

[0152] In this embodiment, when the user needs to shuffle the mahjong tiles 200, the user can input a shuffling instruction and a play mode setting instruction through the operating panel 1021, and the control device 108 controls the operating panel mechanism 102 to descend and controls the shuffling mechanism 107 to start shuffling; at this time, the user can push the scattered mahjong tiles on the table board 105 into the gap to shuffle the tiles.

[0153] After the shuffling is completed (for example, a certain shuffling time can be set), the control device 108 can control the card supply device 10 to supply cards and control the stacking device 20 to stack cards according to the play mode set by the user. At the same time, the card pushing control unit 47 controls the card pushing head 431 to reach the card stacking entrance waiting position.

[0154] During the stacking process, the card supply device 108 can determine how many piles of cards have entered the card slot 312 according to the sensing signal of the stacking card counting sensor 29. Once the required number of piles (for example, the number of piles required according to the current game mode) is reached, the card supply device 108 controls the stacking device 20 to pause or stop stacking cards, and controls the card pushing device 40 to push cards. Subsequently, if the card storage sensor 465 senses the mahjong tiles for the first time, it means that the card pushing device 40 has pushed the piles of cards into place, and the first pile of cards has reached the end of the card slot 312. The control device 108 can directly control the card raising device 50 to raise the cards at this time, or wait for a while, and control the card raising device 50 to raise the cards according to the card raising instruction input by the user from the operating panel 1021 when the user wants to raise the cards.

[0155] In the above process, after a specified number of card piles are stacked, the card pushing operation can begin. The following will explain the card pushing action and corresponding control in the two game modes respectively.

[0156] Fig.25 This is a flow chart of the card pushing device in the first card loading mode in this embodiment.

[0157] The first card-loading mode is to put k piles of cards (for example, 18 piles of cards) on the table at one time. Fig.25 As shown, in the first card loading mode, the process of the card pushing device 40 cooperating with other devices to complete the card pushing operation includes the following steps:

[0158] Step S1-1, the card pushing control unit 47 receives a card stacking completion signal.

[0159] Step S1-2, the card pushing control unit 47 determines whether 18 piles of cards have been stacked according to the card stacking completion signal (i.e., whether the signal is received). When it is determined that they have been stacked, the card pushing motor 44 is controlled to start, and the card pushing motor 44 drives the card pushing rotating seat 42 and the card pushing arm 43 to rotate synchronously, and the card pushing head 431 pushes the card pile in the card slot 312 toward the card outlet 312D.

[0160] Step S1-3, the card pushing control unit 47 receives the card stopping sensing signal.

[0161] Step S1-4, the card pushing control unit 47 determines whether the first pile of cards in the 18 piles has been pushed to the card outlet 312D according to the card stopping sensing signal. When it is judged to be yes, it controls the card pushing motor 44 to stop, so that the first pile of cards stops at the card outlet 312D to wait for the cooperation of the card raising device 50.

[0162] Step S1-5, the card pushing control unit 47 receives the card raising sensing signal.

[0163] Step S1-6, the card pushing control unit 47 determines whether the receiving end of the supporting plate 52 has been lowered into place according to the card lifting sensing signal, that is, whether the supporting plate 52 can receive the card pile. When it is judged to be yes, the card pushing motor 44 is controlled to start, and the card pushing motor 44 drives the card pushing rotating seat 42 and the card pushing arm 43 to rotate synchronously, and the card pushing head 431 pushes the card pile in the card slot 312 further toward the supporting plate 52.

[0164] Step S1-7, the card pushing control unit 47 receives the second card pushing position sensing signal.

[0165] Step S1-8, the card pushing control unit 47 determines whether the last pile of cards in the 18 piles has been pushed onto the supporting plate 52 according to the second card pushing position sensing signal, that is, whether the k pile of cards have been pushed onto the supporting plate 52 and the table top. When it is judged to be yes, the card pushing motor 44 is controlled to stop, so that the card pushing head 431 stops at the card lifting entrance waiting position P2 to prevent interference with the supporting plate 52, and to limit the pile of cards pushed onto the supporting plate 52.

[0166] Step S1-9, the card pushing control unit 47 receives the card raising completion sensing signal.

[0167] Step S1-10, the card pushing control unit 47 determines whether the receiving end of the supporting plate 52 has risen to the right position according to the card raising completion sensing signal, that is, the card raising action has been completed. When it is judged to be yes, the card pushing motor 44 is controlled to start, so that the card pushing head 431 is reset.

[0168] Step S1-11, the card pushing control unit 47 receives a first card pushing position sensing signal.

[0169] Step S1-12, the card pushing control unit 47 determines whether the card pushing head 431 has moved to the stacking disk entrance waiting position P1 according to the first card pushing position sensing signal, that is, whether the card pushing arm 43 has been reset. When it is judged to be yes, the card pushing motor 44 is controlled to stop, so that the card pushing head 431 stops at the stacking disk entrance waiting position P1.

[0170] Through the above steps, a complete card pushing and resetting action in the first card loading mode is completed.

[0171] Fig.261 is a flow chart of the card pushing device in the second card loading mode in this embodiment. The left side of the figure is the process of pushing a batch of m piles of cards, and the right side of the figure is the process of pushing the second batch of n piles of cards. Since the corresponding control and device actions in each batch are basically the same as the above process, Fig.26 In a simplified manner.

[0172] The second card-loading mode is that the first batch of m piles of cards (for example, 6 piles of cards) are first loaded as the user's starting hand, and the second batch of n piles of cards (for example, 12 piles of cards) are loaded for the user to draw cards. Fig.26 As shown, in the second card loading mode, the process of the card pushing device 40 cooperating with other devices to complete the card pushing operation includes the following steps:

[0173] Step S2-1, the card pushing control unit 47 receives a first card stacking completion signal.

[0174] Step S2-2, the card pushing control unit 47 determines whether the first batch of 6 piles of cards have been stacked according to the first card stacking completion signal, and controls the card pushing motor 44 to start when it is determined to be yes, so that the card pushing head 431 pushes the first batch of 6 piles of cards toward the card outlet 312D.

[0175] Step S2-3, the card pushing control unit 47 receives the card stopping sensing signal.

[0176] Step S2-4, the card pushing control unit 47 determines whether the first pile of cards in the first batch of 6 piles of cards has reached the card outlet 312D according to the card stopping sensing signal, and controls the card pushing motor 44 to stop when it is determined to be yes.

[0177] Step S2-5, the card pushing control unit 47 receives the card raising sensing signal.

[0178] Step S2-6, the card pushing control unit 47 determines whether the receiving end of the supporting plate 52 has been lowered into place according to the card lifting sensing signal, and controls the card pushing motor 44 to start when it is determined to be yes, and pushes the first batch of 6 piles of cards onto the supporting plate 52.

[0179] Step S2-7, the card pushing control unit 47 receives the second card pushing position sensing signal.

[0180] Step S2-8, the card pushing control unit 47 determines whether the last pile of cards in the first batch of 6 piles has been pushed onto the supporting plate 52 according to the second card pushing position sensing signal, and controls the card pushing motor 44 to stop when it is determined to be yes.

[0181] Step S2-9, the card pushing control unit 47 receives the card raising completion sensing signal.

[0182] Step S2-10, the card pushing control unit 47 determines whether the receiving end of the carrier plate 52 has risen to the right position according to the card lifting completion sensing signal, and controls the card pushing motor 44 to start when it is determined to be yes, so that the card pushing head 431 is reset.

[0183] Step S2-11, the card pushing control unit 47 receives a first card pushing position sensing signal.

[0184] In step S2-12, the card pushing control unit 47 determines whether the card pushing head 431 has moved to the card stacking entrance waiting position P1 according to the first card pushing position sensing signal, and controls the card pushing motor 44 to stop when the determination is yes.

[0185] Step S2-13: the card pushing control unit 47 receives a second card stacking completion signal.

[0186] In step S2-14, the card pushing control unit 47 determines whether the second batch of 12 piles of cards have been stacked according to the second card stacking completion signal. If it is determined to be yes, the card pushing motor 44 is controlled to start, so that the card pushing head 431 pushes the second batch of 12 piles of cards toward the card outlet 312D.

[0187] In actual use, the mahjong machine usually uses two sets of mahjong tiles, and the user uses one set of mahjong tiles to play on the desktop, and the other set of mahjong tiles is stacked and pushed inside the mahjong machine. Generally speaking, the time for the user to use one set of mahjong tiles to play the last game will be longer, which is obviously longer than the total time of stacking two batches of card piles. Therefore, in an alternative solution, the above steps S2-11 to S-14 may not be performed, that is, the first push card position sensing signal and the second stack card completion signal are not received, but after the push card head 431 is reset, the push card motor 44 is allowed to continue to run, and the second batch of n pile cards are directly pushed to the card outlet 312D to wait for the card to be raised. This can make the control process relatively simpler.

[0188] Step S2-15, the card pushing control unit 47 receives the card stopping sensing signal.

[0189] Step S2-16, the card pushing control unit 47 determines whether the first pile of cards in the second batch of 12 piles of cards has reached the card outlet 312D according to the card stop sensing signal, and controls the card pushing motor 44 to stop when it is determined to be yes.

[0190] Step S2-17, the card pushing control unit 47 receives the card raising sensing signal.

[0191] Step S2-18, the card pushing control unit 47 determines whether the receiving end of the supporting plate 52 has been lowered into place according to the card lifting sensing signal, and controls the card pushing motor 44 to start when it is determined to be yes, and pushes the second batch of 12 piles of cards onto the supporting plate 52 and the table.

[0192] Step S2-19, the card pushing control unit 47 receives the second card pushing position sensing signal.

[0193] Step S2-20, the card pushing control unit 47 determines whether the last pile of cards in the second batch of 12 piles of cards has been pushed onto the supporting plate 52 according to the second card pushing position sensing signal, and controls the card pushing motor 44 to stop when it is determined to be yes.

[0194] Step S2-21, the card pushing control unit 47 receives the card raising completion sensing signal.

[0195] Step S2-22, the card pushing control unit 47 determines whether the receiving end of the carrier plate 52 has risen to the right position according to the card lifting completion sensing signal, and controls the card pushing motor 44 to start when it is determined to be yes, so that the card pushing head 431 is reset.

[0196] Step S2-23, the card pushing control unit 47 receives the first card pushing position sensing signal.

[0197] In step S2-24, the card pushing control unit 47 determines whether the card pushing head 431 has moved to the stacking tray entrance waiting position P1 according to the first card pushing position sensing signal, and controls the card pushing motor 44 to stop when the determination is yes.

[0198] Through the above steps, the card pushing actions of two batches of cards with different numbers of tricks can be completed in sequence.

[0199] Fig. 27 It is a structural block diagram of the card-raising device in this embodiment.

[0200] like Fig. 27 As shown, the card-raising device 50 also includes a card-raising control unit 501, which is respectively connected to the swing motor 53, the load-bearing sensor, the first swing sensor 61, and the second swing sensor 62. The swing motor 53 receives the card-raising control signal sent by the card-raising control unit 501, and operates and drives the swing driving wheel 56 to rotate according to the card-raising control signal, thereby realizing the actions of waiting, card-raising and resetting the load-bearing plate 52.

[0201] Functions and Effects of the Embodiments

[0202] According to the card pushing device, card loading mechanism and mahjong machine provided by the present embodiment, since the card pushing device includes a card pushing rotating seat, a card pushing arm and a card pushing sensing assembly, the card pushing sensing assembly includes a card pushing sensing part arranged on the card pushing rotating seat and a first card pushing sensor and a second card pushing sensor correspondingly arranged below the card pushing rotating seat, and the two sensors are respectively arranged corresponding to a predetermined card stacking entrance waiting position in front of a card inlet of the card slot and a predetermined card raising entrance sensing position in front of a card outlet. Therefore, through the sensing signals of the two sensors, the current position state of the card pushing head of the card pushing arm can be accurately judged, and then the card pushing motor can be controlled according to the sensing signal, so that the card pushing head can wait outside the card inlet when the card stacking device is stacking cards, and will not interfere with it; and the card pushing head can wait at the card outlet after pushing multiple piles of cards onto the card raising device, and will not interfere with the card raising device, and it can also prevent the piles of cards on the card raising device from sliding down and causing a shortage of mahjong tiles on the desktop.

[0203] In the embodiment, the card pushing sensing component also includes a card storage sensor. The card pushing control unit controls the card pushing motor to stop when the card storage sensor senses a pile of cards for the first time during the card pushing process, thereby enabling several piles of cards to stop in front of the card outlet, with the first pile of cards being located at the card outlet, waiting for the card lifting device to complete its action, without mistakenly pushing the pile of cards down the card slot, which would result in an incorrect number of cards during subsequent play.

[0204] Furthermore, the card pushing control unit also receives a card lifting sensing signal from the card lifting device, and controls the card pushing motor to start when receiving the signal, so that it can start pushing the card pile onto the carrying plate when it detects that the receiving end of the carrying plate has dropped into place, ensuring that the card pile is pushed onto the carrying plate without falling, and the card pushing can start as soon as the carrying plate is in place, which is more compact in timing. Subsequently, when the second card pushing position sensing signal is received, the card pushing motor is controlled to stop, ensuring that a specified number of card piles are pushed onto the carrying plate, and limiting it, so that the card pile will not slide off the carrying plate, and the subsequent swinging action of the card pushing head and the receiving end of the carrying plate will not interfere.

[0205] Furthermore, the card pushing control unit also receives a card raising completion sensing signal from the card raising device, and controls the motor to start when receiving the signal, so that the card pushing arm can start the resetting action when it detects that the receiving end of the supporting plate has risen into place, so that the card pushing arm and the supporting plate will not interfere with each other.

[0206] Furthermore, when the user sets the first card loading mode, the card pushing control unit controls the card pushing motor to start upon receiving a card stacking completion signal from the card stacking device, thereby starting the card pushing action after a corresponding number of card piles are stacked, without interfering with the action of the card stacking device, and a specified number of mahjong tiles can be pushed onto the table.

[0207] When the user sets the second game play mode, the card pushing control unit controls the card pushing motor to start upon receiving the first card stacking completion signal from the card stacking device, and controls the card pushing motor to start again after the card pushing arm is reset and the user operates to put cards again and then receives the second card stacking completion signal. In this way, two batches of different numbers of card piles can be pushed onto the table in sequence in two times, and the number of card piles in each batch is guaranteed to be accurate, thereby realizing this specific game play mode.

[0208] Moreover, since the card pushing sensing part is a magnet, the first card pushing sensor and the second card pushing sensor are corresponding magnetic induction sensors, and the card pushing sensing part is arranged in the through hole at the edge of the card pushing rotating seat, therefore only when the card pushing sensing part is rotated to approximately directly below the first card pushing sensor and the second card pushing sensor, one of the two sensors can sense the card pushing sensing part through the lower opening of the through hole, thereby being able to accurately locate the position of the card pushing arm, therefore, the card pushing motor is controlled based on the induction signals of the two card pushing sensors, and the card pushing head at the end of the card pushing arm can be accurately stopped at the corresponding predetermined position.

[0209] Furthermore, since there is an angle of 40° to 50° between the line connecting the two predetermined positions and the center of the card pushing rotating seat, the two card pushing sensors are respectively arranged on the two lines and corresponding to the edges of the card pushing rotating seat. Therefore, there can be sufficient spacing between the two card pushing sensors in a limited space, and the two card pushing sensors will not interfere with each other and cause false triggering, which can make the positioning control of the card pushing head more accurate.

[0210] Furthermore, since the predetermined card stacking entrance waiting position is in front of the card inlet of the card slot, the card pushing head can be paused at this position according to the sensing signal of the first card pushing sensor, without interfering with the operation of the card stacking device, and the card pushing action can be started quickly after the card stacking and card dialing are completed; in addition, the card pushing arm rotates and retracts under the guidance of a circle of rotating grooves, and the rotating groove has a recessed portion next to the card stacking entrance waiting position, so the card pushing head can also retract at this position, further avoiding interference with other components on both sides.

[0211] Furthermore, since the predetermined card raising entrance waiting position is in front of the card outlet of the card slot, the card pushing head can be paused at this position, that is, paused on the outside of one end of the supporting plate according to the sensing signal of the second card pushing sensor, which not only prevents it from interfering with the rotating card raising action of the supporting plate, but also limits the number of piles of cards pushed onto the supporting plate, preventing them from sliding off the supporting plate and affecting the number of mahjong tiles raised to the table.

[0212] Furthermore, one side of the card pushing head has two non-coplanar first card pushing surfaces and a second card pushing surface, and the card slot has a lower card slot and an upper card slot with a larger relative motion radius. Therefore, through the cooperation of the first card pushing surface and the upper card slot, and the second card pushing surface and the lower card slot, the lower layer of mahjong tiles in the card slot can always be pushed onto the table in a motion state slightly lagging behind the upper layer of mahjong tiles. Since the friction between the lower layer of mahjong tiles and the table is significantly greater than the friction between the two layers of mahjong tiles, through such a design, after the two layers of mahjong tiles are put on the table, the upper layer of mahjong tiles can slide a relatively farther distance, so that the two layers of mahjong tiles on the table are aligned, which gives users a better viewing experience and does not require manual alignment of the tiles, which is also more convenient.

[0213] The above embodiments are only used to illustrate the specific implementation methods of the present invention, and the present invention is not limited to the description scope of the above embodiments. Technical personnel in this industry should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.

[0214] For example, in the above embodiment, the first card-lifting sensing part 58 and the second card-lifting sensing part 59 are both magnets, and the first swing sensor 61 and the second swing sensor 62 are corresponding magnetic induction sensors. In the present invention, as long as the corresponding coordination between the first swing sensor 61 and the first card-lifting sensing part 58 and the corresponding coordination between the second swing sensor 62 and the second card-lifting sensing part 59 can be achieved, other sensors and sensing parts can also be used: for example, the first card-lifting sensing part 58 and the second card-lifting sensing part 59 can be set as a concave hole and / or a convex column with a specific depth or height, and the first swing sensor 61 and the second swing sensor 62 are both set as distance sensors, and it is judged whether the sensing part has reached the bottom according to the sensed distance signal.

[0215] Similarly, in the above embodiment, the card pushing sensing part is a magnet, and the first card pushing sensor 461 and the second card pushing sensor 462 are corresponding magnetic induction sensors. In an alternative scheme, other sensors and sensing parts can also be used. For example, a card pushing sensor can be set on one side edge of the card pushing rotating seat 42 (for example, set at the position of the sensing part mounting hole 425 shown in the above figure), and the card pushing sensor is set as a distance sensor. The first card pushing sensing part and the second card pushing sensing part are correspondingly set below the card pushing rotating seat 42 (for example, respectively set at the positions of the first card pushing sensor 461 and the second card pushing sensor 462 shown in the above figure). For example, the first card pushing sensing part and the second card pushing sensing part can be set as concave holes and / or convex columns with a specific depth or height, and the positions of the first card pushing sensing part and the second card pushing sensing part are respectively set corresponding to the above-mentioned stacking card entrance waiting position P1 and the lifting card entrance waiting position P2. The card pushing sensor (distance sensor) can judge whether it has reached the card pushing sensing part and which card pushing sensing part has been reached according to the sensed distance. When the push card rotating seat 42 rotates to the point where the push card sensor thereon senses the first push card sensing portion, the push card head 431 is located at the card stacking entrance waiting position P1; when the push card rotating seat 42 rotates to the point where the push card sensor thereon senses the second push card sensing portion, the push card head 431 is located at the card raising entrance waiting position P2, and the push card motor 44 is controlled according to the corresponding sensing signal. This can also achieve similar technical effects.
