The mahjong tile is also called sparrow tile (also called horse hanging), which is a game invented by ancient Chinese people, and the tile entertainment appliance is made of bamboo, bone or plastic, on which patterns or words are carved, and is a game attended by four people, and the rules of the game in different areas are slightly different. A set of mahjong tiles comprises 3 basic colors of ten thousands, cakes and strips, which are called: mo Zi cards (ten thousands), cone cards (cakes) and strip cards (ropes), 4 cards from one to nine, and twenty-seven 108 cards in total; and 4 cards of east, south, west, north, middle and white are added, and seven 28 cards are added; 136 cards in total, which is also called as 'plain mahjong' in normal times. Then, eight cards with similar functions to the king (JOKER) in the playing cards are added, namely: "spring, summer, autumn, winter, plum, blue, bamboo, chrysanthemum" and one hundred forty-four cards, which form what we said "mah-jongg with flowers". And 8 wild cards are arranged. Thus, a complete deck of mahjong tiles (74 tiles in some areas) includes words, flowers, ordinal numbers, and wild cards. The popular is simplified mahjong, which does not contain wild cards and large white boards, and has 144 pieces. Compared with other domino forms, the playing method of the mahjong is the most complex and interesting, the basic playing method is simple and easy to get on hand, but the variation is very large, and the matching combination is different from person to person, so the mahjong becomes one of the most attractive domino forms in China historically.

Along with the continuous improvement of the standard of living, people pay more attention to leisure, entertainment and life, and the convenient and labor-saving automatic mahjong machine is gradually favored by people.

Because the existing four-port automatic mahjong machine is limited by the structure of the pushing and lifting mechanism, two mahjong tiles are stacked together to be played when the mahjong tiles are pushed and lifted, and only one row of mahjong tiles is arranged in front of each person on the table top.

In the slope tile discharging device, two groups of tile feeding components can be selected to be used for respectively pushing the mahjong tiles on the first tile storage groove 41 and the mahjong tiles on the second tile storage groove 42, each group of tile feeding components comprises a tile feeding swing rod and a tile feeding motor, the tile feeding motor drives the tile feeding swing rod to rotate along one end of the tile feeding swing rod, the other end of the tile feeding swing rod skips the tile storage groove to push the mahjong tiles, and two groups of tile feeding components are adopted to push the mahjong tiles respectively, on one hand, two groups of driving motors are required to be arranged for driving, and the structure is complex and the cost is high; on the other hand, whether the swinging paths of the two card feeding swinging rods are staggered or matched with the card feeding bracket and the card storage groove is considered. In addition, referring to the technical solution described in CN108096828a, a card pulling assembly is provided in each of the first card storage slot 41 and the second card storage slot 42, and the card pulling assembly includes a card pulling head that moves along the track direction of the first card storage slot 41 or the second card storage slot 42, and the card pulling head may be driven by a wire rope or by a belt using a card pulling motor, as in the patent document CN108096828 a. Of course, the two schemes can be combined, namely, a card feeding swing rod is adopted when the first card storage groove 41 pushes cards, and a card pulling head is adopted when the second card storage groove 42 pushes cards; or in contrast to both schemes.

In the embodiment shown in the figures, the slope card discharging device adopts the same card feeding assembly, and the card feeding assembly comprises a first card feeding swing rod, a second card feeding swing rod and a card feeding motor, wherein the first card feeding swing rod and the second card feeding swing rod are coaxially and rotatably arranged and are driven by the card feeding motor. As described above, the first card storage slot 41 is located below the second card storage slot 42, and a gap is left between the top of the first card storage slot 41 and the bottom of the second card storage slot 42, so that the first card feeding swing rod extends into the first card storage slot 41 to push cards. The track path of the first card storage groove 41 is C-shaped, and the first card storage groove 41 is arc-shaped with the rotation axis of the first card feeding swing rod as the center of a circle; the track path of the second tile storage groove 42 is in a J shape, the J shape comprises an arc section 421 and a straight line section 422, the arc section 421 is positioned in front of the straight line section 422, namely, the head end of the straight line section 422 is connected with the tail end of the arc section 421, the arc section 421 is overlapped with the radian of the first tile storage groove 41, and the edge of the straight line section 422, attached to the frame 1 of the mahjong machine, is positioned on the same straight line with the second tile lifting supporting plate 46 and the second tile lifting opening. When the first tile feeding swing rod and the second tile feeding swing rod are driven by the tile feeding motor to rotate, the first tile feeding swing rod pushes the mahjong tiles to the first tile lifting supporting plate 45 along the track of the first tile storage groove 41, and the mahjong tiles are lifted to the tabletop after the first tile lifting supporting plate 45 is lifted; the second tile feeding swing rod pushes the mahjong tiles onto the second tile lifting support plate 46 along the track of the second tile storage groove 42, and the mahjong tiles are lifted onto the table surface after the second tile lifting support plate 46 is lifted. In the above-mentioned scheme, in order to realize that the second tile feeding swing link completely pushes the mahjong tile onto the second tile lifting support plate 46, the movable end of the second tile feeding swing link needs to pass through the end of the straight line segment 422 of the second tile storage groove 42, so as to ensure that no mahjong tile remains in the second tile storage groove 42 after the second tile feeding swing link passes. In addition, in the above scheme, it is pointed out that the first card storage slot 41 is located below the second card storage slot 42, and the second card storage slot 42 is located above, at this time, the relative position of the second card storage slot 42 is higher, and the swing angle of the second card lifting supporting plate 46 is smaller, so that too much avoiding space is not needed in the frame 1 due to the smaller swing angle; the track card distributor disclosed in the Chinese patent publication No. CN 208694238U comprises a first sub-track, a second sub-track and a card pushing mechanism, wherein the first sub-track is used for sequentially conveying mahjong tiles to be grasped, separated from the main track, to the card grabbing area in order, the second sub-track is used for sequentially conveying mahjong tiles to be dealt, separated from the main track, to the card discharging area in order, and the card pushing mechanism is used for pushing the mahjong tiles. In the scheme, the second sub-track and the tile pushing mechanism are required to be arranged because the conveying track of the mahjong tiles to be played is arranged below, so that a larger avoiding space is formed to realize the lifting of the tile lifting supporting plate at a larger angle. In addition, in the scheme, the inclined angle of the second tile lifting supporting plate 46 is relatively smaller when the mahjong tiles are received, so that the mahjong tiles cannot slide downwards due to the fact that the inclined angle is too large in the lifting process of the second tile lifting supporting plate 46. In another equivalent embodiment, the tile feeding assembly comprises a tile feeding swing rod 47, a tile feeding motor for driving the tile feeding swing rod 47 to swing, and a tile feeding push head connected to the movable end of the tile feeding swing rod 47, wherein the tile feeding push head comprises a first tile feeding part and a second tile feeding part, the first tile feeding part pushes the mahjong tile onto the first tile lifting support plate 45 along the track of the first tile storage groove 41, and the second tile feeding part pushes the mahjong tile onto the second tile lifting support plate 46 along the track of the second tile storage groove 42, and the second tile feeding part passes through the tail end of the straight line section 422 of the second tile storage groove 42. The scheme is that the first card feeding swing rod and the second card feeding swing rod which are coaxially and rotatably arranged in the scheme are combined into one card feeding swing rod 47, and two card feeding parts are arranged to meet the card feeding requirements of the first card storage groove 41 and the second card storage groove 42.

In the card picking and transporting system, the track path of the first card storage slot 41 is in a shape of a C, the first card lifting support plate 45 is received at the track end of the first card storage slot 41, the track path of the second card storage slot 42 is in a shape of a J, and the second card lifting support plate 46 is received at the end of the straight line segment 422 of the second card storage slot 42; thus, the mahjong tiles conveyed by the first tile storage groove 41 in the tile picking and conveying system are conveyed to the first tile lifting opening at the front side, and the mahjong tiles conveyed by the second tile storage groove 42 are conveyed to the second tile lifting opening adjacent to the first tile lifting opening in the anticlockwise direction. Similarly, in an automatic mahjong machine, four sets of pick-up and delivery systems are located on four sides of the shuffling tray, with the mahjong tiles delivered from the first storage slot 41 of each set of pick-up and delivery systems being in front of the player on that side and the mahjong tiles delivered from the second storage slot 42 of each set of pick-up and delivery systems being in front of the player on the downstream side.

The main innovation point of the mahjong machine is that: under the action of an existing three-layer mahjong machine, a mahjong feeding device 2 of the mahjong machine is divided into an upper mahjong carrying area 311 and a lower mahjong carrying area 312, a first mahjong storage groove 41 and a second mahjong storage groove 42 are adopted in a corresponding slope mahjong discharging device, the first mahjong storage groove 41 receives mahjong tiles of two stacks sent out by the lower mahjong carrying area 312, and the second mahjong storage groove 42 receives single-layer mahjong tiles sent out by the upper mahjong carrying area 311; in order to simplify the card feeding structure, the second card storage groove 42 is arranged above the first card storage groove 41, so that the swing angle of the second card lifting supporting plate 46 is smaller, and the inclination angle during carrying is also smaller, so that too much avoidance space is needed; the card lifting can be realized by adopting a single card feeding assembly; has the functions of simplifying the structure and improving the efficiency.

When the mahjong machine works, the mahjong pieces on the shuffling large disc are respectively shifted to the positions below the feeding ports of the four mahjong delivery devices 2 at the edge of the shuffling large disc, the mahjong pieces are sucked up by the mahjong suction wheels in the mahjong delivery devices 2 and are straightened to be in the same direction, then are delivered to the mahjong delivery channel, and are delivered to the mahjong piece 31 in the stacking and pushing device 3 through the delivery port of the mahjong delivery channel, one mahjong piece of three mahjong pieces continuously delivered in the mahjong delivery device 2 is pushed into the upper mahjong piece bearing area 311 of the mahjong piece bearing block 31, the other two mahjong pieces of mahjong pieces are pushed into the lower mahjong piece bearing area 312 of the mahjong piece bearing block 31 and are stacked into a pier position, and the bearing sequence of the upper mahjong piece bearing area 311 and the lower mahjong piece bearing area 312 can be adjusted according to requirements, and the adjusting scheme is based on the matched action process of the mahjong piece bearing cam 34 and the pushing slider 37; then, the upper tile pushing head 361 in the stacking pushing device 3 pushes the mahjong tiles in the upper tile bearing area 311 into the second tile storage groove 42, and the lower tile pushing head 362 pushes the mahjong tiles in the lower tile bearing area 312 into the first tile storage groove 41; the above-described stacking step is repeated so that a signal for feeding a mahjong tile is waited when enough mahjong tiles are stored in the first tile storage groove 41 and the second tile storage groove 42. After receiving the card feeding signal, the movable end of the first card lifting support plate 45 descends to be connected with the tail end of the track of the first card storage groove 41, and the movable end of the second card lifting support plate 46 descends to be connected with the tail end of the track of the second card storage groove 42; the first tile feeding swing rod and the second tile feeding swing rod are driven by the tile feeding motor to synchronously rotate, the first tile feeding swing rod pushes mahjong tiles onto the first tile lifting supporting plate 45 along the track of the first tile storage groove 41, and the second tile feeding swing rod pushes mahjong tiles onto the second tile lifting supporting plate 46 along the track of the second tile storage groove 42; after the first tile lifting supporting plate 45 and the second tile lifting supporting plate 46 are lifted, the mahjong tiles are lifted to the table top.

Based on the mahjong tile arranging method, the table top plate is provided with four first tile lifting openings and four second tile lifting openings, so that the table top plate is called an eight-opening machine; the mahjong tiles sent to the table top by the first tile lifting supporting plate 45 are mahjong tiles required for tile touching, and the mahjong tiles are formed by stacking two layers; the mahjong tiles sent to the table top by the first tile lifting supporting plate 45 are tiles sent to each player in an opening way and are single-layer.

The same as the embodiment, the embodiment also adopts an eight-port machine structure. Namely, the tabletop plate 12 of the stand 1 is provided with four first rising ports 13 for sending out mahjong tiles required by dealing and four second rising ports 14 for sending out mahjong tiles required by dealing. Four first card lifting openings 13 are positioned in the middle of the table top 12 and are arranged around the central control panel assembly 11. The first card lifting port 13 is similar to the card lifting position of the currently adopted four-port machine, the first card lifting port 13 in the scheme is obliquely arranged relative to the edge of the tabletop, the distance between the left side end of the first card lifting port 13 and the edge of the tabletop is smaller than that between the right side end of the first card lifting port 13 and the edge of the tabletop, and the left and right ends are judged in the direction of the user at the side; therefore, the space operation space in the right front of the user is larger, and the method is suitable for handedness of most users. The four second card lifting ports 14 are respectively positioned at the four end edges of the tabletop plate 12 and are basically parallel to the tabletop plate edges; when the second tile lifting port 14 sends out the mahjong tiles, the user only needs to erect the mahjong tiles at the second tile lifting port, and the step of manually dealing in the traditional four-port machine is completed.

The card feeder 2 of this embodiment is the same as that of embodiment 1, and see patent document CN105413161A, CN106492454A, CN106669142a and the like.

The slope card discharging device in this embodiment is the same as the one in embodiment 1 in that the slope card discharging device includes a card feeding bracket and a card feeding assembly provided on the card feeding bracket. Wherein the card holder comprises a first card slot 41 capable of receiving two stacks of mahjong tiles from the outlet of the stacking and pushing device 3, and a second card slot 42 for receiving a single layer of mahjong tiles from the outlet of the stacking and pushing device 3. The difference is that in this embodiment, the upper tile holding area 311 of the stacking and pushing device 3 is used for holding two stacks of mahjong tiles, and the lower tile holding area 312 is used for holding a single-layer mahjong tile. Thus, the first tile storage slot 41, which receives two stacks of tiles, is above the second tile storage slot 42, which receives a single layer of tiles. In this embodiment, the card feeding assembly specifically includes a first card feeding assembly and a second card feeding assembly. Wherein, the first tile feeding assembly pushes two stacks of mahjong tiles in the first tile storage groove 41 to the first tile lifting opening 13 along the inclined plane; the second tile feeding assembly pushes the single-layered mahjong tile in the second tile storage slot 42 along the inclined surface to the second tile lifting opening 14. That is, in this embodiment, the first card raising port 13 and the second card raising port 14 are each configured to carry out card discharge by using a slope card raising method.

In a specific embodiment, as shown in fig. 1 in example 1, the conveying direction, that is, the starting end to the end of the first card storing groove 41 and the second card storing groove 42 are arranged along the anticlockwise direction of the shuffling tray, the starting end and the end of the first card storing groove 41 are positioned in front of players on the same side, and the end of the second card storing groove 42 is positioned in front of players on the anticlockwise downstream of the starting end.

By adopting the scheme, the first mahjong storage groove 41 conveys mahjong tiles along the anticlockwise direction of the shuffling large tray, and in order to enable the starting end and the tail end of the first mahjong storage groove 41 to be positioned in front of players on the same side, the first mahjong storage groove 41 is required to be turned by more than or equal to 180 degrees, and then the circular arc-shaped first mahjong storage groove 41 can be used for feeding the mahjong tiles in a swinging rod pushing mode. In a specific scheme, the first card feeding assembly comprises a card feeding motor and a card feeding swing rod, wherein one end of the card feeding swing rod is connected to the output end of the card feeding motor; the movable end of the tile feeding swing rod pushes the mahjong tiles along the track of the first tile storage groove 41. In addition, in the above scheme, it is described that the two stacked mahjong tiles in the first tile storage groove 41 are pushed to the first tile lifting opening 13 along the inclined plane, so that the slope tile discharging device further comprises a tile lifting assembly, the tail end portion of the first tile storage groove 41 is connected with a first tile lifting bracket 43, and the tile lifting assembly can be specifically structured according to the tile lifting structure in the chinese patent application filed by the applicant in the future and having application number of 2019200586016, and comprises a first tile lifting supporting plate 45 with one end hinged on the first tile lifting bracket 43, and a tile lifting driving assembly for driving the first tile lifting supporting plate 45 to move along the hinged end of the first tile lifting supporting plate. The first card lifting support plate 45 can swing within a certain range relative to the first card lifting support 43 along the hinged end, and when the movable end of the first card lifting support plate 45 is positioned at the lowest end of the swinging path, the first card lifting support plate 45 is accepted with the track tail end part of the first card storage groove 41; when the movable end of the first card lifting pallet 45 is at the uppermost end of the swing path, the first card lifting pallet 45 is in a horizontal state and closes the first card lifting port 13.

In another specific embodiment, referring to fig. 12 and 13, the conveying direction of the first card slot 41 and the second card slot 42, that is, the starting end to the end, is clockwise along the shuffling tray; the terminal portions of the first and second card slots 41, 42 are located on the downstream player front side in the clockwise direction of the start ends thereof. In the drawings of the embodiment, the track path of the first tile storage groove 41 is in a J shape, and the first tile storage groove 41 comprises a starting section which is attached to the edge of the frame 1 and an arc-shaped section which is turned from the tail end of the starting section to the lower part of the first tile lifting opening 13 in the middle of the mahjong machine. Since the first card storing groove 41 and the second card storing groove 42 in this embodiment are both in a "J" shape, rather than in a circular arc shape, the first card feeding assembly cannot be pushed by the swing lever in the above-described embodiment. In this embodiment, the first card feeding assembly includes a first card feeding pusher 481 and a first traction assembly for driving the first card feeding pusher 481 to reciprocate along the track direction of the first card storage slot 41. The first traction component is a traction pull rope 482 which is arranged along the track direction of the first mahjong storage groove 41, and a synchronous belt, a steel wire rope or a chain can be adopted, and the specific implementation scheme can be respectively disclosed by patent document with publication number CN201783185U, and the chain for the full-automatic mahjong machine drives a slope mahjong discharging device; or an automatic mahjong machine disclosed in patent documents with publication numbers of CN103861280A and CN104645608A, which discloses a scheme for realizing the feeding by driving a feeding pushing head to move by adopting a steel wire rope. Similarly, in this embodiment, the end portion of the first card slot 41 is connected to a first card lifting support 43, and the specific structure of the card lifting assembly may be referred to as a card lifting structure in the chinese patent application filed by the applicant in the future and filed under the application number "2019200586016", and the card lifting assembly includes a first card lifting support 45 with one end hinged to the first card lifting support 43, and a card lifting driving assembly driving the first card lifting support 45 to move along the hinged end thereof. The first card lifting support plate 45 can swing within a certain range relative to the first card lifting support 43 along the hinged end, and when the movable end of the first card lifting support plate 45 is positioned at the lowest end of the swinging path, the first card lifting support plate 45 is accepted with the track tail end part of the first card storage groove 41; when the movable end of the first card lifting pallet 45 is at the uppermost end of the swing path, the first card lifting pallet 45 is in a horizontal state and closes the first card lifting port 13.

Based on the layout structure of the first card slot 41 and the specific structure of the first card feeding assembly adopted by the first card slot 41 in the above two schemes, the present embodiment is different from the background technical scheme in that the second card slot 42 adopts a passive card feeding scheme. The embodiment 1 adopts the scheme that the mahjong tiles in the first tile storage groove 41 are pushed by the swing rod pushing mode, and the mahjong tiles in the second tile storage groove 42 are also pushed at the same time. As shown in fig. 1 of embodiment 1 and fig. 12 of the present embodiment, the second card slot 42 is in the shape of a "J" with the only difference being that the second card slot 42 is for feeding cards in a clockwise or counterclockwise direction along the shuffling tray. However, in any case, the second card slot 42 is suitable for the following embodiments, in a specific embodiment, the end portion of the second card slot 42 is provided with a card lifting inclined surface connected to the second card lifting opening 14, unlike in example 1, the card lifting inclined surface 491 in this embodiment is fixedly received on the end of the first card slot 41, and the second card lifting supporting plate in example 1 adopts a slope manner that one end is hinged and the other end is liftable. In this embodiment, since the tile lifting ramp 491 is fixedly disposed, the mahjong tile lifting mechanism is not provided, and the mahjong tile is forced to push the tile lifting ramp 491 through the second tile lifting assembly and is delivered to the table top 12 through the second tile lifting opening 14. Considering the use condition, the passive tile feeding mode is generally used as a tile feeding structure of a single-layer mahjong tile, and landslide and dislocation of the upper-layer mahjong tile are easy to occur when the double-layer mahjong tile is pushed by an inclined plane. Meanwhile, the slope of the tile lifting inclined plane 491 should be considered, too small slope can make the tile lifting inclined plane 491 longer and occupy the space of the mahjong machine, and too large slope can cause the mahjong tiles to be difficult to push onto the tabletop 12; the angle shown in the drawings of this embodiment is 36 deg., but should be adjustable within the appropriate angle as required by the person skilled in the art. In addition, in order to facilitate the pushing of the mahjong tiles onto the table top 12 by the tile lifting inclined surface 491, the second tile storage groove 42 can be gradually lifted along the feeding direction. In a specific embodiment, the second card feeding assembly includes a card feeding pushing assembly and a second traction assembly that drives the card feeding assembly to move along the track direction of the second card slot 42; the card feed pusher assembly is longitudinally adjustable relative to the depth of the second card slot 42. Wherein, the second traction component is arranged along the track direction of the second mahjong storage groove 42, and is consistent with the first traction component, and a synchronous belt, a steel wire rope or a chain can be adopted, and the specific implementation scheme can be respectively seen from patent document with publication number CN201783185U to disclose a slope mahjong machine chain driving device; or an automatic mahjong machine disclosed in patent documents with publication numbers of CN103861280A and CN104645608A, which discloses a scheme for realizing the feeding by driving a feeding pushing head to move by adopting a steel wire rope. In the drawings of this embodiment, the second traction assembly is a chain 401, which may be driven by a drive motor through gears. As shown in the figure, the card-feeding pushing assembly includes a sliding column 402, a card-feeding pushing block 403, and a sliding seat 404; the sliding column 402 is arranged on the second traction assembly in a penetrating manner in the depth direction of the second card storage groove 42, the card feeding push block 403 is connected to the sliding column 402 above the second traction assembly, and the sliding seat 404 is connected to the sliding column 402 below the second traction assembly; the sliding column 402 can move along the axial direction relative to the second traction assembly, and a spring 405 is arranged between the sliding column 402 between the second traction assembly and the sliding seat 404; a sliding rail which is matched with the sliding seat 404 and adjusts the height of the sliding seat 404 is arranged below the second card storage groove 42. In the embodiment shown in fig. 14, a linear through hole 423 is formed in the middle of the bottom of the second card slot 42 along the track direction, the card feeding push block 403 extends out of the linear through hole 423, and the sliding column 402, the spring 405 and the sliding seat 404 below the card feeding push block 403 are all located below the second card slot 42. The sliding track can be completely consistent with the track direction of the second card storage groove 42, or can be completely consistent with the height adjusting section of the second card storage groove 42. The sliding seat 404 may be in a smooth fit with the sliding rail, or in a rolling fit, for example, a roller may be installed on the sliding seat 404, or a ball may be embedded on the sliding rail.
