The height of the tile feeding system is basically level with that of the tile lifting system, so that although the height of the host is reduced, the arrangement position of the tile lifting system can cause interference to the large-disc shuffling and the tile feeding system for sucking the mahjong tiles, and the tile lifting system is only suitable for small mahjong tiles. In addition, the arrangement of the tile outlet of the tile feeding system and the tile inlet of the tile feeding track is unreasonable, the tile pushing device does not have the tile stacking function, and the mahjong tiles are automatically stacked on the tile bearing table board, so that the mahjong tiles are not stacked neatly and are easy to move and misplaced, and the mahjong tiles cannot enter the tile feeding track, and generate faults such as confusion in the tile feeding track. In addition, after the horizontal card feeding rail is adopted, mahjong tiles close to the card outlet of the card feeding rail are very easy to fall from the card outlet back to the shuffling large tray; the adoption of the chain and the flag wheel structure has high noise.

However, since the card storage rail is passed over the conveying section of the card feeding device, the height of the main body of the mahjong machine is high (the height of the card feeding device and the height of the card feeding device are overlapped), and in addition, the L-shaped card storage rail is short, so that the universality is poor.

The automatic mahjong machine disclosed in patent documents with publication numbers CN103861280a and CN104645608A also has the problems of higher height of the main machine (height superposition of the card feeding device and the card feeding device), shorter L-shaped card storage track, and the like. In addition, after the horizontal card feeding rail is adopted, mahjong tiles close to the card outlet of the card feeding rail are very easy to fall from the card outlet back to the shuffling large tray; the steel wire rope is adopted to drive the card feeding pushing head to move, and the steel wire rope and the side wall of the track are severely rubbed, so that the service life is low.

The card feeding driving mechanism may have various forms, such as a link transmission mechanism, a gear transmission mechanism, a cam transmission mechanism, etc., as shown in fig. 1 and 2, and the card feeding driving mechanism includes a first gear 508, a second gear 505, a first link 504, a second link 506, a first card feeding push rod 503 and a second card feeding push rod 507, where the first gear 508 and the second gear 505 are respectively mounted on the card feeding support 501 and engaged with each other for transmission, the first gear 508 or the second gear 505 is in driving connection with a driving motor, one end of the first link 504 is hinged with the first gear 508, the other end of the first link 504 is hinged with the first card feeding push rod 503, one end of the second link 506 is hinged with the second gear 505, and the other end of the second link 506 is hinged with the second card feeding push rod 507. Therefore, the two card feeding push rods do reciprocating motion and mutually matched alternate card pushing are realized, the structure is simple and reasonable, the existing structural layout is utilized to the greatest extent, the manufacturing cost is reduced, and the reliability of products is ensured.

In this embodiment, as shown in fig. 2, the first gear 508 is disposed below, the first link 504 is disposed in the middle, the first card-feeding putter 503 is disposed above, the second gear 505 is disposed below, the second link 506 is disposed in the middle, the second card-feeding putter 507 is disposed above, and the card-feeding swing lever 513 is disposed above the second card-feeding putter 507. The swing ends of the first card feeding push rod 503 and the card feeding swing rod 513 are higher than the height of the inner side wall of the card storage groove 502. Thus, the mutual interference of the gear link mechanisms is avoided, and the height increase of the mahjong machine main machine is reduced as much as possible.

In order to avoid and ensure a larger card pushing force, the first card feeding push rod 503 and the second card feeding push rod 507 are bent arms (or L-shape), and taking fig. 1 as an example, the card storage slot is used for feeding cards clockwise, and the first card feeding push rod 503 and the second card feeding push rod 507 are bent clockwise. The first connecting rod and the second connecting rod are respectively provided with an avoidance groove for avoiding the fixed position (rotating fulcrum) of the upper card push rod.

The shape of the reversing groove can be various, and in this embodiment, the second card-feeding pusher can be switched from the contracted state to the expanded state in the reversing groove, so the reversing groove is not limited to a groove in a conventional sense, and can be an open accommodating space. For the gap between the card storage groove and the reversing groove, the second card-feeding push head 5131 in the vertical state can be freely moved in and out, and the mahjong pieces in the card storage groove are prevented from being embedded into the gap. The shape of the retraction groove may be various, and in this embodiment, the second card-feeding pusher may be moved from outside the card-discharging opening of the card-storing groove to the reversing groove along the retraction groove, so that the retraction groove is not limited to the groove in the conventional sense, but may be an open-type accommodation space.

The card slot is generally U-shaped, can be formed by a plurality of arc-shaped bending sections and a plurality of straight line sections, and can also be a large arc-shaped bending section as shown in CN204699375U, but the size of the table top of the mahjong machine is increased. In this embodiment, the card storage slot has two curved sections, which are respectively adapted to the rotational paths of the two card-feeding pusher heads. The outside of the card inlet and the outside of the card outlet of the card storage groove are both provided with sensors for detecting whether the card feeding push head moves in place, and the sensors can be Hall sensors or photoelectric sensors.

In order to reduce the friction resistance between the mahjong pieces and the bottom of the mahjong storage groove and not to increase the cost greatly, the bottom of the mahjong storage groove is provided with a mahjong storage groove bottom patch, and the mahjong storage groove bottom patch is preferably made of a material with smooth and wear-resistant surface, such as polyoxymethylene, polytetrafluoroethylene and the like. The card storage groove bottom patch is used as an independent component to be arranged in the card storage groove of the card loading support, and the card loading support is made of materials with poor performance and low price, so that the card storage groove bottom patch can meet the use requirement, and the manufacturing cost of a machine can be reduced. The patch at the bottom of the card storage tank is preferably matched and positioned with the card feeding bracket through a plurality of buckles and locked and fixed through fasteners so as to be convenient to install. Similarly, in order to reduce frictional resistance between the mahjong pieces and the inner side wall and the outer side wall (particularly the side wall of the arc-shaped bending section) of the mahjong storage tank, and at the same time, the cost is not greatly increased, part or all of the inner side wall and/or the outer side wall of the mahjong storage tank is provided with side wall patches, and the side wall patches are preferably made of materials with smooth and wear-resistant surfaces, such as polyoxymethylene, polytetrafluoroethylene and the like.

The mahjong tile storage groove can be made into a slope form with a gentle slope from the mahjong tile inlet to the mahjong tile outlet, but the tile pushing resistance of the mahjong tile pushing head is increased in this way. In addition, the card storage groove is provided with a slope, so that the card lifting assembly can further prolong the length of the card lifting supporting plate in the card lifting assembly and slow down the inclined slope of the card lifting supporting plate, and the card feeding resistance is reduced. The tile discharging slope can be formed at the bottom of the tile storing tank, but is preferably arranged on a tile storing tank bottom patch, namely, most of the tile storing tank bottom patch is horizontally arranged, and the tile discharging slope capable of lifting the mahjong tiles is formed at the tile discharging opening close to the tile storing tank bottom patch. The tile feeding slope surface which is convenient for the mahjong tile to enter is formed at the tile feeding opening of the tile storage tank bottom patch. In order to avoid the occurrence of the faults of arching, jumping and the like in the mahjong tiles in the tile storage groove during the tile pushing process of the tile pushing device, a tile pressing plate for limiting the tile storage height of the tile storage groove is arranged above the tile storage groove on the tile feeding support 501, and covers part or all of the top of the tile storage groove.

In order to prevent the mahjong tiles on the table top of the mahjong machine from being shifted up and down, the horizontally moving second mahjong tile pushing head 5131 is provided with a plurality of tile pushing parts which are respectively contacted with two mahjong tiles which are overlapped up and down in the same pier, wherein the tile pushing parts contacted with the lower mahjong tile are protruded out of the tile pushing parts contacted with the upper mahjong tile, thus, when the second mahjong tile pushing head 5131 pushes the mahjong tiles on the plurality of piers to horizontally move, the mahjong tiles on the upper layer are behind the mahjong tiles on the lower layer, and when the second mahjong tile pushing head 5131 pushes the last mahjong tile on the inclined mahjong tile lifting supporting plate, the mahjong tiles on the upper layer are flush with the mahjong tiles on the lower layer.

In order to facilitate the second card-feeding pushing head to move to the inside of the retreating groove outside the card outlet of the card storage groove, an opening for the second card-feeding pushing head to enter and exit is arranged on the inner side wall of the card-feeding groove in the card-feeding component, and meanwhile, in order to enable mahjong pieces to fall out or be clamped from the opening, a turning plate capable of being opened and closed is covered on the opening, and one side of the turning plate is hinged with the card-feeding bracket and is closed through a torsion spring.

As shown in fig. 14, 15 and 16, in order to avoid collision between the first card feeding pusher and the card pushing head 401 in the card pushing device outside the card feeding port of the card storage slot and avoid blocking of the mahjong tiles sent by the card feeding device, the first card feeding pusher 5033 and the card pushing head 401 in the card pushing device adopt a dislocation avoiding design, and are arranged on one side of the card bearing table 402 together with the card pushing head 401 before feeding. In order to avoid the disorder and card easily caused by the mahjong tile pushing device, as shown in fig. 9, the tile inlet of the tile storage groove is arranged at an included angle of 80-100 degrees with the tile outlet of the tile feeding device, and the tile pushing direction of the tile pushing head 401 of the tile pushing device 4 is matched with the tile inlet of the tile storage groove.

In the card picking and carrying system, the matching relationship among the card storage groove in the card loading assembly, the card bearing table in the card pushing device and the conveying channel in the card conveying device is particularly important, and the action process of the card pushing device is determined.

In one embodiment of the present invention, as shown in fig. 17 to 20, the card slot has a card inlet height lower than the card outlet height of the card delivery device and a height difference M between them greater than the height of one mahjong tile and less than the height of two mahjong tiles, preferably 21 to 33 cm. Thus, as shown in fig. 17, the deck 402 receives the first mahjong tile 10 at an initial position slightly below the tile outlet of the tile feeding device; and then descends by one height to receive a second mahjong tile, at this time, the height of the tile receiving platform is close to that of the tile inlet of the tile storage groove, as shown in fig. 18 and 19, and then the stacked mahjong tile pier is pushed into the tile inlet of the tile storage groove 502 by the tile pushing head 401, as shown in fig. 16 and 20. Finally, the deck 402 is raised to the initial position, waiting for the next mahjong tile as shown in fig. 17.

In another embodiment of the present invention, as shown in fig. 21 to 25, the card slot has a card inlet height lower than the card outlet height of the card delivery device and a height difference M between them smaller than the height of one mahjong tile, preferably 1 to 13 cm. Thus, as shown in FIG. 21, the deck 402 receives the first mahjong tile 10 at an initial position slightly below the outlet of the card delivery device; lowering the first mahjong tile to a height to receive a second mahjong tile, as shown in fig. 22 and 23; then the deck 402 is raised to the initial position, where the deck is at a level close to the card slot entrance, as shown in fig. 24; the piled mahjong pieces are pushed into the mahjong inlet of the mahjong storage groove 502 by the mahjong pushing head 401, and after the mahjong pushing head 401 retreats, the next mahjong pieces are waited for.

The two embodiments can lead the actions of the card bearing table and the card pushing head in the card pushing device to be simple and reasonable and lead the reliability to be better. Because the tile feeding push rod is required to be arranged above the mahjong tiles in the tile storage groove, the height of the tile feeding assembly is increased, when the height of the tile feeding assembly influences the whole height of the mahjong machine main machine, the first embodiment can be adopted, and the height of the tile feeding assembly can be reduced. In the second embodiment, the difference between the height of the card inlet and the height of the card outlet of the card storage groove is small, and the card storage groove structure which is basically horizontal is adopted, so that the problem of increasing the card resistance is solved.
