Technical Field

[0001] The utility model relates to the field of mahjong machine manufacturing, in particular to a mahjong machine and a horizontal push card loading device and a card supporting plate transmission mechanism thereof. Background Art

[0002] Mahjong is a popular intellectual game. After a round, players must shuffle the cards, a tedious and time-consuming process. Consequently, mahjong machines capable of automatic shuffling have been invented. To reduce the size of mahjong machines, existing mahjong machines feature an arc-shaped pusher slot. This reduces the overall size of the machine by minimizing the size of the pusher mechanism. Mahjong machines are equipped with a pusher mechanism and a lift mechanism. The pusher mechanism pushes the tiles onto the lift mechanism, which then lifts the tiles onto the tabletop.

[0003] The patent technical document with publication number CN219149198U discloses a mahjong machine and its push-up card loading device and card supporting plate transmission mechanism, wherein the push-up card loading motor pushes the card loading swing arm through the card loading connecting rod to drive the card loading rocker arm shaft to rotate, and the card loading rocker arm shaft rotates through the card loading rocker arm fixed on it, and the card loading rocker arm rotates and pushes the card loading curved cam fixed on the card supporting plate, thereby driving the card supporting plate to rise and fall.

[0004] In the prior art, a loading link is mounted on a loading housing via a loading link sleeve, and both ends of the loading link are connected to a loading drive cam and a loading swing arm, respectively. As there must be a certain gap between the loading link and the loading link sleeve, and the loading link itself is tilted, both ends of the loading link are movable, which results in the loading link and the loading link sleeve being worn out quickly in a short period of time during the use of the mahjong machine, thereby affecting the push-to-load action of the mahjong machine and the use effect of the mahjong machine.

Example

[0037] A mahjong machine includes a shuffling plate, a card scraper, and a central lifting device located in the center of a frame bottom plate.

Adjacent card feeding devices are connected by a connecting wall. The four card feeding devices in the four sets of card picking and transporting systems are connected end to end by the four connecting walls to form a shuffling frame and a shuffling barrel within which there is a shuffling space. The shuffling frame is arranged around the shuffling plate. The card inlet of the card feeding device is located on the inner wall of the shuffling frame, and the card outlet of the card feeding device is located on the outer wall of the shuffling frame. The four card feeding motors are mounted on the outer wall of the shuffling frame. The specific structure of the card feeding device can be found in patent documents such as publication numbers CN105363195, CN213965119U, CN206881091U, CN212941371U, CN108786098A, and CN205832557U.

[0039] The pusher device includes a receiving block for receiving mahjong tiles delivered by the delivery device and a pusher head for pushing the tiles on the receiving block to the horizontal pusher device. The receiving block and the pusher head are driven by a pusher motor. The specific structure of the pusher device can be found in patent documents such as CN201906453U, CN201949619U, CN103861280A, CN204699375U, CN209500734U, and CN112057840A.

[0040] In this embodiment, the card pushing device includes a card pushing housing, a card pushing motor is installed on the card pushing housing, a card pushing transmission mechanism is provided in the card pushing housing, a card receiving block and a card pushing head are provided outside the card pushing housing, the card pushing motor drives the card receiving block to move up and down through the card pushing transmission mechanism to stack mahjong tiles, and the card pushing motor drives the card pushing head to move horizontally through the card pushing transmission mechanism to push the stacked mahjong tiles from the card receiving block. In a preferred embodiment, the card pushing transmission mechanism includes a card pushing curve wheel, a translation slider, a lifting slider and a swing rod, the card pushing motor drives the card pushing curve wheel to rotate, the swing rod is hinged to the card pushing housing, one end of the swing rod is movably connected to the lifting slider, the swing rod is driven by the card pushing curve wheel to swing up and down, thereby driving the lifting slider to move up and down, the card receiving block outside the card pushing housing is fixedly connected to the lifting slider inside the card pushing housing through the card receiving block extension arm, the translation slider is driven by the card pushing curve wheel to translate left and right, and the card pushing head outside the card pushing housing is fixedly connected to the translation slider inside the card pushing housing through the card pushing head extension arm. Among them, the card pushing shell is provided with a lifting slider guide rod and a translation slider guide rod, the lifting slider rises and falls along the lifting slider guide rod, and the translation slider translates left and right along the translation slider guide rod. A card blocking block is provided on the outside of the card holding block, and the card outlet of the card feeding device and the card blocking block are respectively located on the inner and outer sides of the card holding block. A counting detection device for detecting the number of times the cards are pushed is installed on the card pushing shell; a card feeding detection device for detecting whether the card outlet of the card feeding device has delivered mahjong tiles to the card holding block is provided near the card holding block. A preferred embodiment is to set the card feeding detection device on the card blocking block. The counting detection device and the card feeding detection device are preferably photoeyes.

[0041] Push-on card loading device, such as Figures 1 to 6As shown, it includes a card holding plate 72 for holding and arranging multiple piles of mahjong tiles, a card supporting plate 74 for delivering multiple piles of mahjong tiles to the table at one time, and a card pushing plate 73 for pushing the multiple piles of mahjong tiles on the card holding plate 72 onto the card supporting plate 74. The card holding plate 72 is arranged on the card loading shell 70, the card supporting plate 74 is located on the inner side of the card holding plate 72, and the card pushing plate 73 is located on the outer side of the card holding plate 72 and pushes the tiles from the outside to the inside. A card storage channel for storing and arranging multiple piles of mahjong tiles is formed on the card holding plate 72. One end of the card holding plate 72 extending along the length direction is the card inlet of the card storage channel, and a card holding block of a card pushing device is provided outside the card inlet. The other end of the card holding plate 72 extending along the length direction is provided with a side baffle 721. The front and rear blocks of the card storage channel are respectively a front baffle 742 and a card pushing plate 73. The front baffle 742 is fixedly connected to or integrally formed with the card supporting plate 74. The card loading housing 70 is provided with a card loading transmission mechanism. A horizontal card loading motor 71 drives a card pushing plate 73 to push cards horizontally and a card supporting plate 74 to lift and lower cards via the card loading transmission mechanism. The mahjong tabletop is provided with four card loading openings. The four card supporting plates 74 in the four sets of card picking and transporting systems respectively cooperate with the four card loading openings. When the card supporting plates 74 are raised, they fill the card loading openings and become flush with the mahjong tabletop. The card loading transmission mechanism includes a card supporting plate transmission mechanism for driving the card supporting plates 74 to lift and lower, and a card pushing plate transmission mechanism for driving the card pushing plate 73 to push horizontally.

[0042] In a large windmill-shaped mahjong machine, a horizontal push loading device is tilted relative to the side of the table top on the same side. The card inlet end of the horizontal push loading device is positioned further inward than the other end. The mahjong tiles on all four sides of the mahjong machine are lifted onto the table top at once, tilted relative to the four edges of the table top and close to the center of the table top. By tilting the horizontal push loading device, the corresponding card loading port and the side of the table top on the same side are also tilted. When the mahjong tile wall rises to the table top, it is already tilted, eliminating the need for players to manually push the tiles, which is in line with their playing habits. Moreover, because the mahjong tile wall is pushed horizontally onto the card support board and then raised from the card support board to the table top, the problem of falling tiles does not occur.

[0043] In this embodiment, the card feeding motor of the card feeding device is preferably located below the card outlet of the card feeding channel. In this way, for a windmill-shaped mahjong machine, the card feeding motor is located closer to the corner of the mahjong table, which not only shortens the card feeding channel but also avoids interference with the horizontal card loading device, allowing the shuffling frame and shuffling plate to be larger.

[0044] In this embodiment, the card receiving block of the card pushing device is preferably disposed outside the shuffling frame. Therefore, the card outlet of the card feeding device and the card inlet of the card pushing device are also disposed outside the shuffling frame. This prevents the card receiving block from encroaching on the shuffling space when it descends, thereby maximizing the size of the shuffling frame and the shuffling plate.

[0045] This embodiment is preferred, as Figure 2 As shown, the card loading housing 70 of the horizontal push card loading device has its inner sidewall near the shuffling tray partially or completely hollowed out, allowing the edge of the shuffling tray to expand directly below the card receiving plate 72, and the card feeding motor of the card feeding device to extend directly below the card receiving plate 72. This allows the majority of the card supporting plate 74 and a small portion of the card receiving plate 72 to be positioned above the shuffling frame. This not only increases the size of the shuffling tray while effectively increasing the shuffling space, but also shortens the card feeding passage of the card feeding device, thereby making the positioning of the card receiving block of the push card device and the card inlet of the horizontal push card loading device more reasonable. This not only improves shuffling efficiency but also reduces the chance of tiles colliding on the shuffling tray, thereby reducing shuffling noise.

[0046] In this preferred embodiment, the loading housing of the horizontal push loading device is generally formed of one or more rectangular boxes. The top of the rectangular box is a card receiving plate for receiving and arranging multiple piles of mahjong tiles. The loading transmission mechanism is housed within the rectangular box. The front sidewalls of the rectangular box are provided with a crisscrossing mesh of reinforcing ribs. Guide shaft seats and guide shafts for guiding the vertical movement of the card receiving plate are provided at both ends of the front side of the grid plate. In other embodiments, the rear sidewalls of the rectangular box are provided with a crisscrossing mesh of reinforcing ribs.

[0047] This embodiment is preferred, as Figure 1 and Figure 2 As shown, the card loading shell 70 of the push-pull card loading device no longer has a front side wall on the front side near the shuffling frame. In this way, the original internal space of the card loading shell, the space below the card bearing plate, becomes an open space, so that the shuffling plate / shuffling frame and the card feeding motor can extend into the open space, and the card loading shell 70 becomes an open shell structure formed by the rear side wall, the top wall and the left and right side walls. The top wall of the loading housing 70 forms a fixed, non-elevating card receiving plate 72. Because the top wall is fixed, it is relatively thin. The shuffling frame positioned below it does not further increase the height difference between the card delivery device's card outlet and the lowest point where the card raising plate descends, nor does it increase the overall thickness of the mahjong machine. This is more reasonable than the hollowed-out bottom structure disclosed in patent documents such as CN109794059. The rear sidewall of the loading housing 70 houses the push-pushing loading motor 71 and the loading transmission mechanism. To reduce the volume occupied by the loading transmission mechanism within the open space below the card receiving plate, the rear sidewall is preferably configured to project rearward, while its front face is recessed to form several grooves for accommodating some of the components of the loading transmission mechanism. The left and right sidewalls of the loading housing 70 are fixedly connected to the loading guide shaft seat 701. To increase the overall strength of the loading housing 70 and facilitate injection molding, a bottom wall is also provided. However, this bottom wall can be hollowed out where it interferes with the shuffling plate and the feeding motor to avoid interfering with these two arrangements.

[0048] In other embodiments, a number of reinforcing ribs or concave-convex structures may be added to increase the overall strength or local strength of the rear side wall.

[0049] This embodiment is preferred, as Figure 2 As shown, some of the mesh-shaped reinforcement ribs also enclose grooves for accommodating some components in the card support plate transmission mechanism.

[0050] In order to facilitate the reliable setting of shaft parts such as gear shafts, camshafts, rocker shafts, etc. in the card loading transmission mechanism, corresponding shaft seats or shaft covers can be set. These shaft seats or shaft covers can be fixedly connected to the rear side wall, bottom wall and / or top wall of the card loading shell 70, or they can be fixedly connected to the mahjong machine bottom plate 1 or the shuffling frame card feeding shell and its connecting wall. In this way, independent shaft seats or shaft covers can be flexibly set in various positions, which is convenient for installation and adjustment.

[0051] This embodiment is preferred, as Figures 1 to 6 As shown, the card supporting plate transmission mechanism includes:

[0052] The card loading drive cam 748 is mounted on the card loading housing 70 and is driven to rotate by the horizontal push card loading motor 71; cam grooves are provided on both the front and rear surfaces of the card loading drive cam 748;

[0053] The two card loading connecting rods 747 are respectively connected to the front and rear cam grooves of the card loading driving cam 748; the card loading connecting rods 747 are provided with a first card loading connecting rod sliding sleeve 7471 and a second card loading connecting rod sliding sleeve 7472, and the card loading connecting rod sliding sleeve 7471 is fixed to the card loading housing 70, so that the card loading connecting rods 747 can move back and forth in a straight line;

[0054] The card loading rocker arm shaft 745 is rotatably mounted on the card loading housing 70 , and the two card loading rocker arms 743 are respectively fixed on the two card loading rocker arm shafts 745 ;

[0055] The card loading swing arm 746 has one end fixedly connected to the card loading rocker arm shaft 745, and the other end movably connected to the card loading connecting rod 747. The connection point between the card loading swing arm 746 and the card loading connecting rod 747 is located between the first card loading connecting rod sliding sleeve 7471 and the second card loading connecting rod sliding sleeve 7472;

[0056] The two card-loading curve cams 744 are respectively installed on the left and right sides of the bottom of the card-supporting plate 74, and the card-supporting plate 74 is connected to the card-loading shell 70 for sliding up and down; the two card-loading rocker arms 743 respectively cooperate with the two card-loading curve cams 744 for movement.

[0057] In this way, the movement direction of the card-loading link is limited by the two card-loading link sleeves, making the movement of the card-loading link smoother, and the connection point between the card-loading swing arm and the card-loading link is located between the two card-loading link sleeves, which can effectively reduce the wear between the card-loading link sleeve and the card-loading link, and effectively improve the service life of the mechanism and the reliability of the mechanical movement.

[0058] In the above structure, the card-loading curved cam 744 is smaller in size, the card-loading rocker arm 743 is installed at a higher position and swings intermittently, and the card-loading rocker arm 743 is suspended and extended forward through the card-loading rocker arm shaft 745, so that the card-loading connecting rod 747 and the card-loading driving cam 748 can be set further back. Compared with the existing technology, the card support plate transmission mechanism of this embodiment occupies less shuffling space, can increase the diameter of the shuffling plate, increase the shuffling space, not only improve the shuffling efficiency, but also reduce the probability of mahjong tiles colliding with each other on the shuffling plate, thereby achieving the effect of reducing shuffling noise.

[0059] This embodiment is preferred, as Figure 5 As shown, two card loading connecting rods 747 are provided, and cam grooves are provided on both the front and rear sides of the card loading driving cam 748, and the front and rear cam grooves respectively cooperate with the two card loading connecting rods 747. In this way, the use of double-sided cams to drive the two card loading connecting rods has better synchronization, and the card supporting plate transmission mechanism has a simple structure, a compact size, and is easy to adjust.

[0060] In this embodiment, the front end of the card loading rocker arm shaft 745 is fixedly connected to or integrally formed with the card loading rocker arm 743, and the rear end of the card loading rocker arm shaft 745 is fixedly connected to or integrally formed with the card loading swing arm 746. The card loading swing arm 746 is movably connected to one end of the card loading connecting rod 747. Preferably, a waist-shaped hole is formed on the card loading swing arm 746, and a roller is installed on the card loading connecting rod 747. The roller is plugged into the waist-shaped hole and can move within the waist-shaped hole.

[0061] In the preferred embodiment, the two card loading rocker arms 743 can rotate in the same direction, but preferably the two card loading rocker arms 743 rotate in opposite directions to support the lifting of the card supporting plate 74. A card loading rocker arm shaft 745 is sleeved with a card loading rocker arm shaft seat 7451, which is fixed to the rear side wall of the card loading housing 70. The card loading connecting rod 747 moves in coordination with the cam groove of the card loading drive cam 748 via a roller. The two card loading connecting rods 747 and the two card loading swing arms 746 / card loading rocker arm gears 7452 are arranged in a corresponding manner on the left and right sides, and the card loading drive cam 748 is arranged between them, and the cam grooves on the front and rear sides of the card loading drive cam 748 are arranged symmetrically on the left and right sides.

[0062] In this preferred embodiment, two card loading guide shafts 741 are fixed to the bottom of the card holding plate 74. The card holding plate 74 rises and falls along the card loading guide shafts 741. The card loading guide shaft seat 701, which slides and guides the card loading guide shafts 741, is fixedly connected to or integrally formed with the card loading housing 70. In other preferred embodiments, the card loading guide shafts can be fixedly connected to or integrally formed with the card loading housing 70, and the guide sleeve can be fixedly connected to or integrally formed with the card holding plate.

[0063] In this embodiment, the card loading guide shaft 741 on the inner side of the card supporting plate 74 is arranged near the card inlet end of the card receiving plate 72, and the card loading guide shaft 741 is located outside the shuffling frame. This avoids the card loading guide shaft from encroaching on the shuffling space, so that the shuffling frame and the shuffling plate can be maximized.

[0064] Push plate transmission mechanism, such as Figure 3 、 Figure 5 and Figure 6 As shown, the card pushing frame 731 includes a horizontal push slider 7311, a horizontal push cam 732, and a horizontal push pendulum 734. The horizontal push slider 7311 slides back and forth on the card pushing frame 731 along a guide rod. The card pushing plate 73 is fixed to the horizontal push slider 7311. The upper end of the horizontal push pendulum 734 is movably connected to the horizontal push slider 7311. The lower end of the horizontal push pendulum 734 is hinged to the card loading housing 70 via a horizontal push pendulum shaft 735. A horizontal push rocker arm 733 is fixed to the horizontal push pendulum shaft 735. The swing end of the horizontal push rocker arm 733 movably cooperates with the horizontal push cam 732 via a roller. The horizontal push card loading motor 71 drives the horizontal push slider 7311 to slide back and forth to push the cards. In this embodiment, there are two horizontal push pendulums 734, and the lower ends of the two horizontal push pendulums 734 are fixedly connected to the horizontal push pendulum shaft 735.

[0065] In this embodiment, the horizontal push cam 732 and the horizontal push card loading motor 71 are both arranged directly below the card pushing frame 731, and the two horizontal push swing rods 734 are respectively arranged on the left and right sides of the card pushing frame 731. In this way, the card loading transmission mechanism is centrally arranged at the central rear of the horizontal push card loading device, which has a compact structure and takes up little space.

[0066] In this embodiment, a first transmission gear 711 is preferably fixed to the output shaft of the horizontal push card loading motor 71. The horizontal push cam 732 and the card loading drive cam 748 are coaxial. A second transmission gear 749 is fixed to the same shaft. The second transmission gear 749 is located between the card loading drive cam 748 and the horizontal push cam 732. The first transmission gear 711 and the second transmission gear 749 are meshed and transmitted. In this way, the number of gear transmission stages is small, the horizontal push card loading synchronization is good, the structure is compact, and the space occupied is small.

[0067] To prevent mahjong tiles from being pushed onto the shuffling plate or getting stuck by the push plate when the tiles are pushed onto the table, a retaining frame is preferably provided on the inner side of the square support plate. The retaining frame includes a retaining portion near the inner edge of the support plate, which is used to prevent the mahjong tiles on the support plate from continuing to move inward. The retaining frame is fixed above the shuffling frame. Furthermore, the retaining frame is preferably integrally formed in a windmill shape, which is simple in structure and easy to install. The integral retaining frame has a large central hole, in which a central lifting device is installed. The retaining frame not only prevents the tiles from falling, but also effectively supports the table top.

[0068] The method for arranging mahjong tiles using the mahjong machine of this embodiment includes the following steps:

[0069] 1) Card delivery: The card delivery device picks up mahjong tiles from the shuffling plate and delivers them to the card pushing device;

[0070] 2) Stacking and pushing tiles; the tile receiving block of the tile pushing device receives a tile sent by the tile sending device at the first stop position;

[0071] The tile receiving block descends to the second stop position to receive another mahjong tile sent by the tile feeding device; the tile receiving block ascends to the third stop position and the tile pushing head pushes the two mahjong tiles stacked into one pile onto the tile receiving plate 72 of the horizontal push loading device, and then the tile receiving block and the tile pushing head are reset;

[0072] 3) Repeat step 2 above until the required number of mahjong tiles are arranged on the tile support plate 72 of the push-pushing device;

[0073] 4) Pushing the tiles horizontally; after receiving the tile loading instruction, the tile supporting plate 74 of the push-to-load device descends from the table to a low position; the pushing plate 73 pushes the multi-dung mahjong tiles on the supporting plate 72 onto the tile supporting plate 74; and the tile supporting plate 74 rises to the table.

[0074] The tabletop of a conventional flat push-on windmill mahjong machine is 81.5×81.5 cm square, and the maximum diameter of its shuffling plate and effective shuffling space can only be 520 mm, and the maximum size of the mahjong tile can only be 50. Figure 2 As shown, a mahjong machine core of the same size adopts the structure of this embodiment, and the diameter of the shuffling plate and the effective shuffling space can be up to 600 mm, and a maximum of 62-size mahjong tiles can be played.
