Push-loading device and mahjong machine

Abstract

The present invention discloses a horizontal push loading device and a mahjong machine. A support plate is formed with a support area for placing a mahjong tile wall and a transition area outside the support area where no mahjong tile wall is placed. The transition area connects to the support plate only when a push plate pushes tiles and allows the mahjong tile wall to pass through. This solution extends and widens the support plate inward, with the width of the support plate being greater than the width of the mahjong tile wall. This allows the square mahjong tile wall to be pushed inward, eliminating the need for players to push tiles inward when playing. The device has a simple and reasonable structure, high tile sorting efficiency, fast loading speed, and reliable and stable operation.

Description

Technical Field

[0001] The invention belongs to the field of mahjong machine manufacturing, and in particular relates to a horizontal push card loading device and a mahjong machine. Background Art

[0002] Mahjong is a popular recreational tool and is even considered a competitive sport. However, traditional mahjong machines place the square tiles parallel to the table's edges when raised. Furthermore, the tiles are placed very close to the edge, creating an awkward placement. Players must manually maneuver the tiles forward and diagonally into the appropriate position before drawing a tile. This process can cause tiles to fall over, creating inconvenience for players.

[0003] Patent documents such as publication number CN200966910 disclose a mahjong machine with a ramped tile loading system. The machine comprises a tabletop with a center tile loading opening. Four rectangular, windmill-shaped tile outlets are arranged on the tabletop and tilted at an angle to the edges of the tabletop. Below the tabletop are four curved tile storage slots, also arranged in a windmill pattern. Each tile storage slot is equipped with a pusher at the end. Each tile outlet is equipped with a lift plate, one end of which is hinged to the tile outlet and the other end is movably connected to a lift mechanism. The four tile outlets are arranged in a windmill pattern. When loading tiles, a portion of the tiles are first placed on the tabletop along the lift plate, leaving the remaining tiles on the lift plate. Finally, the lift mechanism lifts the tiles on the lift plate onto the tabletop. Although this roller coaster-style mahjong machine can tilt the mahjong tiles in a windmill shape after the tiles reach the table, the loading speed is slow, and the tiles loaded along the slope are prone to gaps, confusion, or even overturning after they rise to the table. Generally, players still need to manually organize the tiles, and the inconvenience caused to players has not been completely solved.

[0004] Patent documents such as publication number CN109381855A disclose a mahjong machine in which the mahjong tiles on each of the four sides of the mahjong table are lifted onto the tabletop at once, tilted toward the four edges of the tabletop and positioned near the center of the tabletop. However, the layout of the conveying mechanism, stacking and pushing mechanism, and loading mechanism on each side of the mahjong machine is not rational, resulting in only one lifting plate bracket being provided at the bottom of each lifting plate. To ensure the lifting plates can be raised and lowered, each pair of adjacent lifting plates of the loading mechanism is connected by a fixing plate, and the four lifting plates on each side must be raised and lowered synchronously. Because the four lifting plates are connected as a single unit and are bulky, and are driven by four loading motors separately, the lifting plates cannot be raised and lowered synchronously. As a result, the loading mechanism has poor operational stability and is prone to jamming and damage. And also due to the layout restrictions, the height difference between the card outlet height of the conveying mechanism and the descending height of the card lifting plate is large, and the lifting span of the card receiving seat in the stacking and pushing mechanism is too large (greater than the thickness of two mahjong tiles). The stacking and pushing efficiency is low, the operation is unstable, and the mahjong cards are easily confused.

[0005] Patent documents such as publication number CN112023390A disclose a mahjong machine, including a shuffling plate located in the center of the bottom plate of the frame, four groups of card picking and transporting systems are arranged around the shuffling plate, the card picking and transporting system includes a card feeding device, a horizontal push card loading device and a card pushing device; the horizontal push card loading device includes a card receiving plate, a card supporting plate and a card pushing plate, the card supporting plate is located on the inner side of the card receiving plate, the card pushing plate is located on the outer side of the card receiving plate and pushes the cards from the outside to the inside, one end of the card receiving plate extending along the length direction is a card inlet, a card receiving block of the card pushing device is arranged outside the card inlet, and a horizontal push card loading motor drives the card pushing plate to translate and push the cards and the card supporting plate to lift and lower the cards; four card loading ports are provided on the mahjong machine panel, respectively inclined relative to the side edges of the table top, and the four card supporting plates in the four groups of card picking and transporting systems respectively cooperate with the four card loading ports. This solution adopts four-way independent horizontal push card loading and makes full use of the space at the corner connection of the two card feeding devices to set up the card loading support frame and its card loading crank, so that the lifting and lowering of the card supporting plates of the four-way horizontal push card loading devices are driven by their own motors to load cards independently.

[0006] However, in the flat-push-loading windmill-shaped mahjong machines disclosed in the patent documents CN109381855A and CN112023390A, the square tile wall arranged in a windmill shape is positioned further outward than the square tile wall of the sloped windmill-shaped mahjong machine. Generally, the player still needs to manually push the tile wall inward a little to facilitate playing, which still causes inconvenience to the player. Moreover, in this type of mahjong machine structure, the card-discharging direction of the card-feeding device and the card-feeding direction of the flat-push-loading device are not perpendicular, but are at an acute angle. The mahjong tiles discharged from the card-feeding device need to be rotated a certain angle before they can be pushed into the card storage slot (on the card receiving plate) of the flat-push-loading device. The card-pushing head in the card-pushing device moves linearly along the card-feeding direction (the length direction of the card receiving plate) of the flat-push-loading device to push the tiles. This can easily lead to poor card pushing or card jamming. Summary of the Invention

The card receiving block 61 and the card pushing head 62 are driven by a card pushing motor 68. The specific structure of the card pushing device can adopt the existing technology, and reference can be made to patent documents such as publication numbers CN201906453U, CN201949619U, CN103861280A, CN112023390A, and CN204699375U. However, the card pushing heads of the card pushing devices in the prior art all push cards in a straight line, while in the windmill-shaped mahjong machine structure of the horizontal push card loading type, the card discharging direction of the card feeding device and the card feeding direction of the horizontal push card loading device are not perpendicular, but are at an acute angle. The mahjong tiles coming out of the card feeding device need to be rotated at a certain angle before they can be pushed into the card storage slot (on the card receiving plate) of the horizontal push card loading device. In this way, the card pushing head in the card pushing device moves in a straight line along the card feeding direction (the length direction of the card receiving plate) of the horizontal push card loading device to push cards, which can easily lead to poor card pushing or card jamming.

[0085] Therefore, in this embodiment, it is preferred that the card pushing device adopts a swinging card pushing head. Figure 5 and Figure 6 The illustrated card pushing device includes a card pushing housing, a card pushing motor 68 mounted on the housing, a card pushing transmission mechanism disposed within the housing, and a card receiving block 61 and a card pushing head 62 disposed on the exterior of the housing. The card pushing motor 68 drives the card receiving block 61 up and down via the card pushing transmission mechanism to stack the mahjong tiles. The card pushing motor 68 drives the card pushing head 62 via the card pushing transmission mechanism to swing back and forth horizontally about a specific axis, thereby pushing the stacked mahjong tiles from the card receiving block 61. The specific axis is vertically disposed outside the card receiving block 61 and along the card-discharging direction of the card feeding device 5. Thus, the use of a swinging card pushing head is more suitable for the layout of the card feeding device and the flat-push card loading device of a windmill-shaped mahjong machine, and card pushing is smooth and stable without card jamming.

[0086] Further preferably, the pusher head 62 has at least two pusher positions: when the pusher head 62 begins to push the mahjong tile on the tile support block 61, the first pusher position first contacts the mahjong tile; when the pusher head 62 pushes the mahjong tile onto the tile support plate 72, the second pusher position contacts the mahjong tile, or the first and second pusher positions contact the mahjong tile simultaneously. The pusher positions herein can be pusher positions that form surface contact or line contact with the upper and lower mahjong tiles. In this embodiment, the first pusher position is preferably a pusher position that forms line contact with the upper and lower mahjong tiles. For example, the pusher surface of the pusher head 62 includes a first plane and a second plane, and the two planes are at different distances from the specific axis: when the pusher head 62 begins to push the mahjong tile on the tile support block 61, the junction of the two planes or the first plane first contacts the mahjong tile; when the pusher head 62 pushes the mahjong tile onto the tile support plate 72, the second plane contacts the mahjong tile. In this way, not only can the mahjong tiles be turned first so that the mahjong tiles can be pushed into the tile storage slot (formed by the tile support plate and its inner and outer side retaining walls) of the horizontal push loading device more smoothly, but also the tile pushing head can be prevented from directly contacting and colliding with the mahjong tiles to generate loud noise, and the noise or jamming caused by the collision of the mahjong tiles with the retaining walls at the entrance of the tile storage slot can be avoided. At the same time, the swing range of the tile pushing head can be reduced to avoid interference with the mahjong tiles on the tile support block.

[0087] In a further preferred embodiment, the card pushing transmission mechanism includes a card pushing curve wheel 69, a lifting slider 611, a swing arm 613, and a card pushing swing arm 620. A card pushing motor 68 drives the card pushing curve wheel 69 to rotate. One end of the swing arm 613 is movably connected to the lifting slider 611. A card receiving block 61 outside the card pushing housing is fixedly connected to the lifting slider 611 inside the card pushing housing via a card receiving block extension arm 610. The other end of the swing arm 613 is hinged to the card pushing housing. The swing arm 613 is driven by the card pushing curve wheel 69 to swing up and down, thereby driving the lifting slider 611 and the card receiving block 61 up and down. A card pushing head 62 outside the card pushing housing is fixed to one end of the card pushing swing arm 620, the other end of which is hinged to the card pushing housing. The card pushing swing arm 620 is driven by the card pushing curve wheel 69 to swing horizontally, thereby driving the card pushing head 62 to swing back and forth horizontally about a specific axis. Thus, compared to the prior art, the translation slider assembly is omitted, resulting in fewer parts, cost savings, easier assembly, and more reliable operation.

[0088] In the preferred embodiment, the card pushing swing arm 620 is located above the card pushing housing and is movably connected to the card pushing curve wheel 69 in the card pushing housing through an active connector that passes through an opening in the card pushing housing. In this way, the card pushing housing is smaller in size, more rational in structure, more convenient to install, and less expensive. In the present embodiment, the active connector is a guide wheel mounted on the card pushing swing arm 620, and a curved groove that movably cooperates with the guide wheel is provided on the circumference of the card pushing curve wheel 69. In other embodiments, the active connector can also be a slider that is slidably arranged on the card pushing housing, the upper end of the slider movably cooperates with the card pushing swing arm 620, and the lower end of the slider movably cooperates with the card pushing curve wheel 69.

[0089] In this embodiment, the card pushing housing includes a first card pushing housing 64 and a second card pushing housing 65, which are fixedly connected in a relative manner. A card pushing curve wheel 69 is installed between the first card pushing housing 64 and the second card pushing housing 65. A card pushing motor 68 is installed on the first card pushing housing 64, and a bracket 67 is fixed on the second card pushing housing 65.

The bracket 67 and the first card pushing housing 64 are respectively located on the front and rear sides of the card receiving block 61. The card pushing head 62 swings back and forth around a specific axis to push cards. A transition platform 641 is provided on the top of the first card pushing housing 64 to transition with the card receiving plate 72 in the flat push card loading device 7. In this way, the card pushing device has a more reasonable structure and is more convenient to assemble.

[0090] In this embodiment, a roller is installed in the middle of the rocker arm 613, and a curved groove that cooperates with the roller is provided on the end face of the card pushing curve wheel 69. A lifting slider guide 612 is provided inside the card pushing shell, and the lifting slider 611 is lifted up and down along the lifting slider guide 612; the lifting slider 611 and the lifting slider guide 612 are arranged inside the card pushing shell. In other embodiments, the lifting slider 611 can also be arranged outside the card pushing shell and connected to the card pushing curve wheel 69 through the rocker arm 613.

[0091] In this embodiment, a counting device is mounted on the pusher housing to detect the number of times a tile is pushed. A card delivery detection device 66 is located near the card receiving block 61 to detect whether a tile has been delivered from the card delivery device's outlet to the card receiving block 61. In this embodiment, the card delivery detection device 66 is preferably mounted on a bracket 67. Both the counting device and the card delivery detection device are preferably photocells.

[0092] The card pushing process of the card pushing device 6 in this embodiment is as follows:

[0093] The initial position is Figure 7 、 Figure 8 and Figure 9As shown, the card pushing head 62 is located on the side close to the card holding plate 72 to avoid interference of the card pushing head 62 with the lifting of the card supporting plate 71; Figure 10 As shown, the tile receiving block 61 receives the first tile at the first position, and then descends to the second position to receive the second tile. The tile pushing head 62 moves to the side away from the tile receiving plate 72, as shown in FIG. Figure 11 、 Figure 12 、 Figure 13 and Figure 14 As shown; then, as Figure 15 and Figure 16 As shown, the card block 61 rises to the height of the card plate 72; Figure 17 、 Figure 18 、 Figure 19 、 Figure 20 and Figure 21 , and then the pusher 62 pushes a pile of mahjong tiles 100 onto the card receiving plate 72 via the transition platform 641, and the card receiving block 61 descends and resets to prepare to take the next mahjong tile; finally, as Figure 22 and Figure 23 As shown, the tile pusher 62 is reset and waits for pushing the next mahjong tile.

[0094] In other embodiments, the card holding block 61 may also not be raised or lowered, that is, the card pushing device 6 does not have the card stacking function, but only has the card pushing function, and the card pushing motor 68 only drives the card pushing head 62 to push cards horizontally or to swing back and forth horizontally around a specific axis through the card pushing curve wheel 69.

[0095] The horizontal pushing card loading device 7 includes a card receiving plate 72 for receiving and arranging multiple piles of mahjong tiles, a card supporting plate 71 for delivering multiple piles of mahjong tiles to the table at one time, and a card pushing plate 73 for pushing multiple piles of mahjong tiles on the card receiving plate 72 to the card supporting plate 71. The card receiving plate 72 is arranged on the card loading seat 70, the card supporting plate 71 is located on the inner side of the card receiving plate 72, the card pushing plate 73 is located on the outer side of the card receiving plate 72 and pushes the cards from the outside to the inside, and one end of the card receiving plate 72 extending along the length direction is a card inlet, and a card receiving block 61 of the card pushing device 6 is arranged outside the card inlet. A card loading transmission mechanism is provided in the card loading seat 70, and a horizontal pushing card loading motor 76 drives the card pushing plate 73 to push cards and the card supporting plate 71 to rise and fall to load cards through the card loading transmission mechanism.

[0096] In this embodiment, Figures 1 to 4As shown, the mahjong tabletop 4 is provided with four card loading openings 41 and a central card placement opening 42. Four card support plates 71 in the four sets of card picking and transporting systems respectively cooperate with the four card loading openings 41. When the card support plates 71 are raised, they fill the card loading openings 41 and are flush with the tabletop 4. The card support plates 71 are located above the card delivery frame, and the card receiving plates 72 are located outside the card delivery frame. In the same group of card picking and transporting system, the card holding block 61 of the card pushing device 6 is located at the junction of the card feeding device 5 and the horizontal pushing card loading device 7, and the card pushing head 62 of the card pushing device 6 is located above the card holding block 61 and swings back and forth horizontally around a specific axis to push cards. The specific axis is arranged along the card-discharging direction of the card feeding device 5 and is located on the outside of the card holding block 61. The angle A between the card-discharging direction of the card feeding device 5 and the card-feeding direction of the horizontal pushing card loading device 7 is 65°~85° (further preferably 70°~79°), the angle C between the card pushing direction of the card pushing plate 73 of the horizontal pushing card loading device 7 and the side edge of the desktop panel 4 on its adjacent side is 65°~80° (preferably 77°), and the angle D between the card-discharging direction of the card feeding device 5 and the side edge of the desktop panel 4 on its adjacent side is 0°~5° (preferably 0°). In this way, the card supporting plate 71 of the horizontal push card loading device 7 in the card picking and transporting system of one party is located above the card feeding device 5 in the card picking and transporting system of the adjacent party, and compared with the horizontal push card loading windmill-shaped mahjong machines disclosed in patent documents such as CN209645828U, CN109381855A and CN112023390A, the angle between the card feeding device 5 and the horizontal push card loading device 7 is larger, and the layout is more compact and reasonable. For mahjong machines of the same size, the shuffling plate and the card feeding frame can be made larger, so that larger-sized mahjong machines can be played.

[0097] In this embodiment, the card loading transmission mechanism includes a lifting drive mechanism of the card supporting plate 71 and a horizontal pushing drive mechanism of the card pushing plate 73.

[0098] The lifting drive mechanism of the card support plate 71 can adopt the structures disclosed in patent documents such as CN209645828U, CN213527413U, CN109381855A and CN112023390A. Generally speaking, the lifting drive mechanism of the card support plate 71 includes a card loading cam 713 and a card loading crank 714. The bottom of the card support plate 71 is connected to the card loading seat 70 for vertical sliding via two guide rods.

The horizontal card loading motor 76 drives the two card loading cranks 714 to rotate and cooperate with the two card loading cams 713 to drive the card support plate 71 up and down.

[0099] In the prior art, the bottom position of the loading cam 713 is low, the loading crank 714 is installed at a low position, and the loading crank 714 rotates cyclically, which causes the push loading device to occupy too much shuffling space, resulting in reduced shuffling efficiency and loud shuffling noise.

The bottom of the card receiving plate 72 is connected to the card loading seat 70 for vertical sliding movement via a card raising guide shaft and a card raising guide shaft seat. Two card raising support frames are provided on both sides of the bottom of the card receiving plate 72. The bottom of the card raising support frames is provided with a card raising cam curve. The horizontal push card loading motor 76 pushes the card raising support frames via the card raising crank, thereby driving the card receiving plate 72 to rise and fall. In this embodiment, the card receiving plate 72 has at least two stop positions: in the first stop position, which is low, the card receiving plate 72 receives two mahjong tiles stacked in one pile pushed by the card pushing device 6; in the second stop position, which is high, the card pushing plate 73 pushes the multiple piles of mahjong tiles arranged on the card receiving plate 72 onto the card supporting plate 71. In this way, the card receiving plate 72 descends to a low position to receive the mahjong tiles pushed from the card pushing device 6. When the tiles are pushed horizontally, the card receiving plate 72 rises to a high position to push the tiles onto the card supporting plate 71. This greatly reduces the lifting span of the card receiving block 61 in the card pushing device 6 (approximately the thickness of a mahjong tile), thereby improving the efficiency and stability of stacking and pushing the tiles. Preferably, the inner side of the card receiving plate 72 is provided with an inner retaining wall, and the outer side of the card receiving plate 72 is provided with an outer retaining wall. The inner and outer retaining walls are integrally formed or fixedly connected to the card loading seat 70. When the card receiving plate 72 rises upward, its height is higher than the inner retaining wall, thereby preventing the mahjong tiles on the card receiving plate 72 from falling into disorder. In this embodiment, the card loading transmission mechanism uses a horizontal push card loading motor 76 to drive the card supporting plate 71, the card receiving plate 72, and the card pushing plate 73 to achieve card lifting, pushing, and loading.

[0121] In other embodiments, the horizontal pushing device 7 having the above-mentioned lifting and lowering card-receiving plate 72 can also be combined with the card pushing device 6 for pushing a single mahjong tile, so that the card-receiving plate 72 has at least three stop positions: in the first stop position, the card-receiving plate 72 receives the single mahjong tile pushed by the card pushing device 6 and arranges it to form a first layer of mahjong tiles; in the second stop position, the card-receiving plate 72 receives the single mahjong tile pushed by the card pushing device 6 and arranges it to form a second layer of mahjong tiles; in the third stop position, the card pushing plate 73 pushes the multiple piles of mahjong tiles arranged on the card-receiving plate 72 onto the card supporting plate 71.

[0122] In other embodiments, the flat-push card loading device 7 having the above-mentioned liftable card supporting plate 72 can also adopt staged card loading. For example, three layers of mahjong tiles are stored on the card supporting plate 72. When loading the tiles, the card supporting plate 71 drops to the bottom, and the card pushing plate 73 first pushes the top layer of mahjong tiles onto the card supporting plate 71. The card supporting plate 71 rises upward to send the mahjong tiles to the table. After the player takes the mahjong tiles away, the card supporting plate 71 drops again, and the card pushing plate 73 pushes the remaining two layers of mahjong tiles onto the card supporting plate 71. The card supporting plate 71 rises upward to send the mahjong tiles to the table.

[0123] In the prior art, the flat-push-loading windmill-shaped mahjong machines disclosed in patent documents such as CN209645828U, CN109381855A, and CN112023390A have a square tile wall arranged in a windmill shape that is further outward than the square tile wall of a sloped-loading windmill-shaped mahjong machine. Generally, players still need to manually push the tile wall inward to make it suitable for playing, which still causes inconvenience to players. Therefore, it is preferable to push the tile wall inward to a position similar to the position of the tile wall of a sloped-loading windmill-shaped mahjong machine, so that players do not need to push the tiles.

[0124] One embodiment is to use a conventional structure for the card support plate 71 and its driving mechanism, wherein the card support plate 71 extends inward and widens, and the width of the card support plate 71 is greater than the width of the mahjong tile wall. That is, the card support plate 71 forms a supporting area for placing the mahjong tile wall and a transition area outside the supporting area where the mahjong tile wall is not placed. The transition area is connected to the card support plate 72 only when the card pushing plate 73 pushes the cards and allows the mahjong tile wall to pass through. However, this structure has several problems: first, the wide card loading opening and card support plate on the table top affect the aesthetics of the mahjong machine; second, the four wide card loading openings result in a large hollow area on the table top, low strength, and easy deformation; and third, to prevent the lifting assembly (including the guide rod, card loading crank, and card loading cam, etc.) at the bottom of the card support plate 71 from excessively encroaching on the shuffling space, the lifting assembly generally supports the card support plate 71 outside the mahjong tile wall. This results in an unbalanced and unstable support for the card support plate, which can easily cause the card support plate to loosen, shortening the service life of the mahjong machine. Of course, the latter two problems can be solved by improving materials, adding reinforcements or strengthening structures. Therefore, this embodiment can be used in situations where the aesthetic requirements for the mahjong machine are not high.

[0125] Another embodiment is to maintain the width of the card support plate 71 and move it inward. When the card support plate 71 reaches the bottom, a transition plate 74 is provided between the card support plate 71 and the card receiving plate 72. This connects the card receiving plate 72 and the card support plate 71 when the card pushing plate 73 pushes the cards, allowing the mahjong tile wall to pass through. The transition plate 74 is mounted on the card support plate 71, the card receiving plate 72, or the upper card holder 70. The transition plate 74 can be fixed or integrally formed on the card receiving plate 72 or the upper card holder 70.

[0126] This embodiment is preferred, as Figure 24 、 Figure 25 、 Figure 34 、 Figure 37 、 Figure 40 、 Figure 43 、 Figure 47 and Figure 48 As shown, the transition plate 74 is hinged to the inner side of the card support plate 72 or the card holder 70 so that the transition plate 74 can be erected or laid flat. Figure 25As shown, the transition plate 74 is in an upright state so as to serve as an inner retaining wall of the card support plate 72 to prevent the mahjong tiles from falling from the card support plate 72; when the card loading device 7 is pushed, as shown in FIG. Figure 26 and Figure 27 As shown, the card supporting plate 71 is lowered, the transition plate 74 is laid flat, and the card pushing plate 73 pushes the mahjong tile wall inward; Figure 28 and Figure 29 As shown, the transition plate 74 is in a flat state to form a transition area through which the mahjong tile wall can be pushed; Figure 30 and Figure 31 As shown, the pushing plate 73 pushes the mahjong tile wall onto the supporting plate 71 and then resets, and the transition plate 74 stands up and resets; Figure 32 and Figure 33 As shown, the supporting plate 71 raises the mahjong tile wall onto the mahjong table. The structure is simple, the installation is convenient, and the function is reliable.

[0127] Furthermore, preferably, the transition plate 74 is provided with an elastic member that imparts an upward tendency to the transition plate 74. This allows the transition plate to remain upright when not subject to external forces and to be pressed flat by the card pusher. This not only prevents interference between the transition plate 74 and the card support plate 71, but also eliminates the need for additional support members. The elastic member can be a tension spring, a torsion spring, or an elastic push rod, but is preferably a torsion spring mounted on the hinge axis of the transition plate 74.

[0128] In this embodiment, the transition plate 74 preferably has an elastic member that imparts a tendency to lie flat. This allows the transition plate to lie flat when not under external force, reducing the load on the motor pushing the cards and the noise of the card pushing collision. However, this requires additional support structures or members to support the transition plate. The elastic member can be a tension spring, a torsion spring, or an elastic push rod, but is preferably a torsion spring mounted on the hinge axis of the transition plate 74.

[0129] It is further preferred that a first transition support 711 is provided on the outside of the card support plate 71. The first transition support 711 is horizontally arranged and lower than the top surface of the card support plate 71, thereby forming a step with the card support plate 71. When the card support plate 71 is lowered to the bottom transition plate 74 and laid flat, the first transition support 711 supports the transition plate 74. When the card support plate 71 is raised to the top, the first transition support 711 can form a support with the table top plate 4. In this way, the first transition support 711 can not only support the transition plate 74, but also form a support with the bottom of the table top plate 4, thereby improving the stability of the card support plate and avoiding loosening that affects the service life. The structure is simple, reliable, and low in cost. The first transition support 711 can be a whole plate, or it can be composed of multiple small support plates. It can be an independent component fixedly connected to the card support plate 71, or it can be integrally formed with the card support plate 71. In this embodiment, it is preferred that the first transition support 711 is a whole plate integrally formed with the card support plate 71, and the support is more firm and reliable. More preferably, the lifting guide component (guide rod or guide sleeve) of the card supporting plate 71 is set on the first transition support 711, and the card loading cam 713 of the card supporting plate 71 is set at the bottom of the card supporting plate 71. This can more evenly and stably support the card supporting plate 71 and the mahjong tile wall thereon, further prevent the card supporting plate 71 from loosening and increase its service life.

[0130] Further preferably, a second transition support 712 is provided on the outside of the first transition support 711. The second transition support 712 is vertically arranged and fixedly connected to or integrally formed with the first transition support 711. When the transition plate 74 is erected and the card support plate 71 is raised, the second transition support 712 forms an inward limit for the transition plate 74. This not only provides a reliable limit for the transition plate 74, but also prevents the transition plate 74 from turning inward and interfering with the raising and lowering of the card support plate 71. The first transition support 711 can be a single plate, but is preferably composed of at least two small support plates.

[0131] In other embodiments, the transition plate 74 may also be movably disposed at the bottom of the card supporting plate 71 .

[0132] In other embodiments, Figure 47 and Figure 48 As shown, on the push-pull card loading device 7 in which the card holding plate 72 can be raised and lowered, the transition plate 74 can also be movably set on the top of the inner retaining wall of the card holding plate 72, and the inner retaining wall is integrally formed with or fixedly connected to the card loading seat 70.

[0133] The mahjong tile arrangement method using the mahjong machine and the tile picking and transporting system of this embodiment includes the following steps:

[0134] 1) Sending cards; the card sending device 5 picks up the mahjong tiles 100 from the shuffling plate 2 and sends it to the card pushing device 6;

[0135] 2) stacking and pushing tiles; the tile receiving block 61 of the tile pushing device 6 receives a tile sent by the tile feeding device 5 at the first stop position; the tile receiving block 61 descends to the second stop position to receive another tile sent by the tile feeding device 5; the tile receiving block 61 rises to the third position and the tile pushing head 62 pushes the two tiles stacked into one pile onto the tile receiving plate 72 of the flat push loading device 7, and then the tile receiving block 61 and the tile pushing head 62 are reset;

[0136] 3) Repeat step 2) above until the required number of mahjong tiles (a mahjong tile wall) is arranged on the tile support plate 72 of the horizontal push-on device 7;

[0137] 4) Push the cards horizontally; after receiving the card loading instruction, the card supporting plate 71 of the card pushing device 7 drops from the table to a low position, and the card pushing plate 73 pushes the multiple mahjong tiles (mahjong tile wall) on the card supporting plate 72 via the transition plate 74 to the card supporting plate 71; the card supporting plate 71 rises to the table.

[0138] In a preferred embodiment, in the above step 2), the first and third stop positions of the card-pushing device 6's card-supporting block 61 are at the same height. In other embodiments, the first stop position of the card-pushing device 6's card-supporting block 61 is lower than the third stop position.
