Description

Technical Field

[0001] The invention belongs to the technical field of mahjong machines, and in particular relates to a mahjong machine card loading system. Background Art

[0002] In traditional mahjong machines, mahjong tiles are typically raised from a shuffling bucket to the machine's panel using a vertical lift mechanism. Specifically, stacked mahjong tiles are first arranged on a storage board and then pushed horizontally onto a lift board. The lift board then rises vertically to be flush with the tabletop, thereby vertically transporting the tiles to the machine's panel. For example, Chinese invention patent application publication number CN111023388A discloses a mahjong machine, a horizontal push loading device, and a receiving plate lifting mechanism. The horizontal push loading device includes a receiving plate for receiving and arranging multiple mahjong tiles, a lift board for delivering multiple mahjong tiles onto the tabletop at once, and a push board for pushing multiple mahjong tiles from the receiving plate onto the lift board. The lift board is located on the inside of the receiving plate, while the push board is located on the outside of the receiving plate and pushes the tiles from the outside inward.

[0003] The disadvantages of this mahjong machine are that: mahjong tiles are pushed from the card storage board to the card raising board by a card pushing board. Since there are no mahjong tile protection measures around the card raising board, it is easy for mahjong tiles to fall off or the mahjong tile queue to be distorted when pushing tiles, resulting in card loading failure; both the mahjong machine panel and the card raising board are covered with flocked tablecloths. In order to facilitate the card raising board to return to the table, the flocked tablecloths on the card raising board cannot completely cover the card raising board, resulting in a gap between the card raising board and the flocked tablecloths on the mahjong machine panel, making the mahjong machine panel uneven, which not only affects the playing of cards, but also affects the aesthetics of the table top.

[0004] In order to solve the above problems, mahjong machines with sloped or roller coaster-style tile raising have appeared in the prior art. That is, when loading tiles, one end of the tile raising plate descends (the other end rises or remains in the same position, which is mainly determined by the position of the hinge point between the tile raising plate and the frame) until it is connected to the tile outlet of the tile storage channel. The mahjong tiles in the tile storage channel are then pushed onto the tile raising plate. After the pushing is completed, the tile raising plate and the tiles are flipped over to be flush with the mahjong machine panel, thereby transporting the tiles obliquely to the mahjong machine panel.

[0005] For example, the Chinese invention patent application with publication number CN109248436A discloses a roller coaster-style eight-mouth fully automatic mahjong machine, which includes a frame, a large plate arranged in the frame, each side of the large plate is provided with two exits, and a first card-raising and card-holding plate and a second card-raising and card-holding plate are respectively installed at the two exits; each side of the large plate is provided with a first card-feeding channel and a second card-feeding channel, the first card-raising and card-holding plate is located at the card-feeding end of the first card-feeding channel, and the second card-raising and card-holding plate is located at the card-feeding end of the second card-feeding channel; the first card-raising and card-holding plate has a card-raising position that is flipped relative to the exit and connected to the card-feeding end of the first card-feeding channel, and a card-holding position that is flipped to be flush with the exit; the second card-raising and card-holding plate has a card-raising position that is flipped relative to the exit and connected to the card-feeding end of the second card-feeding channel, and a card-holding position that is flipped to be flush with the exit.

[0006] The disadvantage of the existing sloped tile-raising mahjong machine is that the tile-raising position is on the width side of the tile-raising board, and the tile-pushing mechanism pushes a row of mahjong tiles onto the tile-raising board one by one, which requires a long tile storage channel. This not only leads to a long tile-loading time and low tile-loading efficiency, but also increases the size of the mahjong machine. Summary of the Invention

[0007] The invention aims to provide a mahjong machine card loading system, which has fast card loading and high efficiency.

[0008] In order to achieve the above-mentioned object of the invention, the technical solution of the present invention is as follows:

[0009] A mahjong machine loading system includes a frame, wherein the frame is provided with a stacking device and a card pushing device, wherein the stacking device is used to stack the tiles and push the stacked tiles one by one onto a storage board, and the card pushing device is used to deliver the mahjong tiles on the storage board to the mahjong machine panel; the card pushing device includes a card raising plate arranged parallel to the storage board, the card raising plate being tilted and arranged at a card raising opening on the mahjong machine panel, and the tilting center axis of the card raising plate extending along the length direction of the card raising plate;

[0010] The tile raising plate comprises a tile raising position which is turned over relative to the mahjong machine panel to receive the mahjong tiles from the tile storage plate, and a tile receiving position which is kept flush with the mahjong machine panel.

[0011] In the present invention, the tile raising plate can be flipped relative to the mahjong machine panel to realize sloped tile discharging, but its flipping center line extends along the length direction of the tile raising plate, so the mahjong tiles from the tile storage plate are received from the length direction side; because the tiles are raised at an angle from the length direction side, the mahjong tiles on the tile storage plate can be pushed onto the tile raising plate in one step, which greatly shortens the tile loading distance, saves tile loading time, and improves tile loading efficiency.

[0012] At the same time, since the mahjong tiles do not need to be pushed for a long distance, the volume of the mahjong machine can be greatly reduced without changing other internal structures of the mahjong machine, the volume of the tile shuffling barrel can be increased without changing the volume of the mahjong machine, and a larger tile lifting plate can be arranged without changing the volume of the mahjong machine and the tile shuffling barrel, so that more mahjong tiles can be received and more game modes can be provided for players.

[0013] Preferably, in the mahjong tile feeding system, the tile lifting plate has a first length direction side away from the tile storage plate and a second length direction side close to the tile storage plate, and the first length direction side is hinged to the mahjong machine panel.

[0014] The mahjong machine is provided with a tile feeding driving mechanism for driving the second length direction side to flip around the first length direction side, and the tile feeding driving mechanism is also used for pushing the mahjong tiles on the tile storage plate from the second length direction side to the tile lifting plate.

[0015] Hinging the first length direction side of the tile lifting plate to the mahjong machine panel makes the flipping center axis of the tile lifting plate be located at the first length direction side, so that the second length direction side has a larger flipping range, and the structure of the tile lifting plate is more compact. In particular, the first length direction side of the tile lifting plate will not be raised above the mahjong table, and will not be pressed against the mahjong machine panel when falling back, so that the velvet tablecloth on the tile lifting plate can be laid in the same area as the tile lifting plate, and there is no gap between the tile lifting plate and the mahjong machine panel, so that the mahjong table is more flat, which not only does not affect the game, but also greatly improves the aesthetic degree of the table.

[0016] In the application, the tile feeding driving mechanism can not only drive the tile lifting plate to descend or tilt up, but also push the mahjong tiles on the tile storage plate to the tile lifting plate when the tile lifting plate descends, which greatly saves the power cost required for tile feeding, reduces the number of control nodes in the mahjong machine, and reduces the failure rate of the mahjong machine.

[0017] The second length direction side of the tile lifting plate is arranged on the tile storage plate after descending, and the angle between the tile lifting plate and the tile storage plate has a great influence on whether the mahjong tiles can be smoothly transferred from the tile storage plate to the tile lifting plate. Generally, the closer the angle between the tile lifting plate and the tile storage plate is to 180°, the more smoothly the mahjong tiles are transferred.

[0018] Therefore, preferably, in the mahjong tile feeding system, the tile storage plate comprises a tile storage platform for storing mahjong tiles, the tile storage platform is arranged to be inclined upward from a side away from the tile lifting plate to a side close to the tile lifting plate, and the side away from the tile lifting plate is provided with a tile storage guardrail for preventing the mahjong tiles from sliding off the tile storage platform.

[0019] The card storage board is mounted on the card pushing seat, and the card raising board in the card raising position is set on the card storage platform. The card loading drive mechanism is used to drive the card storage board to move along the card pushing seat toward the card raising board to push the mahjong tiles onto the card raising board;

[0020] The card stacking device includes a card stacking mechanism, which includes a card stacking seat arranged at the card feeding end of the card storage plate, a card stacking platform which is on the same plane as the card storage platform, and a card stacking guardrail which is on the same plane as the card storage guardrail, and the card stacking platform and the card stacking guardrail enclose a card stacking space; the card stacking guardrail has a card stacking position which is located on the side of the card stacking platform to assist in stacking cards, and a retracting position which moves synchronously with the card storage plate to compress the card stacking space so as to retract into the periphery of the mahjong machine.

[0021] The tile storage platform is tilted upward from the side away from the lifting board to the side closer to the lifting board. When the lifting board descends, the angle between the lifting board and the storage board is closer to 180°, which helps reduce the lifting board's impact on the translation of mahjong tiles. Because the storage platform is tilted, it is necessary to install a storage guardrail on the side of the storage platform away from the lifting board.

[0022] In the present invention, the transfer of mahjong tiles from the storage board to the ascending board can be accomplished by: a loading drive mechanism drives the storage board toward the ascending board to push the tiles onto the ascending board; or, the storage board remains in position, and the loading drive mechanism directly pushes the tiles on the storage board toward the ascending board. The first method is preferred in the present invention because, when the storage board remains in position, the area of ​​the mahjong machine remains unchanged; whereas, when the storage board can be repositioned, the area of ​​the mahjong machine can be reduced. When the mahjong machine needs to be packaged and transported, it can be packaged in smaller packages, thereby saving transportation costs and space. Furthermore, the ascending board can be positioned closer to the center of the shuffling bucket, making it easier for players to grab tiles.

[0023] In order to ensure that mahjong tiles can smoothly move from the stacking seat to the storage board, the stacking seat and the storage board are on the same plane; and in order to retract the outer periphery of the mahjong machine as a whole, the stacking space of the present invention is configured to be deformable, and the stacking guardrail can move synchronously with the storage board.

[0024] In the above-mentioned mahjong machine card loading system, the card loading drive mechanism includes:

[0025] Branded motor;

[0026] a transmission cam linked to the output shaft of the card-loading motor;

[0027] A card pushing transmission assembly is provided between the transmission cam and the card storage plate, and the card storage plate is driven by the card pushing transmission assembly to move closer to or away from the card raising plate;

[0028] A card-lifting transmission component is arranged between the transmission cam and the card-lifting plate, and the card-lifting plate is turned over relative to the mahjong machine panel under the drive of the card-lifting transmission component.

[0029] The card loading drive mechanism of the present invention is only provided with one card loading motor, and adopts a transmission cam linked with the card loading motor to respectively drive the card pushing transmission assembly and the card raising transmission assembly, thereby driving the card raising plate and the card storing plate to perform corresponding actions. This simplifies the structure of the mahjong machine and greatly saves power costs, and reduces the number of control nodes in the mahjong machine, thereby greatly reducing the failure rate of the mahjong machine.

[0030] Preferably, in the above-mentioned mahjong machine card loading system, the card loading transmission assembly includes:

[0031] The card-raising seat is fixed on the bottom surface of the card-raising plate and is provided with a card-raising curved groove;

[0032] The lifting rocker arm has a fixed end hinged to the frame, and a free end of the lifting rocker arm is provided with a lifting roller, which rolls with the lifting curved groove to drive the lifting plate to flip;

[0033] The card-loading push rod has one end fixedly connected to the card-lifting rocker arm, and the other end of the card-loading push rod is provided with a card-loading roller, which rolls with the card-loading curved groove provided on the transmission cam to drive the card-lifting rocker arm to swing.

[0034] Because the card-lifting roller and the card-lifting curved groove roll in cooperation, when the card-lifting motor drives the transmission cam to rotate, the groove wall of the card-lifting curved groove will push and pull the card-lifting push rod, thereby driving the card-lifting rocker arm to swing; and the swing of the card-lifting rocker arm further drives the card-lifting roller to roll along the card-lifting curved groove, thereby driving the card-lifting plate to flip.

[0035] Preferably, in the above-mentioned mahjong machine card loading system, the card raising curved groove has a positioning notch at a low position and a groove bottom at a high position, and a first limiting corner is formed between the positioning notch and the card raising curved groove;

[0036] The card-lifting roller has a supporting position that is located in the positioning notch to keep the card-lifting plate flush with the mahjong machine panel, and a card-lifting position that rolls along the card-lifting curved groove to flip the card-lifting plate around its flip center axis.

[0037] When the positioning notch is in a low position, the lifting plate can remain flush with the mahjong machine panel when the lifting roller is at the positioning notch, and under the restriction of the first limit corner, the lifting roller can always be in the positioning notch when not subject to external force, ensuring the stable position of the lifting plate; only when the lifting rocker arm swings can the lifting roller pass the first limit corner and roll along the lifting curved groove to the bottom of the groove, so that the lifting plate can drop to receive the mahjong tiles.

[0038] In the above-mentioned mahjong machine loading system, the loading curved groove includes a descending section, a pushing section and a lifting section. The loading roller has a descending position for rolling along the descending section to lower the lifting board, a rolling position for rolling along the pushing section to move the storage board toward the lifting board and push the mahjong tiles horizontally to the pushing position on the lifting board, and a lifting position for rolling along the lifting section to lift the lifting board.

[0039] When the transmission cam rotates and makes the uplift section reach the card roller, in the process of rolling along the uplift section, the groove wall of the uplift section will pull back the card push rod to make the card lifting rocker arm swing toward the side away from the shuffling barrel, and the card lifting roller rolls along the card lifting curved groove toward its positioning notch, The lifting board carries the mahjong tiles and rises to the table.

[0040] In the above-mentioned mahjong machine card loading system, the card pushing transmission assembly includes an S-shaped card pushing track provided on the bottom surface of the card storage plate, the S-shaped card pushing track includes a pushing section and a return section symmetrically arranged about the center of the track midpoint, the end of the pushing section away from the track midpoint is the pushing starting point, and the end of the return section away from the track midpoint is the return starting point, the pushing section and the return section are both arc-shaped, and the central angle of the arc is 90°;

[0041] The transmission cam is provided with a card pushing roller in rolling cooperation with the S-shaped card pushing track at a radial position, and the card pushing roller has a card pushing preparation position for rolling from the midpoint of the track along the pushing section to the starting point of the pushing section, a card pushing position for rolling from the starting point of the pushing section along the pushing section to the midpoint of the track to move the card storage plate toward the card lifting plate, a return preparation position for rolling from the midpoint of the track along the return section to the starting point of the return section, and a return position for rolling from the starting point of the return section along the return section to the midpoint of the track to return the card storage plate to the initial position;

[0042] The upper lifting section comprises a first-stage upper lifting section and a second-stage upper lifting section, and the upper plate roller has a first-stage upper lifting position along the first-stage upper lifting section to lift the lifting plate, and a second-stage upper lifting position along the second-stage upper lifting section to continue lifting the lifting plate and return the storage plate to the initial position.

[0043] When the upper plate roller rolls along the descending section, the pushing plate roller rolls along the pushing section from the midpoint of the track, and the rolling track is concentrically arranged with the rotating track of the transmission cam, so that the storage plate keeps the position unchanged; when the upper plate roller rolls along the pushing section, the pushing plate roller continues to roll along the pushing section to the pushing start point and reversely rolls along the pushing section from the pushing start point to the midpoint of the track, and pushes the storage plate to move towards the lifting plate during the rolling process; in order to adapt to the return preparation position and the return position of the pushing plate roller, the upper lifting section in the upper plate curve groove is divided into the first-stage upper lifting section and the second-stage upper lifting section which are connected in sequence, when the first-stage upper lifting section reaches the upper plate roller due to the rotation of the transmission cam, the pushing plate roller also reaches the midpoint of the track, and rolls along the return section to the return start point with the rotation of the transmission cam, and the rolling track is concentrically arranged with the rotating track of the transmission cam, so that the storage plate keeps the position unchanged; however, the lifting plate is lifted to a certain height to expose the end of the mahjong tiles towards the storage plate above the mahjong machine panel, and the storage plate which keeps the position unchanged can protect the mahjong tiles on the lifting plate from falling back; when the second-stage upper lifting section reaches the upper plate roller due to the rotation of the transmission cam, the pushing plate roller also reaches the return start point, and rolls along the return section to the midpoint of the track with the rotation of the transmission cam, and pushes the storage plate to return to the initial position during the rolling process, waiting for the next pushing of the mahjong tiles; and the lifting plate continues to rise until the lifting plate is flush with the mahjong machine panel.

[0044] Since the lifting plate is arranged on the storage plate after descending, the end face of the mahjong tiles is prone to be in contact with the second length direction side of the lifting plate when the mahjong tiles are transferred from the storage plate to the lifting plate due to the slope and thickness of the lifting plate and the height difference between the storage plate and the lifting plate, and once the risk occurs, the pushing and lifting error of the mahjong tiles will occur.

[0045] In order to solve the above problems, the pushing plate seat is provided with a tile lifting assembly in the mahjong machine tile feeding system, the tile lifting assembly is used to lift the end of the mahjong tiles towards the lifting plate on the storage plate to prevent the mahjong tiles from being stuck at the joint of the storage plate and the lifting plate, and the storage platform is provided with a tile lifting opening for the tile lifting assembly to perform the tile lifting action.

[0046] After the mahjong tiles are lifted towards the lifting plate by the tile lifting assembly, the space is formed between the front end of the mahjong tiles and the storage plate, and when the mahjong tiles are transferred from the storage plate to the lifting plate, the lifting plate is "shovelled" into the space, so that the mahjong tiles and the lifting plate are prevented from being in contact.

[0047] As preferred, in the mahjong tile feeding system, the tile pushing assembly comprises:

[0048] a tile pushing plate movably arranged on the tile pushing base and below the tile pushing opening, and a tile pushing groove is formed on the tile pushing plate;

[0049] a tile pushing rod, one end of which is fixedly connected with the tile lifting arm, and the other end of which is provided with a tile pushing roller which is in rolling engagement with the tile lifting avoiding groove;

[0050] a tile lifting avoiding groove is further formed on the tile lifting base and is in communication with the bottom of the tile lifting curved groove, and the tile lifting avoiding groove extends from the bottom of the tile lifting curved groove to a side away from the tile lifting plate and is in coincidence with the swinging track of the tile lifting arm, and the tile pushing roller rolls along the tile lifting avoiding groove when the tile lifting roller rolls along the tile lifting curved groove, but the tile pushing plate is not lifted and lowered;

[0051] the tile pushing section comprises a tile pushing section, a first tile pushing section and a second tile pushing section which are connected in sequence, and the tile pushing roller has a tile pushing position along the tile pushing section, a tile pushing position along the first tile pushing section and a tile pushing position along the second tile pushing section, wherein, when the tile pushing roller rolls along the tile pushing section, the tile lifting roller rolls along the tile lifting avoiding groove to lift the tile pushing plate, when the tile pushing roller rolls along the first tile pushing section, the tile lifting roller drives the tile storing plate to move towards the tile lifting plate to push the mahjong tiles to the first tile pushing position on the tile lifting plate, and when the tile pushing roller rolls along the second tile pushing section, the tile pushing plate is lifted and the tile storing plate pushes the mahjong tiles to the second tile pushing position on the tile lifting plate.

[0052] Since the tile pushing rod and the tile lifting arm are linked, in order to ensure that the tile pushing rod does not lift and lower the tile pushing plate when the tile lifting roller rolls along the tile lifting curved groove to turn over the tile lifting plate, the tile lifting avoiding groove is arranged on the tile pushing plate and the tile pushing roller is arranged on the tile pushing rod; when the tile lifting roller rolls along the tile lifting curved groove, the tile pushing roller rolls along the tile lifting avoiding groove, but the rolling does not lift and lower the tile pushing plate, and only when the tile pushing roller rolls to the highest point of the tile lifting avoiding groove, the tile pushing plate can be lifted.

[0053] When the transmission cam rotates to drive the tile pushing roller to roll along the tile pushing section, the tile pushing rod drives the tile lifting arm to continue to swing towards the tile washing barrel, and the tile lifting roller enters the tile lifting avoiding groove from the tile lifting curved groove; since the tile lifting avoiding groove is in coincidence with the swinging track of the tile lifting arm, the rolling of the tile lifting roller in the tile lifting avoiding groove does not change the state of the tile lifting plate, but the tile pushing roller lifts the tile pushing plate to lift the mahjong tiles towards the tile lifting plate.

[0054] When the transmission cam rotates and causes the card-loading roller to roll along the first-level card-pushing section, the card-pushing roller rolls along the pushing section from the starting point of the pushing section, driving the card storage plate to move along the supporting surface of the card-pushing seat toward the card-lifting plate, so that the front end of the mahjong tile is attached to the card-lifting plate; during this process, the card-loading push rod, the card-lifting rocker arm and the card-lifting push rod all maintain their positions unchanged, the card-lifting plate remains in its lowered state to receive the mahjong tile, and the card-lifting plate remains in its card-lifting state;

[0055] When the transmission cam rotates and causes the card-loading roller to roll along the secondary card-pushing segment, the card-loading push rod drives the card-lifting rocker arm to swing toward the side away from the shuffling barrel, and the card-lifting roller returns from the top card avoidance slot to the card-lifting curved slot and remains at the bottom of the card-lifting curved slot (the position remains unchanged). The top card roller also releases the support for the top card board and remains at the top card slot of the card-lifting avoidance slot (the position remains unchanged); in this process, the card-pushing roller continues to roll along the pushing segment to the midpoint of the track, pushing the mahjong tiles completely onto the card-lifting board, completing one card pushing.

[0056] Compared with the prior art, the beneficial effects of the present invention are embodied in:

[0057] (1) In the present invention, the tile raising plate can be flipped relative to the mahjong machine panel to achieve sloped tile discharging, but its flipping center line extends along the length direction of the tile raising plate, so the mahjong tiles from the tile storage plate are received from the length direction side; because the tiles are raised from the length direction side, the mahjong tiles on the tile storage plate can be pushed onto the tile raising plate in one step, which greatly shortens the tile loading distance, saves tile loading time, and improves tile loading efficiency.

[0058] (2) Since the card loading system of the present invention does not require long-distance pushing of cards, the size of the mahjong machine can be greatly reduced without changing other internal structures of the mahjong machine. The size of the shuffling bucket can be increased without changing the size of the mahjong machine. A larger card raising board can be provided without changing the size of the mahjong machine and the shuffling bucket, thereby being able to accommodate more mahjong tiles and provide players with more ways to play.

[0059] (3) The present invention hinges the first longitudinal side of the card-lifting board to the mahjong machine panel, so that the flip center axis of the card-lifting board is located on the first longitudinal side, so that the second longitudinal side has a larger flipping amplitude, and the card-lifting board structure is also more compact; in particular, the first longitudinal side of the card-lifting board will not be tilted above the mahjong machine table top, and will not be squeezed with the mahjong machine panel when it falls back, so the flocked tablecloth on the card-lifting board can be laid with the same area as the card-lifting board, and there is no gap between the card-lifting board and the mahjong machine panel, making the mahjong machine table top more flat, not only does it not affect the card playing, but also greatly improves the aesthetics of the table top.

[0060] (4) In the present invention, the card-loading drive mechanism can drive the card-lifting board to descend or lift up, and can also push the mahjong tiles on the card-storage board to the card-lifting board when the card-lifting board descends. This not only greatly saves the power cost required for card loading, but also reduces the number of control nodes in the mahjong machine, thereby reducing the failure rate of the mahjong machine.

[0061] (5) The present invention sets the card storage platform to be inclined upward from the side away from the card raising board to the side close to the card raising board. Then, when the card raising board descends, the closer the angle between the card raising board and the card storage board is to 180°, the more conducive it is to reducing the translational obstruction caused by the card raising board to the mahjong tiles.

[0062] (6) In the present invention, the transfer method of mahjong tiles from the card storage board to the card raising board can be: the card loading drive mechanism drives the card storage board to move toward the card raising board to push the mahjong tiles onto the card raising board; or it can be: the card storage board remains in the same position, and the card loading drive mechanism directly pushes the mahjong tiles on the card storage board to move toward the card raising board; the first method is more preferred, because when the card storage board always remains in the same position, the area of ​​the mahjong machine always remains unchanged; and when the card storage board can change its position, the area of ​​the mahjong machine has the opportunity to be reduced. When the mahjong machine needs to be packaged and transferred, it can be packaged in a smaller package, thereby saving transportation cost and transportation space; moreover, the card raising board can be set closer to the center of the shuffling barrel to facilitate players to grab cards.

[0063] (7) In the present invention, the card pushing seat is further provided with a card pushing component for pushing the mahjong cards on the card storage board toward one end of the card raising board. After the mahjong cards are pushed upward toward one end of the card raising board by the card pushing component, an escape space is formed between the front end of the mahjong cards and the card storage board. When the mahjong cards are transferred from the card storage board to the card raising board, the card raising board will be "scooped" up by the mahjong cards because they are included in the escape space, thereby preventing the mahjong cards and the card raising board from being pressed tightly.

[0079] The technical solution of the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods. Example

[0080] like Figures 1-15 As shown, this embodiment provides a mahjong machine loading system, including a frame, on which are provided a stacking device A and a card pushing device B. The stacking device A is used to stack the tiles and push the stacked tiles one by one onto the card storage plate 12, while the card pushing device B is used to deliver the mahjong tiles on the card storage plate 12 to the mahjong machine panel 100.

[0081] like Figure 1 and Figure 2 As shown, the stacking device A includes a stacking mechanism 1, which includes a stacking seat 11. A card feeding channel 402 is formed in the card feeding bracket 401 of the card feeding mechanism 400. The mahjong tiles sucked up from the shuffling barrel are all sent to the stacking seat 11 at the card outlet of the card feeding channel 402 through the card feeding channel 402 to be stacked into card piles.

[0082] A stacking mechanism 2 and a card storage plate 12 are respectively provided on opposite sides of the stacking card seat 11. The stacking mechanism 2 includes a card pushing machine head box 21 fixed on the frame. The card pushing machine head box 21 is provided with a card pushing head 22 for pushing the card piles on the stacking card seat 11 one by one onto the card storage plate 12. The way in which the card pushing head 22 implements the card pushing action is completed using a conventional structure, so it will not be repeated in this embodiment.

[0083] like Figure 3 As shown, in this embodiment, a card receiving platform 200 is formed on the card stacking seat 11. Taking the card receiving two layers as an example, the height difference between the card receiving platform 200 facing the card delivery channel 402 and the card delivery channel 402 should be equivalent to the thickness of a mahjong tile. The height difference can be slightly larger than the thickness of a mahjong tile, but is not allowed to be less than the thickness of a mahjong tile, otherwise it will affect the normal delivery of the second mahjong tile.

[0084] When the card pile has two layers, the card stacking seat 11 can be fixedly installed at the card output end of the card delivery channel 402, or it can be lifted and set at the card output end of the card delivery channel 402. In actual circumstances, it can be fixedly set at the card output end of the card delivery channel 402; when the card pile has three layers or more, it is preferred to lift and set the card stacking seat 11 at the card output end of the card delivery channel 402.

[0085] At the exit of the card delivery channel 402, mahjong tiles fall in a plunging manner. If the card receiving platform 200 is horizontally positioned, the front end of the mahjong tile will continue to rush forward due to inertia after contacting the card receiving platform 200, causing the tile to fall. To solve this problem, the present embodiment tilts the card receiving platform 200 downward from the side closest to the card delivery channel 402 to the side away from the card delivery channel 402. In addition, a card stacking guardrail 300 is formed on the side of the card receiving platform 200 away from the card delivery channel 402.

[0086] Since the tilt direction of the card receiving platform 200 is consistent with the tilt direction of the mahjong tiles when they fall, when the mahjong tiles fall onto the card receiving platform 200, the entire bottom surface of the mahjong tiles can contact the card receiving platform 200 at the same time, or the bottom surface of the mahjong tiles can contact the card receiving platform 200 at a small angle, and then slide along the card receiving platform 200 for a certain distance before resting on the card stacking guardrail 300; the second mahjong tile is stacked in the same way, so that the tiles can be prevented from being dropped while the card receiving platform 200 remains static.

[0087] In this embodiment, the tilt angle of the card receiving platform 200, i.e., the angle between the card receiving platform 200 and the horizontal plane, can be set between 5° and 60°, preferably between 10° and 30°; this is preferably close to the tilt angle of the falling mahjong tiles. Since the stacking base 11 is tilted, in order to facilitate the transfer of mahjong tiles from the stacking base 11 to the card storage plate 12, the card storage plate 12 also has the same tilt as the stacking base 11.

[0088] That is, the card storage plate 12 of this embodiment includes a card storage platform 12a located on the same plane as the card receiving platform 200, and a card storage guardrail 12b located on the same plane as the card stacking guardrail 300. The card storage guardrail 12b is also fixed to one side of the card storage platform 12a to prevent mahjong tiles from sliding off the card storage platform 12a. The side opposite to the card storage guardrail 12b is the card outlet of the card storage platform 12a.

[0089] In this embodiment, the card storage plate 12 is movable relative to the tile raising plate 3. Specifically, the card storage plate 12 includes a tile storage position located to the side of the tile receiving platform 200 for receiving mahjong tiles, and a tile pushing position that moves toward the tile raising plate 3 to push mahjong tiles out of the tile outlet. When the card storage plate 12 is movable toward the tile raising plate 3, the tile raising plate 3 can be positioned closer to the center of the shuffling bucket, making it easier for players to grab tiles. This also greatly increases the possibility of retracting the periphery of the mahjong machine, facilitating the use of smaller packaging boxes for the mahjong machine.

[0090] Depend on Figure 4 and Figure 8 It can be seen that the top surface of the card pushing seat 6 in this embodiment is the support surface of the card storage plate 12. The card storage plate 12 moves along the support surface under the drive of the card loading drive mechanism 5. The inclination angle of the support surface is consistent with the inclination angle of the card storage plate 12. Figure 2 、 Figure 3 and Figure 4As shown, in the direction of movement of the card storage board 12, the support surface of the card pushing seat 6 is narrower than that of the card storage board 12. The card storage board 12 at the starting point of pushing cards rests on the support surface on the side closest to the card raising board 3, while the side away from the card raising board 3 is suspended in the air. In addition, the card loading drive mechanism 5 is arranged on the side of the card pushing seat 6 facing the card raising board 3. Therefore, when the card storage board 12 moves along the support surface toward the card raising board 3, the space outside the card pushing seat 6 is gradually vacated, thereby greatly retracting the card pushing seat 6 into the outer periphery of the mahjong machine, making it easier to use a smaller packaging box to pack the mahjong machine.

[0091] Since the stacking seat 11 is on the same horizontal plane as the card storage plate 12, in order to facilitate the overall retraction of the mahjong machine's periphery, this embodiment also provides a compressible space for stacking cards on the stacking seat 11. Specifically, the card receiving platform 200 and the stacking guardrail 300 in this embodiment are not completely rigid surfaces, but rather have both rigid and flexible portions.

[0092] Specifically, by Figure 1 and Figure 2 and Figure 3 It can be seen that the card storage guardrail 12b has a backrest plate 11a extending toward the card stacking seat 11. The bottom end of the backrest plate 11a does not extend to the plane where the card receiving platform 200 is located. Instead, a first avoidance opening 11b is left to prevent the backrest plate 11a from colliding with the card feeding bracket 11 due to the movement of the card storage plate 12. The height of the first avoidance opening 11b is set at 1 cm. The top of the card pushing machine head box 21 is fixedly provided with an auxiliary card holding plate 11c, which is also relatively narrow, so that a second avoidance opening 11d is formed between the auxiliary card holding plate 11c and the backrest plate 11a for preventing the backrest plate 11a from colliding with the auxiliary card holding plate 11c due to its movement with the card storage plate 12; a flexible member 11e is fixedly connected between the backrest plate 11a and the auxiliary card holding plate 11c. When the backrest plate 11a moves with the card storage plate 12, the flexible member 11e can bend arbitrarily. Only when the mahjong tiles fall onto the flexible member 11e, the flexible member 11e is stretched due to the squeezing of the mahjong tiles, and together with the auxiliary card holding plate 11c, it forms the card holding platform 200, and together with the backrest plate 11a, it forms the card stacking guardrail 300. At this time, the card holding platform 200 and the card storage platform 12a are finally formed.

[0093] In this embodiment, the flexible member 11e can be made of fabric. Furthermore, to create a smooth tile-receiving platform 200, the flexible member 11e preferably completely covers the platform 200, preventing any unevenness between the flexible member 11e and the auxiliary tile-receiving plate 11c. Obviously, at the end of the stacking guardrail 300, the flexible member 11e can also be positioned at the same height as the tile piles to ensure smooth tile transfer. In this case, it would be more appropriate to bond the flexible member 11e to the auxiliary tile-receiving plate 11c or the backing plate 11a via an adhesive backing layer. Because the tile-receiving platform 200 is tilted, a tile guard 11f can optionally be provided at the top of the backing plate 11a, tilted toward the tile-receiving side of the tile-receiving platform 200, to protect the mahjong tiles. This tile guard 11f is preferably integrally formed with the backing plate 11a. A similar tile guard 12c can also be provided on the tile-receiving guardrail 12b.

[0094] To further prevent the backrest plate 11a from colliding with the auxiliary card support plate 11c or the card delivery bracket 11, this embodiment sets the angle between the planes of the backrest plate 11a and the auxiliary card support plate 11c to be greater than 90°, thereby offsetting the inclination of the auxiliary card support plate 11c. Obviously, this angle should not be too large, as it would affect subsequent card advancement; it is preferably set at approximately 100°. Accordingly, the card storage platform 12a and the card storage guardrail 12b of the card storage plate 12 also have the same angle, ensuring smooth transfer of card piles from the stacking base 11 to the card storage plate 12.

[0095] Of course, it is also feasible to set the card stacking seat 11 not to move synchronously with the card storage plate 12. In this case, there is no need to set the first avoidance opening 11b and the second avoidance opening 11d. The backrest plate 11a and the auxiliary card holding plate 11c can be directly connected and fixed or integrally formed to form a rigid and permanent card holding platform 200 and card stacking guardrail 300. At this time, the outer periphery of the mahjong machine cannot be retracted as a whole.

[0096] like Figure 4 Shown, combined Figure 1 As can be seen, in this embodiment, the card-lifting device B includes a card-lifting plate 3 having a first longitudinal side 31 and a second longitudinal side 32 disposed opposite each other. The first longitudinal side 31 is hingedly connected to the mahjong machine panel 100 via a hinge 4, while the second longitudinal side 32 is tilted about the first longitudinal side 31 by the card-lifting drive mechanism 5. Specifically, when the card-lifting plate 3 is tilted upward, it remains flush with the mahjong machine panel 100; when it is lowered, it rests on the card storage plate 12.

[0097] In this embodiment, the angle between the card raising plate and the card storing plate after it is lowered is set to be between 90° and 180° (excluding 90° and 180°), more preferably between 120° and 180° (including 120° and 180°), and most preferably between 150° and 180° (including 150° and 180°).

[0098] like Figure 4 and Figure 5 As shown, the card loading drive mechanism 5 includes a card loading motor 51 , on the output shaft of which a transmission cam 52 is fixedly mounted, and the card loading plate 3 and the transmission cam 52 are transmitted via a card loading transmission assembly 53 .

[0099] The card-raising transmission assembly 53 includes a card-raising seat 531 fixedly mounted on the bottom surface of the card-raising plate 3. Figure 10 As shown, a lifting curved groove 531a is formed on the side of the lifting seat 531; the fixed end of the lifting rocker arm 532 is hinged to the frame, and the free end is provided with a lifting roller 533 that rolls with the lifting curved groove 531a. The lifting roller 533 rolls along the lifting curved groove 531a to drive the lifting plate 3 to flip; and the rolling power of the lifting roller 533 comes from the swing of the lifting rocker arm 532, and the swing of the lifting rocker arm 532 is driven by the lifting push rod 534.

[0100] In this embodiment, the card-loading push rod 534 drives the card-lifting rocker arm 532 to swing as follows: one end of the card-loading push rod 534 is fixedly connected to the card-lifting rocker arm 532, and the other end is provided with a card-loading roller 535, which is in contact with the card-loading curved groove 521 (such as the card-loading curved groove 521) provided on the transmission cam 52. Figure 6 When the transmission cam 52 rotates, the card-loading roller 535 rolls along the card-loading curved groove 521 and pushes and pulls the card-loading push rod 534, so that the card-loading push rod 534 can drive the card-lifting rocker arm 532 to swing.

[0101] In order to ensure the smooth lifting of the card lifting plate 3, this embodiment provides two card lifting seats 531 and two card lifting rocker arms 532 on each card lifting plate 3. The two card lifting rocker arms 532 are linked by a linkage rod 536, and the card lifting push rod 534 is fixedly connected to the linkage rod 536.

[0102] In this embodiment, each of the tile lifting rocker arms 532 comprises a swing support 532a having a through hole in the middle end for facilitating the penetration of the linkage rod 536, and two extension arms 532b are respectively inserted into the two ends of the swing support 532a, one of which is hinged to the frame through a hinge support 532c, and the other of which is provided with a tile lifting roller 533. The structure of the tile lifting rocker arm 532 can adjust the length of the extension arm 532b without changing the connection structure between the tile lifting rocker arm 532 and the linkage rod 536, so as to adapt to mahjong machines of different specifications.

[0103] As shown in Figure 10 , the tile lifting curve groove 531a on the tile lifting seat 531 has a positioning notch 531aa at a low position and a groove bottom 531ab at a high position, and a first limiting corner 531ac is formed between the positioning notch 531aa and the tile lifting curve groove 531a. When the tile lifting roller 533 is in the positioning notch 531aa (as shown in Figure 11 ), the tile lifting plate 3 is flush with the mahjong machine panel 100, and the tile lifting roller 533 can be kept in the positioning notch 531aa when it is not under stress due to the limitation of the first limiting corner 531ac, ensuring the stable position of the tile lifting plate 3; when the tile lifting rocker arm 532 swings, the tile lifting roller 533 can roll along the tile lifting curve groove 531a by passing the first limiting corner 531ac, at this time, the tile lifting plate 3 is lowered and placed on the tile storage plate 12 (as shown in Figure 12 ), waiting for the tiles to be pushed.

[0104] In this embodiment, the included angle between the tile lifting plate 3 and the tile storage plate 12 after the tile lifting plate 3 is lowered is between 90° and 180° (not including 90° but including 180°), preferably between 110° and 180° (including 110° and 180°), and more preferably between 150° and 180° (including 150° and 180°); within this range, the larger the included angle between the two, the more stable the transfer of mahjong tiles from the tile storage plate 12 to the tile lifting plate 3.

[0105] As shown in Figure 8 , in combination with Figure 5 , it can be seen that the tile storage plate 12 is movably mounted on the tile pushing seat 6 and can slide along the support surface formed by the tile pushing seat 6, when the tile storage plate 12 moves towards the tile lifting plate 3, the tile lifting plate 3 scoops up the mahjong tiles. As shown in Figure 8 and Figure 9 , in order to ensure that the movement of the tile storage plate 12 along the support surface does not deviate, the bottom surface of the tile storage plate 12 is provided with a guide 12d penetrating the tile pushing seat 6, and the guide 12d adopted in this embodiment is two guide rods.

[0106] As shown in Figure 5 and Figure 6 As shown, the bottom surface of the card storage plate 12 is formed with a series of recessed areas 12e arranged along the length of the card storage plate 12. Each recessed area 12e is strip-shaped and extends in the same direction as the movement of the card storage plate 12. The provision of the recessed areas 12e significantly reduces the contact area between the card storage plate 12 and the card pusher 6, thereby reducing both the resistance to the movement of the card storage plate 12 and unnecessary wear between the two.

[0107] The recessed area 12e can be provided only on the bottom surface of the card storage platform 12a, or it can be extended from the bottom surface of the card storage platform 12a to the back surface of the card storage guardrail 12b; in this way, the overall weight of the card storage plate 12 can be greatly reduced while ensuring the strength of the card storage guardrail 12b.

[0108] In this embodiment, the card pushing action of the card storage plate 12 is also driven by the transmission cam 52. By setting a card pushing transmission component 54 between the transmission cam 52 and the card storage plate 12, the synchronous driving of the card pushing and raising mechanism 5 can be achieved.

[0109] Therefore, if Figure 6 As shown, the card-lifting curved groove 521 of the transmission cam 52 includes a descending section 521a, a card-pushing section 521b and a card-lifting section 521c connected in sequence. When the transmission cam 52 rotates and the descending section 521a reaches the card-lifting roller 535, the card-lifting roller 535 rolls along the descending section 521a, causing the card-lifting rocker arm 532 to swing toward the shuffling barrel, and the card-lifting roller 533 rolls from the positioning notch 531aa along the card-lifting curved groove 531a to the groove bottom 531ab, thereby causing the card-lifting plate 3 to descend; when the transmission cam 52 rotates and the card-pushing section 521a reaches the card-lifting roller 535, the card-lifting roller 535 rolls along the descending section 521a, causing the card-lifting rocker arm 532 to swing toward the shuffling barrel, and the card-lifting roller 533 rolls from the positioning notch 531aa along the card-lifting curved groove 531a to the groove bottom 531ab, thereby causing the card-lifting plate 3 to descend; After 521b reaches the card-loading roller 535, the card-loading roller 535 rolls along the card-pushing segment 521b, and the card storage plate 12 moves toward the card-lifting plate 3 under the drive of the card-pushing transmission component 54, and pushes the mahjong tiles flatly onto the card-lifting plate 3; when the transmission cam 52 rotates and causes the tilting segment 521c to reach the card-loading roller 535, the card-loading roller 535 rolls along the tilting segment 521c, causing the card-lifting rocker arm 532 to swing back toward the shuffling barrel, and the card-lifting roller 533 rolls from the groove bottom 531ab along the card-lifting curved groove 531a to the positioning notch 531aa, causing the card-lifting plate 3 to tilt up to be flush with the mahjong machine panel 100.

[0110] like Figure 9 Shown, combined Figure 4It can be seen that the card pushing transmission component 54 of this embodiment includes an S-shaped card pushing track 541 provided on the bottom surface of the card storage plate 12, and the S-shaped card pushing track 541 includes a pushing section 541b and a return section 541c symmetrically arranged about the center point 541a of the track. The pushing section 541b and the return section 541c are both arc-shaped and the central angles of the arcs are both 90°, wherein the end of the pushing section 541b away from the track midpoint 541a is the pushing starting point 541d, and the end of the return section 541c away from the track midpoint 541a is the return starting point 541e; Figure 7 and Figure 9 As shown, the transmission cam 52 has a card pushing roller 542 in radial position that rolls with the S-shaped card pushing track 541 , and the card pushing roller 542 and the card loading curved groove 521 are respectively located on two opposite sides of the transmission cam 52 .

[0111] In this embodiment, the card pushing roller 542 has four motion processes: card pushing preparation position (from the midpoint of the track to the starting point of the pushing process), card pushing position (from the starting point of the pushing process to the midpoint of the track), return preparation position (from the midpoint of the track to the starting point of the return process) and return position (from the starting point of the return process to the midpoint of the track); corresponding to this, such as Figure 6 As shown, the upward tilting section 521c in the upper curved groove 521 is also divided into a first-level upward tilting section 521ca and a second-level upward tilting section 521cb.

[0112] When the card-loading roller 535 rolls along the descending section 521a, the card-pushing roller 542 rolls from the midpoint 541a of the track along the pushing section 541b to the pushing starting point 541d, ready to push the card; in this process, the rolling trajectory of the card-pushing roller 542 is exactly concentric with the rotation trajectory of the transmission cam 52, so the card storage plate 12 keeps its position unchanged; when the card-loading roller 535 rolls along the pushing section 521b, The card pushing roller 542 rolls from the pushing starting point 541d along the pushing section 541b to the track midpoint 541a to move the card storage plate 12 toward the card raising plate 3, completing the card pushing; when the card loading roller 535 rolls along the first-level lifting section 521ca, the card raising rocker 532 can only drive the card raising plate 3 to lift up until the mahjong tiles are exposed on the mahjong machine panel 100 toward the side of the card storage guardrail 300, and the card pushing roller 542 rolls from the track midpoint 541a along the return section 541c to the return starting point 541e, preparing to return; in this process, due to the card pushing The rolling track of the roller 542 is exactly concentric with the rotation track of the transmission cam 52, so the card storage board 12 also keeps its position unchanged and is at its pushing end point to protect the mahjong tiles on the card raising board 3; when the card raising roller 535 rolls along the secondary lifting section 521cb, the card raising board 3 continues to lift until it is flush with the mahjong machine panel 100, and the card pushing roller 542 rolls from the return starting point 541e along the return section 541c to the track midpoint 541a to return the card storage board 12 to the initial position, waiting for the tile pile from the stacking seat 11. Affected by the slope and thickness of the card raising board 3 and the possible height difference between the card raising board 3 and the card storage board 12, there is more or less a height difference between the top surface of the card raising board 3 and the top surface of the card storage board 12, and the existence of this height difference will affect the smooth transfer of mahjong tiles. In order to eliminate this influence, as Figure 5 and Figure 8 As shown, in this embodiment, the pusher seat 6 is provided with a push-up assembly 55 for pushing one end of a mahjong tile upward toward the raising plate 3 to prevent the mahjong tile from getting stuck at the junction of the storage plate 12 and the raising plate 3. The storage plate 12 is provided with a push-up opening 12f for facilitating the push-up operation of the push-up assembly 55. The distance between the push-up opening 12f and the raising plate 3 should be less than the length of a mahjong tile. The push-up opening 12f is strip-shaped, and its length extends in the same direction as that of the storage plate 12. When mahjong tiles are stored on the storage plate 12, all mahjong tiles can be exposed at the push-up opening 12f and pushed up.

[0113] Depend on Figure 8It can be seen that the top surface of the pusher seat 6 in this embodiment serves as the support surface for the card storage plate 12, and the inclination angle of the support surface is consistent with the inclination angle of the card storage plate 12. The top surface of the pusher seat 6 is formed with a receiving groove 61, and a card-lifting plate 551 is movably mounted in the receiving groove 61. The card-lifting push rod 553 rotatably connected to the card-lifting plate 551 drives the card-lifting plate 551 to slide upward along the receiving groove 61, and the card-lifting plate 551 can extend from the card-lifting opening 12f to lift the mahjong tiles upward toward one end of the card-lifting plate 3.

[0114] like Figure 4 and Figure 8 As shown, in this embodiment, the top of the top card plate 551 has a top card portion 551b that is adapted to the top card opening 12f, and a limiting step 551a is formed between the two ends of the top card portion 551b and the top card plate 551. When the top card plate 551 rises to the point where the limiting step 551a conflicts with the bottom surface of the card storage plate 12, the top card plate 551 can no longer continue to rise, thereby achieving the purpose of limiting the top card height of the top card plate 551.

[0115] like Figure 4 、 Figure 5 and Figure 8 As shown, in order to facilitate the transmission of the card push rod 553 and the card push plate 551, the side of the card pusher 6 of this embodiment is also formed with a plurality of through holes 62 connected to the accommodating groove 61; and the card pusher plate 551 has a connecting ear 551c extending from one of the through holes 62 to the outside of the card pusher 6, and the card push rod 553 is rotatably connected to the connecting ear 551c.

[0116] like Figure 5 and Figure 8 As shown, in this embodiment, the card-lifting push rod 553 is rotatably connected to the connecting ear 551c in the following manner: a card-lifting avoidance groove 552 is formed on the connecting ear 551c, and the card-lifting push rod 553 includes a push rod joint 553a and a push arm 553b fixedly connected to the push rod joint 553a, and the push rod joint 553a is fixedly installed on the end of the linkage rod 536, so that the linkage rod 536, the card-lifting rocker arm 532 and the card-lifting push rod 553 are linked; and the free end of the push arm 553b is provided with a card-lifting roller 554 that rolls with the card-lifting avoidance groove 552.

[0117] In accordance with the number of the card-top push rods 553 , two connecting ears 551 c are also provided on the card-top plate 551 of this embodiment to ensure that the card-top plate 551 can be smoothly lifted and lowered along the accommodating groove 61 .

[0118] like Figure 11As shown, the card-raising avoidance groove 552 in this embodiment has a groove bottom 522a at a low position and a card-top slot 522b at a high position. The card-raising avoidance groove 552 can be circumferentially closed, or an opening 522d can be provided at the card-top slot 522b to facilitate the card-top roller 554 to enter the card-raising avoidance groove 552. At this time, it should be ensured that a second limiting corner 522c is formed between the opening 522d and the card-top slot 522b, so that the card-top roller 554 can drive the card-top plate 551 to rise and fall along the accommodating groove 61 at the card-top slot 522b without separating from the card-raising avoidance groove 552 from the opening 522d.

[0119] Since the card push rod 553 is linked to the card raising rocker arm 532, when the card raising rocker arm 532 swings, the card push rod 553 also changes position. Figure 11 As shown, when the card-raising roller 533 is at the positioning notch 531aa of the card-raising curved groove 531a, the card-top roller 554 is at the groove bottom 531ab of the card-raising avoidance groove 552; Figure 12 As shown, when the card-raising roller 533 rolls from the positioning slot 531aa along the card-raising curved slot 531a to the slot bottom 531ab, the card-lifting roller 554 also rolls from the slot bottom 522a of the card-raising avoidance slot 552 to the card-lifting slot 522b, but this rolling will not cause the card-lifting plate 551 to rise or fall. When the card-lifting roller 554 reaches the card-lifting slot 522b, the card-lifting roller 554 also reaches the card-lifting slot 522b and is ready to lift the card; as shown in FIG. Figure 10 and Figure 14 and Figure 15 As shown, a top card avoidance groove 555 is also formed on the card raising seat 531, which is connected to the bottom of the card raising curved groove 531a. The top card avoidance groove 555 extends from the groove bottom 531ab of the card raising curved groove 531a to the side away from the card raising plate 3 and coincides with the swing trajectory of the card raising rocker arm 532. When the card raising rocker arm 532 continues to swing, the card raising roller 533 enters the top card avoidance groove 555 from the card raising curved groove 531a. Since the top card avoidance groove 555 coincides with the swing trajectory of the card raising rocker arm 532, the rolling of the card raising roller 533 in the top card avoidance groove 555 will not cause the state of the card raising plate 3 to change, but will cause the top card push rod 553 to pull with the top card notch 522b, so that the top card plate 551 rises along the accommodating groove 61 to implement the card raising action. At this time, the card storage plate 12 starts to push the cards.

[0120] In order to avoid the top plate 551 affecting the pushing of the mahjong tiles by the tile storage plate 12, the embodiment is configured such that after the front end of the mahjong tiles on the tile storage plate 12 is overlapped on the tile lifting plate 3, the top plate 551 can be lowered to release the support of the mahjong tiles. However, before this, the top plate 551 always maintains the top plate posture, and the tile storage plate 12 still moves during the top plate process. In order to avoid the top plate 551 hindering the movement of the tile storage plate 12 in this stage, as shown in Figure 8 , the width of the top plate port 12f is greater than the width of the top plate 551. When the tile storage plate 12 moves to push the tiles, the top plate 551 moves from the side of the top plate port 12f close to the tile outlet of the tile storage plate 12 to the side of the top plate port 12f away from the tile outlet of the tile storage plate 12, and then is lowered to release the support of the mahjong tiles, and the tile storage plate 12 continues to push the tiles until the mahjong tiles are completely transferred to the tile lifting plate 3.

[0121] As shown in Figure 15 , the top plate part 551b is formed with a top plate surface 551d, which is arranged downwardly and obliquely from the top end of the top plate part 551b to the tile storage plate 12, the oblique direction of the top plate surface 551d is opposite to the advancing direction of the mahjong tiles on the tile storage plate 12, and the slope of the top plate surface 551d is greater than the slope of the tile storage platform 12a. In this way, it can not only ensure that the top plate 551 does not hinder the tile storage plate 12 to continue pushing the tiles when it is lowered, but also ensure that the contact area between the mahjong tiles and the top plate surface 551d becomes larger and larger as the mahjong tiles continue to advance, so that the mahjong tiles can be kept stable during the top plate process.

[0122] Correspondingly, as shown in Figure 6As shown, in the card-lifting curved groove 521 of the transmission cam 52, the present embodiment sets the card-pushing segment 521b to include a top card segment 521ba, a first-level card-pushing segment 521bb and a second-level card-pushing segment 521bc connected in sequence. When the transmission cam 52 rotates and causes the top card segment 521ba to reach the card-lifting roller 535, the card-lifting roller 535 rolls along the top card segment 521ba to cause the card-lifting rocker arm 532 to swing toward the shuffling barrel, and the card-lifting roller 533 rolls from the card-lifting curved groove 531a to the top card avoidance groove 555, causing the top card push rod 535 to push the top card. 53 lifts the top card plate 551; when the transmission cam 52 rotates and the first-level card pushing segment 521bb reaches the card loading roller 535, the card loading roller 535 rolls along the first-level card pushing segment 521bb. At this time, the card lifting rocker 532 keeps its position unchanged, and the card pushing roller 542 rolls along the pushing segment 541b from the pushing starting point 541d, pushing the mahjong tile part flatly onto the card lifting plate 3; when the transmission cam 52 rotates and the second-level card pushing segment 521bc reaches the card loading roller 535, the card loading roller 535 rolls along the second-level card pushing segment 521bc The card raising rocker arm 532 swings to the side away from the shuffling barrel, and the card raising roller 533 returns to the card raising curved groove 531a from the card raising avoidance groove 555, and the card raising push rod 553 immediately releases the support for the card raising plate 551; during this process, the card pushing roller 542 continues to roll along the pushing section 541b to the midpoint 541a of the track, pushing the mahjong tiles completely onto the card raising plate 3.

[0123] Since the opening width of the top card opening 12f on the card storage plate 12 is relatively large, in order to ensure the strength of the card storage plate 12, as shown in FIG. Figure 8 As shown, the inner edge of the opening 12f is provided with a plurality of reinforcing ribs 12g arranged along the length of the opening 12f, and the top plate 551 is formed with notches 551e that match the reinforcing ribs 12g. The width of the reinforcing ribs 12g should be smaller than the width of the mahjong tiles to prevent the reinforcing ribs 12g from interfering with the support of the top plate 551 on the mahjong tiles.

[0124] like Figure 6As shown, the card loading curved groove 521 includes an outer curved surface 521d and an inner curved surface 521e arranged opposite each other. As the card loading roller 535 rolls along the card loading curved groove 521, the wheel surface of the card loading roller 535 always rolls in contact with the outer curved surface 521d and the inner curved surface 521e. Specifically, at the card loading starting point 521f of the card loading curved groove 521 and within the first-stage card pushing section 521bb, the outer curved surface 521d and the inner curved surface 521e are perpendicular to the groove bottom surface. At all other locations, the outer curved surface 521d and the inner curved surface 521e are inclined relative to the central axis of the transmission cam 52, thereby enabling the pushing and pulling of the card loading push rod 534. The inclination directions of the outer curved surface 521d and the inner curved surface 521e in the descending section 521a and the card-pushing section 521ba are different from those in the secondary card-pushing section 521bc and the card-lifting section 521c, which is consistent with the rolling direction of the card-lifting roller 533. The inclination angles of the outer curved surface 521d and the inner curved surface 521e gradually increase from the card-lifting starting point 521f to the end of the card-lifting section 521ba; while the inclination angles of the outer curved surface 521d and the inner curved surface 521e gradually decrease from the starting point of the secondary card-pushing section 521bc to the card-lifting starting point 521f. At the end of the card-lifting section 521ba and the starting point of the secondary card-pushing section 521bc, the inclination angles of the outer curved surface 521d and the inner curved surface 521e are exactly the same as the total swing angle of the card-lifting rocker 532.

[0125] The working principle of the mahjong machine card loading system in this embodiment is as follows:

[0126] The mahjong tiles sucked up from the shuffling bucket by the suction wheel are delivered one by one to the stacking base 11 through the card delivery channel 402. The mahjong tiles fall from the card delivery end of the card delivery channel 402 in an inclined posture onto the flexible member 11e. Under the pressure of the mahjong tiles, a card receiving platform 200 and a card stacking guardrail 300 are formed on the flexible member 11e. The card receiving platform 200 is also inclined downward from the card receiving side toward the card stacking guardrail 300 side, in the same posture as the falling mahjong tiles, so that the cards will not be pushed. The stacked tile piles are pushed one by one by the pushing head 22 onto the card storage board 12. After the preset number of tile piles is stored on the card storage board 12, the card loading can begin.

[0127] When loading a card, the loading motor 51 is started, and the transmission cam 52 rotates accordingly. During the rotation of the transmission cam 52, the loading curved groove 521 and the card pushing roller 542 on both sides of the transmission cam 52 respectively perform corresponding actions under the drive of the transmission cam 52;

[0128] The card raising roller 533 then rolls from the positioning notch 531aa along the card raising curved groove 531a to the groove bottom 531ab, thereby lowering the card raising plate 3 until the card raising plate 3 is placed on the card storage plate 12. In this process, the card pushing roller 554 also rolls from the groove bottom 552a of the card raising avoidance groove 552 to the card pushing notch 522b, but this rolling will not cause the card pushing plate 551 to rise or fall. When the card pushing roller 554 reaches the card pushing notch 522b, the card pushing roller 554 is ready to push the card.

[0129] Afterwards, the top card segment 521ba reaches the card-lifting roller 535, and the inner curved surface 521e continues to squeeze the card-lifting roller 535, so that the card-lifting push rod 534 drives the card-lifting rocker arm 532 to continue to swing toward the shuffling barrel, and the card-lifting roller 533 enters the top card avoidance groove 555 from the card-lifting curved groove 531a. Since the top card avoidance groove 555 coincides with the swing trajectory of the card-lifting rocker arm 532, the rolling of the card-lifting roller 533 in the top card avoidance groove 555 will not cause the state of the card-lifting plate 3 to change, but it will cause the top card push rod 553 to The card pushing roller 542 is pulled against the card pushing notch 522b, causing the card pushing plate 551 to rise along the accommodating groove 61 and push the mahjong tiles upward toward one end of the card raising plate 3. As the card loading roller 535 rolls along the descending section 521a and the card pushing section 521ba, the card pushing roller 542 rolls from the track midpoint 541a of the S-shaped card pushing track 541 along the pushing section 541b to the pushing starting point 541d, ready to push the cards. During this process, the rolling trajectory of the card pushing roller 542 is exactly concentric with the rotation trajectory of the transmission cam 52, so that the card storage plate 12 remains in the same position.

[0130] Subsequently, the first-level pushing segment 521bb reaches the card-loading roller 535, and the card-loading roller 535 then rolls along the first-level pushing segment 521bb, but this rolling does not drive the card-lifting rocker arm 532 to swing. Therefore, the card-lifting plate 3 remains in its lowered state waiting to receive the mahjong tile, and the card-lifting plate 551 remains in the card-lifting state; but the card-pushing roller 542 rolls along the pushing segment 541b from the pushing starting point 541d, driving the card-storing plate 12 to move along the supporting surface of the card-pushing seat 6 toward the card-lifting plate 3 until the front end of the mahjong tile overlaps the card-lifting plate 3;

[0131] Then, the secondary card pushing section 521bc reaches the card loading roller 535, and the card loading roller 535 rolls along the secondary card pushing section 521bc. The outer curved surface 521d squeezes the card loading roller 535, so that the card loading push rod 534 drives the card lifting rocker arm 532 to swing away from the shuffling barrel, and the card lifting roller 533 returns to the card lifting curved groove 531a from the top card avoidance groove 555. During this process, although the sloped card lifting plate 3 remains in the same position, the force exerted by the top card push rod 553 on the top card plate 551 disappears, and the top card plate 551 descends and releases the support for the mahjong tile. At this time, the top card roller 554 is still in the top card slot 522b; during this process, the card pushing roller 542 continues to roll along the pushing section 541b to the midpoint 541a of the track, pushing the mahjong tile completely onto the card lifting plate 3;

[0132] Then, the first-level lifting section 521ca reaches the card-loading roller 535, and the outer curved surface 521d continues to squeeze the card-loading roller 535, so that the card-loading push rod 534 continues to drive the card-lifting rocker arm 532 to swing toward the side away from the shuffling barrel, and the card-lifting roller 533 rolls from the groove bottom 531ab along the card-lifting curved groove 531a to the positioning groove 531aa, driving the card-lifting plate 3 to lift up until the side of the mahjong tile facing the card storage plate 12 is exposed on the mahjong machine panel; in this process, the top card roller 554 also rolls from the top card groove 522b along the card-lifting avoidance groove 552 to the groove bottom 552a, but the top card plate 551 remains in the same position; the card-pushing roller 542 rolls from the track midpoint 541a along the return section 541c to the return starting point 541e, preparing to return; in this process, the rolling trajectory of the card-pushing roller 542 coincides with the transmission cam 52 The rotation trajectory is concentrically arranged, so the card storage plate 12 also maintains its position unchanged, at its push card end point, to protect the mahjong tiles on the card lifting plate 3;

[0133] Subsequently, when the secondary lifting section 521cb reaches the card-loading roller 535, the outer curved surface 521d continues to squeeze the card-loading roller 535, so that the card-loading push rod 534 continues to drive the card-lifting rocker arm 532 to swing toward the side away from the shuffling barrel, and the card-lifting roller 533 continues to roll into the positioning notch 531aa of the card-lifting curved groove 531a, so that the card-lifting plate 3 is lifted up to be flush with the mahjong machine panel 100, and the mahjong tiles are lifted onto the table; in this process, the card-pushing roller 554 continues to roll to the bottom 552a of the card-lifting avoidance groove 552, waiting for the next card-pushing; and the card-pushing roller 542 rolls from the return starting point 541e along the return section 541c to the midpoint 541a of the track, driving the card storage plate 12 back to the initial position, waiting for the card pile from the card stacking seat 11.
