Description

TECHNICAL FIELD

[0001] The utility model belongs to mahjong machine technical field, specifically related to a mahjong machine and its card feeding mechanism. BACKGROUND

[0002] Each side of the eight-port mahjong machine has two card feeding ports, wherein the card feeding port close to the player is for feeding the dealing sequence, and the card feeding port close to the center of the mahjong machine is for feeding the picking sequence. In this way, the player does not need to manually pick the cards at the beginning of the game, and can directly take away the dealing sequence to start the game.

[0003] In order to be able to deliver two columns of card stacks to the tabletop, according to the number of card storage tracks, there are mainly two kinds of eight-port roller coaster type mahjong machines with different card feeding systems in the prior art.

[0004] The first kind is disclosed in Chinese patent application for invention with publication number CN110433481A, which discloses a mahjong machine. The card feeding system of the mahjong machine is provided with two card storage tracks arranged in an up-down manner, and also provided with a card stacking seat with a double-layer card receiving platform. The lower card storage track is used to deliver the picking sequence (from the lower card receiving platform of the card stacking seat), and the upper card storage track is used to deliver the dealing sequence (from the upper card receiving platform of the card stacking seat).

[0005] The disadvantage of this mahjong machine is that the picking sequence and the dealing sequence delivered by the same card feeding system are not in the same side of the mahjong machine, which leads to different card feeding directions of the two card feeding ports in the same side of the mahjong machine, and the user acceptance is low, and the audience is small.

[0006] The second kind is disclosed in Chinese patent application for invention with publication number CN118903805A, which discloses an eight-port mahjong machine. The card feeding system of the mahjong machine is provided with only one card storage track, but the card storage track has one card feeding port, one dealing sequence card outlet and one picking sequence card outlet. The channel connecting the card feeding port and the dealing sequence card outlet is located at a lower position and on the inner side, and the channel connecting the card feeding port and the picking sequence card outlet is located at a higher position and on the outer side. When three layers of card stacks enter the card storage track from the card feeding port, the upper two layers of card stacks will be sent to the picking sequence card outlet, and the lowest layer of mahjong cards will be sent to the dealing sequence card outlet.

[0007] Taking the three-layer card stack as an example, when the mahjong machine has the function of automatic card picking, in many game modes, the number of stacks M of the dealing sequence will be more than the number of stacks N of the picking sequence (more than Y cards), therefore, the sub-channel for delivering the dealing sequence is usually arranged at a lower position, and Y mahjong cards will be stored first, and then N three-layer card stacks will be stored; N+Y mahjong cards in the lowest layer form the dealing sequence, and the N three-layer card stacks in the upper layer form the picking sequence.

[0008] The mahjong machine has the following disadvantages: the number of mahjong tiles stored in the early stage of shuffling is small, which seriously affects the shuffling efficiency; and the mahjong tiles stored in the tile storage channel will become the tile dispensing sequence, so the mahjong machine can only be used for eight-player game mode and cannot be used for four-player game mode. SUMMARY

[0009] The mahjong machine and the tile feeding mechanism have the advantages of high tile shuffling efficiency and high compatibility with various game modes.

[0010] To achieve the above-mentioned object, the technical scheme of the mahjong machine is as follows:

[0011] The tile feeding mechanism of the mahjong machine comprises:

[0012] The stack pushing assembly is provided with an upper tile receiving platform and a lower tile receiving platform in the same vertical direction, the upper tile receiving platform is used for receiving the tile dispensing sequence, and the lower tile receiving platform is used for receiving and stacking the tile drawing sequence;

[0013] The tile storage assembly is provided with an arc-shaped tile storage channel, the tile storage channel has a tile inlet, a first tile outlet and a second tile outlet, the first tile outlet and the second tile outlet of the same tile storage channel are located at the same side of the mahjong machine; the main channel connected between the tile inlet and the second tile outlet is located at the lower outer side; and the first tile outlet is connected with the main channel through the sub-channel located at the higher inner side.

[0014] The tile pushing assembly is used for pushing the mahjong tiles in the tile storage channel from the tile inlet to the first tile outlet and the second tile outlet.

[0015] In the mahjong machine, only one tile storage channel is provided, the sub-channel for storing the tile dispensing sequence is located at a higher position, and the main channel for storing the tile drawing sequence is located at a lower position; when the mahjong tiles are stored in the tile storage channel, the mahjong tiles in the lower two layers become the tile drawing sequence, and the mahjong tiles in the uppermost layer or the upper two layers become the tile dispensing sequence; at this time, the tile drawing sequence is sent to the table top through the second tile outlet, and the tile dispensing sequence is sent to the table top through the first tile outlet; at this time, the mahjong machine is in the eight-player game mode, and the traditional eight-player game mode can be played; when the four-player game mode is needed, only two layers of tiles are stored in the tile storage channel; at this time, the traditional four-player game mode and the new eight-player game mode (the tile dispensing sequence and the tile drawing sequence are sent to the table top through the second tile outlet in turn) can be played in the four-player game mode, the compatibility with various game modes is high, and the audience is wide.

[0016] The utility model discloses a card storage channel is formed in the card storage device, and the card storage channel is divided into a main channel and a branch channel, and the main channel is connected with the branch channel, and the main channel is connected with the card storage channel, and the main channel is connected with the card storage channel.

[0017] As preferred, in the above-mentioned card feeding mechanism, the card storage assembly comprises:

[0018] The card storage device, the card storage channel is formed in the card storage device;

[0019] The card distributor is arranged above the card storage device and is used for guiding the card feeding sequence into the branch channel.

[0020] Under the guidance of the card distributor, the front end of the card feeding sequence will enter the branch channel as long as the up-pushing assembly starts to push the cards, or when the mahjong cards of the card feeding sequence are separately stored in the later stage of the shuffling, the front end of the card feeding sequence will be pushed into the branch channel.

[0021] However, due to the different number of mahjong cards used in different regions and different playing methods, in order to facilitate the card feeding sequence to enter the branch channel, as preferred, a patch is detachably arranged in the card storage channel, and the patch has a supporting eave which protrudes from the branch channel to the main channel and extends to the card inlet.

[0022] The protruding width of the supporting eave gradually increases from the end close to the card inlet to the end close to the branch channel.

[0023] In the above-mentioned card feeding mechanism, the up-pushing assembly comprises a card feeding push rod, and the card feeding push rod comprises a rod body and a fixed end and a free end at both ends of the rod body, the fixed end is connected with the up-pushing motor, and the free end is provided with a card feeding push head.

[0024] The card feeding push head is used for pushing the cards in the main channel, and the rod body is used for pushing the cards in the branch channel.

[0025] In the utility model, only one card feeding push head is needed, and the entire three or four layers of card piers are pushed forward by the card feeding push head at the position close to the card inlet; as the card feeding push rod comes to the connection between the branch channel and the main channel, the card feeding push head continues to push the card feeding sequence in the main channel, and the card feeding sequence at the higher position on the inner side is directly pushed by the rod body, so that the structure is simple and the respective card feeding can be realized.

[0026] As preferred, in the above-mentioned card feeding mechanism, the side of the rod body facing the first card outlet is formed with an inclined surface used for guiding the card feeding sequence to move to the first card outlet, and the inclined surface is arranged at an obtuse angle with the extension direction of the rod body.

[0027] Compared with the plane which is flush with the push head, the inclined plane is beneficial to make the dealing sequence more smoothly and quickly enter the sub-channels and move to the first dealing opening.

[0028] As a preferred, the dealing mechanism further comprises a card lifting assembly, the card lifting assembly comprises a first card lifting plate and a second card lifting plate, the first card lifting plate has eight-machine working positions which are synchronously lifted with the second card lifting plate and four-machine working positions which are kept horizontal when the second card lifting plate is lowered.

[0029] At the eight-machine working positions, the first card lifting plate and the second card lifting plate are both lowered to receive cards respectively; while at the four-machine working positions, only the second card lifting plate is lowered, and the dealing sequence receiving plate is not lowered. Of course, even if there is no dealing sequence in the sub-channels, the first card lifting plate and the second card lifting plate are synchronously lowered in the four-machine game, and only the first card lifting plate cannot receive cards.

[0030] In order to facilitate the first card lifting plate to switch between the eight-machine working positions and the four-machine working positions, as a preferred, a magnetic attraction unit is arranged between the second card lifting plate and the first card lifting plate to make them synchronously lift.

[0031] The card lifting assembly further comprises a card lifting mode switching unit, the card lifting mode switching unit has a first working position which prevents the first card lifting plate from being lowered when there is no dealing sequence in the card storage channel, and a second working position which removes the prevention of the first card lifting plate when there is a dealing sequence in the card storage channel.

[0032] In this way, in the four-machine game, the first card lifting plate is blocked by the card lifting mode switching unit from below, so the magnetic attraction unit cannot work, and the second card lifting plate cannot lower with the first card lifting plate; in the eight-machine game, the card lifting mode switching unit only needs to change position to not block the first card lifting plate from being lowered.

[0033] As a further preferred, in the above dealing mechanism, the card lifting mode switching unit comprises an arm, the arm comprises a hinge point and a long arm end and a short arm end on both sides of the hinge point, the long arm end is provided with a supporting piece for supporting the first card lifting plate, and the short arm end is movably connected with a lever;

[0034] The lever is slidably installed on the mahjong machine and connected with a trigger module, the trigger module is used for sensing whether there is a dealing sequence in the card storage channel and controlling the lever according to the sensing result.

[0035] The top supporting piece is kept under the first lifting plate in normal state, which prevents the first lifting plate from descending and ensures that the first lifting plate will not collapse when being pressed from above.

[0036] Preferably, in the card feeding mechanism, the card stacking assembly comprises a card stacking base, and the upper card supporting platform and the lower card supporting platform are arranged on the card stacking base.

[0037] The card stacking base is further provided with an upper blocking plate and a lower blocking plate, and the upper blocking plate and the lower blocking plate each form an L-shaped card supporting space with the upper card supporting platform and the lower card supporting platform.

[0038] The utility model further provides a mahjong machine, the mahjong machine includes the frame, each side of the frame is equipped with the card feeding mechanism.

[0039] Compared with the prior art, the technical effects of the utility model are embodied in that:

[0040] (1) In the utility model, only one card storage channel is arranged, and the sub-channel for storing the card feeding sequence is arranged at a high position, and the main channel for storing the card drawing sequence is arranged at a low position, so that when the mahjong tiles are stored in the card storage channel, the mahjong tiles in the lower two layers become the card drawing sequence, and the mahjong tiles in the uppermost layer or the upper two layers become the card feeding sequence, at this time, the card drawing sequence and the card feeding sequence are sent to the table top through different lifting plates, at this time, the mahjong machine is an eight-port machine mode, and the traditional eight-port machine play can be performed; when it is required to be changed into a four-port machine mode, only two layers of tile stacks need to be stored in the card storage channel, at this time, the traditional four-port machine play and the new eight-port machine play can be performed in the four-port machine mode, the compatibility of various playing modes is high, and the audience is wide.

[0041] (2) In the utility model, the upper card supporting platform and the lower card supporting platform are used to support the cards in the early stage of shuffling, and three or four layers of tile stacks are stored in the card storage channel, the tile stacks contain the card feeding sequence and the card drawing sequence, when the number of the stored tile stacks is the same as the number of the card drawing sequence but smaller than the number of the card feeding sequence, only the upper card supporting platform is used to support the cards in the late stage of shuffling, and the remaining card feeding sequence is stored above the card drawing sequence (the stored card will be pushed forward by the later card), and the shuffling efficiency is greatly improved.

[0042] (3) The upper pushing assembly only needs one card pushing head, and the whole three or four layers of card piles are pushed forward by the card pushing head at the position close to the card inlet; with the card pushing rod reaching the connection between the branch channel and the main channel, the card pushing head continues to push the card sequence in the main channel, and the card sequence at the higher position on the inner side is directly pushed by the rod body, so that the structure is simple and the respective card feeding can be realized.

[0043] (4) In the eight-port machine play mode, the first card lifting plate is driven by the second card lifting plate to synchronously lift and descend, in the four-port machine play mode, the first card lifting plate can still synchronously lift and descend with the card sequence, or can not descend, and the connection between the first card lifting plate and the second card lifting plate is released by the card lifting mode switching unit from the bottom.

[0056] The technical scheme of the utility model will be described in further detail below in combination with the drawings and embodiments. Embodiment 1

[0057] As shown in Figure 1 , Figure 2 and Figure 3 , the mahjong machine tile feeding mechanism of the embodiment comprises a tile stacking and pushing assembly 1, a tile storage assembly 2, a tile pushing assembly 3 and a tile lifting assembly 4, wherein the tile stacking and pushing assembly 1 is used to stack the mahjong tiles picked up from the tile washing tray into a tile stack and push the tile stack into the tile storage assembly 2, the tile storage assembly 2 is used to store the tile stack, and when the number of the stored tile stack reaches a preset value, the tile pushing assembly 3 pushes all the mahjong tiles onto the tile lifting assembly 4, and the tile lifting assembly 4 lifts the mahjong tiles to the tabletop.

[0058] As shown in Figure 4 and Figure 5 , in combination with Figure 1 , it can be seen that the tile stacking and pushing assembly 1 of the embodiment comprises a head 11, the head 11 is connected with a tile stacking and pushing motor and rotates under the drive of the tile stacking and pushing motor; a tile pushing rod 12 is horizontally arranged above the head 11, one end of the tile pushing rod 12 is hingedly connected with a tile storage device 21, and the other end is fixedly installed with a tile pushing head 13; an eccentric tile pushing bearing 14 is fixedly installed at the top end of the head 11, and a tile pushing curved groove 121 is formed on the tile pushing rod 12, the tile pushing bearing 14 is accommodated in the tile pushing curved groove 121, and when the head 11 rotates, the tile pushing rod 12 swings under the drive of the tile pushing bearing 14, so that the tile pushing head 13 can perform the tile pushing operation.

[0059] In the embodiment, a tile stacking seat 15 is installed on the tile storage device 21 in a lifting manner, the tile stacking seat 15 is formed with an L-shaped upper layer tile bearing space composed of an upper tile blocking plate 151 and an upper tile bearing platform 152, and an L-shaped lower layer tile bearing space composed of a lower tile blocking plate 153 and a lower tile bearing platform 154.

[0060] In the eight-port machine mode, the L-shaped upper layer tile bearing space is used to bear the tile feeding sequence (which can be single-layer or double-layer), the drawings of the embodiment are schematically shown in the size suitable for the single-layer tile feeding sequence, and the L-shaped lower layer space is used to stack the tile picking sequence (which is usually double-layer). Correspondingly, the tile pushing head 13 of the embodiment also has an upper tile pushing part 131 and a lower tile pushing part 132 for pushing the tiles in the L-shaped upper layer tile bearing space and the L-shaped lower layer tile bearing space, respectively.

[0061] It should be noted that in different gameplay variations, the length of the dealing sequence may be longer than the length of the drawing sequence, or it may be the same length. When the two lengths are the same, the stacking stand 15 only needs to repeatedly stack three or four layers of tiles. In this case, there is no need to set up a double-layer tile-holding space on the stacking stand 15; only the lower tile-holding platform 154 is required. However, when the dealing sequence is longer, it is necessary to store additional mahjong tiles above the drawing sequence to complete the dealing sequence. In this case, a double-layer tile-holding space is required on the stacking stand 15.

[0062] like Figure 4 and Figure 5 As shown, a card-bearing curved groove is also formed on the outer peripheral wall of the machine head 11. A card-bearing bearing 155 inserted into the card-bearing curved groove is fixedly installed on the card-bearing seat 15. When the machine head 11 rotates, the card-bearing bearing 155 rolls in the card-bearing curved groove, thereby driving the card-bearing seat 15 to rise and fall according to the program to stack cards.

[0063] Specifically, the card-bearing curved groove of this embodiment includes a long horizontal section 111, a downward curved section 112, and an upward curved section 113 arranged sequentially and connected end to end. When the card-stacking bearing 155 rolls in the long horizontal section 111, the card-stacking seat 15 keeps its position unchanged. When the card-stacking seat 15 rolls in the downward curved section 112, the card-stacking seat 15 descends so that the mahjong tiles can be stacked sequentially on the lower card-bearing platform 154 and the upper card-bearing platform 152. When the card-stacking bearing 155 rolls in the upward curved section 113, the card-stacking seat 15 rises to raise the tile stack to the initial height so that the card-pushing head 13 can perform the card-pushing action.

[0064] Because the stacking stand 15 in this embodiment is provided with two layers of holding platforms, the mahjong tiles are first stored in the lower holding platform 154 and then in the upper holding platform 152. That is, the stacking stand 15 has at least three holding heights: at the first height, the lower holding platform 154 stores the first mahjong tile; when it descends to the second height, the lower holding platform 154 stores the second mahjong tile; when it descends to the third height, the upper holding platform 152 stores a mahjong tile.

[0065] To prevent the upper holding platform 152 from affecting the storage of the second mahjong tile on the lower holding platform 154, the descending curve segment 112 can be divided into three segments: a gently descending curve segment 112a, a short horizontal segment 112b, and a steeply descending curve segment 112c. When the stacking bearing 155 rolls within the gently descending curve segment 112a and the short horizontal segment 112b, the stacking base 15 descends relatively slowly from the first height to the second height and pauses there briefly. After the second mahjong tile is stored on the lower holding platform 154, the stacking bearing 155 rolls into the steeply descending curve segment 112c, and the stacking base 15 descends relatively quickly from the second height to the third height.

[0066] like Figure 1、 Figure 2 and Figure 3 As shown in Figs. 1, 2 and 3, the mahjong tile storage assembly 2 of the present embodiment comprises a mahjong tile storage device 21, which is concavely provided with a mahjong tile storage channel having a tile inlet 211, a first tile outlet 212 and a second tile outlet 213, wherein the tile stack seat 15 is mounted at the tile inlet 211.

[0067] As shown in Figs. 1, 2 and 3, the mahjong tile storage assembly 2 of the present embodiment comprises a mahjong tile storage device 21, which is concavely provided with a mahjong tile storage channel having a tile inlet 211, a first tile outlet 212 and a second tile outlet 213, wherein the tile stack seat 15 is mounted at the tile inlet 211. Figure 3 As shown in Figs. 1, 2 and 3, the mahjong tile storage assembly 2 of the present embodiment comprises a mahjong tile storage device 21, which is concavely provided with a mahjong tile storage channel having a tile inlet 211, a first tile outlet 212 and a second tile outlet 213, wherein the tile stack seat 15 is mounted at the tile inlet 211.

[0068] At the tile inlet 211, the mahjong tiles stored in the main channel 214 are three-layer tile stacks or four-layer tile stacks (in the mode of an eight-tile machine), and as the number of the tile stacks increases, when the storage position of the tile stacks reaches the connection between the sub-channel 215 and the main channel 214, the uppermost one or two layers of mahjong tiles enter the sub-channel 215 and become the tile dispensing sequence, while the lowermost two layers of tile stacks remain in the main channel 214 and become the tile drawing sequence.

[0069] The separation of the tile dispensing sequence and the tile drawing sequence is guided by the tile separator 22. As shown in Figs. 1, 2 and 3, Figure 1 、 Figure 2 and Figure 3 As shown in Figs. 1, 2 and 3, the mahjong tile storage assembly 2 of the present embodiment comprises a mahjong tile storage device 21, which is concavely provided with a mahjong tile storage channel having a tile inlet 211, a first tile outlet 212 and a second tile outlet 213, wherein the tile stack seat 15 is mounted at the tile inlet 211.

[0070] In different game modes, the number of mahjong tiles stored in the mahjong tile storage channel and the length of the tile dispensing sequence vary greatly; in order to enable the sub-channel 215 to quickly connect to the tile dispensing sequence in any game mode, the tile separator 22 is provided with an arc-shaped guide surface 221. Figure 2 Figure 3 ​As shown, the sub-channel 215 also has an extension section 216 extending rearward from the communication part of the sub-channel 215 with the main channel 214 to the direction of the card inlet 211; in order not to hinder the work of the card pushing head 33 (this is the case where the card pushing head 33 is higher to push the dealing sequence and the picking sequence simultaneously at the end of the card inlet, if two independent card pushing heads are used to push the dealing sequence and the picking sequence respectively, then there is no requirement for the width of the extension section 216 and the supporting eave 231 below), the width of the extension section 216 is smaller than the width of the main channel 214, and the closer to the card inlet 211, the smaller the width of the extension section 216.

[0071] In addition to setting the extension section 216, the purpose of extending the sub-channel 215 can also be achieved by installing a patch 23 in the sub-channel 215. As shown in Figure 1 and Figure 3 The patch 23 has a supporting eave 231 protruding from the sub-channel 215 to the main channel 214 and extending to the card inlet 211; similarly, the protruding width of the supporting eave 231 is gradually widened from the end close to the card inlet 211 to the end close to the sub-channel 215.

[0072] The extension section 216 and the supporting eave 231 can be set simultaneously or separately, both of which can achieve the intended purpose. In this way, under the guidance of the card distributor 22, as soon as the up-pushing assembly 3 starts to push the cards, the front end of the dealing sequence will enter the sub-channel 215, or when the mahjong tiles of the dealing sequence are separately stored in the later stage of shuffling, the front end of the dealing sequence will be pushed into the sub-channel 215.

[0073] As shown in Figure 6 and Figure 7 The up-pushing assembly 3 of the present embodiment includes a card pushing rod 31, which includes a rod body 311 and a fixed end 312 and a free end 313 at both ends of the rod body 311; wherein the fixed end 312 is disc-shaped and rotationally connected with the tile storage device 21, the bottom of the fixed end 312 is provided with a transmission gear ring 314, and the tile storage device 21 is also rotationally connected with a driving gear 32 engaged with the transmission gear ring 314, and the driving gear 32 is connected with an up-pushing motor. In other cases, the fixed end 312 can also be directly connected with the up-pushing motor (i.e. without the driving gear 32).

[0074] As can be seen from Figure 6 and Figure 7 The free end 313 is provided with a card pushing head 33, which simultaneously pushes the dealing sequence and the picking sequence in the main channel 214 before the dealing sequence and the picking sequence are completely separated; and after the dealing sequence and the picking sequence are completely separated, the card pushing head 33 continues to push the picking sequence in the main channel 214, and the rod body 311 crossing the sub-channel 215 starts to push the dealing sequence.

[0075] In order to improve the efficiency of pushing the tiles, the side of the rod body 311 towards the first tile outlet 212 is provided with an inclined surface 315, which is arranged at an obtuse angle with the extension direction of the rod body 311; when the rod body 311 pushes the tile sequence, the tile sequence can more smoothly and quickly enter the distribution channel 215 and move towards the first tile outlet 212 along the inclined surface 315.

[0076] As shown in Figure 8 and Figure 9 The tile lifting assembly 4 of the present embodiment includes a first tile lifting plate 41 and a second tile lifting plate 42 hinged to the mahjong machine, wherein the second tile lifting plate 42 is connected to a tile lifting driving unit 43, and the second tile lifting plates 42 at the four corners of the mahjong machine are all driven by the same tile lifting driving unit 43 (this linkage mode has been proposed in the previous patent documents of the patentee, and the present embodiment will not be described in detail; obviously, each second tile lifting plate 42 can also be driven by an independent tile lifting driving unit) ; and the first tile lifting plate 41 is connected through a magnetic attraction unit 44 arranged at the bottom of the first tile lifting plate 41 and the second tile lifting plate 42, so that the second tile lifting plate 42 can drive the first tile lifting plate 41 in the same corner to lift synchronously, so that the eight-port mahjong game can be played.

[0077] However, in the present embodiment, the first tile lifting plate 41 is not always linked with the second tile lifting plate 42, and when needed, it can be disconnected from the second tile lifting plate 42 by means of a tile lifting mode switching unit 45.

[0078] As shown in Figure 10 , in combination with Figure 1 It can be seen that the tile lifting mode switching unit 45 includes a base 451 detachably mounted on the tile storage device 21, a lever 452 slidingly mounted on the base 451, the head end of the lever 452 facing the tile storage channel and having a sensing module 453 extending into the tile storage channel, the sensing module 453 being used to sense whether the tile sequence to be sent to the first tile outlet is stored in the tile storage channel. The tail end of the lever 452 is movably connected with a swing arm 454, the swing arm 454 is movably connected with the tile storage device 21 through a hinge point 454a, the swing arm 454 is divided into a long arm end 454b and a short arm end 454c by the hinge point 454a, the lever 452 is hingedly connected with the short arm end 454c, and a supporting piece 455 can be installed on the long arm end 454b as needed (in the case where the long arm end 454b is far away from the first tile lifting plate 41, if the distance between them is very close, the supporting piece 455 need not be provided).

[0079] The top support 455 is kept under the first lifting plate 41 in normal state, which prevents the first lifting plate 41 from descending and ensures that the first lifting plate 41 will not collapse when pressed from above. When the dispensing sequence to be sent to the first dispensing port is stored in the storage channel, the dispensing sequence will press the sensing module 453, causing the lever 452 to slide backward and the swing arm 454 to swing counterclockwise, and the top support 455 will also move to the side below the first lifting plate 41, so that the first lifting plate 41 can freely descend.

[0080] In addition to directly setting the sensing module 453 on the lever 452 and using the dispensing sequence to press the lever 452 to slide, a sensor can also be used to monitor the presence or absence of the dispensing sequence, and then the sliding of the lever 452 can be controlled by a linear actuator according to the monitoring result of the sensor.

[0081] When the first lifting plate 41 is stopped by the top support 455, only the second lifting plate 42 can freely ascend and descend, and the mahjong machine is equivalent to a four-port machine, which can play traditional four-port games or two new eight-port games. The two new eight-port games have been disclosed in the Chinese Utility Model Patent Application No. CN118615691A, and this embodiment will not be described here.

[0082] Obviously, even if the first lifting plate 41 is not stopped by the top support 455 and freely descends, but the storage channel does not store the dispensing sequence, the mahjong machine is essentially a four-port machine, which can also implement traditional four-port games and new eight-port games in the four-port mode.

[0083] In this embodiment, the sensing module 453 is close to the card inlet 211 of the storage channel, which ensures that the sensing module 453 can still sense the dispensing sequence after the dispensing sequence is completely stored in the sub-channel 215, so that the top support 455 always avoids the descending path of the first lifting plate 41 before the first lifting plate 41 descends. When the dispensing sequence no longer presses the sensing module 453, the first lifting plate 41 has descended, and even if the swing arm 454 swings back, the top support 455 is only on the side of the first lifting plate 41, and because the pressing force of the top support 455 is small, it basically does not affect the ascending of the first lifting plate 41.

[0084] In this embodiment, the top support 455 can be fixedly installed on the swing arm 454, at this time, the pushing path of the card pushing rod 31 is: running from the card inlet 211 to the card outlet and returning to the card inlet 211 along the original path. But the card pushing rod 31 also has another pushing path, that is, running from the card inlet 211 to the card outlet and then continuing to run back to the card inlet 211 (rotating 360°); under this pushing path, the top support 455 is not suitable for fixed setting because it is in the running path of the card pushing rod 31. At this time, the top support 455 can be movably installed on the swing arm 454 through the elastic member, under the action of the elastic member, the top support 455 is normally upright on the swing arm 454, but when the top support 455 is pressed by the card pushing rod 31, it will be turned down to avoid the card pushing rod 31, and after the card pushing rod 31 passes, the top support 455 will return to the original position under the action of the elastic member.

[0085] In order to facilitate the passing of the card pushing rod 31, the embodiment also sets a wedge surface 455a on the top support 455, which faces the coming path of the card pushing rod 31.

[0086] When the eight-port machine mode is played, the working principle of the card feeding mechanism of the embodiment is as follows:

[0087] The stacking motor is started, the machine head 11 rotates with the output shaft of the stacking motor, at this time, the stacking bearing 155 rolls in the long horizontal section 111 of the card bearing curve groove, so that the stacking seat 15 stays at the first height, at this time, the lower card bearing platform 154 is flush with the card inlet 211 of the card storage channel; after the lower card bearing platform 154 receives the first mahjong card, the stacking bearing 155 successively rolls into the slow descending curve section 112a and the short horizontal section 112b, so that the stacking seat 15 descends to the second height and pauses for a while at the second height; after the lower card bearing platform 154 receives the second mahjong card, the stacking bearing 155 rolls into the steep descending curve section 112c, so that the stacking seat 15 descends to the third height, at this time, the upper card bearing platform 152 is flush with the card inlet 211 of the card storage channel; after the upper card bearing platform 152 receives the mahjong card, the stacking bearing 155 rolls into the upward curve section 113, so that the stacking seat 15 rises from the third height to the first height; at this time, the card pushing head 13 is also driven by the card pushing bearing 14 to wait at the card inlet 211, when the stacking seat 15 returns to the first height, the card pushing rod 12 also starts to swing towards the card storage channel, and the card pushing head 13 pushes the mahjong cards on the upper card bearing platform 152 and the lower card bearing platform 154 into the card storage channel by the upper card pushing part 131 and the lower card pushing part 132 at the same time;

[0088] After the above-mentioned process is repeated, when the number of the tiles stored in the storage channel is M, which is equal to the number of the tiles in the tile stack of the draw sequence, and if all the draw sequence and the draw sequence have been obtained (i.e., the length of the draw sequence is equal to the length of the draw sequence), the tile pushing assembly starts to push the tiles. Under the guidance of the tile distributor 22, the draw sequence enters the distribution channel 215, waits for the tiles to be raised at the first tile outlet 212, and then is raised to the tabletop by the first tile raising plate 41. The draw sequence advances along the main channel 214, waits for the tiles to be raised at the second tile outlet 213, and then is raised to the tabletop by the second tile raising plate 42.

[0089] If the number of tiles in the draw sequence is still insufficient at this time (i.e., the length of the draw sequence is greater than the length of the draw sequence), the stacking and pushing motor continues to work, and the tile stacking seat 15 continues to descend. Before the tile stacking seat 15 descends to the third height, the tile conveying motor (used to send the tiles picked up by the tile suction wheel to the tile stacking seat 15) is controlled to stop sending tiles to the lower tile supporting platform 154 of the tile stacking seat. After the tile stacking seat 15 descends to the third height, the upper tile supporting platform 152 receives the tiles, and then returns to the first height according to the program. The tile pushing part 131 pushes the second tile stack into the storage channel, and the second tile stack is above the lower tile stack (usually two layers) of the first tile stack. The upper tile stack (one or two layers) moves relative to the lower tile stack due to the pushing of the second tile stack. At this time, the front end of the upper tile stack has at least reached the supporting eaves.

[0090] After N tiles are stored again, M+N is the number of tiles in the draw sequence. At this time, the tile pushing motor is started, and the tile pushing rod 31 rotates around its fixed end 312, so that the tile pushing head 33 enters the storage channel from the tile inlet 211 and starts to push the tiles. At the end close to the tile inlet 211, the tile pushing head 33 simultaneously pushes all the three or four layer tile stacks forward. When the draw sequence enters the distribution channel 215, the tile pushing head 33 continues to stay in the main channel 214 to push the draw sequence to the second tile outlet 213, and the draw sequence is pushed to the first tile outlet 212 by the rod body 311 which sweeps through the distribution channel 215.

[0091] Since the sensing module 453 is partially protruding in the storage channel, when the draw sequence to be sent to the first tile outlet is stored in the storage channel, the sensing module 453 is squeezed by the draw sequence, causing the lever 452 to slide backward, in turn driving the swing arm 454 to swing counterclockwise, and the supporting member 455 is also transferred to the lower side of the first tile raising plate 41. When the tile raising driving unit 43 drives the second tile raising plate 42 to descend, the first tile raising plate 41 also descends under the drive of the magnetic unit. At this time, the tile pushing rod 31 continues to operate, and the rod body 311 and the tile pushing head 33 push the draw sequence and the draw sequence to the corresponding tile raising plates, respectively.

[0092] When the pressure applied to the sensing module 453 by the card dealing sequence disappears, the top support 455 tends to return to its original position. However, before the first card lifting plate 41 rises, the top support 455 can only rest against the side of the first card lifting plate 41. However, the pressure of the top support 455 is small, so it will not affect it even when the first card lifting plate 41 rises.

[0093] After the first lifting plate 41 and the second lifting plate 42 rise, the top support 455 can return to its original position. At this time, the top support 455 supports the first lifting plate 41 from below, which prevents the free end 313 of the first lifting plate 41 from collapsing. Meanwhile, the plate-raising push rod 31 continues to run in order to return to the plate inlet 211. When the plate-raising push rod 31 runs to the top support 455, the plate-raising push rod 31 applies a reaction force against the elastic element to the top support 455, causing the top support 455 to flip backward. After the plate-raising push rod 31 passes, the top support 455 will flip upward under the action of the elastic element and return to its original position.

[0094] When playing four-player or eight-player games in four-player mode, the working principle of the card-issuing mechanism in this embodiment is as follows:

[0095] In the stacking stand 15, only the lower holding platform 154 accepts tiles, while the upper holding platform 152 does not accept tiles (when the upper holding platform 152 descends to a position where it can accept tiles, the mahjong machine will not feed mahjong tiles to the stacking stand). Therefore, the storage channel stores double-layered tile stacks. These tile stacks cannot enter the sub-channel 215, so they are all sent to the second tile outlet 213 via the main channel 214.

[0096] In this situation, no card-dealing sequence is stored in the card storage channel, so the sensing module 453 will not be triggered, and the top support 455 remains below the first card-lifting plate 41 to prevent the first card-lifting plate 41 from descending.

[0097] In this situation, the double-layered deck can be delivered to the table via the second lifting plate 42 in three ways:

[0098] The first type is where all cards are dealt to the table at once, which is the traditional four-player game. Players draw cards from the table to determine the dealing sequence.

[0099] The second type (such as) Figure 12 The second card-raising plate 42 rises and falls once, first sending the card-dealing sequence to the table. After the sensor 6 detects that the card-dealing sequence has been taken away, the remaining card-drawing sequence is then sent to the table.

[0100] The third type involves the card-adding pusher 33 running between the card-dealing sequence and the card-drawing sequence. The second card-lifting plate 42 first rises and falls once to send the card-dealing sequence to the table. Then, the card-adding pusher 33 returns to the card-entry port 211 and runs to the back of the card-drawing sequence. The second card-lifting plate 42 then rises and falls once more to send the card-drawing sequence to the table.

[0101] It can be seen that the second and third are new eight-player game play in four-player mode, at this time the dealing sequence is in the main channel 214, which is different from the position of the dealing sequence in the eight-player mode. Embodiment 2
