Description

Technical Field

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

[0002] Fully automatic mahjong machines are becoming more and more popular because they can automatically stack the tiles. When stacking the tiles, the tiles need to be stacked into piles of two or three tiles. In order for the second and third tiles to be stacked on the first tile, the tray is usually located below the outlet of the card delivery device. The tiles fall from the delivery channel at high speed. If effective measures are not taken, the tiles will be stacked.

[0003] In order to solve the above problems, technicians have developed many improvement schemes for the mahjong machine stacking device.

[0004] For example, the Chinese invention patent application with publication number CN107281748A discloses a mahjong machine and a stacking device and a method for stacking mahjong tiles. When stacking three mahjong tiles, the method for stacking mahjong tiles includes the following steps:

[0005] (1) the card receiving platform stays at a first height, which is lower than the height of the card outlet of the card delivery device, and the card receiving platform receives the first mahjong tile delivered from the card delivery device;

[0006] (2) After detecting that the first mahjong tile is in place, the card receiving platform descends and stays at a second height. At this time, the top surface of the first mahjong tile is lower than the card outlet of the card delivery device. The card receiving platform receives the second mahjong tile delivered from the card delivery channel, and the second mahjong tile is stacked on the first mahjong tile;

[0007] (3) After detecting that the second mahjong tile is in place, the card receiving platform descends again and stays at the third height. At this time, the top surface of the second mahjong tile is lower than the card outlet of the card delivery device. The card receiving platform receives the third mahjong tile delivered from the card delivery channel, and the third mahjong tile is stacked on the second mahjong tile;

[0008] (4) After detecting that the third mahjong tile is in place, the pusher pushes the three stacked mahjong tiles onto the storage board.

[0009] The disadvantage of this stacking method is that the card receiving platform has three working heights, which requires the stacking device to have a driving mechanism that can drive the card receiving platform up and down, and this driving mechanism makes the structure of the stacking device very complicated.

[0010] For another example, Chinese utility model patent with publication number CN211132966U discloses an inclined plate stacking mechanism, which includes a card receiving bracket, a top surface of which is provided with a groove located below a card outlet of a card feeding device, at which a card stacking inclined plate is rotatably connected to the card receiving bracket, and a torsion spring is connected to the card stacking inclined plate so that its free end has an upward flipping tendency, and under the action of the torsion spring, the card stacking inclined plate is inclined upward from a fixed end close to the card outlet of the card feeding device to a free end away from the card outlet of the card feeding device; when the mahjong cards fall onto the card stacking inclined plate, the free end of the card stacking inclined plate drops under the pressure of the mahjong cards and is in a horizontal state, and the card pushing mechanism pushes the mahjong cards in a horizontal state onto the card storage plate.

[0011] The above-mentioned inclined plate card pushing mechanism has the following disadvantages: (1) when the mahjong tiles fall from the card outlet of the card feeding device, they are inclined with the head end at the bottom and the tail end at the top, while when the stacking inclined plate is waiting to receive the tiles, it is inclined with the fixed end at the bottom (close to the tail end of the tiles) and the free end at the top (close to the head end of the tiles). When the mahjong tiles fall onto the stacking inclined plate, the distance between the head end of the tiles and the free end of the stacking inclined plate is short, while the height difference between the tail end of the tiles and the free end of the stacking inclined plate is high. (2) When a mahjong tile falls onto the stacking inclined board, the free end of the stacking inclined board falls and makes the stacking inclined board horizontal. When stacking the second or more mahjong tiles, if there is a height difference between the card outlet of the card feeding device and the first mahjong tile, the second mahjong tile will inevitably fall. Summary of the invention

[0012] The invention aims to provide a mahjong machine stacking device, which has a simple structure and can effectively prevent cards from being planted.

[0013] To achieve the above-mentioned object of the invention, the technical solution of the present invention is as follows:

[0014] A card stacking device for a mahjong machine comprises a card stacking seat located at a card outlet of a card feeding mechanism, a card receiving platform formed on the card stacking seat, the card receiving platform being arranged downwardly inclined from a side close to the card feeding mechanism to a side away from the card feeding mechanism, a card stacking guardrail being formed on the side of the card receiving platform away from the card feeding mechanism, and the card receiving platform and the card stacking guardrail together enclose a card stacking space.

[0015] The present invention arranges the card receiving platform to be tilted downward from the side close to the card feeding mechanism to the side far away from the card feeding mechanism, that is, the tilting direction of the card receiving platform is basically consistent with the diving posture of the mahjong tiles when they fall. Therefore, when the mahjong tiles fall onto the card receiving platform, the entire bottom surface of the mahjong tiles can contact with the card receiving platform at the same time, or the bottom surface of the mahjong tiles can contact with the card receiving platform at a small angle, and then slide along the card receiving platform for a certain distance before abutting against the card stacking guardrail; the second mahjong tile is also stacked in the same way, so that the card planting phenomenon can be completely eliminated under the premise that the card receiving platform remains static; and the overall structure of the card stacking seat is simple, no redundant driving structure is required, and the manufacturing cost is low.

[0016] The inclination angle of the card receiving platform, that is, the angle between the card receiving platform and the horizontal plane, can be set between 5° and 45°, preferably between 10° and 30°; it is preferably close to the inclination angle when the mahjong tiles fall. Obviously, the inclination angle when the mahjong tiles fall onto the card receiving platform is also related to the falling height of the mahjong tiles, that is, the height difference between the card receiving platform and the card outlet of the card delivery channel.

[0017] In the above-mentioned mahjong machine stacking device, the stacking seat is fixed or lifted at the card output end of the card delivery mechanism. When the stack of cards to be stacked is two layers, the stacking seat can be fixedly installed at the card output end of the card delivery channel, or can be lifted at the card output end of the card delivery channel. In actual situations, it can be fixed at the card output end of the card delivery channel; when the stack of cards is three layers or more, it is preferred to lift the stacking seat at the card output end of the card delivery channel, or the inclination angle of the card receiving platform can be appropriately increased to adapt to the posture of the mahjong cards when they fall.

[0018] The above-mentioned mahjong machine stacking device also includes a stacking and pushing mechanism and a card storage board respectively arranged on opposite sides of the card receiving platform, and the stacking and pushing mechanism is used to push the card pile on the card receiving platform to the card storage board. Since the card receiving platform is inclined, in order to facilitate the transfer of mahjong cards from the stacking seat to the card storage board, the card storage board of the present invention also has the same inclined state as the stacking seat.

[0019] That is, in the above-mentioned mahjong machine stacking device, the card storage plate includes a card storage platform on the same plane as the card receiving platform, and a card storage guardrail on the same plane as the stacking guardrail, and the card storage guardrail is fixedly arranged on one side of the card storage platform to prevent mahjong cards from sliding off the card storage platform.

[0020] In the above-mentioned mahjong machine stacking device, the card storage plate has a card storage position located on the side of the card receiving platform to receive mahjong tiles, and a card delivery position moving toward the shuffling barrel to deliver the mahjong tiles;

[0021] The stacking card guardrail has a stacking position located on the side of the card receiving platform to assist in stacking cards, and a retracting position that moves synchronously with the card storage board to compress the stacking card space to retract the periphery of the mahjong machine; or, the stacking card seat and the card storage board are independent of each other.

[0022] The present invention arranges the card storage board to be able to move relative to the card raising board, that is, when receiving mahjong tiles, the card storage board remains at the side of the card receiving platform unchanged; when the reception is completed, it moves toward the shuffling barrel so as to send the mahjong tiles to the card raising board; the side of the card storage platform opposite to the card storage guardrail is the card discharging side.

[0023] When the card storage board is moved toward the card raising board, the area of ​​the mahjong machine has the opportunity to be reduced. When the mahjong machine needs to be packed and transferred, a smaller packaging box can be used to pack the mahjong machine, thereby saving transportation costs 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.

[0024] Since the stacking seat and the card storage board are on the same plane, if only the card storage board has the retractable displacement but the stacking seat does not, the periphery of the mahjong machine is still difficult to retract. In order to retract the periphery of the mahjong machine as a whole, the present invention sets the stacking space to be deformable, and the stacking guardrail can move synchronously with the card storage board.

[0025] However, since the card stacking guardrail is opposite to the card feeding mechanism, when the card stacking guardrail and the card storage guardrail move synchronously, the card stacking guardrail will gradually approach the card feeding mechanism. If no measures are taken, the card stacking guardrail will not only hit the card feeding mechanism, but also affect the normal card feeding of the card storage board.

[0026] In order to solve the above problem, in the above-mentioned mahjong machine stacking device, the card storage guardrail has a backrest plate extending toward the card stacking seat, and the card stacking seat includes a flexible member, one end of which is fixedly connected to the backrest plate, and the other end of the flexible member is fixedly arranged below the card output end of the card feeding mechanism;

[0027] The bottom end of the backrest plate is provided with a first avoidance opening for preventing the backrest plate from colliding with the card feeding mechanism due to movement with the card storage plate. The flexible member is squeezed by the mahjong cards to form the card receiving platform and the card stacking guardrail.

[0028] When no mahjong tiles are supported or when the backing plate moves with the tile storage plate, the flexible member can be bent arbitrarily. Only when the mahjong tiles fall onto the flexible member, the flexible member is stretched by the mahjong tiles to form the above-mentioned tile supporting platform and tile stacking guardrail.

[0029] This card stacking seat structure not only makes it possible for the card stacking seat to move synchronously with the card storage board, but also when the back plate moves with the card storage board, the flexible part can be bent arbitrarily, that is, the movement of the back plate will only compress the card stacking space without affecting other structures of the mahjong machine.

[0030] Since the backrest plate itself is located in front of the card delivery bracket in a "top-turned-out" posture, arranging a first avoidance opening at the bottom end of the backrest plate can effectively avoid the backrest plate from colliding with the card delivery bracket.

[0031] In the above-mentioned mahjong machine stacking device, the stacking mechanism includes a card pushing machine head box, on which is fixedly provided an auxiliary card holding plate arranged parallel to the card holding platform, and the end of the flexible member close to the card feeding channel is fixedly connected to the auxiliary card holding plate.

[0032] Preferably, in the above-mentioned mahjong machine stacking device, a second avoidance opening is formed between the auxiliary card holding plate and the backrest plate to prevent the backrest plate from colliding with the auxiliary card holding plate due to the movement of the card storage plate. The second avoidance opening also facilitates the retraction of the periphery of the mahjong machine.

[0033] In order to further prevent the backing plate from colliding with the auxiliary card-bearing plate or the card-feeding mechanism, in the above-mentioned mahjong machine stacking device, the angle between the plane where the backing plate is located and the plane where the card-bearing platform is located is ≥90°;

[0034] The top end of the backrest plate is provided with a plate guard portion, which is offset from the plane where the backrest plate is located toward the plate support platform side.

[0035] Obviously, the angle between the plane where the backrest plate is located and the plane where the card receiving platform is located should not be too large, otherwise it will also affect the subsequent card raising; preferably, the angle is set to about 100 degrees. Correspondingly, the card storage platform and the card storage guardrail of the card storage board also have the same angle, so that the card pile can be smoothly transferred from the card stacking seat to the card storage board.

[0036] The function of the card guard is to restrict the mahjong tiles on the card stacking seat to prevent the mahjong tiles from rushing out of the card stacking seat due to the excessive inclination angle of the card stacking guardrail relative to the card receiving platform.

[0037] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0038] (1) The present invention arranges the card receiving platform to be tilted downward from the side close to the card feeding mechanism to the side far away from the card feeding mechanism, that is, the tilting direction of the card receiving platform is basically consistent with the diving posture of the mahjong tiles when they fall. Therefore, when the mahjong tiles fall onto the card receiving platform, the entire bottom surface of the mahjong tiles can contact the card receiving platform at the same time, or the bottom surface of the mahjong tiles can contact the card receiving platform at a small angle, and then slide along the card receiving platform for a certain distance before abutting against the stacking guardrail; the second mahjong tile is also stacked in the same way, so that the card planting phenomenon can be completely eliminated under the premise that the card receiving platform remains static; and the overall structure of the card stacking stand is simple, no redundant driving structure is required, and the manufacturing cost is low.

[0039] (2) In the present invention, the card storage board also has the same tilted state as the card stacking stand, so that the mahjong tiles can be smoothly transferred from the card stacking stand to the card storage board.

[0040] (3) The present invention sets the card storage plate to move toward the card raising plate to send out the mahjong tiles, so that the area of ​​the mahjong machine has the opportunity to be reduced. When the mahjong machine needs to be packaged and transferred, a smaller packaging box can be used to package the mahjong machine, thereby saving transportation costs and transportation space; moreover, the card raising plate can be set closer to the center of the shuffling barrel to facilitate players to grab cards; and the card stacking seat and the card storage plate are on the same plane. If only the card storage plate has a retractable displacement but the card stacking seat does not, the periphery of the mahjong machine is still difficult to retract; in order to make the periphery of the mahjong machine retract as a whole, the present invention sets the card stacking space to be deformable, and the card stacking guardrail can move synchronously with the card storage plate.

[0041] (4) The present invention utilizes a flexible member to connect the auxiliary card-holding plate and the backing plate on different planes. When stacking cards, the flexible member will be squeezed to form a card-holding platform together with the auxiliary card-holding plate and a card-stack guardrail together with the backing plate. When there are no mahjong tiles in the stacking space, the flexible member facilitates the movement of the backing plate and the compression of the stacking space without changing other structures of the mahjong machine and causing any impact.

[0042] (5) In the present invention, a first avoidance opening is formed between the bottom end of the backrest plate and the plane where the card-receiving platform is located, and the first avoidance opening can prevent the backrest plate from colliding with the card-feeding mechanism due to the movement with the card-storing plate; a second avoidance opening is formed between one end of the auxiliary card-receiving plate facing the backrest plate and the plane where the backrest plate is located, and the second avoidance opening can prevent the backrest plate from colliding with the auxiliary card-receiving plate due to the movement with the card-storing plate, and at the same time provides convenience for the outer retraction of the mahjong machine.

[0043] (6) In order to further prevent the backrest plate from colliding with the auxiliary card receiving plate or the card feeding mechanism, the present invention sets the angle between the plane where the backrest plate is located and the plane where the card receiving platform is located to be ≥90°, and sets a card guard at the top of the backrest plate. The function of the card guard is to restrict the mahjong tiles on the stacking seat and prevent the mahjong tiles from rushing out of the stacking seat due to the excessive inclination angle of the stacking guard relative to the card receiving platform. Correspondingly, the card storage platform and the card storage guard of the card storage board also have the same angle, so that the card pile can be smoothly transferred from the stacking seat to the card storage board.

[0050] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0051] Example 1

[0052] like Figure 1 , Figure 2 and Figure 3 As shown, the present embodiment is a mahjong machine stacking device, comprising a stacking mechanism (1), wherein the stacking mechanism 1 comprises a stacking seat 11, a card feeding bracket 101 of the card feeding mechanism 100 is formed with a card feeding channel 102, and the mahjong cards sucked up from the shuffling barrel are all sent to the stacking seat 11 at the card outlet of the card feeding channel 102 through the card feeding channel 102, so as to be stacked into a pile of cards.

[0053] A stacking and pushing mechanism 2 and a card storage plate 12 are respectively provided on opposite sides of the card stacking seat 11. The stacking and pushing mechanism 2 includes a card pushing head box 21 fixed on the frame. The card pushing head box 21 is provided with a card pushing head 22 for pushing the card piles on the card stacking seat 11 one by one onto the card storage plate 12. The card pushing head 22 implements the card pushing action in a conventional structure, so it will not be repeated in this embodiment.

[0054] like Figure 4 As shown, in this embodiment, a card receiving platform 200 is formed on the card stacking seat 11. Taking receiving two layers of card piles as an example, the height difference between the card receiving platform 200 facing the card delivery channel 102 and the card delivery channel 102 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.

[0055] 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 102, or it can be lifted and set at the card output end of the card delivery channel 102. In actual circumstances, it can be fixedly set at the card output end of the card delivery channel 102; 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 102.

[0056] At the card outlet of the card delivery channel 102, the mahjong tiles fall in a diving state. If the card receiving platform 200 is arranged horizontally, the front end of the mahjong tiles will continue to rush forward due to inertia after contacting the card receiving platform 200, resulting in the tile falling. In order to solve this problem, the card receiving platform 200 is arranged to be tilted downward from the side close to the card delivery channel 102 to the side away from the card delivery channel 102 in this embodiment, and a stacking guardrail 300 is formed on the side of the card receiving platform 200 away from the card delivery channel 102.

[0057] Since the inclination direction of the card receiving platform 200 is consistent with the inclination 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 stacking guardrail 300; the second mahjong tile is also stacked in the same way, so that the tiles can be prevented from being planted while the card receiving platform 200 remains static.

[0058] In this embodiment, the inclination angle of the card receiving platform 200, that is, the angle between the card receiving platform 200 and the horizontal plane can be set between 5° and 60°, preferably between 10° and 30°; preferably, it is close to the inclination angle when the mahjong tiles fall. Since the stacking seat 11 is inclined, in order to facilitate the transfer of mahjong tiles from the stacking seat 11 to the card storage board 12, the card storage board 12 also has the same inclination state as the stacking seat 11. That is, the card storage board 12 of this embodiment includes a card storage platform 12a on the same plane as the card receiving platform 200, and a card storage guardrail 12b on the same plane as the stacking guardrail 300, and the card storage guardrail 12b is also fixed on one side of the card storage platform 12a to prevent the mahjong tiles from sliding off the card storage platform 12a, and the side opposite to the card storage guardrail 12b is the card outlet of the card storage platform 12a.

[0059] In this embodiment, the card storage board 12 has a card storage position located on the side of the card receiving platform 200 for receiving mahjong tiles, and a card pushing position that moves toward the card raising board to send the mahjong tiles out from the card outlet side. The card raising board in this embodiment can be vertically raised to raise the cards, or can be inclined to raise the cards.

[0060] like Figure 3 As shown, the movement of the card storage plate is driven by the card loading drive mechanism 5. 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 storage plate 12 and the transmission cam 52 are transmitted through a card pushing transmission assembly 54.

[0061] like Figure 5 Shown, combined Figure 3 It can be seen that the card pushing transmission component 54 includes an S-shaped card pushing track 541 arranged 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 track midpoint 541a, and 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 6 As shown, the transmission cam 52 has a card pushing roller 542 at a radial position that rolls with the S-shaped card pushing track 541.

[0062] In this embodiment, the card pushing roller 542 has four movement processes: card pushing preparation position (from the midpoint of the track to the starting point of the pushing stroke), card pushing position (from the starting point of the pushing stroke to the midpoint of the track), return preparation position (from the midpoint of the track to the starting point of the return stroke) and return position (from the starting point of the return stroke to the midpoint of the track).

[0063] When the transmission cam 52 rotates, the card pushing roller 542 first rolls from the track midpoint 541a along the pushing section 541b to the pushing starting point 541d, ready to push the cards; in this process, the rolling track of the card pushing roller 542 is exactly concentric with the rotation track of the transmission cam 52, so the card storage plate 12 keeps its position unchanged; the transmission cam 52 continues to rotate, but the card pushing roller has reached the card pushing starting point 541d and cannot move forward, and can only roll in the opposite direction from the pushing starting point 541d along the pushing section 541b to the track midpoint 541a. This rolling track is opposite to the rotation direction of the transmission cam 52, so the card pushing roller 542 will squeeze the groove wall of the S-shaped card pushing track 541, so that the card storage plate 12 moves toward the card raising board to push the mahjong cards flatly onto the card raising board;

[0064] The transmission cam 52 continues to rotate, and the card pushing roller 542 continues to roll from the midpoint 541a of the track along the return section 541c to the return starting point 541e, preparing for the return journey; in this process, the rolling trajectory of the card pushing roller 542 is also concentrically arranged with the rotation trajectory of the transmission cam 52, so the card storage plate 12 also keeps its position unchanged; the transmission cam 52 continues to rotate, but the card pushing roller has reached the return starting point 541e and cannot move forward, and can only roll in the opposite direction from the return starting point 541e along the return section 541c to the midpoint 541a of the track. This rolling trajectory is opposite to the rotation direction of the transmission cam 52, so the card pushing roller 542 will squeeze the groove wall of the S-shaped card pushing track 541, causing the card storage plate 12 to return to the initial position, waiting for the card pile from the card stacking seat 11.

[0065] In this way, the transmission cam 52 rotates one circle, and the card storage plate 12 completes a card pushing process.

[0066] When the card storage board 12 has the displacement to move toward the card raising board 3, the card raising board 3 can be arranged closer to the center of the shuffling barrel, making it more convenient for the player to grab the cards.

[0067] And, if Figure 1 and Figure 2 and Figure 3 As shown, the card storage board 12 of this embodiment is movably mounted on the card pushing seat 6; and in the moving direction of the card storage board 12, the support surface of the card pushing seat 6 is narrower than the card storage board, and the card storage board 12 at the starting point of pushing cards is mounted on the support surface on the side close to the card raising board, while the side away from the card raising board is suspended; and the card loading drive mechanism 5 is arranged on the side of the card pushing seat 6 facing the card raising board. Therefore, when the card storage board 12 moves along the support surface toward the card raising board, the outer space of the card pushing seat 6 will be gradually vacated, thereby greatly retracting the periphery of the mahjong machine, making it convenient to use a smaller packing box to pack the mahjong machine.

[0068] 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 periphery of the mahjong machine, the stacking seat 11 is also configured to have a compression space in this embodiment. Therefore, the card receiving platform 200 and the stacking guardrail 300 in this embodiment are not completely rigid planes, but have both rigid parts and flexible parts.

[0069] Specifically, by Figure 2 and Figure 4 It can be seen that the card stacking seat 11 of the present embodiment includes a backrest plate 11a, an auxiliary card-holding plate 11c and a flexible member 11e, wherein the backrest plate 11a and the card storage guardrail 13b are integrally formed, and the auxiliary card-holding plate is fixedly arranged on the top of the card pushing head machine box 21, and the planes where the two are located intersect, but the two are not connected to each other; the two ends of the flexible member 11e are respectively fixedly connected to the backrest plate 11a and the auxiliary card-holding plate 11c, and the flexible member 11e can be bent arbitrarily. Only when the mahjong tiles fall onto the card stacking seat 11, the flexible member 11e will be squeezed by the mahjong tiles and form a card holding platform 200 together with the auxiliary card-holding plate 11c, and form a card stacking guardrail 300 together with the backrest plate 11a.

[0070] like Figure 2 As shown, due to the influence of the inclination of the card receiving platform 200 relative to the horizontal plane, the backrest plate 11a is located on the opposite side of the card feeding mechanism 100 with the top end turned outward. When the backrest plate 11a moves toward the card receiving side of the card receiving platform 200, that is, the card feeding mechanism 100 is located, the bottom end of the backrest plate 11a is very likely to collide with the card feeding mechanism 100 or the auxiliary card receiving plate 11c, thereby limiting the moving distance of the backrest plate 11a.

[0071] In this embodiment, the flexible member 11e can be made of cloth. In addition, in order to form a flat card-bearing platform 200, the flexible member 11e is preferably completely covered with the card-bearing platform 200 to avoid unevenness between the flexible member 11e and the auxiliary card-bearing plate 11c. Obviously, at the end of the stacking card guardrail 300, the flexible member 11e can also be set to be equivalent to the height of the card pile so that the card pile can be neatly transferred. In this case, it is more appropriate to bond the flexible member 11e to the auxiliary card-bearing plate 11c or the backing plate 11a through the back adhesive layer. Since the card-bearing platform 200 is inclined, a card-guarding portion 11f inclined toward the card-receiving side of the card-bearing platform 200 can be selectively set at the top of the backing plate 11a to protect the mahjong tiles; the card-guarding portion 11f is preferably formed integrally with the backing plate 11a, and the same card-guarding portion 12c can also be set on the card storage guardrail 12b.

[0072] In order to further prevent the backrest plate 11a from colliding with the auxiliary card-carrying plate 11c or the card-delivering bracket 11, the angle between the plane where the backrest plate 11a is located and the plane where the auxiliary card-carrying plate 11c is located is set to be greater than or equal to 90° in this embodiment to offset the inclination of the auxiliary card-carrying plate 11c. Obviously, the angle should not be too large, otherwise it will also affect the subsequent card raising; preferably, the angle is set to about 100°; accordingly, the card storage platform 12a of the card storage board 12 and the card storage guardrail 12b also have the same angle, so that the card pile can be smoothly transferred from the card stacking seat 11 to the card storage board 12.

[0073] 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 a card stacking guardrail 300. At this time, the outer periphery of the mahjong machine cannot be retracted.

[0074] The working principle of a mahjong machine stacking device in this embodiment is as follows:

[0075] The card delivery mechanism 100 delivers the mahjong tiles sucked up from the shuffling bucket to the stacking seat 11 through the card delivery channel 102. Since the card receiving platform 200 on the stacking seat 11 is tilted downward from its card receiving side to the stacking guardrail side, the entire bottom surface of the mahjong tiles falling from the card discharging end of the card delivery channel 102 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 and then abut against the stacking guardrail 300; the second mahjong tiles are also stacked in the same way, so that the card planting can be prevented under the premise that the card receiving platform 200 remains static;

[0076] The card pushing head 22 pushes the card piles on the card stacking seat 11 onto the card storage plate 12. After a preset number of card piles are stored on the card storage plate 12, the card loading drive mechanism 5 is started. Under the interaction of the card pushing roller 542 and the S-shaped card pushing track 541, the transmission cam 52 first drives the card storage plate 12 to move toward the card raising plate to push the mahjong cards on the card storage plate 12 onto the card raising plate, and then drives the card storage plate 12 to return to the initial position to wait for the next card storage. During the movement of the card storage plate 12, the back plate 12a moves synchronously with the card storage plate to compress the card stacking space, so that the outer periphery of the mahjong machine is retracted as a whole.
