Description

Technical Field

[0001] The invention relates to the field of mahjong machine manufacturing, in particular to a mahjong machine and a stacking and pushing card structure thereof. Background Art

[0002] With the continuous improvement of living standards, people pay more and more attention to leisure and entertainment life, and convenient and labor-saving automatic mahjong machines are gradually becoming popular among people.

[0003] Patent document with publication number CN200966910Y discloses a ramp card-discharging device for a fully automatic mahjong machine, which has a table top with a card-discharging opening in the center. Four rectangular windmill-shaped card-discharging openings are arranged on the table top and are inclined at an angle to the edge of the table top. There are four arc-shaped card storage slots arranged in a windmill shape below the table top. A card-feeding push head is installed at the end of each card storage slot, and the push head is connected to the push head motor via a card-feeding wire rope. A support plate door strip is provided on each card-discharging opening, one end of the support plate door strip is hinged to the card-discharging opening, and the other end is movably connected to the lifting mechanism. The four card outlets are arranged in a windmill shape, and each card outlet is inclined at an angle to the bottom edge of the table, that is, the windmill shape is inclined, so the tabletop can be made smaller, and the inclination of the card strips also conforms to the habits of card players; secondly, when playing cards, the whole card strip is not raised to the tabletop after being piled up, but is pushed onto the tabletop along the slope, so the space inside the machine can also be reduced, thereby reducing the volume of the whole machine. However, in the card outlet device, the entire card storage tank is arranged in a slope shape, the resistance of the card loading process is large, the load of the wire rope motor is large, the steel wire is easy to shake and break, the card loading process is not stable enough, the service life of the wire rope is short, the card storage tank, the stacking pusher head and the conveying device (the mechanism for picking up mahjong tiles from the large plate and conveying them to the stacking pusher head) are arranged unreasonably, and the conventional four-sided independent stacking pusher head is difficult to push the mahjong tiles to the card inlet of the card storage tank track, and the host height is relatively high.

[0004] The patent document with publication number CN201783185U discloses a fully automatic mahjong machine with a chain-driven ramp card-discharging device, which has four liftable card-lifting plates hinged to the table, one end of which is a card inlet, and the outer side of each card-lifting plate is a conveyor belt, one side of the conveyor belt is equipped with a stacking mechanism, and an arc-shaped card storage slot is provided on the outer side of the four conveyor belts, and a ring-shaped closed chain is provided under the slot, and a vertical chain rod is installed on the chain at a set interval. Although the card-discharging device uses a chain to push mahjong tiles, which overcomes the problem of low life of the wire rope, the machine has a large working noise, and the plane size of the host is increased, and other defects are not improved.

[0005] The patent document with the publication number CN102133480A discloses a fully automatic mahjong machine, including a card delivery system, a card loading system, a card raising system and a shuffling plate, wherein the card loading system includes four card pushing devices, four card loading tracks and a chain transmission device. Among them, the height of the card delivery system is substantially flush with the height of the card raising system. Although this reduces the height of the host, the arrangement position of the card raising system will interfere with the shuffling of the plate and the absorption of mahjong tiles by the card delivery system, and is only suitable for small mahjong tiles. In addition, the card delivery system's card outlet and the card loading track's card inlet are arranged unreasonably, and the card pushing device does not have a card stacking function. The mahjong tiles are stacked on the card receiving table by themselves, so that the mahjong tiles are stacked unevenly and easily dislocated, resulting in the mahjong tiles being unable to enter the card loading track, causing chaos in the card loading track and other faults. In addition, after adopting a horizontal card loading track, the mahjong tiles close to the card loading track's card outlet are very easy to fall out of the card outlet and fall back into the shuffling plate; the use of a chain and a card loading flag wheel structure is noisy.

[0006] The automatic mahjong machine disclosed in the patent documents with publication numbers CN201906453U and CN201949619U has a card storage board in the card storage track of the mahjong machine that is tilted and docked with the card receiving board at one end. The stacking card pusher pushes the mahjong tiles on the card receiving board onto the card storage board. After the mahjong tiles on the card storage board are arranged in a row, the loading card pusher pushes the entire row of mahjong tiles to the loading card assembly. Since the stacking card pusher is provided with an avoidance groove and the loading card pusher is provided with a push rod, the two pushers can be arranged crosswise up and down, so that the two can completely avoid each other through the avoidance groove when pushing cards respectively. However, because the card storage track must pass above the conveying part of the card feeding device, the height of the mahjong machine host is relatively high (the height of the card feeding device and the loading card device are superimposed). In addition, the L-shaped card storage track is relatively short and has poor versatility.

[0007] The automatic mahjong machines disclosed in the patent documents with publication numbers CN103861280A and CN104645608A also have the problems of high main machine height (the height of the card feeding device and the card loading device is superimposed), short L-shaped card storage track, etc. Moreover, after adopting a horizontal card loading track, the mahjong tiles close to the card output port of the card loading track are very easy to fall out of the card output port and fall back into the shuffling plate; the steel wire rope is used to drive the card loading pusher to move, and the steel wire rope has serious friction with the side wall of the track, resulting in a short service life.

[0008] The patent document with publication number CN204699375U discloses an automatic mahjong machine with an improved structure, including a card feeding system, a card loading system, a card raising system and a card shuffling plate. The card feeding system includes four card feeding mechanisms, each of which includes a transmission frame and a conveyor belt fixed on the transmission frame. The four card feeding mechanisms are connected in sequence to form a rectangular structure, and the card shuffling plate is arranged in the four card feeding mechanisms. The card loading track adopts a whole large arc structure, which reduces the friction between the mahjong tiles and the card loading track, and ensures a faster card loading speed and a smaller card loading noise. In addition, the layout position of the card loading system and the card feeding system is designed to avoid partial overlap, which reduces the height of the host. However, because the card feeding device adopts a straight line to transport mahjong tiles, the card outlet of the card feeding device and the card inlet of the card loading track still cannot be reasonably arranged, the stacking device has a large card pushing resistance and is easy to get stuck, and the large arc card loading track causes the size of the mahjong machine table to increase.

[0009] A series of patent documents with publication numbers CN105381604, CN105381604, etc. disclose a mahjong machine, comprising a central lifting assembly located in the center of a frame bottom plate, a shuffling plate and a card scraper, four sets of card picking and transporting systems are arranged around the shuffling plate, the card picking and transporting system comprises a card feeding device for picking up mahjong tiles one by one from the shuffling plate and sending them out, a card pushing device for stacking mahjong tiles into a pile and pushing them out, and a ramp card discharging device for sending the arranged mahjong tiles in multiple piles onto the mahjong machine table along a slope, the ramp card discharging device comprises a card loading assembly and a card lifting assembly; wherein, the card loading assembly comprises a card storage slot for storing multiple piles of mahjong tiles, the card storage slot has at least one arc bend, a card loading guide rail is installed on the inner side wall of the card storage slot, a card loading push head is slidably arranged on the card loading guide rail, and the card loading push head is driven by a wire rope card loading drive mechanism to slide along the card loading guide rail.

[0010] According to the applicant's practice, the existing scheme still has the following shortcomings: 1. The stacking device can only realize the function of pushing mahjong tiles horizontally, and generally can only push mahjong tiles to the entrance end of the card storage slot. Therefore, this type of mahjong machine has a low utilization rate of the internal space of the main base, and needs to be equipped with a card loading device with a larger stroke. 2. The output stroke of the card loading component is large, and it needs to be pushed from the starting end of the card storage slot to the end. For example, in the Chinese utility model patent with the authorization announcement number "CN207384808U", the card storage slot is circular, so the push head in the card loading component moves in a circular motion. Since the card storage slot needs to hold all the cards after the cards are sorted, the card storage slot must maintain a certain stroke length. In a specific stroke length, the circular shape occupies the largest space and has the lowest space utilization rate, so it is urgently needed to be improved. Summary of the invention

[0011] In order to solve the above problems, the first purpose of the present invention is to provide a stacking and pushing card loading structure. Among them, the stacking and pushing machine head adopts the swinging form of a push rod to push the mahjong tiles, and has a large curved pushing stroke, which is conducive to the utilization of the internal space of the main base of the mahjong machine, and only needs to be equipped with a card loading mechanism with a small stroke. The card loading component adopts a two-stage pushing scheme of a first card loading rod and a second card loading rod, and the shape of the card storage slot can be adaptively improved according to the internal space of the main base of the mahjong machine. Under the premise of a specific stroke length of the card storage slot, this scheme can optimize the internal space design of the mahjong machine and improve space utilization.

[0053] The preferred embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0054] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0055] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0056] Embodiment 1:

[0057] like Figures 1 to 12 An automatic mahjong machine shown includes a frame, a main frame 1 arranged on the frame, a central control panel assembly 2 arranged in the main frame 1, a shuffle plate, and four sets of card picking and transporting systems 10 arranged around the shuffle plate. The main frame 1 includes a bottom plate 11, a desktop panel, and a frame connecting the edge of the bottom plate 11 and the edge of the desktop panel; a main frame cavity is formed between the bottom plate 11, the desktop panel and the frame, the shuffle plate is located in the center of the main frame cavity, and the four sets of card picking and transporting systems are respectively located on the four sides of the shuffle plate and arranged around the shuffle plate. A card inlet is provided at the center of the desktop panel, and the card inlet is located above the center of the main frame cavity. The lower end of the central control panel assembly 2 is connected to the main frame cavity, and the lifting and lowering movements relative to the desktop panel are realized through a lifting structure, thereby realizing the opening and closing of the card inlet.

[0058] Each set of card picking and transporting system includes a card feeding mechanism 3 for sucking, picking up and feeding mahjong tiles on the shuffling plate, a card stacking component for stacking multiple mahjong tiles into a pile, a card pushing component for pushing the mahjong tiles into a pile, and a ramp card discharging device for pushing the mahjong tiles onto the desktop.

[0059] The card feeding mechanism 3 can be the card feeding mechanism 3 recorded in the patent document with reference announcement number "CN202682759U", including a card feeding box inner shell and a card feeding box outer shell 31, between which a card suction wheel, a plurality of conveyor belt wheels and a card feeding conveyor belt wound on the card suction wheel and the plurality of conveyor belt wheels are installed, so that a card feeding channel for transferring mahjong cards is formed between the card feeding box inner shell and the card feeding box outer shell 31, and the card suction wheel is arranged at the inlet end of the card feeding channel; the card feeding box inner shell is provided with a card guide groove for straightening the mahjong cards into the card feeding channel along the length direction of the mahjong cards at the inlet end of the card feeding channel, and a card blocking frame 32 is provided at the outlet end of the card feeding channel, and the card blocking frame 32 can be an independent bracket arranged separately, but a more preferred scheme is to fix the card blocking frame 32 with the card loading bracket in the ramp card discharging device or form it in one piece, and the two can be assembled and combined in advance through the above-mentioned fixed connection or one-piece forming method, so as to be installed in the main frame together to improve the assembly efficiency. In the card feeding mechanism 3, the card suction wheel absorbs the mahjong cards in the shuffle tray, and then the mahjong cards are sent into the card feeding channel through the card feeding conveyor belt, and the conveying angle of the absorbed mahjong cards is limited and guided by the card guide groove, that is, the mahjong cards are limited to be sent into the card feeding channel only along their length direction, thereby completing the basic process of card sorting. In addition, the card feeding mechanism 3 also includes a card feeding detection device for detecting whether the card outlet of the card feeding mechanism has sent mahjong cards to the card receiving table (included in the stacking card assembly). The card feeding detection device can be set on the card blocking frame, and when it is set on the card blocking frame, it is preferably set on the side wall of the card blocking frame; when the card blocking frame is only provided with a front baffle, the card feeding detection device can also be installed on any other mountable bracket on the side of the card blocking frame. However, it is more preferably set on the side wall of the push block of the push card assembly to improve the detection accuracy and reliability.

[0060] In addition, the card delivery mechanism 3 can also be a card delivery mechanism described in the patent document with reference announcement number "CN206881091U". The card delivery mechanism includes a card delivery box inner shell and a card delivery box outer shell, between which a card suction wheel and a card delivery conveyor belt are installed, so as to form a card delivery channel for transferring mahjong tiles between the card delivery box inner shell and the card delivery box outer shell, the card suction wheel is arranged at the card inlet of the card delivery channel, and the card delivery box inner shell is provided at the card inlet of the card delivery channel with a card guide groove for straightening the mahjong tiles into the card delivery channel along the length direction of the mahjong tiles. Under this scheme, the card stacking component adapted thereto specifically includes a card support bracket, and a card support conveyor belt installed on the card support bracket, the conveying direction of the card support conveyor belt matches the conveying direction of the card delivery conveyor belt, the card support conveyor belt is arranged below the card outlet of the card delivery channel, and the card support surface of the card support conveyor belt is lower than the card outlet of the card delivery channel by at least the thickness of one mahjong tile. The stacking principle of the above-mentioned stacking assembly is as follows: the first mahjong tile is sent out from the card outlet of the card delivery channel. Because the card receiving conveyor belt is lower than the card delivering conveyor belt, when the first mahjong tile is sent out from the card outlet and exceeds one-half, the front end of the first mahjong tile falls onto the card receiving conveyor belt under the action of its own gravity, and along with the conveyance of the card receiving conveyor belt, the rear end of the first mahjong tile also falls on the card receiving conveyor belt. After the first mahjong tile falls onto the card receiving conveyor belt and is blocked by the card blocking member and cannot move, the second mahjong tile continues to move toward the card receiving conveyor belt. Since the height difference between the card receiving conveyor belt and the card delivering conveyor belt is greater than the thickness of the mahjong tiles, the second mahjong tile is directly stacked on the first mahjong tile to achieve the stacking of one pile of mahjong tiles.

[0061] In addition, in the above scheme, a card block and a side block are provided near the card conveyor belt, the card outlet of the card feeding device and the card block are respectively located on two opposite sides of the card conveyor belt, and the side block and the mahjong card ejection outlet are respectively located on the other opposite sides of the card conveyor belt. The card delivery detection device for detecting whether the card outlet of the card feeding device has delivered mahjong cards to the card conveyor belt can be provided on the card block, but is preferably provided on the side block to improve the detection accuracy and reliability. Similarly, the card block and the side block can be independent brackets provided separately, but a more preferred scheme is to fix the card block and the side block to the card loading bracket in the ramp card output device or to form them in one piece.

[0062] On the basis of the card feeding mechanism 3 described in the patent document with reference publication number “CN202682759U”, a stacking device described in the Chinese utility model patent with publication number “CN207384806U” may be used. The stacking and pushing device comprises a card pushing head, a card receiving platform, a card blocking frame and a card storage plate, wherein the card pushing head and the card blocking frame are respectively located on two adjacent sides of the card receiving platform, the card outlet and the card blocking frame of the card feeding device are respectively located on two opposite sides of the card receiving platform, and the card pushing head and the card storage plate are respectively located on two opposite sides of the card receiving platform; it also comprises a card pushing slider, a card receiving cam, a card receiving swing arm, a stacking and pushing motor and a shell, wherein the stacking and pushing motor is mounted on the shell and drives the card receiving cam to rotate, and the card receiving cam is provided with a card receiving curved groove and a card pushing roller. As shown in the figure, one end of the card receiving swing arm is provided with a rotating shaft 1 and swings up and down around the rotating shaft, and the card receiving swing arm is provided with a card receiving roller, which moves in the card receiving curved groove, and the other end of the card receiving swing arm (provided with a connecting roller) is movably connected to the card receiving platform that rises and falls (connected to the slide groove through the connecting roller), the card pushing slider is connected to the shell for left and right sliding, the card pushing slider is provided with a card pushing curved groove, the card pushing roller moves in the card pushing curved groove, and the card pushing slider is fixedly connected to the card pushing head.

[0063] In another embodiment, the stacking assembly includes a lever 54 hingedly arranged in the middle, and a card receiving platform 541 connected to the first end of the lever 54; the middle of the lever 54 can be hinged on the inner shell of the card box or the outer shell of the card box 31 of the card feeding mechanism 3, and the second end of the lever 54 swings up and down during the rotation of the rotating shaft 53. In practice, as long as the above function can be achieved, the two ends of the lever 54 can be driven to float alternately, and its implementation structure is not unique. In one embodiment, the lever 54 is driven by a cam 55. The specific solution is that a slide groove 56 is opened on the circumferential side wall of the cam 55, and the slide groove 56 surrounds the circumferential side wall of the cam 55. The slide groove 56 includes a first slide groove section 561 and a second slide groove section 562. The first slide groove section 561 is an arc section arranged along the circumference of the cam, and it is always at the same height position of the cam, while the second slide groove section 562 is an open U-shaped, and the U-shaped end of the second slide groove section 562 is connected to the first slide groove section 561. The second chute sections 562 on both sides of the U-shaped bottom of the second chute section 562 are respectively a lifting section 562b and a sinking section 562c. The second end of the lever 54 is arranged in the chute 56. During the rotation of the cam, the second end of the lever 54 moves relative to the chute 56. Due to the relative sliding, a roller is arranged at the second end of the lever 54 in the preferred embodiment. In the above embodiment, when the second end of the lever 54 passes through the first chute section 561, since the first chute section 561 is always at the same axial position of the cam, the height of the second end of the lever 54 does not change, the lever 54 does not swing, and the card receiving platform 541 on the second end of the lever 54 remains at the same height. When the second end of the lever 54 passes through the second chute section 562, the second end of the lever 54 swings up and down along the second chute section 562, so that the cards are stacked in the same cycle. The specific solution is that, first, when the second end of the lever 54 is in the first chute section 561, the card receiving platform 541 matches the card outlet of the card delivery mechanism (is flush with or slightly lower than the card outlet), and the card outlet of the card delivery channel delivers the first mahjong tile directly into the card receiving platform 541; then, the second end of the lever 54 passes through the sinking section, and the card receiving platform 541 is in a descending process. When it is at the U-shaped bottom of the second chute section 562, the card receiving platform 541 is in the lowest position. At this time, the card outlet of the card delivery channel delivers the second mahjong tile directly stacked on the first mahjong tile to achieve the stacking of one pile of mahjong tiles; then, the second end of the lever 54 passes through the lifting section, and the card receiving platform 541 is in a lifting process, and finally resets to match the card outlet of the card delivery mechanism, so that subsequent card pushing actions can be performed.The above scheme is to drive the lever 54 with the help of the slide groove 56 on the cam 55, and realize the movement of the card receiving platform 541 between two height positions; at the same time, the card feeding mechanism 3 delivers the mahjong cards, and a card blocking frame 32 is arranged outside the card outlet of the card feeding mechanism 3, and the card blocking frame 32 is used to block the mahjong cards from continuing to move forward, while the card receiving platform 541 receives the mahjong cards on the front side of the card blocking frame 32, and realizes the card stacking action by moving up and down.

[0064] Based on the above multiple implementations, the pusher assembly includes a push rod 58 and a push block 59 disposed on the push rod 58. The first end of the push rod 58 is positioned by a shaft and driven by a power component, that is, the push rod 58 can rotate along its first end as the axis; further, the push block 59 is fixed to the second end of the push rod 58 and rotates with the push rod 58. In the above scheme, the push rod 58 rotates along its first end; the push block 59 on the second end of the push rod 58 moves to push the cards; and the piles of mahjong tiles stacked on the card receiving table 541 or the card receiving conveyor belt are pushed out. In one of the driving modes of the push rod 58, the pusher assembly further includes a crank 57, which is driven to rotate by a rotating component, and the crank 57 drives the push rod 58; specifically, the first end of the crank 57 is sleeved on the rotating component, so that the crank 57 can rotate along its first end as the axis; the push rod 58 is provided with a slide rail groove 50 along the direction of its rod body, and the second end of the crank 57 is arranged in the slide rail groove 50; during the rotation of the crank 57, the second end of the crank 57 moves along the slide rail groove 50 and drives the push rod 58 to rotate along its first end; in a further preferred embodiment, a roller is installed at the second end of the crank 57, so that the movement between the crank 57 and the push rod 58 is smoother. The above scheme can also be changed into another implementation scheme, in which the crank is replaced with a turntable, a slide rail groove is arranged on the turntable, and a roller is arranged on the push rod and is in the slide groove of the turntable; the principle of this scheme is also similar to the above scheme, except that the setting positions of the slide rail groove and the roller are swapped.

[0065] In a further preferred embodiment, the stacking assembly and the card pushing assembly recorded in the above embodiment can be set as a stacking and pushing machine head 5, the stacking and pushing machine head 5 includes a stacking and pushing bracket 51, and a stacking and pushing motor 52 fixed on the stacking and pushing bracket 51; the stacking and pushing bracket 51 is installed on the card feeding box housing 31 of the card feeding mechanism 3, and a rotating shaft 53 is positioned on the stacking and pushing bracket 51 through a bearing, and the stacking and pushing motor 52 drives the rotating shaft 53, and when the rotating shaft 53 is driven, the stacking and pushing assembly move in coordination. The specific embodiment is that the cam 55 is sleeved on the rotating shaft 53, and a tooth portion is provided on the upper end of the cam. The output end of the stacking and pushing motor 52 drives the cam 55 through a bevel gear, and the movement of the cam 55 drives the movement of the stacking assembly. The rotating shaft 53 is a rotating component connected to the first end of the crank 57, and the rotating shaft 53 drives the card pushing assembly to move. In order to coordinate the degree of coordination between the stacking action and the card pushing action, the track shape of the slide rail groove 50 needs to be limited. Therefore, in a further preferred embodiment, the slide rail groove 50 includes an arc segment 501 and a straight segment 502, wherein the arc segment 501 is located on the first end of the push rod 58, and the straight segment 502 extends from the end of the arc segment 501 along the rod body direction of the push rod 58. The arc segment 501 is centered on the axis center position of the first end of the crank 57, and in this embodiment, the axis center of the rotating shaft 53 is the center of the circle; and the arc center angle of the arc segment 501 is adapted to the arc center angle occupied by the second slide groove segment 562 in the above-mentioned stacking assembly. The purpose of such a setting is that when the second end of the lever 54 passes through the second slide groove segment 562, the lever 54 swings along the hinge point in the middle for one round, and its overall action is to achieve stacking; and the card pushing action must be started after the stacking is completed; but in the above-mentioned stacking process, the rotating shaft 53 and the crank 57 connected thereto will both move. If the crank 57 drives the push rod 58 to move during this process, the card pushing action will be started in advance, and the card pushing and stacking cannot be coordinated. Therefore, the arc segment 501 is set so that the crank 57 does not push the push rod 58 during the above process. The arc center angle of the arc segment 501 is matched with the center angle of the second chute segment 562 in the above stacking assembly. When the above stacking action is completed, the second end of the crank 57 enters the straight segment 502, and the crank 57 continues to move to drive the push rod 58, so that the push rod 58 moves and the card pushing action starts.

[0066] On the basis of the above scheme, the ramp card discharging device includes a card loading bracket 9, and a card loading component and a card raising component arranged on the card loading bracket 9. The card loading bracket 9 includes a card storage slot 4 and a card raising bracket 81. Among them, the card storage slot 4 is provided with a first curved segment 41, a middle transition segment 42 and a second curved segment 43 in sequence from the card inlet to the card outlet. The middle transition segment 42 is preferably provided as a middle straight segment, and the middle straight segment is basically parallel to the frame of the main frame, and is against or spaced with a small spacing inside the frame. The second curved segment 43 is a circular curve. Since the middle straight segment is close to the frame of the main frame and is basically parallel to the frame; and the mahjong arrangement direction in the existing ramp card discharging mahjong machine is arranged from the left side in front of the player to the right side and away from the player, therefore, under the structural constraint of the middle straight segment, in order to realize the arrangement direction of the above mahjong tiles, the arc center angle formed by the path including the second curved segment 43 is greater than or equal to 180°. In the above scheme, the card storage slot 4 is in a "C" shape as a whole, the card inlet of the card storage slot 4 is connected to the card receiving platform 541 or the card receiving conveyor belt, and the mahjong tiles are pushed into the card storage slot 4 by the card pushing component, and the card raising bracket is installed on the card outlet of the card storage slot 4. The pushing direction of the mahjong tiles from the card inlet to the card outlet in the card storage slot 4 is counterclockwise. As described in the above-mentioned description of the card feeding mechanism, the card retaining rack can be fixedly connected or integrally connected with the card loading bracket 9, and the card storage slot 4 and the card raising bracket 81 of the card loading bracket 9 can also be fixedly connected or integrally connected. The mahjong tiles are arranged in a reverse "G"-shaped path as a whole after the card feeding process, the card stacking process, the card pushing process and the card loading process. In the same card picking and transporting system, the card feeding direction of the card feeding mechanism 3 is substantially parallel to the card raising direction of the card raising assembly, and the card feeding mechanism 3 is located on the inner side of the card raising assembly, and the card feeding mechanism 3, the card loading assembly and the card raising assembly are all located in the "C"-shaped opening of the card storage slot 4. In the same card picking and transporting system, there is no overlap of the card feeding mechanism 3, the card loading assembly and the card raising assembly, thereby avoiding the problem of significantly increasing the height of the whole mahjong machine due to the upper and lower overlapping of the related device components caused by the interlaced arrangement in the same card picking and transporting system. Similarly, in the automatic mahjong machine, the four groups of card picking and transporting systems are respectively located on the four sides of the shuffling plate, and there is no upper and lower overlapping position between the two adjacent groups of card picking and transporting systems in space, thereby avoiding the problem of significantly increasing the height of the whole mahjong machine due to the upper and lower overlapping of the related device components caused by the interlaced arrangement between the adjacent card picking and transporting systems in the prior art, and the overall height of the machine can be correspondingly reduced compared to the machine in the prior art in which the card storage slot is stacked on the card feeding device. In addition, in other implementation schemes, the card loading bracket 9 in the four-group card picking and transporting system can be fixedly connected or integrally formed as a whole, or the card raising bracket 81 in the card loading bracket 9 in the four-group card picking and transporting system can be fixedly connected or integrally formed as a whole, or the card storage slot 4 and the card raising bracket 81 are separately connected to the main base.The above-mentioned fixed connection method or integrated molding method is to assemble and combine the four card-loading brackets 9 or the four card-raising brackets 81 in advance, and then install them together into the main base to improve the assembly efficiency. The above-mentioned four sets of card picking and transportation systems are reasonably arranged, and the four rows of mahjong tiles directly raised from the four-sided card-raising openings are arranged in a windmill shape. In this way, the area on the left hand side where the player is accustomed to placing the cards will be larger, which is easier to place mahjong tiles. Players do not need to deliberately move the mahjong tile wall to empty the card-raising area, and the user experience and comfort are better.

[0067] The card loading assembly includes a first card loading rod 71 and a second card loading rod 72 which are independently driven and operated. The first card loading rod 71 and the second card loading rod 72 are used to push mahjong tiles along the card storage slot 4. The first card loading rod 71 is used to push mahjong tiles from the starting end of the card storage slot into the mahjong tiles. The second card loading rod 72 is used to receive the first card loading rod 71 and continue to push the mahjong tiles along the card storage slot 4 to the desktop. The two-stage pushing method is adopted, which is conducive to optimizing the shape of the card storage slot 4 and improving the internal space utilization of the main base. Based on the structure of the card storage slot 4, the first card loading rod 71 mainly pushes mahjong tiles along the first curved segment 41 and the middle straight segment of the card storage slot 4. Specifically, the first end of the first card loading rod 71 is positioned by an axle rod and driven by a power component, so that the first card loading rod 71 can swing within a certain angle range along the first end as the axis, and the second end of the first card loading rod 71 runs between the inlet direction of the card storage slot 4, the first curved segment 41 and the middle straight segment. In a further preferred embodiment, the first card-loading rod 71 is the push rod 58 in the card-pushing assembly; in this embodiment, the push rod 58 not only has the function of pushing the mahjong tiles into the card storage slot 4 in the card-pushing assembly; but also can be used as the first card-loading rod 71 to push the mahjong tiles along a path along the card storage slot 4 after receiving the card-loading instruction. The push rod 58 is used as the first card-loading rod 71, which is greatly optimized in structure, eliminating a group of card-loading rods and their driving structure, not only saving manufacturing costs, but also freeing up internal space for easy space utilization. In a further preferred embodiment, the card-pushing assembly can also be used as a part of the stacking and pushing machine head 5, that is, the stacking and pushing assembly in the stacking and pushing machine head 5 adopts a linkage mode, that is, driven by the same stacking and pushing motor, and its specific implementation mode can refer to the specific structure of the stacking and pushing machine head, which further optimizes the structure and improves the space utilization.

[0068] The second card-loading rod 72 is mainly used to push mahjong tiles along the second curved segment 43 of the card storage slot 4. The positioning end of the second card-loading rod 72 is rotated and driven by the card-loading driving component 73. The card-loading driving component 73 can be preferably a card-loading motor, and the card-loading rod 72 is driven to rotate by the card-loading motor. The motion path of the movable end of the second card-loading rod 72 passes through the entire section of the second curved segment 43, and can also pass through the card outlet position of the middle straight segment. According to the above record, the second curved segment 43 is an arc, so the positioning end of the second card-loading rod 72 is in the range of the center area of ​​the second curved segment 43, and the length of the second card-loading rod 72 is between the inner wall radius and the outer wall radius of the second curved segment 43. In one embodiment, the second card-loading rod 72 is directional and rotates in a circular shape. In this scheme, the main body of the card-loading bracket and the card-lifting bracket are provided with a avoidance groove for avoiding the second card-loading rod. The setting of the avoidance groove can make the second card-loading rod rotate smoothly without obstruction. In another embodiment, the second card-loading rod 72 swings in an arc shape within a certain arc angle, and the arc angle is equal to or slightly greater than the arc center angle of the second curved segment 43. Both of the above methods can be coordinated with the first-level card-loading action of the first card-loading rod 71. Since the first card-loading rod 71 and the second card-loading rod 72 need to be pushed, there must be an intersection in their motion trajectories. In order to avoid interference between the two, the direction of programming control can be used to regulate the movements of the first card-loading rod 71 and the second card-loading rod 72; but a more preferred solution is to set the first card-loading rod 71 and the second card-loading rod 72 at different heights, so that the control method is simplified and the above purpose can be achieved.

[0069] The card lifting assembly includes a card lifting plate 83 and a card lifting driving component 82. The card lifting bracket 81 is installed on the card outlet of the card storage slot 4, and the card lifting plate 83 is arranged in the card lifting bracket 81; specifically, the distal end of the card lifting plate 83 is hinged on the card lifting bracket 81, and the card lifting plate 83 can swing within a certain range along its hinged end, thereby realizing the up and down movement of the proximal end of the card lifting plate 83. The card lifting driving component 82 drives the card lifting plate 83 to move, and the card lifting driving component 82 is preferably a card lifting motor, which is connected to the proximal end of the card lifting plate 83 through the card lifting rod rocker arm 85, the transmission arm 86 and the card lifting rod crank 87 in sequence. A card lifting port 84 is arranged on the desktop panel of the main base 1, and the card lifting plate 83 is arranged in the card lifting port 84. When the proximal end of the card-lifting supporting plate 83 is in the highest position, the card-lifting supporting plate 83 blocks the card-lifting opening 84 and is flush with the table top; when the proximal end of the card-lifting supporting plate 83 is in the lowest position, the card-lifting supporting plate 83 is inclined, and the proximal end of the card-lifting supporting plate 83 is connected with the card outlet of the card storage slot 4, which can be used for lifting cards, and the card-lifting brackets 81 on both sides of the card-lifting supporting plate 83 can be used as baffles to regulate the direction in which mahjong tiles are pushed in.

[0070] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and utility model concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

At this time, the card outlet of the card delivery channel sends out the second mahjong tile and stacks it directly on the first mahjong tile to realize the stacking of one pile of mahjong tiles; then, the second end of the lever 54 passes through the lifting section, and the card receiving platform 541 is in the lifting process, and finally resets to match the card outlet of the card delivery mechanism. The third implementation method adopts the card stacking method in the stacking and pushing device with the announcement number "CN207384806U", the card receiving platform stays at the first height and receives the first mahjong tile sent from the card feeding device; after detecting that the first mahjong tile is in place, the card receiving platform descends and stays at the second height to receive the second mahjong tile sent from the card feeding channel, and the second mahjong tile is stacked on the first mahjong tile; after detecting that the second mahjong tile is in place, the card receiving platform descends again to the third height, and during this descending process, the card feeding device is prevented from sending out the third mahjong tile.

[0076] 4) Pushing cards; pushing the completed mahjong tiles into the card storage slot; the push rod in the card pushing assembly moves, and the push rod 58 rotates along its first end; the push block 59 on the second end of the push rod 58 moves to push the cards; pushing the completed mahjong tiles stacked on the card receiving table 541 or the card receiving conveyor belt into the card storage slot;

[0077] 5) After the cards are sorted, wait for the cards to be played; repeat the above steps 1 to 4 to sort all the mahjong tiles and arrange them behind the storage slots in the order of the storage slots;

[0078] 6) Slope card output; push the sorted mahjong tiles to the table top; after receiving the card loading instruction, the movable end of the card lifting support plate 83 in the slope card output device sinks and connects with the card output port of the card storage slot 4; the first card loading rod 71 first pushes the mahjong tiles from the card input port of the card storage slot 4 along the card storage slot 4; then the second card loading rod 72 is connected to the first card loading rod 71, and all the mahjong tiles are pushed from the card storage slot 4 to the card lifting support plate 83 at one time; finally, the movable end of the card lifting support plate 83 is lifted and flush with the table top; the card output is completed.
