Description

[Technical field]

[0001] The invention belongs to the field of mahjong machine manufacturing, and in particular relates to a mahjong machine and a card picking and transporting system, a card loading component, a card loading method and a mahjong card sorting method thereof. [Background technology]

[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. The patent document with publication number CN105363195A discloses a card feeding device for a mahjong machine. By reasonably adjusting and designing the positions of the card outlet and the card inlet of the card feeding device, the card feeding channel is curved in an arc shape, so that the mahjong cards sent by the card feeding device to the card receiving block of the card pushing device and the mahjong cards pushed out by the card pushing device are neat and tidy with less resistance.

[0009] The patent document with the publication number CN105413161A discloses a card loading drive mechanism, a card loading assembly and a mahjong machine. The card loading drive mechanism of the mahjong machine includes a card loading bracket, a card storage slot, a card loading guide rail, a card loading push head and a steel wire rope. A rolling member is arranged at a position where the steel wire rope is close to the card loading guide rail and / or the card storage slot. The rolling member is rotatably mounted on the card loading guide rail or the card loading bracket. The portion of the steel wire rope in the card storage slot is in rolling contact with a plurality of rolling members and maintains a gap with the side wall of the card loading guide rail and / or the card storage slot. The scheme replaces the sliding friction of the steel wire rope in the prior art with the rolling friction of the steel wire rope, so that the friction resistance of the steel wire rope operation is greatly reduced, and the sliding friction contact between the portion of the steel wire rope in the card storage slot and the arc-shaped curved side wall of the card loading guide rail and / or the card storage slot is avoided to affect the service life and operation stability of the steel wire rope.

[0010] Patent documents such as CN106075897A and CN106215413A disclose a mahjong machine and a card loading component and a card loading drive mechanism. The card loading component includes a card loading bracket, which is provided with a card storage slot, a first card loading pusher and a second card loading pusher. The card storage slot is provided with a notch on the inner side wall at a middle position, and the card storage slot is connected with the reversing slot through the notch. The first card loading pusher is driven by the card loading drive mechanism to move from the card inlet of the card storage slot to the vicinity of the notch and then return. The second card loading pusher is driven by the card loading drive mechanism to move from the card outlet of the card storage slot to the reversing slot and then return. The card loading drive mechanism includes a first card loading push rod and a second card loading push rod which reciprocate and cooperate with each other. The first card loading pusher is arranged on the first card loading pusher, and the second card loading pusher is arranged on the second card loading pusher. This solution adopts the method of two card-loading push rods relaying the card-loading, which completely avoids the defects of the prior art such as large resistance between the card-loading push head and the guide rail and large noise during chain operation.

[0011] However, the above-mentioned sloped mahjong machine in the prior art, although repeatedly developed and improved by the inventor, has not yet completely overcome the following technical problems:

[0012] 1. In the prior art, the card feeding device and the card raising component are arranged on the inner side of the card storage slot, and the card raising component in one group of card picking and transporting systems is arranged on the inner side of the card feeding device in another group of card picking and transporting systems, so that adjacent card picking and transporting systems are staggered to extend the length of the card storage slot. However, the number of mahjong tiles that can be stored is still limited, especially for large mahjong tiles.

[0013] 2. Because adjacent card picking and transporting systems are staggered with each other, it is inevitable that adjacent card feeding devices and card lifting components overlap each other, which increases the height of the entire mahjong machine.

[0014] 3. Because the adjacent card picking and transporting systems are staggered, the card lifting components and the card storage slots cannot be overlapped and the length of the card storage slots is limited, so the location of the card lifting ports of the adjacent card picking and transporting systems is greatly restricted, affecting the comfort of using the mahjong machine. For example, if a 85cm square mahjong machine uses 48mm mahjong tiles, Figure 1 As shown, the four rows of mahjong tiles directly raised from the four-sided raising openings 111 on the table 11 are arranged in a windmill shape, and the distance between the two opposite rows of mahjong tiles is 35 cm. This results in a very small area on the left hand side where the player is accustomed to placing the tiles (that is, the distance between the mahjong tile wall and the edge of the table frame is too small) and the player cannot place the tiles. The player needs to move the mahjong tile wall to empty the tile area, which affects the comfort of use.

[0015] 4. Because adjacent card picking and transporting systems are staggered with each other, the arc curvature of the card storage slot is small (that is, the card input direction and the card output direction of the card storage slot are arranged at an acute angle) and the shape is irregular. Therefore, the card loading drive mechanism that drives the card loading push head in the card storage slot to move has a complex structure, high manufacturing precision requirements, reliability is limited by the structure, and the manufacturing cost and maintenance cost are high.

[0016] The patent document with the publication number CN106166379A discloses a ring-shaped card-pushing device of an automatic mahjong machine and a mahjong machine. The device comprises a motor, a turntable, a card-pushing block assembly, a ring-shaped upright track, a base and a ring-shaped card-blocking side plate of the base, the ring-shaped upright track is arranged on the surface of the base, the base, the ring-shaped upright track and the ring-shaped card-blocking side plate of the base form a mahjong card-pushing slot, the mahjong card-pushing slot is provided with a mahjong card inlet and a mahjong card outlet, a card-pushing block assembly is arranged on the ring-shaped upright track, the inner side of the card-pushing block assembly has a card slot, the card-pushing block assembly is movably plugged into the ring-shaped upright track through the card slot, the part of the card-pushing block assembly built into the mahjong card-pushing slot has a card-pushing arm for card-pushing transmission, the motor is mounted on the base, and the motor is connected to the turntable for transmission, and the turntable has a driving part for driving the card-pushing block assembly to push cards in the mahjong card slot. In this structure, the card pushing block is plugged into the annular vertical track and slides to push the cards. The annular vertical track is composed of arc segments and straight segments. The card pushing block is driven by a turntable to move back and forth in the card pushing slot. In this way, the friction resistance between the card pushing block and the track is large, the service life of the components is low, the movement path of the card pushing block is irregular, the structure of the card pushing block driven by the turntable is complex, the manufacturing precision requirements are high, the reliability is limited by the structure, and the manufacturing cost and the use and maintenance cost are high. In addition, because the card pushing device must cooperate with the linear card bearing platform of the stacking device and the linear card lifting slot of the card lifting device, and the card pushing block assembly moving along the annular vertical track is relatively large, its annular vertical track must be composed of arc segments and straight segments, otherwise it will cause the movement of mahjong tiles to be stuck or even stuck. Therefore, in this structure, when the card pushing block pushes the mahjong tiles out of the mahjong slot of the card pushing device, it must return along the original path.

[0017] The card loading assembly disclosed in the series of patent application documents such as publication number CN107233724 includes a card loading bracket, a card loading bracket is provided with a card storage slot for storing multiple mahjong tiles and a card loading pusher for pushing mahjong tiles out of the card storage slot, the card storage slot is curved in an arc shape and the bending angle is greater than 180°, the card inlet direction of the card inlet on the card storage slot and the card outlet direction of the card outlet are at an angle of 45° to 90°, and the card loading pusher is driven by a card loading drive mechanism to move from the card inlet of the card storage slot to the card outlet of the card storage slot and then return to the card inlet of the card storage slot. The card loading pusher can move back and forth along the card storage slot or unidirectionally cyclically. The card loading drive mechanism is a card loading push rod rotating around a fixed point, the card loading pusher is installed on the card loading push rod, and the card loading push rod is connected to the card loading motor by transmission. The card loading drive mechanism adopts a single push rod structure. The rotation center of the card loading push rod is concentric with the arc bending center of the card storage slot. The card pushing head located in the card storage slot does not need a track or contact with the inner wall of the card storage slot. Although the friction resistance of the card pushing head movement is reduced, the driving force part and the thrust part of the card loading push rod are respectively located at both ends, and the distance between the two is relatively long, resulting in a large load on the motor driving the card loading push rod and a short service life of the card loading push rod. [Summary of the invention]

[0069] like Figure 2-4 , Fig.13 and Fig.16 The mahjong machine shown in the figure includes a central control disk assembly 1 located in the center of the bottom plate of the frame, a shuffling plate 2 and a card scraper, and four sets of card picking and transporting systems are arranged around the shuffling plate. The card picking and transporting systems include a card feeding device 3 for picking up mahjong tiles from the shuffling plate one by one and sending them out, a card pushing device 4 for stacking mahjong tiles into a pile and pushing them out, and a ramp card discharging device for sending the arranged mahjong tiles onto the mahjong machine table along the ramp, and the ramp card discharging device includes a card loading assembly 5 and a card lifting assembly 6.

[0070] The card feeding device 3 comprises a card feeding box, a card feeding channel for transferring mahjong cards is arranged in the card feeding box, a card suction wheel is arranged at the card inlet of the card feeding channel, and a conveyor belt driven by a card feeding motor is arranged in the card feeding channel.

[0071] The card delivery channel can be a traditional straight channel, but an arc-shaped card delivery channel can also be selected for the purpose of optimizing the structural layout. In order to ensure the reliability of mahjong card delivery, the height of the card delivery channel is not lower than the height of the card delivery channel. The specific structure of the card delivery device can be found in the patent document with publication number CN105413161A.

[0072] In one embodiment, the card pushing device 4 is capable of realizing the stacking and pushing functions (stack two or more mahjong tiles into one pile and push out), including a card pushing head and a card receiving platform. The specific structure of the card pushing device can refer to the patent documents such as publication number CN201906453U, CN201949619U, CN103861280A and CN204699375U, CN101987247. In general, the card pushing device with the stacking function includes a head box, a card pushing motor is installed on the head box, a transmission mechanism is provided in the head box, a card pushing head and a card receiving platform are provided outside the head box, the card pushing motor drives the card receiving platform to move up and down through the transmission mechanism to realize the stacking of mahjong tiles, and the card pushing motor drives the card pushing head to move horizontally through the transmission mechanism to realize the push out of the stacked mahjong tiles. Of course, the card pushing device can also be other mechanisms that can realize the card receiving platform carrying a pile of mahjong tiles and the card pushing head pushing out a pile of mahjong tiles. The head box is equipped with a counting detection device for detecting the number of times and / or the number of pushed cards. A card retaining frame is provided near the card receiving platform. The card outlet of the card feeding device and the card retaining frame are respectively located on two opposite sides of the card receiving platform. One side is provided with a card pushing head, and the other side is an exit for the card pushing head to push mahjong cards out of the card receiving platform. The card feeding detection device for detecting whether the card outlet of the card feeding device has sent mahjong cards to the card receiving platform can be provided on the card retaining frame, but is preferably provided on the side of the card receiving platform where the card pushing head is provided to improve the detection accuracy and reliability. The card feeding detection device can be installed on the extension of the card retaining frame or on the card pushing head.

[0073] In another embodiment, the stacking device for stacking mahjong tiles into a pile and the pushing device for pushing the mahjong tiles stacked into a pile into the tile storage slot are two relatively independent devices. In order to save the cost of the motor, the card stacking device and the card feeding device can be combined. For example, the structures disclosed in patent documents such as the publication numbers CN105903186A, CN205699378U, CN205699375U, CN205832557U, and CN107233724 series applications are as follows: a card stacking device for stacking mahjong tiles into a pile, comprising a card-receiving conveyor belt installed on a card-receiving bracket, the conveying direction of the card-receiving conveyor belt is basically consistent with the conveying direction of the card-feeding conveyor belt, the card-receiving conveyor belt is arranged below the card outlet of the card-feeding device, the card-receiving surface of the card-receiving conveyor belt is lower than the card outlet of the card-feeding device by about the thickness of a mahjong tile, a card baffle and a side baffle are arranged near the card-receiving conveyor belt, the card outlet and the card baffle of the card-feeding device are respectively located on two opposite sides of the card-receiving conveyor belt, and the side baffle and the mahjong card ejection outlet are respectively located on the other opposite sides of the card-receiving conveyor belt. The card delivery detection device for detecting whether the card delivery device has delivered mahjong tiles to the card conveyor belt can be arranged on the card blocking member, but is preferably arranged on the side blocking member to improve the detection accuracy and reliability.

[0074] The stacking principle of the stacking device is as follows: the first mahjong tile is sent out of the card delivery channel. Because the card receiving conveyor belt is lower than the card delivery conveyor belt, when the first mahjong tile is sent out of the card delivery channel and exceeds one-half, the front end of the first mahjong tile falls on the card receiving conveyor belt under its own gravity. 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 on the card receiving conveyor belt and is blocked by the card blocking member and cannot move, the second mahjong tile continues to move in the direction of the card receiving conveyor belt. Since the height difference between the card receiving conveyor belt and the card delivery conveyor belt is greater than the thickness of the mahjong tile, the second mahjong tile is directly stacked on the first mahjong tile to achieve the stacking of one mahjong tile. The stacking principle of three mahjong tiles is similar.

[0075] There are many implementations for the power source of the card-carrying conveyor belt: the first implementation is that the card-carrying conveyor belt and the card-delivering conveyor belt are the same conveyor belt, and multiple conveyor belt wheels are arranged under the card-discharging wheel of the card-delivering device to wind the conveyor belt to form the card-carrying conveyor belt, so that the card-carrying conveyor belt and the card-delivering conveyor belt rotate at the same speed, and are both driven by the card-delivering motor. The second implementation is that the card-carrying conveyor belt and the card-delivering conveyor belt are two independently wound conveyor belts, and the card-carrying conveyor belt is connected to the conveyor belt wheel of the card-delivering conveyor belt or the card-delivering motor through a transmission component. The third implementation is that the card-carrying conveyor belt and the card-delivering conveyor belt are two independently wound conveyor belts, and the power of the card-carrying conveyor belt comes from the shuffling plate, so that the position and structure of the stacking device are more flexible.

[0076] There are many ways to set up the card-holding bracket used for installing the card-holding conveyor belt: the card-holding bracket can be integrally manufactured or fixedly connected with the inner shell and / or outer shell of the card box of the card feeding device; or, the card-holding bracket is independently fixed on the bottom plate of the mahjong machine; further, the card-holding bracket can also be integrally manufactured or fixedly connected with the card-loading bracket provided with a card storage slot.

[0077] The pusher device for pushing the mahjong tiles stacked into a pile into the storage slot can be an independent pusher device, such as only the pusher head and its driving mechanism in the above-mentioned embodiment. In a preferred embodiment, the pusher head in the upper card assembly is used to realize this function.

[0078] The card loading component comprises a card loading bracket 501, the card loading bracket 501 is provided with a card storage slot 502 for storing multiple piles of mahjong tiles and a card loading pusher 505 for pushing mahjong tiles out of the card storage slot 502, the card storage slot 502 is curved in an arc shape and the bending angle is greater than 180°, the card input direction of the card input port 5021 on the card storage slot 502 and the card output direction of the card output port 5022 are at an angle of 45° to 90°, and the card loading pusher 505 is driven by a card loading driving mechanism to move from the card input port of the card storage slot 502 to the card output port of the card storage slot 502 and then return to the card input port of the card storage slot 502. The card loading pusher 505 can move back and forth along the card storage slot, or can move in a single direction in a circular motion.

[0079] The specific structure of the card-lifting component can be found in patent documents with publication numbers CN201906453U, CN201949619U, CN102133480A, CN103861280A, CN105413161A and CN204699375U. Generally speaking, one party's card-lifting component 6 includes a card-lifting bracket, a card-lifting support plate 601 and a card-lifting motor. The card-lifting bracket is provided with a card-lifting slot, the card-lifting support plate is located on the upper part of the card-lifting slot, and one end of the card-lifting support plate (i.e., the card outlet end) is installed on the card-lifting slot, and the other end of the card-lifting support plate (i.e., the card inlet end) can move and is driven up and down by the card-lifting motor through a transmission mechanism such as a cam or a card-lifting rocker arm. The card-lifting bracket is also provided with a sensor for detecting the position of the card-lifting support plate, such as two upper and lower Hall elements or photocells. Figure 3 As shown, a card raising opening 111 matching the card raising support plate 601 is provided on the table top 1 of the mahjong machine.

[0080] The mahjong machine of the present invention has four sets of card picking and transporting systems which are independently arranged and not staggered with each other, that is, the card lifting component is arranged on the inner side of the card feeding device in the same set of card picking and transporting systems and the two are directly adjacent inside and outside. In the same set of card picking and transporting systems: the card lifting component 6 is arranged on the inner side of the card feeding device 3, the card lifting component 6 and the card feeding device 3 are arranged outside the arc-shaped bend of the card storage slot 502, and the card loading driving mechanism of the card loading pushing head 505 is arranged inside the arc-shaped bend of the card storage slot 502. The card-discharging direction of the card device 3 and the card-feeding direction of the card-raising component 6 form an angle of 135° to 180°, a card-pushing device is arranged at the card-discharging port of the card-feeding device 3, the card-pushing direction of the card-pushing device 4 and the card-discharging direction of the card-feeding device 3 form an angle of 80° to 100°, the card-feeding direction of the card storage slot 502 in the card-loading component 5 and the card-pushing direction of the card-pushing device 4 form an angle of 0° to 10°, and the card-discharging direction of the card storage slot 502 in the card-loading component 5 and the card-feeding direction of the card-raising component 6 form an angle of 0° to 5°.

[0081] In this way, the four sets of card picking and transporting systems are independently arranged without being staggered with each other, which has the following advantages:

[0082] 1. The card feeding device and the card lifting assembly in the same group of card picking and transporting systems are directly adjacent to each other inside and outside, so that the card storage slot is curved in a large angle, which extends the length of the card storage slot and increases the storage quantity of mahjong tiles in the card storage slot.

[0083] 2. The card lifting component and the card feeding device in the same card picking and transporting system are arranged outside the arc-shaped bend of the card storage slot, and the card loading drive mechanism of the card loading push head is arranged inside the arc-shaped bend of the card storage slot, so that there is no vertical overlap between the card loading component and the card feeding device, and there is no vertical overlap between the card feeding device and the card lifting component, or there is only a small amount of overlap between the card outlet end of the card lifting component and the card feeding device, thereby avoiding the problem in the prior art that the vertical overlap of related device components significantly increases the height of the whole mahjong machine due to the staggered arrangement of adjacent card picking and transporting systems. Compared with the machine in the prior art in which the card storage slot is stacked on the card feeding device, the overall height of the machine can be reduced accordingly.

[0084] 3. The card lifting assembly and card feeding device in the same group of card picking and transporting systems are arranged outside the arc-shaped curve of the card storage slot, and the card loading drive mechanism of the card loading push head is arranged inside the arc-shaped curve of the card storage slot, so that the arc-shaped curve of the card storage slot is closer to a circular arc. In this way, the resistance of the card loading drive mechanism to drive the card loading push head to move in the card storage slot to push the cards is smaller, and the force to be applied in each stage of the movement is more uniform. In this way, the motor load of the card loading drive mechanism is smaller, the transmission structure is simpler, the reliability is better, and the manufacturing cost and the use and maintenance cost are reduced.

[0085] 4. Adjacent card picking and transporting systems are independent of each other and are not staggered, so that the card raising port of the mahjong table is no longer restricted by the position and length of the card storage slot. In this way, the position of the card raising port can be moved inward, so that the setting space of the card loading component is larger, the arc radius of the card storage slot can be larger, and the card storage slot is longer and the number of stored cards is larger. Take the 85cm square mahjong machine using the structure of the present invention as an example, using 48mm mahjong tiles, such as Figure 2 , Figure 4 As shown, the four rows of mahjong tiles directly raised from the four-sided raising openings 111 onto the table 11 are arranged in a windmill shape, and the distance between the two opposite rows of mahjong tiles (i.e., the two opposite raising openings) is 30.5 cm. According to the size of the mahjong tiles, this distance can be reduced to 30.5±1 cm. In this way, the area on the left hand side where the player is accustomed to placing the tiles will be larger and easier to place the tiles. The player does not need to deliberately move the mahjong tiles to empty the tile area, and the user experience and comfort are better.

[0086] In addition, the four sets of card picking and handling systems are set up independently, and a large space can be left between two adjacent card loading components. In this way, the control mainboard, transformer and large plate motor originally placed in the electrical box under the bottom plate of the mahjong machine can be placed in the gap between the two card loading components outside the shuffling large plate, which can make the electrical box smaller and thinner. In the central control structure scheme using the flat door structure, the electrical box can be removed, which greatly reduces the height and manufacturing cost of the mahjong machine host, making the electrical box in the four-legged mahjong machine almost invisible. The smaller and thinner electrical box makes the user experience and comfort better.

[0087] The card-loading drive mechanism can be in various forms, such as a wire rope traction mechanism, a chain traction mechanism, a lever transmission mechanism, a gear transmission mechanism, and a cam transmission mechanism, etc.:

[0088] For example, the turntable and the push card head active connection structure disclosed in the series of patent application documents such as publication number CN106166379, in which the push card block is plugged into the annular vertical track and slides to push the cards, and the annular vertical track is composed of arc segments and straight segments, and the push card block is driven by the turntable to move back and forth in the push card slot. In this way, the friction resistance between the push card block and the track is large, the service life of the components is low, the movement path of the push card block is irregular, the structure of the push card block driven by the turntable is complex, the manufacturing precision requirement is high, the reliability is limited by the structure, and the manufacturing cost and the use and maintenance cost are high. In addition, because the push card device must cooperate with the straight card support platform of the stacking device and the straight card lifting slot of the lifting device, and the push card block assembly moving along the annular vertical track is relatively large, its annular vertical track must be composed of arc segments and straight segments, otherwise it will cause the mahjong cards to move and even get stuck. Therefore, in this structure, the push card block must return along the original path when pushing the mahjong cards out of the mahjong slot of the push card device.

[0089] For example, the card loading assembly disclosed in the series of patent application documents such as publication number CN107233724 includes a card loading bracket, a card loading bracket is provided with a card storage slot for storing multiple mahjong tiles and a card loading pusher for pushing the mahjong tiles out of the card storage slot, the card storage slot is curved in an arc shape and the bending angle is greater than 180°, the card inlet direction of the card inlet on the card storage slot and the card outlet direction of the card outlet are at an angle of 45° to 90°, and the card loading pusher is driven by a card loading drive mechanism to move from the card inlet of the card storage slot to the card outlet of the card storage slot and then return to the card inlet of the card storage slot. The card loading pusher can be moved back and forth along the card storage slot, or it can be moved in a single direction. The card loading drive mechanism is a card loading push rod rotating around a fixed point, the card loading pusher is installed on the card loading push rod, and the card loading push rod is connected to the card loading motor by transmission. The card loading drive mechanism adopts a single push rod structure. The rotation center of the card loading push rod is concentric with the arc bending center of the card storage slot. The card pushing head located in the card storage slot does not need a track or contact with the inner wall of the card storage slot. Although the friction resistance of the card pushing head movement is reduced, the driving force part and the thrust part of the card loading push rod are respectively located at both ends, and the distance between the two is relatively long, resulting in a large load on the motor driving the card loading push rod and a short service life of the card loading push rod.

[0090] In the present invention, the card loading drive mechanism adopts a chain traction mechanism.

[0091] like Figure 5 , Fig.14 The ramp card discharging device shown comprises a card raising component and a card loading component, wherein the card loading component comprises a card loading bracket 501, the card loading bracket 501 is provided with a card storage slot 502 for storing multiple mahjong tiles and a card loading pusher 505 for pushing mahjong tiles out of the card storage slot 502, the card storage slot 502 is curved in an arc shape and the bending angle is greater than 180°, the card input direction of the card input port 5021 on the card storage slot 502 and the card output direction of the card output port 5022 are at an angle of 45° to 90°, and the card loading pusher 505 is driven by a card loading drive mechanism to move from the card input port of the card storage slot 502 to the card output port of the card storage slot 502 and then return to the card input port of the card storage slot 502. The card loading pusher 505 can move back and forth along the card storage slot or can move in a single direction in a circular motion. The card loading drive mechanism includes a card loading chain 503 and a card loading sprocket, and a card loading push head 505 is installed on the card loading chain 503. The chain length of the card loading chain 503 is greater than the total length of the mahjong tiles stored in the card storage slot, and the running track of the card loading chain 503 matches the running track of the mahjong tiles in the card storage slot. The card loading sprocket is connected to the card loading motor in a transmission manner.

[0092] The card loading chain 503 runs along the chain track fixed on the card loading bracket 501. The chain track can be formed by a plurality of tensioning sprockets or transition sprockets, or by a combination of a plurality of transition sprockets and track plates. However, it is preferred that the chain track is formed by a fixed chain track groove 5034, so that the running track of the card loading chain 503 can be more consistent with the running track of the mahjong tiles in the card storage slot. In order to reduce the running friction between the chain and the track groove, the inner wall of the chain track groove 5034 can be made of a material with a smooth and wear-resistant surface, such as polyformaldehyde, polytetrafluoroethylene, etc. For example, it can be fixed on the card loading bracket in the form of a chain track seat made of a smooth and wear-resistant surface. Further preferably, the card loading chain 503 and the chain track groove 5034 are in rolling contact to reduce the running resistance. For example, the rollers on the chain links of the card loading chain 503 are in rolling contact with the chain track groove 5034, such as Fig. 9 , Fig.12 As shown, the cross section of the chain track groove 5034 is T-shaped, and the two inner side walls of the chain track groove 5034 extend convex strips to roll with the rollers of the card chain 503. In other embodiments, a chain with a roller outer diameter greater than the width of the chain plate can also be used. In a further preferred embodiment, the roller of the card chain 503 is a structure with an annular groove on the circumferential surface, and the annular groove cooperates with the convex strips extending from the two inner side walls of the chain track groove 5034, and the upper and lower limit is realized while rolling contact, which can not only limit the moving direction and the upper and lower position of the card chain to avoid twisting and blocking, but also avoid the friction contact between the bottom of the chain and the bottom of the chain track groove to increase the running resistance. For the card chain 503 being an open-loop chain, it is preferred to adopt the above-mentioned upper and lower limit structures to reduce the chain movement resistance and avoid running failures. For the chain track groove 5034 with a T-shaped cross section, the chain track seat 5033 can be manufactured by the inner side wall or the outer side wall respectively and then assembled and fixed as one. A plurality of notches are provided on the chain track groove 5034 for arranging a sprocket wheel. The chain track groove 5034 and the chain track seat 5033 are annular as a whole, so that the card chain 503 circulates.

[0093] like Figure 5 In the first embodiment shown, the card loading chain 503 is installed above the inner side of the card storage slot 502, and the upper part of the card loading pusher 505 extends to the inner side of the card storage slot 502 and is fixed on the link of the card loading chain 503. This structure is simple and reasonable, and is convenient for modification compared to existing equipment.

[0094] In this embodiment, the installation methods of the card chain can be as follows:

[0095] 1. If Figure 6 , Figure 7As shown, the card loading chain 503 is a closed-loop chain, which is connected end to end as a whole and only requires an actively driven card loading sprocket, the second sprocket 5032. In order to tension the card loading chain 503, a tensioning sprocket, the first sprocket 5031, can be provided; in this way, the card loading chain 503 can drive the card loading push head 505 to move back and forth or move in a single direction along the card storage slot.

[0096] 2. If Figure 8 , Fig.10 As shown, the card loading chain 503 is an open-loop chain, which is not connected at the beginning and the end, but adopts a double card loading sprocket structure - the first sprocket 5031 and the second sprocket 5032 are both connected to the card loading motor 506 through gears, so that the card loading chain 503 can also drive the card loading push head 505 to move back and forth or move in a single direction along the card storage slot.

[0097] 3. Fig.11 , Fig.12 As shown, the card loading chain 503 is an open-loop chain, which is not connected at the beginning and the end, and only uses an actively driven card loading sprocket - the second sprocket 5032. The first sprocket 5031 is a tensioning sprocket for tensioning the card loading chain 503, so that the card loading chain 503 can only drive the card loading push head 505 to move back and forth along the card storage slot.

[0098] In the above-mentioned open-loop chain, the card loading push head is preferably installed in the middle position of the card loading chain, so that the running resistance of pushing forward and pulling backward is small.

[0099] like Fig.13 , Fig.14 In the second embodiment shown, the card loading chain 503 is installed under the card storage slot 502, and the lower part of the card loading pusher 505 passes downward through the slot at the bottom of the card storage slot 502 and is fixed on the chain link of the card loading chain 503. The installation method of the card loading chain in this embodiment can be the same as that of the previous embodiment. The chain track seat 5033 with a chain track groove 5034 is installed at the bottom of the card storage slot 502. In this way, the installation of the card loading chain is sufficient, and the thrust of the card loading pusher is greater and the operation is stable. However, this embodiment requires the use of a card receiving platform or a card receiving conveyor belt that cooperates with the chain drive, such as the card pushing device of the flap structure card receiving platform disclosed in the patent document with publication number CN202446788U. That is to say, the card receiving table outside the card outlet of the card feeding device that receives the mahjong tiles is in the form of a card receiving plate that can be flipped open along one side. The card receiving plate serves as a part or an extension of the card receiving table or the card receiving conveyor belt. When the card feeding device delivers the mahjong tiles to the card receiving table or the card receiving conveyor belt, the card receiving plate covers the chain track groove to prevent the mahjong tiles from falling into the groove and causing malfunctions. When the card pushing head is needed to push the cards, the card receiving plate flips open to one side to allow the card pushing head to pass through.

[0100] In the third embodiment of the present invention, the card loading chain 503 is installed at the lower inner side or the middle of the inner side of the card storage slot 502, and the inner side wall of the card storage slot 502 is provided with an opening for the card loading pusher 505 in the card storage slot to extend to the inner side of the card storage slot 502 and be fixed on the chain link of the card loading chain 503. The installation of the card loading chain is sufficient in this way, and the thrust of the card loading pusher is larger and the operation is stable. However, this embodiment needs to slot the inner side wall of the card storage slot, or needs to make all or part of the inner side wall of the card storage slot separately and then assemble it on the card loading bracket, or it can also be that the inner side wall of the card storage slot is first fixed or integrally formed on the cover of the card storage slot, and then the cover is fixed on the card loading bracket. The card loading chain installation mode of this embodiment can be the same as the previous embodiment. The chain track seat 5033 with the chain track groove 5034 is installed on the inner side of the card storage slot 502 or is integrally formed with the card loading bracket.

[0101] In other embodiments, the card loading pusher can move along the track, and the card loading chain is movably connected to the card loading pusher, for example, by a pin and a waist-shaped hole to achieve movably connected and thrust transmission, and the track can be set on the inner side wall, outer side wall or bottom of the card storage slot. The card loading chain installation method can be the same as the above embodiment. The card loading chain here can also be replaced by a wire rope, and correspondingly, the card loading sprocket is replaced by a wire rope drive wheel.

[0102] In other embodiments, the card loading chain and its driving mechanism may be installed outside the card storage slot. The installation method of the card loading chain may be the same as that of the above embodiment.

[0103] The card storage slot can be in an arc shape as a whole, or can be composed of several arc slot segments. In order to further extend the length of the card storage slot, Fig.16 As shown, it is preferably composed of a plurality of straight groove segments 5023 and a plurality of arc groove segments 5024.

[0104] In addition, if conditions permit, it is preferred to use a card storage slot 502 that is in an arc shape as a whole, and the card storage slot 502 is a whole arc. In this way, because the card pushing head 505 does not need to change the card pushing position of the mahjong tiles at the card inlet and card outlet of the card storage slot, the card pushing head 505 can still have more contact position options and a larger contact area with the mahjong tiles when rotating around the fixed point. Whether it is pushing the mahjong tiles on the card receiving platform or the card receiving conveyor belt or pushing the mahjong tiles in the card storage slot, a good card pushing effect can be guaranteed, and there will be no problem of mahjong tiles being stuck or unable to be pushed into the card storage slot. Of course, the card storage slot 502 that is in an arc shape as a whole is more suitable for the card loading component using the staged card loading method, because the length of the card storage slot of the staged card loading method can be shorter.

[0105] In order to reduce the friction resistance between mahjong tiles and the bottom of the card storage slot without significantly increasing the cost, the bottom of the card storage slot is provided with a card storage slot bottom patch, and the card storage slot bottom patch is preferably made of a material with a smooth surface and wear resistance, such as polyoxymethylene, polytetrafluoroethylene, etc. The card storage slot bottom patch is installed in the card storage slot of the upper card bracket as an independent component, and the upper card bracket is made of a material with poor performance and low price, which can not only meet the use needs, but also reduce the machine manufacturing cost. The card storage slot bottom patch is preferably positioned by cooperating with the upper card bracket through multiple buckles and locked and fixed by fasteners to facilitate installation. Similarly, in order to reduce the friction resistance between mahjong tiles and the inner side wall and outer side wall (especially the arc-shaped curved section side wall) of the card storage slot without significantly increasing the cost, the inner side wall and / or outer side wall of the card storage slot are partially or entirely provided with side wall patches, and the side wall patches are preferably made of a material with a smooth surface and wear resistance, such as polyoxymethylene, polytetrafluoroethylene, etc. In this embodiment, the patches on the bottom, inner side wall and outer side wall of the card storage slot are made of smooth and wear-resistant materials in one piece.

[0106] The card storage slot can be made into a slope with a gentle slope from the card inlet to the card outlet, but this will increase the pushing resistance of the card pusher. The present invention is preferably that most of the card storage slot is horizontally arranged, and a card-discharging slope for lifting mahjong tiles is provided near the card outlet of the card storage slot, so that not only the mahjong tiles near the card outlet in the card storage slot are effectively prevented from falling back to the shuffling plate during the card pushing process of the card pushing device, but also the card-discharging resistance of the card pusher will not be increased too much. In addition, the card storage slot is provided with a slope, which can also extend the length of the card lifting support plate in the card lifting assembly to a certain extent, slow down the inclination slope of the card lifting support plate, and thus reduce the card-discharging resistance. The card-discharging slope can be formed at the bottom of the card storage slot, but is preferably arranged on the bottom patch of the card storage slot, that is, most of the bottom patch of the card storage slot is horizontally arranged, and the bottom patch of the card storage slot is formed with a card-discharging slope that can lift mahjong tiles near the card outlet of the card storage slot. The patch at the bottom of the card storage slot is formed with a card entry slope for mahjong tiles to enter at the card entry opening of the card storage slot. In order to prevent the mahjong tiles in the card storage slot from being arched or jumping during the card pushing process of the card pushing device, a cover for limiting the card storage height of the card storage slot is installed above the card storage slot on the card support 501, and the cover covers part or all of the top of the card storage slot. The inner side wall and / or outer side wall of the card storage slot can be integrally formed with the card support, or can be independently manufactured and then fixed to the card support to form a whole, or can be integrally formed or fixedly connected with the cover of the card storage slot. The inner side wall and / or outer side wall of the card storage slot are arranged on the cover, and the width of the card storage slot can be conveniently changed by replacing the cover to be suitable for mahjong tiles of different sizes.

[0107] In order to prevent the mahjong tiles lifted onto the mahjong machine table from shifting up and down, the horizontally movable loading card pushing head has multiple card pushing positions, which respectively contact two mahjong tiles stacked up and down in the same pile, wherein the card pushing position contacting the lower mahjong tiles protrudes from the card pushing position contacting the upper mahjong tiles. In this way, when the loading card pushing head pushes multiple piles of mahjong tiles to move horizontally, the mahjong tiles on the upper layer lag behind the mahjong tiles on the lower layer. When the loading card pushing head pushes the last pile of mahjong tiles onto the inclined card lifting support plate, the mahjong tiles on the upper layer are flush with the mahjong tiles on the lower layer.

[0108] The card retaining frame can be fixedly connected with the card loading bracket or formed in one piece. The card feeding box, the card loading bracket, and the card lifting bracket in the four-way card picking and handling system can be fixedly connected or several combinations can be formed in one piece. In this embodiment, the card feeding box and the card lifting bracket in the four-way card picking and handling system adopt an annular housing formed in one piece, which is convenient to assemble and has a simple and reliable structure.

[0109] In the present invention, the card loading pusher 505 can move back and forth along the card storage slot, or can move in a single direction. If the card loading pusher moves in a single direction, it must pass through the card loading slot inlet position of the card loading assembly 6. Figure 5 , Fig.14 As shown, an avoidance opening 5023 is opened on the outer wall of the card raising slot for the card loading push head to pass through. Because in the illustrated embodiment, the outer wall of the card inlet of the card raising slot is formed by the card loading bracket 501, the avoidance opening is actually formed on the card loading bracket.

[0110] The card-loading pusher can be unidirectionally cyclically rotated, so that the sloped card-discharging mahjong machine of the present invention can realize the staged card loading: in the existing sloped card-discharging mahjong machine, mahjong tiles are shuffled by the shuffling plate and then transported to the card-pushing device by the card-feeding device, and the card-pushing device pushes the mahjong tiles stacked into a pile into the sloped card-discharging device, and the mahjong tiles are arranged into a row of many piles in the sloped card-discharging device, and after the designated number of piles is arranged, the sloped card-discharging device pushes all of them onto the desktop of the corresponding party at one time. In this way, according to different playing habits, the existing mahjong machine arranges a row of mahjong tiles arranged in piles on each of the four sides of its desktop (for example, 18 piles on each of the four sides), and when playing cards, the player manually grabs the cards, arranges them, and stands the grabbed cards upright in order with the cards facing themselves (for example, 13 cards on each of the four sides, and one more card for the dealer). In the present invention, since the card-loading pusher can realize unidirectional circular rotation, the card-loading method can be realized in stages. The card-loading method is as follows: after the card-pushing device pushes six and a half piles or thirteen mahjong tiles into the card storage slot of the ramp card-discharging device, the card-loading pusher enters and stays in the card storage slot. In this way, there are six and a half piles or thirteen mahjong tiles before the card-loading pusher, and the remaining mahjong tiles are pushed in by the card-pushing device after the card-loading pusher, so that the card-loading pusher is clamped between the front and rear rows of mahjong tiles; when the mahjong machine receives the first card-loading signal, the card-lifting support plate of the card-lifting device descends, and the card-loading pusher first pushes the card in front of it Six and a half or thirteen mahjong tiles push the card lifting plate, which is lifted to put the mahjong tiles on the table, and the card lifting pusher moves to the outside of the entrance of the storage slot through the opening on the side wall of the lifting slot; after the player takes the six and a half or thirteen mahjong tiles on the table, the mahjong machine receives the second card lifting signal, and the card lifting plate is lowered again, and the card lifting pusher enters the storage slot again to push the remaining mahjong tiles on the card lifting plate, and the card lifting plate is lifted to put the mahjong tiles on the table, and the card lifting pusher moves to the outside of the entrance of the storage slot through the avoidance opening on the side wall of the lifting slot again, waiting for the next card lifting. In this way, the staged lifting is adopted, and the player can start playing the six and a half or thirteen mahjong tiles that are put on for the first time are erected, which saves the process of manual card separation and arrangement, and the player's operation is simpler and more convenient, and the entertainment experience is better. Furthermore, by loading the tiles in stages, the card feeding device and the card pushing device can continue to feed the mahjong tiles into the tile storage slot for storage while six and a half or thirteen tiles are loaded for the first time. In this way, the tile storage slot does not need to store all the mahjong tiles required for one side (for example, 18 tiles for each side) at one time, but only needs to store the number of mahjong tiles loaded at one time. Therefore, the length of the tile storage slot can be greatly shortened, thereby making the layout of the mahjong machine host more flexible and compact, the size of the mahjong machine smaller, or larger mahjong tiles can be used on the same size machine.

[0111] The method for arranging mahjong tiles of the mahjong machine using the card pushing device 4 capable of stacking and pushing tiles is as follows:

[0112] A central control panel assembly, a shuffling plate 2 and a card scraper are arranged in the center of the frame bottom plate, and four groups of card picking and transporting systems are arranged around the shuffling plate. The card picking and transporting system includes a card feeding device 3 for picking up mahjong tiles from the shuffling plate and sending them out, a card pushing device 4 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 the slope. The ramp card discharging device includes a card loading assembly 5 and a card raising assembly 6; the card raising assembly is arranged on the inner side of the card feeding device in the same group of card picking and transporting systems and the two are directly adjacent inside and outside. In the same group of card picking and transporting systems: the card raising assembly 6 is arranged on the inner side of the card feeding device 3, the card raising assembly 6 and the card feeding device 3 are arranged outside the arc-shaped bend of the card storage slot 502, and the card loading drive mechanism of the card loading push head 505 is arranged Inside the arc-shaped curve of the card storage slot 502, the card inlet of the card feeding device 3 is close to the edge of the shuffling plate 2, and the card outlet of the card feeding device 3 is provided with a card receiving platform of the card pushing device 4, and one side of the card receiving platform is the card inlet of the card storage slot 502 in the card loading component, and the card outlet of the card storage slot 502 is connected to the card inlet of the card raising slot in the card raising component, wherein, the card outlet direction of the card feeding device 3 and the card inlet direction of the card raising component 6 are at an angle of 135° to 180°, and the card outlet of the card feeding device 3 is provided with a card pushing device, and the card pushing direction of the card pushing device 4 is at an angle of 80° to 100° with the card outlet direction of the card feeding device 3, and the card inlet direction of the card storage slot 502 in the card loading component 5 is at an angle of 0° to 10° with the card pushing direction of the card pushing device 4, and the card outlet direction of the card storage slot 502 in the card loading component 5 is at an angle of 0° to 5° with the card inlet direction of the card raising component 6.

[0113] When the mahjong machine is working, the shuffling plate rotates and the scraper does not move, and the mahjong tiles on the shuffling plate are respectively sent to the bottom of the card inlets of the four card feeding devices at the edge of the shuffling plate, and the mahjong tiles are sucked up by the card suction wheel in the card feeding device and straightened into the same direction and then sent into the card feeding channel and then sent out from the card outlet of the card feeding channel to the card receiving table in the card pushing device via the conveyor belt; then the card pushing head in the card pushing device pushes the stacked mahjong tiles into the card inlet of the storage slot; when the storage slot in the card loading assembly has stored enough mahjong tiles, wait for the card loading signal; when the mahjong machine receives the card loading signal, the card lifting support plate in the card lifting assembly descends, and the card loading push head 505 in the card loading assembly pushes the mahjong tiles in the storage slot to the card lifting support plate 601 in the card lifting assembly under the drive of the card loading drive mechanism for card loading, and after the card loading is completed, the card lifting support plate rises upward and is flush with the mahjong machine desktop.

[0114] One implementation method of the above-mentioned mahjong tile arrangement method is to use a one-time card arrangement:

[0115] That is, the card pushing device pushes all the mahjong tiles of one side (for example, 18 piles for each side) into the card storage slot of the card loading assembly at one time, and the card loading pushing head 505 is located outside the card inlet of the card storage slot; when the mahjong machine receives the card loading signal, the card lifting supporting plate in the card lifting assembly descends, and the card loading pushing head 505 in the card loading assembly, driven by the card loading driving mechanism, pushes the mahjong tiles in the card storage slot to the card lifting supporting plate 601 in the card lifting assembly for card loading. After the card loading is completed, the card lifting supporting plate rises upward and is flush with the tabletop of the mahjong machine.

[0116] Another implementation method of the above-mentioned mahjong tile arrangement method is to use a staged arrangement method:

[0117] Among them, an avoidance opening for a card-loading pusher to pass through is provided on the outer wall of the card-loading slot of the card-loading assembly. In this way, the card-loading pusher rotates in a single direction and circulates to push the mahjong tiles. After the card-pushing device pushes six and a half piles or thirteen mahjong tiles into the card storage slot of the ramp card-discharging device, the card-loading pusher enters and stays in the card storage slot, so that there are six and a half piles or thirteen mahjong tiles before the card-loading pusher, and the remaining mahjong tiles are pushed in by the card-pushing device after the card-loading pusher, so that the card-loading pusher is sandwiched between the front and rear rows of mahjong tiles; when the mahjong machine receives the first card-loading signal, the card-loading device's card-loading support plate descends, and the card-loading pusher first pushes the six and a half piles or thirteen mahjong tiles in front of it onto the card-loading support plate, and the card-loading support plate rises The mahjong tiles are put on the table, and the pusher for putting the tiles moves to the outside of the entrance of the storage slot through the opening on the side wall of the lifting slot; after the player takes away the six and a half or thirteen mahjong tiles on each side of the table, the mahjong machine receives the second signal for putting tiles, and the lifting plate goes down again, and the pusher for putting the tiles enters the storage slot again to push the remaining mahjong tiles on the lifting plate, and the lifting plate rises to put the mahjong tiles on the table, and the pusher for putting the tiles on the table again moves to the outside of the entrance of the storage slot through the avoidance opening on the side wall of the lifting slot, waiting for the next time to put tiles. In this way, by putting tiles in stages, the player can start playing the six and a half or thirteen mahjong tiles that are put on for the first time and stand them upright, eliminating the process of manual separation and arrangement, making the operation simpler and more convenient for the players, and providing a better entertainment experience. Furthermore, by loading the tiles in stages, the card feeding device and the card pushing device can continue to feed the mahjong tiles into the tile storage slot for storage while six and a half or thirteen tiles are loaded for the first time. In this way, the tile storage slot does not need to store all the mahjong tiles required for one side (for example, 18 tiles for each side) at one time, but only needs to store the number of mahjong tiles loaded at one time. Therefore, the length of the tile storage slot can be greatly shortened, thereby making the layout of the mahjong machine host more flexible and compact, the size of the mahjong machine smaller, or larger mahjong tiles can be used on the same size machine.

[0118] The staged card loading method is not limited to the above-mentioned first loading of six and a half piles of mahjong tiles, but can also be first loading a row of thirteen mahjong tiles (that is, thirteen mahjong tiles are arranged in a row, rather than stacking two mahjong tiles into a pile). When a row of thirteen mahjong tiles is used to load the cards first, the card pushing device only pushes a single mahjong tile into the card storage slot, rather than stacking two mahjong tiles into a pile and then pushing them into the card storage slot. There are many ways to realize pushing a single mahjong tile on the existing stacking push type card pushing device, for example: the card holding block of the card pushing device stops and only pushes the card into the card storage slot by the card pushing head; or, although the card holding block moves up and down, the card delivery device waits for the card pushing head to push the mahjong tile away before delivering the next mahjong tile after each mahjong tile is delivered to the card holding block; or, the first thirteen mahjong tiles are pushed into the card storage slot by the card loading push head, and the remaining mahjong tiles of each party are stacked into piles by the card pushing device and sent into the card storage slot. In this way, the structure is simple and the action is reasonable.

[0119] The card-loading bracket 501 is provided with a sensor for detecting the position state of the card-loading chain 503 or the card-loading pusher 505 and / or the mahjong tiles: in the card-loading assembly adopting the one-time card-loading method, at least two sensors are required, which are respectively used to detect the position information when the card-loading pusher stays outside the card inlet of the card storage slot waiting for pushing cards and the position information when the card-loading pusher stays at the card outlet of the card storage slot waiting for the lifting plate to lift the mahjong tiles onto the table; in the card-loading assembly adopting the staged card-loading method, at least three sensors are required, which are respectively used to detect the position information when the card-loading pusher stays outside the card inlet of the card storage slot waiting for pushing cards, the position information when the card-loading pusher stays in the card storage slot waiting for the first card-loading signal and the position information when the card-loading pusher stays at the card outlet of the card storage slot waiting for the lifting plate to lift the mahjong tiles onto the table. In this way, the accurate position of the card-loading pusher is determined by the sensor, timely feedback, convenient control, accurate action, and reduced failure.

[0120] Preferably, a sensor for detecting mahjong cards or a card pusher can be set at the card inlet and / or card outlet of the card storage slot. The above-mentioned sensor for detecting the card pusher can be a direct detection method or an indirect detection method, for example, by detecting the position of the driving mechanism of the card pusher to obtain the corresponding position information of the card pusher, such as detecting the position information of the card chain to obtain the position information of the card pusher, and another example is using a stepper motor or a motor with a built-in position sensor, and recording the rotation stroke information of the motor to convert the position information of the card pusher. The above-mentioned sensor can be various proximity sensors such as Hall sensors, photoelectric sensors, ultrasonic sensors, etc., or various contact sensors such as limit switches. Multiple or all of the above-mentioned sensors are arranged on a sensor circuit board 504 to facilitate wiring.

[0121] The first card-loading signal is generally generated by the player pressing a control button. The second card-loading signal can be generated by the player pressing a control button, or by a sensor that can detect whether the player has taken away the mahjong tiles on the lifting tray. For example, the sensor can be a photocell or a gravity sensor disposed on the lifting tray 601, or other sensors disposed on the desktop or the lifting bracket for detecting the action state and / or load-bearing state of the lifting tray.

[0122] The card pushing device for pushing the mahjong tiles stacked into a pile on the card conveyor belt into the card storage slot can be the above-mentioned movable side block, that is, a relatively independent pushing head for pushing the mahjong tiles out of the card conveyor belt, or it can be a card loading pushing head 505 in the card loading assembly. In this way, the card loading pushing head 505 is parked on the opposite side of the mahjong tile pushing outlet of the card conveyor belt. The card loading pushing head 505 has two action functions: one is that when the card storage slot stores mahjong tiles, the card loading pushing head pushes the mahjong tiles stacked into a pile on the card conveyor belt into the card inlet of the card storage slot, and then returns to its position to continue pushing the next pile of mahjong tiles until the card storage slot is full of mahjong tiles; the second is that after the card storage slot is full of mahjong tiles and a card loading signal is received, the card loading pushing head sends multiple piles of mahjong tiles in the card storage slot onto the mahjong machine table along the inclined card lifting support plate. This eliminates the need for a card transfer device to rotate and translate a pile of mahjong tiles and send them into the card storage slot in the prior art, eliminates the card transfer component and its driving motor, and also eliminates the original stacking and pushing device and its driving motor, greatly reducing the manufacturing cost, making the structure simpler, more convenient to assemble, greatly improving the reliability of the mechanism, and greatly reducing the maintenance cost. In addition, the card pusher 505 has a blocking portion that blocks the card delivery channel from continuing to discharge cards when the mahjong tiles are pushed out of the card receiving and conveying section.

[0123] One implementation method of the mahjong tile arrangement method of the mahjong machine using the tile conveyor belt is to use a one-time loading method, which is as follows:

[0124] A central control panel assembly 1, a shuffling plate 2 and a card scraper are arranged in the center of the frame bottom plate, and four groups of card picking and transporting systems are arranged around the shuffling plate. The card picking and transporting system includes a card feeding device 3 for picking up mahjong tiles from the shuffling plate one by one and sending them out, a card stacking device for stacking mahjong tiles into a pile, a card pushing device for pushing the mahjong tiles stacked into a pile into a card storage slot, and a ramp card discharging device for sending multiple piles of mahjong tiles in the card storage slot onto the mahjong machine table along the slope, and the ramp card discharging device includes a card loading assembly 5 and a card lifting assembly 6; the card lifting assembly is arranged on the inner side of the card feeding device in the same group of card picking and transporting systems and the two are directly adjacent inside and outside. In the same group of card picking and transporting systems: the card lifting assembly 6 is arranged on the inner side of the card feeding device 3, the card lifting assembly 6 and the card feeding device 3 are arranged outside the arc-shaped bend of the card storage slot 502, and the card loading pushing head 505 The card loading drive mechanism is arranged in the arc-shaped bend of the card storage slot 502, the card inlet of the card feeding device 3 is close to the edge of the shuffling plate 2, and the card outlet of the card feeding device 3 is arranged for stacking two mahjong tiles into a pile of cards. One side of the card outlet is the card inlet of the card storage slot 502 in the card loading assembly, and the card outlet of the card storage slot 502 is connected to the card inlet of the card raising slot in the card raising assembly, wherein the card outlet direction of the card feeding device 3 and the card inlet direction of the card raising assembly 6 are at an angle of 135° to 180°, and the card outlet of the card feeding device 3 is provided with a card pushing device, which is the card pushing head 505 in the card loading assembly, the card inlet direction of the card storage slot 502 in the card loading assembly 5 and the card outlet direction of the card feeding device 3 are at an angle of 85° to 115°, and the card outlet direction of the card storage slot 502 in the card loading assembly 5 and the card inlet direction of the card raising assembly 6 are at an angle of 0° to 5°.

[0125] When the mahjong machine is working, the shuffling plate rotates and the card scraper does not move. The mahjong tiles on the shuffling plate are respectively sent to the bottom of the card inlets of the four card feeding devices at the edge of the shuffling plate. One mahjong tile is sucked up by the card suction wheel in the card feeding device and straightened in the same direction. It is then sent into the card feeding channel and then sent out from the card outlet of the card feeding channel to the card receiving conveyor belt of the stacking device through the card feeding conveyor belt and is blocked by the card blocking member. Another mahjong tile is sucked up by the card suction wheel in the card feeding device and straightened in the same direction. It is then sent into the card feeding channel and then sent out from the card outlet of the card feeding channel through the card feeding conveyor belt to the previous mahjong tile. The mahjong tiles are stacked on the top of the board into a pile of mahjong tiles; then the loading pusher 505 pushes the stacked mahjong tiles into the card inlet of the card storage slot, and the loading pusher 505 returns to its position; when the card storage slot in the loading assembly has stored enough mahjong tiles, it waits for the loading signal; when the mahjong machine receives the loading signal, the lifting plate in the lifting assembly descends, and the loading pusher 505 in the loading assembly pushes the mahjong tiles in the card storage slot to the lifting plate 601 in the lifting assembly under the drive of the loading drive mechanism for loading. After the loading is completed, the lifting plate rises upward and is flush with the mahjong machine desktop.

[0126] Another implementation method of the mahjong tile arrangement method of the mahjong machine of this embodiment is to use staged card loading, which is as follows:

[0127] A central control disk assembly 1, a shuffling plate 2 and a card scraper are arranged in the center of the frame bottom plate, and four groups of card picking and transporting systems are arranged around the shuffling plate. The card picking and transporting system includes a card feeding device 3 for picking up mahjong tiles from the shuffling plate one by one and sending them out, a card stacking device for stacking mahjong tiles into a pile, a card pushing device for pushing the mahjong tiles stacked into a pile into a card storage slot, and a ramp card discharging device for sending multiple piles of mahjong tiles in the card storage slot onto the mahjong machine table along the slope, and the ramp card discharging device includes a card loading assembly 5 and a card lifting assembly 6; the card lifting assembly is arranged on the inner side of the card feeding device in the same group of card picking and transporting systems and the two are directly adjacent inside and outside, in the same group of card picking and transporting systems: the card lifting assembly 6 is arranged on the inner side of the card feeding device 3, the card lifting assembly 6 and the card feeding device 3 are arranged outside the arc-shaped bend of the card storage slot 502, and the card loading pushing head 505 is The card loading drive mechanism is arranged in the arc-shaped bend of the card storage slot 502, the card inlet of the card feeding device 3 is close to the edge of the shuffling plate 2, and the card outlet of the card feeding device 3 is arranged for stacking two mahjong tiles into a pile of card-bearing conveyor belts, one side of the card-bearing conveyor belt is the card inlet of the card storage slot 502 in the card loading component, and the card outlet of the card storage slot 502 is connected to the card inlet of the card raising slot in the card raising component, wherein the card outlet direction of the card feeding device 3 and the card inlet direction of the card raising component 6 are at an angle of 135° to 180°, and the card outlet of the card feeding device 3 is provided with a card pushing device, which is a pushing head for pushing the mahjong cards out of the card bearing conveyor belt, the card inlet direction of the card storage slot 502 in the card loading component 5 and the card outlet direction of the card feeding device 3 are at an angle of 85° to 115°, and the card outlet direction of the card storage slot 502 in the card loading component 5 and the card inlet direction of the card raising component 6 are at an angle of 0° to 5°. An opening for a card-raising pusher to pass through is provided on the outer side wall of the card-raising groove of the card-raising assembly. The card-raising pusher rotates cyclically in one direction to push the mahjong tiles.

[0128] When the mahjong machine is working, the mahjong tiles on the shuffling plate are respectively sent to the bottom of the card inlets of the four card feeding devices at the edge of the shuffling plate. The mahjong tiles are sucked up by the card suction wheels in the card feeding devices and straightened in the same direction. Then, they are sent into the card feeding channel and then sent out from the card outlet of the card feeding channel to the card receiving conveyor belt of the stacking device via the card feeding conveyor belt and are blocked by the card blocking member. The card pushing device pushes the mahjong tiles out of the card receiving conveyor belt and sends them into the card storage slot; after the card pushing device pushes six and a half or thirteen mahjong tiles into the card storage slot of the ramp card discharging device, the card loading pusher enters and stays in the card storage slot. In this way, there are six and a half or thirteen mahjong tiles before the card loading pusher, and the remaining mahjong tiles are pushed in by the card pushing device after the card loading pusher, so that the card loading pusher is clamped between the front and rear two mahjong tiles. The card raising device is used to raise the mahjong tiles and place them between the mahjong tiles; when the mahjong machine receives the first card-loading signal, the card-raising plate of the card-raising device descends, and the card-loading pusher first pushes the six and a half or thirteen mahjong tiles in front of it onto the card-raising plate, and the card-raising plate rises to place these mahjong tiles on the table, and the card-loading pusher moves to the outside of the entrance of the card storage slot through the opening on the side wall of the card-raising slot; after the player takes away the six and a half or thirteen mahjong tiles of each side on the table, the mahjong machine receives the second card-loading signal, and the card-raising plate descends again, and the card-loading pusher enters the card storage slot again to push the remaining mahjong tiles onto the card-raising plate, and the card-raising plate rises to place the mahjong tiles on the table, and the card-loading pusher moves to the outside of the entrance of the card storage slot through the avoidance opening on the side wall of the card-raising slot again, waiting for the next card-loading.
