The four card outlets are arranged in a windmill shape, and each card outlet is inclined at an angle with the bottom edge of the table, namely the windmill shape is inclined, so that the table top can be made smaller, and the inclination of the card strips also accords with the habit of a player; secondly, when the card is played, the whole card pier is not built and then lifted up to the tabletop, but pushed up to the tabletop along the slope, so that the space inside the machine can be reduced, and the size of the whole machine can be reduced. However, in the card discharging device, the whole card storage groove is arranged in a slope shape, the resistance of the card feeding process is large, the load of a steel wire rope motor is large, steel wires are easy to shake and break, the card feeding process is not stable enough, the service life of the steel wire rope is low, the arrangement of the card storage groove, the stacking and pushing machine head and the conveying device (a mechanism for picking up mahjong cards from a large tray and conveying the mahjong cards to the stacking and pushing machine head) is unreasonable, the conventional square independent stacking and pushing machine head is difficult to push mahjong cards to a card inlet of a card storage groove track, and the height of a host machine is high.

The patent document with the publication number of CN201783185U discloses a chain-driven slope tile discharging device for a full-automatic mahjong machine, which is provided with four lifting tile lifting plates hinged with a tabletop, one end of each lifting tile lifting plate is a tile inlet, the outer side of each lifting tile plate is provided with a conveying belt, one side of the conveying belt is provided with a stacking mechanism, the outer sides of the four conveying belts are provided with arc-shaped tile storage grooves, an annular closed chain is arranged below each groove, and vertical chain rods are arranged on each chain at intervals of a set distance. The mahjong tile discharging device adopts the chain to push the mahjong tile, and overcomes the problem of low service life of a steel wire rope, but the working noise of the machine is large, the plane size of a host machine is enlarged, and other defects are not improved.

Patent document with publication number CN102133480A discloses a full-automatic mahjong machine, which comprises a mahjong feeding system, a mahjong lifting system and a mahjong shuffling large tray, wherein the mahjong feeding system comprises four mahjong pushing devices, four mahjong feeding tracks and a chain transmission device. The height of the tile feeding system is basically level with that of the tile lifting system, so that although the height of the host is reduced, the arrangement position of the tile lifting system can cause interference to the large-disc shuffling and the tile feeding system for sucking the mahjong tiles, and the tile lifting system is only suitable for small mahjong tiles. In addition, the arrangement of the tile outlet of the tile feeding system and the tile inlet of the tile feeding track is unreasonable, the tile pushing device does not have the tile stacking function, and the mahjong tiles are automatically stacked on the tile bearing table board, so that the mahjong tiles are not stacked neatly and are easy to move and misplaced, and the mahjong tiles cannot enter the tile feeding track, and generate faults such as confusion in the tile feeding track. In addition, after the horizontal card feeding rail is adopted, mahjong tiles close to the card outlet of the card feeding rail are very easy to fall from the card outlet back to the shuffling large tray; the adoption of the chain and the flag wheel structure has high noise.

The automatic mahjong machine disclosed in patent documents with publication numbers of CN201906453U and CN201949619U, wherein a mahjong storage plate in a mahjong storage track of the mahjong machine is obliquely arranged, one end of the mahjong storage plate is in butt joint with a mahjong bearing plate, a mahjong stacking pushing head pushes mahjong on the mahjong bearing plate onto the mahjong storage plate, and after mahjong pieces on the mahjong storage plate are arranged in a row, a mahjong feeding pushing head pushes the whole row of mahjong pieces to an upper mahjong piece assembly; because the pile card is pushed away and is provided with the groove of dodging, upward be provided with the push rod on the card is pushed away and is pushed away the head to make two push away and to push away and set up alternately from top to bottom, both can avoid each other through dodging the groove when pushing away the tablet respectively like this. However, since the card storage rail is passed over the conveying section of the card feeding device, the height of the main body of the mahjong machine is high (the height of the card feeding device and the height of the card feeding device are overlapped), and in addition, the L-shaped card storage rail is short, so that the universality is poor.

The automatic mahjong machine disclosed in patent documents with publication numbers CN103861280a and CN104645608A also has the problems of higher height of the main machine (height superposition of the card feeding device and the card feeding device), shorter L-shaped card storage track, and the like. In addition, after the horizontal card feeding rail is adopted, mahjong tiles close to the card outlet of the card feeding rail are very easy to fall from the card outlet back to the shuffling large tray; the steel wire rope is adopted to drive the card feeding pushing head to move, and the steel wire rope and the side wall of the track are severely rubbed, so that the service life is low.

The patent document with the publication number of CN204699375U discloses an automatic mahjong machine with an improved structure, which comprises a mahjong feeding system, a mahjong lifting system and a mahjong shuffling large tray, wherein the mahjong feeding system comprises four mahjong feeding mechanisms, each mahjong feeding mechanism comprises a transmission frame and a conveying belt fixed on the transmission frame, the four mahjong feeding mechanisms are sequentially connected to form a rectangular structure, and the mahjong shuffling large tray is arranged in the four mahjong feeding mechanisms. The mahjong tile feeding track adopts the whole large arc-shaped structure, so that the friction force between mahjong tiles and the mahjong tile feeding track is reduced, and the faster mahjong tile feeding speed and smaller mahjong tile feeding noise are ensured. And, the arrangement positions of the card feeding system and the card sending system are designed in an overlapping mode, so that the height of the host is reduced. However, because the mahjong tile feeding device adopts straight lines to feed and discharge mahjong tiles, the tile outlet of the mahjong tile feeding device and the tile inlet of the tile feeding track still cannot be reasonably arranged, the tile pushing resistance of the stacking pushing device is large and the tiles are easy to clamp, and the large arc-shaped tile feeding track causes the increase of the table surface size of the mahjong machine. The patent document with the publication number of CN105363195A discloses a mahjong machine tile feeding device, wherein the tile feeding channel is curved by reasonably adjusting the positions of the tile outlet and the tile inlet of the tile feeding device, so that mahjong tiles fed out by the tile feeding device onto the tile supporting block of the tile pushing device and mahjong tiles pushed out by the tile pushing device are tidy and have smaller resistance.

Patent document with publication number CN105413161a discloses a tile feeding driving mechanism, a tile feeding assembly and a mahjong machine, the tile feeding driving mechanism of the mahjong machine comprises a tile feeding bracket, a tile storage groove, a tile feeding guide rail, a tile feeding pushing head and a steel wire rope, rolling elements are arranged at positions, close to the tile feeding guide rail and/or the tile storage groove, of the steel wire rope, the rolling elements are rotatably arranged on the tile feeding guide rail or the tile feeding bracket, and the part of the steel wire rope in the tile storage groove is in rolling contact with a plurality of rolling elements and keeps a gap with the side wall of the tile feeding guide rail and/or the tile storage groove. According to the scheme, rolling friction of the steel wire rope is used for replacing sliding friction of the steel wire rope in the prior art, so that friction resistance of operation of the steel wire rope is greatly reduced, and the influence on the service life and operation stability of the steel wire rope due to sliding friction contact between the part of the steel wire rope in the card storage groove and the arc-shaped curved side wall of the card loading guide rail and/or the card storage groove is avoided.

The mahjong machine comprises a mahjong feeding support, a mahjong feeding pushing head, a mahjong feeding driving mechanism and a mahjong feeding driving mechanism, wherein the mahjong feeding support is provided with a mahjong storage groove, a first mahjong feeding pushing head and a second mahjong feeding pushing head, a gap is formed in the inner side wall of the middle position of the mahjong storage groove, the mahjong storage groove is communicated with a reversing groove through the gap, the first mahjong feeding pushing head is driven by the mahjong feeding driving mechanism to move from the outside of a mahjong feeding inlet of the mahjong storage groove to the vicinity of the gap and then returns, the second mahjong feeding pushing head is driven by the mahjong feeding driving mechanism to move from a mahjong outlet of the mahjong storage groove to the reversing groove and then returns, the mahjong feeding driving mechanism comprises a first mahjong feeding pushing rod and a second mahjong feeding pushing rod which are in reciprocating motion and are matched with each other, and the first mahjong feeding pushing head is arranged on the first mahjong feeding pushing rod, and the second mahjong feeding pushing head is arranged on the second mahjong feeding rod. The scheme adopts the mode of pushing the cards by the power of the two card pushing rods, and completely avoids the defects of large resistance between the card pushing head and the guide rail, large working noise of the chain and the like in the prior art.

However, although the above-mentioned slope mahjong machine in the prior art is repeatedly developed and improved by the inventor, the following technical problems have not been completely overcome yet:

1. in the prior art, the card feeding device and the card lifting assembly are arranged on the inner side of the card storage groove, and the card lifting assembly in one group of card picking and conveying systems is arranged on the inner side of the card feeding device in the other group of card picking and conveying systems, so that adjacent card picking and conveying systems are arranged in a staggered manner to prolong the length of the card storage groove, but the quantity of mahjong tiles which can be stored is still limited, and the mahjong tiles are particularly large in size.

2. Because the adjacent card picking and carrying systems are arranged in a staggered way, the upper and lower overlapping between the adjacent card sending device and the card lifting assembly is unavoidable, so that the overall height of the mahjong machine is increased.

3. Because the adjacent card picking and carrying systems are arranged in a staggered manner, the card picking and carrying systems are limited by the fact that the card lifting assembly and the card storage groove cannot be overlapped up and down and the length of the card storage groove, the card lifting opening arrangement positions of the adjacent card picking and carrying systems are greatly limited, and the using comfort of the mahjong machine is affected. Taking a mahjong machine with a square of 85cm as an example, as shown in fig. 1, four rows of mahjong walls of a table top 11 are directly lifted from square mahjong lifting openings 111 to form a windmill shape, and the distance between two opposite rows of mahjong walls is 35cm, so that the area where a player is used to place a bar tile on the left hand side is very small (namely, the distance between the mahjong walls and the edge of a table top frame is too small), and the tile cannot be placed, and the player is required to move the mahjong walls to leave the bar tile area, thereby influencing the use comfort.

4. Because the adjacent card picking and carrying systems are arranged in a staggered manner, the arc-shaped bending of the card storage groove is small (namely, the card inlet direction and the card outlet direction of the card storage groove are arranged at an acute angle), and the shape is irregular, so that the card feeding driving mechanism for driving the card feeding pushing head in the card storage groove to move has a complex structure, high manufacturing precision requirement, high reliability, high manufacturing cost and high use and maintenance cost.

Patent document with publication number CN106166379a discloses a ring-shaped tile pushing device of an automatic mahjong machine and a mahjong machine. The mahjong tile pushing device comprises a motor, a rotary table, a tile pushing block assembly, an annular vertical rail, a base and an annular tile blocking side plate of the base, wherein the annular vertical rail is arranged on the surface of the base, the annular vertical rail and the annular tile blocking side plate of the base form a mahjong tile pushing groove, the mahjong tile pushing groove is provided with a mahjong tile inlet and a mahjong tile outlet, the annular vertical rail is provided with the tile pushing block assembly, the inner side of the tile pushing block assembly is provided with a clamping groove, the tile pushing block assembly is movably inserted on the annular vertical rail through the clamping groove, the part of the tile pushing block assembly which is arranged in the mahjong tile pushing groove is provided with a tile pushing arm for pushing tile transmission, the motor is arranged on the base, the motor is connected with the rotary table for transmission, and the rotary table is provided with a driving part for driving the tile pushing block assembly to push tiles in the mahjong tile groove. In the structure, the card pushing block is inserted on the annular vertical track and slides to push cards, the annular vertical track is composed of an arc section and a straight line section, and the card pushing block is driven by the turntable to reciprocate in the card pushing groove. Therefore, the friction resistance between the card pushing block and the track is large, the service life of the component is low, the movement path of the card pushing block is irregular, the structure of the turntable driving card pushing block 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. Moreover, because the tile pushing device is required to be matched with the linear tile bearing table of the tile stacking device and the linear tile lifting groove of the tile lifting device, and the tile pushing block assembly moving along the annular vertical track has a large volume, the annular vertical track is required to be composed of an arc section and a linear section, otherwise, the mahjong tiles can be blocked or even dead due to moving. Therefore, the tile pushing block in the structure must return along the original path when pushing the mahjong tile out of the mahjong tile slot of the tile pushing device.

Patent documents such as CN105903186A, CN205699378U, CN205699375U, CN205832557U discloses a tile feeding device of an automatic mahjong machine, which comprises a conveying belt and a driving wheel for driving the conveying belt to run, wherein the conveying belt comprises a conveying section and a tile bearing section, the tile bearing section is lower than the conveying section, the height difference of the conveying section and the tile bearing section is larger than the thickness of mahjong tiles, the mahjong tiles are conveyed to the tile bearing section through the conveying section and stacked, and the tile feeding device further comprises a tile blocking plate for blocking the mahjong tiles from falling out of the tile bearing section. The mahjong pieces are stacked by the mahjong piece bearing section of the mahjong piece conveying device, and the mahjong pieces are pushed into the mahjong piece storage groove by the mahjong piece rotating piece through the mahjong piece rotating groove. In the card conveying device, the card bearing section and the conveying section of the card conveying device adopt the same power, and the load of the conveying motor is large; the card transferring devices such as the card transferring piece, the card transferring groove and the like are required to be matched to realize the connection of the card feeding device and the card storing groove, and the card transferring device has high manufacturing precision requirement and difficult assembly and matching. Because the contact position of the first mahjong tile stacked with the tile carrying section conveyer belt is greatly uncertain in the falling process, the position of the first mahjong tile (the mahjong tile below) is easily deviated, namely, the situation that the two mahjong tiles stacked are not flush up and down and even are blocked by pushing, and the like is easy to occur, and because the mahjong tiles are pushed along the conveying direction of the vertical conveyer belt to cause the conveyer belt to deviate, the acting force of the mahjong tiles on the conveyer belt along the conveying direction of the vertical conveyer belt is required to be reduced as much as possible when the mahjong tiles are sent out from the tile carrying section, therefore, the tile picking and conveying device in the patent literature is required to adopt a tile turning device to be matched with the tile carrying section of the tile conveying device, and the flush and small-radius rotary translation of the two mahjong tiles is realized through a tile turning piece.

Example 1:

the automatic mahjong machine as shown in fig. 4 comprises a central control board assembly, a shuffling tray 2 and a scrapper 201, wherein the central control board assembly is positioned in the center of a bottom plate of a machine frame, four groups of picking and carrying systems are arranged around the shuffling tray, each picking and carrying system comprises a mahjong feeding device 3 for picking mahjong pieces one by one and sending out from the shuffling tray, a pushing device 4 for stacking and pushing out two mahjong pieces into one pier, and a slope discharging device for feeding the arranged mahjong pieces along a slope to a tabletop of the mahjong machine, and each slope discharging device comprises a mahjong feeding assembly 5 and a mahjong lifting assembly 6.

The card feeding device 3 comprises a card feeding box, a card feeding channel for feeding mahjong cards is arranged in the card feeding box, a card sucking wheel is arranged at a card feeding port of the card feeding channel, and a conveying belt driven by a card feeding motor is arranged in the card feeding channel.

In this embodiment, the card feeding channel may be a conventional linear channel, but an arc card feeding channel may also be selected for optimizing the structural layout. In order to ensure the delivery reliability of the mahjong pieces, the height of the card outlet of the card delivery channel is not lower than the height of the card inlet of the card delivery channel. The specific structure of the card feeding device can be seen in patent document CN105413161 a.

For example, in order to solve the technical problem in the prior art, that is, "the arrangement of the card outlet of the card feeding device and the card inlet of the card storage slot in the card feeding assembly is unreasonable, so that the mahjong tiles pushed by the card pushing device are easy to be scattered and blocked", the inner and outer side walls of the card feeding channel are arc-shaped, so that the card feeding channel is arc-shaped, and an included angle is formed between the card inlet and the card outlet of the card feeding channel, and the included angle ranges from 1 degree to 15 degrees. The tile inlet and the tile outlet of the tile feeding device are not arranged on the same straight line, but are staggered by a certain angle, so that the tile outlet of the tile feeding device can be arranged at an included angle of 80-100 degrees with the tile pushing direction of the tile pushing device, and mahjong tiles stacked on a tile bearing table of the tile pushing device and mahjong tiles pushed by the tile pushing device are tidy and have smaller resistance. In addition, the card inlet of the card sending channel can be arranged at the edge of the shuffling large tray which does not need to be reduced in size, so that the influence of the reduction of the shuffling large tray on shuffling is avoided, and the shuffling quantity and the size of mahjong tiles used are limited. The included angle range is 1-15 degrees, so that the purpose can be achieved, the mahjong tile conveying channel cannot be influenced by the fact that one conveying belt conveys mahjong tiles due to overlarge radian, and the included angle range can be further enlarged by arranging a plurality of conveying belts under the condition of not counting cost.

The card pushing device in this embodiment can realize a stacking pushing function, and includes a card pushing head 401 and a card bearing table 402. The specific structure of the card pushing device can be referred to patent documents with publication numbers of CN201906453U, CN201949619U, CN103861280A and CN 204699375U. In general, a tile pushing device with stacking and pushing functions comprises a machine head box, a tile pushing motor is arranged on the machine head box, a transmission mechanism is arranged in the machine head box, a tile pushing head and a tile bearing table are arranged outside the machine head box, the tile pushing motor drives the tile bearing table to move up and down through the transmission mechanism so as to realize stacking of mahjong tiles, and the tile pushing motor drives the tile pushing head to horizontally move through the transmission mechanism so as to push out the stacked mahjong tiles. Of course, the tile pushing device can also be other mechanisms which can realize that a tile pier of mahjong tiles is carried on the tile carrying table and the tile pushing head pushes out the tile pier of mahjong tiles. The machine head box is provided with a counting detection device for detecting the number of pushing cards and/or detecting the number of pushing cards, a card blocking frame is arranged near the card bearing table 402, a card outlet of the card feeding device and the card blocking frame are respectively positioned at two opposite sides of the card bearing table 402, one side of the card bearing table 402 is provided with a card pushing head, and the other side of the card bearing table is an outlet for pushing the mahjong cards out of the card bearing table by the card pushing head. The card feeding detection device for detecting whether the mahjong pieces are fed to the mahjong carrying table at the mahjong outlet of the card feeding device can be arranged on the mahjong blocking frame, but is preferably arranged on one side of the mahjong carrying table 402 where the mahjong pushing head is arranged, so that the detection precision and reliability are improved, and the card feeding detection device can be arranged on the extension part of the mahjong blocking frame or on the mahjong pushing head.

The tile feeding assembly is shown in fig. 4 and 5, and comprises a tile feeding support 501, wherein a tile storage groove 502 for storing a plurality of piers of mahjong tiles and a tile feeding push head 505 for pushing the mahjong tiles out of the tile storage groove 502 are arranged on the tile feeding support 501, the tile storage groove 502 is curved in an arc shape, the bending angle is larger than 180 degrees, the tile feeding direction of a tile feeding opening on the tile storage groove 502 forms an included angle of 45-90 degrees with the tile discharging direction of a tile discharging opening, and the tile feeding push head 505 is driven by a tile feeding driving mechanism to move from the outside of the tile feeding opening of the tile storage groove 502 to the outside of the tile discharging opening of the tile storage groove 502 along the tile storage groove 502.

The specific structure of the card lifting assembly can be seen in patent documents with publication numbers CN201906453U, CN201949619U, CN102133480A, CN103861280A, CN105413161a and CN204699375U, in general, one card lifting assembly 6 includes a card lifting support, a card lifting support plate 601 and a card lifting motor, the card lifting support plate is provided with a card lifting groove, the card lifting support plate is located at the upper part of the card lifting groove, one end (i.e. a card outlet end) of the card lifting support plate is installed on the card lifting groove, the other end of the card lifting support plate (i.e. a card inlet end) can move and is driven by the card lifting motor to lift up and down through a cam, a card lifting rocker or other transmission mechanism, and a sensor for detecting the position of the card lifting support plate, for example, an upper hall element, a lower hall element or a light eye, is further arranged on the card lifting support plate.

In the mahjong machine, four groups of mahjong picking and carrying systems are respectively and independently arranged without mutual staggered arrangement, namely, the mahjong lifting components are arranged at the inner sides of the mahjong sending devices in the same group of mahjong picking and carrying systems and are directly adjacent to each other inside and outside, and in the same group of mahjong picking and carrying 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 bending of the card storage groove 502, the card lifting driving mechanism of the card lifting push head 505 is arranged inside the arc-shaped bending of the card storage groove 502, the card discharging direction of the card feeding device 3 and the card feeding direction of the card lifting assembly 6 form an included angle of 135-180 degrees, the card discharging port of the card feeding device 3 is provided with a card pushing device, the card pushing direction of the card pushing device 4 and the card discharging direction of the card feeding device 3 form an included angle of 80-100 degrees, the card feeding direction of the card storage groove 502 in the card lifting assembly 5 and the card pushing direction of the card feeding device 4 form an included angle of 0-10 degrees, and the card discharging direction of the card storage groove 502 in the card lifting assembly 5 and the card feeding direction of the card feeding assembly 6 form an included angle of 0-5 degrees.

Like this, four sets of card handling systems of picking up set up independently respectively, do not have the crisscross setting each other, have following advantage:

4. The adjacent card picking and carrying systems are independent, and are not staggered, so that the card lifting opening of the table top of the mahjong machine is not limited by the position and the length of the card storage groove, the card lifting opening can move inwards, the setting space of the card feeding assembly is larger, the arc radius of the card storage groove can be larger, and the longer card storage quantity of the card storage groove is more. By taking a mahjong machine with a square of 85cm and adopting the structure of the invention as an example, as shown in fig. 2 and 4, four rows of mahjong walls of a table top 11 are directly lifted from square mahjong lifting openings 111 to form a windmill shape, the distance between two opposite rows of mahjong walls (namely two opposite mahjong lifting openings) is 30.5cm, and the distance can be reduced to 30.5+/-1 cm according to the different sizes of the mahjong, so that the area for placing the mahjong on the left hand habit of a player is larger, the mahjong is easier to place, and the player does not need to deliberately move the mahjong walls to vacate the mahjong area, thereby having better use experience and comfort.

In addition, the four sets of card picking and carrying systems are respectively and independently arranged, and a larger space can be reserved between two adjacent card loading assemblies, as shown in fig. 51 and 52, so that the control main board 7, the transformer 8, the large disc motor 202 and the like which are originally placed in the electric box below the bottom plate of the mahjong machine can be placed at the gap between the two card loading assemblies at the periphery of the large shuffling disc 2, the electric box can be made smaller and thinner, the electric box can be removed in the central control structure scheme using the side-hung door structure, the height and the manufacturing cost of the main machine of the mahjong machine are greatly reduced, and the electric box in the mahjong machine with the four-foot structure can be made almost invisible. And the electric appliance box becomes smaller and thinner, so that the use experience and the comfort are better.

The card feeding driving mechanism can take various forms, such as a wire rope traction mechanism, a chain traction mechanism, a deflector rod transmission mechanism, a gear transmission mechanism, a cam transmission mechanism and the like, and in this embodiment, as shown in fig. 4, 10 and 11, the card feeding driving mechanism is a card feeding push rod 503 rotating around a fixed point, and a card feeding push head 505 is mounted on the card feeding push rod 503. One embodiment is that the card-feeding pushrod 503 is directly fixed to the output shaft of the card-feeding motor 506, as shown in fig. 10; another embodiment is that the card-feeding push rod 503 is in transmission connection with the card-feeding motor 506 through a gear transmission mechanism 507, as shown in fig. 11. The single push rod is adopted to push the cards, the rotation center of the card feeding push rod is concentric with the arc bending center of the card storage groove, so that the direction of the pushing force is basically in the arc tangential direction and is basically coincident with the movement direction, the pushing force is smaller (component force is reduced) under the same shape, the motor load is smaller, and the reliability is better.

In order to further prolong the length of the card storage groove and simultaneously reduce the card pushing resistance of the card feeding pushing head as much as possible, the card storage groove is provided with a first arc-shaped card storage part 5021 and a second arc-shaped card storage part 5022, the first arc-shaped card storage part 5021 is close to a card inlet of the card storage groove, the second arc-shaped card storage part 5022 is close to a card outlet of the card storage groove, the bending radius of the second arc-shaped card storage part 5022 is larger than that of the first arc-shaped card storage part 5021, and the bending angle of the second arc-shaped card storage part 5022 is not smaller than 180 degrees. In order to minimize the tile pushing resistance of the tile pushing head and ensure that the tile wall of the table top of the mahjong machine is tidy and not messy, the second circular arc tile storage part 5022 is directly communicated with the tile inlet of the tile lifting assembly, and the tile inlet direction of the tile lifting assembly is consistent with the tangential direction of the second circular arc tile storage part 5022. In order to ensure smooth and rapid tile pushing, reduce the load of the tile feeding motor, and facilitate the fixed connection of the tile feeding pushing head and the tile feeding pushing rod, it is preferable that the difference of the bending radius of the second circular arc tile storage part 5022 and the first circular arc tile storage part 5021 is smaller than the length of one mahjong tile.

In order to reduce the friction resistance between the mahjong pieces and the bottom of the mahjong storage groove and not to increase the cost greatly, the bottom of the mahjong storage groove is provided with a mahjong storage groove bottom patch, and the mahjong storage groove bottom patch is preferably made of a material with smooth and wear-resistant surface, such as polyoxymethylene, polytetrafluoroethylene and the like. The card storage groove bottom patch is used as an independent component to be arranged in the card storage groove of the card loading support, and the card loading support is made of materials with poor performance and low price, so that the card storage groove bottom patch can meet the use requirement, and the manufacturing cost of a machine can be reduced. The patch at the bottom of the card storage tank is preferably matched and positioned with the card feeding bracket through a plurality of buckles and locked and fixed through fasteners so as to be convenient to install. Similarly, in order to reduce frictional resistance between the mahjong pieces and the inner side wall and the outer side wall (particularly the side wall of the arc-shaped bending section) of the mahjong storage tank, and at the same time, the cost is not greatly increased, part or all of the inner side wall and/or the outer side wall of the mahjong storage tank is provided with side wall patches, and the side wall patches are preferably made of materials with smooth and wear-resistant surfaces, such as polyoxymethylene, polytetrafluoroethylene and the like. In this embodiment, the patches on the bottom, inner side wall and outer side wall of the card slot are integrally formed from a smooth wear-resistant material.

The mahjong tile storage groove can be made into a slope form with a gentle slope from the mahjong tile inlet to the mahjong tile outlet, but the tile pushing resistance of the mahjong tile pushing head is increased in this way. In addition, the card storage groove is provided with a slope, so that the card lifting assembly can further prolong the length of the card lifting supporting plate in the card lifting assembly and slow down the inclined slope of the card lifting supporting plate, and the card feeding resistance is reduced. The tile discharging slope can be formed at the bottom of the tile storing tank, but is preferably arranged on a tile storing tank bottom patch, namely, most of the tile storing tank bottom patch is horizontally arranged, and the tile discharging slope capable of lifting the mahjong tiles is formed at the tile discharging opening close to the tile storing tank bottom patch. The tile feeding slope surface which is convenient for the mahjong tile to enter is formed at the tile feeding opening of the tile storage tank bottom patch. In order to avoid the occurrence of the faults of arching, jumping and the like in the mahjong tiles in the tile storage groove during the tile pushing process of the tile pushing device, a tile pressing plate for limiting the tile storage height of the tile storage groove is arranged above the tile storage groove on the tile feeding support 501, and covers part or all of the top of the tile storage groove.

In order to avoid the upward and downward displacement of the mahjong tiles on the tabletop of the upward mahjong machine, the horizontally moving upward mahjong tile pushing head is provided with a plurality of tile pushing parts which are respectively contacted with two upper and lower superposed mahjong tiles in the same pier, wherein the tile pushing parts contacted with the lower mahjong tile are protruded out of the tile pushing parts contacted with the upper mahjong tile, so that when the upward mahjong tile pushing head pushes the multi-pier mahjong tile to horizontally move, the upper mahjong tile is behind the lower mahjong tile, and when the upward mahjong tile pushing head pushes the last pier mahjong tile to the upward inclined upward mahjong tile supporting plate, the upper mahjong tile is flush with the lower mahjong tile.

In order to avoid collision of the card feeding pushing head outside the card inlet of the card storage groove and the card pushing head 401 in the card pushing device and avoid blocking mahjong tiles sent by the card sending device, the card feeding pushing head 505 and the card pushing head 401 in the card pushing device adopt a dislocation avoiding design, and are arranged on one side of the card bearing platform 402 together with the card pushing head 401 before feeding the cards. In order to avoid the disorder and card easily caused by the mahjong tiles pushed by the tile pushing device, the tile inlet of the tile storage groove is arranged at an included angle of 80-100 degrees with the tile outlet of the tile feeding device, and the tile pushing direction of the tile pushing head 401 of the tile pushing device 4 is matched with the tile inlet of the tile storage groove.

The card blocking frame can be fixedly connected with the card feeding bracket or integrally formed. The card sending box, the card feeding bracket and the card lifting bracket in the square card picking and carrying system can be fixedly connected or a plurality of combined integrated forming manufacturing. In the embodiment, the card sending box and the card lifting bracket in the square card picking and carrying system are annular shells manufactured by integral forming, so that the card picking and carrying system is convenient to assemble and simple and reliable in structure.

In the card picking and carrying system, the matching relationship among the card storage groove in the card loading assembly, the card bearing table in the card pushing device and the conveying channel in the card conveying device is particularly important, and the stacking and pushing process of the card pushing device is determined.

In one embodiment of the invention, the card slot has a card inlet height that is lower than the card outlet height of the card delivery device and a difference M between the two heights that is greater than the height of one mahjong tile and less than the height of two mahjong tiles, preferably 21 to 33 cm. The card pushing process is as follows: the holding table 402 first holds a first mahjong tile 10 at an initial position slightly lower than the tile outlet of the tile feeding device; then the second mahjong tile is carried by descending one height, the height of the tile carrying platform is close to the height of the tile inlet of the tile storage groove, and the piled mahjong tile is pushed into the tile inlet of the tile storage groove 502 by the tile pushing head 401; finally, the deck 402 is raised to the initial position to await the next mahjong tile.

In another embodiment of the invention, the card slot has a card inlet height that is less than the card outlet height of the card delivery device and a height difference M between them that is less than the height of a mahjong tile, preferably 1 to 13 cm. The card pushing process is as follows: the holding table 402 first holds a first mahjong tile 10 at an initial position slightly lower than the tile outlet of the tile feeding device; then descending one height to receive the second mahjong tile; then the card bearing table 402 is lifted to an initial position, and the height of the card bearing table is close to the height of the card inlet of the card storage groove; the piled mahjong pieces are pushed into the mahjong inlet of the mahjong storage groove 502 by the mahjong pushing head 401, and after the mahjong pushing head 401 retreats, the next mahjong piece is waited.

The two embodiments can lead the actions of the card bearing table and the card pushing head in the card pushing device to be simple and reasonable and lead the reliability to be better.

In the present invention, the card-feeding push rod 503 may swing back and forth or may rotate in a single direction, as shown in fig. 12, so that an opening for passing the card-feeding push head and the card-feeding push rod is formed on the outer side wall of the card-feeding slot of the card-feeding assembly 6, and the opening is in an inverted L shape. That is, the tile feeding pushing head can circularly rotate in one direction, so that the slope tile-discharging mahjong machine can realize tile feeding in stages: in the existing slope tile-discharging mahjong machine, mahjong tiles are conveyed to a tile pushing device by a tile conveying device after being shuffled by a large tile tray, the tile pushing device pushes mahjong tiles stacked into a slope tile-discharging device (one tile is two tiles stacked up and down), the mahjong tiles are arranged into a row of a plurality of tiles in the slope tile-discharging device, and after the mahjong tiles are arranged to a specified tile number, the mahjong tiles are all pushed onto a corresponding table top by the slope tile-discharging device at one time. Thus, according to different playing habits, the existing mahjong machine arranges a row of mahjong tiles (for example, 18 tiles on four sides) on the square of the table top, and players grasp and arrange the mahjong tiles manually and erect the grasped mahjong tiles in turn according to the direction of the mahjong tiles (for example, 13 tiles on four sides, one more dealer). In the invention, because the card feeding push head can realize unidirectional circular rotation, the card feeding in stages can be realized, and the card feeding method comprises the following steps: after the six-pier half or thirteen mahjong tiles are pushed into the tile storage groove of the slope tile outlet device by the tile pushing device, the tile pushing head enters and stays in the tile storage groove, so that the six-pier half or thirteen mahjong tiles are arranged before the tile pushing head, and the rest mahjong tiles are pushed into by the tile pushing device after the tile pushing head is arranged, so that the tile pushing head is clamped between the front row of mahjong tiles and the rear row of mahjong tiles; when the mahjong machine receives a first tile feeding signal, the tile feeding supporting plate of the tile feeding device descends, the tile feeding pushing head firstly pushes six piers and half or thirteen mahjong tiles in front of the tile feeding device to the tile feeding supporting plate, the tile feeding supporting plate lifts the mahjong tiles to the tabletop, and the tile feeding pushing head moves to the outside of the inlet of the tile storage groove through the opening on the side wall of the tile feeding groove; after the player takes off the six piers or thirteen pieces of mahjong tiles on the four sides of the tabletop, the mahjong machine receives a second tile feeding signal, the tile lifting supporting plate descends again, the tile feeding push head enters the tile storage groove again to push the rest mahjong tiles to the tile lifting supporting plate, the tile lifting supporting plate is lifted to feed the mahjong tiles to the tabletop, and the tile feeding push head moves to the outside of the inlet of the tile storage groove again through the avoidance opening on the side wall of the tile lifting groove and waits for the next tile feeding. Therefore, by adopting staged tile feeding, players can start playing by erecting six piers and half or thirteen mahjong tiles on the first time, the manual tile distributing and arranging process is omitted, the operation of the players is simpler and more convenient, and the entertainment experience is better. In addition, by adopting staged tile feeding, the tile feeding device and the tile pushing device can continuously feed the mahjong tiles into the tile storage groove for storage when six tiles or thirteen tiles are fed for the first time, so that the tile storage groove is not required to store all mahjong tiles (such as 18 tiles on four sides) required by one side at a time, and only the number of the mahjong tiles fed once is required to be stored, thus the length of the tile storage groove can be greatly shortened, and the layout of a main machine of the mahjong machine is more flexible and compact, the volume of the mahjong machine is smaller, or larger mahjong tiles can be used on the same volume machine.

The mahjong tile arranging method of the mahjong machine comprises the following steps:

the center of the bottom plate of the rack is provided with a center control board assembly, a shuffling large board 2 and a scrapper 201, four groups of card picking and carrying systems are arranged around the shuffling large board, each card picking and carrying system comprises a card sending device 3 for picking up mahjong cards one by one and sending out from the shuffling large board, a card pushing device 4 for piling two mahjong cards into one pier and pushing out, and a slope card discharging device for sending the piled mahjong cards along a slope to a table top of the mahjong machine, wherein each slope card discharging device comprises a card feeding assembly 5 and a card lifting assembly 6; the card lifting assembly is arranged on the inner side of the card conveying device in the card picking and conveying system of the same group, and the card lifting assembly and the card conveying device are directly adjacent to each other inside and outside, and in the card picking and conveying system of the same group: 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 on the arc-shaped bending outside of the card storage groove 502, the card feeding driving mechanism of the card lifting push head 505 is arranged on the arc-shaped bending inside of the card storage groove 502, the card feeding inlet of the card feeding device 3 is close to the edge of the card shuffling tray 2, the card discharging opening of the card feeding device 3 is provided with the card carrying table 402 of the card pushing device 4, one side of the card carrying table 402 is the card feeding inlet of the card storage groove 502 in the card lifting assembly, the card discharging opening of the card storage groove 502 is connected with the card feeding opening of the card lifting groove in the card lifting assembly, wherein the card discharging direction of the card feeding device 3 and the card feeding direction of the card lifting assembly 6 form an included angle of 135 DEG to 180 DEG, the card discharging opening of the card feeding device 3 forms an included angle of 80 DEG to 100 DEG with the card discharging direction of the card feeding device 3, the card feeding direction of the card feeding device 502 in the card feeding assembly 5 forms an included angle of 0 DEG to 10 DEG with the card feeding direction of the card feeding device 4, and the card discharging direction of the card storage groove 502 in the card lifting assembly 5 forms an included angle of 0 DEG to 5 DEG with the card discharging direction of the card lifting assembly 6.

When the mahjong machine works, the mahjong shuffling large disc rotates and the mahjong scraping device is not moved, mahjong pieces on the shuffling large disc are respectively pushed to the positions below the mahjong feeding ports of the four mahjong feeding devices at the edge of the shuffling large disc, the mahjong pieces are sucked up by the mahjong sucking wheels in the mahjong feeding devices and are straightened to be in the same direction, and then are fed into the mahjong feeding channel and are fed out from the mahjong outlet of the mahjong feeding channel to a mahjong carrying table in the mahjong pushing device through the conveying belt, as shown in fig. 6; then the piled mahjong pieces are pushed into the mahjong inlet of the mahjong storage groove by the mahjong pushing head in the mahjong pushing device, as shown in figure 7; waiting for a tile feeding signal when sufficient mahjong tiles are stored in a tile storage groove in the tile feeding assembly; when the mahjong machine receives the tile-feeding signal, the tile-feeding supporting plate in the tile-feeding assembly descends, the tile-feeding push head 505 in the tile-feeding assembly pushes out the mahjong tiles in the tile-storing groove to the tile-feeding supporting plate 601 in the tile-feeding assembly for feeding under the drive of the tile-feeding driving mechanism, and after the tile feeding is finished, the tile-feeding supporting plate is lifted upwards to be level with the tabletop of the mahjong machine.

One implementation mode of the mahjong tile arranging method is to adopt disposable tile feeding:

that is, the tile pushing device pushes all mahjong tiles (such as 18 piers in four directions) of one party into the tile storage groove of the tile feeding assembly at one time, and as shown in fig. 8, the tile feeding pushing head 505 is positioned outside the tile inlet of the tile storage groove; when the mahjong machine receives the tile-feeding signal, the tile-feeding supporting plate in the tile-feeding assembly descends, the tile-feeding push head 505 in the tile-feeding assembly pushes out the mahjong tiles in the tile-storing groove to the tile-feeding supporting plate 601 in the tile-feeding assembly for feeding under the drive of the tile-feeding driving mechanism, and after the tile feeding is finished, the tile-feeding supporting plate is lifted upwards to be flush with the tabletop of the mahjong machine as shown in fig. 9.

Another implementation mode of the mahjong tile arranging method is to adopt the steps of tile arranging:

as shown in fig. 12, 13 and 14, an opening through which the card feeding pusher can pass is formed in the outer wall of the card lifting slot of the card lifting assembly. Thus, the mahjong tile is pushed by the tile pushing head which circularly rotates in one direction. As shown in fig. 15, the card-feeding device 3 pushes one mahjong tile 10 onto the tile-carrying block 402; as shown in fig. 16, the tile pushing head 401 pushes one mahjong tile 10 into the tile storing groove 502; as shown in fig. 17, the card-feeding device 3 pushes the second mahjong piece onto the card-holding block 402; as shown in fig. 18, the third mahjong tile is pushed onto the second mahjong tile by the tile sending device 3 to be stacked into a pier; as shown in fig. 19, the tile pushing head 401 pushes a pier of mahjong tiles into the tile storing groove 502; as shown in fig. 20, the tile pushing device repeatedly performs the stacking pushing action, and pushes the six-pier half mahjong tiles into the tile storage groove 502 in sequence; as shown in fig. 21, the tile loading pusher 505 starts pushing the mahjong tiles in the tile storage slot 502; as shown in fig. 22, the tile-pushing head 505 pushes the mahjong tiles to a position close to the outlet in the tile storage slot; as shown in fig. 23, the tile pushing device begins to stack and push the mahjong tiles and pushes a pier of mahjong tiles into the tile storage groove 502; as shown in fig. 24, after the mahjong pieces are fully stored in the mahjong storage groove, the mahjong machine receives the first mahjong piece feeding signal, and then the mahjong piece lifting supporting plate 601 descends; as shown in fig. 25, the tile-feeding pusher 505 sends the front six-pier half mahjong tile to the table top along the tile-lifting supporting plate; as shown in fig. 26, the tile lifting supporting plate 601 is lifted to be flat with the table top, and the six-pier half mahjong tile is sent to the table top; as shown in fig. 27, the card-feeding pusher 505 is turned back out of the card-feeding port of the card-storing slot through the opening on the side wall of the card-lifting slot; as shown in fig. 28, when the mahjong machine receives the second tile feeding signal, the tile lifting supporting plate 601 descends again, and the tile feeding push head 505 starts pushing the remaining mahjong tiles in the tile storage groove; as shown in fig. 29, the tile-feeding pusher 505 sends the remaining mahjong tiles in the tile-storing groove to the table top along the tile-lifting supporting plate; as shown in fig. 30, the tile lifting supporting plate 601 is lifted to be flat with the table top, and the rest mahjong tiles in the tile storage groove are sent to the table top; as shown in fig. 31, the card pusher 505 is rotated back to the home position through an opening in the side wall of the card slot.

The method of arranging the mahjong tiles in stages is not limited to the six-pier half mahjong tiles, but can be to arrange thirteen mahjong tiles in a row (namely, thirteen mahjong tiles are arranged in a row instead of being stacked in one pier up and down), and when the thirteen mahjong tiles are arranged in a row, the tile pushing device only pushes a single mahjong tile into the tile storage groove instead of stacking two mahjong tiles into one pier and pushing the two mahjong tiles into the tile storage groove. There are various forms of how to push a single mahjong tile on the existing tile pushing device in the stacking pushing mode, for example: the card bearing block of the card pushing device stops moving to push cards into the card storage groove only by the movement of the card pushing head; or, although the tile bearing block moves up and down, the tile feeding device waits for the tile pushing head to push away one tile and then feeds out the next tile after feeding out one tile to the tile bearing block; or, the thirteen mahjong tiles on the first are pushed by the tile pushing head to be sent into the tile storage groove, and the rest mahjong tiles on each side are stacked into a pier by the tile pushing device to be sent into the tile discharge storage groove, so that the structure is simple, and the action is reasonable.

The card feeding bracket 501 is provided with a sensor 504 for detecting the position state of the card feeding push rod 503 or the card feeding push head 505 and/or the mahjong playing card: in the card feeding assembly adopting the disposable card feeding method, as shown in fig. 5, at least two sensors are needed and are respectively used for detecting and obtaining the position information when the card feeding push head stays outside the card feeding port of the card storage groove and waits for pushing a card, and the position information when the card feeding push head stays outside the card discharging port of the card storage groove and waits for lifting the card supporting plate to lift the mahjong card on the table top; in the card feeding assembly adopting the staged card feeding method, at least three sensors are required and are respectively used for detecting and obtaining the position information (shown in fig. 15-20, 27 and 31, the first sensor 5041) when the card feeding head stays outside the card inlet of the card storage groove and waits for pushing cards, the position information (shown in fig. 22-24) when the card feeding head stays in the card storage groove and waits for the first card feeding signal, the third sensor 5043) and the position information (shown in fig. 25, 26, 29 and 30) when the card feeding head stays in the card outlet of the card storage groove and waits for the card lifting supporting plate to lift the mahjong on the table surface. The accurate position of the card feeding push head is determined through the sensor, and the card feeding push head is fed back in time, is convenient to control, acts accurately and reduces faults.

Preferably, a sensor for detecting mahjong pieces or a pushing head of the mahjong pieces can be arranged at the mahjong piece inlet and/or the mahjong piece outlet of the mahjong piece storage groove, such as a second sensor 5042 and a fifth sensor 5045 in fig. 21, 28 and 30. The sensor for detecting the card pushing head can be in a direct detection mode or an indirect detection mode, for example, the driving mechanism of the card pushing head is subjected to position detection to obtain corresponding position information of the card pushing head, for example, the position information of the card pushing rod is detected to obtain the position information of the card pushing head, for example, a stepping motor or a motor with a position sensor is adopted, and the position information of the card pushing head is converted by recording the rotation travel information of the motor. The sensor may be a hall sensor, a photoelectric sensor, an ultrasonic sensor, or a contact sensor such as a limit switch.

The first card-up signal is typically generated by the player pressing a control button. The second card feeding signal may be generated by the player pressing a control button, or may be generated by a sensor capable of detecting whether the player removes the mahjong on the card lifting board, for example, as shown in fig. 32 and 33, the sensor may be an optical eye 6011 or a gravity sensor provided on the card lifting board 601, or another sensor provided on a table or a card lifting stand for detecting the action state and/or the load-bearing state of the card lifting board.

Example 2:

in the embodiment 1, the tile pushing device with the stacking and pushing function (stacking and pushing out two mahjong tiles into one pier) is adopted, and in the embodiment, the tile stacking device for stacking two mahjong tiles into one pier and the tile pushing device for pushing the mahjong tiles stacked into one pier into the tile storage groove are two relatively independent devices. The specific structure of this embodiment is as follows:

the utility model provides an automatic mahjong machine, includes central control board subassembly 1, shuffling tray 2 and the scraper 201 that are located frame bottom plate central authorities, is provided with four sets of card pick-up handling systems around shuffling tray, card pick-up handling system includes the card device that is used for picking up mahjong pieces and send out from shuffling tray one by one, is used for piling up two mahjong pieces and piles the card device of mound, is used for pushing the mahjong pieces of piling up into the mahjong piece pushing device of storing up the mound and is used for sending the slope play device of mahjong pieces of mound along the slope in the storing up the mahjong machine desktop, slope play device includes card subassembly 5 and rises card subassembly 6.

As shown in fig. 42-50, the stacking device for stacking two mahjong tiles into a pier comprises a tile bearing conveyer belt 302 arranged on a tile bearing support, the conveying direction of the tile bearing conveyer belt 302 is basically consistent with that of a tile conveying conveyer belt 301, the tile bearing conveyer belt 302 is arranged below a tile outlet of the tile conveying device, the tile bearing surface of the tile bearing conveyer belt 302 is lower than the tile outlet of the tile conveying device by about one mahjong tile thickness, a tile blocking piece 304 and a side blocking piece are arranged near the tile bearing conveyer belt 302, the tile outlet of the tile conveying device and the tile blocking piece 304 are respectively arranged on two opposite sides of the tile bearing conveyer belt 302, and the side blocking piece and the tile pushing-out opening of the mahjong tile are respectively arranged on two opposite sides of the tile bearing conveyer belt 302. The card feed detecting device for detecting whether or not the card feed outlet of the card feed device feeds out mahjong tiles onto the card bearing conveyer belt can be arranged on the card blocking piece, but is preferably arranged on the side blocking piece so as to improve the detection precision and reliability.

The card stacking principle of the card stacking device is as follows: the first mahjong tile is sent out from the tile outlet of the tile sending channel, because the tile carrying conveying belt 302 is lower than the tile sending conveying belt 301, when the first mahjong tile is sent out from the tile outlet and exceeds half of the tile sending conveying belt, the front end of the first mahjong tile falls onto the tile carrying conveying belt under the action of self gravity, along with the conveying of the tile carrying conveying belt, the rear end of the first mahjong tile also falls onto the tile carrying conveying belt, after the first mahjong tile falls onto the tile carrying conveying belt 302 and is blocked by the blocking piece and cannot move, the second mahjong tile continues to move towards the tile carrying conveying belt, and because the height difference between the tile carrying conveying belt and the tile sending conveying belt is larger than the mahjong tile thickness, the second mahjong tile is directly stacked on the first mahjong tile, so that the stacking of one pier of mahjong tiles is realized.

The power source for the card carrier belt 302 may be in various embodiments:

in the first embodiment, the card carrying conveyor belt 302 and the card feeding conveyor belt 301 are the same conveyor belt, and as shown in fig. 42, 43 and 44, a plurality of conveying pulleys are arranged below the card discharging wheel of the card feeding device so that the conveyor belt is wound to form the card carrying conveyor belt 302, and thus the rotation rates of the card carrying conveyor belt 302 and the card feeding conveyor belt 301 are consistent and are driven by the card feeding motor 305.

In the second embodiment, the card carrying conveyer belt 302 and the card feeding conveyer belt 301 are two conveyer belts which are respectively and independently wound, and the card carrying conveyer belt 302 is in transmission connection with a conveyer belt wheel or a card feeding motor of the card feeding conveyer belt 301 through a transmission part 311, as shown in fig. 45, 46 and 47, the card carrying conveyer belt 302 is independently wound on the conveyer belt wheels, and one of the conveyer belt wheels is connected with the card feeding motor 305 through the transmission belt.

In the third embodiment, the card carrying conveyer 302 and the card delivering conveyer 301 are two conveyer belts which are respectively and independently wound, and the power of the card carrying conveyer 302 is derived from the shuffling tray 2, as shown in fig. 48, 49, 50 and 51, one conveyer belt wheel of the card carrying conveyer 302 is in gear transmission connection with the shuffling tray 2 through the staggered shaft transmission assembly 313 and the gear 312, so that the position and the structure of the card stacking device are more flexible. The staggered shaft drive assembly 313 herein may be a bevel gear set or a worm gear or the like with a similar drive mechanism.

There are a number of arrangements for mounting the card holders 310 of the card transport belt 302: the card holder 310 may be integrally manufactured with or fixedly attached to the card shoe inner housing 307 and/or the card shoe outer housing 306 of the card feed device 3, as shown in fig. 42 to 50; alternatively, the tile-bearing support 310 is independently fixed on the bottom plate of the mahjong machine; further, the card holder 310 may be integrally formed with or fixedly connected to a card holder provided with a card storage slot.

The card retainer 304 may be integrally formed with or fixedly connected to the card holder 310, or may be integrally formed with or fixedly connected to a card-feeding housing having a card-storing slot.

The side blocking pieces and the pushing-out openings of the mahjong tiles are respectively positioned on two opposite sides of the tile carrying conveying belt 302, and the side blocking pieces are arranged to limit the first mahjong tile stacked on one side of the tile pushing-out so as to limit the first mahjong tile to move towards one side of the tile pushing-out, so that the problems that the two stacked mahjong tiles are not flush up and down and fall off and are blocked in the tile pushing-out process can be avoided. The side guard may be a fixed part (fixed side guard 303) that may be integrally formed with or fixedly connected to the card holder 310, may be integrally formed with or fixedly connected to the card holder provided with the card slot, and may be integrally formed with or fixedly connected to the card shoe inner housing. The side stop may also be a movable part, such as a pusher that pushes the mahjong tile out of the tile carrying conveyor. Preferably, the fixed side stop 303 in the form of a fixed part has a better limit effect and reliability.

In order to directly push the mahjong tiles on the tile bearing conveyer belt 302 into the tile storage groove of the tile loading assembly through the push head, the problem of deflection of the conveyer belt caused by pushing the mahjong tiles along the conveying direction of the vertical conveyer belt is avoided as much as possible, a stop edge or a groove for limiting the deflection of the conveyer belt is arranged on a conveyer belt wheel and/or a tensioning wheel 308 of the coiling tile bearing conveyer belt 302, and a bearing platform and an opening for the tile bearing conveyer belt to pass through and wind can be arranged on the tile bearing support, wherein the bearing platform is positioned below the tile bearing surface of the tile bearing conveyer belt 302, and the opening can limit the position of the tile bearing conveyer belt to reduce the deflection.

The mahjong machine adopts the structure without the card turning device and the stacking machine head, thereby greatly reducing the height and the manufacturing cost of the main machine of the mahjong machine.

The tile feeding assembly is shown in fig. 34, 55, 57, 58 and 59, and comprises a tile feeding support 501, wherein a tile storage groove 502 for storing a plurality of pieces of mahjong tiles and a tile feeding push head 505 for pushing the mahjong tiles out of the tile storage groove 502 are arranged on the tile feeding support 501, the tile storage groove 502 is curved in an arc shape, the bending angle is larger than 180 degrees, the tile feeding direction of a tile feeding opening on the tile storage groove 502 forms an included angle of 45-90 degrees with the tile discharging direction of a tile discharging opening, and the tile feeding push head 505 is driven by a tile feeding driving mechanism to move from the outside of the tile feeding opening of the tile storage groove 502 to the outside of the tile discharging opening of the tile storage groove 502 along the tile storage groove 502 and then returns to the outside of the tile feeding opening of the tile storage groove 502.

The card feeding driving mechanism can be in various forms, such as a wire rope traction mechanism, a chain traction mechanism, a deflector rod transmission mechanism, a gear transmission mechanism, a cam transmission mechanism and the like. In this embodiment, as shown in fig. 34 and 52, the card feeding driving mechanism is a card feeding push rod 503 rotating around a fixed point, and the card feeding push head 505 is mounted on the card feeding push rod 503. The card feeding push rod 503 can be directly fixed on the output shaft of the card feeding motor 506, or the card feeding push rod 503 is in transmission connection with the card feeding motor 506 through a transmission mechanism. The card feeding push rod 503 may swing back and forth or rotate in a single direction, as shown in fig. 52 and 53, so that an opening 604 through which the card feeding push head and the card feeding push rod can pass is formed on the outer side wall 602 of the card feeding slot 603 of the card feeding assembly 6, and the opening is in an inverted L shape. The card feeding bracket 501 is provided with a sensor 504 for detecting the position state of the card feeding push rod 503 or the card feeding push head 505. The single push rod is adopted to push the cards, the rotation center of the card feeding push rod is concentric with the arc bending center of the card storage groove, so that the direction of the pushing force is basically in the arc tangential direction and is basically coincident with the movement direction, the pushing force is smaller (component force is reduced) under the same shape, the motor load is smaller, and the reliability is better.

In order to further extend the length of the card slot and simultaneously minimize the card pushing resistance of the card feeding pusher, as shown in fig. 34, the card slot has a first arc-shaped card storage portion 5021 and a second arc-shaped card storage portion 5022, the first arc-shaped card storage portion 5021 is close to the card inlet of the card slot, the second arc-shaped card storage portion 5022 is close to the card outlet of the card slot, the bending radius of the second arc-shaped card storage portion 5022 is greater than that of the first arc-shaped card storage portion 5021, and the bending angle of the second arc-shaped card storage portion 5022 is not less than 180 °. In order to minimize the tile pushing resistance of the tile pushing head and ensure that the tile wall of the table top of the mahjong machine is tidy and not messy, the second circular arc tile storage part 5022 is directly communicated with the tile inlet of the tile lifting assembly, and the tile inlet direction of the tile lifting assembly is consistent with the tangential direction of the second circular arc tile storage part 5022. In order to ensure smooth and rapid tile pushing, reduce the load of the tile feeding motor, and facilitate the fixed connection of the tile feeding pushing head and the tile feeding pushing rod, it is preferable that the difference of the bending radius of the second circular arc tile storage part 5022 and the first circular arc tile storage part 5021 is smaller than the length of one mahjong tile.

In order to ensure that the tile pushing head 505 can always be positioned in the tile storage groove 502, the tile pushing position of the tile pushing head 505 cannot be thicker, that is, the tile pushing position of the tile pushing head 505 on the tile inlet and the tile outlet of the tile storage groove can be changed greatly, so that the tile pushing head 505 only has the problem of larger resistance when pushing the tile in the tile storage groove 502, but because the tile storage groove side wall of the tile storage groove is not well limited and blocked by the upper tile and the lower tile stacked on the tile bearing conveyor belt, the tile pushing head 505 rotating around the fixing point is positioned more outwards than the tile storage groove, so that the tile pushing head 505 can easily push the tile in the tile storage groove and can not be pushed into the tile storage groove in a inclined manner when pushing the tile on the tile bearing conveyor belt.

To solve this problem, as shown in fig. 54 and 55, in one embodiment, the card-pushing head 505 has a first pushing head 5051 and a second pushing head 5052, when the card-pushing rod 503 and the card-pushing head 505 rotate around a fixed point, the first pushing head 5051 and the second pushing head 5052 have different radii of rotation inside and outside, so as to push the mahjong pieces respectively or jointly, as shown in fig. 55, the card-pushing support 501 is provided with a pushing head slot 508 inside the card-storing slot 502, when the card-pushing head 505 is outside the card-feeding opening of the card-storing slot 502 (i.e. above the card-carrying conveyer 302), the mahjong pieces are pushed jointly by the first pushing head 5051 and the second pushing head 5052 or are pushed mainly by the second pushing head 5052, and when the card-pushing head 505 enters the card-feeding slot 502, the second pushing head 5052 enters the card-pushing slot 508, and the first pushing head 5051 pushes the mahjong pieces in the card-storing slot 502. Thus, the second pushing head 5052 can better and flexibly set the relative tile pushing position of the second pushing head 5052 and the mahjong tile only when pushing the mahjong tile into the tile inlet of the tile storage groove 502 from the tile bearing conveyor belt, so that better tile pushing effect is achieved, and the situation that the folded mahjong tile on the tile bearing conveyor belt is inclined, blocked and cannot be pushed into the tile storage groove is avoided. In this process, the first push head 5051 can perform a good auxiliary function.

In order to avoid the corners of the mahjong pieces from being blocked in the pushing head groove 508, the bottom of the inlet of the pushing head groove 508 is higher than the bottom of the tile storage groove 502 to block the lower mahjong pieces from being blocked, and a blocking piece 509 is arranged at the upper part of the inlet of the pushing head groove 508 to block the upper mahjong pieces from being blocked, and correspondingly, the second pushing head 5052 can also be bent and shaped so as to enter the pushing head groove 508 through the blocking piece 509.

In another embodiment, as shown in fig. 56 and 57, the tile feeding driving mechanism includes a tile feeding slider seat 511, a tile feeding slider 510 and a tile feeding push rod 503 mounted on the tile feeding support 501, the tile feeding slider seat 511 is driven by the tile feeding motor 506 to rotate around a fixed point, the tile feeding slider 510 is slidably connected with the tile feeding slider seat 511, the tile feeding push rod 503 is fixedly connected with the tile feeding slider 510 or integrally manufactured, the tile feeding push rod 505 is mounted on the tile feeding push rod 503, and the tile feeding support 501 is provided with a cam groove 512 matched with the tile feeding slider 510, so that the tile feeding slider 510 drives the tile feeding push rod 503 to move under the cam curve control of the cam groove 512 in the process of driving the tile feeding push rod 503 to realize the position adjustment of the tile feeding push rod 505 on the tile feeding push rod 503, thereby always having good tile feeding effect, and avoiding the problems that the tile feeding push rod 505 is inclined, jammed and cannot be pushed into the storage groove when pushing the tile on the tile feeding conveyor belt.

In addition, under the condition of permission, the whole circular arc-shaped tile storage groove 502 can be adopted, as shown in fig. 58 and 59, the tile storage groove 502 is a whole circular arc, so that the tile pushing position of the tile pushing head 505 on the tile inlet and the tile outlet of the tile storage groove does not need to be changed, the tile pushing head 505 can still rotate around a fixed point to have more contact position selection and larger contact area with the tile, and good tile pushing effect can be ensured no matter the tile on the tile carrying and conveying belt is pushed or the tile in the tile storage groove is pushed, and the problem that the tile is blocked or cannot be pushed into the tile storage groove does not occur. Of course, the overall circular arc shaped card slot 502 is more suitable for card feeding assemblies that employ staged card feeding methods, as the length of the card slot of the staged card feeding method may be shorter.

The tile pushing device for pushing the mahjong tiles stacked on the tile bearing conveying belt into the tile storage groove can be the movable side blocking piece, namely a relatively independent pushing head for pushing the mahjong tiles out of the tile bearing conveying belt or a tile pushing head 505 in the tile feeding assembly, so that the tile pushing head 505 is stopped at the opposite side of the mahjong tile pushing outlet of the tile bearing conveying belt, and the tile pushing head 505 has two action functions: firstly, when the mahjong tiles are stored in the tile storage groove, the tile feeding pushing head pushes the mahjong tiles stacked into one pier on the tile bearing conveying belt into the tile inlet of the tile storage groove, and then returns to continue pushing the mahjong tiles of the next pier until the mahjong tiles are fully stored in the tile storage groove; secondly, after the mahjong tiles are fully stored in the tile storage groove and the tile feeding signals are received, the tile feeding pushing head sends the mahjong tiles with multiple piers in the tile storage groove to the table top of the mahjong machine along the inclined tile lifting supporting plate.
