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.

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.

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.

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.

The utility model provides a put on tablet subassembly that publication number is CN107233724 etc. serial application patent document discloses, includes the support of putting on the tablet, is equipped with the storage tank that is used for storing many mounds mahjong pieces on the support of putting on the tablet and is used for pushing out the last tablet of this storage tank and pushes away the head, and this storage tank is arc crooked and bending angle is greater than 180, and the direction of advancing of the last inlet of this storage tank is 45 to 90 contained angles with the direction of coming out of the outlet, go up the tablet and push away the head and drive from the outer inlet of storage tank along the storage tank of card driving mechanism and remove to the outlet of storage tank outside the inlet of storage tank again.

The card feeding channel can be a traditional straight channel, but an arc card feeding channel can be selected according to the requirement of 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.

In one embodiment, the tile pushing device 4 is capable of stacking and pushing (stacking and pushing out two or more mahjong tiles in a pier) and comprises a tile pushing head and a tile bearing table. For a specific structure of the card pushing device, reference may be made to patent documents such as CN201906453U, CN201949619U, CN103861280a and CN204699375U, CN 101987247. 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 the number of pushing cards, a card blocking frame is arranged near the card bearing table, 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, one side of the card bearing table 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 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.

In another embodiment, the stacking means for stacking the tiles into a pier and the pushing means for pushing the stacked tiles into the tile storage slot are two relatively independent means. In order to save the cost of the motor, the card stacking device and the card feeding device may be combined, for example, the structure disclosed in patent document such as CN105903186A, CN205699378U, CN205699375U, CN205832557U, CN107233724 series application: the mahjong stacking device comprises a mahjong carrying conveyer belt arranged on a mahjong carrying support, wherein the conveying direction of the mahjong carrying conveyer belt is basically consistent with that of a mahjong carrying conveyer belt, the mahjong carrying conveyer belt is arranged below a mahjong outlet of the mahjong carrying device, the mahjong carrying surface of the mahjong carrying conveyer belt is lower than the mahjong outlet of the mahjong carrying device by about one mahjong piece in thickness, a mahjong blocking piece and a side blocking piece are arranged near the mahjong carrying conveyer belt, the mahjong outlet of the mahjong carrying device and the mahjong blocking piece are respectively positioned on two opposite sides of the mahjong carrying conveyer belt, and the side blocking piece and a mahjong pushing opening of the mahjong are respectively positioned on two opposite sides of the mahjong carrying conveyer belt. 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 is lower than the tile sending conveying belt, 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, the rear end of the first mahjong tile also falls onto the tile carrying conveying belt along with the conveying of the tile carrying conveying belt, and after the first mahjong tile falls onto the tile carrying conveying belt 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 tile thickness, the second mahjong tile is directly stacked on the first mahjong tile, so that the stacking of one pier of mahjong tile is realized. The stacking principle of the three mahjong pieces is similar.

There are various embodiments of the power source for the card-bearing conveyor belt: the first implementation mode is that the card bearing conveyer belt and the card conveying conveyer belt are the same conveyer belt, and a plurality of conveyer belt wheels are arranged below the card discharging wheels of the card conveying device so that the conveyer belt is wound to form the card bearing conveyer belt, and therefore, the rotation rates of the card bearing conveyer belt and the card conveying conveyer belt are consistent and are driven by the card conveying motor. The second implementation mode is that the card bearing conveyer belt and the card conveying conveyer belt are two conveyer belts which are respectively and independently wound, and the card bearing conveyer belt is in transmission connection with a conveyer belt wheel of the card conveying conveyer belt or a card conveying motor through a transmission part. The third implementation mode is that the card bearing conveyer belt and the card conveying conveyer belt are two conveyer belts which are respectively and independently wound, and the power of the card bearing conveyer belt is derived from a large card shuffling tray, so that the position and the structure of the card stacking device are more flexible.

A hold tablet support for installing hold tablet conveyer belt can have multiple setting methods: the card bearing bracket is integrally manufactured or fixedly connected with the card feeding box inner shell and/or the card feeding box outer shell of the card feeding device; or the tile supporting bracket is independently fixed on the bottom plate of the mahjong machine; furthermore, the card bearing bracket can be integrally manufactured or fixedly connected with the card feeding bracket provided with the card storage groove.

The tile pushing device for pushing the piled mahjong tiles into the tile storing groove can be a separate tile pushing device, such as the tile pushing head and the driving mechanism thereof in the previous embodiment. In a preferred form, this function is achieved using a card pusher in the card assembly.

The tile feeding assembly comprises a tile feeding support 501, 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 5021 on the tile storage groove 502 and the tile discharging direction of a tile discharging opening 5022 are included angles of 45 degrees to 90 degrees, and the tile feeding push head 505 is driven by a tile feeding driving mechanism to move from the tile feeding opening of the tile storage groove 502 to the tile discharging opening of the tile storage groove 502 along the tile storage groove 502 and then return to the outside of the tile feeding opening of the tile storage groove 502. The card pusher 505 may be moved back and forth along the card slot or may be moved in a single direction in a circular manner.

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. As shown in fig. 3, the table top 1 of the mahjong machine is provided with a tile lifting opening 111 matched with the tile lifting supporting plate 601.

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:

1. the card sending device and the card lifting assembly in the same group of card picking and carrying systems are directly adjacent to each other inside and outside, so that the card storage groove is curved in a large-angle arc shape, the length of the card storage groove is prolonged, and the storage quantity of mahjong tiles in the card storage groove is increased.

2. The card lifting assembly and the card feeding device in the same group of card picking and conveying systems are arranged outside the arc-shaped bending of the card storage groove, and the card lifting driving mechanism of the card lifting pushing head is arranged inside the arc-shaped bending of the card storage groove, so that the card lifting assembly and the card feeding device are not overlapped up and down, and the card feeding device and the card lifting assembly are not overlapped up and down, or only the card outlet end of the card lifting assembly and the card feeding device are overlapped in a small amount, the problem that the height of the mahjong machine is obviously increased due to the up-down overlapping of the related device assemblies caused by the mutual staggered arrangement between the adjacent card picking and conveying systems in the prior art is avoided, and compared with the prior art, the machine with the card storage groove overlapped on the card feeding device, the integral height of the machine can be correspondingly reduced.

3. The card lifting assembly and the card feeding device in the same group of card picking and conveying system are arranged outside the arc-shaped bending of the card storage groove, and the card feeding driving mechanism of the card feeding pushing head is arranged inside the arc-shaped bending of the card storage groove, so that the arc-shaped bending of the card storage groove is closer to the arc, the card feeding driving mechanism drives the card feeding pushing head to move in the card storage groove to push cards, the resistance of the card feeding driving mechanism to move is smaller, the acting force required to be applied at each stage of movement is more uniform, and therefore, the motor load of the card feeding driving mechanism is smaller, the transmission structure is simpler, the reliability is better, and the manufacturing cost and the use and maintenance cost are reduced.

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, four sets of card picking and carrying systems are respectively and independently arranged, larger space can be reserved between two adjacent card feeding assemblies, so that a control main board, a transformer, a large disc motor and the like which are originally placed in an electric box below a bottom plate of the mahjong machine can be placed at a gap between two card feeding assemblies on the periphery of a shuffling large disc, the electric box can be smaller and thinner, the electric box can be removed in a central control structure scheme using a side-hung door structure, the height and manufacturing cost of a main machine of the mahjong machine are greatly reduced, and the electric box in the mahjong machine with a four-foot structure can be 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 have various forms, such as a steel wire rope traction mechanism, a chain traction mechanism, a deflector rod transmission mechanism, a gear transmission mechanism, a cam transmission mechanism and the like:

for example, a movable connection structure of a turntable and a card pushing head is disclosed in a series of patent application publication numbers CN106166379, in the structure, a card pushing block is inserted on an annular vertical rail and slides to push cards, the annular vertical rail is composed of a circular arc section and a straight line section, and the card pushing block is driven by the turntable to reciprocate in a 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.

For example, the card feeding assembly disclosed in the patent document of the series application with the publication number of CN107233724 comprises a card feeding support, a card storage groove for storing a plurality of piers of mahjong tiles and a card feeding push head for pushing the mahjong tiles out of the card storage groove are arranged on the card feeding support, the card storage groove is curved in an arc shape, the bending angle is larger than 180 degrees, the card feeding direction of a card feeding port on the card storage groove forms an included angle of 45-90 degrees with the card discharging direction of a card discharging port, and the card feeding push head is driven by a card feeding driving mechanism to move from the outside of the card feeding port of the card storage groove to the outside of the card feeding port of the card storage groove along the card storage groove and then returns to the outside of the card feeding port of the card storage groove. The card feeding pushing head can move back and forth along the card storage groove or move circularly in a single direction. The card feeding driving mechanism is a card feeding push rod which rotates around a fixed point, the card feeding push head is arranged on the card feeding push rod, and the card feeding push rod is in transmission connection with the card feeding motor. The card feeding driving mechanism adopts a single push rod structure, the rotation center of the card feeding push rod is concentric with the arc bending center of the card storage groove, the card pushing head positioned in the card storage groove does not need a track or is in contact with the inner wall of the card storage groove, and the friction resistance of the card pushing head in movement is reduced.

In the invention, the card feeding driving mechanism adopts a chain traction mechanism.

The slope card discharging device as shown in fig. 5 and 14 comprises a card lifting assembly and a card feeding assembly, wherein the card feeding assembly comprises a card feeding bracket 501, a card storage groove 502 for storing a plurality of piers of mahjong tiles and a card feeding push head 505 for pushing the mahjong tiles out of the card storage groove 502 are arranged on the card feeding bracket 501, the card storage groove 502 is curved in an arc shape, the bending angle is larger than 180 degrees, the card feeding direction of a card feeding port 5021 on the card storage groove 502 forms an included angle of 45 degrees to 90 degrees with the card discharging direction of a card discharging port 5022, and the card feeding push head 505 is driven by a card feeding driving mechanism to move from the outside of the card feeding port of the card storage groove 502 to the outside of the card feeding port of the card storage groove 502 along the card discharging port of the card storage groove 502 and then returns to the outside of the card feeding port of the card storage groove 502. The card pusher 505 may be moved back and forth along the card slot or may be moved in a single direction in a circular manner. The tile feeding driving mechanism comprises a tile feeding chain 503 and a tile feeding chain wheel, the tile feeding push head 505 is arranged on the tile feeding chain 503, the chain length of the tile feeding chain 503 is larger than the total length of mahjong tiles stored in the tile storage groove, the running track of the tile feeding chain 503 is matched with the running track of mahjong tiles in the tile storage groove, and the tile feeding chain wheel is in transmission connection with the tile feeding motor.

The tile feeding chain 503 runs along a chain track fixed on the tile feeding bracket 501, and the chain track can be formed by a plurality of tensioning chain wheels or transition chain wheels, or can be formed by combining a plurality of transition chain wheels and a track plate, but preferably, the chain track is formed by adopting a fixed chain track groove 5034, so that the running track of the tile feeding chain 503 is more matched with the running track of the mahjong tiles in the tile storage groove. To reduce the running friction of the chain with the track grooves, the inner wall of the chain track groove 5034 may be made of a material with a smooth and wear-resistant surface, such as polyoxymethylene, polytetrafluoroethylene, etc., for example, in the form of a chain track seat with a smooth and wear-resistant surface, which is fixed to the upper plate support. Further preferably, the card feeding chain 503 is in rolling contact with the chain track groove 5034 to reduce running resistance, for example, the rollers on the passing chain links of the card feeding chain 503 are in rolling contact with the chain track groove 5034, as shown in fig. 9 and 12, the cross section of the chain track groove 5034 is T-shaped, and two inner side walls of the chain track groove 5034 extend to form protruding strips which are in rolling contact with the rollers of the card feeding chain 503, in other embodiments, a chain with the outer diameter of the rollers being larger than the width of the link plate can be adopted. In a further preferred embodiment, the rollers of the card feeding chain 503 have a structure with annular grooves on the circumferential surface, and the annular grooves are matched with the convex strips extending from the two inner side walls of the chain track groove 5034, so that the upper and lower limiting is realized while rolling contact, the moving direction and the upper and lower positions of the card feeding chain can be limited to avoid twisting and blocking, and the friction contact between the bottom of the chain and the bottom of the chain track groove can be avoided to increase the running resistance. For the upper card chain 503 to be an open loop chain, the upper and lower limit structure described above is preferably employed to reduce the chain movement resistance and avoid operational failure. For the chain track groove 5034 with a T-shaped cross section, the chain track seat 5033 may be manufactured by using an inner side wall or an outer side wall, and assembled and fixed as a whole. A number of notches are provided in the chain track groove 5034 for the sprocket. The chain track groove 5034 and the chain track seat 5033 are integrally annular to facilitate the circulation of the card feeding chain 503.

In the first embodiment shown in fig. 5, a card feeding chain 503 is installed above the inside of the card slot 502, and the upper portion of the card pusher 505 extends toward the inside of the card slot 502 and is fixed to the links of the card feeding chain 503. The structure is simple and reasonable, and the transformation is convenient relative to the existing equipment.

The mounting manner of the card feeding chain in the embodiment can be as follows:

1. as shown in fig. 6 and 7, the card feeding chain 503 is a closed loop chain, and is integrally connected end to end, only one driving card feeding chain wheel, namely a second chain wheel 5032 is needed, and a tensioning chain wheel, namely a first chain wheel 5031, can be arranged for tensioning the card feeding chain 503; thus, the card feeding chain 503 can drive the card feeding pusher 505 to reciprocate along the card storage slot or circularly move in one direction.

2. As shown in fig. 8 and 10, the card feeding chain 503 is an open loop chain, and is not connected end to end, but adopts a double card feeding chain wheel structure, namely, a first chain wheel 5031 and a second chain wheel 5032 are in transmission connection with a card feeding motor 506 through gears, so that the card feeding chain 503 can drive a card feeding push head 505 to reciprocate along a card storage groove or circularly move in a single direction.

3. As shown in fig. 11 and 12, the card feeding chain 503 is an open loop chain, and is not connected end to end, and only one card feeding chain wheel which is driven by driving is adopted, namely a second chain wheel 5032, and the first chain wheel 5031 is a tensioning chain wheel for tensioning the card feeding chain 503, so that the card feeding chain 503 can only drive the card feeding push head 505 to reciprocate along the card storage groove.

In the open loop chain, the card pushing head is preferably arranged at the middle position of the card feeding chain, so that the front pushing and back pulling operation resistance is small.

In a second embodiment, shown in figures 13 and 14, a card-feeding chain 503 is mounted under the card-holding groove 502, and the lower part of the card-feeding pusher 505 passes down through a slot in the bottom of the card-holding groove 502 and is fixed to a link of the card-feeding chain 503. The mounting mode of the card feeding chain of this embodiment may be the same as that of the previous embodiment. A chain track block 5033 having a chain track slot 5034 is mounted to the bottom of the card slot 502. Therefore, the installation of the card feeding chain is abundant, and the pushing force of the card feeding pushing head is larger and the operation is stable. However, in this embodiment, a deck or a deck conveyor belt driven by a chain is required, and for example, a deck pusher of a deck having a flap structure disclosed in patent document CN202446788U is required. That is, the support board for receiving the mahjong pieces outside the outlet of the feeding device is in the form of a support board which can be turned over along one side, and is used as a part or an extension part of the support board or the support conveyer belt, when the feeding device feeds the mahjong pieces onto the support board or the support conveyer belt, the support board shields the chain track groove to avoid the mahjong pieces from being broken down, and when the mahjong pieces are required to be pushed by the upper push head, the support board is turned over to one side to pass by the upper push head.

In the third embodiment of the present invention, the card feeding chain 503 is installed below or in the middle of the inner side of the card storing groove 502, and an opening is formed on the inner side wall of the card storing groove 502 to allow the card feeding pusher 505 in the card storing groove to extend to the inner side of the card storing groove 502 and be fixed on the chain link of the card feeding chain 503. Therefore, the installation of the card feeding chain is abundant, and the pushing force of the card feeding pushing head is larger and the operation is stable. However, in this embodiment, the inner side wall of the card slot needs to be grooved, or all or part of the inner side wall of the card slot needs to be manufactured separately and then assembled on the card feeding bracket, or the inner side wall of the card slot may be fixed or integrally formed on the cover of the card slot, and then the cover is fixed on the card feeding bracket. The mounting mode of the card feeding chain of this embodiment may be the same as that of the previous embodiment. A chain track mount 5033 having a chain track slot 5034 is mounted inside the card holding slot 502 or integrally formed with the card feeding bracket.

In other embodiments, the card-feeding pusher may move along a track, the card-feeding chain may be movably connected to the card-feeding pusher, for example, by a pin and a kidney-shaped hole to realize movable connection and transfer of pushing force, and the track may be disposed on an inner side wall, an outer side wall, or a bottom of the card-storing slot. The mounting mode of the card feeding chain can be the same as the embodiment. The card feeding chain can also be replaced by a steel wire rope, and correspondingly, the card feeding chain wheel is replaced by a steel wire rope driving wheel.

In other embodiments, the card feeding chain and the driving mechanism thereof can be arranged outside the card storage groove. The mounting mode of the card feeding chain can be the same as the embodiment.

The card storage slot may be circular arc-shaped or may be formed by splicing a plurality of circular arc slot sections, and in order to further extend the length of the card storage slot, as shown in fig. 16, it is preferable to splice a plurality of straight slot sections 5023 and a plurality of circular arc slot sections 5024.

In addition, under the condition of permission, the storage groove 502 which is arc-shaped is preferably adopted, and the storage groove 502 is an entire arc, so that the position of the tile pushing head 505 for pushing the mahjong tiles at the tile inlet and the tile outlet of the storage groove is not required to be changed, the tile pushing head 505 can still rotate around the fixed point to have more contact position selection with the mahjong tiles, and has larger contact area, so that good tile pushing effect can be ensured no matter the mahjong tiles on the tile bearing table or the tile bearing conveying belt are pushed or the mahjong tiles in the storage groove are pushed, and the problem that the mahjong tiles are blocked or cannot be pushed into the storage groove can be avoided. 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.

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 of mahjong tiles in the tile storage groove in the tile pushing process of the tile pushing device, a cover 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. The inner side wall and/or the outer side wall of the tile storage groove can be integrally formed with the tile feeding bracket, can be independently manufactured and then fixed on the tile feeding bracket to be connected as a whole, and can be integrally formed with or fixedly connected with the cover cap of the tile storage groove, and the inner side wall and/or the outer side wall of the tile storage groove are arranged on the cover cap so that the width of the tile storage groove can be conveniently changed by changing the cover cap to be suitable for mahjong tiles with different sizes.

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.

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.

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 tile machine adopting the tile pushing device 4 capable of realizing the tile stacking and pushing functions comprises the following steps:

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

namely, 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 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 level with the tabletop of the mahjong machine.

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

wherein, open and can go up the avoiding opening that the tablet pushing head passed through on rising the lateral wall of tablet groove of card subassembly. Thus, the mahjong tile is pushed by the tile pushing head which circularly rotates in one direction. 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 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.
