The mahjong tiles are stacked conveniently, and the mahjong tiles are stacked conveniently. Obviously, the height difference between the carrying table and the delivery path should be comparable to the thickness of one mahjong tile (for stacking two mahjong tiles) or to the thickness of two mahjong tiles (for stacking three mahjong tiles).

In addition, the conveyer belt of the invention not only runs in the conveying channel, but also runs on the surface of the tile bearing table, and the conveyer belt extends to the surface of the tile bearing table, so that the inertial impact between the mahjong tiles falling from the conveying channel and the surface of the tile bearing table is relieved, and the tile planting is avoided.

The invention organically combines the card taking and conveying unit and the card stacking unit by utilizing the conveying belt, realizes that the large-disc driving motor drives the card shuffling and card taking actions and simultaneously drives the card stacking actions, and avoids arranging an additional driving mechanism to drive the card stacking unit.

In the multi-mechanism combined driving device of the roller coaster type full-automatic mahjong machine, reversing wheels and second conveying wheels are respectively arranged on two opposite sides of the mahjong carrying table, the reversing wheels are positioned right below the first conveying wheels, and the conveying belt sequentially winds the reversing wheels and the second conveying wheels;

the mahjong tile feeding device is characterized in that a first mahjong tile blocking plate above the second conveying wheel is arranged on the mahjong tile feeding box, a guide roller opposite to the conveying channel is rotatably arranged on the first mahjong tile blocking plate, and the guide roller is higher than the surface of the conveying belt in the conveying channel and lower than the top surface of the mahjong tile on the conveying belt in the conveying channel.

The reversing wheel and the second conveying wheel are matched to enable the conveying belt running on the surface of the supporting table to descend to the surface of the card bearing table. However, when the feeding speed is too high, the continuously fed mahjong tiles may be crowded and abut against the first tile blocking plate, resulting in a wrong stacking of tiles. After the guide roller is arranged, when the mahjong tiles on the conveying channel fall, the head ends of the mahjong tiles are firstly contacted with the guide roller, the guide roller rotates under the pressure of the mahjong tiles, the head ends of the mahjong tiles are driven to tilt upwards, and the mahjong tiles are prevented from diving and are driven to fall onto the conveying belt on the surface of the tile bearing table.

In the multi-mechanism combined driving device of the roller coaster type full-automatic mahjong machine, the length of the conveying channel is less than or equal to one fourth of the total length of mahjong tiles, a second magnetic control sensor is arranged at a tile taking port of the conveying channel and used for detecting whether magnetic mahjong tiles stay at the tile taking port of the conveying channel;

In order to ensure that the mahjong pieces with the same quantity are conveyed by each mahjong piece taking and conveying mechanism, and avoid complex tile returning operation of the mahjong piece taking and conveying mechanism caused by overlong conveying channels, the length of the conveying channels is set to be less than or equal to one fourth of the total length of the mahjong pieces, and the maximum capacity of the conveying channels cannot exceed the quantity of the mahjong pieces of each party of the mahjong machine.

The invention divides the feeding action in the conveying channel into two stages, the mahjong tiles exceeding the length of the conveying channel are firstly fed into the stacking and pushing mechanism for stacking in the first stage, and after the first stage is finished, the action of the stacking and pushing mechanism is suspended (when the length of the conveying channel is equal to one fourth of the total length of the mahjong tiles, the stage is not needed); in the second stage, the mahjong pieces with the same length as the conveying channels are firstly sucked into the conveying channels, and as the second magnetic control sensor is arranged at the mahjong piece taking opening of the conveying channels, when the second magnetic control sensor detects that mahjong pieces stay at the mahjong piece taking opening of the conveying channels, the mahjong pieces are fully stored in the conveying channels, and only after all the conveying channels are fully stored, the mahjong piece stacking and pushing mechanism can be restarted. Because the conveying channel of the stored mahjong tiles can not accept the redundant mahjong tiles any more, tile returning operation is not needed.

Meanwhile, the stacking and pushing actions of mahjong tiles are divided into two stages (corresponding to the two stages of the tile feeding actions respectively), a third magnetic control sensor is arranged to monitor whether tile piers are stacked or not, in the first stage, a main control board pauses a large disc driving motor as long as stacking of one tile pier is completed, after a tile pushing head completes tile pushing actions and returns to a tile pushing initial position, the large disc driving motor is restarted until the first tile pier is stacked, and at the moment, the last tile pier temporarily reserved on a tile carrying table in the first tile pier is utilized to prop against a conveying channel, so that mahjong tiles are prevented from continuously falling onto the tile carrying table; and after the mahjong tiles are fully stored in the conveying channel, the stacking and pushing action of the second stage is implemented until all stacking and pushing are completed.

Besides controlling the start-stop of the conveyer belt by controlling the start frequency of the large-disc driving motor to realize the one-by-one stacking pushing, a card blocking part can be arranged on one side of the card pushing head facing the conveying channel, and the card blocking part always props against a card outlet of the conveying channel in the card pushing process; however, when the length of the conveying channel is equal to one fourth of the total length of the mahjong tiles, the first stage of the stacking pushing action does not exist, and at the moment, the tile blocking part is arranged to prop against the tile outlet of the conveying channel conveniently, and the tile pushing sliding block can be directly utilized to block the tile outlet of the conveying channel.

In the multi-mechanism combined driving device of the roller coaster type full-automatic mahjong machine, the rising and carrying mechanisms comprise rising and carrying plates, fixed ends of the rising and carrying plates are hinged with the base, and a second rocker arm for driving the rising and carrying plates to turn over is arranged below each rising and carrying plate;

the second unidirectional transmission mechanism comprises a transmission gear which is connected to the card taking conveying box through rotation and a second driven gear which is fixedly arranged on the second rocker arm, the second driven gear is in transmission connection with the first driven gear through the transmission gear, and a second unidirectional bearing is arranged between the transmission gear and the second horizontal shaft, between the second driven gear and the second mandrel or between the second mandrel and the shaft sleeve;

The bottom of the card lifting and carrying plate is provided with a lower fin plate, and the distance between the lower fin plate and the fixed end of the card lifting and carrying plate is smaller than the distance between the lower fin plate and the free end of the card lifting and carrying plate; the second rocker arm is abutted against the bottom surface of the lower fin plate, and the distance between the second rocker arm and the two end surfaces of the lower fin plate is larger than or equal to the action radius of the second rocker arm.

The additionally arranged lower fin plate is used as the extension of the second rocker arm, so that the card lifting and carrying plate can still turn over a larger angle on the premise of adopting the second rocker arm with a smaller action range, thereby improving the transmission efficiency. The lower fin plate is arranged closer to the fixed end of the card lifting and supporting plate, and the second rocker arm with a smaller action range is adopted to drive the card lifting and supporting plate to turn over by a larger angle. The distance between the second rocker and the two end faces of the lower fin plate is set to be equal to or larger than the action radius of the second rocker, so that the second rocker is always abutted against the bottom face of the lower fin plate no matter how the second rocker acts, the turnover of the card lifting and bearing plate is stable, and the card lifting and bearing plate cannot be rapidly lifted.

Compared with the prior art, the invention has the beneficial effects that:

the invention is good at using the natural advantage of the big shuffling tray, while adopting the big tray driving motor to drive the big shuffling tray to rotate, utilize the reversing transmission mechanism to transmit the rotation of the big shuffling tray to the driving wheel of the card taking and stacking mechanism positioned at each azimuth of the big shuffling tray, and further utilize the driving wheel of the card taking and stacking mechanism to transmit the rotation of the big shuffling tray to the card lifting and bearing mechanism, because the card taking and stacking operation of the card taking and stacking mechanism and the card lifting operation of the card lifting and bearing mechanism are not synchronously carried out, the transmission between the card taking and stacking mechanism and the card lifting and bearing mechanism is realized by adopting a second unidirectional transmission mechanism; similarly, the shuffling operation of the shuffling tray and the lifting of the central lifting mechanism are not completely synchronous, so that the transmission between the large-tray driving motor and the central lifting mechanism or between the shuffling tray and the central lifting mechanism is realized by adopting the first transmission mechanism. The invention adopts the first driving mechanism to drive the central lifting mechanism, the shuffling mechanism, all the card taking and stacking mechanisms and all the card lifting and bearing mechanisms, thereby greatly saving the manufacturing cost and the running cost of the mahjong machine.

In this embodiment, the first reversing gear set includes a first bevel gear 73 mounted on the output shaft of the large disc drive motor 111, and a second bevel gear 74 meshed with the first bevel gear 73 is mounted on one end of the first spindle 721 passing through the rocker arm base 71, and a first unidirectional bearing 77 is provided between the first bevel gear 73 and the output shaft of the large disc drive motor 111, between the second bevel gear 74 and the first rocker arm 72, or between the first spindle 721 and the rocker arm base 71.

The large-disc driving motor 111 performs the shuffling operation when driving the shuffling large disc 21 to rotate, but the shuffling operation is not synchronized with the lifting operation of the lifting lever 32 and the operation disc, so that the first one-way bearing 77 needs to be provided on the transmission path of the large-disc driving motor 111 and the lifting lever 32 to ensure one-way transmission and ensure that each mechanism maintains a relatively independent working state. The first one-way bearing 77 may be provided at any position between the first bevel gear 73 and the output shaft of the large disc drive motor 111, between the second bevel gear 74 and the first rocker arm 72, or between the first spindle 721 and the rocker arm base 71, or may be provided at a plurality of positions at the same time, as the case may be.

In the card-taking and conveying unit 4 of the embodiment, the magnetic card-feeding wheel 42 is a driving wheel, and the magnetic card-feeding wheel 42 is also driven by the large-disc driving motor 111 and is driven by the reversing driving mechanism 8.

As shown in fig. 8 and 9, and in combination with fig. 6 and 7, the card stacking unit 5 is located at the card outlet of the conveying channel 415, and the card taking conveying unit 4 and the card stacking unit 5 of this embodiment are organically combined, so that the structure is compact. The card stacking unit 5 includes a card table 51 formed by a top wall of the card taking carriage 411, and a lower chamber 414 extends below the card table 51; the height of the card bearing table 51 is lower than that of the conveying channel 415, reversing wheels 52 and second conveying wheels 53 are respectively arranged on two opposite sides of the card bearing table 51, wherein the reversing wheels 52 are positioned right below the first conveying wheels 43, and a first card baffle 54 positioned above the second conveying wheels 53 is fixedly arranged on the card taking conveying box 41; a conveyer belt 45 is sleeved among the magnetic card feeding wheel 42, the first conveyer wheel 43, the reversing wheel 52, the second conveyer wheel 53 and the tensioning wheel 44, and the conveyer belt 45 is horizontally arranged between the magnetic card feeding wheel 42 and the first conveyer wheel 43 and between the reversing wheel 52 and the second conveyer wheel 53 and respectively runs against the surfaces of the tray table 413 and the card bearing table 51. Meanwhile, a second card baffle 55 and a card pushing port are respectively arranged on two opposite sides of the card bearing table 51, and the conveying channel 415, the second card baffle 55 and the first card baffle 54 enclose a card stacking space.

The stacking space is narrow, the tile-holding table 51 is arranged at the lower part of the tile outlet of the conveying channel 415, and the conveying belt 45 is arranged on the surface, so that the mahjong tiles falling from the conveying channel 415 can be conveniently held, and the mahjong tiles can be conveniently stacked. Obviously, the height difference between the holding table 51 and the delivery path 415 should be equivalent to the thickness of one mahjong tile (for stacking two mahjong tiles) or to the thickness of two mahjong tiles (for stacking three mahjong tiles). The conveyer 45 slides from the surface of the tile-supporting table 51 to be beneficial to relieving the inertial impact between the mahjong tiles falling from the conveying channel 415 and the surface of the tile-supporting table 51, and avoiding tile placement.

However, when the height difference between the deck 51 and the delivery path 415 is large, the falling mahjong pieces may possibly turn; and when the feed speed is too high, the continuously fed mahjong tiles may become crowded and abut against the first tile stop 54. Therefore, in the embodiment, the guide roller 56 opposite to the conveying channel 415 is rotatably arranged on the first card baffle 54, and the height of the guide roller 56 is higher than the height of the surface of the conveying belt 45 in the conveying channel 415 and lower than the height of the top surface of the mahjong tiles on the conveying belt 45 in the conveying channel 415. When the mahjong tiles on the conveying channel 415 fall, the head ends of the mahjong tiles are firstly contacted with the guide-falling rollers 56, the guide-falling rollers 56 rotate under the pressure of the mahjong tiles to drive the head ends of the mahjong tiles to tilt upwards, so that the mahjong tiles are prevented from diving and simultaneously are driven to fall onto the conveying belt 45 on the surface of the tile bearing table 51.

As shown in fig. 6, and as can be seen in fig. 4 and 5, a card feeding mechanism 13 is provided at the card pushing port of each card stacking unit 5. The card feeding mechanism 13 comprises a card storing rail 131 which is positioned and installed on the integrated part 102, the card storing rail 131 is connected with a card pushing port, a chute 131a is arranged on the top surface of the side wall of the card storing rail 131, the chute 131a extends to the upper side of the second card baffle 55, and a card pushing head 132 is slidably installed in the chute 131 a. A second driving mechanism 12 for driving each card pushing head 132 to move along the card storing track 131 is arranged on the top surface of the integrated part 102.

The second driving mechanism 12 of the present embodiment includes a turntable 121 rotatably mounted on the top surface of the integrated part 102, the turntable 121 is driven by a turntable driving motor 122 to reciprocally rotate, and a transmission structure 125 for driving the card pushing head 132 to work is mounted on the bottom surface of the turntable 121.

The card pushing head 132 of the present embodiment includes a card pushing head body 132a, the card pushing head body 132a has a first sliding rod 132b slidably engaged with the sliding groove 131a and a card pushing slider 132c extending into the card storing track 131, and the card pushing slider 132c has a card blocking portion 132d facing one side of the conveying channel 415. The card pushing start point of the card pushing slider 132c is close to the second card blocking plate 55, and at the same time, the card pushing slider 132c has a repeated card pushing position (the card blocking part 132d does not leave the card stacking space during the card pushing process) for pushing the card piers on the card holding table 51 into the card storage rail 131 one by one while preventing the mahjong pieces from falling onto the card holding table 51 from the conveying channel 415, and a card feeding position for pushing all the card piers in the card storage rail 131 onto the card lifting card holding plate 61.

It should be noted that, the blocking portion 132d is not necessary in the present invention, and in the case where the conveyer 45 is continuously running (the stacking operation is not finished, and the large-disc driving motor 111 is continuously rotating), the blocking portion 132d is provided to prevent the returning of the pusher head 132 to the pusher start point due to the fact that the conveyer 45 continuously conveys the mahjong pieces into the stacking space when the pusher head 132 leaves the stacking space; of course, the rotation frequency of the large-disc driving motor 111 can also be controlled to prevent mahjong tiles from falling into the stacking space when the tile pushing head 132 leaves the stacking space, for example, when two mahjong tiles are conveyed into the stacking space, the large-disc driving motor 111 is stopped, and after the tile pushing head 132 pushes tiles and returns to the tile pushing initial point, the large-disc driving motor 111 is started again.

As shown in fig. 3 and 4, the output shaft of the turntable driving motor 122 of the present embodiment is mounted with a second driving gear 123 and a third driving gear 124 coaxially provided, and the turntable 121 includes a main disk 121a and a sub disk 121b coaxially provided with the main disk 121 a.

Wherein the main disc 121a is in a circular ring shape, the transmission structure 125 comprises a first annular folded edge 125a at the outer ring of the bottom surface of the main disc 121a, a second annular folded edge 125b at the inner ring of the bottom surface of the main disc 121a, and a second sliding rod 125c fixedly installed between the first annular folded edge 125a and the second annular folded edge 125 b; the second slide bars 125c are arranged on the four directions of the bottom surface of the main disc 121a and are in one-to-one correspondence with the card pushing heads 132, and the card pushing head body 132a is slidably arranged on the second slide bars 125c; at least two second slide bars 125c are provided on each side of the main disk 121a, and all the second slide bars 125c on the same side are disposed in parallel. The auxiliary disc 121b is disposed on the top surface of the main disc 121a and has a ring shape, and a plurality of stays 121c protruding from the top surface of the main disc 121a are formed on the main disc 121a, and all the stays 121c extend radially along the top surface of the main disc 121a and abut against the inner peripheral edge of the ring-shaped auxiliary disc 121b.

As can be seen from fig. 2, 3 and 4, in this embodiment, the periphery of the main disk 121a is provided with a card pushing tooth 121d, and the second driving gear 123 is meshed with the card pushing tooth 121d to drive the card pushing slider 132c to switch between a card pushing start position and a repeated card pushing position; the peripheral edge of the auxiliary disc 121b is provided with a card feeding tooth portion 121e, and the third driving gear 124 is meshed with the card feeding tooth portion 121e to drive the card pushing slider 132c to switch between the repeated card pushing position and the card feeding position, the peripheral edge of the main disc 121a is provided with a fourth magnetic control sensor 126 for monitoring the rotation angle of the main disc 121a, the fourth magnetic control sensor 126 is connected with a main control board, and the main control board is used for receiving the output signal of the fourth magnetic control sensor 126 and controlling the start, stop and steering of the turntable driving motor 122 according to the output signal.

Since the outer diameter of the main disc 121a is larger than that of the sub disc 121b, the outer diameter of the second driving gear 123 is smaller than that of the third driving gear 124; therefore, the rotation speed of the turntable 121 when the second driving gear 123 is meshed with the card pushing tooth portion 121d is slower than that of the turntable 121 when the third driving gear 124 is meshed with the card feeding tooth portion 121e, because the card pushing head 132 only pushes one card pier at a time when pushing cards, and if the card pushing speed is too fast, the card pier can easily tip over; when the card is sent, the card pushing head 132 pushes all the card piers together, the speed is slightly increased, the phenomenon that the card piers turn over can not occur, and the card sending speed can be increased.

As shown in fig. 3 and 4, the rotation mounting manner between the turntable 121 and the integrated part 102 is: at least two pressing strips 127 (four pressing strips 127 are uniformly distributed at four positions of the main disc 121a in the embodiment) are fixed on the top surface of the integral forming part 102 through threads, a hollow shaft 128 is rotatably arranged on bolts (at least two bolts are arranged on one pressing strip 127) for fixing the pressing strips 127 on the integral forming part 102, a second roller 129 (also can be a bearing) is arranged on the hollow shaft 128, an annular groove 125d for accommodating each second roller 129 is formed on the second annular flange 125b, and when the turntable driving motor 122 drives the turntable 121 to rotate, the second roller 129 rolls along the annular groove 125 d.

In order to ensure that the mahjong pieces of the same number are conveyed by each mahjong piece taking and stacking mechanism 14 and avoid repeated tile returning operation of each mahjong piece taking and stacking mechanism 14, the length of the conveying channel 415 is set to be less than or equal to one fourth of the total length of the mahjong pieces, and the maximum capacity of the conveying channel 415 cannot exceed the number of the mahjong pieces of each party of the mahjong machine; meanwhile, at the tile taking port of the conveying channel 415, a second magnetic control sensor 46 connected with a main control board is arranged on the tile taking conveying box cover 412, the second magnetic control sensor 46 is used for detecting whether magnetic mahjong tiles remain at the tile taking port of the conveying channel 415 or counting mahjong tiles entering the conveying channel 415, and the main control board is used for receiving an output signal of the second magnetic control sensor 46 and controlling the start and stop of the large-disc driving motor 111 according to the output signal. And, a third magnetic control sensor 57 connected with the main control board is also installed on the second tile blocking board 55, the height of the third magnetic control sensor 57 is equal to the height of the mahjong tiles stacked on the uppermost part of the conveying belt 45, and the third magnetic control sensor is used for detecting whether the mahjong tiles on the tile bearing table 51 are stacked, counting the number of the stacked mahjong tiles, and the main control board is used for receiving the output signal of the third magnetic control sensor 57 and controlling the turntable driving motor 122 (or the turntable driving motor 122 and the large-disc driving motor 111) according to the output signal, and on the premise that the tile blocking part 132d is not provided, the turntable driving motor 122 and the large-disc driving motor 111 are required to be controlled to start and stop simultaneously.

Taking the length of the conveying channel 415 as the length of six mahjong tiles and 136 total mahjong tiles as an example, when one third magnetic control sensor 57 detects that 14 mahjong tiles are stacked, the main control board pauses the turntable driving motor 122, and meanwhile the blocking part 132d of the tile pushing sliding block 132c is abutted against the tile outlet of the conveying channel 415 to prevent the mahjong tiles from falling to the tile bearing table 51; at this time, the large-disc driving motor 111 works normally, and the magnetic card feeding wheel 42 continuously takes cards until the conveying channel 415 is full of six mahjong pieces; as long as the other conveying channel 415 is not full, the big disc driving motor 111 continuously works, and the shuffling big disc 21 and the magnetic card feeding wheel 42 continuously rotate; if the mahjong tiles are adsorbed by the magnetic tile loading wheels at the positions of the conveying channels 415 where the mahjong tiles are fully stored, as the conveying belt 45 continuously runs, redundant mahjong tiles can fall into the large shuffling tray 21 again until the second magnetic control sensor 46 detects that all the mahjong tiles are fully stored in the conveying channels 415, at the moment, the main control board pauses the large tray driving motor 111, and starts the turntable driving motor 122 to engage the second driving gear 123 with the tile pushing tooth parts 121d at the moment, so that the rest six mahjong tiles are stacked and pushed. After all 17 piers are stacked and pushed into the card storing rail 131, the turntable driving motor 122 continues to operate, and at this time, the third driving gear 124 is meshed with the card feeding tooth 121e, so that all piers are pushed to the card feeding end of the card storing rail 131.

Each card lifting and bearing mechanism 6 comprises a card lifting and bearing plate 61, the fixed end of the card lifting and bearing plate 61 is hinged with the integrated part 102, the free end faces the card sending end of the card storage rail 131, and when the card lifting and bearing plate 61 is turned downwards, the free end can be connected with the card sending end of the card storage rail 131.

In this embodiment, the bottom surface of the card lifting and supporting plate 61 is provided with a lower fin plate 62 integrally arranged, the distance between the lower fin plate 62 and the fixed end of the card lifting and supporting plate 61 is smaller than the distance between the lower fin plate 62 and the free end of the card lifting and supporting plate 61, and a second rocker arm 63 for driving the card lifting and supporting plate 61 to turn over is arranged below each lower fin plate 62.
