The mahjong stacking space enclosed by the conveying channel and the first mahjong blocking plate is narrow, and the mahjong bearing platform is arranged at the lower part of the mahjong outlet of the conveying channel so as to be convenient for receiving mahjong falling from the conveying channel and stacking the mahjong. Obviously, the difference in height between the deck and the delivery path should be comparable to the thickness of one tile (for stacking two tiles) or two tiles (for stacking three tiles).

Moreover, the conveying belt runs in the conveying channel and runs on the surface of the mahjong tile bearing table, the conveying belt extends to the surface of the mahjong tile bearing table, so that the inertia impact between mahjong tiles falling from the conveying channel and the surface of the mahjong tile bearing table can be relieved, and the tiles can be prevented from being planted.

The reversing wheel and the second conveying wheel are matched to lower the conveying belt running on the surface of the pallet to the surface of the bearing platform. However, when the conveying speed is too fast, the continuously conveyed mahjong pieces may be crowded and abut against the first card blocking plate, and the card stacking error is caused. After the drop guide roller is arranged, when the mahjong tiles on the conveying channel fall, the head end of the mahjong tiles firstly contacts with the drop guide roller, the drop guide roller rotates under the pressure of the mahjong tiles to drive the head end of the mahjong tiles to upwarp, and the mahjong tiles are prevented from diving and simultaneously driven to fall onto the conveying belt on the surface of the tile bearing table.

In order to ensure that the mahjong tiles with the same quantity are conveyed by each mahjong tile taking and conveying mechanism and avoid the complicated mahjong tile returning operation of the mahjong tile taking and conveying mechanism caused by the overlong conveying channel, the length of the conveying channel is set to be less than or equal to one fourth of the total length of the mahjong tiles, and the maximum capacity of the conveying channel is ensured not to exceed the quantity of the mahjong tiles of each side of the mahjong machine.

The mahjong tile feeding action in the conveying channel is divided into two stages to be carried out, mahjong tiles exceeding the length of the conveying channel are firstly conveyed into the tile stacking and pushing mechanism to be stacked in the first stage, and the action of the tile stacking and pushing mechanism is suspended after the first stage is finished (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, all mahjong tiles with the length equivalent to that of the conveying channel are sucked into the conveying channel, and the second magnetic control sensor is arranged at the tile taking port of the conveying channel, so that when the second magnetic control sensor detects that mahjong tiles stop at the tile taking port of the conveying channel, the mahjong tiles are full in the conveying channel, and only after all the conveying channels are full of the mahjong tiles, the stacking and pushing mechanism is restarted. Because the conveying channel filled with mahjong can not receive the surplus mahjong, the mahjong tile returning operation is not needed.

Meanwhile, the stacking and pushing action of mahjong tiles is divided into two stages (corresponding to the two stages of the tile sending action respectively), a third magnetic control sensor is arranged to monitor whether the tile piers are stacked, in the first stage, as long as the stacking of one tile pier is completed, the main control board suspends the large-disc driving motor, after the tile pushing head completes the tile pushing action and returns to the tile pushing starting point, the large-disc driving motor is restarted until the first tile pier is stacked, and at the moment, the last tile pier temporarily left on the tile bearing table in the first tile pier is utilized to abut against the conveying channel, so that the mahjong tiles are prevented from continuously falling onto the tile bearing table; after the conveying channel is filled with mahjong pieces, the second stage of stacking and pushing action is carried out until all stacking and pushing actions are completed.

The starting and stopping of the conveying belt are controlled by controlling the starting frequency of the large disc driving motor to realize stacking and pushing one by one, and a card blocking part can be arranged on one side of the card pushing head facing the conveying channel and always abuts 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 and pushing action does not exist, the tile blocking part is arranged to abut against the tile outlet of the conveying channel conveniently, and the tile outlet of the conveying channel can be blocked by directly utilizing the tile pushing sliding block.

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

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

the bottom of the tile lifting and supporting plate is provided with a lower fin plate, and the distance between the lower fin plate and the fixed end of the tile lifting and supporting plate is smaller than the distance between the lower fin plate and the free end of the tile lifting and supporting 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 added lower fin plate is used as the extension of the second rocker arm, so that the mahjong lifting and supporting plate can still turn over a larger angle on the premise of adopting the second rocker arm with a smaller action range, and the transmission efficiency is improved. The lower fin plate is arranged closer to the fixed end of the tile lifting and supporting plate, and the second rocker arm with a smaller action range is also used for driving the tile lifting and supporting plate to turn over by a larger angle. And set up the distance between second rocker and the fin both ends face down into the action radius of equal more than or equal to second rocker, be in order to ensure no matter how the second rocker moves, the second rocker supports all the time and leans on fin bottom surface down for the upset of rising tablet board of holding is more steady, can not rise the rapid fall suddenly.

Compared with the prior art, the beneficial effect of this application is embodied in:

the application is good at the natural advantages of the large shuffling disc, the reversing transmission mechanism is utilized to transmit the rotation of the large shuffling disc to the driving wheels of the card taking and stacking mechanism positioned on each direction of the large shuffling disc while the large shuffling disc is driven to rotate by the large disc driving motor, and the driving wheels of the card taking and stacking mechanism are further utilized to transmit the rotation of the large shuffling disc to the card lifting and holding mechanism; similarly, the shuffling operation of the large shuffling disk and the lifting of the central lifting mechanism are not completely synchronized, so that the transmission between the large disk driving motor and the central lifting mechanism or between the large shuffling disk and the central lifting mechanism is also realized by adopting the first transmission mechanism. The mahjong machine adopts the first driving mechanism to drive the central lifting mechanism, the shuffling mechanism, all the mahjong taking and stacking mechanisms and all the mahjong lifting and holding mechanisms, so that the manufacturing cost and the running cost of the mahjong machine are greatly saved.

As shown in fig. 8 and 9 and seen in combination with fig. 6 and 7, the card folding unit 5 is located at the card outlet of the conveying channel 415, and the card taking and conveying unit 4 and the card folding unit 5 of the present embodiment are organically combined, so that the structure is compact. The card folding unit 5 comprises a card bearing platform 51 formed by the top wall of the card taking conveying box frame 411, and the lower cavity 414 extends to the lower part of the card bearing platform 51; the height of the card bearing table 51 is lower than that of the conveying channel 415, the two opposite sides of the card bearing table 51 are respectively provided with a reversing wheel 52 and a second conveying wheel 53, wherein the reversing wheel 52 is positioned right below the first conveying wheel 43, and the card taking and conveying box 41 is also fixedly provided with a first card blocking plate 54 positioned above the second conveying wheel 53; the conveyer belt 45 is installed between the magnetic card-feeding wheel 42, the first conveyer wheel 43, the reverse wheel 52, the second conveyer wheel 53 and the tension 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 reverse wheel 52 and the second conveyer wheel 53 and runs along the surfaces of the support 413 and the card-receiving platform 51. Meanwhile, a second card baffle 55 and a card pushing opening are respectively arranged on two opposite sides of the card bearing platform 51, and a card stacking space is enclosed by the conveying channel 415, the second card baffle 55 and the first card baffle 54.

The space for stacking the mahjong pieces is narrow, the mahjong piece holding platform 51 is arranged at the lower part of the mahjong piece outlet of the conveying channel 415, the conveying belt 45 is arranged on the surface of the mahjong piece holding platform, so that the mahjong pieces falling from the conveying channel 415 can be received conveniently, and meanwhile, the mahjong pieces can be stacked conveniently. Obviously, the difference in height between the deck 51 and the delivery path 415 should be comparable to the thickness of one tile (for stacking two tiles) or two tiles (for stacking three tiles). The sliding of the conveyer belt 45 from the surface of the tile bearing table 51 is beneficial to relieving the inertia impact between the mahjong falling from the conveying channel 415 and the surface of the tile bearing table 51, and the tile falling is avoided.

However, when the height difference between the support table 51 and the conveying passage 415 is large, the fallen mahjong pieces may be turned; also, when the speed of delivery is too fast, the continuously delivered tiles may jam against the first card stop 54. Therefore, the guide roller 56 is rotatably mounted on the first card retainer 54 opposite to the conveying path 415, and the guide roller 56 is higher than the surface of the first conveyor belt 45 in the conveying path 415 and lower than the top surface of the mahjong tiles on the first conveyor belt 45 in the conveying path 415. When the mahjong tiles on the conveying channel 415 fall, the head end of the mahjong tiles firstly contacts with the guiding and falling roller 56, the guiding and falling roller 56 rotates under the pressure of the mahjong tiles to drive the head end of the mahjong tiles to be upwarped, and the mahjong tiles are driven to fall onto the conveying belt 45 on the surface of the tile bearing platform 51 while avoiding the mahjong tiles from diving downwards.

As shown in fig. 6, and as can be seen from fig. 4 and 5, a card feeding mechanism 13 is provided at the card pushing port of each card stacking unit 5. The card sending mechanism 13 includes a card storing track 131 positioned and installed on the integrated part 102, the card storing track 131 is connected with the card pushing port, a sliding groove 131a is arranged on the top surface of the side wall of the card storing track 131, the sliding groove 131a extends to the upper side of the second card retaining plate 55, and a card pushing head 132 is installed in the sliding groove 131a in a sliding manner.

The start point of pushing the tile of the tile pushing slider 132c is close to the second tile stopping plate 55, and the tile pushing slider 132c has a repeated tile pushing position for pushing the tiles on the tile bearing platform 51 one by one into the tile storing track 131 and preventing the mahjong tiles from falling from the conveying channel 415 onto the tile bearing platform 51 (the tile stopping portion 132d does not leave the tile stacking space during the tile pushing process), and a tile sending position for pushing all the tiles in the tile storing track 131 onto the tile lifting and bearing plate 61.

It should be noted that the card blocking portion 132d is not necessary in the present application, and in the case where the conveying belt 45 is continuously running (the stacking operation is not completed, and the large-disc driving motor 111 is continuously rotating), the card blocking portion 132d is provided to prevent the conveying belt 45 from continuously conveying mahjong tiles into the stacking space when the card pushing head 132 leaves the stacking space, so that the card pushing head 132 cannot return to the card pushing start point; of course, the rotation frequency of the big-disc driving motor 111 can be controlled to prevent mahjong tiles from falling into the tile stacking space when the tile pushing head 132 leaves the tile stacking space, for example, when two mahjong tiles are conveyed into the tile stacking space, the big-disc driving motor 111 is paused, and after the tile pushing head 132 finishes pushing the tiles and returns to the tile pushing start point, the big-disc driving motor 111 is started again.

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

Since the outer diameter of the main disc 121a is larger than that of the sub disc 121b and the outer diameter of the second driving gear 123 is smaller than that of the third driving gear 124; therefore, the rotating speed of the turntable 121 when the second driving gear 123 is meshed with the card pushing tooth part 121d is slower than that of the turntable 121 when the third driving gear 124 is meshed with the card sending tooth part 121e, because the card pushing head 132 pushes only one card pier at a time when the cards are pushed, and the card piers are prone to tilting forwards and overturning if the card pushing speed is too fast; when the cards are sent, the card pushing head 132 pushes all the card piers together, so that the card piers are not turned over, and the card sending speed can be increased.

As shown in fig. 3 and 4, the rotational mounting manner between the turntable 121 and the integrally formed member 102 is as follows: at least two pressing strips 127 (four pressing strips 127 are arranged in the embodiment and evenly distributed at four positions of the main disc 121 a) are fixed on the top surface of the integrally-formed part 102 through threads on the inner ring of the main disc 121a, hollow shafts 128 are rotatably mounted on bolts (at least two bolts are arranged on one pressing strip 127) used for fixing the pressing strips 127 on the integrally-formed part 102, second rollers 129 (which can also be bearings) are arranged on the hollow shafts 128, annular grooves 125d used for accommodating the second rollers 129 are formed in the second annular folded edge 121b, and when the turntable 121 is driven by the turntable driving motor 122 to rotate, the second rollers 129 roll along the annular grooves 125 d.

In order to ensure that each tile taking and stacking mechanism 14 delivers the same number of tiles and avoid the repeated tile returning operation of each tile taking and stacking mechanism 14, the length of the delivery channel 415 is set to be less than or equal to one fourth of the total length of the tiles, so as to ensure that the maximum capacity of the delivery channel 415 cannot exceed the number of tiles of each side of the mahjong machine; meanwhile, at the tile taking port of the conveying channel 415, the second magnetic control sensor 46 connected with the 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 are stopped at the tile taking port of the conveying channel 415 or counting the 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-disk drive motor 111 according to the output signal. And, the second card stopping board 55 is further provided with a third magnetic control sensor 57 connected to the main control board, the third magnetic control sensor 57 is located at a height equivalent to that of the top mahjong tile stacked on the conveying belt 45, and is configured to detect whether the mahjong tile on the tile supporting platform 51 is stacked and count the number of the stacked tiles, and the main control board is configured to receive an output signal of the third magnetic control sensor 57 and control the start and stop of the turntable driving motor 122 (or the turntable driving motor 122 and the large-disk driving motor 111, and on the premise that the card stopping portion 132d is not provided, the turntable driving motor 122 and the large-disk driving motor 111 need to be controlled simultaneously according to the output signal.

Taking the length of the conveying channel 415 as the length of six mahjong tiles and 136 mahjong tiles as an example, when the third magnetic control sensor 57 of one party detects that 14 mahjong tiles are stacked, the main control board suspends the turntable driving motor 122, and meanwhile, the tile blocking part 132d of the tile pushing slider 132c abuts against the tile outlet of the conveying channel 415, so as to prevent the mahjong tiles from falling to the tile bearing table 51; at this time, the large disk drive motor 111 works normally, and the magnetic mahjong tile feeding wheel 42 continuously takes mahjong tiles until the conveying channel 415 is full of six mahjong tiles; as long as the other transport path 415 is not full, the large disk drive motor 111 will continue to operate, and the shuffling large disk 21 and the magnetic card-feeding wheel 42 will continue to rotate; if the mahjong tiles are adsorbed by the magnetic mahjong tile feeding wheel at the position of the conveying channel 415 full of the mahjong tiles, the redundant mahjong tiles can fall into the tile shuffling large disk 21 again due to the continuous operation of the conveying belt 45 until the second magnetic control sensor 46 detects that all the conveying channels 415 are full of the mahjong tiles, at the moment, the main control board suspends the large disk driving motor 111, the rotary disk driving motor 122 is started, at the moment, the second driving gear 123 is meshed with the tile pushing tooth part 121d, and the remaining six mahjong tiles are overlapped and pushed.
