In the process of pushing the mahjong pieces by the mahjong pieces pushing head, if the mahjong pieces are continuously conveyed by the conveying belt, the mahjong pieces fall onto the mahjong carrying table when the mahjong pieces pushing head leaves the mahjong piece stacking space, and finally the mahjong pieces pushing head is difficult to return to the mahjong piece pushing initial position, and mahjong piece stacking and pushing errors occur. In order to solve this problem, the main control board of this application can also control the start and stop of first actuating mechanism according to the output signal of third magnetic control sensor, and the main control board just starts first actuating mechanism after waiting to push away the tablet head and push away the tablet and end and return to push away the tablet initiation site promptly to pause first actuating mechanism in the event that the third magnetic control sensor detects that the tablet mound superposes to accomplish promptly, and the conveyer belt just continues to carry mahjong pieces this moment.

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.

The card pusher 58 of this embodiment includes a card pusher body 581, the card pusher body 581 has a first slide rod 582 slidably engaged with the slide groove 571 and a card pusher block 583 extending into the card storage rail 57, and the card pusher block 583 has a card blocking portion 584 on a side facing the conveying path 415. The start point of the tile pushing block 583 is close to the second tile blocking plate 55, and at the same time, the tile pushing block 583 has a repeated tile pushing position (the tile blocking part 584 does not leave the tile stacking space during tile pushing) for pushing the tile piers on the tile holding table 51 into the tile storage rail 57 one by one while preventing the tile from falling onto the tile holding table 51 from the conveying channel 415, and a tile feeding position for pushing all the tile piers in the tile storage rail 57 onto the tile lifting tile holding plate.

It should be noted that, the blocking portion 584 is not necessary in the present application, and in the case where the conveyer 45 is continuously running (the stacking operation is not finished, and the large-disc drive motor 111 is continuously rotated), the blocking portion 584 is provided to prevent the conveyer 45 from continuously conveying the mahjong pieces into the stacking space when the pushing head 58 leaves the stacking space, so that the pushing head 58 cannot return to the pushing start position; 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 58 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 58 finishes pushing tiles and returns to the tile pushing start point, the large-disc driving motor 111 is started again.

As shown in fig. 4 and 5, 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.

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. 3, 4 and 5, 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 583 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 583 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 58 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; the card pusher 58 pushes all the card piers together when feeding cards, and the speed is slightly increased, so that the phenomenon that the card piers turn over can not occur, and the card feeding speed can be increased.

As shown in fig. 4 and 5, 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 with the same quantity are conveyed by each mahjong piece taking and conveying mechanism 4 and avoid that each mahjong piece taking and conveying mechanism 4 carries out repeated tile returning operation, 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 quantity 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 59 connected with the main control board is also installed on the second card baffle 55, the height of the third magnetic control sensor 59 is equal to the height of the mahjong tiles stacked on the uppermost part of the conveyer 45, and the third magnetic control sensor is used for detecting whether the mahjong tiles on the card bearing table 51 are stacked, counting the number of the stacked mahjong piers, and the main control board is used for receiving the output signal of the third magnetic control sensor 59 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 card baffle 584 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 59 detects that 14 mahjong tiles are stacked, the main control board pauses the turntable driving motor 122, and meanwhile the blocking part 584 of the tile pushing slider 583 abuts 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 absorbed by the magnetic tile feeding wheels 42 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 all the conveying channels 415, at the moment, the main control board pauses the large tray driving motor 111, the turntable driving motor 122 is started, at the moment, the second driving gear 123 is meshed with the tile pushing tooth parts 121d, and the rest six mahjong tiles are stacked and pushed. After all 17 piers are stacked and pushed into the card storing rail 57, the turntable driving motor 122 continues to operate, and at this time, the third driving gear 124 is meshed with the card feeding tooth portion 121e, so that all the piers are pushed to the card lifting and carrying mechanism 7 located in the card storing rail 57.

The working principle of the stacking and pushing card mechanism 5 of the mahjong machine is as follows:

when shuffling is needed, the large-disc driving motor 61 is started and rotates positively to drive the shuffling large disc 21 and the fluted disc 81 to rotate, the rotation of the fluted disc 81 is transmitted to the magnetic card feeding wheel 42 through the first reversing transmission gear 84 and the second reversing transmission gear 85, and mahjong tiles are sucked and brought into the conveying channel 415 in the rotating process of the magnetic card feeding wheel 42; at this time, the blocking portion 584 of the tile pushing head 58 abuts against the tile outlet of the conveying channel 415, when the conveying channel 415 is full of tiles, the turntable driving motor 122 is started, the tile pushing head 58 moves to the tile pushing starting position, the tiles fall onto the tile bearing table 51 from the tile outlet of the conveying channel 415 under the conveying of the conveying belt 45, the tiles can smoothly fall onto the tile bearing table 51 under the action of the conveying belt 45 and the guide roller 56 on the surface of the tile bearing table 51, and are stacked, and each time stacking of one tile pier is completed, the tile pushing head 58 moves to the repeated tile pushing position from the tile pushing starting position, and the tile piers are pushed into the tile storage track 57 one by one; when the third magnetic control sensor 59 detects that the first block of tiles is already stacked (because of stacking tiles simultaneously, each side is stacked substantially simultaneously to complete the first block of tiles), the main control board pauses the turntable driving motor 122, and simultaneously the blocking portion 584 of the tile pushing slider 583 abuts 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 61 works normally, and the magnetic card feeding wheel 42 continuously takes cards until the conveying channel 415 is full of mahjong tiles; as long as the other conveying channel 415 is not full, the big disc driving motor 61 continuously works, and the shuffling big disc 21 and the magnetic card feeding wheel 42 continuously rotate; if the mahjong pieces are absorbed by the magnetic tile feeding wheels 42 at the positions of the conveying channels 415 where the mahjong pieces are fully stored, as the conveying belt 45 continuously runs, redundant mahjong pieces can fall into the large shuffling tray 21 again until the second magnetic control sensor 46 detects that all the mahjong pieces are fully stored in the conveying channels 415, at the moment, the main control board pauses the large tray driving motor 61, starts the turntable driving motor 122, the second driving gear 123 is meshed with the tile pushing tooth parts 121d, and the rest six mahjong pieces are stacked and pushed until all 17 tile piers are stacked and pushed into the tile storage track 57.

Under the condition that no blocking part 584 is arranged, when mahjong tiles are conveyed in the conveying channel 415, whenever the third magnetic control sensor 59 detects that one tile pier is overlapped in the tile overlapping space, the main control board pauses the large-disc driving motor 111, when one tile pier is overlapped in the four tile overlapping spaces, the main control board starts the turntable driving motor 122, and the tile pushing head 58 pushes the four tile piers into the tile storage track 57 at the same time until the first tile pier is overlapped (the third magnetic control sensor 59 counts the tile piers); the last tile pier of the first batch of tile piers is temporarily left in the tile stacking space and used for blocking the tile outlet of the conveying channel 415, at the moment, the large disc driving motor 111 continuously rotates, and the conveying belt 45 continuously runs until the conveying channel 415 is full of mahjong tiles; after all the conveying channels 415 are full of mahjong tiles (monitored by the second magnetic control sensor 46), the main control board starts the turntable driving motor 122 again, and at the moment, the third driving gear 124 is meshed with the tile feeding tooth part 121e to drive the tile pushing head 58 to push the second batch of stacked tile piers into the tile storage track 131, and wait for next tile lifting.

The working principle is suitable for the situation that the length of the conveying channel 415 is smaller than one fourth of the total length of the mahjong tiles, and for the situation that the length of the conveying channel 415 is equal to one fourth of the total length of the mahjong tiles, the mahjong tiles are required to be stacked after all the conveying channels 415 are fully stored in advance, so that the tile outlet of the conveying channel 415 is blocked by the tile pushing slide block 583 or the tile blocking portion 584 in the tile fetching and conveying process of the tile fetching and conveying mechanism 4; after each conveying channel 415 is full of mahjong tiles, the main control board starts the turntable driving motor 122, and the mahjong tiles are stacked in the same tile stacking mode.

When a card is required to be lifted, the turntable driving motor 122 is started, the third driving gear 124 is meshed with the card feeding tooth part 121e, the card pushing head 58 pushes the mahjong cards in the card storage rail 57 to the direction of the card lifting and carrying plate, at the moment, the large-disc driving motor 111 is reversed, the reversed shuffling large disc 21 and the fluted disc 81 are transmitted to the magnetic card feeding wheel 42 through the first reversing transmission gear 84 and the second reversing transmission gear 85, so that the magnetic card feeding wheel 42 reversely rotates along with the first driven gear 82, and the second rocker reversely rotates along with the second driven gear 91, and the free end of the card lifting and carrying plate is lowered; after the mahjong tiles are pushed onto the mahjong tile lifting and bearing plate by the mahjong tile feeding mechanism, the second rocker arm continues to rotate to drive the free ends of the mahjong tile lifting and bearing plate to lift, and the mahjong tiles are fed onto the panel.
