The first embodiment is as follows:

the utility model provides a fold tablet mechanism, as shown in fig. 2 to 6, including folding tablet motor 1, fold tablet wheel 2, hold in the palm tablet board 3 and pendulum rod 4, fold tablet wheel 2 by folding the drive of tablet motor 1, hold in the palm between the terminal platform 61 of tablet board 5 that the tablet board 3 is located the mahjong machine and send the tablet rail 6, hold in the palm the tablet board 3 and articulate in holding in the tablet board 5, hold in the palm tablet board 3 have with hold in the first position of tablet board 5 parallel and level and accept the second position of the general tablet M2 of second piece anesthesia, the second position is less than the first position, pendulum rod 4 articulates in support 7, pendulum rod 4 and hold in the palm tablet board 3 swing joint, fold and be equipped with cam 21 on the tablet wheel 2, pendulum rod 4 supports in cam 21's working face, cam 21 follows to fold the rotation of tablet wheel 2 and makes the pendulum rod 4 swing, pendulum rod 4 drives and holds in the palm tablet board 3 and moves to the first position from the second position, hold in the tablet board 3 and move to the second position from.

The utility model discloses well support tablet board 3 articulates in holding tablet board 5 or support 7, utilize the direction limiting action in articulated structure itself area, let support tablet board 3 can swing on a stable perpendicular, realize the position change of two co-altitude, consequently no longer need set up corresponding guide structure, because cam 21 and support tablet board 3 between direct through 4 transmission power of pendulum rod, and pendulum rod 4 only need drive support tablet board 3 and overcome gravity and move to the primary importance from the second place, support tablet board 3 moves to the second place from the primary importance through gravity, consequently need not consider to set up the structure that drives support tablet board 3 reciprocating motion, thereby can simplify the structure of transmission power greatly, the part quantity significantly reduces, assembly efficiency can improve naturally, can effectively reduce manufacturing cost.

The fact that the card supporting plate 3 is flush with the card supporting plate 5 means that the top surface of the card supporting plate 3 is flush with the card supporting surface 51 (generally, the top surface) of the card supporting plate 5. In the embodiment, because the card supporting plate 3 and the card bearing plate 5 share the card bearing function, the card supporting plate 3 is hinged to the card bearing plate 5, and when the card supporting plate 3 is at the first position by taking the card bearing plate 5 as a reference, the top surface of the card supporting plate 3 and the card bearing plate 5 of the card bearing plate 5 can be kept flush. It will be appreciated that it is also possible for the card support plate 3 to be hinged to the support 7.

Because the card supporting plate 3 only needs to move up and down, the cam 21 is vertically arranged and drives the swing rod 4 to swing up and down through rotating motion, which is the simplest scheme, and the card stacking wheel 2 can be selected to be vertically arranged to be better correspondingly.

In brief, in the present invention, the cam 21 rotates one circle to realize the overlapping of two mahjong tiles and push the two mahjong tiles onto the tile support plate 5, the first mahjong tile M1 is the mahjong tile located at the lower position in the two stacked mahjong tiles, the second mahjong tile M2 is the mahjong tile located at the upper position in the two stacked mahjong tiles, and the two stacked mahjong tiles can be seen from fig. 20 and 21.

In the prior art, in order to push the two stacked mahjong tiles to the tile bearing plate 5, a tile pushing head is generally installed and moves horizontally to push the stacked mahjong tiles, for example, two invention patent applications mentioned in the background art can be understood, the utility model discloses also can adopt the structure of pushing the tile head to push the two stacked mahjong tiles to the tile bearing plate 5. Since the structure of the tile pushing head further complicates the structure of the tile stacking mechanism, in this embodiment, in order to reduce the structure required for pushing tiles, the stacked tiles are pushed onto the tile bearing plate 5 by using the subsequently fed tiles, and for this purpose, the end platform 61 of the tile feeding rail 6 is designed to be higher than the tile bearing surface 51 of the tile bearing plate 5, so that the tiles on the end platform 61 of the tile feeding rail 6 move forward to push the two tiles stacked on the tile bearing plate 3 onto the tile bearing plate 5, as can be seen from the dotted lines in fig. 8 and 12, where the forward movement refers to the moving direction of the tiles, which can be understood as the direction from left to right in fig. 16 and 18, and the process of pushing the stacked tiles by the first subsequently fed tile M1 can refer to fig. 16 to 21.

In the stacking process, when the holding plate 3 is at the second position, the first mahjong tile M1 on the holding plate 3 is obliquely placed, the second mahjong tile M2 has a certain height difference with the first mahjong tile M1 on the holding plate 3, if the second mahjong tile M2 is pushed directly onto the first mahjong tile M1, the second mahjong tile M2 falls onto the first mahjong tile M1, so that the noise of mahjong tile collision is generated, in order to eliminate the noise, the holding plate 3 can be designed to have a third position, the third position is located between the first position and the second position, the holding plate 3 moves to the third position when receiving the second mahjong tile M2, so that the second mahjong tile M2 moves to the first mahjong tile M1 along the top surface of the first mahjong tile M1, when the gravity center of the second mahjong tile M2 moves to the position above the second mahjong tile M1, and the gravity center of the second mahjong tile M3552 is stably supported by the first mahjong tile 1, to achieve this action, the working surface of the cam 21 may be designed to include a first drive surface 211 that moves the card support plate 3 from the second position to the third position and back to the second position, as seen in figure 7, in coordination with the movement of the second mahjong tile M2 back to the second position. In the process that the center of gravity of the second mahjong tile M2 moves and is changed from the position above the tail end platform of the tile feeding rail to the position above the first mahjong tile M1, the first mahjong tile M1 is used for carrying the second mahjong tile M2, the second mahjong tile M2 moves along the top surface of the first mahjong tile M1 to be stacked, the situation that the second mahjong tile M2 falls off cannot occur, the noise caused by collision of the mahjong tiles cannot be generated naturally, and the stability and reliability of the two mahjong tiles in the process of stacking the mahjong tiles can be improved. The return of the card support plate 3 from the third position to the second position is to ensure that the second tile M2 is pushed instead of the first tile M1.

In order to maintain the card support plate 3 in the first position for a period of time, the working surface of the cam 21 may be designed to include a first arcuate surface 212 that maintains the card support plate 3 in the first position. To move the card support plate 3 from the first position to the second position, the working surface of the cam 21 may include a second driving surface 213 for swinging the card support plate 3 from the first position to the second position. For the same reason, in order to keep the card support plate 3 at the second position for a while, the working surface of the cam 21 may be designed to include a second circular arc surface for keeping the card support plate 3 at the second position. In order to allow the card support plate 3 to swing from the second position to the first position, the working surface of the cam 21 may be designed to include a third driving surface 215. The second arcuate surface includes a longer segment 2141 and a shorter segment 2142, the longer segment 2141 being between the first drive surface 211 and the second drive surface 213, and the shorter segment 2142 being between the first drive surface 211 and the third drive surface 215, because it is necessary to ensure that the second mahjong M2 is pushed onto the first mahjong M1 to align the two mahjong tiles, and the card supporting plate 3 needs to remain in the second position for a period of time after returning from the third position to the second position.

The oscillating bar 4 can directly slide on the working surface of the cam 21, and the first roller 41 which is in contact with the working surface of the cam 21 is arranged on the oscillating bar 4 so that the oscillating bar 4 can move more smoothly relative to the working surface of the cam 21 and the friction resistance is reduced.

The swing rod 4 only needs to drive the card supporting plate 3 to swing against gravity, so that the swing connection between the swing rod 4 and the card supporting plate 3 can be realized in a simplest mode, the swing rod 4 and the card supporting plate 3 are in physical contact, specifically, the swing rod 4 extends to the lower part of the card supporting plate 3 to support the card supporting plate 3, and in order to reduce the friction resistance between the swing rod 4 and the card supporting plate 3, a second roller 42 in contact with the card supporting plate 3 can be arranged on the swing rod 4.

In this embodiment, the mahjong receiving surfaces 51 of the mahjong supporting plates 3 and 5 and the tail end platform 61 of the mahjong conveying rail 6 are in the same straight line direction, meanwhile, because the space in the mahjong machine is limited, the mahjong conveying direction of the mahjong conveying rail 6 is perpendicular to the movement direction of the mahjong during stacking, and the mahjong can continue to move after being reversed after moving to the tail end platform 61 of the mahjong conveying rail 6, so that power needs to be additionally provided to push the mahjong on the tail end platform 61 of the mahjong conveying rail 6, and the mahjong stacking is realized through the mahjong stacking wheel 2 in this embodiment. Specifically, the side of the mahjong stacking wheel 2 is provided with a transversely extending mahjong pushing rod 22, mahjong tiles on a tail end platform 61 of the mahjong feeding rail 6 are located on a rotating track of the mahjong pushing rod 22, the mahjong stacking wheel 2 is in transmission connection with an output shaft of the mahjong stacking motor 1, in the embodiment, a synchronous belt is adopted to realize transmission connection of the mahjong stacking wheel 2 and the mahjong stacking motor 1, the mahjong stacking wheel 2 is set to be a synchronous wheel, and an output shaft of the mahjong stacking motor 1 is also provided with a driving synchronous wheel 11. In the embodiment, the mahjong stacking wheel 2 and the cam 21 rotate for a circle to just push two mahjong pieces to realize one mahjong stacking operation, so that 2 mahjong pieces are arranged on the mahjong stacking wheel 2 and are uniformly distributed on the mahjong stacking wheel 22. In terms of generality, the cam 21 can rotate by an angle A to realize one-time card stacking work, and the number of the card pushing rods 22 is 720/A. For example, when the cam 21 rotates 240 degrees to realize one-time mahjong tile stacking operation, the number of the mahjong tile pushing rods 22 is 3, when the cam 21 rotates 180 degrees to realize one-time mahjong tile stacking operation, the number of the mahjong tile pushing rods 22 is 4, when the cam 21 rotates 120 degrees to realize one-time mahjong tile stacking operation, the number of the mahjong tile pushing rods 22 is 6. The smaller a, the larger the size of the cam 21, so it is generally preferable to adopt the solution of the present embodiment, which is advantageous for the miniaturization of the structure of the deck-folding mechanism. In order to avoid the situation that the card pushing rod 22 and the swing rod 4 are mutually interfered, the cam 21 can be designed to be positioned at the other side of the card stacking wheel 2. If the space allows, a curved track can be arranged at the tail end of the tile conveying rail 6 for the movement of the mahjong tiles, and the mahjong tiles can be conveyed on the tile conveying rail 6 to provide power for pushing the mahjong tile stack. In addition, if the card pushing lever 22 and the cam 21 are separately provided, for example, if the card pushing lever 22 is provided on a card pushing wheel, and the rotation speed ratio of the card pushing wheel to the card stacking wheel 2 is 2 to 1, only one card pushing lever 22 may be provided.

The tile stacking motor 1 can be selectively fixed on the bracket 7 and can also be arranged on the frame of the mahjong machine.

The sequence of stacking the tiles will be described in detail with reference to fig. 8 to 21.
