Of course, an integrated layout manner, such as a manner that the conveyor belt and the front and rear rollers are provided with magnetic attraction points (magnets), which can be thought of and implemented by a person skilled in the art based on the present scheme, belongs to the scope of the present scheme according to the general knowledge, and is not described herein.
The invention also provides a card picking and stacking mechanism for the automatic mahjong machine, as shown in figures 1-4, the mechanism comprises a card stacking groove 6, a card picking and conveying mechanism 2 which is composed of a front roller 8, a rear roller 7, a driving unit 9 and a conveying belt 3 wound around the rollers, wherein the card picking and conveying mechanism 2 is also provided with a magnetic attraction point 1 capable of adsorbing magnetic mahjong pieces 5; the card stacking groove 6 is arranged below the rear-end roller 7, and the distance between the bottom of the card stacking groove 6 and the nearest part of the conveyor belt 3 positioned on the rear-end roller 7 is larger than the accumulated height of the mahjong pieces 5 to be stacked.
In a preferred use scheme of the specific automatic mahjong machine, after the mahjong pieces 5 falling into the stacking groove 6 are stacked to a specified number (generally, two pieces are stacked), the stacked mahjong pieces 5 can be pushed out of the stacking groove 6 through the tile pushing mechanism 10, and then the next tile picking and stacking operation is continued.
As shown in fig. 1-3, as one of the preferred embodiments, the magnetic attraction point 1 is provided on a front roller 8 and a rear roller 7, wherein the front roller 8 is provided with at least one magnetic attraction point 1 and the rear roller 7 is also provided with at least one magnetic attraction point 1.

When the number of the magnetic attraction points 1 of the front roller 8 and the rear roller 7 is multiple (plural), the magnetic attraction points 1 are embedded on the corresponding rollers at intervals in a uniformly distributed manner. In the most efficient embodiment, two or 4 magnets are symmetrically embedded on the roller of the front roller, and two magnets are symmetrically embedded on the roller of the rear roller.
As shown in fig. 4, as a second preferred embodiment, the magnetic attraction points 1 may be provided on the conveyor belt 3, and the number of the magnetic attraction points 1 is one, and the magnets are fixed on the conveyor belt 3. Or the number of the magnetic attraction points 1 is plural, the magnetic attraction points are arranged on the conveyor belt 3 at intervals, and the magnetic attraction points (the magnets) are fixed on the conveyor belt 3, and the intervals between the magnetic attraction points are larger than the width of the magnetic attraction mahjong, so that the mahjong is prevented from being attracted by the next magnet immediately after being far away from the last magnet, and cannot fall into the mahjong stacking groove; the mahjong tile stacking groove is also provided with a mahjong tile blocking plate structure for blocking mahjong tiles from continuously moving along with the conveying belt.
In order to ensure that mahjong pieces can smoothly fall into the mahjong stacking groove, the mahjong piece blocking plate structure 4 is a vertical mahjong piece blocking plate arranged on one side of the mahjong piece stacking groove 6 towards the direction of the front end roller 8, and the distance between the highest point of the mahjong piece blocking plate structure 4 and the nearest conveying belt 3 opposite to the highest point is smaller than the thickness of one mahjong piece 5.

The guard board structure 11 is a vertical breast board, and the middle section of the breast board is arc-shaped. The arc structure in the middle section can make the mahjong better rotate and transition. Of course, the guard structure 11 may be other structures capable of realizing the functions thereof.
When the conveyor belt 4 is selected, a wide belt (belt) or a round belt (round belt is more beneficial to the conveying of corners and has more obvious design advantages) can be selected according to specific structural design. Fig. 1 is a broadband structure, and fig. 2 is a circular band structure.
1-3, When the card picking and stacking mechanism is used, the front roller adsorbs and transfers the magnetic mahjong cards to the conveyor belt through the magnetic attraction points (magnets) arranged on the rollers of the card picking and stacking mechanism (clockwise rotation transmission in FIG. 1) to finish card picking operation; under the drive of the drive unit, the front end roller and the rear end roller both rotate, and the conveyor belt also moves clockwise; the front roller drives the rear roller to roll together through the conveyor belt, so that the mahjong pieces are transported. When the mahjong pieces move to the rear-end roller, the magnetic attraction points (magnets) on the roller of the rear-end roller attract the magnetic mahjong pieces, the mahjong pieces are turned over from the upper part of the roller to the lower part of the roller under the drive of the rear-end roller, when the magnets on the roller rotate along with the roller to leave the mahjong pieces, the mahjong pieces lose the magnetic attraction and fall into the mahjong stacking groove (of course, in the best embodiment, a mahjong stacking groove can be provided with a mahjong blocking plate structure for more accurate placement), and the steps are repeated circularly until all mahjong pieces (generally two mahjong pieces) which are required to be stacked are stacked in the stacking groove; and then pushing out the folded mahjong pieces by the mahjong pushing mechanism, and continuing to repeat the next mahjong piece picking and stacking operation by the mahjong piece picking and stacking mechanism.
In the second embodiment, as shown in fig. 4, when the card picking and stacking mechanism of the present invention is in use, the magnetic attraction points (magnets) arranged on the conveyor belt attract the mahjong tiles at the front end roller (anticlockwise rotation transmission in fig. 3), so as to complete the card picking operation; in fig. 4, the tile blocking plate structure is positioned on the right side of the tile stacking groove, when the mahjong tile moves to the position of the rear end roller and is overturned below the roller, the mahjong tile touches the tile blocking plate structure, the mahjong tile is blocked and cannot continuously advance along with the conveyor belt and the corresponding magnet, at the moment, the magnet can be far away from the mahjong tile along with the conveyor belt, the mahjong tile falls into the tile stacking groove under the action of gravity of the mahjong tile under the condition of losing magnetic attraction force, and the mahjong tile which is required to be stacked subsequently is obtained by circularly repeating the steps. Of course, when the magnetic attraction points are arranged on the conveyor belt, mahjong tiles can be transported from above in a clockwise manner like the embodiment, and the tile blocking plate structure is positioned at the left side of the tile stacking groove (the tile blocking plate structure is arranged at one side of the tile stacking groove towards the front end roller).
The mahjong tile stacking groove is skillfully arranged below the mahjong tile picking and conveying mechanism, and the magnetism and self gravity of the mahjong tiles are fully utilized, so that the mahjong tiles can be well stacked without a lifting mechanism; the whole method and the mechanism are scientific and reasonable in design, a large number of control components and lifting driving parts are saved, and the manufacturing cost of the mahjong machine is greatly reduced; in addition, the upper structure and the lower structure of the card stacking groove and the conveying mechanism fully utilize the three-dimensional space, so that the utilization of the plane space is reduced, the comprehensive layout transformation of the automatic mahjong machine is facilitated, and the design space of the automatic mahjong machine is greatly expanded.
