As shown in fig. 10, in the process of lifting the tile lifting support plate, the distance d2 between the corner of the mahjong tile placed on the movable end of the tile lifting support plate and the rotation axis of the tile lifting support plate is larger than the distance d1 between the movable end of the tile lifting support plate and the rotation axis of the tile lifting support plate; in order to prevent mahjong tiles with larger gaps or edges from being bumped with the table top of the mahjong machine, the disposable mahjong tile feeding machine in the prior art adopts a tile feeding push head to push the mahjong tiles for a small distance forwards after pushing the mahjong tiles to the tile lifting support plate; however, in the staged feeding process, the first feeding is to push a part of the mahjong tiles continuously and tightly arranged in the tile storage groove to the tile lifting supporting plate, and in the process, the tile lifting pushing head cannot push a small distance forward, so that the mahjong tiles close to the tile outlet of the tile storage groove fall or are clamped between the tile lifting supporting plate and the tabletop plate. The cover plate which can be opened upwards is arranged, so that the mahjong tiles at the edge of the tile lifting support plate can jack up the cover plate in the tile lifting support plate lifting process, and after the tile lifting support plate is flush with the mahjong machine table top, the cover plate returns, and a larger gap between the tile lifting support plate and the mahjong machine table top or collision between the mahjong tiles at the edge and the mahjong machine table top is avoided. Therefore, the game can be played by adopting staged tile feeding, players can vertically set up six piers or thirteen mahjong tiles to be played for the first time, the manual tile feeding and arranging processes are omitted, the operation of the players is simpler and more convenient, and the entertainment experience is better. And, adopt the stage to put on the tablet, can be after six piers of first time or thirteen pieces of post, send the tablet device and push away the tablet device and continue to send mahjong into the storage tank and store, the storage tank just need not once store all mahjong pieces that one side needs (for example four directions each 18 piers), only need store once the mahjong pieces quantity of putting on the tablet can, therefore can shorten the length of storage tank greatly, and then make the overall arrangement of mahjong machine host computer more nimble compact, mahjong machine volume is littleer, perhaps can use bigger mahjong pieces on the same volume model.
In this embodiment, one side of the cover 1101 may be hinged to the tile lifting bracket 602, the tile lifting bracket 501 or the table top 11 of the mahjong machine, and the other side of the cover 1101, which is close to the tile inlet of the tile lifting slot, may be turned upwards, where the rotation axis of the cover 1101 is parallel to the rotation axis of the tile lifting supporting plate 601. Thus, the cover plate and the tile lifting supporting plate are in a split mode, the resistance of the cover plate to the tile lifting supporting plate and the mahjong tiles on the tile lifting supporting plate is smaller, and the tile lifting and the mahjong tile mess cannot be influenced. The cover 1101 is spring-returned to be flush with the table top 11 of the mahjong machine. Therefore, the defects that the cover plate is reset slowly only by gravity and is easy to pull up and the like can be avoided. The tile lifting bracket 602, the tile lifting bracket 501 or the mahjong machine table top 11 is provided with a limiting component for limiting the cover plate 1101 to rotate below the mahjong machine table top 11. In the preferred embodiment, as shown in fig. 8 and 9, one side of the cover 1101 is hinged to the table top 11 of the mahjong machine by a hinge, a fixed portion 1102 of the hinge is fixedly connected to the bottom of the table top 11 of the mahjong machine, a movable portion 1105 of the hinge is fixedly connected to the bottom of the cover 1101, a torsion spring 1106 for giving a downward rotation trend to the movable portion 1105 is sleeved on a rotating shaft 1104 of the hinge, a limiting portion 1103 for limiting the downward rotation range of the movable portion 1105 is formed on the fixed portion 1102 of the hinge in an extending manner, and the rotating shaft 1104 of the hinge is parallel to the rotation axis of the tile lifting supporting plate 601. Thus, the cover plate and the tile lifting supporting plate are in a split mode, the resistance of the cover plate to the tile lifting supporting plate and the mahjong tiles on the tile lifting supporting plate is smaller, and the tile lifting and the mahjong tile mess cannot be influenced. The hinge type and torsion spring reset are adopted, the structure is simple and reliable, the volume is small and exquisite, and the cost is low.
The mahjong machine with the cover plate structure can implement the same disposable tile feeding method as the prior art, and the tile feeding pushing head does not need to push the mahjong tiles a small distance more forwards after pushing the mahjong tiles to the tile lifting supporting plate, so that the machine adjustment is simpler and more convenient. But the present invention preferably employs staged up cards as follows:
a method for feeding mahjong pieces of a mahjong machine comprises the mahjong machine, wherein when the mahjong pieces are stored, a mahjong piece feeding device picks up the mahjong pieces and pushes the mahjong pieces into a mahjong piece storage groove by a tile pushing device; when the mahjong machine receives a first tile-feeding signal, the tile-feeding supporting plate of the tile-feeding device descends, the tile-feeding pushing head firstly pushes a part of mahjong tiles (generally six piers and half or thirteen mahjong tiles) in the tile-storing groove to lift the tile-feeding supporting plate, as shown in fig. 4, during the lifting process of the tile-feeding supporting plate, the mahjong tiles on the tile-feeding supporting plate jack up the cover plate, as shown in fig. 5, until the mahjong tiles lift up the tabletop, the cover plate resets, as shown in fig. 6, and a player waits for taking the mahjong tiles on the tabletop; after receiving the second tile-feeding signal, the tile-lifting supporting plate descends again, the tile-feeding pushing head pushes the remaining mahjong tiles in the tile-storing groove to the tile-lifting supporting plate, and the tile-lifting supporting plate is lifted to feed the mahjong tiles to the table top.
In the embodiment, when storing mahjong pieces, the single mahjong piece on first is pushed by the tile pushing head in the tile feeding assembly to be sent into the tile storage groove, and the rest mahjong pieces on each side are stacked into a pier by the tile pushing device to be sent into the tile storage groove.
In another embodiment: when the mahjong machine sends a part of mahjong tiles in the tile storage groove to the tabletop, the tile pushing head returns to the outside of the tile inlet of the tile storage groove, and the tile sending device continues to send out mahjong tiles and pushes the mahjong tiles into the tile storage groove by the tile pushing device. Therefore, the length requirement of the mahjong storage groove can be shortened, and the volume of the mahjong machine is reduced.
The method of arranging the mahjong tiles in stages is not limited to the six-pier half mahjong tiles or the six-pier tiles, but can be to arrange thirteen mahjong tiles in a row (namely, thirteen mahjong tiles are arranged in a row instead of being stacked in one pier up and down, as shown in fig. 7), and can be any other mahjong tiles with a certain number according to playing requirements. When a row of thirteen mahjong tiles are adopted for first feeding, the tile pushing device only pushes a single mahjong tile into the tile storage groove, rather than pushing two mahjong tiles into the tile storage groove after piling up two mahjong tiles. There are various forms of how to push a single mahjong tile on the existing tile pushing device in the stacking pushing mode, for example: the card bearing block of the card pushing device stops moving to push cards into the card storage groove only by the movement of the card pushing head; or, although the tile bearing block moves up and down, the tile feeding device waits for the tile pushing head to push away one tile and then feeds out the next tile after feeding out one tile to the tile bearing block; or, the thirteen mahjong tiles on the first are pushed by the tile pushing head to be sent into the tile storage groove, and the rest mahjong tiles on each side are stacked into a pier by the tile pushing device to be sent into the tile discharge storage groove, so that the structure is simple, and the action is reasonable.
The card feeding bracket 501 is provided with a sensor for detecting the position state of the card feeding push head 505 and/or the mahjong pieces: in the card feeding assembly adopting the disposable card feeding method, at least two sensors are needed and are respectively used for detecting and obtaining the position information when the card feeding push head stays outside the card feeding port of the card storage groove and waits for pushing a card, and the position information when the card feeding push head stays outside the card discharging port of the card storage groove and waits for lifting the card supporting plate to lift the mahjong card on the tabletop. In the card feeding assembly adopting the staged card feeding method, at least three sensors are needed and are respectively used for detecting and obtaining the position information of the card feeding push head when the card feeding push head stays outside the card feeding port of the card storage groove and waits for pushing a card, the position information (sensor 504) of the card feeding push head when a part of mahjong cards in the card storage groove are pushed to rise the card supporting plate, and the position information of the card feeding push head when the card feeding push head stays at the card discharging port of the card storage groove and waits for the card lifting supporting plate to lift the mahjong cards to the table surface. The accurate position of the card feeding push head is determined through the sensor, and the card feeding push head is fed back in time, is convenient to control, acts accurately and reduces faults.
Preferably, a sensor for detecting mahjong pieces or a pushing head can be arranged at the card inlet and/or the card outlet of the card storage groove. The sensor for detecting the card pushing head can be in a direct detection mode or an indirect detection mode, for example, the driving mechanism of the card pushing head is subjected to position detection to obtain corresponding position information of the card pushing head, for example, the position information of the steel wire rope is detected to obtain the position information of the card pushing head, and for example, a stepping motor or a motor with the position sensor is adopted, and the position information of the card pushing head is converted by recording the rotation travel information of the motor. The sensor may also be a sensor provided near the tile storage slot or the tile lifting slot for counting the number of tiles passing. The sensor may be a hall sensor, a photoelectric sensor, an ultrasonic sensor, or a contact sensor such as a limit switch.
The first card-up signal is typically generated by the player pressing a control button. The second tile feeding signal may be generated by the player pressing a control button, or may be generated by a sensor capable of detecting whether the player removes the mahjong tile on the tile lifting tray, or may be an optical eye or a gravity sensor provided on the tile lifting tray 601, or may be other sensors provided on a table or a tile lifting stand for detecting the action state and/or the load-bearing state of the tile lifting tray.
