Description

Mahjong machine and mahjong tile arranging method

[ technical field ] A method for producing a semiconductor device

The invention belongs to the field of mahjong machine manufacturing, and particularly relates to a mahjong machine and a mahjong tile sorting method.

[ background of the invention ]

Mahjong is a popular tool for people as a recreational tool and is listed as a sports event. The mahjong tiles in the four directions of the traditional mahjong machine are parallel to the edges of the four directions of the table top after being lifted to the table top, the mahjong tiles are close to the table side and unreasonable in arrangement, a player needs to manually move the mahjong tiles forward and obliquely to a proper position before the mahjong tiles are touched, and the mahjong tiles are easy to topple over and bring inconvenience to the player in the process of moving the mahjong tiles.

Patent documents with publication number CN200966910 and the like disclose a slope mahjong machine with a mahjong tile feeding mode, which comprises a table board, wherein a mahjong tile feeding port is arranged at the center of the table board, four rectangular mahjong tile discharging ports are arranged on the table board and are inclined at an angle with the side line of the table board, four arc mahjong tile storage grooves which are also arranged in a windmill shape are arranged below the table board, a mahjong tile feeding pushing head is arranged at the tail end of each mahjong tile storage groove, a mahjong tile lifting plate is arranged on each mahjong tile discharging port, one end of each mahjong tile lifting plate is hinged with each mahjong tile discharging port, the other end of each mahjong tile lifting plate is movably connected with a mahjong tile lifting mechanism, and the four mahjong tile discharging ports are arranged in a windmill. When the mahjong tiles are loaded, a part of the mahjong tiles reach the desktop along the tile lifting plate firstly, the rest mahjong tiles are positioned on the tile lifting plate, and finally the mahjong tiles on the tile lifting plate are lifted to the desktop by the tile lifting mechanism. Although the roller coaster type mahjong machine realizes inclined placement of mahjong tiles after the mahjong tiles reach a table top, gaps are easy to exist between the mahjong tiles on the tile lifting plate after the mahjong tiles are lifted to the table top and the mahjong tiles reaching the table top before, so that the inconvenience caused to players is not completely solved because the mahjong tiles are manually arranged by the players after the mahjong tiles are lifted by the tile lifting plate.

Patent documents CN109381855 and the like disclose a mahjong machine, wherein mahjong tiles in four directions of the mahjong machine are respectively inclined to the four edges of a mahjong table panel and are lifted onto the mahjong table panel at one time in a manner of being close to the center of the mahjong table panel. However, the four-direction conveying mechanism, the stacking and lifting and pushing mechanism and the tile feeding mechanism of the mahjong machine are not reasonable enough in layout, so that only one tile lifting plate support can be arranged at the bottom of each tile lifting plate, in order to ensure that the tile lifting plates can lift, the tile lifting plates of every two adjacent tile feeding mechanisms are connected through the fixing plate, the four tile lifting plates of the four directions need to lift synchronously, and the four tile lifting plates are connected into a whole and have a large volume, and are driven by the four tile feeding motors to lift synchronously and difficultly, so that the motion stability of the tile feeding mechanism is poor, and the tile feeding mechanism is easy to block and damage. And the height difference between the height of the mahjong outlet of the conveying mechanism and the descending height of the mahjong lifting plate is large, the lifting span of the mahjong receiving seat in the stacking and lifting pushing mechanism is too large (larger than the thickness of two mahjong tiles), the stacking and pushing efficiency is low, the operation is unstable, and the mahjong tiles are easy to be disordered and clamped.
