Description

Mahjong machine and tile pushing machine head thereof

Technical Field

The invention relates to the technical field of mahjong machine manufacturing, in particular to a mahjong machine and a tile pushing machine head thereof.

Background

The existing full-automatic mahjong machine can integrate the functions of shuffling, dice throwing and the like, and provides great convenience for playing cards for people. However, the prior full-automatic mahjong machine is basically provided with only four outlets, then the mahjong is conveyed to the mahjong table surface from the four outlets, and the mahjong pieces still need to be pushed, cut and stacked manually during playing, so that the operation is troublesome, and the situation of wrong cutting can occur, and the mahjong pieces can be shuffled again.

In order to solve the problem, chinese patent No. CN200920118048.7 discloses an automatic mahjong machine, which includes a mahjong machine table top and a main machine arranged below the mahjong machine table top, an inner checkered plate is arranged in the main machine, outer checkered plates are arranged on the outer sides of the inner checkered plate, 4 outer checkered plates are connected through 4 arc transition sections to form an annular track for bearing mahjong tiles, an annular pushing device for pushing the mahjong tiles is arranged above the annular track, a sliding rail is arranged below a tile pushing machine head, the tile pushing machine head is arranged between an inner pushing port and an outer pushing port in a sliding manner under the driving of a motor, and warping devices for guiding the mahjong tiles on the annular track to the mahjong machine table top are arranged on the mahjong machine table top right above the 4 outer checkered plates. According to the automatic mahjong machine provided by the invention, thirteen cards to be grabbed by the game participants are respectively arranged on the four side cards at the outer side, so that the game participants can obtain more convenient, rapid and comfortable game experience.

The tile lifting principle of the automatic mahjong machine is as follows: the card pushing head of the card pushing head pushes cards to the outer layer lattice plate at the outer card pushing port at the beginning, when 13 cards are pushed, the control system sends out an instruction, the card pushing head drives the card pushing head to move to the inner card pushing port, and the card pushing head starts to push cards. When the card pushing head is pushed with a certain number of piers (different according to the total number of piers for playing cards), the motor of the horizontal pushing assembly rotates to drive the guide plate to fall down, and then the second layer of cards are pushed. When the 4 outer checkered plates are all full of 13 cards and the card pushing machine head moves to the inner card pushing port, the control system sends out a signal, the steel wire rope motor starts to rotate, the cards are driven to travel on the annular rail, and the cards travel to the positions waiting for being loaded. When the cards are stacked on all 1 inner checkerboard, the conveying motor is reversed, the cards remaining in the conveying device are reversed to the large plate and are conveyed to the card feeding ports of other conveying devices until the cards are stacked on all the last 4 inner checkerboard plates.

The automatic mahjong machine has the following disadvantages:

1) the conveying channel is internally provided with an outer tile pushing port and an inner tile pushing port, and the mahjong passes through the inner tile pushing port and the outer tile pushing port, so that when the tile pushing head passes through the inner tile pushing port, the mahjong can be missed to reach the outer tile pushing port, and the mahjong machine is blocked;

2) the movement of the card pushing head from the outer card pushing port to the inner card pushing port and from the inner card pushing port to the outer card pushing port requires another driving device such as a motor drive, which is high in cost.

The patent application document with the publication number of CN107519637A discloses a mahjong machine and a mahjong loading method thereof, wherein the mahjong machine comprises four groups of mahjong picking and carrying systems arranged around a shuffling tray, each mahjong picking and carrying system comprises a mahjong conveying device used for picking and conveying mahjong tiles one by one from the shuffling tray, a mahjong stacking device used for stacking two mahjong tiles into a pier, a mahjong pushing device used for pushing the mahjong tiles into a mahjong storage groove, and a slope mahjong discharging device used for conveying the arranged multi-pier mahjong tiles onto the table surface of the mahjong machine along a slope, the slope mahjong discharging device comprises a mahjong loading assembly and a mahjong lifting assembly, the mahjong loading assembly comprises a mahjong storage groove, the mahjong storage groove is bent in a large-angle arc shape, and the storage number of the mahjong tiles in the mahjong storage groove is increased; the card loading assembly and the card lifting assembly in the same group of card picking and carrying systems are directly adjacent. The mahjong machine can realize the method of playing the mahjong by stages, when storing the mahjong, the mahjong is picked up by the mahjong sending device and pushed into the mahjong storage groove by the mahjong pushing device; when the mahjong machine receives a first mahjong tile feeding signal, a mahjong tile lifting supporting plate of the mahjong tile lifting device descends, a mahjong tile feeding and pushing head firstly pushes a part of mahjong tiles (generally six piers and a half or thirteen mahjong tiles) in a mahjong tile storage groove onto the mahjong tile lifting supporting plate, the mahjong tile lifting supporting plate rises to feed the mahjong tiles onto a table top, and a player takes away the mahjong tiles on the table top; after the mahjong machine receives the second mahjong tile feeding signal, the mahjong tile lifting supporting plate descends, the mahjong tile feeding and pushing head pushes the remaining mahjong tiles in the tile storage groove to the mahjong tile lifting supporting plate, and the mahjong tile lifting supporting plate rises to feed the mahjong tiles to the table top. By adopting the scheme of pushing twice in stages, the function of the eight-opening mahjong machine can be realized by using the existing four-opening mahjong machine structure, but because the pushing head occupies the position of one block of tiles in the tile storage groove in the process from the tile feeding to the tile lifting device, the length of the tile storage groove of 18-19 blocks of tiles is needed at 17 blocks of tiles, when the mahjong machine adopting the mode is used for playing larger tiles, the length of the track of the needed mahjong machine is longer, the mahjong machine with the size of the existing machine type cannot be realized, and therefore the length of the tile storage groove of the mahjong machine needs to be reduced as much as possible.

The utility model discloses a utility model with publication number CN108635827A discloses a tile feeding structure of a three-layer mahjong machine, which comprises a circular single-layer tile channel and a circular double-layer tile channel which are overlapped up and down, wherein a motor base is arranged on the single-layer tile channel, a second motor is arranged on the motor base through a gear, a first motor is arranged on the motor base through a rotating shaft, a driven shaft on the motor base is connected with a single-layer tile turntable through a bearing, the teeth of the single-layer tile turntable are meshed with the gear, a single-layer tile deflector rod is arranged on the single-layer tile turntable, and a tile adjusting ring and a double-layer tile deflector rod arranged in the tile adjusting ring are arranged on the double-layer tile channel; after the three-layer cards enter the card channels, the second motor drives the gears to drive the single-layer card turntable to rotate, and the cards in the single-layer card channels are pushed to the table top of the mahjong machine through the single-layer card deflector rods of the single-layer card turntable; after the three-layer cards enter the card channels, the first motor drives the rotating shaft to drive the double-layer card deflector rod to rotate, and the cards in the double-layer card channels are pushed to the table top of the mahjong machine. The mahjong machine with the structure has the advantages that three mahjong tiles are stacked to form one pier, one pier of mahjong tiles are divided into a single-layer mahjong tile channel and a double-layer mahjong tile channel, and then the single-layer mahjong tile channel and the double-layer mahjong tile channel are respectively sent to the table top of the mahjong machine, so that the required rail length of the mahjong machine can be effectively shortened, but the occupied height of the mahjong tile loading structure of the mahjong machine is large, the overall height of the mahjong machine using the structure is large, particularly when large mahjong tiles are played, the existing mahjong machine cannot achieve the rail size, and when one pier of mahjong tiles are divided into the single-layer mahjong tile channel and the double-layer mahjong tile channel, the required precision of the rail boundary is extremely high, and the mahjong machine can be stuck due to slight deviation; on the other hand, the two motors are respectively used for directly or indirectly driving the two tile pushing heads to push the mahjong tiles in the single-layer tile channel and the double-layer tile channel, so that the structural complexity and the control complexity of the mahjong machine are increased, and the production cost of the mahjong machine is increased.

In this embodiment, the stacking process is as follows: in the initial state, the tile supporting plate 553 has a height matching the first tile pushing position 421, the first tile pushing head 73 can push the tiles to the tile supporting plate 553 through the first tile pushing position 421, when the first layer of tiles 10 are fully paved, the first tile feeding motor 52 drives the lifting crank 554 to rotate, so that the tile supporting plate 553 descends, the descending height is the thickness of one tile 10, and then the first tile pushing head 73 can continue to push tiles until the tiles 10 reach the designated number of piers, and the stacking is completed.

Specifically, the card pushing surface of the card pushing head 612 includes a vertical surface and an inclined surface 61232. Further preferably, the vertical surface and the inclined surface 61232 are in smooth transition; when the card-pushing head 612 pushes the card in the first card-pushing guide 63, the card-pushing surface is a vertical surface in the horizontal first linear guide 6311 and second linear guide 6321, and the card-pushing surface is an inclined surface 61232 in the first arc-shaped guide 6312 and second arc-shaped guide 6322 inclined upward.
