Description

Double-layer shuffling disk device and automatic mahjong machine applying same

Technical Field

The utility model relates to a double-layer shuffling tray device and an automatic mahjong machine using the same.

Background

When mahjong tiles are pushed to fall from a desktop to a big shuffling tray, large tile falling noise is generated due to high fall, the use experience of consumers is poor, and the neighborhood relation is particularly influenced once a neighbor has been disturbed to have a rest.

Secondly, when the shuffling large disc rotates, the card turning magnet at the edge of the shuffling large disc is responsible for turning the cards (one side of the mahjong is upward with characters), the square card sucking wheel is responsible for sucking the cards and transporting the cards (one side of the mahjong is upward with characters is sucked and transported to the machine head), only when the distribution quantity of the mahjong in the card turning and sucking areas is proper, the efficiency of turning and sucking the cards is highest, and when the quantity of the mahjong in the card turning and sucking areas is crowded, the card stacking and squeezing during the turning and sucking processes are low, and the noise is large during the card stacking and squeezing processes.

When the total number of the mahjong tiles is less (88), the mahjong tiles directly falling into the middle and the edges of the shuffling large plate are not crowded, the edge card turning and card feeding efficiency of the card shuffling large plate and the card feeding wheel device is higher, the card arranging time is faster, the cards are not easy to be clamped by the card shuffling large plate and the card feeding wheel device, and the load of a large plate motor is lighter. However, the number of the mahjong tiles in different areas is different, when the number of the mahjong tiles pushed into the shuffling large disk is increased, the number of the mahjong tiles directly falling into the middle part and the edge of the shuffling large disk is crowded, and when the mahjong tiles are sent by the mahjong tile strip shifting device after the large disk rotates, the mahjong tiles at the edge of the shuffling large disk are particularly crowded, the mahjong tile turning efficiency at the edge of the shuffling large disk and the mahjong tile feeding efficiency on the mahjong tile sucking wheel device are both rapidly reduced, the mahjong tile arranging time is greatly increased, the mahjong tiles are easy to be jammed in the shuffling large disk and the mahjong tile sucking wheel device, and the load of a motor of the large disk is large. Meanwhile, the mahjong tiles have more than ten specifications of 38mm-58mm, and under the condition of the same total number of tiles, the bigger the tile specification is, the more likely the tiles are jammed by the tile shuffling large disk and the tile suction wheel device, and the larger the motor load of the large disk is.

With the increase of the total number of local mahjong tiles and the increase of the size of the local mahjong tiles of consumers, the motor power of the large-disk corresponding to the mahjong machine is also increased, and the diameter of the shuffling large-disk and the motor power specification can only be improved aiming at the change.

The double-deck shuffling device in the above embodiments all adopts the buffer disk 2 integrally formed by hard materials, taking the first embodiment in fig. 2 as an example, an annular mahjong tile arranging area 100 is formed between the outer circumference of the buffer disk 2 and the mahjong tile shuffling large disk 1, an annular mahjong tile storing space for containing mahjong tiles is also formed between the lower surface of the buffer disk 2 and the mahjong tile shuffling large disk 1 on the inner side of the annular mahjong tile arranging area, and part of the mahjong tiles in the annular mahjong tile arranging area can enter the interlayer annular mahjong tile storing space between the buffer disk 2 and the mahjong tile shuffling large disk 1 for temporary storage, so that the volume of the mahjong tile arranging space is increased. The buffer disc 2 is of a hard structure, so that the internal height of the sandwich structure of the annular mahjong arranging space is fixed, small-size mahjong tiles can easily freely enter and exit the annular mahjong storing space in the process of arranging and moving on the large shuffling disc, but the mahjong tiles can be easily clamped in the annular mahjong storing space between the buffer disc and the large shuffling disc when the large-size mahjong tiles are treated, and faults are caused.

To the above problem, the utility model also provides a buffer disc solution that can be used to above embodiment. Referring to fig. 16, a circle of flexible brushes 23 is arranged in an annular region corresponding to the annular tile storage space of the buffer disk 2 in the figure, that is, the region of the buffer disk 2 inside the mounting ring 201 adopts a hard upper surface, the upper surface is used as a buffer region to directly receive mahjong tiles falling from the tile inlet, the flexible brushes 23 are uniformly arranged in the region of the buffer disk 2 outside the mounting ring 201, and the flexible brushes 23 extend downwards along the circumferential direction of the upper surface of the buffer disk, so that the upper surface of the whole buffer disk 2 is still a conical surface with a high middle part and a low periphery. Due to the arrangement of the flexible brush 23, when the mahjong tiles on the buffer disc 2 fall on the big shuffling disc 1, the flexible brush 23 can also provide a part of bearing force, so that the impact of the mahjong tiles falling on the big shuffling disc 1 from the buffer disc 2 is further reduced, and the noise is reduced; meanwhile, when the mahjong tiles in the outer ring annular tile arranging area 100 enter the inner annular tile storing space, even if the size of a part of the mahjong tiles exceeds the height of the annular tile storing space, the flexible brush 23 can be bent upwards to adapt to the mahjong tiles and cannot clamp the mahjong tiles. The arrangement of the buffer disk 2 can improve the adaptability of the double-layer shuffling disk device to mahjong tiles with different sizes.

The automatic mahjong machine adopting the double-layer shuffling tray device has the advantages that the buffer tray is arranged above the shuffling large tray or the mahjong shifting strip, so that the fall of mahjong tiles entering the shuffling barrel is reduced, when the mahjong tiles are pushed down from a table top, the fallen mahjong tiles are firstly received by the buffer tray and then fall on the shuffling large tray or slightly fall on the shuffling large tray, and the fall of the mahjong tiles is reduced, so that the falling noise of shuffling is obviously reduced, the use experience of consumers is good, the rest of neighbors is not disturbed, and the neighborhood relation is not influenced. Secondly, the internal space of the mahjong shuffling barrel of the mahjong machine is divided into a buffer area and an annular mahjong arranging area through the buffer disc, the three-dimensional space inside the mahjong shuffling barrel is reasonably utilized, mahjong is effectively distributed, the mahjong arranging efficiency is high, and the mahjong shuffling barrel can be more suitable for mahjong of different sizes and different quantities.
