Description

Technical Field

[0001] The invention belongs to the field of mahjong machine manufacturing, and in particular relates to a mahjong machine and a card picking and transporting system thereof. Background Art

[0002] Mahjong is widely loved by the people as a leisure and entertainment tool, and is listed as a sports competition. The square mahjong tiles of traditional mahjong machines are parallel to the edges of the table after they are raised to the table, and the mahjong tiles are very close to the edge of the table, and the position is unreasonable. Before drawing the tiles, the players need to manually move the mahjong tiles forward and place them diagonally to the appropriate position. In the process of moving the mahjong tiles, the mahjong tiles are easy to fall over, which brings inconvenience to the players.

[0003] Chinese patent document CN200966910Y discloses a mahjong machine with a ramped card loading method, which has a table top with a card loading opening in the center, four rectangular windmill-shaped card output openings arranged on the table top and inclined at an angle to the edge of the table top, four arc-shaped card storage slots arranged in a windmill shape below the table top, a card delivery pusher is installed at the end of each card storage slot, and a card raising plate is provided on each card output opening, one end of the card raising plate is hinged with the card output opening, and the other end is movably connected with a card raising mechanism, and the four card output openings are arranged in a windmill shape. When loading cards, a part of the mahjong tiles first arrive on the table top along the card raising plate, and the remaining part of the mahjong tiles are located on the card raising plate, and finally the card raising mechanism raises the mahjong tiles on the card raising plate to the table top. Although this roller coaster-style mahjong machine can tilt the mahjong tiles after they reach the table, there is a gap between the mahjong tiles on the ascending board and the mahjong tiles that have arrived on the table before. Therefore, players still need to manually arrange the mahjong tiles after the ascending board is ascended, and the inconvenience caused to players has not been completely solved.

[0004] Chinese patent document CN109381855A discloses a mahjong machine, in which the mahjong tiles on the four sides of the mahjong machine are lifted onto the mahjong table top at one time in the form of being inclined to the four sides of the mahjong table top and close to the center of the mahjong table top. However, the layout of the conveying mechanism, stacking and lifting mechanism and card loading mechanism on the four sides of the mahjong machine is not reasonable enough, resulting in only one lifting board bracket being set at the bottom of each lifting board. In order to ensure that the lifting board can be lifted and lowered, the lifting boards of every two adjacent lifting boards of the loading mechanism are connected by a fixing plate, and the four lifting boards on the four sides must be lifted and lowered synchronously, because the four lifting boards are connected as one and have a large volume, and the lifting and lowering synchronization of the lifting boards driven by four loading motors is difficult, so the action stability of the loading mechanism is poor and it is easy to get stuck and damaged. In addition, due to the layout restrictions, the height difference between the height of the card outlet of the conveying mechanism and the descending height of the lifting board is large, the lifting span of the card receiving seat in the stacking and lifting mechanism is too large (greater 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 confused.

[0055] The lifting drive mechanism of the card support plate 71 can adopt a flat push card lifting device as described in Chinese patent document CN209645828U. However, it is preferred to adopt the structure of this embodiment. In this embodiment, Fig.13 , Fig.14 and Fig.15As shown, the lifting drive mechanism of the card supporting plate 71 includes a card loading support frame 711 and a card loading crank 716. The bottom of the card supporting plate 71 is connected to the card loading shell 70 for upward and downward sliding via two card loading guide shafts 712 and a card loading guide shaft seat 713. A card loading support frame 711 is provided on each side of the bottom of the card supporting plate 71. A card loading cam curve 7110 is provided at the bottom of the card loading support frame 711. The push card loading motor 76 cooperates with the card loading cam curves 7110 on the two card loading support frames 711 through the two card loading cranks 716, thereby driving the card supporting plate 71 to lift and lower. The card loading support frame 711 near the card inlet of the horizontal push card loading device 7 on the card supporting plate 71 is arranged at the corner position of two adjacent card feeding devices 5, and the card loading support frame 711 is closer to the shuffling plate 2 than the other card loading support frame 711 on the same card supporting plate 71, and preferably the card loading support frame 711 is located on one side of the card outlet of one card feeding device 5 (close to the inner side of the shuffling plate 2), and preferably the card loading support frame 711 is arranged on the outer side of the connecting wall 53 between the two card feeding devices 5. In this way, the card loading support frame 711 and the card loading crank 716 are arranged at the corner connection part space of the two card feeding devices 5, so that the lifting and lowering of the card supporting plates 71 of the four-way horizontal push card loading devices 7 are driven by their respective horizontal push card loading motors 76, the action is more reliable, and the machine stability is better. In a preferred embodiment, the card loading support frame 711 and the card loading crank 716 are arranged tilted relative to the card supporting plate 71 to make full use of the space. In a preferred embodiment, the two card loading guide shafts 712 on the card supporting plate 71 are symmetrically arranged, wherein the card loading guide shaft 712 close to the card inlet of the horizontal push card loading device 7 and its matching card loading guide shaft seat 713 are both located at the corner positions of two adjacent card delivering devices 5. This not only avoids the interference between the card supporting plate 71 and the card delivering device 5 below it, but also fully reduces the descending height of the card supporting plate 71, and the lifting and lowering of the card supporting plate 71 is more stable and reliable.

[0056] The push drive mechanism of the push plate 73 can adopt the structures disclosed in Chinese patent documents CN207627889U, CN206577363U and CN209679477U. Figures 15 to 17As shown, the push drive mechanism of the card pushing plate 73 includes a card pushing frame 731, a first push lever 732, a card pushing cam 733, a second push lever 734, a push shaft 735 and a connecting shaft 736. The card pushing plate 73 is fixed on the card pushing frame 731. The upper end of the first push lever 732 is hinged to the front of the card pushing frame 731, and the lower end of the first push lever 732 is installed on the connecting shaft 736. The upper end of the second push lever 734 is hinged to the rear of the card pushing frame 731, and the lower end of the second push lever 734 is installed on the push shaft 735. The push shaft 735 is connected to the push card loading motor 76 in a transmission manner. The horizontal push shaft 735 and the connecting shaft 736 are both installed on the card loading housing 70, and the connecting shaft 736 is located on the inner side of the horizontal push shaft 735. A card pushing cam 733 is fixed on the horizontal push shaft 735. The card pushing cam 733 pushes the first horizontal push lever 732, and the second horizontal push lever 734 is given reset potential energy through the spring 737. In this way, a four-bar linkage is formed between the card pushing frame 731, the first horizontal push lever 732, the second horizontal push lever 734 and the card loading housing 70. The horizontal push shaft 735 pushes the first horizontal push lever 732 through the card pushing cam 733, so that the card pushing frame 731 and the card pushing plate 73 push the cards inward. In this way, the structure is simple and the action is reliable and stable. Preferably, the first horizontal push lever 732 and the second horizontal push lever 734 are respectively arranged in pairs on the left and right, and the two first horizontal push levers 732 are fixed and moved synchronously by a connecting piece, and the card pushing cam 733 can directly push the connecting piece, and the two second horizontal push levers 734 can also be fixed and moved synchronously by a lever connecting piece 7341. Preferably, the spring 737 is a torsion spring sleeved on the horizontal push shaft 735, one end of the spring 737 is connected to the second horizontal push lever 734, and the other end of the spring 737 is connected to the card loading housing 70. Preferably, a detection circuit board 738 for detecting the rotation position of the horizontal push shaft 735 is provided on the card loading housing 70.

[0057] The card-carrying plate 72 can adopt the structure disclosed in the Chinese patent document CN109381855A, and the card-carrying plate 72 is fixed to the upper part of the card-loading shell 70. However, the height difference between the card outlet height of the card-feeding device 5 and the height difference between the card-carrying plate 71 and the lowest position is relatively large (greater than the thickness of two mahjong tiles), resulting in the card-carrying block 61 in the card-pushing device 6 having a large lifting span (greater than the thickness of two mahjong tiles), low efficiency in stacking and pushing cards, unstable operation, and easy confusion of mahjong tiles. Therefore, it is preferred to use the card-carrying plate 72 to lift up and down, so as to reduce the lifting span of the card-carrying block 61 in the card-pushing device 6 and improve the efficiency and stability of stacking and pushing cards. Figures 16 to 18As shown, in this embodiment, the lifting drive mechanism of the card bearing plate 72 includes a card raising crank 721 and a card raising support frame 723. The bottom of the card bearing plate 72 is connected to the card loading housing 70 by sliding up and down through a card raising guide shaft 724 and a card raising guide shaft seat 725. Two card raising support frames 723 are arranged on both sides of the bottom of the card bearing plate 72. The bottom of the card raising support frame 723 is provided with a card raising cam curve. The horizontal push card loading motor 76 pushes the card raising support frame 723 through the card raising crank 721 to drive the card bearing plate 72 to rise and fall. In this embodiment, the card bearing plate 72 has at least two stop positions: when the first stop position is low, the card bearing plate 72 receives two mahjong tiles stacked into one pile pushed by the card pushing device 6; when the second stop position is high, the card pushing plate 73 pushes the multi-pile mahjong tiles arranged on the card bearing plate 72 to the card supporting plate 71. In this way, the card-bearing plate 72 descends to a low position to receive the mahjong tiles pushed from the card-pushing device 6. When the cards are pushed horizontally, the card-bearing plate 72 rises to a high position to push the mahjong tiles onto the card-supporting plate 71. The lifting span of the card-bearing block 61 in the card-pushing device 6 is greatly reduced (about the thickness of a mahjong tile), and the efficiency and stability of stacking and pushing cards are improved. Preferably, an inner baffle wall 74 is provided on the inner side of the card-bearing plate 72, and an outer baffle wall 75 is provided on the outer side of the card-bearing plate 72. The inner baffle wall 74 and the outer baffle wall 75 are integrally formed or fixedly connected with the card-loading housing 70. When the card-bearing plate 72 rises upward, its height is higher than the inner baffle wall 74, so that the mahjong tiles on the card-bearing plate 72 can be prevented from falling in a disorderly manner. Preferably, the other end (the end opposite to the card-inlet) of the card-bearing plate 72 extending in the length direction is provided with a baffle 720, and the baffle 720 is fixed on the card-loading housing 70. The baffle 720 also blocks one end of the card-supporting plate 71.

[0058] In other embodiments, the flat-pushing card-loading device 7 having the above-mentioned liftable card-receiving plate 72 can also be combined with the card-pushing device 6 for pushing a single mahjong tile, so that the card-receiving plate 72 has at least three stop positions: in the first stop position, the card-receiving plate 72 receives the single mahjong tile pushed by the card-pushing device 6 and arranges it to form a first layer of mahjong tiles; in the second stop position, the card-receiving plate 72 receives the single mahjong tile pushed by the card-pushing device 6 and arranges it to form a second layer of mahjong tiles; in the third stop position, the card-pushing plate 73 pushes the multiple piles of mahjong tiles arranged on the card-receiving plate 72 onto the card-supporting plate 71.

[0059] The card-loading transmission mechanism is as follows: Fig.16 and Fig.17As shown, it includes a main transmission shaft 77, a first transmission shaft 714, a first card-loading shaft 715, a second card-loading shaft 717 and a card-lifting shaft 722, which are respectively installed in the card-loading housing 70 through bearings or shaft seats 78, and the output shaft 761 of the horizontal push card-loading motor 76 is respectively connected to the main transmission shaft 77 and the first transmission shaft 714 through a transmission bevel gear set 79. The card loading crank 716 on the side of the card supporting plate 71 close to the card pushing device 6 is fixed on the first card loading shaft 715, and the first card loading shaft 715 is connected to the first transmission shaft 714 through a transmission bevel gear group 79. The card loading crank 716 on the side of the card supporting plate 71 away from the card pushing device 6 is fixed on the second card loading shaft 717, and the second card loading shaft 717 is connected to the main transmission shaft 77 through a transmission bevel gear group 79. The card raising crank 721 on the side of the card bearing plate 72 close to the card pushing device 6 is fixed on the motor output shaft 761, and the card raising crank 721 on the side of the card bearing plate 72 away from the card pushing device 6 is fixed on the card raising shaft 722, and the card raising shaft 722 is connected to the main transmission shaft 77 through a transmission bevel gear group 79, and the main transmission shaft 77 is connected to the push shaft 735 through a transmission gear group 739. In this way, a horizontal card-pushing motor 76 drives the card-supporting plate 71, the card-bearing plate 72 and the card-pushing plate 73 to achieve card-lifting, card-pushing and card-loading.

And preferably, the square card blocking frame 9 is integrally formed in a windmill shape, which has a simple structure and is easy to install. The square integrated card blocking frame is provided with a central large hole, and the central lifting device 4 is arranged therein. And preferably, the card blocking frame 9 is provided with an opening at a position between the card inlet of the card holding plate 72 and the card holding block 61 to avoid affecting the card pushing of the card pushing head 62 of the card pushing device 6.
