Description

Technical Field

[0001] The utility model relates to a card loading system for a mahjong machine. Background Art

[0002] Most existing mahjong machines use the following method for loading tiles: multiple piles of mahjong tiles are first arranged and placed on a push track. A tile receiving block is provided at the end of the push track, which is tilted upward. The tiles are then pushed onto the receiving block by a push rod. However, because the receiving block is tilted upward, the push rod pushes the tiles, causing the upper and lower tiles of a single pile to become misaligned. When the tiles on the receiving block enter the table, the upper tiles will slide slightly forward as the tiles transition from an inclined position to a horizontal position.

[0003] In the prior art, there have been studies in this regard, such as the Chinese patent application number 2017109643876, which staggers the upper and lower mahjong tiles by setting a protrusion on the pusher head. However, this setting has a limited staggering distance between the upper and lower mahjong tiles, and can only make the mahjong tiles at the back end of the entire row of tiles achieve the effect of vertical alignment, while the mahjong tiles at the front end still have the problem of misalignment. Summary of the Invention

[0004] The purpose of the utility model is to provide a mahjong machine card loading system to solve the technical problems mentioned in the above background technology.

[0005] The technical solution for achieving the purpose of the utility model is: a card loading system for a mahjong machine, comprising a base, on which a staggered card feeding mechanism and a card raising mechanism are sequentially arranged along the direction of movement of the mahjong tiles; after the staggered card feeding mechanism receives mahjong tiles arranged in piles, the mahjong tiles are fed into the card raising mechanism in a front-to-back staggered manner with the lower mahjong tiles in front and the upper mahjong tiles in the back; and the card raising mechanism raises the mahjong tiles above the table top.

[0006] Furthermore, the staggered card lifting mechanism includes a staggered card feeding track and a card pushing device, the card pushing device includes a rotating axis and a card pushing rod that performs circular motion around the rotating axis, the staggered card feeding track is arc-shaped and is arranged around the rotating axis; the card pushing rod is suitable for pushing mahjong tiles in the staggered card feeding track.

[0007] Furthermore, the card pushing device also includes a card pushing rod fixing seat, one end of the card pushing rod is fixed on the card pushing rod fixing seat; the card pushing rod fixing seat is sleeved on the rotating axis, a planetary gear is provided inside the card pushing rod fixing seat, a sun gear is provided on the rotating axis, and a ring gear is provided on the base that is concentric with the rotating axis, and the planetary gear is engaged with the sun gear and the ring gear at the same time.

[0008] Further, the pushing rod includes an upper pushing portion and a lower pushing portion, and the lower pushing portion extends with a protruding portion along the moving direction of the mahjong tiles.

[0009] Further, the staggered tile feeding track includes a first feeding track for the lower-layer mahjong tiles to slide and a second feeding track for the upper-layer mahjong tiles to slide, and the second feeding track is longer than the first feeding track.

[0010] Further, a part of the second feeding track is offset outward relative to the first feeding track.

[0011] Further, the card-lifting mechanism includes a card-bearing block, the card-bearing block includes a hinged end and a movable end, the hinged end is hinged to the base, and the movable end swings around the hinged end.

[0012] Further, when the movable end of the card-bearing block reaches the lowest position, the movable end is lower than the hinged end, and the card-bearing block is obliquely arranged to receive the mahjong tiles conveyed by the staggered tile feeding mechanism; when the movable end of the card-bearing block reaches the highest position, the card-bearing block is flush with the tabletop.

[0013] Adopting the above technical solutions, the present utility model has the following beneficial effects:

[0014] (1) The present utility model staggers the mahjong tiles up and down through the staggered tile feeding track, and then cooperates with the card-lifting mechanism to lift the mahjong tiles to the tabletop, achieving the effect of being neatly arranged up and down after the whole column of tiles is dealt.

[0015] (2) The staggered tile feeding track of the present utility model is arc-shaped. Compared with the straight and L-shaped track grooves, the space required for pushing the mahjong tiles is reduced, which is beneficial to the thin and light design of the mahjong machine. The pushing rod makes a circular motion around the rotation axis, and there is no need to connect the pushing rod through a connecting rod, simplifying the setting of the pushing rod.

[0016] (3) The rotation axis of the present utility model is fixedly connected to the pushing rod fixing seat through a planetary gear, and the pushing rod can be driven to move in the staggered tile feeding track by rotating the rotation axis.

[0017] (4) The second feeding track of the present utility model is offset outward relative to the first feeding track. Therefore, the second feeding track is longer than the first feeding track, making the moving path of the upper-layer mahjong tiles longer than that of the lower-layer mahjong tiles. When the same stack of mahjong tiles reaches the card outlet, the upper-layer mahjong tiles lag behind the lower-layer mahjong tiles. BRIEF DESCRIPTION OF THE DRAWINGS

The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and cannot be used to limit the protection scope of the present utility model.

[0031] (Embodiment 1)

[0032] See Figures 1-5 , the tile feeding system of the mahjong machine in this embodiment includes a base 1, and a misaligned tile feeding mechanism and a tile lifting mechanism are sequentially arranged on the base 1 along the moving direction of the mahjong tiles; after receiving the mahjong tiles arranged in stacks, the misaligned tile feeding mechanism feeds the mahjong tiles into the tile lifting mechanism in a front-back misaligned manner with the lower-layer mahjong in the front and the upper-layer mahjong in the back; the tile lifting mechanism lifts the mahjong tiles above the tabletop.

[0033] Specifically, see Figure 1 and 4, the misaligned card lifting mechanism includes a misaligned card feeding track 2 and a card pushing device 3. The card pushing device 3 includes a rotation axis 3-1, a card pushing rod 3-2 that makes a circular motion around the rotation axis 3-1, and a card pushing rod fixing seat 3-3. The misaligned card feeding track 2 is arc-shaped and is arranged around the rotation axis 3-1. One end of the card pushing rod 3-2 is fixed to the card pushing rod fixing seat 3-3. The card pushing rod fixing seat 3-3 is sleeved on the rotation axis 3-1, and a planetary gear 3-4 is arranged inside the card pushing rod fixing seat 3-3. A sun gear 3-5 is sleeved on the rotation axis 3-1, and a toothed ring 1-1 concentric with the rotation axis 3-1 is arranged on the base 1. The planetary gear 3-4 meshes with both the sun gear 3-5 and the toothed ring 1-1. In order to make the transmission more stable, in this embodiment, three planetary gears 3-4 are provided. When the driving device drives the rotation axis 3-1 to rotate, the sun gear 3-5 drives the planetary gear 3-4 to rotate. At the same time, the planetary gear 3-4 rotates around the rotation axis 3-1 inside the toothed ring 1-1. Therefore, the card pushing rod fixing seat 3-3 rotates around the rotation axis 3-1, and the card pushing rod 3-2 can then push the mahjong tiles to move in the misaligned card feeding track 2.

[0034] See Figure 5 , as a preferred solution of this embodiment, the card pushing rod 3-2 includes an upper layer pushing part and a lower layer pushing part, and the lower layer pushing part extends with a protruding part 3-2-1 along the moving direction of the mahjong tiles.

[0035] An entrance and an exit are provided at both ends of the misaligned card feeding track 2. The misaligned card feeding track 2 includes a first card feeding track 2-1 for the lower layer mahjong tiles to slide and a second card feeding track 2-2 for the upper layer mahjong tiles to slide. The second card feeding track 2-2 is longer than the first card feeding track 2-1, and the total moving distance of the upper layer mahjong tiles will be longer than that of the lower layer mahjong tiles. Therefore, when the same stack of tiles reaches the exit, the upper layer mahjong tiles will lag behind the lower layer mahjong tiles.

[0036] Specifically, the misaligned card feeding track 2 is annular. Compared with linear and other types of track grooves, it reduces the space required for pushing the mahjong tiles, which is beneficial to the thinning design of the mahjong machine.

[0037] See Figure 2 and 3, the misaligned card feeding track 2 also includes a track patch 5 with a smooth surface made of wear-resistant material, a plurality of card slots are provided on the base, and a corresponding card hook is provided on the track patch 5. The track patch 5 is clamped with the base 1 for easy assembly and later maintenance and replacement. The track patch 5 includes a bottom patch 5-1, a first side patch 5-2 and a second side patch 5-3. The bottom patch 5-1 is arranged at the bottom of the misaligned card feeding track 2, and two slide rails for supporting mahjong tiles are provided on the bottom patch 5-1, further reducing the contact area between the mahjong tiles and the bottom patch 5-1 and reducing friction. The first side patch 5-2 and the second side patch 5-3 are respectively arranged on the two sides of the misaligned card feeding track 2. The misaligned card feeding track 2 is annular as a whole, and the first side patch 5-2 is set on the inner ring side wall of the misaligned card feeding track, and the second side patch 5-3 is set on the outer ring side wall of the misaligned card feeding track 2. A boss 5-2-1 extends from the first side patch 5-2 toward the second side patch 5-3 in the second offset track 2-2. A groove 5-3-1 is provided on the second side patch 5-3, corresponding to the boss 5-2-1. Due to the placement of the boss 5-2-1, the second track 2-2 is offset toward the outer circle relative to the first track 2-1, causing the movement trajectory of the upper mahjong tiles to deviate slightly toward the outer circle relative to the lower mahjong tiles. This results in the upper mahjong tiles moving along a longer path than the lower mahjong tiles, and in the same mahjong pile, the upper mahjong tiles lag behind the lower mahjong tiles along the direction of travel. The size of the boss 5-2-1 can influence the distance by which the upper mahjong tiles lag behind the lower mahjong tiles. Since the upper mahjong tiles will be slightly ahead of the lower mahjong tiles after the pushing rod 3-2 pushes the mahjong tiles to the lifting mechanism, the card feeding system of this embodiment ensures that the upper mahjong tiles lag behind the lower mahjong tiles when each pile of mahjong tiles reaches the card outlet, thereby solving the problem of misalignment of the upper and lower tiles when the tiles are put into the card feeding mechanism and dispersing the resistance when pushing the tiles up and down.

[0038] The bottom patch 5-1 is provided with a card inlet slope at one end of the card inlet to facilitate the mahjong tiles to enter the dislocated card delivery track 2. The bottom patch 5-1 is provided with a card outlet slope at one end of the card outlet to facilitate the mahjong tiles to enter the card lifting mechanism.

[0039] The tile-lifting mechanism includes a tile receiving block 4, which includes a hinged end 4-1 and a movable end 4-2. Hinged end 4-1 is hinged to base 1, while movable end 4-2 swings around hinged end 4-1. When movable end 4-2 of tile receiving block 4 reaches its lowest point, it is lower than hinged end 4-1. Tiles are positioned obliquely and receive tiles from the staggered tile-feeding mechanism. When movable end 4-2 of tile receiving block 4 reaches its highest point, tile receiving block 4 is flush with the tabletop.

[0040] (Example 2)

[0041] The difference between this embodiment and Embodiment 1 is that in this embodiment, the first side patch 5-2 and the second side patch 5-3 are not provided, and the boss 5-2-1 and the groove 5-3-1 are directly provided on the two side walls of the misaligned card feeding track 2; as a preferred solution, the two side walls of the misaligned card feeding track 2 are made of wear-resistant and smooth-surface materials.

[0042] In the specific embodiments described above, the purpose, technical solutions, and beneficial effects of the present utility model have been further described in detail. It should be understood that the above are only specific embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
