Background

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.

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 that the four-side mahjong wall is placed in a windmill shape in an inclined mode after mahjong tiles reach the table top, the mahjong tile feeding speed is low, gaps, disorder and even toppling of the mahjong tiles fed along the slope after the mahjong tiles are lifted to the table top easily exist, players still need to manually arrange the mahjong tiles generally, and inconvenience caused to the players is not completely solved.

Patent documents CN109381855A disclose a mahjong machine, in which mahjong tiles in four directions of the mahjong machine are respectively inclined to the four edges of a tabletop plate of the mahjong machine and are lifted onto the tabletop of the mahjong machine at one time in a manner of approaching the center of the tabletop plate of the mahjong machine. 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.

Patent documents with publication number CN112023390A and the like disclose a mahjong machine, which comprises a shuffling large disk positioned at the center of a bottom plate of a machine frame, four groups of mahjong picking and carrying systems are arranged around the shuffling large disk, and each mahjong picking and carrying system comprises a mahjong conveying device, a horizontal pushing mahjong loading device and a mahjong pushing device; the horizontal pushing and feeding device comprises a card bearing plate, a card supporting plate and a card pushing plate, wherein the card supporting plate is positioned on the inner side of the card bearing plate, the card pushing plate is positioned on the outer side of the card bearing plate and pushes cards from outside to inside, one end of the card bearing plate, which extends along the length direction, is a card inlet, a card bearing block of the card pushing device is arranged outside the card inlet, and a horizontal pushing and feeding motor drives the card pushing plate to move horizontally and the card supporting plate to lift and feed cards; four mahjong tile feeding ports which are obliquely arranged relative to the side edges of the table top plate are formed in the panel of the mahjong machine, and four tile supporting plates in the four groups of tile picking and carrying systems are matched with the four mahjong tile feeding ports respectively. According to the scheme, the mahjong pieces are independently horizontally pushed in the four directions, and the mahjong piece pushing support frame and the mahjong piece pushing crank thereof are arranged in the space of the corner connecting part of the two mahjong piece conveying devices, so that the mahjong piece supporting plates of the four-direction horizontally-pushing mahjong piece pushing device are driven by respective motors to independently push the mahjong pieces.

However, in the above-mentioned horizontal push type windmill-shaped mahjong machine disclosed in patent documents CN109381855A and CN112023390A, the four-sided tile wall inclined in the windmill shape is located further outside than the four-sided tile wall of the slope type windmill-shaped mahjong machine, and the player still needs to push the mahjong tile wall a little by hand to be suitable for the player to play, which still causes inconvenience to the player. In addition, in the structure of the mahjong machine, the tile outlet direction of the tile feeding device and the tile inlet direction of the tile pushing and loading device are not vertical but form an acute angle, mahjong tiles coming out of the tile feeding device can be pushed into the tile storage groove (on the tile bearing plate) of the tile pushing and loading device after rotating a certain angle, and the tile pushing head in the tile pushing device pushes the tiles linearly along the tile inlet direction (length direction of the tile bearing plate) of the tile pushing and loading device, so that unsmooth tile pushing or tile clamping is easily caused.

Example 1:

for convenience of description, the center of the mahjong machine is taken as the inner side, and the periphery of the mahjong machine is taken as the outer side.

The mahjong machine as shown in fig. 1 to 4 comprises a shuffling large disk 2, a mahjong scraping device and a central lifting device which are positioned in the center of a bottom plate 1 of a machine frame, wherein four groups of mahjong picking and carrying systems are arranged around the shuffling large disk 2, and each mahjong picking and carrying system comprises a mahjong conveying device 5 for picking mahjong from the shuffling large disk one by one and conveying the mahjong, a flat push mahjong-up device 7 for pushing a plurality of arranged mahjong onto the table surface of the mahjong machine at one time and a mahjong pushing device 6 for pushing the mahjong conveyed by the mahjong conveying device 5 into the flat push mahjong-up device 7.

The mahjong tile feeding device 5 generally comprises a mahjong tile feeding shell, a mahjong tile feeding channel for transferring mahjong tiles is arranged in the mahjong tile feeding shell, a mahjong tile sucking wheel is arranged at a mahjong tile inlet of the mahjong tile feeding channel, a conveying belt driven by a mahjong tile feeding motor is arranged in the mahjong tile feeding channel, and the mahjong tile pushing device 6 is arranged outside a mahjong tile outlet of the mahjong tile feeding channel; the two adjacent card sending devices 5 are in transition connection through the connecting walls, the four card sending devices 5 in the four card picking and carrying systems are respectively connected end to end through the four connecting walls to form a card sending enclosure frame, the card sending enclosure frame is arranged around the shuffling large disc 2, the card inlet of each card sending device 5 is positioned on the inner side wall of the card sending enclosure frame, and the card outlet of each card sending device 5 is positioned on the outer side of the card sending enclosure frame.

In this embodiment, the card feeding channel may be a conventional linear channel or an arc-shaped card feeding channel. In order to ensure the conveying reliability of mahjong, the height of the card outlet of the card conveying channel is preferably not lower than that of the card inlet of the card conveying channel. Specific configurations of the card feeding device are conventional, and patent documents such as CN213965119U, CN105363195A, CN105413161A, CN106492454A, CN106669142A, and CN112023390A can be referred to.

The card pushing device 6 comprises a card bearing block 61 for bearing the mahjong sent out by the card sending device 5 and a card pushing head 62 for pushing the mahjong on the card bearing block 61 to the flat card pushing device 7, and the card bearing block 61 and the card pushing head 62 are driven by a card pushing motor 68. As a specific structure of the card pushing device, a conventional technique can be adopted, and patent documents with publication numbers CN201906453U, CN201949619U, CN103861280A, CN112023390A, and CN204699375U can be referred to. However, in the structure of the horizontal pushing and tile feeding windmill-shaped mahjong machine, the tile outlet direction of the tile feeding device and the tile inlet direction of the tile feeding device are not perpendicular but form an acute angle, mahjong tiles discharged from the tile feeding device can be pushed into a tile storage groove (on the tile bearing plate) of the horizontal pushing and tile feeding device after rotating a certain angle, so that the tile pushing head in the tile pushing device linearly moves along the tile inlet direction (length direction of the tile bearing plate) of the horizontal pushing and tile feeding device to push tiles, which easily causes unsmooth tile pushing or tile blocking.

Therefore, the present embodiment preferably employs a swing type card pushing head for the card pushing device. The tile pushing device shown in fig. 5 and 6 comprises a tile pushing shell, a tile pushing motor 68 is mounted on the tile pushing shell, a tile pushing transmission mechanism is arranged in the tile pushing shell, a tile bearing block 61 and a tile pushing head 62 are arranged outside the tile pushing shell, the tile pushing motor 68 drives the tile bearing block 61 to lift up and down through the tile pushing transmission mechanism to stack tiles, the tile pushing motor 68 drives the tile pushing head 62 to swing back and forth and horizontally around a specific axis through the tile pushing transmission mechanism to push the stacked tiles out of the tile bearing block 61, and the specific axis is vertically arranged on the outer side of the tile bearing block 61 and arranged along the tile discharging direction of the tile feeding device 5. Therefore, the swing type tile pushing head is more suitable for the layout of the tile feeding device and the tile horizontally pushing device of the horizontally pushing and tile feeding windmill-shaped mahjong machine, and tiles are smoothly and stably pushed without being blocked.

Further preferably, the card pushing head 62 has at least two card pushing positions: when the pushing head 62 starts to push the mahjong tiles on the tile bearing block 61, the first pushing part contacts the mahjong tiles firstly; when the pushing head 62 pushes the mahjong tiles onto the tile bearing plate 72, the second pushing part contacts the mahjong tiles, or the first pushing part and the second pushing part contact the mahjong tiles simultaneously.

In other embodiments, the horizontal pushing and card-putting device 7 having the lifting and lowering card-supporting plate 72 may also be used for putting cards in stages, for example, three layers of mahjong cards are stored on the card-supporting plate 72, when putting cards, the card-supporting plate 71 descends to the bottom, the card-pushing plate 73 pushes the top layer of mahjong cards onto the card-supporting plate 71, the card-supporting plate 71 ascends to lift the mahjong cards to the table top, after the player takes the mahjong cards away, the card-supporting plate 71 descends again, the card-pushing plate 73 pushes the remaining two layers of mahjong cards onto the card-supporting plate 71, and the card-supporting plate 71 ascends to push the mahjong cards to the table top.

In the prior art, in the horizontal push type windmill-shaped mahjong machine disclosed in patent documents CN209645828U, CN109381855A, CN112023390A and the like, the four-side tile wall inclined in the windmill shape is located further outside than the four-side tile wall of the slope type windmill-shaped mahjong machine, and generally, a player needs to manually push the mahjong tile wall into a little to be suitable for the player to play, which still causes inconvenience to the player. It is therefore preferable to push the mahjong wall inward, as much as the mahjong wall of the slope-type windmill mahjong machine, so that the player does not need to push the mahjong again.

In one embodiment, the tile supporting plate 71 and the driving mechanism thereof adopt the prior art structure, the tile supporting plate 71 extends and widens inwards, the width of the tile supporting plate 71 is larger than that of the mahjong tile wall, namely, a supporting area for placing the mahjong tile wall and a transition area which is positioned outside the supporting area and is not used for placing the mahjong tile wall are formed on the tile supporting plate 71, and the transition area is only connected with the tile supporting plate 72 when the tile pushing plate 73 pushes tiles and is used for pushing the mahjong tile wall to pass through. However, such a structure has several problems: firstly, the mahjong machine is influenced by arranging the wide mahjong-feeding ports and the mahjong-supporting plates on the table top plate, secondly, the four wide mahjong-feeding ports can cause the hollow area of the table top plate to be large, the strength is low, the mahjong-playing machine is easy to deform, then, in order to avoid that the lifting assembly (comprising the guide rod, the mahjong-feeding crank, the mahjong-feeding cam and the like) at the bottom of the mahjong-supporting plate 71 excessively occupies a shuffling space, the supporting position of the lifting assembly on the mahjong-supporting plate 71 is generally outside the mahjong wall, so that the mahjong-supporting plate is unbalanced in supporting and not stable enough, the mahjong-supporting plate is easy to loosen, and the service life of the mahjong machine is influenced. Of course, the latter two problems can be solved by improving materials, adding reinforcements or reinforcing structures, and therefore, the embodiment can be used in occasions with low requirements on the appearance of the mahjong machine.

In another embodiment, the width of the card supporting plate 71 is unchanged, the position of the card supporting plate 71 is moved inwards, when the card supporting plate 71 is lowered to the bottom, a transition plate 74 is arranged between the card supporting plate 71 and the card supporting plate 72, so that the card supporting plate 72 and the card supporting plate 71 are connected and a mahjong wall can be pushed to pass through when the card pushing plate 73 pushes cards. Wherein, the transition plate 74 is arranged on the card supporting plate 71, the card supporting plate 72 or the card feeding seat 70. The transition plate 74 may be fixed to or integrally formed with the deck plate 72 or the deck shoe 70.

Preferably, in this embodiment, as shown in figures 24, 25, 34, 37, 40, 43, 47 and 48, the transition plate 74 is hinged to the inside of the card support plate 72 or the card shoe 70 so that the transition plate 74 can be erected or laid flat. Thus, when the card is stored by pushing the card-loading device 7 horizontally, as shown in fig. 25, the transition plate 74 is in a standing state so as to serve as an inner side blocking wall of the card-supporting plate 72 to prevent the mahjong from falling off the card-supporting plate 72; when the tile pushing device 7 pushes the tiles, as shown in fig. 26 and 27, the tile supporting plate 71 descends, the transition plate 74 is laid flat, and the tile pushing plate 73 pushes the mahjong tile wall inwards; as shown in fig. 28 and 29, the transition plate 74 is laid flat to form a transition area through which the mahjong wall can be pushed; as shown in fig. 30 and 31, the mahjong tile pushing plate 73 pushes the mahjong tile wall to the tile supporting plate 71 to be reset, and the transition plate 74 is erected to be reset; as shown in fig. 32 and 33, the support plate 71 raises the wall of the tiles up the mahjong table. Simple structure, simple to operate, the function is reliable.

It is further preferred that the transition plate 74 impart a tendency for the transition plate 74 to rise upwardly through the elastic member. Therefore, the transition plate is in a standing state under the state of not being subjected to external force, and the push plate is pressed and laid flat, so that the interference between the transition plate 74 and the card supporting plate 71 can be avoided, and an additional supporting piece is not required to be arranged for supporting the transition plate. The elastic member may be a tension spring, a torsion spring, or an elastic push rod, but is preferably a torsion spring sleeved on the hinge shaft of the transition plate 74.

Preferably, in this embodiment, the transition plate 74 is provided with a spring to give the transition plate 74 a tendency to lay flat. The transition plate is in a flat state without external force, so that the load of the motor for pushing the mahjong tiles is reduced, the collision noise of the mahjong tiles is reduced, and the transition plate is supported by an additional supporting structure or a supporting piece. The elastic member may be a tension spring, a torsion spring, or an elastic push rod, but is preferably a torsion spring sleeved on the hinge shaft of the transition plate 74.

Thus, the first transition support 711 can not only support the transition plate 74, but also form a support with the bottom of the table top plate 4, thereby improving the stability of the card support plate, avoiding the influence of looseness on the service life, and having simple and reliable structure and low cost. The first transition supporting member 711 may be a whole plate, or may be formed by a plurality of small supporting plates, or may be an independent component fixedly connected to the card supporting plate 71, or may be integrally formed with the card supporting plate 71. In the present embodiment, the first transition supporting member 711 is preferably a unitary plate integrally formed with the card supporting plate 71, so that the support is more secure and reliable. More preferably, the lifting guide member (guide rod or guide sleeve) of the tile supporting plate 71 is arranged on the first transition support member 711, and the tile feeding cam 713 of the tile supporting plate 71 is arranged at the bottom of the tile supporting plate 71, so that the tile supporting plate 71 and a mahjong tile wall thereon can be supported more uniformly and stably, further the tile supporting plate 71 is prevented from loosening, and the service life is prolonged.
