A mahjong machine and its tile picking and transporting system

Abstract

The present invention discloses a card-picking and transporting system, which includes a card-sending device for picking up mahjong tiles one by one from a shuffling tray and sending them out, a flat pushing and card-placing device and a ramp card-placing mechanism for sending the arranged mahjong tiles onto the mahjong tabletop, and a card-pushing head for pushing the mahjong tiles to the flat pushing and card-placing device and the ramp card-placing mechanism respectively; wherein, along the direction of sending out mahjong tiles, a first card-pushing position and a second card-pushing position are sequentially arranged on the outer edge of the card outlet of the card-sending device, the card-pushing head pushes a single mahjong tile at the first card-pushing position to the flat pushing and card-placing device, and the card-pushing head pushes a single mahjong tile at the second card-pushing position to the ramp card-placing mechanism; in the process of transporting mahjong tiles in this technical solution, the mahjong tiles are always transported in a single layer, which can significantly shorten the vertical distance for the mahjong tiles to rise to the mahjong tabletop. That is, for the ramp card-placing mechanism, the slope of its ramp is significantly reduced, thereby making the card-placing process smoother and more stable.

Description

Technical Field

[0001] The present invention relates to the technical field of mahjong machine manufacturing, and particularly to an eight-port mahjong machine and its card-picking and transporting system. Background Art

[0002] Currently, fully automatic mahjong machines can integrate functions such as shuffling and dice-throwing, providing a lot of convenience for people to play cards. However, currently, most fully automatic mahjong machines are basically only provided with four outlets, and then the mahjong is conveyed from the four outlets to the mahjong table. During card-playing, manual pushing, cutting, and stacking of cards are still required, which is not only rather troublesome to operate but also may result in incorrect card-cutting, and thus the cards have to be reshuffled.

[0003] To solve this problem, a Chinese invention patent with the patent number CN200920118048.7 discloses an automatic mahjong machine, which includes a mahjong machine tabletop and a main unit arranged below the mahjong machine tabletop. An inner lattice board is arranged inside the main unit, and outer lattice boards are arranged on the outer sides of the inner lattice board. The 4 outer lattice boards are connected into an annular track for carrying mahjong tiles through 4 arc transition sections. Above the annular track, there is an annular pushing device for pushing mahjong tiles. Below the card-pushing head, there is a slide rail, and the card-pushing head is driven by a motor to slide between the inner pushing port and the outer pushing port. On the mahjong machine tabletop directly above the 4 outer lattice boards, there are all tipping devices for guiding the mahjong tiles on the annular track to the mahjong machine tabletop. The automatic mahjong machine provided by the present invention enables each of the thirteen cards to be grabbed by the game participants on each of the four outer sides, allowing the game participants to obtain a more convenient, fast, and comfortable gaming experience.

[0004] The card-raising principle of this automatic mahjong machine is as follows: Initially, the card-pushing head of the card-pushing head is at the outer card-pushing port and pushes cards onto the outer lattice board. When 13 cards are pushed, the control system issues an instruction, and the card-pushing head drives the card-pushing head to move to the inner card-pushing port, and then the card-pushing head starts to push cards. After the card-pushing head has pushed a certain number of stacks (varying according to the total number of stacks in card-playing), the motor of the flat-pushing component rotates, driving the guide plate to drop, and then the second layer of cards is pushed. When 13 cards are pushed on each of the 4 outer lattice boards and all the card-pushing heads have moved to the inner card-pushing port, the control system issues a signal, and the wire rope motor starts to rotate, driving the cards to move on the annular track and reach the position waiting for card-raising. When the cards on 1 inner lattice board are stacked, the conveying motor rotates in reverse to pour the remaining cards in the conveying device back into the large tray and send them to the card-raising ports of other conveying devices until the cards on all 4 inner lattice boards are stacked.

[0005] The disadvantages of this automatic mahjong machine are as follows:

[0006] 1). There are an outer pushing card opening and an inner pushing card opening in the conveying channel. The mahjong tiles first pass through the inner pushing card opening and then through the outer pushing card opening. Therefore, when the pushing head is at the inner pushing card opening, the mahjong tiles may be left behind and reach the outer pushing card opening, causing the mahjong machine to jam.

[0007] 2). The pushing head needs to be driven by another driving device such as a motor to move from the outer pushing card opening to the inner pushing card opening and from the inner pushing card opening to the outer pushing card opening, resulting in high costs.

[0008] The patent application document with the publication number CN107519637A discloses a mahjong machine and its card-dealing method. The mahjong machine includes four sets of card-picking and transporting systems arranged around the shuffling tray. The card-picking and transporting system includes a card-sending device for picking up mahjong tiles one by one from the shuffling tray and sending them out, a card-stacking device for stacking two mahjong tiles into a stack, a card-pushing device for pushing the mahjong tiles into the card storage slot, and a ramp card-dealing device for sending multiple stacks of arranged mahjong tiles onto the mahjong machine table along a ramp. The ramp card-dealing device includes a card-dealing component and a card-lifting component. The card-dealing component includes a card storage slot, and the card storage slot is bent in a large-angle arc, increasing the storage quantity of mahjong tiles in the card storage slot. The card-dealing component and the card-lifting component in the same set of card-picking and transporting systems are directly adjacent. The above-mentioned mahjong machine can implement the method of card-dealing in stages. When storing mahjong tiles, the card-sending device picks up the mahjong tiles and the card-pushing device pushes them into the card storage slot. When the mahjong machine receives the first card-dealing signal, the card-lifting tray of the card-lifting device descends, and the card-dealing pushing head first pushes a part of the mahjong tiles (usually six and a half stacks or thirteen mahjong tiles) in the card storage slot onto the card-lifting tray. The card-lifting tray rises to deal these mahjong tiles onto the table for the player to take away the mahjong tiles on the table. After the mahjong machine receives the second card-dealing signal, the card-lifting tray descends again, and the card-dealing pushing head pushes the remaining mahjong tiles in the card storage slot onto the card-lifting tray. The card-lifting tray rises to deal the mahjong tiles onto the table. By adopting this scheme of card-dealing in two stages in a phased manner, the function of an eight-port mahjong machine can be realized using the structure of an existing four-port mahjong machine. However, since the card-dealing pushing head occupies the position of one stack of tiles in the card storage slot during the process of dealing cards to the card-lifting device, the length of the card storage slot required for 17 stacks of tiles is 18 - 19 stacks of tiles. When playing larger-sized games with this type of mahjong machine, the required track length of the mahjong machine is relatively long, and it cannot be achieved with mahjong machines of the existing model size. Therefore, it is necessary to minimize the length of the card storage slot of the mahjong machine.

[0009] The utility model patent with the publication number CN108635827A discloses a card - feeding structure of a three - layer mahjong machine, which includes an annular single - layer card track and an annular double - layer card track installed overlapping up and down. A motor base is installed on the single - layer card track. The motor base is provided with a second motor through a gear, and the motor base is provided with a first motor through a rotating shaft. The passive shaft on the motor base is connected with a single - layer card turntable through a bearing. The teeth of the single - layer card turntable are engaged with the gear. A single - layer card pusher is arranged on the single - layer card turntable. A card - adjusting ring and a double - layer card pusher placed inside the card - adjusting ring are installed on the double - layer card track. After three - layer cards enter the card track, the second motor drives the gear to drive the single - layer card turntable to rotate, and the single - layer card pusher on the single - layer card turntable pushes the cards on the single - layer card track to the mahjong machine tabletop. After three - layer cards enter the card track, the first motor drives the rotating shaft to drive the double - layer card pusher to rotate, and pushes the cards on the double - layer card track to the mahjong machine tabletop. For the mahjong machine with the above structure, three mahjong cards are stacked into a stack. The stack of mahjong cards is divided into a single layer (one card) and a double layer (two cards stacked) and are respectively sent into the single - layer card track and the double - layer card track and then sent to the mahjong machine tabletop. Such a setting can effectively shorten the required track length of the mahjong machine. However, the occupied height of the card - feeding structure of the above mahjong machine is relatively large, and the overall height of the mahjong machine using this structure is relatively large. Especially when playing with larger mahjong cards, it cannot be realized by the existing mahjong machines of the current model size. Moreover, when dividing a stack of mahjong cards into a single layer (one card) and a double layer (two cards stacked) and respectively sending them into the single - layer card track and the double - layer card track, the required precision at the track boundary is extremely high, and even a slight deviation will cause the mahjong machine to jam. On the other hand, two motors are respectively used to directly or indirectly drive two card - pushing heads to push the mahjong cards in the single - layer card track and the double - layer card track, which increases the structural complexity and control complexity of the mahjong machine, and increases the production cost of the mahjong machine. Summary of the Invention

[0010] The purpose of the present invention is to provide a mahjong machine and its card - picking and transporting system according to the deficiencies of the prior art. The card - picking and transporting system adopts the method of single - layer card transportation and uses double card - pushing heads to respectively transport mahjong cards to the outer card - feeding track and the inner card - feeding track, avoiding the easy jamming situation when dividing a stack of mahjong cards into a single layer (one card) and a double layer (two cards stacked) and respectively sending them into the single - layer card track and the double - layer card track, reducing the structural complexity and control complexity of the mahjong machine, and reducing the production cost of the mahjong machine.

[0011] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0012] A card-picking and transporting system includes a card-feeding device for picking up mahjong tiles one by one from a shuffling tray and sending them out, a flat-top card-playing device and a ramp card-playing mechanism for sending the arranged mahjong tiles onto the mahjong tabletop, and a card-pushing head for pushing the mahjong tiles to the flat-top card-playing device and the ramp card-playing mechanism respectively; wherein, along the direction of sending out mahjong tiles, a first card-pushing position and a second card-pushing position are sequentially arranged on the outer edge of the card outlet of the card-feeding device, the card-pushing head includes a first card-pushing head and a second card-pushing head, a blocking block that can move in and out is further arranged between the first card-pushing position and the second card-pushing position, the card inlet of the flat-top card-playing device and the first card-pushing head are respectively located on opposite sides of the first card-pushing position, and the card inlet of the ramp card-playing mechanism and the second card-pushing head are respectively located on opposite sides of the second card-pushing position; when the blocking block moves into the space between the first card-pushing position and the second card-pushing position, the blocking block prevents the mahjong tiles from entering the second card-pushing position, and the first card-pushing head pushes the single mahjong tile at the first card-pushing position into the card inlet of the flat-top card-playing device; when the blocking block moves out of the space between the first card-pushing position and the second card-pushing position, the mahjong tiles enter the second card-pushing position, and the second card-pushing head pushes the single mahjong tile at the second card-pushing position into the card inlet of the ramp card-playing mechanism.

[0013] Preferably, the card-pushing head further includes a card-pushing motor. When the card-pushing motor rotates forward, the blocking block is located between the first card-pushing position and the second card-pushing position, and the first card-pushing head pushes the single mahjong tile at the first card-pushing position into the card inlet of the flat-top card-playing device; when the card-pushing motor rotates backward, the blocking block is no longer located between the first card-pushing position and the second card-pushing position, and the second card-pushing head pushes the single mahjong tile at the second card-pushing position into the card inlet of the ramp card-playing mechanism.

[0014] Preferably, a camshaft in transmission cooperation with the card-pushing motor, a one-way bearing A, a first curve wheel and a second curve wheel sleeved on the camshaft are arranged on the head box. The inner surface of the first curve wheel is in transmission cooperation with the outer surface of the one-way bearing A, the outer surface of the first curve wheel is in transmission connection with the first card-pushing head and the blocking block, the outer surface of the second curve wheel is in transmission connection with the second card-pushing head and the blocking block. When the card-pushing motor rotates forward, it can drive the first curve wheel to rotate forward to drive the first card-pushing head to push the card and make the blocking block located between the first card-pushing position and the second card-pushing position. When the card-pushing motor rotates backward, it drives the second curve wheel to rotate backward to drive the second card-pushing head to push the card and make the blocking block no longer located between the first card-pushing position and the second card-pushing position.

[0015] Preferably, the card blocking block includes a second card blocking portion and a first card blocking portion. The second card blocking portion moves in and out between the first card pushing position of the card feeding device and the card inlet of the horizontal card placing device to block or pass through. The first card blocking portion moves in and out between the first card pushing position and the second card pushing position to block or pass through. The second card blocking portion and the first card blocking portion are fixedly connected or integrally formed. The conveyor belt of the card feeding device extends to the first card blocking portion of the card blocking block between the first card pushing position and the second card pushing position. When the first card blocking portion blocks between the first card pushing position and the second card pushing position, the second card blocking portion moves out between the first card pushing position of the card feeding device and the card inlet of the horizontal card placing device, so that the first card pushing head can push a single mahjong tile located at the first card pushing position into the card inlet of the horizontal card placing device. When the first card blocking portion moves out between the first card pushing position and the second card pushing position, the second card blocking portion enters between the first card pushing position of the card feeding device and the card inlet of the horizontal card placing device to prevent the mahjong tiles from entering the card inlet of the horizontal card placing device.

[0016] Preferably, when the horizontal card placing device feeds cards, the initial position of the card blocking block is between the first card pushing position and the second card pushing position. The card pushing motor rotates forward to drive the first curve wheel to rotate forward, and the first card pushing head implements card pushing. The first card pushing head pushes a single mahjong tile from the first card pushing position into the horizontal card placing device. After the card pushing motor rotates forward one circle, the first card pushing head returns to its original position and waits for the next card pushing. This action is repeated until the horizontal card placing device is full of mahjong tiles. During this card pushing process, the second card pushing head makes an empty push or remains stationary.

[0017] After the horizontal card placing device is full of cards, the card pushing motor rotates in reverse to drive the second curve wheel to rotate, thereby causing the card blocking block to move out between the first card pushing position and the second card pushing position. During this process, the first card pushing head remains stationary and the second card pushing head makes an empty push.

[0018] When the ramp card placing mechanism feeds cards, the card pushing motor rotates in reverse to drive the second curve wheel to rotate, causing the second card pushing head to implement card pushing. The second card pushing head pushes a single mahjong tile from the second card pushing position into the ramp card placing mechanism. After the card pushing motor rotates in reverse one circle, the second card pushing head returns to its original position and waits for the next card pushing. This action is repeated until the ramp card placing mechanism is full of mahjong tiles. During this card pushing process, the first card pushing head remains stationary.

[0019] After the ramp card placing mechanism is full of cards, the card pushing motor rotates forward to drive the first curve wheel to rotate, thereby causing the card blocking block to move into the position between the first card pushing position and the second card pushing position to wait for the next card placing.

[0020] Preferably, the ramp card - feeding mechanism includes a card - feeding pushing head and a card - feeding support. The card - feeding support is provided with a first card - feeding guide rail. The first card - feeding guide rail arranges and stores a single layer of mahjong tiles in the width direction of the mahjong tiles. A first flap is provided at the outgoing card - outlet. One side of the first flap is hinged to the mahjong machine tabletop or the card - feeding support. The section of the first card - feeding guide rail close to the outgoing card - outlet is an inclined section extending upward to connect with the mahjong machine tabletop. The card - feeding pushing head moves to push the mahjong tiles forward along the first card - feeding guide rail and lift the other side of the first flap, and then pushes the mahjong tiles onto the mahjong machine tabletop.

[0021] Preferably, the ramp card - feeding mechanism includes a card - feeding pushing head and a card - feeding support. The card - feeding support is provided with a second card - feeding guide rail. The second card - feeding guide rail arranges and stores a single layer of mahjong tiles in the width direction of the mahjong tiles. A second flap is provided at the outgoing card - outlet. The second flap has two staying positions: flush with the mahjong machine tabletop and docking with the second card - feeding guide rail. When feeding cards, the second flap drops to dock with the second card - feeding guide rail. The card - feeding pushing head pushes the mahjong tiles on the second card - feeding guide rail onto the second flap, and then the second flap flips up to be flush with the mahjong machine tabletop.

[0022] Preferably, the flat - pushing card - feeding mechanism includes a lattice board, a first card - feeding motor, a card - supporting plate, a card - pushing mechanism, and a lifting mechanism installed on the lattice board. When the first card - feeding motor rotates, the card - supporting plate is driven by the lifting mechanism to rise to be flush with the mahjong machine tabletop, and then the mahjong tiles on the card - supporting plate are pushed out onto the mahjong machine tabletop by the card - pushing mechanism, and then the card - supporting plate descends to reset.

[0023] Preferably, the flat - pushing card - feeding mechanism includes a lattice board, a first card - feeding motor, a card - supporting plate, a card - pushing mechanism, and a lifting mechanism installed on the lattice board. A cover plate flush with the mahjong machine tabletop is provided on the mahjong machine tabletop. The lifting mechanism drives the cover plate to lift and lower. When the first card - feeding motor rotates, the cover plate is driven by the lifting mechanism to descend to a height matching the card - supporting plate, and then the mahjong tiles on the card - supporting plate are pushed out onto the cover plate by the card - pushing mechanism, and then the cover plate rises to the tabletop.

[0024] A mahjong machine includes the card - picking and transporting system as described above.

[0025] The technical effects of the present invention are as follows:

[0026] 1), During the process of transporting mahjong tiles by the entire mahjong machine, it always transports the mahjong tiles in a single layer. This can significantly shorten the vertical distance for the mahjong tiles to rise to the mahjong machine tabletop. That is, for the ramp tile feeding mechanism, the ramp slope is significantly reduced, making the tile feeding process smoother and more stable. For the tile pushing head, it no longer needs to stack the mahjong tiles, making the tile pushing mechanism simple in structure and avoiding problems such as easy tile flipping during stacking. For the entire mahjong machine, it enables the four tile picking and transporting systems to be arranged more compactly, thereby reducing the volume of the entire mahjong machine.

[0027] 2), In the present invention, there are four inner tile outlets and four outer tile outlets on the mahjong machine tabletop. The four inner tile outlets are rectangular and parallel to the edge of the mahjong machine tabletop. This way, the space occupied by the shuffling tray is increased as much as possible, enabling the shuffling tray to wash larger tiles, which is more in line with the playing habits of players.

[0028] 3), The flat pushing tile feeding device first raises the mahjong tiles to the mahjong machine tabletop by the tile supporting plate and then pushes the mahjong tiles out. That is, the space occupied by pushing the mahjong tiles out is transferred to the mahjong machine tabletop of the mahjong machine, making the internal space of the mahjong machine more abundant, and thus the volume of the mahjong machine can be reduced.

[0029] 4), In the ramp tile feeding mechanism, the tile feeding process of the mahjong tiles is smooth, so that the mahjong tiles will not get stuck or jam due to too large a ramp slope.

[0030] 5), Adopting the single-layer tile transportation method and using double tile pushing heads to transport the mahjong tiles to the outer tile feeding track and the inner tile feeding track respectively, it avoids the situation of easy jamming when dividing a stack of mahjong tiles into a single layer (one tile) and a double layer (two tiles stacked) and sending them into the single-layer tile track and the double-layer tile track respectively, reduces the structural complexity and control complexity of the mahjong machine, and reduces the production cost of the mahjong machine.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0075] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "over", and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "beneath", and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0076] In the present invention, the inside of the mahjong machine is centered around the center of the mahjong machine, and the outside is around the perimeter of the mahjong machine.

[0077] In the present invention, the forward rotation and reverse rotation of a single motor only represent the opposite rotation directions of the single motor itself. That is, when one motor rotates forward and the other motor rotates in reverse, the rotation directions of the two motors can be the same or different.

[0078] Embodiment 1:

[0079] As Figures 1 - 3 shown, a mahjong machine includes a bottom plate 1, a mahjong machine tabletop 2, a shuffling tray 3 located in the center and its driving mechanism, and four groups of card-picking and transporting systems around the four sides of the shuffling tray 3. The card-picking and transporting system includes a card-sending device 4 for picking up mahjong tiles 10 one by one from the shuffling tray 3 and sending them out, a flat-pushing card-lifting device 5 and a ramp card-lifting mechanism 6 for sending the arranged mahjong tiles 10 onto the mahjong machine tabletop 2, and a card-pushing head 7 for pushing the mahjong tiles 10 to the flat-pushing card-lifting device 5 and the ramp card-lifting mechanism 6 respectively. Among them, the four flat-pushing card-lifting devices 5 enclose a rectangular shape parallel to the edge of the tabletop, the four ramp card-lifting mechanisms 6 enclose a rectangular shape parallel to the edge of the tabletop, and the ramp card-lifting mechanism 6 is located outside the flat-pushing card-lifting device 5.

[0080] The card-pushing head 7 can push a single mahjong tile 10 onto the flat-pushing card-lifting device 5 until the first layer of mahjong tiles 10 on the flat-pushing card-lifting device 5 is full. Then, the card-pushing head 7 pushes the second layer of mahjong tiles 10 onto the first layer of mahjong tiles 10, and then the flat-pushing card-lifting device 5 pushes the cards out and raises them to the mahjong machine tabletop 2.

[0081] The pushing head 7 of the tile-pushing mechanism can also move a single mahjong tile 10 on the ramp tile-loading mechanism 6 until the specified number of tiles is reached, and then the ramp tile-loading mechanism 6 pushes the tiles out and raises them to the mahjong tabletop 2 of the mahjong machine.

[0082] In this way, during the process of transporting the mahjong tiles 10, the entire mahjong machine always transports the mahjong tiles 10 in a single layer. This can significantly shorten the vertical distance for the mahjong tiles 10 to rise to the mahjong tabletop 2. That is, for the ramp tile-loading mechanism 6, the slope of its ramp is significantly reduced, and thus the tile-loading process becomes smoother and more stable. For the pushing head 7 of the tile-pushing mechanism, it no longer needs to perform the tile-stacking action on the mahjong tiles 10, making the structure of the tile-pushing mechanism simple and avoiding problems such as the mahjong tiles 10 being easily overturned during tile stacking. For the entire mahjong machine, it can make the four tile-picking and transporting systems arranged more compactly, thereby reducing the volume of the entire mahjong machine.

[0083] As Figures 4 - 5 shown, the mahjong tabletop 2 of the mahjong machine is provided with four inner tile outlets 25 and four outer tile outlets 26. The four inner tile outlets 25 are rectangular openings and are parallel to the edge of the mahjong tabletop 2. The four outer tile outlets 26 are located outside the inner tile outlets 25. The four outer tile outlets 26 are respectively located at the four corners of the mahjong tabletop 2 or near the four corners. The flat-pushing tile-loading device 5 sends two layers of mahjong tiles 10 to the mahjong tabletop 2 through the four inner tile outlets 25, and the ramp tile-loading mechanism 6 sends single-layer tiles to the mahjong tabletop 2 through the four outer tile outlets 26.

[0084] In the embodiment of the present application, the distribution of the four inner tile outlets 25 has the following differences compared with that of the existing similar four-outlet mahjong machines: For the four-outlet mahjong machines, all the mahjong tiles 10 are transported to the mahjong tabletop 2 through the four tile outlets. Therefore, the tile outlets of the four-outlet mahjong machines need to accommodate a complete stack of mahjong tiles 10. Moreover, currently, the head stacking and pushing components of the four-outlet machines are integrated into one body, which relatively occupies more space, resulting in the minimum length of the tile-supporting board being not less than 540 mm. However, in the eight-outlet mahjong machine of the embodiment of the present application, the inner tile outlets 25 only need to accommodate the remaining stack of mahjong tiles 10 after the player grabs 12 - 13 tiles at most. In this way, the maximum length of the supporting board can not exceed 458 mm. Such a setting can make the distance between the inner and outer openings farther and also leave space for the head tile-pushing component. In the eight-outlet mahjong machine of the embodiment of the present application, to ensure that the overall performance of the mahjong machine is in a better state, the interval distance between two opposite inner tile outlets 25 should be controlled within the range of 400 mm - 540 mm, and the width of the inner tile outlets 25 is controlled within the range of not exceeding 458 mm.

[0085] As Figure 14The shown tile-pushing head 7 includes a head box 71, at least one tile-pushing motor 72, a first tile-pushing head 73, a second tile-pushing head 74, a tile-blocking piece 75, a first curve wheel 76 and a second curve wheel 77. The at least one tile-pushing motor 72 is installed on the head box 71; the first tile-pushing head 73 is installed on the head box 71 and is driven by the tile-pushing motor 72 to translate and slide relative to the head box 71; the second tile-pushing head 74 is installed on the head box 71 and is driven by the tile-pushing motor 72 to translate and slide relative to the head box 71; the tile-blocking piece 75 is installed on the head box 71 and is driven by the tile-pushing motor 72 to move up and down relative to the head box 71; and a first tile-pushing position 421 and a second tile-pushing position 422 are arranged before and after in the conveying direction of the mahjong tiles 10. The tile-blocking piece 75 is arranged between the first tile-pushing position 421 and the second tile-pushing position 422 and can move up and down to block the mahjong tiles 10 and allow the mahjong tiles 10 to pass through. The first tile-pushing head 73 is located on one side of the first tile-pushing position 421 and translates and slides in and out of the first tile-pushing position 421 to push the tiles. The second tile-pushing head 74 is located on one side of the second tile-pushing position 422 and translates and slides in and out of the second tile-pushing position 422 to push the tiles. Further preferably, the card-feeding port of the flat tile-feeding device 5 and the first tile-pushing head 73 are respectively located on opposite sides of the first tile-pushing position 421, and the card-feeding port of the ramp tile-feeding mechanism 6 and the second tile-pushing head 74 are respectively located on opposite sides of the second tile-pushing position 422; when the tile-blocking piece 75 moves into the space between the first tile-pushing position 421 and the second tile-pushing position 422, the tile-blocking piece 75 prevents the mahjong tiles 10 from entering the second tile-pushing position 422, and the first tile-pushing head 73 pushes the single mahjong tile 10 located at the first tile-pushing position 421 into the card-feeding port of the flat tile-feeding device 5; when the tile-blocking piece 75 moves out of the space between the first tile-pushing position 421 and the second tile-pushing position 422, the mahjong tiles 10 enter the second tile-pushing position 422, and the second tile-pushing head 74 pushes the single mahjong tile 10 located at the second tile-pushing position 422 into the card-feeding port of the ramp tile-feeding mechanism 6.

[0086] Among them, the first tile-pushing position 421 refers to the position space outside the card-playing port of the card-feeding device 4 for the first tile-pushing head 73 to push the tiles. The second tile-pushing position 422 refers to the position space outside the first tile-pushing position 421 for the second tile-pushing head 74 to push the tiles. The tile-blocking piece 75 moving into the space between the first tile-pushing position 421 and the second tile-pushing position 422 means that the tile-blocking piece 75 is within the space height of the first tile-pushing position 421 and the second tile-pushing position 422. The tile-blocking piece 75 moving out of the space between the first tile-pushing position 421 and the second tile-pushing position 422 means that the tile-blocking piece 75 is not within the space height of the first tile-pushing position 421 and the second tile-pushing position 422. In this embodiment, the conveyor belt of the card-feeding device 4 extends to the lower part of the first tile-pushing position 421 to form a first tile-bearing platform for storing the mahjong tiles 10.

[0087] Specifically, a first curve wheel 76, a second curve wheel 77 and a first mounting seat 78 are provided on the machine head box 71. The first mounting seat 78 is slidably connected to the machine head box 71 up and down. The blocking card block 75 is fixed on the first mounting seat 78. The first mounting seat 78 is in driving connection with the first curve wheel 76. The first card pushing head 73 is slidably connected to the first mounting seat 78 in translation. The second card pushing head 74 is slidably connected to the machine head box 71 in translation. The first card pushing head 73 and the second card pushing head 74 are respectively in driving connection with the second curve wheel 77. The first curve wheel 76 and the second curve wheel 77 are respectively in driving connection with the card pushing motor 72. The card pushing motor 72 drives the first card pushing head 73 and the blocking card block 75 to lift together through the first curve wheel 76. The card pushing motor 72 drives the first card pushing head 73 and / or the second card pushing head 74 to push the cards through the second curve wheel 77. Further preferably, a seventh connecting block 782 is provided at the bottom of the first mounting seat 78. A fourth rolling bearing 781 is provided at the bottom of the seventh connecting block 782. A plurality of guide posts are further provided on the upper surface of the machine head box 71. The first mounting seat 78 is liftably mounted on the guide posts. When the first curve wheel 76 rotates, it can lift the fourth rolling bearing 781, so that the first mounting seat 78 rises stably through the guide posts, thereby causing the first card pushing head 73 and the blocking card block 75 to rise.

[0088] Specifically, when the blocking card block 75 moves into the space between the first card pushing position 421 and the second card pushing position 422, the blocking card block 75 prevents the mahjong tiles 10 from entering the second card pushing position 422, and the first card pushing head 73 pushes the single mahjong tile 10 located at the first card pushing position 421. When the blocking card block 75 moves out of the space between the first card pushing position 421 and the second card pushing position 422, the mahjong tiles 10 enter the second card pushing position 422, and the second card pushing head 74 pushes the single mahjong tile 10 located at the second card pushing position 422, and the first card pushing head 73 does not push the single mahjong tile 10 passing through the first card pushing position 421.

[0089] Specifically, a first connecting block 70 is provided inside the machine head box 71. The lower part of the first connecting block 70 is hinged to the machine head box 71. The upper part of the first connecting block 70 is movably matched with the first card pushing head 73 and / or the second card pushing head 74. The first connecting block 70 is driven by the second curve wheel 77 to swing, so as to push the first card pushing head 73 and / or the second card pushing head 74 to push the cards.

[0090] Specifically, the blocking card block 75 includes a first blocking card portion 751 that is consistent with the forward pushing direction of the first card pushing head 73 and a second blocking card portion 752 that is perpendicular to the forward pushing direction of the first card pushing head 73. The first blocking card portion 751 and the second blocking card portion 752 are fixedly connected or integrally formed, and the second blocking card portion 752 is lower than the first blocking card portion 751. Further preferably, the distance between the highest point of the second blocking card portion 752 and the lowest point of the first blocking card portion 751 is less than the thickness of a mahjong tile 10. Even more preferably, the second blocking card portion 752 moves in and out between the first card pushing position 421 of the card feeding device 4 and the card feeding port of the horizontal card placing device 5 to achieve blocking or passing through, and the first blocking card portion 751 moves in and out between the first card pushing position 421 and the second card pushing position 422 to achieve blocking or passing through. The conveyor belt of the card feeding device 4 extends to the first blocking card portion 751 of the blocking card block 75 between the first card pushing position 421 and the second card pushing position 422. When the first blocking card portion 751 blocks between the first card pushing position 421 and the second card pushing position 422, the second blocking card portion 752 moves out between the first card pushing position 421 of the card feeding device 4 and the card feeding port of the horizontal card placing device 5, so that the first card pushing head 73 can push a single mahjong tile 10 located at the first card pushing position 421 into the card feeding port of the horizontal card placing device 5. When the first blocking card portion 751 moves out between the first card pushing position 421 and the second card pushing position 422, the second blocking card portion 752 enters between the first card pushing position 421 of the card feeding device 4 and the card feeding port of the horizontal card placing device 5 to prevent the mahjong tile 10 from entering the card feeding port of the horizontal card placing device 5.

[0091] Specifically, the second card pushing head 74 includes a sliding portion for sliding on the head box 71 and a card pushing portion for pushing the cards, and the card pushing portion extends outward from the head box 71.

[0092] When there is one card pushing motor 72 in the card pushing head 7, a first connecting shaft 711 is provided at the bottom of the head box 71. A first connecting block 70 that can rotate around the first connecting shaft 711 is sleeved on the first connecting shaft 711. A fifth rolling bearing 701 is provided at the lower part of the first connecting block 70, and at least one sixth rolling bearing 702 is provided at the upper part of the first connecting block 70. The fifth rolling bearing 701 can rotate relative to its axis and contacts the second curve wheel 77, and the sixth rolling bearing 702 can rotate around its axis and contacts at least the second card pushing head 74. Further preferably, a first sliding groove is provided on the first mounting seat 78, and the first card pushing head 73 can slide on the first sliding groove. A second sliding groove is provided on the upper surface of the head box 71, and the second card pushing head 74 can slide on the second sliding groove.

[0093] In order to simultaneously push the first card-pushing head 73 and the second card-pushing head 74 by rotating the first connecting block 70, the first implementation manner is as follows: The first connecting block 70 is a Y-shaped block. Two sixth rolling bearings 702 are provided on the upper part of the first connecting block 70, and the two sixth rolling bearings 702 are respectively in contact with the first card-pushing head 73 and the second card-pushing head 74. In this way, when the card-pushing motor 72 rotates forward to drive the second curve wheel 77 to rotate forward, the first connecting block 70 rotates to drive the second card-pushing head 74 to push forward, and the first card-pushing head 73 is stationary or pushed forward. Further preferably, a third connecting block 731 is provided at the bottom of the first card-pushing head 73, and a fourth connecting block 741 is provided at the bottom of the second card-pushing head 74. The third connecting block 731 is fixedly connected or integrally formed with the first card-pushing head 73, and the fourth connecting block 741 is fixedly connected or integrally formed with the second card-pushing head 74. The two sixth rolling bearings 702 are respectively in contact with the vertical surfaces of the third connecting block 731 and the fourth connecting block 741.

[0094] In order to simultaneously push the first card-pushing head 73 and the second card-pushing head 74 by rotating the first connecting block 70, the second implementation manner is as follows: A sixth rolling bearing 702 is provided on the upper part of the first connecting block 70, and the sixth rolling bearing 702 is in contact with the second card-pushing head 74. A third sliding groove in the vertical direction is provided on the second card-pushing head 74, and the first card-pushing head 73 can slide up and down on the third sliding groove. In this way, when the card-pushing motor 72 rotates forward to drive the second curve wheel 77 to rotate forward, the first connecting block 70 rotates to drive the second card-pushing head 74 to push forward, and the first card-pushing head 73 is stationary or pushed forward. Further preferably, a fifth connecting block is provided at the bottom of the first card-pushing head 73, and a sixth connecting block is provided at the bottom of the second card-pushing head 74. The fifth connecting block is fixedly connected or integrally formed with the first card-pushing head 73, and the sixth connecting block is fixedly connected or integrally formed with the second card-pushing head 74. The sixth connecting block is an L-shaped block, and a third sliding groove in the vertical direction is provided at the end of the sixth connecting block. The fifth sliding groove can slide up and down on the third sliding groove.

[0095] In order to make the first pusher head 73 and the second pusher head 74 push forward and then return to their original positions, the first implementation method is as follows: A first tension spring and a second tension spring are further provided. One end of the first tension spring is connected to the first pusher head 73, and the other end is connected to the first mounting seat 78 or the machine head box 71. One end of the second tension spring is connected to the second pusher head 74, and the other end is connected to the machine head box 71. When the first pusher head 73 and the second pusher head 74 push forward and then return, the first pusher head 73 and the second pusher head 74 are respectively pulled back to their original positions by the first tension spring and the second tension spring. Further preferably, a first positioning post is provided on the first pusher head 73, and a second positioning post is provided on the upper surface of the first mounting seat 78 or the machine head box 71. The connection line between the first positioning post and the second positioning post is consistent with the forward pushing direction of the first pusher head 73. One end of the first tension spring is sleeved on the first positioning post, and the other end is sleeved on the second positioning post. In this way, when the first pusher head 73 pushes forward and then returns, it can be pulled back to its original position by the first tension spring. The second tension spring also connects the second pusher head 74 and the machine head box 71 through the positioning post, so that when the second pusher head 74 pushes forward and then returns, it can be pulled back to its original position by the second tension spring.

[0096] In order to make the first pusher head 73 and the second pusher head 74 push forward and then return to their original positions, the second implementation method is as follows: The surfaces of the first pusher head 73 and / or the second pusher head 74 in contact with the sixth rolling bearing 702 are respectively a first contact surface and a second contact surface. The first contact surface and the second contact surface are perpendicular to the forward pushing direction of the first pusher head 73 and the second pusher head 74. When the second curve wheel 77 rotates to make the sixth rolling bearing 702 or the seventh rolling bearing exert a force on the first contact surface, the second pusher head 74 pushes forward, and the first pusher head 73 remains stationary or pushes forward. When the second curve wheel 77 rotates to make the sixth rolling bearing 702 or the seventh rolling bearing exert a force on the second contact surface, the first pusher head 73 and the second pusher head 74 return to their original positions. In this way, there is no need to set a tension spring for resetting, which saves costs. Further preferably, an eighth connecting block is provided at the bottom of the first pusher head 73, and a ninth connecting block is provided at the bottom of the second pusher head 74. The eighth connecting block is fixedly connected to or integrally formed with the first pusher head 73, and the ninth connecting block is fixedly connected to or integrally formed with the second pusher head 74. The eighth connecting block is parallel to the third connecting block 731 or the fifth connecting block, and the ninth connecting block is parallel to the fourth connecting block 741 or the sixth connecting block;

[0097] When the first card-pushing head 73 and the second card-pushing head 74 are pushed forward in the first implementation manner, one of the sixth rolling bearings 702 is clamped between the eighth connecting block and the third connecting block 731 or the fifth connecting block, and the other sixth rolling bearing 702 is clamped between the ninth connecting block and the fourth connecting block 741 or the sixth connecting block. The surfaces of the third connecting block 731 and the fourth connecting block 741 in contact with the sixth rolling bearing 702 are the first contact surfaces, or the surfaces of the fifth connecting block and the sixth connecting block in contact with the sixth rolling bearing 702 are the first contact surfaces. The surfaces of the eighth connecting block and the ninth connecting block in contact with the sixth rolling bearing 702 are the second contact surfaces;

[0098] When the first card-pushing head 73 and the second card-pushing head 74 are pushed forward in the second implementation manner, the sixth rolling bearing 702 is clamped between the ninth connecting block and the fourth connecting block 741 or the sixth connecting block. The surface of the sixth connecting block or the fourth connecting block 741 in contact with the sixth rolling bearing 702 is the first contact surface, and the surface of the ninth connecting block in contact with the sixth rolling bearing 702 is the second contact surface.

[0099] Specifically, the first cam wheel 76 and the second cam wheel 77 are fixedly connected or integrally formed.

[0100] When there are two card-pushing motors 72 in the card-pushing head 7, that is, including the first card-pushing motor 72 and the second card-pushing motor 72, the first card-pushing motor 72 and the second card-pushing motor 72 are respectively located on both sides of the head box 71. The first card-pushing motor 72 is used to drive the first mounting seat 78 to move up and down, so as to control the up and down movement of the card-blocking block 75 and the first card-pushing head 73. The second card-pushing motor 72 drives the second connecting block to rotate. The upper part of the second connecting block is movably matched with the first card-pushing head 73 and / or the second card-pushing head 74, so that the second card-pushing head 74 is pushed forward, and the first card-pushing head 73 is stationary or pushed forward.

[0101] Among them, there are two ways for the first card-pushing head 73 and the second card-pushing head 74 to be pushed forward and then return to the original position, which are the same as the ways for the first card-pushing head 73 and the second card-pushing head 74 to be pushed forward and then return to the original position in one card-pushing motor 72.

[0102] Such as Figure 3The shown card delivery device 4 includes a card delivery box 41. A guide plate is provided in front of the card inlet of the card delivery box 41. A card inlet wheel with a magnet is provided at the card inlet of the card delivery box 41. A tension wheel and a driving wheel are provided in the card delivery box 41. A card outlet wheel is provided at the card outlet of the card delivery box 41. A conveyor belt is wound around the card inlet wheel, the card outlet wheel and the driving wheel and is tensioned by the tension wheel. A card aligning guide groove is provided at the card inlet. The width of the card inlet is slightly larger than the width of the selected mahjong tile 10 and shorter than the length of the mahjong tile 10. The height of the card inlet is larger than the thickness of the mahjong tile 10 and smaller than the width of the mahjong tile 10. One, two, three or four magnets are embedded in the card inlet wheel. The part of the outer circumferential surface of the card inlet wheel opposite to the magnet is designed as a plane corresponding to the size of the mahjong tile 10. After the rotation of the card inlet wheel, the mahjong tile 10 is uniformly face down. After passing through the card aligning guide groove, the mahjong tile 10 enters the card delivery device 4 in the length direction of the mahjong tile 10.

[0103] The running path of the mahjong tile 10 in the card delivery device 4 is a card delivery channel 42. The card delivery channel 42 starts from the card inlet of the card delivery box 41 and ends at the card outlet of the card delivery box 41. The card delivery channel 42 is a straight channel. The card outlet of the card delivery channel 42 is connected to the ramp card placing mechanism 6. When the mahjong tile 10 is conveyed to the card outlet of the card delivery channel 42, it is transported to the ramp card placing mechanism 6 through the card outlet wheel. Along the direction of sending out the mahjong tile 10, a first card pushing position 421 and a second card pushing position 422 are sequentially arranged outside the card outlet of the card delivery channel 42. The card inlet of the flat card placing device 5 and the first card pushing head 73 are respectively located on the opposite sides of the first card pushing position 421. The card inlet of the ramp card placing mechanism 6 and the second card pushing head 74 are respectively located on the opposite sides of the second card pushing position 422. When the blocking block 75 moves into the space between the first card pushing position 421 and the second card pushing position 422, the blocking block 75 prevents the mahjong tile 10 from entering the second card pushing position 422, and the first card pushing head 73 pushes the single mahjong tile 10 located at the first card pushing position 421 into the card inlet of the flat card placing device 5. When the blocking block 75 moves out of the space between the first card pushing position 421 and the second card pushing position 422, the mahjong tile 10 enters the second card pushing position 422, and the second card pushing head 74 pushes the single mahjong tile 10 located at the second card pushing position 422 into the card inlet of the ramp card placing mechanism 6.

[0104] Specifically, the second card blocking part 752 moves in and out between the first card pushing position 421 of the card feeding device 4 and the card feeding port of the flat card pushing and placing device 5 to achieve blocking or passing through. The first card blocking part 751 moves in and out between the first card pushing position 421 and the second card pushing position 422 to achieve blocking or passing through. The conveyor belt of the card feeding device 4 extends to the first card blocking part 751 of the card blocking block 75 between the first card pushing position 421 and the second card pushing position 422. When the first card blocking part 751 blocks between the first card pushing position 421 and the second card pushing position 422, the second card blocking part 752 moves out between the first card pushing position 421 of the card feeding device 4 and the card feeding port of the flat card pushing and placing device 5, so that the first card pushing head 73 can push a single mahjong tile 10 located at the first card pushing position 421 into the card feeding port of the flat card pushing and placing device 5. When the first card blocking part 751 moves out between the first card pushing position 421 and the second card pushing position 422, the second card blocking part 752 enters between the first card pushing position 421 of the card feeding device 4 and the card feeding port of the flat card pushing and placing device 5 to prevent the mahjong tile 10 from entering the card feeding port of the flat card pushing and placing device 5.

[0105] There are also at least two in-place detection devices, one of which is located on the first card pushing head 73 and the other is located in the ramp card placing mechanism 6.

[0106] The specific process of a card pushing motor 72 coaxially driving the first curve wheel 76 and the second curve wheel 77 and enabling the mahjong tiles 10 to enter the flat card pushing and placing device 5 and the ramp card placing mechanism 6 respectively is as follows:

[0107] As Figure 15 shown, when the flat card pushing and placing device 5 feeds cards, the initial position of the card blocking block 75 is at a low position, that is, when the first card blocking part 751 is between the first card pushing position 421 and the second card pushing position 422, when the card feeding device 4 conveys the mahjong tile 10 to the first card pushing position 421, the mahjong tile 10 is blocked by the first card blocking part 751, and after the in-place detection device located on the first card pushing head 73 senses the mahjong tile 10, as Figure 16As shown, the pushing motor 72 rotates forward to drive the first cam wheel 76 and the second cam wheel 77 to rotate forward. Among them, the first cam wheel 76 moves along a concentric circle curve, and the second cam wheel 77 moves along an ascending curve, driving the first connecting block 70 to rotate around the first connecting shaft 711 and causing the first pusher head 73 and the second pusher head 74 to push forward. At this time, the first card blocking part 751 is still located between the first pushing position 421 and the second pushing position 422, that is, the gap between the first card blocking part 751 and the card feeding track is smaller than the height of the mahjong tile 10. The second card blocking part 752 is located below the card feeding port of the horizontal pushing card loading device 5. The first pusher head 73 pushes a single mahjong tile 10 from the first pushing position 421 into the horizontal pushing card loading device 5, and the second pusher head 74 makes an empty push. Then the pushing motor 72 rotates in reverse, and the first pusher head 73 and the second pusher head 74 return to their original positions, waiting for pushing. This action is repeated until the specified number of mahjong tiles 10 is reached in the horizontal pushing card loading device 5;

[0108] After the horizontal pushing card loading device 5 is fully loaded with cards, as Figure 17 shown, the pushing motor 72 rotates in reverse to drive the first cam wheel 76 and the second cam wheel 77 to rotate. Among them, the first cam wheel 76 moves along an ascending curve, and the second cam wheel 77 moves along a concentric circle curve, driving the card blocking block 75, the first mounting seat 78 and the first pusher head 73 to rise. That is, the gap between the first card blocking part 751 and the card feeding track is greater than the height of the mahjong tile 10. The second card blocking part 752 enters the space between the first pushing position 421 of the card feeding device 4 and the card feeding port of the horizontal pushing card loading device 5 to prevent the mahjong tile 10 from entering the card feeding port of the horizontal pushing card loading device 5. The mahjong tile 10 enters the second pushing position 422. In addition, at this time, since the first pusher head 73 rises, the third connecting block 731 at its bottom no longer contacts the sixth rolling bearing 702 or the third connecting block 731 and the eighth connecting block no longer contact the sixth rolling bearing 702.

[0109] As Figure 18 shown, the pushing motor 72 continues to rotate in reverse to drive the first cam wheel 76 and the second cam wheel 77 to rotate. Among them, the first cam wheel 76 moves along a concentric circle curve, and the second cam wheel 77 moves along an ascending curve, driving the first connecting block 70 to rotate around the first connecting shaft 711 and causing the second pusher head 74 to push forward. At this time, the card blocking block 75 has moved out of the space between the first pushing position 421 and the second pushing position 422, that is, a single mahjong tile 10 has entered the second pushing position 422 and is then pushed by the second pusher head 74. The first pusher head 73 is stationary. Then the pushing motor 72 rotates forward, and the first pusher head 73 and the second pusher head 74 return to their original positions. This action is repeated until the specified number of mahjong tiles 10 is reached in the ramp card loading mechanism 6.

[0110] When there are two pushing motors 72 in the pushing head 7, the pushing process is as follows:

[0111] When the first card blocking portion 751 is located between the first card pushing position 421 and the second card pushing position 422, the second card pushing motor 72 rotates forward to drive the second connecting block to rotate, so that the second card pushing head 74 pushes forward and the first card pushing head 73 pushes forward; then the second card pushing motor 72 reverses and returns to its original position, and the first card pushing head 73 and the second card pushing head 74 return to their original positions; this action is repeated until the number of mahjong tiles 10 in the horizontal pushing device 5 reaches the specified number;

[0112] After the horizontal push card loading device 5 is fully loaded, the first card pushing motor 72 rotates forward to make the first card pushing head 73 and the card blocking block 75 rise; that is, the first card blocking portion 751 moves out from between the first card pushing position 421 and the second card pushing position 422, and the second card blocking portion 752 enters between the first card pushing position 421 of the card feeding device 4 and the card inlet of the horizontal push card loading device 5, and the mahjong tile 10 enters the second card pushing position 422;

[0113] The second card pushing motor 72 rotates forward to drive the second connecting block to rotate, so that the second card pushing head 74 is pushed forward and the first card pushing head 73 is stationary; then the second card pushing motor 72 is reversed and returns to its original position, and the second card pushing head 74 returns to its original position; this action is repeated until the number of mahjong tiles 10 in the ramp card loading mechanism 6 reaches the specified number;

[0114] The first card pushing motor 72 reverses and returns to its original position, causing the first card pushing head 73 and the card blocking block 75 to descend and return to their original positions.

[0115] like Figures 6 - 13 The flat-push card loading device 5 shown is the first implementation mode of the embodiment of the present application, which completes the card loading by first lifting the card and then pushing the card. In this implementation mode, the flat-push card loading device 5 includes a lattice plate 51, and a first card loading motor 52, a card supporting plate 553, a card pushing mechanism and a lifting mechanism installed on the lattice plate 51. The card supporting plate 553 is connected to the lattice plate 51 for sliding up and down, and the card pushing mechanism and the lifting mechanism are respectively connected to the first card loading motor 52 for transmission; it is characterized in that: the first card loading motor 52 drives the card supporting plate 553 to rise and fall through the lifting mechanism, and when the card supporting plate 553 rises to be flush with the mahjong machine table top 2, the first card loading motor 52 pushes the mahjong tiles 10 on the card supporting plate 553 onto the mahjong machine table top 2 through the card pushing mechanism; the lattice plate 51 A seesaw 56 is also provided on the top, which is located on the card-feeding side of the card-supporting plate 553 and is offset from the card-supporting plate 553. One end of the seesaw 56 is hinged to the lattice plate 51, and the other end of the seesaw 56 is driven by the first card-loading motor 52 to be lifted or lowered.

[0116] Specifically, the movable end of the seesaw 56 has two resting positions, namely, tilted upward and laid flat. When the seesaw 56 is tilted upward, the height of the highest point of the seesaw 56 from the upper surface of the card support plate 553 is not less than the thickness of a single mahjong tile 10. When the seesaw 56 is laid flat, the seesaw 56 is flush with the upper surface of the card support plate 553.

[0117] Specifically, the first card placing motor 52 is drivingly connected to the card pushing mechanism and the lifting mechanism through a gear transmission device; the gear transmission device includes a left lifting gear 531, a driving gear 532, a pushing and pulling gear 533, and a right lifting gear 534 that are sequentially meshed with each other and installed on the lattice plate 51. The driving gear 532 is connected to the output shaft of the first card placing motor 52; the lifting mechanism includes two lifting cranks 554. A support frame 555 with a bottom cam curve is provided below the card supporting plate 553. The movable ends of the two lifting cranks 554 are respectively matched and supported with the bottom cam curve of the support frame 555. The two lifting cranks 554 are respectively installed on the left lifting gear 531 and the right lifting gear 534; the card pushing mechanism includes a card pushing cam 541, a transmission main shaft 542, two card pushing rockers 543, a card pushing plate 544, and a first connecting member 545. The card pushing cam 541 is fixedly connected to the pushing and pulling gear 533. One end of the first connecting member 545 is in driving cooperation with the card pushing cam 541. The other end of the first connecting member 545 is fixedly installed on the transmission main shaft 542. The transmission main shaft 542 is installed on the lattice plate 51 and can rotate. The lower ends of the two card pushing rockers 543 are respectively fixedly installed on the transmission main shaft 542. The upper ends of the two card pushing rockers 543 jointly push the card pushing plate 544 to move; the card pushing plate 544 is fixedly installed on a flat pushing slider. The flat pushing slider is slidably connected to the card pushing support 546. The flat pushing slider is driven by the card pushing rocker 543 to translate. The card pushing support 546 is fixedly connected to the card supporting plate 553 and synchronously lifted and lowered.

[0118] It should be noted that to ensure good transmission effect, the transmission main shaft 542, the two card pushing rockers 543, and the first connecting member 545 are integrally injection molded during the processing.

[0119] Specifically, a rocker cam 57 and a rocker 56 gear coaxially fixed with the rocker cam 57 are installed on the lattice plate 51. The rocker 56 gear is in transmission cooperation with the left lifting gear 531 or the right lifting gear 534.

[0120] It should be noted that the rocker cam 57 can also be installed on the lifting crank 554 and integrally formed with the lifting crank 554. A first protrusion portion matching the rocker cam 57 is provided on the lower surface of the rocker 56. Through the rotation of the lifting crank 554 and the cooperation between the rocker cam 57 and the first protrusion portion, the rocker 56 can still have two staying positions of tilting upward and lying flat.

[0121] Specifically, the left lifting gear 531 or the right lifting gear 534 is a double-layer gear. One layer of teeth is a complete tooth and is in meshing transmission with the driving gear 532 or the pushing and pulling gear 533, and the other layer of gear is an incomplete tooth and is in meshing transmission with the rocker 56 gear.

[0122] Specifically, the card-pushing support 546 is installed below the card-holding plate 553. Two sliding rods 547 are fixed on the card-pushing support 546. The flat-pushing slider slides on the sliding rods 547 and is reset by a spring. Two extension parts 5481 extend upward from the flat-pushing slider. The card-pushing plate 544 is installed on the two extension parts 5481. Third rolling bearings 5431 are provided at the tops of the two card-pushing rockers 543. When the card-pushing support 546 and the card-holding plate 553 rise, the two third rolling bearings 5431 are respectively in contact with both sides of the flat-pushing slider.

[0123] As Figure 7 and Figure 8 shown, in this embodiment, the card-stacking process is as follows: When the seesaw 56 tilts upward, the height difference between the highest point and the lowest point of the seesaw 56 is at least the thickness of a single mahjong tile 10, and the tilted end of the seesaw 56 is connected to the first card-pushing position 421. In this way, the first card-pushing head 73 can push the mahjong tile 10 onto the card-holding plate 553. When the first layer of mahjong tiles 10 is full, the seesaw 56 is flattened. At this time, the seesaw 56 is flush with the upper surface of the card-holding plate 553, and the upper surface of the single layer of mahjong tiles 10 is flush with or slightly lower than the first card-pushing position 421. The first card-pushing head 73 can continue to push the cards until the mahjong tiles 10 reach the specified number of stacks, completing the card stacking.

[0124] As Figure 9 shown is a schematic diagram of the card-holding plate 553 starting to rise during the card-lifting process of the flat-pushing card-loading device 5. As Figure 10 shown is a schematic diagram of the card-holding plate 553 rising to the highest position, that is, being flush with or slightly higher than the mahjong tabletop 2 during the card-lifting process of the flat-pushing card-loading device 5. As Figure 11 shown is a schematic diagram of the card-holding plate 553 rising to the highest position and the card-pushing plate 544 having been pushed to the farthest position during the card-lifting process of the flat-pushing card-loading device 5. As Figure 12 shown is a schematic diagram of the card-holding plate 553 rising to the highest position and the card-pushing plate 544 having been retracted to the original position during the card-lifting process of the flat-pushing card-loading device 5. As Figure 13 shown is a schematic diagram of the card-holding plate 553 descending and the seesaw 56 still being in the flattened state after the card-pushing of the flat-pushing card-loading device 5 is completed.

[0125] Specifically, the first way for the flat-push card-dealing device 5 to lift the cards first and then push the cards is as follows: There are four first inner card outlets 25 and first covers distributed in a rectangular shape on the mahjong table 2 of the mahjong machine. The upper surface of the first cover is flush with the mahjong table 2 and seals the first inner card outlet 25. A plurality of first ejector rods are also distributed on the card-supporting plate 553. The first cover is connected to the first ejector rods. The first card-dealing motor 52 drives two lifting cranks 554 to rotate, causing the card-supporting plate 553 to rise, and further causing a plurality of first ejector rods to lift the first cover. When the card-supporting plate 553 rises to be flush with the tabletop or higher than the tabletop, the push-card rocker 543 pushes the push-card plate 544 to push out the mahjong tiles 10. Further preferably, the first cover is fixedly connected or integrally formed with the first ejector rods. It should be noted that the first cover can also be lifted by the mahjong tiles 10.

[0126] Specifically, the second way for the flat-push card-dealing device 5 to lift the cards first and then push the cards is as follows: There are four second inner card outlets 25 and second covers distributed in a rectangular shape on the mahjong table 2 of the mahjong machine. The upper surface of the second cover is flush with the mahjong table 2 and seals the second inner card outlet 25. At least two second ejector rods are distributed on the card-supporting plate 553. One side of the second cover is hinged to the mahjong table 2 and the other side can be lifted by at least two second ejector rods. The first card-dealing motor 52 drives two lifting cranks 554 to rotate, causing the card-supporting plate 553 to rise, and further causing at least two second ejector rods to lift the second cover. When the card-supporting plate 553 rises to be flush with the tabletop or higher than the tabletop, the push-card rocker 543 pushes the push-card plate 544 to push out the mahjong tiles 10. It should be noted that the second cover can also be lifted by the mahjong tiles 10.

[0127] In the embodiment of this application, the flat-push card-dealing device 5 is in the second implementation manner, which still adopts the card-dealing method of lifting the cards first and then pushing the cards. The difference between this implementation manner and the first implementation manner is that there is no tipping plate 56 and the structures related to the tipping plate 56.

[0128] In this implementation manner, the card-stacking process is as follows: In the initial state, the card-supporting plate 553 has a height matching the first card-pushing position 421. The first card-pushing head 73 can push the mahjong blocks through the first card-pushing position 421 onto the card-supporting plate 553. When the first layer of mahjong tiles 10 is fully covered, the first card-dealing motor 52 drives the lifting crank 554 to rotate, causing the card-supporting plate 553 to descend by the thickness of one mahjong tile 10. Then the first card-pushing head 73 can continue to push the cards until the mahjong tiles 10 reach the specified number of stacks, completing the card-stacking.

[0129] The card-lifting method can adopt the card-lifting method of the flat-pushing card-loading device 5 in the first embodiment. However, during the card-stacking process, the card-supporting plate 553 has a descending process. If the first cover plate and the first ejector rod are fixedly connected or integrally formed, then when the card-supporting plate 553 descends, it will also drive the first cover plate to descend, which is obviously not advisable. Therefore, to avoid this situation, the first cover plate and the first ejector rod are movably connected, so that when the card-supporting plate 553 ascends and descends within a certain height range, it will not drive the first cover plate to ascend and descend. When the card-supporting plate 553 exceeds this height range, the ascending and descending of the card-supporting plate 553 can drive the first cover plate to ascend and descend.

[0130] The flat-pushing card-loading device 5 in the embodiment of this application is the third embodiment. The difference between this embodiment and the first embodiment is that it adopts a card-loading method of first pushing the cards and then lifting the cards, that is, the lifting mechanism is not used to control the lifting of the card-supporting plate 553, but is used to control the lifting of the cover plate on the mahjong table 2. The specific structure can refer to the Chinese patent document with the publication number CN104436635A.

[0131] Its card-stacking process is the same as that of the first embodiment.

[0132] Its card-lifting process is as follows: After the card-stacking is completed, the lifting mechanism controls the cover plate to descend to a height matching the card-supporting plate 553, then the card-pushing mechanism pushes the mahjong tiles 10 onto the cover plate, and then the lifting mechanism controls the cover plate to rise to a height flush with the mahjong table 2 to complete the card-lifting.

[0133] The flat-pushing card-loading device 5 in the embodiment of this application is the fourth embodiment. The difference between this embodiment and the third embodiment is that there is no rocker 56 and the structures related to the rocker 56. The specific structure can refer to the Chinese patent document with the publication number CN201271493Y.

[0134] Its card-stacking method is the same as that of the second embodiment.

[0135] Its card-lifting method is the same as that of the third embodiment.

[0136] It should be noted that the biggest difference between the flat-pushing card-loading device 5 in the first embodiment and the second embodiment and the flat-pushing card-loading device 5 in the third embodiment and the fourth embodiment is that:

[0137] In the first and second embodiments, the mahjong tiles 10 in the flat push tile placing device 5 are first lifted onto the mahjong machine table 2 and then the push tile rocker 543 pushes the push tile plate 544 to push out the mahjong tiles 10. While in the third and fourth embodiments, the mahjong tiles 10 in the flat push tile placing device 5 are first pushed out by the push tile rocker 543 pushing the push tile plate 544 and then lifted onto the mahjong machine table 2. That is, the space occupied by pushing out the mahjong tiles 10 in the flat push tile placing device 5 in the first and second embodiments is transferred to the mahjong machine table 2 of the mahjong machine, thereby making the internal space of the mahjong machine more abundant and further reducing the volume of the mahjong machine.

[0138] As Figure 19 and Figure 22 shown, the ramp tile placing mechanism 6 is the first embodiment of the embodiment of the present application. In this embodiment, the ramp tile placing mechanism 6 includes a tile placing driving mechanism and a tile placing bracket. The tile placing bracket is provided with a first tile placing guide rail 63 for storing mahjong tiles 10 and a tile placing push head 612 that moves along the first tile placing guide rail 63 to implement tile placing. The first tile placing guide rail 63 is arranged along the width direction of the mahjong tiles 10 to store a single layer of mahjong tiles 10, and a section of the first tile placing guide rail 63 close to the tile outlet on the mahjong machine table 2 is a ramp section that extends obliquely upward to connect with the mahjong machine table 2. The tile placing driving mechanism includes a tile placing chain 611. The tile placing push head 612 is installed on the tile placing chain 611. The tile placing chain 611 moves along the bottom groove of the first tile placing guide rail 63 and matches the tile placing trajectory of the mahjong tiles 10. A first flap 23 is provided at the tile outlet on the mahjong machine table 2. One side of the first flap 23 is hinged to the mahjong machine table 2 or the tile placing bracket. The tile placing chain 611 moves to drive the tile placing push head 612 to move, thereby pushing the mahjong tiles 10 to advance along the first tile placing guide rail 63 and lifting the other side of the first flap 23, and then pushing the mahjong tiles 10 onto the mahjong machine table 2 along the ramp section.

[0139] Specifically, the tile placing push head 612 is connected to the tile placing chain 611 through two lifting rods 6122 so as to slide up and down relative to the tile placing chain 611. The tile placing push head 612 is fixed or integrally formed at the upper ends of the two lifting rods 6122. A base 6121 is fixed or integrally formed at the lower ends of the two lifting rods 6122. The two lifting rods 6122 pass through the chain links of the tile placing chain 611 and are respectively sleeved with spring members 6124. The lower ends of the spring members 6124 abut against the base 6121, and the upper ends abut against the tile placing chain 611. A roller 6125 is further provided on the base 6121, and a first guide rail 64 that cooperates with the roller 6125 is further provided on the tile placing bracket. The first guide rail 64 is located below the ramp section of the first tile placing guide rail 63.

[0140] Specifically, the first card - feeding guide rail 63 includes an inner guide rail 631 and an outer guide rail 632 distributed on the inner and outer sides of the bottom groove. The inner guide rail 631 includes a horizontal first linear guide rail 6311 and an upward - inclined first arc - shaped guide rail 6312. The outer guide rail 632 includes a horizontal second linear guide rail 6321 and an upward - inclined second arc - shaped guide rail 6322. Further preferably, the inner guide rail 631 and the outer guide rail 632 are integrally formed by injection molding. Specifically, a groove for accommodating the card - feeding chain 611 and the card - feeding pusher head 612 is provided between the first linear guide rail 6311 and the second linear guide rail 6321 to connect them into one body, which is convenient for installation and can improve the matching accuracy between the inner guide rail 631 and the outer guide rail 632.

[0141] Specifically, the card - pushing surface on the card - feeding pusher head 612 includes a vertical surface and an inclined surface 61232. Further preferably, a smooth transition is provided between the vertical surface and the inclined surface 61232. When the card - feeding pusher head 612 pushes cards in the first card - feeding guide rail 63, its card - pushing surface is the vertical surface in the horizontal first linear guide rail 6311 and the second linear guide rail 6321, and its card - pushing surface is the inclined surface 61232 in the upward - inclined first arc - shaped guide rail 6312 and the second arc - shaped guide rail 6322.

[0142] Specifically, the first card - feeding guide rail 63 is made of a material with a smooth and wear - resistant surface, such as polyoxymethylene, polytetrafluoroethylene, etc., or a smooth and wear - resistant patch is installed on the first card - feeding guide rail 63. The first card - feeding guide rail 63 is installed on the card - feeding bracket as an independent component, and the card - feeding bracket is made of a material with relatively poor performance and lower price. This can not only meet the usage requirements but also reduce the manufacturing cost of the machine. The first card - feeding guide rail 63 is preferably positioned in cooperation with the card - feeding bracket through a plurality of T - shaped convexes and locked and fixed by fasteners for convenient installation.

[0143] Specifically, one side of the first flap 23 is hinged to the mahjong tabletop 2 through a hinge. The fixed part of the hinge is fixedly connected to the bottom of the mahjong tabletop 2 of the mahjong machine, the movable part of the hinge is fixedly connected to the bottom of the first flap 23, and a torsion spring that gives the movable part a downward rotation tendency is sleeved on the rotating shaft of the hinge. The fixed part of the hinge extends to form a limiting part that restricts the downward rotation range of the movable part. In this way, the resistance of the first flap 23 to the mahjong tiles 10 is smaller, and it will not affect card - feeding and disrupt the mahjong tiles 10. Using the hinge form and torsion spring reset, the structure is simple, reliable, small in size, and low in cost.

[0144] For the four ramp card - feeding mechanisms 6 distributed in a rectangle in the mahjong machine:

[0145] Such as Figure 20The four first card loading guide rails 63 in the four slope card loading mechanisms 6 shown are connected at the ends to form a quadrilateral, and the head and tail connections of two adjacent first card loading guide rails 63 are staggered up and down to maximize the use of space and make room for the second card pushing head 74 to facilitate the second card pushing head 74 to push cards.

[0146] like Figure 21 The four card loading chains 611 in the four slope card loading mechanisms 6 shown are connected end to end to form a closed loop and are guided by at least two diagonally arranged chain guide blocks 613, which are in smooth contact with the card loading chains 611 and are fixed on the card loading bracket or the base plate 1.

[0147] like Figure 20 In the two first guide rails 64 in the two adjacent ramp card loading mechanisms 6 shown, one first guide rail 64 is located below the first arc guide rail 6312 of one first card loading guide rail 63, and the other first guide rail 64 is located below the second arc guide rail 6322 of the other first card loading guide rail 63. Such arrangement is because the four first card loading guide rails 63 are surrounded by a rounded rectangle and are arranged in an upper and lower staggered manner, which results in the overlapping of the card pushing trajectories of the four card pushing heads during the ramp card loading process, that is, the motion trajectory of the initial segment of a card loading push head 612 and the motion trajectory of the subsequent card loading push head 612 in the final segment overlap in the horizontal direction, but a card loading push head 612 needs to be pushed horizontally in the initial segment and needs to rise in the final segment, therefore, the adjacent first guide rails 64 should be located below the first arc guide rail 6312 and the second arc guide rail 6322, respectively, to avoid overlapping of the card pushing trajectories.

[0148] Specifically, a second card loading motor 68 is also provided, and the second card loading motor 68 is located outside any slope card loading mechanism 6 and cooperates with the card loading chain 611 in transmission.

[0149] The card loading process of the slope card loading mechanism 6 is as follows: the second card loading motor 68 drives the card loading chain 611 to move in the forward direction, thereby driving the four card loading push heads 612 to move at the same time, and the card loading push heads 612 push the single-layer mahjong tiles 10 to move forward in the first card loading guide rail 63 along its width direction, and in the process of rising, the mahjong tiles 10 push up the first flap 23 until the card loading push heads 612 push all the mahjong tiles 10 onto the mahjong machine table 2, and then the second card loading motor 68 reverses to make the card loading push heads 612 return to their original position, and the first flap 23 also returns to its original position under the action of the torsion spring, thereby completing the card loading.

[0150] The sloped card loading mechanism 6 in this embodiment can make the entire card loading process smoother, so that the mahjong tiles 10 will not stagnate or get stuck due to the slope being too steep.

[0151] It should be noted that in this embodiment, the first card - placing guide rail 63 in the ramp card - placing mechanism 6 extends to the second card - pushing position 422 to form a second card - supporting table for storing the mahjong tiles 10. Since the four card - placing chains 611 are connected end to end to form a closed loop in the groove formed by the inner guide rail and the outer guide rail, and drive the card - placing card - pusher head 612 to reciprocate back and forth, there is an overlap in the position between the card - placing card - pusher head 612 and the second card - pusher head 74, and there is a relatively wide groove in the middle of the second card - supporting table that allows the mahjong tiles 10 to fall and get stuck. Therefore, a first avoidance groove is provided on the second card - pusher head 74, and a fixing plate is provided at the second card - supporting table. The lower end of the fixing plate is hinged with a movable plate through a hinge. A first card - supporting block is provided at the upper end of the fixing plate, and a second card - supporting block is provided at the upper end of the movable plate. The first card - supporting block and the second card - supporting block together form an openable and closable second card - supporting table. Chamfers are provided on the sides of the first card - supporting block and the second card - supporting block close to the card - placing card - pusher head 612. In this way, when the card - placing card - pusher head 612 pushes the cards, it can avoid the second card - pusher head 74 and open the movable plate along the chamfer to push the mahjong tiles 10. The specific structure can refer to the Chinese patent document with the publication number CN201949628U.

[0152] As Figure 23 shown, the ramp card - placing mechanism 6 of this second implementation manner of the embodiment of the present application is different from the ramp card - placing mechanism 6 in the first implementation manner in that:

[0153] The ramp card - placing mechanism 6 includes a second card - placing guide rail and a second flap 24. The second flap 24 is located at the out - card port of the mahjong table 2. The second flap 24 is hinged to the mahjong table 2, and the second flap 24 has two stop positions: flush with the mahjong table 2 and docked with the second card - placing guide rail. During the ramp card - placing process, the second flap 24 drops and docks with the second card - placing guide rail. The card - placing card - pusher head 612 pushes the single - layer mahjong tiles 10 along its length direction to the end of the second card - placing guide rail. In this way, the last mahjong tile 10 is also pushed onto the second flap 24. Then the second flap 24 rises to be flush with the tabletop, and then the card - placing card - pusher head 612 returns to its original position to complete the card - placing.

[0154] Specifically, the ramp card - placing mechanism 6 further includes a card - placing chain. The second card - placing guide rail includes an inner guide rail and an outer guide rail distributed on the inner and outer sides of the bottom groove. The inner guide rail includes a horizontally arranged third linear guide rail and a third arc - shaped guide rail. The outer guide rail includes a horizontally arranged fourth linear guide rail and a fourth arc - shaped guide rail. The card - placing chain is located in the bottom groove between the inner guide rail and the outer guide rail and matches the card - placing trajectory of the mahjong tiles. Further preferably, the inner guide rail and the outer guide rail are integrally formed, which is convenient for installation and can improve the matching accuracy between the inner guide rail and the outer guide rail.

[0155] Specifically, a flap cam 66 and a flap top rod 67 are also provided. The flap cam 66 is transmission-connected to the first card-loading motor 52 in the horizontal push card-loading device 5. One end of the flap top rod 67 is hinged to the lattice plate 51, and the other end of the flap top rod 67 is driven by the flap cam 66 to swing up and down and is connected to the second flap 24, so that the second flap 24 has two stop positions, flush with the mahjong machine table top 2 and docking with the second card-loading guide rail. Such an arrangement not only has a reasonable spatial layout, but also saves a card-lifting motor compared to the prior art.

[0156] The ramp card loading mechanism 6 for completing the card loading through this implementation mode can have various card loading drive mechanisms, such as using chain drive to complete the card loading, and the specific structure can refer to the Chinese patent document with publication number CN208877886U or other similar chain drive structures. The card loading can also be completed in the form of wire rope drive, and the specific structure can refer to the Chinese patent document with publication number CN105413166A or other similar chain drive structures. The card loading can also be completed in the form of synchronous belt, and the specific structure can refer to the Chinese patent document with publication number CN208694237U or other similar synchronous belt drive structures.

[0157] It is worth noting that the second embodiment of the slope card loading mechanism 6 can adopt a variety of card loading drive mechanisms because its card loading drive mechanism only acts on the horizontal section of the card loading process and the card pushing trajectories of adjacent card loading pushing heads 612 do not overlap.

[0158] The method of loading cards on the above-mentioned mahjong machine is as follows:

[0159] The mahjong tiles 10 on the shuffling tray 3 are sent to the bottom of the card inlets of the four card feeding devices 4, and are sucked up by the card suction wheels in the card feeding devices 4 to enter the card feeding channel 42 and are straightened for transportation along its length direction; the card feeding device 4 is sequentially provided with a first card pushing position 421 and a second card pushing position 422 along the direction in which the mahjong tiles 10 are sent out, and the card pushing machine head 7 pushes the single mahjong tile 10 on the first card pushing position 421 to the flat push card loading device 5, and the card pushing machine head 7 pushes the single mahjong tile 10 on the second card pushing position 422 to the slope card loading mechanism 6; when a sufficient number of mahjong tiles 10 are stored in the flat push card loading device 5 and the slope card loading mechanism 6, the arranged mahjong tiles 10 are transported to the mahjong machine tabletop 2 by the flat push card loading device 5 and the slope card loading mechanism 6.

[0160] Specifically, four inner card - discharging ports 25 and four outer card - discharging ports 26 are provided on the mahjong machine table 2. The four inner card - discharging ports 25 are respectively located at the four sides of a rectangle, and the four outer card - discharging ports 26 are located outside the inner card - discharging ports 25 and are respectively close to the four corners of the rectangle. The flat - pushing card - placing device 5 sends two layers of mahjong tiles 10 to the mahjong machine table 2 through the four inner card - discharging ports 25, and the ramp card - placing mechanism 6 sends a single layer of tiles to the mahjong machine table 2 through the four outer card - discharging ports 26.

[0161] In the flat - pushing card - placing device 5, the first way of stacking tiles is as follows: It includes a tile - supporting plate 553 for storing two - layer mahjong tiles 10. A tipping plate 56 is provided on the card - feeding port side of the tile - supporting plate 553. The tipping plate 56 is flush with the tile - supporting plate 553 and is arranged with dislocation avoidance. One end of the tipping plate 56 close to the first tile - pushing position 421 can tilt upwards. When the tile - supporting plate 553 receives the first layer of mahjong tiles 10, the movable end of the tipping plate 56 tilts up and matches the height of the first tile - pushing position 421. The mahjong tiles 10 are pushed from the first tile - pushing position 421 along the tipping plate 56 onto the tile - supporting plate 553. When the first layer of mahjong tiles 10 on the tile - supporting plate 553 is full, the movable end of the tipping plate 56 drops, and then it receives the second layer of mahjong tiles 10. At this time, the upper surface of the first layer of mahjong tiles 10 matches the height of the first tile - pushing position 421, and the tile - pushing head 7 continues to push the tiles until the second layer of mahjong tiles 10 is full.

[0162] The second way of stacking tiles is as follows: It includes a tile - supporting plate 553 for storing two - layer mahjong tiles 10. The tile - supporting plate 553 has two stopping positions that match the height of the first tile - pushing position 421 and are at least one mahjong - tile 10 thickness lower than the first tile - pushing position 421. When the tile - supporting plate 553 receives the first layer of mahjong tiles 10, the tile - supporting plate 553 matches the height of the first tile - pushing position 421, and the mahjong tiles 10 are conveyed to the tile - supporting plate 553 through the first tile - pushing position 421. When the first layer of mahjong tiles 10 on the tile - supporting plate 553 is full, the tile - supporting plate 553 descends, and the descending height is at least the thickness of one mahjong tile 10. The tile - pushing head 7 continues to push the tiles until the second layer of mahjong tiles 10 is full.

[0163] The first way of lifting tiles is as follows: When receiving a card - placing signal, which is often sent by a player, the tile - supporting plate 553 rises to a position flush with or higher than the mahjong machine table 2, and then the mahjong tiles 10 on the tile - supporting plate 553 are pushed out onto the mahjong machine table 2, and then the tile - supporting plate 553 descends to its original position to wait for the next round of tile stacking.

[0164] The second way of lifting tiles is as follows: When receiving a card - placing signal, which is often sent by a player, the cover plate on the inner card - discharging port 25 descends to a height matching the tile - supporting plate 553, and then the mahjong tiles 10 on the tile - supporting plate 553 are pushed out onto the cover plate, and then the cover plate rises to be flush with the mahjong machine table 2.

[0165] In the card-dealing mechanism 6 on the slope, the first card-dealing method is as follows: When receiving a card-dealing signal, which is often sent by the player, the card-dealing pusher head 612 pushes the mahjong tiles 10 forward along the first card-dealing guide rail 63 and can lift the first flap 23 hinged to the mahjong table 2 at the out-card opening 26 until all the mahjong tiles 10 are pushed onto the table. Then, the card-dealing pusher head 612 returns to its original position. After the card-dealing is completed, the distribution of the mahjong tiles 10 is as shown in Figure 25 shown.

[0166] The second card-dealing method is as follows: When receiving a card-dealing signal, which is often sent by the player, the second flap 24 hinged to the mahjong table 2 at the out-card opening 26 drops down and is connected to the second card-dealing guide rail. The card-dealing head pushes the mahjong tiles 10 on the second card-dealing guide rail onto the second flap 24, and the second flap 24 flips up to be flush with the mahjong table 2. After the card-dealing is completed, the distribution of the mahjong tiles 10 is as shown in Figure 26 shown.

[0167] It should be noted that in the description of this specification, "flush" and "height matching" between surface A and surface B both mean that the height difference between surface A and surface B is within 5 mm.

[0168] Embodiment 2:

[0169] The difference between this embodiment of the present application and Embodiment 1 lies in the structure of the card-pushing head, the card-pushing method, and the lifting method of the card-blocking block.

[0170] As shown in Figure 27 the card-pushing head includes a head box 71, a card-pushing motor 72, a first card-pushing head 73, a second card-pushing head 74, and a card-blocking block 75. The card-pushing motor 72 is installed on the head box 71; the first card-pushing head 73 is installed on the head box 71 and is driven by the card-pushing motor 72 to translate and slide relative to the head box 71; the second card-pushing head 74 is installed on the head box 71 and is driven by the card-pushing motor 72 to translate and slide relative to the head box 71; the card-blocking block 75 is installed on the head box 71 and is driven by the card-pushing motor 72 to lift up and down relative to the head box 71; and a first card-pushing position 421 and a second card-pushing position 422 are arranged front and back along the conveying direction of the mahjong tiles 10. The card-blocking block 75 is arranged between the first card-pushing position 421 and the second card-pushing position 422 and can lift up and down to block the mahjong tiles 10 and allow the mahjong tiles 10 to pass through. The first card-pushing head 73 is located on one side of the first card-pushing position 421 and translates and slides in and out of the first card-pushing position 421 to push the cards, and the second card-pushing head 74 is located on one side of the second card-pushing position 422 and translates and slides in and out of the second card-pushing position 422 to push the cards.

[0171] It should be noted that in this embodiment, the pushing card motor 72 is located on the side of the second pushing card head 74. It is also possible to place the pushing card motor 72 on the side of the first pushing card head 73 as in Embodiment 1. The specific structures of the first pushing card head 73, the second pushing card head 74, and the card blocking block 75 can refer to Embodiment 1.

[0172] As Figures 28 - 32 shown, a pushing card head driving mechanism is further installed in the machine head box 71. The pushing card head driving mechanism is used to control the first pushing card head 73 and the second pushing card head 74 to perform card pushing. Among them, the pushing card motor 72 rotates forward to drive the first pushing card head 73 to perform card pushing, and the pushing card motor 72 rotates forward to drive the second pushing card head 74 to perform card pushing. The pushing card head driving mechanism includes a first pushing card wheel 761 and a second pushing card wheel 771 that are in transmission cooperation with the pushing card motor 72. The first pushing card wheel 761 is in transmission connection with the first pushing card head 73, and the second pushing card wheel 771 is in transmission connection with the second pushing card head 74. The pushing card motor 72 drives the first pushing card wheel 761 to rotate, thereby causing the first pushing card head 73 to perform card pushing; the pushing card motor 72 drives the second pushing card wheel 771 to rotate, thereby causing the second pushing card head 74 to perform card pushing; further preferably, it further includes a camshaft 792 in transmission cooperation with the pushing card motor 72, and a one-way bearing A791 sleeved on the camshaft 792. The first pushing card wheel 761 is in transmission cooperation with the outer surface of the one-way bearing A791. The second lifting wheel 772 is fixedly or movably installed on the camshaft 792. The pushing card motor 72 rotates forward to drive the first pushing card wheel 761 to rotate, thereby causing the first pushing card head 73 to perform card pushing, that is, the first pushing card head 73 translates and slides in and out of the first card pushing position 421 to achieve card pushing. At this time, the second pushing card head 74 can perform an empty push or remain stationary; the pushing card motor 72 rotates in reverse to drive the second pushing card wheel 771 to rotate, thereby causing the second pushing card head 74 to perform card pushing, that is, the second pushing card head 74 translates and slides in and out of the second card pushing position 422 to achieve card pushing. At this time, the first pushing card head 73 remains stationary.

[0173] When the second pushing card wheel 771 is fixedly installed on the camshaft 792, the pushing card motor 72 drives the camshaft 792 to rotate forward, the first pushing card head 73 performs card pushing, the second pushing card wheel 771 rotates forward and the second pushing card head 74 performs an empty push. When the pushing card motor 72 drives the camshaft 792 to rotate in reverse, the first pushing card head 73 remains stationary, the second pushing card wheel 771 rotates in reverse and the second pushing card head 74 performs card pushing.

[0174] When the second card-pushing wheel 771 is movably installed on the camshaft 792, a one-way bearing B793 is also sleeved on the camshaft 792. The outer surface of the one-way bearing B793 is in driving cooperation with the second card-pushing wheel 771. When the card-pushing motor 72 drives the camshaft 792 to rotate forward, the first card-pushing head 73 implements card pushing, and the second card-pushing wheel 771 and the second card-pushing head 74 are stationary. When the card-pushing motor 72 drives the camshaft 792 to rotate reversely, the first card-pushing head 73 is stationary, the second card-pushing wheel 771 rotates reversely, and the second card-pushing head 74 implements card pushing.

[0175] Specifically, a first swing arm 794 and a second swing arm 795 are further provided in the machine head box 71. The lower ends of the first swing arm 794 and the second swing arm 795 are hinged to the machine head box 71. The lower part of the first swing arm 794 is in movable cooperation with the first card-pushing wheel 761, and the lower part of the second swing arm 795 is in movable cooperation with the second card-pushing wheel 771. The upper part of the first swing arm 794 is in movable cooperation with the first card-pushing head 73, and the upper part of the second swing arm 795 is in movable cooperation with the second card-pushing head 74. When the card-pushing motor 72 drives the first card-pushing wheel 761 to rotate forward, the first swing arm 794 is driven to swing, thereby pushing the first card-pushing head 73 to implement card pushing. At this time, the second card-pushing wheel 771 can rotate forward together or be stationary. When the card-pushing motor 72 drives the second card-pushing wheel 771 to rotate reversely, the second swing arm 795 is driven to swing, thereby pushing the second card-pushing head 74 to implement card pushing. At this time, the first card-pushing wheel 761 is stationary. Further preferably, for the specific structure of the lower part of the first swing arm 794 in movable cooperation with the first card-pushing wheel 761, reference can be made to the specific structure of the first connecting block 70 in movable cooperation with the first curve wheel 76 in Embodiment 1. For the specific structure of the upper part of the first swing arm 794 in movable cooperation with the first card-pushing head 73, reference can be made to the specific structure of the first connecting block 70 in movable cooperation with the first card-pushing head 73 in Embodiment 1, that is, the rotation of the first card-pushing wheel 761 is converted into the swinging motion of the first swing arm 794 through a rolling bearing, and then the swinging of the first swing arm 794 is converted into the card-pushing motion of the first card-pushing head 73. By setting a tension spring or arranging a first contact surface and a second contact surface that cooperate with the rolling bearing before and after the card-pushing direction, when the first card-pushing wheel 761 no longer applies a forward pushing force to the first swing arm 794, the first swing arm 794 returns to its original position; and for the specific structure of the upper part of the second swing arm 795 in movable cooperation with the second card-pushing head 74, reference can be made to the specific structure of the first connecting block 70 in movable cooperation with the second card-pushing head 74 in Embodiment 1, that is, the swinging of the second swing arm 795 is converted into the card-pushing motion of the second card-pushing head 74 through a rolling bearing, and by setting a tension spring or arranging a first contact surface and a second contact surface that cooperate with the rolling bearing before and after the card-pushing direction, when the second card-pushing wheel 771 no longer applies a forward pushing force to the second swing arm 795, the second swing arm 795 returns to its original position.

[0176] With such a setting, the pushing motor 72 rotates forward to complete the pushing action of the first pushing head 73, and rotates reversely to complete the pushing action of the second pushing head 74. During a complete process of placing the mahjong tiles, the pushing motor 72 has only one forward and reverse rotation switch. Compared with the case in Embodiment 1 where the pushing motor 72 has a forward and reverse rotation switch for each pushed mahjong tile 10, the pushing head in this embodiment is more in line with the working characteristics of the pushing motor 72, and can significantly improve the working life of the pushing motor 72.

[0177] As Figures 28 - 32 shown, a lifting mechanism for the blocking tile 75 is further installed in the head box 71. The lifting mechanism for the blocking tile 75 is used to control whether the blocking tile 75 is located between the first pushing position 421 and the second pushing position 422. When the pushing motor rotates forward, the blocking tile is located between the first pushing position (421) and the second pushing position (422). When the pushing motor rotates reversely, the blocking tile is no longer located between the first pushing position (421) and the second pushing position (422).

[0178] The lifting mechanism for the blocking tile 75 includes a first lifting wheel 762 and a second lifting wheel 772 that are in transmission cooperation with the pushing motor 72. The first lifting wheel 762 and the second lifting wheel 772 are respectively in transmission connection with the blocking tile 75. The pushing motor 72 drives the first lifting wheel 762 to rotate, thereby enabling the blocking tile 75 to have a low-position staying position. The pushing motor 72 drives the second lifting wheel 772 to rotate, thereby enabling the blocking tile 75 to have a high-position staying position. Further preferably, it further includes a camshaft 792 in transmission cooperation with the pushing motor 72, and a one-way bearing A791 and a one-way bearing B793 sleeved on the camshaft 792. The first lifting wheel 762 is in transmission cooperation with the outer surface of the one-way bearing A791, and the second lifting wheel 772 is in transmission cooperation with the outer surface of the one-way bearing B793. When the pushing motor 72 rotates forward, it drives the first lifting wheel 762 to rotate, thereby enabling the blocking tile 75 to have a low-position staying position, that is, the blocking tile 75 is located between the first pushing position 421 and the second pushing position 422. When the pushing motor 72 rotates reversely, it drives the second lifting wheel 772 to rotate, thereby enabling the blocking tile 75 to have a high-position staying position, that is, the blocking tile 75 is no longer located between the first pushing position 421 and the second pushing position 422.

[0179] Specifically, a rotating block 796 and a baffle spring piece 797 are further provided in the head box 71. The baffle spring piece 797 is installed in the head box 71. A lifting block 753 is provided on the lower surface of the baffle block 75. One end of the rotating block 796 is movably matched with the baffle spring piece 797, and the other end is hinged to the lifting block 753. A second baffle dial block 7962 is provided on the front side of the rotating block 796, and a first baffle dial block 7961 is provided on the rear side. The first baffle dial block 7961 and the second baffle dial block 7962 are fixedly connected or integrally formed with the rotating block 796. The first baffle dial block 7961 is movably matched with the first lifting wheel 762, and the second baffle dial block 7962 is movably matched with the second lifting wheel 772. The pushing card motor 72 drives the first lifting wheel 762 to rotate forward, thereby driving the rotating block 796 to rotate, driving the lifting block 753 to descend, and enabling the baffle block 75 to have a staying position at a low position, that is, between the first card pushing position 421 and the second card pushing position 422. The pushing card motor 72 drives the second lifting wheel 772 to rotate reversely, thereby driving the rotating block 796 to rotate, driving the lifting block 753 to ascend, and enabling the baffle block 75 to have a staying position at a high position, that is, no longer between the first card pushing position 421 and the second card pushing position 422. Further preferably, a first staying surface 7963 and a second staying surface 7964 that cooperate with the baffle spring piece 797 are provided on the rotating block 796. The first staying surface 7963 and the second staying surface 7964 form a certain inclined angle. Driving the first lifting wheel 762 to rotate forward by the driving motor can drive the rotating block 796 to rotate from the second staying surface 7964 against the baffle spring piece 797 to the first staying surface 7963 against the baffle spring piece 797, so that the baffle block 75 has a staying position at a low position. Driving the second lifting wheel 772 to rotate reversely by the driving motor can drive the rotating block 796 to rotate from the first staying surface 7963 against the baffle spring piece 797 to the second staying surface 7964 against the baffle spring piece 797, so that the baffle block 75 has a staying position at a high position.

[0180] Even more preferably, a second connecting shaft 7531 is provided on the lifting block 753. The second connecting shaft 7531 is fixedly connected or integrally formed with the lifting block 753. A long hole is provided on the rotating block 796. The long hole can be a complete hole or a hole with a notch. In this embodiment, the long hole has a notch. The second connecting shaft 7531 is movably matched with the long hole. Such a setting can enable the lifting block 753 to lift in place under the drive of the rotating block 796.

[0181] Specifically, the first lifting wheel 762 and the second lifting wheel 772 are circumferentially distributed in different areas on the camshaft 792. Such arrangement is because the first baffle plate shift block 7961 and the second baffle plate shift block 7962 are respectively located at the front and rear sides of the rotating block 796 and the two rotate together. When the first lifting wheel 762 rotates forward to drive the first block plate shift block to rotate forward to drive the lifting block 753 to descend, if the first lifting wheel 762 and the second lifting wheel 772 overlap in the circumferentially distributed area on the camshaft 792, the rotation of the second block plate shift block will be hindered; and when the second lifting wheel 772 reverses to drive the second block plate shift block to reverse to drive the lifting block 753 to ascend, if the first lifting wheel 762 and the second lifting wheel 772 overlap in the circumferentially distributed area on the camshaft 792, the rotation of the first block plate shift block will be hindered.

[0182] like Figure 33 and 34 A first camshaft sleeve 712 is also fixed in the head box 71 shown, and the camshaft 792 can rotate in the first camshaft sleeve 712. A one-way bearing C798 is provided at the rear end of the first camshaft sleeve 712. The outer surface of the one-way bearing C798 is transmission-connected to the first card pushing wheel 761 and the first lifting wheel 762. The one-way bearing C798 is used to limit the reverse rotation of the first card pushing wheel 761 and the first lifting wheel 762.

[0183] Specifically, a second camshaft sleeve 713 is also fixed in the head box 71, and the camshaft 792 can rotate in the second camshaft sleeve 713. A one-way bearing D799 is sleeved on the front end of the second camshaft sleeve 713. The outer surface of the one-way bearing D799 is transmission-connected with at least the second lifting wheel 772 of the second card-pushing wheel 771 and the second lifting wheel 772. The one-way bearing D799 is used to limit the forward rotation of at least the second lifting wheel 772 of the second card-pushing wheel 771 and the second lifting wheel 772. This is set up because the card-pushing motor 72 drives the camshaft 792 to rotate forward for one circle, and the first card-pushing head 73 completes a reciprocating linear motion of pushing cards. The first card pushing wheel 761 and the first lifting wheel 762 are only matched with the camshaft 792 through a single one-way bearing A791. Then, when the camshaft 792 stops rotating, the first card pushing wheel 761 and the first lifting wheel 762 will swing back due to inertia, which may affect the first card pushing head 73 from completely returning to its original position, thereby causing a card failure and the blocking block 75 to stay in the wrong position. After the one-way bearing C798 is matched, the one-way bearing C798 does not affect the forward rotation of the first card pushing wheel 761 and the first lifting wheel 762, but can prevent the first card pushing wheel 761 and the first lifting wheel 762 from swinging back; similarly, the one-way bearing D799 is also used to at least prevent the second lifting wheel 772 of the second card pushing wheel 771 and the second lifting wheel 772 from swinging back.

[0184] More preferably, the first camshaft sleeve 712 and the second camshaft sleeve 713 may be integrally formed or may be two separate parts.

[0185] Specifically, the head box 71 is also provided with a first card-viewing light control 714 and a second card-viewing light control 715, and the first card-viewing light control 714 and the second card-viewing light control 715 are respectively located at the rear side and the front side of the first card blocking part 751; further preferably, the first card-viewing light control 714 is located below the first card pushing head 73, and the second card-viewing light control 715 is located below the second card pushing head 74.

[0186] Specifically, the head box 71 is further provided with a baffle sensor 716 , and the baffle sensor 716 is used to detect the movement of the baffle block 75 into and out of the first card pushing position 421 and the second card pushing position 422 .

[0187] It is worth noting that the baffle sensor 716, the first card viewing light control 714 and the second card viewing light control 715 can also be applied to the card pushing machine head in Example 1.

[0188] A first curve wheel 76 includes the first card pushing wheel 761 and the first lifting wheel 762 as described above. The first lifting wheel 762 and the first card pushing wheel 761 can be fixedly connected, integrally formed, or two separate parts.

[0189] A second curve wheel 77 includes the second card pushing wheel 771 and the second lifting wheel 772 as described above. The second lifting wheel 772 and the second card pushing wheel 771 can be fixedly connected, integrally formed, or two separate parts.

[0190] In this embodiment, the card pushing process of the card pushing machine head is as follows:

[0191] like Figure 28 As shown, when the card-pushing device is feeding cards, the initial position of the card-blocking block 75 is at a low position, that is, the first card-blocking portion 751 is located between the first card-pushing position 421 and the second card-pushing position 422. When the card-feeding device delivers the mahjong tile 10 to the first card-pushing position 421, the mahjong tile 10 is blocked by the first card-blocking portion 751, and the first card-viewing light control 714 located on the head box 71 senses the mahjong tile 10. Figure 29 As shown, the card pushing motor 72 rotates forward to drive the first curved wheel 76 to rotate forward, driving the first swing arm 794 to swing and causing the first card pushing head 73 to push the cards. The first card pushing head 73 pushes the single mahjong tile 10 from the first card pushing position 421 into the horizontal pushing card loading device. After the card pushing motor 72 rotates forward for one circle, the first card pushing head 73 returns to its original position, waiting for the next card pushing, and repeats this action until the horizontal pushing card loading device is full of mahjong tiles 10. During the card pushing process, since the baffle block 75 is in a low position, the first curved wheel 76 does not generate thrust on the first baffle plate block 7961 during rotation, and when the second card pushing wheel 771 in the second curved wheel 77 is fixed on the camshaft 792, the second card pushing head 74 pushes empty, and when the second card pushing wheel 771 is movably connected to the camshaft 792 through the one-way bearing B793, the second card pushing head 74 is stationary.

[0192] After the push card loading device is fully loaded, Figures 30 - 32 As shown, the card pushing motor 72 reverses to drive the second curve wheel 77 to rotate and then drives the second baffle block 7962 to rotate, so that the first stop surface 7963 on the rotating block 796 is converted from abutting against the baffle spring sheet 797 to a second stop surface 7964 abutting against the baffle spring sheet 797 and drives the lifting block 753 to rise, thereby making the card blocking block 75 move out between the first card pushing position 421 and the second card pushing position 422. During this process, the first card pushing head 73 is stationary and the second card pushing head 74 is pushed in vain.

[0193] After the card delivery device delivers the mahjong tile 10 to the second card pushing position 422, the second card viewing light control 715 senses that the mahjong tile 10 is in place. Figures 30 - 32As shown, the pushing motor 72 rotates in reverse to drive the second curve wheel 77 to rotate, thereby driving the second swing arm 795 to swing and causing the second pushing head 74 to perform pushing. The second pushing head 74 pushes a single mahjong tile 10 from the second pushing position 422 into the ramp tile-loading mechanism. After the pushing motor 72 rotates in reverse for one full circle, the second pushing head 74 returns to its original position, waiting for the next push. This action is repeated until the ramp tile-loading mechanism is full of mahjong tiles 10; during this pushing process, since the blocking block 75 is in the high position, the second curve wheel 77 does not exert a thrust on the second baffle block 7962 during rotation and the first pushing head 73 remains stationary.

[0194] After the ramp tile-loading mechanism is full of tiles, as Figure 29 and Figure 30 shown, the pushing motor 72 rotates forward to drive the first curve wheel 76 to rotate, thereby driving the first baffle block 7961 to rotate, causing the rotation block 796 to change from the second resting surface 7964 resting on the baffle spring piece 797 to the first resting surface 7963 resting on the baffle spring piece 797 and driving the lifting block 753 to descend, thereby causing the blocking block 75 to move into the space between the first pushing position 421 and the second pushing position 422 to wait for the next tile-loading.

[0195] It should be noted that the pushing head described in Embodiment 2 may also include two pushing motors 72 as in the pushing head of Embodiment 1. One pushing motor 72 is used to drive the first curve wheel 76 to rotate so that the first pushing head 73 performs pushing and the blocking block 75 has a resting position at the low position, and the other pushing motor 72 is used to drive the second curve wheel 77 to rotate so that the second pushing head 74 performs pushing and the blocking block 75 has a resting position at the high position.

[0196] A tile-picking and transporting system includes the pushing head described in Embodiment 2.

[0197] A mahjong machine includes the pushing head described in Embodiment 2.
