Technical Field

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

[0002] The current fully automatic mahjong machine can integrate functions such as shuffling and dice rolling, which provides a lot of convenience for people to play mahjong. However, the current fully automatic mahjong machine basically has only four exits, and the two-layer mahjong machine can only be raised to the table from the four exits respectively. When playing cards, it is still necessary to cut and arrange the cards manually, which is not only troublesome to operate, but also often results in wrong cutting of cards, and the cards can only be reshuffled.

[0003] In order to solve this problem, a Chinese invention patent with publication number CN109248437 discloses a card feeding mechanism of an eight-mouth fully automatic mahjong machine, the mahjong machine comprising a frame, a large plate arranged in the frame, and two exits arranged on each side of the large plate; the card feeding mechanism comprises a starting card feeding track arranged on each side of the large plate, a first card feeding track and a second card feeding track arranged on each side of the large plate, the starting ends of the first card feeding track and the second card feeding track are both connected to the corresponding starting card feeding track, and the card feeding ends of the first card feeding track and the second card feeding track are respectively arranged corresponding to the two exits on the same side of the large plate; a first card pushing head is slidably installed in the starting card feeding track and the first card feeding track, and a second card pushing head is slidably installed in the starting card feeding track and the second card feeding track; a driving structure for driving the first card pushing head and the second card pushing head to simultaneously start from the starting card feeding track and simultaneously reach their respective card feeding ends.

[0004] Although the card feeding mechanism of this patent realizes the simultaneous card feeding and card separation, thus saving the card separation time, the large plate of this patent requires two tracks on each side, two card pushing heads and two sets of driving structures for driving the card pushing heads to move, and the overall structure is relatively complex. In addition, this patent uses a wire rope to drive the card pushing head, the wire rope motor has a large load, the steel wire is prone to shaking and breaking, the card loading process is not stable enough, and the service life of the wire rope is short.

[0005] In addition, the Chinese invention patent with publication number CN101569794 discloses a double-push-and-raise mechanism for an eight-mouth automatic mahjong table, including a lift seat, a motor, a lift plate assembly, a push plate assembly and a transmission assembly, wherein the motor, lift plate assembly, push plate assembly and transmission assembly are mounted on the lift seat; the push plate assembly includes: a cylindrical cam connected to the transmission assembly and rotated under the drive of the transmission assembly; a push plate, having a push plate bearing and a push plate guide shaft, the push plate bearing is connected to the push plate guide shaft through a push plate guide sleeve, the push plate bearing is in contact with the cam circumference of the cylindrical cam, and the push plate bearing reciprocates along the push plate guide shaft under the rotation of the cylindrical cam. Although the technical solution of this patent realizes the double-push-and-raise process of the eight-mouth automatic mahjong table, the mechanism has many parts and components and the overall structure is complex.

[0058] Embodiment 1:

[0059] like Figures 1 to 5The mahjong machine shown in the figure is a mahjong machine, comprising a mahjong machine desktop 1, a frame 2, a central control panel assembly located in the center of the bottom plate of the frame 2 and a shuffling plate 3, four sets of card picking and transporting systems are arranged around the shuffling plate 3, the card picking and transporting system comprises a card feeding device 4 for picking up mahjong tiles 10 from the shuffling plate 3 one by one and sending them out, a stacking and pushing device 5 for stacking two mahjong tiles 10 into a pile and pushing them out, the card picking and transporting system also comprises a flat-pushing card loading device 6 and a slope card loading device 7 for delivering the arranged mahjong tiles 10 in multiple piles onto the mahjong machine desktop 1, four inner card outlets 11 and four outer card outlets 12 are arranged on the mahjong machine desktop 1, the four outer card outlets 12 are surrounded by a rectangular shape, the four inner card outlets 11 are surrounded by a rectangular shape and are distributed on the inner side of the outer card outlet 12, the flat-pushing card loading device 6 is installed at the outer card outlet 12 and comprises a card receiving strip 61 for storing the mahjong tiles 10 and a card receiving strip 61 for storing the mahjong tiles 10 The mahjong tiles 10 on the card strip 61 are sent to the mahjong machine table 1 by a flat push card loading drive mechanism. The slope card loading device 7 includes a card loading component and a card lifting component. The card loading component includes a card storage slot 71 for storing mahjong tiles 10, a card loading push head 72 for pushing mahjong tiles 10 along the slope and its slope card loading drive mechanism. The card lifting component is installed at the inner card outlet 11. The card lifting component includes a card lifting support plate 73 and its card lifting drive mechanism. Device 5 pushes the stacked mahjong tiles 10 into the card storage slot 71 through the card inlet of the card storage slot 71. The card storage slot 71 includes at least one arc-shaped curved portion. One end of the card storage slot 71 is a first card outlet, which is connected to the card receiving strip 61 in the horizontal push card loading device 6. The other end of the card storage slot 71 is a second card outlet, which is connected to the card lifting support plate 73 in the card loading component. The card inlet of the card storage slot 71 is arranged between the first card outlet and the second card outlet.

[0060] In this embodiment, the slope card loading drive mechanism drives the card loading push head 72 to reciprocate along the card storage slot 71 and enables it to have a first card pushing position and a second card pushing position; when storing cards, the card pushing head 51 pushes a pile of mahjong tiles 10 stacked on the card receiving table 52 into the card storage slot 71 through the card inlet of the card storage slot 71. When the card storage slot 71 has enough mahjong tiles 10, the slope card loading drive mechanism drives the card loading push head 72 to move from the first card pushing position to the second card pushing position and pushes multiple piles of mahjong tiles 10 in the card storage slot 71 onto the card receiving strip 61. The card loading push head 72 stays at the first card pushing position. In the second card pushing position, the card pushing head 51 continues to push the stacked mahjong tiles 10 into the card storage slot 71 until there are enough mahjong tiles 10 in the card storage slot 71 again; when loading cards, the card pushing motor 54 drives the card pushing head 51 to descend until the top of the card pushing head 51 is not higher than the upper surface of the card receiving table 52 or the bottom surface of the card storage slot 71, and the slope card loading drive mechanism drives the card loading pushing head 72 to move from the second card pushing position to the first card pushing position and pushes the multi-deck mahjong tiles 10 in the card storage slot 71 onto the mahjong machine table top 1, and the flat card loading device 6 pushes the mahjong tiles 10 on the card receiving strip 61 onto the mahjong machine table top 1. Further preferably, the stacking and pushing device 5 is provided with a counting device, and when the number of piles of mahjong tiles 10 on the card storage slot 71 of the slope card loading device 7 reaches a preset first value, the stacking and pushing device 5 stops stacking and pushing the cards, and the card loading drive mechanism drives the card loading push head 72 to move from the first card pushing position to the second card pushing position and pushes the multiple piles of mahjong tiles 10 in the card storage slot 71 onto the card receiving strip 61, and then the stacking and pushing device 5 starts stacking and pushing the cards again until the number of piles of mahjong tiles 10 on the card storage slot 71 reaches a preset second value, at which time the stacking and pushing device 5 stops stacking and pushing the cards.

[0061] The card feeding device 4 in one set of card picking and transporting systems is located between the card lifting assembly and the card pushing device 6 in another adjacent set of card picking and transporting systems; the specific structure of the card feeding device 4 can be found in patent documents such as publication number CN105413161A, CN106492454A, and CN106669142A; the card feeding device 4 generally includes a card feeding box, a guide plate is provided in front of the card feeding port of the card feeding box, a card feeding wheel with a magnet is provided at the card feeding port of the card feeding box, a tensioning wheel and a driving wheel are provided in the card feeding box, a card discharging wheel is provided at the card discharging port of the card feeding box, and a conveyor belt is wrapped around the card feeding wheel, the card discharging wheel and the driving wheel and is tensioned by the tensioning wheel. The card feeding port is provided with a card guide groove, the width of the card feeding port is slightly larger than the width of the selected mahjong tiles 10 and shorter than the length of the mahjong tiles 10, and the height of the card feeding port is larger than the thickness of the mahjong tiles 10 and smaller than the width of the mahjong tiles 10. One, two, three or four magnets are embedded in the card feeding wheel. The portion of the outer circumferential surface of the card feeding wheel opposite to the magnet is designed as a plane corresponding to the size of the mahjong tiles 10. The mahjong tiles 10 are uniformly facing downward after the rotation of the card feeding wheel, and are uniformly fed in the length direction of the mahjong tiles 10 after passing through the card guide groove. The running path of the mahjong tiles 10 in the card feeding device 4 is a card feeding channel, which starts from the card feeding port of the card feeding box and ends at the card outlet of the card feeding box.

[0062] like Figure 6 , Figure 7 and Figure 8 As shown, the stacking and pushing device 5 includes a card pushing head 51 and a card receiving platform 52, the card receiving platform 52 is connected to the card outlet of the card feeding device 4 and is slightly lower than the card outlet of the card feeding device 4, the card pushing head 51 and the card inlet of the card storage slot 71 are respectively located on the opposite sides of the card receiving platform 52, the card receiving platform 52 and the card pushing head 72 are respectively located on both sides of the card pushing head 51, when the card receiving platform 52 receives the first mahjong tile 10 delivered by the card feeding device 4, then the card receiving platform 52 descends and makes the upper surface of the mahjong tile 10 on the card receiving platform 52 not higher than the card outlet of the card feeding channel, then the card receiving platform 52 receives the second mahjong tile 10 delivered by the card feeding device 4 and stacks them into a pile, and the card pushing head 51 pushes the stacked mahjong tiles 10 on the card receiving platform 52 onto the card storage slot 71.

[0063] Among them, the first way for the card pushing head 51 to push the mahjong tiles 10 on the card receiving platform 52 to the card storage slot 71 is: when a pile of tiles is stacked on the card receiving platform 52, the card receiving platform 52 rises to the initial position, and then the card pushing head 51 pushes the mahjong tiles 10 to the card storage slot 71, and then the card receiving platform 52 waits for the next round of stacking tiles.

[0064] The second way in which the pusher 51 pushes the mahjong tiles 10 on the card receiving platform 52 onto the card storage slot 71 is: when a pile of tiles is stacked on the card receiving platform 52, the pusher 51 directly pushes the mahjong tiles 10 onto the card storage slot 71, and then the card receiving platform 52 rises to the initial position to wait for the next round of stacking.

[0065] In the embodiment of the present application, the card pushing head 51 uses the first method to push the mahjong tiles 10 on the card receiving table 52 onto the card storage slot 71.

[0066] like Figure 2-5 As shown, the push-up card loading device 6 and the card-lifting assembly in the card picking and transporting system in the same group are both located on the adjacent two sides of the shuffling plate 3, the card-lifting assembly is located on the inner side of the push-up card loading device 6, and the card-discharging direction of the first card-discharging port of the card storage slot 71 is rotated at an angle greater than 45° and not greater than 135° in the clockwise direction compared to the card-discharging direction of the second card-discharging port; further preferably, the card-discharging direction of the first card-discharging port of the card storage slot 71 is rotated at an angle greater than 75° and not greater than 105° in the clockwise direction compared to the card-discharging direction of the second card-discharging port.

[0067] In other embodiments, the push-up card loading device 6 and the card-lifting assembly in the same group of card picking and transporting systems can also be respectively located on the same side of the shuffling plate 3, and the card-lifting assembly is located on the inner side of the push-up card loading device 6, and the card-discharging direction of the first card outlet of the card storage slot 71 is rotated by an angle of no more than 45° in the clockwise or counterclockwise direction compared to the card-discharging direction of the second card outlet; further preferably, the card-discharging direction of the first card outlet of the card storage slot 71 is rotated by an angle of no more than 15° in the clockwise or counterclockwise direction compared to the card-discharging direction of the second card outlet.

[0068] In this embodiment, the slope card-loading device 7 also includes a card-lifting component. The specific structure of the card-lifting component can be found in patent documents with publication numbers CN201906453U, CN201949619U, CN102133480A, CN103861280A and CN204699375U. Generally speaking, one party's card-lifting component includes a card-lifting bracket, a card-lifting support plate 73 and a card-lifting motor. The card-lifting bracket is provided with a card-lifting slot, the card-lifting support plate 73 is located at the upper part of the card-lifting slot, and one end of the card-lifting support plate 73 is installed on the card-lifting slot, and the other end of the card-lifting support plate 73 can move and is driven up and down by the card-lifting motor through a transmission mechanism such as a cam or a card-lifting rocker arm. The card-lifting bracket is also provided with a sensor C for detecting the position of the card-lifting support plate 73, for example, two upper and lower Hall elements or photocells.

[0069] When the movable end of the card lifting support plate 73 descends, the movable end of the card lifting support plate 73 is connected to the card storage slot 71. At this time, the card storage slot 71, the card receiving platform 52 and the card lifting support plate 73 together form an inclined card loading channel for mahjong tiles 10, and the card pushing head 51 can be moved in and out of the inclined card loading channel; this is arranged because before the card storage slot 71 and the card receiving strip 61 are full of mahjong tiles 10, the card pushing head 51 needs to push the mahjong tiles 10 toward the card storage slot 71 and onto the card receiving strip 61 along the card storage slot 71, so the card pushing head 51 is located in the inclined card loading channel, when the card storage slot 71 and the card receiving strip 61 are full of mahjong tiles 10, the inclined card loading device 7 pushes the mahjong tiles 10 in the card storage slot 71 onto the tabletop, if the card pushing head 51 is located in the inclined card loading channel, it will block the passage of the mahjong tiles 10, so the card pushing head 51 is no longer located in the inclined card loading channel.

[0070] The first way for the pusher 51 to move out of or into the sloped card loading passage is that when there are enough mahjong tiles 10 in the card storage slot 71 and on the card receiving strip 61, the pusher 51 rises or falls relative to the sloped card loading passage.

[0071] The second way for the pusher head 51 to move out of or into the sloped card loading passage is that when there are enough mahjong tiles 10 in the card storage slot 71 and on the card receiving strip 61, the pusher head 51 moves horizontally to the left or to the right relative to the sloped card loading passage.

The wire rope is connected to the active reel after winding through multiple guide wheels and the card storage slot 71. The card loading push head 72 is fixed on the wire rope. When the first card loading motor moves the wire rope through the active reel, the card loading push head 72 moves on the card loading track, thereby driving the card loading push head 72 to move from the first card pushing position to the second card pushing position and push the mahjong tiles 10 in the card storage slot 71 onto the card receiving strip 61, and driving the card loading push head 72 to move from the second card pushing position to the first card pushing position and push the mahjong tiles 10 in the card storage slot 71 onto the card lifting support plate 73.
