Description

Technical Field

[0001] The invention belongs to the field of mahjong entertainment equipment, relates to a mahjong machine, and in particular to a card-raising device for raising card piles, a card-loading mechanism containing the card-raising device, and a mahjong machine. Background Art

[0002] A mahjong machine usually has a shuffling mechanism for shuffling mahjong tiles, a loading mechanism for stacking the shuffled tiles and placing them on a table for use, an operating panel mechanism for a user to input operating instructions, and a table frame mechanism for overall support.

[0003] Among them, the card loading mechanism needs to be set up corresponding to each user. For example, a common mahjong machine is used by four users, so four sets of card loading mechanisms need to be set up; in this case, each set of card loading mechanisms also needs to realize functions such as stacking cards, storing cards, pushing cards, and raising cards, so its layout space is relatively limited and the structural design needs to be very compact.

[0004] In some prior art mahjong machines, a card-lifting device is provided in the card-loading mechanism to lift the pile of cards to the table. For example, CN111991798A discloses a fully automatic mahjong machine, whose card-lifting assembly includes a lifting swing arm and a lifting push rod, wherein the lifting push rod drives the lifting swing arm to swing, and the lifting swing arm drives the card-loading seat carrying the pile of cards to rotate through the shifting block to load the cards. In such a card-lifting assembly, because the lifting push rod relies on the intermittent gear system drive to achieve reciprocating motion, and the start or end of the lifting action depends on the intermittent gear matching, it is impossible to achieve precise automatic process control.

[0005] In particular, if the user wishes to use different card-loading modes (for example, he wishes to load the starting hand and the cards to be taken at one time, or wishes to load the starting hand and the cards to be taken twice), the lifting and lowering action needs to be performed accurately (start, pause or end) according to the different modes and the action states of other components. However, the existing card-lifting device cannot perform such precise action control. Therefore, in fact, the aforementioned different card-loading modes cannot be realized. Summary of the invention

[0047] <Example>

[0048] Figure 1is a block diagram of a mahjong machine according to an embodiment of the present invention, Figure 2 is a structural diagram of a mahjong machine from an angle according to an embodiment of the present invention, Figure 3 It is a structural diagram of a mahjong machine according to an embodiment of the present invention with a part of the structure omitted.

[0049] like Figure 1-3 As shown, this embodiment provides a mahjong machine 100 for automatically shuffling and loading mahjong tiles 200, including a loading mechanism 101, an operating disk mechanism 102, a table frame mechanism 103, a shuffling mechanism 107 and a control device 108.

[0050] The table frame mechanism 103 includes an outer frame 104, a table top 105 mounted on the outer frame 104, and a lower frame 106 for supporting the table top 105 and other mechanisms. The bottom of the lower frame 106 is provided with table legs ( Figure 2 , Figure 3 The table legs are omitted. Figure 2 The outer frame 104, the lower frame 106, the table top 105 and the shuffling mechanism 107 are further omitted).

[0051] The operation disk mechanism 102 is arranged in the middle of the table top 105, and an operation disk 1021 is arranged on the top thereof. The operation disk 1021 is provided with a plurality of different operation buttons (not shown in the figure) for the user to input operation instructions. In this embodiment, the operation disk mechanism 102 is also provided with a lifting assembly, which can lower the operation disk 1021 under the control of the control device 108 to expose the gap between the operation disk 1021 and the table top 105, and the user can push the used mahjong tiles 200 into the gap to shuffle the tiles.

[0052] The shuffling mechanism 107 is disposed below the operating panel 1021, and is used to receive used mahjong tiles 200 and shuffle them. It includes a shuffling plate for carrying and rotating the mahjong tiles and a driving motor for driving the shuffling plate to rotate. Its specific structure and function are the same as those of the prior art and will not be described in detail herein.

[0053] The mahjong machine 100 of this embodiment can be used by four users at the same time, and accordingly, four card loading mechanisms 101 are provided, which are respectively located at the four corners of the lower frame 106 .

[0054] The control device 108 is used to control the operation of each component of the mahjong machine 100 according to the operation instructions input by the user. The control device 108 can be a chip or an industrial computer or a microcomputer with a predetermined control program, and is connected to the operating panel mechanism 102 and each controlled component and sensor of the mahjong machine 100. In addition, in this embodiment, each control unit described below can include a control program integrated in the control device 108, or can include a control program set in a separate chip, which is electrically connected or communicatively connected to the control device 108; at the same time, each control unit can also be provided with an appropriate signal transmission or control circuit structure to realize the reception of sensor signals and the control of controlled components.

[0055] Figure 4 This is a structural diagram of a card loading mechanism from one angle according to an embodiment of the present invention. Figure 5 It is a structural diagram from another angle of the card loading mechanism of an embodiment of the present invention.

[0056] like Figure 1-5 As shown, the card loading mechanism 101 includes a card supply device 10 , a card stacking device 20 , a card storage device 30 , a card pushing device 40 and a card raising device 50 .

[0057] Figure 6 It is a structural diagram of a card supply device according to an embodiment of the present invention.

[0058] like Figure 4-6 As shown, the card supply device 10 is used to absorb mahjong cards from the shuffling mechanism and supply the cards, and includes a card suction wheel 11, a card supply rack 12, a belt assembly 13 and a card supply motor 14.

[0059] Among them, the card supply rack 12 is fixedly installed on the lower frame 106, located near the shuffling mechanism 101, and has an opening facing the shuffling plate of the shuffling mechanism 101. The card suction wheel 11 is rotatably installed at the opening. The output end of the card supply motor 14 is connected to the card suction wheel 11, and can drive the card suction wheel 11 to rotate under the control of the control device 108.

[0060] The belt assembly 13 includes a card supply belt 15 wound around the card suction wheel 11, a guide wheel 16 for guiding the card supply belt 15, and a tensioning wheel 17 for tensioning the card supply belt 15. The guide wheel 16 is installed near the card stacking device 20 so that the card supply belt 15 can transport the mahjong cards thereon to the card stacking device 20.

[0061] In this embodiment, a plurality of card-attracting magnets are installed on the card-attracting wheel 11, and the mahjong tiles 200 are all inlaid with magnetic materials that can be mutually attracted to the shuffling magnets. When the card-attracting wheel 11 rotates under the drive of the card-supplying motor 14, the card-attracting magnets rotated to the downward position can absorb the mahjong tiles 200 below, and the mahjong tiles 200 are driven to the top of the card-attracting wheel 11 as the card-attracting wheel 11 continues to rotate, and then are transported to the stacking device 20 by the card-supplying belt 15.

[0062] Figure 7 is a structural block diagram of a card stacking device according to an embodiment of the present invention, Figure 8 1 is a structural diagram of a card stacking device according to an embodiment of the present invention, Fig. 9 It is a structural diagram of the card stacking device of an embodiment of the present invention after omitting the card stacking housing and the card stacking motor.

[0063] like Figure 4-5 As shown in , 7-9, the card stacking device 20 is used to stack single mahjong tiles supplied by the card supply device 10 to form a pile of tiles with two tiles stacked together, including a card stacking unit, a card shifting unit, a card stacking control unit 291 and a card stacking sensing component, wherein the card stacking sensing component includes a card stacking counting sensor 29.

[0064] The stacking unit includes a stacking block 21, a stacking block driving rod 22, a stacking driving wheel 23 and a stacking motor 24, and the card shifting unit includes a card shifting block 25, a card shifting connecting rod 26 and a card shifting driving block 27. In addition, the stacking device 20 also has a stacking housing 28 for accommodating and supporting the stacking unit and the components in the card shifting unit.

[0065] The top of the stacking block 21 is a plane, which is located near the guide wheel 16 of the card supply belt 15 in the initial state, and can receive the mahjong tiles conveyed by the card supply belt 15. The stacking block 21 is also provided with a stacking block slot 211, and one end of the stacking block driving rod 22 is a movable end, which is slidably engaged in the stacking block slot 211 through a slider.

[0066] like Fig. 9 As shown, the stacking driving wheel 23 is mounted on the output shaft of the stacking motor 24 and rotates under the drive of the stacking motor 24. A stacking driving groove 231 is provided on one side of the stacking motor 23. The stacking motor 24 receives the stacking control signal sent by the stacking control unit 291, and operates and drives the rotation of the stacking driving wheel 23 according to the stacking control signal.

[0067] The other end of the stacking block driving rod 22 is a fixed end, which has a stacking block driving shaft 221 hinged on the stacking block housing 27; the middle part of the stacking block driving rod 22 is also provided with a slider slidably engaged in the stacking block driving groove 231. When the stacking block driving wheel 23 rotates, the stacking block driving rod 22 swings up and down, and drives the stacking block 21 to move up and down through its movable end.

[0068] Fig.10 It is a structural diagram of one side of a card stacking block according to an embodiment of the present invention.

[0069] like Fig.10 As shown, the stacking driving groove 231 is approximately annular in shape, and has an inner concave section 231A with a reduced radius and an outer convex section 231B with an increased radius. When the slider in the middle of the stacking block driving rod 22 is in the inner concave section 231A, the top plane of the stacking block 21 is lower than the upper plane of the end of the card supply belt 15, and the height difference is slightly greater than the thickness of two mahjong tiles, so that the mahjong tiles transported by the card supply belt 15 can be stacked and fall on the top plane of the stacking block 21; when the slider in the middle of the stacking block driving rod 22 runs to the outer convex section 231B, it can drive the stacking block 21 to move slightly upward as a whole, so that the card shifting block 25 can perform the card shifting action.

[0070] like Figure 8-9 As shown, the card-shifting block 25 is fixed on the top of the card-shifting connecting rod 26. The card-shifting connecting rod 26 is bent in an approximately L-shaped shape, and its lower end is fixed on a side of the card-shifting driving block 27.

[0071] Fig.11 4 is a structural diagram of a shift block driving block according to an embodiment of the present invention.

[0072] like Figure 8-9 As shown in Figures 11, an arc-shaped card-digging slot 271 is provided on the other side of the card-digging driving block 27, and a slider slidably engaged in the card-digging slot 271 is provided on the other side of the card-stacking driving wheel 23 (i.e., the side opposite to the side where the card-stacking block slot 211 is located); as the card-stacking driving wheel 23 rotates, under the action of the slider and the card-digging slot 271, the card-digging driving block 27 intermittently moves back and forth and drives the card-digging block 25 to move back and forth through the card-digging connecting rod 26, so that when the two mahjong tiles 200 on the top of the card-stacking block 21 overlap to form a pile of tiles, the pile of tiles is moved toward the card storage device 30.

[0073] like Figure 8-9 As shown, the stack card counting sensor 29 is arranged near the stacking block 21, and can be installed on the card slot-related components of the card storage device 30, or can be installed by a separate mounting bracket. The stack card counting sensor 29 is a magnetic induction sensor, which can generate an induction signal when the mahjong tiles 200 with a magnet embedded therein pass through, thereby counting the mahjong tiles 200 stacked and entering the card storage device 30. Since two mahjong tiles 200 are stacked to form a pile, the total number of mahjong tiles 200 counted according to the induction signal of the stack card counting sensor 29 is divided by 2, and the number of piles of mahjong tiles 200 can be known at the same time.

[0074] Fig.12 It is a structural diagram of a card storage device according to an embodiment of the present invention.

[0075] like Fig.12 As shown, the card storage device 30 is used to store card piles, and includes a card storage tray 31, an upper slot plate 32, a lower slot plate 33, an inner slot plate 34, and a card storage sensing component.

[0076] The card storage tray 31 is generally in a square shape, with one corner being notched and the other three corners being arc-shaped, with a retaining wall 311 extending vertically upward at the edge, and a protrusion in the middle, so that a groove is formed between the retaining wall 311 and the protrusion in the middle, i.e., a card slot 312. In addition, a support 313 is further provided at the bottom of the card storage tray 31, and the card storage tray 31 is mounted on the lower frame 106 through the support 313.

[0077] The upper slot plate 32 is a plate-like component that matches the shape of the baffle wall 311 and is embedded in the upper part of the inner surface of the baffle wall 311 (equivalent to the outer side surface of the card slot 312); the lower slot plate 33 is a plate-like component that matches the card slot 312 and is embedded in the bottom surface of the card slot 312; the inner slot plate 34 is approximately annular and is adapted to the middle protrusion of the card storage tray 31, and is installed on the outer edge of the middle protrusion of the card storage tray 31 (equivalent to the inner side surface of the card slot 312).

[0078] Fig.13 This is a structural diagram of the card storage device, the card stacking device, and the card supply device in an embodiment of the present invention. Fig.13 In order to show the coordination relationship between the components, some components of the card storage device, the card stacking device and the card supply device are omitted.

[0079] like Figure 4-5 As shown in Figures 1 and 13, the card supply device 10 and the card stacking device 20 are located at the corner of the notch of the card storage tray 31 and are arranged close to one end of the card slot 312, wherein the card stacking block 21 is located at the end opening of the card slot 312. When the card block 25 is used to push the card pile toward the card storage device 30, the card pile will enter the card slot from the end opening of the card slot 312; when the next card pile is stacked and pushed toward the card slot 312 by the card block 25, the card pile will also push the card pile that has entered the card slot 312, and so on, a certain number of card piles can be stored in the card slot 312.

[0080] Fig.14 It is a cross-sectional structural diagram of a card slot according to an embodiment of the present invention.

[0081] like Fig.14As shown, the upper slot plate 32, the lower slot plate 33 and the inner slot plate 34 are all adapted to the card slot 312, and together constitute a card storage slot structure that can store and allow the card piles to pass. Among them, the bottom end of the upper slot plate 32 has a flange 321 protruding toward the center direction of the card slot 312, and the upper half of the inner slot plate 34 protrudes outward, so that two parts with different upper and lower movement radii (i.e., distances relative to the center of the card storage plate 31) are formed in the card slot 312, namely, the upper card slot 312A and the lower card slot 312B (as shown in the dotted box). The upper card slot 312A and the lower card slot 312B correspond to the upper and lower mahjong tiles in the card pile, respectively. Since the movement radius of the upper card slot 312A is larger, the mahjong tiles on the upper layer will slightly lag behind the mahjong tiles on the lower layer during the movement in the card slot 312.

[0082] The card storage sensing component includes a card storage sensor 35 disposed at the end of the card slot 312 (i.e., near the card lifting device 50). The card storage sensor 35 is a magnetic induction sensor. When there is a card pile at the end of the card slot 312, the magnet in the mahjong tile 200 is sensed to generate a corresponding induction signal.

[0083] Fig.15 is a structural block diagram of a card pushing device according to an embodiment of the present invention, Fig.16 1 is a structural diagram of a card pushing device according to an embodiment of the present invention from one angle. Fig.17 It is a structural diagram of the card pushing device from another angle.

[0084] like Figure 4-5 As shown in Figures 15-17, the card pushing device 40 is used to push and transport the card pile stored in the card storage device 30, and includes a card pushing seat 41, a card pushing rotating seat 42, a card pushing arm 43, a card pushing motor 44, a card pushing active gear 45, a card pushing sensing component 46 and a card pushing control unit 47, wherein the card pushing sensing component includes a first card pushing sensor 461, a second card pushing sensor 462 and a card pushing sensing trigger.

[0085] The card pusher 41 is fixedly mounted in the middle of the card storage tray 31, with a circular notch 41A in the middle and a circle of rotation groove 411 around the periphery. The shape and contour of the rotation groove 411 are basically matched with the card loading groove 312A, but the size is smaller, and there is a concave section 412 near the notch of the card storage tray 31.

[0086] The card pushing rotating seat 42 is rotatably mounted on the card storage tray 31 via a rotating shaft 310, and is entirely located in the notch 41A, with the upper surface exposed from the notch 41A. A push arm mounting protrusion 421 is provided on the upper surface of the card pushing rotating seat 42, and a push arm mounting hole 422 extending through the push arm mounting protrusion 421 in the horizontal direction is provided.

[0087] One end of the pusher arm 43 is movably mounted in the pusher arm mounting hole 422, and the other end is provided with a pusher head 431 for pushing the tiles in the tile slot 321. The lower end of the pusher head 431 is provided with a pusher protrusion 433 extending along the pusher direction, which can push the lower layer of mahjong tiles further forward, and in combination with the structural design of the larger movement radius of the upper tile slot 312A, the upper layer of mahjong tiles can always be slightly behind the lower layer of mahjong tiles.

[0088] When the pile of tiles reaches the tile lifting device 50, the friction between the upper tiles is small because they only touch the lower tiles. After the thrust of the tile pushing head 431 is removed, it is usually easy to slide forward a short distance. In this embodiment, the two structural designs of the tile pushing protrusion 433 and the larger movement radius of the tile loading slot 312A are coordinated to keep the upper tiles slightly behind during the movement. After the thrust is removed, the upper tiles slide this short distance and overlap just above the lower tiles, so that the tiles can be stacked neatly when loading.

[0089] The card pushing arm 43 is also provided with a card pushing slider 432 located near the card pushing head 431 , and the card pushing slider 432 is slidably embedded in the rotating groove 411 .

[0090] The card pushing motor 44 is arranged below the card pushing seat 41, and a card pushing driving gear 45 is installed on its output shaft. The lower surface of the card pushing rotating seat 42 is provided with a rotating seat tooth 423 meshing with the card pushing driving gear 45, so that the card pushing motor 44 can drive the card pushing rotating seat 42 to rotate. When the card pushing rotating seat 42 rotates, the card pushing slider 432 also moves in the rotating groove 411 accordingly, driving the card pushing head 431 to push the card pile in the card groove 321. Since the rotating groove 411 has a concave section 412, when the card pushing slider 432 reaches the position of the concave section 412, the distance between the card pushing slider 432 and the rotation center (i.e., the rotation axis 310) of the card pushing rotating seat 42 will be shortened, so that the card pushing head 431 shrinks inwardly toward the rotation center direction without contacting with the components of the card supply device 10 and the card stacking device 20, thereby avoiding mutual interference.

[0091] The first card push sensor 461 and the second card push sensor 462 are both magnetic induction sensors, which are installed below the card push rotating seat 42 and are located on the same circumference of the card push rotating seat 42. The lower surface of the card push rotating seat 42 is also provided with a card push sensing trigger member located on the same circumference as the first card push sensor 461 and the second card push sensor 462 in the vertical direction. The card push sensing trigger member is a magnet. When the card push sensing trigger member moves to the top of the first card push sensor 461 or the second card push sensor 462 as the card push rotating seat 42 rotates, the first card push sensor 461 or the second card push sensor 462 can sense the card push sensing trigger member and generate a corresponding sensing signal.

[0092] Driven by the card pushing rotating seat 42, the card pushing head 431 rotates roughly in the card slot 312 along the circumferential direction. When the card stacking device 20 is about to be reached, it is usually necessary to wait for the card stacking action to be completed (i.e., reaching the predetermined card pile number) before continuing to move forward, starting to contact the card pile from the card slot 312 at the front position of the card stacking block 21, and pushing the cards. In this process, the position where the card pushing head 431 is about to reach the card stacking device 20 and wait for the card stacking action to be completed is the card stacking entrance waiting position. In addition, after the card pushing head 431 pushes all the card piles that need to be put on the cards to the card raising device 50 along the card slot 312, it is usually necessary to wait in situ for the card raising device 50 to complete the card raising, and the position at this stage is the card raising entrance waiting position.

[0093] In the present embodiment, the first card pushing sensor 461 is arranged corresponding to the card stacking entrance waiting position of the card pushing head 431. When the card pushing rotating seat 42 rotates to the point where the first card pushing sensor 461 senses the card pushing sensing trigger (that is, the card pushing sensing trigger is approximately located directly above the first card pushing sensor 461), the card pushing head 431 just reaches the card stacking entrance waiting position; when the card pushing rotating seat 42 rotates to the point where the second card pushing sensor 462 senses the card pushing sensing trigger, the card pushing head 431 just reaches the card raising entrance waiting position.

[0094] The card pushing control unit 47 controls the operation of the card pushing motor 44 according to the sensing signals of the first card pushing sensor 461 and the second card pushing sensor 462, so that the card pushing head 431 can push all the predetermined card piles from the card slot 312 to the card lifting device 50 when pushing cards is needed.

[0095] Fig.18 is a structural block diagram of a brand-raising device according to an embodiment of the present invention, Fig.19 1 is a structural diagram of a brand-raising device according to an embodiment of the present invention. Fig. 20 It is a structural diagram of the card lifting device of an embodiment of the present invention after omitting the supporting frame.

[0096] like Figure 3-5 As shown in 18-20, the card lifting device 50 is used to lift the pile of cards pushed by the card pushing device 40 to the table top, and includes a bearing unit, a swing unit and a card lifting control unit 501, wherein the bearing unit includes a bearing frame 51, a bearing plate 52 and a bearing sensor 502, and the swing unit includes a swing motor 53, a swing arm 54, a swing connecting rod 55, a swing gear set composed of a swing driving wheel 56 and a swing driven wheel 57, and a swing sensing component 60.

[0097] The carrier frame 51 is fixedly mounted on the lower frame 106, and is located near the card supply frame 12 and is fixedly connected to the card supply frame 12 to form a frame body. An opening is formed at the lower end of one side of the carrier frame 51 to facilitate the exposure of the card suction wheel 11, and a bearing groove 511 is formed at the upper end. The bearing groove 511 has an open end 511A, and its opening faces the rear end of the card slot 312, and the depth of the bearing groove 511 gradually increases from the other end to the open end 511A.

[0098] The carrying plate 52 is used to carry the pile of cards to be loaded. The carrying plate 52 is a long strip-shaped plate-like member, one end of which is a receiving end that can receive the pile of cards pushed by the pushing arm 43 from the card slot 312, and is located at the open end 511A; the other end is a mounting end, which is rotatably mounted on the other end of the carrying slot 511 relative to the open end 511A through a rotating shaft, so that the carrying plate 52 can swing up and down in the carrying slot 511, and accordingly, its receiving end can rise or fall at the open end 511A.

[0099] In this embodiment, a bearing sensor 502 is provided at the edge of the receiving end of the bearing plate 52, and the bearing sensor 502 is a magnetic induction sensor. When the pushing arm 43 pushes the card pile in the card slot 312 onto the bearing plate 52, the bearing sensor 502 can sense the magnet in the mahjong tile, thereby generating a corresponding induction signal; when the card at the edge of the receiving end is taken away, the bearing sensor 502 can no longer sense the magnet in the mahjong tile, and no longer generates a corresponding induction signal.

[0100] Since the pile of cards pushed by the card pushing arm 43 is usually distributed from the edge of the receiving end to the installation end, and the cards at the edge of the receiving end are usually taken away last, therefore, the bearing sensor 502 cannot sense the mahjong cards, which means that all the mahjong cards on the bearing plate 52 have been taken away, and the next card raising action can be prepared.

[0101] The table top 105 is provided with a card output slot 105A corresponding to the position and matching the shape of the supporting plate 52. When the supporting plate 52 swings upward until the receiving end rises to the highest position, the supporting plate 52 as a whole is exposed from the table top at the card output slot 105, and the user can take away the card pile on the supporting plate 52. The position of the supporting plate 52 in this state is referred to as the upper swing position of the supporting plate 52 hereinafter; when the supporting plate 52 swings downward until the receiving end drops to the lowest position, the receiving end is basically flush with the bottom of the card slot 312, and the card pushing arm 43 can push the card pile in the card slot 312 from the receiving end to the supporting plate 52. The position of the supporting plate 52 in this state is referred to as the lower swing position of the supporting plate 52 hereinafter.

[0102] The swing motor 53 is installed below the card storage tray 31 , and its output shaft extends upward to above the card storage tray 31 .

[0103] The swing driving wheel 56 is installed on the output shaft of the swing motor 53 and can rotate under the drive of the swing motor 53 .

[0104] A driven wheel groove 314 is provided on the card storage tray 31 near the swing driving wheel 56. The swing driven wheel 57 is rotatably installed in the driven wheel groove 314 through a driven wheel shaft 316. It is meshed with the swing driving wheel 56 and can be driven by the swing driving wheel 56 to rotate under the drive of the swing motor 53.

[0105] Fig.21 It is a structural diagram of one side surface of the driven wheel of an embodiment of the present invention.

[0106] like Figure 19-21 As shown, a track groove 572 is provided on one side surface of the swinging driven wheel 57. The track groove 572 is in a shape of protruding on one side, and the far end 572A is farthest from the center of the swinging driven wheel 57 (the rotation center, that is, the center of the driven wheel shaft 316), and the proximal end 572B is closest to the center of the swinging driven wheel 57.

[0107] Fig. 22 It is a structural diagram of the swing connecting rod of the present invention.

[0108] like Figure 19-20 As shown in Figures 22, both ends of the swing link 55 each have an end portion in the shape of a straight rod, one of which is a driven wheel mating end 551 that cooperates with the swing driven wheel 57, and the other end is a swing mating end 552 that cooperates with the swing arm 54. In this embodiment, the length directions of the driven wheel mating end 551 and the swing mating end 552 are parallel to each other.

[0109] A straight connecting rod matching groove 315 whose size matches the driven wheel matching end 551 is provided in the driven wheel groove 314 . The driven wheel matching end 551 is located in the connecting rod matching groove 315 , so that the driven wheel matching end 551 is roughly located below the swinging driven wheel 57 .

[0110] The surface of the side where the track groove 572 of the swing driven wheel 57 is located faces downward, and a roller 553 is also provided on the upper surface of the driven wheel mating end 551. The roller 553 is slidably embedded in the track groove 572, so that when the swing driven wheel 57 rotates, the swing connecting rod 55 can be driven by the roller 553 to reciprocate along the length direction of the connecting rod mating groove 315.

[0111] like Fig. 20 As shown, a swing shaft portion 541 is provided at the lower end of the swing arm 54 , and the swing shaft portion 541 is penetrated and arranged on the supporting frame 51 , so that the swing arm 54 can rotate around the swing shaft portion 541 and swing up and down.

[0112] The end of the swing shaft portion 541 exposed on the outside of the carrier frame 51 is provided with swing shaft teeth 542 distributed along the circumferential direction, and the swing matching end 552 is provided with swing matching teeth 554 distributed along the length direction. The swing shaft teeth 542 and the swing matching teeth 554 are meshed with each other. When the swing link 55 reciprocates and translates, it can drive the swing arm 54 to swing up and down.

[0113] A bearing matching groove 521 is provided on the lower surface of the receiving end of the bearing plate 52, and a swinging slider 543 is provided on the upper end of the swinging arm 54 to be slidably matched in the bearing matching groove 521. When the swinging arm 54 swings up and down driven by the swinging link 55, the receiving end of the bearing plate 52 can be driven to swing up and down, that is, to swing back and forth between the upper swinging position and the lower swinging position.

[0114] Since the distal end 572A and the proximal end 572B of the track groove 572 correspond to the two ends of the reciprocating translation stroke of the swing link 55 respectively, when the roller 553 moves toward the distal end 572A, the swing arm 54 will rotate in the direction away from the swing link 55, and vice versa.

[0115] In the present invention, the relative positions of the swing link 55 and the swing arm 54 can be changed according to the different meshing states of the swing shaft teeth 542 and the swing matching teeth 554, so the movement of the swing link 55 can correspond to the different lifting and lowering movements of the swing arm 54, as follows:

[0116] When the swing link 55 is in a retracted state (i.e., the roller 553 is located at the proximal end 572B and the swing link 55 is located closer to the swing driven wheel 57), and the swing arm 54 is facing upward, the rotational movement of the swing arm 54 away from the swing link 55 will cause its upper end to move downward; when the swing link 55 is in a retracted state and the swing arm 54 is toward the swing link 55 (at this time the swing arm 54 is in an approximately horizontal state), the rotational movement of the swing arm 54 away from the swing link 55 will cause its upper end to move upward.

[0117] Therefore, the distal end 572A of the track groove 572 corresponds to one of the upper swing position and the lower swing position of the supporting plate 52, while the proximal end 572B corresponds to the other one of the upper swing position and the lower swing position.

[0118] In this embodiment, the former situation (i.e. the situation where the swing link 55 is in a retracted state and the swing arm 54 is in a vertical state) is taken as an example for specific description.

[0119] Fig.23 It is a structural diagram of the other side surface of the driven wheel of an embodiment of the present invention.

[0120] like Figure 19-20As shown in FIGS. 23 and 23 , the other side surface (i.e. the upward surface) of the swing driven wheel 57 is provided with a first swing sensing portion 58 and a second swing sensing portion 59 .

[0121] Fig.23 In the figure, different circumferences of the swing driven wheel 57 are shown in the form of dotted circles. Fig.19 As shown, with the center of the driven wheel shaft 316 as the center of the circle, the first swing sensing portion 58 and the second swing sensing portion 59 are distributed on both sides of the driven wheel shaft 316, and the two are located on the same diameter of the swinging driven wheel 57, but are located on different circumferences of the swinging driven wheel 57 (that is, the distances between the two and the rotation center of the swinging driven wheel 57 are different).

[0122] In addition, the distal end 572A and the proximal end 572B of the present embodiment are also on the same diameter line of the swing driven wheel 57 .

[0123] The swing sensing assembly 60 includes a first swing sensor 61 matched with the first swing sensing portion 58 and a second swing sensor 62 matched with the second sensing portion 58 .

[0124] In this embodiment, the first swing sensing portion 58 and the second swing sensing portion 59 are both magnets, and the first swing sensor 61 and the second swing sensor 62 are both magnetic induction sensors.

[0125] In this embodiment, the first swing sensor 61 and the second swing sensor 62 are both arranged at specific positions, so that when the roller 553 reaches the proximal end 572B, the first swing sensing portion 58 just reaches below the first swing sensor 61, and when the roller 553 reaches the distal end 572A, the second swing sensing portion 59 just reaches below the second swing sensor 62.

[0126] Thus, when the roller 553 reaches the proximal end 572B, so that when the swing arm 54 is in a vertical state and the supporting plate 52 is in an upper swing position, the first swing sensor 61 just senses the first swing sensing part 58 and outputs a sensing signal; when the roller 553 reaches the distal end 572A, so that when the swing arm 54 swings from a vertical state to a horizontal state and the supporting plate 52 is in a lower swing position, the second swing sensor 62 just senses the second swing sensing part 59 and outputs a sensing signal.

[0127] In addition, when the roller 553 is neither at the proximal end 572B nor at the distal end 572A, the first swing sensor 61 and the second swing sensor 62 do not output a sensing signal, indicating that the supporting plate 52 is at a position between the upper swing position and the lower swing position.

[0128] Therefore, the first swing sensing portion 58 of the present embodiment corresponds to the upper swing position of the carrier plate 52, and the second swing sensing portion 59 corresponds to the lower swing position of the carrier plate 52. Through the sensing signals outputted in real time by the first swing sensor 61 and the second swing sensor 62, it can be accurately determined whether the current carrier plate 52 is in the lower swing position, the upper swing position, or between the two positions.

[0129] In this embodiment, the actions of various components in the card upgrading device 50 are all performed under the control of the card upgrading control unit 501. The specific card upgrading action flow is described below in conjunction with the accompanying drawings.

[0130] In this embodiment, when the user needs to shuffle the mahjong tiles 200, the user can input a shuffling instruction through the operating panel 1021, and the control device 108 controls the operating panel mechanism 102 to descend and controls the shuffling mechanism 107 to start shuffling; at this time, the user can push the scattered mahjong tiles on the table board 105 into the gap to shuffle the tiles.

[0131] After the shuffling is completed (for example, a certain shuffling time can be set), the control device 108 can control the card supply device 10 to supply cards and control the card stacking device 20 to stack cards. At the same time, the card pushing control unit 47 controls the card pushing head 431 to reach the card stacking entrance waiting position.

[0132] During the stacking process, the card supply device 108 can determine how many piles of cards have entered the card slot 312 according to the sensing signal of the stacking card counting sensor 29. Once the required number of piles (for example, the number of piles required according to the current game mode) is reached, the card supply device 108 controls the stacking device 20 to pause or stop stacking cards, and controls the card pushing device 40 to push cards. Subsequently, if the card storage sensor 35 senses the mahjong tiles 200 for the first time, it means that the card pushing device 40 has pushed the piles of cards into place, and the front pile of cards has reached the end of the card slot 312.

[0133] In this case, the control device 108 can receive the sensing signal of the load-bearing sensor 35, and when it senses that there are no mahjong tiles 200 on the carrying plate 52 (indicating that the original mahjong tiles 200 have been taken away), it directly controls the card-raising device 50 to raise the tiles, or waits for a while, and controls the card-raising device 50 to raise the tiles when the user wishes to raise the tiles according to the card-raising instruction input by the user from the operating panel 1021.

[0134] For example, in the one-time card loading mode, since the pile of cards to be raised includes both the starting hand and the cards to be taken, the control device 108 does not need to determine whether there are still mahjong tiles 200 on the carrier plate 52, but controls the card raising device 50 to raise the cards after the user inputs the card loading instruction. In the two-time card loading mode, in the case of the first card raising (raising the starting hand), the control device 108 also does not need to determine whether there are still mahjong tiles 200 on the carrier plate 52, but controls the card raising device 50 to raise the cards after the user inputs the card loading instruction. However, in the case of the second card raising (raising the cards to be taken), since the user may not have taken away all the initial hand, the control device 108 needs to directly control the card raising device 50 to raise the cards after determining that there are no mahjong tiles 200 on the carrier plate 52.

[0135] Fig.24 It is a flowchart of the card-raising action of the card-raising device according to an embodiment of the present invention.

[0136] like Fig.24 As shown, in this embodiment, under the control of the control device 108, the card upgrading device 50 performs the card upgrading process including the following steps:

[0137] Step S1, the card-raising control unit 501 receives a sensing signal from the second swing sensor 62;

[0138] Step S2, the card raising control unit 501 determines the current position of the carrier plate 52 according to the sensing signal of the second swing sensor 62, and enters step S5 when it is in the lower swing position, and enters step S3 when it is not in the lower swing position;

[0139] Step S3, the card raising control unit 501 controls the swing motor 53 to rotate, drives the swing driving wheel 56 and the swing driven wheel 57 to rotate, and then drives the swing connecting rod 55 to translate, so that the swing arm 54 drives the supporting plate 52 to swing down and the receiving end to descend, and repeats steps S2 to S3 until the card raising control unit 501 determines that the current position of the supporting plate 52 reaches the lower swing position according to the sensing signals of the first swing sensor 61 and the second swing sensor 62, and then enters step S4;

[0140] Step S4, the card raising control unit 501 controls the swing motor 53 to stop rotating, so that the carrying plate 52 is stationary at the lower swing position. At this time, the control device 108 can control the card pushing device 40 to push the card pile that needs to be put on the carrying plate 52 according to the judgment result that the position of the carrying plate 52 reaches the lower swing position. After the card pushing head 431 reaches the card raising entrance waiting position, enter step S5;

[0141] Step S5, the card raising control unit 501 controls the swing motor 53 to rotate, driving the swing driving wheel 56 and the swing driven wheel 57 to rotate, and then driving the swing connecting rod 55 to translate, so that the swing arm 54 drives the carrying plate 52 to swing and the receiving end to rise, and then enters step S6;

[0142] Step S6, the card-raising control unit 501 receives the sensing signal of the first swing sensor 61, and then enters step S7;

[0143] In step S7, the card raising control unit 501 determines the current position of the supporting plate 52 according to the sensing signal of the first swing sensor 61, and when the card raising action reaches the upper swing position, the card raising action ends.

[0144] After the card raising action is completed, the card raising control unit 501 continues to receive the sensing signal of the load-bearing sensor 502 and judges whether there are still mahjong tiles 200 on the receiving end. When the mahjong tiles 200 can still be sensed, it means that the next card raising cannot be performed. After the mahjong tiles 200 can no longer be sensed, the card raising control unit 501 judges that it is in a state where the next card raising can be performed.

[0145] Subsequently, the card advancement control unit 501 can, under the control of the control device 108, perform the next card advancement action based on the overall action of other devices (for example, whether the card pushing device 40 has pushed the front pile of cards to the end of the card slot 312), the sensing status of the load-bearing sensor 35 and / or the instructions input by the user.

[0146] Example Function and Effect

[0147] According to the card-raising device provided in this embodiment, as well as the card-loading mechanism and mahjong machine containing the card-raising device, since the swing sensing component includes a first swing sensor 61 and a second swing sensor 62, a first swing sensing part 58 that cooperates with the first swing sensor 61 and corresponds to the upper swing position of the supporting plate 52, and a second swing sensing part 59 that cooperates with the second swing sensor 62 and corresponds to the lower swing position of the supporting plate 52 are provided on the swing driven wheel 57, and the card-raising control unit 501 determines whether the supporting plate 52 has reached the upper swing position according to the sensing signal of the first swing sensor 61, and determines whether the supporting plate 52 has reached the lower swing position according to the sensing signal of the second swing sensor 62. Therefore, the card-raising control unit 501 can accurately determine the current position of the supporting plate 52, no matter what card-loading method (for example, one-time loading or two-time loading) mode is adopted, or the user suddenly inputs a card-loading instruction, the card-raising device 50 can promptly, quickly and accurately perform the card-raising action, so that the mahjong machine 100 of this embodiment can be adapted to various different application scenarios.

[0148] Moreover, since the first swing sensing part 58 and the second swing sensing part 59 are located on different circumferences of the swing driven wheel 57, during the rotation of the swing driven wheel 57, the first swing sensor 61 will not sense the second swing sensing part 59, and the second swing sensor 62 will not sense the first swing sensing part 58, that is, there will be no mutual interference between the first swing sensing part 58 and the second swing sensing part 59. Therefore, the judgment result of the card lifting control unit 501 is more accurate, and will not affect the use process due to judgment errors.

[0149] In addition, in this embodiment, since there is a load sensor 502, when there are still mahjong tiles 200 on the load plate 52, the load sensor 502 can also generate a corresponding sensing signal. Therefore, the swing control unit 501 can determine whether it is in a state where the next card raising can be performed according to the remaining mahjong tiles on the load plate 52, so that the next card raising can be performed in combination with the working conditions of other devices and the user's instructions. In this way, when the mahjong tiles 200 on the load plate 52 have not been completely grabbed, the next card raising action will not be performed, avoiding affecting the user's grabbing and using the remaining mahjong tiles 200.

[0150] Since the bearing sensor 502 is arranged at the edge of the receiving end of the bearing plate 52, even if there is only one mahjong tile 200 left, the next card raising action will not be started, thereby avoiding misjudgment when the number of mahjong tiles 200 is small and causing the next card raising action to be performed before all mahjong tiles 200 are grabbed, thereby improving the user experience.

[0151] Those skilled in the art should understand that the present invention is not limited to the above-mentioned embodiments. The above-mentioned embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the technical solution may be subject to various changes and improvements, and these changes and improvements shall fall within the scope of protection claimed by the present invention.

[0152] For example, in the embodiment, the first swing sensing part 58 and the second swing sensing part 59 are both magnets, and the first swing sensor 61 and the second swing sensor 62 are corresponding magnetic induction sensors. In the present invention, as long as the corresponding coordination between the first swing sensor 61 and the first swing sensing part 58 and the corresponding coordination between the second swing sensor 62 and the second swing sensing part 59 can be achieved, other sensors and sensing parts can also be used: for example, the first swing sensing part 58 and the second swing sensing part 59 can be set as a concave hole and / or a convex column with a specific depth or height, and the first swing sensor 61 and the second swing sensor 62 are both set as distance sensors. The card lifting control unit 501 can judge whether the sensing part reaches the bottom of the corresponding sensor according to the distance signals of the first swing sensor 61 and the second swing sensor 62, respectively, and judge the position state of the supporting plate 52 accordingly.

[0153] On the basis of the above changes, further changes can be made. Specifically, the first swing sensing part 58 can be set as one of the convex column and the concave hole, and the second swing sensing part 59 can be the other of the convex column and the concave hole, and the two can be set on the same circumference, and the overall height of the circumference is uniform except for the first swing sensing part 58 and the second swing sensing part 59; at this time, the swing sensing component can only include one distance sensor as a swing sensor, and when the swing sensor detects a signal of a longer distance, it means that the concave hole is located below it, and when it detects a signal of a shorter distance, it means that the convex column is located below it, and when it detects a signal of a distance between the two, it means that neither the concave hole nor the convex column is below it. The lifting control unit 501 can judge the position state of the carrier plate 52 based on such different signals.

[0154] In addition, in the embodiment, the first swing sensing portion 58 and the second swing sensing portion 59 are located on the same diameter, but in other embodiments, the two may not be arranged on the same diameter, as long as the positions of the two sensors are adjusted accordingly so that the first swing sensor 61 can sense the first swing sensing portion 58 and the second swing sensor 62 can sense the second swing sensing portion 59.
