Description

Technical Field

[0001] This utility model belongs to the field of mahjong machine entertainment equipment, and relates to mahjong machines, and more particularly to a tile-pushing device for pushing mahjong tiles from inside the mahjong machine to its table, as well as a tile-loading mechanism containing the tile-pushing device and a mahjong machine. Background Technology

[0002] A mahjong machine is a device that eliminates the need for users to shuffle and arrange the tiles, making it convenient for them to play the game. It typically includes a shuffling mechanism for shuffling the mahjong tiles, a tile-laying mechanism for stacking the shuffled tiles and placing them on the table for use, a control panel for users to input operation commands, and a table frame for overall support.

[0003] The card-dealing mechanism needs to be set up separately for each user. For example, a typical mahjong machine is used by four users, so four sets of card-dealing mechanisms need to be set up accordingly. Each set of card-dealing mechanisms also needs to perform functions such as stacking, storing, pushing, and raising cards. The table size should not be too large. Therefore, the layout space of the card-dealing mechanism is relatively limited, and the structural design needs to be very compact.

[0004] In some existing technologies, the card-dispensing mechanism is equipped with an annular card slot for temporarily storing card stacks and a card-pushing device for pushing the card stacks in the card slot to the card-dispensing opening. For example, CN111991798A discloses a fully automatic mahjong machine, in which the card-pushing device includes a drive motor, a card-pushing gear (card-dragging gear), a driven gear, and a telescopic arm. The drive motor drives the card-pushing gear and the driven gear to rotate, which in turn drives the telescopic arm to rotate, and the front end of the telescopic arm pushes the cards. In this structure, the telescopic arm relies on intermittent motor drive to achieve circumferential rotation. The current state of the telescopic arm and motor, the specific position of the front end of the telescopic arm pushing the tiles, and whether it will interfere with other components in the tile-adding mechanism are all difficult to determine. Therefore, the entire tile-pushing action cannot provide accurate feedback information, which is not conducive to the accurate control of the tile-pushing action and the precise coordination between the tile-pushing action and other actions such as stacking and adding tiles. It is possible that the telescopic arm will interfere with the tile-stacking device at the tile slot, resulting in fewer tiles being stacked, or that the telescopic arm will not coordinate well with the tile-lifting device, resulting in some mahjong tiles not being lifted to the table and remaining in the tile slot, thus affecting the game. Therefore, the level of intelligence of the mahjong machine needs to be improved.

[0005] In particular, if a user wishes to use different card-dealing modes, such as dealing cards all at once or dealing the starting hand and the cards to be drawn separately, the card-pushing action needs to be performed at the appropriate time according to the different modes, and needs to be more accurately coordinated with other action mechanisms to avoid mutual interference. Existing card-pushing devices lack a feedback mechanism, therefore they cannot properly set the timing of the card-pushing action, nor can they set the coordination of other action mechanisms according to the current card-pushing state; that is, they cannot effectively realize the aforementioned different card-dealing modes.

Detailed Implementation

[0044] To make the technical means, creative features, objectives and effects of this utility model easy to understand, the following describes in detail the card pushing device, card loading mechanism and mahjong machine of this utility model with reference to the embodiments and accompanying drawings.

[0045] <Example>

[0046] Figure 1 This is a structural diagram of the mahjong machine from one angle in this embodiment. Figure 2 This is a structural diagram of the mahjong machine from another angle in this embodiment.

[0047] like Figure 1 and Figure 2 As shown, this embodiment provides a mahjong machine 100 for automatically shuffling and loading mahjong tiles 200, including a shuffling mechanism, a loading mechanism 101, an operation panel mechanism 102, and a table frame mechanism 103.

[0048] The table frame mechanism 103 includes an outer frame 104, a tabletop 105 mounted on the outer frame 104, and a lower frame 106 that supports the tabletop 105 and other mechanisms. The bottom of the lower frame 106 is provided with table legs for supporting the ground.

[0049] The control panel 102 is located in the middle of the tabletop 105. It contains a control module that controls the operation of various components of the mahjong machine 100. Operation buttons are located on the top for users to input operating commands. The shuffling mechanism (not shown) is located in the middle below the tabletop 105 and is used to shuffle the used mahjong tiles 200. It includes a shuffling disc for carrying and rotating the mahjong tiles, and can specifically adopt a corresponding structure from the prior art.

[0050] The mahjong machine 100 of this embodiment can be used by four users at the same time, and is provided with four card-adding mechanisms 101, which are located at the four corners of the lower frame 106 respectively.

[0051] Figure 3 This is a structural diagram of the license plate issuing mechanism from one angle in this embodiment. Figure 4 This is a structural diagram of the license plate issuing mechanism from another angle in this embodiment.

[0052] like Figure 3 and Figure 4 As shown, the card-issuing mechanism 101 includes a card-supplying device 10, a card-stacking device 20, a card-storing device 30, a card-pushing device 40, and a card-raising device 50.

[0053] Figure 5 This is a structural diagram of the card-supplying device in this embodiment.

[0054] like Figure 3-5 As shown, the card feeding device 10 includes a card suction wheel 11, a card feeding frame 12, a belt assembly 13, and a card feeding motor 14.

[0055] The card feeder 12 is fixedly installed on the lower frame 106 and located near the shuffling mechanism 101. It 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 feeder motor 14 is connected to the card suction wheel 11 and can drive the card suction wheel 11 to rotate.

[0056] The belt assembly 13 includes a feeding belt 15 wound around the card-feeding wheel 11, a guide wheel 16 for guiding the feeding belt 15, and a tensioning wheel 17 for tensioning the feeding belt 15. The guide wheel 16 is mounted near the card-stacking device 20 so that the feeding belt 15 can transport the mahjong tiles on it to the card-stacking device 20.

[0057] In this embodiment, the card-collecting wheel 11 is equipped with several card-collecting magnets, and each mahjong tile 200 is inlaid with magnetic material that can be magnetically attracted to the shuffling magnets. When the card-collecting wheel 11 rotates under the drive of the card-feeding motor 14, the card-collecting magnets that rotate to the downward position can attract the mahjong tiles 200 below. As the card-collecting wheel 11 continues to rotate, the mahjong tiles 200 are carried to the top of the card-collecting wheel 11 and then transported to the stacking device 20 by the card-feeding belt 15.

[0058] Figure 6 This is a structural diagram of the card stacking device in this embodiment. Figure 7 This is a structural diagram of the stacking device in this embodiment. Figure 7 The stacked card housing and stacked card motor are omitted to show other internal structures.

[0059] like Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the stacking device 20 is used to stack the single mahjong tiles fed by the tile feeding device 10 to form a stack of two tiles together, and includes a stacking unit and a tile dispensing unit.

[0060] The card stacking unit includes a card stacking block 21, a card stacking block drive rod 22, a card stacking drive wheel 23, and a card stacking motor 24. The card pulling unit includes a card pulling block 25, a card pulling connecting rod 26, and a card pulling drive block 27. In addition, the card stacking device 20 also has a card stacking housing 28 that houses and supports the various components in the card stacking unit and the card pulling unit.

[0061] The top of the stacking block 21 is flat. In the initial state, this flat surface is located near the guide wheel 16 of the supply belt 15 and can receive the mahjong tiles conveyed on the supply belt 15.

[0062] The stacking block 21 is provided with a stacking block groove 211. One end of the stacking block drive rod 22 is a movable end, which is slidably fitted into the stacking block groove 211 by a slider.

[0063] like Figure 6 and Figure 7 As shown, the card stacking drive wheel 23 is mounted on the output shaft of the card stacking motor 24 and rotates under the drive of the card stacking motor 24. A card stacking drive groove 231 is provided on one side of the wheel.

[0064] The other end of the stacking block drive rod 22 is a fixed end, which has a stacking drive shaft 221 hinged to the stacking block housing 27; the middle part of the stacking block drive rod 22 is also provided with a slider that is slidably fitted in the stacking drive groove 231. When the stacking drive wheel 23 rotates, the stacking block drive rod 22 swings up and down, driving the stacking block 21 to move up and down through the movable end.

[0065] Figure 8 This is a structural diagram of one side of the stacked card block in this embodiment.

[0066] like Figure 8 As shown, the stacking drive groove 231 is approximately annular, with a concave section 231A with a decreasing radius and a convex section 231B with an increasing radius. When the slider in the middle of the stacking block drive rod 22 is in the concave section 231A, the top plane of the stacking block 21 is lower than the upper plane of the end of the feeding belt 15, and the height difference is slightly greater than the thickness of two mahjong tiles, so that the mahjong tiles fed by the feeding belt 15 can be stacked on the top plane of the stacking block 21. When the slider in the middle of the stacking block drive rod 22 moves to the convex section 231B, it can drive the stacking block 21 to move slightly upward, which facilitates the card-picking block 25 to perform the card-picking action.

[0067] The card-pulling block 25 is fixed to the top of the card-pulling linkage 26. The card-pulling linkage 26 is bent in an approximately L-shape, and its lower end is fixed to one side of the card-pulling drive block 27.

[0068] Figure 9 This is a structural diagram of the toggle drive block according to an embodiment of the present invention.

[0069] like Figure 9 As shown, the other side of the card-pulling drive block 27 is provided with an arc-shaped card-pulling groove 271, and the other side of the stacking drive wheel 23 (i.e. the opposite side of the surface where the stacking block groove 211 is located) is provided with a slider that slides into the card-pulling groove 271. As the stacking drive wheel 23 rotates, under the action of the slider and the card-pulling groove 271, the card-pulling drive block 27 moves back and forth intermittently and drives the card-pulling block 25 to move back and forth through the card-pulling connecting rod 26. Thus, when the two mahjong tiles 200 at the top of the stacking block 21 overlap to form a tile stack, the tile stack is pushed toward the tile storage device 30.

[0070] In this embodiment, the stacking device 20 also includes a counting sensor 29 facing the stacking block 21. The counting sensor 29 is a magnetic induction sensor that can generate a sensing signal when a mahjong tile with an embedded magnet passes through, thereby counting the mahjong tiles stacked and entering the tile slot 312.

[0071] Figure 10 This is a structural diagram of the card storage device in this embodiment.

[0072] like Figure 10 As shown, the card storage device 30 includes a card storage tray 31, an upper slot plate 32, a lower slot plate 33, and an inner slot plate 34.

[0073] The card storage tray 31 is approximately square in shape, with one corner notched and the other three corners rounded. Vertically upward-extending baffles 311 are provided along the edge, and the center protrudes upwards, forming a card slot 312 between the baffles 311 and the central protrusion. Additionally, a support column 313 is provided at the bottom of the card storage tray 31, which is used to mount it to the lower frame 106.

[0074] The upper groove plate 32 is a plate-shaped component that matches the shape of the baffle 311 and is embedded in the upper part of the inner surface of the baffle 311; the lower groove plate 33 is a plate-shaped component that matches the card slot 312 and is embedded in the bottom surface of the card slot 312; the inner groove plate 34 is approximately annular and matches the central protrusion of the card storage tray 31, and is installed on the outer edge of the central protrusion of the card storage tray 31.

[0075] The card feeding device 10 and the card stacking device 20 are located at the notch corner of the card storage tray 31 and are positioned near one end of the card slot 312. The card stacking block 21 is located at the end opening of the card slot 312. When the card block 25 is pushed towards the card storage device 30, the card block will enter the card slot from the end opening of the card slot 312. When the next card block is stacked and pushed towards the card slot 312 by the card block 25, the card block will also push the card blocks that have already entered the card slot 312. This process is repeated to allow a certain number of card blocks to be stored in the card slot 312.

[0076] Figure 11 This is a cross-sectional structural diagram of the card slot in this embodiment.

[0077] like Figure 11As shown, the upper slot plate 32, lower slot plate 33, and inner slot plate 34 are all adapted to the card slot 312, together forming a card storage slot structure that can store and allow card blocks to pass through. Among them, the bottom end of the upper slot plate 32 has a flange 321 protruding towards the center of the card slot 312, and the upper half of the inner slot plate 34 protrudes outward, so that the card slot 312 forms two parts with different movement radii (i.e., distances relative to the center of the card storage tray 31) (as shown by the two dashed boxes in the figure), namely the upper card slot 312A and the lower card slot 312B. The upper slot 312A and the lower slot 312B correspond to the upper and lower mahjong tiles in the tile stack, respectively. Since the upper slot 312A has a larger radius of motion, even if the upper mahjong tile moves faster due to less friction caused by the lower surface only contacting the lower mahjong tile, the upper slot 312A can still provide a slightly longer movement path, so that the upper mahjong tile will not detach from the lower mahjong tile due to the faster speed when moving in the slot.

[0078] Figure 12 This is a structural diagram of the card-pushing device at one angle in this embodiment. Figure 13 This is a structural diagram of the card-pushing device from another angle in this embodiment.

[0079] like Figure 12 and Figure 13 As shown, the card pushing device 40 includes a card pushing base 41, a card pushing rotating base 42, a card pushing arm 43, a card pushing motor 44, a card pushing drive gear 45, and a card pushing sensing unit 46.

[0080] The card holder 41 is fixedly installed in the middle of the card storage tray 31, that is, in the inner circle of the card slot 312. The middle part has a circular notch 41A, and the periphery has a rotating groove 411. The shape and outline of the rotating groove 411 are basically matched with the upper card slot 312A, but the size is smaller. At the same time, there is a recessed section 412 near the notch of the card storage tray 31.

[0081] The card pusher rotating seat 42 is rotatably mounted on the card storage tray 31 via a rotating shaft 310. The entire seat is located within a notch 41A, and its upper surface protrudes from the notch 41A. A push arm mounting protrusion 421 is provided on the upper surface of the card pusher rotating seat 42, and a push arm mounting hole 422 extending horizontally through the protrusion 421.

[0082] Figure 14 This is a structural diagram of the card-pushing arm in this embodiment.

[0083] like Figure 14 As shown, the card pusher arm 43 is a telescopic arm, which is roughly L-shaped and includes a card pusher head 431, a card pusher slider 432, a connecting arm 433, and a guide arm 434.

[0084] The connecting arm 433 is generally rectangular in shape and has a connecting groove 4331 extending along its length. The cross-section of the connecting groove 4331 in its extending direction is similar to the top of a "U" shape, that is, it includes an upper horizontal section, a downwardly extending transition section, a lower horizontal section, an upwardly extending transition section, and another upper horizontal section connected in sequence, and the connection positions between each section have rounded corners. The connecting arm 433 is movably inserted into a square push arm mounting hole 422. The push arm mounting hole 422 is located on one side of the center 42A of the push card rotating seat 42, that is, the push card arm 43 is eccentrically arranged relative to the push card rotating seat 42 (push card driven gear).

[0085] One end of the guide arm 434 is embedded and fixed in the connecting groove 4331, and the other end is fixedly mounted with a pusher head 431. The guide arm 434 is an irregularly shaped elongated strip, and its cross-sectional shape matches the cross-sectional shape of the telescopic receiving groove 4331, that is, it is also similar to the top of a "U" shape. The connection points between each segment have rounded corners, which allows the guide arm 434 to have sufficient structural strength while being relatively thin, and it can also play a certain guiding role when telescopically extending relative to the connecting arm 433. One side of the middle of the guide arm 434 has a downwardly extending L-shaped mounting plate portion 4341. A pusher slider 432 is rotatably mounted below the end of the mounting plate portion 4341. The pusher slider 432 is cylindrical, and its axis is perpendicular to the length direction of the pusher arm 43. The pusher slider 432 is slidably embedded in the rotating groove 411.

[0086] The card pusher head 431 is an irregularly shaped part, generally L-shaped, with a card pusher head mounting part 4311 and a card pusher rod part 4312 that are roughly perpendicular to each other. The card pusher head mounting part 4311 has a mounting hole shaped like the top of a "U" character, which fits into the other end of the guide arm part 433. The card pusher rod part 4312 includes an upper card pusher part 43121 and a lower card pusher part 43122. The upper card pusher part 43121 is generally rectangular plate-shaped, with one side being a first card pusher surface 43121a, which is a long strip plane perpendicular to the width direction of the card pusher arm 43. The lower pusher portion 43122 is roughly L-shaped. It extends downward from the bottom of the upper pusher portion 43121, and then extends outward from one side of the first pusher surface 43121a of the upper pusher portion 43121 along the width direction of the pusher arm 43. A lateral protrusion is formed at the bottom of the pusher arm 4312. The outer end face of the lateral protrusion is the second pusher surface 43122a, which is a rectangular plane and is also perpendicular to the width direction of the pusher arm 43. That is, in the width direction of the pusher arm 43, the second pusher surface 43122a is located further outward than the first pusher surface 43121a. In addition, the other side of the pusher arm 4312 opposite to the second pusher surface 43122a is inclined relative to the length direction of the pusher arm 4312, making the width of the bottom end of the pusher arm 4312 smaller.

[0087] In this embodiment, the guide arm 434 is made of metal, while the connecting arm 433 and the pusher head 431 are both made of plastic.

[0088] The card-pushing motor 44 is located below the card-pushing base 41, and a card-pushing main gear 45 is mounted on its output shaft. The lower surface of the card-pushing rotating base 42 is provided with rotating seat teeth 423 (i.e., card-pushing driven gears) that mesh with the card-pushing main gear 45, thereby enabling the card-pushing motor 44 to drive the card-pushing rotating base 42 to rotate. When the card-pushing rotating base 42 rotates, the card-pushing slider 432 also moves accordingly within the rotating groove 411, driving the card-pushing head 431 to push the card blocks in the card slot 321. Since the rotating groove 411 has a recessed section 412, when the card-pushing slider 432 reaches the position of the recessed section 412, the distance between the card-pushing slider 432 and the rotation center (i.e., the rotation shaft 310) of the card-pushing rotating base 42 will shorten, causing the card-pushing head 431 to retract inward toward the rotation center and not contact the components of the card-feeding device 10 and the card-stacking device 20, thereby avoiding mutual interference.

[0089] When the pusher head 431 is in the slot 312, the second pusher face 43122a is located in the lower slot 312B, and the upper part of the first pusher face 43121a is located in the upper slot 312A. Both pusher faces are basically perpendicular to the extension direction of the slot 312. Therefore, in the pushing direction, the lower layer mahjong tiles in the slot 312 are relatively forward compared to the upper layer mahjong tiles. That is, the upper layer mahjong tiles always remain slightly behind during the movement.

[0090] When the tile stack reaches the tile lifting device 50, the upper layer of mahjong tiles has less friction because it only contacts the lower layer of mahjong tiles. After the pushing force of the tile pusher 431 is removed, it usually slides forward a short distance. However, in this embodiment, through the combination of the structural design of the tile pusher protrusion 433 and the larger movement radius of the tile loading groove 312A, the upper layer of mahjong tiles always stays slightly behind during the movement. After the pushing force is removed, the upper layer of mahjong tiles slides a short distance and then overlaps exactly on top of the lower layer of mahjong tiles, so that the mahjong tiles can be stacked neatly when the tiles are loaded.

[0091] Figure 15 This is a top view of the card storage device and card pushing device in this embodiment. The card pushing rotating seat is not shown in the figure. Figure 16 yes Figure 15 Enlarged view of the area inside frame A. Figure 15 and Figure 16 The push plate rotating seat is not shown in the image, and Figure 16 The dotted line in the middle shows the push card from the edge structure of the gear.

[0092] like Figure 15 and Figure 16 As shown, the card push sensing assembly 46 includes a first card push sensor 461, a second card push sensor 462, a card push sensing part (not shown in the figure), and a card push sensing circuit board 464.

[0093] The pusher rotating seat 42 has a sensor mounting hole 425 on one side edge. The sensor mounting hole 425 extends along the axial direction of the pusher rotating seat 42, and its axial cross-section is circular, with the internal diameter being larger than the diameters at both ends. The pusher sensing part is a roughly cylindrical magnet, which is disposed in the sensor mounting hole 425, and thus can move along an arc as the pusher rotating seat 42 rotates. In addition, the sensor mounting hole 425 and the pusher arm mounting hole 422 are located on opposite sides of a diameter direction of the pusher rotating seat 42. The line connecting the sensor mounting hole 425 and the center 42A of the pusher rotating seat 42 forms an acute angle with the length direction of the pusher arm 42. The angle is 40° to 50°, and in this embodiment, it is 45°.

[0094] The card-pushing sensing circuit board 464 is roughly T-shaped, with an arc-shaped upper part. The first card-pushing sensor 461 and the second card-pushing sensor 462 are both magnetic induction sensors, respectively located at opposite ends of the upper part of the circuit board 464. These two sensors, along with the card-pushing sensing part, are all located on the same circumference of the card-pushing rotating base 42, meaning their distances from the central axis of the base are approximately equal. Therefore, both sensors are located directly below the moving path of the card-pushing sensing part. When the card-pushing sensing part moves directly above one of these two sensors, that sensor can detect the card-pushing sensing part and generate a corresponding sensing signal.

[0095] The first card pusher sensor 461 is located closer to the card inlet 312C and corresponds to the predetermined card stacking entrance waiting position P1 in front of the card inlet 312C. When the card pusher rotating seat 42 rotates to the point where the first card pusher sensor 461 senses the card pusher sensing part (that is, when the card pusher sensing part is approximately directly above the first card pusher sensor 461), and under the guidance of the recessed section 412, the card pusher head 431 is positioned at the predetermined card stacking entrance waiting position P1. In this embodiment, the card stacking entrance waiting position P1 is located behind the card inlet 312C along the card pusher direction, between the card inlet 312C and the card lifting device 50, where there is relatively large open space. The aforementioned recessed section 412 is located next to the card stacking entrance waiting position P1.

[0096] The second push card sensor 462 is relatively closer to the card outlet 312D and is set in accordance with the predetermined card raising entrance waiting position P2 in front of the card outlet 312D. When the push card rotating seat 42 rotates to the point where the second push card sensor 462 senses the push card sensing part, the push card head 431 is located at the card raising entrance waiting position P2.

[0097] like Figure 16 As shown, the line connecting the first card pusher sensor 461 and the center 42A of the card pusher rotating seat 42 is the first connecting line L1, and the line connecting the second card pusher sensor 462 and the center 42A of the card pusher rotating seat 42 is the second connecting line L2. The included angle between the first connecting line L1 and the second connecting line L2 is 40° to 50°, and in this embodiment it is 45°. Furthermore, this included angle corresponds to the included angle between the direction of the line connecting the sensor mounting hole 425 and the center 42A of the card pusher rotating seat 42 and the length direction of the card pusher arm 42.

[0098] In the initial state, the pusher head 431 is located at the waiting position P1 at the stacking entrance, thus avoiding interference with the stacking device 20. After the stacking device 20 completes the stacking and dispensing of a predetermined number of mahjong tiles to form several stacks of mahjong tiles, the pusher motor 44 drives the pusher arm 43 to rotate. The pusher arm 43 pushes these stacks of mahjong tiles along the tile slot 312 until the pusher arm 43 rotates to the point where the first pusher sensor 461 senses the pusher sensing part. Based on the sensing signal, the pusher motor 44 is controlled to stop, so that the pusher head 431 stops at the waiting position P2 at the lifting entrance. At this time, the several stacks of mahjong tiles pushed by it are located at the bottom of the support plate 52. The pusher head 431 can prevent these stacks of mahjong tiles from falling off the support plate 52 and will not interfere with the end of the support plate 52.

[0099] Then, when the support plate 52 rotates to lift the cards, the pusher motor 44 drives the pusher arm 43 to rotate again until the pusher arm 43 rotates to the point where the second pusher sensor 462 senses the pusher sensing part. Based on the sensing signal, the pusher motor 44 is controlled to stop, so that the pusher head 431 stops at the card stacking entrance waiting position P1. At this time, the pusher head 431 is located near the card inlet 312C and will not interfere with the card stacking device 20.

[0100] Figure 17 This is a structural diagram of the card-raising device in this embodiment. Figure 18 This is a structural diagram of the card-raising device in this embodiment. Figure 18 The support frame is omitted in the text.

[0101] like Figure 2 , Figure 3 , Figure 17 and Figure 18 As shown, the card lifting device 50 is used to push the card stacks delivered by the card pushing device 40 to rise to the tabletop. It includes a support unit and a swing unit. The support unit includes a support frame 51 and a support plate 52. The swing unit includes a swing motor 53, a swing arm 54, a swing linkage 55, and a swing gear set composed of a drive wheel 56 and a driven wheel 57.

[0102] The support frame 51 is fixedly installed on the lower frame 106, located near the card supply frame 12 and fixedly connected to the card supply frame 12 to form a frame. An opening is formed at the lower end of one side of the support frame 51 to facilitate the exposure of the card suction wheel 11, and a support groove 511 is formed at the upper end. The support groove 511 has an open end 511A, which faces the tail end of the card slot 312, and the depth of the support groove 511 gradually increases from the other end to the open end 511A.

[0103] The support plate 52 is used to support the card stack to be placed. The support plate 52 is a long strip plate-shaped piece. One end is a receiving end that can receive the card stack pushed by the card pusher arm 43 from the card slot 312, located at the open end 511A; the other end is a mounting end, which is rotatably mounted on the other end of the support slot 511 opposite to the open end 511A via a rotating shaft, so that the support plate 52 can swing up and down in the support slot 511, and correspondingly its receiving end can rise or fall at the open end 511A.

[0104] The tabletop 105 is provided with a card slot 105A that corresponds to the position and shape of the support plate 52. When the support plate 52 swings upward until the receiving end rises to the highest position, the entire support plate 52 protrudes from the card slot 105 onto the tabletop, and the user can remove the card stacks on the support plate 52. The position of the support plate 52 in this state is referred to as the upward swing position of the support plate 52. When the support plate 52 swings downward until the receiving end descends to the lowest position, the receiving end is basically flush with the bottom of the card slot 312. The card pushing arm 43 can push the card stacks in the card slot 312 from the receiving end onto the support plate 52. The position of the support plate 52 in this state is referred to as the downward swing position of the support plate 52.

[0105] The swing motor 53 is installed below the card storage tray 31, and its output axis extends upward to the card storage tray 31.

[0106] The drive wheel 56 is mounted on the output shaft of the swing motor 53 and can rotate under the drive of the swing motor 53.

[0107] A driven wheel groove 314 is provided on the card storage plate 31 near the drive wheel 56. The driven wheel 57 is rotatably mounted in the driven wheel groove 314 through a driven wheel shaft 316 and meshes with the drive wheel 56. Therefore, it can be driven by the drive wheel 56 to rotate under the drive of the swing motor 53.

[0108] Figure 19 This is a structural diagram of the driven wheel side surface in this embodiment.

[0109] like Figure 19 As shown, a track groove 572 is provided on one side surface of the driven wheel 57. The track groove 572 is shaped to protrude on one side. The farthest part of the track groove 572 from the center of the driven wheel 57 (rotation center, i.e., the center of the driven wheel shaft 316) is the far end 572A, and the closest part to the center of the driven wheel 57 is the near end 572B.

[0110] Figure 20 This is a structural diagram of the swing linkage in this embodiment.

[0111] like Figure 20As shown, each end of the swing link 55 has a straight rod-shaped end. One end is a driven wheel engagement end 551 that engages with the driven wheel 57, and the other end is a swing engagement end 552 that engages with the swing arm 54. In this embodiment, the driven wheel engagement end 551 and the swing engagement end 552 are parallel in length. The middle part of the swing link 55 has a first transition section 555 and a second transition section 556 that connect the driven wheel engagement end 551 and the swing engagement end 552. One end of the first transition section 555 is connected to the driven wheel engagement end 551 and is inclined relative to it, with an obtuse angle between them. The two ends of the second transition section 556 are connected to the other end of the first transition section 555 and the swing engagement end 552, respectively, and are approximately perpendicular to the first transition section 555 and inclined relative to the swing engagement end 552, with an obtuse angle between them. A clearance groove 5551 is provided at one end of the first transition section 555 near the second transition section 556. The clearance groove 5551 extends through the width of the first transition section 555. The groove width is slightly larger than the width of the bottom end of the push rod 4212 of the push arm 42. Therefore, when the push arm 42 rotates, the clearance groove 5551 can make way for it.

[0112] The driven wheel groove 314 has a straight connecting rod mating groove 315 whose size matches the driven wheel mating end 551. The driven wheel mating end 551 is located in the connecting rod mating groove 315, so that the driven wheel mating end 551 is approximately below the driven wheel 57.

[0113] The side surface of the driven wheel 57 with the track groove 572 facing down, and the upper surface of the driven wheel mating end 551 is also provided with a roller 553. The roller 553 is slidably embedded in the track groove 572, so that when the driven wheel 57 rotates, it can drive the swing link 55 to reciprocate along the length direction of the link mating groove 315 through the roller 553.

[0114] The lower end of the swing arm 54 is provided with a swing shaft 541, which is provided through the support frame 51, so that the swing arm 54 can rotate around the swing shaft 541 and swing up and down.

[0115] The swing shaft 541 has circumferentially distributed swing shaft teeth 542 on the end exposed outside the support frame 51, and swing mating teeth 554 are distributed along the length direction on the swing mating end 552. The swing shaft teeth 542 and the swing mating teeth 554 mesh with each other. When the swing connecting rod 55 moves back and forth, it can drive the swing arm 54 to swing up and down.

[0116] The lower surface of the receiving end of the bearing plate 52 is provided with a bearing mating groove 521, and the upper end of the swing arm 54 is provided with a swing slider 543 that is slidably engaged in the bearing mating groove 521. When the swing arm 54 swings up and down under the drive of the swing connecting rod 55, it can drive the receiving end of the bearing plate 52 to swing up and down, that is, swing back and forth between the upper swing position and the lower swing position.

[0117] Since the far end 572A and the near end 572B of the track groove 572 correspond to the two ends of the reciprocating translation stroke of the swing link 55, when the roller 553 moves to the far end 572A, the swing arm 54 will rotate away from the swing link 55, and vice versa.

[0118] In this invention, depending on the different meshing states of the swing shaft tooth 542 and the swing mating tooth 554, the relative positions of the swing connecting rod 55 and the swing arm 54 can change. Therefore, the movement of the swing connecting rod 55 can correspond to different lifting and lowering movements of the swing arm 54, as follows:

[0119] When the swing link 55 is in the retracted state (i.e., the roller 553 is located at the proximal end 572B and the swing link 55 is located closer to the driven wheel 57), the swing arm 54 is facing upwards, and the rotational motion of the swing arm 54 away from the swing link 55 will cause its upper end to move downwards; when the swing link 55 is in the retracted state and the swing arm 54 is facing the swing link 55 (at this time the swing arm 54 is in an approximately horizontal state), the rotational motion of the swing arm 54 away from the swing link 55 will cause its upper end to move upwards.

[0120] Therefore, the far end 572A of the track groove 572 corresponds to one of the upper swing position and the lower swing position of the support plate 52, while the near end 572B corresponds to the other of the upper swing position and the lower swing position.

[0121] In this embodiment, the first scenario (i.e., the swing link 55 is in the retracted state and the swing arm 54 is in the vertical state) will be used as an example for specific explanation.

[0122] Figure 21 This is a structural diagram of the other side surface of the driven wheel in this embodiment.

[0123] like Figure 21 As shown, the other surface (i.e., the upward-facing surface) of the driven wheel 57 is provided with a first lifting plate sensor 58 and a second lifting plate sensor 59, both of which are magnets. With the center of the driven wheel shaft 316 as the center, the first lifting plate sensor 58 and the second lifting plate sensor 59 are distributed on both sides of the driven wheel shaft 316, and are located on the same diameter of the driven wheel 57, but on different circumferences of the driven wheel 57. Furthermore, in this embodiment, the distal end 572A and the proximal end 572B are also on the same diameter line of the driven wheel 57.

[0124] The swing unit also includes a sensing component mounted above the driven wheel 57. The sensing component includes a first lifting sensor 61 that cooperates with the first lifting sensor 58 and a second lifting sensor 62 that cooperates with the second sensing component 58. Both of them are magnetic induction sensors.

[0125] In this embodiment, the first card-lifting sensor 61 and the second card-lifting sensor 62 are both located at specific positions, such that when the roller 553 reaches the near end 572B, the first card-lifting sensor 58 is exactly below the first card-lifting sensor 61, and at the same time, when the roller 553 reaches the far end 572A, the second card-lifting sensor 59 is exactly below the second card-lifting sensor 62.

[0126] Thus, when the roller 553 reaches the proximal end 572B, causing the swing arm 54 to be in a vertical state and the support plate 52 to be in an upward swing position, the first plate-lifting sensor 61 just senses the first plate-lifting sensing part 58 and outputs a sensing signal; when the roller 553 reaches the distal end 572A, causing the swing arm 54 to swing from a vertical state to a horizontal state and the support plate 52 to be in a downward swing position, the second plate-lifting sensor 62 just senses the second plate-lifting sensing part 59 and outputs a sensing signal.

[0127] Furthermore, when roller 553 is neither at the near end 572B nor at the far end 572A, neither the first plate lifting sensor 61 nor the second plate lifting sensor 62 outputs a sensing signal, indicating that the carrier plate 52 is at a position between the upper swing position and the lower swing position.

[0128] Therefore, in this embodiment, the first card-lifting sensor 58 corresponds to the upward swing position of the support plate 52, and the second card-lifting sensor 59 corresponds to the downward swing position of the support plate 52. By observing the real-time output signals from the first card-lifting sensor 61 and the second card-lifting sensor 62, it is possible to accurately determine whether the support plate 52 is currently in the downward swing position, the upward swing position, or a position between the two.

[0129] The role and effect of the embodiments

[0130] According to the card pushing device, card feeding mechanism, and mahjong machine provided in this embodiment, since the card pushing device includes a card pushing rotating seat, a card pushing arm, and a card pushing sensing component, the card pushing sensing component includes a card pushing sensing part disposed on the card pushing rotating seat and a first card pushing sensor and a second card pushing sensor disposed correspondingly below the card pushing rotating seat. These two sensors are respectively set to a predetermined card stacking entrance waiting position before the card slot inlet and a predetermined card lifting entrance sensing position before the card outlet. Therefore, by sensing the card pushing sensing part through these two sensors, the current position of the card pushing head of the card pushing arm can be accurately determined, which facilitates the control of the working actions of each component based on the position state in the automatic control.

[0131] Furthermore, since the card-pushing sensing part is a magnet, and the first and second card-pushing sensors are corresponding magnetic induction sensors, the card-pushing sensing part is set in the through hole on the edge of the card-pushing rotating seat. Therefore, only when the card-pushing sensing part is rotated to approximately the square of the first and second card-pushing sensors can one of these two sensors sense the card-pushing sensing part through the lower opening of the through hole, thereby accurately positioning the position of the card-pushing arm. Therefore, by controlling the card-pushing motor based on the sensing signals of these two card-pushing sensors, the card-pushing head at the end of the card-pushing arm can be accurately stopped at the corresponding predetermined position.

[0132] Furthermore, since there is an angle of 40° to 50° between the line connecting the two predetermined positions and the center of the card pusher rotating seat, and the two card pusher sensors are respectively set on the two connecting lines and corresponding to the edge of the card pusher rotating seat, sufficient spacing can be provided between the two card pusher sensors in a limited space. The two card pusher sensors will not interfere with each other or cause false triggering, which can make the positioning control of the card pusher head more accurate.

[0133] Furthermore, since the predetermined card stacking entrance waiting position is in front of the card slot inlet, the card pusher head can be paused at this position based on the sensing signal of the first card pusher sensor, without interfering with the operation of the card stacking device, and can quickly start the card pushing action after card stacking and card pushing are completed; in addition, the card pusher arm rotates and extends under the guidance of a rotating groove, which has a recessed part next to the card stacking entrance waiting position, so that the card pusher head can also be retracted at this position, further avoiding interference with other components on both sides.

[0134] Furthermore, since the predetermined waiting position for raising tiles is in front of the tile outlet of the tile slot, the tile pusher head can be paused at this position, i.e., paused on the outside of one end of the support plate, based on the sensing signal of the second tile pusher. This not only prevents it from interfering with the rotation and tile raising action of the support plate, but also limits the number of tiles pushed onto the support plate, preventing them from sliding off the support plate and affecting the number of mahjong tiles raised to the table.

[0135] Furthermore, one side of the pusher head has two non-coplanar pusher surfaces, a first pusher surface and a second pusher surface, and the tile slot has a lower tile slot and an upper tile slot with a relatively larger radius of motion. Therefore, through the cooperation of the first pusher surface with the upper tile slot and the second pusher surface with the lower tile slot, the lower layer of mahjong tiles in the tile slot can always be pushed onto the table while maintaining a slightly lagging motion behind the upper layer of mahjong tiles. Since the friction between the lower layer of mahjong tiles and the table is significantly greater than the friction between the two layers of mahjong tiles, this design allows the upper layer of mahjong tiles to slide a relatively longer distance after the two layers of mahjong tiles are on the table, thus aligning the two layers of mahjong tiles on the table. This provides a better viewing experience for the user, eliminates the need for manual aligning of the tiles, and is more convenient.

[0136] The above embodiments are only used to illustrate the specific implementation of the present utility model, and the present utility model is not limited to the scope of the above embodiments. Those skilled in the art should understand that the present utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are only for illustrating the principles of the present utility model. Various changes and modifications can be made to the present utility model without departing from the spirit and scope of the present utility model, and all such changes and modifications fall within the scope of the present utility model as claimed.

[0137] For example, in the above embodiment, both the first card-lifting sensing part 58 and the second card-lifting sensing part 59 are magnets, and the first card-lifting sensor 61 and the second card-lifting sensor 62 are corresponding magnetic induction sensors. In this utility model, as long as the corresponding cooperation between the first card-lifting sensor 61 and the first card-lifting sensing part 58 and the corresponding cooperation between the second card-lifting sensor 62 and the second card-lifting sensing part 59 can be achieved, other sensors and sensing parts can also be used. For example, the first card-lifting sensing part 58 and the second card-lifting sensing part 59 can be set as concave holes and / or protruding pillars with a specific depth or height, and the first card-lifting sensor 61 and the second card-lifting sensor 62 can both be set as distance sensors, and the sensing part can be determined to have reached the bottom based on the sensed distance signal.

[0138] Similarly, in the above embodiment, the card-pushing sensing part is a magnet, and the first card-pushing sensor 461 and the second card-pushing sensor 462 are corresponding magnetic induction sensors. In an alternative, other sensors and sensing parts can also be used. For example, a card-pushing sensor can be set on one side edge of the card-pushing rotating seat 42 (for example, set at the position of the sensing part mounting hole 425 shown in the figure above). The card-pushing sensor is set as a distance sensor. The first card-pushing sensing part and the second card-pushing sensing part are correspondingly set below the card-pushing rotating seat 42 (for example, set at the positions of the first card-pushing sensor 461 and the second card-pushing sensor 462 shown in the figure above, respectively). For example, the first card-pushing sensing part and the second card-pushing sensing part can be set as concave holes and / or protruding pillars with a specific depth or height. The positions of the first card-pushing sensing part and the second card-pushing sensing part are respectively set to correspond to the card stacking entrance waiting position P1 and the card lifting entrance waiting position P2. The card-pushing sensor (distance sensor) can determine whether it has reached the card-pushing sensing part and which card-pushing sensing part it has reached based on the sensed distance. When the card pusher 42 rotates until the card pusher sensor on it senses the first card pusher sensor, the card pusher head 431 is positioned at the card stacking entrance waiting position P1; when the card pusher 42 rotates until the card pusher sensor on it senses the second card pusher sensor, the card pusher head 431 is positioned at the card lifting entrance waiting position P2, and the card pusher motor 44 is controlled according to the corresponding sensing signal. This achieves a similar technical effect.
