Description

Technical Field

[0001] The invention belongs to the field of mahjong game equipment, relates to a mahjong machine, and in particular to a card stacking device for stacking and transporting mahjong cards, a card loading mechanism containing the card stacking device, and a mahjong machine containing the card loading mechanism. Background Art

[0002] A mahjong machine is a device that can avoid the user's operations such as shuffling and sorting cards, making it convenient for multiple users to play the game at the same time. It usually has a shuffling mechanism for shuffling mahjong tiles, a loading mechanism for stacking the shuffled mahjong tiles and placing them on the table for use, an operating disk mechanism for users to input operating instructions, and a table frame 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, and four sets of corresponding card loading mechanisms need to be set up; each set of card loading mechanism also needs to realize functions such as stacking cards, storing cards, pushing cards, and upgrading cards.

[0004] Among them, the card stacking device is an important structure for realizing card stacking, such as the Chinese patent with patent number 202121989822.9 discloses a head assembly of a mahjong machine, including a head shell, a card pushing assembly and a cam assembly are provided on the head shell, and a card receiving seat is also provided on the head shell. The card pushing assembly includes a push head push rod and a first rolling bearing, the push head push rod is provided with a first rolling bearing, and the cam assembly is provided with a curved ring groove, the first rolling bearing is embedded in the curved ring groove and slidably cooperates with it, and when the cam assembly rotates, the cam assembly drives the push head push rod to rotate in a vertical direction.

[0005] In the above-mentioned machine head assembly, the push head push rod is vertically arranged. When the cam assembly rotates, the push head push rod and the push head swing in the vertical direction. The push head has a pushing surface for pushing the mahjong tiles on the card holder into the card storage slot. The pushing surface is tilted upward in the initial position. As the push head swings in the pushing direction, the pushing surface will slowly change position with the swing and push the side wall of the mahjong tiles to move, thereby pushing the tiles.

[0006] In actual use, it is found that the above machine head assembly makes a lot of noise and moves slowly because of the fast card pushing. In addition, because the push card surface is tilted upward in the initial position, the mahjong tiles will flip sideways when they slide into the card holder along the push card surface during the card feeding process, resulting in a failure to stack the tiles; or the next mahjong tile will be tilted and stuck between the previous mahjong tile and the push head. At this time, the push head action will prevent the next mahjong tile from being stacked on the previous mahjong tile normally, resulting in the card storage slot being unable to feed the tiles normally, thus affecting the normal operation of the mahjong machine.

[0054] Figure 5 is a structural diagram of a card stacking device in an embodiment of the present invention; Figure 6 is a structural diagram of a card dialing unit in an embodiment of the present invention; Figure 7 It is an exploded view of the card stacking device in the embodiment of the present invention.

[0055] like Figure 5 , 6 As shown in , 7, the stacking device 20 is arranged at the card supply port of the card supply device 10, and has a stacking unit and a card shifting unit. The stacking unit is used to stack the mahjong tiles supplied by the card supply device 10 to form a pile of tiles, and the card shifting unit is used to shift the pile of tiles or a piece of mahjong tiles into the card inlet 311A ​​of the card storage slot 311.

[0056] The stacking unit includes a stacking block 21 for stacking mahjong tiles, and the stacking block 21 is lifted and arranged at the card supply port. The card shifting unit includes a frame, a card shifting motor 24 installed on the frame, a card shifting driving wheel 23, a card shifting push rod 26, an auxiliary push rod 27 and a card shifting block 25.

[0057] The frame of this embodiment is a card storage tray 31, and the entire card stacking device 20 is fixed at the card inlet 311A ​​of the card storage tray 31. Among them, the card shifting motor 24 is fixed at the bottom of the card storage tray 31. The card shifting driving wheel 23 is installed on the main shaft of the card shifting motor 24 through a shaft sleeve, and the two are coaxial and horizontally arranged, and are driven to rotate by the card shifting motor 24.

[0058] A curved annular groove 232 is provided on the outer circumferential wall of the card-digging driving wheel 23. A card-digging push rod 26 and an auxiliary push rod 27 are arranged horizontally in sequence above the card-digging driving wheel 23 and distributed along the axial direction of the card-digging driving wheel 23, and a movable gap is formed between the card-digging push rod 26 and the auxiliary push rod 27.

[0059] One end of the card push rod 26 is hinged to the frame (card storage tray 31) in front of the card supply port through the first rotating shaft 262, and the middle part is bent and provided with a card sliding member 263 that is slidably fitted in the curved ring groove 232, and the card sliding member 263 is a slider or a roller; the other end of the card push rod 26 is connected to the card block 25. The structure of the auxiliary push rod 27 is basically the same as that of the card push rod 26, only the card sliding member 263 is missing. Specifically, one end of the auxiliary push rod 27 is hinged to the frame (card storage tray 31) in front of the card supply port through the second rotating shaft 272, and the other end is arranged on the card block 25.

[0060] Specifically, a connecting column 1 261 is vertically arranged at the other end of the card-digging push rod 26, and a mounting hole 1 251 matching the connecting column 1 261 is provided on the card-digging block 25, and the connecting column 1 261 rotates in the mounting hole 1 251; a connecting column 271 is vertically arranged at the other end of the auxiliary push rod 27, and a mounting hole 252 matching the connecting column 271 is provided on the card-digging block 25, and the connecting column 271 rotates in the mounting hole 252. The axes of the connecting column 1 261, the first rotating shaft 262, the connecting column 271, and the second rotating shaft 272 are all vertically arranged and separately installed with the corresponding card-digging push rod 26 or the auxiliary push rod 27.

[0061] In another embodiment, the connecting column 1 261 and the connecting column 271 are both hollow and have open upper ends and elastic snaps, so that the connecting column 1 3b and the connecting column 2 7b can be more smoothly snapped into the corresponding mounting hole 1 251 and the mounting hole 2 252.

[0062] In another embodiment, the card-dipping push rod 26, the connecting column 1 261, and the first rotating shaft 262 are an integral structure, and preferably the three are integrally molded by injection molding; the auxiliary push rod 27, the connecting column 271, and the second rotating shaft 272 are an integral structure, and preferably the three are integrally molded by injection molding.

[0063] In addition, if Figure 3 As shown, in order to prevent impurities from entering the card dialing drive wheel 23, a cover plate 28 is also provided above the card dialing drive wheel 23, and the cover plate 28 is fixed on the frame (card storage tray 31). The cover plate 28 can also facilitate the installation, debugging and maintenance of the card dialing drive wheel 23, the card dialing push rod 26 and the auxiliary push rod 27.

[0064] The card-digging block 25 has a vertical card-digging surface 253, and a side of the card-digging surface 253 close to the card supply port is provided with an inclined surface for facilitating the entry of mahjong tiles into the stacking block 21. When the card-digging motor 24 rotates, the card-digging push rod 26 can swing horizontally along with the rotation of the card-digging driving wheel 23, so that the card-digging surface 253 of the card-digging block 25 swings back and forth in a vertical posture, and the mahjong tiles on the stacking block 21 are dialed into the card inlet 311A ​​of the card storage slot 311.

[0065] During the swinging process, the card-digging surface 253 of the card-digging block 25 will not tilt upward or downward, which can prevent the mahjong tiles from tipping over or failing to stack due to the upward tilt of the card-digging surface 253 during the supply of tiles.

[0066] In another embodiment, the card-moving block 25 can be directly fixed to the movable end of the card-moving push rod 26, eliminating the auxiliary push rod 27, which can also prevent the mahjong tiles from tipping over or failing to stack.

[0067] In this embodiment, the auxiliary push rod 27 can, on the one hand, increase the stability of the card-digging push rod 26 driving the card-digging block 25 to swing; on the other hand, it can also control the left and right offset angle of the card-digging surface 253 when swinging, so that the vertical card-digging surface 253 can send the mahjong cards into the card storage device as much as possible along the arc direction of the card storage slot.

[0068] In addition, sound insulation layers are provided on the card-pulling surface 253, the top surface of the card stacking block 21, and the side wall of the frame (card storage tray 31) facing the card supply opening to reduce the sound of the collision of mahjong tiles.

[0070] like Figure 8 As shown, the curved annular groove 232 has a starting groove portion 232A, a shifting groove portion 232B and a reset groove portion 232C.

[0071] When the card-digging sliding member 263 of the card-digging push rod 26 moves to the starting groove portion 232A, the movable end of the card-digging push rod 26 and the card-digging block 25 are both maintained at the initial position on the side of the card-stack block 21 away from the card inlet 311A; when the card-digging sliding member 263 of the card-digging push rod 26 moves to the card inlet 311A ​​of the card storage slot (i.e., the card-digging direction), and the mahjong cards of the card-stack block 21 are dialed into the card inlet 311A; when the card-digging sliding member 263 of the card-digging push rod 26 moves to the reset groove portion 232C, the movable end of the card-digging push rod 26 and the card-digging block 25 are reset to the initial position.

[0072] Fig. 9 1 is an exploded view of the card dialing driving wheel in an embodiment of the present invention.

[0073] like Fig. 9 As shown, the card dialing driving wheel includes a first driving wheel 233, a second driving wheel 234 and a fixing member.

[0074] A first groove wall 2331 is formed on the periphery of the end face of the first driving wheel 233; a second groove wall 2341 matching the first groove wall 2331 is formed on the periphery of the end face of the second driving wheel 234; the fixing member is preferably a screw, which is used to fix the first driving wheel 233 and the second driving wheel 234, and form a curved annular groove 232 between the first groove wall 2331 and the second groove wall 2341, so as to facilitate the processing and molding of the card dialing driving wheel and reduce the production cost. The material can be plastic or metal.

[0075] To facilitate positioning and fixing, at least one positioning column and at least one positioning groove matching the positioning column are respectively arranged on the corresponding end faces of the first driving wheel 233 and the second driving wheel 234. The positioning column includes an axial positioning column and a circumferential positioning column, and the positioning groove includes a corresponding axial positioning groove and a circumferential positioning groove.

[0076] In this embodiment, an axial positioning column 2332 is arranged at the center of the end face of the first driving wheel 233, and two circumferential positioning columns 2333 are arranged on the circumferential side of the axial positioning column 2332; an axial positioning groove 2342 adapted to the axial positioning column 2332 and a circumferential positioning groove 2343 corresponding to the circumferential positioning column 2333 are opened at the center of the corresponding end face of the second driving wheel 234, a threaded hole is arranged in the circumferential positioning groove 2343, a through hole is arranged in the circumferential positioning column 2333, a fixing part passes through the through hole and is fixed in the threaded hole, thereby realizing the fixed installation of the first driving wheel 233 and the second driving wheel 234.

[0077] Fig.10 It is a structural diagram of the axial end surface of the second driving wheel in an embodiment of the present invention.

[0078] like Fig.10 As shown, on the axial projection surface of the card-dipping driving wheel, that is, through the side view of the second driving wheel 234, it can be seen that the arc angle α corresponding to the card-dipping groove portion 232B is greater than the arc angle β corresponding to the reset groove portion, and the arc angle α is 1.5-3 times of the arc angle β, preferably 2 times, such as the arc angle α=160 degrees and the arc angle β equals 80 degrees. In this way, the card-dipping block 25 can have a much longer card-dipping time than the reset time, achieving the effect of slow card-dipping and fast reset, thereby reducing the noise of card-dipping, saving the reset time when no card-dipping is performed, and improving the efficiency of the entire card-dipping action.

[0079] Fig.11 It is another angle structural diagram of the card stacking device in the embodiment of the present invention.

[0080] like Fig.11As shown, the card stacking unit and the card shifting unit of this embodiment share the card shifting motor 24 and the card shifting driving wheel 23. Among them, the end surface of the card shifting driving wheel (i.e., the outer end surface of the second driving wheel 234) is provided with a card stacking track groove 231. The card stacking unit also includes a card stacking driving rod 22, a card stacking guide seat 212 and a card stacking rotating seat 222.

[0081] A stacking card rotating shaft 221 is arranged at one end of the stacking card driving rod 22, a stacking card rotating seat 222 matching the stacking card rotating shaft 221 is arranged on the frame (card storage tray 31), and the stacking card driving rod 22 is rotatably arranged on the stacking card rotating seat 222; a slider 223 slidably engaged in the stacking card track groove 231 is also arranged in the middle of the stacking card driving rod 22; a sliding column 224 is arranged at the other end of the stacking card driving rod 22, and a stacking card block groove 211 matching the sliding column 224 and having one end open is opened on the back of the stacking card block 21, and the stacking card block groove 211 is arranged horizontally. When the card dialing driving wheel 23 rotates, the stacking card driving rod 22 swings up and down, thereby driving the stacking card block 21 to move up and down.

[0082] In order to increase the stability of the stacking block 21 moving up and down, a stacking guide seat 212 is fixedly installed at the corresponding position of the frame (card storage tray 31), and a guide groove or guide rod 213 for guiding the stacking block 21 up and down is vertically arranged in the stacking guide seat 212. The stacking block 2 has a guide part, which is movably arranged on the guide groove or guide rod 213 to achieve lifting.

[0083] Fig.12 It is a structural diagram of the card stacking track groove on the card shifting driving wheel in an embodiment of the present invention.

[0084] like Fig.12 As shown, the stacking track groove 231 is approximately annular in shape as a whole, and has an inner concave section 231A and an outer convex section 231B. When the slider in the middle of the stacking driving rod 22 moves to the outer convex section 231B, the stacking block 21 is at the highest position, and its top plane is slightly lower than the upper plane of the end of the belt assembly, and its height difference is slightly less than the thickness of a mahjong tile, so that the first mahjong tile conveyed by the belt assembly can smoothly slide into the top plane of the stacking block 21; when the slider 223 in the middle of the stacking driving rod 22 is in the inner concave section 231A, the stacking block 21 is at the lowest position, and its top plane is lower than the upper plane of the end of the belt assembly, and its height difference is slightly greater than the thickness of a mahjong tile, so that the second mahjong tile conveyed by the card supply belt 15 can be superimposed on the top plane of the stacking block 21 and located on the first mahjong tile, thereby forming a pile of tiles.

[0085] like Figure 3As shown, a counting sensor 29 is provided on the frame (card storage tray 31) on one side of the stacking block 21. The counting sensor 29 is a magnetic induction sensor that can generate an induction signal when mahjong tiles with embedded magnets pass through, thereby counting the mahjong tiles entering the stacking block 21 and the card storage slot.

[0086] like Figure 7 As shown, the other end face of the card dialing driving wheel 23 (i.e., the outer end face of the first driving wheel 233) is provided with a card dialing sensing point 291, a stacked card high position sensing point 293 and a stacked card low position sensing point 294, all of which are magnets, and the stacked card high position sensing point 293 and the stacked card low position sensing point 294 are distributed on the same radius, and the card dialing sensing point 291 is distributed on a radius further outside. The corresponding positions of the frame (card storage tray 31) are provided with a card dialing sensor 292 corresponding to the card dialing sensing point 291, and a stacked card sensor 295 corresponding to the stacked card high position sensing point 293 and the stacked card low position sensing point 294, respectively, for generating a working signal for controlling the card dialing motor to stop.

[0087] Fig.13 It is a schematic diagram of the trajectories of the card stacking block and the card shifting block in the embodiment of the present invention.

[0088] like Fig.13 As shown, the horizontal axis represents the rotation angle of the card shifting motor 24 or the card shifting driving wheel 23, the vertical axis represents the moving distance of the card stacking block and the card shifting block, the solid line represents the trajectory of the card shifting block, and the dotted line represents the trajectory of the card stacking block 21. This embodiment is illustrated by taking the card shifting driving wheel 23 rotating 360° as an example, wherein Fig.13 A / B / C / D in the figure are the corresponding angular positions.

[0089] When the card-pulling driving wheel 23 is at 0°, the card stacking block 21 is at the highest position, and the card-pulling block 25 is at the starting position. At this time, the card stacking high position sensing point 293 is opposite to the card stacking sensor 295, and the card stacking sensor 295 controls the card-pulling motor 24 to stop (i.e., in a stopped state). Figure 5 Location.

[0090] When the first mahjong tile enters the stacking block 21, the counting sensor 29 counts and controls the card shifting motor 24 and the card shifting driving wheel 23 to rotate until the stacking low position sensing point 294 rotates to the opposite side of the stacking sensor 295, and the stacking sensor 295 controls the card shifting motor 24 to stop (i.e., rotate to the angle A position). At this time, the stacking block 21 is at the lowest position and the card shifting block 25 is still at the starting position.

[0091] When the second mahjong tile enters the stacking block 21, the counting sensor 29 counts and controls the card-moving motor 24 and the card-moving driving wheel 23 to rotate, first driving the stacking block 21 to move to the highest position and rotate to the angle B position; then driving the card-moving block 25 to move in the card-moving direction, and the card pile formed by the above two mahjong tiles is moved into the card storage slot (i.e. rotated to the angle D position), and finally reset until the stacking high-position sensing point 293 moves to the opposite side of the stacking sensor 295, and the stacking sensor 295 controls the card-moving motor 24 to stop, thereby completing the stacking and moving of a group of card piles, and the next group of card piles is circulated in sequence.

[0092] When the counting sensor 29 recognizes that the number of mahjong tiles in the card storage slot has reached the specified number, the card dialing block 25 will reset to the starting position and continue to move until the card dialing sensing point 291 moves to the opposite side of the card dialing sensor 292, and the card dialing sensor 292 controls the card dialing motor 24 to stop. At this time, the card dialing motor 24 rotates to the angle C position, and the card dialing block 25 moves to the center position of the card stacking block 21 and can block the card supply port to prevent the mahjong tiles in the card supply device 10 from continuing to come out.

[0093] Functions and Effects of the Embodiments

[0094] According to the card pushing device, card loading mechanism and mahjong machine provided in this embodiment, since on the axial projection surface of the card-digging driving wheel, the arc angle α corresponding to the card-digging groove portion 232B is greater than the arc angle β corresponding to the reset groove portion, and the arc angle α is 1.5-3 times the arc angle β, the card-digging block 25 can be made to have a much longer card-digging time than the reset time, thereby achieving the effect of slow card-digging and fast reset, thereby reducing the noise of card-digging, saving the reset time when no card-digging is performed, and improving the efficiency of the entire card-digging action.

[0095] On this basis, in this embodiment, the card-playing driving wheel includes a first driving wheel 233, a second driving wheel 234, and a fixing member. A first groove wall 2331 is formed on the periphery of the end surface of the first driving wheel 233; a second groove wall 2341 matching the first groove wall 2331 is formed on the periphery of the end surface of the second driving wheel 234; the fixing member fixes the first driving wheel 233 and the second driving wheel 234, and forms a curved annular groove 232 between the first groove wall 2331 and the second groove wall 2341, so as to facilitate the processing and molding of the card-playing driving wheel and reduce the production cost.

[0096] In this embodiment, the card-digging block 25 has a vertical card-digging surface 253. When the card-digging motor 24 rotates, the card-digging push rod 26 can swing horizontally with the rotation of the card-digging driving wheel 23, so that the card-digging surface 253 of the card-digging block 25 swings back and forth in a vertical posture, and the mahjong tiles on the stacking block 21 are dialed into the card inlet 311A ​​of the card storage slot 311. In this way, during the swinging process, the card-digging surface 253 of the card-digging block 25 will not tilt upward or downward, which can prevent the mahjong tiles from tipping over or failing to stack due to the upward tilt of the card-digging surface 253 during the card supply, making the stacking smoother.

[0097] At the same time, a card-digging push rod 26 and an auxiliary push rod 27 are arranged horizontally above the card-digging driving wheel 23 and are distributed along the axial direction of the card-digging driving wheel 23. The auxiliary push rod 27 of this embodiment can increase the stability of the card-digging push rod 26 driving the card-digging block 25 to swing, and can also control the left and right deviation angle of the card-digging surface 253 when swinging, so that the vertical card-digging surface 253 can send the mahjong cards into the card storage device as much as possible along the arc direction of the card storage slot.

[0098] Furthermore, a stacking guide seat 212 is fixedly installed on the frame (card storage tray 31), and a guide groove or guide rod 213 for guiding the stacking block 21 up and down is vertically arranged in the stacking guide seat 212. The stacking block 2 has a guide part, and the guide part is movably arranged on the guide groove or guide rod 213 to achieve lifting, thereby increasing the stability of the stacking block 21 moving up and down.

[0099] In addition, when the counting sensor 29 recognizes that the number of mahjong tiles in the card storage slot has reached the specified number, the card dialing block 25 will continue to move after resetting to the starting position until the card dialing sensing point 291 moves to the opposite side of the card dialing sensor 292, and the card dialing sensor 292 controls the card dialing motor 24 to stop. At this time, the card dialing motor 24 rotates to the angle C position, and the card dialing block 25 moves to the center position of the stacking block 21, and can block the card supply port to prevent the mahjong tiles in the card supply device 10 from continuing to come out.
