Description

Technical Field

[0001] The present invention relates to the technical field of automatic mahjong machines, and particularly relates to a stacked card and lifted card integrated structure and a mahjong machine. Background Art

[0002] In the prior art, a fully automatic mahjong machine generally has a shuffling structure, a card feeding structure, a stacking structure, a pushing structure and a lifting structure. Its working principle is that the shuffling structure shuffles the mahjong tiles in the shuffling chassis, the card feeding structure transports the mahjong tiles in the shuffling chassis to the stacking structure, the stacking structure arranges the mahjong tiles transported by the card feeding structure regularly (usually two or three mahjong tiles stacked together) and transports them to the card feeding track, and the pushing structure pushes the arranged mahjong tiles on the card feeding track from the lifting board to the desktop of the mahjong table. Since the lifting board is usually hinged to the desktop at one end, during the pushing process, the other end swings around the hinge axis to connect with the card discharging end of the card feeding track, and the connection part is lower than the desktop. The function of the lifting structure is to drive the lifting board to swing around the hinge axis so that the lifting board swings to connect with the card feeding track during card feeding and swings to be flush with the desktop after card feeding is completed.

[0057] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0058] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0059] In the description of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, an integral connection, or a detachable connection; it can be the internal connection of two components; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0060] like Figures 1-3 As shown, the mahjong machine of this embodiment is equipped with an integrated structure for stacking and raising cards, which is installed in a frame 400.

[0061] The stacking and raising structure of the present embodiment includes a driving motor 100, a stacking structure 200 and a raising structure 300. As the greatest improvement of the present embodiment, the stacking structure 200 and the raising structure 300 are both driven by a driving motor 100. The stacking structure 200 and the raising structure 300 are driven by the same driving motor, which reduces the number of motors. For the mahjong machine as a whole, since the stacking structure and the raising structure each have four groups, it is equivalent to reducing four motors, reducing the cost of motor and circuit control, and improving the stability of the system and lowering the failure rate.

[0062] Specifically to this embodiment, Figure 19 As shown, two one-way bearings are mounted side by side on the output shaft 110 of the driving motor 100, namely a first one-way bearing 350 and a second one-way bearing 351. The first one-way bearing 350 and the second one-way bearing 351 have opposite free rotation directions.

[0063] It should be noted that the one-way bearing is a mature product that can be directly purchased in the prior art. Its specific structure is not described in detail here. The function of the one-way bearing is that it can rotate freely in one direction and will be locked in the opposite direction, so as to transmit driving force. In addition, in the art, the one-way bearing also has other names, such as overrunning clutch, etc. Those skilled in the art should understand that any structure that can achieve rotation in one direction and lock in the other direction can be regarded as the one-way bearing of this application.

[0064] In this embodiment, the driving force of the card stacking structure 200 is provided by the driving motor 100 via the first one-way bearing 350 and the first transmission mechanism, and the driving force of the card lifting structure 300 is provided by the driving motor 100 via the second one-way bearing 351 and the second transmission mechanism, so that the driving motor 100 provides driving force for the card stacking structure 200 and the card lifting structure 300 in the forward rotation and reverse rotation states respectively.

[0065] In this way, one driving motor 100 provides driving force for both the card stacking structure 200 and the card lifting structure 300 at the same time. At the same time, the utilization rate of the driving motor 100 will be higher, and the integration degree of the system will be higher, making the layout of the mahjong machine more optimized and reasonable.

[0066] As Figure 3 、 Figure 4 As shown, the card stacking structure of this embodiment includes a card supporting seat 210 and a card pushing head 220, wherein the card supporting seat 210 is connected to the first one-way bearing 350 through the first transmission mechanism. Specifically, the first transmission mechanism in this embodiment includes a cam member 240 and a cam swing rod 260. The cam member 240 is connected to the output shaft 110 of the driving motor through the first one-way bearing 350. A first cam groove is provided on the side of the cam member 240 facing the driving motor. The first cam groove includes an equal-diameter section 241 and a convex section 242.

[0067] As Figure 4 、 Figure 10 As shown, one end of the cam swing rod 260 in this embodiment is provided with a hinged end 261, which is rotatably and movably connected to the frame 400. The cam swing rod can swing around the hinged end. The other end of the cam swing rod 260 is provided with a connection end 262 for connecting to the card supporting seat. A first connecting roller 263 adapted to be connected to the first cam groove is provided between the hinged end and the connection end of the cam swing rod 260.

[0068] In this embodiment, as Figure 4 shown, a card supporting and supporting plate 213 is provided at the bottom of the card supporting seat 210, and a connection groove 214 for connecting to the connection end 262 is provided on the card supporting and supporting plate 213. It should be noted that the projected area of the connection groove is larger than the projected area of the connection end, and the connection end 262 has a larger movement space in the connection groove 214.

[0069] In this embodiment, as Figure 2 、 Figure 3 shown, a vertical guiding mechanism is provided at the bottom of the card supporting seat 210. The vertical guiding mechanism includes a guiding block 211 provided at the bottom of the card supporting seat and a guiding groove 212 provided on the frame. The guiding block 211 and the guiding groove 212 cooperate with each other so that the card supporting seat can only move in the vertical direction.

[0070] In this embodiment, the card - receiving seat 210 has two working positions in the vertical direction. When in the Figure 5 high position shown, it is used to receive the first mahjong tile conveyed by the upper - card mechanism. When in the Figure 6 low position shown, it is used to receive the second mahjong tile and stack it on the first mahjong tile. The state of receiving 2 mahjong tiles is as shown in Figure 7 .

[0071] In this embodiment, in the Figure 5 high - position state shown, at this time, the first connecting roller 263 is at the highest point of the convex section 242. As the driving motor drives the cam member to rotate counter - clockwise, as shown in Figure 6 , the first connecting roller 263 moves to the equal - diameter section. At this time, the card - receiving seat is in the low position.

[0072] The card - pushing head 220 in this embodiment is provided with a card - pushing driving mechanism. In this embodiment, as shown in Figures 7-9 , when there are two mahjong tiles on the card - receiving seat and it is in the low position, the card - pushing driving mechanism drives the card - pushing head to pass above the card - receiving seat for pushing the mahjong tiles onto the upper - card track (not shown in the figure). It should be understood that although in this embodiment, the card - pushing head works when the card - receiving seat is in the low position, the card - pushing action can also be carried out when the card - receiving seat is in the high position.

[0073] The card - pushing driving mechanism of this embodiment, as shown in Figure 3 and Figures 7-9 , includes a slider 230. The slider 230 is connected to the card - pushing head 220 through a connecting bracket 221. The slider 230 is provided with a lateral guiding mechanism in the same direction as the moving direction of the card - pushing head. The lateral guiding mechanism includes a lateral guide rail 234 fixed to the frame and a lateral guiding groove 235 provided on the slider and adapted to be connected with the lateral guide rail 234.

[0074] In this embodiment, a second cam groove is provided on one side of the slider facing the cam member. The second cam groove at least includes a vertical straight section 231 and an arc section 232 connected to the lower end of the vertical straight section. In this embodiment, a small vertical straight section 233 is also provided at the lower end of the arc section 232.

[0075] In this embodiment, a second connecting roller 243 is provided on one side of the cam member facing the slider. The second connecting roller 243 is adapted to be connected with the second cam groove. And, the second connecting roller 243 is arranged deviating from the rotation center of the cam member, and the rotation radius of the second connecting roller is adapted to the arc section of the second cam groove.

[0076] In the above structure, as the cam member rotates, the driving slider moves linearly, driving the card-pushing head to move linearly. During the process of the card-bearing seat bearing the cards, the second connecting roller 243 is located within the arc section 232. Since the rotation radius of the second connecting roller matches the arc section of the second cam groove, when the second connecting roller 243 moves within the arc section 232, the card-pushing head remains stationary.

[0077] In this embodiment, the card-pushing action of the card-pushing head and the lifting of the card-bearing seat are integrated on the same driving motor. In this way, the integration degree of the mahjong machine system is higher, the utilization rate of the driving motor is higher, the internal structure layout of the mahjong machine is further optimized, the number of driving motors is reduced, the motor cost and circuit control cost are saved, and the failure rate is reduced.

[0078] As Figures 1-3 shown, in the mahjong machine of this embodiment, the configured card-lifting structure has a card-lifting plate 310, a swing rod member 320, a sliding member 330, and a driving structure for driving the sliding member 330 to move linearly.

[0079] Among them, as Figure 3 , Figure 11 shown, one end of the card-lifting plate 310 is provided with a hinge shaft 312, and the card-lifting plate is hinged to the tabletop 410 of the mahjong machine through this hinge shaft 312. When the card-lifting plate 310 is in a horizontal state, it is flush with the tabletop 410.

[0080] In this embodiment, as Figure 11 shown, a card-lifting connection portion 311 is provided at a position near the other end of the bottom of the card-lifting plate 310. At least one side of the card-lifting connection portion 311 is provided with a sliding track groove 313. Of course, the sliding track groove can also be provided through the card-lifting connection portion.

[0081] In this embodiment, the above-mentioned sliding track groove 313 has a high position end 332 and a low position end 331 and is continuous between the high position end and the low position end.

[0082] As Figure 12 shown, the swing rod member 320 of this embodiment includes a swing rod return shaft 323 and a first swing rod 321 and a second swing rod 322 respectively fixedly connected to both ends of the swing rod return shaft 323. Among them, as Figures 2-3 shown, the above-mentioned swing rod return shaft 323 is rotatably connected to a rotary seat 373, and the rotary seat 373 is fixedly connected to the inside of the frame 400.

[0083] In this embodiment, a third connecting roller 324 is provided at the free end of the first swing rod 321. As Figure 11 shown, the third connecting roller 324 is adaptively connected to the sliding track groove 313.

[0084] In this embodiment, a first sliding long groove 325 is provided at a position near the free end on one side of the second swing rod 322, and the length direction of the first sliding long groove 325 is substantially the same as the length direction of the second swing rod 322.

[0085] As Figure 13 shown, in this embodiment, the slider 330 is configured with a guide rail 331, which is usually horizontally arranged. Correspondingly, a guide groove adapted to the guide rail 331 is provided on the slider, and the two are slidably connected to each other.

[0086] In this embodiment, a fourth connecting roller 332 is provided on the slider 330, and the fourth connecting roller 332 is adaptively connected to the first sliding long groove 325.

[0087] In this embodiment, when the slider 330 is configured with a driving mechanism that can drive it to move along the length direction of the guide rail, the linear displacement of the slider is transmitted through the fourth connecting roller 332 and the first sliding long groove 325, driving the swing rod member 320 to swing around the swing rod shaft 323, and further driving the third connecting roller 324 to reciprocate between the high position end 332 and the low position end 331 of the sliding track groove 313. As Figure 16 、 Figure 17 shown, in the card-lifting state, the third connecting roller 324 is located at the low position end 331 of the sliding track groove 313, which can enable the mahjong tiles 500 to travel from the card-lifting track to the card-lifting plate 310.

[0088] After all the mahjong tiles on the card-loading track have traveled to the card-lifting plate, the slider moves horizontally, driving the third connecting roller 324 to travel from the low position end 331 along the sliding track groove 313 to the high position end 332, as Figure 14 、 Figure 15 shown, completing the card-lifting action of the mahjong tiles.

[0089] In this embodiment, a preferred driving mechanism is as Figure 18 shown, which includes a motor 100. A first gear 352 is connected to the output shaft 110 of the motor 100 through a second one-way bearing 351. The first gear 352 meshes with a second gear 353. A first bevel gear 354 is coaxially connected to the second gear 353, and a second bevel gear 355 meshes with the first bevel gear 354.

[0090] The driving mechanism of this embodiment is configured with a gear transmission mechanism. The gear transmission mechanism has the technical advantages of short transmission stroke and high transmission accuracy. At the same time, the transmission ratio can also be adjusted by the diameter and number of teeth of the gears. In addition, the bevel gear transmission also changes the power transmission direction, which is of great significance for optimizing the internal structure layout of this application.

[0091] In this embodiment, an eccentric wheel 340 coaxially connected to the second bevel gear 355 is provided. A fifth connecting roller 341 is provided on the eccentric wheel 340, and the axis of the fifth connecting roller is eccentrically arranged relative to the rotation axis of the eccentric wheel.

[0092] Correspondingly, in this embodiment, as Figure 13 , Figure 15 shown, on the side of the slider 330 facing the eccentric wheel, a second sliding long groove 333 is provided, and the fifth connecting roller 341 is adaptively connected to the second sliding long groove 333. The length direction of the second sliding long groove is arranged crosswise with the length direction of the guide rail.

[0093] In this way, the rotational motion of the eccentric wheel 340 drives the slider to move linearly along the guide rail through the power transmission between the fifth connecting roller 341 and the second sliding long groove 333.

[0094] In this embodiment, Figure 13 the shown implementation manner and Figure 15 the shown implementation manner give two different trajectory forms of the second sliding long groove 333. Among them, Figure 13 in the shown implementation manner, the second sliding long groove 333 extends in the vertical direction, Figure 15 in the shown implementation manner, the second sliding long groove 333 is a multi-segment connected trajectory groove. Of course, those skilled in the art should understand that the trajectory of the second sliding long groove 333 is not limited to the two implementation manners listed in this embodiment.

[0095] In the above structure, the swing rod, the slider and the gear transmission group constitute the second transmission mechanism of this embodiment. In this embodiment, the clockwise rotation of the output shaft of the motor provides the driving force for the card-lifting structure.

[0096] It should be noted that those skilled in the art should understand that in this embodiment, the structural forms of the first connecting roller, the second connecting roller, the third connecting roller, the fourth connecting roller and the fifth connecting roller can be either a roller-type structure, that is, it can rotate around the axial direction of the connecting roller itself, or a non-rotatable structure can be provided.

[0097] In summary, the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
