Description

TECHNICAL FIELD

[0001] The utility model relates to the field of automatic mahjong machine, especially the inclined card feeding device of automatic mahjong machine. BACKGROUND

[0002] The inclined card feeding device of the prior art mahjong machine (for reference, the Chinese utility model patent with the publication number CN207307151U and the name of a mahjong machine card lifting mechanism), usually adopts a driving motor to drive the card pushing head and the card lifting plate to move. Since the card pushing head and the card lifting plate need to move alternately to realize the card pushing and card feeding of the inclined card feeding device, the transmission structure between the driving motor and the card pushing head and the card lifting plate is very complex. The complex transmission structure not only increases the material cost, but also greatly increases the assembly difficulty.

[0003] In addition, the transmission structure between the driving motor and the card pushing head is difficult to lock the position of the card pushing head. When the card pushing head needs to support the mahjong tiles to lift the tiles, the mahjong tiles on the card lifting plate will slide downward during the process of the card lifting plate swinging upward from the inclined state to drive the mahjong tiles to rise. The sliding force of the mahjong tiles on the card lifting plate will make the card pushing head move backward together with the mahjong tiles. During the process of the mahjong tiles rising, the sliding mahjong tiles will be blocked by the table surface of the automatic mahjong machine, resulting in that the mahjong tiles cannot be lifted or the mahjong tiles are knocked off and fall back into the card pushing groove. SUMMARY

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an inclined card feeding device of an automatic mahjong machine. The inclined card feeding device of the prior art automatic mahjong machine adopts a driving motor to drive the card pushing head and the card lifting plate to move, which leads to the complex transmission structure between the driving motor and the card pushing head and the card lifting plate and the problem that the card pushing head is difficult to support the sliding mahjong tiles.

[0005] In order to realize the above technical target, the inclined card feeding device of the automatic mahjong machine provided by the utility model comprises: a card pushing mechanism, which comprises a card pushing motor, a card pushing groove and a card pushing part. The card pushing groove is used to store mahjong tiles. The card pushing part is driven to rotate by the card pushing motor to push the mahjong tiles in the card pushing groove.

In addition, the inclined card feeding device of the automatic mahjong machine further comprises:

[0006] a card lifting mechanism, which comprises a card lifting motor and a card lifting plate. The card lifting motor is used to drive the card lifting plate to swing and lift.

[0007] The card lifting motor and the card pushing motor are independently arranged. The card pushing mechanism further comprises an intermittent transmission structure. The intermittent transmission structure comprises a driving gear and a driven gear. The driving gear is driven by the card pushing motor.

[0009] The tilting tile feeding device is provided with the lifting tile plate and the tile pushing component which are independently driven by the lifting motor and the tile pushing motor, so that the lifting tile plate and the tile pushing component are driven to move, and the single motor is avoided from being required to drive the lifting tile plate and the tile pushing component to move through the complicated transmission structure between the lifting tile plate and the tile pushing component, the transmission structure is simplified, the material cost is reduced, and the assembly difficulty of the tilting tile feeding device is greatly reduced.

[0010] Preferably, the driving gear is further provided with a driving block, the driving block is driven to rotate with the driving gear, and the driving block drives the second positioning block to re-engage the driving gear, so that the driven gear re-engages the driving gear.

[0011] The driving block is arranged on the driving gear, so that the driving gear and the driven gear can re-engage from the non-engagement state, and the transmission structure between the driving gear and the driven gear is simplified.

[0012] Preferably, the center of the positioning convex arc surface is located on the rotation axis of the driving gear, and the radius of the rotation track of the outer end of the driving block is greater than the radius of the positioning convex arc surface.

[0013] The center of the positioning convex arc surface is coaxially arranged on the driving gear, so that at least one adjacent point on the positioning concave arc surface keeps the distance unchanged with the positioning convex arc surface when the positioning convex arc surface rotates with the driving gear, so that the rotation of the driving gear does not affect the locking effect of the positioning convex arc surface on the positioning concave arc surface, the reliability of the concave-convex cooperation of the positioning convex arc surface and the positioning concave arc surface for locking the driven gear is improved, meanwhile, the driving block is protrudingly arranged, the rotation track of the outer end of the driving block is beyond the rotation track of the positioning convex arc surface, the rotation of the driving block can directly abut on the second positioning block, and the second positioning block does not need to be provided with other structures matched with the driving block, so that the design of the second positioning block is simplified.

[0014] As preferred, the two circumferential side faces of the second positioning block are connected with the two ends of the positioning concave arc face to form two protrusions, and two avoiding grooves for avoiding the protrusions are circumferentially and spacedly arranged on the first positioning block.

[0015] By circumferentially and spacedly arranging two avoiding grooves on the left and right sides of the driving block of the first positioning block, the interference between the first positioning block and the second positioning block is avoided, and the cooperation movement of the first positioning block and the second positioning block is ensured.

[0016] As preferred, the positioning convex arc face, the groove wall of the two avoiding grooves and the side face of the driving block are connected to form a closed curved surface.

[0018] As preferred, the oblique card feeding device further comprises a first sensor, the first sensor detects the termination position of the card pushing movement of the card pushing component, and the first sensor is triggered in the concave-convex cooperation process of the positioning convex arc face and the positioning concave arc face.

[0019] By the foregoing technical solution, the card pushing motor is stopped by the first sensor when the card pushing component moves to the termination position, and the operation instruction of the card lifting motor is directly or indirectly issued, so that the oblique card feeding device can complete the card pushing and card lifting actions; since the driving gear and the driven gear are in the non-engagement state during the concave-convex cooperation of the positioning convex arc face and the positioning concave arc face, the first sensor is triggered in the concave-convex cooperation process of the positioning convex arc face and the positioning concave arc face, so that the card pushing head can be ensured to stay at the termination position, the operation accuracy of the card pushing head is improved, and the operation and control precision of the card pushing mechanism is improved.

[0020] As preferred, the positioning convex arc face is a superior arc face, and the positioning concave arc face is an inferior arc face.

[0021] By the foregoing technical solution, the driving gear needs to rotate a large amplitude to release the locking state of the driving gear and the driven gear, so that even if the first sensor has a large delay or the signal for controlling the card pushing motor has a large delay, the driving gear in the non-engagement state can still lock the driven gear, and the reliability of the driving gear in the non-engagement state to lock the driven gear is improved.

[0022] As preferred, the oblique card feeding device further comprises a second sensor, the second sensor detects the starting position of the card pushing movement of the card pushing component, and the second sensor and the first sensor are installed on the same circuit board.

[0023] The second sensor detects the starting position of the pushing movement of the pushing component, so that the inclined tile feeding device can recognize the movement of the pushing component, and the action of the inclined tile feeding device and the corresponding components of the automatic mahjong machine can be controlled according to the preset program. The first sensor and the second sensor are installed on the same circuit board, and the two sensors are assembled in one assembly process, thereby saving the assembly cost.

[0024] Preferably, the driven gear includes a toothed segment and a toothless segment, the driving gear is engaged with the toothed segment to drive the driven gear to rotate synchronously, the driving gear is disengaged from the toothless segment to make the driven gear stop rotating intermittently, and the positioning concave arc surface corresponds to the toothless segment in the axial direction of the driven gear.

[0025] When the driving gear is engaged with the toothed segment, the driving gear can drive the driven gear to rotate and drive the pushing component to push the tiles. With the rotation of the driven gear, the toothless segment rotates to the position adjacent to the driving gear, so that the driven gear is disengaged from the driving gear and enters the stationary state, and the pushing component is stationary. The number of teeth of the driving gear is less than that of the driven gear, and the toothless segment is arranged on the driven gear, so that the driven gear rotates one revolution and is intermittently driven by the driving gear only once, thereby avoiding the pushing mechanism from making intermittent movement multiple times in one pushing movement process and reducing the pushing efficiency.

[0026] Preferably, the inclined tile feeding device further includes a third sensor, which detects the stopping position of the mahjong tiles in the pushing groove before the tiles are lifted.

[0027] The third sensor is arranged to control the final position of the mahjong tiles in the pushing groove before the tiles are lifted, so that the mahjong tiles of different numbers and sizes are stopped at the same position before the tiles are lifted, the lifting time of the different mahjong tiles is ensured to be the same, and the consistency of the overall shuffling time of the different mahjong tiles is achieved.

[0028] Preferably, the inclined tile feeding device further includes a pushing base, an outer ring baffle and an inner ring baffle, the outer ring baffle and the inner ring baffle are installed on the pushing base to form the pushing groove, and the pushing motor, the lifting motor and the intermittent transmission structure are installed in the part of the pushing base surrounded by the inner ring baffle.

[0029] The pushing motor, the lifting motor and the intermittent transmission structure are installed in the part of the pushing base surrounded by the inner ring baffle, so as to avoid occupying the space outside the pushing base, thereby reducing the space occupied by the inclined tile feeding device on the mahjong machine, and making the components on the mahjong machine more compact.

[0030] As preferred, the tile pushing component comprises a tile pushing arm, a rotating seat arranged at the inner end of the tile pushing arm, and a tile pushing head arranged at the outer end of the tile pushing arm, the rotating seat is coaxially connected with the driven gear, and the tile pushing head extends into the tile pushing groove.

[0031] As preferred, the tile lifting mechanism further comprises a tile lifting rocker, a tile lifting connecting rod, and a tile lifting cam with a cam curved guide groove, the tile lifting cam is drivingly connected with the tile lifting motor, one end of the tile lifting connecting rod relatively slides along the cam curved guide groove, the other end of the tile lifting connecting rod is drivingly connected with the tile lifting rocker, and the tile lifting rocker drives the tile lifting plate to swing up and down.

[0032] By using the above technical scheme, the cam curved guide groove of the tile lifting cam cooperates with the tile lifting connecting rod and the tile lifting rocker to realize the lifting of the tile lifting plate, so that the tile pushing component pushes the mahjong tiles onto the tile lifting plate.

Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more of the features.

[0061] As Figures 1 to 12 Indicated, the embodiment of the utility model proposes automatic mahjong machine, including bottom plate 20, control panel in the central of bottom plate 20, wash big dish 30, wash barrel 40 and four group of card sorting device, wash big dish 30 is located wash barrel 40 part and can rotate relative to wash barrel 40, and four group of card sorting device is arranged around the circumference of wash barrel 40.Wash card sorting device includes card sucking device 50, card stacking device 60 and inclined card feeding device 10.Inclined card feeding device 10 is equipped with the card pushing groove 114 of arc bending, and the card pushing groove 114 includes card inlet 1141 and card outlet 1142, and the card pushing groove 114 is bent from card inlet 1141 to card outlet 1142 and is bent into the arc structure of the bending angle greater than 180 °.Card sucking device 50 absorbs mahjong tiles from the card sucking big dish one by one and sends to card stacking device 60, and card stacking device 60 is used to stack two mahjong tiles into a pile and push into the card pushing groove 114.

[0062] In other some embodiments, the card stacking action of the stacking and pushing device for stacking two mahjong tiles into a pile and the card pushing action for pushing the mahjong tiles stacked into a pile into the card pushing groove 114 can be completed by two relatively independent devices.

[0063] As Figures 1 to 9 Indicated, inclined card feeding device 10 includes card pushing mechanism 100 and card lifting mechanism 200.Card pushing mechanism 100 includes card pushing bracket 110, card pushing motor 120 and card pushing part 130, and card pushing part 130 includes card pushing head 131 for pushing mahjong tiles in card pushing groove 114.Card pushing bracket 110 is equipped with the card pushing groove 114 for storing mahjong tiles, specifically, card pushing bracket 110 further includes card pushing base 111, outer ring baffle 112 and inner ring baffle 113, and outer ring baffle 112 and inner ring baffle 113 are installed on card pushing base 111, and outer ring baffle 112 and inner ring baffle 113 and card pushing base 111 form card pushing groove 114.The outer ring baffle 112 and the inner ring baffle 113 limit the movement trajectory of mahjong tiles in the card pushing groove 114, and the spacing between the outer ring baffle 112 and the inner ring baffle 113 enables the smooth movement of mahjong tiles between them.

[0064] The outer ring baffle 112 and the pushing base 111 can be formed separately and connected by fasteners such as screws, buckles, etc. The outer ring baffle 112 and the pushing base 111 can also be integrally formed, such as being integrally injection molded plastic parts or being integrally connected by secondary injection molding.

[0065] The card lifting mechanism 200 includes a card lifting support, a card lifting motor 210, and a card lifting plate 220. The card lifting plate 220 is rotationally connected to the card lifting support, and the card lifting motor 210 is configured to drive the card lifting plate 220 to swing up and down. The card lifting plate 220 swings down to connect to the card outlet 1142. The pushing part 130 pushes the mahjong tiles onto the card lifting plate 220. The card lifting plate 220 swings up to lift the mahjong tiles to the table surface of the automatic mahjong machine.

[0066] The automatic mahjong machine has four sets of card sorting devices, which are independently arranged without overlapping each other. In any one set of card sorting device, the card lifting mechanism 200 is arranged on the inner side of the tile suction device 50 in the same set of card sorting device and is adjacent to the tile suction device 50. The card lifting mechanism 200 and the tile suction device 50 are arranged on the outer side of the arc-shaped bending of the pushing groove 114. The pushing part 130 of the pushing mechanism 100 is arranged on the inner side of the arc-shaped bending of the pushing groove 114. The tile stacking device 60 is arranged between the tile suction device 50 and the pushing support 110. In this way, the card lifting mechanism 200 and the tile suction device 50 in the same set of card sorting device are adjacent to each other, so that the pushing groove 114 can be arc-shapedly bent at a large angle, the length of the pushing groove 114 is extended, and the storage amount of the mahjong tiles in the pushing groove 114 is increased. The card lifting mechanism 200 and the tile suction device 50 are arranged on the outer side of the arc-shaped bending of the pushing groove 114, and the pushing part 130 of the pushing mechanism 100 is arranged on the inner side of the arc-shaped bending of the pushing groove 114, so as to reduce or avoid the overlapping of the tile feeding device and the inclined tile feeding device 10 in the height direction, and reduce the overall height of the mahjong machine. The four sets of card sorting devices are independently arranged without overlapping each other. The position of the card lifting outlet can be moved to the inner side of the mahjong machine panel. After the tiles are fed, the players do not need to push the mahjong tile wall to leave the playing position.

[0067] In the prior art, the pushing part 130 and the card lifting plate 220 are driven by one motor. However, the transmission structure between the motor and the pushing part 130 and the card lifting plate 220 is complex, which leads to an increase in cost. For details, please refer to the Chinese Utility Model Patent No. CN207307151U, entitled "Mahjong Machine Card Lifting Mechanism".

[0068] In the present embodiment, as shown in FIG. 1, the card lifting motor 210 and the pushing motor 120 of the inclined tile feeding device 10 are independently arranged. The card lifting motor 210 drives the card lifting plate 220 to move, and the pushing motor 120 drives the pushing part 130 to move. Figures 1 to 7 The inclined tile feeding device 10 further includes a control module, which controls the operation of the card lifting motor 210 and the pushing motor 120.

[0069] The automatic mahjong machine of the embodiment has a multi-stage dealing method, which includes a first dealing stage and a second dealing stage. In the first dealing stage, the pushing head 131 pushes six stacks of mahjong tiles in the pushing groove 114 onto the lifting plate 220, and the pushing head 131 is in contact with the mahjong tiles to prevent the mahjong tiles from sliding off the lifting plate 220. In the second dealing stage, the pushing head 131 pushes the remaining twelve stacks of mahjong tiles in the pushing groove 114 onto the lifting plate 220, and the pushing head 131 is still in contact with the mahjong tiles. Referring to Figure 3 , the pushing head 131 rotates in the counterclockwise direction. The multi-stage dealing method of the embodiment will be described in subsequent embodiments.

[0070] It should be noted that the description of pushing six stacks of mahjong tiles first and then pushing twelve stacks of mahjong tiles is for illustrative purposes to describe the multi-stage dealing process. In the game set by the automatic mahjong machine, the number of stacks of mahjong tiles pushed first and then pushed can be adjusted as needed.

[0071] When the lifting plate 220 is not lifted or is in the process of being lifted, the lifting plate 220 is in an inclined state, and the mahjong tiles on the lifting plate 220 have a tendency to slide downward. Since the driving gear 310 cannot completely lock the position of the driven gear 320, that is, the pushing component 130 will move backward under the action of the downward sliding force of the mahjong tiles, causing the mahjong tiles to slide backward during the lifting of the lifting plate 220, resulting in the mahjong tiles being blocked by the table surface of the automatic mahjong machine during the lifting of the mahjong tiles, which prevents the mahjong tiles from being lifted or the mahjong tiles from being knocked back into the pushing groove 114.

[0072] In order to achieve the locking of the driving gear 310 to the driven gear 320 and to prevent the mahjong tiles from sliding downward, in the embodiment, as shown in Figures 1 to 6 , the pushing mechanism 100 further includes an intermittent transmission structure 300, which includes a driving gear 310 and a driven gear 320. The driving gear 310 is driven by the pushing motor 120, and the driven gear 320 is drivingly connected to the pushing component 130. The driven gear 320 is configured as an incomplete gear to intermittently engage the driving gear 310. The driving gear 310 is provided with a first positioning block 311 that rotates synchronously, and the first positioning block 311 has a positioning convex arc surface 312. The driven gear 320 is provided with a second positioning block 321 that rotates synchronously, and the second positioning block 321 has a positioning concave arc surface 322. The driving gear 310 and the driven gear 320 are in a non-engaged state, and the positioning convex arc surface 312 and the positioning concave arc surface 322 are in concave-convex cooperation to lock the driven gear 320 in the non-engaged state.

[0073] The driven gear 320 is in meshing state with the driving gear 310, the pusher motor 120 drives the pusher component 130 to move, and the pusher component 130 pushes the mahjong tiles in the pusher groove 114 to move. The driven gear 320 is in non-meshing state with the meshing driving gear 310, the transmission between the driven gear 320 and the meshing driving gear 310 is cut off, so that the pusher component 130 stops moving. At this time, the positioning convex arc surface 312 and the positioning concave arc surface 322 are in concave-convex cooperation, so that the positioning convex arc surface 312 blocks the rotation path of the positioning concave arc surface 322 and limits the rotation of the positioning concave arc surface 322. The sliding force of the mahjong tiles cannot drive the driven gear 320 to rotate. The concave-convex cooperation between the positioning convex arc surface 312 and the positioning concave arc surface 322 locks the driven gear 320 in the non-meshing state, so that the pusher head 131 cannot move backward to avoid the sliding of the mahjong tiles.

[0074] In the concave-convex cooperation between the positioning convex arc surface 312 and the positioning concave arc surface 322, no gap is provided between them, and the driving gear 310 has a frictional rotation relative to the driven gear 320. In this way, in the non-meshing state, the positioning convex arc surface 312 can completely lock the positioning concave arc surface 322 so that the driven gear 320 cannot rotate. However, due to machining precision and assembly error, it is difficult to avoid that the positioning convex arc surface 312 and the positioning concave arc surface 322 have a gap at least in part of the position, but this part of the gap does not affect the locking of the positioning convex arc surface 312 on the positioning concave arc surface 322.

[0075] Due to the concave-convex cooperation between the positioning convex arc surface 312 on the driving gear 310 and the positioning concave arc surface 322 on the driven gear 320, the locking of the driving gear 310 on the driven gear 320 is realized, so that the pusher head 131 is prevented from being pushed by the sliding force of the mahjong tiles during the lifting of the mahjong tiles. However, if the driving gear 310 and the driven gear 320 always remain in the meshing state, the positioning convex arc surface 312 and the positioning concave arc surface 322 cannot be rotated into the matching position of the two. Therefore, the driving gear 310 and the driven gear 320 are arranged to be gapingly meshed.

[0076] Reference Figure 4When the driving gear 310 and the driven gear 320 are just disengaged or about to engage, the positioning convex arc surface 312 and the positioning concave arc surface 322 are in contact with each other but not in the concave-convex matching state, and the continuous rotation of the driving gear 310 causes the positioning convex arc surface 312 to act on the positioning concave arc surface 322 to drive the driven gear 320 to continue rotating, at this time, the rotation speed of the driven gear 320 is less than that in the engaged state, and the positioning convex arc surface 312 and the positioning concave arc surface 322 gradually enter the concave-convex matching state. After the positioning convex arc surface 312 and the positioning concave arc surface 322 enter the concave-convex matching state, the driven gear 320 stops rotating. In the concave-convex matching state of the positioning convex arc surface 312 and the positioning concave arc surface 322, the arc surfaces of the positioning convex arc surface 312 and the positioning concave arc surface 322 are concentric, the positioning convex arc surface 312 can rotate relative to the positioning concave arc surface 322 around its own center, but the positioning concave arc surface 322 cannot rotate around its own center and is thus locked by the positioning convex arc surface 312.

[0077] The inclined tile device 10 of the utility model, through setting up the tile lifting motor 210 and the tile pushing motor 120 independently, the tile lifting motor 210 and the tile pushing motor 120 drive the tile lifting plate 220 and the tile pushing component 130 to move respectively, which avoids the single motor driving the tile lifting plate 220 and the tile pushing component 130 to move, and the motor needs to drive between the tile lifting plate 220 and the tile pushing component 130 through the complicated transmission structure, simplifies the transmission structure, reduces the material cost, and greatly reduces the assembly difficulty of the inclined tile device 10. Secondly, through the intermittent engagement transmission of the driving gear 310 and the driven gear 320 in the tile pushing mechanism 100, the driving gear 310 and the driven gear 320 are locked through the concave-convex matching of the positioning convex arc surface 312 and the positioning concave arc surface 322 in the non-engagement state, which avoids the backward movement of the tile pushing component 130 under the sliding force of the mahjong tiles, makes the tile pushing component 130 resist the mahjong tiles in the tile lifting process of the tile lifting plate 220, reduces the sliding amplitude of the mahjong tiles on the tile lifting plate 220, and improves the reliability and stability of the inclined tile device 10 in lifting the mahjong tiles.

[0078] In the embodiment, as shown in FIG. 1, Figures 1 to 9 The tile pushing motor 120, the tile lifting motor 210 and the intermittent transmission structure 300 are installed in the part surrounded by the inner ring baffle 113 on the tile pushing base 111. By installing the tile pushing motor 120, the tile lifting motor 210 and the intermittent transmission structure 300 in the part surrounded by the inner ring baffle 113 on the tile pushing base 111, the tile pushing motor 120, the tile lifting motor 210 and the intermittent transmission structure 300 avoid occupying the space on the periphery of the tile pushing base 111, thereby reducing the space occupied by the inclined tile device 10 on the mahjong machine, and making the components on the mahjong machine more compact.

[0079] In some other embodiments, the pushing motor 120, the lifting motor 210 and the intermittent transmission structure 300 can also be installed at other positions of the pushing base 111.

[0080] In the present embodiment, as shown in Figures 1 to 6 the pushing member 130 further comprises a pushing arm 132, a rotating seat 133 arranged at the inner end of the pushing arm 132, and a pushing head 131 arranged at the outer end of the pushing arm 132. The rotating seat 133 is coaxially connected with the driven gear 320, and the pushing head 131 extends into the pushing groove 114. The rotation of the driven gear 320 drives the rotating seat 133 to rotate, and the rotation of the rotating seat 133 drives the pushing head 131 in the pushing groove 114 to move through the pushing arm 132. The movement of the pushing head 131 pushes the mahjong tiles in the pushing groove 114 to move towards the dealing opening 1142.

[0081] In the present embodiment, as shown in Figures 7 to 9 the lifting mechanism 200 further comprises a lifting rocker arm 230, a lifting connecting rod 240 and a lifting cam 260 with a cam curved guide groove 263. The lifting cam 260 is drivingly connected with the lifting motor 210. One end of the lifting connecting rod 240 relatively slides along the cam curved guide groove 263. The other end of the lifting connecting rod 240 is drivingly connected with the lifting rocker arm 230, and the lifting rocker arm 230 drives the lifting plate 220 to swing and lift.

[0082] The lifting connecting rod 240 is engaged with the lifting rocker arm 230. The lifting rocker arm 230 comprises an arm lever portion 231 connected with the lifting plate 220 and a rotating shaft portion 232 fixedly connected with the arm lever portion 231. The rotating shaft portion 232 is provided with teeth engaged with the lifting connecting rod 240. The lifting connecting rod 240 is guidedly moved in the pushing base 111, so that the lifting connecting rod 240 reciprocates along a straight line direction under the driving of the lifting cam 260. The lifting connecting rod 240 drives the rotating shaft portion 232 to rotate through the engagement with the rotating shaft portion 232. When the rotating shaft portion 232 rotates, the arm lever portion 231 connected with the rotating shaft portion 232 also swings. When the arm lever portion 231 swings, the end thereof connected with the lifting plate 220 changes in position in the length direction of the lifting plate 220. The lifting plate 220 can only flip up and down relative to the tabletop of the mahjong machine. Therefore, a notch 221 is arranged on the lower surface of the lifting plate 220. The arm lever portion 231 extends into the notch 221 and can freely move in the notch 221. When the arm lever portion 231 swings, the change in the vertical position of the arm lever portion 231 pushes the bottom wall or the top wall of the notch 221 to drive the lifting plate 220 to swing with the arm lever portion 231.

[0083] The lifting mechanism 200 further comprises a lifting gear 250 coaxially connected with the lifting cam 260, and the rotation of the lifting motor 210 drives the lifting gear 250 to rotate. The lifting cam 260 is provided with a cam-shaped structure and a surrounding edge 262 surrounding the cam-shaped structure 261, and a cam curved guide groove 263 is formed between the surrounding edge 262 and the outer side edge of the cam-shaped structure 261. The one end of the lifting connecting rod 240 extending into the cam curved guide groove 263 is sleeved with a rotatable roller 241, and the roller 241 is a sleeve or a bearing to reduce the wear between the lifting connecting rod 240 and the cam curved guide groove 263 when the cam curved guide groove 263 rotates.

[0084] The cam curved guide groove 263 comprises a lifting section 2631, a descending section 2632 and a transition section 2633 connected between the lifting section 2631 and the descending section 2632. In the rotation direction of the roller 241, the straight line distance between the lifting section 2631 and the rotation axis of the lifting cam 260 gradually increases, the straight line distance between the descending section 2632 and the rotation axis of the lifting cam 260 gradually decreases, and the straight line distance between the transition section 2633 and the rotation axis of the lifting cam 260 remains unchanged. When the roller 241 enters the descending section 2632, as the lifting gear 250 continues to rotate, the distance between the roller 241 and the rotation axis of the lifting gear 250 gradually decreases, driving the lifting connecting rod 240 to move towards the lifting cam 260, and the movement of the lifting connecting rod 240 drives the arm lever 231 to swing, causing the lifting plate 220 to descend. When the roller 241 enters the transition section 2633, the distance between the roller 241 and the rotation axis of the lifting gear 250 remains unchanged, the lifting connecting rod 240 remains stationary, and the lifting plate 220 is in a descending stationary state. When the roller 241 enters the lifting section 2631, the distance between the roller 241 and the rotation axis of the lifting gear 250 gradually increases, driving the lifting connecting rod 240 to move away from the lifting cam 260, and the movement of the lifting connecting rod 240 drives the arm lever 231 to swing, causing the lifting plate 220 to ascend, completing the lifting of the mahjong tiles.

[0085] Through the above arrangement, the cam curved guide groove 263 of the lifting cam 260 cooperates with the lifting connecting rod 240 and the lifting rocker arm 230 to realize the lifting and descending of the lifting plate 220, so as to cooperate with the tile pushing component 130 to push the mahjong tiles onto the lifting plate 220.

[0086] The lifting motor 210 can be directly connected to the lifting gear 250, or a transmission gear can be installed on the lifting motor 210, and the transmission gear meshes with the lifting gear 250.

[0087] In one embodiment, based on the inclined tile lifting device 10 of the foregoing embodiment, the inclined tile lifting device 10 further comprises a lifting motor 210 connected to the lifting gear 250. Figures 1 to 6As shown, the driving gear 310 is further provided with a driving block 313, which rotates with the driving gear 310 to drive the second positioning block 321, so that the driven gear 320 re-engages with the driving gear 310. The driving block 313 rotates with the driving gear 310 to rotate against the second positioning block 321, so that the rotation force of the driving gear 310 is transmitted to the driven gear 320 through the driving block 313 and the second positioning block 321, so that the driven gear 320 rotates with the driving block 313, and the rotation of the driven gear 320 makes the driven gear 320 and the driving gear 310 disengage from the non-engagement state to the engagement state, and the driven gear 320 rotates with the driving gear 310. As shown in Figure 4 , Figure 5 , the driving gear 310 rotates clockwise, and the driven gear 320 rotates counterclockwise.

[0088] In order to ensure the locking reliability of the driven gear 320 in the non-engagement state, as shown in Figures 1 to 6 , the center of the positioning convex arc surface 312 is located on the rotation axis of the driving gear 310. The positioning convex arc surface 312 is coaxially arranged with the driving gear 310, so that at least one adjacent point on the positioning concave arc surface 322 maintains the same distance with the positioning convex arc surface 312 when the positioning convex arc surface 312 rotates with the driving gear 310. Thus, the rotation of the driving gear 310 does not affect the locking effect of the positioning convex arc surface 312 on the positioning concave arc surface 322, and the reliability of the positioning convex arc surface 312 and the positioning concave arc surface 322 in locking the driven gear 320 is improved. As shown in Figure 4 , Figure 5 , the driving gear 310 rotates clockwise, and the driven gear 320 rotates counterclockwise.

[0089] In order to improve the driving reliability of the driving block 313 on the second positioning block 321, as shown in Figures 1 to 6 , the driving block 313 is protruded relative to the positioning convex arc surface 312, and the radius of the rotation track of the outer end of the driving block 313 is greater than the radius of the positioning convex arc surface 312. Due to the protruding arrangement of the driving block 313, the rotation track of the outer end of the driving block 313 exceeds the rotation track of the positioning convex arc surface 312, and the rotation of the driving block 313 can directly abut against the second positioning block 321, so that the second positioning block 321 does not need to have other structures matched with the driving block 313, and the design of the second positioning block 321 is simplified.

[0090] In one embodiment, based on the tilt card device 10 of the foregoing embodiment, as shown in Figures 1 to 6As shown, the circumferential two sides of the second positioning block 321 are connected with the two ends of the positioning concave arc surface 322 to form two protrusions 323, and the first positioning block 311 is provided with two avoiding grooves 314 for avoiding the protrusions 323 at intervals in the circumferential direction, and the two avoiding grooves 314 are spaced apart by the driving block 313.

[0091] Reference Figure 4 、 Figure 5 The driving gear 310 rotates clockwise, and the driven gear 320 rotates counterclockwise. In the figure, the avoiding groove 314 avoids the protrusion 323 on the right side of the positioning concave arc surface 322, so as to avoid the interference between the first positioning block 311 and the second positioning block 321. At this time, the driven gear 320 and the driving gear 310 are about to enter the non-engagement state, and the driving gear 310 keeps rotating. After entering the non-engagement state, the driven gear 320 stops rotating due to the lack of power. In the figure, the avoiding groove 314 avoids the protrusion 323 on the left side of the positioning concave arc surface 322, and the driving block 313 is about to drive the second positioning block 321, so that the driven gear 320 and the driving gear 310 restore the engagement state.

[0092] By providing the two avoiding grooves 314 at intervals in the circumferential direction on the left and right sides of the driving block 313 of the first positioning block 311, the interference between the first positioning block 311 and the second positioning block 321 is avoided, and the cooperation movement of the first positioning block 311 and the second positioning block 321 is ensured.

[0093] In an embodiment, based on the tilting card feeding device 10 of the foregoing embodiment, as shown in Figure 4 、 Figure 5 The positioning convex arc surface 312, the groove walls of the two avoiding grooves 314, and the side surfaces of the driving block 313 are connected to form a closed curved surface. In this way, the friction in the cooperation movement of the first positioning block 311 and the second positioning block 321 is reduced, and the cooperation movement of the first positioning block 311 and the second positioning block 321 is smoother.

[0094] In an embodiment, based on the tilting card feeding device 10 of the foregoing embodiment, as shown in Figure 2As shown, the driven gear 320 includes a toothed section 324 and a toothless section 325, the driving gear 310 engages with the toothed section 324 to drive the driven gear 320 to rotate synchronously, and the driving gear 310 disengages with the toothless section 325 to make the driven gear 320 stop rotating intermittently. The positioning concave arc surface 322 corresponds to the toothless section 325 in the axial direction of the driven gear 320. When the driving gear 310 engages with the toothed section 324, the driven gear 320 can be driven to rotate to drive the pushing component 130 to push the mahjong tiles. With the rotation of the driven gear 320, the toothless section 325 rotates to the position adjacent to the driving gear 310, so that the driven gear 320 disengages with the driving gear 310, and the pushing component 130 is in a stationary state. The number of teeth of the driving gear 310 is less than that of the driven gear 320, and the toothless section 325 is arranged on the driven gear 320, so that the driven gear 320 rotates one revolution only once to drive the driving gear 310 intermittently, avoiding the pushing mechanism 100 from making intermittent movement multiple times in one pushing movement to cause the pushing efficiency to decrease.

[0095] In one embodiment, the inclined tile feeding device 10 based on the foregoing embodiment, as shown in Figure 7 The inclined tile feeding device 10 further includes a first sensor 11, which detects the end position of the pushing movement of the pushing component 130, and the first sensor 11 is triggered in the concave-convex matching process of the positioning convex arc surface 312 and the positioning concave arc surface 322.

[0096] The first sensor 11 can directly detect the pushing component 130 or indirectly detect the pushing component 130. For example, the relative position of the pushing component 130 relative to the pushing groove 114 is directly detected to obtain the position information of the pushing component 130 relative to the pushing groove 114, for example, the relative position of the inner ring baffle 113 relative to the pushing component 130 is directly detected to obtain the position information of the pushing groove 114 relative to the pushing component 130, for example, a stepping motor or a motor with a position sensor is used, and the rotation stroke information of the motor is recorded to indirectly obtain the position information of the pushing component 130 through conversion. The first sensor 11 can also be a sensor arranged in the pushing groove 114 to count the number of passing mahjong tiles, and the position information of the pushing component 130 is indirectly obtained by detecting the number of passing mahjong tiles. The above-mentioned sensors can be various proximity sensors such as Hall sensors, photoelectric sensors, ultrasonic sensors, etc., or various contact sensors such as limit switches.

[0097] The first sensor 11 detects that the pushing component 130 is in the terminal position of the pushing movement, which means that the pushing component 130 has pushed the mahjong tiles to the lifting plate 220, and the control module sends a stop signal to the pushing mechanism 100 or the pushing motor 120, or the control module cuts off the power supply of the pushing motor 120, so that the pushing mechanism 100 stops moving. At this time, the lifting mechanism 200 waits for a lifting instruction to lift the mahjong tiles to the table surface of the automatic mahjong machine. The lifting instruction can be an operation instruction of the lifting motor 210 automatically sent by the control module after receiving the detection signal of the first sensor 11, or a corresponding prompt displayed on the control panel of the automatic mahjong machine, and the operation instruction of the lifting motor 210 is sent after the user triggers the lifting instruction on the control panel of the automatic mahjong machine.

[0098] By setting the first sensor 11, the pushing motor 120 can be stopped when the pushing component 130 moves to the terminal position, and the operation instruction of the lifting motor 210 can be directly or indirectly sent, so that the inclined tile lifting device 10 can complete the pushing and lifting actions. Since the convex arc surface 312 and the concave arc surface 322 are in the non-engagement state when they are matched, the first sensor 11 is triggered during the matching process of the convex arc surface 312 and the concave arc surface 322, which can ensure that the pushing head 131 stays in the terminal position, improve the operation accuracy of the pushing head 131, and improve the operation and control precision of the pushing mechanism 100.

[0099] In the embodiment, as shown in Figure 4 , Figure 5 The convex arc surface 312 is a superior arc surface, and the concave arc surface 322 is an inferior arc surface. In this way, the driving gear 310 needs to rotate a large amplitude to release the locking state of the driving gear 310 and the driven gear 320. Even if the first sensor 11 has a certain delay or the signal for controlling the pushing motor 120 has a certain delay, the driving gear 310 in the non-engagement state can still lock the driven gear 320, which improves the reliability of the driving gear 310 locking the driven gear 320 in the non-engagement state.

[0100] In one embodiment, based on the inclined tile lifting device 10 of the foregoing embodiment, as shown in Figure 7 The inclined tile lifting device 10 further comprises a second sensor 12, which detects the starting position of the pushing movement of the pushing component 130. The second sensor 12 and the first sensor 11 are installed on the same circuit board.

[0101] In the embodiment, the pushing component 130 can be one-way rotating, and after the pushing component 130 finishes pushing the mahjong tiles in the pushing groove 114, the pushing component 130 continues to rotate in the pushing direction to return to the starting position. The pushing base 111 is disconnected between the tile outlet 1142 and the tile inlet 1141, and the pushing head 131 can move from the tile outlet 1142 to the tile inlet 1141 in the pushing direction. The pushing component 130 can also be reciprocating, and the pushing component 130 moves from the terminal position to the starting position of the pushing component 130 in the reverse rotating direction of the pushing direction, and the pushing head 131 returns to between the tile outlet 1142 and the tile inlet 1141.

[0102] When the second sensor 12 detects that the pushing component 130 is in the starting position, the second sensor 12 sends a corresponding detection signal to the control module. When there are still mahjong tiles in the pushing groove 114, the detection signal of the second sensor 12 means that the tilting tile feeding device 10 needs to complete the second stage pushing of the stage pushing, and the tilting tile feeding device 10 waits for the next pushing and tile lifting program instruction. The specific working process and principle of the stage pushing are described in detail in subsequent embodiments. When there are no mahjong tiles in the pushing groove 114, the detection signal of the second sensor 12 means that the automatic mahjong machine can perform tile shuffling, tile picking, tile stacking, and pushing the stacked mahjong tiles from the tile inlet 1141 into the pushing groove 114.

[0103] The first sensor 11 and the second sensor 12 are installed on the same circuit board but at different positions on the same circuit board. The first sensor 11 and the second sensor 12 can be Hall elements, which are triggered by the same magnetic element on the pushing component 130 at different positions, or different magnetic core elements on the pushing component 130, so as to detect the position of the pushing component 130. The first sensor 11 and the second sensor 12 can also be photoelectric sensors, and the pushing component 130 is provided with a through hole. The first sensor 11 and the second sensor 12 cooperate to detect the position of the pushing component 130. For example, the pushing component 130 is provided with a through hole, and the through hole corresponds to the first sensor 11 and the second sensor 12 at different positions, or different through holes correspond to the first sensor 11 and the second sensor 12. When the pushing component 130 is in the terminal position, the second sensor 12 is blocked by the pushing component 130, and the first sensor 11 corresponds to the through hole to detect that the pushing component 130 is in the terminal position. When the pushing component 130 is in the starting position, the first sensor 11 is blocked by the pushing component 130, and the second sensor 12 corresponds to the through hole to detect that the pushing component 130 is in the starting position.

[0104] By using the second sensor 12 to detect the starting position of the card-pushing component 130, the tilting card-feeding device 10 can identify the movement of the card-pushing component 130, thereby controlling the movement of the tilting card-feeding device 10 and the corresponding parts of the automatic mahjong machine according to the preset program. The first sensor 11 and the second sensor 12 are mounted on the same circuit board, and the two sensors are assembled in one assembly process, saving assembly costs.

[0105] In one embodiment, the tilting license plate issuing device 10 further includes a third sensor 13, such as Figure 1 , Figure 3 As shown, the third sensor 13 detects the position of the mahjong tiles in the pusher slot 114 before the tiles are lifted. When the number of mahjong tiles in the pusher slot 114 reaches a set value, the pusher component 130 pushes the mahjong tiles toward the outlet 1142 of the pusher slot 114. When the first stack of mahjong tiles is pushed, triggering the third sensor 13, the control module controls the pusher motor 120 to stop operating, and the mahjong tiles remain in the pusher slot 114.

[0106] The third sensor 13 can be disposed on the tile pusher base 111 to detect whether there is a mahjong tile at the resting position on the tile pusher base 111. The third sensor 13 can also be disposed inside the inner ring baffle 113 to detect whether there is a mahjong tile at the resting position in the tile pusher groove 114. The third sensor 13 can also be disposed outside the outer ring baffle 112. The third sensor 13 is preferably a photoelectric sensor, but it can also be a micro switch. In addition, since the mahjong tiles in the automatic mahjong machine contain magnets, the third sensor 13 can also be a Hall element.

[0107] By setting the third sensor 13, the final position of the mahjong tiles in the tile-pushing slot 114 before the tiles are raised can be controlled, so that mahjong tiles of different numbers and sizes stay in the same position before the tiles are raised, ensuring that different mahjong tiles have the same raising time, thereby achieving consistency in the overall shuffling time of different mahjong tiles.

[0108] Preferably, the stopping position is located near the card outlet 1142. Since the descending card lifting plate 220 is connected to the card outlet 1142, after the card lifting plate 220 descends, the movement of the card pushing component 130 can quickly push the mahjong tiles onto the card lifting plate 220, thereby speeding up the card playing speed.

[0109] like Figures 1 to 12As shown, the projections of the card lifting motor 210 and the card pushing motor 120 on the bottom plate 20 are all located outside the projection of the shuffling tray 30 on the bottom plate 20. In this way, the interference between the card lifting motor 210 and the card pushing motor 120 and the shuffling tray 30 is avoided, and the height of the automatic mahjong machine is also avoided from being increased due to the interference between the card lifting motor 210 and the card pushing motor 120 and the shuffling tray 30, so that the components inside the automatic mahjong machine can be more compact.

[0110] In one embodiment, the combination of Figure 1 、 Figure 3 、 Figure 6 、 Figures 9 to 12 is described for the phased card feeding method of the automatic mahjong machine. It should be noted that before the phased card feeding, a previous set of mahjong tiles in the automatic mahjong machine has been shuffled and arranged in the card pushing groove 114 in sequence, and along the pushing direction of the card pushing head 114, the card pushing groove 114 is arranged in sequence with the mahjong tiles required for the second card feeding stage, the card pushing head 114, and the mahjong tiles required for the first card feeding stage.

[0111] The phased card feeding stage includes the following steps:

[0112] After the automatic mahjong machine receives the first card feeding instruction, the card lifting plate 220 is lowered;

[0113] The card pushing mechanism 100 operates to push the preset mahjong tiles required for the first card feeding stage onto the card lifting plate 220, the first sensor 11 detects that the card pushing component 130 is located at the termination position, and the card pushing mechanism 100 stops moving;

[0114] The card lifting plate 220 is raised to lift the mahjong tiles of the first card feeding stage onto the tabletop of the automatic mahjong machine;

[0115] The card pushing mechanism 100 operates to move the card pushing head 131 to the starting position;

[0116] After receiving the second card feeding instruction, the card lifting plate 220 is lowered;

[0117] The card pushing mechanism 100 operates to push the preset mahjong tiles required for the second card feeding stage onto the card lifting plate 220, the first sensor 11 detects that the card pushing component 130 is located at the termination position, and the card pushing mechanism 100 stops moving;

[0118] The card lifting plate 220 is raised to lift the mahjong tiles of the second card feeding stage onto the tabletop of the automatic mahjong machine.

[0119] Among them, the first card feeding instruction is usually manually triggered, for example, triggered by the user through the keys on the control panel of the automatic mahjong machine.

[0120] The second tile placing instruction can be manually triggered, for example, triggered by a user through a button on a control panel of the automatic mahjong machine. The second tile placing instruction can also be automatically triggered, for example, triggered by a sensor after the sensor detects that all the mahjong tiles in the four groups of mahjong tile piles on the tile lifting plate 220 are taken away. The sensor can be an optical sensor or a gravity sensor arranged on the tile lifting plate 220. The sensor can also be another sensor arranged on the control panel or the tile lifting mechanism 200 of the automatic mahjong machine for detecting the action state and / or the bearing state of the tile lifting plate 220.

[0121] In some other embodiments, after the tile pushing mechanism 100 runs the tile pushing head 131 to the starting position, the tile pushing mechanism 100 continues to run to push the mahjong tiles required for the second tile placing stage in the tile pushing groove 114 towards the tile outlet 1142, and the third sensor 13 detects the mahjong tiles, and the tile pushing mechanism 100 stops running. After the second tile lifting stage starts, the tile lifting plate 220 is lowered, and the tile pushing mechanism 100 runs to push the mahjong tiles onto the tile lifting plate 220.

[0122] In some other embodiments, after the tile lifting plate 220 lifts the mahjong tiles in the first tile lifting stage to the table top of the automatic mahjong machine, the tile pushing mechanism 100 remains stationary, and the tile pushing head 131 stays in the termination position. After receiving the second tile placing instruction, the tile pushing mechanism 100 runs, and the tile pushing head 131 pushes the mahjong tiles in the second tile placing stage in the tile pushing groove 114 towards the tile outlet 1142. After the tile pushing head 131 passes through the starting position, the tile lifting plate 220 is lowered.

[0123] In one embodiment, the automatic mahjong machine is combined with Figure 1 、 Figure 3 、 Figures 10 to 12 The tile arranging method for the automatic mahjong machine is described.

[0124] It should be noted that the tile arranging method for the automatic mahjong machine is used to arrange the mahjong tiles in the tile pushing groove 114 and the tile pushing head 131 into an arrangement sequence that meets the tile arranging method.

[0125] The tile arranging method for the automatic mahjong machine includes the following steps:

[0126] The tile sucking device 50 and the tile stacking device 60 push the mahjong tiles in the form of piles into the tile pushing groove 114 according to the preset number of mahjong tiles required for the first tile placing stage;

[0127] At least one of the tile sucking device 50 and the tile stacking device 60 stops running to stop pushing the mahjong tiles into the tile pushing groove 114;

[0128] The pushing mechanism 100 pushes the mahjong tiles needed in the first mahjong pushing stage to the direction of the tile outlet 1142, and the third sensor 13 stops the pushing mechanism 100 after detecting the first mahjong tile, and the pushing head 131 stays behind the mahjong tiles needed in the first mahjong pushing stage in the pushing direction, meanwhile, the tile sucking device 50 and the tile stacking device 60 continue to send and stack the tiles;

[0129] The tile sucking device 50 and the tile stacking device 60 push the mahjong tiles needed in the second mahjong pushing stage into the pushing groove 114 according to the preset number of the mahjong tiles, and the mahjong tiles needed in the second mahjong pushing stage stay behind the pushing head 131 in the pushing direction; the tile sucking device 50 reverses to exit the sucked mahjong tiles;

[0130] After the four sets of tile sorting devices complete the tile sorting in the stage-by-stage tile pushing method, the control panel prompts that the tile sorting is completed.

[0131] After the tile sorting in the stage-by-stage tile pushing method is completed, the mahjong tiles needed in the first mahjong pushing stage, the pushing head 131 and the mahjong tiles needed in the second mahjong pushing stage are arranged in the pushing groove 114 from the tile outlet 1142 to the tile inlet 1141 in sequence. When the stage-by-stage tile pushing is performed, the pushing head 131 only needs to rotate in one direction along the pushing direction according to the stage-by-stage tile pushing method, so as to complete the stage-by-stage tile pushing.
