Description

TECHNICAL FIELD

[0001] The utility model relates to the field of automatic mahjong machine, especially to the automatic mahjong machine's stack push mechanism and stack push card device. BACKGROUND

[0002] The existing automatic mahjong machine completes the disorder and stacking of the mahjong machine through the card arranging device, and the card arranging device comprises a card feeding mechanism, a stack push mechanism and a flat push card device. The stack push mechanism is installed on the push lifting support of the flat push card device. The card feeding mechanism adsorbs the mahjong cards and transports them to the stack plate of the stack push mechanism, and the stack push mechanism pushes the stacked mahjong cards to the flat push card device.

[0003] For example, the Chinese utility model patent with the publication number CN201454056U and the name of mahjong table card arranging and stack push mechanism comprises a stack transmission part for driving the stack seat to lift and a push card slider for driving the push card plate to move horizontally. The card bearing cam is installed on the motor shaft of the stack motor, and the cam groove and the transmission pin are arranged on the card bearing cam. The cam groove and the stack transmission part cooperate to realize the lifting movement of the stack unit, and the transmission pin and the sliding groove of the push card slider cooperate to realize the horizontal movement of the push card unit.

[0004] However, the coaxial installation of the push card slider, the card bearing cam and the stack motor causes the superposition of the dimensions of the three in the axial direction, resulting in the increase of the size of the stack push mechanism in the axial direction of the stack motor. The extension of the increased size to the outside of the mahjong machine leads to the increase of the width of the tabletop of the mahjong machine, resulting in the increase of the cost. The extension of the increased size to the inside of the mahjong machine will interfere with the lifting plate of the push lifting mechanism, resulting in the need to open a gap on the lifting plate and the additional cost.

[0048] As Figures 1 to 7 The utility model discloses a push mechanism of automatic mahjong machine, for with the card feeding mechanism and the card pushing mechanism of automatic mahjong machine cooperation completes the card of mahjong card.The card feeding mechanism is sequentially transported to the push mechanism of automatic mahjong machine with the magnet adsorption mahjong card, and the push mechanism of automatic mahjong machine pushes the mahjong tile mound of stacking code to the card pushing mechanism, and the card pushing mechanism pushes the mahjong tile mound of stacking code to the table surface of automatic mahjong machine.The specific structure and working principle of card feeding mechanism, push structure and card pushing mechanism are familiar to those skilled in the art, and here is not repeated.

[0049] The push mechanism of the embodiment includes push box 100, push motor 200, card receiving unit 300 and card pushing unit 400, and push motor 200, card receiving unit 300 and card pushing unit 400 are installed on push box 100.Push box 100 includes push box body 110, front cover 120 and rear cover 130, and push box body 110 has a receiving space to accommodate push motor 200, card receiving unit 300 and card pushing unit 400.

[0050] The card receiving unit 300 includes a card receiving cam 310, a card receiving transmission member 320 and a card receiving seat 330, and the upper end of the card receiving seat 330 is provided with a card receiving plate 331.The push motor 200 is drivingly connected to the card receiving cam 310, and the rotating movement of the card receiving cam 310 drives the card receiving seat 330 to move up and down through the card receiving transmission member 320, and the up-and-down movement of the card receiving seat 330 makes the card receiving plate 331 move up and down.The card pushing unit 400 includes a card pushing plate 410 and a card pushing slider 420, and the horizontal movement of the card pushing slider 420 drives the card pushing plate 410 to move horizontally.The card receiving cam 310 and the card pushing slider 420 are located on the radial side of the push motor 200, and at least part of the card pushing slider 420 is located in the axial length range of the push motor 200.The card receiving cam 310 is rotatably connected to the push box 100, one end of the card receiving transmission member 320 is rotatably connected to the push box 100, and the other end is connected to the card receiving seat 330.

[0051] Reference Figure 3The axial length range of the shuffling motor 200 refers to the axial distance between the two ends of the shuffling motor 200 farthest apart in the axial projection of the shuffling motor 200. The axial length range of the shuffling motor 200 includes the axial length of the motor housing 210 and the axial length of the motor shaft 220. The at least partial pusher slider 420 being located in the axial length range of the shuffling motor 200 refers to, in the axial direction of the shuffling motor 200, at least one end of the axial projection of the pusher slider 420 not exceeding the axial length range of the shuffling motor 200.

[0052] In combination Figure 2 , Figure 3 The shuffling motor 200 is located on the right side of the shuffling box 100, and the pusher slider 420 is always located on the left side of the shuffling motor 200 when moving horizontally.

[0053] In the shuffling mechanism of the embodiment, the pusher slider 420 is located on the radial side of the shuffling motor 200, and the at least partial pusher slider 420 is located in the axial length range of the shuffling motor 200, so that the lengths of the pusher slider 420, the shuffling motor 200, and the shuffling motor 200 in the axial direction of the shuffling motor 200 overlap, and this overlap reduces the lengths of the pusher slider 420, the shuffling motor 200, and the shuffling motor 200 stacked in the axial direction, so that the size of the shuffling mechanism in the axial direction of the shuffling motor 200 can be reduced.

[0054] In one embodiment, based on the shuffling mechanism of the foregoing embodiment, as shown in Figures 1 to 4 , the push direction is parallel to the length direction of the shuffling box 100, and the axial direction of the shuffling motor 200 is parallel to the width direction of the shuffling box 100. In this way, the space occupied by the pusher unit 400 and the shuffling motor 200 in the shuffling box 100 can be saved, so that the size of the outer contour of the shuffling box 100 can be further reduced.

[0055] In one embodiment, based on the shuffling mechanism of the foregoing embodiment, as shown in Figures 1 to 3 , the at least partial pusher slider 420 is located in the axial length range of the shuffling motor 200.

[0056] Since the at least partial pusher slider 420 is also located in the axial length range of the shuffling motor 200, the lengths of the pusher slider 420, the shuffling motor 200, and the shuffling motor 200 in the axial direction of the shuffling motor 200 overlap, and this overlap reduces the lengths of the pusher slider 420, the shuffling motor 200, and the shuffling motor 200 stacked in the axial direction, so that the size of the shuffling mechanism in the axial direction of the shuffling motor 200 can be further reduced.

[0057] In one embodiment, based on the stacking mechanism of the foregoing embodiments, such as Figures 1 to 3 As shown, the bearing drive component 320 is located on the radial side of the stacking motor 200, and at least a portion of the bearing drive component 320 has a length in the axial direction of the stacking motor 200 that is within the axial length range of the stacking motor 200.

[0058] In this way, the lengths of the pusher slider 420, the bearing cam 310, the bearing transmission component 320, and the stacking motor 200 overlap in the axial direction of the stacking motor 200. This overlap reduces the length of the pusher slider 420, the bearing cam 310, the bearing transmission component 320, and the stacking motor 200 in the axial direction, allowing the axial dimensions of the stacking mechanism of the stacking motor 200 to be further reduced.

[0059] In one embodiment, based on the stacking mechanism of the foregoing embodiments, such as Figures 1 to 3 As shown, the card-bearing cam 310 and the card-pushing slider 420 are located on the same radial side of the stacking motor 200.

[0060] Combination Figure 2 , Figure 3 The stacking motor 200 is located on the right side of the stacking box 100, the card-bearing cam 310 is located on the left side of the stacking box 100, and the card-pushing slider 420 is always located on the left side of the stacking motor 200 when it moves horizontally.

[0061] By placing the card-bearing cam 310 and the card-pushing slider 420 on the same radial side of the stacking motor 200, the dispersed arrangement of components in the stacking mechanism is avoided, making the internal structure of the stacking mechanism more compact and helping to reduce the outer dimensions of the stacking mechanism.

[0062] In one embodiment, based on the stacking mechanism of the foregoing embodiments, such as Figure 1 , Figure 4 , Figure 7 As shown, the stacking box 100 has a motor compartment 111, and the stacking motor 200 is at least partially housed in the motor compartment 111.

[0063] In this embodiment, the stacking box body 110 is provided with a motor compartment 111 for housing the stacking motor 200. The stacking motor 200 is at least partially housed in the motor compartment 111 and fixedly connected to the stacking box body 110. The stacking motor 200 is inserted into the motor compartment 111 from the rear side of the stacking box body 110, and a rear cover 130 is closed on the rear side of the stacking box body 110. The rear cover 130 is provided with an opening 131 for positioning the tail of the stacking motor 200, and the tail of the stacking motor 200 extends out from the opening 131.

[0064] In this way, the stacker motor 200 can be accommodated in the stacker box 100, and the axial length of the stacker motor 200 does not affect the size of the stacker box 100 in the axial direction of the stacker motor 200, thereby reducing the overall size of the stacker box 100.

[0065] In one embodiment, the stacker mechanism is based on the foregoing embodiments, as shown in Figures 1 to 7 The rotation of the card supporting cam 310 drives the horizontal movement of the card pushing slider 420 and the card pushing plate 331.

[0066] Specifically, the transmission member is arranged between the card supporting cam 310 and the card pushing slider 420, and the card supporting cam 310 is connected to the card pushing slider 420 through the transmission member, so that the rotation of the card supporting cam 310 can drive the movement of the card pushing slider and the card pushing plate.

[0067] The card pushing slider 420 is provided with a horizontally extending guide hole 422 in the pushing direction, and the stacker box 100 is provided with a guide rod which is slidingly fitted in the guide hole 422, so that the card pushing slider 420 can slide relative to the stacker box 100 in the horizontal direction. The card pushing plate 410 includes a connecting plate 411, and the card pushing plate 410 is connected to the card pushing slider 420 through the connecting plate 411, so that the card pushing plate 410 slides horizontally together with the card pushing slider 420.

[0068] In this way, the card pushing unit 400 is driven by the stacker motor 200 and the card supporting cam 310 to move, without the need for another set of driving mechanism, thereby reducing the number of parts of the stacker mechanism, making the internal structure of the stacker mechanism more compact, and further reducing the overall size of the stacker mechanism.

[0069] In one embodiment, the stacker mechanism is based on the foregoing embodiments, as shown in Figures 1 to 7 The card supporting cam 310 includes axially opposite first and second sides, the first side forms a first pair of movements with the card supporting transmission member 320, and the second side forms a second pair of movements with the card pushing slider 420.

[0070] In this way, the first pair of movements and the second pair of movements are avoided from interfering with each other, simplifying the design of the stacker mechanism and making the internal structure of the stacker mechanism more compact.

[0071] In one embodiment, the stacker mechanism is based on the foregoing embodiments, as shown in Figures 1 to 7As shown, the first kinematic pair and the second kinematic pair are described, the first kinematic pair includes a card receiving curved groove 311 provided on the first side and presenting a closed cam curve track, and a card receiving guide block provided on the card receiving driving member 320, the card receiving guide block reciprocatingly slides in the card receiving curved groove 311. The second kinematic pair includes a card pushing guide block 314 provided on the second side and a card pushing curved groove 421 provided on the card pushing sliding block 420, the card pushing guide block 314 reciprocatingly slides in the card pushing curved groove 421.

[0072] In the embodiment, the central concave of the card receiving cam 310 forms the card receiving curved groove 311, the card receiving curved groove 311 includes a cam outer wall 312 provided outside the card receiving guide block and a cam inner wall 313 provided inside the card receiving guide block, the cam outer wall 312 and the cam inner wall 313 enclose the closed cam curve track of the card receiving curved groove 311. The cam curve track is configured to have a track with three different states, the three different states of the track make the straight line distance between the card receiving guide block located in the cam curve track and the rotation axis of the card receiving cam 310 have three states of gradually increasing, gradually decreasing and keeping unchanged. Since one end of the card receiving driving member 320 is rotationally connected with the stacking and pushing box 100, the card receiving driving member 320 can only swing around the rotation connection point, and the card receiving guide block can only move up and down under the action of the card receiving curved groove 311, so that the movement of the card receiving driving member 320 driving the lifting movement of the card receiving plate 331 has three states of rising, falling and keeping still.

[0073] In the embodiment, the card pushing curved groove 421 extends along the longitudinal direction and has a connected straight groove segment 4211 and a curved groove segment 4212. The rotation of the card receiving cam 310 drives the rotation of the card pushing guide block 314, and the action of the card pushing guide block 314 on the groove wall of the card pushing curved groove 421 makes the card pushing sliding block 420 reciprocate in the card pushing direction. The curved groove segment 4212 has a track matched with a certain segment of the movement path of the card pushing guide block 314, when the card pushing guide block 314 slides in the curved groove segment 4212 without force on the groove wall of the card pushing curved groove 421, the card pushing sliding block 420 keeps still in this stage, so that the movement of the card pushing plate 410 has three states of pushing, resetting and keeping still, and the card receiving plate 331 and the card pushing plate 410 can be alternately moved to realize the stacking and pushing of the mahjong tile stack.

[0074] Through the above setting, the simple structure realizes the stacking and pushing of the mahjong tile stack, simplifies the design difficulty of the stacking and pushing mechanism, and reduces the cost of the stacking and pushing mechanism.

[0075] In one embodiment, based on the stacking and pushing mechanism of the foregoing embodiment, like Figures 1 to 3As shown, the stacking motor 200 and the bearing cam 310 are connected through the gear set 500, so that the transmission precision between the stacking motor 200 and the bearing cam 310 can be improved, thereby improving the operation accuracy and stability of the bearing unit 300.

[0076] In one embodiment, based on the stacking mechanism of the foregoing embodiment, as shown in Figures 1 to 3 As shown, the gear set 500 includes a driving gear 510, a driven gear 530, and a transmission gear 520 connected between the driving gear 510 and the driven gear 530, the driving gear 510 is connected to the motor shaft 220 of the stacking motor 200 so as to rotate coaxially with the motor shaft 220 of the stacking motor 200, the driven gear 530 is connected to the bearing cam 310 so as to rotate coaxially with the bearing cam 310, and the driven gear 530, the transmission gear 520, and the driving gear 510 are sequentially engaged in the direction of pushing the card.

[0077] In this embodiment, the transmission gear 520 is provided with one, and the transmission gear 520 is rotatably connected to the stacking box 100.

[0078] In this embodiment, the transmission gear 520 is provided with one, and the transmission gear 520 is rotatably connected to the stacking box 100.

[0079] It can be understood that in other embodiments, the transmission gear 520 can also be provided with a plurality of, and the driven gear 530, the plurality of transmission gears 520, and the driving gear 510 are sequentially engaged in the direction of pushing the card.

[0080] By providing the driving gear 510, the driven gear 530, and the transmission gear 520 connected between the driving gear 510 and the driven gear 530, on the one hand, the precise transmission between the stacking motor 200 and the bearing cam 310 is achieved, and on the other hand, the transmission gear 520 can reduce the outer diameter of the driving gear 510 and the driven gear 530, avoid the interference between the driving gear 510, the driven gear 530, and the stacking box 100 in the axial direction, and the reduction of the driving gear 510 and the driven gear 530 can also save materials and reduce costs.

[0081] In one embodiment, based on the stacking mechanism of the foregoing embodiment, as shown in Figures 1 to 3 As shown, the driven gear 530 is integrally formed on the outer periphery of the bearing cam 310.

[0082] Specifically, the outer periphery of the bearing cam 310 is integrally formed with a plurality of tooth portions, and the plurality of tooth portions constitute the gear teeth of the driven gear 530, so that the driven gear 530 is integrally formed on the outer periphery of the bearing cam 310.

[0083] In this way, the bearing cam 310 can directly engage the transmission gear 520, thereby reducing the number of parts in the stacking mechanism and reducing the material and installation costs of the stacking mechanism.

[0084] The license plate cam 310 can be made of plastic material by injection molding, can be made of metal material by powder metallurgy, or can be made of plastic or metal material by machining.

[0085] In one embodiment, based on the foregoing embodiment, the push-stacking mechanism is as shown in Figure 1 , Figure 3 The push-stacking motor 200 further includes a motor body mounted in the motor housing 210, and a motor shaft 220 rotatably mounted on the motor housing 210 and extending out of an end face of the motor housing 210. The motor body has a drive shaft on which a driving unit is mounted, and the motor shaft 220 has a transmission unit at an end close to the drive shaft. The driving unit drives the transmission unit so that the rotation of the drive shaft drives the rotation of the motor shaft 220. The drive shaft is coaxially arranged with the motor housing 210, the motor shaft 220 is parallel to the drive shaft, and the motor shaft 220 deviates from the center of the end face of the motor housing 210 towards the license plate cam 310.

[0086] The driving unit and the transmission unit can be gears. Alternatively, the driving unit can be a gear portion extending axially on the drive shaft.

[0087] Through the above arrangement, the distance between the motor shaft 220 and the license plate cam 310 is shortened, and accordingly, the size of the transmission structure between the push-stacking motor 200 and the license plate cam 310 and the amount of material used can also be reduced, thereby reducing the cost of the push-stacking mechanism. At the same time, the reduction of the transmission structure also makes the internal structure of the push-stacking mechanism more compact.

[0088] The utility model discloses still propose automatic mahjong machine's push-stacking and putting device, as shown in Figure 8 , Figure 9 The push-stacking and putting device includes a push and putting mechanism 600 and any one of the push-stacking mechanisms in the foregoing embodiments, and the push-stacking mechanism is connected to one end of the push and putting mechanism 600 in the axial direction.

[0089] In this way, the push-stacking mechanism and the push and putting mechanism 600 together constitute a push-stacking and putting device that extends in the axial direction of the push and putting mechanism 600, thereby reducing or avoiding the increase in the width of the push-stacking and putting device due to the size of the push-stacking mechanism and the push and putting mechanism 600 in the width direction, and thus making the push-stacking and putting device thinner.

[0090] In one embodiment, based on the foregoing embodiment, the push-stacking and putting device is as shown in Figure 8 , Figure 9 The push and putting mechanism 600 includes a tile lifting plate 610 that moves up and down, the push-stacking box 100 includes a first side and a second side opposite in the width direction, the first side avoids the up and down movement of the tile lifting plate 610, and the tail of the push-stacking motor 200 is located on the second side.

[0091] The mahjong machine is usually provided with four sets of stacking and feeding devices, and the flat pushing and feeding mechanism 600 is provided with four groups and is arranged around the center of the mahjong machine, and the lifting plate 610 is arranged at the inner side of the flat pushing and feeding mechanism 600, and the first side of the stacking and pushing box 100 avoids the lifting movement of the lifting plate 610, so that the first side of the stacking and pushing box 100 in the thickness direction is substantially flush with the inner side of the flat pushing and feeding mechanism 600, thereby avoiding the interference between the stacking and pushing box 100 and the lifting movement of the lifting plate 610.

[0092] By avoiding the lifting movement of the lifting plate 610 at the first side of the stacking and pushing box 100 in the width direction and locating the tail of the stacking motor 200 at the second side, the lifting plate 610 does not need to be provided with a notch for avoiding the stacking and pushing box 100 or the stacking motor 200, thereby simplifying the design of the lifting plate 610.

[0093] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this, and those skilled in the art should understand that the present application includes but is not limited to the contents described in the drawings and the above specific embodiment. Any modification without deviating from the function and structural principle of the present application will be included in the scope of the claims.
