Description

Technical Field

[0001] The invention belongs to the field of mahjong machine manufacturing, and in particular relates to a mahjong machine and a horizontal push card loading device and a card loading method thereof. Background Art

[0002] Mahjong is widely loved by the people as a leisure and entertainment tool, and is listed as a sports competition. The square mahjong tiles of traditional mahjong machines are parallel to the edges of the table after they are raised to the table, and the mahjong tiles are very close to the edge of the table, and the position is unreasonable. Before drawing the tiles, the players need to manually move the mahjong tiles forward and place them diagonally to the appropriate position. In the process of moving the mahjong tiles, the mahjong tiles are easy to fall over, which brings inconvenience to the players.

[0003] Patent documents such as publication number CN200966910 disclose a mahjong machine with a ramped card loading method, which has a table top with a card loading port in the center, four rectangular windmill-shaped card output ports arranged on the table top and inclined at an angle to the edge of the table top, four arc-shaped card storage slots arranged in a windmill shape below the table top, a card delivery pusher is installed at the end of each card storage slot, and a card lifting board is provided on each card output port, one end of the card lifting board is hinged with the card output port, and the other end is movably connected with a card lifting mechanism, and the four card output ports are arranged in a windmill shape. When loading cards, a part of the mahjong tiles first arrive on the table top along the card lifting board, and the remaining part of the mahjong tiles are located on the card lifting board, and finally the card lifting mechanism lifts the mahjong tiles on the card lifting board to the table top. Although this roller coaster-style mahjong machine can tilt the four-square wall of mahjong tiles in a windmill shape after the tiles reach the table, the loading speed is slow, and the tiles placed along the slope are prone to gaps, confusion, or even overturning after they rise to the table. Generally, players are still required to manually sort the tiles, and the inconvenience caused to players has not been completely solved.

[0004] Patent documents such as publication number CN109381855A disclose a mahjong machine, in which the mahjong tiles on the four sides of the mahjong machine are lifted onto the mahjong table top at once in the form of being tilted to the four sides of the mahjong table top and close to the center of the mahjong table top. However, the layout of the conveying mechanism, stacking and pushing mechanism and card loading mechanism on the four sides of the mahjong machine is not reasonable enough, resulting in only one lifting board bracket being arranged at the bottom of each lifting board. In order to ensure that the lifting board can be lifted and lowered, the lifting boards of every two adjacent lifting boards of the loading mechanism are connected by a fixing plate, and the four lifting boards on the four sides must be lifted and lowered synchronously. Because the four lifting boards are connected as one, the volume is large, and the lifting boards are driven by four loading motors separately, which makes it difficult to lift and lower synchronously, so the action stability of the loading mechanism is poor and it is easy to get stuck and damaged. And also due to the layout restrictions, the height difference between the card outlet height of the conveying mechanism and the descending height of the card lifting plate is large, the lifting span of the card receiving seat in the stacking and pushing mechanism is too large (greater than the thickness of two mahjong tiles), the stacking and pushing efficiency is low, the operation is unstable, and the mahjong cards are easily confused.

[0005] Patent documents such as publication number CN112023390A disclose a mahjong machine, comprising a shuffling plate located in the center of a bottom plate of a frame, four sets of card picking and transporting systems are arranged around the shuffling plate, the card picking and transporting system comprises a card feeding device, a horizontal push card loading device and a card pushing device; the horizontal push card loading device comprises a card bearing plate, a card supporting plate and a card pushing plate, the card supporting plate is located on the inner side of the card bearing plate, the card pushing plate is located on the outer side of the card bearing plate and pushes the cards from the outside to the inside, one end of the card bearing plate extending along the length direction is a card inlet, a card bearing block of the card pushing device is arranged outside the card inlet, and a horizontal push card loading motor drives the card pushing plate to translate and push the cards and the card supporting plate to lift and load the cards; four card loading ports which are respectively arranged obliquely relative to the side edges of the desktop panel are arranged on the panel of the mahjong machine, and the four card supporting plates in the four sets of card picking and transporting systems are respectively matched with the four card loading ports. This scheme adopts four-way independent horizontal push card loading, and fully utilizes the space at the corner connection of the two card feeding devices to set up the card loading support frame and its card loading crank, so that the lifting and lowering of the card supporting plates of the four-way horizontal push card loading devices are driven by their own motors to load cards independently.

[0006] However, in the above-mentioned flat push card windmill-shaped mahjong machines disclosed in the patent documents such as CN109381855A and CN112023390A, the square card wall tilted in the shape of a windmill is placed further outward than the square card wall of the slope card windmill-shaped mahjong machine. Generally, the player still needs to manually push the mahjong card wall a little bit to be suitable for the player to play cards, which still causes inconvenience to the player. In addition, in the structure of this type of mahjong machine, the card-discharging direction of the card-feeding device and the card-feeding direction of the flat push card-feeding device are not perpendicular, but are at an acute angle. The mahjong cards from the card-feeding device need to be rotated at a certain angle before they can be pushed into the card storage slot (on the card-bearing plate) of the flat push card-bearing device, and the card-pushing head in the card-pushing device implements a straight-line movement to push cards along the card-feeding direction (the length direction of the card-bearing plate) of the flat push card-bearing device, which easily leads to poor card pushing or card jamming. Summary of the invention

[0007] In order to solve the above technical problems of the prior art, the purpose of the present invention is to provide a mahjong machine and a flat-push card loading device and card loading method thereof, which push the four-sided mahjong wall inward so that players do not need to push the cards inward when playing cards;

[0079] Embodiment 1:

[0080] In the present invention, for the convenience of description, the center of the mahjong machine is referred to as the "inside" and the surroundings of the mahjong machine are referred to as the "outside".

[0081] like Figures 1 to 4 A mahjong machine shown in the figure includes a shuffling plate 2, a card scraper and a central lifting device located in the center of a frame bottom plate 1. Four sets of card picking and transporting systems are arranged around the shuffling plate 2. The card picking and transporting systems include a card feeding device 5 for picking up mahjong tiles one by one from the shuffling plate and delivering them, a horizontal push card loading device 7 for delivering multiple piles of arranged mahjong tiles onto the mahjong machine table at one time, and a card pushing device 6 for pushing the mahjong tiles delivered by the card feeding device 5 into the horizontal push card loading device 7.

[0082] The card feeding device 5 generally includes a card feeding shell, in which a card feeding channel for transferring mahjong cards is provided, a card suction wheel is provided at the card inlet of the card feeding channel, a conveyor belt driven by a card feeding motor is provided in the card feeding channel, and the card pushing device 6 is provided outside the card outlet of the card feeding channel; two adjacent card feeding devices 5 are transitionally connected by a connecting wall, and the four card feeding devices 5 in the four groups of card picking and transporting systems are respectively connected end to end by four connecting walls to form a card feeding frame, which is arranged around the shuffling plate 2, the card inlet of the card feeding device 5 is located on the inner wall of the card feeding frame, and the card outlet of the card feeding device 5 is located on the outer side of the card feeding frame.

[0083] In this embodiment, the card delivery channel can be a traditional straight channel or an arc-shaped card delivery channel. In order to ensure the reliability of mahjong card delivery, it is preferred that the card delivery channel has a card outlet height not lower than the card inlet height of the card delivery channel. The specific structure of the card delivery device is prior art, and reference can be made to patent documents such as publication numbers CN213965119U, CN105363195A, CN105413161A, CN106492454A, CN106669142A, and CN112023390A.

[0084] The card pushing device 6 includes a card receiving block 61 for receiving the mahjong tiles sent by the card sending device 5 and a card pushing head 62 for pushing the mahjong tiles on the card receiving block 61 to the horizontal card pushing device 7. The card receiving block 61 and the card pushing head 62 are driven by a card pushing motor 68. The specific structure of the card pushing device can adopt the existing technology, and reference can be made to patent documents such as publication numbers CN201906453U, CN201949619U, CN103861280A, CN112023390A and CN204699375U. However, the card pushing heads of the card pushing devices in the prior art all push cards by moving in a straight line, while in the flat-push card-loading windmill-shaped mahjong machine structure, the card-discharging direction of the card-feeding device and the card-feeding direction of the flat-push card-loading device are not perpendicular, but are at an acute angle. The mahjong tiles coming out of the card-feeding device need to be rotated at a certain angle before they can be pushed into the card storage slot (on the card-receiving plate) of the flat-push card-loading device. In this way, the card pushing head in the card pushing device pushes cards by moving in a straight line along the card-feeding direction (the length direction of the card-receiving plate) of the flat-push card-loading device, which can easily lead to poor card pushing or card jamming.

[0085] Therefore, in this embodiment, the card pushing device preferably adopts a swinging card pushing head. Figure 5 and Figure 6 The card pushing device shown includes a card pushing housing, a card pushing motor 68 is installed on the card pushing housing, a card pushing transmission mechanism is arranged inside the card pushing housing, a card receiving block 61 and a card pushing head 62 are arranged outside the card pushing housing, the card pushing motor 68 drives the card receiving block 61 to rise and fall through the card pushing transmission mechanism to realize the stacking of mahjong tiles, and the card pushing motor 68 drives the card pushing head 62 to swing back and forth horizontally around a specific axis through the card pushing transmission mechanism to push the stacked mahjong tiles out of the card receiving block 61, and the specific axis is vertically arranged outside the card receiving block 61 and arranged along the card discharging direction of the card feeding device 5. In this way, the swinging card pushing head is more suitable for the layout of the card feeding device and the flat push card loading device of the flat push card loading windmill-shaped mahjong machine, and the card pushing is smooth and stable without card jamming.

[0086] Further preferably, the card pushing head 62 has at least two card pushing parts: when the card pushing head 62 starts to push the mahjong tiles on the card receiving block 61, the first card pushing part first contacts the mahjong tiles; when the card pushing head 62 pushes the mahjong tiles onto the card receiving plate 72, the second card pushing part contacts the mahjong tiles, or the first card pushing part and the second card pushing part contact the mahjong tiles at the same time. The card pushing part here can be a card pushing part that forms surface contact or line contact with the upper and lower mahjong tiles. In this embodiment, the first card pushing part is a card pushing part that forms line contact with the upper and lower mahjong tiles. For example, the card pushing surface of the card pushing head 62 includes two planes, a first plane and a second plane, and the two planes are at different distances from the specific axis: when the card pushing head 62 starts to push the mahjong tiles on the card receiving block 61, the connection of the two planes or the first plane first contacts the mahjong tiles; when the card pushing head 62 pushes the mahjong tiles onto the card receiving plate 72, the second plane contacts the mahjong tiles. In this way, not only can the mahjong tiles be turned first so that the mahjong tiles can be pushed into the card storage slot (formed by the card support plate and its inner and outer side retaining walls) of the flat push card loading device more smoothly, but also the direct surface contact and collision between the card pusher and the mahjong tiles to generate loud noise can be avoided, and the noise or card jamming caused by the collision between the mahjong tiles and the retaining wall at the entrance of the card storage slot can be avoided.

When the card bearing plate 72 rises upward, its height is higher than the inner side retaining wall, so that the mahjong tiles on the card bearing plate 72 can be prevented from falling chaotically. In this embodiment, the card loading transmission mechanism uses a horizontal push card loading motor 76 to drive the card supporting plate 71, the card bearing plate 72 and the card pushing plate 73 to achieve card lifting, card pushing and card loading.

[0121] In other embodiments, the flat-pushing card-loading device 7 having the above-mentioned liftable card-receiving plate 72 can also be combined with the card-pushing device 6 for pushing a single mahjong tile, so that the card-receiving plate 72 has at least three stop positions: in the first stop position, the card-receiving plate 72 receives the single mahjong tile pushed by the card-pushing device 6 and arranges it to form a first layer of mahjong tiles; in the second stop position, the card-receiving plate 72 receives the single mahjong tile pushed by the card-pushing device 6 and arranges it to form a second layer of mahjong tiles; in the third stop position, the card-pushing plate 73 pushes the multiple piles of mahjong tiles arranged on the card-receiving plate 72 onto the card-supporting plate 71.

[0122] In other embodiments, the flat-push card-loading device 7 having the above-mentioned liftable card-holding plate 72 can also adopt staged card loading. For example, three layers of mahjong tiles are stored on the card-holding plate 72. When loading the tiles, the card-supporting plate 71 descends to the bottom, and the card-pushing plate 73 first pushes the top layer of mahjong tiles onto the card-supporting plate 71, and the card-supporting plate 71 rises upward to deliver the mahjong tiles to the table. After the player takes the mahjong tiles away, the card-supporting plate 71 descends again, and the card-pushing plate 73 pushes the remaining two layers of mahjong tiles onto the card-supporting plate 71, and the card-supporting plate 71 rises upward to deliver the mahjong tiles to the table.

[0123] In the prior art, the flat push-on windmill-shaped mahjong machines disclosed in patent documents such as publication numbers CN209645828U, CN109381855A, and CN112023390A have a square wall of tiles placed in a windmill shape that is tilted further outward than the square wall of the windmill-shaped mahjong machine with a sloped tile. Generally, players still need to manually push the mahjong tile wall a little further in order to make it suitable for the players to play, which still causes inconvenience to the players. Therefore, it is preferred to push the mahjong tile wall inward to a position similar to that of the windmill-shaped mahjong machine with a sloped tile, so that the players do not need to push the tiles again.

[0124] One implementation scheme is that the card support plate 71 and its driving mechanism adopt the existing technical structure, the card support plate 71 extends inwardly and widens, and the width of the card support plate 71 is greater than the width of the mahjong wall, that is, the card support plate 71 forms a supporting area for placing the mahjong wall and a transition area located outside the supporting area where the mahjong wall is not placed, and the transition area is only connected to the card support plate 72 when the card pushing plate 73 pushes the cards and allows the mahjong wall to pass through. However, there are several problems with such a structure: first, the wide card loading opening and the card support plate are set on the desktop board, which affects the beauty of the mahjong machine. Secondly, the four wide card loading openings will cause the desktop board to have a large hollow area, low strength and easy deformation. Then, in order to prevent the lifting assembly (including the guide rod, the card loading crank and the card loading cam, etc.) at the bottom of the card support plate 71 from occupying too much shuffling space, the lifting assembly generally supports the card support plate 71 outside the mahjong wall, which will cause the support of the card support plate to be unbalanced and not stable enough, and easily cause the card support plate to loosen, affecting the service life of the mahjong machine. Of course, the latter two problems can be solved by improving materials, adding reinforcing members or strengthening structures. Therefore, this embodiment can be used in occasions where the aesthetic requirements of the mahjong machine are not high.

[0125] Another embodiment is that the width of the card support plate 71 remains unchanged, the position of the card support plate 71 is moved inward, and when the card support plate 71 drops to the bottom, a transition plate 74 is provided between the card support plate 71 and the card receiving plate 72, so as to connect the card receiving plate 72 and the card support plate 71 when the card pushing plate 73 pushes the cards and allow the mahjong card wall to pass through. The transition plate 74 is installed on the card support plate 71, the card receiving plate 72 or the upper card seat 70. The transition plate 74 can be fixed or integrally formed on the card receiving plate 72 or the upper card seat 70.

[0126] This embodiment is preferred, as Fig.24 , Fig.25 , Fig.34 , Fig.37 , Fig.40 , Fig.43 , Fig.47 and Fig.48 As shown, the transition plate 74 is hinged to the inner side of the card bearing plate 72 or the card holder 70 so that the transition plate 74 can be erected or laid flat. Fig.25As shown, the transition plate 74 is in an upright state so as to serve as an inner retaining wall of the card-bearing plate 72 to prevent the mahjong tiles from falling off the card-bearing plate 72; when the card-pushing device 7 pushes the tiles, as shown in FIG. Fig.26 and Fig. 27 As shown, the card supporting plate 71 is lowered, the transition plate 74 is laid flat, and the card pushing plate 73 pushes the mahjong card wall inward; Fig.28 and Fig.29 As shown, the transition plate 74 is in a flat state to form a transition area through which the mahjong wall can be pushed; Fig.30 and Fig.31 As shown, the push plate 73 pushes the mahjong wall onto the supporting plate 71 and then resets, and the transition plate 74 stands up and resets; Fig.32 and Fig.33 As shown, the card support plate 71 raises the mahjong card wall onto the mahjong tabletop. The structure is simple, the installation is convenient, and the function is reliable.

[0127] It is further preferred that the transition plate 74 is given an upward tendency by an elastic member. In this way, the transition plate is in an upright state when not subject to external force, and is pressed and laid flat by pushing cards, which can not only avoid interference between the transition plate 74 and the card support plate 71, but also eliminate the need to set additional supporting members to support the transition plate. The elastic member can be a tension spring, a torsion spring or an elastic push rod, etc., but is preferably a torsion spring sleeved on the hinge shaft of the transition plate 74.

[0128] In this embodiment, the transition plate 74 is preferably provided with a tendency to lie flat by an elastic member. In this way, the transition plate is in a flat state when not subjected to external force, which reduces the load of the motor pushing the cards and the collision noise of the pushing cards, but an additional support structure or support member is required to support the transition plate. The elastic member may be a tension spring, a torsion spring or an elastic push rod, etc., but is preferably a torsion spring sleeved on the hinge shaft of the transition plate 74.

[0129] It is further preferred that a first transition support 711 is provided on the outer side of the card support plate 71. The first transition support 711 is horizontally arranged and lower than the top surface of the card support plate 71 so as to form a step with the card support plate 71. When the card support plate 71 is lowered to the bottom transition plate 74 and laid flat, the first transition support 711 supports the transition plate 74. When the card support plate 71 is raised to the top, the first transition support 711 can form a support with the desktop board 4. In this way, the first transition support 711 can not only support the transition plate 74, but also form a support with the bottom of the desktop board 4 to improve the stability of the card support plate, avoid looseness affecting the service life, and have a simple and reliable structure with low cost. The first transition support 711 can be a whole plate, or it can be composed of a plurality of small support plates, it can be an independent component fixedly connected to the card support plate 71, or it can be integrally formed with the card support plate 71. In this embodiment, it is preferred that the first transition support 711 is a whole plate integrally formed with the card support plate 71, and the support is more firm and reliable. More preferably, the lifting guide component (guide rod or guide sleeve) of the card supporting plate 71 is arranged on the first transition support 711, and the card loading cam 713 of the card supporting plate 71 is arranged at the bottom of the card supporting plate 71. This can more evenly and stably support the card supporting plate 71 and the mahjong card wall thereon, further prevent the card supporting plate 71 from loosening and increase its service life.

[0130] It is further preferred that a second transition support 712 is provided on the outer side of the first transition support 711, and the second transition support 712 is vertically arranged and fixedly connected or integrally formed with the first transition support 711; when the transition plate 74 is erected and the card support plate 71 is raised, the second transition support 712 forms an inner limit for the transition plate 74. This can not only form a reliable limit block for the transition plate 74, but also prevent the transition plate 74 from turning inwards and interfering with the lifting and lowering of the card support plate 71. The first transition support 711 can be a whole plate, but is preferably composed of at least two small support plates.

[0131] In other embodiments, the transition plate 74 may also be movably disposed at the bottom of the card supporting plate 71 .

[0132] In other embodiments, Fig.47 and Fig.48 As shown, on the push-pull card loading device 7 in which the card bearing plate 72 can be raised and lowered, the transition plate 74 can also be movably arranged on the top of the inner baffle wall of the card bearing plate 72, and the inner baffle wall is integrally formed with or fixedly connected to the card loading seat 70.

[0133] The mahjong tile arrangement method using the mahjong machine and the card picking and transporting system of the present embodiment comprises the following steps:

[0134] 1) Card delivery; the card delivery device 5 picks up the mahjong tiles 100 from the shuffling plate 2 and delivers it to the card pushing device 6;

[0135] 2) stacking and pushing cards; the card receiving block 61 of the card pushing device 6 receives a mahjong tile sent by the card sending device 5 at the first stop position; the card receiving block 61 descends to the second stop position to receive another mahjong tile sent by the card sending device 5; the card receiving block 61 rises to the third position and the card pushing head 62 pushes the two mahjong tiles stacked into one pile onto the card receiving plate 72 of the flat push card loading device 7, and then the card receiving block 61 and the card pushing head 62 are reset;

[0136] 3) Repeat the above step 2) until the required number of mahjong tiles (mahjong tile wall) is arranged on the tile support plate 72 of the horizontal push-on device 7;

[0137] 4) Pushing the cards horizontally; after receiving the card loading instruction, the card supporting plate 71 of the horizontal pushing card loading device 7 drops from the desktop to a low position, and the card pushing plate 73 pushes the multiple piles of mahjong tiles (mahjong tile wall) on the card bearing plate 72 onto the card supporting plate 71 via the transition plate 74; the card supporting plate 71 rises to the desktop.

[0138] In a preferred embodiment, in the above step 2), the first stop position and the third stop position of the card receiving block 61 of the card pushing device 6 are at the same height. In other embodiments, the card receiving block 61 of the card pushing device 6 is lower than the third stop position at the first stop position.
