Description

Technical Field

[0001] The invention relates to the field of mahjong machines, in particular to an eight-mouth automatic mahjong machine and a mahjong loading component thereof. Background Art

[0002] The current fully automatic mahjong machines can integrate functions such as shuffling cards and rolling dice, providing a lot of convenience for people to play cards.

[0003] For example, a Chinese patent document with publication number CN105413165B discloses an automatic mahjong machine, comprising a card feeding device, a card pushing device, and a ramp card discharging device, wherein the ramp card discharging device comprises a card loading assembly and a card lifting assembly; the card feeding device comprises a card feeding box, wherein a card feeding channel for transferring mahjong cards is arranged in the card feeding box, a card suction wheel is arranged at the card inlet of the card feeding channel, and a conveyor belt driven by a card feeding motor is arranged in the card feeding channel; the card feeding channel is curved in an arc shape, and an angle of 1° to 15° is formed between a card feeding direction of the card inlet and a card discharging direction of the card discharging port; in the same set of card picking and transporting systems, the card feeding device is arranged between a card storage slot of the card loading assembly and a card shuffling plate, the card feeding direction of the card inlet of the card storage slot and the card discharging direction of the card feeding outlet are arranged at an angle of 80° to 100°, and the card pushing direction of the card pushing head is consistent with the card feeding direction of the card inlet of the card storage slot. In this solution, the mahjong tiles are sucked up by the shuffling wheel of the card feeding device and pushed to the table of the mahjong machine by the card loading pusher. The conveying route of the mahjong tiles is roughly G-shaped, which makes the conveying path of the mahjong tiles (mainly the card storage slot) significantly extended, making it less likely to get stuck, less prone to malfunctions, and better in operating stability; at the same time, the mahjong machine can also be made thinner.

[0004] However, currently fully automatic mahjong machines basically only have four exits, and the two-layer mahjong machine can only be raised to the table from the four exits respectively. When playing cards, manual cutting and stacking of cards are still required, which is not only troublesome to operate, but also often results in incorrect cutting of cards, and the cards can only be reshuffled.

[0005] In order to solve this problem, existing technicians have invented an eight-mouth mahjong machine that can automatically cut and code cards. Although there are many types of eight-mouth mahjong machines after the development in recent years, they are basically divided into two categories:

[0006] 1) There are still four card outlets on the mahjong machine table. The mahjong machine divides the mahjong tiles in the card storage slot into two card loading slots to realize the function of an eight-mouth mahjong machine;

[0007] For example, the patent document with the publication number CN107320947A discloses a mahjong machine and its ramp card-discharging device and card-loading method, wherein the card-lifting slot, the card-storing slot and the card-feeding channel of the card-feeding device in the same group of card-picking and transporting systems are arranged in a G shape, and the card-feeding channel in one group of card-picking and transporting systems is located at the side and lower side of the card-lifting slot in another adjacent group of card-picking and transporting systems, so that the height of the mahjong machine host can be reduced; a cover plate that can be opened upward is provided, so that during the ascending process of the card-lifting support plate, the mahjong tiles on the edge of the card-lifting support plate can lift the cover plate, and after the card-lifting support plate is flush with the mahjong machine table top, the cover plate returns to its position, so that a large gap between the card-lifting support plate and the mahjong machine table top or the mahjong tiles on the edge collide with the mahjong machine table top. In this way, the cards can be loaded in stages, and the player can start playing cards immediately after the six and a half piles or thirteen mahjong tiles loaded for the first time are erected, which saves the process of manual card separation and arrangement, and the player operation is simpler and more convenient, and the entertainment experience is better. However, the patent uses a wire rope drive mechanism to drive the card pushing head, which has problems such as complex structure, inconvenient assembly and debugging, unstable card loading process, high manufacturing cost and short service life of the wire rope.

[0008] 2) There are eight card outlets on the mahjong machine table, and two conveyor tracks on one side of the mahjong machine. When loading cards, the mahjong tiles in the two conveyor tracks are pushed onto the mahjong machine table to complete the loading.

[0009] For example, a Chinese invention patent with publication number CN109248437 discloses a card feeding mechanism of an eight-mouth fully automatic mahjong machine, the mahjong machine comprising a frame, a large plate arranged in the frame, and two exits arranged on each side of the large plate; the card feeding mechanism comprises a starting card feeding track arranged on each side of the large plate, a first card feeding track and a second card feeding track arranged on each side of the large plate, the starting ends of the first card feeding track and the second card feeding track are both connected to the corresponding starting card feeding track, and the card feeding ends of the first card feeding track and the second card feeding track are respectively arranged corresponding to the two exits on the same side of the large plate; there are slidingly installed in the starting card feeding track and the first card feeding track The first card pushing head is slidably installed on the starting card feeding track and the second card feeding track; a driving structure is provided on the frame for driving the first card pushing head and the card pushing head to start from the starting card feeding track at the same time and reach their respective card feeding ends at the same time; although the card feeding mechanism of the patent realizes the simultaneous card feeding and card separation, saving the card separation time, but the large plate of the patent requires two tracks on each side, two card pushing heads and two groups of driving structures for driving the card pushing heads to move. The overall structure is relatively complex, and the patent uses a wire rope to drive the card pushing head, the wire rope motor has a large load, the steel wire is easy to shake and break, the card feeding process is not stable enough, and the service life of the wire rope is short.

[0010] And the Chinese invention patent with publication number CN101569794 discloses a double-push-card-lifting mechanism for an eight-mouth automatic mahjong table, including a lift seat, a motor, a lift plate assembly, a push plate assembly and a transmission assembly, wherein the motor, lift plate assembly, push plate assembly and transmission assembly are mounted on the lift seat; the push plate assembly includes: a cylindrical cam connected to the transmission assembly and rotated under the drive of the transmission assembly; a push plate, having a push plate bearing and a push plate guide shaft, the push plate bearing is connected to the push plate guide shaft through a push plate guide sleeve, the push plate bearing contacts the cam circumference of the cylindrical cam, and the push plate bearing reciprocates along the push plate guide shaft under the rotation of the cylindrical cam. Although the technical solution of this patent realizes the double-push-card-lifting process of the eight-mouth automatic mahjong table, the mechanism has many parts and components and the overall structure is complex.

[0011] And the patent application document with publication number CN107519637A discloses a mahjong machine and a card loading method thereof, the mahjong machine includes four groups of card picking and transporting systems arranged around a shuffling plate, the card picking and transporting systems include a card feeding device for picking up mahjong tiles one by one from the shuffling plate and delivering them, a card stacking device for stacking two mahjong tiles into one pile, a card pushing device for pushing mahjong tiles into a card storage slot, and a ramp card discharging device for delivering the arranged mahjong tiles in multiple piles onto the mahjong machine table along a slope, the ramp card discharging device includes a card loading component and a card raising component, the card loading component includes a card storage slot, the card storage slot is curved in a large angle arc, and the storage quantity of mahjong tiles in the card storage slot is increased; the card loading component and the card raising component in the same group of card picking and transporting systems are directly adjacent to each other. The above-mentioned mahjong machine can implement a method of loading mahjong tiles in stages. When storing mahjong tiles, the card feeding device picks up the mahjong tiles and pushes them into the card storage slot by the card pushing device; when the mahjong machine receives the first loading signal, the card lifting plate of the card lifting device descends, and the loading pusher first pushes a part of the mahjong tiles in the card storage slot (generally six and a half tricks or thirteen mahjong tiles) onto the card lifting plate, and the card lifting plate rises to load these mahjong tiles onto the tabletop, waiting for the player to take the mahjong tiles on the tabletop; after the mahjong machine receives the second loading signal, the card lifting plate descends here, and the loading pusher pushes the remaining mahjong tiles in the card storage slot onto the card lifting plate, and the card lifting plate rises to load the mahjong tiles onto the tabletop. By adopting this scheme of loading cards and pushing them twice in stages, the function of an eight-mouth mahjong machine can be realized using the existing four-mouth mahjong machine structure. However, since the loading card pusher occupies the position of one pile of cards in the card storage slot during the process of loading cards to the card raising device, the card storage slot length of 18-19 piles of cards is required for 17 piles of cards. When using a mahjong machine in this way to play larger cards, the required track length of the mahjong machine is longer, which cannot be achieved by mahjong machines of existing machine sizes. Therefore, it is necessary to minimize the length of the mahjong machine card storage slot.

[0012] And the invention patent publication with publication number CN108635827A records a card loading structure of a three-layer mahjong machine, including a circular single-layer card track and a circular double-layer card track which are overlapped and installed up and down, the single-layer card track is installed with a motor seat, the motor seat is installed with a second motor through a gear, the motor seat is installed with a first motor through a rotating shaft, the passive shaft on the motor seat is connected with a single-layer card turntable through a bearing, the teeth of the single-layer card turntable are engaged with the gear, a single-layer card lever is arranged on the single-layer card turntable, and a card adjustment circle and a double-layer card lever placed in the card adjustment circle are installed on the double-layer card track; after the three-layer cards enter the card track, the second motor drives the gear to drive the single-layer card turntable to rotate, and the cards of the single-layer card track are pushed to the mahjong machine table through the single-layer card lever of the single-layer card turntable; after the three-layer cards enter the card track, the first motor drives the rotating shaft to drive the double-layer card lever to rotate, and the cards of the double-layer card track are pushed to the mahjong machine table. The mahjong machine of the above structure stacks three mahjong tiles into one pile, divides one pile of mahjong tiles into a single layer (one tile) and a double layer (two tiles stacked), respectively, and then sends them to the mahjong machine tabletop after being sent to the single-layer tile track and the double-layer tile track. Such arrangement can effectively shorten the required mahjong machine track length. However, the occupied height of the upper tile structure of the above mahjong machine is relatively large, and the overall height of the mahjong machine using this structure is relatively large, especially when playing larger mahjong tiles, the mahjong machine of the existing machine size cannot be realized. On the other hand, two motors are used to directly or indirectly drive two pusher heads to push the mahjong tiles in the single-layer tile track and the double-layer tile track, which increases the structural complexity and control complexity of the mahjong machine and increases the production cost of the mahjong machine.

[0013] And a Chinese utility model with publication number CN208694238U discloses a track card separator and a mahjong machine, the track card separator includes a main track for carrying and parallel pushing a predetermined number of stacked mahjong tiles output by a stacking device, a card separation structure for separating the mahjong tiles transported by the main track into mahjong tiles to be caught and mahjong tiles to be played, a first sub-track for sequentially conveying the mahjong tiles to be caught separated from the main track to the first sub-track for orderly arrangement in the card grabbing area, a second sub-track for sequentially conveying the mahjong tiles to be played separated from the main track to the second sub-track for orderly arrangement in the card playing area, and a card pushing mechanism for pushing mahjong tiles, the card playing end of the main track is respectively connected to the card feeding end of the first sub-track and the card feeding end of the second sub-track, the card playing end of the first sub-track is connected to the upper card opening of the card grabbing area, and the card playing end of the second sub-track is connected to the upper card opening of the card playing area. The track card separator of the present invention allows mahjong tiles to be played to the card grabbing area and the card playing area at the same time, which is more convenient for players to operate and saves players' time. However, in the technical solution, the second sub-track is located below the first sub-track, so in order to sequentially transport the mahjong tiles separated from the main track to the card-discharging area, a second sub-track and a card-pushing mechanism for pushing the mahjong tiles are required, which is relatively complex in structure. In addition, the card-discharging end of the second sub-track is connected to the card-loading opening of the card-discharging area, and a card-lifting support plate is required in the card-discharging area. Since the second sub-track is located below, the swing angle of the card-lifting support plate is larger and the tilt angle when receiving the tiles is larger, so that the mahjong machines near the card-lifting support plate need a larger avoidance space to achieve a larger angle of lifting of the card-lifting support plate.

[0014] And the Chinese invention patent publication with publication number CN108635827A records a card loading structure of a three-layer mahjong machine, including a circular single-layer card path and a circular double-layer card path that are overlapped and installed up and down, the single-layer card path is installed with a motor seat, the motor seat is installed with a second motor through a gear, the motor seat is installed with a first motor through a rotating shaft, the passive shaft on the motor seat is connected with a single-layer card turntable through a bearing, the teeth of the single-layer card turntable are engaged with the gear, a single-layer card lever is provided on the single-layer card turntable, and a card adjustment circle and a double-layer card lever placed in the card adjustment circle are installed on the double-layer card path; after the three-layer cards enter the card path, the second motor drives the gear to drive the single-layer card turntable to rotate, and the cards on the single-layer card path are pushed to the mahjong machine table through the single-layer card lever. The card loading structure of the three-layer mahjong machine disclosed by the present invention is designed with a motor seat and two motors to push the single-layer cards and the double-layer cards respectively, which has the advantages of one structure and two effects, and is more practical and versatile. In the scheme, three cards are stacked up and down, and two motors are set to push the single-layer cards and the double-layer cards respectively, and a circular single-layer card track and a circular double-layer card track are set to overlap each other. When the mahjong tiles are pushed onto the single-layer card track and the double-layer card track, the card track bottom plate cuts in between the mahjong tiles; however, this structure easily causes the mahjong tiles to tilt during the process of pushing the card track, resulting in disorder and errors.

In this way, the inner and outer side walls of the card storage slot are respectively formed on different components, and the card loading pusher is arranged at the junction of the inner side wall and the bottom wall of the card storage slot. The structure is more reasonable and convenient to install, and the injection molding difficulty and manufacturing cost of the first card storage track 711, the second card storage track 712 and the third card storage track 713 are reduced.

[0078] In this embodiment, as a preference, the card loading drive mechanism uses a synchronous belt 78 to drive a card loading push head 72, including a first card loading motor, a synchronous belt 78 and a synchronous pulley installed on the card storage track member 710. The first card loading motor drives the synchronous pulley to rotate, and the synchronous belt 78 is engaged with the synchronous pulley. The synchronous belt 78 is an open-loop synchronous belt. The starting end of the synchronous belt 78 is fixed with a card loading push head 72. The first card loading motor drives the card loading push head 72 to move through the synchronous pulley and the synchronous belt 78, thereby driving the card loading push head 72 to move from the card inlet of the card storage slot 71 to the card outlet of the card storage slot 71 and push the mahjong tiles 10 in the card storage slot 71 to the card lifting support plate 73 and the mahjong machine table top 1. A synchronous belt track is provided on the card storage track member 710 to limit the moving route of the synchronous belt. It is also preferred to fix the card loading pusher at one end of the synchronous belt to save space and facilitate driving, and it is preferred that the first card loading motor is installed near the card outlet of the card storage slot to ensure that the card loading pusher has a larger thrust when pushing cards and to ensure that the synchronous belt moves smoothly in the synchronous belt track.

[0079] like Figure 4 and Figure 5 As shown, the synchronous belt track is arranged at the bottom of the card storage track member 710, and a card loading base 76 is fixed under the card storage track member 710, and the synchronous belt 78 is arranged between the card storage track member 710 and the card loading base 76.

[0084] Preferably, the length of the synchronous belt 78 is smaller than the length of the first guide groove 761. During the card-loading process, the first card-loading motor drives the synchronous belt 78 to move on the synchronous belt track and always stays in the first guide groove 761. Such a configuration makes full use of the narrow space between the card-loading base 76 and the card storage track member 710, so that the synchronous belt 78 does not need to be rolled into a pile during the card-loading process, thereby avoiding space conflict with the desktop tray descending push-type card-loading device 6.

[0085] Preferably, the first side wall 715 includes an integrally formed first section and a second section, wherein the first section is located on the inner side of the card storage slot and is consistent with the conveying route of the mahjong tiles 10 on the card storage slot 71, and the second section smoothly transitions with the first section and terminates on the outer side of the card storage slot, and the length of the second section is greater than the length of the mahjong tiles 10; such an arrangement avoids the position conflict between the card pushing head 51 of the stacking and pushing device 5 and the card loading pushing head 72 during the card stacking and pushing process, thereby achieving avoidance of the two.

The card-pushing path refers to a path for the card-loading pusher 72 to push the mahjong tiles 10 along the first card storage track 711, the second card storage track 712 and the third card storage track 713 to the card-lifting support plate 73 and the mahjong machine table top 1. Further preferably, when putting cards on the board, the card-putting pusher 72 is located on the outside of the first card-putting track 711, and the first card-putting motor drives the card-putting pusher 72 to first move inward for a section of avoidance path to the inner wall of the first card-putting track 711, and then move along the first card-putting track 711, the second card-putting track 712 and the third card-putting track 713 to move a card-pushing path to push the mahjong tiles 10 onto the card-lifting support plate 73 and the mahjong machine table 1.
