Abstract
Description
[Technical field]
[0001] The present invention relates to the technical field of mahjong machines, and more particularly to a rotary tile lifting mechanism and a mahjong machine. [Background technology]
[0002] In conventional mahjong machines, a tile stacking and pushing mechanism is usually installed, and the tile stacking and pushing mechanism is usually installed with a tile receiving stand, a tile pushing head and a driving motor, and the driving motor drives the tile receiving stand to move up and down and the tile pushing head to push out the tiles. Here, the tile receiving stand is located at the tile exit position of the tile transport mechanism. The working principle is that when the tile receiving stand is located at the upper tile receiving position, one mahjong tile falls from the tile exit of the tile transport mechanism onto the tile receiving stand, the tile receiving stand descends to the lower tile receiving position, another mahjong tile falls onto the previous one on the tile receiving stand, and then the pile of tiles made up of the two mahjong tiles is pushed into the tile rising track groove by the tile pushing head. When the tiles are raised, the tile-raising motor drives the tile-raising mechanism to move the mahjong tile pile in the tile-raising track groove onto the table.
[0003] The disadvantages of the above mahjong machine are the following (1) and (2).
[0004] (1) The structure of the tile stacking and pushing mechanism is complex and expensive.
[0005] (2) Since an independent drive motor is installed in each of the tile lifting mechanism and the tile stacking and pushing out mechanism, the number of motors is large, the control is complicated, and the cost is high. Summary of the Invention

[0020] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in more detail with reference to the drawings and embodiments hereinafter. It should be understood that the specific embodiments described herein are only for the purpose of interpreting the present invention, and are not intended to limit the present invention.
[0021] In describing the present invention, orientations or positional relationships indicated by terms such as "upper", "lower", "front", "rear", "inside", "outer", etc. are based on orientations or positional relationships shown in the drawings, and should be understood to be merely for the convenience and simplification of the description of the present invention, and should not be understood as limitations on the present invention, since they do not indicate or imply that the devices or elements shown have a specific orientation and must be constructed and operated in a specific orientation.
[0022] In the description of the present invention, unless otherwise clearly specified or limited, the terms "attached", "coupled" and "connected" should be understood in a broad sense, for example, a fixed connection may be an integral connection, a removable connection, an internal communication between two elements, a direct connection, or an indirect connection via an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to specific circumstances.
[0023] The mahjong machine of this embodiment includes four rotary tile lifting mechanisms shown in Figures 1 to 10. The rotary tile lifting mechanisms of this embodiment include a tile lifting table 20, a drive mechanism 10, a second swing lever 30, and a tile lifting drive member 40.
[0024] In this embodiment, as shown in Figure 6, the tile lifting table 20 includes a tile lifting table main body 21 and a ring-shaped tile lifting groove 22 surrounding the tile lifting table main body 21, and the ring-shaped tile lifting groove 22 has an entrance side and an exit side, the entrance side is located at the tile exit position of the tile transport mechanism 50, and the exit side is connected to a tile lifting plate (not shown).
[0025] A special feature of this embodiment is that a tile receiving position 23 is installed at the entrance side of the annular tile rising groove 22, and during the shuffling process, the mahjong tiles fall from the tile exit of the tile transport mechanism 50 to the tile receiving position 23. In this embodiment, a buffer pad 28 is installed at the tile receiving position 23 to reduce noise when the mahjong tiles fall to the tile receiving position 23. Here, the material of the buffer pad includes, but is not limited to, rubber, silica gel, felt and other materials.
[0026] In this embodiment, the tile lifting table main body 21 is provided with a motor mounting portion 24, a first hinge hole 25, and a second hinge hole 27. Here, the first hinge hole 25 and the second hinge hole 27 have a height difference in the height direction, and as shown in Figure 6, the tile lifting table main body 21 is provided with a protrusion 26, and the second hinge hole 27 is provided on the protrusion 26.
[0027] 7, the drive mechanism 10 of this embodiment includes a reversible drive motor 11, a first one-way mechanism 13, a second one-way mechanism 14, a first drive member 15, and a second drive member 16. Here, the first one-way mechanism 13 and the second one-way mechanism 14 are fitted in parallel to the output shaft 12 of the drive motor 11, the first drive member 15 is fitted in the first one-way mechanism 13, and the second drive member 16 is fitted in the second one-way mechanism 14.
[0028] A special feature of this embodiment is that the rotation directions of the first unidirectional mechanism 13 and the second unidirectional mechanism 14 are opposite to each other. In this way, when the drive motor 11 rotates in the forward or reverse direction, it can drive to rotate only one of the first drive member 15 and the second drive member 16, and when the rotation direction of the drive motor is switched, the other drive member starts to rotate.
[0029] The first one-way mechanism 13 and the second one-way mechanism 14 both adopt conventional mature one-way mechanisms, such as a one-way bearing, a one-way clutch, a one-way ratchet mechanism, etc., and the specific structure is not limited in the present application, but it is preferable to adopt a one-way bearing.
[0030] 8, in a preferred embodiment of this embodiment, the first driving member 15 of this embodiment is a first rocking lever, which includes a first rocking lever body 152, a connection base 151 located at one end of the first rocking lever body 152, and a driving unit 153 located at the other end of the first rocking lever body 152. Here, the connection base 151 is fitted into the first one-way mechanism 13. The shape of the driving unit 153 is not limited, and may be, for example, a general columnar structure, a protruding structure, a roller structure, or a rolling bearing.
[0031] Accordingly, the second rocking lever 30 that is compatible with the first rocking lever of this embodiment includes a second rocking lever body 32, a tile pushing head 31 located at one end of the second rocking lever body 32, and a hinge post 33 located at the other end of the second rocking lever body 32, as shown in FIG. 9. Here, the hinge post 33 is rotatably connected to the first hinge hole 25 of the tile lifting table body. Here, the second rocking lever body 32 is provided with a driving track groove 34 that is compatible with the driving unit 153, and preferably, the driving track groove 34 is annular, and the second rocking lever 30 is driven by the first rocking lever to rock back and forth around the hinge post 33. Note that the annular driving track groove 34 is a preferred embodiment of this embodiment, and other track groove shapes that can realize reciprocating rocking may be adopted.
[0032] As shown in Fig. 1, in the initial state, the tile pushing head 31 is located on the side away from the annular tile rising groove 22 of the tile receiving position 23, and when two mahjong tiles fall in order from the tile outlet of the tile transport mechanism 50 to the tile receiving position 23, the drive motor 11 is started and the first drive member 15 (first swing lever) is driven to rotate, and as shown in Fig. 5, based on the compatibility between the drive unit 153 and the drive track groove 34, the second swing lever 30 is driven to swing around the hinge post 33 to the state shown in Fig. 2, and the tile pushing head 31 pushes the tile pile 60 formed by stacking the two mahjong tiles into the annular tile rising groove. At this time, the drive motor 11 continues to rotate in the same direction, and since the drive track groove 34 is annular, the second swing lever 30 is driven to swing in the opposite direction to return to the initial state shown in Fig. 1. By repeating this process, all the mahjong tiles can be stored in the circular tile ascending groove.
[0033] As a preferred embodiment of this embodiment, as shown in Fig. 4, the second driving member 16 of this embodiment is a gear on which an external toothed ring 161 is installed. Accordingly, as shown in Fig. 10, the tile lifting driving member that matches this gear includes a driving body 41, an internal toothed ring 42 installed on the driving body 41, a tile lifting push-out part 44, a link 45 connecting the tile lifting push-out part 44 and the driving body 41, and a hinge shaft 43 coaxial with the internal toothed ring 42. The internal toothed ring 42 meshes with the gear, and the hinge shaft 43 is rotatably connected to the second hinge hole 27 of the tile lifting table body 21. When the driving motor 11 drives the gear (second driving member) to rotate, the tile lifting driving member is driven by the second driving member to rotate around the hinge shaft based on the meshing relationship between the internal toothed ring and the gear.
[0034] As shown in Fig. 3, when shuffling is completed and it is necessary to lift the tiles, the drive motor 11 drives the gear (second drive member) to rotate, and the rotation direction of the drive motor is opposite to that of the drive motor driving the first drive member 15. The tile lifting push-out part 44 pushes out the mahjong tile pile 60 in the annular tile lifting groove 22 from the outlet side, and when the tile lifting push-out part 44 rotates once and returns to the position shown in Fig. 1 and Fig. 2, the drive motor stops rotating.
[0035] In this embodiment, the tile pushing-up portion 44 and the tile pushing-up head 31 are installed with a radial offset from each other in the annular tile pushing-up groove 22. Preferably, as shown in Figure 9, the tile pushing-up head 31 is provided with an allowance groove 35 that allows the tile pushing-up portion 44 to pass through.
[0036] In short, the above is only a preferred embodiment of the present invention, and does not limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
