Mahjong tile feeding mechanism of mahjong machine

Abstract

The invention discloses a mahjong machine tile feeding mechanism which comprises a tile storage base provided with a tile storage channel and a tile feeding push head used for pushing mahjong tile queues located in the tile storage channel, and a movable bearing face used for storing the mahjong tile queues is formed in the tile storage channel. The movable bearing surface and the tile feeding push head respectively apply acting force to the mahjong tile queue from the bottom and the rear of the mahjong tile queue at the same time so as to realize tile feeding, and the moving speed of the movable bearing surface is smaller than or equal to or larger than that of the tile feeding push head. In the early stage of tile feeding, the movable bearing face can independently send mahjong tile queues to the tile outlet from the tile inlet of the tile storage channel, and the tile feeding push head can not participate at all; in the later mahjong tile feeding stage, the movable bearing surface and the mahjong tile feeding push head apply acting force to the mahjong tile queue from the bottom and the rear of the mahjong tile queue at the same time, so that the mahjong tile feeding resistance of the mahjong tile feeding push head is greatly reduced, and the mahjong tile feeding process is smoother.

Description

Technical Field

[0001] This invention belongs to the field of mahjong machine technology, specifically relating to a mahjong machine card-loading mechanism. Background Technology

[0002] The storage channels used in rotary mahjong machines are all curved in an arc shape with a large bending angle. During the process of loading the mahjong tiles (i.e., the loading pusher pushes the mahjong tiles stored in the storage channel to the lifting plate), the mahjong tiles will constantly change positions in the storage channel, resulting in a large friction with the bottom and side walls of the storage channel. This undoubtedly places higher demands on the torque of the loading motor.

[0003] To reduce the resistance exerted on the mahjong tiles by the tile storage channel, many solutions have emerged in the prior art. For example, Chinese utility model patent with publication number CN217246672U assembles side patches and bottom patches inside the tile storage channel, and provides raised ribs on the side patches and bottom patches to reduce the contact area between the mahjong tiles and the inner side and bottom surface of the tile storage channel.

[0004] For example, CN116785681A, CN219110816U and CN223220941U have a card-adding turntable in the center of the card storage channel and the card-adding pusher is directly placed on the card-adding turntable. When adding cards, since the card-adding turntable also rotates, the inside of the card storage channel will not generate resistance to the movement of mahjong tiles. However, the resistance exerted on the mahjong tiles by the bottom and outside (especially the bottom) of the card storage channel still exists.

[0005] While the above measures can reduce the resistance encountered by the mahjong tiles in the storage channel to some extent, the resistance mainly comes from the bottom of the storage channel. As long as the mahjong tiles move relative to the bottom of the storage channel, this resistance is unavoidable. This is because after long-term use, the stains on the surface of the mahjong tiles (from the mahjong machine table and the player) abnormally increase the friction (especially the friction between the mahjong tiles and the bottom of the storage channel) within the storage channel. Even with the above measures, the effect is minimal. Summary of the Invention

[0006] The purpose of this invention is to provide a card-feeding mechanism for a mahjong machine, which has low card-feeding resistance and low requirements for the card-feeding motor.

[0007] To achieve the above-mentioned objectives, the technical solution of the present invention is as follows:

[0008] A mahjong machine card-feeding mechanism includes a card storage base with a card storage channel and a card-feeding pusher for pushing a queue of mahjong tiles within the card storage channel. The card storage channel has a movable support surface for storing the queue of mahjong tiles. The movable support surface and the card-feeding pusher apply forces to the queue of mahjong tiles simultaneously from the bottom and rear of the queue, respectively, to achieve card-feeding. The moving speed of the movable support surface is less than, equal to, or greater than the moving speed of the card-feeding pusher.

[0009] This invention incorporates a movable support surface within the card storage channel, capable of moving along the channel's extension direction. During card placement, the moving support surface independently moves the mahjong tile queue from the inlet to the outlet of the storage channel, without the card-placement pusher participating. Furthermore, when pushing the mahjong tile queue from the outlet to the lifting plate, the moving support surface applies force from the bottom of the queue at the rear, while the card-placement pusher applies force from the rear. This combined force significantly reduces the resistance of the card-placement pusher, making the placement process smoother.

[0010] In this invention, the license plate pusher has two different working modes.

[0011] The first type: The card-adding pusher has a card-adding waiting position in front of the mahjong tile queue, where all mahjong tiles are stored on the movable support surface, and a card-adding position that goes around to the back of the mahjong tile queue to push the mahjong tile queue.

[0012] The second type: The card-adding pusher has a card-adding waiting position at the beginning of the card storage channel where all mahjong tiles are stored on the movable support surface, and a card-adding position at the rear of the mahjong tile queue to push the mahjong tile queue.

[0013] In the first working mode, the movement path of the license plate pusher is closed, while the movement path of the base can be either closed or open. During one license plate issuance process, the license plate pusher moves one full circle (under the license plate waiting position, the base remains stationary) or two full circles (under the license plate waiting position, the base moves). In the second working mode, the movement paths of the license plate pusher and the base can be either closed or open. During one license plate issuance process, the license plate pusher moves one full circle along its movement path.

[0014] In the aforementioned card-loading mechanism, the movable support surface can be provided by a base movably disposed within the card storage base, and the card storage channel is part or all of the movable path of the base; the movable support surface is provided by a number of continuously arranged rotating rollers that are rotatably connected to the card storage base, and all rotating rollers rotate in the same direction.

[0015] When a base is used to provide a movable support surface, the bottom surface of the tile storage channel itself remains static. When a continuous rotating roller is used to provide the support surface, the bottom surface of the tile storage channel itself is dynamic. Both methods can provide a movable support surface that achieves the purpose of this invention; however, from a cost perspective, it is preferable to use a base to provide the movable support surface. In this case, when waiting for tiles to be added, the base and the tile queue are relatively stationary. Only when the tile adding pusher is added will the tile queue move relative to the base.

[0016] In this invention, the base can be made of rigid or flexible material, and there are no special requirements for this. The moving path of the base can be closed, either horizontally or vertically, in which case the base moves circumferentially along the moving path; the moving path of the base can also be open, in which case the base moves from the starting end of the card storage channel to the end and then returns along the same path (i.e., moves back and forth along the moving path).

[0017] This invention does not have special requirements regarding the closed state of the movement path of the base and the card-adding pusher; however, it is easier for the base and the card-adding pusher to return to their initial positions when the movement path is closed. Therefore, preferably, the base moves along a closed path under drive, and the card storage channel is part of this path and has a card inlet and a card outlet.

[0018] As a further preferred embodiment, the path is circular, and the base is circular or arc-shaped and moves circumferentially along the path;

[0019] The license plate pusher is driven to rotate circumferentially around a central point, which coincides with the center of the path.

[0020] It should be noted that, in this invention, the closed state of the base support moving path and the closed state of the license plate pusher moving path are not necessarily the same. Except for the preferred case mentioned above where both moving paths are in a closed state, it is also applicable to this invention if one is closed and the other is not closed, or if both are closed.

[0021] Regardless of the operating mode of the license plate pusher, in this invention, the power sources for the license plate pusher and the base can be the same or different; obviously, in the most preferred case, the same drive unit is used to drive the license plate pusher and the base, and in this case, the movement paths of the license plate pusher and the base are preferably both circular. In this case, the drive unit includes:

[0022] Motor registration;

[0023] The base is connected to the drive gear fixedly connected to the output shaft of the motor;

[0024] The license plate issuing turntable is driven by the active gear, and the license plate issuing push head is located on the outer periphery of the license plate issuing turntable.

[0025] As a further preferred embodiment, the license plate issuing turntable is rotatably connected to the license plate storage base, and the path is located on the outer ring of the license plate issuing turntable;

[0026] The plate-mounting turntable has an upper transmission gear ring that meshes with the drive gear, and the base has a lower transmission gear ring that meshes with the drive gear. The inner diameters of the upper and lower transmission gear rings may be the same or different.

[0027] To prevent the mahjong tiles or tile stacks on the base from coming into contact with the opposite sides of the tile storage channel (contact would create resistance to tile placement), the inner periphery of the base in this invention has an upwardly folded inner edge.

[0028] Alternatively, the outer periphery of the base has an upwardly folded-out edge;

[0029] The mahjong tiles stored on the base are located either on the outside of the inner folded edge or on the inside of the outer folded edge;

[0030] The height of the inner folded edge and / or the outer folded edge is less than the height of a mahjong tile. At least at the location of the tile storage channel, the tile loading mechanism is provided with protective components located on the inner and / or outer sides of the base to prevent mahjong tiles from falling.

[0031] The inner and outer folded edges can be set simultaneously, or only one of them can be set; setting both simultaneously is obviously better. However, in order to allow the mahjong tiles to smoothly enter and exit the storage channel, and also to avoid other parts (such as the stacking and pushing components), the height of the inner and outer folded edges does not need to be too high. In this case, protective parts are needed to prevent the tile stacks from falling off the sides of the base. In fact, protective parts do not need to be set separately. The tile-loading turntable located outside the inner folded edge can serve as a protective part, while the inherent outer shell of the tile storage base at the location of the outer folded edge can serve as a protective part. A patch can also be added if needed.

[0032] Since the base is a hollow ring-shaped material, it needs to be positioned. In this invention, a guide is provided between the base and the card storage base to ensure that the base always moves along the path, and a limiting member is provided on the card storage base to prevent the base from deviating from the path.

[0033] The guide and limiting components can take various forms, and those skilled in the art can customize them according to specific needs. Preferably, the guide includes an annular groove recessed in the storage base, and the bottom surface of the base is provided with an annular rib embedded in the annular groove;

[0034] The limiting component includes at least one column rotatably connected to the card storage base. The column has a lower stabilizing gear meshing with the lower transmission gear ring and a protruding edge abutting against the top surface of the base. The column also has an upper stabilizing gear meshing with the upper transmission gear ring of the card loading turntable.

[0035] It can be seen that overcoming the friction between the mahjong tiles and the storage channel is much less strenuous than overcoming the friction between the base and the storage base. By dripping lubricating oil into the annular groove or by configuring components such as ball bearings, the movement of the base will be smoother.

[0036] Furthermore, the lower stabilizing gear meshing with the lower drive gear ring can accurately lock the base in a preset position, preventing unnecessary slippage of the base along the path; while the raised edge can restrict the base in the vertical direction. In this invention, the raised edge can be an outward protrusion relative to the column itself, or it can be an outward protrusion corresponding to the tooth gap of the lower stabilizing gear; both methods can achieve their function.

[0037] Compared with the prior art, the beneficial effects of this invention are reflected in the following aspects:

[0038] This invention features a base support on the card storage base, which can move along a path through the card storage channel. During card storage, the mahjong tiles or tile stacks are not directly stored into the channel, but rather on the base support within the channel. When placing tiles, the moving base support independently moves the mahjong tile queue from the inlet to the outlet of the storage channel, without the tile-push head participating. During this process, the mahjong tile queue and the base support remain relatively stationary, and there is no resistance between them regardless of whether the tiles are clean or soiled. Furthermore, when it is necessary to push the mahjong tile queue from the outlet of the storage channel to the tile-lifting plate, the moving base support applies force from the bottom of the queue at the rear, while the tile-push head applies force from the rear. These forces in both directions significantly reduce the tile-push head's resistance, making the tile-push process smoother. Attached Figure Description

[0048] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0049] Example 1

[0050] like Figure 1 and Figure 2 As shown in the figure, this embodiment of a mahjong machine card feeding mechanism includes a card storage component 1 and a card feeding component 2, wherein the card storage component 1 is used to store a queue of mahjong tiles, and the card feeding component 2 is used to push the queue of mahjong tiles in the card storage component 1 to the card raising plate.

[0051] The card storage component 1 in this embodiment includes a card storage base 11, such as Figure 1 , Figure 2 and Figure 3 As shown, a closed circular moving path 100 is formed inside the card storage base 11. Card inlet 101 and card outlet 102 are formed at different circumferential positions of the moving path 100. The part of the moving path 100 between the card inlet 101 and the card outlet 102 is the card storage channel 103. It can be seen that the card storage channel 103 is a part of the moving path 100.

[0052] like Figure 1 and Figure 2 As shown, a base 12 is provided on the activity path 100. The function of the base 12 is to provide a movable support surface. The part of the movable support surface that is in the card storage channel 103 or moved into the card storage channel 103 is used to store mahjong tiles and assist in the placement of tiles. Therefore, the length of the base 12 is not less than the length of the mahjong tile queue, and usually not less than the length of the card storage channel 103.

[0053] In actual operation, the base 12 can be arc-shaped, meaning the length of the base 12 is less than the length of the moving path 100, and the base 12 moves along the moving path 100; or it can be... Figure 1 and Figure 2 As shown in the circular shape, the length of the base 12 is the same as the length of the moving path 100. The base 12, which moves along the moving path 100, actually rotates around the center of the moving path 100.

[0054] After the mahjong tiles are stored on the base 12, the base 12 moves or rotates along the movement path 100 to deliver the mahjong tiles to the dispensing opening 102 of the storage channel 103. However, in the arc-shaped storage channel 103, the mahjong tiles need to constantly change position according to the direction of the storage channel 103. To avoid the mahjong tiles on the base 12 contacting the sides of the storage channel 103 and thus causing friction, in this embodiment, as shown... Figure 4 As shown, the inner and outer peripheries of the base 12 have an inner folded edge 121 and an outer folded edge 122 that are folded upwards, respectively, and the mahjong tiles stored on the base 12 are located between the inner folded edge 121 and the outer folded edge 122.

[0055] This embodiment does not have strict requirements on the height of the inner folded edge 121 and the outer folded edge 122. Considering the need to avoid some other components inside the tile storage base 11, this embodiment sets the height of the inner folded edge 121 and the outer folded edge 122 to be less than the thickness of a mahjong tile. However, because the height of the inner folded edge 121 and the outer folded edge 122 is relatively low, when the base 12 stores a tile stack, there is a risk that the mahjong tiles on top of the tile stack may fall to the sides.

[0056] Therefore, protective components are provided on the card storage base 11 at least on both sides of the card storage channel 103. The function of the protective components can be performed by the inherent structure in the card storage assembly 1, such as the protective baffle 111 on the outer periphery of the card storage base 11 and the disc-shaped structure (such as the card loading turntable 21) in the center of the card storage base 11, etc. In this embodiment, the protective baffle 111 (a patch 112 can be added to the inner side of the protective baffle 111 as needed to adjust the width of the card storage channel 103) and the card loading turntable 21 are provided on the entire movement path 100 of the base 12, and only the card inlet 101 and the card outlet 102 of the card storage channel 103 need to be opened on the protective baffle 111.

[0057] In this embodiment, the movement or rotation of the base 12 is driven by a drive unit. For example... Figure 4 and Figure 7As shown, the drive unit used in this embodiment includes a motor (not shown in the figure) and a drive gear 13 rotatably mounted on the card storage base 11. The drive gear 13 is connected to the output shaft of the motor. The inner periphery of the base 12 has a lower transmission gear ring 123, which can directly mesh with the drive gear 13 for transmission (e.g., Figure 7 As shown, the base support 12 can also be driven by a transmission gear and a drive gear 13. Those skilled in the art can also use other drive units to drive the base support 12; this embodiment has no special requirements in this regard.

[0058] It can be seen that the base 12, which is in the shape of a ring or arc and can move relative to the card storage base 11, is very unstable. It is necessary to set a guide between the base 12 and the card storage base 11 to make the base 12 always move along the path, and a limiting member to prevent the base 12 from leaving the path.

[0059] Guide components and limiting components come in various forms, and those skilled in the art can configure them according to specific needs. For example... Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the guide component used in this embodiment includes an annular groove 113 recessed in the tile storage base 11, and an annular rib embedded in the annular groove 113 protruding from the bottom surface of the base 12. It can be seen that overcoming the friction between the base 12 and the tile storage base 11 is significantly easier than overcoming the friction between the mahjong tiles and the tile storage channel 103. Further, by applying lubricating oil or installing ball bearings in the annular groove 113, the movement of the base 12 will be smoother and less strenuous. However, since the mahjong tile queue will eventually leave the tile storage channel 103, relative movement will still occur between the mahjong tiles and the base 12. To reduce the friction between the mahjong tiles and the base 12, such as... Figure 4 , Figure 5 and Figure 6 As shown, a recessed area 124 is formed on the top surface of the base 12. The recessed area 124 is annular and located at the center of the base 12. While ensuring that the base 12 can stably support the mahjong tiles, it reduces the contact area between the mahjong tiles and the base 12, which helps to reduce the resistance during the tile-playing process.

[0060] like Figure 7As shown, the limiting components used in this embodiment include three columns 14 rotatably connected to the storage base 11. Each column 14 is provided with a lower stabilizing gear 142 that meshes with the lower transmission gear ring 123 of the base 12, and a protruding edge 141 that abuts against the top surface of the base 12. The three columns 14 securely limit the base 12 on the moving path 100 through the lower stabilizing gear 142, ensuring that the center of the base 12 does not shift and that it does not slip during movement; the protruding edge 141 prevents the base 12 from coming off vertically. In this embodiment, the protruding edge 141 may be outwardly protruding relative to the column 14 itself, or it may be outwardly protruding relative to the tooth gap of the lower stabilizing gear 142, i.e. Figure 7 As shown, both methods can achieve the desired function.

[0061] like Figure 1 and Figure 2 As shown, the license plate loading assembly 2 in this embodiment includes a license plate loading turntable 21 rotatably connected to the license plate storage base 11. A license plate loading pusher 22, which extends into the license plate storage channel 103, is fixedly disposed on or integrally formed on the outer periphery of the license plate loading turntable 21. In this embodiment, the movement path of the license plate loading pusher 22 is also a closed loop. Therefore, the drive unit in this embodiment can not only drive the base 12 to work, but also drive the license plate loading turntable 21 to work.

[0062] like Figure 8 As shown, the bottom surface of the license plate turntable 21 has an upper transmission gear ring 211 that meshes with the drive gear 13. The inner diameters of the upper transmission gear ring 211 and the lower transmission gear ring 123 can be the same or different; in this embodiment, they are the same, so that the base 12 and the license plate turntable 21 can rotate synchronously at the same speed. In addition, the column 14 is also provided with an upper stabilizing gear 143 that meshes with the upper transmission gear ring 211 of the license plate turntable 21, so that the base 12 and the license plate turntable 21 can be tightly joined together to form a unified moving unit.

[0063] The working principle of the mahjong machine card-loading mechanism in this embodiment is as follows:

[0064] The motor starts, the base 12 and the card-loading turntable 21 begin to rotate, and the card-loading pusher 22 also moves forward along the card storage channel 103; at the same time, the stacking pusher assembly 200 (such as...) at the beginning of the card storage channel 103... Figure 9As shown, the tile stacks or mahjong tiles are pushed one by one onto the base tray 12. The tile stacks or mahjong tiles remain relatively stationary with the base tray 12 and move with the base tray 12 to the tile outlet 102 of the tile storage channel 103. Meanwhile, the tile pusher 22 is always at the front of the mahjong tile queue. During this process, the tile stacks may not be tightly arranged and there may be gaps. When the first tile stack or the first mahjong tile arrives at the tile outlet 102 of the tile storage channel 103, due to the obstruction of the tile lifting plate auxiliary structure (not shown in the figure, but an inherent structure of the mahjong machine), the tile stack or mahjong tile does not move with the base tray 12 and the tile pusher 22. The card pusher 22 continues to move forward, stopping at the card outlet 102 of the card storage channel 103 until all the card stacks (or card stacks and mahjong tiles) are closely arranged. During this process, the base 12 and the card pusher 22 continue to move along the activity path 100 until the card pusher 22 rotates 360° and returns to the end of the mahjong tile queue. At this time, the card pusher 22 applies a force from the end of the mahjong tile queue, while the base 12 applies a force from the bottom of the mahjong tile queue. Under the two forces, the mahjong tile queue is pushed out of the card storage channel 103 and onto the card lifting plate.

[0065] Example 2

[0066] This embodiment describes a mahjong machine card-loading mechanism, whose structure is basically the same as that of Embodiment 1. The difference lies in that the card-loading turntable 21 and the base 12 are driven by different drive units. The structures of the two drive units are still the same, except that two motors are installed on the card storage base 11, and each motor is equipped with a drive gear 13. One drive gear 13 meshes with the base 12 for transmission, and the other drive gear 13 meshes with the card-loading turntable 21 for transmission. Both motors are connected to the control unit, and the sensor located in the card storage channel 103 for detecting whether all the mahjong tiles have entered the card storage channel 103 is also connected to the control unit.

[0067] Similarly, the lower stabilizing gear 142 and the upper stabilizing gear 143 are fixedly mounted on different columns 14, or they are still mounted on the same column 14, but at least one of them is rotatably connected to the column 14. If necessary, the upper stabilizing gear 143 can be omitted.

[0068] The working principle of the mahjong machine card-feeding mechanism in this embodiment is as follows:

[0069] The motor driving the base 12 to move is activated, and the base 12 moves along the active path 100. Simultaneously, the stacking and pushing assembly at the beginning of the card storage channel 103 pushes the card stacks or mahjong tiles one by one onto the base 12. The card stacks or mahjong tiles remain relatively stationary with the base 12, moving with it to the card outlet 102 of the card storage channel 103. Meanwhile, the card-raising pusher 22 remains at the beginning of the card storage channel 103 (behind the stacking and pushing assembly), maintaining its position. During this process, the card stacks may not be tightly arranged, with gaps between them. When the first card stack or the first mahjong tile arrives at the card outlet 102 of the card storage channel 103, due to the lifting plate auxiliary structure... (Not shown in the figure, but is an inherent structure of the mahjong machine) The block or mahjong tile does not continue to move forward with the base 12 and the tile pusher 22, but stops at the tile outlet 102 of the storage channel 103; until all the block (or block and mahjong tile) are closely arranged (detected by the sensor); at this time, the control unit starts the motor used to drive the tile turntable 21 to rotate, and the tile pusher 22 begins to move along the storage channel 103 to the end of the mahjong tile queue. The tile pusher 22 applies force from the end of the mahjong tile queue, while the base 12 applies force from the bottom of the mahjong tile queue. Under the two forces, the mahjong tile queue is pushed out of the storage channel 103 and onto the tile lifting plate.

[0070] In this embodiment, when the license plate is being placed, the moving speed of the license plate pusher 22 can be less than, equal to or greater than the moving speed of the base 12. This embodiment has no special requirements in this regard.

[0071] Example 3

[0072] This embodiment provides a mahjong machine card feeding mechanism, whose structure is basically the same as that of Embodiment 1 or 2. The difference is that the movement path 100 of the base 12 on the card storage base 11 is not closed, but is arc-shaped and the central angle of the arc is greater than 180°. Correspondingly, the base 12 is also arc-shaped, but the length of the base 12 is shorter than the length of the movement path 100.

[0073] Meanwhile, in this embodiment, the base 12 and the license plate pusher 22 are also driven by different drive units, just like in embodiment 2.

[0074] During operation, to ensure that all tiles or mahjong tiles pushed out by the stacking and pushing component are caught by the base support 12, it can be set so that the base support 12 only works when the stacking and pushing component pushes tiles. This minimizes the gaps between tiles (or between tiles and mahjong tiles, or between mahjong tiles) caused by the movement of the base support 12. To ensure that the base support 12 still supports the end of the mahjong tile queue (the head of the queue is already on the tile-raising plate) when the tile-adding pusher 22 pushes, the moving speed of the tile-adding pusher 22 can be set to be greater than the moving speed of the base support 12, so that the tile-adding pusher 22 reaches the end of the mahjong tile queue as quickly as possible and begins the tile-adding process.

[0075] After a license plate is placed, the base support 12 moves in the opposite direction along the activity path 100 and returns along the original path; while the license plate pusher 22 can continue to move forward, return to the starting point after rotating 360°, or return along the original path like the base support 12.

[0076] Example 4

[0077] This embodiment describes a mahjong machine card-loading structure, which is basically the same as that in embodiment 3. The difference is that the card storage base 11 is rotatably connected to several rotating rollers that are continuously arranged in the card storage channel 103. The rotation direction of all the rotating rollers is the extension direction of the card storage channel 103. When the rotating rollers rotate synchronously, the mahjong tiles can move forward autonomously. In this way, the top surfaces of all the rotating rollers form a movable support surface.

[0078] The configuration and transmission method of the rotating roller can be referred to CN116889721A, and will not be elaborated in this embodiment. In this embodiment, after one loading, the rotating roller does not need to perform the same return operation as the base 12; it only needs to stop rotating.
