Description

Technical Field

[0001] The invention relates to the field of mahjong machines, and in particular to a card pushing and pulling mechanism and a mahjong machine. Background Art

[0002] Mahjong is a traditional mass entertainment and leisure activity. Existing automatic mahjong machines require the magnetic mahjong tiles in the shuffle tray to be picked up and stacked, then arranged, and finally sent to the mahjong table for players' entertainment.

[0003] The existing automatic mahjong machine usually uses two independent mechanisms to realize pushing and pulling cards. Its working principle is: after the double-layer mahjong tiles are stacked in the stacking slot, the mahjong tiles are pushed out by the motor-controlled push plate, and then reset, and the action is reciprocating. After all the mahjong tiles are stacked, the entire mahjong tiles are pulled onto the lifting mechanism by the pulling mechanism, and the pulling mechanism is reset by the reset mechanism after the pulling operation is completed. In this way, more driving motors need to be used, resulting in the inability to reduce the manufacturing cost, and the probability of failure is relatively high. In addition, the pulling mechanism has a long stroke, and a corresponding reset mechanism is required. Moreover, the reset mechanism cannot affect the normal operation of other mechanisms, and the internal space design requirements of the automatic mahjong machine are relatively high. Moreover, each side of the current mahjong machine usually uses an independent driving mechanism for driving each action (the traditional multi-port automatic mahjong machine needs to use more than a dozen motors or cylinders), which increases the manufacturing cost on the one hand, and the efficiency of installation and production is also low on the other hand, which also increases the difficulty of daily maintenance. At the same time, the large number of driving mechanisms also makes the equipment large and heavy, increasing the cost of storage and transportation.

[0004] Patent ZL201210537155.X discloses "A card loading mechanism for a mahjong machine", which uses a motor to drive a tensioned steel wire to drive the card pusher to pull or reset the card, without the need for an additional reset mechanism. However, since it uses a card pusher guide structure, and the card pusher is located on the upper inner side of the track, the friction between the card pusher and the card pusher guide is large during use, and the stability is poor. It is very easy to get stuck when turning, so it also has a track patch made of wear-resistant material with a smooth surface on the track. Moreover, this mechanism cannot be simply combined with the stacking slot to achieve multi-functional operation. This mechanism can only realize the function of pulling cards, but not the function of pushing cards. At the same time, the card lifting mechanism on each side of the existing mahjong machine requires an independent motor to drive, which will greatly increase the production cost.

[0005] The applicant has applied for "An Improved Fully Automatic Mahjong Machine" 201910673023.1, which records the card pulling assembly, which is driven by the gear at the top of the card path to move forward and backward. Since it moves along the rack, the motor needs to move with the card pulling assembly, the motor load is large, and the resistance is large when turning. And because the motor needs to move, more space needs to be reserved in the mahjong machine for the motor to move, which increases the difficulty of space design.

DETAILED DESCRIPTION

[0042] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] like Figure 1-11 As shown, the specific embodiment of the present invention is a card pushing and pulling mechanism, comprising a slider 1, a motor 2, and a track 3. A circular arc-shaped slide groove 301 is arranged below one side of the inner wall of the track 3. The slider 1 is embedded in the slide groove 301. The slider 1 can slide back and forth along the slide groove 301. The slider 1 and the slide groove 301 have the same curvature radius. The motor 2 is connected to the slider 1 through a rope 5.

[0044] Since the slider 1 and the slide groove 301 both adopt an arc structure with the same curvature radius, the slider 1 slides closely against the slide groove 301, and there is no jamming during the sliding process. The card pushing and pulling actions are smoother and more fluent, and the wear is also lower, the failure rate is greatly reduced, and the service life is greatly increased.

[0045] In order to further reduce friction and improve stability, an arc-shaped convex rail 304 is further provided in the slide groove 301, and an arc-shaped groove 103 is provided at the lower part of the slider 1. The groove 103 matches the convex rail 304, and the curvature radius of the groove and the convex rail is the same.

[0046] The slider 1 is also provided with a push plate 101 for pushing and loading cards on one side, and the track 3 is also provided with a stacking slot 7 on one side;

[0047] When pushing cards, the push plate 101 waits at one edge behind the stacking slot 7. When the mahjong tiles are stacked in the stacking slot 7, the motor 2 rotates forward, and the slider 1 drives the push plate 101 to slide forward to push the stacked mahjong tiles into the track 3. Then the motor 2 rotates in the reverse direction, and the push plate 101 resets to continue stacking cards, and the cycle is repeated until all mahjong tiles are pushed into the track 3.

[0048] When pulling the tiles, the push plate 101 is driven by the slider 1 to pull all the tiles forward along the track 3 until all the tiles are pulled into the designated area.

[0049] Traditionally, the stacking and pushing actions use a driving mechanism in conjunction with a sensor to work in conjunction, and then cooperate with an independent card pulling mechanism to pull the stacked mahjong tiles into the bridge board. This application organically combines the card pushing and pulling mechanism with the magnetic stacking slot, which optimizes the spatial design, reduces interference between the mechanisms, and makes the position layout more flexible. The stacking action does not require a motor drive (when the mahjong tiles fall, under the action of magnetism and gravity, the mahjong tiles can fall more accurately into the designated position of the stacking slot), and the card pushing action is achieved by the card pushing and pulling mechanism. The slider is located on the side of the track and will not hinder other actions.

[0050] The track 3 may be an integral injection-molded structure; the track 3 may also be composed of an inner side wall 302 and a track body 303 , with the inner side wall 302 and the track body 303 being snap-connected.

[0051] In order to achieve a simple and effective card stacking action, a card suction mechanism 8 is provided on one side of the card stacking slot 7, and the horizontal position of the bottom of the card stacking slot 7 and the horizontal position of the tail end of the card suction mechanism 8 are greater than the thickness of a mahjong tile;

[0052] The distance between the vertical position of the stacking slot 7 away from the card suction mechanism 8 and the vertical position of the tail end of the card suction mechanism 8 is greater than the length of a mahjong tile;

[0053] The bottom of the stacking slot 7 is paved with a magnetic object to ensure that the magnetic mahjong tiles lie in a directional manner, and the magnetic object is in an adsorption relationship with the opposite side of the magnetic mahjong tiles. A noise reduction layer is also paved on the magnetic object to reduce the noise generated when the mahjong tiles fall.

[0054] In order to effectively control the active position of the push plate and accurately complete the pushing and pulling actions, the tail end of the track 3 is connected to the card lifting mechanism 9, and the push plate 101 can pull the mahjong cards into the card lifting mechanism 9. At least three position sensors 10 that can sense the position of the push plate are also provided on the track 3. The position sensors can sense that the push plate is in the initial position, the pushing completion position, and the pulling completion position.

[0055] In order to accurately monitor the card stacking state and automatically control the timing of the push plate activity, at least one card stacking sensor for sensing the card stacking state is provided on one side of the card stacking slot.

[0056] The position sensor may be one or more of a Hall sensor, an infrared sensor or a travel switch, and the stacking sensor may be one or more of a Hall sensor, an infrared sensor or a gravity sensor.

[0057] In order to reduce costs and increase stability, the slider 1 and the slide 301 are both made of POM plastic material with self-lubricating function. POM is polyoxymethylene, commonly known as Saigang, with high strength and stiffness, good elasticity, and good wear resistance. It has excellent mechanical properties, with a specific strength of up to 50.5MPa and a specific stiffness of up to 2650MPa, which is very close to that of metal. POM has a small friction coefficient, good wear resistance, a large limit PV value, and good self-lubricating property.

[0058] In order to ensure smooth pushing process, a side plate 102 is also provided on one side of the push plate 101. During the pushing process, the side plate can effectively block the card suction mechanism from sending the mahjong cards into the stacking slot from the side, ensuring a smooth and coherent pushing process.

[0059] In order to simplify the structure and facilitate installation and maintenance, Figure 3 In the first embodiment, the rope 5 includes a pull rope 501 and a reset rope 502. The front end of the motor 2 is driven and connected to a synchronous wheel 6. One end of the pull rope 501 and the reset rope 502 are respectively installed in different wheel grooves of the synchronous wheel 6. When the motor 2 rotates, the pull rope 501 and the reset rope 502 move in opposite directions. When the motor rotates forward, the pull rope is wound and the reset rope is loosened, and the slider moves forward; when the motor rotates reversely, the reset rope is wound and the pull rope is loosened, and the slider moves backward and resets;

[0060] The other end of the pull rope 501 is installed in the forward direction of the slider 1, and the other end of the reset rope 502 is installed in the reset direction of the slider 1. A small pulley 4 for steering is also provided in the middle of the reset rope 502; the pull ropes and reset ropes around can be driven simultaneously by a synchronous wheel. The traditional card pulling mechanism and card pushing mechanism are two independent mechanisms, and the card pulling mechanism needs to be reset by an independent reset structure when resetting due to its long stroke. The present application realizes the two operations of pulling and resetting through one motor, eliminating the need for a separate reset structure, while taking into account the reset operations of the card pushing action and the card pulling action, and the forward and reset actions are smooth and accurate, the operation process is stable, the wear is small, and it is not easy to get stuck, and the production cost is low.

[0061] In order to facilitate layout and installation, Figure 8In the second embodiment, the rope 5 includes a pull rope 501 and a reset rope 502. The front end of the motor 2 is connected to a synchronous wheel 6. One end of the pull rope 501 and the reset rope 502 are respectively installed in different wheel grooves of the synchronous wheel 6. The other end of the pull rope 501 is installed in the forward direction of the slider 1, and the other end of the reset rope 502 is installed in the reset direction of the slider 1. When the motor 2 rotates, the pull rope 501 and the reset rope 502 move in opposite directions.

[0062] The pull rope 501 and the reset rope 502 are covered with a bendable sleeve 503 on the outside; the pull ropes and reset ropes on all sides can be driven simultaneously through a synchronous wheel. The sleeve can be bent to any arc, and the pull rope and the reset rope do not need to turn through a small pulley; through the guidance of the sleeve, the motor can be installed on the inside of the track or on the outside of the track, which greatly increases the installation flexibility, and the installation space is also larger, and the installation and maintenance difficulty is low. After being guided by the sleeve, all the 4 pull ropes and 4 reset ropes on all sides can converge on a synchronous wheel, and a motor can synchronously drive the card pushing and pulling mechanisms on all sides to push and pull cards. Further reduce costs and reduce weight.

[0063] When in use, the card suction mechanism transports the mahjong tiles to the vicinity of the stacking slot. The mahjong tiles fall into the stacking slot under the action of gravity and are magnetically adsorbed to the magnetic objects. When the gravity sensor senses that the mahjong tiles are double-layered, the stacking operation is completed; at this time, the motor drives the slider to move forward in a small area, and the push plate pushes the mahjong tiles in the stacking slot into the specified area in the track. When the position sensor in the middle senses the push plate, the pushing action is completed, and the motor reverses and resets the slider (the position sensor senses the push plate reset), and the cycle is repeated until all the mahjong tiles are stacked and pushed into the track; then the motor drives the slider to move along the arc of the track, and the push plate pushes all the mahjong tiles forward along the track into the card lifting mechanism. When the position sensor at the tail of the track senses the push plate, the pulling action is completed; finally, the motor reverses and resets the slider, that is, the two actions of pushing and pulling are completed by one slider.

[0064] A mahjong machine comprises a frame 11, a shuffling mechanism 12, a card suction mechanism 13, and a control console 14. The shuffling mechanism 12 is arranged in the middle of the frame 11, the control console 14 is located above the shuffling mechanism 12, a table top is also arranged on the top of the frame 11, and card suction mechanisms 13 are correspondingly installed around the frame 11, the tail end of the card suction mechanism 13 is connected to a card stacking slot 7, and the card stacking slot 7 is also connected to a card pushing and pulling mechanism 15, and the tail end of the card pushing and pulling mechanism 15 is connected to a card lifting mechanism 9.

[0065] In order to achieve stable lifting of mahjong tiles, the card lifting mechanism 9 includes a bridge plate 901, a lifting motor 902, a lever 903, and a linkage block 904. One end of the bridge plate 901 is hinged on the frame 11, and the linkage block 904 is fixedly connected to the lever 903. One end of the lever 903 is hinged on the frame 11, and the other end of the lever 903 is located below the bridge plate 901. The lifting motor 902 is driven and connected to the linkage block 904 through a driving rope 905. The driving rope 905 is arranged along the frame 11. The lifting motor 902 can drive the linkage block 904 and the lever 903 to rotate around the axis together. After rotation, the lever 903 can lift the bridge plate 901.

[0066] The bridge plate 901 is a magnetic material, and the mahjong tiles can be adsorbed to the bridge plate 901. The magnetic material can be a steel plate or a magnet. The mahjong tiles are easy to slide sideways on the inclined bridge plate. The traditional mahjong machine needs to set an independent limit block to prevent the sideways sliding of the mahjong tiles. The automatic mahjong machine has magnets inside the mahjong tiles. The magnetic adsorption effect can ensure that the mahjong tiles are firmly fixed on the bridge plate.

[0067] A pulley 906 is provided at the top of the lever 903, and a limit plate 907 is provided at one side of the lower part of the lever 903; the pulley can reduce friction, making the lifting and resetting processes smoother, while reducing the wear of the top of the lever on the bottom of the bridge plate. The limit plate can further ensure that the lever remains in position after it is raised to a specified angle, playing a limiting role to prevent the lever from turning too far and being unable to be reset.

[0068] A synchronization mechanism 908 is provided between the driving rope 905 and the lifting motor 902. After the lifting motor 902 drives the synchronization mechanism 908 to rotate, it can synchronously drive all the driving ropes 905 to move, and all the bridge plates 901 are lifted together. Since the present application adopts the method of driving the driving rope to drive the rotating block to lift the board, the driving rope has excellent flexibility and can be easily installed or turned in the frame. The driving rope can be easily gathered to one place and driven simultaneously by a driving motor through the synchronization mechanism. In order to facilitate the layout, a sleeve is provided on the outside of the driving rope, and the driving rope can move smoothly in the sleeve.

[0069] The linkage block 904 is a fan-shaped structure, and the driving rope 905 is fixed at one end of the outer arc of the linkage block 904. The driving rope 905 is wound around the outer arc of the linkage block 904, and the force arm remains unchanged when the driving rope 905 pulls the linkage block 904 to rotate. The linkage block can also be circular, square, trapezoidal, triangular or other arbitrary shapes, and the shape can be adjusted according to the rotation angle of the lever and the position of the rope.

[0070] The present application adopts a slider and a slide groove with the same radius of curvature, and the sliding process is continuous and smooth; at the same time, the slide groove is located below the inner wall, which has better sliding stability and will not hinder the card stacking action. By controlling the active range of the slider, a set of mechanisms can be used to achieve the two actions of pushing and loading cards, reducing the number of motors and effectively reducing the cost of production and manufacturing; at the same time, a reset rope and a pull rope are used to drive the push plate forward and backward with a motor, and a small pulley or sleeve is used to accurately and quickly realize the advancement and reset of the push plate; at the same time, a card stacking groove with a magnetic object is used, and the card stacking operation can be completed without a driving mechanism, and the structure is simple and easy to install and maintain; a position sensor is also provided The device and the stacking sensor can accurately grasp the position of the push plate and the stacking status, and can realize more precise automatic control; the present application adopts a driving rope to drive the lifting of the bridge plate, and only one motor is needed to complete the simultaneous lifting of the bridge plates on all sides, which can reduce the number of motors; the mahjong machine of the present application can save 3-8 motors compared with the traditional mahjong machine (the traditional mahjong machine generally requires about 16 motors, the stacking action of the present application does not require a motor, the pushing action and the loading action on all sides share a motor, and the bridge plates on all sides of the lifting action share a motor), which can greatly reduce the production cost, reduce the weight of the equipment, and reduce the storage and logistics costs.
