Description

Technical Field

[0001] The invention relates to the technical field of automatic mahjong machines, and in particular to a card loading device, a mahjong machine and a card loading method. Background Art

[0002] The card loading device used in the existing fully automatic mahjong machine is extremely complicated. The card loading device includes a card loading bracket, a card suction wheel, a card output wheel, a tensioning wheel and a tensioning mechanism, a conveyor belt and a driving wheel. The entire card loading device has many parts and is complicated to assemble. It occupies a large space. In addition, there are many failures caused by the tensioning mechanism and the conveyor belt during use, which brings many quality problems to the entire mahjong machine. In addition, due to the large space occupied, the card loading time of the entire machine is greatly affected.

[0003] In view of this, a Chinese invention patent with publication number CN108786098A discloses a card feeding device of an automatic mahjong machine and an automatic mahjong machine. The automatic mahjong machine with this structure simplifies the structure of the card feeding device (i.e., the card loading device), which only includes a card feeding bracket, a card suction wheel, and a card blocking member, wherein the card suction wheel is used to absorb the mahjong tiles in the shuffling plate and transport the mahjong tiles absorbed thereon by rotation, and the card blocking member is used to separate the above-mentioned rotating and transported mahjong tiles from the card suction wheel. The separated mahjong tiles are sent out of the card feeding bracket under the action of gravity and the thrust of the card suction wheel and directly enter the card receiving plate of the card stacking device.

[0004] The mahjong machine card feeding device of the above structure changes the existing way of loading cards through a conveyor belt, greatly simplifies the structure of the card feeding device, reduces the space occupied, and greatly reduces the transmission path of the mahjong tiles during the loading process, thereby achieving a series of technical effects such as cost saving, simplified structure, space saving, improved assembly efficiency, shortened loading time and lower structural failure rate.

[0005] However, the mahjong machine card delivery device of the above structure still has very large technical defects, as follows:

[0006] (1) After being separated, the mahjong tiles leave the card delivery bracket and enter the card receiving plate by the gravity of the tiles themselves and the magnetic thrust of the card suction wheel. However, because the card suction wheel rotates continuously, the magnetic thrust it applies is intermittent. Therefore, there is a lack of stable and continuous driving force in the process of the tiles leaving the card delivery bracket. The gravity of the tiles themselves naturally generates a certain friction resistance, which causes the tiles to fail to enter the card receiving plate smoothly or the time for each tile to enter the card receiving plate is not uniform. Since the loading device, stacking mechanism, and lifting mechanism all need to work together, once a tile fails to enter the card receiving plate smoothly or the time it takes to enter is prolonged, the automatic control system of the automatic mahjong machine becomes disordered, which in turn causes the mahjong machine to malfunction. The failure rate of this structure is very high and it is not feasible at all.

[0007] (2) Although a card-discharging guide wheel is provided behind the card-blocking member in the above structure, the mahjong cards still pass through the card-discharging guide wheel by their own gravity and the magnetic thrust of the card-absorbing wheel, which substantially increases the resistance during the card-discharging process. When the card-discharging guide wheel is fixed, excessive resistance will further increase the difficulty and accuracy of the mahjong cards entering the card-receiving plate. When the guide wheel is rotatable, it is driven to rotate by the friction of the mahjong cards, which also increases the resistance to the card-discharging of the mahjong cards. Since each mahjong card cannot be completely consistent, when the mahjong cards rely on gravity to drive the guide wheel to rotate, the time consistency of entering the card-receiving plate is also poor. This undoubtedly increases the control difficulty and the failure rate for the automatic control system. Summary of the invention

[0008] In order to solve the technical problems existing in the prior art, the technical solution provided by the present invention is as follows: a license plate device, comprising at least:

[0009] Plate bracket;

[0010] A card-absorbing wheel, which is disposed on the card-loading bracket and is provided with a first driving device for driving the card-absorbing wheel to rotate; and

[0011] A separation mechanism, the separation mechanism is adjacent to the card suction wheel and is configured to separate the mahjong tiles absorbed by the card suction wheel from the card suction wheel;

[0012] It also includes a card feeding wheel, which is adjacent to a side of the separation mechanism away from the card suction wheel and is equipped with a second driving device for driving the card feeding wheel to rotate, and the card feeding wheel is configured to transport the mahjong tiles on the separation mechanism.

[0013] In a preferred embodiment, the upper surface of the separation mechanism is configured to have a certain length in the conveying direction of the mahjong tiles, and the certain length does not exceed the length of the mahjong tiles themselves in the conveying direction.

[0014] In a preferred embodiment, the upper surface of the separation mechanism is configured to have a high position, and the upper surface of the separation mechanism forms an inclined surface that gradually decreases from the high position toward a side of the card feeding wheel.

[0015] A preferred embodiment further comprises an auxiliary card feeding wheel, which is arranged in the area of ​​the separation mechanism through which mahjong tiles pass, and the auxiliary card feeding wheel is arranged parallel to the card feeding wheel and can rotate around its own axis.

[0016] In a preferred embodiment, the auxiliary card feeding wheel rotates synchronously with the card feeding wheel; or, a synchronous belt is provided between the auxiliary card feeding wheel and the card feeding wheel.

[0017] In a preferred embodiment, the first driving device and the second driving device are the same driving device, and a transmission mechanism is arranged between the rotating shaft of the card delivering wheel and the rotating shaft of the card absorbing wheel; the card absorbing wheel is arranged on the output shaft of the first driving device, and the transmission mechanism includes a first gear coaxially connected to the card absorbing wheel, a second gear coaxially connected to the card delivering wheel, and an intermediate gear respectively meshing with the first gear and the second gear.

[0018] A preferred embodiment further comprises a third gear coaxially connected to the auxiliary card feeding wheel, wherein the third gear meshes with the intermediate gear.

[0019] A preferred embodiment further includes a card handling bracket arranged opposite to the card loading bracket, a card output channel is formed between the card handling bracket and the card loading bracket, the card suction wheel is located in the card output channel on the side close to the separation mechanism, and the card delivery wheel is located in the card output channel close to the exit.

[0020] A mahjong machine comprises at least four sets of the card loading devices, which are respectively arranged on the four sides of the mahjong machine; and also comprises a card stacking mechanism corresponding to the card loading devices one by one, the card stacking mechanism is arranged on the exit side of the card output channel and adjacent to the card feeding wheel.

[0021] A method for loading cards on a mahjong machine comprises at least the following steps:

[0022] The card suction and conveying step, wherein the card suction wheel absorbs the mahjong tiles onto the card suction wheel and conveys the mahjong tiles by rotating the card suction wheel;

[0023] a separation step, wherein the separation mechanism separates the mahjong tiles adsorbed on the card suction wheel, and under the push of the card suction wheel, the separated mahjong tiles move from the side of the separation mechanism close to the card suction wheel along the upper surface of the separation mechanism to the side of the card delivery wheel; and

[0024] In the card delivery step, the mahjong tiles separated from the card suction wheel pass through the separation mechanism, and then the mahjong tiles are delivered to the stacking mechanism through the rotation of the card delivery wheel.

[0025] Compared with the prior art, the card loading device of the present application and the mahjong machine including the card loading device have the following beneficial effects:

[0026] (1) Compared with the traditional belt-type card-loading device, it has a simple structure and low cost, which can effectively avoid the defect of high failure rate of the belt-type card-loading device. At the same time, the distance of mahjong card transmission is short, the card-loading efficiency is higher, and the noise is smaller.

[0027] (2) Compared with the card loading device disclosed in CN108786098A, since a card feeding wheel with an independent driving device is provided, during the transportation process of the mahjong cards from the separation mechanism to the stacking mechanism, there is a continuous driving force directly acting on the bottom surface of the mahjong cards, rather than relying on the gravity of the mahjong cards themselves. In this way, the mahjong cards can smoothly leave the separation mechanism and enter the stacking mechanism. Moreover, since the driving force they receive is continuous and stable, the time when all mahjong cards leave the separation mechanism and enter the stacking mechanism is basically the same. In this way, the control difficulty of the coordination between the various mechanisms of the automatic mahjong machine is reduced, and the failure rate of the system will also be greatly reduced.

[0028] (3) The upper surface of the separation mechanism is configured to have a certain length in the conveying direction of the mahjong tiles, which can more stably control the playing posture of the mahjong tiles, improve the consistency and reliability of the smooth playing of the mahjong tiles, and thus reduce the failure rate.

[0029] (4) Since the length of the upper surface of the separation mechanism along the conveying direction does not exceed the length of the mahjong tiles themselves in the conveying direction, the conveying driving force between the card suction wheel and the card delivery wheel can be effectively connected, avoiding the interruption of the conveying driving force, making the action of the mahjong tiles entering the stacking mechanism more reliable and stable.

[0030] (5) The card suction wheel and the card delivery wheel are driven by the same drive device, which has the advantages of high system integration, high utilization rate of the drive device and cost saving. At the same time, fewer drive devices are of great significance in reducing the failure rate in automation equipment. BRIEF DESCRIPTION OF THE DRAWINGS

For example, it can be a fixed connection, an integral connection, or a detachable connection; it can be the internal connection of two components; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] Embodiment 1

[0048] The present embodiment discloses a license plate device, the structure of which is as follows: Figure 1-2As shown, it includes a card loading bracket 10, a card sorting bracket 20, a card suction wheel 30, a separation mechanism 50 and a card delivery wheel 60.

[0049] In this embodiment, the card loading bracket 10 is fixedly arranged inside the mahjong machine, and the card suction wheel 30 is installed on the card loading bracket 10. Among them, the card suction wheel 30 can rotate around its own axis. Figure 3 , Figure 4 As shown, three card-absorbing planes 31 are evenly distributed in the circumferential direction of the card-absorbing wheel 30, and card-absorbing magnets are installed inside the card-absorbing planes 31 for absorbing mahjong tiles from the shuffling plate of the mahjong machine and transporting the absorbed mahjong tiles upward through the rotation of the card-absorbing wheel.

[0050] It should be noted that the structure of the card-absorbing wheel 30 is an existing conventional structure. In this embodiment, it has three card-absorbing planes 31. There are also card-absorbing wheels with other numbers of card-absorbing planes in the prior art, such as four card-absorbing planes.

[0051] In this embodiment, Figure 1 , Figure 5 As shown, a card discharging channel 11 is formed between the card loading bracket 10 and the card sorting bracket 20 which are arranged relatively, wherein the card discharging side of the card suction wheel is located in the card discharging channel, and the width of the card discharging channel 11 is adapted to the width of the mahjong after the cards are sorted, and is used to control the discharging direction of the mahjong tiles. It should be noted that the mahjong width here is a relative concept, and the length of the mahjong tiles along the direction of conveying the mahjong tiles is set as the mahjong length. Then the mahjong length can be either the actual length of the mahjong tiles or the actual width of the mahjong tiles.

[0052] In this embodiment, the length of the mahjong along the direction of mahjong transportation is the actual length of the mahjong, and the width of the card-discharging passage 11 is adapted to the actual width of the mahjong. Figure 1 , Figure 3 As shown, since the mahjong tiles 12 are adsorbed on the card suction plane from the shuffling plate, their adsorption direction is random. During the upward rotation of the card suction wheel, after passing through the card sorting plate 21 on the card sorting bracket 20, the horizontally placed mahjong tiles or mahjong tiles with irregular directions are sorted and guided by the card sorting plate 21 and enter the card outlet channel in a consistent direction.

[0053] In this embodiment, the separation mechanism 50 is installed in the card discharging channel and adjacent to the card suction wheel 30. The separation mechanism is fixedly installed on the card loading bracket or between the card loading bracket and the card sorting bracket, wherein the meaning of adjacent can be understood as being adjacent and close, but with a small gap, and not in direct contact. The side of the separation mechanism 50 close to the card suction wheel is provided with a first inner arc 54 adapted to the outer circumference of the card suction wheel. The diameter of the first inner arc is slightly larger than the diameter of the card suction wheel, so that the upper surface of the separation mechanism close to the card suction wheel is close to the card suction wheel but does not contact the card suction wheel. In this way, the separation mechanism does not affect the normal rotation of the card suction wheel, and cannot allow the mahjong cards adsorbed on the card suction plane to pass through. When the adsorbed mahjong cards rotate to the separation mechanism, they are separated by the separation mechanism and transported to the upper surface of the separation mechanism. Among them, the height of one end of the upper surface of the separation mechanism close to the card suction wheel must be lower than the highest position of the card suction plane on the card suction wheel. In this way, when the mahjong tiles adsorbed on the card suction plane continue to rotate downward after passing the highest point, since there is no space between the end of the upper surface of the separation mechanism close to the card suction wheel and the card suction wheel to accommodate the passage of the mahjong tiles, one end of the mahjong tiles is separated and enters the upper surface of the separation mechanism. Under the rotation of the card suction wheel, the mahjong tiles are pushed to move on the upper surface of the separation mechanism to the side away from the card suction wheel.

[0054] In this embodiment, a card delivery wheel 60 is installed adjacent to the side of the separation mechanism 50 away from the card suction wheel. The card delivery wheel 60 is configured with a second driving device for driving the card delivery wheel to rotate. The card delivery wheel is located in the card output channel near the exit. In this embodiment, one end of the card delivery wheel is rotatably connected to the card loading bracket, and the other end is rotatably connected to the card sorting bracket. It should be noted that the rotatable connection is a conventional connection method in this field, and a bearing or a rotating shaft is usually used to achieve a high-precision rotatable connection.

[0055] In this embodiment, the mahjong tiles on the upper surface of the separation mechanism are pushed by the card suction wheel, and the lower surface of one end of the mahjong tiles contacts the surface of the card delivery wheel. The rotating card delivery wheel then applies a continuous driving force to the mahjong tiles, and the mahjong tiles on the upper surface of the separation mechanism are transported to the stacking mechanism.

[0056] In the present structure, since the card feeding wheel is provided with an independent second driving device, the card feeding wheel directly acts on the mahjong tiles through a continuous driving force and transports the mahjong tiles to the stacking mechanism, rather than relying on the mahjong tiles' own gravity to fall to the stacking mechanism. In this way, the mahjong tiles can smoothly leave the separation mechanism and enter the stacking mechanism, and since the driving force they receive is continuous and stable, the time for all mahjong tiles to leave the separation mechanism and enter the stacking mechanism is basically the same. In this way, the control difficulty is reduced for the coordination between the various mechanisms of the automatic mahjong machine, and the failure rate of the system will also be greatly reduced.

[0057] As a preferred implementation of this embodiment, the upper surface of the separation mechanism 50 is configured to have a certain length in the conveying direction of the mahjong tiles, and the certain length does not exceed the length of the mahjong tiles themselves in the conveying direction, and is preferably a length close to half the length of the mahjong tiles to a length close to the length of the mahjong tiles. Usually, the certain length is less than the length of the mahjong tiles, but its length accounts for a large proportion of the length of the mahjong tiles, so that the mahjong tiles can more stably control the card-discharging posture of the mahjong tiles on the upper surface of its separation mechanism, improve the consistency and reliability of the smooth card-discharging of the mahjong tiles, thereby reducing the failure rate. At the same time, since the length of the upper surface of the separation mechanism along the conveying direction does not exceed the length of the mahjong tiles themselves in the conveying direction, the conveying driving force of the mahjong tiles between the card suction wheel and the card delivery wheel can be effectively connected, avoiding the interruption of the conveying driving force, thereby ensuring the reliability of the mahjong tiles entering the stacking mechanism smoothly and the stability of the system operation.

[0058] As another preferred implementation of this embodiment, Figure 4 As shown, the upper surface of the separation mechanism 50 is configured to have a high position 51, and the upper surface of the separation mechanism forms an inclined surface 52 that gradually decreases from the high position 51 to the card delivery wheel. The purpose of such a setting is that the mahjong tiles can be transported to contact with the card delivery wheel more smoothly and with less resistance, so that the mahjong tiles are delivered by the driving force provided by the card delivery wheel. In this embodiment, the plane 53 between the high position 51 and the card suction wheel can be in a horizontal state, or it can be an inclined surface that gradually decreases from the high position to the card suction wheel.

[0059] Of course, the above structure is only a preferred implementation of this embodiment, and is not the only limitation thereof. The upper surface of the separation mechanism can be a horizontal surface or an inclined surface that gradually decreases from the card suction wheel side to the card delivery wheel side.

[0060] It should be noted that the highest position of the card feeding wheel is substantially consistent with the height of the end of the upper surface of the adjacent separation mechanism, thus ensuring that the mahjong tiles can be smoothly transported from the upper surface of the separation mechanism to contact the card feeding wheel.

[0061] As another preferred implementation of this embodiment, Figure 2-4 As shown, in this embodiment, the second driving device for driving the card delivery wheel 50 to rotate and the first driving device for driving the card suction wheel to rotate are driven by the same driving device. In this embodiment, the driving device is a motor 40. The advantages of such a setting are that it has the advantages of high system integration, high utilization of the driving device and cost saving. At the same time, fewer driving devices are of great significance for reducing the failure rate.

[0062] Specifically, the motor 40 is installed on the back side of the card-loading bracket 10, and the motor 40 is coaxial with the card-absorbing wheel 30. The output shaft 41 of the motor is connected to the card-absorbing wheel through a coupling 42.

[0063] In this embodiment, a preferred transmission mechanism, such as Figure 2-4 As shown, it includes a first gear 70 coaxially connected to the card suction wheel, a second gear 71 coaxially connected to the card delivery wheel, and an intermediate gear 72 respectively meshed with the first gear and the second gear. When the motor 40 drives the card suction wheel to rotate, it synchronously drives the first gear 70 to rotate, and the first gear then drives the intermediate gear 72 meshed with it to rotate, and then the intermediate gear drives the second gear meshed with it to rotate, and then drives the card delivery wheel to rotate through the second gear, thereby realizing the continuous rotation drive of the card delivery wheel, and at the same time realizing that the card delivery wheel and the card suction wheel share the motor 40.

[0064] Embodiment 2

[0065] The present embodiment discloses a license plate device, the structure of which is as follows: Fig. 9 As shown, the main difference from the first embodiment is that an auxiliary card feeding wheel 61 parallel to the card feeding wheel 60 is provided in the area of ​​the separation mechanism 50 for accommodating the passage of mahjong tiles, and a rotating shaft is provided at both ends of the auxiliary card feeding wheel 61 so that the auxiliary card feeding wheel 61 can rotate around its own axis.

[0066] The biggest difference between this embodiment and the first embodiment is that the sliding friction between the mahjong tiles and the upper surface of the separation mechanism is changed to rolling friction, so that the mahjong tiles are more efficient and more stable. After one end of the mahjong tiles is separated from the card suction wheel and contacts the upper surface of the separation mechanism, the card suction wheel continues to rotate, pushing the mahjong tiles to move toward the position of the card delivery wheel on the separation mechanism. In this process, after the mahjong tiles contact the auxiliary card delivery wheel, the auxiliary card delivery wheel rotates under the push of the card suction wheel, and the rolling friction between the mahjong tiles and the separation mechanism is very small, which also reduces the wear between the mahjong tiles and the separation mechanism, further improving the service life of the mahjong tiles and the separation mechanism.

[0067] When one end of the mahjong tile is pushed to contact the card feeding wheel, the card feeding wheel actively rotates to drive the mahjong tile to move toward the stacking mechanism.

[0068] Embodiment 3

[0069] The embodiment discloses a license plate device, the structure of which is as follows Fig. 9 , Fig.10 As shown, the main difference from the first embodiment is that an auxiliary card feeding wheel 61 is provided in the area of ​​the separation mechanism 50 for accommodating mahjong tiles, and a rotating shaft is provided at both ends of the auxiliary card feeding wheel 61 so that the auxiliary card feeding wheel 61 can rotate around its own axis.

[0070] The main difference between this embodiment and the second embodiment is that in the second embodiment, the auxiliary card delivery wheel is passively rotated, while in this embodiment, the auxiliary card delivery wheel and the card delivery wheel are synchronously and actively rotated. Fig.10As shown, it also includes a third gear 73 coaxially connected to the auxiliary card feeding wheel, and the third gear 73 meshes with the middle gear 72. At the same time, the card feeding wheel meshes with the middle gear through the second gear 71, and the specifications of the second gear and the third gear are consistent, ensuring that the card feeding wheel and the auxiliary card feeding wheel rotate synchronously.

[0071] In this embodiment, the auxiliary card feeding wheel is set as an active rotating structure, the purpose is to further ensure the stability and reliability of the card loading device. Since the mahjong tiles and the card suction wheel are magnetically matched, when one end of the mahjong tiles is separated from the card suction wheel, the magnetic force of the card suction wheel is used to push the mahjong tiles to move a long distance, which has certain risks. Sometimes, the card suction plane separated from the mahjong tiles fails to push the mahjong tiles into place, and the card suction plane at the next position needs to rotate over to push the mahjong tiles again, thus delaying the efficiency of card loading.

[0072] In the present embodiment, since the auxiliary card feeding wheel is actively moving, the mahjong tiles will contact the auxiliary card feeding wheel after moving a short distance after being separated. After that, the movement of the mahjong tiles will not only rely on the push of the card suction wheel, but will mainly move toward the card feeding wheel driven by the auxiliary card feeding wheel, thus ensuring the stability and efficiency of loading the mahjong tiles.

[0073] Embodiment 4

[0074] The present embodiment discloses a license plate device, the structure of which is as follows: Figure 11-13 As shown, the main difference from the first embodiment is that an auxiliary card feeding wheel 61 parallel to the card feeding wheel 60 is provided in the area of ​​the separation mechanism 50 for accommodating the passage of mahjong tiles, and a rotating shaft is provided at both ends of the auxiliary card feeding wheel 61 so that the auxiliary card feeding wheel 61 can rotate around its own axis.

[0075] Furthermore, in this embodiment, a synchronous belt 62 is provided between the card feeding wheel and the auxiliary card feeding wheel, wherein the functions of the synchronous belt 62 are, firstly, to drive the auxiliary card feeding wheel to rotate synchronously by the card feeding wheel; secondly, to provide a plane for the movement of mahjong cards.

[0076] In this embodiment, after one end of the mahjong tiles is separated from the card suction wheel by the separation mechanism, it runs a very small distance and then enters the upper surface of the synchronous belt. After that, the mahjong tiles will be actively transported to the position of the stacking mechanism by the synchronous belt, and do not rely on the magnetic force of the card suction wheel, making the card loading more stable and efficient.

[0077] Embodiment 5

[0078] This embodiment discloses a mahjong machine, wherein the card loading device adopts the card loading device disclosed in any one of the embodiments 1 to 4. In this embodiment, the four groups of card loading devices are respectively arranged on the four sides of the mahjong machine, and each group of card loading devices is correspondingly provided with a stacking mechanism, and the stacking seat 13 of the stacking mechanism is located at the exit side of the card output channel and adjacent to the card delivery wheel, wherein the stacking seat can be raised and lowered. It should be noted that the stacking mechanism adopts an existing conventional structure, which will not be described in detail here.

[0079] Embodiment 6

[0080] The card loading method of the mahjong machine disclosed in this embodiment is a card loading method for the mahjong machine shown in the fifth embodiment using the card loading device shown in the first embodiment, and the card loading method includes a card suction and conveying step, a separation step and a card delivery step.

[0081] Among them, in the card suction and transportation step, the card suction wheel absorbs the mahjong tiles in the shuffled plate onto the card suction plane on the card suction wheel and transports the mahjong tiles upward through the rotation of the card suction wheel.

[0082] Among them, in the separation step, the separation mechanism separates the mahjong tiles adsorbed on the card suction wheel. Under the push of the card suction wheel, the separated mahjong tiles move from the side of the separation mechanism close to the card suction wheel along the upper surface of the separation mechanism to the side of the card feeding wheel.

[0083] Among them, in the card feeding step, the card suction wheel pushes the separated mahjong tiles to the side of the mahjong tiles close to the card feeding wheel and contacts the card feeding wheel, and then the mahjong tiles are transported to the stacking seat of the stacking mechanism through the rotation of the card feeding wheel.

[0084] The card loading method of this embodiment delivers the mahjong tiles through the active driving force of the card delivery wheel, so that the force direction of the delivered mahjong tiles is uniform, the consistency of the card delivery posture is very high, and the failure rate is very low in the application of automatic mahjong machines.

[0085] Preferably, in this embodiment, when the mahjong machine shown in Example 5 adopts the card loading device shown in Example 2, in the card feeding step, after the card suction wheel pushes the mahjong cards to contact with the auxiliary card feeding wheel, there is rolling friction between the mahjong cards and the auxiliary card feeding wheel, with a small contact area, smaller friction and wear, and the mahjong cards continue to be pushed until they contact with the card feeding wheel, and then the mahjong cards are transported to the stacking seat of the stacking mechanism through the rotation of the card feeding wheel.

[0086] Preferably, in this embodiment, when the mahjong machine shown in the fifth embodiment adopts the card loading device shown in the third embodiment, in the card feeding step, the card suction wheel pushes the mahjong cards to contact with the auxiliary card feeding wheel, and then the auxiliary card feeding wheel actively rotates to send the mahjong cards to contact with the card feeding wheel, and then the mahjong cards are continued to be transported to the stacking seat of the stacking mechanism through the rotation of the card feeding wheel.

[0087] Preferably, in this embodiment, when the mahjong machine shown in the fifth embodiment adopts the card loading device shown in the fourth embodiment, in the card feeding step, the card suction wheel pushes the mahjong cards until they come into contact with the synchronous belt, and then the synchronous belt transports the mahjong cards to the stacking seat of the stacking mechanism.

[0088] In this embodiment, as a preference, a counting step and a position sensing step are also included.

[0089] like Figure 6-8 As shown, in this embodiment, a control panel 80 is provided on the back side of the card loading bracket 10 at a position corresponding to the card discharging passage, and a counting sensor 81 and a Hall induction sensor 82 are provided on the control panel 80. Correspondingly, a light hole 83 is provided at a position corresponding to the counting sensor 81 on the card loading bracket, and an induction magnet 84 corresponding to the card suction plane is provided on the back side of the card suction wheel, and the induction magnet 84 is used to cooperate with the Hall induction sensor 82 to sense the position of the mahjong tiles. Among them, the counting sensor 81 and the light hole 83 are provided at a position corresponding to the card feeding wheel or the separation mechanism.

[0090] In the position sensing step of this embodiment, during the rotation of the card suction wheel, when one of the sensing magnets rotates to a position corresponding to the Hall sensor, a signal is sent to the control system corresponding to the control panel, and a signal is sent to the counting sensor.

[0091] In the counting step of this embodiment, after the technical sensor receives the signal sent in the position sensing step, the counting sensor reads and counts the signals of the mahjong tiles passing through the light hole position.

[0092] Through the coordination of the position sensing step and the counting step, the card suction wheel is controlled to continue to run or stop, thereby realizing the operation of putting mahjong tiles. It should be noted that the coordination of the position sensing step and the counting step will also control the action of the stacking mechanism, which will not be described in detail here.

[0093] In short, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
