Description

Technical Field

[0001] The present invention relates to the field of poker machines, in particular to a poker machine and a card dealer thereof. Background Art

[0002] Playing cards are a popular entertainment item. After playing a round of cards, players need to sort, shuffle and deal the cards themselves. In order to save time in dealing cards, people have invented automatic card dealing machines to deal cards. For example, a patent document with publication number CN201164714Y discloses a four-mouth playing card dealing machine, which has a shuffling chamber, a shuffling differential driven by a shuffling motor is installed in the center of the shuffling chamber, and four conveyor belts connected to the card dealing mechanism are evenly distributed around it. The conveyor belts are driven by a conveying motor, and a card handling wheel is installed on one side of each conveyor belt, and a block matched with the card handling wheel is installed on the other side. The card handling wheel is installed with a spiral lever, and a counting photoeye is installed at the output end of the card dealing mechanism. When the card dealing machine is in use, the messy cards are placed face down in the shuffling chamber, and the cards are sent out from four outlets after passing through the shuffling differential, the card handling wheel and the card dealing mechanism. Although the card dealing machine basically completes the actions of shuffling and dealing cards, it still cannot avoid the need for players to collect, sort, and flip the playing cards with the front and back facing different directions, resulting in high labor intensity and long waiting time during the game.

[0003] A fully automatic poker machine is disclosed in the patent document with publication number CN102580307A, which includes a mounting base plate and a plurality of supporting legs arranged at the bottom of the mounting base plate; a card inlet for placing playing cards is arranged on the mounting base plate and is opened in a manner parallel to the table top; a shuffling and primary card separation device is arranged at one end of the card inlet and is used for initially separating disordered playing cards; a straight card and secondary card separation device is arranged at the other end of the shuffling and primary card separation device and is used for adjusting the playing cards to the same direction and separating them into single cards; a card flipping and card dealing device is arranged at the other end of the straight card and secondary card dealing device and is used for adjusting single playing cards with different front and back sides to the same direction and dealing the cards according to regulations; a card pushing device is arranged at the other end of the card flipping and card dealing device and is used for moving the dealt playing cards; and a card raising device is arranged at one side of the card pushing device and is used for raising the playing cards onto the table top. Among them, the shuffling and initial card dealing equipment realizes initial card dealing (separating the playing cards into a few cards) through the different rotation speeds of the card feeding belt and the card dealing belt; the straight and secondary card dealing equipment transports the playing cards through the secondary card dealing belt and realizes straight dealing (adjusting the playing cards to the same direction, i.e. sorting the cards) through the straight belt and the auxiliary straight belt on both sides; the card flipping equipment realizes card flipping (turning the playing cards to the required side) through the cooperation of the card flipping plate and three concave card flipping belts; the card dealing equipment realizes random card dealing (i.e. shuffling and dealing) through the cooperation of the card dealing belt and the card dealing rod; the dealt playing cards fall directly on the card pushing panel and then are pushed to the card raising panel by the card pushing rod, and the card raising equipment raises the playing cards onto the table top.

[0004] Although the above-mentioned poker machine basically realizes the actions of arranging, shuffling and dealing the poker cards, it still has the following problems due to its structural limitation:

[0005] 1. The gap between the conveyor belt and the surrounding wall is easy for playing cards to be embedded, which can easily cause the playing cards to be damaged, missing, stuck or equipment failure;

[0006] 2. The playing cards are placed flat on the conveyor belt, and the playing cards are rotated and adjusted in the horizontal plane by the opposite movement of the belts on both sides, so as to achieve the purpose of horizontal card sorting. This can easily cause the playing cards to float, get stuck between the belts on both sides, or even be damaged or embedded in the gap between the belts. In addition, the conveying speed and length of the conveyor belt have high requirements, resulting in low card sorting efficiency.

[0007] 3. The card flipping is realized by using a card flipping plate and three card flipping belts, which has the disadvantages of unstable card flipping and low card flipping efficiency, and there is also the disadvantage of playing cards getting stuck in the gap between the belts;

[0008] 4. The use of a card-dealing belt and multiple card-dealing ports arranged in a straight line has the disadvantages of unstable card dealing and low efficiency. In addition, the playing cards in multiple positions are raised in the same position, which makes it inconvenient for players to take cards and also poses the possibility of cheating.

[0009] The patent document with the publication number CN103055499A discloses a fully automatic poker machine, comprising: a card feed frame for placing playing cards, a card feeding mechanism for conveying playing cards is provided at the bottom of the card feed frame; a card sorting slot for vertically placing playing cards, the card sorting slot is provided with at least two card sorting components capable of relative movement so as to move playing cards so as to move them out of the card sorting slot in a manner of vertical length; a vertical card transfer device for vertically placing playing cards sent from the card feed frame in the card sorting slot; a card flipping device for flipping the front and back sides of playing cards, the card flipping device is installed at the exit side of the card sorting slot; a card dealing device installed behind the card flipping device for randomly sending playing cards to a plurality of receiving boxes; and a plurality of card lifting devices for respectively lifting playing cards in each receiving box onto the table. The poker machine uses ordinary playing cards and adopts a vertical card sorting method, which greatly improves the accuracy and efficiency of card sorting. However, the poker machine has many parts and devices, and the manufacturing cost is high.

[0010] The patent document with publication number CN105854274A discloses a poker machine and a poker card sorting method thereof, which eliminates the card sorting device and the vertical card transfer device, and sets a card dispensing mechanism at the card outlet of the existing card inlet frame, and the card dispensing mechanism sends a single poker card into the card flipping device for flipping and dealing. The poker cards that have been sorted into a pile can be separated, flipped, shuffled and dealt, and the shuffling efficiency is high, the reliability is good, and the machine manufacturing cost is low. However, the card flipping device of the poker machine can only send one mahjong tile to the card flipping box at a time for identification, flipping and sending out the dealing card, and the card flipping efficiency is low, and the card flipping box has a large rotation noise, a large motor load, a complex structure, and poor stability.

[0078] like Fig. 20 , Fig.21 As shown, the card pushing driving mechanism is arranged under the card receiving seat 2, including a card pushing motor 201, a card pushing driving member 206 and a plurality of card pushing swing arms 207 corresponding to the plurality of card pushing plates 202 one by one. The card pushing driving member 206 is in a circular shape, and the card pushing driving member 206 is installed at the bottom of the card receiving seat 2 through a plurality of positioning rollers B208 and is driven to rotate by the card pushing motor 201. A plurality of driving parts corresponding to the plurality of card pushing swing arms 207 are extended from the outer circumference of the card pushing driving member 206, and one driving part is connected to one card pushing plate 202. The middle part of the card swing arm 207 is movably connected through the chute A2071, one end of the card pushing swing arm 207 is movably connected (hinged) with the bottom of the card receiving seat 2, and the other end of the card pushing swing arm 207 is movably connected with the bottom of the card pushing plate 202 through the chute B2072 and the card pushing roller 2021, so that each card pushing swing arm 207 is driven to rotate by rotating the card pushing driving member 206, and then the card pushing plate 202 is driven to do a card pushing action from the inside of the card receiving position to the outside or to do a reset action from the outside of the card receiving position to the inside. Such a card pushing driving member synchronously drives multiple card pushing plates, which has simple structure, reasonable action, reliable operation and low manufacturing cost. The card pushing swing arm 207 is in the shape of a V-shaped boomerang. The card pushing motor 201 drives the card pushing driving member 206 to rotate through the gear and gear ring matching structure, or the card pushing motor 201 drives the card pushing driving member 206 to rotate through the card pushing cam 2011 and the chute 2061 matching structure.

[0079] like Figure 3 , Figure 6 As shown, the lifting drive mechanism includes a lifting drive member 5, a lifting motor 501 and multiple lifting swing arms 503. The multiple lifting swing arms 503 are evenly distributed below the card receiving seat 2 of the movement. One end 5031 of the lifting swing arm 503 is hinged to the base 1, and the other end 5033 of the lifting swing arm 503 is against the bottom of the card receiving seat 2 of the movement. The lifting swing arms 503 are driven by the lifting motor 501 through the lifting drive member 5 to swing synchronously, thereby pushing the movement to lift. In this embodiment, the lifting drive member 5 is in a circular ring shape, and a plurality of lifting protrusions 502 corresponding to the plurality of lifting swing arms 503 are arranged on the top of the ring. The lifting protrusions 502 are against the middle support rollers 5032 of the lifting swing arms 503. The lifting drive member 5 is installed on the base 1 through the support rollers 101 and the positioning rollers 102 and can rotate around the rotation center. In this embodiment, the plurality of support rollers 101 are arranged on the outer side of the ring of the lifting drive member, and the lifting drive member is provided with grooves matching with the grooves so as to limit the rotation range of the lifting drive member 5. The plurality of positioning rollers 102 are installed on the inner side of the circular ring of the lifting drive member 5 so as to achieve the function of positioning the rotation center of the lifting drive member; when the lifting drive member 5 rotates under the drive of the lifting motor 501, the middle supporting rollers 5032 on the plurality of lifting swing arms 503 respectively move along the corresponding lifting protrusions 502 on the lifting drive member 5, so that the lifting protrusions 502 push the lifting swing arms 503 to swing, so as to achieve the function of lifting and lowering the end 5033 of the lifting swing arm 503 against the bottom of the movement, that is, to achieve the effect of lifting the movement. Fig. 22 , Fig.23 As shown, in this embodiment, the lifting motor 501 is installed on the base 1 through the lifting motor bracket 504, and a horizontally rotating lifting cam 505 is installed on the output shaft of the lifting motor 501 (or the output shaft of the reduction mechanism connected to the lifting motor), and the lifting cam 505 slides with the lifting groove 506 on the lifting drive member 5 through the roller to drive the lifting drive member 5 to rotate. In other embodiments, the lifting motor can also drive the lifting drive member to rotate by the internal or external meshing of the driving gear and the gear ring.

[0080] like Figure 4 , Figure 5 , Figure 7 , Figure 8 As shown, the card issuing device is fixed on the card issuing seat 4, and the card issuing seat 4 is rotatably mounted at the center position of the upper part of the card receiving seat 2 through a bearing and driven to rotate by a rotary driving mechanism, as shown in FIG. Figure 5 , Fig. 9 As shown, the rotary drive mechanism includes a rotary motor 203 installed at the bottom of the card receiving seat 2 and a driven wheel 209 that is fixed and rotates synchronously with the card issuing seat 4 in the circumferential direction. The rotary motor 203 drives the driven wheel 209 through a rotating transmission belt 205, thereby driving the card issuing seat 4 to rotate.

[0081] like Figures 9 to 15 As shown, the card dealer includes a card storage box 41 and a card dealing device 42, which are respectively located on the left and right sides of the card dealing seat 4, and one side of the bottom of the card storage box 41 is connected to the card feeding channel of the card dealing device 42. The card storage box 41 is provided with a card feeding wheel 4201 for pushing the playing cards to the card feeding channel of the card dealing device 42. A card baffle plate 4105 is formed on one side wall of the card storage box 41 close to the card feeding channel of the card dealing device 42. A plurality of card feeding ridges 4104 are provided on the card baffle plate 4105. A card dividing wheel 4202 of the card dealing device 42 is arranged below the card feeding ridges 4104. A plurality of card feeding protrusions 4102 are formed on the inner wall of the bottom of the card storage box 41 between the card feeding wheel 4201 and the card dividing wheel 4202. Thus, a card feeding channel 4103 of the card dealing device 42 is formed between these card feeding protrusions 4102 and the card feeding protrusions 4104. Such a concave and convex matched card feeding channel helps to squeeze and separate multiple overlapping playing cards. Further preferably, a plurality of card-feeding protrusions 4102 and a plurality of card-feeding ridges 4104 are alternately arranged to obtain a better card-shuffling and card-separating effect.

[0082] The card dealing device 42 includes a card dividing mechanism, a conveying mechanism and a card flipping mechanism. The channels for the passage of playing cards in the card dealing device 42 include a card input channel 4103, a conveying channel, a card flipping channel 4224, a first card output channel 4208 and a second card output channel 4213. A card flipping component 4209 for opening or closing the card flipping channel 4224 or the exit of the first card output channel 4208 is arranged near the first card output channel 4208. When the card flipping component 4209 closes the card flipping channel 4224 or opens the exit of the first card output channel 4208, the card input channel 4103, the conveying channel and the first card output channel 4208 are connected in sequence. When the card flipping component 4209 opens the card flipping channel 4224 and closes the exit of the first card output channel 4208, the card input channel 4103, the conveying channel, the first card output channel 4208, the card flipping channel 4224 and the second card output channel 4213 are connected in sequence. The card separating mechanism is installed at the card input channel of the card dealing device 42 , the conveying mechanism is installed at the conveying channel position, and the card flipping mechanism is installed between the first card output channel 4208 and the second card output channel 4213 .

[0083] The card separation mechanism can adopt various card separation structures disclosed in a series of patent documents such as CN108525278A and CN105854274A. However, although these card separation structures can better separate the incoming playing cards to ensure that a single card passes through, it is difficult to allow the playing cards that have entered the conveying channel to exit (retract) from the card entry channel. In this way, once the subsequent sensor detects that two playing cards overlap and needs to withdraw the playing cards and notify the card delivery for re-separation, the problem of difficulty in retracting the cards occurs. In order to overcome this technical problem, in this embodiment, the card separation mechanism preferably has the following structure:

[0084] like Figures 9 to 12 As shown, it includes a card baffle plate 4105, a card delivery wheel 4201, a card separation wheel 4202 and a card separation pressure wheel 4222. The card delivery wheel 4201 for pushing playing cards to the card feeding channel of the card issuing device 42 is installed at the bottom of the card storage box 41, the card separation pressure wheel 4222 is arranged at the bottom of the card baffle plate 4105, and the card separation pressure wheel 4202 is arranged below the card separation pressure wheel 4222. The card separation wheel 4202 is driven to rotate by the card issuing motor, and the card separation pressure wheel 4222 can rotate when the card is not rotated when the card is input and can rotate when the card is withdrawn through a one-way clutch mechanism. In this way, not only can a fast and effective card separation function be achieved when the card is input, but also when the card needs to be withdrawn, the card separation pressure wheel 4222 can cooperate with the card separation wheel 4202 to reverse together to achieve fast and reliable card withdrawal, thereby avoiding the difficulty of withdrawing the card. The card dividing pressing wheel 4222 and the card dividing wheel 4202 are further preferably designed to be staggered front and back and overlapped up and down (i.e., the card dividing pressing wheel 4222 and the axis of the card dividing wheel 4202 are staggered by a horizontal distance and the card dividing pressing wheel 4222 is closer to the card storage space of the card storage box 41 than the axis of the card dividing wheel 4202, and the bottom of the card dividing pressing wheel 4222 is lower than the highest point of the card dividing wheel 4202). In this way, when a plurality of playing cards enter the gap between the card dividing pressing wheel 4222 and the card dividing wheel 4202, the entering end of the playing cards will be tilted so that the upper and lower playing cards will be displaced from This avoids the upper and lower playing cards from being electrostatically adhered and unable to be separated, because the card separating pressure wheel 4222 is controlled by the one-way clutch mechanism and cannot rotate, so the static friction between the card separating pressure wheel 4222 and the upper playing cards is much greater than the friction between the upper and lower playing cards, and the conveying power of the playing cards comes from the card separating wheel 4202, which is applied to the lower playing cards. Therefore, the lower playing cards are conveyed and continue to move forward, and the upper playing cards are temporarily detained, and the upper and lower playing cards are separated. The separation speed is fast, the structure is simple, the maintenance is convenient, and the accuracy is high.

[0085] In order to further enhance the card-splitting effect of the above-mentioned card-splitting mechanism, a plurality of card-feeding ridges 4104 are provided at the bottom of the card-blocking plate 4105, and a plurality of card-feeding protrusions 4102 are formed on the inner wall at the bottom of the card storage box 41 between the card-delivering wheel 4201 and the card-splitting wheel 4202. The card-feeding ridges 4104 are closer to the card-splitting pressure wheel 4222 than the card-feeding ridges 4102. In this way, a card-feeding channel 4103 of the card-delivering device 42 is formed between the card-feeding ridges 4102, the card-feeding ridges 4104 and the card-splitting wheel 4202. The protrusion 4102 and the card-splitting wheel 4202) tilt up the sunken structure in the middle, so that the concave-convex matching card-entering channel helps to squeeze and rub the overlapping multiple playing cards to separate them, ensuring that the multiple playing cards entering the positions of the card-splitting wheel 4202 and the card-splitting pressure wheel 4222 are separated front and back. In addition, because the card-entering protrusion 4102 will lift the playing cards in the card storage box 41 outside the card-entering channel 4103, when the cards are withdrawn, the playing cards withdrawn from the card-entering channel will be inserted under the playing cards in the card storage box 41, avoiding the two playing cards from being offset and causing difficulty in pushing the cards. Further preferably, multiple card-entering protrusions 4102 and multiple card-entering ridges 4104 are alternately arranged to obtain a better card-rubbing and separation effect.

[0086] In this embodiment, one side of the card feeding wheel 4201 is protruded to form an arc-shaped sawtooth, so that the playing cards can be pushed upward and forward during the rotation of the card feeding wheel 4201, so that the playing cards can better cross the card feeding protrusion 4102. In addition, this action can also prevent the front and rear playing cards from being stuck when the card issuing device withdraws the cards. The card separation pressure wheel 4222 passively rotates in one direction. In order to facilitate adjustment, the card separation pressure wheel 4222 is installed at the bottom of the card baffle plate 4105 through an elastic pressure mechanism. The elastic pressure mechanism is a compression spring and a push rod 4221, and the one-way clutch mechanism is a one-way clutch installed on the shaft of the card separation pressure wheel 4222. Each of the components of the card separation wheel, the card feeding wheel and the card separation pressure wheel can be a roller part, or it can be composed of multiple wheel-shaped parts installed on the same shaft, for example, Fig.16 , Fig.17As shown, each card-distributing wheel 4202 comprises a support frame with a certain rigidity and a rubber ring sleeved and fixed on the support frame, a part of the arc-shaped circumference of the rubber ring is a protruding arc-shaped rubber sawtooth for contacting with playing cards, and a part of the circumference of the rubber ring other than the arc-shaped rubber sawtooth is lower than the side wall circumference of the support frame, so that when the arc-shaped rubber sawtooth part of the card-distributing wheel contacts with the playing cards, the friction force is large, so it is easier to drive the playing cards to move, and when the side wall circumference of the support frame of the card-distributing wheel contacts with the playing cards, the friction force is small, so it is difficult to drive the playing cards to move, and the gap-type driving of the playing cards to move helps to separate two playing cards. Four card-distributing wheels 4202 are installed on the same card-distributing wheel shaft 42021, and the card-feeding convex edge 4104 and the card-distributing pressure wheel 4222 at the bottom of the baffle plate 4105 are arranged alternately and staggered with the four card-distributing wheels 4202, so that it is easy to adjust the upper and lower gaps to achieve fast and effective card distribution. The card delivering wheel shaft 42011 of the card delivering wheel 4201 and the card separating wheel shaft 42021 of the card separating wheel 4202 are connected by a card feeding transmission belt 4228, so that the card delivering wheel 4201 and the card separating wheel 4202 can rotate in coordination to improve the card separating efficiency and effect.

[0087] like Figures 9 to 12 As shown, the conveying mechanism includes a first conveying wheel 4203 and a second conveying wheel 4205 installed on a conveying bottom wall 4204 of the conveying channel, and a first conveying pressure wheel 4219 and a second conveying pressure wheel 4217 installed on a conveying top wall 4218 of the conveying channel. The first conveying pressure wheel 4219 cooperates with the first conveying wheel 4203 up and down, and the second conveying pressure wheel 4217 cooperates with the second conveying wheel 4205 up and down. The first conveying pressure wheel 4219 and the second conveying pressure wheel 4217 are driven wheels. The wheel 4203 and the second conveying wheel 4205 are driving wheels and are sleeved with rubber rings to increase friction. The first conveying wheel shaft 42031 of the first conveying wheel 4203, the second conveying wheel shaft 42051 of the second conveying wheel 4205, the card-distributing wheel shaft 42021 of the card-distributing wheel 4202 and the card-distributing motor shaft 42201 of the card-distributing motor 4220 are connected by a card-distributing transmission belt 4225, and the card-distributing transmission belt 4225 is tensioned by a tensioning wheel 4226, so that the synchronous movement of card-feeding, card-distributing and conveying is realized. The first conveying wheel 4203, the second conveying wheel 4205, the first conveying pressing wheel 4219 and the second conveying pressing wheel 4217 can be directly pressed and matched up and down, or staggered and staggered matched up and down, and each component can be a roller part, or can be composed of a plurality of wheel-shaped parts installed on the same shaft.

[0088] like Fig.13 , Fig.19 As shown, an identification element for identifying the front and back sides of playing cards and a plurality of detection elements for detecting playing cards are provided in the conveying channel of the above-mentioned card distributor.

[0089] Regarding identifying the front and back of playing cards in the conveying channel: one method is to obtain photo information of different positions on the same side of the playing cards, and use the rule that the pattern on the back of the playing cards is a unit pattern with a high degree of overlap in four consecutive positions to determine whether it is the front or back of the playing card based on the degree of overlap of the graphics of these photos. Another method is to identify the front and back of the playing card by distinguishing the character patterns at the fixed positions at the diagonal angles of the front of the playing card, based on the characteristic that characters must be set at the fixed positions at the diagonal angles of the front of the playing card, such as the master's thesis entitled "Research on the Application of Image Recognition in Card Dealing Machines" published by Kou Yongjun in the journal of Hunan University in 2007. Another method is to print magnetic ink at a fixed position on the front or back of the playing card, and identify the front and back of the playing card by detecting the magnetic ink. For the first two identification methods, the identification element is a camera. For the third identification method, the identification element is a magnetic detection sensor.

[0090] Regarding identifying whether there is overlap of playing cards in the conveying channel: one method is to detect the length of playing cards. When the detection element detects that the length of playing cards in the conveying channel is longer than the normal length, it can be determined that there are multiple playing cards overlapping. Another method is to detect the thickness of playing cards. When the detection element detects that the thickness of playing cards in the card input channel, the conveying channel or the first card output channel is greater than the normal thickness, it can be determined that there are multiple playing cards overlapping. One or more methods can be used in the same card dealing device.

[0091] When it is identified that the playing cards in the conveying channel do not need to be turned over, the card flipping mechanism directly sends out the playing cards; when it is identified that the playing cards in the conveying channel need to be turned over, the card flipping mechanism turns the playing cards over and sends them out. When it is identified that the playing cards need to be withdrawn from the card issuing device, the card issuing motor 4220 drives the first conveying wheel 4203, the second conveying wheel 4205, the card dividing wheel 4202 and the card feeding wheel 4201 to reverse and withdraw the cards. One or more methods can be used in the same card issuing device.

[0092] The present invention identifies the front and back sides of playing cards in a conveying channel and turns over the playing cards in a card turning channel. The two steps do not affect each other, and the cards can be turned over and dealt continuously, which greatly improves the efficiency of turning over and dealing.

[0093] like Fig.13 As shown, in this embodiment, the identification element for identifying the front and back sides of the playing cards is a camera 4238. The camera 4238 and a detection sensor for detecting whether the playing cards are in place are fixed on the conveying bottom wall 4204 or the conveying top wall 4218 of the conveying channel. When the detection sensor detects the playing cards, the camera is started simultaneously or with a delay, so that the camera can just capture the pattern information at the diagonally fixed position of the playing cards in the conveying channel. In this way, the controller can identify the front and back sides of the playing cards based on the pattern information, such as determining it as the front side when it is identified as a character pattern.

[0094] To ensure that the camera can be started in time and capture a panoramic view of the character pattern on the playing card, the following settings are preferred:

[0095] In the first case, the playing card is conveyed forward along the width side in the card-dealing device (i.e., the width of the conveying channel is close to the width of the playing card). In this way, the preferred value range of the width B of the conveying channel is: playing card width + 1mm < B < playing card width + 5mm.

[0096] The value range of the vertical distance M between the center of the camera lens and the left or right side wall of the adjacent conveying channel is: the vertical distance from the character pattern of the playing card to its near-side edge < M < the vertical distance from the character pattern of the playing card to its near-side edge + 5mm.

[0097] The value range of the vertical distance H between the center of the camera lens and the playing card in the conveying channel is: 10mm < H < 15mm.

[0098] Taking a common playing card (Bridge Size, 8.8 cm long and 5.7 cm wide) as an example, 58mm < B < 62mm, 6mm < M < 12mm.

[0099] In the second case, the playing card is conveyed forward along the length side in the card-dealing device (i.e., the width of the conveying channel is close to the length of the playing card). In this way, the preferred value range of the width B of the conveying channel is: playing card length + 1mm < B < playing card length + 5mm.

[0100] The value range of the vertical distance M between the center of the camera lens and the left or right side wall of the adjacent conveying channel is: the vertical distance from the character pattern of the playing card to its near-side edge < M < the vertical distance from the character pattern of the playing card to its near-side edge + 5mm.

[0101] The value range of the vertical distance H between the center of the camera lens and the playing card in the conveying channel is: 10mm < H < 15mm.

[0102] Taking a common playing card (Bridge Size, 8.8 cm long and 5.7 cm wide) as an example, 89mm < B < 93mm, 6mm < M < 12mm.

[0103] In other embodiments, by means of a specific conveying method, speed and direction, the playing cards in the conveying channel can also be made to move closer to and stick to one side, either the left or the right side, of the conveying channel. In this way, the width of the conveying channel will not affect the installation of the camera. It is only necessary to specify that the value range of the vertical distance M between the center of the camera lens and the left or right side wall of the adjacent conveying channel is: the vertical distance from the character pattern of the playing card to its near-side edge < M < the vertical distance from the character pattern of the playing card to its near-side edge + 5 mm. Taking a common playing card (Bridge Size, 8.8 cm long and 5.7 cm wide) as an example, 6 mm < M < 12 mm. The value range of the vertical distance H between the center of the camera lens and the playing card in the conveying channel is: 10 mm < H < 15 mm.

[0104] This can not only avoid unnecessary rubbing and obstruction between the playing cards and the side walls of the conveying channel, but also ensure that when the playing cards are tilted in the conveying channel, the camera can still capture a panoramic view of the character positions on the playing cards.

[0105] In addition, in order to avoid or reduce the influence of uncertain factors such as the forward speed of the playing cards in the conveying channel, it is preferred to arrange the detection sensor for detecting the arrival of the playing cards and the camera 4238 adjacent to each other on the left and right. In this way, after the detection sensor detects the arrival of the playing cards, the camera can be immediately activated to capture a panoramic view of the character positions on the playing cards. In other embodiments, it is also possible to preferably arrange two cameras in the conveying channel. These two cameras are respectively close to the left and right side walls of the conveying channel, and multiple cameras are used for shooting and recognition to improve the accuracy and efficiency of recognizing the front and back sides of the playing cards.

[0106] It should be noted that the width of the above-mentioned conveying channel refers to the effective width within which playing cards can be conveyed in the conveying channel. The left or right side wall of the above-mentioned conveying channel refers to the theoretically left or right side wall of this effective width. In feasible embodiments, the left or right side wall of the conveying channel can be a visible structure formed by a limiting component, a limiting structure, a housing wall surface, etc., or a non-visible structure that actually exists. For example, by controlling the conveying method, speed, direction, etc. of the conveying wheel / roller, the range that the playing cards can reach is restricted to a specific range within the conveying channel, and the left and right boundaries of this specific range are regarded as the left or right side wall of the above-mentioned conveying channel.

[0107] Such as Fig.19As shown, in this embodiment, a first sensor 4235, a second sensor 4236 and a third sensor 4237 are sequentially installed on the conveying top wall 4218 or the conveying bottom wall 4204 of the conveying channel along the advancing direction of the playing cards. The first sensor 4235 and the third sensor 4237 cooperate to detect the length distance covered by the playing cards in the conveying channel at the same time to determine whether there are multiple playing cards overlapping. If the first sensor 4235 and the third sensor 4237 are blocked at the same time (playing cards are detected), it is determined that two partially overlapping playing cards have entered the conveying channel, and the card dealing motor 4220 is reversed to return the playing cards to the card storage box 41 for re-entry and distribution.

[0108] When the playing cards are transported forward along the width edge in the card dealing device (i.e. the width of the transport channel is close to the width of the playing cards), the distance between the first sensor 4235 and the third sensor 4237 is 2mm-3mm larger than the length of the playing cards.

[0109] When the playing cards are transported forward along the length in the card dealing device (i.e. the width of the transport channel is close to the length of the playing cards), the distance between the first sensor 4235 and the third sensor 4237 is 2mm-3mm larger than the width of the playing cards.

[0110] The second sensor 4236 is disposed between the first sensor 4235 and the third sensor 4237. When the second sensor 4236 is blocked (a playing card is detected), the card flipping motor 4230 is activated to flip the card as required. The second sensor 4236 can also cooperate with the first sensor 4235 and the third sensor 4237 to assist in determining whether there are multiple playing cards that partially overlap.

[0111] In this way, after a single playing card is separated by the card separation mechanism, it passes through the first sensor, and the camera takes a photo to identify the front and back sides. When the playing card continues to move forward along the channel to the position of the second sensor, the card flipping mechanism is controlled to turn the playing card according to the identification result. If the first sensor is blocked first and then the third sensor is also blocked at the same time (i.e., the playing card is continuously detected), it means that two playing cards partially overlap and enter the conveying channel. The card dealing motor starts to reverse, and the playing cards entering the card moving channel are returned to the card storage box for single card separation again, thereby ensuring the accuracy of the number of cards dealt.

[0112] The image recognition method is used to identify the front and back of playing cards. Due to the uncertainty of the pattern on the back of the playing cards, it is easy to have the problem of recognition error. Therefore, it is preferred to use a learning mode to identify the front and back of the playing cards. In this way, the playing cards put into the poker machine can be recognized and learned by setting the learning mode to improve the recognition efficiency and accuracy of the playing cards by the poker machine.

[0113] The learning mode can be auto-encoding or convolutional neural network. Neural network does not require a mathematical model. In fact, it is to take a piece of characteristic pattern for comparison. If it matches, it will activate the comparison of other positions or the whole picture. This mode requires a lot of memory and a powerful CPU. Therefore, it is preferred to adopt the learning mode of deep auto-encoding, that is, first formulate a mathematical model (encoder), multi-layer sampling of the input pattern, extract abstract feature information, generate feature code with encoder, and correct the feature code with a certain number of samples.

[0114] In this embodiment, the method of learning patterns to identify the front and back of playing cards is to sample the back patterns or front character patterns of multiple playing cards to generate feature codes, save the feature codes, and then use the feature codes to match the compared patterns to identify the front and back of playing cards.

[0115] A preferred implementation is that the poker machine is provided with a learning mode and a playing mode: in the learning mode, a plurality of playing cards are uniformly placed face down or back down (for example, a new deck of playing cards with the same front and back sides), and the poker machine samples the back patterns or front character patterns of the plurality of playing cards to generate a feature code, and saves the feature code; in the playing mode, the poker machine obtains the back patterns or front character patterns of these playing cards, and uses the feature code to match the compared pattern to identify the front and back of the poker, and controls the card flipping mechanism whether to flip the playing cards based on the identification result.

[0116] like Figures 9 to 12 As shown, the card flipping mechanism includes a first card-discharging pressure wheel 4207, a card flipping wheel 4210, a card flipping pressure wheel 4211 and a second card-discharging pressure wheel 4212. The card flipping wheel 4210 is a driving wheel and is driven to rotate by a card flipping motor 4230 (as shown in FIG.

The card flipping component 4209 for opening or closing the card flipping channel 4224 or the first card output channel 4208 is arranged on the outer side of the card flipping channel 4224 at one end close to the first card output channel 4208. The card pushing component 4216 is arranged on the end of the card flipping channel 4224 away from the first card output channel 4208. The second card output channel 4213 is arranged on the outer side of the card flipping channel 4224 at a position opposite to the card pushing component 4216. The card flipping component 4209 is driven by the card flipping driving mechanism to swing so as to open or close the card flipping channel 4224 or the first card output channel 4208. Fig.11 As shown, when the card flipping component 4209 closes the card flipping channel 4224 or opens the exit of the first card outlet channel 4208, the card input channel 4103, the conveying channel and the first card outlet channel 4208 are connected in sequence, and the playing cards are sent from the first card outlet channel 4208 to the card receiving position of the card receiving seat 2; Fig.12 As shown, when the flop component 4209 opens the flop channel 4224 and closes the exit of the first card-discharging channel 4208, the card-input channel 4103, the conveying channel, the first card-discharging channel 4208, the flop channel 4224 and the second card-discharging channel 4213 are connected in sequence, and the playing cards are blocked by the flop component 4209 after coming out of the first card-discharging channel 4208 and turned to enter the flop channel 4224, and are sent to the end of the flop channel 4224 by the flop wheel 4210 and the flop pressure wheel 4211, and the front end of the playing cards is against the card pushing component 4216, and the playing cards at their rear end return to a straight state after passing through the flop pressure wheel 4211, and under the thrust of the card pushing component 4216, the rear end of the playing cards first enters the second card-discharging channel 4213 and is sent to the card receiving position of the card receiving seat 2 by the flop pressure wheel 4211 and the second card-discharging pressure wheel 4212. In this way, the playing cards passing through the card flipping channel are turned back and forth and flipped 180 degrees to achieve the flipping of the front and back sides of the playing cards.

[0117] It should be noted that, in other embodiments of the present invention, the above-mentioned first card-discharging channel 4208 and the second card-discharging channel 4213 may not be directly connected to the exits of the card receiving position of the card receiving seat 2, that is, one or more channels (or conveying wheels / conveying rollers) for continuing to convey the playing cards may be provided after the first card-discharging channel 4208 and / or the second card-discharging channel 4213 to deliver the playing cards to the card receiving position of the card receiving seat 2.

[0118] Each of the components of the flop wheel 4210, the first card-discharging pressure wheel 4207, the flop wheel 4211 and the second card-discharging pressure wheel 4212 can be a roller part or a plurality of wheel-shaped parts installed on the same shaft. In the present embodiment, the flop wheel 4210, the first card-discharging pressure wheel 4207, the flop wheel 4211 and the second card-discharging pressure wheel 4212 all include a plurality of wheels installed on their respective shafts, and the flop component 4209 also includes a plurality of components installed on the same rotating shaft. The flop component 4209 and the flop wheel 4210 are staggered, so that the structure is simple and the installation and matching are convenient. Rubber rings can be installed on the flop wheel 4210, the first card-discharging pressure wheel 4207, the flop wheel 4211 and / or the second card-discharging pressure wheel 4212 to increase the friction with the playing cards.

[0119] In this embodiment, Figures 11 to 14 As shown, the card flipping channel 4224 includes an inner side wall 4215 of the card flipping channel, and the swing center (card flipping shaft 42091) of the card flipping component 4209 is located in the middle position thereof, so that two swinging ends are formed on both sides of the swing center thereof, and the inner side of the card flipping component 4209 is in an arc shape corresponding to the outer periphery of the card flipping wheel 4210, so that the card flipping component 4209 can not only play a good role in blocking the turning, but also play the role of the outer side wall of the card flipping channel, and there is no need to specially set the outer side wall of the card flipping channel. In other embodiments, such as Fig.24 , Fig.25 , Fig.26 As shown, the swing center (flip axis 42091) of the flip component 4209 is located at one end thereof, and a special outer wall 4239 of the flip channel needs to be provided to ensure smooth passage of playing cards in the flip channel 4224.

[0120] In this embodiment, the card-flipping channel 4224 and the second card-discharging channel 4213 are arranged above the first card-discharging channel 4208 (i.e., the card-flipping wheel 4210, the card-flipping pressure wheel 4211 and the second card-discharging pressure wheel 4212 are located above the first card-discharging pressure wheel 4207). In this way, the height setting of the card-dealing device and even the poker machine is more reasonable, the machine model is thinner and the number of card storage is larger. Of course, if space permits, the card-flipping channel 4224 and the second card-discharging channel 4213 can also be arranged below the first card-discharging channel 4208 (i.e., the card-flipping wheel 4210, the card-flipping pressure wheel 4211 and the second card-discharging pressure wheel 4212 are located below the first card-discharging pressure wheel 4207). Fig.26 shown.

[0121] In order to prevent the playing cards from getting stuck close to the side wall in the flipping channel 4224 and ensure that the playing cards can enter the second card output channel 4213 between the flipping pressure wheel 4211 and the second card output wheel 4212, a transition wheel 4223 is provided on the second card output wheel frame 4214 where the second card output wheel 4212 is installed, close to the flop wheel 4210, to guide the playing cards to between the flopping pressure wheel 4211 and the second card output wheel 4212.

[0122] In order to ensure the conveying pressure and avoid slipping, it is preferred that the first card-discharging pressure wheel 4207 and / or the card-flipping pressure wheel 4211 are given a tendency to press the card-flipping pressure wheel 4210 by respective enabling mechanisms, and it is preferred that the second card-discharging pressure wheel 4212 is given a tendency to press the card-flipping pressure wheel 4211 by enabling mechanisms. These enabling mechanisms can be elastic components such as springs, shrapnel, elastic rings or elastic shafts, or can be elastic enabling mechanisms composed of multiple components. In the present embodiment, the first card-discharging pressure wheel 4207 is rotatably mounted on the first card-discharging pressure wheel frame 4206, the first card-discharging pressure wheel frame 4206 is hinged to the conveying bottom wall 4204 of the conveying channel and a torsion spring is provided on the hinged shaft sleeve to urge the first card-discharging pressure wheel 4207 to press the card-flipping pressure wheel 4210, an elastic rubber ring is installed on the card-flipping pressure wheel 4211 so as to press the card-flipping pressure wheel 4210, and the second card-discharging pressure wheel 4212 is mounted on the second card-discharging pressure wheel frame 4214 through an elastic shaft so as to press the card-flipping pressure wheel 4211. This makes installation easy and the structure simple and reliable.

[0123] The card flipping driving mechanism that drives the card flipping component 4209 to open or close the first card outlet channel 4208 (open the card flipping channel 4224) can be realized by a motor through a reduction mechanism or a transmission mechanism. In this embodiment, Fig.15As shown, the electromagnet 4229 is used for driving, and a crank 4234 is fixed at one end of the flip shaft 42091 of the flip component 4209, and the swing end of the crank 4234 is connected to the movable end of the electromagnet 4229 through the connecting rod 4233, so that when the flip component 4209 needs to move, the electromagnet 4229 pulls the flip component 4209 to swing through the connecting rod 4233 and the crank 4234. Because the flipping action is performed according to the result of the camera identifying the front and back of the playing card, it is selective and intermittent, so the electromagnet structure of this embodiment is more reasonable and the manufacturing cost is low.

[0124] The card pushing component 4216 can be an elastic component such as a spring, a shrapnel, an elastic rubber band, or an elastic energy-enabling mechanism composed of multiple components. In this embodiment, the card pushing component 4216 is a plurality of springs arranged at the end of the channel. This has a simple structure and is easy to install.

[0125] In another alternative embodiment of the card flipping mechanism, the card flipping channel 4224 is directly connected to the card storage box 41, and the second card output channel 4213, the second card output pressure wheel 4212 and the card pushing component 4216 are no longer provided. The flipped playing cards are directly returned to the card storage box for re-dealing. The card-flipping mechanism comprises a first card-discharging pressure wheel, a flop wheel and a flop pressure wheel, the flop wheel is an active wheel and is driven to rotate by a flop motor, the first card-discharging pressure wheel and the flop pressure wheel are both driven wheels, the first card-discharging pressure wheel and the flop pressure wheel are in rolling contact with the flop wheel respectively, a first card-discharging channel is formed between the flop wheel and the first card-discharging pressure wheel, a flop channel is formed between the flop wheel and the flop pressure wheel, the flop wheel is installed on the inner side of the flop channel, the flop channel extends along a partial arc circumference of the flop wheel from a side of the flop wheel close to the first card-discharging channel to the other side of the flop wheel away from the first card-discharging channel, the end of the flop channel is connected to the space in the card storage box, the flop component for opening or closing the flop channel or the first card-discharging channel is arranged on an end of the outside of the flop channel close to the first card-discharging channel, the flop component is driven by the flop driving mechanism to swing to open or close the flop channel or the first card-discharging channel. When the card-flipping component closes the card-flipping passage or opens the first card-discharging passage exit, the card-input passage, the conveying passage and the first card-discharging passage are connected in sequence, and the playing cards are sent from the first card-discharging passage to the card receiving position of the card receiving seat; when the card-flipping component opens the card-flipping passage and closes the first card-discharging passage exit, the card-input passage, the conveying passage, the first card-discharging passage and the card-flipping passage are connected in sequence, and the playing cards are blocked by the card-flipping component after coming out of the first card-discharging passage and turned to enter the card-flipping passage, and are sent to the end of the card-flipping passage by the card-flipping wheel and the card-flipping pressure wheel to enter the card-storing box (a number of conveying wheels and pressure wheels thereof can also be provided between the card-storing box and the card-flipping wheel for conveying playing cards). In this way, the playing cards passing through the card-flipping passage are turned back and forth to realize the flipping of the front and back sides of the playing cards. Other structures are the same as above. This structural scheme can make the depth of the card-storing box shallow and the height of the poker machine low, but the card-dealing efficiency is relatively low and the manufacturing cost is high.

[0126] The poker machine as described above comprises a card receiving seat 2 and a card issuing device, wherein the card issuing device is installed at the center of the card receiving seat 2 and is driven to rotate relative to the card receiving seat 2 by a rotating drive mechanism, and a plurality of card receiving positions are arranged around the card issuing device on the card receiving seat 2. The card issuing device comprises a card storage box 41 and a card issuing device 42, wherein the card storage box 41 and the card issuing device 42 are respectively located on the left and right sides of the card issuing seat 4, and one side of the bottom of the card storage box 41 is connected to a card feeding channel of the card issuing device 42. The card issuing device 42 comprises a card separating mechanism for separating a stack of playing cards arranged in the card storage box into playing cards one by one and sending them to a conveying mechanism, a conveying mechanism for identifying the front and back sides of playing cards and sending the playing cards to a card flipping mechanism, and a card flipping mechanism for flipping the playing cards as needed and sending the playing cards to each card receiving position on the card receiving seat 2.

[0127] The poker card arrangement method of the poker machine as described above comprises the following steps:

[0128] 1) Put the stacked playing cards into a card storage box;

[0129] 2) The card separation mechanism separates the stack of playing cards in the card storage box into individual playing cards and sends them to the conveying mechanism;

[0130] 3) The conveying mechanism identifies the front and back sides of the playing cards and conveys the playing cards to the card flipping mechanism;

[0131] 4) The card flipping mechanism flips the playing cards as needed and sends the playing cards to each receiving position on the card receiving seat.

[0132] Embodiment 2:

[0133] like Fig. 27 , Fig.28 and Fig.29 A poker machine shown includes: a base 1, and a card handling device 6, a card dealer 40 and a card receiving device 20 installed on or inside the base, the card handling device 6 is installed above the card dealer 40, the card dealer includes a card storage box 41 and a card dealing device 42, the outlet of the card handling device 6 is connected to the card storage box 41, and the card receiving device 20 includes a plurality of card receiving positions or card receiving boxes 210 arranged around the card dealer 40, and these card receiving positions or card receiving boxes 210 are driven to rotate relative to the card dealer 40 by a rotating drive mechanism.

[0134] In this embodiment, a central card feeding method is similar to that of a mahjong machine, a panel 3 is provided on the top of the base 1, and the card feeding device includes: a control panel 303 is provided in the center of the panel 3, and the control panel 303 is driven to rise and fall by a central lifting mechanism. When the control panel 303 is raised, a card placement opening for placing playing cards is formed below it, and when the control panel 303 is lowered, the card placement opening is covered, and a card sorting device 6 is installed below the control panel 303.

[0135] The poker machine can be placed on a table as an independent machine for players to use. In this use scenario, multiple openings can be opened on the side wall of the base for players to reach in and take the poker cards, and the corresponding card pushing mechanism can also withdraw the poker cards of each party to multiple card taking positions outside the side wall of the base. Of course, multiple openings can also be opened on the top panel 3 for players to take the poker cards. In more cases, the poker machine is embedded in the central hole of the card table, and only the panel 3 and the control panel 303 are exposed and flush with the table top, so that it will not affect the players' playing of cards, and it is very convenient to manufacture, install and maintain. In this use scenario, a lifting drive mechanism needs to be set on the card receiving device 20 to drive the distributed poker cards of each party to rise to the table top for players to take the poker cards.

[0136] In this embodiment, the base 1 includes a circular bottom plate and a cylindrical side wall, and a power supply and its power switch are installed on the base. A plurality of card loading ports 302 are arranged around the control panel 303 on the panel 3, and a cover plate is installed on the card loading port 302 (when loading cards, the cover plate can be passively lifted up and opened, or can be actively opened by a corresponding driving mechanism), and a card receiving device 20 is arranged below the card loading port 302. It should be noted that the base of the present invention is not limited to a cylindrical shape, and can also be a square column, a polygonal column, a plum blossom column, a frustum, and various other shapes.

[0137] like Fig.32 , Fig.33 and Fig.34As shown, the card sorting device 6 includes a card sorting seat 602, an outer wall 603 of a card sorting channel and a central turntable 606. The card sorting seat 602 is directly or indirectly fixed to the base 1. The central turntable 606 is arranged in the center of the card sorting seat 602. The central turntable 606 is driven to rotate by a turntable motor 609 installed on the card sorting seat 602. The outer wall 603 of the card sorting channel is arranged around the card sorting seat 602. An arcuate card sorting channel for sorting playing cards is formed between the central turntable 606 and the outer wall 603 of the card sorting channel. A plurality of slots for conveying playing cards are arranged at the bottom of the arcuate card sorting channel. A conveying roller 605 for playing cards, a card discharging baffle 607 is arranged at one end of the arc-shaped card discharging channel, a card discharging channel outlet 610 is formed between the card discharging baffle 607 and the bottom of the arc-shaped card discharging channel for feeding the playing cards along its length direction, a card storage box 41 of the card dealer 40 is located below the card discharging channel outlet 610 to receive the fed playing cards, wherein the width of the arc-shaped card discharging channel is smaller than the length of the playing cards and larger than the width of the playing cards, the distance between two adjacent conveying rollers 605 is smaller than the length of the playing cards, and the width of the card discharging channel outlet 610 is close to the width of the playing cards. In this way, the chaotic playing cards put in from the card placement port are rotated and moved into the arc-shaped card sorting channel via the central turntable 606. The playing cards whose length direction is basically consistent with the conveying direction of the conveying roller 605 in the arc-shaped card sorting channel are sent out from the card sorting channel outlet 610 by the conveying roller 605. The playing cards whose length direction is inconsistent with the conveying direction of the conveying roller 605 in the arc-shaped card sorting channel are respectively rotated by the central turntable 606 and the conveying roller 605 on the inner and outer sides until the length direction is basically consistent with the conveying direction of the conveying roller 605 in the arc-shaped card sorting channel and sent out, thereby arranging the chaotic and disordered playing cards into width direction and sending them out to achieve card sorting. The preferred mode is that the rotation direction of the central turntable 606 is opposite to the direction in which the conveying roller 605 conveys the playing cards to promote the rotation of playing cards with inconsistent directions, thereby arranging the playing cards into a certain direction and improving the efficiency of card sorting.

[0138] like Fig.35 As shown, the top of the center turntable 606 is a turntable upper conical surface 6061, and the lower edge of the turntable upper conical surface 6061 is formed with a plurality of turntable card dialing inclined surfaces 6062 arranged along the circumference of the center turntable 606 and protruding upward, and the lower part of the center turntable 606 is formed with a turntable side wall 6063 near the bottom of the card sorting channel. In this way, the turntable upper conical surface 6061 helps the playing cards to move to the edges of the center turntable 606 so as to fall into the card sorting channel, the turntable card dialing inclined surface 6062 can prevent the playing cards from getting stuck or floating while turning the playing cards, and the turntable side wall 6063 is vertically arranged to limit and guide the playing cards at the bottom of the card sorting channel to ensure the conveying direction.

[0139] In order to further improve the efficiency of card sorting and card feeding in the card sorting channel, it is preferred that the plurality of conveying rollers 605 are distributed along the radial direction of the circular center turntable 606, and the conveying rollers 605 are tapered rollers with a small inner end radius and a large outer end radius. In this way, different conveying areas and conveying speeds are formed on the inner and outer sides of the card sorting channel, so that the playing cards can be quickly conveyed in the arc-shaped card sorting channel, and the playing cards can be prevented from getting stuck or floating.

[0140] In order to further improve the efficiency of card sorting, preferably, the outer wall 603 of the card sorting channel is supported by a plurality of outer supporting rollers 608 and mounted on the card sorting seat 602 and driven to rotate by the outer motor 604. In this way, the outer wall 603 of the card sorting channel can also rotate actively, and the efficiency of card sorting can be improved by reasonably controlling the rotation direction and / or rotation speed of the central turntable 606 and the outer wall 603 of the card sorting channel, thereby preventing the playing cards from getting stuck and floating.

[0141] In a preferred embodiment, an outer gear and a bottom gear are integrally formed or fixed on the outer side wall 603 of the card sorting channel, and an outer motor 604 fixed on the card sorting seat 602 or the base 1 drives the outer side wall 603 of the card sorting channel to rotate through the output gear meshing with the outer gear, and the bottom gear meshes with the outer end gear of the conveying roller 605 to drive the conveying roller 605 to rotate. This has a simple and reasonable structure, is easy to manufacture and assemble, and has low cost.

[0142] In order to further improve the card-discharging efficiency and stability, a card-discharging mechanism is installed at the card-discharging channel outlet 610. The specific structure of the card-discharging mechanism can refer to patent documents such as WO2018196759A1 and CN105854275, which generally includes a card-discharging active roller wheel and a pressure roller driven by a card-discharging motor.

[0143] In this embodiment, an upper shell 601 for covering the center turntable 606 and the upper part of the card handling channel is fixed above the card handling seat 602, so that the card handling channel forms a relatively closed space, which prevents the inserted playing cards from entering other mechanisms of the movement and causing confusion, and at the same time can improve the efficiency of card handling. Of course, in other embodiments, a shell for covering the card handling seat 602 and the transmission components thereon can also be set on the side or bottom of the card handling seat 602. Accordingly, the above-mentioned card discharging mechanism can be installed on the card discharging baffle 607, or on the card handling seat 502 or the upper shell 601.

[0144] In this embodiment, the other end of the arc-shaped card handling channel is closed, and the card storage box is located between the closed end and the exit end of the arc-shaped card handling channel. In other embodiments, in order to further improve the card handling efficiency of the card handling device, a card handling channel exit is provided at each end of the arc-shaped card handling channel, and the card storage box is located between the two exits, and the playing cards coming out of the two exits directly enter the card storage box. Generally speaking, the two exits can be staggered to output cards by controlling the rotation speed and rotation direction of the central turntable, the conveying roller and / or the outer wall of the card handling channel. This can avoid the problems of too long transportation distance for some playing cards at one exit, dead corner card jams, etc., so as to achieve fast card output and improve card handling efficiency.

[0145] In this embodiment, the control panel 303 is provided with buttons for controlling the actions of starting, shuffling and loading cards. When playing cards, the player can set the playing rules on the control panel. The poker machine deals cards to each player according to the set playing rules. When dealing cards, the playing cards of each player are randomly dealt by the card dealer and are intermittently dealt to the receiving position or receiving box of each party according to the number of cards set by the player. The control panel 303 and its central lifting mechanism can refer to the central lifting mechanism of the mahjong machine, such as the central lifting mechanism disclosed in patent documents such as publication numbers CN206881093, CN206881095, and CN205235367.

[0146] In this embodiment, Fig.34 As shown, the control panel 303 includes a control panel panel 3031 , a control panel circuit board 3032 and a control panel base 3033 . The control panel circuit board 3032 is fixed in the control panel base 3033 , and the control panel panel 3031 covers the control panel circuit board 3032 . The central lifting mechanism includes a lifting guide rod 304, a lifting seat 305, a central lifting cam 307 and a central lifting motor 308. The control panel base 3033 is fixed to the upper end of the lifting guide rod 304. The lifting seat 305 is sleeved on the outside of the lifting guide rod 304. The lifting seat 305 is fixed on the card sorting seat 602. The lower part of the lifting seat 305 is sleeved with a central lifting cam 307. Through grooves are provided on both sides of the lifting seat 305. A support rod is fixed to the lower end of the lifting guide rod 304. Both ends of the support rod extend out of the through groove on the lifting seat 305 and can move up and down along the through groove. The two protruding ends of the support rod are against the cam curve surface on the central lifting cam 307. The central lifting cam 307 is driven to rotate by the central lifting motor 308, thereby driving the support rod and its lifting guide rod 304 to move up and down, and then driving the control panel at the top of the lifting guide rod 304 to rise and fall.

[0147] In this embodiment, the outer side of the central lifting cam 307 is integrally formed or fixed with an external gear, and is connected to the central lifting motor 308 fixed on the card sorting seat 602 through the lifting intermediate gear 306 and / or the transmission belt. In other embodiments, the central lifting cam 307 and the central lifting motor 308 can also be connected through other transmission methods, such as a speed reduction mechanism or a chain transmission. In other embodiments, rollers or bearings can also be installed on the two protruding ends of the support rod to abut against the cam curve surface on the central lifting cam 307.

[0148] In this embodiment, the central turntable 606 is sleeved outside the lifting seat 305, and the upper end of the lifting seat 305 extends out of the top of the central turntable 606. The two are connected by a bearing and can rotate relatively. The turntable motor 609 is installed on the card sorting seat 602 and is connected to the central turntable 606 through a transmission belt and / or an intermediate gear 6091. The inner side wall of the bottom of the central turntable 606 is integrally formed or fixed with an internal gear ring, which is meshed with the intermediate gear 6091. In other embodiments, the central turntable 606 and the turntable motor 609 can also be connected by other transmission methods, such as a speed reduction mechanism or chain transmission.

[0149] In this embodiment, the internal structure of the card distributor 40 is basically the same as that of the embodiment 1, and the main difference is that in this embodiment, the conveying channel is extended to adapt to the setting of the card handling device 6, and the card distributor 40 is fixed and does not rotate, and the card receiving position or the card receiving box in the card receiving device rotates to achieve random card receiving. The specific description is as follows:

[0150] like Fig.28 , Fig.36 , Fig.37 , Fig.38 As shown, the card dealer 40 is fixed on the base 1 and is located below the card handling seat 602. The card dealer includes a card storage box 41 and a card dealing device 42. The upper opening of the card storage box 41 is located below the card handling passage outlet 610. The bottom side of the card storage box 41 is connected to the card feeding passage of the card dealing device 42. The card dealing device 42 includes a card separation mechanism, a conveying mechanism and a card flipping mechanism. The card flipping mechanism is located below the outer side of the central turntable 606. In this embodiment, the card storage box 41, the card separation mechanism, the conveying mechanism and the card flipping mechanism convey the playing cards along the width direction of the playing cards. Their structures, principles, action processes and methods can all adopt the structures, principles, action processes and methods in Example 1 and various alternative structures, principles, action processes and methods in Example 1, and the same contents will not be repeated.

[0151] On the basis of Example 1, in this embodiment, the conveying channel of the conveying mechanism is extended. Therefore, it is preferred to set two identification elements (cameras 4238) for identifying the front and back of playing cards on the conveying bottom wall 4204 or the conveying top wall 4218 of the conveying channel. Preferably, the two identification elements are arranged diagonally opposite to the playing cards to detect the two patterns on the diagonal opposite sides of the front of the playing cards respectively, so as to improve the recognition accuracy and efficiency of the front and back of the playing cards. The two identification elements can be triggered by the same detection sensor for detecting the position of the playing cards, or they can be triggered by two detection sensors for detecting the position of the playing cards respectively.

When the playing cards pass between the thickness measuring wheel 4241 and the thickness measuring conveying wheel 4243, the thickness measuring wheel 4241 and the rotating member 4240 are lifted up, and the thickness measuring sensor 4242 can determine the thickness of the playing cards passing by according to the up and down change distance of the movable end of the rotating member 4240. When the measured thickness is close to or even exceeds the thickness of two playing cards, the controller determines that there are two or more playing cards overlapping, and the conveying mechanism returns the playing cards to the card storage box 41 for re-entry and separation. This can further reduce the occurrence of separation errors and malfunctions. The thickness measuring assembly can be used in conjunction with the thickness measuring structure or method in Example 1, or it can be used alone. Of course, in this embodiment, only the thickness measuring structure or method in Example 1 and its various alternative structures, principles, action processes, and methods can be used.
