Description

Technical Field

[0001] The utility model relates to the field of card dealing machines, in particular to a card distributing system. Background Art

[0002] Card games are not only a popular form of entertainment, but also include throwing eggs, fighting landlords, etc. These card games are also intellectual sports. According to different game rules, one or more decks of cards are usually used to play the game. Each deck of cards includes four types: spades, hearts, clubs and diamonds. Each suit includes thirteen cards of different points, including 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, J, Q, and K. Under different game rules, each card is sorted according to its suit and point value.

[0003] In the process of playing card games, the cards need to be reshuffled and redistributed after one round is finished before continuing to the next round. Currently, the actions of shuffling and distributing are mainly performed manually. Of course, they can also be replaced by mechanical devices, such as automatic card dealing machines on the market. However, whether it is manual or automatic shuffling and distribution, in general card games, players need to sort the chaotic cards themselves after getting the cards.

[0004] Although automatic card dealing machines have improved the game speed and achieved a more thorough and random shuffling compared to manual dealing, in order to further improve the game speed and the player's gaming experience, the utility model proposes a card distribution system that can sort the shuffled cards according to the rules, so that the player does not need to sort the cards when he gets them. Utility Model Content

[0005] In order to further improve the game speed and the game experience of the players, the utility model provides a card system, which can directly send the components of the cards corresponding to each player to the player after sorting them.

[0006] According to the first aspect of the present invention, a playing card distribution system is provided, comprising:

[0007] A card collection mechanism, comprising a card collection bin and a moving device, wherein the card collection bin is used to collect a preset number of cards that are randomly arranged, and the moving device is used to move the cards to be issued from the card collection bin one by one;

[0008] A playing card recognition device, used for recognizing the suit and points of the playing cards to be issued from the playing card collection bin;

[0009] A card buffer mechanism, comprising at least M card units distributed along the same straight line, each card unit comprising N card slots distributed along the same straight line, the card slots being used to sequentially match and receive cards to be issued from the card collection bin moved by the moving device, wherein the cards in all the card slots under each of the card units are arranged according to a preset rule;

[0010] As a preferred embodiment, the moving device is located below the card collection bin, the cards to be issued from the card collection bin are the cards at the bottom of the card collection bin, the moving device is used to move the cards at the bottom of the card collection bin one by one, and the card recognition device recognizes the suit and points of the cards at the bottom of the card collection bin.

[0011] It should be noted that the number of card units M and the number of card slots N can be determined according to the number of players and the rules of the game. For example, in the Pai Egg card game, M can be set to 4, that is, there are 4 card units, and N can be set to 27, that is, there are 27 slots under each card unit, wherein the cards in all the card slots under each of the card units are all the cards that are ultimately sent to the player. These numbers determined according to actual conditions are not elaborated here. It is understandable that those skilled in the art can define the cards that need to be received by each card slot through a computer, that is, the first card slot under the first card unit receives a card with a suit of diamonds and a point value of 1, the second card slot under the first card unit receives a card with a suit of clubs and a point value of 5, and so on; and when defining each card slot, the card slots under each card unit are sorted according to the rules, that is, the card slots under each card unit are arranged from top to bottom or from bottom to top according to suit and / or point value, then, when all the card slots under the card unit have received the corresponding cards, the card unit can output a deck of cards that have been sorted and can be delivered to the player in the order of the rules.

[0012] In some embodiments, the card recognition device includes a camera module, a hollow area is provided at the bottom of the card collection bin, and the camera module is arranged below the hollow area. The camera module collects the suit and point information of the cards to be issued from the card collection bin through the hollow area, and sends the suit and point information of the cards to be issued from the card collection bin to the controller.

[0013] It should be noted that each card has a mark that can identify the suit and number of points. The hollow area only needs to be designed to allow the identification mark of the cards to be issued from the card collection bin to leak out, so that the camera module can capture the mark image. Its shape and specific position are not limited here. The camera module identifies the number of points and suit of the cards through the collected identification mark image. The image recognition technology used by the camera module is a relatively commonly used technology in the field of image recognition, which will not be elaborated here.

[0014] In some embodiments, the card distribution system also includes a controller for determining the card unit corresponding to the cards to be issued from the card collection bin and the card slot under the card unit based on the suit and points of the cards to be issued from the card collection bin identified by the card recognition device, and controlling the card cache mechanism to move the card slot under the card unit to the exit of the mobile device in the card collection mechanism.

[0015] It should be noted that the controller may include one or more independent circuit units and their programs or circuit sub-units or their programs integrated in various mechanisms.

[0016] In some embodiments, the card recognition device sets a predetermined time interval and takes pictures and collects identification images in a time sequence. It can be understood that the time interval is determined according to the transmission speed of the cards to be issued from the card collection bin. It only needs to set the time interval to satisfy the requirement of taking pictures before each card is transmitted.

[0017] In some embodiments, the card recognition device also includes a shooting sensor, which is arranged on the moving path of the cards to be issued from the card collection bin in the card collection mechanism. When the cards to be issued from the card collection bin move along the card moving path to the detection area detected by the shooting sensor, the camera module is triggered to shoot. Specifically, the shooting sensor can be one of the sensors that can detect cards, such as an infrared sensor, a photoelectric sensor, etc.

[0018] It should be noted that when the cards to be issued from the card collection bin move to the position where the identification mark just leaks out and the camera area of ​​the camera module is aligned with the mark, the position is the installation position of the shooting sensor. The specific shooting sensor position setting is related to the hollow area and the position of the camera module. It can be understood that as long as it can be ensured that the identification mark can be photographed through the hollow area when the cards pass through the detection area of ​​the shooting sensor to trigger the camera module to shoot, technical personnel in this field can correct the position through continuous experiments, and will not elaborate on it here.

[0019] In some embodiments, the moving device includes a first motor and a first synchronous belt driven by the first motor, and the first synchronous belt is arranged below the card collection bin. The cards to be issued from the card collection bin are in contact with the first synchronous belt. When the first motor drives the first synchronous belt to move, the first synchronous belt relies on friction to move the cards to be issued from the card collection bin out of the card collection bin one by one in a straight line.

[0020] In some implementations, the width of the first timing belt is smaller than the width of a playing card.

[0021] It should be noted that because the cards to be issued from the card collection bin not only need to be transmitted, but also need to leave marks to allow the card recognition device to collect images, the width of the first synchronous belt must not be greater than the width of the cards to prevent the first synchronous belt from completely covering the identification marks of the cards.

[0022] In some embodiments, the mobile device includes a second motor, a second synchronous belt driven by the second motor, and a first roller and a second roller driven by the second synchronous belt. The cards to be issued from the card collection bin are sequentially transmitted to the exit of the mobile device through the first roller and the second roller.

[0023] In some embodiments, the mobile device includes a second motor, a second synchronous belt, a first roller, a reduction synchronous belt and a second roller. The second motor drives the second roller to rotate via the second synchronous belt, and the second roller drives the first roller to rotate via the reduction synchronous belt. The cards to be issued from the card collection bin are transmitted to the outlet of the mobile device via the first roller and the second roller in sequence, and the ratio of the linear velocity of the first roller to the linear velocity of the second roller is 1:2.

[0024] Furthermore, the second motor includes a driving axle, the first roller includes a driven axle, the second roller includes a driven axle and a driving axle, the driving axle of the second motor is drivingly connected to the driven axle of the second roller via the second synchronous belt, the driving axle of the second roller is drivingly connected to the driven axle of the first roller via the reduction synchronous belt, the wheel radii of the driving axle of the second motor, the driven axle of the first roller and the driven axle of the second roller are all equal, and the ratio of the wheel radius of the driving axle of the second roller to the wheel radius of the driven axle of the first roller is 1:2.

[0025] It should be noted that the two rollers are designed with a speed difference, which accelerates the cards out of the exit and increases the distance between the cards and the next card, thereby further preventing the phenomenon of two playing cards being delivered to the exit at the same time.

[0026] In some embodiments, the exit of the mobile device is a limited exit, and the height of the limited exit only allows one card to pass through.

[0027] In some embodiments, the card collection mechanism further includes a card pressing plate, which is used to press the cards in the card collection bin so that the cards to be sent out in the card collection bin are kept in close contact with the mobile device. The pressing force of the card pressing plate can ensure that all the cards in the card collection bin are pressed smoothly so that the cards to be sent out in the card collection bin are kept in close contact with the mobile device, so that the mobile device can send out the cards one by one through friction.

[0028] In some embodiments, the card pressing plate is rotatably disposed along a rotating axis on one side of the top of the card collection bin. When it is necessary to collect cards, the card pressing plate is rotated to open the card inlet of the card collection bin. After the collection is completed, the card pressing plate is rotated so that the card pressing plate applies a downward pressure due to gravity from the top of the collection bin to compact the cards in the card collection bin.

[0029] In some embodiments, the card collection mechanism also includes a card position sensor, which is arranged on the card output path of the mobile device, and is used to detect the push-out position of the cards to be issued from the card collection bin, and send the information of the push-out position of the cards to be issued from the card collection bin to the controller; in actual use, the card position sensor is used to detect failures in the process of inserting cards from the card collection bin into the card cache mechanism (failure forms include cards not being issued in place and not being issued, and causes of failures include card deformation or missing corners). When a card insertion failure occurs, the first motor drives the mobile device to withdraw the card and then reinsert it. Multiple failures will report a fault, which can be solved by manual card replacement.

[0030] In some embodiments, a predetermined interval is provided between each of the card units of the card buffer mechanism, and the interval is set to facilitate distinguishing the card units when taking cards later.

[0031] In some embodiments, each of the card units in the card buffer mechanism and the card slots under the card units can reciprocate vertically relative to the exit of the moving device.

[0032] It should be noted that the card collection mechanism is relatively static. In order to accommodate different cards entering different card slots, each of the card units can move vertically relative to the transmission outlet. When the card recognition device recognizes the suit and point information of the cards to be sent out from the card collection bin, the controller will quickly move the card slot corresponding to the suit and point information to the outlet to receive the cards. The vertical movement method is more accurate, faster and easier to implement than other movement methods.

[0033] In some embodiments, the card cache mechanism further includes a third motor, the card unit includes a cache rack consisting of a top plate and two side plates fixedly connected to the top plate and arranged opposite to each other, the third motor drives the cache rack to move in a straight line, and M card units are vertically distributed on the opposite inner sides of the two side plates in the cache rack, and each of the card units includes N vertically distributed card slots. According to the movement mode of each of the card units in the above-mentioned card cache mechanism, the arrangement mode of each of the card units in the card cache mechanism is matched.

[0034] In some embodiments, a first drive block is fixedly provided on the outer side of one of the two side panels, and the first drive block is detachably mounted on a straight section of a third synchronous belt. The third motor drives the third synchronous belt to reciprocate, thereby driving the card unit to reciprocate vertically along a straight line.

[0035] In some embodiments, a first drive block is fixedly provided on the outer side of one of the two side panels, and the first drive block is detachably mounted on a straight section of a third synchronous belt. The third motor drives the third synchronous belt to reciprocate, thereby driving the card unit to reciprocate vertically along a straight line.

[0036] In some embodiments, a guide rail is arranged parallel to one side of the straight section of the third synchronous belt, the first drive block is slidably connected to the guide rail, and each of the card units performs vertical reciprocating motion along the guide rail. The setting of the guide rail can calibrate the moving path of the cache rack, so that the movement of the cache rack under the control of the third motor is more precise.

[0037] In some embodiments, the card cache mechanism also includes a positioning sensor, which is used to detect the position of a predetermined card unit and send the position information of the predetermined card unit to the controller. The positioning sensor can also allow the card cache mechanism to perform self-check and reset before inserting cards, further improving the accuracy of the cache rack movement under the control of the third motor.

[0038] In some embodiments, each of the card units in the card cache mechanism can reciprocate horizontally relative to the exit of the mobile device, and the card slot under each of the card units can reciprocate vertically relative to the exit of the mobile device.

[0039] In some embodiments, the playing card cache mechanism includes M playing card units distributed horizontally, and each of the playing card units includes N playing card slots distributed vertically.

[0040] In some embodiments, the card buffer mechanism further includes a card blocker for limiting the position of the cards entering the card unit to prevent the risk of subsequent bending of the cards due to the cards protruding relative to the card slot after insertion.

[0041] In some embodiments, the card blocker may be a baffle fixedly disposed on the other side of the cache rack opposite to the card entry side, and is used to limit the playing cards entering the card positions.

[0042] In some embodiments, the card buffer mechanism further includes a rebound limiter for limiting the position of the cards entering the card unit to prevent the risk of the cards being bent due to the cards rebounding after insertion and protruding relative to the card slot.

[0043] In some embodiments, the rebound limiter can be an elastic member disposed on one of the two side panels, used to apply lateral force to clamp the playing cards entering the cache rack.

[0044] In some embodiments, the rebound limiter can be a barb member provided on the card entry side of the card rack, for limiting the position of the playing cards after entering the card rack.

[0045] In some embodiments, the playing card distribution system further comprises:

[0046] The card output mechanism is used to sequentially receive the cards in all N card slots in any one of the card units, and transfer the received multiple cards to a designated position on the card table.

[0047] In some embodiments, the card output mechanism includes:

[0048] A card box, each card box is used to accommodate the cards in all N card slots under each of the card units.

[0049] A card taking device, used for taking out cards from all N card slots in each of the card units one by one in order;

[0050] The turntable device is used to carry the card shoe and move the card shoe to a designated position on the card table.

[0051] In some embodiments, the card retrieval device includes a card picker and a power assembly that drives the card picker, the power assembly drives the card picker to move back and forth in a straight line, the moving path of the card picker is perpendicular to the moving path of the card unit and the card slot under the card unit, the card unit and the card slot under the card unit are arranged above the moving path of the card picker, when the card picker moves along the moving path to the card unit and the bottom of the card unit, an upper folding part of the card picker moves the card unit and all the cards under the card unit to remove the card unit and send it to the card box.

[0052] It should be noted that the card puller takes the cards from all the card slots under each card unit from bottom to top in sequence, with the card unit as a portion. In actual use, after each of the card units has received the designated cards, it moves to the top, and the card puller moves toward the card unit to the top so that the card puller is directly below the card unit. The card unit is then moved downward by a predetermined distance so that the upper folding portion of the card puller is aligned with all the card slots under the lowest card unit. The card puller is then driven to move toward the card box to take out the card unit and all the cards under the card unit and send them to the card box, and so on, until all the cards in N card units are taken out and sent to the card box.

[0053] In some embodiments, when the card picker takes cards, the card unit and the lowest card under the card unit are completely in contact with the bearing surface of the card picker.

[0054] In some embodiments, the card box is arranged at the other end of the card picker's moving path relative to one end of the card unit, and the card box is offset from the card picker. When the card picker takes a card from the card unit, it is transferred to the card box for offset separation so that the card falls into the card box.

[0055] In some embodiments, an oblique guide foot extends from one end of the card box close to the card pusher toward the bearing surface of the card pusher, and the extended end of the oblique guide foot is located below the bearing surface of the card pusher and forms an angle with the bearing surface of the card pusher. When the card pusher carries a card close to the card box, the bottom surface of the card contacts the oblique guide foot, and the card is separated from the bearing surface of the card pusher along the guidance of the oblique guide foot and is continuously pushed into the card box by the upper folding portion.

[0056] In some embodiments, the power assembly includes a fourth synchronous belt, a fourth motor that drives the fourth synchronous belt to move, and a guide rail parallel to the moving path of the card pusher. The card pusher is slidably mounted on the guide rail via a driving block. The card pusher is also detachably mounted on the fourth synchronous belt via the driving block. When the fourth motor drives the fourth synchronous belt to move, it further drives the card pusher to reciprocate along the guide rail. The setting of the guide rail can calibrate the moving path of the card pusher, so that the movement of the card pusher under the control of the fourth motor is more precise.

[0057] In some embodiments, a photoelectric sensor is provided on the moving path of the card pusher for self-checking and resetting the card pusher.

[0058] In some embodiments, the turntable device includes a turntable and a fifth motor driving the turntable to rotate, and the plurality of card boxes are fixedly mounted on the turntable at predetermined intervals. The fifth motor drives the turntable to rotate and moves the card boxes one by one to the card retrieval position for retrieval.

[0059] In some embodiments, the turntable device further includes a locator for locating the position of the turntable or the card shoe.

[0060] In some embodiments, the card buffer mechanism further includes an arched card protector, which is fixedly disposed on the card moving path between the card buffer mechanism and the card output mechanism to prevent the cards from shaking left and right when the card output mechanism is taking the cards out of the card buffer mechanism.

[0061] Compared with the prior art, the utility model has the following beneficial effects:

[0062] The utility model collects disorderly arranged cards based on the card collection bin of the card collection mechanism, and then outputs the cards in the card collection bin one by one through the moving device of the card collection mechanism. At the same time of output, the card recognition device is combined to identify the suit and point information of the cards to be issued from the card collection bin to be output, and then the controller controls the pre-set card buffer mechanism to move to correspondingly receive the cards to be issued from the card collection bin. The pre-set card buffer mechanism corresponds to the cards that each card slot under each card unit should receive, and What is different from the prior art is that each card slot under each card unit is sorted based on rules, that is, after all the card slots under all the card units have received all the cards, all the cards in each card unit have been sorted from top to bottom or from bottom to top based on suit and / or points, and can be sent directly to the player, thereby speeding up the game efficiency and improving the player experience. In addition, the card recognition device and the card cache mechanism can be combined to check the integrity of the points, suit and number of cards to prevent missing cards or duplicate cards in the game.

[0086] Unless otherwise specified, the systems and methods used in the present invention are conventional systems and methods in the technical field.

[0087] A playing card distribution system provided by the utility model is first described in detail below in conjunction with the accompanying drawings.

[0088] First, see Figure 1 , Figure 2 , Fig. 9 , Fig.14 and Fig.15 The first embodiment of the present utility model provides a card distribution system, which includes:

[0089] A playing card collection mechanism 1, comprising a playing card collection bin 10 and a moving device located below the playing card collection bin 10, wherein the playing card collection bin 10 is used to collect a preset number of playing cards 0 arranged in disorder, and the moving device is used to move the playing cards at the bottom of the playing card collection bin 10 one by one;

[0090] A playing card recognition device 2, used to recognize the suit and point information of the playing card at the bottom of the playing card collection bin 10;

[0091] The card buffer mechanism 3 comprises at least M card units distributed along the same straight line, each card unit comprises N card slots distributed along the same straight line, the card slots are used to sequentially match and receive the cards at the bottom of the card collection bin 10 moved by the moving device, wherein all the card slots under each of the card units are arranged in order according to a preset rule, wherein the preset rule may be:

[0092] 1. Arrange in order according to the points and / or suits of the cards, and the arrangement in order includes the following situations: 1. Arrange from bottom to top according to the points from small to large; 2. Arrange from top to bottom according to the points from small to large; 3. Arrange from bottom to top according to the suit from small to large (the size of the suit can be set by a technician in this field according to different game rules, such as from large to small for black, red, and plum); 4. Arrange from top to bottom according to the suit from small to large (the size of the suit can be set by a technician in this field according to different game rules, such as from large to small for black, red, and plum); 5. Arrange from bottom to top according to the points and suit from small to large, among which the points are given priority; 6. Arrange from top to bottom according to the points and suit from small to large, among which the points are given priority; 7. Arrange from bottom to top according to the suit and points from small to large, among which the suit is given priority; 8. Arrange from top to bottom according to the suit and points from small to large.

[0093] 2. Arrange in order according to the strength of the cards. For example, in the rules of throwing eggs, combined with Table 1, arrange from bottom to top according to the strength of the cards from small to large, or arrange from top to bottom according to the strength of the cards from small to large.

[0094] Card Type Card Strength Four Kings 14 Eight-headed bomb 13 Seven-headed bomb 12 Six-headed bomb 11 Flush 10 Five-headed bomb 9 Four bombs 8 Two Kings 7 Samsoon 6 Triple Pair 5 Three with two 4 Variegated Straight 3 Three without 2 Pair 1 Single Card 0

[0095] Table 1

[0096] It can be understood that different card types in Table 1 correspond to different card strengths, and the definition of card strength can be modified according to different game rules (such as the card strength of three with two is 6, the card strength of a motley straight is 5, the card strength of three straights is 4, the card strength of three consecutive pairs is 3, and so on). The definition of card strength is only used to help determine the priority when sorting the cards. Therefore, in specific applications, the arrangement of cards according to card strength is not limited to the card strength defined in Table 1.

[0097] As an example, in a preferred embodiment of the present invention, the card strength can be set so that the card type with high card strength can suppress the card type with low card strength in the corresponding game; for example, in the game of throwing eggs, a straight flush can suppress a five-head bomb, that is, the card strength of a straight flush is greater than the card strength of a five-head bomb;

[0098] In other preferred implementations, the card strength can also be set so that the number of cards corresponding to the card type with high card strength is greater than the number of cards corresponding to the card type with low card strength, such as the number of cards for the three straight card type is 6, and the number of cards for the three with two card type is 5.

[0099] Of course, according to different playing card rules, different card types can match different card strengths. The card types and card strength matching under other rules will not be elaborated here.

[0100] A card output mechanism 4 is used to sequentially receive the cards in all N card slots in any one of the card units, and transfer the received cards to a designated position on the card table;

[0101] The controller is used to determine the card unit corresponding to the bottom card of the card collection bin 10 and the card slot under the card unit according to the suit and point information of the card at the bottom of the card collection bin 10 identified by the card recognition device 2, and control the card cache mechanism 3 to move the card slot under the card unit to the exit of the moving device in the card collection mechanism. It should be noted that the controller stores the serial number and corresponding position of each card unit and the card slot under the card unit.

[0102] It should be noted that the number of card units M and the number of card slots N can be determined according to the number of players and the rules of the game. For example, in the game of throwing eggs, two decks of cards totaling 108 cards are needed, then M can be set to 4, that is, 4 card units are provided, and N is 27, that is, each card unit has 27 card slots for storing cards; for another example, in the game of Landlord, a deck of cards totaling 54 cards is needed, and M can be set to 4, that is, 4 card units, and N is 17, then the 17 card slots under 3 card units all store 17 cards, and the 17 card slots under 1 card unit store 3 cards, wherein the cards in all the card slots under each of the said card units are all the cards finally sent to the player, and these numbers determined according to the actual situation will not be elaborated here. It is understandable that those skilled in the art can define the cards that need to be received by each card slot through a computer, that is, the first card slot under the first card unit receives a card with a suit of diamonds and a point value of 1, the second card slot under the first card unit receives a card with a suit of clubs and a point value of 5, and so on; and when defining each card slot, the cards received by the card slot under each card unit are sorted according to the rules, that is, the card slots under each card unit are arranged from top to bottom or from bottom to top according to suit and / or points, then, when all the card slots under the card unit have received the corresponding cards, the card unit can output a hand of cards that are sorted according to the rules and can be delivered to the player.

[0103] It should also be noted that the controller may include one or more independent circuit units and their programs or circuit sub-units or their programs integrated in various mechanisms.

[0104] The operation process of the card distribution system is specifically as follows: based on the card collection bin 10 of the card collection mechanism 1, the disorderly arranged cards are recovered, and then the moving device of the card collection mechanism 1 is used to output the cards in the card collection bin 10 one by one. While outputting, the card recognition device 2 is combined to identify the suit and point information of the card at the bottom of the card collection bin 10 to be output, and then the controller controls the pre-defined card buffer mechanism 3 to move to receive the card at the bottom of the card collection bin 10. The pre-set card buffer mechanism 3 corresponds to the cards that each card slot under each card unit should receive, and each card slot under each card unit is sorted based on rules, that is, when all the slots under all the card units have received all the cards, all the cards in each card unit are sorted from top to bottom or from bottom to top based on suit and / or point, and finally the sorted cards are directly transferred to the player through the card output mechanism 4.

[0105] Next, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 , specifically introduce the playing card collection mechanism 1 and the playing card identification device 2:

[0106] Among them, combined Figure 2 and Figure 4 The card recognition device 2 is a camera module. A hollow area 11 is provided at the bottom of the card collection bin 10. The camera module is arranged below the hollow area 11. The camera module collects the suit and point information of the bottom card in the card collection bin 10 through the hollow area 11, and sends the suit and point information of the bottom card in the card collection bin 10 to the controller. It should be noted that each card has an identification mark that can identify the suit and point. The hollow area 11 only needs to be designed to allow the identification mark of the bottom card in the card collection bin 10 to leak out, so that the camera module can capture the identification mark image. Its shape and specific position are not limited here. The camera module identifies the points and suit of the card through the collected identification mark image. The image recognition technology used by the camera module is a relatively commonly used technology in the field of image recognition, which will not be elaborated here.

[0107] In some embodiments, the card recognition device 2 sets a predetermined time interval and takes pictures and collects identification images in a time sequence. It can be understood that the time interval is determined according to the transmission speed of the bottom card in the card collection bin 10. It only needs to set the time interval to meet the requirement of taking pictures before each card is transmitted.

[0108] Combination Figure 2 and Figure 4In some embodiments, the card recognition device 2 further includes a shooting sensor 21, which is arranged on the moving path of the card at the bottom of the card collection bin 10 in the card collection mechanism 1. When the card at the bottom of the card collection bin 10 moves along the card moving path to the detection area detected by the shooting sensor 21, the camera module is triggered to shoot. Specifically, the shooting sensor 21 can be one of the sensors that can detect the card, such as an infrared sensor, a photoelectric sensor 410, etc.; it should be noted that when the card at the bottom of the card collection bin 10 moves to the position where the identification mark just leaks out and the camera area of ​​the camera module is aligned with the mark, the installation position of the shooting sensor 21 is obtained. The specific position setting of the shooting sensor 21 is related to the position of the hollow area 11 and the camera module. It can be understood that as long as it can be ensured that the card passes through the detection area of ​​the shooting sensor 21 to trigger the camera module to shoot, the identification mark can be photographed through the hollow area 11. Those skilled in the art can correct the position through continuous experiments, and no further details will be given here.

[0109] Among them, combined Figure 8 In some embodiments, the moving device includes a first motor 12 and a first synchronous belt 13 driven by the first motor 12, and the first synchronous belt 13 is arranged below the card collection bin 10, and the cards at the bottom of the card collection bin 10 are in contact with the first synchronous belt 13. When the first motor 12 drives the first synchronous belt 13 to move, the first synchronous belt 13 relies on friction to move the cards at the bottom of the card collection bin 10 out of the card collection bin 10 one by one, and the width of the first synchronous belt 13 is smaller than the width of the cards. It should be noted that because the cards at the bottom of the card collection bin 10 not only need to be transmitted, but also need to leak out marks so that the card recognition device 2 can collect images, the width of the first synchronous belt 13 must not be greater than the width of the cards to prevent the first synchronous belt 13 from completely covering the identification marks of the cards.

[0110] Combination Figure 3 , Figure 4 , Figure 5 and Figure 6 In some embodiments, the mobile device includes a second motor 14, a second synchronous belt 15, a first roller 16, a deceleration synchronous belt 17 and a second roller 18. The second motor 14 drives the second roller 18 to rotate through the second synchronous belt 15, and the second roller 18 drives the first roller 16 to rotate through the deceleration synchronous belt 17. The cards at the bottom of the card collection bin 10 are transmitted to the outlet of the mobile device through the first roller 16 and the second roller 18 in sequence. The ratio of the linear velocity of the first roller 16 to the linear velocity of the second roller 18 is 1:2.

[0111] Furthermore, the second motor 14 includes a driving axle, the first roller 16 includes a driven axle, the second roller 18 includes a driven axle and a driving axle, the driving axle 19 of the second motor 14 is drivingly connected to the driven axle 111 of the second roller 18 through the second synchronous belt 15, the driving axle 112 of the second roller 18 is drivingly connected to the driven axle 110 of the first roller 16 through the reduction synchronous belt 17, the wheel radii of the driving axle 19 of the second motor 14, the driven axle 110 of the first roller 16 and the driven axle 111 of the second roller 18 are all equal, and the ratio of the wheel radius of the driving axle 112 of the second roller 18 to the wheel radius of the driven axle 110 of the first roller 16 is 1:2.

[0112] It should be noted that the two rollers are designed with a speed difference, which accelerates the cards out of the exit and increases the distance between the cards and the next card, thereby further preventing the phenomenon of two playing cards being delivered to the exit at the same time.

[0113] Combination Figure 1 , Figure 2 and Figure 7 In some embodiments, the bottom surface of the card collection bin 10 is inclined, and the card collection mechanism 1 further includes a card pressing plate 115, which is used to press the cards in the card collection bin 10 so that the cards to be sent out from the card collection bin remain in close contact with the mobile device. The pressing force of the card pressing plate 115 can ensure that all the cards in the card collection bin 10 are pressed smoothly so that the cards to be sent out from the card collection bin remain in close contact with the mobile device, so that the mobile device can send out the cards one by one through friction.

[0114] In some embodiments, the card pressing plate 115 is rotatably disposed along a rotating axis on one side of the top of the card collecting bin 10. When it is necessary to collect cards, the card pressing plate 115 is rotated to open the card inlet of the card collecting bin 10. After the collection is completed, the card pressing plate 115 is rotated so that the card pressing plate 115 applies a downward pressure due to gravity from the top of the collecting bin to compact the cards in the card collecting bin 10.

[0115] Combination Figure 7 In some embodiments, an L-shaped card stopper 113 is provided in the card collection bin 10, and the L-shaped card stopper 113 includes a vertical portion and a horizontal portion. The vertical portion cooperates with the inner wall of the card collection bin 10 to form a card accommodating bin, and the vertical portion blocks the cards other than the cards to be output from moving along the moving direction of the cards to be output. The horizontal portion cooperates with the top tangent of at least one roller to form a limit outlet, and the limit outlet is limited to only one card passing through, further solving the problem of failure caused by the joint output of cards.

[0116] Combination Figure 3In some embodiments, in order to detect and solve faults occurring during the card transmission process, the card collection mechanism 1 further includes a card position sensor 114, which is disposed on the card output path of the mobile device, and is used to detect the ejection position of the card at the bottom of the card collection bin 10, and send the information of the ejection position of the card at the bottom of the card collection bin 10 to the controller; in actual use, the card position sensor 114 is used to detect faults in the process of inserting cards from the card collection bin 10 into the card buffer mechanism 3 (fault forms include cards not being delivered in place or not being delivered, and causes of faults include card deformation or missing corners). When a card insertion fault occurs, the first motor 12 drives the mobile device to withdraw the card and then reinsert it. Multiple failures will report a fault, which can be solved by manual card replacement.

[0117] Next, combine Figure 1 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 and Fig.13 , specifically introduce the card cache mechanism 3:

[0118] First, combine Figure 1 , Fig.12 and Fig.13 First, the card units in the card buffer mechanism 3 and the card slots under the card units are described. In one embodiment, based on the rules of the egg-throwing card game, the card units in the buffer mechanism are 4, and each card unit has 27 card slots. Fig.12 and Fig.13 , the four card units are card unit A, card unit B, card unit C and card unit D from bottom to top, where all the card slots under card unit A are A1, A2, A3...A27 from bottom to top, and so on, all the card slots under card unit B are B1 to B27 from bottom to top, all the card slots under card unit C are C1 to C27 from bottom to top, and all the card slots under card unit D are D1 to D27 from bottom to top, then, the card slots under each card unit are sorted from small to large according to the points from bottom to top. To the largest sort, and then sort by suit from diamonds, clubs, hearts, spades to define the corresponding cards to be received. For example, after definition, the card slot A1 under the card unit A corresponds to receiving diamond 3, A2 corresponds to receiving club 3, A3 corresponds to receiving spades 4, A4 corresponds to receiving hearts 7... and so on. These defined actions are generated by the computer with random arrays matching the card points and suits, and then associated one by one with the card units and the card slots under the card units. The generation and association method of the random array will be described in detail in a card distribution method below.

[0119] In another embodiment, based on the rules of the Landlord card game, in addition to setting 17 card slots in the four card units A, B, C, and D as described above, 14 card slots A1, A2 ... A14; B1, B2 ... B14, C1, C2 ... C14, D1, D2 ... D14 can be set in the four card units A, B, C, and D respectively. Because under the rules of the Landlord card game, it is not necessary to care about the suit of the cards, so only 14 card slots need to be set to receive the points of 3, 4 ... J, Q, K, 1, 2, and King in sequence, and each card slot can receive at most To store 4 cards of the same rank, then, based on the rules of the Landlord card game, the card slots under each card unit are defined in order from bottom to top according to the rank size. For example, after definition, the card slot A1 under the card unit A corresponds to receiving the 3 of diamonds, A2 corresponds to receiving the 4 of clubs, A3 is empty, A4 corresponds to receiving the 5 of hearts... and so on. Three of the card units receive 17 cards each, and one of the card units receives 3 cards. The defined actions are generated by a computer with a random array and then associated one by one with the card units and the card slots under the card units. The association methods will be described in detail in a card distribution method below.

[0120] In some embodiments, a predetermined interval G is provided between each of the card units of the card buffer mechanism 3. The interval is set to facilitate distinguishing the card units when taking cards later.

[0121] In some embodiments, each of the card units in the card cache mechanism and the card slots under the card units can reciprocate vertically relative to the exit of the mobile device; it should be noted that the card collection mechanism 1 is relatively static, and in order to accommodate different cards entering different card slots, each of the card units can move vertically relative to the transmission exit. When the card recognition device 2 recognizes the suit and point information of the card at the bottom of the card collection bin 10, the controller will quickly move the card slot corresponding to the suit and point information to the exit to receive the card. The vertical movement method is more accurate, faster and easier to implement than other movement methods.

[0122] Combination Fig. 9 , Fig.10 , Fig.11 and Fig.12In some embodiments, the card cache mechanism 3 further includes a third motor 31, and the card unit includes a cache rack 32 composed of a top plate and two side plates fixedly connected to the top plate and arranged opposite to each other. The third motor 31 drives the cache rack 32 to move in a straight line, and M card units are vertically distributed on the opposite inner sides of the two side plates in the cache rack 32, and each of the card units includes N vertically distributed card slots. According to the movement mode of each of the card units in the above-mentioned card cache mechanism, the arrangement mode of each of the card units in the card cache mechanism is matched.

[0123] In some embodiments, a first drive block 33 is fixedly provided on the outer side of one of the two side panels, and the first drive block 33 is detachably sleeved on a straight section of a third synchronous belt 34. The third motor 31 drives the third synchronous belt 34 to reciprocate, thereby driving the card unit to reciprocate vertically along a straight line.

[0124] In some embodiments, a first guide rail 35 is provided in parallel to one side of the straight section of the third synchronous belt 34, the first driving block 33 is slidably connected to the first guide rail 35, and each of the card units in the card cache mechanism performs vertical reciprocating motion along the first guide rail 35. The setting of the first guide rail 35 can calibrate the moving path of the cache rack 32, so that the movement of the cache rack 32 under the control of the third motor 31 is more precise.

[0125] In some embodiments, the card cache mechanism 3 also includes a first positioning sensor 36, which is used to detect the position of a predetermined card unit and send the position information of the predetermined card unit to the controller. The positioning sensor can also allow the card cache mechanism 3 to perform self-check and reset before inserting cards, further improving the movement accuracy of the cache rack 32 under the control of the third motor 31.

[0126] In some embodiments, the card buffer mechanism 3 further includes a card blocker for limiting the position of the cards entering the card unit to prevent the risk of subsequent card bending caused by the cards protruding relative to the card slot after insertion.

[0127] In some embodiments, the card blocker may be a baffle fixedly disposed on the other side of the buffer rack 32 opposite to the card entry side, and is used to limit the playing cards entering the card positions.

[0128] In some embodiments, the card buffer mechanism 3 further includes a rebound limiter for limiting the position of the cards entering the card unit to prevent the risk of the cards being bent due to the cards rebounding after insertion and protruding relative to the card slot.

[0129] In some embodiments, the rebound limiter can be an elastic member disposed on one of the two side panels, used to apply lateral force to clamp the playing cards entering the cache rack 32.

[0130] In some embodiments, the rebound limiter can be a barb member provided on the card entry side of the card rack, for limiting the position of the playing cards after entering the card rack.

[0131] Next, combine Fig.14 , Fig.15 , Fig.16 and Fig.17 , the card output mechanism is described in detail, and the card output mechanism includes:

[0132] The card box 41 is used to hold the cards in all the N card slots under each of the card units.

[0133] A card taking device, used for taking out cards from all N card slots in each of the card units one by one in order;

[0134] The turntable 411 device is used to carry the card shoe 41 and move the card shoe 41 to a designated position on the card table.

[0135] Combination Fig.15 In some embodiments, the card retrieval device includes a card dialer 42 and a power assembly driving the card dialer 42, the power assembly drives the card dialer 42 to move back and forth in a straight line, the moving path of the card dialer 42 is perpendicular to the moving path of the card unit and the card slot under the card unit, the card unit and the card slot under the card unit are arranged above the moving path of the card dialer 42, when the card dialer 42 moves along the moving path to the card unit and the bottom of the card unit, an upper folding part of the card dialer 42 moves the card unit and all the cards under the card unit to remove the card unit and send it to the card box 41.

[0136] It should be noted that the card puller 42 takes the cards from all the card slots under each card unit from bottom to top in sequence, with the card unit as a portion. In actual use, after each card unit receives the designated cards, it moves to the top, and the card puller 42 moves toward the card unit to the top so that the card puller 42 is directly below the card unit. The card unit is then moved downward by a predetermined distance so that the upper folding portion 43 of the card puller 42 is aligned with all the card slots under the lowest card unit. The card puller 42 is then driven to move toward the card box 41 to take out the card unit and all the cards under the card unit and send them to the card box 41, and so on, until all the cards in the N card units are taken out and sent to the card box 41.

[0137] Combination Figure 1 , Fig. 9 and Fig.15 In some embodiments, the card pusher 42 can also be used as the card blocker. Specifically, when the cache mechanism feeds cards, the card pusher 42 moves toward the card cache mechanism 3 until the upper folding portion 43 of the card pusher 42 reaches the end surface of the card slot on the other side opposite to the card feeding side.

[0138] In some embodiments, when the card remover 42 removes cards, the card unit to be removed moves until the lowest card under the card unit is completely in contact with the bearing surface 44 of the card remover 42 .

[0139] In some embodiments, the card box 41 is arranged at the other end of the moving path of the card picker 42 relative to one end of the card unit, and the card box 41 and the card picker 42 are offset up and down. When the card picker 42 takes a piece of cards from the card unit, it is transferred to the card box 41 for offset separation so that the cards fall into the card box 41.

[0140] Combination Fig.15 and Fig.16 In some embodiments, an end of the card box 41 close to the card dial 42 extends with an oblique guide foot 45 toward the bearing surface 44 of the card dial 42, and the extended end of the oblique guide foot 45 is located below the bearing surface 44 of the card dial 42 and forms an angle with the bearing surface 44 of the card dial 42. When the card dial 42 carries a card close to the card box 41, the bottom surface of the card contacts the oblique guide foot 45, and the card is separated from the bearing surface 44 of the card dial 42 along the guidance of the oblique guide foot 45 and is continuously pushed into the card box 41 by the upper folding portion.

[0141] Combination Fig. 9 In some embodiments, the card cache mechanism 3 also includes an arched card protector 37, which is fixedly disposed on the card moving path between the card cache mechanism 3 and the card output mechanism 4, and is used to prevent the cards from shaking left and right during the process of being taken out of the card cache mechanism 3 by the card output mechanism 4.

[0142] See also Fig.15 In some embodiments, the power assembly includes a fourth synchronous belt 46, a fourth motor 47 that drives the fourth synchronous belt 46 to move, and a second guide rail 48 that is parallel to the moving path of the card dialer 42. The card dialer 42 is slidably mounted on the second guide rail 48 through a second driving block 49. The card dialer 42 can also be detachably mounted on the fourth synchronous belt 46. When the fourth motor 47 drives the fourth synchronous belt 46 to move, it further drives the card dialer 42 to reciprocate along the second guide rail 48. The setting of the second guide rail 48 can calibrate the moving path of the card dialer 42, so that the movement of the card dialer 42 under the control of the fourth motor 47 is more precise.

[0143] In some embodiments, a photoelectric sensor 410 is provided on the moving path of the card pusher 42 for self-checking and resetting the card pusher 42 .

[0144] See also Fig.14 In some embodiments, the turntable 411 device includes a turntable 411 and a fifth motor 412 for driving the turntable 411 to rotate. Several card boxes 41 are fixedly installed on the turntable 411 at predetermined intervals. The fifth motor 412 drives the turntable 411 to rotate and moves the card boxes 41 one by one to the card retrieval position for retrieval.

[0145] In some implementations, the turntable 411 device further includes a positioner for positioning the turntable 411 or the card box 41. In this embodiment, the position of the card box 41 on the turntable 411 is also the player's position.

[0146] In some embodiments, the side of the card box 41 that receives the cards is tilted upward relative to the horizontal plane, and the card bearing surface of the card box 41 forms a predetermined angle with the horizontal plane. The inclined bearing surface design of the card box 41 can prevent the cards from falling off when the card box 41 and the turntable 411 device rotate.

[0147] The second embodiment of the utility model also provides a card distribution system, which includes:

[0148] The card collection mechanism comprises a card collection bin and a moving device located below the card collection bin, wherein the card collection bin is used to collect a preset number of cards that are arranged in an unordered manner, and the moving device is used to move the cards to be issued from the card collection bin one by one.

[0149] A playing card recognition device, used to recognize the suit and point information of the playing cards to be issued from the playing card collection bin;

[0150] The card buffer mechanism comprises at least M card units distributed along the same straight line, each card unit comprises N card slots distributed along the same straight line, and the card slots are used to sequentially match and receive cards to be issued from the card collection bin moved by the moving device;

[0151] A card output mechanism, used to sequentially receive cards from all N card slots in any one of the card units, and transfer the received cards to a designated position on the card table;

[0152] The controller is used to determine the card unit corresponding to the card to be issued from the card collection bin and the card slot under the card unit according to the suit and point information of the card to be issued from the card collection bin identified by the card recognition device, and control the card cache mechanism to move the card slot under the card unit to the exit of the moving device in the card collection mechanism. It should be noted that the controller stores the serial number and corresponding position of each card unit and the card slot under the card unit.

[0153] The second embodiment is different from the first embodiment in that each of the card units in the card cache mechanism is horizontally distributed along the same straight line, and the card slots under each card unit are vertically distributed along the same straight line. When the card cache mechanism receives cards: after the controller confirms the points and / or suit of the cards to be received, it controls the card units of the card cache mechanism to move horizontally along the straight line until the designated card unit that needs to receive the cards moves to the card outlet of the mobile device, and then controls the designated card unit to move vertically along the straight line until the designated card slot under the designated card unit is aligned with the card outlet of the mobile device; when the card cache mechanism outputs cards, the controller controls the card retrieval device under the card output mechanism to move to the designated position below the card cache mechanism, and then controls the card unit under the card cache mechanism that needs to output cards to move to cooperate with the card retrieval device, and then the card retrieval device takes away all the cards under the card unit. It can be understood that the mechanical connection relationship between all the card units can be a rigid connection driven by the same motor to achieve simultaneous horizontal movement, and each card unit can be a rigid connection driven by the same motor to achieve simultaneous vertical movement, or each card unit can be driven by a motor to achieve independent vertical movement.

[0154] The above is an introduction to a playing card distribution system provided by the present invention.

[0155] Next, combine Fig.17 , introduces a playing card distribution method applied to the playing card distribution system of the utility model:

[0156] S100, based on the number of players and the current game mode, generate K groups of random arrays, each group of the random arrays includes L elements, and the elements of each group of the random arrays are associated with the points and / or suits of playing cards;

[0157] It should be noted that this method first initializes the array based on the number of players and the current game mode, that is, first confirm the number of players and the current game mode, so as to confirm the points, suits, and quantity of the cards to be used, and then confirm all the elements of the array based on the required cards. For example, based on the rules of the Pai Gow card game, there can be 4 players, each with 27 cards, and all the cards of all points and suits consist of two decks of cards, totaling 108 cards. Then, during initialization, first define that there are 108 elements in the array, and the elements under the array include, in order: 0, 0, 1, 1, 2, 2, 3, 3, ... 52, 52, 53, 53; after determining the array and all the elements under the array, all the elements are bound to the card points and suits one by one, such as binding the elements under the array The first and second elements "0" are bound to the cards with a point value of 1 and a suit of diamonds. The third and fourth elements "1" in the array are bound to the cards with a point value of 2 and a suit of diamonds. This continues until the twenty-fifth and twenty-sixth elements "12" in the array are bound to the cards with a point value of K and a suit of diamonds. At this point, all cards with a suit of diamonds have been bound to the elements in the array. This continues until the twenty-seventh and twenty-eighth elements in the array are bound to the twenty-seventh and twenty-eighth elements in the array. The fifty-first element and the fifty-second element, i.e., "13" to "25", are bound in sequence to the cards of all points under the suit of clubs; the fifty-third element and the fifty-fourth element to the seventy-seventh element and the seventy-eighth element, i.e., "26" to "38", are bound in sequence to the cards of all points under the suit of hearts; the seventy-ninth element and the eightieth element to the one hundred and third element and the one hundred and fourth element, i.e., "39" to "51", are bound in sequence to the cards of all points under the suit of spades; the one hundred and fifth element and the one hundred and sixth element, i.e., "52", are bound to the little king; the one hundred and seventh element and the one hundred and eighth element, i.e., "53", are bound to the big king; at this point, the association and binding of all elements in the array with all cards is completed; then, the four groups of random arrays are generated based on the 108 elements bound to the card points and suits, wherein each group of random arrays has 27 elements.

[0158] It is understandable that random arrays can also be generated according to other rules. For example, in the Landlord card game, a deck of cards is used with a total of 54 cards. The 54 cards are divided into 3 players' hands and a set of spare cards, where each player has 17 cards and 3 spare cards. Then 4 groups of random arrays are generated, 3 of which have 17 elements and 1 of which has 3 elements.

[0159] It should also be noted that the random array is generated by a computer based on an array of defined elements in a disordered manner, and the options for the number of players and the game mode can be pre-set and stored in the PLC module of the card distribution device for players to switch and select when using.

[0160] In some specific embodiments, the random array can be generated in two ways. One is to directly generate N random arrays and then sort the random arrays according to the card point size and the card suit, or directly generate an ordered random array sorted by the card point size and the card suit. The other is to generate a random array, divide the random array into N groups, and then sort the random array, and regenerate the random array after each card distribution.

[0161] S200, respectively associating each group of the random arrays with a card unit in a card buffer mechanism that can move along a straight line, and associating the elements in each group of the random arrays with a card slot in a corresponding card unit;

[0162] It should be noted that the association method can be explained as follows: based on the above-mentioned rules of the egg-throwing game, four groups of random arrays N1, N2, N3, and N4 are generated, each of which has 27 elements. The random arrays N1, N2, N3, and N4 are associated with the card units A, B, C, and D respectively, and the elements in the random array N1 are bound to the card slots A1, A2, A3, ... A27 under the card unit A in sequence. In the specific implementation, if the first element of the random array N1 is "2", it means that the corresponding bound card slots A1, A2, A3, ... A27 are bound to the card slots A1, A2, A3, ... A27 under the card unit A. The second element is "15", which represents the corresponding bound card "3 of clubs", the third element is "42", which represents the corresponding bound card "4 of spades", and the fourth element is "32", which represents the corresponding bound card "7 of hearts". Then the card slot A1 under the card unit A corresponds to receiving the 3 of diamonds, A2 corresponds to receiving the 3 of clubs, A3 corresponds to receiving the 4 of spades, A4 corresponds to receiving the 7 of hearts... and so on, until all the card slots under the card units B, C, and D are linked, and re-linked after each game.

[0163] Alternatively, when the card slot only receives cards according to the points, it can be set that the card slot can receive multiple cards. First, the card slot A1 under the card unit A is bound to the elements "0", "13", "26", and "39", which means that the card slot A1 only receives cards with a point of 1. The card slot A1 under the card unit A is bound to the elements "1", "14", "27", and "40", which means that the card slot A2 only receives cards with a point of 2... The card slot A2 under the card unit A is bound to the elements "1", "14", "27", and "40", which means that the card slot A2 only receives cards with a point of 2. Slot A13 is bound to elements "12", "25", "38", and "57", which means that card slot A13 only accepts cards with a point value of K. Similarly, all card slots under all card units B, C, and D are defined. Then, according to the computer's random array, each card slot is associated with the number of elements associated with each card slot. Empty slots are allowed. When all card slots under each card unit are associated with a total of 27 cards, the association ends and the association is re-performed after each game is completed.

[0164] S300, obtaining the points and suit of the cards to be distributed identified by the card recognition device, and determining the card units and card slots in the card buffer mechanism into which the distributed cards enter based on the points and / or suit of the cards.

[0165] It should be noted that, based on the points and suit of the cards to be distributed identified by the card recognition device, the specific element to which the card is bound is confirmed, and the card unit and card slot that the card enters are confirmed based on the random array where the specific element is located and the specific element.

[0166] S400, controlling the movement of the card cache unit so that the card units and card slots in the card cache mechanism corresponding to the distributed cards move to the card outlet aligned with the card collection mechanism, and the cards in all the card slots under each group of the card units are arranged according to a preset rule.

[0167] It should be noted that the PLC module of the card distributing device stores the position of each card unit in the cache mechanism and each card slot under each card unit, as well as the position of the card outlet of the card collecting mechanism.

[0168] It should also be noted that the cards in all the card slots under each group of the card units are arranged in order from large to small or from small to large according to points and / or suits, specifically including two situations:

[0169] In one case, when each card slot under each card unit only receives one card, it is necessary to sort the elements in each group of random arrays by points and / or suits, and then bind all the ordered random arrays after sorting to the card units one by one, and bind the elements under each group of ordered random arrays to the card slots under the card units one by one in order. The sorting method in this case can be: sorting the suit of each card according to the size of the element value, and sorting the points of each card according to the remainder of the value divided by 13.

[0170] Another situation is that when each card slot under each card unit can receive multiple cards, it is necessary to first define the cards that each card slot receives in order according to the points and / or suits, bind each group of random arrays to the card unit, and calculate the number of each element of the random array corresponding to the card unit. The number of elements is the number of cards that each card slot needs to receive.

[0171] S500: Based on the association between each group of the card units and the players, the cards in all the card slots in the card units are transported to the corresponding player areas. Specifically, based on the correspondence between the serial number of each card unit and the serial number of the player, the cards in all the card slots in the card units are transported to the corresponding player areas.

[0172] Finally, a card dispensing device provided by the utility model is introduced, wherein the card dispensing device comprises a processor and a memory coupled to the processor;

[0173] The memory is used to store a computer program, and the processor is used to execute the computer program to implement the following playing card distribution method:

[0174] S100, generating K groups of random arrays based on the number of players and the current game mode, wherein the elements of each group of random arrays are associated with the points and / or suits of playing cards;

[0175] S200, respectively associating each group of the random arrays with a card unit in a card buffer mechanism that can move along a straight line, and associating the elements in each group of the random arrays with a card slot in a corresponding card unit;

[0176] S300, obtaining the points and suit of the cards to be distributed identified by the card recognition device, and determining the card units and card slots in the card buffer mechanism into which the distributed cards enter based on the points and / or suit of the cards.

[0177] S400, controlling the movement of the card cache unit so that the card slots under the card units in the card cache mechanism corresponding to the cards to be distributed move to the card outlet aligned with the card collection mechanism, and the cards in all the card slots under each group of the card units are arranged according to a preset rule.

[0178] S500: Based on the association relationship between each group of the playing card units and the players, transport the playing cards in all the playing card slots in the playing card units to the corresponding player areas.

[0179] The utility model collects disorderly arranged cards based on the card collection bin of the card collection mechanism, and then outputs the cards in the card collection bin one by one through the moving device of the card collection mechanism. At the same time of output, the card recognition device is combined to identify the suit and point information of the cards to be issued from the card collection bin to be output, and then the controller controls the pre-set card buffer mechanism to move to correspondingly receive the cards to be issued from the card collection bin. The pre-set card buffer mechanism corresponds to the cards that each card slot under each card unit should receive, and What is different from the prior art is that each card slot under each card unit is sorted based on rules, that is, after all the card slots under all the card units have received all the cards, all the cards in each card unit have been sorted from top to bottom or from bottom to top based on suit and / or points, and can be sent directly to the player, thereby speeding up the game efficiency and improving the player experience. In addition, the card recognition device and the card cache mechanism can be combined to check the integrity of the points, suit and number of cards to prevent missing cards or duplicate cards in the game.

[0180] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
