Description

Technical Field

[0001] The invention relates to the field of poker machines, and in particular to a poker machine and a card dealer, a card storage box and a poker card sorting method 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 also has the disadvantage of playing cards being 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. In addition, the poker machine has a loose structure, a large volume, and a low installation efficiency.

[0011] Patent documents such as publication number CN110787444A disclose a poker machine, comprising: a card feeding device for inserting playing cards, the card feeding device comprising a panel fixed on the top of the base, a control disk arranged in the center of the panel, the control disk being driven up and down by a central lifting mechanism, a card placing opening for inserting playing cards being formed below the control disk when the control disk is raised, and the card placing opening being covered when the control disk is lowered; a card sorting device for arranging playing cards into a uniform orientation and sending them out, the card sorting device being located below the control disk, the card sorting device comprising a card sorting seat fixed on the base, a central turntable driven to rotate by a turntable motor arranged in the center of the card sorting seat, an outer wall of a card sorting channel arranged around the card sorting seat, an arcuate card sorting channel for arranging playing cards being formed between the central turntable and the outer wall of the card sorting channel, a plurality of conveying rollers for conveying playing cards being arranged at the bottom of the arcuate card sorting channel, a card sorting channel outlet being arranged at one end of the arcuate card sorting channel for allowing playing cards to be sent out along its length direction; wherein, The width of the card sorting channel is less than the length of the playing cards and greater than the width of the playing cards, the distance between two adjacent conveying rollers is less than the length of the playing cards, and the width of the exit of the card sorting channel is close to the width of the playing cards; a card distributor for sending the playing cards one by one to the card receiving device, the card distributor is fixed on a base and is located below the card sorting seat, the card distributor includes a card storage box and a card issuing device, the upper opening of the card storage box is located below the exit of the card sorting channel, and one side of the bottom of the card storage box is connected to the card feeding channel of the card issuing device; the card issuing device includes a card separating mechanism for separating the playing cards in the card storage box into pieces and sending them to the conveying mechanism, a conveying mechanism for identifying the front and back sides of the playing cards and conveying the playing cards to the card flipping mechanism, and a card flipping mechanism for flipping the playing cards as needed and sending the playing cards to the card receiving device; a card receiving device for receiving the playing cards, the card receiving device includes a plurality of card receiving boxes arranged around the card distributor, and these card receiving boxes are driven to rotate relative to the card distributor by a rotating driving mechanism. However, in this structure, the playing cards are sent into the card storage box one by one from the exit of the card sorting channel, and the space inside the card storage box is relatively large. The height difference between the exit of the card sorting channel and the bottom of the card storage box is large. The playing cards in the card storage box are easy to float or be placed in the air, which results in the playing cards not being able to quickly and reliably enter the card dealing device, affecting the efficiency of card dealing and even causing malfunctions.

[0058] like Figure 1 , Figure 2 , Fig.11 , Fig.12 , Fig. 20 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.

[0059] like Figure 1 , Figure 2 As shown, 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 it 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. As Fig.12 As shown, in other embodiments, the base 1 may also be plate-shaped or disc-shaped.

[0060] About the card sorting device.

[0061] like Figure 5 , Figure 6 and Figure 7As 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 placing port are rotated and moved into the arc-shaped card sorting channel by the central turntable 606, and 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, and 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 of the playing cards 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 the width direction and sending them forward to realize the 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.

[0062] like Figure 5 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] In this embodiment, an upper shell 601 for covering the central turntable 606 and the upper part of the card sorting channel is fixed above the card sorting seat 602, so that the card sorting 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 sorting. Of course, in other embodiments, a shell for covering the card sorting seat 602 and the transmission components thereon can also be set on the side or bottom of the card sorting seat 602.

[0067] 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.

[0068] In this embodiment, the card sorting device adopts a central card feeding method similar to that of a mahjong machine. A panel 3 is provided on the top of the base 1. 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. When the control panel 303 is lowered, the card placement opening is covered. The card sorting device 6 is installed below the control panel 303.

[0069] 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.

[0070] In this embodiment, Figure 7 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.

[0071] 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.

[0072] 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.

[0073] 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. It generally includes a card-discharging active roller wheel and a pressure roller driven by a card-discharging motor. Accordingly, the above-mentioned card-discharging mechanism can be installed on the card-discharging baffle 607, or on the card-discharging seat 502 or the upper shell 601.

[0074] In this embodiment, Fig.15 As shown, the card discharging mechanism includes a card discharging active wheel 6075 and a pressure wheel 6076, wherein the card discharging active wheel 6075 is mounted on the card discharging seat 602 and driven to rotate by a motor, and the pressure wheel 6076 is mounted on the free end of a pressure wheel bracket 6077, and the movable connection end of the pressure wheel bracket 6077 is mounted on the card discharging baffle 607, the card discharging seat 502 or the upper shell 601 and is given a downward rotation tendency by a torsion spring 6078, so that the pressure wheel 6076 is close to the card discharging active wheel 6075. A preferred embodiment is that the card discharging active wheel 6075 is also connected to the bottom gear transmission of the outer side wall 603 of the card discharging channel through an outer gear 6051, and is driven by an outer motor 604 together with the conveying roller 605, so that the structure is simple, reliable and low in cost. The enabling mechanism of the pressure wheel 6076 can also be a compression spring, an elastic sheet or other various structures.

[0075] In order to prevent a large number of playing cards from concentrating through the card handling channel outlet 610 and causing a blockage, a card discharging control mechanism is also installed at the card handling channel outlet 610, and the card discharging control mechanism includes a control wheel 6074 for controlling the number of playing cards entering the card handling channel outlet 610 by actively rotating, and the control wheel 6074 is located above the card handling channel outlet 610 and forms a gap greater than the thickness of a playing card between the bottom wall of the card handling channel and the conveying roller 605 so that at least one playing card can be delivered without being affected. In addition, it is preferred that the control wheel 6074 is located between the card discharging baffle 607 and the conveying roller 605, or the control wheel 6074 is located between the card discharging baffle 607 and the card discharging mechanism. When too many stacked playing cards are squeezed into the card sorting channel exit 610, the control wheel 6074 rotates in the direction of preventing the playing cards from entering the card sorting channel exit 610, thereby withdrawing the excess playing cards from the card sorting channel exit 610, thereby limiting the number of playing cards (3 to 8 playing cards) entering the card sorting channel exit 610 at the same time to avoid blockage; when the number of playing cards entering the card sorting channel exit 610 at the same time does not exceed the predetermined number, it is not affected by the control wheel 6074, and the conveying roller 605 on the bottom wall of the card sorting channel or the card-discharging mechanism drives the playing cards through the card sorting channel exit 610.

[0076] In a preferred embodiment, the rotation and conveying direction of the control wheel 6074 is opposite to the rotation and conveying direction of the conveying roller 605, so as to facilitate installation, debugging and control. It should be noted that the "rotation and conveying direction" here refers to the direction in which the playing cards in contact with the control wheel 6074 or the conveying roller 605 move after the control wheel 6074 or the conveying roller 605 rotates, rather than the rotation direction of the control wheel 6074 or the conveying roller 605.

[0077] In a preferred embodiment, the control wheel 6074 is driven by an independent control wheel motor 6071, so that according to the actual needs, the control wheel 6074 can be controlled to rotate or not rotate, and the conveying speed of the control wheel 6074 can also be adjusted to achieve high efficiency and low failure rate of cards from the card handling channel outlet 610. In other embodiments, the control wheel 6074 can also be connected to the driving motor of the conveying roller 605 or the card discharging mechanism through a transmission mechanism. In this embodiment, a further preferred mode is that the control wheel motor 6071 is a forward and reverse motor, so that when the playing cards in the card handling channel are less or floated, the control wheel motor 6071 can drive the control wheel 6074 to rotate and convey in the same direction as the conveying direction of the conveying roller 605, thereby facilitating the playing cards to quickly enter the card handling channel outlet 610.

[0078] like Fig.15As shown, in this embodiment, the control wheel 6074 and the control wheel motor 6071 are installed on one side outside the card sorting channel of the card output baffle 607, and a part of the control wheel 6074 passes through one side inside the card sorting channel of the card output baffle 607, so that the contact circumference of the control wheel 6074 and the playing cards is larger, and the guiding and controlling effect of the playing cards is better.

[0079] In this embodiment, it is further preferred that the control wheel motor 6071 is located above the control wheel 6074, and the two are connected by gear A6072 and gear B6073. This has a compact and reasonable structure, reliable and accurate transmission, and is easy to install. Of course, in other embodiments, the two can also be connected by a synchronous belt or chain.

[0080] In this embodiment, it is further preferred that two conveying rollers 605 are arranged front and rear on the bottom wall of the card sorting channel below the control wheel 6074, and the control wheel 6074 is located between the two conveying rollers 605 below it, and the gap between the control wheel 6074 and the two conveying rollers 605 is larger than the thickness of a playing card and smaller than the thickness of ten playing cards, thereby achieving a better guiding and controlling effect on the playing cards.

[0081] like Figure 1 , Figure 2 In one embodiment shown, the card handling device 6 is directly fixed on the base 1 and is located above the card dealer. In such an arrangement, if the card dealer needs to be installed and repaired, the card handling device must be removed. There are many power lines and signal lines on the card handling device 6 connected to the power supply and controller on the base, which makes disassembly, installation, debugging and maintenance cumbersome and troublesome.

[0082] Therefore, it is preferred that Fig.12 , Fig.13 , Fig.14 In another embodiment shown, one end of the card handling device 6 is hinged to the base 1 through a hinge structure, so that the other end of the card handling device 6 can be flipped up to facilitate installation, commissioning and maintenance. When the card handling device 6 is flipped down, it is fixed to the base 1 through a positioning member and / or a fastener and mounted above the card dealer 40 to ensure accurate positioning and matching of the card handling device 6 and the card dealer 40. Further preferably, Fig.13 The positioning member is a plurality of positioning support columns 6023 fixed on both sides of the card dealer on the base 1, and the top of the positioning support column 6023 is plugged and matched with the bottom of the card handling seat 602 of the card handling device 6 for positioning, so that the structure is simple and the positioning is reliable. Fig.14As shown, the hinged structure includes a mounting seat 6021 and a mounting bracket 6022, the mounting seat 6021 is fixed on the poker machine base 1, the mounting bracket 6022 is fixed on the bottom of the card handling seat 602, and one end of the mounting seat 6021 and the mounting bracket 6022 are hinged. Further preferably, a fixed limit 60211 is provided on the mounting seat 6021, and a movable limit 60221 is provided on the mounting bracket 6022. When the card handling device 6 is flipped up, the mounting bracket 6022 and the mounting seat 6021 are mutually limited by the fixed limit 60211 and the movable limit 60221 to achieve positioning when flipping up and opening. Further preferably, the mounting seat 6021 and the mounting bracket 6022 are both made of metal plates, and the fixed limit 60211 and the movable limit 60221 are two convex bending parts corresponding to each other.

[0083] About the card dealer.

[0084] The internal structure of the card distributor 40 is basically the same as that disclosed in patent documents such as CN209405643 and CN110193184, and the main difference is that in this embodiment, the conveying channel is extended to adapt to the setting of the card sorting 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:

[0085] like Fig. 9 , Fig.10 , Fig.11 , Fig.16 , Fig.17 , Fig.18 and Fig.19 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 rotating disk 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, operation processes and methods can adopt the structures, principles, operation processes and methods disclosed in the patent documents with publication numbers CN209405643, CN110193184 and other patent documents, as well as various alternative structures, principles, operation processes and methods disclosed in the patent documents with publication numbers CN209405643, CN110193184 and other patent documents, and the same contents will not be repeated.

[0086] Regarding the card storage box, based on the patent documents disclosed in publication numbers CN209405643, CN110193184, etc., in this embodiment, the height of the side walls of the card storage box 41 is reduced so that it can better cooperate with the card handling channel outlet 610 of the card handling device. The direction in which the card handling device 6 sends out the playing cards from the card handling channel outlet 610 is substantially perpendicular to the direction in which the playing cards in the card storage box 41 are sent out (at an angle of 90°±10°). Fig. 9 , Fig.10 and Fig.11 As shown, below one side wall of the card storage box 41 is the card outlet of the card storage box 41, and the card storage box 41 is connected with the card dividing mechanism of the card inlet channel of the card dealing device through the card outlet. One side wall of the card storage box 41 with the card outlet is the card outlet side wall 4101, and the other side wall of the card storage box 41 located below the exit 610 of the card handling channel is the card inlet side wall 4105. The card outlet side wall 4101 and the card inlet side wall 4105 are adjacent to each other, so that the spatial layout of the card dealing device and the card handling device is reasonable and the structure is compact.

[0087] In a preferred embodiment, a card blocking guide bracket 4103 is provided above the opening of the card storage box 41. The card blocking guide bracket 4103 is located on the opposite side of the card sorting channel outlet 610. The card blocking guide bracket 4103 has a guiding arc surface on the side facing the card sorting channel outlet 610 for promoting the playing cards to fall into the card storage box 41. The card blocking guide bracket 4103 can be in a columnar, plate-like or block-like structure. The card blocking guide bracket 4103 can be fixed on the opposite side of the card sorting channel outlet 610 of the card sorting seat 602. However, the card blocking guide bracket 4103 is more preferably fixed or integrally formed on the side wall of the card storage box 41, such as Fig.13 , Fig.16 , Fig.17 , Fig.18 and Fig.19 As shown, this improves the integration and makes manufacturing, installation and debugging more convenient.

[0088] In the prior art, playing cards are fed into the card storage box one by one from the exit of the card sorting channel, and the space inside the card storage box is relatively large, and the height difference between the exit of the card sorting channel and the bottom of the card storage box is relatively large. In order to prevent the playing cards in the card storage box 41 from floating or being suspended in the air, thereby causing the playing cards to be unable to quickly and reliably enter the card dealing device, it is preferred that a card pressing mechanism is provided on the card storage box 41:

[0089] like Fig.16 , Fig.17 , Fig.18 and Fig.19As shown, the card pressing mechanism includes a movable card pressing member 4102, which has at least two positions: in the first position, the card pressing member 4102 presses the playing cards in the card storage box 41 to the bottom of the card storage box 41 to ensure that the playing cards can be quickly and reliably delivered to the card dealing device by the card feeding wheel 4201; in the second position, the card pressing member 4102 leaves the bottom of the card storage box 41 and does not affect the delivery of the playing cards from the card sorting channel outlet 610 to the card storage box 41.

[0090] The above-mentioned card-pressing piece 4102 can be a rod-shaped or sheet-shaped part that rises and falls, or can be a swinging or rotating part that rotates in and out of the card storage box. A preferred embodiment is that one end of the above-mentioned card-pressing piece 4102 is hinged with a side wall of the card storage box 41, and the other end of the card-pressing piece 4102 swings up and down to implement card-pressing, which has a simple structure and is fast and effective in pressing cards. Further preferably, the card-pressing piece 4102 is driven to swing up and down by the card-pressing motor 4104 that is installed on the card storage box 41. Further preferably, the card-pressing part of the card-pressing piece 4102 is a reed with elasticity, which has good adaptability and strength, and can reduce the driving load and braking load of the motor, thereby reducing manufacturing costs. Further preferably, the card pressing member 4102 is hingedly arranged on a side wall of the card storage box 41 opposite to the card handling channel outlet 610 (a side wall opposite to the card feeding side wall 4105), or the card pressing member 4102 is hingedly arranged on a side wall of the card storage box 41 opposite to the card outlet of the card storage box 41 (a side wall opposite to the card outlet side wall 4101). Preferably, the card pressing position of the card pressing member 4102 in the card storage box 41 is close to the card outlet of the card storage box 41 (the card outlet side wall 4101), so as to avoid that the end of the playing cards near the card outlet after being pressed is tilted and cannot enter the card outlet. Further preferably, the card pressing position of the card pressing member 4102 in the card storage box 41 corresponds to the conveying position of at least one card delivery wheel 4201 up and down, so as to improve the card delivery efficiency and avoid that the playing cards are tilted and cannot enter the card outlet after being pressed. The card pressing action of the card pressing component 4102 can be controlled by the card pressing motor 4104 to perform regular intermittent movements, or the card pressing motor 4104 can control the card pressing component 4102 to perform corresponding actions based on the signal of a detection sensor arranged in the card storage box 41 or in the conveying channel of the card dealing device.

[0091] Regarding the card issuing device, based on the patent documents disclosed in publication numbers CN209405643, CN110193184, etc., this embodiment makes the following improvements:

[0092] 1. In the prior art, the card-splitting mechanism of the card-dealing device includes a card-blocking plate, a card-feeding wheel, a card-splitting wheel and a card-splitting pressure wheel. The card-splitting wheel for pushing playing cards to the card-feeding channel of the card-dealing device is installed at the bottom of the card storage box. The card-blocking plate serves as the card-discharging side wall of the card storage box. The card-splitting pressure wheel is arranged at the bottom of the card-blocking plate. The card-splitting pressure wheel is arranged below the card-splitting pressure wheel. The card-splitting wheel is driven by the card-dealing motor. The card-splitting pressure wheel can rotate when feeding cards but not when retiring cards through a one-way clutch mechanism. In addition, in order to further improve the card-splitting effect of the above-mentioned card-splitting mechanism, a plurality of card-feeding ridges are arranged at the bottom of the card-blocking plate. When playing cards are fed into the card storage box one by one from the exit of the card sorting channel, and the card inlet side wall and the card outlet side wall of the card storage box are adjacently arranged vertically, multiple card separation pressing wheels and card inlet ridges cause the surface of the card baffle plate serving as the card outlet side wall to be uneven, which can easily cause the playing cards to be chaotically suspended in the card storage box and unable to quickly enter the card outlet; when a large number of playing cards are forcibly pressed against the bottom of the card storage box or the card separation wheel by the card pressing mechanism, the playing cards will be damaged or the card outlet will be blocked.

[0093] Therefore, in the preferred implementation manner of this embodiment, Fig.18 , Fig.19 As shown, the card-splitting mechanism includes a card-feeding wheel 4201, a card-splitting wheel 4202 and a card-splitting pressure wheel 4221. The card-feeding wheel 4201 and the card-splitting wheel 4202 are both active wheels driven by a motor, and the card-splitting pressure wheel 4221 is a driven wheel. The card-feeding wheel 4201, which is used to push the playing cards to the card-input channel of the card-delivering device, is installed at the bottom of the card-splitting box 41. A card-discharging port is formed between the card-discharging side wall 4101 of the card-discharging box 41 and the bottom wall of the card-discharging box. The card-splitting wheel 4202 is rotatably installed on the card-discharging box 41 or the housing of the card-delivering device and is located at the card-discharging port of the card-discharging box 41. The card delivery wheel 4201 and the card dividing wheel 4202 are respectively located on the inner and outer sides of the card discharging side wall of the card storage box 41, and the card dividing pressure wheel 4221 is rotatably mounted on the movable part 4222, and the movable part 4222 is mounted on the fixed seat 4223 in a manner that it can move up and down. The fixed seat 4223 is fixed on the housing of the card storage box 41 or the card dealing device, and the movable part 4222 and the fixed seat 4223 are connected by an elastic part to give the card dividing pressure wheel 4221 a tendency to press toward the card dividing wheel 4202. The card discharging side wall of the card storage box 41 is no longer provided with uneven card discharging pressure wheels and card feeding ridges, and the surface is relatively smooth so that the playing cards will not be placed in the air. The playing cards sent into the card storage box one by one from the exit of the card sorting channel can fall smoothly on the bottom of the card storage box and be quickly sent into the card discharging port of the card storage box 41 by the card feeding wheel 4201. The card discharging wheel 4202 and the card discharging pressure wheel 4221 are arranged outside the card discharging port of the card storage box 41, which can have a good card discharging effect just like arranging them at the card discharging port of the card storage box 41 in the prior art.

[0094] In a preferred embodiment, a card-splitting cam 4203 is provided between the card-splitting pressure wheel 4221 and the card-discharging side wall of the card-splitting box. The card-splitting cam 4203 is rotatably mounted on the card-splitting box 41, the fixing seat 4223 or the housing of the card-delivering device. The card-splitting cam 4203 is located above the card-feeding channel of the card-delivering device. The card-splitting cam 4203 is a driving wheel driven by a motor. The rotation axis of the card-splitting cam 4203 is parallel to the rotation axis of the card-delivering wheel 4201 and the card-splitting wheel 4202. The rotation direction of the card-splitting cam 4203 is consistent with the rotation direction of the card-delivering wheel 4201 and the card-splitting wheel 4202. In this way, the card-splitting cam 4203 can not only be filled between the card-splitting pressure wheel 4221 and the card-discharging side wall of the card-splitting box to avoid playing cards from being stuck in the gap, but also can push the redundant playing cards above out of the card-feeding channel of the card-delivering device, thereby limiting the number of playing cards entering and achieving the effect of pre-splitting.

[0095] Further preferably, the card separating cam 4203 and the card feeding wheel 4201 and the card separating wheel 4202 are respectively connected by synchronous belt transmission to achieve synchronous rotation.

[0096] Further preferably, a plurality of card-feeding ridges are provided on the fixed seat 4223, and the card-feeding ridges are located between the card-splitting cam 4203 and the card-splitting pressure wheel 4221, and the card-feeding ridges, the card-splitting cam 4203 and the card-splitting pressure wheel 4221 are arranged in staggered intervals, so that a continuous and efficient card-shuffling and separation effect can be achieved.

[0097] Further preferably, a plurality of card-feeding projections are formed on the inner wall at the bottom of the card storage box 41 between the card-delivering wheel 4201 and the card-distributing wheel 4202, and the card-feeding projections are arranged in coordination with the card-distributing cam 4203. In this way, a card-feeding channel of the card-delivering device 42 is formed between the card-feeding projections, the card-distributing cam 4203, the card-feeding ridges, the card-distributing pressure wheel 4221, and the card-distributing wheel 4202, and the card-feeding channel with concave-convex coordination helps to squeeze and rub the overlapping multiple playing cards to separate them, ensure that the multiple playing cards entering the positions of the card-distributing wheel and the card-distributing pressure wheel are separated front and back, and limit the number of playing cards entering at the same time. Further preferably, a plurality of card-feeding projections and a plurality of card-distributing cams are arranged alternately and staggered to obtain a better card-distributing separation effect.

[0098] It is further preferred that the card dividing pressing wheel and the card dividing wheel are staggered front and back and overlapped up and down (that is, the axis of the card dividing pressing wheel and the card dividing wheel are staggered by a horizontal distance and the card dividing pressing wheel is closer to the card storage space of the card storage box than the axis of the card dividing wheel, and the bottom of the card dividing pressing wheel is lower than the highest point of the card dividing wheel).

[0099] The components of the card-splitting wheel, the card-delivering wheel and the card-splitting pressure wheel can each be a roller-type component or be composed of a plurality of wheel-shaped components mounted on the same shaft. One side of the card-delivering wheel 4201 is protruded with arc-shaped saw teeth, so that the playing cards can be pushed upward and forward during the rotation of the card-delivering wheel, so that the playing cards can better cross the card-feeding protrusion, and in addition, this action can also prevent the front and rear playing cards from being stuck against each other when the card-delivering device withdraws the cards. Each card-splitting wheel 4202 includes a support frame with a certain rigidity and a rubber ring sleeved and fixed on the support frame, and the arc-shaped circumference of the rubber ring is a protruding arc-shaped rubber saw tooth for contacting the playing cards, and the arc-shaped rubber saw tooth of the rubber ring is lower than the side wall circumference of the support frame, so that when the arc-shaped rubber saw tooth part of the card-splitting wheel contacts the playing cards, the friction force is large so that the playing cards are easily driven to move, and when the side wall circumference of the supporting frame of the card-splitting wheel contacts the playing cards, the friction force is small so that 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.

[0100] 2. In the present 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 sides 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 side of the playing cards, respectively, so as to improve the recognition accuracy and efficiency of the front and back sides of the playing cards. The two identification elements can be triggered to work by the same detection sensor for detecting the playing cards in place, or they can be triggered to work by two detection sensors for detecting the playing cards in place. 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 on the diagonal fixed position of the playing cards in the conveying channel, so that the controller can identify the front and back sides of the playing cards according to the pattern information, such as determining it as the front side when it is identified as a character pattern. Other structures, principles, action processes, and methods for identifying the front and back sides of playing cards are the same as those in patent documents with publication numbers CN209405643, CN110193184, and their various alternative structures, principles, action processes, and methods.

[0101] In this embodiment, it is also preferred that a thickness measuring component for detecting whether there is overlap in the playing cards passing through the conveying channel is provided on the conveying bottom wall 4204 or the conveying top wall 4218 of the conveying channel, and the thickness measuring component includes a rotating member 4240, a thickness measuring wheel 4241, a thickness measuring sensor 4242 and a thickness measuring conveying wheel 4243. The thickness measuring wheel 4241 and the thickness measuring conveying wheel 4243 correspond to each other up and down and are respectively installed on the conveying bottom wall 4204 and the conveying top wall 4218 of the conveying channel, the shaft of the thickness measuring wheel 4241 is installed on the rotating member 4240, one end of the rotating member 4240 is hinged to the conveying bottom wall 4204 or the conveying top wall 4218 of the conveying channel, the other end of the rotating member 4240 is movable and corresponds to the thickness measuring sensor 4242 installed on the conveying bottom wall 4204 or the conveying top wall 4218, and the elastic member gives the rotating member 4240 and the thickness measuring wheel 4241 a tendency to press toward the thickness measuring conveying wheel 4243. 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 upwards, and the thickness measuring sensor 4242 can determine the thickness of the playing cards passing through 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 is a situation where two or more playing cards overlap, and the conveying mechanism returns the playing cards to the card storage box 41 to re-enter and separate the cards. This can further reduce the occurrence of card separation errors and failures. The thickness measuring assembly can be used in conjunction with the thickness measuring structure or method in the patent documents with publication numbers CN209405643, CN110193184, etc., or it can be used alone. Of course, in this embodiment, only the thickness measuring structure or method in the patent documents with publication numbers CN209405643, CN110193184, etc. and its various alternative structures, principles, action processes, and methods can be used.

[0102] In order to facilitate installation, debugging and replacement of parts, the preferred embodiment is that the above sensor adopts a modular design, such as Fig.16 , Fig.17 As shown, the identification element for identifying the front and back of the playing cards and its control circuit are installed on the first circuit board 4219, the thickness sensor 4242 and its control circuit are installed on the second circuit board 4220, and the first circuit board 4219 and the second circuit board 4220 are respectively fixed to the conveying top wall 4218 of the conveying mechanism by fasteners.

[0103] The housing of the card dealing device includes a conveying bottom wall 4204, a conveying top wall 4218, a second card-discharging channel outer side wall 4214, and a flipping channel inner side wall 4215, etc., some of which are integrally formed, and some are fixedly connected. In a preferred embodiment, the conveying bottom wall 4204 is integrally formed with the card storage box bottom wall at one end close to the card storage box, the surrounding side walls of the card storage box (including the card-input side wall 4105 and the card-discharging side wall 4101) are integrally formed and fixedly connected to the card storage box bottom wall, and the conveying top wall 4218 and the conveying bottom wall 4204 are positioned and matched up and down and fixedly connected by a buckle structure or a fastener. This makes it convenient to install, debug, and replace parts.

[0104] 3. If Fig. 9 , Fig.10 , Fig.11 , Fig.16 , Fig.17 , Fig.18 , Fig.19As 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. The first card-discharging pressure wheel 4207, the card-flipping pressure wheel 4211, and the second card-discharging pressure wheel 4212 are all driven wheels. The first card-discharging pressure wheel 4207 and the card-flipping pressure wheel 4211 are respectively in rolling contact with the card-flipping wheel 4210. The second card-discharging pressure wheel 4212 is in rolling contact with the flop pressure wheel 4211, a first card-discharging channel 4208 is formed between the flop wheel 4210 and the first card-discharging pressure wheel 4207, a flop channel 4224 is formed between the flop wheel 4210 and the flop pressure wheel 4211, a second card-discharging channel 4213 is formed between the flop pressure wheel 4211 and the second card-discharging pressure wheel 4212, and the flop wheel 4210 is installed in the inner part of the flop channel 4224. The card-discharging channel 4224 is arranged on the side of the card-discharging wheel 4210 and is located between the first card-discharging channel 4208 and the second card-discharging channel 4213. The card-discharging channel 4224 extends along the partial arc circumference of the card-discharging wheel 4210 from the side of the card-discharging wheel 4210 close to the first card-discharging channel 4208 to the other side of the card-discharging wheel 4210 away from the first card-discharging channel 4208. A card-discharging component 4209 for opening or closing the card-discharging channel 4224 or the first card-discharging channel 4208 is arranged on the outer side of the card-discharging channel 4224 at one end close to the first card-discharging channel 4208. A card-pushing component 4216 is provided on the end of the card-discharging channel 4224 away from the first card-discharging channel 4208. The second card-discharging channel 4213 is arranged on the outer side of the card-discharging channel 4224 at a position opposite to the card-pushing component 4216. The card-discharging component 4209 is driven by the card-discharging driving mechanism to swing, thereby opening or closing the card-discharging channel 4224 or the first card-discharging channel 4208. 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, 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; when the card flipping component 4209 opens the card flipping channel 4224 and closes the exit of the first card outlet channel 4208, the card input channel, the conveying channel, the first card outlet channel 4208, the card flipping channel 4224 and the second card outlet channel 4213 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; After exiting the card exiting passage 4208, the card is blocked by the card flipping component 4209 and turned to enter the card flipping passage 4224, and is sent to the end of the card flipping passage 4224 by the card flipping wheel 4210 and the card flipping pressure wheel 4211. The front end of the playing card abuts against the card pushing component 4216, and the playing card recovers to a straight state after its rear end passes through the card flipping pressure wheel 4211. Under the thrust of the card pushing component 4216, the rear end of the playing card first enters the second card exiting passage 4213 and is sent to the card receiving position of the card receiving seat 2 by the card flipping pressure wheel 4211 and the second card exiting pressure wheel 4212. In this way, the playing card passing through the card flipping passage is turned back and forth and flipped 180 degrees, thereby realizing the flipping of the front and back sides of the playing card.

[0105] In this embodiment, each of the components of the card-flipping wheel 4210, the first card-discharging pressure wheel 4207, the card-flipping pressure wheel 4211 and the second card-discharging pressure wheel 4212 can be a roller-type part, or can be composed of a plurality of wheel-shaped parts installed on the same shaft. In this embodiment, the card-flipping wheel 4210, the first card-discharging pressure wheel 4207, the card-flipping pressure wheel 4211 and the second card-discharging pressure wheel 4212 all include a plurality of wheels installed on their respective shafts, and the card-flipping component 4209 also includes a plurality of components installed on the same rotating shaft. The card-flipping component 4209 and the card-flipping wheel 4210 are staggered, so that the structure is simple and the installation and matching are convenient. Rubber rings can be installed on the card-flipping wheel 4210, the first card-discharging pressure wheel 4207, the card-flipping pressure wheel 4211 and / or the second card-discharging pressure wheel 4212 to increase the friction with the playing cards.

[0106] like Fig.11 As shown, in this embodiment, the flop channel 4224 includes an inner side wall 4215 of the flop channel. The swing center (flop axis) of the flop component 4209 is located in the middle position thereof, so that two swing ends are formed on both sides of the swing center thereof, and the inner side of the flop component 4209 is in an arc shape corresponding to the outer periphery of the flop wheel 4210, so that the flop component 4209 can not only play a good blocking and turning role, but also the flop component 4209 can play the role of the outer side wall of the flop channel, and there is no need to specially set the outer side wall of the flop channel. In other embodiments, the swing center (flop axis) of the flop component 4209 can also be located at one end thereof, and it is necessary to specially set the outer side wall of the flop channel to ensure that the playing cards can pass smoothly in the flop channel 4224.

[0107] like Fig.11 , Fig.19 As shown, 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), so that 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).

[0108] 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 is provided on the outer side wall 4214 of the second card output channel where the second card output wheel 4212 is installed, close to the flipping wheel 4210, to guide the playing cards between the flipping pressure wheel 4211 and the second card output wheel 4212.

[0109] In order to ensure the conveying pressure and avoid slipping, the first card-discharging pressure wheel 4207 and / or the card-flipping pressure wheel 4211 are preferably given a tendency to press the card-flipping pressure wheel 4210 through their respective enabling mechanisms, and the second card-discharging pressure wheel 4212 is preferably given a tendency to press the card-flipping pressure wheel 4211 through the enabling mechanisms. These enabling mechanisms can be elastic components such as springs, spring sheets, elastic rings or elastic shafts (for example, long strip springs are used as the rotating shafts of the pressure wheels), or can be elastic enabling mechanisms composed of multiple components. Similarly, the aforementioned conveying pressure wheels, etc. can also adopt such elastic enabling mechanisms. In this 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 wheel 4210, an elastic rubber ring is installed on the card-flipping pressure wheel 4211 to press the card-flipping wheel 4210, and the second card-discharging pressure wheel 4212 is installed on the outer side wall 4214 of the second card-discharging channel through an elastic shaft to press the card-flipping pressure wheel 4211. This is convenient to install, simple and reliable in structure.

[0110] 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. 9 , Fig.10 , Fig.16 , Fig.17 As shown, the electromagnet 4229 is used for driving, a crank is fixed at one end of the flip shaft 42091 of the flip component 4209, and the swing end of the crank is connected to the active end of the electromagnet 4229 through a connecting rod, so that when the flip component 4209 needs to move, the electromagnet 4229 pulls the flip component 4209 to swing through the connecting rod and the crank. 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.

[0111] 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.

[0112] 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.

[0113] It should be noted that the first card outlet channel 4208 and the second card outlet channel 4213 can be directly connected to the exit of the card receiving position (that is, the card flipping mechanism has two card outlets). Fig.11As shown; in other embodiments, the first card-discharging channel 4208 and the second card-discharging channel 4213 may not be directly connected to the exit of the card-receiving position, 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, and then the playing cards are delivered to the card-receiving position. For example, a fourth card-discharging wheel and a fourth card-discharging pressure wheel are provided outside the exits of the first card-discharging channel 4208 and the second card-discharging channel 4213, and a card-discharging outlet for delivering the playing cards from the first card-discharging channel 4208 or the second card-discharging channel 4213 to the card-receiving position is formed between the fourth card-discharging wheel and the fourth card-discharging pressure wheel. In this way, the two card-discharging outlets of the original first card-discharging channel and the second card-discharging channel are merged into one card-discharging outlet, so that the card dealing is more stable and reliable, and the card drop position is accurate and does not drift. In order to ensure that the playing cards can be quickly and reliably transported from the first card-discharging channel 4208 to the card-discharging port 4227, a third card-discharging wheel and a third card-discharging pressure wheel corresponding to the third card-discharging wheel are provided between the flip wheel 4210 and the fourth card-discharging wheel, and the third card-discharging wheel and the third card-discharging pressure wheel form an extension of the first card-discharging channel 4208 and ensure the transport power. The above-mentioned transport wheel 4205, flip wheel 4210, third card-discharging wheel and fourth card-discharging wheel are all active wheels, and the above-mentioned flip pressure wheel 4211, first card-discharging pressure wheel 4207, second card-discharging pressure wheel 4212, third card-discharging pressure wheel, fourth card-discharging pressure wheel and transport pressure wheel 4217 are all driven wheels. The outer wall of the flop channel (or the flop component 4209) and the inner wall of the first card-discharging channel are located inside the space surrounded by the outer wall of the first card-discharging channel, the outer wall of the second card-discharging channel 4214 and the inner wall of the flop channel 4215, and the outer wall of the first card-discharging channel and the flop pressure wheel 4211 are respectively close to the two ends of the outer wall of the flop channel (or the flop component 4209); further preferably, the inner wall of the first card-discharging channel and the outer wall of the flop channel are fixedly connected as one; it is also preferred that a second card-discharging channel inner wall is provided, the outer wall of the flop channel (or the flop component 4209), the inner wall of the first card-discharging channel and the inner wall of the second card-discharging channel are fixedly connected as one and are distributed on three sides, the flop pressure wheel 4211 is provided at the junction of the inner wall of the flop channel 4215 (or the flop component 4209) and the inner wall of the second card-discharging channel, and the third card-discharging wheel or the third card-discharging pressure wheel is provided on the inner wall of the first card-discharging channel opposite to the flop pressure wheel 4211.

[0114] About the card receiving device.

[0115] The poker machine can be placed on a desktop 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. 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 or drawers can also be opened on the top panel 3 or the side frame of the card table for players to take the poker cards. Such a card receiving device only needs to realize the function of receiving the poker cards, and the structure is relatively simple. 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 desktop, so that it will not affect the players' playing cards, and it is very convenient to manufacture, install and maintain. In this use scenario, in addition to realizing the function of receiving the poker cards, the card receiving device also needs to be equipped with a card lifting function or a card lifting device 21 to lift the poker cards in each card receiving device that has been distributed to the desktop for players to take the poker cards.

[0116] In the structures disclosed in patent documents such as CN209405643 and CN110193184, a lifting whole movement (including a card receiving device) is used to lift the playing cards in each card receiving device to the table. For the poker machine with a card sorting device in this embodiment, the whole movement is large in size (more than 60 cm), the lifting mechanism is complex, the motor load is large, and the manufacturing cost is high, which is not suitable for use. Therefore, the following card receiving device is preferred in this embodiment:

[0117] 1. Card receiving device with lifting function.

[0118] like Figure 2 , Figure 3 , Figure 4The card receiving device 20 shown includes a plurality of card receiving boxes 210 and a plurality of card pushing plates 202 arranged around a card dealer 40 and a card handling device 6, and the card receiving boxes 210 and the card pushing plates 202 are arranged in a one-to-one correspondence; the plurality of card receiving boxes 210 are fixed on a rotating ring 211, and the rotating ring 211 is rotatably mounted on the base 1 by a plurality of supporting rollers, and the rotating ring 211 is driven to rotate by a rotating motor 203, and a card pushing groove for slidingly cooperating with the card pushing plate 202 is provided at the bottom of each card receiving box 210; the card pushing plate 202 is driven by a card pushing driving mechanism to reciprocate from the inside of the card receiving box 210 to the outside of the card receiving box 210.

The card pusher chute 21 extends from the inside to the outside of the card receiving box 210, and the card pusher chute 21 is preferably arranged radially along the circumference of the rotating ring 211. An internal gear is provided on the inner side of the rotating ring 211, and the rotating motor 203 is driven by meshing the gear with the internal gear on the rotating ring 211.

[0119] The card pushing driving mechanism is arranged on the base 1, and includes 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 base 1 through a plurality of positioning rollers B 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 a driving part is connected to a The middle part of each card-pushing swing arm 207 is movably connected through a chute A, one end of the card-pushing swing arm 207 is movably connected (hinged) with the base 1, and the other end of the card-pushing swing arm 207 is movably connected (hinged) with the bottom of the card-pushing plate 202, 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 outside of the card receiving box 210 to the inside of the card receiving box 210 or to do a reset action from the inside of the card receiving box 210 to the outside of the card receiving box 210. 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 matching structure. The card pushing driving component 206 is located on the inner side of the rotating ring 211. In order to facilitate the hinge connection with the card pushing swing arm 207, a plurality of card pushing fixing frames 212 corresponding to the card pushing swing arm 207 are fixed on the base 1. One end of the card pushing swing arm 207 is hinged to the card pushing fixing frame 212. The hinged end of the card pushing fixing frame 212 is located above the rotating ring 211 and on the inner side of the connection between the card receiving box 210 and the rotating ring 211.

[0120] In this embodiment, the card receiving box 210 is an internal and external through structure, and a plurality of card receiving boxes 210 are surrounded by a retaining ring 214 and a card raising ring 213 on the outer side, and a plurality of card receiving positions corresponding to the card receiving boxes 210 are arranged on the card raising ring 213, and the card raising ring 213 is driven to rise and fall by the lifting drive mechanism, so as to raise a pile of playing cards of each party from the card loading port 302 to the table. In order to save space and optimize the structure, it is preferred to place a pile of playing cards in a leaning manner on the card holding position of the card raising ring 213. When dealing cards, the retaining ring 214 blocks the outer side of the card receiving box 210 to prevent the playing cards from falling out of the card receiving box 210, and when pushing cards, the retaining ring 214 descends, and the card pushing plate 202 pushes the playing cards in the card receiving box 210 to the card holding position of the card raising ring 213. Preferably, the retaining ring 214 is integrally formed or fixedly arranged at the lower part of the card raising ring 213.

[0121] The lifting drive mechanism includes a lifting drive component 5, a lifting motor 501 and multiple lifting swing arms 503. The multiple lifting swing arms 503 are evenly distributed below the card lifting ring 213. One end of the lifting swing arm 503 is hinged to the base 1, and the other end of the lifting swing arm 503 is against the bottom of the card lifting ring 213. The lifting motor 501 drives the multiple lifting swing arms 503 to swing synchronously through the lifting drive component 5, thereby pushing the card lifting ring 213 to rise and fall. In this embodiment, the lifting drive member 5 is in the shape of a circular ring, and a plurality of lifting protrusions 502 corresponding to the plurality of lifting swing arms 503 are arranged on the top of the ring, and the lifting protrusions 502 are against the middle support rollers of the lifting swing arms 503.
