Description

Technical Field

[0001] The invention relates to the field of poker machines, and in particular to a poker machine and a card upgrading device and a card upgrading 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, after the card receiving device receives the playing cards sent by the card dealer, the card lifting structure lifts the playing cards in each receiving device onto the table for the player to take the playing cards. This makes the card receiving device complex in structure and large in size, and it is not suitable for some poker machines with simplified functions, such as a poker machine in which the player reaches into the card taking port to take the playing cards.

[0012] The patent document with the publication number CN113304463A discloses a receiving device that cooperates with card receiving and card raising, including a plurality of receiving boxes arranged around a card dealing device and a card handling device, the plurality of receiving boxes being fixed on a rotating ring, the rotating ring being mounted on a base in a rotatable manner by a plurality of supporting rollers, the rotating ring being driven to rotate by a rotating motor, a plurality of card raising devices being arranged on the base, the card raising devices being arranged one by one with the receiving boxes, the card raising devices comprising a card bearing arm for supporting playing cards and a card raising driving mechanism for driving the card bearing arm to rise and fall, the bottom of the receiving box being provided with an opening corresponding to the card bearing arm for the card bearing arm to pass through and rise and fall. When the card dealing device deals cards, the plurality of receiving boxes rotate to randomly receive cards, and the card raising device and its card bearing arm do not affect the dealing of cards; when the card raising device raises cards, the receiving box stays above the card bearing arm of the card raising device, the card raising driving mechanism drives the card bearing arm to rise upward, and the card bearing arm supports the playing cards in the receiving box and raises them onto the table of the poker machine. In this structure, the card receiving box has four side walls (including an outer wall, an inner wall and left and right side walls). Because multiple card receiving boxes are fixed on a rotating ring and rotate around a specific circle, and the card outlet of the card dealer is a right-angled side, the matching gap between the card receiving box and the card dealer is large, and the card storage space in the card receiving box is not large enough. Therefore, the playing cards need to fly a long distance from the card outlet of the card dealer to the card receiving box. The card receiving box cannot receive the playing cards well, and there will still be problems such as the playing cards being placed on the inner wall of the card receiving box or even the playing cards falling out of the card receiving box during the rotating card receiving process.

[0013] Patent document with publication number CN103055500B discloses a card-lifting device for the above-mentioned poker machine, including a card-lifting seat, a card-lifting port on the card-lifting seat, two door-opening plates in the card-lifting port, the door-opening plates are driven by their driving mechanism to rotate and open in the card-lifting port, and a card-supporting plate is provided below the card-lifting port, and the card-supporting plate is driven by its driving mechanism to rise and fall. In this structure, an independent motor is required to control the door-opening plate to open or close, so each card-lifting device requires two motors, a card-lifting motor and a door-opening motor, which increases the manufacturing cost. Summary of the invention

In this way, the chaotic playing cards put in from the card placement port are rotated and moved into the arc-shaped card sorting channel by the central turntable, and the playing cards whose length direction is basically consistent with the conveying direction of the conveying roller in the arc-shaped card sorting channel are sent out from the exit of the card sorting channel by the conveying roller, and the playing cards whose length direction is inconsistent with the conveying direction of the conveying roller in the arc-shaped card sorting channel are respectively rotated by the central turntable and the conveying roller on the inner and outer sides of the playing cards until their 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 sorting the chaotic and disordered playing cards into width direction and sending them forward to achieve card sorting. The preferred mode is that the rotation direction of the central turntable is opposite to the direction in which the conveying roller conveys the playing cards to promote the rotation of playing cards with inconsistent directions, thereby sorting the playing cards into a certain direction and improving the efficiency of card sorting.

[0043] The above-mentioned card dealer is a prior art, and the specific structures disclosed in the series of patent documents with publication numbers CN113018838A, CN112587909A, CN112870684A, CN113304460A, CN111318004A, CN110801621A, etc. can be used. Generally speaking, the card dealer 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. That is, the card dealer is fixed on the base and located below the card handling seat, and the card dealer includes a card storage box and a card dealing device. The upper opening of the card storage box is located below the exit of the card handling channel, and one side of the bottom of the card storage box is connected to the card feeding channel of the card dealing device. The card dealing device includes a card dividing mechanism, a conveying mechanism and a card flipping mechanism, and the card flipping mechanism is located below the outer side of the central turntable. In the present embodiment, the card storage box, the card dividing mechanism, the conveying mechanism and the card flipping mechanism convey the playing cards along the width direction of the playing cards, and their structures, principles, operation processes and methods can adopt the structures, principles, operation processes and methods disclosed in patent documents with publication numbers CN209405643, CN110193184, CN112587909A, CN112870684A, CN113304460A, CN111318004A, CN110801621A and the like, as well as various alternative structures, principles, operation processes and methods disclosed in patent documents with publication numbers CN209405643, CN110193184, CN112587909A, CN112870684A, CN113304460A, CN111318004A, CN110801621A and the like, and the same contents will not be repeated here.

[0044] In this embodiment, the card receiving device and the card raising device cooperate with each other to achieve the card raising action of playing cards. Specifically:

[0045] like Figure 1 The card receiving device of a poker machine shown in the figure comprises a plurality of card receiving boxes 5 arranged around a card dealer, wherein the plurality of card receiving boxes 5 are fixed on a rotating ring 6 and are located outside the rotating ring 6, and the rotating ring 6 is rotatably mounted on a base 1, and the rotating ring 6 is driven by a rotating motor to rotate around the card dealer, such as Figure 3 As shown, each receiving box 5 includes a receiving box body 501, the receiving box body 501 has an outer wall 5011, a right wall 5012, a left wall 5013 and a bottom wall 5015, and the inner side of the receiving box body 501 is an open end; an inner retaining ring 2 is also fixed on the base 1, and the inner retaining ring 2 is located above the rotating ring 6 and the inner side of the plurality of receiving boxes 5, as shown in FIG. Figure 2As shown, the lower outer wall of the inner card baffle ring 2 is in a circular shape, and the upper outer wall of the inner card baffle ring 2 includes an arcuate card baffle wall 202 and a linear card baffle wall 203, the linear card baffle wall 203 cooperates with the card outlet of the card dealer, and the inner card baffle ring 2 forms a card dealing step 2031 between the linear card baffle wall 203 and the lower outer wall; when a card receiving box 5 rotates to the outside of the card outlet of the card dealer, the card dealing step 2031 cooperates with the bottom wall 5015 of the card receiving box 5, the linear card baffle wall 203 constitutes the inner wall of the card storage space of the card receiving box 5, and the arcuate card baffle wall 202 constitutes the inner wall of the card storage space of other card receiving boxes 5.

[0046] In this way, the inner walls of multiple card receiving boxes are realized by a fixed inner card baffle ring. When a card receiving box is rotated to the outer side of the card outlet of the card dealer, the card dealing step on the inner card baffle ring is matched and connected with the bottom wall of the card receiving box, and a straight card baffle wall is used to form the inner wall of the card storage space of the card receiving box, thereby achieving the technical effect of reducing the matching gap between the card receiving box and the card dealer and increasing the card storage space in the card receiving box when receiving cards, and completely avoiding the failure of playing cards being placed on the inner wall of the card receiving box or playing cards falling out of the card receiving box during the rotating card receiving process.
