Description

Technical Field

[0001] The present invention relates to playing card equipment, and more particularly to a shuffler structure for achieving more uniform and fair shuffling. Background Art

[0002] Generally speaking, before playing a poker game, the entire deck of cards needs to be shuffled so that the entire deck of cards is arranged in random numbers, so that the patterns and point combinations in the hands of the players in each game can be as different as possible, so as to avoid the situation where certain players often get certain cards, thereby affecting the fairness and fun of the game. However, if the shuffling action is done manually, it is easy to cause uneven shuffling. Moreover, during the shuffling process, the shuffler can often use subtle and skilled hand movements to draw, mark, bend, and other tricks or sleight of hand to control the players' cards, resulting in the existence of human manipulation factors in the game, which makes people suspect cheating and affects the fairness of the game. In order to improve the above-mentioned problem, some businesses have developed automatic shuffling machines to replace manual shuffling with machines to avoid people from touching the playing cards. The known playing card shuffling machines simulate the manual shuffling action and are provided with two playing card boxes on the left and right. The playing cards are evenly stacked in the two card boxes respectively. The playing cards in the card boxes are pushed out in sequence to the center of the two card boxes and stacked in an interlaced manner by the rotation of the rollers to complete the shuffling action. Although the two stacks of playing cards are interlaced with each other, the order of the original single stack of playing cards is not changed. In other words, the order of the cards appearing is only reversed, but the patterns and points are not disrupted. Therefore, players may suspect that the shuffling is still uneven. In view of this, in order to increase the uniformity and fairness of the shuffling, the inventor of the present case has carefully considered and accumulated many years of development and manufacturing experience in related industries, and finally came up with the present invention.

[0016] The composition and function of the present invention are described in detail as follows: Figures 1 to 9 As shown, the present invention is electrically connected to a control device (not shown in the figure), and the control device can be a circuit board or a computer, but is not limited thereto. When the present invention is used, the shuffler 10 is started, the lifting platform 23 first descends to the bottom of the shuffle tank 12, and the card box 60 containing multiple decks of playing cards 1 is placed in the box inlet 17, so that the lifting platform 23 is located at the bottom of the card box 60 (such as Figure 3 As shown in the figure, the shuffling tank 12 has the cutout 19, and the card box 60 has the top opening 62, the bottom cutout 63 and the rear cutout 64, so that the card moving slide 22 can drive the lifting platform 23 to move arbitrarily without obstruction; at this time, the card dispensing slide 32 of the card dispensing mechanism 30 is driven to randomly move one of the grid layers 34 of the card dispensing box 33 to correspond to the card dispensing opening 51, and then the card moving slide 22 of the card moving mechanism 20 is driven to drive the lifting platform 23 to rise and touch the bottom of the playing cards 1, and the lifting platform 23 continues to rise (as shown in the figure). Figure 4 As shown), the lifting platform 23 with the playing cards 1 is raised to the position of the card dispensing opening 51 of the card dispensing module 50 through the bottom opening 63 and the top opening 62 (as shown in FIG. Figure 5As shown in the figure, the card discharging module 50 comprises an upper roller 52 driven to rotate by an external power and a lower roller 53 clamped with the upper roller 52. The shuffling slot 12 is provided with a connecting port 121 corresponding to the card discharging port 51. The upper roller 52 and the lower roller 53 are pivotally assembled on a shell cover 54. The shell cover 54 covers the connecting port 121, and the shell cover 54 is provided with the card discharging port 51. The card guide wheel assembly 24 rotates to transport a playing card 1 through the connecting port 121 into the gap between the upper roller 52 and the lower roller 53, so that the playing card 1 The card dispensing opening 51 sends the playing card 1 to the corresponding grid layer 34; then the card dispensing slide 32 of the card dispensing mechanism 30 is driven to randomly position one of the grid layers 34 of the card dispensing box 33 corresponding to the card dispensing opening 51, and the card guide wheel set 24 conveys another playing card 1 from the card dispensing opening 51 to the corresponding grid layer 34; the above-mentioned random number position drives one of the grid layers 34 of the card dispensing box 33 to correspond to the card dispensing opening 51, and the playing card 1 is randomly distributed one by one to the grid layers 34 of the card dispensing box 33 (such as Figure 6 As shown), until the photoelectric sensor 25 detects that there is no playing card 1 on the lifting platform 23 and sends a signal to the control device, causing the card guide wheel set 24 to stop moving.

[0017] It is worth noting that during the card dispensing process, if the photoelectric sensor 25 detects that there are playing cards 1 on the lifting platform 23, when the lifting platform 23 rises to a set height, the shuffler 10 can determine that the number of playing cards 1 remaining on the lifting platform 23 is small. At this time, the card pressing lever wheel 18 is pivoted through the through slot 16 to press against the playing cards 1 on the lifting platform 23 (such as Figure 7 As shown), the weight of the playing cards 1 is increased so that the card guide wheel set 24 can continue to spit out the cards smoothly.

[0018] Regarding the setting of the position of the grid layer 34 driven by the random number position, an example is given as follows: assuming that there are sixteen grid layers 34 in the card distribution box 33, which are numbered 1 to 16 from top to bottom, during the shuffling action of the shuffler 10, the random number setting position sequence of spitting the playing cards 1 into the grid layer 34 can be numbered 1→2→3→16→15→14→4→5→6→13→12→11→7→8→10→9 or numbered 8→11→1→6→15→4→9→2→7→13→3→14→5→12→16→10...etc., there are at least 20 random number position sequences, and the last one is a natural random number without sorting.

[0019] When the playing cards 1 in the card box 60 are randomly distributed in piles on the grid layer 34 of the card distribution box 33, at this time, the lifting platform 23 moves down to the height position of the card entry port 15, drives the card distribution slide 32 of the card distribution mechanism 30 to drive the card distribution box 33, so that one of the grid layers 34 of the card distribution box 33 corresponds to the card entry port 15, and then drives the card pushing slide 42 of the card pushing mechanism 40 to drive the pushing block 45, so that the pushing block 45 enters the grid layer 34, and pushes the pile of playing cards 1 back to the lifting platform 23 through the card entry port 15 (such as Figure 8 As shown); the transmission belt 43 of the card pushing mechanism 40 is driven by a motor 46 having a driving wheel 47 and a driven wheel 48 arranged on the bottom plate 11, and the transmission belt 43 is wound around the driving wheel 47 and the driven wheel 48, so that the motor 46 rotates forward and reversely, thereby linking the card pushing slide 42 to slide horizontally on the card pushing slide rail 41, and making the stand 44 and the push block 45 synchronously move to push the playing cards 1 in the grid layer 34; repeating the above-mentioned actions, the playing cards 1 are pushed back to the lifting platform 23 in piles, and the lifting platform 23 will gradually move down according to the current height so that the playing cards 1 can be pushed back normally until there are no cards in the card distribution box 33.

[0020] It is worth mentioning that when the push block 45 pushes the playing cards 1 in the card distribution box 33 back to the lifting platform 23, the card distribution box 33 is displaced so that the grid layers 34 correspond to the push blocks 45 one by one. The corresponding manner can be sequentially corresponding from top to bottom, sequentially corresponding from bottom to top, or corresponding by random number positions. The random number position correspondence can achieve a double destruction of the shuffling action of the arrangement order (such as Fig. 9 As shown), the disorder of the playing cards can be improved, achieving a more uniform and fair shuffling effect.

[0021] When all the playing cards 1 are returned to the card box 60, the shuffler 10 of the present invention can be used with a robot arm or other opening mechanism to open the cards; the lifting platform 23 can lift the playing cards 1 to the top of the shuffle slot 12 for the robot arm to suck the cards or the opening device to extract and use, and then put the used playing cards 1 back into the recycling slot 13, and finally merge the unused playing cards 1 in the shuffle slot 12 with the playing cards 1 in the recycling slot 13 to perform the shuffle action again, and the recycling slot 13 transports the playing cards 1 to the shuffle slot 12. This part of the structure is not the application target of this case and will not be described in detail. Of course, if the present invention is used as an independently operated shuffler 10, the shuffled playing cards 1 can also be taken out of the card box 60 to complete the shuffle action for use in other opening methods.

[0022] The above is only a preferred embodiment of the present invention. Therefore, any equivalent structural changes made by applying the present invention should be included in the patent scope of the present invention.
