Description

Technical Field

[0001] The present invention relates to a card shuffler, in particular to a card shuffler with a rising card-moving device, which can avoid damage to mis-moved playing cards, and a magnetic attraction member for attracting the card-pressing arm, so as to increase friction and ensure smooth transmission without idling. Background Art

[0002] Known playing card shuffling machines, such as Figures 1 to 4 As shown, the shuffler 10 is provided with a central containing groove 11, a left containing groove 12, and a right containing groove 13, and a card-digging space 14 is provided on the central containing groove 11, the left containing groove 12 and the right containing groove 13, respectively. A card-guiding wheel group 15 is provided on both sides of the top of the central containing groove 11, and a card-transmitting wheel group 16 is provided on the bottom of the left containing groove 12 and the right containing groove 13, respectively. The central containing groove 11 is provided with a liftable central lifting platform 17, and a liftable lifting platform 18 is provided in each of the left containing groove 12 and the right containing groove 13. A translation plate 19 is also provided, which is displaceably arranged at a predetermined height on the top of the central containing groove 11, the left containing groove 12 and the right containing groove 13, and the translation plate 19 includes a card-digging piece 20 extending downwardly, and a driving mechanism 21 is also provided, which is connected to the translation plate 19, and can drive the translation plate 19 to move back and forth in the left and right directions of the card-digging space 14, so that the card-digging piece 20 moves back and forth in the left and right directions of the card-digging space 14, so that the card-digging piece 20 moves back and forth in the left and right directions of the card-digging space 14. The card shifting space 14 can shift the playing card 1 located in the central receiving slot 11 to the left receiving slot 12 or the right receiving slot 13; the outer sides of the left receiving slot 12 and the right receiving slot 13 are respectively pivoted with a card pressing arm 22 with a return spring 221, and the other end of the card pressing arm 22 is provided with a card pressing wheel 222. When the lifting platform 18 in the left receiving slot 12 and the right receiving slot 13 carries the playing card 1 and descends, each of the card pressing arms 22 can pivotally press the playing card 1, and the elastic force of the return spring 221 can make the card pressing wheel 222 have a downward pressure against the playing card 1, so that each of the card transfer wheel groups 16 can rotate and smoothly guide the playing card 1 to the central lifting platform 17 by friction to avoid idling, thereby simulating manual operation and achieving the automatic card cutting and shuffling function; however, the above-mentioned shuffling machine 10, although the playing card 1 can be automatically cut and shuffled, still has the following disadvantages:

[0003] When the card shifting piece 20 shifts the playing card 1 from the central receiving slot 11 to the left receiving slot 12 or the right receiving slot 13, the used playing card 1 may be tilted or arched, and the playing card 1 that should not be shifted may be mistakenly shifted by the card shifting piece 20 due to the tilted or arched high point, so that one end of the mistakenly shifted playing card 1 abuts against the edge of the card guide wheel set 15, and the other end is still forcibly shifted by the card shifting piece 20, causing the playing card 1 to be bent, deformed, and damaged (such as Figure 2 shown).

[0004] Alternatively, when the stacked playing cards 1 are moved by the card shifting piece 20, the moved playing cards 1 are attracted to the card guide wheel set 15 of the left receiving groove 12 or the right receiving groove 13 due to the adsorption relationship between the two planes of the playing cards 1, and the playing cards 1 below are driven to the card guide wheel set 15 of the left receiving groove 12 or the right receiving groove 13, and when the adsorption force weakens halfway, the playing cards 1 fall down, so that they are stuck between the card shifting piece 20 and the card guide wheel set 15 (such as Figure 3 As shown), this will cause the shuffler 10 to malfunction and also affect the fairness of the game.

[0005] When the shuffling machine 10 performs a shuffling action, that is, the playing cards 1 are staggeredly transferred from the left and right receiving slots 12 and 13 to the central receiving slot 11 by the card transfer wheel set 16, the card pressing arm 22 uses the elastic force of the return spring 221 to press the card pressing wheel 222 against the playing cards 1, thereby increasing the friction between the playing cards 1 and the card transfer wheel set 16, so that the rotatable card transfer wheel set 16 can actually transfer the playing cards 1 into the central receiving slot 11, but the playing cards 1 accommodated in the left and right receiving slots 12 and 13 gradually decrease due to being transferred out, and the total thickness of the remaining small amount of playing cards 1 will of course become thinner, so that the card pressing wheel 222 pressed down by the return spring 221 can no longer have the same downward force to press the playing cards 1, that is, the elastic force of the return spring 221 is weakened, so that the friction between the playing cards 1 and the card transfer wheel set 16 is reduced, and even the return spring 221 has lost its elastic force to press the playing cards 1 (such as Figure 4 As shown in FIG. 1 , the card transfer wheel set 16 is caused to idle and fail to actually drive the playing card 1 .

[0006] When the above situation occurs, the obstacle must be removed manually, which makes the shuffler 10 have a high failure rate, affects fairness, reduces the players' interest in the game, and causes unnecessary waste of playing cards 1. Therefore, there is a need for improvement. Summary of the invention

[0101] Furthermore, a card pressing arm 60 having a return spring 61 is pivotally assembled on the outer side of the left receiving groove 32 and the right receiving groove 33, and a card pressing wheel set 62 is respectively arranged at the other end of each card pressing arm 60, and each card pressing wheel set 62 includes at least one magnetic attraction wheel 63, and each card transfer wheel set 36 is provided with at least one magnetic attraction member 64 corresponding to the magnetic attraction wheel 63; a camera 65 is respectively arranged under the card transfer wheel set 36 of the left receiving groove 32 and the right receiving groove 33, and a counting sensor is respectively arranged above the card transfer wheel set 36 between the central receiving groove 31 and the left receiving groove 32 and between the central receiving groove 31 and the right receiving groove 33. The device 66, the camera 65 can identify the pattern and points of the playing cards 1, and the counting sensor 66 can count the number of playing cards 1. Thereby, when there are fewer playing cards 1 left in the left receiving slot 32 or the right receiving slot 33, the magnetic element 64 can attract the magnetic wheel 63 to increase the force of the card pressing wheel set 62 pressing against the playing cards 1, so as to achieve the practical effect of increasing friction to ensure smooth transmission without idling; and when the card transfer wheel set 36 transfers the playing cards 1 to the central receiving slot 31, the pattern points and number of the entire deck of playing cards 1 are recorded, so as to achieve the effect of avoiding omissions and cheating that affect fairness.

[0102] The composition and function of the present invention are described in detail as follows: Figures 5 to 19As 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 to this; the left sensor 41, the fixed point sensor 42 and the right sensor 43 of the driving device 40 can be proximity switches, and the left sensing end 46, the right sensing end 47, the left sensing member 48 and the right sensing member 49 can be made of metal material, and the left sensor 41, the fixed point sensor 42 and the right sensor 43 are used to sense and send signals to the control device, but is not limited to this.

[0103] The upper magnetic member 514 and the lower magnetic member 524 of the card shifting device 50 can be magnets, and the two are arranged in a mutually exclusive manner with the same polarity, that is, the polarity of the arrangement can be NS, SN or SN, NS from top to bottom, so that the fixing seat 51 can be pushed downward away from the shifting block 52. The magnetic wheel 63 of the card pressing wheel set 62 is a magnetic material, such as metals such as iron, nickel, and cobalt, and the magnetic member 64 of the card transfer wheel set 36 can be a magnet, and the magnetic wheel 63 can be attracted within the magnetic field of the magnetic member 64.

[0104] The fixing seat 51 of the card-shifting device 50 is fixed to the translation plate 39, and the shifting block 52 can move up and down on the guide wheel 516 of the fixing seat 51 by means of the vertical track groove 522. In this way, when the two sides of the shifting block 52 are subjected to force when shifting cards, it can be ensured that the two sides of the shifting block 52 are in a vertical plane to shift cards, and also make it move with the translation plate 39 without shaking; and the long groove 521 of the shifting block 52 is used for upper and lower limit when sliding along the screw 53, and also provides a protection against left and right shaking. Efficacy: The magnetic member 64 of the card transfer wheel set 36 is set to be lower than the top edge of the card transfer wheel set 36, and when the number of playing cards 1 is small, the magnetic member 64 can produce mutual magnetic attraction with the magnetic wheel 63. At this time, the reset spring 61 is in a state of weak elastic force or even no elastic force. The magnetic force of the magnetic member 64 provides the card pressing arm 60 with auxiliary force to press the playing cards 1, so as to solve the problem that the reset spring 61 cannot press the playing cards 1 reliably when the number of playing cards 1 is small. When shuffling is to be performed, all the playing cards 1 are placed in the central lifting platform 37 of the central receiving slot 31, and the central lifting platform 37 gradually rises to send the playing cards 1 into the card shifting space 34. The driving mechanism 40 drives the translation plate 39 to slide left and right. For example, the playing cards 1 are firstly shifted into the left receiving slot 32, and the translation plate 39 is driven to shift the playing cards 1 located in the card shifting space 34 from right to left. The shifting block 52 of the card shifting device 50 maintains the mutual repulsive force of the upper and lower magnetic members 514 and 524 to shift the right side of the playing cards 1 (such as Fig.11As shown in FIG. 1 , the side surface and the beveled edge 523 of the shifting block 52 simultaneously push the playing card 1 toward the left receiving groove 32. During the shifting process, if a playing card 1 that is warped or arched due to long-term use is mistakenly shifted by the beveled edge 523 of the shifting block 52, the mis-shifted playing card 1 is a high point at a certain part of the edge of one end, and the high point is usually mis-shifted by the beveled edge 523 of the shifting block 52, and the other end of the playing card 1 may be mis-shifted at a wrong angle (downward angle) and be moved by the card guide wheel. The shift block 52 is blocked by the upper magnetic member 514 and the lower magnetic member 524, but the shift block 52 does not stop shifting cards at this time. When the shift block 52 continues to move, the playing card 1 supported between the bevel edge 523 of the shift block 52 and the card guide wheel group 35 generates a greater blocking force on the shift block 52. The bevel edge 523 of the shift block 52 guides the edge of the playing card 1 along the inclined surface of the bevel edge 523 to generate a force to slide downward. At the same time, the shift block 52 generates a reaction force to resist the repulsive magnetic forces of the upper magnetic member 514 and the lower magnetic member 524 and rise (such as Fig.12 As shown in FIG. 3 ), the playing card 1 is separated from the edge of the shift block 52 by the bevel edge 523 and falls back into the central receiving groove 31, so as to avoid bending the playing card 1 and causing damage. After the playing card 1 is accidentally shifted, the bottom of the shift block 52 is free of obstacles. At this time, the repulsive magnetic forces of the upper magnetic member 514 and the lower magnetic member 524 cause the shift block 52 to drop to its original height. Then, the translation plate 39 continues to shift the card to the left, so that the playing card 1 passes through the card guide wheel set 35. When the right sensing end 47 of the translation plate 39 is shifted to the top of the fixed point sensor 42 (as shown in FIG. 3 ), the playing card 1 is moved to the left, and ... Fig.14 As shown in FIG. 1 ), the fixed point sensor 42 can sense and send a signal to the control device, so that the driving mechanism 40 stops driving the translation plate 39, which is the first displacement stroke of the left shifting card. At this time, the optical fiber sensor 54 of the card shifting device 50 corresponds to the position of the card guide wheel group 35 (as shown in FIG. Fig.13 As shown in the figure, the control device simultaneously makes each optical fiber sensor 54 sense and detect whether there is a playing card 1 between the card guide wheel set 35 and the card shifting device 50. This situation is usually caused by improper adsorption of the playing cards 1. The optical fiber sensor 54 of the present invention is a short-range sensing sensor, which only senses the playing cards 1 between the card guide wheel set 35 and the card shifting device 50. If the presence of a playing card 1 is detected, the control device will make the card guide wheel set 35 rotate in the opposite direction to the central receiving groove 31 for a set time, so that the playing card 1 that is not correctly shifted returns to the central receiving groove 31; then, the shifting block 52 continues to shift the playing card 1. When the left sensing member 48 of the translation plate 39 moves close to the upper side of the left sensor 41 (as shown in the figure), the control device 54 senses and detects whether there is a playing card 1 between the card guide wheel set 35 and the card shifting device 50. Fig.15As shown in the figure), the left sensor 41 can sense and send a signal to the control device, so that the driving mechanism 40 stops driving the translation plate 39. This is the second displacement stroke of the left shifting. At this time, the playing card 1 has been correctly shifted to the lowering platform 38 of the left receiving slot 32, and the left shifting is completed. Of course, if the optical fiber sensor 54 of the card shifting device 50 does not detect any incorrectly shifted playing card 1 between the first and second displacement strokes, there is no need to reverse the rotation of the card guide wheel set 35. On the contrary, the central lifting platform 37 rises again to send the playing card 1 into the card shifting space 34, and the translation plate 39 is driven to shift the playing card 1 located in the card shifting space 34 from left to right. When the left sensing end 46 of the translation plate 39 is displaced to above the fixed point sensor 42 (as shown in the figure), the playing card 1 is correctly shifted to the lowering platform 38 of the left receiving slot 32, and the left shifting is completed. Of course, if the optical fiber sensor 54 of the card shifting device 50 does not detect any incorrectly shifted playing card 1 between the first and second displacement strokes, there is no need to reverse the rotation of the card guide wheel set 35. On the contrary, the central lifting platform 37 rises again to send the playing card 1 into the card shifting space 34, and the translation plate 39 is driven to shift the playing card 1 located in the card shifting space 34 from left to right. Fig.16 ), and the driving mechanism 40 stops driving the translation plate 39, which is the first displacement stroke of rightward shifting. At this time, the optical fiber sensor 54 of the card shifting device 50 senses and detects whether there is a playing card 1 between the card guide wheel set 35 and the card shifting device 50. Then, the shifting block 52 continues to shift the playing card 1. When the right sensing member 49 of the translation plate 39 moves close to the top of the right sensor 43 (as shown in FIG. 1 ), the driving mechanism 40 stops driving the translation plate 39. This is the first displacement stroke of rightward shifting. At this time, the optical fiber sensor 54 of the card shifting device 50 senses and detects whether there is a playing card 1 between the card guide wheel set 35 and the card shifting device 50. Then, the shifting block 52 continues to shift the playing card 1. When the right sensing member 49 of the translation plate 39 moves close to the top of Fig.17 As shown), the driving mechanism 40 stops driving the translation plate 39, which is the second displacement stroke for shifting the cards to the right, and the shifting of the cards to the right is completed; this cycle is repeated until there are no playing cards 1 in the central lifting platform 37, that is, the card shifting operation is completed.

[0105] At this time, the playing cards 1 have been distributed and moved to the lifting platforms 38 of the left and right receiving slots 32 and 33. The lifting platforms 38 are lowered so that the bottoms of the playing cards 1 located in the left and right receiving slots 32 and 33 respectively contact the card transfer wheel set 36. Then, the card pressing arms 60 are able to pivot from outside to inside due to the lowering of the lifting platforms 38, so that the card pressing wheel sets 62 are pressed against the playing cards 1 respectively, so that the playing cards 1 have appropriate pressure against the card transfer wheel set 36, that is, the playing cards 1 are pressed. Appropriate friction is generated between the playing cards 1 and the card transfer wheel set 36, so that each of the card transfer wheel sets 36 rotates toward the center of the shuffler 30, and the playing cards 1 at the bottom of both sides are transferred one by one to the central lifting platform 37 of the central receiving slot 31 by friction to perform a shuffling operation of collecting random numbers; before each playing card 1 is transferred to the central receiving slot 31, the camera 65 under each of the card transfer wheel sets 36 can identify the pattern and points of the playing card 1 (such as Fig.18 As shown in the figure, after the playing cards 1 are shuffled, their patterns and points meet the requirements, and of course, cheating by replacing the cards can be avoided; furthermore, when each playing card 1 passes through the central slot 31, the counting sensor 66 above each card transfer wheel group 36 can count the number of playing cards 1 (such as Fig.19As shown), it ensures that the entire deck of playing cards 1 used in the game is provided without omission; of course, if a playing card 1 is missing, the missing playing card 1 can be easily checked by using the pattern and points recognized by the camera 65 and the number of playing cards 1 counted by the counting sensor 66, thereby achieving the practical effect of self-detection and avoiding omissions and cheating.

[0106] When there are fewer playing cards 1 remaining in the left and right receiving slots 32 and 33, the elastic pressure generated by the return spring 61 on the card pressing arm 60 is not as strong as the elastic force when there are more playing cards 1 at the beginning. Even after the shuffler 30 has been used for a long time, the return spring 61 is elastically fatigued, that is, although there are still playing cards 1 in the left and right receiving slots 32 and 33, the return spring 61 has lost its elastic force to press the playing cards 1. However, since the card pressing wheel set 62 of the card pressing arm 60 gradually approaches the magnetic element 64 as the number of playing cards 1 decreases, and the magnetic element 64 has different magnetic forces and will produce magnetic fields of different ranges, a suitable magnetic force can be selected. The magnetic component 64 is used. When the number of playing cards 14 decreases and the card pressing wheel set 62 enters the magnetic field range of the magnetic component 64, the magnetic component 64 attracts the magnetic wheel 63 to increase the force of the card pressing wheel set 62 pressing against the playing cards 1. The fewer the number of playing cards 1, the weaker the elastic force of the return spring 61. On the contrary, the magnetic component 64 has a stronger suction force on the magnetic wheel 63, thereby assisting the card pressing arm 60 to maintain an appropriate pressure path for fewer playing cards 1, so that the playing cards 1 can be effectively transferred by the card transfer wheel set 36 to the central lifting platform 37 of the central containing groove 31, thereby achieving the practical effect of increasing friction to ensure smooth transfer without idling.
