Two card-out channels 4213, a card-turning part 4209 for opening or closing the card-turning channel 4224 or the exit of the first card-out channel 4208 is arranged near the first card-out channel 4208, when the card-turning part 4209 closes the card-turning channel 4224 or opens When the first card-out channel 4208 exits, the card-in channel 4103, the transport channel and the first card-out channel 4208 are connected in sequence, and when the card-turning part 4209 opens the card-turning channel 4224 and closes the first card-out channel 4208 exit, the card-in channel 4103, the conveying channel, the first card-discharging channel 4208, the card-turning channel 4224 and the second card-discharging channel 4213 are connected in sequence. The card-distributing mechanism is installed at the card-in channel of the card-distributing device 42 , the delivery mechanism is installed at the position of the delivery channel, and the card-turning mechanism is installed between the first card-out channel 4208 and the second card-out channel 4213 .

The card-splitting mechanism can adopt various card-splitting structures disclosed in CN108525278A, CN105854274A and other series of patent documents, but although these card-splitting structures can better separate the incoming playing cards to ensure that single cards pass through, it is difficult to let the cards that have entered the conveyance The poker cards in the channel are withdrawn from the card-in channel (retirement), so once the subsequent sensor detects that two poker cards overlap and needs to withdraw the poker cards and send the card notification for re-distribution, there will be a problem of difficulty in withdrawing the cards. In order to overcome this technical problem, in the present embodiment, the card distribution mechanism preferably has the following structure:

As shown in Fig. 9 to Fig. 12, comprise baffle plate 4105, send card wheel 4201, divide card wheel 4202 and divide card pressing wheel 4222, be used for pushing playing cards to the card delivery wheel 4201 of card delivery device 42 entering card channel Installed on the bottom of the card storage box 41, the bottom of the shield plate 4105 is provided with a card splitting roller 4222, and the card splitting wheel 4222 is arranged below the card splitting wheel 4202. The one-way clutch mechanism realizes that the cards can be rotated without turning. In this way, not only can the rapid and effective card splitting effect be realized when the cards are entered, but also when the cards need to be withdrawn, the card splitting pressure wheel 4222 can be reversed together with the card splitting wheel 4202 to realize fast and reliable card withdrawal, avoiding the difficulty of card withdrawal. Further preferably, the splitting press wheel 4222 and the splitting wheel 4202 are misplaced and overlapped up and down (that is, the splitting pinch wheel 4222 and the splitting wheel 4202 are staggered by a horizontal distance and the splitting pinch wheel 4222 is closer to the axis of the splitting wheel 4202 Close to the card storage space of the card storage box 41, the bottommost part of the card distribution press wheel 4222 is lower than the highest point of the card distribution wheel 4202), like this, when the gap between the card distribution pressure wheel 4222 and the card distribution wheel 4202 enters a plurality of playing cards When playing cards, the entry end of the playing cards will be tilted so that the upper and lower playing cards will be shifted, thus avoiding the electrostatic bonding of the upper and lower playing cards and the inability to separate them, because the card splitting pressure wheel 4222 is controlled by the one-way clutch mechanism and cannot rotate. In this way, the static friction force between the splitting press wheel 4222 and the playing cards above is far greater than the friction between the upper and lower two playing cards, and the conveying power of the playing cards comes from the splitting wheel 4202, which is applied to the playing cards below Yes, so, the lower playing cards are conveyed and continue to move forward, the upper playing cards are temporarily detained, and the upper and lower playing cards are separated. The separation speed is fast, the structure is simple, the maintenance is convenient, and the accuracy is high.

In order to further enhance the card-splitting effect of the above-mentioned card-splitting mechanism, several card-in ribs 4104 are provided at the bottom of the card-shielding plate 4105, and a number of ribs are formed on the bottom inner wall of the card storage box 41 between the card delivery wheel 4201 and the card-splitting wheel 4202. A card-advancing protrusion 4102, and a card-advancing rib 4104 is closer to the card-sharing press wheel 4222 relative to the card-advancing protrusion 4102, so that a card-advancing protrusion 4102, a card-advancing rib 4104 and the card-dividing wheel 4202 are formed The board-in channel 4103 of the card-distributing device 42, the card-in channel 4103 is a concave structure with two ends (the card-incoming protrusion 4102 and the card-distributing wheel 4202) raised in the middle, so that the card-in channel with concave and convex cooperation helps to overlap Squeeze and rub the multiple playing cards of the card and separate them to ensure that the multiple playing cards that enter the positions of the card-splitting wheel 4202 and the card-splitting press wheel 4222 are separated from each other. In addition, because the card-entry protrusion 4102 will move the cards in the card storage box 41 The jacking is outside the card entry channel 4103, so when withdrawing the cards, the poker cards withdrawn from the card entry channel will be inserted under the poker cards in the card storage box 41, so as to avoid the difficulty of pushing cards caused by the offset of two poker cards. Further preferably, a plurality of card-introducing protrusions 4102 and a plurality of card-introducing ribs 4104 are alternately arranged to obtain a better card-shuffling separation effect.

In this embodiment, one side of the card delivery wheel 4201 protrudes to form arc-shaped sawtooth, so that the playing cards can be pushed upward and forward during the rotation of the card delivery wheel 4201, so that the playing cards can better cross the card convex 4102, in addition, this action also can avoid front and rear poker cards from being blocked when the card dealing device withdraws the cards. The card-splitting press wheel 4222 is passively rotated in one direction. In order to facilitate adjustment, the card-scoring press wheel 4222 is installed on the bottom of the shield plate 4105 through an elastic pressing mechanism. The elastic pressing mechanism is a compression spring and a push rod 4221, and the one-way clutch Mechanism is the one-way clutch that is installed on the axle of dividing plate pressing wheel 4222. The components of the card-splitting wheel, the card-sending wheel and the card-splitting press wheel, each component can be a roller part, or can be composed of a plurality of wheel-shaped parts installed on the same shaft, for example, as shown in the figure 16. As shown in Figure 17, each card splitting wheel 4202 includes a support frame with a certain rigidity and a rubber ring sleeved and fixed on the support frame. Part of the arc-shaped circumference of the rubber ring is protruding for contact with playing cards The arc-shaped rubber sawtooth of the rubber ring, the circumference of the part other than the arc-shaped rubber sawtooth of the rubber ring is lower than the circumference of the side wall of the support frame, so that when the arc-shaped rubber sawtooth part of the card-distributing wheel contacts with the playing cards, the friction force is greater and it is easier to drive the playing cards. Cards move, 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 driving the playing cards to move helps to separate the two playing cards. Four card-distributing wheels 4202 are installed on the same card-distributing wheel shaft 42021, and the card-advancing rib 4104 and the card-distributing pressure wheel 4222 at the bottom of the baffle plate 4105 are arranged alternately with the four card-distributing wheels 4202 up and down, so that it is convenient to adjust up and down Gaps for fast and efficient card splitting. The card sending wheel shaft 42011 of the card sending wheel 4201 and the card splitting wheel shaft 42021 of the card splitting wheel 4202 are connected by the card transmission belt 4228 transmission, so as to realize the cooperative rotation of the card sending wheel 4201 and the card splitting wheel 4202, to improve the card splitting efficiency and Split effect.

As shown in Figures 9 to 12, the conveying mechanism includes a first conveying wheel 4203 and a second conveying wheel 4205 installed on the conveying bottom wall 4204 of the conveying channel, and a first conveying wheel 4205 installed on the conveying top wall 4218 of the conveying channel. The pressure roller 4219 and the second conveying roller 4217, the first conveying roller 4219 cooperates with the first conveying wheel 4203 up and down, the second conveying roller 4217 cooperates with the second conveying roller 4205 up and down, the first conveying roller 4219 and the second conveying roller The delivery pressure wheel 4217 is a driven wheel, the first delivery wheel 4203 and the second delivery wheel 4205 are driving wheels and are sleeved with rubber rings to increase friction, the first delivery wheel shaft 42031 of the first delivery wheel 4203, the second delivery wheel 4205 The second conveying wheel shaft 42051 of the second conveying wheel shaft 42051, the card-splitting wheel shaft 42021 of the card-splitting wheel 4202 and the card-sending motor shaft 42201 of the card-sending motor 4220 are connected by the transmission drive belt 4225 of the distribution card, and the transmission belt 4225 of the card distribution is tensioned by the tension pulley 4226, thus realizing Synchronized movement of card feeding, card splitting and conveying. The first conveying wheel 4203, the second conveying wheel 4205, the first conveying pressure roller 4219, and the second conveying pressure roller 4217 can be press-fitted up and down, or can be staggered and staggered up and down. It can be a roller part, or it can be composed of several wheel parts mounted on the same shaft.

As shown in Fig. 13 and Fig. 19, the conveying channel of the above-mentioned card dealer is provided with an identification element for identifying the front and back of the playing cards and a plurality of detection elements for detecting the playing cards.

Regarding the identification of the front and back of playing cards in the conveying channel: one method is to obtain photo information of different positions on the same side of playing cards, and use the pattern on the back of the playing cards as a unit pattern. The degree of coincidence determines whether the playing card is front or back. Another method is to identify the front and back of the playing cards by distinguishing the character patterns on the fixed diagonal positions of the playing cards according to the characteristic that the fixed positions on the oblique corners of the front of the playing cards must have characters, such as Kou Yongjun In 2007, he published a master's thesis titled "Application Research of Image Recognition on Card Dealing Machine" in Hunan University Journal. Another method is to print magnetic ink at a fixed position on the front or back of the playing card, and identify the front and back of the playing card by detecting the magnetic ink. For the first two identification methods, the identification element is a camera. For the third identification method, the identification element is a magnetic detection sensor.

About identifying whether the playing cards in the conveying channel overlap: one method is to detect the length of the playing cards. When the detection element detects that the playing cards in the conveying channel are longer than the normal length, it can be determined that there are multiple playing cards overlapping. Another method is to detect the thickness of the playing cards. When the detection element detects that the thickness of the playing cards in the card-in channel, the delivery channel or the first card-out channel is greater than the normal thickness, it can be determined that there are multiple playing cards overlapping. One or more methods may be used in the same dealing device.

When it is recognized that the playing cards in the conveying channel do not need to be turned over, the card turning mechanism will issue the playing cards directly; When it is recognized that the playing cards need to be withdrawn from the card delivery device, the card delivery motor 4220 drives the first delivery wheel 4203, the second delivery wheel 4205, the card distribution wheel 4202 and the card delivery wheel 4201 to reversely implement the card withdrawal. One or more methods may be used in the same dealing device.

The utility model recognizes the front and back of the playing cards in the conveying channel, and turns over the playing cards in the turning channel. The two steps do not affect each other, and the cards can be turned and dealt continuously, which greatly improves the efficiency and efficiency of turning cards. Licensing efficiency.

As shown in Figure 13, in the present embodiment, the identification element used to identify the front and back of the playing cards is a camera 4238, and the camera 4238 and a detection sensor for detecting that the playing cards are in place are fixed on the delivery bottom wall 4204 or the delivery top of the delivery channel On the wall 4218, when the detection sensor detects the playing cards, start the camera at the same time or after a delay, so that the camera can just capture the pattern information on the diagonally fixed position of the playing cards in the conveying channel, so that the controller can identify them according to the pattern information The front and back of a playing card, such as when it is recognized as a character pattern, is determined to be the front.

In order to ensure that the camera can be started in time and take a panoramic view of the character patterns on the playing cards, the following settings are preferred:

In the first case, the playing cards are conveyed forward along the width side in the card delivery device (that is, the width of the conveying channel is close to the width of the playing cards). In this way, the preferred value range of the width B of the conveying channel is: playing card width+1mm<B<playing card width+5mm.

The value range of the vertical distance M between the center of the camera lens and the adjacent left or right side wall of the conveying channel is: the vertical distance between the character pattern of the playing card and its near side edge<M<the distance of the character pattern of the playing card The vertical distance of its proximal side edge +5mm.

The value range of the vertical distance H between the lens center of the camera and the playing cards in the conveying channel is: 10mm<H<15mm.

Take commonly used playing cards (Bridge Size length 8.8cm width 5.7cm) as an example, 58mm<B<62mm, 6mm<M<12mm.

In the second case, the playing cards are conveyed forward along the length side in the card delivery device (that is, the width of the conveying channel is close to the length of the playing cards). In this way, the preferred value range of the width B of the conveying channel is: length of playing cards+1mm<B<length of playing cards+5mm.

The value range of the vertical distance M between the center of the camera lens and the adjacent left or right side wall of the conveying channel is: the vertical distance between the character pattern of the playing card and its near side edge<M<the distance of the character pattern of the playing card The vertical distance of its proximal side edge +5mm.

The value range of the vertical distance H between the lens center of the camera and the playing cards in the conveying channel is: 10mm<H<15mm.

Take common playing cards (Bridge Size length 8.8cm width 5.7cm) as an example, 89mm<B<93mm, 6mm<M<12mm.

In other embodiments, the playing cards in the conveying channel can also be transported to the left or right side close to the edge through the specific conveying mode, speed and direction, so that the width of the conveying channel will not affect the camera's Setting, only need to be limited: the vertical distance M between the lens center of the camera and its adjacent left or right side wall of the conveying channel is: the vertical distance between the character pattern of the playing card and its near side edge<M< The vertical distance between the character pattern of the playing card and its near side edge is +5mm. Take common playing cards (Bridge Size length 8.8cm width 5.7cm) as an example, 6mm<M<12mm. The value range of the vertical distance H between the lens center of the camera and the playing cards in the conveying channel is: 10mm<H<15mm.

This can not only avoid unnecessary friction between the playing cards and the side wall of the conveying channel, but also ensure that when the playing cards are tilted in the conveying channel, the camera can still capture a panoramic view of the position of the characters of the playing cards.

In addition, in order to avoid or reduce the influence of uncertain factors such as the advancing speed of the playing cards in the conveying channel, it is preferable to set the detection sensor for detecting that the playing cards are in place and the camera 4238 adjacent to the left and right, so that after the detection sensor detects that the playing cards are in place, The camera activates instantly to capture a panoramic view of the location of the playing card characters. In other embodiments, it is also preferable to set two cameras in the conveying channel, these two cameras are respectively close to the left side wall and the right side wall of the conveying channel, and the recognition can be taken by multiple cameras to improve the accuracy of the identification of the front and back of playing cards and recognition efficiency.

It should be noted that the width of the above-mentioned conveying channel refers to the effective width that can transport playing cards in the conveying channel, and the left or right side wall of the above-mentioned conveying channel refers to the theoretical left or right wall of the effective width. , in a feasible implementation manner, the left side wall or the right side wall of the delivery channel can be a visible structure formed by a limiting component, a limiting structure, a wall surface of the housing, etc., or it can be a non-visible structure but actually exists, For example, by controlling the conveying mode, speed, and direction of the conveying wheel/roller, the reachable range of playing cards is limited to a specific range in the conveying channel, and the left and right boundaries of the specific range are regarded as the left side of the conveying channel wall or right side wall.

As shown in Figure 19, in this embodiment, a first sensor 4235, a second sensor 4236, and a third sensor 4237 are sequentially installed on the transport top wall 4218 or the transport bottom wall 4204 of the transport channel along the advancing direction of the playing cards. A sensor 4235 and the third sensor 4237 cooperate to detect the length distance that playing cards cover simultaneously in the delivery channel to judge whether there is a state of overlapping of multiple playing cards, if the first sensor 4235 and the third sensor 4237 are blocked simultaneously (pokers are detected card), then it is determined that two partially overlapped playing cards enter the conveying channel, and the card delivery motor 4220 reverses and returns the playing cards to the card storage box 41 for re-advancement.

For the situation that the playing cards are conveyed forward along the width side in the card delivery device (that is, the width of the conveying channel is close to the width of the playing cards), the distance between the first sensor 4235 and the third sensor 4237 is larger than the length of the playing cards 2mm-3mm.

For the situation that the playing cards are conveyed forward along the length side in the card delivery device (that is, the width of the conveying channel is close to the length of the playing cards), the distance between the first sensor 4235 and the third sensor 4237 is larger than the width of the playing cards 2mm-3mm.

The second sensor 4236 is arranged between the first sensor 4235 and the third sensor 4237, and when it is blocked (playing cards are detected), the card turning motor 4230 is started to turn over cards as required. The second sensor 4236 can also cooperate with the first sensor 4235 and the third sensor 4237 to assist in judging whether there are multiple partially overlapping playing cards.

In this way, after passing through the first sensor, the camera takes pictures of the single playing card separated by the card separating mechanism to identify the front and back sides. When the playing card continues to move forward along the channel to the position of the second sensor, the turning mechanism is controlled according to the recognition result. Whether to flip the playing cards. If the first sensor is blocked until the third sensor is also blocked at the same time (that is, continuously detects playing cards), it means that two playing cards partially overlap and enter the conveying channel, and the card delivery motor starts to reverse, and will enter the card feeding channel. The playing cards are returned to the card storage box to separate the individual cards again, so as to ensure the accuracy of the number of cards dealt.
