Further preferably, the plurality of card feeding protrusions 4102 and the plurality of card feeding protrusions 4104 are alternately arranged to obtain a better card rubbing separation effect.

The dealing device 42 includes a card distributing mechanism, a conveying mechanism and a card turning mechanism, and the channels for passing playing cards in the dealing device 42 include a card feeding channel 4103, a conveying channel, a card turning channel 4224, a first card discharging channel 4208 and a second card discharging channel 4213, a card turning component 4209 for opening or closing the card turning channel 4224 or the outlet of the first card discharging channel 4208 is arranged near the first card discharging channel 4208, when the card turning component 4209 closes the card turning channel 4224 or opens the outlet of the first card discharging channel 4208, the card feeding channel 4103, the conveying channel and the first card discharging channel 4208 are sequentially connected, and when the card turning component 4209 opens the card turning channel 4224 and closes the outlet of the first card discharging channel 4208, the card feeding channel 4103, the conveying channel, the first card discharging channel 4208 and the second card discharging channel 4213 are sequentially connected. The card distributing mechanism is mounted at the card infeed channel of the card dealing arrangement 42, the transport mechanism is mounted at the transport channel position, and the card flipping mechanism is mounted between the first card discharge channel 4208 and the second card discharge channel 4213.

The card distributing mechanism can adopt various card distributing structures disclosed in CN108525278A, CN105854274A and other series of patent documents, but the card distributing structures can better separate the entering playing cards to ensure single cards to pass, but the playing cards which have entered the conveying channel are difficult to withdraw (return) from the card feeding channel, so that the problem of card returning difficulty occurs once a subsequent sensor detects that two playing cards overlap and the playing cards need to be returned to the card feeding notification for re-distributing. To overcome this technical problem, in this embodiment, the card distributing mechanism preferably has the following structure:

As shown in fig. 9 to 12, the card feeding device comprises a card blocking plate 4105, a card feeding wheel 4201, a card distributing wheel 4202 and a card distributing wheel 4222, wherein the card feeding wheel 4201 for pushing playing cards to a card feeding channel of the card distributing device 42 is arranged at the bottom of the card storage box 41, the card distributing wheel 4222 is arranged at the bottom of the card blocking plate 4105, the card distributing wheel 4202 is arranged below the card distributing wheel 4222, the card distributing wheel 4202 is driven to rotate by a card distributing motor, and the card feeding wheel 4222 can rotate by realizing that the playing cards are fed without rotating and returning through a one-way clutch mechanism. Thus, not only can the effect of rapid and effective card distribution be realized when the cards are fed, but also the card distribution pinch roller 4222 can be reversely rotated together with the card distribution wheel 4202 to realize rapid and reliable card distribution when the cards are required to be returned, thereby avoiding the difficulty of card return. Further preferably, the card distributing wheel 4222 and the card distributing wheel 4202 are staggered back and forth and are designed in an up-and-down overlapping manner (i.e. the axes of the card distributing wheel 4222 and the card distributing wheel 4202 are staggered by a horizontal distance and the card distributing wheel 4222 is closer to the card storage space of the card storage box 41 than the axes of the card distributing wheel 4202, and the bottommost part of the card distributing wheel 4222 is lower than the highest part of the card distributing wheel 4202), so that when the gap between the card distributing wheel 4222 and the card distributing wheel 4202 enters a plurality of playing cards, the entering ends of the playing cards are tilted, so that the upper playing card and the lower playing card are shifted, the electrostatic adhesion of the upper playing card and the lower playing card is avoided, and the upper playing card and the lower playing card are separated temporarily, because the card distributing wheel 4222 is controlled by the unidirectional clutch mechanism and the static friction force between the card distributing wheel 4222 and the upper playing card is far greater than the friction force between the upper playing card and the lower playing card, and the conveying power of the playing card is from the card distributing wheel 4202 and is applied to the playing card below playing card, so that the lower playing card is conveyed and moves forwards, the upper playing card and the lower playing card is kept temporarily separated, and the upper playing card and the lower playing card is easy, and the playing card and the playing card storage device is convenient.

In order to further improve the card distributing effect of the card distributing mechanism, a plurality of card feeding convex edges 4104 are arranged at the bottom of the card blocking plate 4105, a plurality of card feeding convex edges 4102 are formed on the inner wall of the bottom of the card storage box 41 between the card feeding wheel 4201 and the card distributing wheel 4202, the card feeding convex edges 4104 are closer to the card distributing wheel 4222 than the card feeding convex edges 4102, so that a card feeding channel 4103 of the card distributing device 42 is formed among the card feeding convex edges 4102, the card feeding channel 4104 and the card distributing wheel 4202, the card feeding channel 4103 is provided with a concave structure with two ends (the card feeding convex edges 4102 and the card distributing wheel 4202) tilting and concave-convex, so that the overlapped plurality of cards are squeezed and rubbed and separated, and the plurality of playing cards entering the card distributing wheel 4202 and the card distributing wheel 4222 are ensured to be separated front and back, in addition, because the card feeding convex edges 4102 can lift the playing cards in the card storage box 41 outside the card feeding channel 4103, and the playing cards can be prevented from being pushed against the card storage box 41 when the playing cards are withdrawn from the card feeding channel. Further preferably, the plurality of card feeding protrusions 4102 and the plurality of card feeding protrusions 4104 are alternately arranged to obtain a better card rubbing separation effect.

In this embodiment, an arc saw tooth is formed on one side of the card feeding wheel 4201 in a protruding manner, so that playing cards can be pushed upwards and forwards in the rotation process of the card feeding wheel 4201, so that the playing cards can better span the card feeding protrusion 4102, and in addition, the action can also avoid the situation that the front playing card and the rear playing card are blocked when the card dealing device moves back. The card dividing pinch roller 4222 is passively rotated in one direction, and for convenience in adjustment, the card dividing pinch roller 4222 is mounted at the bottom of the card baffle 4105 through an elastic pressing mechanism, the elastic pressing mechanism is a pressure spring and a push rod 4221, and the one-way clutch mechanism is a one-way clutch mounted on the shaft of the card dividing pinch roller 4222. The card distributing wheel, the card feeding wheel and the card distributing pinch roller may be one roller part or may be multiple wheel parts mounted on the same shaft, for example, as shown in fig. 16 and 17, each card distributing wheel 4202 includes a supporting frame with a certain rigidity strength and a rubber ring sleeved on the supporting frame, part of the arc circumference of the rubber ring is a protruding arc rubber saw tooth for contacting with the playing cards, and part of the arc circumference of the rubber ring outside the arc rubber saw tooth is lower than the side wall circumference of the supporting frame, so that when the arc rubber saw tooth part of the card distributing wheel contacts with the playing cards, friction force is larger, thereby driving the playing cards to move relatively easily, and when the side wall circumference of the supporting frame of the card distributing wheel contacts with the playing cards, friction force is smaller, thereby driving the playing cards to move relatively difficultly, and the gap type driving of the playing cards to move is beneficial to separation of the two playing cards. Four card distributing wheels 4202 are arranged on the same card distributing wheel shaft 42021, and card feeding convex edges 4104 and card distributing pressing wheels 4222 at the bottom of the card blocking plate 4105 are arranged in a staggered mode up and down with the four card distributing wheels 4202, so that upper and lower gaps can be conveniently adjusted, and fast and effective card distributing can be realized. The card feeding wheel shaft 42011 of the card feeding wheel 4201 is in transmission connection with the card distributing wheel shaft 42021 of the card distributing wheel 4202 through the card feeding transmission belt 4228, so that the card feeding wheel 4201 and the card distributing wheel 4202 are matched to rotate, and card distributing efficiency and card distributing effect are improved.

As shown in fig. 9 to 12, the conveying mechanism includes a first conveying wheel 4203 and a second conveying wheel 4205 mounted on a conveying bottom wall 4204 of the conveying channel, and a first conveying wheel 4219 and a second conveying wheel 4217 mounted on a conveying top wall 4218 of the conveying channel, the first conveying wheel 4219 being engaged up and down with the first conveying wheel 4203, the second conveying wheel 4217 being engaged up and down with the second conveying wheel 4205, the first conveying wheel 4219 and the second conveying wheel 4217 being driven wheels, the first conveying wheel 4203 and the second conveying wheel 4205 being driving wheels and being sleeved with rubber rings to increase friction, a first conveying wheel shaft 42031 of the first conveying wheel 4203, a second conveying wheel shaft 42051 of the second conveying wheel 4205, a card distributing wheel shaft 42021 of the card distributing wheel 4202, and a card distributing motor 42201 of the card distributing motor 4220 being drivingly connected by a card distributing belt 4225, the card distributing motor shaft 4225 being tensioned by a tensioning wheel 4226, so that synchronous movement of feeding, distributing and conveying is achieved. The first conveying wheel 4203, the second conveying wheel 4205, the first conveying pinch roller 4219 and the second conveying pinch roller 4217 may be in vertically opposite press fit, or in vertically staggered fit, and each component may be a roller part or a plurality of wheel parts mounted on the same shaft.

As shown in fig. 13 and 19, the conveying path of the card dispenser is provided with a recognition element for recognizing the front and back sides of the playing card and a plurality of detection elements for detecting the playing card.

The method is to acquire photo information of different positions on the same side of the playing card, and determine whether the playing card is the front side or the back side according to the pattern overlapping degree of the photos by utilizing the rule that the overlapping degree of the unit patterns of the back side of the playing card is high in four-side continuous positions. Another method is to identify the front and back sides of the playing card by distinguishing the character pattern on the diagonally opposite fixed position of the playing card according to the characteristic that the fixed position on the diagonally opposite corner of the front side of the playing card is necessarily provided with characters, for example, kou Yongjun a published in the university of Hunan school bulletin in 2007 is a 'national institute of image recognition on card dealer'. Still another method is to print magnetic ink on the front or back of the playing card at a fixed location, and to identify the front or 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.

One method for identifying whether there is an overlap of playing cards in the feed path is to detect the length of the playing cards, and when the detecting element detects that the length of the playing cards in the feed path is longer than the normal length, it is determined that there is an overlap of a plurality of playing cards. Another method is to detect the thickness of the playing cards, and when the detecting element detects that the thickness of the playing cards in the card feeding channel, the conveying channel or the first card discharging channel is larger than the normal thickness, the detecting element can determine that a plurality of playing cards are overlapped. One or more methods may be employed in the same card dealing arrangement.

When the playing cards in the conveying channel are identified to be required to be overturned, the card overturning mechanism directly sends out the playing cards, and when the playing cards in the conveying channel are identified to be required to be overturned, the card overturning mechanism overturns the playing cards and sends out the playing cards. When it is recognized that playing cards need to exit the card dealing arrangement, the card dealing motor 4220 drives the first transport wheel 4203, the second transport wheel 4205, the card distributing wheel 4202, and the card feeding wheel 4201 to reverse rotation for card withdrawal. One or more methods may be employed in the same card dealing arrangement.

The invention identifies the front and the back of the playing cards in the conveying channel, and turns the playing cards in the card turning channel, the two steps are not mutually influenced, the playing cards can be continuously turned and dealt, and the card turning efficiency and the card dealing efficiency are greatly improved.

As shown in fig. 13, in this embodiment, the identification element for identifying the front and back sides of the playing card is a camera 4238, the camera 4238 and a detection sensor for detecting the position of the playing card are fixed on the conveying bottom wall 4204 or the conveying top wall 4218 of the conveying channel, and when the detection sensor detects the playing card, the camera is started simultaneously or with a delay, so that the camera just can shoot the pattern information on the diagonally opposite fixed position of the playing card in the conveying channel, and thus the controller can identify the front and back sides of the playing card according to the pattern information, for example, when the controller identifies the character pattern, the controller determines that the playing card is front.

In order to ensure that the camera can timely start and shoot the panorama of the character patterns on the playing card, the following settings are preferable:

In the first case, the playing cards are transported forward along the width edge within the card dealing arrangement (i.e., the width of the transport path is close to the width of the playing cards). Thus, the preferred range of values for the width B of the feed channel is playing card width +1mm < B < playing card width +5mm.

The vertical distance M between the center of the lens of the camera and the left side wall or the right side wall of the adjacent conveying channel is the vertical distance M between the character pattern of the playing card and the near side edge of the playing card is less than +5mm.

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

Taking a common playing card (Bridge Size length 8.8cm and width 5.7 cm) as an example, 58mm < B <62mm,6mm < M <12mm.

In the second case, the playing cards are transported forward along the length edge within the card dealing arrangement (i.e., the width of the transport path is close to the length of the playing cards). Thus, the preferred range of values for the width B of the feed channel is playing card length+1 mm < B < playing card length+5 mm.

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

In other embodiments, the playing cards in the conveying channel can be conveyed towards the left side or the right side by a specific conveying mode, speed and direction, so that the width of the conveying channel can not influence the arrangement of the camera, and the value range of the vertical distance M between the center of the lens of the camera and the left side wall or the right side wall of the adjacent conveying channel is limited to be that the vertical distance M between the character pattern of the playing card and the near side edge of the playing card is less than the vertical distance +5mm between the character pattern of the playing card and the near side edge of the playing card. Taking the common playing card (Bridge Size length 8.8cm and width 5.7 cm) as an example, 6mm < M <12mm. The vertical distance H between the center of the lens of the camera and the playing card in the conveying channel is 10mm < H <15mm.

Therefore, unnecessary scratch obstruction of the playing cards and the side wall of the conveying channel can be avoided, and the camera can still shoot the panorama of the character position of the playing cards under the condition that the playing cards incline in the conveying channel.

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 that a detection sensor for detecting the in-place position of the playing cards and the camera 4238 are adjacently arranged on the left and right sides, so that the camera is started immediately after the detection sensor detects the in-place position of the playing cards, and the panorama of the character positions of the playing cards can be shot. In other embodiments, two cameras can be preferably arranged in the conveying channel, and the two cameras are respectively close to the left side wall and the right side wall of the conveying channel, and the accuracy and the recognition efficiency of the front and the back of the playing card are improved through shooting and recognition by the plurality of cameras.

The width of the conveying channel refers to the effective width of the playing card that can be conveyed in the conveying channel, the left side wall or the right side wall of the conveying channel refers to the theoretical left side wall or the right side wall of the effective width, and in a feasible embodiment, the left side wall or the right side wall of the conveying channel may be a visible structure formed by a limiting member, a limiting structure, a shell wall surface or the like, or may be a non-visible structure, but the visible structure is also a non-visible structure, for example, the conveying mode, the speed, the direction or the like of the conveying wheel/roller are controlled to limit the reach of the playing card within a specific range in the conveying channel, and the left side wall or the right side wall of the specific range is regarded as the left side wall or the right side wall of the conveying channel.

As shown in fig. 19, in this embodiment, a first sensor 4235, a second sensor 4236 and a third sensor 4237 are mounted on the conveying top wall 4218 or the conveying bottom wall 4204 of the conveying channel in order along the advancing direction of the playing cards, and the first sensor 4235 and the third sensor 4237 cooperate to detect the length distance covered by the playing cards in the conveying channel simultaneously to determine whether there is a state of overlapping of a plurality of playing cards, and if the first sensor 4235 and the third sensor 4237 are shielded simultaneously (detect playing cards), it is determined that two playing cards with partial overlapping enter the conveying channel, and the card dealing motor 4220 is reversed to retract the playing cards into the card storage box 41 for re-feeding and dividing the playing cards.

For the case where playing cards are being transported forward along the width edge within the card dealing arrangement (i.e., the width of the transport path is close to the width of the playing cards), the first sensor 4235 and the third sensor 4237 are 2mm-3mm greater than the length of the playing cards.

For the case where playing cards are being transported forward along the length of the card dealing arrangement (i.e., the width of the transport path is close to the length of the playing cards), the first sensor 4235 and the third sensor 4237 are 2mm-3mm greater than the width of the playing cards.

The second sensor 4236 is disposed between the first sensor 4235 and the third sensor 4237, and when it is blocked (playing card is detected), the card flipping motor 4230 is started to perform card flipping as needed. The second sensor 4236 may also cooperate with the first sensor 4235 and the third sensor 4237 to assist in determining whether there are partially overlapping playing cards.

Thus, after the single playing cards separated by the card separating mechanism pass through the first sensor, the camera shoots to perform front and back recognition, and when the playing cards continue to move forward along the channel to the position of the second sensor, the card turning mechanism is controlled to turn over the playing cards according to the recognition result. If the first sensor is shielded until the third sensor is shielded (namely, the playing cards are continuously detected), two playing cards are partially overlapped and enter the conveying channel, the card dealing motor starts to rotate reversely, and the playing cards entering the card moving channel are returned to the card storage box to be separated again, so that the accuracy of the number of the playing cards dealt is ensured.
