Description

[0002] Current card sorting machines generally include mahjong machines, domino machines, etc., which mainly sort out entertainment cards, save users time, and enhance the entertainment value.

[0003] Existing card sorting machines mainly fall into two categories: magnetic and non-magnetic. For magnetic methods, both the card manufacturing process and the machine's structure are relatively complex and costly. For non-magnetic methods, the structure is simpler. During the rotation of the shuffling disc, the cards move towards the edge under the influence of rotation and centrifugal force, and are then conveyed to a conveying mechanism via card feeding channels around the disc's edge. The conveying mechanism then transports the cards to subsequent processes until a lifting mechanism ejects them from the machine for user use.

[0004] In existing technologies, during the rotation of the shuffling disc, a card-pulling strip is usually used to move the cards to achieve the purpose of shuffling and moving the cards to the periphery of the shuffling disc.

[0032] Example 1: Refer to Figure 1 As shown in Figure 6(d), this embodiment of the invention provides a card sorting machine card picking device, which is applied in a card sorting machine. The card sorting machine card picking device includes a shuffling plate 10, a card feeding channel 20, a card blocking component 30, and a card picking component 40.

[0033] The shuffling plate 10 has a card delivery channel 20 around its perimeter. The side of the card delivery channel 20 away from the shuffling plate 10 has a channel sidewall 21, and the side of the card delivery channel 20 closer to the shuffling plate 10 is connected to the shuffling plate 10.

[0034] There are four blocking components 30, each of which spans across its corresponding card delivery channel 20. The distance between the blocking component 30 and the bottom surface of the card delivery channel 20 is greater than the height of the card body 90 and less than the width of the card body 90.

[0035] There are four card pickers 40, each located in front of its corresponding card blocker 30. Each card picker 40 gives the card body 90a in the first state on the card delivery channel 20 the tendency to move towards the shuffling plate 10.

[0036] Typically, the shuffling disc 10 is rotatable, rotating clockwise or counterclockwise around a vertical axis. During the rotation of the shuffling disc 10, external forces, such as the card-pushing strip 50 or other components, shuffle the cards and drive the cards 90 to the periphery of the shuffling disc 10. The card-feeding channels 20 around the shuffling disc 10 gradually feed the cards 90 to the conveying mechanism 80, which is connected to the card-feeding channels 20. The conveying mechanism 80 then sends the cards 90 to subsequent processes such as flipping, stacking, and pushing cards.

[0037] Reference Figure 1 and Figure 2 In this invention, a card-blocking component 30 is installed across the card-feeding channel 20, and the open structure inside the card-feeding channel 20 serves as the connection port to the shuffling plate 10. Because the distance between the card-blocking component 30 and the bottom surface of the card-feeding channel 20 is greater than the height of the card body 90 but less than the width of the card body 90, it is designed with reference to... Figure 1 Horizontal cards 90 can continue to be conveyed to the conveying structure through the card-blocking component 30, while vertical cards or cards stacked together, due to their height, are blocked by the card-blocking component 30, causing the vertical cards or cards stacked on top to fall back from the connecting opening to the shuffling tray 10, as shown in the reference. Figure 1 and Figure 2 This causes the cards delivered by the card delivery channel 20 to be in a horizontal state and be a single card. Consequently, the cards delivered by the card delivery channel 20 90 are in a one-dimensional horizontal single card state.

[0038] In this embodiment, the card picker 40 is located on the side of the card delivery channel 20 near the shuffling plate 10. The card picker 40 gives the card body 90 a tendency to move towards the shuffling plate 10 by acting on the front side of the card body 90.

[0039] Specifically, refer to Figure 4 As shown in Figure 6(d), the card picking component 40 of this embodiment includes a card picking block 41. The card picking block 41 is rotatable and its rotation direction is opposite to the rotation direction of the shuffling disc 10. That is, when the shuffling disc 10 rotates clockwise, the card picking block 41 rotates counterclockwise. The shortest distance between the card picking block 41 and the channel sidewall 21 is greater than the width of the card body 90 and less than the length of the card body 90. When the card picking block 41 rotates, it contacts the front side of the card body 90a in the first state and drives the card body 90a to move towards the shuffling disc 10.

[0040] Reference Figure 4 Let the length of the card body 90 be L, the width be W, and the height be H. Let the shortest distance between the card piece 41 and the side wall 21 of the passage be a. Then, a > W and a < L.

[0041] Since the card picker 40 is located in front of the card blocker 30, when the cards 90 are sent from the shuffling plate 10 to the card delivery channel 20, they first pass through the card blocker 30, leaving cards in a horizontal state, namely card 90a in the first state and card 90b in the second state. Since a > W and a < L, therefore refer to... Figure 4 The card 90b in the second state will not be blocked by the card picker 41 and can pass smoothly through the card delivery channel 20. The card 90a in the first state will be blocked by the card picker 41. Since the card picker 41 rotates in the opposite direction to the shuffling plate 10, referring to Figures 5(a) to 5(d), after the card picker 41 contacts the front side of the card 90a, it gradually picks the card 90a from the outside to the inside until it is picked back to the shuffling plate 10. Therefore, under the action of the card picker 41, all the cards delivered through the card delivery channel 20 are the card 90b in the second state.

[0042] Since the card-picking block 41 is rotatable and its rotation direction is opposite to that of the shuffling plate 10, a > W and a < L, the card-picking block 41 can not only pick up the cards 90a located on its side and return them to the shuffling plate 10, but also pick up the cards behind it and return them to the shuffling plate 10. Referring to Figures 6(a) to 6(d), the card 90c is located between the shuffling plate 10 and the card delivery channel 20, and is not completely delivered into the card delivery channel 20. This card 90c can easily block other cards behind it, causing blockage at the entrance of the card delivery channel 20. By rotating the card-picking block 41 in this embodiment, the card 90c can be picked up from the card delivery channel 20.

[0043] In some embodiments, the card picking component 40 further includes a connecting block 42, which is rotatable and rotates in the opposite direction to the rotation direction of the shuffling disk 10. One or more card picking blocks 41 are arranged on the connecting block 42 along the rotation direction.

[0044] In this embodiment, the rotation of the card-picking block 41 follows the rotation of the connecting block 42. The connecting block 42 is driven to rotate by the power mechanism, which in turn drives the card-picking block 41 to rotate. By setting multiple card-picking blocks 41 on the connecting block 42, the card body 90a in the first state on its side can be quickly picked back to the shuffling plate 10.

[0045] like Figure 4 As shown in Figure 6(d), four card picking blocks 41 are arranged circumferentially on the outer peripheral surface of the connecting block 42.

[0046] In some embodiments, an auxiliary block 43 is provided between each pair of adjacent card blocks 41. The outer surface of the auxiliary block 43 is curved, and the shortest distance between the curved surface of the auxiliary block 43 and the side wall 21 of the channel is greater than the length of the card body 90.

[0047] The auxiliary blocks 43 are not placed between each pair of adjacent pick cards 41, but are arranged at intervals. For example, when there are four pick cards 41, there are two symmetrical auxiliary blocks 43. The auxiliary blocks 43 are recessed between two adjacent pick cards 41. When card body 90a or card body 90c is located between two adjacent pick cards 41, it can be quickly moved back to the shuffling plate under the guidance of the outer side of the auxiliary block 43.

[0048] Preferably, when there are N cards to choose from in block 41 and N is an even number greater than 2, then the auxiliary block 43 is N / 2.

[0049] Preferably, the auxiliary block 43 and the connecting block 42 are integrally formed.

[0050] In some embodiments, the side of the connecting block 42 away from the auxiliary block 43 is an arc-shaped surface. This allows for a certain guiding effect between two adjacent card picking blocks 41 that do not have an auxiliary block 43.

[0051] In some embodiments, the pick block 41 is an elastic block made of an elastic material.

[0052] In some embodiments, the pick block 41 is a polyurethane block or rubber block made of polyurethane or rubber material.

[0053] In some embodiments, the card picker 40 is connected to the power mechanism of the shuffling disc 10 via a card picker transmission mechanism. In this case, the card picker 40 and the shuffling disc 10 share the same power mechanism.

[0054] Specifically, the power mechanism can be connected to the card picking block 41 or the connecting block 42 through the card picking transmission mechanism.

[0055] The power mechanism can be a common power mechanism used in the existing technology for driving the shuffling plate 10 of the card sorting machine, such as a servo motor.

[0056] The card-picking transmission mechanism can use any existing transmission mechanism. Alternatively, the following design can be adopted: Reference Figure 2 and Figure 3A ring of face gears 441 is arranged on the bottom surface of the shuffling disc 10. A first gear 442 meshes with the face gear 441. A first connecting shaft 443 is fixedly connected to the first gear 442 and the second gear 444. The axial direction of the first connecting shaft 443 is the radial direction of the shuffling disc 10. The first connecting shaft 443 can be fixed to the fixing component of the card sorting machine via bearings. The second gear 444 meshes with the bevel gear 445, and the third gear 446 meshes with the bevel gear 445. A second connecting shaft 447 is fixedly connected to the third gear 446 and the fourth gear 448. The axial direction of the second connecting shaft 447 is vertical. Similarly, the second connecting shaft 447 can be fixed to the fixing component of the card sorting machine via bearings. The fifth gear 449 can directly mesh with or connect to the fourth gear 448 via a synchronous belt. The fifth gear 449 is fixedly connected to the card picking block 41 or the connecting block 42 via the third connecting shaft 440.

[0057] In some embodiments, the card picker 40 is connected to a separate power mechanism. In this case, the card picker 40 and the shuffling disc 10 are each driven by their own independent power mechanism.

[0058] The power mechanism of component 40 can be a commonly used power mechanism in existing technology, such as a servo motor.

[0059] Specifically, the rotating end of the power mechanism is connected to the pick block 41 or the connecting block 42.

[0060] In some embodiments, the card delivery channel 20 has a circular structure and is arranged around the edge of the shuffling disk 10.

[0061] The card delivery channel 20 can be either a rotatable channel or a fixed channel. A pushing device can be installed on the card delivery channel 20 or on the shuffling plate 10 to push the cards on the card delivery channel 20 to the conveying mechanism 80 that is connected to the card delivery channel 20.

[0062] Reference Figure 1 and Figure 2 The card delivery channel 20 is integrally formed with the shuffling plate 10. The edge of the shuffling plate 10 serves as the card delivery channel 20. At this time, the card delivery channel 20 is a circular and rotatable channel. The conveying mechanism 80 is connected to the card delivery channel 20 on the outside of the shuffling plate 10. At this time, the card blocking component 30 and the card picking component 40 are both located above the shuffling plate 10.

[0063] In some embodiments, the card delivery channel 20 has an arc-shaped structure, and four card delivery channels 20 are respectively arranged around the edge of the shuffling plate 10.

[0064] At this time, there are four independent card delivery channels 20. These channels can be movable or fixed. A pushing device can be installed on the card delivery channel 20 or on the shuffling plate 10 to push the cards on the channel to the conveying mechanism 80.

[0065] In some embodiments, the card delivery channel 20 is a card delivery channel with a movable bottom surface, and a pusher block is provided on the bottom surface of the channel.

[0066] In some embodiments, the pusher is disposed on the bottom surface of the channel on the side away from the shuffle disk 10, and the top surface of the pusher is a sloping cross-section, the height of the cross-section to the bottom surface of the channel gradually decreasing along the direction close to the shuffle disk 10.

[0067] In some embodiments, the shuffling plate 10 is provided with a pusher that rotates with the shuffling plate 10. The distance between the pusher and the channel sidewall 21 is greater than the width of the card delivery channel 20 and less than the length of the card body 90.

[0068] The pusher bar that follows the rotation of the shuffling plate 10 can push the card body 90 located at the edge of the shuffling plate 10 to the card delivery channel 20, and push the card body 90 on the card delivery channel 20 to the conveying structure.

[0069] Specifically, multiple push bars can be set, and the multiple push bars are evenly arranged along the 10 circumferences of the shuffling plate.

[0070] In some embodiments, the top surface of the pusher is a sloping cross-section, and the height of the cross-section to the shuffling disk 10 gradually decreases along the rotation direction of the shuffling disk 10.

[0071] In some embodiments, the rear portion of the card delivery channel 20 is shared with the edge portion of the shuffling disk 10.

[0072] At this time, the edge of the shuffling plate 10 serves as part of the card delivery channel 20, and the cards are delivered to the edge of the shuffling plate 10, which means they are delivered to the rear of the card delivery channel 20. At this time, the card blocking component 30 and the card picking component 40 are preferably located in the shared part of the card delivery channel 20 and the shuffling plate 10.

[0073] In some embodiments, the rear of the card delivery channel 20 is aligned with the edge of the shuffling disk 10.

[0074] At this time, the card delivery channel 20 is located outside the shuffling plate 10, and there is no shared part between the card delivery channel 20 and the shuffling plate 10. At this time, there is a connecting port on the side of the card blocking component 30 and the card picking component 40, which connects the card delivery channel 20 and the shuffling plate 10, so that the cards blocked by the card blocking component 30 or the cards picked out by the card picking component 40 can return to the shuffling plate 10.

[0075] In some embodiments, the card sorting device further includes a card-pushing bar 50, which extends from the center of the shuffling plate 10 to the edge of the shuffling plate 10.

[0076] Of course, the card-dispensing strip 50 will not extend into the card-feeding channel 20. When the edge of the shuffling plate 10 is shared with the rear of the card-feeding channel 20, the card-dispensing strip 50 will not extend into the shared portion.

[0077] Example 2: Refer to Figures 7 to 1 2(d) An embodiment of the present invention provides a card sorting machine card picking device, which is applied in a card sorting machine.

[0078] The card sorting and picking device of this embodiment differs from that of Embodiment 1 in that the structure of the card picking component is different, but the rest is the same as that of Embodiment 1, and will not be described again here.

[0079] The card picking component 60 in this embodiment includes a card picking block 61. The card picking block 61 can swing vertically in the inward and outward directions. The shortest distance between the card picking block 61 and the channel side wall 21 is greater than the width of the card body 90, and the longest distance between the card picking block 61 and the channel side wall 21 is less than the length of the card body 90. That is, the card picking block 61 swings back and forth in the inward and outward directions between the distance between it and the channel side wall 21 being greater than the width of the card body 90 and less than the length of the card body 90. When the card picking block 61 swings, it contacts the front side of the card body 90a in the first state and drives the card body 90a to move towards the shuffling plate 10.

[0080] Since the card picker 60 is located in front of the card blocker 30, when the cards 90 are sent from the shuffling plate 10 to the card delivery channel 20, they first pass through the card blocker 30, leaving cards in a horizontal state, namely card 90a in the first state and card 90b in the second state. Because the shortest distance between the card picker 61 and the channel side wall 21 is greater than the width of the card 90 and the longest distance is less than the length of the card 90, therefore, referring to... Figure 11 The card 90b in the second state will not be blocked by the card picker 61 and can pass smoothly through the card delivery channel 20. However, the card 90a in the first state will be blocked by the card picker 61. Since the card picker 61 is in a swinging state, referring to Figures 12(a) to 12(d), after the card picker 61 contacts the front side of the card 90a, its swinging motion gradually picks the card 90a from the outside to the inside until it is picked back to the shuffling plate 10. Therefore, under the action of the card picker 61, all the cards delivered through the card delivery channel 20 are the card 90b in the second state.

[0081] In some embodiments, the side of the card block 61 that contacts the card body 90 is an arc-shaped surface.

[0082] In some embodiments, refer to Figure 9 and Figure 10The card-picking component 60 also includes a cam 62 and a follower 63. The cam 62 is rotatable about the vertical direction. One end of the follower 63 is rotatably connected to the fixing part of the card sorting machine. The other end of the follower 63 is restricted in the slide groove 64 on the fixing part. The other end of the follower 63 is in high contact with the side of the cam 62. The follower 63 is connected to the card-picking block 61.

[0083] In this embodiment, the oscillation of the card picker 60 is provided by a cam mechanism consisting of a cam 62, a follower 63, and a fixing member.

[0084] The power source for cam 62 is similar to that in Embodiment 1. Cam 62 can be connected to the power mechanism of shuffling disc 10 via another card-picking transmission mechanism. In this case, card-picking component 60 and shuffling disc 10 share the same power mechanism. Cam 62 can also be connected to a separate power mechanism. In this case, card-picking component 60 and shuffling disc 10 are each driven by their own independent power mechanism.

[0085] When the card picking device 60 and the shuffling plate 10 share the same power mechanism, the power mechanism adopts a structure similar to that of Embodiment 1, with only some differences.

[0086] The similarities are as follows: a ring of face gears 441 is provided on the bottom surface of the shuffling disc 10. A first gear 442 meshes with the face gear 441. A first connecting shaft 443 is fixedly connected to the first gear 442 and the second gear 444. The axial direction of the first connecting shaft 443 is the radial direction of the shuffling disc 10. The first connecting shaft 443 can be fixed to the fixing component of the card sorting machine via bearings. The second gear 444 meshes with the bevel gear 445, and the third gear 446 meshes with the bevel gear 445. A second connecting shaft 447 is fixedly connected to the third gear 446. Similarly, the second connecting shaft 447 can be fixed to the fixing component of the card sorting machine via bearings.

[0087] The difference is that the second connecting shaft 447 is also fixedly connected to the cam 62.

[0088] In some embodiments, refer to Figures 8 to 10 A protective cover 65 is provided above the cam 62 to protect the cam 62 and the third gear 446.

[0089] Example 3: Reference Figures 13 to 1 7(d) An embodiment of the present invention provides a card sorting machine card picking device, which is applied in a card sorting machine.

[0090] The card sorting and card picking device in this embodiment differs from that in Embodiment 1 in the position and structure of the card picking component, but is otherwise the same as in Embodiment 1, and will not be described again here.

[0091] In this embodiment, the card picker 70 is located above the card delivery channel 20. The card picker 70 acts on the top surface of the card body 90a, giving the card body 90a a tendency to move towards the shuffling plate 10.

[0092] Specifically, the card picking component 70 includes a card picking block 71, which can rotate in the horizontal direction. The shortest distance between the card picking block 71 and the side wall 21 of the channel is greater than the width of the card body 90 and less than the length of the card body 90. The shortest distance between the card picking block 71 and the bottom surface of the channel is not greater than the height of the card body 90. When the card picking block 71 rotates, it contacts the top surface of the card body 90a in the first state below it and drives the card body 90 to move towards the shuffling plate 10.

[0093] Since the card picker 70 is located in front of the card blocker 30, when the cards 90 are sent from the shuffling plate 10 to the card delivery channel 20, they first pass through the card blocker 30, leaving cards in a horizontal state, namely card 90a in the first state and card 90b in the second state. Because the shortest distance between the card picker 71 and the channel side wall 21 is greater than the width of the card 90 but less than the length of the card 90, therefore, referring to... Figure 15 The card 90b in the second state will not be touched by the picker block 71 and can pass smoothly through the card delivery channel 20. Since the shortest distance between the picker block 71 and the bottom of the channel is no greater than the height of the card 90, the inner top surface of the card 90a in the first state will be touched by the picker block 71. Because the picker block 71 rotates horizontally, referring to Figures 16(a) to 16(b), after the picker block 71 touches the top surface of the card 90a, its rotation gradually picks the card 90a from the outside to the inside until it is picked back to the shuffling tray 10. Therefore, under the action of the picker block 71, all the cards delivered through the card delivery channel 20 are in the second state, namely, the card 90b.

[0094] Due to the aforementioned design of the card-picking block 71, it can not only pick up the card 90a located on its lower outer side and return it to the shuffling tray 10, but also pick up the cards below and on its lower inner side and return them to the shuffling tray 10. Referring to Figures 17(a) to 17(d), the card 90d whose outer side does not abut against the channel sidewall 21 will inevitably come into contact with the rotating card-picking block 71. As the card-picking block 71 rotates, the card 90d can be picked up from the outside to the inside until it is picked up back to the shuffling tray 10.

[0095] In some embodiments, the card-picking component 70 further includes a connecting block 72, which is rotatable about the horizontal direction, and one or more card-picking blocks 71 are arranged on the connecting block 72 along the rotation direction.

[0096] In this embodiment, the rotation of the card-picking block 71 follows the rotation of the connecting block 72. The connecting block 72 is driven to rotate by the power mechanism, which in turn drives the card-picking block 71 to rotate. By setting multiple card-picking blocks 71 on the connecting block 72, the card body 90a in the first state below it can be quickly picked back to the shuffling plate 10.

[0097] like Figures 15 to 1 As shown in 7(d), two card picking blocks 71 are arranged circumferentially on the outer side of the connecting block 72.

[0098] The power source for the connecting block 72 is similar to that in Embodiment 1. The connecting block 72 can be connected to the power mechanism of the shuffling disc 10 via another card picking transmission mechanism. In this case, the card picking component 70 and the shuffling disc 10 share the same power mechanism. Alternatively, the connecting block 72 can be connected to a separate power mechanism. In this case, the card picking component 70 and the shuffling disc 10 are each driven by their own independent power mechanism.

[0099] like Figures 15 to 1 As shown in 7(d), the connecting block 72 is connected to another independent power mechanism, which is a servo motor 73. The motor shaft of the servo motor 73 is horizontal, and the motor shaft of the servo motor 73 is connected to the card picking block 71 or the connecting block 72.

[0100] Example 4: This example provides a card sorting machine, which has the card sorting device provided in each of the examples 1, 2 or 3 of this invention.

[0101] In some embodiments, the card sorting machine is a mahjong machine, a poker machine, a domino machine, or a pull-a-middle card machine.

[0102] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
