Description

Technical Field

[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 based on their card-flipping methods: 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 on it move towards the edge under the influence of rotation and centrifugal force. They are then transported through the card feeding channel between the shuffling disc and the conveying mechanism to the conveying mechanism, which then sends them to subsequent processes until a lifting mechanism pushes them out of the machine for user use.

[0004] In the non-magnetic method, once the required number of cards is reached on one side of the card sorting machine, the excess cards on the conveying mechanism cannot be discharged. Summary of the Invention

[0030] Referring to Figures 1(a) to 3(b), this embodiment of the invention provides a card sorting machine channel switching device based on a rear-mounted left and right opening and closing door, which is used in a card sorting machine.

[0031] Typically, as shown in Figures 2(a) to 2(b), the shuffling tray 91 of the card sorting machine is surrounded by a conveying mechanism 93. The edge of the shuffling tray 91 is provided with a rotatable annular feeding channel 92. Except for the feeding port, the other parts between the shuffling tray 91 and the feeding channel 92 can be separated by the channel wall. Cards 90 are dropped from the shuffling tray 91 into the feeding channel 92 through the feeding port. The inlet end of the conveying mechanism 93 is located within the feeding channel 92. Alternatively, in some card sorting machine structures, the feeding channel 92 may be omitted, in which case the shuffling tray 91 is surrounded by a conveying mechanism 93, and the shuffling tray 91 and the conveying mechanism 93, except for the inlet end of the conveying mechanism 93, can be separated by a partition. The cards 90 that fall from the edge of the shuffling plate 91 fall into the feeding channel 92 or the conveying mechanism 93. After being conveyed by the conveying mechanism 93, the cards 90 are sent to the flipping mechanism 94 for flipping or to the next station for other actions.

[0032] In order to discharge excess cards 90 on the conveying mechanism 93, when this embodiment is applied to the card sorting machine, a card sorting machine channel switching device 10 of this embodiment is provided around the shuffling plate 91 of the card sorting machine, so that excess cards 90 on each conveying mechanism 93 can be easily returned to the shuffling plate 91.

[0033] The card sorting machine channel switching device 10 in this embodiment includes a card entry channel, a first card exit channel, a second card exit channel, and a card guide 12.

[0034] The card feeding channel is formed by the passage between the shuffling plate 91 and the conveying mechanism 93. For example, the shuffling plate 91 is connected to the conveying mechanism 93 via the feeding channel 92, or the shuffling plate 91 is directly connected to the inlet end of the conveying mechanism 93.

[0035] The first card-dispensing channel is formed by the passage between the conveying mechanism and the lifting mechanism. The cards are sequentially sent to multiple processes through the first card-dispensing channel to perform actions, such as the card-flipping mechanism 94 flipping the cards, until the lifting mechanism pushes the cards out.

[0036] The second card dispensing channel is formed by the passage between the conveyor mechanism and the shuffling tray. Excess cards are returned to the shuffling tray 91 through the second card dispensing channel.

[0037] A second card outlet 11 is provided between the conveying mechanism and the second card dispensing channel. The second card outlet 11 is located between the conveying mechanism 93 and the shuffling plate 91, and is connected to the conveying mechanism 93 and the shuffling plate 91 to form the second card dispensing channel. That is, the card body 90 can be discharged to the shuffling plate 91 in sequence through the conveying mechanism 93 and the second card outlet 11.

[0038] The guide plate component 12 can rotate vertically, allowing it to switch between a first state and a second state.

[0039] In the first state, referring to Figures 1(a) and 1(b), the guide card 12 is located above the left side of the conveying mechanism 93. At this time, the guide card 12 does not block the conveying path of the conveying mechanism 93. The card inlet channel is connected to the first card outlet channel. The card body 90 can be directly sent to the card flipping mechanism 94 through the conveying mechanism 93 for card flipping or to the next work station for other actions.

[0040] In the second state, referring to Figures 1(c) and 1(d), the guide 12 spans above the conveying mechanism 93 in the width direction. The distance between the guide 12 and the conveying mechanism 93 is less than the height of the card, so that the guide 12 can guide the card to the second card dispensing channel. At this time, the guide 12 blocks the inlet and outlet conveying paths of the conveying mechanism 93, and the card 90 cannot pass through the conveying mechanism 93. The card inlet channel and the first card dispensing channel are separated, and the card inlet channel is switched to be connected to the second card dispensing channel. The card 90 can be discharged to the shuffling tray 91 in sequence through part of the conveying mechanism 93 at the rear end of the guide 12 and the second card dispensing port 11.

[0041] Taking a single conveying mechanism 93 as an example, its conveying direction is from the front end to the back end.

[0042] In some embodiments, the card sorting machine channel switching device 10 of this embodiment further includes a counter, which is disposed at least at one of the card inlet channel, the first card outlet channel and the conveying mechanism. The counter is configured to count the cards that pass through and, after satisfying a preset count value, give a drive signal for driving the card guide to move left and right.

[0043] In this embodiment, the counter can employ existing technology. The counter counts the passing cards to determine if the number of cards on one side of the card sorting machine is sufficient for subsequent card flipping or sorting. At this point, the remaining cards flowing in from that side need to be discharged. The discharge of the cards is achieved through the action of the card guide.

[0044] In actual implementation, the signal output terminal of the counter is connected to the existing controller of the card sorting machine. This controller is connected to the drive terminal for the left and right movement of the card guide component. The existing controller enables signal reception and control of the card guide component.

[0045] In some embodiments, the card guide 12 has a guide surface for guiding the card body from the conveying mechanism 93 to the second card dispensing channel, the guide surface being a planar, arc-shaped, or arc-like structure.

[0046] This embodiment allows the guide surface to be a non-strictly curved surface or a plane. The guide surface can be a semi-curved or curved structure. The guide surface only needs to be able to guide the card body 90 from the conveying mechanism 93 to the second card outlet 11.

[0047] In some embodiments, the front end of the guide plate 12 is hinged to a partition plate, which separates the conveying mechanism and the shuffling tray. The rear end of the guide plate 12 is a free end that can swing left and right about vertically.

[0048] When the card sorting machine is equipped with a feeding channel 92, the channel wall of the feeding channel 92 serves as the partition, and the front end of the card guide 12 is hinged to the left side of the feeding channel 92 as the connecting end.

[0049] Of course, the connecting end of the guide plate 12 can also be hinged to other fixing parts of the card sorting machine; this embodiment is not limited to its hinge position.

[0050] In some embodiments, the inlet end of the conveying mechanism 93 is disposed in the conveying channel 92, and the second outlet 11 is connected to the conveying channel 92.

[0051] In this embodiment, a rotatable annular feeding channel 92 is provided on the edge of the shuffling disc 91 of the card sorting machine. The feeding channel 92 is arranged around the edge of the shuffling disc 91, and its rotation direction is usually the same as that of the shuffling disc 91. Its rotation speed may be the same as or different from that of the shuffling disc 91.

[0052] In this embodiment, after the above design, the cards 90 fall from the edge of the shuffling tray 91 into the feeding channel 92, and are then conveyed to the conveying mechanism 93. The conveying mechanism 93 sequentially sends each card 90 to the flipping mechanism 94 for flipping or to the next station for other actions. When the conveying mechanism 93 is full, it sequentially sends each card 90 remaining on it to the second outlet 11. Since the second outlet 11 is connected to the feeding channel 92, as shown in Figures 2(a) and 2(b), the sent-out cards 90 flow into the feeding channel 92, and the annular feeding channel 92 conveys the cards 90 to the next conveying mechanism. In this way, the cards 90 can be quickly distributed by each conveying mechanism, and the cards 90 will not remain in the shuffling tray 91 for a long time.

[0053] In some embodiments, the guide plate 12 is connected to the connector 14, the front end of which is hinged to a partition plate to separate the conveying mechanism and the shuffling tray. The rear end of the guide plate 12 is rotatable left and right about vertically.

[0054] When the card sorting machine is equipped with a feeding channel 92, the channel wall of the feeding channel 92 serves as the partition, and the front end of the connector 14 is hinged to the right side channel wall of the feeding channel 92 as the connecting end.

[0055] Of course, the front end of the connector 14 can also be hinged to other fixing parts of the card sorting machine; this embodiment is not limited to its hinge position.

[0056] In some embodiments, the front end of the guide plate 12 is an outwardly expanding structure 12a, so that the front end of the guide plate 12 has a better guiding effect.

[0057] In some embodiments, the card sorting machine channel switching device 10 of this embodiment further includes a driving mechanism 13, which drives the card guide 12 to rotate vertically.

[0058] When the drive mechanism 13 is connected to the guide plate component 12, part of the structure of the drive mechanism 13 can pass through the second card outlet 11 to connect with the guide plate component 12, or a clearance opening can be opened on the right side wall of the delivery channel 92, and part of the structure of the drive mechanism 13 can pass through the clearance opening to connect with the guide plate component 12.

[0059] The drive mechanism 13 can be any device in the prior art capable of driving the guide plate 12 to rotate vertically. The drive mechanism 13 preferably adopts a crank-connecting rod mechanism, which drives the guide plate 12 to rotate vertically.

[0060] In some embodiments, the crank-connecting rod mechanism includes a drive motor 131, a crank 132, and a connecting rod assembly 133.

[0061] The motor shaft of the drive motor 131 is vertical. One end of the crank 132 is connected to the motor shaft of the drive motor 131. The connecting rod assembly 133 consists of two connecting rods. One end of the connecting rod assembly 133 is hinged to the other end of the crank 132, and the other end of the connecting rod assembly 133 is hinged to the guide plate 12.

[0062] The other end of the linkage assembly 133 is preferably hinged via a connecting plate integrally connected to the guide plate 12. This connecting plate is preferably located near the rear end of the guide plate 12.

[0063] In some embodiments, one end of the connecting rod 1331 near the guide plate member 12 in the connecting rod assembly 133 is connected to an adjacent connecting rod via a fisheye bearing 1332, and the other end is connected to the guide plate member 12 via another fisheye bearing 1332.

[0064] In some embodiments, the card sorting machine channel switching device of this embodiment further includes a card blocking component 15. The card blocking component 15 is movable so that it can switch between a first state and a second state. In the first state, the card blocking component 15 is located at the second card outlet 11 and is used to block the second card outlet 11. In the second state, the card blocking component 15 opens the second card outlet 11.

[0065] In this embodiment, the barrier component 15 can be driven to move by an independent drive source. Alternatively, the barrier component 15 can be driven by the same drive mechanism as the guide component 12. In this case, the barrier component is directly connected to the drive mechanism or through one or more connecting plates / components, for example, hinged to the other end of the linkage assembly 133.

[0066] In some embodiments, the card sorting machine channel switching device of this embodiment further includes a card blocking component 15. The card blocking component 15 is generally parallel to the card guide component 12 and is disposed on the connector 14. In the first state, the card blocking component 15 is located on the right side of the conveying mechanism 93 and on the left side of the second card outlet 11. The card blocking component 15 is used to block the second card outlet 11. In the second state, the card blocking component 15 opens the second card outlet 11.

[0067] Preferably, the guide plate component 12, the connector 14, and the barrier plate component 15 form an inverted U-shaped structure.

[0068] In this embodiment, the barrier component 15 is mounted on the connector 14, so it shares the same drive mechanism with the guide component 12.

[0069] In some embodiments, the front end of the barrier 15 is a connecting end hinged to the fixing member, and the rear end of the barrier 15 is a free end that can swing left and right around the vertical direction.

[0070] In some embodiments, the conveying mechanism 93 is a straight conveying mechanism with the inlet and outlet located on a straight path.

[0071] In some embodiments, when this embodiment is applied to a card sorting machine, the conveying mechanism 93 of the card sorting machine is preferably a belt conveyor mechanism, and the card body 90 is conveyed on the belt of the belt conveyor mechanism.

[0072] Of course, other conveying mechanisms can also be used for conveying mechanism 93. Example 2

[0073] Reference Figure 4 As shown in Figure 8(b), this embodiment provides a card sorting machine channel switching device based on a rear-mounted left and right opening and closing door, which is used in the card sorting machine.

[0074] The card sorting machine channel switching device in this embodiment differs from that in Embodiment 1 in the following ways, while the rest is the same as in Embodiment 1, and will not be described again here.

[0075] The crank-connecting rod mechanism in this embodiment adopts a different design than that in Embodiment 1.

[0076] The crank-connecting rod mechanism 16 of this embodiment includes a drive motor 161, a crank 162, a slider 163, a first connecting rod 164, a second connecting rod 165, a guide groove 166, and a sliding part 167.

[0077] The motor shaft of the drive motor 161 is vertical. One end of the crank 162 is connected to the motor shaft of the drive motor 161. The slider 163 can slide on the fixed member in the front-back direction. The slider 163 has a guide groove 166, the length direction of which is horizontal. Preferably, the length direction of the guide groove 166 intersects the front-back direction. One end of the first connecting rod 164 is hinged to the other end of the crank 162, and the other end of the first connecting rod 164 is hinged to the slider 163. One end of the second connecting rod 165 is hinged to the guide plate member 12, and the other end of the second connecting rod 165 is hinged to the stop plate member 15. The second connecting rod 165 has a sliding part 167, which slides on the guide groove 166.

[0078] Referring to Figures 5(a), 6(a), and 8(a), in the first state, the sliding part 167 is located at the rear end of the guide groove 166. At this time, the guide plate 12 is located on the left side of the conveying mechanism 93, and the blocking plate 15 is located on the right side of the conveying mechanism 93, blocking the second card outlet 11. As the crank-connecting rod mechanism is driven, referring to Figures 5(b), 6(b), and 8(b), as the sliding part 167 slides forward on the guide groove 166, the guide plate 12 and the blocking plate 15 switch from the first state to the second state. In the second state, the sliding part 167 is located at the front end of the guide groove 166. At this time, the guide plate 12 spans above the conveying mechanism 93, and the blocking plate 15 moves away from the second card outlet 11, opening the second card outlet 11 to form a passage with the second card outlet channel.
