Description

Technical Field

[0001] This invention belongs to the field of card sorting machine manufacturing, specifically relating to a swing-type card sorting machine flipping mechanism and the card sorting machine itself. Background Technology

[0002] Poker is a popular form of entertainment today. A poker game involves shuffling, arranging, and dealing the cards. Arranging and dealing are crucial steps in the game. During the arranging process, cards can easily become mixed up, with front and back sides mixed up. Dealing requires distinguishing between front and back cards and flipping front cards face down before dealing them.

[0003] Patent document CN110193184B discloses a poker machine and its poker card sorting method, specifically a panel with card-dispensing holes and a card dealer installed in the center of the card receiving base, also below the panel. The card dealer has a flipping channel for detected face-up poker cards, which need to be flipped 180° forward and backward through this channel. During this process, because the end of the flipping channel has a certain convex curvature, the passing poker cards are bent under the action of the flipping rollers, resulting in a complex structure and easy wear and tear on the poker cards. Summary of the Invention

[0021] Preferably, the receiving end of the receiving plate has a longitudinally inclined surface and a horizontal surface extending from the longitudinally inclined surface in an arc, the horizontal surface being spaced apart from the upper surface of the receiving plate by the thickness of a single card.

[0022] Preferably, the receiving plate also has a strip-shaped hole at the receiving stop end to facilitate the flipping space for the side where the card is stuck, and the strip-shaped hole is formed below the longitudinal inclined surface.

[0023] Preferably, the card-flipping mechanism of the swing-type card sorting machine further includes:

[0024] The rack and pinion lifting drive unit has one end connected to the drive rack and the other end connected to the drive mechanism.

[0025] Preferably,

[0038] Preferably, the drive mechanism is a motor.

[0039] Another object of the present invention is to provide a card sorting machine, the card sorting machine comprising: the swing-type card sorting machine flipping mechanism described in the present invention.

[0040] Preferably, the card sorting machine is a poker machine, mahjong machine, or dominoes machine.

[0041] The positive and progressive effects of this invention are as follows:

[0042] 1) This invention designs several fixed, circumferentially spaced card-flipping mechanisms and a circumferentially movable drive mechanism located on one side of these mechanisms. The drive mechanism can move circumferentially to any card-flipping mechanism and dock with it to drive the mechanism. This invention uses a single drive mechanism to rotate and drive multiple card-flipping mechanisms, reducing drive costs and simplifying the overall drive structure. Furthermore, this invention achieves precise engagement of the machine shaft into the machine shaft docking groove of the card-flipping mechanism by designing and controlling the shaft positioning component and the shaft docking groove at an initial preset height.

[0043] 2) The card-flipping mechanism of the present invention is designed as a swing-type card sorting machine. The card-flipping mechanism is driven by the rotation of the upper end of the swing arm of the card-flipping mechanism to flip the card receiving plate fixed at the lower end of the swing arm. This causes the face-up playing cards on the card receiving plate to be flipped at the same time. The card-flipping structure is simple and there is less contact with the playing cards during the card-flipping process, which greatly reduces the wear and tear on the playing cards.

[0044] 3) The present invention also achieves precise docking between the drive mechanism and the flipping mechanism during rotation by using a shaft positioning component to control the shaft of the drive mechanism to be at an initial preset height and using a lifting and resetting component to control the shaft docking groove to be at the same initial preset height.

[0045] 4) The present invention also designs a flip-up receiving plate, which has a first side for the card to slide in, a second side for stopping the card from sliding out, and a third and fourth side respectively having side end limiting strips when the card slides in. On the one hand, it facilitates the card to slide in and be stuck in, and on the other hand, it can better limit the sliding card to the receiving plate. Attached Figure Description

[0055] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through specific embodiments, and various details in this specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0056] It should be noted that in the description of this invention, the term "above" is used in a general sense and does not refer to the absolute top or upper surface. It can refer to various directions such as inside, outside, and below, and should not be construed as limiting the specific scope of protection of this invention.

[0057] like Figure 1 and Figure 2 As shown, the device for driving multiple card-flipping mechanisms with a single machine in the card sorting machine of the present invention includes several circumferentially spaced and fixed card-flipping mechanisms 1, a drive mechanism 2, a rotatable large disk 3, and a machine shaft positioning component 4. The drive mechanism 2 is circumferentially movable on one side of the several circumferentially arranged card-flipping mechanisms 1, and during the circumferential movement of the drive mechanism 2, it can engage with any card-flipping mechanism 1 to drive that engaged card-flipping mechanism 1. In this example, continuing as... Figure 1 As shown, both the drive mechanism 2 and the large plate 3 are located inside the card-flipping mechanisms 1, which are spaced circumferentially apart. The drive mechanism 2 is also fixedly mounted on the side wall inside the large plate 3. The shaft of the drive mechanism 2 passes through the side wall of the large plate 3, allowing it to move circumferentially as the large plate 3 rotates. In addition, the large plate 3 has a card-dispensing opening 31, which also rotates circumferentially to align with different card-flipping mechanisms 1. When the card-dispensing opening 31 of the large plate 3 aligns with one of the card-flipping mechanisms 1, the shaft of the drive mechanism 2, fixedly mounted on the large plate 3, can also align with that card-flipping mechanism 1 and drive it to flip the cards. After the cards are flipped by the card-flipping mechanism 1, they fall onto the card-lifting mechanism 5 below, which then lifts the cards to the tabletop of the poker machine.

[0058] Continue as Figure 3As shown, the card-flipping mechanism 1 is, for example, a swing-type card sorting machine card-flipping mechanism, including a card-receiving plate 11 that can flip back and forth between the card-receiving position and the temporary storage position, two spaced columns 12, two swing arms 13, a drive gear set 14, a drive rack 15, and a rack lifting drive component 16. The card-receiving plate 11 is fixedly connected to the lower end of the two swing arms 13, and the upper end of the two swing arms 13 is coaxially rotatably connected to the upper end of the corresponding column 12 with the upper end of the drive gear set 14. That is, by driving the drive gear set 14, the upper end of the coaxially connected swing arm 13 can be driven to rotate, and then the rotation of the upper end of the swing arm 13 can drive the lower end of the swing arm 13 to swing, and finally drive the card-receiving plate 11 fixedly connected to the lower end of the swing arm 13 to flip.

[0059] Continue as Figures 3-5 As shown, in this example, the motor, i.e., the drive mechanism 2, indirectly drives the drive gear set 14 through the rack and pinion lifting drive component 16 and the drive rack 15. Specifically, one end of the rack and pinion lifting drive component 16 is connected to the drive mechanism 2, and the other end is connected to the drive rack 15, which in turn meshes with the drive gear set 14. That is, the drive mechanism 2 first moves up and down by the drive rack and pinion lifting drive component 16, then the up and down moving rack and pinion lifting drive component 16 drives the drive rack 15, and finally the drive rack 15 drives the drive gear set 14 to rotate. Of course, the drive mechanism 2 can also directly drive the drive gear set 14 to rotate (not shown in the figure). Continuing as shown in the figure, in this example, the drive mechanism 2 is a drive motor, and the rack and pinion lifting drive component 16 includes two uprights 161, two lifting sleeves 162, a connecting rod 163, and a lifting and resetting component 164. Two uprights 161 are installed parallel to each other on the sides of the two columns 11. Two lifting sleeves 162 are slidably sleeved on the upper sections of the two uprights 161. The two ends of the connecting rod 163 are fixed to the two lifting sleeves 162. The lower end of the lifting reset component 164, i.e., the reset spring, is fixedly sleeved on the upright 161, and the upper end is fixedly connected to the lower end of the lifting sleeve 162, used to reset the lifting sleeves 162 and the connecting rod 163 to the initial preset height when they are raised or lowered by force. Continuing as... Figures 4-6As shown, the side wall of the connecting rod 163 has a shaft docking groove, also known as a horizontal pressing groove 1631. One end of the horizontal pressing groove 1631 is an inlet end 1631a that can be aligned with the shaft of the drive mechanism 2 at its initial preset height and slide in. The other end is an outlet end 1631b that the shaft of the drive mechanism 2 slides out at its initial preset height. The shaft of the drive mechanism 2 is provided with a bearing 21. When the drive mechanism 2 rotates circumferentially with the large disc 3 to dock with the current card flipping mechanism 1, the lifting sleeve 162 of the current card flipping mechanism 1 has been reset to its initial preset height by the spring force of the reset spring. The bearing 21 on the shaft of the drive mechanism 2 then slides in from the inlet end 1631a of the horizontal pressing groove 1631 of the current card flipping mechanism 1 and is inserted into the horizontal pressing groove 1631. After the drive mechanism 2 drives the current flipping mechanism 1 to flip, it returns to the initial preset height and can slide out from the outlet end 1631b of the horizontal pressing groove 1631. Then, the large plate 3 drives the drive mechanism 2 to rotate circumferentially and align with the inlet end 1631a of the horizontal pressing groove 1631 of the next flipping mechanism, so that it can slide in to drive the next flipping mechanism 1 to flip. Specifically, when the drive mechanism 2 drives the flipping mechanism 1 to flip, the drive mechanism 2 first applies vertical pressure to the connecting rod 163 through the bearing 21 inserted in the pressing groove 1631, so that the connecting rod 163 and the two lifting sleeves 162 connected to both ends of the connecting rod 163 move up and down. Continuing as shown in the figure, the drive gear set 14 is then driven by the drive rack 15, which is longitudinally installed on the outer surface of the lifting sleeve 162 and can move up and down with the lifting sleeve 162. The drive gear set 14 includes a driving gear 141 and a driven gear 142. The driven gear 142 is rotatably mounted on the upper end of the column 12 and is coaxially and fixedly connected to the upper end of the swing arm 13 on the upper end of the column 12. Simultaneously, the driven gear 142 meshes with the driving gear 141 and can be driven to rotate by the driving gear 141. The driving gear 141 meshes with a longitudinally mounted drive rack 15 and is driven to rotate by the drive rack 15. Thus, the drive mechanism 2 indirectly drives the drive gear set 14 to rotate via the rack-driven lifting member 16 and the drive rack 15. The rotating drive gear set 14 causes the swing arm 13 to swing around the column 12, and the swinging swing arm 13 further causes the receiving plate 11 fixed to the lower end of the swing arm 13 to rotate.

[0060] The flipping of the receiving plate 11 is achieved according to the following structure: Continuing as follows... Figure 7As shown, to ensure the flipping of the card receiving plate 11 driven by the swing arm 13, the card flipping mechanism 1 also has a flipping double gear set 17, which includes a base gear 171 and a traveling gear 172. The base gear 171 is fixedly mounted on the upper part of the column 12 with its teeth facing downwards; the traveling gear 172 is fixed to the lower end of the swing arm 13 with its teeth facing upwards, and the traveling gear 172 can reciprocate on the base gear 171. That is, the traveling gear 172 fixed to the lower end of the swing arm 13 reciprocates along the arc-shaped path of the lower end of the base gear 171, thereby causing the card receiving surface of the card receiving plate 11 to alternately face upwards and downwards, ensuring that the card receiving plate 11 flips and returns to its original position. Simultaneously, in order to better receive and flip the face-up playing cards from the card dispensing port 31, that is, when the card dispensing port 31 of the large plate 3 delivers a face-down playing card, the receiving plate 11 of the flipping mechanism 1 is in a temporary storage position and does not receive the face-down playing card. At this time, the traveling gear 172 that drives the receiving plate 11 to flip is located at the end of the base gear 171 away from the card dispensing port 31. When the card dispensing port 31 delivers a face-up playing card, the receiving plate 11 of the flipping mechanism 1 flips to the receiving position. That is, the traveling gear 172 that drives the receiving plate 11 to flip is moved along the arc-shaped path at the lower end of the base gear 171 from the end away from the card dispensing port 31 to the end of the base gear 171 closer to the card dispensing port 31.

[0061] Continue as Figure 4As shown, the positioning element 4 can be used to position the initial preset height of the drive motor shaft. Therefore, the positioning element can be considered as a shaft positioning element. The shaft positioning element includes one of the sensing plates 41 on the shaft of the drive mechanism 2 and a sensor 43 located outside the side wall of the large disk. By using the sensing connection between the sensing plate 41 and the sensor 43, the shaft of the drive mechanism 2 can be controlled to be at the initial preset height. At this time, the sensing plate 41 is the initial position sensing plate. In addition, in this example, the positioning element can also be used to position and control the receiving plate 11 to be in the temporary storage position and the receiving position. At this time, the positioning element 4 can be considered as a flip positioning element. The flip positioning element includes one sensing plate 41 (i.e., the temporary storage position sensing plate) on the shaft of the drive mechanism 2 to control the receiving plate 11 to be in the temporary storage position, another sensing plate 42 (i.e., the receiving position sensing plate) to control the receiving plate 11 to be in the receiving position, and a sensor 43 located outside the side wall of the large disk. The temporary storage position sensor and the card receiving position sensor are positioned relatively far apart on the shaft of the drive mechanism 2. When they are connected to the sensor 43, the card receiving plate 11 is in either the temporary storage position or the card receiving position. The sensor that controls the card receiving plate 11 to be in the temporary storage position and the sensor that controls the shaft of the drive mechanism 2 to be at the initial preset height can be the same sensor. When the shaft of the drive mechanism 2 rotates to the temporary storage position where the sensor plate 41 connects with the sensor 43, on the one hand, the bearing 21 on the shaft of the drive mechanism 2 is at the initial preset height, that is, the shaft can be aligned with the height of the sliding in and out horizontal pressing groove 1631. On the other hand, at this time, the traveling gear 172 at the lower end of the swing arm 13 of the flipping mechanism is engaged with the end of the base gear 171 away from the card outlet 31 of the large plate 3. At this time, the receiving plate 11 is relatively away from the card outlet 31 of the card dispensing mechanism of the large plate 3. The receiving plate 11's receiving stop end 112 is slightly tilted upward to make room above the receiving seat so that the playing cards sent by the card dispensing mechanism of the large plate 3 can fall onto the receiving seat of the card pulling and lifting mechanism. That is, the receiving plate 11 is in the temporary storage position (e.g., Figure 6 When the drive mechanism 2 drives the flip, the card receiving plate 42 senses the sensor 43, and the traveling gear 172 at the lower end of the swing arm 13 of the flipping mechanism meshes and moves to the end of the base gear 171 near the card outlet 31. At this time, the card receiving plate 11 is driven to flip once, that is, the card receiving plate 11 is driven to the card receiving position (e.g. Figure 5 At this point, the receiving plate 11 can receive the face-up playing cards sent from the card outlet 31 of the large plate 3. Finally, the drive mechanism 2 is driven in reverse again until the temporary storage sensor 41 senses the sensor 43 again. At this time, the receiving plate 11 is also driven back to the initial temporary storage position by the return stroke of the flip double gear set 17. At the same time, this flip also causes the received face-up playing cards to flip in the air to face-down playing cards, and the shaft of the drive mechanism 2 also returns to the initial preset height.

[0062] Continue as Figure 8A and Figure 8BAs shown, the card receiving plate 11 has a first side, a second side, a third side, and a fourth side, wherein the first side and the second side are arranged opposite each other, the third side and the fourth side are arranged opposite each other, and the third side and the fourth side are located between the first side and the second side. The first side is an inlet end 111 for the cards to slide in. A flipping shaft 117 is provided at both ends of the first side of the card receiving plate 11. The second side is a card receiving stop end 112 that stops the cards from sliding out, and the second side also forms a flipping circumference relative to the flipping shaft 117 of the first side. That is, the second side can rotate and flip around the flipping shaft 117 of the first side. In addition, the card receiving stop end 112 of the card receiving plate 11 has a longitudinally inclined surface 113, which forms an acute angle with the upper surface of the card receiving plate 11 to facilitate hooking and securing playing cards. A horizontal plane extends inward from the longitudinal inclined surface 113, forming a gap with the upper surface of the receiving plate 113 for the card to be inserted. This gap is the thickness of a single playing card, allowing a single playing card to be inserted. In addition, a strip-shaped hole 114 is provided below the longitudinal inclined surface 113 at the receiving end 112 to provide space for the playing card to be inserted. The strip-shaped hole 114 is formed below the longitudinal inclined surface 113, meaning that during the flipping of the receiving plate 11, the playing card hooked by the longitudinal inclined surface 113 provides flipping space for the side where the playing card is inserted. As shown in the figure, the card receiving plate 11's card inlet opening 111 also has an inclined side 115 that assists the card body in sliding into the upper surface of the card receiving plate 11, making it easier for the card body to slide into the card receiving plate 11. The third and fourth sides of the card receiving plate 11 also have side end limiting strips 116 when the card body slides in, which, together with the longitudinal inclined surface 113 at the card receiving stop end 112 on the second side, can better limit the card body that slides into the card receiving plate 11 within the upper surface of the card receiving plate 11.
