[0003] Therefore, it is necessary to improve it. Summary of the invention

[0007] In addition, the lifting board in the existing patent document CN110652719A cannot determine whether the lifting board is lifted in place during the lifting process; if the lifting board is not lifted in place, cracks will appear on the tabletop; if the lifting board is not lowered in place, there is a step between the end of the lifting board and the housing, and the mahjong tiles will get stuck on the step. Therefore, in the present invention, further, the lifting device of the card sorting machine also includes: A sensor component capable of sensing the rise and fall of the card lifting plate of the card sorting machine is connected to the four-bar linkage.

[0008] Furthermore, the sensor assembly is connected to a driving member of the four-bar linkage.

[0010] Furthermore, the low-position sensor comprises: Low level sensor; A low-position induction sheet is arranged on the driving member and is inductively connected to the low-position sensor.

[0011] Furthermore, the high-position sensor comprises: High level sensor; A high-position induction sheet is arranged on the driving member and is inductively connected to the high-position sensor.

[0018] Furthermore, the card-raising device of the card sorting machine also includes: a plurality of connecting parts, which are respectively arranged at the four corners of the card sorting machine, and the other end of the card raising plate is arranged on the connecting parts.

[0021] Furthermore, the card sorting machine is a mahjong machine.

[0022] A card sorting machine is also proposed, which includes the card sorting machine card lifting device mentioned above.

[0023] The positive and progressive effects of the present invention are: 1) The card lifting device of the card sorting machine of the present invention adopts a four-bar linkage, which has a simple structure and occupies a small space. The linkage assembly can also replace the connecting rod, transmission gear, transmission shaft, connecting piece, rocker arm support and rocker arm in the prior art. The motor drives the four-bar linkage to directly drive the lifting plate to rise and fall, so the response speed is fast.

[0024] 2) The sensor component of the present invention includes a high-position sensor and a low-position sensor. The low-position sensor detects whether the card-lifting plate has been lowered into place, thereby reducing the risk of mahjong tiles being stuck. The high-position sensor detects whether the card-lifting plate has been raised into place, thereby reducing the probability of the table top of the card-sorting machine being uneven and improving the user experience.

Implementation

[0026] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0027] The fully automatic card sorting machine of the present invention is described by taking a mahjong machine as an example. Figures 1 to 8 The mahjong machine of the present invention includes four mahjong machine card-raising devices, which include a driving motor 10 and a four-bar linkage 20, and the four-bar linkage 20 is drivingly connected to the driving motor 10. More specifically, the driving motor has an output shaft, and the driving motor 10 is drivingly connected to the four-bar linkage 20 through the output shaft. The driving motor 10 drives the four-bar linkage 20 to move, thereby controlling the rise and fall of the card-raising plate 40 of the mahjong machine.

[0028] The drive motor 10 can be set inside the mahjong machine, and the setting position can be adaptively determined according to actual needs, preferably set at the outer wall of the shell 30; of course, in some special scenarios, the drive motor 10 can also be set outside the mahjong machine, such as the mahjong machine is in a maintenance state or the mahjong machine is a fixed mahjong machine; the size and output power of the drive motor 10 can be adaptively determined according to the size of the mahjong machine and actual needs.

[0029] The four-bar linkage 20 is specifically a crank rocker mechanism, and of course it can also be a double crank mechanism, a double rocker mechanism, a crank slider mechanism or a derivative structure of the four-bar linkage 20 that can play the same role. The output shaft of the drive motor 10 is drivingly connected to the rocker arm shown in the figure, and of course the output shaft can also be drivingly connected to a certain component of the four-bar linkage 20 according to actual needs. The four-bar linkage 20 is arranged inside the mahjong machine, and the specific setting position of the four-bar linkage 20 can be adaptively determined according to actual needs, and is preferably arranged at the outer side wall of the housing 30.

[0030] The four-bar linkage 20 includes a rocker arm 21 , a connecting rod 22 and a driving member 23 .

[0031] The rocker arm 21 is rod-shaped as a whole. The first end of the rocker arm 21 is drivingly connected to the driving motor 10 , and the second end of the rocker arm 21 is connected to the linkage rod 22 .

[0032] The connecting rod 22 is also rod-shaped as a whole. The first end of the connecting rod 22 is hinged to the second end of the rocker arm 21 , and the second end of the connecting rod 22 is connected to the connecting end of the driving member 23 .

[0033] The driving member 23 is a triangular plate, and the driving member 23 has a fixed end 231, a connecting end 232 and a driving end 233 at the three corners of the triangular plate. The driving end 233 is connected to the card raising plate 40, and is used to drive the card raising plate 40 of the mahjong machine to rise and fall. The connecting end 232 of the driving member 23 is hinged to the second end of the linkage rod 22, and the fixed end 231 of the driving member 23 is fixed to the outer wall of the housing 30. Of course, as mentioned above, the fixed end 231 of the driving member 23 can also be set somewhere inside the mahjong machine according to actual needs, and the shape of the driving member 23 can also be a circular plate or a regular or irregular shape that can meet actual needs.

[0034] A lifting rod 234 is fixed at the driving end 233. The lifting rod 234 can be inserted into the arc-shaped through hole 32 of the side wall of the housing 30 and can be moved up and down. One end of the card-raising plate 40 is abutted against the lifting rod 234. The lifting rod 234 is used to control the rise and fall of the card-raising plate 40 of the mahjong machine. The size of the lifting rod 234 and the angle at the driving end 233 can be adaptively determined according to actual needs. In a better example, the lifting rod 234 is arranged perpendicular to the plane of the driving member 23.

[0035] like Figures 6-8 As shown, the mahjong machine card upgrading device also includes a plurality of housings 30 , a card upgrading plate 40 and a connecting piece 50 .

[0036] The housing 30 is a U-shaped arc groove body, which serves as a track for the mahjong tiles to enter and exit. The U-shaped groove cavity of the housing 30 is a slideway for the mahjong tiles, and the housing 30 is provided with an arc-shaped through hole 32 at the side wall. The slideway is used for the card pushing device to push the mahjong tiles along the slideway to exit the cards. The slideway is built together with one end of the card lifting plate 40. The arc-shaped through hole 32 is used for the lifting rod 234 to pass through in an arc shape up and down. In a better example, when the lifting rod 234 is arranged perpendicular to the plane of the driving member 23, the arc-shaped through hole 32 is an arc-shaped slot hole matched with the lifting rod 234, that is, the arc-shaped through hole 32 is an arc ring with the fixed end 231 of the driving member 23 as the center and the distance from the fixed end 231 to the driving end 233 as the radius. The housing 30 also has a connecting plate 31, and the connecting plate 31 is coaxially fixed in the housing 30 of the mahjong machine through the fixed shaft of the fixed end 231 of the driving member 23.

[0037] The lifting board 40 is a long square board, and the bottom can be provided with a protruding side for easy installation. The lifting board 40 is set in the slideway, one end of the lifting board 40 is against the lifting rod 234, and the other end of the lifting board 40 is fixed on the connecting piece 50.

[0038] The connecting member 50 is in the shape of a quarter circle and is respectively arranged at the four corners of the mahjong machine. The other end of the card-raising plate 40 is arranged on the connecting member 50. One end of the connecting member 50 is fixed on the housing 30, and the connecting member 50 can also be integrally formed with the housing 30, and the card-raising plate 40 can be arranged on one end of the connecting member 50 in a hinged form.

[0039] like Figures 3 to 6 As shown, in one example, when the card lifting plate 40 needs to be lifted, the driving motor 10 drives the rocker arm 21 of the four-bar linkage 20 to rotate clockwise around the hinge point through the output shaft, thereby driving the linkage rod 22 to move, and the linkage rod 22 drives the driving member 23 to rotate correspondingly around the fixed end 232 through the connecting end 231. In this process, the driving end 233 of the driving member 23 rotates clockwise to lift the height, and the lifting rod 234 fixed to the driving end 233 is lifted in the arc-shaped through hole 32 matched therewith, and one end of the card lifting plate 40 resting on the lifting rod 234 is lifted until it reaches the same height as the other end of the card lifting plate 40, and at this time, the card lifting plate 40 is in a horizontal state as a whole, that is, the card lifting state is in place.

[0040] Similarly, in Figures 3 to 6 In another example shown, when it is necessary to lower the card raising plate 40, the driving motor 10 drives the rocker arm 21 of the four-bar linkage 20 to rotate counterclockwise around the hinge point through the output shaft, thereby driving the linkage rod 22 to move, and the linkage rod 22 drives the driving member 23 to rotate counterclockwise around the fixed end 232 through the connecting end 231. The driving end 233 of the driving member 23 rotates accordingly to reduce the height during this process, and the lifting rod 234 fixed to the driving end 233 is then reduced in height in the arc-shaped through hole 32 that cooperates with it, and one end of the card raising plate 40 that is against the lifting rod 234 is then lowered until it is against the lowest point of the slideway 20, at which time the card raising plate 40 is in an inclined state as a whole, that is, a card lowering state.

[0041] In order to detect whether the lifting board 40 lifts the mahjong tiles in place, the mahjong machine lifting device is also provided with a sensor assembly 60. The sensor assembly 60 is connected to the four-bar linkage 20, and more specifically, the sensor assembly 60 is connected to the driving member 23 of the four-bar linkage 20. The sensor assembly 60 includes a low-position sensor 61 for sensing whether the lifting board 40 of the mahjong machine has dropped to a low position and a high-position sensor 62 for sensing whether the lifting board 40 of the mahjong machine has risen to a high position. The low-position sensor 61 includes a low-position sensor 611 and a low-position sensor sheet 612, and the high-position sensor 62 includes a high-position sensor 621 and a high-position sensor sheet 622. Of course, if there are other detection requirements, additional sensor assemblies 60 can be set. For example, if it is necessary to monitor the entire process of lifting the mahjong tiles of the lifting board 40 to establish a finite element analysis, other sensor assemblies 60 can also be set at the corresponding position.

[0042] In one example, the low-position sensing sheet 612 is disposed on the driving member 23, the low-position sensor 611 is disposed on the connecting plate 31, and the sensing end for sensing on the low-position sensor 611 protrudes relative to the outer periphery of the connecting plate 31. Therefore, when the lifting plate descends, the driving motor 10 drives the rocker arm 21 of the four-bar linkage 20 to rotate around the hinge point through the output shaft, thereby driving the linkage rod 22 to move, and the linkage rod 22 drives the driving member 23 to rotate counterclockwise around the fixed end 232 through the connecting end 231. During this process, the driving end 233 of the driving member 23 rotates accordingly to lower its height, and the low-position sensing sheet 612 arranged on the driving member 23 also rotates to lower its height until the low-position sensing sheet 612 approaches and senses the sensing end of the low-position sensor 611 protruding outwardly arranged on the connecting plate 31. Since the setting positions of the low-position sensing sheet 612 and the sensing end of the low-position sensor are preset and correspond to the position of the card-lifting plate 40 in an inclined low position state, it is now indicated that the card-lifting plate has been lowered into place. Specifically, at this time, the low-position sensor 611 is electrically connected to the driving motor 10 through the PLC to complete the detection of whether the mahjong cards of the card-lifting plate 40 are in place.

[0043] Correspondingly, the high-position sensing sheet 622 is also arranged on the driving member 23, and the high-position sensor 621 is arranged on the outer wall of the shell 30. The high-position sensing sheet 622 protrudes relative to the outer periphery of the connecting plate 31. Therefore, when the lifting plate 40 rises, the driving motor 10 drives the rocker arm 21 of the four-bar mechanism 20 to rotate around the hinge point through the output shaft, thereby driving the connecting rod 22 to move, and the connecting rod 22 drives the driving member 23 to rotate clockwise around the fixed end 232 through the connecting end 231. During this process, the driving end 233 of the driving member 23 rotates accordingly to increase the height, and the high-position sensing piece 612 arranged on the driving member 23 also rotates to increase the height until the high-position sensing piece 622 approaches and senses the sensing end of the high-position sensor 621. Since the setting positions of the high-position sensing piece 622 and the sensing end of the high-position sensor 621 are preset and correspond to the position of the card-lifting plate 40 in a horizontal high position, it is now indicated that the card-lifting plate has been lifted into place. Specifically, the high-position sensor 621 is electrically connected to the driving motor 10 through the PLC to complete the detection of whether the raised mahjong cards of the card-lifting plate 40 are in place.

[0044] It is worth noting that the specific arrangement positions of the sensors and the sensing sheets of the sensing assembly 60 are not fixed and can be adaptively determined according to actual needs.
