Also, as disclosed in the chinese utility model with publication number CN211215377U, a tile pushing and lifting device for an automatic mahjong machine is disclosed, which comprises a frame, a U-shaped tile storage track and a tile lifting driving mechanism for driving the U-shaped tile storage track to lift are arranged on the frame, a tile storage channel and a tile discharging side at the side of the tile storage channel are formed on the U-shaped tile storage track; and a card pushing component which is synchronously lifted with the U-shaped card storage rail is arranged on the U-shaped card storage rail in a sliding way on one side opposite to the card outlet side, and a card pushing driving mechanism which is used for driving the card pushing component to horizontally displace towards the card outlet side to push the cards is arranged on the rack.
The existing mahjong machine tile pushing device has the following defects: (1) the radial position of the mahjong storage plate is always kept unchanged, so that the mahjong storage plate is not beneficial to retracting into the periphery of the mahjong machine for packing, and the mahjong lifting plate is difficult to be arranged closer to the center of the mahjong shuffling barrel; (2) the mahjong tiles on the storage board can be horizontally pushed onto the lifting board or the tabletop of the mahjong machine only by relying on the independently-translatable pushing board.
Disclosure of Invention
The invention aims to provide a tile pushing device of a mahjong machine, which has novel tile pushing mode and high tile pushing efficiency and provides convenience for the retraction of the periphery of the mahjong machine.
In order to achieve the purpose, the technical scheme of the invention is as follows:
a mahjong machine tile pushing device comprises a tile storage plate for storing mahjong tiles, wherein the tile storage plate comprises a tile storage platform, one length direction side of the tile storage platform is provided with a tile storage guardrail, and the other length direction side of the tile storage platform is a tile discharging side;
the mahjong storage plate is movably carried on the mahjong pushing seat and is driven by the mahjong loading driving mechanism to move along a supporting surface formed by the mahjong pushing seat, and the moving track of the mahjong storage plate extends to the position below the plane of the mahjong lifting plate so as to transfer mahjong to the mahjong lifting plate.
The mahjong storage plate is provided with the mahjong storage platform and the mahjong storage guardrail, the mahjong storage plate is movably arranged on the mahjong pushing seat, the mahjong loading driving mechanism drives the mahjong storage plate to move towards the direction of the mahjong lifting plate when the mahjong is pushed, and the moving track of the mahjong storage plate extends to the position below the plane of the mahjong lifting plate, so that the mahjong tiles on the mahjong storage plate can be shoveled by the mahjong lifting plate which keeps the position unchanged when the mahjong storage plate moves to the position below the mahjong lifting plate under the pushing of the mahjong storage guardrail, and the mahjong tiles can be rapidly transferred from the mahjong storage plate to the mahjong lifting plate. The tile pushing structure not only omits a tile pushing plate in the traditional mahjong machine, but also can arrange the tile lifting plate to be closer to the center of the shuffling barrel because the tile storage plate moves towards the tile lifting plate, thereby being convenient for a player to grab tiles.
Meanwhile, the mahjong storage plates are generally arranged on the periphery of four sides of the mahjong machine, and compared with the traditional mahjong storage plates with unchanged positions, the mahjong storage plates can move, so that the mahjong storage plates can be pushed towards the direction of the shuffling barrel when the mahjong machine is packed or stored, the possibility of retracting the periphery of the mahjong machine is provided, and the mahjong machine can be packed by adopting a smaller packing box.
In order to facilitate the lifting plate to scoop up mahjong tiles on the tile storage plate, in the tile pushing device of the mahjong machine, the moving track of the tile storage plate and the plane where the tile lifting plate is located form an included angle which is between 90 degrees and 180 degrees;
or the moving track of the card storage plate is parallel to the plane where the card lifting plate is located.
In the invention, the card lifting plate can be obliquely arranged, when the card is lifted, the card lifting plate adopts a slope card lifting mode, at the moment, the card storage plate can be horizontally arranged or obliquely arranged, and the card lifting plate is inclined towards the direction of increasing the included angle between the card lifting plate and the card storage plate, namely, the card discharging side is obliquely downwards arranged towards the card storage guardrail side; the card lifting plate can also be horizontally arranged, so that when the cards are lifted, the cards are lifted vertically in a card lifting mode, and the card storage plate is also preferably horizontally arranged.
Preferably, in the above-mentioned mahjong machine tile pushing device, at least one side of the tile lifting plate close to the tile storage plate is in contact with the tile storage plate. When the moving track of the card storage plate forms an included angle with the plane where the card lifting plate is located, one side of the card lifting plate close to the card storage plate is preferably arranged to be in contact with the card storage plate; when the moving track of the mahjong storage plate is parallel to the plane of the mahjong lifting plate, the whole bottom surface of the mahjong lifting plate is preferably arranged to be in contact with the top surface of the mahjong storage plate, so that the height difference between the top surface of the mahjong storage plate and the top surface of the mahjong lifting plate can be shortened, and the mahjong is prevented from being influenced to be transferred.
In the mahjong machine tile pushing device, in the moving direction of the tile storage plate, the support surface of the tile pushing seat is narrower than the tile storage plate, one side of the tile storage plate at the tile pushing starting point, which is close to the tile lifting plate, is carried on the support surface, and the side of the tile storage plate, which is far away from the tile lifting plate, is suspended;
the card feeding driving mechanism is arranged on one side of the card pushing seat facing the card lifting plate.
Therefore, when the mahjong storage plate moves towards the mahjong lifting plate along the supporting surface, the space outside the mahjong pushing seat can be gradually vacated, so that the mahjong pushing seat is greatly retracted into the periphery of the mahjong machine, and the smaller packing box can be conveniently adopted for packing the mahjong machine.
In the above tile pushing device of the mahjong machine, the tile feeding driving mechanism comprises:
a mahjong loading motor;
a transmission cam linked with an output shaft of the mahjong loading motor;
the card pushing transmission component is arranged between the transmission cam and the card storage plate.
Preferably, in the tile pushing device of the mahjong machine, the tile pushing transmission assembly comprises an S-shaped tile pushing track arranged on the bottom surface of the tile storage plate, the S-shaped tile pushing track comprises a pushing section and a returning section which are arranged in central symmetry about a midpoint of the track, one end of the pushing section, which is far away from the midpoint of the track, is a pushing starting point, one end of the returning section, which is far away from the midpoint of the track, is a returning starting point, and the pushing section and the returning section are both arc-shaped and have central angles of arcs of 90 degrees;
the radial position of the transmission cam is provided with a tile pushing roller which is matched with the S-shaped tile pushing track in a rolling way, the tile pushing roller is provided with a tile pushing preparation position which rolls from the middle point of the track to the starting point of the pushing process along the pushing process section, a tile pushing position which rolls from the starting point of the pushing process to the middle point of the track so as to enable the tile storage plate to move towards the tile lifting plate, a return preparation position which rolls from the middle point of the track to the starting point of the return process along the return process section, and a return position which rolls from the starting point of the return process to the middle point of the track so as to enable the tile storage plate to return to the initial position.
Because the central angles of the push section and the return section are both 90 degrees, the card pushing roller goes through the turn of the card pushing preparation position, the card pushing position, the return preparation position and the return position every time the transmission cam rotates for one circle, and the card storage plate finishes one card pushing action.
Due to the slope and thickness of the card lifting plate and the possible height difference between the card storing plate and the card lifting plate, the mahjong can be blocked when being transferred from the card storing plate to the card lifting plate. In order to eliminate the block of pushing the mahjong tiles, in the mahjong machine tile pushing device, the tile pushing seat is further provided with a tile pushing component (55) which is used for upwards pushing up the mahjong tiles on the tile storage plate towards one end of the tile outlet side so as to prevent the mahjong tiles from being stuck at the lap joint of the tile storage plate and the tile lifting plate, and the tile storage platform is provided with a tile pushing port which is convenient for the tile pushing component to implement the tile pushing action.
After the mahjong tiles are upwards jacked towards one end of the tile lifting plate (namely the front end of the mahjong tiles and defined by the advancing direction of the mahjong tiles) by adopting the tile jacking assembly, an avoiding space is formed between the front end of the mahjong tiles and the tile storage plate, and when the mahjong tiles are transferred from the tile storage plate to the tile lifting plate, the tile lifting plate shovels the mahjong tiles due to the fact that the mahjong tiles are brought into the avoiding space, so that the mahjong tiles and the tile lifting plate can be prevented from being jacked tightly, and the blocking of pushing the mahjong tiles is effectively eliminated.
Preferably, in the above tile pushing device for a mahjong machine, the tile pushing assembly comprises:
the fixed end of the mahjong lifting rocker arm is hinged with the rack, and the free end of the mahjong lifting rocker arm swings around the fixed end of the mahjong lifting rocker arm;
the card pushing plate is movably arranged on the card pushing seat;
and one end of the pushing push rod is fixedly connected with the mahjong lifting rocker arm, and the other end of the pushing push rod is rotatably connected with the mahjong pushing plate so as to drive the mahjong pushing plate to lift.
One end of the card pushing rod is fixedly connected with the card lifting rocker arm, so that when the card lifting rocker arm swings, the other end of the card pushing rod also moves; because the push rod and the card-pushing plate are connected in a rotating way, when the card-pushing plate is pushed to move, the card-pushing plate can also ascend or descend relative to the card-pushing seat, when the card-pushing plate ascends, the mahjong cards are pushed, and when the card-pushing plate descends, the mahjong cards are not pushed.

The front end of the mahjong tiles stored on the tile storage plate is spaced from the tile lifting plate by a certain distance, so that the support of the tile pushing plate on the front end of the mahjong tiles needs to be continued for a period of time until the tile storage plate moves to the position where the front end of the mahjong tiles is overlapped on the tile lifting plate, and the support of the mahjong tiles can not be released by the tile pushing plate. Therefore, the width of the card-pushing opening needs to be set larger than the width of the card-pushing plate, so as to ensure that the card-pushing plate can keep pushing the mahjong cards while the card-storing plate moves.
In the mahjong machine tile pushing device, an accommodating groove for accommodating the tile pushing plate is formed in the top surface of the tile pushing seat, at least one through hole communicated with the accommodating groove is formed in the side surface of the tile pushing seat, and the tile pushing push rod is in transmission with the tile pushing plate from the through hole;
a limit part for limiting the card pushing height of the card pushing plate is arranged between the card pushing plate and the card pushing seat or between the card pushing plate and the card storing plate;
the mahjong tile pushing plate is characterized in that a plurality of reinforcing ribs are arranged on the inner edge of the opening of the tile pushing opening along the length direction of the tile pushing opening, notches matched with the reinforcing ribs are formed in the tile pushing plate, and the width of each reinforcing rib is smaller than that of a mahjong tile.
After the through opening communicated with the containing groove is formed in the card pushing seat, the card pushing push rod and the card pushing plate outside the card pushing seat can be conveniently driven, the contact area between the card pushing seat and the card pushing plate can be reduced, the friction force between the card pushing seat and the card pushing plate is reduced, and therefore the power required by the card pushing push rod to drive the card pushing plate to lift along the containing groove is saved.
The limit piece is arranged between the mahjong pushing plate and the mahjong pushing seat or between the mahjong pushing plate and the mahjong storing plate and can be used for limiting the mahjong pushing height of the mahjong pushing plate, so that the mahjong tiles are prevented from being twisted due to the excessive force of the mahjong pushing plate. Specifically, a limit step can be arranged on the top surface of the card pushing plate, and when the card pushing plate rises to enable the limit step to abut against the outer edge of the opening of the containing groove on the card pushing seat or enable the limit step to abut against the outer edge of the opening of the card pushing opening on the card storing plate, the card pushing plate reaches the maximum card pushing height.
Because the width of the card pushing port is larger, in order to ensure the strength of the card storage plate, the invention arranges the reinforcing ribs at the inner edge of the opening of the card pushing port, and arranges the gaps matched with the reinforcing ribs on the card pushing plate; in order to prevent the strengthening ribs from influencing the jacking of the mahjong tiles by the tile jacking plate, the width of the strengthening ribs is set to be not more than that of the mahjong tiles.
In the tile pushing device of the mahjong machine, the tile lifting rocker arm is driven by the tile feeding push rod to swing, one end of the tile feeding push rod is fixedly connected with the tile lifting rocker arm, the other end of the tile feeding push rod is provided with the tile feeding roller, and the tile feeding roller is in rolling fit with the tile feeding curved groove formed in the transmission cam to drive the tile lifting rocker arm to swing;
the mahjong loading curved surface groove comprises a mahjong pushing section, a first-stage mahjong pushing section and a second-stage mahjong pushing section which are sequentially connected, the mahjong loading roller is provided with a mahjong pushing position which rolls along the mahjong pushing section to enable a mahjong pushing push rod to lift the mahjong pushing plate, rolls along the first-stage mahjong pushing section to enable the mahjong storage plate to move towards the mahjong lifting plate to horizontally push mahjong parts to the first-stage mahjong pushing position on the mahjong lifting plate, and rolls along the second-stage mahjong pushing section to enable the mahjong pushing push rod to release the jacking of the mahjong pushing plate and enable the mahjong storage plate to completely horizontally push mahjong to the second-stage mahjong pushing position on the mahjong lifting plate;
the bottom surface of the card storage plate is provided with a guide piece penetrating through the card pushing seat;
the bottom surface of the card storage plate is provided with a row of concave areas arranged along the length direction of the card storage plate, each concave area is strip-shaped, and the length extension direction of each concave area is consistent with the moving direction of the card storage plate.
According to the invention, the transmission cam is provided with the mahjong tile feeding curved surface groove, and the mahjong tile feeding curved surface groove and the mahjong tile pushing roller are respectively positioned at two opposite sides of the transmission cam, so that the transmission cam can synchronously drive the mahjong tile storage plate to push the mahjong tiles and the mahjong tile pushing plate to push the mahjong tiles, and the power cost is saved.
According to the execution method of the card pushing and card ejecting actions, a card ejecting section, a first-stage card pushing section and a second-stage card pushing section are arranged in the upper card curved surface groove; in the initial tile pushing stage, the transmission cam rotates to enable the tile pushing section to reach the tile loading roller, the tile loading roller rolls along the tile pushing section to enable the tile lifting rocker arm to swing towards the direction of the shuffling barrel, and the tile pushing push rod drives the tile pushing plate to rise along the accommodating groove to push up the front end of the mahjong tile; at the moment, the card pushing roller also reaches the starting point of the pushing process; then, the transmission cam rotates to enable the first-stage tile pushing section to reach the tile loading roller, the tile loading roller rolls along the first-stage tile pushing section, the tile lifting rocker arm and the tile pushing push rod keep unchanged in position, the tile pushing plate keeps pushing the tiles, the tile pushing roller rolls from the pushing range starting point to the center of the track along the pushing range section, the tile storage plate moves towards the direction of the tile shuffling barrel until the front end of the mahjong tile is lapped on the tile lifting plate; and finally, the transmission cam rotates to enable the secondary tile pushing section to reach the tile feeding roller, the tile feeding roller rolls along the secondary tile pushing section to enable the tile lifting rocker arm to swing in the direction far away from the shuffling barrel, the tile pushing push rod swings downwards to release the jacking of the tile pushing plate, the tile pushing plate descends along the accommodating groove along the tile pushing push rod under the action of gravity to release the jacking of mahjong tiles, at the moment, the tile pushing roller continuously rolls towards the center of the track along the pushing section to enable the tile storage plate to continuously move in the shuffling barrel until all mahjong tiles are overlapped on the tile lifting plate, and tile pushing is completed.

After the depressed area 12e is arranged, the contact area between the card storage plate 12 and the card pushing seat 6 is greatly reduced, so that the moving resistance of the card storage plate 12 is reduced, and unnecessary abrasion between the card storage plate and the card pushing seat is also reduced.
The recessed area 12e may be only disposed on the bottom surface of the card storage platform 12a, or may extend from the bottom surface of the card storage platform 12a to the back surface of the card storage fence 12 b; therefore, the whole weight of the card storage plate 12 can be greatly reduced while the strength of the card storage guardrail 12b is ensured.
As shown in FIG. 1, in the present embodiment, the tile lifting plate 3 of the mahjong machine is located on the tile discharging side of the tile storage platform 12 a; the tile lifting plate 3 of the embodiment adopts a slope tile lifting mode, namely one length direction side of the tile lifting plate 3 is hinged with the frame or the panel of the mahjong machine, and the other length direction side can be lifted up and down under the driving of the tile lifting driving mechanism 5; after descending, the card lifting plate 3 is overlapped on the card outlet side of the card storage plate 12 in a slope shape.
Obviously, as the card lifting plate 3 is erected on the card storage plate 12 after descending, the moving track of the card storage plate 12 extends to the lower part of the plane where the card lifting plate 3 is located; due to the existence of the card storage guardrail 12b, the mahjong tiles on the card bearing platform 12a can be horizontally pushed onto the card lifting plate 3 along with the gradual movement of the card storage plate 12 to the card lifting plate 3.
In order to smoothly transfer the mahjong tiles from the tile storage plate 12 to the tile lifting plate 3, the present embodiment sets the angle between the tile lifting plate 3 and the tile storage plate 12 after being lowered to be between 90 ° and 180 ° (excluding 90 ° and 180 °), more preferably between 120 ° and 180 ° (including 120 ° and 180 °), and most preferably between 150 ° and 180 ° (including 150 ° and 180 °), and obviously, the larger the angle is, the smoother the transfer of the mahjong tiles is.
That is, in the present embodiment, the card storage plate 12 may be disposed horizontally or obliquely, and should be inclined toward a direction that increases an included angle between the card lifting plate 3 and the card storage plate 12, that is, inclined downward from the card outlet side to the card storage guardrail 12b side; accordingly, the supporting surface of the card shoe 6 also has the same inclination angle as the card storage plate 12.
As shown in fig. 1, the card-feeding driving mechanism 5 in this embodiment includes a card-feeding motor 51, a driving cam 52 is fixedly mounted on an output shaft of the card-feeding motor 51, the card-lifting plate 3 and the driving cam 52 are driven by a card-lifting driving assembly 53, and the card-storing plate 12 and the driving cam 52 are driven by a card-pushing driving assembly 54.
The card-raising transmission assembly 53 includes a card-raising base 531 fixedly mounted on the bottom surface of the card-raising plate 3, as shown in fig. 6, a card-raising curved groove 531a is formed on the side surface of the card-raising base 531; the fixed end of the tile lifting rocker arm 532 is hinged with the frame, the free end is provided with a tile lifting roller 533 which is matched with the tile lifting curved groove 531a in a rolling way, and the tile lifting roller 533 can roll along the tile lifting curved groove 531a to drive the tile lifting plate 3 to turn over; the rolling power of the card-lifting roller 533 comes from the swing of the card-lifting rocker arm 532, and the swing of the card-lifting rocker arm 532 is driven by the card-loading push rod 534.
In this embodiment, the way that the mahjong loading push rod 534 drives the mahjong lifting rocker arm 532 to swing is as follows: the card-feeding pushing rod 534 is fixedly connected with the card-lifting rocker arm 532 at one end and is provided with a card-feeding roller 535 at the other end, the card-feeding roller 535 is in rolling fit with a card-feeding curved groove 521 (shown in fig. 2) formed on the transmission cam 52, when the transmission cam 52 rotates, the card-feeding roller 535 rolls along the card-feeding curved groove 521 and pushes and pulls the card-feeding pushing rod 534, and therefore the card-feeding pushing rod 534 can drive the card-lifting rocker arm 532 to swing.
In order to ensure that the card lifting plate 3 is lifted stably, in the embodiment, two card lifting seats 531 and two card lifting rocker arms 532 are arranged at each card lifting plate 3, the two card lifting rocker arms 532 are linked through a linkage rod 536, and the card feeding push rod 534 is fixedly connected with the linkage rod 536.

The structure of the mahjong lifting rocker arm 532 can adjust the length of the extension arm 532b without changing the connection structure between the mahjong lifting rocker arm 532 and the linkage rod 536 so as to adapt to mahjong machines with different specifications.
As shown in fig. 6, the card raising curved groove 531a of the card raising base 531 has a positioning notch 531aa at a lower position and a groove bottom 531ab at a higher position, and a first limit corner 531ac is formed between the positioning notch 531aa and the card raising curved groove 531 a. When the tile lifting roller 533 is located in the positioning notch 531aa (as shown in fig. 8), the tile lifting plate 3 is kept flush with the mahjong machine panel 100, and due to the limitation of the first limiting corner 531ac, the tile lifting roller 533 can be kept in the positioning notch 531aa when not stressed, so as to ensure the stable position of the tile lifting plate 3; when the card-lifting rocker arm 532 swings, the card-lifting roller 533 can cross the first limit corner 531ac and roll along the card-lifting curved groove 531a, and at this time, the card-lifting plate 3 descends and is erected on the card-storing plate 12 (as shown in fig. 9) to wait for card pushing; after the mahjong tiles are completely pushed to the tile lifting plate 3 by the tile storage plate 12, the tile lifting plate 3 is lifted.
Accordingly, as shown in fig. 6, the curved card-playing groove 521 of the driving cam 52 includes a descending section 521a, a card-pushing section 521b and an ascending section 521c connected in sequence, when the driving cam 52 rotates to make the descending section 521a reach the card-playing roller 535, the card-playing roller 535 rolls along the descending section 521a, the card-lifting rocker arm 532 swings towards the shuffling barrel, the card-lifting roller 533 rolls from the positioning notch 531aa to the groove bottom 531ab along the curved card-lifting groove 531a, and the card-lifting plate 3 descends; when the driving cam 52 rotates to make the card sending section 521b reach the card loading roller 535, the card loading roller 535 rolls along the card sending section 521b, the card storage plate 12 moves towards the card lifting plate 3 under the driving of the card pushing driving component 54 to horizontally push the mahjong cards onto the card lifting plate 3; when the driving cam 52 rotates to make the upwarp section 521c reach the mahjong tile loading roller 535, the mahjong tile loading roller 535 rolls along the upwarp section 521c, the mahjong tile lifting rocker arm 532 swings back to the shuffling barrel, the mahjong tile lifting roller 533 rolls from the bottom of the groove to the positioning notch 531aa along the mahjong tile lifting curve groove 531a, and the mahjong tile lifting plate 3 is upwarped to be flush with the mahjong machine panel 100.
As shown in fig. 1 and 5, the card pushing transmission assembly 54 of the present embodiment includes an S-shaped card pushing track 541 disposed on the bottom surface of the card storage plate 12, the S-shaped card pushing track 541 includes a pushing section 541b and a returning section 541c disposed symmetrically with respect to the center of the track midpoint 541a, the pushing section 541b and the returning section 541c are both arc-shaped and have central angles of both arc-shaped being 90 °, wherein one end of the pushing section 541b away from the track midpoint 541a is a pushing starting point 541d, and one end of the returning section 541c away from the track midpoint 541a is a returning starting point 541 e; as shown in fig. 1 and 3, the radial position of the drive cam 52 is provided with a card-pushing roller 542 which is in rolling engagement with the S-shaped card-pushing track 541, and the card-pushing roller 542 and the card-holding groove 521 are respectively provided on both sides of the drive cam 52.
In this embodiment, the tile pushing roller 542 has four movement processes of a tile pushing preparation position (from the middle point of the track to the pushing start point), a tile pushing position (from the pushing start point to the middle point of the track), a return preparation position (from the middle point of the track to the return start point), and a return position (from the return start point to the middle point of the track); in accordance therewith, as shown in fig. 6, the upturned section 521c in the superscript curved slot 521 is also divided into a primary upturned section 521ca and a secondary upturned section 521 cb.
When the card-loading roller 535 rolls along the descending segment 521a, the card-pushing roller 542 rolls along the pushing segment 541b from the middle point 541a of the track to the starting point 541d of the pushing process to prepare for pushing cards; in this process, the rolling track of the card pushing roller 542 is exactly concentric with the rotating track of the driving cam 52, so that the card storage plate 12 is kept unchanged; when the card-loading roller 535 rolls along the card-pushing section 521b, the card-pushing roller 542 rolls from the starting point 541d to the middle point 541a of the track along the pushing section 541b, so that the card-storing plate 12 moves towards the card-lifting plate 3 to complete the card-pushing; when the tile feeding roller 535 rolls along the first-stage upwarping section 521ca, the tile lifting rocker arm 532 can only drive the tile lifting plate 3 to upwarp to expose the mahjong tiles on the mahjong machine panel 100 towards one side of the tile storage guardrail 12b, and the tile pushing roller 542 rolls from the track midpoint 541a to the return starting point 541e along the return section 541c to prepare for return; in the process, as the rolling track of the tile pushing roller 542 is exactly concentric with the rotating track of the transmission cam 52, the tile storage plate 12 also keeps the same position and is positioned at the tile pushing endpoint thereof so as to protect the mahjong tiles on the tile lifting plate 3; when the card-feeding roller 535 rolls along the secondary upwarping section 521cb, the card-lifting plate 3 continues to warp until it is flush with the mahjong machine panel 100, and the card-pushing roller 542 rolls along the return section 541c from the return starting point 541e to the track midpoint 541a to return the card-storing plate 12 to the initial position to wait for card storage.
Due to the slope and thickness of the card lifting plate 3 and the possible height difference between the card lifting plate 3 and the card storing plate 12, the top surface of the card lifting plate 3 and the top surface of the card storing plate 12 have more or less height difference, and the existence of the height difference can influence the smooth transfer of mahjong cards. In order to eliminate the influence, as shown in fig. 1, 4 and 8, in the embodiment, the card pushing base 6 is provided with a card pushing assembly 55 for pushing up the mahjong tiles toward one end of the card lifting plate 3 so as to prevent the mahjong tiles from being stuck at the overlapping position of the card storage plate 12 and the card lifting plate 3, the card storage plate 12 is provided with a card pushing port 12f for facilitating the card pushing assembly 55 to carry out a card pushing action, and the distance between the card pushing port 12f and the card lifting plate 3 should be less than the length of one mahjong tile. The card ejecting opening 12f is strip-shaped, and the length extending direction of the card ejecting opening is consistent with that of the card storage plate 12, so that when mahjong tiles are stored on the card storage plate 12, all the mahjong tiles can be exposed at the card ejecting opening 12f and ejected.
As shown in fig. 1, 4 and 7, an accommodation groove 61 is formed on the top surface of the card-pushing base 6, and a card-pushing plate 551 is movably installed in the accommodation groove 61; a plurality of through holes 62 communicated with the containing groove 61 are formed on the side surface of the card pushing seat 6; the top board 551 has a connecting lug 551c extending from one of the through holes 62 to the outside of the card pushing base 6, the top board 551 can be driven to slide upwards along the containing groove 61 by the top board pushing rod 553 which is rotatably connected with the connecting lug 551c, the top board 551 can extend out from the top board hole 12f to push the mahjong tile upwards towards one end of the card lifting board 3.
As shown in fig. 1, 4 and 7, in this embodiment, the top end of the top plate 551 has a top plate 551b adapted to the top plate opening 12f, a limit step 551a is formed between the two ends of the top plate 551b and the top plate 551, and when the top plate 551 rises to the limit step 551a to be abutted against the bottom surface of the card storage plate 12, the top plate 551 cannot rise any more, so as to achieve the purpose of limiting the top plate height of the top plate 551.
As shown in fig. 7 and 8, in the present embodiment, the card-pushing rod 553 is rotatably connected to the engaging lug 551c in the following manner: a card raising and avoiding groove 552 is formed on the connecting lug 551c, the card pushing rod 553 comprises a pushing rod joint 553a and a pushing arm 553b fixedly inserted with the pushing rod joint 553a, the pushing rod joint 553a is fixedly arranged at the end of the linkage rod 536, so that the linkage rod 536, the card raising rocker arm 532 and the card pushing rod 553 are linked; and the free end of the push arm 553b is provided with a card-ejecting roller 554 which is rollingly engaged with the card-raising escape groove 552.
The two engaging lugs 551c are also disposed on the top plate 551 of the present embodiment corresponding to the number of the rising swing arms 532, so as to ensure that the top plate 551 can ascend and descend smoothly along the receiving groove 61.
As shown in fig. 7, the card-raising and avoiding groove 552 in this embodiment has a groove bottom 522a at a lower position and a card-raising notch 522b at a higher position, the card-raising and avoiding groove 552 may be circumferentially closed, and an opening 522d for allowing the card-raising roller 554 to enter the card-raising and avoiding groove 552 may be disposed at the card-raising notch 522b, at this time, a second limit corner 522c should be ensured to be formed between the opening 522d and the card-raising notch 522b, so that the card-raising roller 554 can drive the card-raising plate 551 to move up and down along the receiving groove 61 at the card-raising notch 522b, and the card-raising and avoiding groove 552 cannot be separated from the card-raising and avoiding groove 552 at the opening 522 d.
Since the ejector pin 553 is linked to the swing arm 532, the ejector pin 553 changes its position when the swing arm 532 swings. As shown in fig. 8, when the card-raising roller 533 is located at the positioning notch 531aa of the card-raising curved groove 531a, the card-top roller 554 is located at the groove bottom 531ab of the card-raising escape groove 552; as shown in fig. 9, when the card-raising roller 533 rolls from the positioning notch 531aa to the groove bottom 531ab along the card-raising curved groove 531a, the card-ejecting roller 554 also rolls from the groove bottom 522a of the card-raising avoiding groove 552 to the card-ejecting notch 522b, but the rolling does not cause the card-ejecting plate 551 to lift, and when the card-ejecting roller 554 reaches the card-ejecting notch 522b, the card-ejecting roller 554 also reaches the card-ejecting notch 522b, so that the card-ejecting preparation is made; as shown in fig. 6, a card-pushing-out groove 555 communicated with the bottom of the card-lifting curved groove 531a is further formed on the card-lifting seat 531, and the card-pushing-out groove 555 extends from the bottom 531ab of the card-lifting curved groove 531a to a side away from the card-lifting plate 3 and coincides with the swing track of the card-lifting rocker arm 532; as shown in fig. 10, when the swing arm 532 continues to swing toward the shuffling barrel, the card-lifting roller 533 enters the card-pushing groove 555 from the card-lifting curved groove 531a, and since the swing tracks of the card-pushing groove 555 and the swing arm 532 coincide, the rolling of the card-lifting roller 533 in the card-pushing groove 555 does not cause the state of the card-lifting plate 3 to change, but causes the card-pushing push rod 553 and the card-pushing notch 522b to pull, so that the card-pushing plate 551 moves up along the receiving groove 61 to perform the card-pushing action, and at this time, the card-storing plate 12 starts to push the cards.
In order to avoid the card pushing plate 551 affecting the card storage plate 12, the embodiment is configured to: after the front end of the mahjong tiles on the tile storage plate 12 is lapped on the tile lifting plate 3, the tile pushing plate 551 can descend to release the jacking of the mahjong tiles. However, before this point, the top plate 551 is still in the top attitude, and the storage plate 12 is still moving during the top process, so as to avoid the top plate 551 obstructing the movement of the storage plate 12 during this stage, as shown in fig. 4, the width of the top opening 12f is greater than the width of the top plate 551. When the card storage plate 12 moves to push cards, the card pushing plate 551 moves relatively from the side of the card pushing port 12f close to the card outlet of the card storage plate 12 to the side of the card pushing port 12f far away from the card outlet of the card storage plate 12; then, the mahjong tiles are descended to release the jacking of the mahjong tiles, and the tile storage plate 12 continues to push the tiles until the mahjong tiles are completely transferred to the tile lifting plate 3.
As shown in fig. 11, a top card surface 551d is formed on the top card portion 551b, the top card surface 551d is inclined downward from the top of the top card portion 551b toward the card storage plate 12, and the inclination direction of the top card surface 551d is opposite to the advancing direction of the mahjong tiles on the card storage plate 12; the slope of the top card surface 551d is larger than that of the card storage platform 12a, so that the situation that the card storage plate 12 is not blocked to push the mahjong cards continuously when the top card 551 descends can be ensured, and the contact area between the mahjong cards and the top card surface 551d is larger and larger as the mahjong cards continue to move forwards, and the mahjong cards can be ensured to be kept stable in the card pushing process.
Correspondingly, as shown in fig. 2, in the curved groove 521 of the top card of the driving cam 52, the card pushing section 521b of the present embodiment is configured to include a top card section 521ba, a first-stage card pushing section 521bb and a second-stage card pushing section 521bc, which are connected in sequence, when the driving cam 52 rotates to make the top card section 521ba reach the card pushing roller 535, the card pushing roller 535 rolls along the top card section ba 521 to make the card lifting rocker arm 532 swing towards the shuffling barrel, the card lifting roller 533 rolls from the card lifting curved groove 531a into the card pushing avoiding groove 555, so that the top card pushing rod 553 lifts the top card plate 551; when the transmission cam 52 rotates to enable the first-stage tile pushing section 521bb to reach the tile loading roller 535, the tile loading roller 535 rolls along the first-stage tile pushing section 521bb, the tile lifting rocker arm 532 keeps unchanged in position, the tile pushing roller 542 rolls along the pushing section 541b from the pushing starting point 541d, and the mahjong tile part is horizontally pushed onto the tile lifting plate 3; when the transmission cam 52 rotates to enable the secondary pushing section 521bc to reach the card-loading roller 535, the card-loading roller 535 rolls along the secondary pushing section 521bc, the card-lifting rocker arm 532 swings to one side far away from the shuffling barrel, the card-lifting roller 533 returns to the card-lifting curve groove 531a from the card-lifting avoiding groove 555, and the card-lifting push rod 553 releases the jacking of the card-lifting plate 551; in the process, the tile pushing roller 542 continues to roll along the pushing section 541b to the middle point 541a of the track, and pushes the mahjong tile to the tile lifting plate 3.
Because the opening width of the card-pushing opening 12f on the card storage plate 12 is large, in order to ensure the strength of the card storage plate 12, as shown in fig. 4, a plurality of reinforcing ribs 12g arranged along the length direction of the card-pushing opening 12f are arranged on the inner edge of the opening of the card-pushing opening 12f, and a notch 551e matched with the reinforcing ribs 12g is formed on the card-pushing plate 551. The width of the reinforcing rib 12g should be smaller than the width of the mahjong tiles so as not to influence the supporting of the mahjong tile pushing plate 551 by the reinforcing rib 12 g.
As shown in fig. 2, the card-loading curved groove 521 includes an outer curved surface 521d and an inner curved surface 521e which are oppositely arranged, and during the rolling process of the card-loading roller 535 along the card-loading curved groove 521, the wheel surface of the card-loading roller 535 is always in rolling fit with the outer curved surface 521d and the inner curved surface 521 e; wherein, the outer curved surface 521d and the inner curved surface 521e are arranged vertically to the bottom surface of the mahjong tile pushing section 521bb at the starting point 521f of the curved surface slot 521 and at the first level; in other positions, the outer curved surface 521d and the inner curved surface 521e are both inclined with respect to the central axis of the transmission cam 52, so that the pushing and pulling of the card-handing push rod 534 can be realized. Wherein the inclination directions of the outer curved surface 521d and the inner curved surface 521e are different in the descending section 521a and the top section 521ba than in the secondary pushing section 521bc and the raising section 521c, which is consistent with the rolling direction of the card-raising roller 533. Wherein, the inclination angles of the outer curved surface 521d and the inner curved surface 521e gradually increase from the starting point 521f of playing cards to the end point of the top card section 521 ba; the inclination angles of the outer curved surface 521d and the inner curved surface 521e gradually decrease from the starting point of the secondary tile pushing section 521bc to the starting point 521f of the tile playing; at the end point of the card-pushing section 521ba and the beginning point of the secondary card-pushing section 521bc, the inclination angles of the outer curved surface 521d and the inner curved surface 521e are exactly the same as the total swing angle of the card-lifting rocker arm 532.
The mahjong machine tile pushing device of the embodiment has the working principle that:
when the mahjong-feeding motor 51 is started, the transmission cam 52 rotates along with the rotation of the transmission cam 52, and the mahjong-feeding curved-surface groove 521 and the mahjong-pushing roller 542 which are respectively positioned at the two sides of the transmission cam 52 respectively carry out corresponding actions under the driving of the transmission cam 52;
as the preparation of the previous stage of the card pushing action, as the transmission cam 52 rotates, the descending section 521a reaches the card loading roller 535, the card loading roller 535 rolls along the descending section 521a, the inner curved surface 521e presses the card loading roller 535, so that the card loading push rod 534 drives the card lifting rocker arm 532 to swing towards the direction of the shuffling barrel, the card lifting roller 533 rolls from the positioning notch 531aa to the groove bottom 531ab along the card lifting curved groove 531a, and the card lifting plate 3 descends until the card lifting plate 3 is arranged on the card storage plate 12; in the process, the card-ejecting roller 554 also rolls from the bottom 552a of the card-raising-avoiding groove 552 toward the card-ejecting slot 522b, but the rolling does not cause the card-ejecting plate 551 to rise or fall, and the card-ejecting roller 554 is ready for ejecting cards when the card-ejecting roller 554 reaches the card-ejecting slot 522 b;
when pushing the mahjong, the top mahjong segment 521ba reaches the mahjong loading roller 535 first, the inner curved surface 521e continuously presses the mahjong loading roller 535, so that the mahjong loading push rod 534 drives the mahjong lifting rocker arm 532 to continuously swing towards the direction of the shuffling barrel, the mahjong lifting roller 533 enters the top mahjong avoiding groove 555 from the mahjong lifting curve groove 531a, the state of the mahjong lifting plate 3 cannot be changed due to the fact that the swinging track of the top mahjong avoiding groove 555 is overlapped with that of the mahjong lifting rocker arm 532, but the state of the mahjong lifting push rod 553 and the mahjong lifting groove 522b are pulled due to the rolling of the mahjong lifting roller 533 in the top mahjong avoiding groove 555, so that the mahjong lifting plate 551 ascends along the accommodating groove 61 and pushes the mahjong upwards towards one end of the mahjong lifting plate 3;
in the process that the card feeding roller 535 rolls along the descending section 521a and the card pushing section 521ba, the card pushing roller 542 rolls from the track middle point 541a of the S-shaped card pushing track 541 along the pushing section 541b to the pushing starting point 541d to prepare for pushing cards; in this process, the rolling track of the card pushing roller 542 is exactly concentric with the rotating track of the transmission cam 52, so that the card storage plate 12 keeps the position unchanged;
