Description

Mahjong machine, stacking and pushing device thereof and method for stacking and pushing mahjong pieces

[ field of technology ]

The invention belongs to the field of mahjong machine manufacturing, and particularly relates to a mahjong machine, a stacking and pushing device thereof and a method for stacking and pushing mahjong pieces.

[ background Art ]

The mahjong tile is also called sparrow tile (also called horse hanging), which is a game invented by ancient Chinese people, and the tile entertainment appliance is made of bamboo, bone or plastic, on which patterns or words are carved, and is a game attended by four people, and the rules of the game in different areas are slightly different. A set of mahjong tiles comprises 3 basic colors of ten thousands, cakes and strips, which are called: mo Zi cards (ten thousand), cheeses (cakes) and slivers (ropes), 4 cards from one to nine, and twenty-seven 108 cards in total; and 4 cards of east, south, west, north, middle and white are added, and seven 28 cards are added; 136 cards in total, which is also called as 'plain mahjong' in normal times. Then, eight cards with similar functions to the king (JOKER) in the playing cards are added, namely: "spring, summer, autumn, winter, plum, blue, bamboo, chrysanthemum" and one hundred forty-four cards, which form what we said "mah-jongg with flowers". And 8 wild cards are arranged. Thus, a complete deck of mahjong tiles (74 tiles in some areas) includes words, flowers, ordinal numbers, and wild cards. The popular is simplified mahjong, which does not contain wild cards and large white boards, and has 144 pieces. Compared with other domino forms, the playing method of the mahjong is the most complex and interesting, the basic playing method is simple and easy to get on hand, but the variation is very large, and the matching combination is different from person to person, so the mahjong becomes one of the most attractive domino forms in China historically.

Along with the continuous improvement of the standard of living, people pay more attention to leisure, entertainment and life, and the convenient and labor-saving automatic mahjong machine is gradually favored by people.

Because the existing four-port automatic mahjong machine is limited by the structure of the pushing and lifting mechanism, two mahjong tiles are stacked together to be played when the mahjong tiles are pushed and lifted, and only one row of mahjong tiles is arranged in front of each person on the table top. The utility model discloses a pushing and lifting mechanism of automatic mahjong machine as disclosed in patent document with publication number CN201164721, it includes the lattice board, stores up the tablet board and sets up respectively in the device of holding in the palm of tablet board both sides and pushes away the tablet device, hold in the palm the tablet device and include layer board, layer board strutting arrangement and hold in the palm the tablet cam by motor drive, hold in the palm the tablet cam on be equipped with the connecting rod, the layer board below is equipped with the layer board support that has the waist hole, connecting rod one end activity sets up in the waist hole, is equipped with the sensor at the middle part of storing up the tablet board, because this pushing and lifting mechanism has only a fixed tablet board of storing up, therefore this pushing and lifting mechanism can only release a row of tablet each time, when beginning playing, need artifical twelve or thirteen cards of grabbing the play. In order to make up the defects of the existing four-port mahjong machine, an eight-port mahjong machine is developed in the industry, twelve or thirteen cards required for starting are also piled up and pushed out, but the existing eight-port automatic mahjong machine needs to be provided with an inner card discharging groove and an outer card discharging groove on four sides of a panel respectively, so that the strength of the panel is greatly reduced, and the problems of warping, deformation and the like generated after the strength of the panel is reduced, and the problems of difficult machine adjustment or incapability of adjustment are caused. And the outer card outlet groove of the existing eight-port automatic mahjong machine is too far outside and is overlapped with the position where 13 cards are placed by a user, so that the user is easy to feel uncomfortable when using the mahjong machine.

Accordingly, patent documents with publication numbers CN201727950U, CN201578846U, CN101934142U and the like disclose a tile lifting mechanism capable of enabling a four-port automatic mahjong machine to complete the functions of an eight-port automatic mahjong machine, and patent documents with publication numbers CN101983745, CN203370275U, CN203436804U, CN202446789U and the like disclose a stacking device capable of stacking and pushing three pieces of mahjong, and the stacking device is suitable for a mahjong machine of a flat pushing tile loading mode.

However, in the prior art, one stacking and pushing device can only stack and push two mahjong tiles, or can only stack and push three mahjong tiles, and the same stacking and pushing device can not stack and push three mahjong tiles and can also stack and push two mahjong tiles, so that the existing stacking and pushing device lacks versatility, and the functions of an eight-mouth machine and a four-mouth machine cannot be simultaneously realized on the same mahjong machine or the same stacking and pushing device; in addition, in some mahjong playing methods, the number of mahjong tiles taken by a square player is inconsistent with the number of mahjong tiles placed in front of the square player, and the existing stacking and pushing device for stacking only three mahjong tiles cannot be adopted, so that the existing mahjong machine with eight-mouth machine function cannot play the mahjong playing methods.

The patent document with publication number of CN203370275U discloses a curve wheel for a mahjong machine tile pushing head, a detection element is adopted to detect positioning magnetic steel to position the curve wheel, and when the curve wheel is respectively positioned at three different positions, signals of the positioning magnetic steel detected by the detection element are different, namely, the coding thought is adopted, different codes are represented by distinguishing the number and the positions of the positioning magnetic steel, namely, the outer circumference of the curve wheel is provided with a left annular coding belt and a right annular coding belt for fixing the magnetic steel, when the detection element carries out magnetic steel identification, the first left magnetic steel and the first right magnetic steel on the left annular coding belt can be detected simultaneously, the code is 11, the second left magnetic steel on the left annular coding belt is detected singly, the code is 10, the second right magnetic steel on the right annular coding belt is detected singly, the code is 01, thus, the three positioning positions of a tile bearing table can be distinguished, the layout avoids the occurrence of repeated positioning faults, and the stacking of three mahjong tiles can be realized. However, the stacking and pushing device (the tile pushing head) adopting the tile supporting cam (the curve wheel) cannot realize stacking and pushing of two mahjong tiles, so that the stacking and pushing device and the mahjong machine are poor in universality.

In the card pushing slider structure of the prior art, as shown in fig. 26, when the bottom end of the arc-shaped card pushing slot 4064 of the card pushing slider 406 is located right below the rotation center of the card pushing roller 4072, the card pushing roller 4072 can only rotate in one direction (clockwise). When the card pushing block rotates anticlockwise, due to the limitation of the arc card pushing groove 4064 of the card pushing block 406, the card pushing block 406 is limited by the frictional force between the card pushing block and the guide rod, which is smaller than the thrust of the card pushing roller 4072 for rightward sliding, so that the card pushing block 406 cannot move rightwards, and in the stacking pushing device adopting the card pushing block, only one linkage matching relationship exists between the card pushing head and the card bearing table.

The publication number CN101983745B discloses a method and a device for receiving mahjong pieces of a mahjong machine, wherein the sliding groove of the tile pushing sliding block consists of a section of straight groove and a section of circular arc groove, and the tile supporting cam is provided with three continuous guide surfaces with different heights, so that the problem is also solved, namely, when the tile pushing sliding block is at a specific position, the tile pushing roller can only rotate in one direction to drive the tile pushing sliding block to slide left and right, and the tile supporting cam can only rotate in one direction to drive the tile supporting roller and the swing arm to move up and down, so that the tile pushing head and the tile supporting table have only one linkage matching relation.

3) After detecting that the second mahjong tile is in place, the tile holding table 402 descends again to the third height, and in the descending process, the tile feeding device is prevented from feeding the third mahjong tile;

4) The tile pushing head 401 pushes two stacked mahjong tiles onto the tile storage board 404.

In one embodiment of the invention, the card sending device is provided with a blocking device for preventing the mahjong cards from being sent out; when two mahjong tiles are stacked, the blocking device prevents the third mahjong tile from being sent out by the tile sending device in the process that the tile bearing table 402 descends from the second height to the third height. The blocking device can be arranged at a card outlet of the card feeding device, such as a blocking assembly disclosed in patent document with publication number of CN 205964958U; the blocking device can also be a card feeding port or an internal part of the card feeding device, such as a card feeding component one by one in the publication No. CN 103157278A and an electric control gate in the publication No. CN 204601595U. When the two mahjong pieces are stacked and pushed, the blocking device is adopted to prevent the third mahjong piece from being sent out, so that the linkage matching relation of the three mahjong pieces can be used along with the stacking and pushing of the mahjong pieces, the hardware of the existing mahjong machine is not required to be changed, only the control circuit is required to be modified, namely, after the control circuit detects that the second mahjong piece is in place, two execution signals are generated, firstly, the blocking device is started to prevent the third mahjong piece from being sent out, secondly, whether the third mahjong piece is in place or not is not required to be detected, and the mahjong pieces can be pushed by the mahjong piece pushing head. Of course, in other embodiments of the present invention, the two execution signals may also be implemented in combination with a counting device in the tile feeding device, for example, when the counting device detects that two tiles enter or exit the tile feeding channel, that is, the blocking device is started to stop the third tile from being sent out, and when the two tile stacking mode is switched to, the in-place detection of the third tile may be closed. The blocking device is in linkage fit with the tile pushing head and the tile supporting table of the stacking and pushing device, and although the free switching between stacking and pushing of two tiles and stacking and pushing of three tiles can be realized on the same stacking and pushing device and the mahjong machine, the frequent electric control action of the blocking device can cause the reduction of reliability and service life, and the efficiency of the mahjong machine for sorting the mahjong tiles is greatly affected.

In another embodiment of the present invention, when two mahjong tiles are stacked and pushed, the tile pushing head 401 starts pushing the two stacked mahjong tiles in the process that the tile supporting table 402 descends from the second height to the third height, so that the tile pushing head 401 can block the tile outlet of the tile feeding device, and the tile feeding device is prevented from feeding the third mahjong tile. The tile outlet of the tile feeding device is blocked by the advance intervention of the tile pushing head, the reliability and the service life reduction caused by the frequent electric control action of the blocking device are overcome, and the mahjong tile arranging efficiency of the mahjong machine is higher. However, the mode of inserting the card pushing head in advance requires that the card pushing head and the card bearing table in the stacking and pushing device adopt different linkage coordination relations when three cards are stacked and two cards are stacked and pushed, and an internal linkage mechanism of the stacking and pushing device needs to be improved.

In one embodiment of the invention, the pusher head 401 pushes the mahjong tiles from the tile receiving platform 402 above the third height to the tile storage board 404. Thus, the tile storage board 404 is higher than the top of the tile-holding table 402 at the third height, i.e. the tile-holding table is lifted a certain distance after being lowered to the third height, and then the tile-holding table is pushed up by the tile-pushing head to the tile-holding board, so that the height of the main machine of the mahjong machine can be reduced, and the machine is thinner, but when two pieces of mahjong are stacked and pushed, if the tile-pushing head is used for inserting in advance, the method of blocking the tile-holding table is difficult to implement, and therefore, the blocking device is preferable.

In another embodiment of the present invention, the pusher head 401 pushes mahjong tiles from the tile holding table 402 at the third height to the tile storage plate 404. In this way, the deck 404 is no higher than the top of the deck 402 resting at the third height. Thus, when two mahjong pieces are stacked and pushed, a mode of inserting the mahjong pieces in advance or a mode of blocking the mahjong pieces can be adopted.

As shown in fig. 4 and 5, when the card table 402 is at the first height, the card bearing roller 4082 is located at the first card bearing position a in the card bearing curved slot 4071, and the card pushing roller 4072 is located at the first card pushing position a' in the card pushing curved slot; when the card bearing table 402 is at the second height, the card bearing roller 4082 is positioned at a second card bearing position B in the card bearing curved slot 4071, and the card pushing roller 4072 is positioned at a second card pushing position B' in the card pushing curved slot; or when the card bearing table 402 is at the second height, the card bearing roller 4082 is positioned at a fifth card bearing position E in the card bearing curve slot 4071, and the card pushing roller 4072 is positioned at a fifth card pushing position E' in the card pushing curve slot; when the card table 402 is at the third height, the card bearing roller 4082 is positioned at the third card bearing position C to the fourth card bearing position D in the card bearing curved slot 4071; when the card bearing roller 4082 is positioned at the fourth card bearing position D in the card bearing curved slot 4071, the card pushing roller 4072 is positioned at the fourth card pushing position D' in the card pushing curved slot; wherein, in the card bearing curved slot 4071, the second card bearing position B and the fifth card bearing position E are respectively located at two sides of the first card bearing position a, the first card bearing position a and the fourth card bearing position D are respectively located at two sides of the fifth card bearing position E, the first card bearing position a and the third card bearing position C are respectively located at two sides of the second card bearing position B, and the part of the card bearing curved slot 4071 between the third card bearing position C and the fourth card bearing position D is in a circular arc shape (the circular arc is concentric with the rotation center of the card bearing cam); the card pushing curve groove comprises an upper end section 4061, a middle circular arc section 4062 and a lower end section 4063 which are sequentially connected, a first card pushing position A ', a second card pushing position B', a fourth card pushing position D 'and a fifth card pushing position E' are arranged on the middle circular arc section 4062, the second card pushing position B 'and the fifth card pushing position E' are positioned on two sides of the first card pushing position A ', the fourth card pushing position D' and the first card pushing position A 'are positioned on two sides of the fifth card pushing position E', and the second card pushing position B 'and the fourth card pushing position D' are respectively positioned at the connection parts of the middle circular arc section 4062 and the lower end section 4063 and the upper end section 4061. The radian of the middle arc section 4062 is consistent with the rotating arc of the card pushing roller.

The distance from the card bearing roller 4082 to the rotation center of the card bearing cam 407 in the first card bearing position a > the distance from the card bearing roller 407 in the second card bearing position B = the distance from the card bearing roller 407 in the fifth card bearing position E > the distance from the card bearing roller 407 in the third card bearing position C = the distance from the card bearing roller 407 in the fourth card bearing position D. Thus, two methods can be adopted in the matching action process of the card bearing cam and the card pushing slide block: firstly, a card bearing cam rotates anticlockwise, a card bearing roller descends to a first height, a second height and a third height in sequence in a card bearing curve groove from A to B to C to D to E to A, then ascends to the first height from the third height, meanwhile, a card pushing roller firstly descends to B ' from A ' in the card pushing curve groove, a card pushing head is not moved, then descends to a lower end section from B ' to upward to B ' to A ' to E ' to D ' to an upper end section and returns to D ', card pushing and resetting are completed, and then the card pushing head is not moved from D ' to E ' to A '. Secondly, the card bearing cam rotates clockwise, the card bearing roller descends to the first height, the second height and the third height in sequence in the card bearing curve groove from A to E to D to C to B to A, then ascends to the first height from the third height, meanwhile, the card pushing roller moves from A ' to E ' to D ' in the card pushing curve groove, the card pushing head is not moved, then moves from D ' to the upper end section, moves from D ' to E ' to A ' to B ' to the lower end section, returns to B ', card pushing and resetting are completed, and then the card pushing head is not moved from B ' to A '. Therefore, by arranging two sets of different linkage coordination relations on the tile pushing head and the tile supporting table, when the two mahjong tiles are stacked and pushed, the two stacked mahjong tiles are inserted in advance by arranging the tile pushing head, so that the third mahjong tile is prevented from being sent out, the conventional motor can be used for realizing the rapid switching of stacking and pushing the two mahjong tiles or stacking and pushing the three mahjong tiles by the stacking and pushing device through selecting the rotation direction of the motor, the same stacking and pushing device can realize the stacking and pushing of the three mahjong tiles, the stacking and pushing of the two mahjong tiles can be realized, the universality of the stacking and pushing device and a mahjong machine is improved, the die opening cost and the manufacturing cost are reduced, the playing method of the mahjong machine is more, and the user experience and the comfort are better.

In order to ensure that the card pushing head can be inserted in advance to push the two mahjong tiles when stacking and pushing the two mahjong tiles, the time distance from A ' to E ' to D ' of the card pushing roller 4072 is longer than the time distance from A ' to B ', in this embodiment, a simpler method is adopted, namely, a first card pushing position A ', a second card pushing position B ', a fourth card pushing position D ' and a fifth card pushing position E ', and the middle arc section 4062 of the card pushing curved slot is trisected.

The upper end section 4061 and the lower end section 4063 determine the card pushing speed of the card pusher head. The upper end section 4061 and the lower end section 4063 are straight grooves, the upper end section 4061 and the lower end section 4063 are arranged at an included angle with the vertical direction, and the card pushing curved grooves are arranged symmetrically up and down.

The circumference of the card bearing cam 407 is provided with sensing components which are respectively arranged in one-to-one correspondence with a first card bearing position A, a second card bearing position B, a fourth card bearing position D and a fifth card bearing position E, and the shell 410 is provided with a position sensor 405 for detecting the sensing components. Therefore, whether the mahjong tile carrying table reaches each position can be effectively monitored, so that the stacking and pushing motor is controlled to stop at the corresponding position, and mahjong tile in-place signals are waited. In this embodiment, the sensing component is a plurality of magnetic steels arranged in left and right annular channels, the two magnetic steels correspond to the first license plate position a, the one magnetic steel on the right corresponds to the second license plate position B, the one magnetic steel on the right corresponds to the fourth license plate position D, and the one magnetic steel on the left corresponds to the fifth license plate position E. In other embodiments, other sensors are possible, such as an optical eye code wheel configuration. The sensor for detecting the rotation position of the card bearing cam can be in a direct detection mode or an indirect detection mode, for example, the card pushing sliding block, the card pushing head or the card bearing table is subjected to position detection to obtain the corresponding position information of the card bearing cam, and the position information of the card bearing cam is converted by recording the rotation stroke information of the stacking pushing motor if a stepping motor or a motor with the position sensor is adopted. In addition, a mahjong viewing sensor, such as an optical eye or other proximity sensor, for detecting whether mahjong tiles are sent out in place or not is arranged on the mahjong tile blocking frame or the mahjong tile pushing head. The sensor may be a hall sensor, a photoelectric sensor, an ultrasonic sensor, or a contact sensor such as a limit switch.

As shown in fig. 4 and 5, the radian of the middle arc section 4062 of the card pushing curve slot is a; on the card bearing curved slot 407, the rotation angle of the card bearing cam between the first card bearing position A and the second card bearing position B is B, the rotation angle of the card bearing cam between the second card bearing position B and the third card bearing position C is C, the rotation angle of the card bearing cam between the third card bearing position C and the fourth card bearing position D is D, the rotation angle of the card bearing cam between the fourth card bearing position D and the fifth card bearing position E is E, the rotation angle of the card bearing cam between the fifth card bearing position E and the first card bearing position A is f, and the included angle formed between the connecting line of the central axis of the card pushing roller 4072 and the rotation center of the card bearing cam and the vertical direction is h; wherein, a is more than or equal to 45 degrees and less than or equal to 170 degrees, b is more than or equal to 0 degrees and less than or equal to 90 degrees, c is more than or equal to 15 degrees and less than or equal to 90 degrees, d is more than or equal to 160 degrees and less than or equal to 315 degrees, e is more than or equal to 15 degrees and less than or equal to 75 degrees, f is more than or equal to 0 degrees and less than or equal to 90 degrees, k is more than or equal to 30 degrees and less than or equal to 150 degrees, m is more than or equal to 15 degrees and less than or equal to 165 degrees, k=e+f, m=b+c, and h is more than or equal to 0 degrees and less than or equal to 150 degrees. By adopting the arrangement, the tile pushing curve groove and the tile bearing curve groove can realize that two sets of different linkage coordination relations are arranged on the tile pushing head and the tile bearing table, and when two mahjong tiles are stacked and pushed, the pushing head is arranged to interpose the two stacked mahjong tiles in advance, so that the third mahjong tile is prevented from being sent out.

In this embodiment, the height of the deck drops slowly and then quickly as the card bearing cam rotates from the second card bearing position B to the third card bearing position C. I.e. the cam curve between B and C is convex. Thus, the carrying table can be matched with the intervention condition of the tile pushing head to more reliably prevent the third mahjong tile from being sent out.
