Description

A kind of riffling device of automatic mahjong-playing machine

Technical field

Mahjong has player widely in China and the world, is a kind of mass entertainmenting tool, and the mahjong machine of automatic card shuffling, code board is also very popular.The present invention proposes a kind of riffling device of suitable automatic mahjong-playing machine, particularly a kind ofly both can use nonmagnetic board also can use the riffling device of the automatic mahjong-playing machine of the board that is magnetic.

Background technology

Mahjong is the rich plays of four-player dominoes, is popular in especially in the Chinese culture circle, and the game rule of different regions is slightly different.The board formula of mahjong mainly contains " cake (civilian money) ", " bar (large rope) ", " ten thousand (ten thousand strings of cash) " etc.In ancient times, mah-jong pieces are actually the combination of a kind of playing cards and dominoes.The playing method complexity of mahjong is interesting, and its basic play is simple, easy left-hand seat, but wherein change extremely manyly again, matched combined varies with each individual, therefore become a kind of on Chinese history can attracting rich play form.

Modern mahjong machine is born in Japan, has the function of automatic card shuffling, code board, operation board demonstration.The operation principle of the mahjong machine that these are conventional is all the same, be all overlay coating on the back side of mah-jong pieces installed contain magnet etc. can with the piece of magnetic material of magnetic attraction, the front does not have.The magnetic force size is when facing the back side of mah-jong pieces according to the magnetosphere of mahjong machine, to attract by trump card; And during in the face of mah-jong pieces positive, because board has certain thickness, strength is weakened, be not enough to pick up mah-jong pieces.Board rotates with dish on the disk of an inclination, when board rises to eminence, the board that the back side makes progress is held by the magnetosphere on the bucket of shuffling, and rotate and deliver to delivery chute with magnetosphere, and push away motor and push into block of wood by folded at the head place, pushed away away by the chain bar, the board that faces up continues to rotate on dish, and the board on groove is built up is sent to the four sides two rear distribution by number by push rod.Have a little spring that board is turned on disk and dial, positive board is turned over downwards, upwards held by magnetosphere with the back side, to the last all boards all are sent on groove and take away.After the board at four sides was enough, by the lifting button on people's manipulation operations dish, the board that the supporting plate below board is folded the four sides was sent table top.The mahjong pieces table the inside has motor drives rotating disk and chain (push rod is arranged on chain) to rotate, and is automatically controlled by electronic chip.

Conventional mahjong machine has: the single port machine refers to only have a conveyer belt at the conveying board and through head motor showdown, and the chain motor send board, is raised at last on desktop by raising motor, as the term suggests be exactly the meaning of only having a delivery port; The four-hole machine is exactly four delivery tracks.And principle also can some difference, and its speed of shuffling is also confidential faster than single port, is generally about 30 seconds.The single port machine washing board time was generally about 70 seconds, wanted at the soonest about 55 seconds.

Early stage single port mahjong machine is taken the lead in inventing, producing by Japan the earliest, just begun by a small amount of imported with original packaging of Japan to China, afterwards because the market of China is huge, eighties of last century the early 1990s Japanese just opens factory in China and has produced automatic mahjong machine in enormous quantities, mahjong machine has been taken to China like this, from then on entered the fast-developing phase and form huge industrial chain.State-owned with sparrow friend leading (94 years begin China is introduced in the mahjong machine culture) at present, take a surname and, more than 500 manufacturing firms for mainly representing such as sparrow health, happy, the difficult to understand dragon of pine, good luck, vertical bright, upper island, mainly be gathered in Yangtze River Delta continent one band, Hangzhou Xiaoshan is the gesture of divergence as the mahjong machine distribution centre to the whole nation.

The operation principle of the mahjong machine of routine in the market is substantially similar, is all to utilize the piece of magnetic material in board to be realized shuffling by attraction and action such as code board etc.Shuffling of these automatic mahjong-playing machines is that the randomness of the board that pushed by the porch is determined, company when often playing cards due to the last time opens, folded, homochromy board together, push together the board after entrance, also very may sequentially enter conveying mechanism, make the probability of the related boards such as the identical suits caught between single player or adjacent player, identical type increase, thus the fairness that impact is played cards and the property guessed.

The utility model has proposed a kind of board that is magnetic that namely can use and can use the riffling device of the automatic mahjong-playing machine of nonmagnetic board again just for this defective and the deficiency of automatic mahjong-playing machine, for the popularization of automatic machine for mohjony game lays the foundation.

Summary of the invention

For namely using the board that is magnetic to use the automatic mahjong-playing machine of nonmagnetic board again, the present invention proposes novel automatic card shuffling mechanism, utilize the randomness of fully introducing in showdown, collection board, slide card process, realize the unpredictability of randomness, fairness and sequence that mah-jong pieces are shuffled.

The riffling device of a kind of automatic mahjong-playing machine of the present utility model, by collect the board body, the slide card body forms, collect the board body and be positioned at the top of slide card body, the entrance of board from the table top, the aperture of passing through the upper channel that collects the board body is pushed into and collects in the board body, process collects the aperture of the lower channel of board body again, passes the gap that collects between board body and slide card body and slips over the slide card external surface.

The riffling device of a kind of automatic mahjong-playing machine of the present utility model collect the board body, by two apertures that belong to respectively upper channel, lower channel, and the common hollow structure that forms of wall between two apertures.

The slide card body of the riffling device of a kind of automatic mahjong-playing machine of the present utility model, only under Action of Gravity Field, board can free down sliding at its outer surface.

The riffling device of a kind of automatic mahjong-playing machine of the present utility model, align with the table top entrance in the aperture that collects the upper channel of board body, and collecting between the aperture periphery of lower channel of board body and slide card external surface has the gap, and board batch passes from the gap.

The riffling device of a kind of automatic mahjong-playing machine of the present utility model collects in the board body puddler can also be installed.

The material of the board that can use in the utility model is hard material, refers to the harder solid material for the paper material of softer thin-walled, such as: solid-state plastics, pottery and resin etc.; Glass, timber, bamboo, stone material etc.; The ornament materials such as agate, jade, jewel etc.Board can be also the hierarchy of multiple material, and namely a kind of material of every one deck, link together mutually, can be also that each layer is same material, can be also that each layer is the various trait (color, hardness, density etc.) of same material.

No matter board is magnetic or not magnetic, the shape of board is generally the surperficial regular cuboid with round-corner transition, two surfaces up and down that the area of the cuboid of board is larger are the back side and front, the back side of all boards is light face or identical pictorial pattern and decorative pattern, and surface characteristic has uniformity.Corresponding word or pattern are carved with in the front of all boards, type have " cake ", " bar ", " ten thousand ", " east ", " west ", " south ", " north ", " in "; " Hair "; be carved with in addition " the white skin " of the middle tabula rasa of frame; and word or the patterns such as " plum ", " orchid ", " chrysanthemum ", " bamboo ", " spring ", " summer ", " autumn ", " winter " also has the board of joining of some region features.The type of the board of using and number are determined according to playing method separately by the player.Four sides in the front and back of the cuboid of board and left and right require smooth bright and clean, indefectible.The back side of board except require smooth bright and clean, indefectible, also require the surface textures such as color, pattern and decorative pattern pattern in use all boards want consistent, avoid becoming player's mark.

A plurality of boards are repeatedly stirred at random, mix at random the process that allows the people can not confirm wherein to sort rule is referred to as to shuffle, and completing the electromechanical assembly of shuffling is riffling device.

Conventional mahjong machine is to rely on magnetic principles work at present.The piece of magnetic material of the inside of board be arranged on from the back side of board close to, when the magnetosphere of mahjong machine and board near the time, can hold the back side of board one by one, and the internal magnetic material piece is installed the front of the board away from must be and just can not be held, needing dialling on swash plate turn over spring turns over it to dial and comes, allow its back side be lived by attraction, the board that holds constantly is transported in the mahjong tiles arranging machine structure again, then completes and shuffles and the action of code board.The randomness major part of shuffling depends on the randomness of the showdown action when trump card pushes entrance, and the mixed process of board in the rolling process of swash plate.No matter be several mouthfuls of machines (single port machine, four-hole machine, eight mouthfuls of machines etc.), the board that is pushed into often is deposited in the bottom of swash plate, and wait sequentially is inhaled into the swash plate rotation, and similar board probably again by code together.When being nonmagnetic, monoblock magnet or other monoblock piece of magnetic material that the inside of the whole board of its expression all is not attracted are to complete the action of shuffling fully on traditional automatic mahjong-playing machine when board.

The operation principle of the mahjong machine of routine in the market is substantially similar, is all to utilize the piece of magnetic material in board to be realized shuffling by attraction and action such as code board etc.The randomness major part of shuffling of these automatic mahjong-playing machines is that the random action of the board that pushed by the porch is determined, and the impact of the mixability of board in the rolling process of swash plate.Company when often playing cards due to the last time opens, folded, homochromy board together, push together the board after entrance, also very may sequentially enter conveying mechanism, make the probability of the related boards such as the identical suits caught between single player or adjacent player, identical type increase, artificial factor is often arranged therein, thus fairness and unpredictability that impact is played cards.The utility model proposes for the problems referred to above just.

automatic mahjong-playing machine, generally comprised table top, operation board, controller, perceptron, riffling device, the mahjong tiles arranging machine structure, supporting seat, pedestal, power supply and accessory, supporting seat is arranged on pedestal, supporting seat is supporting table top, the upper surface of table top is furnished with the import of board, outlet and operation board, riffling device and mahjong tiles arranging machine structure have been installed in the following cavity of table top, controller connects perceptron, operation board, riffling device, mahjong tiles arranging machine structure and accessory, each road information of perceptron perception mahjong machine, controller is controlled riffling device, the athletic performance of the parts such as mahjong tiles arranging machine structure and operation board.

The table top of mahjong machine provides a player's the place of playing cards, for the player take domino, manage board, deposit board, the action needs of the management board such as play a card, be also the place that has the accumulation of certain area and deposit board.

The upper surface of table top is equipped with operation board, operation board is controlled by the controller also and the controller exchange message, banker in the player who the plays mahjong relevant operation informations such as position, the number of times of winning the game, dice throwing and dice throwing number of times of being the banker are provided, by other appreciable aspects such as photosignal or voice signals, the panel by operation board conveys to all players to controller with these operation informations.Also have action button and the switch of relevant mahjong machine above operation board.

The upper surface of table top has the entrance and exit of board, is respectively the outlet of table top entrance and table top.After the shuffling of board, the action of code board were completed, mahjong tiles arranging machine structure trump card was fitly released from the table top exit on face down ground at the back side up according to the number of plies of setting, columns (pier number), respectively equably by the piling front every player in a row.After every innings of board is played and is finished, players is opened the table top entrance, and boards all on table top is pushed the table top entrance, after closing the upper table surface entrance, riffling device is completed the action of shuffling automatically, and receiving after the signal of playing cards the mahjong tiles arranging machine structure can release the complete board of piling from the table top outlet.

Be designed with specific cavity below table top, other accessories such as riffling device, mahjong tiles arranging machine structure have been installed in cavity.The riffling device of a kind of automatic mahjong-playing machine of the present utility model just is placed in platform basifacial space.

The riffling device of a kind of automatic mahjong-playing machine of the present utility model, by collect the board body, the slide card body forms.

The riffling device of a kind of automatic mahjong-playing machine of the present utility model collect the board body, by belonging to respectively the upper channel that collects the board body, two apertures of lower channel, and the hollow structure of the composition of the wall between these two apertures, the volume of the cavity of this hollow structure makes whole secondary board to be contained in cavity greater than the volume of all boards.The aperture of upper channel and the aperture of lower channel all are positioned at plane or curved surface separately, align with the entrance of table top in the aperture of upper channel.So-called alignment, the center line that is exactly the aperture of upper channel overlaps substantially with the center line of the entrance of table top, and the orifice diameter of upper channel is more than or equal to the diameter of the entrance of table top, so just make the board that is pushed into after the table top entrance can only all enter the aperture that collects board body upper channel, the entrance of table top is opened rear board and can all be received in cavity below the upper channel aperture.

The player opens the table top entrance after one innings of board finishes, the board on table top randomly, is all advanced the table top entrance, completes the showdown action, then enters through the aperture of the upper channel that collects the board body and collect the board body.This process is the introducing of randomness once, may know originally in other words that the variation of randomness had all occured position, speed, the direction of motion of board in the showdown process of board face pattern, and the number that at every turn pushes board is also random.

After showdown finished, board may collide between part board and board in push-on process, and the part board also will collide with the inside wall that collects the board body, and all boards all will fall under Action of Gravity Field, the place, aperture of the lower channel within collecting the board body that reassembles, and this is collection board process.Can introduce again the randomness of the distribution of a board in collection board process, this time the random distribution of board depends on that board is at the direction of motion, movement velocity, the motion mode in space, and the collision process between each board, also depend on simultaneously board and collect the inside wall impact strength of board body, the direction of falling and being scattered after collision.That is to say board in colliding, being scattered, falling, assembling each process, its state is to be difficult to prediction, will be the place, aperture that is accumulated in randomly the lower channel that collects the board body at last.

Big or small limited due to the aperture of lower channel, collect like this board in the board body in this same zonule by all will be in the aperture before collecting the gap between board body and slide card body, then the surface along the slide card body disperses landing randomly, equably in all directions downwards, and this is the slide card process.At this moment the board that initially pushes is deposited in together in same zonule randomly, and may along the free landing in slide card surface on all directions, enter in the mahjong tiles arranging machine structure.The landing process is under the frictional force, air drag acting in conjunction on pressure, surface of upper strata board in self gravitation, zone at board, and mutually collides between board during landing and to carry out in disturbance, and randomness is introduced in the process of shuffling again.In this process, the power of all boards only derives from the gravity of board.

By the introducing of the randomness in showdown, collection board, three processes of slide card, shuffle very abundant.

The outer surface of the slide card body of the riffling device of a kind of automatic mahjong-playing machine of the present utility model requires board to get final product free landing under the self gravitation effect.Its outer surface will have certain smoothness, and gradient is moderate, can not allow only self-locking in the down sliding process under the self gravitation effect of board, can realize that board is in its outer surface free function of landing downwards under Action of Gravity Field only.Gradient and smoothness are both comprehensive, and board is concrete structure, the surface flatness of free landing downwards and surface under Action of Gravity Field, and the performance of material is all relevant, can by experiment and calculate.The surface is smooth, but can not be smooth, and what the part can arrange suitable protuberance has smooth excessive boss with the slide card surface, increases disturbance in board landing process.

The slide card body is positioned at the below that collects the board body, and slide card external surface and collect between the periphery in aperture of board body lower channel a segment distance is arranged becomes a gap, and this gap wants to allow board pass, then, board under Action of Gravity Field along the free landing of slide card external surface.What of the speed that board passes and the board that once passes are the size in gap determined, minimum gap is greater than the shortest size of board.The shortest size of board be the length of board, highly, in thickness minimum one, minimum gap refers to collect the aperture periphery of lower channel of board body and the minimum space vertical range between the slide card external surface.In the gap, a certain moment once passes a plurality of boards and is and batch passes.

The riffling device of a kind of automatic mahjong-playing machine of the present utility model can also have the another kind of structure under same design, can within collecting the board body, puddler be installed exactly, shuffles more fully and assists board to pass from the gap.Puddler is a revolvable shaft-like part, and its rotating shaft axis is parallel with the center line that collects board body lower channel aperture.Along one or more crosspiece has been installed on the vertical direction of its axis, crosspiece can be a bit of straight quarter butt, can be also the quarter butt of curve.In puddler when rotation,, crosspiece will stir in the mah-jong pieces heap the inside of assembling, and increase the randomness of board, and board falls in process collect board body the inside, also increases collision, the upset of board, increase randomness and randomness.In whipping process, also can squeeze showdown, help board to pass from the gap, prevent card.When puddler did not rotate, when board is pushed into when collecting in the board body, board fell in process collecting board body the inside, also increases the collision of board and puddler, from and increased collision, the upset of board, increase randomness and randomness.

The riffling device of a kind of automatic mahjong-playing machine of the present utility model can realize that all mah-jong pieces that table top entrance place pushes were random disordered state before entering the mahjong tiles arranging machine structure, then enter the mahjong tiles arranging machine structure.

The riffling device of a kind of automatic mahjong-playing machine of the present utility model can use magnetic board or not magnetic board, and wide application for the upgrading of present automatic mahjong-playing machine provides possible technological reserve, has wider application prospect.
