The specific embodiment
The mah-jong pieces that flop mechanism of the present invention adopted are being taken advantage of with its length and the formed face of lying on one's side of width when crouching in a bearing-surface, and its center of gravity G is partial to the front or reverse side one side of board.This board is different along the Density Distribution of board thickness direction, the front or reverse side one side that make the center of gravity of board be partial to board, and its concrete structure can be multiple, and the present invention will lift following three examples and explain, but never be limited to the embodiment that is lifted.
Please with reference to Fig. 1, these mah-jong pieces are formed by connecting the material of two kinds of different densities.The side that this board forms with its length L and thickness B is taken advantage of and is crouched on bearing-surface;, wherein Fig. 1 a is the state of lying on one's side of this board, Fig. 1 b and Fig. 1 c are respectively the left and right views of mah-jong pieces shown in Fig. 1 a; The positive Z and the reverse side F that have shown this board respectively, the length of this board is that L, width are that S, thickness are B.The material example of two kinds of above-mentioned different densities is processed the rectangular block 1a and the rectangular block 1b of thickness difference (being respectively B1, B2) respectively.This two rectangular block 1a, 1b are docked along thickness direction; For example both are consolidated into one through mold pressing or injection moulding process; Form mah-jong pieces 1, because this board is along board thickness direction upper density skewness, and the density of front one end of board is big; So the center of gravity G of board is partial to the geometric center C of board near positive Z one side of board.The center of gravity thickness of this board is BG2, and to be this board center of gravity G be divided into two sections BG1, BG2 with the thickness B of this board to center of gravity thickness, and one section wherein relatively long BG2 length is center of gravity thickness.
See also Fig. 2, these mah-jong pieces are also processed by the material of two kinds of different densities.With the relatively little material of density for example common plastics process as board shape cavity cuboid; This chamber cuboid is made up of box body 1.1b that comprises the positive Z of board and the lid 1.1a that comprises board reverse side F; Material building stones that for example density is high or iron with density is big are relatively processed and rectangular block 1.2; This rectangular block 1.2 is suitable and place in the cavity corresponding to positive Z one end of board box body with cavity, is connected on the inside bottom surface of bottom, near the end of the positive Z of board.With lid 1.1a through mold pressing or other general technological means sealing-ins at opening one end of box body 1.1b, form mah-jong pieces 1.This board center of gravity is partial to positive Z, and is partial to the side of the geometric center C of board.According to the foregoing description, there is center of gravity thickness B G2 equally in this board.
See also Fig. 3, these mah-jong pieces are processed with a kind of material.Inboard along the thickness direction of board is provided with cavity, for example in the inboard near said board reverse side F one end cavity is being set, and makes density near said board reverse side one end less than the density of board near the positive end of board.Make said board different along the Density Distribution of thickness direction.Its concrete structure also can be made the structure of above-mentioned box body 1.1b and lid 1.1a, and is just much bigger than the box bottom thickness H2 near board reverse side one end near the box body bottom thickness H1 of the positive end of board, makes center of gravity G be partial to the positive end of board.Can certainly as required center of gravity be partial to board reverse side one end, this is thing easily for a person skilled in the art.According to the foregoing description, there is center of gravity thickness B G2 equally in this board equally.
Above-mentioned mah-jong pieces are placed flop mechanism of the present invention, just can realize identification of board face and arrangement above-mentioned mah-jong pieces.Concrete structure in the flop mechanism such as following embodiment, but be not limited to the embodiment that lifts.
Map 4~Fig. 5, flop mechanism mainly are made up of with identification slot 20 defeated board groove 10, and identification slot 20 places defeated board groove 10 both sides and is lower than defeated board groove position.Defeated board groove 10 is used to carry the above-mentioned board of lying on one's side; Mainly form by two parallel spigot surface 11a, 12a, inclined thrust surface 13a and the conveyer belt 14 that is arranged between the two parallel spigot surfaces; Parallel spigot surface 11a, 12a depend on the guide plate 11,12 of corresponding pair of parallel; The gap ratio board thickness B of two parallel spigot surfaces is more bigger, guarantees that like this board on the conveyer belt is passed with the attitude of lying on one's side abreast.The width D of conveyer belt 14 drops on outside the conveyer belt plane center of gravity of the board of lying on one's side less than the center of gravity width B G2 of the face of lying on one's side.Spigot surface 13a depends on the two parallel guide plates 13, is this two guide plates opposed inside face.Two spigot surface 11a, the last board turning breach that is respectively equipped with of 12a, this two board turnings breach is pressed the front and back position setting of conveyer belt traffic direction, board turning breach 18a and back board turning breach 18b before being respectively.Inclined thrust surface 13a is arranged on the spigot surface 12a relative with back board turning breach 18b, being connected on the guide plate 13 and being positioned at the centre-height place of guide plate of this derivation board.Conveyer belt width D is less than the center of gravity thickness B G2 of said board, and the center of gravity that makes the board reverse side be close to the board of spigot surface 11a like this drops on outside the conveyer belt plane, and the rollover at preceding board turning breach 18a place falls into corresponding identification slot 20.The board that the board reverse side is close to spigot surface 11b is pushed against by inclined thrust surface 13a, and center of gravity is dropped on outside the conveyer belt plane, and the rollover of board turning indentation, there equally also falls into corresponding identification slot 20 in the back, and the board that rollover falls into identification slot 20 forms the reverse side flat board that crouches up.Identification slot 20 main one comprises the parallel spigot surface of conveyer belt 24, two and places the conveyer belt between this two spigot surface; Defeated board groove is communicated with by the upset breach with identification slot.
Identification slot 20 comprises conveyer belt 25 at least, can be passed abreast for making the flat board that crouches on it, and present embodiment adopts spigot surface 21a, the 22a of pair of parallel, and conveyer belt 25 is placed between this two spigot surface.Spigot surface 21a, 22a are attached on the corresponding a pair of guide plate 21,22, and the width S of the spacing board of two parallel spigot surfaces is bigger, can keep the flat prone position attitude of the board on the conveyer belt so preferably.Fail the conveyer belt the 14, the 24th in board groove 10 and the identification slot 20, be respectively the conveyer belt of closed loop, all at least two by correspondence transmit the transmission of running roller (not shown)s.
When mah-jong pieces 1 of the present invention are transferred in above-mentioned flop mechanism, be in guide plate 12 1 sides like the front of mah-jong pieces, reverse side F nestles up guide plate 11, takes advantage of and crouches on the conveyer belt 14 of lying on one's side, referring to the residing a of the board among Fig. 4 position and corresponding Fig. 5 a.Under conveyer belt 14 transmissions and spigot surface 11a, 12 a guiding; Board 1 is parallel move run to before during the b position at upset breach 18 places; Because of dropping on, the center of gravity of constraint guiding board that spigot surface 12a is not arranged produces rollover outside the face of lying on one's side; On the conveyer belt 24 of the identification slot 20 below falling, making the board in the identification slot unit all is the board that reverse side makes progress, and sees also the residing b of board position and corresponding Fig. 5 b among Fig. 4.
Have the positive Z of character to nestle up guide plate 11 like mah-jong pieces, board 1 also moves by indicated direction 15 from right to left.When running to corresponding and preceding upset breach 18a place, because of the positive Z of being partial to of mah-jong pieces, the center of gravity position is taken advantage of and is crouched on conveyer belt; And unsettled (beyond the dotted line) outside conveyer belt be the light partially mah-jong pieces reverse side F of weight; Can not turn on one's side, see also board 1 residing a position and corresponding Fig. 7 a among Fig. 6, mah-jong pieces continue to lie on one's side on conveyer belt 14 and receive spigot surface 11a, 12a guiding once more; Be transported to inclined thrust surface 13a place; Receive the pushing and pressing of this inclined thrust surface 13a, move forward with driving-belt on the one hand, move to the identification slot direction of a corresponding side on the one hand; The bearing-surface that makes the center of gravity of board fall into conveyer belt 14 produces rollover outward to be changeed, and sees c position and corresponding Fig. 7 b among Fig. 6.So the present invention is organized into the consistent board of board face through the biasing of board center of gravity and the inconsistent board of cooperation trump card face of corresponding switching mechanism, need not the positive and negative that photo electric sensitive element and corresponding electrical circuits are come identifying plate.
