The purpose of this utility model be to provide a kind of simple and compact for structure, stable, fault rate is low, reason board speed is fast especially, cheap, adjust point less, installation and maintenance manage the automatic Mah-jongg machine of board in the four sides easily simultaneously.
The technical scheme that realizes the utility model purpose is: the automatic Mah-jongg machine of board is managed at the four sides simultaneously, contain motor and reducing gear, the dish of shuffling, the spring driving lever, the taper pressure ring, the center axle bed, its design feature is to be equipped with the reason board to send the board system on four angles of dish of shuffling, there is the mounting bracket that is fixed as one with mahjong table in this system, the branch axis is housed on it, the middle part of branch axis is equipped with and is shuffled and coils the driven gear of gears engaged, divide the upper end of axis and the below of driven gear that sucker and cam are housed respectively, push rod and torsion spring are contained in the bottom of mounting bracket and can rotate around push rod shaft, the below of sucker is a delivery chute, on the sucker symmetry be provided with two suction magnets, the below of delivery chute porch is equipped with magnetic valve and in the one side reflecting light electric inductor is housed.
The sucker driving lever is equipped with in the back of suction magnet described in the utility model.
Advantage and good effect that the utility model is compared with prior art had are: (one) has four separate reason boards and send the board system, board is inhaled at the four sides simultaneously, reason board speed is fast especially, compare with the cards arranging apparatus structure of single card-inlet, can shorten the reason board time 3/4ths in theory; (2) the reason board send the board system to finish board turning, inhale board, conveying, sign indicating number board, counting a series of actions, thereby make simple and compact for structure, stable, fault rate is low, installation and maintenance are convenient; (3) traditional belt conveying, chain load mode have been abandoned fully, its reason board send the sucker of board system with shortest path mah-jong pieces to be delivered to from the dish of shuffling and waits the board platform, reduced the fault rate of bringing because of the friction conveying, running stores reduce, the adjustment point reduces, the growth in service life; (4) whole mahjong table only is used as power with a gear reduction motor, reliability height, cheap, energy savings.
To and contrast accompanying drawing by embodiment below describes the utility model:
As shown in the figure, present embodiment comprises motor and reducing gear 1, the dish 2 of shuffling, spring driving lever 3, taper pressure ring 4, center axle bed 5, reason board send board system 6.The driving power of this automatic Mah-jongg machine has only a motor and reducing gear 1, be installed in the below of mahjong table, the dish 2 of shuffling that is contained on the center axle bed 5 by gear driven turns clockwise, shuffle the dish the top spring driving lever 3 and taper pressure ring 4 are housed, taper pressure ring 4 makes the board in the middle of the dish sliding outward, and spring driving lever 3 is dialled outward flange to the dish 2 of shuffling with mah-jong pieces.Four separate reason boards are housed on four angles of mahjong table send board system 6, its power comes the dish 2 of shuffling of autorotation, driving four reason boards by gear drive send the driven gear 6-3 of board system to be rotated counterclockwise, as shown in Figure 4, the reason board send the board system to comprise mounting bracket 6-1, divide axis 6-2, driven gear 6-3, sucker 6-4, cam 6-5, push rod 6-6, torsion spring 6-7, push rod shaft 6-8, delivery chute 6-9, suction magnet 6-10, magnetic valve 6-11, reflecting light electric inductor 6-12, sucker driving lever 6-13, mounting bracket 6-1 and mahjong table are fixed as one, in the central authorities of support branch axis 6-2 is housed, divide the middle part dress of axis and the driven gear 6-3 of the dish gears engaged of shuffling, the top dress sucker 6-4 that divides axis, the edge symmetry of sucker be provided with two suction magnet 6-10, sucker driving lever 6-13 is equipped with at the rear portion of suction magnet, be delivery chute 6-9 below the sucker 6-4, magnetic valve 6-11 be housed below its porch and adorn reflecting light electric inductor 6-12 in a side of magnetic valve.On the branch axis of driven gear 6-3 below cam 6-5 is housed.Push rod 6-6 and be contained in torsion spring 6-7 on the push rod and be fixed on the bottom of mounting bracket 6-1 and can rotate around the push rod shaft 6-8 of stiff end.
Operation principle of the present utility model and process are: whole mahjong table is driven by a motor and gear reduction 1, driving shuffle the dish 2 and taper pressure ring 4 on center axle bed 5, turn clockwise, the dish of shuffling that rotates is rotated counterclockwise by gear driven driven gear 6-3, send the board system that power is provided thereby independently manage board to four simultaneously.When driven gear 6-3 rotates, drive cam 6-5 and sucker 6-4 around a minute axis rotation, cam ovalize, cooperating with torsion spring 6-7 during rotation makes push rod 6-6 swing back and forth around push rod shaft 6-8, thereby finish the showdown action, driven gear whenever rotates a circle, twice back and forth of push rod 6-6 swing.When sucker 6-4 rotates, two suction magnet 6-10 that are contained in symmetry on the sucker also rotate thereupon, constantly finish board turning, inhale board, send the action of board, literal mah-jong pieces are down siphoned away immediately by suction magnet (pole orientation is identical with literal board down), up literal or edge-on board, inconsistent because of its pole orientation and suction magnet, when moving to the suction magnet below, promptly overturn, become literal board down.The sucker driving lever 6-13 of suction magnet back is used for the pull over tail end of delivery chute 6-9 of mah-jong pieces, the sidewall of delivery chute 6-9 changes the direction of motion of mah-jong pieces by force, mah-jong pieces and suction magnet are broken away from, under the acting in conjunction of inertia force and sucker driving lever, mah-jong pieces slide to the tail end of delivery chute 6-9 rapidly, this moment, push rod 6-6 just in time began mah-jong pieces to be shifted onto waited on the board platform 7 to waiting the motion of board platform direction.Sucker 6-4 revolution moves a week, just has two mah-jong pieces to be transported to the tail end of delivery chute 6-9, and cam 6-5 also rotates a week, and push rod is just in time swung two cycles, two mah-jong pieces is all pushed to waited the board platform.
Counting control principle of the present utility model is: tally function is mainly realized by reflecting light electric inductor 6-12 that is positioned at delivery chute 6-9 one side and the magnetic valve 6-11 that is positioned at below, delivery chute porch, when the reason board send the board system to start working, valve core of the electromagnetic valve is inhaled into electromagnetic valve coil, delivery chute is unimpeded, mah-jong pieces pass through delivery chute 6-9 under suction magnet 6-10 drives, every mah-jong pieces are through reflecting light electric inductor 6-12 front, the capital produces a pulse at the inductor signal end, provide count signal to counter, when counting reaches setting pier numerical value (as " 17 "), promptly produce control signal Q by counter, control magnetic valve 6-11 ejects spool, stop that mah-jong pieces continue to enter delivery chute, control signal Q controls time board platform 7 lifting motors again and turns over an angle simultaneously, make the height of waiting mah-jong pieces of board platform sinking, wait for the arrival of another layer mah-jong pieces; Afterwards, counter O reset, magnetic valve 6-11 sucks spool once more, allow mah-jong pieces continue by delivery chute, when counting reached setting pier numerical value again, the control magnetic valve ejected spool once more, stop that mah-jong pieces continue to enter delivery chute, like this, waiting has just had quantity to be the two-layer mah-jong pieces of setting pier numerical value on the board platform, and a foliation board is finished.
