Abstract

PURPOSE:To obtain a mah-jongg game machine using only one group of mah-jongg tiles and having a small size play table, by arranging, in one plane, first to fourth elevators each for carrying thereon one-fourth of the mah-jongg tiles which are pushed out one after another so as to arrange them crosswise, and mechanisms disposed between the elevators, for perpendicularly feeding the mah-jongg tiles so as to turn and move them. CONSTITUTION:Mechanisms 60 for perpendicularly feeding mah-jongg tiles are arranged each between a second elevator 52 and a third elevator 53, and between third elevator 53 and a fourth elevator 54. The mah-jongg tiles are set with their letter side surfaces facing up and down while they are agitated, and are aligned by a long and short side confirming mechanism 20 with their short sides facing front and rear. Further, they are set with their letter side surfaces being directed downward by a front and rear side aligning mechanism 30, and then are stack one upon another in two stages by a two-stage tile stacking mechanism 40 before they are aligned on the elevators 51 through 54. When the foremost tile reaches an all tile confirming mechanism 70, the first to fourth elevators 51 through 54 is raised up, and finally, the stacking of the tiles on the upper plate 3 or a table 4 is completed while tile charging ports 3a are blocked, thereby it is possible to start the game.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a mahjong game machine.

(Prior art) With the development and diversification of play equipment, mahjong pie (1
! A mahjong game machine called an automatic Martian table has become popular, which automatically stirs the pieces (hereinafter referred to as ``pies'') and stacks them in the so-called east, south, south, and north directions for the convenience of the player.

The above-mentioned mahjong game machine generally requires two pie sets, and during the tabletop game, the remaining pie set is stirred in the car and piled up, and the new and old pie sets are replaced by a push button signal. This is a replacement method.

(Invention or problem to be solved) Therefore, two pie sets are required even though only one is used at all times, and the height inside the car increases, so the Martian table cannot be large. I have no choice but to.

Therefore, there is a need for a mahjong game machine that requires only one set of mahjong pies and a small table size.

(Means for Solving the Problems) In order to meet the above requirements, the present invention provides a pie stirring mechanism, a long and short side confirmation mechanism, a front and back side alignment mechanism, and a pie pie with two layers! A mahjong game machine is constructed by arranging an i-reading mechanism, first to fourth elevators, and a pie-perpendicular feeding mechanism in a plane.

(Function) The bi-stirring mechanism mixes the pie and turns the letter face up/down, the long and short side checking mechanism turns the pie with the short side facing the front, and the front and back embossing mechanism turns the letter face downward. A two-tier pie stacking mechanism is used to stack two tiers of pies, one above the other, and then push out the pies in tiers one by one in a rolling manner and place them on the first to fourth elevators in a horizontal row.Then, the elevators are raised to stack the pies in a specified number of pies. Place it on the table.

(Example) Embodiments of the present invention will be described below based on the accompanying drawings.

FIG. 1 is a plan view of the internal structure of the mahjong game machine, with the top plate removed.

The mahjong game 411 has a pie stirring mechanism 10 in the center of a rectangular machine frame 2, and a long and short side checking mechanism 2 extending from this mechanism.
0, the front and back alignment mechanism 30, the pie two-tier stacking mechanism 40, and the first to
It consists of fourth elevators 51-54.

Each of the above constituent mechanisms will be explained in detail.

FIG. 2 is a plan view of the pie stirring mechanism, and FIG. 3 is a cross-sectional view of the same. The rotor 11 has a conical upper surface and a guide frame 12 surrounding the rotor 11. Moreover, the center of the rotor 11 is eccentric by α from the center of the pie inlet 3a, and the rotor 11 is reversely rotated by 115 θ every time it rotates by a certain angle θ.

The inserted pie P falls due to the difference between the rotation of the rotor and its own inertia (in the direction of the front and back of the drawing, arrow ■), and also due to the relative horizontal movement between the eccentric rotor 11 and the input port 3a with a fixed position value, the pie P
falls in the direction of the arrow ■, and in the end, no matter which direction the pie P is thrown in, the widest character surface is taken to be the top and bottom sides. The pie P is mixed appropriately by the rotation of the rotor 11.

Therefore, the pie stirring mechanism 10 stirs the group of pies put in, aligns the letters on the top and bottom, and uses the centrifugal rotational force to cause the pies to rest on the guide frame 12 and send them to the next mechanism.

FIG. 4 is an enlarged view of the long and short side checking mechanism of the pie. The long and short side checking mechanism 20 is constructed by partially cutting off the outlet of the guide frame 12 and locking it with a pin so that it can swing freely. It consists of a flapper 21 which is installed internally so as to exert a spring force in the direction of the arrow ■, and a pair of cage rollers 22, 22 arranged on the left and right sides of the entrance of the next first belt conveyor Bl. There are driving rubber rollers that rotate to the left in the figure, and are arranged at intervals wider than the short sides of the pie and narrower than the long sides.

When the pie P pushed out from the pie agitation mechanism 10 faces the long side P1 or the gate roller 22, 22, further entry is prevented. However, since the gate rollers 22, 22 are rotating to the left, the pie P rotates to the right, and when it has turned about 90 degrees, the gate roller 2 is rotated with the short side P2 in front.
It passes between 2.22 and 2.22. During this time, the flapper 21
It acts to suppress the pie P while applying an appropriate urging force so that it does not jump out of the guide frame 12.

FIG. 5 is a side sectional view of the front and back alignment mechanism. The front and back alignment mechanism 30 includes a cylinder 33 that is rotatably supported laterally within a cylindrical outer frame 32 fixed to a base plate 31, and an outlet of this cylinder. 33a, and a magnetic roller 34 disposed so as to cross the outside of the magnet roller 33a. Note that the diameter of the cylinder 33 is slightly larger than that of the Marchandby P.

In addition, mahjong pie P is on the character surface P3 as shown in the figure.
An iron piece P4 is embedded inside the bi near to.

6(a) to 6(C) are operational views of FIG. 5, and in FIG. 6(a), the pie P conveyed from left to right by the first belt conveyor B1 is transferred to the cylinder 33. It is assumed that the pie P at this time is on the character surface P3 or facing upward.

Then, the lower front surface of the pie P comes into contact with the magnet roll 34. The pie P is blocked and locked by the magnet roll 34.

During this time, the cylinder 33 rotates in the direction of the arrow, and as a result, the sixth
As shown in Figure (b), the pie P is inverted so that the character face P3 faces downward.

Then, the iron piece P4 near the character surface P3 is moved to the magnetic roll 34.
Because the object is close to the object, it is attracted by the magnet roll 34.

Therefore, as shown in FIG. 6(c), the pie P is guided by the magnet roll 34 and transferred from the cylinder 33 to the second belt conveyor B2 with the letter face P3 facing downward.

If the next pie P' is conveyed with the letter side P'3 facing downward, Figure 6(a) will be omitted and Figure 6(b) will be shown immediately.
It is clear that the belts are laterally moved from the first belt conveyor Bl to the second belt conveyor B2 in the order shown in (c).

Therefore, the first front and back die alignment mechanism 30 works in cooperation with the cylinder 33 and the magnet roll 34 to align the letter faces P3 of the pie P downward.

FIG. 7 shows a pie stacking mechanism in two tiers, and FIG. 8 shows a cross section taken along the line ■-■ in the same figure. It consists of a by-floor 44 that is sufficiently lower than the belt conveyor B2.

As shown in FIG. 8, when the pie P moved by the second belt conveyor B2 passes over the magnetic roller 41, it is guided by the rotation of the roller and is first placed on the pie bed 44, where it is placed on the pie bed P5 on the lower stage. Become.

The next pie P is placed on top of the lower pie P5, and by pushing out the upper pie P6 or the upper pie detection claw 42, the pusher 43 moves one pie to the right.

Through the mutual reciprocation of the detection claw 42 and the pusher 43, the upper and lower two stacked pie P6. P5 are lined up one after another in the first elevator 51 in a so-called tokoroten style. In addition,
The first to fourth elevators 51 to 54 are horizontally elongated belt conveyors, and move freely due to external force, so there is no fear of wearing out the letter face P3 of the pie P.

In this example, one end of the first elevator 51 also serves as the pie bed 44.

Figure 9 shows the right angle pie feeding mechanism, and the first elevator 5
A right-angled pie feeding mechanism 60 disposed at the corner of the exit of the first elevator 52 and the entrance of the second elevator 52 has an upright rubber roller 61.
and a rubber heald 62 with an upright belt surface.
The pie P pushed out from the exit of the first elevator 51 is narrowed by the rubber roller 61 and the soft rubber belt 62, and since the speed of the rubber heald 62 is high, it turns counterclockwise, resulting in the population of the second elevator 52.

This right angle pie feeding mechanism 60 is provided between the second elevator 52 and the third elevator 53 and between the third elevator 53 and the fourth elevator.
It is also interposed between the elevator 54 and the elevator 54.

Therefore, the pie P, which is sent one after another by the pusher 43 described in FIG. 7, moves forward to the fourth elevator 54.

The leading pie P is detected by the all-buy confirmation mechanism 70 provided at the lower end of the fourth elevator 54 shown in FIG. This full pie confirmation mechanism 70 is suitably one that detects the iron piece P4 buried in the pie P, a mechanical limit switch that contacts the pie, or a non-contact optical limit switch.

The operation of the mahjong game machine having the above configuration will be described below.

When the player presses a push button on the operation panel, the lid (not shown) of the bike slot 3a on the top board 3 opens.
The stirring rotor 11 rotates to the left.

The player throws the pie group on the top plate 3 into the pie slot 3a.

While being stirred, the pie P is arranged so that the letter side is the top and bottom sides, and the short side or the front and back sides are aligned by the long and short side confirmation mechanism 20,
The front and back alignment mechanism 30 allows the characters to face downward, and the two-tier pie picking mechanism 40 stacks the letters in two layers, one above the other, and then arranges them on the first to fourth elevators 51 to 54.

When the first pie or all pie confirmation mechanism 70 is reached, the first to fourth
The elevators 51 to 54 go up, and as a result, four piles of pies are stacked on the top plate 3, that is, on the table, and during this time, the byte slot 3a is closed with the lid, and the game can begin.

(Effects of the Invention) As described above, the present invention arranges the main constituent elements on a plane, which makes the height of the mahjong game machine much smaller, and only one set of mahjong pies is required, making effective use of the pies. As a result, the game machine can be made smaller and its price can be lowered.
