Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention provides a tabletop setting mechanism for mahjong tiles, and more specifically, a mechanism for setting tiles on the tabletop, which allows selection of tiles set on the tabletop for either normal bid construction or tile arrangement. The present invention relates to a tabletop setting mechanism.

[Conventional technology]

In recent years, mahjong tables have been increasingly mechanized to automatically perform everything from washing tiles to arranging them on the table.

Traditionally, mahjong tables that can automatically arrange the tiles have been proposed to be roughly divided into two types: those that build the cards on the table from the tiles being washed, and those that automatically combine the cards and the dealt tiles after washing the tiles. ing.

[Problem that the invention seeks to solve]

Each mahjong table as mentioned above has only a single mechanism according to its structure.

By the way, when playing mahjong, each person has their own preferences. For example, some people may be fine with the tiles being dealt automatically, while others may find it more interesting if each person takes the tiles themselves from the outset. There is a problem in that in order to suit each player's preferences, it is necessary to prepare a mahjong table with each mechanism.

This invention was made in order to solve the above-mentioned problems, and it is possible to freely select a setting in which only a single mechanism is used to construct a ticket arrangement, or a setting in which this is combined with a tile arrangement. It is an object of the present invention to provide a tabletop setting mechanism for mahjong tiles that allows for smooth sending out of tiles.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention provides a mahjong tile first taxiway which is arranged in two stages (upper and lower), in which the receiving of mahjong tiles can be varied up and down, and a third taxiway with one stage in the second taxiway. are arranged in a plane and their tip sides are reversed upward in an arc shape; a tile feeding mechanism that supplies mahjong tiles to a position corresponding to the third taxiway taxiway;
a tile feeding selection mechanism which is also arranged at the tile receiving side end of the guideway group and can limit the tile feeding position by the tile feeding mechanism to only the positions corresponding to the first and second guideways;
a tile extrusion mechanism arranged to run along the guideway group and capable of simultaneously extruding mahjong tiles in each guideway;
a tile stacking mechanism disposed above the tip of the guideway group, which moves the mahjong tiles of the first guideway pushed out when activated and stacks them laterally on top of the mahjong tiles of the third guideway; The group of mahjong tile guide paths includes a receiving plate that is placed at a position in front of the tip and receives the pushed out mahjong tiles and lifts them onto the top plate of the mahjong table. One side of the taxiway is open, and the third taxiway is arranged at the middle height position of the first taxiway on the opening side, so that the mahjong tiles in each taxiway come into contact and guide each other. It was formed.

[Effect]

In the case where only bidding is to be set, the movable floor serving as the floor surface of the second guideway is pulled up to the raised position, and the tile stacking mechanism waits at the forward position.

When tiles are supplied from the tile feeding mechanism to the receiving end of the first guideway and the third guideway, the tile pushing mechanism moves back and forth a certain stroke from the leaving position to feed the tiles into both the above guideways, and this operation is repeated 17 times to sequentially feed the tiles, and when 17 tiles are lined up in each guideway, the tile pushing mechanism moves forward continuously and pushes the tiles forward.

The tiles on the second side that are pushed out from the tips of the first and third guideways are moved down a little by the tiles in the third guideway, and the tiles in the first guideway are moved laterally by the guide edge of the tile stacking mechanism, moving up and down. It is extruded onto the table in two stacks.

In the case of tile distribution combination setting, the movable floor of the second taxiway is lowered, the tile stacking mechanism is in the leaving position, and the two tiles supplied to the receiving end of the taxiway group are stacked on the second taxiway and the third taxiway. When the tiles are sent into the taxiway and the number of tiles corresponding to the first row of tiles has been sent, the movable floor rises and at the same time the tile feeding selection mechanism moves forward.
A predetermined number of tiles are sent into the first taxiway while the supply of tiles is restricted to the first taxiway, and after that, the selection mechanism leaves work,
Send the tiles to the first and third taxiways, and when the number of tiles on the third taxiway reaches 13, push out the tiles in all the taxiways and move the tiles to the first taxiway.
The tiles on the second taxiway are stacked vertically to form a deck, and the tiles on the third taxiway are arranged on the table as dealt tiles.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in the figure, the top plate 2 of the mahjong table 1 has a length that accommodates the 17-width wall of tiles A, and a long opening 3 through which the tiles lined up on two sides in the longitudinal direction can pass, parallel to each side of the table. These openings 3 can be opened and closed by a single piece receiving plate 4 that swings up and down about one end pivoted on the top plate 2 in the longitudinal direction. A setting mechanism 11 is arranged.

The tabletop setting mechanism 11 includes a tile guiding path group 14 provided on one side of a side wall 13 erected on a base 12, a tile feeding mechanism 15 and a tile feeding mechanism 15 arranged at the tile receiving side end of this guiding path group 14. The selection mechanism 16 and the tiles A along the taxiway group 14
It is composed of a tile extrusion mechanism 17 for extruding tiles, and a tile stacking mechanism 18 disposed at the extrusion side tip of the guide path group 14.

The tile guideway group 14 includes a first guideway 14a and a first guideway 14a.
It is formed by a combination of a second guideway 14b overlapping the guideway 14a and a third guideway 14C arranged along the side surface opposite to the side wall 13 of both the first and second guideways 14a and 14b, Each guideway 14a, 14b, 14e has a cross-sectional shape whose width accommodates the longitudinal direction of tile A (7), and as shown in FIG. The side surface of the third taxiway 14C is closed, and the third taxiway 14C has a height that is located in the middle of the first taxiway 14a. The end faces of the tiles A are in contact with each other to provide stability during movement.

As shown in FIG. 1, the guideway group 14 slopes gently forward and upward in a straight line from the tile-receiving end, then its extension is reversed upward into an arc of about 180', and the first and second guideways are connected at the tip. The taxiways 14a and 14b are reversed vertically, and the third taxiway 14
The tip end floor surface of C is bent downward so that it is at the same height as the tip end floor surface of the second guideway 14b, and the receiving plate 4 is in a downwardly inclined position, and the floor surface of the second and third guideways 14b and 14C is bent downward. It has an extension shape to the surface and is designed to receive tiles A that are pushed out from both slopes.

The floor surface of the lower straight portion of the second guideway 14b becomes a movable floor 20 that moves up and down around a pivot 19 on the tip side, and is moved up and down by a driver 21 such as a solenoid attached to the side wall 13. 20 is in the lowered position as shown in FIG. Allow tile A to enter.

This second guiding path 14b is used only when setting a combination of tiles to be dealt, and when setting only a ticket issue, the movable floor 20 is held in a raised position to prevent the tile A from entering.

As shown in FIGS. 4, 5, and 6, the tile feeding mechanism 15 that supplies tiles into each of the guide paths 14a, 14b, and 14C is configured to feed tiles A discharged from a feeder (not shown).
Side walls 23 are erected on both sides of the pedestal 22 that receives the pedestal 22.
The tile receiving part is provided with a stepped part 24 that partially receives the lower end of the falling tile and allows the tile A to fall to the front position with the surface facing upward. Extrusion means 2 for pushing the fallen tile A forward with a certain stroke
5 is provided.

A stepped portion 26 is also provided on the cone end side of the pedestal 22, on which the rear tile is engaged with two extruded tiles lined up in the longitudinal direction. A tile receiving plate 28 is provided at the tip of the movable plate 27 along the side surface of the movable plate 27, and a spring 2S is applied to the movable plate 27 so that the movable plate 27 always returns to the rear piece.
When the user pushes the movable plate 27 forward via the tile receiving plate 28, the cam 30 provided on the side of the movable plate 27 activates the limit switch LS.
It is supposed to be pressed.

A blocking piece 31 is provided at the base end of the movable plate 27 so as to protrude directly above the stepped portion 24 when the movable plate 27 moves forward and prevents the next tile from falling onto the pedestal 22.

As shown in FIG. 5, the tile feeding selection mechanism 16 has a restriction plate 32 disposed behind the receiving end of the guide path group 14 so as to be movable forward and backward along a guide 33. 32 is connected to a driving device 35 such as a solenoid via a swing link 34, and a spring 36 biases the restriction plate 32 with elasticity to return to the leaving position. It has a width approximately equal to the dimensions.

When the head 32a of the restriction plate 32 moves forward, the head 32a
When it protrudes upward and is released from the guide 33, it becomes swingable in the width direction, and when pushed by a tile pushed out onto the pedestal 22, it moves in the pushing direction and pushes the tile receiving plate 28. 3 taxiway 14C is blocked and tiles are supplied to the first or second taxiway 1.
4a and 14b.

As shown in FIG. 1, the tile pushing mechanism 17 hooks an endless belt 40 to run along the inside of the guideway group 14 across pulleys 37, 38, and 39 arranged at both ends and the upper part of the side wall 13. The pulley 37 is driven by a motor 41 capable of forward and reverse rotation, and a tile pushing member 42 is attached to the outside of the belt 40.
Three push arms 4 moving along inside 4a, 14b, 14C
2a42b, 42C.

The tile pushing member 42 is connected to the tile feeding selection mechanism 16 as shown in FIG.
The leaving position facing directly above is set by the first detection piece 43 attached to the belt 40 and the limit switch LS2,
When sending out tiles, the belt 40 moves counterclockwise to the motor 4 in FIG.
1.

There are two ways of driving the mo and - e 41: tile feeding and tile pushing out, and in tile feeding, the tile pushing member 42 reciprocates while entering the receiving side end of the guide path group 14 from the leaving position. This reciprocating motion can be set by detecting the limit switch LS3 and the second detection piece 44 or electrically switching the energization to the motor 41.

Also, when pushing out tiles, switch LS for feeding tiles,
does not act, and the first detection piece 43 and limit switch LS detect the stroke in which the tile pushing member 42 continuously moves to the tip of the guideway group 14, and the tile pushing member 42 is moved to the opposite position. It is designed to be

The tile stacking mechanism 18
As shown in the figure, a plate 45 with a cross-section shaped like a slit is disposed directly above the tip of the guideway group 14 so as to be movable in the tile extrusion direction, and a forward movement is provided to this plate 45 via a link mechanism 46. The plate 45 is formed by a driver 47 such as a solenoid that applies the force, and a spring 48 that returns the plate 45 to the leaving position. An inclined edge 45a is provided for laterally moving the tile A pushed out from the second guide path 14b and stacking it on top of the tile A pushed out from the third guide path 14C.

When the plate 45 is in the leaving position shown in the solid line in FIG. 3 or in FIG.
does not act, and the tiles push up the plate 45 and move straight.

Further, when the plate 45 moves to the forward position, it becomes horizontal as shown by the dashed line in FIG. 3 and in FIG. 12, and the inclined edge 45a
protrudes from the second guide path 14I) at an intermediate height position to the tile pushed out, and as shown in FIG. 10, the tile A of the second guide path 14b
will move horizontally.

Note that the side wall 13 at the tip of the guideway group 14 is provided with a horizontally elongated hole 4S on the side of the first guideway 14a.
3 is attached with a tile pushing arm 51 which can move freely into and out of the first guiding path 14a from the horizontally elongated hole 4S and is constantly biased with protruding elasticity by a spring 50, and pushes the pushed out tile A into the first guiding path 14a as shown in FIG. 3 to the side plate side of the guide path 14C, and the tiles A pushed out onto the receiving plate 4 are aligned and moved along the side plate.

Figures 17 to 19 show the state of the tiles in a normal four-player game, Figures 15 and 17 show the construction of only the deck, and Figures 16, 18, and Figure 19 shows the tile set method.

First, the setting method for placing only bids is to stack 17 tiles A on top and bottom in two tiers and arrange them on all sides on the top plate 2, using the first and third guideways 14a and 14C. As shown in FIG. 1, a limit switch LSs is placed in one of the guideways to detect when 17 tiles have been sent.

Next, in the tile set method, the 13 tiles are arranged in all directions on the top board 2, so the remaining tiles for bidding cannot be divided into four equal parts. On the side, 10 tiles each are stacked in two tiers on the top and bottom, and the bids are placed as cents, and on the remaining two sides, 11 tiles each are stacked on the top and bottom in two tiers, and the bids are placed.

The tile set method is based on each of the first to third taxiways 14a, 1
By using 4b and 14C and selecting the supply to each guideway, it is possible to set the deck and the dealt tiles at the same time.

FIG. 18 shows the tile feeding process when 10 tiles are stacked in two stacks, and FIG. 19 shows the tile feeding process when 11 tiles are stacked in two stacks.

In FIG. 18a, first, ten tiles are sent into the second taxiway 14b and the third taxiway 14C, and when these are detected by the limit switch LS in FIG. Seven tiles are sent in as shown in Figure 18, and this is detected by the limit switch LSy.

After that, feed three tiles each into the first taxiway 14a and the third taxiway 14C as shown in Fig. 18C, and switch the limit switch L.
If S is detected, the supply of tiles is completed.

In addition, as shown in Figures 19a to 19C, when placing 11 tiles in two rows, the limit switch LS is set to the 11-tile detection position, and the limit switch LS11 on the first taxiway is set to the position of detecting 11 tiles. It is only necessary to arrange the tiles at the position where nine tiles are detected so that a set of 11 tiles stacked in two stacks and a set of 13 tiles placed can be obtained.

In addition, each of the limit switches and drive machines mentioned above are installed at appropriate positions on the mahjong table, and are used only for cents for placing bids and for tile distribution.)
It is electrically connected to the changeover selection switch, and operates automatically according to the conditions set by this switch.

The setting device of the present invention has the above-mentioned configuration, and its operation will be explained next.

When the changeover switch for setting only the bids is set to the bid only side, the drive machine 21 is energized and the movable floor 20 is raised, and the drive machine 47 is energized to move the tile stacking mechanism 18
advances to the forward position, and the limit switch L for the 17-sheet side ratio
S can be detected, and the tile extrusion mechanism 17 and selection mechanism 16
remains absent from work.

The tiles A that have fallen from the feeder are placed on the pedestal 22 by the action of the stepped portion 24.
The pushing means 25 moves forward and backward each time the tile A falls, and the tile A is placed on the pedestal 2 as shown in Fig. 6.
Push the tip of 2 and when the two tiles are lined up as shown in the figure, the limit switch LS is activated.

Then, the motor 41 starts rotating in the normal direction, causing the belt 40 to travel counterclockwise in FIG.

When the tile is pulled out from the pedestal 22, the limit switch 7chi LSa
reverses the motor 41, and when the pushing member 42 returns to the leaving position, the motor 41 is stopped by the limit switch LSz,
The above operation is repeated every time two tiles are supplied onto the pedestal 22, and when 17 tiles are lined up in the first and third guideways 14a and 14C by sequential feeding, the limit switch LSs is activated.
detects this and motor 41 stops. When the setting machines on all four sides are in the same state, the motor 41 is started by inputting the start signal.
rotates in the forward direction, and the extrusion member 42 simultaneously extrudes the tiles on the two sides, and the tile A is reversed during movement so that its surface faces downward, and is extruded from the tips of the first and third guiding paths 14a and 14C. When the tile that comes out from the first guideway 14a is the 10th tile
As shown in the figure, the tiles are pushed in the horizontal direction by the horizontal stacking mechanism 18, and the tiles are stacked vertically and pushed onto the receiving plate 4, which is descending.

When the limit switch LS detects the completion of extrusion, the motor 41 rotates in the reverse direction, the extrusion member 42 returns to the leaving position, the receiving plate 4 rises, and the stack of cards is placed on all four sides of the top plate 2 as shown in FIG. The settings will be completed.

When setting the allocated tiles in combination, if the changeover selection switch is set to the tile setting side, the drives 4!121 and 47 are not energized, the movable floor 20 is in the lowered position, and the stacking mechanism 18 is in the inactive position. After leaving work, the driver 35 of the selection mechanism 16 becomes ready for operation.

When the two tiles A are pushed out onto the pedestal 22, the motor 41 rotates in forward and reverse directions by the operation of the limit switches LSI and L S y to push out the two tiles at the same time.

At this time, since the movable floor 20 is in a downwardly inclined position, the pushed out tile A is sent into the second guideway 14b and the third guideway 14C, and 10 or 11 tiles line up and limit it. When the switch LS is detected, the drive [21] is energized and the movable floor 20 is pulled up, and the tiles A on this movable floor 20 are held between the ceiling plate of the second guideway 141). be done.

At the same time, the head 32a of the selection mechanism 16
As shown in FIG. 7, it protrudes onto the pedestal 22.

Therefore, the motor 41 rotates forward and reverse at the stop switch LS, which pushes out one tile A onto the pedestal 22, and the tile is supplied only to the first guiding path 14a.

When seven or nine tiles are supplied into the first guideway 142 and detected by the limit switch LSt, the driver 35
The power is cut off, and the head 32a of the selection mechanism 16 moves to the pedestal 2.
2, two tiles are lined up on the pedestal 22 again, and they are pushed out at the same time, and three or two tiles are supplied to the first and third guiding paths 14a and 14C. Then, the number of tiles in the third guideway 14C becomes 13 in total, resulting in a cent state as shown in FIG. 18C or FIG. 19C.

When the limit switch LSs detects 13 tiles, the power to the drive machine 21 is cut off and the movable floor 20 moves to the first guideway 14.
It is placed on tile A in the second guideway 14b.
is released.

In response to the start signal, the motor 41 rotates continuously in the forward direction.
The tiles A in each guideway 14a, 14b, and 14C are simultaneously pushed out, and after the tiles in the three rows are reversed at the tip of the guideway, the tiles in the first guideway 14a overlap with the tiles in the second guideway 14b, and the tiles in the first guideway 14a overlap. The tiles in the third guideway 14C are pushed out as they are and are placed on the single receiving plate 4.

Therefore, the tiles that overlap in two rows above and below are bids, and -5 rows 1
The three tiles become the dealt tiles and are arranged on the table as shown in Figure 16.

〔effect〕

As described above, according to the present invention, a set that only deals tiles by arranging the tiles on the wall of 17@, and a set that deals tiles in combination with placing tiles, can be freely selected by switching the switch, and people who enjoy mahjong can This allows users to set tiles according to their preferences using a single mechanism.

In addition, when placing tiles, the deck and the dealt tiles are pushed out in contact with each other so that they guide each other, so the posture of the tiles during the pushing process is stable, and the receiving plate installed on the top of the mahjong table is This can be received with a single-piece structure, reducing the amount of opening of the receiving plate when only bidding is set, and reducing the risk of objects other than tiles falling into the car.
