Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic tile washing device for mahjong tiles embedded with permanent magnets.

No. %1kl18ss-180BO7 filed by the present applicant as an automatic tile washing device for mahjong tiles embedded with permanent magnets.
There is an automatic tile washing device for mahjong tiles, but the conventional automatic tile washing device uses a plurality of permanent magnets whose upper surface has a polarity opposite to the polarity of the face of the mahjong tile, which is embedded with permanent magnets with matching polarity. It is fixed to a magnet mounting board, and when washing tiles, the silver magnet attached is placed close to the underside of a mahjong table on which lashes, etc. are pasted on a board made of non-magnetic material, and magnetically applied to the mahjong tiles scattered on the table. Tiles are washed by applying force. Therefore, after the tiles have been washed, the mahjong tiles on the table will not appear unless the magnet mounting board is lowered to a position where no magnetic force is applied to them. In order to lower the magnet mounting board to a point where the magnetic force does not affect the mahjong tiles on the table during play, it is necessary to lower the magnet mounting board by more than 10 m +, and the height of the entire device is high, and the magnet mounting The mechanism for moving the panel up and down is complicated9, and therefore the price is high.

The present invention has been made in view of the above-mentioned drawbacks of the conventional automatic tile washing device for mahjong tiles (hereinafter simply referred to as tiles) in which permanent magnets are embedded with matching polarity.

) To perform the automatic tile washing, a plurality of 0 through holes are made on the bottom of the mahjong table, which is made of non-magnetic material, and a magnetic shielding plate made of ferromagnetic material, such as a round iron plate, is provided, and the tiles are washed. In this case, a permanent magnet whose upper surface has a polarity opposite to that appearing on the face of the tile is placed below the through hole, and the permanent magnet is rotated while applying magnetic force to the tile to wash the tiles. It is an object of the present invention to provide an automatic tile washing device for playing a mahjong game by removing the influence of magnetic force on tiles by displacing a permanent magnet relative to the through hole when tile washing is completed.

First, the basic configuration of the present invention will be explained. Figure 1 (a) shows the state of the tiles before they are washed. 100 is a non-magnetic mahjong table, 101aFi face down tiles, 101b
indicates a tile face up. 10 is a magnetic shielding plate made of a ferromagnetic material manufactured by Teppango. 11 is a permanent magnet, tile 101m
, 101b are mounted on the magnet mounting board 4 with the opposite polarity appearing on the upper surface aligned. The magnetic force of each permanent magnet 11 is shielded by the magnetic shielding plate 10, so that the tiles 101m and 101bK do not act on them and are in the state of being discarded. Then, as shown in the first WA (b), either the magnetic shielding plate 10 or the magnet mounting board 4Iv is rotated, and the permanent magnet 11 is installed in the magnetic shielding plate 10 under the through hole 10aO.
When it appears, its magnetic force is tile 101m, 101b
It becomes a state where it acts on.

When the magnet mounting board 4 and the magnetic shielding plate 10 are integrated into the bale and rotated below the mahjong table 100, the face-down tiles 101b, which receive the magnetic force from an oblique direction, are attracted to the permanent magnets 11, and the face-up tiles 101b and 101b are turned over. The tile is washed. After the tile washing is completed, by changing the relative position of the magnetic shielding plate 10 and the magnet mounting board 4 and shifting the permanent magnet 11 from below the through hole 10a of the magnetic shielding plate, the magnetic force against the tile 101a is transferred to the magnetic shielding plate 10. The tiles are shielded and the tiles can be handled freely.

Next, a second embodiment of the automatic mahjong tile washing device according to the present invention will be described.
This will be explained based on FIG.

1 is a base, and a fixed shaft support 2 is fixed to the base 1. The fixed shaft 3 is fitted into the center hole of the fixed shaft support 2 and fixed with a fixing screw 3a. The magnet mounting board 4 is
A sea leaf is fixed to the seat part No. 4, is rotatably supported on the fixed shaft 3 via a bushing material 4b such as a bearing material, and is placed on the upper end surface of the fixed shaft support 2 via the bushing material 4b. There is. A motor 5 drives a pulley 7 via a belt 6. There are 101 m of tiles on the top of the magnet mounting board 4.
Several exposed permanent magnets 11 are fixed at intervals with the polarity opposite to that appearing on the face of the figure aligned on the upper surface. A ring-shaped member 8 located above the magnet mounting board 4 has a friction plate 9 fixed to its upper surface, into which the fixed shaft 3 is inserted and fixed with a fixing screw 8a.

Numeral 10 is a magnetic shielding plate made of a ferromagnetic material thickened with iron plate.The number of through holes 10 m is the same as that of the permanent magnet 11, and the area of the upper surface of the permanent magnet 11 is slightly larger than the upper surface of the permanent magnet 11. It is provided for. The fixed shaft 3 is inserted into the magnetic shielding plate 10 with a bearing material 10b interposed therebetween, and the magnetic shielding plate 10 is placed on the ring-shaped member 8 with a friction plate 9 interposed therebetween. A plurality of coil springs 12 are stretched between the magnet mounting board 4 and the magnetic shielding plate 10. 4C is an upward protruding piece fixed to the upper peripheral edge of the magnet mounting board 4, 10* is a downward protruding piece provided on the lower surface of the magnetic shielding plate 1G, and the upward protruding piece 4C is a downward protruding piece 10. They are in a positional relationship that allows them to engage. 10 d A large number of casters are fixed to the periphery of the magnetic shielding plate 1G.
It rides on an annular guide 14 that is set up on a base l and fixed to one of several exposed columns 13, and rolls on the annular guide 14 as the magnetic shielding plate lO rotates. In this way, the magnetic shielding plate 10 is prevented from being bent by the downward attractive force of the permanent magnet 11.

Next, we will discuss the effect.

When the motor S is driven, the magnet mounting plate 4 fixed to the sea leaf by the belt 6 rotates 30 times around the fixed shaft, but the magnetic shielding plate 10 remains stationary for a while due to the resistance of the friction plate 9. When the coil spring 12 is stretched and the upward protruding piece 4c of the magnet mounting plate contacts the downward protruding piece 10a of the magnetic shielding plate, the permanent magnet 11 will be located below the through hole 10m. In this state, the magnetic shielding plate lO and the magnet mounting board 4 begin to rotate as one.

Then, the permanent magnet 11 (Di magnetic force tiles on the mahjong wheel 101m
, 101b, tiles are washed in the manner described as the basic configuration of the present invention. Timer 5 is activated by a timer (not shown) that is set in advance when the tile washing is completed.
When stopped, both the magnetic shielding plate 10 and the magnet mounting plate 4 stop rotating, and the magnetic shielding plate is pushed by the tensile force of the magnet mounting plate 4Fi coil spring 12 and moved away from the permanent magnet 11Fi 10m below the through hole. 10 is a good tile that is blocked by 10
1. Magnetic force will no longer be exerted on the magnetic field.

Note that the coil spring 12 is omitted and the motor S is a reversible motor, and the magnet mounting board 4 is moved to a position slightly apart from the downward protruding piece 10c, that is, to the extent that the permanent magnet 11 can be removed from the through hole 10 m below the magnetic shielding plate 10. A downward protruding piece 10 is installed in a position where it can be rotated in the opposite direction (see Figure 3).
After stopping the magnet mounting board 4 and the magnetic shielding plate 1G,
The reversible motor may be stopped after the reversible motor is rotated in the opposite direction so that the upward protruding piece 4c comes into contact with the downward protruding piece 10. Alternatively, instead of the casters 101 and the award guide 14, an anti-friction material of I-retetrafluoro-ethylene may be fixed to the upper surface of the permanent magnet 110 so as to be in sliding contact with the lower surface of the magnetic shielding plate 10. Further, the magnet mounting plate 4 can be driven by gears or other means other than the belt.

As can be understood from the above explanation, the automatic mahjong tile washing device according to the present invention is an automatic mahjong tile washing device in which permanent magnets are embedded with the same polarity. A magnetic shielding plate made of ferromagnetic material with multiple through holes placed close to the underside of the mahjong table, and a magnetic shielding plate made of a ferromagnetic material having a plurality of through holes placed close to the bottom surface of the mahjong table, and a polarity opposite to that appearing on the face of the mahjong tiles placed on the bottom side of the wrinkled magnetic shielding plate. A magnet mounting board on which several permanent magnets are fixed at intervals with the polarity of the upper surface, a relative movement mechanism between the magnet mounting board and a magnetic shielding plate that makes the permanent magnets appear below the through hole, and a through hole. It is similar to a rotating mechanism that rotates the magnet mounting board and the magnetic shielding plate as a unit with the permanent magnet appearing below.

Therefore, since there is no mechanism to move the permanent magnet mounting board up and down, the structure is simple and the height is low, which not only reduces the price, but also saves the power required to move the magnet mounting board up and down.
In addition, there is no need for hand holding time while raising the magnet mounting board.
