Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is an automatic device that can align the orientation of the mahjong tiles at the same time as they are taken out from the tile mixing device, and that can align the tiles easily and quickly. Turn it into a mahjong machine.

[Conventional technology]

For example, as disclosed in Japanese Utility Model Application Publication No. 53-23368, a continuous outer surface fixed to the lower part of a rotating disk with a permanent magnet fixed to the lower surface is used as a tile takeout tool for guiding mahjong tiles from a tile mixing device to a takeout and alignment device. It has been proposed to control the posture of mahjong tiles by providing a guide plate having a guide plate so that the mahjong tiles come into contact with the outer surface of the guide plate.

[Problem that the invention seeks to solve]

However, in this device, the rectangular mahjong tiles are attracted to the permanent magnet regardless of their orientation.

Therefore, although the mahjong tiles are guided by the guide plate, the mahjong tiles can come into contact with the guide plate with either the side or the end face, and the mahjong tiles are taken out with their vertical and horizontal orientations being uneven. There is a problem that the orientation must be aligned again, which complicates the device and takes time to complete the alignment.

The present invention is based on the provision of a hook part on the guide piece that can change the orientation of the mahjong table that is guided by touching the edge of the mahjong tiles, so that the direction of the mahjong table can be aligned at the same time as the mahjong table is taken out, and the tiles can be aligned. The purpose of this invention is to provide an automatic mahjong device that can shorten playback time.

The guide piece 19 has an intermediate portion 19B connected to the front portion 19A extending from the peripheral wall 5, and the rotating body 17 is connected to the intermediate portion 19B.
A guide surface 18 is provided below the magnet body 19 and formed approximately concentrically with the rotating body 17. Note that the guide piece 19 is
9C is along one side end of the conveyor 7.
Extends upstream.

Further, the guide piece 19 is fixed to a support plate 62 extending horizontally from the peripheral wall 5 via a separating piece.

Therefore, the rotating body 17 is placed above the front part 19A of the guide piece 19, and selects the mahjong tiles 2 whose S poles face upwards from among the mahjong tiles 2 . The mahjong tiles 2 are attracted by the second magnetic body 14 and taken out from the mixed tile arrangement 53, and the mahjong tiles 2 attracted by the rotating body 17 are transferred while the side surface 15 or end surface 16 is pressed against the guide surface 18.

Further, the guide piece 19 is provided with the hook portion 20 on the guide surface 18 of the intermediate portion 19B thereof.

The hook part 20 is! As shown in Figure '87, in this embodiment, a short surface 20A is formed by cutting the guide surface 18 and is cut in the radial r direction.The cut surface 18A extends forward from the lower end and has a front end connected to the guide surface 18. form.

The length of the cut surface 18A is determined to be less than 1/2 of the length of the side surface 15 of the mahjong tile 2 and more than 1/2 of the length H of the end surface 16. Note that the tip end P of the hook portion 20 is set to have approximately the same height as the guide surface 18 or a slight height difference therebetween.

The hook portion 20 has a side surface 15 in contact with the guide surface 18 to allow the guided mahjong tile 2 to pass through, and an end surface 16 in contact with the guide surface 18 to allow the guided mahjong tile 2 to pass through the end surface 16.
By colliding the tip and the current 20A, mahjong tile 2
can be turned and turned by 90° while being attracted to the second magnetic body 14. In this manner, on the downstream side of the hook portion 20, all the mahjong tiles 2 attracted to the rotating body 17 are guided with the side surfaces 15 in contact with the guide surface 18, and are aligned vertically.

The conveyor 7 has belt pulleys 71 arranged at the front and rear.

The wall tile alignment section 27 and the hand tile alignment section 28 are arranged on the side surface 15 of the mahjong tiles 2.
Mahjong tiles 2 with a width approximately equal to the length and a predetermined number of tiles
A horizontally long rectangular wall tile aligning board 81 and a hand tile aligning board 82 are provided, each having a length dimension that allows the tiles to be aligned horizontally. The rear ends of the wall tile and hand tile arrangement plates 81 and 82 both extend to the side ends of the conveyor 7.

The extrusion tool 9 includes a first extrusion section 105 that extrudes the mahjong tiles 2 sideways toward the wall tile alignment section 27, and a hand tile alignment section 2.
The mahjong tiles 2 can be aligned with the wall tiles 2A and the hand tiles 2B by the extrusion.

A detector S provided at the front end of the wall tile aligning section detects the completion of the alignment, and the detection output causes the tile takeout tool 6 and the conveyor 7 to move backwards, thereby removing the excess tile on the excess conveyor 7. The mahjong tile 2 can be returned to the mixed tile set 53.

[Effect]

However, after the mahjong game was over, the slot 2 of the table board 23 was opened.
The mahjong tiles 2 thrown in from 5 are placed on the rotating inner rotating board 1.
They are stacked on top of each other and stored.

In addition, since the inner rotation jFi, 11 has a gentle slope, a large amount of mahjong tiles 2 temporarily thrown in from the mahjong table 4 can be accommodated and mixed on the inner rotation plate 11, and the inner rotation plate 11 can be rotated at high speed. The mahjong tiles 2, - are gradually moved in the outer circumferential direction by the centrifugal force, and are transferred to the outer rotary plate 12 in appropriate amounts. Furthermore, the mahjong tiles 2 on the outer rotary plate 12 reduce their speed and rotate slowly along the peripheral wall 5. Outer rotating plate 12
Among the mahjong tiles 2--, which rotate in various postures, the mahjong tiles 2 whose backs face downward are reversed upward by the magnetic force while passing over the magnet body 42. Furthermore, the mahjong tiles 2 with the side surfaces 15 and end surfaces 16 facing upward are shown in FIGS. 13(a) and (b).
As shown in FIG. 2, the tiles are brought down by the projections 44 of the outer rotating plate 12 and the rotating body 17 of the tile takeout tool 6, and are turned upward by the magnetic force of the magnets 44.

In this way, all of the mahjong tiles 2 on the second rotating body 13 are aligned with their backs facing up while they rotate.

Also, as the mahjong tiles 2 pass under the rotating body 17, the second magnetic body 14 attracts the mahjong tiles 2 with the back side upward and takes them out from the tile mixing device 3, and at the same time, the mahjong tiles 2 are attached to the guide piece. 1
It is transferred while being guided by the guide surface 18 of 9. The hook portion 20 of the guide piece 19 allows the mahjong tile 2 guided with the side surface 15 in contact with the guide surface 18 to pass through, and also south of the mahjong tile 2 guided with the end surface 16 in contact with the guide surface 18 . Turn it 90 degrees. Therefore, by passing through the hook portion 20, the mahjong tiles 2 are all oriented vertically and are transferred to the conveyor 7 in a unified posture.

The mahjong tiles 2 on the conveyor 7 are pushed out by the pusher 9 to the alignment and lifting device u10, and the mahjong tiles 2 are arranged in a row on the alignment and lifting device 10 together with the wall tiles 2A and the hand tiles 2B.

The completion of the arrangement is detected by the detector S, and the conveyor 7 and the rotating body 17 are moved backwards (the mahjong tiles 2 remaining on the transfer conveyor 7 can be returned to the tile mixing device 3.
The mahjong tiles 2 returned to 2i 3 are taken out by the tile takeout tool 6 whose rotating body 17 continues to rotate in the forward direction without completing the tile alignment, and are transferred to the alignment and lifting device 10. The surplus mahjong tiles 2 that have been aligned in this manner are quickly returned and fed to other alignment and lifting devices 10 that have not yet been aligned, thereby completing the alignment of the gold tiles in a stone's throw.

〔Effect of the invention〕

As mentioned above, the automatic mahjong device has a first magnetic material embedded in the rectangular mahjong tiles, and the mahjong tiles are placed on the guide surface of the guide piece that guides the mahjong tiles that are attracted to the second magnetic material of the rotating body. Because we have a hook that allows you to align the orientation, you can simultaneously take out the mahjong tiles.
The orientation of the tiles can be aligned vertically, reducing the time required to take out tiles and reducing game interruption time. Further, unlike conventional devices, separate installation of direction adjustment and odor can be omitted, the structure of the device can be simplified, the cost can be reduced, and accidents can be reduced.

In the automatic mahjong apparatus of the present invention, either the first magnetic body or the second magnetic body may be replaced with a magnetic body having a polarity, for example, a magnetic body made of a magnetically attracted metal material such as iron or nickel. The present invention can be modified into various embodiments.
