Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an automatic mahjong machine, and particularly to a mahjong machine that can automatically line up washed mahjong pies and then send them onto a playing surface. This relates to the alignment and pushing mechanism.

[Prior art and its problems]

When a mahjong game ends, all the competitors do a shi-pai and line up to prepare for the next game, but the noise made during the shi-pai is loud and can cause discomfort to the neighborhood. Moreover, there were times when contestants committed cheating, such as cheating and cheating.

Several automatic Mahjong pie mechanisms have been developed to solve these problems.

The automatic alignment and push-up mechanism for mahjong pies was also developed as one of the automatic mechanisms, and a predetermined number of washed mahjong pies (17 pieces x 2 rows) are arranged in each situation on the playing surface. By automatically sending the mahjong pie up to the top, it is possible to completely prevent the player's hand from touching the mahjong pie before it is lined up on the playing surface.

However, the feeding mechanism that has been proposed so far,
In particular, a mechanism is adopted in which a predetermined number of mahjong pies are lined up and waiting on the inside of the machine in advance, and the lined up mahjong pies are sent onto the playing surface after waiting for the competition on the table surface to be completed. In the case of a machine, a plate for placing mahjong pies lined up in a predetermined number and a mechanism that engages with both ends of the plate and lifts the above-mentioned placing plate together with the mahjong pies operate linearly. In order to do this, the entire mechanism has to be large-scale, which has the disadvantage that the overall size of the device has to be increased. (The arm rods that support both ends of the mounting plate cannot be folded, so a space with the length of the arm rod as the drive radius is required, so the feeding mechanism alone requires a considerable amount of space.) [Object of the Invention] The present invention has been made in view of the above-mentioned circumstances, and its purpose is to provide a device that can easily send mahjong pies lined up in a predetermined number onto a playing surface. It is an object of the present invention to provide a mechanism for aligning and feeding mahjong pies that not only operates accurately but also has a relatively small structure.

[Key points of the invention]

In order to achieve the above-mentioned object, the present invention arranges mahjong pies fed by a stirring mechanism into two rows of a predetermined number on an arranging board on each side corresponding to a player, and arranges the pies. The alignment plate is configured to be raised and lowered by pivoting of operating links supporting both ends of the alignment plate, and the pivoting operating links move up and down along a lifting guide, thereby accurately moving the alignment plate with a relatively small stroke. It is configured so that it is on standby so that it can be sent to the competition surface.

〔Example〕

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

The aligning and feeding mechanism of the present invention, generally indicated by A, is provided in conjunction with the mahjong pie stirring and feeding mechanism B and the conveyance mechanism C that conveys the mahjong pie P...P sent out from this mechanism. be.

The above-mentioned feeding mechanism A includes an alignment plate 1 for collecting and arranging a predetermined number of pies P...P, and the alignment plate 1.
The pivot 31 supports the guide groove 2 of the guide plate 2.
1, fix the support link 3 and the base end part to the rotating shaft 4 for raising and lowering the alignment board to the competition surface,
The drive link 32 has a distal end pivotally connected to the upper end of the support link 3, and the rotation shaft 4 is connected to a motor or other appropriate power source (not shown). As illustrated in FIGS. 2 and 3, the guide groove 21 has a concave portion 22 having a gentle V-shape slightly above the middle portion of the semi-circular groove. When the pivot shaft 31 that pivotally connects the support link 3 and the alignment plate l reaches the recess 22, the alignment mechanism that is in a horizontal state starts to tilt, and eventually the L sea urchin collapses forward at an angle of 90 degrees. This is what makes it work. 5 is
The mahjong pai holder, which forms part of the table surface, is a driving gear for driving the board 6 up and down. I'm trying to drive it. The above-mentioned lifting guide rod 7 has a rack gear 71 carved on its side surface, and this gear 71
meshes with the drive gear 5 to form a rack and pinion mechanism.

8 is a sending plate for pushing out the aligned mahjong pies P...P to the front, and a pushing rod 81 provided on the back side.
It is made to push out and retreat by the reciprocating movement of. Note that although the drive source for the delivery rod 81 is not particularly shown,
It is preferable to configure it so that it can move back and forth using several solenoid rods.

Next, the operation of the device according to the present invention will be explained.

First, the mahjong pie P after the competition is dropped into the stirring and feeding mechanism B by opening the opening guide plate provided on the tabletop.
P is sent to the conveyance mechanism C while being appropriately agitated by the rotation of the rotary agitator, and finally guided to the alignment mechanism A.

The mahjong pies P guided by the transport mechanism C to the sending mechanism A are counted by an appropriate counting mechanism (not shown), and when a predetermined number (usually 17 pieces) is reached, a power linked to a sensor etc. is activated. This machine is used in a normal mahjong competition, in which a sending rod 81 that operates a pie sending plate 8 is driven, and the aligned mahjong pies P...P are sent out as they are onto the pie arranging plate 1 located in the front. Since the array of pies is 17 pieces x 2 rows, by repeating the above operation twice, the upper surface of the alignment plate 1 is arranged into a predetermined number and predetermined rows (17 pieces x 2 rows) of pies.

In this way, when a predetermined number of mahjong pies P...P are arranged on the feeding mechanism A...A's pie alignment board 1...bow, the device Its function is to pause, and in this state it waits for the next operation. (That is, wait for the competition being played on the table to end).

When the competition on the table is finished, the rotating shaft 4 of the feeding mechanism A is driven to rotate by the power that is linked to this. When the rotating shaft 4 is driven, the base end is fixed to this. At the tip of the drive link 32, which simultaneously rotates, the tip of the support link 3, which supports both ends of the alignment plate 1, is pivotally attached via a pivot shaft 31. The alignment plate 1 carrying the pies P...P rises along the guide groove 21 of the guide plate 2 as the support link 3 whose both ends are supported rises. In this case,
At the start of the ascent, the pivot 31 of the two mahjong pies P...P that were standing upright parallel to each other on the alignment plate 1 rises along the guide groove 21, and the V-shaped recess near the upper end 2
When reaching 2, the state changes from the upright state to the lying state, and the pies on the two sides at the top solstice are automatically displaced to their stacked state.

Also, when performing the above operation, on the one hand, the rotating shaft 4
As a result of the engagement of the drive gear 5 attached to the drive gear 5 and the rack gear 7 attached to the lifting guide rod 7, the lifting guide rod 7 is pulled down. Then, when the board 6 descends to the surface of the feeding mechanism A, the pie receiver located on the table surface (competition surface) is aligned exactly on that surface, and the mahjong pie P that was aligned on the alignment board 1... P is sent in and the pie receiver is moved to the 6th side of the plate. Since the rotating shaft 4 is set to perform a constant reciprocating motion within a predetermined period of time, when the rotating shaft 4 starts to rotate in the opposite direction, the alignment plate 1 into which the mahjong pies have been fed is operated in the opposite direction to the above-described operation. The board 6 descends and waits for the next stirring operation to feed the pie, and the board 6 of the pie receiver that receives the pie rises to the table surface (competition surface) so that the next game can be played.

〔Effect of the invention〕

Since the present invention is configured as described above, the mahjong pies P...P accommodated on the alignment plate 1 can be aligned in a predetermined manner on the upper surface of the alignment plate 1 in an extremely short period of time.

The link mechanism that supports both ends of the alignment plate 1 is separated into a support link 3 that directly supports both ends of the alignment plate, and a drive link 32 whose base end is fixed to the rotating shaft 4. The pivot shaft 31 portion on which the two links are pivoted is configured to fit and slide in the guide groove 21 of the guide plate 2, and furthermore,
The guide groove 21 formed in an arc shape on the guide plate 2 has a concave portion 22 inwardly recessed in a V-shape near its upper end, so that the alignment plate 1 maintains a horizontal state when performing the upward movement. As soon as the pivot shaft 31 of the pivot portion reaches the recess 22, it starts to fall forward and can finally be displaced forward at an angle of 90 degrees. As a result, the mahjong pies P...P, which were standing vertically on two sides parallel to each other at the start of the ascent, are now stacked in two tiers due to the above displacement, and the next one on the table surface. will be able to immediately respond to competitions.
