Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to an elevator adjustment mechanism for a tile alignment unit in a fully automatic mahjong table.In particular, the introduced tiles are moved by a conveyor after being stirred, and the tiles are moved to a standby table. After being stacked in two tiers, they are transferred to the elevator table and then lifted onto the mahjong table top, to prevent any difference in level or play between the elevator table and the mahjong table top. This allows the generation to be easily adjusted.

(Problems to be Solved by Prior Art and Ideas) Conventionally, various types of elevators for tile alignment units have been provided, but as an example, as shown in FIG. The elevator is moved up and down by operating rollers protruding from the side, and the elevator moving up and down is supported by elevator support rods on both sides of the elevator, and the elevator support rods are supported by support shaft holders.

Therefore, even if the height of each tile alignment unit is adjusted and assembled during manufacturing and assembly, the height cannot be adjusted until after the four tile alignment units have been assembled, resulting in a difference in level after assembly. Once it was put away, it had to be reassembled, which took time and increased costs.

In addition, after many years of use, the bearings inserted into the bearing holes at the top of the support shaft holder wear out, causing the elevator support rods to wobble, resulting in bumps in the elevators, which can cause tiles to get caught during games, interfering with the game. It was coming. Therefore, the store clerk went out of his way to open the top plate.
Repairs were carried out by removing the tile alignment unit, which is a complex and difficult-to-reach area. That is, in the past, the structure had many problems during assembly and repair.

(Means for Solving the Problems) The present invention was devised to solve the above problems, and the tiles created by the tile extrusion device installed adjacent to the tile alignment unit are transferred from the waiting stand to the elevator. This is an automatic mahjong table that has tile alignment units arranged at four locations on the board that raise the tiles after they have been transferred, and the tile alignment unit has an elevator support shaft holder on both sides in which the elevator support rods are loosely fitted up and down. the elevator support shaft holder is provided with a vertical operation mechanism in the center thereof, and the elevator support shaft holder has a bearing hole in the upper part and an adjustment hole having a diameter larger than the bearing hole in the lower part thereof. In addition, the difference in level is made into a step part, the step part becomes a stopper of the elevator support rod, an adjustment member is attached to the lower end of the elevator support rod, and the adjustment member is operated through the height adjustment hole drilled in the board to adjust the elevator. The horizontal level can be adjusted.

indicates the tile arrangement unit.

Reference numeral 1 denotes an elevator, in which 34 tiles stacked in two levels are transferred from a standby table by a tile pushing device, and an operating disk 10, which is a vertical operating mechanism provided in the center, rotates. As shown in FIG. 2, the operating roller 11 protruding from the outer periphery of the operating disc 10 moves up and down via the elevator support plate 12 in accordance with the rotational movement, and due to this up and down movement. With the rise, the two-tiered standby tiles are arranged on the mahjong table.

Reference numeral 2 denotes two elevator support rods that support the elevator 1. The upper ends of the elevator support rods 2 are fixed to the elevator 1, which moves up and down by the rotation of the operating disk 10, so that they move in synchronization with the elevator 1. The elevator 1 moves up and down and operates while keeping the elevator 1 horizontal.

3 is a support shaft holder, as shown in FIG. 1, a bearing hole 4 is provided in the upper part, and an adjustment hole 6 having an inner diameter larger than the bearing hole 4 is inserted in the lower part of the bearing hole 4. . A step 6a is formed at the upper end of the adjustment hole 6, and serves as a stopper when the elevator support rod 2 is raised. Further, a bearing 5 is fitted into the bearing hole 4 so that the elevator support rod 2 slides smoothly without rattling, and is interposed between the elevator support rod 2 and the support shaft holder 3 to prevent wear. .

7 is an elevator support rod 2 inserted into the bearing hole 4
The adjustment member is provided at the lower end with a flat washer 8 and a spring washer 9 interposed therebetween, and the flat washer 8 and spring washer 9 utilize the stepped portion 6a to lock the elevator support rod 2. If the table surface of the elevator 1 is tilted when the elevator 1 rises and is not flush with the top of the mahjong table and a difference in level occurs, a tool such as a screwdriver can be inserted through the height adjustment hole 14 drilled in the board 13. The adjustment member 7 can be easily adjusted using the .

10 is an operating disk in tile alignment unit A;
It is designed to be rotated by a motor M, and one actuating roller 11 is provided protruding near the outer periphery, an elevator support rod 12 abuts on the actuating roller 11, and the rotational movement of the actuating roller 11 is caused by the elevator support plate. 12
is converted into vertical movement.

Next, to explain the operation of this embodiment, the elevator 1 rises while keeping it horizontal with the elevator support plate 12 and the two elevator support rods 2 from both wings, but if a difference in level occurs with the top of the mahjong table. As shown in FIG. 5, the base surface of the elevator 1 may be lowered by using the adjustment member 7 through the height adjustment hole 14 formed in the base plate 13 using an adjustment tool (such as a drive).

That is, by tightening the screws, bolts, etc., which are the adjustment members 7 provided at the lower end of the elevator support rod 2 on the side that protrudes from the top plate of the mahjong table,
The length of the elevator support rod 2 until the flat washer 8 is locked to the stepped portion 6a in the support shaft holder 3 is shortened so that the top plate of the mahjong table and the base surface of the elevator 1 are on the same plane. Adjustment can be easily made by

Conversely, if the base of the elevator 1 is lower than the top of the mahjong table, the adjustment member 7 may be loosened and the elevator support rod 2 may be lengthened. elevator 1 at the same time
Since it is supported at three points: the two elevator support rods 2 equipped with the adjustment member 7 and the operating roller 11, there is no wobbling.

(Effect of the invention) As is clear from the above explanation, the tile alignment unit has elevator support shaft holders on both sides into which the elevator support rods are loosely fitted up and down, and a vertical operation mechanism in the center of the elevator support shaft holders. The elevator support shaft holder has a bearing hole in the upper part and an adjustment hole in the lower part which has a diameter larger than that of the bearing hole. Therefore, by attaching an adjustment member to the lower end of the elevator support rod and adjusting the level of the elevator by operating the adjustment member through a height adjustment hole drilled in the board, it is possible to adjust the level during manufacturing and assembly. This has the effect of eliminating the need to reassemble it again even if a step occurs after assembly.Furthermore, the bearing fitted into the support shaft holder wears out over time, causing the elevator support rod to wobble.
Even if a level difference occurs in the elevator, it has a remarkable effect that anyone can easily repair it in a short time and without opening the top board or disassembling the tile alignment unit.
