Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a turntable for stirring tiles in an automatic mahjong table, which is used to stir a set of tiles after a game has been completed in the mahjong table.

[Conventional technology]

A conventional turntable for stirring tiles has a sloped surface that is gently sloped from the center toward the periphery, and the peripheral edge that is continuous with this sloped surface is a horizontal surface, and the base of the turntable is made of an iron plate. Generally, a turntable with a rubber coating on the top surface is used to provide a soundproofing effect when tiles fall from the tabletop, and as a means to improve the agitation and conveyance of tiles.

[Problem that the invention attempts to solve]

Usually, a turntable has a pulley fixed to it for rotation transmission, and since the turntable is made of iron plate, its structure is heavy and becomes a considerable burden during assembly. Accuracy is affected by the base itself, which is made of iron plate, and there is a manufacturing problem in that it is extremely difficult to obtain precision when forming the peripheral portion into a horizontal surface. Furthermore, when the humidity increases, the friction on the rubber surface increases, which deteriorates the ability to stir and spread the tiles, causing a functional problem in that it takes a lot of time to send the tiles from the turntable to the next operation section. It was hot.

[Means to solve the problem]

This invention solves the above problems, and
The purpose of this is to form the base of the turntable using synthetic resin, and partially cover the rubber coated on the top of the base with cotton cloth, so that the tiles that fall onto the turntable are affected by humidity. To provide a turntable for stirring tiles of an automatic mahjong table which is improved so as to avoid the problem and to be advantageous in terms of accuracy, weight, and cost. Therefore, the above object of the present invention is to provide a rotary disk which is provided with an inclined descending surface portion which is gently inclined from the center portion toward the outer circumferential direction, and in which a peripheral portion continuous to the inclined descending surface portion is formed as a horizontal surface portion, and In a turntable for stirring tiles of an automatic mahjong table with rubber coated on the top surface of the board, the rotary disc is made of synthetic resin, and on the rubber coated on the top surface of the rotary board,
This is achieved by a turntable for stirring tiles of an automatic mahjong table, which is constructed by covering a portion of cotton cloth from the middle part of the inclined descending surface part to the boundary part between the inclined descending surface part and the horizontal surface part.

【Example】

The rotary disk 1 is a molded product made of synthetic resin,
The upper surface of the rotary disk 1 is formed by an inclined descending surface portion 3 that is gently inclined from the center portion 2 toward the outer circumference, and a horizontal surface portion 4 that is continuous with the inclined descending surface portion 3. It corresponds to the peripheral part. Rubber 6 is adhered (thermally bonded) to the upper surface of the rotary disk 1 except for the shaft support hole 5 drilled in the center portion 2, and
A cotton cloth 8 is adhered (thermally bonded) onto this rubber 6 from a stepped portion 6a provided at the middle portion of the inclined descending surface portion 3 to a boundary portion 7 between the inclined descending surface portion 3 and the horizontal surface portion 4. Implement. In this case, the part of the rubber 6 to which the cotton cloth 8 is applied is formed into a shallow concave part with a depth approximately equal to the thickness of the cotton cloth 8, and the cotton part 8 is placed flush with the other parts of the rubber 6. It is desirable to do so. Further, a gear 9 is integrally formed concentrically with the rotary disk 1 on the lower side of the rotary disk 1, and an internal gear portion 9 thereof is formed concentrically with the rotary disk 1.
a can be used as a driving gear for the rotary disk 1 itself, and the external gear part 9b can be used as a driving gear for other related members.

[Effect of the idea]

The present invention is as described above, and since the base body of the turntable is made of synthetic resin, it is lightweight, it is easy to achieve precision during molding, and the rubber and cotton cloth are adhered to the turntable by thermal bonding. It has the manufacturing advantage of being able to be integrally connected to the turntable, and since the turntable is constructed by covering the middle part of the upper surface of the turntable with cotton cloth, the influence of humidity on the tiles is reduced, and friction is reduced, making it easier for the tiles to move. It has good sliding properties and is excellent in stirring and diffusing tiles, and has the effect of further improving the original function of the turntable for stirring tiles. In addition, because the power transmission gear can be integrally molded with the rotary disk, unlike conventional turntables of this type that are assembled with separately manufactured pulleys, fewer parts are required, resulting in significant cost reductions. , its practical value is extremely great.

[Brief explanation of drawings]

The drawings show an embodiment of the present invention, and FIG. 1 is a front sectional view, and FIG. 2 is an enlarged view of portion A in FIG. 1. In the figure, 1 is a rotary disk, 2 is a central part, 3 is a sloped surface part, 4 is a horizontal part, 6 is a rubber, 7 is a boundary part, 8
is cotton cloth, and 9 is a gear.
