Description

The present invention relates to a ball dispensing equipment of the game machine for paying out one by one ball ball sent into the upstream of the ball tank as a prize ball.

A mechanism board is provided on the back surface of the pachinko machine, and a ball tank for storing prize balls is disposed on the upper part of the mechanism board. A ball passageway is connected below the ball tank. Conventionally, there is a ball dispensing device that uses a ball passage device (ball alignment rail) to align (especially align in one step) and then pays out with a ball dispensing device. However, ball biting occurs at the portion that is aligned from the second step to the first step, so the swinging weight is hung on that portion (Patent Document 1) or vibrated (Patent Documents 2 and 3). It was solved. However, there is a problem that the former lacks certainty and the latter requires additional power.
Therefore, it is conceived that the latter power for breaking the ball is covered by the power for dispensing, that is, the ball is unaligned from the tank without being aligned and is broken out by the ball dispensing device and then dispensed (Patent Document 4). . However, if they are left unaligned, the possibility of arch (tunnel) ball biting as shown in FIG. 8 could not be excluded.

Hereinafter, embodiments of the present invention will be described.
FIGS. 1-7 is a figure which shows embodiment of this invention, Comprising: 1 is a ball tank, 2 is the ball path apparatus provided in connection with the ball tank, Comprising: This ball path apparatus 2 is a ball path. It consists of a basket 3 and a ball dispensing device 4.

  The ball passageway 3 is formed in a concave groove shape, and has a lateral width of more than 2 balls to less than 3 balls (when the ball diameter is 11 mm, more than 22 mm and less than 33 mm). Moreover, the height of the side surface 31 is also set to be more than two balls and less than three. Since the width and height of the ball passage 3 are larger than two balls, it is possible to completely prevent clogging caused by two balls arranged side by side in the horizontal direction or the vertical direction. The bottom surface of the ball passage rod 3 is formed with angle-shaped ridges 32 that are high in the center and low on both sides and extend in the longitudinal direction, and ball guide grooves 33 are formed on both sides of the ball passage rod 3.

The ball payout device 4 is arranged at the downstream end of the ball passageway 3, and a ball guiding path (not shown) for paying out the prize balls is connected to the lower side. The ball dispensing device 4 includes a rotating body 50 that is rotated by a motor M and a housing 6 that supports the rotating shaft 5 of the rotating body 50 in a horizontal state.

The housing 6 has a ball entrance 61 for receiving a ball from the ball passageway 3 at the upper portion, and a ball introduction path 65 is formed in communication with the ball entrance 61 (FIG. 3). Below the ball introduction passage 65, a ball dispensing passage 63 having a ball counting sensor 62 is formed close to one side surface of the housing 6. Between the ball introducing passage 65 and the ball dispensing passage 63, the rotating body 50 provided with two sprockets 7 to the rotary shaft 5 is interposed a rotary shaft 5 as a horizontal state, the rotary member 50 by a motor M It is rotated. Reference numeral 64 denotes a ball removal passage for removing balls in the pachinko machine for maintenance or the like, and is not used during the game. When the ball is removed, the motor M is rotated in the reverse direction.

  The ball entrance 61 has a width and a height that are more than two balls and less than three balls in the same manner as the ball passageway 3 and prevents clogging by two balls. The ball introduction path 65 has a square or rectangular horizontal cross-sectional shape, and its lateral width and vertical width (height) are more than 2 balls and less than 3 balls as shown in FIGS. It is prevented. In addition, a concave wall surface 66 is formed on the side surface of the casing on the lateral side of the rotating body 50, and a gap through which one ball can pass is provided between the outer peripheral surface of the rotating shaft and the concave wall surface 66. The ball can flow downward.

Two sprockets 7a and 7b are fixed to the rotary shaft 5 at a required interval. This space | interval is set as the space | interval which can receive one ball between the housing | casing 5 side surfaces which the sprockets 7a and 7b oppose. The sprocket 7 has three recesses ( ball receiving portions) 71 for receiving balls on the outer periphery. The positions of the recesses 71 of the sprockets 7a and 7b are shifted so that the flanges of the other sprocket 7b are positioned in the recesses 71 of one sprocket 7a as shown in FIG. 3 and FIG. When the ball enters the recess 71 of the other sprocket 7a, for example, the ball is placed on the outer edge of the flange of the sprocket 7b in the other sprocket 7b so that the ball does not enter the recess 71 (FIG. 4). . Since the chamfered portion 72 is formed obliquely inwardly at the tip of the collar portion of the sprocket 7, when there is no ball in the concave portion 71 of the sprocket 7a, a ball riding on the outer edge of the collar portion of the other sprocket 7b. The sprocket 7a enters the recess 71. Therefore, the recess 71 of the sprocket 7a and the recess 71 of the sprocket 7b can alternately receive and pay out balls.

  The ball payout passage 63 is reduced in width so that one ball can pass from directly under the rotating shaft 5 to the ball counting sensor 62. Since one ball is paid out alternately from the rotating shaft 5, the ball is not clogged even if the ball payout passage 63 is reduced from about two balls to about one.

In what is configured as described above, the ball delivered from the ball tank 1 flows down in the ball passageway 3 downstream. The balls are not neatly distributed into the two guide grooves 33 by the Yamagata ridges 32, but are present at the top of the Yamagata ridges 32, and the inside of the ball passage ridge 3 is stunned in two steps and two rows. It flows down in the state. Then, the balls flow into the housing 6 from the ball entrance 61, and flow into the ball introduction path 65 in two or more rows and less than three or three rows. In the ball dispensing state, the sprocket 7 causes the ball train to collapse while being stirred. Therefore, it is necessary for the ball introduction path 65 to have a play space that is not completely filled with the ball and that can be stirred and moved. is there. Sprockets 7 are rotated by the ball is after having entered alternately in the recess 71 of the two sprockets 7a, 7b, are sent one by one ball below ball dispensing passage 63.

  As described above, since the ball is not reduced in height or width to two balls or less until the ball is taken into the sprocket 7, the ball is continuously discharged without causing clogging by two balls. be able to. Then, the counting sensor 62 counts the number of balls passed, and when it reaches a predetermined number, the rotation of the sprocket 7 is stopped. The present invention has an advantageous effect that the risk of causing clogging of balls is remarkably reduced because it is not necessary to align the balls in a line.
