Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a pachinko ball carrier for use in processing a winning ball of a pachinko machine.

(Prior Art) Since the contents of the game on a recent pachinko machine are in the situation where a large number of winning balls are required, the winning balls must be processed promptly, and an electric means is used for this purpose. It is like this.

That is, the winning spheres are gathered in a collecting gutter and then dropped from the drop port, and the number of the winning spheres is detected by the winning sphere sensor. The output signal that the winning ball sensor detects and outputs the winning ball is input to the prize ball dispenser,
The prize ball dispenser will dispense the number of prize balls according to the signal.

(Problems to be Solved by the Invention) In the above-described conventional techniques, when the winning balls falling from the drop opening of the collecting gutter pass through the sensor, they may drop and overlap. , This caused the malfunction.

The present invention has been made to solve such a problem in the prior art, and has a structure in which even if a large number of pachinko balls continuously enter the winning opening, they do not overlap and fall. Therefore, it is an object of the present invention to provide a pachinko ball conveying device in which the sensor does not make an erroneous detection.

(Means for Solving the Problem) As a means for solving the above problems, the present invention provides a pachinko ball carrier having a cross-sectional shape below a drop port provided in a collecting gutter where prize balls are collected. It has an arc shape that matches the outer shape of the pachinko ball and the depth is less than the radius of the pachinko ball, and the pitch gradually increases from the inlet to the outlet, and the pachinko ball per rotation of the screw at the outlet. A screw having a spiral groove that becomes a lead of about 2.5 times the diameter of the screw is provided, and guide plates for holding the pachinko balls in the groove from the side surfaces are provided on both side surfaces of the screw, and the inlet of the screw is further provided. It is characterized in that a prize winning ball sensor is provided which detects a prize winning ball which is conveyed from the section to the outlet and falls from the screw and outputs a signal.

(Function) With this configuration, when the pachinko balls enter the winning opening, the winning balls gather in the collecting trough, fall from the falling opening, and are placed on the screw, and come close to both side surfaces of the screw. With the guide plate provided, the upper part of the screw is moved from the inlet part to the outlet part of the screw without falling into the lower part of the screw. This movement is aligned because the pitch of the groove of the screw gradually widens, and drops in order from the drop port. As it falls, it is counted by the sensor.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows the entire back surface of a pachinko machine, and 1 is a prize ball payout passage. A prize ball payout device 2 to be described later is interposed in the payout passage 1 and operates when a pachinko ball wins a prize and pays out a predetermined number of prize balls. The prize ball payout device 2 operates by inputting a signal from a prize ball sensor 3 which detects that a pachinko ball has won and outputs a signal.

In FIG. 2, reference numeral 4 denotes a gathering gutter, and the winning pachinko balls (winning balls 9) gather in the gathering gutter 4. The gathering gutter 4 is formed on both sides from the inside toward the inside so as to have a slanting surface with a lower center, and is attached so as to be slanted so that one end thereof is lower. A drop port 5 is formed at the lowest part in the center. A screw 6 is rotatably installed below the collecting trough 4, and one end thereof, that is, an inlet portion is exposed to the drop port 5, and the other end, that is, an outlet portion is exposed to an inlet end surface of the dropping cylinder 7. I have it. A groove 10 is formed on the screw 6 as will be described later, and the winning ball 9 is screwed onto the screw 6.
It is designed to guide in the direction of the arrow from the inlet at the right end to the outlet at the left end. Inside the falling barrel 7, a winning ball sensor 3 is provided. The pitch of the groove 10 gradually increases from the drop port 5 toward the drop tube 7 as shown in FIGS. 3 and 4, becomes smaller at the inlet portion P ₁ and becomes smaller at the outlet portion P ₁ as shown in FIG. It has grown to ₂ and has become larger gradually during that period.

As shown in FIG. 3, on both sides of the screw 6, a long distance is provided between the screw 6 and the winning ball (not shown) so that the winning ball (not shown) can move above the screw 6 without falling into the groove 10 of the screw 6. The guide plates 8 having the same size as the screw 6 are provided close to each other. The winning ball 9 is this guide plate 8,8
And the groove 10 allow the screw 6 to be held from the side, and the screw 6 does not fall into the lower part of the groove 10 of the screw 6.
Will be conveyed in the arrow direction from the inlet to the outlet.

FIG. 4 is an enlarged view of the screw 6 portion. As shown in this figure, on the outer peripheral surface of the screw 6,
The cross-sectional shape is an arc shape that matches the outer shape of the pachinko ball, the depth D is less than the radius of the pachinko ball (winning ball 9), and the pitch P is about the diameter of the pachinko ball at the entrance, and goes to the exit. At the outlet, a groove 10 is formed in a spiral shape, which becomes a lead about 2.5 times the diameter of the pachinko ball per rotation of the screw. The pitch P of the groove 10 is small at the entrance of the screw 6 and becomes the largest at the exit of the screw 6, and the prize balls 9 gathered at the entrance are gradually separated to have a constant value, and The reason is that the drop to 7 can be performed smoothly.

As shown in FIG. 2, the falling barrel 7 is provided with a winning ball sensor 3. When the winning ball 9 falls in the drop tube 7, the winning ball sensor 3 detects the winning ball 9 and outputs a signal to operate a prize ball dispenser (not shown). In addition, 11 is a motor for rotating the screw 6.

The pachinko ball carrier configured in this way is equipped with a motor.
When electricity is supplied to 11 and the screw 6 rotates, the winning ball 9 drops onto the screw 6 from the drop opening 5 of the collecting gutter 4. This falling prize ball 9 is a groove 10 of the screw 6 and a guide plate.
Guided by 8,8, it advances in the direction of the arrow in FIGS. 2 to 4, and falls into the dropping cylinder 7 at a predetermined interval. Groove 10
Since the pitch P is gradually increased toward the exit side, the pitch of the prize balls 9 that are initially in close contact with each other is gradually increased, and the prize balls 9 are smoothly transferred to the falling barrel 7.

(Effects of the Invention) Since the present invention is the pachinko ball carrier configured as described above, even if the winning balls are concentrated in the collecting gutter, the winning balls do not pass through the winning ball sensor as they are. ,
It passes through the winning ball sensor after being controlled by the screw and the guide plate so as to have a constant interval. Therefore, unlike the prior art, they do not fall over one another, and the winning ball sensors are detected one by one, so that they will not be erroneously counted.
