Description

  The present invention relates to a ball dispensing device for a gaming machine that can dispense many balls such as pachinko balls per unit time and can eliminate clogging of balls.

2. Description of the Related Art A ball dispenser for a gaming machine is known that has the following structure. An opening is formed in the bottom surface of the tank structure, and a dispensing mechanism is provided at the lower part of the tank structure so as to be located at the lower part of the opening, and the spiral dispensing structure in the dispensing mechanism is the tank structure. One direction so that the payout motor rotates in the circumferential direction in a state where the payout motor of the payout mechanism is provided outside the tank structure and the ball is supplied to the inside of the tank structure. , The dispensing structure separates the balls one by one and dispenses them from the tank structure to the dispensing ball detector side. The payout structure includes a payout shaft and a spiral body, and the spiral body protrudes in a spiral shape radially outward from the outer peripheral surface of the payout shaft at intervals separating the spheres one by one in a direction parallel to the axis of the payout shaft. This is the structure. In a ball payout device for a gaming machine equipped with such a payout structure, when the number of payout balls per unit time (for example, 1 minute) is increased, the spiral body separates in a direction parallel to the axis of the payout axis. It is conceivable to reduce the distance between the sphere centers of two adjacent spheres (hereinafter referred to as a sphere interval H). However, if the distance between two adjacent spheres is narrowed, there is the following inconvenience. Therefore, it is obvious that increasing the number of balls to be dispensed per unit time by narrowing the sphere distance H will be adopted. I want. The inconvenience when the sphere interval H is narrowed will be described with reference to FIG. Assuming that the payout structure 200 including the payout shaft 203 and the spiral body 202 is rotationally driven in one direction indicated by an arrow a in FIG. 9a, the sphere P1 existing on the back side of the payout structure 200 is removed from the spiral body 202. While receiving a downward force, the ball P2 existing on the front side of the ball dispensing structure 200 receives an upward force from the spiral 202 while falling by its own weight to the dispensing ball detector (not shown) without being lifted from the ball receiving bottom surface 201. Therefore, after being lifted from the ball receiving bottom surface 201, the weight falls to the payout ball detector side. That is, as shown in FIG. 9a, the sphere P2 falls by its own weight after being lifted from the position indicated by the phantom line to the position indicated by the solid line. In this ball paying-out operation, the ball P2 is shown in the b and c diagrams of FIG. 9 until it reaches the position indicated by the phantom line due to its own weight drop after being lifted from the position indicated by the phantom line to the position indicated by the solid line. In this way, the sphere P3 conveyed by the spiral 202 following the sphere P2 may collide with the sphere P2 so as to strike the sphere P2 in the lateral direction. When such a collision between the sphere P2 and the sphere P3 occurs, the reaction of the collision causes the sphere P2 to contact the surrounding tank structure 205, and the sphere P2 is sandwiched between the tank structure 205 and the sphere P3. Causing ball clogging. For example, when the diameter of the sphere is 11 mm, the sphere interval H is set to 13 mm, and the number of revolutions of the payout motor (not shown) is set so that 500 or more spheres can be paid out per minute. When the operation was tested, frequent clogging occurred.
JP-A-8-10415

  The problem to be solved by the invention is that, when the interval between the balls determined by the spiral is narrowed, if a large number of balls are to be paid out per unit time, a ball clogging is likely to occur.

  The gaming machine ball dispensing apparatus according to the present invention is a gaming machine ball in which the dispensing structure provided inside the tank structure separates the balls stored in the tank structure one by one and discharges them from the tank structure. In the dispensing device, the dispensing structure includes a dispensing shaft and a spiral body, and the spiral body is radially outward from the outer peripheral surface of the dispensing shaft at an interval that separates spheres one by one in a direction parallel to the axis of the dispensing shaft. It is a structure protruding in a spiral shape, and the distance between the sphere centers of two adjacent spheres separated by the spiral, that is, the distance between the spheres, follows the sphere that falls by its own weight away from the spiral and this sphere. Thus, it is characterized in that it is dimensioned so that the spheres conveyed by the spiral do not come into contact with each other.

  According to the ball dispensing device of the gaming machine according to the present invention, the ball interval is set to a size such that a ball that falls by its own weight away from the spiral body and a ball that is transported by the spiral body following this ball do not contact each other. As a result, many balls can be paid out per unit time and ball clogging can be eliminated.

On the right side of the base 90, a ball extraction detector 126 that detects a ball passing through the ball extraction passage 100 is provided.

  In the detection structure 144, the base 150 is engaged and fixed to the peripheral wall 146 around the opening 145 of the mechanism housing 6 like a lid that closes the opening 145 of the mechanism housing 6 (see FIG. 2). The base 150 of the detection structure 144 is formed with a take-in port 151 through which the payout structure 4 passes and which is connected to the upper opening 21 to take the ball into the payout mechanism 3. A sphere detector holder 152 that protrudes to the left from the base 150 is provided below the intake port 151, and the dispensing ball detector 5 is held by the sphere detector holder 152. A prize ball passage 153 is provided on the right side of the base 150 and below the intake port 151.

  The payout structure 4 that protrudes to the left from the intake port 151 of the base 150 of the payout mechanism 3 configured as described above is accommodated in the payout accommodating portion of the tank structure 2 through the upper opening 21 of the tank structure 2 and discharged. A ball detector holder 152 in which the shaft portion 86 of the structure 4 is rotatably inserted into the payout bearing hole 17 and protrudes to the left from the base 150 is positioned below the payout escape hole 18 via the lower opening 22. In this state, a set screw 7 such as a tapping screw is fastened from the outside of the mechanism housing 6 of the payout mechanism 3 to the mechanism mounting portion 9 of the tank structure 2 via the housing mounting portion 8 of the mechanism housing 6. (See FIG. 2), the payout mechanism 3 and the tank structure 2 are assembled so as to be integrated with each other, and the ball payout device 1 is configured.

  With reference to FIG. 1, an operation of paying out a ball from the payout storage unit 12 of the ball storage unit 10 to the prize ball passage 153 will be described. The control device cuts off the power supply to the switching drive source 96 of FIG. 2, and the switching valve 97 projects vertically above the valve shaft 118 and intersects the dispensing shaft 82 of the dispensing structure 4. In this state, the control device drives the payout motor 13 in one direction by the prize ball payout process, and the payout motor 13 rotates the payout structure 4 in the circumferential direction of the payout shaft 82. As a result, the sphere taken into the gap of the spiral body 85 moves toward the payout mechanism 3 from the payout housing portion 12 through the upper opening 21 and the intake 151 as the payout structure 4 is driven in one direction. It becomes sphere P2. The sphere P2 comes off the spiral body 85 and falls by its own weight.

  The falling ball P2 is blocked by the switching valve 97 projecting vertically as shown by an arrow X1 so as not to go in the direction of the ball extraction passage portion 100, and is guided to the prize ball passage 153. 153 is paid out downward. The ball P <b> 2 falling in the prize ball passage 153 is detected by the payout ball detector 5. The payout ball detector 5 outputs a payout detection signal to the control device every time the ball P2 is detected. The control device counts up or down the payout detection signal to manage the number of balls to be paid out as prize balls from the ball payout device 1 and stops the payout motor 13. In the case of counting up, when the counted up value coincides with the number of prize balls paid out that triggered the payout motor 13 in one direction, the control device stops the payout motor 13. In the case of the countdown, the prize ball payout number that triggered the payout motor 13 in one direction is subtracted for each input of the payout detection signal, and when the prize ball payout number becomes zero, the control device stops the payout motor 13. .

  With reference to FIG. 1, an operation of paying out the ball P <b> 2 from the payout storage unit 12 of the ball storage unit 10 to the extraction passage 100 will be described. The control device supplies electric power to the switching drive source 96 of FIG. 2, and the switching valve 97 rotates around the valve shaft 118 toward the tank structure 2 as indicated by the phantom line, thereby discharging the discharging structure 4. It is arranged below 82. In this state, the control device drives the payout motor 13 in one direction by the ball extraction process, and the payout motor 13 rotates the payout structure 4 in the circumferential direction of the payout shaft 82. As a result, the sphere captured in the gap of the spiral body 85 moves toward the payout mechanism 3 from the payout housing portion 12 through the upper opening 21 and the intake port 151 as the payout structure 4 is driven in one direction. It becomes sphere P2. The sphere P2 falls off the spiral body 85 and falls downward under its own weight.

  The falling ball P2 is blocked from going in the direction of the prize ball passage 153 by the switching valve 97 protruding obliquely toward the tank structure 2 as shown by an arrow X2, and guided to the ball extraction passage 100. Then, it is paid out from the ball extraction passage 100 downward. The ball P <b> 2 falling in the ball extraction path 100 pushes the ball extraction sensor 126 toward the relay board 41. The lower part of the ball extraction sensor 126 rotates in the direction of the ball extraction detector 67 around the sensing axis 132, and the detected part 135 is detected by the ball extraction detector 67. The ball extraction detector 67 outputs a ball extraction detection signal to the control device every time the detected part 135 is detected. The control device manages whether or not a ball dispensed as a ball from the ball dispensing device 1 exists in the tank structure 2 according to the time interval when the ball removal detection signal is input, and stops the dispensing motor 13. When a ball to be dispensed as a ball is present in the tank structure 2, if the rotation speed of the dispensing motor 13 is constant, the time interval for inputting the ball removal detection signal is the axis of the dispensing shaft 82 in the spiral 85. It becomes constant depending on the interval (pitch) in the direction parallel to. When a ball dispensed as a ball is absent from the tank structure 2, the time interval at which the ball removal detection signal is input becomes equal to or greater than the predetermined time interval. Therefore, when the time interval at which the ball removal detection signal is input becomes equal to or longer than a certain time interval, the control device stops the payout motor 13.

  With reference to FIG. 4, the gaming machine provided with the ball payout device 1 will be described. The gaming machine frame 173 of the gaming machine includes a movable frame 175 that can be opened and closed on the front side of the fixed frame 174.

The movable frame 175 is provided with an opening 177 as a through hole in the front-rear direction. The opening 177 penetrates a back side component such as a ball guide structure or a control device attached to the back side of the game board from the front side to the back side of the movable frame 175, or a guide rail attached to the front side of the game board, A front part such as a winning part is passed through from the back side of the movable frame 175 to the front side.

  In the ball dispensing device 1, the tank structure 2 is attached to the back surface of the movable frame 175 from the back side of the movable frame 175 with a fixing tool such as a screw so as to be positioned above the opening 177. A guide rod 178 is connected to the lower portion of the relay rod 31. The guide rod 178 is attached to the back surface of the movable frame 175 from the back side of the movable frame 175 with a fixing tool such as a screw so that the guide rod 178 is positioned on the right side of the opening 177. Prepare. The prize ball passage 179 is connected to the prize ball passage 32 of the relay bowl 31. A ball discharged from the prize ball passage 179 is received by the receiving rod 181. The receiving rod 181 is attached to the back surface of the movable frame 175 from the back side of the movable frame 175 with a fixing tool such as a screw so as to be positioned below the opening 177. The ball received by the receiving rod 181 is discharged from the receiving rod 181 to the receiving tray portion of the dish structure not shown. The dish structure is attached to the front surface of the movable frame 175. The saucer part of the dish structure is a part into which a player uses a ball used for the game. Then, when the player operates the firing operation mechanism provided on the front surface of the dish structure in a state where the ball is present on the tray portion, the ball is attached to the front surface of the movable frame 175 so as to be positioned on the back side of the dish structure. The launching mechanism launches the balls supplied from the tray part one by one toward the inner game area surrounded by the guide rails of the game board. The extraction passage 180 is connected to the extraction passage 33 of the relay rod 31. The balls discharged from the ball extraction passage 180 are discharged from the back side of the movable frame 175 to the collection mechanism of the gaming machine installation structure.

However, by setting the ball interval H formed by the spiral body 85 to 18 mm and setting the rotation speed of the payout motor 13 to a value that rotates the payout structure 4 so that 750 balls can be paid out in one minute, It was possible to prevent the sphere P3 conveyed by the spiral body 85 following the sphere P2 from colliding with the sphere P2 so as to strike the sphere P2 in the lateral direction, and to eliminate the clogging. That is, it was possible to pay out as many as 750 balls per minute and eliminate the clogging.

  According to the ball dispensing device 1 of the best mode 1, the dispensing structure 4 disposed in the dispensing container 12 protruding downward from the supply port 11 of the ball storage unit 10 of the tank structure 2 is separated from the ball storage unit 10. It is driven in one direction by the dispensing motor 13 so that the direction of the ball pressure received from the sphere moving toward the supply port 11 and the direction of moving the sphere toward the ball outlet by the dispensing structure 4 are the same direction. Therefore, there is an advantage that the payout structure 4 rotates smoothly, does not easily cause ball clogging, and the ball can be smoothly paid out from the ball storage unit 10. When a ball is clogged in the ball dispensing device 1 in the process of dispensing the ball, the worker removes the set screw 7 from the ball dispensing device 1 and then the worker removes the dispensing structure 4 and the dispensing ball detector. 5 is pulled out in the direction opposite to the insertion direction of the tank structure 2 to the tank structure 2, so that the payout mechanism 3 is removed from the tank structure 2.
