Description

  The present invention relates to a pachinko ball supply device for supplying a prize ball to a prize ball tank of a pachinko machine in a pachinko machine.

  Each pachinko machine constituting the pachinko island is configured such that a ball for a prize ball is replenished in a timely manner from a ball replenishment basket to a prize ball tank via a ball replenishment device. Examples of such a ball supply device are described in Patent Document 1, Patent Document 2, or Patent Document 3.

  For example, Patent Literature 1 and Patent Literature 2 include a cylindrical supply cylinder that can be in a suspended state and a front standing state, and an operating rod that is provided so as to rotate simultaneously with the supply cylinder, and closes the front frame. A prize sphere replenishing device in which the rear side wall of the prize sphere tank is engaged with an operating rod in the process, the operating rod and the supply cylinder are rotated, the supply cylinder is suspended, and the prize sphere can be discharged from the supply cylinder is described. Has been.

  However, if the shape of the supply cylinder is flat or cylindrical, when the supply cylinder descends to replenish the sphere, if the sphere already stays in the lowered position, it will be lowered. In some cases, the replenishment rod bites the ball between the prize ball tank and the replenishment cylinder stops at that position.

  In this state, the ball is supplied from the supply cylinder to supply the ball to the height of a predetermined level or more in the prize ball tank, and the supplied ball falls down from the prize ball tank due to some impact or the like. There is a case. That is, this ball spill trouble is caused by the fact that the supply cylinder does not descend to the normal supply position.

  In this way, if a ball spills, an error ball may be produced or the back pack of the pachinko machine may be damaged. In addition, the spilled ball may hit the game equipment (hereinafter sometimes referred to as an island) to damage the island. Here, if an error ball is generated, it becomes impossible to correctly grasp the balance of the ball, that is, the number of balls that the player has struck and the number of balls that the game store has paid out. For this reason, an erroneous determination may be made, resulting in a decline in service and sales.

  On the other hand, extra pressure is applied to the prize ball tank due to the pressure of the ball sandwiched between the supply cylinder and the prize ball tank, which may lead to deformation or breakage of the prize ball tank.

  The present invention has been made in view of the above-described problems, and the object of the present invention is to guide the supply tube to the correct position without pinching the sphere and minimize the occurrence of spilled spheres and damage to the island. An object of the present invention is to provide a pachinko ball supply device.

In order to solve the above-mentioned problem, in the invention according to claim 1, in the island facility of the pachinko game shop, the balls for the prize balls are replenished from the ball replenishment bowl toward the prize ball tank of each pachinko machine, and the balls are aligned. A pachinko ball replenishing device having a ball passage that passes through the ball introduction rod having a ball introduction port that opens upward and a ball discharge port that opens downward is pivotally attached to be pivotable in the vertical direction. When the ball introduction rod is raised, the stop means for stopping the outflow of the ball from the ball outlet, the front frame open / close state detection means for detecting the open / close state of the front frame of the pachinko machine, the stop means and the front face Interlocking means for linking the frame opening / closing state detecting means, and when the front frame opening / closing state detecting means detects that the front frame is in the closed state, the ball introduction basket is lowered by the interlocking means, and the prize ball tank The ball is replenished against the ball The portion contacting the sphere stored in Nyutoi of prize balls in the tank, when the ball introduced gutter is lowered, enters between the sphere, a guide portion is provided for moving the abutting spheres presses Yes .

The guide portion is characterized in that a cross-sectional shape perpendicular to the passing direction of the sphere is formed in a substantially V shape.

The invention according to claim 2 is the pachinko ball replenishing device according to claim 1 , wherein the guide portion is formed in a substantially reverse-helix shape along the passing direction of the sphere.

  According to the present invention, when the ball introduction rod descends, the abutting ball can be moved by the guide portion, so that the ball introduction rod can be guided to a predetermined correct position without being caught. . For this reason, it is possible to suppress as much as possible the spilling of the ball from the prize ball tank due to the ball introduction rod stopping in the middle of the descent and supplying the ball at this position. Therefore, it is possible to minimize the generation of error spheres due to the occurrence of spilled spheres and the damage to island facilities due to the falling spilled spheres.

  The present invention will be described below with reference to an embodiment shown in the drawings. At pachinko parlors, a group of so-called islands configured by arranging a plurality of pachinko machines 100 in a row is used as a unit for control and circulation of balls. As shown in FIG. 11, this island generally includes pachinko machines 100 arranged back-to-back, a ball supply basket 210 disposed in the upper part of the pachinko machine 100, and a ball collection basket disposed below the pachinko machine 100. 220, a lifting device (not shown) for lifting the balls collected by the ball collecting basket 220 to the ball supply basket 210, a cleaning device (not shown) for washing the collected balls, and the like are disposed as appropriate. is there.

  The ball replenishment basket 210 is formed with a downward slope so that the ball can flow from the lifting device to the pachinko machine 100 located at the end of the island, and branches the ball supply pipe 230 to each pachinko machine 100. Then, by letting the tip of the ball supply pipe 230 face the prize ball tank 110 provided on the front frame of the pachinko machine 100, the balls flowing down from the ball supply basket 210 are supplied to the prize ball tank 110. A pachinko ball supply device 300 according to the present invention is disposed at the tip of the ball supply tube 230.

  The pachinko ball supply device 300 counts the balls to be supplied when the balls are supplied to the prize ball tank 110 provided on the front frame of the pachinko machine 100, and stops the supply of the balls when the ball is stopped. . In addition, when the front frame of the pachinko machine 100 is opened, the ball outlet of the ball supply tube 230 is sealed so that the ball flowing from the ball supply basket 210 does not flow out of the ball supply tube 230. .

  Therefore, for example, as shown in FIG. 8, the pachinko ball supply device 300 has a counting means 310 that counts the number of balls supplied to the prize ball tank 110 through the ball supply pipe 230 and a ball when the front frame 120 is in an open state. Stop means 320 for preventing the ball from spilling from supply pipe 230, front frame opening / closing state detection means 330 for detecting that front frame 120 is in the open state, stop means 320 and front frame opening / closing state detection means 330 Interlocking means 340 for interlocking with. Further, as shown in FIG. 1, when the number of award balls paid out to the player reaches a predetermined number, a hitting means 350 for stopping subsequent games is provided.

  Although the detailed description is omitted, the counting means 310 is a unitized member, and a vertical spherical passage is formed in a storage box formed in a substantially rectangular parallelepiped, and is pivotally attached to the storage box. The tip of the sprocket faces the ball passage, and when the sprocket makes one revolution, 10 balls are counted. At this time, a predetermined count signal is sent according to the rotation of the sprocket from a count signal generating means constituted by a rotating piece provided with a magnet (not shown), a reed switch or the like.

  The pachinko ball supply device 300 includes a ball introduction rod 400 for guiding the ball to the prize ball tank 110, and a stop means 320 for stopping the outflow of the ball from the ball introduction rod 400. Then, as described later, the ball introduction rod 400 can be displaced to a position where the ball can flow out and a position where the ball cannot flow out, as a part of the stopping means 320. Function as. Further, the pachinko ball supply device 300 includes a front frame open / close state detection means 330 for detecting the open / close state of the front frame 120 of the pachinko machine 100. Furthermore, the front frame open / close state detecting means 330 and the interlocking means 340 for connecting the stop means 320 are provided.

  The ball introducing rod 400, the stopping means 320, the front frame open / closed state detecting means 330, and the interlocking means 340 are attached to a metal base substrate 360. In addition, the pachinko ball supply device 300 is provided with a substantially horizontal L-shaped connecting member 371 so as to be swingable so as to be connected to the ball supply tube 230. Further, a wiring with a connector 372 for taking out a signal of the counting means 310, a wiring with a connector 373 connected to the microswitch, and a wiring 374 of a latching solenoid 352 provided as a driving source described later are provided.

  The ball introduction rod 400 is pivotally attached to the base substrate 360 so as to be rotatable in the vertical direction. As shown by a solid line in FIG. 3, the ball introduction rod 400 is shown by a broken line in FIG. Thus, it can be displaced to a state of hanging downward. Further, the ball introduction rod 400 is urged by a spring 321 so as to rise and maintain a substantially horizontal state. When the ball introduction rod 400 is in a substantially horizontal state, the ball does not flow out from the ball introduction rod 400. That is, the ball introduction rod 400 functions as a part of the stopping means 320 when in the substantially horizontal state.

  The displacement of the ball introduction rod 400 is performed by the front frame open / close state detecting means 330 and the interlocking means 340. That is, when the front frame 120 of the pachinko machine 100 is shifted from the open state to the closed state, the detection lever 331 provided as the front frame open / closed state detection means 330 is connected to the prize ball tank 110 provided on the back side of the front frame 120. When it rotates in contact with the rear wall 110a, this rotational movement is transmitted to the above-mentioned ball introduction rod 400 by the interlocking means 340, and the ball introduction rod 400 is lowered.

  The interlocking means 340 is a cam mechanism that rotates around a shaft provided at an appropriate position of the base substrate 360. For example, as shown in FIG. 1, the detection lever 331 is integrally formed with a rotation lever 332 having a rotation axis in the vertical direction, and the detection lever 331 is attached to the base substrate 360 by a coil spring 333. It is energized. In this energized state, the ball introduction rod 400 is raised and the outlet of the ball passage of the counting means 310 is closed, so that the ball does not flow out. The rotation lever 332 is in communication with the pressing lever 334, and the pressing claw of the pressing lever 334 is inserted into the ball passage of the counting means 310 to prevent the inflow of the sphere from the sphere supply pipe 230 to the counting means 310. Blocking at the entrance side of the ball passage. That is, the pressing claw of the pressing lever 334 functions as the stopping means 320 on the inlet side of the ball passage, and the ball introduction rod 400 functions on the outlet side of the ball passage.

  Further, a striking claw provided on a striking lever 351 constituting the striking means 350 faces the ball passage of the counting means 310 so as to overlap the above-mentioned pressing claw. The hitting claw is operated by a latching solenoid 352 provided as a drive source. That is, when the predetermined number of replenishments are completed and the ball is stopped, the latching solenoid 352 is operated to insert the ball pawl into the ball passage of the counting means 310 to stop the supply of the ball.

  Next, the ball introduction basket 400 will be described with reference to FIGS. The ball introduction rod 400 is formed by combining two parts molded from a synthetic resin. That is, the ball introduction rod 400 is divided into the first component 410 and the second component 420 at a position slightly deviated from the center in the longitudinal direction. Therefore, the first part 410 and the second part 420 are combined at a predetermined position, and the assembly part 430 provided on both parts 410 and 420, specifically, the assembly part 431a provided on the first part 410. , The assembly portion 431b, and the assembly portions 432a and 432b provided in the second component 420 are screwed to a not-shown screw to form an integral ball introduction rod 400. It should be noted that the number of divisions of the ball introduction rod 400 is not limited to two parts, and may be further finely divided, or may be integrally formed if possible. Moreover, although the assembly part 430 is provided and screwed in two places, it is not restricted to this, It is also possible to apply other fixing means, such as making it fit or using an adhesive agent. It is.

  By the way, since the ball introduction rod 400 functions in a state where the first component 410 and the second component 420 are assembled and integrated, when the ball introduction rod 400 is referred to, it is assembled unless otherwise specified. It shall refer to the state.

  The sphere inlet 400 has a sphere inlet 441 that opens upward and a sphere outlet 442 that opens downward. Further, the ball introduction rod 400 is provided with bearing portions 451 and 452 for axial mounting in the horizontal direction. The ball introduction port 441 can communicate with the ball passage of the counting means 310 when the ball introduction rod 400 is rotated downward and is in a suspended state. Further, when in the hanging state, the ball outlet port 442 opens sideways, and the ball can flow out through the ball passage. On the other hand, the ball outlet port 442 opens upward when the ball introduction rod 400 is rotated upward and is in a substantially horizontal state. At this time, since the sphere introduction port 441 and the exit of the sphere passage are misaligned, the sphere does not flow into the sphere introduction rod 400 from the sphere passage, and the sphere flows out from the sphere outlet 442 of the sphere introduction rod 400. There is nothing.

  On the other hand, on the tip side of the ball introduction basket 400, when the ball introduction basket 400 descends, the portion that comes into contact with the ball stored in the prize ball tank 110 enters between the stored balls. A guide portion 460 for pressing and moving the sphere is provided. That is, a guide portion 460 that allows the ball introduction rod 400 to be rotated to a predetermined position by removing a ball that hinders the rotation of the ball introduction rod 400 is provided.

  For example, as shown in FIGS. 5 to 7, the guide portion 460 is formed in a so-called boat bottom type. That is, the cross-sectional shape orthogonal to the passing direction of the sphere is formed in a substantially V shape. Moreover, it is formed in the shape of a substantially reverse shape along the passing direction of the sphere.

  Specifically, the first inclined surface 461 provided on the first component 410 and the second inclined surface 462 provided on the second component 420 are abutted at the inner end portion to form the vertex, in other words, the ridge line in the longitudinal direction. Is formed. In the illustrated embodiment, the inner end portion of the second inclined surface 462 is slightly extended in the horizontal direction to form a strip-shaped ridge line portion 463.

  As described above, the ball introduction rod 400 has a substantially V-shaped outer shape. Thus, by making it substantially V-shaped, when the ball introduction basket 400 descends and comes into contact with a ball stored in the prize ball tank 110, it comes into contact with the first inclined surface 461 and the second inclined surface 462. The ball easily escapes to the side, and the ball can be prevented from being bitten between the rear wall 110a of the prize ball tank 110 and the ball introduction rod 400. Moreover, by making the front end side of the ball introduction basket 400 into a substantially inverted shape as described above, it is possible to prevent the ball from being bitten between the ball introduction basket 400 and the bottom surface of the prize ball tank 110. .

  In this embodiment, the ridge line portion 463 is formed on the ball introduction rod 400. However, the ridge line portion 463 is not formed, and when the first inclined surface 461 and the second inclined surface 462 are joined, a substantially V-shaped portion is formed. You may make it form a vertex part.

  On the other hand, on the outer end portions of the first inclined surface 461 and the second inclined surface 462, a first vertical surface 464 and a second vertical surface 465 facing each other substantially in parallel are extended. The first inclined surface 461 and the second inclined surface 462 are not flat surfaces but curved surfaces that are slightly curved. Also, the outer surfaces of the first inclined surface 461 and the second inclined surface 462 are slightly curved at the front end portions thereof, that is, the first front end surface 466 and the second front end surface 467 which are bent in a substantially reverse hemispherical shape. Yes. In the present embodiment, as described above, the first inclined surface 461, the second inclined surface 462, the first front end surface 466 and the second front end surface 467 are configured to bend the outer surface slightly, but do not form a curved surface and are flat. It may be a surface.

  The ball introduction rod 400 provided with such a guide part is rotated by the interlocking means 340. That is, when the front frame 120 opens and closes, the movement of the detection lever 331 that contacts the prize ball tank 110 is transmitted to the ball introduction basket 400 by the interlocking means 340. The interlocking means 340 is constituted by a cam mechanism, for example. The first part 410 of the ball introduction rod 400 is provided with a long-holed interlocking hole 471 that receives an interlocking pin (not shown) that constitutes a part of the interlocking means 340.

  Therefore, when the detection lever 331 that is the front frame 120 front frame open / closed state detection means 330 is pressed and rotated by the rear wall 110a of the prize ball tank 110 as the front frame 120 is closed, this rotation is linked to the interlocking means 340. Are transmitted to the interlocking pin and the interlocking hole 471, and the ball introduction rod 400 rotates downward with the rotational shaft as a fulcrum.

  When the ball introduction rod 400 having such a shape rotates downward with the rotation shaft as a fulcrum, the tip of the ball introduction rod 400 descends and comes into contact with the ball in the prize ball tank 110. As shown in FIG. 10, the ridge line portion 463 of the sphere introduction rod 400 enters just like a wedge between the spheres P1 and P2, and the spheres P1 and P2 are in contact with the first inclined surface 461 or the second inclined surface 462. Is pressed in the tangential direction. For this reason, the spheres P1 and P2 that have been pressed move to the side, the sphere in contact with the moved sphere also moves, and each sphere moves sequentially.

  Then, the ball introduction rod 400 can continue to rotate while removing the ball in contact with the ball introduction rod 400, and can reach a predetermined rotation position. That is, it is possible to prevent the sphere stored in the prize ball tank 110 from interfering with the rotation of the ball introduction basket 400 as much as possible. Therefore, the lowering (turning) of the ball introduction rod 400 is less likely to stop midway. For this reason, although the ball introduction rod 400 is in the middle of rotation, the ball flows out, and the outflowed ball falls into the island and is sandwiched between the prize ball tank 110 and the island facility, Occurrence of damage to the island facilities with a dropped ball can be minimized.

  Although the present invention has been described with reference to the illustrated embodiments, the present invention is not limited to the above-described embodiments, and can be appropriately implemented without changing the configuration described in the claims. For example, the interlocking means is constituted by a cam mechanism, and the ball introduction rod is mechanically lowered, but the front frame open state detecting means is constituted by an electric sensor, and the interlocking means is constituted by an electric drive source, The ball introduction rod may be moved electrically.
