  Next, the game ball supply device 1 will be described in detail with reference to FIGS. 2 is an exploded perspective view of the main part of the game ball supply device 1, FIG. 3 is a side view of the main part of the game ball supply device 1, and FIG.

  The transport device 12 includes a rotating body 20 that rotates around a rotating shaft 20a extending in the short direction of the gaming island 100, and the game ball is transferred to the rotating body 20 by the magnetic force of the magnetic body disposed on the outer peripheral edge of the rotating body 20. It is made to adsorb | suck to the outer peripheral surface of and convey. Here, the outer peripheral edge of the rotating body 20 refers to an annular region surrounded by the outer peripheral surface of the rotating body 20 and a circle having a smaller diameter than the outer peripheral surface.

  Both ends of the rotating shaft 20a of the rotating body 20 are rotatably supported by a pair of support plates 31 attached to the attaching portion 15 of the game island 100.

  Since the outer diameter of the support plate 31 is larger than the outer diameter of the rotating body 20, the outer peripheral edge of the support plate 31 serves as a guide portion for preventing the fall of the game ball that is attracted to the outer peripheral surface of the rotating body 20 and conveyed. Function.

  A motor 32 for rotationally driving the rotating body 20 is fixed to one of the pair of support plates 31, and a pulley 33 is fixed to the output shaft of the motor 32. A pulley 34 is also fixed to the rotating shaft 20 a of the rotating body 20, and a belt 35 is wound around the pulley 33 and the pulley 34.

  When the motor 32 is driven to rotate, the rotation is transmitted to the rotating body 20 via the pulleys 33 and 34 and the belt 35, and the rotating body 20 rotates about the rotating shaft 20a.

  As shown in FIG. 4, the rotating body 20 includes a base drum 21 having a rotating shaft 20 a at the center of the shaft, and a magnet guide 22 that is disposed along the outer periphery of the base drum 21 and holds the magnetic body.

  The base drum 21 is a hollow cylindrical member in which both end openings of a cylindrical body portion 21a made of a soft magnetic material are closed. Thus, the outer peripheral part of the base drum 21 is comprised with a soft magnetic body. As the soft magnetic material, for example, ferritic stainless steel such as SUS430 is used.

  The magnet guide 22 is an elongated sheet-like member having a long side equivalent to the outer peripheral length of the base drum 21 and having flexibility, and is wound around the outer periphery of the base drum 21. The magnet guide 22 is made of rubber and is made of a nonmagnetic material.

  The magnet guide 22 may be made of a paramagnetic metal, synthetic resin, or ceramics as long as it is a non-magnetic material. In this case, if the magnet guide 22 is not flexible, it is formed in an annular shape. The base drum 21 is inserted into the outer periphery.

  In the magnet guide 22, a plurality of holding portions 22 a that hold the hard magnetic body 23 are formed through the upper and lower surfaces. The holding portion 22 a extends in the short direction of the magnet guide 22 and is formed at a predetermined interval in the longitudinal direction of the magnet guide 22.

  A plate-like hard magnetic body 23 is fitted exactly in each holding portion 22a. When the magnet guide 22 is wound around the outer periphery of the base drum 21, each hard magnetic body 23 extends in the direction of the rotating shaft 20 a and is disposed at a predetermined interval in the circumferential direction of the rotating body 20.

  A magnet cover 26 for preventing the hard magnetic body 23 from falling off is attached to the outer periphery of the magnet guide 22. The magnet cover 26 is a thin and long film having an inner peripheral surface coated with an adhesive such as glue.

  As a means for preventing the hard magnetic body 23 from falling off, a structure for locking the hard magnetic body 23 to the magnet guide 22 without using the magnet cover 26 may be provided.

  As described above, by arranging the magnet guide 22 holding the hard magnetic body 23 along the outer periphery of the base drum 21, the hard magnetic body is disposed on the outer peripheral edge of the rotating body 20 as shown in FIG. 23 is arranged at a predetermined interval in the circumferential direction of the rotating body 20, and a soft magnetic base drum 21 faces between the adjacent hard magnetic bodies 23 through a rubber magnet guide 22. As described above, the hard magnetic body 23 and the soft magnetic body are alternately arranged in the circumferential direction of the rotating body 20 on the outer peripheral edge of the rotating body 20.

  In this specification, a hard magnetic material is a magnetic material that is difficult to magnetize even when an external magnetic field is applied, and that retains its residual magnetization strongly once magnetized, and includes a permanent magnet.

  The soft magnetic material refers to a magnetic material in which magnetization is easily aligned in the magnetic field direction with respect to an external magnetic field, and the retentive force of residual magnetization is small.

  A non-magnetic material means a material that does not interact with a magnetic field.

  The transport device 12 is arranged over the first supply rod 10 and the rotating body 20 and rolls the first supply rod 10 to guide the game ball discharged from the downstream end portion 10 b to the rotating body 20. And a discharge guide 42 that is disposed between the rotating body 20 and the second supply rod 11 and guides the game ball conveyed by the rotating body 20 to the second supply rod 11.

  The supply guide 41 is formed in a U-shape comprising a rolling surface 41a on which the game ball rolls and a guide wall 41b provided on both sides of the rolling surface 41a to prevent the game ball from falling. It is a member and is composed of a non-magnetic material.

  The first supply rod 10 is communicated with the supply guide 41 by inserting the downstream end 10 b into the supply guide 41.

  The rolling surface 41a of the supply guide 41 has a larger inclination than the rolling surface 10c on which the game ball of the first supply basket 10 rolls.

  The first replenishing rod 10 and the supply guide 41 are connected to each other with a step 43 having a rolling surface 10c and a rolling surface 41a equal to or more than one gaming ball. That is, a step 43 equal to or more than one game ball is provided between the downstream end portion 10 b of the first supply rod 10 and the rolling surface 41 a of the supply guide 41. As a result, the game ball discharged from the downstream end portion 10 b of the first supply rod 10 falls down the step 43 and is guided to the rolling surface 41 a of the supply guide 41.

  The downstream side of the rolling surface 41a of the supply guide 41 faces the outer peripheral surface of the rotating body 20 with a gap through which the game ball cannot pass. As a result, only foreign matters such as dust guided to the supply guide 41 pass between the rolling surface 41a and the outer peripheral surface of the rotating body 20, so that the game ball rolling on the supply guide 41 is prevented from falling. The foreign matter guided to the supply guide 41 can be collected.

  The discharge guide 42 is disposed in the guide member 44 and a U-shaped guide member 44 that is provided standing on both sides of the bottom portion 44 a and a guide wall 44 b for preventing the game ball from dropping. And a guide plate 45 that guides the game ball adsorbed on the outer peripheral surface of the rotating body 20 to the second supply rod 11. The guide member 44 and the guide plate 45 are made of a nonmagnetic material.

  The second supply rod 11 communicates with the guide member 44 by inserting the upstream end portion 11 a into the guide member 44. Further, the guide plate 45 communicates with the second supply rod 11 by inserting the downstream end portion 45 c into the second supply rod 11.

  The rolling surface 45a of the guide plate 45 is larger in inclination than the rolling surface 11c on which the game ball of the second supply basket 11 rolls.

  At the upstream end of the rolling surface 45 a of the guide plate 45, a cylindrical guide rod 45 b is formed that is engaged with the end of the bottom 44 a of the guide member 44 and that is in sliding contact with the outer peripheral surface of the rotating body 20. .

  The guide rod 45b is formed over the entire width direction of the outer peripheral surface of the rotating body 20.

  As the rotating body 20 rotates, the outer peripheral surface of the rotating body 20 and the guide rod 45b are in sliding contact with each other. However, since the outer peripheral shape of the guide rod 45b is circular, the friction generated between the two is small.

  The game balls that are attracted to and transported by the outer peripheral surface of the rotating body 20 are guided away from the outer peripheral surface of the rotating body 20 to the rolling surface 45a of the guide plate 45 by contacting the guide rod 45b. Since the outer peripheral shape of the guide rod 45b is circular, the game ball adsorbed on the outer peripheral surface of the rotating body 20 is smoothly guided to the guide plate 45 along the outer peripheral shape of the guide rod 45b.

  A downstream end 45 c of the rolling surface 45 a of the guide plate 45 is connected to the rolling surface 11 c of the second supply rod 11. For this reason, the game ball rolling on the guide plate 45 is smoothly guided to the second supply rod 11. Instead of the guide plate 45, a gum tape may be applied across the bottom 44a of the guide member 44 and the rolling surface 11c of the second supply rod 11, and both may be smoothly connected via the gum tape.

  As described above, the first supply rod 10 and the second supply rod 11 are disposed such that the upstream end portion 11a of the second supply rod 11 is higher than the downstream end portion 10b of the first supply rod 10. The game ball guided from the first supply rod 10 to the rotating body 20 through the supply guide 41 is attracted to the outer peripheral surface of the rotating body 20 by magnetic force, and is connected to the second supply rod 11 by the rotation of the rotating body 20. 42 is conveyed.

  By the way, when there are few operation | movement of the game machine arrange | positioned at the game island 100, the game ball in the game ball supply apparatus 1 may increase and may become excessive. As a countermeasure, an overflow sensor 47 for detecting a state in which the second supply rod 11 is filled with game balls is disposed near the upstream end of the second supply rod 11. When the gaming machine is filled with the game ball from the downstream side of the second supply rod 11 and the game ball is filled to the position where the overflow sensor 47 is disposed, the game machine is mounted on the game island 100 from the overflow sensor 47. A signal is output to the transport control device (not shown), and the transport control device outputs a stop command to the motor 32 to stop the rotation of the rotating body 20. Thereby, since the operation of the transport device 12 is stopped, the transport of the game ball from the first supply rod 10 to the second supply rod 11 is stopped, and the game ball in the second supply rod 11 is prevented from overflowing. The

  Next, the operation of the game ball supply device 1 will be described mainly with reference to FIGS. 3 and 5 to 8. FIG. 5 is a diagram illustrating a process in which a game ball is transported by the transport device 12, FIG. 6 is a diagram illustrating a comparative example of FIG. 5, and FIG. FIG. 8 is a diagram showing a comparative example of FIG. 7.

  The game balls that have rolled the first supply basket 10 and have not flowed into any supply chute 13 are rotated from the first supply basket 10 through the supply guide 41 as shown in FIGS. 5 (a) and 5 (b). Guided to the body 20.

  Here, since the rolling surface 41 a of the supply guide 41 has a larger inclination than the rolling surface 10 c of the first supply rod 10, the game ball rolls vigorously on the rolling surface 41 a of the supply guide 41. . Therefore, as shown in FIG. 5 (b), even if game balls are in a continuous state on the rolling surface 41a, the game balls discharged to the supply guide 41 after that ride on the continuous game balls. Therefore, since it rolls on the game ball, it can easily reach the vicinity of the outer peripheral surface of the rotating body 20.

  On the other hand, as shown in FIG. 6A, when the inclination of the rolling surface 41a of the supply guide 41 is equal to or smaller than the inclination of the rolling surface 10c of the first supply rod 10, Since the momentum of the game balls rolling on the supply guide 41 is weak, the game balls discharged to the supply guide 41 later cannot roll on the connected game balls and are supplied to the first supply rod 10. It accumulates in the vicinity of the connecting portion of the guide 41 and hardly reaches the outer peripheral surface of the rotating body 20.

  Further, since a step 43 equal to or more than one game ball is provided between the downstream end portion 10b of the first supply rod 10 and the rolling surface 41a of the supply guide 41, as shown in FIG. Even if the game balls are connected to the rolling surface 41a, the game balls discharged to the supply guide 41 later are discharged onto the connected game balls. It is easy to reach the vicinity.

  On the other hand, as shown in FIG. 6B, there is no step between the downstream end portion 10b of the first supply rod 10 and the rolling surface 41a of the supply guide 41, and both are smoothly communicating. In such a case, it is difficult for the game balls to be stacked, so that it is difficult to reach the outer peripheral surface of the rotating body 20.

  As described above, by increasing the inclination of the supply guide 41 and providing a step between the supply guide 41 and the first supply rod 10, as shown in FIG. The sphere can be caused to flow into a region that is easily influenced by the magnetic field surrounded by the rolling surface 41 a of the supply guide 41 and the outer peripheral surface of the rotating body 20. As a result, the number of game balls in the vicinity of the outer peripheral surface of the rotator 20 increases, so that the game balls are easily attracted to the outer peripheral surface of the rotator 20 by the action of the magnetic field.

  The game ball that has reached the vicinity of the outer peripheral surface of the rotating body 20 by the supply guide 41 is attracted to the hard magnetic body 23 by the magnetic field exerted by the hard magnetic body 23 disposed on the outer peripheral edge of the rotating body 20.

  Since the game ball attracted to the hard magnetic body 23 is magnetized, another game ball is attracted and magnetized by the magnetized game ball. In this way, the game balls are adsorbed in a bead shape as shown in FIG.

  Further, since the game balls adsorbed in a bead shape are magnetized, the body portion 21a of the base drum 21 which is a soft magnetic material is also magnetized by the magnetic field of these game balls. As a result, the game balls adsorbed in a bead shape are attracted to the body portion 21 a of the base drum 21 with the magnet guide 22 and the magnet cover 26 therebetween. Since the magnetic circuit is formed on the outer peripheral edge of the rotating body 20 by the hard magnetic body 23, the game ball adsorbed in a bead shape, and the body portion 21a of the soft magnetic body in this way, FIG. As shown in FIG. 7, the game ball is adsorbed in a rosary shape on the outer peripheral surface of the rotating body 20 with each hard magnetic body 23 as a base point.

  Here, if the body portion 21a of the base drum 21 is a non-magnetic material, the body portion 21a is not magnetized, so that no magnetic circuit is formed on the outer peripheral edge of the rotating body 20. In this case, as shown in FIG. 8, the game ball is adsorbed in a rosary shape with the hard magnetic body 23 as a starting point, but is not adsorbed on the outer peripheral surface of the rotating body 20 and is hung vertically downward by gravity. It becomes a state. Therefore, there is a limit to the number of game balls that are adsorbed in a bead shape, and many game balls cannot be transported. Moreover, since it falls depending on the weight of a game ball, a game ball cannot be conveyed efficiently.

  Further, if the supply guide 41 is a soft magnetic body, when the game ball in the supply guide 41 is attracted to the hard magnetic body 23, the hard magnetic body 23, the game ball in the supply guide 41, and the supply guide At 41, a magnetic circuit is constructed. For this reason, as shown in FIG. 6C, the game balls are connected over the hard magnetic body 23 and the supply guide 41, and the game balls are not efficiently attracted to the outer peripheral surface of the rotating body 20. For this reason, the supply guide 41 being a non-magnetic material is a requirement for efficiently transporting game balls. The supply guide 41 is made of, for example, austenitic stainless steel such as SUS304.

  If the supply guide 41 is made of a non-magnetic material, the rotating body 20 and the first supply rod 10 are separated by the non-magnetic material, so that a magnetic field is applied to the game ball rolling on the first supply rod 10. And it becomes a difficult structure. Therefore, the first replenishing rod 10 has no restrictions on material selection and can be freely selected from the viewpoint of cost. For example, it is cheaper than SUS304, and can also be composed of SUS430, which is a soft magnetic material.

  The game balls adsorbed in a rosary shape on the outer peripheral surface of the rotating body 20 are conveyed along with the rotation of the rotating body 20, and as shown in FIG. By coming into contact with the guide rod 45 b, it is guided away from the outer peripheral surface of the rotating body 20 to the rolling surface 45 a of the guide plate 45 and flows into the second supply rod 11. In this way, the game balls discharged from the downstream end portion 10 b of the first supply rod 10 are conveyed to the upstream end portion 11 a of the second supply rod 11.

  According to the above embodiment, the following operational effects are obtained.

  A magnetic circuit is formed on the outer peripheral edge of the rotating body 20 by the hard magnetic body 23, the game ball adsorbed on the hard magnetic body 23, and the soft magnetic body. Adsorbs in a rosary shape.

  As described above, the game ball supply device 1 is configured to attract and transport the game ball to the outer peripheral surface of the rotary body 20 by the magnetic force of the magnetic body disposed on the outer peripheral edge of the rotary body 20. The transport path is not structured to be transported from a wide space to a narrow space. Moreover, it is not necessary to provide the rotating body 20 with a member for transporting the game ball. Therefore, there is no risk of ball clogging, and game balls can be supplied to the gaming machine stably. Moreover, the rotary body 20 can be made into a simple structure.

  Further, since the hard magnetic body 23 and the soft magnetic body constituting the magnetic circuit with the game ball are provided, it is sufficient that the hard magnetic body 23 is disposed at a predetermined interval in the circumferential direction of the rotating body 20. Since it is not necessary to arrange in the whole, cost can be reduced.

  Next, another embodiment of the present embodiment will be described.

(1) As shown in FIG. 9, it is desirable to arrange adjacent hard magnetic bodies 23 so that the S pole and the N pole face each other. By disposing the hard magnetic body 23 in this manner, the game balls are attracted over the adjacent hard magnetic bodies 23, so that more game balls can be attracted to the outer peripheral surface of the rotating body 20. Therefore, the transport efficiency of game balls is improved.

(2) Although FIG. 9 shows the hard magnetic body 23 in which the N pole and the S pole are magnetized in the circumferential direction of the rotating body 20, as shown in FIG. Even when the hard magnetic material 23 with the S pole magnetized is used, the same effect as the effect (1) is obtained.

(3) In the above embodiment, the hard magnetic body 23 is held by the rubber magnet guide 22, and the body portion 21a of the base drum 21 is a soft magnetic body. Instead, as shown in FIG. 11, the magnet guide 22 itself is formed of an annular soft magnetic material, and the magnet guide 22 is inserted into the outer periphery of the base drum 21 so as to be integrated with the base drum 21. May be.

  If comprised in this way, since the hard magnetic body 23 and the soft magnetic body will be alternately arrange | positioned by the circumferential direction on the outer peripheral surface of the magnet guide 22, it will become easy for the magnetic force of a soft magnetic body to act on a game ball, and a game The sphere is easily adsorbed to the outer peripheral surface of the rotating body 20.

  The present invention is not limited to the above-described embodiment, and it is obvious that various modifications can be made within the scope of the technical idea.

  The game ball supply device of the present invention can be applied as a device for supplying game balls to game machines. Note that the gaming machine is not limited to the pachinko gaming machine as shown in the above embodiment, and for example, other pachinko gaming machines, arrange ball gaming machines, sparrow ball gaming machines, slot machines and the like.
