Description

  The present invention relates to a ball polishing apparatus for gaming machines, and more particularly to a ball polishing apparatus that is built in a gaming machine that uses pachinko balls and that polishes and cleans dirty pachinko balls.

  In gaming machines that use pachinko balls, the surface of the pachinko balls is likely to be contaminated with hand grease, dust in the hall, tobacco smoke components, or equipment-derived oil or dust. It is known that pachinko spheres are clogged in the circulation path due to the influence of various stains and affect the behavior of pachinko spheres.

  For this reason, dirty pachinko balls from a plurality of gaming machines are collected in one place, collectively cleaned with a large ball polisher, and returned to each gaming machine. However, in order to place a large ball polisher at a position away from each gaming machine and transport the pachinko balls between them, the extra installation space and a large amount of driving power are required. Therefore, it is easy to lead to worsening the cost performance of the amusement hall.

  Therefore, as described in, for example, Japanese Patent Application Laid-Open No. 2008-6092 and Japanese Patent Application Laid-Open No. 2012-179143, each game machine is equipped with a ball polishing device that polishes and cleans pachinko balls. became. In such an interior-type ball polishing device, the pachinko balls collected in the ball reservoir are sequentially transported by a spiral-type or vertically-rotating sprocket-type ball feed rotating body that rotates around the axis, and are attached to the ball transport path. A method of cleaning by cleaning with a member (abrasive) is employed, and the installation space and power consumption cost can be reduced as compared with the case of cleaning at one place as described above.

  However, with such an interior-type ball polishing device, it is necessary to align the pachinko balls in a row before transporting with the ball feed rotating body, and the inflow of the pachinko balls is not smoothly performed in the aligned portion. Since there are many cases where the carrying capacity is limited due to the occurrence of clogging or clogging, there is a possibility that the processing capacity cannot be caught up in a gaming machine with a high ball rotation rate in recent years.

  On the other hand, as described in Japanese Patent Application Laid-Open No. 2007-151735, a sprocket-like ball feed rotating body is provided so as to be laterally rotated below the ball storage portion in the gaming machine, and a concave portion continuously provided on the outer peripheral side thereof. A ball feed rotating body that rotates while holding a pachinko ball and sends it to a discharge port is also known, and it is conceivable to apply this method to the above-described ball polisher for gaming machines to realize high processing capability.

  However, even when the sprocket-like ball feed rotator is horizontally placed and transported in this way, the pachinko ball forms a bridge on the introduction side to the ball feed rotator and the transport stops or the ball is stored. In some cases, pachinko balls are biased within the unit, which may prevent introduction into the ball-feed rotating body, so that it is not easy to always maintain a high processing capacity. In addition, even if a method of cleaning while feeding a pachinko ball with a horizontally rotating ball feed rotating body is adopted, a method for efficiently removing dirt with a cleaning member itself has not been developed yet, so an excellent cleaning (polishing) function is provided. It is difficult to realize.

  The present invention is intended to solve the above-described problems, and it is an object of the present invention to achieve an excellent cleaning function with a high processing capacity for a ball polishing apparatus for gaming machines installed in individual gaming machines. And

  Therefore, the present invention is arranged at a predetermined position in a gaming machine using a pachinko ball, and is arranged so as to rotate laterally by a motor drive on the bottom surface side of the ball storage portion and storing the pachinko ball. A sprocket-like ball feed rotating body that holds the pachinko balls in the recesses continuously provided on the side and sends them in the circumferential direction, and a cleaning member that removes dirt from the pachinko balls, and the pachinko balls stored in the ball storage section In a ball polisher for a gaming machine that performs cleaning by sliding it in contact with the cleaning member while sequentially transporting the balls in the circumferential direction, the ball feeding rotator protrudes from the center side to the outer peripheral side with the upper surface center portion protruding. A downward inclined surface is formed, the cleaning member is disposed below the ball feed rotator, and a predetermined position on the upper surface is a cleaning line along a ball transport path by the ball feed rotator. It constitutes a face, and shall be characterized in that.

  In this way, the center part of the upper surface of the sprocket-shaped ball feed rotating body protrudes to form a downwardly inclined surface toward the outer peripheral side, so that the rotation of the pachinko ball group placed on the upper surface by the rotation is disrupted while collapsing on the downwardly inclined surface. Since it acts to guide in the direction, it is easy to eliminate pachinko ball bridges and bias, ensuring high processing capacity by smooth conveyance, and cleaning surface along the conveyance path of pachinko balls sent in the circumferential direction Since the cleaning member is arranged below the ball feed rotator so as to constitute the cleaning, it becomes possible to carry out cleaning in a relatively long C-shaped stroke, so that an excellent cleaning function is realized and the pachinko ball is efficiently used. Can be beautiful.

  Further, in this ball polishing device, the ball feed rotating body is formed with ribs by ridges extending in the centrifugal direction from the center side on the downward inclined surface, and a group of pachinko balls is placed on the downward inclined surface. By rotating in a state, the pachinko ball is stirred while the step due to the rib is moved and the bottom side of the group is vibrated and collapsed. The unevenness is surely eliminated and smoother conveyance can be secured.

  Furthermore, in the above-described ball polishing apparatus for gaming machines, the ball feed rotating body is inserted into a rotating body storage portion opened in a substantially circular shape in plan view on the upper surface side of the main body case, and the outer peripheral side and the rotating body are inserted. A ball transport path is formed between the inner peripheral surface of the storage portion, and a boss having a predetermined shape is provided at a predetermined position on the inner peripheral surface so as to be in contact with the side surface of the pachinko ball being transported and to laterally rotate the pachinko ball. If it is characterized in that it is projected with a predetermined width, the phase of the pachinko sphere that is conveyed in the circumferential direction and rolls in a substantially vertical rotation can be changed by applying a lateral rotation by the contact of the boss. It becomes easy to eliminate the unevenness of the cleaning site on the sphere surface.

  Furthermore, in the above-described ball polishing apparatus for gaming machines, the ball feed rotator has a cleaning surface provided with a predetermined cleaning member at a predetermined position on the descending inclined surface, and the ball feed rotator comprises If the pachinko ball placed on the cleaning surface is cleaned by rotation, the cleaning member having a further excellent cleaning function and constituting a part of the downward inclined surface is provided. The frictional force between the surface and the pachinko sphere further facilitates the elimination of bridges and bias.

  In this case, the ball feed rotating body is characterized in that the protruding portion having the cleaning surface is separated from the portion having the gear shape on the lower side and is removable. As a result, only the protruding portion of the ball-feed rotating body whose cleaning surface has become dirty due to use and the cleaning function has deteriorated can be replaced and used.

  In addition, in the above-described ball polishing apparatus for gaming machines, the ball feed rotator is pivotally mounted with the motor drive shaft protruding from the lower side being eccentric, and the trajectory of the circumferential ball transport path is thereby If it varies according to the position of the recess holding the pachinko ball, it is efficient while using a different part of the cleaning member as a cleaning surface according to the position of the recess holding the pachinko ball. In addition to being able to realize cleaning, the upwardly projecting portion rotates while being eccentric, so that the stirring ability of the pachinko sphere is excellent, and further smooth conveyance can be ensured.

  According to the present invention in which the upper surface side of the laterally rotating ball feed rotating body is protruded to form the downward inclined surface, an excellent cleaning function can be realized with high processing capability.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

  FIG. 1 shows a ball polisher 1 for a gaming machine according to an embodiment of the present invention. This gaming machine ball polishing device 1 is a device that is disposed at a predetermined position in a ball passage inside a pachinko machine and polishes and cleans dirty pachinko balls, and includes a storage case 2 in which a ball storage unit 20 is formed. A main body case 4A provided on the bottom surface side, a substantially disk-shaped ball feed rotating body 3A horizontally disposed in the main body case 4A so as to be rotated by driving of the motor 6, and a ball formed by the ball feeding rotating body 3A A flat plate-like cleaning member 50A is provided along with the conveyance path to remove dirt on pachinko balls being conveyed.

  As shown in the exploded perspective partial view of FIG. 2, the ball feed rotating body 3A is inserted on the inner peripheral side of the rotating body storage portion 42A that is opened circularly on the upper surface side of the main body case 4A. The drive shaft 6a is configured such that the outer peripheral surface formed with the concave portion 30a rotates laterally at a predetermined speed while maintaining a predetermined interval with the peripheral wall 42a constituting the inner peripheral surface of the rotating body storage portion 42A. It is supported by.

  In other words, the ball feed rotating body 3A is a resin molded product formed in a single boss type sprocket shape having a plurality of recesses 30a on the outer peripheral side, and the central portion on the upper surface of the gear-shaped portion 30A which is the lower portion thereof. The conical part 31A of the upper part is configured by forming a downward inclined surface that protrudes in a conical shape and extends from the center side toward the outer peripheral side, and the spherical storage part 20 is formed in each concave part 30a on the outer peripheral side of the gear-like part 30A. The pachinko balls that are held by falling and entering are conveyed in the circumferential direction.

  Then, a flat plate-like cleaning member is provided in the main body case 4A below the ball feed rotator 3A so as to form a cleaning surface along a C-shaped (arc-shaped) sphere conveying path in plan view by the ball feed rotator 3A. 50A is arranged horizontally, and the pachinko ball is cleaned by being brought into sliding contact with the cleaning surface on the upper surface of the cleaning member 50A while being transported by the ball feed rotating body 3A, and then dropped onto the ball feed rail 7 from the delivery port 41a. It is supposed to be sent out.

  A plurality of semi-cylindrical bosses 420 are arranged at predetermined intervals in the circumferential direction at predetermined positions on the inner peripheral surface of the peripheral wall 42a in the rotating body storage portion 42A. The tip side surface of each boss 420 is in contact with the side surface of the pachinko ball conveyed by the ball feed rotator 3A, so that it is laterally rotated.

  FIG. 3 shows an exploded perspective view of the ball polishing apparatus 1 for gaming machines. The main body case 4A includes an upper case 40 having a rotating body housing portion 42A and a lower case having a delivery port 41, and a drawer plate 45 on which a cleaning member 50A is placed through an opening formed on the side surface thereof. It is built in such a state that it can be inserted and removed from the side, and the replacement work of the cleaning member 50A can be easily performed.

  The cleaning member 50A using a predetermined portion on the upper surface as the cleaning surface 50a is preferably a fiber assembly such as a nonwoven fabric in which fibers are hardened in a flat plate shape, but both surfaces can be used by turning it over. Is preferred. The cleaning member 50A and the drawer plate 45 on which the cleaning member 50A is placed have notches 45a and 50b from one side toward the center so that the drive shaft 6a of the motor 6 does not interfere during the insertion / removal operation. Has been.

  FIG. 4 shows a plan view of the above-described ball polishing apparatus 1 for gaming machines, and the ball storage unit 20 has a slight downward slope toward the central part, and the lowest central part. Is formed with an opening 20a having an inner diameter slightly smaller than the outer diameter at a position coinciding with the ball feed rotator 3A, and the stored pachinko balls are gathered in the opening 20a and are placed on the ball feed rotator 3A. It is easy to put. Further, a part of the opening 20a is extended in the centrifugal direction of the ball feed rotator 3A to form a ball drop mouth 200, and a recess of the ball feed rotator 3A is dropped while a pachinko ball is dropped from the ball drop mouth 200. It is introduced and held in 30a.

  Next, the function of the present embodiment will be described in detail with reference to FIG. 4 described above and FIG. 5 showing the state of use in a longitudinal section.

  In this gaming machine ball polishing apparatus 1, as shown in FIG. 5, a ball feeding rotating body 3A in which a large number of pachinko balls 100 are introduced and stored in the ball storage section 20 and exposed to the opening 20a on the bottom surface side. Many pachinko balls 100 are also placed on the upper surface of the conical portion 31A. From the lower layer side of the group of pachinko balls 100 stacked in this manner, the pachinko balls 100 enter and be held in the recess 30a of the ball feed rotating body 3A through the ball drop opening 200, and this is rotated laterally by driving the motor 6. It is conveyed in the circumferential direction by the ball feed rotating body 3A.

  During the conveyance, the held pachinko ball 100 is sent from the position where it entered the concave portion 30a on the right side in the figure through the ball conveyance path in the plan view circumferential direction (left side in the figure), but below the ball feed rotating body 3A. On the upper surface of the cleaning member 50A disposed on the surface, the pachinko ball 100 rolls on the cleaning surface 50a (see FIG. 4) having a C-shape in plan view along the ball conveyance path and cleans the surface by rolling. Is done.

  Further, the conical portion 31A of the ball feed rotating body 3A has a downward inclined surface formed from the central side toward the outer peripheral side, so that the pachinko ball 100 placed thereon moves to the outer peripheral side by gravity. In combination with the rotation operation of the ball feed rotating body 3A, the group of pachinko balls 100 placed on the ball feeding rotary body 3A is broken and easily introduced into the ball drop opening 200.

  Further, as shown in FIG. 4, four ribs 31a extending in the centrifugal direction from the center side are formed on the downward inclined surface of the conical portion 31A, and the rib 31a is rotated by the rotation of the ball feed rotating body 3A. Since the step also rotates, it has a function of giving vibration to the bottom side of the group of pachinko balls 100 placed thereon. Therefore, the vibration acts to disperse the group of pachinko balls 100 while diffusing them, and it is easy to introduce the pachinko balls 100 into the ball drop opening 200 smoothly while eliminating the bridge and uneven distribution of the pachinko balls 100. High processing capacity exceeding 100 / min can be easily realized.

  In addition, as described above, a plurality of semi-cylindrical bosses 420 having a predetermined width projecting from the inner peripheral surface are disposed in the rotating body housing portion 42A of the main body case 4A in which the ball feeding rotating body 3A is disposed. 2 (see FIG. 2), the tip surface side functions to apply lateral rotation to the side surface of the pachinko ball 100 conveyed in the circumferential direction by the ball feed rotating body 3A.

  That is, since each pachinko ball 100 cleaned while rolling in the vertical direction on the cleaning surface 50a having a C-shape in plan view touches the boss 420 protruding from the inner peripheral surface, the phase in the rotational direction is displaced. The bias of the cleaning site on the surface of the pachinko ball 100 can be corrected, and it is easy to realize efficient cleaning.

  Therefore, by using this embodiment, it is possible to ensure high processing performance while exhibiting an excellent cleaning function for the stored pachinko sphere 100. In addition, although illustration is omitted, in the conical portion 31A of the ball feed rotating body 3A, a flat plate-like cleaning member is affixed to each downward inclined surface formed between the ribs 31a and 31a and placed thereon. A cleaning surface for the pachinko ball 100 may be formed, and thus cleaning is performed while the cleaning surface is in sliding contact with the pachinko ball 100 on which the cleaning surface is placed by a rotation operation accompanying the conveyance of the pachinko ball 100. A cleaning function can be realized.

  FIG. 6 shows a characteristic portion of an application example of the above-described ball polishing apparatus 1 for gaming machines. In this example, a rotating body formed by expanding the arrangement interval while using a semi-cylindrical boss 420 arranged on the inner peripheral side of the rotating body storage portion 42A of the main body case 4A as a boss 421 having an enlarged width in the circumferential direction. A ball feed rotating body having a main body case 4B provided with a storage portion 42B, and having a rear surface side in the rotation direction inclined rearward with respect to the shape of the projection on the outer peripheral side of the ball feeding rotating body 3A. It is characterized by 3B.

  Accordingly, the pachinko ball 100 is urged in the centrifugal direction by the inclined surface by the rotation of the ball feed rotating body 3B, and the pachinko ball 100 is placed on the outermost inner peripheral surface between the bosses 421 and 421. The boss 421 is advanced along the slope on the side end side at the position of the next boss 421 and then advances along the tip surface of the innermost boss 421. That is, the pachinko ball 100 advances in the circumferential direction while reciprocating in the centrifugal direction on the upper surface of the cleaning member 50A, and the phase in the rotation direction is further easily changed.

  FIG. 7 shows a characteristic part according to another application example of the above-described ball polishing apparatus 1 for gaming machines. In this example, the main body case 4C is provided with a rotating body storage portion 42C in which the inner diameter of the rotating body storage portion 42A of the main body case 4A is enlarged by about the radius of the pachinko ball 100 and the boss 420 is eliminated. The planar shape of the convex portion on the outer peripheral side of the rotating body 3B is characterized in that it is a ball-feed rotating body 3C that is tilted forward as the rear side in the rotational direction is directed toward the tip side to form a bowl shape.

  Thereby, the pachinko ball 100 held in the concave portion 30c of the ball feed rotating body 3C is held inside the bowl-shaped portion by the rotation. Further, in this example, the ball feed rotator 3C is connected with the drive shaft 6a of the motor 6 eccentrically by an amount corresponding to the radius of the pachinko ball 100, and the rotational trajectory on the outer peripheral side fluctuates due to the eccentricity. It is also a feature.

  That is, when this ball feed rotating body 3C is rotationally driven, a cleaning surface having different trajectories is used depending on the position where the pachinko ball 100 is held. For example, the pachinko ball 100 held at a position closest to the drive shaft 6a. And the pachinko ball 100 held at a position farthest from the drive shaft 6a, the diameter of the pachinko ball 100 is displaced in the trajectory of the ball transport path, so that a wider area is used on the upper surface of the cleaning member 50A. The cleaning member 50A can be used for a longer period.

  FIG. 8 shows a ball feed rotator 3D as an application example of the above-described ball feed rotator 3A. In this example, two separate parts, a main body part 30D having a connecting hole 300 formed in the central part of a part having the same shape as the ball feed rotator 3A, and an umbrella-shaped cleaning part 31B through which a prism 310 passes vertically. The ball feed rotating body 3D is configured, and the cleaning portion 31B can be freely attached to and detached from the main body 30 by fitting the lower portion of the prism 310 into the connecting hole 300 of the main body 30D. It is characterized by.

  The cleaning part 31B is formed by attaching a cleaning member 50B made of a nonwoven fabric or the like to the inclined upper surface of the base 312 formed of resin in an umbrella shape or by insert molding, and rotates the ball feed rotating body 3D to rotate the pachinko. When the sphere 100 is transported, in addition to exhibiting a function of cleaning the pachinko sphere 100 placed on the cleaning member 50B while sliding on the surface, the sphere 100 is placed on the surface by a large frictional force by the cleaning member 50B. It also has an excellent function of diffusing the pachinko sphere 100 while breaking it.

  Needless to say, the cleaning unit 31B having such a configuration can be similarly applied to the above-described ball feed rotators 3B and 3C, and exhibits the same function. For example, when applied to the ball feed rotating body 3C of FIG. 7, the prism 310 protruding upward from the cleaning unit 31B due to its eccentric function oscillates in the horizontal direction while rotating in the group of pachinko balls 100. , It will be more excellent in eliminating the group and bias of the pachinko balls 100.

  On the other hand, instead of sticking the cleaning member 50B made of the above-described nonwoven fabric or the like, when the predetermined cleaning member is molded into a ball feed rotating body or a detachable cleaning part, the protrusion of the ball feeding rotating body described above by insert molding is used. It may be molded integrally with the upper surface side of the part or the above-mentioned umbrella-shaped base upper surface side, or these are exposed to the upper surface side while kneading the powder or short fiber cleaning member components into a predetermined resin. However, it may be prepared as a single resin molded product.

  As described above, according to the present invention, an excellent cleaning function can be realized with a high processing capacity for a ball polishing apparatus for gaming machines installed in individual gaming machines.
