JP-A-5-237255 Japanese Patent No. 2518490

  According to the technique of Patent Document 1, it is necessary to incline the collection basket and the conveyance basket in order to convey the pachinko balls. As a result, pachinko islands become expensive, and the pachinko islands become larger, the crime prevention due to poor visibility in the amusement store, the aesthetics, and the in-store environment such as lighting and ventilation deteriorate. According to Patent Document 2, although the problem of Patent Document 1 can be solved, since one belt conveyor is arranged over the entire length of Pachinko Island as a conveying means, due to belt cutting or failure of the driving device, If pachinko balls cannot be transported by the belt conveyor, the pachinko ball replenishment function of the entire pachinko island will stop. In particular, in Pachinko Island, it is necessary to always supply pachinko balls to pay out prize balls and rental balls. It must be a big loss. Furthermore, since the belt conveyor covering the entire length of the pachinko island is used, it becomes difficult to change the length of the pachinko island and cope with the curved island. In addition, not only pachinko balls but also other spheres, such as ball bearing balls, are transported in factories, etc., it is necessary to stop the devices arranged along the belt conveyor by stopping the belt conveyor. There is a problem that it is not easy to change the line.

  It is an object of the present invention to provide a sphere transport apparatus that does not stop the entire transport even if a failure occurs in part when transporting a sphere.

  The sphere conveyance device of one embodiment of the present invention conveys a large number of spheres in the horizontal direction. As the sphere, pachinko balls or ball bearing balls can be used. This sphere conveying device has a conveying rod, and each sphere placed on the conveying rod rolls to move substantially in the horizontal direction. This conveyance rod can have a conveyance surface and a side wall provided on the side of the conveyance surface along the conveyance direction on the conveyance surface. Side walls can also be provided on both sides of the transport surface. At least a part of the upper surface of the conveying member is movably provided at a protruding position protruding from the conveying surface of the conveying rod and a non-projecting position below the conveying surface, and at the protruding position, the upper surface of the spherical body The posture is inclined downward in the transport direction, for example, toward the downstream side. A plurality of conveying members are provided. The plurality of transport members are desirably provided at least in the transport direction. The driving means moves the conveying member between the protruding position and the protruding position. When the conveying member is in the protruding position, the sphere placed on the upper surface rolls in the inclined direction of the upper surface, whereby the sphere is conveyed.

  In the sphere conveying apparatus configured as described above, when each conveying member is in the non-projecting position, each sphere is placed on the upper surface, and when each conveying member moves to the projecting position, the sphere on the upper surface is inclined to the upper surface. It rolls in the direction, that is, the conveyance direction, and is conveyed. In this case, the transport rod is arranged so that the sphere rolls almost horizontally, and is not greatly inclined downward in the transport direction. Therefore, the sphere transport device does not increase in size. Moreover, even if any one of the transport members becomes unmovable between the projecting position and the non-projecting position for some reason, the other transport members move between the projecting position and the non-projecting position. The movement never stops.

  A discharge port for each of the spheres can be provided on the side of the transport rod so that the sphere on the transport rod can enter. The discharge port can also be provided on the side wall of the conveying basket. It is also possible to arrange a plurality of discharge ports at intervals in the length direction of the conveying rod. The outlet is preferably in communication with a device that uses a sphere.

  If comprised in this way, the spherical body which reached | attained the discharge port will be discharged | emitted from a discharge port, and it will be supplied to the apparatus using a sphere, while the sphere is rolling on the conveyance rod.

  At least a part of the conveying surface of the conveying rod can be an inclined surface that is inclined downward toward the conveying member. For example, when the conveying member is arranged in an opening formed on the conveying surface and moves between a protruding position and a non-protruding position, a slope inclined downward toward the conveying member is formed at the periphery of the opening. Can do.

  If comprised in this way, the spherical body on a conveyance surface will roll on a slope, and it will gather efficiently in the vicinity of a conveyance member, and can convey the spherical body by a conveyance member favorably.

  At least a part of the conveying surface of the conveying rod may be an inclined surface that is inclined downward toward the discharge port. When the discharge ports are arranged on both sides of the conveyance basket along the conveyance direction of the conveyance basket, the central portion of the conveyance surface of the conveyance basket is the highest, and the conveyance surface may be inclined obliquely downward toward both sides. it can.

  If comprised in this way, the spherical body on a conveyance surface will roll automatically to the discharge port side, and branch discharge of a spherical body will be performed efficiently.

  The main part of the transport member may be columnar. For example, it can be a columnar shape or a prismatic shape. An inclined surface inclined downward in the conveying direction of the sphere is formed on the upper surface of the main part. An opening in which the conveying member is disposed is formed on the conveying surface of the conveying rod. A gap smaller than the diameter of the sphere is formed between the opening and the conveying member. The peripheral portion of the opening may be an inclined surface that surrounds the peripheral edge of the transport member and is inclined downward toward the inner side of the transport member outside the peripheral edge of the transport member. Driving means reciprocates the transport member between the protruding position and the non-projecting position. It is desirable to provide a sleeve portion that surrounds these openings and extends below the conveying surface.

  If comprised in this way, when a conveyance member exists in a non-projecting position, a spherical body will enter into opening and it will be mounted on the upper surface of a conveyance member. And if a conveyance member moves to a protrusion position, as mentioned above, each spherical body will roll on the upper surface of a conveyance member, and will be conveyed. Since the openings are provided in this way, each sphere is efficiently placed on the upper surface of the conveying member, and the sphere is efficiently conveyed. In addition, since the driving means reciprocates, the sphere is repeatedly placed on the upper surface and rolled from the upper surface, further improving the efficiency of conveying the sphere.

  An opening in which the transport member is disposed may be formed on the transport surface of the transport rod. It is desirable that a gap smaller than the diameter of the sphere is formed between the opening and the transport member. The conveying member has an axis that crosses the conveying surface at a position downstream of the opening, and is swingable around the axis so as to pass through the protruding position and the non-projecting position. In the position, the upper surface of the conveying member is formed as an inclined surface inclined downward toward the downstream side. The drive means reciprocates the transport member between the projecting position and the non-projecting position.

  If comprised in this way, a spherical body will be conveyed efficiently according to the rocking | fluctuation between the protrusion position and non-protrusion position of a conveyance member.

  The conveying member may have a spherical escape surface on the upstream side for moving the spherical body from the upstream side to the downstream side. In this configuration, since the sphere on the upstream side of the transport member can move to the downstream side through the escape surface in a state where the transport member is in the projecting position, the transport member in the projecting position can move the upstream side thereof. It is possible to efficiently transport the sphere without preventing the rolling of the sphere on the side.

  A plurality of the driving means may be provided. In this case, each driving means drives one or a plurality of conveying members. When configured in this way, if any of the drive means fails, the transport member driven by the failed drive means cannot move between the protruding position and the non-projecting position. The driven conveying member can move between a protruding position and a non-projecting position. Therefore, the sphere cannot be transported by the entire sphere transport device, and the sphere is continuously transported.

  The transport basket can be configured by connecting a plurality of delivery basket units. If comprised in this way, in this case, it is desirable for each conveyance rod unit to be provided with at least one conveyance member. When the transport rod unit is used in this way, it is possible to easily configure a change in the length of the transport route or a bent transport route by adjusting the connection method of the transport rod units.

  The plurality of conveying members can be installed at a plurality of positions at different distances from the side of the conveying rod. If comprised in this way, even if the movement of one of the conveyance members becomes impossible for some reason, the conveyance device bypasses the immovable conveyance member and the space where the sphere is conveyed is on the conveyance surface. The transportation of the sphere as a whole does not stop.

  As described above, according to the present invention, even when a sphere is transported, even if a failure occurs in part, the entire transport is not stopped, and the height of the transport device can be kept low.

  The conveying apparatus of 1st Embodiment of this invention is implemented on the pachinko island 1 as shown in FIG. A plurality of pachinko machines 2 are arranged side by side on the pachinko island 1. Pachinko balls used for games in each pachinko machine 2 are discharged from the pachinko machine 2 and conveyed to the lower part of the lifting device 4 by the collecting device 3 provided at the lower part of the pachinko island 1. The collection device 3 is a gutter provided to be inclined obliquely downward from the left island end to the right island end in FIG. The lifting device 4 is provided at the right end of the pachinko island in FIG. 1 and is a lift provided with a pachinko ball polishing function. The lifting device 4 lifts the pachinko balls to the upper part of the pachinko island 1 while polishing the pachinko balls. The lifted pachinko balls are supplied to the supply device 5 via the supply chute 6. In FIG. 1, only one side of the pachinko island 1 is shown, but the pachinko machine 2 is similarly arranged on the opposite side.

  The replenishing device 5 is arranged almost horizontally, and the pachinko balls on the both sides of the pachinko island 1 are transported from the upstream side, for example, the right side of FIG. 1 to the downstream side, for example, the left side of the island. Supply machine 2 with pachinko balls. The pachinko ball that has reached the left island end of the replenishing device 5 is returned to the collecting device 3 by the overflow unit 7.

  In addition, the upper discharge port of the lifting device 4 is provided at a position slightly higher than the replenishing device 5, and the replenishing chute 6 is inclined downward toward the replenishing device 5, so that each pachinko ball supplied to the replenishing device 5 is slightly It is desirable to apply the propulsive force in order to smoothly transport the pachinko balls on the replenishing device 5.

  As a transport device of the replenishing device 5, a transport device 10 according to an embodiment of the present invention is provided. As shown in FIG. 2, the transport apparatus 10 includes a transport basket, for example, a bowl-shaped transport apparatus main body 11. The main body 11 has a conveyance surface, for example, a bottom wall 12 and a side wall 13. The bottom wall 12 is disposed substantially horizontally along the length direction of the pachinko island 1, and side walls 13 and 13 are formed along both longitudinal edges thereof. As shown in FIG. 4A, the bottom wall 12 is inclined downward toward the side walls 13 and 13 with the center in the width direction as a vertex. That is, the bottom wall 12 has an inverted V shape.

  On both sides of the conveying device 10, side walls 13 are bulged outwardly, and spherical discharge ports, for example, pachinko ball separation discharge ports 14 are formed at appropriate intervals. The pachinko ball separation discharge port 14 is formed in a chute shape, and a bellows tube 15 is coupled to the lower end thereof as shown in FIGS. 3 and 4A. Pachinko balls that have entered each pachinko ball separation / discharge port 14 are supplied to the pachinko machine 1 corresponding to each pachinko ball separation / discharge port 14 via the bellows tube 15.

  An overflow port 16 is formed on the left end side, which is the terminal end of the transport device 10, for passing the pachinko ball transported to the terminal end to the overflow unit 7. The overflow port 16 is also formed in a chute shape, and the bellows tube coupled to the lower end thereof is used as the overflow portion 7.

  The bottom wall 12 is provided with a plurality of conveying members 20a to 20h for conveying the pachinko balls supplied on the bottom wall 12 to the downstream side, that is, the overflow port 16 side. The conveying members 20a to 20d are provided in a row at a position closer to the one side wall 13 from the center of the bottom wall 12, and the conveying members 20e to 20h are arranged from the center of the bottom wall 12 to the other side wall 13 side. It is provided in a row at the close position. One separation outlet 14 is located between the conveying members 20a and 20b, and another separation outlet 14 is located between the conveying members 20c and 20d. Similarly, one separation / discharge port 14 is located between the conveying members 20e and 20f, and another separation / discharge port 14 is located between the conveying members 20g and 20h. Further, the conveying members 20a and 20h are arranged at positions corresponding to each other on both sides of the central portion of the bottom wall 12, and the conveying members 20b and 20g are arranged at positions corresponding to both sides of the central portion of the bottom wall 12, The conveying members 20 c and 20 f are arranged at positions corresponding to each other on both sides of the center portion of the bottom wall 12, and the conveying members 20 d and 20 e are arranged at positions corresponding to each other on both sides of the center portion of the bottom wall 12. Although only the conveying members 20a to 20h are shown in FIG. 2, in reality, more conveying members are provided from the upstream side to the downstream side of the bottom wall 12.

  As shown in FIG. 5, these conveying members 20 a to 20 h have a columnar body portion 21, for example, a columnar body portion 21. The main body 21 has an inclined surface 21a formed by cutting the upper surface obliquely. A link locking portion 22 is attached to the lower surface of the main body portion 21.

  As shown in FIG. 2, openings 23 penetrating in the vertical direction of the bottom wall 12 are formed at the installation positions of the conveying members 20 a to 20 h on the bottom wall 12. The diameters of these openings 23 are slightly smaller than ½ of the width of the bottom wall 12 and are slightly larger than the diameter of the main body 21 of the conveying members 20a to 20h. As shown in FIG. 3, a sleeve extending downward, for example, a flange portion 24, is formed on the periphery of the openings 23.

  The main body portions 21 of the conveying members 20a to 20h are arranged in these openings 23 so that the inclined surfaces 21a face the direction of conveying the pachinko balls, that is, the overflow port 16 side. A gap smaller than the diameter of the pachinko ball is formed between the main body portion 21 and the flange portion 24, and the main body portion 21 can move up and down in the flange portion 24. That is, as shown on the left side of FIG. 3, the projecting position where the inclined surface 21a of the main body 21 protrudes from the opening 23 can be taken, and as shown on the right side of FIG. It is also possible to take a non-projecting position that is lower than the upper end of the flange 24, specifically, the upper end of the flange 24. The diameter of the opening 23 is formed to be somewhat larger than the diameter of the flange 24, and an inclined surface 23 a that is inclined downward from the opening 3 toward the flange 24 is formed therebetween.

  In order to reciprocate the transport members 20a to 20h between the protruding position and the non-projecting position, each of the transport members 20a to 20h is provided with a driving unit, for example, a driving device 25. These driving mechanisms 25 are located below the bottom wall 12 and below the conveying members 20a to 20h. As shown in FIGS. 3 and 4A, the drive mechanism 25 is a known slider crank mechanism including, for example, a motor 25a, a rotating cam 26 connected to the motor 25a, and a link 27. The link 27 is engaged with the link locking portion 22 of the main body 21 of the conveying members 20a to 20h described above, and by rotating the motor 25a, the conveying members 20a to 20h have a protruding position and a non-projecting position. Reciprocate between. The drive device 25 is not limited to the slider crank mechanism, and any other known drive mechanism may be employed as long as it can reciprocate the transport members 20a to 20h.

  Now, it is assumed that many pachinko balls are supplied onto the bottom wall 12 through the chute 6. Some of the large number of pachinko balls are placed on the inclined surfaces 21a of the conveying members 20a to 20h at the non-projecting positions in the respective openings 23. In this state, when each conveying member 20a to 20h moves to the projecting position, the pachinko balls on the inclined surface 21a roll on the inclined surface 21a vigorously, and these rolled pachinko balls are on the bottom wall 12. Colliding with the pachinko balls that are stationary, the pachinko balls roll, and the entire pachinko balls in the transport device 10 are imparted with transport force in the transport direction, that is, toward the overflow port 16. During this time, since the bottom wall 12 is inclined toward the side walls 13, some of the pachinko balls to which the conveying force is applied roll to the side walls 13 side and are discharged from the separation outlet 14. , Supplied to each pachinko machine 2.

  In addition, when each conveyance member 20a thru | or 20h exists in a non-projection position, since the inclined surface 21a of the main-body part 21 of the conveyance member 20a thru | or 20h exists in a position lower than the surface of the bottom wall 12, it is inclined surface 21a and a collar part. 24, recessed portions are formed, and pachinko balls are accumulated in these recessed portions. That is, a large amount of pachinko balls are placed on the inclined surface 21a of the main body 21 of the conveying members 20a to 20h. Therefore, when each conveyance member 20a thru | or 20h moves to a protrusion position, conveyance force can be provided to more pachinko balls. Furthermore, since the inclined surface 23a is formed between the peripheral edge portion of the opening 23 and the upper end portion of the flange portion 24, the opening of the recessed portion is widened, and more pachinko balls are placed in the main body of the conveying members 20a to 20h. It can be placed on the inclined surface 21 a of the portion 21.

  In the above-described embodiment, one transport device 20a to 20h is driven by one drive device 25. However, as shown in FIG. 4B, the cam protrusion 28 of the rotary cam 26 is formed on the bottom wall 12. It is also possible to extend in the width direction and simultaneously drive two conveying members, for example, conveying members 20b and 20g. Further, if the installation direction of the driving device 25 is appropriately selected, a plurality of conveying members along the length direction of the bottom wall 12, for example, conveying members 20 b and 20 c can be driven by one driving mechanism 25. In any case, not all the conveying members are driven by one drive mechanism 25.

  In this way, one drive device 25 and one or a relatively small number of a plurality of transport members are unitized as a transport member unit, and the transport device 10 is provided with a plurality of units, thereby providing a certain transport member. Even if a trouble such as a failure occurs in the unit, the trouble does not spread to other transport member units.

  Further, since the main body portion 21 of each transport member 20a to 20h is cylindrical, when each transport member 20a to 20h is in the protruding position, the pachinko balls transported from the upstream side are each transport member 20a to 20h. Even if it hits the peripheral surface of the main body part, it moves around the peripheral surface and rolls in the downstream direction while changing the angle, so that the pachinko ball transport flow is not completely stopped. More preferably, if the upstream side of the peripheral surface of the main body portion 21 is cut at both sides of the diameter along the conveyance direction of the pachinko balls so as to form an acute angle with respect to this diameter, it becomes more difficult to prevent the conveyance flow.

  The overflow port 16 is not always necessary. That is, all the pachinko balls in the replenishing device 5 may be discharged to the outside only by replenishing each pachinko machine 2 via the separation discharge port 14. In this case, the transport members 20a and 20h are not necessary.

  In the above embodiment, the driving device 25 is provided for each of the one or two rotating members, and the entire pachinko ball conveying function is not stopped even if a failure occurs in the conveying members 20a to 20h or the driving device 25. However, in this embodiment, as shown in FIG. 2, the diameter of the main body 21 of the conveying members 20a to 20h is set to be slightly smaller than half the width of the bottom wall 12. If 25 fails, the pachinko ball conveyance on one side of the bottom wall 12 almost stops.

  In order to avoid this situation, in the transport apparatus of the second embodiment, as shown in FIG. 6, the diameter of the transport member 20 in plan view is sufficiently smaller than half the width of the bottom wall 12, A plurality of, for example, two, for example, two conveying members 20 are arranged in the width direction of the conveying path, for example, from the side wall 13 to the central portion of the bottom wall 12. Of course, the conveying member 20 is also arranged in the conveying direction of the bottom wall 12. The configuration of the conveying member 20 is the same as that of the conveying members 20a to 20h of the first embodiment. One conveying member 20 is one driving device 25, or a relatively small number of conveying members 20 are one driving. It is driven by the device 25.

  Accordingly, even if driving of any one of the conveying members 20 is stopped, a sufficient space for the pachinko balls to flow around the stopped conveying member 20 is secured, so that the pachinko ball conveying function of the entire conveying device 10 is ensured. Will not be stopped.

  In the transport apparatus of the third embodiment, the configuration of the transport member 30 is different from the transport members 20a to 20h of the first embodiment. The main body 31 of the conveying member 30 has a substantially fan-shaped shape, and the arcuate surface 32 is arranged on the upstream side of the conveying device 10. In the lower part, a link locking part 33 is provided, and this locking part 33 is coupled to the same driving device 25 as the driving device 25 of the first embodiment.

  An opening 34 into which the conveying member 30 is fitted is formed in the bottom wall 12, and a flange portion 35 extending to the opening 34 extends downward. The conveying member 30 is swung around a shaft 36 provided along the width direction of the bottom wall 12 on the downstream side of the opening 34. Accordingly, the non-projecting position where the upper surface 37 of the main body 31 of the conveying member 30 is located below the opening 34 and the projecting position where the upper surface 37 projects above the bottom wall 34 and faces the downstream side are repeatedly taken. .

  As shown in FIG. 8, a part of the upstream side of the main body 31, for example, both sides, is provided with a notch 38 facing the pachinko ball conveying direction. Since the notch surface of the notch 38 forms an acute angle with respect to the pachinko ball conveyance direction, the pachinko ball on the upstream side of the conveying member 30 moves along the notch 38 when the conveying member 30 is in the protruding position. In addition, there is an effect that the flow of the pachinko ball is not stopped.

  The transport apparatus according to the fourth embodiment has a configuration in which a plurality of transport apparatus units 40 having appropriate lengths are connected. This transport apparatus is similar to the main body 11 of the first embodiment, but a pair of separation discharge ports 14 are formed on both side walls of the transport path member 41 whose length is slightly longer than the lateral width of the pachinko machine 2. A plurality of conveying members 42 are provided on the bottom wall, and the conveying member 42 is driven by a driving device (not shown). The conveyance member 42 uses any of the conveyance members of the first to third embodiments. The driving device is also the same as that shown in the first to third embodiments.

  The transport path member 41, the transport member 42, and the driving device constitute a transport device unit 40, and the transport device 10 is configured by connecting a plurality of transport device units.

  Thereby, compared with the case where it is set as one long conveying apparatus, it becomes possible to adjust the length of the conveying apparatus 10 suitably, and conveyance and an assembly | attachment become easy. As the transport unit 40, only the transport path member 41 is provided, the transport member 42 and the separation outlet 14 are not provided, the transport path member 41 is provided with only the transport member 42, and the transport path member 41 is provided. It is also possible to prepare a plurality of types such as those provided with only a separation discharge port, and to configure the transport apparatus 10 by appropriately combining the plurality of types.

  Furthermore, in recent years, in order to produce the uniqueness of pachinko halls, there are many requests for constructing curved pachinko islands. However, as shown in FIG. 9, a plurality of transfer device units 40 are arranged via triangular spacers 43 in plan view. By connecting, the entire conveying device 10 can be curved or meandered, and the above-mentioned requirements can be easily answered.

  In the above embodiment, the main body 11 is arranged horizontally from the chute 6 side to the overflow part 7, but in order to increase the efficiency of conveying the pachinko balls, the chute 6 side is high and the overshoot 7 side is low, that is, It is also possible to arrange the main body portion 11 slightly inclined so that the upstream side is high and the downstream side is low. Even in this case, it is not necessary to incline as much as what is conveyed using the positional energy of the pachinko balls, such as a collection basket and a conveyance basket as shown in Patent Document 1, and if an inclination that can be regarded as substantially horizontal is provided. Well, the height of Pachinko Island 1 can be lowered.

  In the above embodiment, the transport device 10 is implemented as a replenishment device, but can also be used as a recovery device for pachinko islands 1 or a transport device for pachinko balls between pachinko islands. When used as a recovery device or an inter-island transport device, the separation outlet 14 can be removed.

  In the above embodiment, since the transport device of the present invention is used as the replenishment device for the Pachinko islands on both islands, the separation discharge ports are provided on both sides in the transport direction of the transport device 10, but the pachinko is provided only on one side. In the case of Katashima equipped with the machine 2, it is sufficient to provide a separation outlet only on one side. In that case, the bottom wall 12 should just incline below toward the side provided from the side in which the separation discharge port is not provided among the both longitudinal edges.

  In the above-described embodiment, the bottom wall 12 has an inverted V-shaped longitudinal cross-sectional shape, but is not limited thereto, and the slope is curved in an arc shape from the vicinity of the center in the width direction of the bottom wall 12 toward both sides. The pachinko ball to be conveyed is on the side of the rotating roller, such as a curved type with a curved cross section or a polygonal type with a vertical cross section whose inclination angle changes in the middle from the center in the width direction of the bottom wall 12 to both sides. Any shape can be used as long as it has a slope that can be guided to the surface.

  In the above embodiment, the present invention is implemented for the conveyance of pachinko balls. However, the present invention is not limited to this, and the present invention can also be used for conveyance of other spheres, for example, ball bearing balls.
