  The present invention relates to a so-called pachinko machine installation island that is installed in a pachinko hall and has a plurality of pachinko game machines arranged in a row, in a pachinko game machine installation island that is disposed between a lower lifting device and an upper supply tank. The present invention relates to a feeding pipe of a replenishing device.

  Conventionally, a so-called pachinko game machine installation island in which many pachinko machines are arranged in a back-to-back state on both sides has been installed in the pachinko hall. A supply device for circulating and supplying pachinko balls to each pachinko gaming machine is disposed in the pachinko gaming machine installation island. This replenishing device includes a ball polishing device that polishes pachinko balls that circulate, a foreign material removal device that removes foreign matters such as polishing dust, a lifting device that lifts the polished pachinko balls to a replenishment tank via a lifting pipe, and It is generally composed of

A sprocket having a plurality of recesses that are rotated by a drive motor and into which one pachinko ball can be fitted one by one is arranged in the lifting device. In addition, the lifting pipe is arranged upright between the lifting device and the replenishing tank, and usually has a plurality of square cylindrical pipe bodies arranged in parallel, and the back side of the pachinko machine Narrow gaps can be passed between them. Then, the pachinko balls squeezed by the sprocket are lifted so as to be pushed up from the bottom in a state where each pipe body of the lifting pipe is aligned in line with the rotation of the drive motor, and from the upper end opening of each pipe body to the inside of the supply tank Is discharged. Pachinko balls stored in the replenishment tank are replenished to each pachinko gaming machine from both sides of the replenishment tank via replenishing ball cages arranged along the longitudinal direction of the pachinko gaming machine installation island. In addition, pachinko balls discharged from each pachinko gaming machine fall to a recovery ball cage arranged along the longitudinal direction at the lower part of the island where the pachinko gaming machine is installed, and are transported through a ball polishing device and a foreign matter removing device. Collected in the apparatus (for example, see Patent Document 1).
Japanese Patent Laid-Open No. 2002-273018 (page 2-3, FIGS. 1 to 3)

  The lifting pipe in Patent Document 1 is arranged such that the upper end opening of each pipe body faces directly upward in the replenishing tank, and the upper end opening is formed substantially horizontally. For this reason, pachinko balls that are pushed up in each pipe body at a constant speed are released almost directly above the upper end opening, but some of them fall into the vicinity of the original upper end opening, or adjacent pachinko balls There are things that collide with each other.

  In this way, once the pachinko sphere released from the upper end opening returns to the vicinity of the upper end opening again or collides with the adjacent pachinko sphere, it interferes with the subsequent pachinko spheres and this impact is caused in the transport pipe. It propagates to the pachinko sphere that is pushed up. Thereby, a compulsory impact equivalent to the number of pachinko balls arranged in the vertical direction in the pipe body is applied to the drive motor by pulling the sprocket. For this reason, the drive motor is burdened with an unnecessary load, which is one cause of quickly damaging the drive motor and shortening its life, and a solution to improve this point has been strongly desired.

  Therefore, the present invention has been made to solve the above-mentioned problems, and the life of the drive motor is reduced by preventing unnecessary shocks and extra loads from being applied to the drive motor in the lifting device by the released pachinko balls. It is an object of the present invention to provide a lifting pipe for a replenishing device on an island where a pachinko machine is installed so that the extension cost can be reduced.

  In order to achieve such an object, the supply pipe of the replenishing device on the pachinko game machine installation island of the present invention has its upper end facing upward in the replenishment tank between the lower lifting device and the upper replenishment tank. A pachinko ball that is disposed and is discharged from the upper end of the pachinko ball to be discharged into the supply tank so as to be discharged upward from the upper end of the pachinko game machine installation island. A notch part that is provided with an inclined part inclined inward along the longitudinal direction on one side of the inner peripheral surface in the upper end part, and reaches the upper end on the other side of the inner peripheral surface facing the inclined part and through which a pachinko ball can pass The pachinko ball to be pushed up is discharged along the inclined portion.

  In this case, a plurality of pipe bodies are arranged in parallel on the same plane, and an inclined portion that is inclined inward along the longitudinal direction is provided on the same side of the inner peripheral surface of the upper end portion of each pipe body. A notch portion is provided on each other side of the inner peripheral surface facing the portion so as to reach the upper end and allow a pachinko ball to pass through, and each of the pachinko balls to be pushed up is discharged to the same side along the inclined portion. It is preferable.

  In addition, it is preferable that the upper end portion of each pipe body is cut obliquely toward the inclined portion side so that the cut end becomes the notched portion.

  Further, the cutouts at the upper end of the pipe body located at both ends may be oriented 90 degrees in the horizontal plane with respect to the directions of the cutouts of the other pipe bodies with their orientations facing away from each other. preferable.

  Furthermore, it is preferable that each upper end side is separated from each pipe body to form an upper end split part, and the upper end split part can be detachably connected to each pipe main body by appropriate connecting means.

  The feeding pipe of the replenishing device in the pachinko gaming machine installation island according to claim 1 and claim 2 is provided with an inclined portion inclined inward along the longitudinal direction on one side of the inner peripheral surface of the upper end portion thereof. A notch portion is provided on the other side of the inner peripheral surface facing the portion so as to reach the upper end and allow a pachinko ball to pass through. As a result, the pachinko balls to be pushed up are released along the inclined portion, and all fall off the lifting pipe, so that the pachinko balls released from the upper end portion do not return to the upper end portion again. That is, all the pachinko balls are smoothly pushed up and released from the upper end portion, so that unnecessary impact and extra load are not applied to the drive motor. Therefore, there is a beneficial effect that the life of the drive motor can be extended and the cost can be reduced.

  Since the lifting pipe of the replenishing device in the pachinko machine installation island according to claim 3 is cut at an upper end portion of each pipe body obliquely toward the inclined portion side, the cut end becomes the notched portion. In addition to the above effects, the contact of the pachinko sphere released from the upper end portion of the pipe body with the surroundings is reduced and freed. As a result, the pachinko flows more smoothly, and unnecessary impacts and extra loads are not applied to the pachinko balls pushed up from below, and the effect of reducing the load on the drive motor is enhanced.

  The feeding pipe of the replenishing device in the pachinko machine installation island according to claim 4 is such that the direction of the notch portion of the upper end portion of the pipe body located at both ends faces opposite to each other and the direction of the notch portion of the other pipe body. On the other hand, since the positions are different by 90 degrees in the horizontal plane, the directions of the pachinko spheres emitted from the pipe bodies at both ends are completely different from the directions of the pachinko spheres emitted from the other pipe bodies. Therefore, the chances of pachinko balls emitted from the upper ends to interfere with each other are reduced as much as possible, and the effect of reducing unnecessary impacts and extra loads on the drive motor is further enhanced.

  Further, the lifting pipe of the replenishing device in the pachinko machine installation island according to claim 5 forms each upper end part by separating each upper end part from each pipe body and appropriately connects the upper end part by a connecting means. Since each pipe body can be detachably connected, for example, when the upper end portion is damaged, it is not necessary to replace only a part thereof to replace the entire pipe body, which is extremely economical. There is.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a lifting pipe (hereinafter simply referred to as “lifting pipe”) of a replenishing device in a pachinko gaming machine installation island according to the present invention will be described below with reference to the drawings. FIG. 1 is a front view of a pachinko gaming machine installation island to which the present invention is applied, and FIG. 2 is a front view of a supply device in the pachinko gaming machine installation island. The pachinko machine installation island A is installed in a plurality of rows in the pachinko hall, and is placed on the upper surface of the base plate 1 stretched along the longitudinal direction of the lower part so that the plurality of pachinko gaming machines P are back-to-back on both sides. Lined up.

  The pachinko gaming machine installation island A is provided with a replenishing device B for circulating and replenishing pachinko balls to each pachinko gaming machine P at the center of the inside. This replenishing device B includes a ball polishing device 2 for polishing circulating pachinko balls, a foreign material removing device 3 for removing foreign matters such as polishing dust, and a polished pachinko ball to an upper replenishing tank 5 via a lifting pipe 4. It is generally composed of a lifting device 6 for lifting. Supply ball cages 7 and 7 which are gently inclined downward from the supply tank 5 to both ends of the pachinko gaming machine installation island A are arranged so that the pachinko balls can be supplied to each pachinko game machine P. On the other hand, below the pachinko gaming machine P, a collection bulb 8 that is inclined downward toward the ball polishing device 2 is disposed.

  As shown in FIG. 3, the lifting device 6 has a rectangular parallelepiped shape, in which a sprocket housing chamber 9 is formed, and a sprocket 10 is pivotally mounted in the sprocket housing chamber 9. On one side of the sprocket housing chamber 9, there is provided a ball insertion passage 11 that communicates with the sprocket housing chamber 9 and receives a pachinko ball emitted from the foreign matter removing device 3. Further, on the other side of the sprocket housing chamber 9, a ball outlet passage 12 is provided which communicates with the sprocket housing chamber 9 and discharges pachinko balls. A plurality of sprockets 10 are separated from the horizontal support shaft 13 by a predetermined distance, and five sprockets 10 in this embodiment are attached to the shaft. A number of recesses 14 into which pachinko balls are inserted are provided at the outer peripheral edge of each sprocket 10 and are rotated at a predetermined rotational speed in the direction of the arrow in FIG. The pachinko ball is pushed up while being sandwiched between the arcuate inner side surface 9a.

  The lifting pipe 4 is arranged in a state where five pipe main bodies 16 are arranged in the same plane and in parallel according to the number of sprockets 10, and are standing almost straight between the lifting device 6 and the replenishing tank 5. Is done. The lifting pipe 4 is installed in a narrow space in the pachinko machine installation island A, and may be slightly inclined or slightly bent or bent at the center due to the assembly, but it is almost straight. Both of these are included in the standing uplifting pipe 4. As shown in FIG. 3, the lower end portion 16a of each pipe body 16 is connected to the ball outlet passage 12 of the lifting device 6, and the upper end portion 16b of each pipe body 16 is replenished as shown in FIGS. Arranged in the tank 5. The reason for arranging the five pipe bodies 16 in this way is to obtain a predetermined lifting capacity. However, the number can be selected as appropriate, but if it is too large, the installation space of the pachinko gaming machine P will be adversely affected.

  Each pipe body 16 is made of, for example, ultra high molecular weight polyethylene, which is a synthetic resin, and has a square tube shape with a square cross section. This is because it can be easily formed by extrusion. In addition, the molding cost can be reduced. One side of the inner peripheral surface of each pipe body 16 is set to 12 mm. In addition, each pipe body 16 may be made of a synthetic resin such as polyacetal or ABS, or a metal such as iron, aluminum or stainless steel.

  As shown in FIGS. 4A and 4B, the upper end portion 16b of each pipe body 16 is in contact with the inner wall surface 5a on one side of the replenishing tank 5 and is disposed substantially vertically. Then, one side wall 17a of the inner peripheral surface at the upper end portion 16b of each pipe body 16 (the inner surface 5a side of the replenishing tank 5) is cut from the upper end along the longitudinal direction on both sides thereof, for example, 15 degrees with respect to the vertical line. The inclined portion 18 is provided on the one side wall 17a by inclining inward at the front and rear inclination angles. The inclined portion 18 may be provided with a protruding portion having an inclined surface on the inner surface thereof without tilting the one side wall 18. In addition, a notch portion 20 that reaches the upper end 19 and allows a pachinko ball to pass through is provided on the other side wall 17b of the inner peripheral surface facing this. The inclined portion 18 and the notch portion 20 in each pipe body 16 are all provided at the same position.

  Therefore, the pachinko balls collected in the lifting device 6 are pushed upward at a predetermined speed in the pipe main bodies 16 of the lifting pipe 4 through the ball exit passage 12 by the rotation of the sprocket 10. Then, at each upper end, as shown in FIG. 4B, the uppermost pachinko ball is pushed out along the inclined portion 18, and all are released in the same oblique direction. Thereby, all the released pachinko balls will fall away from each pipe body 16, and the released pachinko balls will not fall again and return to the vicinity of the upper end 19 or collide with the adjacent pachinko balls, All are released smoothly. Therefore, the pachinko ball that is pushed up inside the pipe main body 16 and lifted does not apply unnecessary impact or extra load to the drive motor 15.

  The pachinko balls stored in the supply tank 5 flow out to the supply ball cages 7 and 7 and are supplied to the respective pachinko gaming machines P. On the other hand, the pachinko balls that have been discharged and dropped from each pachinko machine P are received by the collecting ball cage 8 and flow down to flow into the ball polishing device 2. Here, the foreign matter is removed and the foreign matter is removed by the next foreign matter removing device 3 and flows into the lifting device 6. In this way, pachinko balls circulate in the pachinko machine installation island A.

  5 (a) and 5 (b) show an example of use of the lifting pipe 41 according to the other embodiment 1, and the upper end portion 16b of each pipe body 16 according to the present embodiment is directed to the inclined portion 18 side. By making an oblique cut, the cut end becomes the cutout portion 20. Thereby, there is no wall in the upper periphery from the notched portion 20 formed obliquely, and accordingly, the contact with the periphery of the pachinko sphere discharged from the upper end portion of each pipe body 16 is reduced and free from the bottom. Unnecessary impact or extra load is not applied to the pushed-up pachinko ball, and the effect of reducing the load on the drive motor is enhanced.

  6 and 7 relate to the second and third embodiments. As shown in FIG. 6, the lifting pipe 42 according to the other embodiment 2 includes both pipes positioned at both ends of the five pipe bodies 16 arranged in parallel in the lifting pipe 4 according to the present embodiment. The orientations of the notches 20 at the upper end portions 16b of the main bodies 161 and 161 are opposite to each other and the positions of the notches 20 of the other pipe bodies 16 are different by 90 degrees in the horizontal plane. As shown in FIG. 7, the lifting pipe 43 according to another embodiment 3 is positioned at both ends of the five pipe bodies 16 arranged in parallel in the lifting pipe 41 according to another embodiment 1. The orientations of the cutout portions 20 at the upper end portions 16b of the pipe main bodies 161 and 161 are opposite to each other and the positions of the cutout portions 20 of the other pipe main bodies 16 are different by 90 degrees in the horizontal plane.

  Thereby, the direction of the pachinko sphere emitted from the pipe main bodies 161 and 161 at both ends and the direction of the pachinko sphere released from the other pipe main body 16 are almost different by 90 degrees. Therefore, the chances of the pachinko balls emitted from the upper ends colliding with each other are reduced, and the effect of reducing the load applied to the drive motor 15 is further enhanced.

  FIGS. 8A and 8B also relate to other embodiments 4 and 5. FIG. As shown in FIG. 8 (a), the lifting pipe 44 according to another embodiment 4 has a pipe main body 16 according to this embodiment as shown in FIG. Molding. The lower end of the upper end split portion 21 is provided with a fitting recess 22 as connection means that is slightly larger than the inner periphery thereof. Further, a fitting convex portion 23 is provided at the upper end of the pipe body 16 as connecting means that fits into the fitting concave portion 22 slightly smaller than the outer periphery. The upper end split portion 21 can be detachably connected to the pipe body 16 by fitting the fitting convex portion 23 into the fitting concave portion 22. As shown in FIG. 8 (b), the lifting pipe 45 according to another embodiment 5 is different from the pipe body 16 in the pipe body 16 according to the other embodiment 1 in the same manner as described above. Separated and molded. The fitting concave portion 22 and the fitting convex portion 23 have the same structure as described above.

  As described above, in the other embodiments 4 and 5, the upper end split portion 21 is separated and molded and can be detachably connected to the pipe body 16, so that, for example, the upper end split portion 21 is inclined. When the part 18 is damaged, it is only necessary to replace the damaged upper end split part 21 with a new one, and it is not necessary to replace the entire pipe body 16, which is extremely economical. In this case, for example, the pipe body 16 may be made of a metal such as iron, aluminum, and stainless steel, and the upper end split portion 21 may be a synthetic resin material such as ultrahigh molecular polyethylene, polyacetal, and ABS.

  Although not shown in the drawings, a configuration that only cuts the upper end portion of the pipe body obliquely with respect to the longitudinal direction thereof, for example, the upper end portion of the rectangular tube-shaped pipe body is inclined obliquely from one side wall side to the other side wall side. Even if it is cut and the cut end is only oblique to the longitudinal direction of the pipe body, the effects of the present invention can be achieved.

  In the present invention, the pipe body has been described as having a rectangular tube shape in any of the embodiments, but it goes without saying that the present invention can be applied to a cylindrical body.
