Description

  The present invention relates to a rectifying rod for a ball game machine such as a pachinko machine or a smart ball.

  For example, in a pachinko machine that is a typical ball game machine, a predetermined number of game balls (in this case, pachinko balls) are discharged and given to the player as a reward for a winning that occurred during the game. Therefore, as shown in FIG. 5, in the substrate 1 on the back surface of the pachinko machine, a storage tank 2 that is located at the top and stores a considerable number of balls is aligned with a plurality of balls received from the storage tank 2. The rectifying rod 3 that is sent out in this manner and the sending rod 4 that sends the sphere sent out from the rectifying rod 3 to a downstream ball discharge device (not shown) are arranged. Here, the ball outlet 5 of the storage tank 2 can flow the ball to the upstream end of the flow straightener 3 without difficulty. For the discharging mechanism having such a configuration, it is required to always send out the sphere smoothly and smoothly so as not to cause clogging of the sphere or defective sphere flow.

  Normally, pachinko balls circulate through each store (pachinko machine) in the store and are collected in a cleaning device installed at a predetermined place, where they are washed with resin pellets (trade name Polylon) and then again. Although it is supplied to each table, pachinko balls are often transported while foreign substances such as cleaning resin pellets, dust, and dust adhere to the pachinko balls or enter the flow of the pachinko balls. . In this case, when the foreign matter flows down together with the ball to the flow straightening rod 3 and reaches the ball feeding mechanism 6 on the downstream side of the flow straightening rod 3 or a counting device (not shown) below the feed rod 4, the foreign matter is Ball clogging easily occurs as an obstacle. Therefore, it is necessary to remove the foreign matter while the foreign matter is in the flow rectifier 3.

As shown in FIG. 6, the conventional rectifying rod 3 is provided with a partition wall 7 having a height of more than half of the diameter of the pachinko sphere P at the center of the cross section, forming a spherical passage on both sides thereof, and rectifying It is known that the ball is smoothly rolled by providing a rectifying groove 8 having an appropriate width on the bottom surface of the bowl 3, but in this case, the rectifying groove 8 is used as a foreign matter discharge port, From here, the foreign matter in the flow straightener 3 was removed (Patent Document 1).

  However, in the rectifying basin as described above, foreign matter such as dust existing on the bottom surface is discharged to some extent from the rectifying groove, but in the rectifying basin structure described above, it is formed by the bottom surface and the side wall or partition wall. Since a gap is generated at the corner of each spherical passage, foreign matter such as dust tends to remain here. The accumulation of foreign matter prevents smooth movement of the sphere, and if the foreign matter moves together with the ball to the downstream side of the rectifying rod, it adversely affects the downstream ball discharge mechanism and hinders the payout of the winning ball. Will be.

  Accordingly, an object of the present invention is to provide a rectifier that can effectively remove foreign matters such as those described above mixed in the flow of game balls in a ball game machine.

The present invention relates to a rectifier rod provided with a ball passage for supplying game balls used in a ball game machine in an aligned manner from the upstream side to the downstream side, and is provided on the bottom surface of the ball passage over the entire length of the ball passage. consist linear opening of a width smaller than the diameter of the sphere, the game balls provided with a rectifying groove for sending aligned in a row, the boundary portion between the bottom surface and the inner wall surface of the ball passage, the gaming ball passes Provided with a through hole for discharging foreign matter that is not discharged from the rectifying groove, and provided with a reinforcing part at the bottom of the rectifying groove, the reinforcing part is located on the side of the through hole, Reinforcing plates are arranged on the outer bottom surface of the spherical passage with a predetermined interval in the longitudinal direction of the spherical passage, and the reinforcing plates are positioned on both sides of the reinforcing portion in the longitudinal direction of the spherical passage. characterized in that it.

  In the flow straightener of the present invention, a convex portion (rib) formed so as not to disturb the flow of the game ball may be provided at the downstream edge of the through hole at the boundary portion between the bottom surface and the inner wall surface of the ball passage. preferable. In this case, the convex portion can be formed as an inclined wall extending between the bottom surface and the inner wall surface of the spherical passage.

  In the flow rectifier of the present invention, even if there is foreign matter such as dust on the ball passage, it is discharged from a through hole provided at the boundary portion between the bottom surface and the inner wall surface of the ball passage. Of course, the sphere does not exit the through hole. More specifically, the foreign matter in contact with the sphere is discharged when it reaches the through-hole while moving with the sphere. Further, the boundary portion between the bottom surface and the inner wall surface of the spherical passage is a region including the corner portion of the spherical passage formed by the bottom surface and the side wall or the partition wall. It is discharged from a through hole provided in the boundary portion. In any case, foreign matter existing on the ball passage is effectively discharged from the through hole, so that the foreign matter stays in the corner of the ball passage or causes clogging on the downstream side as in the prior art. Nothing will happen.

  Further, by providing a plurality of the above-mentioned through holes at predetermined intervals in the length direction of the ball passage and on both sides of the bottom surface of the ball passage, the opportunity or frequency of discharging foreign matter increases, and the ball passage is on the ball passage. Foreign matter can be discharged more quickly.

  In addition, when a protrusion (rib) that does not obstruct the flow of the game ball is provided at the downstream edge of the through hole, foreign matter is blocked by the protrusion and falls into the through hole. The foreign matter adhering to the surface of the material can be easily removed, and the foreign matter is more reliably discharged. Furthermore, by forming the convex portion as an inclined wall extending between the bottom surface and the inner wall surface of the ball passage, a structure can be obtained that has a simple shape and does not prevent the movement of the game ball and prevents the foreign object from moving downstream.

[Example]
FIG. 1 shows a part of a substrate on the back side of a pachinko machine using the rectifier of the embodiment. A storage tank 12 for storing a considerable number of pachinko balls supplied from a ball supply device (not shown) is disposed on the upper surface of the substrate 11 on the back surface of the pachinko machine. A ball outlet 13 through which a plurality of balls can flow out is provided at the left end of the storage tank 12 at the left end in the figure.

  Below the storage tank 12, the flow straightening rod 14 of the embodiment is disposed so as to be inclined gently to the lower right. A sphere receiving portion 15 that receives supply of a sphere from the sphere outlet 13 of the storage tank 12 is provided at the left end of the rectifying basin 14 in the drawing, and a delivery path 16 is provided at the right end of the rectifying basin 14 as one sphere. Formed, its lowermost end is connected to the delivery rod 17.

  The flow straightening rod 14 has a ball leveling plate 18 made of an elastic thin plate at a substantially central position, and a claw-like protrusion that rotates to send the balls one by one to the delivery rod 17 at the downstream end. The sprocket 21 is provided. The sphere leveling plate 18 levels the spheres in the flow straightening rod 14 from the irregular state to the regular state, and the sprocket 21 regularly sends the spheres one by one to the feeding rod 17 positioned below the spheres.

  As shown in FIG. 2, the rectifying rod 14 is horizontally long and is formed in a bowl shape whose upper surface is opened by both side walls 22. The inside of the rectifying rod 14 is divided into two rows by a partition wall 23 provided at the center of the bottom surface along the ball sending direction, and two ball passages 19 and 20 are formed. Each of the ball passages 19 and 20 is provided with rectifying grooves 24 and 25 that are linearly cut from the ball receiving portion 15 to the delivery passage 16, whereby the spheres are laterally moved in the ball passages 19 and 20. It is easy to send out one line at a time. Since the rectifying grooves 24 and 25 extend over substantially the entire length of the rectifying rod 14, the plurality of reinforcing plates 26 (FIG. 1) are arranged on the outer bottom surface of the rectifying rod 14 at a predetermined interval, thereby rectifying The bottom of the ridge 14 is reinforced. The rectifier rod 14 has a gentle gradient (horizontal inclination) from the ball receiving portion 15 to the delivery path 16 described above, and rolls the ball from the ball receiving portion 15 side to the delivery path 16 side by its own weight. It is like that.

  The sphere leveling plate 18 has a substantially H-shape when viewed from above, and has a flat portion facing substantially parallel to the spherical passages 19 and 20 at the center. On the upstream side of the flat portion, an upper inclined portion formed so as to be positioned at the upper side of each spherical passage has an inclination angle larger than the gradient of the spherical passages 19 and 20. On the downstream side of the flat portion, a downwardly inclined portion that is also bifurcated and inclined downward extends. The sphere leveling plate 18 is formed of an elastic thin plate. This is to prevent clogging of the sphere due to elasticity when the upper inclined portion and the lower inclined portion come into contact with the sphere moving in the ball passages 19 and 20. belongs to.

  The sphere leveling plate 18 is supported on overhang portions 27 and 28 that project outward from the upper edges of the side walls 22 of the rectifying rod 14. A mounting portion (not shown) having a screw hole formed therein is integrally provided below the overhang portions 27 and 28, so that a screw is inserted into the screw hole of the mounting portion from above the ball leveling plate 18. By inserting 29 and 30 and stopping, the ball leveling plate 18 is fixed so as to bridge above the two ball passages 19 and 20.

  As described above, the width of the rectifying grooves 24 and 25 provided in the ball passages 19 and 20 of the rectifying rod 14 is smaller than the diameter of the sphere, and these rectifying grooves have a function as a rail for guiding the sphere. As described above, it also serves as an opening for discharging foreign matter such as resin pellets and dust mixed in the flow of the pachinko sphere. However, foreign matters that are not discharged from the rectifying grooves 24 and 25 enter the corner portions 32 (FIG. 3) of the spherical passages 19 and 20 formed by the side walls 22 and the bottom surface 31 or the partition walls 23 and the bottom surface 31 of the rectifying rod 14 and accumulate. It's easy to do.

  On the other hand, in the present embodiment, the boundary portion between the bottom surface 31 and the inner wall surface (in this case, each wall surface of the side wall 22 and the partition wall 23) including the corner portions 32 of the ball passages 19 and 20 (both sides of the bottom surface 31). A plurality of through holes 33 having predetermined widths and lengths are provided. In order to reinforce the bottom surface portion of the rectifying rod 14, in addition to the above-described reinforcing plate 26, reinforcing portions 34 arranged in three rows in the length direction between the through holes 33 on both sides of each of the ball passages 19 and 20 are provided. The rectifying grooves 24 and 25 are integrally provided.

  Furthermore, in this embodiment, a rib 35 is provided at one end on the downstream side of each through hole 33. As shown in FIG. 4, these ribs 35 are formed as inclined walls extending from the bottom surface to the inner wall surface of the respective ball passages 19 and 20, and pachinko balls P that roll in the respective ball passages 19 and 20. Does not impede the flow of pachinko spheres.

  In the rectifying rod 14 configured as described above, foreign matters other than the spheres are dropped and discharged from the through-hole 33 provided in the boundary portion between the bottom surface and the inner wall surface of the spherical passages 19 and 20. Will not accumulate or remain in the corner 32 of each spherical passage. Further, the foreign matter adhering to the pachinko sphere or mixed in the flow comes into contact with or hits the rib 35 on the downstream edge of the through hole 33 and is prevented from moving to the downstream side. Since it falls, foreign matter is more reliably discharged. Furthermore, since the rib 35 is formed as an inclined wall, the movement of the pachinko sphere is not hindered and only the movement of the foreign matter can be prevented. The rib 35 may have any shape as long as it does not prevent the movement of the sphere.
