Description

  The present invention relates to an apparatus for replenishing a ball tank for prize balls provided in a pachinko machine from a ball supply basket on an island.

  A device for replenishing a pachinko ball by dropping a supply cylinder from a ball supply basket on an island base into a ball tank for a prize ball provided on the upper back side of the front frame of the pachinko machine. As the ball is opened and closed, the ball tank is in a suspended or forward standing state in the ball tank, and the ball stop piece is moved into and out of the supply tube with the rotation to open and close the ball outlet of the supply tube. A pachinko ball replenishment device in which the outflow of a ball is controlled is known from Patent Document 1 below.

  By the way, the conventional pachinko ball replenishing device as shown in Patent Document 1 and the like is such that the replenishing cylinder rotates by opening the front frame, so that it remains in the replenishing cylinder when the front frame is suddenly opened. There was a risk that pachinko balls would spill out of the ball tank. For this reason, it is necessary to receive the ball that has flowed out of the supply cylinder with the palm of the other hand at the same time that the front frame is opened. Otherwise, there is a risk of scattering the spilled ball on the floor of the game hall.

  On the other hand, the pachinko ball replenishment device disclosed in Patent Document 2 described below closes the supply cylinder as soon as the front frame is about to be opened, and opens the supply cylinder only after the front frame is completely closed. Therefore, it was intended to improve the spillage of pachinko balls as described above.

  By the way, the shape of the ball tank provided in the pachinko machine differs depending on the manufacturer, and the position and height of the rear side wall of the ball tank when the front frame is closed, or the depth of the ball tank, etc. vary. In order to install the pachinko machine on the island, it is necessary to adjust the position and height of the pachinko ball supply device, and conventionally, a structure capable of adjusting them has been adopted. However, even with this adjustment, the conventional structure cannot adjust the supply cylinder in the front-rear direction and the relationship between the rotation angle of the supply cylinder and the opening and closing of the supply cylinder. It was difficult to set the timing for releasing the pachinko sphere into the ball tank as the frame was opened and the timing for stopping the release of the pachinko sphere as the front frame was closed to suit the situation. For this reason, there was a possibility that pachinko balls would still fall out, poor replenishment, and the like. The present invention is intended to solve such problems.

For this purpose, the present invention provides a ball tank on the upper back side of the front frame of a pachinko machine that is supported to be openable and closable forward, and the supply cylinder hangs down in the ball tank with the front frame closed.

Reference numeral 8d denotes a non-slip portion that is engraved on the surface of the vertical plate portion 8g of the mounting plate 8 so that the unevenness is formed in a rack tooth shape that is continuous in the vertical direction at the same constant pitch as the anti-slip portion 7f. Further, 8i is a scale that is engraved on the surface of one side edge of the vertical plate portion 8g of the mounting plate 8 so as to be continuous in the vertical direction. The scale has one scale of the anti-slip portion 8d and the anti-slip portion 7f. It should be the same as the pitch of the unevenness. A flange-shaped guide protrusion 8e is formed on one side edge of the horizontal plate portion 8h of the mounting plate 8, and a linear guide protrusion 8f is formed on the other side edge of the horizontal plate portion 8h. In addition, a rack tooth-shaped non-slip portion 8k is provided on the lower surface of the horizontal plate portion 8h. Reference numeral 14 denotes a female screw member inserted into the horizontal plate portion 8h of the mounting plate 8 so that the lower surface is opened.

  Reference numerals 10 and 11 denote bolts and wing nuts for fixing the slide plate 7 and the mounting plate 8 to the mounting rail 3. The head 10 a of the bolt 10 is loosely fitted in the dovetail groove 3 a of the mounting rail 3. Is passed through the through hole 7d of the slide plate 7 and the long hole 8c of the mounting plate 8, and the wing nut 11 is screwed and tightened to the tip of the bolt 10, whereby the slide plate 7 and the mounting plate 8 are fixed to the mounting rail 3.

Fixed. Then, by intentionally loosening the wing nut 11, the slide plate 7 and the mounting plate 8 can slide along the mounting rail 3, and at the same time, the mounting plate 8 is in the range of the long hole 8 c with respect to the slide plate 7. It can be moved at a constant pitch in the vertical direction.

  Reference numeral 12 denotes a substantially horizontal plate-like substrate on which a supply cylinder and the like to be described later are provided. The substrate 12 is brought into contact with the mounting plate 8 by sliding both end edges 12g, 12h of the substrate to the guide protrusions 8e, 8f. On the other hand, it is provided to be movable in the front-rear direction. As shown in FIG. 8, a long hole 12 a that is long in the front-rear direction is formed on one side edge of the substrate 12. Further, 12b is formed with a groove 12c that is long in the front-rear direction on the upper surface of the substrate 12, and the recesses and protrusions are engraved so as to form rack teeth that are continuous in the vertical direction at the same constant pitch as the anti-slip portion 8k. It is a non-slip part. Further, 12f is a scale that is engraved on the upper surface of the substrate so as to be continuous in the front-rear direction, and the scale is preferably the same as the pitch of the unevenness of the anti-skid part 8k and the anti-skid part 12b.

  Reference numeral 13 denotes a butterfly bolt for fixing the substrate 12 to the mounting plate 8. The butterfly bolt 13 is inserted into the elongated hole 12 a and the tip of the butterfly bolt 13 is screwed to the female screw member 14. As a result, the substrate 12 is fixed in close contact with the lower surface of the horizontal plate portion 8 h of the mounting plate 8. At this time, even if the tightening of the butterfly bolt 13 is somewhat loosened due to the engagement of the anti-skid part 8k and the anti-skid part 12b, there is no possibility that the substrate 12 is shifted back and forth. Then, by intentionally loosening the butterfly bolt 13, the substrate 12 can be moved with a constant pitch in the front-rear direction with respect to the mounting plate 8 within the range of the long hole 12a. For this reason, it becomes possible to set the substrate 12 to be always at the optimum position in relation to the ball tank of each pachinko machine.

  A pipe line 15 bent in an L shape in a horizontal plane is integrally formed on the lower surface of the substrate 12, and a rotation allowance joint 16 is fixed to the rearward projecting end of the pipe line 15 by a screw 16 a. An elbow 17 is rotatably connected to each other. Then, by connecting the hose 2 to the elbow 17, the pachinko balls flow down from the ball supply rod 1 through the hose 2 in a state of being aligned in a line, and enter the pipe line 15. The pachinko sphere is guided in the horizontal direction. Reference numeral 18 denotes a supply cylinder. An inlet 18b formed on one side of the base 18a of the supply cylinder is rotatably inserted into the outlet opening of the conduit 15, and a rotating shaft 18c is integrated with the other side of the base 18a. The rotary shaft 18c is inserted into a bearing 19 formed in a hanging shape on the lower surface of the substrate 12, so that the rotary shaft 18c is rotatably supported. Therefore, the supply cylinder 18 is always in communication with the pipe line 15 and is supported so as to be rotatable in a vertical plane. Reference numeral 20 denotes a coiled first spring in which one end 20a is fixed to the substrate 12 and the other end 20b is fixed to the rotating shaft 18c in order to urge the supply cylinder 18 to rotate forward. The supply cylinder 18 is rotated forward by the bias of the first spring 20, and the supply cylinder 18 comes into an upright standing state when the supply cylinder 18 comes into contact with the lower edge of the substrate 12.

  21 is a rod-shaped operating rod formed in a substantially square shape, 22 is a ball stop piece formed in a width plate shape, and the operation rod and the ball stop piece are integrally formed in a bifurcated shape having a base 23 in common. Is formed. Then, support shafts 24 are provided on both sides of the base portion 23, and the support shafts are located in the vicinity of the base portion 18a of the supply cylinder on the rear side of the supply cylinder 18 (lower side when the supply cylinder 18 is in the forward standing state). I support it. For this reason, the operating rod 21 extends rearward at a predetermined angle from the vicinity of the base 18a of the supply cylinder (below when the supply cylinder 18 is in the forward standing state), and can rotate in the same direction as the supply cylinder 18. Provided. Further, the ball stop piece 22 opens and closes the front end opening 18d of the supply cylinder 18 and extends along the rear surface of the supply cylinder 18 (the lower surface when the supply cylinder 18 is in the forward standing state) and is formed at the tip thereof. The protrusion 22a can be moved into and out of the supply cylinder from a notch 18e formed at the opening edge of the tip of the supply cylinder 18. Reference numeral 18f denotes a bearing body fixed by screws 25a and 25b so as to cover the base portion 18a of the supply cylinder 18. By inserting both end portions of the support shaft 24 into the bearing body 18f, the support shaft 24 is Actually, it is supported by the bearing body 18f.

  26 is a second spring provided on the outer periphery of the support shaft 24. One end of the second spring is fixed to a part of the bearing body 18f and the other end is fixed to the vicinity of the rear surface base of the operating rod 21; The actuating rod 21 is pushed forward by the elasticity of the second spring 26 and the ball stop piece 22 formed integrally with the actuating rod is used as the rear side surface of the supply cylinder 18 (the bottom surface when the supply cylinder 18 is in the forward standing state). ) Thus, the protrusion 22a protrudes into the supply cylinder 18 so that the tip end opening 18d of the supply cylinder 18 is closed. The second spring 26 can urge the ball stop piece 22 and the operating rod 21 forward with a force stronger than the force with which the first spring 20 urges the supply cylinder 18 forward. The tension of the first spring 20 and the second spring 26 is set.

  On the other hand, as shown in FIG. 10 as a single unit, 27 is a constant-width plate-like adjusting member, which is a slit-like engagement formed in advance on the substrate 12 as shown in FIGS. By engaging the leading edge 27a and the small protrusion 27b of the adjustment member 27 with the hole 12d and the U-shaped engagement hole 12e, the adjustment member 27 is opposed to the base 18a of the supply cylinder 18 on the lower surface of the substrate 12. Removably attached to the site.

  In the pachinko ball replenishing device configured as described above, the slide plate 7 and the mounting plate 8 are adjusted in the horizontal and vertical positions by loosening and retightening the wing nut 11, and the wing bolt 13 is once loosened and retightened. Thus, the position of the substrate 12 attached to the attachment plate 8 can be adjusted back and forth. For this reason, the height and the front / rear / right / left positions of the supply cylinder 18 and the operating rod 21 of the pachinko ball supply device are adjusted in advance.

  At this time, with respect to a number of pachinko ball replenishing devices provided on the islands, the scale 8i and the above-mentioned scales of the ball replenishing device obtained with good results by testing with one pachinko machine without verifying the set position one by one. By reading the scale 12f and making a note of the setting positions of the mounting plate 8 and the substrate 12, and setting these positions in the same way using these scales as a guide to apply to other pachinko ball replenishing devices as well, The pachinko ball supply device can be easily set to an optimum state. This scale can be set more easily by engraving so that the scale is the same as the pitch of the unevenness of the non-slip portion.

  If there is no such anti-skid part, the ball replenishment device may be displaced due to vibrations transmitted when the pachinko ball moves, but the anti-skid parts 7f, 8d and anti-skid parts 8k, 12b mesh with each other. Therefore, even if the wing nut 11 and the wing bolt 13 are loosened somewhat, it is difficult to be displaced, so that there is no possibility that the ball replenishing device is displaced during use to cause a malfunction.

  In addition, as shown in FIG. 13, in the pachinko ball supply device, when the front frame 5 is opened, the supply cylinder 18 comes to a front standing state due to the tension of the first spring 20, and a pipe line is formed in the supply cylinder 18. The pachinko sphere flows in through 15, and the pachinko sphere is stopped from flowing out by the protrusion 22 a protruding into the supply cylinder 18. In the process of closing the front frame 5, the rear side wall of the ball tank 6 engages with the operating rod 21 as shown in FIG. 13, and the operating rod and the supply cylinder 18 are moved backward against the tension of the first spring 20. As shown in FIG. 14, the tip edge of the bearing body 18f at the base portion 18a of the supply cylinder 18 hits the adjusting member 27, so that the rotation of the supply cylinder to the rear is stopped. It hangs down in the tank 6. Then, when the operating rod 21 is further pushed backward by the rear side wall of the ball tank 6 from this state (the front frame 5 is completely closed as shown in FIG. 15), the operating rod 21 However, the ball stop piece 22 is moved against the tension of the second spring 26, and the protrusion 22a is retracted from the inside of the supply cylinder to open the tip end opening of the supply cylinder. For this reason, the pachinko balls in the supply cylinder are released into the ball tank 6, and this replenishment is continued so that the amount of pachinko balls stored in the ball tank 6 is maintained at a constant level during the game.

  Thus, the angle of the supply cylinder 18 when the pachinko ball is released from the supply cylinder 18 is such that the tip edge of the bearing body 18f at the base portion 18a of the supply cylinder 18 contacts the adjustment member 27. Therefore, as shown in this embodiment, the adjustment member 27 having an appropriate thickness is attached to the lower surface of the substrate 12 so that the angle is finely adjusted to match the situation of the ball tank 6 of each pachinko machine. can do. For this reason, when the front frame 5 is closed, the release time of the pachinko sphere is too early and the pachinko sphere spills out, or even if the front frame 5 is fully closed, the operating tank 21 is sufficient by the ball tank 6. The adjusting member 27 can solve the problem that the pachinko ball is not released without being pressed by the adjusting member 27. As shown in FIG. 16, when the adjustment member is removed, the tip edge of the bearing body 18f at the base portion 18a of the supply cylinder 18 directly contacts the lower surface of the substrate 12, and the rotation stop angle of the supply cylinder 18 is reduced. Become the largest.

  When the front frame 5 is unlocked and the front frame 5 is opened, the operating frame 21 is pressed by the rear side wall of the ball tank 6 when the front frame 5 is slightly opened as shown in FIG. Since the force applied is lost, first, the ball stop piece 22 is returned to its original position by the second spring 26 having a strong tension, and the protrusion 22a protrudes into the supply cylinder 18, whereby the tip end opening 18d of the supply cylinder 18 is closed. For this reason, the release of the pachinko balls in the supply cylinder 18 is immediately stopped, and then the supply cylinder 18 is brought to a front standing state by the tension of the first spring 20, so that the front frame 5 can be opened without fear of the pachinko balls spilling. This makes it easy to open and close the front frame 5 when a failure occurs.

Although not shown, by providing a detector such as a micro switch for detecting the rotation state of the supply cylinder 18 on a part of the substrate 12, the open / close state of the supply cylinder 18 is output to the outside as an electrical signal. can do.
In this embodiment, the first spring and the second spring have been described as being coiled. However, a spring having another shape (equivalent to a member having an elastic restoring force, that is, a spring or an elastic body) may be substituted. it can.

  On the other hand, in another embodiment of the present invention shown in FIG. 17, a nut 27c is fixed to the substrate 12, and an adjusting member 27 comprising a screw shaft is screwed to the nut, whereby the adjusting member 27 is attached to the substrate 12. The leading end of the adjusting member 27 is suspended from the lower surface of the substrate 12 so that the leading edge of the bearing body 18 f corresponding to the base portion 18 a of the supply cylinder 18 can come into contact with the leading end of the adjusting member 18. . In this case, the rotation stop angle of the supply cylinder 18 can be adjusted freely by rotating the adjustment member 27 and appropriately adjusting the length of the tip of the adjustment member 27 protruding from the lower surface of the substrate 12. The supply cylinder 18 can be adjusted so that it always opens and closes at an optimum angle.

In the embodiment shown in FIG. 18, a curved plate-shaped adjusting member 27 having a long hole 27d is attached to the base 18a of the supply cylinder 18 by inserting the screw 25b into the long hole 27d. In this embodiment, the mounting position of the adjusting member 27 can be finely adjusted within the formation range of the long hole 27d by retightening the screw 25b. Therefore, the bearing body 18f is retightened by retightening the screw 25b. The protrusion length from the front end edge of the supply cylinder 18 is adjusted, whereby the rotation stop angle of the supply cylinder 18 when the front end portion of the adjustment member 27 contacts the lower surface of the substrate 12 can be freely adjusted.
As shown in the above embodiment, in the present invention, the adjustment member 27 may be provided on either the substrate 12 or the supply cylinder 18.
