2. Description of the Related Art Conventionally, in a pachinko ball gutter, various proposals of this kind have been made, such as making the bottom of the gutter a mushroom shape as a means for eliminating obstacles caused by fine dust and small foreign matter mixed into the ball. However, in order to streamline management and provide customer service, modern amusement arcades will be equipped with a thin automatic ball-lending machine between pachinko machines installed adjacent to Shimadai, and collect coins inserted in the ball-lending machine collectively. In this case, the coins inserted into the ball rental machine accidentally fell to the lower part of the island stand during transportation, etc., and the recovery ball flowing in the recovery gutter flowed down as a transfer force and flowed into the lifting lift In such a case, it may adversely affect the immediate lifting mechanism and cause a failure, and if lifted, it may become an obstacle to block the replenishment path on the island platform, causing a major trouble. In addition, it is difficult to solve the trouble because the inside of the island is almost closed, and in the case of the bottom of the gutter proposed above, it is very difficult to remove the coins out of the gutter because the coins are often horizontal. is there. Further, there is a drawback that, when the foreign matter mixed into the ball, for example, the mounting screw used in each device and the device is loosened and dropped, only the one having a size within the interval of the saw blade can be removed.

The present applicant has proposed Japanese Utility Model Publication No. 60-10613 to solve the above-mentioned problem. According to this disclosed technique, a plurality of substantially triangular-shaped partition walls having the same shape are erected to form a plurality of spherical passages, and the starting end thereof is formed in a mushroom shape at the bottom of the spherical passage, and is connected to the mushroom groove. A pachinko ball gutter is constructed by forming a bridge path and forming a sorting path that is an open groove that spreads largely in the lateral direction around the bridge path. In order to discharge foreign substances such as coins out of the gutter, the partition wall is formed in a stepped shape. However, as a means for providing this partition wall in a stepped manner, since the rising portion of the partition wall of the same shape is provided to be shifted back and forth with respect to the longitudinal direction of the pachinko ball gutter, the pachinko ball gutter naturally becomes long, For example, if the gutter is provided with a gradient between the lifting lift and the storage tank for allowing the balls to flow into the lifting lift (so that the storage tank side is higher), the interval between the lifting lift and the storage tank is increased. As the length of the storage tank increases, the end of the pachinko ball gutter on the storage tank side rises accordingly, and the bottom surface of the storage tank rises accordingly, resulting in a problem that the capacity of the storage tank eventually decreases. Especially in amusement arcades where it is desired to play a large number of prize balls temporarily due to the needs of customers in the near future, as many balls as possible are stored in storage tanks to secure the amount of balls used for pachinko games. There was a request to do so, and early improvement was desired.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned inconvenience, and an object of the present invention is to align balls flowing down in a short distance section and quickly guide the balls to a mouth of a lifting machine. At the same time, foreign objects such as coins and screws mixed into the ball are forcibly discharged outside the gutter in a short distance section, and the capacity of the storage tank is increased to make effective use of the limited space on the island stand. In providing a foreign matter discharge path.

[0005]

In order to achieve the above-mentioned object, a foreign matter discharge path in a pachinko ball gutter according to the present invention is formed by erecting a plurality of partition walls and side walls to form a plurality of ball passages. On the bottom of the ball passage, a bridge having a minimum necessary width is provided at an appropriate section of the ball passage through which the ball and the upright coin can pass, at the center in the longitudinal direction of the ball passage, and both walls of the ball passage are provided. The partition wall or the lower part of the side wall to be removed is formed in a range that does not hinder the passage of the sphere to form a separation path having an open bottom, and the partition wall is provided in a substantially right-angled triangular shape, and an inclined portion serving as a hypotenuse is provided. The present invention is characterized in that adjacent partition walls are formed at different inclinations.

[0006]

[Operation] Therefore, according to the foreign matter discharge path in the pachinko ball gutter of the present invention, the spheres flowing down in a plurality of steps in a short distance section are divided and aligned, and are quickly led out to a lifting lift or the like and mixed with the spheres. The coins and the like can be stood up and removed reliably, and the gutter main body can be formed short. Therefore, for example, even if a gradient is provided between the lifting lift and the storage tank, the position of the gutter start end on the storage tank side serving as a ball introduction port becomes low due to the short configuration, and the storage tank has a structure. It is possible to increase the capacity by forming the upper surface to be deep and the entire length to be long, so that the limited space at the waist in the island can be effectively used.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The foreign matter discharge path in the pachinko ball gutter of the present invention is roughly classified into a passage means for allowing passage of a ball, a sorting means for removing foreign matter such as coins, and a coin having a horizontal appearance mixed in a ball flow path. It consists of foreign body sliding means forcibly making it stand up,
In addition, the ball sliding means facilitates alignment of the stepped ball and aligns the ball in a short-distance section both in a section that is biased to facilitate foreign substance discharge and a section that also serves as foreign substance discharge while returning the flow force. First, the configuration of the sorting means will be limited to a single row of paths based on the drawings and will be described in detail.

The interval between the ball passages 2 of the gutter 1 allows the passage of the ball diameter + the thickness of the coin, and the bridge 3 having the required minimum width through which the center of gravity of the ball passes the appropriate distance from the bottom of the section A of the passage 2 is formed as a ball. The passage 2 is erected at a central position in the longitudinal direction and fixed by appropriate means. Bridge section 3 forms an A section in a series of a substantially front half E section and a substantially rear half F section shown in FIG. 3, and a ball contact surface at an upper edge thereof has a C-shape as shown in FIG. The section F is a flat section 1 shown in FIG.
0 each. FIGS. 5 and 6 are cross-sectional views taken along lines AA and BB in FIG. 3, respectively. Reference numeral 5 denotes a substantially rectangular side wall, and reference numeral 6 denotes a substantially right-angled triangular partition wall for limiting the ball passage 2 to the above-mentioned interval. Section C of the both walls 5, 6 shown in FIGS. (Appropriate distance within the section A) of the ball passage 2 at the lower part in the longitudinal direction of the ball passage 2 in the cross-section of the ball passage 2 to eliminate the maximum band-like interval that does not hinder the passage of the ball, and to expand substantially in the lateral direction around the bridge 3 A sorting path 8 having an open bottom 7 is formed. The sorting path 8 is a path for discharging foreign substances such as coins from the open bottom 7 to the outside of the gutter 1. A boundary 13 between the C-shaped part 9 and the plane part 10 is located at a substantially central part in the longitudinal direction. The C-shaped section 9 section always forms a play space S shown in FIG. 5 in which a ball is slidably held at a vertex portion and a bottom corner portion of the partition wall 6 so as to be offset, and foreign matter such as coins drop. . The flat part 10
The section is a place where the falling velocity of the ball, which has slowed down in the C-shaped section 9, is restored in a short distance, and a large number of balls are quickly and discharged to a lifting lift or the like.

The section B is a section for guiding and aligning the introduced spheres and leading them out to the section A. The thin rectangular guide piece 4 is provided with an interval K smaller than the ball diameter shown in FIG. 1 A taxiway 14 laid on the bottom surface and the ball passes through the center in a substantially
Is formed, and a D section to be described later, which is connected to the B section and is a starting end of the bridge road 3, is formed. If necessary, the upper surface of the terminal end of the bridge 3 may be formed in a substantially concave shape so that the ball can pass through the center of the ball passage 2 and be led out to a lifting lift or the like.

[0010] Next, the structure of the foreign matter sliding means will be described in detail. To begin with, the rising portion starts from the leading end of the section D at an appropriate distance in front of the sorting path 8 and is provided with a slope to face the upper part of the sorting path 8.
(The oblique side of the partition wall 6) is formed, and a vertical coin locking portion 12 is provided at the upper limit of the inclined portion 11. This coin lock 12
Is a member that finally brings the coins in the horizontal form flowing on the inclined portion 11 into contact with each other and drops them into the ball passage 2, and a short locking portion 12a connected to a high wall 6a and a low wall 6b, which will be described later, It is formed alternately with the length locking portion 12b, and is provided slightly above and forward from the end of the sorting path 8. The inclined portion 11 is formed by setting the inclination angle of the adjacent partition wall 6 such as the high wall 6a and the low wall 6b in the partition wall 6 shown in FIGS.
a, the gentle slope 11b and the upper limit are formed alternately with a difference in upper limit height, and the upper end slope is formed in a substantially mountain shape so that foreign substances such as coins are quickly shaken to the left and right. Also, the inclined portion 11
In section D, a short distance adjustment section in which a plurality of steps of flowing spheres are almost equally distributed is such that the inclination angles of the high wall 6a and the low wall 6b are the same as those of the gently inclined portion 11b. The spherical path 2 is formed in an alternately stepped shape by the substantially inverted substantially U-shaped high wall 6a and the equally inclined low wall 6b shown in FIGS. Also,
A detachable lid 15 is formed to cover a section from the coin locking portion 12 to the end of the partition wall 6 from above.
The long groove provided on the lower surface of the partition wall 5 is fitted to the upper edge of the partition wall 6. The lid 15 is a member that prevents deformation of the gutter 1 due to distortion or the like, prevents dust such as fine dust from dropping at the end of the ball passage 2, and maintains a smooth ball flow.

Next, the operation of the present invention will be described. First, in a normal case, the spheres flowing down the gutter 1 in a plurality of steps are arranged such that, in the section B, the first-stage aligned balls pass through the center of the taxiway 14 shown in FIG. It travels along the first-stage sphere at random, flows into the section D shown in FIG. 2, and forcibly aligns and flows down into each of the passages 2 and 2 at the gentle slope 11b on the upper surface of the partition wall 6. Interrupted from above between the spheres of the tier, it was accurately diverted and aligned while decelerating. When there was a sphere of the third tier, after climbing on the steep slope 11a, the ball was energized. The ball falls on the sphere that flows down in a row, interrupts between the spheres with flow, and flows down vigorously while being sandwiched.

FIG. 3 is a plan view C showing the sorting path 8.
In the approximately first half of the section, the cross-section of the bridge 3 is a substantially C-shaped portion 9 shown in FIG. 5 and the ball slides down with one of the left and right walls 6a and 6b offset. A play space S is formed on the opposite side, and the play space S facilitates the reception of the interrupting ball falling from above, prevents deceleration of the falling force, and shakes off foreign substances (coins, screws, etc.) mixed in the ball. Next, the sphere that has passed through the boundary 13 of the section C reaches the plane portion 10 of the cross section of the bridge 3 shown in FIG. 6, and the sphere is returned from the bias by the characteristic of rolling at the central portion of the sphere passage 2 at a portion having a large diameter. And go straight down.

The case where a coin is mixed in a ball will be described in detail in two cases. When a coin is mixed in a falling ball in an upright state,
It falls down on the separation path 8 of the open bottom 7 on both sides of the bridge 3 shown in FIG. In this case, the distance between the two passages is equal to the diameter of the ball plus the thickness of the coin, so that the ball and the coin can pass in parallel at the same time. Next, when the coin is moved downward by the force of the ball in the horizontal state, the coin is pushed up on the slope 11 of the section C, and the coin in the seesaw shape falls down to one of the ball passages 2 and stands up. At the opening bottom 7 immediately below the gutter 1 to be discharged to the outside of the gutter 1 or removed as described above. The inclined portion 11 of the partition wall 6 is formed to have a mountain-shaped cross section, and foreign matter sliding means is provided to make it easy for coins to stand up.
The upper C-shaped portion 9 makes the coin fall smoothly.

In another embodiment, the horizontal coin is a steeply inclined portion 1.
In the case of a bridge between 1a and the gentle inclined portion 11b, if the ball competes on the gradient by the force of the ball without standing,
Due to the step between the high wall 6a and the low wall 6b in the section C, the coin which has quickly fallen into the right or left ball passage 2 in an upright posture, and further pushed up to a position where it does not hinder the flow of the ball regardless of the drop means, Then, the obstacle is substantially stopped on the inclined portions 11a and 11b until the obstacle of the ball passage 2 is eliminated and the ball path 2 rises and falls due to vibration or the like. The locking portion 12 limits the progress of coins on the inclined portion 11, and makes the falling of the coin earlier by contacting the locking portion 12. The sorting path 8 is not limited to the removal of coins, needless to say, and discharges all screws and missing balls in the area of the open bottom 7.

In this embodiment, the coin locking portions 12 are formed so as to be linearly parallel to each other. However, the length of each partition wall 6 is changed so that each of the adjacent locking portions 12 has a substantially uneven shape. In this case, the coin can be quickly raised, but the present invention is not particularly limited to this configuration.

As is apparent from the above description, the foreign matter discharge path in the pachinko ball gutter of the present invention can be very easily provided at an appropriate place in the pachinko flow gutter, and a plurality of steps in a short distance section. The spheres flowing down in the form of a flow are divided and aligned and quickly led out to a lifting lift or the like, and the sorting path 8 is formed with a stepped partition wall 6 (6a, 6a,
6b), it is possible to remove large foreign matter, and coins and the like mixed in the ball can be reliably removed by standing up. For example, a slope is provided between the lifting lift and the storage tank to interpose. However, since the gutter 1 body is formed short,
The position of the gutter start end on the storage tank side, which is the ball introduction port, is lowered, so that the storage tank can be formed deeper and longer in overall length to increase its capacity due to its structure, and the waist of the island is limited. The space can be used effectively, the cause of intentional influence on the replenishment of balls and related equipment is eliminated at an early stage, the functions are smoothed, the maintenance work is remarkably omitted, and the economy is exhibited.

The above is one embodiment according to the present invention,
It goes without saying that the design can be freely changed within the scope of the utility model registration claim.

[0018]

[Effects of the Invention] As is apparent from the above description, the foreign matter discharge path in the pachinko ball gutter of the present invention shunts the balls flowing down in a plurality of steps in a short distance section and quickly lifts the lift. In addition, coins and the like mixed into the ball can be raised and reliably removed, and the gutter main body can be shortened. Therefore, for example, even if a gradient is provided between the lifting lift and the storage tank, the position of the gutter start end on the storage tank side serving as a ball introduction port becomes low due to the short configuration, and the storage tank has a structure. It is possible to increase the capacity by forming the upper surface to be deep and the entire length to be long, so that the limited space at the waist in the island can be effectively used.
