Description of the Related Art Conventionally, in a pachinko hall, for example, a pachinko ball is supplied to a pachinko island, a pachinko ball is moved between a plurality of pachinko islands, a ball lending machine is replenished with a pachinko ball, or a prize ball counting machine. In the case of throwing back the pachinko balls collected in step 2 into the circulation route, a pachinko ball transfer route was necessary. In the transfer, horizontal and vertical transportation and hoisting (and natural lowering) are necessary, and a carrier device and a hoisting device are provided at various places.

As a horizontal conveying means, a conveying path (trough) is inclinedly arranged at a predetermined angle between various devices, but in recent years, a horizontal conveying path is provided between the various devices. A device provided with a power applying device that gives a moving force to a pachinko ball moving along a transport path while being handed over has been put into practical use. As shown in FIG. 17, in the transport path a, a part in which a plurality of rows of balls g, g ... Are juxtaposed by intermediate partition plates c, c. Has been done. In this plural-ball-string transport path a, outer plates e, e are integrally formed on both sides of a substrate b, and intermediate partition plates c, c ... It has become possible to prevent the pachinko balls m from coming into contact with each other and disturbing the ball rows g, g ... And damaging the pachinko balls m.

However, as shown in FIGS.
The arrangement state of the intermediate partition plates c, c ... is such that the inter-face distance f (of the ball arrays g, g ...) of the intermediate partition plates c, c. The width) is larger than the diameter d of the pachinko ball m, and the upward protrusion amount U of the intermediate partition plates c, c ... Is equal to the diameter d of the pachinko ball m. as a result,
As for the moving state of the pachinko ball m on the conventional transport path a, since there are slight lateral gaps j, j between both sides of the pachinko ball m and the partition plates c, c ... The center of the rows g, g ... Does not necessarily roll and move without contacting the inner surface of the intermediate partition plates c, c ... Rather than one of the intermediate partition plates c, c. It comes into contact with and rolls. Therefore, the rolling direction of the pachinko ball m is not only rotation in the traveling direction in the vertical plane but also rotation friction resistance occurs due to temporary contact with the intermediate partition plates c, c.

SUMMARY OF THE INVENTION In view of the problem that it is difficult to stably transfer pachinko balls based on the above-mentioned prior art, the present invention is a partition plate in which the pachinko balls in the adjacent row are not in contact with each other. The center-to-center distance is larger than the diameter of the pachinko ball, and the face-to-face distance of the middle partition plate is smaller than the diameter of the pachinko ball.Furthermore, from the board of the sliding part at the top of the middle partition plate where the pachinko ball rolls in contact. By setting the amount of upward projection lower than the radius of the pachinko ball, by setting each, the pachinko ball rolls only on the substrate of the transport path or on the sliding part of the partition plate,
The above problem is solved by eliminating unnecessary rolling directions. In addition, both sides of the pachinko ball roll on the sliding part of the partition plate or pass above, so that even if the partition plate exists, the increase in the overall width of the transport path is suppressed, It will be narrower than the one.

The inner side) is also satisfied.

An example of actual dimensions under the above conditions will be described. The diameter D of the pachinko ball M is 11 mm and the radius R is 5.5 mm, whereas when the plate thickness T of the inner partition plates 4, 4a ... Is 2 mm, the surface distance FD of the inner partition plates 4, 4a. The center-to-center distance CD of the middle partition plates 4, 4a ... Is 11.5 mm, and the upward protrusion amount UD of the middle partition plates 4, 4a ... Is 2.5 mm. In the case of this embodiment, as shown by the solid lines in FIGS. 2, 3, 4 and 5, when the pachinko balls M are located at the center of the row of balls 5, 5 a ..., The lower end of the pachinko balls M is the surface of the substrate 2. While being placed in contact with and rolling, the lower spherical surface of the pachinko ball M is not in contact with the sliding parts 15, 15a of the intermediate partition plates 4, 4a ... At a certain moment during rolling of the pachinko ball M, the pachinko ball M is positioned not on the center of the ball row 5, 5a ... It contacts the sliding parts 15, 15a of the plates 4, 4a .... Even in this case, the pachinko balls M in the adjacent row of balls 5, 5a ... Are non-contact because there is a gap of about 0.4 mm.

In the following, the whole and partial functions of the above-described embodiment will be described, and the essential conditions, changeable conditions, and shapes of the basic configuration will be described. First, in the case of the size of the above embodiment, when the pachinko ball M is located at the center of the row of balls 5, 5a ... And rolls on the substrate 2 in the transfer direction,
The lower spherical surface of the rolling pachinko ball M is the partition plate 4, 4a ...
The non-contact with the sliding parts 15 and 15a in FIG. Also, when the pachinko balls M are positioned on both sides of the row of balls 5, 5a ... And roll on the substrate 2, the lower spherical surface of the pachinko balls M comes into contact with the sliding parts 15, 15a and moves laterally. The pachinko balls M in the adjacent row are also not in contact with each other. Due to these two types of rolling conditions, pachinko balls M
The lower end of the ball constantly rolls on the substrate 2, and the lower spherical surface of the pachinko ball M is temporarily a row of balls 5, 5a ...
The rolling parts 15 and 15a on the top part 14 of 4a ... Contact and roll.

When rolling on the tops 14 (sliding portions 15, 15a) of the intermediate partition plates 4, 4a ... In a non-contact manner, frictional resistance that does not require contact rotation in directions other than the transfer direction does not occur. Even when the pachinko balls M temporarily contact the tops 14 (sliding parts 15, 15a) of the partition plates 4, 4a, the contact point of the pachinko balls M is the lower spherical surface. Rotational resistance does not occur alone, but rotational resistance in the moving direction also occurs at the same time. Therefore, in comparison with the conventional rotational resistance only in the horizontal plane, the sliding part 1 is
5 and 15a serve as a rotation supporting surface in the moving direction, and the moving force is not relatively reduced.

The conditions for achieving the above-mentioned rolling state (the state of rolling mainly on the substrate 2) are also related to the plate thickness T of the intermediate partition plates 4, 4a ..., The center distance CD, and the face distance FD. However, it also relates to the upward protrusion amount UD of the intermediate partition plates 4, 4a .... That is, when the upward protrusion amount UD of the top 14 of the intermediate partition plates 4, 4a ... Is set to be larger (higher) than that of the embodiment, the following 2
There are modes. 1 with the upward protrusion UD set slightly higher
In the second mode, as shown by the solid line in FIG. 6 (the one-dot chain line in FIGS. 1 to 5), the lower end of the pachinko ball M contacts the surface of the substrate 2 and the lower spherical surface of the pachinko ball M is a partition plate. The sliding parts 15, 15a on the tops 14 of the parts 4, 4a ... Also come into contact, and the pachinko balls M are supported at three points. Further, although not shown, as a second mode in which the upward protrusion amount UD is set to be higher, the lower spherical surface of the pachinko ball M is the partition plates 4, 4a ...
The pachinko ball M is in contact with and supported by the sliding parts 15 and 15a at the top 14 of the pachinko ball M, and the lower end of the pachinko ball M is not in contact with the surface of the substrate 2 and the pachinko ball M has two points on the left and right sliding parts 15 and 15a. Be supportive.

Therefore, the rolling contact state of the pachinko balls M differs depending on the amount of upward protrusion UD of the intermediate partition plates 4, 4a ..., For example, the height difference of 0.1 to 0.2 mm, and the desired rolling state. To set, for example, the row of balls 5, 5a
The lower spherical surface of the rolling pachinko ball M is such that the lower end of the rolling pachinko ball M contacts the surface of the substrate 2 or when the pachinko ball M is located in the center of the row of balls 5, 5a. The intermediate partition plates 4, 4a ... In order not to be in contact with the top 14 of the intermediate partition plates 4, 4a, or so that the lower spherical surface of the pachinko ball M is always in contact with the sliding parts 15, 15a. It is necessary to set the upward protrusion amount UD of the top 14 of the. Incidentally, the intermediate partition plate 4,
The amount of upward protrusion UD of the top 14 of 4a is too small (low)
Then, since the lateral movement of the pachinko balls M is less restrained, the projections of the tops 14 of the partitioning plates 4, 4a, ... upward so that the pachinko balls M of the adjacent row of balls 5, 5a. Amount U
It is also necessary to set the minimum amount of D.

Next, the shapes of the sliding parts 15, 15a at the tops 14 of the intermediate partition plates 4, 4a ... Which the lower end spherical surfaces of the pachinko balls M contact will be described. Example above (FIGS. 1-5 and 6)
Then, the tops 14 of the intermediate partition plates 4, 4a ... Have a triangular cross section, and the sliding surface 15 where the lower end spherical surface of the pachinko ball M contacts the vertical surface of the intermediate partition plates 4, 4a. , 15a, but the sliding part 1 formed on the top 14 of the partition plates 4, 4a ...
The shapes of 5 and 15a can be changed appropriately. For example, top 1
In the embodiment of FIG. 1 in which 4 is a triangle, the corners of the vertical plane and the horizontal plane may be formed as the sliding portions 15 and 15a as shown in FIG. Further, in the above-mentioned embodiment, the sliding parts 15, 15a are formed as lines in the transfer direction, but as shown in FIGS.
A may be formed as a surface, and in FIG. 8, the sliding portions 15, 15a are formed as inclined surfaces, and in FIG. 9, the sliding portions 15, 15a are formed as curved surfaces. Similar to the embodiment of FIG. 6, in FIGS. 7 to 9, the solid line is above the top 14 of the intermediate partition plates 4, 4a ... so that the lower end spherical surface of the pachinko ball M is always in contact with the sliding parts 15, 15a. Projection amount UD
Is set high, and the pachinko ball M is set to 3 along with the surface of the substrate 2.
7 to 9 show a state of being supported by a point, and the one-dot chain line in FIGS. 7 to 9 shows the substrate 2 when the pachinko ball M is located in the center of the ball row 5, 5a.
It shows a case where the upward protrusion amount UD of the intermediate partition plates 4, 4a ... Is set so as to be supported only by.

Next, an example of use of the pachinko ball conveying path according to the present invention as a horizontal rail will be described.
The transport path 1 can of course be used in other than this usage example.
As shown in FIGS. 12 and 13, the transport path 1 is installed between the downstream (upper end) of the pumping paths 20 and 20a and the upstream (upper end) of the supply paths 21 and 21a installed on the pachinko island S or the like. That is, the transport path 1 is installed between the hoisting paths 20 and 20a of one pachinko island S and the supply paths 21 and 21a of the other pachinko island S. In addition, pumping path 2
0, 20a, supply paths 21, 21a, etc. are installed inside and outside the ball storage tank TQ for pachinko balls M. Then, as shown in FIGS. 10 and 11, at the supply side end of the transport path 1, the respective ball rows 5 and 5a are provided.
Supply guide 22 that can drop and supply pachinko balls M to the end of
The supply guide 22 is a 90-degree arc-shaped gutter, and the upper end of the supply guide 22 is connected to the lower end of the ball receiving tank 23. Further, as shown on the right side of FIGS. 12 and 13, the ball receiving tank 23 is connected to the ball storage tank TQ from the pumping paths 20, 20a.
It is designed to supply pachinko balls M via. Reference numeral 24 denotes a ball feeding device, which is housed in a device box 25 attached to the pumping paths 20, 20a (ball storage tank TQ) attached to a part of the pachinko island S. That is, the feed roller 27 is arranged so that the outer circumferential feed surface 28 of the feed roller 27 rotated by the operation of the motor 26 is substantially aligned with the inner circumferential surface of the supply guide 22, and the urethane outer circumferential feed surface of the feed roller 27 is arranged. 28 are the respective balls 5, 5a ...
Are arranged so as to come into contact with the pachinko balls M on the end side of.

The feed roller 27 and the motor 26 are mounted so that their positions can be adjusted by a slight amount, and the pressure contact state between the pachinko balls M and the outer peripheral feed surface 28 of the feed roller 27 can be adjusted. Further, the motor 26, the feed roller 27 and the like are also arranged in the apparatus box 25 in the same manner as the supply side end of the conveying path 1, the supply guide 22 and the like.

As shown on the left side of FIG. 13, the discharge path end of the transport path 1 is also attached to the supply path 21 attached to the coin storage tank TQ.
The pachinko balls M, which are connected to the conveying path 1 and are transferred to the conveying path 1, can be supplied to the supplying paths 21 and 21a.

In the case of this use example, the conveyance path 1 is set on the pachinko island S.
Since the pachinko balls S are horizontally arranged and used in between, in order to maintain the pachinko balls M in the pachinko island S at a predetermined amount, both the inflow side and the outflow side are installed for each pachinko island S. As the installation method, they may be arranged in parallel as shown in FIGS. 13 and 14, or may be arranged in upper and lower two stages as shown in FIG.

According to this example of use, the outer peripheral feed surface 28 of the feed roller 27 rotated by the operation of the motor 26 is
The pachinko balls M pressed in 22 are sent in the transfer direction,
As a result, the pachinko balls M of the ball rows 5, 5a ... In the transport path 1 are sequentially pushed forward in the transfer direction, and are supplied from the transfer discharge end (outflow end) to the supply paths 21, 21a and the ball storage tank TQ.

The feed roller 27 is a cylindrical outer peripheral feed surface.
Although the one having 28 has been described, as shown in FIG. 16, an accommodating recess 30 capable of accommodating and pushing out the upper half of the pachinko ball M may be cut out on the outer periphery.

The details (including conventional techniques, problems, etc.) when the transport path 1 according to the present invention is applied to the above-described use examples will be described below. Conventionally, a slant gutter has been arranged on the pachinko island S as a means for supplying the pachinko balls M to the pachinko island S. In order to allow the pachinko balls M to be interchanged in the pachinko island S, two inflow and outflow sides are required in the pachinko island S, and two inclined gutters are required to have opposite inclinations. Therefore, the appearance of the ceiling of the pachinko hall was impaired. Further, there is a problem that it takes time to transfer the pachinko balls M by natural rolling due to the inclination, so that a large amount of pachinko balls M cannot be transferred quickly. For this use case,
By arranging the transport path 1 horizontally, the appearance of the ceiling of the pachinko hall can be improved, and the pachinko balls M can be forcibly sent for quick transfer processing.

[0027]

In summary, according to the present invention, in the conveying path 1 for pachinko balls M, a plurality of rows of balls 5, 5a ... Are juxtaposed by the intermediate partition plates 4, 4a ... Arranged in the longitudinal direction on the substrate 2. As a result, since the pachinko balls M to be conveyed are conveyed in rows in the row of balls 5, 5a ..., the pachinko balls M of adjacent rows of balls 5, 5a ... Do not come into contact with each other, and the transfer speed is stable. In addition, the pachinko ball M can be prevented from being damaged. or,
Since the center-to-center distance CD of the partition plates 4, 4a ... Is set to be larger than the diameter D of the pachinko balls M, it is possible to prevent the pachinko balls M in the adjacent row from contacting each other, and the partition plates 4, 4a.
Since the face-to-face distance FD is set to be smaller than the diameter D of the pachinko ball M, the horizontal plane end that passes through the center of the pachinko ball M (the end of the pachinko ball M in plan view) is the intermediate partition plate 4, 4a ...
The partial width of the transport path 1 can be reduced by partially locating the upper part of the transport path 1. Further, since the upward protrusion amount UD of the sliding portions 15, 15a of the tops 14 of the partitioning plates 4, 4a ... on which the pachinko balls M roll by contact is set lower than the radius R of the pachinko balls M, the pachinko balls M are set. M is a partition plate 4, 4a
The portion that comes into contact with the pachinko ball M is not the spherical surface that intersects the horizontal plane passing through the center of the conventional pachinko ball M but the lower spherical surface of the pachinko ball M, so that the pachinko ball M to the partition plates 4, 4a.
Or the pachinko ball M slides on the sliding parts 15 and 15a.
When rolling over, the conventional rotation in the horizontal plane is relatively reduced and the rotation in the vertical plane in the moving direction is increased to reduce the movement resistance and stabilize the movement speed. You can Even if the pachinko balls M fed to the inflow end of the transport path 1 are located in front of the intermediate partition plates 4, 4a ..., the top 14 of the intermediate partition plates 4, 4a ...
Since it comes into contact with the lower spherical surface of the, the contact state is extremely unstable, so that the pachinko balls M at the front end of the intermediate partition plates 4, 4a ... It is pressed and flows in, and pachinko balls M enter all the ball rows 5, 5a ....
Can be flowed in very easily. As a result, it is not necessary to arrange the pachinko balls M just before flowing into the conveyance path 1 in accordance with the intervals of the ball rows 5, 5a ..., Therefore, the pachinko balls M are arranged by the supply guide 22, the feed roller 27, etc. on the upstream side of the conveyance path 1. No tools, guides, etc. are required, and the supply / delivery device can be simplified.

The lower end of the rolling pachinko ball M is the substrate 2
When the pachinko balls M move at three points of the sliding parts 15 and 15a and the substrate 2 so as to come into contact with the surface, or when the pachinko balls M move on the substrate 2, the amount of upward protrusion of the top 14 of the intermediate partition plates 4, 4a Since the UD is set, most of the weight of the pachinko balls M is supported by the substrate 2 having a large plate thickness T, and the load on the intermediate partition plates 4, 4a ... Is reduced and the durability of the transport path 1 is improved. You can

Also, as shown in the dimensions of the embodiment, pachinko balls M
Of the inner partition plates 4, 4a ... so that the lower spherical surface of the rolling pachinko ball M is not in contact with the top 14 of the inner partition plates 4, 4a. Since the upward protrusion amount UD of the top 14 is set, the weight of the pachinko ball M is basically supported by the substrate 2, and when the pachinko ball M deviates from the center, it makes contact with the top 14 of the partition plate and rolls. Therefore, the pachinko ball M can be stably rolled and moved.

Further, the upward protruding amount UD of the top 14 of the intermediate partition plates 4, 4a, ..., so that the pachinko balls M in the adjacent row are not in contact with each other.
Since the minimum amount is set, it is possible to reliably prevent the pachinko balls M from coming into contact with each other due to the top 14 of the partitioning plate being too low.

Further, the sliding portion of the top portion 14 of the intermediate partition plates 4, 4a ...
15 and 15a are formed as corners or the tops of the partition plates 4, 4a ...
Since the runners 15 and 15a of 14 formed the ridgeline, the runners 15 and 15a
When the pachinko ball M comes into contact with a, its frictional resistance can be minimized, and the sliding parts 15, 15a of the top 14 of the partition plates 4, 4a ... Board 4, 4a
Since the sliding parts 15 and 15a of the top part 14 of ... have curved surfaces, the intermediate partition plates 4 and 4a on which the pachinko balls M abut are planar parts, so the sliding parts 15 of the intermediate partition plates 4 and 4a ... The wear deformation of 15a does not occur and the durability can be improved.

Further, since the conveying path 1 for transferring the pachinko balls M among the various devices is horizontally arranged, the aesthetic appearance of the pachinko hall ceiling can be improved.

Further, since the supply guide 22 for dropping and supplying the pachinko balls M is provided at the end of the ball trains 5, 5a ..., The pachinko balls M can be continuously transferred, and the ball trains 5, 5a ... Feeding device 24 that feeds the pachinko balls M sent to the end of the
Since it is provided, it is possible to forcibly send out the pachinko balls M and quickly transfer a large amount of the pachinko balls M.

Further, since the transport path 1 is arranged between the pachinko islands S, it is possible to easily maintain a predetermined amount of the pachinko balls M in the pachinko islands S, and the pachinko balls M are provided on the respective pachinko islands S. Lifting paths 20 and 20a for vertically moving and supply path 21,
Since each of the 21a is provided, it is possible to transfer a large amount of pachinko balls M that have been interchanged between the pachinko islands S to the necessary locations on the pachinko island S or to prepare for the transfer to another pachinko island S at one place. In addition, two conveying paths 1 and 1 are provided between the hoisting paths 20 and 20a of one pachinko island S and the supply paths 21 and 21a of the other pachinko island S, respectively. Since the transfer direction is the opposite direction, flexible transfer between the pachinko islands S can be performed in both directions and between all the pachinko islands S.

Further, since the ball feeding device 24 for pushing out the pachinko balls M by the feed rollers 27 rotated by the motor 26 is formed, the pachinko balls M are pressed into contact with the feed rollers 27 and fed out, so that a large amount of the pachinko balls M are surely carried out. Can be sent out,
Further, since the outer peripheral feed surface 28 of the feed roller 27 is provided with the accommodation recesses 30 arranged in a horizontal row, the pachinko balls M are fed by the feed roller 27 into the accommodation recess 30 of the outer peripheral feed surface 28 to further enhance the strength. The pachinko ball M can be sent out to the outside, which is a great practical effect.
