Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a box overturning device for overturning a box such as a game medium containing box for containing game media such as a pachinko ball and a slot machine coin, and a game medium counting device including the box overturning device. .
[0002]
[Prior art and problems to be solved by the invention]
A storage box containing a large amount of game media such as pachinko balls and coins for slot machines is placed on the game media counter, and the storage box is turned over to discharge the game media into the slot of the game media counter. The work to be performed is not always easy in the recent increase in the size of the storage box, and game media are likely to be scattered to the periphery if care is not taken.
[0003]
As a solution to this problem, a part of the bottom part of the pachinko ball box can be opened by pushing up a predetermined place, and a ball box support part and a bottom part push-up projection are provided at the input port of the pachinko ball counting device. The pachinko ball box and the pachinko ball count are designed so that if the pachinko ball box is placed upright at a predetermined position of the counting device, a part of the bottom of the ball box is opened so that the pachinko ball can flow down from the opening. The device is known.
[0004]
However, in this case, a special mechanism is required not only for the pachinko ball counting device but also for the pachinko ball box that is used and consumed in large quantities. Therefore, the cost of the ball box increases, and the portion of the bottom opening mechanism is difficult to clean, so dirt easily accumulates there, so the pachinko ball capacity is reduced compared to the size of the ball box because of the mechanism, Further, the target game media are limited to spheres such as pachinko balls that can flow smoothly from the opening at the bottom of the ball box, and slot machine coins are not eligible.
[0005]
The present invention has been made in view of the above-mentioned problems existing in the prior art, and the object thereof is a box containing a large amount of game media such as pachinko balls and slot machine coins. A box overturning device that does not require a special mechanism in the target box, and that allows the game medium to be discharged from the body to a fixed place such as a slot of the game medium counting device easily and reliably. It is providing the game media counting device provided with the apparatus.
[0006]
[Means for Solving the Problems]
The box overturning device of the present invention that achieves the above object is
A box body overturning device for overturning a box body having a downward projecting portion on the outer peripheral part of the bottom part from a substantially upright state,
A bottom support for supporting the bottom of the box;
A rear side support that is located at the rear of the bottom support and supports the rear side of the box from the rear;
A rear upper edge support for supporting the upper rear edge of the box from above;
A claw portion for supporting the downward projecting portion located at the rear of the box from the front side,
Supported to rotate integrally around the horizontal rotation axis,
As the bottom support that supports the bottom of the substantially upright box rotates backward about the rotation axis and the box falls backwards, the rear side and rear top of the box The edge part is supported by the rear side support body and the rear upper edge part support body, and the downward projecting portion located at the rear part of the box body is supported by the claw part, so that the box body falls backward. Is prevented.
[0007]
The substantially upright state of the box is sufficient as long as the object accommodated in the box does not almost spill, and may be inclined to some extent.
[0008]
The lateral direction is a direction that is substantially horizontal and substantially perpendicular to the front-rear direction.
[0009]
In the case of supporting the rear side of the box from the rear side, supporting the rear upper edge of the box from the upper side, and supporting the downward projection from the front side, the rear upper edge from the rear side and the rear side , From the top, from the bottom, and from the front, so to speak, is an expression based on the coordinate axes fixed to the box in an upright state, respectively. Even in the process in which the box falls backward, it does not change with respect to the box itself.
[0010]
The nail | claw part should just be what can support the downward protrusion part located in the rear part of a box from the front side, The shape is not specifically limited.
[0011]
When a box body having a downward projecting portion on the outer periphery of the bottom portion is placed on the bottom support body in an almost upright state, and the bottom support body is rotated backward about the rotation axis, the box As the body falls backwards, the rear side of the box is supported from the rear side by the rear side support, and the rear upper edge of the box is supported from the upper side by the rear upper edge support. The body rotates rearward, gets over the rear side support and rear upper edge support and tries to fall back. At that time, since the downward projecting portion located at the rear portion of the box is supported from the front side by the claw portion, the rear rotation of the box is prevented and the rearward drop-off is prevented.
[0012]
When the range in which the bottom support can rotate is between the state in which the supporting box tilts slightly rearward and stands upright and the state in which the box supports falls, the box is supported by the bottom support. The rear side portion is supported from the rear side by the rear side support body, and the downward projecting portion located at the rear portion of the box body can be easily supported from the front side by the claw portion. In particular, when the bottom support is positioned at a rotation angle at which the box to be supported is substantially upright, the claw portion does not substantially protrude toward the bottom of the box, and such a state is easily achieved. In addition, since the bottom support does not rotate more than necessary, there is no need for extra operation, and unexpected dropout of the box can be prevented.
[0013]
When the bottom support is positioned at a rotation angle at which the supporting box is almost upright, the claw does not substantially protrude toward the bottom of the box, and the supporting box is in a fallen state. It is desirable that the claw portion is supported so as to protrude substantially toward the bottom portion of the box body before the bottom support body reaches the rotational angle position. The bottom support is positioned at a rotation angle at which the supporting box is almost upright, and the box is made the bottom support with the rear side of the box supported from the rear side by the rear support. When supporting and when removing the box from the bottom support at the rotation angle position, the claw does not substantially protrude toward the bottom of the box, so that the claw does not interfere with the work.
[0014]
The claw portion is provided in a part of the claw member that swings around a fixed swing axis with respect to the bottom support body, and the position of the swing axis rotates so that the supporting box body is substantially upright. If the bottom support is positioned at an angle, the claw will not protrude substantially toward the bottom of the box, and the nail will be moved before the bottom support reaches the pivot angle where the supporting box will fall. The part can be a position that protrudes substantially toward the bottom of the box.
[0015]
When the plurality of claw portions that perform the protruding operation independently are provided at different positions in the lateral direction and / or the front-rear direction, even if the position of the downward protruding portion differs depending on the type and placement of the box, There is a high probability that any of the claw portions can support the downward projecting portion located at the rear portion of the box from the front side.
[0016]
The game medium counting device of the present invention comprises the above-mentioned box overturning device.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings.
[0018]
FIG. 1 to FIG. 4 relate to a ball counting device for pachinko balls as an example of an embodiment of a game medium counting device provided with a box overturning device of the present invention. FIG. 1 and FIG. FIG. 3 is a plan view, and FIG. 4 is a front view.
[0019]
The ball counting device 10 has a box overturning device 12 on the upper front side, and a ball insertion port 14 having an upper opening on the upper rear side. Pachinko balls thrown from the ball slot 14 are counted and discharged from the rear. The counting result is displayed on the upward projecting display portion 16 provided on the rear side of the ball insertion slot 14 together with necessary information such as the number of prizes. The surplus balls after the prize exchange can be returned to the player from a surplus ball return port 18 provided on the right side of the front surface. Note that the game medium counting device of the present invention may be for game media other than pachinko balls, such as coins for slot machines.
[0020]
The ball box 20 represented by a two-dot chain line (which can also be used for coins) has a flat rectangular shape, and the upper edge portion 20a is formed and reinforced with a thick wall portion protruding slightly outward. ing. In addition, the ball box 20 has a handle 20b at the upper part of the left and right side surfaces, and has a downwardly extending ridge 20c that serves as a support leg over the entire outer periphery of the bottom. In addition, the downward protrusion part which the box which becomes object in this invention should have in the outer peripheral part of a bottom part is not restricted to a protruding item | line, and does not necessarily need to extend over the perimeter.
[0021]
The front-rear and top-bottom positional relationship of the box overturning device 12 will be described based on the state of FIG. 1 showing a side view of the ball counting device 10 when placing and removing the ball box.
[0022]
The box body overturning device 12 includes a left and right side plate 12a, a hollow bottom support plate 12c having a front protruding handle 12b on the front (left side in FIG. 1), a left and right pivot shaft 12d, and a rear support 12e. And the claw member 12f.
[0023]
The left and right pivot shafts 12d having lateral pivot axes allow the box overturning device 12 to pivot with respect to the ball counting device 10 at the upper and lower intermediate positions at the rear portion (right portion in FIG. 1) of the left and right side plates 12a. To support.
[0024]
The left right plate 12a is fixed to the left and right ends of the bottom support plate 12c and rises from the bottom support plate 12c. The rear upper part of the left right side plate 12a has a disc shape, and the height of the front side gradually decreases toward the front. As shown in FIG. 1, in the state where the bottom support plate 12c is inclined slightly rearward and downward, the upper edges of the left and right side plates 12a are positioned slightly lower than the upper edges of the ball counting device 10 except for the disc-shaped portion.
[0025]
A rear support 12e protrudes upward over substantially the entire width at the rear end of the bottom support plate 12c. The rear support 12e has a bent portion 12e1 (constituting a rear upper edge support) slightly protruding forward at the upper end. A portion of the rear support 12e below the bent portion 12e1 constitutes a rear side support. It is preferable that the height of the upper end portion of the rear support 12e corresponds to the height of the target ball box 20.
[0026]
The bottom support plate 12c, the rear support 12e, and the left and right side plates 12a rotate integrally around a left and right rotation shaft 12d. The range in which the bottom support plate 12c can be rotated includes a rotation angle shown in FIG. 1 inclined slightly rearward and downward from a horizontal state (a state where the ball box 20 is inclined slightly rearward and standing upright), and a vertical standing state. The rotation angle shown in FIG. 2 is inclined slightly rearward (a state in which the ball box 20 is slightly inclined backward and falls). In such a rotation range, when the ball box 20 is placed on the bottom support plate 12c in the state shown in FIG. 1, the rear side portion of the ball box 20 is in contact with the rear support 12e and the rear side. The downward protruding ridge 20c that is supported from the rear and located at the rear part (right part in FIG. 1) of the ball box 20 can be easily supported from the front side by the claw part 12f1 when the bottom support plate 12c stands. Further, since the bottom support plate 12c does not rotate more than necessary, there is no need for an extra operation, and unexpected dropout of the ball box 20 from the box body overturning device 12 is prevented. The restriction of the rotation range is, for example, by providing a radial protrusion (not shown) on the rotation shaft 12d and limiting the range of movement of the radial protrusion by a stopper (not shown), or This can be done by limiting the range of movement of the bottom support plate 12c with a stopper (not shown).
[0027]
In the hollow portion of the bottom support plate 12c, six claw members 12f are arranged at the same position in the front and rear direction at intervals in the lateral direction, and each claw member 12f is rocked at its front end so that it can swing independently of each other. It is supported by the swing shaft 12g. The claw member 12f has a vertical plate shape that gradually becomes narrower toward the rear and has a claw portion 12f1 projecting upward at the rear end (both sides are substantially orthogonal to the horizontal plane). At positions corresponding to the respective claw portions 12f1 at the rear end portion of the upper surface of the bottom support plate 12c, claw portion intrusion holes 12h having a long rectangular shape in the front-rear direction are provided.
[0028]
Depending on the position of the axis of the oscillating shaft 12g, the position of the center of gravity of the claw member 12f, and the protrusion of the claw portion 12f1, the claw member 12c is clawed when the bottom support plate 12c is inclined slightly rearward and downward from the horizontal state as shown in FIG. The portion 12f1 does not protrude from the claw portion intrusion hole 12h, and the claw portion 12f1 does not protrude from the vertical standing state to a state slightly inclined backward as shown in FIG. It is comprised so that it may protrude from 12h. The ball box 20 is placed on the bottom support plate 12c in the state shown in FIG. 1, and the portion of the upper edge portion 20a protruding rearward in the rear side portion of the ball box 20 is in contact with the rear support 12e. In this case, and when the ball box 20 is removed from the bottom support plate 12c in the state shown in FIG. 1, the claw portion 12f1 is submerged in the bottom support plate 12c, so that the claw portion 12f1 does not interfere with the work.
[0029]
The dimension by which the claw portion 12f1 can project depends on the target box, but is preferably capable of projecting, for example, about 2 to 3 cm. The claw portion 12f1 may be fixed in an upward projecting state. Further, the claw portion 12f1 may be elastically held in a protruding state by using, for example, a spring or the like.
[0030]
A portion of the upper edge portion 20a that is placed on the bottom support plate 12c in a substantially upright state and that protrudes rearward from the rear side portion (right side portion in FIG. 1) of the ball box 20 in a substantially upright state. Is in contact with the rear support 12e, and when the bottom support plate 12c is rotated backward by holding the handle 12b, the upper edge of the rear side portion of the ball box 20 falls as the ball box 20 falls backward. The portion 20a is supported from the rear side by the rear support 12e and the rear upper edge portion 20a (upper right edge portion in FIG. 1) of the ball box 20 is supported from the upper side by the bent portion 12e1, while the ball box 20 is rearward. To move over the bent portion 12e1 of the rear support 12e and drop backward.
[0031]
At that time, as shown in FIG. 2, the claw portion 12f1 protrudes, and the downward protrusion 20c located at the rear portion of the ball box 20 is supported from the front side by the claw portion 12f1, so that the rotation of the ball box 20 to the rear is performed. It is prevented and falling off to the rear is prevented, and the state in which the ball box 20 is tilted slightly backward and falls is maintained.
[0032]
When the position of the claw portion 12f1 coincides with the downward protrusion 20c located on the side of the ball box 20, the claw portion 12f1 can hardly protrude from the claw portion intrusion hole 12h, but the other claw portions 12f1 It protrudes from the partial intrusion hole 12h. The pachinko balls housed in the ball box 20 are discharged backward and thrown into the ball slot 14.
[0033]
In addition, it is desirable that the bent portion 12e1 of the rear side support body does not protrude forward from the rear upper edge portion of the ball box 20 as much as possible so as not to obstruct pachinko ball discharge.
[0034]
If the bottom support plate 12c is returned to the original position shown in FIG. 1 after the pachinko balls are discharged, the ball box 20 also returns to the original upright state, and the claw portion 12f1 is immersed in the bottom support plate 12c. The ball box 20 can be easily removed from the bottom support plate 12c.
[0035]
It should be noted that the dimensions, number, material, shape, relative arrangement, etc. of the component parts in the description of the above embodiments are limited to the scope of the present invention unless otherwise specified. It is not intended to be limiting, but merely an illustrative example.
[0036]
【The invention's effect】
According to the present invention, the box body is placed on the bottom support body in a substantially upright state, and the bottom support body is rotated backward about the rotation axis, thereby preventing the rear dropout. The body can be turned backwards, so that the game medium and the like stored in the box can be discharged to the slot of the game medium counting device. If the box is placed on the bottom support in an almost upright state, the box can be overturned by the rotation of the bottom support, so that a large amount of game media such as pachinko balls and coins for slot machines can be used. Even when the game media is discharged from the housed box to a fixed place such as the insertion port of the game media counting device, unlike the case where the box is directly overturned by the operator, the operation is easy and reliable. Can be done. However, unlike the case where a pachinko ball is allowed to flow down by opening a part of the bottom of the box, no special mechanism is required for the box, which increases the cost of the box, complicates maintenance, or reduces capacity. In addition, the articles that can be discharged from the box are not limited to spheres such as pachinko balls, but can be any shape.
[0037]
When the range in which the bottom support can rotate is between a state in which the supporting box tilts slightly backward and erects and falls, the box supports the box on the bottom support. The rear side part of the body is supported from the rear side by the rear side support body, and the downward projecting portion located at the rear part of the box body can be easily supported from the front side by the claw part. Further, there is no need for an extra turning operation of the bottom support, and unexpected dropout of the box can be prevented.
[0038]
The bottom support is positioned at a rotation angle at which the supporting box is almost upright, and the box is made the bottom support with the rear side of the box supported from the rear side by the rear support. When supporting, and when removing the box body from the bottom support body at the rotation angle position, the claw part does not substantially protrude toward the bottom part of the box body, so the claw part does not interfere with the work. Is easy.
[0039]
If the position of the downward projecting part differs depending on the type and placement of the box, depending on the position of the claw part, it may not project because it matches the position of the downward projecting part, or forward from the downward projecting part located at the rear of the box It may be too far away or displaced rearward and cannot be supported from the front side, or may protrude into a portion where no protrusion exists. However, when a plurality of claw portions that are independently operated to project are provided at different positions in the lateral direction and / or the front-rear direction, a downward projecting portion positioned at the rear of the box body by any of the claw portions is provided. It is possible to support from the front side with high certainty and prevent the box from falling backward.
