DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko ball feeding apparatus for feeding a pachinko ball used in a pachinko game hall from a low place to a high place. It is about. The pachinko ball lifting device partially configures a pachinko ball circulation system.

[0002]

2. Description of the Related Art As a conventional pachinko lifting apparatus, there is one described in Japanese Patent Publication No. Hei 3-19792 (hereinafter referred to as "conventional lifting apparatus"). A conventional lifting device will be described with reference to FIG. FIG. 7: is the figure which looked at the cross section of the horizontal direction of a lifting belt and a guide member from the top. The conventional lifting device generally includes a lifting belt 100 extending in the lifting direction of the pachinko machine, that is, a vertical direction (from the back side of the paper to the front side), and a guide member 104 extending in the vertical direction in parallel with the lifting belt 100. ing. An opposing surface 106 for pinching the pachinko balls with a friction contact surface 102 formed on one side surface of the lifting belt 100 is provided on the guide member 104 to guide the pinched balls in the lifting direction. , A plurality of unloading guideways 108,. .
Are provided on the facing surface 106, and a polishing sheet 110 for polishing pachinko balls is further provided. The polishing sheet 110 is provided between the pinched pachinko ball and the guide member 10.
4 between the opposed surfaces 106 under tension.
Due to the pressure received from this pachinko ball, the lifting guideway 10
8,. . It is designed to be flexibly deformed inside. Friction contact surface 10 associated with rotational drive of lifting belt 100
2, the pachinko balls that have been held are brought into rotational contact with the polishing sheet 110 to form a polishing surface (described later) while the lifting guide paths 108,. . It is configured to be transported along. As shown in FIG. 8, when the lifting belt 100 rotates from the back side to the front side of the paper, the frictional action of the frictional contact surface 102 acts to rotate the pachinko ball P in the direction of arrow A. With this rotation, the pachinko ball P is turned into the polishing sheet 11.
It is polished by rotating contact with 0 (contact while rotating).

[0003]

However, the conventional lifting device has room for improvement in the following points. The description will be continued with reference to FIG. The contact between the frictional contact surface 102 and the pachinko ball P is a point contact at the contact point 101, and the direction of rotation applied to the pachinko ball P by this contact is other than the direction indicated by the arrow A. Therefore, the surface of the pachinko ball P polished by the rotational contact with the polishing sheet is only the portion indicated by Pc, and the dirt remains on the side portions Pd and Pd indicated by oblique lines. In this,
This has not completely fulfilled the purpose of polishing dirty pachinko balls, and moving such dirty pachinko balls through the circulation system can cause dirt to clog and cause unexpected failures. Maybe. In addition, a player who got a dirty pachinko ball stained his hands and clothes,
This may be the source of complaints about the amusement arcade. The problem to be solved by the present invention is to make polishing of pachinko balls during freight as efficient as possible.

[0004]

Means for Solving the Problems The inventor of the present invention, which has conducted intensive studies to solve the above-mentioned problems, has found that the cause of the remaining dirt, that is, the portion that is not polished, is that the rotational direction A of the pachinko ball is constant. First, we paid attention to
Since the rotation of the pachinko balls is given by the rotation of the lifting belt, if the rotation direction of the lifting belt can be changed, it is natural that the rotation direction A of the pachinko balls can also be changed. . However, changing the direction of rotation of the lifting belt cannot be realized at all because it is technically possible but requires complicated driving means. Therefore, I came up with the idea that the lifting belt applied another frictional force or another frictional force or a mechanical impact to the pachinko balls being lifted by this lifting belt,
Thereby, the pachinko ball is rotated in a direction different from the conventional rotation direction A. By rotating in different directions, first, the polished surface P
If c is polished and then its rotation direction is changed, Pd,
This is because the Pd portion can also be brought into rotational contact with the polishing sheet 110. The present invention has been made from such a viewpoint. The configuration will be described again in a section.

The structure of the invention described in claim 1 is a pachinko ball frying device according to the invention described in claim 1 (hereinafter referred to as the "pachinko ball frying device of claim 1"). A tensioned lifting belt, a driving means for rotating and driving the lifting belt in the lifting direction, a first friction contact surface formed on one side surface (a surface that comes into contact with the pachinko balls) of the lifting belt, A guide member having an opposing surface for pinching (holding) the pachinko ball between the first frictional contact surface and a lifting guide path formed on the opposing surface for guiding the pachinko ball in the lifting direction And a polishing sheet interposed in tension between the pachinko balls and the opposing surface, and flexibly deformed in the lifting guide path by the pressure received from the pachinko balls, and a rotational driving of the lifting belt. Accompany the first
The frictional action of the frictional contact surface of the pinching pin is configured to be rotatably contacted with the polishing sheet to form a polished surface and to be lifted along the lifting guide path in the prior art described above. It has the same configuration as the lifting device.

The most important feature of this pachinko ball fryer is
In order to form the width of the lifting passage so that only one pachinko ball can pass through it, and to move the pachinko ball to be lifted in the width direction (without falling down) (in a direction different from the lifting direction) while holding the pachinko ball to be lifted A relief groove (space) is provided in this lifting guide path, and a position where one side surface of the lifting belt can contact a pachinko ball having a second friction contact surface different from the first friction contact surface interposed therebetween. The pachinko ball that has come into contact with the second frictional contact surface is reciprocated in the escape groove to change the direction of the polished surface of the pachinko ball. The “first friction contact surface” and the “second friction contact surface” mean all forms having the following effects, and as such, are provided on one side surface of the lifting belt. Any surface that can come into contact with the pachinko balls of the formed grooves, protrusions, protrusions, and the like can be given as examples. Neither contact surface need necessarily be planar. Combination of planes and curved surfaces,
A surface having irregularities on the surface to increase the friction coefficient also corresponds to the first and second friction contact surfaces.

According to the first aspect of the present invention, the pachinko ball lifting device according to the first aspect has a first friction contact surface of a lifting belt rotationally driven by a driving means, and a guide member having a polishing sheet interposed therebetween. The pachinko ball sandwiched between the opposing surfaces is lifted along the lifting guide path while rotating. The polishing sheet forms the polished surface by polishing the surface of the pachinko ball that has been brought into rotational contact. At this time, the tension applied to the polishing sheet repels the pressure received from the pachinko balls, but is deformed according to the shape of the lifting guide path and the pachinko balls due to its flexible nature. This repulsive force works to press the abrasive sheet against the surface of the pachinko ball,
When the pachinko ball passes and is no longer pressed, the polishing sheet is returned to its original state. Here, the second
The frictional contact surface of (1) applies a frictional force (mechanical impact) to the pachinko ball. This frictional force forms a resultant force together with the frictional force received from the first frictional contact surface, and the pachinko ball receiving this resultant force rotates in a direction different from the rotation direction of the first frictional contact surface while retaining the pachinko balls in the clearance groove. To move. The moved pachinko ball is rebounded by the collision of the inner wall of the lifting guideway or the like and returns to the original position. This is repeated, and the direction of the polished surface of the pachinko ball changes each time the ball reciprocates, and eventually the entire surface of the pachinko ball is polished.

The structure of the invention described in claim 2 The pachinko ball frying apparatus according to the invention described in claim 2 (hereinafter referred to as the “pachinko ball frying apparatus of claim 2”) The configuration of the device is limited,
A V-shaped groove having a V-shaped cross section extending in the longitudinal direction is provided on one side surface of the lifting belt, and one inclined surface of the V-shaped groove acts as a first frictional contact surface. The other inclined surface is formed so as to fulfill the function of the second friction contact surface, and a pachinko ball is sandwiched between the opposed surface and one inclined surface of the V-shaped groove extending in the length direction. A possible inclined surface is formed, and a relief groove is provided at a position facing the other inclined surface of the V-shaped groove.
In addition, the “V-shape” in the present specification means a shape including one and the other inclined surfaces, such as the V-shape of the alphabet. A shape in which an upward katakana U-shape is deformed to have an inclined surface or the like also corresponds to this shape. It is needless to say that a shape which is not symmetrical to the left and right also corresponds to this shape.

According to the second aspect of the present invention, the operation of the pachinko ball lifting apparatus according to the second aspect is that the pachinko ball lifting apparatus is operated while polishing the pachinko ball. And basically the same. That is, the former exerts a frictional force on the pachinko ball sandwiched between one inclined surface of the V-shaped groove and the opposing inclined surface, and the surface of the pachinko ball is polished by rotating contact with a polishing sheet deformed according to the latter. I do. The pachinko ball changes the direction of the polished surface while reciprocating within the clearance groove at the opposing position (the position facing the surface) due to the frictional force received from the other inclined surface of the V-shaped groove.

The structure of the invention described in claim 3 The pachinko ball frying apparatus according to the invention described in claim 3 (hereinafter referred to as the “pachinko ball frying apparatus of claim 3”) is a pachinko ball of claim 2. The configuration of the lifting device is limited, and the angle formed between one inclined surface of the V-shaped groove and the horizontal plane is the angle formed between the other inclined surface of the V-shaped groove and the horizontal plane. Is different from the above. That is, the angle formed between one inclined surface and the horizontal plane was formed larger (smaller) than the angle formed by the other inclined surface, instead of being symmetrical.

According to the third aspect of the present invention, the operation of the pachinko ball frying device of the third aspect is in addition to the operation of the pachinko ball frying device of the second aspect, and a frictional force applied to the pachinko ball from one inclined surface. Is different from the direction of the frictional force applied from the other inclined surface, the balance of the pinched pachinko balls is more easily lost than in the case where both directions are equal, and thereby the reciprocating motion in the escape groove is promoted. The more the reciprocating movement becomes active, the more frequently the direction of the polished surface changes.

The structure of the invention described in claim 4 The pachinko ball frying apparatus according to the invention described in claim 4 (hereinafter referred to as “pachinko ball frying apparatus of claim 4”) is a pachinko ball of claim 3. A configuration in which the structure of the lifting device is limited, wherein the first frictional contact surface, the opposed slope, and the second frictional contact surface are provided.

Specifically, when the first frictional contact surface is located on the left side at a certain position of the lifting belt, After that, the first frictional contact surface is arranged on the right side, and the second frictional contact surface which has been on the right side is arranged on the left side. To return to the original position.

According to the fourth aspect of the present invention, the operation of the pachinko ball lifting device according to the fourth aspect is the same as that of the third aspect. Is replaced by the other, so that the direction of the polished surface changes each time it is replaced.

FIG. 1 is a partially cutaway schematic view showing the structure of the pachinko fryer, and FIGS. 2 (1) and (2) show the II section of FIG. 1 viewed from the direction of the arrow. It is. FIG.
FIG. 4 is a schematic view showing a process of forming a polished surface on the surface of a pachinko ball. 4 and 5 are views showing a modification of the present embodiment. FIG. 6 is a schematic diagram showing an application example of the present embodiment and the modification.

[0017] Number 1 in the overall structure Figure 1 shows a pachinko pumped device for pumped to the storage tank 52 installed pachinko balls upwards, each member of the pachinko pumped device 1, an understanding Exaggerated to help. Pachinko lifting equipment 1
Has a guide member 3 extending in the lifting direction (longitudinal direction), a polishing sheet 4 for polishing pachinko balls to be lifted, and an endless lifting belt 5 stretched in the lifting direction. The guide member 3 is supported by the guide support plate 6 and the lifting belt 5 is supported by the belt support plate 7.
It is configured so that it can be opened and closed by means of 4.
The lifting belt 5 is stretched between a driving motor (driving means) 8 at the lower end and a driven pulley 9 at the upper end, and is driven to rotate in the direction shown in FIG. When maintenance replacement or cleaning of members is required, the support plate 7 is opened.

[0018] Based on the pumped belt 2 (1) and (2) it will be described pumped belt. The lifting belt 5 in the present embodiment is a single rubber belt having a width capable of lifting only one pachinko ball P. In the present embodiment, a plurality of lifting belts 5. . . It has. Here, one single belt will be described for convenience of description. As shown in FIG. 2, the lifting belt 5 includes a V-shaped groove 11 having a V-shaped cross section. The V-shaped groove 11 has a first frictional contact surface 12 and a second contact surface 13 that come into contact with the pachinko ball P, and the angle Θ1 formed between the former and the horizontal plane is different from that between the latter and the horizontal plane. It is formed to be larger than the forming angle Θ2 (claims 1 to 3). This disturbs the balance of the pachinko balls P shown in FIG. 2A and biases the pachinko balls P toward the second inclined surface 13, thereby minimizing the effect of the frictional force that the pachinko balls P receive from the second inclined surface 13. I tried to make it bigger. According to the experiment of the inventor, the angle Θ1 is set to about 25 degrees and the angle Θ
Good results were obtained when 2 was about 20 degrees. These angles can be appropriately changed according to the material of the lifting belt 5 and the processing state of both friction contact surfaces, and if necessary, the angles Θ1 and Θ2 can be made equal. 1 and 2). The reason why the V-shaped groove 11 is formed in the lifting belt 5 in the present embodiment is that the structure is relatively simple and the processing of the lifting belt is easy. Instead of a plurality of single belts, a plurality of V-shaped grooves may be formed in a flat belt.

Guide Member The guide member 3 will be described with reference to FIGS. 2A and 2B. The guide member 3 is made of an elastic material to flexibly respond to the movement of the pachinko ball P, securely pinch it with the first frictional contact surface, and apply a frictional force.
For example? ? ? ? ? ? It is preferable to constitute by. Opposite surface 32 of guide member 3 facing lifting belt 5
Has a lifting guideway 34 having a width through which only one pachinko ball P can pass, over its entire length. The inner wall of the lifting guide path 33 is the first friction contact surface 1 of the lifting belt 5.
2 and a clearance groove 35 for allowing the pachinko ball P to move in the width direction. The opposing inclined surface 34 sandwiches the pachinko ball P with the first frictional contact surface 12, and is polished and polished by the polishing sheet 4 interposed between the pachinko ball P and the opposing inclined surface 34. It is configured to form a polished surface on the surface. Therefore, the distance between the opposed inclined surface 34 and the first frictional contact surface 12 is determined by considering the thickness and elasticity of the polishing sheet 4 as well as the elasticity of these two members and the guide member 3, and a necessary and sufficient clamping force. Is determined to be given to the pachinko ball P.
Pachinko balls P to be lifted if the distance is too long and the clamping force is weak
However, if the distance is too short, the clamping force is too strong, and the lifting efficiency is deteriorated.

Abrasive Sheet The abrasive sheet 4 in the present embodiment uses a durable canvas, and is fixed in a state where tension is applied by pulling the upper end and lower end thereof, and between the guide member 3 and the pachinko ball P. It is interposed. This tension may be generated not only by the fixing method described above, but also by the stretching force of the polishing sheet 4 itself, or may be generated by combining them. The polishing sheet 4 may be made of any material that is not easily worn or broken when the surface thereof is polished by contacting the rotating pachinko ball P. As such a material, for example, Other than canvas, such as cloth, paper, nonwoven fabric, and fiber sheet.

The clearance groove 35 formed in the clearance groove lifting guide path 33 is for permitting the movement of the pachinko ball P in the width direction as described above. The shape is not limited. The clearance groove 35 is formed at a position facing the second frictional contact surface 13 and, as described later, is formed on the second frictional contact surface 13.
The pachinko ball P flipped by is inserted. In the present embodiment, the inner wall 36 of the escape groove 35 is formed in a shape approximate to the spherical surface of the pachinko ball P, and the contact area with the surface of the polishing sheet 4 when pressed by the pachinko ball P is made as large as possible. The polishing efficiency is improved.

Operation of this embodiment The operation of this embodiment will be described with reference to FIGS. Arrow a indicates the rotation direction of the pachinko ball. Arrow b represents the resultant force of the clamping force and the frictional force of the second frictional contact surface 12, arrow c represents the clamping force of the opposing inclined surface 14, and arrow d represents the frictional force of the second frictional contact surface. It is a representation. The arrow e indicates the movement direction of the pachinko ball P by the action of the second frictional contact surface 13 in a simulated manner. The force actually acting on the pachinko ball P is more complicated than that indicated by each arrow, but such notation is used to simplify the description.

It is lifted along the lift guide path 33. The lifting direction in FIG. 2 is from the back side of the paper to the front side. As shown in FIG. 3A, the polishing sheet 4 first forms the polished surface P1 by polishing the surface of the pachinko ball P that has come into rotational contact. Next, the polishing sheet 4 is as shown in FIG.
As shown in FIG. 3, the first frictional contact surface 12 and the opposed inclined surface 34

And the action of the relief groove 35 (the inner wall 36). FIG.
(1) shows the pachinko ball P under the action of the second frictional contact surface 13, and FIG. 2 (2) shows the pachinko ball P moved into the relief groove 36. Further, the pachinko ball P that has reciprocated in the direction of arrow e has a polished surface P3 shown in FIG. Thereafter, the pachinko ball P reciprocating in the direction of arrow e is
As shown in (4), a polished surface P4 is formed on the surface. As a result of this series of actions, the area of the portion Pd to which dirt is attached gradually decreases, and the front surface of the pachinko ball P is eventually covered with the polished surface and becomes clean.

Modified Example A modified example of the present embodiment will be described with reference to FIGS. FIG. 4 shows a pair of protrusions (projected paths) 4 extending in the longitudinal direction of the upper surface of the flat belt 40 instead of the V-shaped grooves 11 formed in the present embodiment.
2, 46 and a first frictional contact surface 44
And a second friction contact surface 46 is formed on the projection 46. On the other hand, FIG.
Instead of 4, 46, projecting 5

And the second friction contact surface 13 (46, 56) and the relief groove 35.
Was changed at predetermined intervals in the lifting direction to change the direction of the polished surface. With this configuration, the frictional force that the pachinko ball P receives from one side until now is received from the other side by replacement, so that the direction of the polished surface is changed every time replacement is performed. The surface of the pachinko ball can be efficiently polished. Note that, here, the “predetermined interval” is set to increase the polishing efficiency.
It is preferable that the interval is at least longer than the outer circumference of the pachinko ball P. In the present embodiment, as shown in FIG. 6, the intervals are periodically changed.
