DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for conveying and polishing pachinko balls.

[0002]

2. Description of the Related Art A so-called lift-type polishing apparatus is conventionally known as this type of pachinko ball transfer polishing apparatus. This lift type vertical polishing apparatus is disclosed in
As shown in JP-A 1-125365 and Japanese Utility Model Application Laid-Open No. 2-25288, it has a guide member having a gutter groove through which a pachinko ball passes, and a transport belt for transporting the pachinko ball while pressing it against the gutter groove side. There is a belt polishing method.

[0003] That is, pachinko balls are in accordance with the rotation of the endless belt, in the process of being conveyed in trough grooves from the lower inlet side to the upper outlet side, is cleaned by adhering the dirt on the endless belt, The pumped pachinko balls are supplied to each pachinko machine. In this case, the endless belt is washed at an appropriate time, usually every day.

On the other hand, a large number of abrasive beads are put into a vertical conveying path, and the abrasive beads are brought into contact with pachinko balls.
The pachinko balls are subjected to the polishing action, and are finally discharged from the exit as polished pachinko balls, while the polished beads are separated from the pachinko balls and then thrown into the transport path for reuse , and are contaminated for a certain time. The so-called abrasive bead system, which is configured to circulate until the pressure reaches a limit, is also known.

[0005]

However, in this conventional polishing apparatus, it is fundamental to transfer dust, dirt, oil and the like adhering to pachinko balls to an endless lifting belt or polishing beads. When the belt or the polishing beads become heavily soiled after a long operation, the belts or the polishing beads have to be washed and reused or replaced with new ones.

[0006] In the case where abrasive beads are used, a special cleaning device is separately required to remove the dirt.

Therefore, in the above-mentioned belt polishing method,
The dirt transferred to the cloth transport (transport) belt is removed by towels
In the case of wiping or when the dirt becomes severe, it is necessary to remove the conveyor belt from the polishing apparatus and wash it. For this reason, it is necessary for the pachinko parlors to perform cleaning after the end of business hours, which is a great burden.

[0008] On the other hand, in the polishing bead system, a dedicated cleaning device is separately required, which not only increases the cost but also increases the cost.
The beads or their fragments are mixed into the pachinko machine,
It causes trouble.

Therefore, the inventor of the present invention disclosed in Japanese Patent Laid-Open No.
No. 0231 proposes that the belt polishing method is improved, and a number of polishing blocks (constituting the conveyance guide member of the present invention) are provided in the conveyance direction, so that dirt is scraped off by the conveyance direction edge of the polishing block. did.

[0010] According to the present invention, in practice, the transport belt is hardly contaminated, and the contaminants are mainly contaminated on the conveying surface of the polishing block, and more contaminants are eventually removed from the gap between the polishing blocks. It has been confirmed that it shifts to the back side of the block.

Therefore, it has been confirmed that even if the conveyor belt is cleaned, it is only necessary to wipe it off with a towel after a long-term operation, and that a separate cleaning device is unnecessary. Furthermore, for unknown reasons, the outer surface of the polished pachinko ball is much more beautiful than any other method and can remove oil from dirt.

In the embodiment of the above-mentioned prior invention, a parallelogram is seen in a vertical section (a horizontal section in the case of the polishing block itself) which vertically cuts through the conveyor belt of the polishing block. in this case,
As will be described in detail later, if the conveying force applied to the pachinko balls becomes abnormal due to some external factor, the posture of the polishing block is raised, and as a result, the pachinko balls are densely moved in the moving direction of the pachinko balls, and the guide path is A gap is generated inside the inside, and a subsequent pachinko ball is deposited therein, and a situation occurs in which the conveyance cannot be performed thereafter.

Accordingly, a main object of the present invention is to provide a pachinko ball having an excellent polishing effect and to eliminate or reduce the frequency of cleaning of the conveyor belt to enable a substantially continuous operation. In addition, the position of the polishing block (guide member) is stabilized while maintaining the advantage of the above, and as a result, guided continuous operation is performed.

[0014]

Means for Solving the Problems The present inventor obtained the following knowledge in the course of studying a drastic solution in order to solve the above-mentioned problems of the conventional polishing apparatus.

That is, in the conventional polishing apparatus, since both sides of the pachinko ball path are continuous over the entire lifting distance, dirt and dust do not escape and adhere to at least one of the guide path and the transport belt. things der
You. Therefore, if a path is formed in the guideway that constitutes the wall to allow dust and moisture to escape to the opposite side of the pachinko ball path,
We noticed that the dust of the pachinko balls that were sequentially introduced was not accumulated.

For this purpose, for example, if a suitable hole is formed in the guide path, dust and moisture escape from the hole. However, in addition to dust that easily falls off the pachinko balls, moisture that retains them, tobacco tar, sweat, and fat on the skin of the hands are firmly attached to the pachinko balls, making it extremely difficult to remove them. It is. Regarding moisture, it has been empirically found that, particularly during the rainy season, poor transport of pachinko balls occurs.

[0017] Therefore, not only to remove dust and moisture, without using an abrasive medium such as polishing beads, forcibly scraping method suitable der the dirt guideway itself
I arrived at the idea.

Under this concept, a prior invention has been proposed.
Further, in the present invention, in the process of compressing the guide member by interposing the pachinko balls and restoring the elastic force by the elastic member, the posture of the guide member is prevented from being deformed, and stable compression and restoration are performed.

That is, according to the present invention, a guide path is formed by providing a plurality of conveying guide members adjacent to the pachinko ball moving direction in a groove along the longitudinal direction of the housing member, and pachinko balls are interposed in the guide path. A conveyance belt is provided opposite to the guide path at intervals to be provided, and between the guide path and the conveyance belt, each of the guide members is elastically pressed from the rear side, and the pachinko balls are pinched resiliently. It is configured to convey while rolling the pachinko balls by moving the conveyance belt,
At least one of the two edges in the moving direction of the rolling surface of the pachinko ball of the guide member has a rectangular shape when viewed in a vertical cross section that vertically cuts through the conveyor belt. A limit is set, and at least a part of the adjacent surface of the guide member is a surface substantially orthogonal to the longitudinal section, and the orthogonal surfaces are adjacent to and in contact with each other. is there.

Here, it is desirable that the downstream edge in the moving direction of the rolling surface of the pachinko ball is formed at an acute angle.

Further, a mode is proposed in which a communication concave groove is formed on the upstream surface of the guide member to connect the rolling surface of the pachinko ball with the groove bottom side of the storage member.

Furthermore, the discharge groove along the direction of movement of pachinko balls is formed on a rear surface of the guide member, and discharge of the guide member
It is preferable that the concave and convex grooves are arranged along one row.

Further, the pachinko ball moving portion may be formed by gutter grooves extending in the moving direction.

[0024]

According to the present invention, a plurality of guide members for conveyance are provided adjacent to each other in the moving direction of the pachinko balls in a groove along the longitudinal direction of the housing member to form a guide path, and the pachinko balls are interposed in the guide paths. A transport belt is provided facing the guide path at intervals, and between the guide path and the transport belt,
Each of the guide members is resiliently pressed from the back side, and the pachinko balls are conveyed while rolling while rolling the pachinko balls by the movement of the conveyance belt while pinching the pachinko balls resiliently.

Therefore, when the pachinko ball rides on the corresponding guide member during the movement of the pachinko ball, the guide member is pressed in reverse and moves toward the groove bottom of the storage member. Eventually, when the pachinko ball moves to the next guide member, the pressing force is released, the pachinko ball moves in the opposite direction, and is restored to the elastic pressure limit by the stopper. Such compression and decompression are repeated during the movement of the pachinko ball.

As a result, in the process of compressing and restoring the guide members, a step is generated between adjacent guide members. At this time, since at least one of the two edges in the moving direction of the rolling surface of the pachinko ball of the guide member is square when viewed in a vertical cross section that vertically cuts through the conveyor belt, the pachinko ball has the step difference. When straddling the pachinko ball, the pachinko ball being rotated and conveyed is rubbed at the square edge, so that the dirt attached to the pachinko ball is removed.

The removed dirt is discharged from the gap between the guide members to the back side of the guide member row.

On the other hand, in the above-mentioned prior invention, since the guide member is a parallelogram, there is a problem that when the guide member stands up, it is impossible to carry out the conveyance. .

However, in the present invention, at least a part of the adjacent surface of the guide member is a surface substantially orthogonal to the longitudinal section, and the orthogonal surfaces are adjacent to and contact each other. Even if an external force in the transport direction of the pachinko balls by the transport belt acts on the guide member, each guide member does not move in the transport direction, and as a result, the posture of each guide member does not collapse. Therefore, the pachinko balls do not become clogged in the transport guide path.

By the way, dirt is discharged to the back side of the guide member row from a small interval between the guide members, but if the operation is performed for a long time, dirt accumulates in the gap, and the dirt is rubbed. As a result, it becomes a factor that hinders the compression / restoring action of the guide member.

Therefore, it is preferable to form a communication groove on the upstream surface of the guide member, which connects the rolling surface of the pachinko ball to the groove bottom side of the housing member. Dirt, sequentially
The storage member is discharged to the bottom of the groove along the communication concave groove .

Further, if a discharge groove is formed on the back surface of the guide member along the moving direction of the pachinko ball, and if the discharge grooves of each guide member are arranged in a row, the discharge member shifts to the back side of the guide member. The dirt flows down along the discharge groove row.

Although the pachinko ball moving portion of the guide member can be a flat surface, the pachinko ball can be smoothly moved in the transport direction, and the edge can be hit by an arc when hitting the edge. There are advantages to increase.

Although there are various types of dirt on pachinko balls, according to the present invention, moisture, tarnish of cigarettes, sweat, fat on the skin of the hands, and dirt formed by integrating these with dust and the like are determined. Can be reliably removed.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 and FIG. 2 show the entirety of a lift-type polishing apparatus of the present invention, for example, provided at the center of an island of a pachinko machine, and a transport guide member 2 provided on a vertical storage member 1. , 2,..., A conveyance belt 3 made of endless cloth, rubber, etc.
Are arranged. The conveyor belt 3 includes upper and lower drums 4,
5, the lower drum 5 is configured to rotate the output shaft of a drive motor 6 via a drive belt 7.

The dirt pachinko balls B0 are introduced into the entrance 8 and guided between the guide member 2 and the conveyor belt 3, and are pressed upward by the pressing force of the pachinko balls by the relative resilient pressure and the conveying force of the conveyor belt. It is conveyed, and in this process, it is polished as described later, and is discharged from the outlet 9 as polished pachinko balls B1. Reference numeral 1A denotes a main body frame as a structural material.
Is disassembled to facilitate disassembly or cleaning when necessary. When the storage member 1 is removed, the transport belt 3 is exposed.

In the present invention, the guide member 2 is formed of a material exhibiting abrasiveness as the pachinko ball moves (slids or rolls). For example, a hard or soft plastic mixed with a pigment or abrasive powder, a roughened surface, or the same material as conventional abrasive beads can be used. Further, it may be made of ceramics or the like. As more specific examples of these materials, nylon 66 (trade name), polyacetal resin, high-density polyethylene, or 10 to 50%
And the like can be mentioned.

The guide member 2 may be formed by forming an appropriate number, for example, 5 or 12 gutter grooves 20 having a semicircular cross section in the width direction. The length of the guide member 2 in the moving direction of the pachinko balls is preferably about 7 to 300 mm, particularly about 10 to 50 mm, in order to enhance the polishing action per transfer.

A detailed example of the guide member 2 is shown in FIGS. Here, in the following description, the transport belt 3
Is referred to as a “longitudinal section” (that is, for example, as viewed in the direction of arrow 4-4 in FIG. 3), and a plane orthogonal to the “longitudinal section”
That is, a plane crossing the conveyor belt 3 is referred to as an “orthogonal plane”.

That is, in the embodiment, as shown in FIG. 3, the guide member 2 has three feet 21, 21 and 21 at the lower part of the main body 20, and the The fitting holes 22 into which the springs 30 as means are inserted are respectively formed.

The front and rear surfaces in the alignment direction of the main body portion 20 and the foot portion 21 form an orthogonal surface as clearly shown in FIG. Therefore, when the guide members 20, 20,... Are adjacent to each other, they are aligned with each other on the front and rear orthogonal surfaces 23A, 23B as shown in FIG.

On the upper surface of the main body 20, a plurality of pachinko machines, for example, a semi- circle of 11.2 mm, slightly larger than the diameter of the pachinko balls (11 mm) are provided in the width direction of the machine (in the direction perpendicular to the transport direction). Gutter grooves 24, 24... Are formed along the transport direction that constitute the moving (rolling) portion of the ball.

The front and rear surfaces of the upper part of the main body 20 in the transport direction are inclined surfaces. In the embodiment, the inclination angle α of the front inclined surface (upstream surface) 25 in the transport direction is 35 degrees, and the inclination angle β of the rear inclined surface (downstream surface) 26 is 25 degrees.
As shown in FIG. 9, when the guide member 2 is compressed, the boundary position between the front inclined surface 25 and the front orthogonal surface 23A is set to the rear inclined surface so that the adjacent inclined surfaces of the guide members 2 do not contact each other. 26 and the rear orthogonal plane 23B. 27 is a connecting surface.

Further, the front inclined surface 25 and the front orthogonal surface 23
3A, a communication groove 28 extending downward from FIG. 3 from the bottom of the gutter groove 24 is formed.
Corresponding to the formation position of the discharge groove 2 on the back surface of the main body 20.
9 are formed. Since the guide members 2, 2,... Have the same shape, when they are aligned, the discharge groove 29 is formed continuously in the vertical direction.

On the other hand, the downstream end of the gutter groove 24 extends to the rear inclined surface 26, so that the downstream edge 24A has an acute angle. In contrast, the upstream end of the gutter groove 24 is
Since the connecting portion with the front inclined surface 25 is chamfered, no edge is formed. This is because, as will be described later, when the pachinko balls enter the gutter groove 24, the pachinko balls smoothly enter, and when they exit, the dirt on the pachinko balls is scraped off and polished at the edge 24A. is there.

The guide members 2, 2,... Are held via a resilient spring 30 in a storage member 1 having a substantially lip groove-shaped cross section, as shown in FIG. One end of the repulsion spring 30 is inserted into the fitting hole 22 on the back of the guide member 2.
The other end is in contact with the bottom surface of the storage member 1 and presses the guide member 2 toward the conveyor belt 3. Guide member 2
Of the storage member 1 abuts against the stopper pieces 1a, 1a constituting the stopper of the present invention to prevent the storage member 1 from coming off and to limit the elasticity when the elasticity is restored.
In FIG. 7, reference numeral 40 denotes a guide roller for the transport belt.

Under such a configuration, as described below, the transfer polishing of the pachinko balls is performed. That is, the pachinko ball B0
The pachinko ball B0 and the conveyor belt 3 are pressed against each other in order to surely lift up. In this embodiment, the guide member 2 is pressed against the conveyor belt 3 by a repulsion spring 30 provided between the guide member 2 and the storage member 1. Between the gutter 24 and the gutter groove 24 via the pachinko balls B0 with a short separation interval, so that a strong pressing force is applied to the pachinko balls B.
Acts on zero.

In the present invention, in the process of rolling and transporting the pachinko balls B0 by the transport belt 3, the dirt D is polished or removed at the edge 24A of the inclined surface 26 in the gutter groove 24.

This process will be described with reference to FIGS.

That is, the pachinko ball B0 rolls and moves from the left side in FIG. With this movement, for example, FIG.
As described above, when reaching the second guide member 2, the pachinko ball B0 is pressed by the storage member 1 side by the tensioned conveyor belt 3, moves to the rear side, and pushes down the second guide member 2. Become. When the rolling and transport of the pachinko balls progresses and the center thereof is biased toward the third guide member 2, the second guide member 2
Is gradually restored to the conveyor belt 3 side. Therefore, a step is formed between the second guide member 2 and the third guide member 2. In the process of this step, pachinko ball B
Since 0 rolls, d of the second guide member 2 of the inclined surface 26
The Tsu di 24A, resulting an effect of the surface of the relatively pachinko balls B0 is cut, as a result, dirt component D is that edge
Removed by 24A . The operation of scraping off the dirt D is performed each time the guide member 2, 2. As a result, the pachinko balls B1 are discharged from the outlet 9 as ground pachinko balls B1.

The dirt content D, as shown by the arrow D in FIG. 9,
Through the communication groove 28, it is dropped downward while being guided by the discharge groove 29. The depth of the communication concave groove 28 is preferably 0.5 to 7 mm. If the length is short, the effect of discharging the dirt D is small and clogging occurs. Conversely, if the length is large, it is difficult to form a step in the state shown in FIG. This is because the effect is reduced.

In the above embodiment, the pachinko balls are conveyed through the gutter grooves 20, but even if the rolling surface of the pachinko balls is a mere flat surface without gutter grooves, the effect of scraping off the dirt D is similarly exerted. The angle β of the inclined surface 26 is preferably 10 to 45 degrees. However, it has been confirmed by an experiment that there is an effect of removing dirt up to minus 30 degrees. Angle β
Is small or in the minus direction, the shaving effect is not sufficient. Conversely, if it exceeds 45 degrees, there is a problem in terms of edge durability. It is desirable that the edge of the rear inclined surface 26 be as sharp as possible from the viewpoint of the shaving effect. However, in some cases, chamfering within a range of about 1 mmR can be performed.

On the other hand, in the above example, the edge is formed on the downstream side, but may be formed on both the upstream side and the downstream side. In this case, in the process of shifting from the front guide member to the rear guide member, dirt is scraped off by the upstream edge. This aspect can be easily guessed without being shown.

In the present invention, conventional polishing beads are not basically used, but may be used if necessary. On the other hand, the polishing apparatus of the present invention can be applied not only to the lift type, but also to a mode in which polishing is performed when a slightly inclined pachinko ball is transported as a supply gutter. In addition, the polishing apparatus of the present invention can be installed in an appropriate position at an appropriate position in a pachinko parlor.

On the other hand, the dirt can be discharged to the back side by forming a discharge hole that penetrates through the main body 20 and passes from the middle of the gutter groove 24 to the back.

[0056]

As described above, according to the present invention, the polishing effect of the pachinko balls is remarkably excellent, and further, the cleaning of the conveyor belt is eliminated or the frequency of the cleaning is significantly reduced, thereby enabling a substantially continuous operation. it can.
