[Patent Document 1]
Japanese Patent Laid-Open No. 11-276709 (see paragraph 0009, FIG. 7)
[0004]
[Problems to be solved by the invention]
As described above, the guide member of the conventional apparatus is always exposed to the collision and rubbing of the pachinko balls during operation, but the most intense part is the lower end portion. This is because the lower end portion is a portion that receives a pachinko ball that jumps in vigorously, and is therefore most susceptible to an impact by the pachinko ball. The lower end exposed to collision and rubbing can be worn and sometimes even damaged. When severely worn or damaged, the guide member can no longer be used and the entire guide member must be replaced. It is very uneconomical to have to replace the entire guide member, even though parts other than the worn or damaged lower end can still be used, and the amount of industrial waste is increased unnecessarily. This is not preferable. The problem to be solved by the present invention is to provide a pachinko ball polishing apparatus provided with a guide member that does not require replacement of the entire guide member in such a case even if wear or breakage is unlikely to occur. There is.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the inventor comprises a guide member composed of a part related to wear or breakage and the other part, and only the former can be replaced, and the latter can be used without replacement. I was able to do it. The details will be explained anew in the section. It should be noted that the definitions of terms used in the description of the invention in any claim shall be applied to the inventions in other claims as far as possible in nature.
[0006]
(Characteristics of the invention of claim 1)
A pachinko ball polishing apparatus according to the invention of claim 1 (hereinafter referred to as “the polishing apparatus of claim 1” as appropriate) includes a transport tower, and a transport belt having a transport surface that can come into contact with the pachinko balls in the transport tower. A guide member having a guide surface opposed to the conveying surface, a guide groove formed on the guide surface side of the guide member, and a polishing cloth mounted on the guide surface, and the polishing cloth in the guide groove Is a device for conveying and polishing the pachinko balls received via the rotation of the conveying belt. The guide member includes a guide member main body, a lower member positioned at a lower portion of the guide member main body, and a lower attachment / detachment structure provided between the guide member main body and the lower member.
[0007]
According to the polishing apparatus of the first aspect, the pachinko ball sandwiched between the conveyance belt and the guide member via the polishing cloth is conveyed in a predetermined direction by the rotation of the conveyance belt in the conveyance tower. The guide member, particularly the lower member, is exposed to the collision and rubbing of the pachinko balls through the polishing cloth, even though the polishing cloth is interposed. Therefore, the lower member may be worn or sometimes damaged. The worn or damaged lower member is removed from the guide member main body by releasing the attachment action of the lower detachable structure, and another new lower member is attached by driving the attachment action instead. The guide member main body remains as it is, but the guide member can be continuously used by replacing the lower member. Since only the worn or broken lower member is discarded, it is very economical and the amount of waste is much smaller than when the entire guide member has to be discarded. Moreover, although it is rare, the guide member main body may be worn or damaged, and only the lower member may continue to be used. In this case, only the guide member main body can be replaced and the entire guide member can be used continuously. It is economical in that the lower member can be used continuously, and is preferable for waste reduction.
[0008]
(Characteristics of the invention described in claim 2)
A pachinko ball polishing apparatus according to a second aspect of the present invention (hereinafter referred to as “the polishing apparatus according to the second aspect” as appropriate) is the polishing apparatus according to the first aspect, wherein the lower detachment structure is a longitudinal direction of the guide member. And a concave / convex fitting structure that can be inserted / removed, and a retaining structure for releasably preventing the concave / convex fitting structure from coming off. The concave-convex fitting structure refers to a structure in which when either the guide member main body or the lower member has a concave portion, the other has a convex portion that can be fitted to the concave portion. When the former has a concave portion, the latter has a convex portion, and when the former has a convex portion, the latter has a concave portion.
[0009]
According to the polishing apparatus of the second aspect, in addition to the effect of the polishing apparatus of the first aspect, the lower member with respect to the guide member can be attached and detached by the operation of the concave-convex fitting structure. The insertion / removal operation is a relatively simple operation among the attachment / detachment operations, and this simple operation can fulfill the purpose of attachment / detachment, which is very convenient. The retaining structure effectively prevents the lower member from coming off. When replacing the lower member, the retaining structure of the retaining structure is released.
[0010]
(Characteristics of Claim 3)
A pachinko ball polishing apparatus according to a third aspect of the present invention is the pachinko ball polishing apparatus according to the second aspect, wherein the concave-convex fitting structure has at least one through-passage that penetrates the guide member body in the longitudinal direction. Is included. Although there is no restriction | limiting in the cross-sectional shape of a penetration path, A rectangle and circular are common. It is sufficient that at least one muscle penetrates the through path, and a plurality of muscles may be used.
[0011]
According to the pachinko ball polishing apparatus of claim 3, the through path functions as a concave portion of the concave-convex fitting structure. Therefore, the lower member is formed with a convex portion that can be fitted to the through path. The reason why the guide member main body is penetrated through the through passage in the longitudinal direction is to reduce the weight of the guide member main body without impairing the strength. Further, although depending on the material constituting the guide member main body and the manufacturing method, for example, when a metal material such as aluminum is manufactured by extrusion, the metal material can be saved by the amount of the through path. Furthermore, since the air in the through passage functions as a buffer material, it is possible to expect an effect of reducing noise generated when polishing the pachinko balls.
[0012]
(Feature of the invention of claim 4)
The pachinko ball polishing apparatus according to the invention of claim 4 (hereinafter referred to as “the polishing apparatus of claim 4” as appropriate) is the polishing apparatus according to any one of claims 1 to 3, wherein the guide member further includes The upper member located in the upper part of a guide member main body, and the upper attachment / detachment structure provided between the said guide member main body and the said upper member are included.
[0013]
According to the polishing apparatus of the fourth aspect, in addition to the function and effect of the polishing apparatus of any one of the first to third aspects, the upper member can also be detached from the guide member main body by the desorption action of the upper desorption structure. It is envisaged that the upper member will wear or break, if not generally as much as the lower member. In such a case, the upper member can be replaced with a new one, which is more economical and reduces the amount of industrial waste compared to the case where only the lower member can be replaced.
[0014]
(Feature of the invention of claim 5)
The pachinko ball polishing apparatus (hereinafter referred to as “the polishing apparatus of claim 5”) according to the invention of claim 5 is the polishing apparatus of claim 4, wherein the upper member has the same structure as the lower member. And the upper desorption structure has the same structure as the lower desorption structure. The “same structure” means that the lower member can be used as it is as the upper member, and the upper member can be used as it is as the lower member, that is, both members can be used interchangeably.
[0015]
According to the polishing apparatus of the fifth aspect, in addition to the function and effect of the polishing apparatus of the fourth aspect, since the lower member and the upper member are interchangeable, the member to be manufactured is either the lower member or the upper member. Is enough. That is, since the number of parts can be reduced as compared with the case where the lower member and the upper member are manufactured separately, the manufacturing cost can be reduced accordingly.
[0016]
(Characteristics of the invention described in claim 6)
A pachinko ball polishing apparatus according to a sixth aspect of the invention (hereinafter referred to as “the polishing apparatus of the sixth aspect” as appropriate) is the polishing apparatus according to any one of the first to fifth aspects, wherein the guide is orthogonal to the through passage. The shape of the cross section of the member body can be constant regardless of the position of the cross section.
[0017]
According to the polishing apparatus of claim 6, in addition to the effects of the polishing apparatus of claims 1 to 5, when the guide member body is made of, for example, metal or synthetic resin, it is manufactured by extruding them. Is possible. Since the mold used for extrusion molding has a simpler structure than the mold used for injection molding or the like, the former can be procured at a lower cost than the latter. Inexpensive molds reduce the manufacturing cost of the guide member main body, and thus reduce the cost of the entire pachinko ball polishing apparatus.
[0018]
(Feature of the invention of claim 7)
The pachinko ball polishing apparatus according to the invention of claim 7 (hereinafter referred to as “the polishing apparatus of claim 7” as appropriate) is the polishing apparatus according to any one of claims 1 to 6, wherein the guide member body is made of metal. The back surface which is the surface on the opposite side to the said guide surface is comprised, and the back surface of the said guide member main body comprises a part of said conveyance tower outer wall surface. That is, the guide member main body is not located inside the transfer tower but constitutes a part of the outer wall of the transfer tower.
[0019]
According to the polishing apparatus of the seventh aspect, in addition to the function and effect of the polishing apparatus according to any one of the first to sixth aspects, a member for positioning the guide member main body in the transport tower is unnecessary. It can be said that such a member and the guide member main body are integrated. As a result, it is possible to reduce costs by reducing the number of parts, and by eliminating the need for the above members, it is possible to avoid inconveniences associated with thermal expansion due to the coexistence of such members and the guide member main body. That is, polishing of the pachinko balls by the guide member main body and the conveying belt via the polishing cloth is performed by rubbing the pachinko balls against the polishing cloth, but a large amount of heat is generated by the rubbing. This heat heats not only the guide member main body but also the above members to expand both of them. However, since the expansion coefficients of the two are generally different, a difference occurs in the degree of expansion, and stress due to the difference may lead to damage of the guide member main body, for example. Since the guide member main body according to the polishing apparatus of the seventh aspect does not require such coexisting members, it is possible to prevent inconvenience due to the difference in expansion coefficient.
[0020]

FIG. 8 is a view in which a conveyance belt and a polishing cloth are added to the CC cross-sectional view of the guide member shown in FIG.
[0021]
(Schematic structure of the transfer polishing device)
A pachinko ball conveying and polishing apparatus (hereinafter referred to as “polishing apparatus”) will be described with reference to FIGS. The polishing apparatus 1 is generally composed of a base portion 3 installed on a floor surface and a transfer tower 5 standing up from the base portion. The transport tower 5 includes a guide member 7, a polishing cloth 13 (see FIG. 3) mounted on the guide surface 9 of the guide member 7, and a transport belt 15. Reference numeral 19 shown in FIG. 3 denotes a guide roller for guiding the conveyor belt 15.
[0022]
(Conveyor belt structure)
As shown in FIGS. 1 to 4, the conveyor belt 15 is an endless belt wound around a lower roller 21 and an upper roller 23, and rotates with a motor 25 as a drive source. Further, it passes through the transport tower 5 on the forward path viewed from the lower roller 21 and passes through the belt cover 27 on the return path. The conveyor belt 15 has a conveyor surface 17 that comes into contact with a pachinko ball to be conveyed, and has sufficient elasticity to apply a pressing force to the pachinko ball. The material constituting the conveyor belt 15 is generally synthetic rubber, but may be a material other than synthetic rubber (for example, cloth material, synthetic leather material) or a composite thereof.
[0023]
(Guide member structure)
The guide member 7 will be described with reference to FIGS. The guide member 7 includes a guide member main body 31, an upper member 55 located at the upper part of the guide member main body 31, and a lower member 51 located at the lower part of the guide member main body 31. A substantially semicircular guide groove 11 capable of receiving pachinko balls in a line in a line along the conveying direction via a polishing cloth 13 is provided on the inner surface of the conveying tower 5 of the guide member 7, that is, on the guide surface 9 side. A plurality of lines (seven lines in this embodiment) are formed. As described above, the guide member 7 is composed of a plurality of members, but each guide groove 11 is formed over the entire members. A surface located on the side opposite to the guide surface 9 is a back surface 10.
[0024]
The guide member main body 31 may be made of synthetic resin, but is made of metal. In this embodiment, it was made of aluminum. Aluminum was mainly adopted because it is relatively light in weight, has an appropriate strength, and is easy to be extruded as described later. In the longitudinal direction of the guide member main body 31, a plurality of (six in this embodiment) through passages 33 are formed so as to penetrate therethrough. As shown in FIGS. 3 to 5, the through-passage 33 has a substantially square cross-sectional shape, but this may be circular or any other shape. As shown in FIG. 7, the width dimension of each through passage 33 is always constant, that is, the shape of the cross section is always constant. This point will be described later in connection with the manufacturing method. The through passage 33 is formed by first reducing the weight without impairing the strength of the guide member body 31, secondly saving the aluminum material used, and finally forming a part of the uneven fitting structure described later. It is for aiming.
[0025]
As shown in FIGS. 3 to 6, the guide member main body 31 includes a T-shaped slot 35 having a T-shaped cross section that is open at both ends in the width direction, in addition to the guide groove 11 and the through passage 33 described above. 36 is formed penetrating in the longitudinal direction, and is provided with substantially L-shaped presser pieces 37 and 38 that are erected from the end of the guide surface 9 and bent inward of the guide surface 9. The T-shaped slot 35 is a groove for allowing the slide screw 47 to be slidable and fixed in the longitudinal direction of the guide member main body 31, and the T-shaped slot 36 is configured to connect the slide screw 43 to the longitudinal direction of the guide member main body 31. It is a groove | channel for making it slidable and fixable. The main purpose of the holding pieces 37 and 38 is to prevent the both ends in the width direction of the polishing pad 13 mounted on the guide surface 9 from floating from the guide surface 9.
[0026]
The guide member main body 31 is preferably manufactured by extrusion molding. As described above, the guide member main body 31 includes the guide groove 11, the through passage 33, the T-shaped slots 35 and 36, and the presser pieces 37 and 38. The shape of the orthogonal cross section is constant regardless of the position of the cross section. That is, the shape of the cross section of the guide member main body 31 orthogonal to the through passage 33 is constant regardless of the position of the cross section. Solid aluminum can be manufactured by cutting or injection molding, but it can be manufactured by injection molding, but the former takes too much work and the latter is more complicated than extrusion molds. I must. Therefore, an extrusion molding method was adopted that requires relatively little effort and requires a relatively low cost for the mold.
[0027]
As shown in FIGS. 2 and 3, the guide member main body 31 is attached to the transport tower 5 by a hinge 41 so as to be freely opened and closed. The hinge 41 is attached by a screw 42 and a slide screw 43. The slide screw 43 can slide in the T-shaped slot 36 in the vertical direction (perpendicular to the plane of FIG. 3) and is tightened at an arbitrary position. It is configured to be fixable. On the other hand, on the opposite side of the guide member main body 31 from the hinge 41, a slide screw 47 is arranged which can slide in the T-shaped slot 35 in the vertical direction and can be fixed by tightening at an arbitrary position. Further, a shaft pin 45 provided on the main body of the transfer tower 5 and a swing arm 46 that can swing around the shaft pin 45 are provided. The swing arm 46 has a notch engageable with the slide screw 47 at the tip, and when the swing arm 46 swings forward from the state shown in FIG. 3, the engagement with the slide screw 47 is released. It is configured to be possible. When the swing arm 46 is engaged with the slide screw 47, the swing arm 46 is swung in the direction of the rear side of the paper in FIG. This engagement locks the guide member main body 31 to the main body of the transport tower 5. The back surface 10 of the locked guide member main body 31 constitutes a part of the outer wall surface of the transfer tower 5 as shown in FIGS. That is, the guide member main body 31 itself serves as a door for opening and closing the transport tower 5.
[0028]
Conventionally, there is a door for opening and closing the transfer tower, and the guide member main body is arranged on the inner surface of the door. However, according to the present embodiment, such a door is unnecessary. Since it is not necessary, the cost can be reduced by reducing the number of parts. Furthermore, if the guide member main body 31 is integrated with another member such as a door, inconvenience due to thermal expansion due to the coexistence of such another member and the guide member main body 31 can be avoided. . The heat generated with the pachinko ball polishing heats the other members as well as the guide member main body 31 and expands both, but generally the expansion coefficients of both differ, so a difference occurs in the degree of expansion, The stress due to the difference may lead to damage of the guide member main body 31. In order to prevent this damage, the door is unnecessary. Note that the guide member main body 31 in the present embodiment is configured by a single member so that it can be manufactured at once and does not require assembly, but it may be configured by a plurality of members arranged in the longitudinal direction. In the case of being constituted by a plurality of members, a coupling means for coupling both is required.
[0029]
(Upper member and lower member)
This will be described with reference to FIGS. Both the upper member 55 and the lower member 51 are made of synthetic resin. Although it may be made of metal, it is made of synthetic resin because the upper member 55 and the lower member 51 have a more complicated structure than the guide member main body 31, and therefore, synthetic resin material is injected, for example, This is because forming by forming is easier than forming and processing metal. The upper member 55 and the lower member 51 can be formed in different shapes. However, in order to reduce the types of manufacturing molds and to simplify the manufacturing procedure, the upper member 55 and the lower member 51 are used in this embodiment. Both members have the same shape. Therefore, in manufacturing, it is sufficient to manufacture only one of the upper member 55 and the lower member 51. For example, if the lower member 51 is manufactured, it can be used as the upper member 55 as it is. The reverse is also true. Since both members have the same shape, only the upper member 55 will be described in the following description, but the lower member 51 is also referred to when necessary for the description of the shape.
[0030]
The upper member 55 has a width dimension substantially the same as the width dimension of the guide member main body 31, and a part of the guide groove 11 is formed on the guide surface 57 side. As described above, the guide groove 11 is formed across the upper member 55, the guide member main body 31 and the lower member 51. The guide surface 57 of the upper member 55 is a gently curved surface (see FIG. 8) that tapers toward the tip (end opposite to the guide member main body 31). This is because the polishing cloth 13 attached to the guide surface 57 is not worn as much as possible as shown in FIG. That is, the pachinko balls are polished by rubbing them against the polishing cloth 13, but the rubbing cloth 13 is displaced in the vertical direction of FIG. 8 with respect to the upper member 55 by this rubbing. This deviation can be a major cause of wear of the polishing cloth 13, and therefore, the friction received by the displaced polishing cloth 13 from the upper member 55 is minimized. In addition, the code | symbol 60 shown in FIG. 4 has shown the engagement recessed part which comprises a part of the retaining structure 71 mentioned later.
[0031]
(Uneven fitting structure)
This will be described with reference to FIGS. Six convex portions 59 are formed on the end surface of the upper member 55 on the guide member main body 31 side. The shape of the cross section of each convex portion 59 is formed in a similar shape having a slightly smaller diameter than the shape of the cross section of the through passage 33. This is because when the upper member 55 and the guide member main body 31 are joined, the projections 59 are simply inserted into the through passages 33 to be positioned between them. Each convex portion 59 and each through passage 33 constitute an uneven fitting structure (upper detachable structure) 61 in the present embodiment. The concavo-convex fitting structure 61 having the above-described configuration has a structure that can be inserted and removed in the longitudinal direction of the guide member 7, but the configuration is mainly manufactured by extrusion molding the guide member main body 31, and then This is because it can be used as it is without any special post-processing. An uneven fitting structure 61 (lower detachment structure) is also formed between the guide member main body 31 and the lower member 51 in the same manner.
[0032]
(Retaining structure)
This will be described with reference to FIGS. The retaining structure 71 includes the engaging recess 60 on the side surface of the upper member 55 and the engaging member 73 described above. The engagement member 73 includes an L-shaped plate 75, a screw 77, and a trapezoidal slide portion 79. The L-shaped piece 75 is formed by bending a metal plate substantially at a right angle. The L-shaped piece 75 supports the trapezoidal slide portion 79 via an engagement piece 75 a formed to be able to engage with the engagement recess 60 and a screw 77. And supporting piece 75b. As shown in FIG. 4, the trapezoidal slide portion 79 is formed in a flat T shape that can slide in the vertical direction in the figure, and the trapezoidal slide portion 79 is slid and moved to a predetermined position. Has a role of fixing to the guide member main body 31 by tightening a screw 77. After the upper member 55 is fitted to the guide member main body 31 by the concave / convex fitting structure 61, the engaging member 73 is slid in the vertical direction, the engaging piece 75a is inserted into the engaging concave portion 60, and both are engaged. When engaged, the screw 77 is tightened to fix the trapezoidal slide portion 79 to the guide member main body 31. As a result, the upper member 55 cannot be removed from the guide member main body 31. Conversely, the upper member 55 can be removed from the guide member body 31 by loosening the screw 77 to release the engagement between the engagement piece 75 a and the engagement recess 60. The T-shaped slot 35 at the right end of the guide member main body 31 shown in FIG. 4 is also used to prevent it from coming off by the engaging member 73 (not shown). The same applies to the lower member 51. The reason why the retaining structure 71 is provided is that it is necessary because the upper member 55 and the guide member main body 31 can be attached and detached only by inserting and removing in the length direction. In this case, the retaining structure can be omitted.
[0033]
(Functions and effects peculiar to the present embodiment)
This will be described with reference to FIGS. According to the polishing apparatus 1, the pachinko ball sandwiched between the conveyance belt 15 and the guide member 7 via the polishing cloth 13 is conveyed in a predetermined direction by the rotation of the conveyance belt 15 in the conveyance tower 5. To do. The lower member 51 and the upper member 55 of the guide member 7 are exposed to the collision and rubbing of the pachinko balls through the polishing cloth 13 even though the polishing cloth 13 is interposed therebetween. Therefore, the lower member 51 and the upper member 55 may be worn or sometimes damaged, particularly in the former case. The worn or damaged lower member 51 is released from the guide member main body 31 by releasing the mounting action of the concave-convex fitting structure (lower detaching structure) 61, and another new lower member 51 is driven instead of the mounting action. Install by. Although the guide member main body 31 remains as it is, the guide member 7 can be continuously used by replacing the lower member 51. The same is true for the upper member 55. Therefore, since only the lower member 51 and the upper member 55 that are worn or damaged are discarded, it is very economical, and the amount of waste is much higher than when the entire guide member has to be discarded. Less is enough. Furthermore, the detachment of the lower member 51 (lower member 55) can be easily performed by the insertion / removal in the longitudinal direction by the concave / convex fitting structure 61 and the function of the retaining structure 71.
[0034]
