[0001]
BACKGROUND OF THE INVENTION
The present invention is provided with a polishing apparatus for mixing a granular abrasive material in a game medium and lifting it while stirring to polish the game medium, and polishing for separating the dust adhering to the abrasive material from the abrasive material The present invention relates to a regenerator of a material regeneration processing apparatus.
[0002]
[Prior art]
Conventionally, as a regenerator of an abrasive material recycling apparatus, for example, those shown in Japanese Patent Application Laid-Open Nos. 10-76066 and 9-38325 are known. The former publication discloses a regenerator provided with a plurality of stirring rods and the like that forcibly agitate the abrasive during rotation of the roller and separate the dust around the roller that is driven to rotate by a drive motor. The latter publication discloses a regenerator in which a polishing particle receiving portion having a shelf-like surface is provided at a position where the flowing abrasive material hits, and dust is separated by collision of the abrasive material with the abrasive particle receiving portion. .
[0003]
[Problems to be solved by the invention]
However, since the conventional regenerator disclosed in the former publication is based on the premise that it is operated by a drive motor as a power source, the number of parts increases, the assembly man-hour increases, and the apparatus itself becomes expensive. At the same time, there is a problem that running costs due to power consumption during operation increase. In addition, there is a problem that dust is mixed into the drive motor and causes troubles such as motor stoppage.
[0004]
Further, in the conventional regenerator disclosed in the latter publication, the cost can be reduced by not using a drive motor. However, the abrasive grain receiving portion that collides with the abrasive is closed with a lid member at the opening window portion. In other words, it is simply a flat plate structure with a smooth surface connected to substantially the same plane. Therefore, there is a possibility that the dust stuck to the surface of the abrasive cannot be sufficiently separated.
[0005]
The present invention has been made by paying attention to the above-described problems of the prior art, and can be reduced in cost without using any special power source such as a drive motor. It is an object of the present invention to provide a regenerator for an abrasive material reprocessing apparatus that can efficiently separate the material and can regenerate an abrasive material having a good polishing ability.
[0006]

[0025]
As shown in FIG. 1, the regenerator 11 has a separation receiving unit 20 that repels an abrasive that naturally falls in the flow path 5 and separates dust from the abrasive. The separation receiving unit 20 flows down without staying on the separation receiving unit 20 after the abrasive material collides once at a position where all of the abrasive material naturally falling from above the flow-down path 5 can be received. Are arranged in a state of being inclined downward.
[0026]
The flow-down path 5 is formed by connecting the upper flow-down path 5a and the main flow-down path 5b on the upstream side thereof such that the axes extending in the vertical direction are shifted in parallel to each other. A collision wall 5c that is bent obliquely downward toward the main flow path 5b side with respect to the axial center (vertical direction) of the upper flow path 5a is provided at the connecting portion so that the abrasive material collides in the middle of dropping. A rectangular attachment opening 5d is formed in almost the entire area of the collision wall 5c, and the regenerator 11 is detachably disposed in the attachment opening 5d.

They are lined up in the state they are created.
[0028]
As shown in FIG. 2, a plurality of comb-shaped slit plates 30 (see FIG. 3) prepared by arranging a plurality of elastic pieces 31 in a line as a component of the separation receiving unit 20 are prepared. The slit plate 30 is formed, for example, by laser processing a metal plate, and each of the plurality of elastic pieces 31 can be elastically deformed, and is smaller than the particle size of the abrasive between the side edges extending in the longitudinal direction. The slits 32 are arranged so as to allow the passage of dust though the width. Further, the side edge of each elastic piece 31 is shaped into a sharp edge.
[0029]
In the present embodiment, three such slit plates 30 are prepared, and these are arranged in a multi-stage between an upper edge plate (see FIG. 4) 35 and a lower edge plate (see FIG. 5) 36 having an L-shaped cross section. Overlapped and combined. Here, as shown in FIG. 2, the distal end side 31 a serving as the free end of each elastic piece 31 in the upper slit plate 30 floats from the proximal end side 31 b of each elastic piece 31 in the lower slit plate 30. Combined.
[0030]
A pair of engaging protrusions 33 that are positioned when they are coupled to each other, and a pair of engaged grooves 34 that match the engaging protrusions 33 are formed at both end portions of each slit plate 30. In this embodiment, three slit plates 30 are prepared. However, the present invention is not limited to this, and four or five or more slit plates 30 may be stacked depending on the size of the separation opening 22 of the housing 21. Also good.
[0031]
Each of the slit plates 30 stacked in a multi-stage shape between the upper edge plate 35 and the lower edge plate 36 is integrally attached to the inside of the housing 21 so as to cover the separation opening 22 of the housing 21 as it is. Configured as a unit. As described above, the separation receiving portion 20 configured as described above is provided in the middle of the flow-down path 5 with the distal end side 31a serving as the free ends of the plurality of elastic pieces 31 inclined downward. Thus, it is detachably disposed on the collision wall 5c, which is a position that can receive all the abrasives that fall naturally.
[0032]
Specifically, as shown in FIGS. 1 and 6 to 9, the upper flange 23 that extends and bends further upward from the upper end edge of the housing 21 is attached to the upper flow path 5 a and forms a toggle. 24 is provided with a detachable hook 23a. The locking member 24 is further supported by a pivot link 25 fixed to the upper flow path 5a so as to be pivotable, and can be pivoted by another pivot 26a. The striker 27a is installed between the swinging ends of the pair of attached telescopic bars 27.
[0033]
On the other hand, a lower flange 28 bent and extended further downward from the lower end edge of the housing 21 is formed so as to be detachably inserted into the lower end edge side of the mounting opening 5d. Further, on both side walls of the housing 21, it is possible to engage and disengage with locking grooves 5e recessed at both side edges of the mounting opening 5d, and a butterfly for preventing fall when the locking tool 24 is removed. A locking screw 28a with a nut is attached.
[0034]
In addition, a communication port 29 is formed in a tubular shape in the housing 21 so as to communicate with the back wall facing the front side covered with the plurality of elastic pieces 31 to the dust collector 12 side for sucking dust separated from the abrasive. It is installed. As shown in FIG. 11, the front end 6a of the suction hose (communication pipe) 6 is connected to the communication port 29 in an airtight manner. On the other hand, the base end port 6b of the suction hose 6 is connected to the dust collector 12 through a connecting pipe 6c.
[0035]
Next, the operation of the regenerator 11 according to the present embodiment will be described.
In FIG. 11, the polishing apparatus 1 conveys pachinko balls collected in the lower tank 2 from the ball tank to the lower end side of the polishing cylinder 3 and stores them in the lower tank 2 within the polishing cylinder 3. The pachinko balls are mixed with the granular abrasives, and the pachinko balls and the abrasives are lifted and agitated by a screw that is rotationally driven in the polishing cylinder 3, and the pachinko balls are polished between them.
[0036]
The pachinko balls that have been polished are separated from the abrasive by the separation mechanism in the upper tank 4, and then circulated through the game medium circulation path in the gaming machine island to be supplied again to the pachinko machines and the ball rental machines. On the other hand, after the dust is separated by the abrasive recycling apparatus 10, the abrasive is again used for polishing pachinko balls. In the abrasive recycling apparatus 10, first, dust attached to the abrasive is separated by the regenerator 11, and the separated dust is collected by the dust collector 12.
[0037]
The abrasives separated from the pachinko balls by the separation mechanism in the upper tank 4 naturally fall down the flow path 5, and the individual abrasives in the fall of the regenerator 11 disposed on the collision wall 5 c. It is bounced by colliding with the receiving part 20 for separation one by one. That is, as shown in FIG. 10, the abrasive material collides with the elastic piece 31 of the separation receiving portion 20, but at the time of such collision, the elastic piece 31 is elastically deformed (arrow 2 in the figure), Since the abrasive is bounced up by the repulsive force (arrow (3) in the figure), the impact increases the separation of dust from the surface of the abrasive.
[0038]
The dust separated from the abrasive is discharged through the slits 32 between each of the plurality of elastic pieces 31, but as described above, the elastic piece 31 is elastically deformed when colliding with the abrasive. Therefore, along with this, the width of the slit 32 is repeatedly expanded. Thereby, it is possible to reliably prevent a situation in which dust is clogged in the slit 32.
[0039]
As shown in FIG. 2, the separation receiving portion 20 can be easily configured by superposing three comb-like slit plates 30 formed by arranging a plurality of elastic pieces 31 in a row in a multistage manner. Can do. According to such a separation receiving portion 20, as shown in FIG. 5B, the distal end side 31 a serving as the free end of each elastic piece 31 in the upper slit plate 30 corresponds to each elasticity in the lower slit plate 30. Since they are coupled to each other in a state of being lifted from the base end side 31b of the piece 31, each abrasive material is repelled separately in a wider range without losing any elastic deformation of the elastic piece 31 in each slit plate 30. Is possible.
[0040]
In addition, at the stepped portion on the tip side of each slit plate 30, if the abrasive collides with the edge portion, it can be more directly separated so as to scrape off dust from the surface of the abrasive. Further, as shown in FIG. 1, the separation receiving part 20 is disposed in a state in which the distal end sides 31 a of the plurality of elastic pieces 31 are inclined downward, so that the abrasive material repelled on the separation receiving part 20 After all, however, it is possible to prevent the abrasive from falling on the separating receiving portion 20 and falling. Further, by disposing on the collision wall 5c that receives all the abrasive that naturally falls in the middle of the flow path 5, it is possible to prevent supply of the abrasive from which dust has not yet been removed.
[0041]
8 and 9, in order to dispose the separation receiving portion 20 on the collision wall 5c of the flow-down path 5, first, the separation opening 22 of the housing 21 is aligned with the mounting opening 5d of the collision wall 5c. While the lower flange 28 of the housing 21 is inserted into the lower end edge side of the mounting opening 5d, the locking screws 5a with wing nuts screwed to the both side walls of the housing 21 are engaged with the locking grooves 5e at the both side edges of the mounting opening 5d. Hang on. In this state, the separation opening 22 of the housing 21 and the attachment opening 5d of the collision wall 5c are brought into close contact with each other.
[0042]
Subsequently, in a state where the hook 23a on the upper flange 23 of the housing 21 is hooked on the striker 27a of the locking tool 24 on the flow path 5 side, the operation lever 26 is tilted to form a toggle at the engagement site. Finally, the locking screw 28a with a wing nut is firmly tightened and fixed securely. With such a locking tool 24 and the like, the separation receiving portion 20 can be easily attached to and detached from the flow-down path 5, and the regenerator 11 can be easily and quickly installed and maintained.
[0043]
In the regenerator 11, the dust separated from the abrasive passes through the slits 32 between the elastic pieces 31, and is then connected via the suction hose 6 that is connected to the communication port 29 in the housing 21. Dust is collected by suction to the dust collector 12 side. As described above, according to the regenerator 11, the cost can be reduced without using any special power source such as a drive motor, and the dust can be efficiently separated from the abrasive. It is possible to recycle a good abrasive material.
[0044]
The embodiments of the present invention have been described above with reference to the drawings. However, the specific configuration is not limited to the above-described embodiments, and the present invention can be changed or added without departing from the scope of the present invention. Included in the invention. For example, although the plurality of elastic pieces 31 are arranged in a straight line, for example, a plurality of elastic pieces bent in a wave shape or a zigzag shape are arranged in a state in which slits are generated between them. Also good. Furthermore, embossing, protrusions, grooves, or the like that increase the coefficient of friction with the abrasive may be further processed on the surfaces of the plurality of elastic pieces.
[0045]
【The invention's effect】
According to the regenerator of the abrasive material reprocessing apparatus according to the present invention, the abrasive material separated in advance from the game medium naturally falls down the flow path, and the individual abrasive materials are arranged in the flow path during the fall. The elastic piece is elastically deformed at the time of such collision, and the elastic surface repels the abrasive material by the repulsive force. The separation of dust from is increased.
[0046]
In addition, the dust separated from the abrasive is discharged through the slits between each of the plurality of elastic pieces, but as described above, the elastic pieces are elastically deformed when colliding with the abrasive. For this reason, the expansion of the slit width is repeated accordingly. Thereby, the situation where dust is clogged in the slit can be surely prevented.
