Description

[Detailed description of the invention] [Field of industrial application] This invention enables the entire spherical surface of a billiard ball to be polished uniformly and at high efficiency by increasing the contact pressure with the polishing cloth and soft polishing bristles. This invention relates to an automatic billiard ball polishing device.

[Conventional technology]

As an automatic polishing device for billiard balls, Jikoko 51
The one described in Publication No. -42436 is known. This device cleans billiard balls by immersing them in a cleaning tank that has a cleaning disk on the inner bottom, and rotating the billiard balls by the rotating action of this cleaning disk while bringing them into contact with a brush provided on the lid. At the same time, the billiard balls that have been cleaned are taken out of the cleaning tank and are inserted between polishing discs placed above and below to be polished. However, with this device, it is not possible to uniformly polish the entire surface of a spherical billiard ball, and at the same time, the polishing process is divided into multiple stages, and the billiard ball must be moved to a different location each time, which is inefficient.

In addition, Japanese Patent Application Laid-open No. 1982-2962 or Utility Model Application No. 1973
As described in Japanese Patent No. 47159, it is generally known to use three rolls for polishing spherical bodies such as billiard balls. However, when polishing billiard balls, it is necessary to polish the entire surface uniformly, increase the polishing time by increasing the residence time of the billiard balls between rolls, and reduce the contact pressure between the billiard balls and the polishing material. An important element is to make it larger.

However, in the former method described in JP-A No. 48-2962, the rotational speed of the three rolls is made different to achieve uniform polishing of the entire surface of the sphere, but the three rolls are tilted. Since the configuration in which the spheres are conveyed in a specific direction is adopted, the residence time of the spheres between the three rolls is short, and if this is to be increased, the length of the rolls must be increased.

In addition, in the latter method described in Japanese Utility Model Application Publication No. 48-47159, a pair of rolls, at least one of which is a brush roll, are provided in parallel at an appropriate interval, and a spiral is formed directly above the troughs of both rolls. Rolls are arranged, a golf ball is placed between the three rolls, and while the golf ball is transported by the rotation of the spiral roll, while the golf ball is transported by the three rolls, The golf ball is cleaned by the action of a brush installed on the surface of the roll. In this device, the golf ball is inserted into the groove of the spiral roll and conveyed by the rotation of the golf ball, so the golf ball remains stuck in the groove of the spiral roll, and the golf ball is transported. Rotation in any direction is inhibited. Also, like a golf ball, which has an uneven surface, it seems possible to remove soil, grass, etc. that have gotten into the grooves with the above-mentioned device, but in the case of billiard balls, It is necessary not only to clean the spherical surface, but also to polish it to make it shiny, which is difficult to do with the above-mentioned apparatus.

[The problem that the idea aims to solve]

The object of this invention is to polish the entire surface of a billiard ball uniformly and efficiently by increasing the contact pressure between the polishing cloth and the soft abrasive bristles.

The rolls of books are supported almost horizontally on a frame in parallel, and the three rolls are driven and rotated in the same direction by a drive device, so that the billiard balls sandwiched between the three rolls can be This automatic billiard ball polishing device is characterized in that it is configured to polish by rotating it in the direction of the ball and feeding it in the axial direction.

〔Example〕

Embodiments of the invention are shown in FIGS. 1-6.

Three rolls, a polishing roll _R1 , a feed roll _R2 , and a billiard ball rotating roll _R3 , are supported horizontally on a frame 1 in parallel with each other.

Billiard ball rotating roll R ₃ is located in the middle in plan view, polishing roll R ₁ is located in the middle in front view, and feed roll R ₂ is located above billiard ball rotating roll R ₃ . The three rolls R ₁ , R ₂ , R ₃ are as follows:
It is supported by frame 1.

On the outer peripheral surface of the polishing roll _R1 , a rough polishing cloth 2a,
A medium polishing cloth 2b and a finishing polishing cloth 2c are attached in this order.

Bristles 3 have a predetermined width on the outer peripheral surface of the feed roll R ₂ .
W ₂ is flocked in a spiral manner, and polishing soft bristles 4 are flocked to the portions where the bristles 3 are not flocked. The polishing bristles 4 are shorter than the bristles 3, and a guide groove 5 for the billiard ball B is formed between adjacent bristles 3.

As shown in FIGS. 1 and 4, the part of the polishing soft bristles 4 on the feed roll R ₂ is tapered so that the diameter gradually decreases from the input part A ₁ of the billiard ball b toward the discharge part A ₂ . It is shaped like this.

As shown in FIGS. 2 and 4, the bristles 6 on the outer peripheral surface of the billiard ball rotating roll R ₃ are in the opposite direction to the bristles 3 planted on the feed roll R ₂ and are further than this. The bristles are flocked in a gentle spiral, and in the area where the bristles 6 are not flocked, polishing soft bristles 7, which are slightly shorter than the bristles 6, are flocked in a spiral shape. For this reason, the billiard ball rotating roll _R3 has the above-mentioned feeding roll _R2 .
A groove 10 is formed in the opposite direction to the guide groove 5 and shallower than this. The width W ₃ of the bristles 6 flocked on this billiard ball rotating roll R ₃ is the width _{W 2} of the bristles 3 flocked on the feed roll R _2.
much narrower than.

As shown in FIGS. 4 and 6, the pulley 8 attached to the polishing roll _R1 and the drive motor
A belt 12 is hung between a pulley 11 attached to a drive shaft 9 of _M1 , and the polishing roll _R1 is driven and rotated by a drive motor _M1 .

A belt 16 is hung between the pulley 13 attached to the billiard ball rotating roll _R3 and the pulley 15 attached to the drive shaft 14 of the drive motor _M2 , and the billiard ball rotating roll
A belt 19 is hung between another pulley 17 attached to R ₃ and a pulley 18 attached to feed roll R ₂ , and feed roll R ₂ and billiard ball rotation roll R ₃ are driven by a drive motor. It is driven and rotated by _M2 .

As shown in FIG. 5, the above three rolls R ₁ , R ₂ , R ₃ all rotate in the same direction,
Three rolls R ₁ , by the rotation of polishing roll R ₁ ,
Billiard ball B sandwiched between R ₂ and R ₃ rotates in a direction in which it is pressed against billiard ball rotating roll R ₃ . However, the three rolls R ₁ , R ₂ , R ₃
The rotational speed of the polishing roll _R1 is much higher than that of the other two rolls _R2 and _R3 .

Then, when the billiard ball B is thrown into the throwing part A ₁ at one end of the three rolls R ₁ , R ₂ , R ₃ , the billiard ball B is thrown between the three rolls R ₁ , R ₂ , R ₃ . At the same time, a portion of the billiard ball B enters into the guide groove 5 of the adjacent bristles 3 that are spirally flocked on the feed roll _R2 .

As shown in FIG. 5, when the billiard ball B is sandwiched between the three rolls R ₁ , R ₂ , R ₃ , each polishing roll of the feed roll R ₂ and the billiard ball rotating roll R ₃ is The soft bristles 4 and 7 are elastically deformed, and the billiard ball B is formed by the rough polishing cloth 2a of the polishing roll _R1 .
The polishing bristles 4 and 7 are in contact with each other with a predetermined contact pressure.

When the three rolls R ₁ , R ₂ , and R ₃ rotate in the same direction in this state, the billiard balls B are sent in the axial direction with a portion of the ball B entering the guide groove 5 of the feed roll R ₂ . , the billiard ball B is moved by the rotating action of the polishing roll _R1 to the feeding roll.
It is pressed against the soft polishing bristles 4 and 7 of R ₂ and the billiard ball rotation roll R ₃ and rotated together.

Since the helical direction of the bristles 3 provided on the feed roll R ₂ and the helical direction of the bristles 6 provided on the billiard ball rotating roll R ₃ are opposite to each other, the billiard ball rotating roll R ₃ is Billiard balls B, which are being sent in the axial direction by the feed roll _R2 , compete to be sent in the opposite direction.

However, billiard ball rotation roll R ₃ bristles 6
The width W ₃ of the feed roll R ₂ is much narrower than the width W ₂ of the bristles 3 of the feed roll R 2 , and the bristles 6 of the former have a gentler spiral shape than the bristles 3 of the latter. Since the guide groove 5 of the roll _R2 is deeper than the groove 10 of the billiard ball rotating roll _R3 , the feeding action by the feed roll _R2 is greater than that of the billiard ball rotating roll _R3 .

Therefore, the billiard ball B can be rotated in any direction by the synergistic effect of the hooking action of the bristles 6 spirally provided on the billiard ball rotating roll _R3 and the co-rotating action of the polishing roll _R1 . It is sent along the guide groove 5 of the feed roll _R2 while being rotated.

In this way, due to the synergistic effect of the co-rotating action by the polishing roll _R1 and the hooking action by the billiard ball rotating roll _R3 , the billiard ball B is rotated in any direction while being rotated in the axial direction of the roll. The polishing cloths 2a, 2b, 2c are fed along the polishing roll _R1 and are attached to the polishing roll R1, and the feed roll _R2
The entire spherical surface is uniformly polished by the polishing bristles 4 and 7 that are flocked on the billiard ball rotation roll R ₃ , respectively, and the three rolls R ₁ , R ₂ , R ₃ are formed.
It is discharged from the discharge part _A2 at the other end.

Also, since the rotation directions of the three rolls R ₁ , R ₂ , and R ₃ are the same, the billiard balls B sandwiched between the three rolls R ₁ , R ₂ , and R ₃ rotate in the same direction. The billiard balls B are rotated together and are not bitten between two adjacent rolls or thrown out from between the two rolls, and therefore the billiard balls B are sent in the axial direction of the rolls. In between, it is polished smoothly.

In addition, since the part of the polishing soft bristles 4 on the feed roll R ₂ is tapered so that the diameter gradually decreases from the billiard ball B input part to the discharge part, ,
The contact pressure between the polishing cloths 2a, 2b, 2c and the soft polishing bristles 4, 7 gradually decreases as polishing progresses, so that rough polishing gradually shifts to final polishing.

[Effect of idea]

The present invention uses a drive device to drive and rotate three rolls, a polishing roll, a feed roll, and a billiard ball rotation roll, in the same direction, so that the billiard balls sandwiched between the three rolls can be freely rotated. While rotating in the direction of the roll and feeding it in the axial direction of the roll,
Since the billiard ball is polished using a polishing cloth attached to the polishing roll and each polishing soft bristles flocked to the feed roll and the billiard ball rotating roll, conventional automatic polishing was considered difficult. It becomes possible to polish the entire spherical surface of a billiard ball uniformly and with high efficiency by increasing the contact pressure between the polishing cloth and the polishing bristles.
